Detailed implementation manners

[0051] The core of the present utility model is to provide a massage pad that can perform enhanced massage on special parts.

[0052] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for the convenience of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0053] As Figures 1-3As shown in the figure, an embodiment of the present utility model discloses a massage cushion, which includes a massage cushion main body 100, a head movement mechanism assembly 300, a back movement mechanism assembly 200, a first Hall sensor 206 and a magnetic induction assembly.

[0054] Among them, the massage cushion main body 100 has a traveling rack 104 and a traveling guide rail 106. The traveling guide rail 106 provides a guiding function for the movement of the back movement mechanism assembly 200, and the traveling rack 104 is used to cooperate with the back traveling gear 205 of the back movement mechanism assembly 200 to provide the traveling power for the back movement mechanism assembly 200.

[0055] The head movement mechanism assembly 300 is arranged on the massage cushion main body 100. Those skilled in the art can set the head movement mechanism assembly 300 as a movable structure or a fixed structure according to needs. When it is a movable structure, its movement mode is the same as that of the back movement mechanism assembly 200, both moving along the traveling guide rail 106 and relying on the cooperation of the traveling rack 104 and its own head traveling gear 306 to provide traveling power.

[0056] As Figure 4 shown, since the back movement mechanism assembly 200 needs to massage a larger range, it needs to be designed as a movable structure to massage in a larger range. The back movement mechanism assembly 200 includes a back movement mechanism seat 201 that is slidably matched with the traveling guide rail 106, and a back traveling gear 205 that is arranged on the back movement mechanism seat 201 and is matched with the traveling rack 104. By driving the back traveling gear 205 to rotate and through the cooperation of the back traveling gear 205 and the traveling rack 104, the back movement mechanism assembly 200 can move up and down along the traveling rack 104.

[0057] In order to improve the stability of the movement of the back movement mechanism assembly 200, multiple traveling guide rails 106 can be arranged. Each traveling guide rail 106 can be arranged at intervals and has the same track, so as to keep the back movement mechanism assembly 200 moving completely along the curve of the traveling rack 104 inside the backrest cushion 101. In order to fit the back curve of the user and enable the back movement mechanism assembly 200 to move along the back curve, both the traveling rack 104 and the traveling guide rail 106 are curve structures that match the back curve. That is, the extension tracks of the traveling rack 104 and the traveling guide rail 106 should be designed according to the back physiological curve of the human body.

[0058] The lower end of the massage cushion main body 100 has a backrest slide rail block 108, and the lower end of the traveling guide rail 106 abuts against the backrest slide rail block 108.

[0059] One of the first Hall sensor 206 and the magnetic induction assembly is disposed on the back movement base 201, and the other is disposed at a preset position of the massage pad main body 100. In the preset mode, when the first Hall sensor 206 senses the magnetic induction assembly, the back movement assembly 200 stops walking. It should be noted that through the selection of the mode, the massage pad can be controlled in the local enhanced massage mode and the wandering massage mode.

[0060] In the local enhanced massage mode, when the first Hall sensor 206 senses the magnetic induction assembly, the back movement assembly 200 stops walking to perform enhanced massage on this part. It should be noted that in this mode, the back movement assembly 200 can stay at this part for continuous massage, or stay at this position for a preset time (i.e., continuous massage for a preset time), and then continue to walk.

[0061] In the wandering massage mode, even if the first Hall sensor 206 senses the magnetic induction assembly, the back movement assembly 200 will not stop, but maintain the continuous wandering massage mode. For the switching between the two modes, the user can select by himself / herself. For example, a corresponding mode switching switch can be set to switch between the local enhanced massage mode and the wandering massage mode through the mode switching switch.

[0062] For the massage pad provided by the present utility model, a magnetic induction assembly is disposed on one of the massage pad main body 100 and the back movement base 201, and the first Hall sensor 206 is disposed on the other. The first Hall sensor 206 can sense the magnetic field of the magnetic induction assembly. The first Hall sensor 206 can be disposed on the back movement base 201, and the magnetic induction assembly is disposed at a preset position of the massage pad main body 100. In the preset mode, when the first Hall sensor 206 senses the magnetic induction assembly, the back movement assembly 200 stops walking, so that the back movement assembly 200 can be stopped at a preset position of the massage pad main body 100. For example, if the preset position is set at the part where the user needs key massage, then key massage can be performed on this part.

[0063] As Figure 2 shown, there are usually two areas that need key massage in the back area, namely the upper back and the waist, and these two areas have relatively rich acupoints. Therefore, magnetic sensors are disposed in both of these two areas. Based on this, in this embodiment, the magnetic induction assembly includes a first magnetic sensor 102 and a second magnetic sensor 103. The first magnetic sensor 102 is disposed in the back area of the massage pad main body 100, and the second magnetic sensor 103 is disposed in the waist area of the massage pad main body 100. The first Hall sensor 206 is disposed on the back movement base 201.

[0064] In the preset mode, when the back movement assembly 200 moves to the position where the first Hall sensor 206 senses the first magnetic induction element 102, the back movement assembly 200 stops walking. It should be noted that, similar to the above embodiments, through the selection of modes, the massage mat can be controlled in the local enhanced massage mode and the wandering massage mode.

[0065] The first magnetic induction element 102 is arranged in the back area, which can focus on enhancing the massage of the back, mainly massaging acupoints such as Xinshu acupoint, Dushu acupoint, Geshu acupoint, Yishu acupoint, Ganshu acupoint, and Danshu acupoint. Through enhanced massage, it is mainly used to regulate the user's respiratory discomfort, chest tightness, palpitations, asthma, hypertension, heart and lung diseases, respiratory tract infections, etc.

[0066] In the preset mode, when the back movement assembly 200 moves to the position where the first Hall sensor 206 senses the second magnetic induction element 103, the back movement assembly 200 stops walking. It should be noted that, similar to the above embodiments, through the selection of modes, the massage mat can be controlled in the local enhanced massage mode and the wandering massage mode.

[0067] The second magnetic induction element 103 is arranged in the waist area, which can focus on enhancing the massage of the waist, mainly massaging acupoints such as Danshu acupoint, Pishu acupoint, Weishu acupoint, and Shenshu acupoint. After enhanced massage, it mainly regulates disharmony between the spleen and stomach, stagnation of liver qi, gastric distension, gastric acid, bad breath, cold limbs, anemia, stomachache, etc. At the same time, it can also regulate the user's low back pain, diarrhea, constipation, malabsorption, diseases of the uterus, kidneys, bladder, etc.

[0068] It should be noted that for other parts that need to be massaged intensively, the way of setting magnetic induction elements can also be adopted for intensive massage.

[0069] Such as Figure 2 and Figure 5 As shown, the first magnetic induction element 102 and the second magnetic induction element 103 are installed on the side of the massage mat main body 100 facing away from the back movement assembly 200. In order to ensure that when the first magnetic induction element 102 and the second magnetic induction element 103 are installed on the back of the massage mat main body 100, they can still be sensed by the first Hall sensor 206. In this embodiment, the massage mat main body 100 is respectively provided with a first through hole 109 and a second through hole 110 at the positions of the first magnetic induction element 102 and the second magnetic induction element 103, and the sensing parts of the first magnetic induction element 102 are embedded in the first through hole 109, and the sensing parts of the second magnetic induction element 103 are embedded in the second through hole 110, so that the first Hall sensor 206 can sense the first magnetic induction element 102 through the first through hole 109 and can sense the second magnetic induction element 103 through the second through hole 110.

[0070] Such as Figure 3 and Figure 4As shown, in this embodiment, the head movement assembly 300 includes a head movement walking device and a head movement massage device 309 disposed on the head movement walking device. The head movement walking device is slidably engaged with the walking guide rail 106, and the head movement walking device has a head walking gear 306 that cooperates with the walking rack 104.

[0071] Specifically, the head movement walking device includes a head movement base 301 and a head movement motor 304, a head massage drive gear 305, a head transmission gear 308, and a head walking gear 306 disposed within the head movement base 301. Among them, the head massage drive gear 305 and the head transmission gear 308 can be coaxially arranged. The head movement motor 304 cooperates with the head massage drive gear 305 to drive the head massage drive gear 305 and the head transmission gear 308 to rotate. The head transmission gear 308 meshes with the head walking gear 306, thereby driving the head walking gear 306 to rotate, and finally realizing the walking of the head movement assembly 300.

[0072] The head movement base 301 may include a head movement lower cover and a head movement upper cover. After the head movement lower cover and the head movement upper cover are buckled together, a space for accommodating the head movement motor 304, the head massage drive gear 305, the head transmission gear 308, and the head walking gear 306 can be formed.

[0073] Fixing posts 302 are disposed on the outer side of the head movement base 301. The head movement massage device 309 can be fixed on each fixing post 302 through fasteners. The specific structure of the head movement massage device 309 can be the same as that in the prior art and will not be elaborated herein. A guard plate 3011 is disposed on one side of the head movement base 301 close to the walking rack 104. There are two guard plates 3011 arranged in parallel, and the two guard plates 3011 are respectively located on the upper and lower sides of the walking rack 104 so that the head walking gear 306 can maintain cooperation with the walking rack 104.

[0074] As Figure 4 shown, in a specific embodiment of the present utility model, the massage pad may further include a third magnetic induction member 307 and a second Hall induction member 207. One of the third magnetic induction member 307 and the second Hall induction member 207 is disposed on the head movement walking device, and the other is disposed on the back movement base 201. When the second Hall induction member 207 senses the third magnetic induction member 307, the back movement assembly 200 stops walking. When the back movement assembly 200 moves upward, when the second Hall induction member 207 senses the third magnetic induction member 307, the back movement assembly 200 stops walking to prevent collision with the head movement assembly 300.

[0075] In order to further prevent the back movement assembly 200 from colliding with the head movement assembly 300, a stopper 107 is provided on the travel guide rail 106, and the stopper 107 is used to limit the lower limit position of the head movement assembly 300, and limit the upper limit position of the back movement assembly 200. When the head movement assembly 300 slides downward to collide with the stopper 107, it is restricted by the stopper 107 and cannot continue to move downward; correspondingly, when the back movement assembly 200 moves upward to collide with the stopper 107, it is restricted by the stopper 107 and cannot continue to move upward. Through structural design, when both the head movement assembly 300 and the back movement assembly 200 move to collide with the stopper 107, the head movement assembly 300 and the back movement assembly 200 cannot collide, and the back movement assembly 200 can be prevented from colliding with the head movement assembly 300 by using the hard limit of the stopper 107.

[0076] like Figure 4 and Figure 5 As shown, in a specific embodiment of the present invention, the back movement assembly 200 includes a back movement drive motor 202, a back massage gear 204 and a back travel gear 205.

[0077] The back movement drive motor 202 is arranged on the back movement seat 201, and the back movement seat 201 can be formed by buckling the back movement lower cover and the back movement upper cover 209, and the back movement drive motor 202, the back massage gear 204 and the back running gear 205 are arranged in the space between the back movement lower cover and the back movement upper cover 209. The back massage wheel 208 for massaging the user is arranged on the outside of the back movement upper cover 209.

[0078] There are two back massage gears 204, and both are directly or indirectly connected to the back movement drive motor 202. In this embodiment, the two back massage gears 204 can be arranged on both sides of the back movement drive motor 202, and are connected to the back movement drive motor 202 through the back transmission gears 214. The back massage gears 204 are used to drive the back massage wheel 208 of the back movement assembly 200 to rotate.

[0079] The back walking gear 205 is transmission connected to the back massage gear 204 near the walking rack 104, and the back walking gear 205 can slide axially between a first position and a second position. When the back walking gear 205 is in the first position, it is meshed with the walking rack 104, and when the back walking gear 205 is in the second position, it is disengaged from the walking rack 104.

[0080] In this embodiment, the power source of the back walking gear 205 also comes from the back movement driving motor 202. That is, in this embodiment, both the walking power and the massage power of the back movement assembly 200 come from the back movement driving motor 202. By designing the back walking gear 205 to be movable, its movement between the first position and the second position can be controlled according to requirements to control whether it meshes with the walking rack 104. When meshing with the walking rack 104, the walking function can be realized; when disengaging from the walking rack 104, the enhanced massage function for special positions can be realized.

[0081] As Figure 5 and Figures 8-10 shown, in a specific embodiment of the present utility model, the back walking gear 205 and the back massage gear 204 close to the walking rack 104 are coaxially arranged. Through the coaxial arrangement, the back massage gear 204 transmits power to the back walking gear 205, so that the back massage gear 204 and the back walking gear 205 rotate synchronously.

[0082] A first magnetic attraction member 211 is provided on the back walking gear 205, and a second magnetic attraction member 212 is provided on the back movement base 201. When the second magnetic attraction member 212 is electrified, the second magnetic attraction member 212 adsorbs the first magnetic attraction member 211. Thus, under the action of the magnetic attraction force, the first magnetic attraction member 211 and the back walking gear 205 are moved in the direction of the second magnetic attraction member 212 until the back walking gear 205 is in the second position.

[0083] A bearing 213 is provided on the back movement base 201. One of the inner ring and the outer ring of the bearing 213 is installed on the back movement base 201, and a reset elastic member 210 is provided on the other. When the second magnetic attraction member 212 is powered off, the reset elastic member 210 pushes the back walking gear 205 to the first position. It should be noted that the bearing 213 can be a plain bearing. One support ring of the plain bearing supports on the back movement base 201, and a reset elastic member 210 is provided on the other support ring. One end of the reset elastic member 210 abuts against the back walking gear 205. Under the elastic force of the reset elastic member 210, the back walking gear 205 can be pushed to the first position. Under the action of the bearing 213, the back walking gear 205 can drive the reset elastic member 210 to rotate together, thus avoiding friction between the reset elastic member 210 and the back walking gear 205.

[0084] When the second magnetic attraction member 212 is electrified, the second magnetic attraction member 212 adsorbs the first magnetic attraction member 211. Thus, under the action of the magnetic attraction force, overcoming the elastic force of the reset elastic member 210, the first magnetic attraction member 211 and the back walking gear 205 are attracted in the direction of the second magnetic attraction member 212, and the reset elastic member 210 is deformed and stores energy until the back walking gear 205 is in the second position.

[0085] When the second magnetic attraction member 212 is powered off, the second magnetic attraction member 212 loses the magnetic attraction force on the first magnetic attraction member 211. Thus, under the elastic force of the reset elastic member 210, the reset elastic member 210 resets and pushes the back walking gear 205 in a direction away from the second magnetic attraction member 212 until the back walking gear 205 is in the first position.

[0086] In this embodiment, there are two second magnetic attraction members 212, which are respectively arranged corresponding to the first magnetic induction member 102 and the second magnetic induction member 103, such that when the first Hall induction member 206 senses the first magnetic induction member 102, one of the second magnetic attraction members 212 can attract the first magnetic attraction member 211; when the first Hall induction member 206 senses the second magnetic induction member 103, the other second magnetic attraction member 212 can attract the first magnetic attraction member 211.

[0087] As Figure 5 shown, in this embodiment, a third through hole 112 and a fourth through hole 113 are respectively formed beside the positions corresponding to the first through hole 109 and the second through hole 110, and second magnetic attraction members 212 are arranged in both the third through hole 112 and the fourth through hole 113.

[0088] As Figures 11-14 shown, the massage pad main body 100 has a conductive guide rail 105, and a conductive circuit 1051 is arranged on the conductive guide rail 105. The conductive circuit 1051 is electrically connected to a power source so that the conductive circuit 1051 is charged.

[0089] The power supply lines 114 of the driving devices of the head movement mechanism assembly 300 and the back movement mechanism assembly 200 (i.e., the back movement mechanism driving motor 202 and the head movement mechanism motor 304) are in sliding fit with the conductive guide rail 105 through a power-on box 111 and are electrically connected to the conductive circuit 1051.

[0090] As Figure 4 shown, for the convenience of distinction, the power-on box 111 of the head movement mechanism assembly 300 is the head power-on box 303, and the power-on box 111 of the back movement mechanism assembly 200 is the back power-on box 203. The head power-on box 303 and the back power-on box 203 have the same structure, and the size can be adjusted based on convenient installation.

[0091] When the head movement mechanism assembly 300 and the back movement mechanism assembly 200 move, the power-on box 111 moves along with the conductive guide rail 105 and remains electrically connected to the conductive circuit 1051, so that the power supply lines 114 of the back movement mechanism driving motor 202 and the head movement mechanism motor 304 can remain connected to the power source, avoiding the problem of mutual entanglement caused by the overlong power supply lines 114. Through the sliding conductive cooperation between the power-on box 111 and the conductive guide rail 105, the length of the power supply lines 114 can be shortened, and at the same time, they will not be mutually entangled, resulting in a circuit break.

[0092] Fixing grooves can be provided on the conductive guide rail 105, and the conductive line 1051 is threaded through the fixing grooves. The opening width of the fixing groove is relatively narrow, and the conductive line 1051 cannot be withdrawn through the open end of the fixing groove, and can only be inserted or withdrawn through the end of the fixing groove.

[0093] The power-on box 111 includes a slider 1113, an upper pressure plate 1111, a lower pressure plate 1114, a conductive column 1112, and a compression spring 1115. A counterbore 11131 and a conductive column hole 11132 provided in the counterbore 11131 are provided on the slider 1113. The conductive column hole 11132 is internally fitted with the conductive column 1112 and the compression spring 1115.

[0094] The upper pressure plate 1111 is fixedly connected to the corresponding head movement assembly 300 and the back movement assembly 200, so as to realize the synchronous movement of the power-on box 111 following the corresponding head movement assembly 300 and the back movement assembly 200.

[0095] The slider 1113 slides into the card slot of the upper pressure plate 1111 from one end of the upper pressure plate 1111 to realize the connection between the slider 1113 and the upper pressure plate 1111, and a sliding groove is formed between the slider 1113 and the upper pressure plate 1111, and the conductive guide rail 105 is arranged in the sliding groove. The lower pressure plate 1114 is fixed on the slider 1113. One end of the compression spring 1115 abuts against the conductive column 1112, and the other end abuts against the lower pressure plate 1114. The compression spring 1115 drives the conductive column 1112 to tightly press against the conductive line 1051 to realize the electrical connection between the conductive column 1112 and the conductive line 1051. The power supply line 114 is electrically connected to the conductive column 1112, and then the power supply is electrically connected to the back movement drive motor 202 and the head movement motor 304.

[0096] There are three conductive lines 1051 (respectively the positive line, the negative line, and the ground line), so three counterbores 11131 can be correspondingly provided on the slider 1113, and two conductive column holes 11132 can be provided in each counterbore 11131, that is, two conductive columns 1112 can be configured for each conductive line 1051 to be connected thereto to improve the connection reliability. The conductive column holes 11132 in each counterbore 11131 can be staggered from each other, that is, the conductive columns 1112 are staggered from each other in the sliding direction to reduce the risk of jamming.
