[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a revolving display device includes a base 1, a connecting shaft 2, a motor 3, a main board 4 and a roller 5. The connecting shaft 2 is arranged on one side of the base 1. The motor 3 is covered with a shell, and the shell is fixedly sleeved on the connecting shaft 2. The main board 4 is arranged on one side of the shell and is electrically connected to the motor 3. The output shaft of the motor 3 is parallel to the connecting shaft 2. The roller 5 is rotatably sleeved on the connecting shaft 2 and encloses the main board 4 and the motor 3. The motor 3 can drive the roller 5 to rotate around the connecting shaft 2.

[0029] Specifically, the mainboard 4 can be connected to an external power supply through an electric wire; various time information can be recorded on the drum 5, such as numbers representing "hours", numbers representing "minutes", numbers representing "seconds", numbers representing years, numbers representing months, numbers representing dates, etc. In this way, the rotary display device has more information that can be displayed, including but not limited to time information, and the drum 5 can also be used to display information such as temperature and humidity. Of course, for the display of information such as temperature and humidity, it is necessary to provide a thermometer, a hygrometer and other sensors in the base 1, and the motor 3 drives the drum 5 to rotate according to the feedback information of the thermometer and the hygrometer. Of course, a page turning structure can also be installed on the outside of the drum 5, so that the rotary display device becomes a rotary page turning clock; a display frame for selecting time information can be added to the base 1, so that the user can use the time information moved to the display frame as the standard; the output shaft of the motor 3 can be provided with a rubber wheel, and the side wall of the rubber wheel abuts against the arc-shaped inner wall of the drum 5. Due to the large friction of the rubber, when the output shaft of the motor 3 rotates, the drum 5 can be driven to rotate by the rubber wheel (not shown in the figure).

[0030] like Figure 2 As shown, in one embodiment, the connecting axis 2 is parallel to the adjacent side wall of the base 1 .

[0031] In one embodiment, the axis of the connecting shaft 2 is perpendicular to the adjacent side wall of the base 1 (not shown in the drawings).

[0032] In this embodiment, the main board 4 can control the motor 3 to drive the drum 5 to rotate a certain angle around the connecting shaft 2 at a certain interval (such as one second, one minute or one hour) to change the time information located in the display frame to achieve the effect of running time, so that the motor 3 is started once at a certain interval and works intermittently, thereby increasing the torque of the motor 3, improving the working efficiency of the motor 3, avoiding continuous rotation of the motor 3, reducing the overall power consumption of the revolving display device, and reducing the noise generated by the transmission. At the same time, arranging the motor 3 on the inner side of the drum 5 can improve the space utilization rate of the revolving display device, making the device more compact and improving the user experience. The main board 4 and the motor 3 can be purchased through market channels and are not elaborated in this embodiment.

[0033] Furthermore, a sensing member 6 is disposed on the main board 4 , and a trigger member 7 is correspondingly disposed on the side wall of the drum 5 . Rotating the drum 5 can make the trigger member 7 approach or move away from the sensing member 6 . When the trigger member 7 approaches the sensing member 6 , the sensing member 6 can be triggered.

[0034] Specifically, the drum 5 has an absolute position, and when the drum 5 is at the absolute position, the triggering member 7 will trigger the sensing member 6 .

[0035] In one embodiment, the main board 4 is arranged at one end of the motor 3 away from the output shaft, the sensing member 6 is a mechanical switch, such as a micro switch, and the trigger member 7 is a protrusion, which is arranged on the end wall of the inner cavity of the drum 5 close to the main board 4. The drum 5 can be rotated to make the protrusion approach and trigger the mechanical switch (not shown in the drawings).

[0036] In one embodiment, the main board 4 is arranged at one end of the motor 3 away from the output shaft, the sensing element 6 is a light sensor, such as an optocoupler, and the trigger element 7 is an annular plate, which is coaxially arranged on the end wall of the inner cavity of the drum 5 close to the main board 4. The annular plate is partially located between the transmitting end and the receiving end of the optocoupler. A notch is provided on the annular plate. Under normal circumstances, the annular plate separates the optocoupler. When the annular plate rotates with the drum 5 to move the notch to the optocoupler, the transmitting end and the receiving end of the optocoupler can be connected through the notch, thereby triggering the optocoupler (not shown in the drawings).

[0037] In this embodiment, the main board 4 is arranged on one side of the motor 3, and the trigger member 7 is correspondingly arranged at the eccentric position of the roller 5 close to one end of the motor 3. Taking the roller 5 starting to rotate from the absolute position as an example, when the rotary display device is turned on and used, the main board 4 will control the motor 3 to drive the roller 5 to rotate, so that the roller 5 rotates to the absolute position (equivalent to finding the origin), and then the main board 4 controls the roller 5 to rotate so that the displayed time matches the real time. After that, the roller 5 rotates regularly under the drive of the motor 3, and whenever the roller 5 rotates to the absolute position, the trigger member 7 will trigger the induction member 6 to send an electrical signal, so the main board 4 can The number of rotations of the drum 5 is determined by the number of triggering times of the sensing element 6. Every time the drum 5 rotates one circle, the mainboard 4 will compare the rotation data of the motor 3, and then calibrate the motor 3 to eliminate the error. For example, the motor 3 drives the drum 5 to rotate 6 degrees every minute, and the drum 5 rotates one circle every 60 times. If the drum 5 has not reached the absolute position after rotating 60 times due to the error of the motor 3, it means that the drum 5 rotates slowly. At this time, the mainboard 4 will control the motor 3 to drive the drum 5 to rotate to the absolute position, so as to achieve the purpose of calibrating the displayed time. The same is true when the drum 5 rotates too fast, thereby avoiding inaccurate time and improving the user experience.

[0038] Furthermore, the induction element 6 is a magnetic induction element, and the trigger element 7 is a magnet.

[0039] Furthermore, the magnetic sensor is a Hall sensor.

[0040] Specifically, the sensing element 6 can be a magnetoresistive sensor or a Hall sensor. In the present embodiment, the Hall sensor is preferably a Hall sensor. The Hall sensor can preset a Hall voltage value, which is a trigger value. When the magnet rotates with the drum 5 and approaches the Hall sensor, the magnetic field strength around the Hall sensor will gradually increase, causing the Hall voltage of the Hall sensor to rise. When the distance between the magnet and the Hall sensor is short, the Hall voltage of the Hall sensor reaches the trigger value, and the Hall sensor will send an electrical signal to the main board 4. The main board 4 will count once, so the main board 4 can judge the number of rotations of the drum 5 by the number of times the Hall sensor trigger value is reached.

[0041] Furthermore, an internal tooth structure 51 is provided on the inner wall of the drum 5 in the circumferential direction, and a gear 31 is sleeved on the output shaft of the motor 3. The gear 31 meshes with the internal tooth structure 51. The output shaft of the motor 3 can drive the gear 31 to rotate, and the gear 31 will drive the drum 5 to rotate around the connecting shaft 2 through the internal tooth structure 51.

[0042] like Figure 4 As shown, further, a plurality of flippable pages 8 are distributed along the circumferential direction on the outer wall of the drum 5, and different time information is marked on the pages 8 in sequence, so that the drum 5 can be used as a page turning wheel to provide different time display modes for the rotary display device.

[0043] Furthermore, the drum 5 is rotatably connected to the connecting shaft 2 via the bearing 9 to reduce the friction resistance encountered by the drum 5 during rotation, improve the rotation smoothness of the drum 5, reduce the driving power consumption of the motor 3, and further enhance the energy-saving effect.

[0044] Furthermore, a bracket 11 is vertically provided on the top wall of the base 1, and the connecting shaft 2 is horizontally arranged on the bracket 11. The wires of the mainboard 4 can be routed into the base 1 through the connecting shaft 2 and the bracket 11, and then pass through the base 1 to connect to an external power supply, so as to make the appearance of the rotary display device neater and improve the consistency of the look and feel.

[0045] Furthermore, a plug 12 is provided on one side of the base 1 , and a socket 13 adapted to the plug 12 is provided on the other side of the base 1 . Both the plug 12 and the socket 13 are electrically connected to the mainboard 4 .

[0046] In this embodiment, the connection line between the plug 12 and the socket 13 is parallel to the axis of the connecting shaft 2. More than two revolving display devices can be arranged side by side when in use, and the plug 12 of one base 1 can be plugged into the socket 13 of the adjacent base 1, so that the mainboards 4 of the two revolving display devices are electrically connected, thereby synchronously displaying the time, such as the drum 5 of one revolving display device displays the time information in hours, and the drum 5 of the other revolving display device displays the time information in minutes, thereby providing more diverse choices for the use of the revolving display device and enhancing the fun of the revolving display device.

[0047] Furthermore, the motor 3 is a stepper motor 3, which is a precision motor 3. The rotation angle of the output shaft of the motor 3 can be accurately controlled by controlling the current through the mainboard 4, which is more suitable for use scenarios such as rotary wheel display devices that require high-precision stepping motion.

[0048] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
