Bolts 19 are provided at the top of the frame 12, and mounting blocks 14 are provided in the two fixing frames 12. A slot at one end of the fixing member 13 is threadedly connected to a thread groove at one side of the front fork arm frame 11 through a slot at the bottom of the fixing frame 12. One end of the fixing member 13 passes through the top of the fixing frame 12 and is threadedly connected to a thread groove at the top of the mounting block 14. Plate buckles 15 are provided on the opposite sides of the two mounting blocks 14. Active rods 16 are provided inside the two mounting blocks 14. Springs 17 are provided on the outer surfaces of the two active rods 16. Blocks 15 are provided at the ends of the two active rods 16 away from the plate buckles 15. 8. A bearing seat 110 is arranged on the inner wall of the card slot opened at the center of the top of the front fork arm frame 11. A front fork riser 111 is arranged in the bearing seat 110. The side of the plate buckle 15 close to the mounting block 14 contacts the side of the mounting block 14 away from the front fork riser 111. One end of the movable rod 16 is movably connected inside the plate buckle 15. The other end of the movable rod 16 passes through the inner ring of the spring 17 and is fixedly connected to the end of the card block 18 away from the front fork riser 111. A front fork connecting pipe 112 is arranged outside the front fork riser 111. Four positioning holes 113 are arranged in a circular array on the outer surface of the front fork connection. One end of the spring 17 is fixed to the card block. 18 is fixedly connected to one end of the movable rod 16, the other end of the spring 17 is fixedly connected to the side of the inner wall of the mounting block 14 away from the clamping block 18, one end of the clamping block 18 is clamped in the positioning hole 113, the outer surface of the bearing seat 110 is fixedly connected to the inner wall of the clamping groove opened at the top center of the front fork arm frame 11, the inner surface of the bearing seat 110 is fixedly connected to the bottom end of the front fork stem 111, the front fork connecting tube 112 is nested outside the front fork stem 111, the threaded groove opened on the inner wall of the front fork connecting tube 112 is threadedly connected to the threaded part at the top of the front fork stem 111, and a protective mechanism 2 is provided at the bottom of the front fork arm frame 11.

[0024] In this embodiment, when the staff is installing the shock-absorbing front fork of the electric vehicle on the front fork connecting tube 112 of the front of the vehicle, first, the plate buckle 15 is toggled. When the plate buckle 15 is toggled, the movable rod 16 and the clamping block 18 will be synchronously driven to move in the force direction, and then the clamping block 18 will slide into the inside of the installation block 14, and the spring 17 will be deformed by the extrusion force from the movement of the clamping block 18. Then the staff needs to put the front fork connecting tube 112 on the front fork riser 111 to ensure that the positions of the two are aligned. Subsequently, the threaded groove on the inner wall of the front fork connecting tube 112 is threadedly fixed to the threaded portion at the top of the front fork riser 111. This step requires careful Careful operation is performed to ensure that the rotation direction of the thread is correct and the tightening force of the thread is moderate to avoid damage to the thread due to over-tightening or loose connection due to insufficient tightening. The front fork connecting tube 112 and the front fork stem 111 are fixed together by threads, and the firmness between the two is effectively guaranteed. At the same time, the staff loosens the plate buckle 15, and then the spring 17 loses the extrusion force to push the block 18 into the positioning hole 113, so that the front fork connecting tube 112 is better limited to the current position of the front fork stem 111, so as to avoid loosening of the connection between the front fork connecting tube 112 and the front fork stem 111 due to bumps in the road or vibrations of the vehicle during driving.

[0025] like Figure 1-Figure 4 As shown, the protection mechanism 2 includes a connecting frame 21, and protection plates 22 are connected to both sides of the top of the connecting frame 21. Fixing holes 23 are opened on the opposite sides of the two protection plates 22. A fixing rod 24 passes through the fixing hole 23. One end of the fixing rod 24 passes through the fixing hole 23 and is threadedly connected to the thread groove opened on the top of the connecting frame 21. The inner wall of the connecting frame 21 is fixedly connected to the outer surfaces of the two front fork sleeves 33 on both sides.

[0026] In this embodiment, the connecting frame 21 can ensure the stability of the two shock absorbing components. In addition, the protective plate 22 can protect the front fork side tube 31, the shock absorbing spring 32 and the front fork sleeve 33 to prevent them from being damaged by external factors. In addition, it can also prevent silt and dust from adhering to their surface to avoid inconvenience for the staff in cleaning. At the same time, when it is necessary to clean the dust and silt on the protective plate 22, the protective plate 22 and the connecting frame 21 can be released by rotating the fixing rod 24 counterclockwise to release the limit, and the protective plate 22 can be removed for cleaning.

[0027] The utility model provides a shock-absorbing front fork for an electric power-assisted vehicle that is easy to install. The specific working principle is as follows:

[0028] During the assembly process of the electric vehicle, the staff needs to install the front fork part of the electric vehicle. In this process, the plate buckle 15 needs to be moved first. When the plate buckle 15 is moved, it will synchronously drive the movable rod 16 and the block 18 to move in the force direction, so that the block 18 can slide smoothly into the installation block 14. In this process, the spring 17 will also be squeezed by the squeezing force from the block 18 when it moves, so as to perform telescopic deformation. Then the staff needs to put the front fork connecting tube 112 on the front fork riser 111 to ensure that the positions of the two are aligned. Subsequently, the threaded groove on the inner wall of the front fork connecting tube 112 is aligned with the front fork riser. The threaded portion at the top of 111 is threadedly fixed. At this time, the staff can loosen the plate buckle 15. After the spring 17 loses the extrusion force, it will push the block 18 to get into the positioning hole 113, so that the front fork connecting pipe 112 is better limited at the current position of the front fork seat tube 111. The protective plate 22 can protect the front fork side tube 31, the shock absorber spring 32 and the front fork sleeve 33 to prevent them from being damaged by external factors. When it is necessary to clean the dust and sludge on the protective plate 22, the protective plate 22 and the connecting frame 21 can be released by rotating the fixing rod 24 counterclockwise, and the protective plate 22 can be removed for cleaning.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
