Description

Technical Field

[0001] This application relates to the technical field of automotive tire safety devices, and more specifically, to a tire deflation valve. Background Art

[0002] A tire deflation valve is a device used to regulate and control the internal air pressure of a tire. It allows for rapid decompression or the release of some of the gas inside the tire when needed. The use of a tire deflation valve is of great significance for improving the adaptability and safety of vehicles in different terrains. Such a device can be used in many application scenarios, such as off-road, desert driving, or racing activities. In off-road driving, by quickly adjusting the tire pressure, the passability and maneuverability of the vehicle on different terrains can be significantly improved. In racing activities, the correct tire pressure is equally crucial for improving vehicle performance and ensuring driving safety. In addition, the tire deflation valve can also be applied to extreme weather and environments to ensure the stability and safety of the vehicle.

[0003] The design and functions of tire deflation valves are diverse, including manual operation and automatic adjustment types. Manually operated deflation valves require users to manually release the gas through specific tools or mechanisms. Such deflation valves are not only troublesome to operate but also unable to adjust with more subtle precision and cannot regulate the tire pressure to an appropriate level. Automatically adjusted deflation valves can automatically discharge gas according to the tire pressure or the usage conditions of the vehicle to keep the tire working within the optimal pressure range. However, such deflation valves usually rely mainly on electronic induction and control, which are not only costly but also prone to damage and do not have good economic efficiency. Summary of the Utility Model

[0004] To solve the above technical problems, this application is proposed. The advantage of this application is to provide a tire deflation valve that can not only control the regulation component to regulate a large deflation value but also generate a small displacement by driving the barrier member to rotate, corresponding to the scale value on the circumferential direction of the valve body outer wall, so as to regulate the deflation amount more subtly and precisely, convert the adjustable tire pressure change amount into a visual scale, and thus realize manual presetting of the deflation threshold. When the air pressure in the tire is too high, the gas pushes the valve core and overcomes the elastic force of the elastic member. At this time, the valve core disengages from the conical inner wall, and the gas in the tire is discharged through the deflation port, thereby realizing automatic pressure relief to ensure that the inside of the tire remains at or below the preset safety threshold. In addition, the gas can also be quickly discharged by manually pulling the valve core. This utility model can not only relieve pressure in a timely manner but also more precisely control the pressure relief amount, further ensuring the safety of the tire and vehicle driving.

[0005] To achieve at least one of the above advantages, the present application provides a tire air release valve, which includes a valve body, a regulation component, an air release component, and a barrier.

It should be understood that the present application is not limited by the exemplary embodiments described herein.

That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple.

Therefore, the above terms cannot be understood as a limitation on the present utility model.

[0033] As Figures 1-3 shown, the structure of the tire deflation valve according to the first embodiment of the present application is illustrated. It includes a valve body 1, a regulation assembly 2, a deflation assembly 3, and a blocking member 4. A through channel 10 is provided in the valve body 1. The blocking member 4 is detachably disposed in the valve body 1 to divide the channel 10 into an air inlet chamber 11 and a deflation chamber 12, wherein the air inlet chamber 11 is used to communicate with the tire valve.

[0034] Furthermore, the regulation component 2 is detachably connected to the upper end of the valve body 1 to regulate the connection length between the regulation component 2 and the valve body 1. Specifically, the regulation component 2 includes a connection part 21 and a regulation part 22. One end of the connection part 21 is connected to the regulation part 22, and the other end of the connection part 21 is threadedly and drivably connected to the valve body 1. The connection length between the connection part 21 and the valve body 1 can be regulated by twisting the regulation part 22. More specifically, the regulation part 22 is detachably sleeved on the connection part 21 through threads, and the connection part 21 is threadedly and drivably connected to the air leakage cavity 12. That is to say, by manipulating the regulation part 22, the connection part 21 is controlled to screw in or out along the thread, that is, the connection length between the connection part 21 and the valve body 1 is controlled. Preferably, a first digital display surface 211 is provided on the connection part 21, and a number of values are axially spaced on the first digital display surface 211. The values can represent the tire pressure threshold or the air leakage pressure magnitude.

[0035] Furthermore, the air leakage component 3 includes a valve core 31 and an elastic member 32. The valve core 31 is movably disposed in the valve body 1 and the regulation component 2, and the elastic member 32 is disposed between the valve core 31 and the regulation component 2. Specifically, the valve core 31 includes an operating rod 311 and a plug 312. The operating rod 311 partially exposes from the air leakage cavity 12 to the regulation component 2, the plug 312 is disposed in the air leakage cavity 12 and at one end of the operating rod 311. One end of the elastic member 32 abuts against the regulation component 2, and the other end abuts against the plug 312. The elastic member 32 always provides an elastic force that pushes the plug 312 towards the air inlet cavity 11.

[0036] In particular, as Figure 2 shown, a pneumatic needle 41 and a number of air inlets 42 are provided at the bottom of the barrier member 4. The air inlet cavity 11 and the air leakage cavity 12 are connected through the air inlets 42. Preferably, a conical inner wall 43 is provided at the top of the barrier member 4. Under the elastic force of the elastic member 32, the plug 312 drives the plug 312 to abut against the conical inner wall 43 to seal the air leakage cavity 12.

[0037] It should be understood that as Figure 3As shown, when the connection length between the connection part 21 of the control component 2 and the valve body 1 is longer, the deformation amount of the elastic member 32 is larger, and the provided elastic force is also larger. When the air pressure in the tire is too high, the gas pushes the valve core 31 and overcomes the elastic force of the elastic member 32, and the plug 312 is pushed to disengage from the conical inner wall 43. At this time, the sealing state of the air inlet cavity 12 is released, and the gas in the tire can flow out from the air inlet 42 through the air leakage cavity 12, thereby realizing the automatic air leakage of the tire air leakage valve; by setting in this way, the air pressure in the tire can be corresponded by the connection length between the connection part 21 and the valve body 1, and by setting the corresponding scale values on the first digital display surface 211, the air pressure in the tire can be artificially adjusted, that is, the control part 22 can be rotated to control the connection length of the connection part 21 by threads, and the preset threshold value or the air leakage amount of the air pressure in the tire can be set through the value on the first digital display surface 211 to ensure that the inside of the tire remains at or below the preset safety threshold value.

[0038] It is worth mentioning that the barrier member 4 is detachably and drivably arranged in the valve body 1 by threads, and a sealing member 5 is arranged between the barrier member 4 and the valve body 1 to prevent air leakage; in particular, a plurality of scale values 13 are arranged on the outer wall of the valve body 1 corresponding to the air leakage cavity 12, and the scale values 13 are distributed around the circumference of the valve body 1. It should be understood that the values on the first digital display surface 211 of the connection part 21 are axially distributed, that is, the value is changed by changing the axial connection length between the connection part 21 and the valve body 1. However, it is difficult to more finely reflect it in the form of axial values on the limited digital display surface by converting the rotational movement of the threads into an axial change amount. Therefore, in this application, the drivable barrier member 4 and the scale values 13 on the outer wall of the valve body 1 are used to more finely reflect the minute displacement generated by the rotational movement on the circumferential scale values on the outer wall of the valve body 1, so as to more finely fine-tune the air leakage amount in this way.

[0039] Preferably, as Figure 4 shown, the barrier member 4 can be rotated along the threads by inserting the operating member 6 into the two air inlets 42. Further, a pointer 61 can be provided on the operating member 6, and the pointer 61 points to the scale value 13 to intuitively show the change amount of the control value to the user.

[0040] As Figure 5 and 6As shown, the structure of the tire air leakage valve according to the second embodiment of the present application is illustrated. It includes a valve body 1, a regulation component 2, an air leakage component 3, and a barrier member 4. A through channel 10 is provided in the valve body 1. The barrier member 4 is detachably disposed in the valve body 1 to divide the channel 10 into an air inlet chamber 11 and an air leakage chamber 12, wherein the air inlet chamber 11 is used to communicate with the tire valve.

[0041] Further, the regulation component 2 is detachably connected to the upper end of the valve body 1 to regulate the connection length with the valve body 1. Specifically, the regulation component 2 includes a connection portion 21 and a regulation portion 22. One end of the connection portion 21 is connected to the regulation portion 22, and the other end of the connection portion 21 is threadedly and drivably connected to the valve body 1. The connection length between the connection portion 21 and the valve body 1 can be regulated by twisting the regulation portion 22; more specifically, the regulation portion 22 is integrally connected to the connection portion 21, and a coupling portion 14 is provided at the upper end of the valve body 1. The connection portion 21 is threadedly and drivably sleeved outside the coupling portion 14.

[0042] Preferably, a second digital display surface 141 is provided on the coupling portion 14, and a number of values are axially spaced on the second digital display surface 141.

[0043] Furthermore, the air leakage component 3 includes a valve core 31 and an elastic member 32. The valve core 31 is movably disposed in the valve body 1 and the regulation component 2, and the elastic member 32 is disposed between the valve core 31 and the regulation component 2; specifically, the valve core 31 includes an operating rod 311 and a plug 312. The operating rod 311 partially exposes from the air leakage chamber 12 to the regulation component 2. The plug 312 is disposed in the air leakage chamber 12 and at one end of the operating rod 311. One end of the elastic member 32 abuts against the regulation component 2, and the other end abuts against the plug 312. The elastic member 32 always provides an elastic force that pushes the plug 312 towards the air inlet chamber 11.

[0044] Particularly, an air needle 41 and a number of air inlets 42 are provided at the bottom of the barrier member 4 to connect the air inlet chamber 11 and the air leakage chamber 12 through the air inlets 42. Preferably, a conical inner wall 43 is provided at the top of the barrier member 4. Under the elastic force of the elastic member 32, the plug 312 drives the plug 312 to abut against the conical inner wall 43 to seal the air leakage chamber 12.

[0045] It is worth mentioning that the barrier member 4 is detachably and drivably arranged in the valve body 1 through threads, and a seal 5 is provided between the barrier member 4 and the valve body 1 to prevent air leakage; in particular, a number of scale values 13 are provided on the outer wall of the valve body 1 corresponding to the air leakage cavity 12, and the scale values 13 are distributed around the circumference of the valve body 1.
