Abstract

PURPOSE:To dissolve the necessity of molding a part such as a lock reinforce ment into the special shape for fitting a bell crank so as to simplify fitting structure by fitting the bell crank, for operating the opening/closing of a back door, at the rear panel of the back door. CONSTITUTION:The finisher 33 of a license plate 6 is fixed by a leased bolt 37 at a vertical face part 29 to be a rear panel in a trunk lid 45 as a back door. In such constitution, the screw part 40 of the leased bolt 37 is inserted into the hole 32 of a recession 31 formed at the recessed part 30 of the vertical face part 29. The bush 42 of a bell crank 41 is fitted at the screw part 40, as well as a nut 44 is fastened thereto. A key rod 27 is connected to one end 43a of the crank plate 43 in the bell crank 41, and a locking plate 12 is connected to the other end 43b. A part such as a lock reinforcement 46 is not thereofore required to be molded into the special shape for fitting the bell crank 41.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bell crank mounting structure for a back door.

<Prior art> As a conventional bell crank mounting structure for a back door, there is a structure as shown in Figs. See page]. Reference numeral 1 designates a trunk lid as a back door, which is composed of an outer panel 2 and an inner panel 3 joined to the outer panel 2. trunk lid l
A recess 5 is formed in the vertical surface 4 of the outer panel 2, which serves as the "rear panel", and a finisher 7 to which a license plate 6 is attached by known means is fixed to the recess 5 by special bolts 8.

An opening 9 is formed below the inner panel 3, and a lock 10 is attached to the front side and a lock reinforcement 11 is attached to the rear side of the inner panel 3 corresponding to the lower position of the opening 9. . The lock 10 has a structure in which a locking plate 12 is rotated to rotate a lock pawl (not shown) to engage with a striker 13 provided on the vehicle body side. The lock reinforcement 11 includes a joint 14 that is joined to the inch panel 3 to reinforce the lock IO, and a rear extension 16 for anti-theft provided to prevent the locking play [2] from being manipulated from the water drain hole 15.
It consists of a mounting part 20 having a mounting hole 19 with a weld nut 18 for mounting the bell crank 17, and an inclined part 22 connecting the mounting part 20 and the joint part 14 and having an opening 21 formed in the center. and the bell crank 1
7 has a structure in which a bush 24, to which a crank plate 23 is rotatably engaged, is attached to the attachment hole 19 of the lock reinforcement 12 with a bolt 25.

One end 23a of the crank plate 23 of this bell crank 17 is connected to a key cylinder 26 disposed above.
The key rod 27 is connected to the key rod 27 which moves up and down, and the other end 23b engages with the locking plate 12 within the opening 21 of the inclined portion 22. Therefore, key cylinder 2
6 with the key, the key rod 27 rises and rotates the crank plate 23, so the other end 23b of the crank plate 23 rotates the locking plate 12.
is rotated, a lock pawl (not shown) of the lock 10 is disengaged from the striker 13, and the trunk lid 1 is opened.

<Problems to be Solved by the Invention> However, in such conventional technology, the bell crank 17 was attached using the lock reinforcement 11 for reinforcing the lock IO, so the lock reinforcement 11 had an opening 21. It was necessary to take the trouble to form the sloped part 22 of the lock reinforcement 11, the mounting part 20 with the mounting hole 19 with the weld nut 18, etc., and the shape of the lock reinforcement 11 became complicated and molding was very difficult.

The present invention has been made with attention to such conventional technology, and it is an object of the present invention to provide a bell crank mounting structure for a back door that allows the bell crank to be mounted without using lock reinforcement.

<Means and effects for solving the problem> In order to achieve the above object, the back door bell crank mounting structure according to the present invention is such that the bell crank of the back door is attached to the rear panel of the back door. .

Therefore, there is no need to mold the lock reinforcement and other parts into a special shape for bellcrank installation, making it easier to mold those parts that were conventionally used for bellcrank installation, which is also advantageous in terms of cost. becomes.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Incidentally, the same reference numerals are given to the parts common to the conventional one, and redundant explanation will be omitted.

Further recesses 31 are formed on both left and right sides of the recess 30 formed in the vertical surface portion 29 of the outer panel 28 according to this embodiment, and a hole 32 is provided at the bottom of each recess.

Further, at both left and right end portions of the finisher 33 corresponding to the recess 31, recesses 35 having the same size as the recess 31 and with the end portion 34 side open are formed. The bottom of this recess 35 is provided with an elongated notch 36 formed from the end 34 side.

Reference numeral 37 is a dedicated bolt, and the head 38 has a circumferential groove 39 formed therein for fitting into the notch 36.
A threaded portion 40 is integrally formed therein. There is one dedicated bolt 37 on each left and right in order to attach the recess 35 on both the left and right sides of the finisher 33 to the recess 30 on the outer panel 28, but the dedicated bolt 37 on the left has a longer threaded portion 40, and the one on the right Although not shown, the threaded portion of the dedicated bolt is short. Hereinafter, only the left dedicated bolt 37 with the longer threaded portion 40 will be mainly explained.

The head 38 of this special bolt 37 is attached to the finisher 33 in advance with the circumferential groove 39 portion thereof engaged in the notch 36 as described above.

Then, the threaded portion 40 of the dedicated bolt 37 attached to the finisher 33 is inserted into the hole 32 of the recess 31 formed in the recess 30 of the vertical surface portion 29. Next, the bushing 42 of the bell crank 41 is attached to the inserted threaded part 40 in an inserted state, and finally the nut 44 is tightened to the threaded part 40. Bell crank 41 installed in this way
The crank plate 43 has the key rod 27 connected to one end 43a and the locking plate 12 connected to the other end 43b, as in the conventional case.

In this way, the bell crank 41 is attached to the finisher 33 by using the dedicated bolt 37 for the trunk lit 45.
The lock reinforcement 46 in this embodiment has a simple U-shaped cross section since it is attached to the vertical surface portion 29 which is the rear panel. The upper part 47 of the lock reinforcement 46 is extended rearward to partition the drain hole 15 and the bell crank 41 to improve theft prevention. Further, in this embodiment, the vertical surface portion 29 of the outer panel 28 and the inner panel 3
As a result, the bell crank 41, the locking plate 12, and the lock IO are connected through the three parts, so that the tensile rigidity of the vertical surface portion 29 of the outer panel 28 is unexpectedly improved. Furthermore, since the bell crank 41 can be installed at the same time as the finisher 33, this is advantageous in terms of work efficiency.

<Effects of the Invention> The back door bell crank mounting structure according to the present invention has the following features:
As explained above, the bell crank of the back door is attached to the rear panel of the back door, so there is no need to mold the lock reinforcement and other parts into a special shape for attaching the bell crank. . Therefore,
These parts, which were conventionally used for attaching bell cranks, can now be easily molded, resulting in cost advantages. Additionally, the attachment of the bell crank increases the visibility of the rear panel.

Additionally, as shown in the example, if the bell crank is attached using the bolts used to attach the license plate finisher to the rear panel, the bell crank can be attached at the same time as the finisher, which improves work efficiency. It is also advantageous from the perspective of
