Abstract

The utility model discloses a structure of a bicycle frame. Each pipe body of the vehicle frame is independently formed; in the pipe bodies which are connected with an adapting seat of a saddle seat, a vibration absorption elastic body is sheathed on one or more than one pipe body; each of the pipe bodies is formed on the connecting position in the modes of adhesion, reinforcement and thermosetting to form the bicycle frame. Because each of the pipe bodies of the bicycle frame of the utility model adopts independent forming, the vibration absorption elastic body can be sheathed on the pipe bodies and then the pipe bodies can be connected with each other. The bicycle frame which is formed in the mode has an integral vibration-avoiding function.

Description

Bicycle frame structure

Technical field

The utility model relates to a kind of bicycle frame structure that utilizes composite material to make.

Background technology

Traditional bicycle, in order to guarantee the whole impregnability of vehicle body, whole vehicle frame is made by metal tube, and the bicycle that this metal tube is made, vehicle body is heavy, carries inconvenience.Existing dealer is the weight that alleviates vehicle body, and whole vehicle frame adopts light weight, and the carbon fiber reinforce plastic material that intensity is high is made.

Cooperate shown in Figure 1, the vehicle frame A that this composition fiber is made is that employing is one-body molded, in the manufacturing process of vehicle frame, each manages junction when thermosetting is finalized the design, and because of the forward degree of fiber can change, and causes each junction to produce the phenomenon of stress concentration, this phenomenon is difficult for being found in detection, in use, very easily destroy herein, cause injury the user; This integrated vehicle frame A is though associative perception is strong in appearance for it, attractive in appearance; But it is bigger to make the needed mould of this vehicle frame A, and its volume is at least greater than 20% of whole vehicle frame, and the cost of manufacture height of big mould also is one of defective.

The shock wave scheme drawing that unitized frame shown in Figure 2 for another example produces vehicle seat, because the carbon fiber reinforce plastic material has light weight, advantages of high strength, thereby be widely used in voluntarily in the racing body, and the vehicle seat of racing car for adapt to ergonomics also be more establish littler, spring is set in vehicle seat realizes that incabloc function has been subjected to the restriction in space, so vehicle frame need possess incabloc function, to reduce vibrations vehicle seat, the injury that minimizing causes human body also is dealer's problem demanding prompt solution.

The utility model content

The purpose of this utility model provides a kind of bicycle frame structure that possesses incabloc function.

For achieving the above object, solution of the present utility model is: a kind of bicycle frame structure, wherein each body of this vehicle frame is independent moulding, at each body that connects the vehicle seat stacker, have to be arranged with the shock-absorbing elastic body on the one or more body, each body carries out bonding reinforcement thermoset forming again and forms a vehicle frame in junction.

All be arranged with the shock-absorbing elastic body on three bodys of described connection vehicle seat stacker.

Be formed with necking down on described each body, the shock-absorbing elastic body is to be placed in this necking down.

Described shock-absorbing elastic body can move on each body.

After adopting such scheme, the utility model is commonly used product relatively and is had the following advantages:

1, because each body of vehicle frame of the present utility model adopts independent moulding, therefore be bound up after can being nested with the shock-absorbing elastic body earlier on each body, so the vehicle frame that constitutes has incabloc function again.

2, the shock-absorbing elastic body on each body can adopt different colors and shape to increase the aesthetic property and the variety of vehicle frame.

The specific embodiment

Following structure accompanying drawing is described in further detail the specific embodiment of the present utility model.

Shown in Fig. 3,4, vehicle frame A of the present utility model is that the

body

1,2,3,4,5,6 by each independent moulding constitutes, on the

body

1,2,3 that connects the vehicle seat stacker, be equipped with shock-absorbing elastic body B respectively, each

body

1,2,3,4,5,6 junction be adopt bonding after, mend again to insert behind the yarn sheet and carry out thermoset forming in the mould and form a vehicle frame A, because of the independent moulding of each body, after then shock-absorbing elastic body B can be placed on the

body

1,2,3 respectively, each body connect again just; And carry out cementation, benefit yarn sheet, and carry out the heat fixation type in junction; And the elastic property of shock-absorbing elastic body B then can make its demand with the user on each body move its position on body.

Shown in Fig. 5,5A, during each body moulding, for making things convenient for the stationkeeping of shock-absorbing elastic body B, also can on

body

1,2,3, form necking down 11,21, see the necking down 21 shown in Fig. 5 A, owing to the incabloc function that can increase vehicle frame A that is provided with of shock-absorbing elastic body B, please as shown in Figure 6, vehicle frame A is reduced to minimum to the shock wave of vehicle seat, increases comfort by bike.

For further increasing aesthetic property and the variety of vehicle frame A, shock-absorbing elastic body B can adopt different colors and shape.

Claims

1, a kind of bicycle frame structure, it is characterized in that: each body of this vehicle frame is independent moulding, each body connecting the vehicle seat stacker has to be arranged with the shock-absorbing elastic body on the one or more body, and each body carries out bonding reinforcement thermoset forming again and forms a vehicle frame in junction.

2, bicycle frame structure as claimed in claim 1 is characterized in that: all be arranged with the shock-absorbing elastic body on three bodys of connection vehicle seat stacker.

3, bicycle frame structure as claimed in claim 1 or 2 is characterized in that: be formed with necking down on described each body, the shock-absorbing elastic body is to be placed in this necking down.
