Description

Technical Field

[0001] This application relates to the field of waterborne mobile equipment, and more specifically, to lifting devices, waterborne propulsion devices, and waterborne mobile equipment. Background Technology

[0002] Water-based mobile equipment, such as yachts, may require tilting and lowering their outboard motors as needed.

[0003] In related technologies, the tilting structure of outboard motors can use support pins to support and limit the outboard motor at a limited position. However, this limiting structure is prone to failure. Summary of the Invention

[0004] This application provides a lifting device, a water propulsion device, and a water-mobile device.

[0005] In a first aspect, this application provides a lifting device for lifting a water propeller, the lifting device comprising:

[0006] Fixed base, defining the support position and mating groove;

[0007] A rotating bracket is rotatably connected to the fixed base;

[0008] The limiting bracket has a first end and a second end opposite to each other; the first end is rotatably connected to the rotating bracket, and the second end is provided with a support pin and a mating pin; the support pin and the mating pin are respectively axially aligned with the fixed seat, and the mating pin is axially telescopically provided in the limiting bracket;

[0009] In the limited position, the support pin is supported at the support position, and the mating pin extends into the mating groove to restrict the second end of the limiting bracket from sliding relative to the fixed seat.

[0010] In the lifting device of this application, when the support pin is in the support position, the weight of the main body of the water propeller is released to the support pin, and the fixing seat supports the support pin, so that the main body can be fixed in the high lifting position. At this time, the mating pin is not under force, which can avoid the problem of the mating pin deforming under force and being unable to extend or retract, thus preventing the automatic guidance from failing. This helps to reduce the risk of limit failure. Furthermore, in the limit position, the limit of the mating pin in the mating groove can prevent the support pin from leaving the support position, thereby reducing the risk of the water propeller leaving the limit position due to the bumps of the water mobile device or other reasons.

[0011] Secondly, this application provides a water propulsion device, including a main body and the aforementioned lifting device; the main body is connected to the rotating support.

[0012] Thirdly, this application provides a water-based mobile device, including a water-based carrier and the aforementioned water-based propulsion device, wherein the mounting base is connected to the water-based carrier. Attached Figure Description

[0082] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0083] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0084] Example

[0085] See Figure 1 and Figure 2 This embodiment provides a water-based mobile device 300, including a water-based carrier 310 and a water-based thruster 100. The water-based thruster 100 is connected to the water-based carrier 310 and is used to propel the water-based mobile device 300.

[0086] In this embodiment, the water-based mobile device 300 can be various vessels such as passenger ships and yachts, the corresponding water-based carrier 310 is the hull, and the water-based propulsion device 100 is the outboard motor. Of course, the water-based mobile device 300 can also be a fishing boat, sailboat, or other vessels, and is not limited here.

[0087] The water propulsion device 100 includes a main body 110 and a lifting device 10. The main body 110 includes a propulsion motor 111 and a propeller 112. The propulsion motor 111 is connected to the propeller 112 and drives the propeller 112 to rotate, generating propulsion force. The lifting device 10 connects the main body 110 to the water carrier 310.

[0088] During normal operation, the water propulsion unit is in the lowered position, meaning the propeller 112 is below the water level L1 to provide propulsion, as described in [reference needed]. Figure 2 When necessary, such as when the boat is stopped, the water thruster can be tilted to the limit position, so that the water thruster 100 tilts above the water level line L1, as seen in... Figure 1 .

[0089] See Figure 3 The lifting device 10 includes a fixed base 11, a rotating bracket 12, and a limiting bracket 13. The fixed base 11 is used for fixed connection to the water carrier 310 (see...). Figure 1 or Figure 2 For example, it is fixed to the tail of the water carrier 310; the rotating bracket 12 is rotatably connected to the fixed base 11 and is used to fix the connecting body 110 (see Figure 1 or Figure 2 The limiting bracket 13 can be supported between the rotating bracket 12 and the fixed base 11 to enable the rotating bracket 12 and the main body 110 to be supported in the limiting position.

[0090] In this embodiment, the lifting device 10 further includes a lifting driver 14; the lifting driver 14 is connected to the rotating bracket 12 and is used to drive the rotating bracket 12 to rotate relative to the fixed base 11. The lifting driver 14 can be a linear motor, cylinder, or other linear driver. Optionally, one end of the lifting driver 14 is rotatably connected to the fixed base 11, and the other end is rotatably connected to the rotating bracket 12, with the rotation axis parallel and spaced apart from the rotation axis of the rotating bracket 12 relative to the fixed base 11, so as to drive the rotating bracket 12 to rotate and lift.

[0091] In this embodiment, the rotating support 12 includes a horizontal extension 15 and a vertical extension 16, which are connected to form an L-shape. The end of the horizontal extension 15 away from the vertical extension 16 is hinged to the fixed base 11, and the vertical extension 16 is used to connect to the main body 110 of the water propulsion device 100.

[0092] In other embodiments, the rotating bracket 12 may also be configured in other shapes as needed.

[0093] See Figure 4 In this embodiment, the fixed base 11 defines the support position 17 and the mating groove 18. The limiting bracket 13 has a first end 19 and a second end 20 opposite to each other. The first end 19 is rotatably connected to the rotating bracket 12, and the second end 20 is provided with a support pin 52 and a mating pin 53. The support pin 52 and the mating pin 53 correspond to the fixed base 11 along their respective axial directions, and the mating pin 53 is axially telescopingly disposed in the limiting bracket 13.

[0094] At the limit position (e.g.) Figure 4 (position), support pin 52 is supported at support position 17, and mating pin 53 extends into mating groove 18 to restrict the second end 20 of limit bracket 13 from sliding relative to fixed seat 11.

[0095] In the relevant technology, the support pin is used as both a water propeller supporting the raised position and a limiting function. The applicant found that the structure is prone to deformation due to the load on the support pin, which affects its guiding effect and reduces its limiting function. There may be a risk of the limiting pin coming loose, which could affect the safety of the water-based mobile equipment.

[0096] In this embodiment, when the support pin 52 is in the support position 17, the weight of the main body 110 of the water propeller 100 is released to the support pin 52, and the fixing seat 11 supports the support pin 52, so that the main body 110 can be fixed in the high-point tilted position. At this time, the mating pin 53 is not under force, which can avoid the problem that the mating pin 53 will deform under force and cannot extend or retract, thus preventing the automatic guidance from being achieved. This helps to reduce the risk of limit failure. Furthermore, in the tilted position, since the mating pin 53 and the support pin 52 are both set on the limit bracket 13, the limit of the mating pin 53 in the mating groove 18 can limit the further rotation of the limit bracket 13 as a whole, thereby preventing the support pin 52 from leaving the support position 17, thereby reducing the risk of the water propeller 100 leaving the tilted position due to the bumps of the water mobile device 300 or other reasons.

[0097] See also Figure 4 In this embodiment, the fixed base 11 includes a first base plate 21 and a second base plate 22 spaced apart from each other. A rotating bracket 12 is rotatably connected between the first base plate 21 and the second base plate 22. The second end 20 of the limiting bracket 13 is located between the first base plate 21 and the second base plate 22. In this embodiment, the outer contours of the first base plate 21 and the second base plate 22 can be set to be substantially the same.

[0098] The first seat plate 21 has a first surface 23, and the second seat plate 22 has a second surface 24, with the first surface 23 and the second surface 24 spaced apart from each other.

[0099] See also Figure 5 and Figure 6 In this embodiment, the first base plate 21 and the second base plate 22 of the fixed base 11 are respectively provided with support positions 17 to facilitate the support of the limiting bracket 13 from both sides and improve the support reliability. The first base plate 21 is provided with a mating groove 18 for engaging with the mating pin 53 of the limiting bracket 13. In other embodiments, the second base plate 22 may also be provided with a mating groove 18.

[0100] The first base plate 21 has a groove 25 formed by recessing from the first surface 23, and the support position 17 and the mating groove 18 are located in the groove 25.

[0101] The groove 25 has a bottom surface 26 and a peripheral surface 27. The peripheral surface 27 includes a lower surface 28, an upper surface 29, a first side surface 30, and a second side surface 31. The lower surface 28 and the upper surface 29 are vertically aligned, and the first side surface 30 and the second side surface 31 are laterally opposite and connected between the upper surface 29 and the lower surface 28, respectively. The support position 17 is located on the first side surface 30. When the groove is raised, the rotating bracket 12 rotates relative to the fixed seat 11, and drives the support pin 52 of the limiting bracket 13 to slide along the first side surface 30 towards the upper surface 29 to the support position 17 in a state of elastic pressure against the first side surface 30. Optionally, a torsion spring 54 is connected between the rotating bracket 12 and the limiting bracket 13. The elastic force applied by the torsion spring 54 to the limiting bracket 13 causes the support pin 52 of the limiting bracket 13 to tend to move towards the first side surface 30, so that the second end 20 of the limiting bracket 13 can move relative to the fixed seat 11 along a defined trajectory.

[0102] In this embodiment, see reference. Figure 7 and Figure 5 A guide platform 32 protrudes from a portion of the bottom surface 26 of the groove. The platform 33 of the guide platform 32 includes a connected guide surface 34 and a top surface 35. The guide surface 34 is an inclined surface, and the recessed depth of the guide surface 34 near the top surface 35 is less than the recessed depth of the side away from the top surface 35. The mating groove 18 is formed recessed from the top surface 35. The mating pin 53 can move to the platform 33 that mates with the guide platform 32, and during the lifting process, the mating pin 53 is guided by the guide surface 34 to slide to the top surface 35 and elastically extends into the mating groove 18. Optionally, the mating groove 18 is U-shaped with an upward opening.

[0103] The upper surface 29 is inclined, with the side closer to the first side 30 being lower and the side closer to the second side 31 being higher; the opening of the mating groove 18 corresponds to the lower side of the upper surface 29 of the groove peripheral surface 27; the area of ​​the groove bottom surface 26 near the higher side of the upper surface 29 is recessed relative to the bottom surface of the mating groove 18 to form a release groove 36, and a fall-back step surface 37 is formed between the mating groove 18 and the release groove 36; during the release process, the rotating bracket 12 rotates relative to the fixed seat 11 so that the mating pin 53 moves out from the mating groove 18 to the lower side of the upper surface 29, and moves along the upper surface 29 to its higher side until it crosses the fall-back step surface 37 to the position corresponding to the release groove 36, and the mating pin 53 can elastically extend into the release groove 36.

[0104] A partition wall 38 is provided between the guide platform 32 and the release groove 36, extending outward along the depth direction of the fixed seat 11. The surface of the partition wall 38 near the release groove 36 is a fall-back guide surface 39, which is connected to the lower part of the fall-back step surface 37 (i.e., the side of the fall-back step surface 37 away from the upper surface 29). The fall-back guide surface 39 is used to guide the mating pin 53 to slide downward relative to the fixed seat 11, and the fall-back guide surface 39 is configured to guide the mating pin 53 to move a set distance away from the first side surface 30 (this set distance is related to the extension length of the fall-back guide surface 39), so that during the release process, the support pin 52 is laterally offset from the support position 17.

[0105] The partition wall 38 includes an inclined wall 40 and a vertical extension wall 41 connected below the inclined wall 40. The lower end of the inclined wall 40 is closer to the second side 31 than the upper end. The vertical extension wall 41 and the support position 17 are laterally offset. When the mating pin 53 is located at the lower end of the vertical extension wall 41, the support pin 52 is located below the support position 17. In this way, the support pin 52 can be prevented from accidentally entering the support position 17 and being blocked during the release of the limit.

[0106] In this embodiment, the first side surface 30 includes a first surface segment 42, a second surface segment 43, and a third surface segment 44. The third surface segment 44 is concave relative to the first surface segment 42 and extends away from the second side surface 31. The second surface segment 43 connects the first surface segment 42 and the third surface segment 44 and is U-shaped with an upward opening, forming a support position 17 for engaging the support pin 52. During the process of the support pin 52 moving along the first surface segment 42 to enter the support position 17, the engaging pin 53 and the first side surface 30 remain spaced apart from each other, and the engaging pin 53 is not obstructed by the first side surface 30.

[0107] In this embodiment, optionally, the groove 25 includes a first groove area 45 and a second groove area 46. The depth of the first groove area 45 is greater than the depth of the second groove area 46. The support position 17 is disposed in the first groove area 45, and the mating groove 18 is disposed in the second groove area 46. The insertion depth of the support pin 52 is less than the depth of the first groove area 45 but greater than the depth of the second groove area 46. The insertion depth of the support pin 52 is less than the depth of the first groove area 45, so that the end face of the support pin 52 and the fixing seat 11 are kept at a distance from each other. In this way, the end face of the support pin 52 will not contact the bottom surface of the first groove area 45 and rub against each other during relative movement. At the same time, during the movement, the support pin 52 will not enter the second groove area 46 due to the step formed by the depth difference between the first groove area 45 and the second groove area 46, thus avoiding interference with the protruding structure of the second groove area 46. In addition, the first groove 45 with a larger recessed depth allows the support pin 52 to obtain a larger axial support length (i.e., the axial length of the contact section between the support pin 52 and the first seat plate 21 / second seat plate 22), improving support reliability and reducing the deformation of the support pin 52.

[0108] See you again Figure 6 In this embodiment, the outer contour of the second base plate 22 can be substantially similar to that of the first base plate 21. The second base plate 22 is provided with a support position 17 for supporting one end of the limiting bracket 13. The second base plate 22 can be provided with an inwardly recessed groove, similar to the first base plate 21, and a support position 17 for supporting the limiting bracket 13 is provided on the side of the groove. Of course, the groove on the second base plate 22 should also avoid the movement trajectory of the support pin 52 to ensure that the movement of the support pin 52 is not obstructed.

[0109] It should be noted that, Figures 5-7 The first seat plate 21 and the second seat plate 22 shown are merely examples. In other embodiments, the first seat plate 21 and the second seat plate 22 may be provided in other forms, as long as they can form a support pin 52 for supporting the limiting bracket 13 and a mating pin 53 for limiting the limiting bracket 13.

[0110] See Figure 8 In this embodiment, the limiting bracket 13 also includes a main frame 47, an elastic element 48, a mating pin 53 and two support pins 52.

[0111] The main frame 47 includes a horizontal plate portion 49 and vertical plate portions 50 connected to both sides of the horizontal plate portion 49. The horizontal plate portion 49 is provided with a cylindrical portion 51 for rotatably connecting to the rotating bracket 12. Two support pins 52 are respectively connected to the side of the two vertical plate portions 50 away from the horizontal plate portion 49, and extend outward from the vertical plate portions 50 in a mutually distancing direction, for respectively engaging with the support positions 17 on the first base plate 21 and the second base plate 22.

[0112] A mating pin 53 is provided on the longitudinal plate portion 50 facing the first seat plate 21. In this embodiment, the mating pin 53 is slidably connected to the main frame 47, and an elastic element 48 (e.g., a compression spring) is elastically supported between the main frame 47 and the mating pin 53 to apply an elastic force toward the first seat plate 21 of the fixed seat 11 to the mating pin 53. Thus, when the mating pin 53 is not subjected to axial force, it will extend under the action of the elastic element 48; when subjected to the axial pressure of the first seat plate 21, the elastic element 48 is compressed and the mating pin 53 retracts.

[0113] In this embodiment, optionally, both the mating pin 53 and the support pin 52 are cylindrical, and the diameter of the mating pin 53 is smaller than that of the support pin 52. The circular shape of the support pin 52 / matting pin 53 facilitates relative sliding under the guidance of the groove side of the groove 25, and makes it less prone to slippage and jamming.

[0114] In this embodiment, optionally, the mating pin 53 is located on the side of the support pin 52 near the first end 19 of the limiting bracket 13, that is, the mating pin 53 is located between the support pin 52 and the cylindrical portion 51. Correspondingly, the mating groove 18 is located on the support position 17 closer to the rotating bracket 12 (see...). Figure 4( ) on one side of the rotation center.

[0115] The following describes the lifting and lowering process of the water-based mobile device 300 in the embodiments of this application.

[0116] Figure 7 , Figure 9 , Figure 10 The diagram shows the three states that the water-based mobile device 300 goes through in sequence during its lifting process.

[0117] like Figure 7 As shown, the water-based mobile device 300 is in the lowered position (see...). Figure 2 At this point, the support pin 52 and the mating pin 53 are located in the lower position shown in the diagram, and the torsion spring 54 (see...) Figure 4 Under the action of ), and with the large diameter of the support pin 52, the support pin 52 is pressed to the left against the first side 30 of the groove 25 of the first seat plate 21.

[0118] A lifting operation is applied to the water-accessible mobile device 300, and the support pin 52 slides upward along the first surface segment 42 of the first side 30 until it crosses the first surface segment 42 and enters the second surface segment 43 to engage with the support position 17. Figure 9 The diagram shows the state when the support pin 52 is located at the junction of the first face segment 42 and the second face segment 43. Figure 10 This shows the state when the support pin 52 is engaged with the support position 17, at which point the water-mobile device 300 is in the limited position (see [reference]). Figure 1 ).

[0119] During this process, the mating pin 53 moves synchronously with the supporting pin 52. As the mating pin 53 moves, it is guided by the inclined guide surface 34 into the top surface 35, and continues to move from the top surface 35 to the corresponding mating groove 18. Upon reaching the corresponding mating groove 18, the mating pin 53 extends under the elastic force of the elastic element 48 and is inserted into the mating groove 18 (see...). Figure 10 When the mating pin 53 is in the mating groove 18, the support pin 52 is exactly supported at the support position 17, so that the limit of the mating pin 53 in the mating groove 18 can prevent the support pin 52 from disengaging from the support position 17, thereby ensuring that the water propulsion device 100 is reliably kept in the limit position.

[0120] Figures 10-13 The diagram shows several states that the water-based mobile device 300 passes through in sequence during its deployment.

[0121] exist Figure 10 The indicated limit position allows for the lowering of the water propeller 100. The rotating bracket 12 can be manually or electrically driven to continue rotating, causing the support pin 52 to move upwards away from the support position 17 and the mating pin 53 to move upwards away from the mating groove 18. (See [reference needed]). Figure 11 ;

[0122] Continue rotating the rotating bracket 12. Guided by the inclined section of the upper surface 29 of the first seat plate 21, the engaging pin 53 shifts away from the first side 30, causing the support pin 52 to be laterally offset from the first side 30 and the support position 17 thereon, as seen in... Figure 12 ;exist Figure 12 In this state, the mating pin 53 extends elastically into the release groove 36. Due to the fall-off step surface 37 between the release groove 36 and the mating groove 18, the mating pin 53 that has entered the release groove 36 cannot retract into the mating groove 18, ensuring that the lowering process proceeds in the positive direction.

[0123] exist Figure 12 In this state, the water propeller 100 can be released, causing it to fall automatically. The cooperating pin 53 moves downwards under the guidance of the return step surface 37 and the return guide surface 39, as seen in... Figure 13 The partition wall 38 is designed to prevent the mating pin 53 from shifting laterally during the lowering process, thus keeping the support pin 52 laterally offset from the support position 17. The lower section of the partition wall 38 extends a certain length until the mating pin 53 moves to the lower end of the partition wall 38, at which point the support pin 52 has already descended to a position below the support position 17.

[0124] As the cooperating pin 53 continues to descend, disengaging from the support of the partition wall 38, the limiting bracket 13 rotates to the left under the elastic force of the torsion spring 54 until the supporting pin 52 elastically engages with the first surface section 42 again and moves downward along the first surface section 42. Figure 7 The lowering position shown indicates the completion of the lowering action of the water propulsion unit 100.

[0125] In this embodiment, the axial telescopic guiding and limiting functions are achieved by the mating pin 53, while the support pin 52 does not need to perform this function. Thus, during use, even if the support pin 52 is bent and deformed due to mainly bearing the weight of the water propeller 100, its sliding guidance relative to the fixed seat 11 can still smoothly enter and reliably remain in the support position 17 under the guidance of the mating pin 53. The water propeller 100 is easy to lift and the support is safe and stable.

[0126] Furthermore, through the aforementioned sliding path setting and anti-reverse setting, it can be ensured that the lifting and lowering process proceeds smoothly in the forward direction without any backflow; the support pin 52 will not be obstructed by the support position 17 during the downward movement process, thus affecting the lowering process of the water propeller 100, which means that the water propeller 100 can be lifted and lowered smoothly.

Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
