[0016] In example two, referring to Figures 4-9 The present application is a kind of electric vehicle parts function inspection equipment and its inspection method, based on example one, alarm detection device 5 includes hydraulic cylinder 501, the inner wall of hydraulic cylinder 501 is slidably connected with push rod 502, the outer surface of hydraulic cylinder 501 is fixedly connected with back spring 503, the back spring 503 is fixedly connected with hollow round block 504 away from hydraulic cylinder 501, the outer surface of hollow round block 504 is rotatably connected with buckle plate 505, the surface of buckle plate 505 away from hollow round block 504 is fixedly connected with thorn cone 506, the inner wall of hollow round block 504 is slidably connected with pressure sensing block 507, the outer surface of pressure sensing block 507 is slidably connected with center block 508, the outer surface of center block 508 is fixedly connected with top punch spring 509, the inner wall of top punch spring 509 is fixedly connected with top punch plate 510, hydraulic cylinder 501 drives push rod 502, so that hollow round block 504 moves to the inside of car lock shell 2, so that pressure sensing block 507 in the inside of hollow round block 504 is pressed against the inside part, pressure sensing block 507 is pressed to move to the inside of hollow round block 504, pushes and pushes top punch plate 510 upwards, so that buckle plate 505 rotates upwards, drives thorn cone 506 to contact the inside part, until pressure sensing block 507 touches push rod 502, so that hydraulic cylinder 501 removes the pushing force, at the same time, back spring 503 drives hollow round block 504 to retract quickly, so that thorn cone 506 produces scratches on the surface of the part.

[0017] The tension detection device 4 includes a threaded handle 401. A threaded block 402 is threadedly connected to the outer surface of the threaded handle 401. An inner pressure arc plate 403 is slidably connected to the side of the threaded block 402 away from the threaded handle 401. An inner pressure spring 404 is fixedly connected to the inner wall of the inner pressure arc plate 403. A magnetic suction hole 405 is opened at one end of the inner pressure arc plate 403 near the threaded handle 401. A magnetic snap-on 406 is fixedly connected to the other end of the inner pressure arc plate 403 near the threaded handle 401. There are two inner pressure arc plates 403, and the two inner pressure arc plates 403 are symmetrically arranged with the threaded handle 401 as the center. Rotating the threaded handle... Hand 401 pushes the threaded block 402 to the position of the part to be tested. The part abuts against the inner pressure arc plate 403 and enters the inner pressure area between the two upper and lower mating inner pressure arc plates 403. The inner pressure spring 404 applies internal pressure to the inner pressure arc plate 403, so that the inner pressure arc plate 403 is fastened to the part and the inner pressure arc plates 403 on both sides are in contact. The motor 6 is turned on and the tightness detection device 4 rotates at high speed. If the parts are loose, the inner pressure arc plates 403 on both sides will separate under the action of centrifugal force, thus detecting the looseness of the parts. After the rotation stops, the inner pressure arc plates 403 on both sides slowly magnetically clamp together.

[0018] The impact detection device 3 includes a disc 301 with a threaded hole 302 on its outer surface. A receiving post 303 is fixedly connected to the side of the disc 301 near the lock housing 2. A pendulum 304 is rotatably connected to the outer surface of the receiving post 303. An abutment spring 305 is fixedly connected to the inner wall of the disc 301. An abutment block 306 is fixedly connected to the bottom of the abutment spring 305. A tension spring 307 is in contact with the bottom of the abutment block 306. A retaining plate 308 is fixedly connected to the end of the tension spring 307 away from the disc 301. There are four pendulums 304, and the four pendulums 304 are symmetrically arranged with the lock housing 2 as the center. The motor... 6 drives the disc 301 to rotate at high speed toward the pendulum 304 and the clamping plate 308. The clamping plate 308 holds the pendulum 304 in place to prevent it from swinging and impacting the lock housing 2. When the disc 301 rotates to the driving speed, the abutment spring 305 contracts outward through centrifugal force, thereby causing the abutment block 306 to disengage from the clamping plate 308. This causes the tension spring 307 to retract the clamping plate 308, allowing the pendulum 304 to disengage from the clamping plate 308 and impact the lock housing 2. This simulates the impact of a wheel hitting a heavy object at high speed, thus testing the impact resistance of the lock housing 2 for easy replacement and optimization.

[0019] The method for testing the functionality of electric vehicle components includes the following steps: S1: Place the car lock, put the wheel lock components inside the housing detection device 1, and fit them against the inner wall of the transparent glass 106; S2: Shell integrity test. Colored gas is injected into the car lock shell 2 through the shell detection device 1, and the car lock shell 2 is observed to see if there is any damage through the transparent glass 106. S3: Alarm function test. The internal parts of the wheel lock are lightly polished by the alarm detection device 5 to test whether the alarm function is normal. S4: Part tightness detection, the tightness of the connection of the internal parts of the wheel lock is detected by the tightness detection device 4; S5: Impact strength detection. The wheel lock is impacted by a pendulum 304 using the impact detection device 3 to test the impact resistance of the wheel lock.

[0020] A specific application of this embodiment is as follows: When using this invention, the car lock housing 2 is placed inside the transparent glass 106, the air pump 101 is started, and colored gas is injected into the annular tube 103. The annular tube 103 diffuses the colored gas into the car lock housing 2 through the diffusion hole 104 until the colored gas fills the car lock housing 2. The condition inside the internal cavity 107 is observed. If the housing is damaged or has a hole, the colored gas will diffuse into the internal cavity 107. If the housing is intact, there is no colored gas in the internal cavity 107. After the colored gas fills the internal cavity 107, it enters the return pipe 105 and is recycled and reused through the return pipe 105. Hydraulic cylinder 501 pushes push rod 502, causing hollow block 504 to move into the car lock housing 2. This causes pressure sensor block 507 inside hollow block 504 to press against internal parts. Pressure sensor block 507 is pressed into hollow block 504, pushing the top punch plate 510 upward, causing fastening plate 505 to rotate upward, driving spike 506 to contact internal parts until pressure sensor block 507 touches push rod 502. This causes hydraulic cylinder 501 to release the thrust, and at the same time, return spring 503 drives hollow block 504 to retract quickly, causing spike 506 to scratch the surface of the parts. Rotate the threaded handle 401 to push the threaded block 402 to the position of the part to be tested. The part abuts against the inner pressure arc plate 403 and enters the inner pressure area between the two upper and lower mating inner pressure arc plates 403. The inner pressure spring 404 applies internal pressure to the inner pressure arc plate 403, so that the inner pressure arc plate 403 is fastened to the part and the inner pressure arc plates 403 on both sides are in contact. Turn on the motor 6 and the tightness detection device 4 rotates at high speed. If the parts are loose, the inner pressure arc plates 403 on both sides will separate from each other under the action of centrifugal force, thereby detecting the looseness of the parts. After the rotation stops, the inner pressure arc plates 403 on both sides slowly magnetically clamp together. The electric motor 6 drives the disc 301 to rotate at high speed towards the pendulum 304 and the clamping plate 308. The clamping plate 308 holds the pendulum 304 in place to prevent it from swinging and impacting the lock housing 2. When the speed of the disc 301 increases to the driving speed, the abutment spring 305 contracts outward through centrifugal force, thereby causing the abutment block 306 to disengage from the clamping plate 308. This causes the tension spring 307 to retract the clamping plate 308, allowing the pendulum 304 to disengage from the clamping plate 308 and impact the lock housing 2. This simulates the impact of a wheel hitting a heavy object at high speed, thus testing the impact resistance of the lock housing 2 for easy replacement and optimization.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
