Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1-3, the device for testing the service life of the key panel includes a frame 1, a mounting base 2 disposed on the frame 1, a lifting base 3 disposed on the mounting base 2 and capable of lifting, a crank-link mechanism 7 disposed on the mounting base 2 and used for driving the lifting base 3 to lift, a guide mechanism disposed between the mounting base 2 and the lifting base 3, a tool 4 disposed on the frame 1 and used for placing the key panel, and a pressing member 5 disposed on the lifting base 3 and located above the tool 4.

Through the arrangement, when the crank connecting rod 7 mechanism drives the lifting seat 3 to do reciprocating lifting motion, the key panel can be intermittently pressed through the pressing piece 5, so that the pressure-bearing times of the key panel can be tested. The speed of the lifting seat 3 driven by the crank-connecting rod 7 mechanism to do reciprocating lifting motion can be adjusted, so that the pressure applied to the key panel by the pressing piece 5 can be adjusted, and the test of the pressure bearing pressure of the key panel is realized.

The crank connecting rod 7 mechanism comprises a rotary table which can rotate around the axis line direction of the crank connecting rod 7 mechanism and is arranged on the mounting base 2, a driving motor 6 for driving the rotary table to rotate, and a connecting rod 7 with the upper end and the lower end respectively rotatably connected to the end face of the rotary table and the lifting base 3. The axis of the turntable extends in the horizontal direction. The rotating center lines of the upper end and the lower end of the connecting rod 7 are parallel to each other and are parallel to the axis line of the turntable.

In this embodiment, the output shaft of the driving motor 6 extends in a vertical direction, the crank link 7 mechanism further includes a driving gear 9 coaxially connected to the top end of the output shaft, and the turntable is a bevel gear 10 engaged with the driving gear 9 through the left end face thereof (the left in fig. 3 is referred to herein as the left).

The upper end of the connecting rod 7 is rotatably connected to an eccentric position of a right end face (right in fig. 3) of the bevel gear 10. I.e., the center line of rotation of the upper end of the connecting rod 7 does not pass through the center of rotation of the bevel gear 10, to achieve eccentric rotation of the upper end of the connecting rod 7. When the lifting seat works, the driving motor 6 drives the driving shaft to rotate, the driving shaft drives the bevel gear 10 to rotate through the driving gear 9, and the bevel gear 10 drives the upper end of the connecting rod 7 to rotate, so that the upper end of the connecting rod 7 simultaneously carries out lifting motion, and the lifting seat 3 is driven to carry out reciprocating lifting motion.

Through setting up the radius of rotation of connecting rod 7 upper end relative carousel axial lead, can set up the stroke that lift seat 3 made reciprocating elevating movement as required, efficiency of software testing is higher relatively. The smaller the rotation radius is, the smaller the stroke of the lifting seat 3 in reciprocating lifting motion is; the larger the rotation radius is, the larger the stroke of the lifting seat 3 in reciprocating lifting motion is.

The device for testing the service life of the key panel further comprises a screw rod 8 which can rotate around the axis direction of the screw rod and is arranged on the frame 1, and a nut connecting seat (not shown in the figure) which is sleeved on the screw rod 8 and is fixedly connected with the lifting seat 3.
