[0026] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0027] Please refer to the attached Figure 1-10The present invention provides a solar box cover 200 for covering the box body 100 of a solar electric vehicle. The solar box cover 200 includes a cover plate 210, a carrier plate 230, and a solar cell panel 220. The cover plate 210 and the carrier plate 230 are connected and clamp the solar cell panel 220. The clamping and fixing of the solar cell panel 220 by the cover plate 210 and the carrier plate 230 can avoid the need for connecting holes or other connecting parts on the solar cell panel 220. A first opening 2111 is provided in the middle of the cover plate 210 to expose the lighting surface of the solar panel 220. A liquid accumulation chamber 2321 is recessed on the side of the carrier plate 230 close to the solar panel 220. The carrier plate 230 includes a supporting portion 2312 for supporting the solar panel 220. The supporting portion 2312 is annular and is located on the outer periphery of the liquid accumulation chamber 2321. An annular filling member is provided between the supporting portion 2312 and the solar panel 220. The filling member is provided with a first partition notch 237, wherein the filling member expands when in contact with water and shrinks after dehydration. By providing the above-mentioned filling piece, the filling piece not only guides the infiltrated rainwater into the liquid accumulation chamber 2321 through the first partition notch 237 to prevent rainwater from flowing into electrical components such as the controller installed on the back of the solar panel 220, but the filling piece can also absorb part of the infiltrated rainwater and expand to apply an upward thrust to the solar panel 220 to reduce the gap between the cover 210 and the solar panel 220, thereby reducing the amount of rainwater infiltration. At the same time, the filling piece shrinks after dehydration to restore the gap between the cover 210 and the solar panel 220 to form a top heat dissipation gap, thereby achieving a balance between waterproof performance and heat dissipation performance of the solar compartment cover 200.

[0028] The filling piece may be, but is not limited to, a water-swellable polyurethane sealing strip or the like.

[0029] In some embodiments of the present application, there are multiple first partition notch portions 237, and the portion of the filler located between two adjacent first partition notch portions 237 is a filling ring segment 235. The side of the supporting portion 2312 close to the solar cell panel 220 is provided with multiple protrusions 236 corresponding one-to-one to the multiple filling ring segments 235. The protrusion 236 is an annular structure, and the filling ring segment 235 fills the inner cavity set in the protrusion 236, wherein the protrusion 236 is provided with a second partition notch portion.

[0030] In this embodiment, part of the infiltrated rainwater flows into the liquid accumulation chamber 2321 through the first spacing notch, and part of it flows into the raised portion 236 through the second spacing notch and is absorbed by the filling ring segment 235. After absorbing water, the filling ring segment 235 expands toward the solar panel 220 under the constraint of the raised portion 236, so as to increase the thrust of the filling member on the solar panel 220, which helps to reduce the gap between the cover plate 210 and the solar panel 220 on rainy days, thereby reducing the amount of rainwater infiltration and improving the waterproof and moisture-proof protection of solar component accessories such as the controller.

[0031] The first spacing gap portion is located between two adjacent protrusions 236 .

[0032] There may be multiple second spacing notches and the second spacing notches may be located at least on a side of the protrusion 236 close to the fluid accumulation cavity 2321 and a side of the protrusion 236 away from the fluid accumulation cavity 2321 .

[0033] In some embodiments of the present application, the cover plate 210 forms a limiting groove, which is located on the side of the first opening 2111 close to the carrier plate 230. The solar cell panel 220 is located in the limiting groove to horizontally limit the solar cell panel 220, thereby facilitating the precise installation of the solar cell panel 220.

[0034] Among them, a side gap is formed between the solar cell panel 220 and the groove wall of the limiting groove, which not only facilitates the rainwater that penetrates from between the cover plate 210 and the solar cell panel 220 to flow quickly to the liquid accumulation chamber 2321, but also the top heat dissipation gap, the side gap, the first spacing notch and the liquid accumulation chamber 2321 together form a heat dissipation channel.

[0035] The cover plate 210 includes a top plate portion 211 and circumferential side plates 213. The circumferential side plates 213 are located below the top plate portion 211 and are arranged around the edges of the top plate portion 211. The circumferential side plates 213 are located around the carrier plate 230. A retaining ring 212 is provided on the side of the top plate portion 211 closest to the solar panel, and the retaining ring 212 is arranged to form a retaining groove.

[0036] In some embodiments of the present application, the cover plate 210 is detachably connected to the vehicle body 100 so that the vehicle body 100 and the solar compartment cover 200 can be disassembled to facilitate the subsequent maintenance and replacement of the solar compartment cover 200.

[0037] In some embodiments of the present application, the cover plate 210 is connected to the vehicle body 100 via a buckle structure, so that the disassembly operation between the vehicle body 100 and the solar compartment cover 200 is simple and convenient.

[0038] The buckle structure includes a hook portion 320 and a locking portion 310. The locking portion 310 has a buckle 311 and cooperates with the hook portion 320 through the buckle 311. The hook portion 320 is provided on the cover plate 210, and the buckle 311 is provided on the vehicle body 100, so that personnel can easily lock and unlock the buckle structure. Preferably, a plug 214 is provided on the side of the top plate 211 close to the carrier plate 230. The plug 214 is located on the outer periphery of the carrier plate 230 and is fixedly connected to both the top plate 211 and the circumferential side plate 213. The hook portion 320 is provided on the side of the plug 214 close to the carrier plate 230. The vehicle body 100 is provided with an insert block 120, and the insert block 120 is provided with the locking portion 310. The insert block 120 is inserted into the plug 214, and the buckle 311 of the locking portion 310 cooperates with the hook portion 320.

[0039] In some embodiments of the present application, the carrier plate 230 is provided with a guide port 2331, which is connected to the liquid accumulation chamber 2321. A drainage channel is provided at the covering joint of the cover plate 210 and the vehicle body 100. The top of the drainage channel has a second opening, and the guide port 2331 is located above the second opening, so that the liquid in the liquid accumulation chamber 2321 can be discharged to the drainage channel through the guide port 2331 and discharged to the outside of the vehicle through the drainage channel.

[0040] The carrier plate 230 includes an annular edge portion 231 and a liquid accumulation portion 232 located inside the edge portion 231. The liquid accumulation portion 232 is recessed relative to the edge portion 231 to form a liquid accumulation chamber 2321. The edge portion 231 includes an annular connecting portion 2311 and a supporting portion 2312. The connecting portion 2311 is located on the outer periphery of the supporting portion 2312. The connecting portion 2311 and the limiting ring 212 are arranged opposite each other in the vertical direction and are fixedly connected by threaded fasteners. A guide tube 233 is provided on one side of the liquid accumulation portion 232. The first end of the guide tube 233 extends into the liquid accumulation chamber 2321, and the top of the guide tube 233 extends to the edge portion 231 and is open. The second end of the guide tube 233 is formed with a guide port 2331.

[0041] In some embodiments of the present application, an annular retaining member 110 is protruding from the top of the vehicle body 100, and the cover plate 210 includes an annular overlapping portion, which is specifically located on the peripheral side plate portion of the cover plate 210. The overlapping portion is sleeved around the outer periphery of the retaining member 110 and overlaps the top of the vehicle body 100, with a drainage channel formed between the overlapping portion and the retaining member 110. The drainage channel is located outside the retaining member 110 and can prevent liquid in the drainage channel from flowing into the vehicle compartment.

[0042] When the overlapping portion overlaps the top of the vehicle body 100 , the insert block 120 is inserted into the insert tube 214 .

[0043] When the overlapping portion overlaps with the top of the vehicle body 100 , an assembly gap is provided between the overlapping portion and the top surface of the vehicle body 100 , and the liquid in the drainage channel is discharged to the outside of the vehicle through the assembly gap.

[0044] Preferably, the top surface of the vehicle body 100 has an annular overlapping surface 101, the limiting member 110 is located on the inner side of the overlapping surface 101, and the overlapping portion includes a first plate segment 2131 and a second plate segment 2132 connected to each other.
