Abstract

A laptop structure having members which are easy to dissipate heat among the laptop composing members disposed on the back side of the display, such as main board, CPU, heat dissipation module, memory module, and hard disk; members which hardly or do not dissipate heat disposed in the base portion of the host machine, such as battery, CD driver, PCMCIA card, NEWCARD, and external interface under keyboard. Since the heat dissipation members are disposed at the back side of the display, the heat dissipated from the base portion of the host machine is a lot less, so users can leisurely place the laptop on their laps. Meanwhile, there is larger space for inhaling fresh air and dissipating heat, which facilitates heat dissipation of the laptop. In addition, the main board is disposed on the back side of the display, so that the connection of the video card and display can be directly implemented by plug-and-socket other than by wire line, thereby achieving shorter distance and higher reliability.

Description

A kind of notebook computer structure

Technical field

The utility model relates to a kind of notebook computer structure.

Background technology

The general structure of existing notebook computer is that CPU, internal memory, hard disk all are placed on below the keyboard, places between main frame base upper surface and the bottom surface, and mainly is the placement display screen with part that the main frame base is connected by rotating shaft.The heat radiation of this existing structure is a problem, especially in moving use, if the user is positioned over computer on knee and the leg, then feel uncomfortable because of the hot user of making of the heat radiation of computer bottom surface, improving constantly particularly along with CPU and chip performance, power consumption is also increasing, and this problem is also more and more serious.Under the common operating position,, also must raise host machine part in order to guarantee the computer heat radiation effect, in order to avoid stop up through hole, so existing this structure especially be afraid of to be placed on soft sofa or spreading on the bed of soft cotton-padded mattress because extremely unfavorable to heat radiation.

Flat notebook computer also has similar problem.Therefore, existing structure causes the use of present notebook computer to be actually " portable desktop computer ", rather than real " kneetop computer (LAPTOP) ", neither mobile model computer (MOBILE PC), therefore notebook computer is at desk in the overwhelming majority time,, use on the estrade, only can be combined in display on the main frame more easy to carry.

The V of Sony of the prior art (SONY) series desktop computer handlebar CPU, hard disk are placed on the design of display screen back, but also do not see similar design on laptop.Model be VGC-M70/W desktop computer also radiating element such as handlebar CPU be positioned over the back of display screen, keyboard can be dug, make volume less, other display screen partly has special feet to support whole main frame to add display screen, but its volume is still light and handy not as notebook computer, therefore can not be in above-knee use; Being connected of its keyboard and main frame is not hard connection, and whole main frame is partly finished by the spike pad under the main frame, therefore can only use on desk.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of notebook computer structure is provided.

The display screen back that notebook computer structure of the present utility model is included in notebook computer settle to constitute the device of the easy heating in the device of notebook computer, as mainboard, CPU, heat radiation module, internal memory module and hard disk, arrangement is generated heat less or athermic device in the main frame base of notebook computer, as is installed in battery, CD-ROM drive, pcmcia card, NEWCARD and external interface below the keyboard.

Its benefit is, all radiating elements all are positioned over the back of display, heat radiation below the main frame base seldom, the user can be placed on notebook on the knee thigh at leisure and use like this, simultaneously, the parts of heating all are placed on the display back, bigger suction fresh air and bigger heat-dissipating space are arranged, help the heat radiation of notebook system more.

Other benefit is that motherboard is positioned at the display screen back, and being connected of video card and display screen can directly adopt connector to connect without cable, and distance is shorter, more reliable.

In addition, notebook computer structure of the present utility model also is included in the louvre of the two sides setting of notebook computer display screen.

In order to solve the counterweight problem, in notebook computer structure of the present utility model, devices such as the CPU that weight is bigger in the display screen behind, heat radiation module and hard disk are arranged on the place near the rotating shaft between display screen and the main frame base.The device that weight is bigger in the main frame base is arranged on the place away from the rotating shaft between display screen and the main frame base.

Embodiment

Below in conjunction with specific embodiment shown in the drawings the utility model is described further.

Fig. 1 to 5 shows an embodiment of notebook computer structure of the present utility model.Shown in the synoptic diagram of Fig. 1, this notebook computer structure comprises a display screen 1 and a main frame base 2.In the space, back of display screen 1, settled the device of heating (simultaneously referring to Fig. 2) easily such as mainboard 3, internal memory module 15, heat radiation module 4 and hard disk 22.In main frame base 2, be positioned at external interfaces such as having settled battery (electric battery) 7, CD-ROM drive 6, pcmcia card, NEWCARD, usb 14, infrared interface 16, audio interface 17 below keyboard 9 and the Trackpad 8 and mobile phone cabin or mouse cabin 18 (simultaneously referring to Fig. 3 and Fig. 4).

Therefore above-mentioned heater members is placed into the display screen back, some problems of counterweight can occur, will be placed into device heavier in the parts that remain in the main frame base 2 from the distant place of display screen rotating shaft 5.Wherein battery (electric battery) 7 for example adopts four groups of barrel-shaped batteries, is placed on Trackpad 8 belows, also is the requirement of counterweight.Adopt the design of independent video card, in it and directly adopt the connector connection being connected of display screen 1, easier for installation, being connected of battery 7 and host machine part utilizes rotating shaft 5 to come electric energy transmitting.

Reduce the line on the intermediate rotary shaft in the design, keyboard 9, Trackpad 8 and CD-ROM drive 6 all adopt USB interface as far as possible, and loudspeaker, LID also are reverse design, and button also designs in display screen side.Simultaneously in order to solve the counterweight problem, the counterweight of also being correlated with on display screen 1 is handled, the parts of weight maximum, such as CPU, heat radiation module 4, hard disk 22 grades are placed on the place of as far as possible close rotating shaft 5, and light parts are placed on the top, as shown in Figure 2, wherein hard disk 22 and heat radiation module 4 can transpositions.Because display screen 1 often is in the state of stirring, therefore need strengthen protection, to the shockproof processing of hard disk to hard disk 22.

As shown in Figure 3, be provided with louvre 11 in the two sides of notebook computer display screen 1, the shape of louvre 11 can be rectangle, ellipse (referring to Fig. 5) or other suitable shape.

Aspect being provided with of louvre, because there is the operation of user's hand the top of display screen 1, the below outlet can aim at the knee of human body, therefore all is not suitable for placing air outlet, therefore air outlet is set to the both sides of display screen.And the display screen surface of notebook computer after closing is the important image segment of notebook, therefore is unfit to do too many perforate, is consistent and complete as far as possible.

As Fig. 1, Fig. 3 and shown in Figure 4, on the two sides of notebook computer display screen 1, except being provided with louvre 11, also have video card connector 10, switch 13, external VGA 12, network interface and outlet 20 etc.
