Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a drive device for a rectifying plate for an automobile that controls a rectifying plate such as a rear spoiler to a predetermined operating attitude.

[Conventional technology]

In general, it is used to stabilize the maneuverability by rectifying the wind during high-speed driving and adjusting the air resistance and lift generated on the vehicle body, and to improve high-speed driving performance by improving the contact between the tires and the ground. However, there is an air spoiler.

For example, the air spoiler is disclosed in Japanese Patent Application Laid-Open No. 60-92993.
As seen in the above publication, it is attached to the vehicle body and is controlled to be switched between an upright operating position and a laid down non-operating position by a drive device.

[Problem that the invention attempts to solve]

As described above, the attitude of the air spoiler is controlled by the drive device, and the baffle plate may be attached to an opening/closing body such as an openable trunk lid or a hatchback type back door.

In such embodiments, there are cases where the opening/closing body is opened and closed with the rectifying plate in an upright position. There is a risk that the plates will collide and be damaged. In particular, in the case of a hatchback type back door, the possibility of collision with a beam or the like increases as the opening/closing operation of the opening/closing body is large.

Therefore, this invention was developed to create a rectifier plate for automobiles that is designed to prevent collisions with ceilings of garages, etc. when the rectifier plate is in the operating position and the opening/closing body is opened. The purpose is to provide a drive device for

[Means to solve the problem]

In order to achieve the above object, this invention allows the rectifying plate provided on the openable/closable body to be placed in an operating position in which it stands up from the body by the forward or reverse rotational power of the drive motor, and in a rectifying position in which it is in a reclined position. In the drive device that controls switching between the operating position and the operating position, the drive motor is controlled to rotate in one of the forward and reverse directions when the switch operation of the operation switch and the closing signal from the detection means that detects the opening and closing of the opening/closing body are brought into contact. A first control unit that can disconnect and connect the rectifying plate in an operating position, and a disconnecting and connecting unit that controls the drive motor to rotate in the other direction by operating an operation switch, and disconnects and connects the rectifying plate in an inactive position. and a second control unit that is capable of operating, and the second control unit is brought into contact by a door opening signal from a detection means that detects opening of the opening/closing body when the current plate is in the operating position. do.

[Effect]

According to such a current plate driving device, when the opening/closing body is closed, the current plate can obtain an operating posture in which it stands up from the opening/closing body and a non-operating posture in which it lies down due to the forward rotation or reverse rotation power from the drive motor. . next,
When the opening/closing body is opened while the current plate is in the operating position, the second control unit is brought into contact with the detection signal from the detection means that detects the opening of the opening/closing body, and the current plate is placed in the non-operating position. This will prevent the current plate from colliding with the garage ceiling, beams, etc.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 10.

In the figure, numeral 1 indicates a rectifying plate such as a rear spoiler, which is provided on the upper surface of the back door 3 which can be opened and closed.

The back door 3 has a locking device as shown in Figure 2.
Opening and closing is possible by locking and unlocking RK, and when the locking device RK is connected to the switch S of the opening/closing body operation section 5, the actuator AC is activated and the lock is released.

The current plate 1 is formed along the width direction of the vehicle, and is swingably attached to the back door 3 via hinge members (not shown) fixed to the back door 3 at both ends. Further, a substantially central portion of the current plate 1 is attached to a mounting portion 9 of a bracket 7 with screws 10 or the like.

The bracket 7 consists of a mounting part 9 to which the rectifying plate 1 is attached, and arm parts 15, 15 extending from both sides of the mounting part 9 and interlockingly connected with a slider 13 of an actuation mechanism 11, which will be described later. At the upper end of the arm portion 15, the bracket 7 is rotatably supported by pivot shafts 18, 18 on flanges 28, 28, which are erected on both sides of a base plate 27 attached to the back door 3.

The operating mechanism 11 is long in the longitudinal direction of the vehicle body, and is housed in a drive case 17 fixed to the base plate 27, and is a drive mechanism that can be rotated in forward and reverse directions by an operation switch ST provided near the driver's seat. Motor 19 and output shaft 21 of drive motor 19
The rotating shaft 25 is integrally connected to the rotating shaft 25 by a set pin 23, and the slider 13 is screwed onto a threaded portion 25a of the rotating shaft 25.

The rotating shaft 25 is arranged substantially horizontally along the output axis W of the drive motor 19, and both front and rear ends are supported by bearings 29, 2 provided on the base plate 27.
It is rotatably supported by 9.

The slider 13 is provided with a mounting portion 35 protruding downward from the opening 33 of the base plate 27 at the lower part of the main body portion 31 in which a female threaded portion is formed to engage with the threaded portion 25a of the rotating shaft 25. Mounting part 3
5 comes to reciprocate (in the left-right direction in FIG. 1) by rotating the rotating shaft 25 in the normal or reverse direction. At this time, the reciprocating range is determined by stoppers 3 provided at both front and rear ends of the opening 33 extending from the base plate 27.

That is, when the slider 13 comes into contact with the stopper 37 at the front (on the left side in FIG. 1), the slider 13 reaches the maximum backward movement position, and when it comes into contact with the stopper 37 at the rear (on the right side in the same figure), it reaches the maximum forward movement position. becomes.

On the other hand, the slider 13 protruding from the opening 33
The mounting portion 35 is interlocked with the arm portion 15 of the bracket 7 by a pin 39 via an elongated hole 41 having an allowance for play.

The play area of the elongated hole 41 is divided into an operating position B (dashed line in FIG. 4) in which the mounting portion 9 of the bracket 7 stands up with the pivot shaft 18 as a fulcrum when the slider 13 reciprocates, and a non-operating position A in which it lies down. (solid line in the same figure), but at that time, the pin 39 is set to a size that allows it to move easily, so that no load is applied to the pin 39.

The upper part of the slider 13 has first cam surfaces 43a on both sides.
A cam body 43 having a second cam surface 43b is provided, and the first cam surface 43a is used for the backward movement of the slider 13 and the third cam surface 43b.
When moving to the left in the figure, it comes into contact with the switch terminal 45a of the first switch 45. Also, the second cam surface 43b
The first and second switches 45 and 46 are activated by contacting the switch terminal 46a of the second switch 46 when the slider 13 moves forward, moving to the right in FIG.
The motor circuit ML of the drive motor 19 is controlled to be "off" by signals from the switches 45 and 46. This causes the drive motor 19 to stop.

A mounting bracket 49 extends from the base plate 27 and is fixed to the upper surface of the back door 3 with bolts 51.

FIG. 2 shows a control circuit for the drive motor 19. The drive motor 19 is the first and second relay switch.
The switch terminals RC ₁ and RC 2 of RS-1 and RS- ₂ switch from the first contact P ₁ to the second contact P ₂ to rotate forward or reverse.

That is, the first and second relay switches RS-1, RS
-2 switch terminals RC ₁ and RC ₂ are relay coils
By excitation of LC-1 and LC-2, the first contact _P1 is switched to the second contact _P2 , and the first contact is normally
Connected to contact _P1 . The second contact _P2 is connected to the positive side of the battery power source BAT, and the first contact _P1 is connected to the negative side of the battery power source BAT.

Relay coil LC of first relay switch RS-1
One end of -1 is grounded via the first switch 45. The other end is a PNP type transistor T
Connected to collector No. 1. Transistor T1
The emitsuta is a battery power supply BAT, and the base is
Connected to the output side terminals of the AND circuit 53, respectively,
When a high level "1" signal is input to the base from the AND circuit 53, it turns on and the collector current flows to the relay coil LC-1, causing the relay coil LC
-1, the excitation state is ensured.

Relay coil SC of second relay switch RS-2
One end of -2 is grounded via the second switch 46. The other end is a PNP transistor T2
is connected to the collector. The emitter of transistor T2 is the battery power supply BAT, and the base is OR
They are connected to the output side terminals of the circuit 55, and when a high level "1" signal is input to the base from the OR circuit 55, it is turned on, and the collector current flows to the relay coil LC-2, which is excited. The state will be ensured. Further, the first and second switches 45 and 46 connected to the relay coils LC-1 and LC-2 are turned off and on when the current plate 1 is in the operating position B or in the non-operating position A.

That is, when the current plate 1 is in the non-operating position A,
Since the slider 13 is located at the frontmost end of the opening 33 as shown in FIG. 1, the switch terminal 46a of the second switch 46 is separated from the second cam surface 43b and "cut".
Therefore, the switch terminal 45a of the first switch 45
comes into contact with the first cam surface 43a and is maintained in a "contact" state. Similarly, in the operating position B, the switch terminal 45a of the first switch 45 is
is separated from the first cam surface 43a and becomes "broken", and the switch terminal 46a of the second switch 46 is connected to the opening 3.
The second cam surface 43 of the slider 13 located at the rear end of 3
b, and the "contact" state is maintained. The AND circuit 53 outputs a high level "1" signal to the output side only when high level "1" signals are input to both input terminals, and one input terminal is switched to the switch terminal when the operation is released. is connected to the upright contact _C1 of the operating switch ST that returns to the neutral position, and the other input terminal is connected to the output side of the NOT circuit 57.

The OR circuit 55 operates when a high level "1" signal is input to one of both input terminals and a low level "0" signal is input to the other, and when a high level "1"/"1" signal is input to both input terminals. High level “1” on the output side only when
One input terminal is connected to the falling contact _C2 of the operation switch ST, and the other input terminal is connected to a detection means 59 such as a micro switch. The input side terminal of the NOT circuit 57 is connected to the detection means 59 side, and when a low level "0" or high level "1" signal is input to the input side, a signal opposite to the input signal is generated, for example, a low level signal. When the level is "0", a high level "1" signal is output.

On the other hand, the detection means 59 is provided on the body panel of the automobile 61, and the contact "breaks" when the back door 3 is fully closed.
Therefore, the switch is switched to "contact" when the door is opened, and a high level "1" signal is output when the door is opened.

In the drive device configured in this way, the eighth
As shown in the figure, when the operation switch ST, which is in the neutral position, is operated to the upright contact C1 side, a high level " ₁ " signal is sent from the upright contact _C1 to one side of the AND circuit 53, and to the NOT circuit 57 on the other side. Therefore, the inverted high-level "1" signal is input, and a high-level "1" signal is output to the output side. As a result, the transistor T1 is turned on, and the relay coil LC-1 of the first relay switch RS-1 is excited by the collector current. Relay coil LC-1
Due to the excitation of switch terminal RC ₁ becomes first contact P ₁
The current flowing from the first relay switch RS- ₁ to the second relay switch RS-2 causes the motor circuit ML to rotate forward, drive the operating mechanism 11, and rectify the motor circuit ML. The plate 1 is placed in an upright operating position B. When the current plate 1 is in the operating position B, the first
The switch terminal 45a separates from the cam surface 43a, and the first switch 45 is disconnected. Therefore, the excitation of the relay coil LC-1 is released and the drive motor 19 is stopped. Next, press the operation switch as shown in Figure 9.
When ST is operated to the collapsed contact _C2 side, OR circuit 55
A high level "1" signal from the collapsed contact _C2 is inputted to one side, and a low level "0" signal from the detection means 59 whose contact is disconnected is inputted to the other side, and a high level "1" signal is inputted to the output side. ” signal is output.

As a result, the transistor T2 is turned on and the collector current turns on the second relay switch RS-2.
relay coil LC-2 is energized. By energizing relay coil LC-2, switch terminal RC ₂
is switched from the first contact _P1 to the second contact _P2 , and the motor circuit ML is reversed by the current flowing from the second relay switch RS-2 to the first relay switch RS-1, and the actuating mechanism 11 is The rectifier plate 1 is driven to a laid-down, non-operating position A. When the current plate 1 is in the non-operating position A, the switch terminal 46a is connected from the second cam surface 43b provided on the slider 13 that moves backward.
is released, and the second switch 46 is turned off. Therefore, the excitation of the relay coil LC-2 is released and the drive motor 19 is stopped.

Next, in the operating position B of the current plate 1, the first
As shown in FIG. 0, when the opening/closing body operating portion 5 is operated to bring the contact point of the switch S into contact, the actuator AC is activated and the lock device RK is unlocked, making it possible to open the back door 3. This backdoor 3
The detection means 59 detects the opening of the door, and the switch contact becomes connected. Therefore, a high-level "1" signal is input to one side of the OR circuit 55, a low-level "0" signal from the closed contact _C2 is input to the other, and a high-level "1" signal is input to the output side. signal is output. As a result, the transistor T2 is turned on and the second relay switch is turned on by the collector current.
Relay coil LC-2 of RS-2 is energized. By excitation of relay coil LC-2, switch terminal _RC2 switches from first contact _P1 to second contact _P2 ,
The second relay switch RS-2 is installed in the motor circuit ML.
The current flowing from the switch to the first relay switch RS-1 causes the reverse rotation to drive the actuating mechanism 11 and the rectifier plate 1.
Assume that the body is in the inactive position A when it is lying down. When the current plate 1 is in the non-operating position A, the switch terminal 4 is connected from the second cam surface 43b provided on the slider 13 moving back
6a is released and the second switch 46 is turned off. Therefore, the relay coil LC-2 is de-energized, the drive motor 19 is stopped, and the back door 3 is fully opened with the rectifier plate 1 in the non-operating position A, eliminating the risk of collision with the ceiling or beams of the garage etc. .

Although this embodiment has been described with reference to a back door, it may also be applied to a trunk lid.

[Effect of idea]

As explained above, according to the rectifying plate drive device of the present invention, when the opening/closing body is closed, the operating posture of the rectifying plate is controlled by the first and second control parts that are contacted by the operation of the operation switch. An inactive position is obtained. On the other hand, when the opening/closing body is opened even if you forget to operate the operation switch when the current plate is in the operating position, the second control unit is connected by the door opening signal from the detection means, causing the current plate to fall down and become inoperative. Since the rectifying plate can be positioned in the correct position, it is possible to prevent accidents in which the rectifying plate collides with the garage ceiling, beams, etc. when the opening/closing body is fully opened.
