The embodiment of the application provides a display device, referring to fig. 1 and 2, including a display device bracket 100 and a display device body 200, the display device body 200 is disposed on a front frame of the display device bracket 100, for displaying information.

The display device body 200 of the embodiment of the application may be a device for displaying larger sizes such as a display board, a billboard, a display electronic screen, etc., and at least includes the display device bracket 100 and the display device body 200, and due to the larger size, the display device body may be affected by strong wind or extreme conditions, and may have a toppling phenomenon. In order to reduce the loss or personnel injury that topples over the production, the display device of this application embodiment has carried out new design to display device support 100, if topples over, the display device support can reduce the damage to display device body 200 because of the impact force of toppling over, and can reduce the injury to the personnel of toppling over the within range.

In particular, embodiments of the present application also provide a display stand 100, which display stand 100 may be used with any display body 200 that requires a stand to support. Referring to fig. 2 and 3, the display device stand 100 includes a base 1, a frame 2, and a plurality of buffer assemblies 3, wherein the frame 2 is fixedly connected to the base 1, and includes a front frame 21 and a rear frame 22 that are fixedly connected together, and the front frame 21 is used for setting a display device body 200; the plurality of buffer assemblies 3 are arranged close to the outer edge of the frame 2 and are at least 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, one end of each abutting piece 31 is connected with the frame 2 in the complete state, the other end of each abutting piece extends along the thickness direction of the frame 2 and extends out of the frame 2, and the plurality of abutting pieces 31 and the frame 2 enclose a dumping avoiding space 4.

According to the display equipment bracket 100 provided by the embodiment of the application, due to the fact that the plurality of buffer assemblies 3 are arranged, when the plurality of buffer assemblies 3 are in a complete state, the free ends of the abutting pieces 31 are higher than the frame 2 along the thickness direction of the frame 2, so that when the frame 2 is toppled over, the abutting pieces 31 of the plurality of buffer assemblies 3 can firstly contact the ground, and the frame 2 or the display equipment body 200 on the frame 2 cannot contact the ground for the first time, and damage to the display equipment body 200 due to toppling impact force is reduced; moreover, because a plurality of buffer assemblies 3 are close to the outer edge setting of frame 2, when being in the perfect state, a plurality of butt piece 31 enclose into toppling over with frame 2 and dodge space 4, when frame 2 topples over, topples over and dodges space 4 and does not contact ground, can give the personnel in the scope of toppling over and dodge the region, and then also can reduce the injury to the personnel in the scope of toppling over.

It should be noted that, when the plurality of cushioning components 3 are in the complete state, the plurality of abutting pieces 31 and the frame 2 enclose the dumping avoiding space 4, so as to facilitate the avoidance of the personnel, the size and thickness of the plurality of abutting pieces 31 should be sufficient to meet the avoidance of the personnel, for example, the size of the plurality of abutting pieces 31 higher than the frame 2 is greater than the thickness of the body of the personnel; in addition, since two situations of forward and backward tilting generally occur when the frame 2 is tilted, when the frame is tilted backward, the tilting avoidance space 4 is surrounded by the plurality of abutting pieces 31 and the rear frame 22, and when the frame is tilted forward, the tilting avoidance space 4 is surrounded by the plurality of abutting pieces 31 and the front frame 21, in this case, the thickness of the display device body 200 needs to be considered in the tilting avoidance space 4 surrounded by the plurality of abutting pieces 31 and the front frame 21, and further, the space which can be practically avoided by a person is the space surrounded by the plurality of abutting pieces 31 and the display device body 200.

In addition, the specific structure of the frame 2 in the embodiment of the application is not limited, and the frame is stable and reliable in structure, not easy to damage and topple over as far as possible under the premise of meeting the requirement of supporting the display device body 200, and has better economical efficiency. For example, in some embodiments of the present application, the frame 2 includes a front frame 21, a rear frame 22, and a connection beam 23 connecting the front frame 21 and the rear frame 22, and a reinforcing rod 24, where the connection beam 23 connects and fixes four sides of the front frame 21 and the rear frame 22, and the reinforcing rods 24 are uniformly spaced in the middle of the front frame 21 and the rear frame 22, so that the entire frame 2 forms a stable and solid display device stand 100.

The base 1 is disposed below the frame 2 for supporting on the ground, the width of the base 1 may be greater than the overall thickness of the frame 2 to improve the tilting prevention capability of the frame 2, and a supporting connection frame 11 for supporting and connecting the frame 2 may be disposed between the base 1 and the frame 2.

Also, the display stand 100 of the present embodiment may also be used to attach the frame 2 to a weight via a rope to enhance stability.

In order to prevent forward and backward tilting, the plurality of abutments 31 may have protruding ends at the front frame 21 and protruding ends at the rear frame 22, so that the tilt avoiding space 4 is formed both in front of and behind the frame 2. In order to reduce the cost and the overall weight, in some embodiments, a plurality of abutments 31 may be provided so as to be movably connected to the frame 2, in such a manner that the pose change is enabled, that is, by the pose change of the plurality of abutments 31, the dumping avoiding space 4 may be formed in front of or behind the frame 2.

The plurality of abutting pieces 31 are movably connected with the frame 2, and various modes for realizing pose change, such as rotation, swinging, sliding back and forth, telescopic rod, etc., are exemplified, and in the following, the embodiment of the present application describes a rotation implementation mode in detail.

Referring to fig. 2, 4 and 5, the abutment 31 is rotatably connected with the frame 2, and the abutment 31 is rotatable to a first position and a second position with respect to the frame 2, when the abutment 31 is located at the first position, the abutment 31 extends in the direction from the front frame 21 to the rear frame 22 and protrudes out of the rear frame 22; when the abutting piece 31 is located at the second position, the abutting piece 31 extends along the direction from the rear frame 22 to the front frame 21 and extends out of the front frame 21, and one end of the abutting piece 31 extending out of the frame 2 is higher than the display device body 200 arranged on the front frame 21; when the abutting piece 31 is located at the first position or the second position, the buffer assembly 3 is in a complete state.

Through the rotation of the abutting piece 31 and the frame 2, the first position and the second position of the abutting piece 31 are switched, so that the abutting piece 31 can extend along the direction from the front frame 21 to the rear frame 22 and extend out of the rear frame 22 to form a rear dumping avoiding space 4, or the abutting piece 31 can extend along the direction from the rear frame 22 to the front frame 21 and extend out of the front frame 21 to form a front dumping avoiding space 4.

It should be noted that the rotation of the abutment member 31 and the frame 2 may be controlled by one driving member, and further, the automatic control of the abutment member 31 to switch back and forth between the first position and the second position may be achieved.

There are many specific implementations of the rotatable connection of the abutment 31 with the frame 2, for example, through a hinge, a spherical connection, etc., the manner and structure of the opposite hinge illustrated in the embodiment of the present application may be designed as follows: referring to fig. 3, in some embodiments, each of the buffer assemblies 3 includes two opposite hinge blocks 32 provided on the frame 2, the abutment 31 is hinged between the two hinge blocks 32 by a first hinge shaft 33, an extending direction of the first hinge shaft 33 coincides with an extending direction of an outer edge of the frame 2 where the abutment 31 is provided, and the abutment 31 is switchable between a first position and a second position when rotated about the first hinge shaft 33.

Through two opposite hinge blocks 32 interval setting, leave the space that the tip of butt spare 31 stretched into in the centre, can offer the hinge hole at the tip of butt spare 31, pass the hinge hole of the tip of butt spare 31 through first hinge 33, and the both ends of first hinge 33 are connected respectively on two hinge blocks 32. At this time, both ends of the first hinge shaft 33 may be rotatable with respect to the two hinge blocks 32, thereby realizing the hinge of the abutting piece 31 and the frame 2; the first hinge shaft 33 and the abutting piece 31 may be rotatably connected through a hinge hole, and thus the abutting piece 31 and the frame 2 may be hinged.

After the abutting piece 31 rotates relative to the frame 2, the first position and the second position are switched, wherein in order to limit the first position and the second position, a corresponding blocking structure can be arranged at a position where the abutting piece 31 is rotatably connected with the frame 2 or on a rotating track of the abutting piece 31, so that the abutting piece 31 is just in the first position or the second position when being rotated to abut against the blocking structure.

In some embodiments of the present application, when the abutment 31 is in the first position, the abutment 31 abuts against the rear frame 22 of the frame 2, and when the abutment 31 is in the second position, the abutment 31 abuts against a preset blocking structure. For example, as shown in fig. 3, the buffer assembly 3 includes a stopper 34, when the abutment 31 is located at the first position, the abutment 31 abuts against the frame 2 to stop the abutment 31 from continuing to rotate toward the rear frame 22; when the abutting piece 31 is located at the second position, the abutting piece 31 abuts against the limiting block 34 to limit the abutting piece 31 to continue rotating towards the front frame 21.

The limiting block 34 limits the abutting piece 31, so that the abutting piece 31 can be prevented from rotating too much to hurt the display equipment body 200 positioned at the front frame 21.

The shape of the abutment member 31 may be selected from various shapes, such as a plate shape, a block shape, a bar shape, a rod shape, etc., in the process of changing the pose of the abutment member 31, since the shape of the abutment member 31 may collide with the side edge of the display device body 200 located at the front frame 21, in order to prevent this problem, referring to fig. 5, in some embodiments of the present application, the middle portion of the abutment member 31 is bent to form the avoiding portion 311, and when the abutment member 31 is located at the second position, the avoiding portion 311 is used to avoid the display device body 200 disposed on the front frame 21, so as to avoid the collision of the abutment member 31 itself with the display device body 200.

In order to further reduce the impact force generated by the tilting, the abutting member 31 may be further provided with a buffer mechanism, and referring to fig. 5, 6 and 7, in some embodiments of the present application, the abutting member 31 includes a connecting rod 312, a tilting plate 313 and a buffer member 314, one end of the connecting rod 312 is connected with the frame 2, the other end is rotatably connected with the tilting plate 313, extends in the thickness direction of the frame 2, and the tilting plate 313 protrudes out of the frame 2, the buffer member 314 is disposed between the connecting rod 312 and the tilting plate 313, and when the tilting plate 313 rotates relative to the connecting rod 312, the buffer member 314 is used to apply a rotational holding force to the tilting plate 313 to restore the initial state.

Since the buffer 314 is provided between the rotatably connected connection bar 312 and the turnover plate 313, when the frame 2 is dumped, the turnover plate 313 firstly contacts the ground and then rotates relative to the connection bar 312, the rotating action triggers the function of the buffer 314, and the rotation maintaining force for restoring the initial state is applied to the turnover plate 313, and can buffer the impact generated during dumping, thereby further reducing a series of injuries caused by dumping.

The buffer 314 may be implemented by some members having elasticity, such as a spring, a torsion spring, an elastic rope, etc., for example, referring to fig. 7, the connection rod 312 and the flipping plate 313 are hinged by the second hinge shaft 315, and the buffer 314 is a torsion spring provided on the second hinge shaft 315, and when the flipping plate 313 rotates with respect to the connection rod 312, the torsion spring is elastically deformed to apply an elastic rotation maintaining force to the flipping plate 313 to restore an initial state.

It should be noted that, for convenience of layout and operation, the plurality of the flipping plates 313 are provided along the side edges of the frame 2, the plurality of flipping plates 313 are connected by the connecting bars 312, wherein the number of the connecting bars 312 is three, two connecting bars 312 are provided along the vertically extending side edges of the frame 2, for connection with the plurality of flipping plates 313 provided along the vertically extending side edges of the frame 2 by the plurality of buffers 314; another connecting bar 312 is provided extending along the top edge of the frame 2 for connection with a plurality of flipping panels 313 provided along the top edge of the frame 2 by a plurality of bumpers 314. Each connecting rod 312 is hinged to the frame 2 through a plurality of turning rods 316, wherein the avoiding portion 311 formed by bending the middle portion of the abutting piece 31 is disposed on the turning rods 316.

In order to further buffer the impact force of dumping, some other buffer mechanisms, such as buffer bags 53, may be further provided in some embodiments of the present application.

By way of example, referring to fig. 2 and 4, the display device stand 100 comprises a media buffer mechanism 5, the media buffer mechanism 5 comprising a media generator 51, a conduit 52 and a buffer bladder 53, the conduit 52 communicating the media generator 51 with the buffer bladder 53, the buffer bladder 53 being disposed at the abutment 31.

The medium generator 51 may generate a medium for filling the buffer bag 53, the medium may be various fluids, such as liquid and gas, and the buffer bag 53 may also have a buffer impact force by filling the buffer bag 53 with the fluid medium, so that when the frame 2 is dumped, the medium generator 51 rapidly generates the medium, and the medium is conveyed into the buffer bag 53 through the pipe 52, and the buffer bag 53 disposed at the abutting member 31 contacts the ground before the frame 2, so that the dumped impact force may be buffered to a great extent. When a large amount of medium is rapidly filled into the buffer bag 53, the buffer bag 53 rapidly expands, occupies a large space, and the buffer bag 53 contacts the ground before the abutting piece 31 when toppling over, so that most of impact force can be absorbed, and the buffer effect is good.

To facilitate placement of the cushion bladder 53, and to facilitate placement of the cushion bladder 53 in an uninflated condition, the cushion bladder 53 is, in some embodiments, protected by being disposed within an enclosed space from which the cushion bladder 53 may burst when inflated, thereby providing cushioning. For example, referring to fig. 8 and 9, the inside of the flipping plate 313 has a receiving space 317, at least one side wall of the flipping plate 313 has a frangible guard 3131, the buffer pouch 53 is disposed in the receiving space 317, and the medium generating mechanism outputs the buffer medium to the buffer pouch 53 through the pipe 52, and breaks the frangible guard 3131 to expose the buffer pouch 53 to the outside of the flipping plate 313.

The shape of the accommodating space 317 is not limited, and a rectangular parallelepiped space structure is shown in fig. 8. In addition, frangible guard 3131 may be a sidewall disposed over a larger extension of flip plate 313 to facilitate burst of buffer capsule 53.

In order to avoid that the buffer effect of the buffer bag 53 is affected by an excessive pressure of the medium in the buffer bag 53, referring to fig. 5, 8 and 9, in some embodiments, a relief valve 3132 is provided on the flipping plate 313, and the relief valve 3132 is located on the opposite side of the flipping plate 313 where the frangible guard 3131 is provided. In this way, when the pressure in the buffer bladder 53 is excessive, a part of the medium may be discharged from the pressure release valve 3132 to secure the buffer performance of the buffer bladder 53. Moreover, at the moment that the cushion bag 53 contacts the ground when the frame 2 is toppled over, the pressure inside the cushion bag 53 is instantaneously increased, and at this time, some medium inside the cushion bag 53 may be discharged from the pressure release valve 3132, so as to absorb impact force, and protect the whole display apparatus bracket 100 and the display apparatus body 200.

Referring to fig. 2 and 4, there is shown an arrangement of the duct 52 for transporting the medium, the duct 52 including a transport duct 521, a layout duct 522 and a terminal hose 523, the layout duct 522 being disposed near the outer edge of the frame 2 and being in agreement with the extending direction of the outer edge of the frame 2, the transport duct 521 being for communicating the medium generating mechanism with the layout duct 522, the terminal hose 523 being for communicating the layout duct 522 with the buffer bag 53.

The layout duct 522 is provided near the outer edge of the frame 2, communicating the layout duct 522 with the corresponding buffer bag 53 through the terminal hose 523, and the delivery duct 521 is used to communicate the medium generator 51 with the layout duct 522.

Referring to fig. 2 and 4, the layout duct 522 may include a layout duct 522 at two vertical sidewalls of the frame 2 and a layout duct 522 at a top of the frame 2, the medium generator 51 being disposed at a position near a lower side within the frame 2 and being disposed at a middle portion in a horizontal direction, the transfer duct 521 including a transfer duct 521 vertically disposed at a middle portion of the layout duct 522 for connecting the top, and a transfer duct 521 horizontally extending for connecting a bottom of the layout duct 522 at the sidewall. The medium generator 51 has a certain weight, and is disposed in a position of the middle of the frame 2 below, so that on one hand, the weight of the medium generator 51 does not enable the frame 2 to easily fall down, and on the other hand, the medium generator 51 can be equivalent to a weight for the frame 2, thereby further increasing the stability of the frame 2 and not easily fall down.

It should be noted that, the pipe 52 may be correspondingly fixed in the frame 2, and there are various ways of fixing the pipe 52, for example, by fixing the layout pipe 522 to the frame 2 to fix the whole pipe 52, referring to fig. 5, a fixing rod 524 is provided on the layout pipe 522, and the fixing rod 524 fixes the layout pipe 522 and the frame 2. Specifically, the fixing rod 524 may be sleeved and fixed on the reinforcing rod 24 through a connecting sleeve 525.

In this way, the extension rod 62 and the slide rail mechanism 61 are slidably connected, so that the dust removing member 63 can be driven to move up and down in front of the front frame 21 along the vertical direction, and the dust removing member 63 can perform dust removing operation on the display device body 200 arranged on the front frame 21.

The dust removing member 63 may be a brush, a dust removing cloth, or other structure that can wipe dust, and by way of example, referring to fig. 6, in some embodiments of the present application, the dust removing member 63 includes a dust removing roller brush 631 and a dust removing motor 632 for driving the dust removing roller brush 631 to rotate. Thus, when the dust removing member 63 slides along the extension rod 62 and the slide rail mechanism 61, the dust removing motor 632 can drive the dust removing roller brush 631 to rotate, and the dust removing roller brush 631 continuously rotates while moving up and down, so that dust on the display device body 200 can be effectively removed.

The sliding manner between the extension rod 62 and the slide rail mechanism 61 may be achieved by a single driving member, and the slide rail mechanism 61 is an electric slide rail slider mechanism, or the slide rail mechanism 61 is a linear cylinder, or the like, for example.

In order to realize automatic control, the display device stand 100 of the embodiment of the present application further includes a controller and a dumping detecting member, where the dumping detecting member is used for detecting whether the display device stand 100 is dumped, and the controller is used for controlling the plurality of buffer assemblies 3 to be in a complete state when the dumping detecting member detects that the display device stand 100 is dumped, so that the plurality of abutting members 31 and the frame 2 enclose a dumping avoidance space 4. In this way, the controller can ensure that the frame 2 is always kept in a complete state when toppling over, and can ensure that the impact force is buffered and the toppling avoidance space 4 is formed. Wherein, the toppling detecting piece can be a gyroscope or a displacement sensor and the like.

On this basis, in the scheme that the abutting piece 31 of the display equipment bracket 100 of the embodiment of the application can be switched between the first position and the second position, the controller can also automatically control the abutting piece 31 to be switched between the first position and the second position, and according to the dumping direction of the frame 2, the abutting piece 31 is controlled to extend towards the dumping side, so that the abutting piece 31 can be ensured to correctly buffer the dumping impact force.

Still further, when the display stand 100 of the embodiment of the present application includes the medium buffer mechanism 5, the controller is further configured to control the medium buffer mechanism 5 to operate to realize the buffering of the buffer bladder 53 when the dumping detection piece detects that the display stand 100 is dumped.

Again, where the display stand 100 of the present embodiment includes a dust removal mechanism 6, the controller may also be used to control the dust removal mechanism 6 to remove dust from the display body 200 disposed on the display stand 100.

The embodiment of the present application also provides a control method for controlling the working mode of the display device stand 100 in the above embodiment, specifically, the control method provided in the embodiment of the present application includes:

when the display device stand 100 is detected to topple over, the controller controls the plurality of buffer assemblies 3 to be in a complete state, so that the plurality of abutting pieces 31 and the frame 2 enclose a toppling avoidance space 4.

According to the control method, whether the display equipment support 100 is toppled or not can be accurately obtained by detecting the information of whether the display equipment support 100 is toppled or not, on the basis, if the display equipment support 100 is toppled, the plurality of buffer assemblies 3 are controlled to be in a complete state, the plurality of abutting pieces 31 and the frame 2 enclose a toppling avoidance space 4, and then the buffer posture is prepared, the abutting pieces 31 of the plurality of buffer assemblies 3 are ensured to contact the ground firstly when the display equipment support 100 is toppled, and damage to the display equipment body 200 due to toppling impact force is reduced; moreover, the plurality of abutting pieces 31 and the frame 2 enclose the dumping avoiding space 4, which can give people in the dumping range an avoiding area, and further reduce the injury to the people in the dumping range.

When the abutment 31 is located at the first position or the second position, the buffer assembly 3 is in a complete state, the first position is that the abutment 31 extends out of the rear frame 22, and the second position is that the abutment 31 extends out of the front frame 21, the control method of the embodiment of the present application may perform specific actions by detecting the direction of the display device stand 100 toward the dumping direction, for example: when the dumping direction is towards the front frame 21, the controller controls the abutting piece 31 to be located at the second position;

when the dumping direction is toward the rear frame 22, the controller controls the abutting piece 31 to be located at the first position.

In this embodiment, the abutment 31 may be located between the first position and the second position in the normal state, for example, in a central position between the first position and the second position.

However, in such a manner, if tilting occurs, it is necessary to control the operation of the abutment 31 regardless of the position of the abutment 31, and a certain time is required in this process.

when the dumping direction is toward the rear frame 22, the controller keeps the abutment 31 in the first position.

In this way, the abutment 31 is in the first position in the normal state, that is, in a complete state, when the dumping direction is toward the rear frame 22, the position of the abutment 31 is not adjusted, so that the operation process can be reduced, and the time can be saved.

Of course, in the above embodiment, if the tilting direction is tilting toward the front frame 21, the controller may take a long time to control the movement of the abutment 31 from the first position to the second position. Thus, in some embodiments, the control method further comprises:

the controller controls the abutting piece 31 to be located at the second position;

when the dumping direction is towards the front frame 21, the controller keeps the abutting piece 31 at the second position;

when the dumping direction is toward the rear frame 22, the controller controls the abutting piece 31 to move from the second position to the first position.
