[0002] Electric vehicles are environmentally friendly, lightweight, and labor-saving, and are widely favored by people. The center support of electric vehicles uses the lever principle to complete the parking process. The center support is an indispensable component of motorcycles and electric vehicles. When parking, the center support is used to lift the body of the vehicle; when parking is required, the rider stands beside the vehicle, steps on the center support with one foot, and supports the center support from the back of the center support, pulling the motorcycle or electric vehicle to the rear of the body, so that the body is rotated along the center support with the center support as the fulcrum, and the body is parked with the center support.

[0003] The existing electric vehicle center stand and the bottom of the electric vehicle are rotatably connected via bearings to achieve the retraction and extension of the electric vehicle center stand. However, after long-term use, the internal lubricant of the bearing will be lost, causing the bearing to easily wear when it is retracted and extended, thereby reducing the smoothness of the electric vehicle center stand when it is retracted and extended, which is likely to have an adverse effect on the normal use of the electric vehicle center stand.

[0024] The following is a clear and complete description of the technical solution of the utility model patent. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See attached Figure 1-5 A wear-resistant center support for a two-wheeled electric vehicle comprises a support frame 1 for supporting a battery vehicle, a mounting plate, a connecting ear plate 2 and a driving bearing 4, two connecting ear plates 2 are symmetrically mounted on the top of the support frame 1, the mounting plate is arranged between the two connecting ear plates 2, wherein the top of the mounting plate is connected to the bottom of the electric vehicle, so that the support frame 1 supports the bottom of the electric vehicle.

[0027] The adjacent sides of the two connecting ear plates 2 are each provided with a mounting hole, and a driving bearing 4 is fixedly installed in the inner cavity of the mounting hole, and rotating shafts are fixedly installed on both sides of the mounting plate. The ends of the two rotating shafts away from the mounting plate pass through the mounting holes and are fixedly connected to the inner walls of the driving bearing 4. A lubrication component is provided on the outside of the connecting ear plates 2 to prevent the driving bearing 4 from being worn. When the support frame 1 is retracted or extended, the rotating shaft and the inner ring of the driving bearing 4 rotate together, which effectively reduces the resistance encountered by the support frame 1 when it is retracted or extended, prevents the support frame 1 from shaking when it is retracted or extended, and improves the stability of the support frame 1 when it is retracted or extended.

[0028] The lubrication assembly includes an oil supply cylinder 12, on the sides of the two connecting ear plates 2 away from each other are fixedly installed with mounting cylinders 3, the inner cavity of the mounting cylinder 3 is provided with an oil supply cylinder 12, one end of the oil supply cylinder 12 is fixedly connected to the outer wall of the connecting ear plate 2, and the end of the oil supply cylinder 12 connected to the outer wall of the connecting ear plate 2 is fixedly installed with an oil supply pipe 11 connected with its own inner cavity, and a through hole connected to the inner cavity of the mounting hole is provided on the side of the connecting ear plate 2 away from the mounting hole, and the end of the oil supply pipe 11 away from the oil supply cylinder 12 passes through the through hole and extends to the interior of the driving bearing 4, wherein the oil supply cylinder 12 is pressed to cause it to deform, so that the air pressure inside the oil supply cylinder 12 increases and the lubricating oil inside the oil supply cylinder 12 is continuously squeezed, and the lubricating oil flows to the interior of the driving bearing 4 through the oil supply pipe 11 under extrusion, thereby replenishing the lubricating oil to the ball inside the driving bearing 4, preventing the ball inside the driving bearing 4 from being worn, improving the smoothness of the support frame 1 when it is retracted and released, and reducing the adverse effects caused by the normal use of the support frame 1.

[0029] The lubrication assembly also includes a push plate 9. An end of the mounting cylinder 3 away from the connecting ear plate 2 is provided with a through hole connected to its own inner cavity. The push plate 9 is slidably installed in the inner cavity of the through hole. The push plate 9 is pushed to approach the oil supply cylinder 12 until the oil supply cylinder 12 is deformed, thereby improving the convenience of deformation of the oil supply cylinder 12.

[0030] The oil supply cylinder 12 is made of rubber material. The tops of the oil supply cylinder 12 and the mounting cylinder 3 are both provided with through holes connected to their own inner cavities. The top of the mounting cylinder 3 is provided with an oil replenishing pipe 14. One end of the oil replenishing pipe 14 passes through two through holes and extends into the inner cavity of the oil supply cylinder 12. When the lubricating oil inside the oil supply cylinder 12 is consumed, lubricating oil is added to the inside of the oil supply cylinder 12 through the oil replenishing pipe 14, which is beneficial to replenish the lubricating oil inside the oil supply cylinder 12.

[0031] A rubber plug 15 is movably mounted on one end of the oil replenishing pipe 14 away from the oil supply cylinder 12 to prevent the lubricating oil inside from leaking through the top of the oil replenishing pipe 14 when the oil supply cylinder 12 is squeezed and deformed.

[0032] The push plate 9 extends to one end of the inner cavity of the mounting cylinder 3 and is fixedly mounted with a pressure plate 13 for pressing the oil supply cylinder 12. The diameter of the pressure plate 13 is not less than the diameter of the oil supply cylinder 12. The diameter of the pressure plate 13 is the same as the diameter of the oil supply cylinder 12, which is beneficial to increase the contact area between one end of the push plate 9 and one end of the oil supply cylinder 12, allowing the oil supply cylinder 12 to deform evenly and increase the oil output of the lubricating oil.

[0033] A mounting tube 7 is provided directly above the push plate 9, the outer wall of the mounting tube 7 is fixedly connected to the outer wall of the mounting cylinder 3, and a plug-in column 5 is elastically installed in the inner cavity of the mounting tube 7, and the bottom of the plug-in column 5 extends to the outside of the mounting tube 7. A plurality of limiting teeth 10 are fixedly installed on the top of the push plate 9 along its own outer wall, and a clamping plate 8 that engages with the limiting teeth 10 is fixedly installed on the bottom of the plug-in column 5. When the push plate 9 completes sliding, the plug-in column 5 is pressed down to allow the clamping plate 8 to slide between two adjacent limiting teeth 10, thereby limiting the push plate 9 and preventing the push plate 9 from resetting, which is conducive to the push plate 9 continuing to squeeze the oil supply cylinder 12.

[0034] The outer wall of the plug-in column 5 is fixedly sleeved with a pressure spring 6, one end of which is fixedly connected to the inner wall of the mounting tube 7, wherein the pressure spring 6 can continuously exert a movement on the plug-in column 5 in a direction close to the push plate 9, which is conducive to resetting the plug-in column 5 after the movement.

[0035] The bottom of the clamping plate 8 is inclined away from the side of the mounting tube 3. Under the action of the top pressure spring 6, the clamping plate 8 is always engaged with the push plate 9. When the push plate 9 moves toward the inside of the mounting tube 3, the outer wall of the limiting tooth 10 is always in contact with the inclined end of the clamping plate 8 and exerts a continuous movement on the clamping plate 8 away from the push plate 9, which is beneficial for the push plate 9 to press on the oil supply tube 12 and effectively prevents the push plate 9 from resetting.

[0036] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
