[0002] As the vehicle is used, the tires will gradually wear out due to various factors such as friction with the road surface, vehicle load, driving speed, steering operation, etc. Tires are key components that are in direct contact with the ground. The degree of wear not only affects the vehicle's driving performance, but is also closely related to driving safety.

[0003] Common tire wear measurements are mostly performed by placing the tire on a measuring stand and manually measuring the tire tread depth using a professional tool that measures the tire tread depth. After the measurement, the degree of tire wear is determined based on the measured data.

The mounting frame 1201 is fixed on the arc-shaped platform 11, the second motor 1202 is fixed on the mounting frame 1201, the worm 1203 is fixed on the output shaft of the mounting frame 1201, and the worm wheel 1204 is fixedly sleeved on the T-shaped turntable 12, and the worm wheel 1204 and the worm 1203 are meshed with each other.

[0035] It should be noted that the clamping members are symmetrically arranged about the axis of the arc-shaped stand 11, so that the forces on both ends of the tire are stable during the clamping process.

[0036] It should be noted that the display screen 4, the drive motor 51, the first motor 1102, the second motor 1202, the laser scanner 10 and the pressure sensor 35 belong to the existing technology in this field. The specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated.

[0037] The use method and advantages of the present invention: When the tire wear measuring device is used, the working process is as follows: When testing a tire, first place the tire to be tested between the two clamping plates 14. By rotating the knob 1402, the screw 1401 can be rotated in or out of the T-shaped turntable 12, thereby driving the clamping plates 14 to move closer or farther away from each other, thereby achieving the clamping or loosening operation of tires of different specifications, ensuring that the tire can be stably fixed on the stand during the measurement process. Then, the driving machine 51 is started to drive the screw 52 to rotate. As the screw 52 rotates, the slider 6 will be prompted to move up and down and slide along the screw 52, ​​thereby driving the fixed tire to slide down onto the elastic pad 3. At this time, the laser scanner 10 and the second motor 1202 are synchronously started. When the second motor 1202 is started, its output shaft drives the worm 1203 to rotate. The meshing action of the worm 1203 and the worm wheel 1204 enables the T-shaped turntable 12 to drive the tire body 15 to rotate at a uniform speed around its own axis, thereby achieving stable rotation of the tire on the stand, and cooperating with the laser scanner 10 to complete the scanning of the entire circumferential surface of the tire. The three-dimensional contour data of the tire surface is measured, and the data is transmitted to the display screen 4 for display. At the same time, the tire will contact the elastic pad 3 during rotation. When in contact, the weight of the tire will cause the elastic pad 3 to deform, thereby pressing the piston rod 32 in the elastic member to move downward, and the spring 34 is compressed. The pressure sensor 35 can sense the pressure change in real time and transmit the pressure data to the display screen 4 for display. By analyzing the deformation data of the elastic pad 3 and the pressure data collected by the pressure sensor 35, the wear condition of the tire can be assisted to be judged from the side. When it is found that the deformation degree of the elastic pad 3 is significantly greater than the deformation degree when the new tire is placed, or the pressure distribution collected by the pressure sensor 35 is significantly different from that when the new tire is placed, it indicates that the tire has more serious wear. It is necessary to further carefully analyze the three-dimensional contour data obtained by the laser scanner 10 to determine the specific wear condition, so as to make a more precise measurement of the tire wear degree and make the measurement more comprehensive.

[0038] When it is necessary to measure different inclination angles of the tire, start the first motor 1102, and its output shaft drives the transmission shaft 1103 to rotate, and the gear 1004 on the transmission shaft 1103 rotates accordingly. The meshing action of the gear 1004 and the arc rack 1105 enables the arc stand 11 to rotate and adjust around the support rod 9, thereby adjusting the angle of the tire in the horizontal direction, so that the laser scanner 10 can scan the tire from different horizontal angles, further improving the comprehensiveness and accuracy of the measurement.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.

When the two are in contact, the weight of the tire causes the elastic pad (3) to deform. The embossing of the tire contacts the upper surface of the elastic pad (3) and is embedded in the measuring chamber (31), thereby forcing the piston rod (32) to move downward to produce a squeezing effect, causing the spring (34) to be compressed and elastically deformed. At the same time, the pressure is transmitted to the pressure sensor (35) through the piston rod (32). The pressure sensor (35) can sense the pressure change in real time, convert the measured pressure value into an electrical signal and transmit it to the display screen (4), thereby determining the specific wear condition of the tire, thereby making the measurement of the tire wear degree more precise and making the measurement more comprehensive. S5: Tire measurement angle adjustment: The transmission shaft (1103) is driven by the first motor (1102) to drive the gear (1004) to rotate, and the meshing action of the gear (1004) and the arc-shaped rack (1105) enables the arc-shaped platform (11) to be rotated and adjusted around the support rod (9), thereby adjusting the angle of the tire in the horizontal direction, so that the laser scanner (10) can scan the tire from different horizontal angles, further improving the comprehensiveness and accuracy of the measurement.
