Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following describes in further detail the embodiments of the present application with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment provides a water area movable apparatus 300, which includes a movable body 301 and a water area propeller 200, wherein the water area propeller 200 is movably connected to the movable body 301. The water propulsion 200 acts as an auxiliary propulsion for the water movable apparatus 300, which is configured to change its attitude with respect to the movable body 301 to place the water propulsion 200 under the water surface when it is required to be used, thereby providing propulsion for the movement of the movable body 301. When the water mover 200 is not required to be used, it is placed above the water surface to reduce resistance to water flow experienced by the movable body 301 when it is moving.

The water area movable device 300 of this embodiment may be various water area vehicles such as a commercial ship, a passenger ship, a yacht, a fishing boat, a sailing boat, a civil ship, and the like, and may also be devices that can move in a water area such as a water area inspection device, a water area management device, and a water area environment monitoring device, which are not limited in this disclosure. When the water area movable apparatus 300 is a ship of various types, the movable body 301 is a ship body accordingly. The water propulsion 200 of the present embodiment may be an outboard motor, a pod propulsion, or the like, capable of providing power. The water propulsion 200 may be mounted in the head, tail, or side, and may be used as a side propulsion when mounted on the side to assist in steering the water mobile device 300, etc.

As shown in fig. 2 and referring to fig. 1, the present embodiment provides a water area propeller 200, which includes a main machine 201 and a warping apparatus 100. The tilting device 100 comprises a fixture 1 and a tilting bracket 20, and a host 201 is connected to the tilting bracket 20. The fixture 1 is fixed on the movable body 301, and the tilting bracket 20 is connected with the fixture 1 and can tilt relative to the fixture 1, so that the host 201 connected to the tilting bracket 20 can tilt relative to the movable body 301. In this way, when the water propeller 200 is not needed, the host 201 is lifted above the water surface after the lifting bracket 20 lifts, and when the water propeller 200 is needed, the host 201 is returned below the water surface after the lifting bracket 20 is unlocked and released. Illustratively, the host 201 includes at least a driving motor and a propeller, where the driving motor is used to drive the propeller to rotate, so as to implement propulsion of the water propeller 200.

The structural parts of the tilting device 100 are exemplarily described herein: as shown in fig. 3 to 5, the tilting device 100 includes a jig 1, a tilting bracket 20, and a limiting bracket 30. The fixture 1 is provided with a tilting main shaft 11 and a sliding groove 12, the sliding groove 12 comprises a sliding section 121, a limiting section 122 and an unlocking section 123, the groove depth of the sliding section 121 is smaller than that of the limiting section 122, and the groove depth of the limiting section 122 is smaller than that of the unlocking section 123. The tilting bracket 20 is connected to the tilting spindle 11 and configured to tilt relative to the jig 1, the tilting bracket 20 being adapted to be connected to a host 201 (shown in fig. 2). The limiting bracket 30 comprises a bracket body 31 and a limiting shaft 32, one end of the bracket body 31 is rotationally connected with the tilting bracket 20, the other end of the bracket body is connected with the limiting shaft 32, the limiting shaft 32 is configured to slide relative to the bracket body 31 along the direction parallel to the tilting main shaft 11, and the end part of the limiting shaft 32 is in sliding fit with the sliding groove 12. One end of the limiting section 122 is set to a locking position W1, and the other end of the limiting section 122 is connected to the unlocking section 123, so that the limiting shaft 32 is separated from the locking position W1 under a driving force and enters the unlocking section 123.

As shown in fig. 6 to 7, and referring to fig. 1 and 2, when some embodiments are employed, the clip 1 includes two clips 10, and the two clips 10 are disposed opposite to each other at a spacing. Correspondingly, two sliding grooves 12 are arranged, and the two sliding grooves 12 are respectively arranged on opposite sides of the two clamping lugs 10. The tilting bracket 20 is at least partially installed between the two clamping lugs 10, so that two ends of the tilting main shaft 11 penetrate through the tilting bracket 20 and are rotatably installed on the two clamping lugs 10, so that the tilting bracket 20 rotates around the axis of the tilting main shaft 11 under the action of a driving force, and the tilting bracket 20 rotates relative to the two clamping lugs 10 and then tilts. Meanwhile, the tilting bracket 20 is also connected with the host 201, and when the tilting bracket 20 tilts, the host 201 is driven to move, so that the host 201 presents different postures relative to the movable body 301.

The bracket body 31 is disposed between the two lugs 10, and the bracket body 31 includes a first end 311 and a second end 312. Both sides of the first end 311 of the bracket body 31, which are close to the two lugs 10, are provided with limiting shafts 32. The limiting shaft 32 is arranged in parallel with the axis of the tilting main shaft 11, one end, close to the sliding groove 12, of the limiting shaft 32 is in sliding fit in the sliding groove 12, so that the two clamping lugs 10 play a supporting role on the two clamping lugs from two sides of the bracket body 31, and the first end 311 of the bracket body 31 can move relative to the sliding groove 12 through the limiting shaft 32. In particular, the end of the limiting shaft 32 near the chute 12 is provided with a bushing 321, the outer diameter of the bushing 321 is larger than the outer diameter of the limiting shaft 32, and the outer diameter of the bushing 321 is smaller than the minimum slot width of the chute 12. The bushing 321 is made of flexible material and is abutted against the wall surface of the chute 12, so that the bushing 321 plays a role in damping and buffering the movement of the limiting shaft 32 in the chute 12.

The second end 312 of the bracket body 31 is rotatably connected to the tilting bracket 20 by a rotation shaft 22. The rotation shaft 22 is disposed parallel to the axis of the tilting main shaft 11, and two ends of the rotation shaft 22 are respectively fixed on two opposite sides of the tilting bracket 20, so that the rotation shaft 22 is fixed relative to the tilting bracket 20. The second end 312 of the holder body 31 is provided with a through hole 3120 through which the rotation shaft 22 passes, so that the second end 312 of the holder body 31 is rotatably mounted at the rotation shaft 22 such that the second end 312 of the holder body 31 can rotate about the axis of the rotation shaft 22.

In particular, the tilting bracket 20 is provided with an ear plate 21, and the ear plate 21 is provided with a through hole 210 through which the rotation shaft 22 passes. The ear plate 21 is located at approximately the middle position of the rotation shaft 22, and a torsion spring 23 is sleeved at the middle position of the rotation shaft 22.

The torsion spring 23 provides an acting force for opening the support body 31 relative to the tilting support 20, so that the support body 31 opens relative to the tilting support 20 under the action of the tension force of the torsion spring 23, namely, the opening direction of the support body 31 relative to the rotating shaft 22 is opposite to the rotating direction of the tilting support 20 relative to the rotating shaft 22, and the limiting shaft 32 is forced to open relative to the tilting support 20 along with the opening of the support body 31, so that the limiting shaft 32 always has a tendency of outwards abutting when the tilting support 20 is tilted or released, the outer peripheral surface of the limiting shaft 32 slides against the inner side wall of the chute 12, and the sliding of the limiting shaft 32 by the inner side wall of the chute 12 plays a role in guiding.

In this way, when the tilting bracket 20 is tilted under the action of a driving force, the driving force can be provided by a power device or manpower and is applied to the tilting bracket 20, so that the tilting bracket 20 can tilt relative to the movable body 301, the driving force appearing in the following description is equivalent to the driving force at present, and the tilting bracket 20 drives the bracket body 31 to move along with the tilting bracket 20 through the rotating shaft 22 fixedly connected with the driving force. At this time, the limiting shaft 32 disposed on the first end 311 of the bracket body 31 is limited by the limiting effect of the chute 12 and moves along a fixed track, so that the second end 312 of the bracket body 31 rotates around the axis of the rotating shaft 22, and the bracket body 31 changes posture relative to the tilting bracket 20. In the process of changing the posture of the stand body 31 relative to the stand 20, the stand body 31 can limit the tilting angle of the stand 20, so that the tilting process of the stand 20 is more gentle. The tilting angle of the tilting bracket 20 is an angle by which the free end of the tilting bracket 20 is rotated from a position abutting the jig 1 to a position separated from the jig 1 about the rotation axis 22. Meanwhile, when the tilting bracket 20 tilts under the action of a driving force, the tilting bracket 20 drives the bracket body 31 to move along with the tilting bracket 20 through the rotating shaft 22 fixedly connected with the tilting bracket 20, so that the limiting shaft 32 moves in the chute 12 towards the tilting direction of the tilting bracket 20 to abut against the inner side wall of the chute 12, and when the tilting bracket 20 continues tilting, the limiting shaft 32 slides upwards close to the inner side wall of the chute 12. The sliding of the limiting shaft 32 is directly guided by the inner side wall of the chute 12.

When the tilting bracket 20 falls back under the action of gravity after being released, the bracket body 31 also falls back under the action of gravity, so that the limiting shaft 32 moves in the chute 12 towards the falling direction of the tilting bracket 20 until the limiting shaft abuts against the inner side wall of the chute 12, and when the bracket body 31 continues to fall back, the limiting shaft 32 always clings to the inner side wall of the chute 12 and slides downwards. The sliding of the limiting shaft 32 is directly guided by the inner side wall of the chute 12.

As shown in fig. 5 and fig. 8 to fig. 9, when some embodiments are adopted, the limiting section 122 is obliquely arranged, one end of the limiting section 122 is connected with the sliding section 121, the other end of the limiting section 122 is provided with a locking position W1, and the locking position W1 is a concave locking groove far away from the sliding section 121. When the tilting device 100 tilts under the action of a driving force, the tilting device 100 makes the limiting shaft 32 enter the limiting section 122 from the sliding section 121, and since the groove depth of the sliding section 121 is smaller than that of the limiting section 122, the end of the limiting shaft 32 moves towards the bottom of the sliding groove 12 along the axial direction, and the end of the limiting shaft 32 always abuts against the bottom of the sliding groove 12, so that the limiting shaft 32 cannot move from the limiting section 122 to the sliding section 121. In this way, after the driving force is removed, the tilting device 100 moves the limiting shaft 32 to the locking position W1 along the limiting section 122 under the action of gravity, and then locks, so that the tilting device 100 can still maintain the tilted state after the load is removed.

It should be noted that, the sliding section 121 and the limiting section 122 are both partial sections of the sliding groove 12, the sliding groove 12 is a groove formed by grooving inward from the side surface of the clip 10 facing the limiting shaft 32, and the groove depth of the sliding groove 12 refers to the vertical distance from the side surface of the clip 10 facing the limiting shaft 32 to the bottom of the sliding groove 12. Correspondingly, the groove depth of the sliding section 121 is the vertical distance from the side surface of the clip 10 facing the limiting shaft 32 to the bottom of the sliding groove 12 corresponding to the sliding section 121, and the groove depth of the limiting section 122 is the vertical distance from the side surface of the clip 10 facing the limiting shaft 32 to the bottom of the sliding groove 12 corresponding to the limiting section 122.

Meanwhile, the unlocking section 123 is connected to a higher end of the limiting section 122, when the tilting device 100 needs to unlock, the tilting device 100 continues tilting under the action of a driving force, so that the limiting shaft 32 is moved to the unlocking section 123 after being separated from the locking position W1, and because the groove depth of the limiting section 122 is smaller than that of the unlocking section 123, the end of the limiting shaft 32 moves towards the bottom of the sliding groove 12 along the axial direction thereof, the end of the limiting shaft 32 always abuts against the bottom of the sliding groove 12, so that the limiting shaft 32 cannot move from the unlocking section 123 to the limiting section 122, and the limiting shaft 32 can generate impact sound after impacting the groove bottom of the unlocking section 123, thereby reminding the outside unlocking action to be completed. In this way, after the unlocking action is completed, the driving force is removed, and the tilting device 100 moves the limiting shaft 32 from the unlocking section 123 to the sliding section 121 under the action of gravity, and the releasing action is completed after the sliding section 121 continues to slide down.

It should be noted that the unlocking section 123 is a partial section of the sliding slot 12, and as described above, the slot depth of the unlocking section 123 is the vertical distance from the side of the clip 10 facing the limiting shaft 32 to the bottom of the sliding slot 12 corresponding to the unlocking section 123.

In summary, in the tilting device 100 of the present application, the sliding groove 12 is disposed on the clip lug 10, so that the limiting shaft 32 is slidably engaged in the sliding groove 12, and the end of the limiting shaft 32 can slide along the axial direction thereof relative to the sliding groove 12. Meanwhile, the groove depth of the sliding section 121 is smaller than that of the limiting section 122, and after the limiting shaft 32 enters the limiting section 122 from the sliding section 121, the end part of the limiting shaft 32 moves to the bottom of the abutting limiting section 122 along the axial direction, so that the tilting device 100 is limited; the groove depth of the limiting section 122 is smaller than that of the unlocking section 123, after the limiting shaft 32 enters the unlocking section 123 from the limiting section 122 under the tilting action of a driving force, the end part of the limiting shaft 32 moves to the bottom of the supporting unlocking section 123 along the axial direction, so that the tilting device 100 is unlocked rapidly, the tilting device 100 can be unlocked only by slightly lifting the tilting device 100, and an additional unlocking switch is not required to be arranged to release the tilting device 100.

Referring to fig. 7, the limiting bracket 30 further includes an elastic member 322, where the elastic member 322 is elastically connected between the limiting shaft 32 and the bracket body 31, and is used for driving the end surface of the limiting shaft 32 to abut against the bottom wall of the chute 12. In an embodiment, two sides of the first end 311 of the bracket body 31 are respectively provided with an extension protrusion 313, and the extension protrusions 313 extend from the first end 311 of the bracket body 31 away from the second end 312 of the bracket body 31. The extending protrusion 313 is provided with a mounting hole 3130, and the limiting shaft 32 is partially accommodated in the mounting hole 3130. The end of the limiting shaft 32 far away from the sliding groove 12 is provided with a supporting plate 323 and an elastic piece 322, and the supporting plate 323 is fixed at the end of the limiting shaft 32 far away from the sliding groove 12. The elastic piece 322 is sleeved on the periphery of the limiting shaft 32, one end of the elastic piece 322 is connected to the bracket body 31, the other end of the elastic piece 322 is elastically propped against and connected to the supporting plate 323, and the elastic piece is used for applying elastic force along the axial direction of the limiting shaft 32 to enable the limiting shaft 32 to elastically reset towards the bottom of the sliding groove 12 along the axial direction of the limiting shaft. It is noted that the elastic member 322 may be a rectangular spring or the like.

Referring to fig. 7, 8 and 9, the limiting section 122 is connected to the unlocking section 123, and a first supporting surface P1 is disposed between the limiting section 122 and the unlocking section 123, and the first supporting surface P1 is used for preventing the limiting shaft 32 from entering the limiting section 122 from the unlocking section 123. In an embodiment, since the groove depth of the limiting section 122 is smaller than the groove depth of the unlocking section 123, a step surface is formed at the connection between the limiting section 122 and the unlocking section 123, and the step surface is the first supporting surface P1. The first supporting surface P1 is disposed substantially perpendicular to the bottom wall of the unlocking section 123, that is, the first supporting surface P1 is substantially parallel to the axial direction of the limiting shaft 32, the limiting shaft 32 slides from the limiting section 122 to pass through the first supporting surface P1 under the action of a driving force, and the limiting shaft 32 slides axially toward the bottom wall of the unlocking section 123 under the action of an elastic force provided by the elastic member 322, so that the limiting shaft 32 is under the abutting action of the first supporting surface P1 and cannot fall back to the limiting section 122 after the driving force is removed.

Referring to fig. 7, 8 and 9, the unlocking section 123 includes a guiding inclined plane P4, the unlocking section 123 and the sliding section 121 are connected by the guiding inclined plane P4, and the guiding inclined plane P4 is used for guiding the limiting shaft 32 from the unlocking section 123 to the sliding section 121. In an embodiment, the guiding inclined plane P4 extends obliquely outward from the unlocking section 123 to the sliding section 121, and the guiding inclined plane P4 is configured to be a plane or a curved surface, so that when the limiting shaft 32 moving to the unlocking section 123 slides down under the gravity action of the tilting device 100, the guiding inclined plane P4 guides the limiting shaft 32 to move from the unlocking section 123 to the sliding section 121 rapidly, so as to realize quick release of the tilting device 100 and fall back.

The guiding inclined plane P4 intersects with the first supporting surface P1, so that it is ensured that the limiting shaft 32 moves to abut against the guiding inclined plane P4 directly after moving to pass through the first supporting surface P1, and the guiding inclined plane P4 guides the limiting shaft 32 to slide downwards rapidly.

Referring to fig. 7, 8 and 9, the sliding section 121 is connected to the limiting section 122, and a second supporting surface P2 is disposed between the sliding section 121 and the limiting section 122, and the second supporting surface P2 is used for preventing the limiting shaft 32 from entering the sliding section 121 from the limiting section 122. In an embodiment, since the groove depth of the limiting section 122 is greater than the groove depth of the sliding section 121, a step surface is formed at the connection between the limiting section 122 and the sliding section 121, i.e. the second supporting surface P2. The second supporting surface P2 is disposed substantially perpendicular to the bottom wall of the limiting section 122, and after the limiting shaft 32 slides from the sliding section 121 to pass through the second supporting surface P2 under the action of a driving force, the limiting shaft 32 slides axially toward the bottom wall of the limiting section 122 under the action of the elastic force provided by the elastic member 322, so that the limiting shaft 32 is under the abutting action of the second supporting surface P2 and cannot fall back to the sliding section 121 after the driving force is removed.

Referring to fig. 7, 8 and 9, a third supporting surface P3 is disposed at an end of the limiting section 122 away from the unlocking section 123, and when the limiting shaft 32 is locked in the limiting section 122, the third supporting surface P3 abuts against the outer peripheral surface of the limiting shaft 32. In one embodiment, the position of the third supporting surface P3 is set as a locking position W1 (shown in fig. 5). The third supporting surface P3 is in a circular arc structure and is adapted to the shape of the bushing 321 of the limiting shaft 32, so that when the limiting shaft 32 moves to the position where the outer peripheral surface of the bushing 321 abuts against the third supporting surface P3, the limiting shaft 32 can be locked just behind the locking position W1, and the limiting shaft 32 is prevented from being separated from the locking position W1 or shaking in the locking position W1 under the action of external force.

Further, the third supporting surface P3 intersects with the second supporting surface P2, and the third supporting surface P3 is smoothly connected with the second supporting surface P2, so that the limiting shaft 32 can slide along the second supporting surface P2 to abut against the third supporting surface P3 after the driving force is removed, and is locked at the locking position W1.

In particular, the third supporting surface P3 is disposed substantially perpendicular to the bottom wall of the limiting section 122, so that the extending direction of the third supporting surface P3 is the same as the axial direction of the limiting shaft 32, the contact area between the third supporting surface P3 and the limiting shaft 32 is increased, and the stability of the limiting shaft 32 at the locking position W1 is improved.

Referring to fig. 7, 8 and 9 again, a first transition wall P5 is disposed on a side of the limiting section 122 away from the sliding section 121, a second transition wall P6 is disposed on a side of the unlocking section 123 away from the sliding section 121, and the first transition wall P5 is connected with the second transition wall P6 for guiding the limiting shaft 32 to move from the limiting section 122 to the unlocking section 123. In an embodiment, the first transition wall P5 is disposed opposite to the second supporting surface P2, and one end of the first transition wall P5 is smoothly connected to the third supporting surface P3. The second transition wall P6 is disposed opposite to the guiding inclined plane P4, and the second transition wall P6 is smoothly connected with one end, far away from the third supporting surface P3, of the first transition wall P5, so that the third supporting surface P3, the first transition wall P5 and the second transition wall P6 are sequentially connected end to end, and therefore the limiting shaft 32 is guided to move along a preset path when the tilting device 100 is unlocked, and unlocking of the tilting device 100 is achieved.

In particular, the first transition wall P5 and the second transition wall P6 are disposed coplanar, and the limiting shaft 32 can smoothly move from the first transition wall P5 to the second transition wall P6, so that the stability of the limiting shaft 32 when entering the unlocking section 123 from the limiting section 122 can be improved.

In this way, when the tilting device 100 is unlocked, the limiting shaft 32 is separated from the third supporting surface P3 under a driving force, and slides towards the unlocking section 123 in close contact with the first transition wall P5, and since the first transition wall P5 is smoothly connected with the second transition wall P6, the limiting shaft 32 can be guided to move to the unlocking section 123 in close contact with the first transition wall P5 and the second transition wall P6, thereby unlocking the tilting device 100.

Referring to fig. 8 and 9 in combination, and referring to fig. 7, the sliding section 121 includes a first side wall P7, and when the limiting shaft 32 moves in the sliding section 121 toward the limiting section 122, the first side wall P7 abuts against an outer peripheral surface of the limiting shaft 32 to guide the limiting shaft 32 to move in the sliding section 121 toward the limiting section 122. In an embodiment, the track of the sliding section 121 is disposed substantially obliquely, and the higher end of the sliding section 121 is located at the side of the lower end of the sliding section 121 near the rotation axis 22, so that the sliding section 121 is inclined from bottom to top toward the position where the rotation axis 22 is located.

The first sidewall P7 is an inner sidewall of the sliding section 121, and the first sidewall P7 is disposed along the extending direction of the sliding section 121 and is disposed at a side of the sliding section 121 away from the rotation shaft 22. In this way, when the tilting device 100 is tilted, the second end 312 of the support body 31 rotates upward about the rotation axis 22, so that the first end 311 of the support body 31 moves upward relative to the rotation axis 22, and the support body 31 also opens relative to the tilting support 20 under the tension of the torsion spring 23 mounted on the rotation axis 22, so that the limiting shaft 32 is forced to open relative to the tilting support 20 along with the opening of the support body 31, i.e. the opening direction of the support body 31 relative to the rotation axis 22 is opposite to the rotation direction of the tilting support 20 relative to the rotation axis 22, so that the limiting shaft 32 always has a tendency to abut outward, and under this tendency, the limiting shaft 32 moves toward the first side wall P7 until the limiting shaft 32 abuts against the first side wall P7. The tilting device 100 continues tilting, the first end 311 of the bracket body 31 continues to move upwards relative to the rotating shaft 22, the limiting shaft 32 slides upwards in the sliding section 121 and clings to the first side wall P7, the limiting shaft 32 is propped by the first side wall P7, stability of the tilting device 100 during tilting is ensured, and shaking is not easy to occur.

Referring to fig. 8 and 9 in combination, and referring to fig. 7, the sliding section 121 includes a second side wall P8, and when the limiting shaft 32 moves away from the unlocking section 123 in the sliding section 121, the second side wall P8 abuts against an outer peripheral surface of the limiting shaft 32 to guide the limiting shaft 32 to move away from the unlocking section 123 in the sliding section 121. In an embodiment, the second sidewall P8 is an inner sidewall of the sliding section 121 and is disposed opposite to the first sidewall P7. The second side wall P8 is disposed along the extending direction of the sliding section 121 and is disposed at a side of the sliding section 121 near the rotation shaft 22. When the tilting device 100 is released, the second end 312 of the bracket body 31 rotates downward around the rotation axis 22, so that the first end 311 of the bracket body 31 moves downward relative to the rotation axis 22, and the bracket body 31 also opens relative to the tilting bracket 20 under the tension of the torsion spring 23 mounted on the rotation axis 22, so that the limiting shaft 32 is forced to open relative to the tilting bracket 20 along with the opening of the bracket body 31, i.e. the opening direction of the bracket body 31 relative to the rotation axis 22 is opposite to the rotation direction of the tilting bracket 20 relative to the rotation axis 22, so that the limiting shaft 32 always has an outward abutment trend, and under this trend, the limiting shaft 32 moves towards the second side wall P8 until the limiting shaft 32 abuts against the second side wall P8. The tilting device 100 continues to fall back under the action of gravity, the first end 311 of the bracket body 31 continues to move downwards relative to the rotating shaft 22, the limiting shaft 32 slides downwards in the sliding section 121 and is clung to the second side wall P8, the second side wall P8 plays a role in propping against the limiting shaft 32, stability of the tilting device 100 during release is ensured, and shaking is not easy to occur.

Referring to fig. 10 and 11 again, the tilting device 100 further includes a driving assembly 40, where the driving assembly 40 is connected to the fixture 1 and the tilting bracket 20, and is used for providing the tilting power of the tilting bracket 20 relative to the fixture 1; illustratively, the fixed end of the drive assembly 40 is rotatably coupled to the clamp 1. In an embodiment, a mounting seat 13 is further disposed between the two clamping ears 10, and the mounting seat 13 is connected to one end of the clamping ears 10 away from the tilting main shaft 11. One end of the driving assembly 40 is mounted on the mounting seat 13, and the other end thereof is connected with the tilting bracket 20, so as to provide a driving force to tilt the tilting bracket 20 around the tilting main shaft 11.

Further, the driving assembly 40 includes a tilting bottom shaft 43, a telescopic mechanism 41 and an actuator 42, the tilting bottom shaft 43 is rotatably disposed at the position of the fixture 1 away from the tilting main shaft 11, one end of the telescopic mechanism 41 is connected to the tilting bottom shaft 43, the other end thereof rotatably abuts against the tilting bracket 20, and the actuator 42 is connected to the telescopic mechanism 41 for driving the telescopic mechanism 41 to stretch. In an embodiment, the axial direction of the tilting bottom shaft 43 is the same as that of the tilting main shaft 11, and one end of the tilting bottom shaft 43 passes through the mounting seat 13 and is rotationally connected with one of the lugs 10, and the other end of the tilting bottom shaft 43 is rotatably mounted in the mounting seat 13. One end of the telescopic mechanism 41 far away from the tilting main shaft 11 is provided for the tilting bottom shaft 43 to pass through, so that the telescopic mechanism 41 can rotate around the axis of the tilting bottom shaft 43, and the telescopic mechanism 41 can synchronously move when the tilting bracket 20 tilts, so that the telescopic mechanism 41 always keeps the abutting action on the tilting bracket 20.

The telescopic mechanism 41 comprises a cylinder 411 and a telescopic rod 412, and the telescopic rod 412 is telescopically arranged in the cylinder 411; illustratively, the telescoping rod 412 abuts against the tilt bracket 20 and is in rotational engagement with the tilt bracket 20. The end of the telescopic rod 412, which is close to the tilting main shaft 11, is located outside the cylinder 411 and is provided with a connecting sleeve 413 at which a connecting shaft 44 is mounted. The connecting shaft 44 is rotatably accommodated in the connecting sleeve 413, the connecting shaft 44 is in the same axial direction as the tilting main shaft 11, and both ends of the connecting shaft 44 penetrate the connecting sleeve 413. One end of the connecting shaft 44 is mounted on the ear plate 21, and the other end is mounted on the tilting bracket 20, so that when the telescopic mechanism 41 drives the tilting bracket 20 to tilt, the telescopic mechanism 41 can rotate around the axis of the connecting shaft 44, and further the telescopic mechanism 41 deflects relative to the tilting bracket 20 so as to be matched with the tilting action of the tilting bracket 20.

The actuator 42 is mounted on the outer side of the telescopic mechanism 41, and is operable in synchronization with the telescopic mechanism 41, and the actuator 42 is used to adjust the telescopic amount of the telescopic rod 412 and further adjust the tilting height of the tilting bracket 20 lifted by the telescopic rod 412.

In particular, when another embodiment is adopted, the driving force may be provided by manpower, and the tilting bracket 20 is driven to act after the tilting bracket 20 is pushed and pulled by manpower.

Referring to fig. 11 again, the telescopic mechanism 41 is configured as a hydraulic telescopic mechanism, and the actuator 42 is configured as an oil pump motor for adjusting the amount of oil in the hydraulic telescopic mechanism to adjust the telescopic length of the hydraulic telescopic mechanism. In an embodiment, the telescopic mechanism 41 is driven by hydraulic pressure, so that the stability of the telescopic mechanism is better, and the tilting device 100 is not easy to shake during the tilting process. The actuator 42 is connected to the telescopic mechanism 41 through a pipe, and can exchange hydraulic oil with the telescopic mechanism 41, so that the amount of oil in the cylinder 411 of the telescopic mechanism 41 is controlled by the actuator 42 to adjust the telescopic distance of the telescopic rod 412 of the telescopic mechanism 41.

Referring to fig. 12 again, the tilting device 100 further includes an angle sensor 50. The angle sensor 50 is coupled to the tilting bracket 20 and the telescopic rod 412, and is used for sensing the relative rotation amount of the telescopic rod 412 and the tilting bracket 20. Illustratively, the angle sensor 50 includes a magnetic portion 51 and a sensing portion 52, the sensing portion 52 moves along with the tilting bracket 20, the magnetic portion 51 moves along with the telescopic rod 412, and the sensing portion 52 is used for sensing a magnetic variable of the magnetic portion 51. For example, referring to fig. 10 again, the tilting device 100 further includes a housing case 60 disposed on the tilting bracket 20, the sensing portion 51 and the magnetic portion 52 are disposed in the housing case 60, the sensing portion 51 is fixed in the housing case 60, and the magnetic portion 52 is rotatably adapted to the housing case 60. In an embodiment, the accommodating housing 60 may be sealed by filling sealant, adding a sealing ring at the opening, and the like. In the embodiment, the angle sensor 50 is arranged inside the tilting bracket 20, so that the appearance is not affected; the induction part 51 and the magnetic part 52 are both arranged in the accommodating shell 60, so that the sealing effect with the cavity is good; further, the relative positions of the sensing portion 51 and the magnetic portion 52 are fixed, so that the angle detection accuracy of the angle sensor 50 is not affected by the mounting.

The tilting angle can be detected by using the angle sensor 50 arranged on the tilting device 100 during the ship moving process, and the tilting control is performed based on the detected tilting angle and the limit condition of the mechanical limit structure (such as the fixture 1 shown in fig. 2); when the angle sensor 50 fails, it cannot be effectively identified whether the tilting angle of the tilting device 100 enters into the limit or exits from the limit, so that the automatic limit protection function cannot be completed through the normal control logic, and if the tilting device 100 continues to execute the tilting instruction, there may be a risk of physically damaging the mechanical limit structure. In one example, as shown in fig. 3, 5, 8, 9 and 12, after the angle sensor 50 fails, it cannot be known which one of the sliding section 121, the limiting section 122 and the unlocking section 123 the tilting device 100 is located; if the tilting device 100 is currently located in the limiting section 122, and the user wants the water propeller 200 to tilt downward, the limiting shaft 32 will collide with the second supporting surface P2 of the limiting section 122, and there is a risk of physically damaging the fixture 1.

Therefore, with reference to fig. 12 and 13, in order to solve the above-mentioned problems, in an embodiment of the present application, a travel switch 90 is disposed on the tilting device 100, and the travel switch 90 is used for detecting the tilting state of the tilting device 100, where the tilting state includes a limited state and a non-limited state; and therefore, a limit protection strategy is provided, under the condition that the angle sensor 50 fails, if a tilting instruction is received, the tilting state of the tilting device 100 detected by the travel switch is obtained, and then the tilting device 100 is controlled to execute corresponding tilting according to the tilting instruction based on the tilting state; the tilting state of the tilting device 100 is known by means of the travel switch 90, so that the accuracy of tilting control is improved, an event that a mechanical limit structure is physically damaged under the condition that the angle sensor 50 fails is avoided, and the limit structure of the tilting device 100 is protected from being damaged. In some embodiments, referring to fig. 13, the tilting device 100 is further provided with a processor 70, a memory 80 and a travel switch 90. The travel switch 90 is used for detecting the tilting state of the tilting device 100, and the tilting state includes a limit state and a non-limit state; memory 80 has stored thereon executable instructions that are executable on processor 70; wherein the steps in the limit protection method provided by the embodiment of the application are implemented when the processor 70 executes the executable instructions. For details of the limit protection method, see the following description.

Illustratively, the processor 70 includes, but is not limited to, a central processing unit (Central Processing Unit, CPU), a digital signal processor (Digital Signal Processor, DSP), an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), or an off-the-shelf programmable gate array (Field-Programmable Gate Array, FPGA), or the like.

By way of example, memory 80 may include at least one type of storage medium including flash memory, hard disk, multimedia card, card memory (e.g., SD or DX memory, etc.), random Access Memory (RAM), static Random Access Memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, optical disk, and the like.

For example, referring to fig. 3 and 14, the travel switch 90 may be installed in the limit bracket 30 so that it can sense in which one of the sliding section 121, the limit section 122, and the unlocking section 123 the limit shaft 32 is. Alternatively, referring to fig. 3, 16 and 17, a part of the travel switch 90 is mounted on the limit bracket 30, and the other part is mounted in the sliding section 121, the limit section 122 and the unlocking section 123, respectively, so that it is possible to sense in which section of the sliding section 121, the limit section 122 and the unlocking section 123 the limit shaft 32 is.

When the limit shaft 32 abuts against the limit section 122, the tilting state detected by the travel switch 90 is a limit state; when the limit shaft 32 abuts against the unlocking section 123 or the sliding section 121, the tilting state detected by the travel switch 90 is an unlimited state.

In one possible implementation, the travel switch 90 includes a magnetic member 91 disposed opposite to each other and an inductive member 92 engaged with the magnetic member 91, one of the magnetic member 91 and the inductive member 92 is disposed on a side of the limiting shaft 32 away from the chute 12, the other is disposed on the bracket body 31, the inductive member 92 includes a first inductive element 921 and a second inductive element 922, and the first inductive element 921 and the second inductive element 922 are disposed at intervals. Wherein the first sensing element 921 and the second sensing element 922 are spaced apart such that the distance between the first sensing element 921 and the second sensing element 922 is different from the magnetic element 91, so that the tilting state of the tilting device can be accurately determined based on the distance; in addition, the first sensing element 921 and the second sensing element 922 are arranged at intervals, so that a placement space can be reserved for components on the first sensing element 921 and the second sensing element 922, and the components are prevented from being damaged due to extrusion when the two sensing elements are attached. When the limiting shaft 32 is in different sections of the sliding section 121, the limiting section 122 and the unlocking section 123, the distance between the magnetic member 91 and the sensing member 92 is different, so that the magnetic field sensed by the sensing member 92 is changed, and the first sensing element 921 and the second sensing element 922 output different electrical signals, so that whether the tilting state of the tilting device is in the limiting state or the non-limiting state can be determined based on the electrical signals output by the first sensing element 921 and the second sensing element 922.

In an example, referring to fig. 14, the magnetic member 91 is disposed on a side of the limiting shaft 32 away from the sliding slot, and the sensing member 92 is disposed on the bracket body 31 for illustration: when the stopper shaft 32 is in different sections of the sliding section 121, the stopper section 122 and the unlocking section 123, the distance between the magnetic member 91 and the first sensing element 921 and the distance between the magnetic member 91 and the second sensing element 922 change, and the magnetic fields sensed by the first sensing element 921 and the second sensing element 922 change, so that the first sensing element 921 and the second sensing element 922 output different electric signals.

Assuming that the magnetic member 91 is close to the sensing member 92, the sensing member 92 outputs an ON signal; when the magnetic member 91 is away from the sensing member 92, the sensing member 92 outputs an OFF signal. Referring to fig. 15, fig. 15 shows the case that the magnetic member 91 is far from or near to the first sensing element 921 and the second sensing element 922, and the case that the first sensing element 921 and the second sensing element 922 output signals when the limiting shaft 32 is in different sections of the sliding section 121, the limiting section 122 and the unlocking section 123. Referring to fig. 15 (1), when the limiting shaft 32 abuts against the sliding section 121, the magnetic element 91 is relatively close to the first sensing element 921 and the second sensing element 922, and the electric signals output by the first sensing element 921 and the second sensing element 922 are ON and off respectively. Referring to fig. 15 (2), when the limiting shaft 32 abuts against the limiting section 122, the distance between the magnetic element 91 and the first sensing element 921 is relatively close, but the distance between the magnetic element and the second sensing element 922 is relatively far, and the electric signals output by the first sensing element 921 and the second sensing element 922 are ON and OFF, respectively. Referring to fig. 15 (3), when the limiting shaft 32 abuts against the unlocking section 123, the magnetic member 91 is far from the first sensing element 921 and the second sensing element 922, and the electric signals output by the first sensing element 921 and the second sensing element 922 are OFF and OFF respectively.

Of course, when the magnetic member 91 approaches the sensing member 92, the sensing member 92 may output an OFF signal; when the magnetic member 91 is away from the sensing member 92, the sensing member 92 outputs an ON signal. When the limiting shaft 32 abuts against the sliding section 121, the electrical signals output by the first sensing element 921 and the second sensing element 922 are OFF and OFF, respectively. When the limiting shaft 32 abuts against the limiting section 122, the electric signals output by the first sensing element 921 and the second sensing element 922 are OFF and ON, respectively. When the limiting shaft 32 abuts against the unlocking section 123, the electric signals output by the first sensing element 921 and the second sensing element 922 are ON and ON respectively.

In another possible implementation, referring to fig. 16 and 17, the travel switch 90 includes a magnet 93 disposed opposite to each other and three inductive switches 94 cooperating with the magnet 93, the magnet 93 is disposed on the limit bracket 30, and the three inductive switches 94 are disposed in three sections of the chute 12 respectively. When the limit shaft 32 is in different sections of the sliding section 121, the limit section 122 and the unlocking section 123, the magnet 93 is close to different inductive switches 94, and when the magnet 93 is close to one of the inductive switches 94, the contacts inside the inductive switches 94 attract each other under the action of the magnetic field of the magnet 93, so that the inductive circuit inside the inductive switch 94 is in an on state. That is, it is possible to determine which one of the sliding section 121, the limiting section 122, and the unlocking section 123 the limiting shaft 32 is in by detecting the on condition of the three sensing switches 94, thereby determining whether the tilting state of the tilting device 100 is in the limiting state or the non-limiting state.

Fig. 18 is a schematic flow chart of a limit protection method according to an embodiment of the application. The method is applied to the tilting device in any of the embodiments. The tilting device comprises an angle sensor and a travel switch, wherein the angle sensor is used for detecting the tilting angle of the tilting device, the travel switch is used for detecting the tilting state of the tilting device, and the tilting state comprises a limiting state and a non-limiting state. It will be understood by those skilled in the art that, in the limit protection method provided by the embodiment of the present application, the same element is indicated in the case that the names of the elements in the above-mentioned water area movable device, the water area propeller and the raising device are the same. The limit protection method comprises the following steps:

in S101, if the tilting command is received in the case where the angle sensor fails, the tilting state of the tilting device detected by the travel switch is obtained.

In S102, based on the tilting state, the tilting device is controlled to execute corresponding tilting according to the tilting instruction. According to the embodiment, the scheme of adding the travel switch in the tilting device is realized, the tilting control based on the indication of the travel switch can be realized under the condition that the angle sensor fails, the accuracy of the tilting control is improved, the occurrence of an event that a mechanical limit structure is physically damaged under the condition that the angle sensor fails is avoided, and the limit structure of the tilting device is protected from being damaged.

In some embodiments, the angle sensor failure includes: the angle sensor does not output the tilting angle within a preset time. The preset duration can be specifically set according to the actual application scenario, and the embodiment does not limit the specific duration. For example, in a normal working condition, the angle sensor outputs a tilting angle every 100ms, and if none of the angle sensors outputs a tilting angle within 1s, the angle sensor is judged to be invalid.

In other embodiments, the angle sensor failure includes: the tilting angle output by the angle sensor does not accord with the preset angle condition. Exemplary, the tilting angle output by the angle sensor does not meet the preset angle condition includes any one of the following: (1) The calibration zero point of the angle sensor is located outside a preset range; (2) The output value of the angle sensor is smaller than the calibration zero point, and the difference value between the output value and the calibration zero point exceeds a first threshold value; (3) The output value of the angle sensor is larger than the calibration zero point, and the difference value between the output value and the calibration zero point is larger than the second threshold value.

For the first case, for example, when the tilting device is tilted downward to the lowest position, the value output by the angle sensor depends on the mounting posture of the angle sensor. For example, for the tilting device a and the tilting device B, when both tilting devices are at the lowest position (i.e., zero point), the values output by the angle sensor may be 10 °, 20 °,10 °, 20 ° respectively, that is, the calibration zero points of the tilting device a and the tilting device B respectively. The processor typically pre-stores the angle data of the calibration zero point, and at the time of the first burning, the calibration zero point is set to a value beyond the angle range sensed by the angle sensor, for example, 0xFFFFFFFF (corresponding to 65535), which can be used to detect whether the angle sensor is calibrated. Under the normal calibration condition, the angle data of the calibration zero point is in the range of 0-360 degrees (corresponding to 0-4096 degrees), and if the calibration zero point is detected to be 65535, namely to be positioned outside 0-4096 degrees, the angle sensor can be judged to be not calibrated, namely the angle sensor fails. It can be understood that 0 ° to 360 ° are one of the illustrated cases, and the preset range can be specifically set according to the actual application scenario, which is not limited in this embodiment.

For the second case, the tilting stroke of the tilting device is fixed, and the calibration zero point of the angle sensor indicates the lowest position of the tilting device. The first threshold may be determined based on an error parameter of the angle sensor. For example, if the first threshold is an error value of the angle sensor, and the output value of the angle sensor is smaller than the calibration zero point, and the difference between the output value and the calibration zero point exceeds the error value of the angle sensor, it can be determined that the angle sensor fails. The error values of the different angle sensors are different, and the specific setting can be carried out according to the actual model of the angle sensor.

For the third case, the tilting stroke of the tilting device is fixed, and the calibration zero point of the angle sensor indicates the lowest position of the tilting device. The second threshold value can be determined according to the tilting stroke of the tilting device and the error parameter of the angle sensor. For example, if the output value of the angle sensor is greater than the calibration zero point, and the difference between the output value and the calibration zero point is greater than the sum of the tilting stroke of the tilting device and the error value of the angle sensor, it may be determined that the angle sensor fails.

Under the condition that the failure of the angle sensor is determined, the tilting device can detect the tilting state of the tilting device by using the travel switch.

In one possible implementation manner, the travel switch comprises a magnetic part and an induction part matched with the magnetic part, wherein the magnetic part and the induction part are oppositely arranged, one of the magnetic part and the induction part is arranged on one side of the limiting shaft far away from the sliding groove, the other is arranged on the bracket body, and the induction part comprises a first induction element and a second induction element. Referring to fig. 14 and 15, when the limiting shaft 32 is in different sections of the sliding section 121, the limiting section 122 and the unlocking section 123, the distance between the magnetic member 91 and the sensing member 92 is different, so that the magnetic field sensed by the sensing member 92 is changed, and the first sensing element 921 and the second sensing element 922 output different electric signals.

Therefore, the tilting device can acquire the first signal output by the first sensing element and the second signal output by the second sensing element, and then determine the tilting state according to the combination condition of the first signal and the second signal. For example, it may be determined, according to the combination of the first signal and the second signal, which section of the sliding section, the limiting section, and the unlocking section the limiting shaft abuts against, and if the limiting shaft abuts against the limiting section, the cocking state is the limiting state; if the limiting shaft is abutted with the unlocking section or the sliding section, the tilting state is an unlimiting state.

For example, referring to fig. 15, if the first signal and the second signal are ON and ON respectively, the limiting shaft is abutted to the sliding section; if the first signal and the second signal are respectively ON and OFF, the limiting shaft is in abutting connection with the limiting section; if the first signal and the second signal are OFF and OFF respectively, the limit shaft is in contact with the unlocking section.

In another possible implementation manner, the travel switch comprises a magnet and three induction switches, wherein the magnet and the three induction switches are oppositely arranged and matched with the magnet, the magnet is arranged on the limit bracket, and the three induction switches are respectively arranged in three sections of the chute. Referring to fig. 16 and 17, when the limit shaft 32 is in different sections of the sliding section 121, the limit section 122 and the unlocking section 123 in the sliding slot, the magnet 93 approaches different inductive switches 94, and when the magnet 93 approaches one of the inductive switches 94, the contacts inside the inductive switches 94 attract each other under the magnetic field of the magnet 93, so that the inductive circuit inside the inductive switch 94 is in an on state.

Therefore, the tilting device can acquire three signals output by the three inductive switches; and determining the tilting state according to the three signals. For example, the cocking device may determine which of the three signals is a circuit-on signal, thereby determining which of the sliding section, the limit section, and the unlocking section the limit shaft is in abutment with. If the limiting shaft is abutted with the limiting section, the tilting state is a limiting state; if the limiting shaft is abutted with the unlocking section or the sliding section, the tilting state is an unlimiting state.

In some embodiments, after obtaining the tilting state of the tilting device detected by the travel switch, the tilting device may control the tilting device to perform corresponding tilting according to the tilting instruction based on the tilting state.

In a first possible implementation manner, if the tilting state is the limit state, that is, the limit shaft of the tilting device abuts against the limit section; the tilting instructions comprise upward tilting instructions, and the execution of the upward tilting instructions can enable the limiting shaft of the tilting device to move from the limiting section to the unlocking section, so that the limiting risk of physical damage is avoided in the process. Thus, S102 in fig. 18 includes: based on the limiting state, the tilting device is controlled to tilt up according to the tilting up instruction.

In a second possible implementation manner, if the tilting state is the limit state, that is, the limit shaft of the tilting device abuts against the limit section; the tilting instruction comprises a downward tilting instruction, and because the limiting shaft of the tilting device is positioned in the limiting section, the downward tilting instruction can enable the limiting shaft of the tilting device to move from the limiting section to the sliding section, and a second supporting surface is arranged between the sliding section and the limiting section and used for preventing the limiting shaft from entering the sliding section from the limiting section, so that the limiting risk of physical damage exists. Thus, S102 in fig. 18 includes: based on the limit state, controlling the tilting device to tilt upwards, and acquiring the tilting state of the tilting device detected by the travel switch; when the tilting state is changed into the non-limiting state, the tilting device is controlled to tilt downwards according to the tilting-downwards instruction. According to the embodiment, when the downward tilting command is received in the limiting state, the release limiting is realized by forcedly tilting upward, so that the limiting structure of the tilting device is prevented from being damaged.

Further, the limit protection method further comprises the following steps: during the upward tilting period of the tilting control device, if a control instruction is received, determining the control level of the control instruction; if the control level of the control instruction is higher than that of the downward warping instruction, the warping control device stops warping upward and executes the control instruction; if the control level of the control command is lower than that of the downward tilting command, the control command is shielded, and the tilting device is continuously controlled to tilt upward.

For example, control commands having a higher control level than the control of the warp command include, but are not limited to, a shutdown command, a stop warp command, and the like.

In a third possible implementation, if the tilting state is an unqualified state, i.e. the limiting shaft of the tilting device abuts against the unlocking section or the sliding section, in this case there is no risk of physical damage limitation, whether an upward tilting command or a downward tilting command is executed. Therefore, if the cocking state is the non-limit state and the cocking instruction is the up-cocking instruction, S102 in fig. 18 includes: based on the non-limiting state, the tilting device is controlled to tilt up according to the tilting up instruction. If the cocking state is the non-limiting state and the cocking instruction is the downward cocking instruction, S102 in fig. 18 includes: based on the non-limiting state, the tilting device is controlled to tilt downwards according to the tilting command.

In some embodiments, the limit protection method further comprises: under the condition that the angle sensor fails, if a tilting instruction is received, a source mechanism for sending the tilting instruction can be obtained; if the source mechanism meets the preset conditions, controlling the tilting device to tilt according to the tilting instruction; otherwise, shielding the warping instruction.

Illustratively, the source mechanisms of the warp command are typically 4 of the following: (1) a key disposed on the cocking device; (2) a key on a tiller connected with a water area propeller; (3) The display screen is arranged on the movable body of the movable equipment in the water area; (4) A key on a remote operation box which is in communication connection with the water area propeller, wherein the remote operation box is arranged on a movable body of movable equipment in the water area; (5) The water area can move the mobile terminal of the equipment, such as the key on the mobile phone. The display screen and the remote control box are generally arranged at the head part of the movable body (such as a control room of the bow), and the water area propeller is generally arranged at the tail part of the movable body, and the distance between the display screen and the remote control box is relatively long; the mobile terminal is held by the user, the position of the user is random, and the mobile terminal is not necessarily in the water area propeller; under the condition that the angle sensor fails, if the tilting instruction is from a display screen, a remote operation box or a mobile terminal, the tilting state of the water area propeller is not easy to observe by a user. Therefore, the preset condition may be that the source mechanism that issues the warping instruction is a white list, and the source mechanism belonging to the white list includes: (1) a key disposed on the cocking device; (2) a key on a tiller connected to a water propeller. The distance between the source mechanism belonging to the white list and the water area propeller is relatively short, and under the condition, a user can intuitively observe the tilting state of the water area propeller so as to timely layout related countermeasures, thereby being beneficial to improving the safety. Of course, for the warping instruction of the source mechanism belonging to the white list, the method may be executed according to the limit protection method provided by the embodiment of the present application.

In some embodiments, the mechanical structure of the tilting device is further coated with a limit display flag for indicating a tilting state of the tilting device, the tilting state including a limit state and a non-limit state. Illustratively, the limit display indicia includes a first display indicia and a second display indicia; the first display mark indicates that the tilting device is in a limiting state, and the second display mark indicates that the tilting device is in a releasing limiting state. As the limit shaft of the cocking device is in different ones of the limit section, the unlock section, or the slide section, the cocking device is pointed at different display signs. Taking fig. 3, 5, 8 and 9 as an example, when the limiting shaft 32 of the tilting device 100 is in the limiting section 122, the tilting device 100 points to the first display mark; when the limiting shaft 32 of the tilting device 100 is in the unlocking section 123 or the sliding section 121, the tilting device 100 is directed to the second display mark. Therefore, a user can manually confirm whether the machine is in a limiting state according to the limiting display mark.

The various technical features of the above embodiments may be arbitrarily combined, so long as there is no conflict or contradiction between the combinations of the features, and therefore, the arbitrary combination of the various technical features of the above embodiments also falls within the scope of the disclosure of the present specification.
