Technical Field

[0001] This utility model relates to the field of motor vehicle inspection technology, and in particular to a motor vehicle wheel track measuring device based on a laser rangefinder. Background Technology

[0002] The wheel track is the distance between the center lines of the wheels on both sides of a motor vehicle. It has a significant impact on the vehicle's handling, stability, safety, and tire wear. By measuring the wheel track, potential vehicle problems can be detected in time, providing a basis for vehicle maintenance and troubleshooting, ensuring that the vehicle is always in a safe and reliable operating condition, extending the vehicle's service life, and improving road traffic safety.

[0003] Chinese Patent Publication No. CN216694773U discloses a vehicle wheel track measuring device, relating to the field of vehicle-related technology.

A first screw is rotatably connected to the measuring platform inside the first hollow groove, and a second screw is rotatably connected to the measuring platform inside the second hollow groove. A second measuring block is disposed inside the measuring platform in the first hollow groove. This invention improves upon the problem that existing methods of measuring wheel track often rely on rulers or measuring tapes, which are cumbersome. In this invention, the measuring rod further limits the movement of the second and first measuring blocks. Simultaneously, the measuring rod displays the distance between the first and second measuring blocks through a graduated groove on its outer side, facilitating observation and recording of wheel track values ​​by the operator.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-5 A vehicle wheelbase measuring device based on a laser rangefinder includes a ranging housing 1. Two support rods 2 are symmetrically distributed and movably installed inside the ranging housing 1. A ranging component 3 is respectively installed on the top of the end of each support rod 2 away from the ranging housing 1. The ranging component 3 includes an L-shaped support block 301, a sliding groove 302, a push rod 303, a moving block 304, a mounting block 305, a laser rangefinder 306, a pointer 307, and a scale bar 308. The L-shaped support block 301 is fixedly installed on... The top of the two support rods 2, the movable slide 302 is opened on the top of the L-shaped support block 301, the push rod 303 is fixedly installed inside the movable slide 302, the movable block 304 is fixedly installed on the push end of the push rod 303, the mounting block 305 is fixedly installed on the top of the movable block 304, the laser rangefinder 306 is fixedly installed on the side of the mounting block 305, the pointer 307 is fixedly connected to the front end of the mounting block 305, and the scale bar 308 is fixedly installed on the top of the L-shaped support block 301;

[0026] The laser rangefinder 306 includes a laser emitter 3061 and a laser receiver 3062. The laser emitter 3061 is fixedly installed on the right side of the left mounting block 305, and the laser receiver 3062 is fixedly installed on the left side of the right mounting block 305.

[0027] The pointer 307 is compatible with the scale bar 308, and the laser emitter 3061 and laser receiver 3062 are compatible. The laser rangefinder 306 is existing technology. With the ranging component 3 in place, after the L-shaped support block 301 is attached to the opposite side between the front wheels of the vehicle, the push rod 303 is activated. This causes the push end of the push rod 303 to move the moving block 304 and the mounting block 305. During this movement, based on the indication of the pointer 307 on the upper part of the scale bar 308, the mounting block 305 is moved to the middle position of the front wheels of the vehicle. Then, the laser rangefinder 306 is activated to measure the distance between the front wheels of the vehicle. This invention, through the setting of the ranging component 3, not only allows for accurate and rapid location of the middle of the vehicle wheels using the pointer 307 and scale bar 308, but also effectively improves the measurement speed and accuracy using the laser rangefinder 306, thereby significantly increasing the work speed of the operator and facilitating its use.

[0028] Furthermore, a moving component is provided inside the ranging box 1 and outside the support rod 2. The moving component includes a telescopic slide 201, a limiting slide 202, a bidirectional motor 203, a lead screw 204, a limiting slide bar 205, and a threaded hole 206. The telescopic slide 201 is opened at the front end of the ranging box 1, and the limiting slide 202 is opened on the inner wall of the telescopic slide 201.

[0029] The bidirectional motor 203 is fixedly installed inside the telescopic slide 201, the lead screw 204 is fixedly connected to the transmission ends on the left and right sides of the bidirectional motor 203, the limiting slide bar 205 is fixedly connected to the rear end of the support rod 2, and the threaded hole 206 is opened inside the support rod 2.

[0030] The movable component is designed so that activating the bidirectional motor 203 causes the lead screws 204 on both sides to rotate. During rotation, due to the fit between the limiting slide bar 205 and the telescopic slide groove 201, and the threaded connection between the lead screw 204 and the support rod 2, the two support rods 2 can be extended outward. This invention, through the movable component, allows the L-shaped support block 301 to be supported between the front wheels of a vehicle via the support rods 2, effectively preventing the device from shaking during measurement and improving the accuracy of the final measurement data.

[0031] Furthermore, a control panel 4 is fixedly installed at the rear end of the ranging housing 1, and a display screen 5 is fixedly installed at the rear end of the ranging housing 1 and above the control panel 4. The control panel 4 is electrically connected to the display screen 5 and the laser rangefinder 306 respectively.

[0032] The bottom of the ranging box 1 is fixedly connected to an anti-slip pad 6, and the top of the ranging box 1 is fixedly connected to an auxiliary block 7. A handle 8 is rotatably connected to the outside of the auxiliary block 7.

[0033] The installation of the display screen 5 allows the data measured by the laser rangefinder 306 to be displayed, making it convenient for staff to record the data and improving the ease of measurement. The installation of the handle 8 makes it easy for staff to carry the device, effectively improving its portability.

[0034] Furthermore, the lead screw 204 is threadedly connected to the support rod 2 through the threaded hole 206, and the limiting slide 205 is adapted to the telescopic slide 201.

[0035] In summary:

[0036] In use, the device is first placed at the bottom of a motor vehicle between the front wheels. Then, the bidirectional motor 203 is started, which drives the lead screws 204 on both sides to rotate. During the rotation, due to the fit between the limiting slide bar 205 and the telescopic slide groove 201, and the threaded connection between the lead screw 204 and the support rod 2, the two support rods 2 can be driven to extend outward.

[0037] During the extension of the two support rods 2, the L-shaped support block 301 can be driven to lock onto the side of the front wheel. Then the push rod 303 can be activated, so that the push end of the push rod 303 pushes the moving block 304 and the mounting block 305 to move. During the movement, according to the indication of the pointer 307 on the upper part of the scale bar 308, the mounting block 305 is moved to the position of the middle of the front wheel of the motor vehicle.

[0038] Finally, activating the laser rangefinder 306 will allow the distance between the front wheels of the vehicle to be measured and displayed on the screen 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
