Detailed Implementation

[0023] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0024] Please see Figure 1 and Figure 2 This utility model provides a sulfur-based semi-solid lithium battery, including a shell 1, a fixing seat 2 on the side of the shell 1, a battery pack 3 inside the shell 1, a shell cover 4 fixed on the shell 1, and the shell cover 4 connected to the fixing seat 2 by bolts to fix the shell cover 4 on the shell 1 and protect the battery pack 3. The battery pack 3 is a lithium battery that combines sulfur cathode material and semi-solid electrolyte technology. An installation structure 5 is provided in the shell 1.

[0025] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a sulfur-based semi-solid lithium battery. The mounting structure 5 includes a mounting base 51. The mounting base 51 is fixed at the inner corner of the outer shell 1. A connecting plate 52 is provided on the mounting base 51. The connecting plate 52 is provided with a first screw hole 53 and a second screw hole 54. There are two of each of the first screw hole 53 and the second screw hole 54, and they are arranged symmetrically. The mounting base 51 is provided with a placement groove 55, and the battery pack 3 is provided with a placement opening 56. The depth of the placement groove 55 is the same as the depth of the placement opening 56. The size of the connecting plate 52 is adapted to the size of the placement groove 55.

[0026] Specifically, after placing the battery pack 3 inside the housing 1, the connecting plate 52 is placed in the placement slot 55 and the placement opening 56. Then, screws are connected to the battery pack 3 and the mounting base 51 through the first screw hole 53 and the second screw hole 54 respectively, so as to fix the connecting plate 52 on the battery pack 3 and to the mounting base 51. Since the size of the connecting plate 52 is compatible with the size of the placement slot 55 and the placement opening 56, fixing the connecting plate 52 can prevent shaking, so as to achieve high firmness after the connecting plate 52 is installed. At the same time, the battery pack 3 will press against the surface of the mounting base 51, effectively suppressing the shaking of the battery pack 3, thereby ensuring the stability of the battery pack 3 after installation.

[0027] The mounting base 51 has a positioning port 57, and the bottom of the connecting plate 52 is integrally formed with a positioning block 58. When the connecting plate 52 is placed in the placement groove 55, the positioning block 58 can be inserted into the positioning port 57 to make the screw holes aligned and to hold the connecting plate 52 in place, so as to prevent the connecting plate 52 from shaking.

[0028] The connecting plate 52 is provided with a top pressing structure 59, which includes a fixing groove 591. The connecting plate 52 has a fixing groove 591, and a fixing plate 592 is integrally formed in the fixing groove 591. A locking screw 593 is threadedly connected to the fixing plate 592.

[0029] A top block 594 is assembled in the fixing groove 591. The top block 594 is slidably connected to the fixing plate 592. A sliding groove 595 is provided on the top block 594. A locking screw 593 is located in the sliding groove 595. A spring 596 is installed in the top block 594. One end of the spring 596 is fixed to the fixing plate 592, and the other end of the spring 596 is fixed inside the top block 594. The spring 596 is in a compressed state. A support plate 597 is provided inside the fixing groove 591. The top block 594 is located on the upper end of the support plate 597, which can support the top block 594 and prevent it from tilting.

[0030] Specifically, rotating the locking screw 593 moves it upward, thereby releasing the limit on the top block 594. Since the spring 596 is in a compressed state, the top block 594 will press against the surface of the battery pack 3 under the action of the spring 596. Then, rotating the locking screw 593 limits the top block 594. Under the pushing of the top block 594, the shaking of the battery pack 3 is better suppressed, ensuring the firmness of the battery pack 3.

[0031] The battery pack 3 is installed inside the housing 1 through the mounting structure 5. The connecting plate 52 is placed in the placement slot 55 and the placement opening 56. The connecting plate 52 is fixed to the battery pack 3 with screws and fixed to the mounting base 51. After fixing, it can prevent shaking, so as to achieve high firmness after the connecting plate 52 is installed. At the same time, the battery pack 3 will abut against the surface of the mounting base 51, effectively suppressing the shaking of the battery pack 3, thereby ensuring the stability of the battery pack 3 after installation. Under the action of the spring 596, the top block 594 will abut against the surface of the battery pack 3. Then, the locking screw 593 is rotated to limit the top block 594. Under the pushing of the top block 594, the shaking of the battery pack 3 is better suppressed, ensuring the firmness of the battery pack 3. This achieves the beneficial effect of high firmness and good stability after the battery pack 3 is installed.
