Description

Steering wheel, water area propulsion system and water area movable equipment

Technical Field

The application relates to the technical field of movable equipment in water areas, in particular to a steering wheel, a water area propulsion system and movable equipment in water areas.

Background

In the related art, the steering mechanism of the outboard motor is an external steering mechanism, namely, a steering shaft of the outboard motor is connected with one end of a rudder arm, and the other end of the rudder arm is connected with the steering shaft. The steering flexible shaft is mechanically connected with the steering wheel, and when the steering wheel rotates, the steering flexible shaft can realize reciprocating linear motion under the drive of the steering wheel so as to further drive the outboard motor to turn. However, such external steering mechanisms are susceptible to direct sea wave impacts, increasing the risk of failure. Based on this, steering of the outboard motor can be achieved using a built-in steering mechanism. However, for the built-in steering mechanism, there is no physical feedback between the outboard motor and the steering wheel, and when the outboard motor rotates to the limit position, the steering wheel can still rotate, i.e. there is a situation that the steering wheel idles and the outboard motor is not moving, so that the angle association between the steering wheel and the outboard motor fails, and the steering wheel is inaccurate in steering control of the ship.

Referring to fig. 1 to 3, the embodiment of the present application provides a steering wheel 100, and the steering wheel 100 includes a wheel body 10, a rotating shaft 20, a limiting member 30 and a locking mechanism 40. The disc 10 includes a holding portion 11 and an assembling portion 12, the holding portion 11 is used for being held by a user, the rotating shaft 20 is fixedly connected with the assembling portion 12 of the disc 10, for example, the rotating shaft 20 is connected with the assembling portion 12 through a key, and under the condition that the holding portion 11 is rotated by the user, the holding portion 11 drives the assembling portion 12 to rotate, and the assembling portion 12 drives the rotating shaft 20 to rotate by a corresponding angle. The rotation shaft 20 rotates following the rotation of the disk 10. The limiting piece 30 is fixedly connected with the rotating shaft 20, and the limiting piece 30 is provided with a limiting part 31.

The locking mechanism 40 includes a driving member 41 and a driven member 42, the driving member 41 being capable of driving the driven member 42 to move from the first position to the second position or from the second position to the first position. The follower 42 can be in friction fit with the limiting part 31 at the second position to lock the rotation of the rotating shaft 20; the follower 42 is positioned at the first position to release the friction fit with the stopper 31 and unlock the rotation of the rotation shaft 20. The friction fit produces less noise and reduces the noise of braking of steering wheel 100.

Referring to fig. 4 and 5, the first position and the second position are two positions along the moving path of the follower 42, and the driving member 41 can drive the follower 42 to switch between the first position and the second position. The first position is a position where the follower 42 is located under the condition that the follower 42 does not cooperate with the limiting portion 31 and the follower 42 does not interfere with the movement of the limiting portion 30. The second position is a position where the follower 42 is located in a case where the follower 42 can be stably engaged with the stopper 31 and the follower 42 can block the rotation of the stopper 30.

For example, the limiting portion 31 includes a first limiting portion 311 and a second limiting portion 312, and fig. 4 and 5 illustrate a scenario in which the follower 42 is located in the second position and friction-fits with the first limiting portion 311 and the second limiting portion 312. On the basis of the position of the follower 42 in fig. 5, the follower 42 (423) on the left side in fig. 5 can be moved from the second position to the first position where it is not in contact with the first stopper 311 and the second stopper 312 when the rotation shaft 20 rotates in the direction opposite to the direction in which the rotation is restricted, so as to release the friction fit of the follower 42 (423) with the first stopper 311 and the second stopper 312.

The follower 42 is located in the first position without affecting the rotation of the shaft 20, and the user can freely rotate the disc 10. The follower 42 can cooperate with the limiting portion 31 to limit the rotation of the limiting member 30 when located at the second position, and the limiting member 30 is fixedly connected with the rotating shaft 20, so that the rotation of the rotating shaft 20 can be locked due to the rotation limitation of the limiting member 30, and the disc body 10 fixedly connected with the rotating shaft 20 cannot rotate freely. In this way, the tray 10 can be locked at a certain angle.

In the related art, an electric control steering wheel can be configured on some ships, the electric control steering wheel is arranged in a ship cabin and is electrically connected with an outboard motor arranged outside the ship cabin, and the rotating angle of the electric control steering wheel can control the outboard motor to rotate by a corresponding angle, so that the steering of the ships can be controlled in the ship cabin. However, there is no physical feedback between the electrically controlled steering wheel and the outboard motor, and the steering wheel can still rotate when the outboard motor rotates to the limit position, i.e. there is a situation that the steering wheel idles and the outboard motor is not moving, so that the angle association between the steering wheel and the outboard motor fails, resulting in inaccurate control of the steering wheel on the steering of the ship.

Referring to fig. 1 to 5, the steering wheel 100 provided in the embodiment of the present application has a limiting function, and the driven member 42 is driven by the driving member 41 to move to the second position to enable the driven member 42 to cooperate with the limiting member 30, so that the number of turns and/or the rotation angle of the steering wheel 100 can be limited, and the rotation angle of the steering wheel 100 can be kept within a certain angle range. When the steering wheel 100 is used to control rotation of a corresponding steering mechanism, for example, to control rotation of an outboard motor, when the outboard motor rotates to a limit position, rotation of the steering wheel 100 is locked, so that an angle corresponding relation between the steering wheel 100 and the outboard motor can be kept unchanged, and the steering wheel 100 is prevented from idling to change the angle corresponding relation between the steering wheel 100 and the outboard motor, so that accurate angle control of the steering wheel 100 can be ensured.

Further description is provided below with reference to the accompanying drawings.

Referring to fig. 1 and 2, in some embodiments, the steering wheel 100 further includes a housing 50, and the limiting member 30, the locking mechanism 40 and the supporting member 60 are accommodated in the housing 50. The rotating shaft 20 is partially accommodated in the housing 50, and the other part passes through the housing 50 to be connected with the disk body 10 positioned outside the housing 50. The housing 50 can protect the limiter 30, the locking mechanism 40, the support 60, and the shaft 20 therein from contaminants such as liquid, dust, and the like.

Referring to fig. 4 and 5, in some embodiments, the number of the limiting portions 31 is two, including a first limiting portion 311 and a second limiting portion 312, the rotating shaft 20 is threaded through the first limiting portion 311, the second limiting portion 312 surrounds the first limiting portion 311 and is spaced apart from the first limiting portion 311, a limiting opening 33 is formed between the first limiting portion 311 and the second limiting portion 312, and in the case that the driven member 42 is located at the second position, the driven member 42 is located in the limiting opening 33 and is respectively contacted with the first limiting portion 311 and the second limiting portion 312.

With the follower 42 in the second position, the friction force between the follower 42 and the first and second stopper portions 311 and 312 can block the rotation of the stopper 30.

Referring to fig. 4 and 5, in some embodiments, when the driven member 42 is located at the first position, the first limiting portion 311 can rotate relative to the second limiting portion 312 under the driving of the rotating shaft 20. When the driven member 42 is located at the second position, the friction force between the driven member 42 and the first and second limiting portions 311 and 312 can block the first limiting portion 311 from rotating relative to the second limiting portion 312, so as to block the rotation of the limiting member 30, and lock the rotation of the rotating shaft 20.

Referring to fig. 4 and 5, in one embodiment, the first limiting portion 311 is fixedly connected to the rotating shaft 20, the second limiting portion 312 is connected to the supporting member 60, and the supporting member 60 is rotatably connected to the rotating shaft 20, so that the first limiting portion 311 can rotate relative to the second limiting portion 312.

Referring to fig. 3 to 5, in still another embodiment, the limiting member 30 further includes a housing 36, the housing 36 is connected to the supporting member 60, and the rotating shaft 20 passes through the housing 36. The housing 36 is provided with an accommodating space 361, the first limiting portion 311 and the second limiting portion 312 are located in the accommodating space 361, the second limiting portion 312 is fixedly connected with a side wall of the accommodating space 361, and as an example, the second limiting portion 312 may be in interference fit with the side wall of the accommodating space 361. The housing 36 can protect the first limiting portion 311 and the second limiting portion 312, and can provide a mounting location for the driving member 41 and/or the driven member 42, for example, the driving member 41 can be mounted to the housing 36.

For example, the first limiting portion 311 and the second limiting portion 312 are steel sleeves, the rotating shaft 20 is a rotating shaft, the first limiting portion 311 is press-fitted on the rotating shaft in an interference manner, and the second limiting portion 312 is press-fitted on a side wall of the accommodating space 361 of the housing 36 in an interference manner. In this way, the first limiting portion 311 can rotate relative to the second limiting portion 312. In other embodiments, the first limiting portion 311 and the second limiting portion 312 are not limited to steel materials, but may be other metal materials, alloy materials, etc., which are not limited herein.

Referring to fig. 5, in some embodiments, the limiting opening 33 includes a wide side 331 and a narrow side 332, the distance between the first limiting portion 311 and the second limiting portion 312 on the wide side 331 is greater than the distance between the narrow side 332 and the first limiting portion 311, the driving member 41 can drive the driven member 42 to move from the wide side 331 to the narrow side 332 into the second position to limit the rotation of the rotating shaft 20 in one of the first direction and the second direction, and the rotation of the rotating shaft 20 in the other of the first direction and the second direction can drive the driven member 42 to move from the narrow side 332 to the wide side 331 into the first position, and the first direction and the second direction are opposite.

In one embodiment, the first limiting portion 311 and the second limiting portion 312 are both circular, and the second limiting portion 312 surrounds the first limiting portion 311 and is eccentrically disposed with respect to the first limiting portion 311, so that the spacing between different positions of the first limiting portion 311 and the second limiting portion 312 is inconsistent, and thus the limiting opening 33 between the first limiting portion 311 and the second limiting portion 312 forms a wide side 331 and a narrow side 332. For example, the front projection of the first limiting portion 311 along a plane perpendicular to the rotation center axis of the rotation shaft 20 is circular, the center axis of the first limiting portion 311 coincides with the rotation center axis of the rotation shaft 20, the front projection of the second limiting portion 312 along a plane perpendicular to the rotation center axis of the rotation shaft 20 is circular, and the center axis of the second limiting portion 312 is deviated from the rotation center axis of the rotation shaft 20, so that the center axis of the first limiting portion 311 is deviated from the center axis of the second limiting portion 312, and the distances between different positions of the first limiting portion 311 and the second limiting portion 312 along the circumferential direction are different, so that the limiting opening 33 between the first limiting portion 311 and the second limiting portion 312 forms the wide side 331 and the narrow side 332. The first limiting portion 311 and the second limiting portion 312 are circular, so that the first limiting portion 311 and the second limiting portion 312 can be conveniently produced. Of course, in other embodiments, the central axis of the first limiting portion 311 may be offset from the rotation central axis of the rotation shaft 20, and the central axis of the second limiting portion 312 may be coincident with the rotation central axis of the rotation shaft 20, so long as the central axis of the first limiting portion 311 is offset from the central axis of the second limiting portion 312.

In yet another embodiment, the first limiting portion 311 is circular, the second limiting portion 312 is elliptical, and no matter whether the central axis of the second limiting portion 312 is deviated from the central axis of the first limiting portion 311, there is a region with relatively larger spacing and relatively smaller spacing between the first limiting portion 311 and the second limiting portion 312, i.e. a wide side 331 and a narrow side 332 are formed. Thus, the central axes of the first limiting portion 311 and the second limiting portion 312 can be overlapped with the rotation central axis of the rotating shaft, so that the first limiting portion 311 and the second limiting portion 312 can be assembled conveniently.

The shapes of the first and second stopper portions 311 and 312 are not limited to the circular and oval shapes of the above embodiments, and the wide side 331 and the narrow side 332 may be formed as long as the shapes of the first and second stopper portions 311 and 312 satisfy the condition that there are areas of different pitches between the first and second stopper portions 311 and 312.

Referring to fig. 5, in some embodiments, when the follower 42 is located at the first position, the follower 42 is located at the wide side 331, and the follower 42 does not interfere with the rotation of the first limiting portion 311 relative to the second limiting portion 312. Assuming that the driving member 41 drives the driven member 42 to move in the first direction from the wide side 331 to the narrow side 332, as the driven member 42 moves in the first direction, the distance between the first and second stopper portions 311 and 312 becomes gradually smaller, so that the driven member 42 is gradually brought into contact with the first and second stopper portions 311 and 312. Under the condition that the driven member 42 is in contact with both the first limiting portion 311 and the second limiting portion 312, along with the movement of the driven member 42 along the first direction, the friction force between the first limiting portion 311 and the second limiting portion 312 and the driven member 42 gradually increases, when the driven member 42 moves to the second position along the first direction, the friction force between the first limiting portion 311 and the second limiting portion 312 and the driven member 42 makes the driven member 42 unable to move in a narrower position, that is, the driven member 42 cannot continue to move along the first direction, at this time, if the first limiting portion 311 can rotate along the first direction, the force provided by the rotation of the first limiting portion 311 along the first direction drives the driven member 42 to continue to move along the first direction, and the driven member 42 cannot continue to move along the first direction under the influence of the friction force, so that the rotation of the first limiting portion 311 along the first direction is limited. If the driving force of the driving member 41 acting on the driven member 42 is removed when the driven member 42 moves to the second position along the first direction, and the first limiting portion 311 rotates along the second direction, the force provided by the rotation of the first limiting portion 311 along the first direction to the driven member 42 drives the driven member 42 to move along the second direction, that is, drives the driven member 42 to move to a wider position, so that the driven member 42 can move from the narrow side 332 to the wide side 331 to enter the first position.

Similarly, if the follower 42 is positioned at the position of the stopper 33 such that the follower 42 can move in the second direction from the wide side 331 to the narrow side 332, the follower 42 can block the first stopper 311 from moving in the second direction when in the second position. When the rotation shaft 20 drives the first limiting portion 311 to move along the first direction, the first limiting portion 311 can drive the follower 42 to move from the narrow side 332 to the wide side 331.

Referring to fig. 3 to 6, fig. 6 is an assembly schematic diagram of the steering wheel 100 with the housing 36 and the second limiting portion 312 removed based on the structure of the steering wheel 100 of fig. 4. In some embodiments, the driving member 41 includes a driving body 411 and a moving rod 413, the moving rod 413 is connected to the driving body 411, the driven member 42 includes a roller 428 and a pushed member 429, the roller 428 is connected to the pushed member 429, and the pushed member 429 is rotatably connected to the rotating shaft 20.

The driving body 411 can drive the moving rod 413 to move to a locking position far away from the driving body 411 relative to the driving body 411, so that the moving rod 413 pushes the pushed piece 429 to drive the roller 428 to roll around the rotating shaft 20 in the limiting opening 33, so that the roller 428 moves from the wide side 331 to the narrow side 332 to enter the second position, and rotation of the rotating shaft 20 in one of the first direction and the second direction is limited. The driving body 411 can also drive the moving rod 413 to move to an unlocking position close to the driving body 411 relative to the driving body 411, when the moving rod 413 is located at the unlocking position, the driving force for driving the follower 42 to move to the narrow side 332 is cancelled, and rotation of the rotating shaft 20 in the other direction of the first direction and the second direction can drive the first limiting portion 311 to rotate, so that the first limiting portion 311 drives the roller 428 to roll in the limiting opening 33, and the roller 428 moves from the narrow side 332 to the wide side 331 to enter the first position.

Referring to fig. 4, in some embodiments, the support member 60 includes a first side 61 and a second side 62 opposite to each other, the first limiting portion 311 and the second limiting portion 312 are located on the first side 61 of the support member 60, and the driving member 41 is located on the second side 62 of the support member 60. Referring to fig. 5 and 6, the supporting member 60 is provided with a through hole 64 penetrating the first side 61 and the second side of the supporting member 60, the through hole 64 is communicated with the limiting opening 33, the pushed member 429 is located on the second side 62 of the supporting member 60, one end of the roller 428 is connected with the pushed member 429 on the second side 62 of the supporting member 60, and the other end of the roller 428 penetrates through the through hole 64 and extends into the limiting opening 33. In this way, the stopper 30 and the locking mechanism 40 are compact, which is advantageous for downsizing the steering wheel 100.

Referring to fig. 5, in some embodiments, the first limiting portion 311 and the second limiting portion 312 are fixedly connected to the rotating shaft 20. That is, the rotation of the rotating shaft 20 can drive the first limiting portion 311 and the second limiting portion 312 to rotate synchronously. For example, the first limiting portion 311 is directly fixedly connected with the rotating shaft 20, the second limiting portion 312 is fixedly connected with the supporting member 60, and the supporting member 60 is fixedly connected with the rotating shaft 20, so that the rotating shaft 20 can rotate to drive the first limiting portion 311 and the second limiting portion 312 to rotate synchronously. In the case where the follower 42 is located at the second position, the friction force between the follower 42 and the first and second stopper portions 311 and 312 blocks the rotation of the first and second stopper portions 311 and 312 to lock the rotation of the rotation shaft.

Referring to fig. 5, in one embodiment, the limiting opening 33 includes a wide side 331 and a narrow side 332, a distance between the first limiting portion 311 and the second limiting portion 312 at the wide side 331 is greater than a distance between the narrow side 332, and the driving member 41 can drive the driven member 42 to switch between the first position and the second position. Follower 42 is positioned outside of limit port 33 in the case of the first position and follower 42 is positioned within limit port 33 in the case of the second position, e.g., follower 42 is movable in a direction perpendicular to the page to enter or withdraw limit port 33. With the follower 42 positioned in the limiting opening 33, rotation of the rotating shaft 20 in one of the first direction and the second direction drives the first limiting portion 311 and the second limiting portion 312 to rotate relative to the follower 42, so that the follower 42 enters the narrow side 332 to be in friction fit with the first limiting portion 311 and the second limiting portion 312, rotation of the rotating shaft 20 in the other of the first direction and the second direction can enable the follower 42 to enter the wide side 331 from the narrow side 332 to enable the follower 42 to be withdrawn from the limiting opening 33, and the first direction and the second direction are opposite.

That is, in the case that the follower 42 is located in the limiting opening 33, the rotation of the first limiting portion 311 and the second limiting portion 312 by the rotating shaft 20 can change the positional relationship between the wide side 331 and the narrow side 332 and the follower 42, for example, the follower 42 enters the narrow side 332 from the wide side 331 or enters the wide side 331 from the narrow side 332. If the rotation of the rotation shaft 20 in the first direction makes the follower 42 enter the narrow side 332 from the wide side 331 to reach the second position, when the follower 42 is located at the second position, the follower 42 cannot enter the narrower position because the follower 42 is influenced by the friction force of the first limiting portion 311 and the second limiting portion 312, so that the rotation of the rotation shaft 20 in the first direction is limited, and when the follower 42 is located at the second position, the rotation of the rotation shaft 20 in the second direction can make the follower 42 enter the wider position. Similarly, if rotation of the shaft 20 in the second direction causes the follower 42 to move from the wide side 331 to the narrow side 332 to the second position, rotation of the shaft 20 in the second direction can be restricted when the follower 42 is in the second position, and rotation of the shaft 20 in the first direction can cause the follower 42 to move from the narrow side 332 back to the wide side 331. Thus, the driving member 41 can limit the rotation of the rotating shaft 20 along one of the first direction and the second direction only by sending the driven member 42 into the limiting opening 33; and rotation of the shaft 20 in the other of the first and second directions can return the follower 42 to the wide side 331 so that the follower 42 can be withdrawn from the restricting orifice 33.

Referring to fig. 5, in some embodiments, the number of followers 42 is two, including a first follower 423 and a second follower 424, the first follower 423 and the second follower 424 being disposed at one end capable of moving in a first direction from the wide side 331 into the narrow side 332, and at the other end capable of moving in a second direction from the wide side 331 into the narrow side 332, respectively. Specifically, in the case where the first follower 423 and the second follower 424 are both located at the corresponding first positions, the rotation of the first limiting portion 311 relative to the second limiting portion 312 is not limited, and the rotation shaft 20 is unlocked. In the case where the first follower 423 and the second follower 424 are located at the corresponding first positions, the rotation of the first limiting portion 311 relative to the second limiting portion 312 in the first direction and the second direction is limited, and the rotation of the rotating shaft 20 in the first direction and the second direction is locked. When the first follower 423 is located at the corresponding first position and the second follower 424 is located at the corresponding second position, the rotation of the first limiting portion 311 relative to the second limiting portion 312 in the second direction is limited, and the rotation of the rotating shaft 20 in the second direction is locked. When the first follower 423 is located at the corresponding second position and the second follower 424 is located at the corresponding first position, the rotation of the first limiting portion 311 relative to the second limiting portion 312 in the first direction is limited, and the rotation of the rotating shaft 20 in the first direction is locked. In this manner, rotation of the disk 10 in the first direction and/or the second direction may be selectively locked.

Referring to fig. 1 and 2, in some embodiments, the steering wheel 100 further includes a bottom cover 92, and the bottom cover 92 is connected to the bottom of the housing 50 for closing the bottom of the housing 50.
