[0037] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this application.

[0038] Please see Figures 1 to 4This utility model provides an operating device. The operating device 100 includes a control lever 110, a ratchet 120, a pawl 130, an operating element 140, and an elastic element 150. The control lever 110 is rotatably connected to the body 210 of the water propeller 200. The ratchet 120 is connected to one of the control lever 110 and the body 210. The axis of the ratchet 120 is coaxial with the axis of rotation of the control lever 110 relative to the body 210. The ratchet 120 has a plurality of ratchet teeth 121, each of which limits the rotational position of the control lever 110 relative to the body 210. The pawl 130 has a first end 131 that engages with the plurality of ratchet teeth 121 and a second end 132 opposite to the first end 131. The second end 132 is movably connected to the other of the control lever 110 and the body 210. The movement of the second end 132 causes the first end 131 to engage or disengage with the ratchet teeth 121. An operating element 140 is operably connected to either the control lever 110 or the body 210 connected to the pawl 130. The operating element 140 is connected to the second end 132 via a transmission mechanism 160. The operating element 140 has a first operating position and a second operating position. An elastic element 150 elastically acts on the pawl 130, providing an elastic force for the first end 131 to engage with the ratchet 121. In the first operating position, the operating element 140 overcomes the elastic force of the elastic element 150 and, via the transmission mechanism 160, causes the first end 131 of the pawl 130 to separate from the ratchet 121, allowing the control lever 110 to rotate freely relative to the body 210. In the second operating position, the operating element 140 releases its drive to the transmission mechanism 160, and the pawl 130, driven by the elastic force of the elastic element 150, engages with a portion of the ratchet 121 through its first end 131, thus fixing the control lever 110 relative to the body 210.

[0039] Understandably, when the operating member 140 is in the first operating position, it overcomes the elastic force of the elastic member 150 and, through the transmission mechanism 160, drives the first end 131 of the pawl 130 to separate from the ratchet 121, allowing the control lever 110 to rotate freely relative to the body 210. This enables the control lever 110 to have an adjustable posture relative to the body 210. After the posture adjustment of the control lever 110 is completed, the operating member 140 can be placed in the second operating position. At this time, the operating member 140 releases its drive to the transmission mechanism 160, and the pawl 130, driven by the elastic force of the elastic member 150, engages its first end 131 with part of the ratchet 121, thus fixing the control lever 110 relative to the body 210 and maintaining the adjusted posture. In this way, the posture of the control lever 110 relative to the body 210 is adjustable, and the control lever 110 can be maintained in the adjusted posture, which helps to improve the ease of use of the operating device 100.

[0040] In some embodiments, such as Figure 2 and Figure 5As shown, the control lever 110 has a through hole 100a. The body 210 includes a first main body 211 and a second main body 212. The second main body 212 includes a shaft 2121 and a body 2122. The shaft 2121 passes through the through hole 100a of the operating member 140, and the opposite ends of the shaft 2121 are respectively connected to the first main body 211 and the body 2122. The control lever 110 is rotatably connected to the shaft 2121, thereby realizing the rotatable connection between the operating member and the body 210. When the operating member 140 is in the first operating position, the operating member can rotate around the shaft 2121 under the action of external force, so as to realize the adjustable attitude of the control lever 110 relative to the body 210.

[0041] For example, the shaft 2121 can be fastened to the first body 211 and the body 2122 by fasteners.

[0042] like Figure 2 As shown, for example, ratchet 120, pawl 130, transmission mechanism 160 and elastic element 150 can be located between the first body 211 and the second body 212. The first body 211 and the second body 212 can play a protective role. The operating element 140 passes through the mounting hole 211a of the first body 211 and is connected to the transmission mechanism 160 for transmission.

[0043] For example, the ratchet 120 can be integrally mounted on the control lever 110 or the machine body 210 by means of integral casting, integral injection molding, or integral welding, so that the ratchet 120 and the control lever 110 are not detachable. "The ratchet 120 and the control lever 110 are integral" means that the ratchet 120 and the control lever 110 are not detachable; that is, disassembling the ratchet 120 and the control lever 110 would cause structural damage to both the ratchet 120 and the control lever 110, and would make them irreparable.

[0044] For example, the pawl 130 is rotatably or slidably connected to the joystick 110 or the body 210.

[0045] For example, the elastic element 150 includes, but is not limited to, torsion springs, extension springs, and leaf springs.

[0046] For example, the elastic element 150 is a telescopic spring. One end of the elastic element 150 can be connected to either the control lever 210 or the body 210 connected to the pawl. The other end of the elastic element 150 can be connected to the pawl 130 via the transmission mechanism 160. Alternatively, the other end of the elastic element 150 can be directly connected to the pawl 130 so that the elastic element 150 acts elastically on the pawl and can provide elastic force to the pawl 130.

[0047] In some embodiments, the ratchet 120 has a hole 120a for accommodating the pawl 130, and the inner wall of the hole 120a is provided with a plurality of ratchet teeth 121. It is understood that the ratchet 120 is an internally engaged ratchet 120, with a plurality of ratchet teeth 121 on the inner wall of its hole 120a. The pawl 130 can be located within the hole 120a and can move within the hole 120a to switch between a state of engagement with the ratchet teeth 121 and a state of disengagement from the ratchet teeth 121, thereby improving space utilization.

[0048] For example, such as Figure 2 and Figure 4 As shown, the ratchet 120 is disposed within the through hole 100a of the control lever 110, and the shaft 2121 passes through the hole 120a of the ratchet 120. The first body 211 has a connecting portion 2111 passing through the hole 120a. The connecting portion 2111 is located between the shaft 2121 and the ratchet 120 and abuts against the outer peripheral surface of the shaft 2121 and the inner peripheral wall of the hole 120a. When the operating member 140 is in the first operating position, the operating member can drive the ratchet 120 to rotate around the connecting portion 2111 and the shaft 2121 under the action of external force. The pawl 130 is movably connected to the connecting portion 2111 so that the pawl 130 is movably connected to the body 210.

[0049] For example, the operating member 140 is rotatably or slidably connected to the machine body 210, and the operating member 140 can rotate or slide relative to the machine body 210 so that the operating member 140 can switch between a first operating position and a second operating position.

[0050] In some embodiments, the operating element 140 can remain in a first operating position under the action of an external force. For example, the user can continuously operate the operating element 140 so that the operating element 140 remains in the first operating position under the action of an external force, and then hold the joystick 110 and control the joystick 110 to rotate relative to the body, thereby adjusting the attitude of the joystick 110 relative to the body.

[0051] In some embodiments, the operating member 140 can be engaged with the body 210 to maintain it in a first operating position or a second operating position. For example, the operating member 140 is engaged with the body 210 so that the operating member 140 and the body 210 are maintained in the first operating position, and then the joystick 110 can be held and rotated relative to the body to adjust the attitude of the joystick 110 relative to the body.

[0052] like Figure 2 and Figure 3As shown, in some embodiments, the elastic element 150 is connected to the transmission mechanism 160, and the transmission mechanism 160 is driven to the pawl 130. When no external force is applied to the operating member 140, the elastic element 150 provides an elastic force to the first end 131 of the pawl 130 through the transmission mechanism 160 to engage with the ratchet 121. The pawl 130 and the transmission mechanism 160 can remain stationary relative to the body 210 under the action of the elastic force of the elastic element 150. At the same time, the transmission mechanism 160 is driven to the operating member 140 so that the operating member 140 can be kept in the second operating position under the limit of the transmission mechanism 160.

[0053] like Figure 2 and Figure 4 As shown, in some embodiments, the operating element 140 is rotatably connected to either the control lever 110 or the body 210 connected to the pawl 130. The operating element 140 is provided with an eccentric portion 143 or a cam portion. The transmission mechanism 160 is slidably connected to either the control lever 110 or the body 210 connected to the pawl 130. The eccentric portion 143 or the cam portion is drively connected to the transmission mechanism 160, and the eccentric portion 143 or the cam portion can drive the transmission mechanism 160 to slide. In this way, it is advantageous for the operating element 140 to drive the transmission mechanism 160 to slide significantly even when the user's operating range is small, quickly disengaging the pawl 130 from the ratchet 121, making it convenient for the user to operate the operating element 140.

[0054] Understandably, the eccentric part 143 is eccentrically positioned relative to the rotation center of the operating member 140. When the operating member 140 drives the eccentric part 143 to rotate, the eccentric part 143 abuts against the transmission mechanism 160. The transmission mechanism 160 slides under the thrust of the eccentric part 143, so that the transmission mechanism 160 drives the pawl 130 to move. When the operating member 140 drives the cam part to rotate, the cam part abuts against the transmission mechanism 160. The transmission mechanism 160 slides relative to the cam part along its curved trajectory. The transmission mechanism 160 slides under the thrust of the cam part, so that the transmission mechanism 160 drives the pawl 130 to move.

[0055] For example, the sliding direction of the transmission mechanism 160 is perpendicular to the rotation direction of the control member, and the sliding direction can be as follows: Figure 2 The Y0-Y1 direction is shown in the figure.

[0056] For example, such as Figure 2 and Figure 4As shown, the operating component 140 includes a handle 141 and a drive shaft 142. The drive shaft 142 includes a first shaft segment 1421 and a second shaft segment 1422 connected together. The outer diameter of the first shaft segment 1421 is larger than the outer diameter of the second shaft segment 1422. The end of the second shaft segment 1422 away from the first shaft segment 1421 passes through the mounting hole 211a of the first body 211 and is connected to the handle 141, so that the first body 211 is rotatably engaged between the handle 141 and the first shaft segment 1421, realizing the operable connection between the operating component 140 and the machine body 210. By holding the handle 141 and rotating it relative to the machine body 210, the operating component 140 can be switched between a first operating position and a second operating position.

[0057] Combination Figure 5 As shown, the transmission mechanism 160 further includes a first slide groove 160a. An eccentric portion 143 or a cam portion is located within the first slide groove 160a. When the eccentric portion 143 or the cam portion rotates, it abuts against the wall of the first slide groove 160a and can slide along the wall of the first slide groove 160a, thereby driving the transmission mechanism 160 to slide. It is understood that the eccentric portion 143 or the cam portion being located within the first slide groove 160a facilitates a stable transmission connection between the operating member 140 and the transmission mechanism 160. Simultaneously, it facilitates the operating member 140 driving the pawl 130 to separate from the ratchet 121 via the transmission mechanism 160, or facilitates the transmission mechanism 160 driving the operating member 140 to switch from a first operating position to a second operating position in preparation for subsequent operations.

[0058] For example, the eccentric portion 143 or the cam portion extends into the first groove 160a along the rotation direction of the control member.

[0059] For example, such as Figure 5 As shown, the first groove 160a is a strip groove, and the extension direction of the first groove 160a is perpendicular to the sliding direction of the transmission mechanism 160. When the operating member 140 rotates and drives the transmission mechanism 160 to slide through the eccentric part 143 or the cam part, the force transmitted from the operating member 140 to the transmission mechanism 160 is parallel to the sliding direction of the transmission mechanism 160, thereby improving the transmission efficiency.

[0060] In one exemplary embodiment, the operating member 140 is provided with an eccentric portion 143 located in the first slide groove 160a. When the operating member 140 switches from the second operating position to the first operating position, viewed from the Z0 side to the Z1 side, the operating member 140 can rotate clockwise around the axis in the Z0-Z1 direction under the action of an external force, so as to drive the transmission mechanism 160 to slide in the Y1 direction through the eccentric portion 143, so that the transmission mechanism 160 drives the pawl 130 to separate from the ratchet 120. After the operating member rotates relative to the body 210, viewed from the Z0 side to the Z1 side, the operating member 140 rotates clockwise around the axis in the Z0-Z1 direction. The component 140 can rotate counterclockwise around the axis in the Z0-Z1 direction under the action of external force, switching from the first operating position to the second operating position, and driving the transmission mechanism 160 to slide in the Y0 direction through the eccentric part 143, so that the transmission mechanism 160 drives the pawl 130 to engage with the ratchet 120 and then removes the external force applied to the operating component 140. The elastic element 150 is connected to the first end 131 of the pawl 130, or the elastic element 150 is connected to the transmission mechanism 160, so that the pawl 130 is kept engaged with the ratchet 120 under the action of the elastic force of the elastic element 150.

[0061] In another exemplary embodiment, the operating member 140 is provided with an eccentric portion 143 located within the first slide groove 160a. When the operating member 140 switches from the second operating position to the first operating position, viewed from the Z0 side to the Z1 side, the operating member 140 can rotate clockwise around the axis in the Z0-Z1 direction under the action of an external force. This allows the transmission mechanism 160 to slide along the Y1 direction via the eccentric portion 143, causing the transmission mechanism 160 to separate the pawl 130 from the ratchet 120. After the operating member rotates relative to the machine body 210, the external force applied to the operating member 140 is removed, and the transmission... The mechanism 160 is connected to the elastic element 150. The transmission mechanism 160 slides along the Y0 direction under the elastic force of the elastic element 150. The transmission mechanism 160 drives the pawl 130 to engage with the ratchet 120. The pawl 130 remains engaged with the ratchet 120 under the action of the elastic force. At the same time, the eccentric shaft of the operating element 140 abuts against the wall of the first slide groove 160a. Observed from the Z0 side to the Z1 side, the transmission mechanism 160 drives the operating element 140 to rotate counterclockwise around the axis in the Z0-Z1 direction, switching from the first operating position to the second operating position, preparing the operating element 140 for subsequent operations.

[0062] Of course, in other embodiments, the eccentric portion 143 or the cam portion may be located on the outer periphery of the transmission mechanism 160, and the eccentric portion 143 or the cam portion drives the transmission mechanism 160 to slide by abutting against the outer surface of the transmission mechanism 160.

[0063] In some embodiments, the transmission mechanism 160 is slidably connected to one of the control lever 110 and the body 210 connected to the pawl 130. The second end 132 of the pawl 130 is rotatably connected to the other of the control lever 110 and the body 210, while the first end 131 is drively connected to the transmission mechanism 160. It is understood that the transmission mechanism 160 slidably drives the pawl 130 to rotate relative to the control lever 110 or the body 210 so that the pawl 130 engages with the ratchet 121, saving space occupied by the transmission mechanism 160 and the pawl 130, and facilitating the installation of the pawl 130.

[0064] Furthermore, the first end 131 has a transmission part 1311, and the transmission mechanism 160 is provided with a second slide groove 160b. The transmission part 1311 is located within the second slide groove 160b. When the transmission mechanism 160 slides, the wall surface of the second slide groove 160b abuts against the transmission part 1311, thereby driving the transmission part 1311 to slide along the wall surface of the second slide groove 160b and rotate relative to the machine body 210. It can be understood that the transmission part 1311 is located within the second slide groove 160b to facilitate the transmission mechanism 160 driving the pawl 130 to engage with the ratchet 121.

[0065] As an example, as described above, after the control member rotates relative to the body 210, the control member 140 can switch from the first operating position to the second operating position under the action of external force, and drive the transmission mechanism 160 to slide along the Y0 direction, so that the transmission mechanism 160 drives the pawl 130 to rotate to engage with the ratchet 120 and then removes the external force applied to the control member 140. The elastic member 150 is connected to the first end 131 of the pawl 130, or the elastic member 150 is connected to the transmission mechanism 160, so that the pawl 130 remains engaged with the ratchet 120 under the action of the elastic force of the elastic member 150.

[0066] Another example, as described above, is that after the control member rotates relative to the body 210, the external force applied to the control member 140 is removed, the transmission mechanism 160 is connected to the elastic member 150, the transmission mechanism 160 slides along the Y0 direction under the elastic force of the elastic member 150, and the transmission mechanism 160 drives the pawl 130 to rotate until it engages with the ratchet 120.

[0067] For example, such as Figure 2 and Figure 4 As shown, the transmission mechanism 160 is located between the first body 211 and the ratchet 120. The transmission part 1311 of the pawl 130 can extend from inside the hole 120a of the ratchet 120 to outside the hole 120a and pass through the second slide groove 160b of the transmission mechanism 160. Specifically, the first body 211 is provided with a slide groove, and the transmission mechanism 160 is slidably engaged in the slide groove so that the transmission mechanism 160 can slide stably under the drive of the operating member 140.

[0068] For example, there may be one or more pawls 130.

[0069] like Figure 3 and Figure 5 As shown, in some embodiments, the transmission mechanism 160 is provided with at least two second slide grooves 160b, which are symmetrical about a first plane, the first plane being the plane containing the rotation axis of the ratchet 120. There are at least two pawls 130, which are symmetrical about the first plane, and the transmission parts 1311 of the two pawls 130 are respectively located within the two second slide grooves 160b. It can be understood that the symmetry of the two second slide grooves 160b and the symmetry of the two pawls 130 about the first plane allows the operating member 140 to slide when switched to the first operating position, and the transmission mechanism 160 simultaneously drives the two pawls 130 to rotate in opposite directions. The two pawls 130 can simultaneously disengage from the ratchet 121, simplifying the operation of the operating device 100.

[0070] For example, such as Figure 3 As shown, when no external force is applied to the operating member 140, the elastic member 150 is connected to the transmission mechanism 160. The elastic member 150 can drive the transmission mechanism 160 to slide, so that the transmission mechanism 160 drives the two pawls 130 to rotate in opposite directions. The two pawls 130 can simultaneously engage with the ratchet 121, stably limiting the rotation of the control lever 110.

[0071] Of course, in other embodiments, the operating member 140 may also drive multiple pawls 130 to move relative to the control lever 110 or the body 210 through multiple transmission mechanisms 160 respectively.

[0072] In some embodiments, the body 210 includes a first body 211 and a second body 212, with the first body 211 connected to the second body 212, and the joystick 110 located between the first body 211 and the second body 212. A damping element 170 is provided between the joystick 110 and the first body 211, and / or, a damping element 170 is provided between the joystick 110 and the second body 212. The damping element 170 is used to provide rotational damping force to the joystick 110, improving the feel of the joystick when operated by the user.

[0073] Optionally, the damping component 170 may include, but is not limited to, a disc spring, a rubber pad, or damping oil.

[0074] For example, such as Figure 2 As shown, the outer periphery of the shaft 2121 has a stepped surface. The disc spring can be sleeved on the outer periphery of the shaft 2121 and abut against the stepped surface of the shaft 2121 and the control lever 110. The disc spring is deformed by the compression of the shaft 2121 and the control lever 110, so that the disc spring can provide rotational damping force to the control lever 110.

[0075] Furthermore, the first body 211 is connected to the second body 212 via an adjusting member 180. The adjusting member 180 is used to adjust the clamping force of the first body 211 and / or the second body 212 on the damping member 170, thereby adjusting the rotational damping force provided by the damping member 170 to the control lever 110. By adjusting the rotational damping force provided by the damping member 170 to the control lever 110 through the adjusting member 180, the operating feel of the control lever 110 is adjustable, thereby meeting the usage needs of different users.

[0076] For example, the adjusting element 180 includes adjusting screws, adjusting bolts, etc.

[0077] For example, such as Figure 3 As shown, one end of the shaft 2121 is connected to the first body 211, and the other end is connected to the second body 212 via an adjusting screw. A butterfly spring is sleeved on the outer circumference of the shaft 2121 and abuts against the stepped surface of the shaft 2121 and the control lever 110. By tightening the adjusting screw, the clamping force of the shaft 2121 and the first body 211 on the damping element 170 increases, thereby increasing the compression of the butterfly spring, which in turn increases the rotational damping force provided by the butterfly spring to the control lever 110. As a result, the external force required to control the control lever 110 to rotate relative to the body 210 increases. By loosening the adjusting screw, the clamping force of the shaft 2121 and the first body 211 on the damping element 170 decreases, thereby decreasing the compression of the butterfly spring, which in turn decreases the rotational damping force provided by the butterfly spring to the control lever 110. As a result, the external force required to control the control lever 110 to rotate relative to the body 210 decreases. In this way, the control feel of the control lever 110 is adjustable.

[0078] like Figure 6 As shown, in a second aspect, embodiments of this application also provide a water propulsion device 200. It includes a fuselage 210 and an operating device 100 as described above.

[0079] For example, the fuselage 210 is provided with a power unit 220, which can be signal connected to the control lever 110 of the operating device 100. The control lever 110 is used to adjust the attitude of the power unit 220.

[0080] For example, the power unit 220 includes a drive unit and a propeller. The drive unit is located on the fuselage 210 and is driven by the propeller to rotate the propeller in the water to generate thrust. The drive unit can be an electric motor capable of driving the propeller to rotate. The drive unit can directly drive the propeller or drive the propeller via a transmission mechanism.

[0081] For example, the water propulsion device 200 can be an outboard motor, a trolley motor, a stern motor, or other equipment that can provide power in a body of water.

[0082] likeFigure 7 As shown, in a third aspect, embodiments of this application also provide a water-based mobile device 300. The water-based mobile device 300 includes the water-based thruster 200 described above.

[0083] For example, the water-mobile device 300 can be various water transportation vehicles such as commercial ships, passenger ships, yachts, fishing boats, sailboats, and civilian ships, or it can be water patrol equipment, water management equipment, water environment monitoring equipment, etc. that can move in water. This application does not specifically limit this.

[0084] For example, the water-based mobile device 300 includes a carrier 310 and a water-based thruster 200. The water-based thruster 200 is mounted on the carrier 310, and the propeller of the water-based thruster 200 rotates in the water to generate thrust, thereby driving the carrier 310 to move or turn.

[0085] For example, the water propulsion device 200 also includes a clamp connected to the fuselage 200, which is connected to the side plate of the carrier. The clamp is provided with a tilting shaft and a steering shaft. The fuselage 210 can tilt up and down relative to the carrier in the longitudinal section of the carrier around the tilting shaft, and the fuselage 210 can also rotate left and right in the horizontal section of the carrier around the steering shaft. When the control stick 110 is fixed to the fuselage 210, by applying a longitudinal and horizontal force to the end of the control stick 110 away from the fuselage 200, the fuselage 210 can be driven to rotate around the tilting shaft and the steering shaft, so as to adjust the angle between the propulsion force of the water propulsion device 200 and the horizontal plane, and to adjust the propulsion heading angle of the water propulsion device 200.

[0086] In this embodiment, a rotatable grip is provided at the end of the joystick 110 away from the body 210. The joystick 110 also has a sensor that can sense the amount of rotation of the grip, and a control circuit board electrically connected to the sensor. The control circuit board is electrically connected to a drive component. Based on the amount of grip rotation sensed by the sensor, the control circuit board outputs a control command to control the power of the drive component.

[0087] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The embodiments described above only illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
