Description

The present invention
A door handle disposed outside the side door and the side door locking mechanism are linked via a linkage member to switch between the locked state in which the side door is locked to the closed side and the unlocked state in which the lock is released. The present invention relates to a vehicle door structure that is freely configured.

When another vehicle collides with the side of the vehicle (side collision), the side door arranged on the side of the vehicle is deformed, and the linkage member between the door handle provided on the side door and the side door locking mechanism is unlocked. There is a risk that the side door may be opened by being pulled to the side.
As means for preventing such unintentional unlocking, conventionally, there has been means for preventing the linking member from moving to the unlocking side by installing a counterweight (weight) on the upper part of the outer side handle.
However, the weight of the vehicle body was increased by the means using the counterweight. Moreover, since the size of the counterweight is large, the workability of the assembling work is deteriorated and the cost is greatly increased.
In addition to the above-described means, as disclosed in Patent Document 1, there is a technique in which a box-shaped unlocking restricting body is provided on a handle base fixed to the inside of an outer panel of a side door. In this technique, the handle base rotatably supports the door handle. Then, when the door is deformed and the handle base moves to the inside of the vehicle, the unlocking restricting body moves to the connecting member side and receives the connecting member in the notch of the unlocking restricting body, and is provided on the connecting member. The peripheral portion of the notch receives the protrusion from below, and prevents the linking member from descending to the unlocking side.
JP 2005-325569 A

According to the technique of Patent Document 1, since the lock release restricting body is provided on the handle base, in the structure in which the handle base and the linking member are separated from each other, the lock release restricting body becomes long and the rigidity of the lock release restricting body is increased.・ It was difficult to ensure strength.
The present invention has been made in view of the above circumstances, and its purpose is to reduce the number of parts, reduce the size, reduce the weight, reduce the manufacturing cost, and reduce the size of the assembly work. Workability can be improved, and the side door lock state can be prevented from switching to the unlocked state at the time of a side collision of the vehicle, and the side door can be reliably prevented from opening at the side collision. It is in the point which provides the door structure of the vehicle which can do.

The feature of the present invention is that

The distance from the protrusion part located in the said 1st position to the lower wall of the said recessed part can be shortened. As a result, when the automobile collides with the side in the locked state, the descending protrusion can be received early from below by the lower wall of the recess of the reinforcing member.
Thereby, it is possible to more reliably prevent the protruding portion from changing the position to the second position, and to avoid switching to the unlocked state, and to easily prevent the side door from being opened at the time of a side collision. be able to. (Claim 6)

According to the present invention,
The number of parts can be reduced, reduced in size, reduced in weight, and the manufacturing cost can be reduced, and the downsizing can improve the workability of the assembly work. Thus, it is possible to provide a vehicle door structure that can prevent the lock state from being switched to the unlocked state and can reliably prevent the side door from being opened at the time of a side collision.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1A and FIG. 1B are views (a view seen from the vehicle inner side W1) showing a part of the inside of the side door 1 of the automobile. As shown in this figure, a door handle mounting portion 4 disposed on the vehicle outer side W <b> 2 of the side door 1 is provided at the end of the side door 1 on the vehicle rear side.

Then, the door handle and the locking mechanism of the side door 1 located below the door handle Z1 are linked via a metal-made latch push rod 2 (corresponding to a linkage member) having a circular cross section along the vertical direction, The side door 1 is configured to be switchable between a locked state in which the side door 1 is locked to the closed side and an unlocked state in which the side door 1 is unlocked.
When in the locked state, the side door 1 cannot be opened, and when in the unlocked state, the side door 1 can be opened. The latch push rod 2 is configured to be raised and lowered, and as the occupant operates the door handle to switch from the locked state to the unlocked state, the latch push rod 2 descends and changes from the unlocked state to the locked state. As the switch is made, the latch push rod 2 rises.

  Further, a reinforcement 3 (corresponding to a reinforcing member) that reinforces the side door 1 is provided between the latch push rod 2 and the outer panel 15 of the side door 1 along the width direction (vehicle longitudinal direction) of the side door 1. In the vehicle width direction, the reinforcement 3 and the latch push rod 2 are crossed.

  The reinforcement 3 is provided over the entire width of the upper half of the side door 1 and is inclined upward and rearward so that the rear side of the vehicle is positioned upward. The end of the reinforcement 3 on the vehicle rear side is the door. It is close to the handle attachment portion 4 from below Z1. The inclination angle of the back of the reinforcement 3 is set small.

  As shown also in FIG. 4, a recess 5 is formed in the reinforcement 3 so as to be recessed in the vehicle outer side W2. That is, the reinforcement 3 is formed in a cross-sectional hat shape with the vehicle inner side W1 open, the side wall 6 of the reinforcement 3 whose plate surface faces the vehicle width direction, the upper wall 7 of the reinforcement 3 whose plate surface faces the vertical direction, and The recess 5 is formed with the lower wall 8.

  The upper wall 7 of the reinforcement 3 is inclined so as to be located at the upper side of the vehicle inner side W1, and is formed by an upper wall 7 and an upper flange 9 extending upward from the end of the vehicle inner side W1 of the upper wall 7. C is formed in an arc shape. On the other hand, the lower wall 8 of the reinforcement 3 is inclined so as to be positioned at the lower side Z1 as the vehicle inner side W1. The lower wall 8 and a lower flange 10 extending from the end of the vehicle inner side W1 of the lower wall 8 to the lower side Z1. The formed corner portion C is formed in an arc shape. The corner portion C formed by the side wall 6 and the upper wall 7 of the reinforcement 3 and the corner portion C formed by the side wall 6 and the lower wall 8 of the reinforcement 3 are also formed in an arc shape. Thereby, the concentration of force on the corner portion C of the reinforcement 3 is suppressed, and the durability of the reinforcement 3 is improved.

  Although not shown, the upper flange 9 is sandwiched between the outer panel 15 and the inner panel of the side door 1 and these are integrally welded, and the lower flange 10 is fixed to the outer panel 15 and the inner panel of the side door 1. These are sandwiched between and fixed together by welding.

As shown in FIG. 2, the latch push rod 2 has an upper end 2A connected to the door handle and a lower end 2B connected to the lock mechanism bent, and an intermediate portion 2C between the upper and lower ends is vertical. Are formed in a straight line.
At the center of the intermediate portion 2C of the latch push rod 2, a horizontally long rectangular metal plate 11 as viewed from the vehicle front-rear direction is welded and fixed in an orthogonal state so that the latch push rod 2 and the metal plate 11 are orthogonal to each other. One end of the vehicle outer side W2 of the metal plate 11 is formed as a protruding portion 12 protruding to the vehicle outer side W2.
That is, the metal plate 11 is welded and fixed to the latch push rod 2 so as to protrude from the latch push rod 2 to the vehicle outer side W2, and the protruding end portion of the metal plate 11 on the vehicle outer side W2 is configured as the protruding portion 12. . As described above, the latch push rod 2 is provided with the protruding portion 12 protruding to the vehicle outer side W2.

  As shown in FIG. 3, the metal plate 11 has a middle portion in the longitudinal direction bent in an arc shape. The arc-shaped portion 11A of the metal plate 11 is externally fitted to the intermediate portion 11C of the latch push rod 2 from the vehicle front side Fr and is welded and fixed. The plate thickness of the metal plate 11 is set to about 1/3 of the diameter of the latch push rod 2, and the width (length in the vertical direction) of the metal plate 11 is set to be larger than the diameter of the latch push rod 2. A pair of upper and lower corner portions C of the protruding portion 12 (one end portion of the vehicle outer side W2) of the metal plate 11 is formed in an arc shape.

As shown in FIG. 4, the protrusion 12 of the latch push rod 2 is positioned at the first position A1 facing the opening 5K of the recess 5 in the locked state, and the lower end 12K of the protrusion 12 is the lower wall of the recess 5. It is located higher than 8. Further, in the state where the protrusion 12 is located at the first position A1, the vertical center P of the protrusion 12 is positioned lower than the vertical center O of the recess 5 and the unlocked state The protrusion 12 is positioned at the second position A2 below the first position A1, and the lower end 12K of the protrusion 12 is positioned lower than the lower wall 8 of the recess 5, The arcuate corner C formed by the lower wall 8 and the lower flange 10 of the recess 5 is opposed to the inner side W1.
Since the protruding portion 12 of the latch push rod 2 is located on the vehicle inner side W1 with respect to the concave portion 5, the protruding portion 12 interferes with the lower wall 8 of the concave portion 5 when the latch push rod 2 is moved up and down by the operation of the occupant. There is nothing.

As shown in FIGS. 4 and 5, in the locked state, the vehicle collides sideways and the outer panel 15 receives a pressing force F toward the vehicle inner side W <b> 1, and the outer panel 16 is deformed to the vehicle inner side W <b> 1 to When the position is changed by pressing the inner side W1, the lower wall 8 of the recess 5 of the recess 3 receives the descending protrusion 12 from the lower side Z1, and the position change of the protrusion 12 to the second position A2 is prevented. However, it is configured to avoid switching to the unlocked state.
Thereby, it can prevent that the side door 1 at the time of a side collision opens. In the example of the side collision shown in FIG. 5, the protrusion 12 received from the lower wall 8 on the lower wall 8 of the recess 5 is positioned at the third position A3 above the second position A2 and above the second position A2 to the second position A2. The position change is prevented.

  In this case, the corner portion C formed by the lower wall 8 and the lower flange 10 extending downward Z1 from the end of the vehicle inner side W1 of the lower wall 8 is formed in an arc shape, and further, the metal plate 11 Since the pair of upper and lower corners C of the protruding portion 12 (one end portion of the vehicle outer side W2) is formed in an arc shape, the protruding portion 12 can be easily received in the recessed portion 5 of the reinforcement 3, The lower wall 8 can easily receive the protrusion 12 from the lower side Z1.

Further, since the reinforcement 3 is intended to reinforce the side door 1, the reinforcement 3 has sufficient strength against deformation. The portion 12 can be reliably received from the lower side Z <b> 1 by the lower wall 8 of the recess 5 of the reinforcement 3.
As a new member, the metal plate 11 is simply welded and fixed to the latch push rod 2, so that it is possible to further reduce the number of parts, reduce the size, reduce the weight, and reduce the manufacturing cost.
