Description

Technical Field

[0001] This utility model relates to the field of display control technology, and in particular to a display screen hanging system. Background Technology

[0002] With the continuous advancement of technology, LED displays have stood out among numerous display devices due to their significant advantages such as high brightness, seamless splicing, and rich colors. They are gradually replacing traditional splicing screens and projection equipment and are widely used in various industries. In particular, the application of LED displays is becoming increasingly popular in sports stadiums and stage performances.

[0003] However, in stadiums and stage performances, LED displays often need to have lifting and synchronization functions to meet different performance needs and venue layout requirements. For example, in large-scale events such as concerts and opening ceremonies of sporting events, LED displays may need to be lifted and lowered above the stage, or even perform complex actions such as opening and closing in mid-air, to create more creative and impactful stage effects. The realization of these functions places extremely high demands on the safety and reliability of the equipment.

[0004] In existing technologies, in scenarios where LED displays are suspended from multiple points, it is often difficult to achieve precise synchronous operation of the multiple points, which can easily lead to misalignment of the LED displays during the lifting and lowering process, thus failing to meet actual needs.

[0005] Therefore, it is necessary to provide a display screen hanging system to solve the above-mentioned problems existing in the prior art. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a display screen hanging system to solve the technical problem that it is often difficult to achieve precise synchronous operation of multiple hanging points in scenarios where LED displays are hung from multiple hanging points.

[0007] To solve the above-mentioned technical problems, this utility model provides a display screen hanging system for suspending a display screen for lifting and lowering movements, comprising:

[0008] support;

[0009] Multiple sets of suspension assemblies are mounted on the bracket; each set of suspension assemblies includes a first drive component, a drum, a wire rope, and a first absolute encoder. The drive shaft of the first drive component is connected to one end of the drum; both ends of the wire rope are fixedly connected to both ends of the drum, and the middle of the wire rope forms a load end, which is connected to the top of the display screen; the first absolute encoder is located at the other end of the drum and is used to obtain the rotation angle of the drum.

[0010] The controller is communicatively connected to the first absolute encoder and the first drive unit, and is used to obtain the vertical position data of each load end based on the rotation angle of the drum obtained by the first absolute encoder, and to control the motion state of the first drive unit based on the obtained vertical position data of each load end.

[0011] The display screen hanging system provided by this utility model has the following beneficial effects:

[0012] By setting multiple sets of suspension components to simultaneously suspend the display screen, and with the first absolute encoder and first drive component of each set of suspension components communicating with the controller, the first absolute encoder located at the other end of the drum transmits the rotation angle of the drum to the controller. A vertical position of the load end is preset as a reference position. The controller obtains the vertical position data of each corresponding load end based on the obtained rotation angle of the drum, and calculates the height difference between the vertical position of the load end and the reference position based on the obtained vertical position data of each load end. Based on the calculated height difference, a control command is generated and sent to the first drive component that needs to be adjusted, thereby controlling the movement state of the first drive component. This allows the wire rope of each set of suspension components to be synchronously wound onto or released from the drum, enabling multiple suspension points to synchronously drive the display screen to move up and down, ensuring the safety and reliability of the display screen during the lifting process.

[0013] Furthermore, an incremental encoder is provided on the drive shaft of the first drive component to obtain the rotational speed information of the first drive component.

[0014] Furthermore, it also includes a frequency converter, which is communicatively connected to the incremental encoder and the first drive unit, and is used to adjust the motion state of the first drive unit according to the received speed information of the first drive unit.

[0015] Furthermore, the suspension assembly also includes a tension sensor, which is disposed at the load end of the wire rope and is used to acquire the tension value of the wire rope in real time.

[0016] Furthermore, the outer circumference of the drum is provided with evenly distributed spiral grooves for uniformly winding the wire rope onto the drum.

[0017] Furthermore, the suspension assembly also includes a fixed pulley, with the middle part of the wire rope sleeved on the fixed pulley and extending downward to form two pre-set V-shaped angles.

[0018] Furthermore, the preset included angle ranges from 0 to 3.5°.

[0019] Furthermore, it also includes a translation component, which includes a second drive member and a second absolute encoder. The second absolute encoder is disposed on the drive shaft of the second drive member and is used to acquire displacement data of the translation component moving in the horizontal direction.

[0020] Furthermore, the translation assembly also includes a transmission component, a mounting plate, and a pulley assembly. The drive shaft of the second drive component is connected to the transmission component, the transmission component is connected to the mounting plate, and the pulley assembly is disposed at the bottom of the mounting plate.

[0021] Furthermore, it also includes two guide rails, with the bottoms of the two pairs of translation components slidably disposed on the two guide rails, and the tops of the two pairs of translation components connected to both ends of the bracket respectively. Attached Figure Description

[0036] like Figures 1-8 As shown, an embodiment of this utility model provides a display screen hanging system for suspending and raising a display screen, comprising: a bracket 10, multiple sets of hanging components 20, and a controller 30. The bracket 10 supports the multiple sets of hanging components 20 and the controller 30. The multiple sets of hanging components 20 form multiple suspension points for suspending the display screen 70. The controller 30 controls the multiple sets of hanging components 20 to achieve synchronous raising and lowering movements.

[0037] Multiple sets of suspension assemblies 20 are mounted on the bracket 10. Each set of suspension assemblies 20 includes a first drive component 21, a drum 22, a wire rope 23, and a first absolute encoder 24. The drive shaft of the first drive component 21 is connected to one end of the drum 22. The two ends of the wire rope 23 are respectively fixedly connected to the two ends of the drum 22, and the middle part of the wire rope 23 forms a load end 231, which is connected to the top of the display screen 70. The first absolute encoder 24 is located at the other end of the drum 22 and is used to acquire the rotation angle of the drum 22. The controller 30 is communicatively connected to the first absolute encoder 24 and the first drive component 21, and is used to obtain the vertical position data of each load end 231 based on the rotation angle of the drum 22 acquired by the first absolute encoder 24, and control the movement state of the first drive component 21 based on the obtained vertical position data of each load end 231.

[0038] The first drive unit 21 of each suspension assembly 20 drives the drum 22 to rotate. The drum 22 drives the wire rope 23 to be wound synchronously from both sides of the drum 22, so that its load end 231 drives the display screen 70 to move upward. Alternatively, the first drive unit 21 of each suspension assembly 20 drives the drum 22 to rotate in the opposite direction, so that the drum 22 drives the wire rope 23 to be released synchronously from both sides of the drum 22, so that its load end 231 drives the display screen 70 to move downward. That is, multiple suspension assemblies 20 form multiple suspension points to simultaneously suspend the display screen 70, so that multiple suspension points of the display screen 70 can move up and down synchronously, ensuring the stability and reliability of the display screen 70 during the suspension process.

[0039] By setting multiple sets of suspension components 20 to simultaneously suspend the display screen 70, and the first absolute encoder 24 and the first drive component 21 of each set of suspension components 20 are communicatively connected to the controller 40, the first absolute encoder 24 set at the other end of the drum 22 transmits the rotation angle of the drum 22 it obtains to the controller 40, a vertical position of a load end 231 is preset as a reference position, the controller 40 obtains the vertical position data of each corresponding load end 231 according to the obtained rotation angle of the drum 22, and calculates the height difference between the load end 231 and the reference position according to the obtained vertical position data of each load end, generates a control command according to the calculated height difference, and sends the control command to the first drive component 21 that needs to be adjusted, thereby controlling the movement state of the first drive component 21, so that the wire rope 23 of each set of suspension components 20 can be synchronously wound on the drum 22 or released from the drum 22, so that multiple suspension points can synchronously drive the display screen 70 to move up and down, ensuring the safety and reliability of the display screen 70 during the lifting process.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, in some specific embodiments, four sets of suspension assemblies 20 are arranged on a bracket 10 to form four suspension points for the display screen 70. The first drive member 21 of the first set of suspension assemblies 20 is used as the main drive member, and the first drive members 21 of the second, third, and fourth sets of suspension assemblies 20 are used as slave drive members. The rotation angle of the drum 22 of the first set of suspension assemblies 20 is obtained by the first absolute encoder 24 of the first set of suspension assemblies 20, and the obtained rotation angle is sent to the controller 30. The controller 30 calculates the vertical position data of the load end 231 of the wire rope 23 of the first set of suspension assemblies 20 based on the received rotation angle, and uses this as a reference. Similarly, the controller 30 simultaneously calculates the vertical position data of the load end 231 of the wire rope 23 of the second, third, and fourth sets of suspension assemblies 20, and calculates the height difference between the vertical position of the load end 231 of the second, third, and fourth sets of suspension assemblies 20 and the vertical position of the load end 231 of the first set of suspension assemblies 20. The controller 30 controls the first drive component 21 of the second set of hanging components 20 based on the calculated vertical height difference between the load ends 231 of the second and first sets of hanging components 20, ensuring that the movement of the first drive components 21 of the second and first sets of hanging components 20 is synchronized. Similarly, the controller controls the first drive components 21 of the third and fourth sets of hanging components 20 to ensure that the corresponding suspension points of the second, third, and fourth sets of hanging components 20 and the first set of hanging components 20 are synchronized, thereby ensuring that the lifting and lowering movements of the display screen during the hanging process are synchronized and avoiding misalignment. It should be understood that the vertical position data of each load end 231 is calculated by using the obtained rotation angle of the drum 22, combined with the diameter of the drum 22 and the winding condition of the wire rope 23. This calculation can be performed with reference to existing technologies and will not be elaborated here. It should be noted that the number of hanging components 20 is determined according to the actual usage and is not specifically limited.

[0041] If the height difference between the vertical position of the load end 231 of the second, third, and fourth group of hanging components 20 and the vertical position of the load end 231 of the first group of hanging components 20 exceeds the set synchronization tolerance threshold, the controller 30 immediately adjusts the output frequency of the corresponding slave drive to dynamically change the rotation speed of the slave drive, ensuring synchronous control of multiple hanging points and causing the height difference to quickly approach zero. This process is performed in parallel for all slave drives to ensure height synchronization of multiple hanging points in the entire display screen hanging system. For example, the display screen 70 can be a folding display screen or an integrated display screen.

[0042] like Figure 1 and Figure 4As shown, in some embodiments of this utility model, an incremental encoder is provided on the drive shaft of the first drive member 21 to obtain the rotational speed information of the first drive member 21. By installing the incremental encoder on the drive shaft of the first drive member 21, the motion state information of the first drive member 21 can be monitored in real time, thereby obtaining the rotational speed information of the first drive member 21. Exemplarily, the first drive member 21 is a motor. It should be understood that an incremental encoder is a sensor that converts mechanical rotation into pulse signal output. It detects the angular displacement of the rotating shaft and outputs a pulse signal proportional to the rotation angle. These pulse signals can be collected and processed by the control system to achieve accurate measurement and control of rotational motion.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the display screen hanging system further includes a frequency converter 40. The frequency converter 40 is communicatively connected to the incremental encoder and the first drive component 21, and is used to adjust the motion state of the first drive component 21 according to the received speed information of the first drive component 21. Specifically, the incremental encoder transmits the acquired speed information of the first drive component 21 to the frequency converter 40 in the form of pulse signals. The frequency converter 40 adjusts the power supply frequency of the first drive component 21 according to the speed information of the first drive component 21, so that the actual speed of the first drive component 21 is close to the set speed. After the overall system reaches stability, the deviation between the actual speed of the first drive component 21 and the set speed will not exceed 0.02% of the set speed. In this embodiment, the incremental encoder set on the drive shaft of the first drive component 21 and the frequency converter 40 cooperate to form a closed-loop control, so that the static synchronization accuracy of the speed of each motor reaches 0.02%, ensuring the accuracy of the overall system.

[0044] Meanwhile, the inverter 40 is connected to the controller 30. If the vertical difference between the vertical position of the load end 231 of the second, third, and fourth suspension components 20 and the vertical position of the load end 231 of the first suspension component 20 calculated by the controller 30 exceeds the set synchronization tolerance threshold, a control command to adjust the speed of the first drive component 21 is generated and sent to the inverter 40. The inverter 40 adjusts the power supply frequency of the first drive component 21 according to the received control command until the height difference approaches zero, thereby ensuring that the multiple suspension points of the display screen 70 can be synchronized during the suspension process, and the display screen 70 can be stably raised and lowered.

[0045] like Figure 1 , Figure 3 and Figure 6As shown, in some embodiments of this utility model, the suspension assembly 20 further includes a tension sensor 25. The tension sensor 25 is disposed at the load end 231 of the wire rope 23 to acquire the tension value of the wire rope 23 in real time. By setting the tension sensor 25 at the load end 231 of the wire rope 23, i.e., the connection point between the wire rope 23 and the display screen 70, the tension value of the wire rope 23 during the process of the wire rope 23 driving the display screen 70 to rise and fall is obtained, ensuring the safety and stability of the wire rope 23 suspending the display screen 70. Furthermore, the tension sensor 25 is communicatively connected to the controller 30, transmitting the real-time acquired tension value of the wire rope 23 to the controller 30 to ensure data accuracy and synchronization. If the controller 30 receives a tension value of the wire rope 23 exceeding a preset value, it needs to automatically alarm and stop the system, thereby ensuring the stability and safety of the suspension system. Simultaneously, the load-bearing safety of each wire rope 23 must achieve a safety factor of 8:1 for any of the winding cables.

[0046] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the outer circumference of the drum 22 is provided with uniformly distributed spiral grooves for uniformly winding the wire rope 23 onto the drum 22. By designing uniformly distributed spiral grooves on the outer circumference of the drum 22, the wire rope 23 is placed in the spiral grooves, so that the wire rope 23 can be orderly wound in the spiral grooves or released from the drum during the winding or unwinding process.

[0047] like Figure 6 and Figure 7 As shown, in some embodiments of this utility model, the hanging assembly further includes a fixed pulley 26. The middle part of the wire rope 23 is sleeved on the fixed pulley 26 and extends downward to form two V-shaped preset angles. In this embodiment, a V-shaped double-sided rope exit method of the wire rope 23 is designed, and the rope exit angle is a V-shaped preset angle, which ensures that the wire rope 23 does not affect the hanging point space position of the display screen 70 when performing the winding and unwinding action, and also prevents the wire rope 23 from detaching from the spiral groove. Specifically, the middle part of the wire rope 23 is wound around the fixed pulley 26. When the load end 231 of the wire rope 23 is at the lowest point, the wire rope 23 on both sides extends downward simultaneously to form two V-shaped preset angles. Taking one side as an example, the angle formed between the first rope segment 232 and the second rope segment 233 of the wire rope 23 is a V-shaped preset angle, that is, the rope exit angle of the wire rope 23 is controlled to be a preset angle.

[0048] like Figure 6 and Figure 7As shown, in some embodiments of this utility model, the preset included angle ranges from 0 to 3.5°. Specifically, when the load end 231 of the wire rope 23 is at its lowest point, the V-shaped preset included angle between the first rope segment 232 and the second rope segment 233 of the wire rope 23 is 3.5°; when the load end 231 of the wire rope 23 is at its highest point, the V-shaped preset included angle between the first rope segment 232 and the second rope segment 233 of the wire rope 23 is 0°. At this time, the winding position of the wire rope 23 is close to the middle of the drum 22, thus controlling the exit angle of the wire rope 23 from 0° to 3.5°, thereby preventing the wire rope 23 from detaching from the spiral groove. Figure 1 , Figure 3 and Figure 8 As shown, in some embodiments of this utility model, the display screen hanging system further includes a translation component 50. The translation component 50 includes a second drive member 51 and a second absolute encoder. The second absolute encoder is disposed on the drive shaft of the second drive member 51 and is used to acquire displacement data of the translation component 50 moving in the horizontal direction. Further, both the second drive member 51 and the second absolute encoder are communicatively connected to the controller 30. The second absolute encoder transmits the acquired displacement data in the horizontal direction to the controller 30. The controller 30 controls the movement of the second drive member 51 based on the received displacement data, thereby achieving precise control of the movement of each translation component 50.

[0049] like Figure 1 , Figure 3 and Figure 8 As shown, in some embodiments of this utility model, the translation component 50 further includes a transmission component 52, a mounting plate 53, and a pulley assembly 54. The drive shaft of the second drive component 51 is connected to the transmission component 52, the transmission component 52 is connected to the mounting plate 53, and the pulley assembly 54 is disposed at the bottom of the mounting plate 53.

[0050] like Figure 3 and Figure 8 As shown, in some embodiments of this utility model, the display screen hanging system further includes two guide rails 60. The bottoms of two pairs of translation components 50 are slidably disposed on the two guide rails 60. The tops of the two pairs of translation components 50 are respectively connected to both ends of the bracket 10. Exemplarily, the second driving component 51 is a motor, and the transmission component 52 is a gear. A rack meshing with the gear is provided on the side of the guide rail 60. The motor drives the gear to rotate, and the gear moves horizontally along the rack of the guide rail 60 to drive the mounting plate 53 to move synchronously. The mounting plate 53 drives the pulley group 54 to move linearly in the horizontal direction along the track of the guide rail 60, thereby synchronously driving the bracket 10 to move linearly in the horizontal direction, realizing that the hanging component 20 hangs the display screen 70 and moves horizontally. In this embodiment, the number of translation components 50 corresponding to one bracket 10 is four sets, that is, two sets of translation components 50 are disposed at one end of the bracket 10, and the other two sets of translation components 50 are disposed at the other end of the bracket 10.

[0051] like Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments of this utility model, the display screen hanging system further includes a movable pulley 27. The steel wire rope 23, after passing over the fixed pulley 26, is sleeved in the movable pulley 27 on both sides to form a load end 231.

[0052] In summary, existing technologies often struggle to achieve precise synchronous operation of multiple LED displays suspended from multiple points. This invention provides a display screen suspension system that simultaneously suspends the display screen using multiple sets of suspension components. Each set of suspension components has a first absolute encoder and a first drive unit communicatively connected to a controller. The first absolute encoder, located at the other end of the roll, transmits the acquired rotation angle of the roll to the controller. A pre-set vertical position at the load end is used as a reference position. The controller obtains the vertical position data of each load end based on the acquired rotation angle of the roll, calculates the height difference between the vertical position of each load end and the reference position, generates a control command based on the calculated height difference, and sends the control command to the controller. The system adjusts the first drive component to control its movement, ensuring that the wire ropes of each suspension assembly are synchronously wound onto or released from the drum. This allows multiple suspension points to simultaneously drive the display screen in lifting and lowering motion, guaranteeing the safety and reliability of the display screen during the lifting process. Furthermore, the use of incremental encoders and frequency converters ensures that the static synchronization accuracy of the speeds of each drive component (motor) reaches 0.02%, guaranteeing the overall system accuracy. Simultaneously, the load-bearing safety of each wire rope is designed to have a safety factor of 8:1 for any winding cable. Moreover, a V-shaped double-sided rope exit method is designed, with a preset exit angle, ensuring that the wire rope's winding and releasing actions do not affect the spatial position of the display screen's suspension points, and also preventing the wire rope from detaching from the spiral groove. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
