Description

Technical Field

[0001] This application relates to the technical field of ship shifting, and particularly to a marine electric shifting mechanism. Background Art

[0002] A ship shifting mechanism is a mechanical device used to achieve variable speed control of a ship's propeller (such as a propeller). According to the navigation requirements, the driver issues a shifting command by operating a control device (such as a shifting lever or an electronic button). After receiving the command, the shifting mechanism adjusts the rotational speed and power output of the propeller through a series of actions to achieve functions such as accelerating, decelerating, stopping, and reversing the ship.

[0003] The existing technologies mainly adopt mechanical shifting or hydraulic shifting.

[0004] A mechanical shifting mechanism is a traditional shifting method, mainly achieving variable speed control through components such as mechanical linkages, gears, and synchronizers. Its disadvantages are complex operation, requiring manual operation by the driver, being complex and error-prone, and in addition, there may be relatively large impacts and noises during the shifting process.

[0005] A hydraulic shifting mechanism utilizes the principle of hydraulic transmission to achieve variable speed control through components such as hydraulic cylinders and hydraulic valves. Its disadvantages are that the hydraulic system is complex, the maintenance cost is high and professional technical support is required, and in addition, the shifting mechanism also has relatively high requirements for the quality and cleanliness of the hydraulic oil.

[0076] The following further explains and illustrates the present application in combination with specific implementation manners.

[0077] As Figure 1-2 shown, a marine electric shift mechanism provided in this embodiment includes an electric push rod 1;

[0078] The electric push rod 1 includes a fixed end 13 and a moving end 14;

[0079] On both sides of the electric push rod 1, a shift cable 2 and an electronic ruler displacement measuring instrument 3 are respectively arranged in parallel;

[0080] A T-shaped structure connector 4 is directly or indirectly arranged on the moving end of the electric push rod 1;

[0081] The T-shaped protruding end of the connector 4 is directly or indirectly connected to the moving end 14 of the electric push rod 1, and both ends of the T-shaped side surface of the connector 4 are directly or indirectly connected to the pulling end of the shift cable 2 and the measuring end of the electronic ruler displacement measuring instrument 3 respectively.

[0082] When the marine electric shift mechanism of the present application is working, by controlling the movement of the electric push rod 1, the shift cable 2 and the measuring end of the electronic ruler displacement measuring instrument 3 which are commonly connected with the connector 4 are driven to move. After the shift cable 2 moves, it will control the shift of the stern engine 21 to realize the shift operation, and the electronic ruler displacement measuring instrument 3 is used to measure the movement distance of the electric push rod 1 and the shift cable 2.

[0083] As Figure 1-5 shown, in a further implementation manner of the present application, the moving end 14 of the electric push rod 1 is indirectly connected to the connector 4 through an elastic part;

[0084] The elastic part includes a stepped screw 5, a first elastic part 6, a second elastic part 7 and a push-pull arm 8;

[0085] The push-pull arm 8 includes a vertical arm 40 and a connecting plate 41 which are integrally arranged;

[0086] The connecting plate 41 is fixedly connected to the moving end 14 of the electric push rod 1 and can be driven by the moving end 14 of the electric push rod 1 to move horizontally;

[0087] A perforation is arranged on the vertical arm 40, and a stepped screw 5 is arranged through it;

[0088] The middle part of the stepped screw 5 is arranged through the vertical arm 40, the side away from the electric push rod 1 is arranged through the connector 4, and a vertical plate 11 is arranged on the side close to the electric push rod 1;

[0089] A first elastic part 6 is arranged between the vertical arm 40 and the vertical plate 11;

[0090] A second elastic part 7 is arranged between the vertical arm 40 and the connector 4.

[0091] A slider 15 is fixedly arranged at the lower part of the connector 4;

[0092] The slider 15 is matched with the guide rail 12, so that the connector 4 moves along the guide rail 12 under the constraint of guiding and limiting.

[0093] When the marine electric shift mechanism of the present application is working, when the moving end 14 of the electric push rod 1 drives the push-pull arm 8 to move horizontally away from the electric push rod 1, the vertical arm 40 of the push-pull arm 8 pushes the second elastic part 7 and the second elastic part 7 pushes the connector 4 to move. When the moving end 14 of the electric push rod 1 drives the push-pull arm 8 to move horizontally towards the electric push rod 1, the vertical arm 40 of the push-pull arm 8 pushes the first elastic part 6 and the first elastic part 6 pushes the vertical plate 11 at one end of the stepped screw rod 5, so that the stepped screw rod 5 drives the connector 4 to move. When the electric push rod 1 is pushed to 53 - 56 mm, shifting is achieved (i.e., pushed to the farthest distance). In order to eliminate the hard error when the electric push rod 1 is pushed to the farthest distance during shifting, the present application sets the first elastic part 6 and the second elastic part 7 so that the control error is offset, improving the fault tolerance of the system and avoiding the risk of the shift cable being broken due to the push rod stroke error.

[0094] The sliding part 16 is matched with the push rod section 13 of the guide rail 12, so that the electric push rod 1 moves along the guide rail 12 under the constraint of guiding and limiting.

[0095] When the marine electric shift mechanism of the present application is working, when the gear is advanced from neutral to forward gear, the sliding part 16 on the electric push rod 1 is matched with the push rod section 13 of the guide rail 12, so that the electric push rod 1 is pushed forward. The movement of the electric push rod 1 drives the connector 4 and the slider 15 fixedly arranged at its lower part to slide along the connecting section 14 of the guide rail 12. When the connector 4 moves, it drives the shift cable 2 to move, thereby realizing the shifting of the stern engine 21. At the same time, when the front end of the electronic ruler displacement measuring instrument 3 is driven by the connector 4 to move, the electronic ruler displacement measuring instrument 3 can measure the moving distance and display and feedback it.

[0096] As Figure 1-2 shown in the further embodiment of the present application, the electronic ruler displacement measuring instrument 3 and the connector 4 are indirectly connected through the electronic ruler fixing sheet metal 17;

[0097] The fixed sheet metal 17 of the electronic ruler is L-shaped, one side is fixedly connected to the connector 4, and the other side is provided with fixing holes;

[0098] The measuring rod at the front end of the electronic ruler displacement measuring instrument 3 passes through the fixing holes;

[0099] A ferrule is sleeved at one end of the measuring rod away from the electronic ruler displacement measuring instrument 3 after passing through the fixing holes;

[0100] The ferrule abuts against the fixed sheet metal 17 of the electronic ruler.

[0101] As Figure 1 shown in the further embodiment of the present application, it further includes a bottom case 18;

[0102] The guide rail 12 and the electronic ruler displacement measuring instrument 3 are fixedly arranged in the bottom case 18;

[0103] A stopper 19 is also fixedly arranged on the inner side wall of the bottom case 18;

[0104] The shift cable 2 passes through the stopper 19;

[0105] The stopper 19 provides a guiding and limiting function for the shift cable 2;

[0106] The bottom case 18 is also provided with mounting fixing feet 20, which are provided with fixing holes for fixedly connecting the bottom case 18 and external components through fasteners.

[0107] As Figure 2 shown in the further embodiment of the present application, a hoop 39 is arranged on the bottom case 18, and the hoop 39 surrounds the electric push rod 1 and makes the electric push rod 1 tightly connected to the bottom case 18;

[0108] The marine electric shift mechanism of the present application includes a shift box (such as Figure 2 ) and a stern engine (such as Figure 5 ). The shift box is a control unit, and the stern engine is a working unit. The shift box and the stern engine are controlled and connected through the shift cable 2.

[0109] As Figure 6 shown in the further embodiment of the present application, the stern engine 21 further includes a transmission shaft box 22 and a gear box 23;

[0110] The gear box 23 is arranged below the transmission shaft box 22;

[0111] A universal coupling shaft 38 and the shift hole 24 are arranged on the transmission shaft box 22;

[0112] One end of the shift cable 2 away from the connector 4 is arranged on the shift hole 24 of the stern engine 21.

[0113] As Figure 7 Shown in the further embodiment of the present application, a clamping portion 25 is arranged at one end of the shift cable 2 connected to the shift hole 24;

[0114] The clamping portion 25 is a cylinder with a diameter larger than that of the shift cable 2;

[0115] A shift link 26 is arranged in the shift hole 24;

[0116] One end of the shift link 26 close to the shift cable 2 is provided with a chuck 27;

[0117] The chuck 27 connects the shift cable 2 and the shift link 26 by clamping the clamping portion 25.

[0118] As Figure 7-8 Shown in the further embodiment of the present application, the chuck 27 includes a base 28 and a chuck cover 29;

[0119] The base 28 and the shift link 26 are of an integral structure;

[0120] One ends of the base 28 and the chuck cover 29 away from the shift cable 2 are connected by a connecting shaft 30;

[0121] A cavity 31 is arranged on the base 28 for accommodating the clamping portion 25;

[0122] After the clamping portion 25 enters the cavity 31, the chuck cover 29 is covered downwards, and the positioning convex block 32 arranged on the chuck cover 29 enters the positioning groove 33 arranged on the base 28. The chuck cover 29 and the base 28 clamp and limit the clamping portion 25 to prevent the shift cable 2 from leaving the chuck 27.

[0123] As Figure 8-9 Shown in the further embodiment of the present application, the cavity 31 includes a chuck head accommodating area 34 and a wire body accommodating area 35;

[0124] The width of the chuck head accommodating area 34 is equal to the diameter of the clamping portion 25;

[0125] The wire body accommodating area 35 is arranged on a concave plate 36 at one end of the base 28 away from the connecting shaft 30;

[0126] After the clamping portion 25 enters the cavity 31, the clamping portion 25 is arranged in the chuck head accommodating area 34, and the shift cable 2 passes through the wire body accommodating area 35;

[0127] The lower half of the clamping part 25 close to one side of the concave plate 36 abuts against the concave plate 36;

[0128] A retaining beam 37 is provided on one side of the clamping cover 29 away from the connecting shaft 30;

[0129] When the clamping cover 29 and the base 28 are closed, the retaining beam 37 abuts against the upper half of the clamping part 25 close to one side of the concave plate 36, so as to cooperate with the concave plate 36 to limit the clamping part 25.

[0130] When a marine electric shift mechanism of the present application is working, the shift wire 2 is connected to a shift hole 24 on the stern engine 21. Specifically, a shift link 26 that can be pulled out and pushed back is arranged in the shift hole 24, and a chuck 27 for connecting with the shift wire 2 is arranged at the end of the shift link 26. After the chuck 27 is opened, the clamping part 25 at the end of the shift wire 2 is placed into the cavity 31, the chuck 27 is closed and the shift link 26 is pushed back into the stern engine 21, and the shift connection between the shift wire 2 and the stern engine 21 is completed.

[0131] Adopting the above technical solution, the present application has the following beneficial effects:

[0132] (1) By introducing the electronic ruler displacement measuring instrument 3, the movement distances of the electric push rod 1 and the shift wire 2 are measured in real time, and displayed and fed back, significantly improving the accuracy and stability of the shift operation.

[0133] (2) An elastic part (including a stepped screw 5, a first elastic part 6, a second elastic part 7 and a push-pull arm 8) is arranged between the electric push rod 1 and the connector 4, effectively eliminating the hard error when the electric push rod 1 is pushed to the farthest distance during shifting, and improving the fault tolerance and adaptability of the system.

[0134] (3) The guide rail 12 is used to guide and limit the connector 4, ensuring the stability and consistency of the shift mechanism during the movement process.

[0135] (4) All key components are integrated in the bottom shell 18, improving the overall integration degree of the equipment and making the appearance more neat and beautiful. At the same time, the design of the mounting and fixing feet 20 on the bottom shell 18 enables the entire shift mechanism to be conveniently fixed in the ship's cab, improving the space utilization rate.

[0136] (5) Through the design of the clamping part 25 and the chuck 27, the connection between the shift wire 2 and the shift system of the stern engine 21 becomes more stable. The cylindrical structure of the clamping part 25 cooperates with the clamping mechanism of the chuck 27, effectively preventing the shift wire 2 from loosening or falling off during the shifting process, thereby improving the reliability and safety of the shift operation.

[0137] (6) The convenience of the design of the chuck 27 makes the connection process of the shift cable 2 simpler and faster. Just put the clamping part 25 into the cavity 31 of the chuck 27 and close the chuck 27 to complete the connection, which greatly improves the work efficiency and operation convenience.

[0138] (7) The design that the cavity 31 is divided into a chuck area 34 and a cable body area 35 not only ensures the firm clamping of the clamping part 25 but also facilitates the smooth passage of the shift cable 2. This design enables the shift mechanism to adapt to shift cables 2 of different sizes and types, enhancing the versatility and adaptability of the system.

[0139] (8) The integrated structure design of the chuck 27 and the shift link 26 and the precise cooperation of the clamping mechanism reduce the wear and looseness caused by long-term use and vibration. This helps to extend the service life of the shift system and improve the overall stability and durability.
