Japanese Patent Laying-Open No. 2006-049845

  However, in the above prior art, when the slope member is deployed in a state where the slope member is housed in the vehicle interior, the locked state by the lock mechanism is once released in the inverted state of the slope member, and then the slope member is deployed. The transition is made. For this reason, the operation of the slope member is complicated.

  The present invention has been made in consideration of the above facts, and an object of the present invention is to provide a vehicle slope device that can be more easily operated when the state of the slope member is shifted.

  In order to solve the above-described problem, the vehicle slope device according to the first aspect of the present invention is provided along the vehicle width direction with respect to the lower periphery of the back door opening formed at the rear end of the vehicle. A back door lower part that is supported rotatably about a single shaft part and opens and closes a lower side of the back door opening, and a closed state in which the lower part of the back door is closed by being provided integrally with the lower part of the back door. A first slope member which is in an upright state and is in an unfolded state in which the lower portion of the back door is opened, and a second shaft disposed along the vehicle width direction with respect to the first slope member In the luggage compartment provided at the rear of the vehicle in the upright state of the first slope member, and disposed along the horizontal direction in the retracted state or along the vehicle vertical direction. And standing up In the deployed state of the first slope member, the second slope member that is deployed with the first slope member, and the first slope member when the first slope member is shifted from the deployed state to the upright state. The first slope member is maintained in the upright state after allowing the first slope member to rotate, and in the first locked state, the first slope member is rotated from the upright state to the deployment direction. When the first locking mechanism to be controlled and the second slope member are shifted from the retracted state to the standing state, the second slope member is maintained in the standing state after allowing the second slope member to rotate. A second lock mechanism that is in a second locked state and restricts rotation of the second slope member from the upright state to the retracted direction in the second locked state; A circuit unit including: a first energization circuit that releases the first lock state by the first lock mechanism by energization; and a second energization circuit that releases the second lock state by the second lock mechanism by energization; A storage mode in which the first slope member is in the upright state and the second slope member is in the retracted state, and the first slope member is in the upright state; Any one of a standing mode in which the second slope member is in the standing state, and a deployment mode in which the first slope member is in the deployed state and the second slope member is in the deployed state. And a mode selection switch that enables selection.

  In the slope device for a vehicle according to the first aspect of the present invention, the back is formed around the first shaft portion disposed along the vehicle width direction with respect to the lower peripheral portion of the back door opening formed at the rear end of the vehicle. The lower part of the door is rotatably supported. The lower side of the back door opening is opened and closed by the lower portion of the back door.

  A first slope member is integrally provided at the lower portion of the back door. The first slope member is in an upright state in a closed state in which the lower portion of the back door is closed, and is in an expanded state in an open state in which the lower portion of the back door is opened. With respect to the first slope member, the second slope member is rotatably supported around a second shaft portion disposed along the vehicle width direction. The second slope member is placed along the horizontal direction in the luggage compartment provided at the rear of the vehicle in the upright state of the first slope member, or is placed in the stowed state or placed in the up-down direction of the vehicle. The And in the expansion | deployment state of a 1st slope member, it is set as an expansion | deployment state with the said 1st slope member.

  In the present invention, a first lock mechanism and a second lock mechanism are provided. When the first locking mechanism shifts the first slope member from the deployed state to the upright state, after allowing the first slope member to rotate, the first locking member is maintained in the upright state to be in the first locked state. . And in this 1st locked state, rotation to the expansion | deployment direction from the upright state of a 1st slope member is controlled.

  On the other hand, the second lock mechanism allows the second slope member to rotate in the second locked state after allowing the second slope member to rotate when shifting the second slope member from the retracted state to the standing state. And And in this 2nd locked state, rotation to the storing direction from the standing state of a 2nd slope member is controlled.

  Furthermore, this invention has a circuit part provided with the 1st electricity supply circuit and the 2nd electricity supply circuit. The first energization circuit is set to release the first lock state by the first lock mechanism, and the second energization circuit is set to release the second lock state by the second lock mechanism. In addition, a mode selection switch is electrically connected to the circuit portion. With this mode selection switch, any one of a storage mode, a standing mode, and a deployment mode can be selected.

  Here, in the storage mode, the first slope member is in the upright state and the second slope member is in the storage state. In the standing mode, the first slope member is in an upright state and the second slope member is in a standing state. Further, in the deployment mode, the first slope member is in the deployed state, and the second slope member is in the deployed state.

  By the way, when making a 2nd slope member transfer from an accommodation state to an expansion | deployment state, a 2nd slope member is changed to an expansion | deployment state through an upright state from a storage state. For this reason, in the second locking mechanism, when the second slope member is rotated from the retracted state to the standing state, the second slope member is allowed to be in the second locked state after allowing the second slope member to rotate. That is, the standing state of the second slope member is maintained. For this reason, when the second slope member is shifted from the retracted state to the standing state, the second slope member is brought into the second locked state and the standing state of the second slope member is maintained, and the second slope member and the first slope member are integrated. The

  On the other hand, in the first lock state, the rotation of the first slope member from the upright state to the deployment direction is restricted. Therefore, the circuit unit is set so that the first lock state is released by selecting the development mode with the mode selection switch. As a result, the first slope member is not restricted from rotating in the deployment direction from the upright state, and the second slope member and the first slope member are integrated with the second slope member and the first slope member. The member can be deployed.

  Therefore, when shifting the second slope member from the retracted state to the expanded state, the second slope member can be rotated at a stroke.

  Further, when the second slope member is shifted from the expanded state to the retracted state, the second slope member is shifted from the expanded state to the retracted state via the standing state. Here, in the expanded state of the second slope member, the first slope member is also in the expanded state together with the second slope member. And in the standing state of a 2nd slope member, a 1st slope member is made into an upright state.

  In the first locking mechanism, when the first slope member is shifted from the deployed state to the upright state, after allowing the first slope member to rotate, the first slope member is set to the first locked state, and the first slope member The upright state is maintained. That is, when shifting the second slope member from the deployed state to the standing state, after allowing the first slope member to rotate, the first slope member is set to the first locked state, and the first slope member is set to the upright state. Thus, the second slope member is raised.

  On the other hand, in the second locked state, the rotation of the second slope member from the standing state to the retracted direction is restricted. Therefore, the circuit unit is set so that the second lock state is released when the storage mode is selected by the mode selection switch. As a result, the second slope member is not restricted from rotating in the retracted direction from the standing state, and the second slope member can be retracted.

  Therefore, when shifting the second slope member from the expanded state to the retracted state, the second slope member can be rotated at a stroke.

  That is, when the second slope member is shifted from the retracted state to the expanded state, and when the second slope member is shifted from the expanded state to the retracted state, the second slope member passes through the standing state. For this reason, in the present invention, when the second slope member transitions from the standing state to the deployed state, and when the second slope member transitions from the standing state to the retracted state, the standing state of the second slope member is released. There is no need to operate.

  By the way, about the 1st slope member here, "it is provided integrally with the back door lower part", the 1st slope member may be comprised by the back door lower part itself, or a 1st slope member is a back door. It means that it may be formed of a member different from the lower part, and may be fixed and integrated with the lower part of the back door.

  Here, as shown in FIG. 4A, a tailgate release switch 90 protrudes from the extended portion 44 of the tailgate 18 on the movement path of the deck board 50. Therefore, when the deck board 50 is raised from the retracted state, the deck board 50 comes into contact with the tailgate release switch 90 and the tailgate release switch 90 is pressed. When the tailgate release switch 90 is pressed, the tailgate 18 can be deployed (described later).

  Further, a slope solenoid (second lock mechanism) 75 is provided in the extending portion 44 of the tailgate 18. As shown by a two-dot chain line in FIG. 2, the slope solenoid 75 is configured such that the deck board 50 is held (locked) by the tail gate 18 in the standing state of the deck board 50.

  Accordingly, when the tail gate 18 is rotated to the vehicle rear side and the lower side around the shaft portion 26 in the standing state of the deck board 50, the deck board 50 is rotated integrally with the tail gate 18, and the slope device is provided. 32 is a “deployed state” (see the solid line in FIG. 2). As shown in FIG. 3, a handle 52 is provided at the center in the vehicle width direction of the free end 50 </ b> B of the deck board 50. The deck board 50 is rotated while the handle 52 is held.

  Here, as shown by the solid line in FIG. 2, in the unfolded state of the slope device 32, the side 36 </ b> A of the tailgate inner panel 36 of the tailgate 18 on the side of the cargo compartment 30 and the side of the deck board 50 opposite to the deck surface 50 </ b> C. The surface 50D is the upper surface and is arranged continuously. These surfaces 36A and 50D are hereinafter referred to as slope surfaces 36A and 50D, and the bicycle 124 (see FIG. 10B) can pass through the slope surface 36A and the slope surface 50D as the slope surface 54 of the slope device 32. It is said.

  The slope surface 36A configured by the tailgate inner panel 36 and the slope surface 50D configured by the deck board 50 are set to be substantially flush with each other. Further, the slope surfaces 36A, 50D are designed to provide an anti-slip function. For example, the slope surfaces 36A, 50D extend along the vehicle width direction and are arranged along the vehicle front-rear direction on the slope surfaces 36A, 50D. A plurality of ribs and the like are formed.

  Further, in the unfolded state of the slope device 32, the free end portion 50B of the deck board 50 can be grounded to the ground GL, and the free end portion 50B of the deck board 50 is grounded to the ground GL. The slope surface 54 is continuously inclined from the floor portion 34 of the cargo compartment 30 and is gently inclined downward toward the vehicle rear side. The deck board 50 is formed of, for example, FRP (reinforced fiber plastic), but is not limited thereto, and may be formed of, for example, a metal such as aluminum.

  On the other hand, as shown in FIG. 5, a pair of deck side trims 64 extend along the vehicle front-rear direction on both sides of the cargo compartment 30 in the vehicle width direction. The said deck side trim 64 is made into the interior member of the vehicle 10, and has comprised the oblong rectangle shape seeing from the vehicle rear side in this embodiment. Here, only the deck side trim 64 on the left side of the vehicle is shown.

  On the inner wall surface 64A on the inner side in the vehicle width direction of the deck side trim 64, horizontal ribs 66 projecting inward in the vehicle width direction are respectively extended along the vehicle front-rear direction. An end portion 50A in the vehicle width direction of the deck board 50 shown in FIG. 4A can be brought into contact with the horizontal rib 66. When the deck board 50 comes into contact with the horizontal rib 66, the deck board 50 is The downward movement of the horizontal rib 66 is restricted. A deck switch 70 projects from the upper surface 66A of the horizontal rib 66, and the deck switch 70 is pressed when the deck board 50 abuts (described later).

  On the rear surface 64B of the deck side trim 64, a slope release switch (first pressing switch) 72 protrudes on the movement locus of the tailgate 18 shown in FIG. For this reason, when the tailgate 18 stands upright from the unfolded state, the tailgate 18 comes into contact with the slope release switch 72 and the slope release switch 72 is pressed. When the slope release switch 72 is pressed, the deck board 50 can be moved forward (described later).

  In addition, the position of the horizontal direction of the horizontal rib 66 is set so that it may become substantially the same height as the axial part 48 (refer FIG. 2). Accordingly, the deck board 50 is disposed along the substantially horizontal direction in a state where the deck board 50 is tilted forward and in contact with the horizontal rib 66. In this manner, the state in which the deck board 50 is arranged along the substantially horizontal direction in the cargo compartment 30 is referred to as the “storage state” of the deck board 50 (slope device 32).

  In the retracted state of the deck board 50, as shown by the solid line in FIG. 1, the upper surface side of the deck board 50 is the deck surface 50C, and luggage can be placed on the deck surface 50C. In the present embodiment, the horizontal portion 42 of the tailgate 18 described above is set to have substantially the same height as the deck surface 50C of the deck board 50 in the retracted state.

  On the other hand, as shown in FIG. 5, a changeover switch (mode selection switch) 74 is provided on the upper surface 64 </ b> C of the deck side trim 64. The change-over switch 74 enables the slope device 32 to be switched between a “storage” mode, a “stand-up” mode, and a “deployment” mode.

  Here, as shown in FIGS. 1, 2, and 18, a wire harness 73 is connected to the battery 71 mounted on the front portion 69 of the vehicle 10 in the slope device 32. The circuit part in FIG. Hereinafter, the wire harness 73 is referred to as a “circuit portion 73”.

  As shown in FIG. 6A, the circuit unit 76 includes a storage circuit (second energization circuit) 78 and a deployment circuit (first energization circuit) 80. The storage circuit 78 includes a storage contact. 82 is provided, and the development circuit 80 is provided with a development contact 84. The changeover switch 74 allows the storage circuit 78 or the development circuit 80 to be switched, and the main contact 86 provided in the circuit section 76 can be connected to the storage contact 82 and the development contact 84. The main contact 86 can be connected to the standing contact 88 in addition to the storage contact 82 and the deployment contact 84 by the changeover switch 74. However, no circuit is connected to the standing contact 88.

  That is, by switching the changeover switch 74, the main contact 86 can be connected to the storage contact 82, the standing contact 88, and the deployment contact 84. When the main contact 86 is connected to the storage contact 82, the storage circuit 78 can be closed, and when the main contact 86 is connected to the expansion contact 84, the expansion circuit 80 can be closed. . However, even if the main contact 86 is connected to the standing contact 88, no circuit is closed.

  The storage circuit 78 includes a deck switch 70, a slope release switch 72, a storage indicator 122, and a slope solenoid 75 in addition to the storage contact 82. The deployment circuit 80 includes a deck switch 70, a tailgate release switch (second pressing switch) 90, a deployment indicator 120, and a tailgate solenoid (first lock mechanism) 85 in addition to the deployment contact 84. ing.

  The deck switch 70 is disconnected from the storage circuit 78 and the deployment circuit 80 in a pressed state, and the storage circuit 78 and the deployment circuit 80 are in a state in which the deck switch 70 is pressed. Each is configured to open (become a so-called open circuit).

  As shown in FIG. 4B, the tailgate solenoid 85 is provided at a case 92 in which a fixed iron core (not shown) is accommodated, a plunger 94 that can be moved in and out of the case 92, and a distal end portion of the plunger 94. The cam member 96 and a coil spring 98 that biases the cam member 96 away from the case 92 are configured.

  When the tailgate solenoid 85 is energized, the plunger 94 is attracted to the stationary iron core by the magnetic force of the stationary iron core and accommodated in the case 92, and the cam member 96 is energized by the coil spring 98 via the plunger 94. Against the case 92 side. On the other hand, in the tailgate solenoid 85, when the energized state is released, the magnetic force of the fixed iron core disappears and the plunger 94 protrudes from the case 92 by the urging force of the coil spring 98, and the cam member 96 is connected via the plunger 94. It moves in a direction away from the case 92.

  Here, the case 92 is accommodated in an accommodating portion 100 formed along the vehicle width direction on the lower peripheral side of the back door opening 12. On the other hand, the tailgate 18 is provided with a storage portion 102 so as to face the storage portion 100 in a state where the tailgate 18 is upright. A cam member 96 can be stored in the storage portion 102.

  When the tailgate solenoid 85 is not energized, the plunger 94 protrudes from the case 92 as described above, so that the state where the cam member 96 is accommodated in the accommodating portion 102 via the plunger 94 is maintained. Is done. That is, the state (upright state) in which the tailgate 18 is locked to the lower periphery of the back door opening 12 is maintained (the locked state of the tailgate 18). When the tailgate solenoid 85 is energized in the locked state of the tailgate 18, the cam member 96 is accommodated in the accommodating portion 100, and the locked state of the tailgate 18 is released.

  The cam member 96 has a sector shape with a central angle of 90 degrees in plan view, and an end surface 96A on the plunger 94 side is formed linearly along the vehicle front-rear direction, and the front end 96B is along the vehicle width direction. It is formed in a straight line. On the other hand, the rear end 96C of the cam member 96 is an arcuate cam surface 96C. Hereinafter, the rear end 96C of the cam member 96 is referred to as a cam surface 96C.

  Therefore, with the tailgate 18 locked to the lower periphery of the back door opening 12, the tailgate 18 is pivoted toward the vehicle rear side around the shaft portion 26 (see FIG. 1) of the door hinge lower portion 24 (so-called deployment). ) The cam member 96 does not move. That is, the locked state of the tailgate 18 is maintained.

  On the other hand, although not shown, the plunger 94 and the cam member 96 protrude from the case 92 when the tailgate 18 is unfolded and the tailgate solenoid 85 is not energized. For this reason, the cam member 96 will be arrange | positioned on the movement locus | trajectory of the tailgate 18 at the time of making the tailgate 18 stand upright.

  Therefore, when the deployed tailgate 18 is to be erected, the tailgate inner panel 36 of the tailgate 18 comes into contact with the cam surface 96 </ b> C of the cam member 96. In this way, when the tailgate inner panel 36 abuts against the cam surface 96C, the cam member 96 is pressed toward the case 92 against the biasing force of the coil spring 98 via the cam surface 96C. The pressing force (F) is applied, and the cam member 96 is accommodated in the accommodating portion 100.

  As a result, when the tailgate 18 is erected, the tailgate 18 is allowed to pass even if the cam member 96 is disposed on the movement locus of the tailgate 18, so that the accommodating portion 102 of the tailgate 18 can be connected to the back door opening 12. It can be made to oppose the accommodating part 100 of the side. That is, the deployed tailgate 18 can be erected. When the accommodating portion 102 of the tailgate 18 faces the accommodating portion 100 on the back door opening 12 side, the cam member 96 is restored by the urging force of the coil spring 98, and the cam member 96 is placed in the accommodating portion 102 of the tailgate 18. Is housed. As a result, the tailgate 18 is locked.

  On the other hand, as shown in FIG. 4A, the slope solenoid 75 is similar to the tailgate solenoid 85 in that a case 104 in which a fixed iron core (not shown) is housed and a plunger that can be moved in and out of the case 104. 106, a cam member 108 provided at the distal end portion of the plunger 106, and a coil spring 98 (see FIG. 4B) that urges the cam member 108 in a direction to separate the cam member 108 from the case 104. .

  The case 104 is attached to the tailgate inner panel 36 side. A bracket 110 is attached to the extended portion 44 of the tailgate inner panel 36, and the case 104 is fixed via the bracket 110.

  Here, the cam member 108 has a fan shape with a central angle of 90 degrees in a plan view, like the cam member 96, but the rear end 108A of the cam member 108 is formed linearly along the vehicle width direction. The front end 108B is an arcuate cam surface 108B. Hereinafter, the front end 108B of the cam member 108 is referred to as a cam surface 108B.

  On the other hand, the deck board 50 is rotatably supported with respect to the shaft portion 48 of the hinge portion 46 shown in FIG. 1 in a state where the tailgate 18 is upright. In the state where the solenoid for slope 75 is not energized, the plunger 106 protrudes from the case 104 and the cam member 108 is disposed at a position separated from the case 104, but the cam member 108 is disposed on the movement track of the deck board 50.

  Further, a gap t corresponding to the thickness of the deck board 50 is provided between the rear end 108A of the cam member 108 and the tailgate inner panel 36, and the deck board 50 is disposed in the gap t. It is possible. Then, with the deck board 50 disposed in the gap t, the deck board 50 is locked in a standing state with respect to the tail gate 18 (the locked state of the deck board 50). That is, the deck board 50 is integrated with the tailgate 18.

  Thus, in the locked state of the deck board 50, the cam member 108 does not move even if the deck board 50 is rotated (so-called storage) around the shaft portion 48 (see FIG. 1). That is, the deck board 50 is kept locked. When the slope solenoid 75 is energized in the locked state of the deck board 50, the cam member 108 moves to the case 104 side and retracts from the movement path of the deck board 50. Thereby, the locked state of the deck board 50 is released. That is, when the slope release switch 72 is pressed, the deck board 50 can be moved forward (stored).

  In contrast, although not shown, the plunger 106 and the cam member 108 protrude from the case 104 in a state where the deck board 50 is retracted and the slope solenoid 75 is not energized. For this reason, the cam member 108 is disposed on the movement path of the deck board 50 when the deck board 50 is erected.

  Therefore, when the stored deck board 50 is erected, the deck surface 50C of the deck board 50 comes into contact with the cam surface 108B of the cam member 108. As a result, a pressing force that presses the cam member 108 toward the case 104 acts against the urging force of the coil spring 98 (see FIG. 4B) on the cam member 108 via the cam surface 108B. The cam member 108 is retracted from the movement path of the deck board 50. Therefore, the locked state of the deck board 50 is released.

  Therefore, when the stored deck board 50 is erected, the deck board 50 can be allowed to pass even if the cam member 108 is disposed on the movement path of the deck board 50. When the deck board 50 is passed, the coil spring 98 (see FIG. 4B) of the cam member 108 is restored and the cam member 108 protrudes from the case 104. Accordingly, the deck board 50 can be disposed in the gap t between the rear end 108A of the cam member 108 and the tailgate inner panel 36. That is, the deck board 50 can be locked and the deck board 50 can be integrated with the tailgate 18.

  Here, operation | movement of the vehicle slope apparatus which concerns on this Embodiment is demonstrated along FIGS. 6A-6I. The numbers indicated by () at the top of the figure are serial numbers, and will be described in the order of these numbers.

  In FIG. 6A (0), the slope device 32 is in the storage state of the deck board 50, and the mode selection by the changeover switch 74 is “storage”. At this time, the tailgate 18 is brought into an upright state, the slope release switch 72 is pressed through the tailgate 18, and the slope release switch 72 is connected to the storage circuit 78. Thereby, the storage circuit 78 is a so-called closed circuit, and the storage circuit 78 is energized. On the other hand, the deck switch 70 is pressed by the deck board 50, and the deck switch 70 is not connected to the storage circuit 78.

  Further, in the retracted state of the deck board 50, the deck board 50 is separated from the tailgate release switch 90, and the tailgate release switch 90 protrudes. In this state, the tailgate release switch 90 is not connected to the development circuit 80 (non-connected state), and the development circuit 80 is a so-called open circuit.

  By the way, when the changeover switch 74 is switched to “storage”, the main contact 86 is connected to the storage contact 82 in the circuit unit 76, but the deck switch 70 is not connected to the storage circuit 78. It has become. For this reason, the storage circuit 78 is an open circuit, and the slope solenoid 75 is not energized (non-energized state indicated by a dotted line). That is, the cam member 96 of the slope solenoid 75 projects from the case 92. Further, the storage indicator 122 is turned off, and the slope solenoid 75 is in a state in which the cam member 108 protrudes from the case 104.

  Next, as shown in FIG. 6A (1), the mode selection by the changeover switch 74 is switched from “storage” to “development”. Thereby, in the circuit part 76, the main contact 86 is connected to the unfolding contact 84, but here, since the tailgate release switch 90 is in a non-connected state, the slope solenoid 75 is in a non-energized state. ing. That is, the cam member 108 of the slope solenoid 75 protrudes from the case 104.

  Then, as shown in FIG. 6A (2), the handle 52 of the deck board 50 is lifted. As a result, the deck board 50 is separated from the deck switch 70, and the deck switch 70 protrudes and is connected to the storage circuit 78.

  6B (3), the slope solenoid 75 is in a non-energized state, and the cam member 108 of the slope solenoid 75 is in a state of protruding from the case 104. For this reason, when the handle 52 of the deck board 50 is further lifted and the deck board 50 is rotated to the vehicle rear side, the deck board 50 comes into contact with the cam surface 108B of the cam member 108.

  Further, as shown in FIG. 6B (4), when the deck board 50 is rotated to the rear side of the vehicle, the cam member 108 is resisted against the biasing force of a coil spring (not shown) via the cam surface 108B. Pressed to the case 104 side, the deck board 50 passes.

  As shown in FIG. 6B (5), when the deck board 50 passes through the cam member 108, the coil spring is restored and the deck board 50 is disposed between the cam member 108 and the tailgate 18. For this reason, the deck board 50 is maintained in the standing state (second locked state). In the standing state of the deck board 50, the tailgate release switch 90 is pressed and connected to the development circuit 80.

  Thereby, the deployment circuit 80 is a closed circuit, and the deployment indicator 120 and the tailgate solenoid 85 are energized. Therefore, the deployment indicator 120 is lit, and the tailgate solenoid 85 is stored in the storage portion 100 as the cam member 96 moves to the case 92 side. Thereby, the locked state of the tailgate 18 is released, and the tailgate 18 can be deployed.

  Further, as shown in FIG. 6C (6), when the tailgate 18 is separated from the slope release switch 72, the slope release switch 72 protrudes and is not connected to the storage circuit 78. Here, since the main contact 86 is connected to the development contact 84, the storage circuit 78 is an open circuit and is not energized.

  Therefore, the slope solenoid 75 is in a non-energized state, and the cam member 108 is protruded from the case 104. That is, the deck board 50 is in a locked state. For this reason, when the deck board 50 is rotated to the vehicle rear side, the tailgate 18 can be developed together with the deck board 50.

  Further, as shown in FIG. 6C (7), the deck board 50 is rotated to the vehicle rear side, and the tailgate 18 is developed together with the deck board 50. That is, the slope device 32 is developed and the slope device 32 can be used.

  Next, as shown in FIG. 6D (8), the mode selection by the changeover switch 74 is switched from “deployment” to “standing”. Thereby, in the circuit unit 76, the main contact 86 is connected to the standing contact 88. In this case, none of the circuits is closed. Accordingly, the deployment indicator 120 and the tailgate solenoid 85 are in a non-energized state. For this reason, the deployment indicator 120 is turned off, and the cam member 96 protrudes from the housing portion 100 of the tailgate solenoid 85.

  As shown in FIG. 6D (9), the handle 52 of the deployed slope device 32 is lifted. Then, as shown in FIG. 6E (10), the slope device 32 is rotated forward of the vehicle. Here, as described above, the tailgate solenoid 85 is in a non-energized state, and the cam member 96 protrudes from the case 92. For this reason, the tailgate 18 contacts the cam surface 96 </ b> C of the cam member 96.

  Further, as shown in FIG. 6E (11), when the slope device 32 is further rotated toward the front side of the vehicle, the biasing force of the coil spring 98 is applied via the tail gate 18 and the cam surface 96C of the tail gate solenoid 85. Accordingly, the cam member 96 is accommodated in the accommodating portion 100.

  Then, as shown in FIG. 6E (12), the accommodating portion 102 on the tailgate 18 side is opposed to the accommodating portion 100 on the back door opening 12 side. Thereby, the cam member 96 is accommodated in the accommodating portion 102 of the tail gate 18 by the restoring force of the coil spring 98 (see FIG. 4B), and the tail gate 18 is locked to the lower periphery of the back door opening 12. (First locked state). This is a so-called upright state of the tailgate 18, where the slope release switch 72 is pressed via the tailgate 18 and connected to the storage circuit 78.

  Next, as shown in FIG. 6F (13), the mode selection by the changeover switch 74 is switched from “standing” to “deploying”. Thereby, in the circuit part 76, the main contact 86 is connected to the expansion contact 84, and the expansion circuit 80 is closed.

  Here, since the tailgate release switch 90 is pressed and connected to the deployment circuit 80, the deployment circuit 80 is a so-called closed circuit, and the deployment indicator 120 and the tailgate solenoid 85 are energized. For this reason, the deployment indicator 120 is lit, and the tailgate solenoid 85 is housed in the housing portion 100 as the cam member 96 moves to the case 92 side. Thereby, the locked state of the tailgate 18 is released, and the tailgate 18 can be deployed.

  As shown in FIG. 6F (14), when the tailgate 18 is separated from the slope release switch 72, the slope release switch 72 protrudes and is not connected to the storage circuit 78. Here, since the main contact 86 is connected to the unfolding contact 84, the storage circuit 78 is not energized. Therefore, when the deck board 50 is maintained in the locked state and the deck board 50 is rotated to the vehicle rear side, the tailgate 18 is developed together with the deck board 50.

  Further, as shown in FIG. 6F (15), the deck board 50 is rotated to the vehicle rear side, and the tailgate 18 is developed together with the deck board 50. That is, the slope device 32 is developed and the slope device 32 can be used.

  Next, as shown in FIG. 6G (16), the mode selection by the changeover switch 74 is switched from “deployment” to “storage”. As a result, in the circuit section 76, the main contact 86 is connected to the storage contact 82, and the storage circuit 78 is closed. For this reason, the development circuit 80 is an open circuit and is not energized. Accordingly, the deployment indicator 120 and the tailgate solenoid 85 are in a non-energized state. As a result, the deployment indicator 120 is turned off, and the cam member 96 projects from the accommodating portion 100 of the tailgate solenoid 85.

  On the other hand, in the storage circuit 78, the slope release switch 72 protrudes and is not connected to the storage circuit 78. That is, the storage circuit 78 is an open circuit, and the slope solenoid 75 is not energized. For this reason, the deck board 50 is kept locked (the deck board 50 is locked).

  As shown in FIG. 6G (17), the handle 52 of the deck board 50 is lifted. Then, as shown in FIG. 6H (18), when the slope device 32 is rotated forward, the tailgate 18 comes into contact with the cam surface 96C of the cam member 96 of the tailgate solenoid 85.

  Further, as shown in FIG. 6H (19), when the slope device 32 is rotated to the front side of the vehicle, the cam member 96 resists the biasing force of the coil spring 98 via the cam surface 96C. Housed inside.

  Accordingly, as shown in FIG. 6H (20), when the accommodating portion 102 on the tailgate 18 side is opposed to the accommodating portion 100 on the back door opening 12 side, the coil spring 98 (see FIG. 4B) is restored. Due to the force, the cam member 96 is accommodated in the accommodating portion 102 of the tailgate 18, and the tailgate 18 is locked to the lower periphery of the back door opening 12 (first locked state). This is a so-called upright state of the tailgate 18, where the slope release switch 72 is pressed via the tailgate 18 and connected to the storage circuit 78.

  Thereby, the storage circuit 78 is a so-called closed circuit, the storage indicator 122 and the slope solenoid 75 are energized, the storage indicator 122 is lit, and the slope solenoid 75 moves the cam member 108 to the case 104 side. Then, the deck board 50 is retreated from the movement locus. Thereby, the locked state of the deck board 50 is released, and the deck board 50 can be rotated (stored) with respect to the tailgate 18.

  Then, as shown in FIG. 6I (21), when the deck board 50 is rotated to the front side of the vehicle, the deck board 50 is separated from the tailgate release switch 90, the tailgate release switch 90 protrudes, and the development circuit 80 Is disconnected. At this time, the development circuit 80 is an open circuit.

  Further, as shown in FIG. 6I (22), when the deck board 50 is rotated forward, the deck board 50 passes through the cam member 108 of the slope solenoid 75. As shown in FIG. 6I (23), when the deck switch 70 is pressed by the deck board 50, the deck switch 70 is disconnected from the storage circuit 78.

  As a result, the storage circuit 78 is opened, and the slope release switch 72, the storage indicator 122, and the slope solenoid 75 are deenergized. Accordingly, the storage indicator 122 is turned off, and the slope solenoid 75 is in a state where the cam member 108 protrudes from the case 104. This state is the same as the state of FIG. 6A (0).

(Operation and effect of vehicle slope device)
Next, with reference to FIG. 4 (A) and FIG. 5, about the effect | action and effect of the slope apparatus 32 which concern on this Embodiment, the example is shown to FIG. 7 (A), (B)-FIG. This will be described below according to (B).

  As shown in FIGS. 7A and 7B, the tailgate 18 side can be opened in the state where the back door upper portion 16 is opened. Here, in the storage state of the deck board 50, the deck board 50 is arranged in a substantially horizontal direction in the cargo compartment 30. In this state, the luggage 68 can be placed on the deck surface 50 </ b> C of the deck board 50.

  A horizontal portion 42 is provided at the center of the tailgate 18 in the vehicle width direction, and the horizontal portion 42 is set to be substantially the same height as the deck surface 50C of the deck board 50 in the retracted state. The luggage 68 placed on the deck surface 50C can be taken out of the vehicle simply by sliding the luggage 68 along the deck surface 50C. That is, when the luggage 68 in the luggage compartment 30 is taken out, it is not necessary to lift the luggage 68, so that the luggage 68 can be easily taken out even when the luggage 68 is heavy.

  Next, when the slope device 32 is deployed, the back door upper portion 16 is opened as shown in FIG. In the following drawings, the back door upper portion 16 is not shown. In the state of FIG. 8A, “Store” is selected for the changeover switch 74. For this reason, in FIG. 8B, the changeover switch 74 is switched to “deployment”.

  Next, as shown in FIG. 9A, the handle 52 of the deck board 50 is lifted with one hand. Then, as shown in FIG. 9B, when the deck board 50 is raised, the tailgate release switch 90 is pressed. Further, the deck board 50 is maintained in the standing state (second locked state). At this time, the tailgate solenoid 85 is energized, the tailgate 18 is unlocked, and the tailgate 18 can be deployed together with the deck board 50.

  Then, as shown in FIG. 10 (A), when the slope device 32 configured to include the deck board 50 and the tailgate 18 is deployed, the slope device 32 is moved over the slope device 32 as shown in FIG. 10 (B). The bicycle 124 passes and the bicycle 124 can be accommodated in the luggage compartment 30.

  As shown in FIG. 11A, the changeover switch 74 is switched to “standing” in a state where the bicycle 124 is housed in the luggage compartment 30. 11B, when the slope device 32 is erected, the tailgate 18 passes through the cam member 96 of the tailgate solenoid 85 and is brought into an upright state. Locked to. At this time, the tailgate release switch 90 is pressed, but the standing switch 78 and the unfolding circuit 80 are in an open circuit state because the change-over switch 74 is selected to “rise”. For this reason, the deck board 50 is maintained in the standing state.

  Next, as shown in FIG. 12A, when the bicycle 124 in the cargo compartment 30 is lowered, the changeover switch 74 is switched to “deployment”. Then, as shown in FIG. 12 (B), the handle 52 of the deck board 50 is pulled to the vehicle rear side, and the slope device 32 is developed as shown in FIG. 13 (A). As a result, the bicycle 124 is lowered from the cargo compartment 30 via the slope device 32 as shown in FIG.

  Next, in FIG. 14A, the changeover switch 74 is switched to “storage”. Then, as shown in FIG. 14B, when the slope device 32 is lifted and the slope device 32 is raised as shown in FIG. 15A, the tailgate 18 is in an upright state as described above. In this case, the slope solenoid 75 is energized and the locked state of the deck board 50 is released. As a result, as shown in FIG. 15B, the deck board 50 can be rotated forward and stored.

  As described above, in the present embodiment, as shown in FIGS. 1 and 2, the first slope member is configured by the tailgate inner panel 36 of the tailgate 18. Then, the tailgate 18 is brought into an upright state in the closed state, and is brought into a deployed state in the opened state in which the tailgate 18 is opened. A deck board 50 is rotatably supported by the tailgate 18 around a shaft portion 48 disposed along the vehicle width direction. The deck board 50 is arranged along the horizontal direction in the cargo compartment 30 in the upright state of the tailgate 18, and is placed in the stowed state or arranged in the up-down direction of the vehicle. Further, the deck board 50 is in an expanded state together with the tailgate 18 when the tailgate 18 is expanded.

  In the present embodiment, as shown in FIG. 4A, a tailgate solenoid 85 as a first lock mechanism and a slope solenoid 75 as a second lock mechanism are provided. When the tailgate solenoid 85 shifts the tailgate 18 from the deployed state to the upright state, after allowing the tailgate 18 to rotate, the tailgate 18 is maintained in the upright state to be in the locked state. When the tailgate 18 is locked, the tailgate 18 is restricted from rotating from the upright state to the unfolding direction.

  On the other hand, the slope solenoid 75 allows the deck board 50 to be disposed between the cam member 108 and the tail gate 18 after allowing the deck board 50 to rotate when the deck board 50 is shifted from the stowed state to the standing state. The deck board 50 is maintained in a standing state to be in a locked state. Then, in the locked state of the deck board 50, the rotation of the deck board 50 from the standing state to the retracting direction is restricted.

  Further, in the present embodiment, as shown in FIG. 6A, the circuit unit 76 includes a deployment circuit 80 as a first energization circuit and a storage circuit 78 as a second energization circuit. The development circuit 80 is set so as to release the locked state of the tailgate 18 by the tailgate solenoid 85 when energized, and the storage circuit 78 releases the locked state of the deck board 50 by the slope solenoid 75 when energized. Is set to In addition, a changeover switch 74 is electrically connected to the circuit portion 76.

  In the storage mode, the tailgate 18 is upright and the deck board 50 is in the storage state. In the standing mode, the tailgate 18 is set upright and the deck board 50 is set up. Further, in the unfolding mode, the tailgate 18 is unfolded and the deck board 50 is unfolded.

  By the way, for example, as illustrated in FIGS. 6A to 6C, when the deck board 50 is shifted from the stored state to the expanded state, the deck board 50 is shifted from the stored state to the expanded state through the standing state. Therefore, when the deck solenoid 50 is rotated from the retracted state to the standing state, the slope solenoid 75 maintains the standing state of the deck board 50 after allowing the deck board 50 to rotate (the deck board 50 is Locked). For this reason, when the deck board 50 is shifted from the stowed state to the standing state, the deck board 50 is maintained in the second locked state, and the deck board 50 and the tailgate 18 are integrated.

  On the other hand, in the first locked state, the tailgate 18 is restricted from rotating from the upright state to the unfolding direction. Therefore, the circuit unit 76 is set so that the first lock state is released by selecting the unfolding mode by the changeover switch 74. As a result, the tail gate 18 is not restricted from rotating in the deployment direction from the upright state, and the deck board 50 and the tail gate 18 are deployed in a state where the deck board 50 and the tail gate 18 are integrated. Can do.

  Therefore, when the deck board 50 is shifted from the retracted state to the expanded state, the deck board 50 can be rotated at a stroke.

  As shown in FIGS. 6G to 6I, when the deck board 50 is shifted from the expanded state to the retracted state, the deck board 50 is shifted from the expanded state to the retracted state through the standing state. Here, in the unfolded state of the deck board 50, the tailgate 18 is also unfolded together with the deck board 50. When the deck board 50 is in the standing state, the tailgate 18 is in an upright state.

  In the tailgate solenoid 85, when the tailgate 18 is shifted from the deployed state to the upright state, after allowing the tailgate 18 to rotate, the tailgate 18 is locked, and the tailgate 18 is maintained in the upright state. That is, when the deck board 50 is shifted from the unfolded state to the standing state, after allowing the tail gate 18 to rotate, the tail gate 18 is locked, the tail gate 18 is brought into an upright state, and the deck board 50 is brought into the standing state. Is done.

  On the other hand, the slope solenoid 75 is restricted from rotating in the retracted direction from the standing state of the deck board 50. For this reason, in the circuit part 76, when the storage mode is selected by the changeover switch 74, the second lock state is set to be released. As a result, the deck board 50 is not restricted from rotating in the storage direction from the standing state, and the deck board 50 can be stored.

  Therefore, when the deck board 50 is shifted from the expanded state to the retracted state, the deck board 50 can be rotated at a stroke.

  That is, when the deck board 50 is shifted from the retracted state to the expanded state and when the deck board 50 is shifted from the expanded state to the retracted state, the deck board 50 passes through the standing state. For this reason, in the present embodiment, operations such as releasing the standing state of the deck board 50 when the deck board 50 is shifted from the standing state to the deployed state and when the deck board 50 is shifted from the standing state to the retracted state. There is no need to do.

  As a result, as described above, when the deck board 50 is shifted from the retracted state to the expanded state and when the deck board 50 is shifted from the expanded state to the retracted state, the deck board 50 can be rotated at a stroke. When the state of the slope device 32 is shifted, the slope device 32 can be easily operated.

  In this embodiment, the unfolding circuit 80 is set to release the upright state of the tail gate 18 by energization, and the storage circuit 78 is set to release the standing state of the deck board 50 by energization. In other words, the tailgate 18 can be maintained in an upright state when the development circuit 80 is not energized, and the deck board 50 can be maintained in an upright state when the storage circuit 78 is not energized.

  Further, in the present embodiment, when the storage mode is selected by the changeover switch 74, the storage circuit 78 is energized by the circuit unit 76 and the standing state of the deck board 50 is released. That is, the deck board 50 can be rotated in the storage direction. When the expansion mode is selected by the changeover switch 74, the expansion circuit 80 is energized by the circuit unit 76, and the upright state of the tailgate 18 is released. That is, the tailgate 18 can be rotated in the deployment direction.

  In the present embodiment, when the standing mode is selected by the changeover switch 74, the expansion switch 80 is set so as not to be connected to either the development circuit 80 or the storage circuit 78. The circuit including the development circuit 80 and the storage circuit 78 can be simplified as compared with the case where the circuit 80 or the storage circuit 78 is connected.

  Further, in the present embodiment, a slope release switch 72 is provided as a first press switch, and a tailgate release switch 90 is provided as a second press switch. The slope release switch 72 is pressed in the process in which the tailgate 18 is in an upright state, and the tailgate release switch 90 is pressed in the process in which the deck board 50 is in an upright state. In the circuit section 76, the storage circuit 78 can be closed by pressing the slope release switch 72, and the deployment circuit 80 can be closed by pressing the tailgate release switch 90.

  For example, when the tailgate 18 is in the upright state, the slope release switch 72 is pressed, but when the storage circuit 78 is energized while the slope release switch 72 is pressed, the deck board 50 is released from the standing state. . As a result, when the tailgate 18 is brought upright, the deck board 50 can be rotated in the retracted direction at once.

  Further, the tailgate release switch 90 is pressed in the standing state of the deck board 50. However, when the development circuit 80 is energized with the tailgate release switch 90 pressed, the tailgate 18 is released from the upright state. Is done. As a result, when the tailgate 18 is brought upright, the deck board 50 can be rotated together with the tailgate 18 in the unfolding direction.

  Thus, the storage circuit 78 of the slope solenoid 75 is connected by pressing the slope release switch 72, and the unfolding circuit 80 of the tailgate solenoid 85 is connected by pressing the tailgate release switch 90. Thereby, the state transition of the tail gate 18 and the deck board 50 can be performed separately, and the state can be shifted in stages between the tail gate 18 and the deck board 50.

  Further, in the present embodiment, the circuit unit 76 energizes the storage circuit 78 only when the tailgate 18 is in the upright state by the slope release switch 72. Thus, since the standing state of the deck board 50 is released when the storage circuit 78 is energized, the deck board 50 can be rotated in the storing direction when the tailgate 18 is brought upright.

  That is, in the present embodiment, in the process of shifting the deck board 50 from the unfolded state to the retracted state, the deck board 50 rotates in an integrated state with the tail gate 18 until the tail gate 18 becomes an upright state. The deck board 50 is easy to operate.

  Further, in the present embodiment, the circuit unit 76 energizes the development circuit 80 only when the deck board 50 is in the standing state by the tailgate release switch 90. As described above, when the development circuit 80 is energized, the upright state of the tailgate 18 is released. Therefore, when the deck board 50 is raised, the tailgate 18 can be rotated in the deployment direction.

  That is, in this embodiment, when the deck board 50 is raised in the process of shifting the deck board 50 from the retracted state to the expanded state, the deck board 50 rotates in an integrated state with the tailgate 18. The board 50 is easy to operate.

  Further, in the present embodiment, the slope release switch (first press switch) 72 is a press switch disposed on the turning locus of the tail gate 18, and the slope release switch 72 is pressed by the tail gate 18 coming into contact therewith. As a result, the development circuit 80 is connected. The tailgate release switch (second press switch) 90 is a tailgate release switch 90 disposed on the turning locus of the deck board 50, and the tailgate release switch 90 is pressed when the deck board 50 abuts. As a result, the storage circuit 78 is connected.

  In this way, for example, the development circuit 80 and the storage circuit 78 are connected in conjunction with the turning operation of the tailgate 18 and the deck board 50, so that the development circuit can be realized with a simple configuration. 80. Connection or disconnection of the storage circuit 78 can be switched.

  On the other hand, in the present embodiment, as shown in FIG. 3, the lower end 16 </ b> A of the back door upper portion 16 is positioned behind the upper end 18 </ b> B of the tailgate 18 in the vehicle longitudinal direction with the back door 14 closed. ing. For this reason, as shown in FIGS. 7A and 7B, the luggage 68 can be placed on the deck board 50 in the storage mode by simply opening the back door upper part 16 side, or from the deck board 50. The luggage 68 can be taken out.

  In the present embodiment, as shown in FIG. 1, the tailgate inner panel 36 constitutes the inner wall surface of the tailgate 18, and is not shown, but the first slope member is separate from the tailgate 18. Compared with the case where is provided, the space of the cargo compartment 30 can be expanded.

  Further, in the circuit unit 76 shown in FIG. 6, a warning may be issued if the tailgate 18 and the deck board 50 are rotated without changing the changeover switch 74. That is, the operation of the tailgate 18 and the deck board 50 is prevented from being shifted in a state in which the tailgate solenoid 85 and the slope solenoid 75 as a lock mechanism that should not be released are unlocked, thereby preventing erroneous operation. can do.

  In the present embodiment, energization of the deployment circuit 80 and the storage circuit 78 is interrupted while the vehicle is traveling. Therefore, the locked state in which the tailgate 18 is maintained in the upright state and the locked state in which the deck board 50 is maintained in the upright state are maintained. For this reason, it is possible to suppress the locked state of the tailgate solenoid 85 and the slope solenoid 75 that should not be released during traveling from being accidentally released.

  Further, in the present embodiment, as shown in FIGS. 1 and 2, the deck board 50 is supported so as to be rotatable around a shaft portion 48 provided in the tailgate 18. The surface used when placing the load (not shown) (deck surface 50C) and the surface used as a part of the slope surface 54 (slope surface 50D) are used according to the application. Can be changed.

  For example, although not shown, when the deck surface 50C and the slope surface 50D are used as the same surface, the bicycle passes through the slope surface 50D, and therefore the slope surface 50D is dirty and the luggage is loaded on the slope surface 50D as it is. May not be able to be placed. However, in the present embodiment, since the surfaces used for the deck surface 50C and the slope surface 36A are different, such a problem does not occur.

  In the present embodiment, an inclined surface 62 is formed on the free end 50 </ b> B of the deck board 50. Thereby, the level | step difference for the board thickness of the deck board 50 can be made small between the free end part 50B of the deck board 50, and the ground GL, but this inclined surface 62 is not necessarily required.

  By the way, in this embodiment, as shown in FIG. 10B, the bicycle 124 can pass through the slope device 32, but is not limited to the bicycle 124. For example, although not shown, the slope device 32 may pass a wheelchair, a stroller, or the like.

  Further, in this embodiment, a tailgate solenoid 85 is provided as a first lock mechanism, a case 92 is disposed on the back door opening 12 side, and a cam member 96 can be accommodated on the tailgate 18 side. However, the case 92 may be disposed on the tail gate 18 side, and the cam member 96 may be accommodated on the back door opening 12 side.

  In the present embodiment, as shown in FIG. 4A, the tailgate solenoid 85 is used as the first lock mechanism and the slope solenoid 75 is used as the second lock mechanism. It is only necessary that the board 50 can be locked in the upright state and the upright state, and the present invention is not limited to this.

  For example, as shown in FIGS. 16 and 17, an electric lock 128 including a striker 126 may be used. Here, the striker 126 is provided on the back door opening 12 side and the electric lock 128 is provided on the tail gate 18 side. However, the electric lock 128 is provided on the back door opening 12 side, and the tail gate is provided. A striker 126 may be provided on the 18th side.

There is an unfolded state (see the solid line in FIG. 2) in which the deck board 50 rotates to the vehicle rear side and is in contact with the ground GL, but the state of the deck board 50 is not limited to this.

  For example, as shown in FIG. 1, the deck board 50 is not only rotatable about the shaft portion 48 with respect to the tailgate 18, but is not shown, but in the standing state of the deck board 50. The deck board 50 may be slidable in the vertical direction with respect to the tailgate. Thereby, in the standing state of the deck board 50, the deck board 50 can be opposed to the tailgate 18 in the front-rear direction of the vehicle (the storage state of the deck board 50).
