[0002] A steering wheel inclination meter (inclinometer for short) is a device used to measure the inclination of a vehicle's steering wheel. It usually consists of an inclination sensor and a display. By detecting the inclination angle of the steering wheel, it can help the driver understand the position and inclination of the steering wheel during the operation of the vehicle.

[0003] Due to long-term use or other reasons, the inclinometer may have errors and needs to be calibrated regularly. Among them, the inclinometer calibration frame is a common device used to calibrate and verify the inclinometer. It usually consists of a fixed bracket and a reference standard with a known angle. The inclinometer can be installed on the calibration frame and then compared with the reference standard to determine the error of the inclinometer and make corresponding corrections and adjustments.

[0025] How it works: See Figure 4The inclinometer can be inserted into any group of mounting holes 4 on the calibration plate 2 according to the measurement needs. The specific operation method is: first, pull one of the pull blocks 6 forward, the pull block 6 will drive the pressure plate 5 on it to leave the calibration plate 2 and move forward, the pressure plate 5 will drive the two slide bars 9 on it to slide forward in the inner wall of the calibration plate 2, and the two slide bars 9 will drive the discs 10 on each of them to move forward together (in this process, the springs 8 between the two discs 10 and the calibration plate 2 will be squeezed on the outer walls of their corresponding slide bars 9), and then pull the pull block 6 without letting go. At the same time, one of the pancake-shaped mounting disks on the inclinometer is inserted between the pressure plate 5 and the calibration plate 2, and then the pull block 6 is released. Under the action of the two springs 8, the pressure plate 5 will immediately move backward and fit tightly with the pancake-shaped mounting disk on the inclinometer. Similarly, according to the same operation, the other pancake-shaped mounting disk on the inclinometer can be placed between the other pressure plate 5 and the calibration plate 2, and the inclinometer can be clamped between the calibration plate 2 and the two pressure plates 5, so that the inclinometer can be inserted into the calibration plate 2 more firmly and easily, thereby further improving the calibration accuracy.
