Weather Strip Sealing Force Controller
The present invention relates to a device that can adjust the sealing force of the vehicle weather strip, and more particularly, the sealing force control device of the weather strip to fill the air inside the weather strip so that the weather strip always has a constant contraction force (Sealing Control) Device of Weather Strip).
In general, the door or trunk lid of the vehicle is equipped with a weather strip made of elastic material to prevent rain, water, or fine dust from entering the vehicle interior or the trunk room, and to absorb shock when opening or closing the door or the trunk room. there was.
2 is a cross-sectional view showing a structure in which a weather strip is mounted on a door of a conventional vehicle. As shown in the drawing, the vehicle has a weather strip for sealing the door 1 and the body 2 of the vehicle body to provide watertightness. On the body side and the door side, respectively. The first weather strip 3 mounted on the body side is in contact with the door surface, and the second weather strip 4 mounted on the door side is in contact with the body side surface. The interior and exterior could be doubled off. That is, when the second weather strip is mounted on the door side and closes the door, the second weather strip contacts the body surface to seal the inside and the outside of the vehicle, and the first weather strip is mounted on the body side to play the same role by contacting the door surface. . Then, there is a door glass run 5 between the door 1 and the door glass 6 to seal the space between the door 1 and the door glass 6. In addition, the second weather strip 4 has a hollow cylindrical structure with an empty inside. When the user closes the door, the second weather strip is pressed by the force and the contact area with the body 2 is increased. It is enlarged and the adhesion is increased to increase the seal between the vehicle interior and the exterior.
However, in the conventional weather strip as described above, when the long time elapses, the durability of the weather strip decreases, the deformation occurs in the shape of the weather strip, and the sealing force decreases. As described above, the sealing force of the weather strip decreases. Therefore, it is not possible to provide sufficient watertightness between the inside and the outside of the vehicle, so that rainwater is infiltrated into the inside of the vehicle, and when the vehicle runs at high speed between the door and the body, noise is generated.
Thus, the present invention is devised to solve the above problems,
The present invention relates to a sealing force control device for a weather strip that fills air into an inner space of the weather strip so that the weather strip can maintain a constant shape at all times, so that the weather strip can maintain a constant sealing force at all times.

DESCRIPTION OF SYMBOLS 1: Door 2: Body 3: 1st weather strip 4: 2nd weather strip 5: Door glass run 10: Door 11: Body 12: 1st weather strip 13: 2nd weather strip 14: Air injection pipe 15: Air pump 16: control unit 17: vehicle speed sensor 19: central cavity
In order to achieve the above object, the present invention is a weather strip having a central cavity to be installed on the vehicle body and the door to seal between the inside and the outside of the vehicle to provide watertightness; An air injection pipe connected to the central cavity of the weather strip;
A vehicle speed sensor for detecting a driving speed of the vehicle; And air injection means for injecting air through the air injection pipe according to a signal input from the vehicle speed sensor.
Hereinafter, with reference to the accompanying drawings a preferred embodiment of the sealing force control device of the weather strip according to the present invention in detail as follows.
3 is a cross-sectional view taken along the line A-A of Figure 1, showing the structure of the weather strip sealing force control apparatus according to the present invention.
The present invention is mounted on the door 10 to close the door 10, the second weather strip 13 to contact the surface of the body 11 to seal the inside and outside of the vehicle, and the body 11 is mounted on the side of the door and The first weather strip 12, which contacts and seals the inside and outside of the vehicle, is installed in the vehicle. Each of the weather strips 12 and 13 has a cylindrical structure in which a central cavity 19 is formed. In addition, an air injection pipe 14 is coupled to the first weather strip 12 through the first weather strip 12 from the outside to the central cavity 19. In addition, an air pump 15 for injecting air through the air inlet pipe 14 is provided in the central cavity 19 of the first weather strip 12, and the air pump 15 according to an input signal. Manufacturing unit 16 for controlling the operation of the) is installed. In addition, a vehicle speed sensor 17 for detecting a driving speed while driving the vehicle and inputting a signal thereof to the controller 16 is provided.
Referring to the operation of the present invention configured as described above are as follows.
The vehicle speed sensor 17 detects the traveling speed of the vehicle while driving the vehicle. The detected vehicle speed is input to the controller 16, and the controller 16 operates the air pump 15 according to the input signal to supply air through the air injection pipe 14 to the first weather strip ( It is to be injected into the central cavity 19 of 12). Since the air is injected into the central cavity 19 of the first weather strip 12 as described above, the first weather strip 12 can always maintain a constant shape so that the door 10 and the body ( 11) it will be able to provide watertightness. In addition, the negative pressure acting on the door 10 also increases according to the traveling speed of the vehicle, thereby greatly increasing the force of the door being pushed out. Accordingly, the higher the vehicle speed detected by the vehicle speed sensor 17 is, the controller 16 is configured to increase the amount of air injected through the air pump 15, so that the first weather strip 12 Regardless of the speed of travel of the vehicle, it will always be able to have a constant sealing force.
As can be seen by the embodiment, by the weather strip sealing force control device according to the present invention, even if the weather strip is elapsed for a long time, the shape is not deformed will always have a suitable sealing force, always watertightness with a suitable sealing force Since it is provided that the phenomenon of rain or fine dust flow into the vehicle is prevented, and the noise generated by the air between the vehicle interior and the outside is prevented to provide a comfortable driving environment.
