Description

Technical Field

[0001] This application relates to the field of electric vehicles, and more specifically, to a tire and an electric vehicle. Background Technology

[0002] As the component of an electric vehicle that contacts the ground, the tire's tread pattern and tread curvature directly determine the riding experience. Currently, ordinary wet / dry tires, in pursuit of superior wet grip, often feature numerous tread grooves, resulting in low tread rigidity, reduced force transmission efficiency, and sluggish steering response. This leads to a slower leaning feel, insufficient smoothness in continuous S-curve steering, and a feeling of insecurity with insufficient shoulder support and outward swinging at large lean angles, thus negatively impacting the rider's riding experience. Utility Model Content

[0003] The purpose of this application is to provide a tire and an electric vehicle to alleviate the technical problem of existing tires affecting the riding experience in both sunny and rainy conditions.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: In a first aspect, the tire provided by this utility model includes a tire body and a groove structure provided on the tread of the tire body. The ratio of the area of ​​the groove structure to the area of ​​the tread is less than or equal to 25%; The groove structure includes a straight groove structure and two sets of pattern groove structures. The straight groove structure is located in the middle of the tread and extends circumferentially along the tread. The two sets of tread groove structures are located on both sides of the straight groove structure, and each set of tread groove structures includes a first curved groove and a second curved groove. The first curved groove and the second curved groove are arranged alternately along the circumference of the tire tread. Both the first curved groove and the second curved groove include a main groove and a branch groove that are interconnected. Both the main groove and the branch groove are arc-shaped. The length direction of the main groove is set at an angle to the straight groove structure, and the branch groove is set at an angle to the main groove.

[0005] Furthermore, the straight groove structure includes two straight grooves spaced apart along the width direction of the tread, and each straight groove extends circumferentially along the tread.

[0006] Furthermore, in the same group of patterned groove structures, the main groove of the first curved groove and the main groove of the second curved groove have the same concave direction.

[0007] Furthermore, in the first curved groove, the end of the main groove away from the straight groove is connected to the branch groove.

[0008] Furthermore, in the second curved groove, the branch groove is connected to the middle of the main groove.

[0009] Furthermore, the second curved groove includes two branch grooves, both of which are connected to the middle of the main groove and are located on both sides of the main groove. The two branch grooves have the same indentation direction.

[0010] Furthermore, the two sets of patterned groove structures are symmetrically arranged about the straight groove structure.

[0011] Furthermore, the tread includes a first tread area, a second tread area, and a third tread area along the width direction of the tread, wherein the first tread area and the third tread area are located on both sides of the second tread area; The straight groove structure is provided in the second tread area, and the two sets of the tread groove structures are respectively provided in the first tread area and the third tread area; The first tread area, the second tread area, and the third tread area all have arc-shaped cross sections along the axial direction of the tire body. The cross-sectional diameter of the first tread area is equal to the cross-sectional diameter of the third tread area and is larger than the cross-sectional diameter of the second tread area.

[0012] Furthermore, the tires are divided into front tires and rear tires; Both the front tire and the rear tire include the tire body and a groove structure provided on the tread of the tire body. The ratio of the area of ​​the groove structure of the front tire to the area of ​​the tread is set as a; The ratio of the area of ​​the groove structure of the rear tire to the area of ​​the tread is set to b, where a < b ≤ 0.25.

[0013] Secondly, the electric vehicle provided by this utility model includes wheels and tires as described in any of the above claims; The tire is mounted on the wheel.

[0014] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows: The tire provided by this utility model includes a tire body and a groove structure on the tread of the tire body; the ratio of the area of ​​the groove structure to the area of ​​the tread is less than or equal to 25%; the groove structure includes a straight groove structure and two sets of tread groove structures, the straight groove structure is located in the middle of the tread and extends along the circumference of the tread; the two sets of tread groove structures are respectively located on both sides of the straight groove structure, and each set of tread groove structures includes a first curved groove and a second curved groove, the first curved groove and the second curved groove are arranged alternately along the circumference of the tread; the first curved groove and the second curved groove both include a main groove and a branch groove that are interconnected, the main groove and the branch groove are both arc-shaped, the length direction of the main groove is set at an angle to the straight groove structure, and the branch groove is set at an angle to the main groove.

[0015] The tire's groove area to tread area ratio is less than or equal to 25%, achieving a low tread ratio design. This increases tread stiffness, resulting in smoother tipping, faster grip and steering torque transmission, and more agile steering during riding, as well as smooth continuous S-curve steering.

[0016] The straight grooves in this tire extend circumferentially along the tread, providing good guidance and facilitating stable straight-line riding. They also improve drainage and grip on wet surfaces. The first and second curved grooves, both including inclined, interconnected main and branch grooves, increase grip, enhancing traction and providing water-breaking and drainage functions on wet roads. Furthermore, the curved main grooves of both grooves extend obliquely along the width of the tread, creating an overall oblique curve that helps prevent sideslip when tilted. The combination of a central straight groove structure and the two adjacent first and second curved grooves creates a visually balanced and stable appearance.

[0017] Compared to existing tires on the market, this tire offers superior handling, providing users with a better riding experience. It is suitable for various paved roads in the city, including but not limited to cement roads, asphalt roads, cobblestone roads, and Belgian roads, and is primarily used on electric vehicles.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Example 1 As the component of an electric vehicle that contacts the ground, the tire's tread pattern and tread curvature directly determine the riding and handling experience. In current technology, ordinary day and night tires, in pursuit of wet grip, often have more tread grooves, corresponding to a higher tread-to-surface ratio (the ratio of tread groove area to total area). This leads to reduced tire tread rigidity, decreased force transmission efficiency, and sluggish steering response. The riding and handling experience is characterized by a slower leaning, insufficient smoothness in continuous S-curve steering, and a feeling of insecurity due to insufficient shoulder support and outward swinging at large lean angles, thus affecting the rider's riding experience.

[0025] In view of this, see Figure 1 and Figure 2 The tire provided in this embodiment includes a tire body 100 and a groove structure 200 on the tread of the tire body 100; the ratio of the area of ​​the groove structure 200 to the area of ​​the tread is less than or equal to 25%; the groove structure 200 includes a straight groove structure 210 and two sets of tread groove structures 220, the straight groove structure 210 is located in the middle of the tread and extends circumferentially along the tread; the two sets of tread groove structures 220 are respectively located on both sides of the straight groove structure 210, and each set of tread grooves... Structure 220 includes a first curved groove 221 and a second curved groove 222, which are arranged alternately along the circumference of the tread. Both the first curved groove 221 and the second curved groove 222 include a main groove 223 and a branch groove 224 that are interconnected. Both the main groove 223 and the branch groove 224 are arc-shaped. The length direction of the main groove 223 is set at an angle to the straight groove structure 210, and the branch groove 224 is set at an angle to the main groove 223.

[0026] The area of ​​the groove structure 200 in this tire is less than or equal to 25% of the area of ​​the tread. For example, the area of ​​the groove structure 200 to the area of ​​the tread is set to 15%, 28%, 20%, 23% or 25%, etc., to achieve a low tread stiffness design, which can increase the tread stiffness, make the tilting smooth, and the grip and steering torque transmission speed fast, resulting in flexible steering during riding and smooth continuous steering in S-curves.

[0027] The straight groove structure 210 of the tire's groove structure 200 extends circumferentially along the tread, providing good guidance and facilitating stable straight-line riding, as well as improving drainage and grip on wet surfaces. The first curved groove 221 and the second curved groove 222 in the groove structure 200, both including inclined, interconnected main grooves 223 and branch grooves 224, increase grip, enhancing riding traction and providing water-breaking and drainage functions on wet surfaces. Furthermore, because the main grooves 223 of the first curved groove 221 and the second curved groove 222 are arc-shaped and extend obliquely along the width of the tread, the first curved groove 221 and the second curved groove 222 are in a slanted curved state overall. This slanted curved tread groove structure 220 effectively prevents sideslip when tilted. Moreover, the design of the central straight groove structure 210 and the first curved grooves 221 and the second curved grooves 222 distributed on both sides gives a balanced and stable visual impression.

[0028] Compared to existing tires on the market, this tire offers superior handling, providing users with a better riding experience. It is suitable for various paved roads in the city, including but not limited to cement roads, asphalt roads, cobblestone roads, and Belgian roads, and is primarily used on electric vehicles.

[0029] The following is a detailed description of the tire's shape: In the optional solutions provided by the embodiments of this utility model, see Figure 1 and Figure 2 The straight groove structure 210 includes two straight grooves 211 spaced apart along the width direction of the tread, and each straight groove 211 extends circumferentially along the tread.

[0030] Specifically, the widths of the two straight grooves 211 are equal, and the width of the straight groove 211 is less than the distance between the two straight grooves 211.

[0031] The straight groove structure 210 includes two straight grooves 211 located in the middle of the tread, which help with straight-line stability, high guidance, and are beneficial for wetland drainage and grip.

[0032] In the optional solution provided by the present utility model embodiment, in the same group of patterned groove structures 220, the main groove 223 of the first curved groove 221 and the main groove 223 of the second curved groove 222 have the same concave direction.

[0033] Specifically, see Figure 1 and Figure 2 In the same set of groove structures 220, when the main groove 223 of the first curved groove 221 is concave upwards, the corresponding main groove 223 of the second curved groove 222 is also concave upwards. Similarly, see... Figures 5 to 8 In the same set of patterned groove structures 220, when the main groove 223 of the first curved groove 221 is recessed downwards, the corresponding main groove 223 of the second curved groove 222 is also recessed downwards.

[0034] In the same set of patterned groove structures 220, the main groove 223 of the first curved groove 221 and the main groove 223 of the second curved groove 222 have the same concave direction to avoid cross-affecting the drainage effect.

[0035] In the optional solution provided by this utility model embodiment, in the first curved groove 221, the end of the main groove 223 away from the straight groove 211 is connected to the branch groove 224.

[0036] Specifically, see Figure 3 The length of the branch groove 224 of the first curved groove 221 is less than the length of the main groove 223, and the first curved groove 221 is in the shape of a "√".

[0037] The first groove 221, shaped like a "√", enhances grip on dry and wet surfaces, improves water penetration and drainage, and prevents sideslip when tilted.

[0038] In the optional solution provided by this utility model embodiment, in the second curved groove 222, the branch groove 224 is connected to the middle part of the main groove 223.

[0039] Specifically, see Figure 6 and Figure 7 The length of the branch groove 224 of the second curved groove 222 is less than half the length of the main groove 223. When there is only one branch groove 224, the second curved groove 222 is Y-shaped overall. Furthermore, when the branch groove 224 of the first curved groove 221 extends upwards, see... Figure 6 The branch groove 224 of the second curved groove 222 may extend upward; or, see Figure 7 The branch groove 224 of the second curved groove 222 can extend downward.

[0040] The second curved groove 222, shaped like a "Y", enhances grip on dry and wet surfaces, improves water penetration and drainage, and prevents sideslip when tilted.

[0041] In the optional solutions provided by the embodiments of this utility model, see Figure 4 The second curved groove 222 includes two branch grooves 224, both of which are connected to the middle of the main groove 223 and are located on both sides of the main groove 223 respectively; the two branch grooves 224 have the same concave direction.

[0042] Specifically, when the second curved groove 222 includes two branch grooves 224, the second curved groove 222 is in an "f" shape, which can enhance the grip of the rider on dry and wet road surfaces, break water and drain water, and prevent sideslip when tilted.

[0043] In the optional solutions provided by the embodiments of this utility model, see Figure 5 The two sets of patterned groove structures 220 are symmetrically arranged about the straight groove structure 210.

[0044] Specifically, the two sets of patterned groove structures 220 are symmetrical about the straight groove structure 210.

[0045] The design of the double straight grooves 211 in the middle and the oblique curved groove structure 220 distributed symmetrically on both sides can give people a balanced and stable visual feeling.

[0046] As another implementation method, see Figures 6 to 8 The two sets of patterned groove structures are offset by 220 degrees.

[0047] Specifically, the first curved groove 221 of the pattern groove structure 220 on the left side is opposite to the second curved groove 222 of the pattern groove structure 220 on the right side. The asymmetrical arrangement of the two sets of pattern groove structures 220 can improve maneuverability.

[0048] In the optional embodiment of this utility model, the tread includes a first tread area 110, a second tread area 120, and a third tread area 130 along the width direction of the tread. The first tread area 110 and the third tread area 130 are located on both sides of the second tread area 120. A straight groove structure 210 is provided in the second tread area 120, and two sets of tread groove structures 220 are provided in the first tread area 110 and the third tread area 130, respectively. The cross-sections of the first tread area 110, the second tread area 120, and the third tread area 130 along the axial direction of the tire body are all arc-shaped. The cross-sectional diameter of the first tread area 110 is equal to the cross-sectional diameter of the third tread area 130, and is larger than the cross-sectional diameter of the second tread area 120.

[0049] Specifically, see Figure 9 The dotted lines represent the traditional tread profile, the solid lines represent the tread profile of this tire, and the circles represent the connection points of different curvature profiles. The tread profile of this tire adopts a two-segment arc design. The arc radius of the second tread area 120 in the middle is smaller than that of the traditional profile, which improves the difficulty of initial tipping. The arc radii of the first tread area 110 and the third tread area 130 on both sides are larger than that of the traditional profile, which prevents the feeling of unease caused by the acceleration of tipping in the later stage, maintains the contact area and grip, and avoids the occurrence of outward slippage.

[0050] The tire's two-section curved profile design maintains contact patch and support at large camber angles, ensuring a sense of security. Combined with different compound types, this tire can be developed to suit various usage scenarios and vehicles, offering superior handling performance compared to existing tires on the market and providing users with a better riding experience.

[0051] In the optional embodiment of this utility model, the tire is divided into a front tire and a rear tire; both the front tire and the rear tire include a tire body 100 and a groove structure 200 provided on the tread of the tire body 100; the ratio of the area of ​​the groove structure 200 of the front tire to the area of ​​the tread is set to a; the ratio of the area of ​​the groove structure 200 of the rear tire to the area of ​​the tread is set to b, where a < b ≤ 0.25.

[0052] Specifically, a is set to 0.15-0.2, b is set to 0.2-0.25, and the ratio of the front tires to the rear tires is smaller.

[0053] The front tire of the front wheel has strong tread rigidity, and the grip and steering torque transmission speed are fast. This results in flexible steering of the front wheel during riding and smooth steering in continuous S-curves. The rear wheel has sufficient grip and support bar to ensure safe riding. The front and rear wheels also have good tilting smoothness and follow-through.

[0054] Example 2 The electric vehicle provided in this embodiment of the utility model includes the tires described in Embodiment 1, and therefore also possesses all the beneficial effects described in Embodiment 1, which will not be repeated here.

[0055] In the optional embodiment of this utility model, the electric vehicle includes wheels, and tires are mounted on the wheels.

[0056] Specifically, the wheel includes a front wheel and a rear wheel, with the front wheel equipped with the front tire and the rear wheel equipped with the rear tire.

[0057] This tire features a low tread ratio design. For the front tire, the ratio of the groove structure 200 to the area is between 0.15 and 0.2; for the rear tire, the ratio is between 0.2 and 0.25. With this tread ratio design, the front tire has high tread stiffness, fast grip and steering torque transmission, resulting in agile steering and smooth turning in continuous S-curves. The rear tire has sufficient grip and support rods to ensure safe riding, and both the front and rear tires exhibit good tilting smoothness and responsiveness.

[0058] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
