As people's requirements continue to increase, people yearn for a more colorful life. The audio system is constantly improving and perfecting with people's needs. Among them, wall-mounted audio is one of the types of audio. Wall-mounted audio is loved by people because it can be fixed on the wall, has a beautiful structure and does not take up floor space.

[0003] like Figure 1 The figure shows a common existing wall-mounted audio structure and installation schematic diagram. The existing wall-mounted audio in the figure is mainly composed of an audio body, a hanger, a wall-mounted plate, a rotating plate, and an adjusting bolt.

[0036] The connecting unit 6 installed on the wall-mounted plate 2 is used to quickly install the sound body 1 and the vertical adjustment unit 5. When in use, the assembly between the sound body 1 and the wall-mounted plate 2 can be realized without screws, which reduces the workload of assembling the sound body 1 and allows for faster disassembly when the sound body 1 is repaired;

[0037] An oil tank No. 1 7 is fixed on the top of the lateral adjustment unit 4, and an oil replenishing mechanism No. 1 8 is provided between the oil tank No. 1 7 and the lateral adjustment unit 4. An oil tank No. 2 9 is fixed on one side of the vertical adjustment unit 5, and an oil replenishing mechanism No. 2 10 is provided between the oil tank No. 2 9 and the vertical adjustment unit 5. Lubricating oil can be sprayed on the transmission components at the corresponding positions when adjusting the angle, and all transmission components of the No. 1 drive member 13 and the No. 2 drive member 39 can be oiled and maintained without disassembling the arc shell.

[0038] For further information, see Figure 3 The lateral adjustment unit 4 includes an arc-shaped shell No. 11, an arc-shaped rotating plate No. 12, a driving member No. 13 and a sliding member No. 14. The arc-shaped shell No. 11 is fixedly connected to the wall-mounted plate 2. The driving member No. 13 is arranged inside the arc-shaped shell No. 11. The output end of the driving member No. 13 is transmission-connected to the arc-shaped rotating plate No. 12. The inner edge of the arc-shaped rotating plate No. 12 is slidingly fitted with the outer side of the arc-shaped shell No. 11 through a sealing strip. The sliding member No. 14 is fixed to the upper and lower sides of the arc-shaped rotating plate No. 12. The oil replenishing mechanism No. 1 is arranged inside the arc-shaped shell No. 11 and is used to maintain the transmission components on the driving member No. 13.

[0039] The adjustment principle of the lateral adjustment unit 4: the No. 1 driving member 13 drives the No. 1 arc-shaped rotating plate 12 to move along the outside of the No. 1 arc-shaped shell 11. During the rotation, the No. 1 sliding member 14 limits the No. 1 arc-shaped rotating plate 12. The No. 1 arc-shaped rotating plate 12 can drive the vertical adjustment unit 5 and the audio body 1 to rotate horizontally, thereby automatically adjusting the angle between the audio and the horizontal plane.

[0040] For further information, see Figure 4 The first driving member 13 includes a first motor 15, a first driving gear 16, a first transmission gear 17, a first worm 18 and a first worm wheel 19. The first motor 15 is fixed to the inner wall of the first arc shell 11, the first driving gear 16 is fixedly connected to the output end of the first motor 15, the first transmission gear 17 is meshed with the first driving gear 16, the first transmission gear 17 is fixedly connected to the end optical axis of the first worm 18, and the first worm 18 is connected to the first arc shell 11 through a bearing seat. The inner wall of the No. 1 arc shell 11 is rotatably connected, the No. 1 worm wheel 19 is meshed with the No. 1 worm 18, the central axis of the No. 1 worm wheel 19 is rotatably connected with the inner wall of the No. 1 arc shell 11 through a bearing seat, an avoidance groove is provided on one side of the No. 1 arc shell 11, the No. 1 worm wheel 19 is inside the avoidance groove, and two No. 1 rotating gears 20 are symmetrically sleeved on the outer side of the central axis of the No. 1 worm wheel 19, and the inner side of the No. 1 arc rotating plate 12 is evenly provided with No. 1 tooth grooves 21 meshed with the No. 1 rotating gear 20.

[0041] The principle of the No. 1 driving member 13 driving the No. 1 arc-shaped rotating plate 12 to rotate is as follows: the No. 1 motor 15 drives the No. 1 driving gear 16 to rotate, the No. 1 driving gear 16 drives the No. 1 transmission gear 17 to rotate, the No. 1 transmission gear 17 drives the No. 1 worm 18 to rotate, the No. 1 worm 18 drives the No. 1 worm wheel 19 to rotate, the No. 1 worm wheel 19 drives the No. 1 rotating gear 20 to rotate, and the reaction force generated when the No. 1 rotating gear 20 and the No. 1 tooth groove 21 are engaged will drive the No. 1 arc-shaped rotating plate 12 to rotate along the outside of the No. 1 arc-shaped shell 11.

[0042] For further information, see Figure 5 The No. 1 sliding member 14 includes a No. 1 L-shaped fixed plate 22 fixedly connected to the No. 1 arc-shaped rotating plate 12, a No. 1 connecting block 23 is fixed to one side of the No. 1 L-shaped fixed plate 22, a No. 1 connecting block 23 is movably connected to a No. 1 ball 24 on a side close to the No. 1 arc-shaped shell 11, and a No. 1 arc-shaped groove 25 adapted to the No. 1 ball 24 is opened on the No. 1 arc-shaped shell 11.

[0043] When the No. 1 arc-shaped rotating plate 12 moves outside the No. 1 arc-shaped shell 11, it will also drive the No. 1 ball 24 to roll in the No. 1 arc-shaped groove 25, thereby reducing the friction of the No. 1 arc-shaped rotating plate 12 during rotation. At the same time, the length of the No. 1 arc-shaped groove 25 determines the maximum moving range of the horizontal rotation angle of the No. 1 arc-shaped rotating plate 12, and the limiting effect is better.

[0044] For further information, see Figure 6 The No. 1 oil replenishing mechanism 8 includes a No. 1 sealed piston cylinder 26, and a No. 1 sealed bearing 27 is embedded at both ends of the No. 1 sealed piston cylinder 26. The No. 1 sealed piston cylinder 26 is connected to the inner wall of the No. 1 arc-shaped shell 11 through a fixed frame. The interior of the No. 1 sealed bearing 27 runs through a No. 1 reciprocating screw 28, and the outer side of the No. 1 reciprocating screw 28 is sleeved with a No. 1 slide seat 29. The outer ring of the No. 1 slide seat 29 is fixedly installed with a No. 1 piston plate 30. Four No. 1 limit rods 31 are fixed between the inner ends of the No. 1 sealed piston cylinder 26.

The bottom of the No. 1 sealing piston cylinder 26 is connected to a No. 1 oil outlet pipe 34 through a one-way valve. The end of the No. 1 oil outlet pipe 34 away from the No. 1 sealing piston cylinder 26 is fixed with a No. 1 oil delivery pipe 35. A plurality of No. 1 oil injection nozzles 36 are provided at the bottom of the No. 1 oil delivery pipe 35. The plurality of No. 1 oil injection nozzles 36 are respectively located directly above the No. 1 worm gear 18.

[0045] Specifically, when the No. 1 motor 15 is started to adjust the angle, the No. 1 transmission gear 17 also drives the No. 2 transmission gear 32 to rotate, and the No. 2 transmission gear 32 drives the No. 1 reciprocating screw 28 to rotate. The No. 1 reciprocating screw 28 rotates inside the No. 1 sealed piston cylinder 26 through the No. 1 sealed bearing 27, and then drives the No. 1 slide seat 29 and the No. 1 piston plate 30 to reciprocate left and right and cooperate with the No. 1 sealed piston cylinder 26 to perform piston movement, which is beneficial to generate negative pressure inside the No. 1 sealed piston cylinder 26 and pass through the No. 1 sealed bearing 27. The oil inlet pipe 33 extracts the lubricating oil from the No. 1 oil storage tank 7 in a quantitative manner, and transports the lubricating oil to the No. 1 oil delivery pipe 35 through the No. 1 oil outlet pipe 34 when pushing the lubricating oil, so that multiple No. 1 oil nozzles 36 can evenly spray the lubricating oil onto the No. 1 worm 18 and the No. 1 worm wheel 19. The meshing of the No. 1 worm 18 and the No. 1 worm wheel 19 will produce a splashing effect, and then the lubricating oil will be applied to the No. 1 rotating gear 20, the No. 1 driving gear 16 and the No. 1 transmission gear 17, thereby performing synchronous maintenance on the gear set.

[0046] Example 2: Please refer to Figure 7 - Fig.10 , this implementation further illustrates Example 1.

[0047] Specifically, the vertical adjustment unit 5 includes a No. 2 arc shell 37, a No. 2 arc rotating plate 38, a No. 2 driving member 39 and a No. 2 sliding member 40. The No. 2 arc shell 37 is fixedly connected to one end of the No. 1 arc rotating plate 12. The No. 2 driving member 39 is arranged inside the No. 2 arc shell 37. The output end of the No. 2 driving member 39 is transmission-connected to the No. 2 arc rotating plate 38. The inner edge of the No. 2 arc rotating plate 38 is slidingly fitted with the outer side of the No. 2 arc shell 37 through a sealing strip. The No. 2 sliding member 40 is fixed to the front and rear sides of the No. 2 arc rotating plate 38. The No. 2 oil replenishing mechanism 10 is arranged inside the No. 2 arc shell 37 and is used to maintain the transmission components on the No. 2 driving member 39.

[0048] The adjustment principle of the vertical adjustment unit 5 is as follows: the No. 2 driving member 39 drives the No. 2 arc-shaped rotating plate 38 to move along the outside of the No. 2 arc-shaped shell 37. While rotating, the No. 2 sliding member 40 limits the No. 2 arc-shaped rotating plate 38. The No. 2 arc-shaped rotating plate 38 can drive the audio body 1 to rotate in the vertical direction, thereby automatically adjusting the tilt angle of the audio.

[0049] The second driving member 39 includes a second motor 41, a second driving gear 42, a third transmission gear 43, a second worm 44 and a second worm wheel 45. The second motor 41 is fixed to the inner wall of the second arc-shaped housing 37. The second driving gear 42 is fixedly connected to the output end of the second motor 41. The third transmission gear 43 is meshed with the second driving gear 42. The third transmission gear 43 is fixedly connected to the end optical axis of the second worm 44. The second worm 44 is connected to the second worm wheel 45 through a bearing seat. The inner wall of the arc shell 37 is rotatably connected, the No. 2 worm wheel 45 is meshed with the No. 2 worm 44, the center axis of the No. 2 worm wheel 45 is rotatably connected with the inner wall of the No. 2 arc shell 37 through a bearing seat, an avoidance groove is provided on one side of the No. 2 arc shell 37, the No. 2 worm wheel 45 is inside the avoidance groove, and two No. 2 rotating gears 46 are symmetrically sleeved on the outer side of the center axis of the No. 2 worm wheel 45, and the inner side of the No. 2 arc rotating plate 38 is evenly provided with No. 2 tooth grooves 47 meshed with the No. 2 rotating gear 46.

[0050] The principle of the No. 2 driving member 39 driving the No. 2 arc-shaped rotating plate 38 to rotate is as follows: the No. 2 motor 41 drives the No. 2 driving gear 42 to rotate, the No. 2 driving gear 42 drives the No. 2 transmission gear 32 to rotate, the No. 2 transmission gear 32 drives the No. 2 worm 44 to rotate, the No. 2 worm 44 drives the No. 2 worm wheel 45 to rotate, the No. 2 worm wheel 45 drives the No. 2 rotating gear 46 to rotate, and the reaction force generated when the No. 2 rotating gear 46 and the No. 2 tooth groove 47 are engaged will drive the No. 2 arc-shaped rotating plate 38 to rotate along the outside of the No. 2 arc-shaped shell 37.

[0051] At the same time, if Fig.10As shown, the No. 2 sliding member 40 includes a No. 2 L-shaped fixing plate 48 fixedly connected to the No. 2 arc-shaped rotating plate 38, a No. 2 connecting block 49 is fixed to one side of the No. 2 L-shaped fixing plate 48, a No. 2 connecting block 49 is movably connected to a No. 2 ball 50 on one side of the No. 2 connecting block 49 close to the No. 2 arc-shaped shell 37, and a No. 2 arc-shaped groove 51 adapted to the No. 2 ball 50 is opened on the No. 2 arc-shaped shell 37.

[0052] When the second arc-shaped rotating plate 38 moves outside the first arc-shaped shell 11, it will also drive the second ball 50 to roll in the second arc-shaped groove 51, thereby reducing the friction of the second arc-shaped rotating plate 38 during rotation. At the same time, the length of the second arc-shaped groove 51 determines the maximum moving range of the horizontal rotation angle of the second arc-shaped rotating plate 38, and the limiting effect is better.

[0053] In addition, if Fig. 9 As shown, the No. 2 oil replenishing mechanism 10 includes a No. 2 sealed piston cylinder 52, which is connected to the inner wall of the No. 2 arc-shaped shell 37 through a fixing frame, and No. 2 sealed bearings 53 are embedded at both ends of the No. 2 sealed piston cylinder 52, and a No. 2 reciprocating screw 54 is penetrated inside the No. 2 sealed bearing 53, and a No. 2 slide seat 55 is sleeved on the outer side of the No. 2 reciprocating screw 54, and a No. 2 piston plate 56 is fixedly installed on the outer ring of the No. 2 slide seat 55, and four No. 2 limiting rods 57 are fixed between the inner ends of the No. 2 sealed piston cylinder 52, and the No. 2 piston plate 56 and the No. 2 limiting rod 57 are slidably penetrated and connected, and one end of the No. 2 reciprocating screw 54 is fixed. It is connected to a No. 4 transmission gear 58, which is meshed with a No. 3 transmission gear 43.

The end of the No. 2 oil inlet pipe 59 away from the No. 2 sealed piston cylinder 52 passes through the No. 2 arc shell 37 and is interconnected with the No. 2 oil storage tank 9. The bottom of the No. 2 sealed piston cylinder 52 is connected to a No. 2 oil outlet pipe 60 through a one-way valve. The end of the No. 2 oil outlet pipe 60 away from the No. 2 sealed piston cylinder 52 is fixed with a No. 2 oil delivery pipe 61. A plurality of No. 2 oil nozzles 62 are provided at the bottom of the No. 2 oil delivery pipe 61, and the plurality of No. 2 oil nozzles 62 are respectively located directly above the No. 2 worm gear 44.

[0054] Specifically, when the No. 2 motor 41 is started to adjust the angle, the No. 2 transmission gear 32 also drives the No. 3 transmission gear 43 to rotate, and the No. 3 transmission gear 43 drives the No. 2 reciprocating screw 54 to rotate. The No. 2 reciprocating screw 54 rotates inside the No. 2 sealed piston cylinder 52 through the No. 2 sealed bearing 53, and then drives the No. 2 slide seat 55 and the No. 2 piston plate 56 to reciprocate left and right and cooperate with the No. 2 sealed piston cylinder 52 to perform piston movement, which is conducive to generating negative pressure inside the No. 2 sealed piston cylinder 52 and passing through the No. 2 The oil inlet pipe 59 extracts the lubricating oil from the No. 2 oil storage tank 9 in a quantitative manner, and transports the lubricating oil to the No. 2 oil delivery pipe 61 through the No. 2 oil outlet pipe 60 when pushing the lubricating oil, so that the multiple No. 2 oil nozzles 62 can evenly spray the lubricating oil onto the No. 2 worm 44 and the No. 2 worm wheel 45. The meshing of the No. 2 worm 44 and the No. 2 worm wheel 45 will produce a splashing effect, and then the lubricating oil will be applied to the No. 2 rotating gear 46, the No. 2 driving gear 42 and the No. 3 transmission gear 43, thereby performing synchronous maintenance on the gear set.
