As a section capable of embodying a door operation force is secured to be long, the door checker has durability, allows the door to stand still in three or more stages, makes an operation force embodiment section at least twice as long as an existing door checker, and provides operation force having the same emotional aspect as an existing hinge separated door checker.

Description

[0001] The present invention relates to a hinge integral type door checker using a gear ratio,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door checker integrated with a door hinge as a type using a gear ratio.

In general, the role of the door checker is to lock the door in the middle portion by closing the door, and to prevent the door from suddenly closing by the tilted or wind.

The door of the vehicle is different for each vehicle, but it has a weight of about 40kg or more, and if it is suddenly closed during a person's descent, it may cause injury, so the role of the door checker is important.

In addition, the door checker also serves to make the door feel a sense of theft when opening and closing the door.

Usually, door checkers have two hooks. Depending on the type of vehicle, the front door has three stages and the rear door has two stages.

As one example of such a door checker, US Patent Publication No. US2020233814 discloses a hinge integrated type door checker.

The hinge integrated type door checker mounts the rotary slider on the hinge shaft and determines the rotation amount of the rotary slider as the hinge is opened.

Therefore, if the door open amount is 70 °, the groove can be formed in the rotating slider section by 70 °.

In addition, most of the conventional hinge integrated type door checker including the hinge integrated type door checker is a structure in which the cylinder-shaped projection passes through the groove of the rotary slider to implement the operating force of the door.

However, in the case of the hinge integrated type door checker, a protrusion is required to be formed on the rotary slider in a short interval corresponding to the door pull opening angle, so that the interval between the ends is shortened and the durability is deteriorated. It is difficult to implement the door stop.

In addition, since the hinge integrated type door checker must implement the operating force in a short interval, it is not possible to implement an emotional side operating force such as the conventional hinge detachable door checker, and only the door stop function can be implemented.

SUMMARY OF THE INVENTION Accordingly, the present invention has been conceived in view of the above circumstances, and it is an object of the present invention to provide a gear shift mechanism, which is a combination of two gears, in which the first gear, which rotates in the same manner as the hinge shaft, It is possible to secure a long section in which the door operating force can be realized, which is advantageous in terms of durability performance and a gear ratio capable of realizing a door stop of three or more stages And an object of the present invention is to provide a hinge integrated type door checker.

Another object of the present invention is to provide a hinge integrated type door checker using a gear ratio that can realize an emotional side operating force in the same manner as a conventional hinge detachable door checker because the operating force implementing section can be made longer than two times.

In order to achieve the above object, a hinge integrated type door checker using the gear ratio provided in the present invention has the following features.

The hinge integrated type door checker using the gear ratio has a first gear mounted on a hinge shaft of a door and rotating together with a hinge shaft, a second gear rotating in engagement with the first gear, and a plurality of grooves formed around an outer periphery A rotating slider rotatable about a pin, and a stopper for restricting the rotation of the rotating slider while being coupled to the groove in the rotating slider.

Therefore, the hinge integrated type door checker using the gear ratio is characterized in that the operating force of the door checker can be freely implemented by setting the rotation amount of the rotary slider relatively larger than the door opening amount through the gear ratio of the first gear and the second gear .

Here, the hinge integrated type door checker using the gear ratio may further include a case accommodating therein the first gear, the second gear, the rotary slider, the stopper, and the like.

It is preferable that the number of teeth of the first gear is set larger than the number of teeth of the second gear.

In addition, the upper end of the hinge shaft passes through the rotary slider, and an arc-shaped slot that can eliminate interference during rotation can be formed.

In the case of the stopper, the plunger may be inserted into the groove of the rotary slider to press the rotary slider, and a spring that elastically supports the plunger from the rear side.

The hinge integral type door checker using the gear ratio provided in the present invention can operate the rotary slider at a greater angle than the door full open angle by using the gear ratio to implement the operating force in a long section, And it is possible to realize an emotional side operating force in the same manner as a conventional hinge detachable door checker.

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

FIG. 1 is a perspective view of a hinge integrated type door checker using gear ratios according to an embodiment of the present invention. FIG. 2 is a perspective view illustrating a combination of a hinge shaft and a second gear in a hinge integrated type door checker using a gear ratio according to an embodiment of the present invention. A case structure including a first gear, a second gear and a rotating slider, and a coupling structure of the first gear, the second gear, and the rotating slider, respectively.

As shown in Figs. 1 and 2, the hinge integrated type door checker using the gear ratio secures the rotation angle of the rotary slider to be larger than the door pull opening angle by using the engagement combination of the two gears, It is made of a structure that can be freely made.

A fixed hinge 19 provided on a vehicle body side and a rotary hinge 20 provided on a door side are coupled by a hinge shaft 10. A first gear 11 is fixed to an upper end of the hinge shaft 10, And the first gear 11 at this time can be rotated together with the hinge shaft 10 when the hinge shaft 10 is rotated.

A cylindrical case 17 is disposed on one side of the upper end of the hinge shaft 10 on which the first gear 11 is mounted and a rotary slider 15 and a stopper 16 and the like can be accommodated.

For example, a cylindrical slider 15 and the like can be housed in a cylindrical case body. A stopper 16 is housed in the housing 21, which extends integrally with the side surface of the case 21, .

Here, the entire case 17 including the housing 21 can be installed and fixed on one side of the fixed hinge 19 on the vehicle body side through a bracket (not shown) .

Of course, the case 17 can be constructed in a prefabricated structure in which a component such as the rotary slider 15 can be inserted therein.

A hole 22 is formed in the bottom surface of the case 17 so that the upper end of the hinge shaft 10 on which the first gear 11 is mounted can be inserted into the case .

In the case 17, a disc-shaped rotary slider 15, which rotates in conjunction with the rotating hinge shaft 10, is horizontally disposed. The rotary slider 15 thus disposed passes through the center of the rotary slider 15 And is rotatable together with the pin 14 while being supported by upper and lower ends of the case 17 supported by the pins 14 rotatably supported at both ends.

In particular, the second gear 12 is mounted on the lower end of the pin 14 serving as the rotation center axis of the rotary slider 15, and the second gear 12 mounted on the pin 14 is mounted on the hinge shaft 10 1 gear 11, so that the engagement of the two gears can be achieved.

That is, when the hinge shaft 10 rotates when the door is opened, the first gear 11 and the second gear 12 are engaged with each other, and the rotating slider 15 can be rotated.

The number of teeth of the first gear 11 is greater than the number of teeth of the second gear 12 so that the second gear 12 is relatively two to three times more It becomes possible to rotate a lot.

For example, when the gear ratio of the first gear 11 and the second gear 12 is 2: 1, the second gear 12 can rotate twice as much as the first gear 11 The second gear 12 rotates by 140 ° while the first gear 11 rotates by 70 ° and the rotating slider 15 rotates by 140 ° even after the first gear 11 rotates by 70 ° .

This makes it possible to secure a larger angle of rotation of the rotary slider 15 than in the door full opening angle and consequently to provide a section (length) capable of forming the groove portion 13 on the outer peripheral surface of the rotary slider 15, So that a large number of grooves 13 can be formed by using such a long section, and at least three or more door stops can be realized.

A plunger 16a of a stopper 16 to be described later is seated on each of the grooves 13 formed in this way and is engaged with the rotation of the plunger 16a. The rotation of the slider 15 is constituted, so that the door stop can be made at the position where the plunger 16a is held in the groove 13.

The rotary slider 15 is formed with an arc-shaped slot 18 concentric with the center of the pin 14 through which the pin 14 passes. As shown in Fig.

The rotary slider 15 can be guided by the hinge shaft 10 which moves relatively along the slot 18 without interference with the hinge shaft 10 during rotation.

At this time, the slot 18 may have a length enough to cover the rotation angle of the rotation slider 15. For example, when the rotation slider 15 rotates by 140 degrees, It is possible to have a length formed over an angle section exceeding 140 DEG.

The stopper 16 is provided as means for restricting the rotation of the rotary slider 15 while being coupled to the groove 13 in the rotary slider 15. [

The stopper 16 is constituted by a front plunger 16a and a rear spring 16b provided inside the housing 21 in the case 17 and the plunger 16a has a spring 16b And is inserted into the groove portion 13 of the rotary slider 15 to press the rotary slider 15. [

Accordingly, the operating state of the hinge integrated type door checker using the gear ratio thus constructed will be described below.

FIG. 3 is a plan view showing an operating state of a first gear, a second gear, and a rotary slider in a hinge integrated type door checker using a gear ratio according to an embodiment of the present invention. FIG. Fig. 6 is a plan view showing each step of opening a door in the hinge integrated type door checker. Fig.

3 and 4, in the door closed state, the plunger 16a of the stopper 16 has a plurality of grooves 13 in the rotary slider 15, for example, the first of the three grooves 13 And is in a state of being bound to the groove portion 13.

When the door is opened, the rotary hinge 20, the hinge shaft 10 and the first gear 11 in the hinge shaft 10 are rotated, and the second gear 12 engaged with the first gear 11 is rotated, .

The rotation of the second gear 12 causes the rotation slider 15 including the pin 14 to rotate in the direction of the arrow and then the stopper 16 in the first groove 13 of the rotation slider 15, The plunger 16a of the plunger 16a rides over the protruding portion and is engaged with the second groove portion 13 that follows the plunger 16a.

The plunger 16a of the stopper 16 in the second groove 13 of the rotating slider 15 continues to ride over the projecting portion And is tied to the third groove portion 13 that continues to the next, and this position becomes the two-door opening state of the door.

According to the present invention, a sufficient number of grooves can be provided by sufficiently securing a section in which the grooves can be formed, so that it is possible to provide a wide range of door stop positions such as two-stage and three-stage.

5 is a graph showing a relationship between an opening angle and a load in a hinge integrated type door checker using a gear ratio according to an embodiment of the present invention.

As shown in Fig. 5, the rotation amount of the rotary slider 15 is relatively increased compared to the previous one, that is, the distance between the groove portion and the groove portion is secured, The operating force in the section shifted to the opening position of each stage can be smoothly or smoothly reduced. Therefore, it is possible to realize the same emotional operating force as the conventional hinge detachable door checker.

As described above, according to the present invention, when the hinge is fully opened, the rotational slider is rotated more by using the gear ratio, so that the operating force of the door checker can be freely implemented. Accordingly, Can be implemented.
