Description

Technical Field

[0001] This utility model relates to the field of home appliance testing technology, specifically to a device for testing the lifespan of buttons on home appliances. Background Technology

[0002] The lifespan test of home appliance buttons is a durability test conducted on the operating buttons of home appliances (such as television and air conditioner remote controls). It aims to evaluate the reliability of buttons in long-term use through standardized experiments and determine their cycle from normal operation to failure. It is a key link in the quality control of home appliances.

[0003] Button life testing machines are typically used to test buttons. However, due to the varying surface areas of the buttons on the equipment, if the diameter of the pressing head is much smaller than the button size, and the contact area ratio (S1 / S2) is less than 50%, the local pressure will increase significantly, causing premature plastic deformation of the button (such as keycap dents), resulting in test results that deviate from actual usage scenarios. Conversely, if the pressing head area is too large, it will affect adjacent buttons during the pressing test, causing false presses. The "number of presses" recorded by the equipment will contain a large number of invalid triggers, leading to inaccurate data. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1 to 3 This utility model provides a technical solution: a button life detection device for home appliances, including a base 1 with an internal mounting cavity 101, two guide rods 3 vertically and movably inserted on the base 1, one end of the guide rods 3 extending into the mounting cavity 101, and the other end being fixedly connected to a top bar 4, which is located above the base 1. A bracket 5 is also fixedly connected to the guide rods 3, and a rotating shaft 9 is rotatably inserted at the end of the bracket 5. One end of the rotating shaft 9 is fixedly connected to multiple circumferentially distributed connecting rods 10, and the other end of the connecting rods 10 is fixedly connected to a pressing head 11, the surface areas of each pressing head 11 being different; that is, to meet the needs of button pressing.

[0028] By employing multiple pressing heads 11 with different surface areas, the areas of the pressing heads 11 and the buttons on the remote control 13 are matched to each other, thereby ensuring that the pressing heads 11 accurately and stably press the buttons and obtain accurate pressing life data; and the position of the pressing heads 11 is adjusted by a rotatable shaft 9 so that the pressing heads 11 can be aligned with the buttons to be tested on the remote control 13.

[0029] See Figure 5 The bracket 5 has a limiting cavity 501 at one end, and one end of the rotating shaft 9 extends into the limiting cavity 501. The rotating shaft 9 has circumferentially distributed insertion holes 901, and the top of the bracket 5 is provided with a locking component 12 for limiting the rotating shaft 9.

[0030] The angle of the rotating shaft 9 is locked by the locking component 12, which also locks the position of the pressing head 11 to prevent shaking and ensure that the pressing head 11 used at this time can stably squeeze the button in the vertical direction.

[0031] See Figure 4 and Figure 5 The locking assembly includes a support block 121 fixed to the top of the bracket 5. A pin 124 is movably inserted into the support block 121. A stop block 122 is fixedly connected to the upper end of the pin 124. A spring 123 is fixedly connected between the stop block 122 and the support block 121. The top of the bracket 5 has an insertion port 502 communicating with the limiting cavity 501. The lower end of the pin 124 passes through the insertion port 502 and is inserted into the insertion hole 901.

[0032] Move the lever 10 to rotate the pressing head 11 so that the pressing head 11 is aligned with the button 13 on the remote control, i.e., set vertically downwards. At this time, release the stop block 122, the spring 123 releases its elastic force, and pulls the stop block 122 and the pin 124 down, so that the lower end of the pin 124 passes through the socket 502 and is inserted into the socket 901. At this time, the rotating shaft 9 and the pressing head 11 are locked to ensure the stability during the pressing detection process.

[0033] See Figures 6-8 The top of the base 1 is also provided with a clamping assembly 2 for fixing the remote control 13. The clamping assembly 2 includes a support plate 21 fixed to the top of the base 1, and two studs 22 fixedly connected to the support plate 21. The two studs 22 are together fitted with a pressure strip 23, and a nut 24 is threaded on the upper end of the studs 22.

[0034] Before performing the press test, the remote control 13 needs to be fixed. That is, the remote control 13 is placed on the support plate 21, and then the pressure strip 23 is pressed down to make contact with the remote control 13. Then, the pressure strip 23 is pressed by tightening the nut 24 at the upper end of the stud 22, thus fixing the remote control 13. It should be noted that the products containing buttons in this application are not limited to the remote control 13.

[0035] See Figure 6 A screw rod 6 is threaded into the top bar 4. The lower end of the screw rod 6 is rotatably connected to the bracket 5 through a bearing. A handwheel 7 is fixedly connected to the upper end of the screw rod 6.

[0036] The remote control 13 is positioned by the clamp assembly 2 to prevent it from shifting during the test; then, by rotating the handwheel 7, the screw 6 is driven to rotate and descend, so that the bracket 5 descends vertically along the guide rod 3, so that the pressing head 11 makes slight contact with the button; this is the debugging work before the pressing test.

[0037] See Figure 2 The mounting cavity 101 is equipped with a drive assembly 8 for driving the guide rod 3 to move vertically and reciprocally. The drive assembly 8 includes a motor 82 fixed to the bottom wall of the mounting cavity 101, a lead screw 83 fixed to the output end of the motor 82, and a lifting bar 81 threaded onto the lead screw 83. The two ends of the lifting bar 81 are fixed to the lower end of the guide rod 3.

[0038] By starting the motor 82, the lead screw 83 is driven to rotate. The lead screw 83 drives the lifting bar 81 to move vertically back and forth, thus completing the up and down reciprocating movement of the pressing head 11. The pressing head 11 detects the button, and the number of presses can be set. After completion, the machine stops.

[0039] In addition, the drive stroke of motor 82 can be set by an encoder, and the number of presses can be counted by a counter. The above structure is prior art and is not the direction of improvement of this application, so it will not be described in detail.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
