[0003] Existing lithium battery testing equipment has a limited testing scope when testing the strength of lithium battery casings. It cannot perform impact tests on different locations on the casing surface according to the different sizes of lithium batteries, which directly affects the accuracy of the test results and reduces the overall precision of the equipment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a lithium battery testing device that solves the problem of an overly limited testing range, which makes it impossible to perform impact tests on different locations on the surface of the lithium battery casing according to its size.

[0005] This utility model is implemented as follows: a lithium battery testing device includes a placement rack for placing a lithium battery for testing, and two sets of electric push rods symmetrically embedded in the left-right direction. Each set of electric push rods has a pressure plate fixed on its piston rod for limiting the position of the lithium battery. The front of the placement rack is provided with an adjustable impact assembly for multi-point impact testing of the lithium battery.

[0006] As a preferred embodiment of this utility model, the adjustable impact assembly includes an electric slide rail fixed to the front of the placement frame, a docking frame fixed on the slide rail, a docking shaft rotatably mounted on the docking frame, a rotating plate fixed to one end of the docking shaft, a small cylinder embedded at one end of the rotating plate, an impact block for impacting the lithium battery casing on the piston rod of the small cylinder, a motor fixed to one side of the top of the front of the docking frame via a side frame, a Z-shaped crankshaft fixed to the output shaft of the motor, and a slot for inserting the Z-shaped crankshaft at the other end of the rotating plate.

[0019] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 3As shown in the figure, the lithium battery testing device provided by this utility model includes a placement rack 1 for placing a lithium battery for testing. A controller is provided at the bottom of one side of the placement rack 1. It also includes two sets of electric push rods 2 symmetrically embedded in the left-right direction. Each set of electric push rods 2 has a pressure plate fixed on its piston rod for limiting the position of the lithium battery. An adjustable impact component is provided on the front of the placement rack 1 for multi-point impact testing of the lithium battery. By setting the adjustable impact component and using the impact block 10 that can change position independently, the impact testing range of the lithium battery casing is expanded so that different positions on the surface of the casing can be impacted one by one according to the different sizes of the lithium battery, thereby improving the accuracy of the test results.

[0022] As a preferred embodiment of this utility model, the adjustable impact assembly includes an electric slide rail 4 fixed to the front of the placement frame 1. A docking frame 5 is fixed on the slide rail 4, and a docking shaft 6 is rotatably mounted on the docking frame 5. A rotating plate 7 is fixed to one end of the docking shaft 6, and a small cylinder 8 is embedded in one end of the rotating plate 7. The piston rod of the small cylinder 8 is provided with an impact block 10 for impacting the lithium battery casing. A motor 12 is fixed to one side of the top of the front of the docking frame 5 via a side frame. A Z-shaped crankshaft 13 is fixed to the output shaft of the motor 12. The other end of the plate 7 is provided with a strip groove 14 for inserting the Z-shaped crankshaft 13. The design of the electric slide rail 4, motor 12, Z-shaped crankshaft 13 and strip groove 14 allows the left-right and up-down positions of the impact block 10 to be freely changed, so as to expand the impact test range of the lithium battery casing. In addition, the overall length of the electric slide rail 4 is greater than the overall length of the placement frame 1, which further expands the impact range of the impact block 10 on the lithium battery casing, avoids the occurrence of impact dead angles, and further improves the overall test accuracy of the device.

[0023] As a preferred embodiment of this utility model, the piston rod of the small cylinder 8 is fixed with a connector 9, which has an external thread. The impact block 10 has an internal thread for the external thread to engage. The connector 9, in conjunction with the internal and external threads, allows the impact block 10 to be quickly disassembled and assembled, so that different specifications of impact blocks 10 can be quickly replaced according to the test requirements, which further improves the test accuracy and simultaneously improves the overall functionality of the device.

[0024] As a preferred embodiment of this utility model, a reinforcing frame 11 is fixed to the other end of the docking shaft 6. The end of the reinforcing frame 11 away from the docking shaft 6 is fixed to the rotating plate 7. The design of the reinforcing frame 11 can support and position the rotating plate 7, thereby improving the overall stability of the rotating plate 7.

[0025] As a preferred embodiment of this utility model, the electric slide rail slide 4 has a support frame fixed on its slide, and the top of the support frame is fixed on the docking frame 5. The design of the support frame improves the overall stability of the docking frame 5, effectively prevents the docking frame 5 from easily breaking and tilting backward, ensures the impact accuracy of the impact block 10, and further improves the test accuracy.

[0026] As a preferred embodiment of this utility model, both sides of the back of the electric slide rail 4 are fixed with inclined plates, and one end of the inclined plate is fixed on the placement frame 1. The design of the inclined plate can fix the electric slide rail 4, thereby improving the overall stability of the electric slide rail 4.

[0027] As a preferred embodiment of this utility model, a placement plate 3 is fixed at the bottom of the inner cavity of the placement rack 1. The placement plate 3 is used to raise the overall height of the lithium battery. The placement plate 3 can raise the overall height of the lithium battery so that the impact block 10 can better impact the bottom position of the lithium battery. This avoids the rotating plate 7 from impacting the placement rack 1 before the impact block 10 contacts the bottom of the front of the lithium battery, thus improving the stability of the device during operation and further improving the impact test accuracy of the impact block 10 on the lithium battery casing.

[0028] The working principle of this utility model:

[0029] refer to Figures 1 to 3 The user first places the lithium battery whose casing strength needs to be tested on the placement plate 3, ensuring its back is against the placement rack 1. Then, the user activates the electric push rod 2 via the controller, which drives the pressure plate to move and press down on both sides of the lithium battery. Next, the user activates the electric slide rail 4 and motor 12 according to the desired test position. The motor 12 then drives the Z-shaped crankshaft 13 to rotate, and with the cooperation of the strip groove 14, provides the Z-shaped crankshaft 13 with a certain amount of movement, thereby driving the rotating plate 7 to swing, thus adapting to the vertical position of the small cylinder 8 and the impact block 10. After adjustment, the electric slide rail 4, in cooperation with the docking frame 5, can drive the small cylinder 8 and the impact block 10 to make adaptive adjustments to their left and right positions until the impact block 10 is adjusted to a suitable position. At this time, the user can open the small cylinder 8 through the controller to drive the impact block 10 to impact the lithium battery casing, thereby testing the strength of the lithium battery casing. At this time, the impact block 10, which can change position independently, expands the impact test range of the lithium battery casing. Depending on the size of the lithium battery, different positions on its casing surface can be impacted one by one, improving the accuracy of the test results.
