Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of anti-skid chain technology, and more specifically to an electric vehicle anti-skid chain with a tightening and adjusting structure. Background Technology
[0002] Electric vehicles have become an important means of transportation for people's daily travel due to their convenience and environmental friendliness. In urban roads, electric vehicles can maneuver flexibly and alleviate traffic congestion, especially during rush hour. However, in winter or in severe weather conditions, such as icy roads, snow, or water accumulation, the safety of electric vehicle operation is challenged. Because electric vehicle tires are relatively narrow and have a small contact area with the ground, they are prone to slipping on wet and slippery surfaces, leading to loss of control, falls, and other safety accidents that threaten the life and property safety of riders.
[0003] To address the issue of slippery surfaces for electric vehicles, snow chains have been designed to increase the contact area between the tires and the ground. Traditional snow chains are typically made of iron or rubber chains and are installed on the tires to increase the friction between the tires and the ground, thereby improving the vehicle's stability on slippery surfaces.
[0004] Inconveniently installed snow chains not only waste riders' time and energy but can also affect their normal travel. Furthermore, if the snow chains are installed too loosely, they are prone to loosening and falling off during riding, failing to provide effective anti-slip protection; while if installed too tightly, they may damage the tires or rims. Therefore, to improve the ease of use and safety of electric vehicle snow chains, the development of snow chains with adjustable tightening mechanisms has become an inevitable trend. This structure allows riders to quickly and easily adjust the tightness of the snow chains according to tire size and actual needs, ensuring a close fit between the snow chains and the tires, providing excellent anti-slip performance under various road conditions, while also facilitating installation and removal.
[0005] A search revealed Chinese Patent Publication No. CN201820425666.5F: a nailed square chain anti-skid chain; comprising an anti-skid chain body, a first torsion chain movably mounted at one end of the anti-skid chain body, a second torsion chain movably mounted at the other end of the first torsion chain, an F-nailed square chain between the first and second torsion chains, an F-nail fixedly mounted on the outer surface of the front end of the F-nailed square chain near the top, and a lower connecting post fixedly mounted at the bottom end of the F-nailed square chain;
[0006] While the device in the aforementioned patent can achieve an anti-slip effect during use, the size of the F-pin in the patent is larger than the size of the F-pin square chain when the tire contacts the ground. This causes the F-pin to squeeze the tire inward, resulting in greater pressure on the tire and causing localized damage or even punctures. Consequently, the quality of the tire cannot be adequately guaranteed. Utility Model Content
[0007] The purpose of this invention is to provide an electric vehicle anti-skid chain with a tightening and adjusting structure. In this device, the two ends of multiple transverse chains are respectively connected to a first chain and a mating chain. The first chain and the mating chain are located on both sides of the tire. The multiple transverse chains bend along the surface of the tire, thereby effectively ensuring the fit between the transverse chains and the tire surface. The connection between the multiple mating chains is achieved through the adjusting buckle at the end of the mating chain. When it is necessary to adjust the tightening effect of the mating chain, the adjusting buckle is turned by turning the handle to effectively achieve the tightening effect and ensure the stability of the chain during use. This solves the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] An electric vehicle anti-skid chain with a tightening and adjusting structure includes multiple first mating chains and second mating chains; each of the first and second mating chains consists of multiple closed loops; multiple transverse chains are fitted onto each of the first and second mating chains; wherein, an adjusting buckle is movably installed at one end of each of the first and second mating chains; the adjusting buckle is L-shaped; and an ear plate for easy bolt installation is fitted onto the end of the adjusting buckle away from the first or second mating chain.
[0010] The adjusting buckle has a slot on the side near the first or second mating chain; the adjusting buckle also has a hexagonal groove.
[0011] As a further technical solution of this utility model, the ends of the plurality of transverse chains away from the first and second mating chains are fitted with the first chain; the first chain passes through the plurality of transverse chains; and the two ends of the first chain are respectively provided with a first hook and a second hook.
[0012] As a further technical solution of this utility model, both the first hook and the second hook are provided with round holes to facilitate the bolt penetration; the outer wall of the first hook is provided with a rectangular surface, and the inner wall of the second hook is provided with a rectangular surface.
[0013] As a further technical solution of this utility model, the outer wall of the first hook is fitted with the inner wall of the second hook, and can be detachably installed by bolts;
[0014] As a further technical solution of this utility model, the bolts on the adjusting buckles at the ends of the first and second mating chains engage with the second closed rings at the ends of the first and second mating chains;
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In use, multiple first mating chains and second mating chains are connected sequentially, and the connected first mating chains and second mating chains are placed on the surface of the tire along with the transverse chain, with the multiple first mating chains and second mating chains located on one side of the tire;
[0017] 2. In this utility model, after multiple first mating chains and second mating chains are placed with transverse chains, the ends of multiple transverse chains away from the mating chains are then installed with the first chains. During installation, the two ends of the first chain are fitted together by the outer wall of the first hook and the inner wall of the second hook, and then fixed with bolts, thereby ensuring the tight connection of the first chain to the multiple transverse chains.
[0018] 3. In this utility model, after installation, when the anti-skid chain is in a loose state, the adjusting buckle at the end of the first or second mating chain can be rotated by wrench to rotate the bolt on the ear plate of the adjusting buckle to the second closed ring at the end, and the bolt is used to fix it to the second closed ring to prevent loosening. If rotating one adjusting buckle cannot effectively tighten it, then rotate one or more other adjusting buckles to ensure a tight anti-skid effect on the tire. Attached Figure Description
