Description

Technical Field

[0001] The invention relates to the technical field of vocal performance, in particular to a vocal performance auxiliary device. Background Art

[0002] Vocal music is mainly based on human vocal cords, which cooperate with the mouth, tongue and nasal cavity to act on the breath to produce pleasant, continuous and rhythmic sounds. When the performer is performing vocal music, a stand for placing music scores will be used to assist the performer in performing vocal music.

[0003] When using existing vocal performance auxiliary devices, since the performers often make certain body movements during the vocal performance and the vocal performance auxiliary devices have poor stability, it is easy for the performers to touch the vocal performance auxiliary devices during the performance, which makes the vocal performance auxiliary devices easy to move or tilt and collapse, thereby affecting the performer's performance process and the audience's viewing effect.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing vocal performance auxiliary devices on the market, and even if they can be solved, they need to be solved through external tools, which makes it impossible to achieve the desired effect.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Example 1: Please refer to Figures 1-8, the present invention provides a technical solution: a vocal performance assistance device, including a main body mechanism 1. The main body mechanism 1 includes a bracket 11, which is composed of an inner cylinder and an outer cylinder, and the inner cylinder and the outer cylinder are fixed by nuts, so that the inner cylinder can slide inside the outer cylinder, thereby enabling the height of the bracket 11 to be adjusted. A placement table 12 is fixedly installed at the top of the bracket 11, and a tripod 13 is arranged on the outer surface of the bracket 11. A fixing mechanism 2 is arranged below the tripod 13. The tripod 13 is divided into upper and lower parts. The upper part consists of a movable frame and a support column movably hinged inside the frame. The upper part can slide on the outer surface of the bracket 11. The lower part consists of connecting rods, and the lower part is movably hinged to the bracket 11, and the upper and lower parts are movably hinged to each other;

[0040] The fixing mechanism 2 includes a load-bearing unit 21, which is located inside the tripod 13. The load-bearing unit 21 is used to increase the gravity at the bottom of the bracket 11 to prevent the bracket 11 from moving and tilting.

[0041] As a further limitation of the load-bearing unit 21 of the present invention, the load-bearing unit 21 includes a load-bearing box 2101 made of a metal material, so that it has a certain weight. The load-bearing box 2101 is located below the tripod 13. The bracket 11 is clamped inside the load-bearing box 2101. A rack plate 2102 is fixedly installed on the outer surface of the bracket 11. The rack plate 2102 is clamped inside the load-bearing box 2101. A channel for the rack plate 2102 to pass through is opened on the upper surface of the load-bearing box 2101. A bidirectional ball screw 2103 is rotatably connected inside the load-bearing box 2101. Two threads in opposite directions are provided on the outer surface of the bidirectional ball screw 2103. A connecting gear 2104 is fixedly installed on the outer surface of the bidirectional ball screw 2103. The left side surface of the rack plate 2102 meshes with the outer surface of the connecting gear 2104. Two moving plates 2105 are threadedly connected to the outer surface of the bidirectional ball screw 2103. Clamping frames 2106 are fixedly installed on the side surfaces of the two moving plates 2105 close to each other. The inner walls of the two clamping frames 2106 are in contact with the outer surface of the bracket 11. One end of the bidirectional ball screw 2103 penetrates through the load-bearing box 2101 and is fixedly installed with a rotating disk 2107. A connecting box 2108 is fixedly installed on the front surface of the load-bearing box 2101. Two first electromagnets 2109 are fixedly installed on the inner wall of the connecting box 2108. Two groups of connecting springs 2110 are fixedly installed on the inner wall of the connecting box 2108. The number of each group of connecting springs 2110 is two. One end of each group of connecting springs 2110 away from the first electromagnet 2109 is fixedly installed with a second electromagnet 2111. Brake pads 2112 are fixedly installed on the side surfaces of the two second electromagnets 2111 close to each other. The polarities of the side surfaces of the first electromagnet 2109 and the second electromagnet 2111 close to each other are the same. Thus, the repulsive force between the two is utilized to make the brake pads 2112 contact the rotating disk 2107. Then, the friction force between the brake pads 2112 and the rotating disk 2107 is utilized to lock the rotating disk 2107. The side surfaces of the two brake pads 2112 close to each other are respectively in contact with the front and back surfaces of the rotating disk 2107. Connecting frames 2113 are fixedly installed on the side surfaces of the two moving plates 2105 away from each other. Four fixing springs 2114 are fixedly installed on the inner wall of the load-bearing box 2101. One end of each fixing spring 2114 away from the load-bearing box 2101 is fixedly installed with a moving block 2115. The outer surface of each moving block 2115 is slidably connected to the outer surface of the connecting frame 2113. Two groups of compression springs 2116 are fixedly installed on the inner wall of the load-bearing box 2101. The number of each group of compression springs 2116 is two. One end of each group of compression springs 2116 away from the load-bearing box 2101 is fixedly installed with a connecting block 2117. When the moving plates 2105 approach each other, the moving plates 2105 drive the connecting frames 2113 to push the moving blocks 2115 to move towards the side surfaces away from each other, and at the same time compress the fixing springs 2114, so that the corresponding two moving blocks 2115 are separated from each other.Thus, the blocking of the connecting block 2117 is released, and then under the action of the elastic force of the compression spring 2116, the connecting block 2117 is clamped inside the bracket 11. The compression spring 2116 is always in a compressed state, and the connecting block 2117 is clamped inside the bracket 11. On the side surfaces of the two connecting blocks 2117 that are far away from each other, pull rods 2118 are fixedly installed. The ends of the two pull rods 2118 that are far away from each other penetrate to the outside of the load-bearing box 2101. By providing a load-bearing unit 21, using the gravity of the load-bearing box 2101, the bracket 11 is fixed inside the load-bearing box 2101, thereby increasing the gravity at the bottom of the bracket 11, shifting the center of gravity of the entire bracket 11 downward, and further preventing the phenomenon that the bracket 11 moves or tilts and collapses when the performer touches the bracket 11.,

[0042] Please refer to Figure 3 , a sliding rod 2119 is fixedly installed on the inner wall of the load-bearing box 2101. The outer surface of the sliding rod 2119 is slidably connected to the inner walls of the two moving plates 2105. The installation of the sliding rod 2119 plays a role in restricting the moving trajectory of the moving plate 2105, thereby preventing the phenomenon that the moving plate 2105 rotates during movement, and further ensuring the stability of the movement of the moving plate 2105.

[0043] Please refer to Figure 4 , four telescopic rods 2120 are fixedly installed on the inner wall of the connecting box 2108. The four telescopic rods 2120 are respectively located inside the four connecting springs 2110. The telescopic ends of each telescopic rod 2120 are fixedly connected to the outer surface of the second electromagnet 2111. The installation of the telescopic rod 2120 plays a role in restricting the moving trajectory of the second electromagnet 2111, thereby preventing the phenomenon that the second electromagnet 2111 deviates from the moving trajectory during movement, and further ensuring the stability of the movement of the second electromagnet 2111.

[0044] Please refer to Figure 3 and Figures 5-6 , four telescopic columns 2121 are fixedly installed on the inner wall of the load-bearing box 2101. The four telescopic columns 2121 are respectively located inside the four fixing springs 2114. The telescopic ends of the four fixing springs 2114 are respectively fixedly connected to the outer surfaces of the four moving blocks 2115. The installation of the telescopic column 2121 plays a role in restricting the moving trajectory of the moving block 2115, thereby ensuring the stability of the movement of the moving block 2115.

[0045] Please refer to Figure 5 and Figure 7, the bottom surfaces of the two connecting blocks 2117 are fixedly installed with sliders 2122. The inner bottom wall of the load-bearing box 2101 is provided with two sliding grooves 2123. The two sliders 2122 are respectively slidably connected inside the two sliding grooves 2123. The installation of the sliders 2122 and the sliding grooves 2123 restricts the movement trajectory of the connecting block 2117, thus ensuring the stability of the movement of the connecting block 2117.

[0046] The specific implementation manner of this embodiment is as follows: When in use, the performer first places the load-bearing box 2101 on the ground. Then, the performer inserts the support 11 into the load-bearing box 2101, and at the same time inserts the rack plate 2102 into the load-bearing box 2101. Then, by moving the rack plate 2102, the connecting gear 2104 is driven to rotate, so that the connecting gear 2104 drives the bidirectional ball screw 2103 to rotate. Furthermore, the bidirectional ball screw 2103 drives the two moving plates 2105 to move towards the side close to each other, so that the two moving plates 2105 drive the two clamping frames 2106 to move towards the side close to each other, enabling the clamping frames 2106 to clamp and limit the support 11. During the movement of the moving plate 2105, the moving plate 2105 drives the connecting frame 2113 to move, so that the connecting frame 2113 pushes the moving block 2115, causing the corresponding two moving blocks 2115 to separate from each other. When the bottom end of the support 11 contacts the inner bottom wall of the load-bearing box 2101, the space where the corresponding two moving blocks 2115 separate just allows the connecting block 2117 to move, so that the connecting block 2117 moves towards the side close to the support 11 under the action of the elastic force of the compression spring 2116, so that the connecting block 2117 is inserted into the support 11, further limiting and fixing the support 11. Then, the performer turns on the first electromagnet 2109 and the second electromagnet 2111 through an external remote control device, and uses the repulsive force between the two to drive the brake pad 2112 to move towards the side close to the rotating disc 2107. Using the frictional force between the brake pad 2112 and the rotating disc 2107, the brake pad 2112 locks the rotating disc 2107, so that the center of gravity of the support 11 moves downwards, avoiding the phenomenon that the support 11 moves or collapses during the performance of the performer.

[0047] Embodiment 2: Please refer to Figure 1 , Figure 5 and Figures 8-10 , the present invention provides a technical solution: a vocal performance auxiliary device. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The fixing mechanism 2 further includes an adsorption unit 22. The adsorption unit 22 is located inside the tripod 13. The load-bearing unit 21 is used in cooperation with the adsorption unit 22. The adsorption unit 22 is used to adsorb and fix the support 11 on the ground.

[0048] As a further limitation of the adsorption unit 22 of the present invention, the adsorption unit 22 includes a suction cup 2201. The upper surface of the suction cup 2201 is fixedly connected to the bottom surface of the load-bearing box 2101. A first connecting wheel 2202 is fixedly installed on the outer surface of the bidirectional ball screw 2103. A bearing seat 2203 is fixedly installed on the inner bottom wall of the load-bearing box 2101. A rotating shaft 2204 is rotatably connected inside the bearing seat 2203. A second connecting wheel 2205 is fixedly installed at one end of the rotating shaft 2204. A belt 2206 is jointly sleeved on the outer surfaces of the first connecting wheel 2202 and the second connecting wheel 2205. The first connecting wheel 2202 and the second connecting wheel 2205 are drivingly connected through the belt 2206. A rotating disk 2207 is fixedly installed at the other end of the rotating shaft 2204. By the rotation of the bidirectional ball screw 2103, cooperating with the first connecting wheel 2202, the belt 2206 and the second connecting wheel 2205, the rotating shaft 2204 is driven to rotate, thereby driving the rotating disk 2207 to rotate. A connecting column 2208 is fixedly installed on the back surface of the rotating disk 2207. A fixing block 2209 is fixedly installed on the inner bottom wall of the load-bearing box 2101. A toothed disk 2210 is rotatably connected to the back surface of the fixing block 2209. The inner wall of the toothed disk 2210 is slidably connected to the outer surface of the connecting column 2208. A toothed column 2211 is meshingly connected to the outer surface of the toothed disk 2210. A pressing frame 2212 is fixedly installed on the outer surface of the toothed column 2211. An inflatable block 2213 is fixedly installed on the inner bottom wall of the load-bearing box 2101. The inflatable block 2213 is made of rubber material. The upper surface of the inflatable block 2213 is in contact with the bottom surface of the pressing frame 2212. Connecting pipes 2214 are fixedly communicated with both side surfaces of the inflatable block 2213. Check valves 2215 are fixedly communicated with the outer surfaces of the two connecting pipes 2214. The intake directions of the two check valves 2215 are the same. Two fixing boxes 2216 are fixedly installed on the inner bottom wall of the load-bearing box 2101. One ends of the two connecting pipes 2214 away from the inflatable block 2213 respectively penetrate into the interiors of the two fixing boxes 2216. Electric push rods 2217 are fixedly installed on the inner bottom walls of the two fixing boxes 2216. Sealing blocks 2218 are fixedly installed at the telescopic ends of the two electric push rods 2217. The outer surfaces of the two sealing blocks 2218 are slidably connected to the inner walls of the two fixing boxes 2216 respectively. During the adjustment process, the two sealing blocks 2218 are respectively located on both sides of the two connecting pipes 2214, thereby playing a role in changing the intake and outlet directions. Delivery pipes 2219 are fixedly communicated with the front and back surfaces of the two fixing boxes 2216. Among them, two delivery pipes 2219 penetrate into the interior of the suction cup 2201, and the other two delivery pipes 2219 penetrate outside the load-bearing box 2101. By providing the adsorption unit 22, by bringing the suction cup 2201 into contact with the ground, and then discharging the gas between the suction cup 2201 and the ground, the load-bearing box 2101 is adsorbed and fixed on the ground, thereby assisting the load-bearing unit 21 to further fix the bracket 11.Further, the phenomenon that the bracket 11 moves, tilts or collapses under the touch of an external object is avoided.

[0049] Please refer to Figure 9 , two limit blocks 2220 are fixedly installed on the back surface of the fixed block 2209, and the inner walls of the two limit blocks 2220 are both slidably connected to the outer surface of the tooth column 2211. The installation of the limit block 2220 plays a role in restricting the movement track of the tooth column 2211, thereby avoiding the phenomenon that the tooth column 2211 deviates from the movement track during movement, and further ensuring the stability of the movement of the tooth column 2211.

[0050] The specific implementation of this embodiment is as follows: during the rotation of the bidirectional ball screw 2103, the bidirectional ball screw 2103 drives the first connecting wheel 2202 to rotate, so that the first connecting wheel 2202 drives the second connecting wheel 2205 to rotate through the belt 2206, and then the second connecting wheel 2205 drives the rotating shaft 2204 and the rotating disk 2207 to rotate, so that the rotating disk 2207 drives the connecting column 2208 to rotate, and during the rotation of the connecting column 2208, the connecting column 2208 drives the toothed plate 2210 to swing, so that under the restriction of the limit block 2220, the toothed plate 2210 drives the tooth column 2211 to move up and down reciprocatingly, so that the tooth column 2211 drives the pressing frame 2212 to move up and down reciprocatingly, so that the pressing frame 2212 presses the inflatable block 2213. Under the action of the one-way valve 2215, the one-way valve 2215 here allows the gas to flow only to one side, so that the gas can only flow from the right side of the inflatable block 2213 to the left side, so that the air between the suction cup 2201 and the ground enters the interior of the fixed box 2216 through the conveying pipe 2219. When the inflatable block 2213 expands upward, the gas between the suction cup 2201 and the ground passes through the conveying pipe 2219. When the inflatable block 2213 is pressed, the gas inside the inflatable block 2213 passes through the connecting tube 2214 on the left and is discharged to the outside, so that the suction cup 2201 is adsorbed on the ground, further preventing the bracket 11 from moving or tilting and collapsing. When the performer needs to separate the suction cup 2201 from the ground, the performer opens the two electric push rods 2217 and uses the power provided by the electric push rods 2217 to move the two sealing blocks 2218 to the other side of the connecting tube 2214, thereby changing the inflatable block 2213. The air inlet and outlet positions make the right side of the inflatable block 2213 connected to the outside world, and the left side of the inflatable block 2213 connected to the internal space of the suction cup 2201. When the inflatable block 2213 inhales air, under the action of atmospheric pressure, the external gas enters the interior of the inflatable block 2213 through the right connecting pipe 2214. When the inflatable block 2213 exhausts air, the gas inside the inflatable block 2213 enters the interior of the suction cup 2201 through the left connecting pipe 2214, thereby allowing the external air to enter the interior of the suction cup 2201 after passing through the delivery pipe 2219, which makes it convenient for the performer to separate the suction cup 2201 from the ground.

The electric cylinder 309 is movably hinged inside the concave frame 306. The outer surface of the linear driver 307 is fixedly installed with a fixing seat 310. The telescopic end of the electric cylinder 309 is movably hinged with the fixing seat 310. The power provided by the electric cylinder 309 is used to drive the linear driver 307 to adjust the angle, so as to adjust the angle of the linear driver 307 according to the tilt angle, so as to facilitate the support of the bracket 11. A level 311 is fixedly installed on the bottom surface of the placement table 12. By providing a straightening mechanism 3, the level 311 is used to detect the horizontality of the placement table 12. When the placement table 12 tilts, the position of the rubber head 308 is adjusted, so that the linear driver 307 cooperates with the rubber head 308 to support the tilted bracket 11, and further avoids the tilt and collapse of the bracket 11.

[0053] See also Figure 1 and Figures 13-14, two linear push rods 312 are fixedly installed on both side surfaces of the load-bearing box 2101. A universal wheel 313 is fixedly installed at the telescopic end of each linear push rod 312. The power provided by the linear push rod 312 is used to drive the universal wheel 313 to move downward, so that the universal wheel 313 contacts the ground and lifts the load-bearing box 2101, thereby facilitating the performer to move the load-bearing box 2101. A fixing frame 314 is fixedly installed on the bottom surface of the placing table 12. A worm 315 and a rotating rod 316 are respectively rotatably connected inside the fixing frame 314.

The mutually approaching side surfaces of the two tooth plates 319 are both meshed with the outer surface of the fixed gear 318. The mutually remote side surfaces of the two tooth plates 319 are respectively fixedly connected to the inner walls of the two clamping plates 320. By rotating the worm 315, the worm 315 drives the worm gear 317, the rotating rod 316 and the fixed gear 318 to rotate, so that the fixed gear 318 drives the two tooth plates 319 and the two clamping plates 320 to move towards the mutually approaching side surfaces, thereby achieving the purpose of clamping and fixing the equipment for vocal music performance recording and facilitating taking pictures and videos of the vocal music performance process.

[0054] The specific implementation manner of this embodiment is as follows: During the vocal music performance, the spirit level 311 is used to detect the tilt angle of the placement table 12 in real time. When the spirit level 311 detects that the placement table 12 is tilted, since the fixed disk 301 is fixedly connected to the support 11, the rack ring 303 is fixedly installed on the fixed disk 301 through the connecting bearing 302, and the rotation motor 304 is fixed on the fixed disk 301. When the rack ring 303 is tilted, the rotation gear 305 is also tilted, so that they remain relatively stationary. Therefore, the rotation gear 305 always meshes with the rack ring 303. The power provided by the rotation motor 304 is used to drive the rotation gear 305 to rotate, so that the rotation gear 305 drives the rack ring 303 to rotate, and then the rack ring 303 drives the concave frame 306 to rotate, so that the position of the concave frame 306 is consistent with the tilt direction of the support 11. At the same time, the power provided by the electric cylinder 309 is used to drive the fixed seat 310 to move, so that the fixed seat 310 drives the linear actuator 307 to adjust the angle. At the same time, the power provided by the linear actuator 307 is used to drive the rubber head 308 to move downward, so that the rubber head 308 contacts the ground, thereby supporting the support 11. Then, the linear actuator 307 continues to extend, so as to straighten the support 11, avoid the phenomenon of the support 11 collapsing, and thus ensure the vocal music performance of the performer. Before the vocal music performance, the performer places the video recording device between the two clamping plates 320. Then, the performer rotates the worm 315, so that the worm 315 drives the worm gear 317 to rotate, so that the worm gear 317 drives the rotating rod 316 to rotate, and then the rotating rod 316 drives the fixed gear 318 to rotate, so that the fixed gear 318 drives the two toothed plates 319 engaged with it to move towards the side close to each other. At the same time, the toothed plates 319 drive the two clamping plates 320 to move towards the side close to each other, so as to clamp and fix the video recording device, facilitating the shooting and recording of the performer's vocal music performance.
