[0024] See also Figures 1 to 4 , Figure 1 It is a schematic diagram of the three-dimensional structure of the display device mounting bracket when the support base 10 is in the first position according to an embodiment of the present invention; Figure 2 It is a schematic diagram of the three-dimensional structure of the display device mounting bracket when the support base 10 is in the second position according to an embodiment of the present invention; Figure 3 yes Figure 1 A schematic diagram of a three-dimensional structure of a partial structure of a display device mounting bracket in a disassembled state; Figure 4 yes Figure 1 A schematic diagram of a three-dimensional structure of a partial structure of a display device mounting bracket in a disassembled state from another perspective. An embodiment of the present invention provides a display device rotating bracket 100, and the display device rotating bracket 100 includes a support seat 10, a lifting mechanism 20, a mounting assembly 30 and a buffer structure 40. The support seat 10 is provided with an arc-shaped slide groove 101. The lifting mechanism 20 is slidably connected to the support seat 10 in the vertical direction. The mounting assembly 30 includes a mounting seat 31, a rotating shaft 32 and a sliding block 33. The mounting seat 31 is rotatably connected to the lifting mechanism 20 through the rotating shaft 32, and is used to install the display device. The sliding block 33 is arranged on the mounting seat 31 and slidably cooperates with the arc-shaped slide groove 101. The buffer structure 40 is arranged on the support seat 10 and is connected to the lifting mechanism 20, and the buffer structure 40 applies an elastic force upward in the vertical direction to the lifting mechanism 20.

[0025] In this embodiment, when the mounting seat 31 rotates relative to the lifting mechanism 20 to switch between the first position and the second position, the sliding block 33 slides from one end of the arc-shaped sliding groove 101 to the other end, and the rotating shaft 32 drives the lifting mechanism 20 to slide upward and then downward relative to the support seat 10.

[0026] It should be noted that the vertical direction in the present application is defined based on the observation direction of the plane on which the display device is installed on the vertical mounting base 31. The vertical direction refers to the direction parallel to the plane on which the display device is installed on the mounting base 31 and located in the vertical plane.

[0027] Specifically, the support base 10 can be set on a support surface such as a desktop or a wall to support the weight of other components and the display device. In this embodiment, the support base 10 includes a bottom plate 11 and a shell 12. The bottom plate 11 is used to be set on a horizontal support surface such as a desktop. The lifting mechanism 20 and the buffer structure 40 are installed in the shell 12. The shell 12 is hinged to the bottom plate 11. The shell 12 can drive the lifting mechanism 20 and the mounting assembly 30 to rotate around the horizontal axis relative to the bottom plate 11 to adjust the pitch angle of the display device.

[0028] Specifically, the lifting mechanism 20 can be slidably connected to the support base 10 by means of balls, rollers, guide grooves, etc., and the lifting mechanism 20 can slide relative to the support base 10 in the vertical direction.

[0029] In this embodiment, one end of the rotating shaft 32 is rotatably matched with the mounting seat 31, and the other end of the rotating shaft 32 is fixedly connected to the lifting mechanism 20, so that the mounting seat 31 can rotate relative to the lifting mechanism 20. In other embodiments, the rotating shaft 32 can also be configured so that one end is fixedly connected to the mounting seat 31 and the other end is rotatably matched with the lifting mechanism 20; or, the two ends of the rotating shaft 32 are rotatably matched with the mounting seat 31 and the lifting mechanism 20 respectively, so that the mounting seat 31 can rotate relative to the lifting mechanism 20.

[0030] In this embodiment, the sliding block 33 is fixed to the side of the mounting seat 31 facing the support seat 10 and is engaged in the arcuate slot 101. When the mounting seat 31 rotates relative to the lifting mechanism 20, the sliding block 33 slides along the arcuate slot 101 and rotates in the arcuate slot 101 at the same time.

[0031] In this embodiment, the buffer structure 40 is mounted and fixed on the support seat 10 and is located on the top side of the lifting mechanism 20. The buffer structure 40 provides an upward elastic pulling force for the lifting mechanism 20. In other embodiments, the buffer structure 40 may also be located on the bottom side of the lifting mechanism 20. The buffer structure 40 provides an upward elastic thrust for the lifting mechanism 20.

[0032] In this embodiment, the buffer structure 40 is configured as a constant force spring to provide a stable elastic force to the lifting mechanism 20, which helps the lifting mechanism 20 to rise and fall smoothly, thereby improving the stability of the mounting seat 31 when it is rotated up and down. In other embodiments, the buffer structure 40 can also be configured as a tension spring, a leaf spring, or other devices.

[0033] In this embodiment, when the mounting seat 31 is in the first position, the display device is in a horizontal screen state, and the sliding block 33 is located at one end of the arc-shaped slide groove 101. When the mounting seat 31 is in the second position, the display device is a vertical screen device, and the sliding block 33 is located at the other end of the arc-shaped slide groove 101. During the process of the mounting seat 31 rotating from the first position to the second position and from the second position to the first position, the rotating shaft 32 can drive the lifting mechanism 20 to slide upward and then downward relative to the support seat 10.

[0034] By providing the rotating shaft 32 and the lifting mechanism 20, the mounting seat 31 can be rotated relative to the support seat 10 by the rotating shaft 32 to adjust the angle of the display device. The mounting seat 31 can slide in the vertical direction relative to the support seat 10 by the lifting mechanism 20 to provide sufficient space for the rotation movement of the display device. By providing an arc groove 101 on the support seat 10 and arranging a sliding block 33 on the mounting seat 31, when the mounting seat 31 rotates and switches positions relative to the support seat 10, the sliding block 33 can slide from one end of the arc groove 101 to the other end, and the arc groove 101 can limit the sliding block 33 from continuing to slide, so that the sense of confirmation after the mounting seat 31 is rotated into place is strong, and a buffer is arranged on the support seat 10. The impact structure 40 and the buffer structure 40 apply an elastic force upward in the vertical direction to the lifting mechanism 20. When the mounting seat 31 rotates and switches positions relative to the support seat 10, the elastic force of the buffer structure 40 can assist in the ascent during the process in which the rotating shaft 32 drives the lifting mechanism 20 to slide upward relative to the support seat 10, thereby improving the stability of the rotational ascent process. Moreover, when the rotating shaft 32 drives the lifting mechanism 20 to slide downward relative to the support seat 10, the elastic force of the buffer structure 40 can offset part of the gravity of the support seat 10 and the display device, and the support seat 10 can rely on the gravity of the display device to complete a smooth rotational descent action, thereby improving the stability of the rotational descent process.

[0035] In one embodiment of this implementation, please refer to Figures 4 to 6 , Figure 5 yes Figure 4 A schematic diagram of the structure of the support plate 122 and related components of the display device mounting bracket in the front view direction; Figure 6 yes Figure 5 The support base 10 is provided with a guide rail 121, and the lifting mechanism 20 includes a sliding plate 21, which is slidably matched with the guide rail 121, and the sliding plate 21 is connected to the buffer structure 40. In this way, the elastic force of the buffer structure 40 directly acts on the sliding plate 21 that is slidably matched with the guide rail 121, which helps to further improve the stability of the rotation and lifting.

[0036] In this embodiment, the guide rail 121 extends in the vertical direction, so that the sliding plate 21 can slide up and down in the vertical direction along the guide rail 121. The sliding plate 21 slides with the guide rail 121 through a ball (not shown), thereby reducing the friction generated during relative sliding.

[0037] In one embodiment of this implementation, please refer to Figures 4 to 6 , the number of guide rails 121 and buffer structure 40 are both two, the two guide rails 121 are arranged at intervals in the horizontal direction, the sliding plate 21 includes a first sliding portion 211, a connecting portion 212 and a second sliding portion 213 connected in sequence, the first sliding portion 211 and the second sliding portion 213 are respectively slidably matched with the two guide rails 121, and are respectively connected to the two buffer structures 40, and the connecting portion 212 is connected to the rotating shaft 32. It can be understood that the first sliding portion 211 and the second sliding portion 213 are respectively slidably matched with the two guide rails 121, so that the connecting portion 212 has better motion accuracy, and can fully absorb the torque load generated when the mounting seat 31 rotates relative to each other, which helps to improve the stability of the rotation and lifting.

[0038] In this embodiment, both the first sliding portion 211 and the second sliding portion 213 are provided with a connecting rail 2111 , and the connecting rail 2111 is installed with a ball bearing. The connecting rail 2111 is slidably matched with the guide rail 121 through the ball bearing.

[0039] In this embodiment, the connection part 212 is located between the first sliding part 211 and the second sliding part 213, and the rotation axis 32 is connected to the center of the connection part 212. It can be understood that the rotation direction of the display device when rotating up is opposite to the rotation direction when rotating down, and since the connection part 212 is located between the first sliding part 211 and the second sliding part 213 in this embodiment, the torque load generated by the display device can be well absorbed regardless of whether it is rotating up or rotating down, thereby improving the stability of the rotation and lifting.

[0040] In one embodiment of this implementation, please refer to Figures 4 to 6 The first sliding part 211 and / or the second sliding part 213 are provided with a lug 2101, which extends to the bottom side of the corresponding buffer structure 40, and one end of the buffer structure 40 is hung on the lug 2101. In this way, the installation structure of the buffer structure 40 and the lug 2101 is relatively simple, the installation difficulty is relatively low, and the buffer structure 40 can apply an elastic force in the vertical direction upward to the lug 2101.

[0041] In this embodiment, a lug 2101 is provided on a side of the first sliding portion 211 facing away from the second sliding portion 213 , and a lug 2101 is provided on a side of the second sliding portion 213 facing away from the first sliding portion 211 . The two lugs 2101 are connected to the two buffer structures 40 respectively.

[0042] In one embodiment of this implementation, please refer to Figures 4 to 6 The connecting portion 212 is provided with a connecting hole 2121, one end of the rotating shaft 32 is rotatably matched with the mounting seat 31, and the other end of the rotating shaft 32 is matched with the connecting hole 2121, and the connecting hole 2121 limits the rotation of the rotating shaft 32. In this way, the mounting seat 31 can rotate relative to the lifting mechanism 20.

[0043] Specifically, the end of the rotating shaft 32 away from the connecting portion 212 can be rotatably connected to the mounting seat 31 through a bearing or other device, or can be rotatably connected to the mounting seat 31 through a shaft hole matching method. In this embodiment, the cross-section of the end of the rotating shaft 32 away from the mounting seat 31 is roughly rectangular, and the cross-sectional shape of the connecting hole 2121 corresponds to it, so that after the rotating shaft 32 extends into the connecting hole 2121, the rotating shaft 32 and the connecting portion 212 are relatively fixed in the circumferential direction.

[0044] In one embodiment of this implementation, please refer to Figures 4 to 6 The support seat 10 is provided with a support plate 122, the guide rail 121 is mounted on the support plate 122, the lifting mechanism 20 includes a first clamping plate 22, a second clamping plate 23 and a locking member 24, the rotating shaft 32 passes through the sliding plate 21, the first clamping plate 22, the support plate 122 and the second clamping plate 23 in sequence, and is connected to the locking member 24, and the locking member 24 and the sliding plate 21 enable the first clamping plate 22 and the second clamping plate 23 to clamp the support plate 122. It can be understood that the first clamping plate 22 and the second clamping plate 23 clamp the support plate 122, and friction can be generated between the first clamping plate 22 and the support plate 122 and between the second clamping plate 23 and the support plate 122. Due to the existence of the above friction, when the user rotates the display device to rise, a certain damping feeling can be obtained, the speed of the rotation rise is reduced, and the stability of the rotation rise is improved. When the user rotates the display device to the highest point, the user lets go and allows the display device to drive the mounting seat 31 to rotate down, the above friction can reduce the speed of the rotation descent and improve the stability of the rotation descent. With such arrangement, the friction force generated by the first clamping plate 22 and the second clamping plate 23 clamping the support plate 122 can improve the stability of the rotation and lifting of the display device.

[0045] In this embodiment, in order to reduce costs and product weight, the housing 12 is made of cheap and light materials such as plastic, so the structural strength of the housing 12 is low. And in order to take into account the connection strength of the lifting mechanism 20 to bear the weight of the display device, the support plate 122 is made of a stronger material such as aluminum alloy, copper plate, steel, etc. The presence of the first clamping plate 22 and the second clamping plate 23 can transfer the gravity of the display device to the support plate 122 to better support the display device.

[0046] In this embodiment, in order to reduce the risk of excessive friction generated by the first clamping plate 22 and the second clamping plate 23 clamping the support plate 122, causing the lifting mechanism 20 to get stuck on the guide rail 121, the surface of the first clamping plate 22 facing the support plate 122 and the surface of the second clamping plate 23 facing the support plate 122 are provided with a plurality of strip protrusions 201 extending in the vertical direction. The strip protrusions 201 can provide a good damping feeling while taking into account the connection strength.

[0047] In one embodiment of this implementation, please refer to Figures 4 to 6 The lifting mechanism 20 includes a shaft ring 25, which is sleeved on the rotating shaft 32, and one end of the shaft ring 25 abuts against the mounting seat 31, and the other end of the shaft ring 25 abuts against the side of the sliding plate 21 facing away from the support plate 122. In this way, the shaft ring 25 can cooperate with the locking piece 24 to tighten the first clamping plate 22 and the second clamping plate 23 on the opposite sides of the support plate 122.

[0048] In this embodiment, the locking member 24 is threadedly connected to the rotating shaft 32, so that the friction between the first clamping plate 22 and the second clamping plate 23 and the support plate 122 can be adjusted by rotating the locking member 24. In addition, a rigid gasket 26 and an elastic gasket 27 are provided between the locking member 24 and the second clamping plate 23 to reduce the risk of the locking member 24 crushing the second clamping plate 23.

[0049] In one embodiment of this implementation, please refer to Figure 3 and Figure 7 , Figure 7 yes Figure 1 The structural diagram of the partial structure of the display device mounting bracket in the front view direction. The support base 10 is provided with a strip-shaped through hole 102, which is located on the top side of the arc-shaped slide groove 101, and the rotating shaft 32 is passed through the strip-shaped through hole 102. By providing the strip-shaped through hole 102 on the support base 10, the rotating shaft 32 is connected to the lifting mechanism 20 in the support base 10.

[0050] In one embodiment of this implementation, please refer to Figure 3 and Figure 7 The arc-shaped slide groove 101 includes a first end 1011 and a second end 1012 opposite to each other. In the vertical direction, the first end 1011 is farther from the rotation axis 32 than the second end 1012, and in the horizontal direction, the first end 1011 is farther from the rotation axis 32 than the second end 1012. This arrangement is convenient for switching between the horizontal and vertical display device states.

[0051] Specifically, when the mounting seat 31 is in the first position, the sliding block 33 is located at the first end 1011, and the sliding block 33 abuts against the inner wall at the first end 1011. When the mounting seat 31 is in the second position, the sliding block 33 is located at the second end 1012, and the sliding block 33 abuts against the inner wall at the second end 1012. The arc-shaped slide groove 101 is in an upwardly convex shape, and the first end 1011 and the second end 1012 are respectively the two lowest points of the arc-shaped slide groove 101, so that under the gravity of the display device, the sliding block 33 can be stuck in the first end 1011 or the second end 1012.

[0052] In one embodiment of this implementation, please refer to Figure 3 and Figure 7 The mounting seat 31 is constructed as a rectangular plate, the rotating shaft 32 is connected to the center of the mounting seat 31, and the sliding block 33 is connected to one of the corners of the mounting seat 31. In this way, the distance between the sliding block 33 and the rotating shaft 32 is longer, and the sliding block 33 has a larger sliding stroke, which helps to improve the stability of the rotation and lifting. In addition, after being rotated to the right position, that is, the display device is in a horizontal or vertical screen state, when the mounting seat 31 is in the first position or the second position, the sliding block 33 is located at one end of the arc-shaped slide groove 101, and the sliding block 33 is at a distance from the rotating shaft 32 in the horizontal direction, so as to utilize the gravity of the display device to maintain the relative position of the mounting seat 31 and the support seat 10 unchanged.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
