DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0024] See also Figure 1 , Figure 2 and Figure 3The embodiment of the present application provides a multi-directional LED display screen support and storage device, including a base 1, a support arm 4, a ball head assembly 3 and a display assembly 2. The support arm 4 is arranged on the base 1, and the ball head assembly 3 includes a first matching portion 6, a second matching portion 7 and a ball head 11. The first matching portion 6 is connected to the support arm 4, and the first matching portion 6 and the second matching portion 7 are arranged opposite to each other along the first direction. The second matching portion 7 is rotatably connected to the first matching portion 6. Along the second direction, one side of the first matching portion 6 and the second matching portion 7 is respectively provided with an arc-shaped shell 9, and the two arc-shaped shells 9 surround a limiting cavity. The other side of the first matching portion 6 is provided with a supporting portion 8, and the supporting portion 8 is movably connected to the first matching portion 6 along the second direction. The other side of the second matching portion 7 is provided with a matching inclined surface 18, and the supporting portion 8 is against the matching inclined surface 18. The matching inclined surface 18 is configured so that when the supporting portion 8 moves in a direction away from the arc-shaped shell 9, the matching inclined surface 18 and the supporting portion 8 cooperate to close the two arc-shaped shells 9. The first direction is perpendicular to the second direction, and the ball head 11 is accommodated in the limiting cavity. The display assembly 2 is connected to the ball head 11 .

[0025] The display assembly 2 may include a display component, such as an LED display screen or other types of display components. The display assembly 2 may also include a support plate, the display component is mounted on the support plate, and the support plate is connected to the ball head 11.

[0026] The base 1 is used to install and set the display assembly 2, so that the position of the display assembly 2 is adjustable. For ease of use, the base 1 can be provided with running wheels.

[0027] The support arm 4 is used to support the display component 2. For example, the support arm 4 can be a mechanical arm. By setting the display component 2 on the mechanical arm, the position of the display component 2 on the base 1 can be adjusted. The mechanical arm can be selected from the existing structure and will not be repeated here.

[0028] The first direction can be Figure 3 The direction shown by the X axis, the second direction can be Figure 3 The direction shown by the Y axis.

[0029] The first direction, the second direction, and the rotation axes of the second matching portion 7 may be perpendicular to each other.

[0030] The limiting cavity surrounded by the arc-shaped shell 9 is used to accommodate the ball head 11, so that the ball head 11 can rotate in the limiting cavity, thereby allowing the position and orientation of the display assembly 2 connected to the ball head 11 to be adjusted.

[0031] The first matching portion 6 and the second matching portion 7 are arranged opposite to each other along the first direction, and the second matching portion 7 is rotatably connected to the first matching portion 6, so that the second matching portion 7 can have two states, one is that the two arc-shaped shells 9 are closed, at which time the two arc-shaped shells 9 can clamp the ball head 11, making it difficult for the ball head 11 to rotate relative to the limiting cavity, so that the ball head 11 can be locked. The other state is that the two arc-shaped shells 9 are separated, at which time the ball head 11 can be unlocked, that is, the ball head 11 can rotate relative to the limiting cavity.

[0032] The movable connection mode between the abutting portion 8 and the first matching portion 6 can be selected from the existing structures. For example, the first matching portion 6 can be provided with a slide rail, and the abutting portion 8 is connected to the first matching portion 6 via the slide rail.

[0033] A locking structure may be provided between the abutting portion 8 and the first matching portion 6, so that after the position of the abutting portion 8 is adjusted, the abutting portion 8 can be locked. The locking structure may be selected from existing structures, for example, the first matching portion 6 may be threadedly connected with a driving bolt, the axis of the driving bolt extends along the second direction, and the driving bolt is rotatably connected to the abutting portion 8, so that when the driving bolt rotates, the abutting portion 8 can be driven to move, and when the driving bolt stops rotating, the abutting portion 8 can be locked.

[0034] The abutting portion 8 cooperates with the matching slope 18 to switch the state of the second matching portion 7. That is, when the abutting portion 8 moves to the side away from the first matching portion 6 where the arc-shaped housing 9 is provided, the second matching portion 7 is pushed by the matching slope 18, so that the two arc-shaped housings 9 can be closed. On the contrary, when the abutting portion 8 moves to the side close to the first matching portion 6 where the arc-shaped housing 9 is provided, the two arc-shaped housings 9 can be separated.

[0035] The arrangement of the matching bevel 18 can be arranged according to actual conditions. For example, from the side where the second matching portion 7 is arranged on the arc-shaped shell 9 to the side away from the arc-shaped shell 9 , the matching bevel 18 can gradually approach the first matching portion 6 .

[0036] In the embodiment of the present application, on the one hand, a limiting cavity is formed by the arc-shaped shell 9 of the first matching portion 6 and the second matching portion 7, and the ball head 11 is accommodated in the limiting cavity, so that the position and orientation of the display component 2 can be adjusted. On the other hand, compared with the traditional one-piece ball head seat, the first matching portion 6 and the second matching portion 7 of the embodiment of the present application are easier to manufacture, which reduces the process difficulty, and at the same time, the replaceability is better, so the cost is lower. On the other hand, the clamping degree of the arc-shaped shell 9 on the ball head 11 is easy to adjust, so that the rotation resistance of the ball head 11 relative to the limiting cavity can also be adjusted as needed.

[0037] In the embodiment of the present application, when the abutting portion 8 moves in a direction away from the arc-shaped shell 9, the matching inclined surface 18 and the abutting portion 8 cooperate to close the two arc-shaped shells 9. On the one hand, such a setting has a wider adjustment range, thereby increasing the flexibility of adjusting the rotation resistance of the ball head 11 relative to the limiting cavity. On the other hand, when the abutting portion 8 gradually moves away from the arc-shaped shell 9, the abutting portion 8 can also gradually move away from the rotation axis of the second matching portion 7, so that the length of the force arm on the side of the first matching portion 6 and the second matching portion 7 away from the arc-shaped shell 9 increases, reducing the resistance to driving the abutting portion 8 to move.

[0038] See also Figure 3 In some embodiments, the arc-shaped shell 9 is movably provided with an extrusion portion 10, and the extrusion portion 10 is configured to squeeze the ball head 11 when moving toward the abutment portion 8, and the extrusion portion 10 is transmission-connected to the abutment portion 8.

[0039] The specific structure of the movably connected arc-shaped housing 9 and the extrusion part 10 can be selected from the existing structures, which will not be described in detail here. For example, the arc-shaped housing 9 can be provided with a slide groove 12, and the extrusion part 10 is slidably connected to the slide groove 12.

[0040] When the two squeezing parts 10 squeeze the ball head 11, the rotation resistance of the ball head 11 relative to the limiting cavity increases, thereby making it difficult for the ball head 11 to rotate relative to the limiting cavity.

[0041] The extrusion portion 10 is transmission-connected to the abutment portion 8, so that the extrusion portion 10 can be driven to move by the abutment portion 8, that is, the arc-shaped shell 9 clamps the ball head 11 and the extrusion portion 10 squeezes the ball head 11 simultaneously. The extrusion portion 10 further improves the locking effect of the ball head 11 and reduces the risk of displacement of the display component 2 when in the locked state.

[0042] See also Figure 3 and Figure 4 In some embodiments, the extrusion portion 10 moves along the arc length direction of the arc-shaped shell 9, and a flexible pad layer 19 is provided on the side of the extrusion portion 10 facing the ball head 11. Along the arc length direction of the arc-shaped shell 9, the thickness of the side of the flexible pad layer 19 away from the abutting portion 8 is greater than the thickness of the side close to the abutting portion 8.

[0043] For example, the arc length direction of the arc-shaped housing 9 can be Figure 3 The arc length direction of the arc-shaped profile of the arc-shaped shell 9 shown in FIG.

[0044] The extrusion portion 10 moves along the arc length direction of the arc-shaped shell 9, so that along the second direction, the extrusion portion 10 can gradually move from the side of the ball head 11 away from the abutment portion 8 along the outer wall surface of the ball head to the side of the ball head 11 close to the abutment portion 8.

[0045] The material of the flexible cushion layer 19 can be selected from existing materials, which will not be described in detail here.

[0046] The pressing portion 10 may be partially disposed on a side of the ball head 11 away from the abutting portion 8 .

[0047] The thickness of the side of the flexible cushion layer 19 away from the abutment portion 8 is greater than the thickness of the side close to the abutment portion 8, so that when the extrusion portion 10 moves in the direction away from the abutment portion 8, the extrusion force of the extrusion portion 10 on the ball head 11 gradually decreases. When the extrusion portion 10 moves in the direction close to the abutment portion 8, on the one hand, the extrusion portion 10 can press the ball head 11 to the side of the limiting cavity close to the abutment portion 8, and on the other hand, the extrusion portion 10 can squeeze the ball head 11 toward the middle, thereby increasing the locking effect of the extrusion portion 10 on the ball head 11.

[0048] See also Figure 3 In some embodiments, both ends of the transmission cable 13 are connected to the extrusion portion 10 , and the middle portion of the transmission cable 13 is connected to the abutment portion 8 .

[0049] The middle portion of the transmission cable 13 refers to a position between the two ends of the transmission cable 13 .

[0050] The abutting portion 8 may be provided with a hook-shaped structure, and the transmission cable 13 may be hooked to the hook-shaped structure, so that the transmission cable 13 can be connected to the abutting portion 8 .

[0051] The middle portion of the transmission cable 13 is connected to the abutting portion 8 , so that when the abutting portion 8 moves, the pressing portion 10 can be pulled to move by the transmission cable 13 .

[0052] In the embodiment of the present application, an elastic member, such as a spring, may be provided between the extrusion portion 10 and the arc-shaped housing 9 , and the elastic member is used to provide an elastic force for restoring the extrusion portion 10 in a direction away from the abutment portion 8 .

[0053] See also Figure 3 In some embodiments, the transmission cable 13 is bent to form two sections, the first matching portion 6 and the second matching portion 7 are respectively provided with a guide portion 17 , the two guide portions 17 are arranged between the two sections, and the middle portion of the transmission cable 13 is arranged between the two guide portions 17 .

[0054] The guide portion 17 may be a guide wheel rotatably disposed on the first matching portion 6 and the second matching portion 7 , or the first matching portion 6 and the second matching portion 7 may be respectively provided with an arc surface structure for the transmission cable 13 to contact.

[0055] Two guide parts 17 are arranged between the two sections, so that the transmission cable 13 can be stretched out through the two guide parts 17. On the one hand, when the transmission cable 13 is stretched out, it is convenient to connect the transmission cable 13 to the abutting part 8. On the other hand, when the arc-shaped shell 9 is closed, the side of the first matching part 6 where the abutting part 8 is arranged and the side of the second matching part 7 where the matching inclined surface 18 is arranged have a tendency to separate from each other, and thus the two guide parts 17 have a tendency to separate from each other, so that the travel of the transmission cable 13 pulling the extrusion part 10 to move is increased, and thus the locking effect of the extrusion part 10 on the ball head 11 is increased. On the other hand, when the abutting part 8 moves in the direction close to the arc-shaped shell 9, the transmission cable 13 makes the two guide parts 17 have a tendency to approach each other, that is, the transmission cable 13 facilitates the side of the first matching part 6 where the abutting part 8 is arranged and the side of the second matching part 7 where the matching inclined surface 18 is arranged to be closed.

[0056] See also Figure 3 In some embodiments, the second mating portion 7 is provided with a rotating portion 16, and the rotating portion 16 is provided with an arc-shaped slot 14. The opening of the arc-shaped slot 14 faces the side of the first mating portion 6 where the abutting portion 8 is provided. The first mating portion 6 is provided with an arc-shaped plate body 15. The arc-shaped plate body 15 is inserted into the arc-shaped slot 14 through the opening. The abutting portion 8 and the mating bevel 18 are configured so that when the abutting portion 8 abuts against the mating bevel 18, the abutting portion 8 and the mating bevel 18 cooperate to keep the arc-shaped plate body 15 inserted into the arc-shaped slot 14.

[0057] When the arc-shaped plate 15 is inserted into the arc-shaped slot 14 , the second matching portion 7 can rotate relative to the first matching portion 6 under the action of the arc-shaped slot 14 , thereby achieving the purpose of rotationally connecting the first matching portion 6 and the second matching portion 7 .

[0058] The opening of the arc slot 14 faces the side of the first matching portion 6 where the abutment portion 8 is set, reducing the risk of the arc plate 15 escaping from the arc slot 14 when the side of the first matching portion 6 where the abutment portion 8 is set and the side of the second matching portion 7 where the matching slope 18 is set are closed.

[0059] In the embodiment of the present application, the depth of the arc slot 14 and the length of the arc plate 15 can be reasonably set as needed to ensure that the relative rotation angle of the first matching portion 6 and the second matching portion 7 can meet the requirements, so that the arc plate 15 will not fall out of the arc slot 14 when the abutting portion 8 abuts against the matching inclined surface 18. For example, the position and relative proportion relationship of the arc slot 14 and the arc plate 15 can be as follows: Figure 3 shown.

[0060] When the abutting portion 8 abuts against the matching inclined surface 18 , the arc-shaped plate body 15 cannot escape from the arc-shaped slot 14 , so that the abutting portion 8 and the matching inclined surface 18 of the embodiment of the present application also play a role in limiting the first matching portion 6 and the second matching portion 7 .

[0061] The arc slot 14 cooperates with the arc plate 15, on the one hand, so that the first matching portion 6 and the second matching portion 7 have the advantage of being easy to disassemble and assemble. For example, when the abutting portion 8 moves in the direction close to the arc plate 15 until the abutting portion 8 is separated from the matching inclined surface 18, the matching inclined surface 18 can be further rotated toward the first matching portion 6, so that the arc plate 15 can be rotated out of the arc slot 14, and the first matching portion 6 and the second matching portion 7 can be disassembled. On the other hand, the arc slot 14 cooperates with the arc plate 15, and also plays a role in limiting the relative rotation angle of the first matching portion 6 and the second matching portion 7.

[0062] See also Figure 1 In some embodiments, the support arm 4 includes a plurality of arm segments 5 that are rotatably connected in sequence, wherein the arm segment 5 at the head end is rotatably connected to the base 1 , and the first matching portion 6 is connected to the arm segment 5 at the end.

[0063] The plurality of arm sections 5 are rotatably connected, and the arm section 5 at the head end is rotatably connected to the base 1 , which enables the support arm 4 to be deformed, thereby enabling the position of the display assembly 2 relative to the base 1 to be adjusted.

[0064] In some embodiments, a damping structure is provided between the arm section 5 and the base 1 , and between two adjacent arm sections 5 .

[0065] The damping structure is used to increase the resistance to rotation between the arm sections 5 , so that when no external force is applied to the support arm 4 , the support arm 4 can remain stationary, thereby providing a stable support for the display assembly 2 .

[0066] Furthermore, the support arm 4 may be provided with a locking component, and after the support arm 4 is adjusted, the arm section 5 is locked by the locking component, so that the arm section 5 cannot rotate, thereby increasing the supporting effect on the display assembly 2. The locking component can be selected from the existing structure, and will not be described in detail here.

[0067] See also Figure 1 In some embodiments, the base 1 is provided with a receiving cavity, and the arm section 5 is rotatably connected to the inner wall of the receiving cavity.

[0068] The arm section 5 is rotatably connected to the inner wall of the accommodation cavity, so that by reasonably setting the number of sections and the length of the arm section 5 , the display assembly 2 can be moved into or out of the accommodation cavity under the action of the support arm 4 .

[0069] See also Figure 1 In some embodiments, the base 1 is provided with a receiving cavity, and the support arm 4 is used to move the display assembly 2 into or out of the receiving cavity.

[0070] The accommodating cavity is used to protect the display assembly 2, that is, when the display assembly 2 is not in operation, it can be accommodated in the accommodating cavity, thereby reducing the risk of the display assembly 2 being impacted by the outside world.

[0071] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
