[0002] At present, the widely used percussion massage mechanical structures on the market generally have complex mechanisms and relatively large thicknesses. When not in use, the protruding massage arms will cause obvious foreign body sensations, affecting the comfort of the back, limiting the usage scenarios of the massage movement, and causing space waste. At the same time, most of the massage arms are made of engineering plastics or metal brackets, and the height of the percussion heads cannot be adjusted, and the massage intensity cannot be adjusted according to the needs of the massage device or the individual experience of the user, affecting the comfort.

[0003] In addition, the existing massage arms are generally placed above the motor, resulting in a relatively large thickness of the massage movement; or the massage arms are placed on both sides of the motor, and in order to achieve the massage effect, the massage arms need to extend a large distance above the movement, resulting in the inability to adjust the height of the percussion heads and poor massage comfort. In order to adjust the height of the percussion heads, a complex structure needs to be designed, which will result in a relatively large thickness of the movement and is not conducive to use in scenarios such as automobile seats and sofas, limiting the usage scenarios of the massage device.

Detailed implementation manners

[0043] Embodiment 1

[0044] As Figures 1 to 13 shown, this embodiment provides a thin massage movement mechanism, including a base 1, a driving component, and a massage component; the massage component includes a percussion massage head 5 and a connecting plate 4, and the percussion massage head 5 is configured to be switchable between a protruding state close to the user and a retracted state away from the user; the connecting plate 4 is pivotally connected to the base 1 so as to swing around its middle fulcrum for a seesaw movement, and it has a first end 41 and a second end 42 arranged on the left and right sides of the middle fulcrum, and at least one of the first end 41 and the second end 42 is attached with the percussion massage head 5; wherein, the connecting plate 4 is in transmission connection with the driving component, and only when the percussion massage head 5 is in the protruding state can the connecting plate 4 drive the percussion massage head 5 to perform a percussion massage action, while when the percussion massage head 5 is in the retracted state, the maximum thickness dimension of the massage movement mechanism can be reduced.

[0045] By designing the structure of the connecting plate 4, the percussion massage head 5 can be flexibly switched between the protruding state and the retracted state. When not performing massage, the percussion massage head 5 is in the retracted state, effectively avoiding the foreign body sensation brought by the protrusion of the traditional massage arm, thus improving the comfort. In addition, the height and massage force of the percussion massage head 5 can both be adjusted, and can be personalized according to different users or different massage needs, further enhancing the use experience. And the symmetrical design on both sides of the connecting plate 4 also ensures uniform force and extends the service life of the movement mechanism.

[0046] Furthermore, in combination with Figure 3a and Figure 3b shown, the relationship between the thickness H1 of the percussion massage head 5 in the protruding state and the thickness H2 in the retracted state is H1≥5H2. In this way, when the percussion massage head 5 is in the protruding state, its height can be ensured for percussion massage of the user. When the percussion massage head 5 is in the retracted state, its thinning is ensured, thereby reducing the maximum thickness dimension of the massage movement mechanism. In this way, when the user leans against the backrest, the foreign body sensation generated by the percussion massage head 5 on the user can be reduced, making the user lean more comfortably; preferably, H1>80mm. In the actual use process, the user can flexibly adjust the height of the percussion massage head 5 in the protruding state according to their own needs. For example, the thickness H1 of the percussion massage head 5 in the protruding state is 90mm, 100mm, 120mm, etc.

[0047] Of course, in other embodiments, while ensuring the height requirement of the percussion massage head 5 in the extended state, the thickness H2 of the percussion massage head 5 in the retracted state is greater than 25 mm. In this way, both the height and the percussion force of the percussion massage head 5 in the extended state can be ensured, and the lightness of the percussion massage head 5 in the retracted state can be ensured, thereby reducing the overall thickness of the massage movement. Preferably, the thickness of H2 can be 30 mm, 35 mm, 40 mm, etc., but it should be noted that the size of H2 does not exceed 80 mm.

[0048] Combination Figures 1 to 5 As shown, the percussion massage head 5 includes an airbag 51 and a percussion head 53 fixed to the top of the airbag 51, the bottom of the airbag 51 is fixed to the connecting plate 4, and the bottom of the airbag 51 has an inflation port for exchanging with external airflow; wherein, the airbag 51 includes a plurality of sub-air bags, and an air inlet channel is provided between any two adjacent sub-air bags so that the airflow flows in the plurality of sub-air bags, and the airbag 51 is connected to an inflation device (not shown in the figure). When the inflation device is inflated, the airbag 51 expands and lifts up to raise the percussion head 53 for the convenience of the user to perform massage, and when massage is not required, the airbag 51 is deflated so that the plurality of sub-air bags are pressed and stacked in sequence on the connecting plate 4 to reduce the height, thereby preventing the percussion head 53 from being too high to affect the user's comfort when the percussion massage head 5 is not required for massage. The percussion massage head 5 is suitable for expanding to form a massage piece when inflated, which means that the percussion massage head 5 raises the percussion head 53 after being inflated to facilitate massage; of course, it can also be used as a massage piece for massage in an uninflated state. In this embodiment, when the massage movement is used, the airbags 51 at both ends of the connecting plate 4 are inflated while the motor 2 is started, so that the percussion head 53 is raised. When the height of the percussion head 53 is suitable, the inflation can be stopped; when the height of the percussion head 53 is too high or the intensity is too strong, the height can be lowered by deflation; when the height of the percussion head 53 is too low or the massage intensity is weak, the inflation can continue, so as to achieve the best massage effect that varies from person to person. When the massage function is not used, the airbag 51 is deflated to shrink the airbag 51, which saves space. At the same time, the device is not limited to the number of layers of the sub-airbags, and the number of layers of the sub-airbags can be increased or decreased according to the scene to be realized and the massage product to be adapted. Furthermore, a pressing plate 52 is provided on the airbag 51. The pressing plate 52 can be provided between two adjacent sub-airbags, and of course can also be provided at the outer edge of the sub-airbag 51. The utility model is not limited to this. The pressing plate 52 is made of metal material to increase its weight so that the sub-airbag 51 can be retracted in an orderly manner after being deflated, which is convenient for storage.

[0049] As a preferred embodiment, in order to make the thickness of the percussion massage head 5 in the retracted state thinner, the percussion head 53 is configured as a soft elastic structure, specifically including a connecting portion 531 and a soft massage protrusion 532, wherein the connecting portion 531 is fixed to the top of the airbag 51, and an air port is connected between the soft massage protrusion 532 and the airbag 51; thus, when the airbag 51 is deflated and in the retracted state, the gas inside the percussion head 53 will also be discharged, so that the percussion head 53 is configured to be squeezed and deformed to reduce the foreign body sensation on the user's back. When the inflating device inflates the airbag 51, the inside of the percussion head 53 will also swell under the filling of gas, so as to perform percussion massage on the human body. Furthermore, a cavity is formed between the soft massage protrusion 532 and the connecting portion 531, and the cavity can be filled with porous materials, such as sponge, velvet and the like; and the material of the percussion massage head 53 is any one of TPU film, PU film, rubber, TRITAN, or soft silicone, which can ensure that the soft massage protrusion 532 maintains a predetermined shape in the inflated state to ensure the percussion effect of the percussion head 53.

[0050] Furthermore, combined with Figure 4 As shown, the connecting portion 531 is constructed as an annular portion with the same shape and size as the edge of the airbag 51, so as to facilitate the combination and fixation of the two. The connecting portion 531 can be fixed by bonding, welding, screws, etc.; in addition, the soft massage protrusion 532 is designed to be smaller in size to reduce the contact area with the human body, so that the soft massage protrusion 532 has more concentrated force and better knocking effect when tapping; preferably, the soft massage protrusion 532 is any one of a hemispherical structure, a vertebral structure or a columnar structure.

[0051] In this embodiment, the percussion massage head 5 adopts a design combining an airbag 51 and a percussion head 53, and inflation and deflation are achieved through an inflating device, thereby adjusting the percussion force and touch. This design not only improves the flexibility of massage, but also allows users to choose different massage modes according to their own needs, thereby enhancing the diversity and interest of massage. In actual use, the number of layers of the airbag 51 can be increased or decreased according to the thickness of the massage device, solving the problem that the height of the percussion head 53 cannot be adjusted. At the same time, the massage force can also be adjusted by the inflation time of the airbag 51 to meet the user's massage comfort for the human body and achieve a satisfactory massage effect.

[0052] The connecting plate 4 is configured as a seesaw, which can be electrically moved up and down around its center, so that the percussion massage heads 5 on both sides alternately percuss the user's body up and down. Specifically, the percussion massage heads 5 are fixedly connected to the first end 41 and the second end 42 on the left and right sides of the connecting plate 4, and the first and second ends 42 are both sunken relative to the middle of the connecting plate 4, that is, the upper planes of the first end 41 and the second end 42 are lower than the height of the top surface of the connecting plate 4, so that the percussion massage heads 5 can further reduce the thickness of the entire massage movement in the retracted state; further, the first and second ends 42 on both sides of the connecting plate 4 are provided with through holes, so that the inflation nozzle 51a at the bottom of the airbag 51 can pass through the through hole to communicate with the external inflation device, so as to further reduce the thickness of the massage movement.

[0053] Continue to combine Figure 4 As shown, the base 1 is formed with a mounting body 11 for mounting the connecting plate 4, the mounting body 11 is provided with a mounting hole 12, the middle of the connecting plate 4 is provided with a first connecting hole 43 and a second connecting hole 44, and the connecting plate 4 is fixed on the base 1 by setting a first pivot 61 passing through the first connecting hole 43 and the mounting hole 12, so that the connecting plate 4 can be swung left and right with the first pivot 61 as a fulcrum. Preferably, the first pivot 61 is a bolt shaft, which can not only fix the connecting plate 4 on the base 1, but also enable the connecting plate 4 to swing left and right around the base 1.

[0054] The driving assembly includes a motor 2 and an eccentric mechanism 3. A mounting groove suitable for fixing the motor 2 is formed on the base 1. The motor 2 and the connecting plate 4 are arranged side by side on the base 1 to reduce the thickness of the massage movement; the connecting plate 4 is connected to the motor 2 through the eccentric mechanism 3. Specifically, the eccentric mechanism 3 includes a first eccentric wheel 31, a bearing 36 and a cam 39. The first eccentric wheel 31 is connected to the output shaft of the motor 2. A bearing 36 is sleeved on the first eccentric wheel 31. A cam 39 is sleeved on the outer side of the bearing 36. The cam 39 is pivotally connected to the connecting plate 4 through a second pivot 62. Specifically, a bolt hole is provided on the cam 39, and the second pivot 62 is a bolt shaft. During assembly, the bolt shaft is inserted through the bolt hole and connected to the second connecting hole 44 on the connecting plate 4. When the first eccentric wheel 31 rotates, the connecting plate 4 can be driven to swing left and right through the cam 39.

[0055] In this embodiment, by arranging the motor 2 and the connecting plate 4 side by side, the installation thickness of the entire massage mechanism is reduced. By setting the first eccentric wheel 31 and the cam 39 to control the swing of the connecting plate 4, the knocking massage effect is achieved through the connecting plate 4. By setting an adjustable knocking massage head 5 to perform massage, and the knocking massage head 5 can be retracted, so that the height of the knocking massage head 5 can be reduced when not in use, without affecting the comfort of the user. Through this solution, the height of the massage mechanism can be relatively thin, which can not only meet traditional massage chairs, massage cushions, etc., but also be used on sofas and car seats; moreover, the height and strength of the knocking massage head 5 can be adjusted to meet the needs of different experiencers. In addition, this device has the advantages of low cost, simple structure, high portability, and a wide range of use and applicable scenarios.

[0056] Embodiment 2

[0057] Combined with Figures 6 to 13 As shown, the difference between this embodiment and Embodiment 1 is that the eccentric mechanism 3 includes an eccentric wheel, an eccentric shaft, and a bearing seat 35 sleeved on the eccentric shaft. The bearing seat 35 has a support handle 351, and the connecting plate 4 has a card slot that cooperates with the support handle 351. By setting the eccentric shaft to control the rotation of the eccentric wheel, the knocking effect achieved in this way is better than that achieved by using only the eccentric wheel. Further, two sets of the eccentric mechanism 3 are provided and are respectively connected to the left and right sides of the connecting plate 4 in a power transmission manner, thereby improving the stability of the left and right swing of the connecting plate 4 and enhancing the massage effect.

[0058] As Figure 8 and Figure 11 shown, a first eccentric mechanism 3 and a second eccentric mechanism 3 that are parallel to each other are rotatably provided on the base 1, and the eccentric directions of the first eccentric mechanism 3 and the second eccentric mechanism 3 are opposite, so that when the first eccentric mechanism 3 drives one side of the connecting plate 4 to swing downward, the second eccentric mechanism 3 drives the other side of the connecting plate 4 to swing upward; conversely, when the second eccentric mechanism 3 drives one side of the connecting plate 4 to swing downward, the first eccentric mechanism 3 drives the other side of the connecting plate 4 to swing upward, thereby causing the connecting plate 4 to swing left and right, thus enhancing the overall structural stability and durability of the massage mechanism. By providing parallel eccentric shafts on the base 1 and connecting them to the connecting plate 4 through the bearing seat 35, the transmission process is made more stable, reducing vibration and noise.

[0059] Specifically, the first eccentric mechanism 3 includes a first eccentric wheel 31 and a first eccentric shaft 33 that is drivingly connected to the first eccentric wheel 31. Two bearings 36 are connected to the first eccentric shaft 33, and a bearing seat 35 is sleeved on each bearing 36. A support handle 351 is provided on the bearing seat 35, and the support handle 351 is connected to the connecting plate 4 through a rubber pad 38. The second eccentric mechanism 3 includes a second eccentric wheel 32 and a second eccentric shaft 34 that is drivingly connected to the second eccentric wheel 32. Two bearings 36 are also connected to the second eccentric shaft 34, and a bearing seat 35 is sleeved on each bearing 36. A support handle 351 is provided on the bearing seat 35, and the support handle 351 is connected to the connecting plate 4 through a rubber pad 38. Here, the four support handles 351 are all connected to the same connecting plate 4 through rubber pads 38. The rubber pads 38 are sleeved on the support handles 351. By driving the swing of the connecting plate 4 through the four support handles 351, the swing of the connecting plate 4 can be made more stable; moreover, the use of the rubber pads 38 increases the buffering effect of the connection part, further improving the stability and durability of the structure.

[0060] The first eccentric wheel 31 is power-connected to the output shaft of the motor 2, and the second eccentric wheel 32 is drivingly connected to the first eccentric wheel 31 through a belt. By using the combination of the eccentric shaft and the transmission belt 37, the efficient transmission of power is achieved, and at the same time, the problem of the increase in the thickness of the movement caused by placing the massage arm above or on both sides of the motor 2 in the traditional design is avoided. When the percussion massage head 5 retracts, the connecting plate 4 can naturally fit the base 1, greatly reducing the overall thickness of the massage movement and making it more suitable for scenarios with limited space such as car seats and sofas.

[0061] In this embodiment, a first connection hole 43 is horizontally provided at the middle position of the connecting plate 4. The connecting plate 4 is locked to the base 1 through a first pivot 61 and can swing around the first pivot 61. The positions of the two percussion massage heads 5 relative to the first pivot 61 can be symmetrically arranged. Of course, a gland can also be provided above the connecting plate 4 to limit the position of the rubber pad 38.

[0062] Embodiment 3

[0063] Combined with Figure 14 As shown, the difference between this embodiment and any of the above embodiments is that the motor 2 is provided with two output shafts, and a massage assembly is connected to each output shaft. Two of the percussion massage heads 5 are provided on each massage assembly. This solution can drive the work of two connecting plates 4 and four massage percussion massage heads 5 simultaneously through a motor 2 with a double output shaft, facilitating the realization of more massage positions with fewer structures and improving the massage effect. Here, the structures of the two massage assemblies are similar and can be controlled by a single motor 2, which helps to reduce the production cost.

[0064] Of course, in some embodiments, two massage components may also be connected side by side on the output shaft, so as to increase more massage positions and improve the massage effect.

[0065] Embodiment 4

[0066] The fourth embodiment of the present utility model provides a massage device, which is installed with the above-mentioned thin massage movement. Since the thin massage movement of the present utility model has the characteristics of small thickness and compact structure, it can be more flexibly embedded into various furniture and equipment. The massage device can be a massage chair, a massage cushion, etc., or a sofa, a car seat, etc. Through the structural design of the massage movement, the height and thickness of the entire movement are reduced, achieving true ultra-thinness, effectively utilizing the height space, and enriching the application scenarios of the massage movement.

[0067] Furthermore, the present utility model provides a chair-type massage machine, including a chair and a massage movement, and the massage movement is disposed at the backrest of the chair. Among them, the massage movement is the thin massage movement of any one of the foregoing. With the above design, the thinness of the chair-type massage machine can be improved, and when the massage movement is not working, the user will not feel an obvious foreign body sensation when leaning on the chair backrest, thereby improving the use experience. Since when the user lies back, the contact area between the scapula or the thoracic rib and the chair backrest is the largest, and it is also easier to feel the foreign body sensation; in this embodiment, the massage movement is configured to be installed at a position corresponding to the scapula or the thoracic rib on the chair backrest, so as to reduce the foreign body sensation when the user leans and improve the use comfort.

[0068] Furthermore, the massage movement is configured to be able to travel along the backrest of the chair, so that the entire back of the user can be tapped and massaged, improving the use comfort.

[0069] Embodiment 5

[0070] The fifth embodiment of the present utility model provides an automobile seat, which includes a seat and a massage movement, and the massage movement is the thin massage movement of any one of the foregoing. By adopting the above massage movement, the thickness of the automobile seat can be reduced, and when not massaging, the percussion massage head 5 will also retract to make the massage movement thinner, so as not to cause an obvious foreign body sensation to the user, improving the sitting comfort, and the reduction of the thickness of the automobile seat can also reduce the space occupied by the automobile, effectively utilizing the space.

[0071] Preferably, the present utility model further provides a means of transportation, including the above-mentioned automobile seat, enriching the application scenarios of the product. The means of transportation can be an automobile, a ship, etc.
