Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
The folding screen bending mechanism comprises a lower panel 1, wherein two arc plates 2 are symmetrically fixed on the outer surface of one side of the lower panel 1 along two side edges close to the top, as shown in the partial structure of fig. 1, the partial structure of fig. 2 and the partial structure of fig. 3. An arc-shaped groove 3 is formed in the arc-shaped plate 2, and a matched arc-shaped cover 4 is connected to the outer side of the arc-shaped plate 2 in a sliding manner. The inner side wall of the arc cover 4 is provided with a guide rod 5 inserted into the arc groove 3 at a position corresponding to the arc groove 3. An upper panel 7 is fixedly arranged on the outer surface of the arc-shaped cover 4. The folding screen is now fixed to the lower panel 1 and the upper panel 7.
The two arc plates 2 are arranged on opposite sides along the arc edges, and the arc support plates 201 are matched with the inner cambered surfaces of the arc covers 4.
At this time, the folding screen is mounted on the bottom surface of the upper panel 7 and the surface of the lower panel 1. When the folding screen is required to be lifted from a folded state to an open state: the lower panel 1 is held by hand, then the upper panel 7 is moved, the upper panel 7 drives the arc cover 4 to move, the arc cover 4 drives the sliding table 401 to rotate, the sliding table 401 drives the guide rod 5 to move, the guide rod 5 slides along the inner wall of the arc groove 3, and the arc groove 3 and the inner wall of the arc plate 2 form a sliding rail, namely the moving direction of the guide rod 5. The guide rod 5 drives the arc cover 4 to slide along the inner wall of the arc groove 3, so as to achieve the purpose of rotating the upper panel 7. At this time, the folding screen is opened by the relative rotation of the bottom surface of the upper panel 7 and the lower panel 1. During the period, the arc-shaped supporting plate 201 plays a role in supporting and limiting the arc-shaped cover 4 to rotate, and the bending part of the folding screen can relax or tighten in the accommodating cavity formed by the arc-shaped plate 2, the arc-shaped supporting plate 201 and the arc-shaped cover 4. On the contrary, the upper panel 7 and the lower panel 1 can move in opposite directions, so that the folding screen is turned into a folding state from an opening state, at the moment, the folding and bending parts of the folding screen are bent in an arc shape in the storage cavity formed by the arc-shaped plate 2, the arc-shaped supporting plate 201 and the arc-shaped cover 4, and the problems of crease and screen damage possibly caused by the small-angle turning of the bending part of the folding screen are avoided. Meanwhile, the rotation process of the folding screen bending mechanism is carried out along the arc-shaped groove 3 with a large radian, so that the rotation angle is larger than that of the traditional hinge joint, and the bending part can relax or tighten in a storage cavity formed by the arc-shaped plate 2, the arc-shaped supporting plate 201 and the arc-shaped cover 4 in the rotation process, so that the screen is not easily damaged in the bending process, the bending change is smoother, and the folding screen bending mechanism is smoother and smoother to use.

The inner wall of the connecting plate 901 is in sliding connection with the outer side wall of the lower panel 1. The connecting plate 901 extends to the other side of the lower panel 1 and is connected with a sliding rod 10, and the sliding rod 10 is in sliding connection with the plate surface of the lower panel 1. The linkage plate 8 is rotatably connected with the connecting plate 901.
At this time, the folding screen is mounted on the bottom surface of the upper panel 7 and the surface of the slide plate 9. When the folding screen is required to be lifted from a folded state to an open state: the lower panel 1 is held by hand, then the upper panel 7 is moved, the upper panel 7 drives the arc cover 4 to move, the arc cover 4 drives the sliding table 401 to rotate, the sliding table 401 drives the guide rod 5 to move, the guide rod 5 slides along the inner wall of the arc groove 3, and the arc groove 3 and the inner wall of the arc plate 2 form a sliding rail, namely the moving direction of the guide rod 5. The guide rod 5 drives the arc cover 4 to slide along the inner wall of the arc groove 3, so as to achieve the purpose of rotating the upper panel 7. The sliding table 401 drives the linkage plate 8 to move when rotating, the linkage plate 8 can drive the connecting plate 901 to move downwards under the action of tensile force, the connecting plate 901 drives the sliding plate 9 to move, the sliding plate 9 can indirectly drive the sliding rod 10 to move along the left side of the lower panel 1, then the effect of stably moving the sliding plate 9 downwards is achieved, and when the left side of the arc-shaped cover 4 is attached to the outer surface of the left side of the lower panel 1, the unfolding action is completed, so that the folding screen is completely unfolded.
At this time, by the sliding table 401 and the connecting plate 901, when the folding screen is in the completely opened state and the folded state, the linkage plate 8 forms an inclination angle pointing from the connecting plate 901 to the sliding table 401, thereby providing a supporting force acting opposite to the direction in which the upper panel 7 is to be moved, and realizing a certain positioning and locking function.
In addition, by the relative sliding between the sliding plate 9 and the lower panel 1, a certain damping effect can be provided for the relative sliding of the upper panel 7 and the sliding plate 9 by sliding friction force, and a certain positioning supporting force effect can be provided for the relative movement of the upper panel 7 and the sliding plate 9 by static friction force.
