Description

Technical Field

[0001] The invention belongs to the technical field of touch panels, and in particular relates to a waterproof structure of a touch panel. Background Art

[0002] The touchpad module is an input device built into the keyboard of a laptop or tablet. It replaces the mouse to control the on-screen cursor and implement operations such as selection and clicking. A mechanical touchpad moves the PCB downward by pressing the cover. The dome on the PCB is deformed under force, and the internal pot piece conducts the circuit to realize the function. The touchpad needs to move up and down during the pressing process. Therefore, there will be a gap between the maximum size of the touchpad cover and the edge of the opening placement area of ​​the entire C-shell to prevent jamming and blocking when pressed.

[0003] Because there is a gap between the maximum size of the touchpad cover and the edge of the opening of the C-shell of the entire machine; if water, drinks or other liquids are accidentally spilled on the touchpad, the liquid will flow into the inside of the machine, damaging the electronic components and causing malfunctions; during long-term use, dust will also enter the machine through the gap. Long-term accumulation will increase the failure rate and shorten the product life cycle.

[0004] Therefore, a touch panel waterproof structure is needed to solve the dustproof and waterproof problems existing in the prior art.

[0008] It should be noted in the solution that the stainless steel bracket and the bottom piece are respectively provided with symmetrical first protrusion guides and second protrusion guides on the left and right sides, and the corresponding first protrusion guides and second protrusion guides are fixedly connected by screws.

[0009] It is worth mentioning that a positioning shaft is provided on one side of the upper end of each of the second protruding guides of the bottom piece, and the upper ends of the positioning shafts are all penetrated and slidably connected to the first protruding guides of the corresponding stainless steel brackets.

[0010] It should be further explained that a plurality of first card slots are provided on the front and rear sides of the stainless steel bracket, and a plurality of connecting members are symmetrically provided on the upper ends of the upper plastic bracket and the lower plastic bracket, and the plurality of connecting members are respectively fitted and slidably connected to the corresponding first card slots.

[0011] As a preferred embodiment, the lower plastic bracket is symmetrically fixed with a balance bar through a semicircular second slot, and the stainless steel bracket is assembled and fixed with the lower plastic bracket and the balance bar through a limiting buckle.

[0012] As a preferred embodiment, the lower end of the entire C-shell on the touch panel side is concave, and the stainless steel reinforcement plate has a raised heightened structure, and the stainless steel reinforcement plate and the entire C-shell are respectively affixed with a first waterproof foam or a second waterproof foam.

[0013] As a preferred embodiment, the first waterproof foam and the second waterproof foam are bonded and fixed with double-sided tape, and the surface of the stainless steel reinforcement plate is affixed with double-sided tape to be fixed to the lower plastic bracket.

[0014] Compared with the prior art, the touch panel waterproof structure provided by the present invention has at least the following beneficial effects:

[0015] This structure is achieved by enlarging the stainless steel reinforcement plate and creating a raised structure similar to a fence. Compressible waterproof foam is applied to the raised area, and the raised structure is extended into the C-shell of the entire device. A groove is opened at the corresponding position of the C-shell to prevent liquid from flowing in. At the same time, the same waterproof foam is applied to the connection between the C-shell and the stainless steel reinforcement plate, providing two layers of protection. Because the compressible foam material is used, the gap can be sealed by pre-pressing the foam without affecting the normal pressing feel of the touchpad. Because the material is soft, there will be no abnormal sound when pressing. BRIEF DESCRIPTION OF THE DRAWINGS
