As shown in FIGS. 1 and 2 , the present embodiment provides a display screen assembly with a rotatable screen, including a screen 10, a base 2, a fixed base 3, a driving assembly 4, a moving member 5, a force-applying member 6, a pulling member 7 and a supporting assembly 8; the upper side is the first side, the lower side, i.e., the opposite side of the first side is the second side, the fixed base 3 is located on the first side of the base 2 and is fixed on the base 2, the force-applying member 6 is located on the first side of the fixed base 3 and is specifically arranged on the lower left end of the screen 10, and two moving members 5 are arranged on the second side of the screen 10, the moving member 5 and the fixed base 3 and different moving members 5 can move relative to each other by pulling by the pulling member 7, and the pulling member 7 can make each moving member 5 move upward and close to the screen 10 under the drive of the driving assembly 4;

As described above, one of the two moving parts 5 can move to a position closer to the screen 10 than the other one, and the moving part 5 that can move to the upper side is fixedly connected to the force-applying member 6; correspondingly, the supporting assembly 8 is located at the lower right side of the screen 10 and is used to support the screen 10, and a part of it can rotate with the rotation of the screen 10 so as not to hinder the rotation of the screen 10; in this embodiment, the force-applying member 6 can support the screen 10 together with the supporting assembly 8 when the moving part 5 connected thereto is in a stationary state, and can be driven during the up and down movement of the moving part 5 to apply force to the left end of the screen 10, so that the screen 10 can rotate with the supporting assembly 8 as the fulcrum.

Specifically, the moving member 5 of the two moving members 5 that is not connected to the force-applying member 6 is the first moving member 51, and the moving member 5 connected to the force-applying member 6 is the second moving member 52. In this embodiment, the first moving member 51 can first move upward relative to the fixed seat 3. To achieve this setting, as shown in Figures 3 and 4, the fixed seat 3 is provided with a first matching groove 31 extending from bottom to top and penetrating the fixed seat 3, and the first moving member 51 is located in the first matching groove 31 and can move up and down along the first matching groove 31.

More specifically, the first matching groove 31 is in a right-angled U-shape with an opening facing right, and the middle position of the right part of the fixed seat 3 is penetrated from top to bottom. The penetrated part of the fixed seat 3 and the first matching groove 31 form an opening facing right on the fixed seat 3, and two vertical hook-shaped (hereinafter referred to as "X-shaped") first hooking parts 32 are formed on the front and rear sides of the right opening. Correspondingly, the first moving member 51 includes a body 511 and two bending parts 512, wherein the body 511 is in a rectangular parallelepiped shape, the bending part 512 is L-shaped, and the bending part 512 includes two parts extending in the front-to-back direction and in the left-to-right direction, respectively. The two bending parts 512 are respectively located on the front and rear sides of the body 511, and the parts of the two bending parts 512 extending in the front-to-back direction are connected to the left part of the body 511 as a whole, and the parts of the two bending parts 512 extending in the left-to-right direction are spaced apart from the body 511 to form an avoidance space 513.

When the first moving member 51 is matched with the fixed seat 3, the corresponding matching relationship between the parts of the two is: the bending portion 512 is matched with the first hooking portion 32, and the body 511 is matched with the right opening portion on the fixed seat 3. In this embodiment, the design of the first hooking portion 32 can cooperate with the U-shaped design of the first matching groove 31 to ensure the stability of the up and down movement of the first moving member 51.

Furthermore, a first elastic member 9, which is specifically a spring, is further provided on the outside of the two first hooking and folding portions 32, that is, on the front and rear sides of the fixing seat 3. The first elastic member 9 is arranged in the up-down direction, and its lower end is welded to the base 2, and its upper end is welded to a first functional rod 11, and the first functional rod 11 is arranged in the front-to-back direction; corresponding to the first functional rod 11, a first guide groove 33 is provided on the fixing seat 3, and the first guide groove 33 extends in the up-down direction and penetrates from the outer surface of the fixing seat 3 inward to the first hooking and folding portion 32. The middle part of the portion 32 (that is, in the first matching groove 31); the first guide groove 33 is a waist-shaped groove, the upper edge of which is located below the upper edge of the fixed seat 3, and the lower edge of which is located above the lower edge of the fixed seat 3; the first functional rod 11 is inserted into the first guide groove 33 and can move up and down along the first guide groove 33, the rear end of which is exposed to the rear side of the fixed seat 3 and is welded to the first elastic member 9, and the front end of which is located in the first matching groove 31 and penetrates into the lower part of the first movable member 51, and is fixedly connected to the first movable member 51 by interference fit. In this embodiment, when the lower wall of the first movable member 51 contacts the base 2, the first elastic member 9 is in a natural state without elastic deformation. Optionally, the first functional rod 11 and the first movable member 51 can also be fixed in a welding connection or a threaded connection, etc.,

In this way, when the first movable member 51 moves upward along the first matching groove 31 under the action of external force until the first functional rod 11 abuts against the upper edge of the first guide groove 33, the first elastic member 9 will be stretched under the drive of the first functional rod 11; thereafter, if the external force disappears, the first elastic member 9 will drag the first functional rod 11 downward, and finally drive the first movable member 51 to reset.

It should be noted that the position of the first movable member 51 at which the first elastic member 9 is in a natural state can be flexibly adjusted by those skilled in the art as needed. For example, a first stop beam (not shown) can be added to the first matching groove 31 to span the first matching groove and be located at the lower side of the first movable member 51, so that when the first movable member 51 contacts and is blocked by the first stop beam, the first elastic member 9 is in a natural state. Furthermore, by adjusting the position of the first stop beam in the first matching groove 31, the downward travel limit of the first movable member 51 in the first matching groove 31 can be conveniently redefined.

Please continue to refer to FIG. 3 and FIG. 4 . In this embodiment, a second matching groove 514 extending from top to bottom is further provided on the first moving member 51 . The second moving member 52 is located in the second matching groove 514 and can move up and down along the second matching groove 514 .

More specifically, the second moving member 52 has an appearance similar to the fixed seat 3, is also provided with a second hooking and folding portion 521 similar to the first hooking and folding portion 32, and is also provided with an opening feature facing right; the main difference between the second moving member 52 and the fixed seat 3 is that its volume is smaller than the fixed seat 3, and its left wall is also penetrated, having the feature of being connected from left to right. Correspondingly to the second moving member 52, in the present embodiment, a hollow structure is also provided in the middle part of the body 511 along the left and right directions and downwardly through it, and the upper surface of the body 511 is also provided with the aforementioned second matching groove 514 extending from top to bottom, and the second matching groove 514 is the imitation shape of the second moving member 52, and can cooperate with the hollow structure of the body 511, so that the body 511 is connected from left to right and can lead to its upper side from its hollow structure, thereby realizing that the second moving member 52 can be set up along the second matching groove 514 and move up and down.

Furthermore, a second functional rod 12 similar to the first functional rod 11 is also provided on the second movable member 52, and a second elastic member 13 similar to the first elastic member 9 is also provided on the upper side of the fixed seat 3; more specifically, the two second elastic members 13 are arranged straight in the up and down directions, and are respectively located between the main body 511 and the bending portion 512, and are at least partially located in the avoidance space 513; second guide grooves 5111 are provided on the front side wall and the rear side wall of the main body 511, and the second guide grooves 5111 are arranged similarly to the first guide grooves 33, which are waist-shaped and extend from the outer surface of the main body 511 toward the inside of the main body 511, and penetrate into the hollow structure of the main body 511.

According to the above, the second functional rod 12 is arranged in the second guide groove 5111, the front end of which penetrates into the second moving member 52 and is interference fit with the second moving member 52, and the rear end of which penetrates to the rear side of the second guide groove 5111 and is located in the avoidance space 513, and is welded to the upper end of the second elastic member 13; correspondingly, the lower end of the second elastic member 13 is welded to the upper surface of the fixing seat 3. Please refer to Figures 4 and 5. In this embodiment, a second stop beam 515 is provided in the hollow structure of the body 511. The second stop beam 515 is horizontally extended in the body 511 along the front-to-back direction and is connected to the body 511 as a whole, and is used to block the downward trajectory of the second moving member 52 and determine the lowest point of the second moving member 52 downward; preferably, in this embodiment, when the second moving member 52 is blocked by the second stop beam 515 and cannot go downward, the state of the second elastic member 13 is set to the natural state when there is no elastic deformation. Preferably, the height of the first movable member 51 in the vertical direction of this embodiment is greater than the height of the fixing seat 3 in the vertical direction to ensure that a certain distance is maintained between the second functional rod 12 and the fixing seat 3 at all times and leave space for the second elastic member 13 to be arranged.

Based on the above structure, it can be known that the first movable member 51 in this embodiment can move upward along the first matching groove 31 under the action of external force. When the external force disappears, the elastic deformation of the first elastic member 9 can cause the first movable member 51 to move downward along the first matching groove 31 in the opposite direction. Similarly, under the action of external force, the second movable member 52 can move upward along the second matching groove 514. When the external force disappears, the elastic deformation force of the second elastic member 13 can cause the second movable member 52 to move downward along the second matching groove 514 in the opposite direction.

Please further refer to Figures 6 and 7. In this embodiment, the aforementioned drive assembly 4 is provided on the left side of the fixed seat 3, and is also provided with two pulling members 7 which are specifically gear belts and several wheel members which are specifically gears (such as the driving wheel 41, guide wheel and passive wheel 15 described below). The drive assembly 4 can drive the pulling member 7 by means of the wheel members to provide the above-mentioned external force to the first movable member 51 and the second movable member 52; optionally, the drive assembly 4 can be fixed on the fixed seat 3 or on the base 2.

More specifically, the drive assembly 4 includes a drive motor and a drive wheel 41 that can be driven by the drive motor to rotate; in this embodiment, a first guide wheel 14 and a passive wheel 15 are mounted on the fixed seat 3, a second guide wheel 16 and a third guide wheel 17 are mounted on the first movable member 51, and a fourth guide wheel 18 is mounted on the second movable member 52, wherein the first guide wheel 14 is located on the upper right side of the drive wheel 41, the passive wheel 15 is located on the front side of the first guide wheel 14 and has a coaxial transmission relationship with the first guide wheel 14, and the first guide wheel 14 can drive the passive wheel 15 to rotate; the second guide wheel 16 is located on the right side of the first guide wheel 14 and is arranged inside the first movable member 51, specifically mounted on the lower left wall in the middle position of the body 511; the third guide wheel 17 is located on the upper right side of the passive wheel 15 and on the upper side of the second guide wheel 16; the fourth guide wheel 18 is located inside the second movable member 52, specifically mounted on the lower left wall in its middle position.

Correspondingly, the two pulling members 7 in the present embodiment are respectively the first pulling member 71 and the second pulling member 72, one end of the first pulling member 71 is fixed on the driving wheel 41, the first pulling member 71 extends from the end to the first guide wheel 14 and the second guide wheel 16, and cooperates with the first guide wheel 14 and the second guide wheel 16, and is fixedly connected with the first movable member 51 after being guided by the first guide wheel 14 and the second guide wheel 16 in sequence, specifically by welding (see welding point A in Figure 7); one end of the second pulling member 72 is fixed on the passive wheel 15, and the second pulling member 72 extends from the end to the third guide wheel 17 and the fourth guide wheel 18, cooperates with the third guide wheel 17 and the fourth guide wheel 18, and is fixedly connected with the second movable member 52 after being guided by the third guide wheel 17 and the fourth guide wheel 18 in sequence, specifically by welding (see welding point B in Figure 6). Furthermore, when arranging the first pulling member 71 and the second pulling member 72, in order to avoid unnecessary friction between them and the fixed seat 3 and the first movable member 51, in this embodiment, notches for avoiding the first pulling member 71 and the second pulling member 72 are respectively provided on the upper left part of the fixed seat 3 and the first movable member 51.

It should be noted that the fixed connection method between the first pulling member 71 and the first movable member 51, and the fixed connection method between the second pulling member 72 and the second movable member 52 can be flexibly set by those skilled in the art. For example, a structure similar to a pull ring (not shown) can be fixed on the first movable member 51 and the second movable member 52, and then the first pulling member 71 and the second pulling member 72 are provided with a structure that can be fixedly connected to the pull ring, so that the fixed connection between the first pulling member 71 and the first movable member 51 and between the second pulling member 72 and the first movable member 51 can be achieved by providing an adapter such as a pull ring.

It should also be noted that the schemes for setting up the first guide wheel 14, the second guide wheel 16, the third guide wheel 17 and the fourth guide wheel 18 in this embodiment are similar, and the scheme and the scheme for setting up the passive wheel 15 are common knowledge to those skilled in the art, and can be flexibly adjusted by those skilled in the art on the premise of knowing the purpose of setting; to avoid redundancy, the following will only be described by taking the setting up of the first guide wheel 14 and the passive wheel 15 as an example:

Specifically, a vertical plate 19 is respectively provided on the front and rear sides of the first guide wheel 14, the vertical plates 19 are fixed on the fixed seat 3, and bearing members (not shown in the figure) are embedded thereon; an axis member is arranged along the front and rear directions, and its two ends are respectively inserted into the inner rings of the bearing members on each vertical plate 19, and at the same time, the part located between the two vertical plates 19 is fixedly connected to the first guide wheel 14; when the first pulling member 71 moves driven by the driving wheel 41, the first guide wheel 14 will be driven by the first pulling member 71 due to the matching relationship between the first pulling member 71 (that is, the matching relationship between the gear belt and the gear), and rotate along the movement direction of the first pulling member 71.

Furthermore, the front end of the aforementioned shaft extends out of the vertical plate 19 located on the front side of the first guide wheel 14, penetrates into the passive wheel 15 and is fixedly connected to the passive wheel 15, so that when the first guide wheel 14 is driven by the first pulling member 71 and rotates, the first guide wheel 14 can synchronously drive the passive wheel 15 to rotate.

Based on the above structure, when the first movable member 51 and the second movable member 52 of this embodiment move to the highest point as shown in Figure 6, that is, the first elastic member 9 and the second elastic member 13 are in contact with the upper edges of their respective corresponding guide grooves and are in a stretched state, a portion of the first pulling member 71 is wound up on the driving wheel 41, and a portion of the second pulling member 72 is wound up on the passive wheel 15. The first pulling member 71 and the second pulling member 72 are in a taut state. The first pulling member 71 lifts the first movable member 51, and the second pulling member 72 lifts the second movable member 52 to maintain the first movable member 51 and the second movable member 52 at this time. The height remains unchanged. Based on this, the driving wheel 41 is then rotated in the direction of releasing the (retracted) first pulling member 71, and the driving wheel 41, the first guide wheel 14, the second guide wheel 16, the passive wheel 15, the third guide wheel 17 and the fourth guide wheel 18 will all rotate in the direction of the arrow shown in Figure 6, and the passive wheel 15 will release the retracted second pulling member 72. The first pulling member 71 will no longer apply a force sufficient to position the first moving member 51 at the highest point of its stroke, and the second pulling member 72 will no longer apply a force sufficient to position the second moving member 52 at the highest point of its stroke. The first moving member 51 and the second moving member 52 will move downward under the elastic restoring force of the first elastic member 9 and the second elastic member 13, respectively.

In this way, when the first movable member 51 and the second movable member 52 are located at the highest points of their respective travels, the retracted lengths of the first pulling member 71 and the second pulling member 72 are configured to be sufficient to enable the first movable member 51 and the second movable member 52 to descend to the lowest points of their respective travels, and the up and down movements of the first movable member 51 and the second movable member 52 can be controlled by controlling the rotation angle and rotation direction of the driving wheel 41. That is, in addition to the above-mentioned process of making the first movable member 51 and the second movable member 52 descend from the highest point, on the contrary, when the first movable member 51 and the second movable member 52 are both located at the lowest point of their travels, the first movable member 51 is supported by the base 2, and the second movable member 52 is supported by the second stop beam 515, so that the driving wheel 41 rotates in a direction opposite to the direction of the arrow shown in Figure 6, so as to retract the first pulling member 71, and at the same time drive the passive wheel 15 to retract the second pulling member 72, so that the first pulling member 71 and the second pulling member 72 gradually lift up the first movable member 51 and the second movable member 52 until the first functional rod 11 and the second functional rod 12 respectively reach the apex of the first guide groove 33 and the second guide groove 5111.

Preferably, in this embodiment, the vertices of the first guide groove 33 and the second guide groove 5111 are configured so that when the first functional rod 11 and the second functional rod 12 reach the vertices of the first guide groove 33 and the second guide groove 5111 respectively, the first guide wheel 14 and the second guide wheel 16 are almost at the same height, and the third guide wheel 17 and the fourth guide wheel 18 are almost at the same height.

Please further refer to Figures 8 and 9. As mentioned above, during the upward movement of the second moving member 52, it will naturally drive the force-applying member 6 fixedly connected to itself to apply force to the screen 10, thereby realizing the rotation of the screen 10. A more detailed description of this setting is that the force-applying member 6 is specifically T-shaped, with the end with a larger diameter facing downward and the end with a smaller diameter facing upward, and the end with a larger diameter lies between the two second hooking portions 521 of the second moving member 52 and is fixedly connected to the two second hooking portions 521; optionally, the specific method of the fixed connection can be one-piece molding, interference fit, or welding.

Based on the above, the rotatable display screen assembly also includes a first rotating shaft 20 and two first connecting members 21, both of which are located on the lower left side of the screen 10, wherein the two first connecting members 21 are arranged on the lower side of the screen 10 at intervals from each other and are fixedly connected to the screen 10; the first rotating shaft 20 is located on the lower side of the screen 10, and is passed through the upward end of the force-applying member 6, and is rotatably connected to the force-applying member 6; at the same time, the two ends of the first rotating shaft 20 also pass through the force-applying member 6 respectively, and are fixedly connected to the first connecting member 21.

Thus, under the premise of the aforementioned support assembly 8, when the second moving member 52 moves upward, the second moving member 52 will drive the force applying member 6 to apply an upward force to the first rotating shaft 20; similarly, when the second moving member 52 moves downward, it will drive the force applying member 6 to apply a downward force to the first rotating shaft 20. Thus, when the second moving member 52 moves upward, the left end of the screen 10 will move upward relative to the right end thereof, and vice versa when the second moving member 52 moves downward, the left end of the screen 10 will move downward relative to the right end thereof.

It should be noted that, based on the above description, it is easy to know that those skilled in the art can also only set one moving member 5 between the fixed seat 3 and the screen 10, and cancel the second moving member 52, the second pulling member 72, the passive wheel 15, the third guide wheel 17 and the fourth guide wheel 18, and fix the force-applying member 6 on the first moving member 51; in this way, the scheme can also achieve the effect of rotating the screen 10 by making the first moving member 51 move up and down, thereby driving the force-applying member 6 to apply force to the screen 10. Similarly, those skilled in the art can also flexibly set the number of moving members 5 and pulling members 7 as needed.

Please further refer to Figures 9 and 10. The aforementioned support assembly 8 specifically includes a support rod 81, a second rotating shaft 82 and a second connecting member 83 located at the lower side of the screen 10, wherein the support rod 81 is arranged in the up-down direction, the lower end of the support rod 81 is fixedly connected to the base 2, and the upper end is spaced apart from the screen 10; the two second connecting members 83 are fixed on the lower surface of the screen 10 at intervals from each other, and the second rotating shaft 82 is arranged in the front-to-back direction, the second rotating shaft 82 is rotatably passed through the upper end of the support rod 81, and its front and rear ends are respectively fixedly connected to the two second connecting members 83; in this way, when the screen 10 is subjected to the force of the force-applying member 6 and then rotates, the support rod 81 and the second rotating shaft 82 are equivalent to forming a fulcrum, and the second rotating shaft 82 will be driven to rotate relative to the support rod 81, so that the support assembly 8 will not hinder the rotation of the screen 10 while supporting the screen 10.

Furthermore, in the present embodiment, a matching hole 811 is provided in the middle and upper part of the support rod 81, and the support assembly 8 also includes an arc-shaped follower 84, which is passed through the matching hole 811, and has no movement margin between the follower 84 and the support rod 81 in the front-to-back direction, and the follower 84 can pass through the matching hole 811; the opening of the follower 84 faces the screen 10, and its two ends are respectively located on the left and right sides of the support rod 81 and are fixedly connected to the lower surface of the screen 10; the follower 84 can rotate with the screen 10 when the screen 10 is driven to rotate, and move relative to the support rod 81.

As mentioned above, the purpose of setting the follower 84 is to determine the rotation trajectory of the screen 10; more specifically, since the first rotating shaft 20 and the second rotating shaft 82 are rotatably connected to the force-applying member 6 and the support rod 81 respectively, the first rotating shaft 20 and the second rotating shaft 82 are easily displaced in the front-to-back direction relative to the force-applying member 6 and the support rod 81. After providing the follower 84 which obviously has a snap-fitting relationship with the support rod 81 in the front-to-back direction, there is no need to worry about the problem of the first rotating shaft 20 and the second rotating shaft 82 moving along the front-to-back direction.

Preferably, the contour of the follower 84 is semicircular; more preferably, the matching hole 811 is a shape imitating the shape of the follower 84. Further, in this embodiment, a groove-shaped track 841 is provided on the follower 84 along its direction, and correspondingly, a protrusion (not shown) imitating the shape of the track 841 is provided on the inner wall of the matching hole 811. When the matching hole 811 of the support rod 81 and the follower 84 cannot be well matched due to production errors, the assembly fit between the two can be fine-tuned by sticking a gasket on the protrusion or cutting the protrusion.

In summary, by arranging the screen 10, the driving assembly 4, the force-applying member 6 and the supporting assembly 8, the screen 10 is supported by the supporting assembly 8 and the supporting assembly 8 will not hinder the rotation of the screen 10. At the same time, the screen 10 can be rotated by the force-applying member 6. The present invention can provide a display screen assembly with a rotatable screen, which has the advantages of simple structure, easy operation and the ability to enhance the viewer experience.

Furthermore, when the display screen assembly is actually placed in an application scenario and its actual up and down direction is consistent with the up and down direction in the aforementioned drawings, if the first movable member 51 and the second movable member 52 need to move downward, the downward movement of the first movable member 51 and the second movable member 52 can be completed with the aid of gravity. At this time, whether to set the first elastic member 9, the first functional rod 11, the second elastic member 13, the second functional rod 12 and other components can be flexibly set by technical personnel in this field.

It should be noted that when the display screen assembly is actually placed in an application scenario, the angle of the screen 10 when the first movable member 51 and the second movable member 52 are both moved upward to the highest point of their travel can be used as the initial angle of the screen 10, or the angle of the screen 10 when the first movable member 51 and the second movable member 52 are both located at the lowest point of their travel can be used as the initial angle of the screen 10; these can be flexibly adjusted according to the design needs of technical personnel in this field.

Optionally, since the driving motor needs to rotate in two completely opposite directions when the first moving member 51 and the second moving member 52 are moved upward and downward, which is equivalent to forward rotation and reverse rotation, respectively, the control logic scheme for switching the driving motor between forward and reverse rotation can be set as follows:

A switch is provided for indicating that the drive motor needs to be reversed for the operator to use. When the first movable member 51 and the second movable member 52 move upward to the highest point of the travel, the operator presses the switch, and the drive motor will be overloaded first, causing the internal safety control element (such as a current relay) to stop the forward contactor from working, and then the reverse contactor to work, thereby causing the drive motor to switch from the forward state to the reverse state. It should be noted that the forward contactor, the reverse contactor, the current relay, etc. are all commonly used devices in motor engineering, and their specific structures and working principles will not be described in detail in this article.

Furthermore, the present invention also provides a vehicle, which includes the aforementioned display screen assembly with a rotatable screen. When the display screen assembly is applied to the vehicle, since the screen 10 is rotatable, the passengers can adjust the posture of the screen 10 according to their own needs, which is undoubtedly conducive to the passengers having a good riding experience.

Furthermore, the display screen assembly in the vehicle is arranged on the dashboard assembly of the passenger compartment and is fixedly connected to the dashboard assembly. At this time, at least the screen 10 in the display screen assembly is exposed to the interior of the passenger compartment. The screen 10 is located on the rear side of the fixed seat 3 and faces the rear of the vehicle, thereby providing corresponding display functions for the passengers.

Preferably, when the first functional rod 11 and the second functional rod 12 are respectively moved to the midpoint of the first guide groove 33 and the second guide groove 5111, the screen 10 is parallel to the Z direction of the actual vehicle; when the first functional rod 11 and the second functional rod 12 are respectively moved to any end of the first guide groove 33 and the second guide groove 5111, an angle of 40° is formed between the screen 10 and the Z direction of the actual vehicle.

Optionally, corresponding software and controllers can be set so that the occupant can adjust the driving assembly 4 by touching the screen 10, thereby adjusting the posture of the screen 10. Optionally, corresponding software can also be developed so that the occupant can pre-check and set the initial angle of the display screen assembly when it is working as needed; the initial angle can be multiple, for example, the occupant can record the first angle, the second angle and the third angle in the software, and then select any one of these initial angles according to different needs at different times.

Of course, the application prospects based on this display screen assembly also include developing corresponding software and setting a camera on the screen 10 to capture the face. By identifying the angle between the face and the camera and assisted by software judgment, the vehicle can automatically adjust the posture of the screen 10 according to the position of the occupants, thereby improving the intelligence level of the vehicle. Furthermore, the automatic judgment logic can also introduce voice to adjust and confirm the screen posture.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
