Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention applies to any one of a plurality of drive motors of an electric remote control mirror.

It relates to an operation switch for reversibly operating the switch, and includes a plate spring-shaped sliding electrode having sliding contacts at both ends, a wiring board having fixed contacts corresponding to the sliding contacts, and a wiring board that comes into contact with the sliding contacts. A switch for remote control mirror operation, which is equipped with a push plate having a tapered surface that presses it toward a fixed contact, and a double-throw switch for switching left and right of the mirror drive circuit, which is configured separately from the above. It is related to.

[Background of the invention]

Remote control mirrors are used in cars etc.
It is equipped with multiple motors to rotate the reflective surface up and down and left and right. Therefore, the switch for operating the remote control mirror needs to have a function of operating any one of the plurality of motors in the forward and reverse directions.

In order to make the above operations possible with a single switch device, a tilting device for an electric remote control mirror is known from Japanese Utility Model Application No. 58-40451.

This invention was created and filed by the inventor of the present application, and to further summarize the gist of its structure, it consists of a leaf spring-shaped sliding electrode with sliding contacts at both ends, and a fixed contact corresponding to the sliding contact. A push plate having a tapered surface that comes into contact with the sliding contact and presses the fixed contact is provided, and a double-throw switch is provided separately from the above. .

6 to 9 are explanatory diagrams of the operating principle of the switch device according to the above-mentioned known technology.

1 is a housing, and 2 is a push button-shaped push plate.

A wiring board 3 is attached to a housing 1, and a contact group (left) 4 and a contact group (right) 5 are provided on its surface (lower surface in the figure). Each of these contact groups consists of three contacts, and these are fixed contacts (tomokuni) 4a, same (blood) 4b, same (leftward) 4c, and fixed contacts (overseas) 5.
Name them a, 5b (in the cloth), and 5c (towards the right).

A sliding contact 6a corresponds to the above two groups of fixed contacts.

A plate spring-shaped slide electrode 6 is configured with electrodes 6b at both ends. This slide electrode is curved and is provided with an auxiliary spring 6c to supplement its spring elasticity.

A pair of legs 2a, 2b are formed on the back side (upper side in the figure) of the push plate 2, and tapered surfaces 2a-, 2b- are provided at the tips thereof. The plate spring-like sliding electrode 6 is elastically restoring to the sliding contacts 6a, 6 at both ends.
b is the above-mentioned tapered surface 2a-.

2b-1.

As shown in Fig. 6, when no operating force is applied to the push plate, the left and right sliding contacts 6a+6b contact and conduct with the fixed contacts (in the blood) 4b and 5b (in the cloth), respectively. There is.

When the left end of the push plate 2 is pushed as indicated by arrow A in FIG. 7, the Taber surface 2a-1 pushes the sliding contact 6a to the right in the figure, and the Taber surface 2b-1 pushes the sliding contact 6a to the right in the figure.

moves in the direction to retreat from the sliding contact 6b (to the right in the figure), so the sliding electrode 6 slides to the right in the figure, and along with this, the fixed contact (leftward) 4c and the same (overseas) 5a is bridged by the slide electrode 6.

Conducted.

For the same reason, when the right end of the push plate 2 is pushed, the slide electrode 6 is slid to the left in the figure, as indicated by the arrow B indicated by the imaginary line in FIG.
4a and the same (rightward) 5c are electrically connected.

FIG. 9 shows one example of the known switch device described above.
The push plate 2 is installed with its rectangular surface vertical, as shown in a perspective view with a section cut away.

With this configuration, U, D of push plate 2,
When either one of the L and R sides is pushed, the left and right slide electrodes 6, 6' operate as shown in Table 1 below. However, in Table 1, the same conductive state as in FIG. 6 is indicated by ■, and arrow A in FIG.
The conduction state when the arrow B in the figure is pressed is represented by [phase], and the conduction state in FIG.

(Table 1) Figures 6 to 9 explain the operating principle. For example, contact group (left) 4 has three fixed contacts (overseas) 4a + same (inside) 4b, same (left side) 4c, by applying this principle, for example, of the three fixed contacts, (overseas) 4a and (inside) 4b may be integrally connected and electrically connected.

In the above-mentioned Japanese Patent Publication No. 58-40451,
As shown in FIG. 9, an opening 2c is provided in the center of the push plate 2, and a double-throw switch 7 is provided in the housing 1 as shown in FIG.
' and a double-throw switch 7 are connected, for example, as shown in FIG. 11, to operate the left mirror drive motor group B and the right mirror drive motor group C.

B-, left side mirror left and right drive motor, B-, left side,
The motor for vertically driving the side mirrors, C-1 is the motor for horizontally driving the right side mirror, and C4 is the motor for vertically driving the right side mirror. By operating these four motors in forward and reverse directions, the directions of the left and right mirrors can be adjusted vertically and horizontally.

In the operation circuit of this known example (FIG. 11), the upper side U, lower side, and left side of the push plate 2.

By selectively pushing the right side R, the mirror is tilted upward, downward, leftward, and rightward, and the double-throw switch 7 (in this example, a double-pole double-throw switch) is operated. This structure allows switching between the left and right motor groups B and C.

Reference numerals 6 and 6' shown by virtual lines are left and right slide electrodes, and the members shown with hunting at the upper and lower ends represent fixed contacts.

For example, a-+ of the fixed contact group in the upper left corner of the figure is a fixed contact corresponding to the inner fixed contact in the principle diagram of FIG.
-t is a fixed contact corresponding to the outer fixed contact and the central fixed contact connected together. One point without hunting located in the center of these fixed contacts az indicates an opening, and in the principle diagram (Figure 6), the tapered surfaces 2a-, 2b
-1 is provided so as not to obstruct the entry of the legs 2a and 2b.

In addition, in this example, fixed contacts a-5, a-h and a-4+ a-? The fixed contacts shown in the principle diagrams (FIGS. 6 to 8) are partially divided to open and close the left and right mirror motor circuits.

In this Fig. 11, the fixed contact a shown with a dash
-i and a-i are respectively fixed contacts a -It a-2
is permanently connected and conductive.

In the operating circuit of FIG. 11, the U of the push plate,
When each side of D, L, and R is selectively pushed, each motor B-+, B-*, C-r, and C-z has the first
As shown in Figure 2, positive and negative voltages are conducted.

D-410-? is a diode provided to prevent reverse current flow.

As can be easily understood from FIGS. 11 and 12, the top of the push plate 2 in this known example.

By selectively pushing the bottom, left, and right sides U, D, L, and R, the mirror can be rotated upward and downward.
Switch the conduction to rotate leftward or rightward, and then use the double-throw switch 7 to turn the mirror group B on the left.
The structure switches between the operating circuit for the mirror group C on the right side and the operating circuit for the mirror group C on the right, and for this reason, providing a double-throw switch is an essential component.

However, as shown in FIG. 10, since the double-throw switch 7 is installed inside the housing 1, the thickness T of the housing 1 becomes large. This makes it difficult to match the installation location when installing.

[Purpose of the invention]
