Description
Technical Field
The utility model relates to an electric motorcycle car's frame field, concretely relates to electric motorcycle car's frame structure.
Background
The motorcycle is a commonly used transportation vehicle, and particularly is an indispensable transportation vehicle for people to go out in regions where public transport is relatively inaccessible.
In the prior art, in order to embody speed and bearing performance, a motorcycle generally adopts a fuel engine as power, and the motorcycle has a better using effect. With the development of scientific technology and the high requirements on environmental protection, fuel motorcycles gradually have more defects, such as high energy consumption, low efficiency, emission, difficult operation, gas pollution to the atmospheric environment, and the like. Therefore, the electric motorcycle replaces motorcycles to a great extent, the prior electric motorcycle structure can be generally divided into an electric motorcycle with a rear motor and an electric motorcycle with a middle motor, the two electric motorcycles undoubtedly arrange the motors as driving devices on the flat fork of the motorcycle, the existing electric motorcycle can only be suitable for one motor due to the limitation of the flat fork structure, different power devices cannot be switched randomly, and meanwhile, the motor is hung on the flat fork, so that the unsprung mass of the whole motorcycle is heavy, and the comfort of the whole motorcycle is reduced.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides an electric motorcycle car's frame construction, it is with motor module ization, increases the interchangeability of installation, reduces unsprung mass simultaneously and increases whole car travelling comfort.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a frame structure of electric motorcycle car which characterized in that: the electric bicycle comprises a bicycle frame, a motor assembly and a bottom fork, wherein the motor assembly is arranged on the bicycle frame, one end of the bottom fork is connected with the motor assembly, the motor assembly comprises a motor and motor suspension plates fixed at two ends of the motor, a motor suspension point on the bicycle frame is detachably connected with the motor suspension plates, the bottom fork is hinged to the motor suspension plates, and a hinge point of the bottom fork is located on an axis of a motor output shaft.
Furthermore, a motor suspension point on the frame is of a C-shaped structure, and at least three connection holes for connecting the motor suspension plate are distributed on the C-shaped structure.
Furthermore, support columns are further arranged between the motor suspension plates and located at two ends of the motor, and the support columns are distributed at four corners of the motor suspension plates.
Further, the motor suspension plate on one side of the motor output shaft comprises an outer suspension plate and an inner suspension plate, the outer suspension plate and the inner suspension plate are respectively positioned on the inner side and the outer side of the belt pulley connected to the motor output shaft, and the outer suspension plate and the inner suspension plate are also provided with the supporting columns.
The beneficial effects of the utility model include: the motor assembly integrates, can adapt to multiple motor as power under the condition that does not change the frame structure, has reduced unsprung mass and has improved whole car travelling comfort, and the chain stay rotation center axle is concentric forever with the motor center axle, does not change belt length forever when the rear wheel motion, improves belt life.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
The frame structure of the electric motorcycle as shown in fig. 1-3 comprises a frame 1, a motor assembly 2 and a bottom fork 3, wherein the motor assembly 2 is arranged on the frame 1, and one end of the bottom fork 3 is connected with the motor assembly 2. The motor assembly 2 comprises a motor 4 and motor suspension plates 5 fixed at two ends of the motor 4, the motor suspension plates 5 are connected with the motor 4, the motor suspension plates 5 are connected to the frame 1, and motor suspension points on the frame 1 are detachably connected with the motor suspension plates 5 through bolts, so that different motors can be matched with the same frame structure, and only the motor suspension plates 5 are matched with connection points on the frame 1. The motor 4 is mounted on the frame 1, so that the purposes of reducing unsprung mass and improving the comfort of the whole vehicle can be achieved.
The bottom fork 3 is hinged to the motor suspension plate 5, a hinged point of the bottom fork is located on an axis of an output shaft of the motor 4, when the bottom fork 3 rotates, the distance between a rear wheel and the output shaft of the motor 4 is not changed, a belt cannot be lengthened or shortened due to rotation of the bottom fork 3, and the service life of the belt can be prolonged.
As shown in fig. 2, in this embodiment, the motor suspension point on the frame 1 is a C-shaped structure, three connection holes for connecting the motor suspension plate 5 are distributed on the C-shaped structure, and another fixing hole of the motor suspension plate 5 is adjustably connected with the frame 1, so that the problem of improper installation due to over-positioning in the fixing process can be prevented.
As shown in fig. 3, in the motor assembly of this embodiment, support columns 6 are further disposed between the motor suspension plates 5 at two ends of the motor 4, and the support columns 6 are distributed at four corners of the motor suspension plates 4. The motor suspension plate 5 positioned on one side of the output shaft of the motor 4 comprises an outer suspension plate 7 and an inner suspension plate 8, the outer suspension plate 7 and the inner suspension plate 8 are respectively positioned in the inner side and the outer side of a belt pulley 9 connected to the output shaft of the motor 4, and the outer suspension plate 7 and the inner suspension plate 8 are also provided with the supporting columns 6.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
