Abstract
The utility model discloses an electric bicycle frame adopting a curved fitting connection mode. The electric bicycle frame comprises a double curved fitting, a saddle pipe, a shock absorber and a bottom fork, wherein the upper end of the double curved fitting is connected with the rear end of the shock absorber; the lower end of the double curved fitting is connected with a connecting rod through a rotating shaft arranged on the double curved fitting; the saddle pipe is perpendicularly connected to a girder, and the saddle pipe, the girder and the connecting rod form a triangular shape in general; the front end of the shock absorber is connected with a first support tube, and the first support tube and the center of the shock absorber form a straight line; and the bottom fork is connected with the upper end of the double curved fitting, two second support tubes are arranged below the bottom fork, the two second support tubes are connected with the middle of the double curved fitting, and the two support tubes extend to the rear end of the electric bicycle frame so as to form a triangular shape in general. The electric bicycle frame provided by the utility model has the advantages of simple structure and fatigue resistance, and is stronger in performance when driving on a bumpy road. The electric bicycle frame provided by the utility model utilizes a lever structure so as to enable the damping effect to be better.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle vehicle frame, especially, relates to a kind of bent attached Electrical Bicycle vehicle frame that connects mode that uses.
Background technology
The Electrical Bicycle of existing market is simple in structure because of vehicle frame, causes insufficient strength, thereby makes Electrical Bicycle can not get damping effect preferably, brings inconvenience to use.And the chassis structure complexity of prior art does not have better shock-proof effect on the road of jolting.Therefore, there is a kind of demand to Electrical Bicycle vehicle frame with good damping effect.
The utility model content
The purpose of this utility model is to provide a kind of Electrical Bicycle vehicle frame with good shock-absorbing function, and it connects by the attached mode that connects of song.
For the dynamic property of this vehicle carriage structure better, the technical scheme that its technical matters that solves the utility model the utility model adopts is: saddle pipe and crossbeam constitute triangle, Vee formation has big bent tag, bent attached upper end and bumper rear end links together, the front end of bumper be connected with preceding triangle support tube, pipe constitutes straight line with the bumper center, there are the same three corner connections of a rotating shaft lower end of bent tag, two support tubes and bent attached connecing are arranged under the Vee formation chain stay, extend back, intersection constitutes little triangle, and the two ends of damping and rotating shaft center constitute straight line, become triangle.
The utility model discloses a kind of bent attached Electrical Bicycle vehicle frame that connects mode that uses, comprising: hyperbolic is attached, and its upper end is connected with the rear end of bumper, and the attached lower end of described hyperbolic is connected with connecting rod by the rotating shaft that is arranged on described hyperbolic and encloses; Saddle pipe, it vertically is connected with crossbeam, and described saddle pipe and described crossbeam and described connecting rod formation triangle substantially; Bumper, its front end is connected with first support tube, and the center of described first support tube and described bumper forms straight line; Chain stay, it is connected with the attached upper end of described hyperbolic, and be provided with two second support tubes below the described chain stay, and described two second support tubes are connected with the attached middle part of described hyperbolic, described two second support tubes extend to form substantially triangle to the vehicle frame rear portion.
The beneficial effects of the utility model are: the utility model chassis structure is simple and easy, and antifatigue is travelled on the road of jolting, and performance is stronger.The utility model utilizes lever construction to make damping effect better, and is better.
Description of drawings
Fig. 1 is a front 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 shown in Figure 1, the upper end of hyperbolic of the present utility model attached 2 is connected with the rear end of bumper 3, and the lower end of hyperbolic attached 2 is connected with connecting rod by the rotating shaft 1 that is arranged on described hyperbolic and encloses; Saddle pipe 6 vertically is connected with crossbeam 5, and described saddle pipe 6 and described crossbeam 5 and described connecting rod formation triangle substantially;
The front end of bumper 3 is connected with first support tube 4, and the center of described first support tube 4 and described bumper 3 forms straight line;
Like this, when Electrical Bicycle meets obstruction, resistance can pass to the preceding triangle that saddle pipe 6, crossbeam 5 and connecting rod form by first support tube 4, passes to bumper 3 again, passes to the Vee formation shape of two second support tubes, 7 formation of 8 times settings of chain stay afterwards.Thereby resistance tends to become weak gradually, makes damping effect remarkable.
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.
