Description

Bicycle length adjustment mechanism

The invention relates to a bicycle length adjustment mechanism, and particularly relates to a mechanism which can make a movement adjustment between a seat and a relative position of a cooperating vehicle body.

As the Lohas movement is becoming more and more popular in the world, riding bicycles or as a way of exercising has become very popular. Generally speaking, bicycles can only be used for single riding, in order to allow two people to ride at the same time, so With the development of bicycles, it has become the design of the cooperative car.

However, the prior art cooperative vehicle is mainly designed as a main backbone of the vehicle through a longer main frame, and then two front and rear spaced seat cushion brackets are formed thereon, and then set on the seat cushion bracket. There is a corresponding seat for the two users to ride on the bicycle in tandem, which is different from the bicycle, and the design also causes the body of the synergy car to be reduced like a folding bicycle through structural movement. The appearance (such as shortening the length of the car body) is characterized by the fact that the design of the structure allows the car to adjust the position of the seat when only a single person is riding, so that it becomes a single rideable bicycle. It can be seen that the body of the prior art cooperative car is an obstacle in the actual implementation and development of the utility model, and the corresponding front and rear positions of the existing bicycle in the main frame and the seat cushion cannot be adjusted correspondingly, so that it is practical. Application is limited (for example, when the user's arm is too long or too short, it is desirable to adjust the distance between the seat and the faucet) At the time), based on the above shortcomings, the inventor of the present invention contemplates and designs a bicycle length adjustment mechanism, in order to improve the lack of the prior art, thereby enhancing the industrial implementation. .

In view of the above-mentioned problems, the main object of the present invention is to provide a bicycle length adjustment mechanism in order to overcome the difficulties of the prior art.

In order to achieve the above object, the technical means adopted by the present invention is to design a bicycle length adjustment mechanism, which comprises: a main frame, which is an elongated cylinder, and a set of joints at a front end; a faucet assembly corresponding to the sleeve portion of the main frame and corresponding to the socket portion; a first sleeve sleeved on the main frame and selectively slidable thereon, and the faucet assembly The first sleeve is provided with a first locking component, and the first locking component can selectively lock the first sleeve on the main frame; a rear wheel drive component is correspondingly fixedly connected to the first locking component a lower portion of the first sleeve; and a first seat cushion correspondingly disposed on the first sleeve for a rider to ride.

The rear wheel drive assembly includes a main support column, which is correspondingly fixed below the first sleeve and extends downward, and a pedal shaft is disposed at an extending end of the main support column. A foot pedal is respectively disposed at both ends, and an extension frame is further disposed on the main support column toward the rear, and a rear wheel is disposed on the extension frame, and one of the rear wheels is disposed on the extension frame Further, a driving disc corresponding to driving the rear wheel is further disposed on the shaft, and the driving disc is driven by the pedal shaft to drive the rear wheel to rotate.

The bicycle length adjustment mechanism further includes: a second sleeve sleeved on the main frame and located between the first sleeve and the faucet assembly, and the second sleeve is selectable Sliding on the main frame, and the second sleeve is provided with a second locking component, so that the second locking component can selectively lock the second sleeve on the main frame; and a second The seat cushion is correspondingly disposed on the second sleeve for the other rider to ride; and wherein the second locking component is a quick release assembly.

The faucet assembly includes at least one faucet tube, the faucet tube is correspondingly disposed at the ferrule, and a faucet member is disposed at an upper end of the faucet tube, and a front fork tube is disposed at a lower end of the faucet tube, and a front wheel is disposed at a lower end of the front fork tube; wherein the first locking component is a quick release component; wherein the main frame has a circular cross section, and the main frame is horizontally disposed, and the socket is A set of mouths.

The bicycle length adjustment mechanism of the present invention utilizes the mutual cooperation of the mechanism in design, and thus can be different from the conventional bicycle, so that the first seat cushion can be correspondingly moved corresponding to the main frame, so that if the vehicle body is not suitable When the rider's arm is long, the rider can adjust the relative position of the first seat cushion and the faucet assembly to obtain better comfort during riding. In addition, the change of the mechanism makes it possible for the bicycle to pass through. The second casing and the second seat cushion are connected with other additional components for assembly, and then the bicycle can be changed to be used as a synergy car, and in order to make the above purpose, technical features and gain after actual implementation more Bright In the following, a more detailed description will be given in conjunction with the corresponding drawings in the preferred embodiments.

The present invention will be described in conjunction with the accompanying drawings in the accompanying drawings, and the drawings The subject matter is only for the purpose of illustration and supplementary description. It is not necessarily the true proportion and precise configuration after the implementation of the present invention. Therefore, the scope and configuration relationship of the attached drawings should not be limited to the scope of patent application of the present invention. Narration.
