Service life detecting device for switching key

Abstract

The invention discloses a service life detecting device for a switching key. The switching key moves between a first position and a second position in a first direction. The service life detecting device comprises a motor, an elliptical eccentric wheel and a drive guide plate, wherein the motor is provided with an output shaft; the elliptical eccentric wheel is combined with the output shaft, andis provided with a long axis and a short axis; the drive guide plate is provided with a guide groove and a toggle block; the guide groove is matched with the elliptical eccentric wheel; and the toggleblock is combined with the switching key. When the motor drives the elliptical eccentric wheel to rotate, the long axis drives the drive guide plate to reciprocate in the first direction, and drivesthe toggle block and the switch key to move between the first position and the second position. The service life detecting device can automatically perform toggle switching of the switching key, has more stable and average toggle force compared with manual toggle force, and is more accurate than brain memory by adopting a recorder to automatically record the toggle switching times of the switchingkey.

Description

technical field [0001] The invention relates to a life detection device of a switch key, in particular to a life detection device which can automatically switch a switch key and calculate the switching times. Background technique [0002] The switch key is a common component in the electronic device. The switch key is mainly used to change the power supply state or set the electronic device in different functional states by changing its position. [0003] see figure 1 A schematic diagram of an electronic device 10 in the prior art includes a main body 12 and a switch key 14 . The surface of the main body 12 is provided with a sliding groove 16, and the sliding groove 16 has a first position 161 and a second position 162, wherein the switching key 14 can be operated between the first position 161 and the second position 162 of the sliding groove 16. Moving back and forth, the electronic device 10 sets the electronic device 10 in different states by changing the position of ...

Problems solved by technology

However, when the life test of the switching key 14 is performed manually, in addition to the uncontrollable force of the switching, the tester must also use the brain to remember the number of times the switching key 14 is pressed. The tester's brain is easy to remember wrongly due to fatigue. Greatly affect the accuracy of the life test of the switch key 14
