Switching rotation testing device

Abstract

The invention relates to a switching rotation testing device which comprises a base, a first frame, a second frame, a first driving device and a second driving device, wherein the bottom end of the first frame is pivoted with the base by a first pivot which has a first pivot direction; the second frame is pivoted with the first frame by a second pivot which has a second pivot direction perpendicular to the first pivot direction; the first driving device can drive the first frame to rotate around the first pivot as a center; the second driving device comprises a driving motor and a belt device; the driving motor is arranged on the first frame and is adjacent to the first pivot; the belt device is connected with the second frame; the driving motor is provided with a driving shaft which is connected with the belt device for driving the belt device; and the belt device drives the second frame to rotate around the second pivot as a center.

Description

technical field [0001] The invention relates to an opening and closing rotation testing device, in particular to an opening and closing rotation testing device which can shorten the force arm and reduce the weight, thereby saving power and production cost. Background technique [0002] Different types of electronic devices are currently on the market, such as tablet (Tablet) computers, computers with tablet functions, notebook computers, mobile communication devices, etc., most of which have a flip-up cover, which is usually provided with a screen. For the convenience of viewing the screen, the flip-top cover is more rotatable. For this type of opening and closing rotating screen, the manufacturer must carry out the opening and closing rotation test to test the durability of the pivot, so as to provide the manufacturer with relevant information on the service life and durability of the pivot of the electronic device, so as to benefit the manufacturer Improve structural desi...

Problems solved by technology

[0003] see figure 1 and figure 2 , which shows a known opening and closing rotation testing device 10, the opening and closing rotation testing device 10 has an outer frame 11, and two symmetrical inner frames 12 are pivotally arranged inside the outer frame 11, and the top of the outer frame 11 corresponds to The positions of the inner frame 12 are respectively provided with a motor 13, and the outer frame 11 is driven by a driving device 14 to rotate around the outer pivot 15, and the inner frame 12 is driven by the motor 13 to rotate around the inner pivot 16. The axis directions of the inner pivot 16 and the outer pivot 15 are perpendicular to each other. Since the motor 13 is arranged on the top of the outer frame 11, the weight is concentrated on the top of the outer frame 11. When the outer frame 11 is overturned, the motor 13 The force arm distance to the outer pivot 15 is extremely long, and the driving device 14 must output extremely high power, so the service life of the driving device 14 is shortened. In addition, two motors 13 respectively drive an inner frame 12 to rotate, and the cost is also low. very high
