In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0038] According to the present invention, there is provided a ship steering wheel, Figures 1 to 4 As shown, the ship steering wheel of this embodiment includes a control mechanism, a slewing mechanism, a push rod mechanism and a signal acquisition module 4, and the slewing mechanism and the push rod mechanism are both connected to the control mechanism, so that by driving the control mechanism to move, the slewing mechanism and the control mechanism can be driven to move respectively, and then the first rudder and the second rudder can be controlled to move respectively, that is, the steering wheel can control two (groups) of rudders at the same time. In the following, the specific structure and connection relationship of the above-mentioned mechanisms of the ship steering wheel will be described in detail.

[0039] In this embodiment, if Figures 1 to 4As shown, the ship steering wheel is provided with a shell 5, and the slewing mechanism, the push rod mechanism, and the signal acquisition module 4 are all located inside the shell 5, and the shell 5 can protect the above-mentioned mechanisms; in addition, the shell 5 can facilitate the assembly of the steering wheel with the ship, and the specific structure and size of the shell 5 are not specifically limited. For example, the shell 5 in this embodiment is formed into a wedge-shaped structure.

[0040] Specifically, Figures 2 to 4 As shown, the control mechanism in this embodiment is provided with a cross shaft, which includes a longitudinal axis 11 and a transverse axis 12 sleeved on the outer side of the longitudinal axis 11. The longitudinal axis 11 is formed into a columnar structure, and a wheel 10 is provided at the first end in the axial direction thereof, so that the crew can control the rotation or swing of the longitudinal axis 11 (the wheel 10 and the longitudinal axis 11 are connected by a pin); the second end in the axial direction of the longitudinal axis 11 is formed into a stepped structure and connected to the above-mentioned rotary mechanism. In addition, an oblong hole is formed at the top of the above-mentioned shell 5, and the first end of the longitudinal axis 11 extends to the outside of the shell 5 through the oblong hole. It should be noted that the specification of the oblong hole should correspond to the longitudinal axis 11, that is, the longitudinal axis 11 will not interfere with the oblong hole when rotating, and the longitudinal axis 11 can swing along the extension direction of the oblong hole (the oblong hole plays a limiting role for the swinging longitudinal axis 11).

[0041] Furthermore, in this embodiment, the horizontal axis 12 is arranged perpendicular to the longitudinal axis 11, the middle section of the horizontal axis 12 is formed into a rectangular parallelepiped structure, the longitudinal axis 11 passes through the middle section of the horizontal axis 12 and is rotatably connected to the horizontal axis 12 through the sleeve 14, that is, the longitudinal axis 11 can rotate relative to the horizontal axis 12; in addition, both ends of the axial direction of the horizontal axis 12 are formed into columnar stepped structures to facilitate the connection of the push rod structure. Figure 4 As shown, bearing assemblies (including a bearing 131 sleeved on the outer side of the transverse axis 12 and a bearing seat 130 connecting the bearing 131 to the top of the housing 5) are sleeved at both ends of the transverse axis 12 in the axial direction. In this way, a stable connection between the operating mechanism and the housing 5 can be achieved, and through the bearing 131, the transverse axis 12 can be driven to rotate synchronously when the longitudinal axis 11 swings.

[0042] like Figures 2 to 3As shown, the rotary mechanism in this embodiment includes a rotary driving gear 20 and a rotary driven gear 21 corresponding to the rotary driving gear 20, and the rotary driving gear 20 is sleeved on the step of the second end of the longitudinal axis 11; further, the rotary mechanism also includes a first fixed seat 24 formed into a quasi-L-shaped structure, so that the vertical section of the first fixed seat 24 can be connected to the middle section of the horizontal axis 12 by screws, and the horizontal section of the first fixed seat 24 is used to connect the rotary potentiometer 22, but the rotary potentiometer 22 is rotatably connected to the first fixed seat 24 (that is, the first fixed seat 24 only serves as a support to improve the assembly stability of the rotary potentiometer 22), and the connecting shaft of the rotary potentiometer 22 passes through the first fixed seat 24, and the above-mentioned rotary driven gear 21 is sleeved on the connecting shaft of the rotary potentiometer 22.

[0043] Thus, when the longitudinal shaft 11 is driven to rotate, the rotary driving gear 20 can rotate synchronously, thereby driving the rotary driven gear 21 meshing therewith to rotate, and then driving the rotary potentiometer 22 to rotate synchronously. Based on the inherent function of the rotary potentiometer 22, it can convert the rotation angle into a first angle signal output.

[0044] In addition, in order to improve the comfort of the crew during operation, the slewing mechanism is also provided with a slewing damper 23, a second fixing seat 25 and a first limit assembly. Figure 3 As shown, the second fixing seat 25 is also formed into a quasi-L-shaped structure, the vertical section of which is connected to the middle section of the horizontal shaft 12, and the horizontal section of which is sleeved on the second section of the longitudinal shaft 11 and forms a gap with the longitudinal shaft 11 to facilitate the rotation of the longitudinal shaft 11. Further, the slewing damper 23 is sleeved on the step of the second section of the longitudinal shaft 11, and the slewing damper 23 is located at the top of the horizontal section of the second fixing seat 25 (facing the slewing driving gear 20) and connected to the second fixing seat 25. In this way, when the crew drives the longitudinal shaft 11 to rotate, the slewing damper 23 can provide a resistance in the opposite direction (the inherent function of the slewing damper 23) to prevent the longitudinal shaft 11 from rotating excessively.

[0045] Furthermore, if Figure 3 As shown, the first limiting assembly includes a limiting plate 260 fixed to the outer side of the longitudinal axis 11, and the limiting plate 260 is located at the bottom end of the horizontal section away from the rotary driving gear 20. The bottom end of the horizontal section of the second fixed seat 25 is formed with an arc-shaped limiting groove (the arc of which is determined according to the rotation range of the longitudinal axis 11), and the top of the limiting plate 260 is provided with a limiting member 261 corresponding to the limiting groove. In this way, when the longitudinal axis 11 rotates (the transverse axis 12 does not move), the limiting plate 260 and the limiting member 261 rotate synchronously with the longitudinal axis 11, and the second fixed seat 25 remains in a non-moving state in accordance with the transverse axis 12, so that the limiting member 261 can slide in the limiting groove to ensure that the longitudinal axis 11 can rotate within the specified range.

[0046] In addition, the limiting plate 260 is also provided with a first elastic component 262. Specifically, a threaded hole is formed at the top of the limiting plate 260, and the first elastic component 262 includes a threaded barrel 2620 correspondingly connected to the threaded hole, and a spring 2621 is arranged inside the threaded barrel 2620, that is, the first end of the spring 2621 is fixed to the threaded barrel 2620, and the second end thereof is fixed with a ball 2622. Correspondingly, a plurality of grooves corresponding to the ball 2622 are arranged at the bottom end of the horizontal section of the second fixing seat 25, and the plurality of grooves are determined according to the rotation range and rotation direction of the longitudinal shaft 11. When the spring 2621 is in a natural state, the ball 2622 can extend into the groove, and when the crew drives the longitudinal shaft 11 to rotate, the spring 2621 is compressed by force, and the ball 2622 can extend into another groove as the longitudinal shaft 11 rotates. Such an arrangement enables the crew to have a stronger sense of operation when driving the longitudinal shaft 11 to rotate. Preferably, the plurality of grooves can be evenly arranged at certain angle intervals so that the crew can know the rotation angle of the longitudinal shaft 11.

[0047] In this embodiment, if Figure 4 As shown, in order to further improve the stability of the longitudinal axis 11 during rotation, that is, to avoid excessive rotation of the longitudinal axis 11, two first limit columns 120 are arranged at the top of the middle section of the transverse axis 12, and the two first limit columns 120 are arranged at intervals along the axial direction of the transverse axis 12; correspondingly, the outer side wall of the longitudinal axis 11 is provided with a protruding second limit column 110, and when the second limit column 110 abuts against the two first limit columns 120, it represents that the longitudinal axis 11 has been rotated to the extreme position.

[0048] Similarly, Figure 2 and Figure 4 As shown, the push rod mechanism in this embodiment includes a push rod driving gear 30 and a push rod driven gear 31 corresponding to the push rod driving gear 30, and the push rod driving gear 30 is sleeved on the step of the second end of the horizontal axis 12; further, the push rod mechanism also includes a third fixed seat 34 formed as an L-shaped structure, so that the horizontal section of the third fixed seat 34 can be connected to the top of the shell 5 by screws, and the vertical section of the third fixed seat 34 is sleeved on the second end of the horizontal axis 12 (forming a gap with the horizontal axis 12), and the push rod potentiometer 32 is rotatably connected to the end face of the vertical section of the third fixed seat 34 away from the longitudinal axis 11, and the connecting shaft of the push rod potentiometer 32 passes through the third fixed seat 34, and the above-mentioned push rod driven gear 31 is sleeved on the connecting shaft of the push rod potentiometer 32.

[0049] In this way, when the longitudinal axis 11 is driven to swing, the transverse axis 12 rotates accordingly (the third fixing seat 34 does not rotate), so that the push rod driving gear 30 can rotate synchronously, so as to drive the push rod driven gear 31 meshing with it to rotate, and then drive the push rod potentiometer 32 to rotate synchronously. Based on the inherent function of the push rod potentiometer 32, it can convert the rotation angle into a second angle signal output.

[0050] In addition, a second limit assembly is also provided at the second end of the axial direction of the transverse axis 12, such as Figure 4 As shown, the second limiting assembly includes a limiting arm 35 which is sleeved on the outer side of the transverse axis 12, and the limiting arm 35 can rotate synchronously with the transverse axis 12; the limiting arm 35 is provided with a second elastic assembly 36 which is similar to the first elastic assembly 262, and correspondingly, the end surface of the vertical section of the third fixed plate away from the longitudinal axis 11 is also provided with a plurality of grooves arranged according to the rotation direction of the transverse axis 12.

[0051] In addition, the push rod mechanism also includes a push rod damper 33 sleeved on the first end of the axial direction of the transverse shaft 12. Specifically, a connecting frame is sleeved on the first end of the axial direction of the transverse shaft 12, the connecting frame forms a gap with the transverse shaft 12 and is fixedly connected to the bearing seat 130, and the push rod damper 33 is connected to the end surface of the connecting frame away from the bearing seat 130. When the crew drives the longitudinal shaft 11 to swing to drive the transverse shaft 12 to rotate, the push rod damper 33 can provide a resistance in the opposite direction (the inherent function of the push rod damper 33) to prevent the transverse shaft 12 from rotating excessively.

[0052] In this embodiment, as shown in the figure, a signal acquisition module 4 is provided at the inner bottom of the shell 5, which can receive the first angle signal and the second angle signal, and respectively control the first rudder and the second rudder to move at a certain angle (this is the conventional setting of the existing steering wheel, so it will not be repeated).

[0053] According to the ship steering wheel of the present invention, by driving the longitudinal axis 11 to rotate, the slewing mechanism can be driven to move accordingly, so that the slewing potentiometer 22 can output a first angle signal correspondingly, and the signal acquisition module 4 can receive the signal and control the first rudder according to the signal; by driving the longitudinal axis 11 to swing, the transverse axis 12 can be driven to rotate, thereby driving the push rod mechanism to move accordingly, so that the push rod potentiometer 32 can output a second angle signal correspondingly, and the signal acquisition module 4 can receive the signal and control the second rudder according to the signal. In this way, two (groups) of rudders can be controlled simultaneously by the steering wheel, which effectively reduces the space required for arranging the steering wheel and saves the cost of manpower training.

[0054] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
