[0040] In some embodiments, the avoidance groove 32 can penetrate through the propulsion device fixing plate 3, and the avoidance groove 32 can be a closed hole structure for avoiding the lifting rod 210 in a vertical or substantially vertical direction to allow the lifting rod 210 to be lifted or lowered and to allow the lifting rod 210 to be rotated around its axis. In some further embodiments, the avoidance groove 32 can be an open groove structure with openings formed at the edges of the propulsion device fixing plate 3 for avoiding the lower structure of the lifting rod 210 when the lifting rod 210 is flipped from a vertical direction to a horizontal direction to allow the propeller 230 to be above or obliquely above the propulsion device fixing plate 3.

[0041] Figure 3 is a schematic view of a bracket according to further embodiments of the present description, Figure 4 is a schematic view of another side of a bracket according to further embodiments of the present description. See Figure 3 、 Figure 4 According to one or more embodiments of the present description, the bracket can further comprise one or more second bracket fixing plates 2 for fixing to the object to be fixed, and the second bracket fixing plate 2 is fixedly connected to the propulsion device fixing plate 3.

[0042] In some embodiments, the propulsion device fixing plate 3, due to its use in fixing the propulsion device, bears a large load, and the second bracket fixing plate 2 can enhance the strength of the propulsion device fixing plate 3. In some embodiments, the second bracket fixing plate 2 provides additional fixing points between the bracket and the hull to distribute the force exerted by the bracket on the hull.

[0043] In some embodiments, the second bracket fixing plate 2 may be parallel to the first bracket fixing plate 1. In other embodiments, the second bracket fixing plate 2 and the first bracket fixing plate 1 may have an included angle.

[0044] In some embodiments, the second bracket fixing plate 2 has a second fixing surface 20 that conforms to the object being fixed. In some embodiments, the shape of the second fixing surface 20 may match the shape of the hull side plate, the outer edge of the deck, and the bulkhead plate, or the overall shape of a plurality of such components, so as to fit closely to one or more of these structures.

[0046] In one or more embodiments of this specification, the mounting area 31 is disposed close to a first bracket fixing plate 1, and there is an accommodating space 33 between the mounting area 31 and another first bracket fixing plate 1.

[0047] For example, Figure 1 In the illustrated embodiment, the mounting area 31 is disposed near the first bracket fixing plate 1 on the left side, and an accommodating space 33 is provided between the mounting area 31 and the first bracket fixing plate 1 near the right side. For example, Figure 3 In the illustrated embodiment, the mounting area 31 is disposed near the front of the first bracket fixing plate 1, and an accommodating space 33 is provided between the mounting area 31 and the first bracket fixing plate 1 near the rear. For example, Figure 5 In the illustrated embodiment, the mounting area 31 is disposed near the first bracket fixing plate 1 on the right side, and an accommodating space 33 is provided between the mounting area 31 and the first bracket fixing plate 1 near the left side. For example, Figure 7 In the embodiment shown, the mounting area 31 is provided near the front of the first bracket fixing plate 1, and there is an accommodating space 33 between the mounting area 31 and the first bracket fixing plate 1 near the rear.

[0048] In some embodiments, the shape of the space containing the accommodating space 33 can be set according to actual needs. For example, the shape of the space containing the accommodating space 33 can be a rectangle, trapezoid, parallelogram, triangle, etc.

[0049] In some embodiments, the accommodation space 33 is used to avoid and / or carry related structures when the lifting rod 210 is flipped or in the flipped state, for example, to avoid the lifting driving mechanism 250. In some further embodiments, the propulsion device fixing plate 3 can also support the lifting driving mechanism 250 at the accommodation space 33.

[0050] In one or more embodiments of the present specification, referring to Figures 1 to 8 As shown, the first support fixing plate 1 comprises a first part 11 fixedly connected with the propulsion device fixing plate 3 and a second part 12 extending downward from one end of the first part 11. In some embodiments, the second part 12 is fixedly connected with the side surface of the fixed object.

[0051] In some embodiments, the first support fixing plate 1 is an integral structure. In some embodiments, the first part 11 can extend in a substantially horizontal direction, and the second part 12 can extend along the surface profile of the fixed object. In some embodiments, the first part 11 and the second part 12 can have an included angle therebetween.

[0052] In some embodiments, referring to Figures 1 to 8 As shown, the first support fixing plate 1 further comprises a third part 13 extending upward from one end of the first part 11. In some embodiments, the second part 12 and the third part 13 can be located at the lower side and the upper side of the first part 11, respectively, to increase the contact area between the support and the fixed object and to realize the connecting space.

[0053] In some embodiments, the width of the first part 11 in the substantially vertical direction at the end close to the second part 12 and / or the third part 13 is greater than the width of the first part 11 in the substantially vertical direction at the end away from the second part 12 and / or the third part 13, to increase the structural strength of the first support fixing plate 1. In some embodiments, the thickness of the first part 11 in the substantially horizontal direction at the end close to the second part 12 and / or the third part 13 can also be greater than the thickness of the first part 11 in the substantially horizontal direction at the end away from the second part 12 and / or the third part 13.

[0054] In some embodiments, referring to Figure 3 and Figure 4 , Figure 7 and Figure 8 As shown, the third part 13 can be fixedly connected with the side surface of the fixed object. For example, the third part 13 can be fixedly connected with the side plate of the ship body.

[0055] In some embodiments, referring to Figure 1 and Figure 2 , Figure 5 and Figure 6As shown, the third portion 13 can be fixedly connected with the side surface and the upper surface of the object to be fixed.

[0056] In some embodiments, the third portion 13 can include a transverse portion 131 extending in a transverse direction (e.g. horizontal direction or substantially horizontal direction). In some embodiments, the transverse portion 131 clamps the side of the hull with the second portion 12 to provide a good fixing effect.

[0057] In some embodiments, the first bracket fixing plate 1 can be in the "y" shape as shown in FIG. 1B, or in the "Y" shape as shown in FIG. 1C. Figure 3 、 Figure 7 In some embodiments, the first bracket fixing plate 1 can be in the "y" shape as shown in FIG. 1B, or in the "Y" shape as shown in FIG. 1C. Figure 1 、 Figure 5 In some embodiments, the first bracket fixing plate 1 can be in the "y" shape as shown in FIG. 1B, or in the "Y" shape as shown in FIG. 1C.

[0058] In one or more embodiments of the present specification, there is a gap between the propulsion device fixing plate 3 and the object to be fixed to avoid the propulsion device fixing plate 3 from being knocked against the hull due to vibration or deformation.

[0059] In one or more embodiments of the present specification, the spatial shape of the first fixing surface 10 matches the spatial shape of the object to be fixed. In some embodiments, the object to be fixed has a bracket mounting area, and the spatial shape of the first fixing surface 10 is determined by the scanning data of the spatial shape of the bracket mounting area of the object to be fixed.

[0060] In some embodiments, the bracket mounting area can be a spatial cambered surface. In some embodiments, the bracket mounting area has a convexity or concavity in the length direction of the hull, and the included angle between the two first bracket mounting plates is adjusted according to the convexity or concavity of the bracket mounting area in the length direction of the hull. In some embodiments, the bracket mounting area has a convexity or concavity in the height direction of the hull, and the first fixing surface 10 is correspondingly formed with a convexity or concavity according to the lines in the height direction of the hull to fit the hull.

[0061] In some embodiments, the spatial shape of the second bracket fixing surface 20 of the second bracket fixing plate 2 matches the spatial shape of the object to be fixed. In some embodiments, the spatial shape of the second fixing surface 20 is also determined by the scanning data of the spatial shape of the bracket mounting area of the object to be fixed.

[0062] In some embodiments, the spatial shape of the bracket mounting area of ​​the fixed object (e.g., a ship hull) is scanned to obtain a model of the spatial shape. The shape of the first fixing surface 10 of the first bracket fixing plate 1 is established based on the model. The overall shape of the first bracket fixing plate 1 is further designed and formed, and the first bracket fixing plate 1 is manufactured accordingly. In some embodiments, the shape of the second fixing surface 20 of the second bracket fixing plate 2 is established based on the model. The overall shape of the second bracket fixing plate 2 is further designed and formed, and the second bracket fixing plate 2 is manufactured accordingly.

[0063] In one or more embodiments of this specification, one or more weight-reducing holes are provided on the first support fixing plate 1 and / or the propulsion device fixing plate 3. For example, see [link to example]. Figure 3 , Figure 7 As shown, the first support fixing plate 1 has a first support fixing plate weight reduction hole 19, and the propulsion device fixing plate 3 has a propulsion device fixing plate weight reduction hole 39. In some embodiments, the weight reduction hole can be a round hole or a semi-circular hole. In other embodiments, the weight reduction hole can be of any shape.

[0064] In one or more embodiments of this specification, see Figures 1 to 8 As shown, the propulsion device fixing plate 3 is pentagonal, and includes a first side 41 facing the object being fixed, a second side 42 and a third side 43 adjacent to the first side 41, and a fourth side 44 and a fifth side 45 opposite to the first side 41. In some embodiments, the pentagonal propulsion device fixing plate 3 may have a portion protruding from the first support fixing plate 1, thereby allowing the propulsion device (e.g., a marine propulsion device 200) to protrude from the first support fixing plate 1 and avoid interference between the propulsion device and the first support fixing plate 1. Furthermore, since the width of the first portion 11 of the first support fixing plate 1 gradually narrows outward in the generally vertical direction, it can further prevent interference between the propulsion device and the first support fixing plate 1 when it is overturned.

[0065] In some embodiments, the mounting area 31 is arranged along the fourth side 44 and / or the fifth side 45, and the clearance groove 32 has a clearance groove opening formed on the fourth side 44 or the fifth side 45. For example, see... Figure 1 , Figure 3 , Figure 7 As shown, the mounting area 31 is arranged along the fifth side 45, and a clearance groove opening for the clearance groove 32 is formed at the fourth side 44. See, for example, [example not provided]. Figure 5 As shown, the installation area 31 is arranged along the fourth side 44, and the clearance groove opening of the clearance groove 32 is formed at the fifth side 45.

[0066] In some embodiments, one first bracket fixing plate 1 is fixedly connected to the second side 42, and the other first bracket fixing plate 1 is fixedly connected to the third side 43 or the fifth side 45. See, for example... Figure 1 , Figure 3 , Figure 7 As shown, one first bracket fixing plate 1 is fixedly connected to the second side 42, and the other first bracket fixing plate 1 is fixedly connected to the third side 43. See also, for an example... Figure 5 As shown, one first bracket fixing plate 1 is fixedly connected to the second side 42, and the other first bracket fixing plate 1 is fixedly connected to the fifth side 45, so as to allow the bracket to be arranged at a position with a recessed structure in the length direction of the hull.

[0067] In one or more embodiments of this specification, see Figures 9 to 12 As shown, a marine propulsion system may include a bracket 100 and a marine propulsion device 200 mounted on the bracket 100. In some embodiments, at least a portion of the bracket 100 is fixedly connected to the side plate or bulwark of the hull 300.

[0068] In some embodiments, the propulsion device fixing plate 3 of the bracket 100 can be fixed to the underside of the hull 300's side plate via the first bracket fixing plate 1, or the first bracket fixing plate 1 and the second bracket fixing plate 2, so that the marine propulsion device 200 can be fixed to the outer side of the hull, while lowering the center of gravity of the marine propulsion device 200, allowing the lifting rod 210 of the marine propulsion device 200 to carry the thruster 230 to a deeper underwater position. In some embodiments, the installation position of the marine propulsion device 200 can be adjusted by adjusting the installation position of the first bracket fixing plate 1, or the first bracket fixing plate 1 and the second bracket fixing plate 2, relative to the hull 300, thereby adaptively determining the installation height. In some embodiments, the bracket 100 fits snugly against the hull, with a simple and aesthetically pleasing appearance.

[0069] In some embodiments, see Figure 10As shown, a portion of the first bracket fixing plate 1 (e.g., the transverse portion 131 of the third portion) can extend to the upper surface of the hull edge, such as the upper surface of the deck, to provide a better fixing effect. The beneficial effects that the embodiments of this specification may bring include, but are not limited to: (1) the first fixing surface of the first bracket fixing plate is attached to the object to be fixed to adapt to the surface shape of the object to be fixed; (2) the propulsion device fixing plate carries and fixes the propulsion device, and a clearance groove is opened to avoid the propulsion device in part of the structure, so as to allow the propulsion device to perform various functional actions; (3) the strength of the propulsion device fixing plate is increased by arranging an additional second bracket fixing plate, increasing the fixing point of the bracket to the object to be fixed, and dispersing stress; (4) the propulsion device is fixed by setting an installation area and a accommodating space, and leaving space after the propulsion device is flipped, so as to avoid interference between the propulsion device and the bracket after the propulsion device is flipped; (5) the first bracket fixing plate is designed to extend to the object to be fixed. The third part of the upper surface, in conjunction with the second part of the first bracket fixing plate, is fixed to the object from two directions, providing a good fixing effect; (6) The spatial shape of the object to be fixed is obtained by scanning, thereby correspondingly manufacturing the first fixing surface of the first bracket fixing plate so that the first fixing surface can fit with the object to be fixed; (7) The overall weight of the bracket is reduced by opening weight-reducing holes; (8) Through the design of the pentagonal propulsion device fixing plate, a part of the propulsion device fixing plate can protrude from the first bracket fixing plate, thereby allowing the propulsion device to have more room for movement; (9) The first bracket fixing plate can be fixedly connected to the second, third and fifth sides of the propulsion device fixing plate according to environmental requirements, so as to adapt to the bracket fixing when the hull has a concave shape in the length direction. It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects that may be produced can be any one or a combination of the above, or any other possible beneficial effects.
