Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a fatigue testing machine, device and system for opening and closing a cover of a vehicle-mounted makeup mirror. Background Technique

[0002] In order to ensure good use performance of a vehicle-mounted makeup mirror, there are certain requirements for the bending fatigue strength resistance of the snap spring of the cover of the vehicle-mounted makeup mirror (the number of opening and closing times of the cover of the makeup mirror ≥ 4500 times is a qualified product). At present, manual testing is adopted in production. Manual testing is usually that an operator manually opens or closes the cover of the makeup mirror, which is not only time-consuming and laborious, but also has low efficiency. In particular, there is a problem of unstable accuracy in manual testing, such as inconsistent opening or closing speed, and incomplete opening or closing, thus affecting the final test result. Therefore, it is necessary to design a testing machine with low cost, high efficiency and accurate testing for the cover of the vehicle-mounted makeup mirror. Summary of the Invention

[0003] The purpose of the utility model is to provide a fatigue testing machine, device and system for opening and closing a cover of a vehicle-mounted makeup mirror, which has reasonable design and simple structure and can improve the testing accuracy and testing efficiency.

[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0005] A fatigue testing machine for opening and closing a cover of a vehicle-mounted makeup mirror comprises a base; a product fixing seat and an opening and closing component are arranged above the base; the opening and closing component is installed on one side of the product fixing seat through a linear motion device; the opening and closing component comprises a mounting seat and an opening pull rod and a closing pull rod arranged on the mounting seat; through holes are respectively arranged on the opening pull rod and the closing pull rod; the height where the closing pull rod is located is lower than the height where the opening pull rod is located.

[0006] In the utility model, a clamping groove matching with the mounting part of the vehicle-mounted makeup mirror cover to be tested is arranged on the product fixing seat to fix the vehicle-mounted makeup mirror cover to be tested; the linear motion device is used to drive the opening and closing component to displace, wherein the opening pull rod is used to open the vehicle-mounted makeup mirror cover, and the closing pull rod is used to close the vehicle-mounted makeup mirror cover. In actual application, a hole is drilled at one end of the vehicle-mounted makeup mirror cover to be tested far away from the mounting part, and then it is installed on the product fixing seat and placed between the opening pull rod and the closing pull rod. Conventional connecting parts such as iron wires and ropes are used to sequentially pass through the through holes on the opening pull rod, the vehicle-mounted makeup mirror cover and the closing pull rod, and at the same time, it is ensured that the opening pull rod, the vehicle-mounted makeup mirror cover and the closing pull rod are respectively fixedly connected with the connecting parts and cannot slide along the connecting parts, so that the opening pull rod and the closing pull rod can open and close the vehicle-mounted makeup mirror cover under the driving action of the linear motion device, thereby completing the test on the bending fatigue strength resistance of the snap spring of the vehicle-mounted makeup mirror cover.

[0007] Preferably, the linear motion device is a slide cylinder; the mounting base is installed on the slide of the slide cylinder.

[0008] Preferably, the mounting base, the opening lever, and the closing lever are integrated into one unit.

[0009] Preferably, the base is equipped with a protective cover to protect the fatigue testing machine for opening and closing the car cosmetic mirror cover.

[0010] Preferably, the base is provided with support legs at its bottom.

[0011] A fatigue testing device for the opening and closing of vehicle cosmetic mirror covers includes a plurality of the aforementioned fatigue testing machines for vehicle cosmetic mirror covers. The device can test multiple vehicle cosmetic mirror covers simultaneously, improving testing efficiency.

[0012] Preferably, the base of the vehicle-mounted cosmetic mirror cover opening and closing fatigue testing device is an integral structure.

[0013] Preferably, the number of the vehicle-mounted vanity mirror cover opening and closing fatigue testing machines is 2 to 10. More preferably, the number of the vehicle-mounted vanity mirror cover opening and closing fatigue testing machines is 2 to 6. The device can test 2 to 10 or 2 to 6 vehicle-mounted vanity mirror covers simultaneously, improving testing efficiency.

[0014] A fatigue testing system for the opening and closing of a vehicle-mounted vanity mirror cover includes the aforementioned fatigue testing machine for the opening and closing of a vehicle-mounted vanity mirror cover and a connector. Preferably, the connector is a wire. In practical applications, the connector can also be other conventional connectors, such as ropes, as long as they enable the vanity mirror cover under test to simultaneously connect to the opening lever and the closing lever.

[0015] As is common knowledge, this utility model also includes conventional components such as a counter, a controller, a power supply, and wires. The counter is a conventional product that can record the number of times the lid of the cosmetic mirror under test is opened and closed, and can meet the conventional requirements of automated equipment, such as a conventional electronic counter; the controller is used to control the operation of each component of this utility model, and the controller is a conventional controller, such as a programmable logic controller or a microcontroller controller, which can be implemented through conventional programming, and the specific connection method is conventional technology.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This utility model has a reasonable design and simple structure. Through the cooperation of the product fixing seat, the opening and closing component, and the linear motion device, the mirror cover to be tested is fixed. The linear motion device drives the opening and closing component to move, thereby realizing the opening and closing of the mirror cover. It can quickly and stably evaluate the bending fatigue strength of the mirror cover retaining spring, reduce the waste of manpower, and improve the accuracy of the test. Attached Figure Description
