Description

Technical Field

[0001] This utility model belongs to the field of ship parts technology, specifically relating to a ship propeller control handle and a ship. Background Technology

[0002] In existing ship propulsion control systems, the propeller control handle, as a key human-machine interface component, is mainly used to control the ship's forward and reverse movements, as well as the throttle position (i.e., propulsion power). Traditional ship propeller control handles typically employ complex mechanical linkage structures, such as linkage mechanisms, gear transmissions, or cable systems, to convert the rotational motion of the handle itself into linear or angular displacement control of the propeller actuators (such as throttle levers or directional valves). While such mechanical structures can achieve basic control functions to a certain extent, they have many inherent drawbacks.

[0003] First, the long mechanical transmission path and numerous components result in a complex and bulky overall structure, increasing manufacturing and assembly difficulties and significantly raising production costs. Second, due to its reliance on physical contact for motion transmission, it is prone to wear, loosening, and even jamming during long-term use, affecting control accuracy and response sensitivity, and requiring frequent maintenance and high repair costs. Furthermore, in modern marine systems requiring precise feedback of handle angles for electronic or intelligent control, traditional purely mechanical structures struggle to integrate high-precision angle sensing devices, limiting their application in automated and digital marine platforms.

[0004] Although some improvement solutions attempt to introduce angle detection elements such as potentiometers or encoders, the lack of an effective coaxial constraint mechanism between the handle rotation center and the installation position of the sensing element often leads to problems such as signal drift and poor repeatability due to assembly errors or structural deformation, which further reduces the reliability and service life of the system.

[0005] Therefore, there is an urgent need for a new type of ship propeller control handle that is simple in structure, cost-controllable, easy to maintain, and can effectively ensure the accuracy of angle signal acquisition, in order to overcome the above-mentioned shortcomings of the existing technology. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a ship propeller control handle and a ship in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a ship propeller control handle is proposed, including: a main support, on which an arc-shaped track groove is provided; The handle body is rotatably mounted on the main support, and the center of the track groove is located on the rotation center line of the handle body; A guide post is provided on the handle body and slidably inserted into the track groove, and the center line of the guide post is parallel to the rotation center line of the handle body. The mounting base is fixedly connected to the handle body, and one end of the guide post is fixedly connected to the mounting base; A connecting frame is fixedly mounted on the main support and is positioned opposite to the handle body; A signal processing unit includes a trigger and a signal receiver. The trigger is fixedly mounted on the mounting base and rotates synchronously with it. The signal receiver is fixedly mounted on the connecting frame. When the trigger rotates synchronously with the handle body, the signal receiver detects the rotation angle of the trigger in real time and outputs a corresponding rotation angle signal. The trajectory groove constrains the movement trajectory of the guide post, so that the rotation center of the mounting base and the trigger element always coincides with the rotation center line of the handle body; The fixed arrangement of the connecting frame ensures that the signal receiver on it maintains a constant distance from the trigger end face of the trigger.

[0008] In the aforementioned ship propeller control handle, a positioning recess is provided on the main support, and a positioning protrusion is movably provided on the handle body. The positioning protrusion and the positioning recess can be separably fitted together to position the handle body in a preset position.

[0009] In the aforementioned ship propeller control handle, the handle body is provided with a receiving hole, the positioning protrusion is slidably disposed in the receiving hole, and an elastic element is provided in the receiving hole. One end of the elastic element abuts against the hole wall of the receiving hole, and the other end abuts against the positioning protrusion and forces the positioning protrusion to extend out of the receiving hole, so as to allow the positioning protrusion to partially extend or retract into the receiving hole.

[0010] In the aforementioned ship propeller control handle, the connecting frame is provided with three connecting parts, which are distributed at equal angles along the rotation center line of the handle body. The main support is provided with threaded holes corresponding to the connecting parts. Bolts pass through the connecting parts and are screwed into the threaded holes to fix the connecting frame to the main support.

[0011] In one of the aforementioned ship propeller control handles, a buffer portion is provided at one end of the handle body facing the main support. The buffer portion corresponds to at least one of the bolts, and the end of the bolt abuts against the buffer portion to provide frictional damping for the rotation of the handle body.

[0012] In the aforementioned ship propeller control handle, a rotating column is provided at one end of the handle body facing the main support, and a rotating hole is provided on the main support. The rotating column is inserted into the rotating hole, and a bearing is provided between the two for the handle body to be rotatably mounted on the main support.

[0013] The aforementioned ship propeller control handle also includes a connecting rod, one end of which passes through the mounting base and is threaded onto the handle body for connecting the mounting base and the handle body.

[0014] In the aforementioned ship propeller control handle, a connecting block is fixedly provided at one end of the mounting base away from the handle body. The connecting block is provided with a mounting hole, the center line of which is collinear with the rotation center line of the handle body, and the trigger is fixed in the mounting hole.

[0015] In the aforementioned ship propeller control handle, the signal processing unit further includes a circuit board, which is fixed on the connecting frame. The signal receiver is a Hall sensor electrically connected to the circuit board, and the trigger is a magnet.

[0016] This utility model solves the above-mentioned technical problems and also proposes a ship, including the aforementioned ship propeller control handle.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) By combining the track groove and the guide column, and the connection between the mounting base and the handle body, high coaxiality of rotational motion transmission is achieved, which effectively avoids the signal offset problem caused by assembly error, structural deformation or wear in traditional mechanical transmission, and significantly improves the accuracy and repeatability of angle detection; at the same time, it eliminates the complex mechanical conversion mechanism such as connecting rods and cables, simplifies the overall structure, and reduces manufacturing costs and failure rate.

[0019] (2) By setting a positioning recess on the main support and a separable and engaging positioning protrusion on the handle body, reliable positioning of the handle in preset positions (such as neutral, idle, or forward / reverse switching position of the thruster) is achieved. This design replaces the traditional method of positioning that relies on friction or complex locking mechanisms. It is not only simple in structure and intuitive in operation, but also avoids the problem of positioning failure due to mechanical wear, thus improving operational safety and service life.

[0020] (3) The connecting frame is threaded to the main support through three equally angularly distributed connecting parts, forming a stable and symmetrical fixed structure. This three-point positioning method not only improves the installation rigidity and torsional resistance of the connecting frame, but also ensures the spatial orientation stability of the signal receiver, avoiding changes in the sensing distance due to vibration or loosening, thereby ensuring the stability of angle signal acquisition and solving the problem of signal drift caused by insecure fixing in traditional structures.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] like Figures 1 to 9 As shown, this utility model provides a ship propeller control handle, including: a main support 100, a handle body 200, a guide column 210, a mounting base 300, a connecting frame 400, and a signal processing unit 500.

[0034] Specifically, the main support 100 serves as a rotating support component for the handle body 200, and has an arc-shaped track groove 110 on it; the handle body 200 is rotatably mounted on the main support 100, and the center of the track groove 110 is located on the rotation center line of the handle body 200.

[0035] The guide post 210 is disposed on the handle body 200 and slidably inserted into the track groove 110, with its axis parallel to the rotation center line of the handle body 200. The mounting base 300 is fixedly connected to the handle body 200, and one end of the guide post 210 is fixedly connected to the mounting base 300. The connecting bracket 400 is fixedly mounted on the main support 100 and arranged opposite to the handle body 200.

[0036] The signal processing unit 500 includes a trigger 510 and a signal receiver 520. The trigger 510 is fixed to the mounting base 300 and rotates synchronously with the mounting base 300 and the handle body 200; the signal receiver 520 is fixed to the connecting bracket 400.

[0037] When the handle body 200 rotates, the trigger 510 rotates accordingly, and the signal receiver 520 detects its position change in real time and outputs the corresponding rotation angle signal. After being processed by the signal processing unit 500, this signal is used to control the ship's propulsion device to perform corresponding acceleration, deceleration, or reverse propulsion operations.

[0038] The arc-shaped track groove 110 constrains the movement path of the guide post 210, ensuring that the rotation axis of the mounting base 300 and the trigger 510 always coincides with the rotation center line of the handle body 200. This guarantees that the geometric center of the trigger 510 is strictly aligned with its rotation axis, avoiding detection errors in the signal receiver 520 due to skewness or wobbling. Simultaneously, because the connecting bracket 400 is fixedly installed, a constant distance is maintained between the signal receiver 520 and the trigger end face of the trigger 510, further ensuring the stability and accuracy of angle signal acquisition.

[0039] This solution achieves high coaxiality rotational motion transmission through the cooperation of the track groove 110 and the guide post 210, combined with the connection between the mounting base 300 and the handle body 200. This effectively avoids the signal offset problem caused by assembly errors, structural deformation or wear in traditional mechanical transmission, and significantly improves the accuracy and repeatability of angle detection. At the same time, it eliminates the need for complex mechanical conversion mechanisms such as linkages and cables, simplifies the overall structure, and reduces manufacturing costs and failure rate.

[0040] In one embodiment, the control handle further includes a base and a housing. The main support 100 and the connecting frame 400 are both mounted on the base. The housing cooperates with and encloses the base, forming a sealed chamber inside to house and protect internal components such as the main support 100 and the connecting frame 400. The handle body 200 has an inverted L-shaped structure, with one end rotatably connected to the main support 100 and the other end extending along the outer contour of the housing and protruding to the upper surface of the housing for easy user operation.

[0041] Furthermore, a positioning recess 120 is provided on the main support 100, and a movable positioning protrusion 220 is provided on the handle body 200. The positioning protrusion 220 and the positioning recess 120 can be separably engaged to stably position the handle body 200 in a preset position (e.g., neutral, idle, or thruster forward / reverse switching position).

[0042] This design replaces the traditional method of positioning that relies on friction or complex locking mechanisms. It is not only simpler in structure and more intuitive to operate, but also avoids the risk of positioning failure due to mechanical wear, thereby improving the safety of operation and the service life of the device.

[0043] Furthermore, a receiving hole 230 is provided on the handle body 200, and the positioning protrusion 220 can be slidably disposed within the receiving hole 230. An elastic member is installed in the receiving hole 230, one end of which is in close contact with the hole wall of the receiving hole 230, and the other end is pressed against the positioning protrusion 220, so that the positioning protrusion 220 is pushed out of the receiving hole 230, allowing it to partially extend or retract into the receiving hole 230.

[0044] This elastic reset mechanism ensures that the positioning protrusion 220 can automatically pop out or retract when needed, completing the engagement or disengagement with the positioning recess 120 without additional manual operation. This design has the advantages of compact structure and rapid response, solving the jamming and fatigue failure problems commonly found in traditional manual locking or the use of complex spring assemblies, simplifying the overall structure, enhancing system reliability, and facilitating maintenance.

[0045] It is worth mentioning that the connecting frame 400 is provided with three connecting parts 410. The three connecting parts 410 are distributed at equal angles along the rotation center line of the handle body 200. The main support 100 is provided with threaded holes 130 that correspond one-to-one with the connecting parts 410. Bolts pass through the connecting parts 410 and are screwed into the threaded holes 130 to fix the connecting frame 400 to the main support 100.

[0046] The connecting frame 400 is threadedly connected to the main support 100 via three equally angled connecting parts 410, forming a stable and symmetrical fixed structure. This three-point positioning method not only improves the installation rigidity and torsional resistance of the connecting frame 400, but also ensures the spatial orientation stability of the signal receiver 520, avoiding changes in the sensing distance due to vibration or loosening, thereby ensuring the stability of angle signal acquisition and solving the problem of signal drift caused by insecure fixing in traditional structures.

[0047] The handle body 200 has a buffer part 240 at one end facing the main support 100. The buffer part 240 corresponds to at least one bolt for fixing the connecting bracket 400. The end of the bolt contacts and abuts against the buffer part 240. During the rotation of the handle body 200, damping is generated by friction, thereby providing a stable and clear operating feel.

[0048] The buffer section 240 can be implemented in various structural forms, such as processing a leather-like texture or other micro-textured texture on the surface of the handle body 200, or attaching flexible friction materials such as felt to the corresponding positions. These structures increase the friction between the handle and the bolt end face, creating a moderate damping effect when the handle is rotated, effectively improving the feedback and controllability of the operation.

[0049] In addition, a rotating column 250 is provided at the end of the handle body 200 facing the main support 100, and a corresponding rotating hole 140 is provided on the main support 100. The rotating column 250 is inserted into the rotating hole 140, and a bearing 260 is installed between the two to achieve smooth rotation of the handle body 200 relative to the main support 100.

[0050] The rotating column 250 can be integrally formed with the handle body 200, or it can be fixedly connected by welding, threaded connection, snap-fit, or adhesive. Through the cooperation between the rotating column 250 and the rotating hole 140, combined with the support structure of the built-in bearing 260, rotational resistance is significantly reduced, making operation smoother. Compared with traditional bushing structures or direct metal-metal friction pairs, this design has advantages such as good wear resistance, long service life, and easy disassembly and maintenance, effectively solving the problems of jamming, shaking, or increased clearance caused by wear of rotating parts in traditional handles.

[0051] This solution also includes a connecting rod 600, one end of which passes through the mounting base 300 and is threaded to the handle body 200 for fixing the mounting base 300 to the handle body 200.

[0052] Preferably, the connecting rod 600 is a countersunk screw. The mounting base 300 is provided with a stepped hole. When the connecting rod 600 is screwed into the handle body 200, its countersunk head abuts against the large-diameter end face of the stepped hole, thereby pressing the mounting base 300 onto the handle body 200 to achieve reliable fixation.

[0053] The mounting base 300 and the handle body 200 are connected by threads via the connecting rod 600, which not only enhances the rigidity of the connection between the two but also facilitates modular assembly and subsequent maintenance and replacement. This design avoids the non-removability of traditional welding or riveting processes, significantly improving maintainability; at the same time, it ensures the reliability of synchronous rotation between the mounting base 300 and the handle body 200, effectively preventing the problem of inaccurate angle signals due to loose connections.

[0054] The mounting base 300 is fixedly provided with a connecting block 310 at one end away from the handle body 200. The connecting block 310 is provided with a mounting hole 320. The center line of the mounting hole 320 is collinear with the rotation center line of the handle body 200. The trigger 510 is fixed in the mounting hole 320.

[0055] The connecting block 310 and the mounting base 300 can be fixedly connected by welding, threaded connection, or snap-fit. By providing a connecting block 310 with a highly coaxial mounting hole 320 at the end of the mounting base 300 opposite to the handle body 200, a precise axial positioning reference is provided for the trigger 510. This structure ensures that the trigger 510 is precisely located on the handle's rotation axis, thereby significantly improving the linearity and consistency of the signal detected by the Hall sensor, fundamentally solving the angle detection error problem caused by traditional non-coaxial mounting.

[0056] The signal processing unit 500 also includes a circuit board 530, which is fixed on the connector 400. The signal receiver 520 is a Hall sensor that is soldered or mounted on the circuit board 530, and the trigger 510 is a magnet.

[0057] This solution employs a non-contact angle detection structure using a magnet and a Hall sensor, integrating the circuit board 530 onto the connector 400, completely eliminating wear-prone sensing elements such as potentiometers that rely on mechanical contacts. This design not only significantly improves the long-term stability and electromagnetic interference resistance of angle detection but also greatly extends the system's lifespan. Furthermore, the elimination of sliding electrical contact structures simplifies internal wiring and enhances the reliability of the sealing design, effectively reducing the maintenance difficulty and cost of the electronic system.

[0058] The signal receiver 520 may include one or more Hall effect sensors (or other magnetic sensitive elements, such as anisotropic magnetoresistive sensors (AMR) or giant magnetoresistive sensors (GMR)) mounted on the circuit board 530 for non-contact detection of the magnetic field changes generated by the magnet rotating synchronously with the handle body 200 at different angular positions, thereby outputting the corresponding rotation angle signal.

[0059] By designing the trigger 510 as a magnet and cooperating with the Hall sensor on the circuit board 530, highly reliable non-contact detection of the handle body's 200° rotation angle is achieved. This solution fundamentally avoids the risk of signal drift or failure caused by wear, oxidation, or contamination of traditional contact sensing elements, significantly improving the accuracy of signal acquisition, the stability of system operation, and the overall service life.

[0060] This proposal also suggests a vessel that includes the aforementioned control handle.

[0061] In summary, this solution provides a ship propeller control handle that is simple in structure, reliable in performance, easy to maintain, and has high signal accuracy. By adopting a coaxial constraint mechanism in which the arc-shaped track groove 110 cooperates with the guide post 210, it is ensured that the trigger element 510 always rotates around the rotation center line of the handle body 200, fundamentally solving the problem of angle signal drift caused by assembly errors or wear in traditional mechanical structures. At the same time, it eliminates complex transmission components such as connecting rods and cables, greatly simplifying the overall structure and effectively reducing manufacturing costs and failure rates.

[0062] Furthermore, the automatic positioning of the preset position is achieved through the elastic positioning protrusion 220, the three-point symmetrical bolt fixing connection frame 400 ensures the stability of the sensor, the bolts also serve as damping elements to optimize the operating feel, the bearing 260 supports and improves the smoothness of rotation, the modular connection facilitates disassembly and maintenance, and the non-contact Hall sensor and magnet constitute a highly reliable signal processing unit 500, which comprehensively overcomes the defects of the existing technology such as inaccurate operation, easy wear, difficult maintenance, and short life.
