Description

Technical Field

[0001] This utility model relates to the field of button life testing technology, specifically to an automatic return-type button life testing fixture. Background Technology

[0002] The automatic reset button life test fixture is a special testing device designed to test the lifespan and reliability of various buttons. The button press head has an autonomous reset function, which can simulate the actual use scenario to continuously press the button repeatedly. At the same time, the matching counting and force monitoring modules record the test data, and finally accurately judge the mechanical durability and electrical performance stability of the button.

[0003] The pressure head of the existing automatic return-type button life testing equipment has a fixed position, and the distance between it and the button is inconvenient to adjust. When testing buttons of different heights, the height of the button placement stage needs to be adjusted, which is cumbersome and can easily affect the stability of the placement stage, thus affecting the test accuracy.

[0004] Therefore, an automatic reset button life test fixture is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic reset button life testing fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic return-type button life testing fixture, comprising a testing unit and a positioning unit. The test unit is placed on the top surface of the support base. The test unit includes a test component and an adjustment component. The test component is used to test the lifespan of the buttons, and the adjustment component is used to test the adaptability of buttons with different travel heights. The positioning unit is placed inside the test unit and extends to the outside of the test unit. The positioning unit is used to position and clamp the button below the test unit. Under the restriction of the positioning unit, the button can be stably clamped. Under the restriction of the test unit, the life of the clamped button can be tested. The distance between the test component and the button can be adaptively adjusted according to the button travel height.

[0007] Preferably, the test assembly includes a frame, a motor connected to the side wall of the frame, a rotating rod connected to the output end of the motor, an elliptical disk connected to the end of the rotating rod, a first limiting rod connected to the top inner surface of the frame, a first magnetic ring connected to the end of the first limiting rod, a frame body slidably disposed on the outer wall of the first limiting rod, and a second magnetic ring connected to the inner side of the frame body.

[0008] Preferably, the adjustment component includes a support plate connected to the end of the frame, a first screw is sleeved inside the support plate, a counting pressure head is rotatably connected to the end of the first screw, and a second limiting rod is connected to the top surface of the counting pressure head.

[0009] Preferably, the outer wall of the elliptical disk is slidably disposed with respect to the top surface of the frame, and the inner side of the elliptical disk is slidably disposed with respect to the side wall of the frame. Under these constraints, the elliptical disk can stably slide and compress against the top surface of the frame.

[0010] Preferably, the second magnetic ring and the first magnetic ring are magnetically repelled, and the interior of the second magnetic ring is slidably disposed with respect to the outer wall of the first limiting rod. Under the restriction of magnetic repulsion, an automatic return-type pressing test can be achieved.

[0011] Preferably, the positioning unit includes a telescopic rod connected to the top surface of the support seat, and a clamping plate is connected to the end of the telescopic rod; A side plate is slidably disposed inside the clamping plate, and a second screw is rotatably connected to the side wall of the side plate. An inclined block is connected to the side of the side plate away from the second screw.

[0012] Preferably, the outer wall of the second screw is fitted inside the upright frame, and a disc is provided at the end of the second screw away from the side plate. Under the restriction of the disc, it is convenient for the operator to rotate the second screw to push the side plate.

[0013] Preferably, one side of the inclined surface of the inclined block faces the top surface of the support seat, and the inclined block is placed in the middle of the side plate. Under the restriction of the inclined block, a downward clamping pressure can be applied to the button.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, after the button is fixed to the support base by the positioning unit, the motor drives the rotating rod and the elliptical disk to rotate. The elliptical disk squeezes the frame, causing the counting pressure head to press the button downwards. When the elliptical disk resets, the first magnetic ring and the second magnetic ring repel each other, pushing the frame and the pressure head to automatically return to their positions. The counting pressure head synchronously records the number of presses. By rotating the first screw, the distance between the pressure head and the button can be adjusted to adapt to button testing with different stroke heights. 2. In this utility model, after the button is placed on the support seat, the telescopic rod pushes the clamping plate to initially clamp the button, and the rotation of the second screw drives the side plate to move in opposite directions to achieve all-round clamping of the button; the inclined block applies downward pressure through the inclined surface to prevent the button from moving upward due to vibration during testing and to ensure test stability.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1: Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides an automatic return-type button life testing fixture, including a testing unit 1 and a positioning unit 2. Test unit 1 is placed on the top surface of support 3. Test unit 1 includes a test component and an adjustment component. The test component is used to test the lifespan of the key, and the adjustment component is used to test the adaptability of the key to different travel heights. Positioning unit 2 is placed inside test unit 1 and extends to the outside of test unit 1. Positioning unit 2 is used to position and clamp the button below test unit 1.

[0024] Under the constraints of positioning unit 2, the button can be stably clamped. Under the constraints of testing unit 1, the lifespan of the clamped button can be tested, and the distance between the testing components and the button can be adaptively adjusted according to the button travel height.

[0025] Example 2: Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as detailed below: The test assembly includes a frame 11, a motor 12 connected to the side wall of the frame 11, a rotating rod 13 connected to the output end of the motor 12, an elliptical disk 14 connected to the end of the rotating rod 13, a first limiting rod 15 connected to the inner top surface of the frame 11, a first magnetic ring 16 connected to the end of the first limiting rod 15, a frame 17 slidably disposed on the outer wall of the first limiting rod 15, and a second magnetic ring 18 connected to the inner side of the frame 17. The adjustment assembly includes a support plate 19 connected to the end of the frame 17. A first screw 110 is sleeved inside the support plate 19. A counting head 111 is rotatably connected to the end of the first screw 110. A second limiting rod 112 is connected to the top surface of the counting head 111.

[0026] The outer wall of the elliptical disk 14 is slidably disposed with the top surface of the frame 17, and the inner side of the elliptical disk 14 is slidably disposed with the side wall of the frame 17. Under its constraint, the elliptical disk 14 can stably slide and squeeze the top surface of the frame 17.

[0027] The second magnetic ring 18 and the first magnetic ring 16 are magnetically repelled. The interior of the second magnetic ring 18 is slidably disposed with the outer wall of the first limiting rod 15. Under the restriction of magnetic repulsion, an automatic return-type pressing test can be realized.

[0028] During button life testing, the button is clamped to the top surface of the support base 3 via the positioning unit 2. The motor 12 is then started, and the rotating rod 13, fixedly mounted at its output end, rotates accordingly. The rotating rod 13 drives the elliptical disk 14 to rotate as well. When the elliptical disk 14 slides and presses against the top surface of the frame 17, it causes the frame 17 to slide downwards along the outer wall of the first limiting rod 15. The frame 17 then drives the support plate 19, the first screw 110, and the counting pressure head 111 to move downwards, pressing the button. When the elliptical disk 14 returns to its original position and rotates, it no longer slides and presses against the top surface of the frame 17. Under the magnetic repulsion constraint of the first magnetic ring 16 and the second magnetic ring 18, the button life can be tested. The frame 17 is pushed back up from the top, and the frame 17 drives the first screw 110, the counting head 111, and the second limiting rod 112 to move upward through the support plate 19, achieving an automatic return effect. Under the constraint of the counting head 111, the number of button presses can be recorded. When the button travel height is different, the first screw 110 is rotated. Because the outer wall of the second limiting rod 112, which is fixedly installed on the top surface of the counting head 111, is slidably set inside the support plate 19, the rotating first screw 110 can push the counting head 111 under its constraint, so as to adaptively adjust the distance between the counting head 111 and the button. This structure can realize automatic return-type pressing test and can adaptively adjust the pressing of buttons with different pressing travel heights.

[0029] Example 3: Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The positioning unit 2 includes a telescopic rod 21 connected to the top surface of the support base 3, and a clamping plate 22 is connected to the end of the telescopic rod 21; A side plate 24 is slidably disposed inside the clamping plate 22. A second screw 23 is rotatably connected to the side wall of the side plate 24. An inclined block 25 is connected to the side of the side plate 24 away from the second screw 23.

[0030] The second screw 23 is sleeved inside the frame 11 on its outer wall. The end of the second screw 23 away from the side plate 24 is provided with a disc. Under the restriction of the disc, it is easy for the operator to rotate the second screw 23 to push the side plate 24.

[0031] The inclined block 25 has one side facing the top surface of the support seat 3, and the inclined block 25 is placed in the middle of the side plate 24. Under the restriction of the inclined block 25, downward clamping pressure can be applied to the button.

[0032] When testing the button's lifespan, it is placed on the top surface of the support base 3. The telescopic rod 21 is then activated, pushing the clamping plates 22. The two clamping plates 22 initially clamp the button. Then, the second screw 23 is rotated. Because the outer wall of the second screw 23 is threaded into the inside of the frame 11, and the outer wall of the side plate 24 slides within the clamping plates 22, the rotating second screw 23 pushes the side plate 24, which is rotatably connected to its end. The two side plates 24 move in opposite directions, clamping the other two sides of the button. Under the constraint of the inclined surface of the wedge block 25, downward pressure is applied to the press base, preventing the button from moving upwards due to vibration during pressing. This structure can clamp the button from all directions and apply downward pressure to ensure stable testing.

[0033] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The counting mechanism in the counting head is the existing known technology, so its structure has not been fully described.

[0034] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
