[0030] like Figures 1-5 As shown, this is a motorcycle front fork assembly provided in one embodiment of the present invention.

[0031] In one exemplary embodiment, the motorcycle front fork assembly includes:

[0032] A connecting plate assembly, comprising an upper connecting plate 2 and a lower connecting plate 1, with a head tube 3 provided between the upper connecting plate 2 and the lower connecting plate 1;

[0033] The head tube 3 is provided with a fixing block 5, and the upper connecting plate 2 and / or the lower connecting plate 1 are detachably connected to a limiting block 6. The limiting block 6 is used to rotate with the connecting plate assembly. The limiting block 6 is provided with a limiting groove 606. At least a part of the fixing block 5 is located in the limiting groove 606. The fixing block 5 can be used to limit the rotation angle of the limiting block 6.

[0034] In this embodiment, the limiting block 6 can be detachably connected to the lower connecting plate 1, enabling quick assembly and disassembly, adapting to different motorcycle types, and allowing the motorcycle to adapt to different rotation angles, thereby improving the assembly efficiency of the front fork assembly and enhancing the performance of the motorcycle.

[0035] In this embodiment, the limiting block 6 can be installed on the lower connecting plate 1, the upper connecting plate 2, or both. Therefore, the limiting block 6 can be installed according to the specific structure of the head tube 3 to adapt to different vehicle models and improve the assembly efficiency of the front fork assembly. In a specific embodiment, the limiting block 6 is installed on the lower connecting plate 1.

[0036] In an exemplary embodiment, the lower connecting plate 1 is provided with a mounting groove, and the mounting groove is provided with at least one first connecting hole 106. The limiting block 6 is detachably connected to the mounting groove, and the limiting block 6 is provided with a second connecting hole 605 corresponding to the first connecting hole 106.

[0037] In this embodiment, the mounting groove can be adapted to the external shape of the limiting block 6, and the limiting block 6 can be initially positioned to facilitate the installation of the limiting block 6. During installation, the bottom of the limiting block 6 only needs to be placed into the mounting groove, and then the two are connected by means of connectors (screws, bolts) through the first connecting hole 106 provided in the mounting groove and the corresponding second connecting hole 605 provided on the limiting block 6.

[0038] For example, in this embodiment, there are two first connecting holes 106, which are symmetrically arranged in the mounting groove and located at the left and right ends of the mounting groove. Correspondingly, the second connecting holes 605 are located at the left and right ends of the limiting block 6.

[0039] For example, in this embodiment, the limiting block 6 is made entirely of metal to improve its strength.

[0040] It is worth noting that in this embodiment, other connecting mechanisms can also be provided between the mounting groove and the limiting block 6, such as a concave-convex fit between the mounting groove and the limiting block 6, and a buckle or other structure at the concave-convex fit, so as to improve the connection strength between the lower connecting plate 1 and the limiting block 6.

[0041] In an exemplary embodiment, the limiting block 6 is provided with a first limiting protrusion 601 and a second limiting protrusion 602, and the first limiting protrusion 601 and the second limiting protrusion 602 form a limiting groove 606.

[0042] In this embodiment, the limiting groove 606 formed by the first and second protrusions can limit the fixing block 5 by the first limiting protrusion 601 and the second limiting protrusion 602.

[0043] For example, in this embodiment, the protrusion direction of the first limiting protrusion 601 and the second limiting protrusion 602 is: protruding obliquely from the front side of the motorcycle toward the head tube 3, and the width of the limiting groove 606 gradually decreases along the rearward direction of the front side of the motorcycle.

[0044] For example, when the motorcycle is not turning, the first protrusion and the second protrusion are symmetrically arranged on the left and right sides of the fixing block 5 to limit the motorcycle's left and right turns.

[0045] For example, in this embodiment, the relative rotation angle between the fixing block 5 and the limiting block 6 is -23° to 23°. When the motorcycle is not turning, it is located at the middle position between the first limiting protrusion 601 and the second limiting protrusion 602.

[0046] like Figure 2 As shown, it is worth noting that the fixing block 5 has a first contact sidewall 501 and a second contact sidewall 502, the first limiting protrusion 601 has a first limiting inclined surface 603, and the second limiting protrusion 602 has a second limiting inclined surface 604. When the limiting block 6 is at its maximum rotation angle, the first limiting inclined surface 603 is parallel to and abuts against the first contact sidewall 501, or the second limiting inclined surface 604 is parallel to and abuts against the second contact sidewall 502. By the cooperation of the first limiting inclined surface 603 and the first contact sidewall 501, and the cooperation of the second limiting inclined surface 604 and the second contact sidewall 502, the left and right turns of the motorcycle are limited, as shown. Figure 2The rotation angle shown is the maximum rotation angle of the connecting plate assembly. In this embodiment, when the motorcycle rotates to the limit distance and the limiting block 6 limits the fixing block 5, the limiting block 6 will contact the fixing block 5. Therefore, setting the contact surface of the two when they contact each other can increase the contact area between them. Limiting is achieved by the plane pressing together, which reduces the local stress of the limiting block 6, reduces the wear of the fixing block 5, and improves the service life of the limiting block 6.

[0047] In an exemplary embodiment, a directional post 4 is provided between the upper connecting plate 2 and the lower connecting plate 1. One end of the directional post 4 is connected to the lower connecting plate 1, and the other end of the directional post 4 passes through the lower connecting plate 1 and is detachably connected to the upper connecting plate 2.

[0048] In this embodiment, the connection between the upper connecting plate 2 and the lower connecting plate 1 can be achieved through the directional column 4 set between the upper connecting plate 2 and the lower connecting plate 1.

[0049] For example, the lower connecting plate 1 is provided with a stepped groove 105, and the steering column 4 is provided with a stepped mating part 401 that mates with the stepped groove 105. The end of the steering column 4 away from the stepped mating part 401 is threadedly connected to the upper connecting plate 2. During installation, the steering column 4 is pushed upward from the bottom of the lower connecting plate 1 until the stepped mating part 401 at the bottom of the steering column 4 is engaged with the stepped groove 105 to achieve positioning between the steering column 4 and the lower connecting plate 1. The connection between the upper connecting plate 2 and the steering column 4 is achieved by threaded locking to achieve quick connection.

[0050] In an exemplary embodiment, a first connector 7 and a second connector 8 are fixedly connected to the head tube 3, and the head tube 3 is also provided with a mounting bracket 9 for mounting the head assembly. The mounting bracket 9 is detachably connected to the first connector 7 and the second connector 8.

[0051] In this embodiment, the first connector 7 and the second connector 8 enable quick assembly and disassembly of the mounting bracket 9, thereby allowing the front assembly to be quickly installed on the mounting bracket 9 and improving the installation efficiency of the front assembly.

[0052] For example, in this embodiment, the first connector 7 and the second connector 8 are both hollow tubes. During installation, it is only necessary to align the mounting bracket 9 with the first connector 7 and the second connector 8, and use locking devices such as screws or bolts to fix them.

[0053] It is worth noting that in this embodiment, the first connector 7 and the second connector 8 are fixed to the head tube 3 by welding. When fixing the first connector 7 and the second connector 8, the first connector 7 is welded to the upper end of the fixing block 5, which can improve the strength of the fixing block 5.

[0054] In an exemplary embodiment, a weight-reducing groove 103 is provided on the side of the lower connecting plate 1 away from the upper connecting plate 2, and an avoidance groove 104 is provided in the weight-reducing groove 103.

[0055] In this embodiment, the weight reduction grooves 103 can reduce the overall weight of the lower connecting plate 1. There are two weight reduction grooves 103. The lower connecting plate 1 has mounting holes 101 for installing shock absorbers 10. There is a gap at the mounting hole 101. A locking connection hole 102 is provided on one side of the gap. The locking connection hole 102 is fixed by screws or other fasteners to reduce the diameter of the mounting hole 101 to hold the shock absorber 10 tightly. Since there are two locking connection holes 102 and two fasteners, the clearance groove 104 opened in the weight reduction grooves 103 can facilitate the installation of fasteners and further reduce the overall weight of the lower connecting plate 1, thereby improving the lightweight performance of the motorcycle.

[0056] For example, in this embodiment, the upper connecting plate 2 is also provided with a plurality of weight-reducing grooves 103 to reduce the weight of the upper connecting plate 2.

[0057] This utility model also provides a motorcycle, which includes the above-described motorcycle front fork assembly.

[0058] In summary, this utility model, through the setting of the limiting block 6, can be detachably connected to the lower connecting plate 1, enabling quick assembly and disassembly, adapting to different motorcycle types, and allowing the motorcycle to be adapted to different rotation angles, thereby improving the assembly efficiency of the front fork assembly and enhancing the performance of the motorcycle.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
