Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a display screen frame. Background Technology

[0002] Currently, some LED displays feature curved screens to meet the requirements of curved displays. At present, curved screens mainly rely on a curvature lock located on the side of the display frame facing away from the display module to achieve curvature adjustment. However, the addition of this curvature lock inevitably increases the overall thickness of the display, which is not conducive to the requirement for a thinner and lighter display. Furthermore, the curvature adjustment of this type of curved screen structure is relatively limited; both sides of the screen generally bend towards the same side of the display surface (front or back), failing to meet the diverse needs of curvature adjustment.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of a display screen frame provided in an embodiment of the present utility model. The display screen frame includes a first frame 10, a second frame 20, and a third frame 30.

[0034] Please combine Figure 2-7The second frame 20 is located between the first frame 10 and the third frame 30. The first frame 10 is rotatably connected to the side of the third frame 30 facing the third frame 30 and the side of the second frame 20 facing away from the third frame 30. The third frame 30 is rotatably connected to the side of the first frame 10 facing the second frame 20 facing away from the first frame 10. The first frame 10 and the third frame 30 can rotate in the same direction or in opposite directions relative to the second frame 20.

[0035] Specifically, the first frame 10, the second frame 20, and the third frame 30 are arranged side by side, with the second frame 20 in the center. The first frame 10 and the third frame 30 are located on the left and right sides of the second frame 20, respectively. The first frame 10 and the second frame 20 are rotatably connected, specifically, the side of the first frame 10 facing the third frame 30 is rotatably connected to the side of the second frame 20 facing away from the third frame 30. The specific connection method is not limited here, but will be described in detail in the following embodiments. The second frame 20 and the third frame 30 are rotatably connected, specifically, the side of the third frame 30 facing the first frame 10 is rotatably connected to the side of the second frame 20 facing away from the first frame 10. The specific connection method is not limited here, but will be described in detail in the following embodiments. However, the rotation directions of the first frame 10 and the third frame 30 relative to the second frame 20 can be either the same or opposite directions.

[0036] Specifically, when the display frame is not connected to other display frames, i.e., in single-screen mode, one scenario is that the first frame 10 and the third frame 30 can rotate in opposite directions relative to the second frame 20, such as... Figure 3a As shown, the first frame 10 on the left side rotates clockwise relative to the second frame 20 in the middle by an angle, while the first frame 10 on the right side rotates counterclockwise relative to the second frame 20 in the middle by an angle, thus causing the display screen to exhibit an inwardly curved shape, as shown. Figure 3b As shown, the first frame 10 on the left rotates counterclockwise relative to the second frame 20 in the middle by an angle, while the first frame 10 on the right rotates clockwise relative to the second frame 20 in the middle by an angle, thus causing the display screen to exhibit an outward curved shape; another possibility is that the first frame 10 and the third frame 30 can rotate in the same direction relative to the second frame 20, such as... Figure 3cAs shown, the first frame 10 on the left side rotates counterclockwise by an angle relative to the second frame 20 in the middle, and the first frame 10 on the right side also rotates counterclockwise by an angle relative to the second frame 20 in the middle, thus making the display screen appear to be curved in both the inner and outer arcs.

[0037] Furthermore, the display frame can be spliced ​​and connected with other display frames to form a multi-screen large-screen mode. Here, by controlling the first frame 10 and the third frame 30 of the multiple display frames to rotate in different directions relative to their second frame 20, the overall display screen presents a shape as shown in the image. Figure 4a The inner arc curvature shown makes the display screen appear as... Figure 4b The outward curvature shown, and the way it makes the display screen appear as... Figure 4c The inner and outer arc bending forms are shown.

[0038] In summary, in this embodiment of the present invention, through the rotational connection between the first frame 10 and the third frame 30 and the second frame 20 respectively, when the first frame 10 and the third frame 30 rotate in the same direction relative to the second frame 20, the screen presents an inner and outer curved shape; when the first frame 10 and the third frame 30 rotate in opposite directions relative to the second frame 20, the screen presents an inner or outer curved shape, thereby enriching the curvature adjustment form of the display screen and effectively increasing the diversity of the curvature adjustment of the display screen.

[0039] Furthermore, in other preferred embodiments of this utility model, the first frame 10 and the third frame 30 are both U-shaped structures 40 with openings facing the second frame 20. Both ends of the U-shaped structure 40 are provided with arc-shaped protrusions 410, and the two sides of the second frame 20 are provided with arc-shaped grooves 210 that can accommodate the arc-shaped protrusions 410. The arc-shaped protrusions 410 can slide in the arc-shaped grooves 210.

[0040] Specifically, the first frame 10 and the third frame 30 are U-shaped structures 40 with opposite openings, and the two opposite sides of the second frame 20 are respectively opposite the openings of the two U-shaped structures 40. Four arc-shaped protrusions 410 are respectively provided at the openings of the two U-shaped structures 40, and four arc-shaped grooves 210 are provided at the ends of the opposite sides of the second frame 20. The arc-shaped protrusions 410 can slide back and forth in the arc-shaped grooves 210, thereby enabling the first frame 10 and the third frame 30 to be rotatably connected relative to the opposite sides of the second frame 20.

[0041] Furthermore, in other preferred embodiments of this utility model, the arc-shaped groove 210 is provided with a bead 2101 on its groove wall, and the arc-shaped protrusion 410 is provided with a plurality of grooves 4101 along its arc length direction that can accommodate the bead 2101.

[0042] Specifically, the second frame 20 has a detachably connected cover plate 2103 on its mutually distant sides. The cover plate 2103 can be regarded as the groove wall of the arc-shaped slide groove 210. The ball bearing 2101 is disposed on the side of the cover plate 2103 facing the arc-shaped protrusion 410. The arc-shaped protrusion 410 is provided with a plurality of grooves 4101. The plurality of grooves 4101 are arranged along the arc length direction of the arc-shaped protrusion 410. The ball bearing 2101 can be accommodated in the grooves 4101. When the arc-shaped protrusion 410 slides in the arc-shaped slide groove 210, the ball bearing 2101 can switch to different grooves 4101 and make a "click" sound, providing timely and effective feedback on the adjustment of the display frame angle from both tactile and auditory perspectives.

[0043] In addition, in other preferred embodiments of the present invention, the arc-shaped protrusion 410 is provided with a guide hole 4102 along its arc length direction, and the arc-shaped groove 210 is provided with a limiting post 2102 that can slide in the guide hole 4102.

[0044] Specifically, the guide hole 4102 is set along the arc length direction of the arc protrusion 410 and is an arc-shaped elongated hole. The guide hole 4102 is set on the groove wall of the arc-shaped slide 210. Specifically, the guide hole 4102 is set on the side of the arc-shaped slide 210 opposite to the cover plate 2103, so that the first frame 10 (the third frame 30) and the second frame 20 can be easily installed and connected. This design can provide guidance for the rotation of the first frame 10 (the third frame 30) relative to the second frame 20, making its rotation smoother.

[0045] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes a locking assembly 50 for locking the sliding of the arc-shaped protrusion 410 in the arc-shaped groove 210, including a first locking rod 510, a second locking rod 520, and a locking sleeve 530 connected to a first handle 501. The first locking rod 510 and the second locking rod 520 are located at both ends of the locking sleeve 530 and are threadedly connected thereto. The ends of the first locking rod 510 and the second locking rod 520 that are far apart from each other are rotatably connected to the arc-shaped protrusion 410 on both sides.

[0046] The first locking rod 510 has a rubber pad 5101 at one end away from the locking sleeve 530. The groove wall of the arc-shaped sliding groove 210 has a through hole 2104 for the first locking rod 510 to pass through. The through hole 2104 has a recess 2105 that can accommodate the rubber pad 5101.

[0047] Specifically, the first locking rod 510 and the second locking rod 520 are sleeved on the two ends of the locking sleeve 530 to form the locking assembly 50. Both are threadedly connected to the locking sleeve 530. Rotating the locking sleeve 530 allows the ends of the first locking rod 510 and the second locking rod 520 to move to both sides. Here, the locking sleeve 530 is disposed within a sleeve 220 on the side of the second frame 20. The first handle 501 passes through the sleeve 220 and is fixedly connected to the locking sleeve 530. Rotating the first handle 501 allows the locking sleeve 530 to rotate within the sleeve 220. The rubber pad 5101 is disposed at the end of the first locking rod 510 away from the locking sleeve 530. The through hole 2104 is disposed on the groove wall of the arc-shaped groove 210 near the side of the first locking rod 510. The through hole 2104 allows the end of the first locking rod 510 to pass through and rotatably connect with the arc-shaped protrusion 410. The through hole 2104 is provided with a capacity to accommodate... The recessed platform 2105 of the rubber pad 5101 allows the rubber pad 5101 to abut against the recessed platform 2105. For example, when the first handle 501 is rotated, causing the locking sleeve 530 to rotate, and thus pushing the first locking rod 510 and the second locking rod 520 to move to both sides, when the rubber pad 5101 abuts against the recessed platform 2105, the arc-shaped protrusion 410 connected to the first locking rod 510 and the second locking rod 520 can no longer slide relative to the arc-shaped groove 210, that is, against the first frame... The frame 10 and the third frame 30 are locked relative to the rotation of the second frame 20; if unlocking is required, the first handle 501 is rotated in the opposite direction to drive the lock sleeve 530 to rotate, thereby driving the first locking rod 510 and the second locking rod 520 to move towards the center. At this time, the rubber pad 5101 will separate from the recess 2105, and the arc-shaped protrusion 410 connected to the first locking rod 510 and the second locking rod 520 can slide relative to the arc-shaped groove 210.

[0048] Furthermore, in other preferred embodiments of the present invention, the locking assembly 50 further includes a spring 540 sleeved on the end of the first locking rod 510 away from the locking sleeve 530, one end of the spring 540 abutting against the arc-shaped protrusion 410, and the other end of the spring 540 abutting against the rubber pad 5101.

[0049] Specifically, the spring 540 is sleeved on the first locking rod 510 above the rubber pad 5101, with its two ends abutting against the arc-shaped protrusion 410 and the rubber pad 5101, respectively. With this design, when the first handle 501 is rotated in the opposite direction, the locking sleeve 530 rotates, and the first locking rod 510 and the second locking rod 520 move towards the center, thereby removing the pressure on the rubber pad 5101. At this time, under the action of the elastic force of the spring 540, the rubber pad 5101 will quickly separate from the recess 2105, and the arc-shaped protrusion 410 connected to the first locking rod 510 and the second locking rod 520 can quickly slide relative to the arc-shaped groove 210 to improve the unlocking efficiency of the locking assembly 50.

[0050] In other preferred embodiments of the present invention, the display screen frame further includes a first reinforcing plate 101, a second reinforcing plate 201, and a third reinforcing plate 301, wherein the first reinforcing plate 101, the second reinforcing plate 201, and the third reinforcing plate 301 are respectively disposed on the same side of the first frame 10, the second frame 20, and the third frame 30.

[0051] Specifically, the first reinforcing plate 101, the second reinforcing plate 201, and the third reinforcing plate 301 correspond to the first frame 10, the second frame 20, and the third frame 30, respectively, and are detachably connected to the same side of the first frame 10, the second frame 20, and the third frame 30, respectively. The first reinforcing plate 101, the second reinforcing plate 201, and the third reinforcing plate 301 include, but are not limited to, carbon fiber plates, which can not only meet the lightweight requirements of the display frame, but also effectively improve the overall strength of the display frame.

[0052] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes a first elastic steel sheet 103 and a second elastic steel sheet 104. The first elastic steel sheet 103 is disposed on the side of the first reinforcing plate 101 and the second reinforcing plate 201 facing away from the first frame 10 and the second frame 20, and the second elastic steel sheet 104 is disposed on the side of the second reinforcing plate 201 and the third reinforcing plate 301 facing away from the second frame 20 and the third frame 30.

[0053] Specifically, the first elastic steel sheet 103 covers the entire first reinforcing plate 101 and part of the second reinforcing plate 201, and the second elastic steel sheet 104 covers the entire third reinforcing plate 301 and part of the second reinforcing plate 201. That is, the splicing seam of the first elastic steel sheet 103 and the second elastic steel sheet 104 is located above the side of the second reinforcing plate 201 facing away from the second frame 20. Here, the arrangement of the first elastic steel sheet 103 and the second elastic steel sheet 104 can provide sufficient elasticity for the display frame when it bends, making its curvature more linear, thereby improving the curved display effect of the curved display screen.

[0054] In addition, in other preferred embodiments of the present invention, a power supply box 60 is provided inside the second frame 20, and an electrical connector 610 is provided at the end of the power supply box 60.

[0055] The power supply box 60 is equipped with an eccentric wheel (not shown in the figure) that can drive the electrical connector 610 to extend out of the second frame 20 or retract into the second frame 20.

[0056] Here, the second frame 20 is a hollow frame structure, and the power supply box 60 is disposed within the second frame 20. An electrical connector 610 is provided at the end of the power supply box 60. The electrical connector 610 is used for electrical connection to other display screen frames or to external circuits. An eccentric wheel is disposed inside the power supply box 60 and connected to the electrical connector 610. A third handle 620 is provided on the outer shell of the power supply box 60. The third handle 620 can drive the eccentric wheel to rotate, thereby causing the electrical connector 610 to extend outside or retract inside the second frame 20, facilitating the expansion and storage of the display screen frame. The third handle 620 can fold towards the surface of the power supply box 60 shell to minimize the overall thickness of the display screen frame. Alternatively, the third handle 620 can protrude from the surface of the power supply box 60 shell for easy rotation.

[0057] Furthermore, in other preferred embodiments of the present invention, a lifting pin 70 with a pin hole 710 is provided on one side of the first frame 10 and the third frame 30.

[0058] The first frame 10 and the third frame 30 are provided with connecting holes 80 on opposite sides, into which the hanging pin 70 can be inserted. The frame body on the same side of the first frame 10 and the third frame 30 is provided with a pin 90 that can move in and out of the connecting hole 80 under the action of the second handle 502, and the pin 90 can be inserted into the pin hole 710.

[0059] Specifically, the lifting pin 70 and the connecting hole 80 are respectively located at the top and bottom of the display screen frame. The lifting pin 70 protrudes from the frame of the display screen frame, and a pin hole 710 is provided on the lifting pin 70 for hoisting purposes. The connecting hole 80 is positioned opposite to the lifting pin 70, and the lifting pin 70 can be inserted into the connecting hole 80 to allow the two display screen frames to be joined vertically. A pin 90 is also provided on the side of the first frame 10 and the third frame 30 where the connecting hole 80 is located. The frame is also equipped with a second handle 502, which can drive the pin 90 to slide back and forth within the frame, so that the end of the pin 90 is inserted into the pin hole 710. At this time, the hanging pin 70 cannot be dislodged from the connecting hole 80, thereby locking the splicing connection of the upper and lower display frames. If unlocking is required, the second handle 502 is used to drive the pin 90 to slide in the opposite direction within the frame, so that the end of the pin 90 is dislodged from the pin hole 710. At this time, the hanging pin 70 can be dislodged from the connecting hole 80, thereby unlocking the splicing connection of the upper and lower display frames.

[0060] Furthermore, in other preferred embodiments of the present invention, locking slots and unlocking slots capable of accommodating the second handle 502 are provided on the frame surfaces of the first frame 10 and the third frame 30, corresponding to the positions of the second handle 502 in the locked and unlocked states.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
