DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1-Figure 4 As shown, the present invention discloses an adjustable audio floor stand, comprising a base 10, an audio bottom plate 60, a rotating mechanism, a lifting mechanism and a tilting mechanism.

[0031] A plurality of universal wheels 11 are provided on the lower side of the base 10, so that the whole audio floor stand can be moved easily. The universal wheels 11 are provided with side brakes, so as to facilitate the fixing of the audio floor stand. The universal wheels can be silent casters.

[0032] The speaker base plate 60 is used to carry the speakers. The speakers are placed on the speaker base plate 60. As the speaker base plate 60 moves, such as lifting, rotating and tilting, the speakers will also lift, rotate and tilt.

[0033] The base 10 is provided with a rotating mechanism, a lifting mechanism and a tilting mechanism. The rotating mechanism drives the bottom plate 60 of the speaker to rotate around the central axis of the base 10. In this way, the rotation of the bottom plate 60 of the speaker can be realized. The lifting mechanism drives the bottom plate 60 of the speaker to rise and fall in the vertical direction, so that it is convenient to drive the speaker to rise and fall in the vertical direction. The tilting mechanism drives the bottom plate 60 of the speaker to tilt to adjust the tilt angle, so that it is convenient to adjust the tilt angle of the speaker.

[0034] Specifically, the rotating mechanism may be an electric turntable 20 .

[0035] The lifting mechanism is arranged on the upper side of the rotating mechanism, and the lifting mechanism includes a lifting drive assembly, a first mounting plate 30, a limiting assembly and a second mounting plate 40. The first mounting plate 30 is fixedly arranged at the moving end of the rotating mechanism, such as fixed on the electric turntable 20. The lifting drive assembly drives the second mounting plate 40 to move in the vertical direction, and the limiting assembly is located between the first mounting plate 30 and the second mounting plate 40 to limit the vertical movement of the second mounting plate 40.

[0036] The lifting drive component may be a first electric push rod 32 .

[0037] The limiting assembly includes a first side plate 31 and a second side plate 33. The first side plate 31 has a plurality of first side plates 31, and the plurality of first side plates 31 are fixedly arranged around the first mounting plate 30. The second side plate 33 has a plurality of second side plates 33, and the plurality of second side plates 33 are fixedly arranged around the second mounting plate 40. The first side plate 31 is arranged parallel to the second side plate 33, and the second side plate 33 is located on the inner side of the first side plate 31. Figure 3-Figure 4 As shown, there are four first side panels 31, which are surrounded by the four first side panels 31 to form a first hollow square column structure, and there are four second side panels 33, which are surrounded by the four second side panels 33 to form a second hollow square column structure. In this way, the structure is more stable.

[0038] The first slide rail 35 and the first slider 34 are arranged between the first side plate 31 and the second side plate 33. The first slider 34 is arranged on the outer wall surface of the second side plate 33, and the first slide rail 35 is arranged on the inner wall surface of the first side plate 31. The first slide rail 35 and the first slider 34 are arranged in cooperation. In this way, by the arrangement of the first slider 34 and the first slide rail 35, the second mounting plate 40, the third mounting plate 50 and the second side plate 33 can be raised and lowered synchronously, and the structure is more stable.

[0039] Reference Figure 4As shown, the tilting mechanism includes a tilting drive component and a third mounting plate 50. The tilting drive component is arranged on the second mounting plate 40. The third mounting plate 50 is fixedly arranged with the second side plate 33. The third mounting plate 50 is located on the upper side of the second mounting plate 40. A through hole 51 is opened on the third mounting plate 50. The sound base plate 60 is hinged to the third mounting plate 50. The tilting drive component passes through the through hole 51 to lift the sound base plate 60. The tilting drive component is a second electric push rod 41. The sound base plate 60 and the third mounting plate 50 are connected by a hinge 52. The third mounting plate 50 is arranged horizontally, which can limit the tilting action of the sound base plate 60. Since the sound base plate 60 is hinged to the third mounting plate 50, such as being connected by a hinge 52, the rod body of the second electric push rod 41 extends through the through hole 51 and abuts against the lower surface of the sound base plate 60, so that the tilting of the sound base plate 60 can be achieved. In this way, the inclination angle of the sound on the sound base plate 60 can be adjusted. Of course, a second slider 42 may be provided on the top of the second electric push rod 41, and a second slide rail 43 may be provided on the audio base plate 60. The second slide rail 43 and the second slider 42 may be provided in cooperation with each other. The second slider 42 and the second slide rail 43 may enable the audio base plate 60 to tilt more stably.

[0040] The present invention also includes a first controller, a second controller and a third controller. The first controller controls the action of the rotating mechanism, the second controller controls the action of the lifting mechanism, and the third controller controls the action of the tilting mechanism. The present invention can be provided with a remote controller, and the remote controller is connected to the first controller, the second controller and the third controller via wireless or Bluetooth signals, so that the flipping, lifting and tilting angle adjustment of the audio floor stand can be realized, and the control is convenient. The present invention uses an electric control adjustment device, and one person can complete the adjustment of the height, tilt angle and axial angle of the speaker, and this process does not require leaving the listening position, which highlights the intuitiveness and speed of the design.
