Abstract
Description
Technical Field

[0002] In many situations, it's necessary to deflate vehicle tires, such as during off-road driving, to improve tire grip and ensure a smoother ride, as such tires compress less and become more flexible when encountering rocks and potholes. Typically, a special key is used to remove the valve core, and after the tire reaches the required pressure, the core is replaced and locked with the key. This is currently considered the fastest method for deflating tires. This invention aims to improve the deflation method in a faster and more convenient way. Summary of the Invention

[0016] The main objective of this invention is to provide a tire valve 1, which includes a valve stem 10, a valve core 20, and a secondary air release mechanism 30. The tire valve 1 is designed to be mounted on a rim 100 of a wheel 200 of a vehicle 300, for inflating and deflating a tire 400 mounted on the rim 100 in a conventional manner, and also for rapid deflation via the secondary air release mechanism 30.
[0017] The secondary air release mechanism 30 includes an electric air valve 31, a power supply 32, an electronic card 33, and an antenna 34. Preferably, the electric air valve 31 is very small, even miniature. The electric air valve 31 can be of various types; for example, when current is applied to the solenoid, it generates a magnetic force that affects the position of a plunger connected to a seal, and depending on the plunger's position within the valve body, the seal opens or closes the valve orifice. These are referred to in this disclosure and the claims as the open state and the closed state.
[0018] The electric air valve 31 includes an air inlet 312 and an air outlet 311. Air can flow into the electric air valve 31 through the air inlet 312 and out through the air outlet 311. The secondary air release mechanism 30 operates electrically, therefore it includes a power source 32, which can be a battery or a rechargeable battery. An internal energy harvester that generates electrical energy using the movement of the vehicle wheels charges the battery. The electric air valve 31 is remotely activated by sending a signal to the antenna 34, which transmits the signal to the electronic card 33 to open or close the electric air valve 31.
[0019] The valve stem 10 includes a tubular air passage 11 and a secondary outlet 12. The secondary outlet 12 is designed to allow air to flow out of the tire 400 through the electric air valve 31 in the open state and out of the wheel 201 through the tubular air passage 11 and the secondary outlet 12. Air can flow from the outlet 311 of the tubular air passage 11 to the inlet 111. The valve stem 10 also includes a standard main air passage 14 and a standard main top opening 13. Air can flow out of the tire through the standard main top opening 13 and can be inflated into the tire through the standard main top opening 13.
[0020] We want to clarify that the normal operation of the tire valve, such as inflating at a gas station or bleeds air by changing the valve core state or removing a key from the valve core, is feasible and remains unchanged. The special feature of this invention lies in the secondary air release mechanism, the secondary outlet 12 located on the side wall of the valve stem, the tubular air passage within the valve stem, and the electric air valve. Based on a remote command issued by a remote controller 500 to the antenna in the secondary air release mechanism, the secondary air release mechanism can rapidly bleed air from the wheel through the secondary outlet. In another embodiment, the tire valve 1 includes a pressure sensor 35, thus knowing the pressure inside the wheel (by electronic circuitry or a remote controller), and the remote controller can send a command to the secondary air release mechanism to reduce the pressure inside the wheel to a specific pressure, and the tire valve 1 will act accordingly.
[0021] Another embodiment of the invention relates to a system 2 for releasing air from a tire 400 mounted on a wheel 200. The system 2 for releasing air from a tire in this embodiment includes: a tire valve 1 and a remote controller 500 configured to send a command to the tire valve to release air from the wheel. The main design objective of this embodiment is to allow a user to send a command to the tire valve to release air from the wheel using a remote controller (e.g., their smartphone), and to determine how much air is released (how much pressure is left in the wheel). Each wheel can be controlled individually based on the identification number of the tire valve.
[0022] Another embodiment of the invention relates to a system 3 for releasing air from a tire, the system 3 comprising: the tire valve 1 and the remote controller 500. The system 3 of this embodiment further includes a GPS unit 36 located inside the tire valve, for example, inside the secondary air release mechanism 30, either as part of the remote controller 500 (e.g., using a built-in location on a smartphone) or separately. In this embodiment, the remote controller 500 is designed to send the signal to the antenna 34 of the tire valve 1 to operate the secondary air release mechanism to an open or closed state based on the vehicle's position and desired wheel pressure. The remote controller is configured to identify the tire valve position, representing the vehicle's position, via the GPS unit, and, upon identifying the vehicle's position, send the command to the tire valve to release air from the wheel. In this embodiment, when the remote controller detects that the vehicle is in an off-road state (possibly at a specific time and / or at a specific distance from the road), the remote controller sends a signal to deflate the tires to the required pressure.
[0023] Another embodiment of the invention relates to a system 4 for releasing air from a tire of a wheel mounted on an unauthorized vehicle. The system 4 for releasing air from a tire of a wheel includes: the tire valve 1 and the remote controller 500. In this embodiment, the tire valve further includes a processor 37 and a displacement sensor 38. The processor 37 has a unique identifier for a specific tire valve mounted on the wheel of the vehicle, and the displacement sensor 38 is designed to detect movement of the vehicle (movement of the sensor itself represents movement of the vehicle). The processor is configured to send an automatic opening command to open the electrically operated valve to deflate the tire after a predetermined time has elapsed since the displacement sensor detected that the vehicle has begun to move. Preferably, the processor may be configured not to send the automatic opening command upon receiving a presence signal from the remote controller, the presence signal indicating the presence of an authorized user of the vehicle. It should be clarified that in the system 4 for releasing air from a tire of one wheel in this embodiment, the remote controller 500 is designed to send a signal to the antenna 34 of the tire valve 1 when unauthorized use of the vehicle is detected, to operate the secondary air release mechanism to open it (the system is essentially an anti-theft system where the tires are deflated when a thief uses the vehicle). Other types of sensors can be used, whose detections represent the vehicle's intended use.
[0024] The system 4 for releasing air from a tire of a wheel may further include a GPS unit, and the processor is configured to send the automatic opening command to open the electric air valve to deflate the tire after the GPS unit detects that the vehicle is outside a predetermined area set by a user in the remote controller for a predetermined time. In this embodiment, the processor may also be configured not to send the automatic opening command upon receiving a presence signal from the remote controller.
[0025] The processor can also be configured to send the automatic opening command to open the electric air valve to deflate the tires after a timer 371 in the processor detects that the vehicle has moved for a predetermined period of time within a specific time period set by a user in the remote controller. The processor can also be configured not to send the automatic opening command when it receives the presence signal from the remote controller.
[0026] Another embodiment of the invention relates to a system 5 for releasing air from the tires of a vehicle wheel, comprising: four tire valves (a first tire valve 1A, a second tire valve 1B, a third tire valve 1C, and a fourth tire valve 1D) respectively mounted on four tires (a first wheel 200A, a second wheel 200B, a third wheel 200C, and a fourth wheel 200D) of a vehicle wheel, and said tire valves 500. Each tire valve also includes said processor and a touch sensor 39, said processor having said unique identification code for a specific tire valve, said touch sensor being designed to detect a touch on said valve stem of said tire valve. The plurality of processors of the plurality of tire valves are configured to send an automatic opening command to open the electric air valve to deflate the tire when at least two of the four tire valves detect touch of the valve stem of at least two tire valves, and wherein the processors are configured not to send the automatic opening command when the presence signal is received from the remote controller.
[0027] The purpose of the system 5 for releasing air from the tires of a vehicle's wheels is to prevent thieves from attempting to block the secondary outlets 12 to prevent tire leaks. Therefore, if the valve stems of two tire valves are touched within a short period of time (predefined) (assuming their secondary outlets are blocked), the remaining two tires will immediately deflate, and then the thief will find the tire valves and close the secondary outlets of the tire valves (e.g., using glue).
[0028] Preferably, in these systems, the command to release air is first sent as a message to the owner's registered mobile phone number. Only after the owner confirms the message will the command be executed by the secondary air release mechanism. (This is to prevent accidental air release when the owner or their representative is driving or using the vehicle, or when the driver is off-roading but does not need to release wheel pressure.)
