DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Technical solutions in the embodiments will be described below clearly and completely in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative, and in no way serves as any limitation to the present disclosure and its application or use. Based on the embodiments in the present disclosure, all of other embodiments obtained by a person of ordinary skill in the art without creative work should fall into the protection scope of the present disclosure.

[0024] Unless specifically stated otherwise, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure. Furthermore, it should be understood that, for ease of description, the sizes of various parts shown in the drawings are not drawn in accordance with actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the related art may be not discussed in detail, but where appropriate, the technologies, methods, and device should be regarded as part of the specification as granted. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of an exemplary embodiment may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0025] For ease of description, spatially relative terms such as “above . . . ”, “over . . . ”, “on an upper surface of . . . ” and “upper” may be used here to describe spatial positional relationship between one device or feature and other devices or features as shown in the figures. It should be understood that a spatially relative term is intended to encompass different orientations in use or operation other than the orientation of a device described in a figure. For example, if the device in the figure is inverted, then the device described as “above other devices or structures” or “over other devices or structures” will be positioned “below other devices or structures” or “under other devices or structures”. Thus, the exemplary term “above . . . ” may include both orientations of “above . . . ” and “below . . . ”. The device may also be positioned in other different ways (rotated by 90 degrees or in other orientations), and the relative spatial description used here is explained accordingly.

[0026] As shown in FIGS. 1 and 2, an unmanned vehicle chassis 1 of an embodiment of the present disclosure includes at least two chassis units 11. The at least two chassis units 11 are spliced to form the unmanned vehicle chassis 1. The unmanned vehicle chassis of the embodiment of the present disclosure is formed by splicing at least two chassis units, so unmanned vehicle chassis of different sizes can be formed by splicing different numbers of chassis units to carry cargo boxes of different sizes, without the need to specially design and develop different chassis for cargo boxes of different sizes, thereby reducing the research and development cost.

[0027] Specifically, in this embodiment, as shown in FIG. 1, the unmanned vehicle chassis 1 includes at least two identical chassis units 11. The chassis units 11 spliced to form the unmanned vehicle chassis 1 have same structures and sizes. Therefore, only one type of chassis unit needs to be developed during research and development, which greatly reduces the research and development cost. In the actual manufacturing process, it needs to design, according to the sizes of different cargo boxes, a chassis unit of a smallest size that can be spliced, to meet the requirement of carrying cargo boxes of different sizes.

[0028] In an embodiment not shown in the drawings, the unmanned vehicle chassis may also include at least two different chassis units. For example, three different types of chassis units may be provided, and then chassis of different sizes may also be formed by selecting different combinations from the three different types of chassis units and splicing the same.

[0029] Preferably, as shown in FIG. 1, the at least two chassis units 11 of this embodiment are spliced in a horizontal direction.

[0030] As shown in FIG. 2, the chassis unit 11 includes a chassis unit body 111 and wheels 113 provided at the underside of the chassis unit body 111. In this embodiment, as the underside of the chassis unit body 111 of each chassis unit 11 is provided with wheels 113, each chassis unit 11 can walk independently, thereby improving the adaptability of unmanned vehicle chassis formed by splicing a plurality of chassis units 11.

[0031] To ensure that chassis unit bodies 111 can be connected more tightly to form a structurally stable chassis, the chassis unit body 111 of this embodiment has connecting surfaces for connection with adjacent other chassis unit bodies. The chassis unit 11 further includes connecting portions provided on the connecting surfaces of the chassis unit body 111, and the connecting portions are configured to connect adjacent two chassis unit bodies 111.

[0032] Specifically, as shown in FIG. 2, the connecting portions of this embodiment include magnetic bodies 112.

[0033] Moreover, the connecting surfaces of the chassis unit body 111 of this embodiment include protrusions located at two ends respectively. The magnetic bodies 112 are attached to the protrusions. As shown in FIG. 2, a right side surface (in a left-right direction shown in the figure) of the chassis unit body 111 is provided with protrusions on both front and rear ends, and magnetic bodies 112 are attached to the protrusions. The design of the two connecting parts is beneficial to ensuring tight connection between the chassis unit body 111 and adjacent other chassis unit bodies 111, and avoiding detachment of the vehicle chassis during operation. This configuration is also beneficial to avoiding the problem of non-tight connection or misalignment of the magnetic bodies caused by failure to fit adjacent two connecting surfaces to each other when a process of manufacturing the chassis unit body 111 is not up to standard.

[0034] The magnetic body 12 of this embodiment may be a strong magnet or an electromagnet. In the case where the magnetic body is an electromagnet, for example, electromagnets may be provided on each side of the chassis unit body 111 and only the electromagnets provided on the connecting surfaces are controlled to be electrified and function, to avoid interference with the normal operation of the chassis caused by electromagnetic interaction with other irrelevant mechanisms on the road due to functioning of the electromagnets provided on non-connecting surfaces. For example, the electromagnets on lateral sides of the chassis unit bodies 111 in FIG. 1 that are located on outer sides of the unmanned vehicle chassis 1 and not connected to other chassis unit bodies may be configured not to be electrified.

[0035] The chassis unit body 111 of this embodiment is a square cavity structure. The square cavity structure has an opening to facilitate a working person placing and inspecting components placed in the square cavity structure.

[0036] Four wheels 113 are provided at the underside of the chassis unit body 111 of this embodiment.

[0037] Each chassis unit 11 of this embodiment can walk independently, and thus to enable the chassis units 11 to move synchronously, the unmanned vehicle chassis 1 of this embodiment includes a controller, which is coupled with the at least two chassis units 11 to control the at least two chassis units 11 to move synchronously.

[0038] The chassis unit 11 of this embodiment includes a communication module and a control module. The communication module receives a control signal from the controller and transmits the signal to the control module. Moreover, the communication module may also transmit an operating status of the chassis unit 11 to the controller. The communication module of each chassis unit may exchange information with the controller in a wireless transmission manner.

[0039] The chassis unit 11 includes wheels 113, a driving motor configured to drive the wheels 113 to travel, and a steering motor configured to control the steering of the wheels 113, and the control module is configured to control operation of the driving motor and the steering motor. Providing the driving motor and the steering motor can implement the movement control of the chassis unit 11 in any direction by the controller.

[0040] Preferably, the chassis unit of this embodiment further includes a battery power supply system to be responsible for power supply of the chassis unit itself.

[0041] An embodiment of the present disclosure further provides an unmanned vehicle. The unmanned vehicle includes the unmanned vehicle chassis described in the above embodiment.

[0042] Preferably, the unmanned vehicle includes a sensor assembly configured to monitor the surrounding environment and a controller, the controller being configured to receive monitoring information sent by the sensor assembly and control movement of the unmanned vehicle chassis according to the monitoring information.

[0043] The unmanned vehicle further includes a cargo box provided on the unmanned vehicle chassis, and the unmanned vehicle chassis formed by splicing at least two chassis units is adapted to the cargo box. The adaptation of the unmanned vehicle chassis to the cargo box here may be size adaptation or shape adaptation.

[0044] The unmanned vehicle of this embodiment is an unmanned delivery vehicle.

[0045] Finally, it should be noted that the above embodiments are only used for describing rather than limiting the technical solutions of the present disclosure. Although the present disclosure is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they still can make modifications to the specific implementations in the present disclosure or make equivalent substitutions to part of technical features thereof; and such modifications and equivalent substitutions should be encompassed within the scope of the technical solutions sought for protection in the present disclosure so long as they do not depart from the spirit of the technical solutions of the present disclosure.
