Description

Technical Field

[0001] This invention relates to the field of audio technology, and more particularly to a wireless magnetic levitation lifting platform for stage audio equipment. Background Technology

[0002] Stage audio equipment is an indispensable component of modern stage performances, primarily used for sound reinforcement, mixing, effects processing, and sound transmission. Common stage audio equipment includes mixing consoles, power amplifiers, speakers, microphones, and effects processors.

[0003] Stage sound systems are typically installed high up on the stage. Multiple sound systems are first assembled, then lifted using hoisting equipment and bolted to one side of the stage's steel frame. After installation, the speakers are interconnected via audio cables. Because current stage sound systems are installed at a high position, manual assembly on the ground is required before the entire system is lifted to its installation location and bolted in. This process makes the sound systems susceptible to impacts during hoisting, affecting their lifespan. To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0004] The purpose of this invention is to: drive the transmission shaft to rotate after the drive motor is started, thereby driving the second helical gear that is inserted with it. Through gear meshing, the first helical gear rotates accordingly, driving the fixedly connected slider to rotate on the internal thread of the lead screw. The rotary bearing transmits the motion to the platform support, causing it to rise and fall along the lead screw. Since the assembly plate and stage speakers are fixed to the platform support, the vertical lifting function of the speakers is finally realized, thus overcoming the shortcomings of the existing technology where the stage speakers are installed at a high position, requiring manual assembly on the ground during installation, followed by hoisting the entire stage speaker assembly to the installation position using lifting equipment, and then installation with bolts. This results in the stage speakers being easily bumped and damaged during hoisting, affecting the service life of the speakers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wireless magnetic levitation lifting platform for stage audio equipment, comprising a fixed plate and a limiting column, wherein the limiting column is fixedly installed on the top surface of the fixed plate, a lead screw is installed on the top surface of the fixed plate, a slider is rotatably installed on the outer surface of the lead screw, a first helical gear is fixedly installed on the bottom surface of the slider, a rotary bearing is fixedly installed on the outer surface of the slider, a platform bracket is fixedly installed on the outer surface of the rotary bearing, a slot is opened on the top surface of the platform bracket, a connecting plate is installed on the bottom surface of the platform bracket, and a second helical gear is rotatably installed on the inner wall of the connecting plate; The suspension assembly includes a top plate, which is fixedly installed on the top surface of the limiting post. The top surface of the top plate is provided with a groove, and a suspended speaker housing is movably installed on the inner wall of the groove. A permanent magnet is fixedly installed on the bottom surface of the inner wall of the suspended speaker housing. A suspension base is movably inserted into the top surface of the platform support. An electromagnet is fixedly installed on the bottom surface of the inner wall of the suspension base, and a pin is provided at the bottom of the suspension base.

[0006] Furthermore, there are three limiting posts, which are arranged in a circular array and equidistantly distributed on the top surface of the fixed plate. There are two rotary bearings, which are equidistantly distributed on the outer surface of the slider. Both rotary bearings are fixedly connected to the inner wall of the platform support. The second helical gear meshes with the first helical gear.

[0007] Furthermore, the bottom surface of the suspended speaker housing is in movable contact with the inner wall of the groove, the pins are three in a ring array equidistantly distributed on the bottom surface of the suspended base, the pins are movably inserted into the inner wall of the platform bracket, and the electromagnets are six in a ring array equidistantly distributed on the bottom surface of the inner wall of the suspended base.

[0008] Furthermore, the support mechanism includes a drive assembly and an installation assembly. The drive assembly includes a setting plate, a fixing bolt threadedly connected to one side surface of the setting plate, the setting plate being installed on one side surface between platforms, a plug-in plate provided on one side surface of the setting plate, a slide plate fixedly installed on one side surface of the setting plate, a drive motor slidably connected to the top surface of the slide plate, and a transmission shaft fixedly installed at the output end of the drive motor.

[0009] Furthermore, there are two plug-in plates, which are equidistantly distributed on one side surface of the setting plate. The plug-in plates are movably plugged into the inner wall of the slot. There are two fixing bolts, which are equidistantly distributed on one side surface of the setting plate. The fixing bolts are threadedly rotated to the platform support.

[0010] Furthermore, the slide plates are two equidistantly distributed on one side surface of the setting plate, and the inner walls of both slide plates are slidably connected to the drive motor. The transmission shaft extends from one side surface of the setting plate to the other side surface, and the transmission shaft is movably inserted into the inner wall of the second helical gear.

[0011] Furthermore, the mounting assembly includes an assembly plate mounted on one side surface between the platforms, a stage sound system mounted on one side surface of the assembly plate, and a tripod sleeved on the outer surface of the limiting column.

[0012] Furthermore, the assembly plate is movably inserted into the inner wall of the slot, and there are several tripods, which are arranged in a linear array and equidistantly sleeved on the outer surface of the limiting post.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This wireless magnetic levitation lifting platform for stage audio equipment, after being started by a drive motor, rotates the transmission shaft, which in turn drives the second helical gear that is plugged into it. Through gear meshing, the first helical gear rotates accordingly, driving the fixedly connected slider to rotate on the internal thread of the lead screw. The rotary bearing transmits the motion to the platform support, causing it to rise and fall along the lead screw. Since the assembly plate and stage audio equipment are fixed to the platform support, the vertical lifting function of the audio equipment is ultimately achieved. This overcomes the shortcomings of existing technologies where the stage audio equipment is installed at a high position, requiring manual assembly on the ground before hoisting the entire audio assembly to the installation position and then installing it with bolts. This process makes the stage audio equipment susceptible to damage during hoisting, affecting its lifespan. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] like Figures 1-10 As shown, this invention discloses a wireless magnetic levitation lifting platform for stage sound equipment, comprising a fixed plate 1 and three limiting columns 101. The three limiting columns 101 are arranged in a circular array and equidistantly distributed on the top surface of the fixed plate 1. The limiting columns 101 are fixedly installed on the top surface of the fixed plate 1. A lead screw 102 is installed on the top surface of the fixed plate 1. A slider 103 is rotatably mounted on the outer surface of the lead screw 102. A first helical gear 104 is fixedly installed on the bottom surface of the slider 103. A first helical gear 104 is fixedly installed on the outer surface of the slider 103. There are two rotary bearings 105, both of which are fixedly connected to the inner wall of the platform support 106. The rotary bearings 105 are two equidistantly distributed on the outer surface of the slider 103. The platform support 106 is fixedly installed on the outer surface of the rotary bearings 105. The top surface of the platform support 106 has a slot 107. The bottom surface of the platform support 106 is equipped with a connecting plate 108. The inner wall of the connecting plate 108 is rotatably mounted with a second helical gear 109. The second helical gear 109 meshes with the first helical gear 104.

[0019] In this embodiment of the invention, when the stage sound system 401 needs to be raised or lowered after assembly, the drive motor 304 is activated. When the drive motor 304 is activated, it drives the transmission shaft 305 mounted on its output end to rotate. The transmission shaft 305 is movably inserted into the inner wall of the second helical gear 109. Therefore, when the drive motor 304 drives the transmission shaft 305 to rotate, the second helical gear 109 will drive the first helical gear 104 meshing with it to rotate. The first helical gear 104 is fixedly connected to the slider 103, so the first helical gear 104 rotates. When the slider 103 rotates on the inner wall of the rotating shaft, the slider 103 and the lead screw 102 are connected by a threaded rotation. When the slider 103 rotates, it will drive the platform support 106 to move along the lead screw 102 through the rotary bearing 105. Since the assembly plate 4 and the slide plate 303 are inserted and fixed on the inner wall of the platform support 106, when the platform support 106 moves, the stage speaker 401 fixed on one side of the platform support 106 will move up and down with the platform support 106 through the assembly plate 4, thereby realizing the lifting function of the stage speaker 401.

[0020] like Figures 1-10 As shown, the suspension assembly includes a top plate 2, which is fixedly installed on the top surface of the limiting post 101. A groove 201 is provided on the top surface of the top plate 2. A suspended speaker housing 202 is movably installed on the inner wall of the groove 201. The bottom surface of the suspended speaker housing 202 is in contact with the inner wall of the groove 201. A permanent magnet 203 is fixedly installed on the bottom surface of the inner wall of the suspended speaker housing 202. A suspension base 204 is movably inserted into the top surface of the platform support 106. An electromagnet 205 is fixedly installed on the bottom surface of the inner wall of the suspension base 204. Six electromagnets 205 are evenly distributed in a ring array on the bottom surface of the inner wall of the suspension base 204. A pin 206 is provided at the bottom of the suspension base 204. The pin 206 is movably inserted into the inner wall of the platform support 106. Three pins 206 are evenly distributed in a ring array on the bottom surface of the suspension base 204.

[0021] In this embodiment of the invention, when it is necessary to activate the floating speaker on the top of the top plate 2, the electromagnet 205 is first energized, causing it to generate a magnetic field. When the electromagnet 205 generates a magnetic field, the drive motor 304 is activated again. The drive motor 304 drives the platform support 106 to move upward, and indirectly drives the floating base 204 to move upward. During the upward movement, the floating base 204 will continuously approach the bottom of the floating speaker shell 202. Since the electromagnet 205 is energized and generates a magnetic field, when the floating base 204 approaches the bottom of the floating speaker shell 202, the magnetic field will generate the same magnetic poles with the permanent magnet 203 inside the floating speaker shell 202. The repulsive force between the magnetic poles cancels out the gravity, thus achieving the levitation of the floating speaker.

[0022] The support mechanism includes a drive assembly and a mounting assembly. The drive assembly includes a mounting plate 3. A fixing bolt 301 is threadedly connected to one side surface of the mounting plate 3. The fixing bolt 301 is rotatably threadedly connected to the platform support 106. Two fixing bolts 301 are equidistantly distributed on one side surface of the mounting plate 3. The mounting plate 3 is mounted on one side surface between platforms. Two insertion plates 302 are provided on one side surface of the mounting plate 3. The insertion plates 302 are movably inserted into the inner wall of the slot 107. Two insertion plates 302 are equidistantly distributed. On one side surface of the mounting plate 3, a sliding plate 303 is fixedly installed. The sliding plate 303 consists of two equally spaced sliding plates 303 on one side surface of the mounting plate 3. A drive motor 304 is slidably connected to the top surface of the sliding plate 303. The inner walls of both sliding plates 303 are slidably connected to the drive motor 304. A transmission shaft 305 is fixedly installed at the output end of the drive motor 304. The transmission shaft 305 extends from one side surface of the mounting plate 3 to the other side surface. The transmission shaft 305 is movably inserted into the inner wall of the second helical gear 109.

[0023] The mounting components include a mounting plate 4, which is movably inserted into the inner wall of the slot 107. The mounting plate 4 is installed on one side surface between the platforms. A stage sound system 401 is installed on one side surface of the mounting plate 4. A tripod 402 is sleeved on the outer surface of the limiting post 101. There are several tripods 402, which are arranged in a linear array and equidistantly sleeved on the outer surface of the limiting post 101.

[0024] Specific usage procedure: When using the wireless magnetic levitation lifting platform for stage equipment, first fix the fixing plate 1 to the ground with bolts to provide stability for the fixing plate 1 and the limiting column 101. After fixing, when it is time to install the sound system, lift the entire platform support 106 and align the inner wall of the slider 103 with the top of the lead screw 102. At the same time, align the holes on the surface of the platform support 106 with the three limiting columns 101. When both are aligned, fit the slider 103 and the entire platform support 106 onto the outer surfaces of the limiting columns 101 and the lead screw 102, and manually press the platform to make it move along the lead screw 102. 02. Move downwards. When the platform support 106 moves downwards to a height that can be touched by a person, stop moving the platform support 106. Pick up the setting plate 3 and align the plug plate 302 fixed on one side surface with the slot 107 on the top of the platform support 106. After alignment, press the setting plate 3 downwards, so that the plug plate 302 is inserted into the inner wall of the slot 107. Thus, the setting plate 3 is fixed to one side surface between the platforms by the plug plate 302. After the setting plate 3 is fixed, lift the drive motor 304 so that its base is aligned with the inner wall of the slide plate 303. When the two are aligned, push the drive motor 304. 04. The drive motor 304 moves on the surface of the slide plate 303, causing the transmission shaft 305 mounted on the output end of the drive motor 304 to extend from one side of the mounting plate 3 to the other side. As the drive motor 304 slides continuously, the distance between the transmission shaft 305 and the second helical gear 109 will continuously decrease. At this time, the second helical gear 109 is manually rotated, causing it to rotate on the inner wall of the connecting plate 108. By rotating the second helical gear 109, the internal hole of the second helical gear 109 is aligned with the external angle of the transmission shaft 305. When the two are aligned, the drive motor 304 is pushed again to move on the surface of the slide plate 303. Finally, the drive shaft 305 is inserted into the inner wall of the second helical gear 109 to install the drive device. After installation, the assembly plate 4 is inserted into the slot 107 opened on the top surface of the platform bracket 106. After insertion, the stage sound system 401 that needs to be raised and lowered is installed on one side surface of the assembly plate 4 to complete the assembly of the lifting platform. After assembly, the tripod 402 sleeved on the outer surface of the limiting column 101 is pushed upward and fixed to the outer surface of the limiting column 101 with bolts. The tripod 402 provides support force for the lifting platform composed of the limiting column 101 and provides stability for it.

[0025] When the stage sound system 401 needs to be raised or lowered after assembly, the drive motor 304 is activated. When the drive motor 304 starts, it drives the transmission shaft 305 mounted on its output end to rotate. The transmission shaft 305 is movably inserted into the inner wall of the second helical gear 109. Therefore, when the drive motor 304 drives the transmission shaft 305 to rotate, the second helical gear 109 drives the first helical gear 104, which meshes with it, to rotate. The first helical gear 104 is fixedly connected to the slider 103, so when the first helical gear 104 rotates, it drives... The slider 103 rotates on the inner wall of the rotating shaft. The slider 103 and the lead screw 102 are connected by a threaded rotation. When the slider 103 rotates, it will drive the platform support 106 to move along the lead screw 102 through the rotary bearing 105. Since the assembly plate 4 and the slide plate 303 are inserted and fixed to the inner wall of the platform support 106, when the platform support 106 moves, it will drive the stage sound 401 fixedly installed on one side of the platform support 106 to move up and down with the platform support 106 through the assembly plate 4, thereby realizing the lifting function of the stage sound 401.

[0026] When the floating speaker on the top of the top plate 2 needs to be activated, the electromagnet 205 is first energized, causing it to generate a magnetic field. When the electromagnet 205 generates a magnetic field, the drive motor 304 is activated again. The drive motor 304 drives the platform support 106 to move upward, and indirectly drives the floating base 204 to move upward. During the upward movement, the floating base 204 will continuously approach the bottom of the floating speaker shell 202. Since the electromagnet 205 is energized and generates a magnetic field, when the floating base 204 approaches the bottom of the floating speaker shell 202, the magnetic field will generate the same magnetic poles with the permanent magnet 203 inside the floating speaker shell 202. The repulsive force between the magnetic poles cancels out the gravity, thus achieving the levitation of the floating speaker.

[0027] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
