[0028] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0029] Nouns and pronouns relating to persons in this patent application are not limited to a specific gender.

[0030] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the positional relationship between related parts, rather than to limit their absolute positions.

[0031] In this article, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order.

[0032] In this document, “parallel”, “perpendicular”, etc. are not strictly limited in mathematical and / or geometric senses, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0033] refer to Figure 1 As shown, the mechanical life test equipment provided by the present application includes a cover 40, a base 10 and a fixture 20, the cover 40 is installed on the base 10, and the cover 40 and the first surface of the base 10 surround and form a test cavity; the cover 40 includes a shell and an opening and closing door, the shell has an opening, and the opening and closing door is movably connected to the shell so as to be able to open or close the opening; the fixture 20 can pass through the opening and be detachably connected to the first surface of the base 10, the fixture 20 is located in the test cavity, and is used to fix the push button switch to be tested.

[0034] Based on the above technical solution, when a life test is required, the button switch to be tested can be fixed on the fixture 20, and then the fixture 20 can be detachably mounted on the first surface of the base 10, and then the opening is closed by using the opening and closing door to form a closed test chamber. The fixture 20 and the button switch to be tested are both located in the test chamber. During the test, the cover 40 can play a protective role, that is, it can prevent various adverse factors from entering the test chamber and causing adverse effects on the test, and it can also prevent the workpiece to be tested from accidentally flying out of the test chamber during the test, thereby ultimately improving the test safety.

[0035] Since the fixture 20 can pass through the opening and be detachably connected to the first surface of the base 10, different types of fixtures 20 can be installed on one base 10, and one type of fixture 20 can be used to fix one type of button switch to be tested, so one life test device can be used to test multiple types of button switches. Therefore, the mechanical life test device provided by the present application can test multiple types of button switches to be tested, reducing the testing cost;

[0036] Moreover, since the fixture 20 can pass through the opening and is detachably connected to the first surface of the base 10, the fixture 20 can also be moved to other special test spaces, such as high temperature test spaces and high voltage test spaces, to perform tests in special scenarios, thereby testing more performance indicators of the button switch to be tested. For example, the button switch can be in the form of a flat button, a double-position button, a mushroom button, a knob, etc. By replacing different fixtures 20, mechanical life tests of different products such as flat buttons, double-position buttons, mushroom buttons, and knobs can be achieved. At the same time, the "mobile" fixture 20 can be placed in environmental equipment such as a temperature and humidity oven and a dust box to achieve mechanical life tests of button products in harsh environments.

[0037] In addition, since the opening and closing door is movably connected to the housing, the cover 40 can be fixed on the base 10, and the fixture 20 can be placed in the test cavity or taken out of the test cavity through the opening without removing the cover 40, which is easy to operate. The opening and closing door can be a flip door or a sliding door.

[0038] In the present application, "up and down" can be defined by the distribution position between the fixture 20 and the base 10, the base 10 is located below the fixture 20, the first surface of the base 10 can be the upper surface, and the cover 40 is located above the base 10. In actual use, the "up and down" direction can be consistent with the direction of gravity. The upper surface of the base 10 can be arranged horizontally, and the guide bar 30 is arranged on the upper surface of the base 10 and extends in the horizontal direction. The opening and closing door is located on the side of the cover 40; the fixture 20 can be pushed into the test cavity like a drawer, or pulled out of the test cavity.

[0039] In one example, at least a portion of the cover 40 is transparent, so that it is convenient to observe whether the fixture 20 is properly installed on the base 10 and to observe the state change of the workpiece to be tested during the test process.

[0040] In a possible embodiment, the fixture 20 is detachably slidably connected to the base 10 through a sliding connection structure, and the life test device further includes a positioning member connected between the fixture 20 and the base 10 to position the fixture 20. Based on this technical solution, the fixture 20 can be conveniently fixed to the base 10 or removed from the base 10.

[0041] In one possible embodiment, reference Figure 1 and Figure 3The sliding connection structure includes two symmetrical and spaced guide bars 30 fixed on the base 10, the guide bars 30 include a first portion 31 and a second portion 32 sequentially distributed in a direction away from the first surface, the first portion 31 is fixed on the base 10, and the second portion 32 is fixed on the outer area of ​​the first portion 31; the clamp 20 includes a first side and a second side opposite to each other, the first side and the second side are respectively overlapped on the inner area of ​​the first portion 31 of the two guide bars 30, and the clamp 20 is located between the second portions 32 of the two guide bars 30, and the clamp 20 can slide on the inner area of ​​the first portion 31. In this way, the clamp 20 can slide along the inner area of ​​the first portion 31 and be limited by the two second portions 32. In other words, the space between the two guide bars 30 is equivalent to forming a slide groove, the bottom wall of the slide groove is the inner area of ​​the first portion 31, and the main body 21 can slide in the slide groove.

[0042] Among them, the inner area and the outer area of ​​the first part 31 can be understood as two areas on the upper surface of the first part 31. There is a spacing area between the two conductive bars 30. The part farther from the spacing area is called the outer area, and the part closer to the spacing area is called the inner area.

[0043] In a possible embodiment, the clamp 20 includes a main body 21, a clamping member 22 and a roller. The clamping member 22 is fixed to the side of the main body 21 away from the first surface, and is used to clamp the button switch to be tested; rollers are installed on the opposite sides of the main body 21, and the rollers are supported by the inner area of ​​the first part 31. In this way, the clamp 20 can slide more smoothly and with less noise in the inner area of ​​the first part 31 through the rolling of the rollers, thereby reducing the resistance when the clamp 20 slides out of the slide groove or slides into the slide groove. Specifically, the clamping member 22 is located above the main body 21, and the side surface of the main body 21 close to the base 10 is the lower surface.

[0044] In one possible example, in one example, reference Figure 2 A handle 24 may be provided on both the first side and the second side of the clamp 20. In this way, the clamp 20 can be conveniently moved by holding the handle 24. Specifically, the handle 24 may be fixed on the main body 21.

[0045] In one possible example, reference Figure 4 The positioning member is a positioning pin, a positioning hole 11 is provided on the base 10, and an avoidance hole is provided on the main body 21, and the positioning pin passes through the avoidance hole and is inserted into the positioning hole 11. By fixing the positioning pin, it can be ensured that the fixture 20 will not shake or shift on the base 10 during the test.

[0046] The positioning hole 11 may be a threaded hole, and the end of the positioning pin may be provided with an external thread so as to be threadedly connected with the positioning hole 11, thereby ensuring more accurate positioning.

[0047] refer to Figure 1 The life test equipment provided in the present application may also include a test device, a monitoring device, an electric control unit 50 and a bracket 60. The test device is used to complete the test action, and the monitoring device is used to monitor the performance changes of the workpiece to be tested. The test device and the monitoring device can be set on the fixture 20, and the test device and the monitoring device can be connected to the electric control unit 50 through electrical lines, so that the test device can be controlled by the electric control unit 50, and the performance parameters monitored by the monitoring device can be obtained.

[0048] In one example, the base 10 and the electric control unit 50 are both mounted on a bracket 60 , and moving wheels may be provided at the bottom of the bracket 60 to facilitate the movement of the life test equipment.

[0049] In one example, the electric control unit 50 may include an HMI (Human Machine Interface) display screen, a PLC, a solenoid valve, a relay, etc., which are electrically connected and can be mainly used to control the action of the test device. The HMI display screen is electrically connected to the PLC, and the action parameters can be set through the HMI display screen. The HMI display screen can also display the device status and various performance parameters.

[0050] In one example, the life test equipment may further include a cylinder throttle valve, which is used in conjunction with the fixture 20 to fix and control the movement of the workpiece to be tested, such as fixing and controlling the movement of a button.

[0051] In one possible embodiment, reference Figure 2 The life test equipment also includes an electrical plug and an electrical socket 23, which match each other and can be plugged together detachably. One of the electrical plug and the electrical socket 23 is set on the main body 21, and the other is set on the base 10. In addition, the test device and the monitoring device are electrically connected to the electrical plug or the electrical socket 23 on the main body 21, respectively, and the electrical control unit 50 is electrically connected to the electrical socket 23 or the electrical plug on the base 10. In this way, after the fixture 20 is installed on the base 10, the electrical plug and the electrical socket 23 can be plugged together, so that the test device and the monitoring device are electrically connected to the electrical control unit 50, respectively, and then the electrical control of the test device and the monitoring device can be realized; when the fixture 20 needs to be removed from the base 10, the electrical plug and the electrical socket 23 can be separated without loss.

[0052] In a possible example, the number of electrical plugs and electrical sockets 23 is the same and at least two, at least one of which is electrically connected to the test device, and at least the other is electrically connected to the monitoring device; all electrical plugs or electrical sockets 23 are arranged on the same side of the main body 21. In this way, the entire fixture 20 looks neat and orderly.

[0053] In one example, the electrical plug may be an aviation plug, and the electrical socket 23 may be an aviation socket.

[0054] The process of removing the fixture 20 from the life test equipment can be as follows: disconnect the air source, unplug the aviation plug, loosen the positioning pin, and pull out the fixture 20 along the guide bar 30; the process of installing the fixture 20 on the life test equipment can be as follows: push the new fixture 20 along the guide bar 30, tighten the positioning pin, close the aviation plug, and turn on the air source.
