Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in addition to the opening / closing operation, the opening / closing body needs to perform an adsorption operation such as adsorbing to the vehicle body. Therefore, the opening / closing control device not only has the opening / closing mechanism of Patent Document 1 above, but also needs to further include, for example, a closer device such as an automatic adsorption closer. Since each of these devices has a power source such as a motor, it causes the overall size of the opening / closing control device to increase. Also, since the cost of each member with a motor is relatively high, it also causes the problem that the cost of the entire opening / closing body system is too high.

[0005] Therefore, one object of the present invention is to provide an opening / closing control device that can drive multiple components with only a single power source, thereby achieving miniaturization and cost reduction of the device. Another object of the present invention is to provide an opening / closing device having the above-mentioned opening / closing control device. [Means for solving the problem]

[0006] To achieve the above objective, one aspect of the present invention provides an opening / closing body control device comprising: an opening / closing device capable of opening and closing an opening / closing body of a mobile body relative to the body of the mobile body by performing an opening or closing operation; a suction closer device capable of adsorbing or releasing the opening / closing body to the body by performing an adsorption operation or a suction release operation; and a drive device connected to the opening / closing device and the suction closer device, which drives and operates the opening / closing device and the suction closer device with the same power source, wherein the drive device sequentially executes the suction release operation of the suction closer device and the opening operation of the opening / closing device, or sequentially executes the closing operation of the opening / closing device and the adsorption operation of the suction closer device, using the driving force from the power source.

[0007] With this configuration, a single power source can drive both the drive opening / closing device and the suction closer device to perform both the opening / closing operation of the opening / closing body and the suction / release operation of the opening / closing body to the main body of the moving body. Since only one power source is required, the entire opening / closing body control device can be miniaturized, the cost of components can be reduced, and furthermore, the total cost of the opening / closing body control device can be reduced.

[0008] In this embodiment, the drive device preferably includes: a lead screw connected to the output shaft of the power source and rotated by a driving force transmitted from the power source; a nut block provided on the lead screw and performing reciprocating linear motion along the lead screw when the lead screw rotates; a suction slider connected to the suction closer device and driving the suction closer device by movement to perform the suction operation or the suction release operation; a first locking mechanism connected to the opening / closing device and detachably connected to the nut block, which transmits the driving force to the opening / closing device when engaged with the nut block; and a second locking mechanism that contacts the suction slider and detachably connected to the nut block, which allows the nut block to move the suction slider when engaged with the nut block.

[0009] With this configuration, a drive device having a feed screw, a nut block, a suction slider, a first locking mechanism, and a second locking mechanism can transmit driving force to an opening / closing device and a suction closer device with a simple configuration.

[0010] In this embodiment, it is preferable that the first locking mechanism includes a first guide rail and a first pole that slides rotatably along the first guide rail, wherein the first pole can engage with or disengage from the nut block, and the second locking mechanism includes a second guide rail and a second pole that slides rotatably along the second guide rail, wherein the second pole can engage with or disengage from the nut block.

[0011] With this configuration, power transmission to the locking mechanism can be achieved with a simple structure.

[0012] In this embodiment, it is preferable that the nut block has a movable part that moves along the lead screw, a first protruding part that protrudes from the movable part toward the first locking mechanism and engages with or disengages from the first pole, and a second protruding part that protrudes from the movable part toward the second locking mechanism and engages with or disengages from the second pole.

[0013] With this configuration, power transmission to the locking mechanism can be achieved with a simple structure.

[0014] In this embodiment, the nut block is movable along the lead screw between a first position, a second position, and a third position, and when the nut block is in the first position, the first pole is engaged with the nut block and is at one end of the stroke of the first pole, and the second pole is not engaged with the nut block and is at one end of the stroke of the second pole, when the nut block is in the second position, the first pole begins to disengage from the nut block and is at the other end of the stroke of the first pole, and the second pole begins to engage with the nut block and is at the one end of the stroke of the second pole, and when the nut block is in the third position, the first pole is not engaged with the nut block and is at the other end of the stroke of the first pole, and the second pole is engaged with the nut block and is at the other end of the stroke of the second pole, which is preferable.

[0015] With this configuration, the opening and closing body can be sequentially closed and attracted, or sequentially released and opened.

[0016] In this embodiment, it is preferable that the axis of the output shaft of the power source lies on the same straight line as the axis of the lead screw.

[0017] With this configuration, driving force from a power source can be transmitted with a simple structure.

[0018] In this embodiment, the drive device further includes a gear transmission unit provided at the axial end of the lead screw and connected to the output shaft of the power source, and the driving force of the power source is transmitted to the lead screw via the gear transmission unit, and it is preferable that the axis of the output shaft of the power source is parallel to the axis of the lead screw.

[0019] This configuration allows for greater flexibility in the placement of power sources.

[0020] In this embodiment, it is preferable that the power source and the suction slider are provided on the same side of the feed screw in the vertical direction of the vehicle.

[0021] This configuration allows for full utilization of the space on one side of the lead screw, making the placement of the opening / closing control device more compact.

[0022] In this embodiment, it is preferable that the power source and the suction slider are provided on both sides of the feed screw in the vertical direction of the moving body.

[0023] With this configuration, the power source can effectively avoid interference with other components and prevent any impact on the operation of other components.

[0024] In this embodiment, the feed screw includes a first feed screw and a second feed screw whose axes are parallel to each other. The gear transmission part includes a first gear transmission part provided at one axial end of the first feed screw and the second feed screw, and a second gear transmission part provided at the other axial end of the first feed screw and the second feed screw. The output shaft of the power source is connected to the first gear transmission part, and the driving force of the power source is transmitted to the first feed screw through the first gear transmission part, and further transmitted to the second feed screw through the second gear transmission part. The nut block includes a first nut block provided on the first feed screw and a second nut block provided on the second feed screw. It is preferable that one of the first nut block and the second nut block can be engaged with the first locking mechanism, and the other of the first nut block and the second nut block can be engaged with the second locking mechanism.

[0025] According to such a configuration, by using a double feed screw structure, the opening and closing body can be sequentially closed and adsorbed, or sequentially adsorbed and released and opened.

[0026] In this embodiment, it is preferable that the gear ratio between the first gear transmission part and the second gear transmission part is different, or at least one of the length and the screw pitch of the second feed screw is different from that of the first feed screw.

[0027] The According to such a configuration, by providing a gear transmission part with a different gear ratio or a feed screw with different lengths and screw pitches, it is possible to realize the sequential transmission of the driving force to the opening and closing device and the adsorption closer device.

[0028] In this embodiment, the opening and closing device has a push rod, one end of which is hinged to the main body, and when a force toward the main body or a force separating it from the main body is applied, the reaction force from the main body causes the opening or closing body to perform the opening or closing operation, a push block is fixed to the push rod, the push block is connected to the first locking mechanism via a cable, and the driving force is preferably transmitted to the push rod via the cable and the push block.

[0029] With this configuration, the opening and closing mechanism can be achieved with a simple structure.

[0030] In this embodiment, it is preferable that the other end of the push rod is directly fixed to the first locking mechanism.

[0031] This configuration allows for a more compact opening / closing control device and further reduces costs.

[0032] In this embodiment, the drive device further comprises a housing that accommodates the power source, the feed screw, the nut block, the suction slider, the first locking mechanism, and the second locking mechanism, and it is preferable that a part of the push rod protrudes into the interior of the housing.

[0033] This configuration allows for further space savings and enables the opening / closing control device to be made more compact and smaller.

[0034] In this embodiment, the drive device includes a lead screw connected to the power source and rotated by the driving force transmitted from the power source; a nut block provided on the lead screw and performing reciprocating linear motion along the lead screw when the lead screw rotates; a transmission slider slidably fitted onto the lead screw; a suction slider connected to the suction closer device and driving the suction closer device by movement to perform the suction operation or the suction release operation; and a device connected to the opening / closing device and connected to the nut block so as to be able to engage or disengage, and engaging with the nut block. Preferably, the device includes a locking mechanism that transmits the driving force to the opening / closing device when the nut block is in contact with the transmission slider, and a transmission arm whose one end is hinged to the transmission slider and whose other end is hinged to the suction slider, wherein when the nut block moves and comes into contact with the transmission slider, the transmission slider moves along the lead screw together with the nut block, the driving force is transmitted from the transmission slider to the suction slider via the transmission arm, and when the nut block moves away from the transmission slider, the transmission slider returns to its original position due to a restorative force.

[0035] With this configuration, by employing a transmission slider and transmission arm, a single motor can drive both the opening / closing device and the suction closer device to perform both the opening / closing operation and the suction release / suction operation of the opening / closing body. Furthermore, the entire opening / closing body control device can be made smaller, and in particular, the opening / closing body control device can be made more compact in the longitudinal direction of the lead screw, further reducing the cost of components and, even further, the overall cost of the opening / closing body control device.

[0036] Another aspect of the present invention is an opening / closing body equipped with the above-described opening / closing body control device. [Effects of the Invention]

[0037] According to the present invention, the opening / closing control device can drive multiple components with only a single power source, thereby enabling miniaturization and cost reduction of the opening / closing control device. [Brief explanation of the drawing]

[Figure 9] Figure 9 is a schematic diagram of the opening / closing control device of the seventh embodiment. [Modes for carrying out the invention]

[0039] <First Embodiment> The opening / closing control device 100 of the first embodiment of the present invention will be described below with reference to Figures 1 to 3.

[0040] As shown in Figure 1, the opening / closing control device 100 includes a drive unit 1, an opening / closing device 7, and a suction closer device 8. The opening / closing device 7 is installed on the vehicle door and can open or close the door relative to the vehicle body by performing an opening or closing operation. 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 / closing body. The suction closer device 8 is installed on the door and can attach the door to the vehicle body or release the door from the vehicle body by performing an attachment operation or an attachment release operation. The drive unit 1 is installed on the door and connected to the opening / closing device 7 and the suction closer device 8, and drives and operates the opening / closing device 7 and the suction closer device 8.

[0041] The opening / closing device 7 includes a push rod 71 and a push block 72. One end of the push rod 71 is hinged to the vehicle body. The push block 72 is fixed to the push rod 71 and connected to the drive unit 1 via a cable C1. Although the specific connection configuration is not shown in the drawings, any well-known means may be used to connect the push block 72 to the cable C1, as long as the push block 72 can receive the biasing force from the cable C1. When the drive unit 1 is operated, a driving force acts from the drive unit 1 to the push block 72 via the cable C1. At this time, the push block 72 is subjected to a force either toward the vehicle body or away from the vehicle body. Furthermore, this force is applied to the push rod 71 and acts on the vehicle body, causing the door to open and close due to the reaction force from the vehicle body.

[0042] The drive unit 1 comprises a lead screw 20, a nut block 30, a suction slider 40, a first locking mechanism 50, a second locking mechanism 60, a housing 15, and a drive motor 10. The housing 15 houses the lead screw 20, the nut block 30, the suction slider 40, the first locking mechanism 50, and the second locking mechanism 60. The drive motor 10 is an example of a power source.

[0043] The lead screw 20 is fixedly connected to the output shaft of the drive motor 10, and the axis of the lead screw 20 lies on the same straight line as the axis of the output shaft of the drive motor 10. When the drive motor 10 is operating (forward or reverse rotation), the lead screw 20 rotates due to the driving force transmitted from the drive motor 10.

[0044] The nut block 30 is provided on the feed screw 20 and has a helical wire inside, and is screwed onto the feed screw 20 to form a screw feed mechanism. When the feed screw 20 rotates, the nut block 30 reciprocates linearly along the feed screw 20. The nut block 30 has a movable part 31, a first projection 32, and a second projection 33. The movable part 31 moves along the feed screw 20, the first projection 32 protrudes from the movable part 31 toward the first locking mechanism 50 and engages with or disengages from the first pole 51 described later. The second projection 33 protrudes from the movable part 31 toward the second locking mechanism 60 and engages with or disengages from the second pole 61 described later.

[0045] The suction slider 40 is connected to the suction closer device 8 via cable C2, and the movement of the suction slider 40 drives the suction closer device 8 to perform suction or release operations. The suction closer device 8 may use any well-known structure, such as an automatic suction lock.

[0046] The first locking mechanism 50 includes a first pole 51, a first guide rail 52, and a first connecting member 53. The first locking mechanism 50 is connected to the opening / closing device 7, specifically, the first connecting member 53 is connected to the push block 72 of the opening / closing device 7 via a cable C1. The first pole 51 is rotatably connected to the first connecting member 53 via a first connecting shaft 54, in other words, the first pole 51 is rotatable around the first connecting shaft 54. This allows the first pole 51 to slide rotatably along the first guide rail 52.

[0047] The second locking mechanism 60 includes a second pole 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 pole 61 is rotatably connected to the second connecting member 63 via a second connecting shaft 64; in other words, the second pole 61 is rotatable around the second connecting shaft 64. This allows the second pole 61 to slide rotatably along the second guide rail 62. As the second pole 61 slides, the suction slider 40 is pressed by the second locking mechanism 60 and moves together with the second locking mechanism 60.

[0048] In other words, the drive unit 1 is connected to both the opening / closing device 7 and the suction closer device 8, and both the opening / closing device 7 and the suction closer device 8 are driven and operated via the same drive motor 10. Specifically, the drive unit 1, by the driving force transmitted from the drive motor 10, sequentially executes the suction release operation of the suction closer device 8 and the opening operation of the opening / closing device 7, or sequentially executes the closing operation of the opening / closing device 7 and the suction operation of the suction closer device 8.

[0049] The opening / closing body control device 100 having the above configuration can drive the opening / closing device 7 and the suction closer device 8 with the same drive motor 10 to perform the opening / closing operation and the suction operation of the opening / closing body, respectively. Therefore, only one drive motor 10 is required for the opening / closing body control device 100. Compared to opening / closing body control devices that employ a motor-equipped opening / closing device and a motor-equipped suction closer device, the entire opening / closing body control device can be made smaller, the cost of parts can be reduced, and the total cost of the opening / closing body control device can be reduced.

[0050] The operation of the opening / closing control device 100 will be explained in detail below with reference to Figures 1 to 3. Figures 1, 2, and 3 show the opening / closing control device 100 when the door is in the open state (maximum opening), when the door is in the closed state and not attached to the vehicle body, and when the door is in the closed state and attached to the vehicle body, respectively.

[0051] As shown in Figures 1 to 3, the nut block 30 is movable along the lead screw 20 between a first position P1, a second position P2, and a third position P3.

[0052] First, as shown in Figure 1, when the door is in its fully open position, the nut block 30 is in the first position P1. At this time, the first pole 51 of the first locking mechanism 50 engages with the first projection 32 of the nut block 30 and is at one end of the stroke of the first pole 51 on the first guide rail 52, while the second pole 61 of the second locking mechanism 60 does not engage with the second projection 33 of the nut block 30 and is at one end of the stroke of the second pole 61.

[0053] Next, to close the door, the opening / closing control device 100 rotates the drive motor 10 in the forward direction. The driving force from the drive motor 10 to the lead screw 20 causes the nut block 30 to move along the first guide rail 52 from the first position P1 to the second position P2. During this period, the first pole 51 maintains its engagement with the first projection 32 of the nut block 30. During this period, the engagement between the first pole 51 and the first projection 32 remains engaged, so the first pole 51 slides along the first guide rail 52 as the nut block 30 moves, biasing it towards the push block 72 of the opening / closing device 7 via the cable C1. In this way, the driving force of the drive motor 10 is transmitted to the opening / closing device 7, which then performs the closing operation, changing the door from the open state to the closed state. When the nut block 30 is in the second position P2, the first pole 51 is at the other end of its stroke, as shown in Figure 2. At this time, the second pole 61 remains at one end of its stroke.

[0054] After the door is closed, in order to attract the door to the vehicle body, the opening / closing control device 100 continues to rotate the drive motor 10 in the forward direction, causing the nut block 30 to move further from the second position P2 towards the third position P3. During this period, the first pole 51 is already at the other end of its stroke when it is in the second position P2, so the first pole 51 cannot advance any further with the nut block 30. As the nut block 30 moves further, the first pole 51 rotates around the first connecting shaft 54, and the first projection 32 of the nut block 30 begins to disengage from the first pole 51. Meanwhile, the second pole 61 begins to engage with the second projection 33 of the nut block 30 and begins to move from one end of its stroke, so that the second pole 61 comes into contact with the suction slider 40, presses against the suction slider 40, and begins to slide together with the suction slider 40. Therefore, when the second pole 61 engages with the second projection 33, the driving force from the drive motor 10 is transmitted to the suction closer device 8 via the suction slider 40 and cable C2, and the suction closer device 8 performs a suction operation to suction the door to the vehicle body. When the nut block 30 is in the third position P3, as shown in Figure 3, the first pole 51 is still not engaged with the nut block 30 and is at the other end of the stroke of the first pole 51, while the second pole 61 engages with the second projection 33 of the nut block 30 and is at the other end of the stroke of the second pole 61.

[0055] As the drive motor 10 rotates in the reverse direction, the nut block 30 moves from the third position P3 to the second position P2 and then to the first position P1. During this period, the suction slider 40 returns due to the elastic force of a spring (not shown), and the suction closer device 8 performs a release operation. When the nut block 30 reaches the second position P2, the engagement between the first projection 32 and the first pole 51 is restarted, and the driving force of the drive motor 10 is again transmitted to the opening / closing device 7 via the first locking mechanism 50, causing the opening / closing device 7 to perform an opening operation and change the door from the closed state to the open state.

[0056] With the drive device 1 described above, the same drive motor 10 can be used to open and close the door, as well as to perform suction / release. Furthermore, the opening / closing control device 100 equipped with such a drive device 1 can transmit driving force to the opening / closing device 7 and the suction closer device 8 with a simple configuration, causing the opening / closing device 7 and the suction closer device 8 to sequentially perform closing and suction operations, or suction operations and opening operations.

[0057] <Second Embodiment> The opening / closing control device 200 of the second embodiment will be described with reference to Figure 4. Below, the differences between the second embodiment and the first embodiment will be mainly described, and parts identical to those of the first embodiment will be denoted by the same reference numerals and their descriptions will be omitted.

[0058] The opening / closing control device 200 has a gear transmission unit 90, which is provided at one axial end of the lead screw 20 and is fixedly connected to the output shaft of the drive motor 10. When the output shaft of the drive motor 10 rotates, the driving force is transmitted to the lead screw 20 via the gear transmission unit 90.

[0059] In the second embodiment, the drive motor 10 is provided such that its output shaft is parallel to the output shaft of the lead screw 20. Specifically, the drive motor 10 and the suction slider 40 are arranged on the same side with respect to the lead screw 20 in the vertical direction of the vehicle, for example, both are positioned below the lead screw 20.

[0060] The remaining parts of the opening / closing control device 200 are the same as those of the opening / closing control device 100. This allows for the same effects as in the first embodiment, as well as further improvement in the flexibility of the placement of the drive motor 10. Furthermore, the space below the lead screw 20 can be fully utilized, making the placement of the opening / closing control device 200 more compact.

[0061] <Third Embodiment> The opening / closing control device 300 of the third embodiment will be described with reference to Figure 5. Below, the differences between the third embodiment and the second embodiment will be mainly described, and parts identical to those of the second embodiment will be denoted by the same reference numerals and their descriptions will be omitted.

[0062] In the third embodiment, an opening / closing device 7A is used instead of the opening / closing device 7. The opening / 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 rest of the opening / closing control device 300 is the same as that of the opening / closing control device 200.

[0063] In this way, in addition to achieving the same effects as the first and second embodiments, cables can be omitted, making the opening / closing control device more compact and further reducing costs.

[0064] <Fourth Embodiment> The opening / closing control device 400 of the fourth embodiment will be described with reference to Figure 6. Below, the differences between the fourth embodiment and the third embodiment will be mainly described, and parts identical to those of the third embodiment will be denoted by the same reference numerals and their descriptions will be omitted.

[0065] The main difference between the fourth embodiment and the third embodiment is the adoption of an opening / closing device 7B instead of an opening / closing device 7A. In the opening / closing device 7A, the entire push rod 71 is located outside the housing 15, whereas in the opening / closing device 7B, a portion of the push rod 71 that is separated from the vehicle body protrudes into the housing 15. The remaining part of the opening / closing body control device 400 is the same as that of the opening / closing body control device 300.

[0066] In this way, in addition to achieving the same effects as the third embodiment, it is also possible to further save space occupied by the opening and closing device, making the entire opening and closing device control unit 400 even more compact and smaller.

[0067] <Fifth Embodiment> The opening / closing control device 500 of the fifth embodiment will be described with reference to Figure 7.

[0068] The difference between the fifth embodiment and the fourth embodiment is that in the opening / closing control device 500, the drive motor 10 and the suction slider 40 are positioned on different sides of the lead screw 20 in the vertical direction of the vehicle. For example, the suction slider 40 is positioned below the lead screw 20, and the drive motor 10 is positioned above the lead screw 20. The remaining parts of the opening / closing control device 500 are the same as those of the opening / closing control device 400.

[0069] In this way, in addition to achieving the same effects as in the fourth embodiment, since various components are attached to the door, if other components are located below the drive unit 1, the drive motor can avoid interference with the other components and avoid affecting the operation of the other components.

[0070] <Sixth Embodiment> The opening / closing control device 600 of the sixth embodiment will be described with reference to Figure 8. Below, the differences between the sixth embodiment and the second embodiment will be mainly described, and parts identical to those of the second embodiment will be denoted by the same reference numerals and their descriptions will be omitted.

[0071] The main difference between the sixth embodiment and the second embodiment is that the sixth embodiment uses drive unit 1A instead of drive unit 1.

[0072] In the drive unit 1A, the lead screw includes a first lead screw 21 and a second lead screw 22, with the axes of the first lead screw 21 and the second lead screw 22 being parallel, but the length and screw pitch of the second lead screw 22 being different from those of the first lead screw 21. The gear transmission section includes a first gear transmission section 91 and a second gear transmission section 92, with the first gear transmission section 91 provided at one axial end of the first lead screw 21 and the second lead screw 22, and the second gear transmission section 92 provided at the other axial end of the first lead screw 21 and the second lead screw 22. The nut block includes a first nut block 30A and a second nut block 30B, with the first nut block 30A provided on the first lead screw 21 and the second nut block 30B provided on the second lead screw 22. The first nut block 30A is engageable with the first locking mechanism 50, and the second nut block 30B is engageable with the second locking mechanism 60.

[0073] The drive motor 10 has its output shaft connected to the first gear transmission unit 91, and its driving force is transmitted to the first lead screw 21 via the first gear transmission unit 91, causing the first lead screw 21 to rotate. This driving force is then transmitted to the second gear transmission unit 92, and subsequently transmitted to the second lead screw 22 via the second gear transmission unit 92, causing the second lead screw 22 to rotate.

[0074] Since the operating principle of drive unit 1A is the same as that of drive unit 1, a detailed explanation is omitted here. The second lead screw 22 is provided with a length and screw pitch different from that of the first lead screw 21, so that the engagement between the first nut block 30A and the first locking mechanism 50, and the engagement between the second nut block 30B and the second locking mechanism 60 occur at different times. As a result, the door can perform opening and suction operations sequentially, and then release and closing operations sequentially.

[0075] The remaining parts of the opening / closing control device 600 are the same as those of the opening / closing control device 200. In this way, the same effects as in the second embodiment can be achieved with a double feed screw configuration.

[0076] <Seventh Embodiment> The seventh embodiment of the opening / closing control device 700 will be described with reference to Figure 9. Below, the differences between the seventh embodiment and the first embodiment will be mainly described, and parts identical to those in the first embodiment will be denoted by the same reference numerals and their descriptions will be omitted.

[0077] The main difference between the seventh embodiment and the first embodiment is that the seventh embodiment uses drive unit 1B instead of drive unit 1.

[0078] The drive unit 1B includes a lead screw 20, a nut block 30A', a transmission slider 30B', a suction slider 40', a locking mechanism 50', a transmission arm 35, a housing 15, and a drive motor 10. The drive motor 10, lead screw 20, etc., are configured the same as in the first embodiment. Note that the locking mechanism 50' is the same as the first locking mechanism 50 in the sixth embodiment, and the nut block 30A' is the same as the first nut block 30A in the sixth embodiment, so descriptions of these components will be omitted as appropriate.

[0079] The nut block 30A' is attached to the lead screw 20. When the drive motor 10 rotates the lead screw 20, the nut block 30A' moves back and forth along the lead screw 20.

[0080] The locking mechanism 50' is connected to the opening / closing device 7 and is engageable with the nut block 30A', and the specific engagement configuration is substantially the same as the engagement between the first locking mechanism 50 and the first nut block 30A in the sixth embodiment. While the locking mechanism 50' is engaged with the nut block 30A', the driving force of the drive motor 10 is transmitted to the push rod 71 of the opening / closing device 7. During this time, when the drive motor 10 rotates in the forward direction, the opening / closing device 7 performs a closing operation to move the 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 move the door from the closed state to the open state.

[0081] The transmission slider 30B' does not have a helical wire inside and is externally fitted to the lead screw 20 so as to be slidable. When the drive motor 10 rotates in the forward direction, the lead screw 20 rotates and the nut block 30A' moves onto the transmission slider 30B'. As the drive motor 10 rotates in the forward direction, the locking mechanism 50' moves together with the nut block 30A', moving from one end of its stroke to the other, and the opening / closing device 7 performs a closing operation to close the door. Subsequently, the drive motor 10 rotates further in the forward direction, disengaging the locking mechanism 50' from the nut block 30A', and the nut block 30A' comes into contact with the transmission slider 30B'.

[0082] The transmission arm 35 is hinged at one end to the transmission slider 30B' and at the other end to the suction slider 40'. The housing 15 is also provided with a biasing member (not shown), such as a spring, that generates a restorative force toward the nut block 30A' relative to the transmission slider 30B'. When the nut block 30A' comes into contact with the transmission slider 30B', the driving force transmitted from the nut block 30A' resists this restorative force, causing the nut block 30A' to push the transmission slider 30B' and move together. Furthermore, the driving force from the drive motor 10 is transmitted to the suction slider 40' via the nut block 30A', the transmission slider 30B', and the transmission arm 35. The suction slider 40' is connected to the suction closer device 8 via cable C2, thereby driving the suction closer device 8 to perform the suction operation.

[0083] When the drive motor 10 rotates in the reverse direction, the nut block 30A' moves away from the transmission slider 30B', and the power transmitted by the drive motor 10 is no longer transmitted to the transmission slider 30B', causing the transmission slider 30B' to return to its original position due to its restoring force. The suction slider 40' causes the suction closer device 8 to perform a release operation. Subsequently, the drive motor 10 rotates further in the reverse direction, causing the nut block 30A' to engage with the locking mechanism 50' again, and the opening / closing device 7 performs an opening operation to open the door.

[0084] As described above, the opening / closing control device 700 transmits the driving force from the drive motor 10 to the suction closer device 8 using the transmission arm 35, thereby achieving the same technical effects as in the first embodiment. Furthermore, since the locking mechanism 50' that drives the opening / closing device 7 and the transmission arm 35 that drives the suction closer device 8 are arranged laterally with respect to a single lead screw 20, the opening / closing drive device can be made more compact when placed vertically.

[0085] Although embodiments of the present invention have been described above, the present invention is not limited to these examples. Additions, deletions, and design modifications of components as appropriate by those skilled in the art, or combinations of some of the features of the embodiments, are also included within the scope of the present invention, as long as they do not contradict the spirit of the invention.

[0086] In the above embodiment, a vehicle was described as the moving body and a vehicle door as the opening / closing body, but the embodiment is not limited to this. The moving body may be other vehicles such as ships, trains, or aircraft, and the opening / closing body may be a hatch door, a trunk door, or the like.

[0087] In the above embodiment, a motor was described as an example of a power source, but the power source is not limited to this, and known power sources such as batteries or manual operation may be used.

[0088] In the above embodiment, the nut block and the locking mechanism achieve engagement and disengagement by employing a pole and a protrusion, but this is not limited to this, and it may also be achieved by other appropriate shapes. In the present invention, examples have been given in which the drive motor and the lead screw are connected directly or via a gear transmission, but the connection between the drive motor and the lead screw is not limited to this, and a transmission, brake, clutch, etc. may be provided between the drive motor and the lead screw, or between the drive motor and the gear transmission.

[0089] In the third and fourth embodiments, the other end of the push rod is directly fixed to the first locking mechanism, but the method of fixing may be any method. For example, it may be fixed by welding, hinge connection, or by fastening device.

[0090] In the sixth embodiment, it was stated that the first nut block is engageable with the first locking mechanism and the second nut block is engageable with the second locking mechanism, but it is also possible that the first nut block is engageable with the second locking mechanism and the second nut block is engageable with the first locking mechanism.

[0091] In the sixth embodiment, it was stated that the second feed screw and the first feed screw differ in both length and screw pitch, but the second feed screw and the first feed screw may differ in at least one of their lengths and screw pitches. The engagement between the first nut block 30A and the first locking mechanism 50, and the engagement between the second nut block 30B and the second locking mechanism 60 can be made to occur at different times. Alternatively, in the sixth embodiment, the first gear transmission section 91 and the second gear transmission section 92 may be provided with different gear ratios. By setting these gear ratios, the engagement between the first nut block 30A and the first locking mechanism 50, and the engagement between the second nut block 30B and the second locking mechanism 60 can also be made to occur at different times.
