Technical Field

[0001] This application relates to the field of display device technology, and in particular to an angle adjustment component and a display device. Background Technology

[0002] Existing curved video wall displays are composed of multiple display units spliced ​​together. When adjacent display units are joined, they form a certain angle, resulting in a roughly curved surface. Currently, a curved adjuster is installed between adjacent display units to adjust their angle. This adjuster has a curved slide rail, and the two display units are placed on the rail and slide to adjust the angle. However, precisely because the curved guide rail allows for stepless adjustment of the angle between the two display units, the angle cannot be precisely adjusted to a specific angle to meet the on-site display layout requirements. Summary of the Invention

The angle pad has a first connecting surface and a second connecting surface that are arranged opposite to each other and have a preset included angle. The first connecting surface and the second connecting surface are respectively connected to two adjacent display devices. The pulling mechanism is connected to another of the display devices, and one end of the pulling mechanism is detachably connected to the locking component; The transmission device drives the locking component to slide relative to the first mounting base under the pushing action of the angle pad.

[0011] Preferably, the pulling mechanism further includes a pulling device located between the second mounting base and the locking rod.

[0012] Preferably, the angle pad has a mounting hole, and the end of the traction mechanism passes through the mounting hole.

[0013] To address the same technical problem, this application also provides a display device including the angle adjustment component described above.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: The angle adjustment assembly includes a telescopic mechanism, an angle pad, and a pulling mechanism. The telescopic mechanism and the pulling mechanism are respectively located on two adjacent display devices. The transmission device of the telescopic mechanism can drive the locking component to slide relative to the first mounting base under the pushing action of the angle pad.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0018] 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 application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Example 1 Combination Figures 1 to 16As shown, the angle adjustment component 1 of this application is schematically displayed. The angle adjustment component 1 is used to adjust the angle between two adjacent display devices 40. The angle adjustment component 1 includes a telescopic mechanism 10, an angle pad 20 and a pulling mechanism 30 arranged sequentially along the reference direction X. The telescopic mechanism 10 and the pulling mechanism 30 are respectively installed on the two display devices 40.

[0020] like Figures 1 to 4 The telescopic mechanism 10 includes a first mounting base 11, a transmission device 12, and a locking component 13. The first mounting base 11 is connected to one of the display devices 40. The transmission device 12 is connected to both the first mounting base 11 and an angle pad 20. When the angle pad 20 pushes the transmission device 12, the transmission device 12 can move relative to the first mounting base 11. The locking component 13 is slidably connected to the first mounting base 11 in the reference direction X. The locking component 13 can slide on the first mounting base 11 in the forward direction of the reference direction X or in the reverse direction, i.e., the sliding direction is parallel to the reference direction X. The transmission device 12 and the locking component 13 are movably connected. After the transmission device 12 is pushed by the angle pad 20, the transmission device 12 moves relative to the first mounting base 11 and drives the locking component 13 to move.

[0021] like Figure 2 , Figure 3 and Figure 12 The angle pad 20 has a first connecting surface 21 and a second connecting surface 22 arranged opposite to each other and having a preset angle. The first connecting surface 21 and the second connecting surface 22 are respectively connected to two adjacent display devices 40. The preset angle is the angle between the two display devices 40. For example, if the preset angle of the angle pad 20 is 5°, then after the two adjacent display devices 40 abut against the first connecting surface 21 and the second connecting surface 22 respectively, the angle between the two display devices 40 is also 5°; if the preset angle of the angle pad 20 is 18°, then after the two adjacent display devices 40 abut against the first connecting surface 21 and the second connecting surface 22 respectively, the angle between the two display devices 40 is also 18°. By changing the angle pad 20 with different preset angles, the angle between two adjacent display devices 40 can be precisely controlled. This angle control process no longer relies on the installation experience and installation techniques of the installer, but on the preset angle of the angle pad 20, making the angle control between the two adjacent display devices 40 more controllable.

[0022] The pulling mechanism 30 is connected to another display device 40, and one end of the pulling mechanism 30 is detachably connected to the locking member 13. The pulling mechanism 30 can give the locking member 13 a force toward the reference direction X, forcing the two adjacent display devices 40 to clamp the angle pad 20, so that the two display devices 40 maintain the aforementioned angle.

[0023] like Figure 5 and Figure 6During the installation and debugging of the angle adjustment component 1, the first mounting base 11 and the pulling mechanism 30 are first set on the two display devices 40 respectively, and the angle pad 20 is set on the display device 40 on which the first mounting base 11 is installed. When the angle pad 20 is installed, the angle pad 20 will touch and push the transmission device 12. The transmission device 12 drives the locking component 13 to slide relative to the first mounting base 11. The smaller the preset angle of the angle pad 20, the greater the sliding distance of the locking component 13 driven by the transmission device 12 away from the reference direction X. Conversely, the larger the preset angle of the angle pad 20, the smaller the sliding distance of the locking component 13 driven by the transmission device 12 away from the reference direction X. This allows the angle pad 20 to automatically adapt to different preset angles, so that when the pulling mechanism 30 tightens the locking component 13, it can lock the two adjacent display devices 40.

[0024] Specifically, let point a be the connection between the telescopic mechanism 10 and its corresponding display device 40, and point b be the connection between the pulling mechanism 30 and its corresponding display device 40. The length of the pulling device 33 is fixed. When the preset angle of the angle pad 20 is at a small value (assuming the preset angle is 0~5°), the distance between point a and point b is N. The end of the pulling mechanism 30 is closer to the opposite direction of the reference direction X. To ensure that the end of the pulling mechanism 30 is tightened and locked with the locking component 13, the locking component 13 must also move closer to the opposite direction of the reference direction X. Therefore, the transmission device 12 drives the locking component 13 to slide a large distance away from the reference direction X. The distance between the locking component 13 and the pulling mechanism 30 is relatively large. When the preset included angle of the angle pad 20 is a large value (assuming the preset included angle is 15~30°), the distance between point a and point b is M. Obviously, M is greater than N. This causes the end of the pulling mechanism 30 to be closer to the positive direction of the reference direction X (that is, the direction pointed to by the reference direction X). In order to ensure that the end of the pulling mechanism 30 is tightened and locked with the locking component 13, the locking component 13 must also be moved closer to the positive direction of the reference direction X. Therefore, the sliding distance of the locking component 13 driven by the transmission device 12 away from the reference direction X is small, and the distance between the transmission device 12 and the locking component 13 and the pulling mechanism 30 is small, so as to compensate for the distance MN.

[0025] Furthermore, such as Figure 4 The angle pad 20 has a mounting hole 24, which penetrates the first connecting surface 21 and the second connecting surface 22. The end of the pulling mechanism 30 passes through the mounting hole 24. Figure 3 , Figure 9 and Figure 12The end of the angle pad 20 is provided with a guide component 23 arranged around the axis of the mounting hole 24. The guide component 23 has a first guide slope 231, which is inclined to the radial plane of the mounting hole 24. Correspondingly, the end of the transmission device 12 is provided with a second guide slope 123, such as... Figure 13 The second guide slope 123 is set opposite to the first guide slope 231. During the process of the angle pad 20 pushing the transmission device 12, the first guide slope 231 slides against the second guide slope 123. When the installer installs the angle pad 20 onto the display device 40, the angle pad 20 pushes the transmission device 12 in the opposite direction of the reference direction X. The first guide slope 231 on the angle pad 20 pushes the second guide slope 123 of the transmission device 12, forcing the transmission device 12 to rotate relative to the first mounting base 11 around the reference direction X. At the same time, the transmission device 12 also moves relative to the first mounting base 11 in the opposite direction of the reference direction X. When the transmission device 12 moves, it will drive the locking component 13 to slide relative to the first mounting base 11 in the opposite direction of the reference direction X. This makes both the transmission device 12 and the locking component 13 move away from the pulling mechanism 30. More specifically, the angle pads 20 with different preset angles have different tilt angles and slope lengths of their first guide slopes 231. For example, the angle pads 20 with smaller preset angles force the transmission device 12 to rotate a larger angle relative to the first mounting base 11 around the reference direction X, while the angle pads 20 with larger preset angles force the transmission device 12 to rotate a smaller angle relative to the first mounting base 11 around the reference direction X.

[0026] In this embodiment, both the transmission device 12 and the locking component 13 are cylindrical structures, such as... Figures 13 to 15 The transmission device 12 is sleeved on the outside of the locking component 13. The inner wall surface of the transmission device 12 is provided with a first internal thread 121, and the outer wall surface of the locking component 13 is provided with a first external thread 131 that engages with the first internal thread 121. Based on the above description, the transmission device 12 rotates under the pushing of the angle pad 20. The first internal thread 121 drives the first external thread 131 to move together, forcing the locking component 13 to slide relative to the first mounting seat 11 in the opposite direction of the reference direction X. The outer wall surface of the transmission device 12 is provided with a second external thread 122, and the first mounting seat 11 has a second internal thread 111 that engages with the second external thread 122. This allows the transmission device 12 to move relative to the first mounting seat 11 in the opposite direction of the reference direction X during its rotation around the reference direction X, through the engagement of the second external thread 122 and the second internal thread 111.

[0027] To lock the transmission device 12 and locking component 13 after the angle pad 20 is installed, and to prevent the transmission device 12 and locking component 13 from moving relative to the first mounting base 11, the guide component 23 is provided with a limiting protrusion 232 located at the end of the first guide slope 231, such as... Figure 9 The transmission device 12 is provided with a limiting groove 124 located at the end of the second guide slope 123. When the limiting protrusion 232 slides to the end of the second guide slope 123, the limiting protrusion 232 will be embedded in the limiting groove 124. The limiting protrusion 232 and the limiting groove 124 can prevent the angle pad 20 from rotating relative to the transmission device 12. In addition, the telescopic mechanism 10 includes a first elastic member 14. The two ends of the first elastic member 14 abut against the first mounting base 11 and the transmission device 12, respectively. When the angle pad 20 needs to be replaced, the installer only needs to manually hold the angle pad 20 and apply force to force the angle pad 20 to move in the reference direction X. During the movement of the angle pad 20 away from the transmission device 12, the first elastic member 14 recovers its deformation from the compressed state. The first elastic member 14 pushes the transmission device 12 to move relative to the first mounting base 11 in the reference direction X. During this process, the limiting protrusion 232 will exit from the limiting groove 124.

[0028] like Figure 9 and Figure 10 The pulling mechanism 30 includes a second mounting base 31, a locking rod 32, and a pulling device 33. The second mounting base 31 is used to connect the display device 40. The locking rod 32 is slidably connected to the second mounting base 31. The end of the locking rod 32 is provided with a hook 321. The locking component 13 is provided with a hook groove 132. The hook 321 is detachably hooked to the hook groove 132. The locking component 13 has a connecting hole 133. The side wall of the connecting hole 133 is provided with a clearance groove 134 that passes through the opening of the connecting hole 133. The hook 321 at the end of the locking rod 32 can pass through the clearance groove 134 and enter the connecting hole 133. When the locking rod 32 is rotated by force, the hook 321 can be aligned with the hook groove 132. At the same time, the hook 321 and the clearance groove 134 are misaligned, thus realizing the hook connection between the locking rod 32 and the locking component 13. The pulling device 33 is located between the second mounting base 31 and the locking rod 32. The pulling device 33 has a through hole 331, and the locking rod 32 is slidably inserted through the through hole 331. One end of the locking rod 32 is provided with the aforementioned hook 321, and the other end of the locking rod 32 is provided with a knob 322. The pulling device 33 is threadedly connected to the second mounting base 31. The pulling device 33 rotates relative to the second mounting base 31 to push the knob 322 of the locking rod 32, so that the locking rod 32 slides relative to the second mounting base 31 along the reference direction X. In this way, the hook 321 of the locking rod 32 can pull the locking component 13 and provide a force along the reference direction X to the locking component 13, so that the two display devices 40 have a tendency to move towards each other.

[0029] The outer wall of the first mounting base 11 is provided with a first rotating shaft 112. The first mounting base 11 is sway-connected to one of the display devices 40 through the first rotating shaft 112. The outer wall of the second mounting base 31 is provided with a second rotating shaft 311. The second mounting base 31 is sway-connected to another display device 40 through the second rotating shaft 311. When the preset included angle of the angle pad 20 is not 0°, the first mounting base 11 will swing relative to the display device 40 at a certain angle around its first rotating shaft 112. Similarly, the second mounting base 31 will swing relative to the display device 40 at a certain angle around its second rotating shaft 311.

[0030] like Figure 16 The display device 40 used for mounting the angle pad 20 is also provided with a hook 41 movably connected to the display device 40. A second elastic member 42 is provided between the hook 41 and the display device 40. When the angle pad 20 is placed on the display device 40, the hook 41 engages with the side of the angle pad 20. The side of the angle pad 20 can be provided with a slot or other structure for engaging with the hook 41, depending on the actual situation. The elastic force of the second elastic member 42 drives the hook 41 to engage with the angle pad 20. When it is necessary to remove the angle pad 20, the installer can apply force to press the hook 41 to compress the second elastic member 42, forcing the hook 41 to disengage from the angle pad 20. Of course, in some optional embodiments, a button 411 can also be provided on one side of the hook 41 so that the installer can press the hook 41.

[0031] Example 2 The difference between this embodiment and Embodiment 1 is that a first guiding device is provided between the inner wall surface of the transmission device 12 and the outer wall surface of the locking component 13. The first guiding device includes a first guide rail and a first slider. The first guide rail is spiral-shaped, and the first slider is slidably connected to the first guide rail. One of the first guide rail and the first slider is located on the inner wall surface of the transmission device 12, and the other is located on the outer wall surface of the locking component 13. Based on the structure of the first guiding device, the transmission component can also rotate around the reference direction X and drive the locking component 13 to slide relative to the first mounting base 11 in the opposite direction of the reference direction X.

[0032] Similarly, a second guiding device is provided between the outer wall of the transmission device 12 and the inner wall of the first mounting base 11. The second guiding device includes a second guide rail and a second slider. The second guide rail is helical, and the second slider is slidably connected to the second guide rail. One of the second guide rail and the second slider is located on the inner wall of the first mounting base 11, and the other is located on the outer wall of the transmission device 12. Based on the structure of the second guiding device, the transmission device 12 can also move relative to the first mounting base 11 in the opposite direction of the reference direction X while rotating around the reference direction X.

[0033] Example 3 like Figure 17To address the same technical problem, this embodiment also provides a display device 100, including the aforementioned angle adjustment component 1 and multiple display devices 40. Each display device 40 includes an LED display module and a housing. The LED display module is disposed in the housing. The first mounting base 11 of the angle adjustment component 1 is disposed in the housing of one of the display devices 40, and the second mounting base 31 is disposed in the housing of another display device 40. Adjacent display devices 40 can be connected to each other via multiple angle adjustment components 1 to ensure a stable connection.

[0034] In summary, the angle adjustment assembly 1 includes a telescopic mechanism 10, an angle pad 20, and a pulling mechanism 30. The telescopic mechanism 10 and the pulling mechanism 30 are respectively located on two adjacent display devices 40. The transmission device 12 of the telescopic mechanism 10 can drive the locking component 13 to slide relative to the first mounting base 11 under the pushing action of the angle pad 20. The smaller the preset angle between the first connecting surface 21 and the second connecting surface 22 of the angle pad 20, the greater the sliding distance of the locking component 13 driven by the transmission device 12 away from the reference direction X, so as to automatically adapt to the length of the pulling mechanism 30 and the angle pads 20 with different preset angles. The end of the pulling mechanism 30 is detachably connected to the locking component 13, thereby locking the two adjacent display devices 40.
