Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle tire technology, specifically a snow tire with tread warning markings. Background Technology
[0002] Currently, my country's national standards have clear regulations on the tread wear limits of radial tires for passenger cars, requiring wear indicators to be set on the longitudinal grooves of the tire crown. When the tread wears down to 1.6mm, the driver is reminded to replace the tire. For radial tires for snow, in addition to the general tread wear limit requirements, a special snow wear indicator is specified as half the depth of the main tread groove. When this limit is reached, the driver is reminded that the tire has lost its snow performance and needs to be replaced.
[0003] However, traditional snow wear indicators have significant shortcomings. They can only indicate when a tire has reached its limit of wear. As tire grooves decrease during use, they cannot accurately represent the tire's traction on snowy roads. The lack of warning signs about the gradual loss of snow performance makes it difficult for drivers to know in advance about changes in tire performance on snow, thus affecting driving safety.
[0004] Based on this, a snow tire with tread warning markings is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0005] The purpose of this invention is to provide a snow tire with tread warning markings to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A snow tire with tread warning markings includes a tread and two sidewalls formed around the tread on both sides. Warning markings are provided in the area of the tread, and the warning markings are composed of snowflake patterns and the letters SNOW. A wear warning mechanism is provided inside the tread at the location of the warning markings.
[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0009] In one alternative embodiment: the wear alarm mechanism includes a mounting box located inside the tire tread at the warning sign. A resistance sensor is fixedly connected in the mounting box. The resistance sensor is connected to a resistor block, the outer end of which is wrapped with a rubber sleeve. The resistor block is located at the deepest point in the middle of the warning sign. The mounting box contains a battery and a wireless transmission module. The resistance sensor is electrically connected to both the battery and the wireless transmission module.
[0010] In one alternative: the warning sign is designed to be evenly distributed in N equal parts along the tire circumference, where N≥4, and the distance from the edge of the tread block is >2mm.
[0011] In one alternative: the warning sign includes at least 6 depth characteristics, with a characteristic range of 0 to 1 / 2H+1, where H is the pattern depth.
[0012] In one alternative: the warning sign is coated with fluorescent paint.
[0013] In one alternative: the pattern size L is 8-14 mm; M is 4-7 mm; and N is 7-12 mm.
[0014] In one alternative: the sidewall of the warning sign is perpendicular to the circumferential surface of the tire.
[0015] In one alternative: the warning markings may be distributed at the center of the tire tread and on the shoulder.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention arranges graphics and text of varying depths on the tire crown. As the tire is used, the corresponding graphics and text will disappear, thus representing the tire's performance loss in snowy conditions. Furthermore, the addition of a wear warning mechanism can promptly inform the driver when the tire reaches its wear limit, reminding the driver to replace the tire. Attached Figure Description

[0024] 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.
[0025] In one embodiment, such as Figures 1-5 As shown, a snow tire with tread warning markings includes a tread 3 and two sidewalls 2 forming around the tread 3. A warning marking 1 is provided in the area of the tread 3. The warning marking 1 consists of a snowflake pattern and the letters SNOW. A wear warning mechanism is provided inside the tread 3 at the location of the warning marking 1. By setting the warning marking 1, the corresponding text and graphics will disappear as the tire is used, thus indicating the performance loss of the tire in icy and snowy conditions. The wear warning mechanism can promptly inform the driver that the tire has reached its wear limit and remind the driver to replace the tire.
[0026] In this embodiment, as Figure 5 As shown, the wear warning mechanism includes a mounting box 401 located inside the tire tread 3 at the warning sign 1. A resistance sensor 402 is fixedly connected in the mounting box 401. The resistance sensor 402 is connected to a resistor block 403, the outer end of which is covered with a rubber sleeve. The resistor block 403 is located at the deepest point in the middle of the warning sign 1. The mounting box 401 contains a battery 404 and a wireless transmission module 405. The resistance sensor 402 is electrically connected to both the battery 404 and the wireless transmission module 405. The warning sign 1 has multiple different depths set with a snowflake pattern. When the wear reaches the deepest point, it will wear down the resistor block 403, causing a change in the resistance of the resistor block 403. After detecting the change in the resistance of the resistor block 403, the resistance sensor 402 transmits the situation to the driver through the wireless transmission module 405, issuing a reminder.
[0027] In one embodiment, such as Figure 1 As shown, the warning markings 1 are evenly distributed in N equal parts along the tire circumference, where N≥4, and the distance from the edge of the tread block is >2mm. When N≥4, the warning markings can be distributed relatively evenly and meticulously along the tire circumference, allowing for more accurate monitoring of wear conditions in different parts of the tire. The distance of the warning markings from the edge of the tread block is >2mm, which avoids affecting the integrity and function of the tread block. If the markings are too close to the tread block, they may damage the structure of the tread block, affecting the tire's water drainage effect on wet roads, reducing tire grip, and thus affecting vehicle driving safety and handling performance. Maintaining an appropriate distance ensures that the tread block functions properly and maintains the tire's various performance indicators.
[0028] In one embodiment, such as Figure 2 and Figure 3As shown, the warning sign 1 contains at least 6 depth characteristics, with a characteristic range of 0 to 1 / 2H+1, where H is the tread depth. By setting multiple different depths, it is to ensure that the tire snow performance warning sign 1 achieves its warning function and to concretely quantify the correspondence between snow performance loss and the sign.
[0029] In one embodiment, such as Figure 1 As shown, the warning sign 1 is coated with fluorescent paint. When driving at night or in low-light environments, the fluorescent paint can absorb and store the light in the surrounding environment and then emit fluorescence in the dark, making the warning sign clearly visible. This helps the driver to quickly and accurately detect the wear condition of the tires when checking them, even in the absence of sufficient lighting, and to know in time whether the tires need to be replaced.
[0030] In one embodiment, such as Figure 4 As shown, the pattern size L is 8-14mm; M is 4-7mm; N is 7-12mm. The size of the pattern can be designed specifically according to the diameter of different tires.
[0031] In one embodiment, such as Figure 1 As shown, the sidewall of the warning sign 1 is perpendicular to the circumferential surface of the tire, and the side of the warning sign 1 is perpendicular to the circumferential surface of the tire. This can effectively and intuitively express the wear of the tire tread 3 on the ground at the warning sign 1.
[0032] In one embodiment, such as Figure 1 As shown, the warning labels 1 are distributed at the center of the tire tread and on the shoulder. When the tire is in motion, the center of the tread has the largest contact area with the ground and is subjected to uniform force, making it the part that wears most directly and obviously. Placing warning labels at the center of the tread can visually reflect the overall wear condition of the tire. When the vehicle turns, accelerates, or brakes, the tire shoulder bears greater lateral forces and pressures, making it prone to uneven wear. Placing warning labels on the tire shoulder allows for specific monitoring of the wear condition of the tire shoulder.
[0033] The above embodiment discloses a snow tire with tread warning markings. The warning markings 1 are set with snowflake patterns at multiple different depths. Different patterns will appear when the wear level is different, making it convenient for the driver to observe the degree of tire wear. The warning markings 1 are sprayed with fluorescent paint, which helps the driver to quickly and accurately detect the tire wear condition when inspecting the tires, even in the absence of sufficient lighting, and to know in time whether the tire needs to be replaced. When the wear reaches the deepest point, it will wear down the resistor block 403, causing the resistance of the resistor block 403 to change. After the resistance sensor 402 detects the change in the resistance of the resistor block 403, it transmits the situation to the driver through the wireless transmission module 405 to issue a reminder.
[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
