Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an automobile door, and more particularly to the structure of a back door.

(Prior art) In recent years, there has been a strong tendency to use automobiles not only for practical purposes but also for leisure purposes.In order to respond to the tendency of young people in particular to use automobiles for leisure purposes, vehicles with sunroofs with an opening in the roof, vehicles with back doors, etc. has been commercialized. However, conventional models are structured so that the back doors must be closed when driving, so even if the sunroof is opened, it is not possible to enjoy the feeling of openness comparable to that of an open car. . Therefore, the present inventors attempted to diversify the opening/closing manner of the back door and arrived at the present invention. It should be noted that a structure in which the trunk lid is divided into an outer lid and an inner lid so that the lid can be opened in two ways, large and small, is known as described in Japanese Utility Model Application Publication No. 101666/1982. There is still no known device that attempts to diversify the opening/closing manner.

(Object of the invention) The present invention has been made in view of the above points, and
The purpose of this is to configure the back door so that its opening/closing manner can be changed in a variety of ways, thereby corresponding to the purpose of use as a cashier.

(Structure of the Invention) According to the present invention, a back door that covers a rear opening of a vehicle body is constituted by a window frame portion formed in a rectangular shape and an opening/closing door portion that covers an opening portion of the window frame portion. The upper end of the window frame frame is detachably attached to the vehicle body, and the lower end thereof is hinged to the vehicle body so that the window frame frame can be rotated toward the inside of the vehicle interior, and the opening/closing door portion The upper end side is hinged to the window frame so that it can be opened and closed freely, while a fixing member is provided on the inside of the vehicle interior to support and fix the window frame when the back door rotates toward the interior of the vehicle. This makes it possible to open the back door as a whole to the inside of the vehicle interior, and also to make it possible to open and close only the opening/closing door section, thereby diversifying the manner in which the back door can be opened and closed. be.

(Example) Hereinafter, an automobile door structure according to an example of the present invention will be described with reference to the accompanying drawings.

The automobile of this embodiment has a roof panel 2 of a vehicle body 1.
It is of a sunroof type having an opening 3 at the rear, and a back door 5 is attached to the rear opening 4 so as to be openable and closable.

As shown in FIG. 2, the back door 5 includes a window frame part 6 formed into a rectangular shape so as to be able to come into contact with the edge of the opening 4 from below, and the window frame frame part 6.
and an opening/closing door section 8 made of transparent glass that covers the opening section 7 of the door. The opening/closing door section 8 is configured to abut against the window frame section 6 from above.

As shown in FIG. 2, the lower end side 6b of the window frame portion 6 is connected to a rear panel 9 constituting the lower edge of the rear opening 4 by hinges 10, 10 so as to be rotatable in an arc. , the upper end side 6a of the window frame portion 6 has a rear opening 4 as shown in FIG.
It is removably fixed to the roof panel 2 constituting the upper edge of the roof panel 2 with fixing devices, in this embodiment bolts 11, 11. Reference numeral 12 denotes a rubber seal for maintaining watertightness of the contact surface between the edge of the rear opening 4 and the window frame portion 6.

In other words, the window frame part 6 has hinges 10, 10
It is said that it can be freely rotated towards the inside of the vehicle using the fulcrum as a fulcrum.

Further, as shown in FIGS. 2 and 3, the upper end side 8a of the opening/closing door section 8 is connected to the upper end side 6a of the window frame section 6 by hinges 13, 13 so as to be able to open and close upward. There is. The lower end side 8b of the opening/closing door portion 8 is configured to be locked with respect to the vehicle body 1 by a locking mechanism (not shown). Furthermore, this opening/closing door part 8 has stays 1 fixed to both sides thereof and both sides of the window frame part 6.
Dampers 15, 15 interposed between 4, 14
It is configured such that it can be maintained in an open state by. Reference numeral 16 denotes a rubber seal for maintaining watertightness of the contact surfaces between the window frame portion 6 and the opening/closing door portion 8.

Further, engaging protrusions 17, 17 are provided protrudingly on both sides of the window frame portion 6, while a recess 19 is formed in the seat back 18 of the rear seat on the inside of the vehicle interior to engage the engaging protrusions 17. A fixing member 20 is provided. The engaging protrusion 17 and the recess 19 constitute a fixing device 21, which allows the back door 5 to be held in a substantially horizontal state.

Therefore, this backdoor can be used in the following three ways.

(a) With the window frame part 6 in the closed state, open the opening/closing door part 8 upward (see Fig. 4, a). In this case, it is a normal usage mode.

(b) With the opening/closing door section 8 in the closed state, remove the fixtures 11, 11, and open the window frame section 6, that is, the back door 5, using the hinges 10, 10 as fulcrums.
is rotated in an arc toward the interior of the vehicle, and held in a substantially horizontal state by the fixing device 21 (see FIG. 4B). When driving in this state, combined with the sunroof, you can enjoy a feeling of openness similar to that of a fully open car.

(c) From the state of (b) above, only the opening/closing door section 8 is opened upward (see Fig. 4, c). This makes it easy to take items in and out of the cargo room.

(Effects of the Invention) As described above, according to the present invention, the back door is constituted by a window frame portion and an opening/closing door portion that covers the opening of the window frame portion, and the window frame portion or the door portion covers the opening of the window frame portion. Since the opening/closing door section can be opened and closed individually or both together, it is possible to diversify the opening/closing manner of the back door.Furthermore, when the window frame section is rotated toward the inside of the vehicle, etc.
It is also possible to drive the vehicle as it is, providing a sense of openness comparable to that of a fully convertible car, which will greatly contribute to improving the marketability of automobiles.
