Detailed implementation manners

[0030] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] Combined with reference to Figures 1 to 8As shown, the utility model provides a top-mounted display device mounting structure, which includes: a first mounting seat 100; a rotating mechanism 200, which is rotatably connected to the first mounting seat 100, and the rotating mechanism 200 includes a connecting assembly, which is used to connect with the display device; a balancing mechanism 10, which includes a first balancing part 12, and the first balancing part 12 is connected to the rotating mechanism 200, and the first balancing part 12 abuts against the first mounting seat 100, and the abutting position of the first balancing part 12 and the first mounting seat 100 is a first position. When the top-mounted display device mounting structure is in a first usage state, the center of gravity of the rotating mechanism 200 on which the display device is installed is a first center of gravity, and along the radial direction of the rotation axis of the rotating mechanism 200, the first position and the first center of gravity are located on both sides of the rotation axis.

[0032] In this embodiment, the first mounting base 100 is fixedly connected to the ceiling, the rotating mechanism 200 is rotatably connected to the first mounting base 100, and the connecting assembly is used to connect to a display device (such as a television). When in use, the user can manually or use other tools to rotate the rotating mechanism 200 relative to the first mounting base 100, so that the connecting assembly drives the display device to rotate, thereby adjusting the angle of the display device. Figure 1 The figure shows the first usage state of the ceiling display device mounting structure, in which the user can view the content on the display device.

[0033] The balancing mechanism 10 is connected to the rotating mechanism 200 and can rotate with the rotating mechanism 200 relative to the first mounting seat 100. When the display device is connected to the connecting assembly, the rotating mechanism 200 and the display device form a new whole, whose center of gravity is the first center of gravity. Since the first center of gravity is not colinear with the rotation axis of the rotating mechanism 200 in the vertical direction, the rotating mechanism 200 equipped with the display device has a tendency to tilt relative to the first mounting seat 100 toward the side where the display device is located, that is, one side of the rotating mechanism 200 has a tendency to tilt up. The present application is provided with a balancing mechanism 10, and the first position and the first center of gravity are located on both sides of the rotation axis, that is, the force point of the abutting force between the first balancing part 12 and the first mounting seat 100 and the first center of gravity are located on both sides of the rotation axis. When the display device is connected to the connecting assembly, under the abutting force between the first balancing part 12 and the first mounting seat 100, the side of the rotating mechanism 200 that has a tendency to tilt up cannot tilt up, so that the rotation process of the rotating mechanism 200 is relatively stable. It can be seen from the above that the above arrangement can prevent the rotating mechanism 200 from tilting, ensure the stability of the overall structure, extend the service life of the installation structure, and at the same time improve the aesthetics of the overall structure, thereby enhancing the user experience.

[0034] In one embodiment of the present invention, the contact surface between the first balancing portion 12 and the first mounting seat 100 is an arc-shaped convex surface.

[0035] With the above settings, it is possible to save materials and reduce production costs on the premise of ensuring that the first balancing part 12 abuts against the first mounting seat 100.

[0036] In one embodiment, a groove adapted to the arc-shaped convex surface is provided on the bottom surface of the first mounting seat 100, which can increase the contact area between the two, thereby improving the abutting stability between the two.

[0037] Referring to Figures 1 to 8 As shown, the first balancing part 12 includes a rolling element 14, and the rolling element 14 can roll relative to the first mounting seat 100.

[0038] In this embodiment, the rolling element 14 abuts against the first mounting seat 100 and can roll relative to the first mounting seat 100. When the rotating mechanism 200 rotates relative to the first mounting seat 100, the friction between the first balancing part 12 and the first mounting seat 100 is rolling friction. Compared with sliding friction, the friction of rolling friction is smaller. Therefore, through the above settings, on the premise of preventing the rotating body from tilting, it is possible to ensure that the rotation process of the rotating mechanism 200 is smoother and improve the user experience.

[0039] Referring to Figures 1 to 8 As shown, in one embodiment of the present invention, when the first balancing part 12 includes a rolling element 14, the first mounting seat 100 includes a guiding structure 11, the guiding structure 11 includes a guiding groove 13, and the rolling element 14 is rollingly arranged in the guiding groove 13.

[0040] Through the above settings, it is possible to guide the rolling element 14.

[0041] In one embodiment, the rolling element 14 is a steel ball, an iron ball, etc.

[0042] Referring to Figures 1 to 8 As shown, in one embodiment of the present invention, the guiding structure 11 further includes an annular mounting frame 15, the guiding groove 13 is arranged on the annular mounting frame 15, and the annular mounting frame 15 is detachably connected to the first mounting seat 100.

[0043] In this embodiment, the guiding groove 13 is arranged at the bottom of the annular mounting frame 15. After long-term use, the guiding groove 13 may be worn or damaged. Since the annular mounting frame 15 is detachably connected to the first mounting seat 100, the annular mounting frame 15 can be replaced and repaired separately without replacing the entire mounting structure.

[0044] Referring to Figures 1 to 8As shown, in an embodiment of the present utility model, the annular mounting bracket 15 includes an inner ring 151, an outer ring 152, and a plurality of reinforcing ribs 153. The guiding groove 13 is annular and is disposed between the inner ring 151 and the outer ring 152. The plurality of reinforcing ribs 153 are arranged at intervals along the circumferential direction of the annular mounting bracket 15. The reinforcing ribs 153 are connected between the inner ring 151 and the outer ring 152 and can support the guiding groove 13.

[0045] In this embodiment, the guiding groove 13 is annular, so that it can guide the rolling element 14 in the circumferential direction of the annular mounting bracket 15. The arrangement of the plurality of reinforcing ribs 153 can not only improve the structural strength of the annular mounting bracket 15, but also support the guiding groove 13, reducing the probability of damage to the guiding groove 13 during the contact between the rolling element 14 and the guiding groove 13, thereby prolonging the service life of the annular mounting bracket 15.

[0046] Combined with reference to Figures 1 to 8 As shown, in an embodiment of the present utility model, when the first balancing portion 12 includes a rolling element 14, the first balancing portion 12 further includes a rolling element mounting seat 17. The rolling element mounting seat 17 is connected to the rotating mechanism 200. The rolling element 14 is spherical and is mounted on the rolling element mounting seat 17.

[0047] In this embodiment, the rolling element mounting seat 17 is connected to the rotating mechanism 200 and can rotate relative to the first mounting seat 100 along with the rotating mechanism 200. The rolling element 14 is mounted on the rolling element mounting seat 17 and can rotate at any angle relative to the rolling element mounting seat 17. Through the above arrangement, the installation of the rolling element 14 can be realized.

[0048] Combined with reference to Figures 1 to 9 As shown, in an embodiment of the present utility model, the balancing mechanism 10 further includes a second balancing portion 18. The first balancing portion 12 and the second balancing portion 18 are symmetrically arranged about the rotation axis. The second balancing portion 18 abuts against the first mounting seat 100. The abutting position of the second balancing portion 18 and the first mounting seat 100 is the second position. When the unfolding and folding mechanism 300 is in the second use state, the center of gravity of the rotating mechanism 200 equipped with the display device is the second center of gravity. Along the radial direction of the rotation axis of the rotating mechanism 200, the second position and the second center of gravity are located on both sides of the rotation axis.

[0049] In this embodiment, as Figure 9Shown is the second usage state of the installation structure of the ceiling-mounted display device. At this time, the connection component is turned up to a position parallel to the first mounting seat 100. When the installation structure of the ceiling-mounted display device is in the second usage state, the second position and the second center of gravity are on both sides of the rotation axis. That is to say, the acting point of the abutting force between the second balancing part 18 and the first mounting seat 100 and the second center of gravity are on both sides of the rotation axis. Since the second center of gravity and the rotation axis of the rotating mechanism 200 are not collinear in the vertical direction, the rotating mechanism 200 equipped with the display device has a tendency to tilt relative to the first mounting seat 100 towards the side where the display device is located, that is, one side of the rotating mechanism 200 has a tendency to lift. And in this application, the second balancing part 18 is provided. After the display device is connected to the connection component, under the abutting force between the second balancing part 18 and the first mounting seat 100, the side of the rotating mechanism 200 with the tendency to lift cannot lift upwards, thereby preventing the rotating mechanism 200 from tilting.

[0050] Combined with reference to Figures 1 to 8 As shown, in an embodiment of the present utility model, the second balancing part 18 includes a rolling member 14 and a rolling member mounting seat 17. The rolling member mounting seat 17 is connected to the rotating mechanism 200. The rolling member 14 is spherical. The rolling member 14 is mounted on the rolling member mounting seat 17, and the rolling member 14 abuts against the first mounting seat 100.

[0051] Combined with reference to Figures 1 to 8 As shown, in an embodiment of the present utility model, the connection component includes a deploying and retracting mechanism 300 and a second mounting seat 202. The second mounting seat 202 is rotatably connected to the first mounting seat 100. The deploying and retracting mechanism 300 has a deployed position and a retracted position. The deploying and retracting mechanism 300 includes a telescopic member and a movable arm 320 connected to each other. The movable arm 320 is rotatably connected to the second mounting seat 202. The movable arm 320 is used to connect to the display device. The telescopic member can drive the movable arm 320 to rotate relative to the second mounting seat 202, so that the deploying and retracting mechanism 300 switches between the deployed position and the retracted position. When the deploying and retracting mechanism 300 is in the deployed position, the installation structure of the ceiling-mounted display device is in the first usage state. When the deploying and retracting mechanism 300 is in the retracted position, the installation structure of the ceiling-mounted display device is in the second usage state.

[0052] In this embodiment, the rotating mechanism 200 can rotate around a vertical axis (i.e., the rotation axis extending along the Figure 1 vertical direction therein). As Figure 1 shown, when the deploying and retracting mechanism 300 is in the deployed position, the movable arm 320 is nearly perpendicular to the second mounting seat 202. As Figure 9 shown, when the deploying and retracting mechanism 300 is in the retracted position, the movable arm 320 is parallel to the bottom of the second mounting seat 202.

[0053] Specifically, the unfolding and folding mechanism 300 further includes a display device mounting bracket 400. The display device mounting bracket 400 is fixedly connected to the movable arm 320. The display device mounting bracket 400 includes a support frame 410 and two hanging arms 420. The support frame 410 is connected to the movable arm 320. The two hanging arms 420 are hung on the support frame 410. A plurality of mounting holes 421 are provided on both of the two hanging arms 420 for mounting a display device. The telescopic member is an electric push rod 310. One end of the electric push rod 310 is hinged to the second mounting seat 202, and the other end of the electric push rod 310 is hinged to the movable arm 320. The extension and shortening of the electric push rod 310 can adjust the angle between the movable arm 320 and the second mounting seat 202.

[0054] The unfolding and folding mechanism 300 further includes a fixed arm 330. One end of the fixed arm 330 is fixedly connected to the second mounting seat 202, and the other end of the fixed arm 330 is hinged to the end of the movable arm 320 away from the display device mounting bracket 400. The electric push rod 310 includes a driving end 311 and a movable end 312. The driving end 311 is a driving motor and is hinged to the bottom of the second mounting seat 202. The movable end 312 is hinged to the bottom end of the movable arm 320. The top end of the movable arm 320 is hinged to the bottom end of the fixed arm 330. When the driving end 311 drives the movable end 312 to extend, the electric push rod 310 and the movable arm 320 rotate away from the second mounting seat 202 respectively based on the hinge points at their respective tops, that is, open relative to the second mounting seat 202. When driving the movable end 312 to shorten, the electric push rod 310 and the movable arm 320 rotate towards the second mounting seat 202 respectively based on the hinge points at their respective tops, and can rotate to Figure 9 the position parallel to the bottom of the second mounting seat 202 as shown, achieving the purpose of storage.

[0055] With reference to Figures 1 to 8 As shown, in one embodiment, an arc-shaped groove 340 is provided on one of the fixed arm 330 and the movable arm 320, and a fixed pin 350 is provided on the other of the fixed arm 330 and the movable arm 320. During the rotation of the movable arm 320, the fixed pin 350 moves in the arc-shaped groove 340. The arc-shaped groove 340 defines the rotation stroke of the movable arm 320, improving the safety of the movable arm 320 during rotation.

[0056] With reference to Figures 1 to 8 As shown, in one embodiment of the present invention, the top-mounted display device mounting structure further includes a connection structure 20. The connection structure 20 is fixedly connected to the first mounting seat 100, and the rotation mechanism 200 is rotatably connected to the connection structure 20.

[0057] Through the above settings, the rotational connection between the rotation mechanism 200 and the first mounting seat 100 can be achieved.

[0058] With reference toFigures 1 to 8 As shown in Figures 1 to 8 , in an embodiment of the present utility model, the connection structure 20 includes a connection base 21. The connection base 21 is fixedly connected to the first mounting base 100. At least one rotation limiting structure 212 is provided on the connection base 21. The rotation mechanism 200 further includes a limiting member 201. The limiting member 201 and the rotation limiting structure 212 form a stop fit in the circumferential direction of the connection base 21.

[0059] Through the above arrangement, the rotation mechanism 200 can rotate a preset angle relative to the first mounting base 100.

[0060] As Figure 7 shown in Figure 7 , in an embodiment, the limiting member 201 is a screw. A semi-circular convex portion 214 is provided on the outer circumference of the connection base 21. Two end faces of the semi-circular convex portion 214 form two rotation limiting structures 212. When the limiting member 201 rotates with the rotation mechanism 200 to the positions where the two end faces are located, both end faces can stop the limiting member 201, thereby realizing the circumferential limiting of the rotation mechanism 200.

[0061] Referring to Figures 1 to 8 shown in Figures 1 to 8 , in an embodiment of the present utility model, the connection structure 20 further includes an anti-rotation piece 22. The connection base 21 has an installation cavity. The anti-rotation piece 22 is installed in the installation cavity, and the anti-rotation piece 22 forms a limit with the connection base 21 in the circumferential direction of the connection base 21.

[0062] Through the above arrangement, the installation of the anti-rotation piece 22 can be realized.

[0063] As Figure 7 shown in Figure 7 , in an embodiment, a plurality of convex columns 213 are provided on the inner wall of the installation cavity. The plurality of convex columns 213 are arranged at intervals along the circumference of the installation cavity. A plurality of bayonet holes 222 are provided on the anti-rotation piece 22. The plurality of bayonet holes 222 and the plurality of convex columns 213 are arranged in one-to-one correspondence. The convex columns 213 are clamped in the bayonet holes 222 corresponding to them. The setting of the convex columns 213 makes the anti-rotation piece 22 unable to rotate relative to the connection base 21.

[0064] Referring to Figures 1 to 8 shown in Figures 1 to 8 , in an embodiment of the present utility model, the rotation mechanism 200 further includes a rotating shaft 205 and a second mounting base 202. An anti-rotation hole 221 is provided on the anti-rotation piece 22. A first through hole 211 is further provided on the connection base 21. The anti-rotation hole 221 and the first through hole 211 are arranged corresponding to each other. The top-mounted display device mounting structure further includes a first connecting member 203. The first end of the rotating shaft 205 sequentially passes through the first through hole 211 and the anti-rotation hole 221, and forms a non-rotating fit with the anti-rotation hole 221. And the first end of the rotating shaft 205 is connected to the connection base 21 through the first connecting member 203. The second end of the rotating shaft 205 is rotatably connected to the second mounting base 202.

[0065] Through the above settings, the rotational connection between the second mounting base 202 and the first mounting base 100 can be achieved.

[0066] Referring to Figures 1 to 8 As shown in an embodiment of the present utility model, the rotating mechanism 200 further includes a mounting plate 2012, a bearing mount 207, two deep groove ball bearings 208, a support sleeve 209, a locking member 204, and a plain bearing 2011. A second through hole penetrating the rotating shaft 205 is provided on the rotating shaft 205. An anti-rotation hole 221 is provided on the anti-rotation piece 22. A first through hole 211 is provided on the connecting seat 21. A third through hole is provided on the mounting plate 2012, and the third through hole is correspondingly arranged with the first through hole 211. The mounting plate 2012 is fixedly mounted on the second mounting base 202. The bearing mount 207 is fixedly mounted at the bottom of the mounting plate 2012. The bearing mount 207 has an inner cavity. The two deep groove ball bearings 208 are sequentially arranged in the inner cavity of the bearing mount 207 in the vertical direction. One end of the rotating shaft 205 sequentially passes through the first through hole 211 and the anti-rotation hole 221 and forms a stop fit with the anti-rotation hole 221. The other end of the rotating shaft 205 passes through the third through hole and then penetrates into the inner cavity of the bearing mount 207. The two deep groove ball bearings 208 and the support sleeve 209 are both sleeved on the rotating shaft 205.
