The display screen 1 is used for displaying, supplying power and controlling, the electric rotary hanging rack 2 is used for an actuating mechanism of electric rotary kinetic energy, and the fixing plate 3 can be used for fixing the display screen on a wall body to support the whole device.

Further, the whole television 1 can be used as a main body of the whole set of scheme, and as a front-end display device, a power supply is provided for the electric rotary hanging rack through a television main board, a corresponding control program is built in, and the operation of the rotary device 2 is controlled through real-time detection.

The whole operation thought is as follows: the TV mainboard provides 12v voltage for deciding the board module, decides board module output power to transmit commentaries on classics board module through the pivot module, the rotation of commentaries on classics board module drives and links firmly the complete machine rotation, decides board detection module simultaneously and can detect the running angle in real time, realizes that the horizontal of TV erects the screen accurate rotation. The concrete implementation is as follows: the television main board supplies power to the motor, the motor rotates to drive the rear gear box to rotate (the gear box is in worm and gear transmission, the rotating speed can be reduced, the torque can be improved), the output shaft end of the motor assembly is connected with the small chain wheel, the small chain wheel and the large chain wheel fixed on the rotating plate form primary chain transmission through a chain, the rotating plate is fixedly connected with the large chain wheel, the rotating plate and the large chain wheel synchronously rotate to realize the rotating action of the whole device, meanwhile, the die-casting rotating shaft and the pom gasket are arranged at the central positions of the rotating plate and the fixed plate, and the cushion block is arranged on the fixed plate, so that the coaxiality and the stability of the operation in the operation process are ensured. In the rotating process, a sensor on the fixed plate detects the magnets at 0 degree and 90 degrees on the rotating plate in real time, and if the rotating plate rotates in place, the device is immediately powered off; if the device is damaged and cannot be detected, the mechanical limit at 0-90 degrees on the rotating plate and the fixed plate can stop the device (the program locked rotor detection causes the device to be powered off), so that the use accuracy and the safety of the device are ensured.

Fig. 9 is a schematic top view of a rotating device according to an embodiment of the present disclosure. As shown in fig. 9, the rotating device includes: hall devices (9101, 9102), magnets (9001, 9002, 9003, 9004), and a rotating assembly 9400.

The rotating assembly 9400 includes a first surface (fig. 9 is a top view, where the first surface and the second surface may overlap in a top view, and the first surface is denoted as the first surface) for disposing the hall device, and a second surface (fig. 9 is a top view, where the first surface and the second surface may overlap in a top view, and the second surface is denoted as the second surface in the figure) for disposing the magnet, where the first surface and the second surface are connected in a concentric rotation manner.

The rotating assembly 9400 is used to rotate the tv. Illustratively, a central hole is formed in the middle of the rotating assembly, and a wire rod penetrates through the central hole, wherein the wire rod is connected to the screen end from the port plugging position, is routed to the wire outlet hole in the middle of the rotating mechanism along a gap between the display screen and the rotating mechanism, passes through the wire outlet hole, then sags, and extends out along the wire arranging groove of the rotating mechanism. In the process of rotating the television, the position of the television changes, wires from the wire outlet hole of the rotating mechanism to the television end rotate along with the television, and wires outside the wire outlet hole of the rotating mechanism keep static.

In one possible implementation, the second surface is a fixed surface and the first surface is a rotatable surface. For example, the second surface may be fixed to a wall or other supporting object, and the first surface may be fixedly connected to the screen end for driving the screen to rotate.

Under the condition that the first surface and the second surface rotate concentrically, the magnet and the Hall device have an induction point, and at the induction point, the state of the Hall device is used for identifying the position of equipment connected with the rotating assembly.

For example, under the condition that the first surface and the second surface rotate in a communication mode, the magnet and the hall device may coincide in the vertical direction, the hall device and the magnet can sense the hall device, the state of the hall device is changed, and the rotating position of the display screen can be reflected based on the state of the hall device.

In the embodiment of the application, the number and the setting positions of the Hall devices and the number and the setting positions of the magnets are related to the control mode required by the display screen in practical application.

In a possible implementation manner, if the display screen needs to be controlled to realize setting of two states, for example, the two states are a horizontal screen state or a vertical screen state, the state (for example, H or L) of one hall device can satisfy the identification of the two states, the number of the hall devices can be 1, and the number and the positions of the magnets can be set according to the rotation stop position of the display screen, so that when the hall devices and the magnets sense, the display screen can be controlled to stop.

In one possible implementation mode, the number of the Hall devices is multiple, and the number of the magnets is multiple; the plurality of Hall devices are arranged in the first surface in a non-overlapping mode; the plurality of magnets are arranged in the second surface without overlapping.

For example, if the number of the hall devices is N, the hall devices may be used to identify the state of the display screen within the power of 2N, and therefore, the specific number of the hall devices and the specific number of the magnets may be set according to actual requirements. Wherein, a plurality of hall device do not have the overlap in first face and set up, and a plurality of magnet do not have the overlap in the second face to can avoid because of overlapping the cross induction that leads to.

In a specific implementation manner, as shown in fig. 9, the number of the hall devices is two, and the two hall devices include a first hall device 9101 and a second hall device 9102; the number of the magnets is four, and the magnets include a first magnet 9001, a second magnet 9002, a third magnet 9003 and a fourth magnet 9004; the first magnet 9001 and the second magnet 9002 are disposed on a circumference of a first circle 9300 of the second face; the first magnet 9001 is positioned at a position of-90 degrees of a first circle, the second magnet 9002 is positioned at a position of 0 degree of the first circle, and the center of the first circle 9300 is a concentric rotary connection position of the first face and the second face; the third magnet 9003 and the fourth magnet 9004 are arranged on the circumference of a second circle 9301 of the second face; wherein the third magnet 9003 is located at 0 degree of the second circle 9301 and the fourth magnet 9004 is located at 90 degree of the first circle 9301; the first circle and the second circle are concentric circles with different radiuses; on the first face, the first face and the second face are concentrically and rotationally connected at a position that is a distance from the first hall device 9101 that is a radius of a first circle (or it can be understood that the first hall device 9101 is disposed on a circumference of the first face corresponding to the first circle); the concentric rotational connection of the first and second faces is located a distance from the second hall device 9102 on the first face that is a radius of the second circle (or, as can be appreciated, the second hall device 9102 is disposed on a circumference of the first face that corresponds to the second circle).

In this implementation, two magnets are placed on concentric circles of different radii, with the magnets fixed on one face of the rotating mechanism. The Hall device is placed on two concentric circles corresponding to the magnets and placed on the other side of the rotating mechanism, and the two planes move relatively when the Hall device rotates. The two hall devices (H IN1 and H IN2) corresponding to position can be as shown IN table 1 below:

TABLE 1

For the control process, the normal rotation control is divided into two types, one type is that the rotation is fixed by 90 degrees every time, and the control process is stopped when the state of the hall device changes, and the implementation process is as follows:

the remote controller selects forward rotation and reverse rotation, for example, the television rotates clockwise when the forward rotation is selected, the whole machine firstly confirms the current television state information according to the state of the Hall device (also called as Hall sensor), judges that the rotation action can be executed and then rotates, and when the Hall device signal jumps again at low level after the rotation, the rotation stops and simultaneously records the state of the Hall device. When the current state of the television reaches 90 degrees, if a clockwise rotation instruction is received again, the whole television can not be executed by judgment, and the television does not rotate.

The other one is that a final state of rotation can be selected, and the rotation is stopped after the final state is reached, and the implementation process is as follows:

when the box SOC outputs clockwise rotation, anticlockwise rotation or rotation degrees, the current position is judged firstly, then the state of the Hall sensor at the target position is judged, and when the state of the Hall sensor at the target position appears, the stop is carried out. For example, when a television is at a 90-degree position at present, the box SOC sends an instruction to rotate 180 degrees counterclockwise, the state of a Hall device corresponding to the 180-degree counterclockwise rotation is calculated to be L/H, then the rotation is started, when the rotation reaches 0 degree, an LL state appears, and when the L/H state appears, the rotation is stopped, and the rotation can be carried out beyond 90 degrees by the design mode.

In addition, with the structure shown in fig. 9, after the display device is turned on, the state of the hall device may be detected first, and if the state of the hall device is one corresponding output combination (at least one low level) of-90, 0, and 90, the television performs display content adjustment according to the actual state of the television. If the Hall device detects that the Hall devices corresponding to other positions output (both the Hall devices output high levels), the television firstly needs to rotate towards one direction so as to ensure that the output of the television is adjusted after the television reaches a fixed state.

To sum up, in the embodiment of the present application, a display device is provided, which includes a display screen and a rotating device, and the display screen can be driven to rotate based on the rotating device, so as to be capable of adapting to various program display requirements. Specifically, the rotating device may include a hall device, a magnet, a first surface for disposing the hall device, and a second surface for disposing the magnet; wherein the first surface and the second surface are connected in a concentric rotation mode; under the condition that the first surface and the second surface rotate concentrically, the magnet and the Hall device have an induction point, and at the induction point, the state of the Hall device is used for identifying the position of equipment connected with the rotating device. Therefore, the display equipment such as a television and the like can be driven to rotate based on the control of the rotating device so as to adapt to the display requirements of various programs.

An embodiment of the present application further provides a control method of a rotating apparatus, where the rotating apparatus includes any one of the rotating apparatuses described above, and as shown in fig. 10, the method includes:

s101: and receiving a rotation instruction.

In this embodiment of the application, the rotation instruction may be sent by using a remote controller, and the rotation instruction may include a forward rotation instruction, a reverse rotation instruction, or an instruction indicating a final rotation state, which is not specifically limited in this embodiment of the application.

S102: and reading the state of the Hall device in the rotating device.

In the embodiment of the present application, the current television status information may be firstly confirmed according to the status of the hall device (which may also be referred to as a hall sensor).

S103: and judging whether the state of the Hall device conflicts with the rotation instruction or not.

In the embodiment of the application, if the state of the hall device conflicts with the rotation instruction, the execution of the rotation instruction may cause a fault in the rotation, so that whether the state of the hall device conflicts with the rotation instruction is judged first, and the rotation is performed after the execution of the rotation action is judged.

S104: the state of the Hall device does not conflict with the rotation instruction, and the rotating device is controlled to rotate according to the rotation instruction.

S105: and the state of the Hall device conflicts with the rotation command, and the operation is finished.

and reading the state of the Hall device, and stopping the rotation of the rotating device when the state of the Hall device changes.

In the embodiment of the application, after rotation, when the state of the hall device is changed, for example, low level jump occurs, the rotation is stopped, and the state of the hall device is recorded. When the current state of the television reaches 90 degrees, if a clockwise rotation instruction is received again, the whole television can not be executed by judgment, and the television does not rotate.

calculating a target state of the Hall device corresponding to the rotation angle; when the state of the hall device is the target state, the rotation of the rotating means is stopped.

For example, when the rotation command includes the rotation degree, the current position is determined first, the state of the hall sensor at the target position is determined, and the hall sensor at the target position is stopped when the state occurs. For example, when a television is at a 90-degree position at present, a rotation instruction indicates that the television rotates 180 degrees counterclockwise, the state of a hall device corresponding to the 180-degree counterclockwise rotation is calculated to be L/H, then the rotation is started, when the rotation reaches 0 degree, an LL state appears, and when the L/H state appears, the rotation is stopped, and the rotation can be performed beyond 90 degrees.

In a possible implementation manner, the method further includes:

reading the state of the Hall device under the condition of receiving a starting instruction; and under the condition that the read state of the Hall device reflects that the rotating device is at other angles, adjusting the rotating device to be-90 degrees, 0 degrees or 90 degrees.

In the embodiment of the application, after the display device is started, the state of the Hall device can be detected firstly, and if the state of the Hall device is one corresponding output combination of-90, 0 and 90, the television adjusts the display content according to the actual state of the television. If the Hall device detects that the Hall device corresponding to other positions outputs, the television firstly needs to rotate towards one direction to ensure that the output of the television is adjusted after reaching a fixed state.
