[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a solid-state battery pack, including: a battery pack outer shell 1 and a battery pack cover plate 2. The battery pack outer shell 1 is provided with the battery pack cover plate 2 at the top. The upper half of the outer wall of the battery pack outer shell 1 is provided with an outer shell flange 4. The bottom of the outer shell flange 4 is provided with a lower locking groove 13. The outer shell flange 4 provides support and positioning for the battery pack cover plate 2. The lower locking groove 13 is used to engage with the spring pin 12 on the adjusting plate 11 to lock and fix the battery pack, ensuring the stability of the battery pack during use.

[0023] The battery pack cover 2 has a rotating shaft 6 around its perimeter. A threaded rod 8 is fixed to the outer wall of the rotating shaft 6, and an adjusting plate 11 is located on the outer side of the threaded rod 8. The rotating shaft 6 allows the threaded rod 8 to rotate, facilitating the adjustment of the position of the adjusting plate 11. The threaded rod 8 provides downward pressure to the adjusting plate 11, which in turn applies pressure to the outer flange 4, thus locking the battery pack. A spring pin 12 is located at the top of the adjusting plate 11. Multiple spring pins 12 are evenly distributed circumferentially on the adjusting plate 11, with one spring pin 12 engaging with a lower locking groove 13. The design of the spring pins 12 allows the adjusting plate 11 to engage with the lower locking groove 13 on the outer flange 4, achieving the locking and securing of the battery pack. The even distribution of multiple spring pins 12 increases the stability and reliability of the engagement.

[0024] The battery pack cover 2 has cover grooves 5 around its perimeter on the outside of the rotating shaft 6. The two ends of the rotating shaft 6 are rotatably connected to the two ends of the cover grooves 5. The cover grooves 5 provide rotation space for the rotating shaft 6, allowing the threaded rod 8 to rotate smoothly, facilitating the adjustment of the position of the adjusting plate 11, and improving the installation efficiency of the battery pack.

[0025] The battery pack cover 2 has a handle 3 at the top and a handle 9 at the bottom of the threaded rod 8.

The handle 9 facilitates the rotation of the threaded rod 8, allowing the adjusting plate 11 to press down and lock the battery pack, further improving installation convenience.

[0026] The top surface of the outer flange 4 has an upper retaining groove that engages with the bottom of the battery pack cover 2. The adjusting plate 11 has a threaded hole in its center that mates with the threaded rod 8. The engagement between the upper retaining groove and the bottom of the battery pack cover 2 provides initial sealing and fixation of the battery pack, laying the foundation for subsequent locking and fixing. The threaded hole design allows the adjusting plate 11 to move up and down along the threaded rod 8, facilitating adjustment of the position of the adjusting plate 11 and the contact force with the outer flange 4.

[0027] The outer wall of the battery pack housing 1 is provided with a C-shaped clip 10, which is located on one side of the threaded rod 8 and can be engaged with the threaded rod 8. The C-shaped clip 10 engages and fixes the threaded rod 8 to prevent it from rotating freely during use, thus ensuring the stability of the battery pack's locked state.

[0028] When using a solid-state battery pack, during solid-state battery assembly, the battery pack cover plate 2 is placed on top of the battery pack outer shell 1. The battery pack is sealed and fixed by the snap-fit ​​between the bottom of the battery pack cover plate 2 and the top of the outer shell flange 4. Then, by pressing down and rotating the threaded rod 8, the adjusting plate 11 abuts against the outer shell flange 4. The spring pin 12 on the adjusting plate 11 snaps into the lower snap-fit ​​13, thus locking and fixing the battery pack. The C-clamp 10 snaps and fixes the threaded rod 8, preventing the threaded rod 8 from rotating freely. The threaded rod 8, in conjunction with the pressing and fixing of the adjusting plate 11, replaces the traditional thread fixing, greatly improving the installation efficiency of the battery pack.

[0029] Furthermore, during battery pack installation, the position of the adjusting plate 11 on the threaded rod 8 can be adjusted by finely rotating the adjusting plate 11, thereby adjusting the contact force between the adjusting plate 11 and the outer flange 4 to ensure proper installation force.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
