Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to the detection of opening and closing of a door, and particularly to a door that is rotatably connected to a door frame or a vehicle body by a hinge and is connected to a door check mechanism. Regarding door opening/closing detection.

(Prior Art) For example, this type of vehicle door is equipped with a switch means such as a limit switch on the door opening edge of the vehicle body, and when the switch means opens or closes when the door is opened, a foot light is turned on or a warning lamp is turned on. I'm lighting it up. Furthermore, in recent vehicles, the posture of the driver seat is controlled in conjunction with the opening and closing of the door to make it suitable for getting on and off the vehicle.

(Problem to be Solved by the Invention) Conventionally, as mentioned above, a switch means such as a limit switch is installed at the edge of the door opening, and the switch operator is pressed when the door is closed, and released when the door is opened. Because of this, rainwater and car wash water can easily wet the limit switch and cause it to rust. Also, since the switch is exposed when the door is fully opened, it is easily destroyed.
Furthermore, the switch is closed only when the door is fully closed, which is one point in the range from fully open to fully closed, and the switch is open at other opening degrees, and the switch is turned on at a predetermined opening in the range from fully closed to fully open. It is not possible to detect the door opening range that is converted into a binary value when the switch is turned off. For example, if the above-mentioned driver seat posture control is performed in response to the opening/closing of a conventional limit switch of this type, the driver seat rotates to the pickup position for accepting the driver before the door is fully opened, Since there is a risk of collision, it is necessary to adopt a separate technical means, such as installing a separate door fully open detection switch and driving the driver's seat after detecting that the door is fully open. Such a problem can be improved by using a detection mechanism that detects the range from the fully closed door to the fully open door by dividing the door into regions, and can arbitrarily set the region boundaries.

The present invention provides a door opening/closing detection device which prevents a switch means from getting wet and damaged, and which can obtain detection signals segmented into regions from fully closed to fully open, and can arbitrarily set the region boundaries. The purpose is to

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the door opening/closing detection device of the present invention includes an abutment means 38 integrated with a portion of the check lever 36 of the door 10 that reciprocates inside the door;
Guide means 40 arranged inside the door along the movement trajectory of said abutment means 38; comprising a switch action means 42 for exerting a factor on the switch means to bring about an electrical switching action;
0, at least a portion of which protrudes into the locus of movement of the abutting means 38 and engages with the abutting means 38 when the abutting means 38 moves in one direction of reciprocating motion; 39; urging means 41 for urging the engaging means 39 in a direction opposite to the one direction; stopping means 43 for stopping the movement of the engaging means 39 in the opposite direction at a predetermined position; and the guide The switch operating means 42 is disposed on the side of the means 40, and when the engaging means 39 is not engaged with the abutting means 38, is biased by the biasing means 41, and is in a predetermined position stopped by the stopping means. switch means SWdo for receiving said factor.

In addition, the symbols inside the brackets are used in the examples described later.
These are attached to the corresponding elements shown in the drawings.

(Operation) According to this, the abutment means 38 and the guide means 40, which are the main components, are disposed inside the door, and other elements related thereto are also located inside the door. In the door opening/closing detection device of the invention, rainwater or car wash water will not reach the switch means, and the switch means will not be hit by objects.

Furthermore, since the abutting means 38 is integrated with the portion of the check lever 36 of the door 10 that reciprocates inside the door, the abutting means 38 reciprocates in conjunction with the opening and closing of the door. and during one of the backward movements (for example, backward movement), the engaging means 39 engages with the abutting means 38 and is driven in the same direction (backward movement direction).

By the way, since the urging means 41 urges the engaging means 39 in the opposite direction (forward movement), before the driving (returning movement), the engaging means 39 urges the engaging means 39 in the opposite direction (forward movement). ), the stopping means 43 stops the engaging means 39 at a predetermined position, and at this time the switching means SWdo is in a certain switching state under the influence of the switching means 42.

Therefore, as described above, the forward and backward movement of the check lever 36 when the door is opened and closed causes the abutting means 38 to
When the is reciprocated, during one of the reciprocating movements (backward movement), the engaging means 39 engages with the abutting means 38 at the predetermined position and is driven in the same direction (backward movement direction). 39 reaches a predetermined position by movement in the direction (backward movement direction), the switch acting means 42 of the engaging means 39 separates from the switch means SWdo, and the factor of the switch acting means 42 acts on the switch means SWdo. No longer, switch means
The switching state of SWdo changes to another state. That is, the switching means SWdo switches.

In this state, the movement of the engagement means 39 in that direction (return direction) is completed, and then the abutment means 38 is reversed to move in the other direction (forward direction), and the engagement means 39
9 is driven in the other direction (forward direction) by the biasing means 41 until it reaches the predetermined position. When the movement in the other direction (forward direction) reaches the predetermined position, the switch means SWdo activates the switch action means 4.
In response to said factor of 2, it switches to the previous state. That is, the switching means SWdo switches again. Even if the engaging means 39 moves further in the other direction (forward direction), the engaging means 39 does not engage in that direction and is stopped by the stopping means 43, so that the switching means
SWdo then maintains the same switching state until the abutting means 38 reverses its movement in one direction (reverse direction) and reaches the predetermined position.

Therefore, the switch means remains in one cycle of door opening/closing from a certain point (predetermined position) in the process of movement in one direction to returning to the certain point in the process of movement in the opposite direction. The switching state is maintained, and the switching state is returned to the certain point, and then the movement in one direction is returned to the other switching state until the certain point is reached. The switching between the one switching state and another switching state is as follows.
It is determined by the stopping means 43. That is, it can be set at any position using the stopping means 43.

For example, as in the embodiment described later, the stopping means 43 is set so that the switch acting means 42 of the engaging means 39 stops at the midpoint of the movement trajectory of the abutting means 38 between the door fully closed and fully opened, The urging means 41 urges the engaging means 39, the switch means SWdo is disposed thereon, and the abutting means 38 engages with the engaging means 39 when the abutting means 38 moves in the door closing direction. When the engagement direction is set, the switch action means 42 of the engagement means 39 is at the switch means SWdo position when the door is fully open to 1/2 open.
SWdo detects the switch action means 42.
In the range from half open to fully closed, the contact means 38 drives the engagement means 39 against the biasing force of the biasing means 41, and the switch action means 42 of the engagement means 39 is activated from the switch SWdo. Being in a remote position, the switch means SWdo does not detect the switch action means 42. Therefore, the switch means SWdo generates, for example, a low level L signal between the door fully open and 1/2 open, and generates a high level H signal between the door 1/2 open and fully open. In this way, signals indicating each region obtained by dividing the range from fully open to fully closed door into two are obtained. By shifting the stopping position of the engaging means 39 by the stopping means 43 and the urging means 41 to the fully open side or the fully closed side and accordingly shifting the switch means SWdo, the boundary of the area where the detection signal of the switch means SWdo is switched is fully open. or fully closed.

As described above, according to the present invention, a detection signal can be obtained in which the range from fully open to fully closed door is divided into regions, and the region boundaries can be arbitrarily set.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 shows the appearance of a vehicle equipped with an embodiment of the present invention. A door opening/closing detection device of the present invention is mounted on a driver's door 10 of a vehicle shown in FIG. As shown in FIG. 2, the door 10 has upper and lower hinges 11.
and 12, which are rotatably fixed to the vehicle body. 36 is a door check lever.

In Figure 3a, A-A of Figures 1 and 2.
A line cross-sectional view is shown. A door check 35 is fixed to the door 10, and a check lever 36 whose one end is pivotally connected to the vehicle body passes through the door check 35. Note that the door 10 is pivotally attached to the vehicle body by upper and lower hinges, and rotates within the range of AR2.

Figure 3b shows the cross section taken along line B-B in Figure 3a,
FIG. 3c shows a sectional view taken along the line B--C in FIG. 3a. A stopper 37 and a striker 38 are provided at the other end of the check lever 36, that is, the end that penetrates the door check 35 and enters the space between the outer cover and the inner cover of the door 10 (inner space of the door cover).
is fixed. Striker 3 is installed on door 10.
8, in the movement linked to the door fully opening from the door fully closing, the engager 39 that is engaged and pushed by the striker 38 when the door is fully closed from the door 1/2 open position is moved by the guide bar supported by the arms 43 and 44. 40 so as to be slidable. The engaging element 39 is pushed toward the door check 35 by the coil spring 41, but as shown in FIG. It hits the arm 43 that supports the guide guard 40 and does not move any further toward the door check 35. A magnet 42 is fixed to the engaging element 39, and the Hall IC unit SWdo is disposed at a position opposite to the magnet 42 when the engaging element 39 is at the stop position on the door check 35 side, as shown in FIG. 3c. .

This hall IC unit SWdo is located in the inner space of the door cover, so rainwater, car wash water, etc. do not enter there. When the door 10 is fully open to half open (1/2 open), the permanent magnet 42 is in the hole as shown in Fig. 3c.
The Hall IC unit SWdo outputs a door open signal (earth level L) in response to the magnetic field of the magnet 42, that is, the switching factor, and when the door 10 becomes less than 1/2 open, the Hall IC unit SWdo moves to the right (Fig. 3c), and the Hall IC unit SWdo outputs a door close signal (high level H). In other words, the Hall IC unit
The output of SWdo is L, but when the door is fully closed (less than 1/2 open), the Hall IC unit SWdo
The output of is H.

In this embodiment, as mentioned above, the door 10 is 1/2
When the magnet 42 is open or more, the magnet 42 remains in a position facing the Hall IC unit SWdo and the Hall IC
The unit SWdo generates a switch-on signal (earth level L), and when the door 10 is fully closed less than 1/2 opening, the striker 38 is activated by the check lever 36 entering the door 10. The engaging element 39 is pushed to the right (Figs. 3a to 3c), and the magnet 42 is therefore connected to the Hall IC unit SWdo.
Hall IC unit SWdo generates a switch-off signal (high level H).

In this way, the switch signal is inverted when the door 10 is opened to 1/2 of its fully open position. The guide bar 40 is lengthened to the right, and the hole is lengthened accordingly.
By shifting the IC unit SWdo to the right, the Hall IC unit SWdo inverts the switch signal at an opening smaller than 1/2 opening, and vice versa.
By shifting both units SWdo to the left, the Hall IC unit SWdo inverts the switch signal at an opening larger than 1/2 opening. In this way, the switch signal can be reversed at any degree of opening, including fully closed door and fully open door.

A switch signal can be obtained even if the engager 39, guide bar 40, coil spring 41, and magnet 42 are omitted and the striker 38 is replaced with a magnet, but the switch signal is generated when the magnet (strike 38) faces the Hall IC unit SWdo. Since the switch only generates a switch-on signal, at least a fully closed detection switch (or a fully open detection switch) is additionally added, and the switch-on signal of the Hall IC unit SWdo is counted once, using the state change of this additional switch as the starting point. When the door is 1/2 open or more (or when the door is less than 1/2 open), the door is 1/2 open when the count is 2 times.
It is necessary to determine that the door is less than 2 open (or the door is 1/2 open or more).

In the embodiment described above with reference to the drawings,
The coil spring 41 pushes the engagement element 39 to the left limit position, and this left limit position is the position where the striker 38 hits the engagement element when the door is 1/2 open, and the Hall IC unit SWdo is placed at the limit position. , 1 switch means (hole
A switch signal whose level is inverted at 1/2 opening can be obtained using only the IC unit (SWdo), making it easy to read the signal.

In the above embodiment, the Hall IC unit SWdo is used as the switching means, and the magnet 42 is used as the switching means. You can use it as a body. In these cases, the factor that brings about the switching action is capacitance, a magnetic field, or light. Alternatively, the switch means may be a limit switch or a micro switch, and the switch action means may be a striker that presses the switch's operator (an abutting element that is pressed when an object touches it). In this case, the factor that brings about the switch action is force.

〔Effect of the invention〕

As described above, according to the present invention, rainwater and car wash water will not reach the switch means, and the switch means will not be hit by objects. A detection signal is obtained that divides the range from fully open to fully closed door, and the boundaries of the regions can be set arbitrarily.
