Abstract

The utility model discloses a stacked structure for a center mainboard and a display screen in digital electronic equipment. A smooth board area without welding any electronic element is formed on one surface of the core mainboard; the display screen is stacked in the smooth board area; electronic elements are welded on the other surface opposite to the smooth board area; and electrical connectors are welded on the periphery of the smooth board area. According to the stacked structure for the center mainboard and the display screen in the digital electronic equipment, not any electronic element is welded in the stacked area of the core mainboard and the display screen, so that the physical height after the core mainboard is connected with the display screen is reduced, and the digital electronic equipment is in accordance with the development trends that the conventional portable electronic product is light, thin and small in size. In addition, the stacked structure is simple in structure and easy to implement.

Description

The stacked configuration of core mainboard and display screen in the digital electric equipment

Technical field

The utility model relates to a kind of digital electric equipment, especially relates to the stacked configuration of core mainboard and display screen in a kind of digital electric equipment.

Background technology

Digital electric equipment such as friendly code products of number such as handhold GPS, MP4, PDA, MID, is that life, amusement comprise the instrument that uses in the middle of the work, and its use is very universal.

(functional circuits such as integrated GPS, Digital Television and bluetooth on the core mainboard of handhold GPS) are present as an example of handhold GPS example, and the form that most of handhold GPS adopts two faces of core main circuit board all to be furnished with electronic component realizes these functions.

As shown in Figure 1, the two sides of core mainboard 1 is equipped with electronic component 2 and electrical connector 3, the display screen 4 of handhold GPS then directly be attached to core mainboard 1 wherein the one side electronic component on.There is following defective in the stacked configuration of existing core mainboard and display screen: have certain height owing to be welded on the electronic component 2 on core mainboard 1 surface, and highly inconsistent, so that core mainboard 1 with have larger physical thickness after display screen 4 is connected, take larger physical space, be unfavorable for physical size and the overall dimensions of handhold GPS are dwindled.

The utility model content

The utility model proposes the stacked configuration of core mainboard and display screen in a kind of digital electric equipment, do not weld any electronic component by the zone that core mainboard and display screen is superimposed, thereby reduce the physical height after the core mainboard superposes with display screen.

The utility model adopts following technical scheme to realize: the stacked configuration of core mainboard and display screen in a kind of digital electric equipment, a tabula rasa zone of not welding any electronic component is set on the wherein one side of described core mainboard, and described display screen connection is arranged on described tabula rasa zone.

Wherein, on the described core mainboard on the another side in relatively described tabula rasa zone welding some electronic components are set.

Wherein, the side welding in described tabula rasa zone arranges some electrical connectors.

Compared with prior art, the utlity model has following beneficial effect:

The utility model does not weld any electronic component by the zone that core mainboard just is connected with display screen, thereby reduce the core mainboard and the physical height after display screen is connected, make digital electric equipment meet that current portable electronic products is frivolous, the development trend of volume miniaturization.In addition, the utility model is simple in structure, realization is easy.

Fig. 3 is the Facad structure schematic diagram of core mainboard among the embodiment;

Fig. 4 is the reverse side structural representation of core mainboard among Fig. 3.

Embodiment

As shown in Figure 2, the utility model proposes the stacked configuration of core mainboard in a kind of digital electric equipment 1 and display screen 4, by any electronic component is not welded in the zone that is used on the core mainboard 1 being connected with display screen 4, and with electronic component 2 or electrical connector 3 be welded on core mainboard 1 not with lateral side regions that display screen 4 is connected on, thereby when display screen 4 attachings are connected on the core mainboard 1, the physical height after greatly reducing core mainboard 1 and display screen 3 being connected.

In conjunction with shown in Figure 3, in a preferred embodiment, the front of core mainboard 1 arranges a tabula rasa zone 11 of not welding any electronic component, with the reverse side (as shown in Figure 4) of welding electronic elements at core mainboard 1, and be that the electrical connectors 3 such as TF socket, supply socket, HDMI socket all are welded on tabula rasa zone 11 side or peripheral regions in addition; Display screen then overlays the tabula rasa zone 11 of core mainboard 1.

To sum up, the utility model does not weld any electronic component by the superimposed zone of core mainboard and display screen just, thereby reduce the physical height after the core mainboard superposes with display screen, make digital electric equipment meet that current portable electronic products is frivolous, the development trend of volume miniaturization.In addition, the utility model is simple in structure, realization is easy.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.　

Claims

1. the stacked configuration of core mainboard and display screen in the kind digital electric equipment is characterized in that, a tabula rasa zone of not welding any electronic component is set on the wherein one side of described core mainboard, and described display screen overlays described tabula rasa zone.

2. according to the stacked configuration of core mainboard and display screen in the described digital electric equipment of claim 1, it is characterized in that, weld on the another side in relatively described tabula rasa zone on the described core mainboard some electronic components are set.
