[0037] The existing TV base is equipped with foot pads, and the TV is supported by the span between the foot pads. However, due to the large size of the display device, the center of gravity of the display device is high, so the size of the base needs to be enlarged accordingly to meet the requirements of supporting the display device, thereby affecting the appearance of the display device. At the same time, under the influence of certain unexpected external forces, such as earthquakes, collisions, etc., the display device is in danger of tipping over. Therefore, a display device is proposed to solve the above problems.

[0038] The scheme is further illustrated by the following examples:

[0039] Figure 1 It is a schematic diagram of a display device according to an embodiment of the utility model placed on a supporting surface. Figure 2 yes Figure 1 Another schematic diagram of a display device placed on a support surface.

[0040] The display device provided in the embodiment of the utility model can be a television, a computer monitor, a display screen, etc. The support surface 6 can be a desktop or the ground, etc., for placing the display device. The following description is made by taking a television as an example.

[0041] See also Figure 1 and Figure 2 The display device may include a display body 100 and a support mechanism 10. The upper end of the support mechanism 10 is connected to the display body 100 to support the display body 100.

[0042] The display body 100 may include a display panel 1 and a rear case 3 .

[0043] The display panel 1 can be used as the front side wall of the display device. The display panel 1 can be constructed as a display screen on the front side of the display device, that is, the front side of the display panel 1 is a display surface for displaying image information for users to watch.

[0044] The display body 100 may further include a back plate (not shown in the figure).

[0045] The back plate may be disposed on the back side of the display panel 1, that is, the display panel 1 is disposed on the front side of the back plate. The back plate can be used to provide an installation space for the display panel 1 and provide structural support.

[0046] In some embodiments, a light guide plate (not shown in the figure), a diffusion plate (not shown in the figure) and a backlight source (not shown in the figure) etc. may be provided between the back surface of the display panel 1 and the back plate.

[0047] See also Figure 2 The rear shell 3 can be arranged on the back side of the back plate, and the rear shell 3 can completely cover the back side of the back plate to form the rear appearance surface of the display device.

[0051] Figure 3 yes Figure 1 A schematic structural diagram of an adsorbent and a base of a display device.

[0052] See also Figure 2 and Figure 3 The supporting mechanism 10 may include a suction member 20 , a closing component 30 and a base 40 .

[0053] Among them, the base 40 can be arranged at the lower end of the support mechanism 10 to support the support mechanism 10 and the display body 100. The base 40 can extend in the horizontal direction and be placed on the support surface 6. The adsorbent 20 can be fixed to the bottom of the base 40, and the adsorbent 20 can be adsorbed on the support surface 6 by negative pressure adsorption, so as to drive the base 40 to fit on the support surface 6, thereby enhancing the grip between the support mechanism 10 and the support surface 6, and preventing the display device from tipping over when affected by external force. The closing component 30 can be arranged on the base 40 and connected to the adsorbent 20, and is used to control the adsorbent 20 to fit on the support surface 6 or to control the adsorbent 20 to separate from the support surface 6.

[0054] See also Figure 2 The supporting mechanism 10 may further include a column 71 and a connecting plate 72 .

[0055] The column 71 can be fixed on the top of the base 40 , and the column 71 extends vertically. The connecting plate 72 is disposed on the column 71 to install the display main body 100 .

[0056] In this embodiment, the connecting plate 72 is connected to the rear housing 3 of the display body 100 to connect and support the display body 100 .

[0057] In some other embodiments, the connecting plate 72 may be connected to the bottom of the display body 100 , that is, connected to the lower frame of the display body 100 , so as to support the display body 100 .

[0058] See also Figure 3 A mounting portion 41 may be formed on the bottom surface of the base 40 .

[0059] The mounting portion 41 may be formed by being recessed upward from the bottom surface of the base 40 , and the adsorption member 20 may be mounted in the mounting portion 41 .

[0060] The bottom of the adsorbent 20 protrudes downward from the bottom surface of the base 40 so that the adsorbent 20 can be attached to and adsorbed on the support surface 6, thereby making the base 40 and the adsorbent 20 firmly attached to the support surface 6, preventing the base 40 and the adsorbent 20 from separating from the support surface 6 and causing the display device to tip over.

[0061] Figure 4 yes Figure 1 A schematic structural diagram of an adsorption member and an adsorption bracket of a display device. Figure 5 It is a schematic diagram of a cross-section of the base and the adsorbent. Figure 6 yes Figure 5 A partial enlarged view of . Figure 7 It is another schematic cross-sectional view of the base and the adsorbent.

[0062] See also Figure 3 , Figure 4 and Figure 5 , the adsorption member 20 can be fixed on the bottom of the base 40.

[0063] A concave groove 21 may be formed at the bottom of the adsorption member 20. The concave groove 21 is formed by being concave upward from the bottom surface of the adsorption member 20.

[0064] See also Figure 6 and Figure 7 The edges around the bottom surface of the concave groove 21 can be attached to the supporting surface 6 , so that a closed adsorption cavity 22 is formed between the concave groove 21 and the supporting surface 6 .

[0065] The adsorption component 20 can be made of a flexible material or an elastic material, so that the adsorption component 20 can be deformed. After the edges of the bottom surface of the adsorption component 20 are attached to the support surface 6, the adsorption component 20 can change the size of the adsorption cavity 22 by deformation, so that a negative pressure is formed in the adsorption cavity 22, and then the adsorption component 20 is tightly attached to the support surface 6 under the action of atmospheric pressure, thereby enhancing the grip between the support mechanism 10 and the support surface 6.

[0066] The adsorption member 20 may be made of flexible plastic, so that the adsorption member 20 can be attached to the support surface 6 by negative pressure.

[0067] See also Figure 3 , Figure 4 and Figure 6 The supporting mechanism 10 may further include an adsorption bracket 50 .

[0068] The adsorption bracket 50 can be fitted in the recessed groove 21 of the adsorption component 20, that is, the adsorption bracket 50 is installed in the recessed groove 21, and the bottom of the adsorption bracket 50 is higher than the bottom edge of the adsorption component 20, so that the adsorption component 20 is fitted on the support surface 6, and an adsorption cavity 22 can also be formed between the adsorption component 20 and the support surface 6.

[0069] The adsorption bracket 50 can be connected to the bottom of the base 40 by a fastener 51, so that the adsorption member 20 is fixed to the bottom of the base 40 through the adsorption bracket 50. Specifically, the adsorption member 20 is clamped between the top of the adsorption bracket 50 and the top side inside the mounting portion 41.

[0070] Since the adsorption member 20 is made of a flexible material, the adsorption member 20 is connected to the mounting portion 41 through the adsorption bracket 50 and the fastener 51 , so that the adsorption member 20 can be fastened to the base 40 to prevent the adsorption member 20 from being separated from the base 40 .

[0071] The adsorption bracket 50 is connected to the base 40 via a plurality of fasteners 51 , so that the adsorption bracket 50 and the adsorption member 20 are firmly connected to the base 40 .

[0072] In some other embodiments, the adsorption member 20 may also be directly bonded to the bottom of the base 40, or directly connected to the bottom of the base 40 via fasteners.

[0073] See also Figure 4 and Figure 6 A sealing gasket 60 may be provided around the edges of the bottom surface of the recessed groove 21 .

[0074] The sealing gasket 60 is arranged in an annular shape and matches the edges of the bottom surface of the concave groove 21. One side of the sealing gasket 60 can be sealed against the edges of the bottom surface of the concave groove 21, and the opposite side can be sealed against the support surface 6, so that a closed adsorption chamber 22 is formed between the concave groove 21 and the support surface 6.

[0075] The sealing gasket 60 may be a structure made of elastic material, so that the sealing gasket 60 can be attached to the support surface 6 with different roughness. Therefore, the adsorbent 20 is attached to the support surface 6 through the sealing gasket 60, so that the adsorbent 20 can be attached to different support surfaces 6, and the influence of the roughness of the support surface 6 on the sealing of the adsorption chamber 22 is avoided.

[0076] In addition, the sealing gasket 60 may have a certain degree of stickiness, so that the sealing gasket 60 can be directly bonded to the supporting surface 6 and avoid the influence on the sealing of the adsorption chamber 22 when there are holes on the supporting surface 6 .

[0077] See also Figure 3 and Figure 6 A vent hole 23 may be provided on the recessed groove 21 .

[0078] The vent hole 23 can communicate the adsorption chamber 22 with the outside of the adsorption member 20 to balance the pressure between the adsorption chamber 22 and the outside.

[0079] Since the adsorption bracket 50 is fitted in the concave groove 21 , the vent hole 23 can also pass through the adsorption bracket 50 at the same time, so that the vent hole 23 can be connected to the adsorption chamber 22 .

[0080] See also Figure 5 and Figure 6 The closing assembly 30 can be mounted on the base 40 to open or close the vent hole 23 .

[0081] Specifically, when the sealing component 30 opens the vent 23, the adsorption chamber 22 can be connected to the outside world, thereby balancing the air pressure in the adsorption chamber 22, facilitating the separation of the adsorption member 20 from the support surface 6, and further facilitating the movement of the display device. When the sealing component 30 closes the vent 23, the adsorption chamber 22 is disconnected from the outside world. When negative pressure is formed in the adsorption chamber 22, the adsorption member 20 can be attached to the support surface 6 under the action of atmospheric pressure, thereby driving the base 40 to be closely attached to the support surface 6, enhancing the grip between the support mechanism 10 and the support surface 6, and preventing the display device from tipping over due to external force.

[0082] Figure 8 It is a schematic diagram of the structure of the closing plug.

[0083] See Figure 6 for support surface. Figure 7 and Figure 8 , the closure assembly 30 may include a closure plug 35 .

[0084] One end of the closing plug 35 may be provided with a plunger 351. The plunger 351 may be detachably connected to the vent hole 23 to open or close the vent hole 23. That is, when the plunger 351 is connected to the vent hole 23, the plunger 351 can block the vent hole 23, so that the adsorption chamber 22 is disconnected from the outside world. Figure 6 When the plunger 351 is separated from the vent hole 23, the adsorption chamber 22 can communicate with the outside world through the vent hole 23, thereby balancing the air pressure of the adsorption chamber 22 and the outside world. Figure 7 shown.

[0085] The plunger 351 may be provided with a protrusion 352. The protrusion 352 is a flexible structure made of a flexible material, so that when the plunger 351 is connected in the vent hole 23, the protrusion 352 can close the vent hole 23.

[0086] The protrusion 352 can be set to be a flexible plastic. And the cross-sectional diameter of the protrusion 352 is larger than the aperture of the vent hole 23, so that when the protrusion 352 is located in the vent hole 23, the protrusion 352 and the vent hole 23 form an interference fit, that is, the protrusion 352 is blocked in the vent hole 23, and the vent hole 23 is closed to prevent the adsorption chamber 22 from being depressurized.

[0087] The end of the closing plug 35 relative to the plunger 351 may be provided with a movable portion 353. The closing plug 35 may be movably arranged on the base 40 through the movable portion 353, so that the closing plug 35 can move relative to the base 40 and the adsorbent 20, and further the closing plug 35 can drive the plunger 351 to open or close the vent 23.

[0088] Fig. 9 It is a schematic diagram of a cross-section of the adsorbent and the closure assembly. Fig.10 yes Fig. 9 A magnified view of point A. Fig.11This is a schematic diagram of the closed component enclosed in the vent hole

[0089] See also Fig. 9 , Fig.10 and Fig.11 The end of the vent hole 23 may be provided with a top ring 231. The top ring 231 is located at one end of the vent hole 23 away from the recessed groove 21. Specifically, the top ring 231 protrudes from the inner wall of the vent hole 23 and is arranged around the circumference.

[0090] In this embodiment, an annular protrusion structure is formed on the inner side wall of the vent hole 23 , and a top ring 231 is formed. The top ring 231 is an annular structure.

[0091] In another embodiment, the vent hole 23 expands outwardly along the radial direction of the vent hole 23 toward one end of the concave groove 21, so that a step structure is formed on the side of the vent hole 23 facing away from the concave groove, and the step structure is arranged circumferentially, and the step structure is a top ring 231. In some embodiments, the upper side wall of the concave groove 21 is concavely formed with a vent hole 23, and a through hole penetrating from top to bottom is opened on the upper part of the adsorption member 20, and the lower end of the through hole penetrates to the vent hole 23. The diameter of the through hole is smaller than the diameter of the vent hole, and a top ring 231 is formed between the through hole and the vent hole.

[0092] A through hole is provided in the middle of the abutting ring 231 so that the vent hole 23 can be provided through.

[0093] The closing assembly 30 may include a closing member 31 and an elastic member 32 .

[0094] The closing member 31 may be disposed in the vent hole 23. A first boss 311 may be disposed at one end of the closing member 31. The first boss 311 can abut against one end of the abutting ring 231 facing the recessed groove 21, that is, the first boss 311 can abut against the bottom of the abutting ring 231 to close the vent hole 23.

[0095] In some other embodiments, the first boss 311 may also abut against the connection between the vent hole 23 and the recessed groove 21 , that is, the end of the vent hole 23 facing the recessed groove 21 , so that the first boss 311 can close the vent hole 23 .

[0096] The elastic member 32 is connected between the closing member 31 and the base 40 to limit the first boss 311 to the bottom of the abutting ring 231. That is, the elastic member 32 can exert a force on the closing member 31 so that the first boss 311 abuts against the bottom of the abutting ring 231, thereby enabling the first boss 311 to close the vent hole 23 to prevent the adsorption chamber 22 from automatically releasing pressure. Fig.11 shown.

[0097] The elastic member 32 can be configured as a spring plate, a spring or elastic rubber, etc., to drive the first boss 311 to abut against the bottom of the abutting ring 231 .

[0098] At the same time, the closing member 31 can slide along the relative vent hole 23, so that the first boss 311 is separated from the abutting ring 231, so as to relieve the pressure of the adsorption chamber 22. When an external force is applied to the closing member 31, so that the closing member 31 overcomes the force applied to it by the elastic member 32, the closing member 31 can slide along the vent hole 23, and the first boss 311 is separated from the bottom of the abutting ring 231, so that the vent hole 23 can be opened, so that the adsorption chamber 22 is connected with the outside world, and the pressure difference between the adsorption chamber 22 and the outside world is balanced, such as Fig.10 shown.

[0099] See also Fig.10 and Fig.11 A second boss 312 may be provided at one end of the closing member 31 away from the first boss 311 , and a connecting column 313 may be formed between the second boss 312 and the first boss 311 .

[0100] Among them, the connecting column 313 can be inserted into the top ring 231, and the elastic member 32 is pressed between the side of the top ring 231 away from the recessed groove 21 and the second boss 312 to drive the closing member 31 to move in the direction away from the adsorption member 20, so that the first boss 311 is limited at the bottom of the top ring 231.

[0101] In some other embodiments, one end of the elastic member 32 can abut against the side of the abutting ring 231 away from the recessed groove 21 , and the other end can be directly connected to the connecting column 313 to drive the first boss 311 to abut against the bottom of the abutting ring 231 .

[0102] Fig.12 is an exploded view schematic of a closed assembly.

[0103] See also Fig.10 and 12 The closing component 30 may further include a key cover 33 and a key cap 34 .

[0104] The key cover 33 may be provided with a receiving cavity 331 and an air outlet 332. The air outlet 332 is connected to the receiving cavity 331. The key cover 33 is connected to the end of the vent hole 23 away from the recessed groove 21, that is, the key cover 33 is connected to the outer end of the abutting ring 231.

[0105] The end of the closing member 31 away from the first boss 311 is located in the accommodating cavity 331, and the key cap 34 is inserted into the air outlet 332. One end of the key cap 34 extends out of the air outlet 332, and the other end can abut against the end of the closing member 31 away from the first boss 311, so as to drive the closing member 31 to move along the axis of the vent 23 and open the vent 23. That is, the key cap 34 can drive the closing member 31 to move along the vent 23, so as to open the vent 23.

[0106] In this embodiment, the second boss 312 of the closing member 31 is accommodated in the accommodating cavity 331 , and the end of the key cap 34 can abut against the second boss 312 to drive the closing member 31 to move along the vent hole 23 , thereby opening the vent hole 23 .

[0107] See also Fig.11 and Fig.12 A third boss 341 is disposed at one end of the key cap 34 facing the closure member 31. Moreover, the diameter of the air outlet hole 332 is smaller than the diameter of the third boss 341, and the diameter of the accommodating cavity 331 is larger than the diameter of the third boss 341, so that the third boss 341 can be accommodated in the accommodating cavity 331 and is limited by the air outlet hole 332, so as to prevent the key cap 34 from being separated from the accommodating cavity 331.

[0108] In summary, the display body 100 is placed on the support surface 6 through the support mechanism 10, and the base 40 of the support mechanism 10 is installed with an adsorption member 20. The adsorption member 20 is provided with a recessed groove 21, and when the adsorption member 20 is attached to the support surface 6, the recessed groove 21 can form an adsorption cavity 22 with the support surface 6.

[0109] When the adsorption member 20 is pressed downward, causing the recessed groove 21 and the adsorption cavity 22 to deform, a negative pressure can be formed in the adsorption cavity 22. Under the action of atmospheric pressure, the adsorption member 20 is firmly attached to the support surface 6, and drives the base 40 to be tightly attached to the support surface 6, thereby preventing the display device from tipping over when affected by external force.

[0110] In addition, the adsorbent 20 is provided with a vent hole 23, and the vent hole 23 is connected to the recessed groove 21 and the adsorbent chamber 22. The closing component 30 is connected to the base 40, and can open or close the vent hole 23, thereby controlling the connection or disconnection of the vent hole 23, and further controlling the connection or disconnection between the adsorbent chamber 22 and the outside world.

[0111] Therefore, after placing the display device on the support surface 6, the sealing component 30 needs to be connected to the vent hole 23 to seal the vent hole 23. Then, the depression 21 and the adsorption cavity 22 are deformed by pressing, so that negative pressure is formed in the adsorption cavity 22, so that the adsorption member 20 is attached to the support surface 6, thereby preventing it from tipping over when affected by external force.

[0112] When the display device needs to be moved away from the supporting surface 6, it is only necessary to first detach the sealing component 30 from the vent hole 23, that is, open the vent hole 23 so that the air pressure in the adsorption chamber 22 is the same as the external air pressure, so that the adsorption component 20 is detached from the supporting surface 6, thereby facilitating the transportation of the display device.
