The principle and effect of this embodiment are described below:
this camera 100 utilizes the non-contact mode to gather thumb wheel 21 rotation signal, is favorable to the modularization enclosure space, and waterproof when flexible silica gel guarantees to press down to dial the thumb wheel 21 provides reliable waterproof performance.
The contactless sensor 3 is an application to the hall effect: when the thumb wheel 21 rotates, the magnet on the thumb wheel 21 rotates to change the magnetic field, and the hall sensor 31 detects the change of the magnetic field and converts the change into an electric signal to be output, thereby detecting the position of the thumb wheel 21.
The non-contact signal acquisition is beneficial to the thumb wheel assembly 2 and the non-contact sensor 3 to form a closed cavity, and the waterproof effect is realized by utilizing the sealing principle.
The product on the market is mostly single thumb wheel 21, does not take the module of pressing the key, and does not possess waterproof performance. In the embodiment, a thumb wheel 21 key is designed for the camera 100, and the thumb wheel 21 key has a key pressing function (the push of the pulsator is used for triggering the key) besides a rotating function of the thumb wheel 21, and the thumb wheel and the soft silica gel are modularly combined and used, so that the waterproof performance is realized while the compatibility is better, and the requirements of IPX4-IPX7 can be met.
The triggering of the push button by the thumb wheel 21 can be translational (realized by the cooperation of the sliding block and the sliding groove) or swinging. In the present embodiment, the description is made in the form of a swing. When pressure is applied in the radial direction of the thumb wheel 21 (i.e. pressure is applied in the direction from the third opening 12 to the second opening 252, i.e. pressure is applied in the direction of pressing the thumb wheel 21 into the camera body 1), the thumb 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 the trigger portion 231 is driven to touch the matching portion 11, so as to realize the key triggering function.
The torsion spring 2811 is responsible for providing pretightening force and resilience force, and the tension spring 2812 plays a role in auxiliary adjustment. According to the actual use condition, the two can also be one. The adjustment of the pressing hand feeling of the thumb wheel 21 is realized by adjusting the compression amount and rigidity of the tension spring 2812/torsion spring 2811 and the idle stroke of the trigger 231.
When the dial wheel 21 is dialed, the dial wheel 21 rotates around the first rotating shaft 245, the annular magnet on the dial wheel 21 rotates along with the dial wheel 21, the hall sensor 31 on the circuit board 23 collects a motion signal, the motion signal is converted into an electric signal, and the dialing function is triggered.
Furthermore, the spring in the guide groove 214 provides pre-tightening force, holding force and mechanical feedback hand feeling, and the hand feeling adjustment of the toggle thumb wheel 21 can be realized by adjusting the compression amount and the rigidity of the spring in the guide groove 214.
According to the scheme, the traditional entity key is cancelled through the form of the key of the dial wheel 21, so that the pressing hand feeling is more humanized (the multi-section hand feeling of the structure and the key cannot occur, and the pressing hand feeling can be adjusted as required). The paragraph sense that the thumb wheel 21 toggles is realized through the cooperation of the hand feeling groove 246 on the lower shell 2412 and the balls, and the structure of the hand feeling groove 246 in the application is not limited.
For the sake of simplifying the structure, the first rotating shaft 245 and the second rotating shaft 247 may be integrated with the lower case 2412 (or the upper case 2411) of the jog dial 21. The module integrates the functions of the dial wheel 21 and the keys, and can be independently arranged in a required structure to realize modularization. In the occasion that needs waterproof, only need increase flexible silica gel can make thumb wheel 21 module possess waterproof performance.
One side of the first waterproof member 271 is pressed by the waterproof pressing plate 272, and the other side is hooped on the inner shell 24, so that the following action during swinging is realized by utilizing the wrinkles (free movement length) of the transition part 2715, and the waterproof effect is realized.
Of course, the above embodiment may be modified as follows:
the realization of the pressing function is not necessarily swing type, and can also be translational;
the waterproof structure 27 is not necessarily made of only flexible silica gel, but may be made of a dense material with certain elasticity, or a combination of one or more materials;
the combination of the inner shell 24 and the outer shell 25 may be changed, for example, the upper shell 2411 and the lower shell 2412 are changed 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.
