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 propeller 200, wherein the propeller 200 is movably connected to the movable body 301. The propeller 200 acts as a power supply for the water movable apparatus 300, which is capable of changing its posture relative to the movable body 301 to place it under the water surface when it is required to use the propeller 200, thereby providing an impetus for the movement of the movable body 301. When the propeller 200 is not required to be used, it is placed above the water surface to reduce resistance to the water flow to which the movable body 301 is subjected when it moves.

The water area movable device 300 of the present 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, etc., or may be devices capable of moving in a water area such as a water area inspection device, a water area management device, a water area environment monitoring device, etc., which is not limited in this aspect of the present application. 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 propeller 200, which includes a main machine 201 and a tilting device 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 propeller 200 is not required to be used, the host 201 is lifted above the water surface after the tilting bracket 20 is tilted, and when the propeller 200 is required to be used, the host 201 is returned below the water surface after the tilting bracket 20 is released.

The above-mentioned tilting device 100 may be the tilting device 100 in any of the following embodiments.

As shown in fig. 3 to 5, the present embodiment provides a tilting device 100, which includes a fixture 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 with the tilting main shaft 11 and configured to tilt relative to the fixture 1, and the tilting bracket 20 is used for connection with a host. 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 lifting support 20 lifts under the action of a driving force, the driving force can be provided by a power device or manpower and is applied to the lifting support 20, so that the lifting support 20 can lift relative to the hull, the driving force appearing in the following description is equivalent to the driving force at present, and the lifting support 20 drives the support body 31 to move along with the lifting support 20 through the rotating shaft 22 fixedly connected with the lifting support 20. 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.

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.

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.

One end of the tilting power assembly 40 is mounted on the mounting seat 13, and the other end of the tilting power assembly 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.

Any of the following embodiments may be combined with any of the above embodiments, in combination with reference to the following description and the accompanying drawings.

In the present application, based on any of the above embodiments, referring to fig. 12, the tilting device 100 may further include a sensor assembly 50, where the sensor assembly 50 includes a magnetic member 51 and an inductive member 52, one of the magnetic member 51 and the inductive member 52 is disposed on the limiting shaft 32, the other is disposed on the bracket body 31, and the inductive member 52 includes at least two inductive elements 520 for respectively cooperating with the magnetic member 51 to output an electrical signal; the electrical signal is used to indicate the abutment position of the limit shaft 32 with the chute 12.

In the drawing, the solid line represents one connection relationship, such as that the magnetic member 51 is connected with the limiting shaft 32, the sensing member 52 is connected with the bracket body 31, and the dotted line represents another connection relationship, such as that the magnetic member 51 is connected with the bracket body 31, the sensing member 52 is connected with the limiting shaft 32, and both connection modes can realize the function of the sensor assembly 50, specifically according to the actual requirement.

For the convenience of understanding the principle of the sensor assembly 50 of the present application, reference may be made to fig. 13, which is a schematic diagram of an exemplary sensing element 52 and a magnetic element 51, wherein the magnetic field generated by the magnetic element 51 is simplified to be a magnetic field 511, and the magnetic field 511 is mainly used to illustrate the influence of the movement of the magnetic element 51 on the magnetic field range, and the specific shape and size of the magnetic field are subject to practical requirements. The sensing element 52 includes a first sensing element 521 and a second sensing element 522, and a fixed distance may be between the first sensing element 521 and the second sensing element 522, and according to the figure, the case a, the case b, and the case c respectively represent three cases from the near to the far between the magnetic element 51 and the sensing element 52.

In this embodiment it may be assumed that the hall element senses a sufficient magnetic force to output an a signal, and otherwise a B signal. In case a, the first sensing element 521 and the second sensing element 522 fall within the range of the magnetic field 1011 and both output a signal, the signal output by the sensing element 52 may be expressed as (a, a); in case B, the magnetic force sensed by the second sensing element 522 is insufficient, and thus the B signal is outputted, the signal outputted from the sensing element 52 may be expressed as (a, B); similarly, in case c, the signal output by sensing element 52 may be denoted as (B, B).

In the above embodiment, the three signals (a, a), (a, B), (B, B) may refer to three tilt angles or angle ranges, respectively.

In another embodiment, the sensing element 52 may output a continuously variable signal, which may be understood as that as the distance between the magnetic element 51 and the sensing element 52 decreases, the strength of the signal output by the sensing element 52 increases (or decreases), and the distance between the magnetic element 51 and the sensing element 52 corresponds to the tilting angle, that is, there is a continuously variable correspondence between the tilting angle and the strength of the signal.

Through the above scheme, the diversity of the magnetic piece 51 and the sensing piece 52 is applied to the tilting device 100, and the included angle between the fixture 1 and the tilting bracket 20 is converted into the distance between the magnetic piece 51 and the sensing piece 52 through a certain connection relationship, so that when the angle changes, the signal output by the sensing piece 52 also changes. The magnetic member 51 and the sensing member 52 do not move relatively in the radial direction or the circumferential direction, which is advantageous for improving the detection accuracy of the sensor assembly 50.

In the present application, the type of the signal output by the sensing element 52 may be an analog signal such as a voltage signal or a current signal, or may be a digital signal in which the analog signal is converted, such as a/B and 0/1 of the above embodiment, which may be used in an automatic/semi-automatic circuit.

Specifically, in the present application, referring to fig. 5 and 14a, the magnetic member 51 may be disposed at an end of the limiting shaft 32 far from the chute 12, the sensing member 52 is disposed on the bracket body 31, and opposite to the magnetic member 51, the magnetic member 51 slides relative to the sensing member 52 along a direction parallel to the tilting main shaft 11 under the driving of the limiting shaft 32. The sensing element 52 for outputting signals is fixed on the bracket body 31, which is more beneficial to the wiring connection of the sensing element 52, for example, the cable of the sensing element 52 can be attached to the bracket body 31.

Or referring to fig. 14b, the sensing element 52 may be disposed at an end of the limiting shaft 32 far away from the chute 12, and the magnetic element 51 is disposed on the bracket body 31, and opposite to the sensing element 52, the sensing element 52 slides relative to the magnetic element 51 along a direction parallel to the tilting main shaft 11 under the driving of the limiting shaft 32. The sensing piece 52 is arranged on the limiting shaft, the limiting shaft can serve as a protective shell, and the sensing piece 52 can be prevented from being exposed and damaged without an additional structure.

The end portion of the stopper shaft 32 may be located inside the end portion (shown in fig. 14a or 14 b) or outside the end portion (not shown).

In fig. 14a and 14b, the direction of the rotation axis 22 shown in the drawings may be substituted for the direction of the tilting main shaft 11, since the rotation axis 22 is arranged in parallel with the axis of the tilting main shaft 11. It can be understood that, in order to adapt to the structure of the bracket body 31 or the limiting shaft 32, the adapting structure, the extending structure, etc. can be appropriately increased or decreased when the device is fixedly connected with the bracket body 31 or the limiting shaft 32, or the cover structure is added for aesthetic property, etc. all fall within the protection scope of the present application when the implementation of the present application is not affected.

Based on the above-mentioned scheme, in order to make the sensing piece 52 more accurately sense the magnetic change, a plurality of sensing pieces 52 may be sequentially arranged along the direction parallel to the tilting main axis 11.

The plurality of sensing elements 520 may be understood as at least two, when one sensing element 520 is capable of outputting two signals: if the sensing element 520 senses the magnetic element 51 as being triggered (or the sensing element 520 senses the magnetic element 51 as being triggered when the magnetic field strength is high), the sensing element 51 is not sensed as being triggered (or the sensing element 520 senses the magnetic element 51 as being triggered when the magnetic field strength is low), and the sensing elements 520 are sequentially arranged along one direction, so that when the sensing elements 520 are N (N is greater than or equal to 2, N is a natural number), a plurality of triggering conditions exist, and the sensing element 52 can output signals in various combination forms. The number of sensing elements 520 included in the sensing element 52 may be selected appropriately according to the required measurement accuracy, and variations in the number of sensing elements 520 should not affect the implementation of the present solution, and should fall within the scope of the present application.

In order to adapt to the processing technology of the sensing elements 520, enough wiring space is reserved, and two adjacent sensing elements 520 can be arranged at intervals.

Through making two adjacent sensing element 520 interval setting, when being convenient for assemble sensing element 520, also can be used to prevent to appear because the change is unobvious in the short distance so that two sensing element 520 are the same at the signal of same moment output, also can guarantee that two adjacent sensing element 520 are different at the magnetic field intensity of same moment sensing.

Referring to fig. 5, on the basis of the scheme having the chute 12, the chute 12 includes a sliding section 121, a limiting section 122, and an unlocking section 123, the sliding section 121 having a groove depth smaller than that of the limiting section 122, and the limiting section 122 having a groove depth smaller than that of the unlocking section 123;

one end of the limiting section 122 is set to be 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.

On this basis, the number of the sensing elements 520 may include two, and two electrical signals output by the two sensing elements 520 are used to indicate the abutting section of the limiting shaft 32 and the chute 12.

Three different signals in combination can be output through the two sensing elements 520, and the three abutting sections of the sliding section 121, the limiting section 122 and the unlocking section 123 can be respectively corresponding.

As can be seen from fig. 3, 4, 5 and 12, when the included angle between the fixture 1 and the tilting bracket 20 increases, the limiting shaft 32 slides sequentially through three abutment sections, i.e. the sliding section 121, the limiting section 122 and the unlocking section 123 shown in fig. 5, and the three abutment sections have different groove depths, so that the limiting shaft 32 moves along the axial direction (the axial direction is parallel to the axial direction of the tilting main shaft 11), and the distance between the magnetic member 51 and the sensing member 52 is changed.

For ease of understanding, fig. 5 may be combined with fig. 13 to obtain fig. 15, in which fig. 15 illustrates that the sensing element 52 includes the first sensing element 521 and the second sensing element 522, the solid line in the drawing may represent the current position, and the dotted line represents the position after sliding at a certain moment, and it may be seen that the limiting shaft 32 slides along three abutting sections on the fixture 1, and when the sections with different depths are abutted, for example, from the sliding section 121 to the limiting section 122, the magnetic element 51 moves axially along with the limiting shaft 32, and displacement corresponding to the depth difference occurs between the magnetic element 51 and the sensing element 52 because the sensing element 52 fixed to the bracket body 31 cannot move. Similarly, when the magnetic member 51 is connected to the holder body 31 and the sensing member 52 is connected to the limiting shaft 32, the same displacement can be generated, so that the sensing member 52 outputs different signals as shown in the figure.

In the present application, when the number of sensing elements 520 included in the sensing element 52 is increased, the number of corresponding abutment sections is increased, and as can be seen from fig. 15, each time the limiting shaft 32 slides to an abutment surface with a different depth, the sensing element 52 outputs a different signal, and the number of abutment sections is consistent with the type of signal to be outputted.

Hereinabove, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those of ordinary skill in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the application without departing from the scope thereof. Such modifications and substitutions are intended to be included within the scope of the present application.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the application.
