[0016] According to a third aspect provided by the present application, a vehicle is provided, which may include a dashboard and the above-mentioned rotating screen, and the mounting bracket is connected to the dashboard.

[0017] Beneficial effects of the utility model:

[0018] (1) The present application can drive the abutment portion to rotate by the driving member, and the abutment portion drives the rotating member to rotate until the abutment portion abuts against the limiting member, so that the abutment portion no longer rotates, and the rotating member stops rotating along with the abutment portion, and reaches the maximum rotation angle that the rotating member can achieve. Therefore, when the user removes the limiting member from the original installation portion and connects it to the installation portion at another position, the abutment position between the abutment portion and the limiting member can be changed, and the maximum rotation angle that the rotating member can achieve can be adjusted.

[0019] (2) The present application sets the limiting member as a ring-shaped structure surrounding the output shaft, which can improve the structural compactness of the angle adjustment device while ensuring the connection strength between the limiting member and the housing. In addition, when the abutting portion rotates in the rotation space in a clockwise direction, the abutting portion can stably abut against the first limiting ring; when the abutting portion rotates in the rotation space in a counterclockwise direction, the abutting portion can stably abut against the second limiting ring. That is, the present application can adjust the size of the above-mentioned rotation space and the rotation range of the output shaft by changing the connection position of the first limiting ring and the second limiting ring on the housing.

[0020] (3) On the one hand, after the multiple limit blocks on the first limit ring or the second limit ring are correspondingly connected to the multiple connecting slots on the shell, the connection strength between the first limit ring and the second limit ring and the shell can be improved, thereby preventing the first limit ring and the second limit ring from being separated from the shell after being subjected to the force of the abutment part; on the other hand, during each adjustment process, the new position of the first limit ring or the second limit ring on the shell is offset from the original position by one connecting slot, thereby forming a rotation space of different size from the original one, and the smaller the spacing between the multiple limit blocks and their corresponding connecting slots, the higher the adjustment accuracy of the angle adjustment device.

[0021] (4) The torque of the motor can be transmitted to the sector gear through the gear assembly, and the sector gear then stably transmits the torque to the output shaft.

[0022] (5) The present application allows the motor to be placed horizontally and the direction of power transmission to be changed by meshing the worm and the gear assembly, thereby making the overall structure of the angle adjustment device relatively light, thin, and beautiful while satisfying the torque output direction. In addition, because the friction angle of the worm is smaller than the lead angle of the worm, the angle adjustment device can be reverse-driven, that is, the user can directly manually rotate the output shaft, which drives the sector gear, gear assembly, worm, and motor shaft to rotate in the opposite direction.

[0023] (6) A larger transmission ratio can be obtained through two double gears, so that the gear assembly can reduce the high-speed motion of the motor to a reasonable low-speed range through the gear assembly while occupying a smaller installation space, and transmit it to the output shaft, so that the mounting tray connected to the output shaft and the screen body on the mounting tray can rotate smoothly.

[0024] (7) The third double gear can further increase the transmission ratio of the gear assembly, allowing the sector gear and the output shaft to achieve a lower rotational speed. In this way, when the weight and inertia of the screen body on the mounting tray are large, the output shaft can slowly and smoothly adjust its rotation angle, preventing the screen body from sliding off the mounting tray, thereby ensuring the safety of the angle adjustment process.

[0025] (8) The present application can calibrate the position of the output shaft through the first limiting ring, the second limiting ring and the angle detection component, so that the output shaft can be accurately rotated to the middle position of the rotation space formed by the first limiting ring and the second limiting ring.

[0037] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0039] With the development of vehicle technology and the Internet of Vehicles, the functions of the vehicle's central control screen are no longer limited to traditional multimedia functions. It can also provide functions such as route planning, panoramic imaging, video playback, and vehicle control, providing users with a more comfortable driving experience and entertainment experience, and meeting users' diverse needs.

[0040] In related technologies, an angle adjustment device is typically installed between the central control screen and the instrument panel to facilitate driver and passenger adjustments to a preferred viewing angle. Patent number CN213768431U, entitled "Automotive Central Control Rotating Screen Actuator," utilizes a first limiting structure and a second limiting structure to adjust the reciprocating rotation of the output gear. The output gear's notch cooperates with a limiting pin to limit the output gear's rotation angle, allowing users to rotate the screen left or right as desired. The aforementioned automotive central control rotating screen actuator is compact, does not require significant space, and is easy to deploy.

[0041] However, since the position of the limit pin is fixed, the limit angle of the output gear is also fixed, and the maximum rotation angle of the rotating screen connected to the output gear cannot be flexibly adjusted according to the specific use requirements of actual application scenarios.

[0042] In order to solve the above technical problems, the present application provides an angle adjustment device, the maximum rotation angle of which can be flexibly adjusted according to the specific usage requirements of actual application scenarios, so that the present application can be better applied to rotating screens or other devices that require angle adjustment. The following will focus on the application of the present application in rotating screens, which cannot be considered as a special limitation on the present application.

[0043] Figure 1 The diagram shows the structure of the rotating screen provided by the embodiment of the present application. Figure 1 In some embodiments of the present application, the rotating screen 1 may include a screen body, a mounting tray 10, an angle adjustment device 20, and a mounting bracket 30. The screen body may display different types of information depending on the specific application of the rotating screen 1. For example, if the rotating screen 1 is used in a vehicle, the screen body may display driving assistance information such as navigation routes, panoramic images, vehicle speed, and tire pressure. If the rotating screen 1 is used in a restaurant, milk tea shop, or cake shop, the screen body may display product information such as the appearance, introduction, and price of dishes, drinks, and pastries. If the rotating screen 1 is used in a waiting room, the screen body may display the estimated arrival time of the day's trains, thereby facilitating different users to obtain the required relevant information through the screen body.

[0044] Continue reading Figure 1 In some embodiments of the present application, the mounting tray 10 of the rotating screen 1 is arranged below the screen body for stably supporting the screen body, and the size of the mounting tray 10 can be set according to the size of the screen body.

[0045] Continue reading Figure 1The rotating member 22 in the angle adjustment device 20 is connected to the mounting tray 10. The rotating member 22 can output torque within a certain angle range to drive the mounting tray 10 to rotate within a certain angle range to adjust the angle of the screen body toward the user.

[0046] Continue reading Figure 1 The mounting bracket 30 is connected to the angle adjustment device 20 and is used to connect the part to be installed. The part to be installed can be a dashboard of a vehicle, a wall of a store, or a display cabinet. The specific structure of the mounting bracket 30 can be appropriately changed according to the different parts to be installed, as long as the angle adjustment device 20 can be stably connected to the part to be installed.

[0047] The specific structure of the angle adjustment device 20 in this application is described in detail below. Figure 2 The diagram shows the structure of the angle adjustment device 20 provided in the embodiment of the present application. Figure 2 In some embodiments of the present application, the angle adjustment device 20 may include a shell 21, a rotating member 22, a driving member 23 and a limiting member 24. A accommodating cavity is formed in the shell 21, the rotating member 22 is passed through the shell 21, and an abutting portion 25 is provided on the rotating member 22; the driving member 23 is provided in the accommodating cavity, and is used to drive the abutting portion 25 to rotate. The limiting member 24 is connected to the shell 21, and the limiting member 24 can abut against the abutting portion 25. Among them, a plurality of mounting portions 210 are provided on the shell 21, and the plurality of mounting portions 210 are arranged around the rotating member 22, and the limiting member 24 can be connected to at least part of the mounting portion 210.

[0048] It is understandable that the driving member 23 can drive the abutting portion 25 to rotate, and the abutting portion 25 drives the rotating member 22 to rotate until the abutting portion 25 abuts the limiting member 24, causing the abutting portion 25 to stop rotating and the rotating member 22 to stop rotating along with the abutting portion 25, thus reaching the maximum rotation angle that the rotating member 22 can achieve. Therefore, when the user removes the limiting member 24 from the original mounting portion 210 and connects it to the mounting portion 210 in another position, the abutting position between the abutting portion 25 and the limiting member 24 can be changed, thereby adjusting the maximum rotation angle that the rotating member 22 can achieve.

[0049] Figure 3 Display as Figure 2 The top view of Figure 2 and Figure 3In some embodiments of the present application, the rotating member 22 may include an output shaft 220 , with a plurality of mounting portions 210 spaced circumferentially along the central axis of the output shaft 220 , where the number of the plurality of mounting portions is T. The limiting member 24 may include a first limiting ring 241 and a second limiting ring 242 . The first limiting ring 241 is disposed on one side of the output shaft 220 and is capable of connecting with M mounting portions 210 ; the second limiting ring 242 is disposed on the other side of the output shaft 220 and is capable of connecting with N mounting portions 210 , where T ≥ M + N. The first limiting ring 241 and the second limiting ring 242 define a rotation space 243 , and the abutting portion 25 is disposed within the rotation space 243 .

[0050] That is to say, when the first limiting ring 241 and the second limiting ring 242 of the present application can be completely installed on multiple mounting parts 210 of the shell 21, then T=M+N, or part of the first limiting ring 241 or part of the second limiting ring 242 can be installed on part of the mounting part 210 on the shell 21, then T>M+N.

[0051] It is understandable that the present application configures the limiting member 24 as an annular structure surrounding the output shaft 220, which can improve the structural compactness of the angle adjustment device 20 while ensuring the connection strength between the limiting member 24 and the housing 21. In addition, when the abutting portion 25 rotates clockwise within the rotation space 243, the abutting portion 25 can stably abut against the first limiting ring 241; when the abutting portion 25 rotates counterclockwise within the rotation space 243, the abutting portion 25 can stably abut against the second limiting ring 242. In other words, the present application can adjust the size of the above-mentioned rotation space 243 and the rotation range of the output shaft 220 by changing the connection position of the first limiting ring 241 and the second limiting ring 242 on the housing 21.

[0052] Specifically, the closer the end of the first limiting ring 241 away from the abutment 25 is to the end of the second limiting ring 242 away from the abutment 25, the larger the rotation space 243 is, and the greater the rotation range of the output shaft 220 is. Conversely, the farther the end of the first limiting ring 241 away from the abutment 25 is from the end of the second limiting ring 242 away from the abutment 25, the smaller the rotation space 243 is, and the smaller the rotation range of the output shaft 220 is. Users can appropriately set the rotation angle according to the specific needs of the rotating screen 1 in actual application scenarios.

[0053] In some other possible structural designs of the present application, the limiting member 24 can also be set as a cylindrical structure or a polygonal column structure, etc., as long as it is set on the rotation path of the abutting portion 25 and can abut and limit it.

[0054] Figure 4 Display as Figure 2 The enlarged structural diagram at position A is shown in conjunction with Figure 2 and Figure 4 In some embodiments of the present application, the plurality of mounting portions 210 may include a plurality of connecting slots 211 provided on the housing 21, and the plurality of connecting slots 211 are circumferentially spaced apart along the central axis of the output shaft 220. A plurality of limiting blocks 244 are respectively provided on the first limiting ring 241 and the second limiting ring 242, and the plurality of limiting blocks 244 are circumferentially spaced apart along the central axis of the output shaft 220, with each limiting block 244 connected to a corresponding connecting slot 211.

[0055] In this way, when the user needs to adjust the position of the first limiting ring 241 or the second limiting ring 242, he only needs to lift the first limiting ring 241 or the second limiting ring 242 upwards, so that the multiple limiting blocks 244 located thereon are pulled out from the corresponding connecting slots 211, and then move the first limiting ring 241 or the second limiting ring 242 to a suitable position and press it down, so that the above-mentioned multiple limiting blocks 244 are inserted into another multiple connecting slots 211, and the rotation range of the angle adjustment device 20 can be adjusted conveniently.

[0056] It can be understood that, on the one hand, after the multiple limit blocks 244 on the first limit ring 241 or the second limit ring 242 are correspondingly connected to the multiple connecting slots 211 on the shell 21, the connection strength between the first limit ring 241 and the second limit ring 242 and the shell 21 can be improved, thereby preventing the first limit ring 241 and the second limit ring 242 from being separated from the shell 21 after being subjected to the force of the abutment part 25; on the other hand, during each adjustment process, the new position of the first limit ring 241 or the second limit ring 242 on the shell 21 is offset from the original position by one connecting slot 211, thereby forming a rotation space 243 of a different size from the original one, and the smaller the spacing between the multiple limit blocks 244 and their corresponding connecting slots 211, the higher the adjustment accuracy of the angle adjustment device.

[0057] Continue reading Figure 2 and Figure 4 In some embodiments of the present application, the driving member 23 may include a motor 230, the abutment portion 25 may include a sector gear 250, and the sector gear 250 is sleeved on the outer peripheral surface of the output shaft 220. The angle adjustment device 20 may also include a gear assembly 26, the input end of the gear assembly 26 is connected to the motor 230, and the output end of the gear assembly 26 is connected to the sector gear 250.

[0058] It should be noted that the sector gear 250 and the output shaft 220 are connected by a key, and the type of key can be a flat key, a semicircular key or a spline, etc. In this way, the torque of the motor 230 can be transmitted to the sector gear 250 through the gear assembly 26, and the sector gear 250 then stably transmits the torque to the output shaft 220.

[0059] Continue reading Figure 2 and Figure 4 In some embodiments of the present application, the motor 230 is disposed within the housing along a first direction F1, and the output shaft 220 extends through the housing 21 along a second direction F2. The first and second directions F1 and F2 are perpendicular to each other. A worm 231 is sleeved on the rotating shaft of the motor 230, and the friction angle of the worm 231 is smaller than the lead angle of the worm 231. The input end of the gear assembly 26 is connected to the worm 231.

[0060] Understandably, the present application allows for the motor 230 to be positioned horizontally, and the direction of power transmission can be altered through the meshing of the worm 231 and the gear assembly 26. This allows the overall structure of the angle adjustment device 20 to be relatively lightweight and aesthetically pleasing while maintaining the desired torque output direction. Furthermore, because the friction angle of the worm 231 is less than the lead angle of the worm 231, the angle adjustment device 20 can be reverse-driven, allowing the user to manually rotate the output shaft 220, which in turn drives the sector gear 250, the gear assembly 26, the worm 231, and the motor 230's shaft in the opposite direction.

[0061] In some other possible structural designs of the present application, a bevel gear may be provided on the rotating shaft of the motor 230, and another bevel gear that can mesh with the bevel gear for transmission is correspondingly provided in the gear assembly 26. In this way, the direction of power transmission can also be changed.

[0062] Continue reading Figure 2 and Figure 3 In some embodiments of the present application, the gear assembly 26 may include a first duplex gear 261 and a second duplex gear 262. The first duplex gear 261 may include a first gear and a second gear disposed coaxially, wherein the first gear has a larger pitch radius than the second gear, and the first gear is meshed with the worm 231. The second duplex gear 262 may include a third gear and a fourth gear disposed coaxially, wherein the third gear has a larger pitch radius than the fourth gear. The third gear is meshed with the second gear, and the fourth gear is connected to the sector gear 250.

[0063] It can be understood that for a gear train with a fixed transmission ratio, since the product of the rotational speed of one gear and the pitch radius is equal to the product of the rotational speed of the other gear meshing with it and the pitch radius, the rotational speed of the gear is inversely proportional to the pitch radius. In this application, the gears in the gear assembly 26 are all double gears, and the first gear with a larger pitch radius in the first double gear 261 is meshed with the worm 231, while the second gear with a smaller pitch radius in the first double gear 261 is connected to the third gear with a larger pitch radius in the second double gear 262. In this way, a larger transmission ratio can be obtained through the two double gears, so that the gear assembly 26 can reduce the high-speed motion of the motor 230 to a reasonable low-speed range through the gear assembly 26 while occupying a small installation space, and transmit it to the output shaft 220, so that the mounting tray 10 connected to the output shaft 220 and the screen body on the mounting tray 10 can rotate smoothly.

[0064] It should be noted that due to the high speed of the motor 230's shaft, the speed of the first duplex gear 261 connected to the shaft is also high, resulting in a relatively high noise level during the operation of the angle adjustment device 20. To improve this situation, in some embodiments of the present application, the material of the first duplex gear 261 can be set to a plastic material (e.g., POM, i.e., polyoxymethylene, a high-performance engineering plastic), and the speed of the second duplex gear 262 is the speed after the transmission ratio is reduced, which is relatively low and can be made of powder metallurgy. In this way, the noise generated during the operation of the angle adjustment device 20 can be reduced while ensuring that the gear assembly 26 has a large transmission ratio.

[0065] Continue reading Figure 2 and Figure 3 In some embodiments of the present application, the gear assembly 26 may further include a third duplex gear 263. The third duplex gear 263 may include a fifth gear and a sixth gear disposed coaxially, with the pitch radius of the fifth gear being greater than the pitch radius of the sixth gear. The fifth gear meshes with the fourth gear, and the sixth gear meshes with the sector gear 250.

[0066] Understandably, the third dual gear 263 can further increase the transmission ratio of the gear assembly 26, allowing the sector gear 250 and the output shaft 220 to achieve a lower rotational speed. This allows the output shaft 220 to adjust its rotation angle slowly and smoothly when the screen body on the mounting tray 10 is heavy and has a high inertia, preventing the screen body from sliding off the mounting tray 10 and ensuring safety during the angle adjustment process.

[0067] Figure 5 Display as Figure 3 The cross-sectional structure diagram at position BB, refer to Figure 3 and Figure 5 In some embodiments of the present application, the angle adjustment device 20 may further include a controller and an angle detection component 27, wherein the controller is electrically connected to the motor 230. The angle detection component 27 may include a magnetic element 271 and a magnetic encoder 272, wherein the magnetic element 271 is connected to the output shaft 220, and the magnetic encoder 272 is electrically connected to the controller. The magnetic encoder 272 can obtain rotation angle information of the magnetic element 271 in response to changes in the magnetic field of the magnetic element 271.

[0068] It can be understood that the present application can calibrate the position of the output shaft 220 through the first limit ring 241, the second limit ring 242 and the angle detection component 27, so that the output shaft 220 can be accurately rotated to the middle position of the rotation space 243 formed by the first limit ring 241 and the second limit ring 242. Specifically: when the controller controls the motor 230 to rotate forward, the driving torque of the motor 230 can be transmitted to the output shaft 220 through the first double gear 261, the second double gear 262, the third double gear 263 and the fan gear 250 in sequence, until the fan gear 250 rotates to abut against the first limit ring 241, the output shaft 220 and the magnetic element 271 set on the output shaft 220 stop rotating along with the fan gear 250, and the magnetic encoder 272 can record the position of the output shaft 220 at this time as the first angle; similarly, when the controller controls the motor 230 to rotate forward, the driving torque of the motor 230 can be transmitted to the output shaft 220 through the first double gear 261, the second double gear 262, the third double gear 263 and the fan gear 250 in sequence, until the fan gear 250 rotates to abut against the first limit ring 241, and the output shaft 220 and the magnetic element 271 set on the output shaft 220 stop rotating along with the fan gear 250, and the magnetic encoder 272 can record the position of the output shaft 220 at this time as the first angle; similarly, when the controller controls the motor 230 to rotate forward, the driving torque of the motor 230 can be transmitted to the output shaft 220 through the first double gear 261, the second double gear 262, the third double gear 263 and the fan gear 250 in sequence, When the machine 230 reverses, the sector gear 250 can rotate until it abuts against the second limit ring 242, and the output shaft 220 and the magnetic element 271 set on the output shaft 220 stop rotating along with the sector gear 250. The magnetic encoder 272 can record the position of the output shaft 220 at this time as the second angle. The magnetic encoder 272 can convert the above angle information into a corresponding electrical signal and transmit it to the controller. The controller can calculate the third angle between the first angle and the second angle, and control the motor 230 to drive the output shaft 220 to rotate to the third angle.

[0069] In this way, the angle adjustment device 20 can calibrate the position of the output shaft 220 so that the output shaft 220 can be located exactly in the middle of the rotation space 243 formed by the first limiting ring 241 and the second limiting ring 242 .

[0070] It should be noted that the magnetic element 271 may be a magnet, and the angle detection component 27 of the present application may also include a laser emitter and a photoelectric encoder. The photoelectric encoder determines the angle information of the output shaft 220 by receiving the light signal from the laser emitter.
