[0039] Embodiment 1:

[0040] This embodiment provides a switch life test device, which is used to detect the life of a switch. Figure 1 The switch includes a panel 101 and a knob 102, and the knob 102 is rotatably arranged on the panel 101. As the actual number of rotations or the actual rotation angle of the knob 102 increases, the connection strength between the knob 102 and the panel 101 will gradually decrease. When the knob 102 and the panel 101 are separated, the actual number of rotations or the actual rotation angle of the knob 102 can be used to characterize the life of the switch.

[0041] See Figure 2-Figure 5 The switch life test device includes a base 1, a first positioning component 2, a first tooth member 3, a second positioning component 4, a second tooth member 5 and a power source 6.

[0042] The first positioning assembly 2 includes a pushing device 21 and a positioning member 22, both of which are arranged on the base 1. The pushing device 21 can be a cylinder or an electric push rod to allow the pushing device 21 to approach or move away from the positioning member 22. The pushing device 21 can press the panel 101 on the positioning member 22 by approaching the positioning member 22, so that the panel 101 is positioned on the positioning member 22. When the pushing device 21 moves away from the positioning member 22, the panel 101 can be taken out from the positioning member 22.

[0043] In order to improve the positioning effect of the panel 101, a third positioning groove 221 is opened on the positioning member 22. The third positioning groove 221 is adapted to the shape of the panel 101. The pushing device 21 can press the panel 101 in the third positioning groove 221, so that the third positioning groove 221 can limit the shaking of the panel 101 on the base 1.

[0044] Furthermore, a sidewall of the third positioning groove 221 is provided with an escape hole 222, which is in communication with the third positioning groove 221. Accordingly, when the pushing device 21 pushes the back of the panel 101, the knob 102 located on the front of the panel 101 can escape through the escape hole 222. The knob 102 is inserted into the escape hole 222, so that the panel 101 can still be rotated on the panel 101 when the panel 101 is positioned.

[0045] In addition, the avoidance effect of the avoidance hole 222 on the knob 102 also allows the knob 102 to contact the first toothed member 3, so that the knob 102 can at least obtain circumferential positioning on the first toothed member 3 to ensure that the knob 102 and the first toothed member 3 can rotate synchronously.

[0046] See also Figure 6 and Figure 7 The first toothed member 3 includes an inner gear ring 31. Since the outer wall of the knob 102 is also provided with teeth, the knob 102 obtained by the avoidance hole 222 can be passed through the middle of the inner gear ring 31 to engage with the inner gear ring 31, thereby realizing the circumferential positioning of the knob 102 on the first toothed member 3.

[0047] The second positioning assembly 4 and the power source 6 are both arranged on the base 1. The power source 6 is transmitted to the second toothed member 5. The first toothed member 3 is rotatably arranged on the second positioning assembly 4. The second toothed member 5 is meshed with the first toothed member 3. Thus, the power source 6 can drive the first toothed member 3 to rotate on the base 1 via the second toothed member 5. When the panel 101 is positioned on the base 1, the rotation of the first toothed member 3 can control the knob 102 to rotate synchronously on the panel 101, thereby simulating the actual use process of the switch. When the panel 101 and the knob 102 are separated, the actual number of rotations of the first toothed member 3 can also be used to characterize the service life of the switch.

[0048] If the power source 6 is a motor, the first toothed member 3 can be a gear. In this embodiment, the power source 6 is a cylinder or an electric push rod, and the second toothed member 5 is a rack to match it. The power source 6 can drive the second toothed member 5 to move linearly on the base 1. The linear reciprocating motion of the second toothed member 5 can be converted into the alternating clockwise and counterclockwise rotation of the first toothed member 3.

[0049] In this embodiment, the first toothed member 3 further includes an outer gear 32 coaxially arranged with the inner gear ring 31, the inner gear ring 31 is fixed to the outer gear 32, wherein the first toothed member 3 is meshed with the second toothed member 5 via the outer gear 32. In addition, the second positioning assembly 4 includes a bracket 41 mounted on the base 1 and a rotating shaft 42 fixed on the bracket 41, the rotating shaft 42 is inserted in the middle of the outer gear 32, so that the outer gear 32 is rotatably arranged on the bracket 41.

[0050] Since the inner gear ring 31 and the outer gear 32 are connected, the end of the rotating shaft 42 can be abutted against the end of the knob 102 during the detection process, thereby improving the stability of the knob 102 when rotating and reducing the radial shaking of the knob 102 when rotating.

[0051] The second toothed member 5 is relatively long to ensure that the knob 102 can rotate a sufficient angle when it rotates counterclockwise or clockwise. Accordingly, the portion of the second toothed member 5 away from the power source 6 is more likely to deform, thereby causing the first toothed member 3 to slip. To this end, a slide rail 11 is provided on the base 1 of this embodiment, and the second toothed member 5 is slidably provided on the slide rail 11, so that the deformation of the first toothed member 3 is suppressed by the slide rail 11.

[0052] A certain pressure needs to be maintained between the first toothed member 3 and the second toothed member 5 to reduce the occurrence of tooth slippage. Therefore, once the first toothed member 3 and the second toothed member 5 are separated during the detection process, it is difficult to re-engage, so the movement range of the second toothed member 5 needs to be limited during the detection process. For this reason, a limiter 14 is further provided on the base 1 of this embodiment, and the limiter 14 is located near the end of the slide rail 11, so as to limit the movement of the second toothed member 5.

[0053] When testing different switches, the external gear 32 and the second gear 5 need to meet different transmission ratios, so the second gear 5 needs to be replaced frequently. In this embodiment, since the second gear 5 (rack) is a standard part, the second gear 5 lacks a structure that can be directly connected to the power source 6. The second gear 5 and the power source 6 can only be connected by other more complicated structures, which makes it inconvenient to replace the second gear 5.

[0054] In order to solve the above problems, the switch life test device further includes a slider 7, which is fixed at the output end of the power source 6 and is slidably arranged on the slide rail 11. A first positioning groove 71 is provided on the top of the slider 7, and the second toothed member 5 is embedded in the first positioning groove 71, so that the second toothed member 5 not only obtains the movement guidance of the slide rail 11 and the limiting function of the limiting member 14 through the slider 7, but also the second toothed member 5 can be disassembled and assembled on the slider 7 in a plug-in manner, which simplifies the replacement process of the second toothed member 5.

[0055] Of course, during the replacement process of the second toothed member 5, the second toothed member 5 cannot be directly disassembled and assembled due to the obstruction of the first toothed member 3. Therefore, the first toothed member 3 needs to avoid the second toothed member 5 before the second toothed member 5 is plugged in and replaced. Based on this, the present embodiment provides two solutions to allow the first toothed member 3 to avoid the second toothed member 5.

[0056] In the first solution, a fourth positioning groove 13 is provided on the base 1, and the limiting member 14 is embedded in the fourth positioning groove 13, and the limiting member 14 can be assembled and disassembled on the base 1 by plugging and unplugging. When the limiting member 14 is removed, the slider 7 can separate the first tooth member 3 and the second tooth member 5 by moving, and then the second tooth member 5 can be replaced.

[0057] The second solution is that the base 1 is provided with a second positioning groove 12, and the bracket 41 is embedded in the second positioning groove 12. When the switch is removed from the positioning member 22, the second positioning assembly 4 and the first tooth member 3 can be directly removed from the base 1 by plugging and unplugging, and then the second tooth member 5 can be replaced.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
