Description

TECHNICAL AREA

[0001] The present invention relates to a device for detecting the opening and closing of a door and to a door opening and closing device. TECHNICAL BACKGROUND

[0002] In a vehicle door opening and closing device according to the following patent document 1, a vehicle door can be opened and closed automatically. This vehicle door opening and closing device includes an interior door opening and closing switch located on an armrest of the door. When a vehicle occupant sets the interior door switch to OPEN or CLOSE, a sensing element of the interior door switch detects the operation of the switch. Upon detection of this action, the drive element for opening and closing the door is activated, thereby opening and closing the door.

[0003] The door opening and closing device disclosed in patent document 2 comprises a door handle which, when actuated, triggers a detection unit. The detection element comprises two pushbuttons arranged on opposite sides of the door handle in the direction of rotation and actuated by a part of the handle located at the outer end of the handle, away from the axis of rotation. The switches of the detection element are arranged such that a distinction can be made between a pulling movement outward from the neutral position toward the vehicle and a pushing movement inward from the neutral position toward the vehicle.

[0004] Patent specification 3 discloses a door opening and closing device that detects the speed at which the door handle is actuated. A magnet is connected to the handle and, when the handle is actuated, moves towards a magnetic sensor. The rotational speed around the axis of actuation can be determined from the induced voltage. State of the Art Document (Patent Document) [Patent Document 1] JP 2005 – 14 839 A [Patent document 2] US 2007 / 0 130 837 A1 [Patent document 3] JP 2004 - 285 712 A SUMMARY OF THE INVENTION Problem to be solved by the invention

[0005] However, the aforementioned vehicle door opening and closing device still has room for improvement in the following aspect. Specifically, the interior door switch in this device is a rocker-type switch.

FORM OF EXECUTION OF THE INVENTION

[0017] The following describes a door opening and closing device according to the present embodiment with reference to the figures. The door opening and closing device is attached to a vehicle V (motor vehicle), as shown in Fig. Figure 1 shows that the arrows UP, FR, and RH, depicted according to the circumstances, indicate the upper, front, and right sides (one side of the vehicle's width direction) of vehicle V, respectively. The terms up and down, forward and reverse, and left and right, used in the following explanation, indicate the vehicle's direction of travel, unless otherwise noted.

[0018] The door opening and closing device is designed as a device for automatically opening and closing a door D (side door) of the vehicle V. The door opening and closing device is designed to include a device 20 for detecting the door opening and closing, a door opening and closing drive unit 60, a door opening and closing position detection device 62 (also known as the "door opening and closing position detection unit"), and a control unit 64. The device 20 for detecting the door opening and closing is mounted on the door D.

[0019] For ease of understanding, the following explanation describes an example in which the device 20 for detecting the door opening and closing is attached to the right front door D of the vehicle V. The front end of the door D is coupled to a front pillar of the vehicle V by a door hinge (not shown) so that it can be opened and closed, with the axis direction corresponding to the upward and downward direction. Specifically, the door D is designed to be opened and closed between a fully closed position, in which the door opening section of the vehicle V is closed, and a fully open position, in which the door opening section is opened by rotating the door fully closed to the right (towards the outer side in the direction of the vehicle's width) from the fully closed position. The individual components of the door opening and closing device are explained below. (Regarding device 20 for detecting door opening and closing)

[0020] The device 20 for detecting the door opening and closing is designed such that it comprises a base 22, a handle 30, a first preload spring 40 as a "first preload element", a second preload spring 42 as a "second preload element", a first switch 44 as a "detection part" and "switch", a second switch 46 as a "detection part" and "switch", and a button cover 52, as shown in Fig. 2 to Fig. Figure 4 shows. The following explanation for the device 20 for detecting the door opening and closing describes a state in which the door D is arranged in the fully closed position. <Hinsichtlich der Grundlage 22>

[0021] As in Fig. 2 to Fig. As shown in Figure 6, the base 22 is essentially formed in the form of a rectangular box, open to the left (towards the interior of the vehicle) and forwards, and fixed to an inner panel (not shown) of the door D. A support axis 24 extends between the upper and lower walls of the rear part of the base 22, forming essentially a cylinder whose axis is oriented vertically. A support element 22A, projecting to the left, is formed integrally on the bottom wall (right wall) of the base 22, with the axially central portion of the support axis 24 also being supported by the support element 22A. An opening 22B, for the arrangement of the first switch 44 and second switch 46 mentioned later, is formed penetrating the bottom wall of the rear part of the base 22.

[0022] On the bottom wall of the base 22 is a left-projecting, essentially cylindrical base stop part 22C (see Fig. 6 (B)) is formed on the front edge part of the opening 22B. A left-facing recess is formed on the left end face of the base stop part 22C, and a mounting hole 22C1 is formed penetrating through its bottom surface. A first pad 26 (see below) is formed on the recess of the base stop part 22C. Fig. 6 (B)). The first pad 26 is made of an elastic material, such as rubber, etc., and is essentially in the form of a shaft whose axis corresponds to the left and right directions. The first pad 26 is inserted from the left into the mounting hole 22C1, and the left end of the first pad 26 is fitted into the recess of the base stop 22C, thereby fixing the first pad 26 to the base stop 22C. When the first pad 26 is fixed, its left end face protrudes slightly to the left of the base stop 22C. <Hinsichtlich des Griffs 30>

[0023] The handle 30 is designed such that it comprises a main handle body 32 and a secondary handle 34. [Regarding the main handle body 32]

[0024] The main handle body 32 is formed in the form of an essentially cuboid block extending in both forward and backward directions and is arranged in the top view such that it is inclined slightly to the left in the forward direction, as shown in Fig. 2 to Fig. Figure 7(A) shows the rear end section (one end section) of the handle main body 32, which is configured as a handle mounting part 32A, the handle mounting part 32A being formed in a concave shape opening to the right. On the upper wall of the handle mounting part 32A, a main body-side axle part 32B is formed essentially in the form of a cylinder with a base, rising upwards and opening to the right and downwards. The main body-side axle part 32B is connected to the interior of the handle mounting part 32A. Paired main body-side support holes 32C are formed penetrating and coaxially arranged at the top and bottom of the upper wall of the main body-side axle part 32B and the lower wall of the handle mounting part 32A.The handle mounting part 32A is arranged between the lower wall of the base 22 and the support piece 22A, and the lower part of the support axis 24 is inserted into the support holes 32C on the main body. This allows the main handle body 32 to be rotatably mounted on the base 22 via the support axis 24, with the axis direction corresponding to the upward and downward direction.

[0025] The front end (the other end) of the main handle body 32 is designed as a grab handle part 32D. A cutout 32E is formed in the grab handle part 32D, which opens upwards and to the right (towards the outer side in the direction of the vehicle width). The front end section of the grab handle part 32D is cut off in plan view such that it opens forwards and to the right.

[0026] The main handle body 32 is exposed and rotatable from the door trim (interior element) of door D towards the vehicle interior (left side). The main handle body 32 is thus designed so that it is rotated about the support axis 24 by the vehicle occupant grasping the grip section 32D of the main handle body 32 and operating the main handle body 32 to rotate it. Specifically, the grip section 32D of the main handle body 32 is in a pull-operated position (see position according to [reference]). Fig. 9 (B)), into which it is from the neutral position according to Fig. 6 (A) and (B) to one side of the direction of rotation (towards the inside of the vehicle and in the direction closing the door D (in the direction of arrow B in Fig. 6 (B))) is turned, or into a push-operate position (see position according to Fig. 9 (A)), into which it moves from the neutral position to the other side of the direction of rotation (towards the outside of the vehicle and in the direction opening door D (in the direction of arrow A in Fig. 6 (A))) is rotated, designed to be rotatable.

[0027] A right-facing switch operating element 32F, designated as a "main body-side operating element," is formed on the upper wall of the handle mounting part 32A. The front end of the switch operating element 32F is designed as a part for actuating the first switch 44 mentioned later. A main body-side contact element 32G is located on the lower right part of the rear end of the handle main body 32 (see figure). Fig. 6 (B) and Fig. 7 (A)). The main body-side attachment part 32G is designed as a surface that runs along the direction perpendicular to the left and right directions. [Regarding the secondary handle 34]

[0028] As in Fig. 2 to Fig. 6 and Fig. As shown in Figure 7 (B), the secondary handle 34 has an adjacent axial part 34A essentially in the form of a cylinder, the axial direction of which corresponds to the upward and downward direction. A first receiving part 34B, opening to the left, is formed on the lower part of the adjacent axial part 34A, and a second receiving part 34C, opening to the right, is formed on the upper part of the adjacent axial part 34A (see Figure 7 (B)). Fig. 5) A penetrating lateral support hole 34D is formed in each of the upper, lower, and middle walls (wall section between the first receiving part 34B and the second receiving part 34C) of the adjacent axle section 34A. The adjacent axle section 34A, excluding its lower wall, is inserted into the handle mounting part 32A of the handle main body 32, with the support axle 24 simultaneously being inserted into the lateral support holes 34D (see figure). Fig. 5) This allows the secondary handle 34 to be rotatably mounted on the base 22 via the support axis 24. That is, the secondary handle 34 is rotatably mounted coaxially with the main handle body 32 on the base 22. In a state where the secondary handle 34 is mounted on the base 22, the lower wall of the adjacent axis part 34A is positioned between the lower wall of the base 22 and the main handle body 32.

[0029] Furthermore, the secondary handle 34 has a part 34E to be attached, which extends rearward from the adjacent axle part 34A. The part 34E to be attached is inserted into the handle mounting part 32A of the main handle body 32. At the rear end of the part 34E to be attached is a rearward-projecting secondary stop part 34F (see figure). Fig. 4, Fig. 6 (B) and Fig. 7 (B)) is formed, wherein the auxiliary stop part 34F is formed in the form of a plate whose plate thickness direction corresponds to the left and right directions. The auxiliary stop part 34F is arranged adjacent to the right side of the main body-side contact part 32G of the handle main body 32, wherein the main body-side contact part 32G is pressed against the auxiliary stop part 34F by the preload force of the first preload spring 40 mentioned later (see Figure 7 (B)). Fig. 6 (B)).

[0030] Furthermore, a left-facing recess is formed on the left end face of the auxiliary stop part 34F, with a mounting hole 34G penetrating through its bottom surface. A second pad 36 is located on the recess of the auxiliary stop part 34F (see figure). Fig. 4 and Fig. 6 (B)). The second pad 36 is made of an elastic material, such as rubber, etc., and is essentially formed in the shape of a shaft whose axis corresponds to the left and right directions. The left end of the second pad 36 is fitted into the mounting hole 34G, thus fixing the second pad 36 to the auxiliary stop 34F in such a way that it extends to the right from the auxiliary stop 34F. In the fixed state of the second pad 36, the left end face of the second pad 36 projects slightly to the left from the auxiliary stop 34F.

[0031] Furthermore, the secondary handle 34 has a secondary contact element 34H that extends forward from the secondary axle element 34A. The secondary contact element 34H is essentially in the form of a triangular plate, the thickness of which corresponds to the left and right directions. The secondary contact element 34H is arranged between the rear end of the handle part 32D of the main handle body 32 and the base stop element 22C of the base 22. Specifically, the secondary contact element 34H is positioned against the base stop element 22C and simultaneously arranged at a predetermined distance from the rear end of the handle part 32D on its right side (see figure). Fig. 6 (A) and (B)). This causes the rotation of the secondary handle 34 to the other side of the direction of rotation (in the direction of arrow A in Fig. 6 (A)) in plan view limited by base 22.

[0032] Furthermore, the secondary handle 34 has a cam piece 34J that extends to the right from the adjacent axle part 34A. The cam piece 34J is essentially formed in the form of a plate whose thickness direction corresponds to the upward and downward directions. On the upper surface of the cam piece 34J, an upwardly projecting cam part 34K is formed in one piece as an "adjacent operating part". In plan view, the cam part 34K is essentially formed in the form of a fan, the center of which corresponds to the central axis of the adjacent support holes 34D, with the front end of the cam part 34K being formed as a cam surface 34L. At the front end of the cam part 34K, a recess 34M, opening to the right and upwards, is formed on the longitudinally central part of the cam surface 34L. <Hinsichtlich der ersten Vorspannfeder 40>

[0033] The first preload spring 40 is designed as a torsion spring, as in Fig. 4 and Fig. Figure 5 shows the first preload spring 40 being received in the first receiving part 34B of the auxiliary handle 34 and simultaneously inserted into the outer surface of the support axis 24. One end of the first preload spring 40 is engaged on the adjacent contact part 34H of the auxiliary handle 34, and the other end of the first preload spring 40 is engaged on the handle mounting part 32A of the main handle body 32, whereby the first preload spring 40 biases the main handle body 32 towards the side of the pull-operated position (towards one side of the direction of rotation) against the auxiliary handle 34. This causes the main handle body contact part 32G of the main handle body 32 to contact the secondary stop part 34F of the auxiliary handle 34, thereby compressing the second pad 36 through the main handle body contact part 32G. (Regarding the second preload spring 42)

[0034] The second preload spring 42 is a torsion spring, just like the first preload spring 40. The second preload spring 42 is received in the second receiving part 34C of the auxiliary handle 34 and simultaneously inserted into the outer surface of the support axis 24. One end of the second preload spring 42 is engaged with the base 22, and the other end of the second preload spring 42 is engaged with the part 34E of the auxiliary handle 34 to be attached, whereby the second preload spring 42 biases the auxiliary handle 34 towards the side of the push-action position (towards the opposite side of the direction of rotation). This causes the adjacent contact part 34H of the auxiliary handle 34 to press against the base stop part 22C of the base 22, thereby compressing the first pad 26.The state in which the adjacent support part 34H is in contact with the base stop part 22C represents the neutral position of the secondary handle 34, whereby the secondary handle 34 is held in the neutral position by the preload force of the second preload spring 42. In the neutral position of the secondary handle 34, the main handle body 32 is held in the neutral position by the preload force of the first preload spring 40.

[0035] When the main handle body 32 is rotated from the neutral position to the side of the pull-out position, the main-body contact element 32G of the main handle body 32 pushes the secondary stop element 34F of the secondary handle 34 to the right, thus rotating the main handle body 32 and the secondary handle 34 against the preload force of the second preload spring 42 to the side of the pull-out position. That is, when the main handle body 32 is rotated from the neutral position to the side of the pull-out position, the secondary handle 34 is rotated in conjunction with the rotation of the main handle body 32, and the adjacent contact element 34H of the secondary handle 34 is moved to the left away from the base stop element 22C of the base 22. When the operation of the main handle body 32 is released in the pull operating position, the main handle body 32 and the secondary handle 34 return to the neutral position by the preload force of the second preload spring 42.

[0036] In contrast, when the main handle body 32 is rotated from the neutral position to the side of the push-action position, only the main handle body 32 rotates to the side of the push-action position, since the rotation of the secondary handle 34 to the side of the push-action position is limited by the base 22. That is, while maintaining the state in which the secondary handle 34 is in the neutral position, the main-body-side contact part 32G of the main handle body 32 is moved to the left away from the secondary stop part 34F of the secondary handle 34. When the operation of the main handle body 32 is released in the push-action position, the main handle body 32 returns to the neutral position due to the preload force of the first preload spring 40. (Regarding the first switch 44 and second switch 46)

[0037] The first switch 44 and the second switch 46 are designed as lever switches and are electrically connected to the control unit 64 mentioned later, as shown in Fig. 4 and Fig. Figure 8 shows the first switch 44 being located near the lower side of the front end of the switch operating element 32F of the handle body 32. Furthermore, the first switch 44 is positioned such that the axis of rotation of the lever of the first switch 44 corresponds to both left and right. When the handle body 32 is rotated into the push-pull position, the switch operating element 32F is rotated backward to depress the lever of the first switch 44. This actuates the first switch 44, which then sends a detection signal to the control unit 64. In other words, the first switch 44 is designed as a switch for detecting the rotation of the handle 30 into the push-pull position.

[0038] The second switch 46 is located near the right side of the cam section 34K of the auxiliary handle 34. Furthermore, the second switch 46 is positioned such that the axis of rotation of its lever corresponds to the up and down direction. The lever of the second switch 46 is also located in the recess 34M of the cam section 34K. When the main handle body 32 and the auxiliary handle 34 are rotated into the pull-operated position, the cam surface 34L (cam section 34K) of the auxiliary handle 34 is rotated forward to depress the lever of the second switch 46. This actuates the second switch 46, which then sends a detection signal to the control unit 64. In other words, the second switch 46 is designed as a switch for detecting the rotation of the handle 30 into the pull-operated position.

[0039] The first switch 44 and the second switch 46 are mounted on a switch frame 48 fixed to the base 22 (see figure). Fig. 4) attached and at the same time by a switch holder 50 (see Fig. 4) held on the switch frame 48. The switch frame 48 is essentially formed in the form of a T-shaped plate, the thickness of which is oriented in both the left and right directions. The switch frame 48 is located on the right side of the opening 22B of the base 22 and is fixed to the base 22 by fixing elements such as screws, etc. The switch holder 50 is essentially formed in the form of a rectangular frame board, the thickness of which is oriented in both the left and right directions, and is located adjacent to the left side of the switch frame 48. The switch holder 50 is fixed to the switch frame 48 by fixing elements such as screws, etc. <Hinsichtlich der Knopfabdeckung 52>

[0040] The button cover 52 is arranged on the upper side of the handle mounting part 32A of the handle main body 32 and is designed as a component for covering the upper part of the support axis 24, as shown in Fig. 2 to Fig. Figure 5 shows the knob cover 52. The knob cover 52 has a cover axle part 52A, which is essentially in the form of a cylinder whose axis direction corresponds to the upward and downward direction. The cover axle part 52A is arranged between the upper wall of the base 22 and the support piece 22A and is supported by the support axle 24. The knob cover 52 has a cover part 52B. The cover part 52B extends downward from the cover axle part 52A and is formed such that it covers the left side of the main body-side axle part 32B of the handle main body 32.

[0041] The door opening and closing drive unit 60 is designed as a drive unit for opening and closing the door D by controlling the control unit 64 mentioned later, as shown in Fig. Figure 1 shows the door opening and closing drive unit 60, which, as an example, has a motor as its drive source and transmits the motor's drive to a door hinge provided on the door D in order to rotate the door hinge and thus open and close the door D. A coupling mechanism or gear mechanism, for example, can be used to transmit the drive from the motor to the door hinge. (Door opening and closing position detection device 62)

[0042] The door opening and closing position detection device 62 is designed as a device for detecting the opening and closing position of the door D. The door opening and closing position detection device 62 is designed, for example, as an encoder, etc., and is arranged near the door hinge to detect the degree of opening of the door hinge. The door opening and closing position detection device 62 is electrically connected to the control unit 64 mentioned later and outputs a detection signal to the control unit 64 corresponding to the opening and closing position of the door D. The door opening and closing position detection device 62 is not limited to the structure described above.For example, a sensor for detecting the rotational position of the motor's output shaft on the door opening and closing drive part 60 can be designed as the door opening and closing position detection device 62 to detect the opening and closing position of the door D. (Regarding the control part 64)

[0043] The control unit 64 is electrically connected to the first switch 44 and second switch 46 of the aforementioned device 20 for detecting the door opening and closing, the door opening and closing drive unit 60, and the door opening and closing position detection device 62. The control unit 64 assesses both the rotational operating state of the handle 30 based on the detection signals from the first switch 44 and second switch 46, and the opening and closing position (state) of the door D based on the detection signal from the door opening and closing position detection device 62. The control unit 64 is designed such that, based on the assessed rotational operating state of the handle 30 and the opening and closing position of the door D, it controls the drive of the door opening and closing drive unit 60. (Effects and Effects)

[0044] The effects and impacts of the present embodiment are then described, explaining the operation of the device 20 for detecting the door opening and closing, as well as the operation of the door opening and closing device. (Regarding the operation of device 20 for detecting door opening and closing)

[0045] In a non-actuated state of the device 20 for detecting the door opening and closing, the handle 30 (the main handle body 32 and the secondary handle 34) is arranged in the neutral position, as shown in Fig. 6 (A) and (B) shown. If the grab handle part 32D of the main handle body 32 is grasped by a vehicle occupant in this state and subjected to a push operation towards the outside of the vehicle, the main handle body 32 is moved from the neutral position to the side of the push operation position (in the direction of arrow A) against the preload force of the first preload spring 40. Fig. 6 (A) and to the other side of the direction of rotation) about the support axis 24. In contrast, the adjacent contact part 34H of the secondary handle 34 is contacted against the base stop part 22C of the base 22, thus limiting the rotation of the secondary handle 34 to the side of the push-action position. Therefore, when the main handle body 32 is pushed, the main handle body 32 alone is rotated from the neutral position to the side of the push-action position, while the neutral position of the secondary handle 34 is maintained, as shown in Fig. 9 (A) shown. That is, the main body-side attachment part 32G of the main handle body 32 is moved to the left by the secondary stop part 34F of the secondary handle 34.

[0046] When the main handle body 32 reaches the push-action position, the switch operating part 32F of the main handle body 32 presses the lever of the first switch 44, thereby actuating the first switch 44. This causes the first switch 44 to send a detection signal to the control unit 64. When the main handle body 32 rotates into the push-action position, the second switch 46 is not actuated because the neutral position of the secondary handle 34 is maintained, as mentioned above.

[0047] When the operation of the main handle body 32 is released in the push-action position, the main handle body 32 is rotated from the push-action position to the neutral position by the preload force of the first preload spring 40. Then the main-body-side contact part 32G of the main handle body 32 is contacted with the secondary stop part 34F of the secondary handle 34, whereby the main handle body 32 returns to the neutral position.

[0048] If, on the other hand, the handle part 32D of the handle main body 32 is grasped by the vehicle occupant and subjected to a pulling operation towards the vehicle interior, the handle main body 32 is moved from the neutral position to the side of the pulling operation position (in the direction of arrow B in Fig. 6 (B) and to one side of the direction of rotation) about the support axis 24. The main body-side contact part 32G of the main handle body 32 is in contact with the secondary stop part 34F of the secondary handle 34, so that the main body-side contact part 32G pushes the secondary stop part 34F to the right. This causes the main handle body 32 and the secondary handle 34 to rotate from the neutral position to the side of the pull-operate position, against the preload force of the second preload spring 42, as shown in Fig. Figure 9 (B) shows the auxiliary handle 34H being moved to the left away from the base stop 22C of the base 22. In other words, the auxiliary handle 34 is rotated from the neutral position to the side of the pull-out position in conjunction with the rotation of the main handle body 32 to the side of the pull-out position.

[0049] When the main handle body 32 and the secondary handle 34 reach the pull-operated position, the cam surface 34L of the cam part 34K of the secondary handle 34 presses the lever of the second switch 46, thereby actuating the second switch 46. This causes the second switch 46 to send a detection signal to the control unit 64. When the main handle body 32 rotates into the pull-operated position, the first switch 44 is not actuated because the switch operating part 32F of the main handle body 32 rotates forward (in the direction away from the first switch 44).

[0050] When the operation of the main handle body 32 is released in the pull-operated position, the main handle body 32 and the secondary handle 34 are rotated from the pull-operated position to the neutral position side by the preload force of the second preload spring 42. Then, the adjacent contact part 34H of the secondary handle 34 is pressed against the base stop part 22C of the base 22, causing the main handle body 32 and the secondary handle 34 to return to the neutral position. (Regarding the operation of the door opening and closing device when performing the pull operation of the handle 30 in a state in which the door D is arranged in the fully closed position)

[0051] In a state where door D is in the fully closed position, closing the door opening section of the vehicle V, the control unit 64 detects, based on the signal output of the door opening and closing position detection device 62, that door D is in a fully closed state. If, in this state, a vehicle occupant rotates the handle 32 and the secondary handle 34 into the pull-operated position by pulling the handle part 32D of the handle main body 32 of the door opening and closing detection device 20, the control unit 64 detects the rotation of the handle 30 into the pull-operated position based on the detection signal from the second switch 46.

[0052] When the control unit 64 detects the rotation of the handle 30 into the pull-operate position, the control unit 64 drives the door opening and closing drive unit 60 such that the door D is rotated from the fully closed position in the opening direction. This rotates the door D from the fully closed position to the side of the fully open position, thereby opening the door opening section of the vehicle V. (Regarding the operation of the door opening and closing device when performing the push operation of the handle 30 in a state in which the door D is arranged in the fully closed position)

[0053] In a state where door D is in the fully closed position, the control unit 64, as described above, detects that door D is in a fully closed state based on the signal output of the door opening and closing position detection device 62. If, in this state, the handle body 32 is rotated into the push-pull position by the vehicle occupant of the door opening and closing detection device 20 by pushing the handle part 32D of the handle body 32 into the push-pull position, the control unit 64 detects the rotation of the handle 30 into the push-pull position based on the detection signal from the first switch 44.

[0054] When the control unit 64 detects the rotation of the handle 30 into the push-to-open position, the control unit 64 inhibits the drive of the door opening and closing drive unit 60. That is, the control unit 64 does not drive the door opening and closing drive unit 60. This prevents the door D from rotating from the fully closed position in the opening direction, thus maintaining the fully closed state of the door D. (Regarding the operation of the door opening and closing device when performing the pull operation of the handle 30 in a state in which the door D is in the fully open position or in the open position)

[0055] In a state where door D is rotated from the fully closed position to the fully open position, the control unit 64 detects, based on the signal output of the door opening and closing position detection device 62, that door D is in the fully open position or in the open position. The open position of door D is a position between the fully closed position and the fully open position of door D. If, in this state, the vehicle occupant pulls the handle part 32D of the handle main body 32 of the door opening and closing detection device 20, rotating the handle main body 32 and the secondary handle 34 into the pull-operate position, the control unit 64 detects the rotation of the handle 30 into the pull-operate position based on the detection signal from the second switch 46.

[0056] When the control unit 64 detects the rotation of the handle 30 into the pull-operate position, the control unit 64 drives the door opening and closing drive unit 60 such that the door D is rotated from the fully open position or the open position in the closing direction. This rotates the door D from the fully open position or the open position to the fully closed position, thereby closing the door opening section of the vehicle V. (Regarding the operation of the door opening and closing device when performing the push operation of the handle 30 in a state in which the door D is arranged in the open position)

[0057] In a state where door D is in the open position, the control unit 64 detects that door D is in the open position based on the signal output of the door opening and closing position detection device 62. If, in this state, the handle body 32 is rotated into the push-pull position by the vehicle occupant of the door opening and closing detection device 20 by pushing the handle part 32D of the handle main body 32 into the push-pull position, the control unit 64 detects the rotation of the handle 30 into the push-pull position based on the detection signal from the first switch 44.

[0058] When the control unit 64 detects the rotation of the handle 30 into the push-to-open position, the control unit 64 drives the door opening and closing drive unit 60 such that the door D is rotated from the open position in the opening direction. This rotates the door D into the fully open position, thereby increasing the degree of opening of the door D.

[0059] As explained above, the handle 30 of the device 20 for detecting the door opening and closing is rotatably mounted on the base 22 according to the present embodiment, with the axis direction of the handle 30 corresponding to the upward and downward direction. The front end part of the handle 30 is designed as a grip section 32D, which is exposed and operable from the door D towards the interior of the vehicle. When the grip section 32D of the handle 30 is rotated into the push-action position, into which it is rotated from the neutral position towards the exterior of the vehicle (in the opening direction of the door D), the first switch 44 is actuated by the switch operating part 32F of the handle 30.In contrast, when the handle part 32D of the handle 30 is rotated into the pull-operate position, to which it is turned from the neutral position towards the interior of the vehicle (in the closing direction of door D), the second switch 46 is actuated by the cam surface 34L (cam part 34K) of the handle 30. This allows the operation of the handle 30 to be detected by matching the direction of the push and pull operation of the handle part 32D of the handle 30 with the opening and closing direction of door D. In particular, the operation of the handle 30 when pulled from the neutral position corresponds to the operation of the manual interior handle located on the side door of a conventional vehicle. Therefore, the vehicle occupant can intuitively recognize the operation of the handle 30 when opening and closing door D. Thus, the ease of use of the handle 30 for the vehicle occupant is increased.

[0060] In the device 20 for detecting the opening and closing of the door, the handle 30 is designed such that it comprises the main handle body 32 with the retaining handle part 32D and the secondary handle 34. When the main handle body 32 is rotated from the neutral position to the side of the pull-operated position (towards one side of the direction of rotation), the secondary handle 34 is rotated in conjunction with the main handle body 32. Furthermore, when the main handle body 32 is rotated from the neutral position to the side of the push-operated position (towards the other side of the direction of rotation), the secondary handle 34 is engaged independently of the rotation of the main handle body 32 and held in the neutral position. This allows the second switch 46 to be actuated by the cam part 34K of the secondary handle 34 when the main handle body 32 is pulled, and the first switch 44 to be actuated by the switch operating part 32F of the main handle body 32 when the main handle body 32 is pushed.

[0061] In the device 20 for detecting the opening and closing of the door, the first preload spring 40 biases the main handle body 32 towards the pull-operate side (towards one side of the direction of rotation) against the secondary handle 34, and the second preload spring 42 biases the secondary handle 34 towards the push-operate side (towards the other side of the direction of rotation) against the base 22. Furthermore, in the neutral position of the handle 30, the adjacent contact part 34H of the secondary handle 34 is pressed against the base stop part 22C of the base 22, thereby limiting the rotation of the secondary handle 34 towards the push-operate side (towards the other side of the direction of rotation).In the neutral position of the handle 30, the main body-side contact element 32G of the main handle body 32 is also pressed against the secondary stop element 34F of the secondary handle 34, thereby limiting the rotation of the main handle body 32 towards the pull-operate side (towards one side of the direction of rotation). Therefore, when the main handle body 32 is rotated from the neutral position to the pull-operate side, the secondary handle 34 can be rotated in conjunction with the main handle body 32. Furthermore, when the main handle body 32 is rotated from the neutral position to the push-operate side, the secondary handle 34 can be held in the neutral position independently of the rotation of the main handle body 32.

[0062] In the door opening and closing device, the control unit 64 drives the door opening and closing drive unit 60 and rotates the door D in the opening direction when the handle 30 is turned to the pull-operate position while the door D is in the fully closed position. This ensures that the operation of the handle 30 when opening the door D is identical to the operation of the manual interior handle located on the side door of a conventional vehicle (motor vehicle). Therefore, ease of use for the vehicle occupant can be further improved.

[0063] In the door opening and closing device, the control unit 64 inhibits the drive of the door opening and closing drive unit 60 when the handle 30 is turned to the push-to-operate position while the door D is in the fully closed position. Therefore, for example, opening the door D, which is in the fully closed position, can be prevented even if the vehicle occupant unintentionally presses the retaining grip part 32D of the handle 30. This increases the safety of the vehicle occupant.

[0064] In the door opening and closing device, the control unit 64 drives the door opening and closing drive unit 60 and rotates the door D in the closing direction when the handle 30 is turned to the pull-operate position while the door D is in the fully open or partially open position. This allows the direction for closing the door D to coincide with the direction for operating the handle 30 when the door D is closed while in the fully open or partially open position. Therefore, ease of use for the vehicle occupant can be effectively improved.

[0065] In the door opening and closing device, the control unit 64 drives the door opening and closing drive unit 60 and rotates the door D in the opening direction when the handle 30 is turned to the push-to-operate position while the door D is in the open position. This allows the direction for opening the door D to coincide with the direction for operating the handle 30 when the door D is opened further while in the open position. Therefore, as described above, ease of use for the vehicle occupant can be effectively improved.

[0066] In the device 20 for detecting the opening and closing of the door according to the present embodiment, the handle mounting part 32A of the handle main body 32 is supported on the support axis 24, and the retaining handle part 32D of the handle main body 32 extends forward from the handle mounting part 32A. Alternatively, the retaining handle part 32D of the handle main body 32 can be configured in reverse in the device 20 for detecting the opening and closing of the door, in both the forward and reverse directions. Alternatively, the retaining handle part 32D of the handle main body 32, which is configured in reverse in both the forward and reverse directions, can be further configured such that it is arranged rotated by 180° on a plane running in both upward and downward directions as well as forward and backward directions.

[0067] In this case, the secondary handle 34 is designed such that, when the handle part 32D of the main handle body 32 is rotated from the neutral position to the push-action position, it rotates in conjunction with the main handle body 32. Furthermore, the secondary handle 34 is designed such that, when the handle part 32D of the main handle body 32 is rotated from the neutral position to the pull-action position, it remains in the neutral position independently of the rotation of the main handle body 32. That is, the direction of rotation of the main handle body 32 from the neutral position to the push-action position corresponds to one side of the direction of rotation according to the present invention, and the direction of rotation of the main handle body 32 from the neutral position to the pull-action position corresponds to the other side of the direction of rotation according to the present invention.

[0068] In this case, the structure is designed such that the positions of the first switch 44 and the second switch 46 are reversed. That is, the structure is designed such that when the main handle body 32 is rotated from the neutral position to the push-action position, the first switch 44 is actuated by the cam part 34K of the secondary handle 34, and when the main handle body 32 is rotated from the neutral position to the pull-action position, the second switch 46 is actuated by the switch operating part 32F of the main handle body 32.

[0069] In the device 20 for detecting the door opening and closing according to the present embodiment, the push-operate position of the handle 30 is detected by the first switch 44 and the pull-operate position of the handle 30 is detected by the second switch 46, but the detection of the operating position of the handle 30 is not limited to this structure. Variant examples of the device 20 for detecting the door opening and closing are explained below. (Variant example 1 of the device for detecting door opening and closing)

[0070] In variant example 1, the secondary handle 34 and the second preload spring 42 on the handle 30 are omitted, so that the handle 30 is formed only from the main handle body 32, as in Fig. Figure 10 (A) shows the following: On the main handle body 32, the switch operating element 32F projects to the right of the support axis 24. A groove 32F1, opening to the right, is formed at the front end of the switch operating element 32F. This creates a front and a rear operating element 32F2 as a pair at the front end of the switch operating element 32F, with the paired operating elements 32F2 being arranged opposite each other in the forward and reverse directions via the groove 32F1.

[0071] In variant example 1, a neutral spring (not shown), which is formed from a torsion spring, etc., is provided instead of the first preload spring 40, by which the handle main body 32 is held in the neutral position. The handle main body 32 is designed such that it returns to the neutral position by the preload force of the neutral spring when it is rotated into the push or pull operating position.

[0072] In variant example 1, a switch 70 is also provided as a "detection element" instead of the first switch 44 and second switch 46. The switch 70 is attached to the base 22 (not shown) via a switch holder, etc. (not shown in Fig. 10 (A)) is fixed and simultaneously electrically connected to the control unit 64. The switch 70 is designed as a detector switch with a lever 70A, which is operable in two directions. Specifically, the lever 70A is arranged between the paired operating elements 32F2 of the switch operating unit 32F.

[0073] When the handle section 32D of the handle body 32 is rotated from the neutral position to the push-to-operate position, the lever 70A is pressed by the front control element 32F2 of the switch control element 32F, thereby actuating the switch 70. Conversely, when the handle section 32D of the handle body 32 is rotated from the neutral position to the pull-to-operate position, the lever 70A is pressed by the rear control element 32F2 of the switch control element 32F, thereby actuating the switch 70. In variant example 1, this also allows the operation of the handle 30 to be controlled by matching the direction of push or pull operation of the handle section 32D of the handle 30 (handle body 32) with the opening and closing direction of the door D. Therefore, the ease of use of the handle 30 for the vehicle occupant can also be improved in variant example 1. (Variant example 2 of the device for detecting door opening and closing)

[0074] In variant example 2, as in variant example 1, the secondary handle 34 and the second preload spring 42 on the handle 30 are omitted, so that the handle 30 consists only of the main handle body 32, as in Fig. Figure 10 (B) shows the switch control element 32F projecting to the right of the main handle body 32 on the right side of the support axis 24. A magnet 80 is provided at the front end of the switch control element 32F. In variant example 2, a neutral spring is also provided on the main handle body 32, which holds the main handle body 32 in the neutral position, just as in variant example 1. In variant example 2, a pair of magnetic sensors 82, 84 is also used as

[0075] A "detection element" is provided in place of the first switch 44 and second switch 46. The magnetic sensors 82, 84 are designed as Hall elements and are mounted on the base 22 (not shown) via a sensor substrate (not shown). Fig. 10 (B)) is fixed and simultaneously electrically connected to the control unit 64. The magnetic sensor 82 is arranged on the rear side of the magnet 80, and the magnetic sensor 84 is arranged on the front side of the magnet 80. The magnetic sensors 82 and 84 output detection signals to the control unit 64 according to the magnetic flux density of the magnet 80, thereby enabling the control unit 64 to detect the position of the handle 30.

[0076] When the handle section 32D of the handle body 32 is rotated from the neutral position to the push-to-operate position, the magnet 80 is brought close to the magnetic sensor 82, which detects the push-to-operate position of the handle body 32. Conversely, when the handle section 32D of the handle body 32 is rotated from the neutral position to the pull-to-operate position, the magnet 80 is brought close to the magnetic sensor 84, which detects the pull-to-operate position of the handle body 32. In variant example 2, this also allows the operation of the handle 30 to be detected by matching the direction of push or pull operation of the handle section 32D of the handle 30 (handle body 32) with the opening and closing direction of the door D. Therefore, the ease of use of the handle 30 for the vehicle occupant can also be improved in variant example 2.
