[0054] The LED display screen is a kind of flat panel display, which is composed of a plurality of small LED module panels, and is used to display text, images, videos and various information. The LED display screen integrates microelectronic technology, computer technology and information processing, and has the advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable work, etc. With the continuous development of LED display screen, more and more foldable LED display screens appear on the market.

[0055] Since the volume of the foldable LED display screen is usually large, the lifting folding device is needed to first adjust the LED display screen to a suitable height and fold it to a suitable angle, so as to facilitate the transportation and carrying of the LED display screen. At present, the automatic degree of the lifting folding device is low, and manual adjustment of the lifting height and folding angle of the LED display screen is needed, which is time-consuming and laborious.

[0056] Therefore, in order to solve the technical problems of low automatic degree and time-consuming adjustment of the lifting folding device at present, with reference to Figures 1 to 4The utility model provides a kind of LED display screen lifting folding device, including base 100, support 200, lifting mechanism 300, folding mechanism 400 and control mechanism 500.The frame of base 100 can be made of aluminium alloy material, the frame of base 100 can also be made of stainless steel material.Support 200 is connected to base 100, and support 200 has mounting surface, and mounting surface is suitable for installing LED display screen 600.Exemplarily, for example, LED display screen 600 and support 200 can be connected together by bolt.Lifting mechanism 300 is arranged in base 100, and lifting mechanism 300 is connected with support 200, for driving support 200 to move up and down along first direction X, and first direction X can be vertical longitudinal.Folding mechanism 400 is arranged in support 200, for driving support 200 to be partially folded along second direction Y perpendicular to first direction X, and second direction Y can be horizontal transverse.Control mechanism 500 is electrically connected with lifting mechanism 300 and folding mechanism 400, for controlling the action of lifting mechanism 300 and folding mechanism 400, and control mechanism 500 can be PLC control system.

[0057] Specifically, in the embodiment, LED display screen 600 can be installed on support 200 by bolt, and the foldable area of LED display screen 600 can be arranged corresponding to folding mechanism 400.Lifting mechanism 300 can be automatically controlled to act by control mechanism 500, and lifting mechanism 300 can drive support 200 to move up and down along first direction X, and support 200 can drive LED display screen 600 to move up and down along first direction X, so as to realize the height adjustment of LED display screen 600 in first direction X.Meanwhile, folding mechanism 400 can be automatically controlled to act by control mechanism 500, and folding mechanism 400 can drive support 200 to be partially folded along second direction Y, and support 200 can drive LED display screen 600 to be partially folded along second direction Y, so as to realize the folding angle adjustment of LED display screen 600 in second direction Y, and reduce the overall unfolded volume of LED display screen 600 in second direction Y.

[0058] In the process that LED display screen 600 moves up and down along first direction X, wire connected with LED display screen 600 can move up and down by drag chain, to ensure that wire can move up and down synchronously with LED display screen 600.In the process that LED display screen 600 is folded along second direction Y, wire connected with LED display screen 600 can rotate by the axis of wire fixing end, to ensure that wire can be folded synchronously with LED display screen 600.

[0059] The LED display screen lifting and folding device provided by the embodiment has high automation, and the height and the folding angle of the LED display screen 600 do not need to be manually adjusted, which saves time and effort. After the control mechanism 500 receives the control instruction, the lifting mechanism 300 and the folding mechanism 400 are automatically controlled to perform corresponding actions, so that the support 200 drives the LED display screen 600 to be lifted to a suitable height or the support 200 drives the LED display screen 600 to be folded to a suitable angle, facilitating the transportation and carrying of the LED display screen 600, and ensuring that the LED display screen 600 is not damaged by knocking during transportation and carrying.

[0060] In some embodiments, the control mechanism 500 can only control any one of the lifting mechanism 300 and the folding mechanism 400 to act, or the control mechanism 500 can also control the lifting mechanism 300 and the folding mechanism 400 to act simultaneously. The control mechanism 500 can control the lifting mechanism 300 to output a single-point signal, that is, the lifting mechanism 300 can drive the support 200 to gradually lift, for example, each single-point signal output by the lifting mechanism 300 can drive the support 200 to lift only 1 mm each time. Alternatively, the control mechanism 500 can also control the lifting mechanism 300 to output a continuous signal, that is, the lifting mechanism 300 can drive the support 200 to directly lift to the maximum position. Similarly, the control mechanism 500 can control the folding mechanism 400 to output a single-point signal, that is, the folding mechanism 400 can drive the support 200 to gradually fold, for example, each single-point signal output by the folding mechanism 400 can drive the support 200 to fold only 1° each time. Alternatively, the control mechanism 500 can also control the folding mechanism 400 to output a continuous signal, that is, the folding mechanism 400 can drive the support 200 to directly fold to the maximum angle.

[0061] In some embodiments, referring to Figures 1 to 4 The support 200 includes a connection cross beam 210 and a connection longitudinal beam 220 arranged to cross each other, the connection cross beam 210 is connected with the folding mechanism 400, and the folding mechanism 400 can drive the connection cross beam 210 to partially fold in the second direction Y. The connection longitudinal beam 220 is connected with the lifting mechanism 300, and the lifting mechanism 300 can drive the connection longitudinal beam 220 to lift in the first direction X.

[0062] Specifically, in the embodiment, the support 200 can include two connection cross beams 210 parallel to each other and two connection longitudinal beams 220 parallel to each other, and the two connection cross beams 210 and the two connection longitudinal beams 220 are arranged to cross each other, respectively. The above structure is beneficial to improve the structural stability of the support 200, thereby ensuring that the support 200 can provide stable support for the LED display screen 600.

[0063] The connecting cross beams 210 can correspond to the length of the LED display screen 600, and the connecting longitudinal beams 220 can correspond to the width of the LED display screen 600. Since the length of the LED display screen 600 is larger than the width, the LED display screen 600 occupies more space along the length direction than along the width direction. The folding mechanism 400 can drive the connecting cross beams 210 to partially fold along the second direction Y, and the connecting cross beams 210 can drive the LED display screen 600 to partially fold along the length direction, thereby facilitating the reduction of the volume of the LED display screen 600 along the length direction and the transportation and handling of the LED display screen 600. In order to avoid the conflict between the lifting mechanism 300 and the folding mechanism 400 when driving the support 200, the lifting mechanism 300 can drive the connecting longitudinal beams 220 to lift along the first direction X, and the connecting longitudinal beams 220 can drive the LED display screen 600 to lift along the width direction, thereby facilitating the adaptive adjustment of the position of the LED display screen 600 according to the size of the space.

[0064] In some embodiments, with reference to Figure 3 The lifting mechanism 300 includes a first driving motor 310, a transmission part 320, and a sliding block 330. The first driving motor 310 has a first driving shaft, which can be a servo motor or a stepper motor. The transmission part 320 is connected to the first driving shaft and can rotate under the drive of the first driving shaft. The transmission part 320 is a lead screw nut transmission mechanism or an electric cylinder transmission mechanism (it should be noted that the specific structure of the lead screw nut transmission mechanism and the electric cylinder transmission mechanism can be referred to the prior art, which will not be described here). The sliding block 330 is connected to one end of the transmission part 320 away from the first driving motor 310, and the sliding block 330 and the support 200 are connected. The sliding block 330 can lift along the first direction X under the drive of the transmission part 320.

[0065] The base 100 can be provided with a stand column 110, and the lifting mechanism 300 can be arranged in the stand column 110 to ensure the safety of the lifting mechanism 300 during use and prevent the lifting mechanism 300 from being damaged by knocking. In addition, arranging the lifting mechanism 300 in the stand column 110 facilitates the simplification of the external structure of the LED display screen lifting and folding device. The stand column 110 can be provided with a sliding rail, and the sliding block 330 and the sliding rail cooperate to enable the sliding block 330 to move along the first direction X on the sliding rail.

[0066] Specifically, in the present embodiment, when the lifting mechanism 300 is in action, the first driving shaft of the first driving motor 310 drives the transmission part 320 to rotate, the transmission part 320 drives the sliding block 330 to move up and down along the first direction X, the sliding block 330 drives the bracket 200 to move up and down along the first direction X, and the bracket 200 drives the LED display screen 600 to move up and down along the first direction X, so as to realize the height adjustment of the LED display screen 600. When the lifting mechanism 300 stops action, the transmission part 320 no longer rotates, and the sliding block 330 is kept at the target position, at this time, the bracket 200 and the LED display screen 600 are also kept at the target position, so as to realize the height positioning of the LED display screen 600.

[0067] In some embodiments, referring to Figure 4 , the folding mechanism 400 comprises a second driving motor 410, a connecting shaft 420 and a folding part 430. The second driving motor 410 has a second driving shaft, and the second driving motor 410 can be a servo motor or a stepping motor. The connecting shaft 420 is connected with the second driving shaft, and the connecting shaft 420 can rotate under the driving of the second driving shaft. The folding part 430 is connected with the connecting shaft 420, and the folding part 430 is connected with the bracket 200. The folding part 430 comprises a fixed end and a movable end, the fixed end of the folding part 430 is connected with the non-folding area of the bracket 200, and the movable end of the folding part 430 is connected with the foldable area of the bracket 200. The folding part 430 can be a hinge structure.

[0068] Specifically, in the present embodiment, when the folding mechanism 400 is in action, the second driving shaft of the second driving motor 410 drives the connecting shaft 420 to rotate, the connecting shaft 420 drives the folding part 430 to unfold or fold along the second direction Y, the folding part 430 drives the bracket 200 to fold to a certain angle, and the bracket 200 drives the LED display screen 600 to fold to a certain angle, so as to realize the folding angle adjustment of the LED display screen 600. When the folding mechanism 400 stops action, the connecting shaft 420 no longer rotates, and the folding part 430 is kept at the target position, at this time, the bracket 200 and the LED display screen 600 are also kept at the target position, so as to realize the folding angle positioning of the LED display screen 600.

[0069] In some embodiments, referring to Figures 1 to 4The base 100 is provided with a machine box 120. The machine box 120 can be connected to the base 100 by bolts, or the machine box 120 can be welded to the base 100. The control mechanism 500 is arranged in the machine box 120. The machine box 120 can effectively protect the control mechanism 500, prevent the control mechanism 500 from being damaged or damp, and ensure the electrical safety of the control mechanism 500. The outer wall of the machine box 120 is provided with a control panel 121. The control panel 121 is provided with control buttons. For example, the control buttons include but are not limited to power on button, up button, down button, unfolding button, folding button, etc. The control panel 121 is electrically connected with the control mechanism 500, and is used for inputting control instructions to the control mechanism 500.

[0070] Specifically, in the embodiment, the operator can input corresponding control instructions to the control mechanism 500 by pressing the control buttons on the control panel 121, and then use the control mechanism 500 to control the LED display screen lifting and folding device to perform corresponding actions. For example, when the LED display screen 600 needs to be lifted, the operator can first press the power on button, and then press the up button after the control mechanism 500 is started. At this time, the control mechanism 500 controls the lifting mechanism 300 to act, and the lifting mechanism 300 drives the support 200 to move upward along the first direction X, so that the support 200 drives the LED display screen 600 to move upward, thereby adjusting the height of the LED display screen 600. The operation mode of other control instructions (such as down instruction, folding instruction, unfolding instruction, etc.) can refer to the above embodiment, and will not be described here.

[0071] In some embodiments, the control mechanism 500 includes a wireless communication module. The wireless communication module is adapted to be electrically connected with a controller 700. The controller 700 is used for remotely controlling the control mechanism 500. The controller 700 can be a remote controller, a mobile terminal (mobile phone, tablet), etc. The wireless communication module can be a Bluetooth module, a Wi-Fi module or an infrared module.

[0072] Specifically, in the embodiment, the operator can input corresponding control instructions to the control mechanism 500 by pressing the control buttons on the control panel 121, and then use the control mechanism 500 to control the LED display screen lifting and folding device to perform corresponding actions. For example, when the LED display screen 600 needs to be lifted, the operator can first press the power on button, and then press the up button after the control mechanism 500 is started. At this time, the control mechanism 500 controls the lifting mechanism 300 to act, and the lifting mechanism 300 drives the support 200 to move upward along the first direction X, so that the support 200 drives the LED display screen 600 to move upward, thereby adjusting the height of the LED display screen 600. The operation mode of other control instructions (such as down instruction, folding instruction, unfolding instruction, etc.) can refer to the above embodiment, and will not be described here.

[0073] In some embodiments, the folding mechanism 400 drives the folding angle a of the support 200 in the second direction Y to satisfy: -150°≤a≤150°. Exemplarily, the value of a can be -150°, -90°, 0°, 90°, 150°, and the like.

[0074] Specifically, in the present embodiment, the positive and negative signs before the angles only represent the folding direction of the support 200, for example, the support 200 can drive the LED display screen 600 to fold towards the screen direction of the LED display screen 600, or the support 200 can also drive the LED display screen 600 to fold towards the backboard direction of the LED display screen 600.

[0075] By setting the folding angle in the above range, it is beneficial to increase the adjustment range of the support 200, so that the LED display screen 600 can effectively reduce the volume after folding, thereby facilitating the transportation and handling of the LED display screen 600, and at the same time, it can prevent the LED display screen 600 from colliding with itself and causing damage to the LED display screen 600.

[0076] In some embodiments, referring to Figures 1 to 4 The base 100 is provided with universal wheels 130 away from the support 200.

[0077] Specifically, in the present embodiment, the universal wheels 130 are beneficial to the overall movement of the LED display screen lifting and folding device, thereby facilitating the transportation and handling of the LED display screen 600.

[0078] It should be noted that other contents of the utility model for LED display screen lifting and folding device can refer to the prior art, which will not be described here.

[0079] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and drawings, or direct / indirect application in other related technical fields under the utility model concept of the utility model is included in the patent protection range of the utility model.
