[0036] In the disassembly of a related battery module, to separate the outer shell from the firmly bonded battery module, 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 clamping device suitable for the outer shell of a battery module.

[0037] The present disclosure provides a clamping device for a battery module shell, comprising: a first clamping arm, a second clamping arm, a first elastic member, and a second elastic member, wherein the first clamping arm and the second clamping arm intersect each other through a through-portion and form a rotation fulcrum, the first elastic member is disposed between the second connecting portion in the through-portion and the inner wall of the through-portion of the first clamping arm, and is used to provide a first elastic force forming a first movement trend, and the second elastic member is disposed between the first clamping arm and the second clamping arm, and is used to provide a second elastic force forming a second movement trend opposite to the first movement trend. The clamping device for a battery module shell provided by the embodiment of the present disclosure can effectively clamp the battery module shell and then peel it off, thereby realizing rapid disassembly of the battery module.

[0038] See also Figure 1 and Figure 2 ,in, Figure 1 Shown is a top view of a clamping device for a battery module housing in one embodiment of the present disclosure, Figure 2 Shown is a side view of a battery module housing in an open state in an embodiment of the present disclosure.

[0039] Combination Figure 1 and Figure 2 The clamping device of the battery module housing may specifically include: a first clamping arm, a second clamping arm, a first elastic member, and a second elastic member.

[0040] The first clamp arm includes a first clamp body 11 , a first operating end 12 , and a first connecting portion 13 located between the first clamp body 11 and the first operating end 12 . The first connecting portion 13 is provided with a through portion (not shown in the figure).

[0041] The second clamp arm includes a second clamp body 21, a second operating end 22, and a second connecting portion 23 located between the second clamp body 21 and the second operating end 22. The second connecting portion 23 is restricted to penetrate the through-portion of the first clamp arm, so that the first clamp arm and the second clamp arm intersect with each other. The second connecting portion 23 is restricted to penetrate the through-portion, and the size of the through-portion is slightly larger than the through-portion of the second connecting portion, so as to provide the second connecting portion with a moving space in the through-portion. For example, the size of the through-portion in the clamping direction is larger than the through-portion of the second connecting portion, so as to provide the second connecting portion with a corresponding movement in the through-portion along the clamping direction. The clamping direction is the direction in which the first clamp body 11 and the second clamp body 21 approach or move away from each other, that is, Figure 2 The up and down directions in .

[0042] The opposite ends of the first connecting portion 13 are respectively connected to the first clamping body 11 and the first operating end 12. In some embodiments, the first connecting portion 13 has a plurality of connected first bending segments, wherein the first bending segments can be horizontal straight segments, vertical straight segments, inclined straight segments, or curved segments. The opposite ends of the second connecting portion 23 are respectively connected to the second clamping body 21 and the second operating end 22. In some embodiments, the second connecting portion 23 has a plurality of connected second bending segments, wherein the second bending segments can be horizontal straight segments, vertical straight segments, inclined straight segments, or curved segments. Continuing as Figure 2 shown, a through portion can be formed in one of the plurality of first bending segments of the first connecting portion 13, and one of the plurality of second bending segments of the second connecting portion 23 is inserted into the through portion with a restricted insertion position to achieve the crossed arrangement of the first clamping arm and the second clamping arm.

[0043] In some embodiments, the through portion can be, for example, a through hole into which the second bending segment of the second connecting portion 23 is inserted. In some embodiments, the through portion can be, for example, a through hole with an opening. During installation, the opening of the through hole is opened, the second bending segment of the second connecting portion 23 is inserted through the opening, and then the opening of the through hole is closed. In some embodiments, the through portion is a through groove, and the second bending segment of the second connecting portion 23 is inserted through the notch of the through groove.

[0044] In addition, a first elastic member and a second elastic member are provided between the first clamping arm and the second clamping arm. The first elastic member and the second elastic member cooperate with each other and have a movement tendency to keep the first clamping body 11 of the first clamping arm and the second clamping body 21 of the second clamping arm open.

[0045] The first elastic member abuts between the second connecting portion of the second clamping arm within the through portion and the inner wall of the through portion of the first clamping arm, so that the second clamping arm abuts against the first clamping arm to form a rotation fulcrum therebetween, for providing a first elastic force for the first movement tendency of approaching or separating between the first clamping body and the second clamping body.

[0046] Correspondingly, the second elastic member is provided between the first clamping arm and the second clamping arm, for providing a second elastic force for forming a second movement tendency opposite to the first movement tendency.

[0047] In some embodiments, the first elastic member and the second elastic member are located on the same side of the rotation. In some embodiments, the first elastic member and the second elastic member are respectively located on opposite sides of the rotation fulcrum. In some embodiments, the first elastic force provided by the first elastic member may be an elastic thrust or an elastic tensile force. For example, the first elastic member is a first compression spring or a first tension spring. In some embodiments, the second elastic force provided by the second elastic member may be an elastic thrust or an elastic tensile force. For example, the second elastic member is a second compression spring or a second tension spring. Thus, different cooperation combinations are achieved through the selection of the installation positions of the first elastic member and the second elastic member and the selection of elastic thrust and elastic tensile force, which will not be elaborated here.

[0048] In addition, the first elastic member is limited by a first limiting member. In some embodiments, the first limiting member is a plug, a rivet, a limiting strip, or a limiting post. The second elastic member is limited by a second limiting member. In some embodiments, the second limiting member is a plug, a rivet, a limiting strip, or a limiting post.

[0049] Exemplarily, as Figure 2 shown, the first elastic member abuts between the second connecting portion 23 of the second clamping arm within the through portion and the inner wall of the through portion of the first clamping arm, so that the second clamping arm abuts against the first clamping arm to form a rotation fulcrum 310 therebetween. The first elastic member is implemented as a first compression spring 31. The first elastic member is limited by a first limiting member. The first limiting member is implemented as a limiting post 411 connecting the first connecting portion 13 and the second connecting portion 23. The first compression spring 31 is sleeved on the limiting post 411. Thus, when the first compression spring 31 is in a compressed state, the first compression spring 31 generates an outward first ejecting force to push the first connecting portion 13 of the first clamping arm and the second connecting portion 23 of the second clamping arm away from each other.

[0050] Correspondingly, as Figure 2 shown, the second elastic member is disposed between the first connecting portion of the first clamping arm and the second connecting portion of the second clamping arm, and is used to provide a second elastic force that forms a second movement trend opposite to the first movement trend. The second elastic member is implemented as a second compression spring 41. The second elastic member is limited by a second limiting member. The second limiting member is implemented as a plug or a rivet 411 connecting the first connecting portion 13 and the second connecting portion 23. The second compression spring 41 is sleeved on the plug or the rivet 411. Thus, when the second compression spring 41 is in a compressed state, the second compression spring 41 generates an outward second ejecting force to push the first connecting portion 13 of the first clamping arm and the second connecting portion 23 of the second clamping arm away from each other.

[0051] Through the interaction of the first outward ejecting force generated by the first compression spring 31 and the second outward ejecting force generated by the second compression spring 41, the first clamping body of the first clamping arm and the second clamping body of the second clamping arm can be in a movement trend of opening. For example, as Figure 2 described, the first clamping body 11 of the first clamping arm and the second clamping body 21 of the second clamping arm can be in an open state of maintaining balance relative to the rotation fulcrum 310.

[0052] It should be noted that in the above description of the first elastic member and the second elastic member, the first elastic member and the second elastic member are arranged between the first connecting portion 13 of the first clamping arm and the second connecting portion 23 of the second clamping arm, but not limited thereto. In some embodiments, the first elastic member and / or the second elastic member can be arranged between the first clamping body 11 of the first clamping arm and the second clamping body 21 of the second clamping arm. Or, in some embodiments, the first elastic member and / or the second elastic member can be arranged between the first operating end 12 of the first clamping arm and the second operating end 22 of the second clamping arm.

[0053] When the clamping device of the battery module housing is to be used, by applying a force on the first operating end 12 of the first clamping arm and the second operating end 22 of the second clamping arm. For example, an operator holds the first operating end 12 of the first clamping arm and the second operating end 22 of the second clamping arm with a hand and pulls forcefully. For example, the second operating end 22 of the second clamping arm is moved around the rotation fulcrum 310 towards the first operating end 12 of the first clamping arm (for example, moving upward). During the movement, through the transmission of the second connecting portion 23, the second clamping body 21 is driven to rotate around the rotation fulcrum 310 and move towards the first clamping body 11 (for example, moving downward). Thus, a schematic diagram of the clamping state as shown in Figure 4 is formed, and the second clamping body 21 and the first clamping body 11 can form an effective clamping space and clamp the battery module housing to be disassembled.

[0054] In some embodiments, the first operating end 12 and the second operating end 22 are provided with an anti-slip structure. Exemplarily, the anti-slip structure is an anti-slip groove opened on the first operating end 12 and the second operating end 22. Exemplarily, the anti-slip structure is an anti-slip coating applied to the surfaces of the first operating end 12 and the second operating end 22. Exemplarily, the anti-slip structure is an anti-slip rubber sleeve sleeved on the first operating end 12 and the second operating end 22.

[0055] Generally, the outer shell of the battery module to be disassembled is a thin metal surface, which has a certain length and width. Therefore, in the disassembly tool for the outer shell of the battery module provided in the embodiments of the present invention, the first clamping body 11 of the first clamping arm and the second clamping body 21 of the second clamping arm have a relatively wide width, and the width can correspond to the width of the outer shell of the battery module to be disassembled.

[0056] The first clamping body 11 of the first clamping arm is a thin flat structure, which is beneficial to penetrate between the outer shell of the battery module and the bonded battery module and fit with the outer shell of the battery module. Exemplarily, the first clamping body 11 of the first clamping arm is a clamping flat plate. Exemplarily, the first clamping body 11 of the first clamping arm 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 arm.

[0057] In some embodiments, a guiding portion in the shape of a wedge or a slope is provided at the open end of the clamping flat plate or the clamping strip. In the embodiment as Figure 5 shown, as the clamping flat plate or the clamping strip at the open end of the first clamping body 11 of the first clamping arm, a guiding portion 110 is provided, and the guiding portion 110 is in the shape of a wedge or a slope and has a free end thinner than the clamping flat plate or the clamping strip itself. With the help of the guiding portion 110, it is more beneficial for the first clamping body 11 of the first clamping arm to penetrate into the gap between the outer shell of the battery module to be disassembled and the plurality of bonded battery modules. Only when there is partial detachment between the outer shell of the battery module to be disassembled and the battery module and a gap is exposed, can the guiding portion 110 penetrate therebetween. In addition, after the guiding portion 110 penetrates into the gap between the outer shell of the battery module and the battery module, the entire first clamping body 11 of the first clamping arm can be inserted more smoothly subsequently. At this time, the guiding portion 110 can also cut the bonding glue between the outer shell of the battery module and the battery module to release the bonding between the outer shell of the battery module and the plurality of battery modules.

[0058] The second clamping body 21 of the second clamping arm can move away from or close to the first clamping body 11 of the first clamping arm under the condition of applying force, and the second clamping body 21 of the second clamping arm can have a relatively thick thickness to provide the required structural strength.

[0059] In some embodiments, as Figure 1 shown, the second clamping body 21 of the second clamping arm includes a plurality of clamping ribs 210 arranged in parallel along the width direction, and the plurality of clamping ribs 210 can be arranged at equal intervals or unequal intervals, and each clamping rib 210 is connected to the second connecting portion 23 of the second clamping arm. Exemplarily, each clamping rib 210 can be designed with a strengthening structure, such as providing a reinforcing rib on the clamping rib 210 or thickening the thickness, which can enhance the clamping strength.

[0060] In some embodiments, in order to make the first clamping body 11 of the first clamping arm and the second clamping body 21 of the second clamping arm cooperate to more firmly clamp the battery module housing to be disassembled, engaging teeth are provided on the first clamping surface of the first clamping body 11 in the first clamping arm and the second clamping surface of the second clamping body 21 in the second clamping arm. As Figure 6 shown in the embodiment, a first engaging tooth 111 can be provided on the first clamping surface of the first clamping body 11 in the first clamping arm, and a second engaging tooth 211 can be provided on the second clamping surface of the second clamping body 21 in the second clamping arm. The first engaging tooth 111 can cooperate with the second engaging tooth 211 to have a strong biting force.

[0061] When applying the clamping device for the battery module housing provided by the present disclosure, as Figure 7 shown, first, separate the battery module housing 51 to be disassembled from the bonded battery module 52 to form an opening gap. Then, insert the open end of the first clamping body 11 of the first clamping arm in the clamping device into the opening gap between the battery module housing 51 to be disassembled and the battery module 52. After continuing to insert it for a certain distance, operate the first operating end 12 of the first clamping arm and the second operating end 22 of the second clamping arm, so that the second clamping body 21 of the second clamping arm rotates around the rotation fulcrum 310 under the action of the first elastic member (such as the first compression spring 311) and the second elastic member (such as the second compression spring 411) to approach the first clamping body 11 of the first clamping arm. The battery module housing 51 to be disassembled is firmly clamped by the first clamping body 11 and the second clamping body 21. Then, while continuing to apply force to the first operating end 12 and the second operating end 22 to make the first clamping body 11 and the second clamping body 21 clamp the battery module housing 51 to be disassembled, pull the clamping device forcefully, so that the clamped battery module housing 51 to be disassembled is gradually and completely separated from the battery module 52, completing the disassembly.

By utilizing the clamping device for the battery module shell provided in the embodiment of the present disclosure, through the cooperation of the first operating end and the second operating end, and utilizing the first elastic member and the second elastic member, the first clamping member and the second clamping member can cooperate with each other to rotate with the rotating fulcrum to effectively clamp the battery module shell and peel it off, thereby realizing rapid disassembly of the battery module.

[0063] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure.
