[0026] In the present application, the provision of two heat sinks 2 improves the heat dissipation efficiency of the collector housing 101 and avoids heat generation due to excessive resistance, thereby damaging the collector structure 1.
[0027] Furthermore, fixing holes 8 are provided on both upper and lower sides of each end of the collector housing 101 , and four limiting grooves 9 are provided on the outer surface of each end of the collector housing 101 , and the fixing hole 8 is located in the middle of the limiting grooves 9 .
[0028] In the present application, the setting of the fixing hole 8 makes it easy for the limit frame 1022 to be inserted into the collector housing 101, so that the spring piece 1023 can pass through the fixing hole 8, thereby fixing the collector end cover 102; the setting of the limit groove 9 provides a limit space for the limit bar 1024.
[0029] Furthermore, each collector end cover 102 includes a sealing cover 1021, and a limiting frame 1022 is fixedly connected to the inner side of each sealing cover 1021. The inner side of the sealing cover 1021 abuts against the collector outer shell 101, and the limiting frame 1022 is inserted into the collector outer shell 101. Both sides of the outer surface of each limiting frame 1022 are fixedly connected with spring pieces 1023, and the spring pieces 1023 are adapted to the fixing holes 8. Four limiting bars 1024 are fixedly installed on the inner side of each sealing cover 1021, and the limiting bars 1024 are adapted to the limiting grooves 9.
[0030] In the present application, when the collector end cover 102 is installed with the collector housing 101, the spring piece 1023 is first pressed, and then each limiting strip 1024 on the cover 1021 is aligned with each limiting groove 9 respectively, and then the limiting frame 1022 is inserted into the collector housing 101. When the spring piece 1023 is aligned with the fixing hole 8, the pressure on the spring piece 1023 is released. At this time, the spring piece 1023 is reset, and then the spring piece 1023 is made to pass through the fixing hole 8 to complete the fixation of the collector end cover 102.
[0031] Furthermore, an outer sealing ring 4 is fixedly connected to the inner wall of each limiting frame 1022 , an inner sealing ring 5 is interference-fitted inside each outer sealing ring 4 , and the two inner sealing rings 5 are fixedly sleeved on both ends of the battery body 6 .
[0032] In the present application, the battery body 6 is first placed in the collector housing 101, and then the two collector end caps 102 are fixedly installed with the collector housing 101. During the installation process, as the limit frame 1022 enters, the inner sealing ring 5 will be along the inner wall of the outer sealing ring 4 and have an interference fit with the outer sealing ring 4. The interference fit between the inner sealing ring 5 and the outer sealing ring 4 improves the stability of the battery body 6 and prevents the battery body 6 from shaking in the collector housing 101.
[0033] Furthermore, electrodes 7 are provided at both ends of the battery body 6 , and a threading hole 10 is provided on each cover 1021 corresponding to each electrode 7 , and the fixing structure 3 is fixedly installed in the threading hole 10 .
[0034] Furthermore, each fixing structure 3 includes a conical screw sleeve 301 , which is fixedly installed in the threading hole 10 , and a nut 302 is threadedly connected to each conical screw sleeve 301 .
[0035] In the present application, in order to improve the stable connection between the collector structure 1 and other parts, the fixing structure 3 is set up so that the data cable of the external part passes through the conical screw sleeve 301 and the threading hole 10 to be connected to the electrode 7, and finally the nut 302 is threadedly connected to the conical screw sleeve 301 to complete the fixation of the data cable.
[0036] Furthermore, the collector housing 101 includes a collector substrate 1011 , a conductive coating 1012 and an insulating layer 1013 from the inside to the outside. The conductive coating 1012 is located on the outer surface of the collector substrate 1011 , and the insulating layer 1013 is located on the outer surface of the conductive coating 1012 .
[0037] In the present application, the collector substrate 1011 is made of a material with good conductive properties, such as metal (such as copper, aluminum, etc.) or a conductive composite material. In addition, the setting of the conductive coating 1012 improves the conductivity of the collector structure 1. At the same time, the setting of the insulating layer 1013 avoids short circuit between the collector structure 1 and other parts.
[0038] The working principle of this utility model:
[0039] When in use, first place the battery body 6 in the collector housing 101, then press the spring piece 1023, align each limit strip 1024 on the cover 1021 with each limit groove 9, then insert the limit frame 1022 into the collector housing 101. As the limit frame 1022 enters, the inner sealing ring 5 will be along the inner wall of the outer sealing ring 4 and have an interference fit with the outer sealing ring 4. When the spring piece 1023 is aligned with the fixing hole 8, release the pressure on the spring piece 1023. When the spring piece 1023 is reset, the spring piece 1023 is made to pass through the fixing hole 8, thereby completing the fixation of the collector end cover 102. In order to improve the stability of the connection between the collector structure 1 and the external parts, the data line of the external parts is connected to the electrode 7 through the setting of the fixing structure 3, and finally the nut 302 is threadedly connected with the conical screw sleeve 301, thereby completing the fixation of the data line, thereby improving the stable connection between the collector structure 1 and the external parts;
[0040] The collector substrate 1011 is made of a material with good conductive properties, such as metal (such as copper, aluminum, etc.) or a conductive composite material. In addition, the setting of the conductive coating 1012 improves the conductivity of the collector structure 1. At the same time, the setting of the insulating layer 1013 avoids short circuit between the collector structure 1 and other parts.
[0041] To sum up: this new energy battery pack adopts a collector structure, which improves the heat dissipation efficiency of the collector shell 101 through the setting of two heat sinks 2, and avoids the heat generated by excessive resistance, thereby damaging the collector structure 1; through the interference fit of the inner sealing ring 5 and the outer sealing ring 4, the stability of the installation of the battery body 6 is improved, and the shaking of the battery body 6 in the collector shell 101 is avoided; through the setting of the fixing structure 3, the data cable of the external part is passed through the conical screw sleeve 301 and the threading hole 10 to be connected with the electrode 7, and finally the nut 302 is threadedly connected with the conical screw sleeve 301, thereby completing the fixation of the data cable and improving the stable connection between the external part and the collector structure 1.
