Description

Technical Field

[0001] The present invention relates to the technical field of cantilever brackets, and in particular to a cantilever bracket. Background Art

[0002] The cantilever bracket design focuses on providing stable support, but with the widespread adoption of applications such as live streaming and online conferencing, users have higher expectations for interactivity and additional functionality. For example, they can quickly adjust the volume of audio output devices such as headphones and speakers without touching the equipment, and flexibly control the bracket's lighting components to create a suitable environment.

[0003] In the prior art, the volume control of audio output devices generally requires the use of physical buttons on the audio output device body or a computer software interface for adjustment (in live broadcasts, online meetings and other similar scenarios, most audio output devices need to be connected to a computer), and light source adjustment (such as indicator brightness and decorative lighting effects) may be independent of the bracket (for example, the light-emitting component is connected to an external lighting effect adjustment controller). In this way, when users adjust the volume or change the light source effect on the bracket, they need to operate different devices or control buttons on the interface separately, which not only increases the complexity of use, but may also reduce efficiency due to cumbersome operations.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] The invention provides a cantilever bracket, which can adjust the volume of an audio output device connected to a computer, one of the lighting effects at an upper arm component, a lower arm component and a bracket joint, and can adjust the joint damping.

[0042] like Figures 1 to 17As shown, an embodiment of the present invention provides a cantilever bracket, which includes: an upper arm assembly, including an upper arm 11, one end of the upper arm 11 is used to install an electronic device; a lower arm assembly, including a lower arm 21; a first joint assembly, including a first rotating member 12 and a first connecting member 22, the first rotating member 12 is connected to the upper arm 11, the first connecting member 22 is connected to the lower arm 21, the first rotating member 12 is rotatably arranged relative to the first connecting member 22, and at least one of the upper arm assembly, the lower arm assembly and the first joint assembly is provided with a light source assembly; a control knob 71, the control knob 71 is communicatively connected to the computer, the control knob 71 is set on the upper arm assembly or the lower arm assembly, the control knob 71 includes a pressing portion and a rotating portion, pressing the pressing portion can switch between a volume adjustment mode and a light effect adjustment mode, and rotating the rotating portion can adjust the output volume of the computer, the light effect color of the light source assembly and at least one of the light effect modes of the light source assembly.

[0043] Specifically, a control cable can be used to connect the control knob 71 and the light source assembly in series, with one end of the cable connected to a computer. The control cable can transmit both control signals and power. The computer can be a desktop computer or a laptop. For example, one end of the control cable is connected to a USB port on the computer, and the audio output device is also connected to the computer. The control knob 71 can be used to adjust the output volume of the computer, thereby adjusting the volume of the audio output device.

[0044] In the above technical solution, a light source assembly is integrated on the cantilever bracket, and a control knob 71 is arranged on the upper arm assembly or the lower arm assembly. The control knob 71 is connected to the computer for communication, and it has a pressing part and a rotating part. The user only needs to press the control knob 71 to switch freely between the volume adjustment mode and the light effect adjustment mode. By rotating the rotating part of the control knob 71, the volume of the audio output device connected to the computer or the light effect mode or light effect color of the light source assembly on the cantilever bracket can be adjusted. In this way, a control knob 71 can be used to adjust the volume of audio output devices such as headphones and speakers or adjust the light effect of the light source assembly, thereby avoiding the need to operate control buttons on different devices or interfaces separately, thereby simplifying the operation process, which can not only improve operation efficiency, but also improve operation convenience to enhance user experience.

[0045] It should be noted that, in the embodiment of the present invention, the electronic device is a microphone.

[0046] In some embodiments, after the control knob 71 is not operated for a long time, it automatically switches to the volume adjustment mode. Press the pressing part once to switch to the silent mode. At this time, the computer is in silent state, so that the audio output device is in silent state; press the pressing part twice to enter the light effect adjustment mode. At this time, rotating the rotating part clockwise can enter the light effect color adjustment mode, light effect breathing mode, light effect fantasy mode, light effect streamer mode or light effect constant light mode, etc., and rotating the rotating part counterclockwise can enter the color switching mode in the light effect adjustment mode; press the pressing part twice again or after a certain preset time (for example, 10 seconds) when the control knob 71 is not operated, it returns to the volume adjustment mode. At this time, rotating the rotating part clockwise increases the output volume of the computer, and rotating the rotating part counterclockwise decreases the output volume of the computer, thereby adjusting the volume of the audio output device connected to the computer. Of course, in other embodiments, other light effect modes and volume adjustment modes may also be included, such as light effect and light intensity adjustment modes, which are not listed here one by one.

[0047] Since the upper arm assembly of the cantilever bracket needs to rotate relative to the lower arm assembly to adjust the height of the microphone, frequent rotation will loosen the joint, making it impossible to achieve the microphone's high degree of free hovering. Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the cantilever bracket further includes: a damping adjustment assembly includes a locking member 30 and a knob member 40, the knob member 40 is rotatably connected to the first rotating member 12, the knob member 40 is located on the side of the first rotating member 12 away from the first connecting member 22, the locking member 30 passes through the first connecting member 22 and the first rotating member 12 and is transmission-connected to the knob member 40, and when the knob member 40 is rotated, the locking member 30 drives the first connecting member 22 away from or close to the first rotating member 12 to adjust the damping between the first connecting member 22 and the first rotating member 12.

[0048] In the above technical solution, when the user rotates the knob member 40, the locking member 30 moves accordingly, causing the first connecting member 22 to move away from or approach the first rotating member 12, thereby changing the contact pressure and friction between the first connecting member 22 and the first rotating member 12 to achieve the purpose of adjusting the damping. In this way, the user can control the smoothness of rotation between the upper arm 11 and the lower arm 21 to ensure the flexibility of joint adjustment; and during use, the user can easily fine-tune the position of the microphone by rotating the knob member 40 without worrying about the joint being loose or too tight.

[0049] like Figure 1 、 Figure 6 and Figure 8As shown, in an embodiment of the present invention, the locking member 30 includes: a pressing member 31, which abuts against the side of the first connecting member 22 facing away from the first rotating member 12; a fitting member 32, which is connected to the pressing member 31, and the fitting member 32 cooperates with the thread of the knob member 40 to drive the locking member 30 to move relative to the first rotating member 12 along the rotation axis of the knob member 40 by rotating the knob member 40.

[0050] In the above technical solution, through the threaded connection between the mating part 32 and the knob member 40, the force of rotating the knob member 40 is converted into linear adjustment of the locking member 30, ensuring the smoothness and accuracy of the operation, and avoiding the problems of poor feel or low adjustment accuracy often encountered in traditional damping adjustment methods; in addition, during use, the user only needs to gently rotate the knob member 40 to immediately feel the change in resistance at the joint, thereby easily adjusting the height and angle of the microphone without having to worry about the joint being too loose or difficult to adjust.

[0051] Furthermore, when the user rotates the knob member 40, the knob member 40 and the mating member 32 move relative to each other, driving the locking member 30 to move axially along the rotation axis of the knob member 40. During this movement, the pressing member 31 applies greater pressure or reduces pressure on the first connecting member 22 according to the rotation direction of the knob member 40, thereby realizing dynamic adjustment of the joint damping.

[0052] like Figure 3 As shown, a nut 88 is provided on the knob component 40 , and the fitting 32 is passed through the nut 88 and threadably engaged with the nut 88 .

[0053] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, a conical surface is provided on the outer periphery of the clamping member 31, and a conical hole 221 is provided on the first connecting member 22. Along the rotation axis, from the first connecting member 22 to the first rotating member 12, the inner diameter of the conical hole 221 gradually decreases, and the conical surface abuts against the inner wall surface of the conical hole 221.

[0054] In the above technical solution, the contact surface between the conical surface and the conical hole automatically adjusts the contact area as the clamping member 31 moves axially, thereby obtaining a larger damping adjustment range under a smaller operating force, ensuring that the joint can still maintain a good feel and stability during long-term repeated use, while also reducing the risk of joint relaxation caused by improper adjustment; specifically, when the user rotates the knob component 40, the threaded engagement of the mating member 32 and the knob component 40 prompts it to move along the direction of the rotation axis, thereby driving the conical surface of the clamping member 31 to advance or withdraw in the conical hole 221 of the first connecting member 22. This axial movement is converted into an increase or decrease in the friction force between the conical surface and the inner wall of the conical hole, thereby realizing seamless adjustment of the joint damping to offset the difference between the spring force and gravity, and better realize the high hovering of the microphone; and due to the conical surface design, a smaller rotational force of the knob component 40 can achieve a larger friction force.

[0055] In one embodiment, the side of the pressing member 31 facing the first connecting member 22 is provided with a first stepped end surface, and the first connecting member 22 is provided with a second stepped end surface, and the first stepped end surface abuts the second stepped end surface. In this way, the friction between the first and second stepped end surfaces can be adjusted, thereby adjusting the joint damping.

[0056] like Figure 2 、 Figure 6 and Figure 8 As shown, in an embodiment of the present invention, the locking member 30 also includes a connecting member 33 for connecting the pressing member 31 and the mating member 32, and a first through hole 121 is provided on at least one of the first rotating member 12 and the first connecting member 22. The connecting member 33 is movably arranged in the first through hole 121, and the connecting member 33 is engaged with the first through hole 121 to prevent rotation.

[0057] In the above technical solution, by setting the first through hole 121, a moving space can be provided for the connecting member 33, and a rotation-stopping fit can be formed therewith, that is, the connecting member 33 can move freely in the first through hole 121, but cannot rotate by itself, which can ensure that the overall movement direction of the locking member 30 is consistent with the rotation instruction of the knob member 40. When the user rotates the knob member 40 to operate, due to the threaded transmission between the fitting member 32 and the knob member 40, the knob member 40 drives the fitting member 32 to move along the rotation axis of the knob member 40, and transmits it to the clamping member 31 without rotational deviation through the connecting member 33, causing the conical surface of the clamping member 31 to produce a tighter or looser contact with the inner wall surface of the conical hole 221 of the first connecting member 22, thereby controlling the damping force between the first connecting member 22 and the first rotating member 12.

[0058] Preferably, in an embodiment of the present invention, a plane is provided on the connecting member 33 , and an inner wall of the first through hole 121 is provided with a plane that matches the plane on the connecting member 33 to achieve anti-rotation fit.

[0059] like Figure 4 and Figure 5 As shown, in the embodiment of the present invention, at least one of the first rotating member 12 and the first connecting member 22 is provided with a mounting groove 13, and a light source assembly is provided in the mounting groove 13. In this way, the light source assembly can be installed.

[0060] like Figure 1 、 Figure 3 and Figure 6 As shown, in an embodiment of the present invention, a light source assembly is provided on both the first rotating member 12 and the first connecting member 22, the light source assembly includes a light source member 51, the light source member 51 includes a circuit board and a light source arranged on the circuit board, a second through hole 34 is provided on the locking member 30, and the cantilever bracket also includes a flexible electrical connector 78, the flexible electrical connector 78 is passed through the second through hole 34, one end of the flexible electrical connector 78 extends into the mounting groove 13 on the first rotating member 12 and is electrically connected to the circuit board, and the other end of the flexible electrical connector 78 extends into the mounting groove 13 on the first connecting member 22 and is electrically connected to the circuit board.

[0061] In the above technical solution, a second through hole 34 is provided on the locking member 30, which can provide a passage for the flexible electrical connector 78 to pass through, so that the flexible electrical connector 78 can connect the first rotating member 12 and the light source circuit on the first connecting member 22. In this way, during use, the user can freely adjust the position of the microphone, whether it is a change in height or angle. The flexible electrical connector 78, with its excellent ductility and conductive properties, can ensure the normal power supply and stable operation of the light source assembly, and even in the case of frequent joint movements, it can avoid the breakage or poor contact problems that may occur in traditional hard wiring.

[0062] Furthermore, when the upper arm assembly rotates relative to the lower arm assembly, the upper arm assembly, the circuit board in the first rotating member 12, the locking member 30, the knob member 40 and one end of the flexible electrical connector 78 connected to the circuit board rotate together relative to the lower arm assembly, and the conical surface of the locking member 30 rotates in friction with the conical surface of the first connecting member 22 to provide resistance; because the flexible electrical connector 78 passes through the center position and passes through the interior of the locking member 30 to connect with the circuit board of the first connecting member 22, its rotation amplitude is small, and the surrounding space is sufficient, there is no friction cutting line, and the connection is stable and reliable; at this point, the two circuit boards are interconnected.

[0063] Preferably, in an embodiment of the present invention, the light source is a plurality of lamp beads, and the flexible electrical connector 78 is a flexible flat cable.

[0064] Preferably, in the embodiment of the present invention, one end of the second through hole 34 is opened on a plane on the connecting member 33 .

[0065] like Figure 1 and Figure 5 As shown, in an embodiment of the present invention, a control knob 71 is located at an end of the upper arm 11 away from the first rotating member 12; the cantilever bracket further includes: a control member, including a control board 72 and a control harness 73. The control board 72 is located at an end of the upper arm 11 away from the first rotating member 12. The control knob 71 is connected to the control board 72 for control. One end of the control harness 73 is electrically connected to the control board 72, and the other end of the control harness 73 is connected to a circuit board within the first rotating member 12. A power harness 74 is located on the lower arm 21. One end of the power harness 74 is electrically connected to the circuit board within the first connecting member 22, and the other end of the power harness 74 is configured to connect to a computer. For example, the end of the power harness 74 can be plugged into a USB port on the computer.

[0066] In the above technical solution, the control knob 71 is placed at one end of the upper arm 11 away from the first rotating member 12, so as to facilitate intuitive operation without being affected by the movement of the cantilever bracket joint. The upper arm 11 also carries the control member, wherein the control board 72 is control-connected to the control knob 71, so that the user can adjust the volume of the electronic device or adjust the light effect of the light source assembly by rotating the control knob 71. One end of the control harness 73 is electrically connected to the control board 72, and the other end of the control harness 73 extends to the inside of the first rotating member 12 and is electrically connected to the circuit board therein, and the flexible electrical connector 78 can be electrically connected to the first rotating member.

[0067] Preferably, in an embodiment of the present invention, the electronic device is a microphone, and the electronic device is electrically connected to the control board 72 .

[0068] It should be noted that, in the embodiment of the present invention, the control panel 72, the control knob 71, and the connection method between the control panel 72 and the control knob 71 can all adopt existing technologies, which will not be described in detail here.

[0069] Preferably, in an embodiment of the present invention, the control harness 73 is arranged in the upper arm 11, the circuit board in the first rotating member 12 is connected to the circumferentially evenly distributed lamp beads, and the circuit board is fixed in the first rotating member 12 with screws. There is a certain space between the lamp beads on the circuit board and the knob member 40, and the light emitted by the lamp beads can pass through the middle part of the knob member 40 (the light-transmitting area 41). The first rotating member 12 is provided with a first avoidance through-hole 124, and the control harness 73 passes through the first avoidance through-hole 124 and enters the mounting groove 13; the lamp beads are evenly distributed on the circumference of the circuit board in the first connecting member 22, the screws pass through the light-transmitting plate, and the circuit board is fixed in the first connecting member 22, and the light emitted by the lamp beads on the circuit board can pass through the light-transmitting plate. One end of the power harness 74 has a USB port for external power supply, and the other end passes through the second avoidance through-hole 222 on the first connecting member 22 and is connected to the circuit board in the first connecting member 22. The lower arm 21 is provided with a mounting groove 211 for mounting the power harness 74, and the second avoidance through-hole 222 is connected to the mounting groove 211.

[0070] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, in an embodiment of the present invention, the light source assembly includes: a light source component 51, which is installed in the installation groove 13; a semi-reflective and semi-transparent element 53; and a reflective element 54. Along the axis of the first rotating member, the light source component 51, the reflective element 54 and the semi-reflective and semi-transparent element 53 are sequentially arranged on the first connecting member 22 and / or the first rotating member 12, and a reflecting surface is provided on the side of the reflective element 54 facing the semi-reflective and semi-transparent element 53. The light emitted by the light source component is incident on the semi-reflective and semi-transparent element 53 through the outer periphery of the reflective element 54.

[0071] In the above technical solution, the light source component 51 serves as the core unit for emitting the initial light and is placed in the mounting groove 13 of the first rotating component 12 or the first connecting component 22. The light starts from the light source component 51, first hits the reflector 54 and bypasses the outer periphery of the reflector 54 to guide to the semi-reflective and semi-transparent component 53. After the light enters the semi-reflective and semi-transparent component 53, since the semi-reflective and semi-transparent component 53 has the dual functions of refraction and reflection, part of the light is able to penetrate the semi-reflective and semi-transparent component 53, while the other part of the light is reflected back to the reflecting surface of the reflector 54, so that the light repeatedly shuttles between the reflector 54 and the semi-reflective and semi-transparent component 53, forming a light cycle. In this way, each time the light passes through the semi-reflective and semi-transparent component 53, part of the light gradually diffuses to the outside, and the remaining light is reflected again, thereby forming an infinite mirror phenomenon.

[0072] like Figure 1 、 Figure 5 and Figure 6As shown, in an embodiment of the present invention, a light source assembly is provided on the first connecting member 22, and the light source assembly also includes a light-transmitting member 52 for transmitting light. The light-transmitting member 52 is installed in the installation groove 13 and is spaced apart from the light source member 51. The reflector 54 is provided on the side of the light-transmitting member 52 away from the light source member 51, and the positive projection of the reflector 54 on the light-transmitting member 52 is located within the range of the light-transmitting member 52.

[0073] In the above technical solution, the light source component 51 is arranged in the mounting groove 13 as the starting point of the light, and is spaced apart from the light-transmitting component 52, so as to ensure that the light has enough space for preliminary diffusion and homogenization before reaching the light-transmitting component 52, and the reflector 54 is located on the side of the light-transmitting component 52 away from the light source component 51, and its positive projection on the light-transmitting component 52 is completely within the range of the light-transmitting component 52. In this way, it can be ensured that the light emitted from the light source component 51 on the first connecting component 22 can pass through the light-transmitting component 52 and the edge of the reflector 54 into the semi-reflective and semi-transparent component 53 to form annular light, thereby realizing the infinite mirror effect of the annular light.

[0074] Preferably, in an embodiment of the present invention, the reflective member 54 is a mirror panel, one side of which has adhesive backing 83, and the other side is a mirror surface and is opaque. The mirror panel is attached to the knob component 40 or the light-transmitting component 52. The diameter of the mirror panel will be smaller than the diameter of the light-transmitting part of the knob component 40 or the light-transmitting component 52, so the light transmitted is annular; the semi-reflective and semi-transparent member 53 is a semi-transparent plate, which can transmit light and reflect light. It is correspondingly attached to the knob component 40 or the first connecting member 22. There is a gap between the mirror panel and the semi-transparent plate. The transmitted annular light can be repeatedly reflected between the semi-transparent plate and the mirror panel to form an infinite mirror effect.

[0075] like Figure 1 As shown, in an embodiment of the present invention, a light source assembly is provided on the first rotating member 12, the knob member 40 is covered in the mounting groove 13, the knob member 40 has a light-transmitting area 41 for transmitting light, and the reflector 54 is arranged on the side of the knob member 40 facing away from the light source member, and the positive projection of the reflector 54 on the light-transmitting area 41 is within the range of the light-transmitting area 41.

[0076] Through the above arrangement, it can be ensured that the light emitted from the light source component 51 on the first rotating component 12 can be injected into the semi-reflective and semi-transparent component 53 through the light-transmitting area 41 and the edge of the reflector 54 to form an annular light, thereby realizing the infinite mirror effect of the annular light.

[0077] like Figure 1 and Figure 4As shown, in an embodiment of the present invention, when a light source assembly is provided on the first rotating member 12, the knob member includes: an annular handle 42 having an internal through hole, the annular handle 42 does not transmit light; a light-transmitting body connected to the inner wall surface of the internal through hole, the light-transmitting body forming a light-transmitting area 41.

[0078] In the above technical solution, the ring handle 42 is convenient for users to operate, and its non-light-transmitting property ensures that users will not be directly exposed to the internal light source during operation, reducing light interference and improving the user experience; the light-transmitting body is connected to the inner wall surface of the through hole inside the ring handle 42, forming a light-transmitting area 41, which can make the light emitted by the light source component 51 evenly transmit from the light-transmitting area 41.

[0079] like Figure 7 As shown, in the embodiment of the present invention, an assembly groove is provided on the lower arm 21, and the lower arm assembly also includes: a light-emitting component 75, including a plurality of light-emitting components, and the plurality of light-emitting components are sequentially arranged in the assembly groove along the extension direction of the lower arm 21; a reflective portion 76, which is arranged between the bottom wall of the assembly groove and the light-emitting component 75, and a reflective surface is provided on the side of the reflective portion 76 facing the light-emitting component 75; a light-transmitting portion 77, which is used to transmit light, and the light-transmitting portion 77 is covered on the assembly groove, and the light-transmitting portion 77 is located on the side of the light-emitting component 75 away from the reflective portion 76.

[0080] In the above technical solution, multiple light-emitting parts are arranged in sequence according to the extension direction of the lower arm 21, ensuring the continuity and uniformity of light along the length direction of the lower arm 21, so as to enhance the overall visual experience; in addition, a reflective portion 76 is provided between the light-emitting component 75 and the bottom wall of the assembly groove. The reflective surface can effectively capture and guide the light from the light-emitting part, so that the light is reflected by the reflective surface and then emitted from the direction of the light-transmitting portion 77. In this way, the loss of light energy can be reduced, the lighting efficiency can be improved, and the waste of diffused light can be avoided, thereby maximizing the utilization of light energy.

[0081] Preferably, in an embodiment of the present invention, the light-emitting component 75 is a light strip having a plurality of light-emitting elements, and the light-transmitting portion 77 is a light-transmitting plate.

[0082] Preferably, in an embodiment of the present invention, there are two light-transmitting portions 77, the first of the two light-transmitting portions 77 is affixed with a light strip, and the second of the two light-transmitting portions 77 is located on the side of the first light-transmitting portion 77 away from the light strip, and the light strip emits light toward the reflective portion 76, and the light shines on the reflective portion 76, and is reflected and emitted through the two light-transmitting portions 77 in sequence. In this way, the outside cannot see the bright particles of the lamp beads, nor can the shadow surface on the back of the light strip be seen, thereby making the light uniform and beautiful, wherein the light-transmitting portion 77 is a light-transmitting plate, and the reflective portion 76 is a reflective film, and the line of the light strip passes through the first connecting member 22 of the lower arm assembly and is connected to the circuit board in the first connecting member 22, so that the rotation of each joint has no effect on it.

[0083] Since the lifting of the cantilever bracket in the prior art is mainly achieved by clamping the joints to provide friction, the lifting experience is poor. The cantilever bracket provided by the present invention can freely hover at a certain height. Figure 8 、 Figure 9 、 Figure 10 and Figure 12 As shown, in the embodiment of the present invention, the first rotating member 12 includes a first base 123 and a first guide portion 122, the first base 123 is connected to the upper arm 11, and the first guide portion 122 is connected to the side of the first base 123 facing the lower arm 21, and the cantilever bracket further includes: a base assembly, including a base 19; a second joint assembly, including a second connecting member 18 and a second rotating member 14, the second rotating member 14 is connected to the lower arm 21, the second connecting member 18 includes a second base 181 and a second guide portion 182, the second base 181 is connected to the base 19, and the second guide portion 1 82 is connected to the side of the second base 181 facing the lower arm 21, and the second rotating member 14 is rotatably connected to the second base 181; the first guide portion 122 and the second guide portion 182 both have eccentric outer peripheral surfaces; the force member 60 is arranged on the lower arm 21, and the first end of the force member 60 is wrapped around the eccentric outer peripheral surface of the second guide portion 182 and acts on the second guide portion 182 or the base 19, and the second end of the force member 60 is wrapped around the eccentric outer peripheral surface of the first guide portion 122 and acts on the first guide portion 122, and the force member 60 provides a supporting force to the upper arm 11 to maintain it at any position.

[0084] In the above technical solution, one end of the force-applying member 60 is wrapped around the eccentric outer peripheral surface of the first guide portion 122 and acts on the first base 123. The other end of the force-applying member 60 bypasses the eccentric outer peripheral surface of the second guide portion 182 and acts on the second guide portion 182 or directly contacts the base 19. In this way, the second guide portion 182 or the base 19 provides a pulling force to the upper arm 11 through the force-applying member 60. The force-applying member 60 is respectively wrapped around the second guide portion 182 and the first guide portion 122 to stretch and provide a pulling force to balance the gravity of the microphone, so that no matter what position the upper arm 11 is in, the force-applying member 60 can continuously provide a supporting force to the upper arm 11 through its own elasticity and tension to balance the gravity of the microphone, so that the microphone can freely hover at any set height without the need for an additional locking device, thereby achieving smooth height adjustment.

[0085] like Figure 8 and Figure 11As shown, in one embodiment, the damping is also adjusted between the second connecting member 18 and the second rotating member 14 by a damping adjustment assembly. A tapered hole 221 is provided on the second rotating member 14. Along the rotation axis, from the second connecting member 18 to the second rotating member 14, the inner diameter of the tapered hole 221 gradually decreases. The conical surface of the pressing member abuts against the inner wall surface of the tapered hole 221. At least one of the first rotating member 12 and the first connecting member 22 is provided with a first through hole 121. The fitting member 32 is movably arranged in the first through hole 121. The fitting member 32 is locked in rotation with the first through hole 121. The pressing member 31 abuts against the second rotating member. On the side of the component 14 facing away from the second connecting member 18, the knob component 40 includes a knob portion 44 and a connecting portion 43 connected to the knob portion 44. The knob portion 44 is rotatably connected to the second connecting member 18. The knob portion 44 is located on the side of the second connecting member 18 facing away from the second rotating member 14. The connecting portion 43 penetrates the second connecting member 18 and the second rotating member 14 and is threadedly connected to the matching component 32 of the knob component 40. When the knob portion 44 is rotated, the locking member 30 drives the second rotating member 14 away from or close to the second connecting member 18 to adjust the damping between the second rotating member 14 and the second connecting member 18.

[0086] Through the above arrangement, when the user rotates the knob component 40, the threaded connection between the connecting portion 43 and the mating component 32 will drive the mating component 32, prompting the mating component 32 to move along the axial direction in the first through hole 121, and causing the mating component 32 to drive the clamping component 31 to move in the same direction, so that the contact area between the conical surface of the clamping component 31 and the inner wall of the conical hole of the second rotating component 14 increases or decreases, thereby controlling the pressure applied by the clamping component 31 to the second rotating component 14, and further regulating the friction resistance between the second rotating component 14 and the second connecting component 18. In this way, the difference between the spring force and the gravity can be offset, and the microphone can be better hovered at a high position.

[0087] like Figure 8 、 Figure 9 and Figure 10 As shown, in the embodiment of the present invention, the second guide portion 182 has a first arc surface 141 (the eccentric outer peripheral surface of the second guide portion 182), and the first arc surface 141 is arranged around the rotation axis L1 between the second connecting member 18 and the second rotating member 14, and the distance between the rotation axis L1 and the first arc surface 141 gradually increases from the first end of the force member 60 to the second end of the force member 60; the first guide portion 122 has a second arc surface 142 (the eccentric outer peripheral surface of the first guide portion 122), and the second arc surface 142 is arranged around the rotation axis L2 of the first rotating member 12 and the first connecting member 22, and the distance between the rotation axis L2 and the second arc surface 142 gradually increases from the first end of the force member 60 to the second end of the force member 60.

[0088] Through the above-mentioned arrangement, the distance between the first arc surface 141 and the second arc surface 142 and their respective rotation axes gradually increases from the first end of the force-applying member 60 to the second end of the force-applying member 60. This progressive arc surface change ensures that the force-applying member 60 can generate varying supporting forces at different rotation angles, thereby realizing self-balancing of the cantilever bracket at any position to enhance the user experience.

[0089] Preferably, in the embodiment of the present invention, the first guide portion 122 and the second guide portion 182 are both cams or eccentric wheels, and the outer peripheral wall of the cam or eccentric wheel forms the eccentric outer peripheral surface.

[0090] like Figure 8 As shown, in the embodiment of the present invention, the force-applying member 60 includes: an elastic member 61, which is provided on the lower arm 21; a first flexible member 62, one end of the first flexible member 62 is connected to one end of the elastic member 61, and the other end of the first flexible member 62 passes through the second guide portion 182 and passes through the wire hole 89 on the second connecting member to be installed on the base 19; a second flexible member 63, the second flexible member 63 is connected to the other end of the elastic member 61, and the other end of the second flexible member 63 is wrapped around the first guide portion 122 and installed on the first base 123. In this way, at different rotation angles of the upper arm 11, by stretching the elastic member 61, the force-applying member 60 can generate a varying supporting force. Among them, the first flexible member 62 and the second flexible member 63 are pull ropes, and the elastic member 61 is a spring.

[0091] In the above embodiment, when the lower arm assembly is rotated, the first flexible member 62 is wrapped around the second guide portion 182 to stretch the spring, and different spring stretching amounts correspond to different rotation angles of the lower arm, so the overall effect is relatively balanced, and the lifting and lowering experience is good; the second flexible member 63 is wrapped around the first guide portion 122, and the upper arm assembly is rotated, and the spring is also stretched by the second flexible member 63, and different spring stretching amounts correspond to different rotation angles of the upper arm, so the overall effect is relatively balanced, and the lifting and lowering experience is good; the first flexible member 62 and the second flexible member 63 stretch the spring by wrapping around the second guide portion 182 and the first guide portion 122 to provide spring force to balance the gravity of the microphone.

[0092] Preferably, in the embodiment of the present invention, one end of the second flexible member 63 passes through the first connecting member 22 and is installed on the first rotating member 12 .

[0093] like Figure 8 and Figure 13 As shown, in an embodiment of the present invention, a mounting through hole is provided on the base 19, and the force-applying member 60 further includes an adjusting member 81 and a fixing member 82. The fixing member 82 is movably arranged in the mounting through hole, and one end of the fixing member 82 is connected to the end of the first flexible member 62 away from the elastic member 61, and the other end of the fixing member 82 is screwed together with the adjusting member 81, and the adjusting member 81 is visible through the mounting through hole.

[0094] With the above arrangement, the user can rotate the adjusting member 81 to move the fixing member 82. Since one end of the first flexible member 62 is connected to the fixing member 82, when adjusting the adjusting member 81, the initial extension of the elastic member 61 can be stretched by the first flexible member 62, thereby changing the initial force of the elastic member 61 to accommodate microphones of different weights or fine-tune the balance of the bracket, thereby increasing the adaptability of the cantilever bracket. The fixing member 82 is an adjustment nut, and the adjusting member 81 is an adjustment screw.

[0095] like Figure 8 and Figure 10 As shown, in this embodiment of the present invention, the force-applying member 60 further includes a first stopper 64, which is connected to the end of the second flexible member 63 that is away from the elastic member 61. A stopper groove 65 is provided on the side of the first rotating member 12 that faces the lower arm 21, and the first stopper 64 engages with the stopper groove 65 to limit the position. In this way, the end of the second flexible member 63 that is away from the elastic member 61 can be fixed to the first rotating member 12.

[0096] like Figure 13 As shown, in the embodiment of the present invention, the force-applying member 60 further includes a second limiting member 66, which is connected to the first flexible member 62 and is installed in the fixing member 82 to connect the fixing member 82 to the first flexible member 62. The first limiting member 64 and the second limiting member 66 are both limiting posts.

[0097] like Figure 10 As shown, in this embodiment of the present invention, the cantilever assembly further includes a stopper 67 located on the side of the first rotating member 12 facing the lower arm 21. The stopper 67 covers the retaining groove 65 and is detachably connected to the first rotating member 12. This prevents the first retaining member 64 from falling out of the retaining groove 65, thereby preventing spring failure. The stopper 67 is fastened to the first rotating member 12 by a screw.

[0098] like Figure 9 、 Figure 14 and Figure 15 As shown, in an embodiment of the present invention, the base assembly further includes: a base 15; a rotating shaft 16, connected to the base 19; a locking member 17, located between the base 19 and the base 15, and the rotating shaft 16 passes through the locking member 17 and rotates with the base 15, and the locking member 17 is movably arranged along the radial direction of the rotating shaft 16, and the locking member 17 has a locking position that is limited by the rotating shaft 16 and an unlocking position that is separated from the rotating shaft 16.

[0099] In the above technical solution, the rotating shaft 16 is rotatably matched with the base 15, and the base 19 can rotate relative to the base 15, which increases the rotational freedom around the rotating shaft 16 for the cantilever bracket, allowing the microphone to be flexibly adjusted according to the needs of the user; and when the locking member 17 is in the locked position, the locking member 17 cooperates with the rotating shaft 16 to fix the rotating shaft 16, preventing the rotating shaft 16 and the base 19 connected to the rotating shaft 16 from rotating, ensuring that the cantilever bracket is stable and motionless after the user completes the adjustment, avoiding unnecessary shaking and noise interference; pushing the locking member 17 to the unlocked position releases the limit between the locking member 17 and the rotating shaft 16, and the user can rotate the rotating shaft 16 and the base 19 connected to the rotating shaft 16 to achieve rapid repositioning of the entire bracket to adapt to a better recording angle or to adapt to a different workspace layout. After completing the position adjustment, it is only necessary to push the locking member 17 back to the locked position to fix the base 19 through the limit cooperation between it and the rotating shaft 16.

[0100] like Figure 8 As shown, in the embodiment of the present invention, the base assembly further includes a base gasket 84 and a compression spring 85. The locking member 17 is a locking plate. One end of the locking plate is exposed to the outside for pressing, and the other end cooperates with the compression spring 85 to press against the base 15. The base gasket 84 is then mounted on top and locked with a screw. In this way, the locking plate can be pressed to move. The locking plate has a waist hole, and the corresponding position of the rotating shaft 16 has a groove. When the locking plate is pressed, the waist hole on the locking plate moves, exposing the hole on the base 15, and the rotating shaft 16 can be inserted into the base 15. When the locking plate is released, the locking plate moves back under the action of the compression spring 85, so that the locking plate can be stuck in the groove of the rotating shaft 16 to achieve the locking function. The base 19 will not be able to be pulled out, thus achieving the quick release function.

[0101] Preferably, in an embodiment of the present invention, the base 15 is clamped on the desktop, and a connector 87 is provided on the end of the upper arm 11 away from the first joint assembly. The connector 87 has a ball screw 86 for connecting to a microphone.

[0102] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: a light source assembly is integrated on the cantilever bracket, and the control knob is arranged on the upper arm assembly or the lower arm assembly. The control knob is connected to the computer for communication, and it has a pressing part and a rotating part. The user only needs to press the control knob to switch freely between the volume adjustment mode and the light effect adjustment mode. By rotating the rotating part of the control knob, the volume of the audio output device connected to the computer can be adjusted or the light effect mode or light effect color of the light source assembly on the cantilever bracket can be adjusted. In this way, a control knob can be used to adjust the volume of audio output devices such as headphones and speakers or adjust the light effect of the light source assembly, thereby avoiding the need to operate control buttons on different devices or interfaces separately, thereby simplifying the operation process, which can not only improve the operating efficiency, but also improve the operating convenience to enhance the user experience.

[0103] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
