Description

[Detailed explanation of the idea] The present invention relates to an interior mirror for an automobile.

This type of vehicle is equipped with a mirror body and a mirror body that supports it, but the mirror body has enough strength not only to withstand vibrations associated with normal driving, but also in the event of an accident. It is required that the

This is of course to prevent damage to the mirror body itself, but it also protects the mirror body supported by the mirror body, and prevents assembly from occurring over time, during driving, and even in accidents. This is also to prevent damage to the mirror.

Especially in Europe, standards require that mirror bodies have a certain level of strength.

In order to satisfy the strength of such a mirror body, conventionally, as shown in Fig. 1, the mirror body a is formed of a thin steel plate, and the grip part C that grips the mirror body is made of a first ring d made of ABS resin or the like. and a second ring e for reinforcement.

However, in such a configuration, both rings d. It takes time and effort to weld and fix each of the parts, and the number of parts is large, which is disadvantageous in terms of manufacturing process and parts management, and also increases the price.

In order to solve this problem, it is possible to reduce the price by manufacturing the mirror body from synthetic resin and integrating the ring as described above, but it is also possible to achieve the standard strength by using a mirror body made of polypropylene resin, for example. In this case, the thickness and shape thereof become considerably large, which is disadvantageous in terms of moldability and appearance, and is not practical.

Further, the above conventional example requires a platen (h) and a spring (i) for supporting the spherical pivot g at the tip of the stay (f), and a washer (j) for each.

k is also required, the number of parts is large, and there are many problems in terms of assembly.

In addition, in the conventional example shown in Fig. 1, it can be said that protection of the mirror body that reinforces the □lar body a is achieved, but the protection directly for the mirror body itself is not necessarily sufficient, and vibrations during driving are There is a risk that the mirror body may be damaged during assembly.

This is even more so in the event of an accident.

In view of the above circumstances, the present invention aims to lower the price and reduce the number of parts by forming the mirror body from synthetic resin, and at the same time, satisfies the strength by using a reinforced body made of metal plate, and the mirror body is integrated into the reinforced body in advance. By attaching it to the mirror body, the reinforced body directly protects the mirror body and prevents it from being damaged, and also improves the ease of assembly, especially when assembling the mirror body.Furthermore, the reinforced body □This reinforcing effect is further enhanced by directly gripping the product with the lapode.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 2 and 3, this example includes a mirror body 1, a synthetic resin □G body 2 that supports the mirror body 1, and a reinforcement body 3 that reinforces the □R body 2. The mirror body 1 is integrally attached to the reinforcing body 3 in advance and disposed on the mirror body 2, and the reinforcing body 3 is directly held by the mirror body 2. .

More specifically, the reinforced body 3 in this embodiment has 5p
It is formed from a steel plate such as CC.

As shown in FIGS. 5 and 6, this has a shape that fits the inner surface of the mirror body 2 from the side of the body, so that the reinforcing body 3 can be held directly by the mirror body 2 as shown in FIG. 3. It looks like this.

A flange portion 30 extending over the entire circumference is formed on this reinforcing body 3, and the back local portion of the mirror body 1 is adhered to the flange portion 30 using double-sided adhesive tape 4 or the like to be integrated with the flange portion 30 in advance.

As a result, the mirror body 1 is directly protected by the reinforcing body 3 before and after it is attached to the mirror body 2.

The mirror body 2 is made of polypropylene resin or the like and has a shallow box shape, the mirror body 1 is located in the front opening, and the seat 21 for receiving the spherical pivot 5 is formed in the upper part.
As a result, the stay 6 integrated with the pivot 5 is assembled to the vehicle body via the base 1 shown in FIG. 4, thereby attaching this interior mirror.

As described above, the mirror body 2 has a shallow box shape, but the front surface thereof serves as a grip portion 22 for gripping the mirror body 1, and is slightly bent inward.

To attach the mirror body 1 here, the grip portion 32 is bent outward, and the reinforcing body 3 and the mirror body 1 already attached are positioned here and fitted together.

Since the mirror body 3 is made of synthetic resin, it has elasticity, and therefore, such an arrangement can be easily performed.

As a result, the mirror body 2 is assembled with the reinforcing body 3 directly gripped by the fitting arrangement.

Since the housing mirror body 1 is integrated with the reinforcing body 3 in advance, there is no risk that the mirror body 1 will be damaged during fitting.

Furthermore, even after installation, as a result of being integrated with the reinforcing body 3, the mirror body 1 is directly reinforced and protected by this, and this also works in conjunction with the fact that the reinforcing body 3 is directly held by the mirror body 2. Therefore, there is no chance of damage caused by vibration while driving.

Furthermore, even in the event of an accident, the possibility of damage and scattering is extremely small, making it safer.

Furthermore, the edge of the mirror body 1 may be arranged so as to come into contact with the mirror body 2 to prevent rattling.

This is because even if the mirror body 2 tries to bend inward due to some external force, as a result of the above structure, no force is directly applied to the mirror body 1 itself due to the resistance force of the reinforcing body 3, and this does not cause damage.

The rattling of the reinforcing body 3 can be prevented by bringing a rattle-preventing lip 23 protruding from the mirror body 3 into contact with the reinforcing body 3, as shown in FIG.

FIG. 8 shows a modification of the above example.

In this case, the reinforcing body 3 is the rear peripheral part 11 of the mirror body 1.
The mirror body 2 is not only bonded with tape 4 but also grips the side periphery 12 of the mirror body 1, and the grip portion 22 of the mirror body 2 comes into contact with the edge layer 31 of the reinforcing body 3. , and the side periphery 32 of the reinforcing body is also in close contact with the □ g-body 2 to prevent rattling.

In this example, the prevention of rattling is more reliable than in the above example, and at the same time, the protection of the mirror body 1 is also more reliable.

As mentioned above, the automotive interior mirror of the present invention is inexpensive and easy to manufacture because the mirror body that supports the mirror body is made of synthetic resin.Moreover, since it is reinforced with a reinforced body, it can achieve the necessary strength without becoming thick or large. This is advantageous in terms of molding and appearance.Furthermore, since the mirror body is integrally attached to the reinforcing body and placed on the mirror body, assembly is easy and reliable. It is directly protected and reinforced by the body, and combined with the fact that the reinforced body is directly gripped by the Rapode, it has the effect of preventing various troubles such as damage to the mirror body later during assembly.

In the illustrated example, the spherical pivot 5 is received by the seat 21 on the upper part of the mirror body 2, which has the effect of eliminating the need for brackets and springs that were conventionally necessary.

However, it goes without saying that the automotive interior mirror of the present invention is not limited to the above embodiments.
