Abstract

The utility model relates to a bicycle frame, in particular to a shock-absorption frame of a bicycle, belonging to the technical field of bicycle frames and comprising a head tube, an upper tube, a lower tube, a middle tube, an upper fork, a lower fork, a shock absorber and a shock absorber seat, wherein one end of the shock absorber seat is connected with one end of the lower fork and the other end is fixed with one end of the shock absorber; the middle part of the shock absorber seat is hinged with the lower part of the middle tube; the other end of the shock absorber is connected with one end of the upper fork through a connecting element; the head tube, the upper tube, the lower tube and the middle tube form a front frame; the upper fork, the lower fork, the shock absorber seat, the shock absorber and the connecting element form a rear frame; the front frame and the rear frame are fixed through two connecting points; one connecting point is the hinged point between the middle part of the shock absorber seat and the lower part of the middle pipe; and the other connecting point is the hinged point between the connecting element and a fixed element fixed in the middle of the middle tube. The utility model has a unique structure and a good shock absorption effect and is particularly suitable for the shapes of a mountain bicycle, an extreme sport bicycle and the like.

Description

The automatic shock-proof vehicle frame

Technical field

The utility model relates to a kind of bicycle rack, relates in particular to a kind of automatic shock-proof vehicle frame, belongs to the bicycle rack technical field.

Background technology

Existing bicycle damping frame, between vertically fixing present pipe of its bumper and the middle pipe, although being sitting in top sensation, the people still can, come for bicycle that generally damping effect is not good, especially the mountain bike that damping is had high requirement, existing bicycle damping frame damping effect is poor, does not satisfy the requirement in current market.

The utility model content

The purpose of this utility model is for solving the problems of the technologies described above, a kind of automatic shock-proof vehicle frame being provided.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:

The automatic shock-proof vehicle frame, comprise head pipe, go up pipe, down pipe, middle pipe, go up fork, lower fork and bumper, it also comprises shock absorber bearing, shock absorber bearing one end connects lower fork one end, the other end and bumper one end are fixed, in the middle part of the shock absorber bearing also with middle pipe lower hinge; The bumper other end is connected with a described end of going up fork by attaching parts; Pipe, following pipe, middle pipe formation side arm are managed, gone up to described head, and described fork, lower fork, shock absorber bearing, bumper and the attaching parts gone up constitutes after-frame; Fix by two point of connection between side arm and the after-frame, a point of connection is the hinge-point of shock absorber bearing middle part and middle pipe bottom, and another point of connection is described attaching parts and the hinge-point that is fixed on the connecting element at middle pipe middle part.

The vibrations that produce in the cycling process are to be delivered to whole vehicle frame by trailing wheel, last fork substantially; The utility model is divided into side arm and after-frame with bicycle rack, and is hinged between the frame of front and back, and main forced section-go up fork, then be connected with lower fork, and this junction extends in the tripod by bumper.Attaching parts only has a bit and is connected with the connecting element at middle pipe middle part, so the stressed back of attaching parts turns, and is that fulcrum is delivered on the bumper with power with the hinge-point of attaching parts and connecting element; Therefore, although it is stressed the most serious to go up fork, and bumper and last fork are not direct connections, neither straight-though arrangement; But, will go up the stressed of fork dexterously and transfer on the bumper by lever-type stressed transmission; Efficiently solve the problem of existing bicycle damping effect difference.

Preferred as scenery with hills and waters transfer technical scheme, described in pipe be connected by four-way piece with following pipe.

In sum, the utlity model has following beneficial effect:

The utility model structure uniqueness, good damping effect is particularly useful for vehicles such as mountain bike, extreme sport car.

Description of drawings

Fig. 1 is the utility model structural representation;

Among the figure, 1-head pipe, the last pipe of 2-, 3-is pipe down, manages the last fork of 5-, 6-lower fork, 7-bumper, 8-shock absorber bearing, 9-attaching parts, 10-connecting element, 11-four-way piece among the 4-.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification sheets, but as long as all are subjected to the protection of patent law in claim scope of the present utility model.

As shown in Figure 1, the automatic shock-proof vehicle frame comprises a pipe (1), goes up pipe (2), manages (3), middle pipe (4) down, goes up fork (5), lower fork (6), bumper (7), shock absorber bearing (8) and four-way piece (11); Shock absorber bearing (8) one ends connect lower fork one end, and the other end and bumper (7) one ends are fixed, in the middle part of the shock absorber bearing (8) also with middle pipe (4) lower hinge; Bumper (7) other end is connected with a described end of going up fork (5) by attaching parts (9); Described head is managed (1), is gone up and manage (2), following pipe (3), middle pipe (4) formation side arm, and described going up pitched (5), lower fork (6), shock absorber bearing (8), bumper (7) and attaching parts (9) formation after-frame; Fix by two point of connection between side arm and the after-frame, a point of connection is the hinge-point of shock absorber bearing (8) middle part and middle pipe (4) bottom, and another point of connection is described attaching parts (9) and the hinge-point that is fixed on the connecting element (10) at middle pipe (4) middle part.Pipe (4) is connected by four-way piece (11) with following pipe (5) in described.
