[0030] This utility model provides a wall-mounted stacking device for battery packs, including a first connector and a second connector. The first connector is installed on a first side wall of the battery pack, and the second connector is fixed to the wall. The first connector has a first connecting part, the second connector has a second connecting part, and the second connector is provided with an observation hole, through which the cooperation and installation of the first connecting part and the second connecting part can be viewed.

[0031] Example 1

[0032] like Figure 1-8 As shown, this embodiment discloses a wall-mounted stacking device for battery packs, including a first connector 100 and a second connector 200. The first connector 100 is installed on a first side wall 400 of the battery pack, and the second connector 200 is fixed to the wall. The first connector 100 has a first connecting portion, and the second connector 200 has a second connecting portion. The second connector 200 is provided with an observation hole 210, through which the installation of the first connecting portion and the second connecting portion can be viewed. This allows for observation of whether the first connecting portion and the second connecting portion are aligned during the installation of the battery pack, thereby reducing the difficulty of battery pack installation.

[0033] Specifically, the first sidewall 400 is the back of the outer casing of the battery pack.

[0034] like Figure 5 As shown, in this embodiment, the second connector 200 includes a first back plate 220 and first side plates 230 disposed on both sides of the first back plate 220. Observation holes 210 are formed on the first side plates 230. The two first side plates 230 are respectively disposed at both ends of the first back plate 220 and are both perpendicular to the first back plate 220. The observation holes 210 are provided in the middle of both first side plates 230, and the junction of the observation holes 210 and the first side plates 230 is set with arc-shaped chamfers. Both ends of the upper surface of the first side plates 230 are set with arc-shaped chamfers.

[0035] like Figure 3 , 5 As shown, specifically, the second connecting part is a hook 240 provided on the side of the first back plate 220 near the battery pack, and the hook 240 is located in the middle of the first back plate 220. The first back plate 220 is provided with first bolt holes 250 symmetrically distributed along the hook 240. The first bolt holes 250 are used to fix the second connector 200 to the wall.

[0036] The hook 240 is integrally formed with the first back plate 220. Specifically, during the processing of the hook 240, a cuboid with only one side connected to the first back plate 220 is first cut out. Then, this cuboid is bent towards the first side plate 230 of the first back plate 220 to form an L-shaped hook 240, thereby creating an opening in the first back plate 220. Furthermore, the top of the hook 240 is provided with a guide edge, which is inclined towards the extending direction of the first side plate 230 to facilitate smooth engagement between the first connecting part and the hook 240.

[0037] Furthermore, the horizontal plane containing the upper edge of the hook 240 lies between the horizontal plane containing the upper edge of the observation hole 210 and the horizontal plane containing the lower edge of the observation hole 210. When the first connecting part of the first connector 100 is engaged with the hook 240, the relative positions of the first connecting part and the hook 240 can be clearly seen through the observation hole 210. When the first connector 100 and the second connector 200 are engaged, it is only necessary to ensure that the lower edge of the first connecting part is above the upper edge of the hook 240, and then align the first connecting part and the hook 240 to smoothly hook the first connecting part into the hook 240.

[0038] like Figure 4 As shown, the first connector 100 includes a groove 110 and mounting portions 120 disposed on both sides of the groove 110. The mounting portion 120 is provided with a second bolt hole 130, and the outer casing of the battery pack is provided with bolt holes corresponding to the second bolt holes 130. The first connector 100 can be connected to the battery pack by bolts. The groove 110 is hooked onto the hook 240 to realize the connection between the first connector 100 and the second connector 200, thereby hanging the battery pack on the wall.

[0039] like Figure 5 As shown, the first distance between the first side plate 230 and the hook 240 is greater than or equal to the sum of the first diameter of the bolt head end installed in the first bolt hole 250 and the maximum distance that the first side plate 230 can move to one side of the groove 110.

[0040] Specifically, in this embodiment, the first back plate 220 is connected to the wall by bolts. After installation, the head of the bolt is located on the side of the first back plate 220 where the first side plate 230 is located. To ensure that the groove 110 can be smoothly engaged with the hook 240, the width of the groove 110 is greater than the width of the hook 240. In the actual installation process, it is impossible to guarantee that the groove 110 and the hook 240 are perfectly aligned (the hook 240 is exactly in the middle of the groove 110), and the center line of the groove 110 will deviate from the center line of the hook 240. Therefore, the hook 240 and the bolt head installed in the first bolt hole 250 need to maintain a certain distance to ensure that the groove 110 has sufficient installation allowance to avoid interference and collision between the groove 110 and the bolt head.

[0041] Generally, a washer is also placed between the bolt and the first back plate 220, and the larger of the diameter of the washer and the bolt head is taken as the first diameter. Specifically, the first distance between the first side plate 230 and the hook 240 should be greater than or equal to 25mm. In this embodiment, the first distance between the first side plate 230 and the hook 240 is set to 30mm.

[0042] like Figure 1 , 2As shown, the wall-mounted stacking device also includes a third connector 300 disposed on the second side wall 410. The second side wall 410 is the front part of the outer casing of the battery pack and is opposite to the first side wall 400. The first connector 100 is provided with a third connecting part, and the third connector 300 is provided with a fourth connecting part. When multiple battery packs are stacked, the first connector 100 on the first side wall 400 of the upper battery pack is connected to the fourth connecting part of the third connector 300 on the second side wall 410 of the lower battery pack through the third connecting part.

[0043] like Figure 1 , 2 As shown, there are four first connectors 100 and four second connectors 200. All four second connectors 200 are fixed to the wall. Two first connectors 100 are provided on each of the two sides of the first sidewall 400 in the width direction, and these two first connectors 100 are aligned with each other in the width direction. The four second connectors 200 are aligned with the four first connectors 100. When the battery pack is attached, the four first connectors 100 cooperate with the four second connectors 200 for installation.

[0044] like Figure 4 , 6 As shown, specifically, the third connector 300 includes a second back plate 310 and second side plates 320 disposed on both sides of the second back plate 310. The two second side plates 320 constitute a fourth connecting portion, and the third connecting portion is a connecting piece 140 disposed on the mounting portion 120 on one side of the first connector 100 (near the edge of the first sidewall 400). When multiple battery packs are stacked, the connecting piece 140 on the first connector 100 of the upper battery pack is inserted between the two second side plates 320 of the third connector 300 of the lower battery pack. The two ends of the connecting piece 140 are located between the two second side plates 320.

[0045] like Figure 4 , 6 As shown in Figures 7 and 8, furthermore, the second back plate 310 is provided with a third bolt hole 330 and a fourth bolt hole 340. The third bolt hole 330 is located in the middle of the upper part of the second back plate 310, and multiple fourth bolt holes 340 are symmetrically distributed on both sides of the bottom of the second back plate 310. Specifically, there are two fourth bolt holes 340, and the third bolt hole 330 and the two fourth bolt holes 340 are arranged in an isosceles triangle shape. The connecting piece 140 is also provided with a fifth bolt hole 150. When the connecting piece 140 is engaged with the third connecting member 300, the length direction of the connecting piece 140 is set along the opposite direction of the two second side plates 320, the side wall of the connecting piece 140 is in contact with the inner side wall of the second back plate 310, and the fifth bolt hole 150 is aligned with the third bolt hole 330. Then, the connecting piece 140 and the third connecting member 300 are fixed by bolts.

[0046] Furthermore, the fourth bolt hole 340 is used to fix the third connector 300 to the third side wall 420 of the battery pack. The third side wall 420 is perpendicular to the first side wall 400 and the second side wall 410, respectively, and both ends of the third side wall 420 are connected to the first side wall 400 and the second side wall 410, respectively. That is, the bottom of the third connector 300 is fixed to the third side wall 420, and the top extends upward to above the second side wall 410.

[0047] Specifically, there are four third connectors 300, and the positions of the four third connectors 300 on the second side wall 410 correspond to the positions of the four first connectors 100 on the first side wall 400.

[0048] like Figure 6 As shown, the second back plate 310 is further provided with a reinforcing rib unit, which includes a first reinforcing rib 350 and a second reinforcing rib 360. The first reinforcing rib 350 extends from one side of the upper part of the second back plate 310 toward the middle of the lower part, and the second reinforcing rib 360 extends from the other side of the upper part of the second back plate 310 toward the middle of the lower part, and the two meet at the middle position of the lower part of the second back plate 310. This arrangement cleverly avoids the third bolt hole 330 and the fourth bolt hole 340, ensuring the length of the first reinforcing rib 350 and the second reinforcing rib 360, thereby improving the strength of the second back plate 310.

[0049] The wall-mounted stacking device of this invention connects a first connector 100 fixed to the battery pack with a second connector 200 fixed to the wall to secure the battery pack to the wall. The second connector 200 has an observation hole 210, which allows for effective monitoring of the alignment of the first connector 100 and the second connector 200 during battery pack installation, thus reducing the difficulty of battery pack installation. Furthermore, when multiple battery packs are stacked, the connecting piece 140 of the first connector 100 on the upper battery pack connects to the fourth connecting part of the third connector 300 on the lower battery pack, enabling neat stacking of multiple battery packs and ensuring the stability of the stacked battery packs.

[0050] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
