Detailed Implementation
[0054] <First Implementation Method>
[0055] The following is for reference Figures 1-3 The opening and closing body control device 100 of the first embodiment of the present invention will be described.
[0056] like Figure 1As shown, the opening and closing body control device 100 has a driving device 1, an opening and closing device 7, and a suction device 8. The opening and closing device 7 is provided on a door of a vehicle, and can perform an opening action or a closing action to open or close the door relative to a vehicle body. Here, the vehicle is an example of a moving body, the vehicle body is an example of a main body, and the door is an example of an opening and closing body. The suction device 8 is provided on the door, and can perform a suction action or a release action to suction the door to the vehicle body or release the suction of the door relative to the vehicle body. The driving device 1 is provided on the door, and is connected to the opening and closing device 7 and the suction device 8 to drive the opening and closing device 7 and the suction device 8 to act.
[0057] The opening and closing device 7 includes a push rod 71 and a push block 72. One end of the push rod 71 is hingedly connected to the vehicle body. The push block 72 is fixed to the push rod 71, and is connected to the driving device 1 via a pull wire C1, although the specific connection is not shown in the figure. The connection of the push block 72 to the pull wire C1 can be made in any known manner, as long as the push block 72 can receive the force applied by the pull wire C1. When the driving device 1 is operated, a driving force is applied to the push block 72 from the driving device 1 via the pull wire C1. At this time, the push block 72 is subjected to a force toward or away from the vehicle body, and this force is applied to the push rod 71 to act on the vehicle body, so that the door is opened or closed by the reaction force of the vehicle body.
[0058] The driving device 1 has a lead screw 20, a nut block 30, a suction block 40, a first locking mechanism 50, a second locking mechanism 60, a housing 15, and a driving motor 10. The housing 15 houses the lead screw 20, the nut block 30, the suction block 40, the first locking mechanism 50, and the second locking mechanism 60. The driving motor 10 is an example of a power source.
[0059] The lead screw 20 is fixedly connected to the output shaft of the driving motor 10, and the axis of the lead screw 20 is on the same line as the axis of the output shaft of the driving motor 10. When the driving motor 10 is actuated (rotates in the forward or reverse direction), the lead screw 20 rotates using the driving force transmitted from the driving motor 10.
[0060] The nut block 30 is provided on the lead screw 20, and a helical line is provided in the nut block 30 to form a nut-screw pair with the lead screw 20. When the lead screw 20 rotates, the nut block 30 moves along the lead screw 20 in a reciprocating linear motion. The nut block 30 has a sliding portion 31 that moves along the lead screw 20, a first protruding portion 32 that protrudes from the sliding portion 31 toward the first locking mechanism 50 for engagement or disengagement of a first pawl 51 described later, and a second protruding portion 33 that protrudes from the sliding portion 31 toward the second locking mechanism 60 for engagement or disengagement of a second pawl 61 described later.
[0061] The suction slider 40 is connected to the suction device 8 through the pull wire C2, and the suction device 8 is driven to perform the suction operation or the release operation by the movement of the suction slider 40. The suction device 8 can adopt any known structure such as an automatic suction lock.
[0062] The first locking mechanism 50 has a first pawl 51, a first guide rail 52, and a first connecting member 53. The first locking mechanism 50 is connected to the opening and closing device 7, and specifically, the first connecting member 53 is connected to the push block 72 of the opening and closing device 7 through the pull wire C1. Moreover, the first pawl 51 is rotatably connected to the first connecting member 53 through a first connecting shaft 54, in other words, the first pawl 51 can rotate around the first connecting shaft 54. Thus, the first pawl 51 can slide along the first guide rail 52 rotatably.
[0063] The second locking mechanism 60 has a second pawl 61, a second guide rail 62, and a second connecting member 63. The second connecting member 63 abuts against the suction slider 40. The second pawl 61 is rotatably connected to the second connecting member 63 through a second connecting shaft 64, in other words, the second pawl 61 can rotate around the second connecting shaft 64. Thus, the second pawl 61 can slide along the second guide rail 62 rotatably. When the second pawl 61 slides, the second locking mechanism 60 pushes the suction slider 40 to move together.
[0064] In other words, the driving device 1 is connected to both the opening and closing device 7 and the suction device 8, and the opening and closing device 7 and the suction device 8 are driven to operate by the same driving motor 10. Specifically, the driving device 1 sequentially performs the release operation of the suction device 8 and the opening operation of the opening and closing device 7, or sequentially performs the closing operation of the opening and closing device 7 and the suction operation of the suction device 8, by using the driving force transmitted from the driving motor 10.
[0065] Since the opening and closing body control device 100 having the above structure can drive the opening and closing device 7 and the suction device 8 to perform the opening and closing operation and the suction operation of the opening and closing body by the same driving motor 10, the opening and closing body control device 100 only needs to be provided with one driving motor 10. Compared with the opening and closing body control device using the opening and closing device with a built-in motor and the suction device with a built-in motor, the opening and closing body control device can be miniaturized as a whole, and the cost of parts can be reduced, and thus the total cost of the opening and closing body control device can be reduced.
[0066] Hereinafter, the operation of the opening and closing body control device 100 will be described in detail with reference to the accompanying drawings. Figures 1-3 The operation of the opening and closing body control device 100 will be described in detail. Figure 1 , Figure 2 , Figure 3 The opening and closing body control device 100 in the state that the vehicle door is in the open state (maximum opening degree), the state that the vehicle door is in the closed state and is not suctioned to the vehicle body, and the state that the vehicle door is in the closed state and is suctioned to the vehicle body, respectively.
[0067] like Figures 1-3 As shown, the nut slider 30 can move along the lead screw 20 between the first position P1, the second position P2, and the third position P3.
[0068] First, such as Figure 1 As shown, when the car door is in its fully open state, the nut slider 30 is located in the first position P1. At this time, the first pawl 51 in the first locking mechanism 50 engages with the first protrusion 32 of the nut slider 30, and the first pawl 51 is at one end of its stroke on the first guide rail 52. The second pawl 61 in the second locking mechanism 60 does not engage with the second protrusion 33 of the nut slider 30, and the second pawl 61 is at one end of its stroke.
[0069] Then, to close the door, the opening / closing control device 100 rotates the drive motor 10 in the forward direction. Due to the driving force transmitted from the drive motor 10 to the lead screw 20, the nut slider 30 moves along the first guide rail 52 from the first position P1 to the second position P2. During this period, the first pawl 51 remains engaged with the first protrusion 32 of the nut slider 30. Because the first pawl 51 remains engaged with the first protrusion 32 during this period, the first pawl 51 slides on the first guide rail 52 as the nut slider 30 moves, thereby applying force to the push block 72 of the opening / closing device 7 via the pull cable C1. In this way, the driving force of the drive motor 10 is transmitted to the opening / closing device 7, and the opening / closing device 7 performs a closing action to change the door from the open state to the closed state. Figure 2 As shown, when the nut slider 30 is in the second position P2, the first pawl 51 is at the other end of its stroke. At this time, the second pawl 61 is still at one end of its stroke.
[0070] After the car door is closed, in order to magnetically attach the door to the car body, the opening / closing control device 100 continues to rotate the drive motor 10 in the forward direction, and the nut slider 30 moves further from the second position P2 to the third position P3. During this period, since the first pawl 51 was already at the other end of its stroke in the second position P2, the first pawl 51 cannot advance further with the nut slider 30. Therefore, as the nut slider 30 moves further, the first pawl 51 rotates around the first connecting shaft 54, and the first protrusion 32 of the nut slider 30 begins to disengage from the first pawl 51. On the other hand, the second pawl 61 begins to engage with the second protrusion 33 of the nut slider 30 and begins to move from one end of its stroke. The second pawl 61 abuts against the suction slider 40, pushing the suction slider 40 to begin sliding together. Therefore, when the second pawl 61 engages with the second protrusion 33, the driving force from the drive motor 10 is transmitted to the suction device 8 via the suction slider 40 and the pull cable C2. The suction device 8 performs a suction action, magnetically attaching the car door to the car body. Figure 3As shown, when the nut slider 30 is located at the third position P3, the first pawl 51 is still not engaged with the nut slider 30 and is at the other terminal of the stroke of the first pawl 51, and the second pawl 61 is engaged with the second protruding portion 33 of the nut slider 30 and is at the other terminal of the stroke of the second pawl 61.
[0071] When the driving motor 10 reversely rotates, the nut slider 30 moves from the third position P3 to the second position P2 and the first position PI. During this period, the suction slider 40 returns due to the elastic force of the unillustrated spring, the suction device 8 performs the un-suction operation, and when the nut slider 30 reaches the second position P2, the first protruding portion 32 and the first pawl 51 re-start engaging, the driving force of the driving motor 10 is transmitted to the opening and closing device 7 via the first locking mechanism 50 again, and the opening and closing device 7 performs the opening operation, so that the door changes from the closed state to the opened state.
[0072] According to the driving device 1 as described above, the opening and closing of the door and the suction / un-suction can be realized by using the same driving motor 10. Also, the opening and closing body control device 100 having such a driving device 1 can realize the transmission of the driving force to the opening and closing device 7 and the suction device 8 by a simple structure, so that the opening and closing device 7 and the suction device 8 sequentially perform the closing operation and the suction operation, or sequentially perform the un-suction operation and the opening operation.
[0073] <Second Embodiment>
[0074] Reference Figure 4 The opening and closing body control device 200 of the second embodiment will be described. Hereinafter, mainly the difference between the second embodiment and the first embodiment will be described, and the same symbols will be attached to the same parts as those of the first embodiment and the description thereof will be omitted.
[0075] The opening and closing body control device 200 has a gear transmission portion 90 provided at one axial end portion of the screw rod 20 and fixedly connected to the output shaft of the driving motor 10. When the output shaft of the driving motor 10 rotates, the driving force is transmitted to the screw rod 20 via the gear transmission portion 90.
[0076] In the second embodiment, the driving motor 10 is arranged so that the output shaft thereof is parallel to the output shaft of the screw rod 20. Specifically, the driving motor 10 and the suction slider 40 are arranged on the same side of the screw rod 20 in the up-down direction of the vehicle, for example, on the lower side of the screw rod 20.
[0077] The remaining portions of the opening and closing body control device 200 are the same as those of the opening and closing body control device 100. Thus, in addition to being able to function and effect the same as the first embodiment, the degree of freedom of arrangement of the driving motor 10 can be improved. Also, the space on the lower side of the screw rod 20 can be sufficiently utilized, so that the opening and closing body control device 200 can be arranged more compactly.
[0078] <Third Embodiment>
[0079] Reference Figure 5 The opening and closing body control device 300 of the third embodiment will be described. Hereinafter, the differences between the third embodiment and the second embodiment will be mainly described, and the same symbols will be assigned to the same parts as those of the second embodiment and the description thereof will be omitted.
[0080] In the third embodiment, the opening and closing device 7A is used instead of the opening and closing device 7. The opening and closing device 7A does not have a push block. One end of the push rod 71 is hinged to the vehicle body and the other end is directly fixed to the first connecting member 53 of the first locking mechanism 50. The remaining parts of the opening and closing body control device 300 are the same as those of the opening and closing body control device 200.
[0081] By so doing, in addition to being able to achieve the same effects as those of the first and second embodiments, the pull wire can be omitted, the opening and closing body control device can be made more compact, and the cost can be further reduced.
[0082] <Fourth Embodiment>
[0083] Reference Figure 6 The opening and closing body control device 400 of the fourth embodiment will be described. Hereinafter, the differences between the fourth embodiment and the third embodiment will be mainly described, and the same symbols will be assigned to the same parts as those of the third embodiment and the description thereof will be omitted.
[0084] The main difference between the fourth embodiment and the third embodiment is that the opening and closing device 7B is used instead of the opening and closing device 7A. In the opening and closing device 7A, the push rod 71 is located outside the housing 15 as a whole, whereas in the opening and closing device 7B, a part of the push rod 71 away from the vehicle body protrudes into the inside of the housing 15. The remaining parts of the opening and closing body control device 400 are the same as those of the opening and closing body control device 300.
[0085] By so doing, in addition to being able to achieve the same effects as those of the third embodiment, the occupied space of the opening and closing device can be further saved, and the opening and closing body control device 400 as a whole can be further compactified and downsized.
[0086] <Fifth Embodiment>
[0087] Reference Figure 7 The opening and closing body control device 500 of the fifth embodiment will be described.
[0088] The fifth embodiment differs from the fourth embodiment in that, in the opening / closing body control device 500, the drive motor 10 and the suction slider 40 are disposed on different sides of the screw rod 20 in the up-down direction of the vehicle. For example, the suction slider 40 is disposed on the lower side of the screw rod 20, and the drive motor 10 is disposed on the upper side of the screw rod 20. The remaining parts of the opening / closing body control device 500 are the same as those of the opening / closing body control device 400.
[0089] By so doing, in addition to being able to function and effect the same as the fourth embodiment, since a plurality of components are mounted on the vehicle door, in the case where other components are arranged below the drive device 1, it is possible to avoid interference between the drive motor and them, and to avoid affecting the operation of the other components.
[0090] <Sixth Embodiment>
[0091] Reference Figure 8 The opening / closing body control device 600 of the sixth embodiment will be described. Hereinafter, mainly the differences between the sixth embodiment and the second embodiment will be described, and the same parts as those of the second embodiment will be denoted by the same reference numerals and will not be described.
[0092] The main difference between the sixth embodiment and the second embodiment is that the drive device 1 is replaced by the drive device 1A.
[0093] In the drive device 1A, the screw rod includes a first screw rod 21 and a second screw rod 22, the axes of the first screw rod 21 and the second screw rod 22 are parallel to each other, and the length and the thread pitch of the second screw rod 22 are different from those of the first screw rod 21. In addition, the gear transmission portion includes a first gear transmission portion 91 provided at one axial end of the first screw rod 21 and the second screw rod 22, and a second gear transmission portion 92 provided at the other axial end of the first screw rod 21 and the second screw rod 22. In addition, the nut slider includes a first nut slider 30A provided at the first screw rod 21 and a second nut slider 30B provided at the second screw rod 22. The first nut slider 30A is engageable with the first lock mechanism 50, and the second nut slider 30B is engageable with the second lock mechanism 60.
[0094] The output shaft of the drive motor 10 is connected to the first gear transmission portion 91, the driving force of the drive motor 10 is transmitted to the first screw rod 21 via the first gear transmission portion 91 to rotate the first screw rod 21, the driving force is transmitted to the second gear transmission portion 92, and the second gear transmission portion 92 transmits the driving force to the second screw rod 22 to rotate the second screw rod 22.
[0095] The operation of the drive device 1A is the same as that of the drive device 1, and a detailed description thereof is omitted. Since the length and the thread pitch of the second screw rod 22 are set to be different from those of the first screw rod 21, the engagement of the first nut slider 30A with the first locking mechanism 50 and the engagement of the second nut slider 30B with the second locking mechanism 60 occur at different times. Thus, the vehicle door can sequentially perform the opening operation, the latching operation, and sequentially perform the unlatching operation and the closing operation. The remaining portions of the opening / closing body control device 600 are the same as those of the opening / closing body control device 200. In this way, the same effects as those of the second embodiment can be achieved by using a double screw rod structure.
[0096] <Seventh Embodiment>
[0097] Reference Figure 9 The opening / closing body control device 700 of the seventh embodiment will be described. Hereinafter, mainly the differences between the seventh embodiment and the first embodiment will be described, and the same reference numerals are assigned to the same portions as those of the first embodiment and a description thereof is omitted.
[0098] The main difference between the seventh embodiment and the first embodiment is that the drive device 1 is replaced by the drive device 1B.
[0099] The drive device 1B has a screw rod 20, a nut slider 30A', a transmission slider 30B', a latching slider 40', a locking mechanism 50', a transmission arm 35, a housing 15, and a drive motor 10. The drive motor 10, the screw rod 20, and the like are the same as those of the first embodiment. In addition, the locking mechanism 50' is the same as the first locking mechanism 50 of the sixth embodiment, and the nut slider 30A' is the same as the first nut slider 30A of the sixth embodiment, and thus a description of these components is appropriately omitted.
[0100] The nut slider 30A' is provided to the screw rod 20. When the drive motor 10 drives the screw rod 20 to rotate, the nut slider 30A' performs a reciprocating linear motion along the screw rod 20.
[0101] The locking mechanism 50' is connected to the opening / closing device 7 and can be engaged with the nut slider 30A'. The engagement is substantially the same as that between the first locking mechanism 50 of the sixth embodiment and the first nut slider 30A. During the engagement of the locking mechanism 50' with the nut slider 30A', the driving force of the drive motor 10 is transmitted to the push rod 71 of the opening / closing device 7. During this period, when the drive motor 10 rotates in the forward direction, the opening / closing device 7 performs a closing operation to change the vehicle door from the open state to the closed state. When the drive motor 10 rotates in the reverse direction, the opening / closing device 7 performs an opening operation to change the vehicle door from the closed state to the open state.
[0102] The transmission slider 30B' is not provided with a helical line, and is fitted to the screw rod 20 in a freely slidable manner. When the drive motor 10 is rotated in the forward direction, the screw rod 20 is rotated, and the nut slider 30A' moves toward the transmission slider 30B'. Due to the forward rotation of the drive motor 10, the lock mechanism 50' moves together with the nut slider 30A' from one end of the stroke to the other end of the stroke, and the opening and closing device 7 performs a closing operation to close the door. Thereafter, the drive motor 10 is further rotated in the forward direction, the lock mechanism 50' is disengaged from the nut slider 30A', and the nut slider 30A' abuts against the transmission slider 30B'.
[0103] One end of the transmission arm 35 is hinged to the transmission slider 30B', and the other end is hinged to the suction slider 40'. A biasing member (not shown), such as a spring, is provided in the housing 15, and exerts a restoring force on the transmission slider 30B' toward the side of the nut slider 30A'. When the nut slider 30A' abuts against the transmission slider 30B', the driving force transmitted from the nut slider 30A' overcomes the restoring force, and the nut slider 30A' pushes the transmission slider 30B' to move together. Further, the driving force from the drive motor 10 is transmitted to the suction slider 40' via the nut slider 30A', the transmission slider 30B', and the transmission arm 35. The suction slider 40' is connected to the suction device 8 via the pull wire C2, and thereby brings the suction device 8 into a suction operation.
[0104] When the drive motor 10 is rotated in the reverse direction, the nut slider 30A' moves away from the transmission slider 30B', and the driving force of the drive motor 10 is no longer transmitted to the transmission slider 30B'. The transmission slider 30B' is restored due to the restoring force. The suction slider 40' brings the suction device 8 into a release operation. Thereafter, the drive motor 10 is further rotated in the reverse direction, the nut slider 30A' is again engaged with the lock mechanism 50', and the opening and closing device 7 performs an opening operation to open the door.
[0105] According to the opening and closing body control device 700 as described above, by employing the transmission arm 35 to transmit the driving force from the drive motor 10 to the suction device 8, the same technical effects as in the first embodiment can be achieved. Further, since the lock mechanism 50' that drives the opening and closing device 7 and the transmission arm 35 that drives the suction device 8 are arranged laterally with respect to one screw rod 20, the opening and closing body drive device can be made more compact in the longitudinal direction.
[0106] The embodiments of the present application have been described above, but the present application is not limited to these examples.

A transmission, a brake, a clutch, or the like can be provided between the driving motor and the screw rod or between the driving motor and the gear transmission.
[0110] In the third and fourth embodiments, the other end of the push rod is directly fixed to the first locking mechanism. The fixing method can be arbitrary, such as welding, hinging, or the like, or a fastener can be used.
[0111] In the sixth embodiment, the example in which the first nut slider can engage with the first locking mechanism and the second nut slider can engage with the second locking mechanism is given, but the present application is not limited thereto. The first nut slider can engage with the second locking mechanism, and the second nut slider can engage with the first locking mechanism.
[0112] In the sixth embodiment, the example in which the length and the thread pitch of the second screw rod are different from those of the first screw rod is given, but the present application is not limited thereto. At least one of the length and the thread pitch of the second screw rod can be different from those of the first screw rod. As long as the engagement of the first nut slider 30A with the first locking mechanism 50 and the engagement of the second nut slider 30B with the second locking mechanism 60 occur at different times, the present application is not limited thereto. Alternatively, in the sixth embodiment, the first gear transmission 91 and the second gear transmission 92 can be provided to have different gear ratios. By the provision of the gear ratios, the engagement of the first nut slider 30A with the first locking mechanism 50 and the engagement of the second nut slider 30B with the second locking mechanism 60 can occur at different times.
