DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile having a door supported on a vehicle body so as to be openable and closable.

[0002]

2. Description of the Related Art Various types of doors are provided on a vehicle body of an automobile. Such doors are generally supported by doors via hinges, and when the doors are closed, the doors are attached to the vehicle body by a lock device. Locked. The door in the closed state is fixed to the vehicle body by the hinge and the lock device, but the ratio of the fixed portion to the entire door is very small.

On the other hand, when an external force acts on the vehicle body with the door closed as described above from outside the door,
It is necessary to prevent the door from being significantly bent and deformed toward the interior of the vehicle due to the external force, and to ensure the safety of the vehicle.
However, as described above, the fixing part that fixes the door to the vehicle body is a very small part of the entire door, so if this state is left as it is, the door to which external force is applied will shift with respect to the vehicle body However, it is easy to be permanently deformed in a direction to be displaced toward the vehicle interior.

Therefore, conventionally, the rigidity of the door itself has been increased, and the strength of the hinge and the lock device has been increased. When an external force acts on the door, the rigidity of the door itself and the hinge for fixing the door to the vehicle body have been improved. The locking device prevents the door from being bent and deformed significantly toward the interior of the vehicle. By setting the strength of the hinge and the lock device large, the door to which external force is applied is strongly supported on the vehicle body, and the door is prevented from moving relative to the vehicle body,
This prevented large bending deformation toward the vehicle interior.

However, as described above, in order to increase the rigidity of the door itself and to increase the strength of the locking device and the hinge, it is necessary to set the plate thickness and size of each of the constituent elements to be large. The disadvantage of increasing the overall weight and increasing the cost is inevitable. The amount of permanent deformation of the door when external force acts can be reliably suppressed,
In addition, an automobile structure that can reduce weight and cost is most desirable.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made based on the above recognition.
Even if the strength of the door itself or a hinge or a lock device for fixing the door to the vehicle body is set smaller than that of the conventional vehicle, it is possible to provide an automobile that can reliably prevent the door from being greatly bent and deformed toward the interior of the vehicle when an external force is applied. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings, and the above-mentioned conventional disadvantages will be more specifically clarified with reference to the drawings.

FIG. 1 is a side view showing an automobile according to an embodiment of the present invention, and FIG. 2 is an enlarged sectional view taken along line II-II of FIG.
A door 3 is supported on the vehicle body 1 of the automobile shown here via a pair of upper and lower hinges 2 and 2 so as to be openable and closable. By closing the door 3 as shown in FIGS.
The door opening 4 (see FIG. 3) of the vehicle body 1 can be closed. At this time, the door 3 is immovably locked to the vehicle body 1 by the lock device 5 shown in FIG. In addition, the door opening 4 is opened by rotating the door 3 with the hinges 2 and 2 as fulcrums, from which the occupant can enter and exit the vehicle interior.

FIG. 3 is a perspective view showing a lower portion of the vehicle body 1 when the door 2 is opened, that is, a vehicle body portion indicated by reference numeral III in FIG. As can be seen from FIG. 2 and FIG.
A floor panel 7 forming a floor surface of the vehicle interior 6, a rocker panel 8 forming a skeleton at a lower side portion of the vehicle body 1,
The vehicle includes a center pillar 9 and the like constituting a skeleton of a vehicle body side portion, and the above-described door opening 4 is defined by the rocker panel 8 and the center pillar 9 and the like.

The rocker panel 8 is a rocker inner panel 8.
a, and located outside of the panel 8a in the vehicle width direction,
And a rocker outer panel 8b integrally fixed to the rocker inner panel 8a, and these panels 8a, 8b
Extends in the front-rear direction of the vehicle body 1. Also the center pillar 9
Are a pillar inner panel 9a and a pillar outer panel 9 which extend in the vertical direction of the vehicle body 1 and are integrally fixed to each other.
b. The pillar outer panel 9b is located outside the pillar inner panel 9a in the vehicle width direction. In the example shown in FIGS. 2 and 3, the rocker inner panel 8a and the pillar inner panel 9a are formed by an integrated body inner panel 10a, and the rocker outer panel 8b and the pillar outer panel 9b are also formed by an integrated body outer panel 10b. The center pillar 9
Is provided with a reinforcing panel 11 whose lower part extends to the inside of the rocker panel 8. The reinforcing panel 11 has front and rear flange portions sandwiched between front and rear mating flange portions 12a and 12b of the pillar inner panel 9a and the pillar outer panel 9b, and these are integrally fixed by spot welding. Reinforcement panel 11
Is integrated with the rocker outer panel 8b by spot welding. By providing such a reinforcing panel 11, the rigidity of the vehicle body 1 can be further increased. The floor panel 7 has a vehicle width direction outer edge 7a fixed to the rocker inner panel 8a by spot welding.

On the other hand, as shown in FIG. 4, the door 3 has a door inner panel 13a which is located on the inner side in the vehicle width direction with the door 3 closed as shown in FIG. Has a door outer panel 13b located at
These panels 13a and 13b have their peripheral edges integrated by hemming to define a space between the panels 13a and 13b.

When the door 3 is closed as shown in FIG. 1, the door 3 is fixed to the vehicle body 1 at the center of rotation by two upper and lower hinges 2 and 2 and at the free end thereof. The part is fixed to the vehicle body 1 by one lock device 5. As described above, there are very few portions where the door 3 is fixed to the vehicle body 1, and conversely, there are many door portions that are not fixed to the vehicle body 1. Accordingly, if a large external force acts on the door 3 from outside as shown by an arrow F in FIG. 2, the door 3 may be greatly bent and deformed toward the vehicle interior 6. There is.

Therefore, conventionally, as described above, the thickness of the door inner panel 13a and the door outer panel 13b constituting the door 3 is set to be large to increase their rigidity, and the hinges 2, 2 and the lock device 5 are provided. The thickness and size of each component are set to be large to increase the strength. In this way, when an external force F acts on the door 3 from the outside, the door itself is prevented from being bent and deformed, and the hinges 2 and 2 and the lock device 5 having high strength are used to move the door 3 to the vehicle body 1. By firmly supporting the door 3, the door 3 is prevented from moving relative to the vehicle body 1, and the door 3 is prevented from being largely bent and deformed toward the vehicle interior 6. However, as described above, according to the conventional countermeasure, the disadvantage that the weight and cost of the vehicle increase is inevitable.

Therefore, in the automobile of this embodiment, as shown in FIG. 2 and FIG. 4, a pin 14 protrudes from the door inner panel 13a of the door 3, and the door 3 is closed on the vehicle body 1 as shown in FIG. At this time, a hole 15 into which the pin 14 is fitted is formed. In the illustrated example, the head 14 a
The head part 14a is fixed to the door inner panel 13a, and the shaft part 14b extends through a hole formed in the door inner panel 13a.

The above-mentioned pin 14 is preferably arranged at a position as far as possible from the hinges 2 and 2 and the lock device 5, and is provided below the free end portion of the door 3 in this example. The hole 15 of the vehicle body 1 is formed at a position corresponding to the pin 14 when the door 3 is closed. In this example, the hole 15 penetrates the body outer panel 10b and the reinforcing panel 11 inside the body outer panel 10b. It is formed as a hole.

In this embodiment, the shaft 14b of the pin 14
For example, a cylindrical collar 17 made of a rigid body such as a steel plate is fixedly fitted with a cushion member 16 made of an elastic material such as rubber or soft synthetic resin, and surrounds a hole 15 formed in the vehicle body 1. In the example shown in the figure, the vehicle body 1 is integrally fixed to the inner surface of the reinforcing panel 11 by welding.

Further, in this embodiment, the hole 15 is closed by a sealing cap 18 made of, for example, a synthetic resin, and the cap 18 is formed substantially in a cup shape.
The edge portion 18a is fixed to the body outer panel 10b by, for example, an adhesive, and the central portion 18b is fitted in a state of protruding into the hole 15 from the outside to the inside of the vehicle. When the door 3 is closed, the pin 14 has its shaft portion 14 b inserted into the sealing cap 18 inserted into the hole 15.
Into the central portion 18b of the. Thus, the cap 1
Reference numeral 8 is arranged at a position which does not hinder the fitting of the pin 14 into the hole 15.

When a large external force F acts on the door 3 from the outside with the door 3 closed as shown in FIG. 2, the door 3 will bend and deform toward the vehicle interior 6. And However, at this time, the door 3 is connected to the hinges 2, 2
Since the door 3 is not only fixed to the vehicle body 1 by the lock device 5 but also connected to the vehicle body 1 via the pin 14, the door 3 is also fixed to the vehicle body 1 by the pin 14. Therefore, the door 3 receiving the external force F is prevented from being largely bent and deformed toward the vehicle interior 6. Door 3
When an external force F is applied to the vehicle body 1, the pin 3 fitted in the hole 15 of the vehicle body 1 prevents the door 3 from moving relative to the vehicle body 1, and the door 3 is firmly attached to the vehicle body 1. Support it.

As described above, when the external force F acts on the door 3, the pin 14 also functions to fix the door 3 to the vehicle body 1 in addition to the hinges 2 and 2 and the lock device 5. Even if the panels 13a and 13b, the hinges 2 and 2, and the lock device 5 are not configured to have high strength as in the related art, the door 3 can be used.
Can be prevented from being bent and deformed so as to be largely displaced toward the vehicle interior 6. For this reason, the weight of the vehicle body including the door can be reduced, and the cost can be effectively reduced. When an external force is applied to the door 3, the amount of permanent deformation can be suppressed, and the weight and cost of the vehicle can be reduced, so that an ideal vehicle structure can be provided.

In the illustrated embodiment, the pin 1
4 is provided at a position far away from the hinges 2 and 2 and the lock device 5, so that when the external force F acts on the door 3, the hinges 2 and 2, the lock device 5 and the pin 14
The door 3 is fixed substantially evenly to the vehicle body 1, and the deformation of the door 3 can be suppressed more effectively.

Further, when an external force F acts on the door 3, the external force is transmitted to the vehicle body 1 via the pin 14. At this time, the hole 15 is formed in the reinforcing panel 11 of the vehicle body 1 and the center pillar constituting the skeleton of the vehicle body 1. 9 or the rocker panel 8, that is, a particularly rigid part of the vehicle body, so that the external force transmitted to the vehicle body 1
It is possible to prevent the vehicle body from being largely permanently deformed.
This can also effectively prevent the door 3 from being largely displaced toward the vehicle interior.

Further, in this embodiment, the high rigidity collar 17 is integrally fixed to the vehicle body 1, and the external force transmitted to the vehicle body 1 via the pin 14 is received by the high rigidity collar 17. Can be suppressed more reliably.

When the door 3 is closed during normal use in which no external force is applied to the automobile, the cushion member 16 attached to the pin 14 comes into contact with the vehicle body 1. In the example shown in FIG. 2, the base 16 a of the cushion member 16 contacts the outer surface of the body outer panel 10 b of the vehicle body 1 via the edge 18 a of the cap 18.

As shown in FIG. 7, a cushion member 116 made of an elastic material such as rubber is also fixed to the door of the conventional automobile. The cushion member 116 reduces the impact when the door is closed, and also allows the door 3 to be closed. Although interference with the vehicle body 1 is prevented, such a cushion member is attached to the pin 14 in the embodiment shown in FIGS. This eliminates the need for a dedicated mounting structure for mounting the cushion member to the door, and can simplify the overall configuration. Conventionally, a pin 14 is provided on a door portion provided with a cushion member 116, and a cushion member 16 is attached to the pin 14, whereby the pin 14 is also used as a member for attaching a cushion member.

Since the hole 15 formed in the vehicle body 1 is closed by a sealing cap 18, the hole 15 is inserted between the body outer panel 10b and the body inner panel 10a during normal use of the automobile. It is possible to prevent intrusion of external rainwater and dust.

The door 3 shown in FIGS. 1 to 4 may be detached from the vehicle body 1 for the purpose of repair or the like, and may be assembled again to the vehicle body 1. In this manner, the door 3 is attached to the vehicle body 1. At the time of reassembly, the pin 14 and the hole 15 can also be used as a reference for positioning the door 3, thereby improving the installation property of the door 3.

In the embodiment shown in FIGS. 2 and 3,
The cylindrical collar 17 is used, but instead of this, for example, as shown in FIG. 5, a substantially U-shape having a top wall 19a and leg walls 19b and 19c integrally connected to each end thereof is provided. A reinforcing member 19 can also be used. The reinforcing member 19 is made of a highly rigid material such as a steel plate. Such a reinforcing member 19
As shown in FIG. 6, a notch 20 formed in one leg wall 19b is aligned with a hole 15 formed in a body outer panel 10b and a reinforcing panel 11 of the vehicle body 1, and the other leg 19c is It is fixed to the inner panel 10a by, for example, a bolt 21 and a nut 22. The hole 15 is closed by, for example, a sealing cap 18 made of a synthetic resin fixed to the reinforcing member 19, and when the door 3 is closed,
The shaft 14b of the pin 14 protruding from the door 3 is shown in FIG.
In exactly the same way as in the case (1), the hole 15 is fitted. This pin 14
In addition, a cushion member 16 which comes into contact with the vehicle body 1 when the door 3 is closed is attached.
Is located at a position that does not prevent the pin 14 from being fitted into the hole 15 when the door 3 is closed.

According to the embodiment shown in FIGS. 5 and 6, in addition to the above-mentioned effects obtained by the configuration shown in FIGS. 2 to 4, the rigidity of the vehicle body 1 is further increased by the reinforcing member 19. There are also advantages that can be achieved.

The collar 17, the reinforcing member 19, the cap 18, and the cushion member 16 shown in each of the above-described embodiments are provided as necessary, and some or all of them may be omitted. When the cushion member 16 is omitted, the cushion member 11 as shown in FIG.
6 needs to be provided at an appropriate position of the door 3.

In each of the above-described embodiments, the diameter of the shaft portion 14b of the pin 14 and the diameter of the hole 15 are set so that they do not directly interfere with each other when a normal automobile is used, and the outside of the pin 3 is located outside the door 3. When the door 3 is deformed and displaced toward the vehicle interior 6 due to an external force F acting from the outside, the shaft portion 14b of the pin 14 and the hole 15 are strongly engaged with each other directly or via the cushion member 16 or the cap 18. It is set as follows. Thereby, when a normal automobile is used, generation of abnormal noise due to direct interference between the pin 14 and the hole 15 can be prevented, and when the external force F acts on the door 3, the door 3 is firmly supported on the vehicle body 1, Large permanent deformation of the door 3 is prevented.

The embodiment in which the present invention is applied to the front door 3 provided on the side of the vehicle body of the automobile has been described above. However, the present invention is not limited to this case. It can be applied to the rear door 113 or a back door (not shown) without any trouble.

[0034]

According to the first aspect of the present invention, when an external force is applied to the door from the outside by the pin and the hole fitted into the pin, the door is largely displaced toward the vehicle interior. And the rigidity of the door itself,
It is not necessary to set the strength and rigidity of the element for fixing this to the vehicle body as in the prior art, and the weight and cost of the vehicle can be reduced. Further, the mounting structure dedicated to the cushion member can be omitted, and the structure of the automobile can be simplified. In addition, the sealing cap can prevent rainwater and dust from entering the vehicle body through the hole.
