[0003] In the related art of in-vehicle display screens, a rotation structure is provided to facilitate a driver to adjust the in-vehicle display screen to a suitable angular position at any time, so as to facilitate the operation of the in-vehicle display screen. For example, Chinese Patent CN218228867U discloses a multi-angle rotation mechanism for an in-vehicle central control screen. By providing a left-right rotation actuator and a front-back rotation actuator, the in-vehicle central control screen can be rotated at two angles, namely front-back and left-right. By providing a torque damper and an angle sensor, while achieving the required functions of the product, the assembly is simple, and the reverse driving torque is relatively stable and smooth.

[0004] In the rotation structure of the in-vehicle display screen in the related art, the angle sensor is fixedly installed below the damper, and the rotation angle is detected through the synchronous transmission of the damper. However, when the damper needs to be adjusted, since the angle sensor is fixedly installed below the damper, this causes inconvenience to the adjustment or installation of the damper, and may also affect the detection accuracy of the angle sensor during the process of adjusting or installing the damper.

Detailed implementation manners

[0029] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the embodiments of the present invention.

[0030] In addition, the terms first, second, third, etc. in the specification and claims are only used for the purpose of distinguishing the description of the same technical features, and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features, nor necessarily describing the order or time sequence. The terms can be interchanged where appropriate. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature.

[0031] Similarly, the term "connected" is also used in the specification and claims and should not be construed as being limited to direct connection. Therefore, the expression "device A is connected to device B" should not be limited to device A being directly connected to device B in the device or system. It means that there is a path between device A and device B, which can be a path including other devices or tools.

[0032] The in-vehicle display screen is provided with a rotating structure to facilitate the driver to adjust the in-vehicle display screen to a suitable angular position at any time for the operation of the in-vehicle display screen. In the related technology of the rotating structure of the in-vehicle display screen, the in-vehicle display screen can be rotated in two angles, front-back and left-right, and a damper and an angle sensor are provided. In the related technology, the angle sensor is fixedly installed below the damper and detects the rotation angle through the synchronous transmission of the damper. However, when the damper needs to be adjusted, since the angle sensor is fixedly installed below the damper, it is inconvenient for the adjustment or installation of the damper, and the detection accuracy of the angle sensor may also be affected during the process of adjusting or installing the damper.

[0033] Therefore, the embodiment of the present utility model designs a rotating structure of an in-vehicle display screen, which can realize the flipping of the in-vehicle display screen in two angles, up-down and left-right, and separately arranges the angle sensor and the damper assembly without affecting the adjustment and installation of the damper assembly.

[0034] For a rotating structure of an in-vehicle display screen according to an embodiment of the present utility model, please refer to Figure 1 , which includes a first rotating mechanism 1, a second rotating mechanism 2, and an in-vehicle display screen 3; please refer to Figure 2 , Figure 3 and Figure 5 . The first rotating mechanism 1 includes a driving motor 11, a gearbox 12, a first rotating shaft 13, a damper assembly 14, and an angle sensing assembly 15. The input end and the output end of the gearbox 12 are respectively in transmission connection with the driving motor 11 and the first rotating shaft 13, that is, the driving motor 11 can drive the first rotating shaft 13 to rotate through the gearbox 12, and the damper assembly 14 is arranged on the first rotating shaft 13. Please refer to Figure 6 . The angle sensing assembly 15 includes a second rotating shaft 151, a transmission member 152, and an angle sensor 153. Please refer to Figure 6 and Figure 7The second rotating shaft 151 is rotatably fixed to the gearbox 12 and is in transmission connection with the first rotating shaft 13 via a transmission member 152. When the first rotating shaft 13 rotates, the transmission member 152 drives the second rotating shaft 151 to rotate. The angle sensor 153 is used to sense the rotation angle of the second rotating shaft 151. Because the first rotating shaft 13 and the second rotating shaft 151 are in transmission connection, once the angle sensor 153 senses the rotation angle of the second rotating shaft 151, the angle of the first rotating shaft 13 can be indirectly detected by utilizing the transmission relationship between the first rotating shaft 13 and the second rotating shaft 151. The end of the second rotating mechanism 2 is connected to the first rotating shaft 13, and when the first rotating shaft 13 rotates, it drives the second rotating mechanism 2 to rotate. The in-vehicle display screen 3 is fixed to the second rotating mechanism 2 and can rotate vertically. In the rotating structure of the in-vehicle display screen of this embodiment of the utility model, when the drive motor 11 drives the first rotating shaft 13 to rotate via the gearbox 12, the first rotating shaft 13 drives the second rotating mechanism 2 to rotate, and simultaneously drives the second rotating shaft 151 to rotate via the transmission member 152.

[0035] Specifically, when the drive motor 11 in the first rotating mechanism 1 drives the first rotating shaft 13 to rotate through the gear box 12, it drives the second rotating mechanism 2 connected to the first rotating shaft 13 to rotate, thereby driving the vehicle-mounted display screen 3 to rotate left and right. At the same time, the first rotating shaft 13 drives the second rotating shaft 151 to rotate through the transmission member 152. Since the rotation angle of the second rotating shaft 151 can be detected by the angle sensor 153, the rotation angle of the first rotating shaft 13 and the rotation angle of the second rotating mechanism 2 can be indirectly obtained, and then the rotation angle of the vehicle-mounted display screen 3 in the left and right directions can be obtained. Therefore, the embodiment of the utility model can realize the left and right electric flipping of the vehicle-mounted display screen 3 while detecting the left and right rotation angle of the display screen 3. The rotating structure of the vehicle-mounted display screen of the embodiment of the utility model, by fixing the vehicle-mounted display screen 3 to the second rotating mechanism 2 so that the vehicle-mounted display screen 3 can be rotated up and down, can also realize the manual flipping of the vehicle-mounted display screen 3 up and down, thereby adjusting the up and down angle of the vehicle-mounted display screen 3.

[0036] The rotating structure of the vehicle-mounted display screen of the embodiment of the present utility model converts the detection of the left and right rotation angles of the vehicle-mounted display screen 3 or the detection of the rotation angle of the first rotating shaft 13 into the detection of the rotation angle of the second rotating shaft 151, so that the angle sensor 153 and the damper assembly 14 can be set separately, avoiding the angle sensor 153 and the damper assembly 14 from being installed together, preventing the damper assembly 14 from affecting the detection accuracy of the angle sensor 153 during the adjustment and installation process, and preventing the angle sensor 153 from affecting the adjustment and installation of the damper assembly 14.

[0037] To achieve the rotation of the first rotating shaft 13 to drive the second rotating mechanism 2 to rotate left and right and the up-and-down rotation of the vehicle-mounted display screen 3 relative to the second rotating mechanism 2, as a preferred solution of the embodiment of the present invention, please refer to Figure 2 , Figure 3 and Figure 5 , the first rotating shaft 13 is vertically arranged at the output end of the gearbox 12, and the driving motor 11 is used to drive the gearbox 12 to drive the first rotating shaft 13 to rotate. Please refer to Figures 2 - 4 , the second rotating mechanism 2 includes a connecting arm 21, a third rotating shaft 22, and a connecting plate 23; the top end of the first rotating shaft 13 is fixedly connected to one end of the connecting arm 21, and when the first rotating shaft 13 rotates, it drives the connecting arm 21 arranged at the top end to rotate. The third rotating shaft 22 is rotatably and horizontally arranged at the other end of the connecting arm 21; the connecting plate 23 is fixedly installed on the third rotating shaft 22, and the vehicle-mounted display screen 3 is fixedly installed on the connecting plate 23, so that the vehicle-mounted display screen 3 can rotate up and down at the other end of the connecting arm 21 through the connecting plate 23. Since the first rotating shaft 13 is vertically arranged, when the first rotating shaft 13 is driven to rotate by the driving motor 11, it can drive the connecting arm 21 to rotate left and right, thereby driving the connecting plate 23 and the vehicle-mounted display screen 3 to flip left and right. Since the third rotating shaft 22 is horizontally arranged, when an up-and-down flipping force is applied to the vehicle-mounted display screen 3, the vehicle-mounted display screen 3 can be manually flipped up and down under the action of the connecting plate 23 and the third rotating shaft 22.

[0038] In the embodiment of the present invention, the connecting arm 21 is horizontally arranged. Please refer to Figure 4 , a clamping groove 211 is provided at the bottom of one end of the connecting arm 21, and the upper end of the first rotating shaft 13 is inserted into the clamping groove 211 and is clamped and fixedly connected to the connecting arm 21, so that when the first rotating shaft 13 rotates, it can drive the connecting arm 21 to rotate left and right. Through holes for bearing rotation connection 212 are provided on the left and right sides of the other end of the connecting arm 21; the third rotating shaft 22 passes through the through holes for bearing rotation connection 212 and is rotatably and fixedly arranged on the through holes for bearing rotation connection 212, so as to realize that the third rotating shaft 22 is rotatably and horizontally arranged at the other end of the connecting arm 21. A rotating shaft connection part 231 is provided on one side of the connecting plate 23 close to the connecting arm 21, and the two ends of the third rotating shaft 22 are respectively inserted into the rotating shaft connection part 231 and are fixedly connected to the rotating shaft connection part 231, so that the connecting plate 23 can rotate up and down at the other end of the connecting arm 21; the vehicle-mounted display screen 3 is fixedly installed on the connecting plate 23 through bolts 232. When an up-and-down flipping force is applied to the vehicle-mounted display screen 3, the vehicle-mounted display screen 3 can be manually flipped up and down under the action of the connecting plate 23 and the third rotating shaft 22.

[0039] To facilitate the transmission between the first rotating shaft 13 and the second rotating shaft 151, in the embodiment of the present invention, please refer to Figure 6 and Figure 7, the second rotating shaft 151 is vertically arranged rotatably on the top of the gearbox 12; please refer to Figure 6 , the transmission member 152 includes a first gear 1521 and a second gear 1522. The first gear 1521 is fixedly sleeved on the first rotating shaft 13, and the second gear 1522 is fixedly sleeved on the second rotating shaft 151. The first gear 1521 and the second gear 1522 are meshed. When the first rotating shaft 13 rotates, the first gear 1521 rotates synchronously. Due to the meshing of the first gear 1521 and the second gear 1522, the second gear 1522 is driven to rotate, thereby driving the second rotating shaft 151 to rotate. The angle sensor 153 senses the rotation angle of the second rotating shaft 151. Due to the transmission relationship between the first gear 1521 and the second gear 1522, the detection of the rotation angle of the first rotating shaft 13 is converted into the detection of the rotation angle of the second rotating shaft 151, so as to detect the rotation angle of the vehicle-mounted display screen 3 in the left-right direction.

[0040] Since the angle sensing assembly 15 in the embodiment of the present invention is mainly arranged on the top of the gearbox 12, in order to avoid the problem of the increase in the overall structural height caused by the arrangement of the angle sensing assembly 15, in the embodiment of the present invention, please refer to Figure 7 , the gearbox 12 includes a housing 121; the housing 121 includes a first housing part 1211 and a second housing part 1212 which are connected; the top of the second housing part 1212 is lower than the top of the first housing part 1211; the second rotating shaft 121 is vertically arranged rotatably on the top of the second housing part 1212.

With such a setting, when the first rotating shaft 13 rotates, it drives the second rotating shaft 151 to rotate, thereby driving the magnetic member 1511 arranged at the upper end of the second rotating shaft 151 to rotate. By setting the magnetic coding inductor as the angle sensor 153, the magnetic coding inductor is used to identify and sense the rotation angle of the magnetic member 1511 to detect the rotation angle of the second rotating shaft 151, and using the transmission relationship between the first gear 1521 and the second gear 1522, it is indirectly converted to detect the rotation angle of the first rotating shaft 13, and further detect the rotation angle of the vehicle-mounted display screen 3 in the left-right direction.
