Description

Technical Field

[0001] The utility model relates to the field of sensors, in particular to a laser sensor device for measuring the appearance dimensions of a tire. Background Art

[0002] When the laser sensor is working, the laser emitting diode first aims at the target and emits a laser pulse. After being reflected by the target, the laser is scattered in all directions. Part of the scattered light returns to the sensor receiver and is received by the optical system and imaged onto the avalanche photodiode. The avalanche photodiode is an optical sensor with an internal amplification function, so it can detect extremely weak light signals and convert them into corresponding electrical signals. The most common one is the laser rangefinder sensor, which can measure the target distance by recording and processing the time from the light pulse being emitted to the time it is returned and received. A Chinese patent discloses a three-dimensional laser sensor for measuring the appearance size (authorization announcement number CN 208075775 U), this patented technology can provide a buffer device, a snap-on plate and a movable plate, and use the buffer device to buffer the bottom of the sensor body, thereby reducing the vibration of the sensor in the vertical direction, and use the automatic resilience of the reset spring to prompt the snap-on plate to fix the side of the sensor body, thereby reducing the vibration of the sensor in the horizontal direction. By limiting the vertical and horizontal directions, the purpose of stable placement is achieved, and the situation of easy shaking is reduced, thereby improving the accuracy of the measurement data. However, this design uses a multi-spring structure to achieve buffering, so as to achieve the function of stable placement. When the use cycle is too long, the spring is prone to elastic deformation, resulting in functional failure. Therefore, those skilled in the art provide a laser sensor device for measuring the appearance size of a tire to solve the problems raised in the above background technology. Utility Model Content
