Description

Explosion-proof tyre

Technical Field

The utility model relates to the field of tires, in particular to an anti-prick and anti-explosion tire, and specifically relates to an anti-explosion tire.

Background

The tires used in the existing vehicles are about 90% vacuum tires and 10% tires in the form of a conventional combination of inner and outer tires. The vacuum tire has the advantages of high pressure resistance, good tightness, convenient installation and the like, is widely applied, and has the most outstanding advantages that after the vacuum tire is abnormally punctured by foreign matters, the vacuum tire can firmly wrap the foreign matters due to the thick tire wall, so that high-pressure air in the tire cannot escape instantaneously, and serious traffic accidents caused by instantaneous pressure loss of the tire are avoided.

In the prior art, in order to avoid accidents such as vehicle rollover and the like caused by vehicle balance breaking due to instant pressure loss of tires, a run-flat tire is designed, is commonly called as a run-flat tire and is generally applied to high-grade luxury cars. The principle is that on the basis of the existing vacuum tire, the tire side wall is thickened, and the tire is punctured by foreign matters to cause instant pressure loss of the tire, and because the thickness of the tire side wall is large, the automobile can still be supported to run for about 100km at the speed of not higher than 80km/h depending on the rubber with larger thickness of the tire, so that the automobile can safely run to a nearby maintenance point under the state of zero tire pressure after the automobile tire is punctured. Although the advantages of such run-flat tires are very outstanding, they have also significant disadvantages, mainly: firstly, the tire noise is great and the comfort level is low in the automobile driving process. Secondly, when the tire passes through the pit ridge, because the sidewall is too thick and does not have enough avoidance space, the wire curtain of the sidewall of the tire is easy to break, so that the run-flat tire is easy to damage, especially the tire with larger flatness is easy to break, and the tire with larger flatness on the market is very expensive, so that the use cost is increased sharply.

In order to solve the above problems, there is a need for a tire that has the ability of adapting a common tire to poor road conditions and that will not cause instant tire pressure loss and vehicle runaway after being punctured by a foreign object.

SUMMERY OF THE UTILITY MODEL

In order to solve the current tire existence if in the background art the flat tire lead to the vehicle to be out of control in the twinkling of an eye easily, the anti ability of colliding with of run-flat child is weak, the child is made an uproar greatly, the problem with high use cost, the application provides a run-flat tire, through on the basis of current flat tire, combine traditional tire form, increase the inner tube design again, make the tire can compromise the anti grandma of flat tire simultaneously, anti ability of colliding with, can realize again that can continue to keep original state to go after the tire is pricked, avoid the tire to lose pressure in the twinkling of an eye to lead to the problem that the car is out of control.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

an explosion-proof tire comprises a hub and an outer tire arranged on the hub, wherein an inner tire is arranged in the outer tire and consists of a plurality of honeycomb airbags made of elastic rubber, any honeycomb airbag is connected with a branch air pipe used for inflating the honeycomb airbag, any branch air pipe is communicated with a main air pipe, and the free end of the main air pipe is hermetically connected with an air tap arranged on the hub; and a one-way valve for preventing gas from escaping is also arranged on any one of the branch gas pipes or in the honeycomb air bag.

The working and structural principles are briefly described as follows: the hub and the outer cover are nested with each other, the outer cover and the hub are fixed together by pressing through air pressure, the connection mode is completely the same as that of the existing commercially available tire and hub, but the difference is that the outer cover and the hub are sealed or not sealed. The vacuum tyre and the hub of the existing car on the market are sealed by contact, but the high-pressure tyre provided with the inner tube, such as the tyre of a motor coach or a large truck, the outer tyre and the hub are not sealed, and only the compression-resistant support effect is achieved. In the structure, whether the hub and the outer tire are sealed or not does not influence the normal use of the tire. The inner tube is different from the existing high-pressure inner bag in that the inner tube comprises a plurality of independently inflated honeycomb air bags, the air between the honeycomb air bag and another honeycomb air bag cannot be communicated with each other, the air can only enter any one honeycomb air bag in a one-way mode, and the air cannot automatically escape from the honeycomb air bag under the condition that the honeycomb air bag is complete. The main trachea is connected with the air cock of installing on wheel hub, when needs are aerifyd, loop through main trachea and the many bronchus of connection on main trachea with gas through the air cock, then fill gas into the honeycomb gasbag through the check valve, because the honeycomb gasbag has stronger plasticity and elastic deformation ability, therefore, under the inflation state, can the self-adaptation be full of the cavity between whole wheel hub and the cover tire between the honeycomb gasbag, make the inside pressurized of whole cover tire even, but local individual honeycomb gasbag leads to the honeycomb gasbag to damage the gas leakage because of external force effect or hard object puncture, adjacent honeycomb gasbag takes up the original space of gas leakage honeycomb gasbag with the self-adaptation inflation, make the holistic atmospheric pressure of tire still can keep to equivalent level. The smaller the individual space occupation of the honeycomb bladder, the more slight the overall tire pressure drop, and vice versa. By adopting the structure with the multi-honeycomb air bag, the serious consequences caused by the whole pressure loss of the tire and even the tire burst in the prior art due to the local air leakage can be avoided. In addition, the side wall of the outer tire is not different from that of the conventional common tire by adopting the structure of the multi-honeycomb air bag, the wall thickness of the side wall is much thinner than that of the conventional run-flat tire, so that when the tire passes through a hollow road surface, the problem that the outer tire is scrapped due to the fact that the ground and the hub are extruded and a wire curtain in the outer tire is broken is solved, and the use cost of the tire is greatly reduced.

In order to further facilitate the installation of the inner tube and eliminate pressure difference, so that the pressure of a cavity between the whole outer tube and the hub is uniform, preferably, the inner tube is composed of a plurality of longitudinally arranged honeycomb airbag units, is of a cuboid structure and is wound and filled in the cavity formed by the outer tube and the hub; any side wall of the inner tube is connected with the main air tube, and the branch air tube is arranged between two adjacent honeycomb air bag units.

Further preferably, the check valve is a duckbilled check valve made of silica gel or silicon rubber, and the duckbilled check valve comprises two silica gel sheets which are mutually attached and supply gas to flow in a one-way mode. The duckbill-shaped check valve is wedge-shaped and is provided with an upper soft silica gel sheet and a lower soft silica gel sheet which are mutually attached, the two silica gel sheets are integrally connected along the side wall of the length direction, only two ends of the two silica gel sheets are communicated, gas passes through the duckbill-shaped check valve, one end of the duckbill-shaped check valve close to the honeycomb airbag is mutually attached in a natural state, and when the gas passes through the duckbill-shaped check valve, the two silica gel sheets can be easily pushed open, so that the gas enters the honeycomb airbag; when pressure in the honeycomb gasbag is higher than the outside pressure of honeycomb gasbag, because the check valve is duckbilled type design, two silica gel pieces will receive great pressure for two tight extrusions of silica gel piece are in the same place, and the inside pressure of honeycomb gasbag is big more, and the silica gel piece is extruded more tightly, thereby sealed effect is better, avoids appearing leaking gas when using, the problem of gas leakage.

In order to make the air pressure distribution in the tire more uniform, the gravity center of the tire more uniform and reduce the tire noise during driving, preferably, the inner tube is composed of a first section, a middle section and a tail section, the transverse width of the first section is smaller than that of the tail section, the transverse width of the tail section is smaller than that of the middle section, the longitudinal length of the first section accounts for 10% -13% of the longitudinal total length of the inner tube, the longitudinal length of the middle section accounts for 75% -80% of the longitudinal length of the inner tube, and the remaining longitudinal length of the tail section is the longitudinal length of the inner tube. The purpose of adopting the structural design is to meet the internal structure of the existing wheel hub and tire, so that the wheel hub and tire of the existing automobile can be compatible, and the wheel hub and tire can be directly applied to the existing automobile tire, so that the practicability and the popularization degree of the automobile wheel hub structure are wider, and the automobile wheel hub structure is not limited by the existing automobile tire and wheel hub structure. Meanwhile, the tire is also suitable for small tires with light loads, such as bicycles, battery cars, motorcycles and the like.

Example 1:

with reference to the attached drawings 1-9 of the specification, the explosion-proof tire comprises a hub 1 and an outer cover 2 mounted on the hub 1, wherein an inner tube 3 is mounted in the outer cover 2, the inner tube 3 is composed of a plurality of honeycomb airbags 4, the honeycomb airbags 4 are made of elastic rubber, any honeycomb airbag 4 is connected with a branch tube 6 for inflating the honeycomb airbag 4, any branch tube 6 is communicated with a main air tube 5, and the free end of the main air tube 5 is hermetically connected with an air tap mounted on the hub 1; a one-way valve for preventing gas from escaping is also arranged on any one of the bronchus 6 or in the honeycomb air bag 4.

The working and structural principles are briefly described as follows: the hub 1 and the outer tyre 2 are nested with each other, and the outer tyre 2 and the hub 1 are fixed together by pressing through air pressure, the connection mode is completely the same as that of the existing commercially available tyre and hub, but the difference is that the outer tyre 2 and the hub 1 can be sealed or unsealed. The vacuum tyre and the hub of the existing car on the market are sealed by contact, but the high-pressure tyre provided with the inner tube, such as the tyre of a motor coach or a large truck, the outer tyre and the hub are not sealed, and only the compression-resistant support effect is achieved. In the above structure, whether the hub 1 and the outer tire 2 are sealed or not does not affect the normal use of the tire. The inner tube 3 is different from the existing high-pressure inner bag in that the inner tube 3 comprises a plurality of independently inflated cellular air bags 4, the air between one cellular air bag 4 and the other cellular air bag 4 cannot flow mutually, the air can enter any one cellular air bag 4 in a one-way mode, and the air cannot automatically escape from the cellular air bag 4 under the condition that the cellular air bag 4 is complete. The main air pipe 5 is connected with the air faucet installed on the hub 1, when the tire needs to be inflated, the air sequentially passes through the main air pipe 5 and the plurality of branch air pipes 6 connected to the main air pipe 5 through the air faucet, then the air is inflated into the honeycomb air bags 4 through the one-way valves, because the honeycomb air bags 4 have strong plasticity and elastic deformation capacity, therefore, in the inflated state, cavities between the whole hub 1 and the tire casing 2 can be filled with the honeycomb air bags 4 in a self-adaptive mode, the pressure inside the whole tire casing 2 is uniform, but when the local individual honeycomb air bags 4 are punctured due to external force or hard objects, the honeycomb air bags 4 are damaged to leak air, the adjacent honeycomb air bags occupy the original spaces of the air-leaking honeycomb air bags 4 through self-adaptive expansion, and the integral air pressure of the tire can still be kept to a considerable level. The smaller the individual space occupation of the cellular bladder 4, the more slightly the overall tire pressure drop, and vice versa. By adopting the structure of the multi-honeycomb air bag 4, the serious consequences caused by the whole pressure loss of the tire and even the tire burst in the prior art due to local air leakage can be avoided. In addition, the side wall of the outer tire 2 is enabled to be the same as that of the existing common tire by adopting the structure of the multi-honeycomb air bag 4, the wall thickness of the side wall is much thinner than that of the existing run-flat tire, so that when the tire passes through a hollow road surface, the problem that the outer tire 2 is scrapped due to the fact that the ground and the hub 1 are extruded and the wire curtain in the outer tire 2 is broken is not easily caused, and the use cost of the tire is greatly reduced. When a foreign object such as a nail punctures the outer tire 2, as shown in fig. 8, punctures one or more honeycomb air cells 4 in the inner tire 3, and when the honeycomb air cells 4 are punctured, the gas inside leaks rapidly, as shown in fig. 9. But at the same time, the surrounding unpunctured honeycomb air bag 4 will gradually expand under the action of air pressure to fill the space of the unpunctured honeycomb air bag, and the practical change is that the expansion degree of other honeycomb air bags 4 closer to the unpunctured honeycomb air bag 4 is larger, and the expansion degree of other honeycomb air bags farther away from the unpunctured honeycomb air bag 4 is smaller until the pressure inside the whole tire reaches the equilibrium position. Because the length of the foreign matter is always limited, and the puncturing direction is single, all the honeycomb air bags 4 cannot be punctured, and therefore, the whole air shortage of the tire cannot be caused due to the air leakage of the local honeycomb air bags, and the tire adopting the embodiment can effectively play an explosion-proof role.

Example 2:

on the basis of the embodiment 1, in order to further optimize the structure, the following aspects are improved: in order to further facilitate the installation of the inner tube 3 and eliminate pressure difference, so that the pressure of the cavity between the whole outer tube 2 and the hub 1 is uniform, in the embodiment, the inner tube 3 is composed of a plurality of longitudinally arranged honeycomb airbag units, the whole inner tube 3 is of a cuboid structure and is wound and filled in the cavity formed by the outer tube 2 and the hub 1; any side wall of the inner tube 3 is connected with the main air tube 5, and the branch air tube 6 is arranged between two adjacent honeycomb air bag units.

In this embodiment, in order to facilitate the manufacture and installation of the inner tube, the honeycomb airbag unit is composed of a plurality of transversely arranged honeycomb airbags 4 on the premise of satisfying uniform inflation.

Further preferably, the check valve is a duckbilled check valve made of silica gel or silicon rubber, and the duckbilled check valve comprises two silica gel sheets which are mutually attached and supply gas to flow in a one-way mode. The duckbill-shaped check valve is wedge-shaped and is provided with an upper soft silica gel sheet and a lower soft silica gel sheet which are mutually attached, the two silica gel sheets are integrally connected along the side wall of the length direction, only two ends of the two silica gel sheets are communicated, gas passes through the duckbill-shaped check valve, one end of the duckbill-shaped check valve, which is close to the honeycomb airbag 4, is mutually attached in a natural state, and when the gas passes through the duckbill-shaped check valve, the two silica gel sheets can be easily pushed open, so that the gas enters the honeycomb airbag 4; when pressure in the honeycomb gasbag 4 is higher than the outside pressure of honeycomb gasbag 4, because the check valve is duckbilled type design, two silica gel pieces will receive great pressure for two tight extrusions of silica gel piece are in the same place, and the inside pressure of honeycomb gasbag 4 is big more, and the silica gel piece is extruded more tightly, thereby sealed effect is better, avoids appearing leaking gas when using, the problem of running out of gas.

In order to make the air pressure distribution inside the tire more uniform, the gravity center of the tire more uniform, and reduce the tire noise during driving, preferably, the inner tube 3 is composed of a first section, a middle section, and a tail section, the lateral width of the first section is smaller than that of the tail section, the lateral width of the tail section is smaller than that of the middle section, the longitudinal length of the first section accounts for 10% -13% of the longitudinal total length of the inner tube 3, the longitudinal length of the middle section accounts for 75% -80% of the longitudinal length of the inner tube 3, and the remaining is the longitudinal length of the tail section. The purpose of adopting the structural design is to meet the internal structure of the existing wheel hub and tire, so that the wheel hub and tire of the existing automobile can be compatible, and the wheel hub and tire can be directly applied to the existing automobile tire, so that the practicability and the popularization degree of the automobile wheel hub structure are wider, and the automobile wheel hub structure is not limited by the existing automobile tire and wheel hub structure. It should be noted that the above-mentioned structural configuration is only an optimized design solution, and does not impose any limitation or limitation on the reliable implementation of the present invention.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
