Abstract
Description
Technical Field
[0001] The utility model relates to the field of rubber tires, in particular to an inflation-free rubber tire. Background Art
[0002] Tires are annular, elastic rubber products installed on various vehicles and machinery, typically made of rubber, fabric, and steel wire. Rubber tires offer excellent elasticity, wear resistance, and aging resistance, making them well suited to various complex road conditions and ensuring smooth and safe driving.
[0003] Airless tires achieve shock absorption and cushioning without the aid of air pressure. Pneumatic tires contain pressurized air enclosed in rubber. When air is compressed, the collisions of air molecules against the container walls become more intense, causing the air pressure to rise, creating a macroscopic elasticity. The superior cushioning and low rolling resistance of pneumatic tires are unmatched by any other tire to date.
[0004] Tires are circular, ground-engaging, rolling elastic rubber products installed on various vehicles or machinery. They are usually mounted on metal rims and can support the vehicle body and cushion external impacts. Application number: CN202221891607.X discloses an airless rubber tire. By turning a screw, the lower end of the screw is threadedly connected to a threaded sleeve inside the rubber tire body, thereby fixing the screw and improving the stability of the friction belt assembly. However, when the tire is in use, due to its solid rubber interior, it is not only expensive and heavy, but also has low cushioning performance and poor comfort due to its solid design.
[0005] Therefore, it is necessary to provide a kind of air-free rubber tire to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION
[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a non-inflation rubber tire provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of a front view of the tire body shown; Figure 3 for Figure 1 The structural diagram of the left side cross-sectional view of the tire body shown; Figure 4 for Figure 2 The enlarged structural diagram of area A shown in FIG. 1 shows a pneumatic-free rubber tire, comprising: a tire body 10, the outer side of the tire body 10 being a tread 101, the inner side of the tire body 10 being a tire seat 102, and a buffer assembly 2 being provided on the inner side of the tire body 1;
[0023] The buffer assembly 2 includes an array of buffer grooves 21 arranged inside the tire body 10 . Anti-deformation protrusions 22 are provided inside the buffer grooves 21 . Z-shaped shock-absorbing grooves 23 are provided inside the tire body 10 and intermittently inside the buffer grooves 21 .
[0024] By setting the buffer grooves 21 opened in the array, when the tire body 10 is impacted, the buffer grooves 21 will buffer the impact, thereby better buffering the bumps on the road and improving the user experience comfort. By setting the Z-type shock-absorbing grooves 23, when encountering a smaller impact, the tread 101 will be compressed inward, and then squeeze the Z-type shock-absorbing grooves 23 to buffer the pressure, thereby reducing the degree of vibration.
[0025] A fixing sleeve 24 is provided at the top of the inner side of the buffer groove 21, and a sliding groove 25 is provided on the inner side of the fixing sleeve 24. A support column 26 is provided on the inner side of the sliding groove 25 so as to slide up and down along the direction thereof. The bottom end of the support column 26 is fixedly connected to the bottom of the inner side of the buffer groove 21.
[0026] A buffer spring 27 is provided at the top of the inner wall of the sliding groove 25 , and the bottom end of the buffer spring 27 is fixedly connected to the top of the support column 26 . A vent hole 28 is provided on the peripheral side of the fixing sleeve 24 and through the inner side of the sliding groove 25 .
[0027] The arrangement of the buffer spring 27 and the support column 26 can provide an auxiliary buffering effect for the buffer groove 21. The arrangement of the vent holes 28 allows the fixing sleeve 24 to slide downward on the peripheral side of the support column 26 when the fixing sleeve 24 is subjected to a violent impact, and the number of vent holes 28 will gradually decrease. However, the air discharge speed of the vent holes 28 is limited, and thus the faster the fixing sleeve 24 descends, the stronger the buffering effect.
[0028] An inner cavity 29 is provided on the inner sides of the tread 101 and the tire seat 102 .
[0029] The provision of the inner cavity 29 not only reduces the rubber filling level but also improves the comfort level to a certain extent.
[0030] A grounding ring 3 is provided on the outer side of the tread 101 , and an anti-slip recess 4 is provided on the inner side of the grounding ring 3 .
[0031] The grounding ring 3 contacts the ground, thereby reducing the friction coefficient and improving the durability. The anti-slip recess 4 can provide a better anti-slip effect.
[0032] Anti-skid grooves 5 are provided on the outer side of the tread 101 and on the front and rear sides of the grounding ring 3 .
[0033] The working principle of the air-free rubber tire provided by the utility model is as follows:
[0034] Step 1: When the tire body 10 rolls and is impacted, the buffer groove 21 will buffer the impact, thereby being able to better buffer the bumps on the road and improving the user's comfort experience. Through the arrangement of the Z-shaped shock-absorbing groove 23, when encountering a smaller impact, the tread 101 will be compressed inward, thereby squeezing the Z-shaped shock-absorbing groove 23 to buffer the pressure, thereby reducing the degree of vibration. Through the arrangement of the buffer spring 27 and the support column 26, the buffer groove 21 can have an auxiliary buffering effect. Through the arrangement of the vent hole 28, when the fixing sleeve 24 is subjected to a more violent impact, the fixing sleeve 24 will slide downward on the peripheral side of the support column 26, and then the vent hole 28 will gradually decrease. The air discharge speed of the vent hole 28 is limited, so the faster the fixing sleeve 24 descends, the stronger the buffering effect.
[0035] Step 2: By setting the buffer groove 21, the inner cavity 29 and the Z-shaped shock-absorbing groove 23, the rubber usage of the tire is greatly reduced, which not only reduces the production cost but also reduces the overall weight.
[0036] Compared with the related art, the airless rubber tire provided by the present invention has the following beneficial effects:
[0037] By setting the buffer groove 21, the inner cavity 29 and the Z-shaped shock-absorbing groove 23, the rubber usage of the tire is greatly reduced, which not only reduces the production cost but also reduces the overall weight. By setting the buffer groove 21 in conjunction with the support column 26, the impact of the impact on the tread 101 on the user is effectively reduced, thereby improving comfort.
[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
