Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to an imitation acupressure massage mechanism. Background Art

[0002] In modern society, cars are not only essential for transportation but also a part of daily life. With rising living standards, people have higher expectations for car interior comfort. Passengers, in particular, often experience fatigue and discomfort from maintaining the same posture for extended periods during long journeys. Integrating massage chairs into car seats can effectively alleviate these issues.

[0003] Existing car seat massage systems often overlook the comprehensive needs of passengers in their designs, mostly providing massage functions only for the waist and back, while ignoring other fatigue-prone areas such as the shoulders. Most massages use air bag massage, which has a significant gap in strength and effectiveness compared to professional masseuses or advanced mechanical massage equipment. Furthermore, when integrating shoulder massage functions into car seats, there is a problem of finding a balance between appearance design and functionality. Utility Model Content

[0004] In view of this, the utility model provides an imitation acupressure massage mechanism, which aims to solve the problem that the car seat massage system lacks shoulder massage, and at the same time, can ensure the massage effect and take into account both functionality and appearance design.

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

[0006] A massage mechanism imitating acupressure comprises a support housing having an inner mounting hole, a massage head rotatably disposed in the inner mounting hole, a curved groove provided on a circumferential outer wall of the massage head, a guide protrusion provided on a wall of the inner mounting hole, the curved groove being slidably sleeved on the guide protrusion;

[0007] The bottom of the massage head is connected to a driving assembly for driving the massage head to rotate. During the process of the driving assembly driving the massage head to rotate, under the guidance and constraint of the curved groove and the guide protrusion, the massage head can be reciprocatedly ejected and retracted relative to the support shell.

[0008] By adopting the above structure, the massage head can be pushed out and retracted back and forth while rotating through the cooperation of the curved groove and the guide protrusion, providing a simulated acupressure shoulder massage. The mechanical structure effectively improves the massage effect and massage intensity compared to the air bag massage method.

[0009] Preferably, the device further comprises a base, upon which the support housing and drive assembly are assembled. When the guide protrusion is at the highest position of the curved groove, the massage head retracts into the support housing. With this structure, the massage head retracts when the massage mechanism is not in use, and the foaming process smoothes the shoulder rest surface, achieving both functionality and aesthetics.

[0010] Preferably, the massage head is a cylindrical structure, and the curved grooves are sinusoidal curves distributed along the circumference of the cylinder. With the above structure, the massage head can be regularly ejected and retracted, achieving a better massage effect.

[0011] As a preferred embodiment, the sine curves are in two groups and connected end to end to form a closed curved groove. With the above structure, the massage head can run stably and have a moderate massage rhythm.

[0012] As a preferred embodiment, a pin is inserted into the support shell, and the portion of the pin that protrudes beyond the inner wall of the support shell forms the guide protrusion.

[0013] As a preferred embodiment, two sets of guide protrusions are symmetrically provided on the hole wall of the support shell. With the above structure, the massage head is subjected to more balanced force and the reciprocating ejection and retraction are smoother.

[0014] Preferably, the drive assembly includes a transmission gear fixedly connected to the bottom of the massage head, and a motor mounted on the base, the motor being connected to the transmission gear via a reduction gear. With this structure, the motor drives the massage head, and power is transmitted to the transmission gear via the reduction gear. The rotation of the transmission gear drives the massage head.

[0015] Preferably, the transmission gear includes a rotating shaft extending axially upward, and the massage head includes a central inner hole that is sleeved on the rotating shaft. A protrusion adapted to fit within a retaining groove is provided on the sidewall of the central inner hole. The protrusion cooperates with the retaining groove to constrain the massage head from sliding up and down relative to the rotating shaft. This simple structure allows the massage head to rotate with the transmission gear while sliding up and down relative to the rotating shaft.

[0016] As a preferred embodiment, the upper end of the massage head is a curved surface with two protrusions provided on the curved surface. With the above structure, a simulated acupressure massage is achieved with good massage effect.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The simulated acupressure massage mechanism provided by the present invention can be used. While the driving assembly drives the massage head to rotate, the massage head can be reciprocatedly ejected and retracted relative to the support shell under the constraints of the guide protrusion and the sinusoidal groove on the side wall of the massage head, thereby imitating the effect of finger pressing massage.

[0019] 2. When the guide protrusion is at the highest position of the curved groove, the massage head is retracted into the supporting shell. Therefore, when the massage mechanism is not in use, it can cooperate with the foaming to make the surface of the shoulder support smooth, avoiding the nausea caused by the shoulder massage mechanism being integrated into the seat, while taking into account functionality and beautiful design.

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, a simulated acupressure massage mechanism utilizes a massage head 1. The upper end of the massage head 1 is curved, with two protrusions 12 provided on the curved surface. Protrusions 13 are used to simulate acupressure massage, achieving a more effective massage effect. The massage head 1 is rotatably mounted within a mounting bore 21 of a cylindrical support housing 2. The massage head 1 is cylindrical in structure. When the cylindrical side is unfolded into a rectangular plane, the curved groove 11 forms a sinusoidal curve. In this embodiment, the sinusoidal curve includes two periods, terminating at the cylindrical massage head 1. A guide protrusion 22 is provided on the wall of the mounting bore 21, and the curved groove 11 is slidably mounted on the guide protrusion 22.

[0027] like Figure 1 and Figure 4 As shown, the bottom of the massage head 1 is connected to a driving component 3 that drives it to rotate. During the process of the driving component 3 driving the massage head 1 to rotate, under the guidance and constraint of the sinusoidal groove 11 and the guide protrusion 22, the massage head 1 can be reciprocated relative to the supporting shell 2 to simulate acupressure massage. The mechanical structure is compared with the air bag massage method, and the massage effect and massage intensity are effectively improved.

[0028] In this embodiment, Figure 3As shown, two opposite pins are inserted into the support shell 2, and the portion of the pins extending beyond the inner wall of the support shell 2 constitutes the guide protrusion 22. With the support of the two pins, the massage head 1 can be smoothly and steadily ejected and retracted to avoid uneven force.

[0029] like Figure 2 and Figure 4 As shown, the massage mechanism also includes a base 4, and the support shell 2 and the drive assembly 3 are both assembled on the base 4. Since the support shell 2 is fixed, when the drive assembly 3 drives the massage head 1 to rotate, the massage head 1 is pushed out and retracted relative to the support shell 2. When the guide protrusion 22 is located at the highest position of the sinusoidal groove 11, the massage head 1 is retracted into the inside of the support shell 2. Combined with foaming, the shoulder support surface can be made smooth, avoiding the irritation caused by the integration of the shoulder massage mechanism on the seat, and taking into account both appearance design and functionality.

[0030] like Figure 4 As shown, the driving assembly 3 includes a motor 31 mounted on the base 4 and a transmission gear 32 fixed to the bottom of the massage head 1. The motor 31 is connected to the transmission gear 32 through a reduction gear 33. The reduction gear 33 is a gear set. The gear set transmits the power output by the motor 31 to the transmission gear 32. The transmission gear 32 has a rotating shaft 34 extending axially upward. The massage head 1 has a central inner hole sleeved on the rotating shaft 34. The side wall of the central inner hole is provided with a protruding structure adapted to the limiting groove 341. The protruding structure cooperates with the limiting groove 341 to constrain the massage head 1 to rotate relative to the rotating shaft 34. The axial movement between the massage head 1 and the rotating shaft 34 is not restricted. While the massage head 1 rotates with the rotating shaft 34, the curved groove 11 and the guide protrusion 22 constrain each other, and the massage head 1 moves up and down relative to the rotating shaft 34, so that the massage head 1 can simulate acupressure massage while rotating.

[0031] 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. Such changes fall within the scope of protection of the present invention.
