For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] Reference below Figure 1-Figure 4 A battery storage box 100 according to an embodiment of the present invention is described.

[0030] like Figure 1 and Figure 2 As shown, the battery storage box 100 according to the embodiment of the utility model includes a box body 1, a box cover 2 and an anti-collision mechanism 3. The box body 1 has a receiving cavity, and the battery pack can be installed in the receiving cavity. The box body 1 can protect the battery pack. The upper side of the box body 1 has an opening connected to the receiving cavity, and the battery pack can be installed into the receiving cavity from the opening. Here, it should be noted that this application only takes the battery pack as an example for explanation. It can be understood that the battery storage box 100 can also be used to place battery cells or battery modules, and this application does not limit it.

[0031] The box cover 2 is detachably installed at the opening, and the box cover 2 is used to open or close the opening. Thus, when the box cover 2 opens the opening, the battery pack can be installed in the accommodating cavity from the opening, and the box cover 2 can also close the opening, thereby protecting the battery pack in the battery placement box 100.

[0032] like Figure 1 and Figure 2As shown, the anti-collision mechanism 3 includes a top plate 31 and an elastic component 32. The top plate 31 is installed on the upper side of the box cover 2. The elastic component 32 is connected between the top plate 31 and the box cover 2. By installing the top plate 31 on the upper side of the box cover 2, the collision impact on the upper side of the battery placement box 100 can first act on the top plate 31, and the top plate 31 can resist the collision impact, thereby avoiding the collision impact from directly acting on the box cover 2. Furthermore, by arranging the elastic component 32 between the top plate 31 and the box cover 2, when the collision impact acts on the top plate 31, the elastic component 32 can be elastically deformed, thereby further absorbing the collision impact, thereby further avoiding the collision impact from directly acting on the box cover 2.

[0033] Therefore, according to the battery placement box 100 of the utility model embodiment, by setting the top plate 31 and the elastic component 32 on the upper side of the box cover 2, the collision impact on the upper side of the battery placement box 100 can first act on the top plate 31, and the top plate 31 can resist the collision impact, thereby avoiding the collision impact directly acting on the box cover 2. Furthermore, by setting the elastic component 32 between the top plate 31 and the box cover 2, when the collision impact acts on the top plate 31, the elastic component 32 can be elastically deformed, thereby further absorbing the collision impact, thereby further avoiding the collision impact directly acting on the box cover 2. Therefore, the battery pack in the battery placement box 100 can be better and more reliably protected.

[0034] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the elastic component 32 includes a guide column 321, a first spring 322 and a guide groove 323. The guide column 321 is installed on the upper surface of the box cover 2; the first spring 322 is sleeved on the guide column 321, and the two ends of the first spring 322 are respectively abutted against the box cover 2 and the top plate 31; the guide groove 323 is set on the top plate 31, and the guide groove 323 is used to cooperate with the guide column 321. Through the cooperation of the guide column 321 and the guide groove 323, the top plate 31 can be allowed to move in the up and down directions relative to the box cover 2.

[0035] Reference Figure 2As shown, a guide column 321 extending in the up-down direction is installed on the upper side of the box cover 2, and a guide groove 323 extending in the up-down direction is provided on the top plate 31, and the opening of the guide groove 323 faces downward. The sliding of the guide column 321 along the guide groove 323 can better limit the movement direction of the top plate 31, so that the top plate 31 can move up and down stably. Furthermore, the upper end of the first spring 322 abuts against the lower surface of the top plate 31, and the lower end of the first spring 322 abuts against the upper surface of the box cover 2. Thus, the first spring 322 can be supported between the top plate 31 and the box cover 2. When the top plate 31 moves up and down, the first spring 322 can be elastically deformed. The elastic deformation of the first spring 322 can absorb the impact of the collision, thereby preventing the battery pack in the battery placement box 100 from being affected.

[0036] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the anti-collision mechanism 3 also includes a limit assembly 33, which includes: a slide bar 331, a slider 332, a connecting rod 333 and a second spring 334. The slide bar 331 is parallel to the top plate 31 and is installed on the lower side of the top plate 31. The slider 332 is slidably arranged on the slide bar 331. One end of the connecting rod 333 is rotatably connected to the upper surface of the box cover 2, and the other end is rotatably connected to the slider 332. The second spring 334 is located between the slider 332 and the top plate 31.

[0037] Optionally, at least two sliders 332 are provided, at least two connecting rods 333 are provided, and the two sliders 332 are rotatably connected to the other ends of the two connecting rods 333. In other words, multiple sliders 332 can be provided, and multiple connecting rods 333 can also be provided, and multiple sliders 332 correspond to multiple connecting rods 333 one by one.

[0038] Reference Figure 2 and Figure 3 The cam 332 is provided with two sliders 332, and the two sliders 332 can be slidably mounted on the slide bar 331. Taking the left and right directions in the figure as an example, the two sliders 332 are respectively adjacent to the left and right side walls of the groove. A mounting seat is installed on the upper surface of the box cover 2. In the left and right directions, the mounting seat is located in the middle of the groove. There are two connecting rods 333, and the lower ends of the two connecting rods 333 can be rotatably fixedly connected to the mounting seat. The upper ends of the two connecting rods 333 are rotatably connected to the two sliders 332, and the second springs 334 are respectively abutted between the sliders 332 and the side walls of the groove. Thus, the two sliders 332, the two connecting rods 333 and the two second springs 334 are symmetrically arranged between the box cover 2 and the top plate 31, thereby making the top plate 31 more stable in terms of its up and down movements.

[0039] Exemplarily, four sliders 332 are provided, and four connecting rods 333 are provided correspondingly. Two sliders 332 are arranged along the front-to-back direction to slide in the front-to-back direction, and the other two sliders 332 are arranged along the front-to-back direction to slide in the front-to-back direction. Figure 2 The left and right directions are arranged in order to slide in the left and right directions.

[0041] like Figure 2 and Figure 4 As shown, the upper ends of the side walls on the left and right sides of the box body 1 are provided with a slot 11 extending in the horizontal direction, and the hook 42 is L-shaped. The hook 42 can be engaged with the slot 11. Specifically, a limit rod 41 extending in the horizontal direction is provided in the mounting hole 21, and the hook 42 can be movably installed on the limit rod 41 left and right. A spring is provided between the hook 42 and the hole wall of the mounting hole 21, and is used to keep the hook 42 in an engaged state with the slot 11, so that the box cover 2 is installed on the box body 1. When the box cover 2 needs to be removed from the box body 1, the hook 42 can be driven and the elastic force of the spring can be overcome. After the spring is deformed, the hook 42 can be disengaged from the slot 11, so that the hook 42 and the slot 11 are unlocked, thereby completing the removal of the box cover 2. The installation method of the box cover 2 and the box body 1 is simple and convenient, and the assembly efficiency is high.

[0042] Furthermore, a plurality of slots 11 may be provided at the opening of the box body 1 , and thus a plurality of hooks 42 may be provided to match the slots 11 one by one, thereby improving the reliability of the box cover 2 after assembly.

[0043] In some embodiments of the utility model, the battery placement box 100 also includes a heat dissipation assembly 5, which includes: at least one heat dissipation fan 51, which is installed on the first wall panel 12 of the box body 1; and a heat dissipation hole 52, which is arranged on the second wall panel 13 of the box body 1.

[0044] In such Figure 1 and Figure 2In an example shown, the first wall panel 12 of the box body 1 is the front wall panel of the box body 1, and the second wall panel 13 can be two wall panels on the left and right sides of the box body 1, that is, the left wall panel and the right wall panel. Two cooling fans 51 are arranged on the front wall panel. One of the two cooling fans 51 can be an air intake fan for taking air into the battery placement box 100, and the other cooling fan 51 can be an air outlet fan for blowing air out of the battery placement box 100. Therefore, by arranging two cooling fans 51, the battery pack in the battery placement box 100 can be better cooled.

[0045] Optionally, a plurality of heat dissipation holes 52 may be provided on both the left wall plate and the right side in the up and down directions. The heat dissipation holes 52 may be long strip-shaped holes. By providing a plurality of heat dissipation holes 52, the heat dissipation capacity of the battery placement box 100 may be further improved.

[0046] Alternatively, if Figure 1 As shown, a cylindrical air duct shell 14 may also be installed on the front side of the front wall plate, and the cylindrical air duct shell 14 may be opposite to the heat dissipation fan 51 , thereby constructing the air duct shell 14 .

[0047] Optionally, the first wall panel 12 may also be the rear wall panel of the box body 1, that is, the cooling fan 51 is arranged on the rear wall panel of the box body 1; optionally, the front wall panel and the rear wall panel of the box body 1 may be both provided with cooling fans 51, for example, the cooling fan 51 arranged on the front wall panel is an air inlet fan, and the cooling fan 51 arranged on the rear wall panel is an air outlet fan. Of course, it can be understood that the battery placement box 100 of the utility model may also have other arrangements of cooling fans 51 and cooling holes 52, and the utility model is not limited thereto.

[0048] Alternatively, if Figure 1 and Figure 2 As shown, the heat dissipation assembly 5 further includes a dust cover plate 61, which is disposed on the outer surface of the second wall plate 13 and is disposed adjacent to the heat dissipation hole 52, and is used to cover a portion of the opening of the heat dissipation hole 52; as shown in the accompanying drawings, the dust cover plate 61 is irradiated at the opening of the heat dissipation hole 52, which can prevent external impurities from entering the battery placement box 100 from the heat dissipation hole 52, and is conducive to protecting the environment in the battery placement box 100. A plurality of dust cover plates 61 are provided, and the plurality of dust cover plates 61 correspond to the plurality of heat dissipation holes 52 one by one.

[0049] Alternatively, if Figure 1 and Figure 2The heat dissipation assembly 5 further includes a dust filter 62, which is disposed in the heat dissipation hole 52. As shown in the accompanying drawings, the dust filter 62 is irradiated in the heat dissipation hole 52, which can prevent external impurities from entering the battery placement box 100 through the heat dissipation hole 52, which is beneficial to protecting the environment in the battery placement box 100. A plurality of dust filters 62 are provided, and the plurality of dust filters 62 correspond to the plurality of heat dissipation holes 52 one by one.

The first buffer block 63 is installed on the upper side of the top plate 31, and the second buffer block 64 is installed on the lower side of the box body 1. Therefore, the upper and lower sides of the battery placement box 100 are protected by the first buffer block 63 and the second buffer block 64, which can better prevent the battery placement box 100 from being damaged. For example, when the battery placement box 100 is transported and installed, the battery placement box 100 can be better protected by the first buffer block 63 and the second buffer block 64, and when the battery placement box 100 is subjected to a collision impact, the collision impact can also be better absorbed to prevent the battery placement box 100 from being damaged.

[0051] Alternatively, if Figure 1 and Figure 2 As shown, the second buffer pad 64 has a corrugated structure. The corrugated structure can effectively disperse the force and enhance the bearing capacity and compressive strength of the pad. The corrugated structure uses a wavy structural design to allow the material to share pressure in all directions, thereby greatly improving the mechanical properties of the second buffer pad 64. The corrugated structure can reduce the amount of material used while ensuring a certain strength, achieving the purpose of lightweighting and saving resources. The air layer formed by the corrugated structure helps to improve the heat insulation and sound insulation performance of the pad.
