Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to a mechanical button testing device. Background Technology

[0002] With increasing global focus on reducing greenhouse gas emissions and improving energy efficiency, electric vehicles (EVs) have entered a period of rapid development. As a representative of green transportation, EVs not only help reduce dependence on fossil fuels but also significantly reduce exhaust emissions, combating air pollution and climate change. Against this backdrop, the importance of charging stations as energy replenishment points for EVs is self-evident. They are indispensable infrastructure in the EV ecosystem, directly impacting EV adoption and the user's charging experience. The reliability and charging efficiency of charging stations are key factors driving the development of the EV market.

[0003] Mechanical buttons play a crucial role in the operation and monitoring systems of charging stations. Users use these buttons to start or stop the charging process, adjust charging parameters, or initiate emergency shutdowns. The reliability of these buttons directly affects user convenience and the safety of the charging station. Therefore, ensuring the durability and consistency of mechanical buttons is essential for improving the overall quality and performance of the charging infrastructure. However, current testing of mechanical buttons primarily relies on traditional manual inspection and market feedback methods. These methods have significant drawbacks in mechanical button testing, including high subjectivity, low efficiency, high cost, insufficient accuracy, incomplete data recording, delayed response, inability to predict failure modes, susceptibility to environmental factors, limited testing scope, and safety risks. These limitations prevent the timely detection and resolution of potential problems with charging station mechanical buttons, increasing operating costs and equipment failure rates, and hindering the further development of charging technology.

[0004] Therefore, in order to improve the accuracy, efficiency and reliability of testing, there is an urgent need for a mechanical button testing device to meet the high-performance testing requirements of the modern electric vehicle charging pile industry. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical button testing device to overcome the shortcomings of existing mechanical button testing equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mechanical button testing device includes a simulation testing component and a bottom fixing component, wherein the simulation testing component includes:

[0008] The support component, as the skeleton of the simulation test assembly, supports other components. The bottom of the support component is fixed to the bottom fixing component, and the other components in the simulation test assembly are fixed to the top.

[0009] The pressing simulation component includes a power unit mounted on a support component. A servo motor is connected to a button contact via a transmission unit. The button contact simulates user operation, performing a pressing test on a mechanical button. The power unit provides power to the transmission unit, which then transmits the power to the button contact, driving the button contact to press the mechanical button below, simulating the use scenario of the mechanical button and thus achieving the testing effect.

[0010] The detection component, mounted on the support component, performs motion detection on the transmission unit to ensure test accuracy.

[0011] The bottom fixing assembly provides a stable base for the entire testing device, including a base, a bottom plate fixed on the base, and a button fixing component fixed on the bottom plate for fixing the mechanical button to be tested.

[0012] Furthermore, the support component includes a support frame, the bottom of which is fixed to the base plate of the bottom fixing component, and the upper part is fixed to a mounting back plate by a plurality of base plate connectors. The pressing simulation component and the detection component are mounted on the mounting back plate.

[0013] Furthermore, the transmission unit in the pressing simulation component includes a transmission shaft. One end of the transmission shaft is connected to the power unit via a flat key, and the other end is connected to a second slider via a crank. The transmission shaft and the crank are connected via ball bearings, and the crank and the second slider are also connected via ball bearings. The second slider is connected to a button contact via a connecting block. The connecting block is also connected to a limiting component, which restricts the movement range of the button contact to ensure the accuracy of the test.

[0014] Furthermore, the limiting component includes a linear guide rail arranged on the supporting component and a first slider slidably mounted on the linear guide rail. The first slider is fixedly connected to the connecting block. A stop block is also arranged below the linear guide rail. The stop block serves as the end limit of the linear guide rail to prevent the first slider from disengaging.

[0015] Furthermore, the detection component includes a rotation detection component and several sliding detection components. Both the rotation detection component and the sliding detection component are photoelectric switches. The rotation detection component is installed next to the drive shaft, and the sliding detection components are arranged sequentially next to the linear guide rail.

[0016] Furthermore, thin plates for easy detection are installed on both the drive shaft and the connecting block. The rotation detection component detects the rotation angle of the drive shaft through the thin plate on the drive shaft, and the sliding detection component detects the displacement distance of the connecting block through the thin plate on the connecting block, thereby detecting the displacement distance of the button contact.

[0017] Furthermore, the power unit includes a servo motor, which serves as a power source to drive the transmission unit and thereby drive the button contacts to simulate pressing the mechanical button. The servo motor is connected to a reducer, which reduces the speed of the servo motor and increases the transmission torque. The reducer is connected to the transmission unit.

[0018] Furthermore, the button fixing component includes a clamp and a lead screw fixing block, on which a lead screw assembly is mounted.

[0019] Furthermore, one end of the lead screw assembly used for clamping the component under test is equipped with a pressure block for clamping the mechanical button to be tested. The pressure block is moved by rotating the lead screw assembly to fix or release the component under test. The other end of the lead screw assembly is equipped with a handle for manually adjusting the lead screw assembly to accommodate components of different sizes.

[0020] Furthermore, the base is also equipped with buttons and a display screen. The buttons are used to start and stop the test, as well as to reset the test device in case of a malfunction. The display screen shows the number of actions during the test, providing visualization of the test data. The buttons and display screen are electrically connected to the control system.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] This invention discloses a mechanical button testing device that uses a simulation testing component and a bottom fixing component to fix the mechanical button under test and simulate its usage scenario to complete the performance test. The testing device, employing a combination of a servo motor and a transmission unit, achieves precise control over the pressure and displacement of the button contact, effectively improving testing accuracy and reducing errors from manual inspection. Using this testing device not only improves testing efficiency but also reduces long-term operating costs. The standardized testing procedure of this device improves the consistency and repeatability of test results. Furthermore, the use of rotation and sliding detection components enables comprehensive monitoring of the button contact movement, ensuring the integrity of test data. In addition, the use of this testing device enhances the adaptability of the mechanical button testing process, as well as its data recording and analysis capabilities, allowing technicians to more intuitively control the testing process and read test results. The stability and durability of the testing device enable it to withstand long-term continuous operation, and its simple structure facilitates maintenance and repair. In summary, the mechanical button testing device of this invention overcomes the shortcomings of the prior art, provides a more efficient, accurate and reliable testing solution, significantly improves the quality and reliability of mechanical buttons for electric vehicle charging piles, and enhances user experience and market competitiveness.
