DETAILED DESCRIPTION
[0022] The technical solution of the present invention is described below with reference to the accompanying drawings and embodiments.
[0023] like Figure 1-5 As shown, the intelligent voice bed frame described in the present invention includes a chassis 1 and a bed board 2, and is characterized in that: a turntable assembly and a controller 43 are provided on the chassis 1, the bed board 2 is rotatably mounted on the turntable assembly, and the turntable assembly is provided with an overload protection assembly; a sensing diaphragm 4 is provided on the bed board 2, and a functional component is provided on the sensing diaphragm 4, the controller 43 connects the functional component and the turntable assembly through a line, and the controller 43 is provided with a communication module, a voice module 45 and a power interface 46.
[0024] The bed board 2 and chassis 1 are both circular frame structures, arranged concentrically. The advantages of the frame structure are overall lightweight, convenient component installation and wiring routing, and greater rotational freedom of the bed board 2. The bed board 2 is mounted above the chassis 1 via a turntable assembly. The turntable assembly is rotatably connected to the bed board 2, meaning that the bed board 2 can rotate independently, allowing the user to directly adjust the direction of the bed board 2.
[0025] The turntable assembly is powered and can drive the bed board 2 to rotate. The controller 43 is used for the turntable assembly. The controller 3 can detect the rotation angle of the turntable assembly, thereby determining the orientation angle of the bed board 2 and driving the bed board 2 to rotate to adjust the orientation based on user instructions. It is understood that the turntable assembly is located at the center of the chassis 1. Of course, the turntable assembly is also supported at the center of the bed board 2. To prevent the bed board 2 from tilting, an overload protection component is provided on the turntable assembly. The overload protection component is arranged around the rotation center of the bed board 2 to improve the load-bearing capacity and stability of the bed board 2.
[0026] Furthermore, the bed board 2 is provided with a sensing diaphragm 4. When the sensing diaphragm 4 covers the upper surface of the bed board 2, it can fill the gaps in the frame structure of the bed board 2. Of course, a mattress will be laid on the bed board 2 when in use. The sensing diaphragm 4 is provided with functional components. The controller 43 can control the operation of the functional components. The power interface 46 is connected to an external power supply to provide power to the above components. The controller 43 includes a control panel and a remote control. The control panel is usually installed on the edge of the bed board 2. The remote control can remotely control the controller 43 to execute the corresponding degree, so that the user can lie on the bed board 2 to adjust the direction without having to fumble with the control panel. Preferably, the controller 43 is also provided with a voice module 45. The voice module 45 can recognize voice, so that the user can control the rotation of the bed board 2 by voice, control the execution of each functional component and realize the corresponding function.
[0027] Specifically, the functional components include a resonant coil, which is arranged on the inductive diaphragm 4, and a speaker 5 is provided on the bed board 2 or the chassis 1; an audio module 51 is provided on the controller 43, and the audio module 51 is connected to the resonant coil and the speaker 5 through a line. It can be understood that the inductive diaphragm 4, the resonant coil and the electromagnetic coil are components of the speaker, and the principle of the speaker's sound generation is not described here. The inductive diaphragm 4 of the present invention is paired with the resonant coil, and the resonant coil can drive the inductive diaphragm 4 to vibrate. Furthermore, the speaker 5 can be set on the base 1, the speaker 5 can play music, and the speaker 5 is connected to the controller 43 through a line. The audio module 51 can process the audio signal and forward it to the speaker 5 to play music, and the audio module 51 sends a synchronous frequency to the resonant coil to make the inductive diaphragm 4 produce corresponding vibrations, thereby promoting falling asleep and improving sleep quality under music and vibration of the same frequency.
[0028] Preferably, the sensing diaphragm 4 is provided with a plurality of pressure sensors 41, which are connected to a controller 43 via lines. The pressure sensors 41 are used to detect the load borne by the bed board 2, that is, the weight of the person sleeping on the bed board 2. This load causes pressure on the sensing diaphragm 4 and triggers the pressure sensors 41. The pressure sensors 41 send a load signal to the controller 43, which can automatically adjust the output power of the audio module 51 and change the vibration intensity of the resonant coil and the sensing diaphragm 4.
[0029] The functional components further include a temperature sensor 52 , an infrared light generator 53 , a decorative light source 54 and a magnet 55 . The temperature sensor 52 , the infrared light generator 53 and the decorative light source 54 are all connected to the controller 43 via lines.
[0030] It is understandable that the decorative light source 54 is composed of a number of light-emitting chips, usually in the form of a light strip, distributed on the sensing diaphragm 4 or arranged around the edge of the bed frame 2.
[0031] The infrared light generator 53 can output high-energy infrared light, which is projected onto the sensing diaphragm 4 or the mattress thereon, thereby improving the physical comfort of the human body. Correspondingly, a temperature sensor 52 is also provided on the sensing diaphragm 4 to monitor the temperature, and the controller 43 can adjust the working parameters of the infrared light generator 53 in real time.
[0032] The number of the magnets 55 is related to the area of the bed board 2. The distribution of the magnets 55 can be flexible, but generally follows a circular distribution around the rotation center of the bed board 2. The magnets 55 can emit magnetic waves, improve human circulation by adjusting the magnetic field, and play a role in health care.
[0033] The chassis 1 is provided with a first angle sensor 42, which is connected to a controller 43 via a line; the bed board 2 is provided with a plurality of trigger members 44, which are arranged around the rotation center of the bed board 2. When the bed board 2 rotates, the plurality of trigger members 44 can pass through and trigger the first angle sensor 42.
[0034] It can be understood that the bed board 2 and the chassis 1 can rotate relative to each other, and the first angle sensor 42 is arranged on the chassis 1 near its edge. A number of auxiliary columns 25 are provided on the outer periphery of the bed board 2, and a number of triggers 44 are respectively arranged on the auxiliary columns 25. When the bed board 2 and the chassis 1 rotate relative to each other, the triggers 44 will pass through the first angle sensor 42 in turn. The triggers 44 can be encoded so that they can be recognized by the first angle sensor 42 and send corresponding signals to the controller 43, so that the controller 43 knows the real-time orientation of the bed board 2, and then controls the turntable assembly to drive the bed board 2 to rotate clockwise or counterclockwise by a certain angle.
[0035] The trigger 44 can be coded, which has the advantage that the initial state or angle of the bed board 2 can be initialized. After setting the initial starting point, the controller 43 accurately controls the rotation angle of the bed board 2 according to the angular velocity and running time of the bed board 2.
[0036] Specifically, the turntable assembly includes a support sleeve 3, a transmission disk 22 and a drive motor 11. The lower end of the support sleeve 3 is connected to the chassis 1. A first sleeve 31 and a second sleeve 33 are provided on the support sleeve 3. The upper end of the first sleeve 31 is fixedly connected to the bed board 2, and a bearing 32 is provided between the first sleeve 31 and the support sleeve 3; the transmission disk 22 is provided between the bed board 2 and the chassis 1, the transmission disk 22 is connected to the second sleeve 33, and a bearing 32 is provided between the second sleeve 33 and the support sleeve 3; the drive motor 11 is connected to the bed board 2 through the transmission disk 22, and an overload protection component is provided on the transmission disk 22.
[0037] The support sleeve 3 is located at the center of the chassis 1. It is a hollow structure. The lower end of the support sleeve 3 is provided with an extension structure (located horizontally to increase the contact surface) to enhance the connection stability of the support sleeve 3 to the chassis 1. The first shaft sleeve 3 is assembled on the support sleeve 3 via a bearing 32. The upper end of the first shaft sleeve 3 is also provided with an extension structure (located horizontally to increase the contact surface) to enhance the connection stability between the first shaft sleeve 3 and the bed board 2, allowing the bed board 2 to rotate relative to the chassis 1.
[0038] Furthermore, the transmission disc 22 is mounted on the second sleeve 33 , and the second sleeve 33 is connected to the support sleeve 3 through the bearing 32 , so that the transmission disc 22 can also rotate relative to the chassis 1 , and then the drive motor 11 can drive the bed board 2 to rotate through the transmission disc 22 .
[0039] The turntable assembly also includes a transmission gear 21, which surrounds and is concentric with a transmission disc 22. The transmission gear 21 and the transmission disc 22 are fixedly connected by a plurality of connecting rods 23. The drive motor 11 is provided with an output gear 12, which meshes with the transmission gear 21. The bed board 2 is provided with a plurality of friction members 24, which are spaced apart and arranged around a first sleeve 31 and abut against the transmission disc 22. The transmission gear 21 has a larger diameter and surrounds the transmission disc 22, with the two being integrally connected by connecting rods 23. The larger diameter of the transmission gear 21 provides more meshing teeth, and the smaller diameter and fewer teeth of the output gear 12 on the drive motor 11 create a large transmission ratio between the output gear 12 and the transmission gear 21. This converts the high speed of the drive motor 11 into high torque, thereby driving the bed frame 2 at a lower speed and ensuring more stable rotation of the bed frame 2.
[0040] The bed board 2 is provided with a plurality of friction members 24, which are arranged in sequence and spaced around the first sleeve 31. The friction members 24 are abutted against the transmission disc 22. The friction members 24 are used to provide a transmission connection so that the transmission disc 22 can drive the bed frame 2 to rotate. Specifically, the plurality of friction members 24 are connected to an extension structure at the upper end of the first sleeve 31, and the extension structure is fixedly connected to the bed frame 2. It can be understood that the friction members 24 have elastic potential energy, so that their friction surfaces are abutted against the transmission disc 22, and when the transmission disc 22 rotates, it can drive the first sleeve 31 and the bed frame 2 to rotate. In particular, the plurality of friction members 24 are arranged around the first sleeve 3. When the bed frame 2 deflects slightly to either side, the plurality of friction members 24 can maintain contact with the transmission disc 22 through a retractable elastic mechanism with only a small amount of travel, thereby avoiding failure of the transmission connection.
[0041] The overload protection component includes a first balance wheel 201 and a second balance wheel 202. A plurality of first balance wheels 201 are provided on the bed board 2, and the plurality of first balance wheels 201 are arranged in sequence around the first shaft sleeve 31, and a gap is provided between the rolling surface of the first balance wheel 201 and the transmission gear disc 21; a plurality of second balance wheels 202 are provided on the chassis 1, and the plurality of second balance wheels 202 are arranged in sequence around the second shaft sleeve 33, and a gap is provided between the rolling surface of the second balance wheel 202 and the transmission disc 22.
[0042] The first balance wheel 201 is arranged between the bed board 2 and the transmission gear disc 21, and the second balance wheel 220 is arranged between the transmission disc 22 and the chassis 1. It can be understood that when a person is standing, sitting, or lying on the bed board 2, his or her position is usually not at the center of the bed board 2, so that the bed board 2 is generally in an unbalanced state, and the load will cause the bed board 2 to always tend to one side. The above-mentioned rotating mechanism can provide a certain rigidity to ensure that the bed board 2 tends to be horizontal. When the load on the bed board 2 is large or it is subjected to a certain impact, the first balance wheels 201 can provide support to prevent the bed board 2 from tilting excessively, so that it can rotate normally. Furthermore, when the load on the bed board 2 is large, it will also cause the transmission gear disc 21 and the transmission disc 22 to deflect. The second balance wheels 220 can provide support to prevent the transmission disc 22 from tilting excessively, so as to ensure the stable engagement between the output gear 12 on the drive motor 11 and the transmission gear disc 21.
[0043] When the bed board 2 is horizontal, i.e., in a low-load state, the first balancing wheel 201 does not contact the transmission gear plate 21. The bed frame 2 and the chassis 1 are connected only by the first bushing 31 and the support sleeve 3, allowing the bed frame 2 to rotate easily. Similarly, the second balancing wheel 220 does not contact the transmission plate 22 under normal conditions, reducing frictional resistance of the transmission plate 22 and alleviating the load on the drive motor 11.
[0044] The support sleeve 3 is provided with a central axis 35 within it, with several bearings 32 disposed between the central axis 35 and the support sleeve 3. The upper end of the central axis 35 is inserted through the bed board 2. The chassis 1 is provided with a centering base 13, and the lower end of the central axis 35 is provided with a centering sleeve 34, which is mounted on the centering base 13. The lower end of the central axis 35 is fixed to the centering sleeve 34. The centering sleeve 34 is assembled with the centering base 13 to ensure concentricity between the bed frame 2 and the chassis 1. In particular, a buffer structure, such as a gasket or spring, can be provided between the centering sleeve 34 and the centering base 13 to absorb a portion of the vertical impact on the bed frame 2 and prevent malfunction of the rotating mechanism. Furthermore, the central axis 35 is hollow, and the wiring of the angle sensor 42, the sensing diaphragm 4, and the controller 43 can be routed through the central axis 35 to prevent entanglement.
[0045] Several of the connecting rods 23 are provided with trigger members 44, and the chassis 1 is provided with a second angle sensor 47. When the transmission disk 22 rotates, the trigger members 44 on the several connecting rods 23 can respectively pass through and trigger the second angle sensors 47. The second angle sensor 47 is connected to the controller 43 via a line. As described above, several trigger members 44 are provided on the connecting rods 23, and the chassis 1 is provided with a support beam 14. The support beam 14 is used to mount the second angle sensor 47, raising it and placing it close to the trigger member 44 on the connecting rod 23. Of course, the support beam 14 itself is an assembly with the chassis 1, which can enhance the structural strength of the chassis 1. The second angle sensor 47, in conjunction with the several trigger members 44, can detect the rotation angle of the transmission gear plate 21 and the transmission disk 22, allowing the controller 43 to monitor and calculate the rotation angle of the drive motor 11, the transmission disk 22, and the bed frame 2.
[0046] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
