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. These stands usually include a support mechanism and a connector that can be raised and lowered relative to the support mechanism. The connector allows the display device to be raised or lowered to suit the user's needs. However, in existing technology, if the connector lowers the display device too far, it may cause the display device to bump or knock, resulting in damage. 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 bracket capable of limiting the descent distance of a display device.

[0004] This utility model provides a bracket, which includes a support mechanism and a connecting mechanism. The support mechanism is used to mount on a support surface and has a limiting hole. The support mechanism has a first surface. The connecting mechanism includes a connector, a slider, and an elastic element. The connector is used to connect to a display device and is vertically and vertically connected to the support mechanism. The slider is connected to the connector through the elastic element and elastically abuts against the first surface. When the connector descends relative to the support mechanism to a preset position, the slider engages with the limiting hole to limit the connector from further descent.

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

[0006] The connector can be raised and lowered relative to the support mechanism. When the connector descends to a preset position relative to the support mechanism, the slider engages with the limiting hole to limit the connector from continuing to descend, thereby limiting the descent distance of the connector and, consequently, limiting the descent distance of the display device, which helps reduce the risk of damage to the display device.

[0007] In one embodiment of this implementation, the slider is provided with an inclined surface, and a portion of the wall of the limiting hole forms an inclined hole wall adapted to the inclined surface. When the connector rises relative to the support mechanism, the inclined hole wall abuts against the inclined surface and exerts a force on the inclined surface, so as to make the slider exit the limiting hole.

[0008] In one embodiment of this implementation, a pusher is provided in the limiting hole, the pusher can abut against the slider, and the pusher is used for the user to push the slider out of the limiting hole.

[0009] In one embodiment of this implementation, the connector has a fixing hole, and the slider is movably disposed in the fixing hole along the axial direction of the fixing hole. The slider can move relative to the fixing hole to enter and exit the limiting hole.

[0010] In one embodiment of this implementation, the slider has a strip groove extending along the axial direction of the fixing hole, the connector cooperates with the strip groove, and the strip groove is used to limit the distance the slider moves relative to the fixing hole.

[0011] In one embodiment of this implementation, the support mechanism has a chamber and an opening, the opening being connected to the chamber. The bracket also includes a rotating seat and a hook. The rotating seat is rotatably connected to the support mechanism, and the hook is disposed on the rotating seat. The hook is used to fix a cable. The rotating seat can drive the hook to rotate relative to the support mechanism, so that the hook enters and exits the chamber through the opening.

[0012] In one embodiment of this implementation, one of the rotating seat and the support mechanism is provided with a protrusion, and the other is provided with a slot. The protrusion can extend into or disengage from the slot as the rotating seat rotates, and the slot is used to fix the rotating seat relative to the support mechanism.

[0013] In one embodiment of this implementation, the rotating seat is provided with two sets of protrusions, which are respectively arranged on both sides of the rotating axis of the rotating seat. The two sets of protrusions are symmetrically distributed with the rotating axis of the rotating seat as the center. The support mechanism is provided with two sets of slots, which are respectively arranged on both sides of the rotating axis of the rotating seat. The two sets of slots are symmetrically distributed with the rotating axis of the rotating seat as the center. The interval between the two sets of protrusions is equal to the interval between the two sets of slots.

[0014] In one embodiment of this implementation, the support mechanism has a second surface, the rotating seat has a third surface, the second surface and the third surface are adapted to each other in shape, and when the rotating seat rotates to the point where the hook extends into the cavity, the second surface and the third surface are flush.

[0015] In one embodiment of this implementation, one end of the hook is connected to the rotating seat, and the other end extends along an arc path. The axis of the arc path coincides with the axis of the rotating seat, and the size of the opening is adapted to the diameter of the arc path.

[0034] 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.

[0035] Please see Figures 1 to 4 , Figure 6 and Figure 8 , 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 schematic diagram of the support mechanism 10 and the connecting mechanism 20; Figure 3 yes Figure 2 A partial structural schematic diagram of the support mechanism 10 and the connecting mechanism 20; Figure 4 yes Figure 3 An enlarged schematic diagram of some of the structures shown; Figure 6 yes Figure 2 A partial disassembly diagram of the support mechanism 10 and the connecting mechanism 20; Figure 8 yes Figure 6 The diagram shows an enlarged view of a portion of the structure. This embodiment of the invention provides a bracket 100, which includes a support mechanism 10 and a connecting mechanism 20. The support mechanism 10 is disposed on a support surface and has a limiting hole 11. The support mechanism 10 has a first surface 12. The connecting mechanism 20 includes a connector 21, a slider 22, and an elastic member 23. The connector 21 is used to connect to a display device and is vertically and vertically connected to the support mechanism 10. The slider 22 is connected to the connector 21 via the elastic member 23 and elastically abuts against the first surface 12. When the connector 21 descends relative to the support mechanism 10 to a preset position, the slider 22 engages with the limiting hole 11 to limit the connector 21 from further descent.

[0036] Specifically, the elastic element 23 is a spring, the support mechanism 10 includes a guide rail 15 and a support member 16, the guide rail 15 and the support member 16 are connected, the support member 16 is located on one side of the guide rail 15 along the horizontal direction, the support member 16 and the guide rail 15 both extend in the vertical direction, the connecting member 21 can slide with the guide rail 15 in the vertical direction, the limiting hole 11 is opened on the support member 16, the axis of the limiting hole 11 is parallel to the horizontal direction, the first surface 12 is formed on the support member 16, the first surface 12 is located on the side of the support member 16 opposite to the guide rail 15, the first surface 12 is a plane parallel to the vertical direction, the slider 22 and the connecting member 21 can slide relative to each other in the horizontal direction, and the elastic element 23 can provide a driving force to the slider 22 in the horizontal direction.

[0037] Understandably, the connector 21 can move vertically to achieve lifting and lowering relative to the support mechanism 10. The guide rail 15 guides the vertical movement of the connector 21. The elastic element 23 pushes the slider 22 horizontally until the slider 22 abuts against the first surface 12. The first surface 12 provides support force to the slider 22 to balance the driving force provided by the elastic element 23 to the slider 22. The first surface 12 extends vertically. During the vertical movement of the connector 21, the slider 22 moves vertically with the connector 21 and remains abutted against the first surface 12. When the connector 21 moves to the preset position, the slider 22 is opposite to the limiting hole 11, and the slider 22 does not abut against the first surface 12. Under the driving force provided by the elastic element 23, the slider 22 moves horizontally into the limiting hole 11. The wall of the limiting hole 11 provides a vertical force to the slider 22 to restrict the vertical movement of the connector 21, thereby limiting the connector 21 from continuing to descend relative to the support mechanism 10.

[0038] The bracket 100 of this utility model has a connector 21 that can be raised and lowered relative to the support mechanism 10. When the connector 21 descends to a preset position relative to the support mechanism 10, the slider 22 cooperates with the limiting hole 11 to limit the connector 21 from continuing to descend, thereby limiting the descent distance of the connector 21 and thus limiting the descent distance of the display device, which helps to reduce the risk of damage to the display device.

[0039] In one embodiment of this implementation, please refer to Figure 3 , Figure 4 and Figure 6 The slider 22 is provided with an inclined surface 221. Part of the hole wall of the limiting hole 11 forms an inclined hole wall 111 that is adapted to the inclined surface 221. When the connecting piece 21 rises relative to the support mechanism 10, the inclined hole wall 111 abuts against the inclined surface 221 and exerts a force on the inclined surface 221, so that the slider 22 exits the limiting hole 11.

[0040] For details, please refer to Figure 3 , Figure 3 The diagram shows the state of the slider 22 when it enters the limiting hole 11. The inclined surface 221 is set above the slider 22, and the inclined hole wall 111 is inclined in the vertical direction and connected to the first surface 12. When the slider 22 enters the limiting hole 11, the inclined hole wall 111 is located above the slider 22.

[0041] It is understood that when the connector 21 is in the preset position and the slider 22 enters the limiting hole 11, the user applies a force in the vertically upward direction to the connector 21. The inclined surface 221 can abut against the inclined hole wall 111, which provides guidance for the slider 22. The slider 22 moves along the inclined hole wall 111 to move away from the limiting hole 11 and re-abut against the first surface 12. With this configuration, when the connector 21 is in the preset position, the downward movement of the connector 21 relative to the support mechanism 10 is restricted, while the upward movement of the connector 21 relative to the support mechanism 10 is unrestricted, which is beneficial to improving the user experience. It should be understood that in some other embodiments, a rounded corner can be provided on the slider 22, and an arc-shaped surface adapted to the rounded corner can be provided on the hole wall of the limiting hole 11, so that when the connector 21 moves upward from the preset position, the slider 22 can be guided and exit the limiting hole 11.

[0042] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 and Figure 6 A pusher 24 is provided inside the limiting hole 11. The pusher 24 can abut against the slider 22. The pusher 24 is used for the user to push the slider 22 out of the limiting hole 11.

[0043] Specifically, the pusher 24 is movably connected to the support 16, and the pusher 24 can move horizontally relative to the support 16. When the pusher 24 moves, a portion of the pusher 24 can enter and exit the limiting hole 11. It can be understood that when the slider 22 enters the limiting hole 11, the user can use the pusher 24 to push the slider 22 out of the limiting hole 11, so that the connector 21, which is in a preset position, can continue to lower the display device, thus adapting to more usage environments.

[0044] In one embodiment of this implementation, please refer to Figure 6 and Figure 8 The connector 21 has a fixing hole 211. The slider 22 is movably disposed in the fixing hole 211 along the axial direction of the fixing hole 211. The slider 22 can move relative to the fixing hole 211 to enter and exit the limiting hole 11.

[0045] Specifically, the axis of the fixing hole 211 is parallel to the horizontal direction and perpendicular to the first surface 12. The slider 22 slides against the peripheral wall of the fixing hole 211. The elastic element 23 is disposed between the slider 22 and the bottom wall of the fixing hole 211. One end of the elastic element 23 is connected to the bottom wall of the fixing hole 211, and the other end is connected to the slider 22. It can be understood that since the axis of the fixing hole 211 is parallel to the horizontal direction, the peripheral wall of the fixing hole 211 can restrict the slider 22 from moving vertically relative to the connecting member 21, thereby improving the stability of the connection between the connecting member 21 and the slider 22, and also providing guidance for the movement of the slider 22.

[0046] In one embodiment of this implementation, please refer to Figure 6 and Figure 8 The slider 22 has a strip groove 222 extending along the axial direction of the fixing hole 211. The connector 21 cooperates with the strip groove 222. The strip groove 222 is used to limit the distance the slider 22 moves relative to the fixing hole 211.

[0047] Specifically, the connector 21 is provided with a pin 212 and a pin hole 213. The pin hole 213 connects to the fixing hole 211 and penetrates the peripheral wall of the fixing hole 211. The pin 212 passes through the pin hole 213 and engages with the slot 222. The extension direction of the pin 212 is perpendicular to the axial direction of the fixing hole 211. It can be understood that the dimension of the slot 222 in the axial direction of the fixing hole 211 determines the movement distance of the slider 22. By providing the slot 222, the risk of the slider 22 disengaging from the fixing hole 211 can be reduced.

[0048] In one embodiment of this implementation, please refer to Figure 1 , Figure 6 and Figure 9 , Figure 9 yes Figure 6 The diagram shows an enlarged view of a portion of the structure. The support mechanism 10 has a chamber 25 and an opening 26, with the opening 26 connecting to the chamber 25. The bracket 100 also includes a rotating seat 30 and a hook 40. The rotating seat 30 is rotatably connected to the support mechanism 10. The hook 40 is mounted on the rotating seat 30 and is used to fix the cable. The rotating seat 30 can drive the hook 40 to rotate relative to the support mechanism 10, so that the hook 40 can enter and exit the chamber 25 through the opening 26.

[0049] Specifically, the support member 16 encloses to form a cavity 25, and the opening 26 is formed on the support member 16. The support mechanism 10 also includes a fixing frame 17, which is installed on the support member 16. The fixing frame 17 has a hollow part 171, which is aligned with the opening 26. A rotating shaft 172 is provided on the fixing frame 17. The axis of the rotating shaft 172 is the rotation axis of the rotating seat 30. The rotating shaft 172 passes through the hollow part 171, and the rotating seat 30 is rotatably engaged with the rotating shaft 172.

[0050] Understandably, when the display device does not require cable connection, the rotating base 30 can drive the hook 40 to rotate into the cavity 25 so that the hook 40 is hidden, which helps to make the bracket 100 look better. The separate fixed frame 17 and support 16 help to reduce the manufacturing difficulty of the bracket 100.

[0051] In one embodiment of this implementation, please refer to Figure 6 , Figure 7 and Figure 9 , Figure 7 yes Figure 1 A schematic diagram of the structure of the rotating seat 30 and the hook 40; one of the rotating seat 30 and the support mechanism 10 is provided with a protrusion 31, and the other is provided with a slot 13. The protrusion 31 can extend into or out of the slot 13 as the rotating seat 30 rotates. The slot 13 is used to fix the rotating seat 30 relative to the support mechanism 10.

[0052] Specifically, protrusion 31 is disposed on the rotating seat 30, and slot 13 is disposed on the fixed frame 17. It is understood that when slot 13 engages with protrusion 31, it provides force to the rotating seat 30 to restrict its rotation relative to the fixed frame 17. When the user applies external force to the rotating seat 30, protrusion 31 can elastically deform and move out of slot 13, thus allowing unrestricted rotation of the rotating seat 30. This arrangement allows the rotating seat 30 to be fixed in a specific position, improving the user experience. It should be understood that in some other embodiments, slot 13 may also be disposed on the rotating seat 30, and protrusion 31 on the fixed frame 17.

[0053] In one embodiment of this implementation, please refer to Figure 6 , Figure 7 and Figure 9 The rotating seat 30 is provided with two sets of protrusions 31, which are arranged on both sides of the rotation axis of the rotating seat 30. The two sets of protrusions 31 are symmetrically distributed with the rotation axis of the rotating seat 30 as the center. The support mechanism 10 is provided with two sets of slots 13, which are arranged on both sides of the rotation axis of the rotating seat 30. The two sets of slots 13 are symmetrically distributed with the rotation axis of the rotating seat 30 as the center, and the interval between the two sets of protrusions 31 is equal to the interval between the two sets of slots 13.

[0054] Specifically, a set of protrusions 31 includes two protrusions 31, which are spaced apart on the fixed frame 17 along the axis of the rotating shaft 172. The set of protrusions 31 also includes two slots 13, which are spaced apart on the rotating seat 30 along the axis of the rotating shaft 172. A first position and a second position are defined. When the hook 40 is in the first position, it is outside the chamber 25 and can secure the cable. The rotating seat 30 can rotate the hook 40 in the first position by 180 degrees to reach the second position, where it enters the chamber 25.

[0055] It is understandable that the two sets of protrusions 31 are symmetrically distributed around the rotation axis of the rotating seat 30, and the two sets of slots 13 are symmetrically distributed around the rotation axis of the rotating seat 30. The interval between the two sets of protrusions 31 is equal to the interval between the two sets of slots 13. This allows the rotating seat 30 to be restricted from rotating when the hook 40 is in the first or second position, which is beneficial to improving the user experience.

[0056] In one embodiment of this implementation, please refer to Figure 1 and Figure 7 The support mechanism 10 has a second surface 14, and the rotating seat 30 has a third surface 32. The second surface 14 and the third surface 32 are adapted to each other. When the rotating seat 30 rotates to the point where the hook 40 extends into the chamber 25, the second surface 14 and the third surface 32 are flush.

[0057] Specifically, the support mechanism 10 also includes a housing 18, which is cylindrical and surrounds the support member 16 and the guide rail 15. The second surface 14 is the outer circumferential surface of the housing 18, and the third surface 32 is an arc surface with the same radius as the second surface 14. The third surface 32 is located on one side of the rotating member's back hook 40. It is understood that having the third surface 32 as an arc surface with the same radius as the second surface 14, and being located on one side of the rotating member's back hook 40, facilitates the alignment of the second surface 14 and the third surface 32 when the rotating seat 30 rotates to the point where the hook 40 extends into the chamber 25. Aligning the third surface 32 with the second surface 14 improves the aesthetics of the bracket 100.

[0058] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 One end of the hook 40 is connected to the rotating seat 30, and the other end extends along an arc path. The axis of the arc path coincides with the axis of the rotating seat 30, and the size of the opening 26 is adapted to the diameter of the arc path. Specifically, the hook 40 is arc-shaped. It can be understood that the size of the opening 26 being adapted to the diameter of the arc-shaped hook 40 reduces the risk of the hook 40 being obstructed during its entry into the chamber 25 from the opening 26.

[0059] 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.
