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; one side of the vertical beam is provided with an upper beam; an inclined beam is arranged on one side of the front fork sleeve; the inclined beam is provided with two sections which are connected through a folder; the rear section of the inclined beam is connected with the upper beam; the central shaft casing pipe which is arranged at the front end of the rear shaft yoke is hinged to the rear end of the inclined beam through a hinged shaft; a connecting frame is arranged on the other side of the vertical beam; the connecting frame is connected with the lower portion of the rear shaft yoke through a damping spring. According to the folded bicycle frame having the damping function, the bicycle safety and comfort are improved due to the fact that the vibration is absorbed through deformation of the bicycle frame and the strength of the frame is effectively reinforced due to the fact that the cross section of the inclined beam is in a rectangular shape.
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, and a kind of folding bicycle frame with shock-absorbing function is provided.
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 one side is provided with upper beam, described front fork sleeve one side is provided with cant beam, described cant beam is divided into two sections, centre connects by folder, the back segment of described cant beam is connected with upper beam, described axis sleeve pipe is located at rear axle crotch front end, and hinged by hinge and cant beam rear end, the opposite side of described vertical beam is provided with link span, and described link span is connected by damping spring with rear axle crotch bottom.
Described cant beam cross-sectional plane is rectangle.
The beneficial effects of the utility model are:
Because described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam one side is provided with upper beam, described front fork sleeve one side is provided with cant beam, described cant beam is divided into two sections, centre connects by folder, the back segment of described cant beam is connected with upper beam, described axis sleeve pipe is located at rear axle crotch front end, and hinged by hinge and cant beam rear end, the opposite side of described vertical beam is provided with link span, described link span is connected by damping spring with rear axle crotch bottom, and the deformation by bicycle rack carrys out absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle; And cant beam cross-sectional plane is rectangle, more enough actvies are strengthened the intensity of vehicle frame.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1. front fork sleeve, 2. cant beam, 3. hinge, 4. axis sleeve pipe, 5. damping spring, 6. rear axle crotch, 7. link span, 8. vertical beam, 9. saddle sleeve pipe, 10. upper beam, 11. folder.
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 9, axis sleeve pipe 4 and rear axle crotch 6, described saddle sleeve pipe lower end is provided with vertical beam 8, described vertical beam one side is provided with upper beam 10, described front fork sleeve one side is provided with cant beam 2, described cant beam is divided into two sections, centre connects by folder 11, the back segment of described cant beam is connected with upper beam, described axis sleeve pipe is located at rear axle crotch front end, and hinged by hinge 3 and cant beam rear end, the opposite side of described vertical beam is provided with link span 7, and described link span is connected by damping spring 5 with rear axle crotch bottom.
Because described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam one side is provided with upper beam, described front fork sleeve one side is provided with cant beam, described cant beam is divided into two sections, centre connects by folder, the back segment of described cant beam is connected with upper beam, described axis sleeve pipe is located at rear axle crotch front end, and hinged by hinge and cant beam rear end, the opposite side of described vertical beam is provided with link span, described link span is connected by damping spring with rear axle crotch bottom, and the deformation by bicycle rack carrys out absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle; And cant beam cross-sectional plane is rectangle, more enough actvies are strengthened the intensity of vehicle frame.
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.
