Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention provides a mirror body that stands up on a mounting base that is attached to the left and right doors of a vehicle.
This invention relates to a drive circuit for a foldable door mirror that is assembled so that it can be folded down.

[Prior Art] In general, the left and right side door mirrors of a car protrude more outward from the car body than the fender mirrors, so when entering a garage or multi-story parking lot, for example, the door mirrors get in the way and make it difficult to enter the car smoothly. , damage to door mirrors or equipment in garages and multi-storey parking lots. Therefore, we have developed a foldable door mirror that can lower the mirror body from its upright position to reduce the amount of protrusion if necessary. have been developed in various ways.

[Problems to be Solved by the Invention] However, in conventional devices of this type, the left and right mirror bodies must be held and operated directly with each hand when folding them down or standing them up. It is necessary to get out of the car or open the window each time, and it is of course troublesome to operate the driver's side door mirror, but it is especially difficult to operate the passenger side door mirror when there are no passengers other than the driver. However, there were problems such as being extremely unstable and inconvenient to handle, especially on rainy or snowy days or during cold seasons. For this reason, efforts have been made to make it possible to raise and lower the left and right mirror bodies electrically. For example, when both the left and right mirror bodies are upright, only one of them can be laid down, or when both the left and right mirror bodies are laid down, only one of them can be laid down. There were problems such as not being able to

This invention solves the above-mentioned problems of the conventional ones, and allows the left and right door mirrors to be raised and lowered electrically.Moreover, the left and right mirror bodies can be arbitrarily selected and raised and lowered by electrical operation. The purpose of this invention is to provide a drive circuit for a foldable door mirror that can be used.

[Means for Solving the Problems] In order to achieve the above object, the first aspect of the present invention is that a mirror body is assembled to a mounting base attached to the left and right doors of a vehicle so as to be able to stand up and fall down, respectively. In the attached foldable door mirror,
There is an automatic return type push button switch installed inside the vehicle interior and dedicated to the left and right side door mirrors to raise and lower them independently, a reversible motor installed inside the left and right mirror bodies, and a a plurality of limit switches that are respectively attached to the base mounting portion and operate when each mirror body is in the upright or down position to detect the upright or down position of the mirror body; relays for upright and down position; and the push button. The present invention is characterized by comprising a switching means for selecting operation of the reversible motor for left and right door mirrors by a switch.

Further, the second invention replaces the button switch in the first invention with a seesaw button switch, and adds a self-holding circuit for sustaining standing up and falling down.

[Function] When the left and right door mirrors, or either one of them, is in the upright position or between the upright position and the collapsed position, each door mirror can be operated independently by pressing the dedicated automatic return push button switch for the left and right door mirrors. Rotate to the prone position. Furthermore, when the door mirrors are in the folded position, pressing the push button switch allows each door mirror to be returned to the upright position.

[Example] Hereinafter, an example of the present invention shown in the drawings will be described.

FIG. 1 shows an embodiment of the present invention, in which an automobile 1
The mirror bodies 5L, 5R are attached to the mounting bases 3L, 3R attached to the left and right doors 2L, 2R via shafts 4L, 4R so as to be rotatable around the shafts 4L, 4R. Alternatively, the mirror bodies 5L, 5R are provided with reversible motors ML, MR, and the rotation of the reversible motors ML, MR moves the mirror bodies 5L, 5R to the upright position N shown by the solid line via the gears 6L, 6R and the gears 7L, 7R. ,
It is designed to move between a lodging position (rearward position) B indicated by a chain line. The mounting bases 3L and 3R are also equipped with limit switches that detect when the mirror bodies 5L and 5R are in the upright position N.
LSLN, LSRN, and limit switches LSLB, LSRB that detect when the mirror bodies 5L, 5R are in the inverted position B are provided. In the above description, the letter L refers to the left side, and the letter R refers to the right side. As shown in FIGS. 2a and 2b, inside the vehicle 1, a push button switch (or seesaw button switch) BS and a changeover switch SW are housed in a common case 8, and the driver's seat The changeover switch SW has two positions, L and R, as shown in Figure 2a, and a switch SW that can be operated from L and R, as shown in Figure 2b.
As shown in the figure, there is a type that can switch between three positions: L, N, and R. The automobile 1 also includes a drive circuit (indicated by DC in FIGS. 3 to 7) that selectively raises and lowers the left and right mirror bodies 5L and 5R by operating a push button switch (or seesaw button switch) BS and a changeover switch SW. .) is provided.

FIG. 3 shows an embodiment of the drive circuit DC.
Figures a to d are the same except for the changeover switch SW circuit.
First, the drive circuit DC shown in FIG. 3a will be explained. Figure 3a uses the L and R changeover switch SW of Figure 2a, and the pushbutton switches BS ₁ and BS ₂ are the same as the pushbutton switches BS of Figure 2a.
It is an automatic return type that closes the circuit between the contacts only while the limit switch LSLN,
The LSRN detects this only when the mirror bodies 5L and 5R are in the upright position N and opens the contacts, and otherwise always closes the contacts.
The limit switches LSLB and LSRB detect the mirror bodies 5L and 5R only when they are in the collapsed position B and open the contacts, and otherwise keep the contacts closed at all times.
When current flows from terminal N to terminal B, mirror bodies 5L and 5R are moved from upright position N to laid down position B, and when current flows from terminal B to terminal N, mirror bodies 5L and 5R are moved to laid down position B. The robot is moved from the position N to the standing position N. Contact xB is NO only when XB is energized
A single-pole relay that closes the circuit and keeps the NC circuit closed at all other times.
A single-pole relay that keeps the circuit closed at all times, Tr is a transistor, r ₁ and r ₂ are resistors, and D ₁ to _{D 9} are diodes.

This drive circuit DC operates as follows.

b) When the changeover switch SW is in the L position: First, when the mirror body 5L is in the upright position N (or between the upright position N and the collapsed position B), the push button switch BS (i.e., BS ₁ , BS ₂ )
When pressed, relay XB is energized via the NC circuit of contact xN, so that current flows through the NO circuit of contact xB and the L circuit of changeover switch SW to limit switch LSLB and diode D ₉ via diode D ₇ . At the same time, the cathode side of diode _D7 becomes a positive voltage,
PNP transistor through pushbutton switch BS ₂ which is closed in conjunction with pushbutton switch BS
Since positive voltage is applied to the base of Tr, transistor Tr is not conductive and relay XN is not energized, which causes relay
Reversible motor while self-held through circuit
Current flows from terminal N to terminal B through the _NC circuit of contact xN, which causes the mirror The body 5L is moved toward the laid down position B. When the mirror body 5L reaches the laid down position B, the contact of the limit switch LSLB is opened, so the reversible motor ML is de-energized, the mirror body 5L stops moving, and is moved to the laid down position B by an appropriate mechanical means (not shown). held, while relay XB is demagnetized. Then, when the mirror body 5L reaches the lodging position B,
Due to its inertia, the reversible motor ML, which had been energized until then, does not stop instantly even if the contact of the limit switch LSLB is opened, and as it rotates, it generates an electromotive force and a positive potential at the terminal N, which demagnetizes the relay XB. The timing is delayed,
As a result, even if the contact of the limit switch LSLB is opened, the bias voltage necessary for conduction is applied to the emitter of the transistor Tr via the contact xB, which still closes the NO circuit, and at this time, the electromotive force of the reversible motor ML decreases. When the base potential of the transistor Tr suddenly drops to the potential required for conduction, the transistor Tr becomes conductive and the relay XN is energized. The current flows and the mirror body 5L moves towards the upright position N again, but the base of the transistor Tr and the reversible motor ML are connected by the action of the pushbutton switch _BS2 , which opens when the pushbutton switch BS is released. terminal N
Since the transistor Tr is not conductive and the relay XN is not excited, the mirror body 5L is held in the inverted position B.

Next, when the mirror body 5L is in the folded position B, the pushbutton switches BS (i.e., BS _{1 ,} BS 1 ,
BS ₂ ), relay XB is energized via the NC circuit of contact xN, and therefore NO of contact xB
A positive voltage is applied to the emitter of the transistor Tr through the circuit, and the transfer switch
Limit switch connected to SW's L circuit
Since LSLB is open, the cathode side of diode D ₇ does not have a positive voltage, and the ground potential is applied to the base of transistor Tr via resistor r ₁ and push button switch BS ₂ , which is closed in conjunction with push button switch BS. Therefore, transistor Tr becomes conductive, relay XN is energized, and the contact
xN switches from NC side to NO side, relay XB is demagnetized, and relay
NC circuit of contact xB of relay XB which is self-held via NO circuit, limit switch LSLN and diode D ₅ , while reversible motor ML is demagnetized by diode D ₃ and contact xN of relay XN switching to NO side A current flows from the terminal B to the terminal N through the mirror body 5L, thereby moving the mirror body 5L toward the upright position N.
When the mirror body 5L reaches the standing position N,
Since the contact of the limit switch LSLN is opened, the reversible motor ML is de-energized, and the mirror body 5L stops moving and is held at the upright position N by appropriate mechanical means, while the relay XN is demagnetized.

(b) When the changeover switch SW is in the R position: During the explanation of (a) above, the limit switch
LSLB, LSLN limit switch LSRB,
If the diodes D ₁ , D ₃ , D ₅ , and D ₇ are replaced with the diodes D ₂ , D ₄ , D ₆ , and D ₈ in LSRN, the above explanation (a) will apply. Figure 3b uses the L, N, R changeover switch SW in Figure 2b, and when the changeover switch SW is in the L or R position, it operates in the same way as in Figure 3a; When in the N position, the pushbutton switch BS (i.e. BS ₁ ,
By pressing BS ₂ ), relay XB connects contact xN.
Even if the voltage +12V is applied to the COM terminal of the changeover switch SW through the NO circuit of the contact xB after being energized through the NC circuit, the changeover switch SW remains open circuit, so the
Both MRs are to be kept inactive.

FIG. 3c also uses the L, N, R changeover switch SW of FIG. 2b, and when the changeover switch SW is in the L position or R position, it operates in the same way as FIG. In addition, when in the N position, the push button switch BS (i.e. BS ₁ , BS ₂ )
By pressing , relay XB is energized via the NC circuit of contact xN, and a voltage of +12V is applied to the COM terminal of the changeover switch SW via the NO circuit of contact xB.
is applied, a current flows through the N circuit of the changeover switch SW, the relay XS and the NC circuit of the contact xN, which excites the relay XS and closes both the contacts xS ₁ and xS ₂ . The situation is similar to when the result changeover switch SW is in the L position and the R position at the same time. That is, when the changeover switch SW is in the N position, this drive circuit DC operates as follows.

First, the mirror bodies 5L and 5R are in the standing position N.
(or between the upright position N and the collapsed position B), the pushbutton switch BS (i.e. BS ₁ ,
BS ₂ ), relay XB is energized via the NC circuit of contact xN, and therefore NO of contact xB
_Limit switch _LSLB ,
LSRB, diodes D ₇ , D ₈ and diodes
Current flows through _D9 and relay XB is self-held, while reversible motors ML and MR are connected to diodes _D1 ,
D ₂ (When the mirror bodies 5L and 5R are between the upright position N and the collapsed position B, the limit switch
A current flows from the terminal N to the terminal B through the NC circuit of the contact xN (LSLN, LSRN), and the mirror bodies 5L and 5R are thereby moved toward the collapsed position B. When mirror bodies 5L and 5R reach the lodging position B, the limit switch
Since the contacts of LSLB and LSRB are open, the reversible motors ML and MR are de-energized and the mirror body 5
L and 5R stop moving and are held in the laid down position B by suitable mechanical means, while relay XB is demagnetized. In this process, if one of the mirror bodies (for example, 5L) reaches the collapsed position B first, the contact of the limit switch LSLB is opened and the mirror body 5L is stopped and held at the collapsed position B, but the diode D Since the relay XB continues to be self-held through the mirror ₈ , the reversible motor MR continues to be energized and the mirror body 5R is moved to the folded position B. The same applies when the mirror body 5R reaches the collapsed position B first.

Next, when the mirror bodies 5L and 5R are in the folded position B, the push button switch BS (i.e.
BS ₁ , BS ₂ ), relay XB closes contact xN.
energized via the NC circuit and therefore contact xB
A positive voltage is applied to the emitter of the transistor Tr via the NO circuit, and since the limit switches LSLB and LSRB are both open, the cathode side of the diodes _D7 and _D8 does not have a positive voltage, and the resistor _r1 and the pusher button switch
Push button switch BS ₂ that is closed in conjunction with BS
Since the ground potential is applied to the base of transistor Tr through NO circuit of contact xN, limit switch LSLN, LSRN and diode
The reversible motors ML and MR are self-held via D ₅ and D ₆ , while the reversible motors ML and MR are connected to diodes D ₃ and D ₄ and relays.
Current flows from terminal B to terminal N through the NC circuit of contacts xS ₁ and xS ₂ which are closed due to the excitation of XS, and contact xB of relay XB which is demagnetized by switching to the NO side as contact xN of relay XN is switched to the NO side. Thereby, the mirror bodies 5L and 5R are moved toward the upright position. When mirror bodies 5L and 5R reach the standing position N, the limit switch
Since the LSLN and LSRN contacts are open, the reversible motors ML and MR are de-energized and the mirror body 5
L and 5R stop moving and are held in the upright position N by suitable mechanical means, while relay XN is demagnetized. In this process, if one of the mirror bodies (for example, 5L) reaches the standing position N first, the contact of the limit switch LSLN is opened and the mirror body 5L is stopped and held at the standing position N, but the diode D Since the relay XN continues to be self-held through ₆ , the reversible motor MR continues to be energized, and the mirror body 5R is moved to the upright position N, then stopped and held. The same applies when the mirror body 5R reaches the collapsed position B first.

Further, when only one of the mirror bodies 5L and 5R (for example, 5L) is in the folded position B, the push button switch BS (i.e., BS ₁ , BS ₂ )
When pressed, relay XB is energized via the NC circuit of contact xN, so contact xS ₂ is closed due to the NO circuit of contact xB and the energization of relay XS.
Current flows through limit switch LSRB and diodes D ₈ and D ₉ to self-hold relay XB, while reversible motor MR flows through diode D ₂
(When mirror body 5R is in the standing position N)
Or limit switch LSRN (when the mirror body 5R is between the upright position N and the down position B) and the terminal N via the NC circuit of the contact xN.
A current flows from the terminal B to the terminal B, and the mirror body 5R is thereby moved toward the collapsed position B. When the mirror body 5R reaches the laid down position B, the contact of the limit switch LSRB is opened and the mirror body 5R is stopped and held at the laid down position B.
The same applies when only the mirror body 5R is in the folded position B.

FIG. 3d also uses the L, N, R changeover switch SW of _{FIG .} When pressed, relay XB is energized via the NC circuit of contact xN, and the changeover switch is activated via the NO circuit of contact xB.
When voltage +12V is applied to the COM terminal of SW,
Current flows through the L circuit of the changeover switch SW, the relay XL and the NC circuit of the contact xN,
As a result, relay XL is energized and contact xL is opened, and as a result, contact xB is COM
The terminal and the terminal of the limit switch LSLB are connected, and the changeover switch SW is set to R.
position, press the pushbutton switch BS (i.e. BS ₁ , BS ₂ ) to switch the changeover switch SW.
When a voltage of +12V is applied to the COM terminal, current flows through the R circuit of the changeover switch SW, through the NC circuit of relay XR and contact xN, which energizes relay XR and opens contact xR, resulting in The COM terminal of contact xB and the terminal of limit switch LSRB will be connected only through the closed contact xL of relay XL, which is not energized, and in either case, the operation will be the same as in Figure 3a. . Also, the changeover switch
When the SW is in the N position, the pushbutton switch
Even if voltage +12V is applied to the COM terminal of the changeover switch SW by pressing BS (i.e. BS ₁ , BS ₂ ), both relays XL and XR are not energized, so contacts xL and xR both remain closed, Therefore, in Fig. 3c, the changeover switch
It will be in the same state as when SW is in the N position and will operate in the same way.

The COM terminal of the contact xB and the terminal of the limit switch LSLB are connected through the mirror only, so that only the reversible motor ML is energized and only the mirror body 5L is raised or lowered. Also, when the changeover switch SW is in the R position, press the pushbutton switch BS (i.e. BS ₁ , BS ₂ ) to apply a voltage of +12V to the COM terminal of the changeover switch SW.
When applied, current flows through the R circuit of relay XR and changeover switch SW and through the NC circuit of contact xN, which energizes relay As a result, the COM terminal of contact xB and the terminal of limit switch LSRB are connected only through the NC circuit of contact xL of relay XL, which is not energized, so that only reversible motor MR is energized and only mirror body 5R is raised or lowered.
