Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the embodiment of the utility model discloses a kind of pivoting mechanism, is used for connecting the display end and the system end of notebook computer, and this pivoting mechanism comprises rotating shaft 10, gear 30 and rotating shaft seat 20; One end is fixedly connected with the display end, and can rotate with the display end; the gear 30 is fixedly connected with the other end of the rotating shaft 10, and can rotate with the rotating shaft 10, so that when the display end rotates, the gear 30 can be driven to rotate; the rotating shaft seat 20 is fixedly connected to the The system end is also provided with a rack 221 meshed with the gear 30 , so that the rotating gear 30 can move linearly on the shaft seat 20 relative to the shaft seat 20 by meshing with the rack 221 .

As shown in Figure 2-Figure 5, when the notebook computer is opened, the angle between the display end and the system end increases continuously, and the display end drives the gear 30 to rotate clockwise through the shaft 10, and the gear 30 rotates clockwise At the same time, by meshing with the rack 221 on the rotating shaft seat 20, the gear 30 also moves away from the system end in a straight line, so that the display end can bypass the protrusion of the system end at the pivot joint, so that the display end and the system end are in the whole There is no interference during opening. During the fastening process of the notebook computer, the angle between the display end and the system end decreases continuously. The display end drives the gear 30 to rotate counterclockwise through the rotating shaft 10. The gear rack 221 meshes, and the gear 30 also makes a linear motion close to the system end. Finally, after the notebook computer is fully engaged, that is, when the angle between the display end and the system end is 0°, the gap between the display end and the system end at the pivot joint Reach the minimum, and the linear motion of the gear 30 close to the system end is the same track as the linear motion of the gear 30 away from the system end during the opening process of the notebook computer. Therefore, the display end can also bypass the protrusions without interfering with the system end.

In fact, during the opening and closing process of the notebook computer with the pivoting mechanism, the display end not only performs a rotational movement around the system end, but also performs a linear motion (that is, a translational motion) close to or away from the system end. The reason for the above-mentioned movement of the display end is that the gear 30 on the rotating shaft 10 is meshed with the rack 221 on the rotating shaft seat 20 for transmission. During the meshing transmission process between the gear 30 and the rack 221 , the gear 30 performs both rotational motion and linear motion (ie translational motion).

The gear 30 can be fixedly connected with the rotating shaft 10 in a variety of ways, such as integral molding, bonding and welding. In order to improve the maintainability and maintainability of the pivot structure of the present utility model, the In a preferred embodiment, the gear 30 and the shaft 10 are detachably connected. Specifically, the shaft 10 is integrally or welded with the shaft body 11 and the mandrel 12.

The rack 221 is arranged on the side of the stand 22 facing the base 21 , and the arrangement direction of the teeth on the rack 221 is perpendicular to the base 21 .

The display end of the notebook computer not only needs to rotate around the system end so as to adjust the opening angle, but also needs to keep the display end at this angle without free rotation after the angle is adjusted. For this reason, the pivot mechanism of the present invention A damping member and a damping structure are provided to prevent the display end from freely rotating. Specifically, a friction plate 50 is sheathed in the middle of the mandrel 12, and a first damping groove 222 is opened at the position where the stand 22 is opposite to the friction plate 50. The friction plate 50 partially extends into the first damping groove 222, and the first damping groove 222 is set so that its side can be in contact with the side of the friction plate 50 so that when the friction plate 50 rotates with the rotating shaft 10, it will generate friction with the first damping groove 222 to prevent the rotating shaft 10 from rotating, that is, damp the rotating shaft 10.

In this way, the movement of the rotating shaft 10 driving the gear 30 and the friction plate 50 in the direction away from or close to the base 21 (that is, away from or close to the system end) is not restricted, and the movement in the direction away from or close to the stand 22 is restricted. Therefore, the rotating shaft cover 40 can effectively prevent the gear 30 and the rack 221 from falling off, so that the gear 30 and the rack 221 mesh well. In this embodiment, a second damping groove 41 is defined at a position where the rotating shaft cover 40 is opposite to the friction plate 50 .
