[0002] At present, with the development of society, the use of audio-visual equipment such as monitors and tablet computers is becoming more and more popular. The appearance of these audio-visual equipment is mostly a plate-like structure. Due to its large size and heavy weight, it usually needs to be safely supported by a bracket for users to watch. In order to facilitate the movement of the existing bracket, a universal roller is set on the base. The movement or stop of the bracket on the support surface is supported by each roller. For example, the patent with announcement number CN217875118U discloses a monitor lift bracket, including a base and a column.

DETAILED DESCRIPTION

[0025] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings.

[0026] refer to Figures 1 to 6 A device support with a braking function includes a base 1, a column tube 2, a mounting member 3, a brake member 6 and a driving rod 7. The column tube 2 includes an upper column 21 and a lower column 22. A connecting member 19 is provided between the upper column 21 and the lower column 22. The two ends of the connecting member 19 are detachably connected to the upper column 21 and the lower column 22, respectively. The connecting member 19 is penetrated with a supporting hole 20 for sliding connection of the driving rod 7. The base 1 is penetrated with a movable hole 12 for installation of the lower column 22. The mounting member 3 is a plate-like structure and is provided with a mounting column 24. The mounting column 24 is provided with a locking sleeve 25 sleeved on the column tube 2. The locking sleeve 25 and the mounting column 24 are perpendicular to each other. The locking sleeve 25 has an opening, and the locking sleeve 25 can be expanded or tightened by screwing a bolt on the locking sleeve 25. The locking sleeve 25 is a prior art and will not be described in detail here. After the locking sleeve 25 is sleeved on the column tube 2, the height and azimuth position of the mounting member 3 relative to the column tube 2 can be relatively adjusted, and the position of the mounting column 24 on the column tube 2 can be locked or unlocked by a bolt. If any audio-visual device such as a monitor or a tablet computer is disassembled and installed on the mounting member 3, the user can loosen the locking sleeve 25 and rotate the mounting member 3 to adjust the azimuth angle of the audio-visual device, or adjust the height position of the mounting member 3 on the column tube 2 to adjust the height of the audio-visual device, so that the user can look at the display screen of the audio-visual device installed on the mounting member 3 at eye level.

[0027] The bottom surface of the base 1 is surrounded by a plurality of universal rolling members 5, which are, for example, universal casters and can rotate 360° horizontally. The bottom surface of the base 1 is formed with a mounting cavity 4 for mounting the universal rolling member 5, so that the bottom of the universal rolling member 5 is exposed from the mounting cavity 4 and contacts the supporting surface, so that the base 1 can be rotatably or movably arranged on the supporting surface.

[0028] The brake member 6 is connected to the bottom end of the driving rod 7, and the driving rod 7 is inserted into the column tube 2. The column tube 2 is provided with a gear adjustment mechanism 8 connected to the top of the driving rod 7. The brake member 6 is controlled by the gear adjustment mechanism 8 to extend or retract relative to the bottom surface of the base 1, so that the brake member 6 has a braking state and a released state.

[0029] In the braking state, the brake member 6 extends out of the base 1 and contacts the support surface to interfere with the displacement movement of the base 1 relative to the support surface through the friction between the brake member 6 and the support surface. The base 1 is rotatably arranged around the brake member 6.

[0030] In the brake-released state, the brake member 6 is separated from the support surface, and the base 1 is arranged to rotate or move relative to the support surface.

[0031] When the distance between the bracket and the user reaches a suitable distance, the user links the brake member 6 through the gear adjustment mechanism 8 to extend it out of the base 1 and contact the support surface to brake the bracket. The brake member 6 is arranged below the column tube 2 to better utilize the weight of the audio-visual equipment and the bracket to brake the bracket. The bottom end of the driving rod 7 is provided with a bearing member 10 so that the brake member 6 can rotate in the column tube 2. The bearing member 10 is used to assist in supporting the brake member 6, reduce the friction coefficient during its rotation, and ensure its rotation accuracy. The bearing member 10 is a prior art and will not be described in detail here. The setting of the bearing member 10 allows the base 1 to flexibly rotate around the brake member 6 as the center when the bracket is in the centering braking state, which can avoid the friction between the brake member 6 and the support surface from interfering with the centering rotation of the bracket to a certain extent, so that the user can adjust the azimuth angle of the display and ensure that the distance between the display and the user is maintained within a suitable distance when adjusting its azimuth angle, thereby improving the user experience.

[0032] Of course, in other embodiments, it is also feasible to not provide the bearing member 10 and only provide the brake member 6 below the column tube 2 to better utilize the weight of the audio-visual equipment and the bracket to enhance the braking effect.

[0033] The brake member 6 includes a rubber block 61 and a first elastic member 62 . The bearing member 10 is provided with a telescopic mechanism 11 . The first elastic member 62 is arranged in the telescopic mechanism 11 and connected to the rubber block 61 .

[0034] The telescopic mechanism 11 includes a mounting frame 111, a guide column 112 and a mounting shell 113. The mounting frame 111 is connected to the bearing member 10. The mounting frame 111 is penetrated with a through hole 13. The top end of the guide column 112 is slidably connected in the through hole 13. The bottom end of the guide column 112 is connected to the mounting shell 113. The rubber block 61 is arranged at the bottom of the mounting shell 113 and is inserted and moved in the movable hole 12. The first elastic member 62 is a spring structure. The first elastic member 62 is arranged between the mounting frame 111 and the mounting shell 113 and is sleeved on the guide column 112. The end of the guide column 112 exposed from the through hole 13 is provided with a limiting member 14. The limiting member 14 is a columnar structure and is plugged into the guide column 112 to limit the position of the guide column 112 from the through hole 13.

[0035] The gear adjustment mechanism 8 includes a rotating handle 81 and a connecting end cover 82. The rotating handle 81 is rotatably connected to the connecting end cover 82. The connecting end cover 82 is arranged on the top of the column tube 2. The connecting end cover 82 is penetrated by a driving hole 9. The top end of the driving rod 7 is arranged on the rotating handle 81 and is threadedly connected to the driving hole 9.

[0036] The driving rod 7 includes a screw rod 71, an upper shaft rod 72 and a lower shaft rod 73. The screw rod 71 is threadedly connected to the driving hole 9. The bottom end of the lower shaft rod 73 is connected to the brake member 6. A coupling 23 is provided between the screw rod 71 and the upper shaft rod 72, and between the upper shaft rod 72 and the lower shaft rod 73 to form the driving rod 7. The coupling 23 between the upper shaft rod 72 and the lower shaft rod 73 is located in the lower column 22. When the user rotates the rotary handle 81, the screw rod 71 and the driving rod 7 are threadedly connected to drive the driving rod 7 to move up and down along its axis, thereby driving the mounting shell 113 to slide in the movable hole 12, so that the rubber block 61 contacts or separates from the supporting surface. The guide column 112 is used to guide the telescopic activity of the first elastic member 62. When the rubber block 61 contacts the supporting surface, the first elastic member 62 is deformed under pressure, and cooperates with the guide column to guide the first elastic member 62 to strengthen the tightness of the rubber block 61 to the supporting surface. In addition, by setting the wire diameter and height of the spring serving as the first elastic member 62 , the longitudinal dimension deviation of the rubber block 61 can be compensated and the appropriate braking force of the rubber block 61 on the supporting surface can be controlled.

[0037] The connecting end cover 82 is formed with a gear cavity 15 for the rotating handle 81 to move. The cross section of the gear cavity 15 is wavy ring-shaped. The rotating handle 81 is symmetrically provided with two mounting tubes 16. A gear member 17 is slidably connected in the mounting tube 16. A second elastic member 18 is provided between the mounting tube 16 and the gear member 17 so that the gear member 17 extends out of the mounting tube 16 and contacts with the inner concave part or the outer convex part of the gear cavity 15. The gear member 17 is a spherical structure, and the second elastic member 18 is a spring structure. When the user rotates the rotating handle 81, the outer curved surface of the gear member 17 contacts the gear. The inner wall of the cavity 15 remains in contact and moves along the rotation direction of the rotating handle 81 until the user stops rotating the rotating handle 81. The gear member 17, under the action of the second elastic member 18, disengages from the outer convex portion in the gear cavity 15 and contacts the inner concave portion in the gear cavity 15, thereby realizing the gear adjustment of the telescopic activity of the driving rod 7 by rotating the gear adjustment mechanism 8 and the self-locking effect of the rotating handle 81 after the telescopic rod is adjusted, so that the user can more accurately adjust the friction force of the rubber block 61 on the supporting surface, making the braking operation and the release operation of the bracket more convenient.

[0038] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
