[0019] Please refer to Figures 1-4: In this embodiment, an improved solid lower link plate structure for a motorcycle includes a bracket 1 and through holes 5. A plurality of through holes 5 are machined on the outer wall of the bracket 1. The bottoms of the through holes 5 on both the left and right sides of the bracket 1 are open. When a bolt is screwed into the inner thread from the right outside, the through holes 5 on both sides of the bracket 1 will be tightened. A notch 4 is machined on the right side of the front of the bracket 1. A steering column 6 is inserted into the inner wall of the upper through hole 5. A reinforcement structure 2 is connected above the front of the bracket 1, and a fixing structure 3 is connected to the inner wall of the notch 4.

[0020] The reinforcement structure 2 includes a curved plate 201 and a straight plate 202. The rear end face of the curved plate 201 is attached to the upper front of the bracket 1. The outer side of the curved plate 201 is fixedly connected to the end of the straight plate 202. A bolt 203 is threadedly connected to the inner wall of the straight plate 202. The bolt 203 fixes the straight plate 202 and the bracket 1. The rear of the outer wall of the bolt 203 is threadedly connected to the upper front of the bracket 1. The inner wall of the curved plate 201 is attached to the outer wall of the steering column 6. The curved plate 201 restricts the position of the protrusion on the outer wall of the steering column 6 to prevent the steering column 6 from detaching from the bracket 1. The inner sides of the two curved plates 201 are attached to each other;

[0021] By fitting the inner wall of the curved plate 201 in the reinforcement structure 2 to the outer wall of the steering column 6, and at the same time fitting the rear of the curved plate 201 and the rear of the straight plate 202 to the front of the bracket 1, then the inner sides of the two curved plates 201 are attached. Then the bolt 203 is threadedly passed through the straight plate 202 from front to rear and threadedly connected to the front of the bracket 1. By increasing the fixing area of the steering column 6 through the curved plate 201, damage at the bracket 1 and the steering column 6 can be avoided, the strength of the solid lower link plate structure of the motorcycle is improved, and the service life of the solid lower link plate structure of the motorcycle is ensured.

[0022] The fixing structure 3 includes a straight cylinder 301 and a first ring 302. The outer wall of the straight cylinder 301 is slidably connected to the inner wall of the notch 4. The straight cylinder 301 slides left and right along the inner wall of the notch 4 under force. The front end of the outer wall of the straight cylinder 301 is fixedly connected to the inner wall of the first ring 302. A second ring 303 is threadedly connected to the rear of the outer wall of the straight cylinder 301. The second ring 303 rotates forward and backward through the thread on the rear of the outer wall of the straight cylinder 301 under force. The rear end face of the first ring 302 is attached to the front of the bracket 1, and the front of the second ring 303 abuts against the rear end face of the bracket 1.

[0023] Working principle:

[0024] Installation of the solid lower link plate structure of the motorcycle and the steering column:

[0025] Insert the rear of the outer wall of the steering column 6 into the through hole 5 above the bracket 1. Then, fit the inner wall of the curved plate 201 against the outer wall of the steering column 6. At the same time, the rear of the two curved plates 201 and the rear of the straight plate 202 are fitted against the front of the bracket 1. At this time, the inner sides of the two curved plates 201 are fitted together. Then, the bolt 203 is threaded through the straight plate 202 from front to back and threadedly connected to the front of the bracket 1. By increasing the fixing area of the steering column 6 through the curved plate 201, damage can be avoided at the connection between the bracket 1 and the steering column 6.

[0026] Installation of the solid lower link plate structure of the motorcycle on the vehicle body:

[0027] Insert the through holes 5 on the left and right sides of the bracket 1 into the shock absorption structure on the motorcycle body. Then, the bolt is threaded inward from the right outside through the round hole on the outside of the bracket 1. This will tighten the through holes 5 on the left and right sides of the bracket 1 to clamp the shock absorption structure. Then, the straight cylinder 301 can slide left and right on the inner wall of the notch 4 to adjust the installation position of the straight cylinder 301. Next, the second ring 303 is rotated forward through the thread on the outer wall of the straight cylinder 301 so that the front of the second ring 303 abuts against the outer wall of the bracket 1. The position of the straight cylinder 301 is fixed by the frictional force formed between the second ring 303 and the bracket 1, which can avoid position conflicts during the connection of the straight cylinder 301.
