Abstract

The utility model relates to a folding pedal which comprises a crank, a pedal, a slider block and a slider block base, wherein the slider block is composed of a back slider block in a shape like Chinese character 'tu' and a front slider block in a shape like Chinese character 'ao', and a convex head of the back slider block is plugged in a notch of the front slider block and is connected with a countersunk head rotating shaft; a torsion spring is installed on the countersunk head rotating shaft, and both ends of the torsion spring are respectively pressed at the lower parts of the front slider block and the back slider block; the back slider block is provided with a sliding locating mechanism, and a pedal screw is arranged at the front part of the front slider block; the slider block base is fixed at the outer end of the crank, and the slider block is arranged in a slide way of the slider block base; the pedal is arranged on the pedal screw of the front slider block through a pedal spindle. When the pedal is not used in normal times, the pedal is pulled out of the slide way and then folded towards the crank, and the pedal can be folded and contacted at the outer side of the crank under the function of the torsion spring. When the pedal is used, the pedal is rotated from the paralleled position with the crank to the vertical position, then the front slider block is pushed back to the slide way, and the pedal can be used normally. The folding pedal is reasonable in structure, convenient to fold and use, etc., and is suitable to be installed on electric bicycles.

Description

Electrical Bicycle is collapsible foot-operated

Technical field

It is foot-operated that the utility model relates to a kind of Electrical Bicycle, and particularly a kind of collapsible riding that can abut on the crank belongs to the bicycle field.

Background technology

The foot-operated of existing Electrical Bicycle all is to be fixedly mounted on the crank, use in case go up a slope or during the storage battery short of electricity, but because many Electrical Bicycles are provided with the pedal of broad, a lot of people like pin is placed on the pedal, leave to ride and rotate with crank, because it is foot-operated vertical with crank, need stretch out car body, take certain space,, foot-operated make car body wideer for the Electrical Bicycle of expanded letter shape, influence the alerting ability that vehicle is walked, owing to seldom use at ordinary times, there is the people simply will ride and lays down again, but can be foot-operated very awkward because of using when the battery short of electricity.

Summary of the invention

The purpose of this utility model is in order to overcome the foot-operated weak point that is fixedly mounted on the crank of Electrical Bicycle, and it is collapsible foot-operated to design a kind of Electrical Bicycle rational in infrastructure, easy to use, that can abut on the crank.

Collapsible the riding of Electrical Bicycle of the present utility model is on the basis that has crank now and ride, have additional slide block and take-up housing, described slide block is made up of convex shape rear slider and concave shape front-slider, the prominent head of rear slider is inserted in the notch of front-slider and through the countersunk head rotating shaft and connects, torsion spring is contained in the countersunk head rotating shaft, the torsion spring two ends are pressed against the bottom of front-slider and rear slider respectively, rear slider is provided with slide locating mechanism, the foot-operated screw that establish the front portion of front-slider, take-up housing is packed in the crank outer end, slide block is contained in the slideway of take-up housing, rides to be contained on the foot-operated screw of front-slider through pedal spindle.Above-mentioned slide locating mechanism comprises pellet shot from a slingshot hole, pellet shot from a slingshot pin, compression spring, set screw, back knock hole and prelocalization hole, described pellet shot from a slingshot hole is located on the rear slider, pellet shot from a slingshot pin and compression spring and set screw are contained in the pellet shot from a slingshot hole successively, back knock hole and prelocalization hole be located on the take-up housing inwall and the position of the pellet shot from a slingshot pin when pushing back and pulling out with slide block respectively corresponding.

Because the front-slider of slide block can be pulled out on the slideway of take-up housing, front-slider can be rotated and under the twisting force of torsion spring and abut in outside the crank along the countersunk head rotating shaft.In the time of need not riding at ordinary times, can be pulled outwardly, make front-slider pull out slideway, bend towards crank again, can make the foot-operated folding crank outside that abuts in because of the torsion spring effect with riding earlier.Need to use when foot-operated, only need to ride after the parallel position with the bent axle outside rotates into the upright position and again front-slider is back into the slideway, can normally use foot-operated.Solved foot-operated problem of being in the way at ordinary times, had advantages such as rational in infrastructure, folding and easy to use, be adapted at installing and using on the Electrical Bicycle.
