[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1

[0034] like Figure 1-Figure 10 As shown, this embodiment discloses a display screen support capable of freely converting a curved or straight surface, comprising a base 1, a support arm 2, a joint transmission mechanism 3 and a first curved or straight support conversion structure 4, wherein one end of the support arm 2 is connected to the base 1, the base 1 is placed on the ground to provide a supporting force, the support arm 2 is used to adjust the height of the screen from the ground, the joint transmission mechanism 3 is arranged on the other end of the support arm 2, the first curved or straight support conversion structure 4 is arranged on the joint transmission mechanism 3, the first curved or straight support conversion structure 4 comprises a plurality of support members 41, a plurality of flip assemblies 42 and a connecting rod assembly 43, the flip assemblies 42 are arranged on the support members 41 one by one, and the plurality of flip assemblies 42 are connected in a head-to-tail rotation manner, A plurality of support members 41 form a support surface for directly mounting a screen. The connecting rod assembly 43 drives the flip assembly 42 to rotate. The flip assembly 42 includes a fixed block 421, a telescopic rod 422 and a pivot 423. The fixed block 421 is arranged on the support member 41. Two adjacent fixed blocks 421 are hinged by the pivot 423. Both ends of the telescopic rod 422 are rotatably connected to two adjacent fixed blocks 421 respectively. The telescopic rod 422 has its own damping to form a triangular support with high support stability. The flip assembly 42 is used to realize the conversion of the support surface between a curved surface and a straight surface, and the curvature of the support surface is adjustable, so as to support straight surfaces and screens with different curvatures.

[0035] Furthermore, the flip assembly 42 also includes a first elastic element 424, which is sleeved on the pivot 423. Both ends of the first elastic element 424 respectively contact with two adjacent fixed blocks 421. The two adjacent fixed blocks 421 are staggered with each other and are arranged at the staggered parts on the pivot 423, so that multiple fixed blocks 421 can form a supporting force along a straight line direction, thereby improving the bearing capacity and stability of the structure. Only one fixed block 421 needs to be supported to achieve the support of the entire supporting surface to the ground. The first elastic element 424 is a torsion spring, which is used to provide a reset force after the multiple support members 41 are deformed.

[0036] Furthermore, the connecting rod assembly 43 includes multiple connecting rods 432 and push-pull rods 431. The multiple connecting rods 432 are connected end to end in sequence to form a rod group. The push-pull rod 431 is rotatably connected to one end of the rod group, and the other end of the rod group is rotatably connected to the fixed block 421 at the end. The rod group is used to transmit the driving force from the push-pull rod 431. The connection points between the multiple connecting rods 432 are opposite to the rotation points on each fixed block 421. The rod group can follow the multiple support members 41 to perform deformation movements.

[0037] Preferably, a fixing pin 433 is provided on the fixing block 421 at the end position of the supporting surface, and the other end of the rod group is rotatably connected to the fixing block 421 through the fixing pin 433. The rod group can rotate and deform along with the supporting surface, thereby ensuring the stability of the deformation driving force transmission and the stability of the supporting surface after being fixed.

[0038] Furthermore, the joint transmission mechanism 3 includes a base 31, a guide seat 34 and a guide block 35. The guide seat 34 is arranged on the base 31, and the base 31 is connected to the support arm 2. The guide block 35 is slidably connected to the guide seat 34. The guide block 35 follows the telescopic movement of the connecting rod assembly 43 so that the shape of the support surface can be changed, thereby playing a guiding role.

[0039] Furthermore, a groove structure 434 formed by two protrusions is provided at the end of the push-pull rod 431, and the guide seat 34 is arranged in the groove structure 434. The width of the groove structure 434 limits the degree of contraction of the push support member 41, thereby playing a limiting role.

[0040] See Figure 7-10 A sloped portion 341 is provided on one side wall of the guide block 35, and the sloped portion 341 is arranged along the edge of the guide block 35 and is bent around the center. A sloped surface is provided on the inner side wall of the groove structure 434, and the sloped surface and the sloped portion 341 are wedge-matched. When the support surface rotates around the axis, a pulling force is generated to push the connecting rod assembly 43 to pull the multiple support members 41 to deform. The wedge-shaped match converts the rotation around the axis into movement along the length direction of the support surface, making full use of the rotating shaft structure 32 of the display screen bracket itself that can freely convert the curved and straight surfaces, simplifying the overall structural complexity, and making it easy for users to adjust.

[0041] Preferably, the joint transmission mechanism 3 also includes a pressure block 36 and a second elastic element 37. The guide seat 34 is provided with a sliding groove for the guide block 35 to slide. One side of the sliding groove penetrates the side wall of the guide seat 34 to form an opening. The pressure block 36 is slidably connected to the opening. The second elastic element 37 pushes the pressure block 36 to squeeze the guide block 35. The guide block 35 is subjected to an extrusion force when sliding to prevent the support surface from being deformed by external force. A baffle is also provided at the opening, which is used to press the second elastic element 37 to prevent the pressure block 36 and the second elastic element 37 from falling out.

[0042] More preferably, the slide groove is an arc groove centered on the shaft structure 32, and the guide block 35 is also an arc block, so that the guide block 35 and the push-pull rod 431 form a stable contact during the rotation process to ensure the stability of the curve-to-straight conversion.

[0043] More preferably, the joint transmission mechanism 3 also includes a rotating shaft structure 32 and a frame 33. The frame 33 is arranged at both ends of the base 31. The frame 33 is connected to the base 31 through the rotating shaft structure 32, so that the first curved to straight support conversion structure 4 can rotate with the rotating shaft structure 32 to adjust the curvature of the support surface. A torsion spring 38 is provided around the axis on the rotating shaft structure 32. The torsion spring 38 is used to provide damping for the rotating support surface, thereby realizing follow-up adjustment of the support surface and facilitating user operation. The frame 33 is arranged around the guide seat 34 to prevent foreign objects from invading and getting stuck.

[0044] More preferably, a through hole 331 is provided on the frame 33, and the push-pull rod 431 is slidably connected to the through hole 331. The frame 33 is arranged close to the guide seat 34 to stabilize and guide the push-pull rod 431. The end of the frame 33 is fixedly connected to the support member 41 to provide supporting force for the support member 41.

[0045] The working process of the display screen bracket capable of freely converting curved and straight surfaces is as follows:

[0046] When supporting a straight screen, the support member 41 is pushed to rotate around the axis of the rotating shaft structure 32, and the inner wall of the groove structure 434 at the end of the push-pull rod 431 on the connecting rod assembly 43 contacts the inclined portion 341 on the guide seat 34. At the same time, the push-pull rod 431 rotates around the axis, and the guide seat 34 pulls the connecting rod assembly 43 to move, and the connecting rod assembly 43 pulls the outermost support member 41 to tighten, so that the support surface formed by the multiple support members 41 is straightened to form a plane; when supporting a curved screen, the support member 41 is pushed to rotate in the opposite direction around the axis of the rotating shaft structure 32, and the pulling force of the guide seat 34 on the connecting rod assembly 43 disappears. The multiple support members 41 shrink under the action of the first elastic element 424, so that the support surface formed by the multiple support members 41 shrinks inward to form a curved surface with an arc, and the arc size of the support surface can be changed by adjusting the rotation angle.

[0047] Embodiment 2

[0048] The present embodiment also discloses a display screen bracket capable of freely converting a curved or straight surface, comprising a second curved or straight support conversion structure 5, wherein the second curved or straight support conversion structure 5 is arranged in a mirror image with the first curved or straight support conversion structure 4, and the second curved or straight support conversion structure 5 is synchronously driven to deform by the joint transmission mechanism 3, and two combined guide seats 34 and guide blocks 35 are arranged side by side on the base 31 of the joint transmission mechanism 3, wherein the two guide blocks 35 are arranged in a mirror image, and the first curved or straight support conversion structure 4 and the second curved or straight support conversion structure 5 on the left and right sides are respectively pushed to synchronously deform through the two guide blocks 35 and the guide seats 34, thereby driving the multiple support members 41 on both sides to change the angle and change the curvature of the support surface, and the mirror image arrangement of the first curved or straight support conversion structure 4 and the second curved or straight support conversion structure 5 can make the coverage of the support surface larger and make the stability of the supported display screen better.
