[0026] like Figure 6 As shown, the existing electric vehicle front fork includes a front fork direction rod 21, a front fork direction seat 22 and a front fork shock absorber rod 23. The bottom end of the front fork direction rod 21 is connected to the front fork direction seat 22, and the front fork direction rod 21 passes through the front fork direction seat 22. The two ends of the front fork direction seat 22 are respectively provided with the front fork shock absorber rod 23. The front fork direction rod 21 is connected to the handlebar component of the electric motorcycle or electric bicycle, the front fork direction seat 22 is matched with the front tube of the electric motorcycle or electric bicycle, and the front fork shock absorber rod 23 is matched with the front axle component of the electric motorcycle or electric bicycle.

[0027] When the front fork direction seat 22 is completely deformed and needs to be corrected during long-term use or collision, the front fork needs to be fixed first so that the front fork direction seat 22 can be corrected and straightened.

[0028] like Figures 1 to 5 The front fork correction device of an electric vehicle shown in the figure comprises a base 1, a fixing groove 2 is provided on the base 1, and a fixing plate 3 is detachably provided on the fixing groove 2;

[0029] The fixing groove 2 is an arc-shaped match with the front fork direction rod 21 of the front fork, and a groove 4 is provided on the side of the fixing plate 3 facing the fixing groove 2, and the cross section of the groove 4 is a triangle; when fixing the front fork of the electric vehicle, the front fork direction rod 21 of the front fork is first placed in the fixing groove 2 in a matching manner. Since the fixing groove 2 is an arc-shaped match with the outer surface of the front fork direction rod 21, it is convenient for the fixing groove 2 to accommodate the front fork direction rod 21. After the front fork direction rod 21 is placed in the fixing groove 2 in a matching manner, the side of the fixing plate 3 with the groove is matched and covered on the front fork direction rod On the rod 21, since a groove 4 is provided on the side of the fixing plate 3 facing the fixing groove 2, the cross section of the groove 4 is triangular, and the triangular groove 4 is convenient for adapting to the outer diameter of various front fork direction rods 21, which greatly improves the fixing adaptability of the fixing plate 3 and the fixing groove 2 to various models of front forks, and is convenient for fixing various electric vehicle front forks; in the present application, the fixing plate 3 is detachably connected to the fixing groove 2 by the screw 105, that is, the fixing plate 3 fixes the front fork direction rod 21 of the front fork in the fixing groove 2 by the screw 105, and finally fixes the front fork;

[0030] A top support rod 5 is provided at the upper part of one side of the base 1 away from the fixing groove 2, a bottom support rod 6 is provided at the lower part, and rear support plates 7 are provided at both sides;

[0031] Front support plates 10 are also provided on both sides of the second bottom rod. After the front fork is fixed, the two front fork shock absorbing rods 23 of the front fork are correspondingly matched and located between the top support rod 5, the bottom support rod 6 and the two support plates 7. In this application, the end of the front fork direction seat 22 that needs to be adjusted is set as end a, and the end of the front fork direction seat 22 that does not need to be adjusted is set as rod b. When the end a of the front fork direction seat 22 needs to be pressed down to achieve straightening, a pressing tool is placed between the top support rod 5 and the front fork shock absorbing rod 23 on the same side as the end a. In this application, a jack can be used as a pressing tool, and the jack is placed Between the top support rod 5 and the front fork shock absorber rod on the same side as the a-end, the front fork shock absorber rod 23 on the same side as the a-end is pressed downward by a jack, and the a-end of the front fork shock absorber rod 23 is pressed downward by utilizing the principle of lever; when the jack presses downward the front fork shock absorber rod 23 on the same side as the a-end, a spirit level can be placed on the two front fork shock absorber rods 23 to facilitate real-time observation of whether the front fork shock absorber rods are adjusted to the right position and in a horizontal state; if the two front fork shock absorber rods are in a horizontal state, the front fork direction seat 22 is straightened and corrected. Similarly, when end a needs to be lifted upward for straightening, the jack is placed on the bottom support bearing seat 6, and the front fork shock absorber rod 23 on the same side as end a is lifted upward by the jack, so that the front fork shock absorber rod 23 on the same side as end a is lifted upward, and the lever principle is used to further lift end a of the front fork direction seat; when the jack is lifting the front fork shock absorber rod 23 on the same side as end a, a spirit level can be placed on the two front fork shock absorber rods 23, and if the two front fork shock absorber rods are in a horizontal state, the front fork direction seat 22 is adjusted to be in a horizontal state, thereby achieving the straightening and correction of the front fork direction seat. When it is necessary to adjust the left and right deformation distance between the a-end and the b-end of the front fork direction seat, if it is necessary to adjust the a-end outward, first, place the support rod 30 between the front fork shock absorber rod 23 and the rear side 7 on the same side of the b-end, and then place the jack between the two front fork shock absorber rods, and use the jack to expand the front fork shock absorber rod 23 on the same side of the a-end outward until it is adjusted. When it is necessary to adjust the outward deformation of the b-end of the front fork direction seat, it is necessary to adjust the b-end inward. First, place the jack between the front fork shock absorber rod 23 and the rear support plate 7 on the same side of the b-end. When the jack placed next to the front fork shock absorber rod 23 on the same side of the b-end begins to exert force, Since the power of the jack is relatively large, it will drive the connection point between the steering rod and the steering seat to move toward point a or toward the position of another front support plate, causing secondary deformation. Therefore, a support rod 30 must be placed between the a end and the front support plate 10. The support rod 30 is a telescopic rod, which can play a role of fixed support. The support rod 30 can adapt to various distances between the front fork shock absorber rod 23 on the same side as the a and b ends and the front support plates 10 and 7. The support of the front fork shock absorber rod 23 on the same side as the a and b ends is achieved through the support rod, so that the distance between the front fork shock absorber rod on the same side as the a and b ends and the rear support plate 7 and the front support plate 10 remains constant.To achieve the distance adjustment between the a-end and the b-end of the front fork direction seat, when adjusting the distance between the a-end and the b-end, a center ruler can be placed on the two front fork shock absorber rods to facilitate real-time observation of whether the a-end is adjusted in place, thereby improving the adjustment efficiency of the a-end.

[0032] like Figure 7 As shown, the support rod 30 in the present application includes an outer rod 31 and an inner rod 32, one end of the inner rod 32 extends into the outer rod 31, and the end of the inner rod 32 extending into the outer rod 31 is threadedly connected to the outer rod 31, and the other end of the inner rod 32 is provided with an arc plate 33 matching the outer wall of the front fork shock absorber rod 23, and the other end of the outer rod 31 is provided with a support bearing seat (which can rotate 360 ​​degrees) 34; when in use, the support bearing seat 34 is abutted against the front support plate 10 or the rear support plate 7, and then the inner rod 31 is rotated to adjust the length of the outer rod 31 extending out of the inner rod 32 until the arc plate 33 on the inner rod 32 is matched and stuck on the outer wall of the front fork shock absorber rod 23, at this time, the support rod supports the front fork shock absorber rod, which is convenient for adjusting the two ends of the front fork direction seat.

[0033] As a preferred embodiment, the base 1 in the present application includes a first bottom bar 101 and a second bottom bar 102, a connecting plate 103 is provided between the first bottom bar 101 and the second bottom bar 102, and a plurality of plate connecting screw hole groups 104 are provided on the connecting plate 103, and the plate connecting screw hole groups 104 are located on both sides of the fixing slot 2;

[0035] Before the front fork direction seat 22 needs to be corrected, first place the front fork direction rod 21 of the front fork in the fixing groove 2 in a corresponding matching manner, and then cover the side of the first plate body 301 provided with the groove 2 on the front fork direction rod 21. Since the cross section of the groove 4 is a triangle, more preferably, the cross section of the groove 4 is an isosceles triangle, the triangular groove 4 structure is convenient for adapting to front fork direction rods 21 with various outer diameters, so that the correction device can adapt to front forks of various sizes. After the first plate body 301 is covered on the front fork direction rod 21, the screw 105 is passed through the screw connection hole 303 and the plate connection screw hole combination 104, and the connection between the first plate body 301 and the connecting plate 103 is realized by the screw 105, so that the front fork direction rod 21 of the front fork is fixed on the base 1, so as to facilitate the subsequent straightening and correction of the front fork direction seat 22.

[0036] As a preferred embodiment, a rod connecting screw hole group 106 is provided on the second bottom rod 102; the fixing plate 3 also includes a second plate body 302, and screw connecting holes 303 are respectively provided on both ends of the second plate body 302, and the screw connecting holes 303 of the second plate body 302 are connected to the rod connecting screw hole group 106 by screws 105.

[0037] In order to improve the fixing stability of the front fork, the present application also uses a second plate body 302 to fix the front fork direction seat 22. Specifically, after the first plate body 301 is covered on the front fork direction rod 21, the second plate body 302 is matched to cover the first plate body 301 and the front fork direction seat 22. When the front fork direction rod 21 of the front fork is placed in the fixing groove 2, the front fork direction seat 22 of the front fork is matched to be located on the connecting plate 103. In order to fix the front fork direction seat 22, the second plate body 302 in the present application is provided with a step 3021 at one end for fixing the front fork direction seat 22, so as to adapt to the height of the front fork direction seat 22 being higher than the connecting plate 103. The screw connection hole 303 corresponds to the screw connection hole 303 on the first plate body 301 and the plate connection screw hole group 104 on the connecting plate, and the screw connection hole 303 on one end of the second plate body 302 with the step 3021 corresponds to the rod connection screw hole group 106, and finally the first plate body 301, the second plate body 302 and the connecting plate 103 are connected by screws 105, and the second plate body 302 and the second bottom rod 102 are connected by screws 105, so that the front fork direction seat 22 is fixed between the second plate body 302 and the second bottom rod 102, which greatly improves the fixing stability of the correction device to the front fork, and facilitates the subsequent correction stability of the two ends of the front fork direction seat 22.

[0038] The second plate 302 is provided with a positioning center hole 3022. Before the front fork is fixed, center marking lines can be made at the center of the front fork direction rod 21 and the front fork direction seat 22, respectively. The setting of the positioning center hole 3022 on the second plate 302 is conducive to quickly identifying whether the center marking line of the front fork coincides with the center line of the positioning center hole 3022, so as to quickly realize the horizontal placement and fixation of the front fork.

[0039] As a preferred embodiment, the base 1 is provided with a connecting sleeve 8, and a screw 9 is matched inside the connecting sleeve 8. Since the front fork direction rod 21 passes through the front fork direction seat, the screw 9 can be matched and inserted into the front fork direction rod 21 extending out of the front fork direction seat 22. When the front fork is fixed to the base 1 through the fixing plate, the screw 9 is inserted into the front fork direction rod 21 by rotating the screw 9, so as to achieve the function of center positioning and fixing the front fork direction seat 22, thereby further improving the stability of the front fork fixation and ensuring the stability of the subsequent correction of the front fork direction seat 22.
