Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

A tire 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 6. The tire 100 may be applied to a vehicle such as an electric vehicle (not shown), an electric scooter (not shown). In the following description of the present application, the tire 100 is explained as an example of application to an electric vehicle. Of course, those skilled in the art will appreciate that the tire 100 may also be applied to other types of vehicles, not limited to electric vehicles and electric scooters.

As shown in fig. 1 to 6, a tire 100 according to an embodiment of the first aspect of the present invention includes a first wheel bead 1, a second wheel bead 2, and a plurality of damping columns 3. In the description of the present invention, "a plurality" means two or more.

Specifically, the second wheel bead 2 is provided radially outward of the first wheel bead 1. Here, it should be noted that the direction "outer" is understood to be a direction away from the center of the first wheel bead 1, and the opposite direction is defined as "inner", i.e. a direction toward the center of the first wheel bead 1. A plurality of damping columns 3 are connected between the first wheel tire bead 1 and the second wheel tire bead 2, the plurality of damping columns 3 are arranged at intervals along the circumferential direction of the first wheel tire bead 1 and the second wheel tire bead 2, and each damping column 3 is of a columnar structure.

For example, in the example of fig. 1-2 and 5, each of the first and

second wheel beads

1, 2 is an annular structure, the radial dimension of the second wheel bead 2 is greater than the radial dimension of the first wheel bead 1, a plurality of damping columns 3 are connected between the first and

second wheel beads

1, 2 at intervals, specifically, an inner end of each damping column 3 is connected to the outer circumferential surface of the first wheel bead 1, an outer end of each damping column 3 is connected to the inner circumferential surface of the second wheel bead 2, and the central axis of each damping column 3 may be parallel to the central axis of the tire 100. With such an arrangement, the tire 100 does not need to be inflated, and compared with a conventional pneumatic tire, the situation that severe abrasion or irregular abrasion or even tire burst is generated on the tread of the tire 100 due to the fact that the bearing capacity of the tire 100 is weakened due to the fact that the pneumatic tire is punctured and air leakage occurs does not exist, and when the tire 100 is applied to a vehicle such as an electric vehicle, the driving safety can be effectively guaranteed. Moreover, by providing the vibration damping columns 3 in a columnar structure and spacing the plurality of vibration damping columns 3 from each other, the vibration damping effect is good, so that a vehicle such as an electric vehicle can have good riding comfort, and the support and bearing capacity of the tire 100 can be improved.

According to the utility model discloses tire 100 makes a plurality of damping post 3 connect between first round of tire bead 1 and second round of tire bead 2 along circumference spaced apart through the setting to make every damping post 3 be columnar structure, when guaranteeing the damping effect, improved tire 100's support nature and bearing capacity. Moreover, the tire 100 does not need to be inflated, and running safety can be effectively ensured when the tire 100 is applied to a vehicle such as an electric vehicle.

According to some embodiments of the present invention, referring to fig. 2, an included angle between centers of two adjacent damping pillars 3 and a center connecting line of the tire 100 is α, wherein α satisfies 5 ° ≦ α ≦ 10 °, therefore, by setting an included angle α between centers of two adjacent damping pillars 3 and a center connecting line of the tire 100 to satisfy 5 ° ≦ α ≦ 10 °, it is possible to further ensure good damping effect and further improve the support and bearing capacity of the tire 100, for example, when the included angle α is less than 5 °, the distance between two adjacent damping pillars 3 is relatively short, the gap is small, the damping effect is relatively poor, and thus the riding comfort of the vehicle such as an electric vehicle is affected, and when the included angle α is greater than 10 °, the distance between two adjacent damping pillars 3 is large, which results in small support and bearing capacity of the entire tire 100, and thus the load of the vehicle such as an electric vehicle cannot be well supported.

Alternatively, a plurality of damping columns 3 are evenly spaced along the circumferential direction of the first and

second wheel beads

1, 2, as shown in fig. 1 and 2. A plurality of shock absorbing columns 3 may be distributed in an array about the center of the tire 100. Thus, the force applied throughout the tire 100 may be more uniform.

Further, the number of the damper columns 3 is a multiple of 4. When a plurality of damping posts 3 were evenly arranged, can guarantee that it can drop on the same diameter direction of tire 100 two by two, the support nature is better, and the travelling comfort is better.

Optionally, the number of damping columns 3 is greater than 16. In fig. 2, 48 damping columns 3 are shown for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to other numbers of damping columns 3, which also falls within the protection scope of the present invention.

Wherein the first wheel bead 1 and the second wheel bead 2 are coaxially arranged, and a longitudinal section of each damping cylinder 3 passes through the central axis of the first wheel bead 1. The longitudinal section of each damping cylinder 3 now also passes through the central axis of the second wheel bead 2. The center of the tire 100 is where the center axes of the first and

second tire beads

1, 2 are located. With this arrangement, when the tire 100 is loaded, it is possible to effectively ensure that the acting force acts at the center of the tire 100.

According to some embodiments of the present invention, as shown in fig. 2, the inner end of each damping cylinder 3 is in surface contact with the first wheel bead 1, and the outer end of each damping cylinder 3 is in surface contact with the second wheel bead 2. Thus, the contact area between each damping post 3 and the first and

second tire beads

1 and 2 is large, so that the strength of the entire tire 100 can be improved, and the service life of the tire 100 can be prolonged.

Optionally, the cross section of each damping column 3 can be circular, so that the rebound resilience is good, and the damping effect is good. Of course, the utility model discloses be not limited to this, every damping post 3's cross sectional shape still can be for oval, and the damping is effectual, and intensity is high. Alternatively, the cross-sectional shape of each vibration damping post 3 may be semicircular, semi-elliptical, hexagonal, trapezoidal, triangular, or the like. It will be appreciated that the specific shape of the damping cylinder 3 may be specifically configured according to practical requirements to better meet practical applications.

Optionally, the first wheel bead 1, the second wheel bead 2 and the plurality of damping columns 3 are a unitary injection molded part. At this time, the first wheel bead 1, the second wheel bead 2 and the plurality of damper columns 3 are integrally injection-molded. For example, the tire 100 may be injection molded once by a tire mold and then vulcanized, in which case the tire 100 has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents.

Further, a plurality of grooves 21 may be formed on the outer circumferential surface of the second tire bead 2 to improve the braking friction of the tire 100.

According to a second aspect of the present invention, a vehicle, such as an electric vehicle, comprises a tire 100 according to the above first aspect of the present invention.

According to the utility model discloses vehicle such as electric motor car through adopting foretell tire 100, need not to inflate, and the damping is effectual, and support nature and bearing capacity are high, and the durability is good, has greatly made things convenient for the user, and has guaranteed driving safety and the travelling comfort of taking.
