Due to the battery life, the charging port of new energy vehicles is used more frequently than the refueling port of original fuel vehicles. At the same time, the customer's user experience is also increasingly valued. The opening of the small door of the car charging port is usually achieved by pressing the cover to connect the internal button. Among them, the comfortable pressing force will also directly affect the consumer's intuitive experience. Therefore, the pressing force of the button of the charging door has also become an important data that needs to be measured and saved during the assembly process. How to better monitor the pressing force when the switch button inside the charging door is turned on and off has become a technical problem that needs to be solved at present. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-Figure 4 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0020] The utility model proposes a button switch pressure monitoring mechanism, which can be applied to different occasions. The following is an example of the pressure detection of the button switch of the car charging door when it is turned on and off. Figure 4 As shown, the pressing portion 91 is the connection point of the small door switch button.
[0021] The pressure monitoring mechanism includes a propulsion component, which is used to propel the test end back and forth, and includes a servo electric cylinder 1; the driving end of the servo electric cylinder 1 is connected to a detection component, which is used to enter the charging door to press the button, and includes a guide end 3 and a pressing guide post 7 inserted into the guide end 3. The distal end of the guide end 3 is conical. The pressing guide post 7 is movably disposed on the guide end 3, and the distal end of the pressing guide post 7 extends beyond the farthest end of the guide end 3.
[0022] A buffer mechanism 6 is provided at one end of the pressing guide column 7 and is connected to the servo electric cylinder, and the buffer mechanism 6 is connected to a pressure detection mechanism 3. The buffer mechanism 6 is a compression spring, and the pressure detection mechanism 3 is a pressure detection sensor.
[0023] Specifically, the driving end of the servo electric cylinder is connected to the connecting mounting plate 2 , and one end of the pressure detection mechanism is connected to the connecting mounting plate 2 .
[0024] The guide end 3 is provided with a receiving cavity 31 , and the pressure detection mechanism 3 is placed in the receiving cavity 31 . The pressure detection mechanism 3 is connected to an external device via a signal line.
[0025] A guide sleeve 4 is provided in the guide end 3, and the guide sleeve 4 is coaxial with the servo electric cylinder. The pressing guide post 7 is placed in the guide sleeve 4, and the compression end 5 of the buffer mechanism 6 abuts against the detection end of the pressure detection mechanism. When the pressing guide post 7 is pressed, the compression spring 6 is driven to be compressed in the direction of the pressure detection mechanism 3. The pressure of the pressing can be detected by the pressure detection mechanism 3.
[0026] In specific applications, the servo cylinder can be precisely controlled by PLC. When the servo cylinder is working, it will drive the connection mounting plate 2 to move, and drive the pressing guide column 7 to press the button switch position. Before touching the button, the servo cylinder advances quickly, and after touching the button, it will continue to advance at a slower speed. When the PLC electronic control system detects the power-on signal of the button switch and collects the pressure sensor value at this time, the servo cylinder stops advancing and returns to the starting state.
[0027] The principle used by the utility model is that by cooperating with the spring, the range of the force collected instantaneously can be enlarged. The conventional pressure sensor has a very small compression deformation during detection, which leads to a relatively large force fluctuation when detecting the switch signal. When collecting relatively small pressures, the accuracy rate is low and the ideal collection accuracy cannot be achieved. After adding the spring, it is equivalent to transferring the deformation of the pressure sensor to the spring, so it is more stable, more accurate and more reliable than direct measurement. At the same time, when the pressure detection sensor is selected, in order to achieve the theoretical accuracy, the maximum range needs to be sacrificed. The large range has low accuracy, and the high-precision range is small. The traditional direct detection method can easily exceed the range of the sensor in the event of an accidental collision, thereby damaging the pressure sensor. The utility model can well protect the sensor by adding a spring mechanism. When the spring force is exceeded, the guide column has been completely retracted into the guide end, so that the force will not exceed the designed maximum bearing capacity of the spring, thus well protecting the pressure sensor.
[0028] Finally, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
