[0002] Aircraft are typically equipped with a door lifting device, which lifts the door to a designated position during the opening and closing process and allows the door stop block to bypass the door frame stop block to achieve the opening and closing of the door.

[0003] Examples of cabin door lifting devices include the cabin door lifting assist mechanism disclosed in Patent Document 1, the aircraft cabin door lifting device disclosed in Patent Document 2, the non-dangerous cabin door latch lifting mechanism disclosed in Patent Document 3, the passenger aircraft cabin door lifting mechanism disclosed in Patent Document 4, the passenger aircraft cabin door lifting mechanism disclosed in Patent Document 5, and the cabin door lifting mechanism disclosed in Patent Document 6.

[0008] Patent Document 5: CN110359799A

[0009] Patent Document 6: US005255876A

[0010] However, the door lifting assist mechanism disclosed in Patent Document 1 can only lift the door, the aircraft door lifting device disclosed in Patent Document 2 can only make the door move in the vertical direction, the non-dangerous door latch lifting mechanism disclosed in Patent Document 3 restricts the movement of multiple parts, the passenger aircraft door lifting mechanism disclosed in Patent Document 4 only completes the lifting movement of the door, the passenger aircraft door lifting mechanism disclosed in Patent Document 5 only completes the lifting movement of the door, and the door lifting mechanism disclosed in Patent Document 6 can only make the door move in the vertical direction. Therefore, it is impossible to use the functions of the above devices to adjust the gap and step difference between the door and the door frame during the installation and debugging of the aircraft door, and it is necessary to repeatedly disassemble and assemble the mechanism and adjust the attitude by adding pads.

[0011] In response to the above situation, there is an urgent need for a structure that can be used in conjunction with a hatch lifting device to adjust the gap and step difference between the hatch and the door frame. Summary of the Invention

[0012] The present invention was made in view of the above-mentioned problems, and its purpose is to provide a door position adjustment device and an aircraft that can easily adjust the gap and step difference between the door and the door frame.

[0013] To achieve the above objectives, the present invention provides a hatch position adjustment device, comprising: a first main body; a first yaw axis for connecting to one of a hatch side component and a door frame side component, the first main body being supported on the first yaw axis in a manner movable along the first yaw axis; a first spanning axis for connecting to the other of the hatch side component and the door frame side component, and extending intersecting the first yaw axis, the first main body being supported on the first spanning axis in a manner movable along the first spanning axis; a first yaw locking mechanism capable of switching between a state restricting movement of the first main body relative to the first yaw axis and a state allowing movement of the first main body relative to the first yaw axis; and a first spanning locking mechanism capable of switching between a state restricting movement of the first main body relative to the first spanning axis and a state allowing movement of the first main body relative to the first spanning axis.

[0014] Here, the extension direction of the first heading axis is not required to be strictly consistent with the heading of the upper-level equipment such as the aircraft using the door position adjustment device; it only needs to be roughly consistent. The extension direction of the first spanwise axis is not required to be consistent with the spanwise direction of the upper-level equipment such as the aircraft using the door position adjustment device.

[0015] According to the hatch position adjustment device of the present invention, when the first heading axis is connected to one of the hatch side component and the door frame side component and the first spanwise axis is connected to the other of the hatch side component and the door frame side component, by moving the first main body relative to the first heading axis in the heading direction and relative to the first spanwise axis in the spanwise direction, while ensuring that the hatch and the door frame are assembled in a suitable position, the hatch can be infinitely adjusted in the heading and spanwise directions, thereby controlling and adjusting the gap and step difference between the hatch and the door frame.

[0016] Furthermore, in the hatch position adjustment device of the present invention, the first heading locking mechanism preferably includes: a first heading bushing, which is detachably fitted onto the first heading axis in a manner that prevents relative movement, passes through and supports a first portion of the first main body, and is provided with an external thread; and a pair of first heading locking nuts, which are provided with internal threads that engage with the external threads of the first heading bushing, and clamp the first portion from both sides in the extending direction of the first heading axis.

[0017] The hatch position adjustment device according to the present invention, compared with the case where the pair of first yaw locking nuts are directly screwed into the first yaw axis, helps to avoid fatigue problems that may exist in the connection part and ensures the strength performance of the main load-bearing first yaw axis and the structural components connected thereto.

[0018] Furthermore, the hatch position adjustment device of the present invention preferably further includes a first yaw movement bushing, which is sleeved on the first yaw axis in such a manner as to be arranged with the first yaw bushing along the first yaw axis, and passes through and supports a second part of the first main body that is different from the first part.

[0023] According to the hatch position adjustment device of the present invention, the first spanwise locking mechanism has a simple and compact structure, which helps to reduce manufacturing costs.

[0024] Furthermore, the hatch position adjustment device of the present invention preferably includes: a second main body portion disposed below or above the first main body portion; a second yaw axis for connecting to one of the hatch side component and the door frame side component, and parallel to the first yaw axis, the second main body portion being supported on the second yaw axis in a manner movable along the second yaw axis; a second spanning axis for connecting to the other of the hatch side component and the door frame side component, the second main body portion being supported on the second spanning axis in a manner movable along the second spanning axis; a second yaw locking mechanism capable of switching between a state restricting the movement of the second main body portion relative to the second yaw axis and a state allowing the movement of the second main body portion relative to the second yaw axis; and a second spanning locking mechanism capable of switching between a state restricting the movement of the second main body portion relative to the second spanning axis and a state allowing the movement of the second main body portion relative to the second spanning axis.

[0025] According to the hatch position adjustment device of the present invention, when the first heading axis and the second heading axis are connected to one of the hatch side component and the door frame side component, and the first spanwise axis and the second spanwise axis are connected to the other of the hatch side component and the door frame side component, it helps to stably realize the movement of the first main body relative to the first heading axis in the heading direction and the movement of the second main body relative to the second heading axis in the spanwise direction.

[0026] Furthermore, in the hatch position adjustment device of the present invention, the second heading locking mechanism preferably includes: a second heading bushing, which is detachably fitted onto the second heading axis in a manner that prevents relative movement, passes through and supports the second main body, and is provided with external threads; and a pair of second heading locking nuts, which are provided with internal threads that engage with the external threads of the second heading bushing, and clamp the second main body from both sides in the extension direction of the second heading axis.

[0027] The hatch position adjustment device according to the present invention, compared with the case where the pair of second yaw locking nuts are directly screwed into the second yaw shaft, helps to avoid fatigue problems that may exist at the connection part and ensures the strength performance of the main load-bearing second yaw shaft and the structural components connected thereto.

[0088] (Structure of the hatch position adjustment device)

[0089] like Figure 1 and Figure 2 As shown, the hatch position adjustment device 1 includes a first unit 10 and a second unit 20 located below the first unit 10. When the hatch is in the closed state, the bottom height of the hatch body is basically flush with the door frame. At this time, the first unit 10 and the second unit 20 connect and lock the hatch in the closed position (e.g., refer to...). Figure 1 On the other hand, when the hatch is in the raised position, the bottom of the hatch body is higher than the door frame. At this time, the first unit 10 and the second unit 20 connect the hatch and lock it in the raised position (for example, refer to...). Figure 2 ).

[0091] like Figures 1 to 3 As shown, the first unit 10 includes: a first main body 11; a first heading axis 12 for connecting to one of the door-side component 30 and the door frame-side component 40, the first main body 11 being supported on the first heading axis 12 in a manner that allows it to move along the first heading axis 12; a first spanning axis 13 for connecting to the other of the door-side component 30 and the door frame-side component 40, and extending intersecting the first heading axis 12, the first main body 11 being supported on the first spanning axis 13 in a manner that allows it to move along the first spanning axis 13; a first heading locking mechanism 14 that can switch between a state that restricts the movement of the first main body 11 relative to the first heading axis 12 and a state that allows the movement of the first main body 11 relative to the first heading axis 12; and a first spanning locking mechanism 15 that can switch between a state that restricts the movement of the first main body 11 relative to the first spanning axis 13 and a state that allows the movement of the first main body 11 relative to the first spanning axis 13.

[0092] Here, as Figures 1 to 3As shown, the first yaw axis 12 is connected to the hatch side component 30 (specifically, both ends of the first yaw axis 12 are rotatably supported on the hatch side component 30, such as a support plate, via bearings), and the first spanning axis 13 is connected to the door frame side component 40 (specifically, one end of the first spanning axis 13 is connected to the door frame side component 40, such as a hinge, via a universal joint). Furthermore, the first main body 11 is configured to rotate relative to the first yaw axis 12. And the first spanning axis 13 extends perpendicularly to the first yaw axis 12.

The thread (which may be provided only on a portion of the first directional bushing 141 in the axial direction, or it may be provided on the entire first directional bushing 141 in the axial direction); a pair of first directional locking nuts 142a and 142b, which are provided with internal threads that engage with the external threads of the first directional bushing 141, and clamp the first portion 111 from both sides in the extension direction of the first directional shaft 12 (the first portion 111 may be clamped directly or clamped through a washer).

[0094] In addition, such as Figure 3 , Figure 4A and Figure 4B As shown, the first unit 10 also includes a first yaw movement bushing 16, which is sleeved on the first yaw axis 12 in a manner that is arranged with the first yaw bushing 141 along the first yaw axis 12, and passes through and supports the second part 112 of the first main body 11, which is different from the first part 111 (in the illustrated example, it is in the shape of an arm perpendicular to the first yaw axis 12, but is not limited thereto).

[0095] In addition, such as Figure 3 , Figure 4A and Figure 4B As shown, the first unit 10 also includes a first yaw connecting bushing 17, which is sleeved on the first yaw axis 12 (specifically, on the side opposite to the first yaw moving bushing 141 of the first yaw moving bushing 16) and is used for connecting external devices.

[0096] In addition, such as Figure 4A , Figure 4Cand Figure 6 As shown, the first spanwise locking mechanism 15 includes: a first spanwise bushing 151, which is rotatably fitted onto the first spanwise shaft 13 and has an external thread that engages with an internal thread on the first main body 11; a first spanwise locking nut 152, which has an internal thread that engages with the external thread of the first spanwise bushing 151; and a pair of first locking washers 153, which have mating surfaces facing each other (with structures such as protrusions and recesses to inhibit relative rotation), one of the pair of first locking washers 153 ( Figure 4C The middle part (located on the upper side) is fixed relative to the first main body 11 (e.g., fixed to each other by snap-fit), the other side ( Figure 4C The first locking washer 153 (located on the lower side) is fixed relative to the first spanwise bushing 151 (e.g., fixed to each other by snap-fit), and the pair of first locking washers 153 are held by the first spanwise locking nut 152 and the first body portion 11 from both sides in the extension direction of the first spanwise shaft 13.

[0097] Here, as Figure 4A and Figure 4C As shown, the first spanning shaft 13 passes through the first spanning bushing 151. One end of the first spanning shaft 13 is provided with a flange 1311 and an ear 1312 for connecting with the door frame side component 40. The other end of the first spanning shaft 13 is provided with an external thread for the nut W3 to be screwed in. The nut W3 and the flange 1311 abut against the first spanning bushing 151 from both sides of the extension direction of the first spanning shaft 13.

[0098] (Adjustment movements in Unit 1)

[0099] When adjusting the heading position of the hatch, for example, first loosen the first heading locking nuts 142a and 142b (i.e., tighten them in the direction of separation from the first main body 11), then move the first main body 11 to the desired position along the first heading axis 12, and then tighten the first heading locking nuts 142a and 142b (i.e., tighten them until they abut against the first main body 11).

[0100] Furthermore, when adjusting the spanwise position of the hatch, for example, the first spanwise locking nut 152 is loosened (i.e., screwed in the direction separating it from the paired first locking washers 153), so that the paired first locking washers 153 separate from each other along the first spanwise axis 13. Then, the first spanwise bushing 151 is rotated to move the first main body 11 to the desired position along the first spanwise axis 13, and then the first spanwise locking nut 152 is tightened (i.e., tightened until the paired first locking washers 153 abut against each other).

[0101] (Structure of Unit 2)

[0102] like Figures 1 to 3As shown, the second unit 20 includes: a second main body 21 disposed below the first main body 11; a second yaw axis 22 for connecting to one of the hatch side component 30 and the door frame side component 40, and parallel to the first yaw axis 12, the second main body 21 being supported on the second yaw axis 22 in a manner movable along the second yaw axis 22; and a second spanning axis 23 for connecting to the other of the hatch side component 30 and the door frame side component 40, the second main body 21 being supported on the second yaw axis 22 in a manner movable along the second yaw axis 22; and a second spanning axis 23 for connecting to the other of the hatch side component 30 and the door frame side component 40, the second main body 21 being supported on the second yaw axis 22 in a manner movable along the second yaw axis 12; and a second spanning axis 23 for connecting to the other of the hatch side component 30 and the door frame side component 40. The second span axis 22 is supported in a manner that allows movement of the second body part 21 relative to the second span axis 22; the second heading locking mechanism 24 is switchable between a state that restricts the movement of the second body part 21 relative to the second heading axis 22 and a state that allows the movement of the second body part 21 relative to the second heading axis 22; and the second span locking mechanism 25 is switchable between a state that restricts the movement of the second body part 21 relative to the second span axis 23 and a state that allows the movement of the second body part 21 relative to the second span axis 23.

[0103] Here, as Figures 1 to 3 As shown, the second yaw axis 22 is connected to the door side component 30, and the second spanning axis 23 is connected to the door frame side component 40. Furthermore, the second main body 21 is configured to rotate relative to the second yaw axis 22. The second spanning axis 23 extends perpendicularly to the second yaw axis 22.

[0104] In addition, such as Figure 5A and Figure 5B As shown, the second heading locking mechanism 24 includes: a second heading bushing 241, which is detachably fitted onto the second heading shaft 22 in a manner that prevents relative movement (specifically, after being fitted onto the second heading shaft 22, the second heading bushing 241 is fixed to the second heading shaft 22 by threaded parts such as bolts W4 and W5), passes through and supports the second main body 21, and is provided with external threads (which may be provided only on a portion of the second heading bushing 241 in the axial direction, or may be provided on the entire second heading bushing 241 in the axial direction); and a pair of second heading locking nuts 242a and 242b, which are provided with internal threads that engage with the external threads of the second heading bushing 241, and clamp the second main body 21 from both sides in the extension direction of the second heading shaft 22 (which may be directly clamping the second main body 21, or clamping the second main body 21 through a gasket).

[0105] In addition, such as Figure 5A , Figure 5C and Figure 6As shown, the second spanwise locking mechanism 25 includes: a second spanwise bushing 251, which is rotatably fitted onto the second spanwise shaft 23 and has an external thread that engages with an internal thread on the second main body 21; a second spanwise locking nut 252, which has an internal thread that engages with the external thread on the second main body 21; and a pair of second locking washers 253, which have mating surfaces facing each other (with structures such as protrusions and recesses to inhibit relative rotation), one of the pair of second locking washers 253 ( Figure 5C The middle part (located on the upper side) is fixed relative to the second main body 21 (e.g., fixed to each other by snap-fit), the other side ( Figure 5C The pair of second locking washers 253 are fixed relative to the second spanning bushing 251 (e.g., by snap-fitting) and are held by the second spanning locking nut 252 and the second body portion 21 from both sides of the extension direction of the second spanning shaft 23.

One end of the second spanning shaft 23 is provided with a flange 2311 and an ear piece 2312 for connecting with the door frame side component 40. The other end of the second spanning shaft 23 is provided with an external thread for the nut W6 to be screwed in. The nut W6 and the flange 2311 abut against the second spanning bushing 251 from both sides of the extension direction of the second spanning shaft 23.

[0107] (Adjustment movements in Unit 2)

[0108] When adjusting the heading position of the hatch, for example, first loosen the second heading locking nuts 242a and 242b (i.e., tighten them in the direction of separation from the second main body 21), then move the second main body 21 to the desired position along the second heading axis 22, and then tighten the second heading locking nuts 242a and 242b (i.e., tighten them until they abut against the second main body 21).

[0109] Furthermore, when adjusting the spanwise position of the hatch, for example, the second spanwise locking nut 252 is loosened (i.e., tightened in the direction of separation from the paired second locking washers 253), so that the paired second locking washers 253 separate from each other along the second spanwise axis 23. Then, the second spanwise bushing 251 is rotated to move the second main body 21 to the desired position along the second spanwise axis 23, and then the second spanwise locking nut 252 is tightened (i.e., tightened until the paired second locking washers 253 abut against each other).
