[0047] In the embodiment of the present application, by providing a connecting arm 200 to connect the mounting member 100 and the display carrier base 300, the display carrier base 300 can be movable relative to the mounting member 100, facilitating the adjustment of the position of the display. The display carrier base 300 having a connecting head 310, a rotational connection assembly 320, and a mounting base 330 enables the display mounted on the mounting base 330 to adjust the angle and orientation, which helps to improve the adjustability of the display bracket for the use of the display bracket.

[0048] In one embodiment, a monitor bracket is disclosed. Please refer to Figures 1 - 10 , the monitor bracket includes a mounting member 100, a connecting arm 200, and a monitor carrier 300 that are connected in sequence. The mounting member 100 is used to be fixed on a mounting base, and the monitor carrier 300 is used to mount a monitor.

[0049] The mounting member 100 is used to fix the monitor bracket on the mounting base. In different embodiments, according to the different mounting bases in the application scenario, the mounting member 100 can have various setting forms. For example:

[0050] If the mounting base is a support rod or column on a director's vehicle, the mounting member 100 can be a pipe clamp. Exemplarily, please refer to Figure 1 , the pipe clamp is integrally provided at one end of the connecting arm 200. The pipe clamp includes a fixing part 110, a movable part 120, and a clamping wrench 130. One end of the movable part 120 is hinged to the fixing part 110, and the other end of the movable part 120, as a movable end, is connected to the fixing part 110 through the clamping wrench 130. The movable part 120 and the fixing part 110 jointly enclose a clamping cavity 140. After passing the support rod or column through the clamping cavity 140, the movable part 120 is locked by adjusting the clamping wrench 130, so that the support rod or column is clamped in the clamping cavity 140, that is, the clamping installation is completed. In other embodiments, pipe clamps of other structural forms can also be used, and the pipe clamp can also adopt a split structure with the connecting arm 200, as long as it can be fixed on the connecting arm 200.

[0051] If the mounting base is a desktop or a board surface, the mounting member 100 can be a desktop clamp. Exemplarily, please refer to Figure 2 , if there are mounting holes on the desktop or board surface, the mounting member 100 can adopt a perforated installation type desktop clamp 150, that is, the desktop clamp includes a perforated column and two clamping and locking members 3331 provided on the perforated column. After passing the perforated column through the perforation on the desktop or board surface, and then adjusting the clamping and locking members 3331 to clamp the desktop or board surface in the middle, the installation and fixation of the mounting member 100 can be completed. Please refer to Figure 3 , if it needs to be installed at the edge of the desktop or board surface, the mounting member 100 can select a side clamping installation type desktop clamp 160 with a clamping mouth, that is, the desktop clamp includes a C-shaped clamping member. A clamping mouth is formed on one side of the C-shaped clamping member, and a set screw is provided on one side or both sides of the C-shaped clamping member on the side of the clamping mouth. When in use, the clamping mouth is clamped on the edge of the desktop or board surface, and the set screw is adjusted to clamp the desktop or board surface in the clamping mouth.

[0052] Please refer to Figure 4, the connecting arm 200 is connected to the mounting member 100. The connecting arm 200 includes at least one main arm 210. When the connecting arm 200 includes at least two main arms 210, the main arms 210 are sequentially movably connected. By increasing the number of main arms 210, the range of motion and degrees of freedom of the display carrier 300 can be improved, further enhancing the adjustability of the display bracket. Exemplarily, the connecting arm 200 includes two main arms 210, which are rotatably connected between them. The mounting member 100 and the display carrier 300 are respectively arranged at the ends of the two main arms 210 away from each other.

[0053] In other examples, the number of main arms 210 can also be set to one, three, four, etc. as needed. The axes of rotation between the main arms 210 can be parallel, perpendicular, or staggered, and can be flexibly selected according to actual needs.

[0054] In one embodiment, please refer to Figure 5 , on one of the two rotatably connected main arms 210, there is a rotating connection shaft 230, and on the other, there is a shaft hole 214. The rotating connection shaft 230 passes through the shaft hole 214 to enable the two main arms 210 to be rotatably connected; a fifth bushing 231 is sleeved on the rotating connection shaft 230, and at least part of the fifth bushing 231 is clamped between the two main arms 210 to exert damping, so that the rotation between the two main arms 210 has a damping effect.

[0055] Please refer to Figure 4 and Figure 5 , the display carrier 300 includes a connection head 310, a rotating connection assembly 320, and a mounting base 330. The connection head 310 is movably connected to the end of the connecting arm 200 away from the mounting member 100. The rotating connection assembly 320 is rotatably connected to the connection head 310 around a first axis of rotation. The mounting base 330 is rotatably mounted on the rotating connection assembly 320 around a second axis of rotation. The mounting base 330 is used to mount the display. In some embodiments, the first axis of rotation and the second axis of rotation are staggered. For example, the first axis of rotation and the second axis of rotation are perpendicular or substantially perpendicular. The setting of the rotating connection assembly 320 enables the mounting base 330 to rotate relative to the connection head 310 around the first axis of rotation and the second axis of rotation, which helps to increase the degrees of freedom of the mounting base 330 and further enhances the adjustability of the display bracket.

[0056] In one embodiment, please refer to Figure 5, the connecting head 310 is rotatably connected to the connecting arm 200. Among them, the connecting head 310 has a shaft-passing hole 311, and the connecting arm 200 further includes an adjusting shaft 220. One end of the adjusting shaft 220 is provided with a positioning protrusion 313. The other end of the adjusting shaft 220 passes through the shaft-passing hole 311 and is threadedly connected to the main body arm 210. A third bushing 312 is sleeved on the adjusting shaft 220. The third bushing 312 includes a sleeve body part 3121 located inside the shaft-passing hole 311 and a damping part 3122 located outside the shaft-passing hole 311. The damping part 3122 is clamped between the main body arm 210 and the connecting head 310. In some embodiments, the axis of the shaft-passing hole 311 is perpendicular or substantially perpendicular to both the first rotation axis and the second rotation axis, which helps to further improve the adjustability of the monitor bracket. By cooperating the positioning protrusion 313 with the third bushing 312, a damping effect is provided for the relative rotation of the connecting head 310 and the connecting arm 200, which helps the connecting head 310 to be fixed at a required angle relative to the connecting arm 200.

[0057] In a further embodiment, please refer to Figure 5 , a bearing 314 and a fourth bushing 317 are sleeved on the adjusting shaft 220. The bearing 314 and the fourth bushing 317 are clamped between the positioning protrusion 313 and the connecting head 310, and the fourth bushing 317 is located on the side of the bearing 314 away from the positioning protrusion 313. The bearing 314 can assist in fixing the adjusting shaft 220. The setting of the fourth bushing 317 can increase the rotation feel, and the cooperation of the bearing 314 and the fourth bushing 317 helps to prevent the adjusting shaft 220 from loosening during use.

[0058] Exemplarily, please refer to Figure 5 , the main body arm 210 bifurcates to form two branch arms 211. The two branch arms 211 are arranged in parallel. One side of the connecting head 310 is clamped between the two branch arms 211. The shaft-passing hole 311 is arranged on the part of the connecting head 310 clamped between the two branch arms 211. A threaded through hole 212 is correspondingly arranged on one branch arm 211 opposite to the shaft-passing hole 311, and an adjusting through hole 213 is correspondingly arranged on the other branch arm 211 opposite to the shaft-passing hole 311. The end of the shaft-passing hole 311 opposite to the threaded through hole 212 is coaxially enlarged in diameter to form a step surface. The two third bushings 312 are both arranged in a stepped shape. The third bushing 312 is embedded in the end of the shaft-passing hole 311 where the step surface is formed. The damping part 3122 of the third bushing 312 is clamped between the step surface and the branch arm 211, so that one side of the damping part 3122 abuts against the main body arm 210 and the other side abuts against the connecting head 310 to exert a damping effect when the connecting head 310 and the main body arm 210 rotate relatively; the fourth bushing 317 is clamped at the end of the shaft-passing hole 311 away from the step surface. The fourth bushing 317 is partially clamped in the shaft-passing hole 311 and partially extends into the adjusting through hole 213.

[0059] A bearing 314 is also provided in the adjusting through hole 213. The bearing 314 can be a plane bearing 314. One side of the plane bearing 314 is arranged close to the fourth sleeve 317, and the other side is provided for the positioning protrusion 313 to abut. The end of the adjusting shaft 220 away from the positioning protrusion 313 has a thread for cooperating with the threaded through hole 212. During installation, the end of the adjusting shaft 220 away from the positioning protrusion 313 is passed through the bearing 314, the fourth sleeve 317, the shaft hole 311, and the third sleeve 312 in sequence, and screwed into the threaded through hole 212 until the positioning protrusion 313 and the bearing 314 are tightly pressed to the required degree, that is, the installation is completed. By adjusting the tightness of the positioning protrusion 313 and the bearing 314, the rotation damping degree between the connector 310 and the main arm 210 can be adjusted. In order to facilitate the adjustment of the tightness of the adjusting shaft 220, a hexagonal groove can also be provided on the positioning protrusion 313 so that it can be screwed with a hexagonal wrench.

[0060] In other embodiments, the connecting head 310 may also be disposed only on one side of the main arm 210 , and other structures may be used to realize rotational connection between the connecting head 310 and the main arm 210 and between the main arms 210 .

[0061] In addition, in a specific embodiment, please refer to Figure 5 The rotation connection structure between each main body arm 210 can be the same as the rotation connection structure between the main body arm 210 and the connector 310, so that the rotation damping degree of each rotation connection can be adjusted in the same way during use. Of course, other rotation connection structures can also be used between each main body arm 210.

[0062] In one embodiment, please refer to Figure 6 and Figure 7, the rotating connection assembly 320 includes a connection body 321, and the connection body 321 is rotatably connected to the connection head 310. Among them, the connection body 321 has a connection hole 3211, and a second bushing 3212 is provided in the connection hole 3211; an expansion sleeve 315 is provided on the connection head 310. The expansion sleeve 315 has an expansion end 3151 and a fixed end 3152. The fixed end 3152 of the expansion sleeve 315 is connected to the connection head 310, and the expansion end 3151 of the expansion sleeve 315 is inserted into the inner cavity of the second bushing 3212. The inner wall of the expansion sleeve 315 has an inclined surface 3154 on one side close to the expansion end 3151. An adjusting column 316 is movably arranged in the expansion sleeve 315. The adjusting column 316 can axially push against the inclined surface 3154 along the expansion sleeve 315, so that the expansion end 3151 of the expansion sleeve 315 opens to abut against the inner wall of the inner cavity of the second bushing 3212. By controlling the displacement of the adjusting column 316, the opening and closing degree of the expansion end 3151 of the expansion sleeve 315 can be adjusted, and further the tightening degree between the expansion end 3151 of the expansion sleeve 315 and the second bushing 3212 can be changed, so as to achieve the effect of adjusting the rotational damping degree between the connection head 310 and the connection body 321. In some specific embodiments, the material of the second bushing 3212 can be a wear-resistant material, such as engineering plastic, to improve the wear resistance performance.

[0063] In some embodiments, a conical surface 3161 can also be provided at one end of the adjusting column 316 close to the expansion end 3151 of the expansion sleeve 315. The conical surface 3161 is correspondingly arranged with the inclined surface 3154, so that the adjusting column 316 can make the expansion end 3151 open by pushing against the inclined surface 3154.

[0064] Exemplarily, please refer to Figure 6 and Figure 7 , the connection head 310 is set as a Y-shaped structure with two bifurcations on one side. One end of the connection body 321 rotatably connected to the connection head 310 is inserted between the two bifurcations of the connection head 310. Two expansion sleeves 315 are provided. The expansion ends 3151 of the two expansion sleeves 315 respectively penetrate through the part of the connection head 310 on one side of the connection body 321 and extend into the second bushing 3212. A ring-shaped boss 3153 is integrally provided at the fixed end 3152 of the expansion sleeve 315. The ring-shaped boss 3153 is fixed to the connection head 310 by a fastener, so that the expansion sleeve 315 is fixed on the connection head 310. One end of the adjusting column 316 with the conical surface 3161 is threadedly connected in the expansion sleeve 315 and is close to the expansion end 3151, so that the conical surface 3161 corresponds to the inclined surface 3154, so as to adjust the opening and closing degree of the expansion end 3151 by screwing the adjusting column 316. In some embodiments, the adjusting column 316 can be a machine screw. A hexagonal groove can also be provided on one side of the adjusting column 316 close to the fixed end 3152 of the expansion sleeve 315, so as to use a hexagonal wrench to adjust the adjusting column 316.

[0065] In other embodiments, the connector 310 may also adopt other shape structures, and other rotational connection structures may also be adopted between the connection body 321 and the connector 310, as long as the rotational connection between the rotational connection assembly 320 and the connector 310 can be achieved.

[0066] In one embodiment, please refer to Figure 7 and Figure 8 , the rotational connection assembly 320 further includes a rotational fitting 322. The rotational fitting 322 is connected to the connection body 321 and is movably clamped to the mounting base 330, so that the connection body 321 can rotate relative to the mounting base 330 about the second rotational axis.

[0067] In one embodiment, one side of the mounting base 330 close to the connection body 321 has a limiting hole; the connection body 321 has a sleeve portion 3213, and the sleeve portion 3213 is inserted into the limiting hole, so that the connection body 321 and the mounting base 330 are rotationally fitted; one end of the rotational fitting 322 is connected to the sleeve portion 3213, and the other end of the rotational fitting 322 is movably inserted into the limiting hole along the second rotational axis, so that the rotational fitting 322 is movably clamped to the mounting base 330. Under the connection of the rotational fitting 322, the mounting base 330 can rotate relative to the connection body 321.

[0068] In some embodiments, the limiting hole is a stepped hole 3321, and the sleeve portion 3213 is inserted into the stepped hole 3321. The so-called stepped hole 3321 refers to a reduced-diameter hole with a stepped hole wall and a stepped surface; the stepped surface of the stepped hole 3321 faces away from the connection body 321. One end of the rotational fitting 322 inserted into the stepped hole 3321 has a resisting limiting surface 3221, and the resisting limiting surface 3221 is used to resist against the stepped surface of the stepped hole 3321. In some other embodiments, the limiting hole may also be a tapered hole or other holes that can accommodate the movable insertion of the rotational fitting 322.
