Abstract

The invention relates to a metal inductive touch device. The metal inductive touch device comprises a metal panel and is characterized in that an insulated isolation layer and a control circuit board in overlapped and fixed connection are arranged on the lower surface of the metal panel; a keystroke inductive area is arranged on the upper surface of the metal panel; a button pattern is arranged in the keystroke inductive area; a through hole is formed in the insulated isolation layer; the size and the shape of the through hole correspond to that of the button pattern; an inductive coil is arranged on the surface of the control circuit board; the diameter of the inductive coil is slightly less than that of the through hole; the inductive coil and the through hole are correspondingly arranged; and the surface of the control circuit board, where the inductive coil is arranged, is laminated with the insulated isolation layer, so that an integral metal inductive touch structure is formed. The metal inductive touch device disclosed by the invention has the benefits of being low in signal attenuation, few in false operation, high in environmental interference resistance, free from punching on the metal panel, simple in structure, convenient to process, attractive and wearable.

Description

technical field

[0001] The invention relates to a touch device, in particular to a metal induction touch device, which is suitable for an electric appliance controller. It belongs to the technical field of electric controller accessories. Background technique

[0002] Currently, touch buttons are widely used. Traditional touch buttons use mechanical buttons, and because the mechanical contacts are easily damaged and have a short service life, they have been gradually replaced by touch-sensitive buttons.

[0003] In the prior art, capacitive touch-sensing buttons are more commonly used. Its structure is that the touch panel is made of insulating material (such as plastic or glass), and the touch switch penetrates the touch panel of the insulating material to detect the touch action of human fingers. However, this capacitive touch key has the following problems: (1) Only non-conductive materials can be used as the manufacturing material of the touch panel, and non-conductive...

Examples

specific Embodiment 1

[0025] refer to figure 1 , figure 2 and image 3 , the present embodiment includes a metal panel 100, an insulating spacer 200 and a control circuit board 300 are provided on the lower surface of the metal panel 100, and a key sensing area 110 is provided on the upper surface of the metal panel 100. A button pattern 120 is set on the area 110; a through hole 210 is opened in the insulating isolation layer 200, and the size and shape of the through hole correspond to the button pattern 120; an induction coil 310 is arranged on the surface of the control circuit board 300, and the induction coil The diameter of 310 is slightly smaller than the diameter of the through hole 210, and the induction coil 310 is arranged corresponding to the through hole 210; the surface of the control circuit board 300 where the induction coil 310 is installed is attached to the insulating isolation layer 200 to form an integrated metal sensing touch structure.
