For the connecting shaft 202c, it connects the symmetrically arranged flipping components 202 into a whole, that is, only the flipping component 202 on one side needs to be controlled and adjusted to realize the movement of the structures at both ends together (that is, only one power needs to be provided). The folding rod 202a includes two hinged sheet-like rod bodies, which are divided into a first folding rod 202a-1 and a second folding rod 202a-2. The first folding rod 201a-1 is connected to the first rotating shaft 202d at one end. Furthermore, the first rotating shaft 202d passes through the rotating hole 101a opened on the fixed plate 101 and extends into the accommodating box 102 to be connected to the adjusting component 301.

The upper two ends of the translation rack 301b-1 are respectively connected with the first translation gear 301b-11 and the second translation gear 301b-12. The second translation gear 301b-12 is meshed with the first rotating gear 301a-21. The support block 301b-2 is fixedly connected to the accommodating box 102. The side surfaces of the translation rack 301b-1 are respectively fixed with the second sliding blocks 301b-13. A supporting groove 301b-21 is opened on the inner side of the support block 301b-2. The second sliding block 301b-13 is embedded in the supporting groove 301b-21.

[0043] Furthermore, for the rotation of the flip assembly 202, a driving force needs to be provided and controlled, such as Figure 8The adjusting member 301 shown in the figure includes a rotating member 301a and a translation member 301b. The rotating member 301a drives the flip assembly 202 to move. The rotating member 301a and the translation member 301b are connected. Specifically, the rotating member 301a includes a first rotating member 301a-1 and a second rotating member 301a-2. The first rotating member 301a is a local gear, in which the gears are distributed at 180 degrees. The first rotating member 301a-1 is fixed on the first rotating shaft 202d to form an integrated structure. When the first rotating member 301a-1 rotates, it will drive the first rotating shaft 202d to rotate, and then drive the folding rod 202a to rotate, so that the flip assembly 202 rotates together. The second rotating member 301a-2 is on the same straight line as the center of the first rotating member 301a-1, and includes a first rotating gear 301a-21 and a second rotating gear 301a-22. The rotating gear 301a-21 and the first rotating member 301a-1 are on the same plane, and the first rotating gear 301a-21 is also a local gear. The local gears of the first rotating member 301a-1 and the first rotating gear 301a-21 are arranged on the same side, that is, distributed on the same side. The first rotating gear 301a-21 and the second rotating gear 301a-22 are arranged in parallel and connected into a whole through the second rotating shaft 301a-23, that is, driven by the second rotating shaft 301a-23, the first rotating gear 301a-21 and the second rotating gear 301a-22 move in the same direction together, and the translation member 301b is mainly used to adjust the first rotating member 301a-1 and the second rotating member 301a-2 to rotate respectively, that is, the translation member 301b will mesh with the first connecting member 301a-1 and the second rotating member 301a-2 in turn when moving in one direction, such as Fig.10As shown in the figure, when the first rotating member 301a-1 moves to the right side, the first rotating member 301a-1 rotates counterclockwise, and the flip assembly 202 flips clockwise to flip the display screen from the horizontal position to the vertical position. When the translation member 301b continues to move to the right, the first rotating member 301a-1 will not rotate counterclockwise because it is a local gear. At this time, the second rotating member 301a-2 rotates counterclockwise. Specifically, in order to realize that the translation member 301b drives the first rotating member 301a-1 and the second rotating member 301a-2 to rotate, the translation member 301b is arranged below the first rotating member 301a-1, and includes a translation rack 301b-1 and a support block 301b. 1b-2, the translation rack 301-1 is a rectangular rack, and the first translation gear 301b-11 and the second translation gear 301b-12 are respectively arranged above the translation rack 301b-1, wherein the first translation gear 301b-11 is meshed and connected with the first rotating member 301a-1, and the leftmost gear size of the first translation gear 301b-11 is slightly larger than the other gears, so that when returning (that is, when the translation rack 301b moves to the left), the translation rack 301b can "hook" the gear of the first rotating member 301a-1 to complete the "excitation". After the first rotating member 301a-1 rotates 180 degrees, the translation rack 301b has been turned to After the right translation distance d, the second translation gear 301b-12 meshes with the first rotating gear 301a-21. When the translation rack 301b continues to move to the right, it will drive the first rotating gear 301a-21 to rotate. At this time, since the first rotating member 301a-1 is a local gear, the first rotating member 301a-1 cannot mesh with the translation rack 301b and therefore cannot rotate. Driven by the translation rack 301b, the first rotating gear 301a-21 rotates, thereby driving the second rotating gear 301a-22 to move counterclockwise. Furthermore, in order to keep the translation rack 301b in a stable position, that is, along a predetermined trajectory. The support block 301b-2 is used to support the translation rack 301b-1. The support block 301b-2 shown in the figure is a concave structure. The support block 301b-2 is fixedly arranged on the inner wall of the accommodating box 102. The translation rack 301b-1 passes through the groove in the middle of the support block 301b-2. Second sliding blocks 301b-13 are respectively arranged on the side walls of the translation rack 301b-1. Correspondingly, a supporting groove 301b-21 is opened on the inner side of the support block 301b-2. The second sliding block 301b-13 is embedded in the supporting groove 301b-21, so that the translation rack 301b-1 can move horizontally.

[0044] The limiting assembly 302 includes a limiting rod 302a and a support plate 302b vertically connected to the accommodating box 102, the limiting rod 302a is vertically arranged above the support plate 302b, the limiting rod 302a is connected to the support plate 302b through a second spring 302c arranged at the lower end, a limiting gear 302a-1 meshing with the second rotating gear 301a-22 is arranged on one side of the limiting rod 302a, and a limiting plate 302d is arranged on the other side of the limiting rod 302a, the limiting plate 302d is vertically arranged on the support plate 302b, a limiting groove 302d-1 is provided on the limiting plate 302d in the vertical direction, and the limiting block 302a-2 on the limiting rod 302a is embedded in the limiting groove 302d-1. The accommodating box 102 and the slide rail 201a are respectively provided with a second limiting groove 102b and a third limiting groove 201a-4 at the limiting rod 302a, and the second limiting groove 102b and the third limiting groove 201a-4 are of the same size.

[0045] The limit assembly 302 is used to control the movement of the slide rail 201a. The movement of the limit assembly 302 is controlled by the second rotating gear 301a-22, and further, is controlled and adjusted by the translation rack 301b-1. Fig. 9The limiting assembly 302 shown includes a limiting rod 302a and a support plate 302b, the support plate 302b is vertically arranged with respect to the containing box 102, the limiting rod 302a is vertically arranged above the support plate 302b, the bottom of the limiting rod 302a is connected with a second spring 302c, that is, the two ends of the second spring 302c are respectively connected with the limiting rod 302a and the upper part of the support plate 302b, and one side of the limiting rod 302a is provided with a limiting gear 302a-1 meshing with the second rotating gear 301a-22. When the second rotating gear 301a-22 rotates counterclockwise, the limit rod 302 moves downward under the drive of the limit gear 302a-1. At this time, the second spring 302c is squeezed and has an upward elastic force. In order to make the limit rod 302a move in the vertical direction without deviation, a limit plate 302d is set on the other side of the limit rod 302 (away from the end of the limit gear 302a-1). The limit plate 302d is vertically arranged, that is, vertically arranged above the support plate 302b. 02d is provided with a limiting groove 302d-1 in the vertical direction, and correspondingly, a limiting block 302a-2 is provided on the limiting rod 302a, and the limiting block 302a-2 is embedded in the limiting groove 302d-1, so that the limiting rod 302a can only move in the vertical direction. Furthermore, the second limiting groove 102b and the third limiting groove 201a-4 are respectively provided on the limiting rod 302a of the accommodating box 102 and the slide rail 201a. When locked, the limiting rod 302a passes through the second limiting groove 102 b and the third limiting groove 201a-4 lock the slide rail 201a. After the limiting rod 302a moves downward, the limiting rod 302a disengages from the second limiting groove 102b and the third limiting groove 201a-4, that is, there is no constraint on the slide rail 201a. At this time, the slide rail 201a slides outward under the action of the first spring 201b. The second limiting groove 102b and the third limiting groove 201a-4 are of the same size, which facilitates the limiting rod 302a to enter and exit the second limiting groove 102b and the third limiting groove 201a-4.

[0046] A third translation gear 301b-12 is provided at the lower end of the translation rack 301b-1, and a third rotating gear 301a-3 is provided at the lower part of the translation member 301b. The third rotating gear 301a-3 passes through the rotating hole 102c on the accommodating box 102 and extends to the outside to form a rotating knob 301a-31.

[0047] In summary, the flipping movement of the flipping assembly 202 and the control of the slide rail limit are both performed by linear motion of the translation member 301b. In order to facilitate the control of the translation member 301b, a third translation rack 301b-12 is provided at the lower end of the translation rack 301b-1, and a third rotating gear 301a-3 is provided at the lower part of the translation member 301b. The third translation rack 301b-12 is meshed with the third rotating gear 301a-3, and the third rotating gear 301a-3 passes through the rotating hole 102c on the accommodating box 102 and extends to the outside to form a rotating gear. The translation rack 301b-1 can be controlled by rotating the knob 301a-31, that is, the translation rack 301b-1 and the first rotating member 301a-1 are adjusted to rotate, thereby driving the flip assembly 202 to drive the display screen to flip, and then continue to turn the rotating knob 301a-31 to adjust the translation rack 301b-1 and the second rotating member 301a-2 to rotate so that the limit rod 302a releases the restriction on the slide rail 201a, and the slide rail 201a drives the display screen to move in a straight line. The operation is convenient and quick.
