The positional relationship of the constituent elements is appropriately changed according to the direction in which the respective constituent elements are described. Therefore, the present application is not limited to the words described in the specification, and may be appropriately replaced according to circumstances.

Unless defined otherwise, technical or scientific terms used in embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure belongs. The terms "first," "second," and the like, as used in this disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "mounted," "connected," "coupled," and "connected" are to be construed broadly. For example, a fixed connection, a removable connection, or an integral connection; may be a mechanical connection, or a connection; may be directly connected, or indirectly connected through intermediate members, or may be in communication with the interior of two elements. The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art in the specific context.

In the related art, the three-dimensional stereoscopic display device includes a display assembly, and a motor and a driving assembly connected with the display assembly. The motor can drive the display assembly to rotate, and the driving assembly can drive the display assembly to display images. The motor is used for displaying images in the process of driving the display component to rotate by utilizing the persistence of vision of human eyes so as to present three-dimensional images.

However, in order to enable the driving assembly to drive the display assembly to display an image, the driving assembly needs to be connected to an external driving power supply through a power line in addition to the display assembly. The power line can influence the rotation of the display assembly, so that the display effect of the three-dimensional display device is poor.

Fig. 1 is a schematic structural view of a display device provided in an embodiment of the present disclosure, fig. 2 is a cross-sectional view of a display device provided in an embodiment of the present disclosure, fig. 3 is a schematic structural view of a driving assembly provided in an embodiment of fig. 1, and fig. 4 is a schematic structural view of a circuit board assembly provided in an embodiment of fig. 1, as shown in fig. 1 to 4, the display device includes: display assembly 5, base 1, motor 2, and drive assembly 4.

As shown in fig. 1 to 4, the driving unit 4 is disposed at a position of the display unit 5 near the base 1 side, for driving the display unit 5 to display an image.

Specifically, the drive assembly 4 includes a wireless power receiving structure 41, a wireless power transmitting structure 40, and a circuit board structure 42. Wherein the wireless power transmitting structure 40 is independent of the display assembly 5 and is used for wired connection with a driving power supply. The wireless power supply transmitting structure 40 transfers electric energy to the wireless power supply receiving structure 41 through electromagnetic mutual inductance. The circuit board structure 42 is connected with the wireless power supply receiving structure 41 and the display assembly 5, and is used for driving the display assembly 5 to display images under the action of the electric energy received by the wireless power supply receiving structure 41.

This arrangement allows the wireless power transmitting structure 40 in the driving assembly 4 to transmit the electric energy provided by the driving power source to the wireless power receiving structure 41 through electromagnetic mutual inductance, and the wireless power receiving structure 41 can further transmit the electric energy to the display assembly 5, so as to drive the display assembly 5 to display images.

Further, the motor 2 is disposed on the base 1 and connected to the display assembly 5, and is used for driving the display assembly 5 to rotate, and since the motor drives the display assembly 5 to rotate and simultaneously drives the display assembly 5 to display images through the driving assembly 4, the driving of the motor can enable the display assembly 5 to achieve the display effect of three-dimensional images.

Since the driving component 4 is internally powered by wireless power, the wireless power supply emitting structure 40 and the display component 5 are independent from each other. Therefore, when the motor drives the display assembly 5 to rotate, the driving wiring connecting the wireless power supply emission structure 40 and the driving power supply does not affect the rotation of the display assembly 5, thereby ensuring the display effect of the display device.

In addition, since the driving unit 5 is disposed at a position of the display unit 5 near the base 1 side, the center of gravity of the entire display device is located at a side of the driving unit 4 away from the display unit 5.

The audio player can be used for playing the audio corresponding to the display image in the display module. Therefore, on the premise that the user sees the image displayed by the display component 5, the user can hear the audio corresponding to the image, and the user experience is good.

As shown in fig. 1, the housing 3 is fixedly connected with the base 1 and encloses a closed space. Wherein, motor 2, drive assembly 4 and display assembly 5 all lie in the enclosure. Wherein the enclosed space may be a cylindrical space.

In some embodiments, a vacuum is within the enclosed space.

Because sound (including noise) can not propagate under vacuum, set up to vacuum state in the enclosure space, can effectively reduce the noise when motor output shaft 202, drive assembly 4 and display module 5 rotate in the enclosure space, user experience is better.

As shown in fig. 8, in some embodiments, the housing 3 has a power interface 13 thereon for connecting to a driving power source, wherein the power interface 13 is connected to the third circuit board 9, and the power interface 13 is for connecting to the driving power source. In other embodiments, the power interface 13 is connected to the third circuit board 9, and may also be used to connect to an external device, so as to modify control parameters inside the display device.

In other embodiments, the display device further includes a rubber plug that may be used to enclose the power interface 13. In the case where the power supply interface 13 is not connected to an external driving power supply, a rubber plug may be provided in the power supply interface in order to prevent foreign substances (such as dust or moisture) from entering the power supply interface. Thereby, the influence of the foreign matter on the power interface 13 is avoided, thereby ensuring the reliability of the connection of the external driving power source and the power interface 13.

It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present application, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the application, and are also considered to be within the scope of the application.
