Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.

Embodiments of the invention: the structure schematic diagram of the purely mechanical automatic retraction foot rest is shown in fig. 1-9, the purely mechanical automatic retraction foot rest comprises a connecting plate 2 connected with a frame 4, a first waist-shaped hole 5 is formed in the connecting plate 2, a rotating shaft 3 penetrates into the first waist-shaped hole 5, the rotating shaft 3 is fixedly connected to the upper end of a foot supporting plate 1, a clamping groove 6 is formed in the lower portion of the connecting plate 2, a hook 7 matched with the clamping groove 6 is hinged to the front upper portion of the foot supporting plate 1 through a first hinge shaft 10, a gesture control plate 19 and a swinging block 15 are respectively arranged on the upper back surface of the foot supporting plate 1, a second waist-shaped hole 18 is formed in one end of the gesture control plate 19, a second hinge shaft 17 penetrating into the second waist-shaped hole 18 is fixedly connected to the foot supporting plate 1, a stop pin A13 is fixedly connected to the other end of the gesture control plate 19, an arc-shaped groove A20 and an arc-shaped groove B21 are respectively arranged on the side surface of the gesture control plate 19, the swinging block 15 is hinged to the foot supporting plate 1 through a third shaft 16, the head of the swinging block 15 is propped against the arc-shaped groove A20 and is matched with the clamping groove 6, the swing pin is connected to the stop pin 2A 2 and the stop pin 13 at the position of the corresponding position of the stop pin B12 and the stop pin 1, and the stop pin is fixedly connected to the stop pin 11 on the two stop pin B12 and the stop pin 2 at the position of the stop plate 1.

Referring to fig. 5 and 6, a limit pin B8 is fixedly connected to the connecting plate 2 at a position close to the clamping groove 6, and a limit boss 20 corresponding to the limit pin B8 is disposed on the side portion of the foot supporting plate 1. Therefore, when the foot rest plate 1 is unfolded and supports the ground, the foot rest plate 1 is prevented from continuing to rotate through the limiting pin B8 to lose the supporting function, so that the supporting stability is ensured. Meanwhile, the rotating angle of the foot support plate 1 is smaller than 100 degrees, so that the control and storage are convenient.

The working principle of the invention is as follows:

referring to fig. 3 and 4, when the rider wants to park the electric vehicle or motorcycle, the rider can manually rotate the foot support plate 1 to expand the electric vehicle or motorcycle, and the foot support plate 1 is expanded but not supported on the ground, namely the hooks 7 are not clamped with the clamping grooves 6, the foot support plate 1 is not locked, but the torsion spring 11 is subjected to the rotational torsion force to store energy preliminarily; at this time, the rider finds that the position is not the optimal parking position, and the rider can retract the footrest 1 again and then advance a distance to the optimal parking position.

Referring to fig. 5 and 6, when the rider drives to the optimal parking position, the foot support plate 1 is supported on the ground, and the parking operation is completed. In the supporting process of the foot support plate 1, under the pressure action of the vehicle body, the rotating shaft 3 on the foot support plate 1 moves upwards along the first waist-shaped hole 5 of the connecting plate 2, and the attitude control plate 19 on the other side of the foot support plate 1 also moves upwards together to drive the stop pin A13 to squeeze the torsion spring 11, so that the torsion spring 11 stores energy further; meanwhile, after the attitude control plate 19 is moved up, the arc-shaped groove B21 on the attitude control plate 19 is disengaged from the restriction of the stopper pin a 14.

Referring to fig. 7 and 8, when the rider rides the bicycle, the foot rest plate 1 is separated from the ground, under the pressure of no weight of the bicycle body, the elastic force of the torsion spring 11 is released, and drives the foot rest plate 1 to reversely rotate and retract, so that the hook 7 is separated from the clamping groove 6 to be clamped, and the foot rest plate 1 is unlocked, meanwhile, since the arc-shaped groove B21 on the gesture control plate 19 is separated from the limit of the limit pin a14, the gesture control plate 19 can smoothly bypass the limit pin a14 in the retracting process of the foot rest plate 1, and the automatic retracting effect of the foot rest plate 1 is achieved.

The invention can be convenient for replacing the existing heel brace of the electric vehicle or the motorcycle, and when the electric vehicle or the motorcycle is installed, the connecting plate 2 of the invention is connected with the frame 4 only by disassembling the existing heel brace, and the frame 4 is not required to be refitted.

In summary, the invention has a purely mechanical structure, and the bracket can be automatically retracted when riding, so that riding safety is ensured. Meanwhile, after the foot support plate 1 is unfolded, as long as the foot support plate 1 is not supported on the ground, the foot support plate 1 can still be retracted again, and convenience in parking is improved.
