Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle roof static pressure testing, and in particular relates to a vehicle roof static pressure testing displacement sensor detection system, detection method, terminal and application. Background Art

[0002] As an independent automotive component, the car roof undergoes post-production testing to ensure proper fit with the vehicle body. This testing process often requires support. Existing technologies typically place the car roof directly on a testing table for testing. To achieve this, existing techniques simply apply tape to the bottom of the vehicle body before testing and then measure the extent of the penetration of the vehicle body into the tape to determine the displacement. This method suffers from low measurement accuracy.

[0003] Furthermore, during the inspection process, a roof quality inspection device is needed to inspect the quality of the car. Traditional quality inspection devices are not very safe and are prone to damage due to excessive pressure, which shortens the service life of the quality inspection device, increases costs, reduces work efficiency, and brings inconvenience to users.

[0004] Through the above analysis, the problems and defects of the existing technology are as follows:

[0005] (1) In the existing technology, the height and angle of the displacement sensor cannot be adjusted according to the actual situation, resulting in low measurement accuracy of the vehicle displacement. It cannot guarantee accurate measurement of the displacement and real-time data collection during vehicle body experiments.

[0006] (2) In the existing vehicle body displacement measurement, the operation is complicated, the cost of raw materials is high, and the measurement efficiency is low.

[0007] The difficulty of solving the above problems and defects is:

[0008] (1) When detecting the displacement of different parts of the vehicle side, it is necessary to assemble many iron blocks together to reach the height of the detection position, and then connect the displacement sensor to the detection position. Since the iron blocks are heavy and difficult to move and adjust, this task is quite difficult.

[0009] (2) The displacement sensor is small in size and cannot be firmly fixed on the iron block.

[0010] (3) Using tape to detect displacement cannot guarantee the accuracy of measurement.

[0011] The significance of solving the above problems and defects is that when the vehicle roof is subjected to downward pressure from the pressure plate of the test equipment, the Y-axis displacement of the vehicle body can be accurately measured, thereby determining whether the test data is valid. Summary of the Invention

[0029] According to a fourth aspect of the disclosed embodiment, a computer program product stored on a computer readable medium is provided, including a computer readable program, which, when executed on an electronic device, provides a user input interface to implement the roof static pressure test displacement sensor detection method.

[0030] According to a fifth aspect of the disclosed embodiment, an information data processing terminal is provided, including a memory and a data collector, the memory stores a computer program, and the computer program is executed by the data collector to enable the data collector to perform the following steps.
