Therefore, the door checker 100 for the vehicle is prevented from being broken by the foreign matter generated in the checker arm 110.

Hereinafter, the operation of the vehicle door checker 100 described above will be described in detail.

5 is an operation diagram showing a first operation of the door checker 100 for a vehicle shown in FIG. FIG. 6 is an operation diagram showing a second operation of the door checker 100 for automobile shown in FIG. 1. FIG. 7 is an operation diagram showing a third operation of the door checker 100 for a vehicle shown in FIG. 1.

5 to 7, the user stops using the vehicle and opens the door. At this time, the user applies a force to the outside of the vehicle to the door. The door is opened by the force of the user.

When the door is opened, the movable body 140 fixed to the door moves. The checker arm 110 is variable in length according to the movement of the movable body 140. At this time, one side of the checker arm 110 is rotatably fastened to the vehicle frame. Therefore, while the length of the checker arm 110 is variable, it rotates in one direction.

On the other hand, if the length of the checker arm 110 is variable while rotating, the moving body 140 is variable in length as described above. At this time, the first ball 161 disposed inside the moving body 140 moves the first ball flow hole 111 formed in the checker arm 110.

When the door is opened as described above, the first ball 161 moves along the first ball flow hole 111. A plurality of seating holes 112 are formed in the first ball flow hole 111 as described above. When the first ball 161 moves along the first ball flow hole 111, it passes through each seating hole 112. At this time, each seating hole 112 temporarily prevents the movement of the first ball 161 to temporarily control the operating radius of the door.

On the other hand, if the user continues to apply force to the door, the first ball 161 continues to move along the first ball flow hole (111). At this time, the first elastic portion 181 continuously applies an elastic force to the first housing 171. Accordingly, the first ball 161 continuously contacts one surface of the first ball flow hole 111 without departing from the first ball flow hole 111.

If the user continues to apply force to the door, the first ball 161 continues to move along the first ball flow hole 111. At this time, the cross-sectional area of the checker arm 110 is different. That is, the cross-sectional area of the checker arm 110 is increased as described above.

When the cross-sectional area of the checker arm 110 becomes large, the first ball 161 is pushed into the moving body 140 along the surface of the checker arm 110. The first housing 171 is also pushed to one side of the movable body 140 together with the first ball 161. When the first ball 161 is pushed into the movable body 140, the length of the first elastic portion 181 is shortened.

When the length of the first elastic portion 181 is shortened, the elastic force increases. The first ball 161 exerts a stronger force on the checker arm 110 by the increased elastic force. Therefore, the frictional force formed on the first ball 161 and the checker arm 110 is increased. Therefore, the opening speed of the door is reduced by the friction force after a certain period.

On the other hand, the user supplies the lubricating oil through the first lubricating oil supply hole. At this time, the supplied lubricating oil is stored in the first lubricating oil flow hole 171e through the first lubricating oil supply hole. The lubricant stored in the first lubricant flow hole 171e reduces the friction between the first ball 161 and the checker arm 110 when the first ball 161 rotates.

The checker arm 110 is supported by the second housing 172 fastened to one side of the checker arm 110. That is, when the first ball 161 exerts a force on the checker arm 110, it is supported by the second housing 172. In addition, the second housing 172 moves along the checker arm 110 together with the first housing 171.

When the door rotates repeatedly, the checker arm 110 is contaminated with various foreign substances. The foreign matter contaminates the checker arm 110 and prevents the rotation of the first ball 161. At this time, a part of the foreign matter contaminated by the checker arm 110 is removed by the first housing 171 and the second housing 172.

The removed foreign matter is discharged to the outside through the first foreign matter release hole 171a and the second foreign matter release hole 172a. Therefore, it is possible to prevent the contamination of the checker arm 110 by the foreign matter.

As described above, the vehicle door checker 100 improves the operation feeling of the door when the user opens the door. In addition, the lubricating oil may be supplemented at any time to prevent the door checker 100 for the vehicle from being broken. The door checker 100 for a vehicle is simple in the assembly process and the assembly cost is reduced.
