[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, the high-speed rail seat button durability pressing test device includes a support frame 1, and a test component is provided at the top of the support frame 1.

[0025] The test assembly includes a lifting frame 2 mounted on the top of a support frame 1. A retaining rod 4 is rotatably connected to the outer wall of the lifting frame 2 via a universal joint 3. A test seat 5 is fixedly connected to the end of the retaining rod 4. A reciprocating screw 6 is rotatably connected to the outer wall of the test seat 5. A displacement seat 7 is threaded onto the outer wall of the reciprocating screw 6 and slides on the inner wall of the test seat 5. A drive assembly is provided on the outer wall of the displacement seat 7.

[0026] The drive assembly includes a clamping seat 8 fixedly connected to the outer wall of the displacement seat 7. A clamping block 10 is fixedly connected to the inner wall of the clamping seat 8 by a compression spring 9. A cylinder 11 is clamped in the inner wall of the clamping block 10. A test bag 12 is installed at the end of the cylinder 11. A drive motor 13 is installed at the end of the reciprocating screw 6.

[0027] An air pump 14 is installed at the top of the support frame 1, and the output end of the air pump 14 is fixedly connected to the input end of the test bag 12 through a hose 15.

[0028] An electric push rod 16 is installed on the outer wall of the lifting frame 2. The output end of the electric push rod 16 is rotatably connected to a rotating seat 18 via a rotating shaft 17. The end of the rotating seat 18 is fixedly connected to the bottom end of the retaining rod 4.

During testing, the cylinder 11 operates to continuously press the button. Furthermore, by activating the air pump 14, compressed gas is delivered to the test bag 12 through the hose 15, causing it to expand rapidly. Then, the controller 19 operates the pre-written execution code, which, through the air pump 14, drive motor 13, and electric motor... The coordination of the push rod 16, the cylinder 11, and the electric push rod 16 drives the cylinder 11 to adjust the angle when pressed, and the drive motor 13 adjusts the height of the press. The inflation size of the test bag 12 is used to simulate the size of different passengers' fingers, and the button is pressed from different angles to improve the completeness of the test data. Since the retaining rod 4 is connected to the outer wall of the lifting frame 2 through the universal joint 3, and the output end of the electric push rod 16 is connected to the retaining rod 4 through the rotating shaft 17 and the rotating seat 18, there will be no jamming during angle adjustment.
