[0024] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0025] Reference Figure 1-3 The present invention proposes a vibrating bed leg, comprising a fixing member 1, a supporting member 2 and a vibrating device 5; the supporting member 2 is used to support the ground and is arranged opposite to the fixing member 1 in the longitudinal direction of the fixing member 1; the vibrating device 5 is used to drive the fixing member 1 to vibrate up and down.

[0026] Driven by the vibration device 5, the vibrating bed legs reciprocate and extend, driving the bed body and the mattress to vibrate up and down, causing the bed to vibrate slightly at a certain frequency. These infrasonic vibrations can be felt by the balance receptors in the cochlea, and the tactile receptors can also be clearly felt, and ultimately affect brain electrical activity, stimulate brain waves, and pull the user into a corresponding sleep state, thereby improving sleep quality.

[0027] The vibration device 5 is a brake mechanism with a linear telescopic rod, for example, a cylinder, a motor, etc. with a linear telescopic rod.

[0028] In other embodiments, the vibration device includes an elastic member 3 and a pushing unit 52; the elastic member is disposed between the fixing member and the supporting member; the pushing unit 52 is used to drive the fixing member to vibrate up and down through the elastic member. The pushing unit 52 is a braking mechanism with a linear telescopic rod. For example, a cylinder, a motor, etc. with a linear telescopic rod. The elastic member 3 can reduce shock, making it more comfortable to use.

[0029] The present invention also proposes a vibrating bed leg, comprising a fixing member 1, a supporting member 2, an elastic member 3, a pre-stressing mechanism and a pushing unit 52; the supporting member 2 is used to support the ground, and is arranged opposite to the fixing member 1 in the longitudinal direction of the fixing member 1; the elastic member 3 is arranged between the fixing member 1 and the supporting member 2, and its two ends respectively abut against the fixing member 1 and the supporting member 2; the pre-stressing mechanism is used to pre-stress the elastic member 3; the pushing unit 52 is used to drive the fixing member 1 to vibrate up and down through the elastic member 3.

[0030] Driven by the vibration device 5, the vibrating bed legs reciprocate and extend, driving the bed body and the mattress to vibrate up and down, causing the bed to vibrate slightly at a certain frequency. These infrasonic vibrations can be felt by the balance receptors in the cochlea, and the tactile receptors can also be clearly felt, and ultimately affect brain electrical activity, stimulate brain waves, and pull the user into a corresponding sleep state, thereby improving the sleep experience.

[0031] For example, by detecting and determining the total weight data of the bed and the user and the data analysis of the elastic member 3, a control signal adapted to the current mode is generated through analysis, and the control signal is used to control the pre-stressing mechanism and the pushing unit 52 of the vibration device 5. During rest, there are generally two modes: relaxation and deep sleep. The control unit adjusts the pre-stressing of the spring through the pre-stressing mechanism, and then adjusts the resonant frequency of the reciprocating motion, so that the resonant frequency of the reciprocating motion is suitable for the α wave in the relaxation and rest state, or the θ wave below 5 Hz suitable for deep sleep. The vibration device 5 drives the elastic member 3 to drive the fixing member 1 to vibrate up and down to achieve resonance, and the control of the resonance is used to pull the user into the corresponding sleep state to improve the sleep quality. The vibration device 5 can also generate vibrations that are not suitable for sleep, which are used to wake up the user at a scheduled time.

[0032] The total weight data of the bed body and the user is obtained by analyzing the weight sensor installed on the vibration bed leg. The control unit analyzes the total weight data of the bed body and the user and the data of the elastic member 3, and controls the pushing unit 52 and / or the pre-pressing device of the vibration device 5 to work according to the set rules. The control unit can be an information processor.

[0033] The vibration device 5 and the braking unit of the preload mechanism can adopt motors, electromagnetic coils, piezoelectric ceramics, magnetostrictive devices and other energy conversion devices that can realize the conversion from electrical energy to mechanical vibration. Driving signals of different intensities and frequencies can obtain vibrations of the required amplitude and frequency to meet different vibration frequency requirements.

[0034] In some embodiments, the elastic member 3 is a spring. When there is no direct connection between the fixing member 1 and the supporting member 2, the spring is arranged between the fixing member 1 and the supporting member 2, and when the fixing member 1 and the supporting member 2 are movably plugged in, the spring sleeve is arranged outside the plugging part.

[0035] For the convenience of description and understanding, the following description of the elastic member 3 is replaced by a spring.

[0036] Reference Figure 1 In some embodiments, the pre-stressing mechanism includes a tensioning wire 41, a winding shaft 42 and a driving mechanism 43; one end of the tensioning wire 41 is connected to the fixing member 1; the winding shaft 42 is used to wind the other end of the tensioning wire 41; the driving mechanism 43 is used to drive the winding shaft 42 to rotate; the winding shaft 42 and the driving mechanism 43 follow the elastic member 3 to move close to one end of the support member 2.

[0037] The tension wire 41 can be a steel wire, a wire made of a high-toughness polymer material, or other linear structures having high toughness.

[0038] In order to make the winding shaft 42 and the driving mechanism 43 move with the end of the elastic member 3 close to the support member 2, a baffle 44 can be provided at the end of the elastic member 3 close to the support member 2, and the driving mechanism 43 is connected to the baffle 44. When the winding shaft 42 is wound around the tension wire 41, the maximum length of the spring (elastic member 3) is limited by the baffle 44 and the fixing member 1. In this embodiment, the driving mechanism 43 can be a mechanism using a motor, an electromagnetic coil, or a piezoelectric ceramic brake, which is used to drive the winding shaft 42 to rotate, and is used to adjust the preload of the spring by adjusting the distance between the opposite ends of the fixing member 1 and the support member 2, and limit the maximum extension length of the spring. By adjusting the preload of the spring, the resonant frequency of the spring can be adjusted, and then the resonant frequency of the reciprocating motion of the bed can be adjusted, and the resonant frequency can be adjusted according to actual needs. When the vibration device 5 drives the fixing member 1 to vibrate up and down through the elastic member 3, the winding shaft 42 and the driving mechanism 43 move with the end of the elastic member 3 close to the support member 2, so that the maximum extension length of the spring limited by the tension wire 41 remains unchanged.

[0039] The vibrating bed leg also includes a sleeve 6; the sleeve 6 is sleeved on the outer side of the elastic member 3, the end of the fixing member 1 close to the elastic member 3, and the end of the supporting member 2 close to the elastic member 3, and the sleeve 6 is fixedly connected to the supporting member 2. The function of the sleeve 6 is to limit the elastic member 3 such as the spring, prevent the elastic member 3 from deviating from the position, and ensure the working quality. In order to prevent the shaking of the elastic member 3 from affecting the working accuracy, the diameter of the internal through hole of the sleeve 6 is slightly larger than the diameter of the elastic member 3.

[0040] In some embodiments, the vibration device 5 is disposed on the support member 2 , and the vibration device 5 includes an ejector 51 , and the ejector 51 is used to drive the elastic member 3 under the drive of the pushing unit 52 .

[0041] In some embodiments, the driving unit 52 of the vibration device 5 is a device such as a cylinder or a linear motor that can directly drive the elastic member 3 to reciprocate, or it can be a device composed of a transmission mechanism that can directly drive the elastic member 3 to reciprocate and a power mechanism that provides power to the transmission mechanism.

[0042] In other embodiments, the prestressing mechanism includes a connecting rod 45, a top plate 47 and an adjusting mechanism 46; one end of the connecting rod 45 is connected to the fixing member 1; the top plate 47 presses against the end of the elastic member 3 away from the fixing member 1, and the connecting rod 45 moves through the top plate 47 and the elastic member 3; the adjusting mechanism 46 is arranged on the side of the top plate 47 away from the elastic member 3, and is used to adjust the prestressing parameters of the elastic member 3 by adjusting the relative position of the connecting rod 45 and the top plate 47, such as adjusting the maximum length of the spring. The adjusting mechanism 46 can be an electrically controlled automatic adjusting mechanism 46, or it can be an adjusting mechanism 46 that manually realizes the adjustment function. In this embodiment, the top plate 47 is driven from below by the vibration device 5 to provide power for vibration to achieve vibration.

[0043] In some embodiments, the connecting rod 45 and the adjusting mechanism 46 can be replaced by linear motors, cylinders and other devices, in which a movable rod that can be longitudinally extended and retracted can realize the function of the connecting rod 45.

[0044] In other embodiments, the fixing member 1 is provided with a convex rod 11 protruding downward; the support member 2 is provided with a clearance groove corresponding to the convex rod 11; the support member 2 is provided with a limiting position 21 for limiting the downward movement of the elastic member 3; the vibration bed leg also includes a positioning block, which is used to limit the convex rod 11; the pushing unit 52 of the vibration device 5 drives the fixing member 1 to vibrate up and down by acting on the convex rod 11. In this embodiment, the convex rod 11 is driven by the pushing unit 52 of the vibration device 5, and then the support member 2 is driven to squeeze the elastic member 3 to provide power for vibration.

[0045] Further, the support member 2 is provided with an adjustment hole, which is connected to the position of the positioning block. The positioning block can be manually adjusted through the adjustment hole, and a mechanism for automatically adjusting the positioning block can also be added to the adjustment hole, which is conducive to the diversity of sales.

[0046] The vibrating bed legs can be directly connected to the bed body, or can be used as a modified part to connect to the foot of an existing bed, and can also achieve the function of pulling the user into a corresponding sleeping state, and the elastic part 3 can also achieve a shock-absorbing and buffering effect.

[0047] The present invention further provides an electric bed, comprising a bed body 7 and any one of the above-mentioned vibrating bed legs; the fixing parts 11 of the vibrating bed legs are connected to the bed body 7, and the vibrating bed legs are used to drive the bed body 7 to vibrate up and down according to a set vibration frequency.

[0048] The vibrating bed legs can drive the bed body 7 and the mattress to vibrate up and down, causing the bed to vibrate slightly at a certain frequency. These infrasonic vibrations can be felt by the balance receptors in the cochlea, and the tactile receptors can also feel them clearly, and ultimately affect the brain electrical activity, pulling the user into a corresponding sleeping state. The elastic member 3 can also achieve a shock-absorbing buffering effect.

[0049] Furthermore, the fixing member 11 is detachably connected to the bed body 7. Since the fixing member 11 is detachably connected to the bed body 7, when a vibrating bed leg has a problem, the vibrating bed leg can be replaced more conveniently, making it more convenient to use. In some embodiments, the vibrating bed legs can be controlled separately to facilitate the replacement of the bed foot, for example, three of the vibrating bed legs can be extended, while the length of the vibrating bed leg to be replaced remains unchanged.

[0050] In some embodiments, a control device 8 may be installed on the bed. The control device 8 controls the vibration of the bed legs by wire or wirelessly. The control device 8 may be used to set an alarm, select a mode, and other functions.

[0051] The present application also proposes a control method for an electric bed, the electric bed being the electric bed mentioned above, comprising:

[0052] S1. Obtaining the user's physical condition information through a micro-motion sensor arranged on the bed;

[0053] S2, judging the user's state through body state information;

[0054] S3. Match the corresponding vibration mode according to the user's state and execute it.

[0055] In the above step S1, the body state information includes human body sign information such as electrocardiogram and respiratory signal, wherein the bed body includes a mattress, and the micro-motion sensor is arranged on the mattress.

[0056] In the above step S2, the user's state may include an awake state in bed, a relaxed resting state, a deep sleep state, etc.

[0057] In the above step S3, the vibration mode report includes α wave vibration mode, θ wave vibration mode, no vibration mode, massage mode, etc., among which the massage mode, etc. can be completed by multiple devices. For example, the massage mode requires the vibration of the bed legs and the vibration of the massage mechanism in the mattress to complete. The vibration mode can be matched with the user's state, but a user's state can match one or more vibration modes. For example, the relaxation and resting state can match the α wave vibration mode and the massage mode. When the user's state matches multiple vibration modes, the vibration mode matching the user's state can be determined by other conditions. For example, the massage mode can be matched during the day and the α wave vibration mode can be matched at night.

[0058] The vibration mode may not match the user's state. When the set conditions are met, a special vibration mode may be executed, such as a wake-up vibration mode, which automatically enters the wake-up vibration mode when the set time is reached.

[0059] Furthermore, before the step of matching the corresponding vibration mode according to the state of the user and executing the step, it includes:

[0060] S4. According to the current weight of the user and the bed, the working parameters of the vibrating bed legs corresponding to the vibration mode are adjusted.

[0061] In the above step S4, the working parameters include the vibration frequency and vibration amplitude of the vibration device 5, and the preload parameters of the preload mechanism, etc.; because different users may have different compression conditions on the spring, in order to make the stimulation efficiency of the electric bed reach the preset efficiency, the preload parameters, vibration frequency and vibration amplitude are adjusted to make the vibrating bed legs resonate according to the preset vibration frequency to achieve the preset effect.

[0062] The vibrating bed legs, electric bed and control method of the electric bed of the present invention are driven by the vibrating device 5 to reciprocate and retract the vibrating bed legs, drive the bed body 7 and the mattress to vibrate up and down, and make the bed vibrate slightly at a certain frequency. These infrasonic vibrations can be felt by the balance receptors in the cochlea, and the tactile receptors can also be clearly felt, and finally affect the brain electrical activity, pulling the user into a corresponding sleeping state, and the shock-absorbing buffering effect can also be obtained through the elastic member 3.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
