[0002] With the continuous advancement of science and technology, automotive electronic control technology has been widely used, promoting the rapid development of the automotive manufacturing field. However, there are also some safety hazards in the application of automotive electronic control technology. Among them, the rocker switch is one of the most frequently used components in the automotive electronic control system, and its stability and reliability directly affect the safe operation of the bus. During the operation of the car, once the rocker switch is out of control, it may cause danger and cause traffic accidents. Therefore, in order to reduce the occurrence of automotive electronic control problems, it is necessary to verify the stability and reliability of the rocker switch. The existing rocker switch detection method usually performs regular inspections on the rocker switches one by one after the rocker switches are installed on the vehicle to simply judge the basic functions of the rocker switches. This method not only has low detection efficiency, but also has a negative impact on the normal use and operation of the car, and the detection is very inconvenient. In addition, due to the small size of the rocker switch and the small pressing contact surface, higher requirements are placed on the refinement of the detection equipment. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are exemplary and are intended to provide further description of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0026] Example 1

[0027] like Figure 1 As shown, a rocker switch reliability verification system provided in this embodiment includes: 1. a first voltage converter; 2. a switch; 3. a time control module; 4. a solenoid valve; 5. a cylinder; 6. a rocker switch; 7. a position sensor; 8. an electronic counter; 9. an indicator light; 10. a load; and 11. a second voltage converter.

[0028] Specifically, the voltage converter refers to a DC power supply that can adjust voltage changes, wherein the first voltage converter 1 provides voltage for the system, and is connected to the time control module 3 through a switch 2 provided on the wiring harness, and transmits an electrical signal to the time control module 3; the time control module 3 is connected to the solenoid valve 4, and the electrical signal transmitted by the first voltage converter 1 is obtained and set at different time intervals and sent to the solenoid valve 4, the solenoid valve 4 receives the electrical signal from the time control module 3, and executes according to the received electrical signal to control the action frequency of the cylinder 5, and the cylinder 5 simulates the states of the same model of the rocker switch 6 at different powers and the different models of the rocker switch 6 at different powers in the test system. The cylinder 5 cooperates with the rocker switch 6, and the rocker switch 6 is opened and closed by controlling the cylinder rod to press the rocker switch 6, and the rocker switch 6 is pressed and tested by actions of different frequencies.

[0029] In this embodiment, the electrical signal obtained from the first voltage converter 1 is sent to the solenoid valve 4 at different time intervals through the set time control module 3, and then the solenoid valve 4 transmits voltage according to the received electrical signal, thereby controlling the action of the cylinder 5. Finally, the cylinder 5 simulates the states of the same model of rocker switches at different powers and different models of rocker switches at different powers in the test system through pressing actions of different frequencies, thereby realizing reliability tests and safety tests of the same model of rocker switches 6 at different powers and different models of rocker switches 6 at different times. Through the setting of the above system, the reliability of the rocker switches 6 used for installation can be verified before the mass production of automobiles. Not only can the problems be discovered and solved in advance, but also the inconvenience and tediousness of reliability verification of the rocker switches 6 after installation can be avoided. Compared with the traditional method, the testing capability is more comprehensive and efficient.

[0030] As a specific implementation method, the solenoid valve 4 is installed on one side of the cylinder 5, and the two are tightly coupled, and the air pressure is used to push the piston of the cylinder 5 to move to achieve coordinated work; specifically, when the electromagnetic coil of the solenoid valve 4 is energized, the electromagnetic force will push the valve core, thereby squeezing the internal spring, and then the air pressure pushes the piston of the cylinder 5 to move.

[0031] As an important implementation method, the position sensor 7 is installed on one side of the cylinder 5 and connected to the electronic counter 8. The position sensor 7 senses the position of the cylinder 5, converts the sensing signal into an electrical signal and transmits it to the electronic counter 8. The electronic counter 8 displays the electrical signal transmitted by the position sensor 7 in the form of an electronic digital signal, and records and saves the number of times the rocker switch 6 is opened and closed. When the electronic counter counts to a specified number of times, the rocker switch 6 has no abnormality, and the reliability of the rocker switch 6 is determined to be qualified. Otherwise, the reliability of the rocker switch 6 is determined to be unqualified.

[0032] In this embodiment, the indicator light 9 is located between the rocker switch 6 and the load 10, and is connected in series with the rocker switch 6 and the load 10. The indicator light 9 can be used to intuitively judge the working status of the test system, which is convenient for troubleshooting and maintenance; at the same time, the second voltage converter 11 is respectively connected to the position sensor 7 and the electronic counter 8 to provide voltage for the position sensor 7 and the electronic counter 8 to ensure their normal operation; in addition, the load 10 is also connected to the first voltage converter 1 to form a closed loop of the system.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0034] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
