[0057] 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 fall within the protection scope of the present application.

[0058] The present application provides a display screen assembly 10. Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of the display screen assembly provided in an exemplary embodiment of the present disclosure, Figure 2 is Figure 1 A schematic structural diagram of the display screen assembly shown (at an angle). The display screen assembly 10 includes a base 1, a monitor main body 2, a transmission component 3, and a linear drive component 4. The monitor main body 2 has a rotation shaft 21, and the rotation shaft 21 is rotatably installed on the base 1. The transmission component 3 includes a gear 31 and a rack 32 meshing with the gear 31. The gear 31 is sleeved on the rotation shaft 21 and rotates synchronously with the rotation shaft 21. The linear drive component 4 is installed on the base 1, and the linear drive component 4 is used to drive the rack 32 to move along its length direction.

[0059] In the display screen assembly 10 of the embodiment of the present application, the rack 32 is driven to move by the linear drive assembly 4, thereby driving the gear 31 and the rotating shaft 21 to rotate, so that the display body 2 can be adjusted at multiple angles. This design allows users to easily adjust the angle of the display according to viewing needs or personal comfort, and obtain a better viewing experience. The meshing design of the gear 31 and the rack 32 ensures the stability during the rotation process, avoiding the decline of the viewing experience or equipment damage caused by shaking or instability. Users can adjust the angle of the display without complex operations, improving the convenience of use. The cooperation of the gear 31 and the rack 32 makes the structure of the display screen assembly 10 simple and compact, which can save installation space to a certain extent, reduce the processing difficulty, and save costs.

[0060] Refer to Figure 2 and Figure 3 , Figure 3 is Figure 2 The partial enlarged schematic diagram of the position A shown in the figure. In some embodiments, the linear drive assembly 4 includes a drive motor 41, a lead screw 42 and a nut 43. The drive motor 41 is installed on the base 1. The drive motor 41 has a drive shaft 411 extending along the length direction of the rack 32. The lead screw 42 extends along the length direction of the rack 32. One end of the lead screw 42 is connected to the drive shaft 411. The nut 43 is sleeved on the lead screw 42 and is threadedly connected to the lead screw 42. The nut 43 is connected to the rack 32. In this way, by accurately controlling the rotation of the lead screw 42 by the drive motor 41, the high-precision movement of the nut 43 along the lead screw 42 can be realized, and then the movement of the rack 32 can be accurately controlled, so as to realize the rotation of the gear 31 driven by the rack 32 and then realize the accurate adjustment of the angle of the display body 2. The transmission of the lead screw 42 and the nut 43 has a self-locking characteristic. When the motor stops running, it can keep the current position unchanged and prevent the display body 2 from rotating accidentally. The transmission of the lead screw 42 and the nut 43 has a high transmission efficiency, which can effectively transmit the power of the drive motor 41 to the rack 32 and the display body 2, reducing energy loss. The drive motor 41 can quickly respond to control signals to realize the quick adjustment of the display body 2 and improve the user experience. Since the lead screw 42 extends along the length direction of the rack 32, the whole linear drive assembly 4 has a compact structure and small occupied space, which is beneficial to the overall design and miniaturization of the display screen assembly 10. The transmission structure of the lead screw 42 and the nut 43 is stable and reliable, not easy to fail, and improves the overall reliability of the display screen assembly 10. Since the linear drive assembly 4 has a compact structure and simple component connection, when it is necessary to replace or repair the linear drive assembly 4, the operation can be carried out conveniently, reducing the maintenance cost.

[0061] It should be noted that in other embodiments, the linear drive assembly 4 may further include a linear motor, an electric push rod, a cylinder, or a hydraulic cylinder, etc. The type of the linear drive assembly 4 can be set according to needs, and the present application does not limit this. Additionally, according to the tooth ratio of the rack 32 and the gear 31, the gear 31 can be deflected by plus or minus 45 degrees. Of course, in other embodiments, the deflection angle of the gear 31 can be set according to the tooth ratio of the rack 32 and the gear 31. Specifically, the present application does not limit this.

[0062] Referring to Figure 3 , in one embodiment, the rack 32 and the lead screw 42 are kept parallel in the same horizontal plane, and the axis of the nut 43 is kept parallel to the rack 32 in the same horizontal plane for transmission. In this way, the parallelism of the rack 32 and the lead screw 42 in the same horizontal plane can ensure more stable contact between components during the transmission process, reducing energy loss. Keeping parallel can reduce the friction between the rack 32 and the lead screw 42, thereby reducing wear and extending the service life. Since the rack 32, the lead screw 42, and the nut 43 are kept parallel in the same horizontal plane, the movement accuracy of the display body 2 can be improved, and the deviation can be reduced. The parallel design makes the structure of the entire transmission assembly 3 simpler, simplifying the design and manufacturing process. Since the rack 32, the lead screw 42, and the nut 43 are kept parallel in the same horizontal plane, the installation and adjustment processes become simpler, reducing the requirement for precise alignment. By keeping parallel in the same horizontal plane, space can be utilized more effectively, making the entire mechanical structure more compact.

[0063] Referring to Figure 3 and Figure 5 , Figure 5 is Figure 1 the cross-sectional schematic view of the display screen assembly shown. In some embodiments, the display screen assembly 10 further includes a guiding structure. The guiding structure includes a guiding portion 51 extending along the length direction of the rack 32 and a mating portion 52 adapted to the guiding portion 51. One of the guiding portion 51 and the mating portion 52 is provided on the rack 32, and the other is provided on the base 1. In this way, the guiding structure provides an accurate guiding path for the relative movement between the rack 32 and the base 1, ensuring that the rack 32 does not deviate from the predetermined trajectory during movement, thereby improving the overall stability of the display screen assembly 10. During the movement of the rack 32, the guiding structure can effectively reduce the vibration and shaking generated due to the movement, ensuring the smooth display of the display screen image.

[0064] Continuing to refer to Figure 3 and Figure 5In some embodiments, the guide portion 51 is provided on the rack 32 and includes a guide groove. The matching portion 52 is provided on the base 1 and includes a protrusion. The protrusion is provided along the axial direction of the rotating shaft 21 and is slidably installed in the guide groove. In this way, it can be ensured that the rack 32 moves along a predetermined path, thereby ensuring that the entire transmission assembly 3 moves accurately and stably. The relative sliding of the protrusion in the guide groove can limit the relative freedom of movement between the base 1 and the rack 32, and only allow the rack 32 to move linearly in a specific direction, so that unnecessary shaking or deviation of the rack 32 can be avoided. The matching installation of the protrusion and the guide groove makes the assembly process simpler and more direct, because it only needs to align the protrusion with the guide groove and insert it.

[0065] It should be noted that there are many types of guide portion 51 and matching portion 52. For example, in one embodiment, guide portion 51 may further include a guide rod, and matching portion 52 may include a guide hole. In other embodiments, in some embodiments, guide portion 51 may further include a guide rail, and matching portion 52 is a sliding block 521. The specific selection of guide portion 51 and matching portion 52 can be set as needed, and this application does not limit this.

[0066] Reference Figure 5 In some embodiments, the guide groove is arranged through the rack 32 along the axial direction of the rotating shaft 21, and the protrusion includes a sliding block 521 and a stop block 522 connected in sequence along the axial direction of the rotating shaft 21. The end of the sliding block 521 away from the stop block 522 passes through the guide groove and is connected to the base 1. Along the width direction of the rack 32, the width of the guide groove is less than the width of the stop block 522. In this way, the width of the stop block 522 is greater than the width of the guide groove, which can prevent the sliding block 521 from completely leaving the guide groove, thereby limiting the range of motion of the sliding block 521 and ensuring that the sliding block 521 can only slide in the guide groove. The guide groove provides a guiding function for the sliding block 521, ensuring that the sliding block 521 can move along the expected path relative to the guide groove. Since the width of the guide groove is less than the width of the stop block 522, the rack 32 is constrained in the thickness direction, so that the rack 32 is flush with the gear 31 in thickness, so that the rack 32 reciprocates along the tangent direction of the gear 31, thereby improving the stability of the transmission assembly 3. The sliding block 521 can pass through the guide groove and be connected to the base 1, which simplifies the assembly process. The sliding block 521 only needs to be aligned with the guide groove and then inserted to complete the assembly.

[0067] Reference Figure 2 and Figure 5, in some embodiments, an installation space 11 is formed on one side of the base 1 facing away from the display body 2. The base 1 is further provided with an installation hole 12 communicating with the installation space 11. The installation hole 12 extends along the axial direction of the rotation shaft 21. The rotation shaft 21 is rotatably installed in the installation hole 12. The transmission component 3 and the linear drive component 4 are both installed in the installation space 11. In this way, the installation space 11 is formed inside the base 1, which can effectively utilize the limited space to accommodate the transmission component 3 and the linear drive component 4, making the structure of the entire display screen assembly 10 more compact. The installation hole 12 communicates with the installation space 11, enabling the rotation shaft 21 to pass through the installation hole 12 and extend into the installation space 11, facilitating the sleeving of the gear 31 on the rotation shaft 21, with a simple structure and easy operation. Installing the transmission component 3 and the linear drive component 4 in the installation space 11 inside the base 1 can effectively protect these components from the external environment, such as dust, water vapor, etc., and extend their service life. Since the transmission component 3 and the linear drive component 4 are both in the same installation space 11, the connection becomes simpler, improving the aesthetic appearance of the display screen assembly 10. The transmission component 3 and the linear drive component 4 are firmly installed inside the base 1, which helps to improve the stability of the entire display screen assembly 10.

[0068] Referring to Figures 2 to 4 , Figure 4 is Figure 1 a schematic structural diagram of the display screen assembly (from another angle) shown in the figure. In some embodiments, the base 1 includes a support plate 13 and a surrounding frame 14. The support plate 13 is provided with an installation hole 12. The support plate 13 is used to support the display body 2. The surrounding frame 14 is arranged on the side of the support plate 13 facing away from the display body 2 and is connected to the support plate 13. The surrounding frame 14 and the support plate 13 jointly enclose to form the installation space 11. In this way, the combination of the support plate 13 and the surrounding frame 14 can improve the overall structural stability of the base 1, ensuring that it is not easily deformed or damaged when carrying the display body 2. The installation space 11 formed by the surrounding frame 14 and the support plate 13 can effectively protect the transmission component 3 and the linear drive component 4 from the external environment. The design of the installation space 11 makes the installation and maintenance of the transmission component 3 and the linear drive component 4 more convenient and fast, without the need for a complex disassembly process. The space formed by the surrounding frame 14 and the support plate 13 together can efficiently utilize the internal space of the base 1, reducing the occupied volume. The closed installation space 11 design can hide the internal components, making the appearance of the display screen assembly 10 more concise and beautiful. Through the enclosure of the surrounding frame 14, users can be prevented from contacting the internal transmission component 3 and linear drive component 4, reducing the risk of electric shock or mechanical injury. The design of the installation space 11 facilitates regular cleaning and maintenance, extending the service life of the display screen assembly 10.

[0069] It should be noted that, in other embodiments, the base 1 also includes a cover plate, which is arranged opposite to the support plate 13 and is detachably connected to the periphery of the other end of the enclosure frame 14 away from the support plate 13, so that the cover plate can completely close the installation space 11 and protect the internal transmission assembly 3 and the linear drive assembly 4 from the external environment. The completely enclosed structure can prevent the user from accidentally contacting the internal electrical or mechanical components, reducing the risk of electric shock or mechanical injury. Through the design of the cover plate, the installation space 11 can be easily opened or closed, which is convenient for maintenance personnel to carry out inspection and maintenance work. The design of the cover plate can make the appearance of the base 1 more neat, hide the internal mechanical and electrical components, and improve the overall aesthetics of the display screen assembly 10. The cover plate is connected to the enclosure frame 14 to increase the overall structural strength of the base 1, making it more solid and stable.

[0070] Reference Figure 5 In some embodiments, the enclosure frame 14 includes a first frame segment 141 and a second frame segment 142 which are opposite to and spaced apart from each other in the front-to-back direction of the display body 2. The first frame segment 141 is located at the front side of the display body 2. The projection of the second frame segment 142 is located within the projection of the second frame segment 142 in the front-to-back direction of the display body 2. The transmission assembly 3 and the linear drive assembly 4 are arranged adjacent to the first frame segment 141. In this way, while ensuring the installation of the transmission assembly 3 and the linear drive assembly 4, the installation space 11 can be reduced as much as possible, so that the base 1 has a compact structure.

[0071] Reference Figure 1 In some embodiments, the display screen assembly 10 further includes a forward offset switch 61 and a reverse offset switch 62, which are mounted on the first frame section 141, so that the user can operate them conveniently. The forward offset switch 61 and the reverse offset switch 62 are arranged at intervals along the left and right directions of the display body 2, so that the forward offset switch 61 and the reverse offset switch 62 are prevented from interfering with each other, so that the user can directly control the moving direction of the display screen by pressing the forward offset switch 61 and the reverse offset switch 62, and the operation is more intuitive.

[0072] Reference Figure 2, in some embodiments, the display screen assembly 10 further includes a power supply 7 and a controller 8 which are electrically connected. The power supply 7 and the controller 8 are both installed in the installation space 11. The controller 8 is electrically connected to the forward offset switch 61, the reverse offset switch 62 and the linear drive assembly 4. In this way, installing the power supply 7 and the controller 8 in the installation space 11 can facilitate the centralized management and maintenance of these electronic components. Since all relevant components are located in the installation space 11, the internal wiring can be simplified, the cable clutter can be reduced, and the overall aesthetics can be improved. The controller 8 is electrically connected to the forward offset switch 61, the reverse offset switch 62 and the linear drive assembly 4, which can achieve a quick response to user operations and improve the user experience. The centralized design can reduce the possibility of line failures and improve the overall reliability of the display screen assembly 10. By installing the power supply 7 and the controller 8 in the enclosed installation space 11, the risk of users coming into contact with these components can be reduced and the safety can be improved. Installing the power supply 7 and the controller 8 in the installation space 11 can make more effective use of space and make the overall design more compact.

[0073] It should be noted that the controller 8 is an electronic device for controlling the forward offset switch 61, the reverse offset switch 62 and the linear drive assembly 4 in the display screen assembly 10. The model selection of the controller 8 depends on factors such as specific application requirements, the complexity of the control logic, and the power supply 7 requirements. The following are some possible categories of controller 8 models: For example, the controller 8 may include a microcontroller 8 unit (MCU) or a digital signal controller 8 (DSC). The microcontroller 8 unit is a microcomputer integrated on a single chip, usually including a central processing unit (CPU), memory, and interfaces 15 for input / output (I / O) functions. Common microcontroller 8 models include: Arduino series, STM32 series, ESP32 / ESP8266, RaspberryPiPico. The digital signal controller 8 is specifically used for processing digital signals and is suitable for applications that require high-speed signal processing. The digital signal controller 8 includes the Texas Instruments (TI) C2000 series. Specifically, the specific model of the controller 8 can be selected according to needs, and this application does not limit this.

[0074] In some embodiments, the power source 7 is an independent lithium battery pack, the drive motor 41 is a stepper motor or a servo motor, and the controller 8 is a stepper driver or a servo driver, which can control the precise rotation angle of the drive motor 41 according to the set instructions, and then drive the gear 31 to rotate through the rack 32. The gear 31 drives the rotating shaft 21 to rotate at an angle. The structure is simple and easy to operate. Since the power source 7 and the controller 8 can independently control the above-mentioned linear drive assembly 4 to deflect the display body 2 towards the driver and passenger seats, without changing the original control circuit and control unit of the vehicle, the display screen assembly 10 can be quickly installed on the center console of an ordinary vehicle, which has the advantages of simple and fast installation.

[0075] Referring to Figure 4 and Figure 5 , in some embodiments, the display body 2 includes a screen body 22 and a support platform 23. The support platform 23 protrudes from the back surface of the screen body 22. The support platform 23 abuts against the base 1. The rotating shaft 21 is connected to the side of the support platform 23 facing the base 1. Among them, along the direction from the display body 2 to the base 1, the cross-section of the support platform 23 is arranged in an increasing manner. In this way, the contact area between the support platform 23 and the base 1 can be increased, thereby improving the overall stability of the display body 2. By increasing the cross-sectional area of the bottom of the support platform 23, the weight of the display body 2 can be better dispersed, local pressure can be reduced, and the risk of deformation of the base 1 or the support platform 23 can be lowered. The larger contact area between the support platform 23 and the base 1 can improve the stability during rotation and reduce shaking. The larger cross-sectional area helps to improve the torsional resistance of the support platform 23, making the display body 2 more stable during rotation. A more stable support platform 23 can reduce the risk of the display body 2 tipping over and improve the use safety.

[0076] Referring to Figure 4 and Figure 5, in some embodiments, a display socket 221 is provided on the back of the screen main body 22, and the support platform 23 is further provided with a through hole 231. The through hole 231 penetrates the support platform 23 along the axial direction of the rotation shaft 21. The rotation shaft 21 is hollow, and one end of the rotation shaft 21 communicates with the through hole 231, and the other end of the rotation shaft 21 communicates with the installation space 11. The base 1 is further provided with an interface 15 and a data cable 9. The interface 15 has a first connection terminal and a second connection terminal. The first connection terminal is located inside the installation space 11, and the second connection terminal is located outside the installation space 11. One end of the data cable 9 is electrically connected to the display socket 221, and the other end of the data cable 9 passes through the rotation shaft 21 and the through hole 231 and is electrically connected to the first connection terminal. The second connection terminal is used to connect a display signal input device. In this way, through the hollow design of the rotation shaft 21 and the through hole 231 on the support platform 23, the data cable 9 can flexibly pass through these spaces and be connected to the interface 15 of the base 1. This method enables the screen main body 22 to stably receive and transmit display signals while maintaining the rotation function. Since the data cable 9 passes through the inside of the rotation shaft 21 and the support platform 23, the external wiring is well hidden, making the whole device look cleaner and more beautiful. The design of the data cable 9 passing through the rotation shaft 21 and the support platform 23 also helps to protect the data cable 9 from damage by the external environment. If it is necessary to replace or repair the data cable 9, this design makes the operation more convenient. The user only needs to disassemble a part of the base 1 or the support platform 23 to easily access the data cable 9 for replacement or repair. Since the second connection terminal of the interface 15 is located outside the installation space 11, the user can conveniently connect a display signal input device, such as a computer, a TV box or other display signal sources, thereby enhancing the overall functionality of the display screen assembly 10.

[0077] Referring to Figure 5 , in one embodiment, the bottom end of the hollow rotation shaft 21 is provided with an arc chamfer. In this way, the arc chamfer can reduce the stress concentration at the bottom end of the rotation shaft 21, especially at the part where the rotation shaft 21 is connected to the data cable 9. This helps to reduce the tensile or torsional stress on the data cable 9 during rotation. The arc chamfer can improve the contact surface between the bottom end of the rotation shaft 21 and the data cable 9, making the data cable 9 more smooth during rotation and reducing friction. The arc chamfer can reduce the wear between the bottom end of the rotation shaft 21 and the data cable 9 and extend the service life of the data cable 9. By reducing stress concentration, the arc chamfer helps to reduce the risk of the data cable 9 breaking when the display main body 2 rotates.

[0078] Referring to Figure 2 and Figure 5, in some embodiments, the display screen assembly 10 further includes a bearing 101. The bearing 101 is installed on the base 1 and sleeved on the rotating shaft 21. In this way, the bearing 101 can significantly reduce the friction between the rotating shaft 21 and the base 1, making the rotation of the display body 2 smoother. The use of the bearing 101 can improve the accuracy of the display body 2 during rotation and reduce shaking or wobbling phenomena. By reducing friction, the bearing 101 can extend the service life of the rotating shaft 21 and the base 1 and reduce maintenance costs. The use of the bearing 101 can reduce the noise generated during rotation and improve the user experience. The bearing 101 can provide better support for the rotating shaft 21 and improve the structural stability of the entire display screen assembly 10. The use of the bearing 101 can simplify the installation and disassembly process of the rotating shaft 21, facilitating maintenance and replacement. Using the bearing 101 can increase the load-bearing capacity of the rotating shaft 21, making the display body 2 more stable during rotation. Due to the reduced friction, the display body 2 can rotate at a higher speed, improving the response speed.

[0079] The following describes the specific operations of the display screen assembly 10:

[0080] When a person in the driver's seat presses the forward offset switch 61, the forward offset switch 61 sends a forward rotation command to the controller 8. Then, the controller 8 controls the driving motor 41 to rotate forward. Finally, the screw rod 42 drives the nut 43 to move to the right. Since the nut 43 is connected to the rack 32, the nut 43 drives the rack 32 to move to the right. The rack 32 drives the gear 31 to rotate clockwise, driving the rotating shaft 21 and the display body 2 to deflect towards the driver's seat. When a person in the passenger seat presses the reverse offset switch 62, the reverse offset switch 62 sends a reverse rotation command to the controller 8. Then, the controller 8 controls the driving motor 41 to rotate in reverse. Finally, the screw rod 42 drives the nut 43 to move to the left. Since the nut 43 is connected to the rack 32, the nut 43 drives the rack 32 to move to the left. The rack 32 drives the gear 31 to rotate counterclockwise, driving the rotating shaft 21 and the display body 2 to deflect towards the passenger seat.
