Description

Technical Field

[0001] The present application relates to the technical field of sensor detection devices, and in particular to a vehicle body height sensor detection device. Background Art

[0002] The vehicle height sensor, also known as the axle height sensor, vehicle posture sensor or suspension height sensor, is an essential component used to measure the changes in the front and rear suspension postures of the vehicle body. The sensor uses the photoelectric principle to install the sensor body at the end of the vehicle body, and converts the up and down movement of the suspension into the rotational movement of the disk slot through the control link. The change in the output of the photointerrupter is used to detect the vehicle height and convert it into an electrical signal to input the control device. In the field of vehicle height monitoring, the vehicle height sensor is a key component.

[0003] Reference Figure 1 The main body 1 is usually composed of a sensor body 11, a first link 12, a second link 13, and a fixing plate 14 fixed to a moving part of the vehicle body (such as a suspension). The working principle of this sensor is that the two ends of the first link 12 are respectively hinged to the sensor body 11 and the end of the second link 13, and the other end of the second link 13 is hinged to the fixing plate 14, forming a variable angle system. When the moving part of the vehicle body (such as the suspension) is displaced, the angle of the first link 12 and the second link 13 will change, thereby changing the angle between them. The change in this angle is detected by the sensor body 11, thereby indirectly reflecting the change in the height of the vehicle body.

[0004] However, before the vehicle height sensor leaves the factory, a simulation test must be carried out to ensure that its performance meets the standard. At present, during the test of the existing simulation test equipment, in order to ensure its installation stability, the operator is required to fix the sensor to the test equipment with bolts. This step is not only cumbersome to operate, but also inconvenient for subsequent disassembly and assembly, which greatly increases the test time and leaves room for improvement.
