Description

[Detailed description of the invention] This invention relates to an automobile mirror device that is installed on the car body.In particular, it can be used in two positions, such as mirroring the sides of the car body, which previously only reflected the rear side of the car body. It is an object of the present invention to provide an extremely practical automobile mirror device which can be improved to be much more convenient, much safer, and also have a good appearance.

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. It is a mirror device, and 3 is a support which is a supporting part thereof, and 4 is a main body part.

The support column 3 is installed in a fixed state on the front fender part 1a, and in detail, as shown in FIG. It has a hole 7 which passes through the hole 6 in the radial direction and communicates with the hole 5, into which a lead wire bundle 8 for supplying power to two motors, electromagnets, etc., which will be described later, is inserted.

On the other hand, the main body 4 has a lower cover 9 and an upper cover 10 that also serves as an edge cover as outer shells, and the lower cover 9 is connected to the shaft 1 through a spring washer 11.
2 is rotatably inserted through the shaft 12, and the distal end of the shaft 12 is inserted into the hole 6 of the support column 3 and is fixed in a non-rotatable manner by a pin 13 inserted into the hole 7, whereby the non-rotatable shaft is inserted. 12, the lower cover 9 is rotatably mounted and supported on the support column 3.

The upper flange 12a at the upper end of the shaft 12 has a gear 14 formed by cutting out a part of the circumference and chamfering stopper parts 14a and 14b on both sides thereof, and two protrusions 15a located above the gear 14. , 15b and a cam 15 having a predetermined angle apart from each other are commonly attached by a screw 16, so that the gear 14 and the cam 15 do not rotate either.

Further, on the lower cover 9, an electromagnet device 20 is installed, which consists of a coil 17, a plunger 18 attracted by the coil, and a spring 19 that normally pushes the plunger 18 toward the side opposite to the coil 7. cover 9
As shown in the figure, in a state where the gear 14 is engaged with one stopper part 14a, the claw part 18a at the tip of the plunger 18 is engaged with a part of the teeth of the gear 14 by the pushing force of the spring 19. The lower cover 9 is restrained from rotating.

Incidentally, 21 is a gear 14 to prevent rotation of the plunger 18.
This is a plate attached to the tip of the plunger 18 facing toward the upper surface.

In addition, 22 is a reducer mounted on the lower cover 9 alongside the electromagnetic device 20, and its output gear 23 is meshed with the gear 14. On the other hand, the motor 2 is mounted on the reducer 22.
4 and two normally closed switches 25 that are position detection switches.
．． 26 and the lower cover 9 is engaged and restrained by one stopper portion 14a of the gear 14 as described above, the switch 25, 26 is also attached to one protrusion 15a of the cam 15. Among them, the actuator 25a of the switch 25 is pressed in a corresponding manner, and thereby the switch 2
5 is open.

Furthermore, as shown in Fig. 5, diodes 27 and 28 are connected in parallel to the switches 25 and 26 with the polarities shown, respectively. A double switch 29 is shown, to which the aforementioned motor 24 and coil 17 are connected via the aforementioned switches 25 and 26, respectively, as shown.

Furthermore, 30 is a support plate 3 together with a remote control unit 31.
2, which is housed inside the upper cover 10 which is attached to the lower cover 9 to cover each of the above-mentioned parts.
Thereafter, the support plate 32 is fixed to the lower cover 9 with screws 33, thus completing the entire assembly.

Now, in the case of this embodiment configured as described above, the lower cover 9 is brought into engagement with one stopper portion 14a of the gear 14 as described above, and is restrained from rotating by the plunger 18 of the electromagnet device 20. Now that one protrusion 15a of the cam 15 presses the actuator 25a of the switch 25 to open the switch 25, the main body 4, of which the lower cover 9 is part of the outer shell, also moves normally against the support column 3. Therefore, in this position, the mirror 30 reflects the rear of the vehicle body 1 as shown by arrow C in FIG. 1, and the angle of the reflection can be set as desired by the remote control unit 31.

Next, from this state, when both the dual switches 29 are operated to close the S□ side, the connection is made through the diode 27 which replaces the open switch 25 as described above and the switch 26 which remains in the closed state. The motor 24 and the coil 17 are energized, and the electromagnetic device 20 attracts the plunger 18 and separates it from the gear 14, thereby releasing the restraint of the lower cover 9 and the main body 4, while the power of the motor 24 is decelerated. By transmitting the signal to the machine 22 and driving its output gear 23, the output gear 23 rolls around the gear 14 in a meshed state, and as a result, the main body 4 moves in the direction of arrow A in FIG. Rotated.

Then, instead of the switch 25 being closed from the actuator 25a pressed by the one protrusion 15a of the cam 15, the switch 26 is opened by the actuator 26a being pressed by the other protrusion 15b of the cam 15. Therefore, at this point, the motor 24 is also cut off and the rotation of the main body 4 is stopped, and the coil 17 is also cut off, releasing the plunger 18 from suction, and thus being released. The plunger 18 protrudes under the elastic force of the spring 19, and therefore, the lower cover 9 engages the claw portion 18a with the gear 14 which has changed from engaging with the one stopper portion 14a to the other stopper portion 14b. to restrain the main body part 4.

Now, the main body part 4, which has been rotated and stopped in this way and is further restrained and held, is shown in the mirror 30 in the state shown by the two-dot chain line in FIG.
As shown by the arrow in the figure, the side (right side) of the vehicle body 1 is reflected.On the other hand, although not shown, the mirror device here is also symmetrical and similar on the left side of the vehicle body 1. Therefore, the mirror reflects the left side of the vehicle body 1.

Furthermore, when the double switch 29 is then operated to close the S2 side, everything works in the complete opposite manner to that described above, so that the main body 4 rotates in the direction of arrow B in FIG. The state returns to the state shown in , that is, the state in which the mirror 30 reflects the rear of the vehicle body 1, and the electromagnetic device 20 retains this state in a power-off state.

In addition, switches 25 and 26 are both closed between the position where the rear side of the vehicle body 1 is shown and the side view shown above, so that the main body 4 can be moved from this position to the above-mentioned two positions. It can be rotated in either direction.

As described above, according to this embodiment, the main body 4 of the mirror device 2, which is located at the front of the vehicle body 1 and normally reflects the rear of the vehicle body 1, is moved to a position where the sides of the vehicle body 1 are reflected by remote control as necessary. It can be rotated, and this makes it very convenient to see cars coming from the side at crossroads and T-junctions, and also prevents people from entering the intersection carelessly. There are also things that can be done and made very safe.

By the way, conventionally, if only the side view of the car body 1 was to be reflected, a dedicated mirror device was attached to, for example, the tip of the bonnet, separately from the mirror device for reflecting the rear side of the car body 1. This thing doesn't look good.
This severely damaged the appearance of the car.

In this regard, according to this embodiment, since the mirror device 2 that originally reflects the rear of the vehicle body 1 can be used as it is to reflect the side of the vehicle body 1, there is no need for anything else. Unlike conventional ones, it can maintain a good appearance, and of course does not spoil the overall appearance of the car.

Further, in the above embodiment, when the main body 4 reaches either the position where the side view of the vehicle body 1 is shown or the position where the rear view is shown, the switches 25 and 26 are opened at each limit position, and the motor 24 is opened. In addition to being configured to cut off power to the electromagnetic device 20, the electromagnet device 20 is also configured to restrain the main body portion 4 in a de-energized state, which not only prevents unnecessary energization but also prevents the occurrence of a restraint burnout accident. There are benefits to be gained.

In addition, as an effect peculiar to the above embodiment, in the electromagnet device 20, when a human body or an object hits the main body part 4, the restraint of the main part 4 is released, and the plunger 18 is elastically held by the spring 19. Damage to property can be prevented, and in this case, the orientation of the main body 4 can be maintained so that it does not change due to vibrations or wind force while the vehicle is running.

However, the present invention is not limited to the embodiments described above and shown in the drawings, and therefore, the specific configuration of the electromagnet device 20 may be modified as appropriate without departing from the spirit of the invention.

In summary, the present invention is an automobile mirror device in which a main body including a mirror is rotatably supported between two positions with respect to a support fixed to the vehicle body, and the main body is supported rotatably between two positions. A motor for rotating between the above three positions,
An electromagnetic device that restrains the rotation of the main body relative to the support portion in at least the above two positions in a de-energized state, and an electromagnetic device installed in the vehicle interior that releases the restraint of the main body and activates the motor. It is equipped with a switch that turns the main body by applying electricity, and a position detection switch that detects when the main body reaches one of the above two positions and cuts off the electricity to the motor and electromagnet device. This feature makes it extremely convenient and extremely safe, as well as ensuring a good appearance, as well as avoiding wasteful consumption of battery power and preventing the occurrence of restraint burnout accidents. It has many excellent practical effects, including the ability to prevent
