Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and in particular to a massage module and an electric bed. Background Art

[0002] In modern society, people often experience muscle fatigue due to long hours of playing with mobile phones or sitting for long periods of time. Muscle fatigue can be relieved or even eliminated by rubbing, tapping or kneading the body with hands or massage devices (massage apparatus, massage chair, electric bed and other massage devices). Compared with manual massage, massage with massage devices is more convenient and private, especially when using home massage devices, there is no need to go out or have physical contact with the masseur.

[0003] The vibration massage device in the related art can only achieve unidirectional massage during massage. For example, a massager electromagnetic vibration micromotor is coaxially provided with a non-magnetic shaft body in the coil, and the two ends of the non-magnetic shaft body are respectively provided with a first magnet and a second magnet, and the opposite magnetic poles of the first magnet and the second magnet are consistent, and the first magnet and the second magnet are axially magnetized. When the coil is energized, the coil assembly generates a magnetic field, and magnetically attracts and repels the first magnet and the second magnet on the non-magnetic shaft body in the axial direction. Since the first magnet and the second magnet are axially magnetized and the same magnetic poles are outward, the magnetic field generated by the coil assembly can drive the non-magnetic shaft body to move in a single axial direction. When the positive and negative poles of the coil are constantly changed, the magnetic field that continuously switches direction drives the non-magnetic shaft body to perform axial reciprocating linear motion, and the column at one end of the non-magnetic shaft body can reciprocate in the through hole of the shell to achieve power drive for massage, thereby achieving linear motion such as percussion massage. The vibration direction of this vibration massage device is single, resulting in a single massage sensation, which cannot meet the massage needs of some users. Utility Model Content

DETAILED DESCRIPTION

[0029] This section will describe in detail the specific embodiments of the present application. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

[0030] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If described, "the second" is only used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of this application, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in this application based on the specific content of the technical solution.

[0033] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0034] See also Figure 1 and Figure 2 The first aspect of the present application provides a massage module that can vibrate in multiple directions to achieve different massage sensations.

[0035] The massage module includes an electromagnetic module and an ornament group. The electromagnetic module includes a coil and a magnetic conductive part. The coil is connected to a power source so that current can be passed through the coil and an electromagnetic field can be generated. The magnetic conductive part can be magnetized under the action of the electromagnetic field to generate magnetic force. There are at least two electromagnetic modules, and the magnetic forces generated by the at least two electromagnetic modules are in different directions. The number of ornament groups is the same as the number of electromagnetic modules and corresponds one to one. Each ornament group is spaced apart from the magnetic conductive part of the corresponding electromagnetic module. Each ornament group includes one or more ornaments. The magnetic force generated by the magnetic conductive part of each electromagnetic module can attract or repel the corresponding ornament group, thereby causing the ornament group to swing back and forth, thereby forming vibration.

[0036] It is understandable that the power supply can be a DC power supply, and the pendulum group can be made to swing back and forth by turning the power supply on and off, thereby forming vibration. For example, the magnetic member can be magnetized under the action of the electromagnetic field generated by the coil, thereby generating a magnetic attraction force, so that the pendulum group swings in the direction close to the magnetic member. When the power supply is turned off, the magnetic member loses the magnetic attraction force, and the pendulum group rebounds under the action of its own elasticity. By turning the power supply on and off, the pendulum group can swing back and forth, thereby forming vibration; for another example, when the pendulum group itself has magnetic force, the direction of the magnetic field can be changed by changing the current direction of the coil. The magnetic member can be magnetized under the action of the electromagnetic field generated by the coil, thereby generating a magnetic repulsion force, so that the pendulum group swings in the direction away from the magnetic member. When the power supply is turned off, the magnetic member loses the magnetic repulsion force, and the pendulum group rebounds under the action of its own elasticity. By turning the power supply on and off, the pendulum group can swing back and forth, thereby forming vibration. The power supply can also be an AC power supply. By switching the current direction of the coil, the magnetic member can attract and repel the pendulum group, so that the pendulum group swings back and forth, thereby forming vibration.

[0037] Since the magnetic forces generated by the at least two electromagnetic modules are in different directions, the magnetic conductive parts of the at least two electromagnetic modules can attract or repel the corresponding pendulum groups to swing back and forth in different directions, thereby achieving vibrations in different directions and further achieving different massage sensations.

[0038] It can be understood that each electromagnetic module can share a power supply to simultaneously control the opening and closing of each electromagnetic module; each electromagnetic module can also be connected to a power supply to control the opening and closing of each electromagnetic module. Among them, the electromagnetic module is turned on when each electromagnetic module starts to drive the corresponding pendulum group to start swinging; the electromagnetic module is closed when each electromagnetic module stops driving the corresponding pendulum group to swing.

[0039] It is worth noting that the “magnetic forces in different directions” in the embodiments of the present application refers to the angle θ∈(0°, 180°) formed between any two magnetic forces, excluding 0° and 180°.

[0040] It can be understood that one or more coils and one or more magnetic conductive parts can be set in an electromagnetic module, and no specific restrictions are made here. The number and positional relationship of the coils and magnetic conductive parts can be set according to actual conditions. For example, an electromagnetic module can be provided with multiple coils and multiple magnetic conductive parts, and the corresponding pendulum group of the electromagnetic module can be provided with multiple pendulums, wherein the number of coils, magnetic conductive parts and pendulums is the same and one-to-one corresponding; for another example, an electromagnetic module can be provided with multiple coils and multiple magnetic conductive parts, and the corresponding pendulum group of the electromagnetic module can be provided with one pendulum, wherein the number of coils and magnetic conductive parts is the same and one-to-one corresponding; for another example, an electromagnetic module can be provided with one coil and one magnetic conductive part, and the corresponding pendulum group of the electromagnetic module can be provided with one pendulum.

[0041] In some embodiments, the number of electromagnetic modules and the number of ornament groups are three, and the three electromagnetic modules are respectively a first electromagnetic module 110 , a second electromagnetic module 120 , and a third electromagnetic module 130 .

[0042] For example, each electromagnetic module is provided with a coil and a magnetic conductive member, and each pendulum member group is provided with a pendulum member. Figure 1 and Figure 2 , the first electromagnetic module 110 ( Figure 1 The first electromagnetic module 110 (not shown) is composed of a first coil 111 and a first magnetic conductive member 112, the second electromagnetic module 120 is composed of a second coil 121 and a second magnetic conductive member 122, and the third electromagnetic module 130 is composed of a third coil 131 and a third magnetic conductive member 132. The three pendulum groups are respectively a first pendulum 210, a second pendulum 220 and a third pendulum 230, and the first electromagnetic module 110 corresponds to the first pendulum 210, the second electromagnetic module 120 corresponds to the second pendulum 220, and the third electromagnetic module 130 corresponds to the third pendulum 230. This is used as an example for explanation.

[0043] Optionally, each swing element comprises a connected fixed portion and a swing portion, the fixed portion and the swing portion have a smooth transition, and each swing portion is provided with a protrusion at a position opposite to the corresponding electromagnetic module. Optionally, the protrusion on each swing portion is provided at one end of each swing portion close to the corresponding fixed portion.

[0044] See also Figure 3 and Figure 4 , the first pendulum 210 includes a first fixed part 211 and a first swinging part 212 connected to each other, the second pendulum 220 includes a second fixed part 221 and a second swinging part 222 connected to each other, and the third pendulum 230 includes a third fixed part 231 and a third swinging part 232 connected to each other. The end of the swinging part (first swinging part 212, second swinging part 222, third swinging part 232) of each pendulum close to the corresponding fixed part (first fixed part 211, second fixed part 221, third fixed part 231) is subjected to the magnetic force of the corresponding electromagnetic module (first electromagnetic module 110, second electromagnetic module 120, third electromagnetic module 130), so that the swinging part of each pendulum can swing. Therefore, when the end of the swinging part of each pendulum close to the corresponding fixed part swings with a smaller amplitude, the end of the swinging part of each pendulum away from the corresponding fixed part can also swing with a larger amplitude, which can play a role of lever amplification, thereby effectively increasing the massage range and improving the massage effect.

[0045] Exemplarily, the first fixed portion 211 extends along the X-axis direction, and the first swing portion 212 extends along the Y-axis direction. The second fixed portion 221 extends along the Y-axis direction, and the second swing portion 222 extends along the X-axis direction. The third fixed portion 231 extends along the Z-axis direction, and the third swing portion 232 extends along the X-axis direction.

[0046] Alternatively, see Figure 2 and Figure 3 , the first electromagnetic module 110 extends along the X-axis direction, and the first magnetic force generated by the first electromagnetic module 110 is parallel to the X-axis, so that the first swinging portion 212 of the first pendulum 210 can swing back and forth along the X-axis direction, thereby generating vibration in the X-axis direction; the second electromagnetic module 120 extends along the Y-axis direction, and the second magnetic force generated by the second electromagnetic module 120 is parallel to the Y-axis, so that the second swinging portion 222 of the second pendulum 220 can swing back and forth along the Y-axis direction, thereby generating vibration in the Y-axis direction; see Figure 2 and Figure 4 The third electromagnetic module 130 extends along the Z-axis direction, and the third magnetic force generated by the third electromagnetic module 130 is parallel to the Z-axis, so that the third swinging portion 232 of the third pendulum 230 can swing back and forth along the Z-axis direction, thereby generating vibration in the Z-axis direction. Among them, the X-axis, the Y-axis and the Z-axis are perpendicular to each other.

[0047] Optionally, the pendulum is made of stainless steel material that can be magnetically attracted, and each electromagnetic module can generate magnetic attraction. Exemplarily, the first pendulum 210, the second pendulum 220 and the third pendulum 230 are all made of stainless steel material that can be magnetically attracted. Of course, the pendulum can also be made of other materials such as magnets, and no specific restrictions are made here. Optionally, the fixed part of the pendulum is a short arm, the swinging part is a long arm, the long arm and the short arm are connected to each other in an L shape, the short arm is fixedly connected to the electromagnetic module, the long arm is suspended, and a protrusion arranged opposite to the magnetic conductive part is provided on the long arm, and the protrusion is close to the connection between the long arm and the short arm. When the power is turned on, the magnetic attraction generated by the magnetic conductive part of each electromagnetic module can attract the corresponding long arm, so that the long arm swings in the direction close to the magnetic conductive part. When the power is turned off, each electromagnetic module loses the magnetic attraction, and the long arm of the pendulum rebounds under the action of its own elasticity. By turning the power on and off, the long arm of the pendulum can swing back and forth, thereby forming vibration.

[0048] From the above content, it can be known that the massage module in the embodiment of the present application can vibrate in three different directions (X-axis direction, Y-axis direction, and Z-axis direction) at the same time, so as to achieve different massage sensations. It can be understood that the magnitude of the magnetic force can be controlled by controlling the magnitude of the current passed through the coil, so that the magnitude of the vibration amplitude of the pendulum can be adjusted, and the greater the magnetic force, the greater the vibration amplitude of the pendulum; the speed of the vibration of the pendulum can be adjusted by controlling the frequency of switching the power supply or the frequency of switching the current direction, and the faster the frequency of switching the power supply or the frequency of switching the current direction, the faster the pendulum vibrates.

[0049] Of course, the setting orientation of each electromagnetic module and the direction of the magnetic force generated by each electromagnetic module can be set according to actual needs and are not specifically limited here.

[0050] Optionally, to ensure the same vibration sensation in each direction and improve the user experience, the magnetic forces generated in each direction are equal in magnitude. Exemplarily, the first magnetic force generated by the first electromagnetic module 110, the second magnetic force generated by the second electromagnetic module 120, and the third magnetic force generated by the third electromagnetic module 130 are equal in magnitude.

[0051] Optionally, each electromagnetic module is provided with a coil and a magnetic conductive member, and the length of each coil is equivalent to the length of the corresponding magnetic conductive member, where the length of the coil refers to the length of the wound coil. Each coil is spirally wound on the outer surface of the corresponding magnetic conductive member, and the spacing between each adjacent two turns of each coil is equal. Optionally, the spacing between each adjacent two turns of each coil can be zero.

[0052] For example, each magnetic conductive member is a rectangular parallelepiped, and the cross section of the rectangular parallelepiped is a square with four corners that are smoothly rounded. This structural setting can avoid 90-degree bends when the coil is wound, which is beneficial to protecting the coil. Of course, each magnetic conductive member can also be cylindrical or other shapes, which are not specifically limited here.

[0053] Optionally, the magnetic conductive member is made of silicon steel material. Of course, the magnetic conductive member can also be made of other materials with magnetic conductive function, and no specific limitation is made here. Exemplarily, the magnetic conductive member is a silicon steel sheet group, and the silicon steel sheet has extremely strong magnetic conductivity. When current is passed through the coil, the silicon steel sheet will generate magnetism.

[0054] Optionally, the first electromagnetic module 110 and the second electromagnetic module 120 have the same length and the same diameter, the length of the third electromagnetic module 130 is half the length of the first electromagnetic module 110, and the diameter of the third electromagnetic module 130 is twice the diameter of the first electromagnetic module 110. It can be understood that the length of the electromagnetic module mentioned here does not include the connection part of the magnetic conductive member mentioned below (such as the connection part 1121 of the first magnetic conductive member), and because the cross section of the magnetic conductive member is a square with four rounded corners, the diameter here refers to the side length of each electromagnetic module.

[0055] According to the calculation formula of Ampere force and magnetic induction intensity, when the currents flowing through the three coils are equal, the above structural arrangement can achieve the equality of the first magnetic force generated by the first electromagnetic module 110, the second magnetic force generated by the second electromagnetic module 120, and the third magnetic force generated by the third electromagnetic module 130. At the same time, the length of the third electromagnetic module 130 is half of the length of the first electromagnetic module 110, which can effectively reduce the space occupancy of the massage module in the Z-axis direction in the embodiment of the present application.

[0056] In some embodiments, the massage module further includes a shell 400 , and the electromagnetic module and the ornament group are both mounted on the shell 400 .

[0057] For example, see Figure 5The housing 400 includes a first part 410, a second part 420 and a third part 430 connected to each other. The first part 410 extends along the X-axis direction. The first part 410 is provided with a first cavity (not shown in the drawings) with an opening along its length direction to place the first electromagnetic module 110. The second part 420 extends along the Y-axis direction. The second part 420 is also provided with a second cavity 421 with an opening along its length direction to place the second electromagnetic module 120. The third part 430 is provided between the first part 410 and the second part 420. The third part 430 is provided with a third cavity 431 with an opening along the Z-axis direction to place the third electromagnetic module 130. The first part 410, the second part 420 and the third part 430 can be integrally formed or can be other detachably connected structures, which are not specifically limited here.

[0058] Optionally, a connecting portion is provided at one end of each magnetic conductive member, and the connecting portion is connected to the housing 400 through the fixing member 300 , so that each electromagnetic module is installed on the housing 400 . Figure 6 FIG. 4 shows a structure in which the first electromagnetic module 110 is connected to the fixing member 300. Figure 8 FIG. 3 shows a structure in which the third electromagnetic module 130 is connected to the fixing member 300 .

[0059] Alternatively, see Figure 7 or Fig. 9 The fixing member 300 includes a cover 310, and a first through hole 311 is provided on the cover 310. The area of ​​the first through hole 311 is equivalent to the cross-sectional area of ​​the corresponding magnetic conductive member, so as to reduce the influence on the magnetic force generated by the electromagnetic module. A side of the cover 310 is provided with a surrounding edge 320, and the surrounding edge 320 can be set on the outer periphery of the connecting portion 1121 of the corresponding magnetic conductive member. Figure 7 Taking the first magnetic conductive member 112 in the example, a second through hole 11211 is provided on the connecting portion 1121 of the first magnetic conductive member 112, and two aligned third through holes 321 are provided on the surrounding edge 320 of the corresponding fixing member 300, and the two third through holes 321 can be aligned with the corresponding second through holes 11211, and the first screw 322 passes through the corresponding second through hole 11211 and the third through hole 321, and the first electromagnetic module 110 can be installed on the corresponding fixing member 300 through the nut 323, and a plurality of fourth through holes 312 are circumferentially provided on the cover body 310 of the fixing member 300, and the fixing member 300 with the first electromagnetic module 110 installed can be fixed to the housing 400 by passing the second screw through the fourth through hole 312. Optionally, the cover body 310 of the fixing member 300 is square, and a fourth through hole 312 is respectively provided at the four corners.

[0060] Optionally, the first fixing portion 211 of the first pendulum member 210 is fixed to the outside of the first portion 410 of the shell 400 by bolts, the second fixing portion 221 of the second pendulum member 220 is fixed to the outside of the second portion 420 of the shell 400 by bolts, and the third fixing portion 231 of the third pendulum member 230 is fixed to the outside of the third portion 430 of the shell 400 by bolts.

[0061] Optionally, four fifth through holes are provided on the fixing portion of each ornament, for bolts to pass through to fix each ornament on the shell 400, and the four fifth through holes are symmetrically arranged in pairs.
