Wherein, when the air bag component 7 is expanded, the massage component 6 is in a working state. When the air bag module 7 is contracted, the massage module 6 is in a storage state.

As shown in fig. 6, in the present embodiment, the airbag module 7 is disposed in the driving module 9. The massage unit 6 is disposed in the airbag unit 7. The massage assembly 6 is provided with at least one massage protrusion. The air bag module 7 is used to drive the massage module 6 closer to or away from the drive module 9. The driving assembly 9 is used for driving the air bag assembly 7 and the massage assembly 6 to rotate.

It should be noted that the massage device of the present invention is not limited to be used in a car comfort system (including a car massage seat), but is also applicable to various massage chairs or various massagers, and the application of the massage device of the present invention is not limited specifically.

Specifically, the massage device is arranged on the chair, and when massage is not needed, the comfort of the chair can be ensured only by keeping the surface of the chair flat; when massage is needed, the massage head needs to enable the surface of the chair to be protruded so as to be pressed against a human body (particularly against the back of the human body from the chair back), and then the massage head can press the human body to massage the human body to a certain extent.

The massage device of the present embodiment switches between a massage state and a storage state by driving the massage unit 6 via the extendable member. When massage is required, the telescopic member is lengthened so that the massage assembly 6 is pushed against the back of the person to perform massage.

The airbag module 7 is disposed in the first transmission 12. The first driving member 24 is used for driving the first transmission member to rotate. In particular, the first drive member 24 is an electric motor. The output end of the first driving member 24 is provided with a screw. The axis of the output end of the first drive member 24 is perpendicular to the axis of rotation of the first transmission member 12.

Preferably, the drive assembly 9 further comprises a second transmission member 11 rotatably arranged in the first housing assembly 8. The second transmission member 11 is a gear. The first driving member 24 is connected to the first transmission member 12 through the second transmission member 11. The second transmission piece 11 and the first transmission piece 12 are in speed reduction transmission. The output ends of the first transmission piece 12, the second transmission piece 11 and the first driving piece 24 are in the same plane.

It will be appreciated that the first transmission member 12 and the second transmission member 11 are spur gears. The axial line of the motor and the first transmission piece 12 are arranged on the same plane, so that the thickness of the massage component 6 and the air bag component 7 is superposed with the diameter of the motor, the thickness of the whole massage device is greatly reduced, and the massage device has good practical significance.

And is transmitted to the first transmission member 12 at a reduced speed by the second transmission member 11.

The second housing 25 is disposed on the first housing 23 for covering at least a portion of the first transmission slot 32.

Preferably, the driving assembly 9 further includes a second magnetic member 13 disposed on the first transmission member 12, and a first magnetic induction member 10 disposed on the first housing assembly 8. The first drive member 24 and the first magnetic induction member 10 can be electrically connected to the control assembly by wires.

Specifically, a first transmission groove 32 is formed in the first housing 23 along the first direction, and a first driving groove 30 is formed in the second direction; the first direction is perpendicular to the second direction. The first driving groove 30 is provided with a through hole communicating with the first transmission groove 32. The through hole is used for a screw rod arranged at the output end of the first driving member 24 to pass through. The second transmission member 11 is rotatably disposed on the first housing 23 via a first support column 29 detachably disposed on the first housing 23. Both side surfaces of the first transmission 12 are rotatably disposed in the first casing 23 via an annular bearing or a slider.

In addition to the above embodiments, in an alternative embodiment of the present invention, the airbag module 7 includes a first telescopic base 21 for engaging the driving module 9, and an airbag body 20 connected between the first telescopic base 21 and the massage module 6. Preferably, the airbag body 20 is a multi-layer airbag. The airbag module 7 further includes a conduit swivel 22 disposed in the airbag body 20. The pipeline rotary joint 22 is used for connecting an external air channel pipeline. The first telescopic seat 21 and the first transmission member 12 are provided with through holes for the pipeline rotary joint 22 to pass through.

It should be noted that in the present embodiment, the first telescopic seat 21, the driving assembly 9 and the first housing assembly 8 are combined together to form a base, and the airbag is disposed on the first telescopic seat 21 in the base. In particular, the air bladder assembly 7 is coupled between the base and the massage assembly 6. Wherein the positioning mechanism is configured to limit the range of movement of the massage assembly 6 relative to the base when the air bag assembly 7 is in the deflated state.

In this embodiment, the pipeline rotary joint 22 is directly mounted on the airbag body 20, so that the pipeline rotary joint has better air tightness performance and can ensure that air leakage does not occur after long-term use. Specifically, the airbag body 20 is fixed on the first telescopic seat 21 in an adhesion manner, so that the airbag body 20 and the massage assembly 6 rotate synchronously in the massage process.

It will be appreciated that the conduit swivel 22 is mounted on the rotational axis of the airbag body 20. So that the one end of the pipe line rotary joint 22 connected to the airbag body 20 and the airbag body 20 are rotated in synchronization. The other end and the air pipe are in a relatively fixed state. Specifically, the pipeline rotary joint 22 is installed on the rotary shaft of the airbag body 20, so that the connection structure of the air tube and the airbag body 20 is simpler and the volume is smaller.

As shown in fig. 5 to 10, in other embodiments, the airbag body 20 is an airbag. The first telescopic bracket 21 is provided with a vent hole 27 communicating with the air chamber of the airbag body 20. The airbag module 7 further includes a conduit swivel 22 disposed in the first telescopic mount 21. The pipeline rotary joint 22 is used for connecting an external air channel pipeline. Preferably, the ventilation aperture 27 is arranged coaxially with the axis of rotation of the first transmission member 12. The vent hole 27 is provided in the first positioning projection 33. The first transmission member 12 is provided with a through hole through which the line swivel 22 passes.

In the present embodiment, the first telescopic base 21 is provided with a vent hole 27; the pipe swivel 22 is installed on the vent hole 27, and the airbag body 20 is adhered to the surface of the first telescopic bracket 21 such that the cavity of the airbag body 20 communicates with the vent hole 27. The pipeline rotary joint 22 is directly locked on the first telescopic seat 21 through fine airtight threads, and is simple to disassemble and assemble.

It can be understood that the vent hole 27 is provided on the rotational shaft of the airbag body 20, so that the pipe rotary joint 22 can perform a function of rotary sealing without a complicated structure, and the volume of the pipe rotary joint 22 is greatly reduced, thereby reducing the volume of the entire massage apparatus.

As shown in fig. 6 and 9, in addition to the above embodiment, in an alternative embodiment of the present invention, the first transmission member 12 is provided with a first positioning groove 28. The first telescopic base 21 is provided with a first positioning projection 33 matched with the first positioning groove 28. The first positioning slot 28 is used for limiting the rotation of the first retractable seat 21 relative to the first transmission member 12.

Specifically, the first positioning groove 28 is cross-shaped. The first positioning protrusion 33 of the first telescopic base 21 is fixed in the first positioning groove 28 by a bolt, so that the first telescopic base 21 and the first transmission member 12 rotate synchronously.

Preferably, the first positioning groove 28 and the first positioning protrusion 33 are formed to be symmetrical about the rotation axis of the first transmission member 12. And, a circular through hole is provided between the first positioning groove 28 and the first positioning projection 33 for the pipe rotary joint 22 to pass through.

In other embodiments, the first positioning protrusion 33 and the first positioning groove 28 may be in a straight structure or other structures, and even the positioning groove only performs a positioning function, and is fixed by a bolt to limit the rotation of the first telescopic base 21 relative to the first transmission member 12.

It can be understood that the first telescopic seat 21 is fixed to the first transmission member 12 by the first positioning protrusion 33 embedded in the first positioning groove 28, so that the portion of the first telescopic seat 21 exposed outside the first transmission member 12 is a thin disk-shaped structure. Thereby greatly reducing the thickness of the massage device.

As shown in fig. 4, 5, 6, 8, 9 and 10, on the basis of the above embodiment, in an alternative embodiment of the present invention, the massage assembly 6 comprises a first massage seat 18 and at least one first massage head 14 formed on the first massage seat 18. Specifically, the first massage head 14 is rotatably disposed on the first massage base 18. Preferably, the massage assembly 6 further comprises a first massage bearing 16 and a first bearing seat 15. The first massage head 14 is rotatably disposed on the first bearing housing 15 via a first massage bearing 16. The first bearing seat 15 is disposed on the first massage seat 18.

Specifically, the number of the first massage heads 14 is two. It can be understood that two first massage heads 14 symmetrically arranged can just apply a certain pressure to the human body, the decrease of the contact area with too small quantity easily causes the increase of the pressure intensity to press the human body to generate pain, and the too large quantity of the first massage heads 14 cannot cause the extrusion due to the too large contact area, thereby failing to generate the massage effect.

The first massage head 14 is rotatably disposed on the first massage seat 18, and can be rotated to a certain degree during massage, thereby preventing the massage head from pulling the seat leather surface and tearing the seat leather surface. And the rotating first massage head 14 can produce a better massage effect.

In an alternative embodiment of the present invention, as shown in fig. 4, 6 and 9, the air bag module 7 can be inflated and deflated to perform a telescopic movement in a predetermined direction. When the air bag component 7 is inflated, the massage component 6 is withdrawn outwards to switch to the working state. When the air bag component is exhausted for pressure relief, the massage component is close to the driving component for resetting so as to be switched to a storage state.

In the present embodiment, the positioning mechanism is configured to limit the moving range of the massage assembly 6 relative to the base by means of magnetic attraction when the air bag assembly 7 is in the retracted state. Specifically, the positioning mechanism includes a first magnetic member 17 disposed on one of the first massage base 18 and the first telescopic base 21. The other of the first massage seat 18 and the first telescopic seat 21 is made of a magnetic substance at least partially to limit the movable range of the massage assembly 6 by means of magnetic attraction when the massage assembly 6 is in the storage state.

Preferably, the first telescopic base 21 is entirely made of a magnetic substance. The first massage seat 18 is made of a non-magnetic substance and is provided with a groove for accommodating the first magnetic member 17. The positioning mechanism includes four first magnetic members 17 disposed on the first massage seat 18.

Specifically, since the air bag is not pressurized, the massage unit 6 is likely to rock back and forth when the vehicle rocks, and there is a possibility of knocking the seat. Therefore, in the present embodiment, four magnetic members are provided on the first massage seat 18; and set up first flexible seat 21 as magnetic material, when first massage seat 18 is close to first flexible seat 21, can fix in the position of being close to first flexible seat 21 by magnetism. Thereby preventing the massage unit 6 from shaking in the stored state.

In other embodiments, the positioning mechanism comprises a resilient clasp provided to the base or massage assembly 6. The elastic buckle is configured to limit the movable range of the massage assembly 6 in the form of a snap when the massage assembly 6 is in a contracted state. Specifically, the positioning mechanism comprises an elastic buckle arranged on the driving component 9 or the first telescopic seat 21 or the first massage seat 18. The elastic buckle is configured to limit the movable range of the massage unit 6 in the form of a snap when the massage unit 6 is in the stored state. Alternatively, the positioning mechanism comprises an electrically controlled lock provided to the base or massage assembly 6. The electrically controlled lock is configured to limit the range of motion of the massage assembly 6 in the form of a limit protrusion when the massage assembly 6 is in a retracted state. Specifically, the positioning mechanism comprises an electrically controlled lock disposed on the driving assembly 9 or the first telescopic base 21 or the first massage base 18. The electrically controlled lock is configured to limit the range of motion of the massage assembly 6 in the form of a limit protrusion when the massage assembly 6 is in the stowed state. The utility model discloses do not injecing positioning mechanism's concrete structure, as long as it can be when the massage subassembly is in the state of accomodating, carry on spacingly to massage subassembly and gasbag subassembly, prevent that it from taking place can.

As shown in fig. 6 and 8, on the basis of the above embodiment, in an alternative embodiment of the present invention, a connecting piece 74 is disposed at one end of the airbag body 20 for connecting the massage assembly 6. The connecting piece 74 is used to connect the massage assembly 6. A connecting tab 74 extends outwardly from the connection perimeter to form the first skirt 26. The massage assembly 6 further comprises a first locking ring 19. The locking ring is sleeved on the massage component 6. The locking ring and the first massage seat 18 are clamped to the first skirt 26 to be fixed to the air bag module 7. Specifically, the first massage head 14 and the magnet are arranged on the first massage seat 18. Therefore, a plurality of through holes are formed in the first massage seat 18. So that the contact area of the first massage seat 18 and the air bag body 20 is greatly reduced. If the fixing is performed only by means of adhesion, the falling-off is likely to occur.
