Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a fixture for testing solid-state batteries. Background Technology

[0002] Vibration tests are required during the design and production of solid-state batteries to verify the rationality of the solid-state battery structure and prevent leakage, deformation, and other issues caused by vibration.

[0003] Currently, the fixture for vibration testing of solid-state batteries uses a pressure plate to press the battery onto a vibration table. The pressure plate is fixed to the vibration table by screws, and the pressure plate and screws are connected by bolts. In this connection method, the clamping force is applied by the operator by tightening the bolts. This clamping force is difficult to control. For example, a person with strong strength may apply excessive clamping force, damaging the battery, while a person with less strength will usually apply insufficient clamping force. Moreover, this structure usually requires a specific type of wrench for fixing the battery, which can be time-consuming for some operators who are not accustomed to finding a wrench. Therefore, this application proposes a fixture for testing solid-state batteries. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for testing solid-state batteries, so as to solve the problem of poor clamping force control during vibration testing of solid-state batteries.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0033] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a solid-state battery testing fixture, the fixture comprising:

[0036] Pressure plate 10, with first rotating sleeves 11 at both ends of the pressure plate 10, the first rotating sleeves 11 being cylindrical with openings at both ends;

[0037] A tightening sleeve 20 is rotatably connected to the first rotating sleeve 11. The end face of the tightening sleeve 20 away from the first rotating sleeve 11 is provided with a continuous first loosening surface 21, a first tightening surface 22, and a first clamping surface 23. The first loosening surface 21 and the first clamping surface 23 are both planes. The first tightening surface 22 is an inclined surface connecting the first loosening surface 21 and the first clamping surface 23. At least two of the first loosening surface 21, the first tightening surface 22, and the first clamping surface 23 are provided. The first loosening surface 21, the first tightening surface 22, and the first clamping surface 23 are evenly distributed around the axis of the tightening sleeve 20 in the circumferential direction. A handle 24 is provided on the tightening sleeve 20 for rotating the tightening sleeve 20. A positioning post 12 is also provided on the pressure plate 10.

[0038] The positioning sleeve 30 is a cylindrical sleeve with openings at both ends. The side of the positioning sleeve 30 that cooperates with the first loosening surface 21 is provided with a second loosening surface 31, a second tightening surface 32 and a second clamping surface 33 to respectively fit the first loosening surface 21, the first tightening surface 22 and the first clamping surface 23.

[0039] In this embodiment, when clamping the battery using the fixture described herein, the pressure plate 10, the tightening sleeve 20, and the positioning sleeve 30 are fitted onto the screw. The pressure plate 10 presses against the battery. A nut is placed at the end of the tightening sleeve 20 away from the pressure plate 10. The nut does not need to be tightened. When the tightening sleeve 20 is not tightened, the first loosening surface 21 and the second loosening surface 31 cooperate, the first tightening surface 22 and the second tightening surface 32 cooperate, and the first clamping surface 23 and the second clamping surface 33 cooperate. When the tightening sleeve 20 is tightened, the first clamping surface 23 rotates along the second tightening surface 32 to the second loosening surface 31, causing the tightening sleeve 20 and the positioning sleeve 30 to move away from each other. Since the positioning sleeve 30 does not move on the screw due to the obstruction of the nut, the tightening sleeve 20 presses against the pressure plate 10. The first clamping surface 23 rotates to the positioning post 12, and the tightening sleeve 20 and the positioning sleeve 30 move a preset distance, making the clamping force controllable. At the same time, rotating the tightening sleeve 20 does not require additional tools.

[0040] The solid-state battery testing fixture disclosed in this embodiment of the utility model is equipped with a tightening sleeve 20 and a positioning sleeve 30. After rotating a preset angle, the tightening sleeve 20 and the positioning sleeve 30 move away from each other by a preset distance. When the positioning sleeve 30 is blocked by the nut on the screw, the force of the tightening sleeve 20 pressing the pressure plate 10 is controllable, thereby making the clamping force of the battery controllable. At the same time, the tightening sleeve 20 is provided with a handle 24, so that no additional tools are required when fixing the battery.

[0041] Specifically, in this embodiment, such as Figure 3 As shown, the pressure plate 10 is a flat plate structure, and the edge of the pressure plate 10 is provided with a first reinforcing rib to strengthen the strength of the pressure plate 10. The first rotating sleeve 11 is a cylindrical structure provided at the end of the pressure plate 10, and the first rotating sleeve 11 and the pressure plate 10 are an integral structure.

[0042] The positioning post 12 is a cylindrical structure fixed to the pressure plate 10.

[0043] In a preferred embodiment of this invention, the pressure plate 10 is further provided with a limiting post 13. The limiting post 13 is a cylindrical structure and is detachably connected to one side of the positioning post 12 via a thread. When the tightening sleeve 20 rotates by a preset angle, the limiting post 13 and the positioning post 12 are located on both sides of the handle 24. The positioning post 12 is fixed to the pressure plate 10 by an interference fit.

[0044] like Figure 4As shown, the tightening sleeve 20 has a cylindrical structure. The first tightening surface 22 and the first clamping surface 23 are protrusions at the ends of the tightening sleeve 20. The first tightening surface 22 is a plane, and the first clamping surface 23 is an inclined surface. The handle 24 is fixed to the side of the tightening sleeve 20 by a threaded structure.

[0045] like Figure 5 As shown, the positioning sleeve 30 is a cylindrical shape with openings at both ends. The structure of the second tightening surface 32 and the second clamping surface 33 is the same as that of the first tightening surface 22 and the first clamping surface 23. The first loosening surface 21, the first tightening surface 22, the first clamping surface 23, the second loosening surface 31, the second tightening surface 32, and the second clamping surface 33 are all provided in twos.

[0046] Example 2

[0047] like Figure 1 and Figure 2 As shown, as another embodiment of this utility model, the difference between this embodiment and embodiment 1 is that the clamp further includes:

[0048] Limiting component 40 is used to limit the positioning sleeve 30.

[0049] Preferably, in this embodiment, the limiting component 40 includes:

[0050] The second rotating sleeve 41 is a cylindrical shape with openings at both ends, and the positioning sleeve 30 is slidably connected to the second rotating sleeve 41.

[0051] At least two conical clamping blocks 42 are fixedly connected to the inner side of the second rotating sleeve 41. The outer side of the conical clamping block 42 is a conical surface, and the inner side of the conical clamping block 42 is a threaded surface. Multiple conical clamping blocks 42 form a conical nut, and an elastic element is provided between adjacent conical clamping blocks 42.

[0052] A clamping sleeve 43 is fixedly connected to the inner side of the second rotating sleeve 41. The inner side of the clamping sleeve 43 that is in contact with the conical clamping block 42 is conical. When the conical clamping block 42 moves toward the center of the clamping sleeve 43, adjacent conical clamping blocks 42 move closer to each other. The end of the conical clamping block 42 away from the clamping sleeve 43 abuts against the end of the positioning sleeve 30.

[0053] Spring positioning sleeve 45, the two ends of which respectively abut against the end of the conical clamping block 42 away from the positioning sleeve 30 and the second rotating sleeve 41;

[0054] In this embodiment, as Figure 6 and Figure 7As shown, two conical clamping blocks 42 are provided. Each conical clamping block 42 is half of a conical nut. The elastic element is a spring structure. A spring hole is provided on the interconnecting side of each conical clamping block 42. The spring hole is a blind hole. The clamping sleeve 43 is threadedly connected to the second rotating sleeve 41. A spring 44 is threadedly connected to the inner side of the clamping sleeve 43. Both ends of the spring positioning sleeve 45 abut against the spring 44 and the conical clamping block 42. The end of the second rotating sleeve 41 that mates with the positioning sleeve 30 has a hexagonal opening. The outer side of the 30 is a hexagonal prism structure. The end of the positioning sleeve 30 that cooperates with the conical clamping block 42 is provided with an outer retaining ring 34. The outer diameter of the outer retaining ring 34 is larger than the diameter of the circumscribed circle of the positioning sleeve 30. When the tightening sleeve 20 rotates, the tightening sleeve 20 and the positioning sleeve 30 move away from each other. The tightening sleeve 20 presses against the pressure plate 10. The positioning sleeve 30 lifts up the conical clamping block 42. The conical clamping blocks 42 slide and move closer to each other in the clamping sleeve 43. The conical clamping blocks 42 clamp the screw, thereby fixing the limiting component 40 to the screw.

[0055] In a preferred embodiment of this invention, two limiting components 40 are provided, and the two limiting components 40 are connected by a connecting plate 46. The connecting plate 46 and the second rotating sleeve 41 are an integral structure.

[0056] Preferably, the pressure plate 10 is further provided with a guide rod 14, which passes through the connecting plate 46 and is slidably connected to the connecting plate 46. A nut is provided at the end of the guide rod 14 away from the connecting plate 46.

[0057] It should be noted that in this embodiment, the limiting component 40 can also be a nut. However, when the limiting component 40 is fitted with a nut, it needs to be screwed in, which is not as convenient as in this embodiment.
