Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for an automobile mirror, and particularly to a mounting structure for a mirror disposed on the outer surface of a vehicle body, such as a door mirror.

The fenders and door mirrors of automobiles are equipped with fender mirrors and door mirrors to ensure sufficient rearward visibility for the driver. It is installed so that it can be tipped over to prevent injury to the human body. A conventional example of such a mirror mounted so that it can be tipped over is shown in FIG. 1, for example. This shows a door mirror attached to the outer surface of a vehicle door 12, and this door mirror is made by attaching a base 13 to the door 12 with fasteners such as screws, and attaching the mirror body 2 to the surface of the base 13. A spring 4 is interposed between the mirror body 2 and the base 13, and the mirror body 2 is fixed to the base 13 by the elastic action of the spring 4. There are bosses 5 in several places inside the mirror body 2,
A reinforcing member 3 made of a rigid metal material is attached to these bosses 5 and 6 with screws 7 and 8, and increases the rigidity of the mirror body 2 and supports the action of the spring 4. It's on. A mirror pivot 9 protrudes from the reinforcing member 3, and the mirror 1 is connected to the mirror pivot 9 via a pivot holder 10. Therefore, the mirror 1 can rotate within the mirror body 2 about the mirror pivot 9. The spring 4 consists of a tension spring wound into a coil, and the tip end 4a is connected to the mirror body 2 via the reinforcing member 3 or the boss 5, while the base end 4b penetrates the bottom wall 2a of the mirror body 2 and connects to the base 13. engaged. In this way, the spring 4 exerts a compressive force on the mirror body 2 in the direction of the arrow S in FIG. 1, keeping the mirror body 2 upright with respect to the base 13. When it collides, it resists the force of the spring 4 and falls over, taking the position shown by the two-dot chain line in FIG. Reference numeral 11 in the figure is an actuating member that engages with an operating lever (not shown) having an operating portion protruding into the vehicle interior to remotely control the mirror 1.

However, in such a conventional mirror mounting structure, the mirror body 2 is held in pressure contact with the base 13, that is, the vehicle body side member by the spring force of the spring 4. In the case where the mirror body 2 falls due to a collision, the larger the amount of falling displacement of the mirror body 2, the more the spring 4 is pulled, and the greater the restoring force used for the mirror body 2.
That is, when a human body collides with the mirror body 2, the load that the human body receives is approximately equal to the pressure holding force to keep the mirror body 2 upright, but as the mirror body 2 falls down, the load is applied to the human body. The load increases proportionally. Therefore, it is necessary to set the elastic constant of the spring 4 as low as possible to reduce the pressure holding force. However, if this pressure holding force is set small, the mirror body 2 and the mirror 1 will vibrate when the vehicle is running, resulting in poor rear visibility. There was a risk that a problem would occur where the
(See Publication No. 56-8543).

The present invention was devised by focusing on such conventional problems, and its purpose is to provide a mirror that is attached to the outer surface of a vehicle body by means of a holding member, in which the holding member has a fixed part at one end and a fixed part at the other end. A stopper is integrally formed in the middle part, and a wide part that can be elastically deformed is integrally formed in the middle part to make it flexible and deformable.One fixed part of the vehicle body side mounting part and the mirror body is fixed, and an opening is formed in the other. By providing a mirror mounting structure in which the wide portion is engaged with the opening, the mirror body is held upright against the outer surface of the vehicle under normal conditions by the engagement action between the wide portion and the opening.
When a human body or the like collides with the mirror body, as the mirror body falls, the wide part elastically contracts and bites into the opening, and finally passes through the opening and releases the engagement between the two, causing the mirror body to collapse. The object of the present invention is to separate the mirror body from the outer surface of the vehicle body and further support the mirror body with a stopper to prevent it from falling off, thereby solving the above-mentioned conventional problems.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 to 5 are diagrams showing an embodiment of the present invention. The mirror mounting structure according to this example is as follows:
Attach and fix the base 13 to the outer surface of the vehicle body such as a door,
A mirror body 2 is mounted on the upper surface of this base 13 at 13a.
At the same time, a holding member 19 is interposed between the mirror body 2 and the base 13, and the holding member 19 holds the mirror body 2 in pressure contact with a mounting part on the vehicle body side such as the base 13. ing.

The holding member 19 is made of a flexible member in which band-shaped metal plates in which a slit 27 is formed are folded in the center and overlapped with each other, and has a fixing part 19b having a screw hole 23 at one end, and a fixing part 19b having a screw hole 23 at the other end. The stopper part 19a is formed by forming a folded part of a metal plate into a loop shape so as to protrude in a direction perpendicular to the surface, and the fixing part 1
At a position near the fixing part 19b in the intermediate part between the stopper part 9b and the stopper part 19a, there is an elastically deformable wide part 19c formed by bending and bulging out the metal plate parts overlapped with each other. has
A plurality of fixing portions 19b are fixed to a mounting flange 21 provided on the base 13 with screws 22 at two locations in the vertical direction. On the other hand, an opening 28 is formed in the bottom surface 2a of the mirror body 2, and a mount 24 for reinforcing this opening is attached with screws 25. The mount 24 has a wide portion 19 so as to be able to engage with the wide portion 19c of the holding member 19.
An opening 20 having a diameter smaller than c is formed. To attach the mirror body 2, insert the stopper part 19a at the tip of the holding member 19 attached to the base 13 into the opening 20 with a certain angular relationship, and then apply the opening 20 to the wide part 19c. When the mirror body 2 is pressed toward the base 13, the wide portion 19c receives compressive force and elastically contracts, and the opening 28 of the mirror body 2 closes to the wide portion 19c.
c is moved from the stopper part 19a side to the fixed part 19b side, and the mirror body 2 is held in pressure contact with the base 13 by the restoring force of the wide part 19c. In order to ensure this pressure contact and holding, an inclined surface 30 is provided at the opening edge of the mount 24.

A boss 5 is provided inside the mirror body 2, and a bracket 14 is attached to the boss 5 with screws 7. The mirror 1 is connected and supported by the bracket 14 via a pivot receiver 15. The mirror 1 is held by a mirror cover 17, and the mirror cover 17 is located approximately in the center of the mirror cover 17.
A pivot portion 17a is provided integrally with the pivot portion 17a.
The pivot portion 17a is rotatably attached to the pivot receiver 15 by a screw member 16 screwed into the bracket 14 and a spring 18 engaged therewith, thereby supporting the mirror cover 17 and the mirror 1 so as to be adjustable in angle.

In an automobile mirror having such a configuration,
A case where a human body collides with the mirror body 2 will be explained. The mirror body 2 receives an external force in the direction indicated by the arrow in FIG. 5, and begins to rotate about the fulcrum 29. Due to this rotational movement, the mount 24 attached to the mirror body 2 moves relative to the holding member 19 toward the distal end, and as shown in FIG. 4, the opening 20 is displaced while engaging with the wide portion 19c. do. As a result, the wide portion 19c is compressed and moves relative to the opening 20 in the direction of exiting as the mirror body 2 rotates, and when the mirror body 2 rotates by a predetermined angle, the wide portion 19c is completely compressed.
deviate from This operation of detaching from the wide portion 19c is completed with a slight rotation angle of the mirror body 2, so it is accomplished in an extremely short time. The mirror body 2 that has come off the wide part 19c is moved by the holding member 1 which is bent and deformed by the weight of the mirror body 2.
9, slides from position A to position B, as shown by the two-dot chain line in Fig. 5, and reaches position C, where the stopper part 1
9a is suspended by engaging with the opening 20 of the mount 24. As described above, the holding member 19 is made of a strip-shaped thin plate and has the slit 27 formed therein, so that it has sufficient flexibility so that when the mirror body 2 is sliding, a human body or the like will not come near the mirror mounting part of the vehicle body. It bends so that almost no impact load is applied until it completely passes through. For this reason, the human body, etc., receives a shock only for a moment when it collides with Miraboday 2, and does not receive any force after that, so that the shock at the time of the collision can be minimized.

In this embodiment, the fixed part 19b is fixed to the base 13, and the distal end portion provided with the stopper part 19a is inserted into the mirror body 2. However, in contrast to this, the fixed part 19b is fixed to the base 13. It may be fixed to the second side and the tip portion inserted into the base 13 or inserted into the vehicle body panel. Also,
Although the mirror body 2 is designed to be attached to the outer surface of the vehicle body via the base 13, the attachment is not necessarily limited to this type of attachment. It's okay. Regarding the holding part 19, in the above embodiment, a rectangular space is formed in the wide part 19c, but this space is filled with an elastic material such as rubber to hold the wide part 19c in pressure contact. It is also possible to adjust the force, and instead of providing the slit 27 in the holding member 19, the strip-shaped plate material can be made thinner or thinner, or the stopper part 19 can be made thinner or thinner.
The deflection performance of the holding member 19 may be adjusted by using a single sheet of material only between the wide portion a and the wide portion 19c.

As explained above, according to the present invention, the fixing part, the stopper part, and the wide part are formed in the holding member, and the mirror body and the vehicle body side mounting part are held in pressure contact with each other by the engagement action of the wide part. When an impact force is applied to the mirror body, the engagement of the wide portion is instantly released and the mirror body is detached from the vehicle body attachment part, so that the mirror body is securely fixed to the vehicle body under normal conditions. At the same time, when a human body or the like collides with the mirror body, the impact on the human body or the like can be minimized. In addition, when installing the mirror body, there is no need for work such as hooking the spring to the base as in the past, and the mirror body can be easily installed by aligning the engagement part of the wide part and pressing the mirror body. This makes it easy to install the mirror body. Furthermore, various effects can be obtained, such as adjustment of the pressure holding force of the holding member by easily filling the wide portion with an elastic material such as rubber.
