[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] In this technical solution, a small household appliance button life testing device includes a base 1 and a testing mechanism 2. The testing mechanism 2 is installed on the upper wall of the base 1, and a button clamping frame 3 is installed on the upper wall of the base 1. The button clamping frame 3 is located below the testing mechanism 2, and a household appliance button module 4 is clamped and installed in the middle of the button clamping frame 3.

[0022] There are two button clamps 3, which are respectively set on the left and right sides of the base 1. The home appliance button module 4 is set between the two button clamps 3. The button clamp 3 includes a side plate 31, a threaded hole 32, a screw 33, a main clamping plate 34, a sliding groove 35 and a secondary clamping plate 36. The side plate 31 is installed on the side wall of the base 1. The side wall of the side plate 31 has a threaded hole 32. The screw 33 is rotatably installed in the threaded hole 32. The main clamping plate 34 is installed on the side wall of the screw 33. The upper wall of the main clamping plate 34 has a sliding groove 35. The secondary clamping plate 36 is slidably installed in the sliding groove 35. The main clamping plate 34 and the secondary clamping plate 36 are both in contact with the side wall of the home appliance button module 4.

[0023] In this technical solution, the home appliance button module 4 is clamped by the button clamping bracket 3, and then the home appliance button module 4 can be pressed by the detection mechanism 2 to test the pressing life of the home appliance button module 4.

[0024] In this device, the auxiliary clamping plate 36 can slide up and down within the sliding groove 35 on the main clamping plate 34, thereby adjusting its overall height to make it suitable for home appliance button modules 4 with different pressing strokes. This avoids the clamping plate obstructing the home appliance button module 4, which would cause the home appliance button module 4 to not be pressed properly and affect the accuracy of the test results.

[0025] In some technical solutions, the testing mechanism 2 includes a telescopic plate 21, a motor 22, a turntable 23, a connecting rod 24, a sliding sleeve 25, a piston 26, and a top rod 27. The telescopic plate 21 is installed on the upper wall of the base 1. The motor 22 is installed on the upper wall of the telescopic plate 21 and is electrically connected to an external power source. The turntable 23 is installed at the output end of the motor 22. One end of the connecting rod 24 is rotatably installed on the side wall of the turntable 23. The piston 26 is installed on the other end of the connecting rod 24. The sliding sleeve 25 is installed on the side wall of the telescopic plate 21. The piston 26 is slidably installed in the sliding sleeve 25. One end of the top rod 27 is installed on the lower wall of the piston 26. The other end of the top rod 27 can be attached to the upper wall of the home appliance button module 4.

[0026] In this technical solution, during testing, the height of the telescopic plate 21 is first adjusted so that when the top rod 27 moves to the lowest point, it can completely press down the home appliance button module 4. Then the height of the telescopic plate 21 can be fixed. A locking bolt is provided on the telescopic plate 21, and the height of the telescopic plate 21 can be fixed by the locking bolt.

[0027] After the height of the telescopic plate 21 is adjusted, the motor 22 can be started, which will drive the turntable 23 to rotate, thereby driving the piston 26 to slide inside the sliding sleeve 25 through the connecting rod 24, so that the push rod 27 continuously presses the home appliance button module 4.

[0028] At the same time, the number of rotations of the motor 22 is monitored by an external monitoring device. For each rotation of the motor 22, the push rod 27 will press the appliance button module 4 once. By observing the number of rotations of the motor 22 when the appliance button module 4 is scrapped, the pressing life of the appliance button module 4 can be obtained.

[0029] In some technical solutions, the left and right side walls of the sliding sleeve 25 are provided with relief grooves 5, and the connecting rod 24 can pass through the side wall of the sliding sleeve 25 through the relief grooves 5.

[0030] In this technical solution, the clearance groove 5 can make way for the connecting rod 24, so as to prevent the sliding sleeve 25 from affecting the displacement of the connecting rod 24.

[0031] In some technical solutions, the home appliance button module 4 includes a button body 41 and a keycap 42. The keycap 42 is installed on the upper end of the button body 41, and the main clamping plate 34 and the secondary clamping plate 36 can fit against the side wall of the button body 41.

[0032] In this technical solution, the side wall of the main clamping plate 34 is also provided with locking bolts, which can fix the position of the secondary clamping plate 26 by means of the locking bolts.

[0033] In some technical solutions, a rubber buffer pad 6 is fitted to the upper wall of the base 1. The rubber buffer pad 6 is located below the home appliance button module 4, and the upper wall of the rubber buffer pad 6 is provided with anti-slip protrusions 7.

[0034] In this technical solution, the rubber buffer pad 6 can provide cushioning and support for the appliance button module 4. At the same time, anti-slip protrusions 7 are also provided on its top to increase the friction between the appliance button module 4 and the rubber buffer pad 6, which can effectively prevent the appliance button module 4 from shifting during detection.

[0035] In some technical solutions, a rotary handle 8 is installed at the end of the screw 33 that is away from the main clamping plate 34.

[0036] In this technical solution, the screw 33 can be rotated more conveniently by rotating the handle 8.

[0037] Working principle: During testing, after clamping the appliance button module 4 between the two button clamping frames 3, the height of the telescopic plate 21 is adjusted so that when the top rod 27 moves to the lowest point, it can completely press down the appliance button module 4. Then the height of the telescopic plate 21 can be fixed. The telescopic plate 21 is provided with locking bolts, and the height of the telescopic plate 21 can be fixed by locking the bolts.

[0038] After the height of the telescopic plate 21 is adjusted, the motor 22 can be started, which will drive the turntable 23 to rotate, thereby driving the piston 26 to slide inside the sliding sleeve 25 through the connecting rod 24, so that the push rod 27 continuously presses the home appliance button module 4.

[0039] At the same time, the number of rotations of the motor 22 is monitored by an external monitoring device. For each rotation of the motor 22, the push rod 27 will press the appliance button module 4 once. By observing the number of rotations of the motor 22 when the appliance button module 4 is scrapped, the pressing life of the appliance button module 4 can be obtained.
