The entire single-segment robotic arm 38 is designed to automatically turn the handlebars of an electric vehicle. When the grinding plate 39 is in contact with the handlebars, the downward movement of the grinding plate 39 indirectly turns the throttle. The further down the handlebars, the greater the power. The lap speed detection end 9 at the bottom of the second side shell 3 continues to record. It should be noted that when the vehicle enters the entire detection cover 4, the recognition probe 11 will take a picture of it and send the image back to the processing terminal 10 to quickly locate the positions of the throttle and brake, facilitating subsequent braking and speed detection. The single-segment robotic arm 38 can be flipped.
[0026] Color difference detection end 5 is installed on the top of the inner side of the first side shell 2 and the second side shell 3, and concave and convex detection end 7 is installed on the bottom of the inner side of the first side shell 2 and the second side shell 3.

The output end of the drive motor 32 passes through the middle of the active gear 33 and drives the active gear 33 to rotate. Drive wheels 29 are installed on both sides of the front of the clamping controller 28. The drive wheels 29 on both sides mesh with the active gear 33. When the active gear 33 rotates clockwise, the drive wheels 29 on both sides will clamp inward. This clamping component is used to simulate the human hand squeezing the brake.

An adjusting ring opening 21 is provided on the top of the collar 20. A sloping plate 23 is snapped to the bottom of one side of the base plate 12. The collar 20 is fitted onto the handlebars of the electric vehicle, in a position close to the inside, to facilitate fixing the electric vehicle and ensure that the electric vehicle is upright. It should also be noted that during testing, the electric vehicle is supported by a tripod as usual when parking.
[0032] When inspecting a vehicle, the device first fastens the inclined plate 23 to the edge of the bottom 12 to facilitate pushing the vehicle. Before inspection, the vehicle is pushed onto the sliding plate 22. Then, the sliding plate 22 is moved to the inspection cover 4 by the lead screw structure controlled by the drive motor 24 for inspection. It should be noted that a bottom inspection instrument is installed in the bottom opening 27 at the top of the sliding plate 22 to detect whether there is any damage to the bottom of the vehicle. Specific Implementation Example 2:
[0034] Reference Figure 1-5 This multi-functional production line inspection device is used for automated quality inspection of electric vehicles, covering multi-dimensional inspection of the accelerator, brakes, vehicle body surface, and undercarriage. It features an IP65-rated protective shell, adapting to dusty and humid production line environments to ensure long-term stable operation. The device consists of an inspection cover 4 and a base plate 12, integrating various electronic components that work in coordination to achieve efficient inspection. After processing data, the processing terminal 10 transmits it to the next-level actuator via a specific interface. The next level actuator receives the instructions and executes the corresponding actions.
[0035] The specific testing process is as follows: First, the inclined plate 23 is snapped onto the edge of the base plate 12, facilitating the electric vehicle to be pushed in via the inclined plate 23 and placed on the sliding plate 22. The sliding plate 22 slides along the slide rail 26 at the top of the base plate 12, and its movement is controlled by the drive motor 24 via the drive shaft 25 (threaded connection). A moving block 14 is installed in the moving groove 13 on the sliding plate 22, driven by the moving block motor, and connected to the top of the upright rod 15. The upright rod 15 is movably connected to the lifting adjustment rod 16 through a hole. The top of the lifting adjustment rod 16 is threadedly connected to the insert 17. The adjusting wheel 18 on one side of the insert 17 is connected to the collar 20 via the connecting rod 19. The adjusting ring 21 of the collar 20 fits over the inner handlebar of the electric vehicle, adjusting the vehicle to be straight and fixed, maintaining the triangular support state. When the sliding plate 22 moves to the center of the testing cover 4, the bottom testing instrument installed in the bottom opening 27 at the top of the sliding plate 22 is activated, scanning the bottom of the vehicle to check for scratches, deformation, or missing parts. The data is transmitted to the processing terminal 10 via USB 3.0.
[0036] After the vehicle enters the inspection enclosure 4, the scanning probe 11 (high-definition industrial camera) inside the top shell 1 captures surface images and transmits them to the processing terminal 10 (embedded industrial computer) via USB 3.0. The processing terminal 10 runs an image recognition algorithm based on YOLOv5 to locate the throttle and brake positions and generate coordinate data. Subsequently, the inspection proceeds in the following order: First, the processing terminal 10 sends the throttle coordinates and movement commands to the lifting block motor via the RS485 interface, driving the lifting block 35 inside the first side shell 2 to move up and down along the side groove 34 to align with the throttle. The telescopic cylinder 36 on the lifting block 35 receives the extension command sent by the processing terminal 10 via RS485, pushing the single-segment robotic arm control end 37 to extend. The grinding plate 39 at the front end of the single-segment robotic arm 38 fits against the throttle handle, and the texture of the grinding plate 39 matches the throttle. The lifting block 35 continues to receive the downward movement command from the processing terminal 10, and the grinding plate 39 drives the throttle to rotate, simulating acceleration; the greater the amplitude, the greater the horsepower. The wheel speed detection terminal 9 (speed sensor) at the bottom of the second side shell 3 records the wheel speed and transmits it to the processing terminal 10 via the CAN bus to determine the throttle response time (which must be less than 0.5 seconds).
[0037] Next, the processing terminal 10 sends the braking coordinates and clamping commands to the gripping robotic arm control terminal 6 via the RS485 interface, driving the three-section robotic arm 8 in the middle of the second side shell 3 to move to the braking position. The gripping controller 28 at the end of the three-section robotic arm 8 receives the RS485 commands from the processing terminal 10 via the drive motor 32, driving the drive gear 33 to rotate clockwise, causing the drive wheel 29 to clamp inward. As the drive wheel 29 moves inward, the L-shaped side arms 30 on both sides also squeeze inward, clamping the brake handle through the clamping plates 31, simulating human hand compression. The clamping plates 31 have embedded clamping plate pressure sensors that detect the brake rebound force (50-150N required), and the data is transmitted to the processing terminal 10 via I2C. The lap speed detection terminal 9 synchronously records the speed change during braking and feeds it back to the processing terminal 10 via the CAN bus to verify the braking effect.
[0038] Simultaneously, the color difference detection end 5 (color difference sensor) on the top inner side of the first side shell 2 and the second side shell 3, and the bottom concavity / convexity detection end 7 (laser range sensor) synchronously scan the vehicle body to detect coating color consistency and surface concavities, protrusions, or scratches (accuracy 0.01 mm). The color difference detection end 5 transmits data to the processing terminal 10 via an I2C interface, and the concavity / convexity detection end 7 transmits data via an RS232 interface. The processing terminal 10 analyzes the throttle, brake, surface, and bottom status using a TensorFlow-based AI algorithm, and the results are displayed on a 15-inch touchscreen. If a non-conformity is detected (such as insufficient brake rebound force or surface defects), the processing terminal 10 triggers an audible and visual alarm (via a built-in buzzer and LED lights) and sends a command to the drive motor assembly 24 via an RS485 interface, driving the sliding plate 22 to move to the sorting area outside the detection cover 4. The detection data is uploaded to the production line management system via Wi-Fi 6 for subsequent traceability.
