Outboard motor with electrically driven lifting structure

Abstract

This invention discloses an outboard motor with an electrically operated tilting structure, comprising an outboard motor body, a control component for fixing to a vessel mounted on the connecting end of the outboard motor body, and the control component including: a clamping component comprising a sheet metal frame, the lower end of which engages with the stern of the vessel; a rotating component rotatably mounted on the clamping component and engaged with the outboard motor body; and a drive source mounted on the clamping component. Compared with the prior art, the advantages of this invention are that, through the active wheel structure, the driven wheel structure, and the transmission belt, when the outboard motor body tilts due to obstacle avoidance, the laser detector at the lowest end can generate a reverse rotation. This rotation angle exactly cancels out the tilt angle of the outboard motor body, thereby ensuring that the emission direction of the laser beam always remains horizontal, only the height changes. Throughout the entire obstacle avoidance cycle of tilting, hovering, and resetting, the monitoring function of the obstacle in front is not interrupted, although the monitoring height changes.

Description

Technical Field

[0001] This invention relates to the field of outboard motor structure technology, and more particularly to an outboard motor with an electrically operated tilting structure. Background Technology

[0002] When a ship is sailing on water, the outboard motor is a commonly used propulsion device. It is fixed or fastened to the stern of the ship. The propeller and the lower part of the outboard motor extend into the water during navigation to provide propulsion power for the ship.

[0003] However, in shallow waters, nearshore waters, rivers, or lakes, there are underwater obstacles such as reefs, shoals, and driftwood that are difficult to observe. When a ship passes through such areas, if the outboard motor fails to lift in time, its lower hull or propeller is very likely to collide with the underwater obstacles.

[0004] Currently, the common practice is for the driver to visually observe the water ahead and manually control the outboard motor to rotate upwards at a certain angle, causing it to tilt out of the water and avoid direct impact. However, in situations with low visibility, nighttime navigation, or water surface reflection, it is difficult for the driver to accurately and promptly detect underwater obstacles.

[0005] Outboard motors with relatively simple structures and low costs generally do not have any form of automatic obstacle detection or tilt control functions in order to control costs and maintain basic reliability. These models are often only equipped with the most basic manual tilt adjustment function, and the protection of their underwater parts depends entirely on the experience of the pilot. Most ordinary pilots face a high risk of collision when operating outboard motors, especially in unfamiliar waters. Summary of the Invention

[0006] In response to the problems mentioned above, the present invention provides an outboard motor with an electrically operated tilting structure.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an outboard motor with an electric tilting structure, including an outboard motor body, and a control component for fixing to the ship is installed at the connecting end of the outboard motor body. The control component includes: Clamping components, including a sheet metal frame, the lower end of which is engaged with the stern of the vessel; The rotating component is rotatably mounted on the clamping component and is engaged with the outboard motor body; The drive source, mounted on the clamping component, is used to control the rotation angle of the rotating component; The transmission component, one end of which is connected to the rotating component, can have its tilt angle controlled by a drive source; The monitoring component is connected to the other end of the transmission component. It is located at the lower end of the outboard motor body, and the monitoring direction is kept horizontal under the transmission of the transmission component.

[0008] A further preferred embodiment of the present invention is as follows: the clamping component further includes a clamping piece 1 integrally disposed at the lower end of the sheet metal frame, the sheet metal frame having a clamping cavity extending laterally, a clamping piece 2 slidably disposed within the clamping cavity, an adjusting shaft being rotatably mounted inside the clamping cavity, the adjusting shaft passing through the clamping piece 2 and being threadedly connected to the clamping piece 2, and the clamping piece 2 being moved by manually rotating the adjusting shaft.

[0009] A further preferred embodiment of the present invention is: a connector is integrally formed on the outer side of the outboard motor body, and a polygonal hole is passed through the axis of the connector; The sheet metal frame has ears, and the rotating component includes a rotating shaft that is rotatably connected to the ears. The two ends of the rotating shaft are cylindrical, and the middle part is polygonal. The middle part is fitted into the polygonal hole. A driven gear is also fixed on the rotating shaft, and a driving wheel structure is fixed on the outer side of the ear. The rotating shaft and the driving wheel structure are coaxially arranged.

[0010] A further preferred embodiment of the present invention is: two limiting bolts are threadedly connected to the rotating shaft, and the two limiting bolts are respectively located on both sides of the polygonal shape in the middle of the rotating shaft, for limiting the connection.

[0011] A further preferred embodiment of the present invention is as follows: the driving source includes a servo motor fixed on the outside of the sheet metal frame and a drive gear fixed on the output end of the servo motor. The drive gear meshes with the driven gear to drive the rotating shaft to rotate.

[0012] A further preferred embodiment of the present invention is as follows: the monitoring component includes a detachable frame that is detachably fixed to the lower end of the outboard motor body, a rotatable shaft that passes through the detachable frame and is rotatably connected to the detachable frame, a laser detector fixed on the rotatable shaft and oriented horizontally, and a driven wheel structure fixed to the end of the rotatable shaft; The outboard motor has a controller inside, and the laser detector and drive source are all connected to the controller signal.

[0013] A further preferred embodiment of the present invention is: the transmission component includes an inner cover plate, an outer cover plate, and a transmission belt; The inner cover plate is attached to the outside of the sheet metal frame. The rotating shaft and the rotatable shaft both pass through the inner cover plate. The drive wheel structure also passes through the inner cover plate. The driven wheel structure is located on the outside of the inner cover plate. The transmission belt is set on the drive wheel structure and the driven wheel structure. When the tilt angle of the monitoring component changes, the laser detector is kept in a horizontal orientation.

[0014] A further preferred embodiment of the present invention is that the driving wheel structure and the driven wheel structure are the same size.

[0015] A further preferred embodiment of the present invention is that both the driving wheel structure and the driven wheel structure have meshing grooves on their outer sides, and the transmission belt has meshing teeth that cooperate with the meshing grooves on its inner side.

[0016] A further preferred embodiment of the present invention is: an outer cover plate is provided on the outer side of the inner cover plate to cover the internal driving wheel structure, driven wheel structure and transmission belt, and the edge of the outer cover plate is narrowed.

[0017] Compared with the prior art, the advantages of the present invention are as follows: 1. Through the active wheel structure, driven wheel structure and transmission belt, when the outboard motor body tilts up due to obstacle avoidance, the laser detector at the lowest end can generate a reverse rotation. This rotation angle just cancels the tilt angle of the outboard motor body, thus ensuring that the laser beam emission direction always remains horizontal, only the height changes. During the entire obstacle avoidance cycle of tilting, hovering and resetting, the monitoring function of the obstacle in front will not be interrupted, and the monitoring height will change.

[0018] 2. After the laser detector detects an obstacle, the signal is transmitted to the controller, which drives the servo motor to tilt the outboard motor to avoid the obstacle. After the controller finishes timing, it attempts to drive the reset. If the laser detector detects an obstacle again during the reset process, the reset is immediately interrupted and the tilting starts again. The timing is then restarted to achieve collision protection. The tilting angle is the angle at which the laser detector cannot detect the obstacle.

[0019] 3. The control components are mechanical transmission structures, which can keep the laser detector in a horizontal position. The structure is simple, low in cost, and not easily damaged. The monitoring components adopt a detachable design, which can be easily replaced when the laser detector is damaged or needs maintenance, reducing maintenance costs. Attached Figure Description

[0023] Preferred embodiments of the present invention will now be described in detail 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.

[0024] 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.

[0025] This embodiment mainly describes an outboard motor with an electrically operated tilting mechanism. Please refer to [link / reference needed]. Figures 1-8 Specifically, the outboard motor with an electrically operated tilting structure includes an outboard motor body 1. A control component 2 for fixing the outboard motor body 1 to the ship is installed at its connecting end. The control component 2 includes: Clamping component 21 includes sheet metal frame 211, the lower end of sheet metal frame 211 being snapped into the stern of the ship; Rotating component 23 is rotatably mounted on clamping component 21 and engaged with outboard motor body 1; The drive source 22 is mounted on the clamping component 21 and is used to control the rotation angle of the rotating component 23; The transmission component 24 is connected at one end to the rotating component 23 and its tilt angle can be controlled by the drive source 22. The monitoring component 25 is connected to the other end of the transmission component 24. It is located at the lower end of the outboard motor body 1, and the monitoring direction is kept horizontal under the transmission of the transmission component 24.

[0026] Specifically, the outboard motor body 1 is fixed to the ship by the clamping component 21, and the rotating component 23 is driven by the drive source 22 to realize the electric tilting of the outboard motor body 1. Through the monitoring component 25 and the transmission component 24, the laser emission direction of the monitoring component 25, which is located at the bottom of the outboard motor body 1 and is used to detect obstacles in front, can be automatically compensated by the transmission component 24 and kept horizontal when the outboard motor body 1 tilts due to obstacle avoidance, thereby ensuring that the monitoring function continuously monitors obstacles horizontally during obstacle avoidance and reset.

[0027] like Figure 4 As shown, the clamping component 21 also includes a clamping piece 213 integrally disposed at the lower end of the sheet metal frame 211. The sheet metal frame 211 has a clamping cavity 212 extending horizontally through it. A clamping piece 214 is slidably disposed inside the clamping cavity 212. An adjusting shaft 215 is rotatably mounted inside the clamping cavity 212. The adjusting shaft 215 passes through the clamping piece 214 and is threadedly connected to the clamping piece 214. The clamping piece 214 can be moved by manually rotating the adjusting shaft 215.

[0028] Specifically, the clamping component 21 uses a structure of fixed clamping plate 1 213 and adjustable clamping plate 214 to fix and limit the outboard motor body 1. The clamping force is adjusted by adjusting shaft 215. It can be clamped on ships of different thicknesses. It should be noted that the clamping cavity 212 and clamping plate 214 are T-shaped, so that clamping plate 214 is perpendicular to sheet metal frame 211. The side of clamping plate 1 213 and clamping plate 214 that are close to each other have a layer of rubber anti-slip structure.

[0029] like Figure 4 As shown, a connector 11 is integrally formed on the outer side of the outboard motor body 1, and a polygonal hole 12 passes through the axis of the connector 11; The sheet metal frame 211 has an ear 216, and the rotating component 23 includes a rotating shaft 231 that is rotatably connected to the ear 216. The two ends of the rotating shaft 231 are cylindrical, and the middle part is polygonal. The middle part is fitted into the polygonal hole 12. A driven gear 233 is also fixed on the rotating shaft 231, and a driving wheel structure 234 is fixed on the outer side of the ear 216. The rotating shaft 231 and the driving wheel structure 234 are coaxially arranged.

[0030] Specifically, the connector 11 is connected to the rotating shaft 231 through a polygonal hole 12 and a polygonal shaft, so that the connector 11 moves with the rotating shaft 231 when the rotating shaft 231 rotates.

[0031] like Figure 4 As shown, two limiting bolts 232 are threadedly connected to the rotating shaft 231. The two limiting bolts 232 are located on both sides of the polygonal shape in the middle of the rotating shaft 231, and are used to limit the connection 11.

[0032] Specifically, two limit bolts 232 lock the connecting parts 11 from both sides to prevent the outboard motor body 1 from accidentally moving or falling off along the axis of the rotating shaft 231 during operation. At the same time, the locking method of the limit bolts 232 also facilitates disassembly and maintenance.

[0033] like Figure 4 As shown, the drive source 22 includes a servo motor 221 fixed on the outside of the sheet metal frame 211 and a drive gear 222 fixed on the output end of the servo motor 221. The drive gear 222 meshes with the driven gear 233 to drive the rotating shaft 231 to rotate.

[0034] Specifically, a servo motor 221 is used to provide power, and the drive gear 222 meshes with the driven gear 233 to realize the rotation of the rotating shaft 231, thereby driving the outboard motor body 1 to tilt or return to its original position.

[0035] like Figure 5 As shown, the monitoring component 25 includes a detachable frame 251 that is detachably fixed to the lower end of the outboard motor body 1, a rotatable shaft 252 that passes through the detachable frame 251 and is rotatably connected to the detachable frame 251, a laser detector 253 that is fixed on the rotatable shaft 252 and is oriented horizontally, and a driven wheel structure 254 is fixed to the end of the rotatable shaft 252. The outboard motor body 1 has a controller inside, and the laser detector 253 and the drive source 22 are both connected to the controller signal.

[0036] Specifically, the laser detector 253 is mounted at the bottom of the outboard motor body 1 via a detachable frame 251, ensuring that its monitoring position is at the bottom of the outboard motor body 1 and that obstacles affecting the outboard motor body 1 can be detected. The detachable design facilitates installation and maintenance. The laser detector 253 is connected to the controller and can provide real-time feedback on obstacles ahead. The driven wheel structure 254 is fixed to the end of the rotatable shaft 252 and can drive the laser detector 253 to rotate along the detachable frame 251. The controller receives the signal from the laser detector 253 and controls the drive source 22 accordingly, forming a complete control closed loop.

[0037] like Figure 3 and Figure 5 As shown, the transmission component 24 includes an inner cover plate 241, an outer cover plate 242, and a transmission belt 243; The inner cover plate 241 is attached to the outside of the sheet metal frame 211. The rotating shaft 231 and the rotatable shaft 252 both pass through the inner cover plate 241. The driving wheel structure 234 also passes through the inner cover plate 241. The driven wheel structure 254 is located on the outside of the inner cover plate 241. The transmission belt 243 is driven on the driving wheel structure 234 and the driven wheel structure 254. When the tilt angle of the monitoring component 25 changes, the laser detector 253 is kept in a horizontal orientation.

[0038] Specifically, the drive belt 243 connects the drive wheel structure 234 and the driven wheel structure 254. When the outboard motor body 1 tilts up, that is, the rotating shaft 231 rotates while the drive wheel structure 234 remains stationary. The drive belt 243 forces the driven wheel structure 254 to generate a reverse rotational motion, that is, the tilting angle of the outboard motor body 1 is equal to the rotation angle of the driven wheel structure 254. The inner cover plate 241 and the outer cover plate 242 constitute a protective shell to prevent water flow and debris from interfering with it, so that the laser detector 253 always remains horizontal no matter how the outboard motor body 1 is tilted. The structure is also relatively simple.

[0039] The drive wheel structure 234 and the driven wheel structure 254 are the same size. When the drive wheel structure 234 and the driven wheel structure 254 are the same, under the linkage of the transmission belt 243, the driven wheel structure 254 will rotate in the opposite direction around its own axis by the same angle as the center line of the rotating shaft 231 rotates, so that the reverse rotation angle of the laser detector 253 is exactly equal to the tilt angle of the outboard motor body 1, thus keeping the laser detector 253 horizontal.

[0040] like Figure 5 As shown, both the driving wheel structure 234 and the driven wheel structure 254 have meshing grooves on their outer sides, and the transmission belt 243 has meshing teeth on its inner side that cooperate with the meshing grooves.

[0041] Specifically, the engagement of the meshing groove and the meshing teeth can prevent slippage that may occur during friction transmission, thus ensuring the level of the laser detector 253.

[0042] An outer cover plate 242 is provided on the outer side of the inner cover plate 241 to cover the internal drive wheel structure 234, driven wheel structure 254 and transmission belt 243. The edge of the outer cover plate 242 is narrowed.

[0043] Specifically, the outer cover 242 is a protective cover that effectively prevents impurities and foreign objects from getting caught in, which could lead to transmission failure or damage. Its narrowed edges help reduce navigation resistance in water.

[0044] Working principle: The clamping component 21 drives the second clamping piece 214 to move along the clamping cavity 212 by manually rotating the adjusting shaft 215, thereby changing the distance between the first clamping piece 213 and the second clamping piece 214, so that it is clamped at the stern of the ship. The lower half of the outboard motor body 1 extends into the water. The laser detector 253 is located at the bottom of the outboard motor body 1. The laser detector 253 emits a laser in front of the horizontally moving body. Currently, the effective detection range of the underwater laser detector 253 is usually between 5 meters and 50 meters, depending on the water conditions. When the laser detector 253 detects an obstruction, it generates a signal and transmits it to the controller. The controller drives the servo motor 221 to work, tilting the outboard motor body 1.

[0045] As described above, after the outboard motor body 1 tilts up, the monitoring component 25 tilts up as well, and therefore the transmission component 24 also moves accordingly. Based on this, and since the drive pulley structure 234 is fixed, and the drive pulley structure 234 and the driven pulley structure 254 are the same size, when the transmission belt 243 tilts up... Figure 8 As shown, the transmission belt 243 changes its engagement position with the drive wheel structure 234, so that the rotational angular velocity of the driven wheel structure 254 is equal in magnitude and opposite in direction to its angular velocity of revolution along the drive wheel structure 234. When the position of the driven wheel structure 254 changes, its orientation remains unchanged, so that the laser detector 253 remains horizontal and is used to monitor obstacles in the horizontal direction at the lowest position of the outboard motor body 1.

[0046] It should be noted that the existing controller has a pulse function. After the servo motor 221 drives the outboard motor body 1 to tilt, it counts for one minute or a fixed time to reset the servo motor 221. When the outboard motor body 1 is reset, the laser detector 253 still detects the obstruction, keeps the outboard motor body 1 in the tilted state, and restarts the timing.

[0047] The specific process is as follows: When laser detector 253 detects an obstacle, the controller receives a signal and activates servo motor 221. The upward tilting angle continues until laser detector 253 no longer detects an obstacle. After a fixed time has elapsed, the controller sends a pulse, and servo motor 221 resets. If, during the downward movement of laser detector 253, an obstacle is detected, servo motor 221 reverses its direction, tilting the outboard motor body 1 upwards again. Figure 7 The transmission component 24 and the monitoring component 25 are in the reset state, such as Figure 8 The transmission component 24 and the monitoring component 25 are in the tilted state. It should be noted that the tilting angle in the tilted state is determined by the height of the obstacle detected by the laser detector 253. It should also be noted that the underwater laser detector 253 and controller are existing structures.

[0048] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use.

Therefore, they should not be construed as limiting this invention.
