Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a support structure for a mirror unit in a rear view mirror for a vehicle.

[Prior Art] A typical example of this type of prior art is known from German Patent Publication No. 2813316. That is, a support frame for attaching the drive device is fixed within the mirror body, the drive device is screwed to the support frame, and then the mirror unit is attached to the front of the drive device. Since the back mirror of the type in which the mirror unit is retrofitted has poor assembly workability, recent ones prepare a subassembly in which the mirror unit 20 is attached to the drive device in advance, while the mirror unit 20 is attached inside the mirror body 21. Support frame 2 for mounting the drive unit
2, and a pair of left and right latching tongues 23 are formed at the upper part of the support frame, and a latching part 24 is formed on the drive device side at a part corresponding to the latching tongues. At the same time, the screw 26 is inserted into the hole 25 formed in the bottom wall of the mirror body from the outside of the mirror body to the threaded part 2 at the center of the lower part of the drive device.
7 (see Figure 5).

[Problems to be solved by the invention] However, the above-mentioned support frame supports the mirror unit and a drive device for changing the reflection angle of the mirror, and also has a rotating shaft to support the mirror body so that it can be tilted back and forth. Since there are sections, it is necessary to provide sufficient strength. For this reason, the support frame is generally made of a thick and sturdy material, such as a die-cast product, but in this case there are problems in that the overall weight increases and the product cost cannot be reduced. On the other hand, in addition to having sufficient strength as mentioned above, the support frame must also have a shape that matches the size of the mirror unit or drive device. There was an inconvenience that a separate support frame had to be prepared.

[Purpose of the invention] The present invention was made under the above circumstances, and its purpose is to improve assembly workability, reduce weight and manufacturing cost, and to The present invention aims to propose a support structure for a mirror unit that can sufficiently accommodate changes in the size of the unit or drive device.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a bracket that is integrally erected on a support frame provided with a retractable rotating portion of a mirror body, and a bracket that is separate from this bracket. A mirror comprising a mirror support made of a member screwed into the body, a pair of left and right hook portions formed on the support or both the support and the bracket, and a pair of left and right hooked portions on the pair of hook portions. The driving device or the mirror base is fixed to the mirror body by latching the driving device or the mirror base and passing a screw from the outside of the bottom wall of the mirror body to the center of the lower part of the driving device or the mirror base.

[Example] Hereinafter, the present invention will be specifically described based on the accompanying drawings.

FIG. 1 is an exploded explanatory view of essential parts showing an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a mirror body, and 2 denotes a support frame provided within the mirror body 1, which is made of die-casting, for example. In order to make the body 1 tiltable in the longitudinal direction of the vehicle, this support frame 2 is used by being attached to a base (not shown) attached to the vehicle body so that the support frame 2 can be freely tilted. A bearing sleeve 3 is formed to be inserted into the shaft erected on the base. A bracket 4 is integrally provided near one end of the support frame 2, and is fixed to the inner surface of the mirror body 2 with a plurality of screws 5. A hook portion 6 is formed above the bracket 4 and has a hook shape that faces diagonally upward. On the other hand, a small thin plate member separate from the bracket 4, for example a mirror support 7 made of a metal press, is fixed to the inner surface of the mirror body 2 using screws 5 in correspondence with the bracket 4. The mirror support 7 includes a hook portion 6 provided on the bracket.
A hook-shaped hook portion 8 facing diagonally upward is integrally formed.

Reference numeral 9 denotes a mirror unit, and this mirror unit is composed of a mirror 10 and a mirror holder 11 that supports this mirror from the back side. Reference numeral 12 denotes a drive device (actuator) for remotely controlling the reflection angle of the mirror 10 from inside the vehicle interior, and the mirror unit 9 is attached to the front of this drive device so as to be tiltable vertically and horizontally. The drive device 12 is provided with a pair of left and right hooked portions 13a, 13b corresponding to the hook portions 6, 8, and a threaded portion 15 of the set screw 14 is provided at the center of the lower part of the drive device 12. is formed.

Incidentally, reference numeral 16 indicates a screw hole formed in the bottom wall of the mirror body 1 in correspondence with the screw portion 15 (see FIG. 2).

In addition, in the above embodiment, a type of rearview mirror is shown that has a built-in actuator 12 for remotely controlling the mirror, but as shown in FIG. 3, the mirror unit 9 can be tilted on the mirror base 17 instead of the actuator. May be supported by
In this case, a pair of left and right hooked parts 18a, corresponding to the hook parts 6 and 8, are provided at both ends of the mirror base.
18b, and a threaded portion 19 for a set screw is formed at the lower center.

Further, FIG. 4 shows a modification of the mirror support 7. That is, in this embodiment, the main body portion of the mirror support 70 is formed from a substantially rectangular thin plate member, and a pair of left and right hook portions 20a, 20b are integrally raised at both ends thereof. This mirror support 70 is fixed to the inner surface of the mirror body 2 with screws as in the previous embodiment, but at this time, one side of the mirror support 70 is inserted into the notch 4a formed in the upper part of the bracket 4. End 7
By fitting 0a, it is positioned and fixed.

Next, how to assemble the mirror unit 9 into the mirror body 1 will be explained.

As described above, first, the support frame 2 and the mirror support 7 are fixed using the screws 5. on the other hand,
The mirror unit 9 is attached in advance to the front part of the drive device 12 or the mirror base 17 as a subassembly, and the mirror unit 9 is attached to the left and right hooked parts 13a, 13b or 1 provided at both ends of the drive device or the mirror base.
8a and 18b are hooked onto hook portions 6 and 8 formed on the bracket 4 and mirror support 7, respectively. Next, when the set screw 14 is inserted through the screw hole 16 formed in the bottom wall of the mirror body 1 and screwed into the threaded part 15 or 19 at the center of the lower part of the drive device or mirror base, the mirror unit is activated by vibrations of the vehicle body. It will not wobble when you put it on, and it will be firmly fixed in the specified mounting position.

[Effects of the invention] As is clear from the description of the above embodiments, the mirror unit support structure according to the invention has the following advantages:
The mirror support is formed from a separate member from the bracket provided on the support frame, and a pair of hook portions are formed on the mirror support or the support and the bracket, and the mirror driving device or the cover of the mirror base is attached to the pair of hook portions. Since the latching parts are latched, the support frame can be made smaller and lighter, and the mirror support does not need to be made of thick, strong material like conventional support frames. For example, it can be formed from an inexpensive pressed product or thin plate.

In addition, in the present invention, the support frame and mirror support are formed separately, so
Even when changing the size of the mirror unit or drive device, there is no need to replace the support frame; just adjust the mounting position of the mirror support with screws to match the size above, or prepare only the mirror support that matches the size. Just attach it to the specified location.

As detailed above, in addition to easy assembly according to this invention, since the support frame and mirror support are constructed as separate parts, both parts can be made smaller and lighter, and each part can be optimized. Since it can be formed from suitable materials, the manufacturing cost is also low. Furthermore, it has an effect that cannot be obtained with conventional types in that it can easily accommodate changes in the size of the mirror unit or its driving device.
