DETAILED DESCRIPTION OF THE EMBODIMENTS

[0060] A combined cabinet is disclosed according to the present application, where a user can assemble the combined cabinet meeting requirements by using multiple single cabinets, and the single cabinets are communicated with each other.

[0061] Technical solutions in the embodiments of the present application are clearly and completely described hereinafter in conjunction with the drawings in the embodiments of the present application. Apparently, the embodiments described in the following are only some embodiments of the present application, rather than all embodiments. Any other embodiments obtained by those skilled in the art based on the embodiments in the present application without any creative effort shall fall within the protection scope of the present application.

[0062] In description of the present application, it should be understood that an orientation or a position relation indicated by terms such as “upper”, “lower”, “left”, “right” or the like is described based on an orientation or a position relation shown in the drawings, and is only used for describing the present application and simplifying the description, rather than instructing or implying that a device or element related to the terms has a specific orientation or is constructed and operated in a specific orientation. Therefore, the terms should be not construed as limitations to the present application.

[0063] The combined cabinet in the present application is an assembly of single cabinets. Two adjacent single cabinets can be communicated with each other through a first passage opening 1. Goods in the respective single cabinet can enter into the adjacent single cabinet through the first passage opening 1. Therefore, the interior of the combined cabinet is a communicated whole. Users can assemble the combined cabinet according to specific capacity requirements. Different capacity requirements can be met by increasing or decreasing the number of single cabinets. Moreover, the adjacent single cabinets can communicate with each other through the first passage opening 1, so that the stored goods can be transferred from the designated single cabinet, thus facilitating goods fetching.

[0064] Furthermore, a goods storage plate 5 is arranged in each single cabinet, and the goods storage plate 5 is used for carrying goods. A driving member 2 is arranged on the goods storage plate 5. The passage opening includes a first passage opening 1. The first passage opening 1 is located downstream from the driving member 2. The driving member 2 is configured to push the goods on the goods storage plate 5 off the goods storage plate 5, so that the goods enter the next single cabinet through the first passage opening 1 under the action of gravity. The combined cabinet in this application is described in detail in the following with reference to specific embodiments.

First Embodiment

[0065] The combined cabinet is formed by stacking multiple single cabinets. That is, the combined cabinet in this embodiment formed by stacking the single cabinets layer by layer. Referring to FIG. 1 to FIG. 16, FIG. 1 to FIG. 16 all belong to the combined cabinet formed by stacking.

[0066] The single cabinets can be arranged horizontally or obliquely. If the single cabinets are inclined, the combined cabinet formed thereby is in the form shown in FIG. 12. This arrangement is suitable for inclined spaces or artistic decorations. It can be seen from FIG. 12 that if the goods in the single cabinet of the highest layer are to be taken out, the driving member 2 in the single cabinet of the highest layer can drive the goods to move obliquely downward and then fall onto the goods storage plate 5 of the single cabinet of the intermediate layer. Then, the driving member 2 in the single cabinet of the intermediate layer drives the goods to move obliquely downward and enter the single cabinet of the lowest layer through the first passage opening 1. Finally, driven by the driving member 2 in the single cabinet of the lowest layer, the goods are moved out from the first passage opening 1 of the single cabinet of the lowest layer. It should be noted that, in this embodiment, the goods storage plate 5 is inclined, and in order to prevent the goods from sliding down undesirably, the driving member 2 can be a spiral push rod. In a natural state, the goods are stuck in a spiral structure of the spiral push rod. When the goods need to be moved, the spiral push rod rotates for one circle, and the goods are pushed by a pitch distance.

[0067] The goods storage plate is arranged obliquely or horizontally. If red wine is to be placed, it is necessary to select an inclined goods storage plate to place red wine so that the oak stopper can be immersed in red wine.

[0068] The size of the single cabinet is variable. Reference can be made to FIG. 13 to FIG. 14. In FIG. 13, a volume of each single cabinet gradually increases from bottom to top, and the single cabinets are left-justified. The first passage openings 1 of the layers are vertically aligned. If it is required to obtain the goods in the single cabinet of the highest layer, all the first passage openings 1 in the three layers of single cabinets are opened, the driving member 2 in the single cabinet of the highest layer drives the goods towards the corresponding first passage opening 1, so that the goods are moved out through the three first passage openings 1 in turn. In FIG. 14, the volume of each single cabinet gradually increases from bottom to top, and the single cabinets are middle-justified. In addition, the first passage opening 1 is arranged in the middle of the single cabinet of each layer. Then the left and right driving members 2 can drive the goods towards the middle, so that the goods can move through the first passage opening 1. The specific process is not repeated here.

[0069] In FIG. 15, the volume of each single cabinet gradually decreases from bottom to top, and the single cabinets are right-justified. In addition, it should be noted that, in FIG. 15, the left and right sides of the driving member 2 are each provided with the first passage opening 1, that is, two first passage openings for each single cabinet are provided. In this way, the driver 2 can drive the goods to the left and right sides, so that the goods can be moved out. The configurations of the single cabinet of the intermediate layer being the largest or smallest, one first passage opening 1 or two first passage openings 1 or multiple first passage openings 1 being provided in the single cabinet of each layer, and the single cabinets of the layers being misaligned with each other belong to the variants based on FIG. 13 to FIG. 15, and all fall within the protection scope of “the combined cabinet formed by stacking multiple single cabinets” in this application.

[0070] Further, the front panel of each single cabinet can be transparent, which is convenient for customers to observe the goods in the single cabinet through the front panel. If private or important goods are stored in the single cabinet, the front panel can be opaque. It should be noted here that the “front panel” mentioned in this specification refers to the end panel facing customers in the single cabinet. Referring to FIG. 16, the combined cabinet of FIG. 16 is a three-layer cabinet. The three layers of single cabinets are aligned to the left. A left side of the three layers of single cabinets is the side with the front panel. Therefore, the three layers of single cabinets are aligned to the side with the front panel. In addition, the front panel of the single cabinet on each layer is inclined outward from bottom to top. Preferably, the inclination angle of the front panel gradually increases from the lowest layer to the highest layer. With this arrangement, it is convenient for customers to observe the goods in the single cabinet from bottom to top. In addition, when the goods in the single cabinet of a higher layer are transferred to the single cabinet of a lower layer, the goods can slide along the inclined front panel, thus ensuring the movement stability of goods.

[0071] A cross-section of each single cabinet can be a polygon, including regular polygon and irregular polygon. Specifically, the cross-section can be a rectangle, as shown in FIG. 1, FIG. 8, FIG. 12, FIG. 13, FIG. 14 and FIG. 15; or a square, as shown in FIG. 2; or a diamond, as shown in FIG. 11; or a regular hexagon, as shown in FIG. 3, FIG. 4, FIG. 5 and FIG. 6; or an irregular hexagon, as shown in FIG. 9 and FIG. 10.

[0072] If the single cabinets are arranged in a matrix, a cabinet wall can be formed. The cabinet wall can be used as an ornament or a partition wall. Referring to FIG. 1 to FIG. 11, If the cross-section of each single cabinet in the matrix combined cabinet is rectangular or square, as shown in FIG. 1, FIG. 2 and FIG. 8, then a bottom plate of an upper single cabinet is attached to a top plate of a lower single cabinet. The two plates attached to each other are horizontal plates. The first passage opening 1 for goods to pass extends through the bottom plate and the top plate which are attached to each other. Goods in the upper single cabinet enter the lower single cabinet through the first passage opening 1. If the driving member 2 in each single cabinet is substantially parallel to the front panel of the single cabinet, the driving direction of the driving member is parallel to the front panel, as shown in FIG. 1 and FIG. 8. The driving member 2 in the single cabinet may also be substantially perpendicular to the front panel of the single cabinet, that is, the driving direction is perpendicular to the front panel, as shown in FIG. 2.

[0073] The combined cabinet can be a regular polyhedron or an irregular polyhedron. If the cross section of the single cabinet in the matrix combined cabinet is a regular hexagon, a diamond or an irregular hexagon, as shown in FIGS. 3 to 6, FIG. 11, FIG. 9 and FIG. 10, then the upper single cabinet is placed between two adjacent single cabinets in the lower layer. A lower left side plate of the upper single cabinet is attached to an upper right side plate of the lower left single cabinet. A lower right side plate of the upper single cabinet is attached to an upper left side plate of the lower right single cabinet. The two sets of attached plates are inclined plates, and are each provided with the first passage opening 1 extending therethrough for goods to pass through. That is, the goods in the upper single cabinet can enter the lower left single cabinet through the first passage opening 1 on the left, and can enter the lower right single cabinet through the first passage opening 1 on the right. In these matrix combined cabinets, the driving member 2 may also be substantially perpendicular or parallel to the front panel of the single cabinet. If the driving member 2 is substantially perpendicular to the front panel of the single cabinet, the driving direction is perpendicular to the front panel. If the driving member 2 is substantially parallel to the front panel of the single cabinet, the driving direction is parallel to the front panel.

[0074] In the matrix combined cabinet, the goods in any single cabinet can only be moved out from the lowest single cabinet, which is convenient for customers to fetch the goods. An upper automatic shutter 4 is arranged at the first passage opening 1. The automatic shutter 4 is used to control the opening and closing of the first passage opening 1. Customers can choose the single cabinet on the lowest layer from which the goods can be delivered out. Referring to FIG. 7, if the goods in cabinet B on the top layer are to be delivered out from cabinet H on the lowest layer, the moving path of the goods can be: B-D-H; if the goods in cabinet B on the top layer are to be delivered out from cabinet I on the lowest layer, the moving path of the goods can be: B-D-I, or B-E-I; if the goods in cabinet B on the top layer are to be delivered out from cabinet J on the lowest layer, the moving path of the goods can be: B-E-J. It should be noted that the passage opening on the single cabinet on the lowest layer is the outlet.

[0075] The automatic shutter 4 is telescopic or pivotable. In this embodiment, the automatic shutter 4 is preferably pivotable. That is, the automatic shutter 4 is hinged at the first passage opening 1. The automatic shutter 4 can open or close the first passage opening 1 when it rotates. That is, if the automatic shutter 4 rotates in one direction to block the first passage opening 1, the first passage opening 1 closed. If the automatic shutter 4 rotates in the other direction and leaves the first passage opening 1, the first passage opening 1 opened. In addition, the inclination of the automatic shutter 4 may affect the sliding speed of goods on the automatic shutter 4.

[0076] For example, if the sliding speed of goods passing through the first passage opening 1 is required to be increased, the automatic shutter 4 is pivoted to a position at a large inclination angle, and the automatic shutter 4 serves as an acceleration guide plate. If the sliding speed of goods passing through the first passage opening 1 is required to be reduced, the automatic shutter 4 is pivoted to a position at a small inclination angle, and the automatic shutter 4 serves as a deceleration guide plate. In actual use, for some fragile goods, the sliding speed of goods can be reduced. For some non-fragile goods, the sliding speed of goods can be appropriately increased.

[0077] If the driving direction of the driving member 2 in the single cabinet is perpendicular to the front panel, the first passage opening 1 located downstream from the driving member 2 can be a large one, so that the middle part of the automatic shutter 4 can be hinged in the first passage opening 1, as shown in FIG. 2 and FIG. 5. If the driving direction of the driving member 2 in the single cabinet is parallel to the front panel, the first passage opening 1 located downstream from the driving member 2 has to be a small one due to the space limitation, and the automatic shutter 4 is arranged at one side of the first passage opening 1, as shown in FIG. 1, FIG. 3, FIG. 4, FIG. 6 and FIG. 8.

[0078] In addition to fetching the goods from the single cabinet on the lowest layer, it is also possible to fetch the goods directly from the target single cabinet. For example, in this embodiment, a cabinet door is arranged on the front panel of each single cabinet. Goods can be taken out directly from the single cabinet after the cabinet door is opened. In the case that the matrix combined cabinet is used as a partition wall, those on one side of the partition wall can use the combined cabinet, and those on the other side of the partition wall can also use the combined cabinet. In addition, the cabinet doors of a part of single cabinets of the combined cabinet can open toward one side of the partition wall, and this part of single cabinets can be used by people on this side of the partition wall. The cabinet doors of another part of the single cabinets can open toward the other side of the partition wall, and this another part of the single cabinets can be used by people on the other side of the partition wall.

[0079] In addition to the above automatic shutter 4 serving as a guide plate for goods, an adjusting plate 3 can be added to further guide the goods. The adjusting plate 3 is arranged downstream from the driving member 2 and hinged to a side plate of each single cabinet. It should be noted that the “side plate” here refers to a plate that intersects the front panel in the single cabinet. After the goods are driven off the goods storage plate 5 by the driving member 2, the goods fall onto the adjusting plate 3 under the action of gravity, and then the adjusting plate 3 guides the goods into the corresponding first passage opening 1. This arrangement can ensure the smooth transfer of goods. In addition, the sliding speed of the goods can be controlled by adjusting the inclination of the adjusting plate 3.

[0080] For matrix combined cabinets, two or more combined cabinets can be assembled together. The single cabinets of one combined cabinet are communicated through the first passage opening 1, and the adjacent two combined cabinets are also communicated through the first passage opening 1. In addition, the goods are introduced into the adjacent combined cabinet through the adjusting plate 3. Referring to FIG. 8, FIG. 8 shows a two-sided matrix combined cabinet. The adjusting plate 3 faces the rear combined cabinet. If the goods driven by the driving member 2 fall on the adjusting plate 3, the adjusting plate 3 guides the goods into the rear combined cabinet.

[0081] It should be noted that the adjusting plate 3 can be hinged on the side plate of the single cabinet through a universal joint 8, as shown in FIG. 14.

[0082] Referring to FIG. 3, FIG. 4 and FIG. 6, the goods storage plate 5 is supported by a support rod 6, the support rod 6 extends along the driving direction of the driving member 2, and the goods storage plate 5 can move along the support rod 6. The support rod 6 is equivalent to a guide rod for the goods storage plate 5. After the goods storage plate 5 is driven by the driving device, the goods storage plate 5 moves along the support rod 6. With this arrangement, it is convenient to adjust the position of the goods storage plate 5, so that the goods on the goods storage plate 5 can smoothly pass through the first passage opening 1 on the single cabinet under drive of the driving member 2. The driving device for driving the goods storage plate 5 can be a motor, a screw rod, or a hydraulic mechanism.

[0083] Multiple goods storage plates 5 may be arranged vertically along the gravity direction, as shown in FIG. 3, FIG. 4 and FIG. 6, so as to further meet different requirements of users. In addition, the user can set the types of goods stored in each goods storage plate 5 according to requirements. For example, the freshest goods are stored on the goods storage plate 5 of the first layer, relatively fresh goods are stored on the goods storage plate 5 of the second layer, and goods almost expiring are stored on the goods storage plate 5 of the third layer. As time goes by, if goods on the goods storage plate 5 of the first layer are not sold, and the freshest goods become relatively fresh goods, then the just-turned relatively fresh goods can be automatically transferred from the goods storage plate 5 of the first layer to the goods storage plate 5 of the second layer. The specific operation is as follows: the goods storage plate 5 of the second layer is driven to move out, and then the driving member 2 on the goods storage plate 5 of the first layer pushes the goods on the goods storage plate 5 of the first layer onto the goods storage plate 5 of the second layer, and then the goods storage plate 5 of the second layer retracts to reset.

[0084] The passage includes a first passage opening 1 and a second passage opening 9. The second passage opening 9 is arranged on the extension line of the driving member. The goods on the goods storage plate can be driven by the driving member to enter the adjacent single cabinet through the second passage. For the combined cabinet having a matrix arrangement, if the driving direction of the driving member in the combined cabinet is along the lateral direction, the second passage opening 9 is configured to communicate two adjacent single cabinets in the lateral direction. Goods on the goods storage plate in the left single cabinet can enter the goods storage plate of the right single cabinet through the second passage opening 9 under drive of the driving member. In this embodiment, the single cabinets on the same layer are communicated with each other. In this way, the outflow path of goods becomes more diversified. In addition, the goods storage plate can enter the adjacent single cabinet through the second passage opening 9 under drive of the driving device, that is, the goods storage plate can move between the single cabinets on the same layer.

[0085] Further, multiple driving members 2 may be provided side by side, that is, in the same horizontal plane, there are multiple driving members 2 arranged side by side. Correspondingly, multiple goods storage plates 5 are also provided side by side to meet more requirements of users, as shown in FIG. 2 and FIG. 5.

[0086] It should be noted that the driving member 2 may be a push rod. The push rod may be a spiral push rod, a telescopic rod driven by a screw rod, a telescopic rod driven by a driving chain, or a conveyor belt. There is no specific limitation on the structure of the push rod in this specification, as long as the push rod can push the goods on the goods storage plate 5 off the goods storage plate 5. Any appropriate structure of the push rod falls into the scope of protection of this specification.

Second Embodiment

[0087] Each single cabinet may have a cone structure. Single cabinets with a cone structure can be combined into a fan shape, as shown in FIG. 18. Each side single cabinet is communicated with the middle single cabinet through the first passage opening 1. Goods in the side single cabinet can enter the middle single cabinet through the first passage opening 1, and goods in the middle single cabinet can enter the other side single cabinet through the first passage opening 1.

[0088] Single cabinets with a cone structure can also be combined into a sphere shape, as shown in FIG. 19. In FIG. 19, adjacent single cabinets are attached to each other by a respective side plate. The two side plates attached to each other are each provided with the first passage opening 1. The first passage opening 1 is configured to communicate two adjacent single cabinets.

Third Embodiment

[0089] The combined cabinet may also include upper row cabinets 10 and lower row cabinets 11. The upper row cabinets 10 are a row of single cabinets on an upper layer, and the lower row cabinets 11 are a row of single cabinets on a lower layer, as shown in FIG. 21. In FIG. 21, one single cabinet of the upper row cabinets 10 is attached to one single cabinet of the lower row cabinets 11. The two attached single cabinets are communicated with each other through the first passage opening 1. In this way, the upper row cabinets 10 and the lower row cabinets 11 can communicate with each other through the passage opening 1. In addition, the cabinet door of the upper row cabinets 10 is located outside the visual range of the cabinet door of the lower row cabinets 11, and vice versa. With this arrangement, customers can stand in front of the upper row cabinets 10 or the lower row cabinets 11 to select goods, no crowding will occur, and the privacy of customers can be protected.

[0090] Furthermore, multiple sets of upper row cabinets 10 are provided. The cabinet door of each set of upper row cabinets 10 is located outside the visible range of other sets of upper row cabinets 10. In this way, even if customers all buy goods from the upper row cabinets 10, there may be no crowding and privacy leakage between them.

[0091] Furthermore, multiple sets of lower row cabinets 11 are provided. The cabinet door of each set of lower row cabinets 11 is located outside the visible range of other sets of lower row cabinets 11. In this way, even if customers all buy goods from the lower row cabinets 11, there may be no crowding and privacy leakage between them.

Fourth Embodiment

[0092] The combined cabinet may also be assembled into a regular or irregular structure from polyhedral single cabinets. Specifically, the combined cabinet may be gravel-shaped. The gravel-shaped combined cabinet is composed of gravel-shaped single cabinets. Referring to FIG. 20, in FIG. 20, three single cabinets are combined into a gravel-shaped combined cabinet. All three single cabinets are irregular octahedrons. In this specification, there is no specific limitation on the gravel-shaped single cabinet. As long as it is a structure similar to gravel, it falls into the scope of protection of this specification. In FIG. 20, two adjacent single cabinets are attached to each other through their respective side plates. The two side plates which are attached to each other are each provided with the first passage opening 1 for goods to pass through. Thus, the three gravel-shaped single cabinets are communicated with each other.

[0093] Furthermore, the single cabinets can be connected by bolts or by clamping. In this specification, there is no specific limitation on the connection method between single cabinets. As long as the connection method can connect the single cabinets into a whole combined cabinet, it falls into the scope of protection of this specification.

[0094] Finally, to be further noted, the term “include”, “comprise” or any variant thereof is intended to encompass nonexclusive inclusion so that a process, method, article or device including a series of elements includes not only those elements but also other elements which have been not listed definitely or an element(s) inherent to the process, method, article or device.
