Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to an output pole base of a battery module. Background Art

[0002] A battery module usually includes an end plate and an output pole base. The end plate is used to compress multiple battery cells. The output pole base is installed on the end plate at the output end of the battery module and is used to connect the output pole connecting piece and provide insulation protection for the output pole connecting piece.

[0003] The existing patent (application number: CN202320808713.5) proposes an output pole base and a battery module, which includes a base body, which is used to fix a connecting plate; and a connecting component, which is connected to the base body, and the connecting component includes a fixing column and a fixing head, one end of the fixing column is connected to the base body, and the fixing head is connected to an end of the fixing column away from the base body, and the fixing head is provided with an assembly chamfer.

[0004] However, the above patent has certain defects. Although a connecting component is provided on the output pole base in the patent and can be installed on the end plate by insertion, the connecting component needs to be deformed and restored to its original state during the installation and removal of the output pole base. The connecting component is a rigid structure and has poor elasticity. If it is not operated properly, it is easy to cause the connecting component to break, thereby causing the connecting component to be unable to engage with the connecting hole, resulting in the output pole base being unable to be fixed or easily loosened. Therefore, the utility model provides a battery module output pole base. Utility Model Content

[0007] A battery module output pole base comprises an output pole base body and a battery module end plate, an insulating plate is fixedly installed on the bottom of the output pole base body, a cavity is penetrated on the front side of the insulating plate, a fixing plate is fixedly installed on the inner wall of the cavity, a spring is fixedly installed on the surface of the fixing plate, a limiting plate is fixedly installed on the surface of the spring, a guide component is arranged on the surface of the limiting plate, a positioning groove is opened on the top of the battery module end plate, a limiting groove is penetrated on the inner wall of the positioning groove, an installation groove is opened on the front side of the output pole base body, a protective cover is slidably connected inside the installation groove, and an installation component is arranged on the front side of the output pole base body.

[0008] Preferably, the guide assembly includes a guide rod disposed on the surface of the limiting plate, the guide rod is slidably connected to the fixing plate, and a connecting plate is fixedly mounted on the surface of the guide rod.

[0009] Preferably, the mounting assembly comprises a mounting plate arranged on the front side of the output pole base body, the mounting plate is internally threadedly connected with bolts, and the bolts are threadedly connected to the protective cover.

[0010] Preferably, a mounting hole is opened inside the output pole base body, and the number of the mounting holes is multiple.

[0011] Preferably, the insulating plate is matched with the positioning groove, and the limiting plate is matched with the limiting groove.

[0012] Preferably, the limiting plate is in a right-angled triangle structure and is made of insulating material.

[0013] Preferably, the guide rod is in a rectangular columnar structure, and there are multiple guide rods.

[0014] Compared with the prior art, the beneficial effect of the utility model is that when the output pole base of the battery module is installed, the limit plate will be squeezed during the process of inserting the insulating plate downward into the positioning groove, so that the limit plates are close to each other through the guide assembly, so that the spring is compressed. When the bottom of the output pole base body is in contact with the end plate of the battery module, the force generated by the compression of the spring just pushes the limit plate to be inserted into the limit groove. When disassembling, the limit plates are pushed from both ends of the limit groove, so that the limit plates are close to each other through the guide assembly, so that the spring is compressed until the limit plate is separated from the limit groove, and then the output pole base body can be pulled out. The spring is an elastic structure and is not easy to break, so that the installation and disassembly of the output pole base body can be completed more stably, avoiding the phenomenon that the output pole base body is easily unable to be fixed or loose.

A limiting plate 7 is fixedly installed on the surface of the spring 6. The limiting plate 7 is a right-angled triangle structure. The limiting plate 7 is made of insulating material, which is convenient for squeezing and pushing the limiting plates 7 to approach each other during installation, so that the installation of the output pole base body 1 can be completed more conveniently. A guide component is set on the surface of the limiting plate 7. A positioning groove 10 is opened at the top of the battery module end plate 2. A limiting groove 11 is set through the inner wall of the positioning groove 10. The insulating plate 3 is adapted to the positioning groove 10, and the limiting plate 7 is adapted to the limiting groove 11. An installation groove 12 is opened on the front side of the output pole base body 1. A protective cover 13 is slidably connected inside the installation groove 12, which is convenient for the battery module output The connection between the pole and the output pole base body 1 is protected, and an installation component is arranged on the front side of the output pole base body 1. When installing the battery module output pole base, in the process of inserting the insulating plate 3 downward into the positioning groove 10, the limit plate 7 will be squeezed, so that the limit plates 7 are close to each other through the guide component, so that the spring 6 is compressed. When the bottom of the output pole base body 1 is in contact with the battery module end plate 2, the force generated by the compression of the spring 6 just pushes the limit plate 7 to be inserted into the limit groove 11. When disassembling, the limit plates 7 are pushed from both ends of the limit groove 11, so that the limit plates 7 are close to each other through the guide component, so that the spring 6 is compressed until the limit plate 7 is separated from the limit groove 11, and then the output pole base body 1 can be pulled out. The spring 6 has an elastic structure and is not easy to break, so that the installation and disassembly of the output pole base body 1 can be completed more stably, avoiding the phenomenon that the output pole base body 1 is easy to be unable to be fixed or loose.
