[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] As Figures 1 to 9 shown, an embodiment of the present invention provides a monitor bracket. The monitor bracket includes: a fixed arm 10; a moving arm 20 configured to support an object to be installed; a hovering mechanism including a rotating member 50, a spring 31, and a force transmission member 40. The rotating member 50 is rotatably connected to the moving arm 20. One end of the spring 31 is connected to the moving arm 20, and the other end of the spring 31 is connected to the rotating member 50. One end of the force transmission member 40 is connected to the fixed arm 10, and the other end of the force transmission member 40 is rotatably connected to the rotating member 50. Wherein, the moving arm 20 and the fixed arm 10 are movably cooperated with each other, the spring 31 is used to provide a supporting force, and the supporting force of the spring 31 acts on the rotating member 50 to keep the moving arm 20 in any position.

[0029] In the above technical solution, after the object to be installed is installed on the moving arm 20, the gravity of the object to be installed acts on the rotating member 50 through the moving arm 20 and the force transmission member 40, the supporting force of the spring 31 acts on the rotating member 50, and the moments generated by the gravity and the supporting force on the rotating member 50 are equal, so that the rotating member 50 can be kept in any position relative to the moving arm 20, so that the moving arm 20 can be kept in any position relative to the fixed arm 10, thereby realizing the hovering of the object to be installed. In this way, when it is necessary to adjust the position of the object to be installed in the vertical direction, the user can move the moving arm 20 to drive the object to be installed to move through the moving arm 20, so as to adjust the position of the object to be installed. After the user removes the external force on the moving arm 20, the hovering of the object to be installed can be realized again, thereby reducing the complexity of the operation and improving the user experience.

[0030] In the prior art, the display bracket uses a self-locking gas spring as the lifting mechanism. Since the force value of the self-locking gas spring is fixed, it is difficult to adjust according to the change of the load. When the weight of the display does not match the preset force value of the gas spring, the lifting process will become unsmooth and even difficult to control, resulting in a poor lifting experience.

[0031] Therefore, as Figure 4 and Figure 6 shown, in the embodiment of the present invention, the rotating member 50 includes a rotating part 51, a moving part 52 and an adjusting part 53. The first end of the rotating part 51 is rotatably connected to the moving arm 20, the second end of the rotating part 51 is rotatably connected to the force transmission member 40, the adjusting part 53 is rotatably arranged on the rotating part 51, the moving part 52 is located on the outer periphery of the adjusting part 53 and is in threaded cooperation with the adjusting part 53, the moving part 52 is located between the first end and the second end and is rotatably connected to the spring 31, and one end of the adjusting part 53 is exposed outside the moving arm 20 and the fixed arm 10.

[0032] In the above technical solution, on the one hand, by rotating the adjusting part 53, the moving part 52 can drive one end of the spring 31 to move relative to the other end of the spring 31 to stretch or shorten the spring 31, so as to increase or decrease the torque generated by the elastic force, so as to adjust the pre-tightening force of the spring 31, and further enable the cantilever assembly to be able to balance and install objects to be installed with different weights; on the other hand, by exposing one end of the adjusting part 53 outside the moving arm 20 and the fixed arm 10, the adjusting part 53 can be rotated by the wrench 7.

[0033] It should be noted that in the embodiment of the present invention, the fact that one end of the adjusting part 53 is exposed outside the moving arm 20 and the fixed arm 10 means that one end of the adjusting part 53 can be inside the moving arm 20. Through holes are provided on both the fixed arm 10 and the moving arm 20, and both through holes are correspondingly arranged with one end of the adjusting part 53. In this way, the wrench 7 can be inserted into the two through holes to adjust the adjusting part 53; one end of the adjusting part 53 can also extend out of the moving arm 20 and the fixed arm 10 for easy adjustment.

[0034] Preferably, in the embodiment of the present invention, the adjusting part 53 is an adjusting screw.

[0035] As Figure 3 shown, in the embodiment of the present invention, the force transmission member 40 includes: a first rope 42; a guiding member 41 rotatably arranged on the moving arm 20. The guiding member 41 includes a first turntable and a second turntable connected to each other. The outer diameter of the first turntable is greater than or equal to the outer diameter of the second turntable. One end of the first rope 42 is sequentially wound around the first turntable and the second turntable and then rotatably connected to the rotating member 50, and the other end of the first rope 42 bypasses the guiding member 41 and extends out of the moving arm 20 and then is connected to the fixed arm 10.

[0036] With the above settings, on the one hand, the gravity of the object to be installed can be transmitted to the rotating member 50 through the moving arm 20, the guiding member 41, and the first rope 42 to support the object to be installed; on the other hand, after the linear speed of the first rope 42 is converted by the first turntable and the second turntable, the linear speed of the first rope 42 on the first turntable is greater than the linear speed acting on the rotating member 50, thereby facilitating the increase of the moving range of the moving arm 20.

[0037] Specifically, in the embodiment of the present invention, the outer periphery of the first turntable and / or the second turntable is provided with spiral ribs, so that two adjacent turns of the first rope 42 wound thereon can be separated to prevent the two adjacent turns of the first rope 42 from contacting. On the one hand, it can prevent the first rope 42 from breaking due to contact wear during the winding process; on the other hand, it can prevent the first rope 42 from generating abnormal noises during the winding process.

[0038] Preferably, in the embodiment of the present invention, the first turntable and the second turntable are concentrically arranged.

[0039] Preferably, in the embodiment of the present invention, a limit pad 27 is provided on the moving arm 20, and the first rope 42 passes through the moving arm 20 and the limit pad 27 and then is connected to the fixed arm 10.

[0040] In one embodiment, the outer diameter of the first turntable may also be equal to the outer diameter of the second turntable.

[0041] In one embodiment, the first rope 42 may also be replaced with a telescopic connecting rod.

[0042] As Figure 3 shown, in the embodiment of the present invention, the display bracket further includes a guiding member 33, the guiding member 33 is rotatably arranged on the moving arm 20, and the hovering mechanism further includes: a second rope 32, one end of the second rope 32 is connected to the spring 31, and the other end of the second rope 32 is wound around the guiding member 33 and then rotatably connected to the rotating member 50.

[0043] With the above settings, on the one hand, the second rope 32 is guided by the guide member 33, which can prevent the second rope 32 from directly contacting the moving arm 20 or other components, thereby reducing friction and the risk of wear of the second rope 32, and further ensuring the durability of the second rope 32. On the other hand, the guide member 33 can enable the second rope 32 to be compactly arranged inside the moving arm 20, contributing to the compactness of the overall structure. When the monitor bracket is lifted and lowered, it will not increase the additional space occupation due to the disorder of the ropes, which can improve the appearance neatness and space utilization rate of the product. On the further hand, the guide member 33 can effectively prevent the second rope 32 from accidentally coming out or being misaligned during use, and can ensure the correct position of the second rope 32 in any motion state, thereby improving the safety and reliability of the entire hovering mechanism.

[0044] Preferably, in the embodiment of the present invention, the guide member 33 is a pulley, and the pulley is rotatably connected to the moving arm 20 through two pulley connectors 37.

[0045] Specifically, in the embodiment of the present invention, the rotating member 51 includes two rotating plates and a rotating shaft 54, a first connecting shaft 55 and a second connecting shaft 57 arranged between the two rotating plates. The adjusting screw sequentially passes through the rotating shaft 54, the moving member 52 and the second connecting shaft 57 and is connected to the nut. Sliding grooves 56 are provided on both rotating plates, and both ends of the moving member 52 are slidably matched with the two sliding grooves 56. Among them, the two rotating plates are rotatably connected to the moving arm 20 through the rotating shaft 54, the first connecting shaft 55 is connected to the first rope 42, and the rotating member 51 further includes a spring hook 58, and the second rope 32 is connected to the moving member 52 through the spring hook 58.

[0046] Preferably, in the embodiment of the present invention, the two rotating plates are located between two rotating plate connectors 59. Each end of the rotating shaft 54 passes through the corresponding rotating plate and is rotatably connected to the rotating plate connector 59, and the rotating plate connector 59 is connected to the moving arm 20.

[0047] Specifically, in the embodiment of the present invention, one end of the spring 31 is connected to the second rope 32, and a threaded slider is provided at the other end of the spring 31. A screw rod is provided at the bottom end of the moving arm 20, and the threaded slider is in threaded cooperation with the screw rod. By moving the threaded slider, the spring 31 is pre-stretched to the required length.

[0048] In one embodiment, it is also possible not to provide the threaded slider. When installing the product, other tooling is used to stretch the spring 31 to the required length and connect it to the moving arm 20.

[0049] Such as Figure 3 and Figure 5As shown, in the embodiment of the present utility model, the fixed arm 10 is sleeved on the outer periphery of the movable arm 20. A rolling member 23 that can rotate relative to the movable arm 20 is provided on the movable arm 20, and the rolling member 23 is in rolling contact with the inner wall surface of the fixed arm 10. In this way, the friction and wear when the movable arm 20 slides in the fixed arm 10 can be effectively reduced, thereby ensuring the smooth movement of the movable arm 20 and further extending the service life of the monitor bracket.

[0050] As Figure 5 shown, in the embodiment of the present utility model, the monitor bracket further includes a support frame 24 and a pivot shaft 25. The rolling member 23 is a roller, and the roller is installed on the support frame 24 through the pivot shaft 25 and can rotate on the support frame 24. The support frame 24 is provided on the movable arm 20.

[0051] Preferably, in the embodiment of the present utility model, rolling members 23 can be provided at both ends of the movable arm 20, and the number of rolling members 23 at each end of the movable arm 20 is four.

[0052] As Figure 3 and Figure 7 shown, in the embodiment of the present utility model, the movable arm 20 is located inside the fixed arm 10 and is in sliding fit with the fixed arm 10. The movable arm 20 has a first end 21 and a second end 22 that are oppositely arranged, and the first end 21 is configured to support the object to be installed; the monitor bracket further includes a wire-passing member 70, the wire-passing member 70 is connected to the second end 22, the wire-passing member 70 extends away from the movable arm 20 from the second end 22, and a part of the wire-passing member 70 extends into the fixed arm 10. The wire-passing member 70 has a wire-passing channel, and the wire-passing channel is communicated with the inside of the movable arm 20 to guide the wire harness 5.

[0053] In the above technical solution, on the one hand, the wire-passing channel of the wire-passing member 70 is communicated with the inside of the movable arm 20, which can effectively guide the wire harness 5. In this way, the wire harness 5 can be conducted smoothly along the wire-passing channel without being confused or tangled when the movable arm 20 slides; on the other hand, by extending a part of the wire-passing member 70 into the fixed arm 10, it can ensure the smooth passing of the wire harness 5 during the lifting process of the movable arm 20, and can avoid the overlap or compression of the wire harness 5 inside the fixed arm 10, thereby saving the space inside the fixed arm 10, making the whole structure more compact, and improving the space utilization rate of the product.

[0054] Furthermore, hiding the wire harness 5 inside the fixed arm 10 and the movable arm 20 can avoid the exposure of the wire harness 5, which not only improves the aesthetics of the product but also prevents the wire harness 5 from being damaged by the external environment, such as wear and breakage.

[0055] As Figure 2As shown, in an embodiment of the present utility model, the fixed arm 10 includes a first tube body 11, a second tube body 12, and a mounting member 13 for connecting the first tube body 11 and the second tube body 12. The moving arm 20 is slidably engaged with the first tube body 11. The wire-passing member 70 passes through the mounting member 13 from the first tube body 11 and extends into the second tube body 12, and the wire-passing member 70 is slidably engaged with the mounting member 13.

[0056] In the above technical solution, on the one hand, by providing the first tube body 11, the second tube body 12, and the mounting member 13 for connecting the two, the packaging volume can be reduced, making the entire structure easy to transport and store while ensuring strength and stability; on the other hand, the wire-passing member 70 passes through the mounting member 13 from the first tube body 11 and extends into the second tube body 12, and is slidably engaged with the mounting member 13, which can avoid the chaotic entanglement of the wire harness 5 during the lifting process and ensure the smoothness of the moving arm 20 during lifting.

[0057] Furthermore, when the moving arm 20 is lifted or lowered, it can prevent the wire harness 5 (power cord) from overlapping inside the first tube body 11, resulting in the compression of the sliding space.

[0058] It should be noted that in an embodiment of the present utility model, the first tube body 11 and the second tube body 12 are respectively fixedly connected to the mounting member 13 by screws.

[0059] Preferably, in an embodiment of the present utility model, a sheet metal part 14 is provided at the upper end of the first tube body 11. The wire-locking plate 15 is connected to the sheet metal part 14 by screws. The first rope 42 is connected to the wire-locking plate 15, and the decorative cover 16 is covered on the wire-locking plate 15.

[0060] As Figure 3 shown, in an embodiment of the present utility model, the wire-passing member 70 includes a wire-passing tube 72. The wire-passing tube 72 is connected to the second end 22 of the moving arm 20, and a wire-passing channel is formed inside the wire-passing tube 72. In this way, it is convenient for processing.

[0061] Preferably, as Figure 3 shown, in an embodiment of the present utility model, the wire-passing member 70 further includes a connecting member 71 connected to the moving arm 20. The wire-passing tube 72 is connected to the moving arm 20 through the connecting member 71.

[0062] In one embodiment, the wire-passing tube 72 can also be directly welded to the moving arm 20.

[0063] As Figure 3 shown, in an embodiment of the present utility model, a positioning member 60 is provided inside the moving arm 20. The positioning member 60 has a positioning channel for positioning the wire harness 5.

[0064] With the above settings, by fixing the wire harness 5 through the positioning member 60, the wire harness 5 can be prevented from shaking inside the moving arm 20, and the wire harness 5 can be avoided from being wound or disordered during movement, thereby reducing the risk of damage to the wire harness 5.

[0065] Preferably, there are multiple positioning members 60, and the multiple positioning members 60 are arranged at intervals along the axis of the moving arm 20.

[0066] As Figure 3 shown, in the embodiment of the present utility model, the positioning member 60 includes a connecting plate 61 and a baffle 62 arranged at an angle. One end of the connecting plate 61 is connected to the inner wall of the moving arm 20, and the other end of the connecting plate 61 is connected to the baffle 62.

[0067] With the above settings, the baffle 62 and the connecting plate 61 can limit the wire harness 5 to prevent the wire harness 5 from shaking inside the moving arm 20, and the wire harness 5 can be avoided from being wound or disordered during movement, thereby reducing the risk of damage to the wire harness 5.

[0068] As Figure 1 shown, in the embodiment of the present utility model, the display bracket further includes: a base 1; a panel member 3, the moving arm 20 is connected to the panel member 3, and the fixed arm 10 is arranged on the base 1. In this way, by fixing the display on the panel member 3 and moving the moving arm 20, the hovering of the display can be realized.

[0069] Preferably, in the embodiment of the present utility model, the panel member 3 and the moving arm 20 are fixed by screws, and the display is installed on the panel member 3.

[0070] It should be noted that in the embodiment of the present utility model, when the moving arm 20 slides downwards, since one end of the first rope 42 is fixed on the wire locking plate 15, as the moving arm 20 slides down, the first rope 42 is stretched, causing the guiding member to rotate. The rotation of the guiding member is transmitted to the rotating member through the first rope 42, causing the rotating member 50 to rotate; at the same time, one end of the second rope 32 is connected to the spring 31, and the other end of the second rope 32 is connected to the rotating member 50 through the moving member 52. When the rotating member 50 rotates, the second rope 32 will stretch the spring 31 to generate a torque opposite to gravity; among them, to achieve free hovering at any position, it is necessary to make the torque generated by the gravity of the display equal to the torque generated by the spring 31 at any height, and the appropriate spring force value and other design parameters can be determined through computer simulation analysis.

[0071] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: After the object to be installed is installed on the moving arm, the gravity of the object to be installed acts on the rotating member through the moving arm and the force transmission member, the supporting force of the spring acts on the rotating member, and the moments generated by the gravity and the supporting force on the rotating member are equal, which can enable the rotating member to remain in any position relative to the moving arm, so that the moving arm can remain in any position relative to the fixed arm, thereby realizing the hovering of the object to be installed. In this way, when it is necessary to adjust the position of the object to be installed in the vertical direction, the user can move the moving arm to drive the object to be installed to move, so as to adjust the position of the object to be installed. After the user removes the external force on the moving arm, the hovering of the object to be installed can be realized again, thereby reducing the complexity of the operation and improving the user experience.

[0072] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
