The present invention solves the current problem of the lack of vehicle tire motion trajectory detection devices.

[0061] Example 2, based on Example 1, Figure 1-3 As shown, the front wheel trajectory detection device includes:

[0062] A radar detection module 2 is provided at the middle of the front end of the detection device body 1. The radar detection module 2 includes a laser radar 201 and a millimeter-wave radar 202. The laser radar 201 and the millimeter-wave radar 202 are fixedly connected to the front end of the detection device body 1.

[0068] A laser radar 201 may also be provided to detect the change in the relative position distance between the rear wheel 1 1003 and the rear wheel 2 1004 .

[0069] The working principle and beneficial effects of the above technical solution are as follows: the laser radar 201 detects the relative position distance changes between the front wheel 1001 and the front wheel 2 1002 and the road obstacles in front of the vehicle chassis; the measurement accuracy is accurate and it is detected together with the millimeter wave radar 202.

The scanned distance and obstacle data are transmitted to the on-board computer through the wireless transceiver 9. At the same time, the infrared detection camera 1 3 collects and records the image of the front wheel 2 1002, and the infrared detection camera 2 4 collects and records the image of the front wheel 1 1001; cross-collection of images avoids the occurrence of image acquisition blind spots.

[0071] Example 3, based on Example 1 or 2, Figure 2-5 As shown, the infrared detection camera 1 3 and the infrared detection camera 2 4 are both connected to the detection device body 1 through a first rotating mechanism, and the first rotating mechanism includes:

[0072] A first camera rotating housing 304, which is fixedly connected to the detection device body 1. A rotating motor 1 301 is provided in the first camera rotating housing 304, and a shaft end of the rotating motor 1 301 is fixedly connected to a gear 2 303;

[0074] The infrared detection camera 3 5 is connected to the left telescopic leg 507 through a second rotating mechanism, and the infrared detection camera 4 6 is connected to the right telescopic leg 601 through a second rotating mechanism. The second rotating mechanism includes:

[0075] A second camera rotating housing 508, which is fixedly connected to the left telescopic leg 507 or the right telescopic leg 601. A second rotating motor 501 is provided in the second camera rotating housing 508, and a shaft end of the second rotating motor 501 is fixedly connected to a fourth gear 503;

[0076] Gear three 502 is fixedly connected to the tail end of infrared detection camera three 5 or infrared detection camera four 6. Gear three 502 is rotationally connected to the second camera rotating shell 508, and the gear three 502 is engaged with gear four 503.

[0077] The working principle and beneficial effects of the above technical solution: the wireless transceiver 9 receives the adjustment value command from the on-board computer to control the operation of the servo motors on both sides, the servo motor drives the driving gear 505 to rotate, the driving gear 505 drives the linear rack 506 to move left and right, and the left telescopic leg 507 or the right telescopic leg 601 moves in the corresponding square tube 504 to adjust the position of the infrared detection camera three 5 or the infrared detection camera four 6.

[0078] The wireless transceiver 9 receives the adjustment value command from the on-board computer and controls the rotation motor 1 301 to operate. The rotation motor 1 301 drives the gear 2 303 to rotate. The gear 2 303 transmits the power to the gear 1 302, causing the gear 1 302 to rotate, thereby adjusting the angle of the infrared detection camera 3 5 or the infrared detection camera 4 6 on the gear 1 302 to align with the rear tire tread.

[0079] The wireless transceiver 9 receives the adjustment value command from the on-board computer and controls the operation of the rotating motor 2 501. The rotating motor 501 drives the gear 4 503 to rotate, and the gear 4 503 transmits the power to the gear 3 502, causing the gear 3 502 to rotate, thereby adjusting the angle of the infrared detection camera 3 5 or the infrared detection camera 4 6 on the gear 3 502 to align with the rear tire surface.

[0080] Example 4, based on any one of Examples 1-3, Figure 3 As shown, it also includes: a steering angle detection module, the steering angle detection module includes a laser sensor 1 801, a laser sensor 2 802, a laser sensor 3 803 and a laser sensor 4 804;

The laser sensor 1 801 is obliquely aimed at the inner side of the second front wheel 1002 of the car; the laser sensor 2 802 is obliquely aimed at the inner side of the first front wheel 1001 of the car;

The steering angle detection module is electrically connected to the microcontroller.

[0083] The working principle and beneficial effects of the above technical solution are as follows: Since most cars are rear-wheel driven and the front wheels are responsible for steering, the actual steering angle of the front wheels determines the direction of the movement trajectory of the car tires, and the movement trajectory of the rear wheels can be calculated based on the front wheel trajectory and the inner wheel difference and detection data; laser sensor 1 801 and laser sensor 2 802 detect the distance change between front wheel 1 1001 and front wheel 2 1002, and laser sensor 3 803 and laser sensor 4 804 are responsible for detecting and recording the angle numbers of front wheel 1 1001 and front wheel 2 1002; the data is transmitted to the on-board computer through the wireless transceiver 9, and the on-board computer calculates the steering angles of front wheel 1 1001 and front wheel 2 1002.

[0086] The beneficial effects of the above technical solution are as follows: the gyroscope 7 is responsible for detecting the inertial offset angle of the vehicle's motion trajectory, transmitting it to the on-board computer to calculate the centrifugal force of the tire drift state and the actual drift distance of the tire; the acceleration sensor 701 records the driving acceleration and transmits it to the on-board computer through the wireless transceiver 9; the GPS locator 702 obtains the blurred vehicle driving trajectory through satellite positioning, and the on-board computer restores the three-dimensional space tire motion trajectory image by comparing the blurred motion trajectory with the detected data, which is beneficial to improving the accuracy of the tire motion trajectory.

[0087] Example 6, based on Example 5, Figure 7 As shown, the installation box 703 is connected to a joint installation device, and the joint installation device includes:

[0088] A bilaterally symmetrical installation group, comprising:

[0089] Motor 704, motor 704 is connected to the outside of the installation box 703;

The GPS locator mounting hole 711 is located between the left and right clamping plates 709 at the bottom, and the acceleration sensor mounting hole 710 is located between the left and right clamping plates 709 at the top.

[0094] The working principle and beneficial effects of the above technical solution are as follows: when the GPS locator 702 and the acceleration sensor 701 are needed, the GPS locator 702 and the acceleration sensor 701 are installed to the GPS locator installation hole 711 and the acceleration sensor installation hole 710 respectively, and the motors 704 on both sides are controlled to rotate forward. The motors 704 drive the two-way threaded rods 705 on both sides to rotate, and the two-way threaded rods 705 drive the upper slider 706 and the lower slider 706 to slide toward the middle of the two-way threaded rods 705. The slider 706 drives the connected movable rod 708 to move, and the linkage rod 7082 also rotates with the movable rod 708 to push the movable block 7081 to move. The movable block 7081 squeezes the wedge block 707 to move toward the middle, so that the clamping plates 709 on the left and right sides are brought together, and the GPS locator 702 is moved to the middle. When the GPS locator 702 and the acceleration sensor 701 are fixed, the motor 704 stops rotating the linkage rod 7082 and cooperates with the slider 706 to complete the self-locking state; when the GPS locator 702 and the acceleration sensor 701 need to be removed, the motor 704 is controlled to reverse, and the upper and lower sliders 706 move in the opposite direction to release the self-locking state; at this time, the left and right clamping plates 709 are restored to their initial state under the action of the elastic potential energy of their respective elastic connectors 7091, and the GPS locator 702 and the acceleration sensor 701 can be taken out; the installation box 703 can meet the needs of fixing the GPS locator 702 and the acceleration sensor 701, and at the same time facilitate later replacement and maintenance or replacement of GPS locators 702 and acceleration sensors 701 of other sizes.
