[0022] As Figures 1 - 3As shown in the figure, an automotive electric window switch durability test device includes a workbench 1 and a test component 6. A fixed bracket 2 is fixedly installed on the top of the workbench 1, and first fixing plates 3 are symmetrically installed on the left and right at the top of the fixed bracket 2. Moreover, a first motor 4 is installed at the top left of the fixed bracket 2, and the output shaft of the first motor 4 is installed with a driving lead screw 5 through a coupling. The test component 6 is slidably connected to the inner surface of the top of the fixed bracket 2. The test component 6 includes a bearing bracket 61, a cross-shaped slider 62, a connecting mechanism 63, a T-shaped slide bar 64, a second motor 65, and a reciprocating pressing mechanism 66. A cross-shaped slider 62 is fixedly installed on the top of the bearing bracket 61, and a connecting mechanism 63 is fixedly connected to the top of the cross-shaped slider 62. Moreover, the inside of the connecting mechanism 63 is movably connected to the side of the driving lead screw 5. At the same time, T-shaped slide bars 64 are symmetrically installed on the front and back of the top of the bearing bracket 61. The top of the bearing bracket 61 is fixedly connected to the bottom of the T-shaped slide bars 64. And the bearing bracket 61 and the fixed bracket 2 form a sliding structure through the T-shaped slide bars 64. By setting the bearing bracket 61 and the fixed bracket 2 into a sliding structure, when the bearing bracket 61 moves along the inner surface of the top of the fixed bracket 2, it is smoother and more stable. A second motor 65 is installed on the outside of the bearing bracket 61, and the output shaft of the second motor 65 is installed with a reciprocating pressing mechanism 66 through a coupling. The reciprocating pressing mechanism 66 includes a driving wheel 661, a connecting shaft 662, a first connecting rod 663, a connecting plate 664, a second connecting rod 665, and a second fixing plate 666. A connecting shaft 662 is fixedly connected to the outside of the driving wheel 661, and the other end of the connecting shaft 662 is rotatably connected to the inside of the bearing bracket 61. Moreover, a first connecting rod 663 is fixedly installed on the inside of the driving wheel 661. At the same time, the outside of the first connecting rod 663 is movably connected to a connecting plate 664. The other end inside the connecting plate 664 is movably connected to a second connecting rod 665. And the end of the second connecting rod 665 is fixedly connected to a second fixing plate 666. The inside of the connecting plate 664 is rotatably connected to the outer surface of the second connecting rod 665, and the end of the second connecting rod 665 is fixedly connected to the inside of the second fixing plate 666. And the second fixing plate 666 and the connecting plate 664 form a rotating structure through the second connecting rod 665. By setting the second fixing plate 666 and the connecting plate 664 into a rotating structure, when the second motor 65 drives the driving wheel 661 to rotate inside the bearing bracket 61, it can stably drive the bearing plate 7 to move up and down reciprocally along the inner surface of the bearing bracket 61. And the bottom of the second fixing plate 666 is fixedly connected to the top of the bearing plate 7. And a bearing plate 7 is installed at the bottom of the test component 6. T-shaped sliders 8 are symmetrically installed on the left and right sides of the bearing plate 7. Moreover, pressing rods 9 are installed at equal distances in an array at the bottom of the T-shaped sliders 8. At the same time, a rubber protection pad 10 is fixedly connected to the bottom of the pressing rod 9.

[0023] As Figure 1 、Figure 2 and Figure 4 As shown in Figure 4 , a fixed bracket 2 is fixedly installed on the top of the workbench 1, and first fixing plates 3 are symmetrically installed on the left and right of the top of the fixed bracket 2. A first motor 4 is installed on the left top of the fixed bracket 2, and a driving lead screw 5 is installed on the output shaft of the first motor 4 through a coupling. The test assembly 6 is slidably connected to the inner surface of the top of the fixed bracket 2. A carrier 11 is slidably connected to the front and back of the top of the workbench 1. A third fixing plate 12 is fixedly installed on the top of the workbench 1, and a limiting assembly 13 is slidably connected to the top of the workbench 1. The limiting assembly 13 includes a positioning plate 131, a threaded adjusting rod 132, and a rectangular slider 133.

Rectangular sliders 133 are symmetrically installed on the left and right of the bottom of the positioning plate 131. The bottom of the positioning plate 131 is fixedly connected to the top of the rectangular slider 133. The positioning plate 131 is slidably connected to the workbench 1 through the rectangular slider 133. By setting the positioning plate 131 and the workbench 1 to a sliding structure, the positioning plate 131 moves more smoothly and stably along the top of the workbench 1.

[0024] In summary, for this automobile electric window switch durability test device, first according to Figures 1 to 4In the structure shown, the staff places the switch to be tested selected by random inspection on the top of the carrier 11. Then, the staff pushes the carrier 11 so that the carrier 11 drives the switch to move towards the bottom of the test assembly 6. When the switch moves directly below the carrier plate 7, the staff stops pushing further. Then, the staff turns on the first motor 4 through the controller. When the first motor 4 starts running, it drives the drive screw rod 5 to rotate inside the first fixing plate 3. At this time, through the connection of the connecting mechanism 63 and the sliding of the cross-shaped slider 62 and the T-shaped slide bar 64, the carrier bracket 61 drives the carrier plate 7 to move left and right along the inner surface of the top of the fixing bracket 2. When the pressing rod 9 moves directly above the switch button, the staff turns off the first motor 4. Then, the staff grabs the threaded adjusting rod 132 and drives it to rotate outside the abutting plate 131. At this time, through the threaded connection between the side of the threaded adjusting rod 132 and the thread inside the third fixing plate 12 and the sliding of the rectangular slider 133, the abutting plate 131 moves towards the outside of the carrier 11 along the top of the workbench 1. When the inner side of the abutting plate 131 is in fitting connection with the outside of the carrier 11, the staff stops rotating the threaded adjusting rod 132, which provides convenience for the staff to detect the durability of subsequent switches of the same size. Then, the staff turns on the second motor 65 through the controller. When the second motor 65 starts running, it drives the connecting shaft 662 to rotate inside the carrier bracket 61, so that the connecting shaft 662 drives the first connecting rod 663 to rotate inside the carrier bracket 61. Then, through the connection and cooperation of the first connecting rod 663, the connecting plate 664 and the second connecting rod 665 and the sliding of the T-shaped slider 8, the second fixing plate 666 drives the carrier plate 7 to move up and down reciprocally along the inner surface of the carrier bracket 61, so that the carrier plate 7 drives the pressing rod 9 to perform repetitive and rapid loosening and pressing on the switch button, so as to achieve the purpose of automatically testing the durability of the switch button. And through the cooperation of the rubber protection pad 10, the pressing rod 9 will not cause serious wear to the outer surface of the switch when pressing the switch.
