Description
Technical Field
[0001] The invention relates to the technical field of outboard motors, in particular to an outboard motor with a steering device. Background Art
[0002] An outboard motor is a detachable power device suspended on the stern of a boat or yacht that can propel the boat or yacht to sail. It is also called an outboard motor, boat operating motor, or hanging motor. It is mainly composed of an engine and transmission, operation, suspension device, and propeller. It has the characteristics of compact structure, light weight, easy disassembly, simple operation, and low noise. It is suitable for use in inland rivers, lakes, and offshore. It is often used in the military on boats, yachts, and gate bridges that perform reconnaissance, landing, river crossing, patrol, and other tasks.
[0003] When small portable outboard motors for defense purposes meet the needs of special use environments such as "water airdrops, submarine frogman infiltration", they need to face harsh environmental conditions that conventional products cannot meet. Most of the outboard motors need to be soaked in water, which makes it more difficult to control the outboard motors.
[0004] At present, small outboard motors generally adopt a column structure. When turning, the engine swings as a whole. Considering the engine's deadweight of hundreds of kilograms, using a manual mechanism to control the steering of the column-structured outboard motor consumes a lot of physical energy of the user, resulting in poor operation convenience of the outboard motor. It cannot be replaced with a control mechanism that only acts on the water spray guide port. Such a light operation feel is greatly helpful for the convenience of outboard motor operation and facilitates steering. In view of this, we propose an outboard motor with a steering device.

With the expansion fulcrum 23, more functional components can be optionally expanded, thereby better protecting the outboard motor body and improving applicability. There are six groups of expansion fulcrums 23, and the linear arrays with equal spacing are at the bottom of the load-bearing main tray 2. Under the premise of ensuring watertightness, the following functional components can be expanded: self-hanging fulcrums for expandable mechanical auxiliary installation, self-hanging fulcrums for expandable palletless airdrop, auxiliary handrail installation fulcrums for expandable manual handling, installation fulcrums for expandable emergency floating devices, expandable offshore towing hanging fulcrums, etc.
[0029] Working principle: firstly, after placing the outboard motor body in water, cooperate with the buoyancy provided by the pressure-resistant shell 3 so that the outboard motor body can float in the water and will not sink to the bottom. Note that only the exhaust valve 4 and the intake valve 5 are located above the water surface. When the vertical axis engine 6 is started, the rotating shaft 7 rotates, thereby rotating the active bevel gear 8, thereby cooperating with the transmission of the driven bevel gear 11 to rotate the rotating rod 10 inside the arc-shaped shell 9, thereby rotating the impeller 12, thereby providing the outboard motor body with forward power. Furthermore, when the handle 144 is rotated forward and backward, the mounting seat 141 rotates inside the load-bearing main tray 2 in cooperation with the N-shaped block 142 and the active rod 143, thereby allowing the L-shaped plate 145 to rotate in the horizontal direction. When the handle 144 is swung up and down, the mounting seat 141 rotates inside the load-bearing main tray 2 in cooperation with the N-shaped block 142 and the active rod 143, thereby allowing the L-shaped plate 145 to rotate in the horizontal direction. 4, it can drive the L-shaped plate 145 to swing up and down, so that the connecting rod 147 can rotate horizontally and swing up and down correspondingly in cooperation with the hinge rod 146, so that the arc sleeve 1412 can rotate outside the ball 1410 in cooperation with the cylinder 148 and the disc block 149, so that the arc sleeve 1412 will not fall off and will not affect the rotation of the arc sleeve 1412 in cooperation with the annular groove 1413 and the sliding rod 1414, so that the side plate 1411 can drive the U-shaped plate 1415 and the arc plate 1416 to swing up and down and rotate horizontally in cooperation with the hinge block 1417, so that when the arc plate 1416 moves downward, the range of blocking the water spout 22 is larger, so that the speed can be reduced, and when the arc plate 1416 rotates back and forth, the water flow will be directed to different directions, so The outboard motor body can be conveniently turned forward and backward. Furthermore, when the connecting rod 147 swings up and down, the auxiliary groove 153 slides on the outside of the auxiliary rod 151, so that the auxiliary rod 151 supports the connecting rod 147. When the connecting rod 147 rotates back and forth, the thin groove 155 slides on the outside of the thin rod 154, and at the same time cooperates with the limit plate 152 to prevent the connecting rod 147 from rotating excessively and sliding out of the outside of the auxiliary rod 151, thereby making the steering process of the outboard motor body more stable. Furthermore, when the connecting rod 147 swings up and down, the limit ball 162 slides inside the side groove 161, and the short rod 163 slides inside the short groove 164, so that the short rod 163 causes the long rod 165 to slide between the constraint block 166 and the load-bearing main tray 2 and the pressure-resistant The shell 3 reciprocates up and down inside, so that the round rod 167 and the T-block 168 make the bristles 169 reciprocate up and down, so that the bristles 169 can clean the outside of the intake valve 5 floating above the water surface to avoid long-term dust accumulation affecting the heat dissipation effect. Furthermore, in conjunction with the speed increase transmission box 17, the protective cover 18 and the protective tube 19, it can provide sealing protection for the rotating shaft 7, the active bevel gear 8 and the driven bevel gear 11 to prevent rust damage caused by blisters. In conjunction with the guide fan block 20, the conical cover 21 and the water nozzle 22, the water discharged from the impeller 12 can be better concentrated and discharged, so that the outboard motor body has more power to move forward. In conjunction with the expansion fulcrum 23, more functional components can be optionally expanded, which can better protect the outboard motor body and improve applicability.
