Description

[Detailed explanation of the invention] A. Purpose of the invention Industrial application field This invention securely attaches the inner mirror, which is suspended and supported at the front of the upper part of the passenger compartment, to the vehicle body without being affected by dimensional errors or assembly errors. This invention relates to an inner mirror mounting structure with an anti-vibration structure that can be mounted.

Conventional technology Inner mirror 1 installed in the upper front part of the vehicle interior
As shown in Fig. 3, it is composed of a mirror section 2 that reflects the rear view and a stay section 3, and the lower end of the stay section 3 is configured so that the angle of the mirror section 2 can be varied according to the difference in the viewpoint of the driver. A mirror part 2 is jointed to the mirror part 2 so that the angle thereof can be adjusted. This inner mirror 1 connects the upper end of the stay portion 3 to the vehicle body constituent member 4.
The vehicle is connected to and suspended from the vehicle so that the rear view can be seen through the rear window glass (not shown).

By the way, since the inner mirror 1 is supported on a cantilever, vibrations are transmitted to the inner mirror 1 during driving due to lack of rigidity of the stay portion 3 or lack of rigidity of the vehicle body component member 4, etc., and the mirror portion 2 swings, making it difficult to check the rear properly. Therefore, in order to increase the rigidity of the inner mirror 1, an elastic member for absorbing vibrations, such as vibration isolating rubber 6, is interposed between the stay portion 3 of the inner mirror 1 and the front window glass 5.

The anti-vibration rubber 6 is formed into a cylindrical shape, is fitted into and supported by a support protrusion 7 integrally provided on the stay portion 3 of the inner mirror 1, and has its tip abutted against the front windshield 5. The vibration of the inner mirror 1 is suppressed.

Also, as a support for the inner mirror 2,
In addition, there is a stopper 8 shown in FIGS. 4 and 5.
This forms a stay insertion hole 9 at one end of the rod-shaped body,
In addition, a through hole 10 is formed in the center of the rod-shaped body to reduce the cross-sectional area, and the stay part 2 of the inner mirror 1 is inserted into the stay insertion hole 9 and fixed, and the tip is brought into contact with the front windshield 5. I've let it happen.

Problems to be Solved by the Invention The vibration isolating rubber 6 and the stopper 8 can effectively suppress the vibration of the inner mirror 1. However, while the anti-vibration rubber 6 and the stopper 8 are formed to have a constant length, there are dimensional errors in the inner mirror 1, assembly errors between the inner mirror 1 and the vehicle body member 4, and differences between the vehicle body member 4 and the front. Due to assembly errors with the windshield 5, etc., the distance between the stay portion 3 of the inner mirror 1 and the front windshield 5 varies, making it difficult to attach the vibration isolating rubber 6 or the stopper 8. In particular, if the distance between the inner mirror 1, the front windshield 5, and the inner mirror 1 is slightly longer than the length of the anti-vibration rubber 6 or the stopper 8, reliable assembly cannot be performed, and the anti-vibration rubber 6 may easily come off. I had a problem with it falling. Therefore, it is necessary to form a large number of vibration isolating rubbers 6 and stoppers 8 with different dimensions, resulting in a lot of waste and high costs.

B. Means for solving the structural problems of the invention This invention is based on the stay part 1 of the inner mirror 17.
A support protrusion 20 is formed on the support protrusion 9, and the support protrusion 2
A spiral annular protrusion 21 is formed on the circumferential surface of the support protrusion 20, and an elastic member 22 interposed between the stay part 19 and the front windshield 16 has an inner diameter slightly smaller than the outer diameter of the support protrusion 20. The elastic member 22 is formed into a cylindrical shape, and the rear end of the elastic member 22 is fitted into the support protrusion 20, and the tip is brought into contact with the front windshield 16.

With the above structure, the inner diameter of the elastic member 22 is smaller than the support protrusion 20 formed on the stay part 19 of the inner mirror 17, and the annular protrusion 21 formed on the support protrusion 20 has a spiral shape and a wide pitch. , the elastic member 22 and the annular protrusion 21 are well attached, and the elastic member 22 is securely attached to the support protrusion 21.
is maintained. In addition, the elastic member 22 can be aligned in the front-rear direction simply by turning the elastic member 22, and since the elastic member 22 is cylindrical and has a large adjustment allowance, the stay part 19 of the inner mirror 17 and the front windshield 16 can be aligned. The vibration of the stay part 19 is reliably suppressed by absorbing the variation in dimensions between them.

Furthermore, since the elastic member 22 is cylindrical and hollow, it is easy to bend and there is little resistance to the inner mirror 17 when the inner mirror 17 is attached to the vehicle body. can also be installed between the stay part 19 and the front windshield 16,
The inner mirror 17 can be easily attached.

Embodiment FIGS. 1 and 2 are drawings showing an embodiment of the present invention. In the figures, 15 is a vehicle body member constituting a vehicle interior, and 16 is a front windshield. Reference numeral 17 denotes an inner mirror provided at the front of the vehicle interior, which is composed of a mirror section 18 that reflects the rear view and a stay section 19 that supports it.A mirror section 20 is jointed to the lower end of the stay section 19 so as to be able to adjust its angle. This inner mirror 17 has a stay part 19
The upper end is connected to the vehicle body constituent member 15 and is suspended and supported.

A support protrusion 20 is integrally formed on a part of the front surface of the stay part 19 of the inner mirror 17 facing the front windshield 16.
A spiral annular protrusion 21 is carved on the circumferential surface of the holder. The support protrusion 20 supports the inner mirror 17.
When a load above a certain level is applied to the inner mirror 17, the inner mirror 17 tilts forward, and the upper end joint of the stay part 19 comes off before the tip of the support protrusion 20 hits the windshield 16. Set the length.

Reference numeral 22 is an elastic member, such as vibration-proof rubber, provided between the front window glass 16 and the stay portion 19 of the inner mirror 17, and is formed into a cylindrical shape.
The inner diameter of this anti-vibration rubber 22 is
The stay portion 19 of No. 7 is formed to have a diameter smaller than the outer diameter of the lower support projection 20 and slightly shorter than the dimension between the stay portion 19 and the front window glass 16. This anti-vibration rubber 22 is attached to the stay part 19 by screwing the rear end side to the support protrusion 20 of the stay part 19, and the tip is brought into contact with the front windshield 16, and the middle part of the inner mirror 17 is It is supported by the front windshield 16 to increase its rigidity.

When installing the inner mirror 1 with the above mounting structure,
Anti-vibration rubber 22 is attached to the support protrusion 20 of the stay part 19 in advance.
are screwed together, and in this state, the upper end of the stay portion 19 is connected to the vehicle body constituent member 15 with a resin screw or the like, and the tip of the vibration isolating rubber 22 is brought into contact with the front windshield 16 to assemble. Note that when the stay part 19 is connected to the vehicle body constituent member 15, if the dimension between the stay part 19 and the front windshield 16 is long and a gap is created at the tip of the vibration isolating rubber 22, rotate the vibration isolating rubber 22. annular protrusion 21
It is only necessary to move the tip forward through a threaded relationship with the front windshield 16 to bring the tip end into contact with the front windshield 16.

Another attachment method is to connect the upper end of the stay portion 19 to the vehicle body component member 15, and then insert the anti-vibration rubber 22 between the front windshield 16 and the support protrusion 20. What is necessary is to screw the tip into contact with the front windshield 16.

C. Effect of the invention In this invention, a cylindrical elastic member that suppresses the vibration of the inner mirror is fitted into a support protrusion formed on the stay part of the inner mirror, and is also screwed into a spiral annular protrusion. The supporting force of the member is increased, and the elastic member does not fall off.

In addition, by rotating the elastic member relative to the support protrusion, the amount of protrusion of the elastic member can be adjusted arbitrarily, and since the adjustment margin is large, the stay part of the inner mirror and the front window glass can be adjusted as desired. Even if the dimensions between the elastic members vary due to assembly errors or the like, the tip of the elastic member can be accurately brought into contact with the front windshield.

Further, since the elastic member is simply formed into a cylindrical shape, it is easy to manufacture. Further, when assembling the inner mirror, since the elastic member is easy to bend, the elastic member may be attached to the inner mirror in advance, or the elastic member may be attached after the inner mirror is assembled. Especially in the former case, even if the elastic member hits the front windshield, by slightly bending it, the resistance to the inner mirror can be reduced and assembly can be facilitated, greatly improving assembly workability. .
