Check link structure of car door

The present invention relates to a check link of an automobile door, and more particularly, in the construction of a door check link configured to allow the roller ball to be released by a spring to move and open the door while moving the strap. By replacing the magnet with a magnet, it is necessary to provide a grease, which is a lubricant, to prevent the wear of the strap, and to further improve the durability and performance of the door check link.

In general, the door of the car is a structure that greatly affects the characteristics, structure, and design of the vehicle. Most of the passenger car doors use a front hinge rear open type, but as a special type of door, a sliding door that moves and opens along the side of the vehicle body There is a hinge on the roof or front pillar, and the wing wing is opened and closed.

In addition, the outer panel and the inner panel are hemmed and coupled to the panel of the door. The outer panel is usually made of steel, and since the rigidity of the surface varies depending on the design, a reinforcement may be attached to the rear surface. Recently, in order to reduce the weight, there is an example of using a thin plate or aluminum or resin.

The inner panel is made of steel plate of almost the same thickness as the outer panel. In contrast to the outer panel, the inner panel is formed of a thick processed product, and a door regulator, a door hinge and a door sash are installed, and an installation part and a belt line opening of each part are required. Strengthen according to the performance.

The door opening and closing system is composed of a door hinge, a door check link, a door handle, and a door lock, and since the door hinge supports a heavy door, two doors are normally set up and down to support the door and open and close the door. In order to perform the function, such a hinge should have high endurance reliability because of its high frequency of use, and should have high strength reliability such that the hinge body is not separated even if excessive impact input such as a collision is applied, and the material of the hinge body, The method is made of steel sheet press or cast iron, and the bushing is used to contain a sintered alloy such as a hinge pin to ensure slippery rotation and durability.

In addition, the door check link performs a stop function when the door is half open and a stopper function when the door is unfolded, and high durability is required because the door check link has a high frequency of use.

The door handle has an outside handle for opening and closing from the outside of the car and an inside handle for opening and closing in the car. The door handle has a function of opening and closing the door and unlocking the door lock through the link system.

The roller ball 12b holding the elastic force can move the protrusions 11a and the grooves 11b of the strap 11 and keep the door 30 half open or unfold.

At this time, a grease, which is a lubricant, is applied between the roller ball 12b and the strap 11 to smooth the operation, and reduce wear and noise caused by friction between the roller ball 12b and the strap 11.

However, since the grease loses lubricity at -30 ° C, the range of temperature that can be used is limited, and the grease itself causes the occurrence of joints and malfunctions, and the roller ball 12b and the strap 11. Wear and noise due to friction of the roller ball 12b, malfunction due to the rust resistance and water resistance of the roller ball (12b) occurs, and when water flows into the check link 10 of the door 30, There was a problem that caused a malfunction caused by freezing.

Therefore, an object of the present invention is to solve the above problems, by using a magnet and the strap and roller ball constituting the check link of the door to perform the role of the check link by using the repulsive force and attraction of each other It is to provide a check link structure of a car door that prevents wear and joints of parts without using lubricant, and can use the check link semi-permanently and further improve durability and performance.

The object of the present invention is connected to the vehicle body, and constitutes a strap configured as a protrusion and a groove, each protrusion is composed of an N pole magnet, a groove is composed of an S pole magnet, N on both sides of the strap This is achieved by installing the moving tool of the pole magnet in the inner panel of the door by the housing.

In the present invention, when the door is opened or deployed, the movable tool moves along the strap connected to the vehicle body. In this case, the movable tool maintains the reaction force when the movable tool is located at the protrusion of the strap. As the manpower acts as a check ring, no additional lubricant is required, and wear and malfunction can be prevented, durability and performance can be improved, and life can be used semi-permanently, thereby achieving the above object.
