Specifically, the tire width measuring device for a wheel balancer of the present embodiment is a measuring method at the time of putting into use as follows:

when the width of the tire needs to be measured, a user pulls the tire shield elbow 2, and the device assembly 1 changes the position along with the tire shield elbow 2, so that the angle sensor 43 senses the change of angle data. In the state of fig. 5, the angle data determined by the angle sensor 43 in the device assembly 1 is 90 degrees, and the voltage value of the pin 12 of the U2 chip in fig. 3 is 1.0V, as shown in the state of fig. 6. When the tire shield elbow 2 moves to the state shown in fig. 7, the angle data judged by the angle sensor 43 in the device assembly 1 is smaller than 90 degrees, and the voltage value of the pin 12 of the U2 chip in fig. 3 is 1.0V, as shown in the state shown in fig. 8. The working state of the whole device assembly 1 is triggered along with the position change of the tire shield elbow 2, namely:

A. illuminating the laser pointer 42 while the angle data is changing to enable the pointing and positioning function of the laser pointer 42; the user stops slightly after the laser pointer 42 indicates the measurement area (referring to the area indicated by the ellipse in fig. 9) according to the positioning indicated by the laser pointer 42, for example, the tire shield elbow 2 is kept still for at least a preset time period, which may be 3S or more or less;

B. driving the radar ranging unit 41 when the angle data is smooth and stable within a continuous preset time period, and measuring a distance value between the radar ranging unit 41 and the tire to be measured by the radar ranging unit 41; the smooth and stable default of the angle data within the continuous preset time period indicates that the radar ranging unit 41 is aligned with the tire to be measured, and the smooth and stable data indicates that the angle data has no large fluctuation, namely the tire protective cover bent pipe 2 does not move any more; for example, in the present embodiment, the tire shield elbow 2 is rotated to the state shown in fig. 9 and 10 and is kept for the preset time so that the radar ranging unit 41 can obtain the distance value;

C. tire width is calculated from the distance values and tire width data is sent to the wheel balancer system. When a tire to be measured is not installed, the distance value measured by the radar ranging unit 41 is a, when the tire is installed, the distance value measured by the radar ranging unit 41 is B, the distance value B measured at this time is reduced compared with the distance value a, the reduced value is the width of the tire, namely, a-B is the tire width, wherein the value a is fixed, and the value a is stored in the main control module 46 in advance, and when the tire width is measured, the measured distance value B is directly subtracted from the value a, which is the tire width measured at this time.

Preferably, the laser indicator 42 is turned off after the step B or the step C is completed, that is, the laser indicator 42 is turned off after the distance value is measured or the tire width is transmitted, so as to achieve the purposes of energy saving and environmental protection and reduce the energy consumption of the machine.
