[0030] In one embodiment of the present invention, referring to Figure 1 and Figure 2, an auxiliary clamping mechanism for a large flat soft-pack battery, comprising a first clamping plate 100, a second clamping plate 200, and a locking mechanism 300; the locking mechanism 300 is used to lock the first clamping plate 100 and the second clamping plate 200. The first clamping plate 100 and the second clamping plate 200 are clamped together to form a receiving cavity for receiving a battery cell, and when the battery is clamped, the battery is positioned in the receiving cavity. The upper end of the receiving cavity is provided with a clearance position for avoiding an air outlet of the battery, and both sides and the lower end of the clamping surface of the first clamping plate 100 are provided with a pressing member 400. Specifically, the battery cell part of the large flat battery is placed in the accommodating cavity formed by the first clamping plate 100 and the second clamping plate 200, and the unsealed end of the battery passes through the avoidance position, and the locking mechanism 300 locks the first clamping plate 100 and the second clamping plate 200, so that the clamping member 400 presses the sealed edge of the battery on the inner side of the second clamping plate 200, thereby tightening the battery, thereby fixing and positioning the battery and preventing it from deforming. Therefore, during the battery processing and production, deformation can be prevented, and normal production and transportation during the production process can be guaranteed.

[0031] Furthermore, the pressing member 400 is an elastic pressing member. In this embodiment, since the pressing member 400 is an elastic member, when pressing the edge of the battery, the pressing member 400 is compressed, while the first clamping plate 100 and the second clamping plate 200 can still move toward each other, thereby achieving the effect of fixing the battery, and avoiding interference between the first clamping plate 100 and the second clamping plate 200 and the pressing member 400 when clamping the battery.

[0032] Further, refer to Figure 6 and Figure 7 , the number of the pressing members 400 arranged on both sides and the lower end of the clamping surface of the first clamping plate 100 is multiple. The pressing member 400 includes a pressing block 401 and a compression spring 402. The first clamping plate 100 is provided with a step hole for installing the pressing block 401, and the two sides of the pressing block 401 are provided with limiting parts 403, one end of the pressing block 401 passes through the step hole, and the two limiting parts 403 are limited on the step surface of the step hole; the compression spring 402 is arranged in the step hole, one end of the compression spring 402 abuts against the top wall of the step hole, and the other end abuts against the end of the pressing block 401. In this embodiment, when the first clamping plate 100 and the second clamping plate 200 press the battery, when the pressing block 401 contacts the second clamping plate 200, the compression spring 402 is compressed to press the edge of the battery, and at the same time, the first clamping plate 100 and the second clamping plate 200 move toward each other to further fix the battery cell.

[0033] Further, refer to Figure 2 and Figure 6The first clamping plate 100 includes a frame 110, a cover plate 120 and a silicone plate 130. The outer side of the frame 110 is provided with an inwardly recessed mounting position, the cover plate 120 is installed in the mounting position, and the silicone plate 130 is arranged on the inner side of the cover plate 120; the upper end of the inner side of the frame 110 is provided with a notch 111 forming the avoidance position. In this embodiment, when positioning the battery, the cover plate 120 and the silicone plate 130 cooperate with the second clamping plate 200 to press tightly, so as to protect the battery, and the frame 110 plays a role in positioning the battery. In addition, the cover plate 120 can also limit the end of the compression spring 402.

[0034] Further, refer to Figure 3 , Figure 4 and Figure 5The locking mechanism 300 is provided in multiple groups and is arranged on the first clamping plate 100; the locking mechanism 300 includes a connecting sleeve 310, a locking spring 320, a movable pin 330, a limiting pin 340 and a pressing sleeve 350. The inner side of the first clamping plate 100 is provided with a mounting hole 101, the bottom of the mounting hole 101 is provided with a through hole to avoid air, the connecting sleeve 310 is installed in the mounting hole 101, a blind hole is provided in the connecting sleeve 310, the bottom of the blind hole is provided with a sliding hole, the movable pin 330 slides through the sliding hole, specifically, the movable pin 330 is clearance-matched with the sliding hole, the locking spring 320 and the pressing sleeve 310 are sequentially sleeved on one end of the movable pin 330 extending into the blind hole, the end of the movable pin 330 is provided with a limiting ring 331 for limiting the pressing sleeve 310, and the end of the movable pin 330 is provided with a slot, which is convenient for connecting with a tool for rotating the movable pin 330. The limit pin 340 passes through the movable pin 330 and extends out of one end of the blind hole. The locking spring 320 pushes the limit pin 340 to be limited at the end of the connecting sleeve 310. The second clamping plate 200 is provided with a connecting hole 201 corresponding to the locking mechanism 300, and both sides of the connecting hole 201 are provided with a clearance groove 202 to avoid the limit pin 340. The pressing sleeve 310 is pushed to compress the locking spring 320, so that the movable pin 330 can slide along the sliding hole, and the limit pin 340 passes through the second clamping plate 200 through the two clearance grooves 202. The movable pin 330 is rotated so that the limit pin 340 is misaligned with the clearance groove 202 and is limited on the outside of the second clamping plate 200. In this embodiment, when the first clamping plate 100 and the second clamping plate 200 are locked, they are locked by the locking mechanism 300; specifically, by pushing the pressing sleeve 350, the locking spring 320 is engaged, so that the locking spring 320 releases the movable pin 330, so that the movable pin 330 can rotate freely; therefore, when the movable pin 330 is rotated, the limiting pin 340 is misaligned with the avoidance groove 202, and the limiting ring 331 of the movable pin 330 and the locking spring 320 will not cause friction, which can not only avoid wear of the two, but also smoothly rotate the movable pin 330. In addition, in this embodiment, the locking spring 320 is used to provide the locking force, so that the clamping force is too large to crush the battery, thereby protecting the battery.

[0035] Further, refer to Figure 2 and Figure 4 The outer side of the second clamping plate 200 is further provided with positioning grooves 203 located on both sides of the connecting hole 201, and the positioning grooves 203 are staggered with the air-avoiding grooves 202. Specifically, the positioning grooves 203 and the air-avoiding grooves 202 are staggered by 90 degrees. In this embodiment, when the limiting pin 340 is limited on the outer side of the second clamping plate 200, the limiting pin 340 is positioned in the positioning groove 203 to prevent the movable pin 330 from rotating.

[0036] Further, refer to Figure 3 and Figure 5 A pressing ring 351 extends outward from the periphery of the pressing sleeve 350, and the limiting ring 331 is located inside the pressing ring 351. In this embodiment, the pressing sleeve 350 can be pushed by squeezing the pressing ring 351, so that the pressing sleeve 350 is easily squeezed.

[0037] Furthermore, the number of the locking mechanisms 300 is four, and they are distributed at the four corners of the first clamping plate 100. In this embodiment, the four locking mechanisms 300 are distributed at the four corners of the first clamping plate 100, so that the clamping force of the first clamping plate 100 and the second clamping plate 200 to clamp the battery is uniform.

[0038] Further, refer to Figure 2 , Figure 6 and Figure 8 The upper end of the second clamping plate 200 is provided with a support plate 204 extending upward, and the support plate 204 is provided with a plurality of air avoidance areas, and the air avoidance areas are hollow structures; the upper end of the first clamping plate 100 is provided with a plurality of support limiters 102, which are used to support and limit the battery exhaust port with the support plate 204. In this embodiment, the support plate 204 and the support limiter 102 play a guiding and supporting role on the battery mouth, which is convenient for liquid injection and exhaust, etc. Further, the height of the support limiter 102 is less than the height of the support plate 204.

[0039] Furthermore, support legs 210 are provided on both sides of the bottom of the first clamping plate 100 and the second clamping plate 200. In this embodiment, the support legs 210 support the combination of the first clamping plate 100 and the second clamping plate 200 to prevent the tabs of the battery from contacting the support surface and causing the tabs to bend, thereby protecting the tabs.

[0040] Further, refer to Figure 8 The inner side of the second clamping plate 200 is provided with a recessed cavity 205, and a fixing frame 206 is provided in the cavity 205 for positioning the battery cell. In this embodiment, when the battery is clamped between the first clamping plate 100 and the second clamping plate 200, the fixing frame 206 plays a role in positioning the battery cell, further avoiding battery deformation and ensuring uniform distribution of the structure inside the battery cell.

[0041] Furthermore, a positioning pin is disposed on the inner side of the second clamping plate 200 , and a positioning hole matched with the positioning pin is disposed on the inner side of the first clamping plate 100 .
