Description

Technical Field

[0001] This utility model relates to the technical field of massagers, and in particular to a massager mechanism and its massage arm. Background Technology

[0002] In modern society, people spend long hours sitting at work in offices, classrooms, and dormitories or homes using computers and mobile phones, day after day, inevitably leading to many suffering from cervical spondylosis and frozen shoulder. Shoulder strap massagers, designed to massage the neck and shoulders, have emerged as a solution. These massagers primarily target the user's neck and shoulder area. During use, a drive mechanism provides mechanical energy to the massage components, enabling them to rhythmically rotate, swing, vibrate, and tap to relax muscles, improve blood circulation in the neck and shoulders, and relieve symptoms such as stiffness and pain.

[0003] One existing type of shoulder and neck massager uses a single-axis output motor to simultaneously drive two sets of transmission gears on the left and right sides. These two sets of transmission gears then drive the massage components to massage the shoulders and neck. This type of massager is prone to uneven bearing load due to unilateral force on the motor. Furthermore, to ensure the massage effect, the two sets of transmission gears need to be designed with multi-stage transmission. The increased number of gears will aggravate meshing impact and the accumulation of backlash error, resulting in high-frequency vibration and noise, and high maintenance and replacement costs. Moreover, it requires a sufficiently large installation space for the gear sets, resulting in a large overall size of the massager and failing to meet the requirements for miniaturization and portability.

[0004] Another type of shoulder and neck massager uses a single-axis output motor to drive a gear set, which in turn drives the main shaft of the mechanism. Eccentric wheel assemblies are symmetrically mounted at both ends of the main shaft, with a shoulder massage component and a neck massage component mounted on each eccentric wheel assembly. Through the action of the main shaft and the eccentric wheels, the shoulder and neck massage components on both sides of the main shaft perform a massage, achieving a kneading massage effect on the shoulders and neck. This type of shoulder and neck massager also suffers from problems such as large size, high vibration and noise, and uneven bearing load due to unilateral motor force.

[0005] In view of this, this utility model is developed by deeply conceiving and actively researching, improving and testing the design of existing shoulder and neck massage mechanisms to address the many shortcomings and inconveniences caused by their imperfections. Utility Model Content

[0006] The purpose of this invention is to overcome the problems of large size and uneven bearing load in the existing technology of massage mechanism, and to provide a shoulder and neck massage mechanism with compact structure, relatively small size, low vibration and noise, and stable and smooth massage.

[0007] To achieve the above objectives, the solution of this utility model is:

[0008] A shoulder and neck massage mechanism includes a housing, a drive motor, two sets of transmission mechanisms, two sets of first massage components, and two sets of second massage components. The drive motor is installed in the middle of the housing, and an output shaft is provided on each of the left and right sides of the drive motor. The two sets of transmission mechanisms are correspondingly connected to the output shafts on the left and right sides of the drive motor. Each output shaft is respectively connected to a set of first massage components and a set of second massage components. An eccentric wheel is provided on the transmission mechanism. The first massage component has a massage arm and a first massage head. The bottom end of the massage arm is connected to the eccentric wheel, and the top end of the massage arm extends out of the housing and connects to the first massage head. The second massage component includes a connector, a linkage mechanism, and a second massage head. One end of the connector is connected to the eccentric wheel, and the other end of the connector is connected to one end of the linkage mechanism. The other end of the linkage mechanism forms a first branch and a second branch. The first branch extends obliquely out of the housing and connects to the second massage head, so that the first massage head and the second massage head form an angle. The second branch is hinged to the housing. A limiting groove is provided on the side of the housing corresponding to the linkage mechanism for the linkage mechanism to move up and down.

[0009] Furthermore, the first massage component also includes a swing seat and a connecting shaft. The swing seat is mounted on an eccentric wheel and has a swing inclined surface with its upper end face inclined to the eccentric wheel, as well as a through hole perpendicular to the swing inclined surface. The eccentric wheel has a groove corresponding to the through hole, and the bottom end of the connecting shaft passes through the through hole of the swing seat and fits into the mounting groove of the eccentric wheel.

[0010] Furthermore, the bottom of the swing seat is provided with two limiting posts spaced apart, and the eccentric wheel is provided with limiting holes corresponding to the two limiting posts. The swing seat is fixedly installed on the eccentric wheel, and the top end of the connecting shaft is inserted into the swing seat to connect the swing seat and the massage arm together.

[0011] Furthermore, the bottom of the massage arm is provided with a swing ball head installed on the swing inclined surface of the swing seat, and pins extend outward from the two opposite sides of the swing ball head. The inner top surface of the housing is provided with a ball socket and a pin hole corresponding to the swing ball head and the pin. The swing ball head is installed in the ball socket of the housing, and the pin is installed in the pin hole.

[0012] Furthermore, the eccentric seat has an eccentric inclined surface located near the edge of the eccentric seat and tilts downwards from the center to the edge, so that the massage arm mounted on the eccentric inclined surface always tilts outwards.

[0013] Furthermore, the top of the eccentric wheel forms a constriction, and the connector of the second massage component is a hollow collar with an extension arm at one end. The hollow collar is fitted onto the constriction of the eccentric wheel, and the eccentric swing seat is installed behind the eccentric wheel to fix the hollow collar onto the eccentric wheel.

[0014] Furthermore, the linkage mechanism includes a first link, a second link, and a third link. One end of the first link is hinged to the extension arm of the connector, and the other end of the first link is hinged to one end of the second link. The middle part of the third link is hinged to the other end of the second link. One end of the third link forms the first branch, and the other end of the link forms the second branch.

[0015] Furthermore, the two output shafts of the drive motor are respectively equipped with helical teeth, and the transmission mechanism includes a double gear and a massage gear. One gear of the double gear meshes with the helical teeth of the output shaft of the drive motor, and the other gear of the double gear meshes with the massage gear. The massage gear is fixedly equipped with the eccentric wheel. When the drive motor is running, it drives the two output shafts to rotate. The helical teeth on the two output shafts drive the double gear meshing with them to rotate. The double gear drives the massage gear to rotate, which in turn drives the eccentric wheel on the massage gear to rotate.

[0016] Furthermore, the housing includes an upper shell and a lower shell, with a motor cavity located at the center of the upper shell and the lower shell, and the drive motor is installed in the motor cavity.

[0017] With the above structure, when the shoulder and neck massager of this utility model is running, the output shafts at both ends of the drive motor simultaneously drive the two sets of transmission mechanisms to rotate. The transmission mechanisms drive the eccentric wheel, massage arm and connecting parts to rotate synchronously, so that the first massage head installed on the massage arm rotates under the action of eccentricity. At the same time, the connecting parts drive the linkage mechanism to move. The linkage mechanism is limited by the second branch hinged to the housing and the limiting groove, which converts the rotational movement into an up and down movement, thereby driving the second massage head to move up and down. When the second massage head moves up, it cooperates with the first massage head to clamp the shoulder and neck. When the second massage head moves down, it relaxes the shoulder and neck. Through the cooperation of the first massage head and the second massage head, a kneading massage of the shoulder and neck is achieved.

[0018] This invention uses a dual-output drive motor to simultaneously drive the left and right first and second massage components. The power distribution at both ends is balanced, which can reduce vibration and noise. Furthermore, the transmission mechanism can be designed with a smaller number of gear sets to avoid efficiency loss. At the same time, it can save installation space for the transmission mechanism, making the housing design more compact, saving space and cost, and making the entire massage core structure more compact and small, which can meet the needs of miniaturization and portability. It also operates stably and provides a good massage experience. Attached Figure Description

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] like Figures 1 to 7As shown, this utility model discloses a shoulder and neck massage mechanism, which includes a housing 1, a drive motor 2, two sets of transmission mechanisms 3, two sets of first massage components 4, and two sets of second massage components 5. The drive motor 2 is installed in the middle of the housing 1, and an output shaft 21 is provided on the left and right sides of the drive motor 2, respectively. The two sets of transmission mechanisms 3 are correspondingly connected to the output shafts 21 on the left and right sides of the drive motor 2. Each output shaft 21 corresponds to a set of first massage components 4 and a set of second massage components 5. An eccentric wheel 31 is provided on the transmission mechanism 3. The first massage component 4 has a massage arm 42 and a first massage head 43. The bottom end of the massage arm 42 is connected to the eccentric wheel 31. The top extends out of the housing 1 and connects to the first massage head 43. The second massage assembly 5 includes a connector 51, a linkage mechanism 52 and a second massage head 53. One end of the connector 51 is connected to the eccentric wheel 31, and the other end of the connector 51 is connected to one end of the linkage mechanism 52. The other end of the linkage mechanism 52 forms a first branch 521 and a second branch 522. The first branch 521 extends obliquely out of the housing 1 and connects to the second massage head 53, so that the first massage head 43 and the second massage head 53 form an angle. The second branch 522 is hinged to the housing 1. A limiting groove 11 is provided on the side of the housing 1 corresponding to the linkage mechanism 52 for the linkage mechanism 52 to move up and down.

[0031] When the drive motor 2 is running, the output shafts 21 at both ends of the drive motor 2 simultaneously drive the two transmission mechanisms 3 to rotate. The transmission mechanisms 3 drive the eccentric wheel 31, the massage arm 42 and the connecting piece 51 to rotate synchronously, so that the first massage head 43 installed on the massage arm 42 rotates under the action of eccentricity. At the same time, the connecting piece 51 drives the linkage mechanism 52 to move. The linkage mechanism 52 is limited by the limiting effect of the second branch 522 hinged to the housing 1 and the limiting groove 11, which converts the rotational movement into an up-and-down movement, thereby driving the second massage head 53 to move up and down. When the second massage head 53 moves up, it cooperates with the first massage head 43 to clamp the shoulders and neck. When the second massage head 53 moves down, it relaxes the shoulders and neck. The kneading massage of the shoulders and neck is achieved through the cooperation of the first massage head 43 and the second massage head 53.

[0032] This utility model uses a dual-output drive motor 2 to simultaneously drive the two sets of first massage components 4 and second massage components 5 on the left and right sides. The power distribution at both ends is balanced, which can reduce vibration and noise. Furthermore, the transmission mechanism 3 can be designed with a smaller number of gear sets to avoid efficiency loss. At the same time, it can save the installation space of the transmission mechanism 3, making the housing 1 more compact, saving space and cost, and making the structure of the entire massage core more compact and small, which can meet the needs of miniaturization and portability.

[0033] like Figure 7As shown, the shoulder and neck massager housing 1 of this utility model includes an upper shell 12 and a lower shell 13. A motor cavity 14 is provided at the center of the upper shell 12 and the lower shell 13, and the drive motor 2 is installed in the motor cavity 14.

[0034] like Figure 4 As shown in this embodiment, the two output shafts 21 of the drive motor 2 are respectively equipped with helical teeth. The transmission mechanism 3 includes a double gear 32 and a massage gear 33. One gear of the double gear 32 meshes with the helical teeth of the output shaft 21 of the drive motor 2, and the other gear of the double gear 32 meshes with the massage gear 33. The massage gear 33 is fixedly provided with the eccentric wheel 31. When the drive motor 2 is running, it drives the two output shafts 21 to rotate. The helical teeth on the two output shafts 21 drive the double gear 32 that is meshed to rotate. The double gear 32 drives the massage gear 33 to rotate, which in turn drives the eccentric wheel 31 on the massage gear 33 to rotate.

[0035] like Figure 5 As shown, the first massage component 4 also includes a swing seat 41 and a connecting shaft 44. The swing seat 41 is mounted on the eccentric wheel 31. The swing seat 41 has a swing inclined surface 411 with its upper end face inclined to the eccentric wheel 31, and a through hole 412 perpendicular to the swing inclined surface 411. The eccentric wheel 31 has a corresponding inclined groove 311 for the through hole 412. The bottom end of the connecting shaft 44 passes through the through hole 412 of the swing seat 41 and fits into the mounting groove of the eccentric wheel 31. The bottom of the swing seat 41 is also provided with two limiting posts 413 spaced apart. The eccentric wheel 31 has limiting holes 312 corresponding to the two limiting posts 413, and can be locked with screws, thereby fixing the swing seat 41 on the eccentric wheel 31. The top end of the connecting shaft 44 is inserted into the eccentric seat 41, thereby connecting the eccentric wheel 31, the eccentric seat 41 and the massage arm 42 together. The bottom of the massage arm 42 is provided with an eccentric ball head 421 installed on the eccentric inclined surface 411 of the eccentric seat 41. Pins 422 extend outward from the two opposite sides of the eccentric ball head 421. The inner top surface of the housing 1 is provided with a ball socket 15 and a pin hole 16 corresponding to the eccentric ball head 421 and the pin 422. The eccentric ball head 421 is installed in the ball socket 15 of the housing 1 and the pin 422 is installed in the pin hole 16, so that the massage arm 42 performs an eccentric rotation action under the rotation of the eccentric seat 41 and the eccentric wheel 31.

[0036] Preferably, the eccentric seat's eccentric inclined surface 411 is located near the edge of the eccentric seat and slopes downward from the center to the edge, so that the massage arm 42 mounted on the eccentric inclined surface 411 always tilts outward.

[0037] When the first massage component 4 is installed, the swing seat 41 is fixed on the eccentric wheel 31, and the swing ball head 421 of the massage arm 42 is installed on the swing seat 41. The swing seat 41, the eccentric wheel 31 and the massage arm 42 are connected by a connecting shaft 44. The swing ball head 421 of the massage arm 42 is limited in the ball socket 15 of the housing 1, and the pin 422 is limited in the pin hole 16. When the eccentric wheel 31 rotates, the massage arm 42 rotates relative to the eccentric seat around the connecting shaft 44. The massage arm 42 drives the first massage head 43 to rotate and swing back and forth and left and right, thereby improving the massage comfort.

[0038] like Figure 5 As shown, the top of the eccentric wheel 31 forms a constriction. The connector 51 of the second massage component 5 is a hollow collar 512 with an extension arm 511 at one end. The hollow collar 512 is fitted onto the constriction of the eccentric wheel 31. After the eccentric swing seat 41 is installed on the eccentric wheel 31, the hollow collar 512 can be fixed on the eccentric wheel 31.

[0039] In this embodiment, the linkage mechanism 52 includes a first link 523, a second link 524, and a third link 525. One end of the first link 523 is hinged to the extension arm 511 of the connector 51, and the other end of the first link 523 is hinged to one end of the second link 524. The middle part of the third link 525 is hinged to the other end of the second link 524. One end of the third link 525 forms the first branch 521, and the other end forms the second branch 522. The linkage mechanism 52 converts the rotational motion of the eccentric wheel 31 into the up-and-down swinging motion of the second massage head 53, which, in conjunction with the first massage head 43, achieves the clamping or relaxing of the shoulders and neck.

[0040] When the shoulder and neck massager of this utility model is in operation, the drive motor 2 drives the transmission mechanism 3 and the eccentric wheel 31 connected to the transmission mechanism 3 to rotate. The eccentric wheel 31 can simultaneously drive the first massage component 4 and the second massage component 5 to move, so that the first massage head 43 and the second massage head 53 move at the same time to knead and massage the shoulders and neck. The entire massager has a simple and compact structure, which can make the first massage component 4 and the second massage component 5 on both sides move in unison. The first massage head 43 adopts a swaying rotation to massage, which can greatly increase the massage area. In addition, the clamping and releasing action of the second massage head 53 can simulate human hand massage and improve massage comfort.

[0041] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
