Description

A kind of notebook computer carriage

Technical field

The utility model belongs to notebook computer periphery annex, particularly relates to a kind of notebook computer carriage of placing notebook computer and being beneficial to heat radiation.

Background technology

At present, the notebook computer of selling on the market is only considered easy to carry, and does not use the operating personnel of notebook computer that design is provided for long-time.The visual angle of its screen, the height of keyboard and comfort level are all relatively poor, and only suitable operating personnel bow in the short time and manipulate, and are not suitable for being placed on the work top for a long time using; And the wind inlet of fan of notebook computer mostly is arranged on the bottom, and being placed directly in can influence the body heat radiation and then cause travelling speed to slow down on the work top.

Summary of the invention

In order to solve above-mentioned technical matters, the purpose of this utility model provides a kind ofly can adjust notebook computer screen height and visual angle easily and fast, improves comfort, is beneficial to the notebook computer carriage of heat radiation.

To achieve the above object, the utility model has adopted following technical scheme:

A kind of notebook computer carriage comprises supporting plate and seat board, and described supporting plate and seat board are hinged by at least two articulated elements; Described articulated elements comprises two fixed heads that are fixed on the seat board and is fixed on two plates under the supporting plate, two plates stretch in the middle of two fixed heads and by jointed shaft and are hinged, also be articulated with a ratchet in the middle of two plates, ratchet pawl head is interlockingly connected with the ratchet that is located on the plate lower circumference, and described ratchet is connected by elastic body with seat board; On the described plate jointed shaft, two plate intermediate sleeve are provided with a cam, the cam curve of cam is put together by a concentric little circular arc and an orthodrome, the radius of described little circular arc is less than the radius of plate bottom ratchet circumference, the radius of described orthodrome is greater than the radius of plate bottom ratchet circumference, described little circular arc is provided with a boss, described supporting plate bottom is provided with the button piece, and the button piece stretches between boss and the orthodrome.

Above-mentioned elastic body is one to be set in the torsion spring on the pawl pivot, and torsion spring one end and ratchet are interlockingly connected, and the torsion spring other end and seat board are interlockingly connected.

Above-mentioned supporting plate base is provided with barricade.

Above-mentioned supporting plate is provided with louvre.

Above-mentioned articulated elements is two.

The utility model has following advantage owing to adopted above technical scheme:

1. supporting plate and seat board are hinged by articulated elements, and articulated elements is that ratchet, ratchet one-way brake are hinged, and notebook computer is placed on the supporting plate, can make things convenient for the visual angle of the height and the display screen of rapid adjustment notebook computer, have also improved the computer comfort simultaneously;

2. louvre is set on supporting plate, has guaranteed the circulation of air of computer bottom, improved heat dispersion, travelling speed and the stability of notebook computer;

3. be provided with the cam that unidirectional hinged release resets in the articulated elements, can make things convenient for rapid adjustment supporting plate angle of inclination, do not need to increase unnecessary be locked action and parts;

4. in addition, also have simple in structurely, easy to carry, use advantages such as reliable, with low cost.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.

Embodiment 1:

A kind of notebook computer carriage as shown in Figure 1 comprises supporting plate 1 and seat board 2, and described supporting plate 1 is hinged by two articulated elements 3 with seat board 2, and supporting plate 1 base is provided with barricade 12, and supporting plate 1 is provided with louvre 11; As Fig. 2～articulated elements 3 shown in Figure 5, comprise two fixed heads 35 that are fixed on the seat board 2 and two plates 31 that are fixed under the supporting plate 1, two plates 31 stretch in the middle of two fixed heads 35 and by jointed shaft 39 and are hinged, also be articulated with a ratchet 36 in the middle of two plates 31 by pivot 40, ratchet 36 pawl heads and the ratchet 38 that is located on plate 31 lower circumference are interlockingly connected, and described ratchet 36 and seat board 2 are connected by elastic body; Above-mentioned elastic body is one to be set in the torsion spring 37 on ratchet 36 pivots 40, and torsion spring 37 1 ends and ratchet 36 are interlockingly connected, and torsion spring 37 other ends and seat board 2 are interlockingly connected; On described plate 31 jointed shafts 39, two plate 31 intermediate sleeve are provided with a cam 34, the cam curve of cam 34 is put together by a concentric little circular arc and an orthodrome, the radius of described little circular arc is less than the radius of plate 31 bottom ratchets 38 circumference, the radius of described orthodrome is greater than the radius of plate 31 bottom ratchets 38 circumference, described little circular arc is provided with a boss 32, described supporting plate 1 bottom is provided with button piece 33, button piece 33 stretches between boss 32 and the orthodrome, wherein, as shown in the figure, the arc chord angle of orthodrome is slightly less than 180 degree, and the circular arc angle of orthodrome and boss 32 is slightly less than 90 degree.
