The present invention relates to the use of the 13902 No. 13 Applicant filed by the applicant, and the present application also automatically adjusts the rear or side of the vehicle to accurately see the rear or side vehicles without blind spots when changing the driving to the left or right or U-turn.

In the case of a conventional back mirror of a vehicle, the direction of the car is inclined when entering a road viewed from an interchange or a side road as shown in FIG. 1a, so that the reflecting area of the back mirror is inclined together so that the vehicle following the road is not visible. Therefore, there is a risk of collision when moving on, and when the lane changes to the left and right as shown in Fig. 1b, the reflection area is narrow so that the vehicle is not immediately visible in the rear and rear side. Accidents caused by the back-miller blind spots are frequent.

In addition, Japanese Patent Application Laid-Open No. 63-19446, although the input of the sensor and the output of the driving unit are constituted by a block diagram by the electronic control unit, it is a specific embodiment, which is unreliable in operation and cannot be put into practical use.

The present invention broadens the field of view by automatically changing the lane by installing a timer and a relay on the electric circuit of the automatic back-mirror device vehicle, and if the blinking lever is removed to the left or right side, the back-mirror is automatically opened in the opposite direction by the internal circuit. The following vehicle is to be seen well, the gist is described by the accompanying drawings as follows.

In a well-known circuit in which the left and right back mirrors are automatically adjusted up, down, left and right by driving the motors (M ₁ ), (M ₂ ), (M ₃ ), and (M ₄ ), a relay (R ₇ ) and a timer are supplied to the direction indicator power supply. (T _1), relay byeongyeol contact, (T ₁₎ of the (R ₈₎ a connecting byeongyeol the contact (R ₇₎ is connected byeongyeol the operating contacts of the left front and rear mirror (M _1), a timer (T ₁₎ is timer the relay (R ₈₎ direct thermal connection by connecting the contact point (R ₈₎ is a contact and byeongyeol of the backward Miller operation relay (R ₄₎ on and relay contact b (R _'7) of (R ₇₎ ( connected to a T ₂₎ and the byeongyeol contact point (T ₂₎ for the direct thermal connection to the forward Miller operation relay (R ₉₎ the contact point (R ₉₎ has left and right front-back direction Miller operate the motor _{(M 1), (M 3} ) It is a structure connected in parallel with the operating contact of.

Unexplained switches (SW ₁ ), (SW ₂ ), (SW ₃ ) in the drawing are manual selection switches, and relays (R ₁ ), (R ₂ ), (R ₃ ), and (R ₄ ) are mirrors up, down, left, and right. It is a relay installed in the circuit as an operation container.

The in this way the subject innovation is first switch (SW ₁₎ the motor of the upper and lower mirror around by this and the switch (SW ₂₎ selection of the left and right mirror operated by a in the main circuit _{(M 1), (M 2} ), (M 3), (M ₄ ) is driven, but in the present invention, when the flashing switch (not shown), which is the turn indicator switch, is turned on, the + power of 9 rows for lighting is turned on, and if the selection switch (SW ₃ ) is in contact, the relay ( R ₇ ) is turned on, the two contacts R ₇ of 17 rows are contacted, and the timer T ₁ is turned on.

A timer (T ₁₎ the relay (R ₈₎ is ON, and is there is disconnection in T seconds after contact with the contact point (R ₈₎ of the line 6 during T seconds of the ON relay (R ₄₎ until after T seconds by When the two contacts (R ₄ ) in the 16 rows are turned on, the working motors (M ₁ ) and (M ₃ ) of the left and right mirrors are simultaneously converted to the rearward direction.

After turning OFF the direction auto switch, 9 rows are turned off, and relay (R ₇ ), timer (T ₁ ), relay (R ₈ ) are disconnected and relay (R ₇ ) regardless of switch (SW ₃ ). When this OFF was 12 line contacts (R _'7) is opened and the contact again this time a timer (T ₂₎ contact the doemeuro relay (R ₉₎ open to T seconds after the oN contact point (R ₉₎ of the four rows are in contact two contacts (R ₉₎ of the line 17 as soon contact while the relay (R ₃₎ of the same time At this time 3 line oN contacting the 16-line contact (R ₃₎ operating the right and left mirror motor _{(M 1), (M 3} ) Is to return to rotate the forward direction.

When the angle of the mirror is bent in this way, as shown in FIGS. 2A and 2B, an unidentified blind spot generated when the vehicle is changed in the prior art is eliminated, and it is possible to safely and smoothly enter the main road or change lanes.

As described above, the present invention of the effect of the operation can ensure a safer and more comfortable operation by completely eliminating the unidentified visual area that could not be confirmed through the conventional back-mirror when changing the lane of the vehicle or driving a U-turn or curve road. It is a devising.
