[0024] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] An embodiment of the first aspect of the present invention is to provide a seat, such asFigures 1 to 3 As shown in the figure, it includes a seat body 1, a first driver 2, a second driver 3, a placement component 4, and a plurality of rotating shafts 5; The first driver 2 and each rotating shaft 5 are installed inside the seat body 1. The rotating shafts 5 are arranged side by side and are all rotatably connected to the seat body 1. One end of each rotating shaft 5 is sequentially engaged through a gear 6. The first driver 2 is connected to any one of the rotating shafts 5 to drive the rotating shaft 5 to rotate. Massage bumps 7 are provided on each rotating shaft 5; The placement component 4 is slidably matched with the seat body 1. The placement component 4 is used to support the human legs. The second driver 3 is arranged inside the seat body 1 and is connected to the placement component 4 to drive the placement component 4 to move closer to or away from the seat body 1.

[0026] When the seat provided by the embodiment of the first aspect of the present invention is in use, as Figure 2 shown, the first driver 2 can be turned on, and the rotating shaft 5 connected to the first driver 2 rotates. Since the rotating shafts 5 are arranged side by side and one end of each rotating shaft 5 is sequentially engaged through a gear 6, the remaining rotating shafts 5 will also rotate accordingly. The massage bumps 7 on each rotating shaft 5 can massage the human body. At the same time, as Figure 3 shown, the second driver 3 can drive the placement component 4 to move away from the seat body 1 to support the human legs, making the user more comfortable.

[0027] In the above embodiment, since each rotating shaft 5 is sequentially engaged through a gear 6, the rotation directions of two adjacent rotating shafts 5 relative to the seat body 1 are opposite.

[0028] Specifically, the rotating shafts 5 are equidistantly distributed inside the seat body 1.

[0029] In an alternative embodiment, as Figure 2 shown, there is a symmetry plane 8 between any two adjacent rotating shafts 5. The rotating shafts adjacent to both sides of the symmetry plane 8 are symmetrically arranged with respect to the symmetry plane 8; when the first driver 2 drives the rotating shaft 5 connected to it to rotate, the protruding directions of the massage bumps 7 on two adjacent rotating shafts 5 form equal angles with the symmetry plane 8 corresponding to the two rotating shafts 5.

[0030] For example, when the first driver 2 acts, among two adjacent rotating shafts 5, when the protruding part of the massage bump 7 on one rotating shaft 5 gradually approaches the symmetry plane 8 and rotates, the protruding part of the massage bump 7 on the other rotating shaft 5 also gradually approaches the symmetry plane 8 and rotates. Since the protruding directions of the massage bumps 7 on two adjacent rotating shafts 5 form equal angles with the symmetry plane 8 corresponding to the two rotating shafts 5, the forces exerted by the above two rotating shafts 5 on the human body are the same, and they can jointly massage the human body.

[0031] The above-mentioned first driver 2 can be, but is not limited to, a rotating motor.

[0032] In an alternative embodiment, the massage bumps 7 on any two adjacent rotating shafts 5 are projected towards the symmetry plane 8 between the two rotating shafts 5 along the arrangement direction of each rotating shaft 5, and the projections of the massage bumps 7 on one rotating shaft 5 are staggered from the projections of the massage bumps 7 on the other rotating shaft 5.

[0033] The above embodiment makes the distribution of the massage bumps 7 on two adjacent rotating shafts 5 more dispersed, enabling massage of different parts of the human body and avoiding over-concentration of massage points.

[0034] The number of rotating shafts 5 can be even or odd. When the number of rotating shafts 5 is even, the first driver 2 can be connected to any one of the two middle rotating shafts 5; when the number of rotating shafts 5 is odd, the first driver 2 can be connected to the middle rotating shaft 5.

[0035] In an alternative embodiment, it is set that each rotating shaft 5 includes a first rotating shaft 51 connected to the first driver 2, and a plurality of second rotating shafts 52 located on one side of the first rotating shaft 51 and a plurality of third rotating shafts located on the other side of the first rotating shaft 51 along the arrangement direction of each rotating shaft 5.

[0036] Among them, the seat body 1 includes a backrest 12, a first connecting seat 13 and a second connecting seat. The first connecting seat 13 and the second connecting seat are both slidably engaged with the backrest 12 along the arrangement direction of each rotating shaft 5. At least two second rotating shafts 52 at the ends are rotatably engaged with the first connecting seat 13, and at least two third rotating shafts at the ends are rotatably engaged with the second connecting seat.

[0037] The structures of the first connecting seat 13 and the second connecting seat are the same. Taking the first connecting seat 13 as an example for specific description. As Figure 4 shown, the first connecting seat 13 is U-shaped; both ends of the second rotating shaft 52 are rotatably connected to the first connecting seat 13 through bearings; both ends of the first connecting seat 13 in the extending direction of the second rotating shaft 52 are recessed with sliding grooves 131, and the sliding grooves 131 are slidably engaged with the fixing blocks in the backrest 12; one end of the first connecting seat 13 in the extending direction of the second rotating shaft 52 is provided with a rack 132. Two motors are installed in the backrest 12, and the power output ends of the two motors are both provided with driving gears, and the two driving gears are respectively engaged with the racks on the first connecting seat 13 and the second connecting seat.

[0038] When the motor operates, since the driving gear is engaged with the rack 132, it can drive the first connecting seat 13 to slide along the arrangement direction of each rotating shaft 5, as Figure 5As shown, each second rotating shaft 52 on the first connecting seat 13 is far from the first rotating shaft 51. At this time, when the first driver 2 operates, the power of the first rotating shaft 51 will not be transmitted to each second rotating shaft 52. When the motor drives each second rotating shaft 52 on the first connecting seat 13 to move closer to the first rotating shaft 51, the transmission connection between the first rotating shaft 51 and the second rotating shaft 52 can also be achieved.

[0039] The above-mentioned embodiment can adjust the number of rotating shafts 5 participating in the massage, facilitating the user to adjust the massage area.

[0040] In an alternative embodiment, each second rotating shaft 52 on the first connecting seat 13 can be arranged opposite to the user's left arm, each third rotating shaft on the second connecting seat can be arranged opposite to the user's right arm, and the remaining rotating shafts 5 can be arranged opposite to the user's back.
