[0002] For ease of operation, outboard motors are often equipped with a steering handle, allowing users to adjust the motor's direction and thus change course. However, the existing steering handles are typically fixed in position relative to the main engine, or only adjustable to a few positions, leading to inconvenience. Therefore, finding a way to adjust the steering handle to any desired position to meet diverse operational needs has become a pressing technical challenge. Summary of the Invention

In a first state, the locking assembly allows the rudder handle connector to be adjusted to any position relative to the frame along a preset direction, and locks the rudder handle connector from being adjusted to the frame in the opposite direction along the preset direction. In a second state, the locking assembly allows the rudder handle connector to be adjusted to any position relative to the frame along the preset direction or in the opposite direction.

[0008] Thus, by setting a locking component that can be switched to different states between the rudder handle connector and the frame, the rudder handle connector can be infinitely adjusted to any position relative to the frame and then locked, satisfying various needs for rudder handle position adjustment.

[0072] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0073] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0074] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0076] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0077] See Figure 1 This application provides a rudder position adjustment device 100, including a frame 10, a rudder connector 20, and a locking assembly 30. The frame 10 is used for coupling with the main body of a water propulsion device. The rudder connector 20 is used for coupling with the rudder body. The locking assembly 30 connects the rudder connector 20 and the frame 10. When the locking assembly 30 is in a first state, it allows the rudder connector 20 to be adjusted to any position relative to the frame 10 along a preset direction, and locks the rudder connector 20 from adjusting its position relative to the frame 10 in the opposite direction of the preset direction. When the locking assembly 30 is in a second state, it allows the rudder connector 20 to be adjusted to any position relative to the frame 10 along the preset direction or in the opposite direction of the preset direction.

[0078] Understandably, while the rudder handle connector 20 is adjustable relative to the frame 10 in a preset direction, the locking assembly 30 can rotate relative to the rudder handle connector 20 around a certain axis. When the locking assembly 30 locks the rudder handle connector 20, it abuts against the rudder handle connector 20 and self-locks relative to the rudder handle connector 20 in the opposite direction of the preset direction, thereby restricting the adjustment of the rudder handle connector 20 relative to the frame 10. The preset direction is... Figure 2 The counter-clockwise direction of the viewpoint, i.e., the direction indicated by arrow A, is the opposite of the default direction. Figure 2 The viewing angle is clockwise, which is the opposite direction of arrow A. The rudder handle connector rotates in a preset direction to different positions, allowing the height of the controllable part of the avoidance connector to be adjusted, thus accommodating different driving positions for operators, whether seated, standing, or of different heights. After adjusting the position of the rudder handle connector, the locking component 30 locks the rudder handle connector 20, preventing it from retracting and stabilizing its control position. By unlocking the locking component 30, the rudder handle connector 20 can rotate in the opposite direction of the preset direction, thereby adjusting the control position of the rudder handle body in the opposite direction to quickly return the rudder handle connector to its initial position.

[0079] Furthermore, in an optional embodiment of this application, the locking assembly 30 has a first locking surface, and the rudder handle connector 20 has a second locking surface, with the first locking surface separably contacting the second locking surface. When the locking assembly 30 is in a first state, the first locking surface contacts the second locking surface and self-locks against the second locking surface in the opposite direction of a preset direction, thereby restricting the rudder handle connector 20 from adjusting its position relative to the frame 10 in the opposite direction of the preset direction. When the locking assembly 30 is in a second state, the first locking surface can be separated from the second locking surface or is in a critical state where relative movement is possible.

[0080] In the embodiments of this application, the first locking surface and the second locking surface are respectively disposed on two parts of the locking assembly 30 that cooperate with the rudder handle connector 20. The two cooperating parts can rotate and cooperate with each other as the rudder handle connector 20 rotates relative to the frame 10, or rotate and slide simultaneously, or slide, or roll. That is, the cooperation between the first locking surface and the second locking surface includes, but is not limited to, rotational cooperation, sliding cooperation, and rolling cooperation.

[0081] In an optional embodiment of this application, the locking component 30 may be connected to an operating element, which includes, but is not limited to, a knob, a paddle, a protrusion, a push rod, a handle, etc., for applying external force to the locking component 30, driving the locking component 30 to separate the first locking surface from the second locking surface, so that the locking component 30 is in the second state.

[0082] In the embodiments of this application, the curvatures of the first locking surface and the second locking surface are different, and the first locking surface and the second locking surface are in contact in a tangential manner. When the rudder connecting member 20 rotates in different directions, the angle between the line connecting the rotation center and the tangent point of the first locking surface and the line connecting the rotation center and the tangent point of the second locking surface will change. The change of this angle can switch the first locking surface and the second locking surface between a self-locking state and a relative rotation state.

[0083] When the first locking surface and the second locking surface form a self-locking mechanism, the rotation center of the first locking surface, the rotation center of the second locking surface, and the point of tangency between the first and second locking surfaces are not collinear. The angle between the line connecting the rotation center of the first locking surface and the point of tangency to the line connecting the rotation center of the second locking surface and the point of tangency is less than the friction angle of the first locking surface at the point of tangency.

[0084] The angle of friction refers to the angle between the total reaction force (the resultant force of the normal reaction force and the maximum static friction force) and the normal force when an object is in a critical state of sliding. When the angle between the applied force and the normal force is less than the angle of friction, the object cannot slide; that is, the object and the surface it is on are in a state of frictional self-locking.

[0085] When the angle between the line connecting the rotation center and the tangent point of the first locking surface and the line connecting the rotation center and the tangent point of the second locking surface is greater than the friction angle of the first locking surface at the tangent point, the first locking surface and the second locking surface can rotate relative to each other.

[0086] Furthermore, the locking assembly 30 is elastically connected to the frame 10 so that the locking assembly 30 can detachably contact the rudder connecting member 20, thereby enabling the locking assembly 30 to switch between a first state and a second state.

[0087] The elastic element on the locking assembly 30 applies an elastic force to the locking assembly 30 against the rudder handle connector 20, allowing the locking assembly 30 to engage with the rudder handle connector 20 without requiring active force. This allows the rudder handle connector 20 to achieve locking or unlocking engagement simply by changing its rotation direction. The elastic element can be any type of torsion spring, rectangular spring, or disc spring.

[0088] In one embodiment of this application, please refer to Figure 1 and Figure 2 The rudder handle connector 20 includes a pusher 22 and a rotating part 21 connected together. The pusher 22 is used to couple the rudder handle body so that the rudder handle connector 20 is relatively fixed to the rudder handle body. The coupling method between the pusher 22 and the rudder handle body includes, but is not limited to, threaded connection, indirect connection, direct connection, snap-fit, etc., as long as it can keep the rudder handle connector 20 relatively fixed to the rudder handle body. The rudder handle body includes, but is not limited to, a handle, an operating lever, a wheel, etc. The locking assembly 30 includes a limiting wheel 32, which is disposed on the frame 10. The limiting wheel 32 has a rotating hole 33, and the rotating part 21 is rotatably connected to the frame 10 and disposed in the rotating hole 33. The rotating part 21 is detachably coupled to the inner wall of the rotating hole 33. When the limiting wheel 32 is in the first state, the rotating part 21 can be adjusted to any position relative to the frame 10 in a preset direction, and the rotating part 21 is locked in the opposite direction relative to the frame 10. When the limiting wheel 32 is in the second state, the rotating part 21 can be adjusted to any position relative to the frame 10 along a preset direction or in the opposite direction of the preset direction.

[0089] In this embodiment, the first state is that the limiting wheel 32 can be adjusted relative to the frame 10 in a preset direction, but cannot be adjusted relative to the frame 10 in the opposite direction of the preset direction. The second state is that the limiting wheel 32 can be adjusted relative to the frame 10 in a preset direction or in the direction of the preset direction. When the pushing part 22 is adjusted relative to the frame 10 in a preset direction, the rotating part 21 can separate from the inner wall of the rotating hole 33 or be in a critical state of relative rotation; when the pushing part 22 has a tendency to move relative to the frame 10 in the opposite direction of the preset direction, the rotating part 21 can self-lock with the inner wall of the rotating hole 33. Based on this, when the limiting wheel 32 is in the first state, if the rotating part 21 adjusts its position relative to the frame 10 along a preset direction, the limiting wheel 32 does not restrict the movement of the rotating part 21; if the rotating part 21 has a tendency to adjust its position relative to the frame 10 in the opposite direction of the preset direction, the rotating part 21 and the inner wall of the rotating hole 33 self-lock, and the movement of the limiting wheel 32 in the first state in the opposite direction of the preset direction is restricted, so the rotating part 21 is also restricted from adjusting its position relative to the frame 10 in the opposite direction of the preset direction. When the limiting wheel 32 is in the second state, if the rotating part 21 has a tendency to adjust its position relative to the frame 10 in the opposite direction of the preset direction, the limiting wheel 32 moves synchronously with the rotating part 21; if the rotating part 21 adjusts its position relative to the frame 10 along the preset direction, since the limiting wheel 32 is separated from the rotating part 21 or is in a critical state where it can rotate relative to it, and the movement of the limiting wheel 32 along the preset direction is not restricted, the rotating part 21 can be adjusted to any position relative to the frame 10 along the preset direction. The rudder position adjustment device 100 also includes an unlocking component 41 for switching the limit wheel 32 to the first state or the second state.

[0090] In the embodiments of this application, the pushing part 22 can be locked to the rudder main body by fasteners such as bolts, and the rotating part 21 is integrated with the pushing part 22. The user can push the rudder main body, thereby driving the pushing part 22 and the rotating part 21 of the rudder connecting member 20 to move synchronously; when the movement of the rotating part 21 is restricted, the restriction effect can also be transmitted to the rudder main body through the pushing part 22. By switching the state of the limit wheel 32, the rotating part 21 can be adjusted to any position relative to the frame 10 and then locked, thereby realizing stepless adjustment of the position of the rudder main body and meeting various needs for rudder position adjustment.

[0091] Further, the locking assembly 30 includes a first locking block 31. One end of the first locking block 31 is rotatably connected to the rotating part 21, and the first locking block 31 and the rotating part 21 are rotatably connected by a rotating post 312; the other end of the first locking block 31 protrudes relative to the peripheral wall of the rotating part 21 and can be separably contacted with the inner wall of the rotating hole 33. When the first locking block 31 contacts the inner wall of the rotating hole 33, the first locking block 31 self-locks relative to the inner wall of the rotating hole 33 in the opposite direction along a preset direction. In this embodiment, along the radial direction of the limiting wheel 32, the first locking block 31 is approximately a wedge-shaped block that is wider on the outside and narrower on the inside, and the end of the first locking block 31 that protrudes relative to the peripheral wall of the rotating part 21 has a first contact surface 311. The first contact surface 311 is an eccentric curved surface. When the first locking block 31 locks itself against the inner wall of the rotating hole 33, the contact point between the first contact surface 311 and the inner wall of the rotating hole 33 is the point on the first contact surface 311 with the largest distance from the rotation center of the limiting wheel 32. Starting from this point, the distance between the first contact surface 311 and the rotation center of the limiting wheel 32 gradually decreases in the opposite direction of the preset direction, i.e., clockwise.

[0092] In this embodiment, the inner wall of the rotating hole 33 is the aforementioned first locking curved surface, which is the circumferential surface located on the inner ring of the limiting wheel 32. The first contact surface 311 is the aforementioned second locking curved surface. When the rotating part 21 drives the first locking block 31 to rotate relative to the rotating hole 33 in different directions, the relative motion trend between the first contact surface 311 and the inner wall of the rotating hole 33 changes, and the first contact surface 311 can be separated from the inner wall of the rotating hole 33.

[0093] The frame 10 includes a base 11. The rotating part 21 is generally disc-shaped and is rotatably connected to the base 11 via a pivot. The limiting wheel 32 is coaxial with the rotating part 21, meaning the limiting wheel 32 and the rotating part 21 are rotatably connected to the base 11 via the same pivot. When the rotating part 21 rotates relative to the frame 10 in a preset direction, the first contact surface 311 can separate from the inner wall of the rotating hole 33 or be in a critical state where relative rotation is possible, and the limiting wheel 32 does not restrict the movement of the rotating part 21. When the rotating part 21 has a tendency to rotate relative to the frame 10 in the opposite direction of the preset direction, the first contact surface 311 abuts against the inner wall of the rotating hole 33, and the first locking block 31 self-locks against the inner wall of the rotating hole 33 in the opposite direction of the preset direction, thereby keeping the rotating part 21 and the limiting wheel 32 relatively fixed. If the limiting wheel 32 is restricted from rotating in the opposite direction of the preset direction, the rotating part 21 is also locked.

[0094] The locking assembly 30 further includes a first elastic element 34, which is supported between the first locking block 31 and the rotating part 21. The first elastic element 34 is used to make the first locking block 31 contact the inner wall of the rotating hole 33. Specifically, the first elastic element 34 is used to apply an elastic force to the first locking block 31. When the rotating part 21 rotates relative to the frame 10 in a preset direction, the elastic force of the first elastic element 34 tends to make the first locking block 31 rotate in the opposite direction about the rotation center of the rotating part 21 in the preset direction. The first contact surface 311 of the first locking block 31 forms a dynamic friction relationship with the inner wall of the rotating hole 33 or disengages from contact. Slippage occurs between the rotating part 21 and the limiting wheel 32, and the limiting wheel 32 does not rotate synchronously with the rotating part 21. In the initial stage when the rotating part 21 starts to rotate, the limiting wheel 32 can move a short distance with the rotating part 21 under the action of friction and then remain stationary. When the rotating part 21 has a tendency to rotate in the opposite direction relative to the frame 10 along a preset direction, the elastic force of the first elastic member 34 tends to cause the first locking block 31 to rotate around the rotation center of the rotating part 21 in the preset direction until the first contact surface 311 contacts the inner wall of the rotating hole 33, and a self-locking is formed between the first contact surface 311 and the inner wall of the rotating hole 33, thereby keeping the rotating part 21 and the limiting wheel 32 relatively fixed. When the self-locking is formed between the first contact surface 311 and the inner wall of the rotating hole 33 to keep the rotating part 21 and the limiting wheel 32 relatively fixed, if the limiting wheel 32 is in the first state, neither the rotating part 21 nor the limiting wheel 32 can rotate in the opposite direction relative to the frame 10 along the preset direction; if the limiting wheel 32 is in the second state, the rotating part 21 and the limiting wheel 32 can rotate synchronously in the opposite direction along the preset direction.

[0095] Please see Figure 3 In this embodiment, optionally, when a self-locking mechanism is formed between the first contact surface 311 and the inner wall of the rotating hole 33, the first contact surface 311 and the inner wall of the rotating hole 33 are tangent at tangency point A. Tangency point A here refers to... Figure 3 The geometric features shown in the cross-section are different from those in the actual product. The contact between the first contact surface 311 and the inner wall of the rotating hole 33 may appear as a tangent due to the thickness of both. The center point O of the rotating part 21, the rotation center O1 of the first locking block 31, and the tangent point A are not collinear. The angle α between the line connecting the rotation center O1 of the first locking block 31 and the tangent point A (the line of action of the force of the rotating column 312 on the first locking block 31) and the line connecting the tangent point A and the center point O of the rotating part 21 is smaller than the friction angle φ of the first contact surface 311 on the inner wall of the rotating hole 33.

[0096] The friction angle refers to the angle between the total reaction force (the resultant force of the normal reaction force and the maximum static friction force) and the normal force when an object is in a critical sliding state. When the angle between the applied force and the normal force is less than the friction angle, the object cannot slide; that is, the object and its surface are in a frictionally self-locking state.

[0097] Specifically, in this embodiment, such as Figure 3 As shown, taking the first locking block 31 located at the top as an example, when the rotating part 21 rotates clockwise, the first locking block 31 has a tendency to rotate clockwise and maintains its position under the support of the first elastic element 34. At the same time, the friction between the first locking block 31 and the inner wall of the rotating hole 33 is to the left. At this time, the maximum static friction force is FAT as shown in the figure, and the normal support force of the inner wall of the rotating hole 33 on the first locking block 31 is FAn. The angle between the resultant force Fr of the two and the normal (the radial direction pointing to the inner wall of the rotating hole 33) is the friction angle φ. When the angle α between the line connecting the rotation center O1 of the first locking block 31 and the tangent point A and the line connecting the tangent point A and the center point O of the rotating part 21 is less than the friction angle φ, the first locking block 31 and the inner wall of the rotating hole 33 undergo frictional self-locking, and the first locking block 31 can drive the limiting wheel 32 to rotate together. When the rotating part 21 rotates counterclockwise, the first elastic element 34 will apply a force FB to the first locking block 31, causing the first locking block 31 to rotate counterclockwise around the rotation center of the rotating part 21 by a small angle (the specific size only needs to ensure that the first contact surface 311 and the inner wall of the rotating hole 33 separate after rotation) until the first locking block 31 and the inner wall of the rotating hole 33 no longer contact each other, thereby causing slippage transmission between the rotating part 21 and the limiting wheel 32, and the limiting wheel 32 does not rotate synchronously with the rotating part 21. In this way, the rotating part 21 can rotate to any position in the counterclockwise direction.

[0098] In this embodiment, optionally, the direction line of the elastic force FB of the first elastic member 34 does not pass through the rotation center O1 of the first locking block 31. This allows the elastic force FB to apply a torque to the first locking block 31, causing the first locking block 31 to rotate counterclockwise to a position where it disengages from the inner wall of the rotating hole 33 when the rotating part 21 rotates counterclockwise. When the rotating part 21 rotates counterclockwise, the first elastic member 34 is in a compressed state, applying a pushing force to the first locking block 31, causing the first locking block 31 to rotate counterclockwise to a position where it disengages from the inner wall of the rotating hole 33. When the rotating part 21 rotates clockwise, the first elastic member 34 is in a stretched state, applying a pulling force to the first locking block 31, causing the first locking block 31 to rotate clockwise to a position where it abuts against the inner wall of the rotating hole 33.

[0099] Further, please refer to Figure 2 and Figure 4The rotating part 21 is provided with a protrusion 211, which is located on one side of the connection between the first locking block 31 and the rotating part 21. In this embodiment, the connection between the first locking block 31 and the rotating part 21 is located on the disc surface of the rotating part 21, specifically on the side of the rotating part 21 facing the limiting wheel 32 along the axis of rotation. The protrusion 211 is also provided on this side surface of the rotating part 21. The first elastic member 34 connects the protrusion 211 and the first locking block 31. A groove 212 is provided on the protrusion 211. Specifically, the groove 212 is provided on the side of the protrusion 211 facing the first locking block 31, and the opening of the groove 212 faces the first locking block 31. The first elastic element 34 is partially disposed within the groove 212. The inner peripheral sidewall of the groove 212 is in clearance fit with the end of the first elastic element 34. The inner peripheral sidewall of the groove 212 restricts the radial movement of the end of the first elastic element 34, which helps to reduce the wobbling of the first elastic element 34 and keep the elastic force applied by the first elastic element 34 to the first locking block 31 stable. The first elastic element 34 can be a compression coil spring, an elastic pad (such as a pad made of rubber that can provide elastic force), or other elastic structure.

[0100] Please refer to it again. Figure 2 In the embodiments of this application, there can be multiple first locking blocks 31 (four as shown in the figure). Multiple first locking blocks 31 are spaced apart and connected to the periphery of the rotating part 21. Multiple protrusions 211 and multiple first elastic elements 34 are also provided corresponding to the multiple first locking blocks 31. By evenly arranging multiple first locking blocks 31 on the periphery of the rotating part 21 and detachably coupling them with the limiting wheel 32, it is beneficial to balance the force on the rotating part 21 when the first locking blocks 31 self-lock relative to the inner wall of the rotating hole 33, and to increase the friction between the rotating part 21 and the limiting wheel 32 during self-locking, thereby reducing the problem of self-locking failure of the rotating part 21 due to overload.

[0101] Please refer to it again. Figure 1 and Figure 2The frame 10 includes a base 11, and the rudder position adjustment device 100 further includes an unlocking member 41. The rotating part 21 is rotatably connected to the base 11, and the limiting wheel 32 is coaxial with the rotating part 21. The unlocking member 41 is movably mounted on the base 11 and is used to switch the limiting wheel 32 to either the first state or the second state. Specifically, one end of the unlocking member 41 is rotatably connected to the base 11, and the other end of the unlocking member 41 is detachably abutted against the outer periphery of the limiting wheel 32. When the unlocking member 41 abuts against the limiting wheel 32, the limiting wheel 32 is in the first state, and the unlocking member 41 restricts the limiting wheel 32 from rotating relative to the frame 10 in the opposite direction along a preset direction. When the unlocking member 41 is separated from the limiting wheel 32, the limiting wheel 32 is in the second state, and the limiting wheel 32 can rotate relative to the frame 10 to any position in either the preset direction or the opposite direction of the preset direction.

[0102] In one embodiment of this application, the outer periphery of the limiting wheel 32 is provided with a plurality of protrusions 321, and the unlocking member 41 can detachably abut against the plurality of protrusions 321. When the unlocking member 41 abuts against the plurality of protrusions 321, the limiting wheel 32 is in the first state, and the unlocking member 41 restricts the limiting wheel 32 from rotating relative to the base 11 in the opposite direction of a preset direction. When the unlocking member 41 is separated from the plurality of protrusions 321, the limiting wheel 32 is in the second state, and the limiting wheel 32 can rotate relative to the base 11 to any position in the opposite direction of the preset direction or in the preset direction.

[0103] Each protrusion 321 has an adjacent stepped surface 322 and an inclined surface 323 on its outer side, forming an acute-angle structure at the end of the protrusion 321. Multiple protrusions 321 form multiple ratchet structures on the outer periphery of the limiting wheel 32. Between adjacent protrusions 321, the stepped surface 322 of one protrusion 321 faces the inclined surface 323 of another protrusion 321, and the inclination direction of the inclined surface 323 is tangent to a preset direction. The stepped surface 322 of each protrusion 321 serves to abut against the unlocking member 41, and the inclined surface 323 assists the end of the unlocking member 41 in sliding to the next protrusion 321 during the rotation of the limiting wheel 32 in the preset direction, causing the unlocking member 41 to engage with the ratchet, thereby restricting the limiting wheel 32 from rotating relative to the frame 10 in the opposite direction along the preset direction.

[0104] Furthermore, the frame 10 also includes a second elastic member 42, which is disposed between the unlocking member 41 and the base 11. The second elastic member 42 applies an elastic force to the unlocking member 41, causing the unlocking member 41 to abut against the limiting wheel 32. When the unlocking member 41 abuts against the limiting wheel 32 under the action of the second elastic member 42, the limiting wheel 32 is in the first state. When the unlocking member 41 overcomes the elastic force of the second elastic member 42 and separates from the limiting wheel 32, the limiting wheel 32 is in the second state.

[0105] The second elastic element 42 in this embodiment includes, but is not limited to, a torsion spring. One end of the second elastic element 42 abuts against the side of the unlocking member 41 away from the limiting wheel 32, and the other end abuts against the base 11. It is used to apply an elastic force toward the limiting wheel 32 to the unlocking member 41 to press the unlocking member 41 against the protrusion 321 of the limiting wheel 32. When the limiting wheel 32 needs to switch to the second state, a torsional force can be applied to one end of the unlocking member 41 to make the unlocking member 41 rotate around the connecting shaft between the base 11 and the unlocking member 41. The unlocking member 41 moves away from the limiting wheel 32, so that the unlocking member 41 overcomes the elastic force and separates from the limiting wheel 32.

[0106] Furthermore, the frame 10 also includes a knob 43, which is connected to the unlocking member 41. The knob 43 is used to drive the unlocking member 41 to rotate, so that the unlocking member 41 separates from or contacts the limiting wheel 32. In this embodiment, the knob 43 is located on the outside of the base 11, specifically on the side of the base 11 opposite to the limiting wheel 32. The knob 43 is axially connected to the unlocking member 41. When an external force pushes the knob 43 to rotate, it can drive the unlocking member 41 to rotate synchronously, thereby causing the unlocking member 41 to overcome the elastic force and separate from the limiting wheel 32, switching the limiting wheel 32 from the first state to the second state. When the external force applied to the knob 43 is removed, the unlocking member 41 and the knob 43 can be reset under the action of the second elastic member 42. The unlocking member 41 abuts against the protrusion 321 on the outer periphery of the limiting wheel 32, switching the limiting wheel 32 from the second state to the first state.

[0107] Please see Figure 5 In another embodiment of this application, the locking assembly 30 includes a second locking block 35, one end of which is rotatably connected to the inner sidewall of the rotating hole 33, and the other end of which is detachably abuts against the outer peripheral sidewall of the rotating part 21. When the second locking block 35 contacts the outer peripheral sidewall of the rotating part 21, the second locking block 35 self-locks against the outer peripheral sidewall of the rotating part 21 in the opposite direction along a preset direction.

[0108] Specifically, the second locking block 35 abutting against one end of the rotating part 21 has a second contact surface 351, which is generally an eccentric fan-shaped arc surface. Along a preset direction, Figure 5 From right to left, the distance between the rotation center of the second locking block 35 and the second contact surface 351 gradually increases, meaning the radius of curvature of the second contact surface 351 gradually increases. When the rotating part 21 rotates relative to the frame 10 in a preset direction, the second contact surface 351 and the outer peripheral sidewall of the rotating part 21 are in a critical separation state, and the second locking block 35 does not restrict the movement of the rotating part 21. When the rotating part 21 has a tendency to rotate relative to the frame 10 in the opposite direction along the preset direction, the second contact surface 351 abuts against the outer peripheral sidewall of the rotating part 21 and self-locks with the outer peripheral sidewall of the rotating part 21. The self-locking principle is roughly the same as in the aforementioned embodiment. Figure 5 The frame 10, rudder connecting member 20, limit wheel 32, unlocking member 41, and other structures shown in the embodiment are similar to those in the previous embodiment. Figure 1 The embodiments shown are largely the same, and will not be described again here.

[0109] Furthermore, multiple second locking blocks 35 are spaced apart and connected to the inner wall of the rotating hole 33. By uniformly arranging multiple second locking blocks 35 on the inner wall of the rotating hole 33 and detachably coupling them with the rotating part 21, it is beneficial to balance the force on the rotating part 21 when the second locking blocks 35 self-lock relative to the outer wall of the rotating part 21, and to increase the friction between the rotating part 21 and the limiting wheel 32 during self-locking, thereby reducing the problem of self-locking failure of the rotating part 21 due to overload.

[0110] Please see Figure 6 In another embodiment of this application, the unlocking member 41 detachably abuts against the outer peripheral side of the limiting wheel 32 at one end. When one end of the unlocking member 41 contacts the outer peripheral sidewall of the limiting wheel 32, the unlocking member 41 self-locks against the outer peripheral sidewall of the limiting wheel 32 in the opposite direction to the preset direction, and the limiting wheel 32 is in a first state. When one end of the unlocking member 41 separates from the outer peripheral side of the limiting wheel 32, the limiting wheel 32 is in a second state.

[0111] Specifically, the outer periphery of the limiting wheel 32 is a circular surface, and the end of the unlocking member 41 that abuts against the limiting wheel 32 has an eccentric arc surface 411. The eccentric arc surface 411 abuts against the circular surface of the outer periphery of the limiting wheel 32 in a separable manner, and the other end of the unlocking member 41 is rotatably connected to the base 11. Along a preset direction, the distance between the rotation center of the unlocking member 41 and the eccentric arc surface 411 gradually increases, that is, the radius of curvature of the eccentric arc surface 411 gradually increases. When the limiting wheel 32 rotates relative to the frame 10 along the preset direction, the eccentric arc surface 411 of the unlocking member 41 is in a critical separation state from the outer periphery of the limiting wheel 32, and the unlocking member 41 does not restrict the movement of the limiting wheel 32. When the limiting wheel 32 has a tendency to rotate in the opposite direction relative to the frame 10 along a preset direction, the eccentric arc surface 411 of the unlocking member 41 abuts against the circumferential surface of the outer periphery of the limiting wheel 32 and self-locks with the outer periphery of the limiting wheel 32 to restrict the limiting wheel 32 from rotating in the opposite direction relative to the frame 10 along the preset direction. The self-locking method of the unlocking member 41 on the outer periphery of the limiting wheel 32 is similar to... Figure 1-3 The self-locking mechanism of the limiting wheel 32 and the first locking block 31 in the illustrated embodiment is roughly the same, and will not be described again here. When the unlocking member 41 separates from the limiting wheel 32 under the action of external force, the limiting wheel 32 can rotate to any position relative to the frame 10 in the opposite direction of the preset direction.

[0112] Please see Figure 7 In one embodiment of this application, the rudder handle connector 20 further includes a limiting protrusion 23, which is disposed on the side of the rotating part 21 away from the pushing part 22. The frame 10 is provided with a supporting part 12. During the rotation of the rudder handle connector 20, the supporting part 12 is used to block the limiting protrusion 23 or the pushing part 22 to limit the rotation range of the rudder handle connector 20. Specifically, the supporting part 12 protrudes from the base 11 and is spaced apart from the rotating part 21. The supporting part 12 has a first supporting surface 121 on the side facing the unlocking member 41, that is, the inner side of the supporting part 12 has a first supporting surface 121, and the end of the supporting part 12 extending out of the base 11 has a second supporting surface 122. The first supporting surface 121 and the second supporting surface 122 are angled together. When the first supporting surface 121 abuts against the limiting protrusion 23, the rudder handle connector 20 is in its initial position, at which time the operating position of the rudder handle body is at its lowest. When the rudder handle connector 20 rotates in a preset direction until the second abutment surface 122 abuts against the push part 22, the rotation angle of the rudder handle connector 20 reaches its limit position, at which point the operating position of the rudder handle body is at its highest. The first abutment surface 121 and the second abutment surface 122 are used to limit the rotation range of the rudder handle connector 20.

[0113] Please see Figure 8In one embodiment of this application, a protrusion 24 is provided on one side of the rudder handle connector 20, and the frame 10 is provided with a first limiting member 13 and a second limiting member 14. A limiting angle is formed between the first limiting member 13 and the second limiting member 14. When the rudder handle connector 20 rotates around the frame 10, the protrusion 24 moves within the limiting angle. Specifically, the protrusion 24 is provided on one side of the rudder handle connector 20 and protrudes outward along a direction parallel to the axis of rotation of the limiting wheel 32. The first limiting member 13 and the second limiting member 14 are generally rod-shaped structures and are both provided on the outer side of the base 11, that is, on the side of the base 11 away from the limiting wheel 32. The limiting angle is the included angle between the extension lines of the first limiting member 13 and the second limiting member 14. The first limiting member 13 abuts against the protrusion 24, and the rudder stick connector 20 is in the initial position. The second limiting member 14 abuts against the protrusion 24, and the rudder stick connector 20 rotates to the maximum angle position, thereby limiting the rotation range of the rudder stick connector 20 and reducing the possibility of interference between the rudder stick body or the rudder stick connector 20 and other structures, or collision with external equipment.

[0114] Please see Figure 9 and Figure 10 In another embodiment of this application, the frame 10 includes a base 11 and a retainer 16. One end of the retainer 16 is rotatably connected to the base 11, and the locking assembly 30 is disposed at the other end of the retainer 16. The rudder connecting member 20 includes a rotating part 21 and a pushing part 22 connected together. The rotating part 21 is rotatably connected to the base 11, and the retainer 16 is located between the pushing part 22 and the base 11. The locking assembly 30 is detachably abutting against the pushing part 22 and the base 11. In this embodiment, the pushing part 22 and the rotating part 21 generally form a V-shaped structure. The end of the rotating part 21 away from the pushing part 22 is rotatably connected to the base 11 via a pivot. The locking assembly 30 is located between the end of the pushing part 22 connected to the rotating part 21 and the base 11, and the locking assembly 30 is detachably abutting against the pushing part 22 and the base 11. When the locking assembly 30 is in the first state, it contacts the pushing part 22 and the base 11, and self-locks relative to the pushing part 22 and the base 11 in the opposite direction of the preset direction. At this time, the rudder handle connector 20 can rotate to any position relative to the frame 10 in the preset direction, but cannot rotate relative to the frame 10 in the opposite direction of the preset direction. When the locking assembly 30 is in the second state, it separates from the pushing part 22 and the base 11. At this time, the rudder handle connector 20 can rotate to any position relative to the frame 10 in the opposite direction of the preset direction or in the preset direction.

[0115] In this embodiment, the base 11 is provided with a bearing 17, and the rotation axis of the rotating part 21 is rotatably engaged with the bearing 17. The bearing 17 has an outer arc surface 171. Along the axial direction parallel to the rotating part 21, the pushing part 22 protrudes from the rotating part, and the outer arc surface 171 of the bearing 17 and the portion of the pushing part 22 protruding from the rotating part 21 are spaced apart. The locking assembly 30 includes a third locking block 36, which detachably abuts against the outer arc surface 171 and the portion of the pushing part 22 protruding from the rotating part 21. The third locking block 36 has a first curved surface 361 on the side facing the base 11, and the first curved surface 361 detachably abuts against the outer arc surface 171. The third locking block 36 has a second curved surface 362 on the side away from the first curved surface 361, and the second curved surface 362 detachably abuts against the portion of the pushing part 22 protruding from the rotating part 21. When the third locking block 36 is in the first state, the first curved surface 361 self-locks relative to the outer arc surface 171 in the opposite direction of the preset direction, and the second curved surface 362 self-locks relative to the pushing part 22 in the opposite direction of the preset direction. When the third locking block 36 is in the second state, the first curved surface 361 separates from the outer arc surface 171, and the second curved surface 362 separates from the pushing part 22.

[0116] In this embodiment, the second curved surface 362 is the aforementioned first locking curved surface, and the side of the pushing part 22 that abuts against the third locking block 36 (the inner side of the part of the pushing part 22 that protrudes from the rotating part 21) also has an arc surface structure, which is the aforementioned second locking curved surface.

[0117] Furthermore, the retainer 16 is rotatably connected to the base 11, and the retainer 16 is coaxial with the rotating part 21. In this embodiment, the retainer 16 is generally T-shaped. The vertical end of the T-shaped structure of the retainer 16 shares the same pivot with the rotating part 21 and is rotatably connected to the base 11, and the retainer 16 can be adjusted in position relative to the rotating part 21. The horizontal end of the T-shaped structure of the retainer 16 is rotatably connected to the third locking block 36, so that the third locking block 36 is located between the portion of the push part 22 protruding from the rotating part 21 and the base 11. In this way, the retainer 16 can adjust the position of the third locking block 36 in real time during the rotation of the rudder connecting member 20, so that the third locking block 36 remains in contact with the push part 22 and the bearing 17 on the base 11.

[0118] like Figure 9In the illustrated embodiment, a third elastic element 25 is provided between the locking assembly 30 and the retainer 16. The third elastic element 25 applies an elastic force to the locking assembly 30, keeping the first curved surface 361 in contact with the outer arc surface 171. The third elastic element 25 may be a torsion spring, sleeved at the pivot point between the third locking block 36 and the retainer 16. One end of the third elastic element 25 is connected to the third locking block 36, and the other end is connected to the retainer 16. The first curved surface 361 remains in contact with the outer arc surface 171 under the elastic torque of the third elastic element 25. A fourth elastic element 26 is provided between the retainer 16 and the base 11. The fourth elastic element 26 applies an elastic force to the retainer 16, keeping the second curved surface 362 in contact with the pushing part 22. The fourth elastic element 26 can also be a torsion spring, which is sleeved on the pivot of the retainer 16 and the base 11. One end of the fourth elastic element 26 abuts against the side of the retainer 16 away from the rudder connecting member 20, and the other end abuts against the base 11. The second curved surface 362 remains in contact with the push part 22 under the elastic torque of the fourth elastic element 26.

[0119] Please combine Figure 10 and Figure 11 In this embodiment, optionally, when the third locking block 36 forms a self-locking connection with the pushing part 22 and the bearing 17 on the base 11, that is, when the first curved surface 361 forms a self-locking connection with the outer arc surface 171, and the second curved surface 362 forms a self-locking connection with the pushing part 22, the second curved surface 362 is tangent to the inner side surface of the pushing part 22 at tangency point A, and the first curved surface 361 is tangent to the outer arc surface 171 of the bearing 17 on the base 11 at tangency point B. The curvature center O1 of the first curved surface 361, the curvature center O2 of the second curved surface 362, and tangency point A are not collinear. The curvature center O1 of the first curved surface 361, the curvature center O2 of the second curved surface 362, and tangency point B are not collinear. Tangency point A, the curvature center O2 of the second curved surface 362, and the center point O of the bearing 17 are on a straight line. The curvature center O1 of the first curved surface 361, tangency point B, and the center point O of the bearing 17 are on another straight line. The tangent points A and B mentioned here refer to... Figure 11 The geometric features shown in the cross section are different from those in the actual product. The contact between the first curved surface 361 and the outer arc surface 171, and the contact between the second curved surface 362 and the inner side of the push part 22 may appear as tangents because each part has a certain thickness.

[0120] When the pushing part 22 and the rotating part 21 rotate clockwise as shown in the figure, the third locking block 36 tends to rotate clockwise and, supported by the third elastic member 25 and the fourth elastic member 26, maintains a position in contact with the pushing part 22 and the base 11. At the same time, the friction between the second curved surface 362 and the inner side of the pushing part 22 is to the right as shown in the figure, and the friction between the first curved surface 361 and the outer circumferential surface of the bearing 17 is to the left as shown in the figure. At this time, the maximum static friction at the tangent point A is FAT as shown in the figure, and the normal support force at the tangent point A is FAn. The angle between the resultant force FAr and the normal (the direction of the line connecting the tangent point A and the curvature center O2 of the second curved surface 362) is the friction angle ψ of the tangent point A. When the angle α between the line connecting tangent point B and tangent point A (the line of action of the thrust of the third locking block 36 at tangent point A) and the line connecting tangent point A and the center point O of bearing 17 is less than the friction angle ψ, the second curved surface 362 and the inner surface of the pushing part 22 undergo frictional self-locking. The maximum static friction force at tangent point B is FBt as shown in the figure, and the normal support force at tangent point B is FBn. The angle between the resultant force FBr and the normal (the direction of the line connecting tangent point B and the curvature center O1 of the first curved surface 361) is the friction angle ψ' of tangent point B. When the angle φ between the line connecting tangent point A and tangent point B (the line of action of the thrust of the third locking block 36 at tangent point B) and the line connecting tangent point B and the center point O of bearing 17 is less than the friction angle ψ', the first curved surface 361 and the outer arc surface 171 of bearing 17 undergo frictional self-locking.

[0121] When the rudder handle connector 20 rotates counterclockwise, under the action of the second elastic element 42 and the fourth elastic element 26, the third locking block 36 rotates counterclockwise around the retainer 16 by a small angle (the specific angle only needs to ensure that after rotation, the first curved surface 361 and the outer arc surface 171 of the bearing 17, and the second curved surface 362 and the inner surface of the push part 22 are in a critical separation state). This causes the first curved surface 361 and the outer arc surface 171 of the bearing 17, and the second curved surface 362 and the inner surface of the push part 22 to form a dynamic friction relationship, thereby causing relative rotation between the third locking block 36 and the push part 22, and the bearing 17 on the base 11. In this way, the rudder handle connector 20 can rotate counterclockwise to any position.

[0122] Please refer to it again. Figure 9The frame 10 also includes a knob 43, which is axially connected to the locking assembly 30. The knob 43 is used to drive the locking assembly 30 to rotate, thereby separating the locking assembly 30 from the base 11 and the pushing part 22. Specifically, the locking assembly 30 includes two third locking blocks 36. Along the rotation axis of the third locking blocks 36, the two third locking blocks 36 are symmetrically arranged on opposite sides of the retainer 16 along the central axis, and the two third locking blocks 36 are respectively axially connected to opposite ends of a rotating shaft. This rotating shaft is rotatably connected to the retainer 16, and the two third locking blocks 36 can move synchronously. The base 11 is also provided with two bearings 17, each bearing 17 corresponding to one third locking block 36, which helps to balance the forces on the pushing part 22 and the base 11 and improve the rotational stability of the rudder connecting member 20. The knob 43 is located on the side of one of the third locking blocks 36 away from the retainer 16 and is axially connected to the third locking block 36. The shaft connection method includes, but is not limited to, the rotating shaft of the knob 43 fixedly connected to the third locking block 36. Under external force, the knob 43 can drive the two third locking blocks 36 to rotate relative to the retainer 16, causing the third locking blocks 36 to separate from the pushing part 22 and the base 11, thus switching the locking assembly 30 between the first and second states. After the external force applied to the knob 43 is removed, the third locking blocks 36 can be reset under the action of the third elastic member 25 and the fourth elastic member 26.

[0123] Please combine Figure 10 and Figure 12 The rudder handle connector 20 further includes a limiting protrusion 23, which is disposed on the side of the rotating part 21 away from the pushing part 22. The frame 10 is provided with a supporting part 12, which is disposed on the base 11 and located on the side of the rudder handle connector 20 opposite to the retainer 16. During rotation of the rudder handle connector 20, the supporting part 12 serves to abut against the limiting protrusion 23 or the rotating part 21 to limit the rotation range of the rudder handle connector 20.

[0124] Specifically, in this embodiment, the abutment portion 12 is disposed at the bottom of the base 11. The abutment portion 12 includes a first abutment surface 121 and a second abutment surface 122 arranged at an angle. The first abutment surface 121 is used to abut the limiting protrusion 23, and the second abutment surface 122 is used to abut the rotating portion 21. When the first abutment surface 121 abuts the limiting protrusion 23, the rudder connecting member 20 is in the initial position. When the second abutment surface 122 abuts the rotating portion 21 on the side away from the limiting frame, the rudder connecting member 20 rotates in a preset direction to the maximum angle position, thereby limiting the rotation range of the rudder connecting member 20.

[0125] Please see Figure 13 and Figure 14In another embodiment of this application, the third locking block 36 and the bearing 17 may also be disposed in the middle of the base 11, and the number of the third locking blocks 36 may also be one. The retainer 16 includes a support portion 161 and connecting plates 162 located on both sides of the support portion 161, the connecting plates 162 being generally triangular in structure. The bearing 17 is partially inserted between the two connecting plates 162 and connected to the connecting plates 162 via a rotating shaft. The portion of the connecting plate 162 protruding from the bearing 17 is rotatably connected to the third locking block 36, and the first curved surface 361 and the second curved surface 362 of the third locking block 36 respectively contact the outer arc of the bearing 17 and the pushing portion 22 of the rudder connecting member 20. Figure 14 and Figure 15 The embodiment shown reduces the number of parts in the machine by adjusting the structure of the retainer 16 and the base 11 and changing the installation position of the third locking block 36, which helps to simplify the installation process and reduce production costs.

[0126] Please see Figure 15 In another embodiment of this application, a fifth elastic member 27 is provided between the pushing part 22 and the retainer 16. The fifth elastic member 27 is located on the side of the locking assembly 30 opposite to the rotating part 21. The fifth elastic member 27 is used to apply an elastic force to the retainer 16, so that the first curved surface 361 remains in contact with the outer arc surface 171, and the second curved surface 362 remains in contact with the pushing part 22. In this embodiment, the fifth elastic member 27 includes, but is not limited to, a compression spring structure, used to apply elastic pressure to the retainer 16 to make the third locking block 36 contact the base 11 and the pushing part 22.

[0127] Please see Figure 16 In another embodiment of this application, along the rotation axis parallel to the rotating part 21, a protrusion 24 is provided on one side of the pushing part 22, and a first limiting member 13 and a second limiting member 14 are provided on one side of the base 11. A limiting angle is formed between the first limiting member 13 and the second limiting member 14. When the rudder connecting member 20 rotates around the frame 10, the protrusion 24 moves within the limiting angle. Specifically, the first limiting member 13 and the second limiting member 14 can be fixedly connected to the outside of the bearing 17, and the protrusion 24 is located on the outside of the connection between the pushing part 22 and the rotating part 21. When the first limiting member 13 blocks the protrusion 24, the pushing part 22 is in the initial position. When the second limiting member 14 blocks the protrusion 24, the pushing part 22 rotates counterclockwise to the maximum angle position from the perspective of the illustration.

[0128] Please see Figure 17 , Figure 18 and Figure 19In another embodiment of this application, the frame 10 includes a base 11 with a rotating hole 33. The rudder position adjustment device 100 further includes a rotating member 15, which is rotatably connected to the base 11 and partially disposed within the rotating hole 33. The rudder connecting member 20 is axially connected to the rotating member 15. A sliding groove 38 is formed between the inner wall of the rotating hole 33 and the outer wall of the rotating member 15. The locking assembly 30 is movably disposed within the sliding groove 38, which is used to switch the locking assembly 30 between the first state and the second state. In this embodiment, the locking assembly 30 includes a fourth locking block 37, which is generally cylindrical and movably disposed within the sliding groove 38. The fourth locking block 37 switches between the first and second states of the locking assembly 30 by moving to different positions within the sliding groove. When the locking assembly 30 is in the first state, the fourth locking block 37 abuts against the inner wall of the rotating hole 33 and the outer wall of the rotating member 15, and the fourth locking block 37 self-locks against the inner wall of the rotating hole 33 and the outer wall of the rotating member 15 in the opposite direction of a preset direction. When the locking assembly 30 is in the second state, the fourth locking block 37 can be separated from the inner wall of the rotating hole 33 and the outer wall of the rotating member 15, and the rotating member 15 can rotate to any position in the preset direction or in the opposite direction of the preset direction. The outer wall of the fourth locking block 37 is the aforementioned first locking curved surface, and the outer wall of the rotating member 15 is the aforementioned second locking curved surface. At this time, the rotating member 15 can serve as part of the rudder handle connecting member.

[0129] Specifically, please refer to Figure 18 and Figure 19 The sliding groove 38 includes a first section 381 and a second section 382 connected to each other. Along the radial direction of the rotating member 15, the width of the first section 381 is greater than the width of the second section 382, ​​and the width of the first section 381 is greater than the diameter of the locking assembly 30. A portion of the width of the second section 382 is less than the diameter of the locking assembly 30. That is, the width of the first section 381 is greater than the diameter of the fourth locking block 37, and the width of the second section 382 is less than the diameter of the fourth locking block 37. When the locking assembly 30 is located in the first section 381, that is, when the fourth locking block 37 is located in the first section 381, the locking assembly 30 is in the second state, and the rotating member 15 can rotate to any position along a preset direction or in the opposite direction of the preset direction. When the locking component 30 is located in the second section 382, ​​that is, when the fourth locking block 37 is located in the second section 382, ​​the locking component 30 is in the first state, and the locking component 30 self-locks against the inner wall of the rotating hole 33 and the outer wall of the rotating member 15 in the opposite direction along the preset direction.

[0130] In this embodiment, the first section 381 and the second section 382 are smoothly connected, that is, the width of the sliding groove 38 gradually decreases from the first section 381 to the second section 382. When the fourth locking block 37 moves to a position close to the second section 382 where the width is less than the diameter of the fourth locking block 37, the outer wall of the fourth locking block 37 abuts against the inner wall of the rotating hole 33 and the outer wall of the rotating member 15. The friction angle formed by the fourth locking block 37 at the contact point with the inner wall of the rotating hole 33 is greater than the angle between the thrust of the fourth locking block 37 at the contact point and the normal. The friction angle formed by the fourth locking block 37 at the contact point with the outer wall of the rotating member 15 is greater than the angle between the thrust of the fourth locking block 37 at the contact point and the normal, thereby causing the fourth locking block 37 to self-lock due to friction with the inner wall of the rotating hole 33 and the outer wall of the rotating member 15.

[0131] Furthermore, the frame 10 also includes a sixth elastic element 50 and a limiting element 60. The sixth elastic element 50 is located in the first section 381, one end of the sixth elastic element 50 is connected to the inner sidewall of the rotating hole 33, and the other end of the sixth elastic element 50 is connected to the locking assembly 30. The limiting element 60 is retractably disposed in the second section 382. When the limiting element 60 is inserted into the second section 382, ​​the limiting element 60 abuts against the fourth locking block 37, thereby limiting the fourth locking block 37 to the first section 381. When the limiting element 60 is withdrawn from the second section 382, ​​the sixth elastic element 50 is used to push the fourth locking block 37 to the second section 382. When the fourth locking block 37 moves to the second section 382 under the action of elastic force, if the rotating member 15 has a tendency to rotate in the opposite direction of the preset direction, that is, if the rotating member 15 has a tendency to rotate in the clockwise direction, the fourth locking block 37 can abut against and press the inner wall of the rotating hole 33 and the outer wall of the rotating member 15, so that the fourth locking block 37 and the rotating member 15 form a friction self-lock. The self-locking principle is roughly the same as that in the aforementioned embodiment, and will not be repeated here. When the fourth locking block 37 moves to the second section 382 under the action of elastic force, if the rotating member 15 rotates in the preset direction, that is, in the counterclockwise direction as shown in the figure, the fourth locking block 37 can move towards the first section 381 under the action of friction, or has a tendency to move towards the first section 381, so that the fourth locking block 37 can be in a critical separation state from the inner wall of the rotating hole 33 and the outer wall of the rotating member 15, thereby not restricting the rotation of the rotating member 15 in the preset direction.

[0132] In other embodiments of this application, such as Figure 20As shown, multiple positioning structures corresponding to the fourth locking block 37 can also be provided in the sliding groove 38, such as positioning protrusions 384, to limit the fourth locking block 37 to the first section 381 or the second section 382. The fourth locking block 37 can be placed in different positions in the sliding groove 38 by manually moving the fourth locking block 37, thereby switching the locking component 30 to different states.

[0133] Please refer to it again. Figure 17 , Figure 18 and Figure 19 In the embodiments of this application, the base 11 is generally rectangular in shape, and the frame 10 further includes a stationary wheel 18, which is fixedly disposed on a plane of the base 11. The rotating hole 33 is formed in the stationary wheel 18. The rotating component 15 is generally cylindrical in shape, and an irregularly shaped hole is formed at the center of the rotating component 15. The rudder handle connector 20 can be inserted into the irregularly shaped hole at the center of the rotating component 15 through a rod-like structure, so that the rudder handle connector 20 and the rotating component 15 remain relatively fixed.

[0134] The stationary wheel 18 includes a first portion 181 and a second portion 182 disposed opposite to each other. The first portion 181 and the second portion 182 are partially connected to form the stationary wheel 18. Recesses are formed at the opposite ends of the first portion 181 and the second portion 182 for mounting bolts or other fasteners to fix the stationary wheel 18 to the base 11. A rotating hole 33 is formed between the first portion 181 and the second portion 182, thereby positioning a rotating member 15 disposed in the rotating hole 33 between the first portion 181 and the second portion 182. The inner sidewall of the first portion 181 is spaced apart from the rotating member 15 to form a sliding groove 38. The inner sidewall of the second portion 182 is coaxial with the outer sidewall of the rotating member 15. Further, the inner sidewall of the second portion 182 and the outer sidewall of the rotating member 15 are clearance-fitted. The second part 182 is used to position the rotating member 15, so that the relative position between the rotating member 15 and the first part 181 is kept stable, thereby keeping the width of different sections of the sliding groove 38 stable, reducing the width change of different sections of the sliding groove 38 caused by the shaking of the rotating member 15, and affecting the self-locking effect of the device.

[0135] Along the radial direction of the stationary wheel 18, a through hole 183 is formed on one side corresponding to the second section 382, ​​and the limiting member 60 is movably disposed within the through hole 183. Specifically, the through hole 183 is formed at the top of the first part 181. The limiting member 60 is retractably disposed in the second section 382 through the through hole 183. The through hole 183 also serves to guide the movement direction of the limiting member 60, keeping the position of the limiting member 60 inserted into the sliding groove 38 stable. When the limiting member 60 is inserted into the second section 382 of the sliding groove 38 through the through hole 183, it can push the fourth locking block 37 to move to the first section 381. When the limiting member 60 remains stationary in the second section 382, ​​it can hold the fourth locking block 37 against and limit it in the first section 381.

[0136] Furthermore, the frame 10 also includes an unlocking member 41, which is connected to the limiting member 60 and movably connected to the base 11. The unlocking member 41 is used to drive the limiting member 60 into or out of the second section 382. Specifically, the unlocking member 41 is generally rod-shaped, with one end rotatably connected to the base 11 and the other end suspended, serving as a free end to facilitate the application of external force to the unlocking member 41. The rotation axis of the unlocking member 41 is parallel to the rotation axis of the rotating member 15. The end of the limiting member 60 facing away from the stationary wheel 18 can be rotatably connected to the middle section of the unlocking member 41 via a pin or similar structure. Thus, by pulling or pressing the free end of the unlocking member 41, the limiting member 60 can be moved using leverage, allowing it to be inserted into or withdrawn from the second section.

[0137] In this embodiment, the end of the limiting member 60 inserted into the second segment 382 also has a limiting recess 61. When the limiting member 60 is inserted into the second segment 382, ​​the fourth locking block 37 is partially disposed in the limiting recess 61. The curved surface structure of the limiting recess 61 can cooperate with the outer peripheral surface of the fourth locking block 37 to reduce the wobbling of the fourth locking block 37 in the first segment 381, and is used to position the fourth locking block 37.

[0138] Please see Figure 18 and Figure 21In one embodiment of this application, the sliding groove 38 further includes a third section 383. The third section 383 and the first section 381 are respectively disposed at both ends of the second section 382. Along the radial direction of the rotating member 15, the width of the third section 383 is greater than the width of the second section 382, ​​and the width of the third section 383 is greater than the diameter of the fourth locking block 37. Two locking components 30 are movably disposed within the sliding groove 38. That is, two fourth locking blocks 37 are movably disposed within the sliding groove 38. When one fourth locking block 37 is limited to the first section 381 and the other fourth locking block 37 is limited to the third section 383, the rotating member 15 can rotate relative to the base 11 in any direction. When both fourth locking blocks 37 are located in the second section 382, ​​both fourth locking blocks 37 abut against the outer wall of the rotating member 15 and the inner wall of the rotating hole 33, thereby locking the two fourth locking blocks 37 with the outer wall of the rotating member 15 and the inner wall of the rotating hole 33 along the preset direction and the opposite direction of the preset direction, so that the rotating member 15 cannot rotate relative to the base 11.

[0139] Please see Figure 22 In one embodiment of this application, the frame 10 further includes a limiting bearing 70, which is fixed within the rotating hole 33. The rotating component 15 is provided with a rotating shaft 151 that is fixedly engaged with the limiting bearing 70. The limiting bearing 70 further positions the rotating component 15 through the rotating shaft 151, thereby improving the stability of the rotating component 15 and reducing its wobbling.

[0140] In other embodiments of this application, the locking assembly 30 includes a one-way bearing connected between the rudder connecting member 20 and the frame 10, and the one-way bearing is replaceable. Figures 17 to 19 The structure shown includes the stationary wheel 18 and the fourth locking block 37. When the one-way bearing is in the first state, it allows the rudder handle connector 20 to be adjusted to any position relative to the frame 10 along a preset direction, and locks the rudder handle connector 20 from being adjusted relative to the frame 10 in the opposite direction of the preset direction. When the one-way bearing is in the second state, it allows the rudder handle connector 20 to be adjusted to any position relative to the frame 10 along the preset direction or in the opposite direction of the preset direction.

By switching the state of the locking component, the rudder body 201 can be infinitely adjusted to any position relative to the frame and then locked, satisfying various needs for rudder position adjustment.

[0143] Furthermore, the propulsion main unit 301 is used to couple a mobile water vehicle, which includes, but is not limited to, ships, rafts, and floating boards. When the water propulsion unit 300 needs to provide propulsion to the mobile water vehicle, the propeller 302 can be partially or completely submerged in the water to provide propulsion to the mobile water vehicle.

When the locking component is in the second state, the rudder body 201 can drive the rudder connecting piece to adjust to any position relative to the frame along a preset direction or in the opposite direction of the preset direction. By switching the state of the locking component, the rudder body 201 can be infinitely adjusted to any position relative to the frame and then locked, satisfying various needs for rudder position adjustment.

[0144] In embodiments of this application, the propulsion host 301 includes a mounting frame 3011 and a main body 3012 connected together.

When the rudder control body 201 is in a horizontal or downward tilted position, it is an operable position for users who are sitting or short. When the rudder control body 201 is partially housed in the support compartment 4011, it is in a non-use state.
