A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] See also Figures 1-12 The embodiment of the utility model provides a dynamic left-right swing mechanism for a screen, comprising a base 3, a receiving bracket 1, a guide assembly, and a crank swing assembly. The base 3 is provided with an overall V-shaped guide rail 31 arranged in a transverse direction and the V-shaped opening is arranged forward. The guide assembly includes a guide rod 2 slidably connected to the base 3 in the front-back direction. The crank swing assembly includes a rotation drive assembly 5 installed on the base 3 and a crank 4 connected to the output end of the rotation drive assembly 5. The crank 4 is provided with a linear slide rail 41. The front side of the receiving bracket 1 is provided with a screen The installed assembly part 10, the front part of the receiving bracket 1 is rotatably connected to the front end of the guide rod 2 through the adapter assembly 7 with the vertical axis, the rear part of the receiving bracket 1 is provided with a receiving assembly 6 which can be rotatably slidably fitted to the V-shaped guide rail 31, and the receiving assembly 6 can be rotatably slidably fitted to the linear slide rail 41, and the rotation drive assembly 5 is used to drive the crank 4 to swing left or right, so that the crank 4 drives the receiving assembly 6 to move along the V-shaped guide rail 31 to the left front or right front, thereby making the front part of the receiving bracket 1 rotate left and right around the adapter assembly 7.

[0037] The above scheme guides the moving track of the receiving assembly 6 by arranging a V-shaped guide rail 31 on the base 3, so that when the rotating driving assembly 5 drives the crank 4 to swing left or right, the crank 4 drives the receiving assembly 6 to move to the left front or right front along the V-shaped guide rail 31, and because the receiving assembly 6 is rotatably slidably matched to the linear slide rail 41 of the crank 4, the receiving assembly 6 will not be stuck in the V-shaped guide rail 31 due to interference when the crank 4 swings left or right; at the same time, the receiving assembly 6 is received at the rear of the receiving bracket 1. During the process of pushing component 6 to the left front or right front, in the front-to-back direction, due to the action of the adapter component 7, the guide rod 2 will move forward synchronously with the front part of the receiving bracket 1, thereby realizing the front-to-back telescopic function of the assembly part 10 on the front side of the receiving bracket 1; in the left-to-right direction, due to the action of the receiving component 6, the rear part of the receiving bracket 1 will be displaced in the left-to-right direction, so the front part of the receiving bracket 1 will rotate left-to-right around the adapter component 7, thereby realizing the left-to-right swinging function of the assembly part 10 on the front side of the receiving bracket 1, and the overall operation is stable and reliable.

[0038] To make the description more specific, Figure 1 and Figure 10As shown, the base 3 includes a sliding surface 30 in the transverse direction. The V-shaped guide rail 31 is a V-shaped guide groove vertically penetrating the sliding surface 30, and the linear slide rail 41 is a linear chute. The receiving bracket 1 is located above the sliding surface 30, and the crank 4 is located below the sliding surface 30. The receiving assembly 6 includes a receiving pin 61. The upper end of the receiving pin 61 is connected to the rear of the receiving bracket 1, and the lower end of the receiving pin 61 passes through the V-shaped guide groove and is slidably inserted into the linear chute, so that the overall structure is compact and the layout is reasonable. It should be understood that the positions of the receiving bracket 1 and the crank 4 relative to the sliding surface 30 can be adjusted as needed and should not be regarded as actual limitations. Further, a V-shaped lining 311 is attached to the groove wall of the V-shaped guide groove. The V-shaped lining 311 has good wear resistance and can effectively reduce the wear of the V-shaped guide groove.

[0039] Combined with Figure 3 and Figure 4 As shown, as an improved solution to this embodiment, the lower side surface of the receiving bracket 1 slidably abuts against the upper side of the sliding surface 30. The sliding surface 30 is provided with an oil storage groove 33 for storing lubricating oil to ensure the more stable movement of the receiving bracket 1.

[0040] It should be noted that the so-called "the overall is in the shape of the V-shaped guide rail 31" in this embodiment means that the overall shape of the V-shaped guide rail 31 in the transverse direction is V-shaped, and the V-shaped here includes conventional variants that are roughly similar to the V-shaped in shape, such as U-shaped, etc.; in addition, the V-shaped guide rail 31 can be a left-right symmetric V-shaped, in which case the swing angles of the receiving bracket 1 to the left or right are equal; or the V-shaped guide rail 31 can also be a left-right asymmetric V-shaped, in which case the swing angles of the receiving bracket 1 to the left or right are not equal, and specifically can be adjusted according to actual needs, and this design does not make any limitations.

[0041] It should be noted that the so-called "the guide rod 2 slidably connected to the base 3 in the front-rear direction" in this embodiment means roughly in the front-rear direction, that is, a certain degree of deviation in the sliding direction of the guide rod 2 is allowed. When the sliding direction of the guide rod 2 is strictly in the front-rear direction, the swing angles of the receiving bracket 1 to the left or right are equal; when the sliding direction of the guide rod 2 is a front-rear direction with deviation, the swing angles of the receiving bracket 1 to the left or right are not equal; in addition, when the position of the guide rod 2 relative to the base 3 is directly opposite to the middle in the left-right direction of the V-shaped guide rail 31, the swing angles of the receiving bracket 1 to the left or right are equal; when the position of the guide rod 2 relative to the base 3 is offset from the middle in the left-right direction of the V-shaped guide rail 31, the swing angles of the receiving bracket 1 to the left or right are not equal, that is, the specific sliding direction of the guide rod 2 and the position of the guide rod 2 relative to the base 3 can be adjusted as needed, and this design does not make any limitations. In this embodiment, the guide rod 2 is slidably connected to the upper side of the sliding surface 30 of the base 3 in the front-rear direction, and the position of the guide rod 2 relative to the sliding surface 30 is roughly located in the middle in the left-right direction of the V-shaped guide rail 31.

[0042] To realize the stable forward and backward sliding of the guide rod 2 relative to the base 3, the guiding assembly further includes a guide base 32. The guide base 32 is connected to the upper side of the sliding surface 30 of the base 3. The guide base 32 is provided with a guide hole 321 opened in the front-back direction. The hole wall of the guide hole 321 is provided with a third wear-resistant bushing 322. The middle part of the guide rod 2 is slidably inserted into the guide hole 321, so as to realize the stable forward and backward sliding of the guide rod 2.

[0043] Combined with Figure 5 and Figure 11 As shown, in this embodiment, the rear part of the receiving bracket 1 is provided with a first through hole 11 in the vertical direction. The linear sliding groove penetrates through the crank 4 in the vertical direction. The receiving assembly 6 further includes a first spring 62 and a first nut 63. The upper end of the receiving pin 61 is provided with a brim located above the receiving bracket 1. The first spring 62 is sleeved on the receiving pin 61 and the first spring 62 is located between the brim of the receiving pin 61 and the upper side surface of the receiving bracket 1. The lower end of the receiving pin 61 sequentially passes through the first through hole 11, the V-shaped guide groove and the linear sliding groove downward. The first nut 63 is screwed to the lower end of the receiving pin 61 to achieve locking. The existence of the first spring 62 can compensate for the assembly error and dimensional error, and can avoid the problem that the first nut 63 is too tight when connected to the lower end of the receiving pin 61, resulting in the receiving pin 61 being stuck relative to the linear sliding groove and the V-shaped guide groove.

[0044] Furthermore, the hole wall of the first through hole 11 is provided with a first wear-resistant bushing 12. The first wear-resistant bushing 12 has a flange extending to the upper side surface of the receiving bracket 1. The upper end of the first spring 62 abuts against the brim of the receiving pin 61 and the lower end abuts against the flange of the first wear-resistant bushing 12. A linear lining 42 is attached to the groove wall of the linear sliding groove. The linear lining 42 has a flange extending to the lower side surface of the crank 4. The receiving assembly 6 further includes a wear-resistant gasket 64 located between the flange of the linear lining 42 and the first nut 63. The wear-resistant gasket 64 abuts against the flange of the linear lining 42 under the locking action of the first nut 63, so as to effectively improve the durability and avoid problems such as looseness and noise caused by the wear of the first through hole 11 and the linear sliding groove.

[0045] In this embodiment, a vertical threaded hole 13 is provided at the front portion of the receiving bracket 1, and a vertical adapter hole 21 is provided at the front end of the guide rod 2. The adapter assembly 7 includes an adapter pin 71, a second spring 72 and a second nut 73. The lower end of the adapter pin 71 is provided with a brim located below the guide rod 2. The second spring 72 is sleeved on the adapter pin 71 and the second spring 72 is located between the brim of the adapter pin 71 and the lower side surface of the guide rod 2. The upper end of the adapter pin 71 passes upward through the adapter hole 21 and is screwed to the threaded hole 13. The second nut 73 is screwed to the upper end of the adapter pin 71 to achieve locking. The above structure realizes the rotational connection between the front portion of the receiving bracket 1 and the front end of the guide rod 2 through the adapter pin 71. At the same time, the existence of the second spring 72 can compensate for assembly errors and dimensional errors, and can avoid the problem of the guide rod 2 being stuck due to excessive tightening of the second nut 73 when connected to the upper end of the adapter pin 71.

[0046] Furthermore, a second wear-resistant bushing 22 is provided on the hole wall of the adapter hole 21, and the second wear-resistant bushing 22 is provided with an upper flange extending to the upper side of the guide rod 2 and a lower flange extending to the lower side of the guide rod 2. The upper end of the second spring 72 abuts against the lower flange of the second wear-resistant bushing 22 and the lower end abuts against the brim of the adapter pin 71, thereby effectively improving durability and avoiding problems such as loosening and noise caused by wear of the threaded hole 13.

[0047] Combination Figure 1 and Figure 11 As shown, in this embodiment, the rotation drive assembly 5 includes a motor 52, a reducer 53 and a transmission shaft 51. The transmission shaft 51 is rotatably connected to the base 3 with the vertical axis as the axis. The reducer 53 preferably includes a worm wheel 531 and a worm 532. The worm wheel 531 is fixedly sleeved on the middle part of the transmission shaft 51. The worm 532 is connected to the output shaft of the motor 52. The worm wheel 531 and the worm 532 are meshed with each other, so that when the motor 52 drives the worm 532 to rotate, the worm wheel 531 drives the transmission shaft 51 to rotate. One end of the crank 4 is connected to the upper part of the transmission shaft 51, so that when the transmission shaft 51 rotates, the crank 4 is driven by the transmission shaft 51 to swing left or right.

[0048] Combination Figure 1 and Figure 12 As shown, further, a damper 8 is provided between the transmission shaft 51 and the base 3, thereby effectively reducing the shaking of the receiving bracket 1. The damper 8 can be a form in the prior art. In this embodiment, the damper 8 includes an annular outer seat 81, a friction ring 83 and an inner shaft 82.
