Abstract

The invention provides a waterproof keyboard used on casings of electronic products, which comprises a keyboard body and a support. The keyboard body includes elastic bodies and key caps on the elastic bodies, the support is provided with a keyboard body area and a non-keyboard-body area around the keyboard body area, a keyboard body is combined to the keyboard body area through the elastic bodies, the non-keyboard-body area is provided with enclosed ultrasonic wires around the keyboard body area, and the support is welded to the casings of electronic products by fusing the ultrasonic wires. The support is welded to the casings of electronic products ultrasonically for use, and the electronic products are completely separated at the keyboard body area both internally and externally, thereby having not only waterproof and antistatic functions, but simple manufacturing process.

Description

A kind of waterproff keyboard

Technical field

The present invention relates to a kind of keyboard, particularly a kind of waterproff keyboard.

Background technology

Keyboard is the necessary input equipment of a lot of electronic products, and it is one of most important parts of man-machine interaction.As input equipment, as the keyboard of electronic products such as mobile phone and laptop computer, because of exposing the outside at product usually, its keyboard especially should have the function of waterproof and antistatic, to avoid thus electronic product being produced destruction.

Waterproff keyboard with existing mobile phone is an example, and it generally comprises keycap and elastomer, and keycap and elastomer stick together.Be provided with a circle shirt rim around the elastomer, on handset shell, be provided with the muscle that a circle is pushed down the elastomer shirt rim,, reach sealing cell phone keyboard zone, obtain good waterproof effect so that elastomeric shirt rim is pressed onto on the pcb board.Thisly push down elastomeric encapsulating method by housing, can have micro gap unavoidably between keyboard and the pcb board, water or static can enter the mobile phone the inside from elastomeric gap, thereby its waterproof and anti-static effect are also good inadequately.

Summary of the invention

Embodiment of the invention technical problem to be solved is to provide a kind of technology simple, the keyboard that waterproof and anti-static effect are good.

The embodiment of the invention is to realize like this, a kind of waterproff keyboard, the housing that is used for electronic product, comprise keyboard body and support, keyboard body comprises elastomer and is positioned at keycap on the elastomer, support has the keyboard body zone and is positioned at keyboard body zone non-keyboard body region on every side, keyboard body passes through its elastomer-bonded in the keyboard body zone, the non-keyboard body region has around the ultrasound line of the sealing in keyboard body zone, and support passes through the ultrasound line molten solder on electronic product casing.

Technique scheme, owing to have around the ultrasound line of the sealing in keyboard body zone in the non-keyboard body region of support, support can be by the ultrasound line molten solder on electronic product casing.Like this, electronic product is inside and outside to be separated fully in the keyboard body zone, not only have good waterproof, electrostatic-proof function, and only need to reach the purpose of waterproof by ultrasonic bonding, a circle shirt rim need be set around elastomer, one circle is set on electronic product casing pushes down the muscle of elastomer shirt rim, so its manufacture craft is also simple relatively.

Embodiment

In order to make the technical problem to be solved in the present invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

Fig. 1 to Fig. 4 has shown a kind of waterproff keyboard, this is a preferred embodiment of the present invention, comprise keyboard body 1 and support 2, keyboard body 1 comprises elastomer 12 and is positioned at keycap 11 on the elastomer 12, support 2 has keyboard body zone 21 and is positioned at keyboard body zone 21 non-keyboard body region 22 on every side, and keyboard body 1 is incorporated in the keyboard body zone 21 by its elastomer 12.

This elastomer 12 has main body 121, and the upper surface of this main body 121 upwards stretches out a boss 122, and keycap 11 is adhered to the upper surface of boss 122.The lower surface middle part of main body 121 stretches out a projection 123 downwards, and the periphery of main body 121 then extends sidewall 124 in the form of a ring downwards, and the height of this sidewall 124 is higher than the height of projection 123.

Has through hole (among the figure not label) on this support 2, this through hole is used to hold the sidewall 124 of elastomer 12, and support 2 closes notes together with elastomer 12, and keycap 11 is adhered to the upper surface of the boss 122 that elastomer 12 has, like this, keyboard body 1 and support 2 are formed the whole A of a keyboard.Certainly, keycap 1 can also adopt other known method of this area to be fixed together with elastomer 2, support 3 with elastomer 2, for example does methods such as location assembling, extra quality injection moulding, can form the whole A of a keyboard as long as the three is fixed together.

The waterproff keyboard A of present embodiment is used for electronic product casing B, having of non-keyboard body region 22 around the ultrasound line 3 of the sealing in keyboard body zone 21, this ultrasound line 3 is positioned at the upper surface of support 2, support 2 by ultrasound line 3 molten solders on electronic product casing B relevant position (among the figure not label).The housing B of electronic product has the through hole 4 that donating bond disc main body 1 passes, and keyboard body 1 passes this through hole 4 and exposes keycap 11.Also can be provided with the excessive glue groove (not shown) of the ultrasound line 3 of accommodating fusing on the housing B relevant position of electronic product.Like this, electronic product is inside and outside to be separated fully in the keyboard body zone, therefore, not only have good waterproof, electrostatic-proof function, and only need to reach the purpose of waterproof by ultrasonic bonding, one circle shirt rim need be set around elastomer, the muscle that a circle is pushed down the elastomer shirt rim be set, on electronic product casing so its manufacture craft is also simple relatively.

Fig. 5 has shown the waterproff keyboard A ' of another preferred embodiment of the present invention, be used for electronic product casing B ', compare with the foregoing description, the difference of the two mainly is, in the present embodiment, in keyboard body zone 21 ', be provided with a plurality of keycaps (not indicating among the figure).

In the embodiment shown in fig. 5, it comprises keyboard body 1 ' and support 2 ' equally, support 2 ' has keyboard body zone 21 ' and is positioned at keyboard body zone 21 ' non-keyboard body region 22 ' on every side, keyboard body 1 ' is positioned at keyboard body zone 21 ', non-keyboard body region 22 ' has around the ultrasound line 3 ' of the sealing in keyboard body zone 21 ', and support 2 ' passes through ultrasound line 3 ' molten solder on electronic product casing B ' relevant position.Like this, electronic product is inside and outside to be separated equally fully in keyboard body zone 21 ', has good waterproof, electrostatic-proof function, and only needs can reach by ultrasonic bonding the purpose of waterproof, and its manufacture craft is simple.

In addition, as the embodiment of present invention further optimization, support 3 can adopt transparent material to make, and support 3 upper surfaces are installed the anti-dazzling screen (not shown).Like this, can reach the effect of leaded light, obtain uniform light efficiency.Transparent material can be a transparent material commonly used well known in the art, for example, and Merlon (PC), polymethacrylates (PMMA) etc.

The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
