[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3As shown, a vehicle rear center armrest cup holder opening and closing test device includes a machine platform 10, a positioning mechanism 20, a pressure mechanism 30 and a displacement testing mechanism 40. The positioning mechanism 20 includes a bracket 21 and a quick clamp 22. The bracket 21 is arranged on the machine platform 10 to support and position a product 100 (i.e., a rear center armrest with a retractable cup holder). Three quick clamps 22 are arranged on the bracket 21 to press the product 100. The pressure mechanism 30 includes a driving component 31, a pressure sensor 32 and a profiling pressure head 33. The driving component 31 is arranged on a stand 301 fixed on the machine platform 10. The pressure sensor 32 is arranged at the output end of the driving component 31. The profiling pressure head 33 is arranged on the pressure sensor 32 and acts on the cup holder of the product 100 through driving. The pressure sensor 32 receives and feeds back the pressure data received by the profiling pressure head 33. The displacement testing mechanism 40 includes a laser sensor. The laser sensor is arranged on the machine platform 10 and located on the opposite side of the positioning mechanism 20 to measure and feed back the horizontal movement distance of the cup holder.

[0027] In the present invention, the product 100 (the rear center armrest with a retractable cup holder) is placed on the bracket 21 for support, and the quick clamp 22 is used to press the product 100 down to fix the product position. The driving component 31 drives the pressure sensor 32 and the contour pressure head 33 to abut against the cup holder on the product 100 and apply pressure in the horizontal direction. During this process, the pressure sensor 32 feeds back the pressure (reaction force) data received. After the contour pressure head 33 applies pressure and moves a corresponding distance (the distance from the cup holder to the point where it can rebound and open after being pressed), the contour pressure head 33 moves in the driving component 31. The driving component 31 moves in the opposite direction by a corresponding distance (the maximum distance after the cup holder is opened) to avoid hindering the cup holder from popping out. During this process, the laser sensor receives the position signal of the cup holder for feedback and can record the required time in this process. After completing the above action, the driving component 31 drives the contour pressing head 33 to close the cup holder. During the process of the cup holder moving to the bottom and closing, the pressure sensor 32 feeds back the pressure (reaction force) data received. The data obtained through the above action test is the force required for opening / closing the cup holder, as well as the opening degree and opening time of the cup holder.

[0028] The utility model fixes the product 100 through the positioning mechanism 20, drives the pressure sensor 32 and the contoured pressure head 33 to open and close the cup holder on the product 100 through the driving component 31, so as to test the force required to open / close the cup holder, and feeds back the position of the cup holder in the closed state and the maximum open state through the laser sensor, so as to test the openability and opening time of the cup holder, and ensures the accuracy and efficiency of the test through the automated testing method.

[0029] More specifically, the pressure sensor 32 provides real-time feedback, with an accuracy of ±0.01N, a stroke of 50N, and an actual measured opening force; the laser sensor tests the displacement of the cup holder from closed to open, determines the opening time, meets the accuracy of 0.01S, and measures the opening time.

The middle part of the screw rod 2133 is provided with an external thread, which passes through the threaded hole 213b and is screwed to the first mounting plate 2131. Therefore, the position of the first push plate 2132 can be moved by rotating the screw rod 2133, so that the contact position between the first push plate 2132 and the product 100 is changed, so that the end of the product 100 with the cup holder can be placed within the action range of the contoured pressure head 33 to adapt to products 100 of different lengths. In order to ensure the convenience of operating the screw rod 2133, a rotating cap can be provided at the end of the screw rod 2133 for easy hand-held operation.

A through hole is provided on the second mounting plate 2141, one end of the guide rod is connected to the second push plate 2142, and the other end passes through the through hole. A spring is provided on the guide rod between the second mounting plate 2141 and the second push plate 2142, and the spring is respectively abutted against the second mounting plate 2141 and the second push plate 2142 to achieve the compressibility and resilience of the spring, and the guide rod is prevented from being separated from the second mounting plate 2141 by a limit ring arranged on the end of the guide rod away from the second push plate 2142.
