[Detailed description of the invention] The present invention relates to a vehicle door device.

In a conventional vehicle door device, one end of the door is generally pivotally attached to the vehicle body via a vertically disposed hinge or the like, and a locking portion is provided at the end of the door.

However, such conventional door devices have a problem in that the support at the locking section does not work effectively against body vibrations and the like, and the strength of the door section of the vehicle is significantly reduced.

In view of these circumstances, a method has been proposed for improving the restraint of the door by pin-coupling the door and the vehicle body when the door is closed.

This means reduces the burden on the door hinge by supporting the weight of the door on the J11 body via the pin,
The purpose is to maintain the door opening/closing mechanism in good condition.

That is, the conventional pin connection is 11! of the door! In order to allow movement in the width direction, the tvI is controlled by a cylindrical parallel pin formed to have the same cross section up to one end, and a cylindrical sleeve 7 attached to the vehicle body.

When using parallel pins, the fit between the parallel pin and the sleeve must be tight in order to securely restrain the door to the vehicle body, and when designed in this way, the feeling of opening and closing the door The problem is that the door cannot be opened and closed smoothly.

In addition, in order to improve the opening/closing feeling of the door, if the fitting between the parallel pin and the pin holder is made loose, the door will be supported by the body at tl, but when the vehicle is running, etc. However, there is a problem in that the bending moment in the vehicle length direction generated in the vehicle body due to engine vibration does not work effectively, and vehicle body vibration occurs in the vehicle body.

9 and supports radial loads.

In one case with such a conventional shaft support, it is difficult to work so as not to create gaps in the vertical and radial directions. Since the clearance and the clearance in the radial direction are not uniform, the 1st round 21 [is changed and the 1st ζ is also changed to eliminate the clearance. (= Because there is a gap left, the play in the J5 shaft part is not erased and the body of the door J.
There is a problem that the restraint condition of \ becomes loose, and car body vibration occurs when Jl 1 car is running.

The present invention aims to solve these problems, and therefore provides a reinforced door device for a vehicle that can reduce vehicle body vibration by improving the door restraint state and increasing the vehicle body strength. The purpose is to

Closing J: Since the needle bearing 25 or the clearance in the Ranoal direction will close the gap, the door 1 will be restrained by the 111 body B.

Therefore, as shown in FIG. 6, the door 1 forms a truss with the two door hinges 2, 2 and the taper pin 3, and the bending static rigidity of the vehicle body I3 becomes -1.

This increased rigidity allows for a tight fit.J:111 equipped with a reinforced door device with parallel pins designed to
A bending HP stiffness almost equal to that of the body can be obtained.

In addition, when the door 1 is opened and closed, a distorted view can be created (), so a tight compliment can be achieved, and the rigidity of the car I+13 due to the door 1 is increased.

Furthermore, when the vehicle is running at 117, the vibration in the mode shown by the two-dot chain line in the PtS1 diagram occurs in the lateral direction of the F” F” vehicle.
This is caused by the vibration of the νi engine IΣ, while the restraint on the vehicle body I-3 by the pin j) of the door 1
When the number 3 is opened, the rigidity is decreased by -1, so the displacement of the J11 due to the influence from the engine E is reduced, and the integral vibration of the J11 becomes more severe as shown in FIG.

Further, depending on the position of the taper pin 3, vibrations can be reduced in other directions as well, such as the width of the vehicle.

In other words, Fig. 7 shows the steering wheel response (V/F) when the tip of the vehicle body frame is vibrated in an upward direction.
The dashed dotted line (see symbol a) shows the case with a pillarless without a pin, and the broken Al11 (see the symbol a) shows the case with a pillarless with parallel pins designed to fit tightly.
Tenkasu (see code C) shows the case of a pillarless using the taper pin of the present invention.

As shown in the figure, when a taper pin is used, the vibration reduction effect is almost the same as when using a flat 16' taper pin that is designed to fit tightly. Effectively reduces the vibration of the car 14N B while maintaining the ring.

Note that the shape of the pin may be a wedge shape, and if it is tapered in the vertical J direction, the pin can be tightly fitted and supported in the vertical direction, thereby reducing the vibration of the J body B in the vertical direction. It can be effectively reduced.

Moreover, the arrangement positions of the pin and the fitting mechanism may be reversed,
In this case, the fitting side is fixed to the edge of the door, and the pin is erected on the outer surface of the vehicle body facing the edge of the door.

Further, the force mechanism of the slide block 7 may be configured to supply hydraulic air pressure or the like to the opening between the slide block 7 and the bottom portion 5a of the sleeve 5.
