Abstract
Description
Technical Field
[0001] This utility model relates to the field of induction cookers, and in particular to a touch structure applied to the control panel of an induction cooker. Background Technology
[0002] Currently, most induction cooker control panels on the market use spring-loaded touch buttons to achieve touch functionality. These spring buttons are typically mounted on the main circuit board, with a backlight source located below them. However, this structure has significant assembly and positioning problems: when assembling the circuit board with the spring buttons onto the underside of the induction cooker's microcrystalline glass panel, the physical position of the spring buttons is easily misaligned with the pre-printed function markings, such as gear indicators and function icons, on the bottom surface of the microcrystalline glass panel. This causes a mismatch between the user's actual touch position and the expected function area, resulting in touch sensitivity failure or false triggering. Simultaneously, the light emitted by the light source cannot accurately illuminate the corresponding function marking areas, causing backlight misalignment, uneven backlighting, or some function keys lacking backlighting altogether, severely impacting the user experience and the perceived quality of the product. Utility Model Content
[0003] The purpose of this invention is to provide a touch structure for use on the control panel of an induction cooker to solve the above-mentioned problems.
[0004] According to one aspect of the present invention, a touch structure for use in an induction cooker control panel is provided, comprising: a microcrystalline glass panel, a positioning bracket provided on the bottom surface of the microcrystalline glass panel, a first groove for accommodating a touch component being formed on the top of the positioning bracket, the upper surface of the touch component being attached to the bottom surface of the microcrystalline glass panel, and a second groove for accommodating a light source component being formed on the bottom of the positioning bracket; the touch component having a plurality of light-transmitting holes corresponding to the light source component.
[0005] In some embodiments, the touch component includes a flexible circuit board, the flexible circuit board including an insulating substrate layer and a conductive layer, the light-transmitting hole being formed in the insulating substrate layer, and the conductive layer being disposed at the edge of the light-transmitting hole.
[0006] In some embodiments, the insulating substrate layer is a polyimide or polyester film; the conductive layer is a copper foil.
[0007] In some embodiments, the conductive layer is formed on the insulating substrate layer by a printing process.
[0008] In some embodiments, the conductive layer is bonded to the insulating substrate layer using an epoxy resin adhesive.
[0009] In some embodiments, the second groove and the light source assembly are respectively provided with screw holes, and the light source assembly is fixed to the second groove by bolts.
[0010] In some embodiments, the edge of the second groove is provided with a plurality of elastic limiting buckles for defining the position of the light source assembly.
[0011] In some embodiments, the light source component is an LED lamp.
[0012] This invention, by setting a bracket with positioning function, precisely accommodates the touch component and the light source component in specific grooves at their top and bottom, respectively, and utilizes the light-transmitting holes on the touch component as sensing windows for function keys and backlight channels. This effectively overcomes the shortcomings of existing technologies and has the following significant advantages:
[0013] The positioning bracket serves as the core carrier, and the first and second grooves respectively physically limit and fix the touch component and the light source component, fundamentally ensuring that the touch sensing area (the position of the light-transmitting hole surrounded by the conductive layer), the light source illumination position and the functional marking print on the bottom surface of the microcrystalline glass panel are strictly aligned, completely solving the problem of touch misalignment and backlight offset caused by accumulated assembly tolerances.
[0014] Using a flexible circuit board with light-transmitting holes as the touch component eliminates the need for a traditional mechanical spring structure, simplifies the assembly process, reduces the risk of failure due to spring failure or displacement, and improves the overall reliability and lifespan of the system.
[0015] Users can precisely trigger the touch components below by touching the function label area of the microcrystalline glass panel, realizing "what you see is what you touch"; at the same time, the light from the light source component can accurately pass through the corresponding light-transmitting holes to illuminate the function labels, ensuring uniform, accurate and complete backlighting, which greatly improves the intuitiveness, convenience and visual experience of user operation.
[0016] The light source assembly can be securely and conveniently fixed to the positioning bracket by screws or elastic clips, facilitating assembly, disassembly, maintenance, and replacement. Attached Figure Description
