[0031] Example 1

[0032] See Figure 1This utility model provides a fixing device for connecting to a battery pack. The battery pack includes a battery module (not shown in the figure) and a housing 5. The battery module is fixedly connected to the side wall of the housing 5 in the third direction Z. The side wall of the housing 5 includes a connection area (not shown in the figure) connected to the battery module and a peripheral area (not shown in the figure) surrounding the outer edge of the connection area. The fixing device includes a base 1 and a clamping member 2. A receiving space for placing the battery pack is formed between the clamping member 2 and the base 1. The clamping member 2 can move along a preset direction and the third direction Z so that the clamping member 2 can selectively abut against the peripheral area and restrict the position of the peripheral area on the base 1. The preset direction is the extension direction of the outer edge of the connection area.

[0033] In this way, the base 1 can stably support the battery pack. By moving the clamping member 2 along the preset direction and the third direction Z, the clamping member 2 can be moved to the corresponding peripheral area according to the position of the battery module to be disassembled and abut against the peripheral area. The battery pack is placed in the accommodating space between the base 1 and the clamping member 2, which can restrict the position of the battery pack in the third direction Z, prevent the housing 5 from loosening when disassembling the battery module, and avoid affecting the disassembly effect. This improves the flexibility of the fixing device, enabling it to adapt to battery packs of different sizes, and improves the disassembly efficiency of the battery module and the stability of the housing 5 during disassembly.

[0034] In this embodiment, the bottom surface of the base 1 is provided with rollers 11 to facilitate moving the base 1 to the desired position.

[0035] See Figure 1 In some embodiments, the battery pack includes multiple battery modules, the sidewall of the housing 5 includes multiple connection areas and multiple peripheral areas, and multiple clamping members 2 are provided, each of which can selectively abut against the multiple peripheral areas.

[0036] In this embodiment, multiple connection areas are arranged along the length of the housing 5, and a battery module is provided in each connection area so that when a battery module is disassembled, the clamping member 2 can be moved to the vicinity of the corresponding peripheral area.

[0037] Thus, the clamping component 2 moves in the preset direction and the third direction Z, which can clamp the peripheral area corresponding to the battery module to be disassembled, improve the structural strength of the peripheral area near the battery module to be disassembled, avoid deformation of the peripheral area during disassembly, and improve disassembly efficiency.

[0038] It is understandable that the number and arrangement of battery modules can be adjusted according to actual needs, and are not limited to being arranged along the length of the housing 5, which will not be elaborated here.

[0039] See Figure 1In some embodiments, the connecting area has at least a shape extending along a first direction X and a second direction Y. The preset directions include the first direction X and the second direction Y. The first direction X and the second direction Y are set at an angle. The first direction X and the second direction Y are both perpendicular to the third direction Z. The clamping member 2 includes a limiting part (not shown in the figure) and a clamping part (not shown in the figure). The limiting part is connected to the clamping part. The limiting part can move along the first direction X and the third direction Z. The clamping part can move along the second direction Y.

[0040] In this embodiment, the battery module has a cuboid structure, the connection area is rectangular, the length direction of the battery module and the length direction of the housing 5 are consistent with the first direction X of the connection area, the width direction of the battery module and the width direction of the housing 5 are consistent with the second direction Y of the connection area, and the height direction of the battery module and the height direction of the housing 5 are consistent with the third direction Z of the connection area. The battery module is fixedly connected to the side wall of the housing 5 along the third direction Z, and the limiting part can drive the pressing part to move along the first direction X and the third direction Z.

[0041] In this way, the clamping part can be accurately positioned to the peripheral area, thereby enabling the clamping part 2 to adapt to battery packs of different sizes and improve disassembly efficiency.

[0042] It is understandable that the side connecting the battery module to the sidewall can also be trapezoidal or other shapes. The shape of the connection area is not limited to a rectangle; it can also be trapezoidal or other shapes. The shape of the battery module and the shape of the connection area can be adjusted according to actual needs, and will not be listed in detail here.

[0043] See Figure 1 In some embodiments, multiple clamping parts are provided, each clamping part is movable relative to the limiting part along the second direction Y, and when the clamping part abuts the peripheral area, the clamping parts are distributed around the outer edge of the connecting area.

[0044] In this embodiment, the outer edge of the connecting area includes multiple connecting line segments, and there are multiple corresponding clamping parts. These clamping parts can selectively abut against the peripheral areas corresponding to the multiple line segments. In this way, the multiple clamping parts can clamp the peripheral areas, preventing the housing 5 from shifting or even falling off the base 1, improving the stability and safety of the fixing device. Furthermore, the clamping parts on the same limiting part can be independently adjusted in position, allowing the fixing device to adapt to battery packs of different shapes and sizes, thus improving the flexibility of the fixing device.

[0045] It is understandable that the number and location of the clamping parts can be adjusted according to actual needs, and will not be listed in detail here.

[0046] See Figure 1In some embodiments, the clamping member 2 further includes a fixing part, and the limiting part is slidably disposed on the fixing part along the third direction Z. The fixing part is connected to the base 1 and the limiting part. The base 1 has a plurality of first limiting holes 12 along the first direction X. The fixing part has a second limiting hole 231. The second limiting hole 231 can be selectively fixed to the first limiting hole 12 located at a preset position in the first direction X by fasteners, so that the fixing part is fixedly disposed on the base 1. The limiting part and the fixing part are detachably connected.

[0047] In this embodiment, the fixing part is a fixing rod 23, which extends along the third direction Z. A fixing seat 232 is fixedly connected to one end of the fixing rod 23 facing the base 1. A second limiting hole 231 is opened in the fixing seat 232, so that the fixing seat 232 and the base 1 are connected by fasteners to facilitate the adjustment of the relative position of the fixing rod 23 and the base 1. The fasteners are bolts.

[0048] Thus, by opening a first limiting hole 12 on the base 1 along the first direction X, it is easy to adjust the position of the fixing part in the first direction X. Under the action of the fastener, the fixing part can be stably connected to the base 1, so that it can support the limiting part, improve the stability and reliability of the fixing device, and enable the fixing device to adapt to battery packs of different specifications, thereby improving the flexibility of the fixing device.

[0049] It is understandable that the fixing part can also be a slider structure that is slidably set on the base 1. The specific structure of the fixing part can be adjusted according to actual needs, as long as it can adjust the position of the limiting part in the first direction X and the third direction Z. It will not be listed in detail here.

[0050] See Figure 1 In some embodiments, the limiting part includes two limiting rods 21 arranged at intervals along the first direction X. Both limiting rods 21 extend along the second direction Y. The two ends of the limiting rods 21 are respectively slidably connected to the corresponding fixing part along the third direction Z to limit and press the battery pack.

[0051] In this embodiment, a limiting rod 21 is provided with two pressing parts. The limiting rod 21 is located above the housing 5. The fixing rod 23 is provided with a plurality of third limiting holes 233 spaced apart along the third direction Z. The two ends of the limiting rod 21 are respectively fixedly connected to the connecting sleeves 212 sleeved on the fixing rod 23, and the two ends of the limiting rod 21 are respectively provided with a fixing rod 23, so that the fastener can pass through the connecting sleeves 212 and connect with the third limiting holes 233, thereby realizing the fixed connection between the limiting rod 21 and the fixing rod 23. The fastener is a bolt. By moving the fixing rods 23 at both ends of the limiting rod 21 along the first direction X, the relative position of the limiting rod 21 and the base 1 can be adjusted, so that the limiting rod 21 moves to the corresponding peripheral area.

[0052] Thus, by adjusting the position of the limiting rod 21 in the first direction X, the limiting rod 21 can be moved to the peripheral area near the battery module to be disassembled and offset from the battery module, avoiding interference between the battery module and the limiting part and the clamping part during disassembly. That is, when the clamping part 2 abuts against the peripheral area, along the third direction Z, the projection of the clamping part 2 on the side wall of the housing 5 does not overlap with the projection of the battery module between the connecting area and the clamping part on the side wall of the housing 5. This facilitates the removal of the battery module to be disassembled from the channel formed by two adjacent limiting rods 21. The fixing rod 23 can provide stable support for both ends of the limiting rod 21. The fixing rod 23 drives the limiting rod 21 to move along the first direction X, so that the clamping part can press against the peripheral area of ​​the housing 5, facilitating the stable removal of the battery module from the housing 5, improving the disassembly efficiency of the battery module and the stability of the battery pack during disassembly.

[0053] It is understandable that the limiting part can also be a rectangular frame structure, with the hollow part used for the battery module to pass through; multiple limiting rods 21 can also be provided, and multiple limiting rods 21 can share the middle limiting rod 21, that is, two channels are formed between three limiting rods 21, or they can not share the middle limiting rod 21, that is, two channels are formed between four limiting rods 21. The number of limiting rods 21 can be adjusted according to actual needs, which will not be listed in detail here; the fasteners can also be fastening buckles, pins, etc., and the specific structure of the fasteners can be adjusted according to actual needs.

[0054] See Figure 1 In some embodiments, the pressing part can be selectively slidably disposed on the limiting part along the second direction Y. Further, in some embodiments, the limiting rod 21 has an adjustment hole 211 extending along the second direction Y, and the pressing part can be selectively slidably disposed in the adjustment hole 211 so that the pressing part moves along the second direction Y.

[0055] In this embodiment, a limiting rod 21 has four adjustment holes 211. The clamping part is detachably connected to the limiting rod 21. The clamping part is a locking clip 22. The locking clip 22 is disposed in the adjustment hole 211 and moves along the second direction Y. The adjustment hole 211 is disposed through the surface of the limiting rod 21 in the third direction Z (that is, the top and bottom surfaces of the adjusting rod). The locking clip 22 is disposed through the adjustment hole 211 and is slidably connected to the limiting rod 21 along the second direction Y, so that the end of the locking clip 22 facing the box 5 can clamp the edge of the box 5 and limit the relative position of the box 5 and the base 1.

[0056] Thus, the locking clip 22 slides within the adjusting hole 211, allowing adjustment of its position in the second direction Y. By adjusting the position of the fixing rod 23, the locking clip 22 can be positioned in the first direction X and the third direction Z, achieving precise positioning of the locking clip 22. This allows the locking clip 22 to move to the desired position and abut against the peripheral area, limiting the relative position of the housing 5 and the base 1. This enables the fixing device to adapt to battery modules of different sizes, improving its versatility. The locking clip 22 can clamp the periphery of the housing 5, preventing the housing 5 from shaking or shifting during disassembly, thus improving the stability of the battery pack and the efficiency of battery module disassembly.

[0057] It is understood that the clamping component 2 can also be a clamping block. The clamping block is connected to a connecting rod that passes through the adjustment hole 211, so that the clamping block can move along the second direction Y. The limiting rod 21 drives the clamping block to move along the third direction Z, so that the clamping block can tightly abut against the edge of the box 5, thereby clamping the box 5. The specific structure of the clamping component 2 can be adjusted according to actual needs, and will not be listed in detail here. In addition, a buffer pad can be provided on the contact surface between the clamping component 2 and the box 5 to avoid the clamping component 2 from damaging the surface of the box 5.

[0058] See Figure 2 This utility model also provides a battery module disassembly system, which includes a lifting device 3 and a fixing device. The battery module is provided with a lifting position (not shown in the figure). The lifting device 3 includes a hook 31, which can be selectively connected to the lifting position for lifting the battery module out along the third direction Z.

[0059] In this embodiment, both ends of the battery module are provided with lifting positions, and the hooks 31 are provided one-to-one with the lifting positions so that the battery module can be separated from the housing 5.

[0060] Thus, by moving the two limiting rods 21 to the sides of the battery module to be disassembled, and moving the clamping member 2 to make it tightly abut against the surrounding area, the hook 31 can be hooked onto the lifting position, which can lift the battery module upward, detach it from the side wall of the box 5, and move it to the outside through the channel formed between the two limiting rods 21. Since the clamping member 2 can fix the box 5 to the base 1, it can improve the stability of the battery pack during the disassembly of the battery module and avoid interference between the battery module and the limiting rods 21, thereby improving the disassembly efficiency of the battery module.

[0061] It should be noted that the method of lifting the battery module by combining the hook 31 with the lifting position of the battery module is existing technology and will not be described in detail here.

[0062] See Figures 2 to 6 In some embodiments, the lifting device 3 further includes a lifting tool 32 and a lifting frame 33, both of which are connected to the hook 31.

[0063] In this embodiment, the hook 31 and the lifting device 32 are detachably connected. After the hook 31 is assembled to the lifting device 32, the hook 31 is connected to the lifting position of the battery module. By connecting the lifting rope to the lifting device 32, the lifting equipment connected to the lifting rope can lift both sides of the battery module respectively, so that the battery module is disconnected from the box 5. The hook 31 and the lifting frame 33 are detachably connected. After the hook 31 is assembled to the lifting frame 33, the lifting rope can lift the battery module through the channel between the two limiting rods 21 along the third direction Z to the outside of the box 5. Both the lifting device 32 and the lifting frame 33 are provided with lifting lugs (not shown in the figure) connected to the lifting rope.

[0064] Thus, by setting up the lifting device 32 and the hanger 33, the battery module can be stably lifted and moved out of the box 5 through the channel, improving the efficiency of battery module disassembly. When disassembling the battery module, the clamping member 2 can clamp the box 5 near the battery module being disassembled, preventing the box 5 from deforming during the disassembly process and improving the stability of the battery pack on the base 1, so that other battery modules and the box 5 are not easily affected.

[0065] It should be noted that when disassembling the battery module, first adjust the position of the fixing rod 23 on the base 1 so that the limiting rod 21 is fixed above the box 5 and a channel is reserved for the battery module to pass through. Move the limiting rod 21 along the third direction Z until the clamping part 2 abuts against the edge of the box 5, restricting the movement of the box 5 in the third direction Z. Combine the hooks 31 and lifting tools 32 located on both sides of the battery module, and engage one of the hooks 31 with the corresponding lifting position. Start the lifting equipment so that the lifting rope drives the lifting tool 32 and hook 31 to lift one end of the battery module until it is separated from the box 5. Then engage the other hook 31 with the corresponding lifting position to complete the lifting of the other side of the battery module, so that the battery module is disconnected from the box 5. Then remove the hook 31 from the lifting tool 32 and combine it with the lifting frame 33. Start the lifting equipment again so that the lifting frame 33 lifts the battery module vertically along the third direction Z, completing the disassembly of the battery module.

[0066] It is understandable that the number and location of the hooks 31 can be adjusted according to the installation position of the battery module, which will not be elaborated here.

[0067] See Figure 1 In some embodiments, the battery module disassembly system further includes a leveling section for leveling the connection area.

[0068] In this embodiment, the leveling part is a leveling plate 4, which is adapted to the area to be leveled. A reinforcing rib 41 is fixedly connected to the side of the leveling plate 4 away from the side wall of the box body 5 to enhance the structural strength of the leveling plate 4.

[0069] Thus, since the battery module and the housing 5 are connected by adhesive, after the battery module is hoisted and removed from the housing 5, the flat plate 4 is placed in the connection area of ​​the housing 5 to be leveled. This can level the connection area of ​​the housing 5, preventing the housing 5 from bulging under the action of adhesive during hoisting and affecting the flatness of the housing 5. It also makes it easier to reassemble new battery modules into the leveled connection area of ​​the housing 5, thus improving the stability of the battery pack.

[0070] It is understandable that the plate 4 can also be connected to the limiting rod 21 so that the plate 4 can stably press the connection area of ​​the box 5 to be leveled. The plate 4 can also be connected to the pressing part so that the pressing part can press the plate 4 and make the plate 4 and the connection area of ​​the box 5 to be leveled tightly abut against each other. The setting position and connection method of the plate 4 can be adjusted according to actual needs, as long as it can level the connection area of ​​the box 5 to be leveled. It will not be elaborated here.

[0071] See Figure 1 In some embodiments, the leveling device also includes a handle 42 connected to the leveling plate 4.

[0072] In this embodiment, there are two handles 42, which are fixedly installed at both ends of the flat plate 4 on the side away from the side wall of the box body 5.

[0073] This makes it easier for staff to move the flat plate 4 to the required position, improves the leveling efficiency of the side wall of the box 5, facilitates the assembly of the replaced battery module into the box 5 and further disassemblies other battery modules that need to be disassembled, and improves the stability of the battery pack during the disassembly process.

[0074] Example 2

[0075] In Embodiment 2, the same or corresponding components as in Embodiment 1 are represented by the same reference numerals as in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described.

[0076] In some embodiments, a slider is provided at one end of the fixed rod 23 facing the housing 5, and a groove is provided on the base 1 corresponding to the slider. The groove extends along the first direction X so that the slider can drive the fixed rod 23 to slide along the first direction X. The slider is connected to a fixing pin to limit the position of the slider in the groove.

[0077] This allows staff to easily adjust the position of the fixing rod 23 according to the specifications and dimensions of the battery module, and improves the efficiency of battery module disassembly.
