[Problems to be solved by the invention]
The conventional operating mechanism of the opening / closing body detects the position of the opening / closing body by detecting the position using a position detection switch, detecting the position based on position information such as a potentiometer or pulse count, and driving the opening / closing body such as a motor. Position detection based on speed change information using a load current, hydraulic pressure fluctuation, potentiometer, pulse count, etc. of the apparatus has been performed.
[0006]
However, when a position detection switch is installed, the cost increases due to the installation of the apparatus. In addition, when detecting the open position or the closed position of the opening / closing body based on the speed change information, the operation mechanism of the opening / closing body is loaded, so that the mechanism needs to be strengthened. For example, when a vehicle back door, trunk door, or the like is opened by an operating mechanism of an opening / closing body, an excessive load is applied at the fully opened position, and if the mechanism is not strengthened, there is a possibility of causing poor installation.
[0007]
When position detection is performed based on position information, it can be shared with speed control and pinching detection, etc., so cost increases can be suppressed. Is inferior. For example, if the stop position of the opening / closing body becomes larger than the mechanically fully opened position, it causes a mounting failure such as breakage of the building member of the opening / closing body, and if the stop position of the opening / closing body becomes smaller than the mechanically fully opened position, Deterioration of convenience is caused by the opening degree being smaller than the desired opening degree. Furthermore, since the opening speed of the opening / closing body is not controlled, the automatic opening / closing operation of the opening / closing body is not attractive.
[0008]
For this reason, in consideration of variation in objects and assembly, the initial value of the fully opened recognition position is set closer to the closing side than the mechanical door fully opened position, and the actual opening / closing body stop position (depending on the opening / closing body lifting mechanism) is set. It is conceivable to reset the fully open position of the opening / closing body based on the holding position of the opening / closing body. The opening / closing body is driven up to a driving stop position set a certain amount before the fully open recognition position by the driving means, and then pushed up to the fully open recognition position by an opening / closing body raising mechanism such as an air damper.
[0009]
Here, if it is determined that the opening operation has been performed normally when the opening / closing body is moved to the opening side from the drive stop position, the opening / closing body is opened by the inertial force of the opening / closing body or the lifting force of the air damper after stopping the driving means. In such a case, when the final stop position of the opening / closing body is closer to the closed side than the drive stop position (that is, it is necessary to reset the fully open recognition position to the closed side). However, it is determined that the opening / closing body has been normally opened, and there is a problem in that the full-open position cannot be reset correctly.
[0010]
The present invention has been made in view of the above problems, and an object of the present invention is to realize an operating mechanism that more correctly resets the fully open position in the operating mechanism of the opening / closing body that resets (learns) the fully open position. In the point.
[0011]
[Means for Solving the Problems]
In order to achieve this object, the first feature of the operating mechanism of the opening / closing body according to the present invention is the driving means for opening and closing the opening / closing body, as described in claim 1 of the claims, and the opening / closing mechanism. Position detecting means for detecting the opening position of the body, fully opened position storage means for storing the fully opened position of the opening / closing body, and when the opening / closing body is driven to open by the driving means, the fully opened position storage means stores An operating mechanism of the opening / closing body that stops the driving means at an existing full opening recognition position or a position that is a certain amount before the existing full opening recognition position, and a mechanical full opening position of the opening / closing body from the position at which the driving means is stopped An opening / closing body raising mechanism configured to open the opening / closing body until the opening / closing body is urged in an opening direction, and the opening / closing body is moved within a predetermined time after the opening drive by the driving means is completed. When operated over a certain amount Flip side, the fully open position storage means has characteristics the position of the closing side than the existing fully open recognition position to the point to be set as a new full-open recognition position.
[0012]
That is, the first characteristic configuration of the operating mechanism of the opening / closing body according to the present invention is the position learning function in which the fully-open position storage means sequentially brings the existing fully-open recognition position that is currently recognized closer to the mechanical fully-open position of the opening / closing body. And when the opening / closing body is moved more than a certain amount to the closing side within a certain time after the opening drive by the driving means is finished, a position closer to the closing side than the existing full opening recognition position is set as a new full opening recognition position. Set.
[0013]
When the opening / closing body raising mechanism is used in combination with the driving means, the driving means is stopped at a position before the fully open recognition position, and the opening / closing body raising mechanism performs a slight opening operation so that the opening / closing body is stationary at the mechanical full opening position. ing. However, when the current fully open recognition position (existing fully open recognition position) is very close to the mechanical fully open position or exceeds the mechanical fully open position, the opening amount by the opening / closing body raising mechanism cannot be obtained. There is. In addition, the opening / closing body may be operated not only on the opening side but also on the closing side within a certain time after the opening operation by the driving means is completed. For example, when a malfunction occurs in the driving means and the opening / closing body is driven beyond the mechanically fully opened position, there arises a disadvantage that the mounting portion of the opening / closing body is damaged.
[0014]
Therefore, as in the operation mechanism of the opening / closing body according to the present invention, when the opening / closing body operates more than a certain amount on the closing side within a certain time after the opening drive by the driving means is completed, a new fully opened recognition position (new If the fully open recognition position is set closer to the closed side than the existing fully open recognition position, it is possible to effectively prevent the occurrence of inconveniences such as damage.
[0015]
In the second feature configuration, in addition to the first feature configuration, the new full-open recognition position is a predetermined preset from the existing full-open recognition position. It is in the point which is comprised so that it may be the position of a close side only by fixed amount of .
[0016]
Among the above configurations, the predetermined fixed amount is the opening / closing body when the current full open recognition position (existing full open recognition position) is considered to be extremely close to or beyond the mechanical full open position. Set in consideration of the position that does not cause inconvenience such as breakage of the mounting part. Therefore, as in the second feature configuration, by setting the position on the closing side by a predetermined fixed amount preset from the existing fully open recognition position as a new fully open recognition position (new fully open recognition position) , for example, Inconvenience such as breakage of the mounting portion can be appropriately prevented.
[0017]
As described in claim 3 of the column of claims, the third characteristic configuration includes a driving means for driving the opening / closing body to open, a position detecting means for detecting an opening position of the opening / closing body, When fully opening position storage means for storing the fully open position and when the opening and closing body is driven to open by the driving means, the existing fully open recognition position stored in the fully open position storage means or a certain amount before the existing fully open recognition position. An opening / closing body operating mechanism for stopping the driving means at a position, wherein the opening / closing body is configured to open the opening / closing body from a position where the driving means is stopped to a mechanically open position of the opening / closing body. An opening / closing body raising mechanism for urging in the opening direction, and when the opening / closing body is operated more than a certain amount on the closing side within a certain time after the opening drive by the driving means is completed, the fully opened position storage means Lies in that have configured the position of the closing body after lapse of the predetermined time, or the position of the closing side than the position of the closing body after lapse of said predetermined time to set as a new full-open recognition position.
[0018]
The opening / closing body is driven to open to the mechanical full-open recognition position by the opening / closing body raising mechanism after the opening drive is completed, but then the mechanism is not stabilized at the mechanical full-open position, and a rebounding action may occur. is there. Therefore, as in the third feature configuration, after a certain period of time, for example, after the elapse of time considered to be necessary for the opening and closing body to stably stop, the position of the opening and closing body or a position closer to the closing side is newly set. By setting the position as the fully open recognition position (new fully open recognition position) , the position on the closing side with respect to the mechanical fully open position can always be set as the new fully open recognition position. As a result, inconveniences such as breakage of the mounting portion of the opening / closing body can be prevented more appropriately.
[0019]
As described in claim 4 of the column of claims, the fourth characteristic configuration includes a drive means for driving the opening / closing body to open, a position detection means for detecting the opening position of the opening / closing body, When fully opening position storage means for storing the fully open position and when the opening and closing body is driven to open by the driving means, the existing fully open recognition position stored in the fully open position storage means or a certain amount before the existing fully open recognition position. An opening / closing body operating mechanism for stopping the driving means at a position, wherein the opening / closing body is configured to open the opening / closing body from a position where the driving means is stopped to a mechanically open position of the opening / closing body. An opening / closing body raising mechanism for urging in the opening direction, and the opening / closing body is on the closing side by a predetermined amount or more from the existing fully opened recognition position after a certain period of time has elapsed after the opening drive by the driving means is completed. The case, the full-open position storage means, characterized in that the setting position of the movable member at that time, or the more closed side position than the position of the movable member at that time as a new fully open recognition position.
In addition, it is desirable to set appropriately the time considered that it is required for the said opening / closing body to stop stably in consideration of the dispersion | variation in an object, the dispersion | variation in an assembly, etc.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of an operating mechanism of an opening / closing body according to the present invention (hereinafter abbreviated as “the mechanism of the present invention” as appropriate) will be described with reference to the drawings.
[0021]
The operating mechanism of the opening / closing body according to the present invention will be described with reference to FIGS.
The opening / closing body of the present invention is mainly applied to an opening / closing body having an opening / closing body raising mechanism such as a damper, which is automatically opened by a drive motor, for example, a back door of a one-box car shown in FIG. The present invention can also be applied to ordinary vehicle doors such as truck luggage doors and sliding doors. Further, the present invention can be applied to a door of a general garage, which is a door that opens to information.
[0022]
Below, the example applied to the back door 1 of the one box car shown in FIG. 1 is shown.
As shown in FIG. 2, the back door 1 is attached to the upper rear portion of the vehicle body 12 via a door hinge 1a. Driving means 3 is provided on the vehicle body 12 side, and the back door 1 is operated by operating a main switch 6 provided in the vehicle, a handle switch 8 provided on the back door 1, or a wireless remote control switch (not shown). It can be driven to the open side.
[0023]
2 shows the fully closed state of the back door 1, and FIG. 3 shows the fully opened state.
The drive means 3 mainly includes a drive motor M, a speed reduction mechanism R that adjusts the rotation speed of the drive motor M, an arm member 3b and a rod 4 that connect the speed reduction mechanism R and the back door 1, and the drive. The controller 5 controls the operation of the motor M. An air damper 30 that supports the back door 1 that has been operated to the fully open position is provided across the vehicle body 12 and the back door 1.
[0024]
As the drive means 3, for example, various DC motors are used, and a rotary encoder or the like is provided, and the controller 5 can control the rotation angle and rotation speed of the drive motor M. And the said structure functions as a position detection means to detect the position of the back door 1 after fixed time progress.
[0025]
The operating mechanism of the opening / closing body of the present invention is for learning and recognizing the fully opened position of the back door 1 in order to drive the back door 1 to an appropriate position, particularly when the back door 1 is automatically opened by the driving means 3. is there.
[0026]
Here, for example, the back door 1 of a one-box car is usually provided with left and right air dampers 30 and is configured to support the back door 1 in the fully open position. The air damper 30, which is an example of an opening / closing body raising mechanism, acts in the extending direction when the back door 1 is in the vicinity of the fully open position. Paying attention to the opening operation of the back door 1, in the normal case, the back door 1 is first opened and driven by the drive motor M to the fully open recognition position or the drive stop position set a certain amount before the fully open recognition position. The drive motor M includes, for example, a clutch using an electromagnetic coupling, and the clutch is disconnected when the drive is stopped. The back door 1 that has lost the restraint opens upward by the extension force of the air damper 30 and stops at the mechanically fully open position.
[0027]
In general, it is preferable that the movement of the back door 1 stops at the driving stop position. However, in reality, the drive stop position is set closer to the closing side than the mechanical fully open position, and a certain amount thereafter is opened by the air damper 30 or the like to prevent an excessive opening operation by the drive motor M. Yes. Thus, by providing the air damper 30, it is possible to stop the drive by the drive motor M and prevent the back door 1 from being damaged, and to reliably open the back door 1 to the mechanically fully opened position. Yes. Therefore, the opening operation by the air damper 30 as described above always exists.
Therefore, the learning mode of the mechanism of the present invention mainly aims to reduce the opening operation of the air damper 30 as much as possible and realize an opening operation with good appearance of the back door 1.
[0028]
The learning mode of the mechanism of the present invention will be described with reference to FIGS. FIG. 4 is a schematic diagram showing the operation of the back door 1, and FIGS. 5 and 6 are flowcharts for causing the controller to learn the fully open position.
[0029]
[First learning mode]
In the first learning mode of the mechanism of the present invention, for example, after the drive motor M, which is an example of the drive means 3, drives the back door 1 and the opening operation of the back door 1 is completed (# 11, # 12), a certain period of time After the elapse of T (s) (# 13), the position of the back door 1 is detected (# 14), and when this position is closed by a certain amount or more from the current full open recognition position, the position is closed from the current full open recognition position. The side position is recognized as a new fully opened recognition position (# 15).
[0030]
In this learning mode, a position closer to the predetermined amount D (arbitrary positive number) than the current fully open recognition position is set as a new fully open recognition position. The predetermined amount D is preferably set appropriately so that the new fully open recognition position is set to a position closer to the closing side than the stop position (current position) of the opening / closing body.
[0031]
Further, the position (current position) of the back door 1 after a certain period of time or a position closer to the closing side than the current position may be recognized as a new fully opened recognition position. Here, it is desirable that the predetermined time is appropriately set in consideration of vehicle variation, assembly variation, and the like for a time period during which the opening / closing body is stably stopped. In this case, it is possible to set a position where the opening / closing body stably stops as a new fully open recognition position.
[0032]
The detection of the position of the back door 1 after the elapse of a certain time in this learning mode is performed after T (s) has elapsed since the end of the opening operation of the back door 1 by the driving means 3, but after the elapse of the certain time, Alternatively, it may be performed a plurality of times in the vicinity thereof. In such a case, misrecognition of position detection can be prevented.
[0033]
[Second learning mode]
As shown in FIG. 6, the second learning mode of the mechanism of the present invention is after the opening operation of the back door 1 by the driving means 3 is completed (# 21, # 22) and until a certain time T (s) elapses. (# 24), the position of the back door 1 is detected (monitored) (# 23), and when the back door 1 moves more than a certain amount on the closing side, a position on the closing side of the predetermined amount D is newly set from the current fully opened recognition position. Is recognized as a fully open recognition position (# 25).
[0034]
Here, in the first learning mode, the position of the opening / closing body is detected after a lapse of T (s) time. However, in this learning mode, the opening / closing body is detected at any time until T (s) elapses. Permits the learning of the position of the fully opened recognition position when it moves to the closing side by a certain amount or more from the current fully opened recognition position. Further, in this learning mode, the position of the opening / closing body is detected constantly or at regular intervals shorter than T (s). In other words, the opening / closing body moves to the open side by a certain amount or more from the current full open recognition position due to the opening of the door or the distortion of the driving means or the inertial force, then moves to the close side by rebounding, and after the elapse of T (s) In the first learning mode, the fully open recognition position is not set in the first learning mode, but in the present learning mode, the fully open recognition position is set. In other words, the fully open recognition position can be brought close to the mechanical fully open position by appropriately responding to more complicated situations.
[0035]
Further, the setting of the new fully opened recognition position is not limited to the position on the closing side by the predetermined amount D from the current fully opened recognition position, as in the case of the first learning mode. A position closer to the closing side than the current position may be recognized as a new fully opened recognition position.
[0036]
The fixed time in this learning mode refers to the time from the end of the opening operation of the back door 1 by the driving means 3 to the time after T (s) elapses, but the position detection (monitoring) is always performed until T (s) elapses. It is not necessary to perform this, and a period during which position detection is not performed until after the elapse of T (s) may be arbitrarily set.
[0037]
According to the mechanism of the present invention, the fully open recognition position can be brought close to the mechanical fully open position without damaging the drive mechanism of the opening / closing body. That is, when the opening / closing body is used, the fully open recognition position is changed greatly to the open side, and the opening amount of the air damper 30 cannot be obtained. For example, the open drive stop position by the drive means 3 exceeds the mechanical fully open position. Even in the case, the fully open recognition position can be brought close to the mechanical fully open position. Further, even when the fully open recognition position is set to be far open from the mechanical fully open position, it is easy to correct the fully open position after that, so it is not necessary to assemble the opening / closing body strictly. Assembling man-hours can be reduced.
