[0002] Most of the fuel vehicles are equipped with full-size or non-full-size spare tires, and then equipped with a jack and a wrench, but now it is more difficult for most women and some men with poor hands-on ability to replace the spare tire, and the spare tire occupies the space of the vehicle, increases the weight of the whole vehicle, and increases the fuel consumption of the fuel vehicle.

[0003] Therefore, in recent years, the market share of electric vehicles has gradually expanded, and they are also favored by customers. Considering the vehicle space and the range of electric vehicles, most electric vehicles replace the spare tire with a tire repair kit, including a pump and tire repair liquid. As long as the tire repair liquid is pumped into the tire by the pump, the tire can be repaired. However, the tire repair liquid has a certain corrosive effect on the tire monitor and the rubber of the tire, and the tire pressure monitor needs to be replaced after using the tire repair tool, and even the tire needs to be replaced. The tire repair kit can only repair small holes in the tire, and it is ineffective if the tire is punctured or damaged by a large foreign object. The tire repair liquid can only be used once, and needs to be reconfigured after use.

[0004] In addition, high-end brand vehicles use run-flat tires, which can allow the tire to run at low speed to the nearby repair shop even if the tire is leaking or punctured. However, compared with ordinary tires, run-flat tires are more expensive and more difficult to repair. SUMMARY

[0055] This invention proposes a tire protection method, please refer to... Figure 5 , Figure 5 This is a schematic flowchart of the first embodiment of the tire protection method of the present invention, which includes the following steps:

[0056] Step S10: Determine if the vehicle's tires are damaged;

[0057] Step S20: If the tire is damaged, put a tire cover over the tire;

[0058] Step S30: Snap the snap-fit ​​assembly onto the rim of the tire;

[0059] Step S40: Inflate the inflation chamber to make the tire cover bulge.

[0060] Please refer to Figure 1 and Figure 2 The present invention also provides a spare protective tire, the spare protective tire including a tire cover 10 and a snap-fit ​​assembly 20. The tire cover 10 is used to be fitted onto the tire. The tire cover 10 has an inflation chamber 13 inside. The tire cover 10 includes an inner tire layer 11 and an outer tire layer 12. The inner tire layer 11 is used to abut against the tire crown 30. The outer tire layer 12 is used to contact the ground. The snap-fit ​​assembly 20 is disposed on the inner tire layer 11 and is used to snap onto the tire rim 40.

[0061] When a tire is punctured, the tire pressure drops rapidly. The driver can then determine whether the tires are damaged by checking the tire pressure displayed on the central control system.

[0062] When a tire is damaged, the air inside the tire can be extracted to reduce the tire pressure to a preset level, making it easier to install the tire cover.

[0063] The spare protective tire described in this embodiment may be equipped with an air pump 50, which is an integrated suction and extraction air pump 50. When the tire is damaged and the tire pressure drops rapidly, the air pump 50 is connected to the tire valve through the air pipe 51 to extract the air from the tire.

[0064] Car owners can also operate using other air extraction or inflation devices.

[0065] Please refer to Figure 3 The spare protective tire is also equipped with a tire pressure monitoring system. To improve ease of operation, the tire pressure can be monitored in real time while air is being removed from the tire, ensuring the tire is at its minimum pressure and its volume is minimized. The preset tire pressure can be set to less than 2 bar.

[0066] After the air inside the tire is removed, the tire cover 10 can be installed on the tire.

[0067] Specifically, step S10 includes:

[0068] Step S11: With the inner tube facing inward, fit the tire sleeve portion onto the top of the tire.

[0069] Step S12: Rotate the tire so that the top position of the tire sleeve is rotated to the bottom of the tire;

[0070] Step S13: Along the circumference of the tire, fit the remaining portion of the tire cover onto the remaining positions of the tire until the tire cover is completely wrapped around the outside of the tire;

[0071] The tire sleeve 10 is annular, with the inner ring surface being the inner tire layer 11 and the outer ring surface being the outer tire layer 12. When installing the tire sleeve 10 on the tire, the inner tire layer 11 is first placed on the upper half of the tire, and the snap-fit ​​assembly 20 is snapped into place with the rim of the tire hub 40.

[0072] Drive the vehicle forward at idle speed, rotating the tires half a turn forward or backward. The distance traveled can be adjusted according to the tire size. For a typical family sedan, driving the vehicle forward or backward for about 1 meter will rotate the tires half a turn.

[0073] After rotation, the other half of the inner tube layer 11 is fitted onto the other half of the tire, and at the same time, the snap-fit ​​assembly 20 is snapped onto the rim of the tire hub 40, so that the snap-fit ​​assembly 20 on the entire tire sleeve 10 is stably connected to the rim of the tire hub 40. This ensures the stability of the connection of the tire sleeve 10.

[0074] After the tire sheath 10 is connected, the air pump 50 inflates the inflation chamber 13. After inflation, the tire sheath 10 expands, causing the outer tire layer 12 to open and directly contact the ground, serving as a support structure to support the vehicle to continue driving on the ground.

[0075] Under air pressure, the tire sleeve 10 will generate greater friction between the inner tire layer 11 and the tire crown 30. The tire sleeve 10 can be made of rubber to further increase the friction and prevent the tire sleeve 10 from slipping or falling off. At the same time, it also allows the snap-fit ​​assembly 20 to snap more tightly onto the rim of the tire hub 40.

[0076] The tire pressure sensor detects the air pressure inside the inflation chamber 13. Inflation is stopped after the chamber is inflated to the standard pressure. At this point, the tire sleeve 10 is sufficient for the vehicle's driving needs. The owner only needs to drive at low speed to the nearest repair shop for repairs.

[0077] When the tire cover 10 needs to be removed, the air in the inflation chamber 13 is also extracted by the air pump 50. The outer tire layer 12 and the inner tire layer 11 are loosened, making it easier for the vehicle owner to remove the clip assembly from the rim of the tire hub 40.

[0078] It is understood that when removing the clip assembly, the upper half of the clip assembly is removed first, and after the vehicle is driven at idle speed to rotate the tire half a turn, the remaining part of the clip assembly is removed.

[0079] The removed tire cover 10 is cleaned and stored, and the tire cover 10 can be reused.

[0080] The present invention provides a tire cover 10 that is fitted onto the tire and inflated to open it. The inner tire layer 11 abuts against the tire crown 30 and is secured to the tire rim 40 via the snap-fit ​​assembly 20. The outer tire layer 12 is used for normal driving on the ground. The tire cover 10 is simple to operate, solving the problems of difficult, bulky, and heavy conventional spare tire replacement; it also avoids the corrosion of tire pressure monitoring and tire rubber caused by the tire cover 10; reducing costs and efficiently responding to tire leaks.

[0081] Further, please refer to Figure 6 , Figure 6 This is a schematic flowchart of the second embodiment of the tire protection method of the present invention. Step S20 includes:

[0082] Step S21: Secure one edge of the inner tube ply to the inner rim of the wheel hub using the snap-fit ​​assembly, and secure the other edge of the inner tube ply to the outer rim of the wheel hub using the snap-fit ​​assembly.

[0083] The snap-fit ​​assembly 20 includes a first snap-fit ​​block 21 and a second snap-fit ​​block 22. The first snap-fit ​​block 21 is disposed on one side edge of the inner tube layer 11. When the inner tube layer 11 is connected to the tire crown 30, the first snap-fit ​​block 21 snaps onto the inner rim of the wheel hub 40. The second snap-fit ​​block 22 is disposed on the other side edge of the inner tube layer 11. When the inner tube layer 11 is connected to the tire crown 30, the second snap-fit ​​block 22 snaps onto the outer rim of the wheel hub 40.

[0084] The inner tube layer 11 has a certain thickness. When the tire sleeve 10 is installed, one edge of the inner tube layer 11 faces outward and the other edge faces inward. The first snap-fit ​​block 21 is located on the outward edge, and the second snap-fit ​​block 22 is located on the inward edge.

[0085] The first locking block 21 and the second locking block 22 may adopt a chamfered or other structure. The specific shape needs to be adjusted according to the shape of the wheel hub 40 to ensure that the first locking block 21 and the second locking block 22 can be stably locked onto the rim of the wheel hub 40.

[0086] Both the first snap-fit ​​block 21 and the second snap-fit ​​block 22 are integrally formed with the tire sleeve 10, thereby improving the connection strength between the first snap-fit ​​block 21, the second snap-fit ​​block 22, and the inner tire layer 11. At the same time, the first snap-fit ​​block 21 and the second snap-fit ​​block 22 are also made of rubber, giving them certain deformation properties and facilitating installation by the vehicle owner.

[0087] After installation, the pressure of air expansion is used to fix the device, preventing the first locking block 21 and the second locking block 22 from deforming and falling off during driving.

[0088] To improve the ease of operation for vehicle owners, the spare protective tire cover 10 is equipped with all the tools needed for installing the tire cover 10, such as a portable air pump 50 and an air hose 51. In addition, the spare protective tire cover 10 also includes a tire pressure sensor, which is used to detect the air pressure inside the inflation chamber 13 and the tire pressure.

[0089] To facilitate the owner's inflation of the tire cover 10, a limiting connector is provided on the air pipe 51, and a limiting buckle is provided on the air hole 14. When the air pipe 51 is connected to the air hole 14, the limiting connector is engaged with the limiting buckle.

[0090] The limiting buckle and the limiting connector can be connected by a threaded connection, so that the limiting structure is tightened into the limiting buckle to prevent the air tube 51 from falling off due to the air pressure in the inflation chamber 13 during the inflation process, thereby improving the stability of the connection during the inflation process.

[0091] Further, please refer to Figure 7 , Figure 7 This is a schematic flowchart of the third embodiment of the tire protection method of the present invention. Step S40 includes:

[0092] Step S41: When inflating the inflation chamber, the air pressure value inside the tire sheath is detected;

[0093] Step S42: Determine whether the air pressure in the inflation chamber has reached the preset air pressure;

[0094] Step S43: When the air pressure value reaches the preset air pressure, stop inflating the air chamber.

[0095] Under air pressure, the tire sleeve 10 will generate greater friction between the inner tire layer 11 and the tire crown 30. The tire sleeve 10 can be made of rubber to further increase the friction and prevent the tire sleeve 10 from slipping or falling off. At the same time, it also allows the snap-fit ​​assembly 20 to snap more tightly onto the rim of the tire hub 40.

[0096] The preset air pressure can be set to the current air pressure of an external inflator, and this data can be obtained in real time via a network connection. The tire pressure sensor detects the air pressure inside the inflation chamber 13, and inflation is stopped after the chamber is inflated to the preset air pressure. At this point, the tire sleeve 10 is sufficient to temporarily meet the vehicle's driving requirements. The vehicle owner only needs to drive at low speed to the nearest repair shop for repairs.

[0097] Further, please refer to Figure 8 , Figure 8 This is a schematic flowchart of the fourth embodiment of the tire protection method of the present invention. After step S40, it further includes:

[0098] Step S50: After the vehicle uses the temporary tires to move to the preset position, the vehicle is braked;

[0099] Step S60: Remove the tire cover from the tire;

[0100] Step S70: Replace the tire.

[0101] The tire covers 10 can only meet the temporary driving needs of the vehicle and cannot be used for extended periods. Therefore, the vehicle's current location is recorded using an onboard map.

[0102] When the vehicle arrives at the designated repair shop, the owner needs to remove the tire covers 10.

[0103] Specifically, step S60 includes:

[0104] Step S61: Extract the gas from the inflation chamber;

[0105] Step S62: Remove the snap-fit ​​assembly from the wheel hub;

[0106] Step S63: Remove the portion of the tire cover that is fitted onto the top of the tire;

[0107] Step S64: Rotate the tire so that the bottom of the tire cover that has not been removed is rotated to the top of the tire, so that the outer tire layer is lifted off the ground;

[0108] Step S65: Remove the remaining portion of the tire cover from the rest of the tire along the circumference of the tire.

[0109] When the tire cover 10 needs to be removed, the air in the inflation chamber 13 is also extracted by the air pump 50. The outer tire layer 12 and the inner tire layer 11 are loosened, making it easier for the vehicle owner to remove the clip assembly from the rim of the tire hub 40.

[0110] It is understood that when removing the clip assembly, the upper half of the clip assembly is removed first, and after the vehicle is driven at idle speed to rotate the tire half a turn, the remaining part of the clip assembly is removed.

[0111] The removed tire cover 10 is cleaned and stored, and the tire cover 10 can be reused.

[0112] Further, please refer to Figure 4 It also includes a storage box 60, which has a fan-shaped storage cavity for storing the spare protective tire and a rectangular storage cavity for storing the air pump 50 and the air pipe 51.

[0113] It is understood that the tire cover 10 is ring-shaped. Therefore, after folding, the tire cover 10 is in an arc shape. To improve the utilization of storage space, a storage box 60 is provided specifically for storing the tire cover 10, air pump 50, air hose 51, and tire pressure monitor.

[0114] The storage box 60 is fan-shaped, and its edges are arc-shaped, so the folded tire cover 10 can be stored at the edge of the storage box 60, avoiding taking up too much space.

[0115] It is understood that the tire cover 10 is arc-shaped, and does not occupy the space near the center of the storage box 60, thus allowing the air pump 50, tire pressure detector, and power supply to be stored there. This improves space utilization and avoids excessive storage space occupation.

[0116] Specifically, the storage box 60 includes a first connecting plate 61, a second connecting plate 62, an arc-shaped plate 63, a first partition plate 64, and a second partition plate 65. One end of the first connecting plate 61 is connected to one end of the arc-shaped plate 63, and the other end of the first connecting plate 61 is connected to one end of the second connecting plate 62. The other end of the second connecting plate 62 is connected to the other end of the arc-shaped plate 63 to form the fan-shaped storage cavity. One end of the first partition plate 64 is connected to the first connecting plate 61, and the other end of the first partition plate 64 is connected to one end of the second partition plate 65. The other end of the second partition plate 65 is connected to the second connecting plate 62 to form the rectangular storage cavity.

[0117] The first connecting plate 61, the second connecting plate 62, and the arc-shaped plate 63 are connected end to end to form a fan-shaped structure.

[0118] A rectangular storage cavity is created at the center of the storage box 60 by the first partition plate 64 and the second partition plate 65.

[0119] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
