[0007] Furthermore, the balance compensation module includes a compensation support spring, which is arranged at any one of the support part and the shaking part, and there is a gap between the compensation support spring and the other of the support part and the shaking part.

[0008] Furthermore, the balance compensation module also includes an adjustment component, which is arranged at one of the support part and the shaking part. The adjustment component includes a screw rod and a nut sleeved on the screw rod, and one end of the compensation support spring abuts against the nut.

[0009] Furthermore, the balance compensation module further includes a sleeve, which is disposed at the other of the support portion and the shaking portion, and a portion of the compensation support spring is located in the sleeve.

[0010] Furthermore, the shaking and relaxing device also includes a telescopic module, which is arranged on the shaking part, and has an extended state and a retracted state.

[0017] In the shaking and relaxing device of the present application, when the motor drives the eccentric wheel to rotate, the position of the center of mass of the eccentric wheel relative to its rotation center changes continuously, thereby generating a periodically changing centrifugal force, which can drive the shaking part to shake back and forth up and down with the elastic connection part as a variable fulcrum.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0029] The following is combined with Figures 1 to 5 , the shaking and relaxing device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0030] See also Figure 1 and Figure 2The embodiment of the present application discloses a rocking relaxation device, which can be used for rocking relaxation of users and can help them fall asleep quickly. For example, the rocking relaxation device can be a rocking chair. Specifically, the rocking relaxation device can include a support part 100, a rocking part 200, an elastic connection part 300, a driving mechanism 400, a noise reduction and shock absorption module 500, and a balance compensation module 600. The rocking part 200 is arranged above the support part 100, and the elastic connection part 300 is connected between the support part 100 and the rocking part 200. In the case where the rocking and relaxing device is a rocking chair, the support part 100, the rocking part 200 and the elastic connection part 300 can be a tubular structure or a plate structure, and the entire rocking and relaxing device can be an integral structure in which the support part 100, the elastic connection part 300 and the rocking part 200 are connected in sequence, wherein the support part 100 can be supported on the ground, the elastic connection part 300 is connected to the support part 100, and the elastic connection part 300 extends back to the ground and is curved in an arc shape, the rocking part 200 is connected to the elastic connection part 300, the rocking part 200 is used to support the user's body, and the rocking part 200 can rock back and forth up and down with the elastic connection part 300 as a variable fulcrum. It can be understood that in the case where the rocking part 200 is a tubular member, a mesh structure can be welded on the rocking part 200 to support the user's body; in the case where the rocking part 200 is a plate-like structure, the rocking part 200 itself can play a role in supporting the user's body.

[0031] In the embodiment of the present application, the driving mechanism 400 is connected to the shaking part 200 through the noise reduction and shock absorption module 500, and the driving mechanism 400 is configured to drive the shaking part 200 to shake relative to the supporting part 100. Exemplarily, the driving mechanism 400 and the noise reduction and shock absorption module 500 can be arranged on the back side of the shaking part 200, and the driving mechanism 400 can include a motor 410 and an eccentric wheel 420 driven and rotated by the motor 410, and the position of the center of mass of the eccentric wheel 420 relative to its rotation center is constantly changing, thereby generating a periodically changing centrifugal force, which can drive the shaking part 200 to reciprocate up and down with the elastic connection part 300 as a variable fulcrum. In one rotation cycle of the eccentric wheel 420, the magnitude and direction of the centrifugal force change smoothly with the rotation of the eccentric wheel 420, and this continuity and stability make the shaking of the shaking part 200 more natural and smooth.

[0032] It should be noted that, from a mechanical point of view, the “variable fulcrum” mentioned in the embodiments of the present application refers to the elastic connection part 300, which, through its bending and elastic characteristics, provides a support point for the shaking part 200 connected thereto that can be changed according to the force conditions. When the shaking part 200 is subjected to pressure or external force, the elastic connection part 300 will deform, thereby changing the relative position or angle between the shaking part 200 and the support point.

[0033] In a further technical solution, the driving mechanism 400 may further include a bearing seat 430, and the rotating shaft of the eccentric wheel 420 is rotatably disposed on the bearing seat 430. By disposing the bearing seat 430, the stability of the operation of the driving mechanism 400 can be improved.

[0034] In the embodiment of the present application, the noise reduction and shock absorption module 500 may include a shock absorption bracket 510 and a shock absorption spring 520, wherein the shock absorption bracket 510 is fixedly arranged on the back side of the shaking part 200, one end of the shock absorption spring 520 is connected to the shock absorption bracket 510, and the other end of the shock absorption spring 510 may be connected to the driving mechanism 400. When the driving mechanism 400 operates to drive the shaking part 200 to shake up and down, when the centrifugal force generated by the eccentric wheel 420 acts on the shock absorption spring 510, the shock absorption spring 510 can transmit the driving force to the shaking part 200 while undergoing elastic deformation, that is, the shock absorption spring 510 can play a buffering role and a driving force transmission role, instead of making the driving force generated by the driving mechanism 400 directly act on the shaking part 200. The noise reduction and shock absorption module 500 forms a connection mode between the shaking part 200 and the driving mechanism 400, which can effectively reduce the generation of vibration impact and noise.

[0035] The shaking relaxation device of the present application usually has a certain shaking frequency after being assembled and finalized. When the rotation frequency of the eccentric wheel 420 is close to or consistent with the shaking frequency of the shaking part 200, the shaking part 200 can produce shaking synchronously with the eccentric wheel 420, and the shaking amplitude of the shaking part 200 is large, that is, the two resonate. The inventor found in the research process that when the weight of the user supported on the support part 200 is large, it is difficult for the driving mechanism 400 to drive the shaking part 200 to shake as expected, that is, the shaking frequency and shaking amplitude of the shaking part 200 are not ideal, and it is difficult to effectively relax the user physically and mentally.

[0036] Based on this situation, in an optional embodiment of the present application, the balance compensation module 600 may further include a compensation support spring 610, which is disposed on any one of the support portion 100 and the shaking portion 200, and there is a gap between the compensation support spring 610 and the other of the support portion 100 and the shaking portion 200. For example, see Figure 1 The compensation support spring 610 may be connected to the middle of the support portion 100 , and a gap may be provided between the compensation support spring 610 and the back side of the shaking portion 200 .

[0037] Based on the above scheme, when the user is lighter, the arc-shaped elastic connecting part 300 can provide sufficient support, and the bending deformation of the elastic connecting part 300 is small when the shaking part 200 shakes. At this time, the compensation support spring 610 still has a certain distance from the back side of the shaking part 200, that is, the compensation support spring 610 at this time does not intervene when the user is lighter; and when the user is heavier, the shaking part 200 is pressed down with a larger amplitude and directly abuts against the compensation support spring 610, that is, the compensation support spring 610 can automatically intervene when the user is heavier and apply a supporting force to the shaking part 200, and the greater the deformation amount of the shaking part 200 forcing the compensation support spring 610 to deform, the greater the compensation support force applied by the compensation support spring 610.

[0038] Through the intervention of the balance compensation module 600, different compensation support forces can be provided according to the different weights of the users, so that the shaking part 200 can always be maintained within the appropriate shaking frequency and shaking amplitude, and the shaking of the shaking part 200 can be made quieter, smoother and softer; at the same time, by adding a compensation support spring 610 between the support part 100 and the shaking part 200, part of the pressure can be shared when the user has a heavy weight, and the stress deformation of the original elastic connection part 300 can be reduced, thereby reducing the burden on the original elastic connection part 300 and extending its service life.

[0039] In a further technical solution, the balance compensation module 600 may further include an adjustment component 620, which is disposed at one of the support portion 100 and the shaking portion 200, and the adjustment component 620 is used to adjust the size of the aforementioned gap. Figure 1 The adjustment component 620 is arranged on the support part 100. Specifically, the adjustment component 620 includes a screw rod 621 and a nut 622 sleeved on the screw rod 621. The screw rod 621 can be fixed on the support part 100. One end of the aforementioned compensation support spring 610 abuts against the nut 622, and a gap is formed between the other end of the compensation support spring 610 and the shaking part 200.

[0040] Based on the above solution, by rotating the nut 622, the gap between the compensation support spring 610 and the shaking part 200 can be adjusted. Different users have different weights. By adjusting the size of the gap through the adjustment component 620, the shaking part 200 can interact with the compensation support spring 610 in a better way for users of different weights. Specifically, for users with lighter weight, the gap can be increased to reduce unnecessary friction and resistance; and for users with heavier weight, the gap can be reduced to ensure sufficient support and stability.

[0041] In a further technical solution, the balance compensation module 600 can also include a sleeve 630, which can be arranged on the back side of the shaking part 200. Part of the compensation support spring 610 is located inside the sleeve 630. When the compensation support spring 610 intervenes, the sleeve 630 can provide a guiding function for the compensation support spring 610 to avoid unnecessary friction and sliding between the compensation support spring 610 and the back side of the shaking part 200, so that the compensation support spring 610 can stably provide compensation support force.

[0042] In the aforementioned embodiment, the rocking and relaxing device may be a rocking chair, and in an optional embodiment of the present application, the rocking and relaxing device may also be a rocking bed or a baby cradle. Figure 3 and Figure 4 The support part 100 of the embodiment of the present application may be a bed frame, and the rocking part 200 may be a bed board. The elastic connection part 300 may be a plurality of support springs distributed between the bed frame and the bed board. For example, four support springs are distributed at the four corners of the bed board 200. In a preferred embodiment, the upper end of the elastic connection part 300 is connected and fixed to the bed board, and the lower end of the elastic connection part 300 may be a free end and supported on the bed frame. When the motor 410 drives the eccentric wheel 420 to rotate, the support spring can be deformed in the longitudinal direction, thereby driving the bed board to rock up and down.

[0043] The inventors also found during the research that if too many support springs are arranged, it is difficult for the drive mechanism 400 to produce an obvious shaking feeling when it is in motion. If the number of support springs is small, and when the shaking and relaxing function of the shaking and relaxing device is not needed, for example, when the user just lies down to sleep, it is easy for the support springs to have limited supporting effect on the bed board, and the bed board is easy to tilt due to uneven weighing. Based on this situation, in the case where the shaking and relaxing device is a shaking bed, the shaking and relaxing device can also include a telescopic module 700, and the telescopic module 700 is arranged on the shaking part 200. For example, the telescopic module 700 can be an electric push rod arranged below the shaking part 200, and the base of the electric push rod is arranged on the shaking part 200. The telescopic rod of the electric push rod is used to counter the support part 100. The telescopic module 700 has an extended state and a retracted state. In the extended state, the telescopic module 700 abuts against the support part 100, so that the support spring is in a suspended state. At this time, the telescopic module 700 can effectively support the shaking part 200; in the retracted state, the shaking part 200 is supported by the elastic connecting part 300, and the operation of the driving mechanism 400 can produce an obvious shaking effect.

[0044] In the optional embodiments of this application, see Figure 5The driving mechanism 400 may include a motor 410 and two eccentric wheels 420 driven to rotate by the motor 410, the rotation axes of the two eccentric wheels 420 are perpendicular to each other, and the output shaft of the motor 410 and the rotation axes of the two eccentric wheels 420 are matched through bevel gear transmission. Under such a setting, when the motor 410 drives the two eccentric wheels 420 to rotate, the stress deformation states of the support springs distributed at the four corners of the bed board are not the same, and the stress deformation states of the four support springs will undergo regular periodic changes. In this way, multiple circumferential edge positions of the bed board can undergo periodic ups and downs, thereby simulating the phenomenon that a baby needs to be gently rocked to fall asleep in the arms of an adult, satisfying the user's subconscious sense of security so that the user can fall asleep quickly and sleep soundly, and increasing the user's deep sleep time.

[0045] In the embodiment of the present application, the rocking relaxation device may further include a cushion body 800, which is disposed on the rocking part 200. In the embodiment of the present application, the number of the cushion body 800 may be one or more. When the number of the cushion body 800 is more than one, the cushion bodies 800 may be disposed corresponding to the neck position, waist position, and leg position of the user, and the cushion body 800 may increase the comfort of lying on the rocking part 200.

[0046] In a further technical solution, the shaking relaxation device of the embodiment of the present application may also include a somatosensory music system, which includes an audio vibrator and a speaker arranged on the pad body 800. The speaker may be a dual-channel speaker. When the user is using and experiencing the self-shaking relaxation device of the present application, on the one hand, he can listen to the stereo dual-channel audio signal played by the speaker. On the other hand, the up and down rhythmic movement generated by the audio vibrator acts on the human body, improves vascular microcirculation in a physical way, relaxes nerves and muscles, and promotes a relative reduction in blood pressure and heart rate.

[0047] In a further technical solution, an airbag 900 can also be provided on the cushion body 800. The airbag 900 can be provided corresponding to the neck, waist and legs of the human body. The airbag 900 is connected to an air pump through a trachea. A check valve and an exhaust valve are provided on the trachea. The air pump can supply air to the airbag 900 to meet the physiological curve support requirements of different users, so as to improve the comfort of the user.

[0048] In the embodiment of the present application, the shaking and relaxing device may further include a controller (not shown in the figure) and a pressure sensor (not shown in the figure), wherein the driving mechanism 400 and the pressure sensor are both electrically connected to the controller, the pressure sensor is arranged on the shaking part 200, and the pressure sensor is used to detect a pressure signal. When the pressure signal detected by the pressure sensor is greater than the preset pressure signal, it indicates that a user is lying on the shaking part 200, and the controller 700 receives the pressure signal detected by the pressure sensor, and controls the driving mechanism 400 to move so that the shaking part 200 shakes. In this way, the driving mechanism 400 can automatically start the action when the user lies down, and can automatically turn off when the user leaves, which can avoid the trouble of the user turning on and off the shaking function, and at the same time avoid the user forgetting to turn off the device, resulting in a shortened service life of the shaking and relaxing device and energy waste.

[0049] It should be understood that in the embodiment of the present application, the controller 700 can control the eccentric wheel 420 to rotate in a controlled manner. By changing the centrifugal weight and speed of the eccentric wheel 420, the shaking frequency and amplitude of the shaking part 200 can be changed, and the shaking part 200 can be made to resonate and produce the expected shaking.

[0050] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined.
