Description

[Detailed description of the invention] This invention relates to a rear frame mounting structure for doors with removable door frames, and is used in automobile doors in which a door frame is removably attached to a door body incorporating an elevating door glass. ,
The present invention relates to a structure that allows the rear frame to be mounted with good workability and high mounting rigidity.

For example, some four-wheel drive vehicles designed to be suitable for off-road driving have a canopy covering the cabin, a front window that can be folded forward, and a door frame that can be attached or removed. By removing the top, tilting the front window forward, and removing the door frame, some cars become fully open cars with nothing separating the upper part of the cabin from the outside air.

As a method for making the door of such a car into a removable door frame type, for example,
As shown in Publication No. 56-51622,
It is known that a simple door frame is constructed by simply bending a steel pipe or steel bar into an inverted U shape and a canopy with a transparent window is attached to the lower door body in a removable manner. . However, with a door frame like this, which is just a canopy stretched over the frame, it is virtually impossible to attach a weather strip to the door frame to seal between the door opening and the door. There are problems in that the seal between the window and the door cannot be completely sealed, and the window cannot be opened easily. For this reason, recently, the concept of making such a door frame removable from the door body has been changed to a normal door, i.e.
Plans are being made to apply this method to a door in which a door frame with a guide groove for slidingly guiding the door glass is attached to a door body in which an elevating door glass is incorporated.

For doors with normal door frames, high mounting rigidity of the door frame to the door body is achieved by welding the lower ends of both the front and rear frames of the door frame while deeply inserted into the door body. There is. If the mounting rigidity of the door frame to the door body is not increased, the door weather strip attached to the outer periphery of the door frame will not adhere to the door opening of the vehicle body sufficiently, making it difficult to maintain airtightness within the vehicle interior. In addition, it becomes impossible to avoid so-called suction noise and vibration caused by negative pressure on the outside surface of the window during high-speed driving.

For this reason, when the door frame is made removable, the mounting structure of the door frame to the door body can ensure the above-mentioned mounting rigidity when the door frame is attached, and the door frame can be easily attached and detached. It is necessary to simultaneously satisfy these contradictory issues.

The present invention was devised under the above circumstances, and among the two leg-shaped frames of the door frame, namely the front frame and the rear frame, the rear frame in particular has a high height relative to the door body. It is an object of the present invention to provide a mounting structure that can ensure mounting rigidity and also allows easy attachment and detachment work.

In order to achieve this purpose, the rear frame mounting structure of the door frame removable door of the present invention employs the following configuration.

That is, in the rear frame mounting structure of the present invention, the rear frame of the door frame is provided with an insertion portion extending downward from the lower end thereof, and near the lower end, the insertion portion is provided with an insertion portion extending inward in the vehicle width direction from the rear frame. A bracket that wraps around the passenger compartment side side of the door inner panel of the door body and embraces the door body is fixed, and the insertion part is inserted into the rear end of the upper edge of the door body to support it. The insertion opening has a receiving surface that receives the side surface of the bracket on the side surface of the door inner panel facing the passenger compartment, and the insertion part inserted into the insertion opening is screwed into the rear surface of the door inner panel. In addition, the bracket is screwed over the receiving surface of the door inner panel.

According to this configuration, first, when the insertion portion of the rear frame is inserted into the insertion opening of the door body, the position of the rear frame with respect to the door body is accurately determined, so there is no difficulty in positioning. Also,
Since the insertion portion of the rear frame and the door inner panel are fixed with screws, the work is easy. Further, since not only the insertion portion and the door inner panel are fixed, but also the bracket fixed to the rear frame and the door inner panel are fixed, the rigidity of the door frame in the attached state is sufficient. Moreover, in the present invention, the bracket fixed to the rear frame is branched inward in the vehicle width direction from the rear frame and wrapped around the side surface of the door inner panel on the passenger compartment side, and the bracket is attached to the door inner panel while the door body is hugged. Screw it to the panel.
Therefore, the screw-fastening position of the bracket is slightly shifted toward the passenger compartment from the screw-fastening position of the insertion part, and the rear frame is rigidly connected to the door inner panel at two points separated in the vehicle width direction. Therefore, high mounting rigidity can be obtained. In particular, it is possible to increase the bonding strength of the door frame in the vehicle width direction, which tends to decrease. Furthermore, since the door body is held in from the outside (interior side) by an arm-shaped bracket that is fixed to the rear frame, and the bracket is screwed at this holding part, the door may be damaged by vibrations caused by driving, etc. Problems such as the upper part of the frame vibrating or the entire door frame collapsing can be prevented, and the strength of the bond between the door frame and the door body is significantly improved. Moreover, high bonding strength can be maintained for a long time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the entirety of a door body 1 and a door frame 2 detachably attached thereto.
The door body 1 is formed by pasting an outer panel and an inner panel together to form an internal space,

It has a gate-shaped configuration consisting of a front frame 4 extending diagonally, a horizontal frame 5 extending in the front-rear direction, and a rear frame 6 extending substantially vertically.
The door frame 2 is constructed by inserting screws 9 into the door frame 2 such that the bracket 7 fixed to the lower part of the front frame 4 overlaps the door corner piece 8 formed upwardly at the front end of the upper edge of the door body 1 from the inside. At the same time, the lower end of the rear frame 6 is inserted into the rear end of the upper edge of the door body 1 and fixed with screws 10, and a bracket 11 branched from near the lower end of the rear frame 6 is attached. It is removably attached by fixing it to the support surface 32 formed on the upper part of the side surface of the vehicle interior side of the inner panel 18 of the door body 1 using screws 14.

The details of the mounting structure of the rear frame 6, which is the main part of the present invention, are shown in FIG. 2 and subsequent figures.

As the cross section of the rear frame 6 is shown in FIG. 2, the rear frame 6 is a member having a guide groove 15 for sliding the elevating glass on its inside and a flange portion 16 on its outside. A glass run is fitted into the sliding guide groove 15, and
A weather strip is attached to the outer surface or the inner surface of the flange portion 16. An insertion portion 17 having a U-shaped cross section and extending continuously from the rear frame 6 is fixed to the lower end portion of the rear frame 6 by welding. In addition, near the lower end of the rear wall of this insertion portion 17, this is attached to a door inner panel 18.
A screw hole 19 into which a screw 10 is screwed is formed by burring or the like.

Further, near the lower end of the rear frame 6, a bracket 11 is welded which branches inward in the vehicle width direction, wraps around the side surface of the door inner panel 18 on the passenger compartment side, and embraces the door body 1 from the outside. Fixed. In the illustrated example, the bracket 11 is a U-shaped base member 1 that holds the inner corner portion 6a of the rear frame 6 over a predetermined length above and below.
1a, and a planar abutment plate portion 21 extending downward while branching inward in the vehicle width direction from the base member 11a and overlapping with a support surface 32 formed on a door inner panel 18, which will be described later. It is constructed by welding together a branch member 11b formed from sheet metal,
The base member 11a is fitted and welded to the inner corner portion 6a of the rear frame. A reinforcing plate 23 is welded and fixed to the abutting plate portion 21, and two screw holes 24, upper and lower, are bored therein. In addition, the branch member 11b is provided with ribs 25 as appropriate.
By forming the recesses 26, the strength against bending is increased.

On the other hand, an internal space 29 that can accommodate the door glass 28 and a mechanism for raising and lowering the door inner panel 18 and the door outer panel 27, etc.
As shown in FIG. 3, the rear end of the upper edge of the door body 1 is welded to form
An insertion opening 30 into which the insertion portion 17 of the rear frame 6 as shown in FIG. 2 can be inserted is formed. The insertion opening 30 can be formed by bending the rear upper part of the door inner panel 18 into a predetermined shape. and a predetermined distance from the upper end of the rear surface portion 18a of the inner panel 18 extending downward from the rear edge 30a of the insertion opening 30;
That is, a screw hole 31 is formed at a position corresponding to the screw hole 19 in the vehicle width direction at a distance corresponding to the distance from the upper end of the insertion part 17 of the rear frame 6 to the screw hole 19, and A planar support surface 32 for receiving the abutting plate part 21 of the bracket 11 is formed at the rearward upper part of the side surface 18b on the side of the vehicle compartment 18, and a screw hole formed in the abutting plate part 21 is formed therein. Two screw holes 33, upper and lower, corresponding to the holes 24 are made.
In addition, as shown in FIG. 3, the support surface 32 of the door inner panel 18 or the rear surface portion 18
A reinforcement 34 formed from a sheet metal is welded to the back surface of the door inner panel 18 along the inner surface of the inner panel in this area, thereby increasing the strength of the door inner panel 18 near the rear upper side. Of course, this reinforcement 34 includes the door inner panel 18.
Screw through holes 35 and 36 corresponding to the screw through holes 31 and 33 formed in the support surface 32 are bored, and a nut 37 is welded to the back side of the screw through hole 36 located on the inner surface of the support surface 32. It is fixed.

FIG. 4 is an external view showing a state in which the rear frame 6 shown in FIG. 2 is attached to the door body 1 shown in FIG. 3. The rear frame 6 is attached to the door body 1 as follows.

That is, first, insert the insertion portion 17 of the rear frame 6 into the insertion opening 30 on the door body 1 side until the lower end of the rear frame 6 comes into contact with the edge of the insertion opening 30. At this time, the contact plate portion 2 of the bracket 11
1 hits the support surface 32 of the door inner panel 18, even if there is some play between the insertion port 30 and the insertion portion 17, the angle of the rear frame 6 in the vehicle width direction is regulated as specified. Ru. Next, as shown in FIG. 6, screw the screw 10 inserted through the screw hole 31 into the screw hole 19 of the insertion part 17 of the rear frame 6, and as shown in FIG. The screw 14 inserted through the hole 24 is screwed into the nut 37 on the back surface of the reinforcement 34 through the screw through hole 33 of the support surface 32. The rear frame 6 installed in this way ends up with its insertion part 17,
Since the contact plate portion 21 of the bracket 11 that branches from this is rigidly contacted to the door body at two points separated by a predetermined distance in the vehicle width direction, the rear frame 6 has extremely high rigidity against the force that attempts to bend the rear frame 6 in the vehicle width direction. It gets expensive. Furthermore, when installing the door frame 2, the door body 1 is held in the bracket 11 from the outside, and screws are secured at this holding part, so that the upper part of the door frame may vibrate due to vibrations caused by running, etc. Problems such as the entire frame 2 shaking can be prevented, and the mounting rigidity of the door frame is significantly improved.

As explained above, in the front frame mounting structure of the door frame detachable door according to the present invention, the rear frame can be easily attached and detached, and the bending rigidity of the rear frame in the attached state is extremely strong. , it is possible to maintain a high degree of sealing between the weather strip attached to the outer circumference of the frame and the door opening of the vehicle body, and has the excellent effect of extremely reducing frame vibration and suction noise when driving at high speeds. have.

It goes without saying that the scope of the present invention is not limited to the above-described embodiments, and in particular, the specific shape of the bracket that is branched and fixed to the rear frame can be modified in various ways.
