[0002] The outboard motors for small and medium-sized ships such as speedboats and rubber boats mainly include a main engine, a control device and a power source. The main engine includes a gear shifting device and a propeller. When using the propeller, the main engine is fixed to the ship through the gear shifting device. The propeller of the propeller is located underwater, and the propeller rotates to generate a propulsive force to push the ship forward. When the propeller stops working, it is necessary to control the propeller to lift through the gear shifting device so that the propeller leaves the water surface at a certain angle and maintains the water attitude.

[0003] However, when the propeller in the prior art is in the water attitude, it is easy to accidentally fall due to misoperation or accidental touch by the staff, and then the propeller accidentally changes from the water attitude to the underwater attitude, or the propeller is damaged.

[0028] The following will further describe the present utility model in detail according to the drawings and embodiments.

[0029] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0030] Refer to Figures 1 to 7, what is disclosed in the embodiments of the present utility model is: a marine outboard motor, including a set of clamping bases 1. A rotating mounting seat 110 is rotatably arranged between the set of clamping bases 1. The rotating mounting seat 110 is used for mounting a propeller. A gear position clamping frame 111 is arranged between the rotating mounting seat 110 and the clamping base 1. One end of the gear position clamping frame 111 is hinged to the bottom of the rotating mounting seat 110, and the other end is movably arranged between the set of clamping bases 1. Specifically, a clamping rod 2 is arranged at the other end of the gear position clamping frame 111. The clamping rod 2 is movably (slidably) arranged between the set of clamping bases 1. By adjusting the gear position clamping frame 111, the clamping rod 2 is moved to different positions of the clamping base 1, thereby adjusting the water attitude and underwater attitude of the propeller.

[0031] Specifically, in this embodiment, a water gear position part 101 and an underwater gear position part 102 are arranged on the clamping base 1. When the clamping rod 2 slides into the water gear position part 101, the propeller is in a water attitude. When the water clamping rod 2 slides into the underwater gear position part 102, the propeller is in an underwater attitude. In this embodiment, a locking mechanism is arranged at the inlet and outlet of the water gear position part 101 on the clamping base 1 to limit the clamping rod 2 from sliding out of the inlet and outlet of the water gear position part 101 when the propeller is in a water attitude, so as to prevent the propeller from accidentally falling due to misoperation or accidental touch by the staff, and further avoid damage to the propeller.

[0032] Among them, the locking mechanism includes: a locking channel 3, which is arranged on the clamping base 1 and located at the inlet and outlet of the water gear position part 101; a locking pin 4, which is slidably arranged in the locking channel 3. One end of the locking pin 4 can slide out of the locking channel 3 to be used for abutting against the side wall of the clamping rod 2 located in the water gear position part 101, thereby restricting the clamping rod 2 from sliding out of the inlet and outlet of the water gear position part 101. When the propeller is in a water attitude (i.e., when the clamping rod 2 is located in the water gear position part 101), one end of the locking pin 4 slides out of the water locking channel 3, and the side wall on its side close to the water gear position part 101 abuts against the side wall of the clamping rod 2, thereby restricting the clamping rod 2 from sliding out of the inlet and outlet of the water gear position part 101.

[0033] An elastic member 5 is arranged on the locking pin 4. The elastic member 5 is used for applying a force to the locking pin 4 to extend towards the inlet and outlet of the water gear position part 101 or to prevent it from extending into the locking channel 3. In this embodiment, the elastic member 5 is a compression spring. The compression spring is sleeved on the locking pin 4, and one end abuts against the side wall of the locking pin 4, and the other end abuts against the inner wall of the locking channel 3, thereby applying a force to the locking pin 4 to extend towards the inlet and outlet of the water gear position part 101 (such as Figure 3as shown, a force that moves from a to b (or prevents entry into the locking channel 3, e.g., Figure 3 as shown, a force that moves from b to a).

[0034] A first unlocking device is provided on the locking pin 4. The first unlocking device is used to drive the locking pin 4 to extend into the locking channel 3 when the clamping rod 2 slides into the water gear portion 101 (e.g., Figure 3 as shown, moving from b to a), so that the clamping rod 2 can slide into the water gear portion 101 from the inlet and outlet of the water gear portion 101; the first unlocking device includes an inclined guiding surface 6 provided at one end of the locking pin 4 located at the inlet and outlet of the water gear portion 101, and the inclined guiding surface 6 extends from the bottom of the locking pin 4 towards the side away from the water gear portion 101; when the thruster is controlled to change from an underwater posture to a water posture, the clamping rod 2 slides into the water gear portion 101 from the inlet and outlet of the water gear portion 101. During this process, the lower end of the clamping rod 2 first abuts against the inclined guiding surface 6 and applies a force to the clamping rod 2, so that the locking pin 4 extends into the locking channel 3 (at this time, the elastic member 5 is compressed by force), and finally the clamping rod 2 can cross over the locking pin 4 and enter the water gear portion 101. After the clamping rod 2 enters the water gear portion 101, the lower end of the clamping rod 2 no longer abuts against the locking pin 4. At this time, the locking pin 4 is reset by the elastic potential energy of the elastic member 5, and the side wall of the locking pin 4 close to the water gear portion 101 abuts against the side wall of the clamping rod 2, thereby restricting the clamping rod 2 from sliding out from the inlet and outlet of the water gear portion 101.

[0035] When it is necessary to control the thruster to switch from a water posture to an underwater posture; it is necessary to control the locking pin 4 to first extend into the locking channel 3 (e.g., Figure 3 as shown, moving from b to a). At this time, the clamping rod 2 can only then disengage from the water gear portion 101; therefore, in this embodiment, a second unlocking device is provided on the locking pin 4. The second unlocking device is used to control the locking pin 4 to extend into the locking channel 3 so that the clamping rod 2 can slide out from the water gear portion 101; specifically, the second unlocking device includes: the end of the locking pin 4 away from the inlet and outlet of the water gear portion 101 penetrates through the clamping base 1, and a control member 7 (pull ring) is provided on the end of the locking pin 4 away from the inlet and outlet of the water gear portion 101; the staff can pull the control member 7 (pull ring), thereby driving the locking pin 4 to extend into the locking channel 3 (specifically as Figure 3 shown, moving from b to a). At this time, the locking pin 4 no longer restricts the clamping rod 2, and the clamping rod 2 can then slide out from the water gear portion 101.

[0036] However, due to the above setting of the second unlocking device, when the staff pulls the control member 7, they also need to simultaneously control the rotation of the thruster (i.e., one hand controls the locking pin 4 and the other hand controls the rotation of the thruster), which is inconvenient to operate. Therefore, for the convenience of operation, a resisting protrusion 8 is provided on the side wall of the locking pin 4, and a limiting platform 9 is provided in the locking channel 3 to be used for, when the locking pin 4 slides to a predetermined position in the locking channel 3 and rotates a predetermined angle in a preset direction, the limiting platform 9 resists against the limiting platform 9 to limit the reset of the locking pin 4; specifically in use, the staff can first pull the control member 7 (pull ring), thereby driving the locking pin 4 to extend into the locking channel 3 by a predetermined distance. After that, rotate the control member 7 (pull ring) to drive the locking pin 4 to rotate a predetermined angle. At this time, the limiting platform 9 is aligned with the resisting protrusion 9. The staff then releases the control member 7 (pull ring). At this time, the limiting platform 9 abuts against the resisting protrusion 9, and the locking pin 4 will no longer be reset by the elastic potential energy of the compression spring. At this time, the locking pin 4 does not restrict the clamping rod 2 from sliding out from the water position portion 101, and the staff can control the rotation of the thruster, thereby realizing the transformation of the thruster from the water attitude to the underwater attitude; when the thruster is transformed into the underwater attitude, the staff then controls the control member 7 (pull ring) to rotate in the reverse direction, so that the limiting platform 9 and the resisting protrusion 9 no longer abut against each other, and the locking pin 4 can be reset under the elastic potential energy of the compression spring.

[0037] However, due to the above structure setting, after the water attitude is released, the staff needs to rotate the locking pin 4 again, so that the locking pin 4 is reset by the elastic potential energy of the compression spring. If the staff forgets to manually rotate and reset, then when entering the next water attitude, the limit of the locking pin 4 will no longer be triggered, and further the structural stability of the outboard motor in the water attitude cannot be guaranteed. Therefore, as a further improvement, a reset device is provided between the locking pin 4 and the clamping rod 2, and the reset device is used for, when the clamping rod 2 slides out from the water position portion 101, driving the locking pin 4 to rotate in the direction opposite to the preset direction, so that the limiting platform 9 and the resisting protrusion 9 no longer abut against each other, and the locking pin 4 can be reset under the elastic potential energy of the compression spring.

[0038] Specifically, the reset device includes a reset block 10 provided on the locking pin 4, and a reset groove 11 for the reset block 10 to pass through is provided at one end of the clamping rod 2 close to the locking pin 4. The reset groove 11 is used for, when the clamping rod 2 disengages from the water position portion 101, abutting against the reset block 10 to drive the locking pin 4 to rotate; for reference Figure 7, specifically when it is necessary to control the thruster to switch from the water attitude to the underwater attitude, the staff first pulls the control member 7 (pull ring), thereby driving the locking pin 4 to extend into the locking channel 3 by a predetermined distance. Then, the control member 7 (pull ring) is rotated to drive the locking pin 4 to rotate by a preset angle. At this time, the limiting platform 9 is aligned with the abutting protrusion 9. The staff then releases the control member 7 (pull ring). At this time, the limiting platform 9 abuts against the abutting protrusion 9, and the locking pin 4 will no longer be reset by the elastic potential energy of the compression spring. At this time, the locking pin 4 does not restrict the clamping rod 2 from sliding out from the water gear portion 101. At this time, the reset block 10 provided on the locking pin 4 is still located at the inlet and outlet of the water gear portion 101. When the clamping rod 2 slides out from the water gear portion 101, the side wall of the reset groove 11 will abut against the reset block 10 and apply a force to the reset block 10 during the continuous movement, thereby driving the locking pin 4 to rotate, and the rotation direction is opposite to the preset direction. Finally, the limiting platform 9 and the abutting protrusion 9 no longer abut against each other. After the clamping rod 2 is disengaged from the locking pin 4, the locking pin 4 can be reset under the elastic potential energy of the compression spring; the structure is simple, and there is no need for the staff to manually rotate and reset it.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
