Abstract

The utility model discloses a bicycle saddle with a shock-absorption backrest, which comprises a saddle pipe, two seat beams and a saddle seat cushion. The bicycle saddle is characterized in that punched holes are respectively formed at the front end and the rear end and at the middle parts of the two seat beams; the punched holes at the front ends of the two seat beams are respectively sleeved on both sides of an axle A, and the axle A is vertically fixed with the saddle pipe; the lower end of a U-shaped backrest support penetrates the punched holes at the rear ends of the two seat beams and is fixedly connected with the two seat beams, and the upper end of the U-shaped backrest support is fixedly connected with the backrest; a piston and a piston cavity are arranged in a space formed by the lower part of the saddle seat cushion, the two seat beams, the axle A and the lower end of the U-shaped backrest support; a spring is sleeved in the piston cavity, and sliding chutes are arranged on both sides of the piston cavity; and the piston is fixedly connected with an axle B, and the axle B penetrates the punched holes at the middle parts of the two seat beams. The utility model achieves the purpose of shock absorption through the linkage of the U-shaped backrest support and the seat beams as well as the return motion of the spring in the piston cavity.

Description

Damping backrest bicycle saddle

Technical field

The utility model relates to a kind of bicycle saddle; Especially a kind of damping backrest bicycle saddle.

Background technology

As shown in Figure 5, Chinese patent CN2223239Y discloses a kind of lady's bicycle saddle messaging backs on 02 11st, 1996, comprise messaging backs 1, strut bar 3, fixer 6 and saddle arm 5, the upper end of strut bar 3 and messaging backs 1 join, the lower end of strut bar 3 and fixer 6 join, fixer 6 matches with saddle arm 5, and fixer 6 front ends have opening folder 8, and opening folder 8 matches with saddle arm 5.

The bicycle saddle of said structure does not have shock absorption device, and backrest can not move relative to saddle, rides for a long time in the road surface that incompatibility is jolted, and the sense of user's buttocks tenderness is obvious.

The utility model content

At the above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to propose a kind of backrest bicycle saddle with shock-absorbing function.

For the technical solution problem, the damping backrest bicycle saddle that the utility model proposes comprises a saddle pipe, two seat beams and a saddle, it is characterized in that, two seat beam rear and front ends and middle part are equipped with perforation; The perforation of two seat beam front ends is set in the both sides of an A respectively, axle A and saddle pipe vertical fixing; U-shaped back bracket lower end is passed the perforation of two seat beam rear ends and is fixedly connected with two seat beams, and U-shaped back bracket upper end and backrest are fixedly connected; Saddle seat cushion bottom is provided with piston and plunger shaft in the space that two seat beams, axle A and U-shaped back bracket lower end form; Spring housing is located in the plunger shaft, and the plunger shaft both sides have chute; Piston and axle B are fixedly connected, the perforation that axle B passes two seat beam middle parts.

Compare with existing bicycle saddle with backrest, the utility model has been realized damping by the interlock and the return motion of spring in plunger shaft of U-shaped back bracket and seat beam.

Description of drawings

Fig. 1 is an integral structure scheme drawing of the present utility model.

Fig. 2 is assembling scheme drawing of the present utility model (backrest is not oppressed backward).

Fig. 3 is an assembling scheme drawing of the present utility model (backrest is oppressed backward by the user).。

Fig. 4 is the birds-eye view after the assembling of the present utility model.

Fig. 5 is the structural representation of bicycle saddle backrest in the prior art.

Among Fig. 1-4: 1 is stifle; 2 is the saddle seat cushion; 3 is axle A; 4 is saddle pipe; 5 is spring; 6 is plunger shaft; 7 is axle B; 8 is piston; 9 is the U-shaped back bracket; 10 is backrest.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further set forth the utility model.These embodiment be interpreted as only being used to illustrate utility model of the present invention and be not used in the restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.

Shown in Fig. 1-4, a kind of damping backrest bicycle saddle that the utility model one preferred embodiment proposes comprises that a saddle pipe 4, two seat beams 11 and saddle seat cushion 2, two seat beams, 11 rear and front ends and middle part are equipped with perforation; The perforation of two seat beams, 11 front ends is set in the both sides of an A3 respectively, axle A3 and saddle pipe 4 vertical fixing; U-shaped back bracket 9 lower ends are passed the perforation of two seat beams, 11 rear ends and are fixedly connected with two seat beams 11, and U-shaped back bracket 9 upper ends and backrest 10 are fixedly connected; Saddle seat cushion 2 bottoms are provided with piston 8 and plunger shaft 6 in the space that two seat beams 11, axle A and U-shaped back bracket 9 lower ends form; Spring 5 is set in the plunger shaft 6, and plunger shaft 6 both sides have chute; Piston 8 and axle B7 are fixedly connected, the perforation that axle B7 passes two seat beams, 11 middle parts, and when spring 5 was compressed, axle B7 moved downward along chute.

Also can adopt structure common in the prior art at saddle seat cushion 2 in the present embodiment, to realize the damping simultaneously of saddle seat cushion and backrest with damping.

Specify course of action of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 3, the user is sitting in when oppressing backrest 10 backward on the saddle seat cushion 2, drives U-shaped back bracket 9 and rotates along axle A3, and piston 8 moves downward under the effect of the interlock of axle B7, compression spring 5, and play the shock-absorbing effect; Backrest 10 is limited when piston 8 bottoms contact with plunger shaft 6 bottoms, and backrest 10 can not continue to rotate backward again.As shown in Figure 2, when user's forward lean, upwards reset, backrest 10 is resetted forward by axle B7 at the effect lower piston 8 of spring 5.
