[0021] The buckle assembly tool and the assembly method of the electronic steering column of the application will be further described below in combination with the drawings and examples.

[0022] As Figures 1-4The electronic steering column snap-fit ​​assembly fixture of the present invention includes a positioning frame 1, a pushing mechanism 2, and upper and lower clamping handles 3 and 4. The positioning frame 1 specifically includes upper and lower clamping plates 11 and 12 and two side plates 13. The upper and lower clamping plates 11 and 12 are horizontally opposite each other and connected to form an integral frame structure via the side plates 13. The opening height formed at the front end of the upper and lower clamping plates 11 and 12 is slightly larger than the thickness of the electronic steering column mounting part, allowing them to be inserted into the mounting part. A U-shaped slot 14 is also provided on the upper surface of the upper clamping plate 11 for the movement of the front end of the upper clamping handle 3. A pair of axle bracket plates 15 are also provided between the two side plates 13. Each axle bracket plate 15 has a corresponding longitudinally formed arc-shaped guide hole 16 at its front. Of course, in Figure 1 Alternatively, an arc-shaped guide hole 16 can be added to the side plate 13. A pin 17 is connected between the rear parts of the two shaft bracket plates 15. The front end of the lower clamp handle 4 is fixedly connected to the lower clamp plate 4. The lower part of the front end of the upper clamp handle 3 has a vertical connecting rod 31 located in the frame structure below the U-shaped slot hole 14. The vertical connecting rod 31 has a longitudinal waist-shaped through hole 32, which is movably inserted into the pin 17. A spring support connecting rod 5 is also connected between the upper and lower clamp handles 3 and 4. Normally, the upper clamp handle 3 is supported by the spring support connecting rod 5. When the upper clamp handle is pressed down, the spring support connecting rod 5 is used to support the upper clamp handle 4. When the clamp handle 3 is raised, its front end will cause the vertical connecting rod 31 to tilt upwards; the pushing mechanism 2 includes a swing block 21, the upper front end of which has an arc-shaped pressure plate 22 that matches the curvature of the buckle 6 and has magnetism. The swing block 21 has a pair of guide shafts 23 on both sides, each located within an arc-shaped guide hole 16. The rear end of the swing block 21 passes through a pin 17 and is movably connected to the vertical connecting rod 31. When the vertical connecting rod 31 tilts upwards, it will also cause the rear end of the swing block 21 to tilt upwards, and guided by the arc-shaped guide hole 16, the arc-shaped pressure plate 22 at the front end will move as follows: Figure 4 It rotates counterclockwise.

[0023] As an example, the upper surface of the lower clamp handle 4 has a groove 41, and the lower surface of the upper clamp handle 3 has a corresponding protrusion 33.

[0024] As one embodiment, the rear end of the swing block 21 and the vertical connecting rod 31 are connected by a hook structure or other means to form a movable connection.

[0025] As one embodiment, the swing block 21 and the arc-shaped pressure plate 22 are an integral structure, and the swing block 21 and the arc-shaped pressure plate 22 are made of the same magnetic material.

[0026] Please combine Figures 3-5 As shown, the assembly method of the electronic steering column using the snap-fit ​​assembly fixture of the present invention is as follows:

[0027] A. First, attach the back of the buckle 6 to the inner surface of the arc-shaped pressure plate 22 at the front end of the swing block 21 using magnetic attraction, and make the protrusion 7 of the buckle 6 abut against the upper surface of the arc-shaped pressure plate 22.

[0028] B. The opening of the buckle 6 is positioned to face the pin tube 8 by the opening formed at the front end of the upper and lower clamping plates 11, 12 on the electronic steering column mounting position;

[0029] C. The assembly tool is pushed forward to make the buckle 6 clamped on the pin tube 8;

[0030] D. The upper clamp handle 3 is pressed down to make the vertical connecting rod 31 upwarp, and then drive the rear end of the swing block 21 upwarp, and further drive the swing block 21 to move along the arc-shaped guide hole 16, so that the arc-shaped pressing plate 22 at the front end of the swing block 21 drives the buckle 6 to rotate, until the buckle 6 is limited to abut against the pin tube 8. The assembly tool is retracted to make the arc-shaped pressing plate 22 disengaged from the buckle 6, the upper clamp handle 3 is unloaded and reset by the spring supporting connecting rod 5.

[0031] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application, as long as the changes and variations of the above described embodiments are within the scope of the spirit of the present application, they will fall within the scope of the claims of the present application.
