Detailed Description
The present invention will be described in further detail with reference to examples, but embodiments of the present invention are not limited thereto.
Example 1:
referring to fig. 1, 2 and 3, a floatable laser television comprises a flexible screen 1 and a laser television projection device 2, wherein the flexible screen 1 is arranged near a wall 3 and comprises a flexible screen 11 and a magnetic suspension device 12 connected with the flexible screen 11; the laser television projection device 2 comprises a laser projection generating module 21 and a containing module 22 for containing the flexible screen 1, wherein the laser projection generating module 21 and the magnetic levitation device 12 generate magnetic fields with the same magnetism when being electrified so as to drive the flexible screen 1 to float.
When the flexible screen 1 is used for laser projection, the flexible screen 11 and the magnetic levitation device 12 are electrified, the flexible screen 11 is unfolded by controlling the tension of conductive materials in the flexible screen 11 through current, and meanwhile, the magnetic levitation device 12 and the laser projection generation module 21 generate a magnetic field with the same magnetism, so that the magnetic levitation device 12 is levitated, and the flexible screen 1 can be driven to levitate.
When the flexible screen 1 is used, the flexible screen 11 and the magnetic levitation device 12 are controlled to be weakened to be powered off by the flexible screen 1, and in the process, the flexible screen 11 is curled, and the magnetic levitation device 12 drives the flexible screen 11 to descend to the storage module 22.
The magnetic levitation device 12 comprises a rotor, a gravity sensor, a displacement sensor, a first controller and a rechargeable battery, wherein the rechargeable battery supplies power to the controller; the controller is used for controlling the energizing current of the first conductive coil of the rotor to enable the magnetic levitation device 12 to generate a magnetic field with the same magnetism as the laser television projection device 2.
A gravity sensor and a displacement sensor are arranged in the rotor. The rotor is internally provided with a sphere which can conduct electricity, and the sphere is divided into four areas, namely an upper area, a lower area, a left area and a right area, so that the current can be controlled in the areas. When the flexible screen is kept horizontal from side to side and vertical from top to bottom, the conductive spheres are suspended inside the rotor with the same current per partition and are spaced from the periphery of the rotor with the same distance. If a leftward shift of the flexible screen is detected by the sensor, the controller increases the current in the right zone of the sphere until the flexible screen remains balanced. If a rightward shift of the flexible screen is detected by the sensor, the opposite is true. If a forward deflection of the flexible screen is detected by the sensor, the controller increases the current in the lower section of the sphere until the flexible screen remains vertical up and down. If a rearward deflection of the flexible screen is detected by the sensor, the opposite is true. Therefore, the controller recognizes the levitation position of the flexible screen 11 and whether the screen is inclined according to the detection signals of the center sensor and the displacement sensor, and controls the center of gravity and balance of the entire flexible screen 1 by controlling the current of the first wire coil of the rotor, such as maintaining the balance of the flexible screen 11 when the first coil current is within a preset value a or a preset range, but tilting the flexible screen 11 forward when the current is greater than the preset value a or the preset range; when the current is less than the preset value a or the preset range. Thus, when the flexible screen 11 is tilted forward, the current can be controlled to decrease; conversely, the control current increases. The controller adjusts the balance according to the degree of positional deviation of the displacement sensor.
The rotor detects whether the screen surface of the flexible screen 1 is vertical or horizontal or not through the gravity sensor and the displacement sensor. The controller controls the center of gravity shift of the rotor and the position control of the flexible screen 1 to be curled to the screen vertical, left and right horizontal according to the detected result.
As shown in fig. 4, the rotor may be a cuboid, or may be a cube or a sphere. The rotor is made of permanent magnet materials and has good magnetism.
The laser projection generating module 21 comprises a second controller, and a second conductive coil, a laser generating unit, a charging unit and a power supply unit which are connected with the second controller, wherein the coil directions of the first conductive coil and the second conductive coil are the same, and when current passes through, the second conductive coil and the first conductive coil generate a magnetic field with the same magnetism when the current passes through; the charging unit charges the rechargeable battery in a wireless charging mode. The wireless charging mode is an electromagnetic induction mode or a resonance mode.
As shown in fig. 4 and 5, the laser projection generating module 21 is provided with a groove for placing the housing module 22. The storage module 22 is provided with a latch 23 fixed with the groove.
The magnetic levitation device 12 is positioned in the middle of the unfolded flexible screen 11. The magnetic levitation device 12 is positioned in the middle of the fully unfolded flexible screen 1 and is a cube or cuboid box.
The storage module 22 is located at the top end of the side surface of the laser projection generating module 21, which is close to the flexible screen 1 and is flush with the top horizontal position of the laser projection generating device, and the storage module 22 is made of soft materials, can stretch out and draw back, can wrap or semi-wrap the flexible screen 1, and is not easy to damage the flexible screen 1 when in transportation in a storage state.
Although the invention has been described herein with reference to the above-described illustrative embodiments thereof, the above-described embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited by the above-described embodiments, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the scope and spirit of the principles of this disclosure.
