Description

Technical Field

[0001] This utility model relates to the field of remote control technology, and in particular to a wiring structure for a remote control with a touchpad. Background Technology

[0002] As an important control tool for home appliances, remote controls have evolved from traditional button-type to touchscreen-type. Traditional remote controls mainly consist of a casing, dome switches, conductive adhesive, and other components, using buttons for signal transmission and control. With technological advancements, users' functional demands for remote controls have become increasingly diverse, leading to the emergence of touchscreen remote controls.

[0003] Currently, touchscreen remote controls are widely used in the market. Chinese Patent Publication No. CN105306994A discloses a touchscreen remote control that achieves touch control functionality by connecting the touchscreen to the motherboard, greatly improving the user experience. However, in existing technologies, touchscreen remote controls typically use FPC cables to connect the touchscreen to the motherboard. The current wiring structure for FPC cables is relatively complex, increasing production difficulty and maintenance costs, resulting in a complex overall structure that is not conducive to production and assembly.

[0004] Based on this, in order to solve the above problems, we propose a wiring structure for a remote control with a touchpad. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as complex wiring that increases production difficulty and maintenance costs, by proposing a wiring structure for a remote control with a touchpad.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a remote control wiring structure with a touchpad, including a housing, a PCB board, a dome switch and conductive adhesive installed in the housing, and a receiving opening at the front end of the housing, wherein a touch unit is detachably connected inside the receiving opening;

[0008] The touch unit includes a touch panel, an adhesive backing, and a touch plate. The touch plate is electrically connected to the PCB board via an FPC line, and the housing has a routing channel for the FPC line to pass through.

[0009] Furthermore, the housing includes a front shell and a bottom shell;

[0010] A support portion for supporting the PCB board is formed in the bottom shell, wherein the inner side of the bottom shell has a snap-fit ​​portion, and the bottom of the top shell has a claw that snaps into the snap-fit ​​portion.

[0011] Furthermore, the PCB board, the dome switch, and the conductive adhesive each have a notch on their side, and the notch and the side of the bottom shell form the wiring channel.

[0012] The FPC line is bent along the trace channel in the middle and its two ends are connected to the ports of the PCB board and the touch panel, respectively.

[0013] Furthermore, the adhesive backing is located between the touch panel and the touch plate, wherein a fastening structure is also provided between the touch panel and the receiving opening.

[0014] Furthermore, the fastening structure includes elastic claws formed on both sides of the touch panel, the elastic claws having an L-shaped structure;

[0015] A snap-fit ​​notch is also provided on the inner side of the receiving opening, and the elastic claw deforms along the snap-fit ​​notch to enter and snap onto the inner side of the snap-fit ​​notch.

[0016] Furthermore, the faceplate has a protrusion and an inner bend at the receiving opening, the touch unit is placed on the inner bend, and the protrusion protrudes from the upper surface of the faceplate.

[0017] The present invention proposes a remote control wiring structure with a touch panel, which has the following advantages: Firstly, by bonding the touch panel to the touch shell with adhesive to form a whole, assembly is simple; the touch panel can be easily engaged by its elastic claws into the notches on the front shell, greatly improving assembly convenience. Secondly, the FPC cable cleverly bypasses the conductive adhesive sidewall, allowing sufficient pressing stroke for the touch panel ports, thus solving the problem of limited stacking space. Simultaneously, this design requires lengthening the FPC, addressing assembly difficulties on the production line and improving operational efficiency and production capacity.
