[0002] With the development of science and technology, the demand and application of automobiles are gradually increasing. At the same time, avoiding unexpected situations during the driving of automobiles has gradually become a problem that needs to be paid attention to and solved. Tires are one of the important accessories in the driving process of automobiles. Solving unexpected situations during the driving of tires can greatly improve the safety of automobiles during driving. The airbags in the prior art can only solve the problem of tire blowout during driving, and cannot solve the problem of rapid leakage or deflation of tires due to encountering sharp objects. Since the conditions for the deployment of explosion-proof airbags are not met at this time, if the explosion-proof airbags are not deployed and the driver does not prepare a spare tire before traveling, the car will lose its ability to move. If the car is to continue driving, it can only rely on the support of the rim inside the tire, but this method will damage the rim to a certain extent, which not only reduces the safety of travel, but also increases the maintenance cost.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, mainly refers to a physical structural connection, and may also include meanings such as direct connection or indirect connection when specified. The terms "first" and "second" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "includes" and any variations thereof are intended to cover non-exclusive inclusions.

[0026] See also Figure 1 , Figure 11 is a schematic block diagram of a car 100 in an embodiment of the present application. The car 100 includes a tire 200 .

[0027] Therefore, the automobile 100 can continue to travel after the tire 200 is leaking or deflated, and the automobile 100 can continue to travel to a maintenance point for maintenance, thereby ensuring the safety and smooth travel of the driver.

[0028] Please also read Figure 2 and Figure 3 , Figure 2 is a partial three-dimensional structural diagram of a tire 200 in an embodiment of the present application, Figure 3 1 is a partial structural diagram of a tire 200 in another direction in an embodiment of the present application. The tire 200 is applied to a car 100, and the tire 200 includes a rim 1 and an airbag device 3. A mounting groove 11 is provided at the outer ring of the rim 1. The airbag device 3 includes an inflatable airbag 31, a detector 32 and a controller 33. The inflatable airbag 31 is installed around the mounting groove 11. The inflatable airbag 31 is used to be deployed when the tire 200 is leaking or deflated, so as to adjust the tire pressure inside the tire 200 at this time so that the car 100 continues to travel. The detector 32 is provided inside the tire 200 to detect the tire pressure. The controller 33 is used to control the inflatable airbag 31 to be deployed according to the tire pressure, or to control the inflatable airbag 31 not to be deployed.

[0029] Thus, the detector 32 detects the tire pressure inside the tire 200, so that the controller 33 determines the state of the inflatable airbag 31 according to the tire pressure, and controls the inflatable airbag 31 to be deployed when the tire 200 is leaking or deflated, and then adjusts the tire pressure inside the tire 200 by the deployed inflatable airbag 31, so that the tire 200 can continue to drive after leaking or deflated, and the car 100 can continue to drive to a maintenance point for maintenance, thereby avoiding accidents caused by the car 100 during driving, ensuring the safety and smoothness of the driver's travel, improving the safety of travel and the endurance of the car 100, and avoiding the tire 200 from running for a long time when it is leaking or deflated, thereby damaging the rim 1, and reducing maintenance costs.

[0030] In some embodiments, when the inflatable airbag 31 is not installed in the mounting groove 11, the inflatable airbag 31 is in the shape of an elongated strip. The inflatable airbag 31 is installed in the mounting groove 11 by winding a fixed steel wire or a steel cable. When the inflatable airbag 31 is installed in the mounting groove 11, it is tightly connected to the mounting groove 11 and does not generate relative movement.

[0031] It is understandable that the tire 200 may be a vacuum tire (not shown) that integrates an inner tube (not shown) and an outer tube 2. Figure 2Only the outer tire 2 is shown, which may also be illustrated as a vacuum tire), or it may be a tire 200 in which the inner tube and the outer tire 2 are separately arranged, wherein the inner tube is installed between the outer tire 2 and the inflatable airbag 31.

[0032] As mentioned above, in some embodiments, when the detector 32 detects that the change in tire pressure is less than a preset value, the controller 33 determines that the tire 200 is leaking or deflated. At this time, the controller 33 controls the inflatable airbag 31 to deploy. When the inflatable airbag 31 is deployed, the inflatable airbag 31 occupies a certain space inside the tire 200, thereby increasing the tire pressure of the tire 200 after leaking or deflated, so that the tire 200 continues to travel. When the detector 32 detects that the change in tire pressure is greater than or equal to the preset value, the controller 33 controls the inflatable airbag 31 not to deploy.

[0033] The side of the inflatable airbag 31 close to the rim 1 is a first side 316 , and the side of the inflatable airbag 31 away from the rim 1 is a second side 317 .

[0034] See also Figure 4 and Figure 5 , Figure 4 Schematic diagram of the planar structure of the first surface 316 of the inflatable airbag 31 in the embodiment of the present application. Figure 5 Schematic diagram of the planar structure of each airbag bag 311 in the embodiment of the present application. Figure 2 , Figure 4 and Figure 5 As shown, the inflatable airbag 31 includes a plurality of airbag bags 311, and the plurality of airbag bags 311 are arranged in sequence along the circumference of the mounting groove 11, each airbag bag 311 includes a first end 3111 and a second end 3112, and the distance between the first ends 3111 of each two adjacent airbag bags 311 is less than the length of each airbag bag 311.

[0035] Thus, the multiple airbag bags 311 can be deployed to a corresponding degree under the control of the controller 33 according to the detected tire pressure, that is, some of the multiple airbag bags 311 can be deployed to better and more accurately adjust the tire pressure in the tire 200, and the distance between the first ends 3111 of each two adjacent airbag bags 311 is smaller than the length of each airbag bag 311, so that the deployment of the multiple airbag bags 311 does not affect each other.

[0036] Among them, Figure 4 and Figure 5 As shown, the dotted lines in the figure indicate the covered portion of each airbag bag 311.

[0037] Please also read Figure 6 , Figure 6FIG. 3 is a schematic diagram of the planar structure of the second surface 317 of the inflatable airbag 31 in the embodiment of the present application. Figure 4 and Figure 6 As shown, the inflatable airbag 31 also includes an inflating hose 312 and an inflator (not shown in the figure), the inflating hose 312 is arranged on one side of the inflatable airbag 31 and connected to the multiple airbag bags 311, the inflator is located outside the tire 200 and adjacent to the tire 200, the inflator is connected to the inflating hose 312 to inflate the multiple airbag bags 311, and the controller 33 is also used to control the inflator to inflate or stop inflating and the inflation time of the inflator.

[0038] Thus, the inflator inflates the multiple airbag bags 311 through the inflation hose 312, providing an inflation path to better enable the inflatable airbags 31 to be deployed to a certain extent, and the controller 33 controls the deployment degree of the multiple airbag bags 311 by controlling the inflator to inflate or stop inflating and the inflation time of the inflator.

[0039] In some embodiments, Figure 4 As shown, the inflatable hose 312 is arranged on a side with a longer edge in the inflatable airbag 31 to better connect the multiple airbag bags 311. The side with a longer edge is parallel to the circumferential direction of the rim 1.

[0040] In some embodiments, Figure 4 and Figure 6 As shown, the inflation hose 312 includes a first inflation hose 3121 and a second inflation hose 3122. The first inflation hose 3121 is installed in a surrounding manner in the installation groove 11, one end of the second inflation hose 3122 is connected to the first inflation hose 3121, and the other end of the second inflation hose 3122 is connected to the inflator. The inflator fills the first inflation hose 3121 with gas through the second inflation hose 3122.

[0041] Thus, the second inflation hose 3122 is the total path for the inflator to deliver gas, and the first inflation hose 3121 and the inflatable airbag 31 are installed together in the installation groove 11 to facilitate the inflator to inflate the inflatable airbag 31.

[0042] In some embodiments, when the inflatable airbag 31 is not deployed, the second inflatable hose 3122 is not connected to the inflator, and the inflator does not rotate with the tire 200. When the inflatable airbag 31 is deployed, the second inflatable hose 3122 is connected to the inflator, and the inflator rotates with the tire 200.

[0043] In some embodiments, Figure 4 As shown, when the inflatable airbag 31 is in the shape of a long flat strip, the second inflatable hose 3122 is disconnected from a certain position, and both ends of the disconnected second inflatable hose 3122 can be through holes or closed holes.

[0044] In some embodiments, Figure 4 and Figure 5 As shown, the multiple airbag bags 311 are provided with multiple inflation holes 3113 on one side close to the first inflation hose 3121, and the first inflation hose 3121 is provided with multiple air outlet holes 3123 at positions corresponding to the multiple inflation holes 3113. The multiple air outlet holes 3123 are correspondingly connected to the multiple inflation holes 3113, and the gas filled into the first inflation hose 3121 by the inflator is used to enter the multiple airbag bags 311 through the multiple air outlet holes 3123 and the multiple inflation holes 3113.

[0045] Therefore, the provision of the multiple inflation holes 3113 and the multiple air outlet holes 3123 enables the inflator to more conveniently inflate the multiple airbag bags 311 to control the degree of deployment of the multiple airbag bags 311 .

[0046] In some embodiments, Figure 4 and Figure 5 As shown, a plurality of one-way valves 34 are arranged between the plurality of air outlet holes 3123 and the plurality of inflation holes 3113, for allowing the gas in the first inflation hose 3121 to flow into the plurality of airbag bags 311 along a first direction 38, wherein the first direction 38 is the direction from the plurality of air outlet holes 3123 to the corresponding plurality of inflation holes 3113.

[0047] Thus, the multiple one-way valves 34 can prevent gas from flowing out in the opposite direction of the first direction 38 to ensure the inflation speed and deployment degree of the multiple airbag bags 311 and avoid gas backflow that affects the inflation of the inflator.

[0048] In some embodiments, Figure 4 and Figure 6 As shown, the inflatable airbag 31 further includes a buffer device 35, and the buffer device 35 is arranged on the second inflating hose 3122 to release the inflation pressure of the inflator.

[0049] Thus, the buffer device 35 releases the inflation pressure generated by the inflator during inflation, that is, it shares the inflation pressure to a certain extent, thereby avoiding damage to the inflation hose 312 and the multiple airbag bags 311 due to the inflation pressure, and can also more accurately control the deployment degree of the inflatable airbag 31.

[0050] In some embodiments, Figure 4 and Figure 5 As shown, the inflatable airbag 31 also includes a plurality of hose connectors 313, one side of each hose connector 313 is connected to a side of each airbag bag 311 close to the first inflatable hose 3121, and the first inflatable hose 3121 passes through the plurality of hose connectors 313 to correspondingly connect the plurality of airbag bags 311.

[0051] Thus, the multiple hose connectors 313 can make the first inflation hose 3121 close to the multiple airbag bags 311, so that the multiple air outlet holes 3123 are correspondingly connected to the multiple inflation holes 3113, thereby improving the stability of the first inflation hose 3121 connecting to the multiple airbag bags 311.

[0052] In some embodiments, the multiple hose connectors 313 are made of cloth, and in the portion where the first inflation hose 3121 passes through the multiple hose connectors 313, the multiple hose connectors 313 are configured to be double-layer cloth, wherein the multiple hose connectors 313 can be flexibly deformed as needed.

[0053] It is understandable that the multiple hose connectors 313 can be made of, but not limited to, cloth. The multiple hose connectors 313 can also be made of plastic, etc., which is not limited here.

[0054] Please also read Figure 7 and Figure 8 , Figure 7 Schematic diagram of the planar structure of the third surface 378 of the explosion-proof airbag 37 in the embodiment of the present application. Figure 8 FIG. 3 is a schematic diagram of the planar structure of the fourth surface 379 of the explosion-proof airbag 37 in the embodiment of the present application. Figure 7 and Figure 8 As shown, the airbag device 3 also includes an explosion-proof airbag 37, which is used to be deployed when the tire 200 bursts. The explosion-proof airbag 37 includes a first connection part 371, a second connection part 372, a third connection part 373 and a fourth connection part 374. The first connection part 371 and the second connection part 372 are arranged on one side of the explosion-proof airbag 37, and the third connection part 373 and the fourth connection part 374 are arranged on the other side of the explosion-proof airbag 37, wherein the first connection part 371 corresponds to the position of the third connection part 373, and the second connection part 372 corresponds to the position of the fourth connection part 374, the first connection part 371 is connected to the third connection part 373, and the second connection part 372 is connected to the fourth connection part 374, so that the explosion-proof airbag 37 is installed around the inflatable airbag 31.

[0055] Therefore, the airbag device 3 can deploy the explosion-proof airbag 37 at the moment when the tire 200 bursts, and can also deploy the inflatable airbag 31 when the tire 200 is leaking or deflated, so that the tire 200 can continue to travel under different unexpected situations, thereby improving the smoothness and safety of travel, and preventing the tire 200 from continuing to travel in the event of a burst without the explosion-proof airbag 37 and damaging the rim 1, thereby reducing maintenance costs.

[0056] When the explosion-proof tire 200 is deployed and the tire pressure inside the tire 200 is still insufficient, the controller 33 controls the inflatable airbag 31 to deploy.

[0057] It can be understood that the first connection part 371, the second connection part 372, the third connection part 373 and the fourth connection part 374 can be connected to each other by glue or by sewing technology, which is not limited here.

[0058] As mentioned above, the side of the explosion-proof airbag 37 close to the rim 1 is the third side 378 , and the side of the explosion-proof airbag 37 away from the rim 1 is the fourth side 379 .

[0059] In some embodiments, Figure 7 As shown, the explosion-proof airbag 37 also includes a generator 375, and the generator 375 is movably connected to one side of the explosion-proof airbag 37. The generator 375 includes an air inlet 3751. The generator 375 detects the tire pressure in the tire 200 through the gas entering the air inlet 3751. The controller 33 determines whether the tire 200 is blown out or not according to the tire pressure detected by the generator 375, and then controls the explosion-proof airbag 37 to be deployed or not.

[0060] Thus, the controller 33 determines the state of the tire 200 according to the tire pressure detected by the generator 375, and then accurately controls the deployment or non-deployment of the explosion-proof airbag 37, limits the conditions for the deployment of the explosion-proof airbag 37, and improves the accuracy of the deployment of the explosion-proof airbag 37 in specific situations.

[0061] In some embodiments, the generator 375 further includes an air outlet 3752 , and the air outlet 3752 is used to discharge the gas entering the generator 375 . The generator 375 is clamped and connected to one side of the explosion-proof airbag 37 by a clamp 376 .

[0062] As mentioned above, when the change in tire pressure detected by the generator 375 is greater than or equal to a preset value in an instant, the controller 33 controls the explosion-proof airbag 37 to deploy.

[0063] In some embodiments, Figure 8As shown, the dotted line in the figure indicates the folding line of the explosion-proof airbag 37. The explosion-proof airbag 37 is folded along the folding line so that the explosion-proof airbag 37 is adapted to the width of the tire 200 to better achieve the effect of the explosion-proof airbag 37.

[0064] In some embodiments, the explosion-proof airbag 37 further includes a protective member (not shown in the figures), and the protective member is installed on a side of the explosion-proof airbag 37 close to the tire 200 .

[0065] Therefore, the provision of the protective member can prevent the explosion-proof airbag 37 from being scratched or punctured by sharp objects after deployment, and avoid the explosion-proof airbag 37 from leaking after deployment, so that the explosion-proof airbag 37 can further achieve the anti-puncture effect.

[0066] In some embodiments, Figure 4 and Figure 7 As shown, the inflatable airbag 31 also includes a plurality of third connecting members 315, and the plurality of third connecting members 315 are spaced apart on a side of the inflatable airbag 31 close to the explosion-proof airbag 37. The explosion-proof airbag 37 also includes a plurality of fourth connecting members 377, and the plurality of fourth connecting members 377 are spaced apart on a side of the explosion-proof airbag 37 close to the inflatable airbag 31, so as to connect the plurality of third connecting members 315 correspondingly, and thus connect the inflatable airbag 31 and the explosion-proof airbag 37.

[0067] Thus, the inflatable airbag 31 and the explosion-proof airbag 37 are combined into one, which is convenient for the installation of the airbag device 3, and the airbag device 3 can be used in the case of a tire blowout of the tire 200, and can also be used in the case of a tire leak or deflation, thereby improving travel safety.

[0068] It can be understood that the plurality of third connecting members 315 and the plurality of fourth connecting members 377 can be connected by felt or adhesive, which is not limited here.

[0069] Please also read Fig. 9 , Fig. 9 FIG. 1 is a side view of a partial structure of the airbag device 3 in the embodiment of the present application. In some embodiments, as Figure 6 and Fig. 9 As shown, the airbag device 3 also includes a protective layer 36, which is installed around the inflatable airbag 31 and the mounting groove 11. A plurality of first connecting members 314 are arranged on a side of the inflatable airbag 31 close to the protective layer 36, and a side of the protective layer 36 away from the mounting groove 11 is connected to the plurality of first connecting members 314 to connect the protective layer 36 and the inflatable airbag 31.

[0070] Thus, the protective layer 36 is installed in the installation groove 11, and the inflatable airbag 31 is installed on the protective layer 36 through the multiple first connecting members 314. The provision of the protective layer 36 can prevent the inflatable airbag 31 from being scratched, thereby preventing the inflatable airbag 31 from leaking.

[0071] In some embodiments, the protective layer 36 is a protective cloth, which is inlaid and combined with a fixing steel wire, and is fixed in the mounting groove 11 by a fixing steel wire, a steel cable, etc., and is in direct contact with the mounting groove 11, wherein the fixing steel wire tightens the protective cloth so that it has no relative movement with the rim 1, so as to avoid friction between the protective cloth and the rim 1 and cause position displacement.

[0072] In some embodiments, a plurality of second connecting members (not shown in the figure) are provided on the side of the inflation hose 312 close to the protective layer 36 , and the plurality of second connecting members are connected to the side of the protective layer 36 away from the mounting groove 11 to connect the protective layer 36 and the inflation hose 312 .

[0073] Thus, the inflation hose 312 is connected to the protective layer 36 through the plurality of second connectors to fix the inflation hose 312 on the protective layer 36 , thereby preventing the inflation hose 312 from moving during the driving of the automobile 100 , thereby improving the inflation stability of the inflatable airbag 31 .

[0074] It is understandable that the first connecting member 314 and the second connecting member can be but are not limited to snaps, glue, etc., as long as they can achieve a fixed connection, and no limitation is made here.

[0075] In some embodiments, a gas generating device is provided in the explosion-proof airbag 37, which is used to generate gas to deploy the explosion-proof airbag 37 when the tire 200 bursts. The airbag device 3 also includes an insulation layer (not shown in the figure), which is arranged on the side of the protective layer 36 away from the rim 1, and the generator 375 is placed in the insulation layer.

[0076] Thus, the heat insulation layer isolates the heat generated when the gas generating device is in operation to protect the generator 375, improve the accuracy of the generator 375 in detecting tire pressure, and enable the controller 33 to better control the deployment or non-deployment of the explosion-proof airbag 37.

[0077] When controlling the explosion-proof airbag 37 to deploy, the controller 33 needs to control the gas generating device to generate gas so as to deploy the explosion-proof airbag 37 .

[0078] In some embodiments, the thermal insulation layer is a thermal insulation cover, and the generator 375 is located inside the thermal insulation cover.

[0079] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application; in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
