[0030] See also Figures 1 to 4 As shown, an embodiment of the utility model provides an automatic clamp 10 for cylindrical batteries, which includes a clamp base 100 and a clamping assembly 200; the clamping assembly 200 includes a clamping member 210, a pressing block 220 and a reset member 230, the clamping member 210 is provided with a guide groove 211 and a clamping groove 212 for accommodating the cylindrical battery 20, the pressing block 220 is provided with a guide portion 221, the guide groove 211 and the guide portion 221 are slidably matched, and the guide groove 211 and the guide portion 221 are set at an angle to the moving direction of the clamping member 210; the reset member 230 is connected to the pressing block 220, and the number of the clamping members 210 is two; the reset member 230 is used to drive the pressing block 220 to move toward the clamp base 100, so as to drive the two clamping members 210 to move toward the cylindrical battery 20.

[0031] When using the automatic clamp 10 of this embodiment, first drive the pressing block 220 to move away from the clamp base 100 so that the two clamping members 210 move away from each other, and then place the cylindrical battery 20 between the two clamping members 210 and make it correspond to the clamping groove 212. After releasing the pressing block 220, the pressing block 220 can drive the two clamping members 210 to move toward the cylindrical battery 20 and clamp the cylindrical battery 20 through the cooperation of the guide groove 211 and the guide part 221; when the cylindrical battery 20 needs to be released, move the pressing block 220 in the opposite direction.

[0032] In the automatic clamp 10 of this embodiment, by arranging the clamping member 210, the pressing block 220 and the resetting member 230 to cooperate, the cylindrical battery 20 can be quickly clamped and released, the structure is simple, and the clamping efficiency and stability are good.

[0033] Specifically, the clamp base 100 includes a base body 110 and a positioning pin 120, the positioning pin 120 is connected to the base body 110; the clamp 210 is provided with a positioning groove 2131, the positioning pin 120 is inserted into the positioning groove 2131, and the clamp 210 and the base body 110 are relatively movable.

[0034] In this embodiment, the positioning groove 2131 is a strip groove. By providing a positioning pin 120 to cooperate with the positioning groove 2131, not only the movement smoothness of the clamping member 210 can be improved, but also the movement of the clamping member 210 can be limited.

[0035] In one embodiment, the base body 110 is provided with a slide groove 112 , the clamping member 210 is provided with a guide protrusion 213 , and the guide protrusion 213 is slidably matched with the slide groove 112 , and the positioning groove 2131 is provided on the guide protrusion 213 .

[0036] Thus, by arranging the slide groove 112 and the guide protrusion 213 on the base body 110, the linear movement of the clamping member 210 can be further guided, and the movement stability of the clamping member 210 can be improved; in addition, by arranging the positioning groove 2131 on the guide protrusion 213, the combined structure of the clamping member 210 and the base body 110 can be made more compact, and because the guide protrusion 213 can be movably accommodated in the slide groove 112, the positioning pin 120 can be prevented from being damaged by collision, thereby improving the reliability of the automatic clamp 10.

[0037] Furthermore, the clamp base 100 further includes a limiting pin 130 , which is detachably connected to the base body 110 , and the limiting pin 130 is at least partially located between the two clamping members 210 .

[0038] In this embodiment, by setting a limit pin 130 to cooperate with the clamping member 210, the clamping width of the clamping member 210 can be limited. When the clamping member 210 clamps a cylindrical battery 20 of a preset size, in order to avoid the clamping member 210 from clamping the cylindrical battery 20, after the clamping member 210 moves to a preset position, the clamping member 210 can abut against the limit pin 130 to limit the movement of the clamping member 210; of course, the limit pin 130 and the base body 110 can be combined in a detachable connection manner such as a threaded connection or a plug-in connection, which can facilitate the disassembly and replacement of the limit pin 130.

[0039] In one embodiment, the clamping assembly 200 further includes an adjusting member 240 , which is connected to the pressing block 220 and to the resetting member 230 . The resetting member 230 is used to drive the adjusting member 240 to move so as to drive the pressing block 220 to move.

[0040] When using the automatic clamp 10 of this embodiment, the operator can pull the adjusting member 240 to drive the pressing block 220 to move, so as to drive the two clamping members 210 to move in a direction away from each other, so that there is a space between the two guide grooves 211 for inserting the cylindrical battery 20. In a preferred embodiment, the guide groove 211 is a T-shaped groove, and the cross-section of the guide portion 221 is a T-shaped structure, thereby effectively improving the guiding accuracy of the clamping member 210 and the pressing block 220. In the process of the pressing block 220 moving toward or away from the base body 110, the two can cooperate with the guide groove 211 and the guide portion 221 to achieve synchronous movement of the clamping member 210 and the pressing block 220; when the cylindrical battery 20 is inserted between the two guide grooves 211, the two clamping members 210 can be clamped on both sides of the cylindrical battery 20 driven by the elastic force of the reset member 230 by releasing the adjusting member 240 to achieve the automatic clamping function.

[0041] Specifically, the reset member 230 includes a reset spring 231 and a reset connector 232, the reset connector 232 is connected to the end of the adjusting member 240, the reset spring 231 is respectively connected to the reset connector 232 and the clamp base 100, and the reset spring 231 is used to drive the pressure block 220 to drive the clamp 210 to clamp the cylindrical battery 20.

[0042] In this embodiment, by setting the return spring 231 and the pressure block 220 and the clamp base 100, when the two clamping members 210 are opened, the return spring 231 can undergo elastic deformation and store elastic potential energy, thereby driving the two clamping members 210 to move toward each other through the elastic force to achieve the function of automatically clamping and fixing the cylindrical battery 20.

[0043] Furthermore, the clamp base 100 is provided with a receiving cavity 111 , which is provided at a side of the clamp base 100 away from the clamping member 210 , and the return spring 231 is movably received in the receiving cavity 111 .

[0044] By setting up a receiving cavity 111 in the clamp base 100 for receiving the reset spring 231, the combined structure of the reset member 230 and the clamp base 100 can be made compact, and the reset spring 231 can also be protected and limited to prevent the reset spring 231 from exceeding the space of the receiving cavity 111 when deformed.

[0045] Specifically, the pressing block 220 is provided with an installation cavity 222, and the adjusting member 240 includes a pulling portion 241 and a connecting portion 242 connected to each other. The connecting portion 242 is penetrated into the installation cavity 222 and connected to the reset connecting member 232. The reset spring 231 is sleeved on the connecting portion 242. The pulling portion 241 is arranged on the side of the pressing block 220 away from the clamp base 100. The pressing block 220 is provided with a fixing hole 223 connected to the installation cavity 222. The clamping assembly 200 also includes a fixing pin 250, which is penetrated through the fixing hole 223 and fixedly connected to the connecting portion 242.

[0046] When assembling the automatic clamp 10 of this embodiment, first insert the connecting part 242 into the installation cavity 222 of the pressure block 220, then pass the fixing pin 250 through the fixing hole 223 into the pressure block 220 and connect it to the connecting part 242 at the same time, thereby the adjusting member 240 and the pressure block 220 can be connected and fixed, and then the reset spring 231 is sleeved on the connecting part 242 so that the end of the reset spring 231 abuts against the end inner wall of the accommodating cavity 111, and then the reset connecting member 232 is connected to the end of the connecting part 242 away from the pulling part 241, and the reset connecting member 232 abuts against the other end of the reset spring 231, thereby the reset member 230 can be combined with the adjusting member 240 and the clamp base 100, which has a simple structure and is easy to assemble.

[0047] Furthermore, the clamping member 210 is also provided with anti-skid patterns 2121 , which are arranged in the clamping groove 212 and are used to contact the cylindrical battery 20 .

[0048] In this embodiment, by providing an anti-skid pattern 2121 on the inner side of the clamping groove 212 to cooperate with the cylindrical battery 20, the friction between the clamping member 210 and the cylindrical battery 20 can be increased, thereby further improving the clamping stability of the clamping member 210. Specifically, the anti-skid pattern 2121 can be an anti-skid knurling, an anti-skid groove, or an anti-skid layer, which is not limited here.
