Abstract
The utility model discloses an electric bicycle frame with built-in type damping devices, which comprises an upper flat fork with two parallel fork legs arranged at the lower end of the upper flat fork, two sleeves corresponding to the two parallel fork legs and two damping devices. The upper flat fork is connected with a saddle pipe. The end port of one end of each of the sleeves is equipped with a sealing ring and a guiding slide seat and the guiding slide seat is arranged at one end of the sealing ring away from the opening of the sleeve. The fork legs passing through the sealing ring are inserted into the sleeve and are in sliding contact with the guiding slide seat. One end of the sleeve without the opening is equipped with a positioning column. The two damping devices are respectively arranged on one end of the two sleeves without the opening and one end of each of the damping devices is connected with the positioning column. The other end of each of the damping devices is positioned and attached to the fork legs extending into the sleeves and passing through the sealing rings. According to the electric bicycle frame, the damping devices are hidden inside the sleeves so as to realize the better damping effect. Meanwhile, springs are prevented from the wind and the rain, so that the service life of the springs is increased.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle vehicle frame, especially, relates to a kind of shock absorption device built-in electric cycle frame.
Background technology
At present the used bumper of rack for electric motor car all is some common bumpers, and structure is not compact, and resilience is dumb, and the cost height is exposed at the surface of car, seems very not attractive in appearance, and the damping of car simultaneously also can not get better effect.
The utility model content
The purpose of this utility model provides the good Electrical Bicycle vehicle frame of the built-in damping effect of a kind of shock absorption device.
The utility model discloses a kind of shock absorption device built-in electric cycle frame, comprising: go up chain stay, it is connected with saddle pipe, and described lower end of going up chain stay includes two fork legs that be arranged in parallel; Two sleeves, it is corresponding with described two the fork legs that be arranged in parallel, be provided with seal ring and guiding slide in the port of an end of each sleeve openings, and described guiding slide is positioned at the end away from the opening of described sleeve of described seal ring, described fork leg passes described seal ring and is inserted in the described sleeve, and with the moving contact of described guiding slide, an end of the non-opening of described sleeve is provided with registration mast; Two shock absorption devices, it is arranged on the end of non-opening of described two sleeves respectively and an end and the described registration mast of described shock absorption device joins, and the other end of described shock absorption device and the described fork leg location of passing described seal ring that stretches to described sleeve inner join.
Preferably, shock absorption device built-in electric cycle frame of the present utility model, described shock absorption device is a damping spring.
Preferably, shock absorption device built-in electric cycle frame of the present utility model also comprises by chain stay under first rotating shaft and the described saddle pipe bonded assembly, and described down chain stay and the described chain stay of going up link together by second rotating shaft.
The beneficial effects of the utility model are: the utility model vehicle frame is hidden damping spring in the sleeve be arranged on fork, makes damping effect better, and effectively avoids spring to expose to wind and rain, and exposes to the sun and rain raising spring service life.Vehicle frame cost cost of the present utility model is low, attractive and durable simultaneously.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification sheets literal to make those skilled in the art.
As depicted in figs. 1 and 2, Electrical Bicycle vehicle frame of the present utility model comprise with saddle pipe 7 bonded assemblys on chain stay 9, the lower end of last chain stay 9 includes two fork legs 8 that be arranged in parallel.This vehicle frame also comprises two sleeves that be arranged in parallel 1, and sleeve 1 is corresponding with described two the fork legs 8 that be arranged in parallel, and above-mentioned two fork legs 8 are inserted into the inside of two sleeves 1 respectively, and are inserted into an end of the opening of two sleeves 1.One end of the non-opening of sleeve 1 is provided with registration mast 3, and the port of an end of the opening of sleeve 1 is provided with seal ring 4 and guiding slide 5, and guiding slide 5 is positioned at the end away from the opening of sleeve 1 of seal ring 4.Fork leg 8 passes seal ring 4 and and described guiding slide 5 moving contacts.
Two shock absorption devices, be preferably damping spring, damping spring 2 is separately positioned on an end of the non-opening of sleeve 1, and an end of described damping spring 2 and registration mast 3 join, the other end of damping spring 2 and stretch to fork leg 8 location that sleeve 1 in-to-in passes seal ring 4 and join.
As shown in Figure 2, vehicle frame of the present utility model also comprises by chain stay 10 under first rotating shaft 6 and saddle pipe 7 bonded assemblys, and upward chain stay 9 links together by second rotating shaft 11 with following chain stay 10.
Learn through test of many times: the weight that a kind of shock absorption device built-in electric cycle frame carrying of the present utility model is 150 kilograms, shaken 210,000 times, the bumper resilience is still fine, and each several part is not out of shape fracture.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification sheets and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
