Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a bracket. Background Technology

[0002] Users typically mount display devices on stands for ease of use. Sometimes, it's necessary to adjust the angle of the display device during use. In existing technology, the stand maintains the angle of the display device through friction; when the user applies a sufficiently large external force, the angle can be changed. When the display device is heavy, the frictional force cannot balance its weight, causing the angle to become unstable. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a stand that can maintain and adjust the angle of a heavy display device.

[0004] This utility model provides a bracket, which includes a support mechanism, a connecting mechanism, and an adjusting mechanism. The support mechanism is used to connect to a support surface; the connecting mechanism is used to connect to a display device, and the connecting mechanism is rotatably connected to the support mechanism, allowing the connecting mechanism to rotate relative to the support mechanism around a first axis; the adjusting mechanism includes a limiting component and an adjusting component, one of which is connected to the support mechanism and the other to the connecting mechanism. The limiting component has multiple limiting grooves, which are arranged circumferentially along the first axis. The adjusting component can enter and exit the limiting grooves. When the adjusting component enters a limiting groove, the relative rotation between the adjusting component and the limiting component is restricted. When the adjusting component enters different limiting grooves, the circumferential angle between the adjusting component and the limiting component centered on the first axis is different. When the adjusting component exits a limiting groove, the adjusting component and the limiting component can rotate relative to each other.

[0005] The bracket provided by this embodiment of the utility model has at least the following beneficial effects:

[0006] When the adjustment component enters the limiting slot, the relative rotation between the adjustment component and the limiting component is restricted. When the adjustment component exits the limiting slot, the relative rotation between the adjustment component and the limiting component is allowed. On the one hand, when the adjustment component exits the limiting slot, the angle of the display device on the bracket can be changed. On the other hand, when the display device is heavy and the adjustment component enters the limiting slot, the bracket can fix the display device. Moreover, when the adjustment component enters different limiting slots, the bracket fixes the display device at different angles, thereby enabling the maintenance and adjustment of the angle of a heavy display device.

[0007] In one embodiment of this implementation, the bracket further includes a rotating shaft mounted on the support mechanism. The limiting component is circumferentially rotatable relative to the first axis and axially fixed relative to the rotating shaft. The limiting component is connected to the connecting mechanism, and the adjusting component is slidably connected to the rotating shaft relative to the first axis.

[0008] In one embodiment of this implementation, the adjusting component includes an adjusting seat and an adjusting pin. The adjusting pin is connected to the adjusting seat, and the adjusting seat is slidably connected to the rotating shaft along the first axial direction. When the adjusting seat moves, the adjusting pin can move in and out of the limiting groove along the first axial direction.

[0009] In one embodiment of this implementation, the adjusting assembly further includes a first elastic element, the adjusting pin and the adjusting seat are slidably connected along the first axis direction, the first elastic element is mounted on the adjusting seat, and the first elastic element provides a force to the adjusting pin along the first axis direction and toward the limiting groove.

[0010] In one embodiment of this implementation, there are two adjusting pins, which are symmetrically distributed around the first axis. The plurality of limiting grooves are divided into multiple groups of two, with the two limiting grooves in each group being symmetrically distributed around the first axis.

[0011] In one embodiment of this implementation, the adjustment assembly further includes an end cap and a connecting rod. The end cap is for user pressing. One end of the connecting rod is connected to the end cap, and the other end is connected to the adjustment seat. The connecting rod and the rotating shaft can slide along the first axis direction. The limiting assembly is located between the end cap and the adjustment seat. When the end cap approaches the limiting assembly along the first axis direction, the adjustment seat moves away from the limiting assembly along the first axis direction, and drives the adjustment pin away from the limiting groove.

[0012] In one embodiment of this implementation, the limiting component has a plurality of limiting holes, which are arranged circumferentially along the first axis and correspond one-to-one with a plurality of limiting grooves. The axis of the limiting hole is parallel to the first axis. The adjusting component also includes a limiting shaft, which is connected to the adjusting pin. When the adjusting pin enters the limiting groove, the limiting shaft enters the corresponding limiting hole.

[0013] In one embodiment of this implementation, a limiting guide structure is provided on the wall of the limiting hole, and the limiting guide structure can provide guidance for the limiting shaft as it enters the limiting hole.

[0014] In one embodiment of this implementation, the support mechanism is provided with a guide groove, the extension direction of the guide groove is parallel to the first axis, the adjustment component is provided with a guide pin, the guide pin and the guide groove can be slidably engaged along the first axis, and the guide groove can restrict the rotation of the adjustment component relative to the support mechanism.

[0015] In one embodiment of this implementation, a second elastic element is provided on the support mechanism. The second elastic element is connected to the adjustment component. The second elastic element can provide a force parallel to the first axis direction to the adjustment component, so that the adjustment component moves in the direction of entering the limiting groove.

[0031] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0032] This utility model provides a bracket 100, please refer to... Figures 1 to 4 , Figure 1 This is a three-dimensional structural schematic diagram of the support 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 A partial structural diagram of the support mechanism 10, the connecting mechanism 20, and the adjusting mechanism 30; Figure 3 yes Figure 1 Disassembly diagram of bracket 100; Figure 4 yes Figure 3 A schematic diagram of the adjustment mechanism 30 and the rotating shaft 40. The bracket 100 includes a support mechanism 10, a connecting mechanism 20 and an adjustment mechanism 30. The support mechanism 10 is used to connect with the support surface; the connecting mechanism 20 is used to connect with the display device, and the connecting mechanism 20 is rotatably connected to the support mechanism 10. The connecting mechanism 20 can rotate relative to the support mechanism 10 around the first axis; the adjustment mechanism 30 includes a limiting component 31 and an adjustment component 32. One of the limiting component 31 and the adjustment component 32 is connected to the support mechanism 10, and the other is connected to the connecting mechanism 20. The limiting component 31 has multiple limiting grooves 311, which are arranged circumferentially along the first axis. The adjustment component 32 can enter and exit the limiting grooves 311. When the adjustment component 32 enters the limiting groove 311, the relative rotation between the adjustment component 32 and the limiting component 31 is restricted. When the adjustment component 32 enters different limiting grooves 311, the circumferential angle between the adjustment component 32 and the limiting component 31 centered on the first axis is different. When the adjustment component 32 exits the limiting groove 311, the adjustment component 32 and the limiting component 31 can rotate relative to each other.

[0033] Please refer to the following for details. Figure 5 and Figure 6 , Figure 5 yes Figure 4 A disassembly diagram of the adjustment mechanism 30 and the rotating shaft 40; Figure 6 yes Figure 5A schematic diagram of the structure of the limiting component 31 is provided. The limiting component 31 is connected to the connecting mechanism 20, and the adjusting component 32 is connected to the supporting mechanism 10. The limiting component 31 is cylindrical, and its axis is the first axis. A limiting groove 311 is formed on the outer peripheral surface of the limiting component 31. A portion of the outer peripheral surface of the limiting component 31 is recessed along the direction close to the first axis to form the limiting groove 311. Multiple limiting grooves 311 are arranged along the outer peripheral surface of the limiting component 31. The adjusting component 32 is rotatably engaged with the limiting component 31. The bracket 100 also includes a torsion spring 50. One end of the torsion spring 50 is connected to the connecting mechanism 20, and the other end is connected to the supporting mechanism 10. The torsion spring 50 can provide a circumferential force along the first axis to the connecting mechanism 20. It should be understood that in some other embodiments, the adjusting component 32 is connected to the connecting mechanism 20, and the limiting component 31 is connected to the supporting mechanism 10.

[0034] Understandably, after the adjusting component 32 enters the limiting groove 311, the groove wall of the limiting groove 311 can abut against the adjusting component 32, thereby providing circumferential support force along the first axis to restrict the rotation of the adjusting component 32 relative to the limiting component 31, and thus restrict the rotation of the support mechanism 10 relative to the connecting mechanism 20. After the user applies external force to the adjusting component 32, the adjusting component 32 can exit the limiting groove 311, thereby allowing the adjusting component 32 to rotate relative to the limiting component 31. Adjacent limiting grooves 311 have corresponding circumferential angles centered on the first axis. The adjusting component 32 can change the relative circumferential angle between the adjusting component 32 and the limiting component 31 centered on the first axis by rotating relative to the limiting component 31 and entering different limiting grooves 311, thereby changing the relative angle between the support mechanism 10 and the connecting mechanism 20. The torsion spring 50 allows the user to more easily adjust the angle of the display device.

[0035] In this utility model, when the adjustment component 32 enters the limiting groove 311, the relative rotation between the adjustment component 32 and the limiting component 31 is restricted. When the adjustment component 32 exits the limiting groove 311, the relative rotation between the adjustment component 32 and the limiting component 31 is allowed. On the one hand, when the adjustment component 32 exits the limiting groove 311, the angle of the display device on the bracket 100 can be changed. On the other hand, when the display device is heavy and the adjustment component 32 enters the limiting groove 311, the bracket 100 can fix the display device. Moreover, when the adjustment component 32 enters different limiting grooves 311, the bracket 100 fixes the display device at different angles, thereby enabling the maintenance and adjustment of the angle of a heavy display device.

[0036] In one embodiment of this implementation, please refer to Figures 3 to 5The bracket 100 also includes a rotating shaft 40, which is mounted on the support mechanism 10. The limiting component 31 is rotatable relative to the rotating shaft 40 in the circumferential direction along the first axis and is axially fixed relative to the rotating shaft 40. The limiting component 31 is connected to the connecting mechanism 20, and the adjusting component 32 is slidably connected to the rotating shaft 40 in the direction of the first axis.

[0037] Please refer to the following for details. Figure 6 The axis of the rotating shaft 40 coincides with the first axis. The rotating shaft 40 is fixed on the support mechanism 10. The adjusting component 32 and the support mechanism 10 can slide together along the first axis. The limiting component 31 has a mounting hole 313. The axis of the mounting hole 313 coincides with the first axis. The rotating shaft 40 passes through the mounting hole 313. The circumferential surface of the rotating shaft 40 rotates with the wall of the mounting hole 313. The connecting mechanism 20 includes a first part 21 and a second part 22. The first part 21 is used to connect with the display device. The first part 21 and the second part 22 together form a cylindrical cavity. The limiting component 31 is disposed in the cylindrical cavity and is connected to the first part 21.

[0038] It is understood that the support mechanism 10 and the connecting mechanism 20 are relatively fixed along the first axis, and the limiting component 31 is connected to the connecting mechanism 20. The limiting component 31 is rotatably engaged with the rotating shaft 40 through the mounting hole 313, allowing the limiting component 31 and the rotating shaft 40 to rotate relative to each other circumferentially along the first axis while remaining relatively fixed axially. This allows the limiting component 31 to rotate relative to the adjusting component 32, facilitating the relative rotation of the support mechanism 10 and the connecting mechanism 20. The adjusting component 32 and the rotating shaft 40 are slidably connected relative to each other along the first axis, allowing the adjusting component 32 to move in and out of the limiting groove 311 along the first axis. By setting the first part 21 and the second part 22, the manufacturing difficulty of the connecting mechanism 20 can be reduced, and the assembly of the limiting component 31 can be facilitated.

[0039] In one embodiment of this implementation, please refer to Figures 4 to 5 The adjustment assembly 32 includes an adjustment seat 321 and an adjustment pin 322. The adjustment pin 322 is connected to the adjustment seat 321. The adjustment seat 321 and the rotating shaft 40 can be slidably connected along the first axis direction. When the adjustment seat 321 moves, the adjustment pin 322 can move in and out of the limiting groove 311 along the first axis direction.

[0040] Specifically, the adjusting pin 322 is detachably connected to the adjusting seat 321. Understandably, the fact that the adjusting seat 321 and the adjusting pin 322 are not integrally designed reduces the manufacturing difficulty of the adjusting component 32. The detachable connection between the adjusting seat 321 and the adjusting pin 322 allows the user to easily replace the adjusting pin 322 when it wears out.

[0041] In one embodiment of this implementation, please refer to Figure 4 and Figure 5 The adjustment assembly 32 also includes a first elastic element 324. The adjustment pin 322 and the adjustment seat 321 are slidably connected along the first axis direction. The first elastic element 324 is mounted on the adjustment seat 321. The first elastic element 324 provides a force to the adjustment pin 322 along the first axis direction and toward the limiting groove 311.

[0042] Specifically, the adjusting seat 321 has a groove 3211 whose shape and size are adapted to the adjusting pin 322. The first elastic element 324 and the adjusting pin 322 are both set in the groove 3211. The adjusting pin 322 slides in cooperation with the side wall of the groove 3211. One end of the first elastic element 324 abuts against the bottom wall of the groove 3211, and the other end abuts against the adjusting pin 322. The first elastic element 324 is a spring that extends along the first axis and can undergo elastic deformation along the first axis. A cover plate 328 is also provided on one side of the adjusting seat 321, which covers the groove 3211.

[0043] Understandably, the sidewall of the slide groove 3211 can guide the movement of the adjusting pin 322 along the first axis. Through the cooperation between the sidewall of the slide groove 3211 and the adjusting pin 322, the adjusting pin 322 and the adjusting seat 321 can be slidably connected along the first axis. The cover plate 328 can reduce the risk of the adjusting pin 322 disengaging from the slide groove 3211. During the rotation of the adjusting seat 321 relative to the limiting component 31, when the adjusting pin 322 is not yet aligned with the limiting groove 311, the adjusting pin 322 cannot enter the limiting groove 311. The spring can push the adjusting pin 322 so that the adjusting pin 322 abuts against the limiting component 31. When the adjusting seat 321 rotates until the adjusting pin 322 is aligned with the limiting groove 311, the adjusting pin 322 can enter the limiting groove 311 under the push of the spring. This setting can reduce the difficulty of the adjusting pin 322 entering the limiting groove 311, thereby improving the user experience.

[0044] In one embodiment of this implementation, please refer to Figure 5 and Figure 6 There are two adjusting pins 322, which are symmetrically distributed around the first axis. Multiple limiting grooves 311 are divided into multiple groups of two, with the two limiting grooves 311 in each group being symmetrically distributed around the first axis.

[0045] Specifically, there are ten limiting slots 311 in total, and the ten limiting slots 311 are divided into five groups of two. With this arrangement, the two adjusting pins 322 can simultaneously cooperate with two limiting slots 311 in one group of limiting slots 311, which helps to improve the load capacity of the adjusting component 32 and the limiting component 31.

[0046] In one embodiment of this implementation, please refer to Figure 5The adjustment assembly 32 also includes an end cap 325 and a connecting rod 326. The end cap 325 is used for user pressing. One end of the connecting rod 326 is connected to the end cap 325, and the other end is connected to the adjustment seat 321. The connecting rod 326 and the rotating shaft 40 can slide along the first axis direction. The limiting assembly 31 is located between the end cap 325 and the adjustment seat 321. When the end cap 325 approaches the limiting assembly 31 along the first axis direction, the adjustment seat 321 moves away from the limiting assembly 31 along the first axis direction, and drives the adjusting pin 322 to leave the limiting groove 311.

[0047] Specifically, the end cap 325 and the adjusting seat 321 are arranged at intervals along the first axis. The rotating shaft 40 is tubular and has a hollow portion 41. The rotating shaft 40 is located between the end cap 325 and the adjusting seat 321. The adjusting seat 321 is located at the end of the rotating shaft 40 opposite to the end cap 325. The axis of the connecting rod 326 coincides with the first axis. One end of the connecting rod 326 is connected to the end cap 325, and the other end extends along the first axis and passes through the hollow portion 41 to connect with the adjusting seat 321. The connecting rod 326, which passes through the hollow portion 41, and the rotating shaft 40 can slide together along the first axis. It can be understood that the limiting component 31 and the rotating shaft 40 are fixed relative to the supporting mechanism 10 and the connecting mechanism 20 in the direction of the first axis. When the user presses the end cap 325, the connecting rod 326 can push the adjusting seat 321 to move along the first axis, so that the adjusting seat 321 drives the adjusting pin 322 out of the limiting groove 311, which facilitates user use.

[0048] In one embodiment of this implementation, please refer to Figure 5 and Figure 6 The limiting component 31 has multiple limiting holes 312, which are arranged circumferentially along the first axis. Each limiting hole 312 corresponds to a limiting groove 311. The axis of the limiting hole 312 is parallel to the first axis. The adjusting component 32 also includes a limiting shaft 323, which is connected to the adjusting pin 322. When the adjusting pin 322 enters the limiting groove 311, the limiting shaft 323 enters the corresponding limiting hole 312.

[0049] Specifically, both the adjusting pin 322 and the limiting shaft 323 extend along the first axis. In the circumferential direction centered on the first axis, the circumferential angle of two adjacent limiting holes 312 is the same as the circumferential angle of the corresponding two adjacent limiting grooves 311. It can be understood that the limiting shaft 323 and the adjusting pin 322 can work together to restrict the rotation of the adjusting component 32 relative to the limiting component 31, which is beneficial to improving the load capacity of the bracket 100.

[0050] In one embodiment of this implementation, please refer to Figure 6A limiting guide structure 3121 is provided on the wall of the limiting hole 312. During the process of the limiting shaft 323 entering the limiting hole 312, the limiting guide structure 3121 provides guidance for the limiting shaft 323. Specifically, the limiting guide structure 3121 is chamfered. It can be understood that when the limiting shaft 323 enters the limiting hole 312, the adjusting pin 322 enters the corresponding limiting groove 311. The limiting guide mechanism makes it easier for the limiting shaft 323 to enter the limiting hole 312, thereby making it easier for the adjusting pin 322 to enter the limiting groove 311, which is beneficial to improving the user experience.

[0051] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 The support mechanism 10 has a guide groove 11 extending parallel to the first axis. The adjustment component 32 has a guide pin 327, which slidably engages with the guide groove 11 along the first axis. The guide groove 11 restricts the rotation of the adjustment component 32 relative to the support mechanism 10. Specifically, there are two guide grooves 11 and two guide pins 327, each corresponding to a different guide groove 11. The guide groove 11 provides a circumferential force to the guide pin 327 along the first axis, restricting its rotation relative to the support mechanism 10. The guide pin 327, located on the adjustment component 32, further restricts its rotation relative to the support mechanism 10, reducing the risk that the bracket 100 may lose its angle due to the rotation of the adjustment component 32 relative to the support mechanism 10.

[0052] In one embodiment of this implementation, please refer to Figure 4 and Figure 5 The support mechanism 10 is provided with a second elastic element 12, which is connected to the adjustment component 32. The second elastic element 12 can provide a force parallel to the first axis to the adjustment component 32, so that the adjustment component 32 moves in the direction of entering the limiting groove 311.

[0053] Specifically, the second elastic element 12 is a spring. It is understood that before the user adjusts the angle of the display device, the adjustment component 32 must first move away from the limiting groove 311. After the user completes the angle adjustment, the adjustment component 32 needs to move back along the first axis and enter the limiting groove 311 to maintain the angle of the display device. By setting the second elastic element 12, the adjustment component 32 can be automatically reset, improving the user experience.

[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
