Description

Technical Field

[0001] The utility model relates to the field of tires, in particular to an internal pressure balanced tire. Background Art

[0002] As an important part of a car, the safety of the tire is of vital importance. During the driving process, the tire pressure will be affected by the external environment and may be too high or too low, which may cause certain safety hazards.

[0003] At present, the tire pressure adjustment of most models on the market requires going to a car repair shop to find a technician to adjust it or using the on-board charging drive mechanism to inflate it by yourself. Both solutions require going to a fixed place and adjusting it at a fixed frequency, which is not convenient for daily maintenance. At the same time, during long-distance driving, due to changes in altitude, temperature, vehicle speed, etc., the adjusted tire pressure will no longer be appropriate, and the tire pressure will still be too high or too low, posing certain safety hazards. Utility Model Content

[0004] The utility model aims to solve the problem of potential safety hazards caused by excessively high or low tire pressure. The utility model provides an internal pressure balanced tire that can achieve self-adjustment of tire pressure and avoid potential safety hazards.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses an internal pressure balanced tire, which is characterized by comprising:

[0006] A tire body, wherein an inner tube is arranged in the tire body, a first interval and a second interval are spaced axially between the inner tube and the tire body, a tread of the tire body is provided with a plurality of grooves extending in a circumferential direction, the plurality of grooves are spaced apart in a first direction, and the first direction intersects the circumferential direction;

[0007] Two air bags, the two air bags are respectively located in the first interval and the second interval, each of the air bags extends along the circumferential direction, and a one-way valve is provided between each of the air bags and the inner tube, and the one-way valve is used to transport the gas in the air bag to the inner tube;

[0008] A conveying bag corresponding to the airbags one by one, the conveying bag is arranged on the inner wall of the tire crown along the radial direction, and the conveying bag is connected to the corresponding airbag;

[0009] A constant pressure mechanism, a part of which is located in the groove, and the constant pressure mechanism is connected to each of the conveying bags.

[0010] With the above technical solution, when the inner tube tire pressure is too high, the inner tube will squeeze the two airbags located in the first interval and the second interval. The airbags are connected to the delivery bag. Under the extrusion of the inner tube, the air inside the airbags is delivered into the delivery bag. The delivery bag is connected to the constant pressure mechanism, and the gas in the delivery bag is delivered to a part of the constant pressure mechanism located in the groove. When the gas reaches this part of the constant pressure mechanism, this part of the constant pressure mechanism will expand and protrude from the groove to contact the ground, increasing the grip between the tire and the ground. When the tire pressure of the inner tube returns to normal, this part of the constant pressure mechanism returns to its original state and is located in the groove, ensuring normal tire pressure of the inner tube. When the inner tube tire pressure is too low, at this time, the pressure inside the inner tube is less than the pressure of the two airbags located in the first interval and the second interval. The gas in the two airbags is delivered into the inner tube through the one-way valve to make the inner tube tire pressure normal.

[0011] That is to say, for the inner pressure balance tire provided by the embodiment of the present application, when the inner tube tire pressure is too high or too low, it can ensure the stability of the tire pressure through the cooperation of the above-mentioned airbags, delivery bag and constant pressure mechanism, preventing potential safety hazards caused by too high or too low tire pressure.

[0012] According to another specific embodiment of the present invention, the embodiment of the present invention discloses an inner pressure balance tire. The constant pressure mechanism includes a delivery pipe and an inflatable bag corresponding to each groove. The delivery pipe is located inside the tread and extends along the axial direction. The inflatable bag is located in the corresponding groove, and each inflatable bag extends along the circumferential direction. One end of the delivery pipe is connected to the delivery bag, and the other end is connected to each inflatable bag.

[0013] With the above technical solution, when the inner tube tire pressure is too high, the inner tube will squeeze the two airbags located in the first interval and the second interval. The airbags are connected to the delivery bag. Under the extrusion of the inner tube, the air inside the airbags is delivered into the delivery bag. One end of the delivery bag is connected to the delivery pipe, and the gas in the delivery bag is delivered to the delivery pipe. The other end of the delivery pipe is connected to the inflatable bag, so as to be delivered to the inflatable bag. The inflatable bag is located in the groove. When the gas reaches the inflatable bag, the inflatable bag will expand and protrude from the groove to contact the ground. When the tire pressure of the inner tube returns to normal, the inflatable bag returns to its original state and is located in the groove, ensuring normal tire pressure of the inner tube while increasing the grip between the tire body and the ground, preventing potential safety hazards caused by too high tire pressure.

[0014] According to another specific embodiment of the present invention, the embodiment of the present invention discloses an inner pressure balance tire. The other end of the delivery pipe is connected with a plurality of conduits corresponding to the inflatable bags one by one. One end of the conduit is located inside the tread and is connected to the other end of the delivery pipe, and the other end of the conduit passes through the bottom wall of the groove and is connected to the corresponding inflatable bag.

[0015] With the above technical solution, the delivery bag is connected to the inflatable bag through a conduit. When the inner tube tire pressure is too high, the gas in the airbag can be sequentially delivered to the delivery bag and the delivery pipe under the extrusion of the inner tube, and then delivered to each inflatable bag through the conduit. When the gas reaches the inflatable bag, the inflatable bag will expand and protrude from the groove to contact the ground. When the tire pressure of the inner tube returns to normal, the inflatable bag returns to its original state and is located in the groove. While ensuring the normal tire pressure of the inner tube, the grip between the tire body and the ground is increased, preventing potential safety hazards caused by excessive tire pressure.

[0016] According to another specific embodiment of the present invention, an inner pressure balanced tire is disclosed in an embodiment of the present invention. A tread rubber is provided on a side of the inflatable bag away from the delivery pipe, and the tread rubber is used to contact the ground.

[0017] With the above technical solution, by providing the tread rubber, when the inner tube tire pressure is too high and the inner tube squeezes the airbag to deliver the gas inside to the inflatable bag, when the inflatable bag protrudes from the groove, the tread rubber on the side of the inflatable bag away from the delivery pipe will preferentially contact and rub against the ground, thereby protecting the inflatable bag and extending its service life.

[0018] According to another specific embodiment of the present invention, an inner pressure balanced tire is disclosed in an embodiment of the present invention. A first inflation valve corresponding to the airbag is provided on a tire side of the tire body, and the first inflation valve penetrates through the tire body to be connected to the corresponding airbag.

[0019] With the above technical solution, air can be pumped into the airbag through the first inflation valve for reserve. When the inner tube tire pressure is too low, there is enough gas in the airbag to be delivered to the inner tube to ensure the normal and stable air pressure.

[0020] According to another specific embodiment of the present invention, an inner pressure balanced tire is disclosed in an embodiment of the present invention. A second inflation valve is provided on a tire side of the tire body, and the second inflation valve penetrates through the tire body to be connected to the inner tube.

[0022] According to another specific embodiment of the present invention, an inner pressure balanced tire is disclosed in an embodiment of the present invention. An anti-slip layer is provided on a tire shoulder of the tire body.

[0023] With the above technical solution, the anti-slip layer can increase the friction between the tire body and the ground, prevent the inner pressure balanced tire from slipping, and ensure the stability and safety of driving.

[0024] According to another specific embodiment of the present utility model, an internal pressure balanced tire is disclosed in the embodiment of the present utility model. The anti-slip layer is made of synthetic rubber, and a plurality of tread grooves are formed on the surface of the anti-slip layer. The plurality of tread grooves are arranged at intervals along the circumferential direction.

[0025] Adopting the above technical solution, the synthetic rubber material has good properties such as being not easily aged, high elasticity, wear resistance, etc. Using the synthetic rubber material can improve the service life and safety of the internal pressure balanced tire. At the same time, the tread grooves can increase the friction between the tire body and the ground, prevent the internal pressure balanced tire from slipping, and ensure the stability and safety of driving.

[0026] According to another specific embodiment of the present utility model, an internal pressure balanced tire is disclosed in the embodiment of the present utility model. A drainage strip is formed between each adjacent groove. The drainage strip is made of synthetic rubber, and a plurality of tread chamfers are formed on the outer surface of the drainage strip.

[0041] Reference Figure 1 、 Figure 1a and Figure 2 and Figure 1 shown in the B direction), and is spaced apart from the tire body 100 in the axial direction (i.e., Figure 1 shown in the X direction).

[0042] Exemplarily, there are a first interval 102 and a second interval 103 spaced apart in the axial direction between the inner tube 101 and the tire body 100. For the convenience of description, in the axial direction, the one on the left is the first interval 102, and the one on the right is the second interval 103. The tread 104 of the tire body 100 is provided with five grooves 500 extending in the circumferential direction, but not limited thereto, and can also be three, six, eight, ten, etc. The five grooves 500 are spaced apart in the first direction (i.e., Figure 1 shown in the C direction), and the first direction (i.e., Figure 1 shown in the C direction) intersects with the circumferential direction (i.e., Figure 1 shown in the B direction).

[0043] Exemplarily, the two air bags 200 are respectively located in the first interval 102 and the second interval 103, that is, in the axial direction (i.e., Figure 1 shown in the X direction), and the two air bags 200 are respectively located on the left and right sides of the inner tube 101. Each air bag 200 extends in the circumferential direction, and a one-way valve 201 is provided between each air bag 200 and the inner tube 101 on the side close to the inner tube 101. Specifically, a one-way valve 201 is provided on the side of each air bag 200 close to the inner tube 101. The one-way valve 201 is connected to one side of the inner tube 101, and the one-way valve 201 is used to convey the gas in the two air bags 200 to the inner tube 101.

[0044] Exemplarily, two conveying bags 300 respectively correspond to two air bags 200 one by one. Along the radial direction (i.e., Figure 1 the Y direction shown), each conveying bag 300 is arranged on the inner wall of the tread 105. The conveying bag 300 is communicated with the corresponding air bag 200. A part of the constant pressure mechanism 400 is located in the groove 500, and the constant pressure mechanism 400 is communicated with each conveying bag 300.

[0045] Exemplarily, referring to Figure 3a and Figure 3b and in combination with Figure 1 , when the air pressure in the inner tube 101 is too high, the inner tube 101 will squeeze the two air bags 200 located in the first interval 102 and the second interval 103. The air bags 200 are communicated with the conveying bags 300. Under the extrusion of the inner tube 101, the air inside the air bags 200 is conveyed into the conveying bags 300. The conveying bags 300 are communicated with the constant pressure mechanism 400, and the gas in the conveying bags 300 is conveyed to a part of the constant pressure mechanism 400 located in the groove 500. When the gas reaches this part of the constant pressure mechanism 400, this part of the constant pressure mechanism 400 will expand and protrude from the groove 500 to contact the ground (i.e., from the state shown in Figure 3a converted to the state shown in Figure 3b ), increasing the grip force with the ground. When the air pressure in the inner tube 101 returns to normal, this part of the constant pressure mechanism 400 returns to its original state and is located in the groove 500 (i.e., from the state shown in Figure 3b converted to the state shown in Figure 3a ).

[0046] Exemplarily, referring to Figure 3a and Figure 3c and in combination with Figure 1 , when the air pressure in the inner tube 101 is too low (i.e., when in the state shown in Figure 3c ), at this time, the pressure inside the inner tube 101 is less than the pressure of the two air bags 200 located in the first interval 102 and the second interval 103. The gas in the two air bags 200 is conveyed into the inner tube 101 through the one-way valve 201 to make the air pressure in the inner tube 101 normal (i.e., from the state shown in Figure 3c converted to the state shown in Figure 3a ), thereby reducing the adhesion between the tire body and the ground and reducing the rolling resistance of the inner pressure balanced tire.

[0047] That is to say, when the air pressure in the inner tube 101 of the inner pressure balanced tire provided by the embodiment of the present application is too high or too low, the above-mentioned air bags 200, conveying bags 300 and constant pressure mechanism 400 can be used to ensure the stability of the air pressure and prevent potential safety hazards caused by too high or too low air pressure.

[0048] Exemplarily, referring to Figure 1a , Figure 2 andFigure 3a The constant pressure mechanism 400 includes a delivery pipe 401 and five inflatable bags 402 corresponding to the five grooves 500 one by one. The delivery pipe 401 is located inside the tread crown 105 and extends axially (i.e., in the Figure 2 X direction shown), and the inflatable bags 402 are located in the grooves 500 corresponding to them. Each inflatable bag 402 extends circumferentially (i.e., in the Figure 2 B direction shown). One end of the delivery pipe 401 is connected to the delivery bag 300, and the other end is connected to each inflatable bag 402.

[0049] Exemplarily, referring to Figure 3a and Figure 3b and combining with Figure 1 and Figure 1a , when the tire pressure of the inner tube 101 is too high, the inner tube 101 will squeeze the two air bags 200 located in the first interval 102 and the second interval 103. The air bags 200 are connected to the delivery bag 300. Under the extrusion of the inner tube 101, the air inside the air bags 200 is delivered into the delivery bag 300. One end of the delivery bag 300 is connected to the delivery pipe 401, and the gas in the delivery bag 300 is delivered to the delivery pipe 401. The other end of the delivery pipe 401 is connected to the inflatable bag 402, so as to be delivered to the inflatable bag 402. The inflatable bag 402 is located in the groove 500. When the gas reaches the inflatable bag 402, the inflatable bag 402 will expand and protrude from the groove 500 to contact the ground (i.e., from the state shown in Figure 3a to the state shown in Figure 3b ), increasing the grip force with the ground and preventing potential safety hazards caused by too high tire pressure. When the tire pressure of the inner tube 101 returns to normal, the inflatable bag 402 returns to its original state and is located in the groove 500 (i.e., from the state shown in Figure 3b to the state shown in Figure 3a ).

[0050] Exemplarily, referring to Figure 1a , Figure 2 and Figure 3a , the delivery bag 300 is connected to its corresponding air bag 200 through a connecting pipe 301. The other end of the delivery pipe 401 is connected with five conduits 403 corresponding to the inflatable bags 402 one by one. One end of the conduit 403 is located in the tread crown 105 and is connected to the other end of the delivery pipe 401, and the other end passes through the bottom wall of the groove 500 and is connected to its corresponding inflatable bag 402.

[0051] Exemplarily, the delivery bag 300 is communicated with the inflatable bag 402 through the catheter 403 and the delivery pipe 401. When the tire pressure of the inner tube 101 is too high, the gas in the airbag 200 can be squeezed by the inner tube 101 and input into the delivery bag 300 through the connecting pipe 301, then input into the delivery pipe 401 through the delivery bag 300, and then transported to each inflatable bag 402 through the catheter 403. When the gas reaches the inflatable bag 402, the inflatable bag 402 will expand and protrude from the groove 500 to contact the ground, increasing the grip with the ground and preventing potential safety hazards caused by excessive tire pressure.

[0052] It should be noted that the number of the catheter 403 and the inflatable bag 402 is not limited in the embodiment of the present application, as long as the numbers of the two are the same and less than or equal to the number of the grooves 500.

[0053] Exemplarily, referring to Figures 3a to 3c , a tread rubber 404 is provided on the side of the inflatable bag 402 away from the delivery pipe 401, and the tread rubber 404 is used to contact the ground. When the tire pressure of the inner tube 101 is too high and the inner tube 101 squeezes the airbag 200 to transport the gas inside it to the inflatable bag 402, when the inflatable bag 402 protrudes from the groove 500, the tread rubber 404 on the side of the inflatable bag 402 away from the delivery pipe 401 will first contact and rub against the ground, thereby protecting the inflatable bag 402 and extending its service life.

[0054] Exemplarily, referring to Figure 4 and combining with Figure 1 , a first inflation valve 108 corresponding to the above-mentioned airbag 200 one by one is provided on the tire side 106 of the tire body 100, and the first inflation valve 108 penetrates the tire body 100 to be connected to its corresponding airbag 200.

[0055] That is to say, first inflation valves 108 are provided on both sides of the two airbags 200 close to the tire body 100, and each first inflation valve 108 penetrates the tire body 100. Through the first inflation valve 108, air can be pumped into the airbag 200 for storage. When the tire pressure of the inner tube 101 is too low, there is enough gas in the airbag 200 to be transported to the inner tube 101 to ensure the normal and stable air pressure.

[0056] Exemplarily, referring to Figure 4 and combining with Figure 1 , a second inflation valve 109 is provided on the tire side 106 of the tire body 100, and the second inflation valve 109 penetrates the tire body 100 to be connected to the inner tube 101. Through the second inflation valve 109, air can be pumped into the inner tube 101.
