The control component is used to control the movement state of the lifting component and the horizontal moving component to adjust the state of the flexible screen 2.

[0042] The working principle and beneficial effects of the above technical solution are as follows: The base 1 is used to accommodate and install the flexible screen 2, the lifting component, the horizontal moving component, and the control component. The flexible screen 2 is vertically installed in the base 1. The lifting component is used to control the lifting height of the flexible screen 2. The horizontal moving component is used to control the size of the flexible screen 2 in the base 1 during the lifting process. The control component is used to control the movement of the lifting component and the horizontal moving component to drive the movement of the flexible screen 2. In use, the lifting component and the horizontal moving component are activated by the control component respectively. The coordinated movement of the lifting component and the horizontal moving component ensures that the flexible screen 2 rises or falls normally.

[0043] This invention uses a lifting component and a horizontal moving component to jointly adjust the motion state of a flexible screen. The movement mode is intelligently determined by the program instructions of the control components, and the movement of the lifting and horizontal moving components is automatically controlled to achieve intelligent adjustment of the flexible screen's state. The structure is simple, the size and state of the flexible screen are easily adjusted, and the control precision is high. It can accurately adjust the flexible screen's state according to the usage environment, has a wide range of applications, and is easy to use. The lifting and horizontal moving components provide high support stability, and the state of the flexible screen is not easily changed after adjustment, thus improving the lifespan of the flexible screen, enhancing safety, and improving the user experience.

[0044] In one embodiment, the horizontal movement component includes: a second motor 3 and a motion slider 4.

[0045] A second motor 3 is provided on the side of the base 1 away from the flexible screen 2, and a motion slider 4 is provided on the side of the base 1 close to the flexible screen 2.

The bottom end of the flexible screen 2 passes around the roller 7 and is connected to the motion slider 4.

[0046] The lifting assembly includes: a first motor 8 and a screen slider 9.

[0047] A screen fixing plate 10 is provided on the upper side wall of the flexible screen 2 near the base 1. A screen slider 9 is provided on the screen fixing plate 10. A housing 11 is provided at the top of the base 1. A first motor 8 is provided on the housing 11. One end of the first screw 12 is connected to the output end of the first motor 8, and the other end is threadedly connected to the screen slider 9. A first linear guide rail 13 is provided on both sides of the first screw 12. One end of the first linear guide rail 13 is slidably connected to the screen slider 9, and the other end is connected to the housing 11 through the support 14.

[0048] The working principle and beneficial effects of the above technical solution are as follows: When it is necessary to adjust the flexible screen 2 to rise, the first motor 8 and the second motor 3 are started. The first motor 8 rotates forward, driving the first screw 12 to rotate forward. Through the threaded transmission between the first screw 12 and the screen slider 9, the screen slider 9 is driven to move upward along the first linear guide rail 13, thus driving the flexible screen 2 to move upward along the first linear guide rail 13. At the same time, the second motor 3 runs in reverse, driving the second screw 5 to run in reverse. Through the threaded transmission between the second screw 5 and the moving slider 4, the moving slider 4 is driven to move along the second linear guide rail 6 in a direction away from the second motor 3, so as to keep the screen rising normally. When it is necessary to adjust the flexible screen 2 to retract, the first motor 8 and the second motor 3 are started in reverse, so that the second motor 3 rotates forward, driving the flexible screen 2 to move inward along the second linear guide rail 6. At the same time, the first motor 8 runs in reverse, driving the screen slider 9 to move downward along the first linear guide rail 13, so as to keep the screen retracting normally. The movement of the flexible screen 2 is stable and the height adjustment is convenient.

[0049] In one embodiment, such as Figure 5-6 As shown, the control components include: control box 15 and controller 16.

[0050] A control box 15 is provided inside the base 1. The control box 15 is provided with a controller 16, a wireless communication component 17 and a processor 18. A detection component 19 is provided inside the base 1. The processor 18 is electrically connected to the controller 16, the wireless communication component 17 and the detection component 19 respectively.

[0051] Detection component 19 includes: height sensor 20 and angle sensor 21.

[0052] The flexible screen 2 is equipped with a height sensor 20 and an angle sensor 21, and the processor 18 is electrically connected to the height sensor 20 and the angle sensor 21 respectively.

[0053] It also includes a remote control 27, which has a wireless transceiver component 28 that is wirelessly connected to the wireless communication component 17. The remote control 27 is equipped with a display panel 29 and a control panel 30.

[0054] The working principle and beneficial effects of the above technical solution are as follows: The control box 15 is used to install components such as the controller 16, the wireless communication component 17, and the processor 18. The controller 16 is used to control the start, stop, forward and reverse rotation of the first motor 8 and the second motor 3, thereby controlling the rise and retraction of the flexible screen 2. The wireless communication component 17 is used for wireless connection to the wireless communication component 17 in the remote controller 27, which allows the staff to input control commands through the display panel 29 and control panel 30 on the remote controller 27 to control the rise and retraction of the flexible screen 2. The height sensor 20 in the detection component 19 is used to detect the rising height of the flexible screen 2, and the angle sensor 21 is used to detect the tilt angle of the flexible screen 2 during the rising and falling process, ensuring the smooth movement of the flexible screen 2.

[0055] In one embodiment, a protective frame 22 is provided on the upper frame of the flexible screen 2, and a protective cover 23 is provided on the side wall of the protective frame 22 near the first motor 8, and the screen slider 9 is disposed inside the protective cover 23.

[0056] The working principle and beneficial effects of the above technical solution are as follows: the protective frame 22 facilitates the detachable installation of the protective cover 23, and the protective cover 23 is used to protect the lifting components and ensure the normal lifting of the flexible screen 2.

[0057] In one embodiment, a 0.1mm thick steel plate 24 is provided on the side wall of the lower part of the flexible screen 2 near the roller 7. Four rubber hinges 25 are provided on the steel plate 24 at intervals. The bottom ends of the steel plate 24 and the rubber hinges 25 pass around the roller 7, and the steel plate 24 is connected to the moving slider 4. Five pulley bearings 26 are provided on the roller 7 at intervals. The steel plate 24 passes around the pulley bearings 26 and is connected to the pulley bearings 26.

[0058] The working principle and beneficial effects of the above technical solution are as follows: the flexible screen 2 and the moving slider 4 are connected by a 0.1mm thick steel plate 24. The steel plate 24 moves around the pulley bearing 26 and bears the tension and thrust required for the rotation of the flexible screen 2, preventing damage to the flexible screen 2; the flexible screen 2 and the rubber hinge 25 are bonded together with adhesive. The rubber hinge 25 moves around the roller 7 and adopts a track-type structure to eliminate deformation caused by turning; under the running state of the first motor 8 and the second motor 3, the flexible screen 2 turns around the bearing center through the pulley bearing 26 at the turning point, realizing the roller design of the flexible screen 2.

[0059] In one embodiment, a flexible sleeve 31 is also included, with the flexible sleeve 31 provided at the top of the base 1, and the flexible screen 2 can extend and retract within the flexible sleeve 31.

[0060] The working principle and beneficial effects of the above technical solution are as follows: The flexible sleeve 31 is used to protect the flexible screen 2, lifting component, horizontal movement component and control component inside the base 1, to prevent the above components from being damaged by external influences, and to improve the service life of the system.

[0061] In one embodiment, such as Figure 7 As shown, a lubrication assembly is installed inside the base 1. The lubrication assembly includes: a third motor 32, a transmission rod 33, a first slider 34, and a guide rod 35.

[0062] A vertical first guide groove 36 is provided on the side wall of the motion slider 4 near the second motor 3. A vertical guide rod 35 is provided in the first guide groove 36. A first slider 34 is slidably mounted on the guide rod 35. A first spring 37 is sleeved on the upper part of the guide rod 35, and a second spring 38 is sleeved on the lower part of the guide rod 35. One end of the first spring 37 is connected to the first slider 34, and the other end is connected to the inner wall of the top of the first guide groove 36. One end of the second spring 38 is connected to the first slider 34, and the other end is connected to the inner wall of the bottom of the first guide groove 36. A third motor 32 is provided on the first slider 34. The output end of the third motor 32 is connected to one end of the transmission rod 33. The transmission rod 33 is parallel to the second screw 5.

[0063] The other end of the transmission rod 33 passes through the axis of the frustum 39 and is connected to the circular plate 40. The transmission rod 33 is fixedly connected to the frustum 39. A cavity 41 is provided inside the frustum 39. The transmission rod 33 passes through the axis of the cavity 41. A protrusion 42 is provided on one side wall of the transmission rod 33 located inside the cavity 41. Several fan blades 43 are spaced apart on the outer circumference of the circular plate 40. A liquid storage cavity 44 is provided on the outer circumference of the frustum 39. Several infusion pipes 45 connected to the liquid storage cavity 44 are spaced apart on the outer circumference of the frustum 39. The other end of the infusion pipe 45 is connected to a nozzle 46. A drive pump 47 is provided on the infusion pipe 45. Several bristles 48 are evenly distributed on the outer circumference of the frustum 39.

[0064] The working principle and beneficial effects of the above technical solution are as follows: After the control system has been used for a period of time, the drive pump 47 is started. The drive pump 47 pumps the lubricating coolant in the storage chamber 44 to the nozzle 46 through the delivery pipe 45 to spray it out, which lubricates and cools the horizontal moving component, roller 7, and pulley bearing 26 in the base 1, reducing the wear caused by the transmission of the horizontal moving component, roller 7, and pulley bearing 26, and improving the service life of the control system; the third motor 32 is started, which drives the transmission rod 33 to rotate, which in turn drives the protrusion 42 and the frustum 39 to rotate. The rotation of the protrusion 42 causes the transmission rod 33 to move up and down along the guide rod 35, which in turn drives the third motor 32 to move up and down along the guide rod 35, which in turn drives the first slider 34 to move back and forth on the guide rod 35, so that the first spring 37 and the second spring 38 are alternately compressed or stretched. Through the superposition of the motion, the transmission rod 33 rotates while moving along the guide rod. The guide rod 35 moves up and down, causing the truncated cone 39, circular plate 40, fan blade 43, and nozzle 46 to rotate and move up and down along the guide rod 35, increasing the spray range of the nozzle 46 and improving the lubrication efficiency of the lubricating coolant. The rotating fan blade 43 blows air, further increasing the spray range of the lubricating coolant and ensuring sufficient lubrication and maintenance of the internal mechanism of the base 1. At the same time, the fan blade 43 blows air to cool down the internal mechanism of the base 1, improving the heat dissipation efficiency of the internal mechanism of the base 1 and extending the service life of the internal mechanism of the base 1. The first spring 37 and the second spring 38 act as a buffer to reduce the impact caused by the vibration of the truncated cone 39. The brush bristles 48 sweep the sprayed liquid to prevent liquid accumulation and improve liquid utilization. The lubrication component is installed on the moving slider 4. After the second motor 3 is started, the lubrication component moves with the moving slider 4 to achieve spray lubrication of the covered area and ensure comprehensive lubrication and maintenance.

[0065] In some implementations, this application embodiment also includes a support rod 49, which is vertically disposed within the base 1 and slidably disposed on the inner wall of the bottom end of the base 1. The support rod 49 is located between the frustum 39 and the circular plate 40. A second guide groove 50 extending along the axis is provided on the support rod 49. A second slider 51 is slidably disposed within the second guide groove 50. One end of a third spring 52 is connected to the top end of the second slider 51, and the other end is connected to the inner wall of the top end of the second guide groove 50. One end of a fourth spring 53 is connected to the bottom end of the second slider 51, and the other end is connected to the inner wall of the bottom end of the second guide groove 50. A transmission rod 33 passes through the axis of the second slider 51 and is rotatably connected to the second slider 51.

[0066] The working principle and beneficial effects of the above technical solution are as follows: The support rod 49 is slidably set on the inner wall of the bottom end of the base 1. The support rod 49 is used to support the transmission rod 33. When the transmission rod 33 moves up and down along the guide rod 35, it drives the second slider 51 to move up and down in the second guide groove 50, which drives the third spring 52 and the fourth spring 53 to alternately compress or stretch. The third spring 52 and the fourth spring 53 play a buffering role, further reducing the impact generated by the vibration of the frustum 39. This avoids the transmission rod 33 from being damaged due to excessive vibration amplitude when the protrusion 42 drives the transmission rod 33 to rotate while moving up and down along the guide rod 35. At the same time, it avoids the fan blade 43 from colliding with the base 1 due to excessive vibration amplitude, thus improving the service life of the lubrication components.

[0067] In one embodiment, such as Figure 8-9 As shown, a heat dissipation assembly is installed inside the base 1. The heat dissipation assembly includes: a fourth motor 65, a crank 66, a sleeve 54, and a stop bar 55.

[0068] A heat dissipation vent 56 is provided on one side wall of the base 1. An annular filter screen 57 is provided inside the heat dissipation vent 56. A pentagonal prism 58 is provided on one side inner wall of the base 1. A sleeve 54 is fitted on the pentagonal prism 58. A sleeve tube 59 is provided on the outer circumferential wall of the sleeve 54 and is perpendicularly connected to it. A moving block 60 is slidably arranged inside the sleeve tube 59. A fifth spring 61 is provided inside the sleeve tube 59. One end of the fifth spring 61 is connected to one end of the moving block 60, and the other end is connected to the inner wall of the sleeve tube 59. The other end of the moving block 60 extends into the sleeve 54 and abuts against the pentagonal prism 58.

[0069] A vertical fixing rod 62 is provided on the inner wall of the bottom end of the base 1. A fourth motor 65 is provided at the top of the fixing rod 62. The output end of the fourth motor 65 faces the heat dissipation port 56 and is connected to one end of the crank 66. A stop bar 55 is provided at the other end of the crank 66. The other end of the stop bar 55 is located on one side of the sleeve 59. A wind plate 63 is provided on the other side wall of the crank 66. A brush 64 is provided on the side wall of the sleeve 59 near the heat dissipation port 56. The brush 64 is in contact with the annular filter screen 57.

[0070] The working principle and beneficial effects of the above technical solution are as follows: the heat dissipation vent 56 is used to dissipate the heat generated by the operation of the internal mechanism of the base 1; the annular filter screen 57 is used to prevent the internal mechanism of the base 1 from being contaminated by dust; the annular filter screen 57 will be clogged by dust after a period of use; the fourth motor 65 is started, driving the crank 66 to rotate, which in turn drives the stop rod 55 to rotate around the output shaft of the fourth motor 65; the stop rod 55 pushes the sleeve 59 and the sleeve 54 to rotate around the output shaft of the fourth motor 65; since the moving block 60 abuts against the pentagonal prism 58, during the rotation of the sleeve 59 around the pentagonal prism 58, the moving block 60 moves along the side wall of the pentagonal prism 58; the moving block 60 reciprocates within the sleeve 59, causing the fifth spring 61 to compress or recover, causing the moving block 60 to move from one side to the adjacent side. During the process, the sleeve 59 swings, thus driving the brush 64 to rotate around the pentagonal prism 58 while intermittently swinging. The brush 64 intermittently scans and cleans the annular filter 57, sweeping away the dust accumulated on the annular filter 57, keeping the annular filter 57 unobstructed, and improving the heat dissipation efficiency of the heat dissipation port 56. The intermittent swing of the sleeve 59 collides with the stop bar 55, shaking off the dust adhering to the brush 64, keeping the brush 64 clean, and improving the cleaning efficiency and quality of the brush 64. The crank 66 drives the fan plate 63 to rotate around the output shaft of the fourth motor 65. The fan plate 63 blows air to cool the fourth motor 65, improving the heat dissipation efficiency of the fourth motor 65 and extending the service life of the fourth motor 65.

When it is necessary to adjust the state of the flexible screen 2, the target parameters are input through the remote control 27, and the current state of the flexible screen 2 is detected by the detection component 19 to determine whether to control the flexible screen 2 to rise or fall.

[0073] S2. The control component obtains a control command based on the detection result of the detection component 19. The control component starts the drive unit of the lifting component and the horizontal moving component. The lifting component and the horizontal moving component move, driving the flexible screen 2 to move.

[0074] S3. After the lifting component and the horizontal moving component move the flexible screen 2 to the desired position, the control component shuts down the drive unit of the lifting component and the horizontal moving component, the lifting component and the horizontal moving component stop moving, and the flexible screen 2 no longer moves.

[0075] The working principle and beneficial effects of the above technical solution are as follows: When it is necessary to adjust the state of the flexible screen 2, the target parameters to be adjusted are input to the control component through the remote controller 27. The control component controls the detection component 19 to detect the current state of the flexible screen 2 and determine whether the flexible screen 2 needs to rise or fall to reach the target. After obtaining the control command based on the detection result of the detection component 19, the controller 16 starts the first motor 8 and the second motor 3, so that the lifting component and the horizontal moving component enter the running state and drive the flexible screen 2 to start moving. When the flexible screen 2 moves to the target position, the control component automatically shuts off the first motor 8 and the second motor 3, so that the lifting component and the horizontal moving component stop moving and the flexible screen 2 stops moving. The operation is convenient, the degree of intelligence is high, and the control is precise.
