Technical Field

[0001] This utility model relates to the field of audio auxiliary equipment technology, specifically to a portable base for audio equipment. Background Technology

[0002] As audio playback devices, speakers are widely used in various scenarios such as home entertainment, stage performances, and conference presentations. To facilitate the relocation of speakers, portable stands have become a common auxiliary device.

[0003] Among the existing technical solutions, the publication number CN208849953U discloses a base for speakers that is easy to move and disassemble, including a main body and a pull rod pivot. The main body has load-bearing supports fixed on both the upper left and right sides, and a knob is installed on the left side of the load-bearing support. The knob has a pivot nested inside it. A mounting plate is placed on the inner side of the load-bearing support, and a base is fixed below the mounting plate. A storage chamber is provided above the base.

[0004] The existing technology of assembling and connecting speakers with mobile bases makes the speakers prone to lateral shifting or tipping over during movement, resulting in insufficient safety. Utility Model Content

[0005] The purpose of this invention is to provide a portable base for audio equipment to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A portable speaker stand includes a portable stand body, with casters fixedly installed at both ends of the bottom of the portable stand body, an inner cylinder fixedly installed at the top of the portable stand body, a base plate fixedly installed inside the inner cylinder, and a bottom support plate movably installed inside the base plate.

[0008] Also includes:

[0009] A clamping mechanism is disposed on the surface of the substrate and is used to limit and clamp the speaker body for stable movement and transportation.

[0010] A buffer mechanism is provided inside the base plate to cushion and protect the bottom of the speaker body.

[0011] A further improvement of the present invention is that the clamping mechanism includes a clamping plate, a slider is fixedly connected to the bottom of the clamping plate, a movable rod is fixedly connected to the bottom of the slider, and the bottom of the movable rod is movably installed inside the substrate.

[0012] A further improvement of the present invention is that a drive motor is fixedly installed on one side inside the substrate, a drive gear is fixedly connected to the top of the drive motor, and a rotating block is meshed on the outer side of the drive gear.

[0013] A further improvement of this utility model is that: the surface of the rotating block is provided with an arc-shaped groove, and the inside of the arc-shaped groove is movably sleeved on the outside of the movable rod.

[0014] A further improvement of this utility model is that a connecting base is fixedly installed at the bottom of the base plate, and a hydraulic telescopic rod is fixedly connected to the bottom of the connecting base.

[0015] A further improvement of the present invention is that the buffer mechanism includes a base plate, a buffer column is fixedly installed inside the base plate, an auxiliary plate is fixedly connected to the top of the buffer column, and telescopic rods are fixedly installed at both ends of the bottom of the auxiliary plate.

[0016] A further improvement of this utility model is that an installation groove is provided on the outer side of the bottom of the auxiliary plate, and a rubber gasket is fixedly installed inside the installation groove.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a movable base for an audio device. After the audio device is placed on the base plate, the drive motor is started, which drives the fixed drive gear at the top to rotate synchronously. Since the drive gear meshes with the outer side of the rotating block, the rotating block rotates around its own axis as the drive gear rotates. When the rotating block rotates, the trajectory of the arc groove changes, generating a lateral thrust on the movable rod. The movable rod drives the top slider to slide along the preset track on the surface of the base plate, so that the outer clamping plate moves closer to the audio device until it is tightly attached to the side wall of the audio device, thus completing the clamping and positioning, and firmly confining the audio device within the preset area of ​​the base plate.

[0019] 2. This utility model provides a mobile base for an audio system. The auxiliary plate directly supports the weight of the audio system. The rubber gasket in the mounting groove on the bottom outer side of the auxiliary plate contacts the surface of the base plate. When vibration occurs, the rubber gasket first undergoes elastic deformation. Utilizing the high damping characteristics of the rubber material, it initially absorbs and consumes some of the vertical vibration energy, weakening the transmission intensity of the vibration. The telescopic rod at the bottom of the auxiliary plate and the buffer column form a cooperative support. The telescopic rod precisely extends and retracts along the axial direction during the buffering process, providing a stable guiding effect for the auxiliary plate and effectively preventing it from shifting laterally, tilting, or swaying due to vibration.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-5 As shown, this utility model provides a portable base for an audio device, including a portable base body 1, with two movable wheels 2 fixedly installed at the bottom ends of the portable base body 1, an inner cylinder 3 fixedly installed at the top of the portable base body 1, a base plate 4 fixedly installed inside the inner cylinder 3, and a bottom support plate 5 movably installed inside the base plate 4.

[0029] Also includes:

[0030] A clamping mechanism is provided on the surface of the substrate 4 to limit and clamp the speaker body for stable movement and transportation.

[0031] A buffer mechanism is located inside the base plate 5 to cushion and protect the bottom of the speaker body.

[0032] like Figure 1As shown, after the speaker body is placed on the base plate 5, the clamping mechanism can clamp and move through the transmission mechanism. At the same time, the side clamps form a symmetrical clamping force, fixing the speaker in the central area of ​​the base plate 4, ensuring that it remains relatively stable during movement and avoiding collisions with the base or external objects. When the speaker needs to be moved, the operator can push the moving base body 1 and move it through the moving wheels 2. When the moving wheels 2 roll on uneven ground, they will transmit the vibration to the moving base body 1, and then to the inner cylinder 3, the base plate 4, and finally act on the speaker body on the base plate 5. The buffer mechanism inside the base plate 5 will compress or deform the elastic component when the vibration generates a vertical impact force, converting the rigid impact force into elastic potential energy. Through its own rebound and damping effect, the vibration energy is consumed, allowing the speaker to return to its original position smoothly, thereby reducing the damage of vibration to the bottom of the speaker.

[0033] Example 2

[0034] The difference from Embodiment 1 is that this embodiment discloses a clamping plate 6 and a base plate 53. The clamping mechanism includes the clamping plate 6, a slider 7 is fixedly connected to the bottom of the clamping plate 6, a movable rod 73 is fixedly connected to the bottom of the slider 7, the bottom of the movable rod 73 is movably installed inside the base plate 4, a drive motor 75 is fixedly installed on one side inside the base plate 4, a drive gear 74 is fixedly connected to the top of the drive motor 75, a rotating block 71 is meshed on the outside of the drive gear 74, an arc-shaped groove 72 is formed on the surface of the rotating block 71, the inside of the arc-shaped groove 72 is movably sleeved on the outside of the movable rod 73, and the buffer mechanism includes the base plate 53. A buffer column 531 is fixedly installed inside the base plate 53, an auxiliary plate 533 is fixedly connected to the top of the buffer column 531, telescopic rods 532 are fixedly installed at both ends of the bottom of the auxiliary plate 533, an installation groove 534 is formed on the outside of the bottom of the auxiliary plate 533, and a rubber gasket 535 is fixedly installed inside the installation groove 534.

[0035] like Figure 2 , 4As shown in Figure 5, after placing the speaker body on the base plate 5, start the drive motor 75. The motor output shaft drives the drive gear 74 fixed at the top to rotate synchronously. Since the drive gear 74 meshes with the outer side of the rotating block 71, the rotating block 71 rotates around its own axis as the drive gear 74 rotates. When the rotating block 71 rotates, the trajectory of the arc-shaped groove 72 changes, generating a lateral thrust on the movable rod 73. The movable rod 73 drives the top slider 7 to slide along a preset track on the surface of the base plate 4, thereby driving the clamping plate 6, which is fixedly connected to the slider 7, to move synchronously. This causes the outer clamping plate 6 to move closer to the speaker body until it is tightly fitted against the side wall of the speaker, completing the clamping and positioning. When the moving wheel 2 rolls on an uneven surface, the vibration is transmitted sequentially to the moving base body 1, the inner cylinder 3, and the base plate 4, and finally acts on the base plate 53 in the support plate 5. The vibration is then transmitted to the speaker body on the auxiliary plate 533 through the buffer assembly. The auxiliary plate 533 directly bears the weight of the speaker body, and the rubber gasket 535 in the mounting groove 534 on its bottom side contacts the surface of the base plate 53. When vibration occurs, the rubber gasket 535 first undergoes elastic deformation. Utilizing the high damping characteristics of the rubber material, it initially absorbs and consumes some of the vertical vibration energy, weakening the transmission intensity of the vibration. The telescopic rods 532 at both ends of the bottom of the auxiliary plate 533 and the buffer column 531 in the center form a cooperative support structure. When the speaker is subjected to a large vibration and impact, the auxiliary plate 533 is pressed downward, and the buffer column 531 is further compressed, converting the rigid impact force into elastic potential energy; at the same time, the telescopic rod 532 extends and retracts along the axis, playing a guiding and limiting role, preventing the auxiliary plate 533 from shifting or tilting laterally during the buffering process, thus achieving the function of buffer protection.

[0036] Example 3

[0037] The difference from Embodiment 2 is that this embodiment discloses a base plate 5 and a hydraulic telescopic rod 52. A connecting base 51 is fixedly installed on the bottom of the base plate 5, and a hydraulic telescopic rod 52 is fixedly connected to the bottom of the connecting base 51.

[0038] like Figure 3 As shown, when it is necessary to raise the speaker body to adapt to the usage scenario, the rodless chamber of the hydraulic telescopic rod 52 is activated, pushing the piston rod upward. The piston rod drives the base plate 5 to rise synchronously through the connecting base 51. The buffer mechanism above the base plate 5, the speaker body, and the clamping mechanism on the base plate 4 rise together with the base plate 5 until the preset height is reached.

[0039] The working principle of the speaker's portable base will be explained in detail below.

[0040] like Figure 1-5As shown, after placing the speaker body on the base plate 5, the drive motor 75 is started, and the motor output shaft drives the top-fixed drive gear 74 to rotate synchronously. Since the drive gear 74 meshes with the outer side of the rotating block 71, the rotating block 71 rotates around its own axis as the drive gear 74 rotates. When the rotating block 71 rotates, the trajectory of the arc-shaped groove 72 changes, generating a lateral thrust on the movable rod 73. The movable rod 73 drives the top slider 7 to slide along the preset track on the surface of the base plate 4, thereby driving the clamping plate 6 fixedly connected to the slider 7 to move synchronously, so that the outer clamping plate 6 moves closer to the speaker body until it is tightly fitted with the side wall of the speaker, completing the clamping and positioning. In addition, the auxiliary plate 533 directly bears the weight of the speaker body, and the rubber gasket 535 in the bottom outer mounting groove 534 contacts the surface of the base plate 53. When vibration occurs, the rubber gasket 535 first undergoes elastic deformation, utilizing the high damping characteristics of the rubber material to initially absorb and dissipate some of the vertical vibration energy, weakening the transmission intensity of the vibration. The telescopic rods 532 at both ends of the bottom of the auxiliary plate 533 and the central buffer column 531 form a cooperative support structure. When the speaker is subjected to a large vibration impact force, the auxiliary plate 533 is pressed downward, and the buffer column 531 is further compressed, converting the rigid impact force into elastic potential energy. At the same time, the telescopic rods 532 extend and retract axially, playing a guiding and limiting role, preventing the auxiliary plate 533 from shifting laterally or tilting during the buffering process, thus achieving the function of buffer protection.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
