[0002] In energy storage devices, the box body structure is a frequently used structure. For example, electric control boxes, distribution boxes, and battery boxes all have box bodies. Most of the existing box body structures include a main box body and a cover body. The cover body is buckled on the main box body, and a sealing ring is installed between the main box body and the cover body to achieve the functions of waterproofing and dustproofing. The surface area of the cover body in this structure is relatively large. In order to prevent it from deforming, a relatively large number of reinforcing beams need to be welded on the cover body, which will increase the weight of the entire box body structure. And when the structure inside the main box body needs to be repaired or replaced, the entire cover body needs to be removed, which is not convenient for maintenance. If a certain part of the cover body has a problem, only the entire cover body can be replaced, reducing the service life of the box body structure. Summary of the Utility Model

The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0030] The present utility model discloses a box body structure, which can be used as the outer shell of a distribution box, can also be used as the outer shell of an electric control box, can also be used as the outer shell of an energy storage power supply, and can also be used as other equipment that requires a sealed box body.

[0031] Such as Figures 1-4As shown in the figure, the box body structure of the present utility model includes a main box body 100, a panel assembly 200, and a panel seal 400. One end of the main box body 100 is open. The panel assembly 200 is connected to the open end of the accommodating cavity of the main box body 100. The panel assembly 200 includes two sealing panels 210. Each sealing panel 210 is individually connected to the main box body 100. There is an overlapping area between two adjacent sealing panels 210. A splicing seal 300 is arranged in the overlapping area to achieve the sealing splicing of two adjacent sealing panels 210. The panel seal 400 is clamped between the panel assembly 200 and the open end of the main box body 100.

[0032] First of all, it should be noted that in the embodiments of the present utility model, the number of sealing panels 210 included in the panel assembly 200 can be two, three or even more according to actual needs. For the convenience of description, the following description will be made with two sealing panels 210. In the drawings, both of the two sealing panels 210 are rectangular plates. However, in other embodiments of the present utility model, the sealing panel 210 can also be formed into a triangular, circular or other shaped plate-like structure, which can be selected according to actual needs.

[0033] It can be understood that since the panel assembly 200 for sealing the main box body 100 in this embodiment includes two sealing panels 210, compared with the complete cover structure in the prior art, the surface area of the sealing panel 210 in this embodiment is smaller, the anti-deformation ability is larger, the use of reinforcing beams is reduced, the weight of the sealing panel 210 is reduced, and thus the weight of the entire box body structure is reduced. Since the two sealing panels 210 are individually connected to the main box body 100, when the components inside the main box body 100 need to be repaired or replaced, only the sealing panel 210 corresponding to the component needs to be removed from the main box body 100, and there is no need to remove the entire panel assembly 200, which is convenient for the repair and replacement of the components inside the main box body 100. And when the panel assembly 200 is damaged, only the corresponding sealing panel 210 needs to be replaced, and there is no need to replace the entire panel assembly 200, which is beneficial to extending the service life of the panel assembly 200.

[0034] It should be added that the splicing seal 300 can ensure the sealing performance at the butt joint position of the two sealing panels 210, so as to ensure the waterproof and dustproof performance of the panel assembly 200. The panel seal 400 between the panel assembly 200 and the main box body 100 can ensure the waterproof and dustproof performance of the entire box body structure.

[0035] Optionally, the splicing seal 300 and the panel seal 400 are made of high-performance waterproof materials (such as silicone, polyurethane, etc.). These materials have good weather resistance, aging resistance and bonding strength, so as to ensure that the entire box body structure has good waterproof and dustproof performance.

[0036] ReferenceFigures 4-6 As shown, the sealing panel 210 is connected to the main box body 100 by fasteners 500. It can be understood that by using the fasteners 500 to connect the sealing panel 210 and the main box body 100, the connection stability and connection tightness between the two can be improved, thereby ensuring that the entire box body structure has good waterproof and dustproof performance.

[0037] Optionally, a fixed edge 110 is provided at the open end of the main box body 100, and the fastener 500 passes through the sealing panel 210 and is connected to the fixed edge 110. It can be understood that the fastener 500 passing through the sealing panel 210 and being fixed on the fixed edge 110 can ensure the connection stability of the fastener 500, and the fact that the sealing panel 210 abuts against the fixed edge 110 is also beneficial to improving the tightness of the connection position between the sealing panel 210 and the main box body 100. Further optionally, a sealing layer is provided between the sealing panel 210 and the fixed edge 110. Thus, while ensuring the connection stability between the sealing panel 210 and the fixed edge 110, the connection tightness between the two can also be improved.

[0038] Further optionally, the fixed edge 110 has a plurality of riveting posts 111 arranged at intervals along its contour line. Each riveting post 111 is provided with a threaded hole, and the sealing panel 210 is provided with a mating hole corresponding to the threaded hole. The fastener 500 includes a fastening screw, and the fastening screw passes through the mating hole and is connected to the threaded hole. It can be understood that providing the riveting posts 111 on the fixed edge 110, compared with directly opening threaded holes on the fixed edge 110, after fixing the sealing panel 210 to the fixed edge 110 using the fastening screw, has better stability and tightness, thereby improving the connection stability and connection tightness between the sealing panel 210 and the fixed edge 110. It should be added that the model of the fastening screw can be selected according to actual needs. In this embodiment, the fastening screw is a three-in-one screw (referring to a three-component assembly composed of one screw, one spring washer, and one flat washer). In other embodiments of the present utility model, the fastener 500 can also be other fastening structures such as pins and rivets, and is not limited to the fastening screw in this embodiment.

[0039] In some alternative embodiments, the sealing panel 210 is snap-connected to the main box body 100. It can be understood that the sealing panel 210 is connected to the main box body 100 through a snap structure. On the one hand, it facilitates the installation of the sealing panel 210 onto the main box body 100, making it convenient for the operator to install, disassemble, and replace the sealing panel 210. On the other hand, it can ensure the connection stability between the sealing panel 210 and the main box body 100, and avoid the phenomenon of the sealing panel 210 falling off from the main box body 100.

[0040] Reference Figure 4 and Figure 8As shown, a plugging groove 410 is provided on the surface of the panel seal 400 facing away from the panel assembly 200, and a plugging convex edge 120 is provided in the open end of the main box body 100. The plugging convex edge 120 can be plugged into the plugging groove 410. It can be understood that during the actual assembly process, the plugging groove 410 of the panel seal 400 is fitted onto the plugging convex edge 120, and then the panel assembly 200 is fixed to the main box body 100. When installing the panel assembly 200, the panel seal 400 must be fixed to the main box body 100, which is conducive to the panel assembly 200 squeezing the panel seal 400 when installing the panel assembly 200, so as to make the seal between the panel assembly 200 and the main box body 100 better.

[0041] Optionally, a stopping portion 112 is further provided on the plugging convex edge 120, and the surface of the panel seal 400 facing away from the panel assembly 200 can be stopped against the stopping portion 112. It can be understood that the added stopping portion 112 can make the panel assembly 200 better squeeze the panel seal 400 when installing the panel assembly 200, because both sides of the panel seal 400 are respectively stopped against the stopping portion 112 and the panel assembly 200, which is convenient for the panel seal 400 to deform, so as to make the seal between the panel assembly 200 and the main box body 100 better.

[0042] In some alternative embodiments, a plugging convex edge 120 is provided on the surface of the panel seal 400 facing away from the panel assembly 200, and a plugging groove 410 is provided in the open end of the main box body 100. In the actual design structure, the positions of the plugging convex edge 120 and the plugging groove 410 can be set according to actual needs.

[0043] Optionally, referring to Figure 8 As shown, the surface of the panel seal 400 facing the panel assembly 200 has a first sealing protrusion 420 extending along its outer contour. It can be understood that the first sealing protrusion 420 of the panel seal 400 contacts the panel assembly 200. The surface area of the first sealing protrusion 420 is small, and the pressure exerted by the panel assembly 200 on the first sealing protrusion 420 is greater, making the deformation amount of the panel seal 400 greater, so as to make the seal between the panel assembly 200 and the main box body 100 better. Further optionally, the first sealing protrusions 420 are multiple and arranged at intervals. In addition, in an alternative embodiment, the first sealing protrusion 420 is provided on the side wall of the panel seal 400 facing the main box body 100; in another alternative embodiment, the first sealing protrusions 420 are simultaneously provided on two opposite side walls of the panel seal 400. In the embodiments of the present invention, the position, number, size and cross-sectional shape of the first sealing protrusion 420 can be selected according to actual needs.

[0044] Optionally, referring to Figure 8As shown, the panel seal 400 is also provided with a first through hole 430 penetrating along its length direction. The added first through hole 430 facilitates the deformation of the panel seal 400 under the extrusion of the panel assembly 200, so that there is better sealing performance between the panel assembly 200 and the main box body 100. In the embodiment of the present invention, the cross-sectional shape and size of the first through hole 430 can be selected according to actual needs.

[0045] Refer to Figure 2 and Figure 3 As shown, a drainage structure is provided on the bottom of the panel assembly 200 and / or the surface of the panel assembly 200 facing away from the main box body 100. It can be understood that the drainage structure can be a drainage hole 214 formed on the bottom wall of the lower sealing panel 210, or a drainage groove 213 formed on the lower sealing panel 210, and the drainage groove 213 also has a notch. The added drainage structure can ensure that the liquid that may accumulate on the panel assembly 200 is discharged from the box body structure, thereby improving the waterproof performance of the box body structure.

[0046] Refer to Figures 4-6 As shown, among two adjacent sealing panels 210, a protruding portion 211 protrudes from one side of the sealing panel 210 facing away from the main box body 100, and a recessed portion 212 is provided on the side of the other sealing panel 210 facing away from the main box body 100. The protruding portion 211 is fitted into the recessed portion 212, and the protruding portion 211 can press the splicing seal 300 against the side wall of the recessed portion 212. It can be understood that during the actual installation process, first install the sealing panel 210 with the recessed portion 212 onto the main box body 100 (as Figure 5 shown). During the installation process, install the splicing seal 300 onto the recessed portion 212, and then install the sealing panel 210 with the protruding portion 211 onto the main box body 100. During the installation process, press the protruding portion 211 against the splicing seal 300. When the installation of the sealing panel 210 with the protruding portion 211 is completed, the splicing seal 300 deforms, so that the joint of the two sealing panels 210 has good waterproof and dustproof performance.

[0047] Optionally, refer to Figure 7As shown, one side of the splicing seal 300 facing the protruding portion 211 is provided with a second sealing protrusion 310 extending along its length direction. In an alternative embodiment, one side of the splicing seal 300 facing the side wall of the recessed portion 212 is provided with a second sealing protrusion 310. It can be understood that the second sealing protrusion 310 of the splicing seal 300 contacts the protruding portion 211. The surface area of the second sealing protrusion 310 is small, and the pressure exerted by the protruding portion 211 on the second sealing protrusion 310 is greater, so that the deformation amount of the splicing seal 300 is greater, thereby making the sealing performance between the two sealing panels 210 better. Further optionally, the second sealing protrusions 310 are multiple and arranged at intervals. In another alternative embodiment, the second sealing protrusions 310 are provided on both opposite side walls of the splicing seal 300. In the embodiment of the present utility model, the position, quantity, size and cross-sectional shape of the second sealing protrusion 310 can all be selected according to actual needs.

[0048] Optionally, the splicing seal 300 is further provided with a second through hole 320 penetrating along its length direction. The added second through hole 320 facilitates the deformation of the splicing seal 300 under the extrusion of the protruding portion 211, thereby making the sealing performance between the two sealing panels 210 better. In the embodiment of the present utility model, the cross-sectional shape and size of the second through hole 320 can be selected according to actual needs.

[0049] The advantages of the box body structure of the present utility model are as follows:

[0050] First: The sealing panels 210 with various different ratios can be designed according to actual needs to meet different usage requirements;

[0051] Second: The anti-seepage effect is good.
