Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a trunk compartment of an automobile.

(Prior Art) The general structure of a trunk room of an automobile will be explained based on FIG. 7, which is a longitudinal cross-sectional view.
0, the lower surface is made up of a trunk pan 101 made of iron plate, the rear surface is made up of a toe board 102 made of iron plate, and the front side is made up of a bulkhead made of iron plate (not shown), and these members are welded or bolted to the upper frame 103 or side frame 104 of the vehicle body. This creates a box-like trunk room with an open top.

(Problems to be Solved by the Invention) In the conventional trunk room structure described above, a plurality of iron plates are assembled to form one trunk room, so in order to obtain airtightness, the joints with the frame, etc. must be sealed with a sealing material 105, and forming and assembling each steel plate is troublesome and heavy, and the wheel house 100
It is necessary to apply an undercoat to the outer surface of the trunk compartment and the lower surface of the trunk pan 101, and since it is made of a plurality of iron plates, it is difficult to form a continuous shape around the top opening of the trunk compartment, and the sealing material 10 is applied over the entire opening circumference.
6 is difficult to install, and because it is made of iron plate, it is prone to rust, and there are problems such as increased noise in the trunk room.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a box body whose entire rear surface, both side surfaces and bottom surfaces are integrally molded of resin, and whose top surface is open, between the left and right vehicle body frames. By placing and fixing the vehicle from above in the space formed by the vehicle, it can be used as a trunk room.

(Example) Examples of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the front frame structure of a midship engine vehicle or a rear engine vehicle that has a trunk room at the front of the vehicle body.
The front frame 1 extends forward from the left and right ends of the dash board 2 with upper frames 3, 3,
Side frames 4, 4 are placed below the upper frames 3, 3, and the front ends of the upper frames 3 and side frames 4 are welded to the bulk head 5, and the space between the left and right side frames 4, 4 is are connected by a cross frame 6, and each frame forms a space S having a width approximately equal to the width of the vehicle at the front of the vehicle body.

Then, a box body 7 defining a trunk room is placed in the space S from above and fixed to each frame with screws or the like.

This box body 7 is integrally molded from olefin resin such as polypropylene or polyethylene.
The details are as shown in FIG. 2 which is an overall perspective view and FIG. 3 which shows the installed state, the front surface 8, the rear surface 9,
Left and right side surfaces 10, 10 and a lower surface 11 are integrally and continuously formed, and the upper surface is an opening 12.

A recess 14 as a shroud for housing the radiator fan 13 is formed in the front face 8,
Both side walls 14a, 14a of this recess 14 have tapered surfaces facing inward, and a hole 15 for mounting the motor of the fan 13 is formed in the front wall 14b of the recess 14. A pair of left and right fins 16, 16 are provided at the lower end of the recess 14, and these fins 16, 16 are tapered toward the rear, so that it functions as a nozzle. The flow velocity on the downstream side of the fan 13 is increased to improve the sweep effect.

The side surface 10 of the box body 7 also serves as a wheel house, and the side surface 10 is provided with a relief part 17 of the upper frame 3 and a side frame 4 so that the box body 7 can be placed from above and removed from above. A relief part 18 is formed. Then, a downwardly hanging piece 19 is formed along the upper edge of the relief part 18 as shown in FIG.
covers the upper end flange portion 4a of the side frame 4 to protect it from damage caused by chipping.

In addition, the rear surface 9 of the box body 7 has a left half 9a bulging out rearward to form a space 20 on the right side for storing auxiliary equipment such as a brake master cylinder or a wiper motor, and also on the left half 9a. A recess 21 is formed for storing auxiliary equipment.

Further, a flange portion 22 is formed outwardly around the entire circumference of the opening 12 of the box body 7,
The projecting piece 2 extends further outward from the flange portion 22.
3 is provided, and a mounting hole 24 for a bolt etc. is provided in this protrusion 23.
is formed. As shown in FIG. 3, the box body 7 is fastened together with the side body 25 to the upper frame 3 via the cushioning material 26. Further, an upwardly protruding strip 27 is formed on the upper surface of the flange portion 22 over the entire circumference, and a sealing member 28 is fitted onto this protruding strip 27 as shown in FIG. 5 to provide a seal when the lid 29 is closed. I'm trying to improve my sexuality. The seal member 28 may be attached directly to the upper surface of the flange portion 22 without providing the protrusion 27. In addition, the lower surface 1 of the box body 7
1 is slightly inclined toward the center, and a grommet 30 for draining water is provided at the center.

FIG. 6 is an overall perspective view of the box body 7 showing another embodiment.
A cowl panel 32 in which an air inlet 31 is formed extends rearward from the rear upper end of the vehicle, thereby reducing the number of parts.

(Effects of the Invention) As explained above, according to the present invention, the box body that defines the trunk room is integrally molded from resin, so rust does not occur compared to the conventional method, the weight is reduced, and the number of manufacturing steps is reduced. In particular, in the past, multiple iron plates were joined together, which resulted in poor sealing performance, but by making it an integrally molded resin product as in the present invention, the sealing performance was improved. In addition, since it is molded from resin, it has more freedom in shape, can expand trunk capacity, can be washed with water, makes less noise, and is easy to replace, among other benefits.
