Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 5, in a car seat, a backrest a of the seat has a lumbar region a2 and a back region a1, and a user sits on the seat with the lumbar region a2 and the back region a1 corresponding to the lumbar and back of a human body. The lumbar region a2 and the back region a1 of the backrest a are each provided with a massage device B for massaging the waist and the back of the occupant, respectively.

In this embodiment, the massage device B has the following specific implementation structure:

referring to fig. 1 to 4, the massage device B includes the following main components: the massage device comprises a mounting seat 1, a rotating shaft 2, a driving mechanism 3, a rotating wheel 4, a screw rod 5, a massage head 6, a limiting sheet 7, a friction sheet 8 and a spring 9. The rotating shaft 2 and the rotating wheel 4 are both rotatably arranged on the inner side of the mounting seat 1, the rotating direction of the rotating wheel 4 is perpendicular to the rotating direction of the rotating shaft 2, a threaded hole is formed in the middle of the rotating wheel 4, the screw rod 5 is in threaded connection with the threaded hole along the axial direction of the rotating wheel 4, the upper end of the screw rod 5 penetrates out of the avoiding hole 1a of the mounting seat 1, the massage head 6 is fixedly arranged at the upper end of the screw rod 5, the upper surface of the massage head 6 is provided with a first massage surface 6a in an arc-shaped structure, a protruding portion 6b extending upwards is arranged at the edge position of one end of the first massage surface 6a, the upper surface of the protruding portion 6b is in the arc-shaped structure, the friction plate 8 is fixedly arranged on the lower side of the massage head 6, the spring 9 preferably adopts a tower-shaped spring, the large-diameter end of the tower-shaped spring is fixed on the mounting seat 1, the small-diameter end is in friction butt joint with the lower-side surface of the friction plate 8, and the lower end of the screw rod 5 is fixedly provided with the limiting plate 7. The driving mechanism 3 is fixedly connected with the mounting base 1, in the implementation, the driving mechanism 3 is a speed reducing motor, and when the massage device B works, the speed reducing motor is used for driving the rotating shaft 2 to rotate.

Based on the structural arrangement, the working principle of the massage device B is as follows:

when the massage function is not started, the spring 9 is in a highly compressed state, the friction plate 8 and the mounting seat 1 have a minimum distance, and the massage head 6 is far away from the waist of a driver and a passenger and does not contact the back of a human body, so that the safety of the seat can be ensured not to be influenced by the massage head 6.

When the user needs to use the massage function, actuating mechanism 3 works, gear motor drive pivot 2 rotates, pivot 2 drives again and rotates wheel 4 and rotates, because spring 9 supports between friction disc 8 and mount pad 1, the rotation of rotating wheel 4 this moment can drive screw rod 5 and rise, thereby make massage head 6 rise to driver and crew's back position, treat that massage head 6 rises to back position after, spacing piece 7 and the lower extreme butt of rotating wheel 4, screw rod 5 does not further rise, but along with rotating wheel 4 synchronous rotation, massage head 6 then begins to make rotary motion this moment, thereby realize massaging user's back, operation such as knead, can fully alleviate the tired sense that driver and crew sat for a long time. After the massage is finished, the driving mechanism 3 moves reversely to enable the massage head 6 to leave the waist position of the driver and the passenger.

In order to provide the seat with the massage with all-round back comfort, each massage device B is provided with four massage heads 6, so that the rotating wheels 4 corresponding to the massage heads 6 are also four, the four rotating wheels 4 are distributed in a rectangular shape on the inner side of the mounting seat 1, and the four rotating wheels 4 are symmetrically distributed on two sides of the rotating shaft 2 in the radial direction. In order to ensure the reliability of power transmission, the power is transmitted between the rotating wheel 4 and the rotating shaft 2 in a worm gear or helical tooth meshing manner, and the power is preferably transmitted in a helical tooth meshing manner in the embodiment, specifically: the rotating shaft 2 is sleeved with a helical gear 2a corresponding to the rotating wheel 4, a helical gear part 4a meshed with the helical gear 2a is formed on the circumference of the rotating wheel 4, and the driving mechanism 3 can drive the four massage heads 6 to move simultaneously when working.

The lower end of the spring 9 provided by the embodiment is fixedly connected with the mounting seat 1, and the upper end of the spring is in frictional contact with the friction plate 8; in addition to this, it is also possible to provide the friction plate 8 at the lower end of the spring 9, i.e.: the friction plate 8 is arranged on the mounting seat 1, the lower end of the spring 9 is in friction contact with the friction plate 8, and the upper end of the spring is fixedly connected with the massage head 6.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
