Description

Technical Field

[0001] The present invention relates to the technical field of ship control, and in particular to a remote control device for an electric outboard motor. Background Art

[0002] Outboard motors for small and medium-sized vessels like speedboats and rubber boats primarily consist of a main engine, control devices, and a power source. The main engine includes a gearshift and propeller. When using a marine propeller, the main engine is secured to the vessel via the gearshift, while the propeller is submerged. The propeller's rotation generates propulsion, propelling the vessel forward. The user controls the propeller's thrust and direction via a remote control, thereby steering the vessel. In practice, two propellers are often installed to maximize power and increase speed differential, along with dual side throttles for added convenience.

[0003] The marine mechanical throttle controller converts the rotational motion of the throttle handle into the push-pull of a mechanical cable to achieve throttle control of the marine propeller. It has a complex structure and is inconvenient to operate. It requires a large torque to adjust the throttle size. The gear switching mechanism is complex and has many installation location and distance restrictions. The marine semi-electronic throttle controller is a throttle handle whose rotational motion is read by the main control board and transmitted to the rear electronic throttle cable adjustment box through the communication line. The throttle cable adjustment box actuates and adjusts the throttle. It contains both an electronic sensor and a throttle cable adjustment box that converts the electronic signal into the extension and retraction of the throttle cable. It has a complex structure. To address these issues, Chinese patent application number 202010974733.0 discloses a marine electronic throttle control device, control method, and vessel. The disclosed throttle control device, control method, and vessel comprise: a housing; at least one operating handle rotatably connected to the housing via a damping shaft; and a control assembly disposed within the housing. The control assembly detects the rotation angle of the operating handle and controls the output power of the marine propeller based on the rotation angle. The vessel includes the marine electronic throttle control device and at least one marine propeller. Chinese patent application number 202211098321.0 discloses a control method, a single / dual control device, a movable device in water area and a control system. The control device, movable device in water area and control system disclosed above, the control method is used for a single control device, the single control device can be connected to the same communication system as the power device of the movable device in water area; the single control device can be spliced ​​with another single control device to form a dual control device, and the installation direction of the single control device is opposite to the installation direction of the other single control device; the control method includes: when the single control device and the other single control device are connected to the communication system together, obtaining an operation instruction for the single control device; generating a control signal corresponding to the operation instruction; and sending the control signal to the power device so that the power device acts based on the control signal.

[0004] In the above-mentioned prior art, the damping shaft is driven to rotate synchronously by rotating the operating handle, and then the rotation angle of the operating handle is obtained through the control component and the output power of the marine propeller is controlled by the rotation angle. When the speed of the marine propeller reaches the required speed, the shaft stops rotating to ensure the stability of the ship speed. However, as the ship moves, the ship shakes, and the shaft rotates under the shaking of the ship, which in turn changes the ship speed and makes it impossible to ensure the stability of the ship speed. Summary of the Invention

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] like Figures 1-6 As shown, a remote control device for an electric outboard motor includes a shell 3 and a control handle 1 connected to the shell 3 for controlling the operation of the outboard motor. At least one control handle 1 is provided on the shell 3, and an adjustment mechanism 2 is provided at the end of the control handle 1 for controlling the gear position of the control handle 1; the adjustment mechanism 2 includes a rotating shaft 201 and a sleeve 203 sleeved on the rotating shaft 201 for limiting the rotation angle of the rotating shaft 201, the rotating shaft 201 is provided with a gear tooth 2011, and the sleeve 203 is provided with a clamping member 202 that cooperates with the gear tooth 2011 for positioning the rotation angle of the rotating shaft 201; the shell 3 is provided with a display component 301 electrically connected to the control handle 1 for displaying the operating parameters of the outboard motor.

[0020] Furthermore, the remote control device of the electric outboard motor of the present invention includes a control component and a display component. The specific control component includes a control handle 1 and an adjustment mechanism 2. Each control component can be connected to a propeller. Each housing can be connected to a control component, that is, to control one propeller, or two control components can be connected, that is, to control two propellers. Through the adjustment of the control component, a separate outboard motor can be independently controlled to improve the power of the ship, differential steering, etc., while also improving the convenience of the user in operating the propeller; in addition, the display component 301 will be used in conjunction with the control component. Through the user's adjustment of the control component, the display component 301 will reflect the status of the propeller through a light display. The light display area has a total of twenty gears, and a single propeller is divided into ten gears. The ten-gear light display area corresponds to the speed of the ship propeller and the forward and reverse rotation status of the propeller. The light display feedback improves the user's experience in remotely controlling the outboard motor components.

[0021] The control handle 1 is rotatably connected to the shell 3, and the control handle 1 is connected to the side wall of the shell 3. The adjustment mechanism 2 is located in the shell 3. The adjustment mechanism 2 cooperates with the control handle 1 to adjust the gear of the control handle 1, thereby realizing the adjustment of the ship speed; the rotation shaft 201 is driven to rotate by the control handle 1, and a gear tooth 2011 is provided on the rotation shaft 201, and a sleeve 203 for limiting the rotation angle of the rotation shaft 201 is provided on the rotation shaft 201, and a clamping member 202 is provided on the sleeve 203. When the ship speed reaches the required speed, the clamping member 202 cooperates with the gear tooth 2011 on the rotation shaft 201 to realize the positioning of the rotation shaft 201, thereby ensuring that the rotation shaft 201 will not rotate, thereby ensuring that the ship speed will not change, and improving the stability of the ship during navigation.

[0022] The control handle 1 includes a handle frame 101 and a handle 102 and a rotating part 103 connected to the opposite ends of the handle frame 101. The handle 102 is arranged horizontally, and a silicone sleeve 1021 is sleeved on the handle 102. Furthermore, the handle frame 101, the handle 102 and the rotating part 103 are an integrally molded structure. The handle frame 101 is arranged vertically, the handle 102 is connected to the top of the handle frame 101, and the handle 102 is arranged toward the direction of the shell 3. A silicone sleeve 1021 is sleeved on the handle 102, which increases the connection strength between the handle frame 101 and the handle 102 internally while ensuring comfort, thereby improving the user experience.

[0023] The control handle 1 is divided into three parts: a handle frame 101, a handle 102 and a rotating part 103. The rotating part 103 is connected to the rotating shaft 201 for docking the steering angle, and the rotating part 103 is arranged at the bottom end of the handle frame 101. The rotating part 103 is clamped on the side wall of the shell 3 and rotates on the shell 3; in addition, the handle frame 101 supports the handle 102, and the strength of the handle 102 is increased by the silicone sleeve 1021, thereby reducing the user's actual use stress when operating the propeller. At the same time, when the user operates the propeller, the chrome feel of the rotating shaft 201 and the clamping part 202 is reduced, thereby improving user comfort.

[0024] A limiting ring 1031 is provided on the rotating part 103, and the rotating shaft 201 is connected to the limiting ring 1031. The rotating shaft 201 rotates synchronously with the rotating part 103. Furthermore, the limiting ring 1031 is located on the inner side of the rotating part 103, and the two sides of the limiting ring 1031 are planar structures. The two sides of the end of the rotating shaft 201 are planar structures that are compatible with the limiting ring 1031. The rotating shaft 201 is inserted into the limiting ring 1031, so that the rotating shaft 201 rotates synchronously with the rotating part 103.

[0025] The gear teeth 2011 are arranged on the outer wall of the rotating shaft 201, and the gear teeth 2011 are arranged along the circumferential direction of the rotating shaft 201. Furthermore, the gear teeth 2011 are arranged at the end of the rotating shaft 201, and the gear teeth 2011 are only arranged on the lower side of the rotating shaft 201, that is, the gear teeth 2011 form a semicircular structure around the rotating shaft 201, and are connected with the rotating shaft 201 and the rotating part 103. When the handle 102 is pushed to drive the rotating part 103 to rotate, the rotating shaft 201 rotates at the same time, and the clamping part 202 cooperates with the gear teeth 2011 at the end of the rotating shaft 201 to perform rotation positioning, and at the same time provide a damping feeling during the rotation process to ensure that the gear position of the control handle 1 will not be affected when the ship encounters adverse conditions.

[0026] A protrusion 2012 is provided at the end of the rotating shaft 201, and a limiting groove 2031 is formed on the inner wall of the sleeve 203 to cooperate with the protrusion 2012 for limiting the rotation angle of the rotating shaft 201. The limiting groove 2031 is arranged along the circumferential direction of the sleeve 203. Further, the protrusion 2012 extends outward along the radial direction of the rotating shaft 201. The protrusion 2012 and the gear tooth 2011 are respectively arranged on opposite sides of the rotating shaft 201. The limiting groove 2031 is arranged at the end of the sleeve 203, and The limiting groove 2031 is an arc-shaped structure, and the protrusion 2012 is located in the limiting groove 2031. When the handle 102 is pushed to drive the rotating shaft 201 to rotate, the protrusion 2012 slides in the limiting groove 2031. When the protrusion 2012 slides to the end of the limiting groove 2031, the protrusion 2012 abuts against the groove wall at the end of the limiting groove 2031, thereby achieving the limitation of the rotation angle of the rotating shaft 201, thereby avoiding excessive rotation of the rotating shaft 201, which causes invalid rotation of the control handle 1.

[0027] The clamping member 202 is arranged in the sleeve 203, and the end of the clamping member 202 is in contact with the shift tooth 2011, and the clamping member 202 is an elastic structure. Furthermore, the clamping member 202 is vertically arranged at the end of the sleeve 203, and the cooperation between the clamping member 202 and the shift tooth 2011 realizes the positioning of the rotation angle of the rotating shaft 201. At the same time, by adopting an elastic structure for the clamping member 202, when the rotating shaft 201 rotates, the clamping member 202 is in contact with the shift tooth 2011, thereby avoiding the friction of the clamping member 202 on the shift tooth 2011, which causes the shift tooth 2011 to wear and cause tooth sweeping, and thus the rotating shaft 201 cannot be effectively positioned.

[0028] A pressing piece 204 is sleeved on the rotating shaft 201, and the pressing piece 204 is located between the limiting ring 1031 and the sleeve 203. Furthermore, the pressing piece 204 is fixedly connected to the rotating shaft 201, so that the pressing piece 204 and the rotating shaft 201 rotate synchronously. In addition, a seal 205 for sealing the adjustment mechanism 2 and the control handle 1 is provided on the rotating shaft 201. The seal 205 is located between the pressing piece 204 and the sleeve 203. The seal 205 is subjected to axial pressure from the pressing piece 204, causing the seal 205 to deform, thereby achieving sealing of the control handle 1 and the adjustment mechanism 2.

[0029] The side of the shell 3 is provided with a connecting portion 302 connected to the rotating portion 103, and the bottom of the shell 3 is connected to the lower cover 306. A sealing ring 303 for sealing is provided between the shell 3 and the lower cover 306. Furthermore, the rotating portion 103 is inserted into the connecting portion 302, and the rotating portion 103 is rotatably connected to the connecting portion 302. Through continuous extrusion during the locking process of the shell 3 and the lower cover 306, the sealing ring 303 is deformed to achieve sealing of the connection between the shell 3 and the lower cover 306.

[0030] The display component 301 includes a light board 3011 for displaying parameters. A pressing rib 304 for fixing the light board 3011 is provided in the shell 3. A light blocking plate 305 is provided on the pressing rib 304. The pressing rib 304 is arranged on the inner wall of the shell 3. The pressing rib 304 abuts against the light board 3011. The light blocking plate 305 is arranged on the pressing rib 304. The light blocking plate 305, the pressing rib 304 and the light board 3011 are fixed together by bolts.

[0031] In actual use, Example 1: like Figure 1 As shown, in this embodiment, a control handle 1 is connected to the housing 3 to control a propeller.

[0032] Example 2: like Figure 2 As shown, in this embodiment, a control handle 1 is connected to each side of the shell 3, each control handle 1 controls the left propeller and the right propeller respectively, and each propeller is independently controlled.
