Description

Technical Field

[0001] This invention relates to the field of automotive anti-skid chains, and more particularly to a lightweight automotive anti-skid chain. Background Technology

[0002] As an important automotive safety device, snow chains primarily enhance vehicle safety in harsh road conditions such as ice, snow, and mud. By increasing the friction between the tires and the ground, snow chains effectively prevent vehicle slippage and loss of control, and are widely used, especially on icy and snowy roads, providing sufficient grip for the tires. However, the weight of snow chains increases the unsprung weight of the vehicle's suspension and the overall vehicle weight, affecting vehicle stability and handling, and causing the tires to bear a greater load. This not only increases fuel consumption but also adds to the vehicle's load, making driving on complex road conditions such as slopes more difficult. Therefore, there is a need for a lightweight automotive snow chain that reduces the increased load on the tires while ensuring sufficient durability. Summary of the Invention

Detailed Implementation

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0027] Example 1

[0028] This invention provides a lightweight automotive anti-skid chain, hereinafter referred to as the anti-skid chain. Figures 1-6As shown, it includes a long chain group 11, a first single chain 12, a second single chain 13, a long rope group 21, a short rope group 31, a third single chain 32, a hook 41, a rope reel 42, a rope 43, a hanging block 44, a guard bar 51, and a baffle 52; it has several long chain groups 11; each long chain group 11 has a first single chain 12 fixed to its rear side; each long chain group 11 has a second single chain 13 fixed to its front side; each pair of adjacent first single chains 12 is connected to a long rope group 21 that is easy to replace; each pair of adjacent second single chains 13 has a short rope group 31 that is easy to replace on its opposite side; each pair of adjacent short rope groups 31 is connected to a third single chain. 32; A hook 41 is fixedly attached to the first single chain 12 on the left; A hook 41 is also fixedly attached to the first second single chain 13 on the left; A rope winder 42 is fixedly attached to the first second single chain 13 on the right; A rope winder 42 is also fixedly attached to the first second single chain 13 on the right; A rope cable 43 is wound around the winding part of each of the two rope winders 42; A hanging block 44 is fixedly attached to each of the two rope cables 43; A guard bar 51 is fixedly attached to each second single chain 13, and the guard bar 51 is a reverse buckle structure with both ends bent downwards; A baffle 52 is fixedly attached to each guard bar 51; Each baffle 52 is a downward retracting blade structure.

[0029] like Figure 1 and Figure 5 As shown, the long rope assembly 21 consists of a long fiber rope 211, a first threaded insert 212, a first threaded sleeve 213, and a long nylon sleeve 214; each end of the long fiber rope 211 is fixed with a first threaded insert 212; each of the two first threaded inserts 212 is screwed with a first threaded sleeve 213; the two first threaded sleeves 213 are respectively fixed with corresponding first single chains 12; the long fiber rope 211 is covered with a long nylon sleeve 214.

[0030] like Figure 1 and Figure 6 As shown, the short rope assembly 31 consists of a short fiber rope 311, a second threaded insert 312, a second threaded sleeve 313, and a short nylon sleeve 314; each end of the short fiber rope 311 is fixed with a second threaded insert 312; each of the two second threaded inserts 312 is screwed with a second threaded sleeve 313; the two second threaded sleeves 313 are respectively fixed with corresponding second single chains 13; a short nylon sleeve 314 is sleeved on the outside of the short fiber rope 311.

[0031] When using this snow chain, the user should first lay it out flat with the long rope group 21 facing the inside of the tire and the short rope group 31 facing the outside of the tire. Then, place the long chain group 11 in the middle of the snow chain on top of the tire tread. Pull down the long chain groups 11 on both sides until they are close to the tire tread. Bring the hook 41 on the left long chain group 11 and the rope winder 42 on the right long chain group 11 together at the bottom of the tire tread. The user should then hang the two hooks... 44 are respectively hung on the hooks 41 on the same side, and the rope reel 42 is operated to tighten the rope 43. At the same time, the rope 43 pulls the hanging block 44 to firmly hook and lock the corresponding hook 41. At this time, all the long rope groups 21 are wrapped tightly against the tire sidewall on the inner side of the vehicle body, and all the short rope groups 31 are wrapped tightly against the tire sidewall on the outer side of the vehicle body. The baffle 52 on the second single chain 13 is in a state of being pulled towards the wheel core of the tire, thus completing the quick installation of this anti-skid chain.

[0032] When the user drives the vehicle and the snow chain rotates with the tire, the long rope group 21 is mainly composed of long fiber ropes 211 and long nylon sleeves 214, and the short rope group 31 is mainly composed of short fiber ropes 311 and short nylon sleeves 314. Compared with the traditional chain connection structure, using fiber ropes as the connection structure can significantly reduce the load on the tire, achieving the purpose of lightweighting. The long rope group 21 located on the inner side of the tire and the short rope group 31 located on the outer side of the tire do not contact the ground, so there is no need to worry about the wear and tear caused by long-term friction between the long rope group 21 and the short rope group 31 and the ground. Only when the tire sidewall comes into contact with an unidentified protruding foreign object on the ground or scrapes against the curb, the long rope group 21... Scratches and wear only occur with the short rope group 31. However, the long nylon sleeves 214 and 314 in the long rope group 21 and short rope group 31 respectively provide scratch protection for the corresponding long fiber ropes 211 and short fiber ropes 311. Therefore, there is no need to worry about damage to the long fiber ropes 211 and short fiber ropes 311, which are the connecting structures. In addition, even if the tire sidewall rubs against the curb, the guard bar 51 and baffle 52 on the second single chain 13 will contact the curb first, reducing the wear caused by rubbing against the short rope group 31. At the same time, the third single chain 32 and the short rope group 31 together serve as a connecting structure, which can further strengthen the structural strength of the connecting structure.

[0033] During driving, when there are a large number of shrub roots and branches attached to the tire sidewall, the baffle 52 on the second single chain 13 can easily cut off the shrub roots and branches with the help of the strong torque provided by the tire as the tire rotates, thus preventing the shrub roots and branches from scratching the tire sidewall. Furthermore, since the baffle 52 is in a state of being folded towards the tire's wheel center, it can prevent the baffle 52 from causing injury to pedestrians during continuous rotation.

[0034] In addition, during routine maintenance of this anti-skid chain, if the user finds that the long nylon sleeve 214 on a certain long rope group 21 is severely worn, the user only needs to remove the first threaded insert 212 from the first threaded sleeve 213 to quickly replace the long nylon sleeve 214 of the long rope group 21. If the user finds that the short nylon sleeve 314 on a certain short rope group 31 is severely worn, the user only needs to remove the second threaded insert 312 from the second threaded sleeve 313 to quickly replace the short nylon sleeve 314 of the short rope group 31. There is no need to replace the entire anti-skid chain, thus improving the service life of this anti-skid chain.

[0035] Example 2, based on Example 1 above, as follows: Figures 1-7 As shown, each long chain assembly 11 in this embodiment consists of a short chain 111, an aluminum alloy rope 112, and a nylon protective plate 113; each end of the short chain 111 is fixed with an aluminum alloy rope 112; one aluminum alloy rope 112 of the short chain 111 is fixed with a corresponding first single chain 12; the other aluminum alloy rope 112 of the short chain 111 is fixed with a corresponding second single chain 13; a nylon protective plate 113 is fixed to the upper side of each aluminum alloy rope 112; since the long chain assembly 11 is installed on the tire, only the short chain 111 located in the middle of the long chain assembly 11 is visible. The tire chain 111, which is more wear-resistant, is in close contact with the ground for a long time. The aluminum alloy ropes 112 located on both sides of the long chain group 11 only come into contact with the tire shoulders on both sides. Therefore, the aluminum alloy ropes 112 have less contact with the ground. The lighter aluminum alloy ropes 112 are connected to the first single chain 12 or the second single chain 13 on the side, which can further reduce the overall weight of the anti-skid chain. Even if the tire shoulder hits the road shoulder, the nylon protective plate 113 can provide scratch protection for the aluminum alloy ropes 112.

[0036] Example 3, based on Example 1 above, as follows: Figures 1-6 and Figure 8As shown, in this embodiment, each of the four first single chains 12 is connected to a bidirectional hanging rope group 61; each of the four second single chains 13 is also connected to a bidirectional hanging rope group 61; each bidirectional hanging rope group 61 consists of an elastic pull rope 611 and a locking hook 612; a locking hook 612 is fixed to each end of the elastic pull rope 611; the bidirectional hanging rope group 61 on the first single chain 12 is connected to the first single chain 12 by a locking hook 612; the bidirectional hanging rope group 61 on the second single chain 13 is connected to the second single chain 13 by a locking hook 612; after the user installs the anti-skid chain on the tire, he pulls the bidirectional hanging rope group 61 on the first single chain 12 to stretch the elastic pull rope 611, and hangs the other locking hook 612 of the elastic pull rope 611 on the axis symmetrically opposite to the wheel core of the tire. On one of the first single chains 12, the elastic cord 611 is kept in a stretched state. The stretched elastic cord 611 pulls the first single chains 12 on both sides toward the tire's wheel center, and pulls the bidirectional hanging rope group 61 on the second single chain 13 to keep the elastic cord 611 in a stretched state. The other hook 612 of the elastic cord 611 is hung on a second single chain 13 that is symmetrical about the wheel center. At this time, the elastic cord 611 is also kept in a stretched state. The stretched elastic cord 611 pulls the second single chains 13 on both sides toward the tire's wheel center, so that all the first single chains 12 and the corresponding second single chains 13 pull the long chain group 11 together to firmly stick it to the tire tread. This prevents the long chain group 11 from frequently sliding and displacing with the tire tread during the tire's operation, which would cause the long chain group 11 to severely scratch the tire tread.

[0037] Example 4, based on Example 1 above, as follows: Figures 1-6 and Figure 9 As shown, in this embodiment, the long chain group 11 is composed of two L-shaped chains forming a rhombus structure; a steel rope 14 is fixedly connected between each pair of adjacent rhombus structure long chain groups 11; when the user installs this anti-skid chain on the tire, compared with the long chain group 11 composed of a single chain described in Embodiment 1, the rhombus structure long chain group 11 and steel rope 14 described in this embodiment can increase the contact area with the tire surface, thereby increasing the anti-skid effect during tire driving. The anti-skid chain described in this embodiment is suitable for providing high-strength anti-skid grounding effect for the tires of heavy vehicles, allowing heavy vehicles to have excellent anti-skid grip performance.

[0038] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
