[0025] Example 1

[0026] Reference Figures 1 to 3 The present embodiment provides a marine mini handwheel, which is characterized by comprising a casing, the casing being composed of a base 3 and a protective cover shell 14, the base 3 being arranged at the top of the protective cover shell 14, and the interior of the protective cover shell 14 being hollow; a rotating member, the rotating member being composed of a rotating handwheel 1, a rotating shaft 2, a rotating gear 8 and a main shaft bearing 15, and the rotating member being arranged inside the protective cover shell 14; a damping member, the damping member comprising a damping cam 4, a damping roller 5, and a damping friction ring 7, the damping member being arranged on the outer wall of the rotating member and cooperating with the rotating member; a sensor mounting support 9 is arranged at the inner wall of the protective cover shell 14, the outer wall of the sensor mounting support 9 is connected with an angle sensor 10, the signal of the angle sensor 10 is connected with a signal conditioning board 11, and the angle sensor 10 cooperates with the rotating member.

[0027] The spindle bearing 15 is arranged inside the base 3, and the rotating shaft 2 is connected to the base 3 through the spindle bearing 15. The rotating shaft 2 is rotatably connected to the outer wall of the base 3, and the bottom of the rotating handwheel 1 is fixedly connected to the top of the rotating shaft 2; the rotating handwheel 1 is a component directly operated and rotated by the staff, and the rotating shaft 2 is driven to rotate inside the base 3 by the rotating handwheel 1, and the purpose of the spindle bearing 15 is to ensure the smoothness and stability of the mechanical transmission.

[0028] The rotating gear 8 is fixedly connected to the bottom axis of the outer wall of the rotating shaft 2, and the rotating gear 8 and the angle sensor 10 are meshed with each other; through the meshing of the rotating gear 8 and the angle sensor 10, the angle sensor 10 can transmit the rotation angle information to the angle sensor 10 at a 1:1 ratio.

[0029] A damping friction ring 7 is fixedly connected to the inner wall of the base 3, and a damping cam 4 is fixedly connected to the outer wall of the rotating shaft 2, and the damping friction ring 7 is tightly fitted to the outer wall of the damping cam 4; due to the existence of the spindle bearing 15, there will be no damping feeling when the staff operates the rotating handwheel 1, so through the cooperation of the damping cam 4 and the damping friction ring 7, the staff has a certain damping feeling when operating the rotating handwheel 1. The purpose is to make it easier for the operator to perform more precise operations when the rotation angle of the rotating handwheel 1 cannot be accurately observed or the operator has a poor field of vision.

[0030] The outer wall of the base 3 is connected to a damping roller 5, and the damping cam 4 is in the shape of a circular ring as a whole. The damping cam 4 is provided with stop feedback points at 0°, 90°, 180°, and 270°, and several groups of stop feedback points of the damping cam 4 cooperate with the damping roller 5. By setting the stop points at the damping cam 4, the rotation threshold is divided, thereby further optimizing the operating feel and operating accuracy of the operator.

[0031] A cover 6 is connected to the bottom of the base 3, and the transmission shaft of the angle sensor 10 passes through the cover 6 and meshes with the rotating gear 8. The rotating parts and the damping parts are both located in the interlayer formed by the base 3 and the cover 6; through the combination of the base 3 and the cover 6, the rotating parts and the damping parts are both wrapped in the interlayer to achieve protection of the rotating parts and components.

[0032] A backlight control panel 12 is arranged on the top of the outer wall of the base 3, and a dial cover 13 is arranged on the top of the backlight control panel 12. The backlight control panel 12 is electrically connected to the dial cover 13. The outer wall of the dial cover 13 is provided with an angle scale, the purpose of which is to facilitate the operator to confirm the rotation angle, and the purpose of the backlight control panel 12 is to facilitate the operator to observe it in dim light or poor viewing conditions.

[0033] Furthermore, the function of the signal conditioning board 11 is to convert the resistance signal of the angle sensor 10 into a current signal of 4-20ma and provide a signal calibration function to further improve the accuracy and precision of the signal.

[0034] Among them, the angle sensor 10, the signal conditioning board 11 and the backlight control board 12 are all relatively common existing technologies, so they are not described here in detail.
