Description

Technical Field

[0001] The utility model belongs to the field of massage equipment, and in particular relates to a device with changeable massage actions. Background Art

[0002] Most existing massagers feature multiple massage heads with different orientations. These heads swing in coordination, producing various massage movements on the neck and shoulders, such as hammering, pinching, kneading, and pinching. The massage heads are mounted on the massager body close to the neck and shoulders. Their mounting position doesn't change as the massage action is completed, nor does the massage posture. If the massager is used on a pillow, the heads will constantly press against the neck and shoulders, making it difficult to lie flat. This same problem also occurs with massagers used on seats. Utility Model Content

[0003] The purpose of the utility model is to provide a massage device which can adapt to the massage posture required by massage carriers such as pillows and seats in a changing manner.

[0004] The variable massage device includes a machine box, a massage drive motor and a conversion drive motor. A pair of neck massage heads are built into the middle of the machine box and are spaced apart along the longitudinal direction of the machine box. Each neck massage head is correspondingly provided with a shoulder massage head arranged along the transverse direction of the machine box. The neck massage heads and shoulder massage heads generate massage movements through the massage drive motor. The conversion drive motor enables the neck massage heads and shoulder massage heads to rotate relative to the machine box and rotate until they are retracted into the machine box.

[0005] The machine box is provided with an escape groove for the rotation of the neck massage head and a yield groove for the rotation of the shoulder massage head.

[0006] The machine box is composed of a bottom shell and a panel, the panel is composed of a concave plate in the middle and cover plates at both ends, the concave plate and the cover plate are spliced ​​together through a notch to form an air avoidance groove, and the side plate of the bottom shell and the concave plate are spliced ​​together through the notch to form a clearance groove.

[0007] The cover plate is driven by a lifting drive motor to perform lifting motion, and the lifting drive motor is built in the machine box.

[0008] Both ends of the massage drive motor are connected to a cam connecting rod mechanism for swinging the neck massage head and the shoulder massage head through a worm respectively.

[0009] The cam-link mechanism includes a pair of horizontally placed meshing gears, one of which is coaxially mounted with a worm wheel assembled with the worm, and the other gear is coaxially mounted with a cam and an oblique cam in sequence above it, the oblique cam abuts against a connecting arm, and neck massage heads of different heights are provided on both sides of the connecting arm, the cam is built into an eccentric wheel, the eccentric wheel is connected to a rocker arm, and the rocker arm is connected to the shoulder massage head through a hanging ear.

[0010] The conversion drive motors are respectively connected to the lifting ears along the longitudinal direction and to the connecting arms along the transverse direction.

[0011] The conversion drive motor is a carbon brush reduction motor.

[0012] The beneficial effects of the present invention are as follows: the neck massage head and the shoulder massage head are rotated and retracted into the machine box by utilizing the conversion drive motor, thereby changing the installation position of the neck massage head to accommodate more massage postures; the lifting and lowering movement of the cover plate not only can adjust the height of the massage part, but also realizes the synchronization of massage and lifting, thereby increasing comfort.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 、 2 As shown in Figure 3, the variable massage device uses a machine box as a protective cover. Inside the machine box, a lifting drive motor 1, a gear box (with a side bevel gear 2, an upper bevel gear 2', and a screw 3) are installed in sequence along the longitudinal direction. The neck massage head 4, a cam connecting rod mechanism (connected to a horizontally mounted shoulder massage head 5), a massage drive motor 6, a cam connecting rod mechanism (connected to a horizontally mounted shoulder massage head 5), the neck massage head 4, a gear box (with two bevel gears 2 and a screw 3), and the lifting drive motor 1 are arranged symmetrically. The lifting drive motor, gear box, neck massage head, and cam connecting rod mechanism (connected to a horizontally mounted shoulder massage head) are arranged symmetrically. The machine box is composed of a bottom shell 7 and a panel 8. The panel 8 is composed of a concave plate 9 in the middle and cover plates 10 at both ends. The concave plate 9 and the cover plate 10 are spliced ​​together through a notch to form an air-avoidance groove 11. The side plates of the bottom shell 7 and the concave plate 9 are spliced ​​together through a notch to form a clearance groove 12.

[0018] A pair of horizontally positioned meshing gears, a worm gear, a cam, a helical cam, and an eccentric wheel form a cam-link mechanism. Worms 13 are located at each end of the massage drive motor 6. Each worm 13 meshes with a corresponding pinion 14, which is coaxially mounted with a worm wheel 15, which is located below the pinion 14. A cam 17 and a helical cam 18 are coaxially mounted above a large gear 16. The helical cam 18 abuts a connecting arm 19, which is flanked by neck massage heads 4 at varying heights. This connecting arm 19 is laterally connected to the drive shaft of a conversion drive motor 20. Cam 17 is embedded in an eccentric wheel 21, which is connected to a rocker arm 22. This rocker arm 22 is connected to the shoulder massage head 5 via a lug 23, which is longitudinally connected to the drive shaft of the conversion drive motor 20. The conversion drive motor is a brushless reduction motor with a reduction ratio of 1:515, a voltage of 12V, and a motor speed of 30,000 ± 10%.

[0019] The massage drive motor 6 rotates the worm 13, which in turn drives the worm gear 15. The worm gear 15 drives the pinion 14 to rotate coaxially. The pinion 14, through a gear transmission, drives the large gear 16. The large gear 16 drives the cam 17 and the inclined cam 18 to rotate coaxially. The cam 17 drives the eccentric 21, which in turn drives the rocker arm 22 to move left and right and back and forth. This rocker arm drives the shoulder massage head to perform a left-right and back-and-forth massage action. Simultaneously, the inclined cam 18 drives the connecting arm 19 to move up and down and left and right, which in turn drives the neck massage head to perform a left-right and back-and-forth massage action. When the shoulder and neck massage heads begin massaging, they can also perform a simultaneous lifting and lowering massage action. The lifting drive motor 1 drives the side bevel gear 2 to rotate longitudinally, and the side bevel gear 2 drives the upper bevel gear 2' to rotate. The upper bevel gear 2' is placed horizontally and is threadedly connected to the vertically placed screw 3. The upper bevel gear 2' and the screw 3 are driven by a spiral transmission to make the screw 3 move up and down. The top end of the screw 3 pushes the cover plate 10 through the horizontal pad 24 to perform a lifting and massaging action.

[0020] When the shoulder and neck massage heads stop massaging, each conversion drive motor is activated. The conversion drive motor 20 drives the connecting arm 19 to rotate longitudinally, which drives the neck massage head 4 to retract from the clearance slot 11 into the housing. The conversion drive motor 20 drives the lifting lug 23 to rotate horizontally, which drives the shoulder massage head 5 to retract from the clearance slot 12 into the housing. At this time, for massage carriers such as pillows and seats, there is no uneven contact between the shoulder and neck massage heads. People can lie comfortably on the pillow or lean comfortably against the seat. They can also independently perform the lifting and lowering massage action like the above-mentioned cover plate, thereby adapting to and expanding more massage postures and meeting different massage needs.
