[0002] Some known outboard motors feature a tilting mechanism that uses this mechanism to generate tilting power, allowing the propeller to lift out of the water and protect it from corrosion caused by prolonged immersion. However, when operating mobile equipment in water, the propeller's propulsion power generates vibrations that can be easily transmitted to the tilting mechanism, causing damage and failure, thereby shortening the outboard motor's service life. Summary of the Invention

[0003] The present application provides a lifting fixture, a propeller and a movable device in water areas, which can prevent vibration from being transmitted to the lifting structure and extend the service life of the outboard motor.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, the present application provides a lifting fixture for connecting a propeller to a water body. The lifting fixture comprises a fixed bracket, a lifting bracket, a connecting assembly, and a vibration damping structure. One side of the fixed bracket is used to connect to the water body. The lifting bracket is rotatably connected to the other side of the fixed bracket. The connecting assembly is used to connect to the main unit of the propeller. The vibration damping structure is disposed between the lifting bracket and the connecting assembly and is used to absorb vibrations of the main unit.

[0006] The lifting clamp of the present application has a vibration-damping structure connected between the lifting bracket and the connecting component. The vibration-damping structure can significantly reduce the vibration transmitted from the connecting component to the lifting bracket, thereby significantly reducing the vibration of the lifting bracket and the fixed bracket, ensuring the rotation safety of the lifting bracket relative to the fixed bracket, and extending the service life.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" as used herein includes any and all combinations of one or more of the relevant listed items.

[0102] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0103] Example 1

[0104] See also Figure 1 This embodiment provides a mobile device 300 for use in water areas, comprising a water carrier 301 and a propeller 200. The propeller 200 is connected to the water carrier 301 and is used to propel the mobile device 300. In this embodiment, the propeller 200 is mounted at the rear of the water carrier 301. In other embodiments, the connection position of the propeller and the water carrier 301 may be adjusted accordingly, depending on the specific requirements of the propeller's installation position on the water carrier 301.

[0105] The mobile device 300 in this embodiment can be any water vehicle, such as a passenger ship, yacht, fishing boat, or sailboat. This embodiment uses the water vehicle 301 as a ship hull and the propeller 200 as an outboard motor as an example. Of course, the mobile device 300 can also be an amphibious vehicle, an unmanned patrol boat, a water drone, or the like, without limitation.

[0106] See also Figure 2 The propeller 200 of this embodiment includes a main engine 201 and a tilting fixture 10. The tilting fixture 10 includes a fixed bracket 11, a tilting bracket 12, a connecting assembly 13 and a vibration reduction structure 14. The fixed bracket 11 is connected to the water body 301. The tilting bracket 12 is rotatably connected to the fixed bracket 11. The tilting bracket 12 and the fixed bracket 11 are connected by a rotating shaft 65 (see Figure 5 and Figure 11 ) are rotatably connected, and the rotation axis 18 of the two is the axis direction of the rotation axis 65. The rotation axis 65 can be fixed to one of the tilting bracket 12 and the fixed bracket 11, and the other of the tilting bracket 12 and the fixed bracket 11 rotates in conjunction with the rotation axis 65. The rotation axis 18 of the tilting bracket 12 relative to the fixed bracket 11 is parallel to the midline plane of the water body carrier 301. The connecting component 13 is connected to the tilting bracket 12 and is used to connect to the host 201. The vibration reduction structure 14 is provided between the tilting bracket 12 and the connecting component 13, and the vibration reduction structure 14 is used to absorb vibrations of the host 201.

[0107] In this embodiment, see Figure 1 The main machine 201 includes a frame 211, a steering actuator 204, and a power unit 208. The frame 211 is connected to the connecting assembly 13. The steering actuator 204 is mounted on the frame 211 and cooperates with the connecting assembly 13 to drive the frame 211 to rotate relative to the lifting fixture 10. The power unit 208 is mounted on the frame 211 and is used to output propulsion power.

[0108] In this embodiment, see Figure 2 and Figure 3The connecting assembly 13 includes a steering shaft 51, which is rotatably connected to the frame 211. The steering shaft 51 is connected to the water body 301 via the tilting bracket 12 and the fixed bracket 11, so that the steering shaft 51 can tilt relative to the water body 301. The steering shaft 51 is provided with a first steering tooth portion 52. The steering actuator 204 includes a steering motor, which is fixed to the frame 211. The output end of the steering motor is provided with a second steering tooth portion 205. The second steering tooth portion 205 engages with the first steering tooth portion 52, so that the steering torque output by the steering motor forces the steering motor and the frame 211 to rotate relative to the tilting fixture 10 around the axial direction of the steering shaft 51, and changes the orientation of the power part 208 connected to the frame 211, so that the direction of the propulsion power output by the power part 208 changes, thereby driving the water body 301 to turn. In other embodiments, the first steering tooth portion 52 and the second steering tooth portion 205 can also be matched through a reduction structure. In this embodiment, the output shaft of the steering actuator 204 is rotatably engaged with the driving bearing 207 on the frame 211 to improve the reliability of the steering actuator 204 in outputting the steering torque.

[0109] It is understood that in other embodiments, the steering force driven by the steering actuator 204 to the frame 211 can be replaced by a tiller that receives the driver's manual turning force, thereby driving the frame 211 to steer. In other embodiments, the steering actuator 204 configured as a steering motor can be replaced with a steering actuator 204 configured as an electro-hydraulic cylinder. In other embodiments, the steering actuator 204 can be mounted on the tilting bracket 12, and the steering shaft 51 can be fixed to the frame 211. The steering actuator 204 drives the steering shaft 51 to rotate relative to the tilting bracket 12, thereby driving the frame 211 to rotate.

[0110] In this embodiment, see Figure 1 The power part 208 includes a propulsion motor 209 and a propeller 210. The propulsion motor 209 is connected to the propeller 210 through a transmission mechanism to drive the propeller 210 to rotate and generate propulsion. Specifically, the propulsion motor 209 is fixed to the frame 211, and the propeller 210 is connected to the underwater part 203 of the frame 211 by a rotating shaft. The propulsion motor 209 can output the rotational torque to the propeller 210 directly through the rotating shaft, or it can output the rotational torque to the propeller 210 through a transmission mechanism and a reduction assembly. In this embodiment, see Figure 1 and Figure 2The tilting fixture 10 also includes a tilting drive member 64, which is connected between the fixed bracket 11 and the tilting bracket 12 and is used to drive the tilting bracket 12 to rotate relative to the fixed bracket 11. The tilting bracket 12 includes a rotating section 57 and a connecting section 58. The rotating section 57 is rotatably connected to the fixed bracket 11. The connecting section 58 is bent and connected to the rotating section 57 to form a "7"-shaped tilting bracket 12. The length direction of the connecting section 58 is perpendicular to the rotation axis 18 of the rotating section 57. The connecting assembly 13 is connected to the connecting section 58 via a vibration damping structure 14.

[0111] One end of the tilting drive member 64 is rotatably connected to the fixed bracket 11, and the other end is rotatably connected to the tilting bracket 12. The rotation axis of the tilting drive member 64 is parallel and spaced from the rotation axis of the tilting bracket 12 relative to the fixed bracket 11. The tilting drive member 64 is retractable to drive the frame 211 to tilt relative to the water body 301. The fixed bracket 11 can be fixedly connected to the water body 301 by welding, bolting, or locking clamps. The tilting drive member 64 can be a hydraulic cylinder, an electro-hydraulic cylinder, or other device capable of outputting power. For example, when the lifting drive component 64 is an electro-hydraulic push rod, one end thereof is connected to the fixed bracket 11 and is provided with a motor, a hydraulic cylinder and an oil storage chamber, and the other end is a telescopic end. The motor at the telescopic end controls the oil in the oil storage chamber to enter the hydraulic cylinder to adjust the hydraulic size of the hydraulic cylinder, thereby utilizing the hydraulic pressure to drive the telescopic end to extend and retract relative to the fixed bracket 11, and then the telescopic end is connected to the lifting bracket 12. The telescopic end can push the lifting bracket 12 to rotate relative to the fixed bracket 11, that is, to push the frame 211 to lift and rotate relative to the water carrier 301, thereby driving the connecting component 13, the steering shaft 51, the steering actuator 204 and the power part 208 to rotate and lift together.

[0112] It is understandable that the power part 208 outputs propulsion power, and the power part 208 is prone to vibration due to the interaction with the water area, that is, the power part 208 forms the vibration source of the propeller 200. Since the frame 211 is rigidly connected to the power part 208, the vibration of the power part 208 will be transmitted to the frame 211, and the frame 211 is rigidly matched in the axial direction of the steering shaft 51, which causes the steering shaft 51 to easily vibrate in the axial direction, and then the steering shaft 51 is at risk of transmitting the vibration to the lifting bracket 12. In order to avoid the vibration of the power part 208 from being transmitted to the lifting clamp 10, and also to prevent it from being transmitted to the water area carrier 301 through the lifting clamp 10, to avoid damage to the lifting clamp 10, and to avoid the vibration on the water area carrier 301 affecting the driving experience, a vibration reduction structure 14 is set between the connecting component 13 and the lifting bracket 12. The vibration reduction structure 14 is used to absorb vibration, thereby eliminating the vibration on the lifting clamp 10 and the water area carrier 301, ensuring the safety of the lifting clamp 10, and improving the driving experience. In the lifting fixture 10 of this embodiment, a vibration-damping structure 14 is connected between the lifting bracket 12 and the connecting assembly 13. This structure significantly reduces vibration transmitted from the connecting assembly 13 to the lifting bracket 12, thereby significantly reducing the amount of vibration between the lifting bracket 12 and the fixed bracket 11. This structure protects the connection between the lifting bracket 12 and the fixed bracket 11, and the connection between the fixed bracket 11 and the water body 301, ensuring the safe rotation of the lifting bracket 12 relative to the fixed bracket 11. It also eliminates vibration of the lifting drive element 64, ensuring safety, thereby ensuring the safety of the entire lifting fixture 10 and extending the service life of the propeller 200. Furthermore, since the amount of vibration received and transmitted by the fixed bracket 11 to the water body 301 is significantly reduced, the vibration of the water body 301 during operation of the water movable device 300 is also reduced, improving the riding experience for the driver and passengers. Furthermore, due to the improved vibration resistance of the lifting fixture 10, a more powerful power unit 208 can be selected, expanding the selection range of the main unit 201.

[0113] In this embodiment, see Figures 2 to 4 The connecting assembly 13 is provided with a connecting rod 15, which has a first end 16 and a second end 17 distributed along its length direction, and the length direction is perpendicular to the rotation axis 18 of the tilting bracket 12, and the first end 16 and the second end 17 are respectively used to connect the main unit 201 to the above-water part 202 away from the underwater and the underwater part 203 close to the underwater.

[0114] Specifically, see Figure 3The first end portion 16 is fixedly connected to the steering shaft 51. The frame 211 is provided with a steering bearing 54. The steering shaft 51 is assembled in the steering bearing 54. A seal 55 is provided on the side of the steering bearing 54 close to the second end portion 17. The seal 55 is sleeved on the steering shaft 51 and abuts against the end face of the steering bearing 54. The seal 55 prevents water from entering from the joint between the frame 211 and the steering shaft 51, thereby ensuring the safety of the electronic components inside the frame 211. Specifically, the first end portion 16 is provided with a socket along the axial direction, and the steering shaft 51 is inserted into the socket. The portion of the steering shaft 51 inserted into the socket is provided with a rotation-stopping structure, which cooperates with the inner wall of the socket to limit the rotation of the steering shaft 51 relative to the first end portion 16. Of course, in other embodiments, a socket can also be provided at the end of the steering shaft 51.

[0115] In this embodiment, see Figure 3 The side of the steering shaft 51 is provided with a steering protrusion 53 housed in a steering bearing 54. The steering protrusion 53 is disposed opposite the first steering tooth portion 52. The steering bearing 54 is a thrust bearing, thereby transmitting the load of the main engine 201 to the steering shaft 51, thereby providing axial support for the main engine 201.

[0116] The main unit 201 also has a steering shaft hole 206 near the underwater portion 203. The second end portion 17 fits within the steering shaft hole 206. The tilting fixture 10 also includes a support bushing 56 that is sleeved over the second end portion 17 and fits within the steering shaft hole 206. The support bushing 56 is used to support the connecting rod 15. The second end portion 17 can be rotatably fitted within the support bushing 56 via its outer circumferential surface. The support bushing 56 provides radial support for the connecting rod 15 during the tilting process of the tilting bracket 12, thereby providing stable support.

[0117] In this embodiment, see Figure 5The vibration damping structure 14 includes a first vibration damper 19 and a second vibration damper 20. The first end 16 is connected to the portion of the connecting section 58 of the tilting bracket 12 near the rotating section 57 via the first vibration damper 19, and the second end 17 is connected to the portion of the connecting section 58 of the tilting bracket 12 away from the rotating section 57 via the second vibration damper 20. The first vibration damper 19 is connected to one end of the connecting rod 15 and the end of the connecting section 58 near the rotating section 57, while the second vibration damper 20 is connected to the other end of the connecting rod 15 and the end of the connecting section 58 away from the rotating section 57. This allows the first vibration damper 19 to absorb vibration at the connection between the one end of the connecting rod 15 and the end of the connecting section 58 near the rotating section 57, while the second vibration damper 20 to absorb vibration at the connection between the other end of the connecting rod 15 and the end of the connecting section 58 away from the rotating section 57, thereby improving the vibration damping effect. At the same time, during the process of the lifting bracket 12 lifting relative to the fixed bracket 11, the connecting rod 15 is provided with two spaced connection points in the direction perpendicular to the rotation axis 18 of the lifting bracket 12, and the two connection points are connected to the lifting bracket 12, one of the connection points is formed by the first end 16, the first vibration damper 19 and one end of the connecting section 58, and the other connection point is formed by the second end 17, the second vibration damper 20 and the other end of the connecting section 58. When the lifting bracket 12 is lifted relative to the fixed bracket 11, the lifting bracket 12 drives the connecting component 13 and the host 201 connected to the connecting component 13 to lift. The connecting component 13 mainly bears the weight of the host 201 through the connection between the first vibration damper 19 and the lifting bracket 12. The connection between the connecting component 13 and the lifting bracket 12 through the second vibration damper 20 forms a fulcrum to balance the torque at both ends of the connecting component 13. In this way, the first vibration damper 19 bears the force and the second vibration damper 20 forms a fulcrum to balance the gravity of the host 201 and drive the host 201 to lift, thereby better overcoming the weight of the host 201, making the lifting action of the host 201 more stable, and reducing the amount of vibration along the gravity direction generated during the lifting process of the host 201.

[0118] In this embodiment, see Figure 5 and Figure 6 The first vibration damper 19 is a columnar vibration damper, and the geometric center axis of the first vibration damper 19 is parallel to the rotation axis 18 of the tilting bracket 12. The first vibration damper 19 is used to absorb the vibration of the propeller 200 in its radial direction. The second vibration damper 20 is a columnar vibration damper, and the geometric center axis of the second vibration damper 20 is parallel to the rotation axis 18 of the tilting bracket 12. The second vibration damper 20 is used to absorb the vibration of the propeller 200 in its radial direction.

[0119] In this embodiment, the cross-section of the columnar vibration damper can be circular, rectangular, polygonal, or other special shapes. The columnar vibration damper can be made of rubber, meaning that both the first vibration damper 19 and the second vibration damper 20 are rubber-mounted. In other embodiments, both the first vibration damper 19 and the second vibration damper 20 can be hydraulically mounted.

[0120] In this embodiment, both the first vibration damper 19 and the second vibration damper 20 can absorb radial vibrations of the propeller 200. They can also absorb vibrations generated by the power unit 208. The vibrations generated by the gravity of the main engine 201 during the tilting process, as well as the currents or waves of the water body, also exert forces in the direction of gravity on the main engine 201. Furthermore, they can absorb a certain amount of vibration generated when the steering actuator 204 outputs a steering torque. In other embodiments, the geometric center axes of the first vibration damper 19 and the second vibration damper 20 can also be perpendicular to the rotation axis 18 of the tilting bracket 12 (i.e., the axis of the steering shaft 51), thereby improving the ability of the first vibration damper 19 and the second vibration damper 20 to absorb vibrations generated when the steering actuator 204 outputs a steering torque.

[0121] In this embodiment, see Figure 6 The connecting assembly 13 is provided with a first pull rod 21 and a second pull rod 22. The first pull rod 21 is provided at the first end 16, and the second pull rod 22 is provided at the second end 17. The tilting bracket 12 is provided with a first mating hole 23 and a second mating hole 24 spaced apart. The first vibration damper 19 has an axial hole along its axis. The first pull rod 21 passes through the axial hole and tightly fits with the inner wall of the axial hole. The first vibration damper 19 is assembled in the first mating hole 23 and tightly fits with the inner wall of the first mating hole 23. The second vibration damper 20 has an axial hole along its axis. The second pull rod 22 passes through the axial hole and tightly fits with the inner wall of the axial hole. The second vibration damper 20 is assembled in the second mating hole 24 and tightly fits with the inner wall of the second mating hole 24. The first and second pull rods 21 and 22 are respectively fixedly connected to the first and second vibration dampers 19 and 20, so that the inner side of the first vibration damper 19 abuts against the connecting assembly 13, the outer side of the first vibration damper 19 abuts against the tilting bracket 12, the inner side of the second vibration damper 20 abuts against the connecting assembly 13, and the outer side of the second vibration damper 20 abuts against the tilting bracket 12, thereby enabling the first and second vibration dampers 19 and 20 to absorb vibration. In other embodiments, the first and second pull rods 21 and 22 may also be provided on the tilting bracket 12, the connecting assembly 13 defines corresponding first and second mating holes 23 and 24, the first vibration damper 19 fits between the outer wall of the first pull rod 21 and the inner wall of the first mating hole 23, and the second vibration damper 20 fits between the outer wall of the second pull rod 22 and the inner wall of the second mating hole 24, thereby similarly achieving the vibration absorption function of the first and second vibration dampers 19 and 20.

[0122] In this embodiment, see Figure 6 The tilting bracket 12 is provided with a first groove 33. First mating holes 23 are provided on opposite side walls of the first groove 33. One end of the first pull rod 21 engages with one of the first mating holes 23, and the other end engages with the other first mating hole 23. In this embodiment, the first groove 33 is formed by a recessed portion of the side of the tilting bracket 12 facing the main body 201 and is disposed at the junction of the rotating section 57 and the connecting section 58. If the tilting bracket 12 does not have the first groove 33, there will be no overlapping portion between the tilting bracket 12 and the connecting rod 15, which means that the overall stacking volume of the tilting bracket 12 and the connecting rod 15 increases. In this embodiment, the provision of the first groove 33 allows the first vibration damper 19 to be accommodated within the first groove 33. The connecting rod 15 partially overlaps the tilting bracket 12, reducing the stacking volume of the connecting rod 15 and the tilting bracket 12. This utilizes the internal space of the tilting bracket 12, thereby effectively reducing the size of the tilting fixture 10 in the propulsion direction 69 and increasing the applicability of the tilting fixture 10. In addition, since the top surface of the rotating section 57 away from the fixed bracket 11 is concave to form a part of the first groove 33, the diameter of the first groove 33 in the rotating section 57 is larger than the diameter in the connecting section 58, which increases the assembly working space of the first vibration damper 19 and the first pull rod in the first groove 33, thereby facilitating the installation of the first vibration damper 19 and the first pull rod 21 in the first matching hole 23, improving the disassembly and assembly efficiency of the lifting clamp 10, and facilitating the maintenance and replacement of the first vibration damper 19.

[0123] In this embodiment, see Figure 6 The connecting assembly 13 also includes a first connecting block 34 connected to the sidewall of the first end portion 16. The first pull rod 21 is provided with two locking rods 35. The two locking rods 35 are located on either side of the first connecting block 34 along the rotation axis 18 of the tilting bracket 12 and respectively engage with the two first mating holes 23. The outer surface of the first vibration damper 19 tightly engages with the first mating holes 23, and the outer surface of the locking rods 35 tightly engages with the axial hole of the first vibration damper 19. The first connecting block 34 has a connecting hole away from the first end portion 16. The locking rods 35 pass through the first vibration damper 19 within the first mating hole 23 and extend into the connecting hole, where they are threadedly connected to the first connecting block 34 to lock the first vibration damper 19 between the locking rods 35 and the first mating holes 23. The locking rods 35 simultaneously lock the first vibration damper 19 and connect the first connecting block 34 to the tilting bracket 12. In other embodiments, the locking rod 35 may be used only to install the first vibration damper 19, and other locking structures may be used to lock the first vibration damper 19. In other embodiments, the first pull rod 21 may also be configured as a separate rod, with both ends of the rod respectively engaged in the first engagement hole 23.

[0124] In this embodiment, see Figure 6 and Figure 7First sealing covers 25 are provided at the openings of the first mating holes 23 on opposite sides of the tilting bracket 12. The first pull rod 21 and the first vibration damper 19 are located between the two first sealing covers 25. The first sealing covers 25 can seal the openings on both sides of the tilting bracket 12, significantly reducing the possibility of water entering the first mating holes 23. This protects the first pull rod 21 and the first vibration damper 19, reducing the possibility of damage or shortening the life of the first vibration damper 19 due to water, thereby extending the service life of the first vibration damper 19 and ensuring its vibration absorption function.

[0125] In this embodiment, see Figure 7 The first sealing cover 25 is provided with a first sealing block 27 that extends into the first mating hole 23. A first external thread 28 is provided on the side of the first sealing block 27. A first internal thread 29 is provided in the first mating hole 23. The first external thread 28 and the first internal thread 29 are threadedly engaged to securely connect the first sealing cover 25 to the tilting bracket 12. In other embodiments, the first sealing cover 25 can also be interference-fitted into the first mating hole 23, or secured to the tilting bracket 12 by screws to seal the openings on both sides of the tilting bracket 12.

[0126] In this embodiment, see Figure 6 The connecting assembly 13 is provided with a stopper 36, which protrudes from the first connecting block 34. The stopper 36 fits within the first groove 33 and is supported on the bottom surface of the first groove 33 to support the first connecting block 34 and the first pull rod 21. After the connecting assembly 13 is connected to the host 201, it will be pressed against the tilting bracket 12 under the action of the gravity of the host 201. The stopper 36 can provide reliable support for the connecting assembly 13 and the host 201, and can also buffer the collision between the first connecting block 34 and the tilting bracket 12 during the tilting process of the tilting bracket 12.

[0127] In this embodiment, see Figure 6 and Figure 8The tilting bracket 12 is provided with a second groove 37, and the opposite side walls of the second groove 37 are provided with second matching holes 24. The second pull rod 22 passes through a second matching hole 24, a second groove 37 and another second matching hole 24 in sequence along its rotation axis 18 to match the two second matching holes 24 and the second groove 37. The second groove 37 is formed by the connecting section 58 being concave on the side facing the main body 201. The connecting assembly 13 also includes a second connecting block 38, which is connected to the connecting rod 15 and is matched in the second groove 37 to connect with the second pull rod 22. A through hole is provided at the end of the second connecting block 38 away from the connecting rod 15. The second pull rod 22 passes through the through hole and is tightly matched with the inner wall of the through hole. In other embodiments, the second pull rod 22 can also be threadedly connected to the second connecting block 38. If the tilting bracket 12 does not have a second groove 37, a raised portion for mounting the second pull rod 22 is required on the surface of the tilting bracket 12. This will increase the size of the tilting fixture 10 with the second vibration damper 20 along the propulsion direction 69. By providing the second groove 37, the second vibration damper 20 can be accommodated within the second groove 37, utilizing the internal space of the tilting bracket 12 to reduce the size of the tilting fixture 10 in the propulsion direction 69 and increase the applicability of the tilting fixture 10. Furthermore, during assembly, the second connecting block 38 can be first placed into the second groove 37, and then the second pull rod 22 can be inserted into the second mating hole 24 and passed through the through hole of the second connecting block 38, thereby facilitating the assembly of the second pull rod 22 and the second connecting block 38. In other embodiments, the second groove 37 can also be formed by a concave portion at the junction of the side of the connecting section 58 facing the main unit 201 and the bottom surface of the connecting section 58 parallel to the rotating section 57 (i.e., the surface facing downward in the direction of gravity).

[0128] In this embodiment, see Figure 8 Second sealing covers 26 are provided at the openings of the two second mating holes 24 on opposite sides of the tilting bracket 12. The second tie rod 22 and the two second vibration dampers 20 are located between the two second sealing covers 26. The second sealing covers 26 seal the openings on both sides of the tilting bracket 12, significantly reducing the possibility of water entering the second mating holes 24. This protects the second tie rod 22 and the second vibration dampers 20, reducing the possibility of damage or shortening the life of the second vibration dampers 20 due to water, thereby extending the service life of the second vibration dampers 20 and ensuring their vibration absorption function.

[0129] In this embodiment, see Figure 8The second sealing cover 26 is provided with a second sealing block 30 that extends into the second mating hole 24. A second external thread 31 is provided on the side of the second sealing block 30. A second internal thread 32 is provided in the second mating hole 24. The second external thread 31 and the second internal thread 32 are threadedly engaged to securely connect the second sealing cover 26 to the tilting bracket 12. In other embodiments, the second sealing cover 26 can also be interference-fitted into the second mating hole 24, or secured to the tilting bracket 12 via screws to seal the openings on both sides of the tilting bracket 12.

[0130] In this embodiment, see Figure 8 The end of the second tie rod 22 is provided with a locking member 39, which is used to lock the second tie rod 22 to the tilting bracket 12 to fix the second vibration damper 20 to the tilting bracket 12. One end of the second tie rod 22 passes through the second connecting block 38 from one second mating hole 24 and extends into the other second mating hole 24. Ultimately, the two ends of the second tie rod 22 are respectively located in the two second mating holes 24 and simultaneously engage with the two second vibration dampers 20. The locking member 39 is connected to the second tie rod 22 from one end and locked between one second vibration damper 20 and the first sealing cover 25 or the second sealing cover 26, thereby securing the second tie rod 22. In this embodiment, the locking member 39 can be threadedly connected to the second tie rod 22, can be interference fit with the second tie rod 22, or can be fixedly connected to the second tie rod 22 by other connection methods such as pins and screws.

[0131] In other embodiments, two locking members 39 are provided, and the two locking members 39 are respectively fixedly connected to the second pull rod 22 and abut against the opposite ends of the two second vibration dampers 20 to fix the two second vibration dampers 20 on the second pull rod 22.

[0132] In this embodiment, see Figure 6 A side of the connecting section 58 of the lifting bracket 12 facing the main machine 201 is provided with an avoidance groove 66. The length direction of the avoidance groove 66 is perpendicular to the rotation axis 18 of the lifting bracket 12. Part of the connecting rod 15 is fitted into the avoidance groove 66 to reduce the size of the lifting clamp 10 in the propulsion direction 69 of the propeller 200, thereby improving the applicability of the lifting clamp 10.

[0133] In this embodiment, see Figures 6 to 8Two first vibration dampers 19 are provided, with the first end 16 connected to the tilting bracket 12 via two first vibration dampers 19 on either side. Two second vibration dampers 20 are provided, with the second end 17 connected to the tilting bracket 12 via two second vibration dampers 20 on either side. Specifically, the two first vibration dampers 19 are spaced apart along the rotation axis 18 of the tilting bracket 12, and the two second vibration dampers 20 are spaced apart along the rotation axis 18 of the tilting bracket 12. This increases the vibration-damping contact area between the ends of the connecting rod 15 and the tilting bracket 12, improving the vibration absorption effect of the vibration-damping structure 14. Furthermore, the first end 16 is connected to the tilting bracket 12 via two fulcrums, and the second end 17 is connected to the tilting bracket 12 via two fulcrums. This improves the stability of the connection between the connecting rod 15 and the tilting bracket 12, allowing the tilting bracket 12 to stably and reliably drive the main unit 201 connected to the connecting rod 15 to tilt during tilting, ensuring the reliability and safety of the tilting operation.

[0134] Example 2

[0135] Figure 9 Another lifting jig 10 is shown, which is different from the aforementioned lifting jig 10 in that the specific structure of the vibration reduction structure 14 of the lifting jig 10 is different.

[0136] In this embodiment, the second vibration damper 20 is a cylindrical damper, with its geometric center axis perpendicular to the rotation axis 18 of the tilting bracket 12. The second vibration damper 20 is used to absorb radial vibrations of the propeller 200. Two first vibration dampers 19 are provided. Both of these first vibration dampers 19 are cylindrical dampers, with their geometric center axes perpendicular to the rotation axis 18 of the tilting bracket 12. The first vibration dampers 19 are used to absorb radial vibrations of the propeller 200. The second vibration damper 20 can absorb steering-direction vibrations generated by the steering actuator 204 when it outputs steering torque, steering-direction vibrations imposed on the main engine 201 by waves, and vibrations in the propulsion direction 69 generated by the power unit 208. The first vibration damper 19 can absorb vibrations generated by the power unit 208 along the propulsion direction 69, as well as vibrations caused by the main engine 201's gravity during the tilting process. Thus, the first vibration damper 19 and the second vibration damper 20 cooperate to absorb the vibration in the X, Y, and Z directions of the three-dimensional coordinate system, thereby improving the comprehensiveness of vibration damping.

[0137] In this embodiment, two first vibration dampers 19 are provided, spaced apart along the rotational axis 18 of the tilting bracket 12. A single second vibration damper 20 is provided. During the tilting process of the tilting fixture 10, the moment arms at the first end 16 and underwater portion 203 on either side of the second end 17 are relatively large. The first vibration dampers 19 experience greater lateral tension, while the second vibration dampers 20 experience relatively less thrust. The second vibration damper 20 forms the intermediate fulcrum of the moment-balancing moment arm. This results in relatively less force on the second vibration damper 20, allowing only one second vibration damper 20 at the second end 17 to meet vibration absorption requirements and balance torque during the tilting process. In other embodiments, three or more first vibration dampers 19 may also be provided. In this embodiment, the first vibration dampers 19 are provided on either side of the connecting rod 15 along the rotational axis 18 of the tilting bracket 12, while the second vibration damper 20 is sleeved onto the connecting rod 15. In this way, the two first vibration dampers 19 and the second vibration dampers 20 are symmetrically distributed about the connecting rod 15, so that the fulcrum formed by the second vibration damper 20 can provide relatively balanced support for the force arms at the two first vibration dampers 19. In other embodiments, the distribution of the two first vibration dampers 19 and the second vibration damper 20 can also be adjusted according to actual needs.

[0138] In this embodiment, the tilting bracket 12 is provided with a rotation hole 50, the length of which is perpendicular to the rotation axis 18 of the tilting bracket 12. The connecting rod 15 fits within the rotation hole 50, and the second vibration damper 20 fits between the second end 17 of the connecting rod 15 and the rotation hole 50. Specifically, the second vibration damper 20 defines an axial hole along its axis, and the second end 17 penetrates into the axial hole and tightly fits with the inner wall of the axial hole. The second vibration damper 20 is assembled within the rotation hole 50 and tightly fits with the inner wall of the rotation hole 50. The rotation hole 50 serves as a position limit for the connecting rod 15 and also facilitates the installation of the second vibration damper 20, whose geometric center axis is perpendicular to the rotation axis 18 of the tilting bracket 12, between the connecting rod 15 and the tilting bracket 12. In other embodiments, instead of providing the rotation hole 50 on the tilting bracket 12, a boss can be provided on the end of the connecting section 58 facing away from the rotation section 57, and a connecting structure can be provided at the second end 17. The connecting structure engages with the boss, and the second vibration damper 20 engages between the boss and the connecting structure to facilitate installation of the second vibration damper 20. The connection between the second vibration damper 20, the boss, and the connecting structure can be referenced to the connection between the second vibration damper 20, the second mating hole 24, and the second pull rod 22 in the first embodiment, and will not be further described here. Therefore, there are many ways to install the second vibration damper 20 with the tilting bracket 12 and the connecting rod 15, which are not specifically limited here.

[0139] In this embodiment, the connecting assembly 13 further includes a third connecting block 40 and a third pull rod 41. The third connecting block 40 is protruded from the first end 16 along the propulsion direction 69. The third pull rod 41 is provided on the third connecting block 40. The tilting bracket 12 is provided with a third mating hole 42. The first vibration damper 19 is fitted between the third mating hole 42 and the third pull rod 41. Specifically, the first vibration damper 19 has an axial hole along its axis. The third pull rod 41 passes through the axial hole and tightly fits with the inner wall of the axial hole. The first vibration damper 19 is assembled in the third mating hole 42 and tightly fits with the inner wall of the third mating hole 42. In this embodiment, the third pull rod 41 can be threadedly connected to the third connecting block 40 or locked to the third connecting block 40 by a locking structure. In other embodiments, the third connecting block 40 can be provided on the tilting bracket 12, and the third mating hole 42 can be provided on the connecting assembly 13. In this embodiment, a cover may be provided at the opening of the third matching hole 42 to seal the opening of the third matching hole 42 and protect the third pull rod 41 and the first vibration damper 19 .

[0140] In this embodiment, the tilting bracket 12 is provided with a third groove 43. Third mating holes 42 are provided on opposite sides of the third groove 43. The ends of the third pull rod 41 respectively engage with the two third mating holes 42. The two first vibration dampers 19 respectively engage between the two third mating holes 42 and the two third pull rods 41. In this embodiment, the third groove 43 is formed by an inward depression on the side of the tilting bracket 12 facing the main unit 201 and is located at the junction of the rotating section 57 and the connecting section 58.

[0141] Example 3

[0142] Figures 10 to 12 Another lifting jig 10 is shown, which is different from the lifting jig 10 of the second embodiment in that the specific structure of the first vibration damping member 19 of the lifting jig 10 is different.

[0143] See also Figure 10 and Figure 11In this embodiment, the second vibration damper 20 is a cylindrical damper, with its geometric center axis perpendicular to the rotation axis 18 of the tilting bracket 12. The second vibration damper 20 is used to absorb radial vibration of the propeller 200. The two first vibration dampers 19 are cylindrical dampers, with their geometric center axes perpendicular to the rotation axis 18 of the tilting bracket 12. The first vibration dampers 19 are used to absorb radial vibration of the propeller 200. In this embodiment, both the first and second vibration dampers 19 and 20 can absorb steering-direction vibration generated by the steering actuator 204 outputting steering torque, steering-direction vibration imposed on the main engine 201 by waves, and propulsion-direction vibration 69 generated by the power section 208. Furthermore, when the tilting bracket 12 drives the connecting assembly 13 to rotate, the first and second vibration dampers 19 and 20 can also absorb vibration caused by gravity during the tilting of the main engine 201. In this embodiment, the steering shaft 51 is connected to the first end portion 16 , and a first steering gear portion 52 is provided on a side of the steering shaft 51 away from the first end portion 16 .

[0144] In this embodiment, see Figure 10 and Figure 11 The connecting assembly 13 further includes an adapter block 44, one end of which is connected to the first end portion 16, and the other end of the adapter block 44 is provided with two mounting holes 70. The tilting bracket 12 is provided with two mounting posts 45, which are spaced apart along the rotation axis 18 of the tilting bracket 12. The two mounting posts 45 are respectively fitted into the two mounting holes 70, and the first vibration damper 19 is fitted between the mounting holes 70 and the mounting posts 45. Specifically, the first vibration damper 19 has an axial hole along its axis, and the mounting posts 45 pass through the axial hole and tightly fit with the inner wall of the axial hole. The first vibration damper 19 is assembled into the mounting hole 70 and tightly fits with the inner wall of the mounting hole 70. In other embodiments, the mounting hole 70 can also be provided on the tilting bracket 12, and the mounting posts 45 can be provided at the end of the adapter block 44, so that the first vibration damper 19 can be installed between the tilting bracket 12 and the connecting assembly 13.

[0145] In this embodiment, see Figure 11 and Figure 12 The lifting fixture 10 also includes a fixing screw 47 and a fixing gasket 48. The fixing gasket 48 cooperates with the first vibration damper 19 and rests against the mounting column 45. The fixing screw 47 is threadedly connected to the mounting column 45 and locks the fixing gasket 48 to the mounting column 45 to fix the first vibration damper 19 to the mounting column 45, thereby achieving fixed installation of the first vibration damper 19 between the lifting bracket 12 and the adapter block 44.

[0146] In this embodiment, the lifting bracket 12 is provided with a mounting groove 46, two mounting posts 45 protruding from the bottom surface of the mounting groove 46, and the adapter block 44 is mounted within the mounting groove 46. The mounting groove 46 helps reduce the size of the lifting bracket 12 in the direction of gravity, thereby reducing the size of the lifting fixture 10 in the direction of gravity and increasing the applicability of the lifting fixture 10. In this embodiment, a buffer pad 49 is also provided between the adapter block 44 and the bottom surface of the mounting groove 46. The buffer pad 49 provides reliable support for the connecting assembly 13 and the main unit 201, and also provides a buffering and support function for collisions between the adapter block 44 and the lifting bracket 12 during the lifting process of the lifting bracket 12.

[0147] In this embodiment, see Figure 11 The lower end of the tilting bracket 12 is provided with a connecting portion 68, and the rotation hole 50 is provided in the connecting portion 68. The side of the tilting bracket 12 is also provided with an avoidance groove 66, which is connected to the rotation hole 50. In other embodiments, the tilting bracket 12 can also be provided with a complete rotation hole 50 for accommodating the first end 16 and the second end 17 of the connecting rod 15.

[0148] Example 4

[0149] Figure 13 Another lifting jig 10 is shown, which is different from the lifting jig 10 of the previous embodiment in that the specific structures of the first vibration damping member 19 and the second vibration damping member 20 of the lifting jig 10 are different.

[0150] In this embodiment, the first vibration damper 19 is a cylindrical damper with its geometric center axis perpendicular to the rotation axis 18 of the tilting bracket 12. The first vibration damper 19 is used to absorb vibration of the propeller 200 in its radial direction. The second vibration damper 20 is a cylindrical damper with its geometric center axis parallel to the rotation axis 18 of the tilting bracket 12. The second vibration damper 20 is used to absorb vibration of the propeller 200 in its radial direction. The first vibration damper 19 can absorb the steering vibration generated by the steering actuator 204 when it outputs steering torque, the steering vibration exerted on the main engine 201 by waves, and the vibration in the propulsion direction 69 generated by the power section 208. The second vibration damper 20 can absorb the vibration generated by the power section 208 along the propulsion direction 69 and the vibration caused by the weight of the main engine 201 during the tilting process. Thus, the first vibration damper 19 and the second vibration damper 20 work together to absorb vibration in the X, Y, and Z directions of the three-dimensional coordinate system, improving comprehensive vibration reduction.

[0151] In this embodiment, two first vibration dampers 19 are provided, and one second vibration damper 20 is provided.

Specifically, the first vibration damper 19 has an axial hole along its axis, the mounting rod 59 is inserted into the axial hole and tightly fits with the inner wall of the axial hole, the first vibration damper 19 is assembled into the straight hole 61 and tightly fits with the inner wall of the straight hole 61. In this embodiment, the first vibration damper 19 can be locked to the mounting rod 59 by screws. The connection structure between the first vibration damper 19, the tilting bracket 12 and the connecting assembly 13 can refer to the connection structure between the first vibration damper 19, the tilting bracket 12 and the connecting assembly 13 in Example 3, and will not be repeated here.

[0153] In this embodiment, see Figure 13 The connecting assembly 13 further includes a fourth tie rod 62, which is disposed at the second end 17. The tilting bracket 12 defines a fourth mating hole 63, in which the fourth tie rod 62 fits, and the second vibration damper 20 fits between the fourth tie rod 62 and the fourth mating hole 63. Specifically, the second vibration damper 20 defines an axial hole along its axis, the fourth tie rod 62 passes through the axial hole and tightly fits with the inner wall of the axial hole, and the second vibration damper 20 is assembled in the fourth mating hole 63 and tightly fits with the inner wall of the fourth mating hole 63. At the same time, the tilting fixture 10 further includes a tie rod connecting block 67, which is disposed at the second end 17 and connected to the fourth tie rod 62. In this embodiment, the specific connection structure of the second vibration damper 20, the tilting bracket 12, and the connecting assembly 13 can refer to the connection structure of the second vibration damper 20, the tilting bracket 12, and the connecting assembly 13 in the first embodiment, and will not be repeated here.
