[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a housing frame structure for a solid-state battery, such as... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a housing 1, a cover 2 movably connected to the top of the housing 1, connecting plates 3 fixedly connected to both sides of the housing 1, connecting posts 4 fixedly connected to the top of the connecting plates 3, connecting shells 5 fixedly connected to both sides of the cover 2, a base plate 6 fixedly connected to the bottom of the connecting shells 5, an insert 7 fixedly connected to the center of the base plate 6, the bottom of the base plate 6 fitting against the top of the connecting plates 3, the connecting posts 4 inserted into the interior of the insert 7, a fixing block 8 fixedly connected to one inner wall of the connecting shell 5, a telescopic rod 9 fixedly connected to one side of the fixing block 8, a locking block 11 fixedly connected to the movable end of the telescopic rod 9, and a through groove 12 opened on the side surface of the insert 7.

[0025] The side surface of the connecting column 4 is provided with a slot 13. The end of the locking block 11 away from the telescopic rod 9 extends through the through groove 12 into the inside of the insert 7 and is locked inside the slot 13.

[0026] A first spring 10 is fitted on the side surface of the telescopic rod 9. One end of the first spring 10 is fixedly connected to the side of the fixing block 8 near the telescopic rod 9, and the other end of the first spring 10 is fixedly connected to the end of the locking block 11 near the telescopic rod 9.

[0027] When the cover 2 is fastened onto the housing 1, the connecting post 4 on the connecting plate 3 can be inserted into the inside of the insert 7. When the connecting post 4 is inserted into the inside of the insert 7, it will contact the locking block 11. As the connecting post 4 is continuously inserted, the connecting post 4 will squeeze the locking block 11 to move it and compress the first spring 10. The telescopic rod 9 can automatically extend and retract when the locking block 11 moves to cooperate with the locking block 11 and improve the stability of the locking block 11 when it moves. When the slot 13 on the side surface of the connecting post 4 moves to the locking block 11, the first spring 10 will release the pressure and push the locking block 11 to move, so that the locking block 11 is inserted into the inside of the slot 13, restricting the connecting post 4, thereby allowing the cover 2 to be fixed together with the housing 1.

[0028] Furthermore, to facilitate maintenance or replacement work by staff, such as Figure 2 , Figure 3 and Figure 4 As shown, a sealing plate 14 is fixedly connected inside the connecting shell 5, a pressure block 15 is slidably connected to the side surface of the insert 7, the side surface of the pressure block 15 is slidably attached to the inner wall of the sealing plate 14, an extrusion strip 16 is fixedly connected to the bottom of the pressure block 15, and a traction block 17 is fixedly connected to one end of the locking block 11 near the telescopic rod 9, the side surface of the traction block 17 is attached to the side surface of the extrusion strip 16.

[0029] When performing maintenance or replacement work, the staff needs to open the cover 2. When opening the cover 2, the pressure block 15 can be pressed. The pressure block 15 can drive the extrusion strip 16 to move down. The extrusion strip 16 is trapezoidal, and its hypotenuse is matched with the traction block 17. Therefore, when the extrusion strip 16 moves vertically, it can drive the traction block 17 to move horizontally, thereby causing the traction block 17 to drive the locking block 11 to retract, so that the connecting column 4 can be released, thereby releasing the fixed state between the cover 2 and the housing 1. At this time, the staff can remove the cover 2 from the housing 1.

[0030] It should be noted that in order for the pressure block 15 to automatically reset, such as Figure 2 , Figure 3 and Figure 4 As shown, a reset plate 18 is slidably connected to the side surface of the insert 7. The top of the reset plate 18 is fixedly connected to the bottom of the extrusion strip 16. A second spring 19 is sleeved on the side surface of the insert 7. The top of the second spring 19 is fixedly connected to the bottom of the reset plate 18, and the bottom of the second spring 19 is fixedly connected to the top of the base plate 6.

[0031] When the pressure block 15 moves down, it can compress the second spring 19 through the extrusion bar 16 and the reset plate 18. When the force applied to the pressure block 15 disappears, the rebound force of the second spring 19 can push the reset plate 18, the extrusion bar 16 and the pressure block 15 to reset.

[0032] Furthermore, to improve the stability of the cover 2 when it is fixed to the housing 1, such as... Figure 1 and Figure 2 As shown, a rubber ring 20 is fixedly connected inside the shell cover 2. The bottom of the rubber ring 20 is in contact with the top of the shell 1. Several partitions 21 are fixedly connected inside the shell 1.

[0033] When the cover 2 is fastened onto the housing 1, the top of the housing 1 will compress the rubber ring 20. The rubber ring 20 will deform under the force so that the locking block 11 can be smoothly inserted into the slot 13. At the same time, the rubber ring 20 will also exert a reaction force on the housing 1 and push the housing 1 at all times, thereby effectively enhancing the firmness between the cover 2 and the housing 1. The partition 21 is set to divide the internal space of the housing 1, which improves the safety of the solid-state battery during installation and use.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
