Description

[Detailed description of the invention]

[Technical Field] The present invention provides tilt opening/closing and sliding opening/closing of transparent plates, opaque plates, panels, etc. (hereinafter referred to as opening covering materials or panels) for closing openings such as windows, doorways, ridge openings, etc. The present invention relates to a driving automatic opening/closing device, and in particular, but not exclusively, to an automatic opening/closing device for a sunroof of a motor vehicle. [Prior Art] For example, a sunroof of an automobile is equipped with an automatic opening/closing device that tilts and/or slides the sunroof (roof panel) open/close in response to a driver's switch operation. In Japanese Utility Model Application No. 58-148175, the forward/reverse energization switch of the motor that drives the sunroof to open and close is a manual switch, and a switch is provided to detect the sunroof a little before it is closed, and this switch is equipped with a toggle switch. By connecting the coil of a type of relay and inserting this series circuit into the motor energizing circuit, the switch stops energizing the motor slightly before the sunroof is closed, and then it starts again in response to the opening and closing of the manual switch. A sunroof drive circuit is proposed that fully closes the sunroof by resuming energization of the motor. However, this type of electric circuit, which energizes the motor for opening and closing the sunroof via a manual switch, has a relatively simple circuit configuration, but it requires precision, such as detecting mechanical overload and automatically stopping the overload response. Moreover, it is difficult to realize advanced automatic control.
In addition, manual switches, relay switches, and detection switches are all inserted into the motor energizing loop, so they must be of high capacity to withstand the motor energizing current and robust enough to ensure electrical opening and closing. It won't happen. While the manual switch is closed to the open drive or close drive side, if the contact of the switch contacts is not perfect, electric sparks will occur, the motor current will become unstable, and the switch contacts will wear out. However, when the motor is energized through a manual switch, the contact of the switch contacts depends on the pressing force of the fingers, so the motor current tends to become unstable and the switch contacts tend to wear out. Since fluctuations in motor current disturb the precise and highly automatic control described above, energizing the motor via a manual switch is virtually impossible for this automatic control. Conventional vehicle sunroof drive control devices that automatically stop in response to overload detect the motor load using a motor temperature detection resistor, compare this with an overload reference value, and automatically stop the motor in the event of an overload. do.
In a mechanism with a constant load, such a safety stop can be accomplished relatively easily. However, with the above-mentioned sunroof mechanism, when the sunroof is opened, the load is large until the front end of the slide panel leaves the weather strip, and then it decreases.When the sunroof is closed, the load is increased by raising the ring to lift the rear end of the slide panel. The load suddenly increases after the front end of the slide panel contacts the weather strip, and if a deflector arm is provided, the load increases when the deflector arm is pressed down, causing the load to increase significantly even during normal operation. fluctuate. To prevent malfunctions even under such load fluctuations,
In the invention disclosed in Japanese Patent Publication No. 2-06648 (Japanese Patent Application Laid-open No. 58-222729), the entire operation stroke of the slide panel is divided in accordance with load changes, an overload reference value is set for each, and the electric drive mechanism is A signal generating means that generates an electric signal in conjunction with each other is combined to obtain a signal corresponding to the position of the slide panel, and the overload reference value is changed based on this signal and compared with the actual motor load. ing. According to this, the overload reference value can be selected in accordance with the load of the entire stroke of the slide panel, so that malfunction does not occur even with the above-mentioned load fluctuations. Such panel drive control requires complex control functions and is therefore performed by a computer system centered on a CPU. The switch for inputting the operator's instructions, that is, the input switch, is a weak current energized switch for input only.
A circuit for energizing the motor, that is, a motor driver, is equipped with a switching relay for forward and reverse energization, and a switching circuit for energizing the relay coil. In response to input switch operation, the computer system turns on/off the motor driver's switching circuit.
By applying an off signal and energizing/de-energizing the relay coil of the switching circuit corresponding to this, the forward and reverse energizing circuits of the motor driver are selectively closed or opened. Among this type of sunroof opening/closing devices, those that perform tilt opening/closing and sliding opening/closing are provided with two or more sets of input switches, one for instructing tilt opening/closing and the other for instructing slide opening/closing. [Problem to be Solved by the Invention] However, the tilt/slide opening/closing mechanism slides and closes the sunroof by moving the sunroof back from the fully open position, and then tilts it up. It is a mechanism that tilts down to close and then slides to open, that is, when the panel is moved forward from the fully closed position, it slides open, and when it is moved back from the fully closed position, it is tilted open, so when the panel is in the slide opening/closing section, the tilt switch Even if you operate the slide switch, the computer does not respond, so the tilt will not operate, and even if you operate the slide switch, the slide will not operate when it is in the tilt opening/closing range. Even if it is activated, the current tilt or slide must be executed first, so for example, to open the tilt when the panel is in the slide opening/closing section, operate the slide opening/closing instruction switch and slide it. It is troublesome to select and operate the input switch, such as fully closing the switch and then operating the tilt open/close instruction switch to open the tilt. Further, it is preferable to reduce the number of switches from the viewpoint of saving space inside the vehicle and saving resources. The present invention is an opening/closing device for an opening covering material that performs tilt opening/closing and sliding opening/closing, which can realize precise and advanced automatic control, by reducing the number of opening/closing instruction input switches and making it easier for the user to select and operate the switches. Aim to be simple. [Technical Means for Solving the Problems] The automatic opening/closing device for an opening covering material of the present invention is connected to the opening covering material 23, and when the opening covering material 23 is moved back (forward movement) from the fully open position (fully opened). Opening covering material 2
3 to close (fully closed), then tilt up, and by moving the opening covering 23 forward (backwards) from the tilt-up completion position, tilt down the opening covering 23 to close (fully closed), then slide to open. An opening/closing mechanism including a reciprocating member 41, and an electric drive mechanism including an electric motor 11 and driving the reciprocating member 41 forward and backward in response to forward and reverse rotation of the electric motor 11; a given forward and reverse instruction signal; and a motor driver 230, 250 that energizes and stops the electric motor 11 in the forward and reverse directions in response to a stop instruction signal; a tilt opening/closing section (,) and a sliding opening/closing section (, =

When electric signals A and B representing the opening/closing section (, = A+B+C) are being generated, the motor is turned on or off within the slide opening/closing section in response to the first signal (SWN ON) and second signal (SWR ON). , a slide opening/closing control means 11 which gives a reverse direction instruction signal to the motor driver and gives a motor stop instruction signal to the motor driver when the slide is out of the slide opening/closing section;
0; Note that the symbols inside the brackets are attached to corresponding elements in the embodiments shown in the drawings and described later. [Operation] Electrical signals A and B generated by the signal generating means 300
With reference to FIG. decipher. That is, when the signal generating means 300 is generating electric signals A and B indicating the tilt opening/closing section (,), the tilt opening/closing control means 110 correspondingly changes the input means (SWN/SWR changeover switch) In response to the first signal (SWN ON) and the second signal (SWR ON), a forward and reverse instruction signal for the motor within the tilt opening/closing section is given to the motor driver, and a motor stop instruction signal is sent to the motor when the motor is out of the tilt opening/closing section. Give to the driver. Motor drivers 230 and 250 respond to these signals to energize and stop electric motor 11 in forward and reverse directions. This enables tilt opening and closing. Further, when the signal generating means 300 is generating electric signals A and B representing the slide opening/closing section (,=A+B+C), the slide opening/closing control means 110 correspondingly controls the input means (SWN/SWR changeover switch). The first signal (SWN
In response to the second signal (SWR ON) and the second signal (SWR ON), a forward and reverse direction instruction signal for the motor within the slide opening/closing section is given to the motor driver, and a motor stop instruction signal is given to the motor driver when the motor is out of the slide opening/closing section. Motor driver 230, 250
In response to these signals, the electric motor 11 is energized in forward and reverse directions and stopped. This allows the slide to open and close. In this way, the inputs of one set of input means (SWN/SWR changeover switch), that is, the first signal (SWN ON) and the second signal (SWR ON), are generated by the electric signals A and B generated by the signal generation means 300. It is determined whether the instruction is tilt open/close or slide open/close. The operator (driver) can determine whether the opening covering material 23 is in the tilt opening/closing section or in the sliding opening/closing section by looking at the state of the opening covering material 23, and if provided with an indicator, see the indicator. This allows easy recognition, and the input means (SWN/SWR changeover switch) is operated based on this recognition. Therefore, the signal generating means 3
00 is the electric signal A, B indicating whether the opening covering material 23 is in the tilt opening/closing section or in the sliding opening/closing section.
is given to the tilt opening/closing control means 110 and the slide opening/closing control means 110, so the recognition by the operator and the recognition by the control means 110 are the same. /SWR selector switch) input, that is, the first signal (SWN on)
and the response to the second signal (SWR on) is:
Perfectly matches the operator's intent. In other words, the operator can issue tilt open/close instructions and slide open/close instructions in accordance with the state of the opening covering material 23 at that time by operating only one set of input means (SWN/SWR changeover switch). , the operator's burden on switch selection and operation is reduced, the switch equipment space is reduced, and the number of switches is reduced. In the sunroof opening/closing device disclosed in the above-mentioned Japanese Utility Model Publication No. 58-148175, in which the motor that opens and closes the sunroof is energized in both forward and reverse directions through a manual switch, the motor current tends to become unstable, and the switch contacts tend to wear out. However, in the automatic opening/closing device of the present invention, the fluctuation of the motor current disturbs precise and advanced automatic control, but in the automatic opening/closing device of the present invention, both the signal generating means 300 and the input means (SWN/SWR changeover switch), the tilt opening/closing control means 110 and the slide opening/closing control means 11
The electric motor 11 of the electric drive mechanism is provided with a separate motor driver 2.
30,250 is energized, and this motor driver 23
0.250 is an automatic operation that energizes and stops the electric motor 11 in the forward and reverse directions in response to the applied forward and reverse instruction signals and stop instruction signals, so that the electric current supplied to the motor is stable, precise, and accurate. It does not disturb highly automatic control and wear and tear on the switch contacts in the motor driver is low. The preferred embodiment of the present invention further includes means 240, 260, 270 for detecting the load of the opening/closing mechanism, and reference value setting means 320 to 3 for setting an overload reference value.
60 and means 370 for detecting an overload by comparing the load of the opening/closing mechanism with a reference value, and the slide opening/closing control means 110 sends a motor stop instruction signal to the motor driver when an overload is detected during slide opening/closing operation. shall be given to the tilt opening/closing control means 1.
Reference numeral 10 provides a motor stop instruction signal to the motor driver when an overload is detected during tilt open/close drive. According to this, when the slide is energized to open, overload detection is used to stop the motor when the slide is fully opened, and when the tilt is energized to open, the overload detection is performed and the motor is stopped when it is assumed that the tilt-up is completed. There is no need for the signal generating means 300 to generate a slide open completion signal or a tilt up completion signal, and the opening degree detection process can be performed by a simple process using a relatively simple detector. Furthermore, when the opening covering material 23 slides closed and reaches a predetermined opening degree before fully closing, the opening covering material 23 temporarily stops and then starts the closing movement again. Therefore, if the opening is less than the predetermined opening, there is a risk that an obstacle will interfere with the closing slide.
In addition, by setting the opening degree to such a degree that even if such a situation occurs, it can be easily removed, it is possible to prevent anything that will obstruct the closing slide, and even if it is in a state that does not interfere with the closing slide,
Since you will be paying attention to that direction when you pause, you will be careful not to interfere with the closing slide after that, which will also prevent interference with the closing slide. In a preferred embodiment of the present invention, the signal generating means 300 is a disc which is connected to an electric drive mechanism, rotates in conjunction with the rotation of the electric motor 11, and has two stages of concave and convex portions on its circumferential surface for operating the switch. a first switch 200a which is disposed opposite to one of the concavities and convexities for switch operation and is driven to open and close by the concavities and convexities; , a second switch 200b that is driven to close, and the open and close signals of these switches indicate the open and close modes of four sections (-). The electric motor 11
A temporary stop instruction signal shall be given to the motor driver. According to this, since both slide opening/closing and tilting opening/closing are performed, there are roughly four states: slide open, slide closed, tilt closed, and tilt open.
The signal generating means 300 can be constructed compactly using a relatively thin switch operating cam. In the example described below, the four states are a state (mode) representing the section of the slide fully open/just before fully closed, a state (mode) representing the section immediately before fully closed/fully closed, and a state (mode) representing the section of the slide fully closed/completely closed. It is assigned to a state (mode) representing the section and a state (mode) representing the section of tilt-down completion/tilt-up completion. In addition, in the embodiment, since it is necessary to detect a predetermined opening degree before the slide is fully closed, the cam is provided with concavities and convexities in the mode section so that the switch generates a status signal that can be distinguished from the mode. Since this status signal is the same as any of the modes ~, the slide opening/closing control means 110 detects the switching of the status signal when the panel is closed, and detects the predetermined opening degree before fully closing. As a result, in addition to being able to control slide opening/closing, tilt opening/closing, and four modes using a thin switch operating cam with only two stages of concave and convex sections for switch operation, it is possible to control one more mode (slide opening/closing). It is now possible to temporarily stop at a predetermined opening degree when closing. Other objects and features of the present invention will become clear from the embodiments described below with reference to the drawings. [Embodiment] FIG. 1 shows an outline of an electric drive mechanism according to an embodiment of the present invention. In this embodiment, an opening 22 of a roof 21 of an automobile is used.
This is to drive and control the roof panel 23 that opens and closes. An opening 22 is formed in a roof 21 of an automobile, and this opening 22 is slid open/closed and tilted open/closed by a roof panel 23. Panel 23 is actuated by drive cables 24,25. The sunroof panel 23 is fixed to brackets placed on both sides of the opening 22 (only one side is shown in FIG. 1). As shown in FIG. 2, the front edge of the bracket 26 is provided with an elongated hole 27 that descends toward the front of the vehicle, and a pin 28a of the front guide 28 is engaged with this elongated hole 27a. A front shoe 29 is attached to the lower part of the front guide 28, and a front shoe 29 is attached to the bottom of the front guide 28.
One end of the front ring 30 is rotatably attached to the shaft 3.
The other end of the front ring 30 is pivotally connected to the bracket 26 at a shaft 32. As shown in FIG. 4, an engagement pin 38 is arranged on the rear edge side of the bracket 26, and a plate 33 is fixed with locking pins 34, 35. A guide slot 36 is formed in the plate 33, and the slot 36 has a horizontal portion provided on the front side of the vehicle and an inclined portion rising from the rear end of the horizontal portion toward the rear of the vehicle. Further, a tilt pin 37 is installed at the front end of the plate 33. The link 39 has a roller pin 40 at its front end and a rear shoe 41 at its rear end, and is rotatably connected to the link 39. The link 39 is formed in an arc shape centered on the front end of the guide rod 36 which can be engaged with the tilt pin 37 at its upper end. It has a notched groove 42 and a guide pin 43. The guide pin 43 is engaged and guided in the guide slot 36. The end portions of the drive cables 24, 25 are connected to the rear shoe 41, as shown in FIG. Therefore, the drive cables 24 and 25 move forward and backward through the rear shoe 41, the guide link 39, the guide pin 43 of the guide link 39, and the guide slot 36 in which the guide pin 43 is engaged, to the bracket 26 and further to the front. The signal is transmitted to the guide 28. As shown in FIGS. 4 and 5, the front shoe 29 and the rear shoe 41 are connected to the roof opening 2.
It is engaged and guided by guide rails 44 disposed on both sides of 2. Further, the foot portion 40a of the roller pin 40 is inserted into the rail groove 44a on the inside side of the vehicle interior of the guide rail 44.
is guided to engage. On the other hand, the rail groove 44 outside the vehicle of the guide rail 44
In b, a gap 38a of the engagement pin 38 is engaged and guided. Furthermore, as shown in FIGS. 4 and 6, a block 45 is fixedly disposed within the guide rail 44, and a head 40b of a roller pin 40 provided on the guide link 39 is guided on the interior side of the block 45. An inclined groove 47 for guiding the head 38b of the engaging pin 38 fixed to the bracket 26 is formed on the outside of the vehicle interior. Further, a notch is formed in the flange portions 48 and 49 of the guide rail 44 at the location where the block 45 is arranged. Therefore, as the guide link 39 moves forward, the engagement pin 38 and the roller pin 40 move into the inclined grooves 46 and 4, respectively.
7 and can be lifted up and removed from the rail groove 44b or 44a of the guide rail 44 one after another. Further, a rectangular opening 5 is provided at the upper end of the block 45.
Flanges 50 and 50b having 0a are formed (FIG. 4). A stopper 52 disposed on the other end side of a leaf spring 51 whose one end is fixed to the front guide 28 is engaged with this opening 50a when the panel 23 is closed and tilted open. As a result, movement of the front guide 28 toward the front of the vehicle is stopped. In addition, when the movable panel 23 is slid open,
The tip 51a of the leaf spring 51 is pressed by the lower end 26a of the bracket 26, and is slidable within the guide rail 44. Therefore, as the engaging pin 38 moves up the inclined groove 47 of the block 45, the lower end 26 of the bracket 26
The leaf spring 51, which had been pressed by the block 45, moves upward and engages with the opening 50a of the block 45 (see FIG. 4). Further, an arm 52 is arranged on the front guide 28, and a rain gutter 53 is connected to the rear end.
Therefore, the rain gutter 53 always slides together with the roof panel 23, and can completely catch raindrops from the rear edge of the panel 23 (see FIGS. 1, 4, and 7). To explain the operation of the mechanism described above, the panel 23 normally closes the opening 22 as shown in FIG. When the drive cable 25 is actuated to move the rear shoe 41 toward the rear of the vehicle (to the right in FIG. 5), the guide link 39 also moves backward. The guide pin 43 is engaged and guided from the horizontal part to the inclined part of the guide slot 36 of the plate 33, and
3, the panel 23 is pulled rearward via the bracket 26 and its rear edge is urged downward. Therefore, the engaging pin 38 fixed to the bracket 26 descends along the inclined groove 47 of the block 45, and the movable panel 23 descends while moving rearward (FIGS. 7 and 8). At this time, when fully closed, the pin 31 is slightly lower than the pin 32, as shown in FIGS. 2 and 5, but as it descends, the front link 30
is horizontal as shown in FIGS. 3 and 8, so that it can be accommodated in the rear lower part of the roof 21 of the automobile, and the opening 22 is opened by sliding the panel 23. On the other hand, when the rear shoe 41 is moved forward by driving the drive cable 25 from the position shown in FIG. The guide link 39 rotates and rises while moving forward (see FIG. 9). As a result, the notch groove 42 of the guide link 39 engages with the tilt pin 37 implanted in the plate 33. When the rear shoe 41 moves further forward, the guide link 39 rotates upward while moving forward, causing the rear edge of the panel 23 to rotate upward and stand up, opening the opening 22 (see FIG. 10). Moreover, all the operations of the panel 23 are performed by the bracket 2.
6, after the panel 23 is assembled to the roof 21 of the automobile, the bracket 2
6 is in the fully closed position shown in FIG. 5, the panel 23 is fitted into the opening 22 with its weather strip bent, and then assembled and fixed to the bracket 26. As mentioned above, the fully closed state (Fig. 5 and 11
View 45 from the rear of the vehicle (right side in the drawing)
When the panel 23 is slid downward, the panel 23 slides open (FIG. 11c), and then slides further to fully open (FIG. 11d). When the shoe 45 is driven toward the front of the vehicle (to the left in the drawing) from the fully slid state of the panel 23, the state shown in FIG. 11c changes to the state shown in FIG. 11b, where the panel 23 closes the opening 22, and A weather strip on its front edge closes the opening 22. When the shoe 45 is further driven forward of the vehicle (to the left in the drawing) from this fully closed state, the rear end of the panel 23 rises and is tilted open (FIGS. 9, 10, and 11a). That is, the tilt is fully open (Fig. 10 and 11a)
When the shoe 45 is driven toward the rear of the vehicle (to the right in the drawing), the panel 23 first tilts closed to completely close the opening 22 (fully closed: Fig. 11b), then slides open and then slides. Fully open (11th d
Figure). On the other hand, if the slide is fully open, the
When the vehicle is driven forward, the panel 23 is fully closed, and furthermore, the rear end of the panel 23 is erected and tilted fully open. In this way, by simply sliding the shoe 45 backward and forward, the panel 23
changes the state from tilt fully open - tilt partially open - fully closed - slide partially open - slide fully open, and vice versa, changes the state from slide fully open - slide partially open - fully closed - tilt partially open - tilt fully open. The cables 24 and 25 that drive each of the shoes 45 on the side of the vehicle are connected to a cable drive mechanism that mainly includes a reducer 9 and a motor 11. and 25 are driven forward and backward in opposite directions by the reducer 9 section. FIG. 12a shows a plan view of the cable drive mechanism, and FIG. 12b shows a sectional view. The reducer 9 includes a worm 14 ₁ fixed to the rotating shaft of the motor 11 and a worm wheel gear 1 that meshes with the worm 14 ₁ and is pivotally connected to the rotating shaft 15.
4 ₂ , a gear 14 ₃ coupled to the gear 14 ₂ via a friction clutch 16 ₂ including a disc spring 16 1 and fixed to the rotating shaft 15; a gear 14 ₅ meshing with the gear 14 ₃ and fixed to the rotating shaft ₁₈ ; , a gear 1 fixed to the rotating shaft 18 and meshing with the toothed cables 24 and 25;
0 etc. constitutes a gear train. At the tip of the rotating shaft 15, as shown in FIG. 13, there is an eccentric bearing 19 having an eccentric circumferential surface 19a.
The cam 2 is fitted onto the circumferential surface 19a.
0 is pivoted. A planetary gear 201 is pivotally mounted on the eccentric bearing 19. The planetary gear 201 meshes with the housing inner teeth 210, and a pin 202 is formed on the planetary gear 201. Further, a cam 20 is pivotally attached to the leading end of the rotating shaft 15. A through groove is formed in the cam 20, and a pin 202 is engaged with this groove. As a result, the bearing 19 rotates as the rotating shaft 15 rotates, and the planetary gear 201 rotates between the housing internal teeth 2.
10 and rotate differentially, the pin 202 moves, and the cam 20 is rotated by being pushed by this pin 202. On the circumferential surface of the cam 20, there is one groove 20b in the upper stage.
However, two grooves 20a and 20c are formed in the lower part, and a limit switch 200b and a limit switch 200a are arranged in the upper part and the lower part of the circumferential surface, respectively, facing each other. In this embodiment, the states of the panel 23 are roughly shown as a slide open state (mode), a slide closed state (mode) from just before the slide is fully closed to fully closed, and a tilted closed state (mode) from the completion of tilt down to fully closed. ,and,
Four states (tilt open state (mode)) are detected, and the panel opening/closing control mode is specified in each state. More specifically, there are two switches 200a and 200b for opening detection, and the combination of opening and closing of these switches roughly represents only four states. In addition, a groove 20c is formed, and the groove 20c allows the switch 200a to be opened with the panel 23 opening approximately 10 cm toward the slide open side from the fully closed position. The mode in which the switch 200a is opened at the groove 20c (temporary stop instruction state: mode B) is in the above-mentioned mode section. FIG. 14 shows the relationship between the rotation angle of the cam 20, the open and closed states of the limit switches 200a and 200b, and the panel opening/closing control operation mode. Among the modes, (B) is a temporary stop instruction mode. The cam 20 rotates counterclockwise in FIG. 14 by urging the electric motor 11 to rotate normally from the tilt-up completed state (the state shown at the leftmost end of FIG. 14: corresponds to FIG. 11a), and the panel 23 is tilt down complete, fully closed, position just before fully closed, fully closed 10
cm, and as the limit switches 200a and 2 are fully opened, as shown in FIG.
00b is opened and closed. The cam 20 is rotated clockwise in FIG. 14 by reversely energizing the electric motor 11 from the fully open state (the state shown at the rightmost end of FIG. 14: corresponds to FIG. 11d), and the panel 23 is fully closed by 10 cm. As shown in FIG. 14, the limit switch 200 is moved to the forward, fully closed position, fully closed, tilt down completed, and tilt up completed.
a and 200b are opened and closed. This example detects overload (particularly when a human body is caught) and stops the motor in the event of an overload.
The temporary stop before cm for safety is when the panel 23 is in the mode and when the panel 23 is slid from the fully open side to the fully closed side. Referring again to FIGS. 12a and 12b.
When the cable 24 or 25 is stopped and restrained by a force exceeding a certain level, the friction clutch 16 ₂ slips and the gear 14 ₂ is rotationally driven by the motor 11, but the shaft 15 and the gear 14 fixed to the shaft are
₃ does not rotate. That is, the clutch ₁₆₂ is provided as a mechanical safety mechanism. FIG. 15 shows an electric circuit that performs forward and reverse drive energization and energization control of the motor 11. Referring to FIG. 15, one end of the motor 11 is connected to the power supply voltage +12V or the shear sea earth via the relay contact 231 of the motor driver 230.
The other end is connected to the power supply voltage +12V or to the sea-sea ground via a load detection resistor 240 and a relay contact piece 232. Relay contact 2 that makes this connection
31 and 232 are relay coils 23, respectively.
3 and 234. In this embodiment, a resistor 240 is used as a means for detecting the load. Further, the relay coils 233 and 234 are connected to the drive transistor 25 of the relay drive circuit 250, respectively.
1 and 252. This relay drive circuit 250 includes an electric control device 100, which will be described later.
Output ports ₀₀ and ₀₇ of the microprocessor 110 are connected. When the transistor 251 is turned on, the relay coil 233 is energized and the relay contact piece 231 switches to the shear/shear earth side, and the power supply voltage +12V-

Give Vcc. The filter circuit 260 is a filter that removes high frequency fluctuations (high frequency components) of the motor load detection voltage (voltage of the resistor 240).
Diodes 261 and 262 are provided to protect the subsequent operational amplifier by cutting an input voltage higher than Vcc to Vc+Vr (Vr is the forward voltage drop of the diode) and cutting an input voltage lower than ground potential to -Vr. Amplification circuit 270 amplifies the output of filter circuit 260 to a required level. This amplifier circuit 27
The output Vs of 0 will be treated as the load detection voltage from now on. The addition circuit 320 adds a voltage at an allowable value level to the load detection voltage. The additional voltage is adjusted and set by a variable resistor 324. Delay circuit 330 provides a delay to the addition output.
In order to reduce the sensitivity difference between the rise and fall of the addition output, a diode 333 is connected to the capacitor 332 so that a delay is applied only at the rise and no delay is applied at the fall.
In order to correct the forward voltage drop of 3, the diode 333 is idealized in the operational amplifier 331. The memory circuit 340 has a load detection voltage Vs and a constant voltage.
The difference Vcc-Vs from Vcc is divided by resistors 345 and 346 and applied to a storage capacitor 341. When the panel 23 is closed, the transistor 343 is turned off for a predetermined time ts from the start of the closing drive, the transistor 342 is turned on, and the capacitor 3

A voltage obtained by dividing Vs is held in the capacitor 341. In this embodiment, the full opening of the slide and the completion of the tilt-up are detected when the load current of the motor 11 increases excessively, and the detection reference value at this time is set by the resistors 351 and 352 and the transistor 350. That's what I do. When the mode is open direction drive (motor forward rotation bias),
During tilt-up drive (motor reverse energization) in mode and mode, transistor 350 is turned off, and resistor 3

The voltage at the anode of the diode 362 (the lower of the storage voltage and the delay voltage) is the overload reference voltage Vmd, and is applied to the comparator 370 at the subsequent stage. The comparator 370 compares the output of the delay detection level check circuit 360, that is, the overload reference voltage Vmd, and the detected load voltage Vs, so that the latter Vs is higher than the former Vmd.
The microprocessor 1 sends a low-level "0" signal that indicates normality when the latter Vs is lower than Vmd, and a high-level "1" signal that indicates an abnormality when the latter Vs is higher than the former Vmd.

A motor reverse rotation instruction switch SWR and a motor forward rotation instruction switch SWN are connected to ₂₃ as means for instructing opening and closing of the panel 23. These switches remain closed only as long as they are pressed down.
When the button is released, it returns to the open position. The open/close reading of these switches by the microprocessor 110 is determined by the above-mentioned mode, and depending on the mode and which switch is closed, it can be read as tilt open, close drive, slide open, or close drive. To,
The driving of the panel 23 is determined. When the switch SWR is closed, the motor continues to be energized in reverse until the conditions shown in Table 1 below are met, and the switch is closed.
When SWN is closed, the motor continues to be energized for normal rotation until the conditions shown in Table 1 are satisfied.

[Table] Figure 14 shows the mode sections. In FIG. 14, modes are tilt opening/closing sections, and modes are sliding opening/closing sections. In order to clarify which side of the mode the panel 23 has stopped on (tilt opening/closing section side or slide opening/closing section side) due to the motor stopping at fully closed (contact point with mode), an open/close instruction switch is set. As shown in FIG. 15, four light emitting diodes L1 to L4 are arranged near SWR and SWN, and are connected to the microprocessor 110. Under the lighting control of the microprocessor 110, L1 L2 is lit when the opening/closing side is not fully closed, L2 is lit when the slide opening/closing side is fully closed, L3 is lit when the tilt opening/closing side is fully closed, and L4 is lit when the tilt opening/closing side is not fully closed. The lights are turned off. These light emitting diodes L1 to L4

The relationship between the meaning of the closure and the content is shown in Table 2 below.

〔Effect of the invention〕

As described above, according to the present invention, the operator only needs to operate one set of input means (SWN/SWR changeover switch) to issue tilt open/close instructions and slide open/close instructions according to the state of the opening covering material 23 at that time. This reduces the burden on the operator in selecting and operating switches, requires less space for installing switches, and requires fewer switches. In the sunroof opening/closing device disclosed in the above-mentioned Japanese Utility Model Publication No. 58-148175, in which the motor for opening and closing the sunroof is energized in the forward and reverse directions through a manual switch, the motor current tends to become unstable and the switch contacts tend to wear out. However, in the automatic opening/closing device of the present invention, the fluctuation of the motor current disturbs precise and advanced automatic control, but in the automatic opening/closing device of the present invention, both the signal generating means 300 and the input means (SWN/SWR changeover switch), the tilt opening/closing control means 110 and the slide opening/closing control means 11
The electric motor 11 of the electric drive mechanism is provided with a separate motor driver 2.
30,250 is energized, and this motor driver 23
0.250 is an automatic operation that energizes and stops the electric motor 11 in the forward and reverse directions in response to the applied forward and reverse instruction signals and stop instruction signals, so that the electric current supplied to the motor is stable, precise, and accurate. It does not disturb highly automatic control and wear and tear on the switch contacts in the motor driver is low.
