[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figures 1 to 7 , an embodiment provided by the present invention:

[0030] A foldable combined display screen includes a base plate 3, a first frame 7 and a second frame 8. An adjusting mechanism 13 is arranged inside the base plate 3. The center of the upper end face of the outer wall of the base plate 3 is fixedly provided with an outer shell 1. Slide rails 5 are fixedly provided on both sides of the inner wall of the outer shell 1 near the rear end. Threaded rods 6 are rotatably arranged on both sides of the center of the upper end face of the base plate 3 near the two sides. Three screen bodies 9 are embedded in the rear end faces of the first frame 7 and the second frame 8. Slide blocks 12 are fixedly provided at the centers of both sides of the first frame 7;

[0031] Thread grooves 10 are penetrated and opened on both sides of the front ends of both the upper and lower end faces of the first frame 7. A hinge mechanism 4 is arranged on the side of the front end faces of the first frame 7 and the second frame 8 that are close to each other. A rotating mechanism 11 is arranged inside the two first connecting pieces 402.

[0032] Specifically, through the outer shell 1, the adjusting mechanism 13 can be used to lift the first frame 7, which is convenient for storing the first frame 7 and the second frame 8, so as to achieve the effect of protecting the screen body 9. Through the slide rail 5 and the slide block 12, the first frame 7 can be horizontally fixed to prevent it from shaking during the lifting process and damaging the threaded rod 6. Through the cooperation of the hinge mechanism 4 and the rotating mechanism 11, the first frame 7 and the second frame 8 can be folded to reduce their floor area and achieve the effect of being convenient for placement and handling.

[0033] Refer to Figure 1 ,Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , two No. 2 connecting pieces 403 are respectively fixedly arranged at the upper and lower ends near the center of one side of the front end face of the first frame 7, two No. 1 connecting pieces 402 are respectively fixedly arranged at both ends of one side of the front end face of the second frame 8, and the upper and lower end faces of the double-shaft servo motor 401 are respectively fixedly connected with the two No. 2 connecting pieces 403;

[0034] The bearing 1101 is fixedly sleeved on the upper end of the outer wall of the inserted shaft 1104, the threaded cover 1102 is fixedly sleeved on the outer wall of the bearing 1101, the four clamping blocks 1103 are all fixedly arranged at the upper end near the center of the outer wall of the inserted shaft 1104, and the cross groove 1105 is opened at the center of the lower end face of the inserted shaft 1104.

[0035] Specifically, start the double-shaft servo motor 401 to drive the cross inserts 16 at its two output ends to rotate, and drive the two inserted shafts 1104 to rotate through the design of the cross inserts 16 being inserted into the cross groove 1105, and drive the two No. 1 connecting pieces 402 to rotate while the inserted shafts 1104 rotate through the design of the clamping blocks 1103 on the outer walls of the two inserted shafts 1104 being inserted into the card slots 15, so as to be able to achieve the effect of changing the hinge angle between the first frame 7 and the second frame 8, and thus be able to realize the folding of the first frame 7 and the second frame 8 to reduce its floor area and facilitate its placement and handling.

[0036] Refer to Figure 1 , Figure 4 , the rotating shaft 1301 is rotatably arranged at the centers of both sides of the inner wall of the bottom plate 3, the two longitudinal bevel gears 1302 are respectively fixedly sleeved on both sides of the outer wall of the rotating shaft 1301, and the two transverse bevel gears 1303 are respectively fixedly arranged at the lower end faces of the two threaded rods 6 and are respectively meshed with the two longitudinal bevel gears 1302.

[0037] Specifically, the rotating shaft 1301 can drive the two longitudinal bevel gears 1302 to rotate, so as to drive the two transverse bevel gears 1303 meshed with them to rotate synchronously through the two longitudinal bevel gears 1302, so as to achieve the effect of synchronously rotating the two threaded rods 6.

[0038] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the two threaded rods 6 respectively threadedly penetrate through the two threaded grooves 10 at the lower and upper ends among the four threaded grooves 10, and the two sliders 12 are respectively slidably arranged inside the two slide rails 5.

[0039] Specifically, the design of the threaded rod 6 passing through the threaded groove 10 enables the rotation of the threaded rod 6 to drive the first frame 7 to move along the direction of the threaded rod 6, and the sliding rail 5 and the slider 12 are used to achieve the stable effect of the first frame 7 horizontally, preventing it from shaking during the movement and damaging the threaded rod 6.

[0040] Refer to Figure 5 、 Figure 6 At the front end of the upper end faces of the two first connecting pieces 402, threaded rings 14 are fixedly arranged. Four clamping grooves 15 are formed in the inner walls of the two first connecting pieces 402. Two threaded covers 1102 are respectively sleeved on the outer walls of the two threaded rings 14 in a threaded manner, and eight clamping blocks 1103 are respectively slidably embedded in the eight clamping grooves 15.

[0041] Specifically, the threaded cover 1102 and the threaded ring 14 can be used to fix the position of the embedded shaft 1104, which is convenient for cooperating with the bearing 1101 to fix one end of the embedded shaft 1104 away from the dual-axis servo motor 401 while the embedded shaft 1104 is rotating, preventing it from shaking and affecting the rotation effect.

[0042] Refer to Figure 4 、 Figure 7 At the center of one side of the outer wall of the bottom plate 3, a single-axis servo motor 2 is fixedly arranged. One end of the rotating shaft 1301 is fixedly connected to the output end of the single-axis servo motor 2. Two cross-shaped inserts 16 are fixedly arranged at the two output ends of the dual-axis servo motor 401, and the two cross-shaped inserts 16 are respectively embedded in the two cross-shaped grooves 1105.

[0043] Specifically, the single-axis servo motor 2 can drive the rotating shaft 1301 to rotate. While the dual-axis servo motor 401 drives the two cross-shaped inserts 16 to rotate, the two cross-shaped inserts 16 embedded in the two cross-shaped grooves 1105 can drive the two embedded shafts 1104 to rotate.

[0044] Working principle: The folding effect of the first frame 7 and the second frame 8 can be achieved through the cooperation of the hinge mechanism 4 and the rotating mechanism 11, thereby reducing its floor area and facilitating its placement and handling. At the same time, the single-axis servo motor 2 can drive the adjusting mechanism 13 to synchronously rotate the two threaded rods 6. By rotating the two threaded rods 6, the height of the first frame 7 can be adjusted, so that the folded first frame 7 and the second frame 8 can be stored in the housing 1. The housing 1 protects the screen body 9 on the first frame 7 and the second frame 8, preventing it from being damaged due to bumps during handling. At the same time, it is convenient to quickly separate it from the housing 1 through the adjusting mechanism 13, avoiding the problem that the protective measures for the screen body 9 in the prior art are relatively troublesome to disassemble.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
