Description
Technical field
The utility model belongs to the Electrical Bicycle field, especially a kind of Electrical Bicycle chain guard.
Background technology
Electrical Bicycle be with storage battery as auxiliary energy, and possess foot-operated driving functions, flexibly, convenient, energy-saving and environmental protection, be that China's field of application is wider, and have the auxiliary vehicle of large development potentiality.The present Electrical Bicycle chain guard half chain cover structures that adopt, promptly the chain guard guar plate covers the leading portion of big chain plate and chain, has only the chain of rear flywheel position to be exposed at outside the chain guard more.Because chain guard is installed in the big chain plate and the chain outside, need take certain space, has increased the requirement to the length of car body pedal axle, the chain inboard does not have the easy slippage influence of inhibiting device to use, and the chain enclosure volume is big, and cost is higher, can not effectively protect battery case.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, provide a kind of reasonable in design, simple in structure, save space, simple appearance, avoid the chain slippage, have the Electrical Bicycle chain guard that can effectively protect chain, big chain plate and battery case function.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of Electrical Bicycle chain guard comprises a chain cover body, on the chain cover body, is shaped on mounting hole, and its right part at the chain cover body is shaped on chain through the hole, is shaped on the reinforcement groove in the bottom of chain cover body.
And, be shaped on postive stop baffle at the relative upper lateral part of reinforcement groove of chain cover body.
The advantage and the good effect of the utility model are:
1, this Electrical Bicycle chain right part of covering on the chain guard body is shaped on chain through the hole, is shaped on the reinforcement groove in the bottom of chain cover body, can shorten the pedal shaft length; Compact conformation; Save the space, cost-cutting is strengthened the setting of groove and is played the reinforced rib effect; Can effectively increase chain guard intensity, sturdy and durable.
2, this Electrical Bicycle chain relative upper lateral part of reinforcement groove of covering on the chain guard body is shaped on postive stop baffle, can effectively prevent the chain slippage.
3, the utility model reasonable in design, simple in structure, save the space, easy to assembly, the dismounting operation is simple; Can effectively prevent the chain slippage, compact conformation, advantages of small volume, saving in material, saving cost; And installing and locating is accurate; Sturdy and durable, simple appearance is smooth, has the function that can effectively protect chain, big chain plate and battery case.
