Outboard motor boom structure

Abstract

This utility model discloses an outboard motor boom structure, comprising: a steering sleeve fitted onto the outboard motor; a clamping plate located outside the steering sleeve for clamping with the hull; a fastening ring rotatably disposed outside the steering sleeve to allow the steering sleeve to rotate; and a pitch section disposed between the fastening ring and the clamping plate for adjusting the angle between the steering sleeve and the clamping plate. The pitch section includes a fixed disc mounted to the fastening ring, the fixed disc being covered by a clamping member, an adjusting plate being provided on the outside of the clamping member, and an adjusting component between the adjusting plate and the clamping member. Compared with the prior art, the advantage of this utility model is that when the pitch angle needs to be adjusted, rotating the fixed disc forces the ball to exit from one disc hole and fall into the next adjacent disc hole. This process produces a noticeable shifting sensation, allowing the operator to accurately perceive and locate the specific pitch angle.

Description

Technical Field

[0001] This utility model relates to the field of marine propulsion technology, and in particular to an outboard motor boom structure. Background Technology

[0002] The outboard motor boom structure is a core component of the outboard engine. Located below the engine cylinder block or power head and above the water, it plays a crucial role in transmitting all the forces generated by the engine to the hull. At the same time, it also serves as a bridge for transmitting navigation inputs.

[0003] Outboard booms typically feature adjustment mechanisms that allow the owner or helmsman to alter the tilt angle of the outboard motor relative to the stern, adjusting the stern draft and the hull's angle of travel to reduce drag and improve navigation efficiency, stability, and speed. In shallow waters, the propeller is raised to prevent collisions; at high speeds, the optimal propulsion angle is adjusted; and in rough seas, the attitude is adjusted to improve seaworthiness. Furthermore, the outboard boom supports the outboard motor, and the helmsman, through steering force applied by the rudder wheel or rudder handle, rotates the outboard motor within the boom structure, thus steering the vessel.

[0004] With its simple outboard motor and boom structure, the outboard motor can be easily steered and its tilt angle relative to the stern can be changed, making it suitable for simple fishing boats and offering greater operational flexibility. However, for beginners, changing the direction of the outboard motor's propulsion can be difficult to control. During the lifting process, the propeller may partially or completely leave the water, causing slippage and a momentary interruption of power output. Therefore, a gear mechanism is needed to precisely control the outboard motor's tilt angle. Utility Model Content

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an outboard motor boom structure, comprising:

[0007] Steering sleeve, fitted onto the outboard motor;

[0008] The clamping plate is located on the outside of the steering sleeve and is used to clamp the hull.

[0009] The fastening ring is rotatably mounted on the outside of the steering sleeve to allow the steering sleeve to rotate.

[0010] The pitch section, located between the fastening ring and the clamping base plate, is used to adjust the angle between the steering sleeve and the clamping base plate. The pitch section includes a fixed plate mounted with the fastening ring, a clamping member covering the fixed plate, an adjusting plate on the outside of the clamping member, an adjusting component between the adjusting plate and the clamping member, and a clamping component between the adjusting plate and the clamping member. The degree of compression between the adjusting component and the fixed plate is controlled by adjusting the clamping component to adjust the pitch resistance.

[0011] A further preferred embodiment of this utility model is: the fastening ring is an open annular shape, the outer wall of the steering sleeve has at least two limiting rings integrally formed, the fastening ring is sandwiched between the two limiting rings, and the opening of the fastening ring is fixedly connected by bolts.

[0012] A further preferred embodiment of this utility model is: the outer side of the fastening ring has an integral protruding layer, the outer end face of the protruding layer is a vertical plane, and it is fixed to the fixing plate.

[0013] A further preferred embodiment of this utility model is: the outer end face of the fixed disk has a plurality of disk holes distributed along the circumference of the fixed disk, the clamping member has a mating hole corresponding to the disk holes, the mating hole is connected to the interior of the clamping member, the adjusting member is pushed by the adjusting plate and located in the corresponding mating hole, and the end of the adjusting member is locked in the disk hole.

[0014] A further preferred embodiment of this utility model is: the adjusting component includes a shaft fixed inside the adjusting plate, a spring fixed at the outer end of the shaft, a retaining ball fixed at the end of the spring, the shaft, the spring and the retaining ball are all located in the mating hole, and the outward part of the retaining ball abuts against the disc hole.

[0015] A further preferred embodiment of this utility model is: the diameter of the shaft and the ball is the same as the inner diameter of the mating hole, the diameter of the disc hole is also the same as the diameter of the ball, and the volume of the disc hole cavity is one-third of the volume of the ball.

[0016] A further preferred embodiment of this utility model is: the clamping component includes an adjusting bolt fixed to the outer end face of the clamping member, the adjusting bolt passes through the adjusting plate outward, and the outer side of the adjusting plate has an adjusting nut that is threadedly connected to the adjusting bolt, and the adjusting component is controlled to be squeezed by rotating the adjusting nut.

[0017] A further preferred embodiment of this utility model is: the clamping member is divided into two halves, with the two halves of the clamping member approaching the middle from both sides of the fixed plate to cover the fixed plate, and the two halves of the clamping member are fixed to each other by bolts.

[0018] A further preferred embodiment of this utility model is: each of the two halves of the clamping member has a fixed threaded shaft that is set in half, and the two halves of the fixed threaded shaft cooperate with each other and pass through the adjusting plate;

[0019] Both halves of the fixed threaded shaft have an integral base surface on their outer walls. The clamping plate is sleeved on the two halves of the fixed threaded shaft and abuts against the base surface. The two halves of the fixed threaded shaft are threaded with clamping nuts for pressing and fixing the clamping plate.

[0020] A further preferred embodiment of this utility model is: the lower end of the clamping base plate has a clamping cavity for clamping the hull, and a clamping screw is also threaded onto the clamping base plate for clamping the hull in the clamping cavity.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] 1. The pitch section can control the rotational resistance between the fixed plate and the clamping parts. During navigation or turbulence, the outboard motor will not easily change the preset pitch angle due to its own weight or the impact of water flow, which greatly reduces the risk of misoperation.

[0023] 2. When the pitch angle needs to be adjusted, rotating the fixed plate will force the ball to exit from one plate hole and fall into the next adjacent plate hole. This process will produce a noticeable shifting sensation, allowing the operator to accurately perceive and locate the specific pitch angle.

[0024] 3. By tightening or loosening the clamping components, the pressure of the spring can be changed, which in turn changes the pressure of the ball clamping mechanism, thus altering the strength of the gear shifting feel. The operator can find the most suitable gear shifting feel intensity based on personal preference, operating environment, or outboard motor horsepower. Attached Figure Description

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0034] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0035] This embodiment mainly describes the outboard motor boom structure; please refer to [link / reference needed]. Figures 1-6 Specifically, as follows: Many cruise ships or fishing boats are equipped with detachable and simple outboard motors to drive the boat. The outboard motor is connected to the hull through a boom structure, which also enables the outboard motor to turn and tilt at the stern. For a simple boom structure, the turning and tilt angle at the stern can be easily changed. Different people have different levels of operational difficulty. Some operators find it easier to operate because the turning and tilt angle at the stern can be easily changed, while others find it more difficult. Based on this, an outboard motor boom structure is proposed, including a steering sleeve 1, a clamping base plate 4, a fastening ring 2, and a pitching part 3.

[0036] Steering sleeve 1 is fitted onto the outboard motor;

[0037] The clamping plate 4 is located on the outside of the steering sleeve 1 and is used to clamp the hull.

[0038] The fastening ring 2 is rotatably disposed on the outside of the steering sleeve 1 to allow the steering sleeve 1 to rotate;

[0039] The pitch section 3 is disposed between the fastening ring layer 2 and the clamping base plate 4, and is used to adjust the angle between the steering sleeve 1 and the clamping base plate 4. The pitch section 3 includes a fixed plate 31 installed with the fastening ring layer 2. The fixed plate 31 is covered with a clamping member 32. An adjusting piece 33 is provided on the outside of the clamping member 32. An adjusting component 34 is provided between the adjusting piece 33 and the clamping member 32. A clamping component 35 is also provided between the adjusting piece 33 and the clamping member 32. The degree of compression between the adjusting component 34 and the fixed plate 31 is controlled by adjusting the clamping component 35 to adjust the pitch resistance.

[0040] Specifically, the steering sleeve 1 is connected to the outboard motor and is detachably fixed inside the steering sleeve 1. The clamping plate 4 is fixed to the hull by the clamping screw 6. All of this is existing technology. The pitch part 3 is located between the fastening ring 2 and the clamping plate 4. When the pitch angle of the steering sleeve 1 changes, the pitch part 3 will produce a jerking sensation to improve the operator's operating feel. It should be noted that the degree of jerking sensation can be adjusted to suit different operators.

[0041] like Figures 1-2 As shown, the fastening ring 2 is an open annular shape, and the outer wall of the steering sleeve 1 has at least two limiting rings 11 integrally formed. The fastening ring 2 is clamped between the two limiting rings 11, and the opening of the fastening ring 2 is fixedly connected by bolts.

[0042] Specifically, the fastening ring 2 and the steering sleeve 1 are rotatably connected. When the outboard motor rotates, the steering sleeve 1 rotates while the position of the fastening ring 2 remains unchanged. It should be noted that the two limiting rings 11 limit the fastening ring 2 to make it stable.

[0043] like Figure 3 As shown, the outer side of the fastening ring 2 has an integral protruding layer 21, the outer end face of the protruding layer 21 is a vertical plane, and it is fixed to the fixing plate 31.

[0044] Specifically, the outer side of the fastening ring 2 has an integral protruding layer 21, which can stably fix the fixed plate 31 and enhance stability during pitching.

[0045] like Figures 3-4 The following is a detailed description of the fixed disk 31 and the clamping member 32. The outer end face of the fixed disk 31 has a number of disk holes 311 distributed along the circumference of the fixed disk 31. The clamping member 32 has a mating hole 321 corresponding to the disk holes 311. The mating hole 321 communicates with the interior of the clamping member 32. The adjusting member 34 is pushed by the adjusting piece 33 and is located in the corresponding mating hole 321. The end of the adjusting member 34 is locked in the disk hole 311.

[0046] Specifically, the disk hole 311 on the fixed disk 31 engages with the mating hole 321 of the clamping member 32, and the adjusting member 34 passes through the mating hole 321 and abuts against the disk hole 311. When rotation occurs between the disk hole 311 and the mating hole 321, the adjusting member 34 is driven to retract into the mating hole 321, resulting in resistance and a jerking sensation.

[0047] like Figure 5 The detailed structure of the adjusting component 34 is shown. The adjusting component 34 includes a shaft 341 fixed inside the adjusting plate 33, a spring 342 fixed at the outer end of the shaft 341, and a retaining ball 343 fixed at the end of the spring 342. The shaft 341, the spring 342 and the retaining ball 343 are all located in the mating hole 321, and the outward part of the retaining ball 343 abuts against the disc hole 311.

[0048] Specifically, the shaft 341, spring 342, and ball 343 of the adjusting component 34 are all located inside the mating hole 321. The adjusting component 34 presses inward along the mating hole 321, controlling the ball 343 to press against the disc hole 311. Under the pressing action, the disc hole 311 and the mating hole 321 rotate to produce a jerking sensation, and the jerking sensation is maintained. When the pressing force changes, the magnitude of the jerking sensation changes.

[0049] like Figure 4 and Figure 5 As shown, the diameters of the shaft portion 341 and the retaining ball 343 are the same as the inner diameter of the mating hole 321, and the diameter of the disc hole 311 is also the same as the diameter of the retaining ball 343. Furthermore, the cavity of the disc hole 311 is one-third the volume of the retaining ball 343.

[0050] It should be noted that the shaft 341 can slide within the mating hole 321, and the same ball 343 can also slide within the mating hole 321 without any positional shift. The spring 342 is in a compressed state, with part of the ball 343 located within the mating hole 321 and one-third within the disc hole 311. When rotation occurs between the disc hole 311 and the mating hole 321, the ball 343 is ensured to retract into the mating hole 321, resulting in a jerking motion. The degree to which the spring 342 is compressed controls the magnitude of the jerking sensation. The greater the degree to which the spring 342 is compressed, the greater the jerking sensation, and vice versa.

[0051] like Figure 4 and Figure 6 As shown, the clamping component 35 includes an adjusting bolt 351 fixed to the outer end face of the clamping component 32. The adjusting bolt 351 extends outward through the adjusting plate 33. The outer side of the adjusting plate 33 has an adjusting nut 352 that is threadedly connected to the adjusting bolt 351. The adjusting component 34 is controlled to be in a compressed state by rotating the adjusting nut 352.

[0052] Specifically, the clamping component 35 is used to control the degree of compression of the spring 342, so that the jerking sensation can be adjusted to suit different operators, and is controlled by rotating the adjusting nut 352.

[0053] like Figures 2-3 As shown, the clamping member 32 is divided into two halves. The two halves of the clamping member 32 approach the middle from both sides of the fixed plate 31 and cover the fixed plate 31. The two halves of the clamping member 32 are fixed to each other by bolts.

[0054] Specifically, the clamping member 32 is designed to cooperate with the fixed plate 31 by means of its shape, and the two halves of the clamping member 32 clamp from both sides of the fixed plate 31 respectively, so that the clamping member 32 and the fixed plate 31 are in full contact and cooperate, ensuring the smooth operation of the adjusting component 34.

[0055] like Figures 2-3 As shown, each of the two halves of the clamping member 32 has a fixed threaded shaft 36 that is set in half. The two halves of the fixed threaded shaft 36 cooperate with each other and pass through the adjusting piece 33.

[0056] Both halves of the fixed threaded shaft 36 have an integral base surface 361 on their outer walls. The clamping plate 4 is sleeved on the two halves of the fixed threaded shaft 36 and abuts against the base surface 361. The two halves of the fixed threaded shaft 36 are threaded with clamping nuts 41 for pressing and fixing the clamping plate 4.

[0057] Specifically, the clamping member 32 and the clamping base plate 4 are engaged by the two fixed threaded shafts 36, and the clamping base plate 4 is supported on the base surface 361 by the clamping nut 41.

[0058] like Figure 1 As shown, the lower end of the clamping base plate 4 has a clamping cavity 5 for clamping the hull, and a clamping screw 6 is threadedly connected to the clamping base plate 4 for clamping the hull within the clamping cavity 5. Specifically, the clamping base plate 4 is a conventional structure of the hanging arm, and both the clamping cavity 5 and the clamping screw 6 are existing technologies.

[0059] Working principle: The connection between the outboard motor and the boom is existing technology. The boom is fixed to the outboard motor through the steering sleeve 1, and the boom is clamped to the hull through the clamping plate 4. The clamping plate 4 is fixed to the hull by rotating the clamping screw 6.

[0060] Specifically, the fastening ring 2 is sleeved with the steering sleeve 1, allowing the steering sleeve 1 to rotate within the fastening ring 2, thereby controlling the direction of the outboard motor. Secondly, the pitch part 3 is used, and the fixed plate 31 of the pitch part 3 is connected to the fastening ring 2. The clamping member 32 is rotatable, and the resistance between the fixed plate 31 and the clamping member 32 is controlled by the adjusting component 34, so that there is resistance when the outboard motor changes the pitch angle. In addition, the magnitude of the resistance can be controlled by the clamping component 35 to prevent the outboard motor from being accidentally operated and changing the pitch angle.

[0061] It should be noted that the adjusting component 34 controls the resistance between the fixed plate 31 and the clamping member 32. The retaining ball 343 of the adjusting component 34 abuts against the plate hole 311. When the fixed plate 31 and the clamping member 32 rotate, the retaining ball 343 is forced back into the mating hole 321, and then the retaining ball 343 abuts against the next plate hole 311. It should also be noted that this setting produces a tactile feedback of a certain level of engagement, allowing for more precise control. Furthermore, the clamping component 35 can be used to tighten the clamping mechanism, changing the degree of engagement and allowing for precise adjustment to meet the needs of different users.
