Head bowl assembly that can limit steering angle

The present invention relates to a head bowl assembly that can be used in a steering mechanism for a bicycle, and more particularly to a head bowl assembly that can limit the steering angle.

The front bowl assembly is used to drive the front wheel to turn by the user turning the front of the vehicle. Taking a bicycle as an example, the front fork vertical pipe is relatively rotatably inserted through the front body of the vehicle through the two-head bowl assembly, and the front fork is fixed to the handle and the front wheel, so that the user can drive the front wheel relative to the body by the control handle. Deflection left and right.

There is a head bowl assembly with a steering limit function, such as the one provided in Japanese Patent No. M397345, which has a bump for the top of the bowl fixed with the front tube of the bicycle, and one for the fork with the bicycle. The bottom of the upper cover fixed by the vertical pipe has a limiting slot, so that the convex block moves from the center of the limiting slot to the two ends when the front wheel of the bicycle is deflected to the left and right, thereby limiting the head of the bicycle to the left And the angle of deflection to the right to avoid the front wheel being deflected more than 90 degrees under improper control, and can be reversed when the bicycle is accidentally dumped, and the deflection angle of the front head is too large to hit the vehicle body.

Since the front bowl assembly is fixed to the front fork and the front tube of the bicycle by friction, and some members of the front bowl assembly are fixed to each other by the friction force, when the bicycle is hit by an external force, the front In the components of the fork standpipe, the front pipe and the front bowl assembly, the two members may be mutually fixed, and the relative rotation may occur. After the above-mentioned front bowl assembly occurs, the bracket of the bowl may deviate from the upper cover when the front end is not deflected. In the center of the limit groove, the front wheel may not be able to deflect a sufficient angle in one direction, but in the other direction, the angle of deflection may be too large to avoid reverse or the front of the vehicle hitting the body. However, if the user wants to check whether the angle of the bowl and the upper cover of the front bowl assembly is appropriate, the front bowl assembly must be disassembled, which is quite inconvenient for the user and needs to be improved.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a front bowl assembly that can limit the steering angle, so that the user can easily check whether the angle of the components of the front bowl assembly is appropriate, and improve riding safety and avoid accidents. The opportunity to happen.

In order to achieve the above object, the head bowl assembly for limiting the steering angle provided by the present invention comprises a receiving bowl, a bearing, a pressing member and a covering member, the receiving bowl having an end surface and a recess recessed from the end surface The bearing is disposed in the groove, the pressing member is disposed on one side of the bearing, the covering member is disposed above the pressing member and covers the groove of the receiving bowl; the characteristics of the front bowl assembly The bowl has an outer peripheral surface, and a limiting groove recessed from the outer peripheral surface and the end surface, and the limiting groove has two limiting ends; and the covering member has a surface opposite to the end surface of the receiving bowl a cover surface and a protrusion protruding from the cover surface into the limiting slot. The receiving bowl can be disposed at one end of a front tube of one of the bicycles, and the covering member and the pressing member can be used for the front fork vertical tube of the bicycle to be fixedly disposed, so that the front fork vertical tube can be opposite The front tube rotates. According to the feature of the front bowl assembly, the protrusion can only move between the two limiting ends of the limiting slot, so the covering member and the front fork standpipe can only face the bowl And the front tube rotates within a certain angle range, and the protrusion and the limiting slot are exposed, so that the user can directly see the relative position thereof, so as to facilitate checking whether the covering member and the angle of the receiving bowl are appropriate.
