Detailed ways

As shown in Figure 1, it is a schematic structural view of the notebook keyboard lifting device of the present invention. As can be seen from the figure, the notebook computer includes an upper casing 1 and a lower casing 2, which are used to connect the upper casing 1 and the lower casing 2 in rotation. The rotating shaft 3 and the keyboard 4 that is arranged on the lower casing 2 and can move relative to the lower casing 2, and the notebook keyboard lifting device includes: a link mechanism connected with the keyboard 4 and the rotating shaft 3 respectively, for rotating the rotating shaft 3 The active force is converted into an active force for changing the inclination angle of the keyboard 4 relative to the lower casing 2 .

When the notebook keyboard lifting device of the present utility model is set, two sets of link mechanisms can be set on the notebook, each set of link mechanisms is arranged on one side of the keyboard, and is connected with the keyboard and the rotating shaft respectively, so that when the user opens the notebook computer , the force of the rotation of the rotating shaft can be converted into the force of changing the inclination angle of the keyboard relative to the lower case, that is, the keyboard can be moved under the drive of the rotating shaft, and can be tilted upward at a certain angle relative to the lower case during movement, Thereby it is convenient for the user to have a suitable angle and use the keyboard better (as shown in Figure 3 and Figure 5); and when the notebook computer is closed, the keyboard will fall back under the drive of the rotating shaft, as shown in Figure 2 and Figure 4, Thereby it is convenient to carry the notebook.

Wherein, as shown in Fig. 2-Fig. 5, the connecting rod mechanism of the present invention includes: the rotating shaft connecting rod 5 hinged with the rotating shaft 3, which rotates under the drive of the rotating force of the rotating shaft 3; Connecting rod 6, which converts the rotating force of the rotating shaft connecting rod 5 into its moving force in the horizontal direction; the keyboard strut 7 connected to the middle connecting rod 6 at one end, and connected to the keyboard 4 at the other end; wherein, the keyboard The strut 7 converts the active force of the horizontal movement of the intermediate link 6 into the active force of the keyboard 4 moving up and down. When the rotating shaft rotates, the rotating shaft connecting rod rotates with the rotating shaft, and the intermediate connecting rod is driven by the rotating shaft connecting rod to produce displacement in the horizontal direction, that is, the rotating shaft connecting rod can pull or push the intermediate connecting rod, and the intermediate connecting rod can pull Or push the keyboard pole, so that the keyboard pole drives the keyboard to change the inclination angle relative to the lower casing.

Wherein, in order to make the intermediate connecting rod only move horizontally but not vertically under the drive of the rotating shaft connecting rod, the connecting rod mechanism also includes a connecting rod for constraining the intermediate connecting rod 6 to generate vertical displacement. The stopper and the horizontal guide for guiding the intermediate connecting rod 6 to move in the horizontal direction.

Wherein, the connecting rod limiting member is a limiting platform (not shown) that is arranged on the lower housing 2 and above the intermediate connecting rod 6, and its setting position can be determined according to the actual situation, and its function is to block the intermediate connecting rod, The intermediate link cannot move upwards vertically; and the horizontal guide is a chute (not shown) arranged on the lower housing 2, and the intermediate link 6 is slidably connected with the chute, and its function is to make the intermediate link move along the Move horizontally along the chute.

Further, as shown in Fig. 4 and Fig. 5, the linkage mechanism may also include a transition rod 7, which is arranged between the middle connecting rod 6 and the keyboard strut 8, and one end of which is hinged or fixed to the middle connecting rod Connected, the other end is hinged with the keyboard strut, when the intermediate link moves horizontally under the drive of the rotating shaft link, the transition bar also moves horizontally with the intermediate link, and drives the keyboard strut to move accordingly.

Further, in order to make the keyboard 4 rise and reach the limit position, the keyboard struts can support the keyboard, so that the keyboard will not fall freely when the user uses it, the linkage mechanism of the present invention also includes a position limiter 9 (as shown in FIG. 5), the position limiter can be arranged near the junction of the keyboard strut and the intermediate link. When the notebook is opened, the position limiter can increase the angle between the keyboard strut and the middle link, that is, the keyboard strut gradually props up the keyboard and one end of the keyboard rises; when the notebook is closed, the position The limiting member can reduce the angle between the keyboard strut and the intermediate link, that is, the keyboard strut drives the keyboard to fall back. Wherein, the position limiting member of the present invention can adopt parts or components in the prior art that can change the inclination angle between two hinged objects, and its structure will not be described here.

Preferably, in order to reduce the space, corresponding grooves that can accommodate the components of the linkage mechanism should be provided on the lower case. When the notebook is closed, the components can be placed in the grooves, so that the upper and lower cases of the notebook can Body can fit perfectly.

Although the utility model has been described in detail above, the utility model is not limited thereto, those skilled in the art can modify according to the principle of the utility model, therefore, all various modifications carried out according to the principle of the utility model It should be understood as falling within the protection scope of the present utility model.
