Description

Technical Field

[0001] This utility model relates to the field of massage backrest technology, and in particular to a rotary swing massage mechanism. Background Technology

[0002] As the name suggests, a massage chair is a chair that can massage the human body. The main massage area is located in the backrest. Traditional massage chairs usually use massage balls to knead the user's back while they are leaning against the chair. This massage method only massages certain areas, resulting in a small massage coverage area. Existing massage backrests on the market have a walking mechanism and rotating massage heads. During use, the rotating massage heads continuously rotate, massaging the back. Driven by the walking mechanism, the massage heads repeatedly move up and down, allowing for full coverage massage from the waist to the neck. However, because the massage heads cannot move laterally, they always move back and forth in a straight line, resulting in incomplete massage coverage and limited massage comfort. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotary swing massage mechanism that can move laterally back and forth and can continuously rotate and massage while moving back and forth.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rotary oscillating massage mechanism, comprising a base shell, a rotary massage head, a drive wheel mounted on the base shell, and a drive mechanism for driving the drive wheel. The base shell is equipped with a driven wheel that rotates synchronously with the drive wheel and a connecting shaft. The connecting shaft is movably mounted with an oscillating frame, an oscillating wheel and a swing rod movably mounted on the outer end of the oscillating frame. The oscillating wheel meshes with the driven wheel for transmission. An eccentric column is mounted on the outer side of the drive wheel. A connecting rod is movably mounted between the eccentric column and the other end of the swing rod. The rotary massage head is coaxially and fixedly connected to the oscillating wheel.

[0005] Preferably, the bottom shell has a sliding groove, and one end of the swing rod is provided with a protrusion, which is movably embedded in the sliding groove.

[0006] Preferably, the swing frame is movably equipped with a rotating shaft, and the swing wheel and the rotating massage head are both fixedly connected to the rotating shaft.

[0007] Preferably, the swing frame is an "8"-shaped housing, and the driven wheel and the swing wheel are arranged inside the "8"-shaped housing.

[0008] Preferably, the swing frame is fixedly equipped with at least two conductive rings, and the rotating massage head includes a massage turntable fixedly connected to the rotating shaft, a massage ball disposed on the outer surface of the massage turntable, an actuator installed in the massage turntable, and at least two conductive spring pins movably installed in the massage turntable. The conductive spring pins slide against the conductive rings, and the actuator and the conductive spring pins are electrically connected through a wire.

[0009] Preferably, the actuator is an electric heating element and / or a vibration motor.

[0010] Preferably, the heating element is a heating wire or a heating lamp.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a rotary swing massage mechanism. In practical applications, the rotary swing massage mechanism is installed on a track support. Under the action of the walking mechanism, the mechanism moves up and down along the track support. When the drive wheel rotates under the action of the drive mechanism, it drives the swing wheel and the rotating massage head to rotate synchronously. Due to the design of the swing wheel and the linkage structure, the outer end of the swing frame swings laterally back and forth, thereby realizing the lateral back and forth movement of the rotating massage head. This achieves the function of both lateral back and forth movement and continuous rotation massage while moving back and forth. Attached Figure Description

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figures 1 to 5As shown, a rotary oscillating massage mechanism includes a base shell 11, a rotary massage head 2, a drive wheel 12 mounted on the base shell 11, and a drive mechanism for driving the drive wheel 12. The base shell 11 is equipped with a driven wheel 13 that rotates synchronously with the drive wheel 12 and a connecting shaft 14. The connecting shaft 14 is movably equipped with an oscillating frame 15, an oscillating wheel 16 movably mounted on the outer end of the oscillating frame 15, and a swing rod 10. The oscillating wheel 16 meshes with the driven wheel 13 for transmission. An eccentric column 17 is mounted on the outer side of the drive wheel 12. A connecting rod 18 is movably mounted between the eccentric column 17 and the other end of the swing rod 10. The rotary massage head 2 is coaxially and fixedly connected to the oscillating wheel 16.

[0019] In practical applications, the rotary oscillating massage mechanism is mounted on a track support. Under the action of the walking mechanism 3, the mechanism moves up and down along the track support. When the drive wheel 12 rotates under the action of the drive mechanism, it drives the oscillating wheel 16 and the rotary massage head 2 to rotate synchronously. Due to the design of the structure of the oscillating wheel 16 and the connecting rod 18, the outer end of the oscillating frame 15 swings laterally back and forth, thereby realizing the lateral back and forth movement of the rotary massage head 2. It can achieve the function of both lateral back and forth movement and continuous rotation massage while moving back and forth, which is highly practical.

[0020] In this embodiment, the bottom shell 11 is provided with a sliding groove 1A, and one end of the swing rod 10 is provided with a protrusion 1B. The protrusion 1B is movably embedded in the sliding groove 1A. The swing rod 10, connecting rod 18, swing frame 15 and drive wheel 12 are combined to form a movable quadrilateral structure. Utilizing the limiting effect of the sliding groove 1A and the protrusion 1B, under the drive of the drive wheel 12, the various components work together to effectively ensure that the swing wheel 16 and the rotating massage head 2 move back and forth along the sliding groove 1A, resulting in high structural reliability.

[0021] In this embodiment, the swing frame 15 is movably equipped with a rotating shaft 19, and the swing wheel 16 and the rotating massage head 2 are both fixedly connected to the rotating shaft 19. The rotating shaft 19 ensures that the rotating massage head 2 always rotates synchronously with the swing wheel 16 to achieve the massage effect, reduce the assembly complexity of the swing frame 15, and improve the assembly efficiency.

[0022] In this embodiment, the swing frame 15 is an "8"-shaped housing, and the driven wheel 13 and the swing wheel 16 are arranged inside the "8"-shaped housing. The smooth housing design and the gear assembly are wrapped inside the housing, which effectively avoids pinching the skin or clothing during use and further improves safety and reliability.

[0023] In this embodiment, the swing frame 15 is fixedly equipped with at least two conductive rings 25. The rotating massage head 2 includes a massage disc 21 fixedly connected to the rotating shaft 19, massage balls 22 disposed on the outer surface of the massage disc 21, an actuator 23 installed inside the massage disc 21, and at least two conductive spring pins 24 movably installed inside the massage disc 21. The conductive spring pins 24 slide against the conductive rings 25, and the actuators 23 are electrically connected to the conductive spring pins 24 via wires. Due to the structural design of the conductive spring pins 24 and the conductive rings 25, communication or power transmission between the main body of the mechanism and the actuators 23 can still be achieved during the continuous rotation of the rotating massage head 2, realizing the synchronous massage effect of the actuators 23, which is highly practical.

[0024] In this embodiment, the actuator 23 is an electric heating element and a vibration motor. The electric heating element is used to realize the hot compress massage of the massage area, and the vibration motor drives the rotating massage head 2 to vibrate to realize the vibration massage of the massage area, reducing the friction and epidermal damage generated when the massage ball 22 is massaged on the skin surface, and further improving comfort.

[0025] In this embodiment, the heating element is a heating wire, which allows for control of the heating temperature or adjustment of the heating level by adjusting the voltage or current, making it simple and practical. Of course, this heating wire can also be replaced with a heating lamp, achieving the same technical effect.
