Description

Steering tube for bicycle rider

This creation is related to bicycles, in particular to a driver's stem of a bicycle.

The shock-absorbing standpipe disclosed by TW M625502 forms an accommodation space between the pressing part and the main body of the handle base, and the accommodation space is used for installing a shock-absorbing element. When the rider encounters an uneven road when riding a bicycle , the front fork vertical tube will move up and down and press the pressing part against the shock-absorbing element to buffer and absorb the above-mentioned shock force. However, in the aforementioned patent case, too much space of the handle seat is not used, resulting in waste of materials.

The handle base disclosed by TW M568812 uses a pivot assembly to pivotally connect to a pivot portion of the riser base. When the handle base moves up and down relative to the riser base, it will move up and down along an arc track, causing the hands to also move along the arc. This will cause bad riding posture and affect the riding comfort. In addition, the action of the handle base along the arc-shaped track will generate lateral component force, which may cause the handle to rotate unexpectedly, resulting in riding up. danger.

In the handle device disclosed in CN 1064450A, a buffering part is arranged between the upper connecting part and the lower connecting part, and the shocking suffered by the rider during riding is absorbed by the buffering part. However, in the aforementioned patent case, because the volume of the upper and lower connectors is too large, material waste is caused.

The main purpose of this creation is to provide a bicycle driver's vertical tube, which can reduce the volume and has a shock-absorbing effect.

In order to achieve the above-mentioned main purpose, the driver's stem tube of the present invention includes a riser seat, a driver's handlebar seat, a connecting rod set, and a shock-absorbing body. The riser base is used to fix a front fork riser; the handlebar base is used to fix a handlebar; the connecting rod set has an upper link base and a lower link base, the upper link base and the lower link The seat is set up and down oppositely, the front end of the upper link seat and the front end of the lower link seat are pivotally arranged on the handlebar seat, and the rear end of the upper link seat and the rear end of the lower link seat are pivotally arranged on the stand A pipe seat, so that a covering space is formed between the riser seat, the upper connecting rod seat and the lower connecting rod seat; seat and the lower link seat, when the rear end of the upper link seat and the rear end of the lower link seat pivot relative to the riser seat, the shock-absorbing body is compressed and deformed and provides elastic restoring force.

It can be seen from the above that when the rider encounters an uneven road while riding the bicycle, the front fork riser will drive the riser seat to move up and down, and at this time, the connecting rod group will press against the riser when it shakes. The shock-absorbing body buffers and absorbs the shock force received by the front fork standpipe, so that the vibration degree of the handlebar seat and the handlebar of the driver can be reduced to a minimum, so as to effectively relieve the uncomfortable feeling of riding.
