Description

Anti-shake hinge with limit function

technical field

The utility model relates to an anti-shaking hinge device with a position-limiting function, in particular to a hinge device which can be arranged in an electronic device with a flip cover, so as to reduce the degree of shaking when the screen is opened and limit the opening of the screen. angle range.

Background technique

Due to its thinness, lightness, and small size, notebook computers can be carried around for document processing, presentations, and online operations in different places. Therefore, they have gradually replaced traditional desktop computers and are accepted by modern people who live in smaller and smaller living environments. When the screen of a notebook computer is turned on, since the distance from the pivot point to the free end of the screen is relatively long, the screen will shake. This shaking phenomenon will have a bad influence on the life of the hinge.

In order to reduce the occurrence of the above-mentioned phenomenon, the applicant of this case once proposed China Taiwan Patent Model Application No. 94208382 "fixed structure to prevent notebook computer screen from bouncing back and shaking", although it can reduce the problems caused by the above-mentioned existing notebook computer hub , but this kind of fixed structure does not have the function of limiting the opening angle range of the screen. In order to allow the opening angle of the screen to be in the best viewing range, the applicant in this case is not satisfied with the above-mentioned new case, and is still actively working on improvement , in order to provide more functional hubs.

Utility model content

The main purpose of this utility model is to provide an anti-shaking hinge with a position-limiting function, which can reduce the shaking phenomenon of the notebook computer screen when it is opened, limit the opening angle of the screen to the optimum range, and is more convenient to manufacture .

In order to achieve the above-mentioned creation purpose, the utility model adopts the following technical means to realize, wherein the utility model comprises:

A screen assembly sheet, which is combined with the screen, has a cylindrical assembly part on one side, and a clamping block is provided on the surface adjacent to the assembly part;

The body assembly piece, which is combined with the body, is provided with an insertion hole with a non-circular section on one side;

A pivot, one end of which is passed through the assembly part, and the other end is passed through the insertion hole;

The supporting sheet is arranged on the side of the clamping block of the screen assembly sheet and pressed against the screen assembly sheet, and has a perforation through which the pivot passes through and a fixing hole for the fastening block to be fastened. in:

The pivot is provided with a C-shaped limit ring block with an opening at the position between the relative support piece and the body assembly piece; the perforated outer edge of the support piece corresponds to the opening of the limit ring piece, and a concave shape The perforation is connected with the socket, and a limit block is riveted in the socket, and the limit block can move in the opening of the limit ring block and be stuck against the two ends of the opening to limit the pivoting angle of the screen assembly piece.

Through the mutual cooperation between the above-mentioned C-shaped limit ring block and the limit block, the screen can be opened and closed within the opening angle range of the C-shaped limit block, and the support piece is pressed against the screen assembly piece, which can provide A certain amount of friction can reduce screen shaking.

In addition, the above-mentioned limiting block is inserted into the socket, and is fixedly arranged by riveting, which makes the processing and manufacturing more convenient.

Detailed ways

Please refer to Fig. 1 and Fig. 2, the anti-shake and position-limiting hinge of the utility model includes a screen assembly piece 10, a body assembly piece 20, a pivot 30 and a support piece 40, wherein:

The screen assembly piece 10 is combined with the screen (not shown) of a clamshell electronic device, and a cylindrical assembly part 11 is arranged on one side, and a surface adjacent to the assembly part 11 is provided on the screen assembly sheet 10. A clamping block 12, and the clamping block is located away from the axis of the assembly part 11;

The body assembly piece 20 is combined with the body (not shown in the figure) of the clamshell electronic device, and one side thereof is provided with a semicircular insertion hole 21;

Pivot 30, one end of which is passed through the insertion hole 21 and has a semicircular cross-section, the other end is passed through the assembly part 11, and multiple oil grooves 31 are provided on it for coating and lubrication oil to improve the smoothness of the pivot; the pivot 30 is provided with a C-shaped stop ring block 32 with an opening 33 at a position between the relative support piece 40 and the body assembly piece 20;

The support piece 40, please refer to FIG. 3, is arranged on the side of the clamping block 12 of the screen assembly piece 10, and its surface is penetrated with a perforation 41 for the pivot 30 to pass through and corresponding to the shape of the assembly part 11, and for clamping. The fixing hole 42 buckled by the block 12; please refer to FIG. 4, the outer edge of the perforation 41 of the support piece 40 corresponds to the opening 33 of the limit ring block 32, and a recessed hole 41 communicates with the hole 41. mouth 44, and a limit block 43 is riveted in the socket 44, the limit block 43 can move in the opening 33 of the limit ring block 32 and be stuck against the two ends of the opening 33 to limit the pivot of the screen assembly piece 10. turn angle.
