[0002] The massage movements of massage chairs currently on the market generally include three types, namely 2D movement, 3D airbag movement and mechanical 3D movement. Among them, since the 3D airbag movement can realize the flexible massage function of the mechanical 3D movement and the cost is better than the mechanical 3D movement, the 3D airbag movement has become a cost-effective choice.

[0043] The core of the present utility model lies in providing a 3D airbag movement to simplify the structure of the 3D airbag movement.

[0044] Another core of the present utility model lies in providing a massage chair including the above - mentioned 3D airbag movement.

[0045] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not impose any limitation on the content of the utility model described in the claims. Further, all the contents of the configurations shown in the following embodiments are not necessarily essential for the solution of the utility model described in the claims. It should be noted that for the sake of convenience of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments and the features in the embodiments of the present utility model can be combined with each other.

[0046] As Figures 1 - 3 shown, the embodiment of the present utility model discloses a 3D airbag movement, which includes a movement base 200, a movement assembly 100 and an airbag assembly.

[0047] Among them, an upper sliding wheel set 500 and a lower sliding wheel set 400 are arranged on the movement base 200, and the upper sliding wheel set 500 and the lower sliding wheel set 400 are used to realize the movement of the 3D airbag movement. It should be noted that at least one of the upper sliding wheel set 500 and the lower sliding wheel set 400 is used to realize the input of power, that is, one of them can be connected to the walking motor to drive the entire 3D airbag movement to walk on the massage chair frame of the massage chair to massage different areas of the user's back.

[0048] The movement assembly 100 includes a movement mounting seat 101 and a movement component 102 disposed on the movement mounting seat 101. The specific structure of the movement component 102 can be the same as the movement component in the prior art, and will not be repeated herein. In order to accommodate the movement component 102, the movement mounting seat 101 can be designed as a box body structure, and the movement component 102 is placed in the movement mounting seat 101 to protect some parts of the movement component 102. In addition, it should be noted that the massage part of the movement component 102 needs to extend outside the box body of the movement mounting seat 101 to achieve massage work for the user.

[0049] One end of the movement mounting seat 101 is rotatably connected to the transmission shaft of one of the upper sliding wheel set 500 and the lower sliding wheel set 400. Figure 1 In the illustrated solution, the movement mounting seat 101 is rotatably arranged on the transmission shaft of the lower sliding wheel assembly 400, so that the upper end of the movement mounting seat 101 can move away from and close to the movement base 200. Of course, the movement mounting seat 101 can also be rotatably arranged on the transmission shaft of the upper sliding wheel assembly 500, so that the lower end of the movement mounting seat 101 can move away from and close to the movement base 200.

[0050] The airbag assembly includes an airbag 300 and an inflation / deflation device 600 for inflating and deflating the airbag 300. The airbag 300 is disposed between the movement mounting base 101 and the movement base 200. The airbag 300 is clamped between the movement mounting base 101 and the movement base 200. Therefore, by controlling the inflation state of the airbag 300, the swing angle of the movement mounting base 101 can be controlled. When it is necessary to increase the massage intensity, the inflation / deflation device 600 can be used to inflate the airbag 300, so that the airbag 300 expands outward, squeezing the movement mounting base 101 to swing outward, thereby increasing the massage intensity. Correspondingly, when it is necessary to reduce the massage intensity, the inflation / deflation device 600 can deflate the airbag 300, so that the airbag 300 contracts. Due to the loss of the extrusion of the airbag 300, under the extrusion of the user's back, the movement mounting base 101 swings inward, thereby reducing the massage intensity. In addition, since the air in the airbag 300 is compressible, when the force acting on the airbag 300 becomes larger due to the user's backward leaning on the back, the air in the airbag 300 can also be compressed, causing the airbag 300 to deform and producing a flexible massage effect without causing pain caused by rigid connection.

[0051] In the 3D airbag movement provided by the present utility model, an upper sliding wheel set 500 and a lower sliding wheel set 400 are disposed on the movement base 200, and the transmission shaft of one of the upper sliding wheel set 500 and the lower sliding wheel set 400 is used as the swing shaft of the movement assembly 100, that is, the movement assembly 100 is rotatably disposed on the transmission shaft of one of the upper sliding wheel set 500 and the lower sliding wheel set 400, thus eliminating the need for a separate swing shaft and simplifying the structure of the 3D airbag movement. The airbag 300 is disposed between the movement mounting base 101 and the movement base 200. When the inflation / deflation device 600 inflates the airbag 300, it can drive the movement assembly 100 to swing away from the movement base 200, thereby increasing the massage intensity; when the inflation / deflation device 600 deflates the airbag, it can cause the movement assembly 100 to swing towards the movement base 200, thereby reducing the massage intensity, and the user can select a massage intensity that suits them according to their needs.

[0052] The 3D airbag movement can adjust the inflation state of the airbag 300 by manually controlling the inflation and deflation duration of the inflation / deflation device 600 for the airbag 300, and then control the massage intensity. If the inflation time is too long, it will cause the airbag 300 to be over-inflated, and then cause the massage balls of the movement assembly 102 to be in an extended state for a long time, resulting in too large a massage intensity and affecting the user experience; in addition, the same is true when deflating, and there is also a situation of over-deflation due to inaccurate control, resulting in too small a massage intensity and affecting the user experience. Therefore, manually controlling the inflation and deflation duration results in a poor user experience.

[0053] Based on this, the 3D airbag movement disclosed in the embodiments of the present utility model may further include a barometric pressure sensor 608 for detecting the pressure inside the airbag 300. When the pressure value detected by the barometric pressure sensor 608 exceeds the first preset pressure value, the air charging and discharging device 600 deflates the airbag 300.

[0054] Correspondingly, when the pressure value detected by the barometric pressure sensor 608 is lower than the second preset pressure value, the air charging and discharging device 600 inflates the airbag 300, and the first preset pressure value is greater than the second preset pressure value.

[0055] In this embodiment, the barometric pressure sensor 608 is used to detect the barometric pressure value of the airbag 300, so as to judge the pressure state of the airbag 300. Those skilled in the art can understand that the higher the barometric pressure value of the airbag 300, the more inflated the airbag 300 is, and the greater the massage force can be generated; the lower the barometric pressure value of the airbag 300, the more contracted the airbag 300 is, and the smaller the massage force can be generated.

[0056] In addition, when the user's back presses the movement assembly 100, the movement assembly 100 presses the airbag 300. At this time, the barometric pressure value detected by the barometric pressure sensor 608 will also increase, that is, the barometric pressure value will also increase by pressing the airbag 300. At this time, the massage force exerted by the movement component 102 on the user's back is also relatively large. Therefore, whether the airbag 300 is inflated or the back presses the movement assembly 100, the massage force exerted on the user's back will become larger. These two ways of changing the massage force can both detect the change in the barometric pressure value of the airbag 300 through the barometric pressure sensor 608.

[0057] In this embodiment, two thresholds (the first preset pressure value and the second preset pressure value) are calibrated in total. The first preset pressure value is greater than the second preset pressure value. When the pressure value detected by the barometric pressure sensor 608 exceeds the first preset pressure value, the air charging and discharging device 600 deflates the airbag 300. When the pressure value detected by the barometric pressure sensor 608 is lower than the second preset pressure value, the air charging and discharging device 600 inflates the airbag 300. The solution disclosed in this embodiment can keep the pressure value of the airbag 300 between the first preset pressure value and the second preset pressure value. If the first preset pressure value and the second preset pressure value can be calibrated according to one's own requirements for the massage force, the 3D airbag movement can control the airbag 300 between the first preset pressure value and the second preset pressure value according to the pressure value detected by the barometric pressure sensor 608, and then keep the massage force within the calibrated range.

[0058] During specific use, during the walking massage process of the 3D airbag movement mechanism, due to the physiological curve of the human back, as the 3D airbag movement mechanism moves and contacts different positions on the back during the walking process, and because the back has a physiological curve, the contact force with the back will change when contacting different positions on the back. When the contact force increases, the user will feel that the massage intensity increases and causes pain. At this time, the pressure value detected by the air pressure sensor 608 increases and exceeds the first preset pressure value. Therefore, the air charging and discharging device 600 is activated to deflate the airbag 300, thereby reducing the massage intensity and relieving the discomfort caused by excessive massage intensity. When the contact force decreases, the user will feel that the massage intensity decreases and the massage effect is reduced. At this time, the pressure value detected by the air pressure sensor 608 decreases and is lower than the second preset pressure value. Therefore, the air charging and discharging device 600 is activated to inflate the airbag 300, thereby increasing the massage intensity and improving the massage effect.

[0059] As Figure 5 shown, in this embodiment, the air charging and discharging device 600 may include an air inflation pump 601, an air deflation pump 602, a one-way valve 604, and a solenoid valve 605.

[0060] Among them, the air inflation pump 601, the one-way valve 604, and the air charging port 301 of the airbag 300 are sequentially connected. Specifically, the air outlet of the air inflation pump 601 is connected to the air inlet of the one-way valve 604 through a trachea 603, and the air outlet of the one-way valve 604 is connected to the air charging port 301 of the airbag 300. In this embodiment, a one-way valve 604 is connected in series between the air inflation pump 601 and the airbag 300. In the air inflation direction, the one-way valve 604 is in a conducting state, and in the other direction, the one-way valve 604 is in a cut-off state. During inflation, the air inflation pump 601 works, and the inflation air flow enters the airbag 300 through the one-way valve 604 and the air charging port 301, thereby increasing the air pressure in the airbag 300 and making the airbag 300 gradually fill. After inflation is completed, the air inflation pump 601 stops working. Since the one-way valve 604 is in a cut-off state in the direction from the airbag 300 to the air inflation pump 601, the air in the airbag 300 will not leak through the one-way valve 604, and thus the pressure in the airbag 300 can be maintained.

[0061] The air deflation pump 602, the solenoid valve 605, and the air deflation port 303 of the airbag 300 are sequentially connected. Specifically, the air inlet of the air deflation pump 602 is connected to the air outlet of the solenoid valve 605 through a trachea 605, and the air inlet of the solenoid valve 605 is connected to the air deflation port 303 of the airbag 300. In this embodiment, a solenoid valve 605 is connected in series between the air deflation pump 602 and the airbag 300. The deflation timing can be controlled by controlling the energized and de-energized state of the solenoid valve 605. By the operation of the air deflation pump 602, the exhaust speed can be accelerated under the action of the negative pressure provided by the air deflation pump 602.

[0062] During deflation, the deflation air pump 602 operates, and at the same time, the solenoid valve 605 is energized, causing the solenoid valve 605 to be in a conducting state. The gas in the airbag 300 is accelerated and discharged by the deflation air pump 602 through the solenoid valve 605 and the deflation pipe orifice 303, thereby reducing the air pressure in the airbag 300 and causing the airbag 300 to gradually contract. After deflation is completed, the deflation air pump 602 stops operating, and at the same time, the solenoid valve 605 is de-energized, causing the solenoid valve 605 to be in a cut-off state. Since the solenoid valve 605 is in a cut-off state, the air in the airbag 300 will not leak out through the solenoid valve 605, and thus the pressure in the airbag 300 can be maintained. In this embodiment, the deflation air pump 602 is added, and under the action of the deflation air pump 602, the speed of relieving pressure for the airbag 300 can be increased, and then the massage intensity can be quickly reduced to a suitable range for the user, avoiding affecting the user's comfort due to excessive intensity.

[0063] The air pressure sensor 608 is communicated with the pressure measuring pipe orifice 302 of the airbag 300. The air pressure sensor 608 can be connected to the circuit board 607. By communicating the pressure input pipe orifice of the air pressure sensor 608 with the pressure measuring pipe orifice 302 of the airbag 300, the air pressure sensor 608 can collect the pressure value of the airbag 300.

[0064] As Figure 4 shown, in a specific embodiment of the present utility model, the movement base 200 has an installation groove 201, and the airbag 300 is fixed in the installation groove 201. In this embodiment, by providing the installation groove 201 on the movement base 200 and fixing the airbag 300 in the installation groove 201, the side wall of the installation groove 201 has a limiting effect on the airbag 300, preventing the airbag 300 from expanding around when it is filled. Since the side of the airbag 300 is restricted by the side wall of the installation groove 201, when it inflates and expands, it expands more towards the outside of the installation groove 201, and then pushes the movement assembly 100 to swing outward, increasing the massage intensity.

[0065] Furthermore, the movement base 200 is provided with an installation platform 205 outside the installation groove 201, and the air charging and discharging device 600 is arranged on the installation platform 205. Since the air charging and discharging device 600 needs to be connected to power lines and some pipelines, in this embodiment, an installation platform 205 is separately provided for the air charging and discharging device 600, avoiding the influence of the deformation of the airbag 300 on the power lines, pipelines, etc.

[0066] As Figure 4 and Figure 5As shown, since the inflating air pump 601 and the deflating air pump 602 are usually cylindrical structures, it is not easy to install their cylindrical surfaces on a plane. In this embodiment, in order to facilitate the fixing of the inflating air pump 601 and the deflating air pump 602 on the installation platform 205, two air pump embedding holes 206 penetrating through the wall thickness are provided in the installation platform 205. The inflating air pump 601 and the deflating air pump 602 of the air charging and discharging device 600 are respectively embedded in their corresponding air pump embedding holes 206 and fixed by fasteners.

[0067] Mounting ear plates are provided on both the inflating air pump 601 and the deflating air pump 602, and fastening holes are provided in the mounting ear plates. After the inflating air pump 601 and the deflating air pump 602 are respectively embedded in their corresponding air pump embedding holes 206, the mounting ear plates on the inflating air pump 601 and the deflating air pump 602 are attached to the plate surface of the installation platform 205. Then, the fasteners are passed through the fastening holes in the mounting ear plates and the fastening holes in the installation platform 205 for fixation.

[0068] Communication holes for the respective pipelines of the airbag 300 to extend are provided on the side wall of the installation groove 201. That is, the air charging pipe orifice 301, the pressure measuring pipe orifice 302, and the air discharging pipe orifice 303 all extend out of the installation groove 201 through the communication holes on the side wall of the installation groove 201 to be connected to the air charging and discharging device 600 on the installation platform 205.

[0069] As Figure 2 and Figure 4 As shown, in a specific embodiment of the present utility model, the transmission shaft of the upper sliding wheel group 500 is the upper transmission shaft 501, and the transmission shaft of the lower sliding wheel group 400 is the lower transmission shaft. Upper support holes 203 for supporting the upper transmission shaft 501 and lower support holes 202 for supporting the lower transmission shaft are provided on the movement mechanism base 200.

[0070] Drive gears are provided on both the upper transmission shaft 501 and the lower transmission shaft. It should be noted that the lower transmission shaft may not be provided with a drive gear. When installing the 3D airbag movement mechanism onto the massage chair frame of the massage chair, the sliding wheels 502 of the upper sliding wheel group 500 and the lower sliding wheel group 400 cooperate with the guide rails on the massage chair frame to limit the movement of the 3D airbag movement mechanism along the extension direction of the guide rails. The drive gears on the upper transmission shaft 501 and the lower transmission shaft are engaged with the drive racks on the massage chair frame.

[0071] The upper driving shaft 501 is used for driving connection with the walking motor, that is, the upper sliding wheel set 500 is the driving wheel to drive the 3D airbag movement mechanism to move along the guide rail on the massage chair frame. Since the upper driving shaft 501 realizes the input of power and needs to bear a greater torque, a plurality of spaced-apart rotating shaft fixing plates 204 are arranged in the installation groove 201, and the upper driving shaft 501 is rotatably supported on the rotating shaft fixing plates 204. In this embodiment, by arranging a plurality of rotating shaft fixing plates 204, a more stable and reliable support is provided for the upper driving shaft 501.

[0072] A hollow groove is formed on the bottom wall of the installation groove 201, and the rotating shaft fixing plate 204 is arranged in the hollow groove. Forming a hollow groove on the bottom wall of the installation groove 201 helps prevent the transmission gear on the upper driving shaft 501 from being blocked, facilitating meshing with the transmission rack. It should be noted that if a transmission gear is also provided on the lower driving shaft, the same design as that of the upper driving shaft 501 can be adopted, that is, a hollow groove also needs to be provided at the position where the lower driving shaft is installed to facilitate the meshing of the transmission gear on the lower driving shaft with the transmission rack.

[0073] As Figure 5 shown, airbag fixing pieces are provided at both ends of the airbag 300, and the airbag fixing pieces are fixed to the bottom wall of the installation groove 201 through fasteners. Fastening holes need to be provided on the bottom wall of the installation groove 201, and corresponding fastening holes also need to be provided on the airbag fixing pieces. When installing the airbag 300, the fastening holes on the airbag fixing piece can be aligned with the fastening holes on the bottom wall of the installation groove 201, and then fixed by passing through the fasteners.

[0074] As Figure 6 shown, an embodiment of the present utility model also discloses a massage chair, which includes a massage chair frame 2 and a 3D airbag movement mechanism 1 movably arranged on the massage chair frame 2, and the 3D airbag movement mechanism 1 is the 3D airbag movement mechanism 1 disclosed in the above embodiment.

[0075] A guide rail and a transmission rack are arranged on the massage chair frame 2, the transmission gear on the 3D airbag movement mechanism 1 meshes with the transmission rack, and the sliding wheels of the upper sliding wheel set 500 and the lower sliding wheel set 400 cooperate with the guide rail, thereby realizing the walking of the 3D airbag movement mechanism 1.

[0076] The massage chair provided by the present utility model has the above 3D airbag movement mechanism, so it has all the technical effects of the above 3D airbag movement mechanism, which will not be elaborated herein.
