DETAILED DESCRIPTION

[0037] The following combination Figure 1-Figure 7 The present invention will be described in detail.

[0038] A vehicle massage device includes a massage body and a backrest 130. The massage body is arranged on the backrest 130. The massage body includes an upper cover 10 and a lower cover 20 connected to each other. A drive assembly is provided in the space enclosed by the upper cover 10 and the lower cover 20. The drive assembly includes a transmission member 301 and a drive device 302 for driving the transmission member 301 to rotate. The transmission member 301 is provided with a slide groove 3011 arranged along its axial direction; and further includes:

[0039] The connecting shaft 40 has one end connected to the massage head 50, and the backrest 130 is provided with a space for the massage head 50 to move. The other end is connected to the slide groove 3011, and the other end of the connecting shaft 40 is configured to be movable along the axial direction of the slide groove 3011 and circumferentially limited and connected to the slide groove 3011, and,

[0040] The airbag 60 is sleeved on the outer side of the connecting shaft 40 . One end of the airbag 60 abuts against the massage body, and the other end of the airbag 60 acts on the connecting shaft 40 .

[0041] During use, the massage head 50 rotates via the drive assembly 302, and its elevation is controlled by the inflation and deflation of the airbag 60. Thus, while retaining the high comfort of the airbag 60 vehicle massage device and readily meeting the collision safety requirements of automobile seats, the massage head 50 acts on the user's back, improving the relatively poor rigidity of the airbag 60 vehicle massage device. Furthermore, by varying the output mode of the drive assembly, the rotation mode of the massage head 50 can be changed, thereby achieving different massage actions and enhancing the user experience. This car seat has a high degree of overall modularity, requiring minimal modifications to existing vehicle seats, making it easier to promote and implement.

[0042] like Figures 1 to 3 As shown, the driving device 302 is a driving motor with dual output ends. The output end of the motor is integrally formed or installed with a worm. The transmission member 301 is provided with a worm gear adapted to the worm, so that the rotation of the two massage heads 50 can be achieved through a single driving motor, which is low-cost and has a more compact overall structure. At the same time, the two massage heads 50 are respectively equipped with air bags 60. The two air bags 60 can be inflated and deflated at the same time, or they can be inflated and deflated separately, so that the two massage heads 50 are ejected at different times, bringing a better massage experience. In other embodiments, such as Figure 4 As shown, the number of massage heads 50 may also be four to provide a larger massage area and more massage modes.

[0043] In this embodiment, Figure 3As shown, the massage seat also includes a cushioning support 70 secured to the backrest 130. The massage body is secured to the backrest 130 via the cushioning support 70, further ensuring that it meets the collision safety requirements of automobile seats. The cushioning support 70 is composed of a plurality of transverse and longitudinal steel wires. When the massage body is subjected to external pressure or impact, the massage body compresses the cushioning support 70, causing the cushioning support 70 to deform, further ensuring that it meets the collision safety requirements of automobile seats. Furthermore, the cushioning support 70 includes at least two transverse steel wires 701 spaced laterally apart. The massage body is connected to each of the transverse steel wires 701. When the direction of the pressure applied to the massage body by the user changes, the transverse steel wires 701 deform accordingly, causing the angle of the massage body toward the user to change. The cushioning support 70 also includes at least two longitudinal steel wires 702 spaced longitudinally apart. The middle portion of the longitudinal steel wires 702 connects to the left and right sides of the massage body, and the ends of the longitudinal steel wires 702 are secured to the backrest 130. The steel wires are flexible, reducing noise generated by the massage body during operation. The cushioning support 70 is locked to the massage body by a fixing member, and can also be connected by other means such as welding. An electric control device for opening and closing the massage body is also included, and the electric control device is installed on the cushioning support to improve the integration of the vehicle seat.

[0044] In this embodiment, the outer side elevation of the connecting shaft 40 constitutes the first abutting surface 801, and the inner side elevation of the sliding groove 3011 constitutes the second abutting surface 802. The horizontal cross-sections of the first abutting surface 801 and the second abutting surface 802 are non-circular, so that the first abutting surface 801 and the second abutting surface 802 form a circumferential limit fit. Specifically, as Figure 3 As shown, first flat surfaces are provided on opposite sides of the outer elevation of the connecting shaft 40, and second flat surfaces are provided on opposite sides of the inner elevation of the chute 3011. The first flat surfaces constitute the first abutting surface 801, and the second flat surfaces constitute the second abutting surface 802. During use, the connecting shaft 40 can be extended to any length by inflating the airbag 60, thereby forming a circumferential limit fit between the first abutting surface 801 and the second abutting surface 802, facilitating user operation.

[0045] In this embodiment, Figure 2 As shown, a first stopper 401 is provided at the end of the connecting shaft 40 proximal to the massage head 50, and a second stopper 402 is provided at the end of the connecting shaft 40 distal to the massage head 50. The minimum radial dimensions of the first and second stopper 401, 402 are greater than the maximum radial dimension of the chute 3011. The second stopper 402 is used to prevent the connecting shaft 40 from excessively extending and thereby disengaging from the chute 3011, while the first stopper 401 is used to prevent the connecting shaft 40 from excessively retracting and thereby over-extruding the airbag 60. The first stopper 401 is integrally formed on the shoulder of the connecting shaft 40, and the second stopper 402 is a stopper plate connected to the connecting shaft 40.

[0046] In this embodiment, Figure 2 As shown, the transmission member 301 is provided with a receiving groove 3012, which is connected to the slide groove 3011. The second limiting portion 402 is located in the receiving groove 3012, reducing or avoiding the protrusion of the transmission member 301 at one end of the connecting shaft 40 away from the massage head 50, reducing the overall size, and reducing the installation space requirement of the device.

[0047] In this embodiment, Figure 2 As shown, the portion of the connecting shaft 40 located in the receiving groove 3012 is sleeved with a spring 90, one end of the spring 90 abuts the second limiting portion 402, and the other end of the spring 90 abuts the transmission member 301. When the airbag 60 is deflated, the elastic force generated by the spring 90 can accelerate the return speed of the massage head 50.

[0048] In this embodiment, Figure 3 As shown, the massager 60 further includes a bearing 100, which overlaps the first stop 401. A bearing seat 110 is positioned over the bearing 100, and the other end of the airbag 60 abuts against the bearing seat 110. Locking tabs are provided at each end of the airbag 60, connected to the massager body and the bearing seat 110, respectively. When the connecting shaft 40 rotates, the inner ring of the bearing 100 rotates while the outer ring of the bearing 100 remains stationary, keeping the bearing seat 110 stationary as well. This prevents the airbag 60 from rotating with the connecting shaft 40 and prevents air path entanglement.

[0049] In this embodiment, Figure 3 As shown, a transition piece 120 is further provided between the driving device 302 and the transmission member 301. The transition piece 120 is transmission-connected to the driving device 302 and the transmission member 301. Transition pieces 120 of different specifications can be configured according to usage requirements to achieve a transmission ratio among the driving device 302, the transition piece 120 and the transmission member 301.

[0050] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
