Abstract

PURPOSE: A temporary repairing apparatus of a flat tire for a vehicle is provided to travel normally by keeping internal pressure of the flat tire continuously during traveling by straining the tire with centrifugal force and by contacting with pressure changes. CONSTITUTION: A temporary repairing device of a flat tire is composed of a sealing unit(10) moving out of a tire(T), and shutting off the flat portion of the tire; an expansion unit(20) moving the sealing unit to the outside of the tire and the rim with centrifugal force; and a moving unit(30) combined with the expansion unit, and turning with the rim of the tire. A moving shaft(21) of the expansion unit is expanded out of the tire, and moved with rotating the tire during traveling. The moving unit is turned, and the sealing unit is moved around the tire with difference of centrifugal force in placing the expansion unit outside the tire. The flat portion of the tire is shut off with a housing(11) by suction force from outflow of tire pressure in placing the sealing unit in the flat tire. Lowering of the tire pressure is prevented, and traveling is performed stably with straining by centrifugal force.

Description

An automotive deflated tire having a temporary repair device

The present invention relates to a tire puncture temporary recovery device for vehicles, and more particularly to a tire puncture temporary recovery device for vehicles that can prevent the outflow of air in the tire by the centrifugal force during the puncture during driving of the vehicle.

In general, the tire of the vehicle must maintain proper air pressure when driving to prevent unnecessary increase in braking distance or excessive consumption of fuel during braking or driving. Therefore, the tire T can directly inject air when the pressure decreases. It is to be provided with an air inlet exposed to the outside.

However, such an air inlet A of the tire T has no choice but to use an air injection pumping tool in a state where the vehicle is stopped. In addition, if a puncture occurs while driving, tire pressure cannot be maintained, resulting in immature driving operation. There is a problem that can cause a large accident.

Accordingly, the present invention has been made in view of the above-described matters, and its object is to maintain normal tire pressure even when a puncture occurs in the tire of the vehicle so that normal driving can be performed.

The present invention for achieving the above object, the sealing means for moving to the outside of the tire to block the puncture, the expansion means for moving the sealing means through the centrifugal force to the outside of the tire and the rim portion and this expansion and contraction It is characterized by consisting of a moving means coupled to the means and rotated with the rim of the tire.

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

Figure 1 shows a block diagram of a tire puncture temporary recovery device for a vehicle according to the present invention, the present invention is moved to the outside of the tire (T) sealing means for blocking the puncture portion and the sealing means ( 10) the expansion means 20 for moving the centrifugal force to the outside of the tire (T) and the rim (R) and the expansion means (20) coupled with the rim (R) of the tire (T) It consists of a moving means 30 is rotated.

Here, the sealing means 10 is an open U-shaped block having an airtight member 11b of rubber material at the other portion where the tire T internal pressure flows through the opened pressure hole 11a. A moving plate 12 fixed to the housing 11 and the elastic housing 13 made of a coil spring in the blocking housing 11 and moved by the pressure introduced through the pressure hole 11a; It consists of a sensor 14 provided on the inner wall to detect the movement of the moving plate 12 and to transfer the electrical signal to the ECU.

In this case, a rubber pad 12a is padded on the movable plate 12.

In addition, the expansion means 20 is a bellows type made of a stretchable material is stretched through the centrifugal force generated by the rotation to secure one end to the housing 11 to move the sealing means 10 to the outside of the tire (T). The moving shaft 21 and the connecting shaft 22 is formed integrally with the moving shaft 21 and rotates together with the moving means 30.

The moving means 30 is coupled to the fixed member 31 fixed to the rim R and to be relatively rotated at intervals so that the connecting shaft 22 of the expansion and contracting means 20 is fitted to the fixed member. It is made of a moving member 32 is rotated by the pressing force of the connecting shaft 22, the inclined moving surface (31, 32) has a serrated shape corresponding to each other as shown in Figure 2 ( Pressing surfaces 31b and 32b perpendicular to 31a and 32a are formed.

Hereinafter, the operation of the present invention will be described in detail.

When the tire T rotates as the vehicle travels, the moving shaft 21 of the expansion and contraction means 20 positioned close to the rim R receives the centrifugal force and extends to the outside of the tire T.

Then, as shown in FIG. 3, when the expansion means 20 is completely tensioned and positioned outside the tire T, the expansion means 20 is mounted on the sealing means 10 and the rim R positioned outside the tire T. Due to the difference in the centrifugal force acting on the moving means 30, the moving means 30 is gradually rotated so that the sealing means 10 moves along the tire T.

That is, the centrifugal force acting on the sealing means 10 located on the outside of the tire T acts relatively larger than the centrifugal force acting on the moving means 30 mounted on the rim R, and thus the means 10 A force to move the expansion and contraction means 20 connecting the 30 is actuated (in the direction of the arrow in FIG. 3), and as a result, the connecting shaft 22 of the expansion and contraction means 20 moves as shown in FIG. 4. It moves along the moving surfaces 31a and 32a formed in the members 31 and 32 of 30. As shown in FIG.

Subsequently, the connecting shaft 22 of the stretching means 20 moved along the moving surfaces 31a and 32a of the members 31 and 32 is in contact with the pressing surface 32b of the moving member 32 and thereby moves. The connecting shaft 22 of the stretching means 20 which receives the force greater than the centrifugal force acting on the means 30 through the milling means 10 continuously presses the pressing surface 32b of the moving member 32. It will rotate slowly.

On the other hand, when the sealing means 10 which is gradually moved along the circumference of the tire T is located at the puncture portion of the tire T, the housing 11 is punctured by the suction force caused by the outflow of the tire T pressure. It will block the site.

At this time, the airtight member 11b provided in the housing 11 blocks the puncture portion of the tire T, of course.

Subsequently, when the housing 11 of the sealing means 10 is positioned at the puncture portion of the tire T, as shown in FIG. 5, the internal pressure of the tire T may open the pressure hole 11a of the housing 11. As it flows through it, the moving plate 12 is moved to the puncture portion.

At this time, it is a matter of course that the spring which is the elastic member 13 fixed to the movable plate 12 is tensioned.

Then, when the moving plate 12 is located in the detection sensor 14 provided in the housing 11, the ECU that detects the position change of the moving plate 12 through the electrical signal of the detection sensor 14 is the driver Will tell the puncture of the tire (T) through the lamp or buzzer.

As described above, according to the present invention, the tire is moved along the circumference while being tensioned to the outside of the tire by the centrifugal force and closely adhered by the pressure change due to the puncture, thereby preventing the pressure drop of the tire. Of course it is.
