Description

Technical Field

[0001] This utility model relates to the field of bicycle rim technology, and in particular to an impact-resistant and high-toughness bicycle rim. Background Technology

[0002] The bicycle rim is the core ring-shaped structural component of the wheel system, directly supporting the tire and together with the spokes and hubs, forming the wheelset system.

[0003] Existing bicycle rims are generally made of stainless steel or aluminum alloy, with some high-end rims made of carbon fiber. However, due to the lack of reinforcing mechanisms, the rims are susceptible to deformation and damage when rolling on uneven surfaces, exhibiting poor impact resistance. Furthermore, because the rims rely solely on spokes for added toughness, impact forces are concentrated at the stress points, leading to cracking and insufficient resilience, resulting in poor performance. Therefore, we propose a high-toughness, impact-resistant bicycle rim. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an impact-resistant, high-toughness bicycle rim.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: designing an impact-resistant and high-toughness bicycle rim, including an outer rim, with a bushing coaxially arranged inside the outer rim, and the outer surface of the bushing being connected to the inner surface of the outer rim by a number of spokes;

[0006] The outer side of the outer ring is recessed inward to form a groove, and a first arc plate and a second arc plate are provided inside the groove. The second arc plate is symmetrically arranged with the first arc plate, and a second connecting piece is installed at both ends of the first arc plate. A first connecting piece is installed at both ends of the second arc plate. When the inner surfaces of the first arc plate and the second arc plate are in contact with the inner wall of the groove, the first connecting piece and the corresponding second connecting piece are staggered, and adjacent first connecting pieces and second connecting pieces are connected by a fastening mechanism.

[0007] A curved support plate is symmetrically provided on both sides of the first and second curved plates. One side of the curved support plate is in contact with the inner wall of the groove, and a curved skirt extends from one side of each curved support plate.

[0008] Several wedge blocks are installed on one side of each arc-shaped skirt. Several wedge grooves are symmetrically opened on both sides of the inner surface of the first arc-shaped plate and the second arc-shaped plate. One side of each wedge block extends into the corresponding wedge groove.

[0009] Preferably, the fastening mechanism includes mounting holes on the side of the first connecting piece, each mounting hole having a fastening bolt inside, each second connecting piece having a threaded hole on its side, one end of each fastening bolt passing through the mounting hole and extending into the corresponding threaded hole, and one end of each fastening bolt being threadedly connected to the corresponding threaded hole.

[0010] Preferably, reinforcing ribs are installed on the outer sides of both the first arc-shaped plate and the second connecting piece.

[0011] Preferably, the inner end faces of the groove are symmetrically provided with arc-shaped limiting grooves, and the inner surfaces of the first arc-shaped plate and the second connecting piece are both equipped with arc-shaped limiting blocks. When the first arc-shaped plate and the second connecting piece are located in the groove, one side of the arc-shaped limiting block extends into the corresponding arc-shaped limiting groove.

[0012] Preferably, when the wedge block extends into the corresponding wedge groove, one end of the arc-shaped skirt contacts and connects with the side of the arc-shaped limiting block.

[0013] Preferably, when the wedge block extends into the corresponding wedge groove, the outer surface of the wedge block and the inner surface of the wedge groove are in clearance fit.

[0014] Preferably, the arc-shaped support plate is made of carbon fiber material and has a mesh structure.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1. The first and second arc-shaped plates can support the outer ring, increasing its structural strength and preventing deformation or damage during use, thus improving its impact resistance.

[0017] 2. The curved support plate can support both sides of the outer ring, which can buffer and disperse the impact force when the outer ring is impacted, prevent the outer ring from breaking, increase the toughness of the outer ring, and improve the performance. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 An impact-resistant and high-toughness bicycle rim includes an outer rim 1. The outer rim 1 has a bushing 16 coaxially arranged inside. The outer surface of the bushing 16 is connected to the inner surface of the outer rim 1 by a number of spokes 2. In actual use, the outer rim 1 is connected to the bicycle by connecting the bushing 16 to the front or rear fork of the bicycle through a bearing. The spokes 2 support the outer rim 1 to prevent deformation.

[0027] like Figure 1 and Figure 4 As shown, the outer side of the outer ring 1 is recessed inward to form a groove 18, and a first arc plate 10 and a second arc plate 12 are provided inside the groove 18. In actual use, the first arc plate 10 and the second arc plate 12 can support the outer ring 1 and increase the structural strength of the outer ring 1, so that the outer ring 1 will not bend or deform.

[0028] It should be noted that, as Figure 4 As shown, reinforcing ribs 9 are installed on the outer sides of both the first arc plate 10 and the second connecting piece 11. The reinforcing ribs 9 can increase the structural strength of the first arc plate 10 and the second arc plate 12 and improve the performance.

[0029] like Figure 1 and Figure 5As shown, the inner end face of the groove 18 is symmetrically provided with arc-shaped limiting grooves 17, and the inner surfaces of the first arc plate 10 and the second connecting piece 11 are both equipped with arc-shaped limiting blocks 4. When the first arc plate 10 and the second connecting piece 11 are located in the groove 18, one side of the arc-shaped limiting block 4 extends into the corresponding arc-shaped limiting groove 17. Through the cooperation of the arc-shaped limiting block 4 and the arc-shaped limiting groove 17, the first arc plate 10 and the second arc plate 12 can be limited, so that the first arc plate 10 and the second arc plate 12 will not rotate relative to the outer ring 1 during use.

[0030] like Figure 1 and Figure 5 As shown, the second arc-shaped plate 12 is symmetrically arranged with the first arc-shaped plate 10, and a second connecting piece 11 is installed at both ends of the first arc-shaped plate 10. A first connecting piece 5 is installed at both ends of the second arc-shaped plate 12. When the inner surfaces of the first arc-shaped plate 10 and the second arc-shaped plate 12 contact the inner wall of the groove 18, the first connecting piece 5 and the corresponding second connecting piece 11 are staggered, and adjacent first connecting pieces 5 and second connecting pieces 11 are connected by a fastening mechanism. The fastening mechanism includes a mounting hole 1 opened on the side of the first connecting piece 5. 4. Each mounting hole 14 is equipped with a fastening bolt 13 inside, and each second connecting piece 11 has a threaded hole 15 on its side. One end of each fastening bolt 13 passes through the mounting hole 14 and extends into the corresponding threaded hole 15, and one end of each fastening bolt 13 is threadedly connected to the corresponding threaded hole 15. In actual use, the first connecting piece 5 and the corresponding second connecting piece 11 can be fixed together by the fastening bolt 13, thereby fixing the first arc plate 10 and the second arc plate 12 firmly.

[0031] like Figure 1 and Figure 6 As shown, arc-shaped support plates 7 are symmetrically provided on both sides of the first arc-shaped plate 10 and the second arc-shaped plate 12. One side of the arc-shaped support plate 7 is in contact with the inner wall of the groove 18. The arc-shaped support plate 7 is made of carbon fiber material and has a mesh structure. In actual use, the arc-shaped support plate 7 can support both sides of the outer ring 1. In this way, the arc-shaped support plate 7 can support both sides of the outer ring 1 and buffer and disperse the impact force received by the outer ring 1, which can prevent the outer ring 1 from cracking due to excessive force and improve toughness.

[0032] like Figure 1 and Figure 2As shown, an arc-shaped skirt 6 extends from one side of each arc-shaped support plate 7, and several wedge blocks 8 are installed on one side of each arc-shaped skirt 6. Several wedge grooves 3 are symmetrically opened on both sides of the inner surface of the first arc-shaped plate 10 and the second arc-shaped plate 12. One side of each wedge block 8 extends into the corresponding wedge groove 3. With the cooperation of the wedge block 8 and the wedge groove 3, the arc-shaped support plate 7 can be connected to the corresponding first arc-shaped plate 10 and second arc-shaped plate 12, which facilitates installation.

[0033] It should be noted that, as Figure 2 As shown, when the wedge block 8 extends into the corresponding wedge groove 3, one end of the arc-shaped skirt 6 contacts and connects with the side of the arc-shaped limiting block 4. In this way, when the first arc plate 10 and the second arc plate 12 are connected to the outer ring 1, the inner surfaces of the first arc plate 10 and the second arc plate 12 will contact the inner wall of the groove 18 through the arc-shaped skirt 6 and the arc-shaped limiting block 4, ensuring sufficient contact and stable installation.

[0034] Specifically, during installation, the operator moves the arc-shaped support plate 7 to one side of the first arc-shaped plate 10 or the second arc-shaped plate 12, and then moves the wedge-shaped block 8 on the arc-shaped skirt 6 connected to the arc-shaped support plate 7 into the corresponding wedge-shaped groove 3 on the first arc-shaped plate 10 or the second arc-shaped plate 12, thereby connecting the arc-shaped support plate 7 with the corresponding first arc-shaped plate 10 or the second arc-shaped plate 12.

[0035] Then, the first arc plate 10 and the second arc plate 12 are moved into the groove 18 on the outer ring 1, so that the first connecting pieces 5 at both ends of the second arc plate 12 extend into the sides of the second connecting pieces 11 at both ends of the first arc plate 10, and the adjacent mounting holes 14 and threaded holes 15 are aligned. Then, the worker inserts one end of the fastening bolt 13 through the mounting hole 14 and screws it into the threaded hole 15 to fix the first arc plate 10 and the second arc plate 12 together, thus fixing the arc support plate 7 in the groove 18. In this way, the arc support plate 7 can support the inner sidewall of the groove 18, and at the same time, it can buffer and disperse the impact force received by the outer ring 1, thereby increasing the toughness of the outer ring 1. At the same time, the first arc plate 10 and the second arc plate 12 can support the outer ring 1, increase the structural strength of the outer ring 1, and improve the impact resistance.

[0036] Furthermore, when the wedge block 8 extends into the corresponding wedge groove 3, the outer surface of the wedge block 8 and the inner surface of the wedge groove 3 are in clearance fit, so that the wedge block 8 will not wobble in the wedge groove 3, thereby ensuring that the arc support plate 7 will not wobble relative to the first arc plate 10 or the second arc plate 12.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
