Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1 to 3.
The embodiment provides a display device, which comprises a display screen 10, a fixed support 20 and a labor-saving bending lifting bracket assembly. Wherein laborsaving lift bracket component that bends includes erection support 31 and the linkage structure that bends.
Specifically, the bending linkage structure can be switched between a straightened state and a bent state. Fig. 1 and 2 each show a bent state, and the maximum bending angle thereof may be set as desired. Fig. 3 shows a straightened state. As can be seen from fig. 1 to 3, as the bent state and the straightened state are switched, the height of the display screen 10 is changed, and the distance between the display screen 10 and the user is also changed.
Further, one end of the bending linkage mechanism 30 is fixedly connected to the fixing support 20, and the other end is hinged to a mounting support 31 for mounting the display screen 10.
The range of the rotation angle of the mounting support 31 can be set to 0-180 °. It should be understood that the rotation of the mounting bracket 31 may include the turning of the mounting bracket 31 in the up-down direction and the rotation in the left-right direction. In the present embodiment, the rotation of the mount bracket 31 includes only the turning in the up-down direction.
The straightening state and the bending state of the bending linkage structure can be realized through various structures. This example presents one of the alternative implementations. As shown in fig. 4.
The bending linkage 30 includes a first set of gear linkages and a second set of gear linkages. The first group of gear linkage pieces comprise a plurality of first gear linkage pieces 32 which are sequentially meshed and connected, and two ends of each first group of gear linkage pieces are respectively connected with the fixed support 20 and the mounting support 31.
The second group of gear linkage members comprise a plurality of second gear linkage plates 33 which are sequentially meshed and connected, and a mandrel 39 is arranged through the first gear linkage plates 32 and the second gear linkage plates 33.
Therefore, during the bending process, the first gear linkage piece 32 is bent and rotated, so that the second gear linkage piece 33 is driven to be bent and rotated by the action of the mandrel 39.
In order to limit the maximum angle of bending and prevent the display screen 10 from being damaged by impact, the first gear link plate 32 and the second gear link plate 33 are each provided with a predetermined number of teeth for meshing connection, as shown in fig. 5 and 6.
Therefore, when the state is switched to the straightened state, the number of teeth is constant as shown by the arrow in fig. 5, and the bending link mechanism 30 is restricted, thereby preventing the reverse bending. When the bending state is switched, as shown by an arrow in fig. 6, the bending link mechanism 30 is limited due to the fixed number of teeth, thereby preventing an excessively large bending angle.
The display device that this embodiment provided, through laborsaving lifting support subassembly of bending, can adjust the height of display screen 10 and adjust the distance between display screen 10 and the user to through the angle of watching of rotatory erection support 31 adjustment display screen 10, thereby solve the technical problem that exists among the prior art, improve user's experience.
Referring to fig. 4 and 7, in another embodiment of the present application, a first concave-convex structure 37 and an elastic member 36 are sleeved on a mandrel 39, and the first concave-convex structure 37 is in interference fit with the mandrel 39 and can slide along an axial direction of the mandrel 39. The second gear linkage plate 33 is provided with a second concave-convex structure which cooperates with the first concave-convex structure 37 to form a concave-convex wheel structure. Optionally, a flat washer 35 and nut 34 are sleeved on the mandrel 39. Alternatively, the elastic member 36 is a compression spring. Optionally, a decorative plate 38 is provided on one side of the second gear linkage plate 33. The first relief structure 37 is one of a concave wheel and a cam, and the second relief structure is the other of the concave wheel and the cam. In this embodiment, the first concave-convex structure 37 is a cam, and the second concave-convex structure is a concave wheel.
The elastic member 36 is always in a compressed state, and when the bent state is switched from the straightened state, the second concave-convex structure and the first concave-convex structure 37 are displaced, and at this time, the first concave-convex structure 37 is in a climbing state. The first concave-convex structure 37 is matched with the milling surface of the mandrel 39, and the first concave-convex structure 37 can axially slide on the mandrel 39, so that the first concave-convex structure 37 has a downward slope tendency under the elastic force of the elastic piece 36, and a rotation reverse torque force is formed. And this reverse torsion can with the gravity of display screen 10 mutual equilibrium, offset this gravity even to when making user operation display screen 10 bend and go up and down, can save strength, do not have the unsmooth sense of card, bend and feel and the operation experience obtains great promotion.
It will be appreciated that the second relief structure and the first relief structure 37 constitute a relief wheel structure having a "climbing" state, which can form a rotational counter-torque. Therefore, the first concave-convex structure 37 and the second concave-convex structure can be exchanged, and the concave-convex wheel structure can be similarly formed, so that the concave-convex wheel structure also has a 'climbing' state, and the rotation reverse torque force can be similarly formed. That is, the first concave-convex structure 37 may be a concave wheel or a cam, and the second concave-convex structure may be a cam engaged with the concave wheel or a concave wheel engaged with the cam, so as to constitute a concave-convex wheel structure in cooperation.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
