Description

Technical Field

[0001] This utility model relates to the field of engine control technology, and in particular to an engine control device. Background Technology

[0002] Traditional outboard motor gear control devices on boats are mechanical structures, which convert the rotation of a control lever into the push-pull motion of a mechanical cable to control the engine of the marine propulsion system. However, when faced with the multi-speed control requirements of high-horsepower outboard motors, traditional mechanical outboard motor control devices often suffer from problems such as unclear boundaries between different control gears, poor control feel, low control accuracy, high installation accuracy requirements, low level of intelligence, and inconvenient operation. Utility Model Content

[0003] To address the aforementioned technical deficiencies in the existing technology, this utility model provides an outboard motor control device to replace the traditional mechanical outboard motor power control device, thereby reducing the difficulty of operating and installing the outboard motor. Moreover, thanks to its electronic connection, this control device can be located away from the outboard motor, further improving navigation convenience, reducing outboard motor noise, and enhancing navigation safety.

[0004] The technical solution of this utility model to solve the above problems is as follows: An outboard motor control device is provided, the control device including a protective cover, a speed control arm, a connecting shaft, a control component, and a speed control component. The speed control arm is rotatably disposed on the outside of the protective cover via the connecting shaft. The control component is disposed inside the protective cover and is used to detect the rotation angle of the connecting shaft, and to electrically control the outboard motor gear according to the corresponding detection signal. The speed control component includes a gear position groove and a ball plunger. The gear position groove is disposed on the outer circumferential surface of the connecting shaft, and the ball plunger is disposed inside the protective cover, with the ball end of the ball plunger facing the movement trajectory of the gear position groove.

[0005] Furthermore, the gear position groove is configured as a spherical groove that adapts to the ball end of the ball plunger.

[0006] Furthermore, at least one positioning groove is provided on the outer circumferential surface of the connecting shaft, and a positioning pin is provided on the speed regulating arm. The speed regulating arm is positioned and connected to the connecting shaft by inserting the positioning pin into the positioning groove. The connecting shaft is rotatably inserted and installed on the outside of the protective cover.

[0007] Furthermore, the protective cover has a plug-in mounting hole for inserting the connecting shaft, and the ball plunger is radially installed in the plug-in mounting hole.

[0008] Furthermore, the gear position groove is provided in multiple ways, and the multiple gear position grooves are equidistantly arranged on the outer circumferential surface of the connecting shaft along the circumferential direction.

[0009] Furthermore, a pressure plate is provided in the insertion mounting hole. The pressure plate is disposed in the gap between the connecting shaft and the insertion mounting hole. A pressure plate hole is provided through the pressure plate. The ball plunger is inserted into the pressure plate hole, and the ball end of the ball plunger is positioned facing the connecting shaft.

[0010] Furthermore, a friction ring is sleeved on the connecting shaft, and the friction ring is also disposed between the pressure plate and the connecting shaft. The friction ring has a through hole for the ball plunger to extend into and reach the connecting shaft.

[0011] Furthermore, a damping adjustment locking plate is provided between the friction ring and the pressure plate. One end of the damping adjustment locking plate is rotatably connected to the pressure plate, and the other end is provided with a damping adjustment screw. The pressure plate is provided with a threaded connection hole for the damping adjustment screw to be connected.

[0012] Furthermore, the control component includes a main control circuit board, a detection sensor, and a signal converter. The detection sensor is electrically connected to the signal converter, and the signal converter is electrically connected to the main control circuit board. The main control circuit board is also electrically connected to the outboard motor's electronic control system. The main control circuit board is used to receive the detection signal sent by the signal converter, generate a corresponding gear control signal, and send it to the outboard motor's electronic control system.

[0013] Furthermore, the detection sensor is configured as a triaxial Hall sensor, and a magnetic attraction element is provided on the connecting shaft, with the magnetic attraction element facing the detection sensor.

[0014] The beneficial effects of this utility model are:

[0015] 1. The ball plunger can abut against the gear groove to slightly block the connecting shaft, so that the speed control arm can generate a swing gear corresponding to the number of gear grooves, thus corresponding one-to-one with the speed gears of the outboard motor, so as to control the operating conditions of the outboard motor.

[0016] 2. The positioning pin and positioning groove enable the speed control arm to be positioned in the circumferential direction when it is fixedly connected to the connecting shaft, so that the initial angle between the speed control arm and the upper surface of the protective cover can remain unchanged, that is, to ensure that the initial installation posture of multiple speed control arms is consistent and reasonable.

[0017] 3. Technicians can adjust the contact friction resistance between the friction ring and the connecting shaft by turning the damping adjustment screw, thereby effectively adjusting the swing feel of the speed control arm and preventing the speed control arm from sliding freely, thus improving the control feel.

Detailed Implementation

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 5 ,by Figure 5 Taking the indicated orientation as an example, in this embodiment, an outboard motor control device includes a protective housing 1, a speed control arm 2, a connecting shaft 3, a control component 4, and a speed control component. A plug-in mounting hole is provided on the left side wall of the protective housing 1, and the connecting shaft 3 is rotatably plugged into the plug-in mounting hole. The left end of the connecting shaft 3 extends outside the protective housing 1. The speed control arm 2 is perpendicular to the connecting shaft 3, and its lower end is fixedly connected to the left end of the connecting shaft 3. The control component 4 is disposed inside the protective housing 1 and is used to detect the rotation angle of the connecting shaft 3. The speed control component includes a gear position groove 51, a positioning groove 52, and a ball plunger 53. There are three gear position grooves 51, which are equidistantly located on the left side of the outer circumferential surface of the connecting shaft 3. There are two positioning grooves 52, which are symmetrically arranged on the outer circumferential surface of the connecting shaft 3 relative to the gear position groove 51 located in the middle of the three gear position grooves 51. Both positioning grooves 52 extend to the shaft end face of the connecting shaft 3.

[0030] In this embodiment, technicians can swing the speed control arm 2 to different angles so that the control component 4 can identify them and control the outboard motor to be in different speed gears. Moreover, technicians can also associate the different speed gears of the outboard motor with different angle values, and sequentially open the corresponding number of gear grooves 51 on the outer circumferential surface of the connecting shaft 3 according to the angle difference between the different gears. This way, when the speed control arm 2 rotates to the corresponding gear angle, the ball end of the ball plunger 53 can just abut against the corresponding gear groove 51, thereby locking the connecting shaft 3 and the speed control arm 2, so that the outboard motor can always be in the gear operation state without external influence.

[0031] Meanwhile, in this embodiment, the gear position groove 51 is set as a spherical groove that matches the ball head end of the ball plunger 53, so that when it is necessary to adjust or change the working gear of the outboard motor, the technician can manually drive the speed control arm 2 to swing, thereby causing the ball head end of the ball plunger 53 to retract inward, so that the ball plunger 53 can disengage from the corresponding gear position groove 51, so as to adjust the outboard motor gear.

[0032] In addition, when the connecting shaft 3 is fixedly installed at the lower end of the speed control arm 2, the speed control arm 2 and the connecting shaft 3 can be fixedly connected by inserting each of the two positioning pins into a positioning groove. The positioning can be understood as follows: with the third gear groove 51 located between the two gear grooves 51 as a reference, when the connecting shaft 3 is fixedly installed at the lower end of any speed control arm 2 with the same size, the distance between the speed control arm 2 and the third gear groove 51 in the middle is the same. Thus, when any speed control arm 2 of the same size is installed on the side of the protective cover 1 through the connecting shaft 3, the angle between the speed control arm 2 and the upper inclined surface of the protective cover 1 is the same.

[0033] Further, please refer to Figures 3 to 5 ,by Figure 5 Taking the orientation shown as an example, in this embodiment, a pressure plate 54 is also provided in the insertion mounting hole. The pressure plate 54 is fixed in the insertion mounting hole by bolts. The center of the pressure plate 54 is provided with a through hole, and the connecting shaft 3 is inserted into the through hole. The left end of the pressure plate 54 is integrally formed with two opposing arc-shaped flanges. The inner walls of the two arc-shaped flanges are seamlessly connected to the inner wall of the central through hole of the pressure plate 54. The inner side of the lower arc-shaped flange is also provided with an arc-shaped damping adjustment locking piece 56. The front right end of the damping adjustment locking piece 56 is rotatably connected to the pressure plate 54 by bolts, and the rear left end is provided with a damping adjustment screw 57 vertically. The damping adjustment screw 57 is threadedly connected to the upper arc-shaped flange.

[0034] Further, please refer to Figure 3 , Figure 3 The lower left inner arc surface of the intermediate pressure plate 54 is higher than the lower right inner arc surface, so as to... Figure 3 Taking the orientation shown as an example, this is because, in this embodiment, a rotation limiting protrusion is integrally provided downward in the middle of the connecting shaft 3, and an arc-shaped rotation limiting groove is also provided at the lower part of the central through hole of the pressure plate 54. The rotation limiting groove is used to accommodate the rotation limiting protrusion and allows the rotation limiting protrusion to slide ±60° in the circumferential direction within the rotation limiting groove. Subsequently, it is blocked and limited by the two end side walls of the rotation limiting groove to limit the maximum rotation angle of the connecting shaft 3 and the speed regulating arm 2.

[0035] To address this, technicians fitted a friction ring 55 onto the connecting shaft 3, positioning it between the arc-shaped flange and the damping adjustment locking plate 56. By turning the damping adjustment screw 57, the pressure applied to the friction ring 55 by the damping adjustment locking plate 56 and the upper arc-shaped flange can be controlled, thereby adjusting the friction resistance between the friction ring 55 and the connecting shaft 3, and thus adjusting the swing resistance of the speed control arm 2 to adjust the control feel.

[0036] In addition, in this embodiment, the upper end of the pressure plate 54 is radially provided with a through pressure plate hole, the upper end of the friction ring 55 is provided with a through hole, the ball head plunger 53 is vertically inserted into the pressure plate hole, and its lower end also passes through the through hole to contact the surface of the connecting shaft 3.

[0037] Further, please refer to Figure 1 , Figure 2 ,as well as Figure 5 In this embodiment, the control component 4 includes a main control circuit board 41, a detection sensor 42, and a signal converter. The detection sensor 42 is a triaxial Hall sensor, and the signal converter is a signal amplification circuit board. The detection sensor 42 is electrically connected to the signal converter, and the detection sensor 42 is positioned directly opposite the right end of the connecting shaft 3. A magnetic chuck 43 is embedded on the right end of the connecting shaft 3. The signal output terminal of the signal converter is electrically connected to the main control circuit board 41, and the main control circuit board 41 is connected to the outboard motor's electrical control system.

[0038] In response, when the technician operates the cranking arm 2, the detection sensor 42 can detect the magnetic suction component 43 and, based on the rotation angle of the magnetic suction component 43, send electrical signals of different current intensities to the main control circuit board 41 via the signal converter. The main control circuit board 41 then receives and identifies the electrical signals of different current intensities and sends corresponding control commands representing different gears to the outboard motor's electronic control system, thereby controlling the outboard motor's gears.

[0039] It should be noted that in this embodiment, when the speed regulating arm 2 is also provided with a control button, the connecting shaft 3 is axially provided with a through hole that runs through both the left and right ends. The electrical connection between the control button on the speed regulating arm 2 and the main control circuit board 41 is wired through this through hole.

[0040] Example 2:

[0041] Unlike Example 1, please refer to Figure 6In this embodiment, there are two speed control arms 2, two connecting shafts 3, two speed control components, and two control components 4. One speed control arm 2, one connecting shaft 3, one speed control component, and one control component 4 together constitute a set of control mechanisms. The two sets of control components are symmetrically arranged on the left and right sides of the protective cover 1 to control the two outboard motors respectively, thereby realizing turning control, etc.

[0042] It should be noted that in this embodiment, the structure, installation method, and working principle of the speed regulating arm 2, the connecting shaft 3, the speed regulating component, and the control component 4 are the same as in Embodiment 1.

[0043] Anything not mentioned above applies to existing technologies.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
