[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0023] according to Figure 1-7 As shown, this embodiment proposes an electric vehicle front fork with a shock-absorbing function, comprising a fixed sleeve 1, a crown fork 2, an inner shaft 3 and a sleeve 4. A fork bridge 5 is mounted on the sleeve 4 through an assembly component. A shock-absorbing component for reducing the shock of the inner shaft 3 is provided inside the sleeve 4. A sealing cover 6 is threadedly mounted on the lower end of the sleeve 4. A mounting seat 7 is provided at the bottom of the sealing cover 6. A lubrication component is provided at the upper end of the sleeve 4 for lubricating the inner shaft 3 and the inner wall of the sleeve 4. A buffer component is provided between the upper end of the inner shaft 3 and the crown fork 2.

[0024] The lubrication assembly includes an oil chamber 8, a partition 9, an oil outlet hole 10, a ball 11 and an automatic refueling assembly. The oil chamber 8 is located inside the upper end of the sleeve 4. A partition 9 is provided inside the oil chamber 8. The partition 9 divides the cross section of the oil chamber 8 into a U shape. The oil chamber 8 is provided with multiple groups of oil outlet holes 10 on the side close to the inner wall of the sleeve 4. The oil outlet end of the oil outlet hole 10 is rotatably installed with a ball 11. The outer wall of the ball 11 fits with the outer wall of the inner shaft 3. The upper end of the oil chamber 8 away from the inner wall of the sleeve 4 is provided with an automatic refueling assembly. The lubricating oil is stored through the oil chamber 8 and then discharged through the oil outlet hole 10. As the inner shaft 3 moves up and down, the ball 11 is driven to rotate, and then the outer wall of the inner shaft 3 is added with lubricating oil through the ball 11, thereby ensuring the lubrication between the inner shaft 3 and the inner wall of the upper end of the sleeve 4. At the same time, the setting of the ball 11 can also prevent the occurrence of excessive lubricating oil.

[0025] The automatic refueling assembly includes an oil storage bin 12, a pressure ring 13, an oil delivery pipe 14, a mounting groove 15, a sealing plug 16, a connecting rope 41 and a reset spring 42. The outer wall of the pressure ring 13 is slidably connected to the inner wall of the oil chamber 8, and the inner wall of the pressure ring 13 is slidably connected to the outer wall of the partition 9. The top of the sleeve 4 is provided with an oil storage bin 12, and the oil storage bin 12 is made of transparent material. An oil delivery pipe 14 is provided between the oil storage bin 12 and the oil chamber 8, and a mounting groove 15 is provided on the side and lower part of the oil delivery pipe 14. A sealing plug 16 is provided inside the mounting groove 15, and a connecting rope 41 is provided at the bottom of the sealing plug 16. The lower end of the connecting rope 41 is fixedly connected to the pressure ring 13, and a reset spring 42 is fixed between the sealing plug 16 and the mounting groove 15. As the inner shaft 3 moves up and down The movement drives the ball 11 to rotate, and then brings out the lubricating oil inside the oil chamber 8, causing the lubricating oil inside the oil chamber 8 to become less. At this time, the pressure ring 13 moves downward, and the downward pressure ring 13 pulls the sealing plug 16 downward synchronously through the connecting rope 41, thereby opening the oil pipe 14. At this time, the oil storage tank 12 is connected to the oil chamber 8, and lubricating oil is added to the oil chamber 8 to ensure that the oil chamber 8 can work normally. The oil storage tank 12 made of transparent material can easily observe the lack of internal oil volume, and thus can timely add lubricating oil to the oil storage tank 12. It is worth noting that when this structure leaves the factory, the lubricating oil inside the oil chamber 8 should be filled to two-thirds. At this time, the pressure ring 13 is located at the top of the oil chamber 8, and the return spring 42 pushes the sealing plug 16 to seal the oil pipe 14.

[0026] The shock absorber assembly includes a sealing ring 17, a first spring 18, a first limit block 19, a second spring 20, a second limit block 21 and an oil pressure assembly. A sealing ring 17 is provided at the upper end of the inner wall of the sleeve 4, and a first limit block 19 is provided below the sealing ring 17. The lower end of the inner shaft 3 is fixedly connected to the first limit block 19. A first spring 18 is provided between the sealing ring 17 and the first limit block 19. The first spring 18 is sleeved on the inner shaft 3. A second limit block 21 is provided below the first limit block 19. A second spring 20 is provided between the first limit block 19 and the second limit block 21. The first limit block 19 and the second limit block 21 are both slidably connected to the inner wall of the sleeve 4. An oil pressure assembly is provided below the second limit block 21. Through the arrangement of the first spring 18 and the second spring 20, the oil pressure assembly is coordinated to buffer and decompose the vibration force, reduce the vibration amplitude, and thus achieve the purpose of shock absorption.

[0027] The oil pressure assembly includes a first fixed plate 22, a second fixed plate 23, a through hole 24, a fixed sealing baffle 25, a rotating sealing baffle 26, a rotating shaft 27 and a clockwork disc 28. The first fixed plate 22 is provided below the second limit block 21. Hydraulic oil is filled between the second limit block 21 and the first fixed plate 22. A second fixed plate 23 is provided below the first fixed plate 22. The fixed sealing baffle 25 is fixedly connected to the center of the first fixed plate 22. The rotating sealing baffle 26 is rotatably connected to the center of the second fixed plate 23 through the rotating shaft 27. The fixed sealing baffle 25 and the rotating sealing baffle 26 cooperate with the first fixed plate 22 and the second fixed plate 23 to form a fan-shaped oil groove with an angle of 30°. The first fixed plate 22 is provided with a through hole 24 The through hole 24 is located just above the fan-shaped oil groove, and the lower end of the rotating shaft 27 is rotatably connected to the clockwork disk 28. When the fork body is vibrated, the inner shaft 3 will move downward. At this time, the inner shaft 3 pushes the first limit block 19 to compress the second spring 20 to contract. At the same time, the second spring 20 pushes the second limit block 21 to move downward and squeezes the hydraulic oil, so that the hydraulic oil enters the fan-shaped oil groove through the through hole 24, thereby driving the rotating sealing baffle 26 to rotate, and then driving the rotating shaft 27 to rotate. The lower end of the rotating shaft 27 tightens the spring in the clockwork disk 28, thereby buffering and decomposing the downward force exerted on the second spring 20. At the same time, when the second spring 20 and the clockwork are reset, the first spring 18 can reduce the reset amplitude of the second limit block 21, thereby achieving the purpose of reducing the vibration amplitude of the inner shaft 3.

[0028] The buffer assembly includes a mounting slot 29, a telescopic column 30, a pulley seat 31, a pulley 32 and a groove 33. The interior of the crown fork 2 is provided with a mounting slot 29, and a plurality of telescopic columns 30 are distributed in a circular array inside the mounting slot 29. The output end of the telescopic column 30 is provided with a pulley seat 31, and a pulley 32 is mounted on the pulley seat 31. The upper end of the inner shaft 3 is inserted into the crown fork 2, and a groove 33 is provided at a position where the inner shaft 3 is flush with the mounting slot 29. A first limiting ring 34 is fixed above the groove 33, and a second limiting ring 35 is fixed below the groove 33. When the front fork is subjected to gravity, the crown fork 2 presses down the inner shaft 3. At this time, the crown fork 2 and the inner shaft 3 move in position, forcing the pulley 32 inward, thereby causing the telescopic column 30 to contract, thereby providing preliminary buffering for the crown fork 2. The provision of the first limiting ring 34 and the second limiting ring 35 limits the connection between the crown fork 2 and the inner shaft 3, ensuring the stability of the connection.

[0029] The assembly component includes an assembly seat 36 and a fixing component. The assembly seat 36 is in the shape of an elongated strip and is fixed on the front inner wall of the sleeve 4. The two ends of the fork bridge 5 are slidingly connected to the assembly seat 36. The two ends of the fork bridge 5 are provided with a fixing component adapted to the assembly seat 36.

[0030] The fixing assembly includes a fixing seat 37, a clamping block 38, a slide 39 and a fixing bolt 40. The fixing seat 37 is L-shaped and is fixedly connected to the fork bridge 5. A slide 39 is provided on the fixing seat 37, and a clamping block 38 is slidably installed on the slide 39. The clamping block 38 cooperates with the fixing seat 37 and the fixing bolt 40 to lock the fork bridge 5 on the assembly seat 36. The clamping block 38 can be loosened by rotating the fixing bolt 40, so that the fork bridge 5 can move up and down on the assembly seat 36, thereby achieving the purpose of adjusting the height of the fork bridge 5.

[0031] When the front fork of the electric vehicle with shock absorption function is subjected to vibration, the inner shaft 3 moves downward to push the first limit block 19 downward, thereby pushing the second spring 20 to contract, and the spring pushes the second limit block 21 downward, thereby squeezing the hydraulic oil, and the hydraulic oil rushes into the fan-shaped oil chamber 8, thereby pushing the rotating sealing baffle 26 to rotate, and then driving the rotating shaft 27 to rotate, and then driving the spring in the spring disk 28 to wind up, and then the spring is reset, and the second spring 20 is reset. At this time, the first spring 18 buffers the thrust generated by the reset, thereby achieving the purpose of buffering the inner shaft 3. At the same time, as the inner shaft 3 moves up and down, the ball 11 is driven to rotate, and then the outer wall of the inner shaft 3 is lubricated by the ball 11, thereby ensuring lubrication between the inner shaft 3 and the inner wall of the upper end of the sleeve 4.
