This is related to the quality of the product, so the testing work is very important.电子 Currently, electronic products that are active in the market, such as mobile phones, notebook computers, and handheld game consoles, often use a structure with a body and a cover. Since the cover body often needs to move relative to the body to open and close the electronic product, some of the structures on the cover body may be damaged due to long-term use or wear, thereby affecting the service life of the cover body. For example, the one-hand machine shown in Fig. 2 has a lock 12 at one end and a two-knife stress loss structure tab 142 at the other end. The roots 14 of the two tabs 142 are joined and attached to the mobile phone cover 1 through ❾=14. The lock 12 will be broken due to the long-term reversed engagement of the θ 'tb 142 due to long-term shear stress. Yu Yu' Before the product leaves the factory, it is necessary to determine the mechanical durability of the lock 12 of the mobile phone cover and the tongue = 2 to determine the service life of the mobile phone cover i.

When the cam 53 rotates one cycle counterclockwise, and the mobile phone cover 1 is not damaged, the test mechanism 12 200944794 device group will perform the following actions: When the arc segment abj of the cam 53 is moved, the oscillating lever 44 is only in contact with the cam 53 and the kines 42 is deformed. The phone cover 1 is against the pressure sensor.

Please refer to the circle 7, when the roller 444 reaches the point C of the cam 53 At this time, the slider 314 is pushed to the left by the swing lever 44 until the lock tongue 312 is disengaged from the latch 12 of the mobile phone cover i, and the compression spring 33 of the lock engagement simulation device is compressed. Thus, the tongue 142 of the mobile phone cover is The internal stress generated by the pressing body 384 of the shear stress structure and the support body 382 is released, so that the rotation of the tongue 142 relative to the support body 382 drives the entire mobile phone cover 1 to rotate, so that the mobile phone cover The right end of i is slightly tilted, and the pressure generated by the mobile phone 盍1 on the Lili sensor 66 is released (actually, the mobile phone cover 1 still exerts pressure on the pressure sensor 66 due to its gravity, but through the adjustment of the pressure sensor The sensitivity of 66 'can eliminate the effect of this gravity." And then 'when the swinging rod 44 rolls When the 444 continues to roll on the arc segment CD of the cam 53, the lock-lock simulation device and the phone cover 1 remain in the current state. (3) When the roller 444 of the swing lever 44 rolls on the arc segment DE of the cam 53 The torsion spring 42 between the rocker 44 and the rocker bracket 40 is resilient 13 200944794 'recovery' such that the second swing arm of the swing lever 44 moves to the right and disengages from the first extension 37 of the block 314, The slider 314 slides to the right to the initial position by the elastic restoring force of the phthalocyanine. At the same time, the first swing arm 1 of the swing lever 44 moves downward, the roller 443 of the first swing arm 441 contacts and presses the mobile phone cover 1, so that the mobile phone cover 1 again exerts pressure on the pressure sensing device 66, and makes the mobile phone The lock of the cover 1 and the lock tongue 312 of the slider 314 of the imitation money are matched, and the tongue 142 of the mobile phone cover i is again subjected to the internal stress generated by the shear stress simulation structure. Then, when the roller 444 of the pendulum 44 continues to roll on the arc segment EF of the cam 53, the latch snaps the snap button and the phone cover ... to maintain the current state. (4) When the roller 444 of the swing lever 44 rolls on the arc segment FA of the cam 53, the second swing arm 442 is pushed by the cam 53 and moved to the left, and the first swing arm 441 of the swing lever 44 moves upward. The roller (4) is disengaged from the cover of the mobile phone until the roller 444 of the swing lever 44 will roll to the arc segment AB of the cam 53, so that the test mechanism device group is in the state described in the above (1). In summary, during one rotation period of the cam 53, and the mobile phone cover 1 is not damaged, the pressure sensor 66 only rotates when the roller tip of the swing lever 44 rolls on the arc segment CD of the cam 53. Will lose pressure once. If the lock 12 or the tongue 142 of the mobile phone cover fails due to damage during a certain rotation period of the cam 53, the lock U will automatically disengage from the lock tongue 312 or the tongue 142 and automatically release it due to failure. The stress, as shown in Fig. 9 and with reference to Fig. 6, is that when the swinging rod (four) roller object passes through the cam, the arc segment FA rolls to the arc segment heart temple, and the mobile phones only have insufficient gravity to make the force sensor 66 Feeling repeated, the number of repeated sensors will also lose 200944794 - pressure. Thus, one of the cams 53 will be dusted twice. Rotate the peripheral phase, the pressure sensor % and refer to the _U, use the mechanical life test device of the present invention to measure the 5th day T' assuming the 手机 of the mobile phone cover 1 and the mechanical life of the K-lock 12 or the tongue W When it is used N times, it is turned on: the 丨诂 ci 4* ^ test device, the control circuit starts to work and the motor 51 rotates ' and the two counters 61, 62 are cleared. The φ can be adjusted by the speed adjustment knob 50 to adjust the wire of the horse far 51, and the Μ is rotated periodically, so that the test can be performed periodically. The (four) circuit is pure one: the data sent by the decimal device 62, and the data is synchronously compared, if the number (four) 'the control circuit controls the motor 51 to run α, if the counts of the two counters 61, 62 are not the same, it is assumed that When the cam 53 is rotated to the third turn, the latch 12 or the tab "a of the mobile phone cover" is disabled due to the damage. At this time, the count of the second counter 62 recording the number of times the photoelectric switch 64 is turned off is N, and the sense of pressure is recorded. The count of the first counter counter 61 of the detector % of the number of out of pressure is N+1, and the control circuit controls the motor 51 to stop running. Then the operator knows that the latch 12 or the bump of the mobile phone cover is based on the count of the second counter 62. The mechanical life of the tongue 142 can be used, whereby the service life of the mobile phone cover 1 can be known. In addition, in general, the buckle 12 of the mobile phone cover 1 is more susceptible to wear and damage than the tongue 142. The mechanical life testing device of the present invention is often only used to test the service life of the latch 12. In other embodiments, the near rest angle arc segment EF, the intermediate rest angle arc segment AB, and the far rest angle arc segment on the cam 53 Cd can 15 200944794 - was This is because the 'rest angle arc segments Ep, ab, CD are only when the swing lever 44 is engaged with the cam 53, and the swing lever 44 is in its return stroke (corresponding to the convex, 53 return arc segment DE) And the first lift (corresponding to the first lift arc segment FA of the cam 53), the first lift and the second lift (corresponding to the second lift arc segment BC of the cam 53) @, second A buffering process is provided between the lift and the return. In summary, the invention complies with the requirements of the invention patent, and the patent is filed according to law. The above is only a preferred embodiment of the present invention, and is familiar with the skill of the present invention.
