[0003] In view of the above problems, the present application provides a limiting device and a battery production system, which can improve the compatibility of the limiting device and can be compatible with battery cells of various specifications.

[0004] In a first aspect, the present application provides a limiting device, comprising:

[0005] Base member;

[0006] A first clamping assembly and a second clamping assembly, the first clamping assembly and the second clamping assembly are arranged on the same side of the base component along the first direction, the first clamping assembly is connected to the base component, the first clamping assembly and the second clamping assembly are used to clamp the object together along the second direction, and the relative positions of the two along the second direction are adjustable, the second clamping assembly includes two first limiting mechanisms, the two first limiting mechanisms are arranged at intervals along the third direction, and the relative positions along the third direction are adjustable, the two first limiting mechanisms are used to clamp the object together along the third direction, the second direction and the third direction are respectively perpendicular to the first direction, and the second direction and the third direction intersect.

[0007] The object clamped by the first clamping assembly and the second clamping assembly can be a battery cell. The spacing between the first clamping assembly and the second clamping assembly along the second direction is adjustable, and battery cells of different sizes along the second direction can be clamped. The spacing between the two first limiting mechanisms of the second clamping assembly along the third direction is adjustable, and battery cells of different sizes along the third direction can be clamped, so that the limiting device can clamp and limit battery cells of different sizes to improve the compatibility of the limiting device.

[0008] In some embodiments, the first clamping assembly includes a first abutment assembly, the first limiting mechanism includes a second abutment assembly, the second abutment assemblies of the two first limiting mechanisms are used to jointly clamp the object in the third direction, the first abutment assembly and the second abutment assembly form a clamping unit, and the clamping unit is used to jointly clamp the object along the second direction.

[0009] Thus, by clamping and limiting multiple positions of the object through the first abutting assembly and the second abutting assembly, the battery cell can be clamped and fixed more reliably.

[0010] In some embodiments, the first abutment assembly includes a first abutment member and a second abutment member, the first abutment member and the second abutment member are spaced apart along the third direction, and the second abutment assembly is respectively provided on both sides of the first abutment assembly along the third direction.

[0011] By having the first limiting members of the two first limiting mechanisms abut against one side of the battery cell along the second direction, and the first abutting member and the second abutting member abut against the other side of the battery cell along the second direction, the battery cell can be clamped and fixed along the second direction. By adjusting the second limiting members of the two first limiting mechanisms toward each other, the battery cell can be clamped and fixed along the third direction to accommodate battery cells of different sizes, thereby improving the compatibility of the limiting device.

[0012] In some embodiments, the first abutment member includes a main body and an abutment portion, the main body is connected to the abutment portion at one end along the second direction, the abutment portion is used to abut against the object along the second direction, the second abutment member includes an abutment member and a support member, the support member is provided on at least one side of the abutment member along the second direction, and the support member and the main body are used to jointly support the object.

[0013] Therefore, the battery cell can be limited and supported by the first abutting member and the second abutting member.

[0014] In some embodiments, the second abutment assembly includes a third abutment member and a fourth abutment member, the third abutment member is provided with a fourth abutment member on one side along the second direction, the third abutment member and the first abutment assembly are used to jointly clamp the object along the second direction, and the fourth abutment members of the two first limiting mechanisms are used to jointly clamp the object along the third direction.

[0015] Thus, it is possible to achieve that the two second abutting components clamp the object along the third direction, and clamp the object together with the first abutting component along the second direction.

[0016] In some embodiments, there are multiple clamping units, and the multiple clamping units are arranged along the second direction. Thus, multiple battery cells can be clamped and fixed by the multiple clamping units to meet the production requirements of battery cells of different specifications.

[0017] In some embodiments, the first clamping assembly also includes a first connecting assembly, a first one of the first abutting member and the second abutting member is connected to the first connecting assembly, a second one of the first abutting member and the second abutting member is connected to the base member, the first connecting assembly is connected to the base member in an adjustable manner along a third direction, one of the two first limiting mechanisms is located on the side of the first connecting assembly away from the base member and is connected to the first connecting assembly, and the positions of the two first limiting mechanisms relative to the first clamping assembly along the second direction are adjustable.

[0018] Therefore, when the first connecting component is in an unlocked state, the first connecting component is adjusted to move relative to the base component, so that the two first limiting mechanisms move toward each other or away from each other along the third direction, so as to realize the position of the two first limiting mechanisms along the third direction, so as to clamp objects of different sizes along the third direction, and the position of the two first limiting mechanisms relative to the first clamping component along the second direction is adjustable, so that the limiting device can clamp objects of different sizes along the second direction, so as to improve the compatibility of the limiting device.

[0019] In some embodiments, the first connection component includes:

[0020] A first connecting member connected to the first member and slidably connected to the base member along a third direction;

[0021] The first locking mechanism is arranged on the first connecting member, and a plurality of first clamping grooves are provided on the side of the base member facing the first limiting mechanism. The plurality of first clamping grooves are arranged along a third direction. The first locking mechanism has a first clamping portion, and the first clamping portion can move relative to the first connecting member along the first direction, and at least part of the first clamping portion can move into or out of the first clamping groove along the first direction.

[0022] The first clamping portion moves away from the first clamping groove along the first direction to release the locked state, so that the first connecting member can slide relative to the base member, and the spacing between the two first limiting mechanisms can be adjusted so that the two first limiting mechanisms can clamp battery cells of different sizes along the third direction. The first clamping member is then moved toward the first clamping groove along the first direction to clamp the first clamping member with the first clamping groove to facilitate the fixation of the first limiting mechanism, thereby allowing the two first limiting mechanisms to clamp the battery cell.

[0023] In some embodiments, the first locking mechanism comprises:

[0024] A first clamping connector, slidably connected to the first connector along a first direction;

[0025] The first clamping member is located between the first connecting member and the base component and is connected to the first clamping connecting member. The end of the first clamping member facing the base component forms a first clamping portion.

[0026] Therefore, by moving the first snap-fit ​​connector, the first snap-fit ​​connector and the first snap-fit ​​groove can be snapped into or out of the first snap-fit ​​groove to achieve locking and unlocking of the first connector and the base component, thereby achieving adjustment and fixation of the first limiting mechanism relative to the base component along the third direction.

[0027] In some embodiments, the first locking mechanism further comprises:

[0028] The first elastic member, one end of the first elastic member abuts against the first clamping member, and the other end of the first elastic member abuts against the first connecting member, and the elastic force of the first elastic member has a tendency to move the first clamping member toward the first clamping groove.

[0029] Therefore, under the elastic force of the first elastic member, the squeezing force between the first clamping member and the first clamping groove can be increased, thereby improving the reliability of the locking connection between the first connecting member and the base component.

[0030] In some embodiments, the first limiting mechanism also includes a second connecting component, which is located on the side of the second abutment component facing the base component and is connected to the second abutment component. One of the second connecting components in the two first limiting mechanisms is connected to the base component, and the other second connecting component is located on the side of the first connecting component away from the base component and is connected to the first connecting component. The second connecting component has a locked state relatively fixed with the first clamping component and an unlocked state movable along the second direction relative to the first clamping component.

[0031] Thus, by unlocking and locking the second connecting assembly, the relative position of the second abutting assembly and the first abutting assembly along the second direction can be adjusted and fixed, so that the second abutting assemblies of the two first limiting mechanisms abut against the same side of the battery cell.

[0032] In some embodiments, the base member and the first connecting assembly are respectively provided with a plurality of second snap-fit ​​grooves on one side facing the first limiting mechanism, and the plurality of second snap-fit ​​grooves are arranged along the second direction, and the second connecting assembly includes:

[0033] A second connecting member, the second connecting member is located on a side of the abutting assembly facing the base member and connected to the abutting assembly, the second connecting member in one second connecting assembly is slidably connected to the base member along a second direction, and the second connecting member in another second connecting assembly is located on a side of the first connecting assembly facing away from the base member and is slidably connected to the first connecting assembly along the second direction;

[0034] The second locking mechanism is arranged on the second connecting member, and the second locking mechanism has a second clamping portion, which can move relative to the first member along the first direction, and at least part of the second clamping portion can move into or out of the second clamping groove along the first direction.

[0035] Thus, by unlocking and locking the second locking mechanism, it is possible to achieve movement and fixation of a first limiting mechanism relative to the base component along the second direction, and movement and fixation of another first limiting mechanism relative to the first connecting component along the second direction, thereby achieving movement of the second abutment components of the two second limiting components with the first abutment components along the second direction, so that battery cells of different sizes can be clamped along the second direction; at the same time, adjusting the first connecting component so that the first connecting component moves relative to the base component along the third direction can change the relative positions of the second abutment components in the two second limiting components, so that battery cells of different sizes can be clamped along the third direction, thereby improving the compatibility of the limiting device.

[0036] In some embodiments, the second locking mechanism comprises:

[0037] A second clamping connector is slidably connected to the second connector along a first direction;

[0038] The second clamping member is located on the side of the second clamping connector facing the base component and is connected to the second clamping connector. The end of the second clamping member facing the base component forms a second clamping portion.

[0039] Therefore, by moving the second snap-fit ​​connector, the second snap-fit ​​connector and the second snap-fit ​​groove can be snapped into or disengaged from the second snap-fit ​​groove to achieve locking and unlocking of the second connector and the above-mentioned first one, thereby achieving adjustment of the relative position of the second abutment component in the two second limiting components along the second direction with the first abutment component, and locking and fixing of the second abutment component.

[0040] In some embodiments, the second locking mechanism further comprises:

[0041] The second elastic member, one end of the second elastic member abuts against the second clamping member, and the other end of the second elastic member abuts against the second connecting member, and the elastic force of the second elastic member has a tendency to move the second clamping member toward the second clamping groove.

[0042] Therefore, under the elastic force of the second elastic member, the squeezing force between the second clamping member and the second clamping groove can be increased, thereby improving the reliability of the locking.

[0043] In a second aspect, the present application provides a battery production system, comprising the limiting device of the first aspect, wherein the object is a battery cell.

[0044] Since the battery production system includes all the technical features of the limiting device of the first aspect mentioned above, the effects are the same as those mentioned above and will not be repeated here.

[0070] During the battery production process, the limiting device for conveying battery cells clamps and limits the battery cells through multiple limiting blocks, and is only compatible with one specification of battery cells, resulting in poor compatibility. Specifically, limiting blocks are provided around each battery cell, which are fixed to the base or tray by screws, and the battery cells are transported by the limiting device to achieve different manufacturing processes. Due to the variety of specifications of battery cells, the same limiting device is difficult to be compatible with battery cells of various specifications, and the limiting device has the problem of poor compatibility.

[0071] In view of this, the present application provides a limiting device, wherein the objects clamped by the first clamping assembly and the second clamping assembly can be battery cells, the spacing between the first clamping assembly and the second clamping assembly along the second direction is adjustable, and battery cells of different sizes along the second direction can be clamped, and the spacing between the two first limiting mechanisms of the second clamping assembly along the third direction is adjustable, and battery cells of different sizes along the third direction can be clamped, so that the limiting device can clamp and limit battery cells of different sizes to improve the compatibility of the limiting device.

[0072] The object clamped by the limiting device of the present application may be, but is not limited to, a battery cell or other square objects.

[0073] For the convenience of explanation, please refer to the following examples. Figure 1-Figure 5 , a limiting device 1000 of some embodiments of the present application is taken as an example for description.

[0074] The limiting device 1000 includes a base member 100, a first clamping assembly 200 and a second clamping assembly 300. The first clamping assembly 200 and the second clamping assembly 300 are arranged on the same side of the base member 100 along the first direction X, the first clamping assembly 200 is connected to the base member 100, the first clamping assembly 200 and the second clamping assembly 300 are used to clamp an object together along the second direction Y, and the relative position of the two along the second direction Y is adjustable, the second clamping assembly 300 includes two first limiting mechanisms 310, the two first limiting mechanisms 310 are arranged at intervals along the third direction Z, and the relative position along the third direction Z is adjustable, the two first limiting mechanisms 310 are used to clamp an object together along the third direction Z, the second direction Y and the third direction Z are respectively perpendicular to the first direction X, and the second direction Y and the third direction Z are arranged at an angle.

[0075] The object may be, but is not limited to, a battery cell.

[0076] Optionally, the second direction Y and the third direction Z may be perpendicular.

[0077] Optionally, the base member 100 may be substantially a plate-shaped structure but is not limited thereto.

[0078] The relative position of the first clamping assembly 200 and the second clamping assembly 300 along the second direction Y is adjustable, which means that one of the first clamping assembly 200 and the second clamping assembly 300 has a locked state relatively fixed relative to the other, and an unlocked state in which one can move along the second direction Y relative to the other.

[0079] The adjustable relative position of the two first limiting mechanisms 310 along the third direction Z refers to a locked state in which one of the two first limiting mechanisms 310 is relatively fixed relative to the other, and an unlocked state in which one can move along the third direction Z relative to the other.

[0080] Exemplarily, the first clamping assembly 200 and the second clamping assembly 300 are both connected to the base member 100 by bolts. Specifically, optionally, the base member 100 is provided with a first long slot hole, the length direction of the first long slot hole is the same as the second direction Y, the second limit assembly is provided with a second long slot hole, the length direction of the second long slot hole is the same as the third direction Z, the bolt passes through the first long slot hole and the second long slot hole, and fixes the second limit assembly to the base member 100, when the bolt is loosened, the second limit assembly can move relative to the base member 100 along the second direction Y and the third direction Z, so as to realize the movement of the second clamping assembly 300 relative to the first clamping assembly 200 along the second direction Y, and the relative movement of the two second limit assemblies along the third direction Z.

[0081] The object clamped by the first clamping assembly 200 and the second clamping assembly 300 can be a battery cell. The spacing between the first clamping assembly 200 and the second clamping assembly 300 along the second direction Y is adjustable, and battery cells of different sizes along the second direction Y can be clamped. The spacing between the two first limiting mechanisms 310 of the second clamping assembly 300 along the third direction Z is adjustable, and battery cells of different sizes along the third direction Z can be clamped, so that the limiting device 1000 can clamp and limit battery cells of different sizes to improve the compatibility of the limiting device 1000.

[0082] In some embodiments, please refer to Figure 1 and Figure 2 The first clamping assembly 200 includes a first abutment assembly 210, and the first limiting mechanism 310 includes a second abutment assembly 311. The second abutment assemblies 311 of the two first limiting mechanisms 310 are used to clamp the object together in the third direction Z. The first abutment assembly 210 and the second abutment assembly 311 form a clamping unit, and the clamping unit is used to clamp the object together along the second direction Y.

[0083] Thus, by clamping and limiting multiple positions of the object through the first abutting assembly 210 and the second abutting assembly 311 , the battery cell can be clamped and fixed more reliably.

[0084] In some embodiments, please refer to Figure 1and Figure 2 The first abutting assembly 210 includes a first abutting member 211 and a second abutting member 212 , the first abutting member 211 and the second abutting member 212 are arranged at intervals along the third direction Z, and the second abutting assembly 311 is respectively provided on both sides of the first abutting assembly 210 along the third direction Z.

[0085] Optionally, the first abutting member 211 and the base member 100 may be connected by bolts, the first abutting member 211 may also be arranged on the base member 100 by welding or riveting, and the second abutting member 212 is arranged on the base member 100 in an adjustable manner along the third direction Z. Alternatively, the first abutting member 211 is arranged on the base member 100 in an adjustable manner along the third direction Z, and the first abutting member 211 is arranged on the base member 100 by bolts, welding or riveting, so as to increase the clamping range of the two second limit assemblies along the third direction Z.

[0086] The number of the first abutting member 211 may be one or more.

[0087] The number of the second abutting member 212 may be one or more.

[0088] By having the first limiting members of the two first limiting mechanisms 310 abut against one side of the battery cell along the second direction Y, and the first abutting member 211 and the second abutting member 212 abut against the other side of the battery cell along the second direction Y, the battery cell can be clamped and fixed along the second direction Y. Then, by having the second limiting members of the two first limiting mechanisms 310 adjusted toward each other, the battery cell can be clamped and fixed along the third direction Z to accommodate battery cells of different sizes, thereby improving the compatibility of the limiting device 1000.

[0089] In some embodiments, please refer to Figure 1 and Figure 2 The first abutment member 211 includes a main body 2111 and an abutment portion 2112. One end of the main body 2111 along the second direction Y is connected to the abutment portion 2112. The abutment portion 2112 is used to abut against an object along the second direction Y. The second abutment member 212 includes an abutment piece 2121 and a support piece 2122. The support piece 2122 is provided on at least one side of the second abutment member along the second direction Y. The support piece 2122 and the main body 2111 are used to jointly support an object.

[0090] Optionally, the main body portion 2111 and the abutting portion 2112 may be an integrally formed structure or a separate structure.

[0091] Optionally, the abutment member 2121 and the support member 2122 may be an integrally formed structure or a separate structure.

[0092] Optionally, part of the abutment portion 2112 protrudes from the main body portion 2111 along the direction from the first abutment member 211 to the second abutment member 212 , and part of the abutment piece 2121 protrudes from the support piece 2122 along the direction from the second abutment member 212 to the first abutment member 211 .

[0093] Therefore, the first abutting member 211 and the second abutting member 212 can be used to limit and support the battery cell.

[0094] In some embodiments, the second abutment assembly 311 includes a third abutment member 3111 and a fourth abutment member 3112. The third abutment member 3111 is provided with a fourth abutment member 3112 on one side along the second direction Y. The third abutment member 3111 and the first abutment assembly 210 are used to jointly clamp the object along the second direction Y. The fourth abutment members 3112 of the two first limiting mechanisms 310 are used to jointly clamp the object along the third direction Z.

[0095] Optionally, the third abutting member 3111 and the fourth abutting member 3112 may be an integrated structure or a separate structure.

[0096] Optionally, the third abutting member 3111 in the two first position limiting mechanisms 310 is located between the fourth abutting members 3112 of the two first position limiting mechanisms 310 along the third direction Z. Alternatively, a portion of the third abutting member 3111 in the two first position limiting mechanisms 310 is located between the fourth abutting members 3112 of the two first position limiting mechanisms 310 along the third direction Z.

[0097] Thus, the two second abutting components 311 can clamp the object along the third direction Z, and can clamp the object together with the first abutting component 210 along the second direction Y.

[0098] In some embodiments, please refer to Figure 1 and Figure 2 There are multiple clamping units, and the multiple clamping units are arranged along the second direction Y. Therefore, multiple battery cells can be clamped and fixed by the multiple clamping units to meet the production requirements of battery cells of different specifications.

[0099] In some embodiments, please refer to Figure 1 and Figure 2The first clamping assembly 200 also includes a first connecting assembly 220, a first one of the first abutting member 211 and the second abutting member 212 is connected to the first connecting assembly 220, and a second one of the first abutting member 211 and the second abutting member 212 is connected to the base member 100, and the first connecting assembly 220 is connected to the base member 100 in an adjustable manner along the third direction Z, one of the two first limiting mechanisms 310 is located on the side of the first connecting assembly 220 away from the base member 100, and is connected to the first connecting assembly 220 in an adjustable manner along the second direction Y, and the other one of the two first limiting mechanisms 310 is connected to the base member 100 in an adjustable manner along the second direction Y.

[0100] The first and the second are different ones of the first abutting member 211 and the second abutting member 212. For example, the first is the first abutting member 211 and the second is the second abutting member 212; or the first is the second abutting member 212 and the second is the first abutting member 211.

[0101] Optionally, the second one of the first abutting member 211 and the second abutting member 212 is connected to the base member 100 by methods including but not limited to screw connection, riveting, welding or integral molding.

[0102] The connection between the first connecting component 220 and the base member 100 may be, but is not limited to, a bolt connection. For example, a third long slot hole is provided on one side of the base member 100 facing the first connecting component 220, and the length direction of the third long slot hole is the same as the third direction Z. The first connecting component 220 is provided at a threaded hole opposite to the third long slot hole. The first connecting component 220 is threadedly connected to the base member 100 by a screw, and the screw is located in the third long slot hole. The screw is loosened to achieve the adjustability of the first connecting component 220 and the base member 100. When the screw is tightened, the first connecting component 220 and the base member 100 are relatively fixed. In another example, the third long slot hole may also be provided on the first connecting component 220, and the base member 100 is provided at a threaded hole opposite to the third long slot hole. The adjustable connection of the first connecting component 220 and the base member 100 along the third direction Z is achieved by the threaded cooperation between the screw and the threaded hole. In other examples, the threaded hole may be replaced with a light hole, and the screw may be replaced with a combination of a bolt and a nut.

[0103] The connection between the first connection component 220 and the first limiting mechanism 310 and the connection between the first limiting mechanism 310 and the base member 100 can be screwed. A fourth long slot hole is provided on the side of the base member 100 facing the first limiting mechanism 310, and a fifth long slot hole is provided on the side of the second connection component 312 facing the first base member 100. The first limiting mechanism 310 is provided with a connecting hole, and one first limiting mechanism 310 is connected to the base member 100 by a first screw, specifically, the first screw passes through the fourth long slot hole and is threadedly connected to the connecting hole. Another first limiting mechanism 310 is connected to the second connecting component 312 by a second screw, specifically, the second screw passes through the fifth long slot hole and is threadedly connected to the connecting hole, so as to realize the relative position of one first limiting mechanism 310 relative to the base member 100 along the second direction Y and the relative position of another first limiting mechanism 310 relative to the second connecting component 312 along the second direction Y can be adjusted.

[0104] Therefore, when the first connecting component 220 is in an unlocked state, the first connecting component 220 is adjusted to move relative to the base component 100, so that the two first limiting mechanisms 310 move toward each other or away from each other along the third direction Z, so as to realize the positions of the two first limiting mechanisms 310 along the third direction Z, so as to clamp objects of different sizes along the third direction Z, and the positions of the two first limiting mechanisms 310 relative to the first clamping component 200 along the second direction Y are adjustable, so that the limiting device 1000 can clamp objects of different sizes along the second direction Y, so as to improve the compatibility of the limiting device 1000.

[0105] In some embodiments, please refer to Figure 1-Figure 3 The first connection assembly 220 includes a first connection member 221 and a first locking mechanism 222. The first connection member 221 is connected to the first one of the first abutting member 211 and the second abutting member 212, and is slidably connected to the base member 100 along the third direction Z. The first locking mechanism 222 is disposed on the first connection member 221. A plurality of first clamping grooves 121 are disposed on a side of the base member 100 facing the first limiting mechanism 310. The plurality of first clamping grooves 121 are arranged along the third direction Z. The first locking mechanism 222 has a first clamping portion 22221. The first clamping portion 22221 can move relative to the first connection member 221 along the first direction X, and at least a portion of the first clamping portion 22221 can move into or out of the first clamping groove 121 along the first direction X.

[0106] Exemplarily, the base member 100 includes a base body 110 and a first rack 120, the base body 110 is connected to the first rack 120 on one side facing the first limiting mechanism 310, the length direction of the first rack 120 is the same as the third direction Z, the back of the teeth on the first rack 120 is arranged against the base body 110, and two adjacent teeth of the first rack 120 form a first clamping groove 121. The base body 110 and the first rack 120 can be connected by welding, screw connection or integral molding. The first clamping portion 22221 is a rack structure, the first clamping portion 22221 moves toward the rack along the first direction X, and can engage with the first rack 120 to achieve the clamping of the first clamping portion 22221 with the first clamping groove 121.

[0107] Exemplarily, the base member 100 also includes a first guide rail assembly 400, which includes a first guide rail 410 and a first slider 420. The first guide rail 410 is connected to the base body 110, specifically by screws. The length direction of the first guide rail 410 is the same as the third direction Z. The first slider 420 is slidably connected to the first guide rail 410 along the third direction Z. The first connecting member 221 is connected to the first slider 420, specifically by screws.

[0108] The first clamping portion 22221 moves away from the first clamping groove 121 along the first direction X, and the locked state can be released, so that the first connecting member 221 can slide relative to the base member 100, and the distance between the two first limiting mechanisms 310 can be adjusted so that the two first limiting mechanisms 310 can clamp battery cells of different sizes along the third direction Z. Then, the first clamping member 2222 moves toward the first clamping groove 121 along the first direction X, so that the first clamping member 2222 is clamped with the first clamping groove 121, so as to facilitate the fixation of the first limiting mechanism 310, thereby enabling the two first limiting mechanisms 310 to clamp the battery cell.

[0109] In some embodiments, please refer to Figure 1-Figure 3 The first locking mechanism 222 includes a first clamping connector 2221 and a first clamping connector 2222. The first clamping connector 2221 is slidably connected to the first connector 221 along the first direction X. The first clamping connector 2222 is located between the first connector 221 and the base member 100 and is connected to the first clamping connector 2221. The end of the first clamping connector 2222 facing the base member 100 forms a first clamping portion 22221.

[0110] Specifically, the first clamping connector 2221 includes a first rod 22211, the first connector 221 is provided with a first connecting hole, the direction of the axis of the first connecting hole is the same as the first direction X, the first rod 22211 is arranged in the first connecting hole, and can slide relative to the first connecting hole, and the first rod 22211 is connected to the end of the base member 100 with the first clamping member 2222. The first connecting hole can be a round hole or a special-shaped hole, and the first connecting hole is a special-shaped hole, which can be limited with the first rod 22211 to limit the circumferential rotation of the first rod 22211, so that the first limited rod can move along its own axial direction, so that the first clamping part 22221 and the first clamping groove 121 are more easily clamped. For example, the first connecting hole is a square hole, and the first rod 22211 is a square rod. The two are plugged together so that the square rod can only move along its own axial direction. The connection between the first rod 22211 and the first clamping connector 2221 can be welding or screw connection. Further optionally, the first snap-fit ​​connector 2221 further includes a first handle 22212 , and the other end of the first rod portion 22211 away from the base component 100 is connected to the first handle 22212 , which may be specifically connected by screws or welding.

[0111] Therefore, by moving the first snap-fit ​​connector 2221, the first snap-fit ​​connector 2222 can be snapped into or out of the first snap-fit ​​groove 121 to achieve locking and unlocking of the first connector 221 and the base component 100, thereby achieving adjustment and fixation of the first limiting mechanism 310 relative to the base component 100 along the third direction Z.

[0112] In some embodiments, please refer to Figure 1-Figure 3 The first locking mechanism 222 also includes a first elastic member 2223, one end of the first elastic member 2223 abuts against the first clamping member 2222, and the other end of the first elastic member 2223 abuts against the first connecting member 221, and the elastic force of the first elastic member 2223 has a tendency to move the first clamping member 2222 toward the first clamping groove 121.

[0113] For example, the first elastic member 2223 can be a compression spring, which is sleeved on the first clamping connector 2221 and is in a compressed state. The compression spring can be replaced by an elastic disc or a rubber spring. In other examples, the first elastic member 2223 can also be a spring.

[0114] Therefore, under the elastic force of the first elastic member 2223 , the squeezing force between the first clamping member 2222 and the first clamping groove 121 can be increased, thereby improving the reliability of the locking connection between the first connecting member 221 and the base component 100 .

[0115] In some embodiments, please refer to Figure 1 and Figure 2The first limiting mechanism 310 also includes a second connecting component 312, which is located on the side of the second abutting component 311 facing the base member 100 and is connected to the second abutting component 311. One of the second connecting components 312 in the two first limiting mechanisms 310 is connected to the base member 100, and the other second connecting component 312 is located on the side of the first connecting component 220 away from the base member 100, and is connected to the first connecting component 220. The second connecting component 312 has a locked state relatively fixed with the first clamping component 200, and an unlocked state moving along the second direction Y relative to the first clamping component 200.

[0116] Optionally, a long slot hole can be set on the surface of the second connecting component 312 facing the base member 100, and the length direction of the long slot hole is the same as the second direction Y. One second connecting component 312 is connected to the base member 100 through a first bolt, and the first bolt is passed through the long slot hole. Another second connecting component 312 is connected to the first connecting component 220 through a second bolt, and the bolt is passed through the long slot hole.

[0117] The connection between the second abutting component 311 and the second connecting component includes, but is not limited to, welding, riveting, bolt connection or integral molding.

[0118] Thus, by unlocking and locking the second connecting component 312, the relative position of the second abutting component 311 and the first abutting component 210 along the second direction Y can be adjusted and fixed, so that the second abutting components 311 of the two first limiting mechanisms 310 abut against the same side of the battery cell.

[0119] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The base member 100 and the first connecting assembly 220 are respectively provided with a plurality of second clamping grooves 710 on one side facing the first limiting mechanism 310, and the plurality of second clamping grooves 710 are arranged along the second direction Y. The second connecting assembly 312 includes a second connecting member 3121 and a second locking mechanism 3122. The second connecting member 3121 is located on the side of the abutting assembly facing the base member 100 and is connected to the abutting assembly. The second connecting member 3121 in one second connecting assembly 312 is slidably connected to the base member 100 along the second direction Y. The second connecting member 3121 in another second connecting assembly 312 is located on the side of the first connecting assembly 220 away from the base member 100 and is slidably connected to the first connecting assembly 220 along the second direction Y. The second locking mechanism 3122 is disposed on the second connecting member 3121 and has a second clamping portion 312221 that can move relative to the first member along the first direction X. At least a portion of the second clamping portion 312221 can move along the first direction X into or out of the second clamping slot 710 .

[0120] Exemplarily, the second connecting member 3121 of one first connecting assembly 220 can be slidably connected to the base member 100 along the second direction Y through the second guide rail assembly 500, and the second connecting member 3121 of another first connecting assembly 220 is slidably connected to the first connecting assembly 220 through the third guide rail assembly 600. Specifically, optionally, the second guide rail assembly 500 includes a second guide rail 510 and a second slider 520, the base member 100 is provided with a second guide rail 510 in a direction toward the first limiting mechanism 310, the length direction of the second guide rail 510 is the same as the second direction Y, a slider is slidably connected to the second guide rail 510, and one first connecting assembly 220 is connected to the second slider 520, which can be specifically connected by screws. The third guide rail assembly 600 includes a third guide rail 610 and a third slider 620. The third guide rail 610 is connected to the side of the first connecting member 221 of the first connecting member 221 assembly facing away from the base member 100. The length direction of the third guide rail 610 is the same as the second direction Y. The third guide rail 610 is slidably connected to the third slider 620. The second connecting member 3121 of another first connecting assembly 220 is connected to the third slider 620.

[0121] Optionally, a tooth structure is formed between two adjacent second clamping grooves 710. The second clamping portion 312221 forms a second clamping protrusion, and the number of the second clamping protrusions can be one or more. Exemplarily, the number of the second clamping protrusions is multiple, and the multiple second clamping protrusions are arranged along the second direction Y.

[0122] For example, please refer to Figure 2, one second limiting assembly is connected to the base member 100 through the second connecting assembly 312, and the other second limiting assembly is connected to the first connecting assembly 220 through the second connecting assembly 312. Specifically, optionally, a second rack 700 is provided on one side of the base member 100 facing the second limiting assembly and on one side of the first connecting assembly 220 facing the second limiting assembly. The length direction of the second rack 700 is the same as the second direction Y, the teeth on the second rack 700 are arranged opposite to the second clamping protrusion, and two adjacent teeth of the second rack 700 form a second clamping groove 710. The second clamping portion 312221 is a rack structure, and the second clamping portion 312221 moves toward the second rack 700 along the first direction X, and can engage with the second rack 700 to achieve the clamping of the second clamping portion 312221 with the second clamping groove 710.

[0123] Thus, by unlocking and locking the second locking mechanism 3122, it is possible to realize the movement and fixation of a first limiting mechanism 310 relative to the base member 100 along the second direction Y, and the movement and fixation of another first limiting mechanism 310 relative to the first connecting component 220 along the second direction Y, thereby realizing the movement of the second abutment component 311 of the two second limiting components and the first abutment component 210 along the second direction Y, so that battery cells of different sizes can be clamped along the second direction Y; at the same time, adjusting the first connecting component 220 so that the first connecting component 220 moves relative to the base member 100 along the third direction Z, the relative position of the second abutment components in the two second limiting components can be changed, so that battery cells of different sizes can be clamped along the third direction Z, thereby improving the compatibility of the limiting device 1000.

[0124] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The second locking mechanism 3122 includes a second clamping connector 31221 and a second clamping connector 31222. The second clamping connector 31221 is slidably connected to the second connector 3121 along the first direction X. The second clamping connector 31222 is located on a side of the second clamping connector 31221 facing the base member 100 and is connected to the second clamping connector 31221. The end of the second clamping connector 31222 facing the base member 100 forms a second clamping portion 312221.

[0125] Specifically, the second clamping connector 31221 includes a second rod portion 312211, the second connector 3121 is provided with a second connecting hole, the direction of the axis of the second connecting hole is the same as the first direction X, the second rod portion 312211 is inserted into the second connecting hole, and can slide relative to the second connecting hole, and the end of the second rod portion 312211 facing the base member 100 is connected with a second clamping member 31222. The second connecting hole can be a round hole or a special-shaped hole, and the second connecting hole is a special-shaped hole, which can be limited with the second rod portion 312211 to limit the circumferential rotation of the second rod portion 312211, so that the second limiting rod portion can move along its own axial direction, so that the second clamping portion 312221 is easier to clamp with the second clamping groove 710. For example, the second connecting hole is a square hole, and the second rod portion 312211 is a square rod, and the two are plugged together so that the square rod can only move along its own axial direction. The connection between the second rod 312211 and the second clamping connector 31221 can be welding or screw connection, etc. Further optionally, the second clamping connector 31221 also includes a second handle 312212, and the other end of the rod away from the first one is connected to the second one, which can be screwed or welded.

[0126] Therefore, by moving the second snap-fit ​​connector 31221, the second snap-fit ​​connector 31222 can be snapped into or disengaged from the second snap-fit ​​groove 710 to achieve locking and unlocking of the second connector 3121 with the above-mentioned first one, thereby achieving adjustment of the relative position of the second abutment component 311 in the two second limiting components along the second direction Y with the first abutment component 210, and locking and fixing of the second abutment component 311.

[0127] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The second locking mechanism 3122 also includes a second elastic member 31223, one end of the second elastic member 31223 abuts against the second clamping member 31222, and the other end of the second elastic member 31223 abuts against the second connecting member 3121, and the elastic force of the second elastic member 31223 has a tendency to move the second clamping member 31222 toward the second clamping groove 710.

[0128] For example, the second elastic member 31223 can be a compression spring, which is sleeved on the second clamping connector 31221 and is in a compressed state. The compression spring can be replaced by an elastic disc or a rubber spring. In other examples, the second elastic member 31223 can also be a spring.

[0129] Therefore, under the elastic force of the second elastic member 31223 , the squeezing force between the second clamping member 31222 and the second clamping groove 710 can be increased, thereby improving the reliability of the locking.

[0130] In some embodiments, a weight-reducing groove 111 is provided on one side of the base member 100 facing the first limiting mechanism 310, and the number of the weight-reducing grooves 111 may be multiple, and the multiple weight-reducing grooves 111 are arranged at intervals along the second direction Y. The weight-reducing grooves 111 can reduce the weight of the base member 100, making the limiting device 1000 lighter as a whole.
