Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection equipment technology, specifically a stretchable five-camera four-wheel alignment instrument. Background Technology

[0002] Four-wheel alignment is a key technology in automotive repair and inspection, directly affecting vehicle safety, stability, and tire wear. Traditional four-wheel alignment machines often use laser or infrared sensors for measurement, and their accuracy is significantly affected by factors such as ambient light and mechanical wear. In recent years, with the development of computer vision technology, camera-based vision positioning systems have gradually been introduced into the field of four-wheel alignment. By using multiple cameras to collaboratively capture images of the wheels and targets, combined with image processing and calibration algorithms, high-precision, non-contact measurement of wheel alignment parameters can be achieved. These systems typically include multiple camera units, arranged on both sides of the vehicle, which calculate parameters such as camber and toe angles by photographing targets mounted on the wheels.

[0003] However, existing visual four-wheel alignment systems still have some shortcomings in practical use. The camera unit is usually fixed on the bracket and cannot be flexibly adjusted according to the vehicle width, resulting in poor adaptability when facing different wheelbases or modified vehicles. When measuring widened vehicles or special models, the camera position cannot be adjusted accordingly, which may lead to poor shooting angle and difficulty in target identification, affecting measurement accuracy and the applicability of the system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a stretchable five-camera four-wheel alignment device to solve the problem of poor vehicle adaptability caused by the fixed position of the camera units, which cannot be adjusted according to the vehicle width, as mentioned in the background technology.

The second base shell 20 in both the first camera unit 1 and the second camera unit 2 has a sliding groove structure 21 inside. The pull-out mechanism 3 includes a first support plate 23. A second support plate 25 is fixedly installed on the top of the first support plate 23. A slide rail 26 is fixedly installed on the top of the second support plate 25. The sliding groove structure 21 inside the second base shell 20 is slidably disposed on the outer surface of the slide rail 26. Multiple indexing holes 29 are opened on the upper surface of the slide rail 26. Positioning holes 31 are opened inside the second base shell 20 in both the first camera unit 1 and the second camera unit 2. Quick-release pins 30 are provided inside the indexing holes 29 and the positioning holes 31.

[0017] Specifically, the first PCB board 6, the second PCB board 7, and the battery 8 are fixedly mounted on the upper surface of the base plate 5 in both the first camera unit 1 and the second camera unit 2. The top of the bottom shell 4 in both the first camera unit 1 and the second camera unit 2 is provided with a power switch 9 and a display screen 10. A charging module 32 is provided on the outside of the battery 8. The first PCB board 6 and the second PCB board 7 are used to process the image signals acquired by the camera and perform calculations. The battery 8 provides power to the entire system. The power switch 9 controls the on / off state of the circuit. The display screen 10 is used to display the positioning parameters and system status in real time. The charging module 32 provides a rechargeable interface for the battery 8.

[0018] Specifically, a first lampshade 17, a second lampshade 18, and a third lampshade 19 are fixedly installed on the front and left and right sides of the bottom shell 4 in the first camera unit 1 and the second camera unit 2, respectively. The first lampshade 17 in the first camera unit 1 is located outside the first camera group 11, the second lampshade 18 in the first camera unit 1 is located outside the second camera group 12, and the third lampshade 19 in the first camera unit 1 is located outside the third camera group 13. The function of the first lampshade 17, the second lampshade 18, and the third lampshade 19 is to provide protection for the corresponding camera group, prevent dust and bumps from damaging the lens, and at the same time, their light-transmitting design can ensure that light passes through normally during shooting.

[0019] Specifically, the first lampshade 17 in the second camera unit 2 is located outside the target group 14, the second lampshade 18 in the second camera unit 2 is located outside the fourth camera group 15, and the third lampshade 19 in the second camera unit 2 is located outside the fifth camera group 16.

[0020] Specifically, the contact surface between the slide structure 21 and the slide rail 26 is provided with a silicone damping pad 22, and the outer surface of the first bracket plate 23 is provided with multiple mounting holes 24. The function of the silicone damping pad 22 is to provide a smooth damping feel during sliding adjustment, prevent the camera unit from sliding accidentally, and reduce vibration and noise.

[0021] Specifically, a pin 27 is provided at the connection between the second support plate 25 and the slide rail 26. A nut 28 is threaded onto the outer surface of the pin 27. The second support plate 25 and the slide rail 26 are connected by the pin 27 and the nut 28. The indexing holes 29 are linearly arranged along the upper surface of the slide rail 26. The cooperation between the pin 27 and the nut 28 realizes the detachable and fastened connection between the slide rail 26 and the second support plate 25, which is convenient for assembly and maintenance. The linearly arranged indexing holes 29 cooperate with the quick-release pins 30, providing a structural basis for realizing multi-position precise locking of the camera unit at different positions.

[0022] The working principle of the above embodiments: The positioning device mainly includes a first camera unit 1 and a second camera unit 2. Each camera unit has a pull-out mechanism 3 at its bottom. The distance between the two camera units and the vehicle body is adjusted through the sliding cooperation between the slide groove structure 21 and the slide rail 26. In use, the first camera unit 1 and the second camera unit 2 are fixedly installed on both sides of the vehicle through the first bracket plate 23. The distance is adjusted according to the actual needs of the vehicle. The adjustment method is to push and pull the bottom shell 20 to make it slide along the slide rail 26. When the first camera unit 1 or the second camera unit 2 is adjusted to a suitable position, the corresponding indexing hole 29 on the slide rail 26 is aligned with the positioning hole 31 on the bottom shell 20. The quick-release pin 30 is then inserted into the indexing hole. Hole 29 and positioning hole 31 are used for fixing. The silicone damping pad 22 set on the contact surface between the sliding groove structure 21 and the sliding rail 26 can ensure smooth sliding and have a certain resistance to avoid accidental displacement. After adjustment, the first camera unit 1 and the second camera unit 2 are responsible for acquiring images. All image data acquired by the cameras are processed by the first PCB board 6 and the second PCB board 7, and the positioning parameters are displayed in real time by the screen display 10. The battery 8 powers the entire system, and the charging module 32 supports repeated charging. The stepless adjustment of the camera distance is achieved through the pull-out structure, so that the positioning device can be adapted to both regular small vehicles and widened modified vehicles, thus expanding the applicability and measurement flexibility of the equipment.
