Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

The embodiment provides a support structure on which the display screen 20 can rotate and lift, and the rotation and lifting process is safer and more reliable without colliding with a desktop.

As shown in fig. 1 and 2, there is provided a display device including a base 10, a display screen 20, and a stand structure. The stand structure includes a stand body 30, a lifting assembly 40, and a rotating assembly 50.

In this embodiment, to achieve the lifting, the lifting assembly 40 includes a guide rail 41 fixed to the bracket body 30 and a connection plate 42 slidably connected to the guide rail 41. As an alternative embodiment, the guide rail 41 is a linear slide rail.

Further, to achieve the rotation, the rotation assembly 50 includes a connection member 51 connected to the connection plate 42 and a rotation plate 52 rotatably connected to the connection member 51.

Therefore, the display screen 20 can be fixedly connected with the rotating plate 52, so that the rotating plate 52 can rotate around the connecting member 51 and can be lifted on the lifting assembly 40 through the connecting member 51.

In this embodiment, the lifting assembly 40 further includes a constant force spring 70, and two ends of the constant force spring 70 are respectively connected to the bracket main body 30 and the connecting plate 42, so that the display screen 20 can be maintained at any height.

In order to prevent the display screen 20 from colliding with a desktop during the lifting and rotating processes, the stand structure further includes an unlocking key 80 and a lifting and rotating lock 90, the unlocking key 80 is fixedly disposed at the top of the stand body 30, and a first unlocking inclined plane 81 is disposed on the bottom surface of the unlocking key 80, as shown in fig. 2 and 3.

Furthermore, a lock hole 521 is formed in the rotating plate 52, a convex column 91 extending into the lock hole 521 is disposed on one side of the lifting rotating lock 90, and a second unlocking inclined plane 92 matched with the first unlocking inclined plane 81 is disposed on the top surface of the lifting rotating lock 90. An elastic member 93 connected to the elevating assembly 40 is connected to the other side of the elevating rotary lock 90. As an alternative embodiment, the elastic member 93 is a spring.

In this embodiment, when the display screen 20 is in the horizontal screen state and the height of the position is low (for example, lower than the set position or not reaching the highest position), the protruding column 91 of the lifting rotation lock 90 extends into the locking hole 521, so as to prohibit the rotation of the rotation plate 52 around the connecting member 51, thereby achieving the purpose of locking the rotation function and preventing the display screen 20 from rotating and colliding with the desktop. When the display screen 20 ascends through the lifting assembly 40, along with the contact and extrusion of the second unlocking inclined plane 92 and the first unlocking inclined plane 81, the convex column 91 of the lifting rotary lock 90 gradually exits from the lock hole 521 until completely exiting, so that the purpose of unlocking and rotating functions is achieved, and at the moment, the display screen 20 can be switched from a horizontal screen state to a vertical screen state. When the rotation function needs to be locked again, the display screen 20 can be rotated to the locking hole 521 to align with the protruding column 91, and then the display screen 20 is lowered, so that the second unlocking inclined plane 92 and the first unlocking inclined plane 81 are separated from each other, and the protruding column 91 is inserted into the locking hole 521 again under the action of the elastic piece 93, thereby achieving the purpose of locking the rotation function.

Example two

Furthermore, in order to solve the problem of collision with the desktop caused by the descending of the display screen 20 in the vertical screen state, in the embodiment, a locking lifting function is added, and the rotation function and the lifting function can be interlocked, that is, only one function operation can be performed at the same time, and the rotation function and the lifting function cannot be performed at the same time.

Specifically, the bracket body 30 is provided with a through slot 31, the connecting piece 51 passes through the through slot 31 to connect with the connecting plate 42, and the elastic piece 93 passes through the through slot 31 to connect with the connecting plate 42.

The through groove 31 includes a limiting groove 32 for limiting the lifting of the lifting rotary lock 90, and when the protruding pillar 91 gradually exits from the lock hole 521, the lifting rotary lock 90 gradually enters the limiting groove 32.

Therefore, when the display screen 20 unlocks the rotation function, the elevation rotation lock 90 is caught in the stopper groove 32. If the display screen 20 is rotated at this time, the lifting rotary lock 90 cannot lift due to the misalignment between the convex column 91 and the lock hole 521, so that the lifting function is locked at this time, and the purpose of prohibiting lifting in the vertical screen state is achieved, which is to lock the lifting function but unlock the rotation function.

When the display screen 20 needs to be lifted, the display screen 20 can be rotated to the horizontal screen state, so that the lock hole 521 is aligned with the convex column 91, and when the display screen 20 is lifted, the convex column 91 is inserted into the lock hole 521, and the lifting rotary lock 90 exits from the limit groove 32, which is a locking rotary function but an unlocking lifting function.

By combining the support structure described in the first and second embodiments, the lifting and rotating functions can be automatically locked and unlocked, so that the display screen 20 is prevented from colliding with a desktop, and the use safety is improved.

As an alternative to the first or second embodiment, the rotating assembly 50 further includes a fixing plate 53, a first friction plate 54 disposed between the fixing plate 53 and the rotating plate 52, and a second friction plate 55 disposed between the rotating plate 52 and the connecting member 51, as shown in fig. 4.

The rotating plate 52, the first friction plate 54 and the second friction plate 55 are sleeved on the connecting member 51, and the tightness is adjusted by the fixing plate 53, so that the rotating plate 52 can rotate around the connecting member 51.

EXAMPLE III

Generally, a cable connection is required between the base 10 and the display screen 20, and in order to avoid the cable passing through the bracket structure from being damaged by the lifting process of the display screen 20, the prior art generally adopts an external wiring avoiding movement structure. For this reason, on the basis of the first embodiment or the second embodiment, the support structure provided in the present embodiment further includes a wire harness assembly 60 to solve the technical problem, as shown in fig. 5 and 6.

Specifically, the harness assembly 60 includes a first link 61 and a second link 62. The first end of the first connecting rod 61 is hinged to the connecting plate 42, a first groove 611 for laying cables is formed in the first connecting rod 61, and a cable passing hole 613 is further formed through the first end of the first connecting rod 61.

The first end of the second link 62 is hinged to the second end of the first link 61, the second end of the second link 62 is hinged to the stand body 30, and the second link 62 is provided with a second groove 621 for laying cables.

As an alternative embodiment, the first link 61 and the second link 62 are hinged by an elastic coupling shaft 63.

Therefore, with the support structure provided in this embodiment, internal wiring is possible, and cables passing through the support structure can be laid in the first groove 611 and the second groove 621 and can be connected to the display screen 20 through the wire passing hole 613. In the lifting process of the display screen 20, along with the rotation of the first connecting rod 61 around the first end and the rotation of the second connecting rod 62 around the second end, the angle between the first connecting rod 61 and the second connecting rod 62 changes, but the length of the cable laying path is always kept unchanged, and the length is equal to the length of the first groove 611 and the second groove 621, so that the cable is prevented from being damaged in the lifting process of the display screen 20, the purpose of attractive routing is achieved, and the user experience is improved.

Furthermore, a first cable buckle 612 is arranged on a groove wall of the first groove 611, a second cable buckle 622 is arranged on a groove wall of the second groove 621, and the cable is laid at the first groove 611 and the second groove 621 and is buckled by the first cable buckle 612 and the second cable buckle 622, so that the cable can be prevented from being separated from the grooves, and further the cable is prevented from being damaged.

Example four

The embodiment provides a method for lifting and rotating a display screen, which can finish the rotation or lifting of the display screen 20 in one go only by single-hand or single-finger operation, and the operation is more convenient.

To rotate and raise the display screen 20 on the stand structure, the stand structure generally includes a raising and lowering assembly 40 and a rotating assembly 50, as shown in fig. 1-3.

Specifically, the lifting assembly 40 includes a guide rail 41 fixed to the bracket body 30 and a connection plate 42 slidably connected to the guide rail 41. The rotating assembly 50 includes a connecting member 51 connected to the connecting plate 42 and a rotating plate 52 rotatably connected to the connecting member 51 for mounting the display screen 20.

As shown in fig. 7, the display screen lifting and rotating method includes the following steps:

s101, when the connecting plate 42 is lower than the preset position height, locking the rotating plate 52 to prohibit the rotating plate from rotating on the connecting piece 51, and unlocking the connecting plate 42 to allow the connecting plate 42 to ascend and descend on the guide rail 41;

s102, when the connecting plate 42 reaches the preset position height, unlocking the rotating plate 52 to allow the rotating plate to rotate; wherein, when the rotation angle of the rotation plate 52 is 0 degree, the connection plate 42 is locked to prohibit its ascent but allow its descent; when the rotation angle of the rotation plate 52 is greater than 0 degrees, the connection plate 42 is locked to prohibit its ascent and descent.

It should be understood that the preset position height can be set appropriately according to the size of the display screen 20. In this embodiment, this position is also the highest position that the connecting plate 42 can reach.

Therefore, the display screen lifting and rotating method provided by the embodiment can push the display screen 20 to ascend or descend by a single hand or a single finger without rotation interference when the connecting plate 42 is lower than the preset position height. When the connecting plate 42 is lifted to the preset position height, since the lifting function is locked, and then a single hand or a single finger continues to apply upward force, the force application parts can be located at the bottoms of the two sides of the display screen 20, and the display screen 20 can rotate. When the display screen 20 is rotated, the ascending and descending functions are simultaneously locked, and the display screen 20 only has the rotating function without being interfered by the ascending and descending.

Further, when the connecting plate 42 is lower than the predetermined height, the display 20 is in a landscape state, as shown in fig. 8. So configured, the display screen 20 can be prevented from hitting the desktop as much as possible. Since the connecting plate 42 is lower than the predetermined height, it can be understood as being in a lower position, and the rotation is not possible at this time to avoid the collision of the table top due to the rotation in the lower position. When the connecting plate 42 reaches a preset position height, which can be understood as being at a higher position, it can rotate to switch from the horizontal screen to the vertical screen, as shown in fig. 9, and the rotation angle of the rotation plate 52 is 0 degree; however, when the vertical screen is in the vertical screen, the vertical screen cannot be lifted, so that the vertical screen is prevented from being lifted and collided with the tabletop, as shown in fig. 10, the rotation angle of the rotation plate 52 is 90 degrees.

Therefore, according to the display screen lifting and rotating method provided by the embodiment, not only can the display screen 20 be pushed to ascend or descend by a single hand or a single finger, but also the display screen 20 is not easy to collide with a desktop and be damaged.

It should be noted that the first, second, and third embodiments can be applied to implement the display screen lifting and rotating method provided by this embodiment. However, the display screen lifting and rotating method provided by this embodiment may also be implemented by other mechanical structures, and should also fall within the scope of this application.
