As further shown in fig. 7 to 10, in one embodiment, the housing has at least a flexible upper portion adapted to the outer flexible cushion 8, and the massage mechanism 1 is disposed at one side of the flexible upper portion. The seat body of the mounting mechanism 3 is embedded in the flexible cushion body 8, so that the telescopic mechanism 2 and the massage mechanism 1 in the mounting mechanism 3 are correspondingly arranged on the flexible cushion body 8, and the massage operation of a user is facilitated. In particular, the seat body of the mounting mechanism 3 at least has a flexible upper part matched with the flexible cushion body 8, the flexible upper part is positioned at the massage use side of a user and is configured into a flexible material with the softness consistent with that of the flexible cushion body 8, the seat body part capable of being contacted with the user is matched with the user to be used to the greatest extent, and in the pressing or impacting process, the flexible upper part can be matched with the flexible cushion body 8 in a cooperation manner to provide buffering and elasticity, so that the influence on the use of the user due to the abrupt surface is avoided, the comfort in use is remarkably improved, and the normal use can be kept due to the emergency.

Wherein, the flexible upper part is preferably a side body 32, and it is equivalent to the softness of the flexible cushion body 8. Correspondingly, the base 31 is configured as a hard bottom plate for being locked in the flexible cushion body 8, and the hard base 31 is more beneficial to the installation and adaptation of the telescopic mechanism 2 thereon. As the name implies, the flexibility in the above is a soft or pliable property, whereas the stiffness of a hard base plate is much greater than that of a flexible structure. Preferably, the side body 32 can be, but not limited to, a flexible material such as cloth or bellows, and can maintain the original rigidity and generate buffering and elastic recovery after being stressed, so as to improve the flexibility of the whole device.

Wherein, the base body is constructed into a cup-shaped structure, the side main body 32 is extended horizontally outwards integrally at the upper end to form a cup rim 321, and the cup rim 321 is used for being attached to the outer end face of the flexible cushion body 8. Thus, the cup-shaped side body 32 forms a cup sidewall structure adapted to be integrated with the base 31 into a single piece by using the processes of gluing, pressing, sewing, etc. In addition, the cup rim 321 extending at the cup rim end is square in structure, so that the contact surface between the side main body 32 and the flexible cushion body 8 is increased laterally, the adhesion strength is improved, the whole massage device is favorably positioned and installed in the flexible cushion body 8, and the rapid disassembly and the stability after installation are realized.

Wherein, the top opening of the installation space is exposed outside the rim 321 of the cup, so as to be suitable for the massage mechanism 1 to move in and out of the corresponding switching position along the opening. The top opening is formed on the side of the side body 32 away from the base 31 and is exposed to the outside to allow the massage part 12 to freely move in and out. The rim 321 is a part of the structure of the side body 32, has the same softness, can be adapted to the external flexible cushion 8, bears the direct pressing of the user during normal use (non-massage work), has stronger connection performance, and does not generate a convex and pungent feeling.

As also illustrated in fig. 5-10, in one embodiment, a vibration reduction mechanism 4 is also included. The vibration damping mechanism 4 is provided in the mounting mechanism 3 to provide a cushioning contact to the massage section 12 during movement. Specifically, the damping mechanism 4 includes a buffer body 41 disposed at the top opening, and the buffer body 41 is a hollow ferrule structure and is fixedly disposed in the top opening. The hollow loop structure allows the massage mechanism 1 to freely enter and exit, and direct contact exists between the massage mechanism 1 and the hollow loop structure, so that vibration impact of the massage part 12 can be reduced, the purposes of vibration reduction and noise reduction are achieved, the massage part 12 in the hidden position is more stably clamped in the buffer body 41 through elasticity after retreating, the switching efficiency of the massage part 12 in the space is improved, and the hidden use purpose is achieved.

Wherein, the upper end side of the buffer body 41 is flush with the top opening, the lower end side thereof at least extends to contact and match with the massage part 12 at the hidden position, and the inner ring side thereof at least can be in interference fit with part of the massage part 12. The cushioning body 41 is sleeved on the top opening end in a flush manner, so that the massage part 12 can be in full contact with the top opening end when entering and exiting, and the efficiency of shock absorption and cushioning is improved. And the assembly and disassembly adaptation of the buffer body 41 at the cup rim 321, the subsequent replacement and maintenance and the like are facilitated. The buffer body 41 is fixed to the opening end of the side body 32 so as to be in buffer contact with the massage part 12.

After the massage part 12 is switched to the working position, the body 11 is at least partially accommodated in the buffer body 41. After the massage part 12 is switched to the hidden position, at least a part of the massage part 12 is accommodated in the buffer body 41. By the configuration mode, in the position switching process, the massage mechanism 1 always has a contact relation with the buffer body 41, so that no matter the massage mechanism is used or hidden inside, the stability can be provided to the massage mechanism 1 by the buffer body 41, the lateral stability of the massage part 12 is obviously improved, the shaking and falling are reduced, and the massage mode is effectively improved.

Wherein, in one embodiment, the damping mechanism 4 further comprises a conical sleeve 42 (shown in fig. 9). The tapered sleeve 42 is disposed at the lower end of the buffer 41, and the inner ring thereof is formed with a slope 421 suitable for guiding the massage mechanism 1, and the slope 421 is inclined inward from the bottom to the top, so as to facilitate the massage unit 12 to be guided and sent out to the working position along the hidden position. The tapered sleeve 42 also has a hollow inner side to allow the massage mechanism 1 to move in and out along the axial direction, and a slope 421 formed on the inner side of the tapered sleeve is inclined downward and expands outward, and is butted with each other at the joint of the tapered sleeve 42 and the buffer body 41 to ensure that the massage part 12 moves in contact with the two inner sides.

Wherein, the massage part 12 is at least partially contacted with the slope 421 after being in the hidden position. The descending depth of the massage part 12 is at least 20mm to ensure that the massage part 12 is not directly contacted with the user after the user is impacted after the user is in the hidden position, so as to generate a sharp feeling and even cause injury to the human body. Correspondingly, the height of the bulge of the massage part 12 is more than 15mm, thereby achieving the best massage effect. In particular, the upper end face of the conical sleeve 42 is higher than the massage part 12 located at the hidden position, so as to ensure that the massage part 12 can directly contact with the slope 421 in the hidden position, and is tightly clamped in the conical sleeve 42, and after being driven by the telescopic mechanism 2, the elastic contact of the conical sleeve 42 to the massage part 12 is released, so as to be freely switched to the working position.

The tapered sleeve 42 and the cushion body 41 are configured as separate members made of the same material. In this embodiment, the material of the cone 42 and the cushion 41 may be foam, noise reduction soft ring, sponge, or elastic sheet. It is preferable to separate the two components separately and to construct the two components as a unitary component in appearance through a joining process which is simple and the addition of the tapered sleeve 42 makes the buffer contact and the guided feed more efficient and significant.

And, the embodiment also provides a vehicle, including the massage seat. The embodiment also provides a mattress and a sofa, and the mattress and the sofa are both provided with at least one massager.

In the above, the massage seat is suitable for the comfort and the safety of a vehicle in use, the requirements of the seat massage function and the collision safety are ingeniously met, the comfort function of the product is improved, the safety level of the product applied to various environments is improved, and the competitiveness of the product can be obviously improved. Moreover, the massage function is added on the premise of ensuring the comfort of the seat, and the massage part 12 of the massage chair does not protrude out of the back of the seat when the massage chair is in a non-massage state, thereby ensuring the comfort of passengers.

As shown in fig. 12 and 13, the present embodiment further provides a method for controlling an anti-injury massage, which is suitable for use in a vehicle with an airbag-supported massage seat. The massage control method comprises the following steps:

s10: receiving an operation instruction, inflating the air bag module 21 to drive the massage mechanism 1 to move close to the user side for massage operation;

s20: according to the driving state and the air pressure information, the air escape valve 6 on the corresponding control air path is opened and closed in real time in an active or passive mode, and the massage mechanism 1 moves to the side far away from the user to carry out avoidance operation by discharging redundant air in the air bag;

s30: after the abnormity is relieved, the air pump 7 is instructed to inflate and compensate to the air bag component 21 so as to drive the massage mechanism 1 to reset to the initial working position.

In the above, by flexibly controlling the inflation and deflation operations of the air bag module 21 on the massage seat, the comfort and safety protection of driving is improved, the comfort of driving and traveling is improved, and the safety performance of the automobile seat is properly realized. When the driving state and the air pressure information are abnormal, the air release valve 6 is correspondingly controlled to actively implement the pressure release operation of the electromagnetic driving mode or passively implement the pressure release operation of the elastic pressing type, so that the massage mechanism 1 at the working position is ensured to move to the side far away from the user in an avoiding way through the contraction of the air bag module 21, the hard touch of the massage mechanism on the user is greatly weakened, the secondary damage of the aggravated abnormal condition on the user is avoided, and the driver and passengers are protected to the maximum extent.

The air release valve 6 is preferably an electromagnetic safety valve structure integrating electromagnetic driving and overpressure automatic pressure release, can realize that an electric control instruction directly controls the air release valve to be actively opened, and can also realize safety protection and pressure limiting protection of an air path by passively starting the air release due to the fact that the pressure of the air path rises to exceed the threshold value of the safety valve.

Specifically, the step S20 described above further includes:

and S21, when the massage control ECU receives the acceleration information or the collision information, the massage control ECU directly controls the air escape valve 6 to actively implement the air escape operation in the electromagnetic driving mode.

In one embodiment, the collision information is acquired by a central control ECU of the vehicle, and the central control ECU of the vehicle is electrically connected with the massage control ECU. It should be mentioned that a plurality of safe collision sensors are installed around the automobile body, and when a strong collision occurs, the central control ECU of the automobile can recognize and calculate, and according to the collision strength, send out a signal to trigger the safety airbag. Meanwhile, a collision signal can be sent to other execution components (such as a massage control ECU) to be realized as an auxiliary instruction of safety protection. And the collision signal is connected with the massage control ECU through a CAN bus by the automobile central control ECU, the massage control ECU sends an instruction to drive the air escape valve 6 to open active air escape, redundant air in the air bag component 21 is discharged, the air bag retracts, the massage mechanism 1 is driven to retract to the cavernous body far away from the user side, and then drivers and passengers are protected to reduce secondary injury.

In another embodiment, after the acceleration of the vehicle exceeds the threshold value during driving, the acceleration sensor generates the acceleration information and feeds the acceleration information back to the massage control ECU directly. Specifically, the acceleration sensor is preferably a multi-axis acceleration sensor, which can sense the attitude and dynamic changes of an object in three-dimensional space, sense physical changes such as angles and accelerations, and determine the acceleration state of the vehicle. Therefore, the motion information of the motion posture and the motion information of the speed of the automobile are monitored in real time through the multi-axis acceleration sensor, when the state of the automobile is greatly changed, and the acceleration is more than 1g through algorithm optimization, the massage control ECU sends an instruction to drive the air escape valve 6 to open active air escape.

In a preferred embodiment, the collision information of the driving state is directly electrically connected with the air escape valve 6 through the vehicle central control ECU in a CAN bus connection mode. When the automobile has abnormal collision, a collision signal is sent out and directly fed back to the air escape valve 6 through the automobile central control ECU, the air escape valve 6 is driven to be actively opened, and redundant gas in the air bag assembly 21 is discharged.

Specifically, the above step S20 further includes:

s22: when the air pressure sensor acquires that the air pressure information in the air bag is larger than a preset value, the air escape valve 6 is controlled by the massage control ECU to actively implement the pressure relief operation in an electromagnetic driving mode.

Wherein, the air bag module 21 leads to the air pressure in the air bag module 21 to rise due to abnormal collision or extrusion in the operation process of supporting the massage mechanism 1, when the air pressure sensor detects that the pressure is greater than the preset value, the active air release after the air release valve 6 is opened is directly implemented through the massage control ECU, and the redundant air in the air bag module 21 is discharged.

Specifically, the step S20 described above further includes:

s23: when the internal pressure of the air bag is larger than the bearable range of the air escape valve, the air pressure in the air path directly acts on the air escape valve 6 to enable the air escape valve to passively implement elastic pressing type pressure relief operation.

When the pressure of the air path is larger than the bearable threshold range of the air escape valve 6, the passive air escape is opened in a mode that air presses the valve rod, and redundant air in the air bag assembly 21 is further discharged. Therefore, when massage control is implemented in the driving process, the control mode is realized in a targeted and efficient cooperation mode no matter collision or abnormal air pressure or other phenomena occur, multi-path pressure relief control is ensured, and the purpose of preventing injury is achieved.

In addition, regarding the air pressure balance compensation manner of step S30, specifically, the massage control ECU and the air pressure sensor cooperate to implement pressure monitoring on the air bag module 21, and the air pump 7 is turned off (the air inlet valve is closed) to keep the air pressure in the air bag module 21 constant when the air pressure thereof reaches the optimum working pressure. When the air pressure sensor senses that the air pressure of the air bag component is insufficient during normal operation (non-abnormal occurrence), the air pump 7 is opened in a compensating mode (the air inlet valve is opened) to inflate the air bag component 21, and air pressure balance is achieved in an optimal state suitable for massage operation.

In one embodiment, specifically, the method further comprises:

s40: when receiving the abnormity, and the abnormity is still not stopped after the user triggers the massage mechanism 1 to extrude the air bag component 21 to retreat to the first safe height, the air escape valve 6 of the control air path is actively or passively opened to discharge the redundant air in the bag until the massage mechanism 1 retreats to the second safe height;

s50: controlling the air escape valve to close, and indicating the air pump 7 to inflate and compensate until the massage mechanism 1 rises back to the preset bump height after the abnormity is confirmed to be finished;

s60: after a stop signal for finishing the massage is acquired, the air pump 7 is controlled to suck air so as to recycle the air in the air bag component 21 into the air pump in a negative pressure mode, so that the air bag component 21 contracts to drive the massage mechanism 1 to descend to a preset concave height so as to retreat and sink to a hidden position.

Specifically, the received operation instruction is to control the air pump 7 to inflate the air bag module 21 after acquiring a start signal for starting massage, so as to lift the massage part 12 to a working position with a preset protrusion height to perform massage operation.

And, the preset height of the projection is preferably 15mm or more. The first safety height is 20-25mm, which is the degree of adaptive flexible cushioning of the multi-layer airbag body 211 of the airbag module 21 after being pressed. The second safety height is-10-0 mm, which is the retraction height of the air bag module 21 after pressure relief. The height of the massage part 12 at the hidden position is preferably-20 mm based on the outer side surface of the flexible cushion body 8.

It is apparent that after the massage part 12 has been cushioned to the first safety level, there is no need to unload the excess air to safely protect the user if the impact has ceased. Often, due to factors such as inertia or strong collision accidents, the safety air leakage treatment needs to be performed to further improve the safety, so that an noninductive distance exists between the user and the massage part 12 at the second safety height, and secondary damage or aggravation of extrusion degree is avoided.

Correspondingly, the preset depression height is preferably-20 mm or less. In the above, the massage part 12 at the second safety height is also at a recess height therein, which is higher than the preset recess height. After the collision happens, the massage part 12 hidden in the cushion body can obviously be prevented from or delayed from being in direct contact with the user under the protection of the flexible cushion body 8, and is still in a massage working state, so that the subsequent air pressure compensation mode is more facilitated at the second safety height.

It should be noted that the position of the massage part 12 is switched between the working position and the hidden position, which is described in the above-mentioned massage device and is not described in detail. In addition, the massage part 12 can directly perform massage operation by at least one massage head structure protruding therefrom, or the motor therein can be powered on to start rotating to drive the eccentric wheel to rotate, so as to generate eccentric vibration, and then the vibration is transmitted to the human body part (such as the back) through the support of the body 11 and the air bag component 21, so as to realize powerful vibration massage. The massage intensity can be further regulated by adjusting the voltage applied to the motor, or can be directly regulated by the direct lifting operation of the air bag assembly 21 after inflation. The massage part 12 can also have a heating function, thereby improving the function diversity of the massage device.

As shown in fig. 12 and 14, the present embodiment further provides a massage control device, which is applied to a lumbar support position of a massage seat of an automobile to massage the waist of a driver or a passenger. The massage control device includes the massage mechanism 1, the air bag module 21, and an air path (see the description of the massage device for the specific air path configuration). The vehicle comprises a massage seat and a massage device arranged on the massage seat.
