Technical Field

[0001] The invention relates to a purely mechanical automatically retractable tripod, belonging to the technical field of electric vehicle or motorcycle accessories. Background Art

[0002] Electric vehicles and motorcycles are easy to use, energy-saving, and inexpensive. They have become ubiquitous means of transportation, and their number far exceeds that of other types of vehicles.

[0003] The kickstands on electric bikes and motorcycles are used when parking to support the vehicle and prevent it from tipping over. However, existing kickstands are manually repositioned, and sometimes people forget to retract them when riding, creating potential dangers and poor safety. Summary of the Invention

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Embodiment of the present invention: The structural diagram of the purely mechanical automatic retracting tripod is as follows Figures 1 to 9As shown, it includes a connecting plate 2 connected to the frame 4, a first waist-shaped hole 5 is opened on the connecting plate 2, a rotating shaft 3 is inserted into the first waist-shaped hole 5, and the rotating shaft 3 is fixedly connected to the upper end of the foot support plate 1, a card slot 6 is opened at the lower part of the connecting plate 2, a hook 7 that cooperates with the card slot 6 is hingedly connected to the upper front part of the foot support plate 1 through a first hinge shaft 10, a posture control plate 19 and a swing block 15 are respectively provided on the upper back part of the foot support plate 1, a second waist-shaped hole 18 is opened at one end of the posture control plate 19, a second hinge shaft 17 that penetrates the second waist-shaped hole 18 is fixedly connected to the foot support plate 1, and a second hinge shaft 17 that penetrates the second waist-shaped hole 18 is fixedly connected to the foot support plate 1. A stop pin A13 is fixedly connected, and an arc groove A22 and an arc groove B21 are respectively provided on the side of the posture control plate 19. The swing block 15 is hinged to the foot support plate 1 through a third hinge shaft 16, and the head of the swing block 15 is pressed in the arc groove A22 and slides with the arc groove A22. A limit pin A14 corresponding to the arc groove B21 is fixedly connected on the connecting plate 2 and near the slot 6. A stop pin B12 is fixedly connected on the connecting plate 2 and near the upper end of the foot support plate 1. A torsion spring 11 is installed on the rotating shaft 3, and the torsion arms at both ends of the torsion spring 11 are elastically connected to the stop pin A13 and the stop pin B12 respectively.

[0020] See also Figure 5 and Figure 6 A limit pin B8 is fixedly attached to the connecting plate 2 near the slot 6. A limit boss 20 corresponding to the limit pin B8 is provided on the side of the foot support plate 1. Therefore, when the foot support plate 1 is deployed and supporting the ground, the limit pin B8 prevents the foot support plate 1 from further rotating and losing its support function, ensuring support stability. Furthermore, the foot support plate 1 has a rotation angle of less than 100 degrees, making it easy to control and store.

[0021] The working principle of the present invention is:

[0022] See also Figure 3 and Figure 4 When the rider of an electric vehicle or motorcycle wants to park, he can manually rotate the foot support plate 1 to unfold it. At this time, the foot support plate 1 is unfolded but does not support the ground, that is, the hook 7 has not yet engaged with the slot 6, and the foot support plate 1 is not locked, but the torsion spring 11 has been subjected to the rotational torque and has initially stored energy; at this time, the rider finds that this position is not the best parking position, the rider can retract the foot support plate 1 again and move it forward a distance to the best parking position.

[0023] See also Figure 5 and Figure 6When the rider reaches the optimal parking position, the foot support plate 1 rests on the ground to complete the parking maneuver. During the support process, under the pressure of the vehicle body, the rotating shaft 3 on the foot support plate 1 moves upward along the first waist-shaped hole 5 of the connecting plate 2. The posture control plate 19 on the other side of the foot support plate 1 also moves upward, driving the stop pin A13 to squeeze the torsion spring 11, causing the torsion spring 11 to further accumulate energy. Simultaneously, after the posture control plate 19 moves upward, the arcuate slot B21 on the posture control plate 19 is released from the restriction of the limit pin A14.

[0024] See also Figure 7 and Figure 8 When the rider rides the bicycle, the foot support plate 1 is separated from the ground. Without the pressure of the vehicle body weight, the elastic force of the torsion spring 11 is released, and the foot support plate 1 is driven to rotate in the opposite direction and retract, so that the hook 7 is disengaged from the engagement of the slot 6, and the foot support plate 1 is unlocked. At the same time, since the arc groove B21 on the posture control plate 19 has been separated from the restriction of the limit pin A14, the posture control plate 19 can smoothly bypass the limit pin A14 during the retraction of the foot support plate 1, thereby achieving the effect of automatic retraction of the foot support plate 1.

[0025] The present invention can easily replace the kickstand of an existing electric vehicle or motorcycle. During installation, it is only necessary to remove the existing kickstand and connect the connecting plate 2 of the present invention to the frame 4 without modifying the frame 4.

[0026] In summary, the present invention is a purely mechanical structure, and the bracket can be automatically retracted when riding, ensuring riding safety. At the same time, 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, improving the convenience of parking.
