Abstract

The invention relates to a bicycle frame of an electric bicycle. The bicycle frame comprises a main bicycle frame beam, a handlebar connecting frame, a bicycle seat frame, a rear bicycle frame and a connecting and fixing rod, wherein the main bicycle frame beam is a curved beam and consists of a main beam upper segment, a main beam bent part and a main beam lower segment which are integrally formed. The middle part of the handlebar connecting frame is fixedly connected with the top part of the main beam upper segment. The bicycle seat frame is fixedly connected with the inside surface of the tail end of the main beam lower segment, The rear bicycle frame, the bicycle seat frame and the connecting and fixing rod form a triangle, and an inwardly-dished punching groove is formed in the inner side of the main beam bent part. A reinforcement support sheet is arranged on the outer side of the main beam bent part. A battery bearing plate is arranged on the surface of the inner side of the middle part of the main beam lower segment. The bicycle frame has the beneficial effects that the bicycle frame is simple in structure, and is convenient to use; and the firmness and the safety of the main beam of the electric bicycle can be effectively enhanced, so that a condition that the whole electric bicycle is scrapped since the main beam gets deformed due to external force impact is avoided . At the same time, the safety of a rider can be guaranteed.

Description

A kind of electric bicycle fame
(1) technical field
The present invention relates to a kind of vehicle frame, particularly relate to a kind of electric bicycle fame.
(2) background technology
At present, Electrical Bicycle is day by day used by increasing people, become gradually the main flow walking-replacing tool of people's trip, the vehicle frame main beam of present Electrical Bicycle is on the market all that one-time formed steel pipe is made mostly, when girder bending place is subject to external impacts, is easy to bending distortion, cause girder to scrap, thereby whole battery-driven car is scrapped, to car owner, brought very large economic loss, also can threaten to the safety of navigating mate simultaneously.The electric bicycle fame that can effectively strengthen on the market electric bicycle fame firmness degree and safety now is not also found, and has to be developed.
(3) summary of the invention
In order to overcome the weak point of existing vehicle frame, the invention provides a kind of electric bicycle fame.
Technical scheme of the present invention is to realize like this.
A kind of electric bicycle fame of this programme, comprise vehicle frame main beam, handlebar link span, Carrier for cycle, car after-frame and be connected and fixed bar, described vehicle frame main beam is camber beam, this vehicle frame main beam is comprised of integrated girder epimere, girder kink and girder hypomere, and described handlebar link span middle part is fixedly connected with girder epimere top; Described Carrier for cycle is fixedly connected with girder hypomere tail end inner surface; Described car after-frame is fixedly connected with Carrier for cycle lower surface; Described car after-frame tail end is fixedly connected with being connected and fixed bar one end, and this is connected and fixed the bar other end and is fixedly connected with Carrier for cycle upper face; Described car after-frame and Carrier for cycle and to be connected and fixed bar triangular in shape, described girder kink inner side is provided with punching press inner groovy; Described girder kink arranged outside has reinforcing supporting blade; Described girder hypomere middle part inner surface is provided with battery supporting plate.
Usefulness of the present invention is: this body frame structure for automotive is simple, easy to use, can effectively strengthen firmness degree and the safety at Electrical Bicycle girder position, thereby avoid main beam deformation under external force collision to cause the situation that Electrical Bicycle integral body is scrapped to occur, make the safety of navigating mate obtain guarantee simultaneously.
(4) accompanying drawing explanation
Fig. 1 is organizational structure schematic diagram of the present invention.
(5) specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made to brief description.
A kind of electric bicycle fame as shown in Figure 1, comprise vehicle frame main beam, handlebar link span 4, Carrier for cycle 5, car after-frame 6 and be connected and fixed bar 7, described vehicle frame main beam is camber beam, this vehicle frame main beam is comprised of integrated girder epimere 1, girder kink 2 and girder hypomere 3, and described handlebar link span 4 middle parts are fixedly connected with girder epimere 1 top; Described Carrier for cycle 5 is fixedly connected with girder hypomere 3 tail end inner surfaces; Described car after-frame 6 is fixedly connected with Carrier for cycle 5 lower surface; Described car after-frame 6 tail ends are fixedly connected with being connected and fixed bar 7 one end, and this is connected and fixed bar 7 other ends and is fixedly connected with Carrier for cycle 5 upper faces; Described car after-frame 6 and Carrier for cycle 5 and to be connected and fixed bar 7 triangular in shape, described girder kink 2 inner sides are provided with punching press inner groovy 8, the shape of this punching press inner groovy 8 plays the stressed support in inner side of strengthening girder kink 2, while making impulse force that girder kink 2 receives that outside applies, can effectively protect girder kink 2 can not be out of shape; Described girder kink 2 arranged outside have the stressed dynamics that supporting blade 9 is reinforcement girder kink 2 outsides of reinforcing, make girder kink 2 receive inner side apply power time can effectively protect girder kink 2 can not be out of shape, strengthen firmness degree and the safety at Electrical Bicycle girder position, avoided girder to occur because external force deformation makes the situation that Electrical Bicycle integral body is scrapped; Described girder hypomere 3 middle part inner surfaces are provided with battery supporting plate 10.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
