[0022] Please see Figures 1-4 An embodiment of an anti-collision device for a movable sliding screen provided by this utility model:

[0023] The slide rail 1, controller 11, motor 12, threaded rod 13, slider 14, display screen 15, infrared transmitter 23, infrared receiver 26 and dual-head motor 29 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] A collision prevention device for a movable sliding screen includes: a sliding rail frame 1, a controller 11 mounted on the front of the sliding rail frame 1, a motor 12 mounted on the left side wall of the sliding rail frame 1, a threaded rod 13 movably mounted on the bottom surface of the sliding rail frame 1 via a bearing, a slider 14 slidably mounted on the bottom surface of the sliding rail frame 1, and a display screen 15 fixedly mounted on the bottom surface of the slider 14.

[0025] The left and right side walls of the display screen 15 are provided with anti-collision structures 2, each of which comprises a first fixed plate 21 fixedly installed at the upper end of the side wall of the display screen 15, a first angle iron 22 welded at the bottom edge of the first fixed plate 21, an infrared emitter 23 fixedly installed at the middle of the bottom surface of the first fixed plate 21, a second fixed plate 24 fixedly installed at the lower end of the side wall of the display screen 15, a second angle iron 25 welded at the top edge of the second fixed plate 24, an infrared receiver 26 fixedly installed at the middle of the top surface of the second fixed plate 24, a protective sleeve 27 attached to the side wall of the second fixed plate 24, a fixed block 28 fixedly installed on the side wall of the display screen 15, a double-head motor 29 fixedly installed at the inner side of the fixed block 28, and a flap 210 fixedly connected to the output end of the double-head motor 29, with a ring-shaped sealing gasket 211 attached to the bottom surface of the flap 210. When a person or an object approaches the display screen 15 during movement, the controller 11 sends a signal to the motor 12 to immediately stop the motor, thereby achieving collision detection and stopping functions of the display screen 15 during movement, greatly increasing the safety of the display screen 15, especially in applications such as shopping malls and factories where the display screen needs to be moved, thereby increasing the safety of the system and making the system more widely used.

[0026] Further, the output end of the motor 12 is fixedly connected with a threaded rod 13, the threaded rod 13 penetrates through the sliding block 14 and is threadedly connected with the sliding block 14, the motor 12 provides power for the rotation of the threaded rod 13, and the rotation of the threaded rod 13 can drive the sliding block 14 to move left and right on the bottom surface of the slide rail frame 1, so as to adjust the position of the display screen 15.

[0027] Further, the infrared emitter 23 is aligned with the infrared receiver 26, the infrared emitter 23 is adapted to the infrared receiver 26, and the infrared receiver 26 can receive the infrared signal emitted by the infrared emitter 23, so as to stop the movement of the display screen 15 when a person or an object contacts the display screen 15.

[0028] Further, the controller 11, the motor 12, the infrared emitter 23, the infrared receiver 26, and the double-head motor 29 are electrically connected, the contact between a person or an object and the display screen 15 blocks the transmission of the infrared signal, the infrared receiver 26 cannot receive the infrared signal of the infrared emitter 23, the controller 11 sends a stop instruction to the motor 12, the motor 12 stops working, and the controller 11 can control the start and stop of the double-head motor 29.

[0029] Further, the top surface of the protective sleeve 27 is higher than the top end of the infrared receiving device 26, the fixing block 28 is located on the upper side of the second fixing plate 24, the protective sleeve 27 provides support for the installation of the flap 210, so that the flap 210 can be fixed on the upper side of the infrared receiving device 26, so as to shield dust on the upper side, avoid the dust in the environment from floating to the infrared receiving device 26, and affect the sensitivity of the anti-collision structure 2.

[0030] Working principle: in use, the motor 12 is started by the controller 11, which drives the threaded rod 13 to rotate. The threaded rod 13 is in threaded connection with the sliding block 14, and the rotation of the threaded rod 13 drives the sliding block 14 to move at the bottom of the slide rail frame 1, thereby driving the display screen 15 to move left and right through the sliding block 14, so as to adjust the position of the display screen 15.

[0031] When the display screen 15 is moving, no one or object contacts the display screen 15, the infrared receiving device 26 normally receives the infrared signal. Once the infrared signal transmission is blocked by the contact between the person or object and the display screen 15, the infrared receiving device 26 cannot receive the infrared signal, the controller 11 sends a stop command to the motor 12, the motor 12 stops working, the person or object is separated from the display screen 15, the infrared receiving device 26 normally receives the infrared signal, and the motor 12 resumes work, and the display screen 15 continues to move.

[0032] The first angle iron 22 and the second angle iron 25 are respectively welded on the first fixing plate 21 and the second fixing plate 24, and one side wall of the first angle iron 22 and the second angle iron 25 is fixed on the display screen 15, which can provide support and fixation for the installation of the first fixing plate 21 and the second fixing plate 24 on the display screen 15, increase the rigidity of the connection between the first fixing plate 21 and the second fixing plate 24 and the display screen 15, and avoid deformation of the first fixing plate 21 and the second fixing plate 24 due to external force, which causes the infrared emitting device 23 and the infrared receiving device 26 to deviate and fail to align, thereby affecting the use of the anti-collision structure 2.

[0033] The protective sleeve 27 is bonded to the outer wall of the second fixing plate 24, which can avoid pedestrians from knocking the second fixing plate 24 and causing injury, ensuring the safety of the device, and providing protection for the infrared receiving device 26.

[0034] When the display screen 15 is fixed, the flap 210 covers the upper side of the protective sleeve 27, and the annular sealing gasket 211 is attached to the protective sleeve 27. The flap 210 can shield the infrared receiving device 26 from dust on the upper side, and avoid the dust in the environment from drifting onto the infrared receiving device 26, thereby affecting the sensitivity of the anti-collision structure 2. Meanwhile, before the display screen 15 is moved, the controller 11 can control the double-head motor 29 to start. The output end of the double-head motor 29 is fixedly connected with the flap 210. The operation of the double-head motor 29 drives the flap 210 to deflect on the fixed block 28, so that the flap 210 is moved away from the upper side of the infrared receiving device 26. The infrared receiving device 26 and the infrared emitting device 23 can be linked together, thereby providing safety protection for the movement of the display screen 15.

[0035] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can implement the present application according to the drawings and the above description. However, any equivalent changes, modifications and evolutions made by those skilled in the art within the scope of the technical scheme of the present application, using the disclosed technical content, are equivalent embodiments of the present application. Meanwhile, any equivalent changes, modifications and evolutions made according to the essential technology of the present application are still within the protection scope of the technical scheme of the present application.
