Technical Field

[0001] This invention relates to the technical field of fork guards, and more particularly to a fork guard mounting structure. Background Technology

[0002] Swing fork guards serve to shield and protect motor cables, brake cables, exposed mounting points, and mud and water on electric bicycles, making them a crucial component. Swing fork guards are typically fixed to the swing fork using bolts or clamps. During installation, it's essential to ensure an appropriate gap between the guard and the swing fork to protect it without hindering its movement. With the increasing number of electric bicycles on the market, swing fork guard designs have become increasingly diverse.

[0003] In the current technology, common swingarm guards are usually fastened with two bolts on one side. However, this method will cause great damage to the appearance and shape, and also requires high precision in the mounting holes and swingarm assembly. Moreover, the exposed bolts are prone to rust. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a flat fork guard mounting structure.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The insert piece is provided with a plurality of ribs, all of which extend along the first direction and are arranged sequentially along the width direction of the insert piece. The end faces of the ribs away from the insert piece abut against the fourth mating surface. The insert piece has a third mating surface opposite to the ribs, and the third mating surface abuts against the fifth mating surface.

[0010] In the aforementioned flat fork guard mounting structure, the slot has a sixth mating surface and a seventh mating surface. The sixth mating surface connects the upper end of the fourth mating surface and the upper end of the fifth mating surface, and the seventh mating surface connects the lower end of the fourth mating surface and the lower end of the fifth mating surface.

[0011] In the aforementioned flat fork guard installation structure, the box has a baffle rib inside, the baffle rib is located on one side of the sixth mating surface, one end of the baffle rib is connected to the inner wall of the box, and the other end of the baffle rib extends toward the seventh mating surface.

[0012] In the above-mentioned flat fork guard mounting structure, the upper end of the insert has a first mating surface and a second mating surface connected to the first mating surface, the other end of the baffle abuts against the first mating surface, and there is a gap between the second mating surface and the sixth mating surface.

[0013] In the aforementioned flat fork guard mounting structure, the lower end of the insert has a barbed hook, which abuts against the seventh mating surface.

[0014] In the aforementioned flat fork guard mounting structure, the insert has a protrusion with a smaller end and a larger end. The larger end of the protrusion is connected to at least three ribs. One side of the protrusion is the first mating surface, and the barb hook is located on the other side of the protrusion.

[0015] In the aforementioned flat fork guard mounting structure, a deformation groove is formed on the insert plate, the deformation groove is located on one side of the barb hook, and the deformation groove is formed between the two ribs.

Figure 11 This is a schematic diagram of the completed assembly of the left-side flat fork guard mounting structure of the present invention. See also: Figures 1 to 11 The diagram illustrates a preferred embodiment of a swingarm guard mounting structure, comprising: a swingarm assembly 1, a rear fender 2, and a swingarm guard 5. The rear fender 2 is connected to the swingarm assembly 1. A box 15 is provided on the rear fender 2, integrally connected to and protruding from the rear fender 2. A slot 16 is formed on one side of the box 15 facing a first direction. The slot 16 has a fifth mating surface 18 and a fourth mating surface 20 opposite to the fifth mating surface 18. The swingarm guard 5 has a... The end is connected to the flat fork assembly 1. The inner wall of the other end of the flat fork guard 5 is provided with an insert 7 that is detachably connected to the slot 16. The insert 7 is provided with several ribs 8. The several ribs 8 extend along the first direction and are arranged sequentially along the width direction of the insert 7. The end face of the several ribs 8 away from the insert 7 abuts against the fourth mating surface 20. The insert 7 has a third mating surface 14 opposite to the ribs 8. The third mating surface 14 abuts against the fifth mating surface 18. The assembly is reliable, the structure is simple, and there are few exposed bolts.

[0035] In a preferred embodiment, a fork guard mounting structure is installed on the left and right sides of the rear wheel assembly 4, with the left fork guard 5 and the right fork guard 5 arranged opposite to each other, and the mounting direction of the fork guard 5 is consistent with the first direction.

[0036] Furthermore, the first direction is as follows: Figure 1 The direction is shown from right to left.

[0037] Furthermore, the wall thickness of insert 7 is 5.2mm, the wall thickness of box 15 is 3.5mm, and the thickness of each rib 8 is 2mm. This is to facilitate disassembly and assembly and reduce the obstruction problem during the assembly of insert 7 and box 15.

[0038] In a preferred embodiment, the end face of the rib 8 furthest from the insert 7 is an arc surface, such as... Figure 4 As shown, the thickness of the rib 8 gradually increases from left to right, and the middle part of the rib 8 has an interference fit with the fourth mating surface 20, with an interference size of 0.1 mm.

[0039] In a preferred embodiment, the slot 16 has a sixth mating surface 17 and a seventh mating surface 21. The sixth mating surface 17 connects the upper end of the fourth mating surface 20 and the upper end of the fifth mating surface 18, and the seventh mating surface 21 connects the lower end of the fourth mating surface 20 and the lower end of the fifth mating surface 18.

[0040] In a preferred embodiment, such as Figure 6 As shown, a baffle 19 is provided inside the box 15. The baffle 19 is located on one side of the sixth mating surface 17. One end of the baffle 19 is connected to the inner wall of the box 15, and the other end of the baffle 19 extends toward the seventh mating surface 21.

[0041] In a preferred embodiment, the upper end of the insert 7 has a first mating surface 11, and the other end of the retaining rib 19 abuts against the first mating surface 11.

[0042] Furthermore, such as Figure 7 As shown, the height of the retaining rib 19 is 1mm. When the insert 7 is inserted into the slot 16 along the first direction, the other end of the retaining rib 19 abuts against the first mating surface 11 of the insert 7 to prevent the insert 7 from rotating clockwise around the tangent line between the retaining rib 19 and the first mating surface 11.

[0043] In a preferred embodiment, the upper end of the insert 7 has a second mating surface 12, such as... Figure 2 As shown, the second mating surface 12 is connected to the first mating surface 11.

[0044] Furthermore, there is a gap between the second mating surface 12 and the sixth mating surface 17, and the gap size is 0.2 mm.

[0045] In a preferred embodiment, the lower end of the insert 7 has a barbed hook 10, which abuts against the seventh mating surface 21.

[0046] Furthermore, such as Figure 7As shown, the height of the barb hook 10 is 1mm. When the insert 7 is inserted into the slot 16 along the first direction, the barb hook 10 and the seventh mating surface 21 are interference-fitted with an interference size of 0.1mm. This restricts the insert 7 from rotating counterclockwise around the tangent line where the barb hook 10 and the seventh mating surface 21 abut, and also prevents the insert 7 from coming out of the slot 16.

[0047] In a preferred embodiment, the insert 7 is inserted into the slot 16 of the box 15 of the rear fender 2, such as... Figure 8 As shown, a portion of the box 15 forms a first limit between the insert 7 and the fork guard 5. The other end of the baffle 19 abuts against the first mating surface 11 of the insert 7 to form a second limit. The barb hook 10 abuts against the seventh mating surface 21 to form a third limit. The third mating surface 14 of the insert 7 abuts against the fifth mating surface 18 of the slot 16, and the end face of the rib 8 away from the insert 7 is press-fitted with the fourth mating surface 20 of the slot 16 to form a fourth limit, preventing the insert 7 from slipping out in the first direction. The four limits cooperate to prevent the insert 7 from slipping out of the slot 16.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0049] In addition to the above, the present invention also has the following embodiments:

[0050] In further embodiments of the present invention, such as Figure 2 As shown, the insert 7 has a protrusion 22, which has a small end and a large end.

[0051] In a further embodiment of the present invention, a deformation groove 9 is provided on the insert 7. The deformation groove 9 is located on one side of the barb hook 10 and is located between the two ribs 8, which satisfies the strength requirements of the insert 7 and facilitates disassembly.

[0052] Furthermore, the length of the deformation groove 9 is 21.8 mm and the width is 3.2 mm, which makes the barb hook 10 easy to deform during disassembly.

[0053] In a further embodiment of the present invention, an elongated hole 13 is provided on the fork guard 5, and the elongated hole 13 is provided at one end of the fork guard 5 away from the insert 7.

[0054] In a further embodiment of the present invention, a stepped bolt 6 is installed in the elongated hole 13, and one end of the flat fork cover 5 is connected to the flat fork assembly 1 through the stepped bolt 6.

[0055] Furthermore, the specification of the stepped bolt 6 is M6 (M stands for metric thread).

[0056] In a further embodiment of the present invention, three flange bolts 3 are provided on the rear mudguard 2. One flange bolt 3 is located at the front end of the rear mudguard 2, and the other two flange bolts 3 are located on both sides of the box 15 respectively. The rear mudguard 2 is connected to the flat fork assembly 1 through the three flange bolts 3.

[0057] Furthermore, all three flange bolts 3 are M6 in size.

[0058] In a further embodiment of the present invention, the specific installation steps are as follows: Figure 9 As shown, the left side of the rear fender 2 is fixed to the left side of the horizontal fork assembly 1 using M6 flange bolts 3; as shown Figure 10 As shown, insert the insert 7 of the left flat fork guard 5 into the slot 16 of the box 15 of the rear fender 2 along the first direction, and then use M6 stepped bolts 6 to fix one end of the flat fork guard 5 to the flat fork assembly 1. This design structure and installation steps reduce the exposure of bolts without damaging the appearance, which can not only improve the assembly accuracy, but also save costs and enhance the overall product appeal of the vehicle.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.
