Example 1

The vehicle wheel usually comprises a tire and a rim for supporting the tire, and a cavity formed by the tire and the rim is filled with air so as to ensure that the tire pressure is normal and the vehicle can normally run. When the tire leaks, if the tire is punctured by a sharp object, the tire pressure is reduced, and the tire needs to be repaired in time in order to ensure the driving safety. When the automobile is in the long way, the automobile cannot find a repair shop to repair the tire in time, and a driver needs to replace the spare tire by self operation, so that the automobile is strenuous and is difficult to operate.

The utility model provides a leak-proof and air-retaining automobile wheel, as shown in fig. 1 and 2, comprising a wheel body 100, wherein the wheel body 100 comprises:

a tire 10 for supporting an automobile body;

a rim 20 for supporting the tire 10; the tire 10 is mounted on the outer peripheral side of the rim 20; the tire 10 and the rim 20 are clamped together to form an air cavity 30 for storing air;

a plurality of clamping pieces 21 are arranged on one side of the rim 20 facing the tire 10; at least one air bag 40 is clamped outside the clamping piece 21, and the air bag 40 is positioned in the air cavity 30; when the tire 10 is broken and deflated, the air bag 40 supports the tire 10.

Specifically, an air bag 40 is provided in an air chamber 30 formed by the tire 10 and the rim 20, the air bag 40 is inflated to make the air bag 40 in an inflated state, and the air chamber 30 is inflated to ensure the supporting force of the tire 10. When the tire 10 leaks air and all the air bags 40 are not damaged, the air in the space between the air cavity 30 and the air bags 40 slowly escapes out of the tire 10 along with the prolonging of time, the air pressure of the tire 10 is slightly reduced, and on one hand, the air leakage speed of the tire 10 is delayed because part of the air is stored in the air bags 40; on the other hand, due to the supporting function of the air bags 40 on the tire 10, the wheel body 100 can still work normally, so that the service life of the tire 10 in a deflated state is prolonged, enough time is provided for a user to find a repair shop along the way, and the user does not need to change the spare tire by himself. When the tire 10 is punctured by a sharp object, the air bag 40 is punctured, so that the air bag 40 is also damaged and starts to leak, and at the time, the air escaping from the tire 10 comprises two conditions, namely, the air in the space between the air cavity 30 and the air bag 40 slowly escapes from the tire 10, and the air in the air bag 40 slowly leaks into the space between the air cavity 30 and the air bag 40 and then slowly escapes from the tire 10. The arrangement of the air bags 40 can delay the air leakage speed of the tire 10 under two air leakage conditions, and can support the tire 10 by the rest of the air bags 40 to prevent the tire from being flat, thereby prolonging the safe driving time of the tire 10 in the air leakage state. In addition, the clamping piece 21 is arranged on the rim 20, so that the air bag 40 is convenient to assemble and fix, and the installation stability of the air bag 40 is improved.

In one embodiment, as shown in fig. 4, the air bag 40 includes a first bag 41, and the first bag 41 has a cylindrical shape. The first bag 41 has a slot for engaging with the engaging member 21. Due to the arrangement of the clamping piece 21, the design of the first bag body 41 with different sizes can be matched by adjusting the space between the clamping piece 21 and the rim 20. When the space between the clips 21 and the rim 20 is designed to be large, the space between the adjacent clips 21 is designed to be enlarged to accommodate the first bag body 41 of a large size, and at this time, the first bag body 41 is designed to be large enough to support the inner surface of the tire 10.

In yet another embodiment, when the space between the clip 21 and the rim 20 is designed to be small, the size of the first pocket 41 matched with the clip 21 is small, and the first pocket 41 cannot be supported to the inner surface of the tire 10. As shown in fig. 1 and 3, the air bag 40 includes at least two connected bag bodies, one bag body is provided with a slot for being sleeved on the peripheral side of the clamping member 21, and the other bag bodies are used for filling the air cavity 30. Specifically, the air bag 40 includes a first bag 41 and a second bag 42. The first bag 41 is sleeved on the fastener 21, the second bag 42 is connected to the first bag 41, the second bag 42 is larger than the first bag 41 in size and is used for filling the air cavity 30, and when the outer surface of the tire 10 is squeezed, the second bag 42 is supported on the inner surface of the tire 10.

Further, the air bag 40 is an integrated structure, which is convenient for processing and installation.

Further, in one embodiment, the different pockets of the air bag 40 are connected to each other to save the processing material of the air bag 40. In another embodiment, the different pockets of the air bag 40 are not connected and are of a separate pocket structure. When the tire 10 is punctured, the sharp object usually penetrates into the tire 10 from the outer surface of the tire 10 toward the air cavity 30, the bag body close to the tire 10 is punctured and leaks air, and the rest bag body of the air bag 40 is intact and kept in an expanded state, so as to prevent the air bag 40 from completely leaking air at the position and reduce the degree of deflation of the tire 10 corresponding to the position to a certain extent.

In one embodiment, the clip 21 is fixed to the rim 20 by a fastener to facilitate the assembly and disassembly of the clip 21. When the air bag 40 is assembled, the air bag 40 is sleeved on the outer periphery of the clamping piece 21, and then the clamping piece 21 is installed on the rim 20, so that the air bag 40 can be conveniently assembled and disassembled.

Further, as shown in fig. 2, a connecting portion 22 is protruded from a side of the rim 20 facing the tire 10 for fixing the snap-in member 21. The clamping piece 21 is fixed through the protruding connecting portion 22, the assembling structure is simple, and the clamping piece 21 is prevented from being arranged to influence the assembling of the rim 20 and the tire 10. The connecting portion 22 is provided with a mounting hole, and the mounting of the clamping member 21 is realized through a fastener.

Further, as shown in fig. 2 and 4, one end of the clamping member 21 away from the connecting portion 22 is bent to form a stopping portion 211, so as to press the air bag 40 against the connecting portion 22. Specifically, the clamping member 21 includes an optical axis 212 and a stopping portion 211, the end of the air bag 40 away from the stopping portion 211 from the optical axis 212 is sleeved on the optical axis 212, and the stopping portion 211 is used for supporting one end of the air bag 40 away from the connecting portion 22, so that the air bag 40 is fixed by the friction between the inner surface of the clamping groove of the air bag 40 and the outer surface of the optical axis 212, and the connecting portion 22 and the stopping portion 211 at the two ends of the air bag limit the movement of the air bag 40 along the extending direction of the clamping member 21, thereby stabilizing the installation of the air bag 40.

In one embodiment, the plurality of air pockets 40 are arranged in an annular array. Specifically, the outer contour of the rim 20 is generally circular, and a plurality of air bags 40 are designed to be arranged in an annular array, so that the aesthetic degree of the rim 20 after the air bags 40 are assembled is improved, the design and the installation of the air bags 40 are convenient, and the supporting function of the air bags 40 on each part of the tire 10 is uniform.

In one embodiment, two adjacent air bags 40 are abutted, so that all the air bags 40 in the air cavity 30 form an integral supporting structure, and the supporting strength of all the air bags 40 on the tire 10 is improved.

Furthermore, the air bags 40 are of an integral structure, and when the air bags are assembled, the air bags 40 are sleeved on the corresponding clamping pieces 21 together as a whole, so that the assembling processes of the air bags 40 are reduced.

In one embodiment, the material of the air bag 40 is preferably low density polyethylene, which is waterproof, moisture-proof, non-toxic and has good barrier properties.

In one embodiment, the airbag 40 is an inflatable airbag 40, and the airbag 40 can be inflated periodically to ensure the inflation degree of the airbag 40. In another embodiment, the airbag 40 is a non-inflatable airbag 40, and the replacement of the airbag 40 is performed periodically, which is relatively expensive.

In one embodiment, the air bag 40 is a gas column bag, which has good cushioning and supporting properties.

In one embodiment, the number of the air bags 40 clamped outside the clamping member 21 is at least two. The first and second air bags are engaged by an engaging member 21. The first air bag and the second air bag have the same structure and size, and are sleeved on the same connecting piece 21. When the tire 10 is damaged and the first air bag or the second air bag on the clamping piece 21 is damaged and deflated, the other air bag can still support the corresponding part of the tire 10, so that the service life of the wheel body 100 is prolonged, enough time is provided for a user to find a repair shop along the way, and the user does not need to change the spare tire by himself.

Example 2

The utility model provides an automobile which comprises the leak-proof air-retaining automobile wheel. In order to ensure the driving safety, the leakage-proof and gas-retaining automobile wheel is applied to all four wheels. The wheel body 100 reduces the speed of the tire 10 when leaking air, reduces the speed of the tire 10 when collapsing, improves the driving safety, provides enough time for users to find a repair shop along the way, and the users do not need to replace spare tires with great effort by themselves by arranging the air bag 40 in the air cavity 30.
