Description

  The present invention relates to a vehicle door structure.

The vehicle door is provided with an outer handle that is operated to open the door body.
For example, in Patent Document 1, an arm portion of an outside handle (corresponding to “outer handle” in claims) is engaged with a vehicle body via an outside handle rod (corresponding to “rod” in claims). A structure that is connected to a mating door lock assembly (corresponding to a “latch mechanism” in the claims) is described. The outside handle and the door lock assembly can be linked via an outside handle rod.

When the user operates the outside handle and rotates it around the support shaft, the outside handle rod is displaced downward, and the engagement member of the door lock assembly moves in conjunction with the displacement of the outside handle rod. To do. Thereby, engagement with a vehicle body and a door lock assembly is cancelled | released, and a door main body can be made into an open state.
By the way, in this type of vehicle door, for example, when an impact load is input from the outside of the vehicle, it is important that the engagement between the door main body and the vehicle body is not released by an unexpected force.

Japanese Patent No. 3259798

However, the conventional vehicle door structure still has problems in the following respects.
When an impact load is input from the outside of the vehicle, the door outer panel of the door body moves toward the inside of the vehicle. Thereby, the outer handle attached to the door outer panel also tries to move to the inside of the vehicle. As a result, the outer handle moves relative to the latch mechanism attached to the door inside panel of the door body. Then, the rod is displaced downward in conjunction with the movement of the outer handle, and the engagement between the latch mechanism and the vehicle body is released. That is, the outer handle is in a state of being operated by a user in a pseudo manner due to an impact load from the outside of the vehicle, and thus there is a possibility that the door body is in an open state.

  Therefore, the present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle door structure capable of preventing the door body from being opened when an impact load is input from the outside of the vehicle. .

In order to solve the above-described problem, a vehicle door structure (for example, the vehicle door structure 2A in the embodiment) according to the invention described in claim 1 includes an opening (for example, the vehicle 1 in the embodiment) (for example, the vehicle 1). The door main body (for example, implementation) provided by the door outer panel (for example, the door outer panel 22 in the embodiment) and the door inner panel (for example, the door inner panel 21 in the embodiment). Door body 5) in the form and attached to the door outer panel, and operated to release the engagement between the door body and the vehicle body (for example, the vehicle body 1A in the embodiment) to open the door body. An outer handle (for example, the outer handle 7 in the embodiment), and the outer handle extending in the vertical direction of the vehicle. A rod (for example, the rod 12 in the embodiment) that displaces downward when the outer handle is operated to disengage the door body and the vehicle body, and from the outside of the vehicle.

The outer handle 7 is attached to the door outer panel 22. The outer handle 7 is operated to open the door body 5.
FIG. 4 is an explanatory diagram of the outer handle 7. In FIG. 4, only the outer handle 7 and the rod 12 are shown, and the door body 5 (see FIG. 1) is not shown.
As shown in FIG. 4, the outer handle 7 is provided with a base block 31 attached to the door outer panel 22 (see FIG. 1) and a grip that is provided outside the door outer panel 22 (see FIG. 1) and is operated by the user. And a rotation block 35 that is rotatably supported by the base block 31 via a rotation shaft 34 and has an arm portion 36.

The base block 31 is fastened and fixed to the door outer panel 22 (see FIG. 1) with, for example, a bolt (not shown).
The grip 33 is pivotally supported on the door outer panel 22 (see FIG. 1) via a support shaft (not shown). The grip portion 33 is rotated around a support shaft (not shown) with respect to the door outer panel 22 (see FIG. 1) by being operated by the user.
The rotation block 35 is configured such that the arm portion 36 rotates around the rotation shaft 34 in conjunction with the rotation operation of the grip portion 33.
A return spring 32 is provided between the rotating block 35 and the base block 31. The return spring 32 is, for example, a so-called torsion coil spring, and urges the tip 36a of the arm portion 36 upward.
The tip 36 a of the arm portion 36 moves downward in conjunction with the turning operation of the gripping portion 33 when the user grips and turns the gripping portion 33. Further, when the user releases the gripping portion 33, the distal end 36a of the arm portion 36 moves upward and stops at a predetermined position by the urging force of the return spring 32.

As shown in FIG. 3, the rod 12 is made of, for example, a rod-like metal material such as iron, and is provided so as to extend in the vertical direction of the vehicle 1. The upper end portion 12 a of the rod 12 is connected to the tip 36 a (see FIG. 4) of the arm portion 36 in the outer handle 7.
As shown in FIG. 2, the lower end 12 b of the rod 12 is connected to the latch mechanism 10. Further, the lower end portion 12 b of the rod 12 is provided with a bent portion 13 that bends outward in the inner and outer directions of the door body 5. The operation and effect of the bent portion 13 will be described later.

  The latch mechanism 10 has a movable piece 41 that can move up and down. The lower end 12b of the rod 12 is connected to the movable piece 41. The movable piece 41 of the latch mechanism 10 is connected to the arm portion 36 (see FIG. 4) of the outer handle 7 via the rod 12 and can be interlocked with the arm portion 36.

FIG. 5 is an explanatory view of the latch mechanism 10 and is a perspective view as seen from obliquely rearward. In FIG. 5, the door inner panel 21 is shown in a transparent manner, and the outer shape of the door inner panel 21 is indicated by a two-dot chain line.
As shown in FIG. 5, the latch mechanism 10 is fixed to the door inner panel 21 with a bolt (not shown), for example, behind the door body 5 and below the outer handle 7 (see FIG. 1).
The latch mechanism 10 has a striker opening 43 at a position corresponding to the striker 9 (see FIG. 1). The striker opening 43 has an engagement piece 45 that can be engaged with the striker 9. The door inner panel 21 is provided with an inner panel opening 21 a at a position corresponding to the striker opening 43.

The engagement piece 45 engages with the striker 9 that enters the striker opening 43 through the inner panel opening 21 a of the door inner panel 21 when the door body 5 is closed. Thereby, the door main body 5 can maintain a closed state.
Further, the engaging piece 45 is adapted to be interlocked with the movable piece 41 (see FIG. 2). Specifically, when the movable piece 41 moves downward, the engagement piece 45 rotates in the striker opening 43 and the engagement between the striker 9 (see FIG. 1) and the engagement piece 45 is released. . Therefore, when the user operates the outer handle 7 to rotate the grip portion 33, the tip 36a of the arm portion 36 moves downward to displace the rod 12 downward, and the lower end portion 12b of the rod 12 The connected movable piece 41 moves downward in conjunction with the displacement of the rod 12. Thereby, since the engagement between the latch mechanism 10 of the door body 5 and the striker 9 of the vehicle body 1A is released, the door body 5 can be brought into an open state.

The regulating member 50 is a plate-like member formed by, for example, pressing a metal material such as iron, and has a longitudinal direction in the vertical direction as a whole and a lower end portion of the rod 12 in the width direction of the door body 5. It is arranged so as to straddle directly under 12b.
The restriction member 50 includes a connection part 51, a displacement restriction part 53, an extension part 57, and a peeling part 59.

  The connecting portion 51 is provided at the lower end portion of the regulating member 50. The connecting portion 51 is located in front of the lower end portion 12 b of the rod 12 in the width direction of the door 2 (corresponding to “one side” in the claims) and faces the left-right direction of the vehicle 1. The connecting portion 51 is joined to the inner surface of the rear leg portion 25b of the stiffener 25 by, for example, welding.

  The displacement restricting portion 53 extends above the connecting portion 51 and extends in the vertical direction at an intermediate portion in the vertical direction of the restricting member 50. The displacement restricting portion 53 is the lowest when the lower end portion 12b of the rod 12 is displaced downward in the rear side in the width direction of the door 2 than the lower end portion 12b of the rod 12 (corresponding to “the other side” in the claims). It is located above the point and faces the front-rear direction of the vehicle 1.

The extending portion 57 extends upward from the displacement restricting portion 53 to the latch mechanism 10. The extending portion 57 faces in the front-rear direction of the vehicle 1, the end on the vehicle interior side is bent toward the rear of the vehicle 1, and is formed along the outer shape of the latch mechanism 10.
A striker insertion hole 57 a is formed in the extension portion 57 at a position corresponding to the striker opening 43 of the latch mechanism 10. When the door body 5 is closed, the striker 9 enters the striker opening 43 through the inner panel opening 21a of the door inner panel 21 and the striker insertion hole 57a of the extending portion 57.

  Further, a bolt insertion hole 57b is formed in the extending portion 57. The extending portion 57 is disposed between the latch mechanism 10 and the door inner panel 21 and is fastened to the door inner panel 21 by being fastened together with the latch mechanism 10 by a bolt (not shown). Accordingly, the extending portion 57 functions as a patch that reinforces a fixing portion between the latch mechanism 10 and the door body 5 around the inner panel opening 21 a of the door inner panel 21.

  The peeling portion 59 is provided below the displacement restricting portion 53 and between the displacement restricting portion 53 and the connecting portion 51. The peeling portion 59 is twisted upward from the connection portion 51. The peeling portion 59 is not fixed to the door inner panel 21 and is disposed so as to contact the rear end inner surface of the door inner panel 21. Thereby, the peeling part 59 can be easily peeled from the door inner panel 21 (that is, the door main body 5) when an impact load is input from the outside and the door main body 5 is deformed.

  Here, the restricting member 50 of the present embodiment has a fragile portion 55 in the displacement restricting portion 53 between the extending portion 57 and the connecting portion 51. The fragile portion 55 is formed by providing a through hole 55 a that penetrates the displacement regulating portion 53. The fragile portion 55 has lower rigidity than other portions where the through hole 55a is not formed. Therefore, when the impact load is input from the outside and the door body 5 is deformed, the fragile portion 55 around the through hole 55a is easily deformed, so that deformation of the restricting member 50 can be induced.

(Function)
Then, the effect | action of 2 A of vehicle door structures mentioned above is demonstrated using drawing.
FIG. 6 is an explanatory diagram of the vehicle door structure 2A when an impact load is input from the outside. In FIG. 6, the outer panel surface 24 of the door outer panel 22 is shown in a transparent manner, and the outer shape of the outer panel surface 24 is indicated by a two-dot chain line. In addition, after the impact load is input from the outside, the deformed regulating member 50 is illustrated by a two-dot chain line.
As shown in FIG. 6, when an impact load is input from the outside toward the inside (LB direction in FIG. 6) along the left-right direction of the vehicle 1, the door outer panel 22 is deformed. At this time, a part of the stiffener 25 is deformed and moved to the inside of the door body 5 and a load is generated forward and downward with respect to the stiffener 25 (see arrow F1 in FIG. 6).

  At this time, the door outer panel 22 of the door body 5 moves toward the inside of the vehicle 1, but the grip portion 33 (see FIG. 1) of the outer handle 7 tends to stay in place due to inertial force. For this reason, the grip portion 33 of the outer handle 7 moves relative to the door outer panel 22 and rotates around the support shaft. As a result, the rod 12 tends to be displaced downward in conjunction with the rotation of the grip portion 33 of the outer handle 7 (see arrow F2 in FIG. 6).

Further, in the width direction of the door body 5, the restriction member 50 arranged so as to straddle the lower portion 12 b of the rod 12 has the upper end extended portion 57 fixed to the door inner panel 21 as the stiffener 25 moves. In this state, the connecting portion 51 moves forward and upward (see arrow F3 in FIG. 6).
At this time, the displacement restricting portion 53 between the connecting portion 51 and the extending portion 57 is a fragile portion 55 in which a through hole 55 a is formed to induce deformation of the restricting member 50. Further, below the displacement restricting portion 53 is a peeling portion 59 that can be peeled off from the door inner panel 21 of the door body 5. Therefore, the displacement restricting portion 53 has a lower portion than the lower end portion 12b of the rod 12 because the fragile portion 55 is easily deformed and the peeling portion 59 is peeled from the door inner panel 21 in response to the deformation of the stiffener 25. Be placed. Thereby, the displacement control part 53 contact | abuts with the lower end part 12b of the rod 12 which is going to be displaced below.

  Here, since the lower end portion 12b of the rod 12 is provided with the bent portion 13 that bends to the outside of the door body 5, a wide area for contacting the displacement regulating portion 53 at the lower end portion 12b of the rod 12 is secured. . As a result, the displacement restricting portion 53 reliably contacts the lower end portion 12b of the rod 12 and restricts the downward displacement of the rod 12, thereby preventing movement of the movable piece 41 of the latch mechanism 10 associated with the rod 12. it can. Accordingly, when an impact load is input from the outside of the vehicle 1, it is possible to prevent the engagement between the latch mechanism 10 of the door body 5 and the striker 9 (see FIG. 1) of the vehicle body 1A. 5 can be prevented from being opened.

  According to the vehicle door structure 2 </ b> A of the present embodiment, since the regulating member 50 that regulates the displacement of the rod 12 when the impact load is input from the outside of the vehicle 1, the impact load from the outside of the vehicle 1 is provided. Can be prevented from being disengaged from the door body 5 and the vehicle body 1A by restricting the rod 12 from being displaced downward. Therefore, the door body 5 can be prevented from being opened when an impact load is input from the outside of the vehicle 1.

  Further, since the regulating member 50 includes the connection portion 51 connected to the stiffener 25 of the door outer panel 22 in front of the lower end portion 12b of the rod 12, when an impact load is input from the outside of the vehicle 1, Corresponding to the deformation of the door outer panel 22, the connecting portion 51 moves. At this time, the displacement restricting portion 53 positioned behind the lower end portion 12 b of the rod 12 and above the lowest point of the lower end portion 12 b of the rod 12 moves along the lower end portion of the rod 12 as the connecting portion 51 moves. Move down 12b. Furthermore, since the restricting member 50 is disposed so as to straddle directly below the lower end portion 12 b of the rod 12, the displacement restricting portion 53 is reliably disposed below the lower end portion 12 b of the rod 12. Accordingly, the displacement restricting portion 53 can abut against the lower end portion 12b of the rod 12 to prevent the rod 12 from being displaced downward, so that the displacement regulating portion 53 is provided on the latch mechanism 10 provided on the door body 5 and the vehicle body 1A. It is possible to prevent the engagement with the striker 9 from being released. Therefore, the door body 5 can be prevented from being opened when an impact load is input from the outside of the vehicle 1.

  Further, by providing the bent portion 13 at the lower end portion 12b of the rod 12, when the impact load is input from the outside of the vehicle 1, it is possible to ensure a wide region where the displacement restricting portion 53 and the rod 12 abut. Accordingly, the lower end portion 12b of the rod 12 can come into contact with the displacement restricting portion 53 when an impact load is input from the outside of the vehicle 1 and the rod 12 is displaced downward.

  Further, since the connecting portion 51 of the restricting member 50 is connected to the stiffener 25 of the door outer panel 22, when the impact load is input from the outside of the vehicle 1 and the rod 12 comes into contact with the displacement restricting portion 53, the rod 12 Thus, the load applied to the displacement restricting portion 53 can be distributed to the stiffener 25 and the downward displacement of the rod 12 can be restricted.

  Further, since the regulating member 50 has an extending portion 57 that extends to the latch mechanism 10 and is fixed to the door inner panel 21 of the door body 5 together with the latch mechanism 10, an impact load is applied from the outside of the vehicle 1. When being input, the door body 5 can be prevented from being opened, and the fixing portion between the latch mechanism 10 and the door inner panel 21 of the door body 5 can be reinforced. Furthermore, the working time of the assembly process of the latch mechanism 10 and the regulating member 50 is shortened by fastening the latch mechanism 10 and the extending portion 57 of the regulating member 50 with bolts to the door inner panel 21 of the door body 5. it can.
