[0027] In the present disclosure, addressing the common issues of existing canopies, such as complex structures, high costs, cumbersome installation, and susceptibility to damage and leakage over prolonged use, which not only increase user inconvenience and expenses but may also lead to rainwater erosion of building walls and floors, a leak-proof canopy is provided. Through the synergistic structure of the support assembly and the water diversion assembly, the support assembly forms a stable, deformation-resistant foundational support by leveraging the symmetrical support of the bottom frame, the grid-like load-bearing of the top frame, and the triangular support system of the side frame. The water diversion assembly, relying on the color steel tile top plate with an arc-shaped groove design and the water diversion plate integrated with a water diversion channel, constructs a dual drainage and leak-proof structure, effectively resolving the technical shortcomings of existing canopies. Below, the specific implementation of the leak-proof canopy of the present disclosure will be described in detail with reference to the accompanying drawings.

[0028] As shown in FIGS. 1 and 2, the present disclosure provides a leak-proof canopy 10, including a support assembly 100 and a water diversion assembly 200. The support assembly 100 includes a bottom frame 110, a top frame 120 and a side frame 130. The bottom frame 110, the top frame 120 and the side frame 130 are configured as several elongated support rods, preferably square-section support rods in this disclosure. In other embodiments of the present disclosure, the shapes of the bottom frame 110, the top frame 120 and the side frame 130 are not limited to square; they can also be cylindrical support rods, triangular support rods, or rounded rectangular column support rods, or any other shape desired by the user. The support rods are stably and fixedly connected to each other through bolt connections. It should be noted that bolt connections between adjacent support rods are not the only option; in other embodiments, pin connections, snap connections, welding, or other methods may also be used to achieve stability.

[0029] Referring to FIGS. 1 and 2, the bottom frame 110 is arranged in several sets, preferably two sets of support rods in this disclosure, symmetrically distributed along the bottom edge of the canopy to cooperate with the installation surface (such as the ground or the side of a building wall). This provides a foundational support base for the entire leak-proof canopy 10, enabling the support assembly 100 to stand stably and ensuring the overall structural stability of the canopy. It also offers reliable bottom support conditions for functions such as rain shielding and water diversion at the top and sides. The connection between the bottom frames 110, as well as the connection between them and the side frame 130 are achieved through the aforementioned connection methods (such as bolt connection or pin connection), ensuring the robustness of the bottom structure. The top frame 120 is positioned at the top of the support assembly 100, featuring a contour structure that matches the bottom frame 110. It consists of several elongated support rods arranged at preset intervals to form the top load-bearing framework of the canopy. The top frame 120 is used to carry the water diversion assembly 200 of the canopy. Simultaneously, the top frame 120 and the upper end of the side frame 130 are fixed by the aforementioned stable connection methods, such as bolt connection or snap connection, ensuring the top structure and side supports form an integrated stress system. This prevents the top frame from shifting or detaching due to external forces (e.g., strong winds or snow accumulation). The side frame 130 serves as a transitional support structure connecting the bottom frame 110 and the top frame 120, distributed circumferentially along the sides of the canopy to form several sets of vertical support units. The lower end of the side frame 130 is fixedly connected to the end of the bottom frame 110 through bolts or welding, while the upper end is correspondingly connected to the end of the top frame 120, forming a triangular support system of "bottom-side-top." This significantly enhances the anti-deformation capability and stability of the entire support assembly 100.

[0030] In other embodiments (not shown), detachable counterweight connection bases are provided at the four corners of the bottom frame and at suitable intermediate positions along the bottom. The counterweights are detachably fixed to the connection bases through bolts, allowing the number and mass of the counterweights to be adjusted based on the wind load and usage requirements of the actual installation site. This enhances the stability of the canopy under harsh weather conditions such as strong winds and reduces the risk of overturning. At the same time, anti-slip rubber pads are installed at the contact points between the bottom frame and the installation surface. These pads are fixed to the bottom frame through adhesion or mechanical snaps, significantly increasing the friction between the bottom and the ground. Combined with the counterweights, they improve the canopys resistance to pitching and translation, facilitating long-term stable use in outdoor or open environments and enabling easy on-site maintenance and replacement.

[0031] Specifically, as shown in FIG. 2, the top frame 120 includes a main frame rod 121 and several auxiliary support bars 122. The main frame rod 121 extends in the same direction as the bottom frame 110, forming the outer skeleton of the top structure. The auxiliary support bars 122 are spaced parallel to each other along the length of the main frame rod 121, perpendicular to the main frame rod 121, forming a grid-like support structure together with the main frame rod 121. This not only strengthens the in-plane rigidity of the top but also provides uniform installation pivots for the water diversion assembly 200 (see FIG. 1). When the ends of the support bars 122 extend to the edge of the top frame, they are fixedly connected to the top of the side frame 130 through bolts or snap locks. This ensures that top loads (such as rainwater impact or snow accumulation) are directly transferred through the auxiliary support bars 122 to the side frame 130, which then disperses them to the bottom frame 110. By preventing load concentration on the main frame rod 121, this design enhances the tightness of the connection between the top frame 120 and the side frame 130 while improving the overall deformation resistance of the support assembly 100 through multi-node load distribution, providing reliable structural support for the canopys leak-proof function.

[0032] As shown in FIG. 2, the side frame 130 is equipped with several reinforcing struts 131, which are inclined to form an auxiliary connection configuration and are distributed and fixed on the side frame 130. One end of each reinforcing strut 131 is securely fastened to the side frame 130 through stable connection methods such as bolt connection or welding. The reinforcing struts 131, together with the side frame 130 and the adjacent bottom frame 110, form a triangular support structure. This effectively disperses external forces (such as wind and rain loads) acting on the side frame 130, preventing bending or deformation due to localized stress concentration. It further enhances the structural strength and anti-deformation capability of the side frame 130 and even the entire support assembly 100, providing more reliable lateral support for the stable use of the leak-proof canopy 10.

[0033] In other embodiments (not shown), to further improve the strength of the side frame 130, additional diagonally arranged reinforcing struts can be added between adjacent vertical support rods. These diagonal reinforcing struts, together with the vertical support rods, form a plurality of continuous triangular stable structures, significantly enhancing the overall load-bearing capacity and anti-deformation capability of the side frame. Additionally, the side frame 130 can be designed as an adjustable structure, for example, by adjusting the length of the support rods through methods like sleeve bolt locking, to accommodate different eave heights or installation scenarios, greatly increasing the versatility of the canopy.

[0034] Please also refer to FIGS. 2, 3, 4, 5, and 6. The water diversion assembly 200 includes several top plates 210 and water diversion plates 220. The top plate 210 is laid above the top frame 120, and its shape is preferably a curved plate with grooves. The grooves of the curved plate extend along the preset direction of rainwater flow, leveraging the slope of the curved surface to guide rainwater to slide down smoothly while enhancing the rigidity of the top plate 210 through the groove structure. Additionally, it provides a more precise diversion channel for rainwater. The top plate 210 is securely connected to the support bar 122 of the top frame 120 through a bolt structure, ensuring a stable connection between the top plate 210 and the support assembly 100 to reliably bear rainwater loads. Specifically, the support bar 122 is equipped with a first installation hole 1221, while the top plate 210 has a bolt hole that matches the position and size of the first installation hole 1221. An external bolt passes through the bolt hole of the top plate 210 and the first installation hole 1221 in sequence, enabling the top plate 210 to be stably installed on the top frame 120. Adjacent top plates 210 are fixed together by single-sided adhesive foam waterproof strips, which seal the gaps between the top plates 210 to prevent rainwater leakage, significantly improving the rain shelters leak-proof performance. The material of the top plate 210 is preferably color steel tile, which not only offers excellent waterproofing and weather resistance but also enhances the rigidity of the plate surface through its profiled structure. Moreover, it facilitates the rapid flow of rainwater along the plate surface, laying the foundation for efficient drainage.

[0035] In other embodiments, the material of the top plate 210 is not limited to color steel tile. It can also be made of polymer composite panels (such as FRP daylight panels), aluminum alloy plates, galvanized steel plates, or wood/cement fiber boards with durable waterproof coatings. Among these, FRP daylight panels combine waterproofing and light-transmitting functions, making them suitable for scenarios requiring natural lighting. Aluminum alloy plates, with their excellent corrosion resistance and lightweight characteristics, can further extend the rain shelters service life and simplify the support structure.

[0036] In other embodiments (not shown), when two adjacent top plates 210 are butted together, in addition to using a single-sided adhesive foam waterproof strip for sealing, a dedicated sealing strip installation groove can be specifically designed at the butting edge of the top plate 210. During installation, a flexible sealing strip is first embedded into the groove, and then the butting edges of the two top plates 210 are brought together and pressed tightly. This dual-sealing design, combining "embedded sealing strips" with "surface waterproof strips," significantly enhances the sealing effect at the top plate joints, fundamentally preventing rainwater from seeping through the connection gap.

[0037] In other embodiments (not shown), a high-performance waterproof coating can be brushed or sprayed onto the surface of the top plate 210 and key connection areas of the canopy framework (such as around the bolt holes of the top plate or at joint fittings). This waterproof coating should exhibit excellent weather resistance, water resistance, and adhesion, effectively preventing rainwater penetration and capillary action, thereby providing supplementary reinforcement to the overall leak-proof performance of the canopy. Even after prolonged exposure to wind and sunlight, the coating maintains its performance, ensuring long-lasting waterproofing for the canopy.

[0038] As shown in FIGS. 5, 7, 8, and 9, the water diversion plate 220 is configured as an elongated trough-shaped structure and is fixedly installed onto the support bar 122 of the top frame 120 through a bolt structure. Specifically, the support bar 122 is provided with a second installation hole 1222, and the water diversion plate 220 has a corresponding bolt hole that matches the position and size of the second installation hole 1222. A bolt passes through the bolt hole of the water diversion plate 220 and the second installation hole 1222, thereby securely connecting the water diversion plate 220 to the top frame 120. The water diversion plate 220 also integrates a water diversion channel 221. During installation, the water diversion plate 220 is assembled between the top plate 210 and the support bar 122. The connection gap 211 formed after two adjacent top plates 210 are fixed with a waterproof strip is precisely positioned above the water diversion channel 221. Through this design, even if rainwater leaks through the connection gap 211 of adjacent top plates 210, it will directly fall into the water diversion channel 221 and be discharged outside the canopy along the channel. The water diversion plate 220 and the top plate 210 together form a dual drainage structure, effectively preventing rainwater from penetrating into the support assembly 100 or the area below the canopy.

[0039] In other embodiments (not shown), the support bar 122 of the top frame 120 is pre-punched or machined with positioning slots for the water diversion plate. During the installation of the water diversion plate 220, its edges can first be precisely inserted into the positioning slots for pre-alignment, followed by final fastening using bolts. This design makes the installation of the water diversion plate 220 more convenient, accurate, and secure, effectively preventing water leakage risks such as misalignment of the water diversion channel due to installation deviations. Additionally, all components of the top frame 120 can undergo anti-corrosion treatments, such as applying rust-proof primer and topcoat, to significantly extend its service life and avoid compromising the overall structural safety and leak-proof performance of the canopy due to frame corrosion.

[0040] In other embodiments (not shown), to further optimize drainage performance, the end of the water diversion plate 220 can be integrated or connected with a downward-sloping diversion spout. This design prevents rainwater from dripping at the end of the water diversion channel, which could erode the substructure or wet the wall surface. Furthermore, a plurality of diversion spouts can be connected through hoses to a centralized vertical downpipe, directing rainwater in an organized manner to the ground drainage system for neater and more efficient drainage management.

[0041] In summary, the present disclosure achieves the following technical effects: through the symmetrical distribution of the bottom frame 110 in the support assembly 100, the triangular support system formed by the side frame 130 with the bottom frame 110/top frame 120 ("bottom-side-top"), and the reinforcing strut 131 inclined on the side frame 130, external forces such as wind, rain, and snow accumulation are dispersed, avoiding localized stress concentration that could lead to bending deformation. This significantly enhances the overall structural stability and anti-deformation capability of the leak-proof canopy 10, solving the problem of existing canopies being prone to damage. The grid-like support structure of the main frame rod 121 and auxiliary support bar 122 in the top frame 120 evenly distributes top loads (rain impact, snow weight) to the side frame 130, preventing the top frame from shifting or detaching, thereby providing a stable load-bearing foundation for the water diversion assembly 200. The curved grooves in the top plate 210 of the water diversion assembly 200 and the single-sided adhesive foam waterproof strips between adjacent top plates reduce rainwater leakage at the joints. Combined with the waterproof and weather-resistant properties of the color steel tile material, a basic leak-proof guarantee is formed. Meanwhile, the cooperation between the water diversion channel 221 of the water diversion plate 220 and the top plate 210 ensures that even if rainwater leaks, it falls into the water diversion channel and is drained, forming a dual drainage and leak-proof structure that effectively prevents rainwater from penetrating the support assembly or the area below the canopy, solving the problems of rain leakage and building erosion. In the leak-proof canopy 10 provided by the present disclosure, all components are fixed through simple bolts or pin connections, simplifying the canopy structure, reducing custom components, lowering costs, and improving installation efficiency, thereby addressing the issues of complex structure, high cost, and cumbersome installation in existing canopies.

[0042] In the description of the present disclosure, it should be appreciated that directional terms such as "front, rear, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. In the absence of a contrary explanation, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present disclosure; the directional terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0043] For the convenience of description, spatial relative terms such as "on...", "above...", "on the upper surface of...", "upper" etc. may be used here to describe the spatial positional relationship of a device or feature with other devices or features as shown in the drawings. It should be appreciated that spatial relative terms are intended to encompass different orientations of the device in use or operation other than the orientation described in the drawings. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on other devices or structures" will subsequently be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here should be interpreted accordingly.

[0044] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning, and therefore should not be understood as limiting the scope of protection of the present disclosure.

[0045] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modifications, equivalent replacements, improvements etc. made within the spirit and principles of the present disclosure should be included within the scope of protection of the present disclosure.
