Example 1

According to an embodiment of the present invention, there is provided an embodiment of a rotation method of a display device, it being noted that the steps shown in the flowcharts of the drawings may be performed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

Fig. 1 is a flowchart of a rotation method of a display device according to an embodiment of the present invention, in this embodiment, taking the display device as an interactive smart device as an example, as shown in fig. 1, the method includes the following steps:

step S102, receiving a rotation instruction, wherein the rotation instruction is used for controlling the wall hanging frame to drive the display device to rotate.

The steps in this embodiment may be performed by a controller of the interactive smart device. Specifically, the rotation instruction is an instruction for controlling the display device to rotate, the controller is further connected with the rotation motor of the wall hanging frame, and after receiving the rotation instruction, the controller sends the rotation instruction to the rotation motor of the wall hanging frame.

The wall hanging frame can be a wall hanging frame fixed on a vertical wall or a wall hanging frame fixed on a standing bracket, in an alternative embodiment, the wall hanging frame comprises a bracket and a rotating shaft connected with the bracket, and the frame body can rotate according to the rotation of the rotating shaft, so that display equipment erected on the frame body can be driven to rotate.

Fig. 2a, 2b and 2c are schematic views showing a wall hanging rack for driving a display device to rotate according to the above embodiment of the present application, in this example, the wall hanging rack stands on the ground through a base, a cross-shaped rack body grips the display device, a circle at the cross is used for illustrating a rotation shaft, and the rotation in this embodiment refers to the rotation about the rotation shaft, and since the rack body grips the display device, the display device rotates along with the rotation of the rack body. As shown in connection with fig. 2a, 2b and 2c, if it is desired to rotate the horizontally disposed display device to a portrait disposition, the display device may be controlled to rotate counter-clockwise from the state of fig. 2a until the state of fig. 2c is reached.

The rotation plane of the wall hanging frame is a plane vertical to the rotating shaft, and in normal cases, when the rotating shaft is in the horizontal direction, the rotation of the wall hanging frame is performed on the vertical plane; when the rotating shaft is hinged with the base, if the direction of the rotating shaft is adjusted, the rotating plane of the wall hanging frame can also change.

In the above step, receiving the rotation instruction includes any one of: receiving a rotation instruction through a touch interface; or receives a rotation instruction through a rotation switch.

Specifically, the touch interface is an interface of the controller for receiving a touch signal returned by the touch device, taking the interactive intelligent panel as an example, and the touch screen of the interactive intelligent panel sends the received touch signal to the controller of the interactive intelligent panel through the touch interface.

In an alternative embodiment, taking the example of receiving the rotation instruction through the touch interface, the interactive intelligent tablet provides a rotation control function, after the user triggers the rotation control function, the interactive intelligent tablet displays the rotation control interface to prompt the user to fill in corresponding rotation information, the rotation information can include a rotation angle and/or a rotation direction, the user fills in the rotation information to a corresponding area, and the interactive intelligent tablet receives the rotation instruction.

Also taking the example of receiving a rotation instruction through the touch interface, the interactive intelligent tablet provides a rotation control function, and after the user triggers the rotation control function, the interactive intelligent tablet can provide multiple selectable rotation options for the user, for example: a clockwise (counter) clockwise rotation of 180 degrees, a clockwise (counter) clockwise rotation of 90 degrees, etc., and the user selects any item, namely, sends a rotation instruction to the controller.

In another alternative embodiment, and by receiving the rotation command through the rotary switch, the rotary switch may be a physical switch disposed on the interactive smart board, and the rotary switch may have a plurality of gear positions, each corresponding to a different rotation angle in the control circuit through a different resistance value. The user rotates the rotary switch, and then the interactive intelligent panel can be like sending the rotation instruction.

Step S104, judging whether the space where the display device is located allows the display rotation.

When the display device rotates, the space required by the display device is larger than the space for placing the display device, and in order to place the situations that the display device collides with an obstacle and the like possibly caused by directly driving the wall hanging frame to rotate, the steps judge whether the space in which the display device is positioned allows the display device to rotate or not.

When the display device rotates, if collision with the obstacle occurs, the space where the display device is determined not to allow the display device to rotate according to the rotation instruction, and if collision with the obstacle does not occur, the space where the display device is determined to allow the display device to rotate according to the rotation instruction.

In an alternative embodiment, an infrared range finder may be mounted on the display device, and the distance between the display device and the surrounding obstacle is measured according to the infrared range finder, and whether the display device is allowed to rotate in the space where the display device is located is determined according to the measurement result.

As an alternative embodiment, step S104 specifically includes:

In step S1041, a first distance between the rotation center and the obstacle in four directions in the space where the display device is located is obtained, where the four directions are directions corresponding to four sides of the display device.

Specifically, the rotation center is a rotation shaft, and the obstacle may be a wall of an indoor environment or the like. The first distance may be obtained by a distance sensor provided at an edge of the display device. The display device is typically rectangular with one direction for each side. Fig. 3 is a schematic diagram of acquiring a first distance according to embodiment 1 of the application, and in combination with fig. 3, data acquired by a distance sensor at the edge of the display device is A, B, E, F, and then the first distances can be obtained according to the size of the display device, where a+ C, B + C, E + G, F +h shown in the figure can be used as the four first distances.

In addition, the distance sensor may be disposed beside the rotation shaft of the wall hanging frame, so as to directly detect the first distance.

Step S1043, determining whether the display device collides with the obstacle when rotated according to the first distance.

The first distance is used to determine a size of a space in which the display device is located, and the display device can be allowed to rotate only when the space in which the display device is located is sufficiently large.

As an optional embodiment, step S1043, determining, according to the first distance, whether the space in which the display device is located allows the display device to rotate according to the rotation instruction, includes:

In step S10431, it is determined whether all of the four first distances are greater than the second distances from the rotation center to each corner of the display device.

Specifically, when the rotating shaft of the wall hanging frame corresponds to the center of the display device, the second distance between the rotating shaft and each corner of the display device is the same, that is, the second distance is D, which is shown in fig. 3 in combination with the general diagonal line of the display device.

In step S10433, if all of the four first distances are greater than the second distance, it is determined that the display device does not collide with the obstacle when rotated.

In step S10435, if any one of the first distances is less than or equal to the second distance, it is determined that the display device collides with an obstacle when rotated.

Specifically, the distance between the center of the display device and the four corners is greater than the distance between the rotation axis and any one of the sides, and when the display device rotates, the positions of the four corners of the display device are changed, so that the display device may collide with the obstacle, and when the corner of the display device moves to a position where the obstacle is closer to the rotation axis along with the rotation, the display device may collide with the obstacle, or may contact with the obstacle, in the case where any one of the first distances is less than or equal to the second distance. And when the first distance is larger than the second distance, the distance from the rotating shaft to the obstacle is larger than the distance from the rotating shaft to the angle of the display device, so that the display device does not collide or contact the obstacle when rotating to any angle.

In an alternative embodiment, as shown in connection with fig. 3, in the example of fig. 3, four first distances are a+ C, B + C, E +g and f+h, and the second distance is D, where a+c > D, B +c > D, E +g > D and f+h > D are satisfied, the four first distances are all greater than the second distance.

The above scheme gives the greatest requirement for space when the display device rotates, and the display device can rotate at any angle as long as the requirement is met. In some cases, however, the rotation device rotates through an angle of not more than 90 °, so that the above-mentioned space requirement is not required. As an alternative embodiment, step S1043, determining whether the display device collides with an obstacle when rotated according to the first distance may be further performed as follows:

Step S10437, determining the preparation space required to occupy when the display device rotates according to the rotation angle in the rotation instruction.

Specifically, the above-mentioned preparation space is the space reserved for the rotation of the display device. When the display device rotates according to the rotation instruction, the displacement track and the rotating shaft of each angle form a sector necessarily, and the sector area can be the reserved space.

In step S10439, it is determined whether the preparation space contains an obstacle according to the first distance.

In step S10441, in the case where the preliminary space includes an obstacle, it is determined that the display device collides with the obstacle when rotated.

In step S10443, in the case where the preliminary space does not include an obstacle, it is determined that the display device does not collide with the obstacle when rotated.

Specifically, if an obstacle appears in the reserved space, it is stated that the current space is insufficient to leave a sufficient reserved space for the rotation of the display device, so it is determined that the obstacle collides with when the display device rotates, and if an obstacle does not appear in the reserved space, it is stated that the current space can leave a reserved space for the rotation of the display device, so it is determined that the obstacle does not collide with when the display device rotates.

In step S1045, if it is not collided with an obstacle when the display device rotates, it is determined that the space in which the display device is located allows the display device to directly rotate.

In step S1047, if it collides with an obstacle when the display device rotates, it is determined that the space in which the display device is located does not allow the display device to rotate directly.

If the obstacle is not encountered when the display device rotates, it means that the current space is large enough, the display device can be directly rotated, and if the obstacle is likely to be encountered when the display device rotates, it means that the current space is small, and the display device cannot be directly rotated.

As an alternative embodiment, after determining that the space in which the display device is located does not allow the display device to directly rotate according to the rotation instruction if it collides with an obstacle when the display device rotates, step S104 further includes:

Step S1049, determining whether the space in which the display device is located allows the display device to rotate after the display device is adjusted up and down.

If the current space of the display device does not allow the display device to rotate directly, the space on one side may not meet the rotation requirement of the display device, so that it can be further determined whether the space can meet the rotation requirement after the display device is moved.

In an alternative embodiment, still as shown in connection with fig. 3, taking the example of insufficient space above (i.e. a+c < D) or insufficient space below (i.e. b+c < D) the display device may be controlled to descend in case of a+c < D or to ascend in case of b+c < D if a+b+2c > 2D.

In step S1051, if the adjusted space still allows the display device to rotate, a prompt message is returned to the display device, where the prompt message is used to indicate that the rotation instruction is not executed.

Specifically, if the adjusted space still does not allow the display device to rotate, it is indicated that the display device is difficult to execute the rotation instruction at the current position, so that a prompt message is sent.

In an alternative embodiment, taking an interactive smart tablet as an example, if the adjusted space still does not allow the display device to rotate, a buzzer may be sent out, or a prompt such as "the tablet cannot rotate at the current position" may be displayed on the display interface.

And step S1053, if the adjusted space allows the display device to rotate, controlling the display device to adjust up and down, and controlling the wall hanging frame to drive the display device to rotate according to the rotation instruction.

Specifically, the up-and-down adjustment may be achieved by a lifting motor.

Still in the embodiment of fig. 3, when the condition a+b+2c >2d is satisfied, it is explained that the adjusted space allows the display device to rotate, and thus the display device is lifted and then controlled to rotate.

It should be noted here that if the space is allowed to rotate by adjusting in other directions (for example, adjusting in the horizontal direction), the display device may be controlled to adjust in other directions.

How to adjust the display device up and down is described below. Taking the example of insufficient space above the display device (a+c < D), the display device may be controlled to decrease the height H1, h1=d-a-C, and taking the example of insufficient space below the display device (b+c < D), the display device may be controlled to increase the height H2, h2=d-B-C.

Through up-and-down adjustment, the space can meet the requirement of the display device for the space during rotation, so that the rotation instruction can be executed.

And S106, controlling the wall hanging frame to drive the display device to rotate according to the rotation instruction under the condition that the space where the display device is located allows the display device to rotate according to the rotation instruction.

Specifically, the rotation instruction may include rotation information such as a rotation angle and a rotation direction, and the wall hanging frame is controlled to drive the display device to rotate according to the rotation instruction, that is, the wall hanging frame is controlled to correspondingly control the rotation motor of the wall hanging frame according to the direction and the angle in the rotation instruction, so that the effect that the display device rotates according to the rotation instruction is achieved.

In an alternative embodiment, the controller of the display device, upon receiving the rotation command, converts the rotation command into an electrical signal for control with the rotation motor, which rotates according to the received electrical signal, thereby driving the rotation of the display device.

As an alternative embodiment, the rotation instruction includes a rotation angle, and in a case that the space where the display device is located allows the display device to rotate according to the rotation instruction, controlling the wall mount to drive the display device to rotate according to the rotation instruction includes: the rotating shaft of the control wall hanging frame rotates according to the rotation angle.

Specifically, the rotation angle may be an angle between one side of the display device and a straight line in a horizontal direction or a straight line in a vertical direction.

As can be seen from the above, the above embodiment of the present application receives a rotation instruction, where the rotation instruction is used to control the wall hanging rack to drive the display device to rotate; judging whether the space where the display device is located allows the display device to rotate or not; under the condition that the space where the display equipment is located allows the display equipment to rotate, the wall hanging frame is controlled to drive the display equipment to rotate according to the rotation instruction. According to the scheme, the wall hanging frame is automatically controlled to drive the display equipment to rotate through the mode of receiving the rotation instruction, manual participation is not needed, the technical problem that the display equipment can only rotate in a manual mode in the prior art, and the control of the equipment is inconvenient is solved, the space where the display equipment is located is judged by controlling the rotation process of the wall hanging frame, so that the situation that the display equipment possibly collides with an obstacle when rotating under the condition of insufficient space is avoided, the intelligent degree of the wall hanging frame is improved, and the user experience of a user using the wall hanging frame can be improved.

Example 2

According to an embodiment of the present application, there is also provided an embodiment of a rotation method of a display device, which is a more specific description of the rotation method of the display device in embodiment 1. Fig. 4 is a schematic diagram of a rotation method of a display device according to embodiment 2 of the present application, as shown in fig. 4, the method including:

And step S45, controlling the wall hanging frame to drive the display device to rotate according to the rotation instruction under the condition that the space where the display device is positioned allows the display device to rotate.

Step S47, controlling the display device to rotate the display interface.

After the display device rotates under the drive of the wall hanging frame, the display content of the display device may not match with the viewing angle of the user, for example, if the display device rotates from horizontal to vertical, the picture in the display device also rotates by 90 °, so that the user is inconvenient to view the display interface. The scheme controls the display interface to rotate along with the rotation of the display device, so that the aim that the display interface can accord with the viewing angle of a user no matter how the display device rotates is fulfilled.

In an alternative embodiment, whether to control the rotation of the display interface of the display device may be determined by comparing the rotation angle in the rotation instruction with a preset rotation angle beat. For example, the preset rotation angle is 45 °, and when the rotation angle in the rotation instruction is greater than 45 °, the display interface is adaptively rotated according to the rotated state of the display device.

Fig. 5 is a flowchart of an alternative rotation control of a display device according to embodiment 1 of the present application, and a rotation control method in the above embodiment is described below in connection with an example of fig. 5, in which the display device is an interactive smart tablet.

And S53, the main chip receives the rotation instruction and processes the rotation instruction.

The main chip is the controller of the interactive intelligent flat panel, and the controller processes the rotation instruction into control electric signals of the rotation motor and the lifting motor after receiving the rotation instruction.

S54, it is determined whether the up/down direction distance obstacle of the display device satisfies a first preset condition. If yes, the process proceeds to step S57, otherwise, the process proceeds to step S55.

This embodiment is exemplified by determining the up/down direction, and the left/right direction can be determined in practice. Still taking fig. 3 as an example, the first condition may be a+c > D, and b+c > D.

S55, it is determined whether the up/down direction distance obstacle of the display device satisfies a second preset condition. If yes, step S56 is entered, otherwise, a non-rotatable prompt message is displayed through the display interface in S51.

Specifically, the second preset condition is used to determine whether the display device is rotatable after moving up/down. Still referring to fig. 3, the second preset condition may be a+b+2c >2d, and a+c < D or b+c < D.

S56, the lifting motor controls the wall hanging frame to lift.

Still taking fig. 3 as an example, when the condition a+b+2c >2d is satisfied, the wall hanging frame is controlled to be lowered by the height h1=d-a-C when a+c < D, and the wall hanging frame is controlled to be raised by the height h2=d-B-C when b+c < D.

S57, controlling the wall hanging frame to rotate by the rotating motor. Specifically, the rotary motor executes a rotation instruction according to the received electrical signal.

S58, the display interface rotates according to the rotation of the display device.
