Description

Technical Field

[0001] The present invention relates to a tire valve, in particular to a tire valve and a wheel with the tire valve. Background Art

[0002] Valve stems offer excellent sealing properties, preventing tire leaks. They are used on various wheels to facilitate filling tires with air or deflation to adjust tire pressure. With the increasing popularity of vacuum tires, valve stems and tires are now independent of each other, making it easier for car owners to replace tires and valve stems separately.

[0003] An existing wheel 1000P includes a hub 100P, a tire 200P, and a valve 300P, wherein the wheel 1000P has an assembly through-hole 1001P and an air cavity 1002P connected to the assembly through-hole 1001P. The valve 300P mainly includes a valve core 310P and a sealing body 320P, wherein the sealing body 320P is arranged at the air outlet end of the valve core 310P. The tire 200P is detachably mounted on the outer wall of the hub 100P, and the air cavity 1002P is formed between the outer wall of the hub 100P and the tire 200P. The assembly through-hole 1001P passes through the inner and outer walls of the hub 100P. Figure 1B During the installation of the wheel 1000P, the wheel hub 100P and the tire 200P need to be separated with the aid of a tool to form an opening 1003P between the wheel hub 100P and the tire 200P. The air valve 300P is inserted into the air cavity 1002 through the opening 1003P. Furthermore, the air valve 300P passes through the outer wall and the inner wall of the wheel hub 100P in sequence before being retained in the assembly through-hole 1001P of the wheel hub 100P.

[0004] To ensure the sealing performance of the valve stem 300P, the cross-section of the sealing body 320P of the common valve stem 300P gradually increases from the air inlet end of the valve core 310P to the air outlet end of the valve core 310P. The portion of the sealing body 320P with a smaller cross-sectional dimension than the assembly through-hole 1001P passes through the assembly through-hole 1001P from the air cavity 1002P and is retained inside the inner wall of the wheel hub 100P. The portion of the sealing body 320P with a larger cross-sectional dimension than the assembly through-hole 1001P is retained outside the outer wall of the wheel hub 100P, sealing the assembly through-hole 1001P by blocking it. The tire 200P wraps around the outer wall of the wheel hub 100P, and the valve core 310P is used to fill the air cavity 1002P of the wheel 1000P with gas, preventing gas leakage through the sealing body 320P. That is to say, the existing valve stem 300P is installed from the inside of the tire 200P to the outside of the tire 200P. In actual use, it causes a lot of troubles to the car owner.

[0005] Specifically, refer to Figure 1A and Figure 1B The existing air valve 300P is installed in the assembly hole 1001P of the wheel hub 100P from the air cavity 1002P of the wheel 1000P. If the air valve 300P malfunctions during use, the owner cannot separate the air valve 300P from the wheel hub 100P from the outside of the wheel 1000P. The owner must first use a tool to separate the wheel hub 100P from the tire 200P, forming the opening 1003P between the wheel hub 100P and the tire 200P. The owner can then pull the damaged air valve 300P out from the outside of the wheel hub 100P and remove it from the opening 1003P. Furthermore, after inserting the new valve stem 300P into the air cavity 1002P from the opening 1003P, it is then inserted into the assembly through-hole 1001P of the wheel hub 100P from the outside of the wheel hub 100P, and finally the tire 200P is kept covering the outer wall of the wheel hub 100P. This operation is not only complicated but also quite difficult, usually requiring professionals using specialized repair tools to complete. Car owners who are driving outside have no choice but to replace the entire wheel 1000P to keep their vehicle running normally, and the wheel 1000P with a damaged valve stem 300P can only be transported to a repair shop for replacement, which increases the repair costs for the car owner.

[0066] Reference Figures 2 to 4B A wheel 1000 with an air valve and an air valve 100 according to a preferred embodiment of the present invention will be described below. The wheel 1000 includes the air valve 100, a hub 200, and a tire 300. The tire 300 covers the outer wall of the hub 200, and the air valve 100 is installed on the hub 200 from the outside to inflate or deflate the tire 300. In other words, during the installation of the air valve 100 on the hub 200, there is no need to disassemble the hub 200 and the tire 300, which simplifies the installation method of the air valve 100 and reduces the professional skills required of the operator.

[0067] Specifically, the wheel 1000 has a gas chamber 1001, and the hub 200 has a through-hole 201, wherein the through-hole 201 extends through the inner and outer walls of the hub 200. The gas chamber 1001 is formed between the outer wall of the tire 200 and the tire 300. The valve 100 is installed in the through-hole 201 of the hub 200 from the inner wall of the hub 200. The valve 100 is stably held in the through-hole 201 of the hub 200 and seals the through-hole 201 of the hub 200, preventing gas leakage from the gas chamber 1001 of the wheel 1000.

[0068] In this specific embodiment of the air valve 100 of the present invention, the air valve 100 includes a valve body 110 and an assembly component 120, wherein the valve body 110 has an air inlet 1101 and an air outlet 1102 that allows communication with the air inlet 1101. The assembly component 120 is mounted on the valve body 110, and the assembly component 120 is close to the air outlet 1102 of the valve body 110. The valve body 110 passes through the assembly through-hole 201 of the wheel hub 200 with the air outlet 1102 facing the assembly through-hole 201. The valve body 110 and the assembly component 120 enter the gas chamber 1001 from the assembly through-hole 201 of the wheel hub 200. The gas outlet 1102 of the valve body 110 is connected to the gas chamber 1001, and gas is filled into the gas chamber 1001 through the valve body 110. The assembly component 120 is retained in the assembly through-hole 201 of the wheel hub 200, and the assembly through-hole 201 is sealed by the assembly component 120, thereby preventing gas in the gas chamber 1001 from leaking through the assembly through-hole 201.

[0069] Specifically, in a preferred embodiment of the present invention, the valve body 110 of the air valve 100 includes a valve body 111 and a blocking portion 112, wherein the blocking portion 112 extends outward from the outer surface of the valve body 111 and is retained at one end of the valve body 111, and is close to the air outlet 1102. The assembly component 120 includes a stopper 121 and a fastener 122, wherein the stopper 121 and the fastener 122 are mounted on the valve body 111, and the stopper 121 is retained between the fastener 122 and the blocking portion 112 of the valve body 110. In a specific example of the present invention, the blocking portion 112 and the valve body 111 are an integrated structure, for example, but not limited to, the blocking portion 112 and the valve body 111 are integrally formed or the blocking portion 112 is welded to the valve body 111. In another specific example of the present invention, the blocking portion 112 and the valve body 111 are separate structures, and the blocking portion 112 is detachably mounted on the valve body 111, for example, but not limited to, the blocking portion 112 is mounted on the valve body 111 by threaded connection.

[0070] The limiting member 121 of the assembly component 120 further includes a first limiting member 1211 and a second limiting member 1212, wherein the first limiting member 1211 and the second limiting member 1212 are installed on the valve body 111, the first limiting member 1211 is retained between the second limiting member 1212 and the blocking portion 112 of the valve body 110, and the second limiting member 1212 is retained between the first limiting member 1211 and the fastener 122. Preferably, the first limiting member 1211 and the second limiting member 1212 are both provided with a mounting through hole 1210 adapted to the cross-sectional size of the valve body 111, and the first limiting member 1211 and the second limiting member 1212 of the limiting member 121 are sleeved on the valve body 111, that is, the valve body 111 is retained in the mounting through holes 1210 of the first limiting member 1211 and the second limiting member 1212 of the limiting member 121.

[0071] Preferably, the blocking portion 112 of the valve body 110 is attached to the first limiting member 1211, and the blocking member 112 closes the mounting hole 1210 by covering the mounting hole 1210 of the first limiting member 1211, thereby preventing gas from leaking from the mounting hole 1210, thereby ensuring the air tightness of the valve 100.

[0072] Preferably, the valve body 111 has an external thread on its outer surface, and the fastener 122 has an internal thread that mates with the external thread. The fastener 122 is mounted on the valve body 111 with the internal and external threads interconnected, and is retained on one side of the second stopper 1212. Preferably, the external thread extends from the air inlet 1101 of the valve body 110 to the other end of the valve body 111. When the fastener 122 moves along the extension direction of the external thread toward the blocking portion 112, it presses against the stopper 121. For example, but not limited to, the fastener 122 is implemented as a nut. Those skilled in the art should understand that the specific connection between the valve body 111 and the fastener 122 is merely exemplary and does not limit the content and scope of the valve 100 and the wheel 1000 of the present invention.

[0073] The cross-sectional dimensions of the blocking portion 112 of the valve body 110 and the first limiting member 1211 of the limiting member 121 of the assembly component 120 are smaller than the dimensions of the assembly through hole 201 of the wheel hub 200. The blocking portion 112 of the valve body 110 and the first limiting member 121 of the limiting member 121 pass through the assembly through hole 201 of the wheel hub 200 and enter the gas chamber 1001 of the wheel 1000. The cross-sectional size of the second limiting member 1212 of the limiting member 121 is larger than the size of the assembly through hole 201 of the wheel hub 200. When the first limiting member 121 and the end of the valve body 110 enter the gas chamber 1001, the second limiting member 1212 of the limiting member 121 fits against the inner wall of the wheel hub 200 and covers the assembly through hole 201 of the wheel hub 200, which helps to prevent the valve 100 from falling into the gas chamber 1001 from the assembly through hole 201 during installation.

[0074] Furthermore, the first limiting member 1211 of the limiting member 121 is retained in the assembly hole 201 of the wheel hub 200 after expansion, so as to prevent the valve stem 100 and the wheel hub 200 from separating, and at the same time helps the valve stem 100 to seal the assembly hole 201 of the wheel hub 200 to prevent the wheel 1000 from leaking air.

[0075] According to one embodiment of the present invention, the first stopper 1211 of the stopper 121 is elastic. When the second stopper 1212 of the stopper 121 is attached to the wheel hub 200, the fastener 122 is rotated, causing the fastener 122 to move toward the stopper 121 and compress the second stopper 1212 of the stopper 121. The blocking member 112 of the valve body 110 compresses the first stopper 1211 of the stopper 121, causing the first stopper 1211 to deform perpendicular to the extension of the valve body 110, thereby increasing the cross-sectional area of ​​the first stopper 121. When the cross-sectional dimension of the first stopper 1211 is greater than the dimension of the assembly hole 201 of the wheel hub 200, the valve 100 is stably retained in the assembly hole 201 of the wheel hub 200. Furthermore, the first stopper 1211 of the stopper 121 deforms to fit against the outer wall of the wheel hub 200, thereby sealing the assembly hole 201 of the wheel hub 200 and the gas chamber 1001 of the wheel 1000, thereby preventing air leakage from the wheel 1000. In other words, the deformation of the first stopper 1211 prevents the valve body 110 from leaving the assembly hole 201 of the wheel hub 200 and seals the assembly hole 201.

[0076] In this specific example of the valve 100 described in the present invention, the second limiting member 121 of the limiting member 121 is also elastic. The second limiting member 1212 is deformed after being squeezed by the fastener 122, and seals the assembly hole 201 of the wheel hub 200, further enhancing the sealing effect of the valve 100.

[0077] Preferably, the second stopper 1212 of the stopper 121 is integrally formed with the first stopper 1211. Optionally, the first stopper 1211 and the second stopper 1212 of the stopper 121 are independent of each other. Preferably, the first stopper 1211 and the second stopper 1212 of the stopper 121 are made of the same material. For example, but not limited to, the first stopper 1211 and the second stopper 1212 are made of rubber through an injection molding process. Optionally, the first stopper 1211 and the second stopper 1212 are made of different materials. For example, the first stopper 1211 is made of rubber, and the second stopper 1212 is made of stainless steel or other materials. Those skilled in the art should understand that the specific embodiments of the first stopper 1211 and the second stopper 1212 of the stopper 121 are merely illustrative and are not intended to limit the content and scope of the valve 100 of the present invention.

[0078] According to another preferred embodiment of the present invention, the assembly component 120 of the valve 100 further includes an auxiliary member 123, wherein the auxiliary member 123 is mounted on the valve body 111 of the valve body 110, and the auxiliary member 123 is held between the fastener 122 and the second stopper 1212 of the stopper 121. When the fastener 122 moves toward the blocking member 112 of the valve body 110, the auxiliary member 123 is pressed, and the auxiliary member 123 presses the second stopper 1212 of the stopper 121. Preferably, the size of the auxiliary part 123 is greater than or equal to the size of the second limiting part 1212 of the limiting part 121, and the auxiliary part 123 covers the upper surface of the second limiting part 1212, so that after the fastener 122 applies force to the auxiliary part 123, the auxiliary part 123 can evenly apply force to the second limiting part 1212 of the limiting part 121, so as to facilitate the second limiting part 1212 of the limiting part 121 to be uniformly stressed and deformed.

[0079] The air valve 100 further includes a closing cover 130 , wherein the closing cover 130 is detachably mounted on the air valve body 110 of the air valve body 110 and can close the air inlet 1101 of the air valve body 110 , thereby ensuring the air tightness of the air valve 100 .

[0080] It is worth mentioning that in the attached Figures 2 to 4B In the illustrated embodiment of the valve 100, the valve 100 can be removed from the outside of the wheel hub 200 to facilitate replacement of the valve 100. Specifically, during disassembly of the valve 100, the fastener 122 and the auxiliary member 123 are sequentially removed from the valve body 110. The squeezing force exerted on the first and second limiting members 1211, 1212 of the limiting member 121 is released, and the valve body 110 is pulled outward to separate the valve 100 from the wheel hub 200. That is to say, during the process of replacing the valve body 110, the operator can remove the valve 100 from the outside of the wheel hub 200, or install the valve 100 on the wheel hub 200 from the outside of the wheel hub 200, without separating the wheel hub 200 and the tire 300. The operation is simple and the requirements for professional ability are low. The car owner can replace the valve body 110 by himself, which is conducive to reducing repair costs.

[0081] Attachment Figures 2 to 4BThe blocking portion 112 of the valve body 110 of the valve 100 shown is cylindrical, and the size of the upper surface of the blocking portion 122 is larger than the size of the mounting through hole 1210 of the first limiting member 1211 of the limiting member 121. The blocking portion 112 is maintained on one side of the first limiting member 1211 in a manner that the upper surface is in contact with the surface of the first limiting member 1211 of the limiting member 121. In the process of the fastener 122 squeezing the second limiting member 1212 of the limiting member 121, the blocking portion 112 squeezes the first limiting member 1211 in a manner that is in contact with the first limiting member 1211 of the limiting member 121, and causes the first limiting member 1211 to deform.

[0082] Instructions attached Figures 5 to 6B The valve 100 shown is Figures 2 to 4B The difference of the valve 100 shown is that the Figures 5 to 6B The blocking portion 112 of the valve body 110 of the illustrated air valve 100 is truncated in a cone shape. Specifically, the blocking portion 112 of the valve body 110 has a first assembly end 1121 and a second assembly end 1122 opposite the first assembly end 1121. The second assembly end 1122 of the blocking portion 112 is located near the air outlet 1102. The cross-sectional area of ​​the blocking portion 112 gradually increases from the first assembly end 1121 to the second assembly end 1122. The cross-sectional area 1121 of the first assembly end 1121 of the blocking portion 112 is smaller than the size of the mounting hole 1210 of the first stopper 1211 of the stopper 121, while the cross-sectional area 1122 of the second assembly end 1122 of the blocking portion 112 is larger than the size of the mounting hole 1210 of the first stopper 1211 of the stopper 121. The first assembly end 1121 of the blocking portion 112 is retained in the mounting through hole 1210 of the first limiting member 1211 of the limiting member 121 , and the second assembly end 1122 of the blocking portion 112 is retained on one side of the first limiting member 1211 of the limiting member 121 .

[0083] Reference Figures 5 to 6BAs the fastener 122 compresses the second stopper 1212 of the stopper 121, the first assembly end 1121 of the blocking portion 112 moves within the mounting hole 1210 of the first stopper 1211 of the stopper 121, gradually approaching the first stopper 1211. The cross-section of the portion of the blocking portion 112 that enters the mounting hole 1210 of the first stopper 1211 gradually increases, causing the first stopper 1211 of the stopper 121 to deform and expand. When the cross-section of the first stopper 1211 of the stopper 121 is larger than the mounting hole 201 of the wheel hub 200, the valve 100 is secured to the wheel hub 200. Furthermore, the first limiting member 1211 closes the assembly through hole 201 of the wheel hub 200 to prevent gas leakage in the gas chamber 1001 of the wheel 1000 .

[0084] Instructions attached Figures 7 to 8B The valve 100 shown is Figures 2 to 4B The difference of the valve 100 shown is that Figures 7 to 8B The first limiting member 1211 of the limiting member 121 of the valve 100 shown includes a retaining portion 12111 and a limiting portion 12112, wherein the limiting portion 12112 extends outward from the retaining portion 12111 as a whole, and the retaining portion 12111 is located between the second limiting member 1212 and the limiting portion 12112, and the limiting portion 12112 is retained between the retaining portion 12111 and the blocking portion 112 of the valve body 110. The limiting portion 12112 has a first limiting end 121121 and a second limiting end 121122 opposite to the first limiting end 121121. The first limiting end 121121 is connected to the retaining portion 12111. The cross-sectional dimension of the limiting portion 12112 gradually decreases from the first limiting end 121121 to the second limiting end 121122. The cross-sectional dimension of the second limiting end 121122 is smaller than the dimension of the assembly through-hole 201 of the wheel hub 200. The cross-sectional dimension of the first limiting end 121122 of the limiting member 1211 is larger than the dimension of the assembly through-hole 201 of the wheel hub 200, and the cross-sectional dimension of the retaining portion 1211 is smaller than the dimension of the assembly through-hole 201 of the wheel hub 200.

[0085] Reference Figures 8A to 8BWhen the limiting portion 12112 of the first limiting member 1211 of the limiting member 121 passes through the assembly through-hole 201 of the wheel hub 200, it pushes the valve 300 to move toward the gas chamber 1001 of the wheel 1000. The wheel hub 200 presses the limiting portion 12112 of the first limiting member 1211, causing the limiting portion 12112 of the limiting member 1211 to deform. The cross-sectional dimension of the deformed limiting portion 12112 can be smaller than or equal to the assembly through-hole 201 of the wheel hub 200, thereby allowing the deformed limiting portion 12112 to pass through the assembly through-hole 201. After the first limiting end 121121 of the limiting portion 12112 of the first limiting member 121 passes through the assembly hole 201 of the wheel hub 200, the squeezing force of the wheel hub 200 on the limiting portion 12112 of the first limiting member 1211 disappears, and the limiting portion 12112 returns to its original state. The limiting portion 1211 is retained within the gas chamber 1001 of the wheel 1000, the retaining portion 12111 of the first limiting member 1211 is retained in the assembly hole 201 of the wheel hub 200, and the inner and outer walls of the wheel hub 200 are retained between the limiting portion 1211 of the first limiting member 121 of the limiting member 120 and the second limiting member 121. In this way, the valve 100 is fixed to the wheel hub 200.

[0086] Preferably, the limiting portion 12112 of the first limiting portion 121 is a hollow structure so that it can be quickly deformed after being squeezed by the wheel hub 200, so that the valve 100 can be easily installed on the wheel hub 200. Optionally, the limiting portion 12112 of the first limiting portion 121 is a solid structure.

[0087] Preferably, the distance between the inner wall and the outer wall of the wheel hub 200 is consistent with the distance between the limiting portion 1211 of the first limiting member 121 and the second limiting member 121, so that after the first limiting end 12111 of the limiting portion 1211 of the first limiting member 121 passes through the assembly through-hole 201 of the wheel hub 200, the limiting portion 1211 of the first limiting member 121 and the second limiting member 122 are tightly attached to the outer wall and the inner wall of the wheel hub 200, thereby sealing the assembly through-hole 201 of the wheel hub 200. Preferably, the fastener 122 is further tightened, and the assembly through-hole 201 of the wheel hub 200 is further sealed by deforming the second limiting member 122 and the first limiting member 121.

[0088] Instructions attached Figures 9 to 10B The valve 100 shown is Figures 2 to 4BThe difference of the valve 100 shown is that the Figures 9 to 10B The valve 100 shown can be retained in the assembly through hole 201 of the wheel hub 200 without being deformed.

[0089] Specifically, the limiting portion 12112 of the first limiting member 1211 of the limiting member 121 is strip-shaped, meaning that the length of the limiting portion 12112 is greater than its width. More specifically, the length of the limiting portion 12112 is greater than the diameter of the assembly hole 201 of the wheel hub 200, and the width of the limiting portion 12112 is less than the diameter of the assembly hole 201 of the wheel hub 200. The valve 100 passes through the assembly hole 201 of the wheel hub 200 via the limiting portion 12112 of the first limiting member 1211 at an oblique angle to the inner wall of the wheel hub 200. After the limiting portion 12112 completely enters the gas chamber 1001 , the valve 100 is adjusted so that the limiting portion 12112 blocks the assembly through hole 201 of the wheel hub 200 , and the valve 100 is stably held in the assembly through hole 201 of the wheel hub 200 .

[0090] Furthermore, the fastener 122 is tightened, and the second limiting member 122 and the first limiting member 121 are deformed to further seal the assembly through hole 201 of the wheel hub 200 .

[0091] It is worth mentioning that, in this specific embodiment, the limiting portion 12112 of the first limiting member 1211 of the valve 100 can also pass through the assembly through hole 201 by deforming.
