Description

TECHNICAL FIELD The present invention relates to a structure for attaching a key cylinder to an automobile door having an inner panel made of a steel plate and an outer panel made of a synthetic resin.

[Prior Art] Recently, there is an automobile door 1 shown in FIG. 16 that uses an outer panel 2 made of a synthetic resin that is lightweight and has a degree of freedom in molding. First
As shown in FIG. 18, a key cylinder 3 for locking / unlocking the door 1 is attached.

The outer panel 2 is slidably attached to the inner panel 7 in the longitudinal direction, that is, the vehicle front-rear direction by a mechanism (not shown) in consideration of thermal deformation. A fitting hole 2b having a key groove 2a is formed in the outer panel 2,
The key cylinder 3 is inserted into the hole 2b, and the key portion 3a of the key cylinder 3 is fitted into the key groove 2a to prevent rotation. Then, the clip 4 is inserted into the key cylinder 3 from the back surface side of the outer panel 2 so that the key cylinder 3 is fixed to the outer panel 2.

However, since the outer panel 2 made of synthetic resin is naturally softer than the generally used steel outer panel and the key groove 2a is easily crushed, the key cylinder 3 itself causes an arrow in FIG. 19 when an illegal input is made. Will rotate in the direction.

Therefore, there is one in which the key cylinder 3 is attached as shown in FIG. That is, one end surface portion 8a of the bracket 8 is joined to the inner panel 7 made of a steel plate, and the other end surface portion 8b of the bracket 8 is formed with a fitting hole 8d having a key groove 8c similar to the outer panel 2. . And the bracket 8
The key cylinder 3 is inserted into the fitting hole 8d of the outer panel 2 through the fitting hole 2b of the outer panel 2, and the key portion is inserted into the key groove 8c of the bracket 8.
After the 3a is fitted, the clip 4 is inserted into the key cylinder 3 from the back side of the bracket 8, and the outer panel 2 and the bracket 8 are clamped and fixed between the clip 4 and the head 3c of the key cylinder 3. Has been done. As a result, since the key cylinder 3 is fitted into the bracket 8 made of a steel plate having high rigidity, the fitting hole 8d of the bracket 8 is not crushed even when an illegal input is applied, and the key cylinder 3 rotates. Has been blocked.

[Problems to be Solved by the Invention] However, in the above-mentioned thing, the outer panel 2 made of synthetic resin is attached to the inner panel 7 made of steel plate so as to be slidable in the vehicle front-rear direction. On the other hand, since the outer panel 2 is fixed to the inner panel 7 via the bracket 8 and the key cylinder 3 at the mounting portion of the key cylinder 3, when the outer panel 2 expands and contracts due to heat, In some cases, as shown by the alternate long and two short dashes line in FIG. 20, waviness may occur at the portion where the key cylinder 3 is attached to the outer panel 2.

[Means for Solving the Problems] In order to solve the problems, the present invention provides a structure in which a key cylinder is attached to an automobile door having an inner panel made of a steel plate and an outer panel made of a synthetic resin.
The key cylinder is fixed to the bracket, and the bracket is non-rotatably supported on the inner panel or the outer panel,
In a state where the key insertion part of the key cylinder head is exposed to the outside of the vehicle from the opening of the outer panel, a seal is provided between the key cylinder head and the outer panel opening peripheral portion, and the outer panel or the inner panel, A key cylinder mounting structure for an automobile door is provided with an absorbing means for absorbing relative movement between the panel where the bracket is not supported and the key cylinder or the bracket.

[Operation] With this means, when an illegal input is applied to the key cylinder, the bracket to which the key cylinder is fixed is supported by the inner panel or the outer panel in a non-rotatable state, so that the key cylinder is prevented from rotating. The Rukoto. Further, when the outer panel made of synthetic resin is thermally deformed, the relative movement between the key cylinder and the outer panel or between the key cylinder and the inner panel is absorbed by the absorbing means, and the thermal deformation of the outer panel is absorbed and the inner panel is absorbed. Will not be transmitted to. As a result, waviness is prevented at the key cylinder attachment portion of the outer panel. Of course, even when an assembly error occurs in the key cylinder or the like, the absorbing means prevents the corrugation at the key cylinder mounting portion as in the case of the above thermal deformation.

[Examples] The present invention will be described below based on Examples.

1 and 2 are views showing a first embodiment of the present invention.

Explaining the configuration first, the door 11 of the automobile is formed of an outer panel 12 made of a synthetic resin and an inner panel 13 made of a steel plate that are lightweight and have a degree of freedom in shaping, and this outer panel 12 is an inner panel 13. In consideration of thermal deformation, it is mounted slidably in the longitudinal direction, that is, the vehicle front-rear direction. That is, from the inner panel 13, the slide portion 13a
While a bolt 13b screwed with is projected, the outer panel 12 is provided with a guide portion 12a for guiding the slide portion 13a in the vehicle front-rear direction. When the outer panel 12 is deformed by heat, the slide portion 13a slides in the guide portion 12a to allow the outer panel 12 to slide. A key cylinder 14 is attached to the door 11 as described below.

That is, first, the fixing surface portion 15a of the L-shaped bracket 15 made of a steel plate is joined to the inner panel 13, so that the bracket 15 is supported by the inner panel 13 in a non-rotatable state. This bracket 15 has this fixed surface 15a
Fitting hole with key groove 15c in the support surface part 15b bent from
15d is drilled. Further, the outer panel 12 is provided with an elongated hole-shaped opening 12b in which the key cylinder 14 is loosely inserted, along the vehicle front-rear direction. Furthermore, the outer panel
A cover 16 that closes the gap between the key cylinder 14 and the key cylinder 14 is provided. This cover 16 is a long hole 12 of the outer panel 12.
It has a substantially rectangular shape with a size that covers b, and a recess 16a that is recessed toward the vehicle interior is formed in the center. The recess 16a is sized so that the head 14a of the key cylinder 14 can be inserted therein, and a fitting hole 16c having a key groove 16b is formed. Then, the key cylinder 14 is inserted into the fitting holes 16c, 15d of the cover 16 and the bracket 15, and the key portion 14b of the key cylinder 14 is fitted into the key grooves 15c, 16b, and then from the rear surface side of the bracket 15. The clip 17 is inserted into the key cylinder 14, and the bracket 15 and the cover 16 are sandwiched between the clip 17 and the head 14a of the key cylinder 14. Further, an end rubber 18 is attached to the peripheral portion of the cover 16, and the rubber 18 comes into contact with the surface of the outer panel 12 to seal it.

As a result, the key cylinder 14 is fixed to the bracket 15, and the key insertion portion of the key cylinder head 14a is exposed to the outside of the vehicle through the opening 12b of the outer panel 12. The space between the key cylinder head 14a and the peripheral edge of the outer panel opening 12b is sealed by the cover 16 and the end rubber 18.

By the way, the opening 12b formed in the outer panel 12 has a key cylinder even if the outer panel 12 is thermally deformed and slides.
It is set to be long in the vehicle front-rear direction so as not to contact the head 14a of the vehicle. This enables relative movement between the key cylinder 14 and the outer panel 12 on which the bracket 15 is not supported, so that the outer panel 12 is not deformed.
The opening 12b constitutes the absorbing means of this embodiment.

Next, the operation of the key cylinder mounting structure having such a configuration will be described.

Since the key cylinder 14 is fitted not to the outer panel 12 made of synthetic resin but to the bracket 15 made of steel plate, the key groove 15c is crushed even if an illegal input for rotating the key cylinder 14 acts. Never with this bracket 1
Since 5 is joined to the inner panel 13, its input is carried by the inner panel 13 via the bracket 15, and the rotation of the key cylinder 14 is stopped.

On the other hand, when the outer panel 12 made of synthetic resin expands due to thermal deformation as shown by the chain double-dashed line in FIG. 1, this expansion is not transmitted to the key cylinder 14 but is absorbed by the opening 12b or the like. As a result, waviness is prevented at the portion where the key cylinder 14 is attached. Further, since the end rubber 18 slides on the surface of the outer panel 12 when the outer panel 12 is deformed, the sealing property is always ensured. Moreover, since the opening 12b of the outer panel 12 is covered with the cover 16, even if the position of the opening 12b changes as shown by the chain double-dashed line in the figure, the hole 12b is not visible from the outside of the vehicle and the appearance quality is maintained. ing.

Also, FIGS. 3 to 5 show a second embodiment of the present invention.

Compared with the first embodiment, this embodiment will first describe the cover 16
Is abolished, and the head portion 14a of the key cylinder 14 supported by the bracket 15 is located on the back surface side of the outer panel 22 made of synthetic resin. Even when the outer panel 22 is thermally deformed and the position of the opening 22b is changed as shown by the chain double-dashed line in FIG. 5, the key insertion portion 14c is always exposed from the opening 22b. The opening 22b is formed in an appropriate size. Then, the peripheral edge portion 22c of the opening 22b
An annular groove 22d is formed in the end rubber 23 that seals the groove 22d with the head 14a of the key cylinder 14.
Is installed. The absorbing means in this embodiment is that the key cylinder 14 is arranged on the back surface side of the outer panel 22, and the outer panel 22 and the key cylinder 14 are movable relative to each other.

When the outer panel 22 made of synthetic resin is thermally deformed, the panel 22 slides independently and relatively moves with respect to the key cylinder 14, so that waviness at the mounting portion of the key cylinder 14 is prevented. . Further, since the end rubber 23 is always in contact with the key cylinder 14 during this slide, the sealing property is always ensured.
At the same time, as shown in FIG. 5, even if the outer panel 22 slides and the position of the opening 22b changes, the key insertion portion 14c is always exposed, so there is no hindrance to key operation.

The rest of the configuration and operation are the same as in the first embodiment, so a description thereof will be omitted.

Next, FIGS. 6 and 7 show a third embodiment of the present invention.

In this embodiment, the opening 22b of the outer panel 22 of the second embodiment is used.
An annular member 25 is attached to the peripheral edge portion 22c of the same by adhesion or the like, and an end rubber 23 that seals the gap with the head portion 14a of the key cylinder 14 is attached to this member 25.

Even in this case, the same effect as that of the second embodiment can be obtained. Of course, the other structure is similar to that of the second embodiment.

Further, FIGS. 8 and 9 show a fourth embodiment of the present invention.

In the key cylinder 34 of this embodiment, the head 34a has the bracket 1
It is formed to be larger than the fitting hole 15d of 5 and the head 34
An oval flange 34b larger than the opening 12b of the outer panel 12 is formed in a. Then, the key cylinder 34 is fitted into the fitting hole 15d of the bracket 15, the clip 17 is inserted from the rear surface side of the bracket 15, and the bracket 15 is sandwiched between the clip 17 and the head 34a of the key cylinder 34. By doing so, the key cylinder 34 is attached. In this state, the key cylinder 34 is loosely inserted in the opening 12b of the outer panel 12, and the outer panel 12 and the key cylinder 34 can move relative to each other. At the same time, the seal rubber 35 attached to the peripheral portion of the flange portion 34b of the key cylinder 34 is in contact with the peripheral portion of the opening 12b of the outer panel 12. The absorbing means of this embodiment is also constituted by the opening 12b of the outer panel 12.

Also in this case, the non-rotatability is secured by the bracket 15 as in the above-described embodiments, and even when the outer panel 12 made of synthetic resin is thermally deformed, the panel 12 and the key cylinder 34 are relatively opposed to each other. Since it is movable,
The deformation is absorbed and the outer panel 12 is prevented from waving. Further, since the seal rubber 35 is always in contact with the outer panel 12, the sealing performance is always ensured, and the opening 12b of the outer panel 12 has the flange portion 34b of the key cylinder 34.
Since it is always covered with, the opening 12b is not visible from the outside of the vehicle and the appearance quality is maintained in a good state.

Instead of enlarging the head 34a of the key cylinder 34 as described above, a collar 36 may be attached as shown in FIG.

Furthermore, FIGS. 11 and 12 show a fifth embodiment of the present invention.

In this embodiment, unlike the above embodiments, the bracket 45 is not fixed to the inner panel 13,
On the other hand, a fitting hole 45b having a key groove 45a is formed,
A notch portion 45c extending in the vehicle front-rear direction is formed on one end side. Further, the outer panel 42 is not formed with the opening 12b as in the above embodiment, but is formed with an opening 42a in which the key cylinder 14 is fitted almost exactly.

The key cylinder 14 is inserted into the fitting hole 45b of the bracket 45 and the opening 42a of the outer panel 42, and then the clip 17 is inserted, and the clip 17 and the head of the key cylinder 14 are inserted.
The outer panel 42 and the bracket 45 are sandwiched between the outer panel 42 and the bracket 14a. And the notch 45c of this bracket 45
A bolt 13b protruding from the inner panel 13 is inserted in the. As a result, the bracket 45 is supported by the outer panel 42 in a non-rotatable state by the bolt 13b.

Now, when an illegal input is applied to the key cylinder 14, the bracket 45 tries to rotate in the direction of the arrow in FIG. 12, but this rotation is caused by the bolt 13 protruding from the inner panel 13.
As a result of being blocked at b, the key cylinder 14 is prevented from rotating, and the door lock device 6 is not released via the rod 5 and the anti-theft property is secured.

Further, the absorbing means is different from the above-mentioned embodiments in that the bracket
45 and the inner panel 13 are not fixed. According to this, the bracket 45 and the inner panel 13 can be moved relative to each other, and when the outer panel 42 is thermally deformed, the key cylinder 14 and the bracket 45 are also slid together with the slide of the outer panel 42, and the inside of the notch portion 45c of the bracket 45 is moved. The bolt 13b moves. Therefore,
The deformation of the outer panel 42 is absorbed without being transmitted to the inner panel 13, and the waviness does not occur at the key cylinder 14 mounting portion of the outer panel 42.

According to this embodiment, it is not necessary to form the opening 42a of the outer panel 42 in the shape of an elongated hole, and the key cylinder 14 is fitted exactly on the outer panel 42, so that the key cylinder head
It can be said that the space between 14a and the peripheral portion of the outer panel opening 42a is sealed and the appearance is further improved.

Furthermore, FIGS. 13 to 15 show a sixth embodiment of the present invention.

The bracket 55 of this embodiment is not fixed to the inner panel 13 as in the above embodiment, and the bracket 55 has
A fitting hole 55b having a key groove 55a is formed.
After the key cylinder 14 is fitted into the opening 42a of the outer panel 42 and the outer panel 42, the clip 17 is inserted and
Bracket 55 between 17 and the head 14a of the key cylinder 14.
And the outer panel 42 is sandwiched, and the key cylinder 14 is attached. The bracket 55 is connected via a rod 56 to a fixed plate 57 fixedly mounted on the inner panel 13. Both ends 56a of the rod 56 are rotatably connected to the bracket 55 and the fixing plate 57 in a loosely fitted state.

As a result, the bracket 55 is in a non-rotatable state by the rod 56, the fixing plate 57, and the like, and when an illegal input is applied to the key cylinder 14, the bracket 55 tries to rotate. The rotation of the key cylinder 14 is prevented by being prevented by being loaded by the fixing plate 57 fixedly attached to the inner panel 13 via the.

Further, the absorbing means is a fixed plate fixed to the inner panel 13.
A bracket 55 is rotatably connected to a bracket 57 by a rod 56 in a freely fitted state. That is, when the outer panel 42 is thermally deformed, the bracket 55 also moves integrally as the outer panel 42 slides, as shown by the chain double-dashed line in FIG. Substantially, the bracket 55 tries to move in an arc shape around the fixing plate 57 via the rod 56, but in this case, since both ends 56a of the rod 56 are connected in a loosely fitted state, this bracket The relative movement between the bracket 55 and the inner panel 13 is absorbed without affecting the movement of the 55 in the substantially horizontal direction.
As a result, the deformation of the outer panel 42 is absorbed without being transmitted to the inner panel 13, and the waviness at the mounting portion of the key cylinder 14 is prevented.

In each of the above embodiments, the case where the key cylinder 14 and the outer panel 12 or the inner panel 13 move relative to each other due to the thermal deformation of the outer panel 12, has been described.
The present invention is not limited to this, and even when the key cylinder 14 is relatively moved due to an assembly error, the waviness is similarly prevented at the mounting portion of the key cylinder 14.

[Effects of the Invention] As described above, according to the present invention, the rotation of the key cylinder is prevented when an illegal input is applied to the key cylinder. Even when the outer panel made of synthetic resin is thermally deformed or an assembly error occurs in each panel or the like, and the relative movement occurs between the key cylinder and one of the outer panel and the inner panel, the outer panel is absorbed by the absorbing means. Deformation and the like are not transmitted to the inner panel, and a waviness at the key cylinder mounting portion can be prevented, which is a practically useful effect.
