[0002] A battery box is a device or structure used to house, protect, and manage batteries. It typically includes a base and a cover, and both are often made of magnesium alloy because magnesium alloys have excellent thermal conductivity, enabling effective heat dissipation. During battery charging and discharging, this helps maintain the battery's temperature balance, prevents overheating, and improves battery efficiency and safety.

[0003] The existing high-heat-dissipation magnesium alloy battery box has the following disadvantages during use:

[0004] When installing and fixing multiple battery packs in a battery box, the battery packs are usually placed in the bottom box first, and then each battery pack is fixed in the bottom box one by one with bolts or screws. Then the box cover is locked with bolts. This method results in low efficiency in installing and fixing multiple battery packs in the bottom box and cannot meet the daily assembly needs of battery boxes. Therefore, a high heat dissipation magnesium alloy battery box is needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-heat-dissipation magnesium alloy battery box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-heat-dissipation magnesium alloy battery box, including a base box, with multiple heat dissipation grooves on both side walls of the base box, a cover slidably connected to the top of the base box, bolts movably inserted around the top of the cover, and screw holes cooperating with the bolts around the top of the base box, two symmetrically arranged guide strips fixed to the bottom of the cover, both guide strips having an L-shaped vertical cross-section, and a cover-closing linkage fixing assembly installed inside the base box, which also cooperates with the left ends of the two guide strips; the cover-closing linkage fixing assembly is used to achieve synchronous positioning of multiple battery packs placed inside the base box when the cover slides closed at the top of the base box.

[0007] In a preferred embodiment, both the base box and the box cover are made of magnesium alloy.

[0008] In a preferred embodiment, the cover-closing linkage fixing assembly includes two symmetrically arranged U-shaped movable plates that slide inside the bottom box. Two symmetrically arranged guide rods are provided on both sides of the two U-shaped movable plates and fixed to the inside of the bottom box. Two symmetrically arranged sliding sleeves are slidably sleeved on the outer side of each guide rod and the sliding sleeves are fixed to the outer wall of the U-shaped movable plate.

[0009] In a preferred embodiment, multiple sets of equidistant positioning components are fixed to one side wall of each of the two U-shaped movable plates facing each other. Each set of positioning components includes two positioning plates. The top of each of the two positioning plates is provided with a second inclined surface, and the two second inclined surfaces are arranged in opposite directions. The top sides of the two U-shaped movable plates are provided with a first inclined surface.

[0010] In a preferred embodiment, each of the two U-shaped movable plates has a trigger seat fixedly connected to the middle of its opposite side wall. Each of the two trigger seats has a third inclined surface on its side wall facing the box cover. Each of the two U-shaped movable plates has its opposite side wall fixed to the inner wall of the bottom box by a plurality of rectangular array S-shaped spring pieces. Each of the two guide strips has a fourth inclined surface at its left end that cooperates with the third inclined surface.

[0011] In a preferred embodiment, both of the U-shaped movable plates are provided with multiple equidistant lightweight slots.

[0012] Compared with the prior art, the high heat dissipation magnesium alloy battery box provided by this utility model has at least the following beneficial effects:

[0013] In this invention, when using the high heat dissipation magnesium alloy battery box, multiple battery packs are first placed one by one in the bottom box, and each battery pack is limited on both sides by two positioning plates. This completes the pre-positioning of each battery pack. Then, by manually pushing the box cover to the left, the fourth inclined surfaces on the left ends of the two guide strips at the bottom of the box cover contact and press the third inclined surfaces on the actuating seat, thereby causing the two U-shaped moving plates to move towards each other and simultaneously clamp and fix the multiple battery packs, achieving further fixation.

[0023] Example

[0024] When installing and fixing multiple battery packs in a battery box, the battery packs are usually placed in the bottom box first, and then each battery pack is fixed in the bottom box one by one with bolts or screws. Then the box cover is locked with bolts. This results in low efficiency in installing and fixing multiple battery packs in the bottom box and cannot meet the daily assembly needs of battery boxes.

[0025] For this purpose, please refer to Figure 1-5This utility model provides a high heat dissipation magnesium alloy battery box, including: a base box 1, with multiple heat dissipation grooves 11 on both side walls of the base box 1, a box cover 3 slidably connected to the top of the base box 1, bolts 31 movably inserted around the top of the box cover 3, and screw holes 33 that cooperate with the bolts 31 around the top of the base box 1, and two symmetrically arranged guide strips 32 fixed to the bottom of the box cover 3, the vertical cross section of the two guide strips 32 being L-shaped, and a cover-closing linkage fixing assembly 4 installed on the inner side of the base box 1, which also cooperates with the left end of the two guide strips 32; the cover-closing linkage fixing assembly 4 is used to achieve synchronous positioning of multiple battery packs 2 placed inside the base box 1 when the box cover 3 slides closed at the top of the base box 1.

[0026] Further as Figure 1-5 As shown, it is worth noting that both the bottom box 1 and the box cover 3 are made of magnesium alloy.

[0027] Magnesium alloys have excellent thermal conductivity, enabling effective heat dissipation. During battery charging and discharging, they help maintain the battery's temperature balance, prevent overheating, and improve battery efficiency and safety.

[0028] Further as Figure 1-5 As shown, it is worth noting that in order to fix or remove multiple battery packs 2 inside the battery box by means of opening and closing the cover 3, a cover-closing linkage fixing assembly 4 is provided, which includes two symmetrically arranged U-shaped moving plates 41 that slide inside the bottom box 1. Two symmetrically arranged guide rods 43 are fixed to the inside of the bottom box 1 on both sides of the two U-shaped moving plates 41. Two symmetrically arranged sliding sleeves 42 are slidably fitted on the outer side of each guide rod 43. The sliding sleeves 42 are fixed to the outer wall of the U-shaped moving plates 41. Multiple sets of equidistantly arranged positioning components are fixed to one of the opposite side walls of the middle of the two U-shaped moving plates 41. Each positioning component includes two positioning plates 45. The top of each of the two positioning plates 45 is provided with a second inclined surface 46, and the two second inclined surfaces 46 are arranged in opposite directions. The top sides of each of the two U-shaped moving plates 41 are provided with a first inclined surface 44. The middle of the side wall of each of the two U-shaped moving plates 41 facing away from each other is fixed with a trigger seat 47. The side wall of each of the two trigger seats 47 facing the box cover 3 is provided with a third inclined surface 48. The side wall of each of the two U-shaped moving plates 41 facing away from each other is fixed to the inner wall of the bottom box 1 by a plurality of rectangular array S-shaped spring pieces 49. The left end of each of the two guide bars 32 is provided with a fourth inclined surface 410 that cooperates with the third inclined surface 48. The two U-shaped moving plates 41 are provided with a plurality of equidistant lightweight grooves 411.

[0029] In the case of the cover-closing linkage fixing assembly 4, each component can be made of magnesium alloy. The length of the cover 3 is greater than the length of the guide strip 32. The design of the second inclined surface 46 and the first inclined surface 44 is to facilitate the insertion of the battery pack 2 and to guide the insertion. The third inclined surface 48 and the fourth inclined surface 410 are set in parallel and at the same height. When the fourth inclined surface 410 moves towards the third inclined surface 48, it can squeeze the touch seat 47, thereby causing the two U-shaped moving plates 41 to move towards each other and causing the multiple S-shaped springs 49 to stretch. The lightweight groove 41 is to reduce the overall weight of the U-shaped moving plate 41 and to reduce the contact area with the outer surface of the battery pack, thereby reducing the area where heat dissipation is restricted.

[0030] In summary: When using this high-heat-dissipation magnesium alloy battery box, firstly, multiple battery packs 2 are placed one by one in the bottom box 1, and each battery pack 2 is limited on both sides by two positioning plates 45. This completes the pre-placement of each battery pack 2. Then, by manually pushing the box cover 3 to the left, the fourth inclined surface 410 on the left end of each of the two guide strips 32 at the bottom of the box cover 3 contacts and presses the third inclined surface 48 on the touch seat 47, thereby causing the two U-shaped moving plates 41 to move towards each other and simultaneously clamp and fix the multiple battery packs 2, achieving further fixation. This achieves the goal of quickly fixing multiple battery packs 2 without screws, thus greatly improving the rapid assembly efficiency of the battery box, meeting the daily assembly needs of battery boxes, and having a good performance.
