Switching mechanism and electronic device thereof

Abstract

The present invention discloses a switching mechanism and an electronic device provided with the switching mechanism. The switching mechanism comprises a turn plate and a pressure sensing module, wherein the turn plate comprises a turn plate body, a shaft part and a contact part, the turn plate body is connected with the electronic device by the shaft part, and the contact part of which the bottom surface forms an oblique surface is arranged on the bottom of the turn plate body; the pressure sensing module is electrically fixed to the electronic device in a position below the turn plate, the pressure sensing module comprises a button part capable of moving up and down, and the button part keeps contact with the bottom surface of the contact part. When the turn plate rotates, the button part of the pressure sensing module can be pressed by the contact part, and different signals are output by the pressure sensing module according to the movement amount of the button part.

Description

technical field [0001] The present invention relates to a switching mechanism and an electronic device with the switching mechanism, more specifically, to a function switching mechanism applied to an electronic device with multiple functions. Background technique [0002] In the prior art, there are electronic devices (such as digital cameras) with switching mechanisms, and users can select desired operation functions (such as photographing mode, shooting mode, playback mode, etc.) by rotating a dial. [0003] In the switching mechanism of the electronic device in the prior art, a plurality of electrical contact switches (such as the Chinese Taiwan No. 584357 patent) are used mostly on the shrapnel on the turntable to contact the relative positions on the circuit board, and each electrical contact switch is respectively Corresponding to different functions, contact one of the electrical contact switches through the shrapnel to achieve multi-stage selection functions. Theref...

Problems solved by technology

[0004] However, when the number of selection functions to be achieved by the switching mechanism is large (such as 16-stage selection function), since the area under the turntable is the same, more electrical contact switches must be set, so the electrical contact switches must be made Smaller, which greatly increases the manufacturing cost of its components and increases the difficulty of assembly

[0005] In addition, since there is a gap between the electrical contact switches, when the user accidentally rotates the shrapnel of the turntable between adjacent electrical contact switches, the shrapnel does not touch any electrical contact switches, and the electronic device cannot Correctly judge the function selected by the user, so that the electronic device cannot be used normally
