Description

  The present invention relates to a vehicle floor device, and more particularly, to a vehicle provided with a fixed step for getting on and off so as to have a step at an entrance because the floor of a passenger compartment is set relatively high. The present invention relates to a vehicle floor device having a structure that closes a space on a fixed step for getting on and off and enlarges an effective area of the vehicle floor.

  In general, in a vehicle such as a one-box car, the floor of the passenger compartment is set to be relatively high, and therefore, a boarding / alighting fixing step is provided at the entrance / exit side of the vehicle floor so as to be one step lower. However, in the conventional boarding / alighting step structure in which the boarding / alighting step is provided at the entrance / exit of the vehicle floor, the effective area of the vehicle floor is reduced by the provision of the boarding / alighting step. There was a problem. That is, seats are installed on the side and rear vehicle floors of the getting-on / off fixing step, but a recessed space is formed by providing the getting-on / off fixing step at the feet of passengers seated on these seats. In addition, there is a problem that the occupant is forced to take an unnatural seating posture, or that the load loaded in the vehicle falls into the recessed space. In view of these circumstances, various vehicle floor structures have been proposed (see, for example, Patent Document 1 and Patent Document 2).

For example, the boarding / alighting step structure described in Patent Document 1 is provided above the boarding / alighting fixing step and is freely rotatable at the edge of the vehicle floor in a vehicle having a boarding / unloading fixing step that is one step lower than the vehicle floor. Is provided with a step cover. In the boarding / alighting step structure described in Patent Document 1, when the slide door is opened, a wire connected to the step cover is tensioned in the side surface direction of the step, and the step cover is located between the vehicle floor and the fixed step for getting on and off. The fixed step for getting on and off is made to appear at the entrance and exit. Further, when the sliding door is closed, the tension of the wire disappears, the step cover is deployed so as to be aligned on the same plane as the vehicle floor, the recessed space above the fixed step for getting on and off is closed, and the vehicle floor is closed. The area is increased. Moreover, in the raising / lowering assistance apparatus of patent document 2, it becomes the structure to which a step is raised / lowered by the drive means using an electric motor in the orthogonal | vertical direction. And, when getting on and off, the step is lowered by the driving means and it is easy to get on and off, and when not getting on, the step is raised by the driving means and the effective area of the vehicle floor is enlarged. It has become.

  Further, as shown in FIG. 8B, when the movable floor 20 is moved upward from the vehicle floor 62, the position detection switch 24 moves away from the movable piece 24a and the plunger 24b. It is configured to be switched off. The position detection switch 24 is configured to output a position detection signal to the central control unit 30 described later when the switch is turned on. Further, the position detection switch 24 is configured to be in contact with the inner wall of the housing portion 65 and to be switched on when the movable floor 20 is housed in the housing portion 65 (see FIG. 6). Has been. Further, the position detection switch 24 is switched on even when the movable floor 20 comes into contact with an obstacle or the like while the movable floor 20 is being deployed or stored, and also plays a role of detecting pinching of the movable floor 20.

  A housing portion 65 for housing the movable floor 20 is disposed on the vehicle compartment side of the slide door 64, and a storage detection switch 28 for detecting that the movable floor 20 is stored in the housing portion 65. Is provided. The storage detection switch 28 is constituted by, for example, a plunger type switch similar to the position detection switch 24 described above, and is switched on when the movable floor 20 is stored in the storage portion 65 and is stored. The storage detection signal can be output to the central control unit 30. The storage detection switch 28 is not limited to being disposed in the accommodating portion 65, and can be disposed on the movable floor 20, for example.

  As shown in FIG. 9, the hinge 23 of the movable floor 20 is provided with a pinching detection switch 25 comprising a pressure-sensitive contact type for detecting a collision with an obstacle or detecting pinching of an occupant. Yes. That is, a recess 21b is provided on the back surface 21a of the floor portion 21, and a first contact 25a is provided in the recess 21b. The hinge 23 is formed with a protrusion 23a, and a second contact 25b is provided at the tip of the protrusion 23a.

It is in the state. On the other hand, when a load is applied to the movable floor 20, as shown in FIG. 9B, the first contact 25a and the second contact 25b come into contact with each other, so that the sandwiching detection switch 25 sandwiches the central control unit 30. The detection signal is output.

  In addition, the movable floor mechanism part 10 which consists of the said structure is comprised by the unit reduced in size as mentioned above. For this reason, the movable floor mechanism part 10 can be easily assembled to the slide door 64 of the vehicle 60. Therefore, in a vehicle equipped with a vehicle floor device, a significant structural change or the like is not imposed on the mounting portion of the slide door 64 with respect to a vehicle not equipped with the vehicle floor device. For this reason, the vehicle floor apparatus S in this example is suitable for optional equipment (equipment that can be freely selected according to the user's desire) in the vehicle 60 and the like.

  The central control unit 30 includes, for example, a CPU for performing various calculations, a ROM that stores a program for operating the CPU, and an RAM that temporarily stores information processed by the CPU. It consists of a circuit. The central control unit 30 includes a power supply unit according to detection signals from the position detection switch 24 and the pinching detection switch 25 described above, detection signals from a door opening / closing detection switch 67 and a door opening / closing operation detection unit 68 described later, and the like. 40 is configured to be controlled. The central control unit 30 may be integrated into a central control device (not shown) provided in the vehicle 60. Detailed operation of the central control unit 30 will be described later.

  The power supply unit 40 is configured by a power supply device including a battery provided in the vehicle 60, and a predetermined power is supplied to the drive motor 11 of the movable floor mechanism unit 10 according to the power supply command signal from the central control unit 30. It is comprised so that a voltage can be applied. The door open / close detection switch 67 detects the open / closed state of the slide door 64. When the slide door 64 is in a closed state, the door open / close detection switch 67 outputs a door close signal to the central control unit 30 and the slide door 64 is opened. Sometimes, it is configured to output a door opening signal to the central control unit 30. The door opening / closing operation detection unit 68 receives a door opening / closing signal transmitted from the outside of the vehicle by a portable electronic key such as a keyless entry or a door opening / closing signal output from a door opening / closing operation switch provided in the room. A detection signal corresponding to the reception state of the open / close signal is transmitted to the central control unit 30.

  Note that, as the vehicle 60 according to the present embodiment, for example, a one-box car in which the floor of the passenger compartment is set relatively high, a so-called minivan, or the like is suitable. An entrance / exit fixing step 63 is provided at the entrance / exit 61 of the vehicle 60 so as to be one step lower than the vehicle floor 62. A slide door 64 that is slidable along the vehicle front-rear direction is disposed at the entrance 61 of the vehicle 60. The slide door 64 is automatically operated by an electric door opening / closing device (not shown) provided in the vehicle 60. It is designed to open and close.

Next, the operation of the vehicle floor apparatus S configured as described above will be described.
As shown in FIG. 4, in the vehicle floor apparatus S of the present embodiment, when the slide door 64 is in a closed state, the movable floor 20 is unfolded so as to cover the upper side of the fixed boarding step 63 for getting on and off. It has become. In this state, the entire vehicle floor 62 including the movable floor 20 is flat, and the vehicle floor area is sufficiently secured. As shown in FIG. 4, when the slide door 64 is closed, a door opening operation is performed from the outside of the vehicle using a keyless entry (not shown), or a room is opened by a door opening operation switch (not shown) provided in the room. When the door opening operation is performed, the door opening operation signal output by the door opening operation is detected by the door opening / closing operation detection unit 68, and the door opening operation detection signal is sent from the door opening / closing operation detection unit 68 to the central control unit 30. Is output. When the central control unit 30 detects the door opening operation detection signal, the central control unit 30 recognizes that the sliding door 64 has been opened.

  When the central control unit 30 recognizes that the opening operation of the slide door 64 has been performed, the central control unit 30 outputs a power supply command signal to the power supply unit 40. When detecting the power supply signal, the power supply unit 40 applies a voltage having a predetermined polarity to the drive motor 11 of the movable floor mechanism unit 10. Thereby, the drive motor 11 operates and the drive gear 12 rotates in the R1 direction together with the rotating shaft 11a. When the drive gear 12 rotates in the R1 direction, the reduction gear 13 meshed with the drive gear 12 rotates in the R2 direction, whereby the crank 15 rotates in the R3 direction with the first connecting rod 14 as the rotation axis. Move. Since the crank 15 and the crank 16 are connected by the first connecting rod 14 and the second connecting rod 17 as described above, the crank 16 (see FIG. 3) is also turned as the crank 15 rotates. As in the case of 15, it rotates in the R3 direction.

  Thus, when the crank 15 rotates in the R3 direction, the movable floor 20 rotates in the R4 direction with the rotation shaft 23c of the hinge 23 as the rotation axis, as shown in FIG. When the crank 15 further rotates in the R3 direction, the movable floor 20 is accommodated in the accommodating portion 65 as shown in FIG. At this time, the back surface 22a of the support portion 22 of the movable floor 20 and the inner side surface 64a of the slide door 64 are substantially continuous planes, so that the movable floor 20 does not protrude into the interior of the vehicle 60. Further, the connecting rod 18 and the crank 15 are in a straight line so that they do not protrude into the interior of the vehicle 60. Although not particularly shown in FIG. 6, the connecting rod 19 and the crank 16 (see FIG. 3) are also in a straight line so as not to protrude into the interior of the vehicle 60. Thus, when the movable floor 20 is stored, the entire movable floor 20 is accommodated in the accommodating portion 65, so that the design in the vehicle is not impaired even if the movable floor 65 is provided in the vehicle.

  As shown in FIG. 6, when the movable floor 20 is accommodated in the accommodating portion 65, the position detection switch 24 provided at the swing end 20 a of the movable floor 20 comes into contact with the inner wall of the accommodating portion 65. As a result, the position detection switch 24 is turned on. In this way, when the position detection switch 24 is turned on, a position detection signal is output from the position detection switch 24 to the central control unit 30. At the same time, the movable floor 20 contacts the storage detection switch 28, and the storage detection switch 28 is turned on. As a result, a storage detection signal is output from the storage detection switch 28 to the central control unit 30.

  In this way, when the central control unit 30 detects the position detection signal output from the position detection switch 24 and the storage detection signal output from the storage detection switch 28, the movable floor 20 Is detected, a power supply stop signal is output from the central control unit 30 to the power supply unit 40, and the rotation of the drive motor 11 is stopped. Then, the central control unit 30 outputs an operation permission signal to an electric door opening / closing device (not shown). The electric door opening and closing device electrically opens the sliding door 64 when detecting the operation permission signal. As a result, as shown in FIG. 7, the slide door 64 protrudes to the outside of the vehicle and slides toward the vehicle rear side. Note that sliding of the slide door 64 is not limited to being electrically driven. In addition, when the electric door opening and closing device receives an operation permission signal from the central control unit 30, the door holding mechanism (not shown) may be released so that the sliding door 64 can be manually opened and closed.

  As described above, when the slide door 64 is slid toward the vehicle rear side, the entrance / exit 61 appears on the side of the vehicle 60, and the occupant can get out of the vehicle or get into the vehicle. Become. In addition, when the slide door 64 is slid rearward, the movable floor 20 is accommodated in the accommodating portion 65, so that the occupant can get on and off using the fixing step 63 for getting on and off appearing in the room. It is. Furthermore, as described above, the movable floor 20 is accommodated in the accommodating portion 65 without protruding toward the passenger compartment, so that the design in the vehicle is not impaired. For example, when the occupant is in a state of getting on the fixed boarding step 63, the movable floor 20 is shifted from the retracted state to the expanded state, and the movable floor 20 is in contact with an obstacle or the like during the transition. When this happens, the pinching detection switch 25 immediately detects pinching of an obstacle or the like, and the drive of the drive motor 11 is reversed. Thereby, the movable floor 20 is accommodated in the accommodating part 65, and it can cancel | release the pinching state of a passenger | crew's leg | foot. At this time, the movable floor 20 accommodated in the accommodating portion 65 may be unfolded again after stopping for a certain period of time, or unfolded in response to the slide door 64 being closed again by the occupant. Also good.

  On the other hand, when the occupant performs the door closing operation, when the slide door 64 is closed as shown in FIG. 6 from the state where the slide door 64 is opened as shown in FIG. Is output to the central control unit 30, and the central control unit 30 recognizes that the slide door 64 is closed. When the central control unit 30 detects the door closing signal, the central control unit 30 outputs a power supply command signal to the power supply unit 40. When the power supply unit 40 detects the power supply signal, the central control unit 30 applies a voltage having a predetermined polarity to the drive motor 11. Is applied. As described above, the polarity at this time is opposite to that when the rotating shaft 11a of the drive motor 11 is rotated in the R1 direction. As a result, the drive gear 12 rotates in the R5 direction together with the rotation shaft 11a of the drive motor 11, and the reduction gear 13 rotates in the R6 direction, so that the crank 15 uses the first connecting rod 14 as the rotation shaft in the R7 direction. To turn.

  In this way, when the crank 15 rotates in the R7 direction, the movable floor 20 rotates in the R8 direction as shown in FIG. 5, and eventually the movable floor 20 becomes fixed as shown in FIG. It will be in the developed state developed so that the upper part of may be covered. At this time, the swinging end 20a of the movable floor 20 is in contact with the support portion 66 provided on the vehicle floor 62, thereby restricting the lowering of the movable floor 20. Further, the position detection switch 24 comes into contact with the side wall portion 66a formed in the support portion 66, and thereby the switch is turned on. In this way, when the position detection switch 24 is turned on, a position detection signal is output from the position detection switch 24 to the central control unit 30.

As described above, when only the position detection signal output from the position detection switch 24 is detected in the central control unit 30 in a state where the storage detection signal from the storage detection switch 28 is not output, the movable floor 20 is detected in the central control unit 30.
