Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a key cylinder mounting structure for a trunk lid of an automobile.

Conventionally, a retainer is used to attach a key cylinder to a trunk lid, as shown in, for example, Japanese Utility Model Application No. 52-112024. In detail, as shown in FIG.
Neck 13 of key cylinder 12 attached to 1
A locking piece 14 is provided in the insertion hole 17, and a retainer 15 is provided in the lower surface of the lid reinforcement 16.
the locking piece 14 and the lid panel 1.
1, and the outer end of the retainer 15 was fixed to the lid reinforcement 16 with a screw body 18 so that the retainer 15 would not fall off.

However, in this structure, the seal rubber 21 inserted between the lid 19 and the opening 20 covered by the lid 19 is
Because the retainer 15 is located in the vehicle body 23, rainwater and washing water from the outside enters the retainer 15 and its insertion hole 17.
If it comes into contact with and gets damaged by vibration, it will easily rust. Furthermore, the gap 2 between the lid 19 and the opening 20 is
4 from the outside, it will easily reach the retainer 15 and the screw body 18, so the retainer 15
Pull out the key cylinder 12 and attach it to the lid panel 1.
Removing it from 1 immediately invites theft.

Furthermore, there is also a conventional mounting structure as shown in FIG. In the same figure, the seal rubber 21
An aperture 26 is formed in the lid reinforcement 16 at an inward position 25, and an operator can insert his or her hand through this aperture 26 to remove the retainer 1.
5 is locked between the locking piece 14 of the key cylinder 12 and the lid panel 11. Although this structure prevents the infiltration of rainwater and theft, the height H of the lid reinforcement 16 is generally subject to design constraints, and the above-mentioned opening 26
Since the retainer 15 cannot be made sufficiently large, there is a drawback that the work of locking the retainer 15 is not easy.

Furthermore, since the rotation range of the key cylinder 12 is generally narrow, if there is a shift in the position of the key cylinder 12, the locking and unlocking operations become unstable. In both cases, since the tip 27 of the key cylinder 12 is not supported by the lid 19, there is a drawback that the tip 27 swings when the key is operated, resulting in unstable operation.

This invention has been made to solve the above-mentioned conventional drawbacks, and includes a support part that supports the tip of the key cylinder, and a retainer that is attached to the tip of the key cylinder inward from the seal between the lid and the opening. To provide a lid key cylinder mounting structure that stabilizes the operation of a key cylinder by engaging with a formed engagement groove, effectively prevents rusting and theft, and has excellent assembly workability. The purpose is to

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 3, a lid reinforcement 16 is attached to the inner surface of a lid panel 11 constituting the outer surface of the lid 19, and a space 31 is formed between the lid reinforcement 16 and the lid panel 11. A lock case 32 is fastened to the lid reinforcement 16 by a screw body 55, and a lock member 33 is attached to the lock case 32.
As shown in FIG.
The lid 19 is held locked to the vehicle body 23 by receiving rotational force in six directions and engaging the striker 38 fixed to the vehicle body 23 in FIG. On the other hand, the key cylinder has an outer case 12a and a rotation shaft 12b inside the outer case 12a that is rotated by a key 41. A rotation piece 39 is fixed to the tip of the rotation shaft 12b, and a rotation piece 39 is fixed to the tip of the rotation shaft 12b. The member 27 is pivotally supported.
Note that the movement of the tip member 27 in the left-right direction in the drawing is restricted by a pin or the like. The lock member 33
has a protrusion 33a at the upper end, and this protrusion 3
A rotating piece 39 attached to the rotating shaft 12b of the key cylinder 12 is in contact with the key cylinder 3a, and the rotation of the rotating piece 39 allows the locking member 33 to be locked or unlocked. When the key 41 is inserted into the key cylinder 12 and turned in the unlocking direction, the rotating piece 39 rotates the lock member 33 in the direction of arrow 42 in FIG. 4, releases the lock from the striker 38, and locks. Release the condition.

A support portion 43 for supporting the tip member 27 of the key cylinder 12 is formed in a protruding manner in a portion of the lid reinforcement 16 in FIG. 3 located outward 22 from the lock member 33. , is inserted from the outside into a fitting hole 44 provided in the lid panel 11 that engages with a protrusion 12c formed on the outer case 12a of the key cylinder 12, and its tip member 27 is inserted into an insertion hole 45 provided in the support portion 43. inserted into. Reference numeral 46 denotes a retainer for supporting the tip member 27, which has a bifurcated shape with a curved portion 40a as shown in FIG.
The tip member 2 is inserted into the lid reinforcement 16 located at
As a result, the key cylinder 12 is firmly held with the tip member 27 supported by the support portion 43 by the elastic force of the curved portion 46a of the retainer 46.

FIG. 6 shows another embodiment of this invention,
A lock reinforcement 49 is welded to the lid reinforcement 16, and a support portion 43 is provided on the lock reinforcement 49.

An insertion hole 51 is provided on the lower surface of the lid reinforcement 16, located inwardly 25 from the seal rubber 21 in FIG.
The retainer 46 is inserted from the key cylinder 12
It is engaged with the engagement groove 47 provided in the tip member 27 of. This kind of rock reinforcement 49
When provided, a closed cross section is formed by the lid reinforcement and the lock reinforcement, so that the supporting portion 43 of the tip member 27 and the portion of the lock case 32 that connects to the lid reinforcement 16 are reinforced. .

This invention is constructed as described above, and since the tip of the key cylinder is firmly supported, vibration of the tip is eliminated and the operation of the key cylinder is stabilized. Further, since the retainer that holds the key cylinder is located inward from the seal portion, rusting caused by rainwater and the like and theft are effectively prevented. Furthermore, the retainer is designed to be inserted from the bottom side of the lid reinforcement, which is easy to insert, and is engaged with the engagement groove at the tip of the key cylinder so that it does not fall off easily. Since screwing as in the conventional example is not required, the retainer engagement work, that is, the key cylinder installation work is facilitated.
