Background

The electric vehicle with the Amy rear support is bought recently, and has the advantages that the rear support (legs) fixed on the shaft head of the rear wheel can enable the whole vehicle to be parked stably (no front-back shaking phenomenon exists relative to the middle support), and children can be placed safely; however, in use it was found that: to park the electric vehicle using the rear support, the user usually steps on the foot support with feet, then holds the handle at the back of the portable vehicle (at the position below the small backrest) with the right hand and exerts upward force, and then holds the left hand and exerts backward force to stop the vehicle support. Because most of the weight of the electric vehicle is at the rear part, the whole supporting process of the rear supporting leg is really very laborious; especially, the women who ride the electric motor car at present are many, this "the leg is laboursome" technical defect seems more outstanding, therefore, as a repairment person, I think this is a design defect, need overcome this defect in the technology, specially propose following technical scheme, also do little contribution to the innovation of the whole people.

when the bicycle needs to be taken out, the bicycle is operated according to a conventional bicycle taking method, namely, a lock plate of the existing rear supporting leg is moved backwards by feet to be in an unlocking state, the electric bicycle is pushed forwards to enable a rear wheel of the electric bicycle to land, the rear supporting leg at the moment automatically returns to the original position (close to the horizontal state) under the action of a tension spring, the improved pedal part additionally arranged flatly lies on a support of the existing rear supporting leg through the rotation of a hinge due to the fact that the vertical state of the pedal part and the supporting leg cannot be kept, the folding action of the pedal is completed, and the bicycle can be normally ridden.

The beneficial technological effect of this application is: because the structural part of the pedal is additionally arranged on one side of the existing rear supporting leg, the length of the protruding part of the vehicle leg is prolonged by the pedal, and the power for tilting the rear part of the vehicle by the gravity of a human body is increased; therefore, the technical defect that the existing rear supporting leg is labor-consuming in use is overcome, and the beneficial technical effect of the application is achieved.

Detailed Description

As shown in fig. 1 and 2, the improved rear supporting leg is composed of a hinge 1 and a pedal 2 which are connected with an existing rear supporting leg 3 of the vehicle; the hinge 1 adopts a flat plate type hinge (commonly called a hinge and a hinge) in the prior art, namely, the hinge is formed by hinging two folding plates and a hinge shaft; a folding plate of the hinge 1 is welded on a bracket 4 at one side of the existing rear supporting leg 3, the welded hinge 1 is positioned above a protruding part 5 of the vehicle leg, and a welded hinge shaft 11 is parallel to a shaft head 7 (horizontal axis) of the battery vehicle; the welded hinge 1 is connected with the existing rear supporting leg 3 into a whole;

a pedal plate 2 is welded on the other folding plate of the hinge 1, the pedal plate 2 is made of a steel plate with corrugations (the corrugations are not shown in the figure), and the trend of the corrugations is parallel to the axis (longitudinal axis) of a vehicle body 6 of the battery vehicle; thereby improving the structural stress strength of the pedal 2; the welded pedal 2 can be turned back and forth in the space between the protruding part 5 of the existing rear supporting leg 3 and the bracket 4 of the supporting leg; the rotation angle of the footboard 2 is less than 90 degrees due to the fact that the top end of the protruding portion 5 of the existing rear support leg 3 is tilted upward (as shown in fig. 1); the welded pedal 2 is connected with the existing rear supporting leg 3 into a whole through a hinge 1;

the using method of the invention is as follows: when the existing rear supporting leg 3 is needed to be used for parking the bicycle, the pedal 2 lying on the existing rear supporting leg 3 is lifted upwards by the tiptoes to be rotated to be in contact with the protruding part 5 (some cat ears) of the bicycle leg, and then the pedal 2 is stepped downwards to enable the lower part of the protruding part 5 of the existing rear supporting leg 3 to be in contact with the ground 8; the existing rear support leg 3 is now in an inclined state (as shown in fig. 1); then use the tiptoe to make the heel of people step on the top of running-board 2 as the rotatory heel of centre of a circle, move the focus of human body to this foot, this car is at the fulcrum of current rear support leg 3 (the place that contacts ground is the fulcrum of car leg) and under the lever action of running-board 2 this moment, the rear portion of vehicle just is the perk upwards by human heavy pressure, thereby makes current rear support leg 3 change from the tilt state to standing state, the locking plate 9 of vehicle also pins the rear support leg under the effect of extension spring 10, accomplish the use of once supporting of rear support leg;
