Utilize the utility model discloses the process of test electric stay rod performance as follows:
(1) fixing the testing device on a vertical plane, enabling the first clamping unit to be located above the upper clamping unit and the second clamping unit to be located below the upper clamping unit, and enabling an electric support rod fixed in the testing device to be in a vertical direction; clamping the electric stay bar assembly in a testing device, and sending an alarm to confirm that the electric stay bar assembly is placed in place after a pressure alarm senses preset 50N pressure, wherein the sliding block is positioned at the original point of the sliding block;
(2) when a first power supply is switched on, a sliding table servo motor starts to rotate, an output shaft of the sliding table servo motor drives a screw rod to rotate, the screw rod drives a sliding block to move linearly upwards at the speed of 300mm/min, the sliding block moves forwards to push a second clamping unit to compress an electric support rod, when a force sensor senses the pressure of 100N of the sliding block, the displacement d of the sliding block is recorded, and at the moment, the compression stroke of the electric support rod is 0;
(3) when the slide block reaches the set maximum displacement LmaxThen, the sliding table servo motor rotates reversely, the sliding block moves linearly downwards at the speed of 300mm/min, the electric support rod stretches and releases, and when the sliding block moves to LmaxRecording 10 sets of force value data when the thickness is minus 10mm plus or minus 0.5mm, and calculating to obtain an average value F1(ii) a When the slide displacement is 10 +/-0.5 mm, 10 groups of data are recorded, and the average value F is obtained by operation2；

Compared with the same industry, the power of the stay bar product is derived from the internal spring, and the force values of two position points at the opening and closing moments of the automobile tail door are more important. Tail gate open state, slider displacement LmaxAt the position of-10 mm, the force is enough to open the door, the weight of the tail gate is overcome, and when the tail gate stretches to the highest point, the position is marked as 10mm of displacement of the sliding block, and at the moment, the electric stay bar can support the tail gate and cannot slide off. We therefore believe that the motorized brace as a safety regulation requires reinforcement of this control point for the spring itself, for the compression-extension stroke LmaxThe force values at-10 mm and 10mm need to be met, and in our above it is said that during compression and extension, the motor of the electric strut is not energized, while the spring needs to meet the corresponding force values at these two points (tolerance ± 40N).
