Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lock mounting structure for a vehicle opening/closing body.

Conventionally, as an example of this type of mounting structure, for example, a lock mounting structure for a back door will be explained. As shown in FIG. 2, a storage space 4 is formed at the free end portion of the door inner panel 2 so as to protrude toward the luggage room side L direction to store the lock mechanism 3;
The lock mechanism 3 was bolted and attached to this storage space via the reinforcement 5. In the figure, 6 is a rear end panel, 7 is a lock bracket fixed to the rear end panel 6, 8 is a striker fixed to the lock bracket 7, and 9 is a base plate provided with a latch that engages with the striker 8 when the door is closed. Show each.

However, in the conventional mounting structure described above, in order to form the storage space 4 for the lock mechanism 3, the door inner panel 2 must be embossed in the L direction toward the luggage room side by press molding. For this reason, not only does the thickness of the door inner panel 2 increase, but the amount of protrusion toward the luggage room side L increases by the thickness of the door inner panel 2, and the storage space on the luggage room side L is narrowed accordingly. It had the following problems.

The present invention has been devised in view of the current situation, and its purpose is to provide a panel portion narrower than the rainforest at the locking mechanism mounting portion of a vehicle opening/closing body formed by an outer panel and an inner panel. forming an opening, forming a bulge in a portion from the vertical wall of the reinforcement to the flat surface as a lock mechanism storage section for housing the lock mechanism, and causing the lock mechanism storage section to penetrate through the opening and protrude toward the inside of the vehicle body. Therefore, it is an object of the present invention to provide a lock mounting structure for a vehicle opening/closing body that can effectively expand the interior space of the vehicle by improving panel cutout and reducing the amount of protrusion of the lock mounting portion of the opening/closing body toward the interior of the vehicle. That is.

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

As shown in FIGS. 2 and 3, the opening/closing body according to this embodiment is a back door B formed of a door outer panel 1 and a door inner panel 2. A storage space 4 for the lock mechanism 3 is formed.

This storage space 4 consists of an opening 10 formed at the lock mechanism attachment part of the door inner panel 2, and a rainforth 11 formed wider than this opening 10.
The door outer panel 1 includes a lock mechanism housing section 12 formed in a portion of the rainforth 11 from the L upright wall 11a on the luggage room side to the flat surface section 11b.

That is, this lock mechanism storage portion 12 is formed by bulging a portion of the rainforest 11 from the vertical wall 11a to the flat surface portion 11b toward the luggage room side L, and the lock mechanism storage portion 12 is located in the opening 10 of the door inner panel 2. The rain force 11 is fixed to the door inner panel 2 with bolts 13 while being fitted into the door inner panel 2.

Rainforce 11 fixed in this way
A base plate 16 further provided with a latch 14 is fixed by the bolt 13, and the engagement and release operation between the latch 14 and the striker 8 fixed to the lock bracket 7 is performed by an unlatch operation linkage 15. configured for operation. Note that the lock bracket 7 is fixed to the rear end panel 6.

Therefore, in the above embodiment, the door inner panel 2
It is only necessary to drill a hole without embossing the lock attachment part of the door, which not only improves the cutting of the door inner panel 2, but also reduces the amount of protrusion toward the luggage room side L by 2 minutes from the door inner panel. , it is possible to effectively utilize the storage space on the luggage room side L.

In the above embodiment, the present invention has been explained by taking as an example a case where the present invention is applied to a vehicle having a rear door, but the present invention is not necessarily limited to this, and can also be applied to, for example, a trunk lid.

As explained above, according to this invention,
The lock attachment part of the panel constituting the opening/closing body for a vehicle can be molded without protruding into the interior of the vehicle, and the locking mechanism is installed using the storage part of the rainforest, so that the locking part of the opening/closing body can be easily molded. Since the amount of protrusion of the mounting portion into the vehicle interior can be reduced, the interior space of the vehicle can be used effectively.

Claims (1)

[Claims] 1 A vehicle opening/closing device constructed by attaching a locking mechanism to an opening/closing body formed by an outer panel and an inner panel via a reinforcement, and arranging a striker on the vehicle body side that engages with this locking mechanism when the opening/closing body is closed. In the body lock mounting structure, an opening narrower than the rainforth is formed in the locking mechanism mounting portion of the inner panel, and a portion from the vertical wall of the rainforth to the flat surface bulges out as a locking mechanism storage portion for storing the locking mechanism. 1. A lock mounting structure for a vehicle opening/closing body, characterized in that the lock mechanism storage portion penetrates the opening and projects toward the inside of the vehicle body.
