[0040] The movement of the vibration assembly 2 and the positioning assembly 3 is limited by the guide groove 12, so that the vibration assembly 2 and the positioning assembly 3 remain stable as a whole when moving.

[0041] Further, the vibration assembly 2 comprises a connecting plate 21 connected with the supporting column 11, and the two sides of the connecting plate 21 are slidably installed with a sliding plate 22, and the upper end of the sliding plate 22 is provided with a vibrating plate 23.

[0042] In the embodiment, the outer surface of the end of the connecting plate 21 is slidably connected with the inner wall of the guide groove 12, and the two sides of the connecting plate 21 are provided with vibration grooves, and the inner wall of the vibration groove is slidably connected with the outer surface of the sliding plate 22, so that the vibrating plate 23 is not interfered when moving up and down.

[0043] Further, one side of the connecting plate 21 is provided with a supporting plate 24, the lower end of the supporting plate 24 is provided with a driving piece 25, the output end of the driving piece 25 is provided with a rotating block 26, and the end of the rotating block 26 and away from the driving piece 25 is slidably installed with a movable rod 27.

When the driving piece 25 is started, the rotating block 26 provided at the output end of the driving piece 25 is driven to rotate, and in turn drives the movable rod 27 slidably installed on the rotating block 26 to rotate around the output end of the driving piece 25. The movable rod 27 can slide up and down at the end of the rotating block 26.

[0045] Further, the end of the supporting plate 24 is symmetrically provided with a fixed block 28, and the inner wall of the fixed block 28 is rotatably installed with a rotating shaft 29.

[0046] Specifically, when the rotating block 26 rotates, the limiting rod 293 is driven to shake in cooperation with the movable rod 27. Since the outer surface of the limiting rod 293 is connected with the rotating shaft 29 through the driving plate 292, and the outer surface of the rotating shaft 29 is limited by the fixed block 28, the vibrating block 291 fixedly arranged at the end of the rotating shaft 29 is shaken, so as to press the vibrating plate 23 and make the vibrating plate 23 move up and down, thereby jolt testing the battery box and detecting the sealing state inside the battery box.

[0047] Further, the positioning assembly 3 comprises a movable plate 31 connected with the supporting column 11, the upper end of the movable plate 31 is symmetrically provided with a positioning plate 32, and the end of the positioning plate 32 is provided with a through hole 33, and the inner wall of the through hole 33 is slidably installed with an adjusting rod 34.

[0048] In this embodiment, the adjusting rod 34 is limited by the through hole 33, and the outer surface of the end of the movable plate 31 is slidably connected with the inner wall of the guide groove 12, thereby adjusting the height of the battery box to adapt to different scenes.

[0049] Further, the outer surface of the adjusting rod 34 is provided with a clamping block 35, and the outer surface of the adjusting rod 34 and located at one side of the clamping block 35 is provided with a push rod 36, the outer surface of the push rod 36 is rotatably installed with a pressing rod 37, and the end of the pressing rod 37 is provided with a butt joint block 38, and the battery box is fixed by the butt joint block 38.

[0051] Further, a limiting groove 351 is formed on one side of the clamping block 35, a rotating rod 352 is slidably installed on the inner wall of the limiting groove 351, and the end of the rotating rod 352 is connected with the inner wall of the positioning plate 32. A protection groove 361 is formed on the outer surface of the push rod 36, and a protection rod 362 is slidably installed on the inner wall of the protection groove 361, and the end of the protection rod 362 is connected with the inner wall of the positioning plate 32.

[0052] Specifically, the limiting groove 351 on the clamping block 35 limits the rotating rod 352, so that when the adjusting rod 34 moves, the clamping block 35 is driven to rotate.

[0053] Meanwhile, the protection groove 361 on the push rod 36 limits the protection rod 362, so that when the push rod 36 rotates, the protection groove 361 protects the push rod 36, avoiding the push rod 36 from falling off when moving.

[0054] Further, the elastic member 39 is arranged at the middle position of the end of the movable plate 31, and the end of the elastic member 39 is connected with the lower end of the butt joint block 38.

[0055] Specifically, the elastic member 39 is a spring or other elastic component, which limits the butt joint block 38, so that when the butt joint block 38 moves away from the battery box, the elastic member 39 pushes the butt joint block 38 to the initial position, facilitating subsequent detection.

[0056] Further, the impact assembly 4 is assembled at the upper end of the operation table 1, and the impact assembly 4 simulates the collision of the battery box. The impact assembly 4 comprises a bottom plate 41 connected with the operation table 1, and the upper end of the bottom plate 41 is provided with a supporting rod 42. One side of the supporting rod 42 is provided with a power member 43, and the output end of the power member 43 is provided with a screw rod 44.

[0057] In this embodiment, the power member 43 is a motor or other device with power output, and is connected with an external control device. When the power member 43 is started, the screw rod 44 arranged at the output end thereof is synchronously driven to rotate, and the supporting rod 42 supports the power member 43 and the screw rod 44, so that they are in a stable state during operation.

[0058] At the same time, a movable groove 13 is opened at the upper end of the operating table 1, and the inner wall of the movable groove 13 is provided with a device with a telescopic function such as an electric telescopic rod, so that the entire impact assembly 4 can be driven by the electric telescopic rod to adjust its position, making it suitable for different scenarios.

[0059] Furthermore, a transmission block 45 is provided at the upper end of the bottom plate 41 and between the two support rods 42 , and the outer surface of the transmission block 45 is in contact with the outer surface of the spiral rod 44 .

[0060] Specifically, a plurality of groups of protrusions are evenly arranged on the outer surface of the transmission block 45 , and when the screw rod 44 rotates, the transmission block 45 is driven to rotate.

[0061] Furthermore, a sleeve 46 is provided at the upper end of the base plate 41, located on one side of the transmission block 45. The end of the transmission block 45 extends through and into the inner cavity of the sleeve 46. A crankshaft 47 is provided at the end of the transmission block 45, and multiple sets of pressing rods 48 are provided on the outer surface of the crankshaft 47. The outer surface of the sleeve 46 is provided with slots 461 corresponding to the pressing rods 48. The inner wall of the slot 461 is slidably connected to the outer surface of the pressing rods 48.

[0062] Specifically, when the transmission block 45 rotates, it synchronously drives the crankshaft 47 set at its end to perform a collision test. Since a plurality of pressing rods 48 are set on the outer surface of the crankshaft 47, when the crankshaft 47 rotates, the pressing rods 48 are driven to move up and down, thereby performing a collision test on the lower end of the battery box, thereby more accurately detecting the battery box.

[0063] The control device can be a single-chip microcomputer (MCU) as the control terminal. In this embodiment, the MCU is a typical embedded microcontroller (MCU), consisting of an arithmetic unit (ALU), a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low power consumption.
