technical field

The invention relates to a test device, in particular to a test device for testing the reliability and life of keys.

Background technique

With the advancement of science and technology, various electronic products are constantly being introduced. Before each new product is launched, it needs to go through a series of reliability tests (reliability test) and life test (life test) to ensure the quality of the product. Among them, the buttons of the electronic product are used to perform various electrical functions after the user presses them. Therefore, in the reliability test of the button, repeated pressing must be performed to predict whether the button will maintain a certain quality after a long time of use.

Please refer to FIG. 1A-FIG. 1C , which illustrate a schematic diagram of the operation of a traditional testing device 900 . The traditional testing device 900 includes a slider 910 , a thimble 920 and a spring 930 . The spring 930 is disposed between the thimble 920 and the slider 910 . The thimble 920 corresponds to a key 800 . First, as shown in FIG. 1A , the slider 910 moves toward the button 800 with a thrust F910 .

Next, please refer to FIG. 1B . The slider 910 pushes the spring 930 and the thimble 920 , so that the thimble 920 presses the key 800 with a pressing force F920 and moves the key 800 by a pressing stroke D920 . Wherein, the spring 930 is used to provide a buffer force between the slider 910 and the thimble 920 .

Then, as shown in FIG. 1C , the slider 920 returns to its original position by the restoring force F930 of the spring 930 . As mentioned above, the testing device 900 repeatedly and continuously presses the button 800 in the above actions to perform the reliability test of the button 800 .

However, the conventional testing device 900 has the following problems that have been insurmountable for a long time:

First, the pressing stroke is unstable: in each test process of the traditional test device 900, due to too many variables of the slider 910 and the spring 930, it is impossible to ensure that the thimble 920 presses the button 800, and the button 800 moves for a fixed time. The pressing stroke D920.

Second, the pressing force is inaccurate: during the test, factors such as the thrust F910 and the spring 930 may also cause the pressing force F920 to not meet the original set value.

Therefore, how to develop a test device to solve the above-mentioned problems is an important research and development direction at present.

first embodiment

Please refer to FIG. 2 and FIG. 3A , FIG. 2 shows a schematic view of the appearance of the test device 100 according to a preferred embodiment of the present invention, and FIG. 3A shows a cross-sectional view of the test device 100 according to FIG. 2 . As shown in FIG. 2 , the test device 100 is used to test the reliability or lifespan of at least one button 700 . The testing device 100 includes at least one pressing mechanism 110 and at least one pressing mechanism 120 . As shown in FIG. 3A , the pressing mechanism 110 includes a first pusher 111 , a second pusher 112 , a first elastic body 113 and an adjustment element 114 . The first elastic body 113 is disposed between the first pusher 111 and the second pusher 112 , and the first elastic body 113 in this embodiment is described by taking a spring as an example. The pressing mechanism 120 includes a striker 121 disposed between the pressing mechanism 110 and the button 700 .

Wherein, the testing device 100 further includes a support frame 140 . The pressing mechanism 110 and the pressing mechanism 120 are disposed on the supporting frame 140 such that the pressing mechanism 110 , the pressing mechanism 120 and the button 700 are arranged along a straight line L. As shown in FIG. The pressing mechanism 110 , the pressing mechanism 120 and the button 700 move back and forth along the straight line L. As shown in FIG.

Please refer to FIGS. 3A to 3D at the same time. FIGS. 3B to 3D illustrate the operation process of the test device 100 in FIG. 3A . As shown in FIG. 3B , a pushing force F110 pushes the first pushing member 111 and the second pushing member 112 to move toward the pressing mechanism 120 . When the first pusher 110 abuts against the striker 121 , the first pusher 111 stops moving.

Next, please refer to FIG. 3C. The first pusher 111 and the second pusher 112 are relatively movable. Therefore, when the first pusher 111 abuts against the striker 121 , the second pusher 112 can still move toward the pressing mechanism 120 . The thrust F110 continues to push the second pusher 112 until the thrust F110 stops, so that the first pusher 111 and the second pusher 112 move a pressing distance D113 with each other. At this time, the first pusher 111 and the second pusher 112 compress the first elastic body 113 , so that the compressed first elastic body 113 generates a pressing force F113 . The pressing mechanism 120 pushes the striker 121 to move toward the button 800 within a pressing stroke D121 with the pressing force F113 . At the same time, the button 800 also moves a pressing stroke D121

Next, in FIG. 3D , the second elastic body 123 of this embodiment is a spring. The second elastic body 123 is disposed between the fixing member 122 and the striker 121 . When the striker 121 moves toward the key 700 , the second elastic body 123 is compressed to generate a restoring force F123 on the striker 121 . When the first pusher 111 and the second pusher 112 return upward to their original positions, the striker 121 returns to its original position by the restoring force F123 . Thus, the striker 121 can move back and forth within the pressing stroke D121.

Wherein, during the above-mentioned movement process, the pressing distance D113 can be finely adjusted by the adjusting element 114 so that the pressing mechanism 110 can provide precise pressing force F113. And each time the pressing mechanism 110 pushes the striker 121 , the striker 121 moves within a fixed pressing stroke D121 .

As shown in FIG. 3A , the pressing mechanism 120 of this embodiment further includes a fixing part 122 and a second elastic body 123 . The striker 121 has a limiting protrusion 121a and a needle-shaped body 121b. The fixing member 122 has a receiving groove 122a and a through hole 122b. The accommodating groove 122a is used for accommodating the second elastic body 123, and the through hole 122b is disposed at the bottom of the accommodating groove 122a. The needle-shaped body 121b passes through the through hole 122b of the fixing member 122 , but the limiting protrusion 121a cannot pass through the fixing member 122 . That is to say, no matter how much the pressing force F113 of the pressing mechanism 110 pushes the striker 121 , the limit protrusion 121 a limits the movement of the striker 121 toward the button 700 within a fixed pressing stroke D121 (the pressing stroke D121 is shown in FIG. 3C ).

In addition, as shown in FIG. 3A , the pressing mechanism 110 further includes a pneumatic cylinder 115 and a pneumatic rod 116 . The pneumatic rod 116 has a first end 116a and a second end 116b. The first end 116 a is movably inserted into the pneumatic cylinder 115 , and the second end 116 b is coupled to the second pusher 112 and the adjustment element 114 . The adjustment element 114 is used for fine-tuning the position of the second pusher 112 coupled to the pneumatic rod 116 to change the extrusion distance D113 (the extrusion distance D113 is shown in FIG. 3C ). Wherein, the second end 116b of the pneumatic rod 116 has a threaded surface 116c, and the adjusting element 114 and the second pushing member 112 are screwed to the threaded surface 116c. When the position where the second pusher 112 is screwed to the pneumatic rod 116 changes, the extrusion distance D113 of the mutual movement of the first pusher 111 and the second pusher 112 also changes accordingly (the extrusion distance D113 is shown in FIG. 3C ). By changing the pressing distance D113, the pressing force F113 also changes accordingly. The relationship between the position where the second pusher 112 is screwed to the pneumatic rod 116 , the extrusion distance D113 and the pressing force F113 is described below by taking FIGS. 4A-4C as an example.

Please refer to FIGS. 4A to 4D , which illustrate the operation diagrams of the test device 100 in FIG. 3A after being fine-tuned by the adjustment element 114 . As shown in FIG. 4A , when the adjustment member 114 is moved downward, the position where the second pusher 112 is screwed to the pneumatic rod 116 is adjusted downward. Therefore, the second pusher 112 and the first pusher 111 are farther away from the pneumatic cylinder 115 . In other words, compared to FIG. 3A , the first pusher 111 in FIG. 4A is closer to the striker 121 .

Next, as shown in FIG. 4B , the thrust F110 moves the first pusher 111 and the second pusher 112 toward the pressing mechanism 120 .

Then, as shown in FIG. 4C , when the first pusher 111 abuts against the striker 121 , the second pusher 112 can still move toward the pressing mechanism 120 . The first pusher 111 and the second pusher 112 are moved to each other by a pressing distance D213.

Compared with FIG. 3C and FIG. 4C , the pneumatic cylinder 115 pushes the first pusher 111 and the second pusher 112 for a certain distance with equal thrust F110 . In FIG. 4C , since the first pusher 111 is closer to the striker 121 , when the second pusher 121 moves toward the key 700 , the first pusher 111 collides with the striker 121 earlier. The pressing distance D213 that makes the first pushing member 111 and the second pushing member 112 in FIG. 4C move mutually is greater than the pressing distance D113 in FIG. 3C . At the same time, the compressed first elastic body 113 generates a pressing force F213.

Wherein, the pushing distances D113 and D213 experienced by the first elastic body 113 are positively correlated with the pressing forces F113 and F213 . That is to say, the greater the pressing distance that the first elastic body 111 is subjected to, the greater the pressing force generated. Compared with FIG. 4C and FIG. 3C , the pressing distance D213 in FIG. 4C is larger, so a larger pressing force F213 can be generated. As mentioned above, the position where the second pusher 112 is screwed to the pneumatic rod 116 can be adjusted through the adjustment element 114 , thereby adjusting the extrusion distance D213 and the pressing force F213 .

Next, as shown in FIG. 4D , when the first pusher 111 and the second pusher 112 return upward to their original positions, the striker 121 returns to its original position by the restoring force F123 .

As mentioned above, if the user wants to increase the pressing force F113, the adjustment element 114 can be adjusted downward. On the contrary, if it is desired to reduce the pressing force F113, the adjustment element 114 can be adjusted upward. And by measuring the precise pressing force F113 through a thrust meter, the size of the pressing force F113 can be precisely controlled.

Wherein, the elastic coefficient of the first elastic body 113 is much larger than that of the second elastic body 123 , so that the pressing force F113 or F213 generated by the first elastic body 113 is sufficient to offset the restoring force F123 generated by the second elastic body 123 .

second embodiment

The difference between the test device 200 of this embodiment and the test device 100 of the first embodiment lies in the number of the pressing mechanism 110 and the pressing mechanism 120 , and the rest of the similarities will not be repeated here. Please refer to FIG. 5 , which shows a schematic diagram of a test device 200 according to this embodiment. In this embodiment, the testing device 200 includes several pressing mechanisms 110 and several pressing mechanisms 120 . Each pressing mechanism 110 and each pressing mechanism 120 correspond to each other, so as to respectively test the reliability or lifespan of several keys 600 . The pressing mechanisms 110 and the pressing mechanisms 120 are arranged in-line.

As long as the lengths of the striker 121 of each pressing mechanism 120 are equal, each striker 121 is restricted by the fixing member 122 , so that each striker 121 moves within the same pressing stroke D121 . Therefore, the test performed by each key 600 will be more accurate.

In addition, even if the thrust F110 of each pneumatic cylinder 115 has a certain degree of error, the user only needs to adjust the extrusion distance D113 with each adjustment element 114 to obtain an equal pressing force F113 .

In this embodiment, although the pressing mechanisms 110 and the pressing mechanisms 120 are arranged in-line as an example for illustration. However, the arrangement is not limited thereto, and the pressing mechanisms and the pressing mechanisms can also be arranged in a matrix according to the arrangement of the keys. As long as the pressing mechanism and the pressing mechanism achieve the fixed stroke of pressing the button with a fixed pressing force, it does not depart from the technical field of the present invention.

The test device disclosed in the above embodiments of the present invention utilizes the structural design of the pressure applying mechanism and the pressing mechanism, so that the test device has at least the following advantages:

First, the fixed pressing stroke: the pressing mechanism disclosed in the above-mentioned embodiment uses a fixing member to limit the striker so that the striker moves within the fixed stroke. Therefore, the depth to which the key is pressed by the striker can be fixed.

Second, the fixed pressing force: the pressing mechanism disclosed in the above embodiment properly fine-tunes the position of the second pusher screwed to the pneumatic rod through the adjustment element, so as to adjust the compression distance of the first elastic body and obtain precise pressing force .

Thirdly, test accuracy is greatly improved: as mentioned above, the test device can obtain precise pressing force, and the key system can move within a fixed pressing stroke. Therefore, the accuracy of the test results is greatly improved.

In summary, although the present invention has been disclosed in conjunction with the above preferred embodiments, they are not intended to limit the present invention. Those skilled in the art of the present invention can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be defined by the appended claims.
