Abstract
The utility model relates to a folded bicycle frame, particularly relates to the folded bicycle frame having a damping function. The folded bicycle frame having the damping function comprises a front fork sleeve, a saddle casing pipe, a central shaft casing pipe and a rear shaft yoke; a vertical beam is arranged at the lower end of the saddle casing pipe; the vertical beam is connected with the front fork sleeve through an upper beam; the upper beam is provided with a bending front section and a bending rear section which are connected through a folder; a connecting beam is vertically arranged on the rear section of the upper beam; the rear shaft yoke is an arc-shaped rear shaft connecting frame; the front end of the arc-shaped rear shaft connecting frame is connected with the lower end of the connecting beam through a hinged shaft; the middle of the arc-shaped rear shaft connecting frame is connected with the vertical beam through a damping spring; the bicycle safety and comfort are improved due to the fact the vibration is absorbed through deformations of the bicycle frame.
Description
Technical field
The utility model relates to a kind of folding bicycle frame, relates in particular to a kind of folding bicycle frame with shock-absorbing function.
Background technology
In prior art, the vehicle frame of bicycle generally comprises for the front fork sleeve of front fork is installed, for the saddle sleeve pipe of saddle is installed, for the axis sleeve pipe of axis is installed, between front fork sleeve and saddle sleeve pipe, by upper beam, connect, between axis sleeve pipe and front fork sleeve, by cant beam, connect, and by vertical beam, be connected between saddle sleeve pipe and axis sleeve pipe, also establish in addition for the rear axle crotch of trailing wheel is installed, rear axle crotch one end is used for installing rear axle, the other end is fixedly connected with axis sleeve pipe, existing folding bicycle is that upper beam is divided into two sections, and centre connects by folder.
But in prior art, because rear axle crotch is fixedly connected with axis sleeve pipe, make the bicycle rack on the whole cannot deformation and absorb jolting in driving process, when pavement conditions is bad, easily cause the fatigue that user is too early, affect safety traffic and comfort level.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of with shock-absorbing function and the less folding bicycle frame of bodywork length.
The utility model is to be achieved by the following technical programs:
A kind of folding bicycle frame with shock-absorbing function, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam is connected with front fork sleeve by upper beam, described upper beam is divided into two sections of the front and back of bending, at bending part, by folder, connect, described upper beam back segment is vertically provided with tie-beam, described rear axle crotch is shaft holder after arc, after described arc, shaft holder front end is hinged by the lower end of hinge and tie-beam, and after described arc, shaft holder middle part is connected by damping spring with vertical beam.
The beneficial effects of the utility model are:
Because described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam is connected with front fork sleeve by upper beam, described upper beam is divided into two sections of the front and back of bending, at bending part, by folder, connect, described upper beam back segment is vertically provided with tie-beam, described rear axle crotch is shaft holder after arc, after described arc, shaft holder front end is hinged by the lower end of hinge and tie-beam, after described arc, shaft holder middle part is connected by damping spring with vertical beam, deformation by bicycle rack carrys out absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1. front fork sleeve, 2. folder, 3. upper beam, 4. vertical beam, 5. saddle sleeve pipe, 6. damping spring, 7. shaft holder after arc, 8. axis sleeve pipe, 9. hinge, 10. tie-beam.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises front fork sleeve 1, saddle sleeve pipe 5, axis sleeve pipe 8 and rear axle crotch, described saddle sleeve pipe lower end is provided with vertical beam 4, described vertical beam is connected with front fork sleeve by upper beam 3, described upper beam is divided into two sections of the front and back of bending, at bending part, by folder 2, connect, described upper beam back segment is vertically provided with tie-beam 10, described rear axle crotch is shaft holder 7 after arc, after described arc, shaft holder front end is hinged with the lower end of tie-beam by hinge 9, and after described arc, shaft holder middle part is connected by damping spring 6 with vertical beam.
Because described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam is connected with front fork sleeve by upper beam, described upper beam is divided into two sections of the front and back of bending, at bending part, by folder, connect, described upper beam back segment is vertically provided with tie-beam, described rear axle crotch is shaft holder after arc, after described arc, shaft holder front end is hinged by the lower end of hinge and tie-beam, after described arc, shaft holder middle part is connected by damping spring with vertical beam, deformation by bicycle rack carrys out absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
