[0019] Example

[0020] like Figure 1 As shown, a hydraulic steering system structure for an electric outboard motor comprises a fixed frame seat 1, wherein the fixed frame seat 1 is connected to an underwater housing, a lifting horizontal rotating shaft 2 is penetrated above the fixed frame seat 1, a lifting connecting seat 3 is movably connected to the lifting horizontal rotating shaft 2, a lifting rocker arm support 4 which is lifted synchronously with the lifting rocker arm support 3 is connected above the lifting connecting seat 3, a lifting rotating shaft plate 5 is connected below the lifting rocker arm support 4, a lifting steering shaft 6 is connected between the lifting rotating shaft plates 5, and the lifting steering shaft 6 is connected to one end of a lifting steering arm 7, and the fixed frame seat 1 is externally connected to the fixed frame seat 1. The left side and the outer right side are respectively connected to the first fixed bracket 8 and the second fixed bracket 9, a piston rod 10 is connected between the first fixed bracket 8 and the second fixed bracket 9, the piston rod 10 is connected to the inner cavity of the cylinder 11 and when the cylinder is filled with oil, the cylinder moves along the piston rod, the cylinder 11 is connected to a connecting ear plate 12, the connecting ear plate 12 is connected to one end of the first connecting arm 13 through a rotating shaft, the other end of the first connecting arm 13 is connected to one end of the second connecting arm 14 through a rotating shaft, and the other end of the second connecting arm 14 is connected to the other end of the lifting and steering arm 7.

[0021] In the present invention, the other end of the second connecting arm 14 is connected to the other end of the lifting and steering arm 7 via a movable shaft.

[0022] In the present invention, the first fixing bracket 8 and the second fixing bracket 9 are connected to the ends of the warping horizontal shaft 2 through nuts, wherein the first fixing bracket 8 and the second fixing bracket 9 are both arranged in a stepped structure.

[0023] The oil cylinder 11 described in the utility model is connected with the oil delivery device through a reversing valve, a throttle valve and an overflow valve, wherein the reversing valve changes the direction of the hydraulic oil, the throttle valve controls the size of the hydraulic oil, and the overflow valve controls the pressure of the hydraulic oil.

[0024] In the utility model, the rotation angle of the outboard motor is controlled by controlling the displacement of the oil cylinder, which is a technology known to those skilled in the art.

[0025] The working principle of the utility model is as follows:

[0026] During specific operation, the inner cavity of the cylinder is connected to the piston. When oil enters the left cavity of the cylinder, the cylinder moves to the right end along the piston rod, driving the connecting ear plate to move to the right, thereby driving the first connecting arm, the second connecting arm and the tilting steering arm to move and rotate to the right, so that the tilting steering shaft also rotates to the right; conversely, the direction of the oil circuit is changed by the reversing valve, and oil enters from the right cavity of the cylinder, and the cylinder moves to the left end along the piston rod, thereby moving the tilting steering shaft to the left, and pushing the outboard motor to turn left and right through the first connecting arm, the second connecting arm and the tilting steering arm.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
