In the following detailed description of the application, some specific details are described in detail, and the well-known methods, processes, procedures, elements are not described in detail in order to avoid confusion of the essence of the application.

[0050] In addition, the person skilled in the art should understand that the drawings provided herein are for illustrative purposes, and the drawings are not necessarily drawn to scale.

[0051] "comprise," "containing" etc. in the entire description and claims of this specification shall be construed as having a broad meaning, rather than a restrictive or exhaustive meaning, unless otherwise indicated. That is, such terms shall be construed to cover an "include, but not limited to" meaning.

[0052] In the description of the present application, it should be understood that the terms "first", "second" and the like are used only for descriptive purposes, and cannot be construed as indicating or implying relative importance. In addition, in the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise stated.

[0053] Referring to Figure 1 and Figure 2 In the embodiments of the present application, a vehicle-mounted rotating screen is provided, which comprises:

[0054] A display screen 1 is used to display vehicle-mounted information.

[0055] A driving device 2 is used to provide rotating power and is located at the back of the display screen 1.

[0056] A gear set 3 has a plurality of gears meshing with each other, which is used to reduce the rotating speed of the rotating power and increase the torque of the rotating power.

[0057] A power input device 4 is connected between the driving device 2 and the gear set 3, which is used to transmit the rotating power output by the driving device 2 to the gear set 3.

[0058] A power output device 5 is connected between the gear set 3 and the display screen 1, which is used to transmit the rotating power after speed reduction by the gear set 3 to the display screen 1.

[0059] In the embodiments of the present application, the driving device 2 outputs rotating power, and the rotating power is finally transmitted to the display screen 1, so that the display screen 1 can rotate in the plane where it is located. It can be understood that the display screen 1 can be adjusted to a horizontal screen state or a vertical screen state according to the needs of the user. Thus, not only the viewing effect of the display screen 1 is improved, but also the operation of the user is facilitated. Further, the practicability of the display screen 1 is enhanced. Specifically, when the user needs to adjust the angle of the display screen 1, the driving device 2 first outputs rotating power, the rotating power is transmitted to the gear set 3 through the power input device 4, the speed of the rotating power is reduced and the torque of the rotating power is increased by the gear set 3 itself (this process can be referred to as speed reduction and torque increase), and then the adjusted rotating power is transmitted from the gear set 3 to the display screen 1 by the power output device 5, so that the rotation of the display screen 1 is realized.

[0060] Referring to Figure 2 and Figure 3As shown, further, the gear set 3 at least comprises a first gear 31 and a last gear 32, and can further comprise a transmission gear 33. The first gear 31 is connected with the power input device 4, through which the rotating power output by the driving device 2 can be transmitted to the first gear 31 to make the first gear 31 rotate. The last gear 32 is connected with the power output device 5, through which the rotating power reduced in rotating speed and increased in torque is transmitted to the power output device 5, and then to the display screen 1, so that the rotating power can stably drive the display screen 1 to rotate.

[0061] When the gear set 3 does not contain the transmission gear 33, the first gear 31 and the last gear 32 are directly engaged with each other. It should be noted that in this case, the diameter of the last gear 32 is greater than that of the first gear 31, so that the effect of reducing the rotating speed and increasing the torque can be achieved when the first gear 31 and the last gear 32 are engaged.

[0062] When the gear set 3 contains the transmission gear 33, the specific number of the transmission gears 33 is not particularly limited. When there is only one transmission gear 33, the transmission gear 33 can be directly engaged between the first gear 31 and the last gear 32; or the transmission gear 33 can be fixedly connected with one of the first gear 31 or the last gear 32 along the axis direction and engaged with the other one.

[0063] When the transmission gear 33 is provided in multiple, the multiple transmission gears 33 are located between the first gear 31 and the last gear 32 and are connected in sequence to form a transmission chain. For the multiple transmission gears 33 in the transmission chain, adjacent transmission gears 33 can be fixedly connected with each other along the rotating axis direction to change the spatial position of the transmitted rotating power, so that the changed rotating power and the unchanged rotating power are not located in the same plane; or adjacent transmission gears 33 can be engaged with each other to change the rotating speed of the rotating power by changing the diameter of the transmission gear 33. The first transmission gear 33 in the transmission chain should be connected with the first gear 31, and the connection mode can be directly engaged with the first gear 31 or fixedly connected with the first gear 31 along the rotating axis direction; the last transmission gear 33 in the transmission chain should be connected with the last gear 32, and the connection mode can be directly engaged with the last gear 32 or fixedly connected with the last gear 32 along the rotating axis direction.

[0064] As a preferred embodiment in the embodiments of the present application, the transmission gears 33 are provided as three, and the three transmission gears 33 are respectively a first transmission gear 331, a second transmission gear 332 and a third transmission gear 333; the first transmission gear 331 is in the same plane with the first end gear 31 and is engaged with the first end gear 31 as the first transmission gear 33 in the transmission chain; the second transmission gear 332 is coaxial with the first transmission gear 331, and the two are fixedly connected along the axial direction, and the second transmission gear 332 is used to change the spatial position of the rotary power, so that the rotary power before the change and the rotary power after the change are no longer in the same plane; the third transmission gear 333 is engaged with the second transmission gear 332, so that the second transmission gear 332 can drive the third transmission gear 333 to rotate, the third transmission gear 333 is coaxial with the last end gear 32, and the two are fixedly connected along the axial direction, so that the third transmission gear 333 drives the last end gear 32 to rotate, and the spatial position of the rotary power during transmission is changed again. Through the above structure, not only the rotary power is reduced in speed and increased in torque, but also the layout of the rotary power in the transmission process is reasonably optimized, so as to reduce the space occupied by the rotary screen in the vehicle, and further improve the practicability of the rotary screen.

When the motor outputs rotary power, the output shaft rotates, the output shaft drives the worm shaft 41 to rotate, through the engagement between the worm shaft 41 and the worm gear 42, the worm gear 42 rotates, and the worm gear 42 drives the first end gear 31 to rotate, thereby realizing the effect of transmitting the rotary power from the output shaft to the gear set 3.
