Abstract
The utility model discloses a novel bicycle tractor shock absorption device; two rear wheels are arranged at both lower ends of a supporting walking element, and both upper ends of the supporting walking element are fixedly connected with the lower ends of two connection rods, and upper ends of the two connection rods are respectively connected with the upper end of two shock absorbers in a pivot way to form a first pivot point, and the lower ends of the two shock absorbers are respectively connected with a corresponding frame in a pivot way to form a second pivot point, and the lower sides of the two connection rods are respectively connected with the corresponding frame in a pivot way to form a third pivot point; and based on the driving direction, the third pivot point is arranged behind the second pivot point. When in use, the rear wheels are stressed, the supporting walking element that is connected with the rear wheels rotates through a first coupling shaft, a second coupling shaft and a third coupling shaft; and moreover, both of the shock absorbers have the shock absorption effect, thereby realizing the shock absorption effect of the bicycle tractor during the driving process. The device has simple structure, and can obviously increase the shock absorption effect of the bicycle tractor during the driving process, and is stable and safe to drive, thereby preventing the discomfort of the human body that is brought by the shock of the bicycle tractor.
Description
Technical field
The utility model relates to a kind of trailers shock absorption device.
Background technology
Not only doing walking-replacing tool by bike in American-European countries, the important utensil of amusement and recreation and motion wherein drags the trailers behind bicycle especially, and is very in fashion especially in recent years.Trailers can be used for manned or pet.
Trailers all is the design that does not possess shock-absorbing function generally, and the vibrations that trailers travels when taking like this bring human discomfort can for human body or pet.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of new bicycle trailer shock absorption device, and this new bicycle trailer shock absorption device can obviously increase trailers damping effect in the process of moving, driving stability safety, ride comfort.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of new bicycle trailer shock absorption device, comprise unitized frame, two bumpers, about two rear wheels, two rear wheels are located at and are supported walking part downside two ends, support walking part upside two ends and be fixed in two pipe link lower ends, two pipe links upper end is articulated in two bumpers upper end respectively and forms first pivoting point, two bumper lower ends are articulated in corresponding vehicle frame respectively and form second pivoting point, two pipe link downsides are articulated in corresponding vehicle frame respectively and form the 3rd pivoting point, be as the criterion with travel direction, described the 3rd pivoting point is in the back of described second pivoting point.
Vehicle frame is provided with frame reinforcement spare, and two bumper lower ends are articulated in vehicle frame and the frame reinforcement spare respectively.
Two pipe links upper end is respectively equipped with two bumper attaching partss, and two bumper attaching partss are articulated in two bumpers upper end respectively.
Two bumper lower ends are articulated in vehicle frame and the frame reinforcement spare by second coupling spindle respectively.
Two bumper attaching partss are articulated in two bumpers upper end by the 3rd coupling spindle respectively, and two pipe link downsides are articulated in corresponding vehicle frame by first coupling spindle respectively.
Two bumpers are oblique state.
Two bumpers are spring damping formula bumper.
The beneficial effects of the utility model are: this routine use is: when trailers normally uses, rear wheel is stressed, the support walking part that connects rear wheel is stressed, by first, two, three coupling spindles rotate, can rotate relative to vehicle frame as two pipe link downsides, two pipe links upper end can be rotated relative to two bumpers upper end, two bumper lower ends can be distinguished relative to vehicle frame and rotate, the own tool damping effect of two bumpers again, thereby reached trailers damping effect in the process of moving, therefrom this example is simple in structure as can be seen, can obviously increase trailers damping effect in the process of moving, driving stability safety, thereby the human discomfort of effectively having avoided trailers to bring to human body because of the vibrations of travelling.

The specific embodiment
Embodiment: a kind of new bicycle trailer shock absorption device, comprise unitized frame 1, two bumpers 2, about two rear wheels 3, two rear wheels are located at and are supported walking part 4 downside two ends, support walking part upside two ends and be fixed in two pipe links, 5 lower ends, two pipe links upper end is articulated in two bumpers upper end respectively and forms first pivoting point, two bumper lower ends are articulated in corresponding vehicle frame respectively and form second pivoting point, two pipe link downsides are articulated in corresponding vehicle frame respectively and form the 3rd pivoting point, be as the criterion with travel direction, described the 3rd pivoting point is in the back of described second pivoting point.
Vehicle frame is provided with frame reinforcement spare 6, two bumper lower ends and is articulated in respectively in vehicle frame 1 and the frame reinforcement spare.
Two pipe links upper end is respectively equipped with two bumper attaching partss, 11, two bumper attaching partss and is articulated in two bumpers upper end respectively.
Two bumper lower ends are articulated in vehicle frame and the frame reinforcement spare by second coupling spindle 9 respectively.
Two bumper attaching partss are articulated in two bumpers upper end by first coupling spindle 8 respectively, and two pipe links, 5 downsides are articulated in corresponding vehicle frame by the 3rd coupling spindle 10 respectively.
Two bumpers are oblique state.
Two bumpers are spring damping formula bumper.
This routine course of action is: when trailers normally uses, rear wheel is stressed, the support walking part that connects rear wheel is 4 stressed, rotate by first, second and third coupling spindle 8,9,10, can rotate relative to vehicle frame 1 as two pipe links, 5 downsides, two pipe links, 5 upper ends can be rotated relative to two bumpers, 2 upper ends, two bumper lower ends can be distinguished relative to vehicle frame and rotate, the own tool damping effect of two bumpers again, thus reached trailers damping effect in the process of moving.
