Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] As Figures 1-3 shown, a two-wheeled vehicle parking anti-skid device is composed of an anti-skid structure and a hydraulic drive component. The anti-skid structure is composed of a support rod 3, an anti-slip wheel 5, a shock absorber spring 6 and an oil cylinder 10. One end of the support rod 3 is connected to the piston rod of the oil cylinder 10, and the anti-slip wheel 5 is rotatably placed at the other end of the support rod 3. An articulated shaft 2 is arranged near the middle position of the support rod 3, and a plurality of shock absorber springs 6 are arranged on the support rod 3. The shock absorber springs 6 are located between the articulated shaft 2 and the anti-slip wheel 5. The hydraulic drive component is composed of a lower anti-slip oil pump 7, an oil pipe 8 and an upper anti-slip oil pump 9. The lower anti-slip oil pump 7 is connected to the oil cylinder 10 through the oil pipe 8, and the upper anti-slip oil pump 9 is connected to the lower anti-slip oil pump 7 through the oil pipe 8.

[0024] During use, this device is applicable to two-wheeled electric vehicles or motorcycles with disc brakes. First, install two groups of anti-skid structures on the flat fork of the vehicle 13, and make the two anti-slip wheels 5 located on both sides of the rear wheel 4 of the vehicle 13 respectively. The support rod 3 is rotatably connected to the flat fork through the articulated shaft 2, and the shock absorber spring 6 on the support rod 3 is connected to the vehicle flat fork 1. Install the lower anti-slip oil pump 7 of the power supply component on the vehicle flat fork 1, and install the upper anti-slip oil pump 9 side by side beside the rear brake upper oil pump 17 of the rear brake of the vehicle 13, and connect it to the original rear brake control circuit of the vehicle 13. Through the handle 18 of the rear brake, the handle 18 of the rear brake can control the rear brake upper oil pump 17 and the upper anti-slip oil pump 9. There is a sequential working order when the handle 18 is controlled. When the handle 18 is pressed, the upper anti-slip oil pump 9 works first, raising the oil cylinder 10 to drive the support rod 3 to rotate, lowering the anti-slip wheel 5 to the bottom surface to play an anti-skid role. If deceleration is still required, continue to squeeze the handle 18 inward to push the rear brake upper oil pump 17 to work for deceleration. At this time, even if there is an emergency brake, since there are three wheels supporting the position of the rear wheel 4, it is not easy to roll over;

[0025] Example 2

[0026] As Figure 4 shown, the difference between this embodiment and Embodiment 1 is that: the oil-driven component is changed to a gas-driven component, which is composed of a cylinder, an air pump 15 and an air tank 14. The air pump 15 is connected to the cylinder through a trachea 16, and the air tank 14 is connected to the air pump 15 through a trachea 16. An electric control switch 11 and a power-off switch 12 are additionally provided. The electric control switch 11 is electrically connected to the air pump 15, and the power-off switch 12 is electrically connected to the air pump 15. When in use, the air pump 15 and the air tank 14 are both installed at the foot position of the vehicle 13, and the electric control switch 11 and the power-off switch 12 are installed on the handle of the vehicle 13. Through pneumatic drive, pressing the electric control switch 11 controls the oil pump to work, and the two anti-skid wheels 5 are lowered to the ground to play a role in preventing rollover. If deceleration is required, squeeze the handle 18 for normal braking operation. When braking, the two anti-skid wheels 5 have been lowered, so it is not easy to roll over when braking; the power-off switch 12 can cut off the power supply of the air pump 15 when the anti-skid wheels 5 are not needed.

[0027] Example 3

[0028] As Figures 5-6 described, the difference between this embodiment and Embodiment 2 is that: a parking switch 21 is also provided; when in use, the front brake 19 and the rear brake on the vehicle 13 are combined together and controlled by a single handle 18 to adapt to more vehicle models. The electric control switch 11 is incorporated into the brake light switch, and the parking switch 21 circuit is separately connected from the battery. When braking, the electric control switch 11 closes, and the air pump 15 is powered on and starts to work. Then the cylinder lowers the anti-skid wheels 5 for anti-skid; after the stop switch is pressed, the air pump 15 can be pneumatically actuated to make the cylinder lower the anti-skid wheels 5, and the parking switch 21 circuit can also work after the vehicle 13 is locked.

[0029] Example 4

[0030] As Figure 6 shown, the difference between this embodiment and Embodiment 1 is that: when in use, the oil pump 20 on the front brake, the oil pump 17 on the rear brake and the upper anti-skid oil pump 9 are combined together and controlled by a single handle 18. The upper anti-skid oil pump 9 is placed at the bottom, and the oil pumps 20 on the front brake and 17 on the rear brake can be adjusted according to need. The adjustable screw 23 at the upper anti-skid oil pump 9 can be finely adjusted to make the upper anti-skid oil pump 9 have two working gears, one is the working gear and the other is the non-working gear. If anti-rollover work is not required, the upper anti-skid oil pump 9 is adjusted to the non-working gear, and it cannot be controlled through the handle 18. This method can extend the service life, provide more riding selection modes and is more convenient to use.

[0031] Further, a locking key 24 is also provided, and a locking groove is provided on the handle 18; if you want to use it as a tricycle, rotate the locking key 24 to the first gear position, and the locking key 24 locks the handle 18 in the first gear position. At this time, the anti-slip wheels 5 are locked so that the two anti-slip wheels 5 always remain on the ground, that is, a tricycle is formed. If you need to stop, rotate the locking key 24 to the second gear position to lock both the anti-slip wheels 9 and the brakes, then you can brake and stop steadily in the tricycle mode.

[0032] The design in the present invention is simple to operate and is not much different from the original cycling control habits; it effectively prevents side slipping when parking, can strengthen the braking function, and the two anti-slip wheels 5, together with the brakes and the rear wheel 4, brake more sensitively, and the emergency stop is easy and stable; it can be used as a tricycle, with diverse functions, and is also convenient to push when the rear wheel 4 has no air.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
