DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , Figure 3 and Figure 4 , a separator bracket for battery electrode group laminations:

[0025] Including: a mounting plate 1, a fixing frame 2 is fixedly connected to the top of the mounting plate 1, rubber strips 3 are fixedly connected to the four sides of the top of the fixing frame 2, T-shaped grooves are formed on the front and rear sides of the fixing frame 2, sliding blocks 4 are slidably connected to the front and rear sides of the inner bottom wall of the mounting plate 1, a telescopic tube 5 is slidably connected to the inner wall of the front surface of the sliding block 4, and the front end of the telescopic tube 5 is fixedly connected to the inner wall of the mounting plate 1. A spring 6 is connected to the inner wall of the telescopic tube 5. A T-shaped slider 7 is fixedly connected to the bottom of the sliding block 4, and the horizontal cross-section of the T-shaped slider 7 is the same as that of the T-shaped groove. A push-pull rod 8 is fixedly connected to the front surface of the T-shaped slider 7. The top of the rubber strip 3 abuts against a top plate 9, and the surfaces of the sliding blocks 4 are slidably connected to the front and rear sides of the inner bottom wall of the top plate 9.

[0026] When using this device to perform the combined installation work on battery laminations, place the battery laminations in the fixing frame 2 so that the battery laminations are on top of the mounting plate 1. Then pinch the push-pull rod 8 and pull it outwards, causing the push-pull rod 8 to drive the T-shaped slider 7 to move forward. The T-shaped slider 7 drives the sliding block 4 at the top to slide on the inner wall of the mounting plate 1. The sliding block 4 drives the telescopic tube 5 to contract into the inner wall of the sliding block 4, and the telescopic tube 5 squeezes the spring 6. Then place the mounting plate 1 on top of the second group of fixing frames 2. At this time, the second group of fixing frames 2 and the first group of mounting plates 1 are sealed by the rubber strips 3, causing the rubber strips 3 to be squeezed to reduce the gap between them. Then release the T-shaped slider 7, causing the spring 6 to rebound and push the sliding block 4, so that the sliding block 4 drives the T-shaped slider 7 to slide into the groove of the fixing frame 2, thus completing the combined installation of two groups of battery laminations. Multiple sets of devices are combined to complete the combined installation of multiple groups of battery laminations.

[0027] Please refer to Figure 1 and Figure 2 On the front and rear sides of the fixing frame 2, connection rods 10 are fixedly connected. The front ends of the connection rods 10 are fixedly connected to a connection box 11. A plug-in block 12 is fixedly connected to the top of the connection box 11, and the size of the plug-in block 12 is the same as that of the groove at the bottom of the connection box 11.

[0028] When using this device to position and fix the mounting plate 1 and the fixing frame 2, place the second group of mounting plates 1 on top of the first group of mounting plates 1, and insert the first group of plug-in blocks 12 into the connection box 11, so that the two groups of mounting plates 1 are on the same horizontal line, thus completing the positioning of the mounting plate 1 and facilitating the combined installation of battery laminations.

[0029] Please refer to Figure 2 and Figure 5, fixed plates 13 are lapped on both the front and rear sides of the bottom of the mounting plate 1. A telescopic plate 14 is slidably connected to the inner walls of the two groups of fixed plates 13. A connecting box 15 is fixedly connected to the bottom of the fixed plate 13. Connecting plates 16 are fixedly connected to both the left and right sides of the bottom of the telescopic plate 14. A connecting rod 17 is fixedly connected to the bottom of the connecting plate 16. A screw rod 18 is threadedly connected to the front end of the connecting rod 17. A limiting plate 19 is fixedly connected to the front end of the screw rod 18. A knob 20 is fixedly connected to the front surface of the limiting plate 19.

[0030] When using this device to fix the mounting plate 1, stick the connecting box 15 at the designated position. Then rotate the knob 20, causing the knob 20 to drive the limiting plate 19 to rotate. The limiting plate 19 drives the screw rod 18 at its tail to rotate, causing the limiting plate 19 to become disengaged from the connecting box 15. Then pull the telescopic plate 14 to both the left and right sides until the telescopic plate 14 reaches both sides of the mounting plate 1. Then bring the mounting plate 1 into contact with the telescopic plate 14, and push the telescopic plate 14 towards the middle, causing the fixed plate 13 to clamp the mounting plate 1. Then rotate the knob 20, causing the knob 20 to drive the limiting plate 19 to rotate and move into contact with the connecting box 15, thereby fixing the telescopic plate 14 and then completing the connection and fixation between the telescopic plate 14 and the mounting plate 1.

[0031] Working principle: Place the battery stack in the fixing rack 2. Then pull the T-shaped slider 7 at the bottom of the second group of mounting plates 1 outwards and lap it on the top of the first group of fixing racks 2. At this time, the rubber strip 3 reduces the gap between the two, and causes the plug-in block 12 to be inserted into the connection box 11, thereby completing the positioning of the two groups of mounting plates 1. Then release the T-shaped slider 7, causing the spring 6 to push the T-shaped slider 7, causing the T-shaped slider 7 to be inserted into the groove of the fixing rack 2, and then completing the connection and fixation between the two groups of mounting plates 1 and the fixing rack 2. Then install multiple groups of mounting plates 1 according to the same operation, so as to complete the combined installation of multiple groups of battery stacks. Then stick the bottom of the connecting box 15 at the designated position, pull the fixed plate 13 outwards, then place the mounting plate 1 on top of the fixed plate 13, and push the fixed plate 13, causing the fixed plate 13 to clamp the fixing rack 2. Then rotate the knob 20, causing the knob 20 to drive the limiting plate 19 to contact the connecting box 15. At this time, the friction between the connecting box 15 and the limiting plate 19 is relatively large and it is difficult to move, thereby completing the installation and fixation of the battery stack.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive.
