Description

A kind of new waterproof keyboard

Technical field

The utility model relates to computer keyboard, relates in particular to a kind of mechanical keyboard with waterproof and dustproof function.

Background technology

Mechanical keyboard is modal computer entry device, it is widely used on microcomputer and various terminal device, computer operation person is by keyboard to the various instructions of computer input, data, and the work of command computer, is a kind of the most frequently used man-machine interaction mode.As everyone knows, water and dust are the natural enemies of electronic equipment, and perhaps everybody had such experience: because of carelessness the water tumbler being placed on desk has been done, then water spills into keyboard the inside, and then a lot of buttons on keyboard just cannot use.In addition, extraneous flying dust enters keyboard content and easily causes malfunctioning, the short circuit of operation, and how importantly cleaning even can become the infection sources of multiple infectious disease not in time, is as seen to the cleaning of keyboard.Because keyboard quantity is more, the side of complex structure, particularly each keycap, approaches the place of keycap bottom, more easily cleaning.

In order to solve above-mentioned deficiency, at present, also there is on the market the mechanical keyboard of some waterproof and dustproofs, but nearly all had technique and mechanism's complexity, production and processing difficulty is large, cost is high, and ponding is difficult for the problems such as discharge.

Utility model content

In order to overcome, there is structure and complex process in existing waterproof and dustproof keyboard, production and processing difficulty is large, cost is high, and ponding is difficult for the problems such as discharge; The purpose of this utility model is to provide a kind of novel keyboard.

According to an aspect of the present utility model; this practicality provides novel mechanical keyboard; comprise: keycap, upper cover, lower cover, mechanical switch, fixed head, electronics mainboard; the synthetic cavity of described upper and lower cover; in cavity, mechanical switch, electronics mainboard, fixed head form a communications component after being connected and fixed, and are coated with an outside protective covers at communications component.

The communications component that adopts the computer keyboard of technique scheme that the mechanical switch in cavity, electronics mainboard, fixed head are formed adopts waterproof material entirety to cover or parcel, water and dust cannot be entered in communications component, avoid communications component encroached on by it, reach waterproof and dustproof object.

In some embodiments; outside protective covers is that silastic material or tygon plastic film material make; the shape of outside protective covers and communications component form fit; make it be close to communications component surface; the movable contact of favourable like this and keycap and mechanical switch, silastic material or tygon plastic film material be not only easy to process and cost lower.

In some embodiments, for the water that infiltrates through keyboard is discharged in time, offer multiple leaking holes at lower cover.

In some embodiments; for keycap is better contacted with mechanical switch; on outside protective covers, be also provided with the balance columns in order to balance keycap; this balance columns can be that metal material is made; add man-hour and outside protective covers is one-body molded through Mould Machining, better ensured the sealing connecting between the two.

In some embodiments, according to the time needs of sealing, the top and bottom that outside protective covers can be wrapped up wholly or in part to communications component.

Compared to the prior art keyboard of the present utility model has: not only structure and manufacturing process are simple, long service life, be easy to the easily advantage such as discharge of ponding in processing and manufacturing and keyboard.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 to Fig. 6 has schematically shown a kind of new waterproof of the present utility model, dustproof keyboard.As depicted in figs. 1 and 2: existing mechanical keyboard comprises: keycap 1, upper cover 2, mechanical switch 3, fixed head 4, electronics mainboard 5 (PCB), lower cover 6, bucker 7, leaking hole, balance columns 9 form, keycap 1 is assemblied in 2 of upper covers and above contacts with mechanical switch 3 top movable, mechanical switch 3 is fixed on fixed head 4, and welding machine is on electronics mainboard 5, mechanical switch 3, fixed head 4, electronics mainboard 5 form a communications component A like this, and the input function of keyboard has mainly realized input computer by communications component A.Be positioned at keycap 1 below, in the cavity of upper cover 2 and lower cover 6 synthesizeds, communications component A covers or is enclosed with one deck outside protective covers 7, and water and dust cannot be entered in communications component A, avoids communications component encroached on by it, reaches waterproof and dustproof object.

Outside protective covers 7 makes for tygon plastic film material; the shape of outside protective covers 7 and communications component A form fit; make it be close to communications component surface, the movable contact of favourable like this and keycap 1 and mechanical switch 3, tygon plastic film material be not only easy to processing and cost lower.For the water that infiltrates through keyboard is discharged in time, offer multiple leaking holes at upper cover 2 or lower cover 6.For keycap 1 is better contacted with mechanical switch 3; the utility model is also provided with the balance columns 9 in order to balance keycap 1 on outside protective covers 7; this balance columns 9 can be that metal material is made; add man-hour and outside protective covers 7 is one-body molded through Mould Machining, better ensured the sealing connecting between the two.Water cannot enter communications component A inside from balance strip draw-in groove, realizes water proof and dust proof effect.Communications component A is assembled into a finished product keyboard by screw and the fastening assembling of upper cover 2, lower cover 6 by fastened by screw.

Can find out from diagram; mechanical switch 3 is fixed on fixed head 4 welding machine on electronics mainboard 5; mechanical switch 3, fixed head 4, electronics mainboard 5 form a protected outer cover 7 of communications component A and are wrapped in inside like this; thereby play dustproof and waterproof effect; ensure that keypad function is not damaged; protect the normal input of keyboard, greatly increased the serviceable life of mechanical keyboard, saved social resources.

Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
