Description

Technical Field

[0001] This invention relates to the field of physiotherapy device technology, and in particular to a portable pillow kneading swing arm mechanism. Prior Technology

[0002] In modern society, due to prolonged desk work, use of electronic devices, and poor sleeping posture, more and more people are experiencing health problems such as neck and shoulder fatigue, muscle stiffness, and even cervical spondylosis. To relieve these discomforts, people often use massage pillows to massage their bodies.

[0003] Existing massage pillows mostly use rotation, rolling, or vibration for massage. The massage methods are simple and fixed, which do not easily meet users' needs for massage intensity and methods. In addition, when the massage pillow is not in use, the protruding massage head can put extra pressure on the neck, which can easily cause discomfort to users when sleeping due to the resistance of the massage head. Furthermore, the structure of these massage pillows is usually not removable, which means that with long-term use, some dead corners can accumulate sweat and dust, affecting the lifespan of the device and hygiene. Summary of the Invention

[0027] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] As shown in Figures 1 to 11, an embodiment of the present invention provides a portable pillow kneading and swinging arm mechanism, including a mechanism base 101, a neck massage head 102, a shoulder massage head 103, and a trapezius muscle massage head 104, and further includes:

[0029] Two neck massage heads 102 are provided, both of which are tilted, with the included angle of the two neck massage heads 102 opening upwards;

[0030] There are two shoulder massage heads 103 and two trapezius muscle massage heads 104. Both shoulder massage heads 103 and trapezius muscle massage heads 104 are horizontally positioned, with the two shoulder massage heads 103 located on the outer sides of the two neck massage heads 102, and the trapezius muscle massage heads 104 located below the corresponding shoulder massage heads 103.

[0031] The transmission unit, located above the base 101 of the movement mechanism, is used to drive the neck massage head 102, shoulder massage head 103 and trapezius muscle massage head 104 to perform kneading movements;

[0032] The transmission unit is equipped with a reversing component 301, which is used to adjust the kneading action of the neck massage head 102 and the shoulder massage head 103 to increase the variety of kneading actions;

[0033] When the user does not need to knead, the two neck massage heads 102 support the user's neck, while the shoulder massage head 103 and trapezius muscle massage head 104 do not come into contact with the user's neck and shoulders to reduce the resistance of the massage heads to the user.

[0034] In this embodiment of the invention, before use, the device's base 101 is fixedly connected to a pre-set recess on the surface of the sponge pillow block 801, facilitating the installation of the neck massage head 102, shoulder massage head 103, and trapezius muscle massage head 104. In the off state, the neck massage head 102 is positioned at its lowest relative to the base 101. When the user lies on the sponge pillow block 801, the two neck massage heads 102 support the neck, while the shoulder massage head 103 and trapezius muscle massage head 104 are located below the neck, not in contact with it. This ensures that the sponge pillow block 801 and the entire device fit and support the user's neck well, thus reducing the likelihood of significant discomfort when the user sleeps on the sponge pillow block 801 and the entire device for an extended period.

[0035] When kneading and massaging are needed, the neck massage head 102, shoulder massage head 103, and trapezius muscle massage head 104 are used to massage the user's neck, shoulders, and trapezius muscles.

[0036] The combined use of the transmission unit and the reversing component 301 allows for a variety of massage techniques.

[0037] The upper surface of the mechanism base 101 is fixedly connected to the mechanism protective shell 201. Two first swing arms 210 are arranged above the mechanism protective shell 201. Neck massage head 102 is fixedly connected to the surface of the first swing arm 210. Shoulder massage heads 103 are respectively arranged at the ends of the corresponding first swing arms 210. A universal ball frame 209 is fixedly connected to the bottom of the first swing arm 210. A ball groove 211 is opened on the surface of the mechanism protective shell 201. A constraint line groove 212 is symmetrically opened on the inner wall of the ball groove 211. A constraint protrusion 213 is symmetrically fixedly connected to the surface of the universal ball frame 209. The spherical part of the universal ball frame 209 is located inside the ball groove 211. The constraint protrusions 213 are respectively located inside the corresponding constraint line grooves 212. The reversing member 301 is arranged below the two universal ball frames 209.

[0038] A battery compartment 202 is mounted on the surface of the mechanism protective shell 201. A brushless motor 203 is installed inside the mechanism protective shell 201. A helical gear 204 is fixedly connected to the end of the output shaft of the brushless motor 203. A first rotating shaft 205 is symmetrically arranged inside the mechanism protective shell 201. The first rotating shaft 205 is rotatably connected to the mechanism protective shell 201 through a first circular groove symmetrically opened on the inner wall of the mechanism protective shell 201. A helical gear 206 and a second gear 207 are fixedly connected from top to bottom on the surface of the first rotating shaft 205. Both helical gears 206 are meshed with the helical gear 204. A third gear 208 is symmetrically arranged inside the mechanism protective shell 201. The third gears 208 are meshed with the corresponding second gears 207. A reversing component 301 is disposed on the surface of the two third gears 208.

[0039] The inner bottom surface of the movement protective case 201 is symmetrically provided with a first circular groove 214, and the third gear 208 is rotatably connected to the inside of the first circular groove 214 through an annular protrusion on the bottom surface;

[0040] The reversing component 301 includes a first reversing block 3011 and a second reversing block 3012. The first reversing block 3011 and the second reversing block 3012 are respectively disposed on the surfaces of the two third gears 208. The inclined surfaces of the first reversing block 3011 and the second reversing block 3012 are each provided with a first cylindrical portion. The first cylindrical portion is inserted into a first columnar groove opened on the bottom surface of the corresponding universal ball frame 209.

[0041] The second reversing block 3012 is fixedly connected to the upper surface of the corresponding third gear 208. The first reversing block 3011 is inserted into the second columnar groove opened on the surface of the corresponding third gear 208 through the second cylindrical part protruding from the bottom surface. The inner bottom surface of the first reversing block 3011 is provided with an adjustment groove 3013, which is not completely annular. An adjustment top block 3014 is provided inside the adjustment groove 3013, and the adjustment top block 3014 is fixedly connected to the corresponding third gear 208.

[0042] In this embodiment of the invention, under the constraint of the surface constraint protrusions 213 and constraint grooves 212, the universal ball frame 209 can perform multi-angle movements inside the ball socket groove 211 by the compression of the inclined surfaces of the first reversing block 3011 and the second reversing block 3012 on the bottom surfaces of the two universal ball frames 209. The specific adjustment of the kneading action of the neck massage head 102, shoulder massage head 103 and trapezius muscle massage head 104 by the reversing component 301 is as follows: when the brushless motor 203 is running, the helical gear 204 rotates in one direction. The rotation of the helical gear 204 drives the two third gears 208 through the transmission of the second gear 207, the helical gear 206 and the first rotating shaft 205. When rotation occurs, the rotation of the third gear 208 causes the second reversing block 3012 to rotate accordingly. Through the first cylindrical part on the inclined surface of the second reversing block 3012 and the universal ball frame 209, the corresponding first swing arm 210 swings. The third gear 208, which is in contact with the first reversing block 3011, abuts against a side wall of the adjusting groove 3013 through the adjusting top block 3014, thereby causing the first reversing block 3011 to rotate synchronously, and in turn causing the corresponding first swing arm 210 to swing.

[0043] When the operation of the brushless motor 203 causes the helical rack 204 to rotate in the opposite direction, the third gear 208, which is in contact with the first reversing block 3011, drives the adjusting top block 3014 to rotate along the curved inner wall of the adjusting groove 3013 until it abuts against the other side wall of the adjusting groove 3013. Then, the first reversing block 3011 and the third gear 208 rotate synchronously, thereby driving the corresponding first swing arm 210 to swing.

[0044] When the adjusting top block 3014 abuts against one of the side walls of the adjusting groove 3013, the first reversing block 3011 and the second reversing block 3012 are symmetrically arranged inside the movement protective shell 201. The rotation of the helical gear 204 causes the adjusting top block 3014 to continue to abut against the side wall, and the movements of the two first swing arms 210 are synchronized.

[0045] When the rotation of the helical gear 204 causes the adjusting top block 3014 to move to another side wall inside the adjusting groove 3013, the movements of the two first swing arms 210 cannot be synchronized. The two first swing arms 210 move asynchronously, which is called asynchronous movement.

[0046] During the swing of the first swing arm 210, since the two shoulder massage heads 103 are located on the outside of the two neck massage heads 102, the shoulder massage heads 103 will not interfere with the neck when massaging the user's shoulders, so that the user does not need to massage and knead to close the shoulder massage heads 103.

[0047] An eccentric block 401 is fixedly connected to the annular protrusion on the bottom surface of the third gear 208. An eccentric bracket 402 is rotatably connected to the shaft on the bottom surface of the eccentric block 401 through the first bearing. A hinge seat 405 is symmetrically fixedly connected to the surface of the mechanism protective shell 201. The surface of the hinge seat 405 is U-shaped away from the mechanism protective shell 201. A second swing arm 403 is hinged in the U-shaped part of the hinge seat 405. A constraint groove 406 is opened on the surface of the hinge seat 405. A constraint slider 408 is slidably connected inside the constraint groove 406. The bottom end of the constraint slider 408 is fixedly connected to the surface of the eccentric bracket 402. A guide ball head rod 410 is fixedly connected to the surface of the second swing arm 403. A guide groove 409 is opened on the surface of the eccentric bracket 402. The ball end of the guide ball head rod 410 is slidably connected inside the guide groove 409. The trapezius muscle massage head 104 is set at the end of the second swing arm 403.

[0048] In this embodiment of the invention, when the third gear 208 rotates, it drives the eccentric block 401 to rotate synchronously. The shaft of the eccentric block 401 is eccentrically set, so when the eccentric block 401 rotates, it will drive the eccentric bracket 402 to move. Since the eccentric bracket 402 is fixedly connected to the constraint slider 408, and the constraint slider 408 is constrained by the constraint groove 406, the eccentric bracket 402 will make linear reciprocating motion along the extension direction of the constraint groove 406 when the eccentric block 401 rotates. The second swing arm 403, which is hinged to the mechanism protective shell 201 through the hinge seat 405, rotates around the hinge seat 405 during the reciprocating motion of the eccentric bracket 402 through the squeezing action of the guide groove 409 on the guide ball head rod 410, thereby massaging the user's trapezius muscle through the trapezius muscle massage head 104.

[0049] When the user does not need to use the massage function, the eccentric bracket 402 is moved to the position furthest from the corresponding hinge seat 405, so that the eccentric bracket 402 moves the second swing arm 403 to a horizontal state through the guide groove 409 and the guide ball head rod 410, so that the second swing arm 403 and the trapezius muscle massage head 104 are converged below the user's neck and do not come into contact with the user's neck, thereby reducing the user's resistance to the pillow device when sleeping for a long time.

[0050] A Hall sensor 501 is mounted on the surface of the mechanism protective shell 201. A sensing magnetic column 502 is embedded on the surface of the third gear 208 near the Hall sensor 501. A PCB control box 503 is fixedly connected to the surface of the mechanism protective shell 201. A controller 504 is provided on one side of the mechanism protective shell 201. A heating lamp plate 505 is provided on the top of the mechanism protective shell 201.

[0051] In this embodiment of the invention, the Hall sensor 501 senses the sensing magnetic column 502, so that the positions of the neck massage head 102, shoulder massage head 103, and trapezius muscle massage head 104 can be identified and recorded by the PCB control box 503, and the controller 504 controls the operation of the device. The heating lamp plate 505 is installed above the core protective shell 201. Specifically, the sponge pillow block 801 covers the area of ​​the core protective shell 201 that does not interfere with the movement of the first swing arm 210, neck massage head 102, shoulder massage head 103, trapezius muscle massage head 104, eccentric bracket 402, and second swing arm 403. The heating lamp plate 505 is fixed on the surface of this part of the sponge pillow block 801 near the user's neck to heat the user's neck, shoulders, and trapezius muscles, thereby providing a heat therapy effect. The surface of the heating lamp plate 505 is provided with a heat insulation layer to prevent high temperature from burning the user's skin.

[0052] It should be noted that the use of brushless motor 203, Hall sensor 501, sensing magnetic column 502, PCB control box 503, controller 504 and heating lamp board 505 requires power from battery compartment 202. The wiring connection method, working principle and usage process of battery compartment 202, brushless motor 203, Hall sensor 501, sensing magnetic column 502, PCB control box 503, controller 504 and heating lamp board 505 are known in the prior art and will not be described in detail here.

[0053] A cloth cover 603 is provided above each ball groove 211. The cloth cover 603 is elastic to adapt to the kneading action of the first swing arm 210 and undergo elastic deformation. The first swing arm 210, the neck massage head 102 and the shoulder massage head 103 are all located inside the corresponding cloth cover 603. A number of massage protrusions 604 are uniformly fixedly connected to the surface of the cloth cover 603. The massage protrusions 604 are uniformly distributed on the surface of the cloth cover 603, and the massage protrusions 604 are distributed along the cloth surface with a gradually increasing volume trend.

[0054] The surface of the movement protective shell 201 is symmetrically fixedly connected with several constraint buckles 601 on both sides of the ball socket groove 211. An elastic support strip 602 is provided above the ball socket groove 211. The elastic support strip 602 is slidably connected to the corresponding elastic support strip 602 through the T-shaped constraint groove opened on the surface of the constraint buckle 601. The cloth cover 603 is fixedly connected to the upper surface of the elastic support strip 602.

[0055] When the first swing arm 210 drives the neck massage head 102 to perform a kneading action, the massage protrusions 604 provide auxiliary pressure to the neck. By adjusting the positional relationship between the elastic support bar 602 and the restraint buckle 601, the user can make the neck not contact the massage protrusions 604 or contact the massage protrusions 604 of the required size as needed.

[0056] Several fixing strips 605 are evenly fixedly connected to the inner wall of the cover 603 at a position away from the elastic support strip 602. The fixing strips 605 are used to fix the end of the cover 603 away from the elastic support strip 602 to the side away from the movement protective shell 201.

[0057] In this embodiment of the invention, when a user sleeps on the device for an extended period, the cloth cover 603 prevents the skin of the neck from contacting the first swing arm 210, the shoulder massage head 103, and the neck massage head 102. This prevents sweat and dust from remaining on the surfaces of the first swing arm 210, the neck massage head 102, and the shoulder massage head 103, while also preventing dust from entering the ball socket groove 211. Simultaneously, the user can move the elastic support strip 602 within the corresponding constraint buckle 601 according to their needs, allowing the massage protrusions 604 of a certain size on the surface of the cloth cover 603 to contact the neck skin. During the swing of the first swing arm 210, the massage protrusions 604 provide auxiliary massage to the neck. When the auxiliary massage of the massage protrusions 604 is not needed, the cloth cover 603 can be rotated to an area without massage protrusions 604, allowing the cloth surface of the cloth cover 603 to directly adhere to the user's neck skin.

[0058] When the fabric cover 603 needs to be replaced or cleaned, apply a force away from the elastic support bar 602 to the fabric cover 603 until the elastic support bar 602 leaves the interior of the restraint buckle 601 by elastic deformation. When the fabric cover 603 needs to be installed, press the elastic support bar 602 into the T-shaped restraint groove of the restraint buckle 601 by elastic deformation until the elastic support bar 602 is located inside the T-shaped restraint groove.

[0059] The hook side of the fastener is fixed to the side of the fixed cloth strip 605 near the inner wall of the cloth cover 603, and the loop side of the fastener is fixed to the surface of the sponge pillow block 801. By pressing one of the fixed cloth strips 605 inside the cloth cover 603 with the loop side, one end of the cloth cover 603 is fixed to the surface of the sponge pillow block 801, so that the massage protrusions 604 on the surface of the cloth cover 603 or the cloth surface of the cloth cover 603 can be in more even contact with the user's neck skin.

[0060] It should be noted that the spherical part of the universal ball frame 209 is hemispherical, with a flat bottom and a columnar protrusion at the top, which facilitates the universal ball frame 209 to rotate at multiple angles inside the ball socket 211.

[0061] The shoulder massage head 103 is fixedly connected to the first swing arm 210 or rotatably connected to the first swing arm 210 via a second bearing. The trapezius muscle massage head 104 is fixedly connected to the second swing arm 403 or rotatably connected to the second swing arm 403 via a third bearing. Users can choose the appropriate connection method according to their needs.

[0062] The elastic support bar 602 has a T-shaped cross-section, which facilitates its constraint by the constraint buckle 601.

[0063] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
