[0002] Display stands allow computer screens and other display devices to float on the desktop, making them more aesthetically pleasing. They also free the display devices from the constraints of a stand, enabling true 360° all-around adjustment. In addition, they reduce the amount of desktop space they take up, increasing the usable desktop space. They are a great companion for many people who work from home or are students.

[0003] However, existing display device brackets have the following drawbacks: the base and support rod of single-arm display device brackets on the market are usually fixedly connected or simply clamped.

[0030] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0034] The following description, in conjunction with the accompanying drawings, further illustrates this application:

[0035] like Figures 1 to 10 As shown, this application provides a display device bracket, including a support component 1 and a connecting component 2. The support component 1 and the connecting component 2 are rotatably connected. The support component 1 is typically used to fix to the surface of a support, and the connecting component 2 is typically used to connect and fix to the display device. By utilizing the rotatable connection between the connecting component 2 and the support component 1, the display direction of the display device can be easily adjusted, allowing users to freely adjust the viewing angle of the display device and improve viewing comfort.

[0036] The support assembly 1 includes a support rod 11 and a support base 12. The two ends of the support rod 11 are connected to the support base 12 and the connecting assembly 2, respectively. The support base 12 is usually used to fix to the surface of the support. The support rod 11 is used to support the display device in the extension direction so as to realize the position change of the display device.

[0037] like Figure 1In the embodiment shown, the main structure of the support base 12 is L-shaped, and the support base 12 has mounting holes 122 on at least one side. The support base 12 can be fixed to the surface of a support such as a wall through the mounting holes 122.

[0038] The support base 12 is provided with a support column 121, and the support rod 11 is adapted to slide or be fixed along the support column 121. By using the support column 121, the entire support rod 11 can move along the length direction of the support column 121, thereby increasing the maximum adjustable range of the entire display device bracket.

[0039] A limiting mechanism 3 is provided on the support column 121. The limiting mechanism 3 is adapted to restrict the support rod 11 from sliding to one side of the limiting mechanism 3, so that the support rod 11 can be stably placed on the support column 121. Since the position of the support rod 11 on the support column 121 is adjustable, and for the purpose of easy adjustment, the support rod 11 is usually connected in the form of a clamp in practical applications. However, under long-term stress, this structure may be difficult to maintain the stability of the support rod 11. Therefore, by setting the limiting mechanism 3, the position of the support rod 11 on the support column 121 can be effectively supported, and the support rod 11 can be prevented from slipping, thereby improving the stable support for the display device.

[0040] like Figures 2 to 4 In the illustrated embodiment, the limiting mechanism 3 includes a limiting ring 31, positioning blocks 32, and fasteners 33. The limiting ring 31 is sleeved on the support column 121, and at least one first mounting channel 311 is provided on the limiting ring 31. An abutment portion 34 is provided on the side of the first mounting channel 311 near the support column 121. The positioning blocks 32 are adapted to be fitted into the first mounting channels 311 one by one. The fasteners 33 are adapted to restrict the positioning blocks 32 within the first mounting channels 311 and abut against the abutment portion 34. The fasteners 33 are adapted to move relative to the positioning blocks 32, so that the abutment portion 34 moves at least radially relative to the limiting ring 31 along the support column 121. The contact portion 34 not only protects the surface of the support column 121 and reduces wear, but also increases the contact area between the limiting ring 31 and the support column 121, thereby increasing static friction and reducing the probability of displacement of the limiting ring 31 under the pressure of the support rod 11. The positioning block 32 can improve the fit stability between the fastener 33 and the contact portion 34, so that the fastener 33 can continuously and stably press the contact portion 34 into contact with the surface of the support column 121. In addition, since there are many forces between the positioning block 32 and the fastener 33, the probability of structural damage is relatively high. Therefore, the setting of the positioning block 32 and the fastener 33 can facilitate maintenance and reduce replacement costs.

[0041] In some embodiments, the first mounting channel 311 is opened in the axial direction along the limiting ring 31, which facilitates the insertion of the positioning block 32 into the first mounting channel 311 from the side of the limiting ring 31.

[0042] In some embodiments, the first installation channel 311 is opened through the limiting ring 31, so that the positioning block 32 can be inserted from both the upper and lower sides of the limiting ring 31, which can improve the ease of installation.

[0043] like Figures 2 to 4 In the embodiment shown, the limiting ring 31 has a second mounting channel 312 on the side of the first mounting channel 311 away from the support column 121 for the fastener 33 to pass through. The second mounting channel 312 is connected to the first mounting channel 311. The fastener 33 is adapted to pass through the second mounting channel 312 and the positioning block 32 and then abut against the contact portion 34. When the fastener 33 passes through the second mounting channel 312 and connects with the positioning block 32, at least part of the fastener 33 is located in the second mounting channel 312. The fastener 33 can restrict the positioning block 32 from leaving the first mounting channel 311, further improving the structural stability.

[0044] In some embodiments, the connection between the fastener 33 and the positioning block 32 is a threaded rod connection, which can improve the stability after relative movement occurs between the fastener 33 and the positioning block 32.

[0045] like Figure 3 In the embodiment shown, the second mounting channel 312 is opened in the radial direction along the limiting ring 31, which facilitates the cooperation between the fastener 33 and the positioning block 32, and at the same time has high cooperation stability and is not prone to movement.

[0046] like Figure 2 In the embodiment shown, the fastener 33 is provided with an operating part 331, which is exposed in the second mounting channel 312. The operating part 331 preferably uses a form such as an internal hexagonal screw hole, which can achieve a hidden installation effect.

[0047] like Figure 5 In the embodiment shown, the contact portion 34 includes a fixed end 341 and a movable end 342. The fixed end 341 is fixedly connected to the limiting ring 31. The contact portion 34 is adapted to deform so that the fixed end 341 and the movable end 342 can move relative to each other. The contact portion can deform under the pressure of the fastener 33, so that the movable end 342 abuts against the surface of the support column 121, thereby generating a large static friction force. Furthermore, by increasing the pressure of the fastener 33, the static friction force can be increased to improve the fixing effect.

[0048] In some embodiments, the deformation of the contact portion 34 can be restored, making it convenient for the limiting ring 31 to be repeatedly disassembled and reassembled.

[0049] like Figure 4In the embodiment shown, the width of the positioning block 32 is greater than the width of the movable end 342, ensuring that the positioning block 32 is fixed on the limiting ring 31 and will not move with the movable end 342.

[0050] like Figure 4 In the illustrated embodiment, the width of the fastener 33 is not greater than the width of the movable end 342, ensuring that the fastener 33 does not interfere with structures other than the movable end 342.

[0051] In some embodiments, the width of the fastener 33 is slightly smaller than the width of the movable end 342, and the fastener 33 can more comprehensively compress the movable end 342, thereby increasing the friction between the movable end 342 and the surface of the support column 121.

[0052] like Figure 5 In the embodiment shown, the contact part 34 and the limiting ring 31 are integrally formed and connected. The contact part is cut off between the movable end 342 and the limiting ring 31, which can improve the connection stability between the contact part 34 and the limiting ring 31, reduce the probability of the contact part 34 being lost, and also reduce the number of parts.

[0053] like Figure 4 In the embodiment shown, the shape of the contact portion 34 near the support column 121 is configured to match the shape of the outer surface of the support column 121.

[0054] In some embodiments, the support column 121 is cylindrical, which facilitates rotation between the support rod 11 and the support column 121, and the contact portion 34 is arc-shaped on the side near the support column 121.

[0055] like Figure 4 In the embodiment shown, the number of contact parts 34 is at least two, and the angle between the line connecting two adjacent contact parts 34 and the central axis of the support column 121 is not less than 90°, which can further increase the contact area between the limiting ring 31 and the support column 121, thereby increasing the static friction, dispersing the force, and effectively reducing the probability of movement of the limiting ring 31.

[0056] like Figure 6 In the embodiment shown, a wire harnessing mechanism 4 is provided on the support rod 11. The wire harnessing mechanism 4 has a wire harnessing channel 41 along the length direction of the support rod 11. The wire harnessing mechanism 4 can be a semi-closed structure with openings at both ends and the sides. It can be closed to form the wire harnessing channel 41 by cooperating with the support rod 11. Alternatively, it can be set as a closed structure with openings only at both ends to directly form the wire harnessing channel 41.

[0057] The support rod 11 has a first fixing port 111 and a second fixing port 112. The wire harness mechanism 4 has a first fixing part 42 and a second fixing part 43. The first fixing part 42 is adapted to slide along the first fixing port 111, and the second fixing part 43 is adapted to slide along the second fixing port 112. The first fixing part 42 is adapted to engage with the first fixing port 111 in a first direction, so that the second fixing part 43 engages with the second fixing port 112 in a second direction. The first fixing part 42 is adapted to deform to release the engagement with the first fixing port 111. By utilizing the mutual linkage of the first fixing part 42 and the second fixing part 43 entering the fixed state, the first fixing part 42 and the second fixing part 43 can cooperate and lock with each other, so that the wire harness mechanism 4 is more securely installed on the support rod 11, effectively reducing the probability of the wire harness mechanism 4 falling off. At the same time, the installation operation is simple and convenient.

[0058] It is worth noting that in the embodiments of this application, the first direction refers to the length direction of the support rod 11. When the first fixing part 42 and the first fixing port 111 are engaged, the first fixing part 42 and the first fixing port 111 cannot disengage in the length direction of the support rod 11. In the embodiments of this application, the second direction refers to the direction perpendicular to the length direction of the support rod 11. When the second fixing part 43 and the second fixing port 112 are engaged, the first fixing part 42 and the first fixing port 111 cannot disengage in the length direction perpendicular to the length direction of the support rod 11.

[0059] like Figure 7 In the embodiment shown, a positioning part 113 is provided in the first fixing port 111 along the first direction. The positioning part 113 is adapted to divide the first fixing port 111 into a connecting area 1111 and a fixing area 1112. The first fixing part 42 is adapted to deform to pass through the positioning part 113, thereby transferring between the connecting area 1111 and the fixing area 1112. It can be understood that when the first fixing part 42 enters the fixing area 1112, the first fixing part 42 and the first fixing port 111 can be engaged in the first direction.

[0060] In some embodiments, the length of the connecting region 1111 is not less than the length of the first fixing part 42, which ensures that the first fixing part 42 can extend from the connecting region 1111 into the first fixing port 111, thereby ensuring that the second fixing part 43 can also extend into the second fixing port 112 at this time, reducing the probability of structural interference.

[0061] In some embodiments, the length of the fixing region 1112 is not less than the length of the first fixing part 42, which ensures that the first fixing part 42 can be fully inserted into the fixing region 1112 to achieve engagement, and the travel of the first fixing part 42 in the fixing region 1112 is less than the engagement depth of the second fixing part 43 and the second fixing port 112, ensuring that the movement of the first fixing part 42 in the fixing region 1112 will not cause the engagement relationship between the second fixing part 43 and the second fixing port 112 to fail, thereby improving the connection stability of the wire harness mechanism 4.

[0062] like Figure 7 In the embodiment shown, the positioning part 113 is provided with a guide slope 1131 on the side near the connecting area 1111. The guide slope 1131 is suitable for guiding the first fixing part 42 from the connecting area 1111 to the fixing area 1112. The guide slope 1131 is used to guide the deformation of the first fixing part 42, reduce the difficulty of operation, and make it easier for the first fixing part 42 to be transferred from the connecting area 1111 to the fixing area 1112.

[0063] like Figure 7 In the embodiment shown, the opening area of ​​the connecting area 1111 is larger than the opening area of ​​the fixed area 1112. An arc-shaped transition is provided between the connecting area 1111 and the fixed area 1112 on the opposite side of the positioning part 113. The main purpose of this design is to reduce the difficulty of operation and make it easier for the first fixing part 42 to be transferred from the connecting area 1111 to the fixed area 1112.

[0064] In some embodiments, the opening of the connecting region 1111 extends in the deformation direction of the first fixing part 42 to increase the area, thereby reducing interference in the deformation process of the first fixing part 42 and reducing the difficulty of operation.

[0065] like Figure 7 In the embodiment shown, the number of second fixing ports 112 is even, and the second fixing ports 112 are symmetrically arranged on both sides of the first fixing port 111 along the length direction of the support rod 11, which can improve the connection stability of the wire harness mechanism 4.

[0066] like Figure 7 In the embodiment shown, the first fixing part 42, the first fixing port 111, the second fixing part 43 and the second fixing port 112 in the first direction are a set of connection structures. Multiple sets of connection structures can be provided on the wire harness mechanism 4 in the width direction of the support rod 11 to further improve the connection stability of the wire harness mechanism 4.

[0067] In some embodiments, the second fixing part 43 is a hook-shaped structure, so that it can engage with the second fixing port 112 in the second direction while moving with the first fixing part 42.

[0068] In some embodiments, the first fixing part 42 is provided with a friction structure on the surface outside the wire harness mechanism 4 to improve the user's ease of operation.

[0069] like Figure 6 In the embodiment shown, the friction structure includes a friction strip 421, which is arranged perpendicular to the mating direction of the first fixing part 42 and the support rod 11. The user can more easily pull the wire harness mechanism 4 into or out of the support rod 11 using the friction strip 421.

[0070] like Figure 8 In the embodiment shown, the support rod 11 includes a clamping part 114, a connecting rod part 115, and a rotating part 116. The clamping part 114 and the rotating part 116 are respectively disposed at both ends of the connecting rod part 115. The clamping part 114 is adapted to be connected to the support column 121, and the rotating part 116 is adapted to be connected to the connecting assembly 2.

[0071] In some embodiments, the clamping part 114 is a clamping structure that can be tightened onto the support column 121 by bolts and nuts.

[0072] like Figure 8 In the embodiment shown, the rotating part 116 includes a first rotating head 1161, a second rotating head 1162, and a third rotating head 1163 sequentially disposed between the connecting rod part 115 and the connecting assembly 2. The rotation planes of the first rotating head 1161, the second rotating head 1162, and the third rotating head 1163 are all perpendicular to each other. The rotating part 116 enables the display device to rotate 360° after connection.

[0073] like Figure 8 In the embodiment shown, the connecting rod 115 includes a first connecting rod 1151 and a second connecting rod 1152, which are parallel to each other. A top rod 1153 is connected between one end of the first connecting rod 1151 and one end of the second connecting rod 1152. The top rod 1153 can overcome the pressure of the first connecting rod 1151 and the second connecting rod 1152 on the connecting component 2 side, thereby supporting the display device.

[0074] In some embodiments, the push rod 1153 may be a gas push rod 1153 or a spring push rod 1153, etc.

[0075] In some embodiments, the connection component 2 includes a connection plate 21 and an even number of extension plates 22, the extension plates 22 being adapted to be connected to both sides of the connection plate 21, the extension plates 22 being adapted to extend in at least a third and a fourth direction, and being adapted to be connected to a display device.

[0076] like Figure 9In the embodiment shown, there are two expansion boards. The main body of the expansion board is a V-shaped structure. After the expansion boards are installed on both sides of the connecting board 21, they can form an X-shaped connection structure, which saves space and materials while accommodating the connection of larger display devices as much as possible.

[0077] like Figure 10 In the embodiment shown, the connecting plate 21 is connected to the rotating part 116 by a plug-in fit and locked by bolts to prevent the connecting plate 21 from detaching. The connecting plate 21 and the expansion plate 22 are connected and locked by multiple sets of bolts and nuts.

[0078] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
