[0045] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0046] The embodiments of the present application provide a display screen structure. Please refer to Figure 1 ., including a display screen main body 1 and a first driving device 2. Among them, the display screen main body 1 includes a display screen 11 and a pitch adjustment structure 12, and the display screen 11 is connected to the pitch adjustment structure 12. The first driving device 2 is drivingly connected to the pitch adjustment structure 12 to drive the pitch adjustment structure 12 to adjust the pitch angle of the display screen 11. The first driving device 2 is drivingly connected to the pitch adjustment structure 12, so that the pitch angle of the display screen 11 can be adjusted, the flexibility of the display screen 11 is increased, and it can adapt to the needs in different scenarios, improving the viewing effect.

[0047] Among them, the first driving device 2 is flexibly drivingly connected to the pitch adjustment structure 12. By connecting the first driving device 2 and the pitch adjustment structure 12 in a flexible driving connection manner, there is a certain elasticity and deformability between the first driving device 2 and the pitch adjustment structure 12, and the pitch of the display screen 11 can be manually fine-tuned, and there will be no direct mechanical impact or damage to the first driving device 2 during the fine-tuning process, improving the accuracy and convenience of adjusting the pitch angle of the display screen 11.

[0048] In some embodiments, please refer to Figure 1 and Figure 2, the pitch adjustment structure 12 includes a first rotating shaft 122 and a connecting portion 121, and the first driving device 2 includes a first driving motor 21 and a driving belt 22. Among them, the connecting portion 121 is connected to the display screen 11, the first rotating shaft 122 is connected to the connecting portion 121, and the first driving motor 21 is drivingly connected to the first rotating shaft 122 through the driving belt 22 to drive the display screen 11 to rotate around the axis direction of the first rotating shaft 122.

[0049] The connecting portion 121 can connect the first rotating shaft 122 and the display screen 11 to form an integral body, so that when the first rotating shaft 122 rotates, it can drive the display screen 11 to rotate, thereby realizing the adjustment of the pitch angle of the display screen 11. The first driving device 2 includes a first driving motor 21 and a driving belt 22. The first driving motor 21 can provide driving force, and the driving belt 22 can realize the flexible driving connection between the first driving motor 21 and the first rotating shaft 122, so that the first driving motor 21 drives the first rotating shaft 122 to rotate, and then drives the display screen 11 to rotate, realizing the adjustment of the pitch angle of the display screen 11. And because the driving belt 22 has certain elasticity and deformability, the position of the display screen 11 can also be directly manually adjusted to realize the fine adjustment of the pitch angle, and no direct mechanical impact or damage will be caused to the first driving motor 21 during the fine adjustment process.

[0050] Exemplarily, please refer to Figure 2 , a driven wheel 1221 is provided at one end of the first rotating shaft 122, a driving wheel (not shown in the figure) is provided on the motor shaft of the first driving motor 21, and the driving belt 22 is sleeved on the driven wheel 1221 and the driving wheel. When the first driving motor 21 rotates, it drives the driving wheel to rotate, and then drives the driven wheel 1221 to rotate through the driving belt 22, so that the display screen 11 rotates around the first rotating shaft 122, realizing the adjustment of the pitch angle.

[0051] In some embodiments, please refer to Figure 1 , the display screen structure further includes a display screen bracket 3. The first rotating shaft 122 is rotatably connected to the display screen bracket 3, and the first driving motor 21 is arranged on the display screen bracket 3. The display screen bracket 3 can support the display screen main body 1. The first rotating shaft 122 is rotatably connected to the display screen bracket 3, which is convenient for adjusting the pitch angle of the display screen main body 1.

[0052] In some embodiments, the display screen support 3 includes a bottom plate 31 and a support frame 32 fixedly arranged on the bottom plate 31. The first rotating shaft 122 is rotatably connected to the support frame 32, and the first driving motor 21 is arranged on the bottom plate 31. Among them, the bottom plate 31 can ensure the stability of the support and disperse the pressure of the display body. The support frame 32 is rotatably connected to the first rotating shaft 122, which can support the display screen body 1 while facilitating the rotation of the first rotating shaft 122 to realize the pitching angle adjustment of the display screen 11. The first driving motor 21 is arranged on the bottom plate 31 to fix the first driving motor 21.

[0053] Exemplarily, please refer to Figure 3 , the support frame 32 includes two connecting ears arranged in the horizontal direction. Both ends of the first rotating shaft 122 are respectively sleeved in the two connecting ears, and the first rotating shaft 122 is rotatably connected to the connecting ears. When the first driving motor 21 drives the first rotating shaft 122 to rotate, the first rotating shaft 122 can rotate relative to the connecting ears and drive the display screen 11 connected to the first rotating shaft 122 to rotate, thereby realizing the pitching angle adjustment of the display screen 11.

[0054] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 , the display screen structure further includes a deflection adjustment structure 4 and a second driving device 5. The deflection adjustment structure 4 is fixedly connected to the display screen support 3, and the second driving device 5 is drivingly connected to the deflection adjustment structure 4 to drive the display screen support 3 to rotate around a vertical axis perpendicular to the first rotating shaft 122.

[0055] Through the deflection adjustment structure 4, the deflection angle adjustment of the display screen 11 can be realized, so that the display screen structure can meet the requirements in different scenarios. For example, when the display screen structure is used as a vehicle-mounted central control screen, since the vehicle-mounted central control screen is usually arranged between the driver's seat and the passenger seat to take into account the viewing of both the driver and the passenger, through the deflection adjustment structure 4, the deflection of the display screen 11 can be realized, so that the display screen 11 tilts towards the driver or the passenger, switching different viewing angles and improving the viewing effect. The second driving device 5 is drivingly connected to the deflection adjustment structure 4 to improve the degree of automation.

[0056] In some embodiments, please refer to Figure 3 and Figure 4 , the deflection adjustment structure 4 includes a second rotating shaft 41. One end of the second rotating shaft 41 is fixedly connected to the bottom plate 31, and the other end of the second rotating shaft 41 is drivingly connected to the second driving device 5. That is, one end of the second rotating shaft 41 is fixedly connected to the bottom plate 31. When the second rotating shaft 41 rotates, it can drive the bottom plate 31 to rotate, and then drive the support frame 32 arranged on the bottom plate 31 and the display screen body 1 arranged on the support frame 32 to rotate, thereby realizing the deflection angle adjustment of the display screen 11.

[0057] In some embodiments, referring to Figure 4 , the second driving device 5 includes a driving mechanism 51 and a rack 54, and the driving mechanism 51 is drivingly connected to the rack 54. One end of the second rotating shaft 41 away from the bottom plate 31 is provided with a deflection gear 42, and the rack 54 meshes with the deflection gear 42. The driving mechanism 51 drives the rack 54 to move, so that the rack 54 drives the deflection gear 42 to rotate around the second rotating shaft 41.

[0058] Among them, the driving mechanism 51 can be a telescopic cylinder, a telescopic oil cylinder or a driving motor, and the driving mechanism 51 drives the rack 54 to move back and forth. Since the rack 54 meshes with the deflection gear 42, the rack 54 drives the deflection gear 42 to rotate around the second rotating shaft 41 during the back-and-forth movement, and the second rotating shaft 41 also rotates, thereby driving the bottom plate 31 and the support frame 32 to rotate, and the support frame 32 drives the rotation of the display screen main body 1, realizing the adjustment of the deflection angle of the display screen 11.

[0059] In some embodiments, referring to Figure 4 , the driving mechanism 51 is a second driving motor. The second driving device 5 further includes a driving screw 52 and a threaded tube 53. Among them, one end of the driving screw 52 is drivingly connected to the second driving motor, the other end of the driving screw 52 is nested in the threaded tube 53 and is threadedly connected to the threaded tube 53, and the rack 54 is sleeved on the periphery of the threaded tube 53. The second driving motor drives the driving screw 52 to rotate in the axial direction, the driving screw 52 drives the threaded tube 53 to move along the axis of the driving screw 52, the threaded tube 53 drives the rack 54 to move along the axis of the driving screw 52, and the rack 54 drives the deflection gear 42 to rotate around the second rotating shaft 41.

[0060] When the second driving motor works, it can drive the driving screw 52 to rotate. Since the driving screw 52 is threadedly connected to the threaded tube 53, when the driving screw 52 rotates, it can drive the threaded tube 53 to move along its axis, and then drive the rack 54 sleeved on the periphery of the threaded tube 53 to move. The rack 54 meshes with the deflection gear 42. When the rack 54 moves along the axis of the threaded tube 53, it can drive the deflection gear 42 to rotate, so that the display screen 11 deflects.

[0061] In some embodiments, referring to Figure 1 , Figure 3 and Figure 5, the display screen structure further includes a base 6. The display screen bracket 3 and the second driving device 5 are respectively arranged on opposite sides of the base 6. The second rotating shaft 41 passes through the base 6 and is movably connected to the base 6. Through the base 6, the fixation and support of the display screen structure can be realized, ensuring the stability of the display screen structure. By arranging the display screen bracket 3 and the second driving device 5 on opposite sides of the base 6 respectively, while the display screen 11 can be rotated and adjusted, the second driving device 5 can be covered by the base 6, improving the overall aesthetics. Moreover, since the second driving device 5 is located at the bottom of the base 6, the stability can also be improved. The second rotating shaft 41 passes through the base 6 and is movably connected to the base 6. When the second driving device 5 drives the second rotating shaft 41 to rotate, the base 6 does not rotate, while the display screen bracket 3 will rotate along with the second rotating shaft 41, thereby driving the display screen 11 to rotate and realizing the adjustment of the deflection angle of the display screen 11.

[0062] Exemplarily, please refer to Figure 3 and Figure 4 , the bottom of the base 6 has a receiving cavity, and the second driving device 5 is arranged in the receiving cavity, which can save the layout space. The second rotating shaft 41 and the base 6 are connected by a bearing 7, and the bearing 7 is sleeved around the second rotating shaft 41 to realize the movable connection between the second rotating shaft 41 and the base 6.

[0063] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 , a threading hole is provided in the second rotating shaft 41 and runs through the second rotating shaft 41 along its axis direction. By providing the threading hole in the second rotating shaft 41, it is convenient for the wire harness to pass through. For example, the video signal line connected to the display screen 11 and the wire harness connected to the first driving device 2.

[0064] In some embodiments, please refer to Figure 3 and Figure 4 , the display screen structure further includes a controller 8. The controller 8 is electrically connected to the first driving device 2 and / or the second driving device 5, and the controller 8 is configured to control the first driving device 2 and / or the second driving device 5.

[0065] The controller 8 can realize the precise adjustment of the first driving device 2 and / or the second driving device 5, which is convenient for improving the degree of automation.

[0066] Exemplarily, please refer to Figure 3 and Figure 4, the controller 8 includes a first controller 81 and a second controller 82. Among them, the first controller 81 is electrically connected to the first driving device 2 and is used to control the first driving device 2. The second controller 82 is electrically connected to the second driving device 5 and is used to control the second driving device 5. By setting the first controller 81 and the second controller 82, independent control of the first driving device 2 and the second driving device 5 can be achieved, improving the control accuracy. And when one of the controllers 8 or the driving devices fails, it will not affect the other controller 8 or the driving device. Through the mutual cooperation of the two controllers 8 and the driving devices, more working modes can be achieved, which are applicable to different application scenarios.

[0067] In some embodiments, please refer to Figure 5 , the display screen structure further includes a control button 9. The control button 9 is electrically connected to the controller 8 to control the first driving device 2 and / or the second driving device 5. Since the control button 9 is electrically connected to the controller 8, when the control button 9 is operated, corresponding control instructions can be sent to the controller 8, and then the controller 8 can control the first driving device 2 and / or the second driving device 5 to work, simplifying the adjustment method of the display screen structure and improving the flexibility and reliability of the adjustment.

[0068] Exemplarily, please refer to Figure 5 , the control button 9 includes two groups. One group is the pitch control button 91, and the other group is the rotation control button 92. Among them, the pitch control button 91 is electrically connected to the first controller 81, and the first controller 81 is electrically connected to the first driving device 2.

The rotation control button 92 is electrically connected to the second controller 82, and the second controller 82 is electrically connected to the second driving device 5. By operating the rotation control button 92, the deflection angle adjustment of the display screen 11 can be achieved.

[0069] In some embodiments, please refer to Figure 3 and Figure 4 , the display screen structure further includes a power supply unit 10. The power supply unit 10 is electrically connected to the controller 8, the first driving device 2, and the second driving device 5.
