Abstract
The invention relates to an isolation type key which contains a button seat, a button lever shaft fixed clamping buckle, a buckle cover, a button spring, a button lever and an electronic control unit, wherein one end of the button lever is placed inside the button seat, and a permanent magnet is embedded inside the other end of the button lever. A magneto sensor is arranged on the electronic control unit, and the mechanical principle is used to enable the magneto sensor state of the electronic control unit to be changed, so that the electronic control unit is informed of carrying out corresponding operations. A button is not directly connected with the electronic unit in an electrical mode, so that the phenomena such as button failure caused by removing water vapor are avoided.
Description
Technical field
The present invention relates to a kind of button, particularly a kind of isolated form button.
Background technology
General electronic products and instrument and meter series products all are provided with button, common button is all that the electronic unit of direct and electronic product and instrument and meter series products directly adopts electrical connection, if be arranged on the electronic product outside by key contacts steam, thereby steam probably penetrates into inner electronic unit causes button malfunction, even affect the normal use of electronic product, the electronic control unit of button and electronic product adopts electrical connection, run into large voltage, heavy current impact or malicious sabotage, also can damage button and electronic product.
The invention provides a kind of isolated form button, button and electronic control unit are kept apart, and directly do not adopt electrical connection, thereby have stopped key part because the drawback that contact influence of moisture button uses.
Summary of the invention
The purpose of this invention is to provide a kind of isolated form button, the design of this press-key structure makes key part and electronic control unit keep apart, thus stop button because of and electronic unit adopt electrical connection, the phenomenon of the button malfunction that key part contact steam causes.
To achieve these goals, technical scheme of the present invention is as described below:
A kind of isolated form button, contain key base, button lever shaft fixedly buckle, button cap, by key spring, button lever, electronic control unit, it is characterized in that: button lever one end is placed in key base, the button lever other end is embedded with permanent magnet; Electronic control unit is provided with magneto sensor, and the button spring fitting is in key base; The button lever is provided with lever shaft; Lever shaft is stuck in the button lever shaft fixedly in buckle, and button cap adopts Elastic buckle to be connected with key base.
The invention has the beneficial effects as follows:
(1) button of the present invention directly with the electronic unit electrical connection, but adopt theory of mechanics to make the magneto sensor state of electronic control unit change to inform electronics electronic control unit execution corresponding operating.
(2) the present invention because button directly is not electrically connected with electronic control unit, has avoided causing by key contacts external humidification environment, steam the drawback of button malfunction.
Description of drawings
Accompanying drawing 1 is patent structure schematic diagram of the present invention.
Embodiment
Below in conjunction with description of drawings and embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1: a kind of isolated form button, fixedly key spring, (3) button lever, (1) electronic control unit are pressed in buckle, (7) button cap, (5) to contain (6) key base, (8) button lever shaft, it is characterized in that: button lever one end is placed in key base, the button lever other end is embedded with permanent magnet (4), electronic control unit is provided with magneto sensor (2), and the button spring fitting is in key base; The button lever is provided with lever shaft; Lever shaft is stuck in the button lever shaft fixedly in buckle, and button cap adopts Elastic buckle to be connected with key base.
Assembling process of the present invention and operation principle are as described below:
at first will be placed in key base by key spring, an end that again the button lever is not embedded permanent magnet is placed in key base, lever shaft on the button lever is stuck in the button lever shaft fixedly in buckle, at last button cap is stuck in the Elastic buckle of key base, so far, patent assembling of the present invention is complete, its operation principle is: when needing to trigger button, cap pushes button, due to lever principle, button lever one end that is embedded with permanent magnet also contacts with electronic control unit is close, the magnetosensitive original paper adhesive of electronic control unit, when in electronic control unit, central processing unit receives the signal of magneto sensor adhesive, central processing unit will be carried out corresponding operating.
The electronic product of using the present invention's manufacturing at electronic applications also should be within protection scope of the present invention.
Claims (1)
1. isolated form button, contain key base, button lever shaft fixedly buckle, button cap, by key spring, button lever, electronic control unit, it is characterized in that: button lever one end is placed in key base, the button lever other end is embedded with permanent magnet; Electronic control unit is provided with magneto sensor, and the button spring fitting is in key base; The button lever is provided with lever shaft; Lever shaft is stuck in the button lever shaft fixedly in buckle, and button cap adopts Elastic buckle to be connected with key base.
