Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment technology, specifically a chassis scanner for automotive testing. Background Technology

[0002] The booming development of the automotive industry has placed higher demands on vehicle safety and performance testing. As a key component of a vehicle, the chassis's condition directly affects driving safety. Therefore, efficient and accurate chassis inspection technology is crucial. Traditional chassis inspection methods often rely on manual visual inspection using flashlights or pits, which is not only inefficient and poses safety hazards but also fails to meet the needs of modern automotive inspection.

[0003] Chassis scanners, as a modern inspection device, are designed to achieve rapid, comprehensive, and non-contact image acquisition and inspection of automotive chassis. However, some existing chassis scanning devices still have limitations in practical applications. For example, when adapting to vehicles with different wheelbases and track widths, the adjustment of their positioning and scanning mechanisms is often not convenient or precise enough, affecting inspection efficiency. The synchronous movement accuracy and stability of the scanning device are crucial to image quality, but the drive and positioning system designs of some devices are not optimized enough, which may lead to scanning trajectory deviations or difficulties in image stitching, ultimately affecting the accuracy and reliability of the inspection results. Utility Model Content

[0004] The purpose of this invention is to provide a chassis scanner for vehicle inspection, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chassis scanner for vehicle inspection, comprising a base plate and wheel positioning plates. Two first slide rails are symmetrically mounted on both sides of the base plate. Two first sliders are slidably connected to each of the two first slide rails on their respective upper sides. A second slide rail is welded between the two first sliders on the same side of the two first slide rails. A bidirectional moving assembly is installed between the two second slide rails and the first slide rails. Four positioning plate mounting posts are mounted above the four first sliders. Two wheel positioning plates are welded to the positioning plate mounting posts. A lifting assembly is installed between the wheel positioning plates and the base plate. Two servo motor mounting posts are mounted diagonally on the upper surface of the base plate. Two servo motors are mounted on the two servo motor mounting posts. Two synchronous pulleys are mounted on the output shafts of the two servo motors. A synchronous pulley mounting post is mounted at one corner of the upper part of the base plate. Two synchronous pulleys are mounted above the adjacent side of the synchronous pulley mounting post. The servo motors and the synchronous pulleys on the pulley mounting posts are connected to corresponding synchronous belts.

[0006] Preferably, the bidirectional moving assembly includes two threaded screw mounting blocks mounted on two first slide rails. A bidirectional threaded screw is mounted between the two threaded screw mounting blocks via a bearing. A handwheel is mounted on one side of the bidirectional threaded screw through a threaded screw mounting block. Two threaded tubes are threadedly connected to the two threads of the bidirectional threaded screw. Two first and second support rods are symmetrically mounted on the sidewalls of the two threaded tubes via a rotating shaft. The first and second support rods are connected in an "X" shape via a rotating shaft. The other ends of the first and second support rods are connected to a second slider via a rotating shaft. The second slider is slidably connected to the second slide rail. This improves adjustment efficiency.

[0007] Preferably, the lifting assembly includes a groove on the upper surface of a wheel positioning plate, within which two wheel support plates are symmetrically mounted via a rotating shaft. A pulley is mounted on the lower surface of each wheel support plate via the rotating shaft. A top wheel plate is positioned below the pulley. Top wheel side plates are mounted on both sides of the top wheel plate. A top wheel base plate is installed between the lower side walls of the two top wheel side plates. Two top wheel plate support columns are mounted below the top wheel base plate. The bottom surfaces of the top wheel plate support columns are welded to the upper surface of the base plate. A motor is mounted on the side of each top wheel plate support column. A threaded rod is mounted on the motor via a coupling. The threaded rod passes through the top wheel base plate via a threaded connection. The upper surface of the threaded rod is connected to the top plate support plate via a bearing. The upper surface of the top plate support plate contacts the lower surface of the top wheel plate. This design secures the wheel.

[0008] Preferably, the wheel positioning plate has a ramp installed on its side wall, and the top edge of the ramp is at the same height as the upper surface of the wheel positioning plate. Vehicles can smoothly drive into the inspection station without additional power assistance.

[0009] Preferably, a first positioning plate and a second positioning plate are mounted on the upper surfaces of the two synchronous belts. A positioning slider is slidably connected at the intersection of the first and second positioning plates. A rolling support assembly is installed between the first positioning plate and the base plate. This enables precise path movement of the camera in the chassis area.

[0010] Preferably, the rolling support assembly includes two roller plate support columns mounted on one side of the upper surface of the base plate, with roller plates mounted on the roller plate support columns. A roller is mounted in a groove at one end of the first positioning plate via a rotating shaft, and the roller contacts the upper surface of the roller plate. This maintains stable movement of the first and second positioning plates.

[0011] Preferably, the first positioning plate and the second positioning plate are perpendicular to each other, and a camera is installed on the positioning slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Wheelbase adaptive adjustment: The bidirectional moving component drives a bidirectional threaded screw via a handwheel, which in turn drives the X-shaped support mechanism to synchronously open and close the second slide rail. This structure allows the spacing between the wheel positioning plates on both sides to accurately match vehicles with different wheelbases, without the need to replace parts or perform complex calibrations, significantly improving the versatility and positioning efficiency of the testing equipment.

[0014] Wheel gravity self-locking: The motor driving the threaded rod of the lifting assembly raises and lowers the top wheel plate, which is then converted into a positional change of the wheel support plate via a pulley mechanism, thereby locking the wheel. This design fixes the wheel and prevents the vehicle from moving, ensuring that the scanning equipment is always in the optimal detection position and significantly improving detection accuracy.

[0015] Synchronous positioning of the scanning mechanism: Dual servo motors drive the first and second positioning plates via synchronous belts, which, together with the roller support assembly, enable smooth movement of the scanning platform. The camera on the positioning slider can slide freely along the intersecting tracks and rotate freely, forming a scanning path covering the entire chassis area, completely eliminating detection dead zones.

[0033] Working principle:

[0034] Vehicle positioning and wheel track adjustment: When the vehicle enters the testing area, the front wheels are guided along the ramp 1 to the wheel positioning plates 3 on both sides. The operator turns the handwheel 10, driving the bidirectional threaded screw 21 to rotate. The two reverse threads of the screw drive the two threaded tubes 22 to move in opposite directions, thereby pushing the X-shaped linkage mechanism composed of the first support rod 23 and the second support rod 24 to unfold or retract. The second slider 25 at the end of the linkage slides along the second slide rail 6, synchronously driving the two second slide rails 6. The two second slide rails 6 drive the first sliders 5 at both ends to slide on the first slide rail 4. The first sliders 4 drive the positioning plate support column 7 and the wheel positioning plates 3 on it to move until the spacing of the wheel positioning plates 3 matches the vehicle's wheel track, completing the lateral positioning of the wheels.

[0035] Vehicle body fixing: The vehicle is driven onto the wheel positioning plate 3, with the front wheels positioned between the two wheel support plates 3. The motor 13 is started, driving the threaded rod 18 to rotate. The threaded rod 18, through its threaded engagement with the top wheel base plate 36, pushes the top plate support plate 28 to rise and fall vertically. The top plate support plate 28 causes the top wheel plate 20 to move downward, and the top wheel plate 20, in turn, causes the pulley 27 to move downward, resulting in a depression formed on both sides of the two wheel support plates 3. The wheels are then engaged in the depression, thus fixing the vehicle body.

[0036] The chassis scanning system executes as follows: Two servo motors 12 start synchronously, driving the entire transmission system via synchronous pulleys 14 on the output shaft, synchronous pulley mounting posts 15, and synchronous belts 16. Synchronous belt 16 drives the first positioning plate 29 and the second positioning plate 30. Rollers 35 at the end of the first positioning plate 29 roll on roller plates 33, ensuring smooth movement. Through linkage with the positioning slider 31, the camera 32 mounted on it moves precisely in the X and Y directions in the horizontal plane. The camera 32's rotatable angle enables a grid-like coverage scan of the chassis area. After scanning, motor 13 reverses and raises the wheel support plate 26, allowing the vehicle to drive away.
