[0002] The electric outboard motors for small and medium-sized ships mainly include mounting frames and propellers. The propellers are fixed to the hull through the mounting frames, and the propellers can be swung on the mounting frames to meet the different needs of parking and sailing. When using the marine propeller, the propeller is placed underwater by adjusting the angle of the propeller, and the propeller rotates to generate propulsion force, thereby pushing the ship forward. During the ship's forward movement, the user can change the propulsion force and direction of the propeller through the control device, thereby driving the ship. When the ship is docked, the propeller is lifted so that the propeller is above the water surface to protect the propeller and the propeller power main shaft. Due to the heavy weight of the propeller, the electric outboard motors currently on the market are equipped with a paddle to lock the propeller in the lifted state (lifted off the water surface), and this paddle structure does not have a self-locking function.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] A propeller installation device for an electric outboard motor comprises: a base 1, a bracket 3, a retaining member 4, an anti-falling assembly 5 and a gear adjustment mechanism 6, wherein the bracket 3 is used to install the propeller on a hull, the base 1 is used to install a power main shaft 2 of the propeller, the base 1 is rotatably installed on the bracket 3 via a rotating shaft 7, the inclination angle of the power main shaft 2 with respect to the vertical plane is changed by swinging the base 1 relative to the bracket 3, thereby changing the relationship between the propeller at the bottom of the power main shaft 2 and the water surface; a locking groove 3-1 for locking the base 1 in a lifted state and a locking rod 3-2 for locking the base 1 in a submerged state are provided in the bracket 3, the opening of the locking groove 3-1 faces upward, the retaining member 4 is slidably installed on the base 1, and the retaining member 4 is adapted to the locking rod 3-2, that is, when the retaining member 4 and the locking rod 3-2 are in contact, the base 1 and the bracket are in a locked state. 3 is in a locked state, and the bottom of the power spindle 2 is in a submerged state. When the locking piece 4 and the locking rod 3-2 are separated, the base 1 and the bracket 3 are in a separated state, and the base 1 can be swung as needed; the anti-fall component 5 is swingably mounted on the base 1, and a locking rod 5-1 is provided on the anti-fall component 5, and the locking rod 5-1 is adapted to the locking groove 3-1, that is, when the locking rod 5-1 is engaged in the locking groove 3-1, the base 1 is locked in the lifted state of the power spindle 2. At this time, the bottom of the power spindle 2 is separated from the water surface. When the locking rod 5-1 and the locking groove 3-1 are separated, the base 1 can be put down so that the power spindle 2 extends underwater, and the anti-fall component 5 is driven to swing to drive the locking rod 5-1 to swing relative to the base 1, thereby realizing the engagement or separation of the locking rod 5-1 and the locking groove 3-1.

[0026] In this embodiment, when the power main shaft 2 is located in the water, since the water has a certain damping effect on the power main shaft 2 and the propeller, and the inclination angle of the power main shaft 2 with the vertical plane is small, in this state, even if the locking member 4 is accidentally touched, the falling impact force generated by the power main shaft 2 is small, and the angle of the base 1 is adjusted by the cooperation of the locking member 4 and the locking rod 3-2; when the power main shaft 2 is located above the water surface, the power main shaft 2 and the propeller are in a suspended state, and the falling impact force of the power main shaft 2 is large, and the base 1 is supported by the cooperation of the locking rod 5-1 and the locking groove 3-1. Since the locking rod 5-1 and the locking groove 3-1 are wrapped around the inner side of the bracket 3, and the opening of the locking groove 3-1 faces upward, which is opposite to the gravity direction of the base 1, the separation of the locking rod 5-1 and the locking groove 3-1 must be assisted by external force, thereby preventing the separation of the locking rod 5-1 and the locking groove 3-1 caused by accidental touching.

[0027] The bracket 3 includes two frame plates 3-6 symmetrically arranged about the middle of the bracket 3. Adjacent frame plates 3-6 are connected by a plurality of connecting bolts 3-7. A groove for connecting the frame plate 3-6 to the hull is provided on the frame plate 3-6. A locking bolt 3-8 is provided on the frame plate 3-6. The end of the locking bolt 3-8 extends into the groove and abuts against the hull, thereby fixing the frame plate 3-6 to the hull. An axial hole 3-9 is provided in the middle of the frame plate 3-6. Both ends of the rotating shaft 7 are respectively connected to the axial holes 3-9 of the two frame plates 3-6, so that the base 1 can be swingably installed between the adjacent frame plates 3-6. A plurality of angle adjustment holes 3-12 are provided on one side of the frame plate 3-6. The angle adjustment holes 3-12 are distributed with the shaft hole 3-9 as the center. The locking rod 3-2 is detachably connected to the angle adjustment hole 3-12. In the present embodiment, the moving direction of the locking member 4 is parallel to the axial direction of the power main shaft 2, and the locking member 4 cannot swing relative to the base 1. When the locking rod 3-2 is connected to the angle adjustment holes 3-12 at different positions, the locking member 4 is engaged with the locking rod 3-2 at the corresponding position. At this time, the angle of the base 1 relative to the bracket 3 will change with the different positions of the locking member 4 and the locking rod 3-2 engaged therewith. Thus, the angle between the base 1 and the bracket 3 can be adjusted by the cooperation of the locking member 4 and the locking rod 3-2, thereby changing the water entry depth of the power main shaft 2. When the locking piece 4 on the base 1 is locked with the locking rod 3-2 on the bracket 3, the bottom of the power main shaft 2 is located below the water surface, and the adjustable locking rod 3-2 is connected to different angle adjustment holes 3-12, which is used to change the depth of the power main shaft 2 extending below the water surface in the locked state, thereby changing the thrust generated by the propeller when the electric outboard motor is working.

[0028] An empty groove 3-10 for the sliding of the locking rod 5-1 is provided on the inner side wall of the frame plate 3-6, and a supporting rib 3-5 is provided in the empty groove 3-10. The locking groove 3-1 is formed in the middle of the supporting rib 3-5, and there is a certain distance between the bottom of the locking groove 3-1 and the top of the guide surface 3-4, so that a locking step 3-3 is formed on one side of the locking groove 3-1 to ensure that the locking rod 5-1 can be stably clamped in the locking groove 3-1, and an arc-shaped guide surface 3-4 is formed on one side of the supporting rib 3-5. A clamping guide surface 3-11 is also provided on the supporting rib 3-5. The clamping guide surface 3-11 is arranged on the side of the locking groove 3-1 away from the guide surface 3-4. The locking rod 5-1 is inserted in The locking rod 5-1 is in the empty slot 3-10, and the inner wall of the empty slot 3-10, the guide surface 3-4, and the engaging guide surface 3-11 guide the movement of the end of the locking rod 5-1; in the process of locking the power main shaft 2 in a lifted state and separated from the water surface by the locking rod 5-1, the movement process of the locking rod 5-1 is as follows: the locking rod 5-1 swings from the bottom of the empty slot 3-10 to the guide surface 3-4, and then is guided by the guide surface 3-4 to the top of the locking step 3-3, and then moves from the top of the locking step 3-3 to the engaging guide surface 3-11, and then falls into the locking slot 3-1 by the engaging guide surface 3-11, thereby locking the power main shaft 2 in a lifted state and separated from the water surface.

[0029] An installation cavity 1-1 is provided in the base 1, and the anti-fall component 5 can be swingably installed in the installation cavity 1-1. The anti-fall component 5 includes a swing connecting rod 5-2, and one end of the swing connecting rod 5-2 can be rotatably installed in the installation cavity 1-1. The locking rod 5-1 is arranged at the other end of the swing connecting rod 5-2. When the power spindle 2 is lifted, the base 1 rotates relative to the bracket 3 along with the power spindle 2, so that the distance between the lower end of the base 1 and the lower end of the bracket 3 increases, and by applying external force to the swing connecting rod 5-2 (the external force is provided by the torsion spring 5-4 or the driving handle 5-3 described below), the swing connecting rod 5-2 drives the locking rod 5-1 to swing relatively in the empty slot 3-10, so that the locking rod 5-1 is successively abutted against the locking slot 3-1 under the guidance of the inner wall of the empty slot 3-10, the guide surface 3-4 and the clamping guide surface 3-11.

[0030] In order to facilitate the operation and control of the swing connecting rod 5-2 in the installation cavity 1-1, a driving handle 5-3 is connected to the middle part of the swing connecting rod 5-2. The driving handle 5-3 is a bent rod, and the driving handle 5-3 extends out of the installation cavity 1-1, so that the driving handle 5-3 can apply a swinging force to the swing connecting rod 5-2; it should be noted that the driving handle 5-3 should extend above the base 1, so that the swing connecting rod 5-2 can be driven to swing through the driving handle.

[0031] A torsion spring 5-4 is provided at the connection between the swing connecting rod 5-2 and the base 1, and the torsion spring 5-4 is respectively abutted against the inner wall of the installation cavity 1-1 and the side wall of the swing connecting rod 5-2, and is used to apply a torsion force toward the guide surface 3-4 to the swing connecting rod 5-2. The locking rod 5-1 is abutted against the inner wall of the bracket 3 through the torsion spring 5-4. When the power spindle 2 is lifted upward, the locking rod 5-1 on the swing connecting rod 5-2 is abutted against the inner wall of the empty groove 3-10, the guide surface 3-4 and the locking guide surface 3-11 in turn, so that when the power spindle 2 is lowered, the locking rod 5-1 is locked in the stove locking groove 3-1. When it is necessary to separate the locking rod 5-1 from the locking groove 3-1, first lift the power spindle 2, and swing the operating base 1 relative to the bracket 3 so that the locking rod 5-1 abuts against the locking guide surface 3-11, and then use the driving handle 5-3 to apply an external force opposite to the force of the torsion spring 5-4 to the swing connecting rod 5-2, so that the locking rod 5-1 and the locking guide surface 3-11 are separated, and then the power spindle 2 is lowered. At this time, the external force on the driving handle 5-3 continues to act on the swing connecting rod 5-2. After the power spindle 2 is lowered, the external force on the driving handle 5-3 is removed, so that the locking rod 5-1 moves along the guide surface 3-4 to the empty groove 3-10.

[0032] The locking member 4 includes a locking insert 4-1 and a guide block 4-3. The locking insert 4-1 is slidably installed on the base 1 through the guide block 4-3. The sliding direction of the locking insert 4-1 is parallel to the axial direction of the power spindle 2. A locking groove 4-2 is provided at the bottom of the locking insert 4-1. The locking groove 4-2 is adapted to the locking rod 3-2, that is, when the locking insert 4-1 moves toward the locking rod 3-2, the locking rod 3-2 abuts against the locking groove 4-2. At this time, the base 1 and the bracket 3 are locked with each other. When the locking insert 4-1 moves away from the locking rod 3-2, the locking rod 3-2 and the locking groove 4-2 are separated. At this time, the base 1 can rotate relative to the bracket 3.

[0033] In this embodiment, a groove 1-2 adapted to the locking rod 3-2 is provided on the side wall of the base 1, and the locking groove 4-2 is open on the side close to the groove 1-2. When the locking groove 4-2 is inserted into the locking rod 3-2, a force toward the groove 1-2 is generated on the locking rod 3-2, so that the locking rod 3-2 moves into the groove 1-2, so that the inner wall of the locking groove 4-2 and the inner wall of the groove 1-2 abut against the circumferential side wall of the locking rod 3-2, ensuring that the base 1 and the locking rod 3-2 are tightly connected, thereby preventing shaking during the use of the electric outboard motor and improving the stability of the electric outboard motor.

[0034] The guide block 4-3 includes a guide base 4-4 and a guide end cover 4-5 which are assembled with each other, and a guide groove is formed between the guide base 4-4 and the guide end cover 4-5. The guide block 4-3 is fixed to the base 1 by a fixing screw 4-6, that is, the fixing screw 4-6 penetrates the guide base 4-4, the guide groove and the guide end cover 4-5 and is fixedly connected to the base 1. A travel groove 4-7 is provided on the positioning plug 4-1, and the travel groove 4-7 is located in the guide groove and is sleeved outside the fixing screw 4-6. The travel stroke of the positioning plug 4-1 is limited by the cooperation of the travel groove 4-7 and the fixing screw 4-6 to prevent the positioning slot 4-2 and the locking rod 3-2 from being misaligned due to the excessive movement stroke of the positioning plug 4-1, thereby ensuring the stability of the positioning member 4.

[0035] The gear adjustment mechanism 6 includes a main shaft limit ring 6-1 and a gear shift paddle 6-2. The main shaft limit ring 6-1 is fixedly sleeved on the outside of the power main shaft 2 and rotates with the power main shaft 2. The gear shift paddle 6-2 is slidably installed in the base 1, and the gear shift paddle 6-2 at least partially extends out of the base 1 to facilitate the shifting of the gear shift paddle 6-2. A plurality of rotation grooves 6-3 of different widths are provided on the main shaft limit ring 6-1, and a limit column 6-6 is provided on the gear shift paddle 6-2. The limit column 6-6 is adapted to the rotation groove 6-3, that is, the rotation angle of the power main shaft 2 is changed by connecting the limit column 6-6 with the rotation grooves 6-3 of different widths. In this embodiment, a first rotation groove 6-4 and a second rotation groove 6-5 are provided on the spindle limit ring 6-1. By toggling the gear paddle 6-2, the limit column 6-6 is switched among three states: connected to the first rotation groove 6-4, connected to the second rotation groove 6-5, and separated from the spindle limit ring 6-1. When the limit column 6-6 is connected to the first rotation groove 6-4, the rotation angle of the power spindle 2 is 0°. When the limit column 6-6 is connected to the second rotation groove 6-5, the rotation angle of the power spindle 2 is 150°. When the limit column 6-6 is separated from the spindle limit ring 6-1, the rotation angle of the power spindle 2 is 360°.
