Technical Field

[0001] The utility model relates to a massage device. Background Art

[0002] As people's work intensity increases, white-collar workers in many cities need to work at desks for a long time, which causes neck pain. In severe cases, it can cause periarthritis of the shoulder. Therefore, in order to massage the shoulders after work, people have designed various massagers. However, the massage effect of the massagers in the prior art still cannot meet the demand, and the driving structure is relatively complicated. Utility Model Content

[0003] The purpose of the utility model is to overcome the defects of the prior art, and provide a massage device, which can simultaneously drive the massage head group and the massage arm group to swing up and down by a driving wheel.

[0004] The technical solution of the utility model is as follows: a massage device comprises a housing, two pairs of massage components distributed in an upper and lower manner, a motor is provided in the housing, a driving wheel is rotatably provided on both the left and right sides of the housing, the rotating shaft of the driving wheel is perpendicular to the output shaft of the motor in the front-back direction, an eccentric wheel is provided on the driving wheel, and an inclined wheel is also provided at the center of the driving wheel.

[0005] The first pair of massage components has massage head groups distributed on the left and right sides, and the two massage head groups are respectively installed on the inclined wheels on both sides. The second pair of massage components has massage arm groups distributed on the left and right sides, and the two massage arm groups are respectively installed on the eccentric wheels on both sides. When the motor drives the driving wheels on both sides to rotate synchronously through the worm gear mechanism, the two pairs of massage components will produce an up and down swinging massage action.

[0006] By adopting the above technical solution, the massage device of the utility model has a simple and reasonable structure, and adopts a worm gear mechanism to drive the driving wheels on both sides to rotate synchronously, with smooth transmission and low noise. The driving wheel is provided with an inclined wheel and an eccentric wheel at the same time, and the oblique wheel drives the massage head group to swing up and down, and the eccentric wheel drives the massage arm group to swing up and down, thereby achieving massage of the shoulders and neck and meeting the massage needs.

[0007] Preferably, each massage head assembly comprises a mounting plate and a massage head mounted on the mounting plate. The mounting plate is an inclined ring mounted on the bevel wheel. The mounting plate and the housing are engaged by a first slide groove and a protrusion. The first slide groove is arranged in the front-to-back direction, and the protrusion penetrates into the first slide groove to restrict the rotation of the mounting plate. The driving wheel drives the bevel wheel to rotate, which in turn drives the mounting plate to move. Since the mounting plate is mounted on the bevel wheel and penetrates into the first slide groove via the protrusion, the mounting plate is restricted from rotating, and the rotational motion is switched to a rocking motion.

[0008] Preferably, the inclined wheel has an inclined table and an inclined column located on the table. The mounting plate is sleeved outside the inclined column and pressed against the table through a pressing plate A. The pressing plate A and the inclined column are plugged in through an insert and a slot. The inclined wheel is also sleeved on the center platform of the driving wheel and positioned in the circumferential direction.

[0009] Preferably, there are two massage heads on each mounting plate, and the two massage heads are arranged in an upper and lower manner and staggered front to back. Compared with a single massage head, the massage area is wider, making the massage more comfortable.

[0010] Preferably, each massage arm assembly comprises a transmission sleeve, a transmission rod, and a massage arm. One end of the massage arm is hinged to the housing via a first connecting shaft, and the other end is a massage end. The transmission sleeve is mounted on an eccentric wheel. One end of the transmission rod is hinged to the connecting arm of the transmission sleeve via a second connecting shaft, and the other end is mounted to the middle portion of the massage arm via a third connecting shaft. The second connecting shaft is perpendicular to the output shaft of the motor in the front-to-back direction. The first connecting shaft, the third connecting shaft, and the output shaft of the motor are parallel to each other. The middle portion of the massage arm has a second slide groove, and the third connecting shaft slides through the second slide groove. The use of a hinged transmission rod mechanism facilitates the swinging of the massage arm. During use, the transmission sleeve is first driven by the eccentric wheel, and the connecting arm of the transmission sleeve rotates away from or toward the massage arm to pull back or push the transmission rod outward. As the third connecting shaft slides in the second slide groove, the massage arm is pulled to swing.

[0011] Preferably, the back of the driving wheel has the rotating shaft, and the rotating shaft is rotatably inserted into the plug column of the shell. The front of the driving wheel is integrally provided with an eccentric wheel and a center platform. The center platform is also protruding relative to the eccentric wheel. The center platform is provided for the inclined wheel to be mounted, and the eccentric wheel is provided for the transmission sleeve to be mounted. The outer diameter of the eccentric wheel is smaller than that of the driving wheel. The transmission sleeve is mounted on the outside of the eccentric wheel and is pressed against the driving wheel through the pressing piece B.

The mounting plate A1 is sleeved outside the inclined column 72 and pressed against the table 71 via a pressing piece A8. The pressing piece A8 and the inclined column 72 are plugged into each other via an insert a and a slot b. Specifically, there are two massage heads A2 on each mounting plate A1, and the two massage heads A2 are arranged in an upper and lower arrangement and are staggered front to back.

[0030] The second pair of massage components has massage arm groups B distributed on the left and right sides. The two massage arm groups B are respectively installed on the eccentric wheels 6 on both sides. Each massage arm group B has a transmission sleeve B1, a transmission rod B2 and a massage arm B3. One end of the massage arm B3 is hinged to the housing 1 through a connecting shaft B4, and the other end is a massage end. The transmission sleeve B1 is sleeved on the eccentric wheel 6. The upper end of the transmission rod B2 is hinged to the connecting arm B11 of the transmission sleeve B1 through a connecting shaft B5, and its lower end is hinged to the middle of the massage arm B3 through a connecting shaft B6. The connecting shaft B5 is perpendicular to the output shaft of the motor 3 in the front-to-back direction. The first shaft B4, the third connecting shaft B6, and the output shaft of the motor 3 are parallel to each other. The middle part of the massage arm B3 has a second slide groove B31. The third connecting shaft B6 is also slidably inserted into the second slide groove B31. The back of the driving wheel 4 has the rotating shaft 5. The rotating shaft 5 is rotatably inserted into the plug column of the housing 1, or the rotating shaft 5 is set on the housing.

The outer diameter of the eccentric wheel 6 is smaller than that of the driving wheel 4. The transmission sleeve B1 is sleeved outside the eccentric wheel 6 and is pressed against the driving wheel 4 through the pressing piece B9.

[0031] When the motor 3 drives the driving wheels 4 on both sides to rotate synchronously through the worm gear mechanism, the two pairs of massage components produce a massage action of swinging up and down.

[0032] Specifically, the shell 1 includes an inner shell 1a and an outer shell 1b, the inner shell 1a has a accommodating space A composed of an inner shell seat 1a1 and an inner front cover 1a2, the inner shell seat 1a1 and the inner front cover 1a2 are connected by snaps or screws, the outer shell 1b has a accommodating space B composed of an outer shell seat 1b1 and an outer front cover 1b2, the outer shell seat 1b1 and the outer front cover 1b2 are connected by snaps or screws, the motor 3 and the driving wheel 4 are both located in the accommodating space A, and the driving wheel 4 is rotatably mounted on the inner shell seat 1a1, the inner shell 1a and the power supply 10 are installed together in the accommodating space B, the motor is powered by the power supply 10, a circuit board is also provided in the accommodating space B, and the inner front cover 1a2 and the outer front cover 1b2 are both provided with an exposed opening for the massage component to pass through.

[0033] The working principle of the utility model is as follows: when in use, the double-headed motor 3 drives the driving wheels 4 on both sides to rotate synchronously through the worm gear mechanism.

Since the mounting plate A1 is mounted around the inclined wheel 7 and also penetrates into the slide groove A3 via the protrusion A4, the mounting plate A1 is restricted from rotating and the rotational motion is switched to a rocking motion.

[0035] The drive wheel 4 rotates the eccentric wheel 6, which in turn drives the transmission sleeve B1. This causes the connecting arm B11 of the transmission sleeve B1 to rotate away from or toward the massage arm B3, pulling back or pushing the transmission rod B2. As the connecting shaft B6 slides in the second guide groove B31, the massage arm B3 swings about the hinge axis AB4. The transmission sleeve B1 can also rotate relative to the eccentric wheel 6.
