DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] like Figure 1-3 As shown, the utility model provides a display screen rotation device, including a bracket 1 and a rotating block 2, wherein the bracket 1 is rotatably connected to the rotating block 2, the bracket 1 is provided with a fixing surface 11, and the fixing surface 11 is provided with a fixing seat 12 extending outward, and the rotating block 2 is provided with a through hole 21 corresponding to the fixing seat 12, and the rotating block 2 is rotatably sleeved on the fixing seat 12 through the through hole 21;

[0033] A first damping mechanism 3 is provided on the end surface of the rotating block 2 away from the fixed surface 11. The first damping mechanism 3 is used to fix the rotating block 2 on the bracket 1 and has a damping effect on the rotation of the rotating block 2, so that the rotating block 2 has a fixed angle after rotation.

[0034] During use, the rotating block 2 is installed on the back of the display screen 4 and fixedly connected to the display screen 4. When the consumer manually rotates the display screen 4 to a certain angle, the rotating block 2 can be synchronously driven to rotate relative to the bracket 1. Under the damping action of the first damping mechanism 3, the rotating block 2 and the display screen 4 are maintained and fixed at the rotation angle.

[0035] Specifically, such as Figure 4-5As shown, the first damping mechanism 3 includes a fixed plate 31 and a first damping member 32. The fixed plate 31 and the first damping member 32 are coaxially arranged. The fixed plate 31 is located on the end surface of the rotating block 2 away from the fixed surface 11, and the fixed plate 31 is fixedly connected to the fixing seat 12. The diameter of the fixed plate 31 is larger than the diameter of the through hole 21, thereby preventing the rotating block 2 from falling off the fixing seat 12; the first damping member 32 is arranged between the rotating block 2 and the fixed plate 31, the first damping member 32 is sleeved on the fixing seat 12 and fixedly connected to the rotating block 2, and the first damping member 32 and the fixed plate 31 are pressed against each other and rotated in abutment with each other;

[0036] When in use, the rotating block 2 rotates and drives the first damping member 32 to rotate synchronously. Since the other end surface of the first damping member 32 is pressed and abutted against the fixed plate 31, the first damping member 32 forms a rotational friction force on the fixed plate 31 when rotating, thereby generating a deceleration damping effect.

[0037] Furthermore, the rotating block 2 is provided with a plurality of first mounting holes 22, which are arranged in a ring array around the through hole 21. The first damping member 32 is provided with a first clamping block 321 adapted to the first mounting hole 22. The first clamping block 321 is engaged with the first mounting hole 22 to achieve a fixed connection between the rotating block 2 and the first damping member 32, so that the rotation of the rotating block 2 synchronously drives the rotation of the first damping member 32.

[0038] Preferably, there are four first mounting holes 22;

[0039] Furthermore, the fixing plate 31 and the fixing seat 12 passing through the rotating block 2 are detachably fixedly connected. The fixing seat 12 and the fixing plate 31 are fixedly connected by screws 5. By installing or removing the screws 5, the rotating block 2 and the bracket 1 are fixed or separated, making it convenient to assemble and disassemble the rotating block 2 and the bracket 1, thereby improving assembly efficiency and facilitating production.

[0040] Furthermore, a limiting hole 311 is provided on the fixing plate 31, and a limiting post 121 corresponding to the limiting hole 311 is provided on the fixing seat 12, and the limiting post 121 passes through the limiting hole 311. The limiting hole 311 and the limiting post 121 are provided to fix the fixing plate 31, thereby preventing excessive friction between the first damping member 32 and the fixing plate 31, which would cause the fixing plate 31 to rotate and affect the user experience.

[0041] Preferably, there are two limiting holes 311 , and the limiting holes 311 are symmetrically arranged around the center of the fixing plate 31 .

[0042] Specifically, such as Figure 6-9 As shown, the outer edge of the fixed plate 31 is provided with an inwardly recessed limiting groove 312, and the rotating block 2 is fixedly provided with a limiting protrusion 23 corresponding to the limiting groove 312, and the limiting protrusion 23 slides in the limiting groove 312, wherein the two ends of the limiting groove 312 are respectively provided with an end wall 1 3121 and an end wall 2 3122; when the rotating block 2 rotates, it drives the limiting protrusion 23 to rotate, and when the limiting protrusion 23 abuts against the end wall 1 3121, the rotating block 2 is located at the first rotation position P2; when the limiting protrusion 23 abuts against the end wall 2 3122, the rotating block 2 is located at the second rotation position P3;

[0043] Furthermore, when the display screen 4 is in the corrected initial position P1, the limiting protrusion 23 is exactly located in the middle of the limiting groove 312; when the limiting protrusion 23 abuts against the end wall 1 3121, and the rotating block 2 is in the first rotation position P2, the display screen 4 rotates 90° to the right in the corrected state; when the limiting protrusion 23 abuts against the end wall 2 3122, and the rotating block 2 is in the second rotation position P3, the display screen 4 rotates 90° to the left in the corrected state; that is, when the display screen 4 rotates from the first rotation position P2 to the second rotation position P3, the rotation angle is 180°, that is, the maximum rotation angle of the display screen 4 is 180°.

[0044] Specifically, such as Figure 5 As shown, the end surface of the rotating block 2 close to the fixed plate 31 is further provided with an inwardly recessed mounting cavity 24 in an annular structure. The diameter of the mounting cavity 24 is adapted to the diameter of the first damping mechanism 3, and the first damping mechanism 3 is disposed in the mounting cavity 24. The first mounting hole 22 is also disposed in the mounting cavity 24.

[0045] Furthermore, the depth of the mounting cavity 24 is greater than or equal to the thickness of the first damping mechanism 3, so that the first damping mechanism 3 is accommodated in the mounting cavity 24, so as to reduce the protruding volume of the first damping mechanism 3 on the rotating block 2, thereby improving the overall beauty and simplicity of the device while improving the space utilization of the device.

[0046] Specifically, such as Figure 10As shown, a second damping mechanism 6 is further provided between the fixed surface 11 and the rotating block 2. The second damping mechanism 6 is sleeved on the fixed seat 12 and includes a fixing member 61 and a second damping member 62. The fixing member 61 and the second damping member 62 are coaxially arranged, and the fixing member 61 is fixedly connected to the fixed surface 11; the second damping member 62 is provided between the rotating block 2 and the fixing member 61, and the second damping member 62 is fixedly connected to the rotating block 2. The fixing member 61 and the second damping member 62 are pressed against each other and rotated in abutment with each other;

[0047] When in use, the rotation of the rotating block 2 also drives the second damping member 62 to rotate synchronously. Since the second damping member 62 is pressed and abutted against the fixing member 61, the second damping member 62 also generates a rotational friction force on the fixing member 61 when rotating, thereby generating a deceleration damping effect.

[0048] Furthermore, the rotating block 2 is provided with a plurality of second mounting holes 25, which are arranged in a ring array around the through hole 21. The second damping member 62 is provided with a second clamping block 621 adapted to the second mounting hole 25. The second clamping block 621 is clamped in the second mounting hole 25 to achieve a fixed connection between the rotating block 2 and the second damping member 62, so that the rotation of the rotating block 2 synchronously drives the rotation of the second damping member 62.

[0049] Furthermore, the first mounting hole 22 and the second mounting hole 25 are spaced apart so that the first damping member 32 and the second damping member 62 are respectively fixed to the two opposite end surfaces of the rotating block 2 without interfering with each other;

[0050] Preferably, there are four second mounting holes 25 .

[0051] Specifically, a guide groove 122 recessed inward is provided on the peripheral wall of the fixing seat 12, and a guide block 611 corresponding to the guide groove 122 is provided on the inner wall of the fixing member 61. The guide block 611 is slidably disposed in the guide groove 122.

[0052] Furthermore, there are four guide grooves 122 in total, and the four guide grooves 122 are arranged in a circular array around the center of the fixing seat 12;

[0053] The guide groove 122 and the guide block 611 provide a guide for the installation of the fixing member 61 and the fixing seat 12, and can also effectively fix the fixing member 61 on the fixing surface 11, thereby preventing the fixing member 61 from rotating due to excessive friction with the second damping member 62, thereby affecting the damping effect.

[0054] Preferably, a receiving groove 111 corresponding to the fixing member 61 is provided on the fixing surface 11 , and the fixing member 61 is arranged in the receiving groove 111 , thereby making the rotating device more concise and beautiful.

[0055] Specifically, such as Figure 3 As shown in FIG11 , a rear cover 7 is provided at one end of the rotating block 2 close to the second damping mechanism 6 . The rear cover 7 is sleeved on the bracket 1 and fixedly connected to the rotating block 2 . A connecting hole 71 is provided on the rear cover 7 . The diameter of the connecting hole 71 corresponds to the diameter of the fixing surface 11 . When installed, the fixing surface 11 is arranged in the connecting hole 71 .

[0056] Furthermore, a receiving cavity 72 is provided on a side of the rear cover 7 close to the rotating block 2, and the rotating block 2 is disposed in the receiving cavity 72;

[0057] By setting the rear cover 7, the fixed surface 11, the rotating block 2, the first damping mechanism 3 and the second damping mechanism 6 are all set in the rear cover 7, making the rotating device more integrated as a whole, thereby effectively improving the overall aesthetics of the rotating device and making it more concise.

[0058] The innovation of the present invention lies in that damping mechanisms are provided at both ends of the rotating block, so that the rotating block is subjected to uniform force under the action of damping, thereby improving the rotational stability and service life; at the same time, the back cover, the accommodating cavity, the storage groove and the installation cavity are provided to hide multiple internal parts in the device, thereby improving the overall aesthetics of the device and making it more concise.
