Description

Technical Field

[0001] This invention relates to the field of massage technology, and more particularly to a massager. Background Technology

[0002] Massagers relieve fatigue by massaging the body and are common items in daily life. Common massagers range from large, immobile massage chairs to smaller massage sticks or neck and shoulder massagers. Neck and shoulder massagers, in particular, are attached to the back of the neck via straps and automatically massage the sides of the neck, shoulders, and back. They offer a variety of massage movements and are especially popular with consumers, particularly office workers who suffer from neck and shoulder fatigue due to prolonged sitting. Neck and shoulder massagers have massage structures positioned on both sides of the device. Each massage structure includes a shoulder massage head (which can be considered the upper massage head) and a back massage head (which can be considered the lower massage head). The shoulder massage heads massage the neck and shoulders in an arc, while the back massage heads massage the back in a reciprocating linear motion. Existing massagers have separate drive modules for the shoulder massage head and the back massage head, resulting in a complex internal structure and poor synchronization of shoulder and back massage. In addition, with the increase of usage time, the repeated sliding friction between the components of the swing arm structure causes a decrease in the accuracy of the limit, and the swing arm structure may become loose or the running trajectory may deviate. Especially for the shoulder massage head, the massage head may vibrate jumpingly, that is, the shoulder massage head may deviate from the massage trajectory. Summary of the Invention

[0003] This invention provides a massager that simplifies the drive module and improves massage stability.

[0004] The technical solution adopted in this invention is as follows:

[0005] A massager includes a housing, a drive module installed inside the housing, and massage structures connected to the two ends of the drive module. The drive module includes a motor and turntables installed at both ends of the motor. The motor drives the turntables at both ends to rotate, and the massage structures at both ends are respectively connected to the turntables at the corresponding ends.

[0006] Each massage structure includes an upper swing arm structure, an upper massage head connected to the upper swing arm structure, a lower swing arm structure, and a lower massage head connected to the lower swing arm structure, with a connecting body formed on the turntable component;

[0007] The upper swing arm structure includes an upper swing arm push rod, a ball-head swing rod, and a ball-head guide seat. One end of the upper swing arm push rod is rotatably sleeved on the connecting body, and the other end forms a swing groove.

[0008] The ball head rocker includes a spherical part, an upper rod section formed at the upper end of the spherical part, and a lower rod section formed at the lower end of the spherical part. The spherical part is housed in a ball head guide seat, and its lifting and lowering are restricted by the ball head guide seat. The upper rod section extends out of the ball head guide seat and is connected to the upper massage head. The end of the lower rod section is oscillatingly connected to the rocker groove.

[0009] The upper arm push rod moves in a circular motion under the drive of the turntable. The other end of the push rod drives one end of the ball head rocker arm to make a corresponding arc motion on the plane. The other end of the ball head rocker arm swings around the spherical part as the pivot point, so that the upper massage head moves in a corresponding arc massage trajectory.

[0010] The lower arm structure includes a lower arm push rod, a push connecting assembly, and a swing arm. One end of the lower arm push rod is rotatably sleeved on the connecting body, and the other end is rotatably connected to the push connecting assembly. One end of the swing arm is hinged to the housing, and the other end is rotatably connected to one end of the swing connecting assembly. The swing arm is equipped with the lower massage head.

[0011] One end of the lower swing arm push rod moves in a circular motion under the drive of the turntable component, pushing and pulling the push connection assembly. The push connection assembly pulls the swing arm to swing repeatedly around the hinge point with the housing.

[0012] Furthermore, a clamping wall is formed opposite to each other in the swing groove, and a horizontal column is formed at the end of the lower rod section. The two ends of the horizontal column are formed opposite to each other with abutting end faces for cooperating with the clamping wall.

[0013] Furthermore, the ball head guide seat includes an upper ball shell seat and a lower ball shell seat. The upper ball shell seat has an upper hemisphere protruding on it, and the lower ball shell seat has a lower hemisphere concave on it. The upper ball shell seat and the lower ball shell seat are combined to form a spherical groove for accommodating the spherical part. The upper hemisphere has an upper through hole for the upper rod section to pass through, and the lower ball shell seat has a lower through hole for the lower rod section to pass through.

[0014] Furthermore, the horizontal push connection assembly includes a horizontal swing connector and a vertical swing connector. One end of the horizontal swing connector is equipped with a longitudinal pin parallel to the connecting body, and the other end is equipped with a transverse pin perpendicular to the longitudinal pin. The lower swing arm push rod is hinged to the horizontal swing connector through the longitudinal pin. One end of the vertical swing connector is hinged to the horizontal swing connector through the transverse pin, and the other end of the vertical swing connector is hinged to the swing arm through another transverse pin.

[0015] Furthermore, the drive module includes a transmission assembly, which includes a gear column structure, a positioning gear, and a transmission column. The motor is a dual-axis worm motor. The gear column structure includes a gear column, a main gear and a secondary gear fixedly mounted on the gear column. The main gear meshes at a right angle with the worm of the motor, and the secondary gear meshes with the positioning gear. The transmission column is coaxially mounted at the center of the positioning gear, and a turntable is fixedly mounted on the top surface of the transmission column.

[0016] Furthermore, the housing includes an upper housing, with mounting grooves at both ends of the upper surface of the upper housing. The mounting grooves include a turntable groove, an upper swing arm groove, and a lower swing arm groove. The upper swing arm groove and the lower swing arm groove are respectively connected to the turntable groove. The upper swing arm push rod is installed in the upper swing arm groove, the turntable component is installed in the turntable groove, and the lower swing arm push rod and the push connection assembly are linearly connected and installed in the lower swing arm groove.

[0017] Furthermore, the housing includes a lower housing, on the inner surface of which a receiving groove is formed. The receiving groove includes a central groove section and end groove sections located at both ends of the central groove section. The motor is installed in the central groove section, and the gear post and the positioning gear are installed in the end groove sections. A through hole communicating with the housing cavity is opened in the center of the turntable groove, and the transmission post passes through the through hole and is installed in the center of the positioning gear.

[0018] Furthermore, vertical sliding grooves are provided on the groove wall of the swing groove, and insert rods extend laterally on both sides of the lower rod section, which can be inserted into the vertical sliding grooves in a lifting and lowering manner.

[0019] Furthermore, the bottom of the spherical part has a shaft insertion hole, the upper end of the lower rod section is slidably inserted into the insertion hole, and the other end is hinged in the swing groove.

[0020] Furthermore, the bottom end of the lower rod section is hinged to the swing joint groove or the upper swing arm push rod by a pin.

[0021] The beneficial effects of the present invention are as follows: The massager provided by the present invention has an eccentric drive wheel that simultaneously drives the upper massage arm structure and the lower massage arm structure, which simplifies the structure and makes the entire massager compact. At the same time, the upper massage arm structure adopts a ball-head swing rod with a spherical part as the swing fulcrum. The ball-head guide seat restricts the rise and fall of the spherical part, ensuring stable massage operation. Furthermore, one end of the ball-head swing rod is driven by the eccentric drive wheel to move in an arc, so that the massage wheel has an arc displacement trajectory during massage, which can improve the massage trajectory of the massage wheel, realize multi-part massage in the massage space, and improve massage comfort.

Detailed Implementation

[0034] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0035] like Figure 1 , Figure 2As shown, the present invention provides a massager, including a housing 10, a drive module 20 installed in the housing 10, and massage structures (not shown) connected to the two ends of the drive module 20 respectively.

[0036] Each end of the massage structure includes an upper arm structure 30, an upper massage head 301 connected to the upper arm structure 30, a lower arm structure 40, and a lower massage head 401 connected to the lower arm structure 40.

[0037] The drive module 20 is installed inside the housing 10 and includes a motor 21 and turntable components 22 installed at both ends of the motor 21. The upper swing arm structure 30 and the lower swing arm structure 40 of each massage structure are installed at one end of the housing 10 and connected to the turntable component 22 at the corresponding end of the drive module 20. The motor 21 drives the turntable components 22 at both ends to rotate simultaneously. The turntable components 22 correspondingly drive the upper swing arm structure 30 and the lower swing arm structure 40 at each end to move simultaneously, so that the massage head ends of the upper swing arm structure 30 and the lower swing arm structure 40 move accordingly, realizing the massage action of the massage structure.

[0038] In this embodiment, the upper massage head 301 is provided with two massage rollers, which are set at approximately right angles and are suitable for pressing the shoulders and neck, while the lower massage head 401 is provided with one massage roller and is suitable for pressing the back.

[0039] The turntable component 22 includes a disc body 221 and a connecting body 222 eccentrically disposed on the disc surface of the disc body 221. The disc body 221 rotates around its axis, causing the connecting body 222 to rotate integrally around the axis of the disc body 221. In this embodiment, the connecting body 222 is cylindrical.

[0040] Please see Figure 3 , Figure 4 The upper swing arm structure 30 includes an upper swing arm push rod 31, a ball head swing rod 32, and a ball head guide seat 33. One end of the upper swing arm push rod 31 is provided with a sleeve hole 311 for rotatably sleeved on the connecting body 222, and the other end is formed with a swing groove 312 for receiving one end of the ball head swing rod 32.

[0041] Furthermore, a clamping wall 3121 is formed in the swing groove 312, so that the ball head swing rod 32 can only swing along the clamping wall 3121, and cannot rotate around its axis in the swing groove 312.

[0042] The ball-head swing arm 32 includes a spherical portion 321, an upper rod section 322 formed at the upper end of the spherical portion 321, and a lower rod section 323 formed at the lower end of the spherical portion 321. The spherical portion 321 serves as the swing fulcrum of the ball-head swing arm 32, that is, both the upper rod section 322 and the lower rod section 323 swing with the spherical portion 321 as the fulcrum. The spherical portion 321 is rotatably housed in the ball-head guide seat 33, and its lifting and lowering are restricted by the ball-head guide seat 33. The upper rod section 322 extends upward through the ball-head guide seat 33 and connects to the upper massage head 301, and the lower rod section 323 extends downward through the ball-head guide seat 33 and is housed in the swing groove 312.

[0043] Furthermore, a horizontal column is formed at the end of the lower rod section 323, and abutting end faces 3231 are formed at both ends of the horizontal column to cooperate with the clamping wall surface 3121. In this way, the lower rod section 323 is inserted into the swing groove 312 and can only swing but cannot rotate around its axis.

[0044] Understandably, when the lower rod segment 323 swings, since the spherical part 321 serves as a fixed pivot point, the end of the lower rod segment 323 will have a certain range of vertical sliding relative to the swing groove 312. The swing groove 312 has a sufficient depth for the end of the lower rod segment 323 to slide, so it will not interfere with the swing of the lower rod segment 323.

[0045] The ball head guide seat 33 is fixedly mounted on the housing 10 to accommodate the spherical part 321 and limit its movement, allowing the spherical part 321 to rotate within it. In this embodiment, the ball head guide seat 33 includes an upper spherical shell seat 331 and a lower spherical shell seat 332. The upper spherical shell seat 331 has an upper hemispherical shell 3311 protruding from it, and the lower spherical shell seat 332 has a lower hemispherical shell 3321 recessed therefrom. The upper spherical shell seat 331 and the lower spherical shell seat 332 cooperate to form a spherical groove for accommodating the spherical part 321. The upper hemispherical shell 3311 has an upper through hole 3312 for the upper rod section 322 to pass through, and the lower spherical shell seat 332 has a lower through hole 3322 for the lower rod section 323 to pass through. During installation, after the spherical part 321 is installed in the spherical groove, the lower spherical housing seat 332 is locked onto the upper spherical housing seat 331, and then the upper spherical housing seat 331 is locked onto the housing 10.

[0046] See also Figure 5 When the upper swing arm structure 30 moves, one end of the upper swing arm push rod 31 follows the connecting body 222 of the turntable 21 to make a circular motion, and the other end of the upper swing arm push rod 31 makes a corresponding arc reciprocating motion on the plane, which drives the lower rod section 323 of the ball head swing rod 32 to swing around the spherical part 321. Corresponding to the movement of the upper rod section 322 of the ball head swing rod 32, it drives the upper massage head 301 to massage, and the upper massage head moves in a corresponding arc massage trajectory.

[0047] Please see Figure 6 The lower arm structure 40 includes a lower arm push rod 41, a push connecting assembly 42, and a swing arm 43. One end of the lower arm push rod 41 is sleeved on the connecting body 222 and the other end is rotatably connected to the push connecting assembly 42. One end of the swing arm 43 is hinged to the housing 10 and the other end is rotatably connected to one end of the push connecting assembly 42. The swing arm 43 is equipped with a lower massage head 401.

[0048] The horizontal push connection assembly 42 can adopt a universal coupling structure. In this embodiment, the horizontal push connection assembly 42 includes a horizontal swing connector 421 and a vertical swing connector 422. One end of the horizontal swing connector 421 is equipped with a longitudinal pin parallel to the connecting body 222, and the other end is equipped with a transverse pin perpendicular to the longitudinal pin. The lower swing arm push rod 41 is hinged to the horizontal swing connector 421 through the longitudinal pin. One end of the vertical swing connector 422 is hinged to the horizontal swing connector 421 through the transverse pin, and the other end of the vertical swing connector 422 is hinged to the swing arm 43 through another transverse pin, thereby realizing the free angle steering connection between the lower swing arm push rod 41 and the swing arm 43.

[0049] When the lower swing arm structure 40 moves, one end of the lower swing arm push rod 41 follows the connecting body 222 of the turntable 21 to make a circular motion, and the other end of the lower swing arm push rod 41 makes a corresponding arc reciprocating motion on the plane, driving the push connecting assembly 42 to move. Through the switching of the degree of freedom of the push connecting assembly 42 and the limiting of the push connecting assembly 42 by the sliding groove on the housing 10, the push connecting assembly 42 pushes and pulls the swing arm 43 back and forth, thereby swinging repeatedly around the hinge of the housing 10 of the swing arm 43, driving the lower massage head 401 to make a reciprocating linear motion.

[0050] In summary, the massager provided by this invention simplifies the structure and improves synchronization by fitting the upper arm push rod 31 of the upper arm structure 30 and the lower arm push rod 41 of the lower arm structure 40 onto the connecting body 222 of the same turntable component 22. The rotation of the turntable component 22 simultaneously drives the upper arm structure 30 and the lower arm structure 40. Furthermore, the upper arm structure 30 employs a structure where the spherical portion 321 at the center of the ball-head swing rod 32 is matched with a ball-head guide seat 33 for positioning. The two ends of the ball-head swing rod 32 use the spherical portion 321 at the central connection as the pivot point, and the ball-head guide seat 33 restricts the rise and fall of the spherical portion 321, ensuring the stability of the running trajectory of the upper rod section 322 and correspondingly improving the stability of the massage.

[0051] Further, please refer to Figure 2 , Figure 3 , Figure 7 The drive module 20 includes a transmission component 23, and the motor 21 drives the turntable 22 to rotate through the transmission component 23.

[0052] The transmission assembly 23 includes a gear column structure 231, a positioning gear 232, and a transmission column 233. The motor 21 is a dual-shaft worm motor, meaning that the motor body has worms extending to both ends. The gear column structure 231 includes a gear column, a main gear 2311 fixedly mounted on the gear column, and a secondary gear 2312. The main gear 2311 meshes with the worm of the motor 21 at a right angle, and the secondary gear 2312 meshes with the positioning gear 232. Thus, the worm of the motor 21 rotates, driving the positioning gear 232 to rotate. The transmission column 233 is installed at the center of the positioning gear 232. The rotation of the positioning gear 232 correspondingly drives the transmission column 233 to rotate together. A turntable component 22 is installed on the top surface of the transmission column 233. The rotation of the transmission column 233 drives the turntable component 22 to rotate together. Specifically, the disc body 221 can be locked onto the transmission column 233.

[0053] Understandably, the transmission component 23 is set to meet the requirements of the spacing between the two massage structures and the transmission stability; otherwise, the turntable component 22 can be directly driven to rotate by the worm gear of the motor 21.

[0054] Furthermore, in conjunction with reference Figure 2 , Figure 8 The housing 10 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 cooperate to form a shell with a hollow cavity. The drive module 20 is installed in the cavity of the shell. The upper housing 11 has mounting grooves 111 at both ends on its upper surface for mounting the upper swing arm structure 30 and the lower swing arm structure 40. The mounting groove 111 includes a turntable groove 1111, an upper swing arm groove 1112, and a lower swing arm groove 1113. The turntable groove 1111 has a through hole 1114 in the center that communicates with the shell cavity. The upper swing arm groove 1112 and the lower swing arm groove 1113 are respectively connected to the turntable groove 1111. In this embodiment, the upper swing arm groove 1112 and the lower swing arm groove 1113 are approximately perpendicular. The upper swing arm groove 1112 extends towards one end of the upper housing 11 but does not penetrate the end wall of one end of the upper housing 11. The lower swing arm groove 1113 extends towards one side of the upper housing 11 and penetrates the side wall of that side. A plurality of threaded posts 1115 are formed on the upper surface of the upper housing 11 on both sides of the upper swing arm groove 1112.

[0055] See also Figure 9 , Figure 10During installation, the upper swing arm push rod 31 is installed in the upper swing arm groove 1112, the turntable part 22 is installed in the turntable groove 1111, one end of the upper swing arm push rod 31 is sleeved on the connecting body 222 of the disc body 221, and the other end extends into the end of the upper swing arm groove 1112. The ball head guide seat 33 receives the spherical part 321 of the ball head swing rod 32 and the ball head guide seat 33 is fixed to the upper housing 11 by the screw post 1115. The cross post of the lower rod section 323 of the ball head swing rod 32 is inserted into the swing groove 312 of the upper swing arm push rod 31. The lower swing arm structure 40 has a lower swing arm push rod 41, a horizontal swing connector 421 and a vertical swing connector 422 that are linearly connected and installed in the lower swing arm groove 1113 of the upper housing 11. The swing arm 43 has a flat extension section and a downward tilting section connected to one end of the flat extension section. A pin hole is provided at the connection between the flat extension section and the downward tilting section. The swing arm 43 is hinged to the vertical swing connector 422 by the pin. The other end of the flat extension section is fixedly connected to the lower massage wheel 401. The end of the downward tilting section is hinged to the lower housing 12 of the housing 10.

[0056] A receiving groove is formed on the inner surface of the lower housing 12 for mounting the drive module 20. The receiving groove includes a central groove section 121 and end groove sections 122 located at both ends of the central groove section 121, wherein the end groove sections 122 have a first gear mounting area 1221 and a second gear mounting area 1222.

[0057] During installation, the motor 21 is mounted in the central slot section 121, the gear post is mounted in the first gear mounting area 1221, and the positioning gear 232 is mounted in the second gear mounting area 1222. The positioning gear 232 meshes with the secondary gear 2312. The transmission post 233 passes through the through hole 1114 and is mounted in the center of the positioning gear 232. The turntable component 22 is mounted on the top of the transmission post 233. The rotation of the output shafts at both ends of the motor 21 around the horizontal axis drives the positioning gear 232 to rotate around the vertical axis, which in turn drives the transmission post 233 and the turntable component 22 to rotate.

[0058] Understandably, another way to connect the ball joint sway bar 32 and the upper swing arm push rod 31 is to have vertical sliding grooves opened on the groove wall of the swing connection groove 312, and insert rods extending laterally on both sides of the lower rod section 323. The insert rods can be inserted into the vertical sliding grooves in a lifting and lowering manner, so that the lower rod section and the upper swing arm push rod 31 can be swung and connected, which ensures that the lower rod section 323 has space for sliding and can also be swung.

[0059] In another configuration, the ball joint swivel 32 and the upper swing arm push rod 31 are connected in a manner where a pin hole is formed at the bottom of the spherical portion 321. The upper end of the lower rod section 323 is slidably inserted into the pin hole, and the other end is hinged to the swing groove 312. Thus, the ball joint swivel 32 and the upper swing arm push rod 31 are rotatably connected. The raising and lowering of the lower rod section 323 is the raising and lowering of its top end within the pin hole. The bottom end of the lower rod section 323 can be hinged to the swing groove 312 or the upper swing arm push rod 31 via a pin.

[0060] Any combination of various embodiments of the present invention, provided it does not violate the inventive concept of the present invention, shall be regarded as the content disclosed by the present invention; within the scope of the technical concept of the present invention, any simple modifications to the technical solution and any combination of different embodiments that do not violate the inventive concept of the present invention shall be within the protection scope of the present invention.
