The torsion spring 2811 is sleeved on the second rotating shaft 247, and one of the torsion arms is limited on the housing 25 (specifically, the limit can be achieved by setting a jack or a block to ensure that the torsion arm and the housing 25 remain relatively stationary), The other torsion arm is limited on the inner shell 24 (specifically, the limit can be realized by providing a socket or a stopper, etc., to ensure that the torsion arm and the inner are kept relatively stationary). One end of the tension spring 2812 is hung on the first limiting post 248 , and the other end is hung on the second limiting post 256 . When the dial 21 is pressed, the inner casing 24 swings relative to the outer casing 25, so that the angle between the two torsion arms changes, thereby enhancing the pressing feeling. By adjusting the compression amount and stiffness of the torsion spring 2811 and the tension spring 2812, the strength of the pressing feel can be adjusted.

The principle and effect of this embodiment are described below:

The camera 100 collects the rotation signal of the dial wheel 21 in a non-contact manner, which is beneficial to the modular closed space, and the flexible silicone ensures waterproofness when the dial wheel 21 is pressed, and provides reliable waterproof performance.

The non-contact sensor 3 is the application of the Hall effect: when the dial 21 rotates, the magnet on the dial 21 rotates with it, causing the magnetic field to change, and the Hall sensor 31 detects the change of the magnetic field and converts it into an electrical signal output, thereby detecting The position of the dial 21.

The non-contact signal acquisition facilitates the formation of a closed cavity between the dial assembly 2 and the non-contact sensor 3, and then uses the sealing principle to achieve waterproofing.

Most of the products on the market are single dial 21, modules without push buttons, and do not have waterproof performance. In this embodiment, a dial wheel 21 button is designed for the camera 100. In addition to the rotation function of the dial wheel 21, it also has the function of pressing the button (pressing the pulsator to realize the button triggering). The modular combination of the two and the use of flexible silicone, While it has better compatibility, it also has waterproof performance and can meet the requirements of IPX4-IPX7.

The triggering of the keys by the dial 21 may be translation (achieved by the cooperation of the slider and the chute) or swing. In this embodiment, the description is given in the form of swing. When the pressure is applied in the radial direction of the dial 21 (ie, the pressure is applied in the direction from the third opening 12 to the second opening 252 , that is, the pressure is applied in the direction of pressing the dial 21 into the camera body 1 ) ), the dial wheel 21 is forced to drive the inner shell 24 and the circuit board 23 to swing together around the second rotating shaft 247, and drive the trigger part 231 to touch the matching part 11 to realize the button trigger function.

The torsion spring 2811 is responsible for providing the preload force and the rebound force, and the tension spring 2812 plays the role of auxiliary adjustment. According to the actual use situation, one of the two can also be selected. By adjusting the compression amount and stiffness of the tension spring 2812/torsion spring 2811 and the idle stroke of the trigger portion 231, the adjustment of the pressing feel of the dial wheel 21 is realized.

When the dial wheel 21 is toggled, the dial wheel 21 rotates around the first rotating shaft 245 , the ring magnet on the dial wheel 21 rotates with the dial wheel 21 , and the motion signal is collected by the Hall sensor 31 on the circuit board 23 and converted into an electrical signal , trigger the toggle function.

Further, the spring in the guide groove 214 provides pre-tightening force, holding force and mechanical feedback feel, and the feel of the dial wheel 21 can be adjusted by adjusting the compression amount and stiffness of the spring in the guide groove 214 .

This solution eliminates the traditional physical buttons in the form of buttons on the dial wheel 21, so that the pressing feel is more user-friendly (there will be no multi-segment feeling of structure and buttons, and the pressing feeling can be adjusted according to needs). The feeling of the passage of the dial wheel 21 is achieved by the cooperation between the feel grooves 246 on the lower shell 2412 and the balls, and the structure of the feel grooves 246 in the present application is not limited.

To simplify the structure, the first rotating shaft 245 and the second rotating shaft 247 can be integrated with the lower shell 2412 (or the upper shell 2411 ) of the dial wheel 21 . The module integrates the functions of the dial 21 and the buttons, and can be installed in the required structure separately to realize modularization. When waterproofing is required, just adding flexible silicone can make the dial 21 module waterproof.

One side of the first waterproof member 271 is pressed by the waterproof pressing plate 272, and the other side is hoop on the inner shell 24, using the folds (free movement length) of the transition portion 2715 to realize the following action when swinging and realize waterproofing.

Of course, the above-mentioned embodiment can also be modified as follows:

The realization of the pressing function is not necessarily a swing type, but also a translation;

The material of the waterproof structure 27 is not necessarily only flexible silica gel, but can also be a dense material with certain elasticity, or some or some combinations thereof;

The combined form of the inner shell 24 and the outer shell 25 can also be changed, such as changing the upper shell 2411 and the lower shell 2412 into a front shell and a rear shell;

The non-contact signal acquisition does not necessarily use the Hall effect, but can also use other principles, such as the photoelectric effect.
