Description

[Detailed description of the invention] The present invention allows the outer mirror support stay to tilt elastically with respect to the car body when a strong external force is applied, so that the mirror or the mirror support structure is not easily damaged. Regarding the mounting structure of the mirror.

Various mirror mounting structures have been provided in the past as this type of mirror mounting structure, but all of them have a structure that requires work from both the outside and inside of the body when mounting. There were problems such as the narrow space inside the machine and the necessity of working in an upward position, resulting in poor work efficiency.

The present invention has been made in view of the above-mentioned conventional circumstances, and provides a new outer mirror mounting structure that is easy to assemble and allows all operations to be performed from outside the body.

The present invention will be specifically described below with reference to the illustrated embodiments.

First, the first embodiment shown in FIGS. 1 and 2 will be described.

1 is a stay for supporting an outer mirror (not shown); 5 is a seat plate that supports the bottom surface of the stay; 4 is the seat plate 5
is the body to which it is fixed.

A generally cylindrical bottomed casing 6 containing a coil spring 7 and a stopper 8 is fixed to the lower surface of the stay 1 before the stay is attached to the body 4.

The casing 6 has l pairs of mounting wings 6a on its upper portion and a pair of cutout windows 6b on its side.

Each of the mounting wings 6a has a screw insertion hole 6d, and a wire harness insertion hole 6c at the lower bottom.

The stopper 8 is cap-shaped and has a wire harness insertion hole 8c at its upper bottom and a pair of legs 8a below it.

The lower end of each leg 8a is provided with an engaging protrusion 8b extending radially outward.

First, the coil spring 7 is inserted into the cylinder of the casing 6, and then the stopper 8 is moved so that each engagement protrusion 8b projects outwardly through the cutout window 6b. It is placed over the top of the .

Next, the stay seat plate 5 having a casing insertion hole 5d in the center is fitted onto the outer periphery of the casing from below.

The seat plate 5 has a projecting peripheral wall 5 on the outer periphery of its upper surface, into which the lower surface of the stay fits, and a pair of screw insertion holes 5b on both sides of the central casing insertion hole 5d.

The casing insertion hole 5d is approximately circular, but the seat plate 5
A pair of notches 5c at opposite positions along the longitudinal direction of
Also, a pair of grooves 5a are provided on the lower surface around the insertion hole at positions perpendicular to the pair of notches 5C.

Thus, when the seat plate 5 is externally fitted onto the casing 6, the pair of engagement protrusions 8b of the stopper 8 pass through the notches 5c of the insertion hole 5d of the seat plate 5.

When each engagement protrusion 8b of the stopper 8 is located below the seat plate 5, the seat plate 5 is slightly rotated relative to the casing 6 and the stopper 8, and the engagement protrusions 8a
b is locked to the lower surface of the seat plate 5.

Next, in the above state, the wire harness 3 guided through the guide hole 2 by an electric mirror angle adjustment device (not shown) is inserted into the center of the coil spring and the casing 6 through the insertion hole 8c of the stopper 8. It is guided downward through the hole 6c, and then the pair of attachment wings 6a of the casing 6 are fixed to the lower surface of the stay 1 with screws 9.

In this state, the lower surface of the stay 1 is deviated from the normal position with respect to the seat plate 5, and the pair of screw insertion holes 5b of the seat plate 5 are exposed outside the lower surface of the stay 1.

Therefore, next, the seat plate 5 is applied to the outer surface of the mounting hole 4a of the body 4, the casing 6 is inserted into the mounting hole 4a of the body 4, and the seat plate 5 is attached to the screw 10.
Therefore, it is fixed to the body 4.

Next, the stay 1 is rotated with respect to the seat plate 5 together with the casing 6, etc., and the lower surface of the stay 1 is aligned with the projecting peripheral wall 5e of the seat plate 5.
to hide the screw 10.

The assembly is completed by the above operations, and the upper and lower ends of the coil spring 7 are supported in a compressed state by the stopper 8 and the bottom of the casing 6, and the stay is pressed against the seat plate 5 by the spring force of the coil spring 7. .

When an external force is applied to the stay 1, the stay tilts and floats with respect to the seat plate 5 using a part of the outer periphery of the stay as a fulcrum depending on the direction and magnitude of the external force.
When the external force is released, the stay 1 is returned to its original position by the spring force of the coil spring 7.

Next, a second embodiment shown in FIGS. 3 and 4 will be described.

Incidentally, the same members as those in the first embodiment are given the same reference numerals, and detailed explanations will be omitted.

In this embodiment, a stopper 8' corresponding to the stopper 8 of the first embodiment is in the shape of a disk with a central portion protruding slightly upward, and is arranged in l pairs approximately Y to form a ring-shaped portion 8d in the central portion. A letter-shaped notch 8e is provided.

A hole 8'c in the center of the stopper 8' is a wire harness insertion hole.

When fitting this stopper 8' onto the casing 6 in which the coil spring 7 is housed from above, the casing 6
A pair of mounting wings 6a and a cylindrical portion enter into a pair of notches 8e of the stopper 8', and conversely, a pair of connecting portions 8f supporting a ring-shaped portion 8d of the stopper 8' fit into a notch of the casing 6. Enter window 6b.

In addition, the seat plate 5' in this embodiment has one part in its longitudinal direction.
A groove 5f is formed on the side surface into which a part of the periphery of the mounting hole 4a of the body 4 fits, and a groove 5f is formed on the side opposite to the above.
Two screw insertion holes 5b are formed.

Furthermore, a pair of notches 5'c of the casing insertion hole 5d
are provided in a direction perpendicular to the longitudinal direction of the seat plate 5, respectively.

This seat plate 5' is externally fitted onto the casing 6, into which the stopper 8' is externally fitted, from above.

In this case, the l pair of mounting wings 6a of the casing 6 are each attached to a seat plate 5.
' passes through a pair of notches 5'c of the insertion hole 5d.

In the above state, the pair of mounting wings 6a of the casing 6 are brought into contact with the lower surface of the stay 1 and fixed with screws 9.

The screw 9 can be screwed in through each notch 5'c of the insertion hole 5d of the seat plate 5'.

In this state, the longitudinal force direction of the stay and the longitudinal direction of the seat plate 5' are perpendicular to each other, and the screw insertion hole 5b of the seat plate 5' is exposed from the lower surface of the stay 1.

Therefore, when the seat plate 5' is then fixed to the body 4 with the screws 10, it can be easily done without the stay 1 interfering.

After fixing the seat plate 5' to the body 4, turn the stay 1 to 90°.
Rotate to position the lower surface of the stay 1 at the correct position on the seat plate 5'.

As is clear from the detailed description of the two embodiments above,
According to the present invention, the stay, casing, stopper, and coil spring can be assembled separately from the body, and this assembly can also be assembled into the mounting hole from the outside of the body with a simple operation. This makes the entire assembly process very easy and efficient.

In addition, fewer parts are required overall, and since the coil spring is housed in the casing, the wire harness can be guided downward through the casing, so the hole for inserting the wire harness can be placed in the seat. There is no need to specially open the board, making wiring much easier.
