The upper connecting member 11 is fixed to the rear case 2 of the display through the engagement between the engagement structure and the mounting groove.
Referring to FIG. 2, FIG. 5 and FIG. 6, FIG. 5 is a schematic view for illustrating a structure of the mounting groove in FIG. 3, and FIG. 6 is a schematic view for illustrating a structure after an engagement between the carrier frame and the mounting groove. In one example, the engagement structure includes a position limiting hole 111 provided at a predetermined position in the upper connecting member 11, a first protrusion portion 112 extending from a head of the upper connecting member 11 along a longitudinal direction of the upper connecting member 11, and a second protrusion portion 115 extending from an end part of the upper connecting member 11 along a lateral direction of the upper connecting member 11. Accordingly, the above-mentioned mounting groove comprises a first slot portion 24 accommodating the first protrusion portion 112 and being configured for matching with the first protrusion portion 112, a second slot portion 23 accommodating the second protrusion portion 115 and being configured for matching with the second protrusion portion 115, and an elastic sheet 21 configured for connecting with the position limiting hole 111 in an engagement manner when the upper connecting member 11 is inserted into the mounting groove.
In one example, the above-mentioned upper connecting member 11 includes a plate-like body having the position limiting hole 111, and there is no limitation on the shape of the position limiting hole 111. In one example, the longitudinal direction of the upper connecting member is the length direction of the plate-like body, and the lateral direction of the upper connecting member is perpendicular to the length direction of the plate-like body. In this case, the first protrusion portion 112 is extending from the head of the plate-like body along the length direction of the plate-like body, the structure of the first protrusion portion 112 is shown in FIG. 2, the second protrusion portion 115 is extending from the end part of the plate-like body along a direction perpendicular to the length direction of the plate-like body, and the structure of the second protrusion portion 115 is shown in FIG. 2. In one example, the mounting groove is a square-shaped groove, and the mounting groove comprises a first opening facing away from the display surface of the display and a second opening facing the ground, so as to facilitate to insert the upper connecting member 11 into the mounting groove, and thus to fix the support assembly with the rear case 2 in an engagement manner. An elastic sheet 21 is provided on the bottom surface of the mounting groove, a portion of the elastic sheet 21, which portion corresponds to the free end of the elastic sheet 21, for example, is of a convex platform structure for engaging with the position limiting hole 111. After the elastic sheet 21 is connected with the position limiting hole 111 in an engagement manner, the upper connecting member 11 can be prevented from retracting from the mounting groove, that is, the carrier frame 1 is prevented from moving upward and downward with respect to the rear case 2. In one example, the mounting groove includes a first slot portion 24 and a second slot portion 23. The first slot portion 24 is located in a first end surface 25, facing the ground, of the mounting groove, and the depth direction of the first slot portion 24 is perpendicular to the first end surface. The second slot portion 23 is located in the second opening of the mounting groove. When the upper connecting member 11 is inserted into the mounting groove, the upper connecting member 11 enters the mounting groove from the second opening and presses the elastic sheet 21 to deform so that the elastic sheet 21 contacts the bottom surface (the surface opposing to the first opening) of the mounting groove. After the first protrusion portion 112 is inserted into the first slot portion 24, lateral surfaces, inserted into the first slot portion 24, of the first protrusion portion 112, are respectively contact the first slot portion 24, that is, the first protrusion portion 112 matches with the first slot portion 24, meantime the elastic sheet 21 rebounds and is connected with the position limiting hole 111 in an engagement manner, and at the same time, the second protrusion portion 115 is inserted into the second slot portion 23 and matches with the second slot portion 23. Through the engagement between the first protrusion portion 112 and the first slot portion 24, the engagement between the position limiting hole 111 and the elastic sheet 21, and the engagement between the second protrusion portion 115 and the second slot portion 23, the upper connecting member 11 is restricted from moving in front and rear, upward and downward, leftward and rightward directions with respect to the rear case 2, that is, the upper connecting member 11 is fixed to the rear case 2 in an engagement manner. When it is required to detach the support assembly from the rear case 2, by pressing the free end of the elastic sheet 21 so that the elastic sheet 21 contacts the bottom surface of the mounting groove, the upper connecting member 11 can be retracted from the mounting groove, and the detachment is completed. Therefore, compared with the connection manner by fasteners, the detachability between the support assembly and the display is significantly improved.
Continuously referring to FIG. 2, in order to further improve the stability of the engagement between the upper connecting member 11 and the rear case 2, in one example, the above-mentioned engagement structure can further include two bending portions 113 respectively located at two sides of the upper connecting member 11 and bent to the lower connecting member 12. When the upper connecting member 11 is inserted into the mounting groove, two end surfaces, facing the first slot portion 24, of the two bending portion 113 respectively match with the end surface, facing the two bending portions 113, of the mounting groove, that is, contact the first end surfaces 25, facing the ground, of the mounting groove, and two lateral surfaces, facing the mounting groove, of the two bending portions 113 respectively match with two lateral surfaces, facing the two bending portions, of the mounting groove. In one example, as shown in FIG. 2 and FIG. 6, the end surfaces 114 of the bending portions contact the first end surface 25, facing the ground, of the mounting groove, the lateral surfaces, facing the mounting groove, of the bending portions contact the lateral surfaces 22 of the mounting groove, thus the upper connecting member 11 is further restrict from moving leftward and rightward with respect to the rear case 2, and hence the stability of the engagement between the upper connecting member 11 and the rear case 2 is further improved.
Referring to FIG. 7 and FIG. 8, FIG. 7 is a schematic view for illustrating a structure of the mounting groove having enforcement ribs, and FIG. 8 is a schematic view for illustrating a structure after the engagement between the support assembly and the mounting groove. In one example, the above-mentioned mounting groove is provided with a plurality of enforcement ribs on the two lateral surfaces and/or one end surface, and the two lateral surfaces and/or one end surface matches with the two bending portions 113. In one example, the two lateral surfaces of the mounting groove are respectively provided with a plurality of enforcement ribs 27. In one example, the first end surface 25 of the mounting groove facing the ground is provided with a plurality of enforcement ribs 26. By this design, even the upper connecting member 11 is inserted into the mounting groove many times, the mounting groove would not be damaged, that is, the service life of the mounting groove is prolonged, and in addition, it is also possible to improve the stability of the engagement between the upper connecting member 11 and the rear case 2.
Continuously referring to FIG. 2, in order to facilitate to apply an external force to the free end of the elastic sheet 21 so that the elastic sheet 21 contacts the bottom surface of the mounting groove to complete the detachment of the elastic sheet 21 from the position limiting hole 111, in one example, the free end of the elastic sheet 21 is provided with a concave portion 211 for facilitating to be pressed.
In the above embodiments, the support frame 3 is generally a support frame having a plurality of grid holes, when it is required to press the elastic sheet 21 to separate the elastic sheet 21 from the position limiting hole 111, the external force can be applied to the elastic sheet 21 through the grid holes. When the support frame 3 is a cylindrical support frame, the area, opposing to the position limiting hole 111, of the support frame 3 is provided with an operation window 31 configured for separating the elastic sheet 21 from the position limiting hole 111.
In summary, in the above support assembly, by using the engagement structure of the upper connecting member to fix the upper connecting member with the rear case of the display in an engagement manner, the support assembly can be firmly mounted on the rear case of the display. When it is required to detach the support assembly from the display, the detachment can be done only by separating the upper connecting member and the engagement structure from the rear case of the display. Therefore, compared with the fastening connection manner, the detachability between the support assembly and the display can be significantly improved.
In the accompanying drawings, only one example in which one support assembly is fixed to the back surface of the display in an engagement manner is shown. In another example of the present disclosure, one support assembly may include at least two carrier frames arranged side by side, each of the carrier frames includes a lower connecting member and an upper connecting member connected through a rotating shaft, the at least two carrier frames may support the same display or support different displays. Because they have the same operation principle as that shown in the accompanying drawings, detailed descriptions are omitted herein.
It is apparent to those skilled in the art to make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. In this way, if these modifications and variations belong to the scope of the claims of the present invention and their equivalents, then the present invention is intended to cover these modifications and variations.
