Problems solved by technology

[0003] However, when the existing door opening limit mechanism is used to maintain the door opening, especially to maintain the half-open opening, it does not prevent the opening of the car door beyond this opening.
Therefore, when a force in the opening direction is applied to the outside of the door that maintains the half-open opening against the intention of the user, the existing door opening limit mechanism cannot prevent the door from opening, and there is an obstacle that the door hits the side of the vehicle. things etc.

Embodiment 1

[0051] refer to Figure 1 ~ Figure 5B , the door opening degree limiting mechanism 10 according to Embodiment 1 of the present invention will be described. figure 1It is a schematic side view showing a vehicle V provided with the door opening limit mechanism 10 of the present embodiment.

[0052] In the vehicle V, a door D is rotatably connected to a vehicle body B via a hinge H. As shown in FIG. In addition, a door opening limit mechanism 10 is arranged between the door D and the body B. As shown in FIG.

[0053] Figure 2A Shown is the door opening degree limiting mechanism 10 of this embodiment. Figure 2A In , the vehicle body B and the vehicle door D are omitted for simplification of description. The door opening limit mechanism 10 is provided with a door opening limiter 11 , a locking link 12 , a stopper 13 , a bracket 14 and an opening adjustment block 15 . In addition, the opening adjustment block 15 is connected to an unillustrated operation portion via a connect...

Embodiment 2

[0099] In the door opening limit mechanism 10 of the first embodiment, only one opening adjustment block 15 is used to limit the opening of the door D. As shown in FIG. In contrast, refer to Figure 8 ~ Figure 9B , to describe the door opening limiter according to Embodiment 2 of the present invention provided with two opening adjustment blocks having different distances from the abutting portion abutting against the door opening limiter to the abutting portion abutting against the stopper agency40. In the door opening limit mechanism 40 of the second embodiment, two opening adjustment blocks having different distances from the abutting portion abutting against the door opening limiter to the abutting portion abutting against the stopper are used, Thus, the opening degree of the door D can be restricted in stages. In addition, the operation, function, etc. of the opening degree adjusting block of the door opening degree limiting mechanism 40 are the same as those of the open...

Embodiment 3

[0117] In Embodiment 2, two opening adjustment blocks that rotate around the rotation axis and have different distances from the abutting portion abutting against the door opening limiter 41 to the abutting portion abutting against the stopper portion 13 are used. 45, 48 to limit the opening of the door D in stages. In contrast, refer to Figure 10 , the door opening limit mechanism 50 that restricts the opening of the door D in stages using the second opening adjusting block disposed between the first opening adjusting block and the stopper portion will be described. The door opening limit mechanism 50 of the present embodiment has the same structure as the door opening limit mechanism 50 of the first embodiment except that the second opening adjustment block is arranged between the first opening adjustment block and the stopper. Bit mechanism 10 is the same. Therefore, the description will focus on differences from the door opening degree limiting mechanism 10 of the first...

Abstract

A door checking mechanism comprising: a movement limiting member configured so as to be attachable to vehicle doors; a check link configured such that one end thereof is rotatably attachable to a vehicle body, said check link extending inside a vehicle door and being relatively movable in the longitudinal direction of the check link, relative to the movement limiting member; a stopper section provided on the other end of the check link extending inside the vehicle door; and an opening adjustment block that rotates relative to the check link. The opening adjustment block includes: a first contact section that comes in contact with the movement limiting member; and a second contact section that faces the first contact section, has a prescribed distance from the first contact section, and comes in contact with the stopper section. The opening adjustment block rotates towards the check link and, when the first contact section comes in contact with the movement limiting member and the stopper section comes in contact with the second contact section, limits the movement of the check link towards the one end side of the check link.

Description

technical field [0001] The invention relates to a vehicle door opening limit mechanism. Background technique [0002] A general car door is connected to the car body in a rotatable manner via a door hinge on one side, and can be kept fully open or half-open by a door opening limit mechanism arranged between the side and the car body. The specified opening degree (open action position). [0003] However, when the existing door opening limit mechanism is used to maintain the door opening, especially the half-open opening, it does not prevent the door from being opened beyond the opening. Therefore, when a force in the opening direction is applied to the outside of the door that maintains the half-open opening against the intention of the user, the existing door opening limit mechanism cannot prevent the door from opening, and there is an obstacle that the door hits the side of the vehicle. things etc. [0004] Therefore, as shown in Patent Document 1, it is proposed to use ...
