Description

Technical Field

[0001] The invention mainly relates to the technical field of hidden switch life testing, and in particular to a device for testing the opening and closing life of a hidden switch. Background Art

[0002] Hidden switches are switches that are not directly exposed to the outside or not easily seen by users. They are usually installed inside the equipment or in an inconspicuous location to control the on and off of the circuit or a certain function of the equipment. The application scenarios of hidden switches mainly include smart homes, precision instruments, safety equipment and decorative switches. Although hidden switches increase the beauty and safety of the equipment, the design needs to consider how to facilitate users to quickly find and operate these switches when needed, as well as how to perform effective maintenance and testing.

[0003] After the hidden switch is processed into a product, the service life of the switch needs to be tested. The test results can provide feedback for product design and help manufacturers improve the design of the switch to make it more durable or adapt to specific application environments. By understanding the service life of the switch, preventive replacement or maintenance can be performed before the switch fails to avoid losses caused by sudden equipment shutdown. This is crucial to ensuring the overall performance of the equipment and user satisfaction. Currently, the existing equipment for testing hidden switches generally uses a cylinder to frequently drive a pressing block to press the switch button. However, this test method can only determine the durability of the switch, as well as the elasticity and reset performance of the switch, and cannot detect whether the sensitivity of the switch activation area is uniform. In the actual use of the hidden switch, the position of the pressing surface where the user touches the switch is different each time. Sometimes, due to uneven sensitivity in the entire activation area of ​​the switch, the switch cannot be effectively opened and closed at one time, affecting the overall performance of the switch and reducing user satisfaction. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the present invention mainly provides a device for testing the opening and closing life of a hidden switch, so as to solve the technical problem mentioned in the above background technology that the current equipment for testing hidden switches can only test the durability of the switch by pressing at a fixed point, and for those hidden switches with a larger pressing surface, it is impossible to determine whether the sensitivity of each position of the pressing surface is uniform.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A device for testing the opening and closing life of a hidden switch, comprising a positioning and placing mechanism, the positioning and placing mechanism comprising a base plate and a movable plate, the movable plate being located on the upper side of the base plate, a plurality of placement slots being arranged on the movable plate, each of the placement slots being arranged with a hidden switch body, a driving mechanism being arranged on the base plate, the driving mechanism comprising a plurality of support frames, a lifting plate being arranged on the support frames, a plurality of pressing assemblies being linearly arranged at equal intervals on the lifting plates, each of the pressing assemblies comprising a mounting block, the mounting block and the lifting plate being detachably connected, each of the mounting blocks being slidably connected with a movable frame, each of the movable frames being arranged with an elastic pressing head, and the elastic pressing head being located above the corresponding hidden switch body.

[0006] Preferably, each of the mounting blocks is connected to a first motor via bolts, a screw rod is provided at the output end of the first motor, the screw rod is rotatably connected in the corresponding inner cavity of the mounting block, and a nut seat is provided on each of the screw rods, which is connected to the corresponding movable frame.

[0007] Preferably, each of the movable frames is provided with a second motor, and an output end of the second motor is connected to an upper end of a corresponding elastic pressing head.

[0008] Preferably, positioning pressing plates are hingedly connected at both sides of the opening of each placement slot.

[0009] Preferably, a plurality of limit sliding blocks are arranged on the lower side of the movable plate, each of the limit sliding blocks is slidably connected to a limit sliding rail, and the limit sliding rail is arranged on the bottom plate.

[0010] Preferably, the driving mechanism also includes a plurality of support blocks, the support blocks and the support frames are detachably connected, the support blocks are connected to a first connecting block and a second connecting block by bolts, and the first connecting block and the second connecting block are respectively movably connected to a stabilizing rod and a push rod, and a docking block is commonly provided at the lower end of each stabilizing rod and the corresponding push rod, and the docking block and the lifting plate are connected by bolts.

[0011] Preferably, a cylinder is provided on one of the second connection blocks, and an output end of the cylinder is connected to an upper end of a push rod directly below.

[0012] Preferably, one of the support frames is connected to a controller and a timer by bolts, and the controller and the timer are electrically connected.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention realizes that in the process of testing the opening and closing life of the hidden switch, the sensitivity of different positions of the pressing surface of the hidden switch is tested by pressing at multiple points through the installation block, the screw rod, the nut seat, the moving frame, the elastic pressing head, the first motor, the placement slot, the positioning pressure plate, the limit slider and the limit slide rail, so as to better simulate various situations that may be encountered in actual use, and check whether the sensitivity of the switch is uniform in the entire activation area. If the sensitivity of a specific area is lower than that of other areas, it may indicate that the switch has design or manufacturing defects. In some cases, the edge of the switch may be more difficult to activate or more sensitive than the central area. Multi-point pressing can reveal this edge effect and help discover possible deviations in the mechanical components of the switch, such as uneven spring force or poor contact of contacts, which helps to evaluate the stability of the switch after long-term use and ensure that the switch can provide users with a good user experience in different use environments. The test results can also provide feedback for product design and help manufacturers improve the design of switches.

[0014] (2) The present invention realizes frequent pressing of the hidden switch by means of the support frame, support block, first connecting block, stabilizing rod, second connecting block, stabilizing rod, docking block, cylinder and lifting plate, so as to test the durability of the internal mechanical properties of the switch. Moreover, the controller and the timer cooperate with each other to adjust the pressing time of the elastic pressing head each time the switch is pressed, so as to determine whether the internal electrical properties of the switch are intact. By changing the pressing time, the user can simulate the situation of pressing the switch quickly or for a long time, so as to check the reliability of the switch contact point under long-term contact or frequent operation. Pressing the switch under different time lengths (for example, short press, long press, super long press) is conducive to the staff to observe whether the switch can stably connect and disconnect the circuit and record effective test data, so as to better understand product quality problems and have good market prospects.

[0015] (3) The present invention realizes the press test of multiple hidden switches at the same time by arranging a bottom plate, a movable plate, multiple placement slots, a positioning pressure plate, a limit slider, a limit slide rail and multiple elastic pressing heads. Compared with the traditional one-by-one testing, the detection efficiency of switch products is greatly improved. The second motor can drive the elastic pressing head to rotate, simulating the rotational pressing action, which is used for the test of rotational pressing type switches, thereby improving the range of switch type testing.
