Description

Switching key life detecting device

The invention relates to a life detecting device for a switching key, in particular to a life detecting device capable of automatically switching a switching key and calculating the number of switching times.

The switching key is a common component in the electronic device, and the switching key is mainly changed by the position to change the power supply state or set the electronic device in different functional states.

Referring to FIG. 1 , it is a schematic diagram of a prior art electronic device 10 , including a body 12 and a switch button 14 . The surface of the body 12 is provided with a sliding slot 16 having at least a first position 161 and a second position 162 on the sliding slot 16, wherein the switching button 14 can be in the first position 161 and the second position of the sliding slot 16 The reciprocating movement between the 162s causes the electronic device 10 to set the electronic device 10 in a different state by changing the position of the switching key 14.

In order to ensure the reliability of the switch button 14 of the electronic device 10, the electronic device 10 of the prior art must pass the life test before leaving the factory. The test method mainly uses the manual life test, and the switch is turned back and forth through the tester's finger. The key 14 records the number of times of the dialing and whether the function of the switching key 14 is normal. However, by manually performing the life test of the switch key 14, in addition to the force control of the dialing force, the tester must also remember the brain. Recalling the number of times the switch button 14 is toggled, the tester's brain is easily mistaken for fatigue, greatly affecting the accuracy of the life test of the switch button 14.

Therefore, if it is possible to solve the shortcomings of the prior art, it is proposed that the life detecting device of the switching key replaces the manual test, not only can the force of the toggle switching key be averaged, but also the number of times the switching key is toggled can be accurately recorded, thereby improving the switching key. The accuracy of the life detecting device.

Please refer to FIG. 2 , which is a schematic diagram of the life detecting device 20 of the switching key 10 of the present invention, comprising a motor 21 , an elliptical eccentric 22 , a driving guide 23 , a linear bearing 24 , an inductor 25 , and a count The device 26, a stage 27, a start switch 28 and a stop switch 29.

Referring to FIG. 3 , which is a schematic diagram of the motor 21 and the elliptical eccentric 22 of the present invention, the motor 21 used in the present invention is preferably an adjustable speed motor with an electromagnetic brake, and has an output shaft. 211, the elliptical eccentric 22 is coupled with the output shaft 211, and has a long shaft 221. The driving guide plate 23 has a guiding slot 231 and a dialing block 232, wherein the guiding slot 231 is coupled to the elliptical eccentric 22 In conjunction, the dial block 232 is coupled to the switch button 14 of the electronic device 10. The linear bearing 24 is for guiding the drive guide plate 23 to move in the first direction, and the counter 26 is used for The recording sensor 25 senses the number of rotations of the motor 21, and the stage 27 is for fixing the electronic product 10 to prevent the life detecting device 20 from swaying during the process of dialing the switching key 14, and the starting switch 28 is activated. The stop switch 29 is for controlling the rotation and stop of the motor 21.

Please refer to FIG. 4A to FIG. 4E, which are schematic diagrams showing the movement of the elliptical eccentric 22 to drive the driving guide plate 23. Taking the elliptical eccentric wheel 22 counterclockwise as an example, when the elliptical eccentric wheel 22 is rotated by 90 degrees (as shown in FIG. 4B), it will drive the guiding groove 231 of the driving guide plate 23 to the left, and the dialing block 232 will be The driving switch 14 is moved to the first position 161, and when the elliptical eccentric 22 is rotated by 270 degrees (as shown in FIG. 4D), it will drive the guiding groove 231 of the driving guide plate 23 to the right, and the dial block 232 is moved. The switching key 14 is moved to the second position 162.

It can be seen from the above description that when the start switch 28 of the life detecting device 20 is turned on, the motor 21 will drive the elliptical eccentric 22 to rotate, wherein each time the elliptical eccentric 22 rotates, the long shaft 221 will drive the driving guide plate 23 at The first direction reciprocates once, and drives the dial block 232 and the switch button 14 to move between the first position 161 and the second position 162, that is, the life detecting device 20 has automatically switched the switch to the electronic device 10. 14 performs a toggle switching operation. At this time, the sensor 25 senses that the motor 21 is rotated once, which is equivalent to the switching button 14 being toggled once, and the counter 26 is used to accumulate the sensor 25 to induce the motor 21 to rotate. The number of times corresponds to the number of times the switch button 14 is toggled.

Compared with the prior art, the life detecting device of the present invention can automatically switch the switching key, the force of the dialing is more stable and average than the manual mode, and the recorder automatically records the number of toggle switching of the switching button.
