Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically to a support unit and seat with a massage function. Background Technology

[0002] Existing office chairs, gaming chairs, and study chairs are typically equipped with headrests and lumbar support units to provide support for corresponding parts of the user's body, relieving fatigue and improving chair comfort. To further enhance comfort, some chairs incorporate massage mechanisms within their headrests and lumbar support. While the headrests and lumbar support provide support for the user's head and lower back, the massage mechanisms provide massage. Taking existing headrests as an example, the headrest contains a massage mechanism and a drive unit that moves the massage mechanism back and forth. The drive unit generally includes a motor and a lead screw transmission mechanism driven by the motor. The motor and lead screw transmission mechanism occupy a significant amount of space in the back-and-forth direction, resulting in a large internal space for the headrest. This limits the range of motion of the massage mechanism in the back-and-forth direction, leading to poor massage effect. Furthermore, the large size of the headrest in the back-and-forth direction is not conducive to its placement on the chair. Utility Model Content

[0026] like Figure 1 , 2As shown in Figure 3, this utility model discloses a support unit with a massage function, particularly a headrest with a massage function. It is installed on the top of a seat back support and specifically includes an outer frame 10, a support 20, a movable seat 30, a massage mechanism 40, an airbag 50, and an inflation / deflation mechanism. A flexible shielding part is provided on the front side of the outer frame 10. The flexible shielding part can be made of woven fabric, molded cotton, or other flexible components, covering the front side of the outer frame 10 so that the outer frame 10 and the flexible shielding part form a receiving space. The support 20, the movable seat 30, and the massage mechanism 40 are all located within this receiving space. In the space; the bracket 20 is fixedly connected to the back plate 11 of the outer frame 10. The fixation between the bracket 20 and the back plate 11 can be achieved by bolts or clips to facilitate the assembly of the entire headrest. The movable seat 30 is mounted on the bracket 20 so that the movable seat 30 can move relative to the bracket 20 in the front-back direction. The massage mechanism 40 is mounted on the movable seat 30 so that the massage head 41 on the massage mechanism 40 faces the flexible shield. The massage head 41 provides support to the flexible shield on the rear side of the flexible shield, thereby providing massage to the head and neck of the human body that is against the front side of the flexible shield. The airbag 50 is positioned between the support 20 and the movable seat 30. The front side of the airbag 50 is connected to the movable seat 30, and the rear side is connected to the support 20. The inflation / deflation mechanism specifically includes an air pump 60 connected to the airbag 50 and an exhaust valve connected to the airbag 50. The air pump 60 is used to inflate the airbag 50, and the exhaust valve is used to discharge the gas inside the airbag 50 when it is opened. The air pump 60 is connected to the airbag 50 through an air guide tube 61, and the exhaust valve can be a solenoid valve installed on the air guide tube 61. In use, the exhaust valve is closed, and the air pump 60 is used to inflate the airbag 50, causing the airbag 50 to expand. When the exhaust valve is opened, the gas inside the airbag 50 is discharged through the air guide tube 61 and the exhaust valve, causing the airbag 50 to contract. In this way, the airbag 50 can drive the movable seat 30 to move back and forth relative to the support 20. Of course, the inflation / deflation mechanism can also be any other mechanism that can inflate the airbag 50 and expel the gas inside the airbag 50, as long as it can inflate and deflate the airbag 50.

[0027] It should be noted that the above description of the present invention is based on the example of the headrest of the seat. The support unit of the present invention can also be a lumbar pillow installed on the seat to support the user's waist or a backrest to support the user's back.

[0028] In this invention, the extension and contraction of the airbag 50 drives the movable seat 30 to move back and forth, which in turn drives the massage mechanism 40 to move back and forth, giving the massage mechanism 40 a large range of motion in the front-back direction to meet the requirements of massaging the user's body parts. The airbag 50 occupies little space in the front-back direction, especially when the airbag 50 is contracted, it hardly occupies any space in the front-back direction, thus making the front-back dimensions of the entire support unit relatively small. In addition, when the airbag 50 is deployed, it provides elastic support to the movable seat 30, giving the massage mechanism 40 a small range of front-back movement when massaging the user's body parts, avoiding the massage mechanism 40 from applying rigid pressure to the user's body parts, and improving comfort.

[0029] In a preferred embodiment, the bracket 20 has a first connecting surface perpendicular to the front-rear direction, and the movable seat 30 has a second connecting surface opposite to the first connecting surface. The front and rear sides of the airbag 50 are respectively connected to the second connecting surface and the first connecting surface by adhesive bonding. Using adhesive bonding to connect the airbag 50 to the bracket 20 and the movable seat 30 further reduces the space occupied by the airbag 50 in the front-rear direction. In other embodiments, buckles or threaded holes may be provided on the front and rear sides of the airbag 50, allowing the airbag 50 to be detachably fixed to the bracket 20 and the movable seat 30 by snap-fit ​​or threaded connection, facilitating replacement of the airbag 50 when it is damaged. The bracket 20 includes an end wall 21 and a side wall 22 extending forward from the periphery of the end wall 21. The side wall 22 and the end wall 21 form a receiving groove, and the front side of the end wall 21 forms the aforementioned first connecting surface. The movable seat 30 is embedded in the receiving groove. The rear end face of the movable seat 30 forms a second connecting surface. The outer peripheral surface of the movable seat 30 abuts against the inner side of the side wall 22 of the support 20, and the outer peripheral surface of the movable seat 30 slides in contact with the side wall 22 of the support 20. In this way, the receiving groove on the support 20 can not only accommodate the movable seat 30, but also guide the back-and-forth movement of the movable seat 30. In addition, a guide groove 221 extending in the back-and-forth direction is provided on the inner surface of the side wall 22, and a guide rib 301 slidably embedded in the guide groove 221 is provided on the outer peripheral surface of the movable seat 30. Through the sliding engagement of the guide rib 301 with the guide groove 221, the back-and-forth movement of the movable seat 30 is further guided, preventing it from swaying during its back-and-forth movement. Of course, the guide groove 221 can also be provided on the outer peripheral surface of the movable seat 30, and the guide rib 301 can be provided on the side wall 22 of the support 20 accordingly.

[0030] A back plate 11 is provided on the rear side of the outer frame 10. The back plate 11, the outer frame 10, and the flexible shielding part form a closed space. The bracket 20 is fixed on the back plate 11. The air pump 60 is located inside the receiving space and is installed on the bracket 20 or the back plate 11 of the outer frame 10. A fixing seat 23 can be provided on the top of the bracket 20, and the housing of the air pump 60 can be fixed on the fixing seat 23, so that the air pump 60 occupies as little space as possible in the front-back direction inside the receiving space and makes full use of the space in the vertical direction inside the receiving space. During assembly, the airbag 50 can be glued and fixed to the bracket 20 and the movable seat 30 respectively. Then, the massage mechanism 40 is installed on the movable seat 30, the air pump 60 is fixed on the bracket 20, and the assembly formed by the bracket 20, the movable seat 30, the massage mechanism 40, the airbag 50, and the air pump 60 is installed on the back plate 11. Finally, the periphery of the flexible shielding part is connected to the edge of the outer frame 10. The airbag 50 includes two symmetrical inflation / deflation areas 51. The air pump 60 has two air guide tubes 61 connected to the two inflation / deflation areas 51 respectively. By inflating the two inflation / deflation areas 51 of the airbag 50 through the two air guide tubes 61, the airbag 50 can expand forward relatively evenly on both sides, so that the movable seat 30 can move forward smoothly. Similarly, the two air guide tubes 61 simultaneously discharge the gas from the two inflation / deflation areas 51 outward, so that the movable seat 30 can move backward smoothly.

[0031] A clearance groove 501 is formed between the two inflation / deflation areas 51 of the airbag 50. A first clearance hole 211, directly opposite the clearance groove 501, is provided on the end wall 21 of the support 20. A second clearance hole 311, directly opposite the clearance groove 501, is provided on the movable seat 30. A motor housing 42 protrudes from the rear side of the massage mechanism 40. The motor housing 42 houses the motor that drives the massage head 41. The rearward protrusion of the motor housing 42 allows the massage mechanism 40 to accommodate a more powerful motor, thus improving massage comfort. The motor housing 42 is sequentially embedded from front to back into the second clearance hole 311, the clearance groove 501, and the first clearance hole 211, preventing interference between the massage mechanism 40 and the movable seat 30, the airbag 50, and the support 20, further reducing the front-to-back dimensions of the support unit.

[0032] The movable base 30 is provided with a receiving groove 31 that is recessed from its front end to its rear end. The massage mechanism 40 is installed on the rear end face of the receiving groove 31, so that the massage mechanism 40 is housed in the receiving groove 31. The massage head 41 of the massage mechanism 40 protrudes from the front end face of the movable base 30 and abuts against the rear side of the flexible shield. Placing the massage mechanism 40 in the receiving groove 31 further reduces the front and rear dimensions of the support unit. At the same time, the receiving groove 31 provides protection for the massage mechanism 40, preventing the massage mechanism 40 from being damaged by collision.

[0033] The seat of this utility model includes the aforementioned support unit with massage function. The other structures of the seat are the same as those in the prior art and will not be described in detail here.

[0034] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
