AI Technical Summary
Existing outboard thrusters have limited rotation angles, making it impossible to achieve full azimuth, and reverse rotation leads to a decrease in propulsion efficiency, making it difficult to flexibly switch between full azimuth and half azimuth control.
A switching structure for full-rotation and half-rotation control boxes was designed. The switching between full-rotation and half-rotation is achieved by combining a rotary control push handle, a rotary wheel, a limit component, and a rotary encoder. Direction control is achieved by using the cooperation of the limit slot and the limit component.
It enables full-rotation control when needed, and allows for flexible switching between full-rotation and half-rotation as required, improving the control flexibility and efficiency of the thruster.

[0017] The utility model is further described in detail below by means of the drawings and specific embodiments.
[0018] As Figs. 1-2 The utility model discloses a switching structure of full-rotation control box and half-rotation control box, which comprises a fixed plate 1, a rotating seat 2, a switching assembly and a rotating control handle 3. The rotating control handle 3 is installed on one side of the rotating seat 2. The rotating control handle 3 is connected with a rotating wheel 301. The rotating seat 2 is connected with the fixed plate 1 through a bearing 201. A rotary encoder 203 is installed inside the rotating seat 2. The rotary encoder 203 is opposite to the rotating wheel 301. The switching assembly comprises a limiting groove 101 arranged on the fixed plate 1 and a limiting piece 102 installed on the rotating seat 2. The limiting piece 102 forms a protrusion after being pressed. The protrusion extends into the limiting groove 101. When the rotating seat 2 rotates relative to the fixed plate 1, the limiting piece 102 is limited.
[0019] When installed, the device is sleeved with the fixed plate 1 outside the bearing 201, and the rotating seat 2 is sleeved inside the bearing 201. The circular truncated cone part of the rotating seat 2 comprises the rotating control handle 3 arranged on one side and the limiting groove arranged at the bottom. The limiting piece 102 is arranged in the limiting groove. When the user rotates the rotating control handle, the rotating seat rotates relative to the fixed plate, so that the direction of the propeller controlled by the rotating control handle can be changed. Further, the limiting piece 102 is a spring limiting piece. The spring limiting piece forms a protrusion after being pressed. The protrusion extends into the limiting groove 101. The limiting groove 101 is a U-shaped groove. When the limiting piece is pressed to form a protrusion, the protrusion extends into the limiting groove. Since the limiting groove 101 is a U-shaped groove, when the rotating seat rotates relative to the fixed plate, the limiting piece can only rotate along the U-shaped groove. At this time, half-rotation is formed. Therefore, full-rotation control can be ensured when needed, and full-rotation and half-rotation switching can be performed according to needs.
[0020] The rotating seat 2 comprises a protruding part and a circular truncated cone part. The protruding part is externally provided with a thread, and the thread is connected with the inner wall of the bearing 201. The protruding part is internally provided with a boss, and the boss is used for installing the rotary encoder 203. The middle part of the rotating seat 2 is a cavity, and the cavity is used for accommodating the rotating wheel 301. The rotating control handle 3 is connected with the rotating wheel 301 through a rotating fixing structure.
[0021] The rotating fixing structure comprises a rotating shaft 302, an oil seal 303, a stainless steel fixing sleeve 304 and a damping plate 305; one end of the rotating shaft 302 is connected with the rotating wheel 301, the rear of the rotating wheel 301 is provided with the damping plate 305, the damping plate 305, the stainless steel fixing sleeve 304 and the oil seal 303 are sequentially sleeved on the rotating shaft 302, and the other end of the rotating shaft 302 is connected with the rotating control handle 3. Since one end of the rotating shaft 302 is fixedly connected with the rotating wheel 301 and the other end is connected with the rotating control handle 3, when the handle is manually pulled down or pulled up, the rotating wheel is rotated, at this time, since the encoder is opposite to the rotating wheel, the encoder can collect the rotating signal, and the forward rotation and reverse rotation and rotating speed of each machine can be controlled.
[0022] Obviously, the above embodiments are only examples for clearly illustrating but not limiting the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. All the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the utility model.
