During production, the two need to be assembled together before proceeding to the next process. The tear strip on the side of the riveting block is exposed, and during assembly and subsequent processes, it is easy to scrape the tear strip and generate free metal shavings, which contaminate the product. In addition, during the processing, the aluminum block needs to be stamped and the upper plastic needs to be injected first. The subsequent assembly process also requires assembling the aluminum block and the upper plastic, which is cumbersome and has low production efficiency. Utility Model Content

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0020] This utility model embodiment provides a novel riveted structure top cover, such as Figure 1-3 As shown, the novel riveted structure top cover includes: a riveting block 10, with a tear strip 102 on one side of the riveting block 10; a secondary stepped surface 101 on the riveting block 10; an upper plastic 20 on the riveting block 10, which is adapted to the secondary stepped surface 101 of the riveting block; a light aluminum sheet 30 mounted on the riveting block 10; and a pole post 50 installed on the riveting block 10, with all sub-components between the riveting block 10 and the pole post 50 fixed.
[0021] In this embodiment, after the riveting block 10 is wrapped with plastic 20, the riveting block 10 and the plastic 20 become a whole. The plastic 20 can cover the tear strip 102 of the riveting block, avoiding the scraping of the tear strip 102 of the riveting block in subsequent processes, thereby avoiding the generation of free metal shavings and contamination of the product, thus improving the product appearance yield. At the same time, after the riveting block 10 is wrapped with plastic 20, the assembly process does not need to reassemble the two, reducing assembly time and improving production efficiency. The secondary step surface 101 of the riveting block can improve the stability of the connection between the riveting block 10 and the plastic 20, preventing the plastic 20 from falling off. The aluminum sheet 30 can effectively transmit and distribute the current between the battery cells, ensuring the normal operation of the battery pack. The terminal 50 is a key component for connecting the internal and external circuits of the battery. It ensures that the charging and discharging current of the battery cells can be smoothly introduced and discharged, thereby realizing the normal operation of the battery.
[0022] In a further preferred embodiment of the present invention, the tear strip 102 of the rivet block is formed by the stamping process of the rivet block 10, and the secondary step surface 101 of the rivet block is lower than the upper surface of the rivet block 10.
[0023] In this embodiment, the secondary step surface 101 of the rivet block is lower than the upper surface of the rivet block 10, and the secondary step surface 101 of the rivet block mates with the upper plastic 20, thereby improving the stability of the connection between the rivet block 10 and the upper plastic 20, and preventing the upper plastic 20 from falling off.
[0024] In a further preferred embodiment of this utility model, the upper plastic 20 is located between the riveting block 10 and the light aluminum sheet 30.
[0025] In this embodiment, by placing the upper plastic 20 between the rivet block 10 and the light aluminum sheet 30, the electrical performance of the cover plate is prevented from being poor after the rivet block 10 and the light aluminum sheet 30 come into direct contact.
[0026] In a further preferred embodiment of the present invention, a sealing ring 40 is provided on the pole post 50, and the sealing ring 40 is located between the aluminum sheet 30 and the pole post 50.
[0027] In this embodiment, the sealing ring 40 can improve the overall sealing performance during use.
[0028] In a further preferred embodiment of this utility model, a lower plastic 60 is provided below the riveting block 10.
[0029] In this embodiment, the lower plastic 60 can improve the overall sealing performance during use, preventing battery fluid leakage, and can also improve the overall insulation performance during use, preventing current leakage and improving the overall stability of the battery during use.
[0030] In a further preferred embodiment of the present invention, a pressure relief valve 103 is provided on the riveting block 10, the pressure relief valve 103 is used to relieve pressure inside the battery, and a pressure sensor 104 is provided on the riveting block 10, the pressure sensor 104 is used to monitor the pressure inside the battery.
[0031] In this embodiment, a pressure sensor 104 is used to monitor the pressure inside the battery. When the pressure inside the battery reaches a certain value, the pressure sensor 104 sends a signal to the controller. The controller receives and recognizes the signal, and then the controller activates the pressure relief valve 103 to release the pressure inside the battery, thereby preventing dangerous situations such as battery explosion.
[0032] In a further preferred embodiment of the present invention, a controller is provided on the riveting block 10. The controller is adapted to the pressure relief valve 103 and the air pressure sensor 104, and the controller is used to perform control operations.
[0033] In this embodiment, the pressure sensor 104 and the pressure relief valve 103 are conveniently controlled by the controller. The working principle of the controller is existing technology and will not be described in detail here.
[0034] In summary, compared with related technologies, the top cover of the entire riveting structure can avoid the situation of scraping and tearing the riveting block 102 during subsequent processes, thereby avoiding the generation of free metal shavings and contamination of the product, thus improving the product appearance yield. Furthermore, it eliminates the need for secondary assembly of the riveting block 10 and the upper plastic 20, reducing assembly time and improving production efficiency.
