[0002] Marine push-back propellers, also known as outboard motors, are widely used to drive small boats. Existing outboard motors often achieve heading control by installing a control handle at the upper end of the main rod, and manually pushing the handle to adjust the direction of the propeller at the lower end of the main rod. However, this operation method occupies the operator's hands, and it is difficult to achieve 360-degree angle control, which is inconvenient to use. Although replacing the outboard motor with an outboard motor that can be electrically controlled to steer can solve the above problems, it requires replacing the outboard motor as a whole, which requires major changes and has a high implementation cost. For this reason, it is necessary to propose a new electric steering solution for outboard motors. Utility Model Content

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below. Figures 1 to 3 The embodiment of the utility model provides an external steering device, including a steering box 100, a main gear 200, a main rod connecting member 300, a driving device and a fixing seat 500. The steering box 100 is composed of a left half box 120 and a right half box 110, and after the assembly, a first through hole is provided at the assembly for the main rod of the outboard motor to pass through. The main gear 200 is rotatably arranged in the steering box 100, and is composed of a left half gear 210 and a right half gear 220, and after the assembly, a second through hole is provided at the assembly for the main rod to pass through, and the second through hole is concentric with the first through hole. The main rod connecting member 300 is used to connect the main gear 200 with the main rod, and is detachably connected to the main gear 200 and the main rod respectively. The rotation driving device 400 is arranged in the left half box 120 or the right half box 110, and is used to drive the main gear 200 to rotate. The fixing seat 500 is used to fix the steering box 100 with the fixing frame of the outboard motor.

[0024] The external steering device of the embodiment of the utility model, the main gear 200 and the steering box 100 are both of a left-right spliced ​​structure, which is convenient for installation on the main rod of the outboard motor. The main gear 200 can be connected to the main rod through the main rod connector 300, and the steering box 100 can be fixed to the fixed frame of the outboard motor through the fixing seat 500, so that the rotary drive device 400 can drive the main gear 200 to rotate by driving the transmission gear 410, thereby driving the main rod to rotate, and realizing the electric steering control of the outboard motor. The external steering device of the embodiment of the utility model can be installed on the main rod of the outboard motor without disassembling the outboard motor, and the electric steering control modification of the outboard motor can be realized without replacing the outboard motor as a whole. It is easy to install and reduces the cost of the electric steering control modification of the ship.

[0025] It is understandable that the main rod connector 300 can be detachably connected to the main rod and the main gear 200 by means of clamping, bolt connection, or latching. Figure 3 and Figure 4 In this embodiment, in order to avoid irreversible modification such as threaded holes on the main pole, which affects the strength of the main pole, and to change the height of the external steering device on the main pole according to the height of the fixing frame of the outboard motor, the main pole connecting member 300 is connected to the main pole by clamping. The main pole connecting member 300 includes a left clamping member 310 and a right clamping member 320. After the left clamping member 310 and the right clamping member 320 are assembled, the main pole can be clamped between the two. In this embodiment, in order to clamp the cylindrical main pole more stably, the left clamping member 310 and the right clamping member 320 are both arc-shaped. At the same time, in order to prevent the left clamping member 310 and the right clamping member 320 from being lost after being separated, one end of the left clamping member 310 and the right clamping member 320 are hinged together, and the other ends of the left clamping member 310 and the right clamping member 320 are each provided with an adjustment seat 301, and the adjustment seat 301 is provided with a bolt hole for an adjusting bolt, and one end of the adjusting bolt is provided with an adjustment handle 302 to rotate the adjusting bolt. The bottom of the left clamping member 310 and the right clamping member 320 are both provided with a first tooth portion, and the side wall of the second through hole of the main gear 200 is provided with a second tooth portion matching the first tooth portion. The left clamping member 310 and the right clamping member 320 can realize the detachable connection between the main rod connecting member 300 and the main gear 200 by meshing the first tooth portion with the second tooth portion. When the main gear 200 rotates under the drive of the rotary drive device 400, the torque is transmitted to the main rod connecting member 300 through the second tooth portion and the first tooth portion, and then transmitted to the main rod through the main rod connecting member 300, so that the main rod rotates with the main gear 200. Figure 4 In this embodiment, in order to facilitate the plug-in engagement of the first tooth portion and the second tooth portion, the teeth of the first tooth portion are narrow at the bottom and wide at the top, and the tooth grooves of the second tooth portion are correspondingly wide at the top and narrow at the bottom, so as to form a guide during insertion and engagement.

[0026] Reference Figure 2 and Figure 3In this embodiment, in order to facilitate the installation of the main gear 200, the rotation drive device 400 and the transmission gear 410, the left half box 120 is composed of a left upper cover 121 and a left lower box body 122, and the right half box 110 is composed of a right upper cover 111 and a right lower box body 112. The left upper cover 121 and the right upper cover 111 are connected to the left lower box body 122 and the right lower box body 112 respectively by bolts. The rotation drive device 400 mainly adopts a motor, which can be a servo motor or a stepper motor, etc. The lower left box body 122 is provided with a motor compartment for accommodating the motor. The output shaft of the rotation drive device 400 is provided with a transmission gear 410, which is meshed with the main gear 200 to drive the main gear 200 to rotate. The radius of the main gear 200 is generally much larger than the radius of the transmission gear 410, so as to reduce the rotation speed of the main gear 200 and amplify the torque output by the rotation drive device 400.

[0027] Reference Figure 3 In this embodiment, for the convenience of installation, one end of the lower left box body 122 and the lower right box body 112 are hinged, and the other end is detachably connected through a locking mechanism. The locking mechanism can be a relatively reliable and easy to disassemble mechanism such as a buckle or a bolt. In this embodiment, the locking mechanism includes two locking seats 103 and locking bolts arranged on the lower left box body 122 and the lower right box body 112. Bolt holes for locking bolts are arranged on the two locking seats 103. After the left half box 120 and the right half box 110 are assembled, the two locking seats 103 are fitted together, and the two locking seats 103 are fixed together by passing the locking bolt through the two locking seats 103. A locking handle 104 is arranged at one end of the locking bolt to facilitate the rotation of the locking bolt by hand.

[0028] Reference Figure 2 In this embodiment, in order to limit the position of the main gear 200 in the horizontal direction to remain unchanged, a limiting portion 201 is provided on the upper surface and / or the lower surface of the main gear 200, and a guide portion 101 matching the limiting portion 201 is provided in the steering box 100. When the main gear 200 rotates, the limiting portion 201 rotates along the guide portion 101. The limiting portion 201 can be an annular boss or a roller arranged along an annular interval, and the guide portion 101 can be an annular groove matching the limiting portion 201. In this embodiment, the limiting portion 201 is an annular boss arranged on the lower surface of the main gear 200, and the guide portion 101 is an annular guide groove arranged on the inner bottom surface of the steering box 100. When the main gear 200 is installed in the steering box 100, the boss extends into the guide groove. When the main gear 200 rotates, the boss rotates along the guide groove.

[0029] Reference Figure 3 and Figure 1In this embodiment, the fixing seat 500 is an arc-shaped plate so as to fit the main rod and save space. Two connecting parts 102 for connecting the upper end of the fixing seat 500 are arranged on the side wall at the lower end of the first through hole, and the connecting part 102 is connected to the upper end of the fixing seat 500 by bolts. During installation, the left half box 120 is first fixedly connected to the fixing frame of the outboard motor through the fixing seat 500, and then the right half box 110 is assembled with the left half box 120, so that the main rod of the outboard motor is placed in the second through hole of the assembled main gear 200, and the left half box 120 is fixedly connected with the right half box 110 by tightening the locking bolt. Then the main rod connecting member 300 is clamped above the steering box 100, but the adjusting bolt is not completely tightened so that the main rod connecting member 300 can slide along the main rod. Slide the main rod connecting member 300 downwards to mesh the first tooth portion of the main rod connecting member 300 with the second tooth portion of the main gear 200, and finally tighten the adjusting bolt to tightly clamp the left clamping member 310 and the right clamping member 320 on the main rod, thereby achieving the connection between the main rod and the main gear 200. Figure 5 shown.

[0030] Reference Figure 5 The outboard motor of the embodiment of the utility model includes the above-mentioned external steering device. By connecting the rotation drive device 400 of the external steering device to the controller, the main rod can be controlled to rotate through the external steering device to realize the electric control of the ship's heading, which can free the user's hands and realize automatic navigation and electronic anchoring functions in conjunction with the corresponding control algorithm. The position of the external steering device on the main rod can be adjusted to suit the draft depth requirements of different ships, and it is easy to disassemble, replace, and repair and maintain.
