[0041] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] In the description of this utility model, it should be understood that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] like Figures 1 to 3 As shown, in one embodiment, the massage device 10 includes a massage unit 1, a drive unit 2, and a support unit 3; the massage unit 1 and the drive unit 2 are mounted on the same side of the support unit 3; the drive unit 2 is used to drive the massage unit 1 to rotate around a first axis, so that the massage unit 1 can massage the target; the support unit 3 can be inflated and deflated, and when the support unit 3 is inflated, it can expand along the extension direction of the first axis so as to drive the drive unit 2 and the massage unit 1 to move in a direction away from the support unit 3.

[0045] In this embodiment, in addition to massaging the target by inflating and deflating the support unit 3, the massage unit 1 can be rotated by the drive unit 2 to perform kneading massage on the target, thereby improving the massage effect of the massage device 10.

[0046] In addition, mounting the massage unit 1 and the drive unit 2 on the same side of the support unit 3 not only facilitates the assembly of the massage device 10, but also improves the kneading massage effect on the target.

[0047] Furthermore, "the support unit 3 can be inflated and deflated" means that the support unit 3 can be inflated and deflated. Both inflation and deflation operations can be performed using appropriate inflation / deflation devices.

[0048] "The drive unit 2 and the massage unit 1 move in the direction away from the support unit 3" can mean that: in the extension direction of the first axis, the drive unit 2 and the massage unit 1 are both located on one side of the support unit 3, and when the support unit 3 is inflated, it can drive the drive unit 2 and the massage unit 1 to move in the direction from the support unit 3 to the drive unit 2.

[0049] refer to Figure 1 The right-hand view shows support unit 3 in a retracted or uninflated state; see reference. Figure 2 Right-hand view, showing support unit 3 in an expanded state. (Reference) Figure 2 The circular arrow in the left-hand view can indicate the direction of rotation of the massage unit 1 around the first axis.

[0050] like Figure 4 As shown, in one embodiment, the massage unit 1 includes a massage head 11 and a rotor 12, with the rotor 12 mounted on the massage head 11; the drive unit 2 includes a stator 21, which is mounted on the support unit 3; the stator 21 can drive the rotor 12 by magnetic force so that the rotor 12 drives the massage head 11 to rotate around a first axis.

[0051] In this embodiment, integrating the rotor 12 onto the massage head 11 and mounting the stator 21 onto the support unit 3 simplifies the structure of the massage device 10 and helps to reduce the size and weight of the massage device 10.

[0052] For example, compared to directly using a rotary motor to drive the massage unit 1 to rotate around the first axis, the configuration in this embodiment can eliminate the need for structures such as the housing of the rotary motor.

[0053] In addition, the configuration of this embodiment can reduce the size of the massage device 10, facilitate multi-point arrangement, and improve the massage effect.

[0054] Furthermore, the axis of stator 21 can be the first axis.

[0055] In the actual product, the rotor 12 can be a structure independent of the massage head 11. In this case, the rotor 12 can be fixed to the massage head 11 by means of snap-fit ​​or other means. For example, it can be fixed in the receiving hole 13 of the massage head 11 (see the description below); or, the rotor 12 can be integrally set with the massage head. In this case, the entire massage unit 1 can also be called a rotor. For example, the rotor 12 can be a magnetic or similar magnetic structure embedded in the massage head 11.

[0056] In one embodiment, the rotor 12 is a permanent magnet assembly, and the stator 21 is an electromagnetic assembly that generates a magnetic field when energized. During operation, the stator 21 can be energized to generate a magnetic field opposite to that of the rotor 12, thereby driving the rotor 12 to rotate.

[0057] The permanent magnet component and the electromagnetic component can both be existing technologies, and the way the two work together to drive the rotor 12 to rotate is also existing technology.

[0058] like Figure 4As shown, in one embodiment, the massage head 11 has a receiving hole 13 on the side facing the support unit 3; the rotor 12 and the stator 21 are both located within the receiving hole 13. In this case, the massage head 11 can protect the rotor 12 and the stator 21, improving their working performance and service life.

[0059] Among them, the receiving hole 13 is a blind hole, which extends along the extension direction of the first axis.

[0060] In addition, in this embodiment, the massage head 11 can also be regarded as the housing of the rotary motor.

[0061] The massage head 11 can be configured into different shapes according to actual needs.

[0062] In one embodiment, the rotor 12 includes a plurality of magnetic blocks, each connected to the wall of the receiving hole 13 and arranged sequentially around a first axis. This facilitates the production and assembly of the rotor 12. Here, "a plurality of" refers to two or more, and the meaning of the term "a plurality of" is the same in all embodiments and will not be repeated hereafter.

[0063] In actual production, the magnetic block and the massage head 11 can be integrally molded by injection molding or other methods.

[0064] Of course, in some scenarios, after the massage head 11 is prepared, multiple mounting grooves are provided on the inner surface of the hole wall of its receiving hole 13. The mounting grooves correspond one-to-one with the magnetic blocks, and each magnetic block is embedded in its corresponding mounting groove.

[0065] In addition, the magnetic block can be a permanent magnet, or it can be a rubber magnetic strip, etc.

[0066] In addition, each magnetic block can be evenly arranged around the first axis.

[0067] In one embodiment, each magnet is surrounded on the outside of the stator 21.

[0068] like Figure 4 As shown, in one embodiment, the stator 21 has a mounting hole 22 extending along the extension direction of the first axis; the bottom surface of the receiving hole 13 is provided with a rotating shaft 14, which passes through the mounting hole 22 and can rotate relative to the stator 21 around the first axis within the mounting hole 22. This makes the massage head 11 and the stator 21 fit more stably, which helps to avoid friction and collision between the stator 21 and the rotor 12.

[0069] Alternatively, the rotating shaft 14 can be a cylindrical structure, and its axis is the first axis.

[0070] like Figure 3 and Figure 4As shown, in one embodiment, the massage device 10 further includes a bearing 4, with a rotating shaft 14 embedded in the inner ring of the bearing 4 and the outer ring of the bearing 4 embedded in the mounting hole 22. This can further improve the stability of the fit between the massage head 11 and the stator 21.

[0071] The rotating shaft 14 and the inner ring can be interference-fitted, and the outer ring and the mounting hole 22 can also be interference-fitted. Moreover, the rotating shaft 14, the bearing 4, and the mounting hole can be coaxially arranged.

[0072] In addition, the number of bearings 4 can be one or more.

[0073] When there are multiple bearings 4, each bearing 4 is arranged sequentially along the extension direction of the first axis. Figure 3 and Figure 4 In the example shown, there are two bearings 4.

[0074] In one embodiment, the mounting hole 22 is a stepped hole with a stepped surface, and the outer ring of the bearing 4 can abut against this stepped surface. This facilitates the installation of the bearing 4.

[0075] like Figure 4 As shown, in one embodiment, the mounting hole 22 passes through the stator 21 along the first axis; the rotating shaft 14 passes through the stator 21 through the mounting hole 22; the stator 21 is provided with a first limiting structure, and the rotating shaft 14 is provided with a second limiting structure; the first limiting structure can cooperate with the second limiting structure to prevent the rotating shaft 14 from coming out of the mounting hole 22 in a direction away from the support unit 3. This arrangement can make the massage head 11 more firmly connected to the stator 21.

[0076] "The first limiting structure can cooperate with the second limiting structure to prevent the rotating shaft 14 from coming out of the mounting hole 22 in the direction away from the support unit 3" can mean that when the massage head 11 moves relative to the stator 21 in the direction from the support unit 3 to the drive unit 2, the first limiting structure can abut against the second limiting structure in order to prevent the massage head 11 from continuing to move in that direction and prevent the rotating shaft 14 from completely exiting the mounting hole 22.

[0077] When the rotating shaft 14 and the stator 21 are connected by the bearing 4, the first limiting structure can be the inner ring of the bearing 4, and the second limiting structure can be the snap ring 5 set on the rotating shaft 14.

[0078] At this time, the side of the rotating shaft 14 is provided with a slot, the retaining spring 5 is inserted into the slot and protrudes outward from the side of the rotating shaft 14.

[0079] like Figure 3 and Figure 4As shown, in one embodiment, the stator 21 includes a coil winding 211 and a circuit board 212; the circuit board 212 is connected to the support unit 3; the coil winding 211 is electrically connected to the circuit board 212 and is located on the side of the circuit board 212 away from the support unit 3.

[0080] When the coil winding 211 is energized, the coil winding 211 can generate a magnetic field, which can then drive the rotor 12 to rotate.

[0081] In addition, the circuit board 212 can also be used to support and fix the coil winding 211, which facilitates the installation of the coil winding 211.

[0082] In addition, when the coil winding 211 is electrically connected to the circuit board 212, it can be powered through the circuit board 212 during operation. That is, the external power supply device is electrically connected to the circuit board 212. At this time, the power supply device supplies power to the coil winding 211 through the circuit board 212.

[0083] Furthermore, by placing the coil winding 211 on the side of the circuit board 212 away from the support unit 3, the operation of the coil winding 211 can be prevented from being adversely interfered with by the support unit 3.

[0084] Meanwhile, the aforementioned magnetic blocks all surrounding the outside of the stator 21 actually means that each magnetic block surrounds the outside of the coil winding 211. The axis of the stator 21 is the axis of the coil winding 211.

[0085] In one embodiment, the mounting hole 22 is actually provided on the coil winding 211.

[0086] The coil winding 211 includes a silicon steel sheet and a coil wound on the silicon steel sheet. The mounting hole 22 is actually provided on the silicon steel sheet.

[0087] like Figure 3 and Figure 4 As shown, in one embodiment, the massage device 10 further includes a wiring harness box 6 and conductive wires. The conductive wires are wound inside the wiring harness box 6, with one end extending out of the box to electrically connect to the drive unit 2, and the other end extending out of the box to electrically connect to the power supply device. When the support unit 3 is inflated, it can unwind the conductive wires to increase the length of the conductive wires extending out of the wiring harness box 6. When the support unit 3 is deflated, the wiring harness box 6 can rewind the conductive wires to reduce the length of the conductive wires extending out of the box. This allows the conductive wires to be arranged more neatly, preventing interference with the operation of the massage unit 1.

[0088] The wire harness box 6 has a receiving cavity, and a wire passage is formed on the surface of the receiving cavity. The conductive wire is located in the receiving cavity and extends out of the receiving cavity from the wire passage. The extension of the conductive wire out of the receiving cavity means that it extends out of the wire harness box 6.

[0089] In addition, the cavity is equipped with components such as coil springs to enable the winding and unwinding of the conductive wire.

[0090] Moreover, the wiring harness box 6 can be installed using existing technology.

[0091] In addition to electrically connecting the drive unit 2 and the power supply device, the conductive wires can also be used to electrically connect the drive unit 2 and other external components. For example, the conductive wires include multiple wires arranged side by side, one wire can electrically connect the drive unit 2 and the power supply device, and another wire can electrically connect the drive unit 2 and the control device, wherein the control device can control the operation of the massage device 10.

[0092] Furthermore, when the drive unit 2 includes a stator 21, the conductive wires are actually electrically connected to the stator 21.

[0093] like Figure 4 As shown, in one embodiment, when the stator 21 includes a coil winding 211 and a circuit board 212, the circuit board 212 is connected to the side of the harness box 6 away from the support unit 3; the coil winding 211 is connected to the side of the circuit board 212 away from the harness box 6 and is electrically connected to the conductive wire through the circuit board 212.

[0094] That is, the wire harness box 6 is located between the circuit board 212 and the support unit 3, and the circuit board 212 is located between the coil winding 211 and the wire harness box 6. At this time, in the extension direction of the first axis, the support unit 3, the wire harness box 6, the circuit board 212 and the coil winding 211 are arranged in sequence.

[0095] like Figure 3 As shown, in one embodiment, the support unit 3 is provided with a first wire-passing hole 31, the wire harness box 6 is provided with a second wire-passing hole 61, and the circuit board 212 is provided with a third wire-passing hole 213. In the extending direction of the first axis, the first wire-passing hole 31 penetrates the support unit 3, the second wire-passing hole 61 penetrates the wire harness box 6, and the third wire-passing hole 213 penetrates the circuit board 212. Conductive wires pass through the first wire-passing hole 31, the second wire-passing hole 61, and the third wire-passing hole 213. This reduces the exposed conductive wires and avoids interference with the operation of other components.

[0096] Specifically, for the wire harness box 6, its wire passage is formed on the inner surface of the second wire passage hole 61. After the conductive wire extends out from the wire passage, it passes through the second wire passage hole 61.

[0097] In addition, after assembly, in the extension direction of the first axis, the first wire hole 31, the second wire hole 61 and the third wire hole 213 are opposite each other. That is, in the orthographic projection of a plane perpendicular to the first axis, the projections of the first wire hole 31, the second wire hole 61 and the third wire hole 213 have an overlapping area, and this overlapping area does not refer to the edge line of the projection.

[0098] Furthermore, after assembly, the rotating shaft 14 can also extend into the first wire-passing hole 31; or, the rotating shaft 14 can also extend into the first wire-passing hole 31 and the second wire-passing hole 61; the rotating shaft 14 can also extend into the first wire-passing hole 31, the second wire-passing hole 61 and the third wire-passing hole 213.

[0099] like Figure 1 and Figure 2 As shown, in one embodiment, the massage device 10 further includes a base plate 7, on which the support unit 3 is mounted. Furthermore, in the extending direction of the first axis, the drive unit 2 and the massage unit 1 are located on the side of the support unit 3 opposite to the base plate 7.

[0100] This makes it convenient to install and use the massage device 10 on other devices.

[0101] In addition, each of the massage unit 1, drive unit 2 and support unit 3 is provided with at least one, and they correspond one to one.

[0102] When multiple massage units 1, drive units 2, and support units 3 are provided, each support unit 3 is installed on the base plate 7 and spaced apart from each other; the drive unit 2 is installed on its corresponding support unit 3, and the massage unit 1 is installed on its corresponding drive unit 2. This can improve the massage effect of the massage device 10.

[0103] In one embodiment, the support unit 3 may be an object such as an airbag as in the prior art.

[0104] In addition, when the support unit 3 is an airbag, the support unit 3 can be a single-layer airbag or a multi-layer airbag.

[0105] During the massage, the pressure inside the support unit 3 can be controlled to adjust its firmness and thus the massage intensity.

[0106] At this time, an air pressure sensor can be installed in the air circuit that supplies air to the support unit 3 so as to detect the air pressure inside the support unit 3 and thus facilitate the control of its softness and hardness.

[0107] like Figure 5 As shown, this utility model embodiment also provides a seat 100, which includes a seat body 20 and a massage device 10 described in any of the above embodiments; the massage device 10 is installed on the seat body 20 and is used to massage a target sitting on the seat body 20.

[0108] The seat 100 can be a massage chair or a vehicle seat, etc.

[0109] like Figure 6As shown, in one embodiment, the seat body 20 is provided with a receiving space 201, and the receiving space 201 forms an opening on the sitting side surface of the seat body 20; the massage device 10 is disposed in the receiving space 201; when the support unit 3 is inflated, the massage unit 1 can extend out of the receiving space 201 from the opening; when the support unit 3 is deflated, the massage unit 1 can enter the receiving space 201 from the opening.

[0110] When a massage is needed, the support unit 3 can be inflated, causing the massage unit 1 to extend out of the receiving space 201, thus allowing the target sitting on the seat 100 to receive a massage. When the target is sitting normally, the massage unit 1 can be inserted into the receiving space 201 to prevent the target from contacting the massage unit 1, thus avoiding any foreign object or hard object sensation and improving comfort during normal sitting.

[0111] Among them, the seating side surface is the A-side of the seat body 20. The seat body 20 typically includes a seat cushion 202 and a backrest 203. The upper surface of the seat cushion 202 and the front surface of the backrest 203 can both be regarded as the seating side surface of the seat 100.

[0112] In addition, when the support unit 3 is deflated, the massage unit 1 can be completely inserted into the receiving space 201 so that it does not protrude outward from the opening.

[0113] Furthermore, when there are multiple massage units 1, there are also multiple openings, and each opening corresponds to a massage unit 1. The massage unit 1 extends out of the receiving space 201 from its corresponding opening.

[0114] like Figure 5 As shown, in one embodiment, the massage device 10 is mounted on the backrest 203 of the seat 100. This allows for massage of the back of the person sitting on the seat body 20.

[0115] At this time, the accommodating space 201 is mainly set on the foam pad of the backrest 203.

[0116] In addition, after assembly, the base plate 7 can be connected to the springs of the seat cushion or backrest.

[0117] This utility model embodiment also provides a vehicle, which includes the seat 100 described in any of the above embodiments.

[0118] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0119] In other embodiments, the rotor 12 may be an electromagnetic component and the stator 21 may be a permanent magnet component. In this case, to avoid interference with the power supply wires during rotation, it can be electrically connected to external wires via conductive slip rings or the like. The specific configuration of this method can also employ existing technology. Alternatively, both the rotor 12 and the stator 21 may be electromagnetic components.

[0120] In other embodiments, the first limiting structure may be a structure of the stator 21 itself, and the second limiting structure may be a stop connected to the rotating shaft 14, etc.

[0121] In other embodiments, the magnetic block may also be disposed on the side of the rotating shaft 14 and located within the mounting hole 22.

[0122] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
