TECHNICAL FIELD

[0001] The utility model relates to the technical field of battery cell module, specifically relates to a module connecting support auxiliary tool. BACKGROUND

[0002] With the promotion of environmental awareness and policy, the new energy vehicle market develops rapidly in the global scope, and the demand of new energy battery also grows rapidly. The battery packaging assembly is a complex and key process, which directly affects the performance and safety of the battery pack, and the module size is the key control object in the assembly process, and the material after assembly in production and manufacturing does not meet the size, which can cause rework, scrap material and other problems. Therefore, the size position degree needs to be limited in the assembly of the module, and due to the limited space in the box, the module position degree problem cannot be completely limited.

[0003] In the prior art, the module is formed by pulling each small module through the module pull rod, and the PTC between each small module needs to be connected and fixed with the connecting support through the bolt, but when the connecting support is installed, the support will rotate with the stress surface, so that the hole position on the connecting support and the hole position on the PTC are out of position and the bolt cannot be installed. And each small module on the side of the module is not in the same plane, which can also cause the hole position of the module side plate and the hole position of the module box to be out of position, so that the auxiliary installation is needed when the module is assembled, especially the installation of the connecting support of the module before the module is put into the box to ensure the position degree.

[0029] according to Figures 1-2As shown, this embodiment provides an auxiliary tooling for a module connection bracket, including a main beam 10. The length of the main beam 10 is designed according to the module width. In this embodiment, the length of the main beam 10 is 680mm. Three receiving slots 20 are provided on the surface of the main beam 10, with a spacing of 290mm between them. This allows for the simultaneous connection of three PTC1 units inside the module to the connection bracket 2 via bolts. Figure 2 As shown.

[0030] The receiving groove 20 includes an outer side plate 21, an inner side plate 22, and a groove bottom 23. The bottoms of the outer side plate 21 and the inner side plate 22 are connected to the groove bottom 23 to form the receiving groove 20. The outer side plate 21 is connected to one side of the main beam 10, and the inner side plate 22 is connected to the other side of the main beam 10. The groove bottom 23 is located in the middle of the inner and outer side plates, and the width of the groove bottom 23 matches the connecting bracket 2, enabling the connecting bracket 2 to be fixed inside the receiving groove 20. The top corners of the outer side plate 21 and the inner side plate 22 are rounded to prevent damage to the module and to facilitate installation and use.

[0031] The groove bottom 23 is provided with two limiting pins 231. The limiting pins 231 are fixed in the middle position of the groove bottom 23, which can place the hole of the connecting bracket 2 in the limiting pins 231, and can limit the connecting bracket 2 from moving and rotating when tightening the bolts.

[0032] The inner side plate 22 has a first groove 221 on its top, which is located in the middle of the inner side plate 22 and has a chamfered interior. The first groove 221 is used to fix the PTC1 of the module. The PTC1 has two holes. The connecting bracket 2 is fixed to both sides of the PTC1 and then connected to the PTC1 by two bolts.

[0033] The bottom of the inner test plate 22 is provided with a second groove 222, which is reserved for the position of the ranging device. The second groove 222 is located below the first groove 221. The ranging device is fixedly installed in the second groove 222. The ranging device is a laser ranging device. The laser ranging device can measure the distance from the end face of each small module to the main beam 10. By adjusting the position of the main beam 10 or the position of each small module, the small modules and the main beam 10 can be made to be on the same plane or within the error range. This can solve the problems of module insertion difficulty and hole offset caused by uneven end faces of each small module.

[0034] The main beam 10 is provided with limiting blocks 11 at both ends. The limiting blocks 11 are in contact with the two sides of the module and can limit the basic size of the module. The limiting blocks 11 cooperate with the module tie rod to determine the final size of the module.

[0035] The method for using the module connection bracket auxiliary tooling in this embodiment is as follows:

[0036] First, align each small module and the module connecting bracket auxiliary tooling on the same horizontal plane. Adjust the position between each small module and the tooling to fix the PTC1 of each small module in the first groove 221 of the inner side plate 22. Then, adjust the position between each small module and the main beam 10 according to the laser ranging device, so that each small module and the main beam 10 are on the same plane or within the error range. Use the module tie rod to tighten each small module and assemble it into a module. Finally, place the connecting bracket 2 in the receiving groove 20 so that the hole of the connecting bracket 2 can be placed in the limiting pin 231. The connecting bracket 2 is fixed on both sides of the PTC1. After the connecting bracket 2 is fixed, use bolts to connect the connecting bracket 2 and the PTC1 to complete the connection between the connecting bracket 2 and the module.

[0037] In summary, this embodiment uses a module connecting bracket auxiliary tooling to facilitate the connection between the connecting bracket 2 and the PTC1 in the module, and improves the positioning accuracy and ease of operation through the limiting block 11 and the ranging device.

[0038] In this embodiment, the X-axis rotation of the connecting bracket 2 is restricted by the inner and outer side plates, and the limiting pin 231 facilitates the determination of the position of the connecting bracket 2 when it is installed. The PTC1 between each small module is fixed by the first groove 221, which facilitates the installation of the connecting bracket 2 onto the PCT1. By setting a distance measuring device to measure the distance between the end faces of multiple small modules and the side of the main beam of the connecting bracket, it can be ensured that the sides of multiple small modules are on the same plane or within the error range.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
