The shifting mechanism further includes a shifting shaft passing through the lower frame, the active sprocket, the intermediate frame, the active gear and the upper frame. The shifting shaft is provided with grooves matching with the inner protrusions of the active sprocket and the active gear.

[0014] A further improvement of the above technical solution of the present invention lies in that: a circular groove is arranged at the top of the insertion block. A pointer located between the handle rod and the housing and matching with the circular groove is arranged at the top of the insertion block, and a gear position mark matching with the pointer is arranged on the housing.

[0015] A further improvement of the technical solution of the present invention lies in that: the starting protection logic of the diesel outboard engine of the control mechanism includes detecting the starting speed of the diesel outboard engine, starting timing after the speed exceeds the starting speed requirement, and stopping starting if it fails to start within a certain time to achieve a protection effect; detecting the gear position state and prohibiting starting the diesel outboard engine in a non-neutral gear state.

[0017] Due to the adoption of the above technical solution, the technical progress achieved by the present invention includes:

[0018] The present invention can pull the shift cable to achieve the shift operation of the diesel outboard motor through the provided shift mechanism; the provided handle can drive the shift mechanism to complete the shift; the provided control mechanism can control the throttle opening of the diesel outboard motor according to the detection result of the angle sensor; the control mechanism can also protect the diesel outboard motor when it is started, so as to prevent the motor from being damaged by long-term abnormal operation when the diesel outboard motor is started or from being in a non-neutral state when it is started, thereby preventing the diesel outboard motor from being damaged; at the same time, the control mechanism can also complete the operations such as warming up and starting up of the diesel outboard motor with one key; the present invention integrates the functions of shifting, adjusting the throttle size, warming up, starting up, and starting protection of the diesel outboard motor, and each function can be completed on the present invention, thereby simplifying the structure and saving the installation space and simplifying the operation steps.

When the rotation angle of the active gear is zero, it means that the diesel outboard motor is in a neutral state, when the rotation angle of the active gear is greater than zero and less than a set value, it means that the diesel outboard motor is shifting, and when the rotation angle of the active gear is at the set value, it means that the diesel outboard motor has completed the shifting, and when the rotation angle of the active gear is greater than the set value, the control mechanism controls the throttle of the diesel outboard motor to open, and the larger the rotation angle, the larger the throttle opening.

[0021] The adjusting block provided in the present invention can adjust the clamping degree of the shift shaft, thereby adjusting the rotation tightness of the shift shaft.

[0032] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the detailed implementation manners and with reference to the accompanying drawings. In the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0033] First, refer to Figures 1 - 4It can be seen that the present invention includes a housing 1, a shift mechanism 2 is installed inside the housing 1, a handle grip 3 for driving the shift mechanism 2 is provided on one side of the housing 1, and an angle sensor 4 for detecting the rotation angle of the handle grip 3 is installed inside the shift mechanism 2. At the same time, the present invention further includes a control mechanism for controlling the throttle opening of the diesel outboard engine, capable of performing warm-up operation, trimming operation and starting protection through a preset program. When the present invention is in use, by rotating the handle grip 3, the shift operation of the diesel outboard engine can be realized. At the same time, when the diesel outboard engine is in the forward or reverse gear, the control mechanism can control the opening degree of the throttle according to the rotation angle of the handle grip 3. The larger the rotation angle, the larger the throttle opening degree. When the diesel outboard engine fails to start for a long time or has started but still receives a start instruction, the start is automatically stopped to protect the starting motor and the diesel outboard engine. Moreover, the control mechanism can also increase the water temperature of the diesel outboard engine by performing a warm-up operation. When the water temperature is higher than a certain value (such as -15° to -30°), the control mechanism no longer limits the maximum throttle opening value. At the same time, when the diesel outboard engine starts and is not in the neutral gear state, the control mechanism can prohibit the starting of the diesel outboard engine to prevent misoperation. The present invention can also perform a trimming operation through a set trimming program.

[0034] In the present invention, when the shift mechanism 2 is specifically arranged, it includes a lower frame 21, a middle frame and an upper frame 23 arranged side by side in sequence. The specific connection method between the lower frame 21 and the middle frame is that a connecting column with a threaded hole is fixedly connected to the side of the lower frame 21 facing the middle frame. A connecting hole is provided at the position of the middle frame corresponding to the connecting column. When the lower frame 21 is connected to the middle frame, the connecting column of the lower frame 21 is inserted into the connecting hole of the middle frame, and the end of the connecting column away from the lower frame 21 is flush with the side of the middle frame away from the lower frame 21. Then, a bolt is screwed into the threaded hole of the connecting column to connect the lower frame 21 and the middle frame together. At the same time, the connection method between the middle frame and the upper frame 23 in the present invention is the same as the connection method between the lower frame 21 and the middle frame.

[0035] Among them, an active sheave 24 that can rotate along its own axis is clamped between the lower frame 21 and the middle frame. An upper stop block 20 and a driven sheave 25 are respectively fitted to the top and bottom of the active sheave 24. The upper stop block 20 is fixedly sleeved on the connecting column located at the top of the active sheave 24. The driven sheave 25 is sleeved on the connecting column located at the bottom of the active sheave 24 and can rotate. At the same time, an outer groove 251 that cooperates with the outer protrusion 242 of the active sheave 24 is formed on the edge of the driven sheave 25, and the end of the driven sheave 25 is connected to the end of the shift cable. When the active sheave 24 rotates and the outer protrusion 242 of the active sheave 24 passes through the outer groove 251 of the driven sheave 25, the driven sheave 25 can be toggled to rotate. The rotating driven sheave 25 pulls the shift cable, thereby achieving the purpose of shifting gears; the upper stop block 20 can limit the rotation angle of the active sheave 24 to prevent the active sheave 24 from rotating continuously in one direction and damaging the present invention.

[0036] An active gear 26 that can rotate along its own axis is clamped between the middle frame and the upper frame 23. A driven gear 27 that meshes with the active gear 26 is provided at the bottom of the active gear 26. The driven gear 27 is sleeved on the connecting column located at the middle frame 22 and can rotate. At the same time, an angle sensor 4 for detecting the rotation angle of the active gear 26 is connected to the active gear 26. The angle sensor 4 can adopt a Hall sensor or a potentiometer commonly used in the prior art.

[0037] In order to drive the active sheave 24 and the active gear 26 to rotate in the present invention, the shift mechanism 2 further includes a shift shaft 28 that sequentially penetrates through the lower frame 21, the active sheave 24, the middle frame, the active gear 26, and the upper frame 23. Grooves are provided on the side wall of the shift shaft 28 corresponding to the inner protrusions 241 of the active sheave 24 and the inner protrusions 241 of the active gear 26. The grooves can be connected together in cooperation with the corresponding inner protrusions 241 of the active sheave 24 and the inner protrusions 241 of the active gear 26. When the shift shaft 28 rotates, it can drive the active sheave 24 and the active gear 26 to rotate simultaneously, thereby achieving the purpose of shifting gears.

[0038] At the same time, an adjusting block 29 for clamping the shift shaft 28 is also connected to the side of the upper frame 23 away from the middle frame by bolts. By adjusting the tightness of the adjusting block 29, the clamping degree of the shift shaft 28 can be adjusted, thereby adjusting the rotation tightness of the shift shaft 28.

[0039] In the present invention, the handle grip 3, when specifically arranged, includes a handle rod 31. One side of the handle rod 31 is connected to a handle inner cover 32 by bolts. At the same time, one end of the handle rod 31 is connected to a handle grip 33 perpendicular to the handle rod 31. The other end of the handle rod 31 is connected to the shifting mechanism 2. When the handle rod 31 is specifically connected to the shifting mechanism 2, a plug 34 is fixedly connected to the end of the handle rod 31, and a slot 281 through hole matching the plug 34 is formed along the length direction of the shifting shaft 28 of the shifting mechanism 2. When the handle grip 3 is connected to the shifting mechanism 2, the plug 34 on the handle rod 31 can be inserted into the slot 281 of the shifting shaft 28 and fixed together by bolts.

[0040] In the present invention, in order to conveniently obtain the current gear state of the diesel outboard engine according to the position of the handle grip 3, a pointer 36 is arranged between the handle grip 3 and the shifting mechanism 2. Specifically, a circular groove 35 matching the pointer 36 is formed at the top of the plug 34, and the pointer 36 is located in the circular groove 35 and fixed to the handle rod 31 by bolts.

[0041] In the present invention, the housing 1, when specifically arranged, includes an upper cover 11 and a lower cover 12 located below the upper cover 11. A side opening and a bottom opening are respectively formed on one side and the bottom of the lower cover 12; the housing 1 further includes a side plate 13 for closing the side opening; at the same time, gear position markings (F, N, R) matching the pointer 36 are engraved on the outer wall of the upper cover 11. When the present invention is installed, first, the shifting mechanism 2 is connected to the shifting cable, then the shifting mechanism 2 is installed in the upper cover 11, then the lower cover 12 and the upper cover 11 are connected together, and finally the side plate 13 is installed on the lower cover 12. At this time, the head of the shifting cable just closes the bottom opening of the lower cover 12, thereby completely enclosing the housing 1 to prevent water ingress. At the same time, the upper cover 11, the lower cover 12 and the side plate 13 should all be made of waterproof and wear-resistant materials (such as plastics, polyester fibers, etc.) in the prior art. In order to conveniently connect the handle grip 3 to the shifting mechanism 2, circular holes 14 are formed on the left and right side walls of the upper shell. When the shifting mechanism 2 is installed in the upper cover 11, both ends of the shifting shaft 28 penetrate through the two circular holes 14 and protrude, so as to conveniently connect the handle grip 3 to the shifting mechanism 2. When the handle grip 3 is connected to the shifting mechanism 2, the pointer 36 is located between the handle rod 31 and the upper cover 11. Further, waterproof sealing rings 15 are installed at both circular holes 14, and a cover plate 16 for closing itself is also installed at the circular hole 14 on the side of the upper cover 11 away from the handle grip 3.

[0042] At the same time, a display screen is also installed on the top of the upper cover 11 of the present invention, and this display screen can display the gear state, throttle opening and diesel outboard engine fault code of the diesel outboard engine in real time. An externally connected CAN communication interface is also provided on the lower cover 12, and the information on the display screen can be extended to an external display screen.

[0043] The present invention further includes a control mechanism, which is built-in with a single-chip microcomputer that is signal-connected to the angle sensor 4 and the display screen. The single-chip microcomputer can be installed in the housing 1, and the single-chip microcomputer stores a warm-up program, a lifting program, a start protection program, an adjustment throttle opening program, and a gear recognition program.

[0044] In the present invention, the angle sensor 4 can detect the rotation angle of the driven gear 27. When the rotation angle is 0, it indicates that the handle grip 3 is not rotating at this time and is in the neutral gear state; when the rotation angle is 0 to 20° (excluding 20°), it indicates that the handle grip 3 is rotating clockwise to the forward gear at this time; when the rotation angle is 20°, it indicates that the handle grip 3 is in the forward gear at this time; when the rotation angle continues to increase, it indicates that the operator wants to increase the throttle to accelerate the diesel outboard engine forward. The larger the angle, the faster the speed; when the rotation angle is 0 to -20° (excluding -20°), it indicates that the handle grip 3 is rotating counterclockwise to the reverse gear at this time; when the rotation angle is -20°, it indicates that the handle grip 3 is in the reverse gear at this time; when the rotation angle continues to increase, it indicates that the operator wants to increase the throttle to accelerate the diesel outboard engine backward. The larger the angle, the faster the speed. In the present invention, the adjustment throttle opening program and the gear recognition program include that the single-chip microcomputer can judge the current state of the diesel outboard engine according to the angle information transmitted by the angle sensor 4 to the single-chip microcomputer and the above program content, and display it on the display screen or an external display screen. At the same time, the single-chip microcomputer can also judge the operator's intention according to the angle information and adjust the throttle opening of the diesel outboard engine, and display the throttle opening on the display screen or an external display screen. For example, when the operator wants to increase the throttle to accelerate the diesel outboard engine forward or backward, the single-chip microcomputer can make the throttle opening of the diesel outboard engine larger, so as to accelerate the ship. The larger the angle, the larger the throttle opening that the single-chip microcomputer makes for the diesel outboard engine.

[0045] The start protection program in the single-chip microcomputer includes the following content: when the diesel outboard engine fails to start for a long time or has started but still inputs a start instruction, it automatically stops starting to protect the start motor and the outboard engine; it detects the gear state and prohibits starting the diesel outboard engine in a non-neutral gear state to prevent misoperation. When the single-chip microcomputer protects the diesel outboard engine according to the start protection program, the single-chip microcomputer can simultaneously display the current state of the diesel outboard engine on the display screen.

[0046] When the water temperature of the diesel outboard engine is too low, the water temperature can be increased through the warm-up program in the single-chip microcomputer. To facilitate starting the warm-up program, a warm-up button can be set on the housing 1. When the warm-up button is pressed, the warm-up program is started with one key. To prevent accidental touch, two warm-up buttons can be set on the housing 1. The warm-up program can be started only when the two warm-up buttons are pressed simultaneously for a certain time; at the same time, to facilitate starting the lifting program, a lifting button can be set on the housing 1. When the lifting button is pressed, the lifting program is started with one key to adjust the lifting angle of the diesel outboard engine.

[0047] The working principle of the integrated handle for the diesel outboard engine in this embodiment is as follows: First, assemble and install the present invention completely.

[0048] When starting the ship, when pressing the warm-up button and the trimming button, the control signal is sent to the diesel outboard engine through the single-chip microcomputer, thereby adjusting the trimming angle of the diesel outboard engine and performing warm-up. After the trimming angle is adjusted and the warm-up is completed, rotate the handle grip 3 clockwise or counterclockwise, so as to adjust the diesel outboard engine to the forward or reverse gear. If the handle grip 3 continues to rotate, at this time, the single-chip microcomputer controls the throttle opening of the diesel outboard engine by reading the information of the angle sensor 4. The larger the angle, the larger the throttle opening of the diesel outboard engine controlled by the single-chip microcomputer, and the faster the ship speed.

[0049] At the same time, a start protection program for the diesel outboard engine is written in the single-chip microcomputer to protect the diesel outboard engine while starting the diesel outboard engine and adjusting the throttle size. The operating state information of the diesel outboard engine is sent to the display screen through the single-chip microcomputer and finally presented to the driver.

[0050] In the above embodiment, the present invention provides an integrated handle for a diesel outboard engine. Through the provided shifting mechanism, the present invention can pull the shift cable to realize the shifting operation of the diesel outboard engine; through the provided handle grip, the shifting mechanism can be driven to complete the shifting; through the provided control mechanism, the throttle opening of the diesel outboard engine can be controlled according to the detection result of the angle sensor; the control mechanism can also protect the diesel outboard engine when it starts, preventing damage caused by the abnormal operation of the motor for a long time when the diesel outboard engine starts or damage to the diesel outboard engine caused by the non-neutral state when starting; at the same time, the control mechanism can also complete operations such as warm-up and trimming of the diesel outboard engine with one key; the present invention integrates functions such as shifting, adjusting the throttle size, warm-up, trimming, and start protection of the diesel outboard engine, and each function can be completed on the present invention, which can simplify the operation steps while simplifying the structure and saving the installation space.
