[0063] Method for measuring force using a hinge device of an automobile hinge:

[0064] S1. Input the qualified force value range of the hinge to be tested in the display device;

[0065] In this embodiment, the qualified range of the force value of the hinge test is 40-50N, and the lower limit of the qualified parameter of the force value in the display device 210 is set to 40N, and the upper limit is set to 50N.

[0071] S4, determining a force value of the test hinge based on the measurement of the sensor;

[0072] If the hinge force value is above 40N and below 50N, it is a qualified product.

[0073] If the tested hinge force value is less than 40N or greater than 50N, it is a defective product.

[0074] S5. Based on the test results, the alarm device responds.

[0075] After receiving the signal, the alarm device 230 starts up and issues an alarm.

[0076] It is worth mentioning that this solution can also be used to test the durability of hinges. The details are as follows:

[0077] 1. By driving the third power source 3222, the opening and closing cycle of the hinge is simulated to test the durability of the hinge during repeated use;

[0078] 2. Through intermittent testing, set a certain number of cycles or time periods to simulate actual usage;

[0079] 3. The load applied to the hinge is adjusted by adjusting the second driving source 3215 to simulate the use of different armrest boxes and opening forces, and to evaluate the durability of the hinge when subjected to different loads.

[0080] A display device 210 is equipped for data recording and analysis system, which automatically records the opening angle, closing force, number of cycles and other data during the test process for subsequent analysis and evaluation; the speed of opening and closing of the hinge is adjusted to simulate the opening and closing speeds under different usage conditions, so as to evaluate the performance of the hinge under high-speed or low-speed operation.
