Description

Automotive Tire Pressure Control Unit {TIRE PRESSURE CONTROLLING SYSTEM}

The present invention relates to a vehicle tire air pressure control device, specifically, the driver can adjust to increase or decrease the air pressure of the car tire according to the driving environment of the car to increase fuel economy and may occur due to the tire pressure is not suitable The present invention relates to an automobile tire air pressure control device installed on an automobile wheel to prevent an accident occurring in advance.

In general, wheels installed in a vehicle are composed of tires and wheels, and the automobile wheels share the entire weight of the vehicle together with the tires, and the braking and driving torque, the impact on the road surface, the centrifugal force at the time of turning and the vehicle are inclined. It is designed to withstand the lateral forces that occur when it is composed of a rim, a disk, and a hub that connects the rim with the rim. A tire is overlaid along the rim of the rim to form an automobile wheel.

On the other hand, in order for the wheels to function properly, it is important to properly maintain the air pressure inside the tire. The tire air pressure is a pressure applied by the air filled in the air tube configured inside the tire. The durability is reduced, and the rolling resistance is increased, and the bad influence such as the steering performance is deteriorated. On the other hand, if the air pressure of the tire is higher than normal, the vehicle body shakes greatly even in the small impact during high-speed driving, and in particular, if the vehicle is suddenly stopped during high-speed driving in rainy weather, the risk of accidents is increased.

Therefore, in case of continuous driving, it is necessary to check the air pressure of the tire every day, and in the case of general vehicles, it is necessary to check the condition of the tire by measuring the air pressure about once a month to maintain the proper tire air pressure. It is important. However, in the process of checking the air pressure of the tire as described above, the general user judges whether or not the air pressure of the tire is rough by pressing the tire with his hand or pressing the foot with his foot. It is difficult to know the exact air pressure and adequacy of the tire, and this has caused a problem that most maintenance shops have to go through a cumbersome process of measuring and supplementing the tire pressure.

In order to solve the above problems, the Korean Utility Model Registration No. 20-0195637 proposed a tire air pressure checking device, but this simply indicates the air pressure state of the car tires, and the driver immediately increases the air pressure of the car tires. There was a limitation that it can't be reduced or reduced, and Korea Patent Registration No. 10-0217655 suggested an active countermeasure system for maintaining the air pressure of automobile tires, but it works only when the tire air pressure drops and needs to be increased. The problem remains that active replacement is not possible if the tire pressure needs to be reduced.

The present invention has been made to solve the above problems and to overcome the limitations, and according to the change in the driving environment of the vehicle, the driver can selectively inject or exhaust the air inside the car tire to adjust the air pressure of the tire to improve fuel economy It is an object of the present invention to provide an automobile tire air pressure regulator that is economical by increasing, and can prevent the occurrence of various accidents due to tire air pressure problems.

In addition, the control unit, the pressure sensor and the electric valve for controlling the automobile tire air pressure control device according to the present invention by generating electricity through the self-power generation during the operation of the vehicle to store and use it to be environmentally friendly and energy It is another object of the present invention to provide an automobile tire pressure control device that can not only save, but also have a trouble free structure.

An automobile tire air pressure adjusting device according to the present invention includes: a compressed air tank integrally attached to one side of an outer circumferential surface of a hub shaft formed between rims of an automobile wheel, and having an air inlet formed on one side thereof; An exhaust tank which is integrally attached to the other side of the outer circumferential surface of the hub shaft and has an exhaust port formed at one side thereof; One side is in communication with the compressed air tank and the pipe installed with the electric valve, the other side is in communication with the exhaust tank through the pipe with the electric valve is installed, the other side is in communication with the air inlet of the air tube inside the tire Trident connector; A sensor unit installed between the rim of the wheel of the vehicle and the air tube of the tire, the sensor unit comprising a pressure sensor measuring tire air pressure and a pressure information transmission line transmitting pressure information measured by the pressure sensor; A controller for displaying the tire pressure information transmitted from the sensor unit to the driver and receiving a driver's selection signal to selectively transmit a signal controlling the opening and closing of each electric valve to each electric valve through a control signal transmission line; And a power supply unit protruding from the outside of the vehicle wheel and producing and supplying electric power required for the operation of the electric valve, the sensor unit, and the control unit.

At this time, the electric valve is preferably a solenoid valve, because it can be used in the opening and closing valve that can open and close the high pressure air with a small power. Therefore, it is normally closed because it does not supply electricity, but when the power is supplied, the valve is opened by the force of the electromagnet to supply the compressed air stored in the compressed air tank to the air tube or discharge the tire air to the exhaust tank. Exhaust is exhausted through the exhaust port of the exhaust tank.

Of the components of the automobile tire pressure control device according to the present invention, the power supply unit is connected to the wheel drive shaft of the automobile generator to produce electricity by the rotation of the rotating shaft, the shaft is coupled vertically downward to the outer surface of the generator A weight that allows the generator to be fixed even when it is rotated by itself, is coupled to the generator and is characterized in that it is composed of a battery for storing electricity produced from the generator and a power supply line for supplying electricity from the battery.

In addition, the generator is inserted into the housing body and the bearing attached to the inner side of the housing body and the bearing and the shaft and one side is connected to the wheel drive shaft and the other side of the shaft and the permanent magnet is coupled to the permanent magnet It is characterized in that it is composed of an annular coil which is installed on the other inner side of the housing main body in an annular circumference and an electric transmission line connected to the annular coil to supply electricity to the outside.

Therefore, as the wheels of the automobile are driven, the shaft, which is integrally connected to the driving shaft, rotates by itself, thereby generating electricity by the principle of Faraday in the coil forming the motor through the reaction of the motor. At this time, as the shaft is rotated by itself, a permanent magnet integrated with the shaft in an annular coil installed inside the generator only when the generator having its own rotating shaft interlocked with the drive shaft of the wheel for the vehicle is fixed in its own position. This is because electricity can be generated through the rotation of.

At this time, the weight is formed in a fan-shaped form that becomes wider from the upper to the lower it can be said to be stable because the center of gravity of the weight moves more toward the bottom. On the other hand, it is preferable that the power supply line is inserted into an etch groove formed by etching on the surface of the wheel of the vehicle, which is installed. This is to reduce the probability of occurrence.

The vehicle tire air pressure adjusting device according to the present invention is bolt-attached to the outside of the vehicle wheel, a thin plate having a central protrusion protruding outward to form a built-in space that can accommodate a portion of the power supply in the center. Characterized in that it further comprises a protective cover of the form. At this time, it is preferable that the battery inner guide is formed on the inner surface of the central projection portion consisting of a projection of a polygonal shape for supporting one side of the battery to be fixed after being fitted into the inner space.

The protective cover is necessary to reduce the risk of damage that may occur during driving of the vehicle and to stably fix the battery because a part of the power supply part of the configuration of the present invention is exposed to the outside of the automobile wheel. Meanwhile, since the shaft of the generator is rotated in conjunction with the driving shaft of the vehicle, the battery built-in guide prevents the battery from being removed from the place where the battery is installed by affecting the peripheral devices due to the vibration and the like. In order to supply power smoothly.

According to the automobile tire pressure control device according to the present invention, the driver selectively injects or exhausts air to the tire according to the driving environment, thereby increasing or decreasing the air pressure to reduce the fuel consumption of the vehicle by reducing the fuel consumption of the vehicle. It is possible to increase and prevent the occurrence of various accidents due to the inadequate air pressure of the tire.

In addition, the electric power for driving the car tire pressure control device according to the present invention is also environmentally friendly in that it can be used after storing the electricity through self-generation by using only the rotational force of the wheel and the gravity of the weight itself when the vehicle is running. It has the advantage of saving energy.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a horizontal cross section of the vehicle tire air pressure control apparatus according to the present invention, Figure 2 shows a vertical cross section of the vehicle tire air pressure control apparatus according to the present invention.

The automobile wheel is composed of a rim 10 for supporting a tire and a disc 20 for supporting a rim. A hub shaft is formed between the rims 10 to connect the rims to the rims 10, and the wheel driving shaft 50 of the vehicle is directly bolted to the hub shaft. In addition, the disk 20 is installed toward the outer surface of the car wheel, the shaft disk 60 is connected to the wheel drive shaft 50 to the inner surface of the car wheel to prevent the departure of the wheel during driving separately laid It is.

Compressed air tank 100 and the exhaust tank 200, which is a component of the vehicle tire air pressure control apparatus according to the present invention are formed separately and integrally formed on the outer peripheral surface of the hub shaft in the space formed between the rim and the rim. At this time, the compressed air tank 100 should be formed separately in the compressed air inlet 110 on one side of the compressed air tank 100 so that the compressed air can be easily injected into the tank even outside the vehicle. Therefore, when the air pressure of the tire is lowered, the compressed air tank can directly inflate the air into the air tube 2, which is one of the elements constituting the tire 1, to increase the tire air pressure. (100) Since the compressed air must be transported into the air tube 2 of the tire, the pressure of the compressed air tank 100 should be higher than the air pressure of the air tube. Meanwhile, an exhaust tank 200 is installed separately from the compressed air tank 100. The exhaust tank 200 extracts air from the air tube 2 and exhausts it to the outside when the tire pressure needs to be lowered. In charge of. The reason why the exhaust tank 200 is separately installed is that the mass of the wheels is not uniform when the wheels are rotated, so that the rotational movement of the wheels is disturbed due to the momentum. In order to secure the distribution, it is preferable to install the exhaust tank 200 separately from the compressed air tank 100. In addition, the exhaust tank 200 should also be provided with an exhaust port 210 to allow the air to escape to the outside separately.

The connection part 300 is in communication with the compressed air tank connector 310 having the electric valve 311 therein and the exhaust tank connector 320 having the electric valve 321 therein and the air tube 2. It consists of an air tube connector 330. Therefore, the connecting portion is configured in three forms, it is preferable that it is configured in a T-shape. When the connection part 300 is in a normal driving state, all the valves are closed to prevent air from being distributed so that the tire maintains a constant pressure, and the compressed air tank 100 is increased to increase fuel efficiency due to a drop in air pressure inside the tire. In the case of supplying the compressed air to the air tube 2 of the tire, the electric power is supplied to the electric valve 311 installed in the compressed air tank connector 310 according to the electric valve opening / closing signal transmitted to the controller 500. By opening the valve to inject the compressed air into the air tube (2) at this time, while injecting the air to the control unit for operating the opening and closing of the electric valve while watching the pressure information transmitted from the sensor 400. On the other hand, when the air pressure inside the air tube 2 is high and the air is to be exhausted, the electric valve 321 installed in the exhaust tank connector 320 is opened in response to the signal of the controller 500 to open the inside of the air tube 2. The air of the exhaust tank 200 is to be exhausted. After that, the air exhausted to the exhaust tank is naturally exhausted through the exhaust port 210 installed at one side of the exhaust tank 200.

The sensor unit 400 is positioned between the rim and the air tube, and directly measures the pressure in the air tube to transfer the pressure information to the control unit 500 through the pressure information transmission line 410. The controller displays pressure information to the driver through the control unit. In this figure, a separate display device is not illustrated. In general, it is preferable to allow the driver to directly check the pressure information of the tire air tube through the display device installed in the instrument panel located in front of the driver's seat.

Meanwhile, the controller 500 receives and transmits the pressure information and controls the injection or exhaust signal of the compressed air transmitted from the driver through the control signal transmission line 510 to adjust the air pressure of the air tube. It will be in charge of controlling and delivering it.

In addition, the vehicle tire pressure control apparatus according to the present invention, the power required to operate the control unit 500, the electric valves (311, 321), the sensor unit 400 is a generator 610 separately installed in the outer center of the automobile wheel, The battery 620 and the power supply line 630 are supplied through the power supply unit 600 is driven to be driven. On the other hand, the generator 610 is a permanent magnet installed at one end of the shaft 611 in the generator 610 by the rotation of the shaft 611 and the shaft 611 rotated in conjunction with the wheel drive shaft 50 As the rotation is rotated, a storage battery 620 for directly receiving and supplying electricity generated in the annular coil surrounding the permanent magnet is installed. Meanwhile, a weight 640 is formed on the lower side of the outer side of the generator to prevent the generator 600 from moving out of position or shaking due to the rotation of the shaft 611. It plays a role of not being.

Meanwhile, in order to protect the power supply unit 600, a protective cover 700 having a thin plate shape is further formed at the center of the vehicle wheel to protrude outward from the center portion. At this time, a circular or polygonal protrusion line is formed on the bottom of the inner surface of the central protrusion 710 to form a predetermined battery internal space 730 therein so that the battery 620 of the components of the power supply unit can be stably fixed. It is preferable that the battery pack guide 720 formed thereon is formed.

Figure 3 illustrates in detail the configuration of the power supply unit of the components of the automobile tire air pressure control apparatus according to the present invention, Figure 4 is a coupling structure of the power supply unit which is one of the components of the automobile tire air pressure control apparatus according to the present invention Is shown in cross section.

The power supply unit 600 is largely composed of a generator 610, a storage battery 620, a power supply line 630, a weight 640. In particular, the generator 610 is installed through the housing body 616 and the housing body 616, the shaft 611 rotates in conjunction with the wheel drive shaft, the side where the shaft disk 60 of the inner surface of the housing body is located. The bearing 612 is provided in an annular shape to assist the rotation of the shaft 611, the permanent magnet 614 is integrally coupled to the other side of the shaft 611 and located in the housing body 616 and the permanent An annular coil 613 disposed inside the housing body 616 along the circumference of the magnet 614 and an electric transmission line 615 for transferring electricity generated from the annular coil to the storage battery 620. Therefore, as the wheel drive shaft is rotated, the shaft 611 rotates in conjunction with this, and the permanent magnet 614 integrally coupled to the shaft 611 rotates at a high speed inside the annular coil 613, thereby providing Faraday's law. As a result, electricity is generated in the annular coil 613. The electricity generated in this way is transmitted to the storage battery through the electric transmission line 615 and stored and distributed through the power supply line 630 where each power is needed. At this time, in order to smooth the rotation of the shaft 611 and minimize the friction, a bearing 612 is installed around the shaft. In this figure, a ball bearing is illustrated. On the other hand in order to ensure that the fixed generator is fixed without being separated from the seat on the lower side of the housing body 616 of the generator is provided with a weight 640 provided in a fan shape of the upper side down toward the down side the generator and power It is responsible for ensuring that the supply unit is fixedly supported. When the shaft 611 rotates at a high speed, the generator 610 may also rotate and move together, so that the weight 640 is essentially configured to prevent the outer surface of the housing body 616 constituting the generator. It is preferable to install downward.

On the other hand, the generator 610 is connected adjacent to the storage battery 620, the inside of the center projection 710 of the protective cover 700 in order to be firmly supported and avoid the impact applied from the outside while driving the vehicle After inserting and supporting the battery 620 in the battery interior space 730 formed through the battery interior guide 720 formed in the space, the protective cover is firmly bolted to a disk located on the outer surface of the vehicle wheel. It is fixed tightly.
