Description

Technical Field

[0001] The utility model belongs to the technical field of button detection equipment, and particularly relates to a fatigue test equipment for button switches. Background Art

[0002] In industries such as electronics, machinery, and automobiles, button switches, as key components for human-machine interaction, their reliability and durability directly affect the overall performance of products and user experience. Therefore, conducting fatigue tests on button switches to evaluate their performance stability under long-term or multiple operations has become an important part of product design and quality control. However, traditional button switch fatigue test equipment often fails to meet the test requirements of batch, high efficiency, and reliability. In this regard, the patent document CN202119609U discloses a multi-station gravity impact simulation machine fatigue life test bench. This solution aims to improve test efficiency by setting multiple stations, with an impact head corresponding to each station above. Although this design can improve the test speed to a certain extent, there is no dedicated product fixing device on each station, which means that test samples cannot be directly placed, and customized fixing jigs need to be additionally equipped.

[0027] As Figures 1 to 5 shown, a push-button switch fatigue testing device includes;

[0028] A test bench 100;

[0029] A first clamping assembly 200, which is disposed on the test bench 100 and includes a plurality of first mounting holes 220 for fixing the push-button switch 700.

[0030] Impact device, which includes an impact assembly and a drive assembly 400 connected to each other. The impact assembly is movably disposed above the first clamping assembly 200, and includes a number of impact members 300 corresponding to and coaxial with the first mounting holes 220 one by one. The impact member 300 has a first moving position and a second moving position. The drive assembly 400 is disposed on the test bench 100 to drive the impact assembly to move between the first moving position and the second moving position. When the impact member 300 is in the first moving position, the impact member 300 abuts against the push button switch 700 in the first mounting hole 220. When the impact member 300 is in the second moving position, the impact member 300 is separated from the push button switch 700 in the first mounting hole 220. It realizes the batch fixation and testing of the push button switch 700, effectively improves the overall testing efficiency of the push button switch 700, and effectively ensures the consistency and accuracy of the testing by precisely controlling the position of the impact member 300.

[0031] As Figures 1 to 5 shown, in this embodiment, the test bench 100 is rectangular, and the first clamping assembly 200 and the impact device are both detachably disposed on the side of the test bench 100 facing away from the ground.

[0032] In this embodiment, the first clamping assembly 200 includes a number of first mounting holes 220 for fixing the push button switch 700, so as to ensure that multiple push button switches 700 can be stably subjected to fatigue testing, avoiding the need for additional customized fixing jigs.

[0033] In this embodiment, the first clamping assembly 200 includes a first mounting plate 210, which extends along the length direction of the test bench 100. A number of first mounting holes 220 are provided on the first mounting plate 210 and penetrate through the first mounting plate 210. The setting of the first mounting plate 210 enables the user to fix push button switches 700 of different models and specifications by replacing the first mounting plates 210 of different specifications, thereby improving the versatility of the testing equipment. The design that the first mounting holes 220 penetrate through the first mounting plate 210 facilitates the connection of the wiring terminals of the push button switch 700 to the switching power supply.

[0034] In this embodiment, the first mounting holes 220 are arranged in a straight line along the length direction of the first mounting plate 210, and there is a gap between adjacent two first mounting holes 220. On the one hand, it greatly facilitates the rapid positioning, loading and unloading of the push button switch 700 by the operator, significantly improving the efficiency of the preparation work before testing. On the other hand, it avoids interference between adjacent two push button switches 700; and each first mounting hole 220 is in an arch shape, and is provided with a notch 221 communicating with the outside, effectively simplifying the process of inserting and removing the push button switch 700.

[0035] In this embodiment, the first clamping assembly 200 further includes a support base 230 detachably provided on the test bench 100, and the first mounting plate 210 is detachably provided on the support base 230. While ensuring stable support for the first mounting plate 210, the first clamping assembly 200 is easy to replace and maintain, improving the flexibility and maintenance efficiency of the equipment.

[0036] In this embodiment, the support base 230 is detachably connected to the test bench 100 by bolts.

[0037] In this embodiment, the support base 230 is in the shape of a rectangular column, and there are two groups, symmetrically arranged at both ends of the first mounting plate 210, effectively ensuring the stable fixation of the first mounting plate 210. And a quick-release structure 240 is provided between the support base 230 and the first mounting plate 210 to form a detachable connection, realizing the quick assembly and disassembly of the first mounting plate 210 and the support base 230, greatly saving the time cost of equipment adjustment and maintenance.

[0038] In this embodiment, the quick-release structure 240 includes a fixing member 241 detachably provided on the support base 230, and a movable member 242 rotatably clamped on the first mounting plate 210. An activity groove 243 is provided in the fixing member 241, and the movable member 242 passes through the first mounting plate 210 and extends into the activity groove 243. And the movable member 242 has a first rotation position and a second rotation position. When the movable member 242 is in the first rotation position, the fixing member 241 and the movable member 242 are in a locked state. When the movable member 242 is in the second rotation position, the fixing member 241 and the movable member 242 are in an unlocked state. Through the design and cooperation of the fixing member 241 and the movable member 242, the operator only needs to perform a simple rotation operation to complete locking and unlocking, effectively improving work efficiency.

A second clamping groove 211 for accommodating the movable member 242 is provided on the first mounting plate 210, and the movable member 242 is rotatably clamped in the second clamping groove 211. A clamping post 246 is provided on the movable member 242. When the movable member 242 is in the first rotation position, the clamping post 246 is clamped in the circular through hole 244, so that the fixing member 241 and the movable member 242 form a locked state. When the movable member 242 is in the second rotation position, the clamping post 246 is aligned with the strip-shaped hole 245 and can be sequentially drawn out from the circular through hole 244 and the strip-shaped hole 245, so that the fixing member 241 and the movable member 242 form an unlocked state.

[0040] Preferably, in this embodiment, the clamping post 246 is adapted to the size of the strip-shaped hole 245.

[0041] To perform a fatigue test on the push-button switch 700, in this embodiment, an impact device for repeatedly impacting the push-button switch 700 is provided. The impact device includes an impact assembly and a driving assembly 400 for driving the movement of the impact assembly. The impact assembly includes a plurality of impact members 300 disposed in the second mounting holes 530 and corresponding to and coaxial with the first mounting holes 220 one by one. The impact member 300 has a first moving position and a second moving position. When the impact member 300 is in the first moving position, the impact member 300 abuts against the push-button switch 700 in the first mounting hole 220 to simulate the pressing state when the push-button switch 700 is working. When the impact member 300 is in the second moving position, the impact member 300 is separated from the push-button switch 700 in the first mounting hole 220 to simulate the relaxed state of the push-button switch 700, so as to repeatedly press the push-button switch 700 subsequently.

[0042] In this embodiment, the first moving position refers to the position where the impact member 300 can contact the push-button switch 700 and perform pressing, and the second moving position refers to the position where the impact member 300 is separated from the push-button switch 700 and the push-button switch 700 can return to the non-pressed state.

[0043] In this embodiment, the impact assembly is connected to the driving assembly 400 through a second clamping assembly 500. The second clamping assembly 500 includes a fixing plate 510 connected to the output end of the driving assembly 400, and a second mounting plate 520 connected to the fixing plate 510 and parallel to the first mounting plate 210. A plurality of second mounting holes 530 corresponding to and coaxial with the first mounting holes 220 one by one are provided on the second mounting plate 520, and the impact members 300 are detachably disposed in the second mounting holes 530. This not only ensures the stable connection between the impact assembly and the driving assembly 400, but also realizes the precise positioning of a plurality of impact members 300 through the second mounting holes 530, ensuring the accuracy of the test.

[0044] In this embodiment, the second mounting plate 520 is rectangular, and adjustment slots 540 corresponding to and communicating with a plurality of second mounting holes 530 one by one are provided thereon.

When the adjusting member 550 rotates, the opening degree of the adjustment slots 540 can be adjusted, and the opening degree of the second mounting holes 530 changes synchronously with the opening degree of the adjustment slots 540. On the one hand, it can realize the assembly of impact members 300 of different specifications, improving the versatility of the test equipment. On the other hand, it enables the operator to adjust the installation height of the impact members 300 as needed, thereby realizing the adjustment of the impact depth, enhancing the adaptability of the test equipment and the flexibility of the test.

[0045] Preferably, in this embodiment, the adjusting member 550 is threadedly connected to the second mounting plate 520 .

[0046] In this embodiment, the driving assembly 400 includes a driving member 410 detachably disposed on the test bench 100, and a crank connecting rod structure 420 having one end connected to the output end of the driving member 410 and the other end connected to the fixed plate 510. When the driving member 410 is started, the crank connecting rod structure 420 drives the fixed plate 510 to move up and down, thereby realizing an automated impact test. The combination of the driving member 410 and the crank connecting rod structure 420 provides a stable power source for the impact member 300, ensuring the movement stability of the impact member 300 and the precise control of the impact force.

[0047] Preferably, in this embodiment, the driving assembly 400 is further provided with a first support plate 430, which is detachably provided on the test bench 100 and extends in a direction perpendicular to the test bench 100, and the driving member 410 and the crank-connecting rod structure 420 are both detachably installed on one end of the first support plate 430 close to the fixed plate 510, which effectively saves the length of the crank-connecting rod structure 420 and expands the range of motion of the impact member 300. Preferably, the driving member 410 is a motor.

[0048] In this embodiment, a guide assembly 600 is also provided, and the guide assembly 600 includes a guide rail 610 disposed on the test bench 100 and perpendicular to the second mounting plate 520, and a slider 620 connected to the fixed plate 510 on one side and slidably connected to the guide rail 610 on the other side, and the guide rail 610 extends along the movement direction of the impact member 300.
