[0049] The embodiments of this disclosure are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The rotating device 100 according to an embodiment of this disclosure is described below with reference to Figures 1-10, including a base 1, a rotating mechanism 12, a drive assembly 203, and an elastic stop device 30.

[0050] Specifically, as shown in Figures 1-10, the rotating mechanism 12 is movably connected to the base 1, and the drive assembly 20 cooperates with the rotating mechanism 12 to drive the rotating mechanism 12 to move along a predetermined trajectory; one end of the elastic stop device 30 is connected to the base 1, and the other end of the elastic stop device 30 is elastically stopped by the rotating mechanism 12.

[0051] Referring to Figures 1-10, the rotating mechanism 12 is located on one side of the base 1. The rotating mechanism 12 allows the base 1 to rotate relative to other structural components, facilitating user adjustment of the angle of the rotating device 100 as needed. The drive mechanism 26 provides power to the rotating mechanism 12, driving it to control the angle of the rotating device 100. An elastic stop device 30 is located on the side of the rotating mechanism 12 away from the drive assembly 20. The elastic stop device 30 provides damping or fixing to the rotating device 100 when it rotates to a certain position, preventing excessive movement of the base 1 due to gravity or other external forces, and maintaining the rotating device 100 at the desired tilt angle. In some embodiments, the elastic stop device 30 can be an elastic element. One end of the elastic element is fixedly connected to the base 1, and the other end abuts against the rotating mechanism 12. The other end of the elastic element contacts the side of the rotating mechanism 12 adjacent to the drive assembly 20. The elastic element can apply a certain force to the rotating mechanism 12. The engagement between the rotating mechanism 12 and the drive assembly 20 can be a gear engagement. This force helps eliminate the tooth backlash between the rotating mechanism 12 and the drive assembly 20, improving the accuracy and stability of the engagement between the rotating mechanism 12 and the drive assembly 20, avoiding vibration caused by tooth backlash during the movement of the rotating device 100, and making the movement of the rotating device 100 smoother. Furthermore, the end of the elastic element that abuts against the rotating mechanism 12 is covered with a soft rubber structure, which can reduce wear caused by hard contact between the elastic element and the rotating mechanism 12, and can also absorb some vibration, further improving the stability and service life of the rotating device 100.

[0052] According to the rotating device 100 of the present disclosure embodiment, the user can adjust the tilt angle of the rotating device 100 as needed. The drive assembly 20 can drive the rotating mechanism 12 to work. The rotating mechanism 12 can drive the rotating device 100 to rotate in a specified direction. The setting of the elastic stop device 30 can make the rotation of the rotating device 100 more stable, ensuring that the rotating device 100 will not shake unnecessarily due to excessive rotation or external force, and ensuring that the rotating device 100 can stay in the set position, thereby improving the stability and reliability of the rotating device 100 during operation and improving the user experience.

[0053] According to some embodiments of the present disclosure, as shown in Figures 3-5, the drive assembly 20 has an output end 23, and the elastic stop device 30 is disposed on the side of the rotating mechanism 12 away from the output end 23.

[0054] The output end 23 of the drive assembly 20 is adapted to cooperate with the rotating mechanism 12, and is responsible for transmitting power to the rotating mechanism 12 so that it moves along a predetermined trajectory. In some embodiments, an elastic stop device 30 is provided on the side of the rotating mechanism 12 away from the output end 23 of the drive assembly 20. The elastic stop device 30 can apply a force to the side of the rotating mechanism 12 away from the output end 23 of the drive assembly 20, forming a configuration in which the elastic stop device 30 and the output end 23 of the drive assembly 20 respectively clamp the rotating mechanism 12 from the upper and lower sides. The force applied by the elastic stop device 30 and the drive assembly 20 to the rotating mechanism 12 can effectively eliminate play and improve the transmission efficiency and stability of the rotating mechanism 12.

[0055] In some embodiments, the elastic stop device 30 and the output end 23 of the drive assembly 20 are located on the same side of the rotating mechanism 12. By stopping the rotating mechanism 12 with the elastic stop device 30, the rotating mechanism 12 abuts against the base 1 on the side away from the elastic stop device 30, thereby eliminating the play between the rotating mechanism 12 and the base 1 and improving the stability of the rotation of the rotating mechanism 12.

[0056] According to some embodiments of this disclosure, as shown in Figures 3 and 4, the elastic stop device 30 includes a first fixing member 31, a first stop member 32 and a first elastic member 33. The first fixing member 31 is disposed on the base 1; the first stop member 32 is disposed between the first fixing member 31 and the rotating mechanism 12; and the first elastic member 33 is disposed between the first fixing member 31 and the first stop member 32.

[0057] The first fixing member 31 is disposed at one end of the base 1 near the rotating mechanism 12. The surface of the first stop member 32 away from the drive assembly 20 is adapted to contact and stop with one side surface of the rotating mechanism 12. One end of the first elastic member 33 stops with the first fixing member 31, and the other end of the first elastic member 33 stops with the first stop member 32. The first elastic member 33 can apply a certain pressure to the first stop member 32.

[0058] Therefore, the first fixing member 31 serves as the basic mounting point of the elastic stop device 30, used to connect the drive assembly 20 with other components. The first stop member 32 is adapted to contact and stop with one side surface of the rotating mechanism 12. The first elastic member 33 is adapted to apply a certain pressure to the first stop member 32 to ensure close contact between the first stop member 32 and the rotating mechanism 12, thereby ensuring the stability of the rotating device 100 during rotation and avoiding unnecessary shaking.

[0059] According to some embodiments of the present disclosure, as shown in Figures 3 and 4 and Figures 9 and 10, the first stop member 32 includes a body part 40 and a movable part 50. The body part 40 is connected to the first fixing member 31; the movable part 50 is connected to the body part 40 and is movable relative to the body part 40.

[0060] The main body 40 is fixed relative to the first fixed member 31, and the movable part 50 is movable relative to the main body 40. When the first elastic member 33 applies a certain pressure to the first stop member 32, the movable part 50 of the first stop member 32 abuts against the rotating mechanism 12.

[0061] Therefore, the arrangement of the main body 40 and the movable part 50 can ensure the cooperation between the first elastic member 33 and the first stop member 32, and can also ensure the close contact between the first stop member 32 and the rotating mechanism 12, thereby ensuring the stability of the rotating device 100 during rotation and avoiding unnecessary shaking.

[0062] According to some embodiments of the present disclosure, as shown in Figures 3 and 4, a positioning groove 321 is formed on the first stop member 32, a part of the first elastic member 33 is located in the positioning groove 321, and another part of the first elastic member 33 is located outside the positioning groove 321 and stops against the first fixing member 31.

[0063] A positioning groove 321 is formed on the side surface of the first stop member 32 away from the rotating mechanism 12. The positioning groove 321 is formed by at least a portion of the side surface of the first stop member 32 away from the rotating mechanism 12 being recessed toward the adjacent rotating mechanism 12. A portion of the first elastic member 33 is embedded in the positioning groove 321. The first elastic member 33 has a C-shaped structure. The two ends of the first elastic member 33 are adapted to abut against the inner wall of the positioning groove 321. The middle part of the first elastic member 33 protrudes toward the direction away from the positioning groove 321. The protruding middle part of the first elastic member 33 is adapted to abut against the side surface of the first fixing member 31 adjacent to the rotating mechanism 12.

[0064] Therefore, the first stop member 32 has a positioning groove 321 and the first elastic member 33 cooperates with the positioning groove 321, which can ensure the assembly stability of the first elastic member 33 during the rotation of the rotating device 100, avoid the first elastic member 33 from shifting during the movement of the rotating device 100, and help improve the reliability and service life of the entire elastic stop device 30.

[0065] According to some embodiments of this disclosure, as shown in Figures 3 and 4, a positioning post 322 is provided on the inner wall of the positioning groove 321; a positioning hole 331 is formed on the first elastic member 33, and the positioning hole 331 cooperates with the positioning post 322.

[0066] One end of the positioning post 322 is adapted to connect with the bottom wall of the positioning groove 321, and the other end of the positioning post 322 extends toward the side where the first fixing member 31 is located. The positioning hole 331 is provided through the first elastic member 33 along the thickness direction of the first elastic member 33, and the positioning hole 331 is located in the middle of the first elastic member 33. The positioning post 322 is adapted to be inserted into the positioning hole 331.

[0067] Therefore, by cooperating with the positioning pin 322 in the positioning groove 321 of the first elastic member 33, the stability and positional accuracy of the first elastic member 33 during operation can be ensured. The positioning pin 322 can play a certain limiting role on the first elastic member 33, ensuring that the first elastic member 33 will not deviate during operation, thereby improving the stability and reliability of the entire elastic stop device 30.

[0068] According to some embodiments of the present disclosure, as shown in Figures 3 and 4, the positioning post 322 includes a first positioning post segment 323 and a second positioning post segment 324 connected sequentially in the direction toward the first fixing member 31. A step portion is provided between the first positioning post segment 323 and the second positioning post segment 324, and a positioning hole 331 is fitted at the second positioning post segment 324.

[0069] One end of the first positioning post segment 323 is connected to the bottom wall of the positioning groove 321, and the other end of the second positioning post segment 324 extends toward the side where the first fixing member 31 is located. One end of the first positioning post segment 323 is connected to the end face of the other end of the second positioning post segment 324, and the other end of the second positioning post segment 324 extends toward the side where the first fixing member 31 is located. Along the extension direction of the positioning post 322, the projection of the second positioning post segment 324 is located within the projection of the first positioning post segment 323, and the second positioning post segment 324 is adapted to pass through the positioning hole 331.

[0070] Therefore, when the first elastic member 33 is deformed under force, the middle part of the first elastic member 33 can move a certain distance along the extension direction of the positioning post 322. There is a step between the first positioning post segment 323 and the second positioning post segment 324. The step can limit the deformation distance of the first elastic member 33 in the extension direction of the positioning post 322, that is, limit the deformation range of the first elastic member 33, avoid the first elastic member 33 from being over-deformed and causing irreversible damage, and improve the durability and service life of the first elastic member 33.

[0071] According to some embodiments of this disclosure, as shown in Figures 3 and 4, a clearance groove 311 is formed on the first fixing member 31. The clearance groove 311 is opposite to the second positioning column segment 324 and is used to avoid the free end of the second positioning column segment 324.

[0072] A clearance groove 311 is formed on the side surface of the first fixing member 31 opposite to the first stop member 32. The clearance groove 311 is formed by at least a portion of the side surface of the first fixing member 31 opposite to the first stop member 32 being recessed in a direction away from the first stop member 32. The other end of the second positioning column segment 324 away from the first stop member 32 is adapted to fit into the clearance groove 311.

[0073] Therefore, the clearance groove 311 is designed to accommodate the free end of the second positioning post segment 324, ensuring that the free end of the second positioning post segment 324 does not interfere with the first fixing member 31, thus guaranteeing the normal operation of the entire structure. Through the cooperation of the clearance groove 311 and the second positioning post segment 324, a stable fit between the first elastic member 33 and the positioning post 322 can be ensured, preventing the first elastic member 33 from disengaging from the upper end of the positioning post 322.

[0074] According to some embodiments of this disclosure, as shown in Figures 3 and 4, the positioning groove 321 is provided with a first stop post 3211 and a second stop post 3212 spaced apart along the rotation direction of the rotating mechanism 12, and the two ends of the first elastic member 33 abut against the first stop post 3211 and the second stop post 3212.

[0075] One end of the first stop post 3211 and the second stop post 3212 is adapted to connect with the bottom wall of the positioning groove 321, and the other end of the first stop post 3211 and the second stop post 3212 is adapted to extend toward the side where the first fixing member 31 is located. Along the rotation direction of the rotating mechanism 12, there is a certain distance between the first stop post 3211 and the second stop post 3212. The first elastic member 33 has a C-shaped structure, having a first end and a second end. The first end is adapted to abut against the connection between the first stop post 3211 and the bottom wall of the positioning groove 321, and the second end is adapted to abut against the connection between the second stop post 3212 and the bottom wall of the positioning groove 321.

[0076] Therefore, the arrangement of the first stop post 3211 and the second stop post 3212 limits the range of movement of the first elastic member 33 in the rotation direction of the rotating mechanism 12, ensuring the stable installation of the first elastic member 33 in the positioning groove 321, improving the stability of the entire elastic stop device 30. The arrangement of the first stop post 3211 and the second stop post 3212 also reduces the installation difficulty of the first elastic member 33, simplifies the assembly process of the first elastic member 33, and ensures the correct installation of the first elastic member 33.

[0077] According to some embodiments of the present disclosure, as shown in Figures 3 and 4, at least one end of the first elastic member 33 has a bent portion 332, which is formed by bending the end of the first elastic member 33 in a direction away from the first stop member 32.

[0078] The bent portion 332 is formed by bending the end of the first elastic member 33 in a direction away from the first stop member 32 and in a direction close to the side surface of the first elastic member 33 adjacent to the first stop member 32. In some embodiments, both the first end and the second end of the first elastic member 33 have bent portions 332. The bent portions 332 of the first elastic member 33 are adapted to abut against the connection between the first stop post 3211 and the bottom wall of the positioning groove 321, and the bent portions 332 of the first elastic member 33 are adapted to abut against the connection between the second stop post 3212 and the bottom wall of the positioning groove 321.

[0079] Therefore, the bending portion 332 can enhance the structural strength at the end of the first elastic member 33. The bending portion 332 is suitable for fitting in the positioning groove 321. The bending portion 332 can ensure the stable fit between the first elastic member 33 and the first positioning groove 321, prevent the first elastic member 33 from accidentally coming out of the positioning groove 321, and improve the reliability of the first elastic member 33.

[0080] According to some embodiments of this disclosure, as shown in Figures 3 and 4, the first elastic member 33 is a spring sheet, and the first elastic member 33 is a protrusion protruding toward the side where the first fixing member 31 is located.

[0081] The first elastic element 33 is a C-shaped spring sheet that protrudes towards the side where the first fixing element 31 is located, forming a protrusion. Spring sheets are a commonly used elastic element; they are typically small in size and can be easily integrated into various devices. Spring sheets have a simple structure, relatively simple manufacturing process, are easy to process and install, have low production and maintenance costs, and possess good fatigue resistance, high durability, and can withstand multiple cycles of use without losing their elasticity.

[0082] Therefore, the first elastic element 33 is a spring sheet, which can effectively improve the durability of the first elastic element 33, reduce the production cost and installation difficulty of the first elastic element 33, and extend the service life of the first elastic element 33.

[0083] According to some embodiments of this disclosure, the elastic stop device 30 includes a second fixing member, a second stop member, and a second elastic member. The second fixing member is disposed on the drive assembly 20. The second stop member is disposed between the second fixing member and the rotating mechanism 12. The second elastic member is built into the second stop member, and the second stop member elastically stops the rotating mechanism 12 through the second elastic member.

[0084] In some embodiments, the second fixing member is disposed at one end of the drive assembly 20 adjacent to the rotating mechanism 12, and the second stop member is provided with a second elastic member at the end away from the drive assembly 20. The second stop member is adapted to contact and stop with one side surface of the rotating mechanism 12 through the second elastic member, and the second elastic member can apply a certain pressure to the rotating mechanism 12.

[0085] Therefore, the second fixing member serves as the basic mounting point for the elastic stop device 30, and is used to connect the drive assembly 20 with other components. The second stop member is adapted to contact and stop with one side surface of the rotating mechanism 12. The second elastic member is adapted to apply a certain pressure to the rotating mechanism 12 to ensure close contact between the second stop member and the rotating mechanism 12, thereby ensuring the stability of the base 1 during rotation and avoiding unnecessary shaking.

[0086] According to some embodiments of the present disclosure, the elastic stop device 30 includes a third fixing member and a third stop member. The third fixing member is disposed on the drive assembly 20; the third stop member stops between the third fixing member and the rotating mechanism 12, and the third stop member is an elastic stop member.

[0087] In some embodiments, the third fixing member is disposed at one end of the drive assembly 20 adjacent to the rotating mechanism 12, one end of the third stop member is adapted to stop against the third fixing member, and the other end of the third stop member is adapted to contact and stop against one side surface of the rotating mechanism 12. The third stop member is an elastic stop member, that is, the third stop member can undergo a certain elastic deformation, and the third stop member can apply a certain pressure to the rotating mechanism 12.

[0088] Therefore, the third fixing member serves as the basic mounting point of the elastic stop device 30, and is used to connect the drive assembly 20 and the third stop member. The third stop member is adapted to contact and stop with one side surface of the rotating mechanism 12. The third stop member is adapted to apply a certain pressure to the rotating mechanism 12 to ensure close contact between the third stop member and the rotating mechanism 12, thereby ensuring the stability of the base 1 during rotation and avoiding unnecessary shaking.

[0089] According to some embodiments of this disclosure, as shown in Figures 5 and 6, the drive assembly 20 includes an output end 23, the rotation mechanism 12 includes a rotating rack 13, and the elastic stop device 30 is disposed on the side of the rotating rack 13 away from the output end 23.

[0090] Output end 23 is adapted to transmit the driving force output by drive assembly 20 to rotating mechanism 12. Rotating rack 13 cooperates with output end 23 to realize the conversion of linear or rotary motion through gears or other transmission methods. Rotating rack 13 is adapted to cooperate with elastic stop device 30. The position of rotating rack 13 determines the angle of rotating device 100. When drive assembly 20 drives rotating rack 13 through its output end 23, rotating rack 13 begins to move or rotate along a predetermined trajectory, thereby causing rotating device 100 to change angle. Thus, through the cooperation between output end 23 and rotating rack 13, drive assembly 20 can flexibly adjust the angle of rotating device 100.

[0091] According to some embodiments of the present disclosure, as shown in Figures 5 and 6, the drive assembly 20 includes a drive output gear 21, which is disposed at the output end 23. The drive output gear 21 meshes with the rotating rack 13, and the drive output gear 21 and the rotating rack 13 rotate in the same or opposite directions.

[0092] That is, the drive assembly 20 outputs power to the rotating mechanism 12 through the drive output gear 21. The drive output gear 21 meshes with the rotating rack 13 of the rotating mechanism 12, driving the rotating mechanism 12 to rotate, thereby adjusting the angle of the rotating device 100. The drive output gear 21 and the elastic stop device 30 are respectively provided on both sides of the rotating rack 13 in the thickness direction. After the drive output gear 21 meshes with the rotating rack 13, the elastic stop device 30 is provided on the other side of the rotating rack 13 away from the drive output gear 21 to stop the rotating rack 13, thereby facilitating the rotating rack 13 to always maintain a tight mesh with the drive output gear 21.

[0093] Therefore, the elastic stop device 30 and the drive output gear 21 are located on both sides of the rotating rack 13. The elastic stop device 30 stops the rotating rack 13 against the drive output gear 21 to maintain good contact, preventing vehicle vibration from causing the meshing between the drive output gear 21 and the rotating rack 13 to loosen, affecting the force transmission between the drive assembly 20 and the display screen 10, improving the reliability and stability of the assembly between the drive assembly 20 and the display screen 10, reducing abnormal noise caused by loose gear meshing in the rotating device 100, preventing the rotating device 100 from shaking, and improving the user experience.

[0094] According to some embodiments of this disclosure, as shown in Figures 5 and 6, the rotating mechanism 12 includes a base plate 14 and a rotating plate 15. The rotating plate 15 is connected to the base plate 14 and extends along a predetermined trajectory. The drive assembly 20 cooperates with the rotating plate 15. When the drive assembly 20 is working, the drive assembly 20 drives the base plate 14 to rotate via the rotating plate 15.

[0095] In this embodiment, the rotating mechanism 12 is located behind the base 1. The rotating mechanism 12 includes a base plate 14 and a rotating plate 15 connected to each other. One end of the base plate 14 and the rotating plate 15 are connected to each other. The rotating plate 15 has an arc-shaped structure, and the rotating plate 15 is bent from the end connected to the base plate 14 toward the end of the drive output gear 21 to form an arc-shaped structure. A rotating rack 13 is provided on the side surface of the rotating plate 15 away from the rotation center of the rotating plate 15. That is, the rotating rack 13 is provided on the side of the rotating plate 15 away from the base plate 14. The rotating rack 13 meshes externally with the drive output gear 21. The rotating plate 15 rotates relative to the drive output gear 21 around the rotation center of the rotating plate 15 to realize the adjustment of the angle of the base plate 14. Thus, the arrangement of the base plate 14 and the rotating plate 15 facilitates the angle adjustment of the base plate 14 when the rotating mechanism 12 moves. At the same time, the rotating plate 15 facilitates the arrangement of the rotating rack 13 so that when the drive assembly 20 is working, the base plate 14 can be rotated at a predetermined angle and the position of the base plate 14 can be adjusted.

[0096] According to some embodiments of the present disclosure, as shown in FIG7, the base 1 includes a housing 22, on which two sliding grooves 70 are formed at intervals along the rotation direction perpendicular to the rotating plate 15; at least one rolling element 60 is provided on each side of the rotating plate 15, and the rolling element 60 is rotatably engaged in the sliding groove 70.

[0097] That is, rolling elements 60 are respectively provided on both sides of the rotating plate 15 along the center line of the rotation center. When the rotating plate 15 rotates, the rotating plate 15 slides with the housing 22. The housing 22 forms grooves 70 spaced apart along the center line, and the rolling elements 60 cooperate with the corresponding grooves 70. Specifically, support shafts are respectively provided on both sides of the rotating plate 15 where the rolling elements 60 are provided, and the rolling elements 60 rotate with the support shafts. In this embodiment, in order to facilitate the stable rotation of the base 1 by the rotating plate 15, two rolling elements 60 are respectively provided on the side walls of the rotating plate 15 along the center line. This increases the support of the rolling elements 60 for the rotating plate 15 when it cooperates with the housing 22, increases the stability and smoothness of the rotation of the rotating plate 15 driven by the drive output gear 21, and reduces the friction during the rotation process of the rotating plate 15 and the housing 22. At the same time, the grooves 70 are formed on the housing 22 to limit the rolling elements 60 and prevent them from falling out of the grooves 70.

[0098] Furthermore, as shown in Figure 7, the rolling element 60 remains in contact with the bottom wall of the groove 70 under the action of the elastic stop device 30.

[0099] The elastic stop device 30 stops the rotating mechanism 12, so that the rotating mechanism 12 and the drive output gear 21 are effectively engaged. At the same time, during the rotation of the rotating plate 15, the elastic stop device 30 can keep the rolling element 60 in contact with the bottom wall of the slide groove 70, so that the rotating plate 15 has good guidance during the rotation, avoids the base 1 from shaking during the rotation, and improves the assembly accuracy and reliability of the rotating device 100.

[0100] According to some embodiments of the present disclosure, as shown in FIG7, the drive assembly 20 includes at least one limiting member 24; at least one limiting groove 152 is formed on the rotating plate 15, the limiting groove 152 extends along the rotation direction of the rotating plate 15, and the limiting member 24 is engaged in the limiting groove 152 to limit the rotation limit position of the substrate 14.

[0101] In this embodiment, a limiting groove 152 is formed on both sides of the rotating rack 13 on the rotating plate 15. The limiting groove 152 extends along the length of the rotating plate 15. The limiting member 24 passes through the housing 22 from the side away from the substrate 14 and engages with the limiting groove 152. The limiting groove 152 and the limiting member 24 can rotate relative to each other. For example, the limiting member 24 is fixed on the housing 22, and the free end of the limiting member 24 engages with the limiting groove 152. When the drive assembly 20 drives the rotating plate 15 to rotate, the position of the limiting groove 152 relative to the limiting member 24 changes in the rotation direction of the rotating plate 15. As the limiting groove 152 moves, when the end of the limiting groove 152 adjacent to the substrate 14 abuts against the limiting member 24, the substrate 14 can be retracted. When the end of the limiting groove 152 away from the base 1 abuts against the limiting member 24, the substrate 14 is set at a certain angle. For example, in Figure 1, the angle of rotation of the substrate 14 is 50°. Therefore, the setting of the limiting member 24 can limit the rotation angle of the rotating plate 15, avoid the excessive rotation angle of the substrate 14 from affecting the user's viewing angle, and realize the limiting of the rotation angle of the rotating plate 15, so that when the limiting member 24 is located at both ends of the limiting groove 152, the stability of the rotating plate 15 in maintaining the current position can be increased.

[0102] According to some embodiments of this disclosure, as shown in FIG7, the housing 22 includes a first housing 221, a second housing 222, and a drive mechanism 26. The second housing 222 is disposed on the side of the first housing 221 away from the elastic stop device 30. The second housing 222 and the first housing 221 together define a receiving space 223. The limiting member 24 passes through the second housing 222 and the first housing 221 and connects the second housing 222 and the first housing 221. The free end of the limiting member 24 is fitted in the limiting groove 152. The drive mechanism 26 is disposed in the receiving space 223.

[0103] That is, the drive assembly 20 includes a first housing 221 and a second housing 222 connected by a limiting member 24. The limiting member 24 slides into a limiting groove 152 after passing through the first housing 221 and the second housing 222. The limiting member 24 includes a first connecting section 241 and a second connecting section 242 connected together. The first connecting section 241 is a threaded section, that is, the outer peripheral side of the first connecting section 241 is threaded for connecting with the first housing 221 and the second housing 222. The second connecting section 242 is a straight section, that is, the outer peripheral side of the second connecting section 242 is a smooth arc surface. The second connecting section 242 extends out of the first housing 221 away from the second housing 222 and engages with the limiting groove 152 on the rotating plate 15. The drive mechanism 26 is located between the first housing 221 and the second housing 222. The end of the rotating plate 15 away from the substrate 14 extends into the space between the first housing 221 and the second housing 222 and cooperates with the drive output gear 21 to realize the rotation of the substrate 14 relative to the housing 22.

[0104] According to some embodiments of this disclosure, as shown in Figures 5-7, the drive assembly 20 includes a drive output gear 21; a rotating plate 15 is provided with a rotating rack 13, which meshes with the drive output gear 21; there are multiple limiting grooves 152, which are respectively located on both sides of the rotating rack 13 along the rotation direction perpendicular to the rotating plate 15; there are multiple limiting members 24, which are respectively fitted into the multiple limiting grooves 152.

[0105] That is, the rotating plate 15 is connected to the back of the base 1 via the base plate 14, and the other end of the rotating plate 15 extends into the housing 22. A rotating rack 13 is provided on the side of the rotating plate 15 away from the base 1, and the rotating rack 13 cooperates with the drive output gear 21. The rotating plate 15 is provided with two limiting grooves 152, which are respectively provided on both sides of the rotating rack 13 and extend along the rotation direction of the rotating plate 15. When the rotating plate 15 is assembled with the housing 22, the limiting member 24 provided in the housing 22 cooperates with the limiting groove 152. Thus, the provision of multiple limiting members 24 and limiting grooves 152 can improve the reliability of the assembly of the rotating plate 15 and the housing 22, so that the rotating plate 15 is more stable during rotation, reducing the impact of vibration transmitted by the vehicle on the stability of the rotating device 100 on the road surface, and reducing the shaking and abnormal noise of the rotating device 100.

[0106] According to some embodiments of this disclosure, as shown in Figures 5-10, the drive assembly 20 includes a damping wheel 25, which cooperates with the rotating mechanism 12.

[0107] In this embodiment, a damping wheel 25 is also provided inside the housing 22. The damping wheel 25 cooperates with the rotating rack 13. The damping wheel 25 and the drive output gear 21 are located on the side of the rotating plate 15 where the rotating rack 13 is located, and the drive output gear 21 and the damping wheel 25 are spaced apart along the rotation direction of the rotating plate 15. When the drive assembly 20 drives the rotating device 100 to rotate the angle of the adjusting base plate 14, the drive output gear 21 is the driving gear relative to the rotating rack 13, and the rotating rack 13 is the driven gear. When the torque is transmitted from the drive output gear 21 to the damping wheel 25, the drive output gear 21 is the driving gear, and the damping wheel 25 is the driven gear. The damping wheel 25 and the drive output gear 21 are located on the same side of the rotating rack 13.

[0108] When the base 1 rotates, the rotating rack 13 is driven by the output gear 21. At this time, the teeth of the rotating rack 13 are tightly engaged with the teeth of the output gear 21. For example, if the output gear 21 rotates clockwise, the rotating rack 13 rotates counterclockwise. The first surface of the teeth of the output gear 21 contacts the teeth of the rotating rack 13, pushing the rotating rack 13 to rotate. The rotating rack 13, as the driving gear, also drives the damping wheel 25, which is the driven wheel, to rotate. The teeth of the damping wheel 25 are engaged with the teeth of the rotating rack 13. At this time, the second surface of the teeth of the rotating rack 13 contacts the teeth of the damping wheel 25, pushing the damping wheel 25 to rotate. That is, the output gear 21 and the damping wheel 25 fix the rotating rack 13 in its current position, effectively eliminating the tooth gap between the rotating rack 13 and the gears in front and behind. Since the rotating device 100 has a self-locking function and cannot be reversed, and the output gear 21 provides a certain resistance, the self-locking effect of the rotating device 100 can be increased. The resistance provided by the damping wheel 25 can also prevent the rotating device 100 from shaking due to the tooth gap when it descends, making the movement of the rotating device 100 more stable.

[0109] The drive mechanism 26 also includes a clutch 27 and a drive motor 28. The clutch 27 is located between the drive motor 28 and the drive gear. One end of the clutch 27 engages with the drive gear of the drive motor 28, and the other end engages with the drive output gear 21. In addition to serving as a manual clutch, it also acts as a drive shaft. A secondary helical gear 271 is press-fitted onto one end of the clutch inner shaft 272. The other end of the clutch inner shaft 272 is sequentially assembled with a damping plate 273, a connecting housing 274, a damping plate 273, a spring plate assembly 275, and another damping plate 273, and secured with a nut 276. The clutch inner shaft 272 is fixed to the output drive shaft 29 with screws through the threaded holes on the connecting housing 274. The drive output gear 21 is mounted on the output drive shaft 29, thus assembling the clutch 27 into a single unit. Since the clutch 27 is equipped with a drive output gear 21 and a secondary helical gear 271 at its two ends, it is convenient to transmit the torque of the drive motor 28 to the rotating rack 13, thereby simplifying the structure of the drive mechanism 26, reducing the complexity of the shaft composition, and reducing transmission problems caused by assembly precision.

[0110] A semi-open damping sleeve 291 is installed on the output drive shaft 29 on which the clutch 27 is mounted. The damping sleeve 291 is interference-fitted with the output drive shaft 29 in the drive assembly 20. It is pressed down by the first housing 221 to achieve a tight fit with the output drive shaft 29. This ensures that the force transmission on the drive mechanism 26 needs to overcome the friction between the damping sleeve 291 and the output drive shaft 29 before it can move. This increases the stability of torque transmission in the drive mechanism 26 and effectively solves the problem of the rotating device 100 wobbling back and forth due to assembly gaps.

[0111] The bushing used in the rotating device 100 has an outer square and inner round design. For example, a square bushing is provided at the end of the output shaft of the drive motor 28 to prevent the bushing from rotating relative to the housing 22, reducing the noise generated by the rotating device 100 during operation. The square plastic bushing is fixed on three sides by the second housing 222 and pressed by the first housing 221, that is, it is located between the first housing 221 and the second housing 222 and limited by the first housing 221 and the second housing 222. This can reduce the number of high-precision parts required and facilitate production and cost control. The front end of the output shaft of the drive motor 28 that it cooperates with adopts a spherical structure. This reduces the friction area when the shaft rotates relative to the bushing without affecting the mating length, thus increasing the service life of the bushing.

[0112] In addition, a shielding assembly is added behind the base 1 to shield the gap between the rotating mechanism 12 and the housing 22. A spring slider system is also installed on the side wall of the shielding assembly. The system includes a shielding plate, a stop block, a fixing block, a telescopic spring, and a guide shaft. The fixing block is located on the shielding plate, and the guide shaft is located between two spaced-apart fixing blocks and a stop block. The telescopic spring is sleeved on the guide shaft, and the stop block can move along the guide shaft. The telescopic spring can constantly push the stop block to be located in the gap between the rotating mechanism 12 and the housing 22, increasing the sealing of the rotating device 100 and further improving the aesthetics of the product.

[0113] The housing 22 is also equipped with buttons, and the control board is located on the housing 22. The buttons are electrically connected to the control board, and the drive assembly 20 is electrically connected to the control board. The buttons can control the rotation angle of the base plate 14.

[0114] As shown in FIG11, the display device 1000 according to the second aspect embodiment of the present disclosure includes the rotating device 100 and the display screen 10 of the first aspect embodiment of the present disclosure, and the rotating mechanism 12 is fixedly connected to the display screen 10.

[0115] The display device 1000 includes a display screen 10. One side surface of the display screen 10 is connected to a substrate 14. When the substrate 14 rotates, it can drive the display screen 10 to rotate, so that the display screen 10 can rotate together with the substrate 14 to realize the angle adjustment function of the display screen 10.

[0116] According to the embodiments of the present disclosure, by applying the rotating device 1000 in the above embodiments, the functionality and stability of the display device 1000 can be improved, the angle adjustment of the display device 1000 can be flexibly achieved, and the user experience can be enhanced.

[0117] A vehicle 2000 according to a third aspect embodiment of the present disclosure includes a display device 1000 according to the second aspect embodiment of the present disclosure, as shown in FIG12.

[0118] Specifically, referring to Figures 1-10, the drive motor 28 of the drive mechanism 26 drives the clutch 27 to move, which in turn drives the drive output gear 21 to rotate. The drive output gear 21 engages with the rotating rack 13, which is located on the side of the rotating plate 15 away from the base 1, thus driving the rotating plate 15 to rotate. When the rotating plate 15 rotates, the rolling elements 60 on both sides of the rotating plate 15 move relative to the sliding groove 70 on the housing 22, and the limiting member 24 moves relative to the limiting groove 152 within the limiting groove 152. One end of the rotating plate 15 is connected to the base plate 14, which is connected to the base 1. Therefore, the rotation of the rotating plate 15 can drive the base 1 to rotate, thereby realizing the rotation process of the rotating device 100. The elastic stop device 30 makes the rotation of the rotating device 100 more stable, ensuring that the rotating device 100 will not shake unnecessarily due to excessive rotation or external force.

[0119] According to the vehicle 2000 of the present disclosure embodiment, the display device 1000 has good stability and reliability when rotating, which can effectively avoid the impact of the vibration of the vehicle 2000 on the stability of the display device 1000, keep the display device 1000 from shaking due to the vibration of the vehicle 2000, and the assembly structure is simple, which is conducive to improving the user experience.
