SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a rotating shaft keyboard with a waterproof function.

The touch screen display panel comprises a shell, wherein a key core, a main PCB, a touch control assembly and an iron plate are arranged in the shell, the bottom of the iron plate is bonded with one surface of the main PCB through waterproof glue, the other surface of the main PCB is connected with a Mylar film, and a waterproof layer is arranged outside the Mylar film;

the casing is including the upper cover and the lower cover that close mutually, the lower cover corresponds main PCB board department and is equipped with the round rib position that absorbs water.

As a preferred mode, the water-resisting layer and the water-absorbing rib are made of waterproof foam.

As a preferable mode, the main PCB is bonded to the iron plate by 3M glue.

As a preferable mode, the area of the water-resisting layer is larger than the areas of the main PCB board and the mylar sheet.

Preferably, the Mylar film is made of a soft material and has a thickness of 0.001 MM to 0.1 MM.

As a preferred mode, the main PCB is further electrically connected with a membrane cable, a Pogo pin cable, and a TP Module cable.

As a preferred mode, one side of casing is equipped with the pivot subassembly, the pivot subassembly includes Pogo bar protecgulum, Pogo bar reinforcement spare, Pogo pin PCB board, Pogo bar magnet, Pogo bar back cover and pivot.

According to the rotating shaft keyboard with the waterproof function, one surface of the main PCB is bonded to the iron plate to be waterproof and isolated, the other surface of the main PCB is firstly bonded with the waterproof mylar sheet, the waterproof mylar sheet is further bonded with the waterproof foam, when water flows enter from the joint of the upper cover and the lower cover, the water flows are isolated above the main PCB, the waterproof mylar sheet at the lower part protects the water flows, the waterproof foam is blocked outside the mylar sheet, and the water flows in the keyboard can be prevented from flowing around and affecting other power supply devices. Secondly, the lower cover corresponds the position design round rib position that absorbs water, and the main PCB board of further ensuring is avoided intaking and is damaged, and the water accessible that each water-absorbing water barrier stored in is air-dried, is dismantled the upper and lower cover and dries or change all can. Compared with a traditional keyboard waterproof structure, the keyboard waterproof structure is simple in structure, lower in cost and convenient to replace and maintain.

Detailed Description

This keyboard mainly comprises upper cover 6, lower cover 7, key core 1, support iron plate 3, TP touch pad, left balancing weight, right balancing weight, PCBA mainboard, waterproof wheat draws, waterproof bubble cotton, magnet, pivot, Pogo bar subassembly etc. and improves to the structural design who does not have the waterproof dispensing groove of PCBA. The present invention will be described in further detail with reference to the following examples and drawings.

A rotating shaft keyboard with a waterproof function comprises a shell, wherein a key core 1, a main PCB 2, a touch control assembly and an iron plate 3 are arranged in the shell, the bottom of the iron plate 3 is bonded with one surface of the main PCB 2 through waterproof glue, the other surface of the main PCB 2 is connected with a Mylar film 5, and a waterproof layer 4 is arranged outside the Mylar film 5; the main PCB 2 is bonded with the iron plate 3 through 3M glue, and when water flows to the main PCB 2 from the holes corresponding to the key cores 1 through the left side and the right side of the iron plate 3, the 3M glue is attached to the supporting plate. Then, the outer surface of the main PCB 2 is provided with a special waterproof mylar, and waterproof foam is attached to the edge of the main PCB to block the direction of water flow and make isolation through sufficient compression of the foam.
