Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more specifically, to a display device and its display bracket. Background Technology

[0002] In related technologies, display brackets are functionally categorized into three types: tilt (forward / backward), pivot (vertical rotation), and swiel (left / right rotation). Each function has an independent structure: the tilt (forward / backward) and pivot functions are located at the top of the column, while the swiel function is located at the bottom. Each function rotates independently within a single plane. This layout cannot achieve multi-angle rotation, limiting the range of adjustment available to the user.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0049] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0050] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0051] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects.

[0052] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0053] This disclosure provides a display device, including a display module, an adapter plate 13, and a display bracket. The adapter plate 13 is used to connect the display module and the display bracket.

[0054] In related technologies, a display stand includes a base, a first motion component mounted on the base, a column mounted on the first motion component, a second motion component mounted on the column, and a third motion component mounted on the second motion component. The first motion component is configured to perform left-right rotation (swing), the second motion component is configured to perform vertical rotation (pivot), and the third motion component is configured to perform forward and backward tilting (tilt). In this structure and motion configuration, the movements of the first, second, and third motion components are independent (the three motion components rotate independently in three different planes). This structural layout cannot achieve multi-angle rotation, resulting in limited adjustable range for the user.

[0055] To address the aforementioned problems, this disclosure provides a novel display bracket structure, see [link to relevant documentation]. Figure 1 The system includes a connection assembly and a bracket body 7. In this example, the connection assembly is mounted on the bracket body 7 and is connected to the display module. The connection assembly is configured to drive the display module to move in multiple directions and fix the position of the display module.

[0056] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 The bracket body 7 includes a base 71 and a column 72. The column 72 is fixedly installed on the base 71, and the connecting assembly is set on the column 72.

[0057] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The connecting assembly includes a spherical gear 1, two lumbar gears 2, and two connecting mechanisms 3, with the two lumbar gears 2 and the two connecting mechanisms 3 connected in a one-to-one correspondence.

[0058] In one example, see Figure 3 , Figure 7 , Figure 8 , Figure 11 as well as Figure 12Each connecting mechanism 3 includes a chassis 4, a turntable 5, and a connecting shaft 6. The chassis 4 is mounted on a column 72, and the turntable 5 is mounted on the chassis 4, with the turntable 5 and chassis 4 connected in a damped manner to allow relative movement between the turntable 5 and chassis 4 under external force. The connecting shaft 6 is mounted on the turntable 5 and fixedly connected to it. A spherical gear 2 is sleeved on the connecting shaft 6 and dampedly engaged with the turntable 5, allowing relative movement between the spherical gear 2 and the connecting shaft 6 under force. Two spherical gears 2 and a spherical gear 1 mesh with each other, and the axes of the two spherical gears 2 are parallel. The line connecting the axis of one spherical gear 2 to the center of the spherical gear 1 is perpendicular to the line connecting the axis of the other spherical gear 2 to the center of the spherical gear 1. The spherical gear 1 is used to connect to the adapter plate 13. In this disclosure, a dual-axis design (the rotation of the waist-face gear around the connecting shaft is one axis, and the rotation of the turntable is one axis) and a free hinge design (meshing of the spherical gear and the waist-face gear) are implemented to realize the free rotation of the spherical gear, and finally realize the multi-angle adjustment of the display module, as well as the integration of the tilt function, the vertical rotation function, and the left and right rotation function.

[0059] In this disclosure, based on the meshing of spherical gear 1 and waist gear 2 (the spherical tooth profile allows for transmission in multiple directions, and the waist gear 2 (which has axial or radial arc-shaped tooth surfaces) enables complex motion transmission in three-dimensional space), and the relative motion between turntable 5 and chassis 4 (the waist gear 2 rotates on a first plane, and turntable 5 rotates on a second plane, with the first and second planes intersecting), the display module can be rotated in various orientations. In other words, this disclosure uses the meshing of spherical and waist gears, as well as the rotation of the spherical gear and the rotation and revolution of the waist gear, to meet the user's scenario of free rotation, improve the user's portable experience, and, in conjunction with the damped connection between turntable 5 and chassis 4, and the damped connection between waist gear 2 and connecting shaft 6, achieves the positioning of the display module.

[0060] In addition, in this disclosure, the drum-shaped teeth of the waist gear 2 can tolerate a certain axial or angular deviation, while the spherical structure of the spherical gear 1 can adapt to this deviation, reduce the assembly accuracy requirements, and reduce the risk of wear or failure caused by installation errors.

[0061] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 Adapter board 13 is a VESA adapter board. The display module is connected to the VESA adapter board 13. In this example, the VESA adapter board can be connected and fixed to the display module by multiple screws.

[0062] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 12The chassis 4 has a circular sliding cavity, the turntable 5 is set inside the circular sliding cavity, and the edge of the turntable 5 is dampedly connected to the chassis 4 (it can be understood that the edge of the chassis 4 is dampedly connected to the inner wall of the circular sliding cavity).

[0063] In one example, the chassis 4 achieves a damped connection with the turntable 5 by clamping, so that the chassis 4 and the turntable 5 have both positioning functions and the chassis 4 does not restrict the movement of the turntable 5 when the turntable 5 is under force.

[0064] Optional, see Figure 7 , Figure 8 The chassis 4 includes two disc bodies 41 and a chassis fastener for fastening and fixing the two disc bodies 41. In this disclosure, the two disc bodies 41 are defined as a first disc body 42 and a second disc body 43. It can be understood that the chassis 4 includes a first disc body 42, a second disc body 43, and a chassis fastener for fixing the first disc body 42 and the second disc body 43. The chassis 4 has a circular stepped hole 44. Specifically, the first disc body 42 has a first sub-circular stepped hole (the larger end of the first sub-circular stepped hole is circular, and the smaller end of the first sub-circular stepped hole is concentric with the larger end of the first sub-circular stepped hole), and the second disc body 43 has a second circular sub-circular stepped hole of the same size. When the first disc 42 and the second disc 43 are engaged, the large ends of the first sub-circular stepped holes and the second sub-circular stepped holes approach and fit together. After engagement, the first and second sub-circular stepped holes form a circular sliding cavity, and the large ends of the first and second sub-circular stepped holes fit together to form a limiting slide 45 for the circular sliding cavity. The edge of the turntable 5 is located within the limiting slide 45 and is dampedly connected to the limiting slide 45. The term "same dimensions" in this disclosure refers to the difference between the dimensions of the first and second sub-circular stepped holes being within 5%, allowing for manufacturing errors. Using the structure of the chassis 4 in this example results in low cost and facilitates assembly and disassembly.

[0065] In other examples, other methods can also be used to achieve the damped connection between chassis 4 and turntable 5.

[0066] In one embodiment of this disclosure, the chassis fixing component can be a bolt, and the disc body 41 can have multiple first fixing holes. The bolt passes through the first fixing holes on two disc bodies 41 to fix the two disc bodies 41. Using bolts for fixing is low-cost and simple to operate. Of course, in other embodiments, the chassis fixing component can also be other structures that can achieve the fixing function.

[0067] In one embodiment of this disclosure, the edge of the turntable 5 can be completely disposed within the limiting slide 45 and dampedly connected to the limiting slide 45. In other words, the thickness of the turntable 5 is slightly greater than the thickness of the limiting slide 45, thereby achieving that the edge of the turntable 5 is located within the limiting slide 45 and dampedly connected to it.

[0068] In another embodiment of this disclosure, see Figure 11 and Figure 12 The edge of the turntable 5 can be a structure that matches the circular sliding cavity. In other words, a protrusion 51 is provided at the corresponding position of the limiting slide 45 on the edge of the turntable 5. The protrusion 51 is embedded in the limiting slide 45 and cooperates with the limiting sliding damping. After being subjected to external force, the protrusion 51 can slide within the limiting slide 45. In addition, the edge of the turntable 5 corresponding to the small end of the circular stepped hole is damped and cooperates with the small end of the circular stepped hole. In this way, double damping limiting can be achieved, which can ensure the fixed position of the display module when no external force is applied, and ensure the stability of the entire display device. In one example, the protrusion 51 can be a ring structure, so that the friction between the protrusion 51 and the limiting slide 45 is more uniform, which is beneficial to ensuring the stability of the display device. In another example, multiple protrusions 51 can also be evenly arranged to form an intermittent ring structure.

[0069] In this embodiment, the turntable 5 has a mounting cavity, and the connecting shaft 6 is fixedly disposed within the mounting cavity. In one example, the turntable 5 can achieve a fixed connection with the connecting shaft 6 by clamping.

[0070] Optional, see Figure 11 and Figure 12 The turntable 5 includes two circular rotating bodies 52 and a turntable fixing member that fastens and secures the two circular rotating bodies 52. In this disclosure, the two circular rotating bodies 52 are defined as a first circular rotating body 55 and a second circular rotating body 56. In other words, the turntable 5 includes a first circular rotating body 55 and a second circular rotating body 56, and a turntable fixing member that fastens and secures the first circular rotating body 55 and the second circular rotating body 56. See also... Figure 15The first circular rotating body 55 has a first through hole 53. The side of the first circular rotating body 55 closest to the second circular rotating body 56 has two notches 54, distributed on both sides of the first through hole 53 and communicating with it (in other words, the thickness of the first circular rotating body 55 at the notch 54 is less than the thickness of other areas of the first circular rotating body 55, and the opening of the notch 54 extends to the first through hole 53). The structure of the second circular rotating body 56 is the same as that of the first circular rotating body 55. When the first circular rotating body 55 and the second circular rotating body 56 are engaged, the two notches 54 on the first circular rotating body 55 correspond one-to-one with the two notches 54 on the second circular rotating body 56, forming a fixing groove. The two fixing grooves and the two first through holes 53 form a mounting cavity for mounting and fixing the connecting shaft 6. Using the structure of the turntable 5 in this disclosure results in low cost and simple assembly.

[0071] Optionally, in one example, the two ends of the connecting shaft 6 are respectively clamped in two fixed slots, and the connecting shaft 6 is damped in engagement with the fixed slots. The spur gear 2 is sleeved on the connecting shaft 6 and is damped in engagement with the connecting shaft 6. The damping between the spur gear 2 and the connecting shaft 6 is less than the damping between the connecting shaft 6 and the fixed slots. In this way, when subjected to external force, the spur gear 2 can rotate while the connecting shaft 6 remains fixed. In another example, see... Figure 16 The connecting shaft 6 has two planar cross-sections 9 extending along its axial direction (the number of planar cross-sections 9 is two, each corresponding to a notch 54, the groove surface of the notch 54 being a plane adapted to the planar cross-section 9; in this disclosure, the groove surface refers to the side facing the circular rotating body 52; for example, in the first circular rotating body 55, the groove surface of the notch 54 is the side facing the second circular rotating body 56. In other examples, the number of planar cross-sections 9 can be one, three, four, etc.). In this way, by using contact between the planes, the connecting shaft 6 can be prevented from rotating when subjected to external force, ensuring the stability of the entire display device.

[0072] Optionally, the circular rotating body 52 has sub-protrusions 57, and the sub-protrusions 57 on the two circular rotating bodies 52 form a protrusion 51.

[0073] In one embodiment of this disclosure, the turntable fixing component can be a bolt, and the circular rotating body 52 can have multiple second fixing holes. The bolts fix the two circular rotating bodies 52 through the second fixing holes on the two disc bodies 41. Using bolts for fixing is low-cost and simple to operate. Of course, in other embodiments, the turntable fixing component can also be other structures that can achieve the fixing function.

[0074] In other examples, other methods can also be used to fix the turntable 5 to the connecting shaft 6.

[0075] In one embodiment of this disclosure, the axial direction of the connecting shaft 6 is parallel to the radial direction of the turntable 5, and the axial direction of the waist gear 2 is parallel to the radial direction of the turntable 5.

[0076] In one embodiment of this disclosure, there is damping between the waist gear 2 and the connecting shaft 6. The damping satisfies the following conditions: when the waist gear 2 is subjected to an external force, the waist gear 2 can rotate on the connecting shaft 6 (the connecting shaft 6 is fixed), and after the external force is removed, the waist gear 2 can be fixed (when subjected to external forces such as gravity or inertia from the display module, the waist gear 2 can be fixed), thereby achieving the locking of the waist gear 2.

[0077] In one example, see Figure 8 A spring plate 11 can be added between the waist-shaped gear 2 and the connecting shaft 6 to increase damping. In this example, the connecting shaft 6 includes a shaft and limiting structures 10 disposed on the shaft and located at both ends of the shaft. One limiting structure 10 is fixedly connected to the connecting shaft 6 (for example, the limiting structure 10 is integrally formed with the connecting shaft 6), and the other limiting structure 10 is detachably connected to the connecting shaft 6 (for example, the other limiting structure 10 can be a nut). The waist-shaped gear 2 is located between the two limiting structures 10. A spring plate 11 is sleeved between the limiting structure 10 and the waist-shaped gear 2 on the connecting shaft 6. The spring plate 11 abuts against the limiting structure 10 and the waist-shaped gear 2 to provide damping for the rotation of the waist-shaped gear 2. The number of spring plates 11 can be one, two, three, etc.

[0078] In one example, to reduce the overall size of the structure, see [reference needed]. Figure 11 Both ends of the waist-shaped gear 2 are provided with clearance springs 11 and clearance notches of the limiting structure 10, with the springs 11 abutting against the end faces of the clearance notches. In this disclosure, the waist-shaped gear 2 is provided with a double-layer damping structure. One is the damping between the waist-shaped gear 2 and the shaft, and the other is the damping using the springs 11 between the limiting structure 10 and the end faces of the waist-shaped gear 2. The double damping setting is more conducive to ensuring the stability of the movement of the waist-shaped gear 2, and can ensure that the waist-shaped gear 2 can remain fixed when the display device is not subjected to external force, thus maintaining the fixed position of the display module.

[0079] In one embodiment of this disclosure, the two spherical gears 2 are parallel to each other, and the line connecting the axis of one spherical gear 2 to the center of the spherical gear 1 is perpendicular to the line connecting the axis of the other spherical gear 2 to the center of the spherical gear 1. It is understood that the planes containing the two turntables 5 are perpendicular. Both spherical gears 2 mesh with the spherical gear 1.

[0080] This solution consists of three systems. First, the display module can freely rotate between a spherical gear 1 and two oblong gears 2 (oblong gears 2 are fixed). This rotation is vertical, and the rotation angle can be limited as needed. Second, two oblong gears 2 each rotate around a connecting shaft 6, enveloping the spherical gear 1 (oblong gears 2 rotate), enabling left-right rotation, with the rotation angle also limited as needed. Third, the rotation of a turntable 5 enables forward-backward rotation, with the rotation angle also limited as needed. These three systems work together to achieve large-angle, multi-directional free rotation of the display module.

[0081] In one embodiment of this disclosure, the spherical gear 1 and the adapter plate 13 are connected by a connector. In one example, see [link to example]. Figure 2 and Figure 10 The connector includes a first connecting rod 15, a second connecting rod 14, and multiple connecting fasteners. The first connecting rod 15 is connected to the spherical gear 1, and its other end has a slot. One end of the second connecting rod 14 is connected to the adapter plate 13, and its other end is inserted into the slot of the first connecting rod 15. At the slot, the first connecting rod 15 has a fixing through hole, and the second connecting rod 14 has a fixing groove. One end of the connecting fastener passes through the fixing through hole and is fixed in the fixing groove, which allows for quick fixation of the first connecting rod 15 and the second connecting rod 14. In this disclosure, by inserting the second connecting rod 14 into the first connecting rod 15 and using fasteners to fix the relative positions of the first connecting rod 15 and the second connecting rod 14, the connection between the adapter plate 13 and the rotary support structure is achieved. The structure is simple and easy to assemble and disassemble. Of course, in other examples, other structures can also be used to achieve the connection and fixation.

[0082] In one example, the second connecting rod 14 can be a prism structure. This allows for rotational limitation by the prism, further preventing relative rotation between the first connecting rod 15 and the second connecting rod 14, thus improving the reliability of the connection between the first and second connecting members (for example, the second connecting rod 14 can be a triangular prism, a square prism, a pentagonal prism, etc.). Of course, in other examples, the shapes of the first connecting rod 15 and the second connecting rod 14 can also be cylindrical, etc.

[0083] In one embodiment of this disclosure, the connecting fastener can be a screw, and the fixing through hole and fixing groove can have a threaded structure. Using a threaded fixing method can improve the stability of the connection.

[0084] In one example, the spherical gear 1 can be a complete spherical structure. In other examples, the spherical gear 1 can be an incomplete spherical structure (e.g., a hemispherical structure), which facilitates the connection of the first connector on the plane formed by the spherical gear 1 (incomplete spherical structure).

[0085] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 3 The connecting assembly also includes two support brackets 12; each support bracket 12 is connected to one of the two chassis 4. Each support bracket 12 has a support groove for supporting the spherical gear 1, and the two support brackets 12 are located on either side of the spherical gear 1 (the spherical gear is positioned within the support groove and can slide within it). The maximum size of the support groove is smaller than the diameter of the spherical gear 1 to avoid interfering with its movement. In this example, one support bracket 12 is located below the spherical gear 1, and the other support bracket 12 is located above it, providing support for the spherical gear 1, improving the stability of the entire structure, and ensuring the stability of multi-directional rotational motion transmission.

[0086] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 14 and Figure 9 The side of the column 72 away from the base 71 has a receiving cavity 73. In one example, both spherical gears 2 and two connecting mechanisms 3 are disposed within the receiving cavity 73, which can reduce the size of the display bracket. In another example, both spherical gears 2 and two connecting mechanisms 3 are disposed within the receiving cavity 73, and part of the spherical gear 1 is also located within the receiving cavity 73. In this way, the cavity wall of the receiving cavity 73 can limit the rotation angle of the spherical gear 1 to a certain extent. For example, the rotation angle of the display module can be limited to within 47 degrees to the left or right.

[0087] In one embodiment of this disclosure, the column 72 can be prism-shaped, for example, a triangular prism, a square prism, a pentagonal prism, etc., which are not limited herein. In one example, the column 72 can have a height adjustment function, thus allowing the height of the column 72 to be adjusted as needed, increasing user comfort. In one example, see [link to example]. Figure 13 Multiple pads (not shown in the figure) can be installed on the side of the base 71 away from the column 72. This can reduce the noise generated when the base 71 is placed, increase the friction between the base 71 and the external placement platform, and reduce the probability of the base 71 moving when subjected to external force.

[0088] In one embodiment of this disclosure, the display bracket may further include a limiting member, which can further limit the rotation angle range of the display module. In one example, the limiting member may be a limiting block, which is detachably connected to the display bracket. In this way, the user can adjust the position of the limiting block as needed to meet the limitation of its own rotation range.

[0089] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
