[0034] In the disassembly of a related battery module, it is necessary to separate the outer shell from the firmly bonded battery modules. Lacking special disassembly tools and using conventional pliers, the biting part with the outer shell is small, and effective force cannot be applied, easily causing damage to the outer shell and making it unable to be reused. Even relying on the operator to operate manually is time-consuming and laborious, and there are certain safety risks. In view of this, the embodiments of the present disclosure provide a disassembly fixture suitable for the outer shell of a battery module.

[0035] The present disclosure provides a disassembly fixture for the outer shell of a battery module, including: a first clamping member and a second clamping member. The first clamping member and the second clamping member intersect and are hinged to each other. An elastic member is provided between the first clamping member and the second clamping member, and the elastic member has a movement tendency that can make the first clamping member and the second clamping member in an open state. Using the disassembly fixture for the outer shell of a battery module provided by the embodiments of the present disclosure, the outer shell of the battery module can be effectively clamped and then peeled off, realizing the rapid disassembly of the battery module.

[0036] Please refer to Figure 1 and Figure 2 , wherein, Figure 1 shows a top view of the disassembly fixture for the outer shell of a battery module in an embodiment of the present disclosure, Figure 2 shows a side view of the disassembly fixture for the outer shell of a battery module in an open state in an embodiment of the present disclosure.

[0037] Combined with Figure 1 and Figure 2 , the disassembly fixture for the outer shell of the battery module may specifically include: a first clamping member and a second clamping member.

[0038] The first clamping member includes a first clamping portion 11, a first holding portion 12, and a first connecting portion 13 located between the first clamping portion 11 and the first holding portion 12.

[0039] The second clamping member includes a second clamping portion 21, a second holding portion 22, and a second connecting portion 23 located between the second clamping portion 21 and the second holding portion 22.

[0040] The first clamping member and the second clamping member can cross each other and are hingedly arranged through the first connecting portion 13 and the second connecting portion 23 to enable opening and closing.

[0041] The opposite ends of the first connecting portion 13 are respectively connected to the first clamping portion 11 and the first holding portion 12. In some embodiments, the first connecting portion 13 has a plurality of connected first bending segments. The opposite ends of the second connecting portion 23 are respectively connected to the second clamping portion 21 and the second holding portion 22. In some embodiments, the second connecting portion 23 has a plurality of connected second bending segments. The plurality of first bending segments in the first connecting portion 13 cross the plurality of second bending segments in the second connecting portion 23 and are hinged at the crossing points to realize the crossing arrangement of the first clamping member and the second clamping member.

[0042] In some embodiments, an articulation hole is correspondingly provided in one first bending segment to be crossed in the first connecting portion 13 and one second bending segment to be crossed in the second connecting portion 23. An articulation member 31 is inserted into the articulation hole, and a clearance fit may be provided between the articulation member 31 and the pin hole. Exemplarily, the articulation member 31 is a rivet. Alternatively, exemplarily, the articulation member 31 is a shaft pin, and a stop member for defining the shaft pin to prevent axial movement of the shaft pin is provided on the side of the free end of the shaft pin. The stop member may be, for example, a strip passing through the free end of the shaft pin or a circlip embedded in the free end of the shaft pin.

[0043] In addition, an elastic member is provided between the first clamping member and the second clamping member, and the elastic member has a movement tendency to cause the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member to be in an open state.

[0044] In some embodiments, the elastic member is arranged between the first connecting portion 13 of the first clamping member and the second connecting portion 23 of the second clamping member. By using the elastic member, the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member can be in an open state without external force applied.

[0045] For example, the elastic member is a compression spring or a reed, and the compression spring or the reed is limited by a limiting member.

[0046] Exemplarily, as Figure 2 shown, the elastic member is a compression spring 41, the limiting member is a pin or rivet 411 connecting the first connecting portion 13 and the second connecting portion 23, and the compression spring 41 is sleeved on the pin or rivet 411. Thus, when the compression spring 41 is in a compressed state, the compression spring 41 generates an outward pushing force to push the first connecting portion 13 of the first clamping member and the second connecting portion 23 of the second clamping member away from each other, so that the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member are in an open state.

[0047] Exemplarily, as Figure 3 shown, the elastic member is a compression spring 41, the limiting member includes a first limiting bump 421 provided on the first connecting portion 13 and a second limiting bump 423 provided on the second connecting portion 23. The first limiting bump 421 is embedded in the first end of the compression spring 41, and the second limiting bump 423 is embedded in the second end of the compression spring 41. Thus, when the compression spring 41 is in a compressed state, the compression spring 41 generates an outward pushing force to push the first connecting portion 13 of the first clamping member and the second connecting portion 23 of the second clamping member away from each other, so that the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member are in an open state.

[0048] Of course, the elastic member and its cooperating limiting member can still be changed in other ways. Exemplarily, the elastic member is a reed, and the limiting member includes a first limiting frame provided on the first connecting portion and a second limiting frame provided on the second connecting portion. The opposite ends of the reed are respectively arranged in the first limiting frame and the second limiting frame.

[0049] It should be noted that in the above description of the elastic member, the elastic member is arranged between the first connecting portion 13 of the first clamping member and the second connecting portion 23 of the second clamping member, but not limited thereto. In some embodiments, the elastic member can be arranged between the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member, or in some embodiments, the elastic member can be arranged between the first holding portion 12 of the first clamping member and the second holding portion 22 of the second clamping member.

[0050] When the disassembly fixture of the battery module housing is to be used, force is applied to the first holding portion 12 of the first clamping member and the second holding portion 22 of the second clamping member. For example, an operator holds the first holding portion 12 of the first clamping member and the second holding portion 22 of the second clamping member with hands and pulls forcefully. For example, the second holding portion 22 of the second clamping member is moved towards the first holding portion 12 of the first clamping member (for example, moved upward). During the movement, through the transmission of the second connecting portion 23, the second clamping portion 21 is driven to rotate around the hinge point and move towards the first clamping portion 11 (for example, moved downward). Thus, a schematic diagram of the clamping state as shown in Figure 4 is formed, and an effective clamping space can be formed between the second clamping portion 21 and the first clamping portion 11 to clamp the battery module housing to be disassembled.

[0051] In some embodiments, the first holding portion 12 and the second holding portion 22 are provided with anti-slip structures. Exemplarily, the anti-slip structure is an anti-slip groove formed in the first holding portion 12 and the second holding portion 22. Exemplarily, the anti-slip structure is an anti-slip coating applied to the surfaces of the first holding portion 12 and the second holding portion 22. Exemplarily, the anti-slip structure is an anti-slip rubber sleeve sleeved on the first holding portion 12 and the second holding portion 22.

[0052] Generally, the battery module housing to be disassembled is a thin metal surface with a certain length and width. Therefore, in the disassembly tool for the battery module housing provided in the embodiments of the present invention, the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member have a relatively wide width, and the width can correspond to the width of the battery module housing to be disassembled.

[0053] The first clamping portion 11 of the first clamping member is a thin flat structure, which is beneficial to penetrate between the battery module housing and the bonded battery module and fit with the battery module housing. Exemplarily, the first clamping portion 11 of the first clamping member is a clamping flat plate. Exemplarily, the first clamping portion 11 of the first clamping member includes a plurality of clamping strips arranged in parallel along the width direction, and the plurality of clamping strips can be arranged at equal intervals or unequal intervals, and the plurality of clamping strips are connected to the first connecting portion 13 of the first clamping member.

[0054] In some embodiments, the open end of the clamping flat plate or the clamping strip is provided with a wedge-shaped or ramp-shaped guiding portion. In Figure 5In the illustrated embodiment, an introduction portion 110 is provided at the open end of the clamping flat plate or clamping strip of the first clamping portion 11 of the first clamping member. The introduction portion 110 is in the shape of a wedge or a slope and has a free end that is thinner than the clamping flat plate or clamping strip itself. With the aid of the introduction portion 110, it is more conducive for the first clamping portion 11 of the first clamping member to penetrate into the gap between the battery module housing to be disassembled and the plurality of battery modules bonded thereto. Only when there is partial detachment between the battery module housing to be disassembled and the battery modules and a gap is exposed, can the introduction portion 110 penetrate therebetween. In addition, after the introduction portion 110 penetrates into the gap between the battery module housing and the battery modules, it is more smooth to then insert the first clamping portion 11 of the entire first clamping member along the trend. At this time, the introduction portion 110 can also cut the adhesive between the battery module housing and the battery modules to release the bonding between the battery module housing and the plurality of battery modules.

[0055] The second clamping portion 21 of the second clamping member can move away from or close to the first clamping portion 11 of the first clamping member under the application of force. The second clamping portion 21 of the second clamping member can have a relatively thick thickness to provide the required structural strength.

[0056] In some embodiments, such as Figure 1 shown, the second clamping portion 21 of the second clamping member includes a plurality of clamping ribs 210 arranged in parallel along the width direction. The plurality of clamping ribs 210 can be arranged at equal or unequal intervals, and each clamping rib 210 is connected to the second connecting portion 23 of the second clamping member. Exemplarily, each clamping rib 210 can be designed with a strengthening structure, such as providing reinforcing ribs on the clamping rib 210 or thickening the thickness, to enhance the clamping strength.

[0057] To enable the first clamping portion 11 of the first clamping member and the second clamping portion 21 of the second clamping member to more firmly clamp the battery module housing to be disassembled, in some embodiments, engaging teeth are provided on the first clamping surface of the first clamping portion 11 of the first clamping member and the second clamping surface of the second clamping portion 21 of the second clamping member. In the embodiment as Figure 6 shown, a first engaging tooth 111 can be provided on the first clamping surface of the first clamping portion 11 of the first clamping member, and a second engaging tooth 211 can be provided on the second clamping surface of the second clamping portion 21 of the second clamping member. The first engaging tooth 111 can cooperate with the second engaging tooth 211 to have a powerful biting force.

[0058] When applying the disassembly fixture for the battery module housing provided by the present disclosure, such as Figure 7As shown in the figure, first, separate the outer shell 51 of the battery module to be disassembled from the bonded battery module 52 to form an opening. Then, insert the open end of the first clamping part 11 of the first clamping member in the disassembly jig into the gap between the outer shell 51 of the battery module to be disassembled and the battery module 52. After continuing to insert it for a certain distance, operate the first holding part 12 of the first clamping member and the second holding part 22 of the second clamping member, so that the second clamping part 21 of the second clamping member approaches the first clamping part 11 of the first clamping member, and firmly clamp the outer shell 51 of the battery module to be disassembled by the first clamping part 11 and the second clamping part 21. Then, while continuing to apply force to the first holding part 12 and the second holding part 22 to make the first clamping part 11 and the second clamping part 21 clamp the outer shell 51 of the battery module to be disassembled, pull the disassembly jig forcefully, so that the clamped outer shell 51 of the battery module to be disassembled is gradually and completely separated from the battery module 52, and the disassembly is completed.

[0059] The disassembly jig for the outer shell of the battery module provided by the present disclosure includes: a first clamping member, including a first clamping part, a first holding part, and a first connecting part located between the first clamping part and the first holding part; a second clamping member, including a second clamping part, a second holding part, and a second connecting part located between the second clamping part and the second holding part; the first clamping member and the second clamping member are arranged in a mutually crossed and hinged manner through the first clamping part and the second clamping part, and an elastic member is provided between the first clamping member and the second clamping member, and the elastic member has a movement tendency that can make the first clamping part of the first clamping member and the second clamping part of the second clamping member be in an open state. By using the disassembly jig for the outer shell of the battery module provided by the embodiments of the present disclosure, the outer shell of the battery module can be effectively clamped and then peeled off, realizing the rapid disassembly of the battery module.

[0060] The above embodiments are only illustrative of the principles and effects of the present disclosure, rather than limiting the present disclosure. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present disclosure should still be covered by the protection scope of the present disclosure.
