Description

Technical Field

[0001] This utility model relates to the field of high-frequency life testing technology for buttons, and in particular to a high-frequency life testing machine for car navigation button buttons. Background Technology

[0002] With the rapid development of the automotive industry, car navigation systems are becoming increasingly popular as important devices for enhancing driving experience and ensuring driving safety. As key components for user interaction with the navigation system, the buttons on car navigation systems require frequent operation. Therefore, the lifespan of the buttons directly affects the overall performance and user experience of the navigation system. Premature damage to the buttons during use not only inconveniences users but may also affect driving safety. Therefore, during the production of car navigation systems, batch sampling inspections are necessary to test the button lifespan of the sampled devices.

[0003] Current car navigation button high-frequency life testers use a vibration motor to drive a pressing head to continuously and frequently compress the buttons to test their lifespan. However, in actual operation, the buttons will rub against the edge of the navigation device, and the high-frequency pressing will cause them to heat up. The heated buttons will be damaged faster during testing, which may affect the accuracy of the test results. However, in actual use, the pressing frequency is generally not high, so it will not cause them to heat up excessively. Utility Model Content

[0007] Furthermore, a third electric telescopic rod is provided on the connecting arm, and the output end of the third electric telescopic rod is fixedly connected to the jet box.

[0008] To facilitate clamping of the navigator, preferably, a fixing plate is symmetrically fixedly connected to the test platform, a first electric telescopic rod is fixedly connected to the fixing plate, and a clamping plate is fixedly connected to the output end of the first electric telescopic rod.

[0009] To facilitate different pressing pressures, a connecting shaft is further provided on the vibration shaft, a sliding cavity is provided inside the connecting shaft, a sliding rod is slidably provided at the end of the sliding cavity, a sliding plate is slidably provided inside the sliding cavity, a spring is fixedly connected between the sliding plate and the sliding rod, a second electric telescopic rod is fixedly connected to the connecting shaft, the output end of the second electric telescopic rod is fixedly connected to the sliding plate, and a plurality of second air nozzles corresponding to the sliding rod are provided on the air jet box.

[0012] Compared with the prior art, this utility model provides a high-frequency lifespan testing machine for car navigation system buttons, which has the following advantages:

[0013] 1. This car navigation button high-frequency life tester uses a vibration motor to drive a vibration shaft to vibrate at high frequency.

Gas is delivered to the air jet box by an air pump and then sprayed out through the first air jet nozzle to cool the button. This prevents the button from overheating during continuous high-frequency pressing tests, which would affect the accuracy of the test results and make the test results more consistent with reality.

[0014] 2. This high-frequency lifespan tester for car navigation buttons, by setting a sliding rod and a spring, can prevent the extrusion head from applying excessive pressure to the buttons, thus preventing button damage. Furthermore, by adjusting the position of the sliding plate with a second electric telescopic rod, the extrusion force of the sliding rod on the buttons can be adjusted, thereby facilitating multi-dimensional testing.

[0015] 3. This car navigation button high-frequency life tester can obtain the squeezing force of the squeezing head on the button through a pressure sensor, which facilitates precise adjustment of the second electric telescopic rod.

[0016] The parts not covered in this device are the same as or can be implemented using existing technologies. This utility model cools down the buttons to prevent the temperature rise of the buttons during continuous high-frequency pressing tests from affecting the accuracy of the test results, making the test results more in line with reality.

[0024] A fixing plate 101 is symmetrically fixedly connected to the test bench 1. A first electric telescopic rod 102 is fixedly connected to the fixing plate 101. A clamping plate 103 is fixedly connected to the output end of the first electric telescopic rod 102.

[0025] When conducting a high-frequency life test on the buttons of a car navigation system, the car navigation system is first placed on the test platform 1, and the first electric telescopic rod 102 is activated so that the clamping plate 103 clamps and fixes the navigation system.

[0026] The vibration motor 2 is started, which drives the vibration shaft 201 to vibrate at high frequency. The vibration shaft 201, through the connecting shaft 301, causes the extrusion head 3 to press the button at high frequency, thereby conducting a high-frequency pressing life test. During the pressing process, the position of the air box 401 is adjusted by the third electric telescopic rod 405 so that the first air nozzle 402 can correspond to the button to be tested. The air pump 4 delivers gas to the air box 401 and then sprays it out through the first air nozzle 402 to cool the button and prevent the button from heating up during continuous high-frequency pressing test, which would affect the accuracy of the test results and make the test results more consistent with reality.

[0027] Example 2: Refer to Figures 1-3 The high-frequency life tester for car navigation button is basically the same as in Embodiment 1.

[0028] The connecting shaft 301 is threadedly connected to the vibration shaft 201.

[0029] A pressure sensor 306 is fixedly connected between the extrusion head 3 and the connecting shaft 301.

[0030] In actual testing, by setting the sliding rod 305 and the spring 304, it is possible to prevent the squeezing head 3 from applying excessive pressure to the button, which could damage the button. Furthermore, by adjusting the position of the sliding plate 303 through the second electric telescopic rod 307, the squeezing force of the sliding rod 305 on the squeezing head 3 can be adjusted, thus facilitating multi-dimensional testing.

[0031] The pressure sensor 306 can obtain the squeezing force of the extrusion head 3 on the button, which facilitates precise adjustment of the second electric telescopic rod 307. In actual use, the pressure sensor 306 transmits the pressure signal to the external microcomputer, and the microcomputer can control the first electric telescopic rod 102, the second electric telescopic rod 307, the third electric telescopic rod 405 and the air pump 4, etc.
