Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise indicated, terms of orientation such as "upper, lower, left, right" and "inner, outer" are generally defined with reference to the orientation of the drawing figures, and "inner, outer" refer to the inner and outer of the contours of the corresponding components.

The present disclosure provides a tire valve control device, as shown in fig. 2, including a control body extending along an axial direction, the control body having therein a connection section 5 for connection with a valve section 4 of a tire and a control section 6 in fluid communication with the connection section 5, and the control section 6 being provided with a gas outlet 31, a power source 32, a detection portion 33, a control portion 34 and an actuating portion being provided in the control section 6, the detection portion 33 being configured to detect a current water pressure and feed back to the control portion 34, the control portion 34 causing the power source 32 to supply power to the actuating portion to push a thimble 41 of the valve section 4 when the current water pressure exceeds a preset value, so that gas in the tire flows out to the gas outlet 31.

The control unit 34 can receive the water pressure information detected by the detection unit 33, and when the vehicle falls into water, the water pressure information exceeds a threshold value, and the control unit 34 causes the power source 32 to supply power to the actuation unit to push the ejector pin 41 of the air nozzle segment 4. The ejector pin 41 is an inherent component of an automobile air tap, namely a valve core ejector pin, and in a normal state, when the ejector pin 41 is pushed, gas is released from the inside of a tire, and the "fluid communication" here means that gas or liquid can flow between the two components, and in the present disclosure, gas can flow between the control section 6 and the connecting section 5. Therefore, when the control portion 34 controls the actuating portion to push the ejector pin 41, gas can be made to enter the air bag 1 from inside the tire through the gas outlet 31 of the tire air valve control device, so that the automobile floats, thereby realizing self rescue.

Alternatively, as shown in fig. 2, in the present embodiment, the actuating portion includes an electromagnet 36 and a pushing member, the electromagnet 36 is electrically connected with the control portion 34, the pushing member is slidably disposed in the control body and has an armature 361 disposed corresponding to the electromagnet 36, and when the electromagnet 36 is powered, the armature 361 moves to the electromagnet 36 so that the pushing member pushes the ejector pin 41. The actuating portion, which is composed of the electromagnet 36 and the pusher, can be simply and effectively electrically connected to the control portion 34, so that the control portion 34 effectively controls the actuating portion.

Specifically, as shown in fig. 2, in the present embodiment, the tire air valve control device is provided with a partition 35, the outer periphery of which partition 35 is fitted to the inner wall of the control body and is formed with a guide hole at the radial center, the pusher includes a pusher rod 362 movably passing through the guide hole, one end of the pusher rod 362 is connected to an armature 361 formed in a plate shape, the other end is connected to a top plate 363 near the ejector pin 41, and the electromagnet 36 is formed as a ring-shaped electromagnet provided between the partition 35 and the armature 361. Two sections of the ring electromagnet along the longitudinal section are shown. The annular structure facilitates winding of the electromagnetic coil.

The guide hole provided at the center of the partition 35 can restrict the radial movement of the push rod 362 so that the push rod 362 reciprocates only in the axial direction. After the electromagnet 36 is powered, the plate-shaped armature 361 is attracted to move, so that the push rod 362 and the top plate 363 are driven to push the thimble 41 to start the inflation process of the air bag 1, namely, the air is inflated into the air bag 1 from the tire along the direction A. When the automobile falls into water and needs to save oneself, the control part 34 makes the power supply 32 energize the electromagnet 36, and the electromagnet 36 generates magnetic force after being energized, so as to attract the armature 361 to move to the position of the electromagnet 36. Because the attractive force of the electromagnet 36 to the armature 361 is axial, when the armature 361 moves, the pushing member can be driven to move axially, so that the thimble 41 is pushed to release gas.

Alternatively, in the present embodiment, a spring 37 may be provided between the diaphragm 35 and the armature 361, the spring 37 being sleeved outside the push rod and abutting the diaphragm 35 and the armature 361, respectively. When the automobile falls into water, the electromagnet 36 is electrified and attracts the armature 361 to move; the spring 37 is compressed at this time; when the gas in the air bag 1 tends to be saturated, the control part 34 cuts off the power supply 32, the attraction force of the electromagnet 36 to the armature 361 disappears, and at the moment, the spring 37 pushes the armature 361 to return to the initial position, so that the push rod and the top plate 363 are far away from the thimble 41, and the air bag 1 is inflated.

Alternatively, in the present embodiment, the spacer 35, the armature 361, and the top plate 363 are respectively formed with the air guide holes 364. Specifically, the air guide holes 364 may be formed as through holes spaced apart in the circumferential direction of the spacer 35, the armature 361, and the push plate. Through this gas vent 364, gas can more quickly pass through the tire valve control device after being released from the tire, thereby entering the bladder 1 and inflating. When the car falls into water, it is necessary to inflate the airbag 1 as soon as possible, i.e. to start self-rescue, so that losses can be minimized.

For the tire valve control device provided by the present disclosure, optionally, in this embodiment, the control portion 34 is a control circuit connected between the power source 32 and the actuating portion and including an MCU, i.e., a micro-programmed controller (Microprogrammed Control Unit), with a built-in hydraulic pressure threshold. Specifically, the control circuit may be composed of an MCU and a relay control unit. When the control circuit works, the MCU is awakened by the timer once every 500ms, and the rest time is in a sleep state. When the MCU is awakened, the MCU can receive the A/D signal transmitted by the detection part 33 and compare the signal with the built-in water pressure threshold after calculating the water pressure information; when the calculated water pressure information exceeds the built-in water pressure threshold value for 10 seconds continuously, the MCU controls a relay in the relay control unit to work, so that the electromagnet 36 is driven to attract the armature 361, the pushing piece is driven to push the thimble 41, and the air bag 1 is inflated; when the air bag 1 pressure is sufficient to float the vehicle, the MCU turns off the relay and stops inflating the air bag 1. Specifically, the power supply 32 of the control portion 34 may be provided by a battery built in the control section 6, and in this way, the circuit arrangement cost generated by the power supply of the vehicle to the tire air valve control device may be effectively avoided, so that the tire air valve control device provided by the present disclosure has a higher integration level and is more convenient to use. In addition, the controller for setting the water pressure threshold value can be other control elements known in the art, such as a PLC.

Optionally, in this embodiment, the connecting section 5 is formed with a thread connected to the air valve section 4 of the tire, and one end of the control section 6 is connected to the connecting section 5, and the other end is opened to form the gas outlet 31. The tire air tap control device 3 provided by the disclosure can be conveniently installed or detached from the air tap section 4 through threaded connection, and the installation or detachment process is simple and convenient; on the other hand, the screw connection can ensure air tightness, and the air inflation efficiency is reduced due to poor sealing performance in the air inflation process of the air bag 1, so that the safety of a vehicle can be ensured.

The present disclosure also provides a tire air valve, which includes an air valve section 4 mounted on a tire, a thimble 41 for controlling air flow on-off is provided in the air valve section 4, the tire air valve further includes the above-mentioned tire air valve control device 3, and a connection section 5 of the air valve control device is connected with the air valve section 4 and is in fluid communication. The air valve section 4 is provided with the tire air valve control device 3, so that the air bag 1 is automatically inflated when the vehicle falls into water.

The present disclosure also provides a self-rescue over water tire comprising a tire body, as shown in fig. 1, the self-rescue over water tire further comprising the above-described tire valve and an air bladder 1, the air bladder 1 being disposed in a hub central bore and in fluid communication with a gas outlet 31 of the above-described tire valve control device 3. Specifically, in the present embodiment, the bladder 1 may be connected to the gas outlet 31 of the above-described tire air cap control device 3 through the conduit 2. More specifically, the conduit 2 is screwed with the gas outlet 31. The air bag 1 is arranged in the central hole of the hub, so that the structure of the wheel can be effectively utilized, and the design cost is reduced. When the vehicle falls into water, the self-rescue tire can automatically inflate the air bag 1, and after the air bag 1 is inflated, the hub center hole cover can be jacked up to release the volume, so that self-rescue is realized.

The disclosure also provides a vehicle comprising the above-mentioned self-rescue tire. When the vehicle falls into water, the vehicle can automatically inflate the air bag 1 preset in the vehicle, so that the vehicle floats on the water surface, and self rescue is realized.

In summary, the present disclosure describes a tire valve control device, a tire valve, a self-rescue tire in water, and a vehicle. When the automobile falls into water, the detection part in the tire air valve control device can detect the water pressure information and transmit the A/D signal to the MCU in the control circuit, and when the water pressure information is confirmed to exceed the built-in water pressure threshold value, the MCU controls the relay in the relay control unit to work, so that the electromagnet is driven to attract the armature, the pushing piece is driven to push the thimble, and the air inflation process of the air bag is started. By the mode, self rescue can be carried out without external equipment when the vehicle falls into water, and the safety of the vehicle and the personnel is ensured.

The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.

In addition, the specific features described in the foregoing embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, the present disclosure does not further describe various possible combinations.

Moreover, any combination between the various embodiments of the present disclosure is possible as long as it does not depart from the spirit of the present disclosure, which should also be construed as the disclosure of the present disclosure.
