The invention provides a tire protection method, please refer to fig. 5, fig. 5 is a flow chart of a first embodiment of the tire protection method according to the invention, the tire protection method comprises the following steps:

step S10: judging whether the tyre of the vehicle is damaged;

step S20: if the tire is damaged, sleeving the tire sleeve outside the tire;

step S30: the clamping assembly is clamped on the hub of the tire;

step S40: and (3) inflating the inflation cavity to expand and bulge the tire sleeve.

Referring to fig. 1 and 2, the present invention further provides a spare tire, which includes a tire casing 10 and a clamping assembly 20, wherein the tire casing 10 is used for being sleeved on a tire, the tire casing 10 is internally provided with an inflating cavity 13, the tire casing 10 includes an inner tire layer 11 and an outer tire layer 12, and the inner tire layer 11 is used for being abutted against a crown 30 of the tire; the carcass ply 12 is intended to be in contact with the ground; the clamping assembly 20 is arranged on the inner tire layer 11, and the clamping assembly 20 is used for clamping with a hub 40 of the tire.

When the tire is broken, the tire air pressure drops rapidly. The vehicle owner can judge whether the tyre of the vehicle is damaged or not by displaying the detected tyre pressure on the central control system.

When the tire is damaged, the air in the tire can be pumped out, so that the tire is reduced to the preset tire pressure, and the tire sleeve is more convenient to install.

The standby protection tire according to the present embodiment may be provided with an air pump 50, and the air pump 50 is a suction-integrated air pump 50. When the tire is broken, the air pump 50 is connected to the valve of the tire through the air pipe 51 to pump out the air in the tire, thereby pumping out the air in the tire.

The vehicle owner may also operate with other air extraction or inflation devices.

Referring to fig. 3, the spare tire is further equipped with a tire pressure detector. In order to improve the convenience of operation, the air pressure in the tire can be detected in real time through the tire pressure detector when the air in the tire is pumped out, so that the air pressure in the tire is minimized, and the tire is ensured to be in a minimum volume state. The preset tire pressure may be set to less than 2bar.

After the air in the tire is extracted, the sleeve 10 can be mounted on the tire.

Specifically, step S10 includes:

step S11: sleeving the tire sleeve part on the top outside the tire in a mode that the inner tire layer faces inwards;

step S12: rotating the tire, and rotating the top position of the tire jacket provided with the tire jacket to the bottom of the tire;

step S13: sleeving the rest part of the tire sleeve at the rest position of the tire along the circumferential direction of the tire until the tire sleeve is completely sleeved outside the tire in a surrounding manner;

the tire sleeve 10 is annular, the inner annular surface is the inner tire layer 11, and the outer annular surface is the outer tire layer 12. When the sleeve 10 is mounted on a tire, the inner layer 11 is first fitted over the upper half of the tire and the locking assembly 20 is locked to the rim of the tire hub 40.

The idle speed starts the vehicle to drive forwards, so that the tire can rotate forwards or backwards for half a turn. The running length can be adjusted according to the size of the tire, and for a common household car, the tire can be rotated by half a turn by operating the vehicle to run forwards or backwards for about 1 m.

After rotation, the other half of the inner tube layer 11 is sleeved on the other half of the tire, and the clamping assembly 20 is clamped on the rim of the tire hub 40, so that the clamping assembly 20 on the whole tire sleeve 10 is stably connected on the rim of the tire hub 40. Thereby ensuring the stability of the connection of the sleeve 10.

When the coupling of the casing 10 is completed, the air pump 50 inflates the inflation chamber 13. After inflation, the sleeve 10 expands, causing the carcass 12 to expand, the carcass 12 directly contacting the ground, and acting as a support structure to support the vehicle for continued travel on the ground.

The tyre sleeve 10 can cause larger friction force between the inner tyre layer 11 and the tyre crown 30 under the expansion of air pressure, the tyre sleeve 10 can be made of rubber materials, the friction force between the tyre sleeve 10 is further improved, and the tyre sleeve 10 is prevented from slipping or falling off. While also enabling the clamping assembly 20 to be clamped more tightly with the rim of the tire hub 40.

The tire pressure detector detects the air pressure in the inflation cavity 13, and the inflation cavity 13 is inflated to the standard air pressure and then stopped, and at this time, the tire casing 10 can temporarily meet the running condition of the vehicle. The car owner only needs to travel at a low speed to the nearest repair shop for repair.

When the sleeve 10 needs to be removed, the air in the inflation chamber 13 is also pumped out by the air pump 50. The carcass 12 relaxes from the inner carcass 11 to facilitate the removal of the clasp assembly from the rim of the tire hub 40 by the vehicle owner.

It will be appreciated that when the clasp assembly is removed, the clasp assembly is removed from the upper half turn, and the clasp assembly is removed from the remainder after the idle running vehicle turns the tire half turn.

The removed tire case 10 is cleaned and stored, and the tire case 10 can be reused.

According to the technical scheme, the tire sleeve 10 can be sleeved on a tire, and the tire sleeve 10 is inflated, so that the tire sleeve 10 is opened. The inner tire layer 11 is abutted against the crown 30 of the tire, and is clamped and fixed with the hub 40 of the tire through the clamping assembly 20, and the outer tire layer 12 is used for normal running on the bottom surface. The tire sleeve 10 is simple to operate, and solves the problems of difficult replacement, large volume and heavy weight of a conventional spare tire; meanwhile, the tire pressure monitoring and the corrosion of the tire rubber by the tire repairing sleeve 10 are avoided; the emergency correspondence of the tire air leakage is completed with low cost and high efficiency.
