Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a combined massage device and a car seat. Background Technology

[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. Massage function is an indispensable part of comfort, especially during long-distance travel. Maintaining the same posture for a long time can easily lead to physical fatigue and discomfort, which massage seats can effectively relieve.

[0003] Currently, some car seats with massage functions have been launched on the market. Most massage seats only provide massage for the lower back, neglecting other easily fatigued areas such as the shoulders. The massage methods mainly fall into two categories: airbag massage and mechanical massage. Among them, airbag massage uses the inflation and deflation of airbags to achieve a pushing and contracting massage, but its massage effect is relatively weak and the intensity is too soft, making it difficult to appeal to all consumers. While mechanical massage can provide sufficient massage intensity, the complex mechanical structure within the extremely limited design space of the backrest frame makes it difficult to maintain a high degree of integration, often resulting in a bulky overall chair structure. Furthermore, the simple mechanical structure offers a limited massage method, thus having a limited effect on relieving fatigue. Summary of the Invention

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

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A combination massage device, comprising:

[0007] Housing assembly, which is used for secure mounting within the seat back;

[0008] Two sets of rotating massage mechanisms are located at the left and right ends of the housing assembly. The rotating massage mechanisms can apply massage force to the user's back in a continuous rotating manner.

[0009] Two sets of acupressure massage mechanisms are arranged at the left and right ends of the housing assembly. The acupressure massage mechanisms can continuously and intermittently apply top pressure to the user's back to simulate acupressure massage.

[0010] And a drive mechanism, which is used to drive the rotary massage mechanism and the acupressure massage mechanism to work.

[0011] The above structure is simple, the mechanical massage method provides sufficient massage force, and the combination of the rotary massage mechanism and the acupressure massage mechanism results in a good massage effect.

[0012] Preferably, the housing assembly has a first mounting inner hole at each of its left and right ends. The rotary massage mechanism includes a rotary massage head rotatably disposed within the first mounting inner hole. The outer end of the rotary massage head has a first massage portion. The drive mechanism can drive the rotary massage head to rotate within the first mounting inner hole. This structure provides rotary massage.

[0013] Preferably, the outer wall of the rotating massage head is provided with a spiral groove and an annular groove, the annular groove being located at the end away from the first massage part, and one end of the spiral groove communicating with the annular groove; the inner wall of the first mounting inner hole is provided with an inwardly protruding first guide part, and the spiral groove and annular groove are slidably engaged with the first guide part. When the driving mechanism drives the rotating massage head to rotate in the forward direction, the rotating massage head rises and rotates continuously; when rotating in the reverse direction, the rotating massage head retracts downward. With the above structure, the rotating massage mechanism extends out when working and retracts into the first mounting inner hole when not working. Combined with foaming, this ensures a smooth shoulder support surface and avoids any discomfort.

[0014] Preferably, the housing assembly has a second mounting inner hole at each of its left and right ends. The acupressure massage mechanism includes an acupressure massage head rotatably disposed within the second mounting inner hole. The outer wall of the acupressure massage head has a sinusoidal groove, and the inner wall of the second mounting inner hole has an inwardly protruding second guide portion. The sinusoidal groove and the second guide portion are slidably engaged. The drive mechanism is used to drive the acupressure massage head to rotate. Using the above structure, acupressure massage is provided.

[0015] Preferably, two inwardly protruding second guide portions are symmetrically provided on the inner wall of the second mounting inner hole. This structure ensures that the pressure on the acupressure massage head is evenly distributed and moves smoothly.

[0016] Preferably, the bottom of the rotary massage head is connected to a first gear for driving the rotary massage head to rotate, and the bottom of the acupressure massage head is connected to a second gear for driving the acupressure massage head to rotate. The first and second gears located at the same end of the housing assembly are connected in a transmission manner. The drive mechanism includes a motor arranged in the middle of the housing assembly, and the output shaft of the motor is poweredly connected to two second gears at both ends of the housing assembly. Using the above structure, both the rotary massage mechanism and the acupressure massage mechanism are driven simultaneously, resulting in a simple and compact structure.

[0017] Preferably, the first and second gears at both ends of the housing assembly are integrally planar with the motor in the middle of the housing assembly, with the first gear located outside the second gear. This structure results in a compact design, avoiding the bulky overall structure caused by integrating the massage mechanism into the seat.

[0018] Preferably, the first guide portion is mounted on the inner wall of the first mounting hole via an elastic element that allows it to float up and down. This structure allows the first guide portion to slide more smoothly within the spiral groove and annular groove, ensuring that the first guide portion smoothly enters the spiral groove when the rotating massage head retracts.

[0019] Preferably, a buffer groove is widened at the connection between the spiral groove and the annular groove. With the above structure, the first guide portion can smoothly transition between the spiral groove and the annular groove under the guidance of the buffer groove.

[0020] This utility model also provides a car seat, the purpose of which is to provide shoulder massage, taking into account both good functionality and beautiful design.

[0021] To achieve the above objectives, the technical solution of this utility model is as follows:

[0022] A car seat includes a backrest, on which a combined massage device is fixedly mounted at the shoulder position. This structure integrates a shoulder massage device within the limited space of the backrest frame, ensuring both effective massage and aesthetic design.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The combined massage device provided by this utility model provides massage through a rotating massage mechanism and an acupressure massage mechanism. It is a mechanical massage method with good comfort and sufficient intensity.

[0025] 2. When not in use, the rotating massage head and the acupressure massage head are retracted into the mounting holes, which, together with the foam, makes the surface of the shoulder rest flat and avoids any discomfort in the seat.

[0026] 3. The massage device is driven by a motor, and the motor is set vertically to the massage head, avoiding a bulky overall chair structure. The massage mechanism has a simple structure and can be integrated into the shoulder area of ​​the seat back in a more compact way. Attached Figure Description

[0035] Figure 9 This is a top view of the present invention. Detailed Implementation

[0036] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, a massage chair with a combined massage device integrated in the shoulder area is provided. The massage device is fixedly mounted in the seat back B through a housing assembly 1. The housing assembly 1 is symmetrically provided with a rotary massage mechanism 2 and acupressure massage mechanism 3 at both ends. The rotary massage mechanism 2 can apply massage force to the user's back in a continuous rotation manner, and the acupressure massage mechanism 3 can apply top pressure to the user's back intermittently to simulate acupressure massage. The housing assembly 1 is also provided with a drive mechanism 4, which can drive the rotary massage mechanism 2 and the acupressure massage mechanism 3 to work simultaneously.

[0038] like Figure 1 and Figure 3 As shown, the housing assembly 1 has a first mounting inner hole 11 at each of its left and right ends. The rotary massage mechanism 2 includes a cylindrical rotary massage head 21 rotatably disposed within the first mounting inner hole 11. The outer end of the rotary massage head 21 has a first massage portion 211 with a curved surface structure. This curved surface structure also has two protrusions to achieve a better massage effect. The outer wall of the rotary massage head 21 has a spiral groove 212 and an annular groove 213. The annular groove 213 is located at the end away from the first massage portion 211. One end of the spiral groove 212 is closed, and the other end communicates with the annular groove 213. A first guide pin 23 is inserted into the inner wall of the first mounting inner hole 11. The part of the first guide pin 23 that extends beyond the inner wall is the first guide portion 111. The spiral groove 212 and the annular groove 213 slide in cooperation with the first guide portion 111.

[0039] When the drive mechanism 4 drives the rotating massage head 21 to rotate in the forward direction, it can first be forced 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 then forced to rotate continuously under the constraint of the annular groove 213 and the first guide part 111 to achieve rotational massage. When the drive mechanism 4 drives the rotating massage head 21 to rotate in the reverse direction, it can be forced to retract the rotating massage head 21 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 mounted on the inner wall via an elastic element spring sheet 22. 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 in the forward direction, the first guide portion 111 engages 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 is not interfered with by the spiral groove 212 and smoothly enters the annular groove 213 and continues to rotate for massage. When the rotating massage head 21 rotates in the opposite direction, the first guide part 111 transitions from the annular groove 213 to the spiral groove 212. When it is located in the buffer groove 214, the seat cover provides a downward force to the rotating massage head 21, while the spring plate 22 can provide an upward force to the first guide part 111. This dual protection ensures that the first guide part 111 smoothly enters the spiral groove 213 and retracts.

[0041] like Figure 1 and Figure 5 As shown, the housing assembly 1 has a second mounting inner hole 12 at each of its left and right ends. The acupressure massage mechanism 3 includes a cylindrical acupressure massage head 31 rotatably disposed within 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. The portion of the second guide pin 32 extending beyond the second mounting inner hole 12 is a second guide portion 121. The sinusoidal groove 311 and the second guide portion 121 are in sliding engagement. 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 reciprocate outward and retract relative to the second mounting inner hole 12. In this embodiment, the sinusoidal groove 311 includes two sinusoidal cycles, 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 subjected to uniform force and moves smoothly.

[0042] like Figure 7As shown, the drive mechanism 4 includes a motor 43 arranged in the middle of the housing assembly 1, a first gear 41 connected to the bottom of the rotating 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 housing assembly 1 are connected in a transmission manner. The first gear 41 is located outside 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 gear 44. The worm gear 44 is connected to the turbine gears 45 on both radial sides. The two turbine gears 45 mesh with the second gear 42 respectively to realize transmission.

[0043] like Figure 8 As shown, the first gear 41 and the second gear 42 have a rotating shaft 412 extending upward along the axial direction. 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 a limiting groove 412a along the axial direction. The side wall of the central inner hole is provided with a protrusion structure that adapts to the limiting groove 412a. The protrusion 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 rotating with the first gear 41 and the second gear 42 respectively.

[0044] like Figure 9 As shown, the gear set and motor 43 are arranged in a planar layout. When the motor 43 drives the rotating massage head 21 to reverse and retract, the rotating massage head 21 stops at the lowest position. At this time, the acupressure massage head 31 is also at the lowest position. With the help of foaming, the shoulder support surface can be made flat, avoiding the discomfort of the car seat.

[0045] In this embodiment, the forward and reverse rotation of the rotating massage head 21 are relative concepts. When forward rotation means clockwise rotation, reverse rotation means counterclockwise rotation, and vice versa. Therefore, regardless of 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 merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
