At present, most outboard motors comprise a mounting frame, a power frame and a propeller. The mounting frame is installed on the ship body, the power frame is swingably installed on the mounting frame, and the propeller is fixed on the power frame. According to different use requirements, the propeller is inserted into or not inserted into water by swinging the power frame. In order to facilitate the swinging of the power frame, an electric push rod is arranged between the mounting frame and the power frame. The power frame and the propeller on the power frame are lifted by the electric push rod, so that the propeller is lifted above the water surface. However, the outboard motor has the following disadvantages. The propeller is supported by the electric push rod, but the weight of the propeller is large.

Detailed Implementation
[0024] The present invention will now be further described with reference to the accompanying drawings.
[0025] A support mechanism for an electric outboard motor is disclosed. The electric outboard motor includes a mounting frame 1 for connection to the hull and a power frame 2 for mounting the propeller. The power frame 2 is oscillatingly mounted on the mounting frame 1. By driving the power frame 2 to oscillate, the operating state of the propeller (i.e., whether the power component of the propeller is inserted into the water) is changed. To facilitate the separation of the propeller from the water, a push rod 3 is connected between the power frame 2 and the mounting frame 1. Preferably, the push rod 3 is an electric push rod or an electric cylinder, which drives the power frame 2 to oscillate relative to the mounting frame 1. In this embodiment, the mounting frame 1 is provided with a mounting groove 15 for mounting the power frame 2. The power frame 2 is oscillatingly mounted in the mounting groove 15 via a rotating shaft. The support mechanism includes a support plate 4, which is rotatably mounted on the power frame 2 or the mounting frame 1. At least one support plane 5 is provided on the mounting frame 1 or the power frame 2. When the power frame 2 is supported by the push rod 3, the support plate 4 abuts against the support plane 5. The support plate 4 and the support plane 5 work together to support the power frame 2 supported by the push rod 3. During use, a certain gap may exist between the support plate 4 and the support plane 5. When the push rod 3 fails, the support plate 4 and the support plane 5 abut against each other, thereby preventing further relative swaying of the power frame 2 and the mounting frame 1, thus preventing the power frame 2 or the propeller on the power frame 2 from colliding with the hull. It also prevents further relative swaying of the power frame 2 and the mounting frame 1 from causing injury to the operators.
[0026] In this embodiment, to ensure the ease of installation of the support plate 4, the support plate 4 is rotatably mounted on the side wall of the power frame 2, and the support plane 5 is arranged on the top surface of the mounting frame 1. The support plate 4 is L-shaped, which facilitates the installation of the support plate 4 on the power frame 2 and increases the contact area between the support plate 4 and the support plane 5, ensuring that the mounting frame 1 can stably abut against the support plane 5, thereby ensuring the stability of the support mechanism in use.
[0027] In order to prevent the bottom surface of the support plate 4 from moving on the support plane 5 when the support plate 4 and the support plane 5 abut, at least one limiting groove 14 for limiting the support plate 4 is arranged on the mounting frame 1, and in this embodiment, the number of the limiting groove 14 is one, and the bottom surface of the limiting groove 14 is the support plane 5.
[0028] In order to further ensure the stability of the support plate 4 when the support plate 4 and the support plane 5 abut, a limiting block 6 is arranged on the side wall of the power frame 2, the limiting block 6 is located on one side of the support plate 4, and the limiting block 6 is adapted to the support plane 5, that is, when the side wall of the support plate 4 abuts against the limiting block 6, the support plate 4 is arranged vertically to the support plane 5 under the limiting action of the limiting block 6, thereby preventing the support plate 4 from tilting when the support plate 4 and the support plane 5 abut.
[0029] During use of the support plate 4, the support plate 4 is prone to rotating under the action of a force away from the limiting block 6, which causes the support plate 4 to separate from the support plane 5 and leads to failure of the support plate 4. In order to prevent the support plate 4 from failing under the action of an external force, the support mechanism includes a support locking spring 7 for locking the support plate 4 in a support state, the support locking spring 7 is connected to the support plate 4, and as an optional implementation, one end of the support locking spring 7 is connected to the power frame 2, and the other end is connected to the support plate 4. The support locking spring 7 provides a force towards the limiting block 6 to the support plate 4, so as to abut the support plate 4 against the limiting block 6 and prevent the support plate 4 from failing under the action of an external force.
[0030] During swinging of the power frame 2 relative to the mounting frame 1, the support locking spring 7 is prone to interfering with the mounting frame 1, which causes the support locking spring 7 to fail and be damaged. In order to prevent the support locking spring 7 from failing, the support mechanism further includes a rotating shaft 8, the support plate 4 is swingably mounted on the power frame 2 through the rotating shaft 8, and the support plate 4 rotates simultaneously with the rotating shaft 8, the rotating shaft 8 extends into the power frame 2, the support locking spring 7 is arranged in the power frame 2 and connected to the rotating shaft 8 located in the power frame 2, so as to realize connection of the support locking spring 7 to the support plate 4 through the rotating shaft 8, and to exert a rotating force on the rotating shaft 8 through the support locking spring 7, so as to exert a force towards the limiting block 6 on the support plate 4, thereby abutting the support plate 4 against the limiting block 6.
[0031] Two rotating shafts 8 are installed on the power frame 2, and connecting seats 10 for connecting adjacent rotating shafts 8 are installed at the ends of the two rotating shafts 8, respectively. An installation gap 11 is arranged between adjacent connecting seats 10, an eccentric shaft 9 is fixed in the installation gap 11, and the axis of the eccentric shaft 9 is arranged in a staggered manner with the axis of the rotating shaft 8, so that the rotating shaft 8, the connecting seat 10, and the eccentric shaft 9 form a crankshaft structure, so as to provide a rotating force to the rotating shaft 8 through the eccentric shaft 9. One side end of the supporting locking spring 7 is connected with the eccentric shaft 9, and the rotating force is applied to the rotating shaft 8 through the supporting locking spring 7, and the other side end of the supporting locking spring 7 is fixed to the inner side of the power frame 2 through a spring mounting plate 16.
[0032] In order to completely lower the power frame 2 (the propeller on the power frame 2 extends into the water), it is necessary to fold the supporting plate 4. In order to fix and position the supporting plate 4 in the folded state (the supporting plate 4 and the supporting plane 5 are separated), a ball plunger 12 is arranged on the side wall of the power frame 2. When the supporting plate 4 is folded, the ball plunger 12 abuts against the inner side end face of the supporting plate 4, thereby locking the supporting plate 4.
[0033] A stop block 13 is arranged on the side wall of the power frame 2, and the stop block 13 is arranged on one side of the ball plunger 12. By positioning the supporting plate 4, when the side wall of the supporting plate 4 abuts against the side wall of the stop block 13, the circular face of the ball plunger 12 abuts against the inner side end face of the supporting plate 4, so that the friction between the ball plunger 12 and the supporting plate 4 increases, thereby locking the supporting plate 4. As an optional embodiment, a circular groove is arranged on the inner side end face of the supporting plate 4, and when the side wall of the supporting plate 4 abuts against the side wall of the stop block 13, the ball plunger 12 is clamped in the circular groove, thereby achieving the locking of the supporting plate 4.
[0034] In some preferred embodiments, when the supporting plate 4 abuts against the stop block 13, the axis of the rotating shaft 8, the axis of the eccentric shaft 9, and the axis of the supporting locking spring 7 are located in the same plane, that is, the force of the supporting locking spring 7 cannot drive the rotating shaft 8 to rotate. As another preferred embodiment, the axis of the eccentric shaft 9 is located below the plane in which the axis of the rotating shaft 8 and the axis of the supporting locking spring 7 are located, that is, under the action of the supporting locking spring 7, the supporting plate 4 swings towards the stop block 13, so that the supporting plate 4 abuts against the stop block 13, thereby achieving the locking of the supporting plate 4.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
