The width of the cable 400 is the same as the width of the wheel axle 243 and the width of the guide wheel groove, so that the cable 400 can be ensured to be tightly wound on the wheel axle 243, vertically enter between the guide wheel 251 and the auxiliary wheel 252, and pass through the housing 100 downwards along the guide wheel 251.
In the present invention, the exhibit 300 is preferably a ball lamp, and the internal structure and the operation principle of the suspension display device 10 are specifically described below by taking the ball lamp as an example:
the four-core cable enters the inside of the casing 100 through the wire inlet hole 113, is connected to the first circuit board 270, and is connected with the motion control mechanism 230 through the first circuit board 270, so as to realize power supply and control signal input to the motion control mechanism 230; the angle sensor 261 is connected with the first circuit board 270 through a signal line so as to be connected with the motion control mechanism 230 through the first circuit board 270 to realize angle signal input; meanwhile, the motion control mechanism 230 converts the power signal and the light control signal into a form suitable for the cable 400 through the first circuit board 270, and transmits the power signal and the light control signal to the ball lamp through the wire 245 connecting the first circuit board 270 and the second circuit board 244, and because the cable 400 is connected with the second circuit board 244, the power signal and the light control signal can be transmitted to the ball lamp, so that the lighting of the ball lamp and the light conversion are realized. It can be seen that the second circuit board 244 serves as a relay. The motion control mechanism 230 is internally provided with a driver 232, a motor 231 and an encoder 233 which are connected, so that the motor 231 is controlled to rotate and the encoder 233 is controlled to count and position, and then the speed reducer 220 connected with the motor 231 drives the wire winding wheel disc 241 to rotate, and the up-and-down motion control of the cable 400 can be realized.
When the cable connector works, the movement 200 and the cable 400 are assembled according to the installation mode, and the electric wiring inside the movement 200 is completed; then, the shell 100 is installed, and the four-core cable is reserved outside the shell 100 through the wire inlet hole 113; then the outer shell 100 is fixedly installed on the truss 20 through the installation part on the outer shell 100; finally, the work of installing a single hanging display 10 is completed by installing display 300 at the end of cable 400.
Furthermore, the hanging display devices 10 with required number are hung on the interface controller in a daisy chain manner through the reserved four-core cable, the interface controller is communicated with the user upper computer (mobile terminals such as mobile phones and pads or a PC) through a network, control software is installed on the user upper computer, and the motion control of the hanging display system can be realized through simple interface operation.
If the suspension display system needs to be made to present a 3D dynamic model, each suspension display device 10 needs to be controlled in motion, and the display 300 needs to be controlled in light conversion. The user sends a control command, the control command is transmitted to the suspension display device 10 through the network and the interface controller, the control command enters the movement 200 through the four-core cable, the movement control mechanism 230 serves as a controller of the single suspension display device 10, the movement control command is distributed to the motor 231 to be executed after the user command is received, the light control command is distributed to the ball lamp, and the sensor signal is also transmitted to the movement control mechanism 230 through the first circuit board 270.
The working process of the hanging display system is as follows: the motor 231 executes movement after receiving the control signal, the motor 231 rotates, and the wire winding wheel disc 241 rotates according to the instruction under the action of the speed reducer 220, so that the cable 400 drives the exhibit 300 to move up and down according to the control instruction of the user. In this process, the motion control mechanism 230 receives the angle signal of the angle sensor, converts the angle signal into the length of the cable 400, and then determines the current position of the dome lamp according to the initial position data of the dome lamp, thereby realizing positioning. The light power and the light control signal are converted into the power and the light control signal suitable for the exhibit 300 (the ball lamp) through the first circuit board 270, and then transmitted to the second circuit board 244 through the conducting wire 245, and are transferred to the cable 400 through the second circuit board 244, and the conducting wire in the cable 400 transmits the power and the light control signal to the ball lamp, so that the power supply and the communication of the ball lamp are realized.
When the motor 231 rotates, the speed reducer 220 drives the winding wheel disc 241 to rotate, and the speed reducer 220 is used for reducing the rotating speed and increasing the torque, so that the rotating speed of the motor 231 can be matched with the rotating speed of the winding wheel disc 241 through the speed reducer 220, and the purpose of driving a large load with small power is achieved.
The rotation of the reel 241 causes the cable 400 to wind up and unwind on the reel 241, which in turn causes the display 300 to move up and down. Due to the structural arrangement of the movement 200 and the cable 400, when the cable 400 is rolled up, a circle of the cable is tightly attached, when the cable 400 is unfolded, the cable is tightened and cannot be deformed, and when the cable is repeatedly rolled up and unfolded for a plurality of times, the cable cannot be wound, so that the stable and reliable operation of the suspension display system is ensured.
In summary, the invention simplifies the structure of the movement 200 and improves the structure of the cable 400, so that the suspension display device 10 has large load and small volume, is more convenient to assemble, install and maintain, and has higher stability and reliability; the angle rotated by the angle sensor 261 is converted into the corresponding length of the movement of the cable 400, namely the descending height of the cable 400, so that the exhibit 300 is accurately positioned; the flat wide cable is arranged and the steel wire is arranged in the flat wide cable, so that the strength of the cable 400 is increased, the cable is not easy to deform, and the service life of the hanging display device 10 can be effectively prolonged; the wide cable is arranged to move more smoothly up and down and in the winding process, and winding cannot occur, so that the motor 231 is prevented from being locked. In addition, the display 300 moves up and down under the control of the computer to realize the three-dimensional figure change, and the 3D dynamic modeling of the brilliant color is presented by matching with the light effect.
