[0026] Please refer to Figures 1-3 , a sealing wiring device for an energy storage lithium battery pack, comprising a base 1, a cover plate 2, a clamping and sealing assembly, and a locking assembly. A storage groove is provided inside the base 1, the cover plate 2 is hingedly connected to one side of the base 1, a clamping and sealing assembly is provided inside the base 1, and a locking assembly is provided inside the cover plate 2;
[0027] The locking component includes two clamping plates 3 and a sealing ring 8. The two clamping plates 3 are distributed on the opposite sides inside the base 1, and the sealing ring 8 is arranged at the front opening of the base 1;
[0028] The design of multiple groups of springs 10 enables the clamping plates 3 to ensure the stability and sealing of the circuit of the clamped energy storage lithium battery pack.
[0029] In this embodiment, multiple groups of springs 10 are bolt - fixed between the side of the two clamping plates 3 facing the inner wall of the base 1 and the inner wall of the base 1. On the other side of the two clamping plates 3, a plurality of rubber blocks 4 are arranged in an array.
[0030] It should be noted that the design of the rubber blocks 4 not only enhances the friction between the clamping plates 3 and the circuit, but also improves the clamping stability.
[0031] In this embodiment, sliders 5 are arranged at both ends of the two clamping plates 3, and chutes 6 are opened at the corresponding positions inside the base 1. The sliders 5 are slidably connected to the chutes 6.
[0032] It should be noted that the matching design of the sliders 5 and the chutes 6 enables the clamping plates 3 to slide smoothly inside the base 1, ensuring that the clamping plates 3 can be evenly stressed during the clamping process, and improving the clamping accuracy and stability.
[0033] In this embodiment, insertion posts 7 are arranged at the four corners of the base 1 close to the storage slot and are inserted into the sealing ring 8 through the insertion posts 7. Fixed holes 9 are opened at the corresponding positions on the inner wall of the cover plate 2.
[0034] It should be noted that the insertion structure of the insertion posts 7 and the sealing ring 8, together with the design of the fixed holes 9, jointly constitute a tight sealing structure when the device is closed. This design ensures the sealing performance of the device in the closed state and effectively prevents the influence of external factors on the battery pack.
[0035] The locking component includes a push block 12 and a transverse lock block 14. The push block 12 is inserted into the cover plate 2 and one end of it is welded to the transverse lock block 14. A baffle is arranged outside the push block 12, and a small spring 13 is arranged between the baffle and the outer wall of the cover plate 2.
[0036] In this embodiment, an insertion hole 11 is opened on the front side of the base 1. The middle part of the insertion hole 11 is a cylindrical hole, and the front side is a longitudinal hole. The depth of the longitudinal hole is less than that of the cylindrical hole, and after the depth of the cylindrical hole exceeds that of the longitudinal hole, its diameter is directly widened to exceed the length of the longitudinal hole. A transverse hole is also opened inside the cylindrical hole at the place where it starts to widen.
[0037] It should be noted that the special design of the insertion hole 11 is for cooperation with the transverse lock block 14 in the locking assembly. When the transverse lock block 14 rotates and inserts into the insertion hole 11, it can first pass through the longitudinal hole, and then rotate inside the cylindrical hole and engage with the transverse hole, thereby realizing the locking of the device. This design not only ensures the stability of the locking but also improves the convenience of operation.
[0038] In this embodiment, a round cake groove 15 is also formed on the inner wall of the cover plate 2 and abuts against the transverse lock block 14. After the transverse lock block 14 rotates by ninety degrees, it is inserted into the insertion hole 11.
[0039] It should be noted that the design of the round cake groove 15 is for cooperation with the transverse lock block 14. When the transverse lock block 14 is in the unlocked state, it is abutted by the round cake groove 15 to prevent the push block 12 from falling. When the user needs to lock the device, just operate the push block 12 to rotate the transverse lock block 14 and insert it into the insertion hole 11, thereby realizing the locking of the device. This design makes the locking process simple, fast, safe and reliable.
[0040] Beneficial effects:
[0041] For the sealed wiring device for the energy storage lithium battery pack, the cover plate 2 is connected to the base 1 through a hinge, which is convenient for opening and closing operations. The clamping and sealing assembly includes two clamping plates 3 and a sealing ring 8. The clamping plates 3 firmly clamp the energy storage lithium battery pack by the elastic force of the spring 10. The setting of the rubber block 4 enhances the clamping stability and provides a good sealing effect. At the same time, the sliding connection design of the slider 5 and the chute 6 enables the clamping plate 3 to move smoothly inside the base 1, ensuring the uniformity and accuracy of clamping. The sealing ring 8 realizes the tight sealing when the device is closed through the insertion structure of the insertion post 7 and the base 1 and the fixed holes on the inner wall of the cover plate 2. The design of the locking assembly further enhances the safety of the device. The welding structure of the push block 12 and the transverse lock block 14 enables the user to easily lock or unlock the device through the operation of the push block 12. When locking is required, just rotate the push block 12 to drive the lock block 14 to rotate by ninety degrees, then push the push block 12 to insert the lock block 14 to the end of the cylindrical hole inside the insertion hole. After rotating the push block 12 in the reverse direction to restore it, the lock block 14 is stuck with the transverse hole, and under the elastic force of the small spring 13, the lock block 14 is always pulled to be stuck with the transverse hole to ensure the stability of the engagement.
