Description

A kind of portable computer

Technical field

The utility model relates to a kind of computer equipment of newtype, refers in particular to a kind of portable computer.

Background technology

From present present situation: though the popularity rate of computer and internet is quite high now, therefore traditional printed matter made of paper does not withdraw from the market, and is still keeping powerful growth momentum on the contrary.Compare with digitized books, the shortcoming of printed matter made of paper is fairly obvious.The first, waste is serious, and the production of printed matter made of paper and printing will consume a large amount of natural resourcess, and can cause great pollution to environment.Particularly resemble ageing very strong paper products such as newpapers and periodicals, magazine, office document, the reader is often read-only once just to be used as refuse and to throw into dustbin and gone, and this huge waste is the social concern that we must solve from now on.The second, carry and preserve inconvenience, the weight of printed matter made of paper is bigger.To reach about 5～15 kilograms as the school bag that present students in middle and primary schools carried on the back, will certainly give to carry and cause very big trouble; Moreover, for students in middle and primary schools, if things go on like this even can have influence on their healthy.And its preservation also is a very big problem, and a large amount of depositing of books need take a large amount of spaces.By contrast, just there are not the problems referred to above in digitized books substantially, and computer can store a large amount of books, next thousand books that the capacity of a compact disk just can be put.And there are not the notion of weight in digitized books, preserve and inquiry quite convenient.Can also revise arbitrarily and edit, and can play moving frame.All these advantages are that printed matter made of paper is incomparable at all.

Since the digitized book advantage is so obvious, still can't replace traditional printed matter made of paper why?

From this phenomenon, exactly illustrate that our existing computer product is perfect inadequately, they also exist certain deficiency in design, can not really address this problem.

And the reason that causes this situation mainly contains two: the firstth, and the computer popularity still is not high enough; The secondth, the mobile portability of computer has much room for improvement.Because costing an arm and a leg of computer can not allow everyone have the computer of oneself, people will obtain and shared information, also must rely on inexpensive paper products.And computer can not move, and can not can read for the people whenever and wherever possible as books.So have only when the computer price can be acceptable to all, just can become the commodity that everybody can both have, have only that to resemble books light and handy portable when computer, could really make printed matter made of paper eliminate out the stage of history.

Summary of the invention

Characteristics such as the purpose of this utility model is a kind of portable computer of design, and this computer has use with easy to carry, and memory capacity is big.

Its main technical schemes is that fuselage is made up of last down turnover cover, and LCDs is set on upturning lid, and keyboard is set on down turnover cover, and feature of the present utility model is to also have writing input board on down turnover cover.

The described down turnover cover of going up utilizes hinge to interconnect; On described fuselage, infrared interface is set; And audio output jack and microphone jack be set.

On described fuselage, USB interface should be set; Also the stylus jack can be set on fuselage as required; The built-in stylus that ejects perhaps is set.

The less liquid crystal display and the external power supply jack that are used for demonstration time, broadcast situation are set on fuselage.

The external pocket-pc of employing usually palm PC solves and carries inconvenience, little this problem of capacity, and the pocket-pc volume is very little very light.Can be placed in the pocket, and feature richness, be a kind of type that uses that is very suitable for moving.But because the pocket-pc volume is little, technological requirement is higher, so fetch long price, its close prices is in common desktop computer.And, also determined it to be unsuitable for carrying out a large amount of literal inputs because volume and display area are less.Also can limit reading because of effective area is little aspect reading, because people largely are with the mode of browsing when reading, and pocket-pc can't provide enough demonstration amounts, so not too meet people's reading habit.And storing also is a very big difficult problem, the flash flash memory of employing, and not only price height, and finite capacity is generally 64～256M.All these all are the inherent weakness of pocket-pc, are insurmountable.Therefore pocket-pc can only be as the utility appliance of computer, is the machine that uses when being fit to go out, and in use, the user of pocket-pc is computer of configuration in addition, so adopt the customer investment of this mode bigger.

Different with pocket-pc, portable computer provided by the utility model---we are referred to as PAD-PC and have possessed advantages such as cheap, practical and portable simultaneously.PAD-PC realizes these purposes by such design: at first, PAD-PC has adopted the overall dimensions bigger than pocket-pc, be one times of pocket-pc big (about long 200mm, wide by 140～170mm), adopted the design of flip-shell simultaneously.Adopting such size is for bigger space is provided on the one hand, and making design and produce can be masterly, and can adopt the many ready-made parts in many notebook computers.Thereby improve performance and reduce cost, operability is strengthened greatly.The upturning lid of PAD-PC is its display part, has comprised one 5～8 inches LCDs, is motherboard behind inner display screen.Down turnover cover is its operation part, has comprised the keyboard and the handwriting pad that aim at the PAD-PC design.There is hard disk inside, lithium battery, boombox, and motherboard.The internal memory of integrated processor, video, audio chip, 64M～128M on the motherboard of PAD-PC.Its processor host frequency remains about 1/3 (more than the 250MHZ) of notebook computer, design has several purposes like this: both can reduce cost, and go out to produce the CPU of low dominant frequency with existing technical matters, its thermal diffusivity, volume and power consumption all reduce greatly, and these all are to influence the important factor of removable computer performance.So this and the low dominant frequency CPU that produced in the past are not same notion.Hard disk adopt the notebook computer hard disk (5～10G), perhaps microdrive micro hard disk (1G).And hard disk is the most cheap on the present market, the storage medium of efficient and capacity maximum.From practicality, present desktop computer, the development priority of notebook computer are to improve machine performance, so the rate of metabolism of computer equipment is very fast.Basically just can finish the replacement of a generation in 6～12 months.Because PAD-PC is at the work higher to hardware requirement such as design effort and 3d gaming, and in the face of fields not high to the computer request for utilization such as business office, school eduaction, family's uses.Though CPU and display chip than high primary frequency have certain benefit to design effort and 3d gaming, when doing simple work such as word processing and multimedia application, the machine of its effect and low dominant frequency is without any difference.So because PAD-PC has adopted the relatively low technology of technology content, and the production equipment that can utilize production desktop computer of last generation, notebook computer accessory, therefore can drop to cost minimum.And this is just for popular, the universalness of PAD-PC are laid a good foundation from now on.

Such size had both satisfied the design needs of production run, satisfied lightly requirement easily in actual the use again.If too little, just can not hold any more hard disk and battery.Too big words just do not reach and move portable purpose, do not meet ergonomics.So in addition size is similar with general books, and PAD-PC also designs and the literal that laterally shows can be become specific function longitudinally, allows machine turn over to turn 90 degrees read, and as reading common book, meets very much people's reading habit.So adopting this size is the most reasonably to design.

From operating aspect, the design of flip-shell can flatly have a more button than what common pocket-pc used.The handwriting pad that PAD-PC adopts both can play input characters, can be used as mouse again, the touch screen function of this point and pocket-pc is close, but handwriting pad is very cheap, and can be as touch-screen, scuffing is caused to display screen in the long-term back of using, and is not only durable, can also change, this point is that touch-screen is not accomplished.And PAD-PC has nearly tens button, mainly includes function key and common key two classes, and common key has comprised numerical key, symbolic key, directionkeys etc.Function key then is to be button with function setting commonly used, and such as word processing, online, transmitting-receiving E-mail, telephone directory, media play, read a book, see picture etc., it is more succinct, convenient therefore to operate.The incomparable advantage of pocket-pc is arranged in word processing with when playing games.

PAD-PC is similar to notebook computer on the external form, but littler than notebook computer, approximately is its half, and the notebook front is about the A4 paper size, and PAD-PC is the A8 size.Both key distinctions be notebook computer towards be high-end user, and PAD-PC towards be medium and low-end users.Because notebook computer is by external design, the foreigner gets used to the keyboard input, and the size of keyboard is fixed, and therefore also defines the size of notebook computer.Since the notebook computer birth that Here it is, though speed of performance has improved tens times, and the volume external form changes very little reason.But still there is the defect that lays particular stress on bigger than normal in present notebook computer in actual the use.But keyboard also is not suitable for input in Chinese, and PAD-PC has adopted the mode of handwriting pad input then at Chinese custom.Be simple and easy to usefulness, need do not train, anyone can very fast left-hand seat.And the mode of handwriting pad input, being more suitable for moving use than the keyboard input, to make with the hands during the keyboard input, the handwriting pad input then can be finished by one hand, therefore can in all case use.The constraint on the notebook computer dimensions has been broken away from the employing that the most important thing is handwriting pad, can allow more exquisite that PAD-PC does.

The PAD-PC external interface comprises: external power supply jack, the USB mouth, audio output jack, microphone jack etc., its communication interface is a USB port, infrared port etc. can also be carried out the multiple network access way, comprising WLAN (wireless local area network) 802.11b, Bluetooth bluetooth and the wireless connections by the CDPD/GSM mode.

PAD-PC also joins a QWERTY keyboard in addition, includes power supply, network interface card, modulator-demodular unit.It uses when the stationary applica-tions for PAD-PC.Keyboard can allow the user who gets used to the keyboard input use, and power supply can be to PAD-PC power supply and charging.And network interface card, modulator-demodular unit are to allow PAD-PC connect regional network or go up the INTERNET net.

In addition, PAD-PC has also matched miniature stylus, establishes the stylus socket at upturning lid, external stylus, or adopt built-inly, and stylus is built in the upturning lid, in use with its ejection, and can allow stylus rotate in the horizontal direction.Adorning this stylus on PAD-PC, is a kind of very economical method, because stylus itself is very cheap, shooting work mainly is to rely on the computer powerful operation capacity, and the storage area.Therefore can become digital camera and digital gamma camera once, 200 yuan miniature stylus as long as join one.It is very strong to add the PAD-PC movability, just becomes real digital gamma camera.The PAD-PC that stylus has been installed can also do videophone, or teleconferencing.

PAD-PC is not provided with floppy drive and CD-ROM drive, is because present computer and network are more universal, adds PAD-PC and is convenient to move, so do not need to dispose these equipment again.Therefore install software has two kinds of methods, and the one, by common computer USB line install software on PAD-PC, the 2nd, download by INTERNET.And by all right mutual communication and exchange message between USB line or the infrared interface PAD-PC.

PAD-PC can adopt WINCE operating system on software, because support that now the software of WINCE is numerous, and the WINCE performance is more stable.PAD-PC also can support common WIN98 system.

The appearance that can predict PAD-PC will have influence on the general layout of whole PC market development.Because the development of PC all the time all is that technology is put at first, when the computer early stage of development, arithmetic speed were machine performance maximum bottleneck certainly, such strategy was correct.But, after particularly Pentium 2 processors occur, most of people can have been satisfied to the request for utilization of computer along with the computer technology develop rapidly.With P4 computer popular on the present market is example, is more suitable for design effort in fact and plays 3d gaming.But not all people does these work, therefore most of users may machine performance 50% all use less than, so not only cause the waste of resource, user's input is wasted.

So the development of computer also should have the classification of more refinement, to adapt to different consumers when the maintenance technology is constantly reformed.Practicability, hommization meeting are the important directions of computer development from now on.And PAD-PC is just meeting these requirements: the nature that its volume is littler, be easy to carry, met people's activity.Using but can be competent at fully as desktop computer, is a kind ofly can move use, can be used as the dual-purpose type that desktop computer uses again.Less expensive is easy to popularize simultaneously.And increased many utility functions, as study and amusement functions such as e-book, walkman, carry-on movie theatre, digital camera, gamma camera, carry-on game machines.

PAD-PC has drawn a circle to approve use colony according to its characteristics, is mainly the business office user, student user, women user.PAD-PC satisfies the mobile office of business office user needs, with online characteristics such as communicate by letter.Make the student enjoy multimedia teaching, and obtain the more knowledge amount.The project that also has women users such as being fit to OICQ, online chat to like.And, can also adjust its outward appearance according to different consumer group's hobbies, as increase button on outer turning cover, little liquid crystal display makes it to be more suitable for the user and play and listen to music when outdoor activity, can also show the time.Also removable shell etc. be can adopt in addition, external form more fashion and embodiment individual character made.Produce business office PAD-PC, series of products such as student PAD-PC, women PAD-PC.Finally allow computer become a kind of popular, practical household appliances.

Though PAD-PC is not too big breakthrough technically, just in external form and operation, improve, these seem simple improvement exactly, but make PAD-PC finish many problems that are difficult to solve in the past.Such as making paperless office become possibility, allow e-schoolbag replace traditional textbook, allow people can use computer whenever and wherever possible without restriction, not only can improve the efficient of office, study, also possessed E-BOOK, facsimile recorder, MP3 and broadcast machine, multiple functions such as movie theatre, portable hard drive, digital camera, gamma camera, vehicle-mounted computer, portable game with oneself, brought more enjoyment to people's work, life.And cooperate existing computer product with PAD-PC, and carry out performance to arrange in pairs or groups with the height in the configuration, more existing resource can be fully utilized, so PAD-PC is a product that has very much realistic meaning.
