Technical Field
[0001] The utility model relates to the technical field of PACK, in particular to a nickel sheet structure for 32 cylindrical batteries. Background Art
[0002] With the increasing shortage of energy and the continuous progress of technology, electric vehicles have developed rapidly. One of the key technologies for the development of electric vehicles is the power battery. The power battery used in electric vehicles mainly appears in the form of battery modules. The battery module is assembled by connecting multiple single cells in series and parallel and equipping corresponding control and protection components, which is convenient for installation and maintenance and can meet the usage requirements of the battery pack. The series and parallel combination of multiple single cells is realized through series-parallel busbars. The series-parallel busbars are generally made of metal materials such as copper, aluminum, and nickel.
[0003] In actual use, there are still many defects in the design of the battery nickel sheet structure. For example, the existing battery nickel sheet structure design is not convenient for preventing the incorrect assembly of the positive and negative poles of the cylindrical battery cells. At the same time, the existing battery nickel sheet structure design is not convenient for freely adjusting the positions of the positive and negative poles of the busbar. Therefore, a nickel sheet structure for 32 cylindrical batteries needs to be designed. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides a nickel sheet structure for 32 cylindrical batteries.
[0005] The utility model is realized by the following technical solutions: A nickel sheet structure for 32 cylindrical batteries includes 32 cylindrical battery cells, a first plastic bracket, and a second plastic bracket. A battery cell shell is arranged on the surface of the 32 cylindrical battery cells, and a welding pad is arranged on the surface of the battery cell shell. The two ends of the 32 cylindrical battery cells are fixedly connected with the first plastic bracket and the second plastic bracket. A first busbar is sleeved inside the first plastic bracket, and a positive nickel sheet is welded inside the first busbar. A second busbar is sleeved inside the second plastic bracket, and a negative nickel sheet is welded inside the second busbar.
[0006] Through the above technical solutions, by means of the groove punched out from the welding pad at the positive pole of the 32 cylindrical battery cells, when assembling the positive nickel sheet, the protruding part of the installation piece exactly corresponds to the groove of the positive welding pad. If the negative nickel sheet is assembled, it will protrude, and even if not discovered, it will cause poor soldering, and abnormal capacity will be found during testing, thus preventing the occurrence of incorrect positive and negative pole assembly.
[0007] By sleeving the first busbar and the second positioning hole inside the first plastic bracket and the second plastic bracket, the positions of the first busbar and the second busbar can be finely adjusted during the assembly process, which can facilitate the user to freely adjust the positions of the positive and negative poles of the first busbar and the second busbar.
[0008] As a further improvement of the above solution, a first positioning hole is formed inside the first bus bar, and a positive nickel sheet is welded to the inner wall of the first positioning hole.
[0009] Through the above technical solution, the positive nickel sheet can be conveniently welded inside the first bus bar through the first positioning hole.
[0010] As a further improvement of the above solution, a first welding hole is formed inside the positive nickel sheet, and the first welding hole is matched with the welding pad.
[0011] Through the above technical solution, the user can conveniently weld the positive nickel sheet on the surface of the welding pad through the first welding hole.
[0012] As a further improvement of the above solution, a second positioning hole is formed inside the second bus bar, and a negative nickel sheet is welded inside the second positioning hole.
[0013] Through the above technical solution, the negative nickel sheet can be conveniently welded inside the second bus bar through the second positioning hole.
[0014] As a further improvement of the above solution, a second welding hole is formed inside the negative nickel sheet, and the second welding hole is matched with the welding pad.
[0015] Through the above technical solution, the user can conveniently weld the negative nickel sheet on the surface of the welding pad through the second welding hole.
[0016] As a further improvement of the above solution, multiple groups of mounting pieces are formed inside the positive nickel sheet, and the mounting pieces correspond to the welding pads.
[0017] Through the above technical solution, by using the groove punched out from the welding pad at the positive pole of the 32 cylindrical battery cells, when assembling the positive nickel sheet, the protruding part of the mounting piece exactly corresponds to the groove of the positive welding pad. If the negative nickel sheet is assembled, it will protrude, which will cause false soldering even if not noticed, and abnormal capacity will be found during testing, thus preventing the occurrence of incorrect positive and negative assembly.
[0018] As a further improvement of the above solution, multiple groups of heat dissipation holes are formed inside the negative nickel sheet.
[0019] Through the above technical solution, the air circulation can be effectively increased through the heat dissipation holes, which helps to dissipate the heat generated during the operation of the battery.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0021] The utility model realizes the prevention of incorrect assembly of the positive and negative electrodes by the mutual cooperation among a battery cell housing, a welding pad, a first positioning hole, a positive nickel sheet, a first welding hole, a second positioning hole, a negative nickel sheet and a second welding hole. Through the groove punched out from the welding pad at the positive electrode of the 32-cylindrical battery cell, when assembling the positive nickel sheet, the protruding part of the mounting sheet exactly corresponds to the groove of the positive welding pad. If the negative nickel sheet is assembled, it will protrude, which will cause false soldering even if not detected, and abnormal capacity will be found in the test.
[0022] The utility model realizes the mutual cooperation among a first plastic bracket, a first bus bar, a positive nickel sheet, a second plastic bracket, a second bus bar and a negative nickel sheet. By sleeving the first bus bar and the second positioning hole inside the first plastic bracket and the second plastic bracket, the positions of the first bus bar and the second bus bar can be finely adjusted during the assembly process, which can facilitate the user to freely adjust the positions of the positive and negative electrodes of the first bus bar and the second bus bar.

The two ends of the 32-cylindrical battery cell 1 are fixedly connected to the first plastic bracket 2 and the second plastic bracket 3. A first bus bar 201 is sleeved inside the first plastic bracket 2, and a positive nickel sheet 203 is welded inside the first bus bar 201. A second bus bar 301 is sleeved inside the second plastic bracket 3, and a negative nickel sheet 303 is welded inside the second bus bar 301.
[0032] Through the groove punched out from the welding pad 102 at the positive pole of the 32-cylindrical battery cell 1, when assembling the positive nickel sheet 203, the protruding part of the mounting piece 205 exactly corresponds to the groove of the positive welding pad 102. If the negative nickel sheet 303 is assembled, it will protrude, which will cause a false soldering even if not discovered, and abnormal capacity will be found during testing, thus preventing the occurrence of wrong assembly of the positive and negative poles.
[0033] By sleeving the first bus bar 201 and the second positioning hole 302 inside the first plastic bracket 2 and the second plastic bracket 3, the positions of the first bus bar 201 and the second bus bar 301 can be finely adjusted during the assembly process, which can facilitate the user to freely adjust the positions of the positive and negative poles of the first bus bar 201 and the second bus bar 301.

By using the groove punched out from the welding pad 102 at the positive electrode of the 32-cylindrical battery cell 1, when assembling the positive nickel sheet 203, the protruding part of the mounting piece 205 exactly corresponds to the groove of the positive electrode welding pad 102. If the negative nickel sheet 303 is assembled, it will protrude, which will cause a virtual weld even if not detected, and abnormal capacity will be found during testing, thus preventing the occurrence of incorrect positive and negative electrode assembly.
[0047] By sleeving the first bus bar 201 and the second positioning hole 302 inside the first plastic bracket 2 and the second plastic bracket 3, the positions of the first bus bar 201 and the second bus bar 301 can be finely adjusted during the assembly process, which can facilitate users to freely adjust the positions of the positive and negative electrodes of the first bus bar 201 and the second bus bar 301.
