Description

Technical Field

[0001] The utility model relates to the technical field of bicycle parts, in particular to a buffer-type anti-rotation limiting structure for a bicycle head. Background Art

[0002] When a bicycle is in motion, the rider turns the handlebars, which in turn drive the front wheel of the bicycle on the lower side to rotate around the center of the front fork through the front fork, thereby adjusting the steering of the bicycle. The speed of the lithium battery bicycle itself is getting faster and faster. During the turning process, the rider cannot effectively guarantee the turning angle of the bicycle. When the bicycle speed is too fast or the road conditions are poor, if the rider turns at too large an angle, the bicycle may easily flip over and over, causing injury to the rider. This needs to be improved. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0021] See also Figure 1-5 , this embodiment provides a technical solution: a buffer-type anti-rotation limiting structure for the front of a bicycle, comprising a front fork 1 and a buffer stop mechanism 4;

[0022] Among them, the outer upper end of the front fork 1 is rotatably connected to the head tube 2 through a bearing, the inner upper end of the front fork 1 is slidably connected to the handlebar rod 3, the outer side of the handlebar rod 3 is provided with evenly distributed locking grooves 5, the upper end of the front fork 1 is slidably connected to the locking rod 6, the locking rod 6 is installed in conjunction with the locking groove 5, a pull button 8 is provided at the left end of the locking rod 6, a spring 2 7 is provided between the pull button 8 and the front fork 1, the spring 2 7 is movably sleeved with the outer side of the locking rod 6, a guide groove 9 is provided on the outer side of the handlebar rod 3, and the upper inner wall of the front fork 1 is slidably connected to the guide groove 9 through a guide bar.

[0023] Among them, the buffer stop mechanism 4 is arranged between the front fork 1 and the head tube 2, and the buffer stop mechanism 4 includes a fixed seat 41, an arc-shaped telescopic rod 42, a spring 1 43, a buffer seat 44 and a synchronous seat 46. The fixed seat 41 is evenly arranged on the side wall of the head tube 2, and the front side of the fixed seat 41 is provided with a buffer seat 44 through the evenly distributed arc-shaped telescopic rods 42 and the spring 1 43. The spring 1 43 is movably connected with the outer end of the adjacent arc-shaped telescopic rod 42. A synchronous seat 46 is provided at the upper end of the outer side of the front fork 1, and the synchronous seat 46 is installed in cooperation with the buffer seat 44; the buffer stop mechanism 4 also includes a rubber pad 45, and the rubber pad 45 is arranged on the front side of the buffer seat 44. The arc centers of the fixed end and the telescopic end of the arc-shaped telescopic rod 42 coincide with the axis of the head tube 2. A scale groove 10 is opened at the upper end of the outer side of the front fork 1, and a scale groove 2 11 is opened on the upper side of the head tube 2. The scale groove 10 and the scale groove 2 11 are installed in cooperation.

[0024] The working principle of the utility model is as follows:

[0025] The upper end of the handlebar rod 3 is connected to the external bicycle handlebar, and the pull button 8 is toggled to drive the locking rod 6 away from the adjacent locking groove 5, thereby releasing the vertical movement limit of the handlebar rod 3, and the spring 2 7 is elastically stretched, and then the handlebar rod 3 is toggled to slide vertically along the upper end of the front fork 1, so as to adjust the height of the external bicycle handlebar according to the rider's own needs, thereby improving the riding comfort of the rider, and then the locking rod 6 is plugged into the adjacent locking groove 5 through the stretching elastic force of the spring 2 7 to fix the height adjustment of the bicycle handlebar. During the height adjustment of the bicycle handlebar, the handlebar rod 3 moves vertically along the guide bar through the guide groove 9, thereby avoiding relative rotation during the relative vertical movement between the handlebar rod 3 and the front fork 1, thereby aligning the vertical positions of the locking groove 5 and the locking rod 6, and plugging them together;

[0026] When the bicycle is traveling, when the rider drives the handlebar rod 3 to rotate to adjust the steering of the bicycle head through the bicycle handlebar, the handlebar rod 3 drives the front fork 1 to rotate through the sliding engagement between the guide groove 9 and the guide bar, and the front fork 1 drives the synchronous seat 46 to rotate. When the synchronous seat 46 rotates horizontally to a certain angle, the synchronous seat 46 contacts the corresponding buffer seat 44. As the synchronous seat 46 continues to rotate, the buffer seat 44 is compressed, and the telescopic end of the arc-shaped telescopic rod 42 and the spring 1 43 gradually shrink, thereby elastically buffering the steering of the bicycle head, and at the same time, the reverse force of the spring makes the rider feel As the turning angle of the front of the vehicle gradually increases, the resistance encountered during the steering process of the front of the vehicle also gradually increases, thereby warning the rider that the steering angle is too large, improving the steering safety of the rider during riding, and the rubber pad 45 allows the synchronous seat 46 to be in flexible contact with the corresponding buffer seat 44 to avoid extrusion and wear between the two. At the same time, when the bicycle body is straightened, the scale groove 10 and the scale groove 2 11 are vertically aligned. When the rider turns the front of the vehicle, the relative horizontal misalignment angle between the scale groove 10 and the scale groove 2 11 can be used as an auxiliary reference for the turning angle of the front of the vehicle.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
