The second link 44 has one end connected to the protruding portion of the cam and the other end connected to the second bracket 30.

Specifically, the motor 41 can drive the rotating member 42 to rotate around the axis of the motor 41, and when the rotating member 42 rotates in the first direction or the second direction, the rotating member 42 drives the first bracket 20 and the second bracket 30 to move synchronously through the first connecting rod 43 and the second connecting rod 44, so that the first bracket 20 and the second bracket 30 move close to or away from each other. By setting the rotating part 42 as a cam and driving the cam to rotate in a motor-driven manner, not only the assembly structure is simple, but also the driving manner is convenient and efficient, and it is further ensured that the first support 20 and the second support 30 can move towards each other or away from each other.

According to an embodiment of the present application, the screen supporting assembly 100 further includes a motor 41, the motor 41 is disposed on the central bracket 10, and the motor 41 drives the rotating member 42 to rotate around an axis of the motor 41.

That is, as shown in fig. 3, the rotating member 42 has a central symmetrical structure, and may be a sheet-shaped shuttle. The spindle-shaped rotor 42 has a major axis and a minor axis, and a longer direction is a major axis direction and a shorter direction is a minor axis direction. One end of the rotating member 42 in the long diameter direction may be movably connected to a first end of the first link 43, and the other end of the rotating member 42 in the long diameter direction may be movably connected to a first end of the second link 44. When the motor 41 drives the rotating member 42 to rotate, the first link 43 and the second link 44 can move together with the rotating member 42 to move the first bracket 20 and the second bracket 30 synchronously. By arranging the rotation member 42 with central symmetry, not only can the first support 20 and the second support 30 be driven synchronously, but also the structures can be more compact, and the whole space utilization rate is improved.

Of course, the connecting shaft may be an integral part of the first connecting rod 43 or the second connecting rod 44, and the end of the first connecting rod 43 or the second connecting rod 44 having the connecting shaft is inserted into the mounting hole 421, so as to be pivotally connected to the rotating member 42. When the motor 41 drives the rotation member 42 to rotate, the first link 43 and the second link 44 may move together with the rotation member 42 to move the first bracket 20 and the second bracket 30 in synchronization, thereby enabling the screen size to be changed.

It should be noted that the screen supporting assembly 100 of the present application is not limited to a transmission manner using symmetrical connecting rods, and any manner of achieving bidirectional extension and retraction of the screen through a symmetrical transmission structure is within the application scope of the present application.

According to one embodiment of the present application, the ratio of the long diameter to the short diameter of the rotary member 42 is greater than 1.5.

That is, since the first end of the first link 43 is connected to the first bracket 20, the second end of the first link 43 is connected to the rotation member 42, the first end of the second link 44 is connected to the second bracket 30, and the second end of the second link 44 is connected to the rotation member 42, when the rotation member 42 is rotated by the motor 41, the distance between the second end of the first link 43 and the second end of the second link 44 is maintained to be approximately the length of the major diameter. The distance between the first end of the first link 43 and the first end of the second link 44 gradually increases or decreases.

When the first and second brackets 20 and 30 are located at the storage positions, the distance between the first end of the first link 43 and the first end of the second link 44 is minimized to be approximately equal to the length of the short diameter, and when the distance between the first end of the first link 43 and the first end of the second link 44 is gradually increased, the distance between the first and second brackets 20 and 30 is gradually increased, and the size of the screen is gradually increased.

It should be noted that the screen expansion rate in the prior art is 10%, and the screen expansion rate in the present application can reach 13%. The ratio of the long diameter to the short diameter of the rotating member 42 can be selected according to the specific extension range of the screen, and the expansion ratio of the screen can be further increased by increasing the ratio of the long diameter to the short diameter of the rotating member 42.

In some embodiments of the present invention, the motor 41 is an in-wheel motor 41, and the motor 41 is disposed at a central position of the central bracket 10.

That is, the motor 41 may be an in-wheel motor 41, that is, the coil of the motor 41 may be integrated on the wheel hub to form a thin-plate type motor 41 structure with small thickness, and the main shaft of the motor 41 is fixedly connected with the wheel hub by means of a key. Compared with a common motor, a large number of mechanical structures are omitted in the hub motor 41, and all parts of the motor 41 are integrated together, so that the overall size is reduced, space stacking among all the structures is facilitated, and the light and thin design of electronic equipment is facilitated. The motor 41 is disposed at the center of the central frame 10 to facilitate the control of the rotating member, so that not only the overall structure of the screen supporting assembly 100 is more compact, but also the first frame 20 and the second frame 30 can move synchronously.

According to an embodiment of the present application, the first end edge and the second end edge of the center bracket 10 are respectively provided with an escape groove 11 recessed toward the center of the center bracket 10, and the connection portion of the first link 43 and the first bracket 20 and the connection portion of the second link 44 and the second bracket 30 are located in the escape groove 11 in a state where the first bracket 20 and the second bracket 30 are located at the storage position.

That is, as shown in fig. 1, an escape groove 11 is provided at each of first and second ends of the center bracket 10, and the escape groove 11 is located at an edge of the center bracket 10 and is recessed toward the center of the center bracket 10. When the first and second brackets 20 and 30 are located at the storage positions, the portion of the first link 43 connected to the first bracket 20, and the portion of the second link 44 connected to the second bracket 30 can be located in the escape groove 11. The avoidance groove 11 is formed in the edge of the central support 10, so that the whole structure is more compact, the minimum size of the screen is further reduced, and the adjustable range of the screen is enlarged.

In some embodiments of the present invention, the first bracket 20 and the second bracket 30 are symmetrically disposed with respect to one axis of symmetry of the central bracket 10.

That is, as shown in fig. 1 and 2, since the screen support assembly 100 of the present application expands and contracts the screen by bi-directional expansion, the uniformity of bi-directional expansion is ensured by symmetrically arranging the first and second brackets 20 and 30 with respect to one axis of symmetry of the central bracket 10, and the stacking of the entire space is facilitated, thereby improving the space utilization. Compared with a one-way telescopic structure, under the same stroke, the expansion performance of the whole machine can be doubled.

According to one embodiment of the present application, the rotating member 42 drives the first bracket 20 and the second bracket 30 to move synchronously, and the moving directions of the first bracket 20 and the second bracket 30 are opposite.

That is, as shown in fig. 1 and 2, the rotating member 42 can drive the first bracket 20 and the second bracket 30 to synchronously move in opposite directions, so that the first bracket 20 and the second bracket 30 can simultaneously extend to both ends of the central bracket 10, or simultaneously retract to the center of the central bracket 10, thereby achieving bidirectional extension and retraction of the screen.

When the first stand 20 and the second stand 30 move from the positions shown in fig. 1 to the positions shown in fig. 2, that is, the first stand 20 and the second stand 30 move away from each other, the distance between the first stand 20 and the second stand 30 gradually increases, the first stand 20 and the second stand 30 may move from the storage position to the extended position, or may move from any position to the extended position, and the size of the screen gradually increases. Through rotating the rotation piece 42, the rotation piece 42 drives the first connecting rod 43 and the second connecting rod 44 to move, and the first connecting rod 43 and the second connecting rod 44 can drive the first support 20 and the second support 30 to move away from or towards each other at the same time, so that the size of the screen can be effectively adjusted, and the expansion effect of the screen is enhanced.

The operation of the first and second supports 20 and 30 will be described by taking the example that they are movable in the left and right directions.

As shown in fig. 1 and 2, the first bracket 20 is a left extension bracket provided at a left side of the center bracket 10, the left extension bracket being a support structure when the screen is extended leftward, the second bracket 30 is a right extension bracket provided at a right side of the center bracket 10, and the right extension bracket being a support structure when the screen is extended rightward. When the first and second brackets 20, 30 are moved from the stowed position shown in fig. 1 to the deployed position shown in fig. 2, the first bracket 20 extends to the left and the second bracket 30 extends to the right. When the first and second brackets 20, 30 are moved from the deployed position shown in fig. 2 to the stowed position shown in fig. 1, the first bracket 20 is retracted to the right and the second bracket 30 is retracted to the left.

In addition, laser position detectors and speed sensors may be installed on the left and right sides of the central support 10 to detect the moving state of the first support 20 and the second support 30 relative to the central support 10 during the extending process. By adopting a speed and position double-closed-loop control mode, the accurate and real-time stepless adjustment of the first support 20 and the second support 30 at any extending position is realized, so that the first support 20 and the second support 30 can stop at the specified position.

In summary, according to the screen support assembly 100 of the embodiment of the present invention, not only is the expansion rate of the screen size effectively increased, so that the screen can be suitable for different scenes, and the user experience is improved, but also the setting is simple and the realizability is strong.
