[0002] With the continuous development of the automobile industry, people have higher and higher requirements for the overall fuel economy, driving comfort, and passenger safety of vehicles. Among them, tires, as an important part of the car, have a great impact on the performance of the whole vehicle, especially the impact of their rolling resistance coefficient on fuel economy. Whether from the perspective of environmental protection or economy, reducing automobile fuel consumption is a necessary way, and it indirectly affects the emission of automobile exhaust. Reducing rolling resistance is the main way to achieve energy conservation and emission reduction.

[0031] This embodiment provides a tire. Figure 1 to Figure 2 As shown, the tire includes a tire base 1 and a tread strip 2, wherein the tread strip 2 is fixedly sleeved on the outer peripheral wall of the tire base 1, and the number of the tread strips 2 is set to be multiple, and the multiple tread strips 2 are arranged at intervals along the axial direction of the tire base 1. The tread strip 2 includes an elastic side portion 21 and a tread portion 22, two elastic side portions 21 are provided and are arranged at intervals along the axial direction of the tire base 1, and the tread portion 22 is located between the two elastic side portions 21, and the elastic side portion 21 is retractably arranged along the radial direction of the tire base 1, and the tread portion 22 is provided with a pattern, and an adjustment air cavity 201 is provided in the tread strip 2, and an air port 11 is provided on the tire base 1, and the adjustment air cavity 201 is connected with the air port 11 through an air pipe 12 provided on the tire base 1, and the air pipe 12 is provided with a control valve 121, and the control valve 121 is used to adjust the opening of the air pipe 12, and the expansion or contraction of the adjustment air cavity 201 can correspond to the extension or retraction of the elastic side portion 21.

[0032] In this embodiment, a plurality of tread strips 2 are provided on the tire base 1, and the tread strips 2 are provided in plurality and are spaced apart along the axial direction of the tire base 1. Specifically, the tread strips 2 include an elastic side portion 21 and a tread portion 22. The tread portion 22 is provided with a pattern for contacting and rubbing with the ground, and the elastic side portion 21 is retractably provided along the radial direction of the tire base 1. An adjustment air cavity 201 is provided in each tread strip 2, and an air port 11 is provided on the tire base 1. The adjustment air cavity 201 is connected to the air port 11 through an air pipe 12, and a control valve 121 is provided on the air pipe 12. The expansion or contraction of the adjustment air cavity 201 can correspond to the extension or retraction of the elastic side portion 21. The tire can adjust the air volume of the adjustment air cavity 201 corresponding to different pattern strips 2, that is, inflate or deflate the adjustment air cavity 201 through the air port 11 and the air pipe 12, so that the adjustment air cavity 201 expands or contracts, and the elastic side portion 21 is adjusted to expand and contract accordingly, so that different pattern strips 2 can be combined to extend outward and contact the ground, and the rolling resistance coefficient of the tire can be adjusted. In actual use, when the road conditions are good, the rolling resistance coefficient can be appropriately reduced in order to improve fuel economy; when the road conditions are poor, the tire grip can be appropriately increased in order to improve the stability of the whole vehicle, so as to finally achieve variable patterns to improve the comprehensive performance of the tire.

[0033] Specifically, when inflation is required, select the air pipe 12 corresponding to the tread strip 2 that needs to be inflated, open the control valve 121 on the corresponding air pipe 12, align the air port 11 with the external inflation equipment and inflate the air port 11, and let the injected gas enter the corresponding adjustment air cavity 201 through the air port 11 and the air pipe 12. As air is continuously taken into the adjustment air cavity 201, the adjustment air cavity 201 gradually expands, so that the elastic side portion 21 extends outward in the radial direction of the tire base 1, that is, the tread strip 2 expands, so that the selected tread portion 22 contacts the ground.

[0034] Specifically, when deflation is required, the air pipe 12 corresponding to the tread strip 2 that needs to be deflated is selected, and the control valve 121 on the corresponding air pipe 12 is opened, so that the gas in the adjustment air cavity 201 is discharged through the air pipe 12 and the air port 11. As the adjustment air cavity 201 is continuously exhausted, the adjustment air cavity 201 gradually shrinks, so that the elastic side portion 21 retracts inwardly along the radial direction of the tire base 1, that is, the tread strip 2 shrinks, thereby causing the tread portion 22 to break away from contact with the ground.

[0035] Specifically, Figure 2 The dotted line portion refers to the outer shape position of the tread strip 2 corresponding to the inflation of the air cavity 201 .

[0036] In this embodiment, by controlling the opening and closing of the corresponding control valve 121, the elastic side portion 21 is correspondingly adjusted to extend and retract, thereby enabling different combinations of pattern portions 22 to extend outward and contact the ground.

[0037] In this embodiment, the tread strip 2 is fixedly connected to the outer peripheral wall of the tire base 1. Optionally, the tread strip 2 and the tire base 1 can be fixed by adhesive connection or other methods.

[0038] In some other optional embodiments, the tread strip 2 is integrally formed with the tire base 1 , that is, the elastic side portion 21 , the tread portion 22 , and the tire base 1 are integrally formed.

[0039] Optionally, in this embodiment, the material of the tread strip 2 can be set to rubber.

[0040] In this embodiment, the tire base 1 has a main air cavity (not shown), and the air port 11 is connected to the main air cavity. Specifically, the air port 11 is aligned with the external inflation device and inflated, and the inflation gas can also enter the main air cavity through the air port 11, thereby inflating the tire base 1.

[0041] In this embodiment, the control valve 121 is configured as a solenoid valve.

[0042] In this embodiment, the tire base 1 is further provided with a pressure sensing element 13 for detecting the air pressure in the adjustment air cavity 201. By providing the pressure sensing element 13, the air pressure in the plurality of adjustment air cavities 201 can be obtained in real time, so that the air pressure change can be understood in real time during the inflation process of the adjustment air cavity 201, and the air pressure in the adjustment air cavity 201 is ensured to be within the required normal range to avoid excessive air pressure.

[0043] In this embodiment, the pressure sensing element 13 is configured as an air pressure sensor.

[0044] In this embodiment, two adjacent tread strips 2 and the tire base form a spacing groove 14, and the widths of the plurality of spacing grooves 14 are equal. Specifically, the provision of the spacing grooves 14 can also improve the grip of the tire and ensure the heat dissipation capability of the tire during high-speed rotation.

[0045] In this embodiment, the air tube 12 is fixedly buried in the tire base 1. Specifically, the tire base 1 is processed to form a through hole during the manufacturing process, and the air tube 12 is located in the through hole. Both ends of the air tube 12 extend out of the through hole, one end of which is connected to the air port 11, and the other end extends into the adjustment air cavity 201.

[0046] In this embodiment, the distance between the two elastic side portions 21 of the plurality of pattern strips 2 is sequentially increased or decreased. Specifically, for each pattern strip 2 , the distance between its two elastic side portions 21 is the width of the pattern strip 2 .

[0047] Specifically in this embodiment, the number of the tread strips 2 is set to 5, and in the axial direction of the tire base 1, the spacing between the two elastic side portions 21 of the five tread strips 2 is set to 30 mm, 60 mm, 90 mm, 120 mm and 150 mm, respectively. That is, the widths of the five tread strips 2 are 30 mm, 60 mm, 90 mm, 120 mm and 150 mm, respectively.

[0048] For example, Figure 2 The five tread strips 2 from left to right are numbered 1, 2, 3, 4 and 5, and the widths of the tread strips 2 corresponding to 1, 2, 3, 4 and 5 are 150mm, 120mm, 90mm, 60mm and 30mm, respectively. Taking the tire width of 300mm required by the tire load as an example, the combination of the above five tread strips 2 can be 2+3+6, 2+4+5+6, and 3+4+5+6, so as to realize three tires with different performance parameters. In addition, the five tread strips 2 can also be combined in other different ways according to different tire loads and road conditions, which will not be limited too much here.

[0049] In this embodiment, the shape of the pattern on the pattern portion 22 can be set accordingly according to actual design requirements to achieve the purpose of reducing tire deformation and resistance, improving grip and heat dissipation capabilities, and no excessive restrictions are made here.

[0050] In summary, the tire provided in this embodiment can adjust the combination of tread strips 2 that best suits the road conditions according to different road conditions, and realize whether the tread strips 2 are in contact with the ground by means of inflation and deflation, and finally realize variable treads to improve the comprehensive performance of the tire. That is, when the road conditions are good, the rolling resistance coefficient is reduced and the fuel economy is improved; when the road conditions are poor, the tire grip is improved and the stability of the whole vehicle is improved.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
