Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of bicycles, in particular to a solid tire and a solid wheel set. BACKGROUND

[0002] The electric bicycle usually adopts a solid inner tire. The solid inner tire has a heavy weight, poor shock absorption, and poor heat dissipation performance in general. After running for a period of time, the heat dissipation effect is poor, which easily leads to burning of the wheel set, and the burning of the wheel set leads to the scrapping of the entire wheel set. The burning of the wheel set refers to the phenomenon that the inner tire of the electric bicycle collapses or the chemical properties change due to high temperature.

[0003] In the related art, the inner tire is made into a foamed type. The foamed type inner tire has a large number of small holes inside, which reduces the weight to a certain extent, but the heat is still accumulated in the small holes. The foamed type inner tire is generally made of rubber or rubber-like products, such as polyurethane. The heat conduction performance of the material itself is poor, and the heat is difficult to be conducted out. The problem of heat generation and burning of the wheel set of the electric bicycle has not been fundamentally solved. CONTENT OF THE INVENTION

[0038] In the description of the present disclosure, it should be noted that the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the devices referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present disclosure.

[0039] In the description of the utility model, it is explained that, unless otherwise specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0040] Figure 1 The appearance structure schematic diagram of the solid tire provided by the embodiment of the present disclosure is shown. Figure 5 The explosion view of the solid tire provided by the embodiment of the present disclosure is shown. The solid tire 100 provided by the embodiment of the present disclosure comprises: an annular tire body 1, the surface of the annular tire body 1 is provided with a plurality of first flow guide grooves 13, each first flow guide groove 13 is sequentially and spacedly arranged along the circumference of the annular tire body 1, the first flow guide groove 13 extends from the outer side ring surface 11 of the annular tire body 1 to the inner side ring surface 12 of the annular tire body 1, so that the hot air can flow and dissipate heat from the contact position of the inner tire and the outer tire 300 to the contact position of the inner tire and the hub 200 along the first flow guide groove 13. For example, in summer, the road surface temperature is relatively high, and a large amount of heat will be transferred from the ground to the solid tire 100 during riding. By arranging the first flow guide groove 13 on the solid tire 100, the heat can be guided from one side of the outer tire 300 to one side of the metal hub 200. The metal hub 200 rotates continuously, which has a similar effect of air cooling, and can achieve the effect of rapid heat dissipation.

[0041] In some possible embodiments, the first flow guide groove 13 can be a closed annular groove, so as to form a complete circulating air path, which is beneficial to the circulation of air in the annular groove and increases the air flow. During the circulation of hot air along the annular first flow guide groove 13, the hot air will fully contact the metal hub 200 located at the inner side ring surface 12 of the annular tire body 1, and the hot air and the metal hub 200 exchange heat, so that a large amount of heat is finally dissipated from one side of the metal hub 200.

[0042] Figure 2 The side view of the solid tire provided by the embodiment of the present disclosure is shown. In combination with Figure 1 and Figure 2As shown, the solid tire 100 includes a plurality of protrusions 2, each protrusion 2 is located in a corresponding first flow guide groove 13, and the protrusion 2 protrudes from the outer surface of the annular tire body 1. In the state that the outer tire 300 is sleeved on the inner tire, the protrusion 2 can abut against the inner surface of the outer tire 300, that is, the interference fit between the inner tire and the outer tire 300 is achieved. During riding, the outer tire 300 deforms when contacting the ground, so that the protrusion 2 is compressed by an external force, thereby reducing the space of the local position of the first flow guide groove 13 and compressing the air in the local space of the first flow guide groove 13, thereby forming a flowing air flow in the first flow guide groove 13. Because the solid tire 100 is always in a rotating state, and each protrusion 2 is compressed in turn, thereby forming a continuously circulating air flow in the first flow guide groove 13, which is beneficial to accelerate the heat dissipation.

[0043] It should be noted that each protrusion 2 can be arranged on the outer side ring surface 11 of the annular tire body 1, which is the outermost side of the solid tire 100, that is, the largest diameter. During riding, the protrusion 2 will be effectively extruded and compressed. Each protrusion 2 is arranged in turn along the circumference of the solid inner tire, and each protrusion 2 can be compressed in turn during riding.

[0044] In some possible embodiments, as shown in Figure 2 As shown, the outer side ring surface 11 of the annular tire body 1 is provided with a second flow guide groove 3, the second flow guide groove 3 extends along the circumference of the annular tire body 1, and the second flow guide groove 3 communicates each first flow guide groove 13.

[0045] The second flow guide groove 3 is an annular closed groove, the second flow guide groove 3 extends through each first flow guide groove 13 in turn, and the second flow guide groove 3 communicates each first flow guide groove 13. The second flow guide groove 3 forms a circulating air flow channel at the lateral edge of the solid tire 100, which is beneficial to the flow of hot air in the second flow guide groove 3 and ultimately into the metal hub inside the solid tire 100 through each first flow guide groove 13. The arrangement of the second flow guide groove 3 is beneficial to increase the air flow between the solid tire 100 and the outer tire 300, guide the hot air into each first flow guide groove, thereby improving the heat dissipation efficiency.

[0046] Among them, the second flow guide groove 3 forms an intersection area with each first flow guide groove 13, and each protrusion 2 is located in a corresponding intersection area, and an air flow can be formed in the first flow guide groove 13 and the second flow guide groove 3 when the protrusion 2 is compressed.

[0047] In some possible embodiments, the width of the second flow guide groove 3 is not less than 3mm, and the groove depth of the second flow guide groove 3 is not less than 3mm.

[0048] If the width of the second flow guide groove 3 is too small, the air flow is small, which is not conducive to rapid heat dissipation. Similarly, if the depth of the second flow guide groove 3 is too shallow, the space compression in the second flow guide groove 3 is not large during riding, and the air flow is insufficient. A large number of experiments have verified that when the width of the second flow guide groove 3 is not less than 3 mm and the depth of the second flow guide groove 3 is not less than 3 mm, the space compression in the second flow guide groove 3 is moderate during riding, a strong air flow can be formed, the air flow is large, and the heat dissipation effect is good.

[0049] In some possible embodiments, as shown in Figure 5 The solid tire 100 includes a heat conduction member 4 embedded in the first flow guide groove 13 and the second flow guide groove 3. The arrangement of the heat conduction member 4 is conducive to the conduction of the high-temperature heat on one side of the outer annular surface 11 of the solid tire 100 to the metal hub on the other side of the inner annular surface 12 of the solid tire 100, further improving the heat dissipation efficiency.

[0050] The heat conduction member 4 is shaped to match the shape of the first flow guide groove 13 and the second flow guide groove 3, and includes a heat conduction ring piece 41 and a plurality of heat conduction arc pieces 42. Each heat conduction arc piece 42 is arranged in sequence and at intervals along the circumference of the heat conduction ring piece 41. The heat conduction ring piece 41 is embedded in the second flow guide groove 3, and each heat conduction arc piece 42 is embedded in a corresponding first flow guide groove 13. Each heat conduction arc piece 42 extends from the heat conduction ring piece 41 to the inner annular surface 12 of the annular tire body 1. Thus, the heat on the outer side of the solid tire 100 can be effectively transferred to the inner side of the tire to be close to or contact the metal hub, accelerating the transfer of heat and improving the heat dissipation efficiency. The heat conduction member 4 can be a metal film or a composite material film with good heat conduction.

[0051] Figure 4 A cross-sectional view of the solid tire provided by the embodiments of the present disclosure is shown. In combination with Figure 1 and Figure 4 As shown, a plurality of radial holes 5 are arranged on the inner annular surface 12 of the annular tire body 1. Each radial hole 5 is arranged in sequence and at intervals along the circumference of the annular tire body 1, and each radial hole 5 extends to the outer annular surface 11 of the annular tire body 1.

[0052] The inner annular surface 12 of the annular tire body 1 is the side of the solid tire 100 that contacts the metal hub 200. The arrangement of the plurality of radial holes 5 on the inner annular surface 12 is conducive to the conduction of the heat on the inner side of the solid tire 100 to the metal hub 200, which can dissipate heat by means of the metal hub 200. The radial holes 5 also have the effect of reducing weight. The diameter of the radial hole 5 is greater than 3 mm, the distance between adjacent radial holes 5 is not less than 3 mm, and the depth of the radial hole 5 is not less than 3 mm.

[0053] In combination with Figure 1 and Figure 4As shown, a plurality of axial holes 6 are arranged on the annular carcass 1, each axial hole 6 is arranged in sequence and spaced along the circumference of the annular carcass 1, the axial hole 6 is parallel to the central axis of the annular carcass 1, and the axial hole 6 penetrates the annular carcass 1.

[0054] A plurality of axial holes 6 are arranged on the solid tire 100, which is beneficial to lead out the heat inside the solid tire 100, and also has the effect of weight reduction, the diameter of the axial hole 6 is greater than 3mm. And the minimum distance between two axial holes 6 is not less than 3mm.

[0055] Figure 6 The structure schematic diagram of the solid wheel set provided by the embodiment of the present disclosure is shown. In combination with the above description of the solid tire 100, the structure of the solid wheel set is described. Figure 5 And Figure 6 As shown, the embodiment of the present disclosure also provides a solid wheel set, which comprises a hub 200, an outer tire 300 and the above-mentioned solid tire 100, the solid tire 100 is sleeved on the hub 200, and the outer tire 300 is sleeved on the solid tire 100. The outer side annular surface 11 of the solid tire 100 is close to or contacts the outer tire 300. The inner side annular surface 12 of the solid tire 100 is close to or contacts the metal hub 200. The first flow guide groove 13 of the annular carcass 1 extends from one side of the outer tire 300 to one side of the metal hub 200. During riding, a large amount of heat will be transmitted from the ground to the outer tire 300 and the solid tire 100, and by arranging the first flow guide groove 13 on the solid tire 100, the heat can be guided from one side of the outer tire 300 to one side of the metal hub 200. The metal hub 200 rotates continuously, has a similar wind cooling effect, and can achieve the effect of rapid heat dissipation.

[0056] The above description has been given for the purpose of illustration and description. Furthermore, this description is not intended to limit the embodiments of the present disclosure to the forms disclosed herein.
