[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 ,in, Figure 1 This is a schematic diagram of the overall structure of the easily adjustable lithium battery test bench provided by the utility model; Figure 2 A partial schematic diagram of the easily adjustable lithium battery test bench provided by the present invention; Figure 3 A schematic diagram of a fixing frame provided by the present utility model; Figure 4 This is a disassembled diagram of the fixing frame and the placement table provided by the utility model; Figure 5 This is a schematic diagram of the fixing frame provided by the utility model from another perspective.

[0023] In the specific implementation process, Figure 1-Figure 5 As shown, a lithium battery test bench that is easy to adjust includes a test bench body and a placement table 7 arranged on the test bench body. Two fixed frames 3 are provided on the placement table 7. One side of the two fixed frames 3 is connected to the placement table 7 through a driving device. The driving device is used to move the two fixed frames 3 to the same side or opposite sides. A placement cavity 12 is provided inside the two fixed frames 3. A limit device for fixing the lithium battery is provided inside the two fixed frames 3. The upper ends of the two fixed frames 3 are provided with a detection port for detecting the test bench body. Both detection ports are arranged in a semicircular arc shape. A plurality of locking universal wheels 4 are installed at the bottom of the fixing frame 1;

[0024] During specific use, two fixing frames 3 are provided, and a placement cavity 12 is provided inside the two fixing frames 3. During specific use, the two fixing frames 3 are moved in adjacent directions by the driving assembly, so that the lithium battery can enter the placement cavity 12 provided inside the two fixing frames 3. When the lithium battery enters the placement cavity 12, the lithium battery can be fixed by the limiting device inside the placement cavity 12. During use, the device can not only fix the lithium battery, but also protect the lithium battery through the setting of the placement cavity 12, so that the overall test process is safer;

[0025] The limiting device includes two limiting plates 5, the edges of the adjacent sides of the two limiting plates 5 are set to be arc-shaped, the upper ends of the two limiting plates 5 are fixedly connected to the connecting plates 6, and the two connecting plates 6 are movably arranged in the sliding grooves provided in the placement cavity 12. The opposite sides of the two connecting plates 6 are fixedly connected to springs 11, and the opposite ends of the two springs 11 are respectively fixedly connected to the opposite sides of the sliding grooves;

[0026] The specific use process of the above-mentioned limiting device is as follows: first, when the lithium battery enters the interior of the placement cavity 12, it will first contact the adjacent sides of the two limiting plates 5. Since the edges of the adjacent sides of the two limiting plates 5 are set to be arc-shaped, the lithium battery squeezes the two limiting plates 5, causing the two limiting plates 5 to move in opposite directions. During this process, the spring 11 is compressed until the lithium battery completely enters the position between the two limiting plates 5. Then, the pushing force of the spring 11 allows the two limiting plates 5 to fit against the outer wall of the lithium battery, thereby achieving the effect of fixing the lithium battery.

[0027] The test bench includes a fixing frame 1, a placement table 7, and an impact body 2. The placement table 7 is installed inside the fixing frame 1, and the impact body 2 is installed above the placement table 7. The upper end of the impact body 2 is installed on the upper side of the fixing frame 1.

[0028] The impact body 2 generally includes an impact head, a take-up reel, and a cable. When in use, after the take-up reel releases the cable, the impact head moves downward due to gravity, causing the lithium battery to be impacted.

[0029] The driving device includes a threaded rod 8 and a sliding block 10. Two sliding blocks 10 are provided. The two sliding blocks 10 are movably arranged in motion grooves provided on the opposite inner side walls of the placement table 7. The adjacent sides of the two sliding blocks 10 are fixedly connected to the opposite sides of the placement table 7. The threaded rod 8 passes through one of the sliding blocks 10. One end of the threaded rod 8 is fixedly connected to the rotating disk 9.

[0030] Among them, the specific usage of the above-mentioned driving device is as follows: by rotating the threaded rod 8, the lithium battery can enter the placement cavity 12 set inside the two fixed frames 3, and the above-mentioned threaded rod 8 is a bidirectional screw.

[0031] The working principle provided by the present invention is as follows: by rotating the threaded rod 8, the lithium battery can enter the placement cavity 12 set inside the two fixed frames 3. When the lithium battery enters the placement cavity 12, it will first contact the adjacent sides of the two limit plates 5. Since the edges of the adjacent sides of the two limit plates 5 are set to be arc-shaped, the two limit plates 5 are squeezed by the lithium battery, so that the two limit plates 5 will move in opposite directions. In this process, the spring 11 will be compressed until the lithium battery completely enters the position between the two limit plates 5. The pushing force of the spring 11 allows the two limit plates 5 to fit against the outer wall of the lithium battery, thereby achieving the effect of fixing the lithium battery. The lithium battery is protected by the setting of the placement cavity 12, making the overall testing process safer.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
