Description
Technical field
The present invention relates to the articulated structure of LCD.Specifically, exactly about for reducing LCD in the space that carrying or keeping are occupied the time, and the LCD articulated structure that display can be placed in horizontal mode.
Background technology
Generally speaking, the LCD of computing machine is all attached articulated structure, thereby can make the main body of LCD with respect to bottom surface or support portion support displays.Simultaneously, can regulate the angle of inclination of display.
But, LCD with this articulated structure is when normal the use, though can carry out angular adjustment according to user's requirement, but, after product is made, cut in the process or at dress, when the main body of display is packed, become the horizontal shore of the main body of display of erectility and support displays main body to be in the orthogonal form generally and arrange handling processes such as it move.Like this, whole display product to occupy the space just bigger.Simultaneously, the volume of the packing of product is also bigger.This is its existing problem.
As shown in Figure 1a, in order to address the above problem, just provide a kind of articulated structure A that can carry out tilt adjustment.The angle of cutting or need regulate during carrying at dress when display has surpassed the tilt adjustment scope (X-line) when display normally uses, and promptly utilizes articulated structure that the display angle of inclination is adjusted to horizontality.
The structure of this articulated structure is shown in Fig. 1 b and Fig. 1 c, and it is made of following components: the display analog bracket Mb that is installed in LCD main body M back; Be installed in and be used for display unit main body is supported on bracing frame S on the base support means B of bottom surface; The hinge H that display analog bracket and bracing frame are coupled together and can rotate mutually; Be installed on the hinge, be used for limiting the angle of inclination adjusting backstopping assembly 10 at display angle of inclination; Be installed on the above-mentioned bracing frame S, regulate backstopping assembly 10 with above-mentioned angle of inclination and limit the tilt adjustment scope of display unit main body, and have the angle of inclination limiting part 20 of projection.
The square opening 10h that backstopping assembly 10 has the sweep that can insert hinge H is regulated at above-mentioned angle of inclination, and it can be rotated with hinge.Simultaneously, it has stop projection 15, it can with the anglec of rotation regulating device of display analog bracket Mb (not indicating on the figure) and above-mentioned inclination limiting part 20 interactive effects, and can only between two parts, move.Like this, just can in permissible angle of heel degree range of adjustment, regulate the angle of inclination that shows.
The angle of inclination limiting part 20 that the angle of inclination of display is regulated is parts of a crooked shape, it have by the planar portions of the fixed orifice 20h that bracing frame S is installed with become the upper board spring assembly 25 of vertical curve to constitute with this planar portions.Central part at laminated spring 25 forms its cross sectional shape teat 25a in the form of a truncated cone, stop projection 15 interactions of backstopping assembly 10 are regulated at it and above-mentioned angle of inclination, thereby can regulate the rotating range of backstopping assembly 10 to above-mentioned angle of inclination, promptly the range of tilt angles of display unit main body is carried out spacing.
In order in carrying or keeping process, display unit main body to be adjusted to the horizontal tilt state, the upper bend laminated spring 25 of above-mentioned angle of inclination limiting part 20 is made of resilient material, and the stop projection 15 that backstopping assembly is regulated at above-mentioned angle of inclination contacts with the outstanding position 25a of above-mentioned laminated spring device 20.When wanting the rotation of limit stops (, the angle of inclination range of adjustment when normally using), then apply extra strength and make backstopping assembly 10 rotations.Then, under the elastic force effect of the teat 25a of above-mentioned laminated spring device, stop projection 15 is by teat 25a.Like this, just the main body of display can be adjusted to the horizontal tilt state.
But, for the articulated structure of the LCD of this prior art, though itself have elasticity with the laminated spring device 25 of above-mentioned stop projection interactive effect.But when it continues to bear repeatedly load above certain limit, will certain deformation take place because of surpassing elastic limit, thereby the laminated spring device is suffered damage.And finally cause and to carry out tilt adjustment to display unit main body.
Summary of the invention
The object of the present invention is to provide a kind of not only can be to normal use the time degree of tilt of display unit main body regulate, also can carry out the LCD articulated structure of stable regulation simultaneously, thereby solve the problem that above-mentioned prior art produces the degree of tilt of the display unit main body in carrying or the keeping process.
To achieve these goals, LCD articulated structure according to the present invention is made of following components: the display analog bracket that is installed in LCD main body back; Display unit main body is supported on bracing frame on the bottom surface; The hinge that display analog bracket and bracing frame are coupled together and can rotate mutually; Be installed on the hinge, and have the angle of inclination adjusting backstopping assembly of the inhibition projection that can limit the display angle of inclination; Be installed on the above-mentioned bracing frame, regulate the angle of inclination limiting part that backstopping assembly limits the tilt adjustment scope of display unit main body with above-mentioned angle of inclination.Above-mentioned angle of inclination limiting part is made of following components: be installed in the 1st planar portions on the bracing frame; Have the elastic bending planar portions vertical, and regulate the elastic bending device that comprises central inclination teat of the stop projection interaction of backstopping assembly with above-mentioned angle of inclination with the 1st planar portions; Support the supporting projections of above-mentioned elastic bending device; Be installed in the 2nd planar portions on above-mentioned the 1st planar portions.
According to embodiments of the invention, the supporting projections of above-mentioned the 2nd planar portions has following feature: promptly it can distinguish two side planes of support elastic bending apparatus.
According to embodiments of the invention, the central teat of above-mentioned elastic bending device has following feature: promptly it has its cross sectional shape dip plane in the form of a truncated cone, and the stop projection of above-mentioned tilt adjustment backstopping assembly comprises a dip plane, contacts with the dip plane of teat when it is contacted with above-mentioned teat.As previously mentioned, the invention provides a kind of articulated structure that has that is used for LCD.When the angle of inclination of display unit main body is regulated; when particularly being adjusted to the horizontal tilt state for keeping or convenient in carrying and display unit main body; even restriction angle of inclination parts bear the load from the outside repeatedly; also can support by display unit main body according to articulated structure of the present invention; and provide sufficient protection, thereby make display unit main body keeping safety and convenient in carrying.Simultaneously, the packing area occupied in the time of can reducing keeping or carrying greatly.This is the good result that it has.
