Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a screen adjustment device and a vehicle thereof. Background Technology

[0002] In today's rapidly developing automotive industry, in-vehicle product technology is constantly innovating to meet consumers' growing demands for intelligent and convenient vehicles. Among these technologies, the screen, as a crucial information interaction interface within the vehicle, receives significant attention for its performance and user experience.

[0003] The screen is typically mounted on the vehicle's center console, serving multiple key functions such as displaying navigation information, multimedia content, air conditioning status, and vehicle settings. It is an important window for the driver to obtain and interact with vehicle-related information. To ensure the screen can be stably mounted in the driver's cabin and to meet the driver's needs for screen position and angle in different usage scenarios, a bracket structure has been developed.

[0004] Currently, some car models on the market use screen bracket structures with multiple functions, such as rotation and retraction. The rotation function allows drivers to flexibly adjust the orientation of the center console screen according to their seating position and line of sight, ensuring a clear view of the information on the screen; while the retraction function allows the center console screen to be adjusted in the forward and backward direction, further improving convenience and comfort.

[0005] In related technologies, movable support structures utilize motors and gears for drive, with some also incorporating telescopic mechanisms. While this design allows for screen position and angle adjustments, it makes the entire support structure extremely complex, increasing assembly difficulty during production. Furthermore, the complex structural design includes multiple mechanical components such as motors, gears, and telescopic mechanisms, causing the support structure to occupy a significant amount of space within the driver's cabin. Given the limited interior space of a car, an excessively large support structure can compress the installation space for other components and may even affect the aesthetics and rationality of the overall interior layout, leading to a poor user experience.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] In some exemplary embodiments, such as Figures 1-5 As shown, a screen adjustment device 1 is provided. The screen can be a vehicle central control screen or an electronic device screen. The screen adjustment device 1 can be installed on the vehicle's central control console to facilitate flexible control of the screen 2, enabling free adjustment of the screen 2's angle and improving the user experience. The screen adjustment device 1 includes a support frame 11, a drive unit 12, and a rotating unit 13.

[0045] In this embodiment, as Figures 1-5 As shown, the support frame 11 serves as the basic support structure for the entire adjustment device and can be fixedly connected to the vehicle's center console. For example, the support frame 11 is provided with a first connecting lug 111, on which a threaded hole 1111 matching a screw or bolt is pre-machined. During installation, the screw or bolt is rotated through the threaded hole 1111 on the first connecting lug 111 and screwed into the pre-set mounting hole on the vehicle's center console. In this way, the support frame 11 is tightly fixed to the vehicle's center console, thereby effectively improving the stability of the entire device and ensuring that the adjustment device will not be affected by shaking during vehicle operation.

[0046] The support frame 11 is provided with a limiting shaft 112, which is a cylindrical structure. The cylindrical limiting shaft 112 has the characteristics of smooth surface and high dimensional accuracy, which facilitates the subsequent installation of the rotating part 13, and can provide stable support and precise guidance for the rotation of the rotating part 13.

[0047] In this embodiment, as Figures 1-5 As shown, the drive unit 12 is fixedly connected to the support frame 11 to improve the stability of the drive unit 12. During installation, the drive unit 12 is first placed in the pre-designed installation position on the support frame 11, and then the drive unit 12 is firmly fixed to the support frame 11 by welding, snap-fit ​​connection, or using special fasteners (such as fixing screws). This fixed connection method can effectively improve the stability of the drive unit 12, ensuring that the drive unit 12 will not shake or shift during operation, thereby ensuring that it can output power stably.

[0048] In this embodiment, as Figures 1-5 As shown, the rotating part 13 plays a role in transmission and rotation in the entire adjustment device. On one hand, the rotating part 13 is connected to the screen 2, ensuring that it can drive the screen 2 to rotate together to meet different viewing angle requirements. The rotating part 13 is provided with a connection structure 134 for connecting to the screen 2. This connection structure 134 allows for detachable connection to the screen 2, improving the flexibility of the entire adjustment device. This connection method is not only convenient for installation and disassembly but also ensures the firmness of the connection between the screen 2 and the rotating part 13, effectively preventing loosening or detachment during use. On the other hand, the rotating part 13 is connected to the drive part 12, allowing the power output from the drive part 12 to be transmitted to the rotating part 13.

[0049] Meanwhile, the rotating part 13 is movably disposed on the limiting shaft 112. For example, the rotating part 13 is provided with a limiting hole 1321 that matches the limiting shaft 112. When the limiting shaft 112 is inserted into the limiting hole 1321 of the rotating part 13, the rotating part 13 can rotate around the limiting shaft 112.

[0050] The drive unit 12 is configured to drive the rotating unit 13 to rotate around the limiting shaft 112, and can be adjusted according to the user's needs. The drive unit 12 is, for example, an electric drive unit with a motor.

[0051] On the one hand, users can manually control and adjust the angle, which is simple and direct and suitable for some scenarios where the angle adjustment requirements are not high, satisfying the user's intuitive feeling. On the other hand, the drive unit 12 can provide auxiliary drive to improve the smoothness of adjustment.

[0052] On the other hand, the drive unit 12 can provide a powerful and stable power to the rotating unit 13 to achieve flexible and precise adjustment of the screen 2 angle. It can be adjusted to any position and automatically deflects the angle to optimize the visual experience.

[0053] Reference Figure 6 As shown, the adjustment angle α of screen 2 can be flexibly set according to the user's needs. For example, when screen 2 is parallel to the vehicle's central console, it is set to an initial angle of 0°. With the limit shaft 112 as the central axis, it can rotate 15° counterclockwise or 15° clockwise relative to the initial angle.

[0054] It is understood that the aforementioned 15° is merely illustrative and does not constitute a limitation on this application. The 15° value is derived from ergonomic design experience and can meet the visual needs of most users during normal driving. In fact, screen 2 can automatically tilt according to user needs, with a maximum angle of 20° or 30°, etc. By continuously optimizing and adjusting the angle, a more comfortable visual experience can be provided to the user.

[0055] In actual use, users can control the working state of the drive unit 12 by operating the preset control buttons on the vehicle or by issuing commands through the in-vehicle system. When the drive unit 12 is started, the drive rotating unit 13 rotates around the limiting shaft 112. The rotating unit 13 drives the screen 2 connected to it to rotate together, thereby realizing flexible adjustment of the screen 2 angle. This meets the needs of different users for the screen 2 angle in different usage scenarios. Whether it is viewing information while driving or operating entertainment while parked and resting, it can provide users with the best visual angle, greatly improving the user experience.

[0056] The screen adjustment device 1 in this embodiment has a simple overall structure, effectively reducing the complexity of parts, facilitating the assembly process, and saving internal layout space. At the same time, the device has high reliability, with tight cooperation between components, ensuring stable operation over a long period; it is highly practical, effectively meeting the actual needs of users; and it is full of technological sophistication, bringing users a brand-new user experience.

[0057] In some exemplary embodiments, such as Figures 1-5 As shown, the rotating part 13 includes a spherical rotating body 132, which is made of a high-strength, wear-resistant alloy material and has a finely polished surface to reduce friction during rotation, providing flexible and stable support for the angle adjustment of the screen 2. The support frame 11 is provided with a receiving space 113 that mates with the spherical rotating body 132, so that the spherical rotating body 132 can be rotatably disposed within the receiving space 113.

[0058] The diameter of the spherical rotator 132 is rationally designed according to the overall size of the device and the usage requirements to ensure that it can rotate smoothly within the accommodating space 113 of the support frame 11. The design of the spherical rotator 132 allows the rotating part 13 to rotate flexibly in multiple directions, thereby realizing multi-angle adjustment of the screen 2.

[0059] The accommodating space 113 can be a spherical groove adapted to the spherical rotating body 132, with its size slightly larger than the diameter of the spherical rotating body 132, so that the spherical rotating body 132 can be rotatably disposed within the accommodating space 113. The design of the spherical rotating body 132 allows the rotating part 13 to rotate flexibly in multiple directions, and the user can adjust the screen 2 to any suitable angle according to actual needs, thereby realizing multi-angle adjustment of the screen 2. At the same time, the accommodating space 113 can also act as a limiter, constraining the spherical rotating body 132 in multiple directions to prevent it from deviating too much during rotation, making the rotation more stable.

[0060] The inner wall of the accommodating space 113 is provided with a limiting shaft 112. There can be one or two limiting shafts 112, and there can also be one or two limiting holes 1321 that cooperate with the limiting shafts 112.

[0061] In some examples, such as Figure 2 , Figure 7 As shown, the limiting hole 1321 includes a first sub-hole 13211 and a second sub-hole 13212 that are arranged opposite to each other. The first sub-hole 13211 and the second sub-hole 13212 are not connected and are located on opposite sides of the spherical rotating body 132, respectively.

[0062] A limiting shaft 112 is provided in both the first sub-hole 13211 and the second sub-hole 13212, and the two limiting shafts 112 are coaxially opposite each other. The two coaxially opposite limiting shafts 112 can provide stable and precise support and guidance for the rotating part 13 from both sides, ensuring that the rotating part 13 can rotate smoothly and steadily around the limiting shafts 112, avoiding deviation or jamming during rotation, thereby ensuring the accuracy and reliability of screen angle adjustment.

[0063] In other examples, such as Figure 2 , Figure 7 As shown, the limiting hole 1321 includes a through hole 13213 penetrating the spherical rotating body 132. The diameter of the through hole 13213 is adapted to the diameter of the limiting shaft 112, and the limiting shaft 112 is disposed within the through hole 13213. The function of the limiting hole 1321 is to accommodate the limiting shaft 112. Through the cooperation of the two, it ensures that the spherical rotating body 132 can rotate freely around the limiting shaft 112, allowing the screen 2 to be angled according to user needs; it also limits the range of movement of the spherical rotating body 132, preventing it from shifting or falling off during rotation, and ensuring the stability and accuracy of rotation.

[0064] In practical use, users can drive the rotating part 13 to rotate manually or with the aid of electric control. When the spherical rotating body 132 of the rotating part 13 rotates around the limiting axis 112 within the accommodating space 113, it will drive the screen 2 connected to it to rotate together, thereby realizing flexible adjustment of the screen 2 angle. Whether using a double limiting axis and double sub-hole combination or a single limiting axis and through hole combination, the stability and accuracy of the screen 2 during the adjustment process can be guaranteed, meeting the user's needs for screen viewing angle in different scenarios.

[0065] In some exemplary embodiments, such as Figures 1-5 As shown, the support frame 11 includes a support base 114 and a support cover 115. The split structure facilitates processing and manufacturing, improves production efficiency and product quality, and also facilitates the installation of the rotating part 13.

[0066] The support base 114 has a first groove 1141, and the support cover 115 has a second groove 1151. The support cover 115 and the support base 114 are disposed opposite to each other on both sides of the rotating part 13. When the two are combined, the first groove 1141 and the second groove 1151 are connected to form an accommodating space 113, which can more comprehensively accommodate the rotating part 13 and provide better protection and support for the rotating part 13.

[0067] The support base 114 is positioned below the spherical rotating body 132, supporting it, bearing its weight, and providing basic support. The support cover 115 is positioned above the spherical rotating body 132, covering its upper side and creating a wrapping effect. Together, these two components constrain the spherical rotating body 132 from both above and below, limiting its vertical movement and ensuring stable horizontal rotation. This constraint method ensures that the spherical rotating body 132 does not experience vertical bouncing or other instability during rotation, further improving the stability and reliability of the entire rotating structure.

[0068] The accommodating space 113 is a channel structure that runs through the support frame 11 in the horizontal direction. It can provide a rotatable space for the spherical rotating body 132 in the horizontal direction, and can also properly wrap and accommodate the spherical rotating body 132. It constrains the spherical rotating body 132 from multiple directions, provides more reliable protection for the spherical rotating body 132, prevents it from being affected by external collisions, and provides more stable support to ensure the stability of the spherical rotating body 132 during rotation.

[0069] A channel structure is used as the accommodating space 113, and the inner diameter of the channel needs to be designed according to the dimensions of the spherical rotating body 132. The dimensions of the channel structure must ensure that the spherical rotating body 132 will not fall out of the channel during rotation, and that the spherical rotating body 132 can rotate stably around the limiting axis 112 within the channel. If the size is too large, the spherical rotating body 132 will produce large wobbling when rotating within the channel, affecting the stability and accuracy of rotation; if the size is too small, the spherical rotating body 132 may experience excessive friction with the inner wall of the channel, or even fail to rotate normally. The inner wall surface of the channel structure should be smooth to reduce the friction between the spherical rotating body 132 and the inner wall during rotation, thereby improving the smoothness of rotation. At the same time, in order to improve the smoothness of rotation, a special surface treatment process can be used to make the inner wall surface of the channel even smoother.

[0070] The placement of the first limiting shaft 112 is flexible. It can be located within the first groove 1141, the second groove 1151, or both. The spherical rotating body 132 is located within both the first and second grooves 1141 and rotatably connected to the limiting shaft 112. When one limiting shaft 112 is placed in each of the first and second grooves 1151, the two limiting shafts 112 are coaxially aligned, providing support and guidance from both the upper and lower sides of the spherical rotating body 132 simultaneously. This ensures uniform force distribution on the spherical rotating body 132 during rotation, further enhancing the stability and accuracy of the rotating part 13's rotation.

[0071] During the rotation of the spherical rotating body 132, the two coaxial limiting shafts 112 ensure that the spherical rotating body 132 is subjected to uniform force. If the force is uneven, the spherical rotating body 132 may experience problems such as uneven rotation, jamming, or even deviation. The coaxial limiting shafts 112 effectively avoid these situations, greatly enhancing the stability and accuracy of the rotation of the spherical rotating body 132. This is crucial for applications requiring precise screen angle adjustment, ensuring high quality and reliability of screen angle adjustment and providing users with a smooth and accurate operating experience.

[0072] In this embodiment, as Figures 1-5 As shown, the support base 114 is L-shaped, and a receiving groove 1142 is provided on the horizontally positioned support base 114. The receiving groove 1142 is configured to receive the driving part 12. The shape and size of the receiving groove 1142 can be adapted to the driving part 12. For example, the driving part 12 can be embedded in the receiving groove 1142, ensuring that the driving part 121 and each contact surface of the receiving groove 1142 are tightly fitted without any obvious gaps, thereby forming a tight and stable connection. For example, fixing the driving part 12 in the receiving groove 1142 by adhesive bonding can further improve the reliability of the connection. For example, the support body 114 is provided with a stepped groove 1145 that communicates with the receiving groove 1142, and the drive part 12 is provided with a second connecting lug 1211. The second connecting lug 1211 can be embedded in the stepped groove 1145. Both the second connecting lug 1211 and the stepped groove 1145 are provided with corresponding threaded holes. The second connecting lug 1211 is fixed to the support body 114 by bolts or screws, thereby improving stability and reducing the problem of loosening of the connection due to vibration or external force.

[0073] The support base 114 adopts an L-shape, realizing the utilization of multi-dimensional space and facilitating the miniaturization design of the screen adjustment device 1. At the same time, the drive unit 12 is embedded in the receiving groove 1142, making the overall structure more compact and further optimizing the overall spatial layout.

[0074] In this embodiment, as Figures 1-5 As shown, the support body 114 includes a first support 1143 and a second support 1144. The first support 1143 and the second support 1144 are connected, and can be fixedly connected or integrally formed, to jointly undertake the support and transmission functions of the various components of the device.

[0075] The first support 1143 is connected to the drive unit 12. A receiving groove 1142 is provided on the first support 1143, and the drive unit 12 can be fixed in the receiving groove 1142 by embedding or bonding. The second support 1144 is connected to the rotating unit 13. A receiving space 113 is provided on the second support 1144. The receiving space 113 is used to accommodate part of the structure of the rotating unit 13 or to provide space for the movement of the rotating unit 13, so as to ensure that the rotating unit 13 can rotate smoothly, thereby realizing the adjustment of the screen angle.

[0076] The first support 1143 and the second support 1144 have a preset angle between them, which is 60°-120°. For example, when the preset angle is set to 90°, the first support 1143 and the second support 1144 form an L-shape, which can more effectively disperse the various forces generated by the device during operation and improve the stability and load-bearing capacity of the entire support 114.

[0077] In practical use, when the drive unit 12 drives the rotating unit 13 to rotate, a certain amount of action and reaction forces are generated. The L-shaped structure can better distribute and balance these forces, avoiding damage or deformation of the device due to excessive local stress. Furthermore, it makes more rational use of space, resulting in a more compact overall structure that facilitates installation and layout.

[0078] In some exemplary embodiments, such as Figures 1-5 As shown, the rotating part 13 includes a first rotating support 131, a spherical rotating body 132 and a second rotating support 133 connected in sequence, providing flexible and stable support for the angle adjustment of the screen 2.

[0079] The first rotating support 131 is connected to the connecting structure 134. The connection method must ensure a firm and stable connection, accurately transmitting the movement of the rotating part 13 to the screen 2 via the connecting structure 134. In practical applications, the connecting structure 134 and the first rotating support 131 can be an integrally formed structure to improve the reliability of the connection. The connecting structure 134 can be connected to the screen 2 using bolts. Threaded holes are provided at corresponding positions on the connecting structure 134 and the screen 2, and the two are tightly fixed together using matching bolts and nuts. This connection method is not only convenient for installation and disassembly but also can withstand various forces generated by the screen 2 during angle adjustment, ensuring the reliability of the connection.

[0080] A spherical rotating body 132 is rotatably mounted on a limiting shaft 112. The design of the spherical rotating body 132 allows the rotating part 13 to rotate flexibly in multiple directions, thereby enabling multi-angle adjustment of the screen 2. To ensure a stable fit between the spherical rotating body 132 and the limiting shaft 112, a limiting hole 1321 is provided on the spherical rotating body 132. The shape and size of this limiting hole 1321 are adapted to the shape of the limiting shaft 112. The function of the limiting hole 1321 is to accommodate the limiting shaft 112. Through their cooperation, the spherical rotating body 132 can rotate freely around the limiting shaft 112, while its range of movement is limited, preventing it from shifting or falling off during rotation and ensuring the stability and accuracy of the rotation.

[0081] The second rotating support 133 is connected to the drive unit 12 to transmit power to the second rotating support 133. The second rotating support 133 is, for example, inverted L shape, opposite to the L shape of the support frame 11, providing more stable support and enhancing the connection strength between the rotating part 13 and the support frame 11.

[0082] In some exemplary embodiments, such as Figures 1-5 As shown, the drive unit 12 includes a drive body 121, a drive shaft 122, a connecting body 123, and a connecting shaft 124. The drive body 121 is a drive motor, which is the power source of the entire drive unit 12, responsible for converting electrical energy into mechanical energy to provide power support for subsequent transmission and movement. The drive shaft 122 is a motor shaft, directly connected to the drive body 121, and can rotate around its own axis under the action of the drive body 121.

[0083] The drive body 121 can be disposed within the receiving groove 1142 of the support frame 11 and fixedly connected thereto to ensure that it will not be displaced due to vibration or external force during operation, thus ensuring the stability of the entire device and improving its compactness. The drive body 121 and the drive shaft 122 are tightly connected by a suitable connection method, such as a key connection or interference fit, to ensure that the power generated by the drive body 121 can be efficiently and accurately transmitted to the drive shaft 122.

[0084] The connector 123 is a plate-like structure with a large connection area and good strength, capable of withstanding large forces. The connector 123 is sleeved on the drive shaft 122 and fixedly connected to the drive shaft 122. It can be connected by welding, bolts, or pins to ensure that the connector 123 can be firmly fixed to the drive shaft 122 and move synchronously with the rotation of the drive shaft 122.

[0085] One end of the connecting shaft 124 is connected to the connecting body 123 and is located on the side away from the driving shaft 122. The connecting shaft 124 and the connecting body 123 can also be fixedly connected, such as by welding, bolting, or pinning, so that the connecting shaft 124 can move synchronously with the connecting body 123. That is, when the connecting body 123 rotates under the drive of the driving shaft 122, the connecting shaft 124 will also make a circular motion.

[0086] The other end of the connecting shaft 124 is connected to the second rotating support 133 of the rotating part 13. For example, the second rotating support 133 of the rotating part 13 is provided with a shaft hole 1331, and the radial dimension of the shaft hole 1331 is larger than the radial dimension of the connecting shaft 124, so that the other end of the connecting shaft 124 can be movably inserted into the shaft hole 1331. When the connecting shaft 124 moves, it can push against the inner wall of the shaft hole 1331, thereby driving the second rotating support 133 to move.

[0087] In actual operation, when the drive unit 121 is activated, the power it generates is transmitted to the connecting body 123 through the drive shaft 122, causing the connecting body 123 to rotate around the axis of the drive shaft 122. During this movement, the connecting body 123 pushes against the inner wall of the shaft hole 1331 through the connecting shaft 124, further transmitting the power to the second rotating support 133. The second rotating support 133 transmits force to the spherical rotating body 132. Because the spherical rotating body 132 is restricted by the limiting shaft 112, it can only rotate around the limiting shaft 112 within a specific range. Therefore, the connecting shaft 124 drives the rotating part 13 to rotate around the limiting shaft 112. As the rotating part 13 moves, the screen 2 connected to it also changes angle, thereby achieving the adjustment of the screen 2 angle.

[0088] The electric drive method is more flexible and can respond quickly to user needs, enabling instant adjustment of the screen angle. At the same time, the electric drive method is highly efficient and energy-saving, completing the angle adjustment task in a short time and reducing energy consumption. Moreover, by precisely controlling the speed and direction of the drive motor, the screen angle can be precisely adjusted, meeting users' needs for quick and accurate adjustment of the screen angle in different scenarios, greatly improving the user experience.

[0089] In some exemplary embodiments, such as Figures 1-5 As shown, the connection structure 134 includes a connection plate 1341 and a fastener 1342. The connection plate 1341 is detachably connected to the screen 2 via the fastener 1342.

[0090] For example, the connecting plate 1341 may be in a flat state, and it can be fixedly connected to the first rotating support 131 or integrally formed to improve the reliability of the connection. The connecting plate 1341 has a through screw hole, and the back of the screen 2 also has a connecting screw hole. The fastener 1342 is, for example, a screw, one end of which is screwed through the through screw hole and connected to the connecting screw hole. This method has a simple structure, is convenient to install and disassemble, and is suitable for scenarios where ease of installation is crucial.

[0091] Alternatively, the connection structure 134 includes a connecting plate 1341, a fastener 1342, and a housing 1343. The housing 1343 has a connecting screw hole, and the connecting plate 1341 has a through screw hole. The fastener 1342 is, for example, a screw, one end of which is screwed through the through screw hole and connected to the connecting screw hole. The housing 1343 has a groove structure, in which the screen 2 can be detachably placed. The groove structure of the housing 1343 not only provides some protection for the screen 2, preventing it from being damaged by impacts during installation and use, but also makes the installation of the screen 2 more stable, making it particularly suitable for applications requiring high stability and protection for the screen 2.

[0092] like Figures 1-5 As shown, this disclosure also provides a vehicle, including a vehicle body (not shown in the figure), a screen 2, and two adjustment devices 1 as described in any of the above embodiments.

[0093] The screen 2 is connected to the rotating part 13 of the adjustment device 1, which ensures that the screen 2 can be adjusted in angle as the rotating part 13 moves, while ensuring the stability and reliability of the connection and being able to withstand the vibration and impact generated during vehicle operation.

[0094] The support frame 11 of the adjustment device 1 is connected to the central control console of the vehicle body, providing a stable support base for the entire adjustment device 1 so that it can work normally.

[0095] The screen adjustment device 1 has a wide range of adjustment angles. The spherical rotating body 132 in its rotating part 13 can rotate in multiple directions around the limiting axis 112. Combined with the synergistic effect of the first rotating support 131 and the second rotating support 133, the screen 2 can be adjusted within a large angle range. For example, adjustment angles of at least 15° and above. In the horizontal direction, the screen 2 can be tilted to the left and right by a certain angle to meet the viewing needs of users in different seats. This wide range of adjustment angles ensures that users can obtain a clear and comfortable visual experience in different driving scenarios and usage postures.

[0096] The adjustment device 1 can automatically adjust the viewing angle according to user needs. The vehicle is equipped with an intelligent control system that can acquire user position information, line of sight, and other data in real time through sensors. For example, when the user is sitting in the driver's seat, the sensors can detect the user's head position and line of sight angle and transmit this data to the control system. The control system analyzes and processes the data according to a preset algorithm, and then controls the drive unit 12 in the adjustment device 1 to work, driving the rotating unit 13 to automatically adjust the screen 2 to the optimal viewing angle. This automatic adjustment function greatly improves the convenience and comfort of the user, eliminating the need for the user to frequently adjust the screen angle manually.

[0097] The screen adjustment device 1 has a simple overall structure, reducing the complexity of its components. It mainly includes a support frame 11, a rotating part 13, and a drive part 12. Compared to the complex adjustment mechanisms in related technologies, the adjustment device 1 of this disclosure has fewer components. This not only facilitates the assembly process, reduces assembly time and difficulty, and improves production efficiency, but also lowers the procurement and manufacturing costs of components. Simultaneously, the simple structure reduces the space occupied inside the device, saving space within the vehicle and providing more space for the installation and arrangement of other vehicle components.

[0098] The adjustment device 1 supports manual control. Users can directly rotate the screen 2 to adjust its angle. During manual control, the drive motor of the drive unit 12 provides auxiliary drive, offering power support for the rotation of the rotating unit 13, making manual adjustment easier and less strenuous for the user. Simultaneously, the auxiliary drive of the drive motor ensures the smoothness of the adjustment process, preventing any jerking or sudden acceleration.

[0099] The adjustment device 1 also supports electric control. Users can send electric control commands via the vehicle's central control system or a mobile app. Upon receiving the command, the control system will precisely control the motor to drive the rotating part 13, which in turn rotates the screen 2 to the designated position. Furthermore, the adjustment device 1 can stop at any position to meet the user's personalized needs for different angles. For example, the user can position the screen 2 at a specific tilt angle to achieve the best visual effect.

[0100] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0101] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
