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, an 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 assembling portion 12 is fixedly connected with the rotating shaft 20, for example, the rotating shaft 20 is connected with the assembling portion 12 through a key. The rotation shaft 20 rotates following the rotation of the disc body 10, and in the case that the user rotates the grip portion 11, the grip portion 11 drives the assembly portion 12 to rotate, and the assembly portion 12 drives the rotation shaft 20 to rotate by a corresponding angle. The limiting piece 30 is fixedly connected with the rotating shaft 20, and the limiting piece 30 is provided with a limiting part 31. Referring to fig. 4 and 5, the locking mechanism 40 includes a driving member 41 and a driven member 42, fig. 4 illustrates a scenario in which the driven member 42 is located at a first position, and fig. 5 illustrates a scenario in which the driven member 42 is located at a second position, where the driving member 41 can drive the driven member 42 to rotate from the first position to the second position or from the second position to the first position. The follower 42 can cooperate with the limiting portion 31 at the second position to lock the rotation of the rotating shaft 20; the follower 42 is disengaged from the stopper 31 and unlocks the rotation of the rotation shaft 20 when being located at the first position.

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.

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 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 rotation number 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. 3 and 4, in some embodiments, the limiting member 30 further includes a limiting body 32, the limiting body 32 is fixedly connected with the rotating shaft 20, the number of the limiting portions 31 is plural, and the plurality of limiting portions 31 are disposed around the limiting body 32. The follower 42 can be engaged with any one of the plurality of stopper portions 31, and the steering wheel 100 is locked at different angles in response to the follower 42 being engaged with a different stopper portion 31. When the plurality of stopper portions 31 are disposed around the stopper body 32, as an example, the plurality of stopper portions 31 may be uniformly disposed around the stopper body 32. The plurality of limiting portions 31 are uniformly arranged to facilitate manufacturing and processing of the limiting member 30.

Referring to fig. 6, for example, in the case that the driven member 42 is located at the first position, the limiting body 32 can rotate relative to the driven member 42 along with the rotation of the rotating shaft 20, and the plurality of limiting portions 31 are disposed around the limiting body 32, so that the rotation of the limiting body 32 relative to the driven member 42 can switch the limiting portions 31 corresponding to the driven member 42. Fig. 6 illustrates an embodiment in which the number of the limiting parts 31 is 4, and the 4 limiting parts 31 correspond to four preset positions of 0 °, 90 °, 180 ° and 270 ° of the disc 10, respectively, when the disc 10 rotates to 90 °, the limiting part 31 corresponding to 90 ° corresponds to the position of the follower 42, and if the follower 42 is driven to move to the second position by the driving member 41 to engage with the limiting part 31, for example, the follower 42 is stopped, the driving member 41 drives the follower 42 to rotate in the counterclockwise direction to the second position capable of abutting engagement with the limiting part 31, then the steering wheel 100 can be locked at the position of 90 °. The number of the stopper portions 31 is not limited to 4, and for example, the number of the stopper portions 31 may be 2, 3, 5, 6, 7, 8 or more, which are not listed here.

In one embodiment, the follower 42 abuts against the limiting portion 31 under the driving force provided by the driving member 41, so that the follower 42 can limit the rotation of the limiting member 30. In yet another embodiment, one of the follower 42 and the limiting portion 31 is a locking structure, and the other is a locking structure, and when the follower 42 is located in the second position, the locking structure cooperates with the locking structure, so that the follower 42 can limit the rotation of the limiting member 30. In yet another embodiment, the follower 42 and the limiting portion 31 each include a magnetic attraction structure, and when the follower 42 is in the second position, the follower 42 magnetically engages with the limiting portion 31, so that the follower 42 can limit the rotation of the limiting member 30. The manner of engagement between the follower 42 and the stopper 30 is not limited to the manner of engagement exemplified in the above-described embodiment, but is not exemplified herein.

In some embodiments, the driving member 41 includes any one of an electromagnetic actuator, a motor, a cylinder, and a hydraulic cylinder, and different types of driving members 41 may be selected to provide suitable driving force according to the need, which is not limited herein.

Referring to fig. 7, in some embodiments, a limiting opening 33 is formed between every two adjacent limiting portions 31, the follower 42 is engaged with the limiting portion 31 in the limiting opening 33 when being located at the second position, and the follower 42 is disengaged from the limiting portion 31 when being located at the first position outside the limiting opening 33. That is, when the follower 42 is located at the first position, the follower 42 is located outside the stopper 33, and the stopper 31 does not interfere with the follower 42. When the follower 42 is located at the second position, the follower 42 is located in the limiting opening 33 and cooperates with the limiting portion 31 to block the limiting portion 31 from rotating relative to the follower 42. In this way, in the case where the follower 42 is located in the limiting port 33, the follower 42 can cooperate with one of the two limiting portions 31 corresponding to the limiting port 33 to limit the rotation of the limiting member 30 in the first direction, and the follower 42 can also cooperate with the other of the two limiting portions 31 corresponding to the limiting port 33 to limit the rotation of the limiting member 30 in the second direction, the first direction and the second direction being opposite rotation directions.

For example, referring to fig. 7, the driving member 41 can drive the driven member 42 to rotate to extend into or retract from the limit opening 33. In the case where the follower 42 is located in the restricting port 33, the follower 42 can be in abutting engagement with the restricting portion 31 on the left side of the restricting port 33 to restrict the rotation of the restricting member 30 in the counterclockwise direction, and the follower 42 can also be in abutting engagement with the restricting portion 31 on the right side of the restricting port 33 to restrict the rotation of the restricting member 30 in the clockwise direction to lock the steering wheel 100 at a fixed angle.

Referring to fig. 7, in some embodiments, the rotating shaft 20 can drive the limiting member 30 to rotate to switch the limiting openings 33 corresponding to the second position, each limiting opening 33 corresponds to at least one limiting angle, and the locking mechanism 40 is used for locking the rotating shaft 20 at the limiting angle corresponding to the limiting opening 33 corresponding to the second position.

For example, each limiting orifice 33 corresponds to at least one limiting angle k°, and (k+n×360°). Wherein n is the number of turns of the disk 10, n can be a positive integer, a negative integer or 0, n is a positive integer corresponding to the forward turn of the disk 10, and n is a negative integer corresponding to the reverse turn of the disk 10. When the disk 10 is rotated in the forward direction less than one full turn, n=0, and when the follower 42 engages with the stopper 33, the disk 10 can be locked at k °. When the disk 10 rotates one turn in the forward direction, n=1, and when the follower 42 engages with the stopper 33, the disk 10 can be locked at (k+360) °. When the disk 10 rotates one turn in the reverse direction, n= -1, and the follower 42 engages with the stopper 33, the disk 10 can be locked at (k-360) °.

Referring to fig. 4, in some embodiments, the limiting member 30 is a gear structure, the limiting portion 31 is a tooth of the gear structure, and a limiting opening 33 is formed between two adjacent teeth. The more the number of teeth of the gears, the more the number of limiting ports 33, the more the angle that can be limited; the smaller the number of teeth of the gear, the larger the size of the limit opening 33 between two adjacent teeth, and the easier the follower 42 can be extended into or retracted out of the limit opening 33.

Referring to fig. 4 and 5, in some embodiments, the driving member 41 can drive the driven member 42 to rotate from the first position to the second position or from the second position to the first position.

Further, in some embodiments, the plane of rotation of the follower 42 is parallel to the plane of rotation of the limiter 30. For example, referring to fig. 3, the extending direction of the rotating shaft 20 is a vertical direction, the limiting member 30 rotates in a horizontal direction along with the rotation of the rotating shaft 20, and the driven member 42 also rotates in a horizontal direction. Thus, the follower 42 rotates in the horizontal direction, which can reduce the occupation of the space in the vertical direction, and can save the space in the vertical direction.

Referring to fig. 3, in some embodiments, the height of the follower 42 and the stopper 30 in the vertical direction is substantially the same, so as to further save space in the vertical direction.

Referring to fig. 4 and 5, the driving member 41 can drive the driven member 42 to rotate around the fixing member 43 to switch between the first position and the second position.

Referring to fig. 3, in one embodiment, the rotating shaft 20 passes through the supporting member 60, and the rotating shaft 20 is connected to the supporting member 60 through a bearing, so that the rotating shaft 20 can rotate relative to the supporting member 60. The fixing member 43 is fixedly connected with the supporting member 60, and the position of the fixing member 43 on the supporting member 60 does not interfere with the rotation of the limiting member 30. The driven member 42 is rotatably connected with the fixed member 43, the driven member 42 and the limiting member 30 are basically the same in height along the vertical direction, and the driven member 42 can rotate to a second position by rotating around the fixed member 43 towards the direction close to the limiting member 30 so as to extend into the limiting port 33; the follower 42 is rotatable about the fixed member 43 in a direction away from the stop member 30 to a first position such that the follower 42 does not interfere with rotation of the stop member 30.

Referring to fig. 4, in some embodiments, the driving member 41 is disposed on the supporting member 60. In this way, the distance between the driving member 41 and the driven member 42 can be set closer, the driving member 41 can directly drive the driven member 42 to rotate, and the driving force of the driving member 41 is not transmitted by the transmission assembly, so that the number of components is saved.

In some embodiments, the driving member 41 may also be disposed outside the supporting member 60, and the driving force of the driving member 41 is transmitted to the driven member 42 through a transmission assembly. In this way, on the one hand, the space of the supporting member 60 can be saved, the supporting member 60 can be made into a smaller size, and the driving member 41 can be disposed in other idle spaces. On the other hand, the driven member 42 may be used to change the direction of the action of the driving force of the driving member 41, or to change the magnitude of the moment of the driving force, so as to apply an appropriate driving force to the driven member 42.

Referring to fig. 4 and 5, in some embodiments, the driven member 42 includes a stop member 421 and a connecting member 422, the stop member 421 is sleeved on the fixing member 43, the connecting member 422 is connected with the driving member 41, and the driving member 41 can drive the connecting portion 4271 to push or pull the stop member 421, so that the connecting member 422 drives the stop member 421 to rotate in a direction from the first position to the second position, or in a direction from the second position to the first position.

Referring to fig. 4 and 5, in one embodiment, the driving member 41 includes a driving body 411 and a driving rod 412, and the driving body 411 can drive the driving rod 412 to move toward the driving body 411 or away from the driving body 411. One end of the stopping member 421 is sleeved on the fixing piece 43 to rotate around the fixing piece 43, the tail end of the other end of the stopping member 421 is used for extending into the limiting opening 33 to be matched with the limiting portion 31, and a certain position between two opposite ends of the stopping member 421 is connected with the driving rod 412 through the connecting member 422. In the case that the disc 10 needs to be locked, the driving body 411 drives the driving rod 412 to move in the direction approaching the driving body 411, and drives the connecting member 422 to pull the stop member 421, so that the end of the stop member 421 rotates to the second position in the direction approaching the limiting member 30, and extends into the limiting opening 33. In the case that the disc 10 needs to be unlocked, the driving body 411 drives the driving rod 412 to move in a direction away from the driving body 411, and drives the connecting component 422 to push the stop component 421, so that the tail end of the stop component 421 rotates to the first position in a direction away from the limiting component 30, and the limiting port 33 is withdrawn.

Referring to fig. 3 and 8, in some embodiments, the number of followers 42 is two, and the two followers 42 are used to lock rotation of the shaft 20 in a first direction and a second direction, respectively, the first direction being opposite to the second direction. Thus, the lock mechanism 40 can lock both the forward rotation and the reverse rotation of the steering wheel 100. Wherein the forward rotation and the reverse rotation of the steering wheel 100 are respectively one and the other of the clockwise direction and the counterclockwise direction, for example, the clockwise direction may be the forward direction of the steering wheel 100, and the counterclockwise direction may be the reverse direction of the steering wheel 100; or the clockwise direction is the reverse direction of the steering wheel 100, and the counterclockwise direction is the forward direction of the steering wheel 100, which is not limited herein.

Referring to fig. 8, in one embodiment, the number of the limiting members 30 is one, two followers 42 are used to limit the rotation of the same limiting member 30, one follower 42 is used to limit the rotation of the limiting member 30 in the first direction, and the other follower 42 is used to limit the rotation of the limiting member 30 in the second direction.

For example, the first direction is clockwise and the second direction is counter-clockwise. With the rotation shaft 20 driving the stopper 30 to rotate in the clockwise direction, one of the followers 42 can rotate around the fixing member 43 in the counterclockwise direction to extend into the stopper 33 to lock the rotation shaft 20, and can rotate in the clockwise direction to withdraw from the stopper 33. In the case where the rotation shaft 20 rotates the stopper 30 in the counterclockwise direction, the other follower 42 may rotate around the fixing member 43 in the clockwise direction to extend into the stopper 33 to lock the rotation shaft 20, and may rotate in the counterclockwise direction to withdraw from the stopper 33.

Wherein the different two followers 42 correspond to different first and second positions. For example, the two followers 42 are a first follower 423 and a second follower 424, respectively. The first position corresponding to the first follower 423 only represents a position where the first follower 423 does not interfere with the limiting member 30, the second position of the first follower 423 only represents a position where the first follower 423 stops the limiting member 30 from rotating, and the rotation path of the second follower 424 does not pass through the first position and the second position corresponding to the first follower 423, so as to avoid interference between rotation of the first follower 423 and the second follower 424.

Specifically, 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 stopper 30 in the second direction is locked, so that 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 stopper 30 in the first direction is locked, so that the rotation of the rotating shaft 20 in the first 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 first position, the rotation of the stopper 30 is not limited, and the rotation shaft 20 is unlocked.

In one embodiment, the two followers 42 share the same mount 43, with one follower 42 being rotatable about the mount 43 in a first direction and the other follower 42 being rotatable about the mount 43 in a second direction. In yet another embodiment, the number of the fixing members 43 is two, and each follower 42 is rotatably connected to one fixing member 43, which is not limited herein.

Referring to fig. 3, in some embodiments, the number of the limiting members 30 is two, the rotating shaft 20 sequentially passes through the two limiting members 30, the two limiting members 30 rotate coaxially with the rotating shaft 20, each driven member 42 corresponds to one limiting member 30, and the driven member 42 can cooperate with the limiting portion 31 of the corresponding limiting member 30 to lock the rotating shaft 20 from rotating in the first direction or the second direction. The two limiting members 30 can synchronously rotate along with the rotating shaft 20, and the driven member 42 locks the rotation of any one limiting member 30 to lock the rotation of the rotating shaft 20. One of the followers 42 is used to limit rotation of the corresponding stopper 30 in the first direction, and the other follower 42 is used to limit rotation of the corresponding stopper 30 in the second direction. As such, each stopper 30 is engaged with the corresponding follower 42 only in one direction, and in the case where one follower 42 restricts the rotation of the tray 10 in one of the first direction and the second direction, the tray 10 can also be rotated in the other of the first direction and the second direction.

For example, the two stoppers 30 are a first ratchet 301 and a second ratchet 302, respectively, the stopper 31 of the first ratchet 301 is a first ratchet, the stopper 31 of the second ratchet 302 is a second ratchet, and the inclination direction of the first ratchet is opposite to the inclination direction of the second ratchet. The two followers 42 are a first pawl 425 and a second pawl 426, respectively, the first pawl 425 being rotatable in a second direction to a corresponding second position for engagement with the first ratchet to limit rotation of the first ratchet 301 in the first direction; the second pawl 426 is rotatable in the first direction to a corresponding second position that cooperates with the second ratchet teeth to limit rotation of the second ratchet 302 in the second direction. Under the condition that the rotating shaft 20 drives the first ratchet 301 and the second ratchet 302 to rotate along the first direction, the rotation direction of the second pawl 426 from the corresponding first position to the second position is also the first direction, the second pawl 426 and the second ratchet 302 rotate in the same direction, so that the second pawl 426 cannot clamp the second ratchet, the rotation direction of the first pawl 425 from the corresponding first position to the second position is the second direction, the first pawl 425 rotates opposite to the first ratchet 301, and the first pawl 425 can clamp the first ratchet to prevent the first ratchet 301 from rotating along the first direction. Similarly, in the case that the rotation shaft 20 rotates the first ratchet 301 and the second ratchet 302 in the second direction, the rotation direction of the second pawl 426 from the corresponding first position to the second position is the first direction, and the second pawl 426 rotates opposite to the second ratchet 302, so that the second pawl 426 can catch the second ratchet to prevent the second ratchet 302 from rotating in the second direction.

In one embodiment, in the case where the first pawls 425 are located at the corresponding second positions to catch the first ratchet teeth to prevent the first ratchet 301 from rotating in the first direction, if the first ratchet 301 rotates in the second direction, the limiting ports 33 corresponding to the adjacent first ratchet teeth rotate in a direction away from the first pawls 425, that is, the first ratchet 301 rotates in the second direction, so that the first pawls 425 gradually withdraw from the currently extended limiting ports 33 until falling into the next limiting ports 33, and thus the first pawls 425 cannot block the rotation of the first ratchet 301 in the second direction. When the first pawls 425 are still located at the corresponding second positions, once the first ratchet 301 rotates again in the first direction, the limiting openings 33 corresponding to the adjacent first ratchet teeth rotate in the direction approaching the first pawls 425, and when the first pawls 425 fully extend into the limiting openings 33, the rotation of the first ratchet 301 in the first direction can be locked. Similarly, with the second pawl 426 in the corresponding second position, the second ratchet wheel 302 can still rotate in the first direction. Thus, the engagement of the first pawl 425 with the first ratchet 301 is only used to lock the rotation of the rotation shaft 20 in the first direction, and the engagement of the second pawl 426 with the second ratchet 302 is only used to lock the rotation of the rotation shaft 20 in the second direction, such that the locking mechanism 40 can flexibly lock the rotation of the rotation shaft 20 in the first direction and/or the second direction.

Specifically, with the first pawl 425 in the corresponding first position and the second pawl 426 in the corresponding second position, rotation of the second ratchet 302 in the second direction is locked, such that rotation of the shaft 20 in the second direction is locked. With the first pawls 425 in the corresponding second positions and the second pawls 426 in the corresponding first positions, rotation of the first ratchet 301 in the first direction is locked, and rotation of the rotary shaft 20 in the first direction is locked. With the first pawl 425 in the corresponding second position and the second pawl 426 in the corresponding second position, rotation of the first ratchet 301 in the first direction is locked, rotation of the second ratchet 302 in the second direction is locked, and rotation of the shaft 20 in both the first and second directions is locked. With the first pawl 425 in the corresponding first position and the second pawl 426 in the corresponding first position, neither the rotation of the first ratchet 301 nor the rotation of the second ratchet 302 is locked, and the rotation shaft 20 is unlocked.

Referring to fig. 3, in some embodiments, the support 60 includes a first side 61 and a second side 62 opposite each other, the first ratchet 301 being located on the first side 61 of the support 60 and the second ratchet 302 being located on the second side 62 of the support 60. The first pawl 425 and the driver 41 for driving the first pawl 425 in rotation are located on the first side 61 of the support 60, and the second pawl 426 and the driver 41 for driving the second pawl 426 in rotation are located on the second side 62 of the support 60. In this way, the first pawl 425 and the corresponding driving member 41 and the second pawl 426 and the corresponding driving member 41 are disposed on the same supporting member 60, which can make the structure more compact. In other embodiments, the number of the supporting members 60 may be 2, one of the first ratchet 301 or the second ratchet 302 is sandwiched between the two supporting members 60, the first pawl 425 and the corresponding driving member 41 are provided to one of the supporting members 60, and the second pawl 426 and the corresponding driving member 41 are provided to the other supporting member 60.

In one embodiment, the position of the first detent 425 corresponds to the position of the second detent 426. As such, the first and second pawls 425 and 426 can share the same mount 43. For example, the securing member 43 is disposed through the first side 61 and the second side of the support member 60, the first pawl 425 is rotatably coupled to a portion of the securing member 43 located on the first side 61 of the support member 60, and the second pawl 426 is rotatably coupled to a portion of the securing member 43 located on the second side 62 of the support member 60.

In yet another embodiment, the position of the first pawl 425 is offset from the position of the second pawl 426 to facilitate weight balancing in all directions of the steering wheel 100. The number of the fixing members 43 is two, the two fixing members 43 are respectively arranged on the first side 61 and the second side of the supporting member 60, and the two driven members 42 are respectively rotatably connected with the two fixing members 43 positioned on the first side 61 and the second side of the supporting member 60.

In this way, the number of parts of the locking mechanism 40 can be saved, saving costs.

Compared with the embodiment of fig. 3, the follower 42 in the embodiment of fig. 10 does not need to rotate around the fixing member 43 with the fixing member 43 as a medium, but directly rotates around the driving member 41, so that the number of parts can be further saved.

Specifically, with the follower 42 in the first position, the first stop portion 4272 and the second stop portion 4273 are both located outside the limit opening 33, the rotation of the limiter 30 is not limited, and the rotation shaft 20 is unlocked.
