Description

[Detailed description of the invention] The present invention relates to a vehicle rearview mirror in which the reflection angle of the mirror can be adjusted by remote control.
In particular, the present invention relates to a structure for pulling out a mirror remote control cord or wire that passes through a movable mounting base of a mirror stay.

Conventionally, in wire set or electric rearview mirrors that remotely control the reflection angle of the mirror, when an impact force is applied to the mirror body, the mirror stay body rotates around the base where it is attached to the vehicle body. The structure is such that the mirror body can be tilted or rotated to reduce the impact force, thereby preventing damage to the mirror body and damage caused by the force of an opponent that comes into contact with the mirror body. A signal cord or wire extended from a remote location such as the main body is introduced through the mounting base of the main body of the stay.

However, in the past, the cord twisting or wire introduction position (drawing out position) was far away from the center of rotation of the stay body, so the stay body could be dislodged from the mounting base due to impact force, and the stay body could easily move around the support bolt. If the stay body is rotated 90 degrees or more, the wire or cord may be pinched or pulled between the stay body and the base, damaging the wire or cord. In addition, there were other drawbacks, such as limiting the impact-reducing action of Mira's body.

The present invention was devised in view of the above points, and it is designed to bring the lead-out point of the signal cord or wire connected to the reflection angle adjustment drive mechanism of the mirror as close as possible to the center of rotation of the main body of the stay, and By holding the cord or wire pull-out part on the mounting base of the stay body, damage to the cord or wire due to rotation of the stay body can be prevented.
In addition, it is an object of the present invention to provide a rearview mirror for a vehicle in which the shock-reducing operation of the stay main body is facilitated.

An embodiment of the present invention will be described below based on the drawings.

Referring to FIG. 1, reference numeral I designates a stay main body that has a mirror accommodating portion 1a at the top and an elliptical installation leg 1b at the lower end. An electromagnetic drive device 3 for adjustment is integrally installed with a frame 4 button and a screw 5, and the mirror 2 is vertically arranged in the front opening Ic of the housing portion 1a so as to close it. The rear part thereof is integrally fixed to the movable part 3a of the drive device 3, and a signal cord 6 for supplying a reflection angle adjustment signal of the mirror is connected to the drive device 3. is drawn out to the lower surface side of the installation leg 1b.

Further, a connecting tool 7 is fixed to the inside center of the installation leg 1b in the stay main body I with a screw 8, and the upper end of a support bolt 9 is located at the center of the lower surface of this connecting tool 7, that is, approximately at the center of the installation leg 1b. They are connected via a universal joint 10, and a spring receiver 12 is attached to the hanging end.

3 is a rearview mirror mounting portion of a vehicle body corresponding to the fender of an automobile, etc., and a retainer I5 for reinforcement is disposed on the outer surface and back surface of the vehicle body I3, respectively, facing each other between the lower surface of the mounting base and for reinforcement. The mounting base 14 has an elliptical shape similar to the installation leg [b] of the main body opening of the stay body, and an endless groove 14b is formed on the periphery of its upper surface to which the installation leg [b] removably engages. and mounting base 1
As shown in FIGS. 1 and 2, a cylindrical body 14b into which the support bolt 9 is inserted is protruded from approximately the center of the inner lower surface of the cylindrical body 14b, and its tip is connected to the vehicle body. 3 through the center hole f5aK of the retainer I5.

Then, a compression spring 16 is inserted between the lower surface of the retainer I5 and the spring receiver 12 held by the bolt 9, and the spring force of the compression spring 16 generates a tensile force on the bolt 9 to install the stay main body I. The legs]b are pressed into the grooves f4b of the mounting base I4 to stably hold the stay main body I between the lower surfaces of the mounting bases.

7. This is the draw-out hole for the cord 6 formed in the fixed base I4, and the draw-out hole I7 is as close as possible to the support bolt 9 of the stay main body I as shown in FIGS. 1 and 2. is formed on the side of the cylindrical body f4b, and the distance between the axis of the support bolt 9 and the cord 6 is reduced by means of the hinge main body]
To reduce the movement of the cord 6 when the cord 6 is rotated around the support bolt 9, and to prevent it from being exposed outside the outer frame of the installation leg]b.

Further, on the lower surface of the mounting base τ4 that is spaced outward from the cord pull-out hole I7, there is a cord holding piece 18 extending in a direction perpendicular to the downward direction of the base, and outside of this holding piece 18, 11:
Cord holding piece that protrudes perpendicularly from the bottom surface of the base]
9 are formed respectively, and the cord 6 pulled out from the pull-out hole 17 is bent into an L shape and inserted between the presser piece 18 and the lower surface of the base, and then the cord 6 is attached to the base using the presser piece I8 as a base point. Bend it at right angles to the lower blade and attach the presser piece 18.1.
9, thereby securely holding the cord 6 on the base I4 and preventing the cord 6 from sliding excessively even if a tensile force is applied to the cord 6.

Further, the other end of the cord 6 extending from the holding piece 18°I9 passes through the vehicle body 13 and is connected to a signal transmitter in the driver's seat.

20 is a cover that protects the spring receiver 2 and the compression spring Ib.

In the rearview mirror configured as described above, when the mirror body, that is, the seat housing portion 1a of the stay body 1 comes into contact with a person or other object and receives an impact force, the installation leg of the stay body 1b comes off from the groove f4a of the mounting base 14 against the holding force of the compression spring Ib, and is rotated about the support bolt 9 as shown in FIG. 3 so as to alleviate the impact force.

At this time, since the cord 6 is close to the center of rotation of the stay main body I, it is not exposed outside the outer frame of the installation leg b, and therefore the cord 6 is sandwiched between the installation leg 1b and the mounting base. There is no such thing.

It goes without saying that the present invention is not limited to electric rearview mirrors as shown in the embodiments, but can be similarly applied to rearview mirrors with a set of wires.

As described above, in the present invention, the lead-out point of the signal cord or wire connected to the mirror angle adjustment drive mechanism is brought as close as possible to the rotation center of the stay body, and the cord or wire is Since the drawer part is held on the mounting base of the stay body, even if the stay body rotates due to external impact force, the cord or wire will not be exposed from the leg outline of the stay body, or the leg There is no risk of the cord or wire being pinched between the bracket and the mounting base, and the movement of the cord or wire due to the rotation of the stay body is small, so there is no need to apply excessive force to the cord or wire, and the cord or wire can be easily twisted. In addition to being able to prevent damage, there are advantages in that the shock mitigation operation of the stay body becomes easier and more reliable.

In addition, the cord or wire pull-out part is held in a bent state by a presser piece provided on the underside of the mounting base, so even if bow tension is applied to the cord, the cord will not slide excessively. can be prevented.
