Description

Frame cover of bicycle {Frame cover of bicyle}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a frame cover for a bicycle, and more particularly, to a frame cover provided outside of a metal base frame to enhance the appearance of an electric bicycle.

Generally, an electric bicycle includes a motor that rotates a wheel and a battery that supplies power to the motor. That is, a generator is mounted or an electric bicycle of the Series Hybrid type is driven by a motor electrically connected to the battery by rotating the wheel, and charging of the battery is performed by rotating the generator connected to the pedal by a pedal.

The bicycle is basically a chain that steps on the pedal with two feet, and transmits the power of the person who steps on the pedal to the wheel. The chain has a problem in that the structure is complicated, the occupied area of the bicycle is large, and the bicycle is detached from the wheel or the passenger's skirt is caught and contaminated.

In recent years, a chainless electric bicycle has been developed and used in consideration of this problem. Electric bicycles without a chain operate by pushing the button located on the handle or by stepping on the pedal.

In addition, the electric bicycle without the chain controls the pedal load so that the user can feel the pedal feeling as if the chain is present when the user depresses the pedal, so that the user can feel the pedal feeling when the pedal is rotated.

Korean Patent Publication No. 10-2014-0038024 (March 28, 2014). This document discloses an electric bicycle comprising a front frame provided with a front wheel and a handle applied by the present applicant, a rear frame provided with a rear wheel, and a center frame positioned between the front frame and the rear frame so as to be provided with a pedal and a saddle have. Further, the electric bicycle has an electronic control unit and a motor for driving, and basically has a considerable weight, so that the basic frame is made of an aluminum material excellent in rigidity, durability and gloss in order to reduce the weight. However, even though electric bicycles are made of aluminum, it is necessary to minimize them because they are heavier than general chain bicycles, and it is difficult to diversify designs and colors due to the characteristics of metal materials.

The frame cover of the bicycle according to the embodiment of the present invention can easily assemble the frame cover which can give various colors to the bicycle.

According to an aspect of the present invention, there is provided a metal base frame comprising a front base frame provided with a handle and a front wheel of a bicycle, a rear base frame provided with a rear wheel, and a middle base frame provided with a saddle and a pedal, A frame cover of the bicycle may be provided so as to cover the outer appearance of the base frame in various colors at the time of coupling.

Further, the frame cover may be provided on the middle base frame.

In addition, the frame cover may include a first frame cover and a second frame cover, and the first frame cover and the second frame cover may include a first binding unit and a second binding unit for mutually coupling each other .

Further, the first binding unit and the second binding unit are arranged alternately with the supporting member and the engaging member at regular intervals in the longitudinal direction, and between the front surface of the supporting member of the first binding unit and the back surface of the engaging member, 2 binding unit of the second binding unit is engaged and a supporting member of the second binding unit can be coupled between the back surface of the supporting member of the first binding unit and the front surface of the engaging member.

The support member may be provided with a stopper protruding from an end thereof, and the stopper may be provided at an end of the support member so as to be elastically supported by the stopper.

The first binding unit and the second binding unit may further include a step member on the back surface of the supporting member and the engaging member, respectively.

The frame cover of the bicycle according to the embodiment of the present invention is provided with a pair of left and right frame covers for covering the base frame of the metal material, and by using a binding unit provided inside the frame cover at the time of coupling, It is easy to assemble.

Further, since the frame cover of the bicycle according to the embodiment of the present invention is made of a synthetic resin material, various colors can be realized, and the appearance of the bicycle can be made beautiful.
