Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0028] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0029] Combination Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a concealed rotatable and detachable structure provided in an embodiment of the present invention. The concealed rotatable and detachable structure includes: a quick-release mechanism 10, a vertical plane rotation mechanism 20, a forward tilt and backward tilt mechanism 30, and a horizontal plane rotation mechanism 40; wherein, the vertical plane rotation mechanism 20 is detachably connected to the quick-release mechanism 10; the vertical plane rotation mechanism 20, the forward tilt and backward tilt mechanism 30, and the horizontal plane rotation mechanism 40 are connected in sequence, and the quick-release mechanism 10, the vertical plane rotation mechanism 20, and the forward tilt and backward tilt mechanism 30 are all disposed in the groove 60 of the back cover of the display.

[0030] Combination Figures 3 to 5As shown, in this embodiment, when quick installation and removal of the monitor are required, the quick-release mechanism 10 can be used in conjunction with the vertical plane rotation mechanism 20 for installation and removal. The vertical plane rotation mechanism 20 is used to fix the monitor and allows the monitor to rotate freely in the vertical plane, ensuring that the angle of the monitor in the vertical plane can be freely adjusted during use. The tilt-forward and tilt-back rotation mechanism 30 allows the monitor to be tilted forward or backward. If the monitor is equipped with the tilt-forward and tilt-back rotation mechanism 30, the monitor can be tilted backward or forward to adapt to the usage angle of different users.

[0031] The horizontal plane rotation mechanism 40 can control the monitor to rotate freely within the horizontal plane, that is, to rotate in a fan-shaped range within the same horizontal plane. If the monitor content cannot be viewed from the current viewing angle, the left and right horizontal angles of the monitor can be adjusted by rotating it left and right to ensure that the user can view the monitor content. This rotation can be flexibly adjusted. When the vertical plane rotation mechanism 20, the forward and backward tilt rotation mechanism 30, and the horizontal plane rotation mechanism 40 are combined, the monitor can be adjusted in three degrees of freedom, which can be applied to various scenarios in actual use.

[0032] Combination Figure 6 and Figure 7 As shown, in one embodiment, the quick-release mechanism 10 includes a fixed plate 11 and a sliding block 12 slidably disposed on the fixed plate 11. A reset member 13 for resetting is disposed between the fixed plate 11 and the sliding block 12. An extension 21 is disposed on the vertical plane rotation mechanism 20, and a stop block 14 is disposed on the sliding block 12. The stop block 14 is used to stop the extension 21 at a limited position and to stop stopping the extension 21 when the reset member 13 is pressed and pushes the stop block 14 away from the limited position.

[0033] In this embodiment, the quick-release mechanism 10 is mainly divided into two parts: a fixed plate 11 and a sliding block 12. The fixed plate 11 is fixed to the display and can be understood as the base of the quick-release mechanism 10. The sliding block 12 is disposed on the fixed plate 11 and can slide in cooperation with the reset member 13 disposed between the fixed plate 11 and the sliding block 12. In addition, the vertical plane rotation mechanism 20 is provided with an extension 21. The extension 21 can be a limiting plate structure extending outward from the vertical plane rotation mechanism 20, which can cooperate with the stop block 14 disposed on the sliding block 12. The stop block 14 is used to stop the extension 21 at the limiting position and to stop the extension 21 when the reset member 13 is pressed and pushes the stop block 14 away from the limiting position.

[0034] For example, when the monitor needs to be installed, the reset member 13 is pressed and pushes the stop block 14 away from the limit position. At this time, the extension 21 is pushed into the limit position. After the extension 21 is fixed in the limit position, the reset member 13 is released. The reset member 13 releases pressure and pushes the stop block 14 into the limit position, so that the stop block 14 stops the extension 21. The monitor and the vertical plane rotation mechanism 20 are now fixed. When the monitor needs to be disassembled, pressure is applied to the reset member 13. At this time, the reset member 13 is pressed and pushes the stop block 14 away from the limit position, pushing the vertical plane rotation mechanism 20 so that the extension 21 is away from the limit position. After the extension 21 is away from the limit position, the pressure is released to the reset member 13. The reset member 13 resets and pushes the stop block 14 back into the limit position. At this time, the monitor has been disassembled and the quick-release mechanism 10 has returned to the initial state.

[0035] In one embodiment, the reset member 13 is a spring, with one end of the spring disposed on the fixed plate 11, and the sliding block 12 is provided with a supporting part 15 that abuts against the other end of the spring.

[0036] In this embodiment, the spring serves as a reset mechanism; of course, other reset components can be used instead, and this is not limited here. The quick-release mechanism 10 in this embodiment is provided with two reset components 13, namely two springs. One end of the spring is set on the fixed plate 11, and the fixed plate 11 is provided with a limiting post corresponding to accommodate one end of the spring. In this way, the spring will not fall off or deviate during use. The sliding block 12 is provided with a supporting part 15 that abuts against the other end of the spring. When the spring is pressed, it can be understood as pressing the supporting part 15, thereby pushing the spring to compress, and then driving the stop block 14 away from the limiting position, which facilitates the installation and removal of the extension part 21.

[0037] It should be noted that the number of reset pieces 13 can be adjusted according to the actual application, but the number of reset pieces 13 should not be too many or too few. If the number is too many, a greater force may be required to apply pressure to the supporting part 15, or the supporting part 15 may not be able to be pushed. If the number is too few, it may be impossible to limit the extension part 21 or the limiting part may not be tight enough, which may cause the vertical plane rotation mechanism 20 to fall off during use. Therefore, an appropriate number can be set after sufficient testing.

[0038] In one embodiment, the sliding block 12 is provided with a strip-shaped hole 16 along its sliding direction, and a limiting member 17 fixed to the fixing plate 11 is provided in the strip-shaped hole 16. An operating rod 18 for operating the sliding block 12 is provided on the surface of the sliding block 12.

[0039] In this embodiment, the sliding block 12 slides in a straight line, and a strip hole 16 is provided along its sliding direction. A limiting member 17 fixed to the fixing plate 11 is provided in the strip hole 16. A sliding space is provided in the strip hole 16. When pressure is applied or released to the supporting part 15, the limiting member 17 moves accordingly within the sliding space. Multiple strip holes 16 can be provided, and each strip hole 16 corresponds to one limiting member 17. After passing through the strip hole 16, the limiting member 17 is fixed to the limiting groove extending upward from the fixing plate 11. The limiting member 17 can be a screw or other fixable parts. The purpose of providing the strip hole 16 and the limiting member 17 is to guide the sliding direction of the sliding block 12. After the limiting member 17 is fixed to the fixing plate 11, it slides in the strip hole 16 in conjunction with the supporting part 15. To facilitate the installation and removal of the monitor, a sufficiently long operating lever 18 is provided on the surface of the sliding block 12 for the user to apply or release pressure. The force applied or released to the operating lever 18 will be transmitted to the supporting part 15, thereby achieving the application or release of pressure on the entire quick-release mechanism 10. Preferably, the length of the operating lever 18 can be adaptively adjusted according to the depth of the groove 60 of the monitor, in order to make it easier for installers to install and remove the monitor.

[0040] In one embodiment, the vertical plane rotation mechanism 20 includes a base 22 and a first rotation shaft 23 rotatably connected to the base 22 in a vertical plane, and the forward tilting and backward tilting mechanism 30 is fixed to the first rotation shaft 23.

[0041] In this embodiment, the base 22 is used to fix the display and serves as a support base for the display. The first rotating shaft 23 is connected to the base 22, and the base 22 can rotate around the first rotating shaft 23 in a vertical plane. The rotation of the base 22 also drives the display to rotate. Multiple friction parts are provided on the first rotating shaft 23. When the first rotating shaft 23 stops rotating, the friction parts rub against each other to fix it, ensuring that the base 22 remains at the current angle after the angle is adjusted. If friction parts are not provided, the base 22 may return to the angle before adjustment as soon as the angle is released due to the gravity of the display after the angle is manually adjusted. One end of the first rotating shaft 23 is connected to the base 22, and the other end is connected to the tilt-forward and tilt-backward rotation mechanism 30. In this way, the vertical plane rotation mechanism 20 and the tilt-forward and tilt-backward rotation mechanism 30 are connected.

[0042] In one embodiment, the forward tilting and backward tilting mechanism 30 includes a fixed bracket 31 fixed to a first rotating shaft 23, a second rotating shaft 32 rotatably connected to both sides of the fixed bracket 31, and a torsion spring 33 sleeved on the second rotating shaft 32. A horizontal plane rotating mechanism 40 is rotatably connected to the second rotating shaft 32. One end of the torsion spring 33 is fixed to the fixed bracket 31, and the other end of the torsion spring 33 abuts against the horizontal plane rotating mechanism 40.

[0043] In this embodiment, the tilt-forward and tilt-back rotation mechanism 30 includes a fixed bracket 31, a second rotating shaft 32, and a torsion spring 33. The fixed bracket 31 is fixed to the first rotating shaft 23, and the second rotating shaft 32 is rotatably connected to both sides of the fixed bracket 31. The second rotating shaft 32 is also fitted with a torsion spring 33 to provide elastic force. Both ends of the torsion spring 33 extend outward, one end of the torsion spring 33 is fixed to the fixed bracket 31, and the other end of the torsion spring 33 abuts against the horizontal plane rotation mechanism 40. Specifically, the fixed bracket 31 uses the two ends of the second rotating shaft 32 as fulcrums to adjust the tilt-forward and tilt-back angle. Ideally, the torsion spring 33 is used to balance the weight of the display, and the elastic force of the torsion spring 33 is equal to the weight of the display (ideally, the two forces are balanced). The second rotating shaft 32, like the first rotating shaft 23, is provided with multiple friction parts to provide friction force, which is related to human movement. The rotational forces are opposite in direction and equal in magnitude, and the direction of the frictional force changes with the direction of the manual rotational force. This allows the tilt-forward and tilt-back rotation mechanism 30 to remain at the target position after rotation, instead of returning to its original unadjusted state as soon as the force is released. Alternatively, the monitor can be considered a weightless object (gravity and elasticity cancel each other out), in which case only the frictional force of the frictional parts remains. For example, when the monitor is tilted upwards, the manual rotational force is upwards, and the frictional force is opposite to the rotational force. After adjusting the angle, the rotational force is removed, leaving only the frictional force, which holds the tilt-forward and tilt-back rotation mechanism 30 at the currently adjusted angle position. Similarly, when the monitor is tilted downwards, the manual rotational force is downwards, and the frictional force is opposite to the rotational force, which also holds the monitor at the adjusted angle position.

[0044] In one embodiment, the horizontal plane rotation mechanism 40 includes a horizontal rotation component 41 and a connecting rod 43 rotatably connected to the horizontal rotation component 41 in the horizontal plane via a third rotation shaft 42. The front end of the horizontal rotation component 41 is provided with a gripper 44, which is sleeved on the second rotation shaft 32. The rear end of the horizontal rotation component 41 is provided with a rotating disk 45, and the connecting rod 43 is provided with a rotation groove 46 for the rotating disk 45 to rotate.

[0045] In this embodiment, the horizontal plane rotation mechanism 40 includes a horizontal rotation component 41, a third rotation shaft 42, and a connecting rod 43. The front end of the horizontal rotation component 41 is provided with a gripper 44, which is sleeved on both ends of the second rotation shaft 32, serving as support points for the fixed bracket 31 to tilt forward and backward. The second rotation shaft 32 passes through both the fixed bracket 31 and the gripper 44. The third rotation shaft 42 passes through both the connecting rod 43 and the rotating disk 45, allowing for horizontal plane angle adjustment of the display. One end of the connecting rod 43 is provided with a rotation groove 46 for the rotating disk 45 to rotate. After the rotating disk 45 and the rotation groove 46 rotate in cooperation, the angle is fixed by friction parts provided on the third rotation shaft 42. Thus, after adjusting the angle of the horizontal plane rotation mechanism 40, it will not return to its original position when the manual rotation force is removed. It should be noted that the more friction parts provided on the third rotation shaft 42, the greater the friction force, and the greater the rotation force required to adjust the angle. The number of friction parts can be increased appropriately according to the actual situation.

[0046] In one embodiment, a first limiting protrusion 47 is provided on the rotating disk 45, and a second limiting protrusion 48 matching the first limiting protrusion 47 is provided on the rotating groove 46; the hidden rotatable detachable structure also includes an adapter sleeve 70 and a support column 80. The adapter sleeve 70 includes a sleeve body 71 sleeved on the connecting rod 43 and a sub-sleeve 72 disposed on the side of the sleeve body 71, and the support column 80 is disposed inside the sub-sleeve 72.

[0047] In this embodiment, the first limiting protrusion 47 on the rotating disk 45 and the second limiting protrusion 48 on the rotating groove 46 cooperate with each other to limit the horizontal plane adjustment range of the horizontal plane rotation mechanism 40, so that the horizontal rotation component 41 rotates in a fan shape around one end of the connecting rod 43 in the horizontal plane. For example, when the horizontal rotation component 41 keeps rotating to one side, the first limiting protrusion 47 slowly approaches the second limiting protrusion 48. When the first limiting protrusion 47 abuts against the second limiting protrusion 48, the horizontal rotation component 41 can no longer move, and at this time the maximum angle of horizontal rotation is reached.

[0048] Additionally, both the adapter sleeve 70 and the support column 80 are located outside the groove 60. The adapter sleeve 70 includes a sleeve body 71 sleeved on the connecting rod 43 and a sub-sleeve 72 located on the side of the sleeve body 71. The support column 80 is located inside the sub-sleeve 72. It should be noted that the adapter sleeve 70 can be located close to or far from the groove 60. The closer it is to the groove 60, the greater the supporting force provided by the support column 80; the farther it is from the groove 60, the smaller the supporting force provided by the support column 80. This can be adjusted according to the actual situation. The sub-sleeve 72 is provided to facilitate the installation of the support column 80 and to allow for flexible adjustment of the position of the support column 80. Of course, it is also feasible to directly weld the support column 80 to the connecting rod 43. It can be set according to requirements.

[0049] In one embodiment, the concealed rotatable and detachable structure further includes a decorative element 50, which includes a first decorative element 51 and a second decorative element 52. The second decorative element 52 has a hollowed-out center. The first decorative element 51 is fastened to the hollowed-out portion of the second decorative element 52. A gap for heat dissipation is provided between the first decorative element 51 and the back cover of the display. The second decorative element 52 covers the groove 60 of the back cover of the display. A plurality of heat dissipation holes 53 are provided on the surface of the second decorative element 52. A limiting hole 54 is provided on the first decorative element 51 for the horizontal plane rotation mechanism 40 to pass through and for providing forward and backward tilting space.

[0050] In this embodiment, during actual use, the decorative piece 50 covers the quick-release mechanism 10, the vertical plane rotation mechanism 20, and the tilt-forward and tilt-back rotation mechanism 30, thus hiding them within the groove 60, making the back cover look simpler and more visually appealing. The decorative piece 50 can be understood as part of the display back cover. When the decorative piece 50 covers the groove 60, the display back cover is in a complete state. If the decorative piece 50 is removed, the quick-release mechanism 10, the vertical plane rotation mechanism 20, and the tilt-forward and tilt-back rotation mechanism 30 located within the groove 60 can be seen.

[0051] Specifically, the second decorative piece 52 has a hollowed-out central section. In this embodiment, a circular ring structure is used. Of course, other structural designs (such as a rectangular hollowed-out central section) can also be used depending on the actual usage. The outer edge of the first decorative piece 51 is provided with a first locking buckle, and the hollowed-out portion of the second decorative piece 52 is provided with a second locking buckle that matches the first locking buckle. When the second decorative piece 52 and the first decorative piece 51 are fastened together, simply align the hollowed-out portion of the second decorative piece 52 with the entire first decorative piece 51, and simultaneously align the first locking buckle and the second locking buckle accordingly. Press the second decorative piece 52 downwards and then rotate it so that the first locking buckle and the second locking buckle are fastened together. The first decorative piece 51 is provided with screw holes, through which the first decorative piece 51 can be connected and fixed to the tilting and rotating mechanism 30. The heat dissipation gap between the first decorative piece 51 and the back cover of the display is intended to enable the display to dissipate heat more quickly during operation. In actual use, the groove 60 of the display also contains a large number of wires; therefore, a certain space is required for heat dissipation. To further dissipate heat, heat dissipation holes 53 can also be opened on the surface of the second decorative piece 52. The more heat dissipation holes 53 are opened, the stronger the auxiliary heat dissipation effect will be.

[0052] Furthermore, the outer edge of the second decorative piece 52 is provided with a third locking buckle. The second decorative piece 52 is fixed to the back cover of the monitor by the third locking buckle. During installation, it is only necessary to align the third locking buckle with the slot on the back cover of the monitor and then apply pressure to the second decorative piece 52. If it is necessary to disassemble the second decorative piece 52, it can be disassembled through the disassembly slot provided on the outer edge of the second decorative piece 52. That is, use a professional tool to pry open the disassembly slot. After prying, the second decorative piece 52 is separated from the back cover of the monitor.

[0053] Additionally, the first decorative piece 51 is provided with a limiting hole 54 for the horizontal plane rotation mechanism 40 to pass through and to provide space for tilting forward and backward. The purpose of setting the limiting hole 54 here is to limit the tilting angle of the monitor. If it is not limited, the tilting angle may be too large, which may cause the tilting rotation mechanism 30 to be unable to bear the weight of the monitor and break. Of course, the opening area of ​​the limiting hole 54 should be as large as possible to ensure a larger tilting angle, so that it can be applied to more scenarios.

[0054] In this embodiment of the invention, a display is also provided, including a display back cover and a hidden rotatable detachable structure as described above disposed on the display back cover; the hidden rotatable detachable structure is hidden in the groove 60 of the display back cover, which improves the overall appearance simplicity of the display.

[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.

[0056] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, or article that comprises a list of elements, or includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, or article, are included. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, or article that includes said element.
