Description

Technical Field

[0001] This utility model relates to the field of vehicle safety equipment, and in particular to a lightweight anti-skid chain for vehicles. Background Technology

[0002] With the increasing popularity of two-wheeled light vehicles, the demand for all-weather travel is growing. On icy or snowy roads in winter, or in adverse road conditions, the traction between the tires and the ground decreases sharply, making the vehicle prone to skidding, sideslipping, or even falling, seriously threatening user safety. Snow chains are an effective solution to this problem.

[0003] Currently, the snow chains available on the market for two-wheeled vehicles mainly borrow or simplify the design of automotive snow chains, and generally suffer from the following technical defects: Poor adaptability and fixing reliability: Most products use simple hooks or spring fasteners for connection. Two-wheeled vehicles have vastly different tire sizes and tread patterns, and the internal space of the wheel hub is extremely small, filled with brake calipers, shock absorbers, and various wiring harnesses. Traditional side-hook fixing methods are not only difficult to install, but also prone to interference with vehicle components. More seriously, under high-speed rotation and severe vibration, these fasteners are prone to loosening and falling off. Once the snow chain falls off while driving, it may get caught in the wheel or braking system, causing serious secondary accidents.

[0004] Therefore, there is an urgent need in the art for a snow chain device specifically designed for two-wheeled light vehicles that is easy to install, reliably fixed, can balance longitudinal grip and lateral stability, and is tire-friendly. This invention aims to completely solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a lightweight vehicle anti-skid chain that is easy to install, highly versatile, avoids interference between anti-skid chain accessories and vehicle parts, and improves the safety performance of the anti-skid chain.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A lightweight vehicle snow chain includes a main chain and side ropes. The main chain is composed of multiple metal links connected in a diamond-shaped mesh structure and covers the tread area of ​​the tire. There are two side ropes, which are fixedly connected to both sides of the main chain along the rolling direction of the tire. The side ropes are attached to the sidewall of the tire. The chain also includes elastic fasteners, at least two of which have hook-shaped parts at both ends. When the snow chain is installed, the elastic fasteners pass through the inner space of the wheel hub, and the hook-shaped parts at both ends hook and connect to the side ropes on both sides.

[0008] Unlike four-wheeled vehicles, two-wheeled vehicles cannot use the locking mechanisms, chains, and rubber handles of traditional automotive snow chains, as these devices interfere with the vehicle's components and affect driving safety. This solution cleverly utilizes the relatively open space inside the wheel hub by using elastic fasteners to tighten the ropes on both sides. Through radial tightening from the center, it provides a uniform and powerful preload, fundamentally eliminating the risk of traditional side hooks loosening due to vibration. This significantly improves safety. This installation path perfectly avoids the complex braking system, shock absorbers, and various wiring harnesses outside the two-wheeled vehicle's wheel hub, making this snow chain compatible with most different models of electric bicycles, motorcycles, and bicycles. It solves the industry pain point of traditional side hook snow chains, where the instability of the locking mechanism leads to low driving safety. This lightweight vehicle snow chain is easy to install, highly versatile, avoids interference between snow chain components and vehicle parts, and improves the safety performance of the snow chain.

[0009] Preferably, the main chain includes friction chains and connecting rings. The links of the friction chains are torsion links, and the connecting rings connect four friction chains to form a diamond-shaped grid structure of the main chain. By using torsion links as friction chains, excellent tire contact is achieved. The torsion links can twist and deform with the curvature of the tire, thus tightly wrapping the tire surface. During driving, the torsion links change with the contact area between the tire and the ground, ensuring that the contact part of the snow chain, i.e., the friction chain, can fit the tire tread with the largest possible area, thereby providing uniform and strong grip. At the same time, it avoids the "washboard effect" that may occur with cross links, improving the stability of driving on icy and snowy roads.

[0010] As a preferred option, flexible fasteners include springs. The advantages of springs are that they provide maximum tensile travel and extremely strong restoring force. Springs are also robust and durable, with excellent fatigue resistance, and can withstand long-term, frequent disassembly and assembly and use in harsh environments, making them suitable for applications that require ultimate reliability and ultra-long service life.

[0011] As a preferred option, flexible fasteners include high-strength rubber strips. The advantages of high-strength rubber strips include lightweight, cost-effectiveness, and ergonomics. The rubber strips are also soft, eliminating concerns about metal fatigue and breakage. They offer a comfortable feel and will not scratch users' fingers or vehicle parts during installation, providing a safer and more user-friendly experience.

[0012] Preferably, the resilient fastener comprises a braided tape with built-in elastic fibers. The advantage of the braided tape is that it combines high strength and flexibility. The outer braided tape provides excellent abrasion resistance and tear resistance, protecting the inner elastic fibers, while the inner elastic fibers provide the required elastic preload. This structure is durable and easy to operate.

[0013] Preferably, a hook plate is also included. The hook plate comprises an attachment part and a fixing part. The fixing part is connected to the side rope, and the attachment part is connected to the end of the friction chain. By adding the hook plate, this solution optimizes the force transmission path. The fixing part of the hook plate is firmly connected to the side rope, and the attachment part is connected to the end of the friction chain. This allows the tension on the friction chain to be evenly distributed to the side rope through the robust metal hook plate, avoiding localized stress concentration on the side rope that could lead to strain or wear. This significantly improves the structural strength and overall durability of key connection points.

[0014] Preferably, the product also includes a buckle plate and buckle beads. The buckle plate is located at one end of the side cord, and the buckle beads are located at the other end. There are at least two buckle beads. Through the combination of the buckle plate and multiple buckle beads, the length of the side cord is adjustable. This allows a single product model to be precisely adapted to tires of different diameters by fine-tuning the length, greatly expanding the product's applicability, reducing manufacturing and inventory costs, and enhancing market competitiveness.

[0015] Furthermore, it includes auxiliary chains. The auxiliary chains have twisted links and are straight chains. Each end of the auxiliary chain is connected to one of the two side ropes, and there is an auxiliary chain at each end of the main chain. The connection method using buckles and beads has a significant drawback: a large gap is created in the connection area between the buckle and the bead, which manifests as bouncing during operation. However, by placing an auxiliary chain at each end of the main chain, this gap is effectively reduced, improving driving stability.

[0016] Preferably, the side rope comprises a steel wire rope with a plastic coating on its surface. The steel wire rope has a highly flexible 7x19 structure. The outer plastic coating effectively protects the internal steel wire rope from corrosion by moisture, salt, etc., extending its lifespan. Secondly, the soft plastic layer prevents the metal rope from directly rubbing against and damaging the tire sidewall and rim. This type of steel wire rope and plastic coating structure provides a better feel, making it easier for users to install and operate.

[0017] Preferably, the coating layer is made of polyethylene. Polyethylene has excellent wear resistance, high elasticity, low temperature resistance, and oil resistance, perfectly meeting the needs of anti-skid chains in various harsh road conditions, ensuring the long-term durability of the coating layer and the overall reliability of the product.

[0018] In summary, this type of lightweight vehicle snow chain is easy to install, highly versatile, avoids interference between snow chain components and vehicle parts, and greatly improves the safety performance of the snow chain. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] A lightweight vehicle snow chain includes a main chain body 1 and side ropes 2. The main chain body 1 is composed of multiple metal links connected in a diamond grid structure. The main chain body covers the tread area of ​​the tire 8. There are two side ropes 2, which are respectively fixedly connected to the two sides of the main chain body 1 along the rolling direction of the tire 8. The side ropes are in contact with the sidewall of the tire. The chain also includes elastic fasteners 3, of which there are at least two. The elastic fasteners 3 have hook-shaped parts 32 at both ends. When the snow chain is installed, the elastic fasteners 3 pass through the inner space of the wheel hub 9, and the hook-shaped parts 32 at both ends hook and connect to the side ropes 2 on both sides.

[0027] Reference Appendix Figure 2 Unlike four-wheeled vehicles, two-wheeled vehicles cannot use the locking mechanisms, chains, and rubber handles of traditional automotive snow chains due to their axle design. These devices would interfere with the components of the two-wheeled vehicle, affecting driving safety. This solution cleverly utilizes the relatively open space inside the wheel hub 9 by using elastic fasteners 3 to tighten the ropes 2 on both sides. Through radial tightening from the center, it provides a uniform and powerful preload, fundamentally eliminating the risk of traditional side hooks loosening due to vibration. This significantly improves safety. This installation path perfectly avoids the complex braking system, shock absorbers, and various wiring harnesses outside the wheel hub 9 of the two-wheeled vehicle. This allows the snow chain to be used on most different models of electric bicycles, motorcycles, and bicycles, solving the industry pain point of low driving safety caused by the instability of the locking device in traditional side hook snow chains. This lightweight vehicle snow chain is easy to install, highly versatile, avoids interference between snow chain components and vehicle parts, and improves the safety performance of the snow chain.

[0028] Reference Appendix Figure 1 and appendix Figure 2 The main chain 1 includes friction chains 11 and connecting rings 12. The links of the friction chains 11 are torsion links, and the connecting rings 12 connect four friction chains 11 to form a diamond-shaped grid structure of the main chain 1. By using torsion links as friction chains 11, excellent tire fit is achieved. The torsion links can twist and deform with the curvature of the tire, thus tightly wrapping the tire surface. During driving, the torsion links change with the contact area between the tire and the ground, ensuring that the ground contact part of the anti-skid chain, i.e., the friction chain 11, can fit the tire tread with the largest possible area, thereby providing uniform and strong grip, while avoiding the "washboard effect" that may occur with cross links, thus improving the stability of driving on icy and snowy roads.

[0029] Reference Appendix Figure 3 As a first embodiment of the resilient fastener, the resilient fastener 3 includes a spring 31. The advantage of the spring 31 is that it can provide maximum tensile stroke and extremely strong restoring force. In addition, the spring 31 is robust and durable, has excellent fatigue resistance, and can withstand long-term, frequent disassembly and assembly and use in harsh environments. It is suitable for application scenarios that pursue ultimate reliability and ultra-long service life.

[0030] In addition, as a second embodiment of the resilient fastener, the resilient fastener 3 includes a high-strength rubber strip (not shown in the figure). The advantages of the high-strength rubber strip include lightweight, cost-effectiveness, and ergonomics. Furthermore, the rubber strip is soft, eliminating concerns about metal fatigue fracture, providing a comfortable feel, and preventing scratches to the user's fingers or vehicle parts during installation, thus offering a safer and more user-friendly experience.

[0031] As a third embodiment of the resilient fastener, the resilient fastener 3 includes a braided tape (not shown) with built-in elastic fibers. The advantage of the braided tape is that it combines high strength and flexibility. The outer braided tape provides excellent abrasion resistance and tear resistance, protecting the inner elastic fibers, while the inner elastic fibers provide the required elastic preload. This structure is durable and easy to operate.

[0032] Preferably, a hook plate 4 is also included. The hook plate 4 includes an attachment part 41 and a fixing part 42. The fixing part 42 is connected to the side rope 2, and the attachment part 41 is connected to the end of the friction chain 11. By adding the hook plate 4, this solution optimizes the force transmission path. The fixing part 42 of the hook plate 4 is firmly connected to the side rope 2, and the attachment part 41 is connected to the end of the friction chain 11, so that the tension on the friction chain 11 can be evenly distributed to the side rope 2 through the sturdy metal hook plate 4. This avoids local stress concentration on the side rope 2, which can cause it to be strained or worn, and significantly improves the structural strength and overall durability of the key connection points.

[0033] Preferably, the product also includes a buckle plate 5 and buckle beads 6. The buckle plate 5 is located at one end of the side rope 2, and the buckle beads 6 are located at the other end of the side rope 2. There are at least two buckle beads 6. Through the cooperative design of the buckle plate 5 and multiple buckle beads 6, the length of the side rope 2 is adjustable. This allows a single model of product to be precisely adapted to tires of different diameters by fine-tuning the length, greatly expanding the product's applicability, reducing manufacturing and inventory costs, and enhancing market competitiveness.

[0034] Reference Appendix Figure 3 It also includes an auxiliary chain 7, whose links are twisted links. The auxiliary chain 7 is a straight chain, and its two ends are connected to two side ropes 2 respectively. One auxiliary chain 7 is provided at each end of the main chain body 1. The connection method using buckle plates 5 and bead 6 has a significant drawback: a large gap is created in the connection area between buckle plates 5 and bead 6, which manifests as bouncing during operation. However, by providing an auxiliary chain 7 at each end of the main chain body 1, this gap is effectively reduced, improving driving stability.

[0035] Preferably, the side rope 2 includes a steel wire rope 21, the surface of which is provided with a plastic coating layer 22. (See attached document) Figure 4 The steel wire rope 21 has a highly flexible 7×19 structure. The outer plastic coating layer 22 firstly effectively protects the inner steel wire rope 21 from corrosion by moisture, salt, etc., thus extending its service life. Secondly, the soft plastic layer avoids direct friction and damage between the metal rope and the tire sidewall and wheel hub 9. This steel wire rope 21 and the plastic coating structure provide a better feel, making it easier for users to install and operate.

[0036] Preferably, the plastic coating layer 22 is made of polyethylene. Polyethylene has excellent wear resistance, high elasticity, low temperature resistance and oil resistance, which perfectly meets the needs of anti-skid chains in various harsh road conditions, ensuring the long-term durability of the plastic coating layer 22 and the overall reliability of the product.

[0037] In summary, this type of lightweight vehicle snow chain is easy to install, highly versatile, avoids interference between snow chain components and vehicle parts, and greatly improves the safety performance of the snow chain.

[0038] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
