DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0020] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 3 shown, an assembly structure of an automotive magnetic switch provided by an embodiment of the present invention includes a magnetic switch 1 and two mounting ears 2. The two mounting ears 2 are respectively fixedly connected to the front and rear sides of the magnetic switch 1. A cavity 3 is formed inside the mounting ear 2. A positioning mechanism 4 is arranged inside the cavity 3, and both ends of the positioning mechanism 4 penetrate and extend out of the surface of the mounting ear 2. An adjusting mechanism 5 that cooperates with the positioning mechanism 4 is arranged inside the cavity 3, and the top of the adjusting mechanism 5 penetrates and extends out of the surface of the mounting ear 2.

[0022] Refer toFigure 3 , the positioning mechanism 4 includes a compression spring 401, two concave blocks 402, two insertion rods 403 and two connecting columns 404. The two concave blocks 402 are respectively fixedly connected to both ends of the compression spring 401. The two insertion rods 403 are respectively fixedly connected to the sides of the two concave blocks 402 away from each other. And the side of the insertion rod 403 away from the concave block 402 penetrates and extends out of the surface of the mounting ear 2. The two connecting columns 404 are respectively fixedly connected to the tops of the two insertion rods 403. The connecting column 404 is used in cooperation with the adjusting mechanism 5.

[0023] With the above solution: By setting the positioning mechanism 4, it can be assembled with a specified position through the fixing ear, thus completing the assembly.

[0024] Reference Figure 3 , the adjusting mechanism 5 includes a pulling rod 501, a moving plate 502, two pushing columns 503, two cylinders 504 and two connecting rods 505. The pulling rod 501 is fixedly connected to the middle of the top of the moving plate 502. And the top of the pulling rod 501 penetrates and extends out of the top of the mounting ear 2. The two pushing columns 503 are respectively fixedly connected to the left and right sides of the bottom of the moving plate 502. The two cylinders 504 are respectively fixedly connected to both sides inside the cavity 3. The two connecting rods 505 are respectively rotatably connected to the surfaces of the two cylinders 504. And the side of the connecting rod 505 close to the connecting column 404 is sleeved on the surface of the connecting column 404. The two pushing columns 503 are respectively located on the sides of the two connecting rods 505 away from each other. And the pushing column 503 is in contact with the surface of the connecting rod 505.

[0025] With the above solution: By setting the adjusting mechanism 5, it can drive the positioning mechanism 4 to move through the pulling of the user, so as to install the automotive magnetic switch 1.

[0026] Reference Figure 3 , a transmission hole 6 is formed on the surface of the connecting rod 505. The inner wall of the transmission hole 6 is in contact with the surface of the connecting column 404.

[0027] With the above solution: By setting the transmission hole 6, the connecting rod 505 and the connecting column 404 can be connected. Then, the connecting column 404 can be driven to move through the movement of the connecting rod 505.

[0028] Reference Figure 3 , a limiting rod 7 is fixedly connected to the inner wall of the cavity 3. And both ends of the limiting rod 7 penetrate the surfaces of the two concave blocks 402 respectively and are fixedly connected to the inner wall of the cavity 3. The concave block 402 is slidably connected to the surface of the limiting rod 7.

[0029] With the above solution: By setting the limiting rod 7, the movement of the two concave blocks 402 can be restricted, avoiding the offset and inclination of the concave blocks 402 during movement.

[0030] Reference Figure 3 On one side of the inner wall of the cavity 3 close to the magnetic switch 1, a support plate 8 is fixedly connected, and on the side of the support plate 8 close to the moving plate 502, it penetrates and extends out of the surface of the moving plate 502, and the moving plate 502 is slidably connected to the surface of the support plate 8.

[0031] With the above solution: By setting the support plate 8, the movement of the moving plate 502 can be supported and its moving direction can be restricted.

[0032] Reference Figure 3 In the middle of the bottom of the moving plate 502, a connecting block 9 is fixedly connected. On the side of the connecting block 9 close to the magnetic switch 1, a tension spring 10 is fixedly connected, and the other end of the tension spring 10 is fixedly connected to the inner wall of the cavity 3.

[0033] With the above solution: By setting the connecting block 9 and the tension spring 10, when the moving plate 502 moves, the connecting block 9 can be driven to move, then the tension spring 10 can be stretched, and then the connecting block 9 can be driven to move in the reverse direction by the pulling force of the tension spring 10.

[0034] The working principle of the present utility model:

[0035] During use, the pulling rod 501 is pulled to the side away from the magnetic switch 1. When the pulling rod 501 moves, it drives the moving plate 502 and the two pushing columns 503 to move. Then, through the movement of the two pushing columns 503, the surfaces of the two connecting rods 505 are squeezed, so that the two connecting rods 505 rotate around the cylinder 504 as the axis. When the two connecting rods 505 rotate, the inner wall of the transmission hole 6 squeezes the surface of the connecting column 404, so as to drive the connecting column 404 to move towards the side close to each other. The movement of the connecting column 404 drives the insertion rod 403 to enter the cavity 3, and drives the concave block 402 to move while squeezing the compression spring 401. At this time, the magnetic switch 1 can be installed at the designated position, and then the pulling rod 501 is pulled in the reverse direction. The return force of the compression spring 401 drives the insertion rod 403 to fix the designated position, thus completing the fixation of the magnetic switch 1.

[0036] In summary: For the assembly structure of the automotive magnetic switch, by the combined use of the magnetic switch 1, mounting ear 2, cavity 3, positioning mechanism 4, compression spring 401, concave block 402, insertion rod 403, connecting column 404, adjustment mechanism 5, pulling rod 501, moving plate 502, pushing column 503, cylinder 504, connecting rod 505, transmission hole 6, limiting rod 7, support plate 8, connecting block 9 and tension spring 10, it solves the problem that unstable installation may cause poor contact at the connection between the magnetic switch and the circuit, thereby triggering circuit faults, which may cause the circuit to be intermittently connected and affect the normal operation of related systems.
