DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model and cannot be understood as limiting the utility model.

[0025] The embodiments of the utility model will be described below according to the overall structure of the utility model.

[0026] The application provides a kind of line connection auxiliary mechanism for insulating battery module processing, for forming module between single battery parallel, specifically, according to the distance between different battery positive and negative pole size adjustment, it is convenient to connect, and it is protected after battery connection, increase the security performance of battery module connection.

[0027] As Figure 3 , Figure 3The schematic diagram of the adjusting mechanism 2 of the application is shown, which comprises an adjusting groove 201, an adjusting rod 202 and an adjusting sleeve 203. The positive and negative electrode connecting sheets 1 are threadedly connected with the adjusting sleeve 203 through the adjusting rod 202. When connecting the battery modules 5, the positive and negative electrode connecting sheets 1 are used for power supply. However, due to the different shapes and sizes of different battery modules 5, the positive and negative electrode connecting sheets 1 need to be adjusted in size to meet the connection between battery modules 5 of different sizes. First, the positive and negative electrode connecting sheets 1 are sleeved on the outer wall of the positive and negative electrode connecting blocks 6 above the battery modules 5. Then, according to the distance between the positive and negative electrode connecting blocks 6 of the two battery modules 5, the adjusting sleeve 203 is rotated to release the locking state of the adjusting rod 202 and the positive and negative electrode connecting sheets 1. Then, the positive and negative electrode connecting sheets 1 are pulled to adjust to the appropriate position. Then, the adjusting sleeve 203 is reversely rotated to press and fix the adjusting rod 202 and the positive and negative electrode connecting sheets 1. Then, the pulled positive and negative electrode connecting sheets 1 are sleeved on the outer wall of the positive and negative electrode connecting blocks 6, so that the battery modules 5 are completed for power supply, and the adaptability of the connection of the positive and negative electrode connecting sheets 1 is increased.

[0028] As Figure 4 , Figure 4 The schematic diagram of the limiting mechanism 3 of the application is shown, which comprises a limiting rod 301, a limiting plate 302 and a limiting spring 303. The limiting rod 301 is movably connected with the positive and negative electrode connecting sheets 1. The limiting plate 302 and the positive and negative electrode connecting sheets 1 constitute a telescopic structure through the limiting spring 303. When the positive and negative electrode connecting sheets 1 are fixed with the positive and negative electrode connecting blocks 6, due to the different diameters of the positive and negative electrode connecting blocks 6 above different battery modules 5, the positive and negative electrode connecting sheets 1 cannot be connected with the positive and negative electrode connecting blocks 6 during connection. Through the elastic property of the limiting spring 303, the limiting plate 302 is pushed inward to tightly fit with the positive and negative electrode connecting blocks 6. The limiting plate 302 is used in cooperation with the limiting rod 301 and the limiting spring 303 to enable the positive and negative electrode connecting sheets 1 to be clamped and connected with positive and negative electrode connecting blocks 6 of different sizes, thereby increasing the applicability of the device.

[0029] As Figure 5 , Figure 5 The schematic diagram of the protection mechanism 4 of the application is shown, which comprises a positioning rod 401, a positioning sleeve 402, a sliding groove 403, a fixed shaft 404 and a cover plate 405. The positioning rod 401 is slidably connected with the sliding groove 403. The positioning sleeve 402 is clamped with the cover plate 405. After the connection of the battery modules 5 is completed, the connection between the positive and negative electrode connecting sheets 1 and the positive and negative electrode connecting blocks 6 is prone to loosening due to collision. When foreign matters hit the top of the battery modules 5, the battery modules 5 are prone to damage. The cover plate 405 is slidably connected with the positioning sleeve 402 to shield and protect the battery modules 5 above to avoid damage to the battery modules 5 or loosening of the connection between the positive and negative electrode connecting sheets 1 and the positive and negative electrode connecting blocks 6 due to the impact of foreign matters.

[0030] Working principle: in use, first move the device to the desired position, then according to the size of the positive and negative connection block 6, by rotating the adjusting sleeve 203 and adjusting rod 202 threaded adjustment, the distance between the positive and negative connection piece 1 can be adjusted, then the positive and negative connection piece 1 is respectively fixed on the positive and negative connection block 6 above, so that the battery module 5 is powered on, the setting of the adjusting rod 202 and the adjusting sleeve 203 increases the adaptability of the device, then because the diameter of the positive and negative connection block 6 of different models of battery module 5 is different, and the size of the connecting groove in the traditional positive and negative connection piece 1 is fixed design, which may cause the positive and negative connection piece 1 cannot be sleeved on the positive and negative connection block 6, and the limiting plate 302 can be sleeved and fixed on the positive and negative connection block 6 according to the different size of the positive and negative connection block 6 through the elastic force of the limiting spring 303, which increases the applicability of the device, finally the positioning sleeve 402 is fixed on the battery module 5 above through the fixed shaft 404, then when the positive and negative connection piece 1 and the positive and negative connection block 6 above the battery module 5 are installed, the cover plate 405 is clamped and fixed with the positioning sleeve 402, the line connection of the lower positive and negative connection piece 1 is shielded and protected, the safety of the device is increased, so the use process of the device is completed, the contents not described in detail in the specification belong to the prior art known to those skilled in the art.
