[0037] See also Figure 1 and Figure 2 , Figure 5 and Figure 6 , Figure 7 or Figure 8 The tilting device 100 provided in the embodiment of the present application includes a fixed bracket 10, a rotating bracket 20, a power mechanism 30 and a first stopper 40. The rotating bracket 20 is rotatably mounted on the fixed bracket 10. The power mechanism 30 includes a first end 31 and a second end 33 relative to each other, a first connecting mechanism 60 is arranged between the first end 31 of the power mechanism and the fixed bracket 10, and a second connecting mechanism 70 is arranged between the second end 33 of the power mechanism and the rotating bracket 20. The power mechanism 30 drives the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10 through the first connecting mechanism 60 and the second connecting mechanism 70. The first stopper 40 is arranged on at least one of the first connecting mechanism 60 and the second connecting mechanism 70, and is used to limit the first connecting mechanism 60 to remain relatively fixed with the fixed bracket 10, and / or limit the second connecting mechanism 70 to remain relatively fixed with the rotating bracket 20. In the case where the tilting device 100 is subjected to an impact force, the first stopper 40 is also used to release the restriction on at least one of the first connecting mechanism 60 and the second connecting mechanism 70, so as to allow the rotating bracket 20 to rotate relative to the fixed bracket 10. The rotation range is increased. In the present application, the impact force exerted on the lifting device 100 is mainly formed by the impact force generated by the propeller 200 being hindered in the propulsion direction during the propulsion process, and is fed back to the lifting device 100 along the entire power transmission path from the impact position to the lifting device 100.

[0038] In some embodiments, the fixed bracket 10 may include two side walls 17, the side walls 17 of the two fixed brackets are arranged at intervals, the rotating bracket 20 and the power mechanism 30 are both arranged between the side walls 17 of the two fixed brackets, and the power mechanism 30 can drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10 through the first connecting mechanism 60 and the second connecting mechanism 70.

[0039] In some embodiments, the first stopper 40 may be configured on the first connection mechanism 60, that is, the first stopper 40 cooperates with the first connection mechanism 60, so that the first stopper 40 can limit the first connection mechanism 60 to remain relatively fixed to the fixed bracket 10, such as Figure 1 and Figure 2 As shown, or as Figure 5 and Figure 6 At this time, when the lifting device 100 is subjected to an impact force, the first limiter 40 can release the restriction on the first connection mechanism 60 to allow the rotating bracket 20 to rotate relative to the fixed bracket 10 to increase the rotation range. In other embodiments, the first limiter 40 can be configured on the second connection mechanism 70, that is, the first limiter 40 cooperates with the second connection mechanism 70, so that the first limiter 40 can limit the second connection mechanism 70 to remain relatively fixed with the rotating bracket 20, such as Figure 7 As shown, or as Fig. 9 As shown. At this time, when the tilting device 100 is subjected to an impact force, the first stopper 40 can release the restriction on the second connection mechanism 70 to allow the rotation range of the rotating bracket 20 to increase relative to the fixed bracket 10. In some further embodiments, the first stopper 40 can be configured on the first connection mechanism 60 and the second connection mechanism 70, that is, the first stopper 40 can include two, and the two first stoppers 40 are respectively matched with the first connection mechanism 60 and the second connection mechanism 70, so that the first stopper 40 matched with the first connection mechanism 60 can limit the first connection mechanism 60 to remain relatively fixed with the fixed bracket 10, and the first stopper 40 matched with the second connection mechanism 70 can limit the second connection mechanism 70 to remain relatively fixed with the rotating bracket 20. At this time, when the tilting device 100 is subjected to an impact force, the first stopper 40 matched with the first connection mechanism 60 can release the restriction on the first connection mechanism 60, and the first stopper 40 matched with the second connection mechanism 70 can release the restriction on the second connection mechanism 70, so that the rotation range of the rotating bracket 20 to rotate relative to the fixed bracket 10 can increase.

[0040] In some embodiments, the power mechanism 30 may include a telescopic assembly 35. The telescopic assembly 35 includes a main body 351 and a telescopic rod 353, the telescopic rod 353 is telescopically mounted on the main body 351, the first connecting mechanism 60 is disposed between the main body 351 and the fixed bracket 10, and the first connecting mechanism 60 and the main body 351 form a rotation pair. The second connecting mechanism 70 is disposed between the telescopic rod 353 and the rotating bracket 20, and the second connecting mechanism 70 and the telescopic rod 353 form a rotation pair. It should be noted that in some embodiments, the telescopic assembly 35 may be a hydraulic cylinder or a pneumatic cylinder.

[0041] Among them, a kinematic pair is a movable connection between two components that are in direct contact and can produce relative rotation. The points, lines, surfaces and other elements on the two components that participate in the contact and constitute the kinematic pair are called kinematic pair elements. It should be noted that in some embodiments, the kinematic pair includes but is not limited to a translation pair, a rotation pair and a screw pair.

[0042] See also Figure 2 , Figure 6 , Figure 7 and Fig. 9 In the embodiment of the present application, the first connecting mechanism 60 is arranged between the main body 351 and the fixed bracket 10, and the first connecting mechanism 60 and the main body 351 form a revolute pair, that is, the first connecting mechanism 60 and the main body 351 are in direct contact and can generate relative rotation. Specifically, in some embodiments, the first connecting mechanism 60 may include a first shaft 61, the first shaft 61 passes through the first end 31 of the power mechanism and can rotate relative to the first end 31 of the power mechanism, that is, the first shaft 61 and the main body 351 are rotatably connected. Among them, the two components that form the revolute pair between the first connecting mechanism 60 and the main body 351 can be: the first shaft 61 and the main body 351. The revolute pair element can be: the outer surface of the first shaft 61 and the surface on the main body 351 that contacts the outer surface of the first shaft 61. The second connecting mechanism 70 is arranged between the telescopic rod 353 and the rotating bracket 20, and the second connecting mechanism 70 and the telescopic rod 353 form a revolute pair, that is, the second connecting mechanism 70 and the telescopic rod 353 are in direct contact and can generate relative rotation. Specifically, in some embodiments, the second connection mechanism 70 may include a second shaft 71, which passes through the second end 33 of the power mechanism and can rotate relative to the second end 33 of the power mechanism, that is, the second shaft 71 is rotatably connected to the telescopic rod 353. Among them, the two components forming the rotation pair of the second connection mechanism 70 and the telescopic rod 353 may be: the second shaft 71 and the telescopic rod 353. The rotation pair elements may be: the outer surface of the second shaft 71 and the surface of the telescopic rod 353 that contacts the outer surface of the second shaft 71.

[0043] To sum up, the first connecting mechanism 60 and the main body 351 form a rotating pair, and the second connecting mechanism 70 and the telescopic rod 353 form a rotating pair, thereby, the first end 31 of the power mechanism can rotate relative to the fixed bracket 10, and the second end 33 of the power mechanism can rotate relative to the rotating bracket 20, so that the power mechanism 30 can drive the rotating bracket 20 to rotate relative to the fixed bracket 10 through the first connecting mechanism 60 and the second connecting mechanism 70, thereby realizing the tilting of the rotating bracket 20.

[0044] Please combine Fig.11 It can be understood that the tilting device 100 can be applied to the propeller 200. Among them, the propeller 200 includes a propulsion state or a tilted state. The propulsion state means that the propeller 215 of the propeller 200 is located underwater and can generate power to drive the hull 1001 of the movable device 1000 in the water area to move. The tilted state refers to tilting the propeller 200 (part of the structure) to avoid obstacles or leave the water surface. It should be noted that when the propeller 200 is tilted to avoid obstacles, the propeller 215 of the propeller 200 may still be located underwater, or the propeller 215 of the propeller 200 may completely leave the water surface. When the propeller 215 of the propeller 200 completely leaves the water surface, the greater the angle at which the propeller 200 is tilted, the farther the propeller 215 is from the water surface. When the propeller 200 is in the propulsion state, if the propeller 200 is subjected to an impact force (for example, the impact force generated by the collision between the propeller 200 and an obstacle), and the propeller 200 has not been transformed into the warped state, the propeller 200 is easily deformed and damaged under the impact force. Therefore, in this embodiment, one end of the telescopic rod 353 is located in the main body 351, and the other end is connected to the rotating bracket 20 through the second connecting mechanism 70. When the propeller 200 is subjected to an impact force, the telescopic rod 353 can be extended from the main body 351 to push the rotating bracket 20 to rotate relative to the fixed bracket 10, so that the propeller 200 is transformed into the warped state to avoid obstacles and prevent the propeller 200 from being damaged by the impact force.

[0045] Specifically, the impact force on the propeller 200 may be: the impact force on the propeller 200 when it collides with an obstacle; the impact force on the propeller 200 may also be: the impact force on the propeller 200 when it reaches a shallow beach; the impact force on the propeller 200 may also be: the interference force of underwater organisms on the propeller 200, etc. In addition, when the propeller 200 is not needed, the lifting device 100 can drive the propeller 200 to achieve lifting, thereby preventing the propeller 200 from being immersed in water for a long time, resulting in damage to the propeller 200 or shortening its life.

[0046] Furthermore, in some embodiments, the rotating bracket 20 is connected to the main unit of the propeller 200, so that when the power mechanism 30 drives the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10, the main unit of the propeller 200 can tilt together with the rotating bracket 20. Therefore, when the main unit of the propeller 200 is subjected to an impact force, the impact force can be transmitted to the power mechanism 30 and the fixed bracket 10 through the rotating bracket 20. If the tilting device is connected internally by a rigid structure, the tilting device and the propeller will be damaged under the impact force, resulting in failure of the tilting and affecting the normal operation of the tilting device and the propeller. In the embodiment of the present application, when the lifting device 100 is subjected to an impact force, the first limit member 40 can release the restriction on at least one of the first connecting mechanism 60 and the second connecting mechanism 70 to allow the rotating bracket 20 to rotate relative to the fixed bracket 10. The rotation range is increased, thereby achieving the absorption of the impact force by the first limit member 40, and the rotation range of the rotating bracket 20 relative to the fixed bracket 10 is increased, that is, the rotating bracket 20 and the propeller 200 can be lifted at a larger angle, thereby releasing the impact force, preventing the impact force from damaging the internal structure of the lifting device 100 and the propeller 200, and ensuring the normal operation of the lifting device 100 and the propeller 200.

[0047] When the first limit member 40 releases the restriction on at least one of the first connecting mechanism 60 and the second connecting mechanism 70, the rotation range of the rotating bracket 20 relative to the fixed bracket 10 is increased, thereby enabling the release of the impact force. However, when the impact force on the lifting device 100 disappears, if the first connecting mechanism 60 is still able to rotate relative to the fixed bracket 10, and / or the second connecting mechanism 70 is still able to rotate relative to the rotating bracket 20, the driving force of the power mechanism 30 cannot be stably transmitted to the driving bracket 20, thereby causing the power mechanism 30 to be unable to drive the rotating bracket 20 to rotate and lift relative to the fixed bracket 10, affecting the normal operation of the lifting device 100. Therefore, in some embodiments, after the first limit member 40 releases the restriction on at least one of the first connecting mechanism 60 and the second connecting mechanism 70 to allow the rotating bracket 20 to increase its rotation range relative to the fixed bracket 10, the operator can also replace the new first limit member 40, and the new first limit member 40 re-restricts the first connecting mechanism 60 to remain fixed relative to the fixed bracket 10, and / or restricts the second connecting mechanism 70 to remain fixed relative to the rotating bracket 20, so that the power mechanism 30 can drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10. For example, after the first limiter 40 releases the restriction on the first connection mechanism 60 to allow the rotation range of the rotating bracket 20 to increase relative to the fixed bracket 10, the operator can replace a new first limiter 40, and the new first limiter 40 re-restricts the first connection mechanism 60 to remain relatively fixed to the fixed bracket 10; for another example, after the first limiter 40 releases the restriction on the second connection mechanism 70 to allow the rotation range of the rotating bracket 20 to increase relative to the fixed bracket 10, the operator can also replace a new first limiter 40, and the new first limiter 40 re-restricts the first connection mechanism 60 to remain relatively fixed to the fixed bracket 10. The second connecting mechanism 70 remains relatively fixed to the rotating bracket 20; for example, after the first limit member 40 releases the restriction on the first connecting mechanism 60 and the second connecting mechanism 70 to allow the rotating bracket 20 to increase its rotation range relative to the fixed bracket 10, the operator can also replace the new first limit member 40, and the new first limit member 40 re-restricts the first connecting mechanism 60 to remain relatively fixed to the fixed bracket 10, and restricts the second connecting mechanism 70 to remain relatively fixed to the rotating bracket 20, so that the power mechanism 30 can drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10.

[0048] See also Figure 1 and Figure 2 In some embodiments, the power mechanism 30 may further include a driving assembly 37, and the driving assembly 37 is used to drive the telescopic rod 353 to extend and retract relative to the main body 351.

[0049] Specifically, in some embodiments, the driving assembly 37 may be a hydraulic cylinder, a pneumatic cylinder or a motor, etc. The driving assembly 37 and the telescopic assembly 35 may be connected via one or more structures such as a gear assembly, a pulley assembly, a screw assembly or a hydraulic transmission, so that the driving force of the driving assembly 37 can be transmitted to the telescopic rod 353, so that the telescopic rod 353 can be telescoped relative to the main body 351, thereby driving the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10, thereby realizing the propeller 200 ( Fig.11 The tilting device 100 and the propeller 200 are prevented from being damaged by impact force.

[0050] In the lifting device 100 of the present application, the power mechanism 30 drives the rotating bracket 20 to rotate relative to the fixed bracket 10 via the first connecting mechanism 60 and the second connecting mechanism 70 to achieve the lifting of the rotating bracket 20, and the first limiting member 40 is configured on at least one of the first connecting mechanism 60 and the second connecting mechanism 70. When the lifting device 100 is subjected to impact force, the first limiting member 40 can release the restriction on at least one of the first connecting mechanism 60 and the second connecting mechanism 70 to allow the rotating bracket 20 to rotate relative to the fixed bracket 10. The rotation range is increased, thereby achieving the release of the impact force and preventing the impact force from damaging the internal structure of the lifting device 100, thereby ensuring the normal operation of the lifting device 100.

[0051] The warping device 100 is further explained below with reference to the accompanying drawings.

[0052] See also Figure 1 and Figure 2 In the first aspect of the tilting device 100 of the present application, the fixed bracket 10 includes a first end 11 and a second end 13 opposite to each other, and the rotating bracket 20 is rotatably connected to the second end 13 of the fixed bracket. The first limiter 40 is configured on the first connecting mechanism 60, and the first limiter 40 is used to limit the rotation of the first connecting mechanism 60 relative to the fixed bracket 10, and when the tilting device 100 is subjected to an impact force, the first limiter 40 is also used to allow a rotation pair to be formed between the first connecting mechanism 60 and the fixed bracket 10.

[0053] When the tilting device 100 is subjected to an impact force, a revolving pair is formed between the first connecting mechanism 60 and the fixed bracket 10, that is, the first connecting mechanism 60 is in direct contact with the fixed bracket 10 and can rotate relative to each other. Therefore, the revolving pair formed between the first connecting mechanism 60 and the fixed bracket 10 can increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, that is, increase the tilting range of the rotating bracket 20, thereby releasing the impact force and preventing the tilting device 100 from being damaged.

[0054] Specifically, please combine Fig.11If the tilting device 100 is not provided with the first limiter 40, and the first connection structure 60 and the second connection structure 70 are in the unrestricted state, the rotation and tilting of the rotating bracket 20 relative to the fixed bracket 10 is not constrained. Therefore, when the propeller 200 is in the propulsion state, the propeller 200 causes continuous disorderly fluctuations under the disordered fluctuations of the water flow, resulting in the power generated by the propeller 200 being unable to effectively drive the hull 1001 to move, affecting the normal operation of the movable device 1000 in the water area. Therefore, in this embodiment, the first connection mechanism 60 is fixed relative to the fixed bracket 10 under the restriction of the first limiter 40, so that when the rotating bracket 20 is effectively driven to tilt by the power mechanism 30, the rotating bracket 20 can maintain normal tilting and rotating motion relative to the fixed bracket 10, thereby ensuring that the power generated by the propeller 200 can drive the hull 1001 to move. Furthermore, when the lifting device 100 is subjected to an impact force, the first stopper 40 releases the restriction on the first connection mechanism 60, so that a rotation pair is formed between the first connection mechanism 60 and the fixed bracket 10, thereby increasing the rotation range of the rotating bracket 20 relative to the fixed bracket 10, thereby releasing the impact force and preventing damage to the lifting device 100 and the propeller 200. It should be noted that, in some embodiments, the restriction method of the first stopper 40 on the first connection mechanism 60 includes but is not limited to abutment, clamping or elastic connection.

[0055] In addition, in certain embodiments, in order to prevent the driving force generated by the power mechanism 30 from being unable to be stably transmitted to the rotating bracket 20, resulting in the rotating bracket 20 being unable to rotate and lift relative to the fixed bracket 10, after the impact force on the lifting device 100 disappears, the operator can replace the new first limit member 40, and the new first limit member 40 re-limits the first connecting mechanism 60 to remain fixed to the fixed bracket 10, so as to ensure that the power mechanism 30 can drive the rotating bracket 20 to rotate and lift relative to the fixed bracket 10.

[0056] See also Figures 1 to 3 Furthermore, in some embodiments, the lifting device 100 may also include a second limiting member 50 disposed on the fixed bracket 10, and the second limiting member 50 and the first limiting member 40 jointly clamp the first connecting mechanism 60 to limit the first connecting mechanism 60 to remain fixed relative to the fixed bracket 10.

[0057] Please combine Fig.11In some embodiments, the fixed bracket 10 can be installed on the hull 1001 by means of threaded connection or welding. In other embodiments, the fixed bracket 10 can be installed on the hull 1001 by means of a fixing device (not shown). When the fixed bracket 10 is installed on the hull 1001, the lifting of the propeller 200 is the movement of the propeller 215 of the propeller 200 in a direction away from the hull 1001. When the lifting device 100 is subjected to an impact force and the first limiter 40 releases the restriction on the first connecting mechanism 60, the first connecting mechanism 60 can rotate relative to the fixed bracket 10, so that the power mechanism 30 rotates relative to the fixed bracket 10 together with the first connecting mechanism 60, thereby realizing an increase in the rotation range of the rotating bracket 20 relative to the fixed bracket 10, that is, realizing the lifting of the rotating bracket 20, and the power mechanism 30 will not cause deformation, thereby preventing the power mechanism 30 from being damaged by the impact of the rigid force. After the impact force disappears, the first connection mechanism 60 can fall back in the opposite direction to the position before the rotation relative to the fixed bracket 10. At this time, due to the effect of inertia, the angle of the first connection mechanism 60 rotating in the opposite direction may be too large. If the second limiter 50 is not provided, the first connection mechanism 60 will collide with the hull 1001, causing the power mechanism 30 or other structures of the lifting device 100 to be deformed and damaged, affecting the normal lifting. Therefore, the provision of the second limiter 50 can prevent the lifting device 100 from colliding with the hull 1001 and causing damage, thereby ensuring the normal operation of the lifting device 100. In addition, the first limiter 40 and the second limiter 50 jointly limit the first connection mechanism 60 to be fixed relative to the fixed bracket 10, thereby ensuring that the lifting device 100 can drive the propeller 200 to lift, and the normal operation of the movable device 1000 in the water area.

[0058] In some embodiments, the second stopper 50 and the first stopper 40 are respectively located on opposite sides of the first connection mechanism 60. Specifically, in some embodiments, the fixing bracket 10 includes a first side 12 and a second side 14 that are opposite to each other, the first stopper 40 is closer to the first side 12 of the fixing bracket than the second stopper 50, and the second stopper 50 is a protrusion disposed on the fixing bracket 10.

[0059] In some embodiments, the second side 14 of the fixing bracket may be the side of the fixing bracket 10 facing the hull 1001. The second stopper 50 may be disposed on the second side 14 of the fixing bracket, or the second stopper 50 may be disposed at any position between the first side 12 of the fixing bracket and the second side 14 of the fixing bracket, and the first stopper 40 is closer to the first side 12 of the fixing bracket than the second stopper 50, and the first connection mechanism 60 is located between the first stopper 40 and the second stopper 50.

[0060] In some embodiments, the second stopper 50 is a protrusion disposed on the fixing bracket 10, and in the direction from the second side 14 of the fixing bracket to the first side 12 of the fixing bracket, the projection of the second stopper 50 on the first connecting mechanism 60 is completely located on the first connecting mechanism 60, and the projection area of ​​the second stopper 50 on the first connecting mechanism 60 is smaller than the area of ​​one side of the first connecting mechanism 60 in the direction from the second side 14 of the fixing bracket to the first side 12 of the fixing bracket. Thus, the second stopper 50 can contact part of the first connecting mechanism 60, so that the second stopper 50 and the first stopper 40 can limit the first connecting mechanism 60 to remain fixed relative to the fixing bracket 10, and the size of the second stopper 50 is small, so as to avoid the second stopper 50 from interfering with other structural parts.

[0061] In other embodiments, the second stopper 50 is a protrusion disposed on the fixed bracket 10, and in the direction in which the second side 14 of the fixed bracket points to the first side 12 of the fixed bracket, the projection of the second stopper 50 on the first connection mechanism 60 is completely located on the first connection mechanism 60, and the projection area of ​​the second stopper 50 on the first connection mechanism 60 is equal to the area of ​​one side of the first connection mechanism 60 in the direction in which the second side 14 of the fixed bracket points to the first side 12 of the fixed bracket. Thus, the second stopper 50 can be in full contact with the first connection mechanism 60, preventing the first connection mechanism 60 from breaking through the restriction of the second stopper 50 when the first connection mechanism 60 rotates relative to the fixed bracket 10, thereby ensuring the restriction effect of the second stopper and the first stopper on the first connection mechanism 60.

[0062] In some further embodiments, the second limit member 50 is a protrusion provided on the fixed bracket 10, and in the direction from the first side 12 of the fixed bracket to the second side 14 of the fixed bracket, the projection of the first connecting mechanism 60 on the second limit member 50 is completely located on the second limit member 50, and the projection area of ​​the first connecting mechanism 60 on the second limit member 50 is smaller than the area of ​​one side of the second limit member 50 in the direction from the first side 12 of the fixed bracket to the second side 14 of the fixed bracket.

[0063] See also Figure 2 and Figure 3 In some embodiments, the first connection mechanism 60 may further include a swing arm 63 and a seat body 65. The swing arm 63 includes a first end 631 and a second end 633 opposite to each other, and the first end 631 of the swing arm is rotatably connected to the fixed bracket 10. The first limiter 40 is disposed on the swing arm 63 and / or the seat body 65. When the first limiter 40 releases the restriction on the first connection mechanism 60, a rotation pair is formed between the swing arm 63 and the fixed bracket 10.

[0064] Among them, the first shaft 61 can be fixedly installed on the seat body 65, and the first end 31 of the power mechanism is rotatably connected to the seat body 65 through the first shaft 61. In the case where the lifting device 100 is subjected to impact force, the first limiter 40 allows a revolving pair to be formed between the first connecting mechanism 60 and the fixed bracket 10. At this time, the two components forming the revolving pair between the first connecting mechanism 60 and the fixed bracket 10 can be: the swing arm 63 and the fixed bracket 10. The revolving pair elements can be: the connecting surface between the swing arm 63 and the fixed bracket 10 and the connecting surface on the side wall 17 of the fixed bracket 10 connected to the swing arm 63.

[0065] Specifically, in some embodiments, when the tilting device 100 is not subjected to an impact force, the first stopper 40 limits the swing arm 63 from rotating relative to the fixed bracket 10, that is, the swing arm 63 and the seat body 65 are both fixed relative to the fixed bracket 10. If the propeller 200 needs to be tilted, the power mechanism 30 can drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10, so that the propeller 200 can adjust the tilting angle. At this time, the first end 31 of the power mechanism can rotate relative to the seat body 65, and the second end 33 of the power mechanism can rotate relative to the rotating bracket 20. When the lifting device 100 is subjected to impact force, the first limit member 40 releases the restriction on the swing arm 63, and the first limit member 40 allows the swing arm 63 to rotate relative to the fixed bracket 10, that is, the swing arm 63 and the seat body 65 both rotate relative to the fixed bracket 10, so that the power mechanism 30 rotates relative to the fixed bracket 10 together with the seat body 65. Compared with the power mechanism 30 driving the rotating bracket 20 to rotate relative to the fixed bracket 10 for lifting, the rotation of the swing arm 63 relative to the fixed bracket 10 can increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, thereby releasing the impact force on the lifting device 100 and preventing the structure of the lifting device 100 from being damaged.

[0066] See also Figure 2 In some embodiments, the seat body 65 is provided with an installation space 651 , and the first end 31 of the power mechanism is rotatably installed in the installation space 651 through the first shaft 61 .

[0067] Specifically, in some embodiments, the seat 65 may be provided with a groove, and the installation space 651 is a groove. Among them, the groove may be recessed from the seat 65 toward the side away from the power mechanism 30, and the first shaft 61 is fixedly installed in the groove. The setting of the groove can prevent the first shaft 61 from interfering with other structures, thereby improving the installation stability of the first shaft 61. In addition, the first shaft 61 is accommodated in the installation space 651, and the first end 31 of the power mechanism is connected to the first shaft 61, thereby reducing the space occupied by the power mechanism 30 and the seat 65, thereby realizing the miniaturization of the tilting device 100. In other embodiments, two spaced protrusions (not shown) may be provided on the seat 65, and the installation space 651 is the gap between the two protrusions. Among them, the protrusion may extend from the seat 65 toward the direction of the power mechanism 30, and the first shaft 61 may be fixedly arranged between the two protrusions. The setting of the protrusion can prevent the first shaft 61 from interfering with other structures, thereby improving the installation stability of the first shaft 61.

[0068] See also Figure 2 and Figure 3 In some embodiments, when the first stopper 40 restricts the first connection mechanism 60 to remain relatively fixed to the fixing bracket 10, the first connection mechanism 60 contacts the first stopper 40. When the first stopper 40 releases the restriction on the first connection mechanism 60, the portion of the first stopper 40 disposed on the rotation path of the first connection mechanism 60 and the portion fixedly connected to the fixing bracket 10 break and fail.

[0069] Specifically, when the first connection mechanism 60 contacts the first limiter 40, the first limiter 40 and the second limiter 50 can jointly clamp the seat body 65 and / or the swing arm 63 to limit the first connection mechanism 60 to remain relatively fixed with the fixed bracket 10. When the tilting device 100 is subjected to an impact force, the first limiter 40 on the rotation path of the first connection mechanism 60 and the fixed connection and the fixed bracket 10 are broken, so that the first connection mechanism 60 can rotate relative to the fixed bracket 10. At this time, the failure of the first limiter 40 to break can absorb the impact force to avoid the impact force from damaging the internal structure of the tilting device 100. At the same time, the rotation of the first connection mechanism 60 relative to the fixed bracket 10 can also allow the rotating bracket 20 to rotate relative to the fixed bracket 10 together with the power mechanism 30, so that the power mechanism 30 is prevented from being affected by the impact force, and the rotating bracket 20 can be tilted to a higher angle, thereby releasing the impact force. It can be understood that the first limiter 40 can be made of a brittle metal material. The rigidity strength of the first stopper 40 is based on the ability to withstand the main body of the propeller 200 being lifted up by the power mechanism 30 driving the rotating bracket 20. As the weakest rigid component on the entire propeller 200, when an impact force occurs on the entire power transmission path of the propeller 200, the first stopper 40, as the weakest rigid component, will first produce a rigid fracture, so that the first stopper 40 will fail first, and the first connection structure 60 will be released from the limit, thereby allowing the first connection structure 60 to rotate relative to the fixed bracket 10, thereby releasing the impact force and protecting other power transmission components on the propeller 200.

[0070] See also Figure 2 In some embodiments, the first limit member 40 may include a first portion 41 mounted on the fixed bracket 10, the first portion 41 is located on the rotation path of the first connecting mechanism 60, and is used to contact the first connecting mechanism 60 when the first connecting mechanism 60 rotates.

[0071] Specifically, in some embodiments, the first portion 41 may be fixedly mounted on the fixed bracket 10 and at least partially located on the rotation path of the first connecting mechanism 60. When the first connecting mechanism 60 rotates, the first connecting mechanism 60 contacts the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60, so that the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60 and the portion fixedly connected to the fixed bracket 10 are broken, thereby absorbing the impact force and preventing the warping device 100 from being damaged. The connection method between the first portion 41 and the fixed bracket 10 includes but is not limited to bonding or welding, etc. In some embodiments, the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60 may correspond to the swing arm 63. When the first connecting mechanism 60 rotates, the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60 may contact the swing arm 63. In other embodiments, the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60 may correspond to the seat body 65. When the first connecting mechanism 60 rotates, the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60 may contact the seat body 65.

[0072] In other embodiments, the first stopper 40 includes a first portion 41 fixed to the fixing bracket 10 and a second portion 42 fixed to the first portion 41. The second portion 42 is located on the rotation path of the first connecting mechanism 60 and is used to contact the first connecting mechanism 60 when the first connecting mechanism 60 rotates.

[0073] Specifically, in some embodiments, the second portion 42 may be sleeved on the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60, and may be completely located on the rotation path of the first connecting mechanism 60. When the first connecting mechanism 60 rotates, the first connecting mechanism 60 may contact the second portion 42, so that the position of the first portion 41 not connected to the second portion 42 is broken, thereby absorbing the impact force and preventing the tilting device 100 from being damaged. In other embodiments, the second portion 42 may be sleeved on the portion of the first portion 41 located on the rotation path of the first connecting mechanism 60, and may be partially located on the rotation path of the first connecting mechanism 60. When the first connecting mechanism 60 rotates, the first connecting mechanism 60 may contact the portion of the second portion 42 located on the rotation path of the first connecting mechanism 60, so that the portion of the second portion 42 located on the rotation path of the first connecting mechanism 60 and the portion of the second portion 42 not located on the rotation path of the first connecting mechanism 60 are broken, thereby absorbing the impact force and preventing the tilting device 100 from being damaged. In some embodiments, the portion of the second portion 42 located on the rotation path of the first connection mechanism 60 may correspond to the swing arm 63, and when the first connection mechanism 60 rotates, the portion of the second portion 42 located on the rotation path of the first connection mechanism 60 may contact the swing arm 63. In other embodiments, the portion of the second portion 42 located on the rotation path of the first connection mechanism 60 may correspond to the seat body 65, and when the first connection mechanism 60 rotates, the portion of the second portion 42 located on the rotation path of the first connection mechanism 60 may contact the seat body 65.

[0074] In some embodiments, the contact area between the second portion 42 and the first connection mechanism 60 is greater than the contact area between the first portion 41 and the first connection mechanism 60 when the second portion 42 is not provided. The provision of the second portion 42 can increase the contact area between the first stopper 40 and the first connection mechanism 60, thereby, on the one hand, when subjected to an impact force, the impact force can act more on the first stopper 40, thereby facilitating the breaking of the first stopper 40; on the other hand, when not subjected to an impact force, the pressure of the first stopper 40 on the first connection mechanism 60 when the first connection mechanism 60 contacts the first stopper 40 can be reduced, thereby preventing the first connection mechanism 60 from being damaged due to collision, thereby ensuring the stability of the tilting device 100.

[0075] It can be understood that, as an alternative to the above-mentioned embodiment, the first part 41 can be fixed to the fixed bracket 10, and the second part 42 can be located on the rotation path of the first connecting mechanism 60, and the first part 41 can be fixed to the first connecting mechanism 60, and the second part 42 can be located on the rotation path of the fixed bracket 10 relative to the first connecting mechanism 60. Specifically, a receiving groove is provided on the side wall 17 of the fixed bracket 10 and the first connecting mechanism 60 for rotational cooperation, the first part 41 is fixed to the first connecting mechanism 60 adjacent to the receiving groove, the second part 42 is received in the receiving groove, and the second part 42 is abutted against the inner wall of the receiving groove, so that when the first part 41 and the second part 42 are not broken, the first limiter 40 can limit the first connecting mechanism 60 from being fixed relative to the fixed bracket 10. When the propeller 200 is subjected to impact force, the first part 41 and the second part 42 are broken, the first part 41 is fixed to the first connecting mechanism 60 and will not be lost, and the second part 42 is still received in the receiving groove and will not be lost due to the clamping cooperation with the receiving groove, thereby preventing the second part 42 from falling into the water and causing damage to the propeller 215 ( Fig.11 damage shown).

[0076] See also Figure 2 and Figure 4 Furthermore, in some embodiments, the fixing bracket 10 may be provided with a third limiter 19, and when the first limiter 40 releases the restriction on the first connecting mechanism 60, the third limiter 19 is used to limit the movement range of the first connecting mechanism 60.

[0077] When the first stopper 40 releases the restriction on the first connection mechanism 60, the first connection mechanism 60 can rotate relative to the fixed bracket 10, so that the power mechanism 30 rotates relative to the fixed bracket 10 along with the first connection mechanism 60, thereby releasing the impact force. Fig.11 As shown in FIG. 1 , if the rotation angle of the rotating bracket 20 relative to the fixed bracket 10 is too large, the propeller 200 will collide with the hull 1001, thereby causing the propeller 200 ( Fig.11 Thus, the third stopper 19 can limit the range of motion of the first connection mechanism 60, that is, limit the range of rotation of the rotating bracket 20 relative to the fixed bracket 10, and prevent the rotating bracket 20 from rotating too much relative to the fixed bracket 10, thereby preventing the propeller 200 from being damaged.

[0078] In some embodiments, the third limiting member 19 is disposed on the fixing bracket 10 near the first connecting mechanism 60 where the fixing bracket 10 is rotatably connected.

[0079] Specifically, in some embodiments, the third limit member 19 can be a protrusion protruding from the side wall 17 of the fixed bracket toward the power mechanism 30, and the third limit member 19 is arranged on the fixed bracket 10 near the position where the swing arm 63 is rotatably connected to the fixed bracket 10, so that the third limit member 19 can cooperate with the swing arm 63 to limit the movement range of the swing arm 63.

[0080] More specifically, in some embodiments, the third limiting member 19 has a first limiting surface 191 and a second limiting surface 193 , and when the first limiting member 40 releases the restriction on the first connecting mechanism 60 , the first connecting mechanism 60 rotates between the first limiting surface 191 and the second limiting surface 193 .

[0081] Further, in some embodiments, the swing arm 63 includes a first side 635 and a second side 637 opposite to each other, and the first side 635 of the swing arm is closer to the first stopper 40 than the second side 637 of the swing arm. When the first connecting mechanism 60 rotates relative to the fixed bracket 10 along the first rotation direction R1, the first stopper surface 191 can contact the first side 635 of the swing arm, thereby limiting the rotation range of the swing arm 63 along the first rotation direction R1, and preventing the propeller 200 from colliding with the hull 1001 and causing damage to the propeller 200. The first rotation direction R1 is the direction in which the rotating bracket 20 tilts. When the first connecting mechanism 60 rotates relative to the fixed bracket 10 along the second rotation direction R2, the second stopper surface 193 can contact the second side 637 of the swing arm, thereby limiting the rotation range of the swing arm 63 along the second rotation direction R2, and preventing the tilting device 100 from colliding with the hull 1001 and causing damage to the tilting device 100. It should be noted that the second rotation direction R2 is opposite to the first rotation direction R1.

[0082] In other embodiments, when the first stopper 40 restricts the first connection mechanism 60 to remain relatively fixed to the fixing bracket 10, the first connection mechanism 60 contacts the first stopper 40. When the first stopper 40 releases the restriction on the first connection mechanism 60, the first stopper 40 deforms and fails. Figure 1 and Figure 2 The structure of the tilting device 100 shown in the figure is the same except for the first limiter 40; Figure 1 and Figure 2 The first stopper 40 in the tilting device 100 shown is different.

[0083] Specifically, when the tilting device 100 is subjected to an impact force, the first stopper 40 may be deformed and fail, thereby causing the first connection mechanism 60 to rotate relative to the fixed bracket 10. At this time, the deformation and failure of the first stopper 40 can absorb the impact force on the tilting device 100 to prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the rotation of the first connection mechanism 60 relative to the fixed bracket 10 can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, thereby allowing the rotating bracket 20 to be tilted to a higher angle, thereby not only releasing the impact force, but also realizing the thruster 200 ( Fig.11 to avoid obstacles.

[0084] In some embodiments, the first limiting member 40 may include an elastic member (not shown), one end of the first limiting member 40 is fixedly connected to the first connecting mechanism 60, and the other end is fixedly connected to the fixed bracket 10, and the first limiting member 40 provides elastic force to the first connecting mechanism 60 to connect the first connecting mechanism 60 to the fixed bracket 10.

[0085] Specifically, when the tilting device 100 is not subjected to an impact force, or the impact force on the tilting device 100 is small, the elastic force of the elastic member can connect the first connecting mechanism 60 and the fixed bracket 10, and limit the first connecting mechanism 60 to remain relatively fixed with the fixed bracket 10. When the tilting device 100 is subjected to an impact force, the impact force can overcome the elastic force generated by the elastic member to allow the first connecting mechanism 60 to rotate relative to the fixed bracket 10. When the magnitude of the impact force is greater than the tensile strength of the elastic member, the elastic member deforms and fails. Thus, the deformation and failure of the first limit member 40 can prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the rotation of the first connecting mechanism 60 relative to the fixed bracket 10 can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, so that the rotating bracket 20 can be tilted to a higher angle to release the impact force. In some embodiments, the elastic member can be one of a spring, a torsion spring and a tension spring, which is not limited here.

[0086] See also Figure 5 In the second aspect of the tilting device 100 of the present application, the first limiter 40 is arranged on the first connection mechanism 60, and the first limiter 40 is used to limit the movement of the first connection mechanism 60 relative to the fixed bracket 10, and when the tilting device 100 is subjected to an impact force, the first limiter 40 is also used to allow a moving pair to be formed between the first connection mechanism 60 and the fixed bracket 10. At this time, the two components forming the moving pair between the first connection mechanism 60 and the fixed bracket 10 can be: the first shaft 61 and the fixed bracket 10. The moving pair element can be: the outer surface of the first shaft 61 and the surface on the side wall 17 of the fixed bracket that contacts the outer surface of the first shaft 61.

[0087] When the tilting device 100 is subjected to an impact force, a moving pair is formed between the first connecting mechanism 60 and the fixed bracket 10, that is, the first connecting mechanism 60 is in direct contact with the fixed bracket 10 and can move relative to each other. Therefore, the moving pair formed between the first connecting mechanism 60 and the fixed bracket 10 can increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, that is, increase the tilting range of the rotating bracket 20, thereby releasing the impact force and preventing the tilting device 100 from being damaged.

[0088] Specifically, please combine Fig.11 If the first limiter is not provided in the tilting device, and the first connection mechanism and the second connection mechanism are in the unrestricted state, the rotation and tilting of the rotating bracket relative to the fixed bracket is not constrained. Therefore, when the propeller is in the propulsion state, the propeller causes continuous disordered fluctuations under the disordered fluctuations of the water flow, resulting in the power generated by the propeller being unable to effectively drive the hull to move, affecting the normal operation of the movable device in the water area. Therefore, in this embodiment, the first connection mechanism 60 is fixed relative to the fixed bracket 10 under the restriction of the first limiter 40, so that when the rotating bracket 20 is effectively driven to tilt by the power mechanism 30, the rotating bracket 20 maintains normal rotation and tilting relative to the fixed bracket 10, thereby ensuring that the power generated by the propeller 200 can drive the hull 1001 to move. In addition, when the tilting device 100 is subjected to impact force, the first limiter 40 releases the restriction on the first connection mechanism 60, so that a moving pair is formed between the first connection mechanism 60 and the fixed bracket 10, thereby releasing the impact force and preventing damage to the tilting device 100 and the propeller 200.

[0089] In addition, in certain embodiments, in order to prevent the driving force generated by the power mechanism 30 from being unable to be stably transmitted to the rotating bracket 20, resulting in the rotating bracket 20 being unable to rotate and lift relative to the fixed bracket 10, after the impact force on the lifting device 100 disappears, the operator can replace the new first limit member 40, and the new first limit member 40 re-limits the first connecting mechanism 60 to remain fixed to the fixed bracket 10, so as to ensure that the power mechanism 30 can drive the rotating bracket 20 to rotate and lift relative to the fixed bracket 10.

[0090] See also Figure 5 and Figure 6 In some embodiments, the fixed bracket 10 may include a base 15 and a side wall 17 connected to the base 15, the first connecting mechanism 60 is fixedly connected to the base 15 through the first limiting member 40, and the first connecting mechanism 60 is connected to the side wall 17 of the fixed bracket. When the first limiting member 40 releases the restriction on the first connecting mechanism 60, the first connecting mechanism 60 moves along the side wall 17 of the fixed bracket.

[0091] Specifically, please combine Figure 5 and Figure 6In some embodiments, when the lifting device 100 is not subjected to impact force, the first stopper 40 limits the first connection mechanism 60 from moving along the side wall 17 of the fixed bracket, that is, the first connection mechanism 60 is fixed relative to the base 15. If the propeller 200 encounters an obstacle or the propeller 200 needs to be lifted, the power mechanism 30 can drive the rotating bracket 20 to rotate and lift relative to the fixed bracket 10, so that the propeller 200 can be lifted to avoid obstacles or lift out of the water. At this time, the first end 31 of the power mechanism can rotate relative to the base 15, and the second end 33 of the power mechanism can rotate relative to the rotating bracket 20. When the lifting device 100 is subjected to impact force, the first limit member 40 releases the restriction on the first connecting mechanism 60, and the first limit member 40 allows the first connecting mechanism 60 to move along the side wall 17 of the fixed bracket, so that the power mechanism 30 moves relative to the side wall 17 of the fixed bracket together with the first connecting mechanism 60. Compared with the power mechanism 30 driving the rotating bracket 20 to rotate relative to the fixed bracket 10 to lift, the movement of the first connecting mechanism 60 along the side wall 17 of the fixed bracket can increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, thereby allowing the rotating bracket 20 to be lifted to a higher angle to release the impact force, thereby preventing damage to the structure of the lifting device 100.

[0092] See also Figure 6 In some embodiments, the base 15 is provided with a receiving space 151 , the first shaft 61 is located in the receiving space 151 , the first limit member 40 is connected to the first shaft 61 , and the first end 31 of the power mechanism is rotatably connected to the first shaft 61 .

[0093] Specifically, in some embodiments, the receiving space 151 may be a groove. The groove may be recessed from the base 15 toward a side away from the power mechanism 30, and the first shaft 61 may be rotatably mounted in the groove. The setting of the groove can prevent the first shaft 61 from interfering with other structures, thereby improving the installation stability of the first shaft 61. In addition, the first shaft 61 is accommodated in the receiving space 151, and the first end 31 of the power mechanism is connected to the first shaft 61, thereby reducing the space occupied by the power mechanism 30 and the base 15, thereby realizing the miniaturization of the tilting device 100. In other embodiments, two spaced protrusions (not shown) may be provided on the base 15, and the receiving space 151 is the gap between the two protrusions. The protrusion may extend from the base 15 toward the direction of the power mechanism 30, and the first shaft 61 may be rotatably arranged between the two protrusions. The setting of the protrusion can prevent the first shaft 61 from interfering with other structures, thereby improving the installation stability of the first shaft 61.

[0094] See also Figure 5 and Figure 6In some embodiments, when the first stopper 40 limits the movement of the first shaft 61 relative to the side wall 17 of the fixed bracket, the first stopper 40 is connected to the first shaft 61. When the first stopper 40 allows the first shaft 61 to move relative to the side wall 17 of the fixed bracket, the first stopper 40 breaks and fails.

[0095] It should be noted that, in some embodiments, the first stopper 40 may include a screw or a pin made of a brittle material. Specifically, the first stopper 40 is provided through the base 15 and connected to the first shaft 61 to limit the movement of the first shaft 61 relative to the side wall 17 of the fixed bracket. When the lifting device 100 is subjected to an impact force, the first stopper 40 breaks, so that the first shaft 61 can move relative to the side wall 17 of the fixed bracket. At this time, the failure of the first stopper 40 to break can absorb the impact force to avoid the impact force from damaging the internal structure of the lifting device 100. At the same time, the movement of the first shaft 61 relative to the side wall 17 of the fixed bracket can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, so that the rotating bracket 20 can be tilted to a higher angle, thereby achieving the release of the impact force. It is understandable that the first stopper 40 can select a screw or a pin made of a brittle metal material. The rigidity of the first stopper 40 is based on the ability to withstand the main engine of the propeller 200 driven by the power mechanism 30 to drive the rotating bracket 20 to tilt. The first limit member 40 is the component with the weakest rigidity on the entire propeller 200. When an impact force occurs on the entire power transmission path of the propeller 200, the first limit member 40, as the component with the weakest rigidity, will first produce rigid fracture, so that the first limit member 40 will fail first, thereby releasing the limit on the first connecting structure 60, and then allowing the first connecting structure 60 to rotate relative to the fixed bracket 10, thereby releasing the impact force and protecting other power transmission components on the propeller 200.

[0096] In some embodiments, the outer peripheral wall of the first position-limiting member 40 is provided with a groove 43. Specifically, the groove 43 is recessed from the outer peripheral wall of the first position-limiting member 40 toward the direction of the central axis of the first position-limiting member 40. Therefore, when the first position-limiting member 40 is subjected to an impact force, the impact force can be more concentrated on the groove 43. Compared with the case where the outer peripheral wall of the first position-limiting member 40 is not provided with the groove 43, the first position-limiting member 40 can be more easily broken from the groove 43, thereby ensuring that the first position-limiting member 40 absorbs the impact force. In some embodiments, when the first position-limiting member 40 passes through the base 15 and is connected to the first shaft 61, the groove 43 does not extend into the interior of the first shaft 61, but is located outside the first shaft 61, thereby ensuring that the impact force received by the warping device 100 can be concentrated in the groove 43, thereby ensuring that the first position-limiting member 40 can be broken and failed, so as to achieve the movement of the first shaft 61 relative to the side wall 17 of the fixed bracket.

[0097] Further, in some embodiments, the first stopper 40 includes a first end 45 and a second end 47 opposite to each other along the length direction. The groove 43 is located at least one of the first end 45 of the first stopper, the second end 47 of the first stopper, and between the first end 45 of the first stopper and the second end 47 of the first stopper. Specifically, the provision of the plurality of grooves 43 can ensure that the first stopper 40 fails to break, thereby preventing the tilting device 100 from being damaged due to the failure of the first stopper 40 to break when the tilting device 100 is subjected to an impact force.

[0098] In some embodiments, the extension direction of the first stopper 40 is consistent with or perpendicular to the extension direction of the first shaft 61. The extension direction of the first stopper 40 is the direction from the first end 45 of the first stopper to the second end 47 of the first stopper. When the first stopper 40 penetrates the side wall 17 and the base 15 of the fixed bracket and extends into the receiving space 151 to connect with the first shaft 61, the extension direction of the first stopper 40 is consistent with the extension direction of the first shaft 61. In some embodiments, the base 15 includes a first side 153 and a second side 155 opposite to each other, the first side 153 of the base faces the power mechanism 30, and the first stopper 40 can penetrate the second side 155 of the base and extend into the receiving space 151 to connect with the first shaft 61. At this time, the extension direction of the first stopper 40 is perpendicular to the extension direction of the first shaft 61.

[0099] Since the first stopper 40 can break to absorb the impact force when the lifting device 100 is subjected to an impact force, thereby preventing the internal structure of the lifting device 100 from being damaged by the impact force, and after the impact force disappears, in order to ensure that the power mechanism 30 can still drive the rotating bracket 20 to rotate and lift relative to the fixed bracket 10 through the first connecting mechanism 60 and the second connecting mechanism 70, it is necessary to replace a new first stopper 40 so that the new first stopper 40 can re-limit the first connecting mechanism 60 to remain relatively fixed with the fixed bracket 10. Therefore, compared with the first stopper 40 penetrating the side wall 17 and the base 15 of the fixed bracket and extending into the receiving space 151 to connect with the first shaft 61, the first stopper 40 penetrating the second side 155 of the base and extending into the receiving space 151 can facilitate the first stopper 40 to fall off after breaking, so that it is more convenient for the operator to replace the first stopper 40, simplifying the operation steps.

[0100] See also Figure 5 and Figure 6 In some embodiments, a guide member 90 is provided on the side wall 17 of the fixed bracket, and the guide member 90 is used to guide the first shaft 61 to move along the first moving direction Z1 relative to the fixed bracket 10, and to fall back along the second moving direction Z2.

[0101] When the lifting device 100 is subjected to an impact force, the first shaft 61 can move relative to the fixed bracket 10 along the first moving direction Z1, the first moving direction Z1 being the direction from the second side 155 of the base to the first side 153 of the base. When the first shaft 61 moves relative to the fixed bracket 10 along the first moving direction Z1, the rotating bracket 20 is lifted; when the impact force on the lifting device 100 disappears, the first shaft 61 can fall back relative to the fixed bracket 10 along the second moving direction Z2, the second moving direction Z2 being the direction from the first side 153 of the base to the second side 155 of the base. The setting of the guide member 90 can limit the moving stroke of the first shaft 61 relative to the fixed bracket 10 along the first moving direction Z1, thereby preventing the rotating bracket 20 from rotating too much relative to the fixed bracket 10, resulting in the propeller 200 and the hull 1001 ( Fig.11 on the other hand, it can prevent the first shaft 61 from separating from the power mechanism 30, thereby ensuring the normal operation of the warping device 100.

[0102] In some embodiments, the guide member 90 is a groove 91 provided on the side wall 17 of the fixed bracket, and one end of the first shaft 61 extends into the groove 91. Specifically, one end of the first shaft 61 can move relative to the fixed bracket 10 in the first moving direction Z1 in the groove 91, or fall back relative to the fixed bracket 10 in the second moving direction Z2. The guide member 90 is a groove 91 provided on the side wall 17 of the fixed bracket, which enables the tilting device 100 to guide the first shaft 61 without providing too many structural parts, thereby simplifying the installation steps of the tilting device 100.

[0103] In other embodiments, the guide member 90 is mounted on the side wall 17 of the fixed bracket, and the guide member 90 is provided with a groove 91, and one end of the first shaft 61 extends into the groove 91. Specifically, one end of the first shaft 61 can move relative to the fixed bracket 10 in the first moving direction Z1 in the groove 91, or fall back relative to the fixed bracket 10 in the second moving direction Z2. In some embodiments, the guide member 90 and the side wall 17 of the fixed bracket can be connected by a non-detachable connection method such as bonding or welding, so as to prevent the guide member 90 from falling off when the first shaft 61 moves relative to the fixed bracket 10, thereby ensuring the working stability of the tilting device 100. In other embodiments, the guide member 90 and the side wall 17 of the fixed bracket can be connected by a detachable connection method such as a threaded connection or a snap connection, so that when the guide member 90 is damaged (such as collision wear or corrosion, etc.), it can be easily disassembled for replacement.

[0104] Please continue reading Figure 5 and Figure 6In some embodiments, the first shaft 61 may include a body 611, a protrusion 613 disposed at one end of the body 611, and a wear-resistant member 615. The protrusion 613 extends into the guide member 90. The wear-resistant member 615 is sleeved on the protrusion 613 and is located between the guide member 90 and the body 611.

[0105] Specifically, in some embodiments, the main body 611 can be rotatably connected to the first end 31 of the power mechanism, and the protrusion 613 extends into the groove 91. When the first shaft 61 moves relative to the side wall 17 of the fixed bracket, the protrusion 613 can move in the groove 91. Among them, the provision of the wear-resistant part 615 can reduce the wear between the main body 611 and the guide member 90, thereby extending the service life of the first shaft 61 and reducing the cost of use. It should be noted that, in some embodiments, a roller (not shown) can be provided on the first shaft 61, and the roller is sleeved on the protrusion 613 and can move in the groove 91. The provision of the roller can ensure the stability of the movement of the first shaft 61 relative to the side wall 17 of the fixed bracket, and reduce or even avoid the problem of the protrusion 613 getting stuck in the groove 91.

[0106] In other embodiments, when the first stopper 40 limits the movement of the first shaft 61 relative to the side wall 17 of the fixed bracket, the first stopper 40 is connected to the first shaft 61, and when the first stopper 40 allows the first shaft 61 to move relative to the side wall 17 of the fixed bracket, the first stopper 40 is deformed and fails. Figure 5 and Figure 6 The structure of the tilting device 100 shown in the figure is the same except for the first limiter 40; Figure 5 and Figure 6 The first stopper 40 in the tilting device 100 shown is different.

[0107] Specifically, when the tilting device 100 is subjected to an impact force, the first stopper 40 can be deformed and fail, so that the first shaft 61 can move relative to the side wall 17 of the fixed bracket. At this time, the deformation and failure of the first stopper 40 can absorb the impact force on the tilting device 100 to prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the first shaft 61 can move relative to the side wall 17 of the fixed bracket, so that the power mechanism 30 is not subjected to the impact force, and the first shaft 61 is tilted together with the rotating bracket 20, thereby not only releasing the impact force and protecting the power mechanism 30, but also realizing the tilting of the rotating bracket 20 to drive the propeller 200 to tilt and avoid obstacles.

[0108] It is understandable that in the above Figure 5 and Figure 6Based on the implementation method, a replacement implementation method is provided, in which the first limit member 40 fixed on the base 15 is replaced by the first limit member 40 fixed on the first shaft 61, and the first limit member cooperates with the base 15 to limit the first shaft 61, so as to also limit the first shaft 61 to be fixed relative to the base 15, and when the thruster 200 is subjected to impact force, the first limit member 40 breaks, thereby releasing the position restriction of the first shaft 61, so that the first shaft 61 can move relative to the base 15, thereby absorbing the impact energy.

[0109] In some embodiments, the first stopper 40 includes an elastic member (not shown). Specifically, one end of the first stopper 40 is fixedly connected to the first shaft 61, and the other end thereof is fixedly connected to the fixed bracket 10. The first stopper 40 provides an elastic force to the first shaft 61 so that the first shaft 61 is connected to the fixed bracket 10.

[0110] Among them, when the tilting device 100 is not subjected to an impact force, or the impact force on the tilting device 100 is small, the elastic force of the elastic member can connect the first shaft 61 and the fixed bracket 10, and limit the first shaft 61 and the base 15 to be relatively fixed. When the tilting device 100 is subjected to an impact force, the impact force can overcome the elastic force generated by the elastic member to move the first shaft 61 relative to the base 15. When the magnitude of the impact force is greater than the tensile strength of the elastic member, the elastic member deforms and fails. As a result, the deformation and failure of the first limiter 40 can prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the movement of the first shaft 61 relative to the base 15 can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, so that the rotating bracket 20 can be tilted to a higher angle to release the impact force. In some embodiments, the elastic member can be one of a spring, a torsion spring and a tension spring, which is not limited here.

[0111] In some embodiments, the second end 33 of the power mechanism is rotatably connected to the rotating bracket 20 via the second shaft 71. The second connecting mechanism 70 may include the second shaft 71. The second end 33 of the power mechanism is rotatably connected to the rotating bracket 20 via the second shaft 71, so that when the driving assembly 37 drives the telescopic rod 353 of the telescopic assembly 35 to telescope relative to the main body 351, the telescopic rod 353 can push the rotating bracket 20 to rotate relative to the fixed bracket 10, thereby realizing the tilting of the rotating bracket 20.

[0112] See also Figure 7 In the third aspect of the tilting device 100 of the present application, the first limit member 40 is configured on the second connecting mechanism 70. The first limit member 40 is used to limit the rotation of the second connecting mechanism 70 relative to the rotating bracket 20. When the tilting device 100 is subjected to impact force, the first limit member 40 is also used to allow a rotating pair to be formed between the second connecting mechanism 70 and the rotating bracket 20.

[0113] When the tilting device 100 is subjected to an impact force, a revolving pair is formed between the rotating bracket 20 and the second connecting mechanism 70, that is, the rotating bracket 20 is in direct contact with the second connecting mechanism 70 and can rotate relative to each other. Therefore, the revolving pair formed between the rotating bracket 20 and the second connecting mechanism 70 can release the impact force and prevent the tilting device 100 from being damaged.

[0114] Specifically, please combine Fig.11 If the tilting device 100 is not provided with the first limiter 40, and the first connection structure 60 and the second connection structure 70 are in the unrestricted state, the rotation and tilting of the rotating bracket 20 relative to the fixed bracket 10 is not constrained. Therefore, when the propeller 200 is in the propulsion state, the propeller 200 causes continuous disorderly fluctuations under the disordered fluctuations of the water flow, resulting in the power generated by the propeller 200 being unable to effectively drive the hull 1001 to move, affecting the normal operation of the movable device 1000 in the water area. Therefore, in this embodiment, the second connection mechanism 70 is fixed relative to the rotating bracket 20 under the restriction of the first limiter 40, so that when the rotating bracket 20 is effectively driven to tilt by the power mechanism 30, the rotating bracket 20 can maintain normal tilting and rotating motion relative to the fixed bracket 10, thereby ensuring that the power generated by the propeller 200 can drive the hull 1001 to move. Furthermore, when the lifting device 100 is subjected to an impact force, the first stopper 40 releases the restriction on the second connection mechanism 70, and the second connection mechanism 70 can form a rotation pair with the rotating bracket 20, thereby releasing the impact force and preventing damage to the lifting device 100 and the propeller 200. It should be noted that, in some embodiments, the restriction method of the first stopper 40 on the second connection mechanism 70 includes but is not limited to abutment, clamping or elastic connection.

[0115] In addition, in certain embodiments, in order to prevent the driving force generated by the power mechanism 30 from being unable to be stably transmitted to the rotating bracket 20, resulting in the rotating bracket 20 being unable to rotate and tilt relative to the fixed bracket 10, after the impact force on the tilting device 100 disappears, the operator can replace the new first limit member 40, and the new first limit member 40 will re-limit the second connecting mechanism 70 to remain fixed to the rotating bracket 20, so as to ensure that the power mechanism 30 can drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10.

[0116] See also Figure 7 Furthermore, in some embodiments, the lifting device 100 may also include a second limiting member 50 disposed on the rotating bracket 20, and the second limiting member 50 and the first limiting member 40 jointly clamp the second connecting mechanism 70 to limit the second connecting mechanism 70 to remain fixed relative to the rotating bracket 20.

[0117] When the power mechanism 30 drives the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10, the second end 33 of the power mechanism can drive the second connection mechanism 70 to contact the second stopper 50, so that the driving force of the power mechanism 30 can be transmitted to the rotating bracket 20 to drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10. Therefore, the second stopper 50 can ensure that the power mechanism 30 drives the rotating bracket 20 to tilt.

[0118] Please combine Fig.11 In some embodiments, the fixing bracket 10 can be installed on the hull 1001 by means of threaded connection or welding. In other embodiments, the fixing bracket 10 can be installed on the hull 1001 by means of a fixing device (not shown). When the fixing bracket 10 is installed on the hull 1001, the lifting of the propeller 200 is the movement of the propeller 215 of the propeller 200 in a direction away from the hull 1001. When the lifting device 100 is subjected to an impact force and the first limiter 40 is released from the restricted state, the second connecting mechanism 70 can rotate relative to the fixing bracket 10, thereby increasing the rotation range of the rotating bracket 20 relative to the fixing bracket 10, and the power mechanism 30 will not cause deformation, thereby preventing the power mechanism 30 from being damaged by the impact of the rigid force. After the impact force disappears, the second connection mechanism 70 can return to the position before the rotation relative to the rotating bracket 20. At this time, due to the effect of inertia, the angle of the second connection mechanism 70 rotating in the opposite direction may be too large. If the second limiter 50 is not provided, the second end 33 of the power mechanism will collide with the rotating bracket 20, resulting in damage to the power mechanism 30 or the rotating bracket 20. Therefore, the provision of the second limiter 50 can prevent the structure of the tilting device 100 from being damaged and ensure the normal operation of the tilting device 100. In addition, the first limiter 40 and the second limiter 50 jointly limit the first connection mechanism 60 to be fixed relative to the fixed bracket 10, thereby ensuring that the tilting device 100 can drive the propeller 200 to tilt and the movable device 1000 in the water area can operate normally.

[0119] In some embodiments, the second stopper 50 and the first stopper 40 are respectively located on opposite sides of the second connection mechanism 70. Specifically, in some embodiments, the rotating bracket 20 includes a first side 22 and a second side 24 that are opposite to each other, and the first stopper 40 is closer to the first side 22 of the rotating bracket than the second stopper 50, and the second stopper 50 is a protrusion disposed on the rotating bracket 20.

[0120] In some embodiments, the second side 24 of the rotating bracket may be a side of the rotating bracket 20 facing away from the fixed bracket 10. The second stopper 50 may be disposed on the second side 24 of the rotating bracket, or the second stopper 50 may be disposed at any position between the first side 22 of the rotating bracket and the second side 24 of the rotating bracket, and the first stopper 40 is closer to the first side 22 of the rotating bracket than the second stopper 50, and the second connection mechanism 70 is located between the first stopper 40 and the second stopper 50.

[0121] In some embodiments, the second stopper 50 is a protrusion disposed on the rotating bracket 20, and in the direction in which the second side 24 of the rotating bracket points to the first side 22 of the rotating bracket, the projection of the second stopper 50 on the second connecting mechanism 70 is completely located on the second connecting mechanism 70, and the projection area of ​​the second stopper 50 on the second connecting mechanism 70 is smaller than the area of ​​one side of the second connecting mechanism 70 in the direction in which the second side 24 of the rotating bracket points to the first side 22 of the rotating bracket. Thus, the second stopper 50 can contact part of the second connecting mechanism 70, so that the second stopper 50 and the first stopper 40 can limit the second connecting mechanism 70 to remain fixed relative to the rotating bracket 20, and the size of the second stopper 50 is small, so as to avoid the second stopper 50 from interfering with other structural members.

[0122] In other embodiments, the second stopper 50 is a protrusion disposed on the rotating bracket 20, and in the direction in which the second side 24 of the rotating bracket points to the first side 22 of the rotating bracket, the projection of the second stopper 50 on the second connecting mechanism 70 is completely located on the second connecting mechanism 70, and the projection area of ​​the second stopper 50 on the second connecting mechanism 70 is equal to the area of ​​one side of the second connecting mechanism 70 in the direction in which the second side 24 of the rotating bracket points to the first side 22 of the rotating bracket. Thus, the second stopper 50 can be in full contact with the second connecting mechanism 70, preventing the second connecting mechanism 70 from breaking through the restriction of the second stopper 50 when the second connecting mechanism 70 rotates relative to the rotating bracket 20, thereby ensuring the restriction effect of the second limiter and the first limiter on the second connecting mechanism 70.

[0123] In some further embodiments, the second limit member 50 is a protrusion provided on the rotating bracket 20, and in the direction from the first side 22 of the rotating bracket to the second side 24 of the rotating bracket, the projection of the second connecting mechanism 70 on the second limit member 50 is completely located on the second limit member 50, and the projection area of ​​the second connecting mechanism 70 on the second limit member 50 is smaller than the area of ​​one side of the second limit member 50 in the direction from the first side 22 of the rotating bracket to the second side 24 of the rotating bracket.

[0124] See also Figure 7 and Figure 8In some embodiments, the second connection mechanism 70 may further include a swing arm 73 and a seat body 75. The swing arm 73 includes a first end 731 and a second end 733 opposite to each other, and the first end 731 of the swing arm is rotatably connected to the rotating bracket 20. The first limiter 40 is disposed on the swing arm 73 and / or the seat body 75. When the first limiter 40 releases the restriction on the second connection mechanism 70, a rotating pair is formed between the swing arm 73 and the rotating bracket 20.

[0125] Among them, the second shaft 71 can be fixedly installed on the seat body 75, and the second end 33 of the power mechanism is rotatably connected to the seat body 75 through the second shaft 71. In the case where the lifting device 100 is subjected to impact force, the first limiter 40 allows a rotation pair to be formed between the second connection mechanism 70 and the rotating bracket 20. At this time, the two components forming the rotation pair between the second connection mechanism 70 and the rotating bracket 20 can be: the swing arm 73 and the rotating bracket 20. The rotation pair elements can be: the connection surface between the swing arm 73 and the rotating bracket 20 and the connection surface on the side wall 23 of the rotating bracket connected to the swing arm 73.

[0126] Specifically, in some embodiments, when the lifting device 100 is not subjected to an impact force, the first stopper 40 limits the swing arm 73 from rotating relative to the rotating bracket 20, that is, the swing arm 73 and the seat body 75 are both fixed relative to the rotating bracket 20. Fig.11 If the tilting device 100 needs to be tilted, the power mechanism 30 can drive the rotating bracket 20 to rotate relative to the fixed bracket 10 to tilt, so that the propeller 200 can adjust the tilting angle. At this time, the first end 31 of the power mechanism can rotate relative to the fixed bracket 10, and the second end 33 of the power mechanism can rotate relative to the rotating bracket 20. In the case that the tilting device 100 is subjected to impact force, the first limiter 40 releases the restriction on the swing arm 73, and the first limiter 40 allows the swing arm 73 to rotate relative to the rotating bracket 20. Compared with the power mechanism 30 driving the rotating bracket 20 to rotate relative to the fixed bracket 10 to tilt, the swing arm 73 rotates relative to the rotating bracket 20 to release the impact force on the tilting device 100, thereby preventing the structure of the tilting device 100 from being damaged.

[0127] Please continue reading Figure 7 and Figure 8 In some embodiments, the seat body 75 is provided with an installation space 751 , and the second end 33 of the power mechanism is rotatably installed in the installation space 751 through the second shaft 71 .

[0128] Specifically, in some embodiments, the seat 75 may be provided with a groove, and the installation space 751 is a groove. Among them, the groove may be recessed from the seat 75 toward the side away from the power mechanism 30, and the second shaft 71 is fixedly installed in the groove. The setting of the groove can prevent the second shaft 71 from interfering with other structures, thereby improving the installation stability of the second shaft 71. In addition, the second shaft 71 is accommodated in the installation space 751, and the second end 33 of the power mechanism is connected to the second shaft 71, thereby reducing the space occupied by the power mechanism 30 and the seat 75, thereby realizing the miniaturization of the tilting device 100. In other embodiments, two spaced protrusions (not shown) may be provided on the seat 75, and the installation space 751 is the gap between the two protrusions. Among them, the protrusion may extend from the seat 75 toward the direction of the power mechanism 30, and the second shaft 71 is fixedly arranged between the two protrusions. The setting of the protrusion can prevent the second shaft 71 from interfering with other structures, thereby improving the installation stability of the second shaft 71.

[0129] In some embodiments, when the first stopper 40 restricts the second connection mechanism 70 to remain relatively fixed to the rotating bracket 20, the second connection mechanism 70 contacts the first stopper 40. When the first stopper 40 releases the restriction on the second connection mechanism 70, the portion of the first stopper 40 disposed on the rotation path of the second connection mechanism 70 and the portion fixedly connected to the rotating bracket 20 break and fail.

[0130] Specifically, when the second connection mechanism 70 contacts the first stopper 40, the first stopper 40 and the second stopper 50 can jointly clamp the seat body 75 and / or the swing arm 73 to limit the second connection mechanism 70 to remain relatively fixed with the rotating bracket 20. When the tilting device 100 is subjected to an impact force, the portion of the first stopper 40 on the rotation path of the second connection mechanism 70 and the portion fixedly connected to the rotating bracket 20 are broken, so that the second connection mechanism 70 can rotate relative to the rotating bracket 20. At this time, the failure of the first stopper 40 to break can absorb the impact force to prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the rotation of the second connection mechanism 70 relative to the rotating bracket 20 can also allow the rotating bracket 20 to rotate relative to the fixed bracket 10 together with the power mechanism 30, so that the power mechanism 30 is prevented from being affected by the impact force, and the rotating bracket 20 can be tilted to a higher angle, thereby releasing the impact force. It can be understood that the first stopper 40 can be made of a brittle metal material. The rigidity strength of the first stopper 40 is based on the ability to withstand the main body of the propeller 200 being lifted up by the power mechanism 30 driving the rotating bracket 20. The first stopper 40 is the weakest rigid component on the entire propeller 200. When an impact force occurs on the entire power transmission path of the propeller 200, the second connection mechanism 70, as the weakest rigid component, will first produce a rigid fracture, so that the first stopper 40 will fail first, and the second connection mechanism 70 will be released from the limit, thereby allowing the second connection mechanism 70 to rotate relative to the fixed bracket 10, thereby releasing the impact force and protecting other power transmission components on the propeller 200.

[0131] The specific structure of the first limiter 40 in this embodiment is similar to Figure 2 The specific structure of the first limiter 40 is basically the same, and the only difference is that:

[0132] In the case where the first stopper 40 includes a first portion 41 mounted on the rotating bracket 20, the first portion 41 is located on the rotation path of the second connecting mechanism 70, and is used to contact the second connecting mechanism 70 when the second connecting mechanism 70 rotates. Specifically, in some embodiments, the first portion 41 can be fixedly mounted on the rotating bracket 20 and at least partially located on the rotation path of the second connecting mechanism 70. When the second connecting mechanism 70 rotates, the second connecting mechanism 70 contacts the portion of the first portion 41 located on the rotation path of the second connecting mechanism 70, so that the portion of the first portion 41 located on the rotation path of the second connecting mechanism 70 and the portion fixedly connected to the rotating bracket 20 are broken, thereby absorbing the impact force and preventing the warping device 100 from being damaged. The connection method between the first portion 41 and the rotating bracket 20 includes, but is not limited to, bonding or welding, etc. In some embodiments, the portion of the first portion 41 located on the rotation path of the second connecting mechanism 70 may correspond to the swing arm 73, and when the second connecting mechanism 70 rotates, the portion of the first portion 41 located on the rotation path of the second connecting mechanism 70 may contact the swing arm 73. In other embodiments, the portion of the first part 41 located on the rotation path of the second connecting mechanism 70 may correspond to the seat body 75. When the second connecting mechanism 70 rotates, the portion of the first part 41 located on the rotation path of the second connecting mechanism 70 may contact the seat body 75.

[0133] In the case where the first stopper 40 includes a first portion 41 fixed to the rotating bracket 20 and a second portion 42 fixed to the first portion 41, the second portion 42 is located on the rotation path of the second connecting mechanism 70, and is used to contact the second connecting mechanism 70 when the second connecting mechanism 70 rotates. Specifically, in some embodiments, the second portion 42 can be sleeved on the portion of the first portion 41 located on the rotation path of the second connecting mechanism 70, and is completely located on the rotation path of the second connecting mechanism 70. When the second connecting mechanism 70 rotates, the second connecting mechanism 70 can contact the second portion 42, so that the position of the first portion 41 that is not connected to the second portion 42 is broken, thereby absorbing the impact force and preventing the tilting device 100 from being damaged. In other embodiments, the second portion 42 can be sleeved on the portion of the first portion 41 located on the rotation path of the second connecting mechanism 70, and is partially located on the rotation path of the second connecting mechanism 70. When the second connecting mechanism 70 rotates, the second connecting mechanism 70 may contact the portion of the second part 42 located on the rotation path of the second connecting mechanism 70, and the portion of the second part 42 located on the rotation path of the second connecting mechanism 70 and the portion of the second part 42 not located on the rotation path of the second connecting mechanism 70 may be broken, thereby absorbing the impact force and preventing the tilting device 100 from being damaged. In some embodiments, the portion of the second part 42 located on the rotation path of the second connecting mechanism 70 may correspond to the swing arm 73, and when the second connecting mechanism 70 rotates, the portion of the second part 42 located on the rotation path of the second connecting mechanism 70 may contact the swing arm 73. In other embodiments, the portion of the second part 42 located on the rotation path of the second connecting mechanism 70 may correspond to the seat body 75, and when the second connecting mechanism 70 rotates, the portion of the second part 42 located on the rotation path of the second connecting mechanism 70 may contact the seat body 75.

[0134] In some embodiments, the contact area between the second portion 42 and the second connection mechanism 70 is greater than the contact area between the first portion 41 and the second connection mechanism 70 when the second portion 42 is not provided. The provision of the second portion 42 can increase the contact area between the first stopper 40 and the second connection mechanism 70, thereby, on the one hand, when subjected to an impact force, the impact force can act more on the first stopper 40, thereby facilitating the breaking of the first stopper 40; on the other hand, when not subjected to an impact force, the pressure of the first stopper 40 on the second connection mechanism 70 when the second connection mechanism 70 contacts the first stopper 40 can be reduced, thereby preventing the second connection mechanism 70 from being damaged due to collision, thereby ensuring the stability of the tilting device 100.

[0135] It is understandable that, as an alternative to the above-mentioned embodiment, the first part 41 may be fixed to the rotating bracket 20, and the second part 42 may be located on the rotation path of the second connecting mechanism 70, and the first part 41 may be fixed to the second connecting mechanism 70, and the second part 42 may be located on the rotation path of the rotating bracket 20 relative to the second connecting mechanism 70. Specifically, a receiving groove is provided on the side wall 23 where the rotating bracket 20 and the second connecting mechanism 70 are rotatably matched, the first part 41 is fixed to the second connecting mechanism 70 adjacent to the receiving groove, the second part 42 is received in the receiving groove, and the second part 42 is abutted against the inner wall of the receiving groove, so that when the first part 41 and the second part 42 are not broken, the first limiter 40 can limit the second connecting mechanism 70 from being fixed relative to the rotating bracket 20. When the propeller 200 is subjected to an impact force, the first part 41 and the second part 42 are broken, the first part 41 is fixed to the second connecting mechanism 70 and will not be lost, and the second part 42 is still received in the receiving groove due to the clamping cooperation with the receiving groove and will not be lost, thereby preventing the second part 42 from falling into the water and causing damage to the propeller 215 ( Fig.11 damage shown).

[0136] Please refer again Figure 7 and Figure 8 Furthermore, in some embodiments, the rotating bracket 20 may be provided with a third limit member 19, and when the first limit member 40 releases the restriction on the second connecting mechanism 70, the third limit member 19 is used to limit the movement range of the second connecting mechanism 70.

[0137] When the first stopper 40 releases the restriction on the second connection mechanism 70, the second connection mechanism 70 can rotate relative to the rotating bracket 20, so that the power mechanism 30 rotates relative to the rotating bracket 20 along with the second connection mechanism 70, thereby releasing the impact force. Fig.11 As shown), therefore, if the rotation angle of the rotating bracket 20 relative to the fixed bracket 10 is too large, the propeller 200 ( Fig.11 The third stopper 19 can limit the movement range of the second connection mechanism 70, that is, limit the rotation range of the rotating bracket 20 relative to the fixed bracket 10, and avoid the rotating angle of the rotating bracket 20 relative to the fixed bracket 10 being too large, which may cause damage to the propeller 200.

[0138] In some embodiments, the third stopper 19 is disposed at a position where the rotating bracket 20 is rotatably connected to the rotating bracket 20 near the second connection mechanism 70. Specifically, in some embodiments, the third stopper 19 may be a protrusion protruding from the side wall 23 of the rotating bracket toward the power mechanism 30, and the third stopper 19 is disposed on the rotating bracket 20 near a position where the swing arm 73 is rotatably connected to the rotating bracket 20, so that the third stopper 19 can cooperate with the swing arm 73 to limit the range of motion of the swing arm 73.

[0139] More specifically, in some embodiments, the third limiting member 19 has a first limiting surface 191 and a second limiting surface 193. When the first limiting member 40 releases the restriction on the second connection mechanism 70, the second connection mechanism 70 rotates between the first limiting surface 191 and the second limiting surface 193. The first limiting surface 191 can limit the tilting angle of the rotating bracket 20 relative to the fixed bracket 10, thereby preventing the rotating bracket 20 from rotating too much relative to the fixed bracket 10, thereby preventing the propeller 200 from being damaged. The second limiting surface 193 can prevent the propeller 200 from colliding with the hull 1001, thereby preventing the propeller 200 from being damaged.

[0140] In other embodiments, when the first stopper 40 restricts the second connection mechanism 70 to remain relatively fixed to the rotating bracket 20, the first connection mechanism 70 contacts the first stopper 40. When the first stopper 40 releases the restriction on the second connection mechanism 70, the first stopper 40 deforms and fails. It should be noted that the structure of the tilting device 100 in this embodiment, except for the first stopper 40, is the same as the structure of the tilting device 100 shown in the figure except for the first stopper 40; the first stopper 40 in this embodiment is in contact with the first stopper 40. Figure 8 The first stopper 40 in the tilting device 100 shown is different.

[0141] Specifically, when the tilting device 100 is subjected to an impact force, the first stopper 40 may be deformed and fail, thereby causing the second connection mechanism 70 to rotate relative to the rotating bracket 20. At this time, the deformation and failure of the first stopper 40 can absorb the impact force on the tilting device 100 to prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the rotation of the second connection mechanism 70 relative to the rotating bracket 20 can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, so that the rotating bracket 20 can be tilted to a higher angle, thereby not only releasing the impact force, but also realizing the thruster 200 ( Fig.11 to avoid obstacles.

[0142] In some embodiments, the first limit member 40 may include an elastic member (not shown), one end of the first limit member 40 is fixedly connected to the second connecting mechanism 70, and the other end is fixedly connected to the rotating bracket 20, and the first limit member 40 provides elastic force to the second connecting mechanism 70 so that the second connecting mechanism 70 is connected to the rotating bracket 20.

[0143] Specifically, when the tilting device 100 is not subjected to an impact force, or the impact force on the tilting device 100 is small, the elastic force of the elastic member can connect the second connecting mechanism 70 and the rotating bracket 20, and limit the second connecting mechanism 70 to remain relatively fixed with the rotating bracket 20. When the tilting device 100 is subjected to an impact force, the impact force can overcome the elastic force generated by the elastic member to allow the second connecting mechanism 70 to rotate relative to the rotating bracket 20. When the magnitude of the impact force is greater than the tensile strength of the elastic member, the elastic member deforms and fails. Thus, the deformation and failure of the first limit member 40 can prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the rotation of the second connecting mechanism 70 relative to the rotating bracket 20 can also increase the rotation range of the rotating bracket 20 relative to the rotating bracket 20, so that the rotating bracket 20 can be tilted to a higher angle to release the impact force. In some embodiments, the elastic member can be one of a spring, a torsion spring and a tension spring, which is not limited here.

[0144] See also Fig. 9 In the fourth aspect of the tilting device 100 of the present application, the first limiter 40 is configured on the second connection mechanism 70. The first limiter 40 is used to limit the movement of the second connection mechanism 70 relative to the rotating bracket 20. When the tilting device 100 is subjected to an impact force, the first limiter 40 is also used to allow a moving pair to be formed between the second connection mechanism 70 and the rotating bracket 20. At this time, the two components forming the moving pair between the second connection mechanism 70 and the rotating bracket 20 may be: the second shaft 71 and the rotating bracket 20. The moving pair element may be: the outer surface of the second shaft 71 and the surface on the side wall 23 of the rotating bracket that contacts the outer surface of the second shaft 71.

[0145] When the tilting device 100 is subjected to an impact force, a moving pair is formed between the second connecting mechanism 70 and the rotating bracket 20, that is, the second connecting mechanism 70 is in direct contact with the rotating bracket 20 and can move relatively. Therefore, the moving pair formed between the second connecting mechanism 70 and the rotating bracket 20 can release the impact force and prevent the tilting device 100 from being damaged.

[0146] Specifically, please combine Fig.11If the first limiter is not provided for the tilting device, the rotation and tilting of the rotating bracket relative to the fixed bracket is not constrained. Therefore, when the propeller is in the propulsion state, the propeller causes continuous disordered fluctuations under the disordered fluctuations of the water flow, resulting in the inability of the power generated by the propeller to effectively drive the movement of the hull, affecting the normal operation of the movable device in the water area. Therefore, in this embodiment, the second connecting mechanism 70 is fixed relative to the rotating bracket 20 under the restriction of the first limiter 40, so that when the rotating bracket 20 is not driven to tilt by the power mechanism 30, the rotating bracket 20 can be fixed relative to the fixed bracket 10, thereby ensuring that the power generated by the propeller 200 can drive the hull 1001 to move. In addition, when the tilting device 100 is subjected to an impact force, the first limiter 40 releases the restriction on the second connecting mechanism 70, so that a moving pair is formed between the second connecting mechanism 70 and the rotating bracket 20, thereby releasing the impact force and preventing damage to the tilting device 100 and the propeller 200.

[0147] In addition, in certain embodiments, in order to prevent the driving force generated by the power mechanism 30 from being unable to be stably transmitted to the rotating bracket 20, resulting in the rotating bracket 20 being unable to rotate and tilt relative to the fixed bracket 10, after the impact force on the tilting device 100 disappears, the operator can replace the new first limit member 40, and the new first limit member 40 re-limits the second connecting mechanism 70 to remain fixed to the rotating bracket 20, so as to ensure that the power mechanism 30 can drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10.

[0148] See also Fig. 9 In some embodiments, the rotating bracket 20 may include a base 21 ( Figure 6 ) and the side wall 23 ( Figure 6 As shown in FIG. 2 , the second connection mechanism 70 is fixedly connected to the base 21 through the first stopper 40, and the second connection mechanism 70 is connected to the side wall 23 of the rotating bracket. When the first stopper 40 releases the restriction on the second connection mechanism 70, the second connection mechanism 70 moves along the side wall 23 of the rotating bracket.

[0149] Specifically, please combine Fig.11In some embodiments, when the lifting device 100 is not subjected to impact force, the first stopper 40 limits the second connection mechanism 70 from moving along the side wall 23 of the rotating bracket, that is, the second connection mechanism 70 is fixed relative to the base 21. If the propeller 200 encounters an obstacle or the propeller 200 is not needed, the power mechanism 30 can drive the rotating bracket 20 to rotate and lift relative to the fixed bracket 10, so that the propeller 200 lifts and avoids the obstacle. At this time, the second end 33 of the power mechanism can rotate relative to the base 21, and the first end 31 of the power mechanism can rotate relative to the fixed bracket 10. When the lifting device 100 is subjected to impact force, the first limit member 40 releases the restriction on the second connecting mechanism 70, and the first limit member 40 allows the second connecting mechanism 70 to move along the side wall 23 of the rotating bracket, so that the power mechanism 30 moves relative to the side wall 23 of the rotating bracket together with the second connecting mechanism 70. Compared with the power mechanism 30 driving the rotating bracket 20 to rotate relative to the fixed bracket 10 to lift, the movement of the second connecting mechanism 70 along the side wall 23 of the rotating bracket can release the impact force and prevent the structure of the lifting device 100 from being damaged.

[0150] In some embodiments, the base 21 is provided with a containing space (not shown), the second shaft 71 is located in the containing space, the first limit member 40 is connected to the second shaft 71 , and the second end 33 of the power mechanism is rotatably connected to the second shaft 71 .

[0151] Specifically, in some embodiments, the base 21 may be provided with a housing space, and the housing space may be a groove. Among them, the groove may be recessed from the base 21 toward the side away from the power mechanism 30, and the second shaft 71 may be rotatably installed in the groove. The setting of the groove can prevent the second shaft 71 from interfering with other structures, thereby improving the installation stability of the second shaft 71. In addition, the second shaft 71 is accommodated in the housing space, and the second end 33 of the power mechanism is connected to the second shaft 71, thereby reducing the space occupied by the power mechanism 30 and the base 21, thereby realizing the miniaturization of the tilting device 100. In other embodiments, two spaced protrusions (not shown) may be provided on the base 21, and the housing space is the gap between the two protrusions. Among them, the protrusion may extend from the base 21 toward the direction of the power mechanism 30, and the second shaft 71 may be rotatably arranged between the two protrusions. The setting of the protrusion can prevent the second shaft 71 from interfering with other structures, thereby improving the installation stability of the second shaft 71.

[0152] See also Fig.10 In some embodiments, when the first limit member 40 limits the movement of the second shaft 71 relative to the side wall 17 of the fixed bracket, the first limit member 40 is connected to the second shaft 71, and when the first limit member 40 allows the second shaft 71 to move relative to the side wall 17 of the fixed bracket, the first limit member 40 breaks and fails.

[0153] It should be noted that, in some embodiments, the first stopper 40 includes a screw or a pin made of a brittle material. Specifically, the first stopper 40 is provided through the base 21 and connected to the second shaft 71, so that the first stopper 40 can limit the movement of the second shaft 71 relative to the side wall 23 of the rotating bracket. When the tilting device 100 is subjected to an impact force, the first stopper 40 breaks, so that the second shaft 71 can move relative to the side wall 23 of the rotating bracket. At this time, the first stopper 40 breaks and fails to absorb the impact force to avoid the impact force from damaging the internal structure of the tilting device 100. At the same time, the movement of the second shaft 71 relative to the side wall 23 of the rotating bracket can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, so that the rotating bracket 20 can be tilted to a higher angle, thereby achieving the release of the impact force. It is understandable that the first stopper 40 can select a screw or a pin made of a brittle metal material. The rigidity of the first stopper 40 is based on the ability to withstand the main engine tilting of the propeller 200 driven by the power mechanism 30 to drive the rotating bracket 20. The first limit member 40 is the component with the weakest rigidity on the entire propeller 200. When an impact force occurs on the entire power transmission path of the propeller 200, the first limit member 40, as the component with the weakest rigidity, will first produce rigid fracture, so that the first limit member 40 will fail first, thereby releasing the limit on the second connecting structure 70, and then allowing the second connecting structure 70 to rotate relative to the rotating bracket 20, thereby releasing the impact force and protecting other power transmission components on the propeller 200.

[0154] The specific structure of the first limiter 40 in this embodiment is similar to Figure 6 The specific structure of the first limiter 40 is basically the same, and the only difference is that:

[0155] When the first limiting member 40 passes through the base 21 and is connected to the second shaft 71, the groove 43 does not extend into the interior of the second shaft 71, but is located outside the first shaft 61, thereby ensuring that the impact force received by the tilting device 100 can be concentrated on the groove 43, thereby ensuring that the first limiting member 40 can break and fail, so as to achieve the movement of the second shaft 71 relative to the side wall 23 of the rotating bracket.

[0156] In some embodiments, the extension direction of the first stopper 40 is consistent with or perpendicular to the extension direction of the second shaft 71. The extension direction of the first stopper 40 is the direction in which the first end 45 of the first stopper points to the second end 47 of the first stopper. When the first stopper 40 penetrates the side wall 23 and the base 21 of the rotating bracket and extends into the accommodating space to connect with the second shaft 71, the extension direction of the first stopper 40 is consistent with the extension direction of the second shaft 71. In some embodiments, the base 21 includes a first side 211 and a second side 213 opposite to each other, the first side 211 of the base faces the power mechanism 30, and the first stopper 40 can penetrate the second side 213 of the base and extend into the accommodating space to connect with the second shaft 71. At this time, the extension direction of the first stopper 40 is perpendicular to the extension direction of the second shaft 71.

[0157] Since the first stopper 40 can break to absorb the impact force when the tilting device 100 is subjected to an impact force, thereby preventing the internal structure of the tilting device 100 from being damaged by the impact force, and after the impact force disappears, in order to ensure that the power mechanism 30 can still drive the rotating bracket 20 to rotate and tilt relative to the fixed bracket 10 through the first connection mechanism 60 and the second connection mechanism 70, it is necessary to replace a new first stopper 40 so that the new first stopper 40 can again limit the second connection mechanism 70 to remain relatively fixed with the rotating bracket 20. Therefore, compared with the first stopper 40 penetrating the side wall 23 and the base 21 of the rotating bracket and extending into the accommodating space to connect with the second shaft 71, the first stopper 40 penetrating the second side 213 of the base and extending into the accommodating space is convenient for the first stopper 40 to fall off after breaking, so that it is more convenient for the operator to replace the first stopper 40, simplifying the operation steps.

[0158] See also Fig. 9 and Fig.10 In some embodiments, a guide member 90 is provided on the side wall 23 of the rotating bracket, and the guide member 90 is used to guide the second shaft 71 to move relative to the rotating bracket 20.

[0159] When the second shaft 71 is able to move relative to the rotating bracket 20, the rotating bracket 20 is tilted; when the impact force on the tilting device 100 disappears, the second shaft 71 can fall back in the opposite direction relative to the rotating bracket 20. The setting of the guide member 90 can limit the movement of the second shaft 71 relative to the rotating bracket 20, thereby preventing the rotating bracket 20 from rotating too much relative to the fixed bracket 10, resulting in the propeller 200 ( Fig.11 shown) and hull 1001 ( Fig.11 on the other hand, it can prevent the second shaft 71 from separating from the power mechanism 30, thereby ensuring the normal operation of the warping device 100.

[0160] In some embodiments, the guide member 90 is a groove 91 provided on the side wall 23 of the rotating bracket, and one end of the second shaft 71 extends into the groove 91. Specifically, one end of the second shaft 71 can move relative to the rotating bracket 20 in the groove 91. The guide member 90 is a groove 91 provided on the side wall 17 of the fixed bracket, so that the tilting device 100 can guide the second shaft 71 without providing too many structural parts, thereby simplifying the installation steps of the tilting device 100.

[0161] In some embodiments, the guide member 90 is mounted on the side wall 23 of the rotating bracket, and the guide member 90 is provided with a groove 91, and one end of the second shaft 71 extends into the groove 91. Specifically, one end of the second shaft 71 can move relative to the rotating bracket 20 in the groove 91. In some embodiments, the guide member 90 and the side wall 23 of the rotating bracket can be connected by a non-detachable connection method such as bonding or welding, so as to prevent the guide member 90 from falling off when the second shaft 71 moves relative to the rotating bracket 20, thereby ensuring the working stability of the tilting device 100. In other embodiments, the guide member 90 and the side wall 23 of the rotating bracket can be connected by a detachable connection method such as a threaded connection or a snap connection, so that when the guide member 90 is damaged (for example, collision wear or corrosion, etc.), it can be easily disassembled for replacement.

[0162] Please continue reading Fig. 9 and Fig.10 In some embodiments, the second shaft 71 includes a body 711, a protrusion 713 disposed at one end of the body 711, and a wear-resistant member 715. The protrusion 713 extends into the guide member 90. The wear-resistant member 715 is sleeved on the protrusion 713 and is located between the guide member 90 and the body 711.

[0163] Specifically, in some embodiments, the main body 711 can be rotatably connected to the second end 33 of the power mechanism, and the protrusion 713 extends into the groove 91. When the second shaft 71 moves relative to the side wall 23 of the rotating bracket, the protrusion 713 can move in the groove 91. Among them, the provision of the wear-resistant part 715 can reduce the wear between the main body 711 and the guide member 90, thereby extending the service life of the second shaft 71 and reducing the cost of use. It should be noted that, in some embodiments, a roller can be provided on the second shaft 71, and the roller is sleeved on the protrusion 713 and can move in the groove 91. The provision of the roller can ensure the stability of the movement of the second shaft 71 relative to the side wall 23 of the rotating bracket, and reduce or even avoid the problem of the protrusion 713 getting stuck in the groove 91.

[0164] In other embodiments, when the first stopper 40 limits the movement of the second shaft 71 relative to the side wall 17 of the fixed bracket, the first stopper 40 is connected to the second shaft 71, and when the first stopper 40 allows the second shaft 71 to move relative to the side wall 17 of the fixed bracket, the first stopper 40 is deformed and fails. Fig. 9 and Fig.10 The structure of the tilting device 100 shown in the figure is the same except for the first limiter 40; Fig. 9 and Fig.10 The first stopper 40 in the tilting device 100 shown is different.

[0165] Specifically, when the tilting device 100 is subjected to an impact force, the first stopper 40 can be deformed and fail, so that the second shaft 71 can move relative to the side wall 23 of the rotating bracket. At this time, the first stopper 40 deforms and fails to absorb the impact force on the tilting device 100 to prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the second shaft 71 can move relative to the side wall 23 of the rotating bracket to release the impact force, and can also achieve the tilting of the rotating bracket 20 to drive the propeller 200 to tilt and avoid obstacles.

[0166] It is understandable that in the above Fig. 9 and Fig.10 Based on the implementation method, a replacement implementation method is provided, in which the first limit member 40 fixed on the base 21 is replaced by the first limit member 40 fixed on the second shaft 71, and the first limit member cooperates with the base 21 to limit the second shaft 71, so as to also limit the second shaft 71 to be fixed relative to the base 21, and when the thruster 200 is subjected to impact force, the first limit member 40 breaks, thereby releasing the position restriction of the second shaft 71, so that the second shaft 71 can move relative to the base 21, thereby absorbing the impact energy.

[0167] In some embodiments, the first limiting member 40 includes an elastic member (not shown), one end of the first limiting member 40 is fixedly connected to the second connecting mechanism 70, and the other end is fixedly connected to the rotating mechanism. The first limiting member 40 provides elastic force to the second connecting mechanism 70 so that the second connecting mechanism 70 is connected to the rotating bracket 20.

[0168] Among them, when the tilting device 100 is not subjected to an impact force, or the impact force on the tilting device 100 is small, the elastic force of the elastic member can connect the second shaft 71 and the base 21, and limit the movement of the second shaft 71 relative to the base 21. When the tilting device 100 is subjected to an impact force, the impact force can overcome the elastic force generated by the elastic member to move the second shaft 71 relative to the base 21. When the magnitude of the impact force is greater than the tensile strength of the elastic member, the elastic member deforms and fails. As a result, the deformation and failure of the first limit member 40 can prevent the impact force from damaging the internal structure of the tilting device 100. At the same time, the movement of the second shaft 71 relative to the base 21 can also increase the rotation range of the rotating bracket 20 relative to the fixed bracket 10, so that the rotating bracket 20 can be tilted to a higher angle to release the impact force. In some embodiments, the elastic member can be one of a spring, a torsion spring and a tension spring, which is not limited here.

[0169] See also Figure 2 , Figure 6 , Figure 7 and Fig. 9 In some embodiments, the rotating bracket 20 is rotatably connected to the fixed bracket 10 via the third shaft 80. The third shaft 80 is provided so that when the telescopic rod 353 of the telescopic assembly 35 extends from the main body 351, the rotating bracket 20 can be pushed to rotate relative to the fixed bracket 10, thereby ensuring that the rotating bracket 20 is tilted. In some embodiments, a roller may be provided on the third shaft 80, and the roller is provided at the connection between the third shaft 80 and the fixed bracket 10.
