Description

Technical Field

[0001] The invention relates to the technical field of massage equipment, and in particular to a combined massage device. Background Art

[0002] With the rapid development of the automotive industry, cars are widely used in work and life. As people's living standards improve, in addition to the basic functions of cars meeting people's daily needs, people have higher and higher requirements for the comfort of car seats, and the massage function is an indispensable part of comfort, especially on long-distance trips. Maintaining the same posture for a long time can easily lead to physical fatigue and discomfort, which massage seats can effectively relieve.

[0003] At present, some car seats with massage functions have been launched on the market. Most massage seats only provide massage functions for the waist and back, while ignoring other fatigue-prone areas such as shoulders. The massage methods mainly include air bag massage and mechanical massage. Among them, the air bag massage method achieves push and contraction massage by inflating and deflating the air bag, but its massage effect is weak and the strength is soft, which is difficult to be favored by all consumers. Although the mechanical massage method can provide sufficient massage strength, it is difficult to maintain a high degree of integration in the complex mechanical structure of the backrest frame with extremely limited design space, which often leads to a bloated structure of the entire chair. The simple mechanical structure has a single massage method and limited effect in relieving fatigue. Summary of the invention

[0004] In view of this, the present invention provides a combined massage device, which has the technical advantages of simple structure and good comfort.

[0036] The present invention is further described below in conjunction with embodiments and drawings.

[0037] like Figure 1 and Figure 2 As shown, a massage seat is provided with a combined massage device integrated in the shoulder part. The massage device is fixedly assembled in the seat back B through a shell assembly 1. A rotating massage mechanism 2 and a finger pressure massage mechanism 3 are symmetrically provided at both ends of the shell assembly 1. The rotating massage mechanism 2 can apply a massage force to the user's back in a continuous rotating manner. The finger pressure massage mechanism 3 can continuously and intermittently apply a top pressure to the user's back to simulate a finger pressure massage. A driving mechanism 4 is also provided on the shell assembly 1. The driving mechanism 4 can drive the rotating massage mechanism 2 and the finger pressure massage mechanism 3 to work simultaneously.

[0038] like Figure 1 and Figure 3 As shown, a first mounting inner hole 11 is respectively provided at the left and right ends of the housing assembly 1, and the rotary massage mechanism 2 includes a cylindrical rotary massage head 21 rotatably arranged in the first mounting inner hole 11, and the outer end of the rotary massage head 21 has a first massage portion 211 with a curved surface structure, and the curved surface structure is also provided with two protrusions, which can achieve a better massage effect. A spiral groove 212 and an annular groove 213 are provided on the outer wall of the rotary massage head 21, and the annular groove 213 is located at an end away from the first massage portion 211, and one end of the spiral groove 212 is closed, and the other end is connected to the annular groove 213; a first guide pin 23 is inserted on the inner wall of the first mounting inner hole 11, and the part of the first guide pin 23 that exceeds the inner wall is the first guide portion 111, and the spiral groove 211 and the annular groove 213 are slidably matched with the first guide portion 111.

[0039] When the driving component 4 drives the rotating massage head 21 to rotate forward, it can first force the rotating massage head 21 to rise under the guidance of the spiral groove 212 and the first guide part 111. After the rotating massage head 21 rises to the highest position, it is constrained by the annular groove 213 and the first guide part 111 to force the rotating massage head 21 to rotate continuously to achieve rotational massage. When the driving component 4 drives the rotating massage head 21 to rotate reversely, it can force the rotating massage head 21 to retract downward into the first mounting inner hole 11 under the guidance of the spiral groove 212.

[0040] like Figure 3 and Figure 4 As shown, the first guide portion 111 is installed on the inner wall through the elastic element spring sheet 22, and a buffer groove 214 is widened at the connection between the spiral groove 212 and the annular groove 213. The buffer groove 214 includes a buffer plane A connecting the spiral groove 212 and the annular groove 213. The spring sheet 22 can provide an upward force to the first guide portion 111. When the rotating massage head 21 rotates forward, the first guide portion 111 cooperates with the upper surface of the annular groove 213 and slides relative to the annular groove 213. When passing through the buffer groove 214, under the guidance of the buffer plane A, the rotating massage head 21 will not be interfered by the spiral groove 212, and smoothly enters the annular groove 213 and continues to rotate for massage. When the rotary massage head 21 rotates in the opposite direction, the first guide portion 111 transitions from the annular groove 213 to the spiral groove 212. When located in the buffer groove 214, the seat cover provides a downward force for the rotary massage head 21. At the same time, the spring sheet 22 can provide an upward force for the first guide portion 111. The double protection ensures that the first guide portion 111 smoothly enters the spiral groove 213 and is retracted.

[0041] like Figure 1 and Figure 5 As shown, a second mounting inner hole 12 is respectively provided at the left and right ends of the housing assembly 1, and the acupressure massage mechanism 3 includes a cylindrical acupressure massage head 31 rotatably disposed in the second mounting inner hole 12, a sinusoidal groove 311 is provided on the outer wall of the acupressure massage head 31, a second guide pin 32 is inserted into the second mounting inner hole 12, and the portion of the second guide pin 32 that exceeds the second mounting inner hole 12 is the second guide portion 121, and the sinusoidal groove 311 is slidably matched with the second guide portion 121; while the driving mechanism 4 drives the acupressure massage head 31 to rotate, under the guidance and constraint of the second guide portion 121 and the sinusoidal groove 311, the acupressure massage head 31 can be reciprocatedly ejected and retracted relative to the second mounting inner hole 12. In this embodiment, the sinusoidal groove 311 includes two sinusoidal periods, such as Figure 6 As shown, two second guide pins 32 are symmetrically inserted into the second mounting inner hole 12, so that the acupressure massage head 31 is evenly stressed and moves smoothly.

[0042] like Figure 7As shown, the driving component 4 includes a motor 43 arranged in the middle of the shell assembly 1, a first gear 41 connected to the bottom of the rotary massage head 21, and a second gear 42 connected to the bottom of the acupressure massage head 31. The first gear 41 and the second gear 42 located at the same end of the shell assembly 1 are connected in transmission, and the first gear 41 is located on the outside of the second gear 42. The motor 43 is arranged parallel to the first gear 41 and the second gear 42. The output shaft is connected to the worm 44, and the radial sides of the worm 44 are connected to the turbines 45. The two turbines 45 are respectively meshed with the second gear 42 to realize transmission.

[0043] like Figure 8 As shown, the first gear 41 and the second gear 42 have a rotating shaft 412 extending axially upward, the rotating massage head 21 and the acupressure massage head 31 have a central inner hole sleeved on the rotating shaft 412, the side wall of the rotating shaft 412 is provided with an axial limiting groove 412a, and the side wall of the central inner hole is provided with a protruding structure adapted to the limiting groove 412a, and the protruding structure cooperates with the limiting groove 412a, so that the rotating massage head 21 and the acupressure massage head 31 can slide up and down while respectively following the rotation of the first gear 41 and the second gear 42.

[0044] like Fig. 9 As shown, the gear set and the motor 43 are arranged in a planar manner as a whole. When the motor 43 drives the rotating massage head 21 to reverse and retract, the rotating massage head 21 stops at the lowest point. At this time, the acupressure massage head 31 is also at the lowest position. Combined with the foaming, the surface of the shoulder strap can be made smooth to avoid the discomfort of the car seat.

[0045] In this embodiment, the forward rotation and reverse rotation of the rotating massage head 21 are a set of relative concepts. When the forward rotation means clockwise rotation, the reverse rotation means counterclockwise rotation. When the forward rotation means counterclockwise rotation, the reverse rotation means clockwise rotation. Therefore, whether the forward rotation (ascending process) of the rotating massage head 21 is clockwise or counterclockwise, it should fall within the protection scope of this application.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
