[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] See Figure 1 As shown, a durability testing device for a touch-sensitive switch for an electric door includes a test bench 1. The test bench 1 is equipped with a mounting bracket 2 for mounting the touch-sensitive switch under test and an actuator 3 for performing durability testing on the touch-sensitive switch. The actuator 3 is connected to a power mechanism 4, which provides power to the actuator 3 to achieve operation, thereby enabling the touch action on the touch-sensitive switch. The power mechanism 4 is an air compressor. The device also includes a control system 5, which is electrically connected to the actuator 3. The control system 5 can control the frequency and number of movements of the actuator 3.

[0025] For further details, please refer to [link / reference]. Figure 1 As shown, the cross-section of the mounting bracket 2 is inverted T-shaped. During installation, the horizontal connecting plate of the mounting bracket 2 is locked onto the test bench 1 by corresponding locking bolts, and the touch sensor switch under test is mounted on the vertical connecting plate of the mounting bracket 2. At this time, the touch sensor switch under test is opposite to the actuator 3, which facilitates the actuator 3 to perform touch action on the touch sensor switch, thereby realizing the durability test operation.

[0026] Further, see Figure 2-4 As shown, the actuator 3 includes an L-shaped connecting seat 31. The horizontal connecting plate of the connecting seat 31 is locked onto the test bench 1 by corresponding locking bolts. A pen-type cylinder 32 is provided on the vertical connecting plate of the connecting seat 31. The pen-type cylinder 32 is connected to a solenoid valve 33 through a corresponding air pipe, and the front end of the piston rod of the pen-type cylinder 32 is provided with a touch protection end 34. When connected, the solenoid valve 3 is connected to the power mechanism 4 through a corresponding air pipe, and the solenoid valve 33 is electrically connected to the control system 5. During operation, the control system 5 controls the on / off state of the solenoid valve 3, thereby changing the direction of the air supply provided by the power mechanism 4 to the pen-type cylinder 32, thereby realizing the extension and retraction movement of the piston rod of the pen-type cylinder 32, thereby realizing the repeated touch action of the touch-sensitive switch, and thus realizing the durability test of the touch-sensitive switch.

[0027] Among them, see Figure 2As shown, a pair of magnetic switches 35 are provided on the outer surface of the pen-type cylinder 32. The magnetic switches 35 are electrically connected to the control system 5. Through the magnetic switches 35, the extension and retraction position of the piston rod of the pen-type cylinder 32 can be monitored in real time, and the position signal is fed back to the control system 5. This allows the control system 5 to accurately control the movement stroke of the piston rod of the pen-type cylinder 32, thereby more precisely controlling the touch action of the touch-sensitive switch and ensuring the accuracy and reliability of the durability test. Of course, the above method of controlling the extension and retraction position of the piston rod of the pen-type cylinder 32 is only one embodiment and is not intended to limit the scope of this application. In actual implementation, other methods can also be used, for example: see [link to relevant documentation]. Figure 3 As shown, an adjusting sleeve 36 and a locking nut 37 are threadedly connected to the piston rod of the pen-type cylinder 32. During adjustment, the position of the adjusting sleeve 36 on the piston rod of the pen-type cylinder 32 is adjusted to control the retraction position of the piston rod, thereby achieving precise adjustment of the effective stroke of the piston rod and thus more accurately controlling the touch action of the touch-sensitive switch, ensuring the accuracy and reliability of durability testing; or, see Figure 4 As shown, a pair of magnetic switches 35 are provided on the outer surface of the pen-type cylinder 32. At the same time, an adjusting sleeve 36 and a locking nut 37 are threadedly connected to the piston rod of the pen-type cylinder 32. It should be noted that when both are provided, the magnetic switches 35 control the effective stroke of the piston rod of the pen-type cylinder 32 to be slightly less than that of the adjusting sleeve 36. This achieves a dual stroke control method during the testing process, with the magnetic switches 35 as the main control and the adjusting sleeve 36 as the auxiliary control, ensuring the smooth progress of the testing.

[0028] The working principle of this utility model is as follows:

[0029] During testing, the touch sensor switch under test is first installed on the mounting bracket 2. Then, the device is powered on, and after powering on, the operator sets the passage time and number of passages of the control solenoid valve 3 through the control system 5 according to the test requirements, that is, the movement frequency and the number of cycles (2.5 million times) are set. Then, the device is started. At this time, the power mechanism 4 is started and supplies air to the pen-type cylinder 32 through the solenoid valve 3, so as to realize the reciprocating movement of the piston rod of the pen-type cylinder 32, thereby realizing the repeated touch action of the touch sensor switch, and thus realizing the durability test of the touch sensor switch.

[0030] It should be noted that, in this embodiment, the touch sensing area of ​​the tested touch-sensitive switch is equipped with 8 green LED indicators and 8 red LED indicators. When the sensing area is not touched, the 8 green LED indicators are always on, and the 8 red LED indicators are off. When the sensing area is touched, the 8 green LED indicators turn off, the 8 red LED indicators turn on and remain on for 300ms before turning off, and then the 8 green LED indicators turn on again.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
