Door checker for vehicle

The present invention relates to a door checker installed between a door and a body of a vehicle. More specifically, the shape of a conventional door checker is formed by constructing an operation part of a door checker that controls an open state of a vehicle door and serves as a stopper. The present invention relates to a vehicle door checker that can improve noise and improve durability by preventing friction with glass channels inside the door panel generated during operation of the door checker, and can be applied to a small vehicle.

In general, a vehicle (passenger car) is provided with a door to block the inside of the vehicle from the outside and prevent the passenger from jumping out of the vehicle. Glass is installed on the upper side of the door, the glass is fixed by a channel (channel), and moves up and down through the channel. The door is opened by driving and locked by a locking device to prevent an accident from occurring.

In addition, the door check is used to prevent the door from opening suddenly when the passenger opens the door for getting on or off. The door check is equipped with a hold mechanism that allows the door to be opened only halfway at first, and a stop function that stops while maintaining a constant angle when fully opened.

1 to 3 illustrate one embodiment of a door checker used in the related art, and use these to explain the operational state and problems in use.

The door checker 12 is fixed over the inside of the door 10 and the body portion of the vehicle, as shown in FIG. In the state in which the door 10 is closed, most of the door checkers 12 are moved to the inside of the door 10 to be hidden. When the door 10 is opened, the door checkers 12 are exposed to the outside as shown in the drawing. To prevent the (10) from opening suddenly. Reference numeral 14 denotes a door hinge.

FIG. 2 is a plan sectional view showing an installation state in a state where the door 10 is closed as an installation state of the door checker 12. As shown in FIG.

As shown, the fixing member 122 attached to the outer side panel 102 of the vehicle body, one end is fixed to the fixing member 122 by a pin 121 and the other end is a stopper pin 126 The check bar 123 is fixed, and the brake 10 is fixed to the door 10 and the check bar 123 penetrates.

The check bar 123 is normally inserted into the door and is exposed to the outside when the door is opened to serve as a brake. In addition, the check bar 123 has a curved shape as shown in order to avoid contact with the glass channel 18 in the small vehicle. The check bar 123 penetrates the inside of the braking unit 124 and performs a braking function due to interaction with the internal structure of the braking unit 124.

It is a structure. The braking part 124 has a guide 127 and a roller 125 therein, and the depression (a) formed in the check bar 123 passes through the guide 127 to primarily brake the door. have. Therefore, the door 10 of the vehicle is primarily limited in movement.

However, as shown in FIG. 2, the check bar 123 has a curved shape rather than a straight line. When the door 10 is opened and closed, the check bar 123 moves back and forth. The bar 123 has a collision with the glass channel 18 installed inside the door 10 in the structure. Therefore, in order to prevent the collision with the channel 18, the door checker 12 is manufactured in a curved form. In a small vehicle, since the inner space of the door 10 is narrow, many difficulties in forming the shape of the check bar 123 are encountered. there was.

In addition, since the check bar 123 always maintains its shape, when the door part of the vehicle is slightly deformed by an external impact, the check bar of the door checker collides with the panel or the glass channel 18 inside the door and friction noise is generated. There was a problem such as this occurs. In addition, since the shape of the check bar 123 has to be designed differently according to the door type of the vehicle to which the door check is applied, there is a problem in that it takes a lot of time and lacks compatibility.

The present invention has been proposed to solve the above problems, an object of the present invention is to improve the shape of the conventional door checker by configuring the connection portion of the door checker to control the open state of the vehicle door and acts as a stopper, The present invention provides a vehicle door checker that improves noise and durability by preventing friction with glass channels inside the door panel generated when the door checker operates.

Another object of the present invention is to provide a vehicle door checker having excellent variability that can be applied to all small, medium, or large passenger cars.

Referring to the present invention having such characteristics in detail as follows.

4 and 5 are a side view and a rear view of the vehicle door checker of the present invention, respectively. As shown, the door checker is a check bar composed of the position fixing piece 130, the connecting piece 131, the braking connecting pieces 132a, 132b, and the stop piece 133 from the left side, the check bar is penetrated through the door It consists of a braking part installed in the, and the state of the vehicle door is fully open.

The check bar according to the present invention is not a single bar shape as in the prior art, but a plurality of connecting pieces are interconnected, and when they open the door, they form a single bar shape as in the prior art and the door is closed. It is connected in a chain shape to face in the vertical direction. In accordance with the structure change of the check bar, the structure of the brake unit B is also changed.

The position fixing piece 130 is fixed to the fixing member 122 installed on the body of the vehicle by the fixing pin 121. This is the same as the fixing method of the conventional vehicle door check. However, at the other end of the position fixing piece 130, a protrusion 130b is formed. The protruding portion 130b has a rectangular shape at its end.

The connecting pieces 130, 131, 132a, 132b, and 133 of the present invention are all formed with protrusions and accommodating portions, and the functions are all the same, and thus, protrusions 130b and accommodating portions 130a are shown regardless of the connecting pieces. In addition, the slide pin 131 and the guide groove 140 is the same.

A sliding pin 131 is attached to the bottom surface of the position fixing piece 130. The slide pin 131 is slidably installed along a guide groove (not shown) formed on the bottom surface of the position fixing piece 130, and moves back and forth along the guide groove according to the movement state of the door to move the check bar of the present invention. Make it straight or chained. The slide pin 131 is moved by the elastic spring 135 installed in the brake unit. The elastic spring 135 may be configured using a lip spring or a leaf spring. The protrusion 130b is also formed with a pinhole (not shown).

An accommodating part 130a is formed at the connecting piece 131 which is coupled to the protrusion 130b of the position fixing piece 130. The accommodating portion 130a has a shape that is mated with the protrusion 130b and has a pinhole (not shown) therein. Therefore, the protrusion 130b and the accommodating part 130a are joined together, and the coupling is achieved by penetrating the pinhole 136 using the pin 137. The installation state of the pinhole 136 and the pin 137 is shown in Figs. 6A and 6B.

Since it is coupled by the pin 137 as described above, the position fixing piece 130 and the connecting piece (131, 132, 133) can be mutually rotated in the form of a chain. Therefore, when the door is closed, the check bar maintains the vertical direction without maintaining the horizontal state as in the prior art. In addition, the check bar remains in contact with the glass channel 18 even when moving inside the door of the conventional vehicle, and the layout problem in the small vehicle is also solved. A guide groove 140 to which the slide pin 134 and the slide pin 134 may move is also formed on the bottom surface of the connection piece 131.

Another end of the connecting piece 131 is formed with a projection 130b, which operates essentially the same as the projection 130b of the positioning piece 130.

Braking connecting pieces 132a and 132b are sequentially connected to the connecting piece 131. The braking connecting piece 132a is formed with an accommodating portion 130a which is formed with the protruding portion 130b of the connecting piece 131, and a protruding portion 130b is formed at the other end thereof, and a sliding pin 131 is formed at the bottom thereof so as to move back and forth. It is attached to the upper surface is formed with a left inclined surface.

The structure of the braking connecting piece 132a is the same as that of the connecting piece 131, and the difference is that the upper surface of the braking connecting piece 132a has a leftward inclined surface inclined toward the left side.

The left inclined surface is combined with another braking connecting piece 132b connected to the braking connecting piece 132a to perform a braking function such as a bent portion (a of FIG. 3) when opening a conventional door. The braking connecting piece 132b is essentially the same as the braking connecting piece 132a, except that the upper surface has a rightward inclined plane inclined toward the right side. Therefore, when the pair of braking connection pieces 132a and 132b are coupled to each other, they have a depression as shown in FIG. 4.

If necessary, it is possible to further connect another pair of braking connectors 132a and 132b to have a plurality of bends b. At this time, when the door is opened, the primary and secondary braking functions are performed by the bent portions. In addition, the door checker of the present invention may be applied to the door size of the vehicle by further inserting the planar connection piece 131. It is therefore apparent that it is applicable to the doors of all vehicles.

A fixing piece 133 is also connected to the braking connecting piece 132b. The fixing piece 133 is formed with an accommodating portion 130a that is coupled with the protrusion 130b of the braking connecting piece 132b, and the stopper pin 126 is fixed to the other end thereof. The fixing piece 133 has a similar shape to the connecting piece 131 and has a difference in that a stopper pin 126 is further attached to one end. The fixing piece 133 controls the degree of opening of the door when the door is opened to finally stop the door.

Referring to Figures 6a, 6b, and 6c look at the function and structure of the slide pin 134 for converting the check bar to a straight state or a chain state in the present invention as follows.

When the door is opened, the connecting piece 131 moves in the A direction, and the sliding pin 134 moves from the position of FIG. 6B to the position of FIG. 6A along the guide groove 140 indicated by the dotted line. Since it is restrained by the 135, it protrudes further in the direction of the protrusion 130b of the connecting piece 131. 6A and 6B are bottom views of the connecting pieces 131, respectively.

The protruding slide pin 134 is not shown in detail, but the guide groove 140 for supporting the slide pin 134 formed on the bottom surface of the receiving portion 130a of the braking connecting piece 132a connected to the connecting piece 131. Is inserted. When the insertion is completed, the connecting pieces 131 which are connected to each other are maintained in a straight state by the slide pin 134. Therefore, when the door is opened, all the connecting pieces 130, 131, 132a, 132b, and 133 passing through the brake part have an integrated structure as a bar.

Detailed structure of the slide pin 134 and the guide groove 140, referring to Figure 6c, to form a "T" shaped guide groove 140 in the center of the bottom surface of the connecting piece 131, the guide groove 140 A part of the slide pin 134 is coupled to the inserted state. The slide pin 134 has an “H” shape and is coupled to expose a portion of the connecting piece 131 to the outside. Therefore, the portion inserted into the guide groove 140 is moved back and forth along the guide groove 140, the portion exposed into the guide groove 140 is moved back and forth by contact with the elastic spring 135. . The guide groove 140 is formed in the longitudinal direction of the bottom surface of the connecting piece 131. The same is true for the other connecting pieces 132a, 132b, 133 and the like.

The elastic spring 135, referring to Figure 4, is installed in the braking part. The elastic spring 135 is in direct contact with the exposed portion of the slide pin 134 attached to the connecting piece 131. The elastic spring 135 is normally maintained while the slide pin 134 approaches and the slide pin 134 is exposed. The slide pin 134 moves while being in contact with the portion. This is because the slide pin 134 is automatically moved as the connecting piece 131 is moved to the outside by the opening of the door.

In addition, the guide 139, which is installed inside the brake unit to guide the movement of the slide pin 134, is configured in a flat shape so that the slide pins 134 moving inside the brake portion maintain the parallel state. Will be. This form of the guide 139 is important because the slide pin 134 is inserted into the guide groove 140 formed in the connecting piece 132a other than the connecting piece 131 to which it is installed. On the other hand, the guide adjacent to the upper side roller 138 should have a shape protruding downward to achieve the braking effect.

In the vehicle door checker of the present invention having the structure as described above, the checker bar has a straight line shape as shown in FIG. 4 when the door of the vehicle is completely opened, and the state of the door checker is stretched vertically rather than horizontally when the door is completely closed. Becomes Therefore, the problem occurring when the vehicle layout is solved because it does not occupy much space in the door as in the prior art. In addition, by increasing the number of connecting pieces 131 it can be applied to both small, medium or large vehicles.

According to the present invention, the connection part of the door checker, which controls the opening state of the vehicle door and serves as a stopper, is formed in a chain shape to improve the shape of the conventional door checker, and the inside of the door panel generated when the door checker is operated. By preventing friction with the glass channel, noise and durability are improved, and it is particularly applicable to small vehicles.
