Description

Technical Field

[0001] This utility model belongs to the technical field of anti-skid tire covers, and in particular relates to an anti-skid tire cover for icy roads. Background Technology

[0002] When vehicles encounter severe weather such as heavy snow or freezing rain, the resistance between the wheels and the ground decreases due to the rain and snow, which can easily lead to vehicle slippage, loss of control, and unstable driving. In severe cases, it can even cause rollovers and accidents. Therefore, a tire cover is needed to increase the friction between the tire and the icy road surface.

[0003] Patent application CN202421176675.7 discloses an anti-skid tire cover for icy roads, comprising an anti-skid cover fitted onto the outside of a tire and a support plate disposed on one side of the tire; the support plate is detachably connected to the wheel hub and rotates synchronously; the anti-skid cover includes a high-abrasion coated layer near the tire and an outer support layer away from the tire, the outer support layer having multiple recessed filling pits extending away from the tire, each filling pit containing a filler, and the opening of the filling pits being sealed by the high-abrasion coated layer; the anti-skid cover is fixedly connected to the support plate and rotates synchronously. Unlike the anti-skid chain structure commonly used in existing vehicles, this device is more suitable for sightseeing vehicles. It is applied by fitting onto the outside of the sightseeing vehicle's tires, and the convex portion of the filling pits achieves a shock-absorbing effect, resulting in less undulation during driving and a better experience for passengers.

[0004] Existing technologies reduce the undulation during vehicle movement by filling in the bulges, but they still have shortcomings: First, existing technology can only be installed and fixed for tires of a single size, and cannot be adapted to the width and thickness of the tire, resulting in poor overall adaptability of the anti-skid tire cover and insufficient practicality. Secondly, when encountering roads with a lot of snow, the anti-skid grooves on the existing anti-skid tire covers reduce the anti-skid properties between the tire and the snow, thus reducing the overall anti-skid performance of the tire and making it easier for the vehicle to lose control. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides an anti-skid tire cover for icy roads. Through the arrangement of components such as the first adjusting strip, this invention can adaptively adjust to the size, width, and thickness of the tire; through the pattern of the irregularly shaped grooves and the gradually deepening grooves, it can effectively compress the ice and snow particles inside the grooves, creating reverse resistance to the rotation of the anti-skid strip.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-skid tire cover for icy roads, comprising a fixed disc, wherein multiple anti-skid strips are slidably arranged in a ring on the outside of the fixed disc, and multiple irregular grooves are provided on the outer circumferential surface of each anti-skid strip, wherein the depth of each irregular groove gradually increases along its rotation direction, and an anti-skid protrusion is provided on the outer circumferential surface between every two irregular grooves, wherein the spike of each anti-skid protrusion is in the same rotation direction as the anti-skid strip.

[0007] Optionally, a groove is provided on the outer wall of the fixed plate, and a first adjusting strip is hinged to one end of each anti-slip strip. A first through hole is provided on one side of each first adjusting strip on the outer circumference of the fixed plate, and one end of each first adjusting strip is slidably connected to its adjacent first through hole.

[0008] Optionally, each of the first adjusting strips has a plurality of first snap-fit ​​holes on its outer side wall, and each of the first through holes has a plurality of first snap-fit ​​bolts on one side of the side wall of the fixing plate. Each of the first snap-fit ​​bolts passes through the fixing plate and the first snap-fit ​​hole adjacent to it, thereby limiting the first adjusting strip inside the first through hole.

[0009] Optionally, each of the anti-slip strips is hinged to a second adjusting strip at the other end, and each of the second adjusting strips has a second through hole on one side of the side wall of the first adjusting strip, and one end of each of the second adjusting strips is slidably connected to the second through hole on one side.

[0010] Optionally, each of the second adjusting strips has a plurality of second snap-fit ​​holes on its sidewall, and each of the second through holes has a connecting block on both sides of the first adjusting strip. One of the connecting blocks has a plurality of second snap-fit ​​bolts on one side, and each of the second snap-fit ​​bolts passes through the adjacent connecting block and the second snap-fit ​​hole to limit one end of the second adjusting strip inside the second through hole.

[0011] Optionally, each of the anti-slip strips has multiple anti-slip rubber strips on its inner sidewall.

[0012] Optionally, sound-absorbing cotton is provided on the inner wall of the anti-slip strip between every two adjacent anti-slip strips.

[0013] Optionally, the groove has multiple sliding rods arranged in a ring shape inside, and each sliding rod has a limit block at one end that passes through the fixed plate. Each limit block has a nut hole on one side wall.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: This utility model, through the setting of components such as anti-slip strip, first adjustment strip and second adjustment strip, can be adaptively adjusted according to the size, width and thickness of the tire, so that the anti-slip pattern on the upper surface of the anti-slip strip can be in the center of the tire, improving the adaptability of the device while ensuring the anti-slip performance of the anti-slip tire cover on the tire. This invention, through the design of irregular grooves and anti-slip protrusions, effectively compresses the ice and snow particles inside the irregular grooves as the anti-slip strip rotates with the tire. This creates a reverse resistance to the rotation of the anti-slip strip, thereby generating a thrust that propels the anti-slip strip forward and, in turn, a thrust that propels the tire to rotate, further improving the overall anti-slip effect of the tire cover.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an anti-skid tire cover for icy roads includes a fixed plate 10. Multiple anti-skid strips 11 are slidably arranged in a ring around the outside of the fixed plate 10. Each anti-skid strip 11 has multiple irregularly shaped grooves 12 on its outer circumferential surface. The depth of each irregularly shaped groove 12 gradually increases along its rotation direction. The overall shape of the irregularly shaped groove 12 is as shown in the figure. Figure 5 As shown, the anti-skid strip 11 has multiple interconnected triangular grooves inside. After the anti-skid strip 11 is installed on the outside of the tire, when the vehicle is traveling on an icy or snowy road, the accumulated snow will compress the snow particles into the grooves 12 under the action of the vehicle's own weight, forming a mutual sliding restriction between the road surface and the anti-skid strip 11, allowing the vehicle to travel on the icy or snowy road. When the snow or ice is thick and the vehicle slips, the tire will cause the anti-skid strip 11 and the grooves 12 to slide relative to the snow and ice on the road surface. At this time, the snow particles compressed inside the grooves 12 will undergo a secondary compression phenomenon. The thinner snow particles inside the grooves 12 will gradually move and compress into the deeper grooves 12. The density of the snow particles after secondary compression will gradually increase under the action of external compression, increasing their hardness and thus providing greater resistance to the relative sliding between the anti-skid strip 11 and the road surface, thereby allowing the anti-skid strip 11 and the tire to get rid of the slipping problem.

[0019] Anti-slip protrusions 13 are provided on the outer surface of the anti-slip strip 11 between every two irregular grooves 12. The spikes of each anti-slip protrusion 13 are in the same direction of rotation as the anti-slip strip 11. The anti-slip protrusions 13 are made of hard material. When the anti-slip protrusions 13 rotate with the anti-slip strip 11 and the tire, their spikes first contact the road surface. When the road surface is icy, the spikes will puncture the ice layer, increasing the roughness of the smooth ice layer. The anti-slip protrusions 13 will also guide the broken ice fragments into the irregular grooves 12 on both sides, causing the ice fragments to be compressed inside the irregular grooves 12, thereby forming a reverse support for the anti-slip strip 11 and improving the anti-slip performance of the anti-slip strip 11.

[0020] Furthermore, such as Figure 1 and Figure 2As shown, a groove 15 is provided on the outer wall of the fixed plate 10. One end of each anti-slip strip 11 is hinged to a first adjusting strip 14. One side of each first adjusting strip 14 is provided with a first through hole 16 on the outer circumference of the fixed plate 10. One end of each first adjusting strip 14 is slidably connected to its adjacent first through hole 16. Multiple first snap-fit ​​holes 17 are provided on the outer wall of each first adjusting strip 14. Multiple first snap-fit ​​bolts 18 are provided on one side of each first through hole 16 on the side wall of the fixed plate 10. All bolts 18 pass through the fixing plate 10 and the adjacent first snap-fit ​​hole 17, forming a limit on the first adjusting strip 14 inside the first through hole 16. During installation, each time one end of the first adjusting strip 14 is passed through the first through hole 16 on one side, and the distance between the anti-slip strip 11 and the fixing plate 10 is adjusted by pulling one end of the first adjusting strip 14. Then, the multiple first snap-fit ​​bolts 18 on one side of the first adjusting strip 14 are tightened so that the first snap-fit ​​bolts 18 pass through the fixing plate 10 and the first snap-fit ​​hole 17 to fix the first adjusting strip 14 inside the first through hole 16.

[0021] Furthermore, such as Figure 1 and Figure 2 As shown, each anti-slip strip 11 has a second adjusting strip 19 hinged to its other end. Each second adjusting strip 19 has a second through hole 28 on one side of the side wall of the first adjusting strip 14. One end of each second adjusting strip 19 is slidably connected to the second through hole 28 on one side. Each second adjusting strip 19 has multiple second snap-fit ​​holes 20 on its side wall. Each second through hole 28 has a connecting block 21 on both sides of the side wall of the first adjusting strip 14. One side of one of the connecting blocks 21 has multiple second snap-fit ​​bolts 22. Each second snap-fit ​​bolt 22 passes through the adjacent connecting block 21 and the second snap-fit ​​hole 20, thus limiting one end of the second adjusting strip 19 inside the second through hole 28.

[0022] During installation, the anti-skid strip 11 is placed on the outside of the tire. Then, one end of the second adjusting strip 19 is pulled so that one end of the second adjusting strip 19 passes through the second through hole 28 on the side wall of the first adjusting strip 14, which is indirectly connected to it. Then, one end of the second adjusting strip 19 and one end of the first adjusting strip 14 connected to the anti-skid strip 11 are pulled so that the tread pattern on the upper surface of the anti-skid strip 11 is in the middle of the tire. This ensures that the anti-skid resistance of each anti-skid strip 11 to the tire is located in the middle of the tire, ensuring the normal rotation of the tire. Then, multiple second snap-fit ​​bolts 22 pass through multiple second snap-fit ​​holes 20 on the side wall of the second adjusting strip 19 to form a snap-fit ​​fixation of the second adjusting strip 19 inside the second through hole 28.

[0023] It should be noted that when installing the fixed plate 10, anti-skid strip 11, first adjusting strip 14 and second adjusting strip 19, the fixed plate 10 should be installed first, followed by the anti-skid strip 11. Then, the second adjusting strip 19 and the first adjusting strip 14 should be adjusted synchronously according to the multiple sizes of the tire to ensure that the tread pattern on the upper surface of the anti-skid strip 11 is in the middle position of the tire, thereby ensuring that the anti-skid tire cover provides stable and uniform anti-skid performance to the tire.

[0024] Furthermore, such as Figure 2 and Figure 4 As shown, multiple sliding rods 25 are slidably arranged in a ring inside the groove 15. Each sliding rod 25 has a limiting block 26 at one end that passes through the fixed plate 10. Each limiting block 26 has a nut hole 27 on one side wall. When installing the anti-skid tire cover, the fixed plate 10 should not be fixed and centered on one side of the wheel hub, which would make it inconvenient to install and fix the multiple anti-skid strips 11 and other components later. By setting the sliding rods 25 and limiting blocks 26, pressing one end of the sliding rod 25 causes the sliding rod 25 to drive the limiting block 26 and the nut hole 27 on one side of the limiting block 26 to engage with the outside of the fixing bolt of the wheel hub, thereby fixing the fixed plate 10 on one side of the wheel hub. Example 2

[0025] Based on Example 1, further examples are made, such as... Figure 4 and Figure 6 As shown in Figures 1 and 2, each anti-slip strip 11 has multiple anti-slip rubber strips 23 on its inner wall. The multiple anti-slip rubber strips 23 increase the friction between the anti-slip strip 11 and the outer surface of the tire, preventing relative slippage between the anti-slip strip 11 and the tire during vehicle operation, which could cause slippage and stretching between the anti-slip strip 11 and the tire, leading to breakage and damage. Sound-absorbing cotton 24 is provided between every two adjacent anti-slip rubber strips 23 on the inner wall of the anti-slip strip 11. The multiple sound-absorbing cotton strips 24 absorb the noise generated by the anti-slip cover's compression and collision with ice and snow, increasing the noise reduction effect of the anti-slip tire cover and improving the user experience.
