Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment brackets, in particular to a display screen bracket. Background Art

[0002] When using some multimedia devices with display screens, people hope to be able to operate mobile communication devices such as mobile phones more conveniently at the same time. For example, in a car scenario, users sometimes need to operate the display screen on the vehicle's center console, and sometimes need to use a mobile phone. In response to such a situation, a display screen stand has appeared on the market. First, the display screen stand is connected to the display screen, and then a mobile device such as a mobile phone is placed on the display screen stand. In this way, users can conveniently operate the display screen of the multimedia device and mobile devices such as mobile phones.

[0003] In the related art, some display screen stands use a single knob to control the clamp arm to clamp or release the display screen.

[0041] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0042] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0043] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0044] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0045] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a display screen bracket, comprising a first clamping member 1, a second clamping member 2, an active member 3 and a driven member 4. The first clamping member 1 and the second clamping member 2 are used to clamp the display screen together. The active member 3 and the driven member 4 are both connected to at least one of the first clamping member 1 and the second clamping member 2, and the driven member 4 is connected to the active member 3, and the driven member 4 can follow the active member 3 to move, so as to adjust the distance between the first clamping member 1 and the second clamping member 2.

[0046] Specifically, when the display screen bracket is in use, the first clamping member 1 and the second clamping member 2 can be placed on the front and rear sides of the display screen respectively. By adjusting the relative distance between the first clamping member 1 and the second clamping member 2 along the front and rear direction of the display screen, the first clamping member 1 and the second clamping member 2 can be brought closer to each other to clamp the display screen, or moved away from each other to release the display screen. In the embodiment of the utility model, the active member 3 is connected to at least one of the first clamping member 1 and the second clamping member 2. For example, when the active member 3 is only connected to one of the first clamping member 1 and the second clamping member 2, the other of the first clamping member 1 and the second clamping member 2 can be directly fixed on the display screen. In addition, the active member 3 can also be connected to the first clamping member 1 and the second clamping member 2 at the same time, as long as the active member 3 is connected to at least the first clamping member 1 or the second clamping member 2. In some embodiments, the active member 3 can directly adjust the distance between the first clamping member 1 and the second clamping member 2. When using the display screen bracket, the user can apply force to the active member 3 to make it move, and drive the first clamping member 1 and the second clamping member 2 to move relatively closer or farther through the active member 3. Specifically, the movement amplitude of the active member 3 can be controlled according to the size and shape of the display screen, so as to adjust the distance between the first clamping member 1 and the second clamping member 2 to different degrees to adapt to display screens of different thicknesses.

[0047] Specifically, the utility model embodiment also adopts a driven member 4 connected to at least one of the first clamping member 1 and the second clamping member 2, and the driven member 4 forms a transmission connection with the active member 3. When the active member 3 moves, the driven member 4 moves synchronously, thereby driving the first clamping member 1 and the second clamping member 2 to move, so as to clamp or release the display screen. Optionally, the specific form of the driven member 4 can be the same or different from the active member 3, and the driven member 4 can also be connected to the same or different clamping member as the active member 3, as long as it is reasonably designed so that the driven member 4 can adjust the distance between the first clamping member 1 and the second clamping member 2 under the drive of the active member 3. In some embodiments, the active member 3 can directly adjust the distance between the first clamping member 1 and the second clamping member 2, and at the same time, the active member 3 drives the driven member 4 to move. When designed in this way, the active member 3 and the driven member 4 can jointly adjust the distance between the first clamping member 1 and the second clamping member 2, and the consistency of adjustment is good. Of course, it is understandable that the active member 3 may not directly adjust the distance between the first clamping member 1 and the second clamping member 2, but may drive the driven member 4 to adjust the distance.

[0048] Optionally, the driven member 4 may be provided with one or more, and when provided with multiple, there are multiple arrangements. For example, in some embodiments, Figure 2 As shown, the first clamping member 1 and the second clamping member 2 are clamped together at a corner of the display screen, and the follower 4 is respectively provided along the length and width direction of the display screen, and is generally arranged in an L shape. In addition, in some embodiments, such as Figure 3 As shown, the driven member 4 can also be arranged on both sides of the active member 3 along the same direction; in some embodiments, such as Figure 4 As shown, the driven member 4 may also be provided with a plurality of parts in two directions; in some embodiments, as Figure 5 As shown, the follower 4 can also be arranged only on one side of the active member 3. It is understandable that the follower 4 can also be arranged in other reasonable ways, and can be designed according to factors such as the shape, size and position of the first clamping member 1 and the second clamping member 2 on the display screen, so that the follower 4 is distributed at different positions on the first clamping member 1 and the second clamping member 2. Through such a design, when adjusting, each follower 4 can apply force to different positions on the first clamping member 1 and the second clamping member 2, so that the first clamping member 1 and the second clamping member 2 are evenly stressed and move smoothly when adjusting the relative distance, and can provide a greater clamping force when clamping the display screen.

[0049] The display screen support provided by the embodiment of the utility model comprises a first clamping member 1, a second clamping member 2, an active member 3 and a driven member 4. By adopting that both the active member 3 and the driven member 4 are connected to at least one of the first clamping member 1 and the second clamping member 2, when the active member 3 can directly adjust the distance between the first clamping member 1 and the second clamping member 2, the driven member 4 and the active member 3 can respectively apply forces to multiple positions of the first clamping member 1 and the second clamping member 2; or, when multiple driven members 4 are provided, the multiple driven members 4 can respectively apply forces to multiple positions of the first clamping member 1 and the second clamping member 2, so that multiple positions can be adjusted synchronously, the clamping force and clamping stability of the first clamping member 1 and the second clamping member 2 are increased, and the display screen can be clamped more stably and reliably. Furthermore, by connecting the follower 4 with the active member 3, when using the display stand, the user only needs to adjust the active member 3 to drive the follower 4 to move, thereby driving the first clamping member 1 and the second clamping member 2 to move, thereby completing the adjustment operation of the stand without the need to adjust each component individually, thereby simplifying the use operation of the display stand and improving the user experience.

[0050] In some embodiments, Figure 6 and Figure 7 As shown, the first clamping member 1 includes a first clamping arm 1A and a second clamping arm 1B connected to each other, and the second clamping member 2 includes a third clamping arm 2A and a fourth clamping arm 2B connected to each other. The first clamping arm 1A and the third clamping arm 2A are arranged opposite to each other, and the second clamping arm 1B and the fourth clamping arm 2B are arranged opposite to each other. Through such an arrangement, two pairs of clamping arms are formed between the first clamping member 1 and the second clamping member 2, that is, the first clamping arm 1A and the third clamping arm 2A are one pair of clamping arms, and the second clamping arm 1B and the fourth clamping arm 2B are another pair of clamping arms. The two pairs of clamping arms can jointly provide a clamping force, so that the display screen can be reliably clamped. As for the angle between the two pairs of clamping arms, optionally, in some embodiments, as Figure 6 As shown, the angle between the two pairs of clamping arms can be 90°, so that the display screen bracket is in an "L" shape. The bracket of this shape can usually be clamped at a corner of the display screen; in other embodiments, such as Figure 7 As shown, the angle between the two pairs of clamping arms can be 180°, so that the display screen bracket is in a "I" shape, and the bracket of this shape can usually be clamped in the middle position of the edge of the display screen. Of course, it is understandable that the angle between the two pairs of clamping arms can also be other angles, as long as the display screen can be clamped and fixed.

[0051] Optionally, regarding the arrangement of the active member 3 and the driven member 4, in some embodiments, the active member 3 is connected to at least one of the first clamp arm 1A and the third clamp arm 2A to adjust the distance between the first clamp arm 1A and the third clamp arm 2A. The driven member 4 is connected to at least one of the second clamp arm 1B and the fourth clamp arm 2B to adjust the distance between the second clamp arm 1B and the fourth clamp arm 2B synchronously with the active member 3. When arranged in this way, the active member 3 and the driven member 4 are respectively used to adjust the distance between the two pairs of clamp arms. At the same time, the active member 3 drives the driven member 4 to move, thereby achieving synchronous adjustment of the distance between the two pairs of clamp arms, so that the two pairs of clamp arms are clamped or released at the same time, and the consistency of the activities is better.

[0052] In other embodiments, Figure 6 and Figure 7 As shown, the follower 4 includes a first follower 4A and a second follower 4B, and at least one of the first follower 4A and the second follower 4B is connected to the active member 3. For example, the first follower 4A and the second follower 4B can be connected to the active member 3 respectively, or the first follower 4A can be connected to the active member 3 and the second follower 4B can be connected to the first follower 4A, as long as the first follower 4A and the second follower 4B can move synchronously. The first follower 4A is connected to at least one of the first clamp arm 1A and the third clamp arm 2A to adjust the distance between the first clamp arm 1A and the third clamp arm 2A. The second follower 4B is connected to at least one of the second clamp arm 1B and the fourth clamp arm 2B to adjust the distance between the second clamp arm 1B and the fourth clamp arm 2B. The active member 3 is connected to at least one of the first clamping arm 1A, the second clamping arm 1B, the third clamping arm 2A and the fourth clamping arm 2B, and only needs to be connected to at least the first clamping member 1 or the second clamping member 2 to provide support for the installation position of the active member 3. In this way, the active member 3 can only be used to drive the follower 4 to move, and does not directly participate in the adjustment of the distance between the clamping arms. When this setting is adopted, the first follower 4A and the second follower 4B are respectively used to adjust the distance between the two pairs of clamping arms. The active member 3 drives the first follower 4A and the second follower 4B to move synchronously. This method can also achieve synchronous adjustment of the distance between the two pairs of clamping arms.

[0053] It is understandable that the two configurations of the active member 3 and the driven member 4 can be flexibly selected according to needs, as long as the distance between the two pairs of clamping arms can be adjusted synchronously.

[0054] In some embodiments, Figure 6 and Figure 7As shown, the first clamp arm 1A is rotationally connected to the second clamp arm 1B, and the third clamp arm 2A is rotationally connected to the fourth clamp arm 2B. For example, in one embodiment, the first clamp arm 1A and the second clamp arm 1B, and the third clamp arm 2A and the fourth clamp arm 2B can be rotationally connected through the same rotating shaft, and damping washers and other components can be provided as needed to increase the smoothness of the rotation so that the state of the clamp arm after rotation adjustment can remain stable. With such a design, the angles between the first clamp arm 1A and the second clamp arm 1B, and between the third clamp arm 2A and the fourth clamp arm 2B can be flexibly adjusted, so that the use state of the display screen bracket can be switched according to different usage scenarios and needs. For example, in the following example, Figure 6 and Figure 7 Switching between the two states shown effectively improves the flexibility of the display stand adjustment and its adaptability in different scenarios.

[0055] Optionally, for the adjustment range of the angle between the first clamp arm 1A and the second clamp arm 1B, and between the third clamp arm 2A and the fourth clamp arm 2B, in one embodiment, the adjustment range of the angle between the first clamp arm 1A and the second clamp arm 1B is 90° to 180°, and the adjustment range of the angle between the third clamp arm 2A and the fourth clamp arm 2B is 90° to 180°. This design can at least meet the requirements of the display bracket in the following embodiments: Figure 6 and Figure 7 Of course, it is understandable that the above-mentioned angle adjustment range can be set to other ranges, and the embodiments of the utility model do not make further limitations. In some embodiments, in order to limit the range of angle adjustment, a stop block, a spring or other structure for limiting position can be set at the position corresponding to the maximum angle and the minimum angle to prevent the angle between the clamping arms from exceeding the preset range.

[0056] In some embodiments, Figure 2 As shown, both the active member 3 and the driven member 4 include a connecting rod 51, one end of the connecting rod 51 is connected to at least one of the first clamping member 1 and the second clamping member 2 through a threaded structure, and the other end of the connecting rod 51 is provided with a rotating wheel 52. In other words, the active member 3 and the driven member 4 can be of the same type of structure, which includes the connecting rod 51 and the rotating wheel 52. Among them, the rotating wheel 52A of the active member 3 is connected to the rotating wheel 52B of the driven member 4, so that the rotating wheel 52A of the active member 3 can drive the rotating wheel 52B of the driven member 4 to rotate synchronously.

[0057] Optionally, the connecting rod 51 can be connected to only one of the first clamping member 1 and the second clamping member 2, and the other of the first clamping member 1 and the second clamping member 2 can be directly fixed on the display screen; the connecting rod 51 can also be connected to the first clamping member 1 and the second clamping member 2 at the same time. Among them, optionally, the connecting rod 51A of the active member 3 and the connecting rod 51B of the driven member 4 can be connected to the same clamping member, thereby driving the same clamping member to move; the connecting rod 51A of the active member 3 and the connecting rod 51B of the driven member 4 can also be connected to different clamping members respectively, thereby driving different clamping members to move respectively, as long as the active member 3 and the driven member 4 can be adjusted synchronously. Optionally, in order to realize the threaded connection between the connecting rod 51 and the clamping member, an external thread can be set on the connecting rod 51, and a corresponding threaded hole can be opened on the clamping member, or a threaded hole can be opened on the connecting rod 51, and an external thread can be set on the clamping member.

[0058] Optionally, the rotating wheel 52 can be rotatably connected to the first clamping member 1 and / or the second clamping member 2, or can be separately arranged from the first clamping member 1 and the second clamping member 2, which is not limited here, as long as the driving wheel 31 can be rotated and drive the connecting rod 51 to rotate. Optionally, the rotating wheel 52 of the driving member 3 and the rotating wheel 52 of the driven member 4 can be set as a gear, a pulley or a sprocket and other wheel-shaped structures that can be transmitted. When set as a gear, the rotating wheel 52 of the driving member 3 and the rotating wheel 52 of the driven member 4 can be directly meshed or indirectly meshed through an intermediate transmission gear, as long as the rotating wheel 52 of the driving member 3 and the rotating wheel 52 of the driven member 4 can be synchronously rotated.

[0059] By adopting the above design, when the rotating wheel 52 of the active member 3 rotates, the driven member 4 can be driven to rotate synchronously, and the connecting rod 51 of the active member 3 and the connecting rod 51 of the driven member 4 can be driven to rotate synchronously. When the connecting rod 51 rotates, the connecting rod 51 and the threaded structure on the clamping member rotate relative to each other, and drive the connecting rod 51 and the clamping member to move closer to or away from each other. This design can better achieve the adjustment of the relative distance. At the same time, by setting the active member 3 and the driven member 4 to the same type of adjustment structure 92, the types of components can be reduced, the complexity of the components can be simplified, and the consistency of the adjustment can be better.

[0060] In some embodiments, Figure 8As shown, the active member 3 includes a driving wheel 31 and a first adjusting rod 32. The driving wheel 31 is located on the side of the first clamping member 1 away from the second clamping member 2, and is connected to the driven member 4. One end of the first adjusting rod 32 is connected to the driving wheel 31, and the other end of the first adjusting rod 32 is provided with a first thread 33, and passes through the first clamping member 1 to connect with the second clamping member 2. Among them, the first clamping member 1 is provided with at least a first connecting hole 11 for the first adjusting rod 32 to pass through, and the second clamping member 2 is correspondingly provided with a second thread 21 for connecting with the first thread 33.

[0061] Specifically, the end of the first adjusting rod 32 away from the driving wheel 31 passes through the first connecting hole 11 provided on the first clamping member 1, and is connected to the second clamping member 2 through the first thread 33 and the second thread 21 that cooperate with each other. When the driving wheel 31 rotates, the first adjusting rod 32 rotates synchronously, and the first thread 33 and the second thread 21 rotate relatively, so that the first adjusting rod 32 and the second clamping member 2 are close to or away from each other. At the same time, the driving wheel 31 also drives the driven member 4 to move synchronously, so that the driving member 3 and the driven member 4 can be adjusted synchronously.

[0062] It should be noted that the first thread 33 and the second thread 21 are mutually compatible thread structures. Specifically, the first thread 33 can be set as an external thread and the second thread 21 can be set as an internal thread, or the first thread 33 can be set as an internal thread and the second thread 21 can be set as an external thread, as long as they can adapt to each other.

[0063] Optionally, there is no further limitation on the connection relationship between the driving wheel 31 and the first clamping member 1. The driving wheel 31 can be rotatably connected to the first clamping member 1 or can be separated from the first clamping member 1. When the driving wheel 31 is separated from the first clamping member 1, the first clamping member 1 can be directly fixed on the display screen as long as the driving wheel 31 can rotate relative to the first clamping member 1.

[0064] In the above design, the first adjusting rod 32 passes through the first connecting hole 11 and is threadedly connected to the second clamping member 2. The first connecting hole 11 can provide better guiding and limiting effects for the first adjusting rod 32, so that the connection position of the first adjusting rod 32 and the second clamping member 2 is accurate, and it is not easy to shake during rotation adjustment, thereby improving the stability of the rotation adjustment of the first adjusting rod 32.

[0065] In some embodiments, Figure 8As shown, a connecting portion 22 is provided on the second clamping member 2 extending toward the first clamping member 1, and a second thread 21 is provided on the connecting portion 22. Optionally, the connecting portion 22 can be a threaded connection structure such as a nut, a threaded column, a screw, etc. fixed on the second clamping member 2, wherein the thread is the second thread 21; the connecting portion 22 can also be a columnar structure integrally formed with the second clamping member 2, and the second thread 21 is processed after forming, as long as the second thread 21 can be formed on the connecting portion 22. In the above design, the connecting portion 22 is provided on the second clamping member 2 extending toward the first clamping member 1, and the connecting portion 22 can shorten the distance between the second clamping member 2 and the first clamping member 1, so that the first adjustment rod 32 is more easily connected to the second clamping member 2, and the connecting portion 22 has a certain size, which can provide a larger adjustment space, support a larger adjustment, and increase the flexibility of adjustment.

[0066] In some embodiments, Figure 8 As shown, the end of the connecting portion 22 facing the first clamping member 1 is inserted into the first connecting hole 11. This design can save the space occupied by the connecting portion 22 and make the bracket structure more compact. Fig. 9 As shown, a stopper 13 is provided at the position where the first connection hole 11 is provided on the first clamping member 1, and the stopper 13 abuts against the connection portion 22 to limit the relative rotation of the connection portion 22 and the first connection hole 11. Specifically, the stopper 13 abuts against the connection portion 22 along the circumference of the first connection hole 11, and a force-bearing surface facing the circumference of the first connection hole 11 is correspondingly provided on the connection portion 22, and the connection portion 22 abuts against the stopper 13 through the force-bearing surface to be subjected to the force of the stopper 13. For example, Fig. 9 As shown, the connecting portion 22 can be set in a semi-cylindrical shape, and the cross-section position of the semi-cylindrical portion and the stop block 13 are subjected to force, thereby limiting the rotation of the connecting portion 22. In this way, when the connecting portion 22 and the first adjusting rod 32 are adjusted through the threaded structure, no obvious rotation occurs, further improving the stability of the adjustment.

[0067] In some embodiments, Figure 8 As shown, the driven member 4 includes a driven wheel 41 and a second adjusting rod 42. The driven wheel 41 is located on the side of the first clamping member 1 away from the second clamping member 2, and is connected to the active member 3. The driven wheel 41 can be specifically connected to the active wheel 31. One end of the second adjusting rod 42 is connected to the second clamping member 2, and the other end of the second adjusting rod 42 is provided with a third thread 43, which passes through the first clamping member 1 and is connected to the driven wheel 41. Among them, the first clamping member 1 is provided with a second connecting hole 12 for the second adjusting rod 42 to pass through, and the driven wheel 41 is correspondingly provided with a fourth thread 44 for connecting with the third thread 43.

[0068] Specifically, the end of the second adjusting rod 42 away from the second clamping member 2 passes through the second connecting hole 12 provided on the first clamping member 1, and is connected to the driven wheel 41 through the third thread 43 and the fourth thread 44 that cooperate with each other. The driven wheel 41 can rotate synchronously under the drive of the driving wheel 31. When the driven wheel 41 rotates, the third thread 43 and the fourth thread 44 rotate relatively, so that the second adjusting rod 42 and the driven wheel 41 are moved closer to or farther from each other, and then the second clamping member 2 is driven to move through the second adjusting rod 42.

[0069] It should be noted that the third thread 43 and the fourth thread 44 are mutually compatible thread structures. Specifically, the third thread 43 can be set as an external thread and the fourth thread 44 can be set as an internal thread, or the third thread 43 can be set as an internal thread and the fourth thread 44 can be set as an external thread, as long as they can adapt to each other.

[0070] Optionally, there is no further limitation on the connection relationship between the driven wheel 41 and the first clamping member 1. The driven wheel 41 can be rotatably connected to the first clamping member 1 or can be separated from the first clamping member 1. When the driven wheel 41 is separated from the first clamping member 1, the first clamping member 1 can be directly fixed on the display screen as long as the driven wheel 41 can rotate relative to the first clamping member 1.

[0071] In the above design, the second adjusting rod 42 passes through the second connecting hole 12 and is threadedly connected to the follower 4. The second connecting hole 12 can provide better guiding and limiting effects for the second adjusting rod 42, so that the connection position of the second adjusting rod 42 and the follower 4 is accurate, and it is not easy to shake during rotation adjustment, thereby improving the stability of the rotation adjustment of the second adjusting rod 42.

[0072] It should be noted that the specific implementations of the active member 3 and the driven member 4 are interchangeable. Figure 8 As shown, in some embodiments, one end of the first adjustment rod 32 is connected to the driving wheel 31, and the other end is threadedly connected to the second clamping member 2. In other embodiments, one end of the second adjustment rod 42 is connected to the second clamping member 2, and the other end is threadedly connected to the driven wheel 41. However, it can be understood that the above embodiments can be interchangeable, that is, the first adjustment rod 32 can be configured to be connected to the second clamping member 2 at one end and threadedly connected to the driving wheel 31 at the other end, and the second adjustment rod 42 can be configured to be connected to the driven wheel 41 at one end and threadedly connected to the second clamping member 2 at the other end. Therefore, the design flexibility of the active member 3 and the driven member 4 is high, which is conducive to the differentiated design of the display bracket product.

[0073] In some embodiments, Figure 8As shown, the display screen bracket also includes a transmission member 6, which is connected to the driving wheel 31 and the driven wheel 41, and the transmission member 6 is used to drive the driven wheel 41 to rotate synchronously under the drive of the driving wheel 31. Specifically, the transmission member 6 can be designed according to the types of the driving wheel 31 and the driven wheel 41. For example, when the driving wheel 31 and the driven wheel 41 are set as pulleys, the transmission member 6 can be a synchronous belt; when the driving wheel 31 and the driven wheel 41 are set as gears, the transmission member 6 can be an intermediate gear meshed with the driving wheel 31 and the driven wheel 41 at the same time; when the driving wheel 31 and the driven wheel 41 are set as sprockets, the transmission member 6 can be a chain, and so on. In the above design, by adopting the transmission member 6, the transmission connection between the driving wheel 31 and the driven wheel 41 can be realized, and the size and type of the transmission member 6 can also be designed according to different needs to adjust the distance between the driving wheel 31 and the driven wheel 41, the transmission ratio and other parameters, and the design flexibility is high.

[0074] In some embodiments, Figure 1 and Figure 6 As shown, the display bracket also includes a fixing member 71 for fitting and fixing the display. The fixing member 71 can be directly connected to the side of the first clamping member 1 and / or the second clamping member 2 facing the display, specifically, it can be directly connected by providing a single-sided adhesive on the fixing member 71 for bonding; the fixing member 71 can also be rotatably connected to the side of the first clamping member 1 and / or the second clamping member 2 facing the display through a rotating shaft 72.

[0075] Specifically, the fixing member 71 can be a component that can be attached to the display screen, such as Velcro, adhesive tape, etc. When the fixing member 71 is Velcro with a hard fur surface, Velcro with a soft fur surface can be pasted on the corresponding position on the display screen; when the fixing member 71 is Velcro with a soft fur surface, Velcro with a hard fur surface can be pasted on the display screen. Among them, the Velcro pasted on the display screen can be significantly larger in area than the fixing member 71, so that the fixing member 71 can be attached to different positions of the display screen, which is convenient for adjusting and replacing the fixed position. Optionally, the fixing member 71 can be set only on the first clamping member 1 or the second clamping member 2, or it can be set on the first clamping member 1 and the second clamping member 2 at the same time. One or more fixing members 71 can be set on the same clamping member, and the configuration is flexible and can be designed according to actual needs.

[0076] By adopting the above design, the fixing member 71 can fix the clamping member and the display screen, and even when the clamping force is insufficient, the clamping member is not easy to loosen, further improving the stability of the bracket and the display screen. When the fixing member 71 is rotatably connected to the clamping member through the rotating shaft 72, the fixing member 71 can also be rotated to adjust the angle, which is conducive to better fitting and fixing the display screen, and is particularly suitable for some display screens with curved shapes.

[0077] In some embodiments, Figure 8 As shown, a buffer pad 73 is provided on one side of the first clamping member 1 and / or the second clamping member 2 for the display screen, and the buffer pad 73 abuts against the display screen. Specifically, the buffer pad 73 is usually made of a flexible material such as rubber, and directly contacts the display screen through the buffer pad 73, thereby providing a buffer protection for the display screen. Optionally, the buffer pad 73 can be provided only on the first clamping member 1 or the second clamping member 2, or can be provided on the first clamping member 1 and the second clamping member 2 at the same time, and one or more buffer pads 73 can be provided on the same clamping member. In the above design, by using the buffer pad 73 to abut against the display screen, an effective protection effect can be provided for the display screen, and the display screen bracket can be better prevented from scratching the display screen when clamping the display screen. At the same time, the buffer pad 73 can also fully fill the gap between the clamping member and the display screen, ensure full contact, increase the area of ​​action of the clamping force, and have an anti-slip effect to a certain extent.

[0078] In some embodiments, Figure 8 As shown, the first clamping member 1 is provided with a receiving cavity 14 for receiving at least part of the active member 3 and the driven member 4, and the display screen bracket further comprises a cover plate 81, which is disposed on the first clamping member 1 and closes the receiving cavity 14. Specifically, in some design schemes, the receiving cavity 14 can accommodate the active wheel 31 and the driven wheel 41, and can also accommodate components such as the transmission member 6, and the use of the cover plate 81 to close the receiving cavity 14 can provide good protection, better avoid interference of the external environment on the active wheel 31, the driven wheel 41 and the transmission member 6, etc., ensure smooth and stable adjustment of the display screen bracket, and improve the aesthetics.

[0079] In some embodiments, Figure 8 As shown, the display screen bracket also includes a knob 82, which is connected to the active member 3 to drive the active member 3 to rotate. Specifically, the knob 82 is a structure for the user to apply force to turn. To facilitate the user to apply force, a knurling structure or the like can be provided on the outer side of the knob 82 to increase the roughness of the knob 82. The knob 82 can also be made of a material with a relatively large roughness. In some design schemes, such as Figure 1 and Figure 6 As shown, the knob 82 can pass through the cover plate 81 to be connected to the driving wheel 31, and the knob 82 is exposed outside the accommodating cavity 14, while the driving wheel 31 is arranged in the accommodating cavity 14. With this design, the driving wheel 31 is not easily damaged, has better reliability, and has a good structural aesthetics.

[0080] In some embodiments, Figure 1 and Figure 6As shown, the display screen bracket also includes an adjustment bracket 91 for connecting a mobile terminal, and the adjustment bracket 91 is connected to the first clamping member 1 or the second clamping member 2 through an adjustment structure 92. Specifically, the adjustment bracket 91 is generally used to install mobile devices such as mobile phones. When the display screen bracket is fixed on the display screen through the first clamping member 1 and the second clamping member 2, the user can fix the mobile phone on the adjustment bracket 91 to operate the display screen of the mobile phone and the multimedia device at the same time. Specifically, as Figure 8 As shown, taking the example of the adjustment bracket 91 connected to the second clamping member 2 through the adjustment structure 92, the adjustment structure 92 may include an adjustment hole 921 provided on the adjustment bracket 91 and a corresponding protrusion (not shown in the figure) provided on the second clamping member 2, at least two protrusions are provided, and more than three adjustment holes 921 are provided, and any two adjustment holes 921 can be matched with two protrusions to achieve positioning. Optionally, each adjustment hole 921 can be evenly distributed around the same circumference. In this way, the adjustment bracket 91 can be adjusted relative to the second clamping member 2 by matching the adjustment holes 921 at different positions with the protrusions.

[0081] The above design connects the adjustment bracket 91 to the first clamping member 1 or the second clamping member 2 by using the adjustment structure 92, so that the adjustment bracket 91 can adjust the use angle relative to the clamping member. The configuration is flexible and can meet different use angle requirements.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
