Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of display equipment, and in particular to a display equipment support, a display equipment, and a control method. BACKGROUND

[0002] Currently, some display equipment such as display boards and display screens are used in outdoor or various large venues for publicity activities, which display and publicize information in the form of pictures or videos to better display information to the audience on site.

[0003] Taking a display screen as an example, the cost of installing a large display screen on a building is too high in many temporary activity sites, so a screen is generally assembled on site for publicity activities. Specifically, the large screen assembled on site is generally connected and pulled by a heavy object and a rope or a supporting rod and a screen support frame, or some simple supporting mechanisms are used to enhance stability to ensure the stability of the large screen.

[0004] However, once sudden gale weather or extreme conditions are encountered, the simple stability structure is difficult to ensure safety, and the display screen may be tilted, and the impact force during tilting may easily cause the display screen to be severely damaged. Moreover, if personnel in the tilting range do not timely move away, the personnel life safety may be endangered, and the personnel hit under the large display screen can only be rescued by stirring, which delays valuable first aid time. SUMMARY

[0005] In view of this, embodiments of the present application provide a display equipment support, a display equipment, and a control method, which can reduce damage to the display equipment body caused by the impact force of tilting and can reduce harm to personnel in the tilting range.

[0006] In a first aspect, embodiments of the present application provide a display equipment support, which comprises a base, a frame, and a plurality of buffer assemblies. The frame is fixedly connected to the base and comprises a front frame and a rear frame fixedly connected together, and the front frame is used to set a display equipment body. The plurality of buffer assemblies are arranged close to the outer edges of the frame and are located on different sides of the frame. Each buffer assembly comprises an abutting member, and the plurality of buffer assemblies have at least a complete state. In the complete state, one end of the abutting member is connected to the frame, the other end extends along the thickness direction of the frame and extends out of the frame, and the plurality of abutting members and the frame enclose a tilting avoidance space.

[0007] The display equipment support provided by the embodiments of the present application is provided with a plurality of buffer assemblies. When the plurality of buffer assemblies are in a complete state, the free end of the abutting piece is higher than the frame in the thickness direction of the frame. Thus, when the frame is tilted, the abutting pieces of the plurality of buffer assemblies will first contact the ground, and the frame or the display equipment body on the frame will not first contact the ground, thereby reducing the damage to the display equipment body caused by the impact force of the tilting. Moreover, the plurality of buffer assemblies are arranged close to the outer edge of the frame, and when in the complete state, the plurality of abutting pieces and the frame enclose a tilting avoidance space.

[0044] In the embodiments of the present application, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "including a…" does not exclude the existence of other same elements in the process, method, article or device including the element.

[0045] In the embodiments of the present application, the word "exemplary" or "for example" is used to mean serving as an example, instance, or illustration. Any implementation or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being preferred or advantageous over other implementations or design solutions. In fact, the word "exemplary" or "for example" is used to present concepts in a concrete manner.

[0046] The embodiments of the present application provide a display device, referring to Figure 1 and Figure 2 , comprising a display device support 100 and a display device body 200, the display device body 200 is arranged on the front frame of the display device support 100, and is used to display information.

[0047] The display device body 200 of the embodiments of the present application can be a display board, a billboard, a display electronic screen, or other display devices with large size. The display device at least comprises a display device support 100 and a display device body 200. Due to the large size, the display device can be affected by strong wind or extreme conditions, and can be prone to falling. In order to reduce the loss or personnel injury caused by falling, the display device support 100 of the embodiments of the present application is newly designed. If falling occurs, the display device support can reduce the damage of the impact force caused by falling to the display device body 200, and can reduce the injury to the personnel in the falling range.

[0048] Specifically, the embodiments of the present application further provide a display device support 100, which can be used for any display device body 200 that needs a support to be supported. Referring to Figure 2 and Figure 3 , the display device support 100 comprises a base 1, a frame 2 and a plurality of buffer assemblies 3. The frame 2 is fixedly connected to the base 1, and comprises a front frame 21 and a rear frame 22 fixedly connected together, and the front frame 21 is used to arrange the display device body 200. The plurality of buffer assemblies 3 are arranged close to the outer edge of the frame 2, and are located on different sides of the frame 2. Each buffer assembly 3 comprises an abutting piece 31. The plurality of buffer assemblies 3 at least have a complete state. In the complete state, one end of the abutting piece 31 is connected to the frame 2, and the other end extends along the thickness direction of the frame 2 and extends out of the frame 2. The plurality of abutting pieces 31 and the frame 2 enclose a falling avoiding space 4.

[0049] The display equipment support 100 provided by the embodiments of the present application is provided with a plurality of buffer assemblies 3. When the plurality of buffer assemblies 3 are in a complete state, the free end of the abutting piece 31 is higher than the frame 2 along the thickness direction of the frame 2. Thus, when the frame 2 is tilted, the abutting piece 31 of the plurality of buffer assemblies 3 will first contact the ground, and the frame 2 or the display equipment body 200 on the frame 2 will not first contact the ground, thereby reducing the damage to the display equipment body 200 caused by the impact force of the tilting. Moreover, the plurality of buffer assemblies 3 are arranged close to the outer edge of the frame 2, and when in the complete state, the plurality of abutting pieces 31 and the frame 2 enclose a tilting avoidance space 4. When the frame 2 is tilted, the tilting avoidance space 4 will not contact the ground, and can provide an avoidance area for the personnel in the tilting range, thereby also reducing the harm to the personnel in the tilting range.

[0050] It should be noted that, when the plurality of buffer assemblies 3 are in the complete state, the plurality of abutting pieces 31 and the frame 2 enclose the tilting avoidance space 4. In order to facilitate personnel to avoid, the tilting avoidance space 4 should have sufficient size and thickness to meet the personnel's avoidance, for example, the size of the plurality of abutting pieces 31 being higher than the frame 2 is greater than the thickness of the personnel's body. In addition, when the frame 2 is tilted, generally, two situations of front tilting and back tilting will occur. When back tilting, the tilting avoidance space 4 is enclosed by the plurality of abutting pieces 31 and the back frame 22. When front tilting, the tilting avoidance space 4 is enclosed by the plurality of abutting pieces 31 and the front frame 21. In this case, the thickness of the display equipment body 200 also needs to be considered in the tilting avoidance space 4 enclosed by the plurality of abutting pieces 31 and the front frame 21, and thus the actual space available for personnel to avoid is the space enclosed by the plurality of abutting pieces 31 and the display equipment body 200.

[0051] In addition, the specific structure of the frame 2 of the embodiments of the present application is not limited. Under the premise of supporting the display equipment body 200, the structure is as stable and reliable as possible, is not easy to damage and tilt, and has good economy. For example, in some embodiments of the present application, the frame 2 includes a front frame 21, a back frame 22, a connecting beam 23 connecting the front frame 21 and the back frame 22, and a reinforcing rod 24. The connecting beam 23 connects and fixes the four side edges of the front frame 21 and the back frame 22. The reinforcing rod 24 is uniformly and spacedly distributed in the middle of the front frame 21 and the back frame 22, so that the entire frame 2 forms a stable and solid display equipment support 100.

[0052] The base 1 is arranged below the frame 2 and is used for supporting on the ground. The width of the base 1 can be greater than the overall thickness of the frame 2, so as to improve the anti-tilting capability of the frame 2. A support connecting frame 11 for supporting and connecting the frame 2 can be arranged between the base 1 and the frame 2.

[0053] In addition, the display equipment support 100 of the embodiments of the present application can also be connected with a heavy object through a rope when in use, so as to enhance the stability.

[0054] In order to prevent the front and rear dumping, the plurality of abutting members 31 can have the protruding end in the front frame 21 and also have the protruding end in the rear frame 22, so that the dumping avoidance space 4 can be formed in front of and behind the frame 2. In order to reduce the cost and the overall weight, in some embodiments, the plurality of abutting members 31 can be arranged in a manner that can be movably connected with the frame 2 and can change the pose, that is, through the change of the pose of the plurality of abutting members 31, the dumping avoidance space 4 can be formed in front of or behind the frame 2.

[0055] The plurality of abutting members 31 are movably connected with the frame 2 and can change the pose in various ways, for example, rotation, swing, forward and backward sliding, telescopic rod, etc. In the following, the application embodiment will be described in detail in the implementation way of rotation.

[0056] Referring to Figure 2 , Figure 4 and Figure 5 , the abutting member 31 is rotatably connected with the frame 2, and the abutting member 31 can be rotated to a first position and a second position relative to the frame 2. When the abutting member 31 is located at the first position, the abutting member 31 extends along the direction from the front frame 21 to the rear frame 22 and protrudes out of the rear frame 22. When the abutting member 31 is located at the second position, the abutting member 31 extends along the direction from the rear frame 22 to the front frame 21 and protrudes out of the front frame 21. The end of the abutting member 31 protruding out of the frame 2 is higher than the display device body 200 arranged on the front frame 21. When the abutting member 31 is located at the first position or the second position, the buffer assembly 3 is in a complete state.

[0057] By rotating the abutting member 31 relative to the frame 2, the abutting member 31 can be switched between the first position and the second position, so that the abutting member 31 can extend along the direction from the front frame 21 to the rear frame 22 and protrude out of the rear frame 22 to form the rear dumping avoidance space 4, or the abutting member 31 can extend along the direction from the rear frame 22 to the front frame 21 and protrude out of the front frame 21 to form the front dumping avoidance space 4.

[0058] It should be noted that the rotation of the abutting member 31 and the frame 2 can be controlled by a driving member, and further, the abutting member 31 can be automatically controlled to switch between the first position and the second position.

[0059] There are many specific implementation ways for the rotatable connection between the abutting member 31 and the frame 2, for example, through the shaft hinge, spherical connection, etc. The hinge way and structure of the application embodiment can be designed as follows: referring to Figure 3In some embodiments, each buffering assembly 3 comprises two opposite hinge blocks 32 arranged on the frame 2, and the abutting piece 31 is hinged between the two hinge blocks 32 through a first hinge shaft 33, the extension direction of the first hinge shaft 33 is consistent with the extension direction of the outer edge of the frame 2 on which the abutting piece 31 is arranged, and the abutting piece 31 can be switched between the first position and the second position when rotating around the first hinge shaft 33.

[0060] The two opposite hinge blocks 32 are arranged at intervals, leaving a space for the end of the abutting piece 31 to extend into, and a hinge hole can be opened at the end of the abutting piece 31, the first hinge shaft 33 passes through the hinge hole at the end of the abutting piece 31, and the two ends of the first hinge shaft 33 are connected to the two hinge blocks 32 respectively. At this time, the two ends of the first hinge shaft 33 can be rotated relative to the two hinge blocks 32, thereby realizing the hinge connection of the abutting piece 31 and the frame 2; or the first hinge shaft 33 and the abutting piece 31 can be rotatably connected through the hinge hole, thereby realizing the hinge connection of the abutting piece 31 and the frame 2.

[0061] After the abutting piece 31 rotates relative to the frame 2, the switching between the first position and the second position is realized, wherein, in order to determine the limit of the first position and the second position, a corresponding blocking structure can be arranged at the hinge connection between the abutting piece 31 and the frame 2, or on the rotation track of the abutting piece 31, so that when the abutting piece 31 rotates to abut against the blocking structure, it is just in the first position or the second position.

[0062] In some embodiments of the present application, when the abutting piece 31 is in the first position, the abutting piece 31 abuts against the rear frame 22 of the frame 2, and when the abutting piece 31 is in the second position, the abutting piece 31 abuts against a pre-arranged blocking structure. For example, as shown in Figure 3 The buffering assembly 3 comprises a limiting block 34, when the abutting piece 31 is in the first position, the abutting piece 31 abuts against the frame 2 to limit the rotation of the abutting piece 31 towards the rear frame 22, and when the abutting piece 31 is in the second position, the abutting piece 31 abuts against the limiting block 34 to limit the rotation of the abutting piece 31 towards the front frame 21.

[0063] The limiting of the abutting piece 31 by the limiting block 34 can prevent the abutting piece 31 from rotating too much and colliding with the display device body 200 located at the front frame 21.

[0064] The abutting piece 31 can have various forms, such as plate-shaped, block-shaped, strip-shaped, rod-shaped, etc., and during the switching of the pose of the abutting piece 31, the shape of the abutting piece 31 can collide with the side edge of the display device body 200 located at the front frame 21. In order to prevent this problem, with reference to Figure 5In some embodiments of the present application, the middle part of the abutting member 31 is bent to form an avoiding part 311, which is used to avoid the display device body 200 arranged on the front frame 21 when the abutting member 31 is in the second position, so as to avoid the collision between the abutting member 31 and the display device body 200.

[0065] In order to further reduce the impact force generated by the dumping, the abutting member 31 can be further designed with a buffering mechanism. For details, refer to Figure 5 、 Figure 6 and Figure 7 In some embodiments of the present application, the abutting member 31 comprises a connecting rod 312, a turnover plate 313 and a buffering member 314. One end of the connecting rod 312 is connected with the frame 2, and the other end is rotatably connected with the turnover plate 313, which extends out of the frame 2 along the thickness direction of the frame 2. The buffering member 314 is arranged between the connecting rod 312 and the turnover plate 313, and is used to apply a rotational restoring force to the turnover plate 313 to restore the initial state when the turnover plate 313 rotates relative to the connecting rod 312.

[0066] Since the buffering member 314 is arranged between the rotatably connected connecting rod 312 and the turnover plate 313, when the frame 2 is dumped, the turnover plate 313 first contacts the ground, and then rotates relative to the connecting rod 312. The rotating action triggers the function of the buffering member 314, which applies a rotational restoring force to the turnover plate 313 to restore the initial state. The rotational restoring force can buffer the impact generated during dumping, thereby further reducing a series of damages caused by dumping.

[0067] The buffering member 314 can be realized by some components with elasticity, such as springs, torsional springs, elastic ropes, etc. For details, refer to Figure 7 The connecting rod 312 and the turnover plate 313 are hinged through a second hinge shaft 315, and the buffering member 314 is a torsional spring arranged on the second hinge shaft 315. When the turnover plate 313 rotates relative to the connecting rod 312, the torsional spring elastically deforms to apply an elastic rotational restoring force to the turnover plate 313 to restore the initial state.

[0068] It should be noted that in order to facilitate the layout and operation of the turnover plate 313, a plurality of turnover plates 313 are arranged along the side edges of the frame 2, and the plurality of turnover plates 313 are connected by connecting rods 312, wherein the connecting rods 312 are three, two connecting rods 312 are arranged along the vertically extending side wall edges of the frame 2, and are used to be connected with the plurality of turnover plates 313 arranged along the vertically extending side wall edges of the frame 2 through a plurality of buffer members 314; and the other connecting rod 312 is arranged along the top edge of the frame 2 and extends, and is used to be connected with the plurality of turnover plates 313 arranged along the top edge of the frame 2 through a plurality of buffer members 314. Each connecting rod 312 is hinged to the frame 2 through a plurality of turnover folding rods 316, wherein the avoiding portion 311 formed by the middle part of the abutting piece 31 is arranged on the turnover folding rod 316.

[0069] In order to further buffer the impact force of dumping, some other buffer mechanisms such as buffer bag 53 can also be arranged in some embodiments of the present application.

[0070] For example, referring to Figure 2 and Figure 4 , the display support 100 comprises a medium buffer mechanism 5, the medium buffer mechanism 5 comprises a medium generator 51, a pipeline 52 and a buffer bag 53, the pipeline 52 communicates the medium generator 51 and the buffer bag 53, and the buffer bag 53 is arranged at the abutting piece 31.

[0071] The medium generator 51 can generate a medium for filling the buffer bag 53, and the medium can be various fluids such as liquid and gas, etc. By filling the buffer bag 53 with fluid medium, the buffer bag 53 also has the function of buffering the impact force, so that when the frame 2 is dumped, the medium generator 51 rapidly generates the medium, which is delivered into the buffer bag 53 through the pipeline 52, and the buffer bag 53 arranged at the abutting piece 31 contacts the ground first, which can greatly buffer the impact force of dumping. Moreover, when a large amount of medium rapidly fills into the buffer bag 53, the buffer bag 53 rapidly expands and occupies a large space, and then the buffer bag 53 contacts the ground first during dumping, which can absorb most of the impact force, and the buffer effect is good.

[0072] In order to facilitate the layout of the buffer bag 53 and to prevent the buffer bag 53 from being damaged when it is not inflated and exposed, in some embodiments, the buffer bag 53 is arranged in a closed space for protection, and when the buffer bag 53 is inflated, it can burst out of the closed space to play a buffering role. For example, referring to Figure 8 and Figure 9The turnover plate 313 has an accommodating space 317 inside, and at least one side wall of the turnover plate 313 has a breakable protection 3131. The buffer bag 53 is arranged in the accommodating space 317, and the medium generating mechanism outputs the buffer medium to the buffer bag 53 through the pipeline 52, and the breakable protection 3131 can be broken to expose the buffer bag 53 to the outside of the turnover plate 313.

[0073] The shape of the accommodating space 317 is not limited, Figure 8 The space structure is a cuboid. In addition, the breakable protection 3131 can be arranged on the side wall of the turnover plate 313 with a large extension surface, so as to facilitate the burst of the buffer bag 53.

[0074] In order to avoid that the pressure of the medium in the buffer bag 53 is too large to affect the buffer effect of the buffer bag 53, with reference to Figure 5 、 Figure 8 and Figure 9 In some embodiments, the turnover plate 313 is provided with a pressure relief valve 3132, and the pressure relief valve 3132 is located on the side of the turnover plate 313 opposite to the side provided with the breakable protection 3131. In this way, when the pressure in the buffer bag 53 is too large, a part of the medium can be discharged from the pressure relief valve 3132 to ensure the buffer performance of the buffer bag 53. Moreover, when the frame 2 is tilted, the pressure in the buffer bag 53 increases instantaneously at the moment when the buffer bag 53 contacts the ground, and at this moment, some medium in the buffer bag 53 can be discharged from the pressure relief valve 3132 to absorb the impact force and protect the whole display device support 100 and the display device body 200.

[0075] With reference to Figure 2 and Figure 4 , a pipeline 52 for conveying medium is shown, which includes a conveying pipeline 521, a layout pipeline 522 and a terminal hose 523. The layout pipeline 522 is arranged close to the outer edge of the frame 2 and extends in the same direction as the outer edge of the frame 2. The conveying pipeline 521 is used to connect the medium generating mechanism and the layout pipeline 522, and the terminal hose 523 is used to connect the layout pipeline 522 and the buffer bag 53.

[0076] The layout pipeline 522 is arranged close to the outer edge of the frame 2, and the layout pipeline 522 and the corresponding buffer bag 53 are connected through the terminal hose 523, and the conveying pipeline 521 is used to connect the medium generating mechanism 51 and the layout pipeline 522.

[0077] With reference to Figure 2 and Figure 4The layout pipeline 522 can include a layout pipeline 522 located at two vertical side walls of the frame 2 and a layout pipeline 522 located at the top of the frame 2, the medium generator 51 is arranged in the frame 2 in a position close to the bottom and located in the middle in the horizontal direction, and the conveying pipeline 521 includes a middle vertically arranged conveying pipeline 521 for connecting the top layout pipeline 522, and a bottom horizontally extended conveying pipeline 521 for connecting the layout pipeline 522 at the side wall. Among them, the medium generator 51 has a certain weight, which is arranged in the middle of the frame 2 in a lower position, on the one hand, the weight of the medium generator 51 will not make the frame 2 easy to fall, on the other hand, the medium generator 51 can also be equivalent to a counterweight for the frame 2, which can further increase the stability of the frame 2 and is not easy to fall.

[0078] It should be noted that the pipeline 52 can be fixed in the frame 2, and the fixed mode has various implementation modes, for example, the layout pipeline 522 is fixed on the frame 2 to realize the fixation of the entire pipeline 52, for example, the frame 2 is fixed on the frame 2. Figure 5 The layout pipeline 522 is provided with a fixing rod 524, which fixes the layout pipeline 522 and the frame 2. Specifically, the fixing rod 524 can be sleeved and fixed on the reinforcing rod 24 through a connecting sleeve 525.

[0079] The display device body 200 arranged on the front frame 21 may have dust in the use process, in order to clean it, in some embodiments of the present application, the display device support 100 includes a dust removal mechanism 6, which is arranged on the frame 2 close to the front frame 21, and is used for cleaning the display device body 200 arranged on the front frame 21.

[0080] For example, referring to Figure 6 The dust removal mechanism 6 includes a sliding rail mechanism 61, an extension rod 62 and a dust removal piece 63, the sliding rail mechanism 61 is arranged on both sides of the front frame 21 in the vertical direction, the extension rod 62 is connected with the sliding rail mechanism 61 and can move in the vertical direction along the sliding rail mechanism 61, and the dust removal piece 63 is located in front of the front frame 21 and connected with the sliding rail mechanism 61 through the extension rod 62.

[0081] In this way, through the sliding connection of the extension rod 62 and the sliding rail mechanism 61, the dust removal piece 63 can be driven to move up and down in front of the front frame 21 in the vertical direction, and then the dust removal piece 63 can perform dust removal operation on the display device body 200 arranged on the front frame 21.

[0082] The dust removal piece 63 can be a brush, dust removal cloth or other structure that can wipe dust, for example, referring to Figure 6In some embodiments of the present application, the dust removal member 63 comprises a dust removal roller brush 631 and a dust removal motor 632 for driving the dust removal roller brush 631 to rotate. In this way, when the dust removal member 63 slides with the extension rod 62 and the slide rail mechanism 61, the dust removal motor 632 can drive the dust removal roller brush 631 to rotate, and the dust removal roller brush 631 rotates while moving up and down, thereby effectively removing dust on the display device body 200.

[0083] It should be noted that the sliding mode between the extension rod 62 and the slide rail mechanism 61 can be completed by a driving member. For example, the slide rail mechanism 61 is an electric slide rail slider mechanism, or the slide rail mechanism 61 is a linear cylinder, etc.

[0084] In order to realize automatic control, the display device support 100 of the present application further comprises a controller and a dumping detection member. The dumping detection member is used to detect whether the display device support 100 is dumped. The controller is used to control the plurality of buffer assemblies 3 to be in the complete state when the dumping detection member detects that the display device support 100 is dumped, so that the plurality of abutting members 31 and the frame 2 enclose the dumping avoidance space 4. In this way, the controller can ensure that the frame 2 always remains in the complete state when dumping, and ensure the formation of the buffer impact force and the dumping avoidance space 4. The dumping detection member can be a gyroscope or a displacement sensor, etc.

[0085] On this basis, in the scheme that the abutting member 31 of the display device support 100 of the present application can switch between the first position and the second position, the controller can also automatically control the abutting member 31 to switch between the first position and the second position. According to the dumping direction of the frame 2, the controller controls the abutting member 31 to extend towards the dumping side, so as to ensure that the abutting member 31 can correctly buffer the dumping impact force.

[0086] Further, when the display device support 100 of the present application comprises the medium buffer mechanism 5, the controller is also used to control the medium buffer mechanism 5 to work to realize the buffering of the buffer bag 53 when the dumping detection member detects that the display device support 100 is dumped.

[0087] Again, when the display device support 100 of the present application comprises the dust removal mechanism 6, the controller can also be used to control the dust removal mechanism 6 to remove dust from the display device body 200 arranged on the display device support 100.

[0088] The present application also provides a control method for controlling the working mode of the display device support 100 of the above embodiments. Specifically, the control method provided by the present application comprises:

[0089] The dumping detection member detects information whether the display device support 100 is dumped;

[0090] When it is detected that the display device support 100 is about to fall, the controller controls the plurality of buffering components 3 to be in the complete state, so that the plurality of abutting pieces 31 and the frame 2 enclose the falling avoidance space 4.

[0091] The control method of the embodiments of the present application can accurately obtain whether the display device support 100 has fallen by detecting information about whether the display device support 100 has fallen. On this basis, if the display device support 100 has fallen, the plurality of buffering components 3 are controlled to be in the complete state, so that the plurality of abutting pieces 31 and the frame 2 enclose the falling avoidance space 4, thereby preparing a buffering posture, ensuring that the abutting pieces 31 of the plurality of buffering components 3 first contact the ground when falling, and reducing damage to the display device body 200 caused by the impact force of falling. Moreover, the falling avoidance space 4 enclosed by the plurality of abutting pieces 31 and the frame 2 can provide a refuge area for personnel in the falling range, thereby also reducing harm to personnel in the falling range.

[0092] When the abutting piece 31 is located at the first position or the second position, the buffering component 3 is in the complete state. The first position is that the abutting piece 31 extends out of the rear frame 22, and the second position is that the abutting piece 31 extends out of the front frame 21. The control method of the embodiments of the present application can be to detect the direction of the display device support 100 toward falling to perform specific actions, for example: when the falling direction is toward the front frame 21, the controller controls the abutting piece 31 to be located at the second position.

[0093] When the falling direction is toward the rear frame 22, the controller controls the abutting piece 31 to be located at the first position.

[0094] In the embodiments, the abutting piece 31 can be located between the first position and the second position in the normal state, for example, at a central position between the first position and the second position.

[0095] However, in such a mode, if falling occurs, the abutting piece 31 needs to be controlled to move regardless of the position of the abutting piece 31, and a certain time is required in this process.

[0096] Therefore, in order to possibly save this part of time, the control method further includes the following steps in some embodiments of the present application:

[0097] The controller controls the abutting piece 31 to be located at the first position.

[0098] The falling detection piece detects information about whether the display device support 100 has fallen, and judges the direction of the falling direction.

[0099] When the falling direction is toward the front frame 21, the controller controls the abutting piece 31 to move from the first position to the second position.

[0100] When the falling direction is toward the rear frame 22, the controller keeps the abutting piece 31 at the first position.

[0101] In this way, the abutting members 31 are in the first position in the normal state, i.e., in a complete state, and no adjustment of the position of the abutting members 31 is needed when the dumping direction is toward the rear frame 22, which reduces the operation process and saves time.

[0102] Of course, in the above embodiment, if the dumping direction is toward the front frame 21, the controller controls the abutting members 31 to move from the first position to the second position with a longer stroke, which is also time-consuming. Therefore, in some embodiments, the control method further comprises:

[0103] The controller controls the abutting members 31 to be in the second position;

[0104] The dumping detection member detects information about whether the display device support 100 is dumped and determines the dumping direction;

[0105] When the dumping direction is toward the front frame 21, the controller keeps the abutting members 31 in the second position;

[0106] When the dumping direction is toward the rear frame 22, the controller controls the abutting members 31 to move from the second position to the first position.

[0107] In some embodiments of the present application, when the display device support 100 comprises the medium buffering mechanism 5, the control method further comprises:

[0108] When the dumping detection member detects that the display device support 100 is dumped, the controller controls the medium buffering mechanism 5 to generate medium to buffer the dumping impact force.

[0109] In some embodiments of the present application, the control method further comprises:

[0110] When the dumping detection member detects that the dumping action has been completed, the controller waits to receive a manual control instruction;

[0111] When the controller receives the manual control instruction, the control of the corresponding buffering assembly 3 is unlocked.

[0112] After the entire dumping of the display device support 100 is completed, if there is a person in the dumping avoidance space 4, rescue is needed as soon as possible, at this time, the control of the corresponding buffering assembly 3 can be unlocked, and when the controller receives the manual control instruction, the rescuing person can open the buffering assembly 3 on one side by a manual way to rescue the person from that side.

[0113] In some embodiments of the present application, when the display device support 100 comprises the dust removal mechanism 6, the control method further comprises: when a dust removal instruction is received, the controller controls the dust removal mechanism 6 to clean the display device body 200 arranged on the front frame 21.

[0114] The above sequence numbers of the embodiments of the present application are only for description, and do not represent the advantages and disadvantages of the embodiments. The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
