technical field

The utility model relates to a hinge device, in particular to a hinge device which is convenient to be positioned at the front view angle of a user for shooting.

Background technique

In recent years, due to the vigorous development of network-related technologies, the network can be used to transmit text and sound, and has developed to the current technology that can transmit images simultaneously. Generally, the images are transmitted synchronously by installing network cameras. Network cameras are divided into external and built-in. Generally, network cameras used in notebook computers are mostly built-in in order to facilitate users to carry and avoid additional wiring. Cover end. In order to facilitate the user to adjust the shooting angle of the network camera, a hinge is provided between the network camera and the upper cover, so that the network camera can pivot relative to the upper cover. The hinge device in the prior art only provides that the network camera is positioned on a relatively parallel the angle of the cover. However, when using a notebook computer in general, due to the factors of distance and height, the best viewing angle of the top cover of the notebook computer is mostly not perpendicular to the base, but forms an angle greater than 90 degrees with the base. The web camera with the upper cover at a parallel angle cannot shoot the user from the front. At this time, if the web camera is pivoted to the angle of shooting the user from the front, it cannot be positioned and is easy to rotate, which causes inconvenience in use.

In the aforementioned pivot device, the two positioning protrusions of the male positioning block are opposite to each other by 180 degrees, and the two positioning grooves of the female positioning block are opposite to each other by 180 degrees.

In the aforementioned pivot device, the section of the pivot shaft is non-circular, and the section of the through hole of the concave positioning block and the fixing bracket is non-circular.

The aforementioned hinge, wherein the pivot is radially extended with respect to one end of the switch piece near the end edge to form a crown, the periphery of the crown protrudes a fan-shaped convex portion outward, and the rotation support extends toward the crown side relative to the pivot. A convex portion is formed, and the convex portion of the rotating support frame is relative to the fan-shaped convex portion of the pivot.

In the aforementioned hinge device, a ring groove is radially indented relative to one end of the fixed piece near the end edge of the pivot shaft, and the fixed piece is a C-shaped clasp fitted in the ring groove.

In the aforementioned pivot device, the periphery of the round hole of the rotating support frame is extended to form a through hole, and the convex positioning block is axially extended to form a clamping block relative to one side of the rotating support frame, and the clamping block is relatively fitted into the through hole of the rotating support frame.

In the aforementioned hinge device, the elastic component is a spring.

In the aforementioned pivot device, the pivot is riveted on the switch piece relative to the end of the switch piece.

The network camera is set in the preset groove at the end of the top cover of the notebook computer. The network camera and the rotating bracket are fixed to each other, and the top cover and the fixed bracket are fixed to each other. When the network camera rotates, it drives the rotating bracket and the convex positioning The block rotates relative to the pivot and the concave positioning block.

When the network camera rotates to the angle of shooting the user from the front, that is, when it forms an angle with the obliquely opened upper cover, the protrusion of the convex positioning block fits into the positioning groove of the fan-shaped groove of the concave positioning block to provide positioning Effect.

The utility model has the advantage that the width of the fan-shaped concave part of the concave positioning block is greater than the width of the positioning convex part of the convex positioning block, so as to increase the relative positioning angle range of the concave and convex positioning block, and the network camera can be relatively positioned on the upper side. Cover the shooting angle, and use the setting of the positioning slot to strengthen the angle of positioning the network camera at the front to shoot the user, and increase the convenience of use.
