Technical Field

The utility model relates to a physiotherapy and help the dormancy field generally, specifically relates to a physiotherapy and help dormancy power device, is the adjustable power device who carries out various frequency motions to the Simmons mattress support.

Background

Sleep is an important and complex physiological function of the human body. Sleep diseases caused by physiological, psychological, mental, personality and social factors are up to 90, of which more than 20 are high-risk diseases, such as hypertension, arrhythmia, coronary heart disease, pulmonary heart disease, nephropathy, epilepsy, sexual hypofunction, myocardial infarction, cerebral thrombosis, cerebral apoplexy, depression, anxiety and the like, which are closely related to qi and blood stagnation or sleep diseases. According to the statistics of the world health organization, the number of people with sleep disorders in the world accounts for 27 percent of the total population, and the number of people with sleep disorders in China exceeds 3 hundred million as shown by a sleep survey report published by the Chinese sleep research institute.

According to related research reports, the market scale of China relating to the sleep industry is expected to reach more than 4000 billion yuan after 2020. There are only a variety of sleep aid bed-like products on the market today and some prior art relating to such integral sleep aid beds will be briefly described below.

The applicant filed a patent application entitled "multi-degree of freedom sleep-assisting law moving bed" with application number 202020131947.7 on 21/1/2020 in Zhoufheng. The rhythm sleep-assisting bed is also an integral power bed and can provide functions of vertical movement and plane movement.

However, all the above-mentioned prior art beds are integral power beds specially designed for the sleep assisting function. That is, to realize the function of 'sleep aiding', the original common bed must be replaced completely. Therefore, various costs such as large-scale packaging of the double bed, heavy transportation of the double bed, carrying and arrangement of the bed in the house, replacement treatment of a new bed and an old bed and the like can be obviously increased, and huge barriers are brought to the popularization of the requirements of thousands of households.

Most of the power sleep-assisting beds in the prior art have complex structures, and particularly need complex transmission mechanisms of the whole bed. In particular, manufacturers often make only a single sleep-aiding bed in order to reduce the package and facilitate transportation and carrying to home. If a double sleeping bed needs to be purchased, two single beds need to be purchased and used together, or the double sleeping bed is customized, so that the requirement of the double sleeping bed can be met, and the double sleeping bed is difficult to popularize effectively.

In addition, it is important that the various sleep-assisting beds in the prior art are not ideal in terms of the effects of "physical therapy (qi and blood dredging)" and "sleep-assisting".

Detailed Description

The preferred embodiments of the physiotherapy and sleep aid power device of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, like numbering represents like elements.

The description of the exemplary embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description, relative terms such as "front," "back," "upper," "lower," "left," "right," "top" and "bottom" as well as derivatives thereof (e.g., "horizontal," "vertical," "downward," "upward"), and the like, are to be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as "connected," "coupled," and "interconnected," refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both removable or rigid attachments or relationships, unless expressly described otherwise. Additionally, the terms "comprises," "comprising," "includes," "including," and the like are intended to include but not be limited to the listed components or elements, i.e., there may be additional unspecified components or elements on top of the listed components or elements.

Fig. 1A and 1B show a physiotherapy and sleep aid power device 1 according to a preferred embodiment of the present invention. The physiotherapy and sleep aid power device 1 can be used, for example, in a split bed frame. The so-called "split bed frame" includes only the peripheral frame and the bedside backrest, not the middle mattress support. The physiotherapy and sleep aid power device 1 according to the preferred embodiment of the present invention can support a mattress (e.g., simmons) independently of a bed frame to perform physiotherapy (ventilation of qi and blood) and sleep aid exercises.

As shown in fig. 1A and 1B, the physiotherapy and sleep-assisting power device 1 mainly includes a central support unit a, a peripheral support unit B, and a bed plate bracket C. The central support unit a and the peripheral support unit B support the bed plate bracket C together, and further support a mattress (not shown). As the name implies, the central support unit a supports at a substantially central position of the top plate bracket C, while the peripheral support unit B supports at a substantially outer peripheral position of the top plate bracket C. The term "substantially" as used herein means at a location or slightly offset, for example, approximately 0-10% off-center or off-center along the length or width direction.

As shown in fig. 6A, 6B, the center support unit a includes a motor assembly 10. The central support unit a preferably also includes a motor housing 20 as shown in fig. 7A-7D. As shown in fig. 8A, 8B, the motor assembly 10 may be supported on a motor frame 20.

In the preferred embodiment of the present invention as shown in the drawings, it is preferable to include four peripheral support units B provided at four corner positions of the deck bracket C, respectively. It should be understood that the number and location of the perimeter support units B may vary. For example, the peripheral support unit B may be supported at a substantially middle position of the outer periphery of the deck bracket C. Also for example, more than four peripheral support units B may be employed if desired.

Fig. 2A, 2B and 2C show a vibration mechanism used in the motor assembly 10, specifically, a combined type eccentric vibration mechanism 11 having an amplitude changing function. The existing eccentric vibration mechanism is provided with an eccentric wheel on a motor shaft, so that horizontal eccentric vibration is generated. Such known mechanisms for realizing eccentric oscillations by means of eccentrics usually have only one fixed eccentricity. Therefore, if the eccentricity is to be changed to obtain different vibration amplitudes, it is necessary to additionally customize the eccentric mechanism with different eccentricities, and to disassemble and replace the entire mechanism. Moreover, if a plurality of different vibration amplitudes are to be obtained, a plurality of sets of eccentric wheel mechanisms are required to be correspondingly provided, so that the cost is greatly increased, and the change of the vibration amplitude of the whole machine is not facilitated.

The utility model provides a modular eccentric vibration mechanism 11, this modular eccentric vibration mechanism sets up on the motor shaft. Different in the past, the utility model discloses an eccentric vibrating mechanism of combination formula can provide different eccentricities under the condition of not renewal part, and then provides different vibration amplitude.

As shown in fig. 2A, 2B and 2C, the combined eccentric vibrating mechanism 11 mainly includes: a base plate 110, a multi-position eccentric adjustment plate 111, an eccentric shaft member 112, a pilot pin 113, a pressure plate 114, and a plurality of locking screws 115.

The chassis 110 has a central bore 1101 through which the motor shaft extends. In the preferred embodiment, the central bore 1101 is "D" shaped for connection to the motor shaft. Alternatively, the central bore may be a circular bore and connected to the motor shaft, for example by a connecting key. A plurality of eccentric positioning holes 1102 are provided around the center hole 1101, and the distances between the eccentric positioning holes 1102 and the center of the center hole 1101 are different, thereby forming various eccentricities. In the preferred embodiment, eight eccentric locating holes 1102 are provided, which allow eight different eccentricities to be formed. It should be understood that other numbers of eccentric locating holes, less than or more than eight, may be provided as desired.

The multi-position eccentric adjustment disk 111 is coupled to the base plate 110, or may be formed integrally with the base plate 110. The multi-position eccentric adjustment disk 111 is substantially annular, and eight arc-shaped positioning grooves 1111 are provided on an inner surface thereof to correspond to the eccentric positioning holes 1102, respectively. The eight arcuate positioning slots 1111 may, for example, be opposite each other two by two to receive the eccentric shaft 112.

Eccentric shaft 112 has an inverted "T" shape, i.e., has a lateral portion 1121 and a vertical shaft portion 1122. A pin hole 1120 is provided on the lateral portion 1121 to receive the positioning pin 113. The vertical shaft portion 1122 of the eccentric shaft 112 may be relatively offset from the axis of rotation of the motor shaft.

The pressing disk 114 is a disk-shaped member having a central hole 1141. The vertical shaft portion 1122 of the eccentric shaft element 112 extends through the central aperture 1141 of the compacting disk 114. The components of the entire combined eccentric oscillating mechanism 11 can be locked and combined by means of the pressing disk 114 and the locking screw 115.

The assembly process of the combined eccentric oscillating mechanism 11 is as follows. First, the multi-position eccentric adjustment disk 111 is placed on the base disk 110, and the lateral portion 1121 of the eccentric shaft element 112 is placed transversely into two opposed positioning grooves 1111 of the multi-position eccentric adjustment disk 111. The locating pin 113 is then inserted through the pin hole 1120 in the transverse portion 1121 of the eccentric shaft 112 and through an eccentric locating hole 1102 in the base plate 110. Finally, the compression plate 114 is covered and the locking screw 115 is tightened. Thus, the assembly of the entire combined eccentric oscillating mechanism 11 is completed.

As described above, the motor shaft passes through and is connected to the center hole 1101 of the chassis 110, so that the rotational motion of the motor can be transmitted to the combined eccentric vibration mechanism 11. Due to the eccentric arrangement of the eccentric shaft element 112, the combined eccentric oscillating mechanism 11 can generate horizontal direction oscillation (or referred to as "horizontal rotation").

Importantly, the combined eccentric vibration mechanism 11 of the present invention has the function of adjusting the eccentricity. Specifically, as previously described, various eccentricities may be created by different distances between the eccentrically located holes 1102 on the bottom plate 110 and the center of the central bore 1101. If the user wants to use different eccentricities to obtain different vibration amplitudes, he or she releases the pressing plate 114, inserts the eccentric shaft 112 into the other set (two) of positioning slots 1111 of the multi-position eccentric adjustment plate 111 and aligns it with the corresponding eccentric positioning holes 1102 of the bottom plate 110, inserts the positioning pin 113, and finally relocks the pressing plate 114.

In other words, the combined eccentric vibration mechanism 11 of the present invention can provide different eccentricities and thus different amplitudes conveniently by simply rotating the eccentric shaft 112 by an angle without increasing or replacing parts. In the preferred embodiment, different eccentricities are provided, e.g., 0.1mm, 1.35 mm. It should be understood that other numbers of eccentric locating holes can be provided as desired, and other combinations of eccentricities can be used.

It should be understood that although the combined eccentric vibration mechanism 11 according to the preferred embodiment of the present invention has been described above, those skilled in the art can conceive of realizing the vibration mechanism capable of changing the amplitude in other ways. For example, eccentric parts with various specifications can be customized, and a mounting structure convenient to detach and replace quickly is added; making the eccentric part into a combined eccentric part which can be split and combined; a mechanism that allows the eccentric to be automatically switched, etc. is employed. Therefore, the "vibration mechanism having the amplitude changing function" is not limited to the combined eccentric vibration mechanism 11 described above.

Therefore, with the help of the eccentric vibration mechanism which can be additionally arranged on the common motor and the speed regulation function of the motor, the utility model discloses can provide the power source with multiple amplitude and multiple rotational speed. Therefore, experts and/or doctors can conveniently and accurately make specific 'exercise prescriptions' corresponding to people of different ages, different exercise bearing capacities and different health conditions so as to adapt to the requirements of physical therapy and sleep assistance of different people.

Preferably, a flywheel is used in the motor assembly of the present invention. A combined power balance flywheel that may be used in the motor assembly 10 will be described below in conjunction with fig. 3 and 5B.

It is known that the function of a flywheel is to store and release energy during movement, thereby compensating for the lack of energy when the motor load varies. Therefore, the flywheel can share the load of the motor, which is beneficial to prolonging the service life of the motor and improving the stability of the motor in heavy load and high-speed operation.

For this application, the market today offers essentially only flywheels of a single mass, which, once changed, can only be replaced with flywheels of a different mass. As shown in fig. 3, the present invention provides a combined dynamic balance flywheel 12, which includes a flywheel body 121 and a mass adjusting block 122, wherein the mass adjusting block 122 is detachably connected to the flywheel body 121, for example, by a fastener. It should be understood that while only one mass adjustment block 122 is shown, multiple mass adjustment blocks may be employed as desired.

Fig. 5B also illustrates the combined dynamically balanced flywheel 12 used in the motor assembly 10, particularly illustrating its assembly. As can be seen, the combined flywheel 12 is mounted on the motor shaft below the combined eccentric oscillating mechanism 11.

The utility model discloses in, cut apart into the polylith that can be linked into an organic whole to the flywheel, make up the locking as required to can provide the flywheel of different masses very conveniently. In practice, flywheels of different weights may be incorporated in the "sport prescription" in order to provide different comfort levels and different user sensations.

Fig. 4A and 4B illustrate an auxiliary load bearing mechanism (or "load lifting mechanism") used with the motor assembly 10. For lifting the load, a two-shaft motor is used, i.e. the motor has a first shaft on the upper end side and a second shaft 15 on the lower end side. The motor first shaft provides the vibration and acts on the physio/sleep-aid bed, while the motor second shaft 15 is mainly used for auxiliary load-bearing. The auxiliary load bearing mechanism as shown comprises a second motor shaft 15, a base 13, and a base bearing 14 fixed to the base 13 for receiving the second motor shaft 15. Since the motor second shaft 15 is received in the base bearing 14 and plays a certain supporting role, it is possible to share the heavy load applied to the motor shaft, thereby making the normal operation of the motor more stable and contributing to the extension of the service life of the motor.

The eccentric design can result in uneven application of force to the first shaft of the motor, which is detrimental to the motor shaft. When the motor assembly 10 is applied to a physio/sleep aid bed, the damage to the first axis of the motor is multiplied by the load. In order to ensure a balanced stressing of the first shaft of the electric motor, in addition to the above-mentioned auxiliary bearing means for the second shaft of the electric motor, the applicant has additionally designed a stabilizing means which ensures a stable operation of the electric motor.

Fig. 5A and 5B illustrate a stabilizing mechanism used with the motor assembly 10. In principle, as long as the chassis 110 and the multi-position eccentric adjusting disk 111 of the eccentric vibrating mechanism 11 can be kept centered and do not deflect, the centering and the non-deflection of the motor shaft are ensured, so that the normal operation of the motor can be ensured, and the service life of the motor can be prolonged. Therefore, the utility model discloses set up three group's lock neck structures and guaranteed eccentric vibration mechanism 11's dish spare, and then guaranteed the centering of motor shaft and not incline.

Specifically, the journal structure mainly includes a journal bearing 16 closely contacting a disk of the combined eccentric vibration mechanism, and a journal bearing housing 17 supporting the journal bearing 16. The lock neck bearing 16 and lock neck bearing seat 17 are secured to a lower stationary support plate 18 of the motor assembly 10, such as by fasteners. Preferably, the journal bearing 16 is lockable to the disc of the eccentric vibratory mechanism by a journal bearing push rod (not shown) disposed in a journal bearing seat 17.

In operation, the journal bearing 16 is secured to the journal bearing push rod with a locking screw, and after the journal bearing mount 17 is secured, the journal bearing push rod is pushed to cause the journal bearing 16 to cling to the plate of the eccentric vibratory mechanism in operation. Once the stabilization and noiselessness are realized, the positioning fixing screw behind the push rod is locked.

With the help of the above-mentioned stabilizing mechanism of the utility model, the service life of the motor can be further ensured, and ideal use stability and comfort level are provided for the physiotherapy/sleep aiding bed.

Fig. 6A and 6B show the entire motor assembly 10. The motor assembly 10 basically includes a motor and an eccentric oscillating mechanism 11 (fig. 2A, 2B and 2C) as described above, and preferably further includes a combined power balance flywheel 12 (fig. 3) as described above, an auxiliary load mechanism (fig. 4A and 4B) as described above, and a stabilizing mechanism (fig. 5A and 5B) as described above.

The motor may have a housing 101 to protect it. It is further preferred that the motor assembly 10 further comprises a support structure consisting essentially of a lower fixed support disk 18 and an upper rotating support disk 19. In a preferred embodiment of the present invention, the support structure may further include a slider bracket 102, which will be described in detail below. The lower stationary support plate 18 is used to secure the motor and associated mechanisms (e.g., the stabilizing mechanism of fig. 5A and 5B). The upper rotary support disc 19 is associated with the lower fixed support disc 18, for example by means of flexible damping columns, and is connected to the eccentric oscillating mechanism 11 by its central hole. The upper surface of the upper rotary support plate 19 supports the bed plate bracket C, and transmits horizontal vibration (horizontal rotation) to the bed plate bracket C, and further to the mattress.

Fig. 7A-7D illustrate a motor housing 20 for supporting the motor assembly 10.

As shown, the motor housing 20 mainly includes: the device comprises a horizontal slider 21, a horizontal sliding seat 22, a vertical slider 23, a vertical sliding seat 24, a base 25, an adjusting screw 26, a fulcrum connecting plate 27 and an adjusting nut 28. Preferably, in the preferred embodiment of the present invention as shown in the drawings, there are two sets of horizontal sliders and slides, each set including two horizontal sliders 21 and one horizontal slide 22; two sets of vertical slides and carriages are provided, each set comprising one vertical slide 23 and one vertical carriage 24. A slider connection 29 is provided between the corresponding horizontal sliders 21 in the two sets. Fig. 7E shows a slider connection 29, which slider connection 29 is connected to the adjusting nut 28 in addition to the two horizontal sliders 21.

Specifically, the horizontal slider 21 is slidably disposed on the horizontal slider 22, and the vertical slider 23 is slidably disposed on the vertical slider 24. The horizontal slider 22 is fixedly disposed on the base 25 and extends in the longitudinal direction of the base 25. The vertical slide 24 is fixedly provided on the base 25 and extends in the vertical direction of the base 25. An adjusting screw 26 is also fixedly provided on the base 25 and extends in the longitudinal direction of the base 25. Two adjusting nuts 28 having opposite threads are provided at both ends of the adjusting screw 26. If desired, the adjusting screw 26 can be rotated manually or electrically so that the two adjusting nuts 28 at the two ends are moved toward or away from each other by engagement with the adjusting screw 26. The adjusting nut 28 is connected to the horizontal slider 21, preferably by means of a slider connection 29. Thus, movement of the adjustment nut 28 in the horizontal direction along the adjustment screw 26 moves the horizontal slider 21 in the horizontal direction along the horizontal slide 22.

The fulcrum link plate 27 is obliquely arranged and has one end pivotally connected to the horizontal slider 21 and the adjusting nut 28, preferably by means of a slider connection 29. The other end of the fulcrum link plate 27 is pivotally connected to the support structure of the motor assembly 10. Thus, movement of the horizontal slide 21 in a horizontal direction along the horizontal slide 22 causes the fulcrum link plate 27 to pivot, thereby moving the support structure of the motor assembly 10 up and down and causing the entire motor assembly 10 to raise or lower.

The vertical slider 23 is fixedly connected to the slider bracket 102. When the slider bracket 102 moves up and down along with the fulcrum link plate 27, the vertical slider 23 moves in the vertical direction along the vertical slider 24, which ensures that the lower fixed support plate 18 of the support structure of the motor unit 10 can be maintained in a horizontal state without deflection.

Preferably, the motor housing 20 according to the preferred embodiment of the present invention further includes a cushion pad 201, a nylon sheath 202, and a lock nut 203. The cushion pad 201 serves to cushion the impact of the adjustment nut 28. A nylon sheath 202 is used to protect the adjustment screw 26. A lock nut 203 is used to lock the components. Once the motor housing 20 is brought to the desired height by manually or electrically rotating the adjustment screw 26, the lock nuts 203 at both ends of the adjustment screw 26 are tightened to fix the motor housing 20 at the desired height.

Fig. 8A and 8B show a state in which the motor assembly 10 is supported on the motor frame 20 to constitute the center support unit a. Since the motor frame 20 can be adjusted in height as described above, the entire center support unit a can be adjusted to different heights as needed.

Fig. 9A-9C show a bed plate bracket C according to a preferred embodiment of the present invention. As shown, the deck carrier C is of the splice type, comprising a plurality of splice subunits 31, 32, 33 and 34. The splicing subunits are spliced into a whole by splicing connectors 35, 36, 37 and 38. Although a double deck carrier is shown formed from four splice subunits, it should be understood that the number of splice subunits may be increased or decreased as desired, for example, a single deck carrier may be formed from two splice subunits, or a larger size deck carrier may be formed from six splice subunits. In summary, the size of the bed plate bracket C can be adjusted according to the size of the corresponding general bed.

Fig. 10 shows one of the peripheral support units B according to a preferred embodiment of the present invention. As shown, the peripheral support unit B includes an upper member 41, a lower member 42, and a lock nut 43. The upper member 41 and the lower member 42 have screw structures engaged with each other, respectively, so that the height of the entire peripheral support unit B can be adjusted. Once adjusted to the desired height, the upper member 41 and lower member 42 can be locked with the locking nut 43 so that they can no longer move relative to each other and remain at the desired height. In use, the peripheral support units B can be adjusted to the required height according to different heights of the bed, and the rack assembly of the central support unit A can be adjusted to the same height.

It should be understood that while the above describes embodiments in which the peripheral support units B are foot supports, some or all of the peripheral support units B may be replaced with a form similar to the central support unit a (i.e., including a motor assembly that generates vibrations) if greater power is required or a greater variety of combinations are required. In this case, it is also possible to replace the central bearing unit a in the form of a simple support (i.e. not comprising a motor assembly that can generate vibrations) similar to a foot support.

Fig. 11A-11C show a "physiotherapy/sleep aid bed" formed by the physiotherapy and sleep aid power device 1 according to the preferred embodiment of the present invention in combination with a bed frame D. Wherein, the physiotherapy and sleep-aiding power device 1 is completely arranged in the bedstead D, so the physiotherapy and sleep-aiding power device can also be called as a built-in type. In this case, the physiotherapy and sleep aid power unit 1 supports the mattress and transmits horizontal vibrations (horizontal whirling) to the mattress and thus to the physiotherapy/sleep aid user.

With the help of the utility model, the user can select different motion parameters according to the self health condition.

Specifically, in the preferred embodiment described above, the motor may have a total of 9 different speeds, for example, in the range of 30 to 3000RPM, with a different eccentricity of 9 in the range of 0.1 to 10mm, and preferably also a different 3 rd flywheel mass for wheels a, B, C. Therefore, in the case of the horizontal swirl mode, a 9 × 9 × 3 ═ 243 combined mode can be formed in total. In other words, different vibration frequencies can be obtained by means of different motor speeds, and different vibration amplitudes can be obtained by means of the eccentric vibration mechanism. Thus, different combinations can be selected according to different physical conditions of the user, and different 'exercise prescriptions' can be realized according to different persons. For example, high frequency, high amplitude qi and blood circulation may be used for physiotherapy during the day and more "flexible" frequency and amplitude may be used to aid sleep at night.

While the physiotherapy and sleep aid power device of the present invention has been described with reference to the preferred embodiments, it is to be understood that equivalent modifications and changes can be made by those skilled in the art without departing from the spirit of the present invention. For example, the physiotherapy and sleep aid device of the present invention can also be used with other types of conventional bed frames, through suitable flexible connections, in other words, in addition to the mattress, the physiotherapy and sleep aid device of the present invention can also transmit the physiotherapy/sleep aid movements to other parts of the conventional bed. Also for example, in addition to the eccentric horizontal rotation described in the preferred embodiment, it is contemplated that other vibration or motion may be added or substituted. Accordingly, the scope of the invention is not to be limited by the specific disclosure above, but is to be defined by the appended claims.
