Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0031] Reference Figures 1 to 5 As shown, the utility model provides a sliding and flipping screen movement device, including a base plate 1, two sliding components 2 arranged on the base plate 1, a flip screen 3 rotatably connected to the sliding components 2, at least one supporting link component 4 arranged between the flip screen 3 and the base plate 1, and two sliding drive components 5; the two sliding components 2 are arranged in parallel on both sides of the base plate 1, and each sliding drive component 5 is driven and connected to a sliding component 2; the sliding drive component 5 is used to drive the sliding component 2 to drive the flip screen 3 to slide, so that the flip screen 3 flips when sliding.

[0032] Specifically, the sliding drive assembly 5 provides the reciprocating motion power for the sliding assembly 2, and the flip screen 3 is rotationally connected to the sliding assembly 2. When the sliding drive assembly 5 drives the sliding assembly 2, the flip screen 3, driven by the sliding assembly 2, follows a reciprocating sliding motion trajectory. When the sliding assembly 2 drives the flip screen 3 in reciprocating sliding motion, it also causes the flip screen 4 to flip, changing its tilt angle. This allows the flip screen 4 to be adjusted to different display angles to meet the varying needs of users.

[0033] The sliding drive assembly 5 includes a driving motor 51 connected to one end of the sliding assembly 2, and an encoder 52 for detecting rotation information of the driving motor 51. Specifically, the driving motor 51 is a stepping motor.

[0034] The sliding assembly 2 includes a screw 21, a screw bracket 22 provided at each end of the screw 21, at least one guide rod 23 arranged along the length of the screw 21, a slider 24 threadedly connected to the screw 21 and movably connected to the guide rod 23, and a connector 25 connected between the flip screen 3 and the slider 24. By providing the screw bracket 22, the ends of the guide rod 23 are also mounted through the screw bracket 22. The screw bracket 22 is also used to limit the sliding travel of the slider 24, preventing the slider 24 from separating from the screw 21 and the guide rod 23 during the sliding process. When the flip screen 3 is flipped, the slider 24 moves back and forth between the two screw brackets 22, and the flip screen 3 also slides back and forth accordingly.

[0035] Furthermore, the sliding assembly 2 further includes a supporting aluminum profile disposed below the screw rod 21 , and two screw rod brackets 22 are mounted on both ends of the supporting aluminum profile.

[0036] The drive motor 51 is drivingly connected to one end of the screw rod 21, and the slider 24 is guided by the guide rod 23. In this embodiment, two guide rods 23 are provided, one located above the screw rod 21 and the other located below the screw rod 21. The middle portion of the slider 24 is a nut that engages with the screw rod 21. The slider 24 has a movable hole defined at both the top and bottom portions, through which the guide rods 23 are arranged.

[0037] The support link assembly 4 includes a support link 41 and a rotating shaft assembly 42 at each end of the support link 41. The first end of the support link 41 is mounted to the back of the flip screen 3 via one rotating shaft assembly 42, and the second end of the support link 41 is mounted to the base plate 1 via another rotating shaft assembly 42. In one embodiment, the rotating shaft assembly 42 includes a rotating shaft connected to the end of the support link 41 and a rotating shaft seat mounted on the base plate 1 or the back of the flip screen 3. When the sliding drive assembly 5 drives the flip screen 3 to slide back and forth, the support link 41 rotates with the rotating shaft assembly 42, thereby driving the flip screen 3 to flip.

[0038] Powered by a drive motor 51, the screw 21 rotates. Through a helical transmission, the screw 21 drives the slider 24 in linear motion, guided by the guide rod 23. Driven by the slider 24, the supporting link 41 performs a combined sliding and swinging motion, driving the flip screen 3 to slide and flip, switching between an open and closed state. An encoder 52 detects the operating angle of the drive motor 51, precisely controlling the distance the slider 24 advances and, therefore, the opening angle of the flip screen 3.

[0039] During the flipping movement of the flip screen 3 , the direction of the transmission chain is: driving motor 51 — screw rod 21 — supporting connecting rod 41 , thereby pushing the flip screen 3 to slide forward and backward.

[0040] In addition, the back of the flip screen 3 is provided with a support seat 6 corresponding to each supporting link assembly 4; the support seat 6 is provided with a receiving groove; please continue to refer to Figure 4 When the flip screen 3 is flipped to the open state, the first end of the supporting link 41 is embedded in the receiving groove of the supporting seat 6, making the entire device more beautiful and further supporting the flip screen 3.

[0041] In another specific embodiment, two support link assemblies 4 and two support bases 6 are provided; the connector 25 of each sliding assembly 2 is fixedly connected to a support base 6. Specifically, one end of the connector 25 is rotatably connected to the slider 24, and the other end of the connector 25 is fixedly connected to the support base 6. The two support link assemblies 4 are arranged parallel to either side of the back of the flip screen 3, and the two support bases 6 are installed parallel to either side of the back of the flip screen 3. This not only provides better support for the flip screen 3 and facilitates flipping of the flip screen 3, but also further ensures that the flip screen 3 completes the sliding and flipping process more synchronously and accurately.

[0042] The sliding and flipping screen motion device provided by the utility model has the following beneficial effects:

[0043] 1) Fewer parts and fewer processing locations can reduce incoming material quality issues;

[0044] 2) Fewer parts, modular assembly, fewer manufacturing processes and types, and fewer manufacturing process problems;

[0045] 3) The structure is relatively simple and modular, making the prevention and resolution of quality issues relatively feasible;

[0046] 4) There are fewer matching positions between the parts and the base plate 1, which reduces the finishing of the base plate 1 and reduces the size requirements of the base plate 1;

[0047] 5) No gear transmission, which reduces the tooth gap in the transmission chain and makes the transmission more precise and controllable;

[0048] 6) The sliding drive components 5 drive the corresponding sliding components 2 to drive the flip screen 3, so that the two sides of the flip screen 3 slide back and forth synchronously. The dual driving force has a high holding force, and a high mechanical margin can be reserved in the design, so the operation smoothness and anti-shake performance of the entire device are high.
