The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0025] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-3As shown, a rotary display device includes a drum 1, a fixed base 2, a motor 3 and a main board 4. The drum 1 is an internal hollow structure with two ends through. The drum 1 encloses the fixed base 2 inside and is rotatably sleeved on the fixed base 2. The fixed base 2 is provided with a left connecting part 5 at a position corresponding to the opening of one end of the drum 1, and a right connecting part 6 is provided at a position corresponding to the opening of the other end of the drum 1. A plug 51 and a magnet block 52 are provided on the end of the left connecting part 5, and a socket 61 adapted to the plug 51 and a magnetic attraction part 62 adapted to the magnet block 52 are provided on the end of the right connecting part 6. The plug 51 and / or the right connecting part 6 pass through the opening corresponding to the drum 1 to the outside. The motor 3 and the main board 4 are both arranged on the fixed base 2. The main board 4 is electrically connected to the motor 3, the plug 51 and the socket 61 respectively. The motor 3 can drive the drum 1 to rotate.

[0028] Specifically, the above-mentioned ends refer to the ends of the corresponding components away from the fixed base 2. In actual use, the left connecting portion 5 and the right connecting portion 6 can be connected to the outside via a bracket or a hanging rope (for example, a bracket is vertically provided on the top of the base, and the bottom side of the left connecting portion 5 and / or the right connecting portion 6 is connected and fixed to the bracket), so that the drum 1 is suspended in the air to facilitate its rotation. The main board 4 can be connected to an external power source via an electric wire. Various time information can be recorded on the drum 1, such as a number representing "hour", a number representing "minute", a number representing "second", a number representing the year, a number representing the month, a number representing the day, and so on. In this way, the revolving display device has more information that can be displayed, including but not limited to time information. The drum 1 can also be used to display information such as temperature and humidity. Of course, to display information such as temperature and humidity, a sensor such as a thermometer or hygrometer needs to be provided on the fixed base 2. The motor 3 drives the drum 1 to rotate based on the feedback information of the thermometer and hygrometer. Of course, a page-turning structure can also be installed on the outside of the drum 1, so that the rotary display device becomes a rotary page-turning clock; a display frame for selecting time information can be added to the fixed seat 2, so that the user can refer to the time information moved to the display frame.

[0029] In one embodiment, the output shaft of the motor 3 may be provided with a rubber wheel, the side wall of the rubber wheel abuts against the arc-shaped inner wall of the drum 1. Since the friction of rubber is large, when the output shaft of the motor 3 rotates, the drum 1 can be driven to rotate by the rubber wheel (not shown in the drawings).

[0030] In this embodiment, the mainboard 4 can control the rotation of the motor 3 to drive the drum 1 to intermittently rotate a specific angle, thereby changing the time information located in the display frame to achieve the effect of running time. The user can connect several rotary display devices in series through the plug 51 and the socket 61 to electrically connect the mainboards 4 and synchronize data for operation. At the same time, the corresponding left connecting part 5 and the right connecting part 6 will be adsorbed and connected by the magnet and the magnetic attraction member 62, thereby improving the strength and stability of the connection, so that the user can combine a new display matrix for displaying information according to usage requirements. Taking the increase of display information as an example, one drum 1 can be used to display hours and the other drum 1 can be used to display minutes, thereby improving the flexibility of use of the rotary display device, providing more diverse options for the use of the rotary display device, and making the use of the rotary display device more interesting.

[0031] Furthermore, the left connecting part 5 and the right connecting part 6 are coaxial, the left end of the drum 1 is rotatably sleeved on the left connecting part 5, and the right end of the drum 1 is rotatably sleeved on the right connecting part 6, and the end parts of the left connecting part 5 and the right connecting part 6 both extend to the outside so as to connect a bracket or a suspension rope to make the drum 1 rotate in the air.

[0032] Furthermore, the left connecting part 5 and the right connecting part 6 are both rotatably connected to the drum 1 through bearings 7 to reduce the friction resistance encountered by the drum 1 during rotation, improve the rotation smoothness of the drum 1, reduce the driving power consumption of the motor 3, and further enhance the energy-saving effect.

[0033] Furthermore, a connecting block 53 is provided on the end of the left connecting part 5, and a connecting notch 63 adapted to the connecting block 53 is provided on the end of the right connecting part 6. When the plug 51 of one rotary display device is plugged into the socket 61 of another rotary display device, the connecting block 53 corresponding to the plug 51 will be stuck in the connecting notch 63 corresponding to the socket 61, thereby enhancing the connection strength between the corresponding left connecting part 5 and right connecting part 6.

[0034] Furthermore, there are at least two connecting blocks 53 and connecting notches 63, and the connecting blocks 53 are evenly distributed along the end edge of the left connecting part 5. The connecting notches 63 and the connecting blocks 53 are arranged in a one-to-one correspondence, so that the ends of the interconnected left connecting part 5 and the right connecting part 6 are subjected to more uniform force, thereby further improving the connection strength.

[0035] Furthermore, a sensing member 41 is provided on the main board 4 , and a triggering member 11 is correspondingly provided on the side wall of the drum 1 . Rotating the drum 1 can move the triggering member 11 closer to or farther from the sensing member 41 . When the triggering member 11 approaches the sensing member 41 , the sensing member 41 can be triggered.

[0036] Specifically, the drum 1 has an absolute position. When the drum 1 is at the absolute position, the triggering member 11 will trigger the sensing member 41 .

[0037] In one embodiment, the main board 4 is arranged at the end of the motor 3 away from the output shaft, the sensing member 41 is a mechanical switch, such as a micro switch, and the trigger member 11 is a protrusion, which is arranged on the end wall of the inner cavity of the drum 1 close to the main board 4. The drum 1 can be rotated to make the protrusion approach and trigger the mechanical switch (not shown in the drawings).

[0038] In one embodiment, the main board 4 is arranged at the end of the motor 3 away from the output shaft, the sensing member 41 is a light sensor, such as an optocoupler, and the trigger member 11 is an annular plate, which is coaxially arranged on the end wall of the inner cavity of the drum 1 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 1 and the notch moves 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).

[0039] In this embodiment, the main board 4 is arranged on one side of the motor 3, and the trigger member 11 is correspondingly arranged at the eccentric position of the drum 1 close to one end of the motor 3. Taking the drum 1 starting to rotate from the absolute position as an example, when the revolving display device is turned on and used, the main board 4 will control the motor 3 to drive the drum 1 to rotate, so that the drum 1 rotates to the absolute position (equivalent to finding the origin), and then the main board 4 controls the drum 1 to rotate so that the displayed time matches the real time. After that, the drum 1 rotates regularly under the drive of the motor 3, and whenever the drum 1 rotates to the absolute position, the trigger member 11 will trigger the sensor 41 to send an electrical signal, so the main board 4 can The number of rotations of the drum 1 is determined by the number of triggering times of the sensor 41. Every time the drum 1 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 1 to rotate 6 degrees every minute, and the drum 1 rotates one circle every 60 times. If the drum 1 has not reached the absolute position after rotating 60 times due to the error of the motor 3, it means that the drum 1 is rotating slowly. At this time, the mainboard 4 will control the motor 3 to drive the drum 1 to rotate to the absolute position to achieve the purpose of calibrating the displayed time. The same is true when the drum 1 rotates too fast, thereby avoiding inaccurate time and improving the user experience.

[0040] Furthermore, the induction element 41 is a magnetic induction element, and the trigger element 11 is a magnet.

[0041] Furthermore, the magnetic inductor is a Hall sensor.

[0042] Specifically, the sensing element 41 can be a magnetoresistive sensor or a Hall sensor. In this embodiment, a Hall sensor is preferred. The Hall sensor can preset a Hall voltage value, which is a trigger value. When the magnet rotates with the drum 1 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 closest, 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 1 by the number of times the Hall sensor trigger value is reached.

[0043] Furthermore, the output shaft of the motor 3 is parallel to the axis of the drum 1, and an internal tooth structure 12 is provided on the inner wall of the drum 1 in the circumferential direction. A gear 31 is sleeved on the output shaft of the motor 3, and the gear 31 is engaged with the internal tooth structure 12. The output shaft of the motor 3 can drive the gear 31 to rotate, and the gear 31 will drive the drum 1 to rotate around the axis of the left connecting part 5 and the right connecting part 6 through the internal tooth structure 12.

[0044] Furthermore, the motor 3 is a stepper motor 3, which is a precision motor 3. The current can be controlled by the mainboard 4 to accurately control the rotation angle of the output shaft of the motor 3. It is more suitable for use scenarios such as rotary display devices that require high-precision stepping motion.

[0045] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention 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 present invention more thorough and comprehensive.
