Problems solved by technology

This kind of traditional computer keyboard is extremely poor in water resistance, as long as it enters water, the keyboard will not work normally, and will cause a short circuit or even damage to the circuit unit
[0004] There is an existing waterproof keyboard, which is mainly provided with a plurality of corresponding drainage pipe columns and perforations on the bottom surface of the upper cover and the bottom plate, and uses the drainage pipe columns to guide water into a liquid collection box provided on the bottom surface of the bottom plate, which can be used to prevent liquid leakage. Flow into the thin film circuit unit, but this design has a more complicated structure, and the drain pipe columns and perforations need to be arranged on the entire panel, which causes inconvenience in manufacturing, and the cost of the mold is higher, resulting in a much higher cost, and it cannot prevent water from entering 100% inside the keyboard

Embodiment 1

[0033] see Figure 1 ~ Figure 3 , a kind of waterproof computer keyboard 1 of the present invention, comprises button film 11, base 12 and the contact film 13 and thin film circuit unit 14 that are arranged between them, preferably also set up between thin film circuit unit 14 and base 12 A metal backing plate 15 with good rigidity makes the surface of the keyboard highly flat, with good hand feeling and uniform stress, while ensuring the rigidity and strength requirements of the keyboard. The signal wires of the thin film circuit unit 14 are led out of the keyboard through the wire hole 122 on the wire outlet cover 121 of the base 12, and the wire hole 122 is coated with sealant to prevent water and dust. The signal line can be connected to the computer host, so as to transmit the output signal of the keyboard 1 to the computer host.

[0034] see Figure 4 and Figure 5 , the button membrane 11 includes a radiation-permeable waterproof flexible sheet 111 and several button...

Embodiment 2

[0041] see Figure 9 and Figure 10 , a notebook computer 2 with a waterproof keyboard of the present invention includes a host 21 and a display screen 22 connected to each other, the host 21 is provided with a keyboard 3, the keyboard 3 includes a keypad 31, a base 32 fixed to the host 21 As well as the contact film 33 and the thin film circuit unit 34 disposed between the key film 31 and the base 32 , the peripheral edge of the key film 31 forms a sealing joint with the base 32 . The signal line of the thin film circuit unit 34 is connected to the main board inside the host 21, so as to transmit the output signal of the keyboard 3 to the host. The structure of the key membrane 31 is similar to the key membrane 11 in the waterproof computer keyboard 1 mentioned above. The structure and working principle of the thin film circuit unit 34 are similar to the thin film circuit unit 14 in the above waterproof computer keyboard 1 .

Abstract

The invention provides a waterproof computer keyboard and a laptop with the waterproof keyboard. The keyboard comprises a key-press film, a pedestal and a contact film and a film circuit unit arranged between the key-press film and the pedestal, wherein the key-press film comprises a radiation-transmitting waterproof flexible sheet and a plurality of key-press bodies formed on the front face of the waterproof flexible sheet by a radiation curing material through radiation curing; an ink layer displaying key-press characters is adhered to the back side of the waterproof flexible sheet; and a sealing joint is formed between the circumference of the key-press film and the pedestal. The waterproof computer keyboard can realize all-around waterproof, dustproof and antifouling effects and has simple structure and convenient assembly, thereby effectively increasing production efficiency and reducing production cost.

Description

technical field [0001] The invention relates to a computer keyboard with good waterproof performance, and also relates to a notebook computer with a waterproof keyboard. Background technique [0002] At present, with the advancement of technology, computers have gradually entered every company and family. The keyboard is an important device for the computer to receive information. If there is no keyboard, it is impossible to input data, and the computer cannot perform any work. [0003] The traditional computer keyboard consists of an upper cover, keys, rubber elastic body, film circuit unit, base and bottom plate, which are installed in sequence and locked by screws. The rubber elastic body is arranged between the key and the film circuit unit. The top of the touch pressing cap of the elastic body is in contact with the button. The thin film circuit unit has an extended wiring part, and the electrical contact of the wiring part is connected with a printed circuit board to ...
