Abstract

The utility model discloses a bicycle frame, which comprises a front triangular body and a rear triangular body, wherein the front triangular body is formed by a head pipe, an upper pipe, a middle pipe, a lower pipe and a five way union; the rear triangular body is formed by an upper fork, a lower fork and a channel claw; a bicycle frame main body is formed by the way that the front triangular body is connected with the rear triangular body; the head pipe, the upper pipe, the middle pipe and the lower pipe are connected through joints; and the head pipe, the upper pipe, the middle pipe and the lower pipe are tubular products which are respectively formed by a carbon fiber reinforced resin base plastic pipe in an inner layer, a mesh-shaped carbon fiber sheet in a middle layer and an anti-false-type high-strength engineering plastic coating in an outer layer. The front triangular body and the rear triangular body of the bicycle frame are connected in a gluing manner; and the front triangular body or the rear triangular body adopts a high carbon fiber pipe or an aluminum-alloy pipe, so that the whole frame is firm in structure, lighter in weight, higher in strength and low in cost, has good comprehensive property and is capable of satisfying the market demands.

Description

A kind of bicycle rack

Technical field

The utility model relates to a kind of bicycle rack, belongs to technical field of bicycles.

Background technology

Standard bicycle adopts the aluminum alloy aluminum to do, and connects and composes main body of vehicle frame by welding manner between each pipe, and it is too heavy that this aluminum alloy is made vehicle frame weight, and weld ruptures easily, is not durable; And full carbon fiber bicycle frame cost is too high, does not satisfy the market demand.

The utility model content

The utility model is in order to overcome the deficiency that prior art exists, and a kind of high strength, low weight, bicycle rack cheaply are provided.

The utility model can be achieved by taking following technical scheme:

A kind of bicycle rack, comprise by the head pipe, go up pipe, middle pipe, the following pipe and the preceding triangle body that five-way constitutes and the Vee formation body that is constituted by last fork, lower fork and ditch pawl, triangle body and Vee formation body connect into main body of vehicle frame before described, described head pipe, go up between pipe, middle pipe and the following pipe and all connect by joint, described head pipe, to go up pipe, middle pipe and following Guan Jun be to be that carbon fiber enhancement resin base is moulded pipe, the middle level is the tubing that netlike carbon fiber cloth, skin constitute for anti-false type high-strength engineering plastic coating by internal layer.

On the basis of the above, connect by the gummed mode between preceding triangle body described in the utility model and the Vee formation body.

Upward fork, lower fork and ditch pawl described in the utility model are aluminium-alloy pipe.

Joint described in the utility model is for being that to mould pipe, middle level be tubing or the aluminium-alloy pipe that netlike carbon fiber cloth, skin constitute for anti-false type high-strength engineering plastic coating to carbon fiber enhancement resin base by internal layer.

Compared with prior art, the beneficial effects of the utility model are: the preceding trigonometric sum Vee formation of bicycle rack of the present utility model is formed by connecting by gummed, preceding triangle or Vee formation adopt high carbon fiber pipe or aluminium-alloy pipe, make whole body frame structure for automotive firmly, lighter weight, intensity be higher, and cost is low, have good comprehensive performances, satisfy market demand.

Description of drawings

Fig. 1 is the structural representation of bicycle rack of the present utility model;

Fig. 2 is the pipe structure scheme drawing of the main body of vehicle frame among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail.

As Fig. 1, shown in Figure 2, bicycle rack in the present embodiment comprises by head pipe 11, last pipe 12, middle pipe 13, manage 14 and the preceding triangle body 1 that constitutes of five-way 15 and by last fork 21 down, the Vee formation body 2 that lower fork 22 and ditch pawl 23 constitute, triangle body 1 and Vee formation body 2 connect into main body of vehicle frame before described, described head pipe 11, last pipe 12, all connect by joint 16 between middle pipe 13 and the following pipe 14, described head pipe 11, last pipe 12, middle pipe 13 and following pipe 14 are all for moulding pipe by internal layer 4 for carbon fiber enhancement resin base, middle level 5 is netlike carbon fiber cloth, outer 6 is the tubing that anti-false type high-strength engineering plastic coating constitutes, the described fork 21 of going up, lower fork 22 and ditch pawl 23 are aluminium-alloy pipe, wherein, connect by the gummed mode between described preceding triangle body 1 and the Vee formation body 2.As required, the material of preceding triangle body 1 and Vee formation body 2 can exchange.

In the present embodiment, described joint 16 is for being that carbon fiber enhancement resin base is moulded pipe, the middle level is tubing or the aluminium-alloy pipe that netlike carbon fiber cloth, skin constitute for anti-false type high-strength engineering plastic coating by internal layer.

The above person of thought, it only is the preferred embodiment of the utility model, when the scope that can not limit the utility model enforcement with this, namely the content of putting down in writing according to the utility model claim and utility model specification sheets has generally been done the simple equivalent variation and has been modified, and all still belongs within the utility model claim institute covering scope.In addition, summary part and title only are the usefulness of auxiliary patent document search, are not the interest field that limits the utility model.

Claims

1. bicycle rack, it is characterized in that comprising by the head pipe, go up pipe, middle pipe, the following pipe and the preceding triangle body that five-way constitutes and the Vee formation body that is constituted by last fork, lower fork and ditch pawl, triangle body and Vee formation body connect into main body of vehicle frame before described, described head pipe, go up between pipe, middle pipe and the following pipe and all connect by joint, described head pipe, to go up pipe, middle pipe and following Guan Jun be to be that carbon fiber enhancement resin base is moulded pipe, the middle level is the tubing that netlike carbon fiber cloth, skin constitute for anti-false type high-strength engineering plastic coating by internal layer.

2. bicycle rack according to claim 1 is characterized in that connecting by the gummed mode between described preceding triangle body and the Vee formation body.
