[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-3 This utility model provides a vehicle-mounted magnetic device testing mechanism, including a workbench 1. A sliding opening 2 is provided in the middle of the upper surface of the workbench 1. An I-shaped support platform 3 is slidably connected in the sliding opening 2. A magnetic platform 4 for placing devices is bonded to the upper surface of the support platform 3. A fixing plate 11 is fixedly connected to the lower surface of the workbench 1 by bolts at one of the short sides of the sliding opening 2. Two symmetrical sliding rods 12 are slidably connected through the fixing plate 11. One end of the two sliding rods 12 is fixedly connected to a connecting plate 13 by bolts. Two symmetrical springs 14 are welded between one side of the connecting plate 13 and the fixing plate 11. A speed detector 9 is provided on the upper surface of the workbench 1 to detect the sliding speed of the support platform 3. The speed detector 9 is a DH-SA type AC220V. Side brackets are fixedly connected to the four corners of the lower surface of the workbench 1 by bolts. The side brackets are of an L-shaped structure.

[0022] It should be noted that the speed detector 9 is existing technology. After the speed detector 9 is connected to the AC 220V power supply, it enters a 10-second delay start-up stage. During this time, the working indicator light is always on, but the relay does not operate. It only displays the real-time speed and does not perform logical judgment. The mechanical motion of the object is converted into a measurable electrical signal, and then the speed value is calculated. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0023] Specifically, when testing vehicle-mounted magnetic devices, the vehicle-mounted magnetic device to be tested is first placed on the magnetic table 4 on the support platform 3 and magnetically attracted. Then, the support platform 3 is pulled to move closer to the L-shaped card plate 8. During the movement of the support platform 3, the L-shaped card plate 8 is simultaneously pulled to rotate upward. After the support platform 3 moves and contacts the connecting plate 13, the spring 14 is squeezed and compressed. Then, the L-shaped card plate 8 is embedded into one of the grooves 6.

[0024] By providing a magnetic platform 4, a connecting plate 13, and a spring 14 on the support platform 3, the stability of the on-board magnetic device in the car during sudden acceleration can be simulated, thereby detecting the stability of the on-board magnetic device under sudden acceleration.

[0025] In this utility model, a raised plate 5 is fixedly connected to one side of the support platform 3 by bolts. A groove 6 is provided on the upper surface of the raised plate 5. A concave plate 7 is fixedly connected to the upper surface of the workbench 1 and located on one of the short sides of the slide 2 by bolts. An L-shaped clamping plate 8 that cooperates with the groove 6 is rotatably connected between the inner walls of the two sides of the concave plate 7.

[0026] Furthermore, the grooves 6 are multiple grooves with equal spacing.

[0027] Specifically, the L-shaped card plate 8 is embedded into different grooves 6 to simulate the stability of the device on the magnetic table 4 under different starting speeds and deceleration speeds on the support stage 3.

[0028] The multiple grooves 6 on the protruding plate 5 can simulate the stability of the on-board magnetic device in the car under different initial speeds, and can detect the stability of the on-board magnetic device in the car under different initial speeds.

[0029] In this utility model, a fixing plate 15 is fixedly connected to the lower surface of the workbench 1 and to the other short side of the slide 2 by bolts. Two sliding rods 16 are slidably connected through the fixing plate 15. One end of the two sliding rods 16 is fixedly connected to a connecting plate 17 by bolts. Two symmetrical springs 18 are welded between one side of the connecting plate 17 and the fixing plate 15.

[0030] Specifically, the L-shaped plate 8 is embedded into one of the grooves 6, and then the L-shaped plate 8 is pulled upwards until it is no longer in contact with the groove 6. After that, the spring 14 releases its elastic force and pushes the support platform 3 to slide quickly along the slide 2 through the connecting plate 13, thereby simulating the process of a car starting quickly and testing the stability of the device. When the support platform 3 contacts the connecting plate 17, the spring 18 quickly releases the force, simulating the situation of a car braking suddenly, thereby testing the stability of the device again.

[0031] The worktable 1 has guide rails 10 on its upper and lower surfaces and on both sides of the long side of the slide 2. The inner walls of the top and bottom of the slots on both sides of the bearing platform 3 have multiple spherical grooves 19 with the same spacing. The multiple spherical grooves 19 are rotatably connected with ball bearings 20 that cooperate with the guide rails 10.

[0032] By using the ball bearing 20 and guide rail 20 together, the friction force when the support platform 3 slides along the slide 2 can be reduced, thus closely mimicking the impact of the car's movement on the on-board magnetic devices in real-world conditions.

[0033] Furthermore, the upper surface of the support platform 3 is provided with a square-shaped enclosure net 21 to block the device.

[0034] The use of this utility model involves the following steps:

[0035] S1: When testing the vehicle-mounted magnetic device, first place the vehicle-mounted magnetic device to be tested on the magnetic table 4 on the support platform 3 for magnetic attraction. Then pull the support platform 3 to move closer to the L-shaped card plate 8. During the movement of the support platform 3, pull the L-shaped card plate 8 to rotate upward. After the support platform 3 moves and contacts the connecting plate 13, squeeze the spring 14 to compress the spring 14. Then embed the L-shaped card plate 8 into one of the grooves 6.

[0036] S2: After the L-shaped plate 8 is embedded into one of the grooves 6, and then the L-shaped plate 8 is pulled upward to disengage from the groove 6, the spring 14 releases its elastic force and pushes the support platform 3 to slide quickly along the slide 2 through the connecting plate 13, thereby simulating the process of a car starting quickly and testing the stability of the device. When the support platform 3 contacts the connecting plate 2 17, the spring 2 18 quickly releases the force, simulating the situation of a car braking suddenly, thereby testing the stability of the device again.

[0037] S3: The L-shaped card plate 8 is embedded into different grooves 6 to simulate the stability of the device on the magnetic stage 4 under different starting speeds and deceleration speeds.

[0038] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0039] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
