The end plate 4 of the battery box provided in the embodiment of the present application is detachably designed, and the end plate 4 can be opened to facilitate the disassembly, assembly or maintenance of the battery module 3. Among them, a sealing gasket a is arranged on the periphery of the take-in and take-out port. When the end plate 4 is connected to the main frame 1, the sealing gasket a is compressed to improve the sealing of the accommodating cavity.

[0062] In one possible embodiment, see Figure 2 and Figure 8 As shown, the battery box for convenient disassembly and assembly of the battery module includes two end plates 4, the frame plate 2 includes two first frame plates 21 and two second frame plates 22, the two first frame plates 21 are arranged on both sides of the main frame 1 along the first direction, the two second frame plates 22 are arranged on both sides of the main frame 1 along the second direction, two access ports are formed between the two first frame plates 21 and the two second frame plates 22, the two end plates 4 are detachably connected to both sides of the main frame 1 along the third direction, and the two access ports are closed respectively. Each battery module 3 is loaded into the accommodating cavity through the access ports on both sides.

[0063] It should be noted that each first frame plate 21 may be composed of two plates located in the same plane, such as Figure 8 The first frame plate 21 has a plate body removed.

[0064] In one possible embodiment, see Figure 2 , Figure 5 and Figure 8 As shown, the main frame 1 includes two first frames 11, the two first frames 11 are arranged at intervals, and the two first frames 11 are connected on both sides along the second direction by a set of support beams 12 (there are multiple sets of support beams in the figure, or there may be only the top and bottom two sets of support beams), the two first frame plates 21 are respectively connected to the two first frames 11, and the two second frame plates 22 are respectively connected to the sides of the two sets of support beams 12 away from the battery module, and the end plate 4 is fixed to the first frame 11 and / or the support beam 12 by fasteners (not shown). In this embodiment, the fasteners can be bolts for easy disassembly.

[0065] In one possible embodiment, see Figure 2As shown, the main frame 1 has an end column 111 located at one side of the access opening, and the end column 111 and / or the support beam 12 located at one side of the access opening are provided with fixing holes (not shown). The end plate 4 is provided with connecting holes around the edge, and a plurality of fasteners are respectively connected to corresponding fixing holes through a connecting hole.

[0066] The frame plate includes a plurality of inner frame plates 23, each of which is disposed in the accommodating cavity, each of which is spaced in sequence along the second direction, each of which extends along the third direction, and each of which divides the accommodating cavity into a plurality of sub-cavities. Each of the battery modules 3 is inserted into the corresponding sub-cavity through the access opening. Through the design of the inner frame plates 23, each of the battery modules 3 is stacked in layers and in an orderly manner.

[0067] In one possible embodiment, see Figure 5 As shown, a wear-resistant strip 231 a is connected to the supporting surface of each inner frame plate 23 , and the wear-resistant strip 231 a is extended along the third direction, and the battery module 3 is supported on the wear-resistant strip 231 a .

[0068] In this embodiment, wear-resistant strips 231a are provided on the inner frame plate 23. When the battery module 3 is loaded into the battery box, the bottom wall of the battery module 3 fits with the wear-resistant strips. The inner frame plate 23 may be a metal structure, and the surface is covered with a protective layer. In the process of loading the battery module 3 onto the inner frame plate 23, the battery module 3 is easy to damage the protective layer. In view of this, in an embodiment of the present application, wear-resistant strips 231a are provided on the support surface, and the wear-resistant strips 231a may be higher than the support surface of the inner frame plate 23. After the battery module 3 is loaded into the inner frame plate 23, it may directly contact the wear-resistant strips 231a and have a small gap with the protective layer, so as to avoid wear on the protective layer on the surface of the inner frame plate 23 during the process of disassembling and assembling the battery module 3. The wear-resistant strips may be made of engineering plastics. The wear-resistant strip 231a is extended along the third direction, that is, along the direction of loading or removing the battery module 3, so that the battery module 3 can be supported on the wear-resistant strip 231a during the process of sliding into or out of the battery box to avoid friction contact with the protective layer.

[0069] In a possible implementation, the battery box that facilitates disassembly and assembly of the battery module also includes a locking component 5, a first avoidance hole is provided on the first frame plate 21, and a locking hole 311 is provided on the battery module 3, and the locking component 5 can pass through the first avoidance hole and be inserted into the locking hole 311 to lock the battery module 3.

[0070] The locking component 5 can pass through the first avoidance hole from the outside to lock the battery module 3 located inside, thereby facilitating the assembly and fixation of the battery module 3 .

[0071] In one possible embodiment, see Figure 7 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, a module fixing beam 13 is arranged in the cavity, and the module fixing beam 13 can be fixed on the first frames 11 on both sides. The module fixing beam 13 has a beam body 131 and a limit plate 132 connected to the beam body 131, and a second avoidance hole is arranged on the limit plate 132. The locking component 5 passes through the first avoidance hole, the second avoidance hole and the locking hole 311 respectively.

[0072] Among them, a plurality of limiting plates 132 are arranged on the beam body 131, and each of the limiting plates 132 is arranged in sequence along the length direction of the module fixing beam 13. The battery module 3 includes a module body and a locking fitting portion 31 connected to the module body, and the locking fitting portion 31 is provided with the locking hole 311. When each battery module 3 is loaded into the cavity, the locking fitting portion 31 of the battery module 3 is located between two adjacent limiting plates 132, that is, a battery module 3 can be fixed between two adjacent limiting plates 132. The locking component 5 passes through the through hole and the second avoidance hole on each of the limiting plates 132 to lock multiple battery modules 3 at the same time.

[0073] See also Fig.11 and Fig.12 As shown, the locking fitting part 31 is provided with guiding inclined surfaces 312 on both sides along the length direction of the beam body 131, the width of the module body matches the distance between two adjacent limiting plates 132, and the distance between the two guiding inclined surfaces 312 and one end of the module body is smaller than the distance between two adjacent limiting plates 132. In the process of sliding the battery module 3 into the inner side of the inner frame plate 23, the two guiding inclined surfaces 312 play a guiding role, which is conducive to the locking fitting part 31 of the battery module 3 to slide smoothly into between the two limiting plates 132.

[0074] In a possible implementation, the module fixing beam 13 also includes a limiting beam 133 connected to the beam body 131, and the limiting beam 133 extends along the length direction of the beam body 131. When the battery module 3 is loaded into the accommodating cavity and abuts against the limiting beam 133, the first avoidance hole and the locking hole 311 are positioned relative to each other. The limiting beam 133 can limit the position where the battery module 3 is loaded. When the battery module 3 slides and stops against the limiting beam 133, the battery module 3 is better assembled in place. The battery modules 3 loaded into the battery box from the access ports on both sides of the battery box can be limited by the limiting beam 133.

[0075] In a possible implementation, the first avoidance holes are provided on both of the two first frame plates 21, and the locking component 5 includes a locking rod 51 and two stoppers 52, the locking rod 51 passes through the locking hole 311 and the two first avoidance holes, and the two stoppers 52 are respectively connected to both ends of the locking rod 51 to fix the locking rod 51. Among them, at least one of the two stoppers 52 is detachably connected to the locking rod 51, for example, by a threaded connection, which facilitates disassembly and assembly.
