[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an operation unit that executes window selection and lifting / lowering operation instructions for a plurality of power windows of an automobile.
[0002]
[Prior art]
Most door-windows of automobiles can be opened and closed, and there are two types of opening / closing mechanisms, one for manually raising and lowering the handle and the other for driving by the rotation of a motor. Recently, the latter type, that is, a vehicle employing a power window has become the mainstream, and a control operation unit that can open, close, or lock all door windows around the driver's seat is installed. This control operation unit generally has a number of operation switches corresponding to all windows and a window lock switch for prohibiting individual opening and closing in the rear seat and the passenger seat. For example, the motor of each window has a circuit configuration as shown in FIG. 6 (the AUTO circuit is omitted), and the corresponding window is driven by selecting a corresponding switch and performing UP / DOWN operation. It is like that. In the state shown in the figure, both the UP side terminal and the DOWN side terminal are connected to the ground, and are in a so-called locked state. Incidentally, in order to open the window on the left side of the rear seat in the figure, first select the corresponding switch and operate the knob to the DOWN side. Then, the positive voltage is applied to the right DOWN terminal and the left UP terminal remains connected to the ground, so that a voltage is applied between both terminals, current flows from the right terminal to the left terminal of the motor, and the motor is rotated forward. open. If the knob is released when the desired amount is opened, the state returns to the state shown in the figure and the motor stops. When you want to close the open window, if you move the knob of the corresponding switch to the UP side, the right DOWN terminal is held at ground potential and the left UP terminal is connected to the positive electrode of the battery. This time, current flows from the left side of the motor to the right side, reverses the motor and closes the window. In this way, the power window control switch is configured to require as many lift switches as the number of windows.
[0003]
In addition to this power window switch, the operation switch placed around the driver's seat also requires an electric mirror drive switch and door lock switch, where compactness and ease of operation are required. is there. For example, Japanese Patent Application Laid-Open No. 9-161612, Japanese Patent Application Laid-Open No. 11-96853, and the like have been proposed corresponding to this downsizing. In JP-A-9-161612, as shown in the plan view of FIG. 7A, the open / close circuits of the left and right windows of the front seat and the rear seat of the vehicle are selected by operating one rotation operation knob 3. Thus, this is combined with an automatic opening / closing operation knob 4 and a door lock operation knob 5 common to each window to constitute one master switch. The rotation operation knob 3 can be moved up and down with rotation, and the switching operation of the open / close circuit of each window is possible at the upper position, but when it is at the lower position, the circuit cannot be selected and locked. It has become. Apart from the door lock operation knob 5, there are two knobs used for window opening / closing control, which is more compact than a conventional configuration comprising a combination of lift switches and lock switches for the number of windows. It has been.
Japanese Patent Application Laid-Open No. 11-96853 presents a multi-function control panel that combines a power window operation switch and an electric mirror operation switch as shown in a perspective view in FIG. 7B. In other words, the switch box 11 has a multi-directional switch 12, a push button type mode switch 13, a lift switch 14 for instructing to lift the window, a mirror L / R selection switch 15, a mirror retract switch 16, a door lock. An / unlock switch 17 and a window lock switch 18 are incorporated. First, the multi-directional switch 12 operates to open and close the nine contacts by tilting the operation rod 20 in all directions or pressing it downward. However, when the window operation is selected by the mode change switch 13, the operation switch 20 is operated. When 20 is pressed downward, four windows are selected, and when tilted to any of the eight sides, two front parts, one left front part, two left parts, and left rear part corresponding to the position. One sheet, two rear parts, one right rear part, two right parts, and one right front part are selected. This device is used not only for window operation but also for the mirror control and door lock control operation part, and as a whole it is designed to be multi-functional and compact. However, focusing on power window control, multi-directional switch 12 and mode switch 13, there is a raising / lowering switch 14 and a window lock switch 18, and there is convenience in selecting various correspondences, but it cannot be denied that the operation is complicated.
[0004]
[Problems to be solved by the invention]
For the problem of downsizing the operation part of the power window arranged around the driver's seat, the prior art as described above has been presented, but when looking at specifying the window and opening and closing operation of the specified window, Japanese Patent Application Laid-Open No. 9-161612 discloses a method for opening and closing a window by operating an automatic opening / closing operation knob 4 after turning and specifying a turning operation knob for selecting a target window. In the case of the publication No. 96853, first, the mode changeover switch 13 is operated to set the power window operation mode, then the operation window 20 of the multi-directional switch 12 is operated to identify the target window, and the lift switch 14 is operated to open the window. Open and close. In any case, the windows are opened and closed by operating a plurality of operation units.
Accordingly, an object of the present invention is to solve these problems of the prior art, that is, to reduce the size of the operation unit, and to operate a plurality of windows by operating only one knob without moving hands to different operation units. It is an object to provide a power window control operation unit capable of executing identification and opening / closing driving thereof.
[0005]
[Means for Solving the Problems]
A power window control operation unit according to the present invention includes a mechanism for selecting and specifying a target to be driven among a plurality of windows by short-circuiting or opening terminals according to a slide position of a knob unit having a short-circuit member, and the knob unit. When the knob unit is in the neutral position, all windows are controlled regardless of the knob operation. The circuit was cut off so that no voltage was applied to the motor.
In addition, the power window control operation unit of the present invention is provided with conductive bands and power input terminals arranged at different positions in the vertical direction with respect to the slide surface around the knob unit, and is placed at a position corresponding to each window. By making contact with the terminals facing each other, flexible lead wiring is not required.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention has a function of selecting and specifying a power window to be opened / closed according to a slide position of a knob unit having a knob, switching the presence / absence of a voltage to be applied to a motor by operating the knob, and raising / lowering the application direction. By providing a function to perform drive control, the power window open / close control can be operated by operating one knob without changing the position of the hand. Therefore, at least the number of power windows is required for the slide position taken by this knob unit. Select and deselect all other windows, select two previous or next windows, select two right or left windows, and add other appropriate combinations of positions. May be. The knob has three switching positions so that each motor is connected to a forward voltage applied to the motor, connected to a zero voltage at an intermediate position, and further connected to a voltage applied in the opposite direction.
[0007]
FIG. 1 shows a power window control operation unit of the present invention. A is a plan view and B is a side view. Reference numeral 1 denotes a panel having an H-shaped hole 11 in which a knob unit 2 is fitted and can slide in an H-shape. The knob unit 2 has a knob 23 on the upper surface side of the panel 1. The lift switch 22 and the base 21 are integrally formed with a short-circuit member 24 on the lower side of the panel 1 so as to selectively short-circuit a plurality of paired terminals disposed in the lower region of the panel 1 corresponding to the positions. Select the window position. The up / down switch unit 22 is supplied with a positive voltage and a ground voltage from a battery serving as a power source, and is applied to the window motor specified by the previous position selection corresponding to the three positions taken by the knob 23.

In addition, although the H-shaped slide position that is easy to take a position corresponding to the most popular front, rear, left, and right four-door power windows in a passenger car is presented here, not limited to this, appropriate position forms corresponding to all windows are shown. Can be adopted.
[0008]
[Example 1]
An embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a side view showing a section of the knob unit in section, and FIG. 3 is a circuit diagram of this embodiment. The knob unit 2 of this embodiment has a two-layer structure as can be seen from FIG. 2, and the one layer portion located above the panel 1 is a lift switch portion 22 on the base 21 and its knob 23. A lead wire 3 to which the potential of the positive electrode of the battery is supplied from the lower side of the panel 1 through the H-shaped hole 11 of the panel 1 and a lead to which the potential of the negative electrode (earth potential) is supplied The wires 4 are connected to each other by wiring, and these lead wires are flexible wires having a length so that the knob unit 2 can slide to any position. As shown in FIG. 3, terminals a and d to which the potential of the positive electrode of the battery is supplied via the lead wire 3, and a terminal b to which the ground potential is supplied via the lead wire 4, as shown in FIG. 3. And c and terminals e and f connected to the relay line are arranged. When the lift switch 22 does not touch the knob 23, the terminal f is in the normally closed relationship with the terminal c and the terminal e is normally closed with the terminal b as shown in the solid line, and when the knob 23 is operated to the down (DOWN) side, the broken line The terminal f opens the terminal c and is connected to the terminal d as shown by the above, and when the knob 23 is operated to the ascending (UP) side, the terminal e opens the terminal b as shown by the broken line. Operates to connect with a. When the hand is released from the knob 23, the terminal f returns to the terminal c, and the terminal e returns to the original normally closed state of the terminal b and the solid line.
[0009]
As shown in FIG. 2, the knob unit 2 has a structure in which two layers are disposed below the panel 1, and the second layer is a front / rear / left / right position selection mechanism including a short-circuit member 24. . This short-circuit member 24 is urged downward by a spring, and is electrically connected to each of the terminals which are positioned below each of the terminals and are separated into one in the central neutral position and four in the H-shape in the front-rear and left-right directions. The connection is designed to be stable and solid. Incidentally, when the knob unit 2 is shifted to the front left side, the short-circuit member 24 short-circuits the counter terminal composed of the central terminal g1 and the lower terminal h1 of the motor FL on the left side of the front seat. Next, when the knob unit 2 is shifted to the front right side, the short-circuit member 24 short-circuits the counter terminal composed of the center terminal g2 and the lower terminal h2 of the front seat right motor FR. Similarly, when the knob unit 2 is shifted to the rear left side, the pair terminal consisting of the terminal g3 and the terminal h3 is short-circuited, and when the knob unit 2 is shifted to the rear right side, the terminal g4 and the terminal h4 are The other pair terminals are short-circuited and all other pair terminals are opened. When the knob unit 2 is at the H-shaped center neutral position g, the short-circuit member 24 is on the center terminal g and opens all the counter terminals of the center terminal.
[0010]
Next, the operation when the knob unit 2 is placed at the front left position in this embodiment will be verified by the circuit diagram of FIG. As is apparent from this figure, one terminal f of the lift switch mechanism SW is connected to the upper terminals of the motors of the left and right doors FL and FR of the front seat via the relay line, and to the left and right doors RL and RR of the rear seat. Always connected to the lower terminal of the motor. The other terminal e is always connected to a central terminal g having four H-shaped tip terminals g1, g2, g3, g4. Now, since the knob unit 2 is placed at the front left position, the center terminal g is short-circuited by a short-circuit member 24 at the counter terminal composed of the terminal g1 and the terminal h1. In this state, when the knob 23 of the lift switch mechanism SW is operated to the down (DOWN) side in the figure, the terminal f opens the normally closed terminal c and switches to the terminal d. Therefore, the potential of the positive electrode of the battery is transferred from the terminal d to the terminal f, and the positive potential is applied to all the motors via the relay line from the upper terminal of the front seat left and right door motor to the lower terminal of the rear seat left and right door motor. Supplied. However, current does not flow because the paired terminals of the central terminals g2, g3, g4, which are always placed at the ground potential, and the motor terminals h2, h3, h4 of the right and left doors of the front seat are open. Only the circuit of the left door motor FLM in the front seat becomes a closed loop, current flows from the upper side to the lower side of the motor FLM, and the motor is rotated forward to open the window. On the contrary, when the lift switch mechanism SW is operated to the ascending (UP) side in the figure, the terminal f is connected to the normally closed terminal c, but the terminal e opens the normally closed terminal b and switches to the terminal a. Therefore, contrary to the previous case, a positive potential is supplied to the terminal e and a ground potential is supplied to the terminal f. The potential of the positive electrode of the battery is supplied from the terminal a to the terminal e and further to the central terminal g, that is, all the tip terminals g1, g2, g3, and g4 through the relay line. However, since all the terminals other than the motor FLM of the door on the left side of the front seat are open, the motor other than this motor is not driven, and the upper terminal of the motor FLM is grounded via the terminal f and is closed. A circuit is formed, this time current flows from the lower terminal to the upper terminal, reverses the motor and closes the window. The same operation is performed when the knob unit 2 is shifted to another position. However, when the rear seat window is selected, the window is when current flows from the lower terminal of the motor to the upper terminal in the figure. Is the forward rotation that opens, and when the current flows from the upper terminal toward the lower terminal, the rotation is the reverse that closes the window. As described above, in this embodiment, the power window to be driven can be specified corresponding to the position in the H-shaped hole 11 of the panel 1 of the knob unit 2, and when the knob 23 of the knob unit 2 is operated to the down (DOWN) side, it corresponds. When the window glass is lowered and opened, and the knob 23 is operated to the up (UP) side, the window glass is raised and the window is closed.
[0011]
[Example 2]
Next, FIG. 4 shows an example using a mechanism that can supply drive power from a battery to the lift switch mechanism without using flexible lead wiring when sliding the knob unit to the selected position of each window. A is a plan view showing the configuration of the operation unit main body under the panel, B is a diagram showing the knob unit, and the lower part shows a side view of the knob unit, and the middle part shows the up / down switch part. The upper left is a side view of the up / down switch unit, and the right is a bottom view of the up / down switch unit viewed from below. In this embodiment, the short circuit member for selecting the front / rear position and the left / right position is separately provided in the previous example, but only one short member 24 is used to select the windows of the four doors RR, RL, FR, FL. Like to do. On the peripheral wall surface of the lifting switch section 22 of the knob unit 2, two metal conductive bands 25 and 26 at different positions in the vertical direction, and a and b (c, d) serving as power input terminals of the lifting switch section 22. It is arranged in a form extending downward. When the knob unit 2 is slid to the selected position of each window along the H-shaped guide hole 11 formed in the panel 1, the power terminals a and b (or c and d) are installed on the operation unit main body side. The power supply terminals g and h connected to the positive and negative electrodes of the battery are in contact with each other, and the conductive bands 25 and 26 are in contact with terminals j and i installed on the operation unit main body side. The terminals g, h, i, j are respectively arranged at the selection positions (RR, RL, FR, FL) of the respective windows. The terminal j follows the top, the terminal i, and the terminals g, h Located at the bottom. In FIG. 4A, the positions of the power supply terminals g and h are shown shifted to the left side. However, this is a simplified drawing and is actually positioned above each selection terminal connected to the motor. is doing. The switch mechanism of the elevation switch unit 22 used here is in a neutral position when the knob 23 is not operated as in the previous example, the terminal e is in a normally closed relationship with the terminal b and the terminal f, and When the knob 23 is operated to the down (DOWN) side, the terminal e opens the normally closed terminal b and switches to the terminal a. When the knob 23 is operated to the ascending (UP) side, the terminal f is the normally closed terminal. The operation of opening d and switching to the terminal c is performed.
[0012]
Next, in this embodiment, the operation when the knob unit 2 is placed at the front left window selection position will be verified by the circuit diagram of FIG. Since the position is front left, the short-circuit member 24 short-circuits the opposite terminal of the window selection FL, and the power supply input terminal a of the elevating switch unit 22 is connected to the positive electrode of the battery and the power supply input terminal b is the battery. The conductive band 25 is in contact with the terminal j and the conductive band 26 is in contact with the terminal i. The connection relationship other than the window selection terminal at this time is the same at any window selection position except that the power input terminal is a, b or c, d. The circuit of the unit 22 is shown in common without corresponding to the window selection position. The upper conductive band 25 of the lift switch 22 is connected to the upper left j terminal in the figure, and the lower conductive band 26 is also connected to the upper left i terminal in the figure. In this state, when the knob 23 is tilted to the DOWN side, the terminal e opens the normally closed terminal b and switches to the terminal a, and the terminal f is short-circuited with the normally closed terminal d. And then supplied to the conductive band 25. Since this conductive band 25 is connected to the j terminal at the upper left in the figure, a positive potential is supplied to the counter electrode for selecting each position via a relay line, but the short-circuit member 24 short-circuits only the counter terminal at the FL position. Therefore, the positive potential of the power source is supplied to the lower end of the motor FLM on the left front door. On the other hand, the upper end of the motor is connected to the terminal i, and the terminal i is in contact with the lower conductive band 26 of the elevation switch section 22 as described above. Therefore, the negative electrode (ground potential) of the power source is connected via the terminals f and d. ). That is, in this state, a current flows from the lower terminal of the motor FLM on the left front door to the upper terminal side, and the window glass of the window is lowered to open the window. When the hand of the knob 23 is released, the state becomes neutral and the up / down switch returns to the normally closed state indicated by the solid line, so that the supply of power is cut off and the drive is stopped. When the knob is tilted to the UP side, the terminal e remains connected to the normally closed terminal b, and the terminal f opens the normally closed terminal d and is short-circuited with the terminal c. It is supplied to the conductive band 26 via f. Since the conductive band 26 is connected to the terminal i, a positive potential is supplied to the upper terminal of the motor FLM of the door on the left front side. The lower terminal of the motor is connected to the e terminal of the lift switch 22 via the short-circuit member 24, the terminal j, and the conductive band 25, and reaches the negative electrode of the power source. Accordingly, a current flows from the upper end to the lower end of the motor FLM, and the motor FLM is driven in the direction opposite to the previous rotation, and the window glass is raised and closed.
[0013]
Even when the knob unit 2 is located at another window selection position, the contact position between the terminal to be short-circuited and each terminal is different, and there is no difference in the raising and lowering operation of the window. In this embodiment, the knob unit slides in an H shape to change the position for selecting a window, but at each position, between the terminal fixed on the operation unit main body side and the conductive band or power input terminal provided on the lift switch unit 22. Since it is configured to be connected, it is not necessary to wire a flexible lead wire with a space to supply the power supply voltage to the up-and-down switch unit 22, and it is possible to reduce consumable members and useless space. Has a unique effect.
