[0031] In order to solve the problem in the prior art that the crossbeams of the battery box structure are fixed inside the battery box, which makes it inconvenient to place the batteries and can only install batteries of fixed specifications and sizes, which has limitations in use, this embodiment provides a battery box structure.

[0032] like Figures 1 to 4 As shown, the battery box structure includes a box body 10, a support rod 20, a cross beam plate 30 and a locking member 40. The box body 10 has an installation groove 101 for installing the battery 50. The support rod 20 is arranged inside the box body 10. The support rod 20 extends along a first direction. Both ends of the support rod 20 are fixedly connected to the box body 10. There are two groups of support rods 20. The two groups of support rods 20 are spaced apart along a second direction perpendicular to the first direction. Along the second direction, the two groups of support rods 20 respectively abut on both sides of the battery 50. The cross beam plate 30 is slidably set on the support rod 20. The support rod 20, the cross beam plate 30 and part of the box body 10 form an installation space for the battery 50. The locking member 40 is movably set on the support rod 20. The locking member 40 abuts on the side of the cross beam plate 30 away from the battery 50 for limiting the cross beam plate 30.

[0033] Specifically, the battery box structure of the present application adopts a crossbeam plate 30 that is movably arranged inside the box body 10. By adjusting the position of the crossbeam plate 30 inside the box body 10, it can cooperate with the box body 10 to clamp the battery pack. Multiple batteries 50 are stacked along a first direction to form a battery pack, and battery packs of different specifications are formed according to the number of batteries 50; and the movably arranged crossbeam plate 30 can provide avoidance during the installation of the battery 50, so that the battery pack can be clamped by moving the crossbeam plate 30 after the installation of the battery 50 is completed.

[0034] Here, along the first direction, the battery pack abuts between the crossbeam plate 30 and the inner surface of the box body 10 to achieve stable clamping of the battery pack.

[0035] Furthermore, the present application utilizes a slidable connection between the crossbeam 30 and the support rods 20 to guide and limit the crossbeam 30, facilitating its movement. Simultaneously, the support rods 20 support the battery 50 on both sides in the second direction, clamping the battery 50 and thereby securing the battery 50 and improving the stability of its installation. The two sets of support rods 20 position the battery 50 in the second direction, while the crossbeam 30 and the housing 10 form a first-direction positional arrangement for the battery 50, thereby securing the battery 50 within the mounting slot 101.

[0036] There is one or more battery packs. When there are multiple battery packs, the multiple battery packs are arranged inside the mounting groove 101 along the second direction.

[0037] The first direction is Figure 1 The X direction is shown, and the second direction is Figure 1 The first direction and the second direction are perpendicular to each other in the horizontal plane.

[0038] The present application sets a locking member 40 on the side of the beam plate 30 away from the battery 50 to limit the beam plate 30, so as to fix the beam plate 30, thereby ensuring that the beam plate 30 maintains abutment with the battery 50, thereby improving the installation stability of the beam plate 30.

[0039] In this embodiment, the support rod 20 is a screw, and the locking member 40 is a nut that engages with the screw thread. By turning the nut, the nut moves axially along the screw, thereby abutting against the crossbeam 30 at a predetermined position. With the screw thread locked, the crossbeam 30 cannot move away from the battery 50. The structural coordination of the screw and nut simplifies the structure, improves the stability of the crossbeam 30 installation, and facilitates operation at a low cost.

[0040] In order to improve the accuracy of the movement of the crossbeam plate 30 and ensure that the crossbeam plate 30 fits seamlessly on the battery 50, scale lines are set on the support rods 20 to facilitate position adjustment.

[0041] like Figure 1 As shown, the top surface of the crossbeam plate 30 has a receiving groove 320 , and the receiving groove 320 is used to place the output pole seat of the battery 50 .

[0042] The receiving slots 320 are arranged in a one-to-one correspondence with the battery packs.

[0043] Furthermore, the battery box structure further includes two fixing plates 60 disposed inside the box body 10 . The two fixing plates 60 are spaced apart along the first direction, and the crossbeam plate is disposed between the two fixing plates 60 .

[0044] Furthermore, the fixing plate 60 may be detachably connected to the box body, or may be integrally formed on the box body.

[0045] In this embodiment, both ends of the support rod are fixedly connected to two fixing plates 60 respectively, and the support rod is connected to the box body through the fixing plates 60 .

[0046] like Figures 1 to 3 As shown, the bottom surface of the mounting groove 101 has a convex rib 110 protruding toward the side of the battery 50, and the convex rib 110 extends along the first direction. The surface of the crossbeam plate 30 facing the bottom surface of the groove has a sliding groove 310, and at least a portion of the convex rib 110 extends into the interior of the sliding groove 310 and slides with the sliding groove 310.

[0047] Specifically, through the structure of sliding cooperation between the rib 110 and the slide groove 310, the crossbeam plate 30 is enabled to slide along the first direction, which is beneficial to improving the sliding stability of the crossbeam plate 30, while also avoiding the phenomenon of deviation of the crossbeam plate 30 during the sliding process, thereby ensuring the stability of the clamped battery 50.

[0048] Furthermore, a plurality of ribs 110 are provided, and the plurality of ribs 110 are spaced apart along the second direction. The ribs 110 are provided in a one-to-one correspondence with the chute 310 . The provision of the plurality of ribs 110 is conducive to further enhancing the sliding stability of the crossbeam plate 30 .

[0049] In this embodiment, the rib 110 is disposed between two adjacent battery packs along the second direction, so that a heat dissipation gap is formed between the two battery packs, which is beneficial to heat dissipation of the battery 50 and improves the use efficiency of the battery 50.

[0050] like Figure 1 As shown, each group of support rods 20 is provided with at least a plurality of support rods 20 , and the plurality of support rods 20 are spaced apart along the height direction of the box body 10 .

[0051] It is understood that a plurality is at least two.

[0052] Specifically, the provision of multiple support rods 20 is beneficial to increasing the contact area between the support rods 20 and the battery 50, thereby further improving the stability of the installation of the battery 50.

[0053] Furthermore, a plurality of support rods 20 are arranged at equal intervals along the height direction of the box body 10, wherein the height direction of the box body 10 is Figure 1 The Z direction is shown.

[0054] In this embodiment, the crossbeam 30 is a hollow structure. Preferably, the hollow area inside the crossbeam 30 corresponds to the position of the battery pack. The hollow crossbeam 30 can absorb the expansion force of the battery 50 through deformation, reducing the probability of thermal runaway and improving safety.

[0055] In this embodiment, the crossbeam 30 is a rectangular plate structure with through-holes at its four corners. Each set of support rods 20 is provided with two, with each of the four support rods 20 extending through the four through-holes. The four support rods 20 guide and limit the four through-holes of the crossbeam 30, ensuring stable installation and movement of the crossbeam 30. The rectangular plate structure also facilitates contact with the battery pack, increasing the contact area between the crossbeam 30 and the battery pack, thereby enhancing the stability of the battery pack's installation.
