[0002] There are many massage chairs with massage functions on the market. In the prior art, in order to improve the comfort of the massage module and increase the massage mode, the massage module of some massage chairs has the following functions: (1) massage function, that is, the massage head of the massage module can move (for example, rotate, vibrate); (2) wandering function, that is, the massage module can move relative to other parts of the massage chair (such as the backrest, seat cushion), thereby changing the massage area of ​​the massage module for the user. However, in order to integrate the above two functions, the massage module of the massage chair needs to be equipped with more parts and drive mechanisms, which leads to a high structural complexity and cost of the massage module. Utility Model Content

To this end, the utility model proposes a massage module, which has the above two functions and has fewer driving mechanisms, and the structural complexity and cost of the massage module are both low.

[0040] Figure 1 FIG. 1 shows a portion of a chair 101 in one embodiment of the present invention, wherein the chair 101 includes a massage module 102 in any of the following embodiments. Figure 1 In the embodiment, the massage module 102 is installed on the front side of the backrest 131 of the chair 101, and the massage module 102 is mainly used to massage the back and waist of the user. In other embodiments, the massage module 102 can also be installed on the seat cushion or other parts of the chair 101.

[0041] Figure 2 The massage module 102 of one embodiment of the utility model is shown, and the massage module 102 includes a track 104 and a walking unit 103 that can move along the track 104. The track 104 can be fixed on the backrest 131, and the track 104 is vertically arranged (such as Figure 1 In other embodiments, the track 104 may also extend in a horizontal direction or in a direction inclined to the horizontal plane. Figure 2 and Figure 3 As shown, the walking unit 103 includes a housing 105, a massage head 106, a driving mechanism 107, a massage transmission mechanism 108, a walking member 109 and a clutch mechanism 110. The massage head 106 is provided with one or more, and at least a part of the massage head 106 is exposed outside the housing 105 so that the massage head 106 can contact the user's body. The driving mechanism 107, the massage transmission mechanism 108, the walking member 109, and the clutch mechanism 110 are all installed in the housing 105. The driving mechanism 107 is connected to the massage head 106 through the massage transmission mechanism 108. The driving mechanism 107 can drive the massage head 106 to move relative to the housing 105, and the moving massage head 106 can massage the user. The walking member 109 is connected to the track 104. Based on the cooperation between the walking member 109 and the track 104, when the walking member 109 moves relative to the housing 105, the walking member 109 will move along the track 104, so that the walking unit 103 moves along the track 104 as a whole, thereby changing the massage position of the massage head 106 on the user. The clutch mechanism 110 has a linkage state and a separation state. When the clutch mechanism 110 is in the linkage state, the driving mechanism 107 and the walking member 109 are connected by transmission through the clutch mechanism 110, and the driving mechanism 107 drives the walking member 109 to move relative to the housing 105, so that the walking unit 103 moves along the track 104; when the clutch mechanism 110 is in the separation state, the transmission connection between the driving mechanism 107 and the walking member 109 is disconnected. The clutch mechanism 110 can be manually switched by the user, or it can be switched by some power components (such as the linear drive member 126 mentioned below).

[0042] It should be noted that, no matter the clutch mechanism 110 is in a linkage state or a separation state, the drive mechanism 107 is in transmission connection with the massage head 106 through the transmission mechanism. That is, no matter which state the clutch mechanism 110 is in, as long as the drive mechanism 107 is running, the massage head 106 will move.

[0043] In addition, in this application, the transmission connection between two parts (or components, mechanisms) means that one of the parts (or components, mechanisms) can drive the other part (or component, mechanism) to move. The two are not necessarily directly connected, and the connection between the two can be direct or indirect, as long as one of them can eventually drive the other to move.

[0044] In order to realize the massage function and the walking function, two driving mechanisms (such as motors) and a clutch mechanism are usually provided in the prior art. One of the driving mechanisms is used to drive the massage head to move; the other driving mechanism cooperates with the clutch mechanism to control whether the massage module walks (walking means that the walking unit moves along the track). If the driving source included in the clutch mechanism is added, the massage module in the prior art is equivalent to requiring at least three driving mechanisms. Therefore, the number of driving mechanisms of the massage module in the prior art is relatively large, which leads to the structural complexity and high cost of the massage module.

[0045] For the massage module 102 of the present invention, when the clutch mechanism 110 is in the linkage state, the drive mechanism 107 drives the massage head 106 to move; when the clutch mechanism 110 is in the separation state, the drive mechanism 107 can drive the massage head 106 to move and can also drive the walking unit 103 to move. This drive mechanism 107 can be used to drive the massage head 106 to move and can also drive the walking unit 103 to move. Therefore, the number of drive mechanisms 107 of the massage module 102 of the present invention is small, and the structural complexity and cost of the massage module 102 are low.

[0046] The specific composition of each institution is introduced below.

[0047] The track 104 includes a rack 111 (eg Figure 2 As shown), the travel member 109 includes a travel gear 112 (as shown Figure 3As shown in the figure, the travel gear 112 is meshed with the rack 111. Based on the tooth transmission between the travel gear 112 and the rack 111, when the travel gear 112 rotates relative to the housing 105, the travel gear 112 rolls along the rack 111, so that the travel unit 103 moves along the length direction of the rack 111. Based on the characteristics of tooth transmission, this setting is conducive to improving the smoothness and stability of the travel unit 103 when it moves along the track 104, and is also conducive to improving the control accuracy of the position of the travel unit 103 on the track 104. In order to further improve the stability of the travel unit 103 when it moves along the track 104, the rack 111 can be provided with two (such as Figure 2 As shown), the travel gear 112 may also be provided with two (as shown Figure 3 shown).

[0048] In some embodiments, the travel unit 103 can be detached from the track 104. Figure 2 As shown, the massage module 102 further includes a guide block 201, which can slide along the track 104, and the guide block 201 is engaged with the travel unit 103 and fixed to the housing 105. When the user does not need the travel unit 103 or needs to repair the travel unit 103, the user can release the engagement between the travel unit 103 and the guide block 201 and remove the travel unit 103. The guide block 201 and the travel unit 103 are connected in an engaging manner, which is conducive to improving the convenience of disassembly and assembly of the travel unit 103.

[0049] Please refer to Fig. 9 , the guide block 201 includes a first clip 202, and the walking unit 103 includes a second clip 203 and an unlocking button 206. The first clip 202 is cylindrical, and an annular groove 204 is provided on the outer peripheral surface of the first clip 202. The second clip 203 is movably connected to the shell 105. For example, the second clip 203 is arranged in a certain slide groove of the shell 105 and can slide left and right. The second clip 203 can switch between a locked position and an unlocked position. When the second clip 203 is in the locked position, the second clip 203 is engaged with the first clip 202; more specifically, a portion of the first and second clips 203 are engaged in the annular groove 204. Fig. 9, the second clamping member 203 is in the clamping position. When the second clamping member 203 is in the unlocking position, the second clamping member 203 and the first clamping member 202 are separated from each other (i.e., the two are released from the clamping connection), and the user can now separate the walking unit 103 from the guide block 201. At least a portion of the unlocking button 206 is exposed outside the housing 105, and the portion of the unlocking button 206 outside the housing 105 can be pressed (for example, by the user's hand), so that the unlocking button 206 drives the second clamping member 203 to move from the locked position to the unlocked position. Since the walking unit 103 is provided with the unlocking button 206, the user can release the clamping connection between the first clamping member 202 and the second clamping member 203 by pressing the button. Providing the unlocking button 206 is conducive to improving the convenience of disassembly of the walking unit 103.

[0050] The matching relationship between the unlocking button 206 and the second clamping member 203 is as follows: Fig.10 As shown. The unlock button 206 has a first inclined surface 207, and the second clamping member 203 has a second inclined surface 208. The first inclined surface 207 and the second inclined surface 208 are used to fit each other. When the unlock button 206 is pressed, the first inclined surface 207 pushes the second inclined surface 208 to move, so that the second clamping member 203 moves laterally, and then the second clamping member 203 moves from the locked position to the unlocked position. Fig.10 As shown, in some embodiments, there are two first clamping members 202, two second clamping members 203, and the two second clamping members 203 are located between the two first clamping members 202. When the unlocking button 206 is pressed, the two second clamping members 203 move from their respective locking positions to their respective unlocking positions at the same time.

[0051] like Fig.10 As shown, in some embodiments, the walking unit 103 further includes an elastic member 205. The elastic member 205 is connected to the first clamping member 202. After the user releases the pressing of the unlocking button 206, the elastic force of the elastic member 205 is used to move the second clamping member 203 from the unlocking position to the locking position. In this way, the elastic member 205 can reset the second clamping member 203 to the locking position, and the user does not need to manually pull out the unlocking button 206 to reset the second clamping member 203, which is conducive to improving the installation convenience of the walking unit 103.

[0052] exist Fig.10In the illustrated embodiment, the elastic member 205 is accommodated in a cavity surrounded by two second clamping members 203 (the cavity is not specifically shown), and both ends of the elastic member 205 are respectively connected to the two first clamping members 202. As the unlocking button 206 is pressed, the elastic member 205 is gradually compressed; after the pressing is released, the compressed elastic member 205 stretches, thereby opening the two second clamping members 203 from each other, and then resetting the second clamping members 203 to their respective unlocking positions.

[0053] In other embodiments, the connection method of the elastic member 205 may be different from that in the above embodiments. For example, in other embodiments, there may be only one first clamping member 202, and there may be only one second clamping member 203, one end of the elastic member 205 is connected to the second clamping member 203, and the other end of the elastic member 205 is connected to the inner wall surface of the housing 105 or other parts fixed in the housing 105. In addition, in the process of the elastic member 205 driving the second clamping member 203 to reset to the unlocked position, the deformation of the elastic member 205 is not necessarily elongation, and the deformation of the elastic member 205 may also be set to contraction.

[0054] Please refer to Figure 3 The driving mechanism 107 includes a rotating motor 114 and a main worm 115. The massage transmission mechanism 108 includes a first worm gear 113 and a screw 116. The first worm gear 113 is rotatably connected to the housing 105, and the first worm gear 113 and the main worm 115 are meshed with each other. The screw 116 is transmission-connected to the first worm gear 113, and the screw 116 is disposed on the massage head 106 (such as Figure 2 ), and the screw 116 is threadedly connected to the massage head 106 (the massage head 106 is provided with a threaded hole). The rotary motor 114 can drive the main worm 115 to rotate, so that the first worm gear 113 and the screw 116 rotate, so that the massage head 106 moves along the axial direction of the screw 116. By controlling whether the rotary motor 114 rotates forward or reverse, the moving direction of the massage head 106 on the screw 116 can be controlled. Therefore, the driving mechanism 107 can drive the massage head 106 to move forward and backward to achieve a massage function.

[0055] like Figure 5As shown, in some embodiments, the walking unit 103 further includes a constraint plate 117, which is connected to the massage head 106, and the constraint plate 117 can move along the axial direction of the screw 116 with the massage head 106. For example, the end of the constraint plate 117 is stuck in a certain annular groove of the massage head 106, so that the massage head 106 can rotate relative to the constraint plate 117. In the case where there are two massage heads 106 and two screws 116, the constraint plate 117 is penetrated by two screws 116 at the same time, and the constraint plate 117 will not rotate with the screw 116 or the massage head 106. The screw 116 includes a first end and a second end, the first end is the rear end of the screw 116, and the second end is the front end of the screw 116. In the process of the massage head 106 moving from the first end to the second end, the distance between the massage head 106 and the housing 105 gradually increases. When the massage head 106 moves to the second end, the second end and the restraining plate 117 clamp the massage head 106 together, and under the friction between the second end and the massage head 106, the massage head 106 rotates together with the screw 116. In this way, the massage head 106 can move forward and backward and rotate, and the massage head 106 can provide more massage modes.

[0056] Please combine Figure 3 and Figure 5 The massage transmission mechanism 108 further includes a first gear 133, a second gear 134, a connecting gear 132 and a third gear 135. Figure 3 The first gear 133 is not shown. The position of the first gear 133 can be referred to as Figure 5 .like Figure 5 As shown, the first gear 133 and the first worm gear 113 are relatively fixed and coaxially arranged, the first gear 133 and the second gear 134 are meshed, the second gear 134 and the third gear 135 are meshed, and the connecting gear 132 and the third gear 135 are meshed. The third gear 135 and the screw rod 116 are fixed to each other and coaxially arranged, and the third gear 135 is arranged at the first end (rear end) of the screw rod 116. The first worm gear 113, the first gear 133, the second gear 134, the connecting gear 132, the third gear 135 and the screw rod 116 are sequentially connected. The "sequential transmission connection" here refers to the transmission path of power. The power provided by the driving mechanism 107 can be sequentially transmitted to the first worm gear 113, the first gear 133, the second gear 134, the connecting gear 132, the third gear 135 and the screw rod 116. The meaning of "sequential transmission connection" mentioned below can refer to the above explanation.

[0057] It should be noted that the drive mechanism 107 and the massage transmission mechanism 108 can also be set in other forms. In other embodiments, the first worm gear 113 and the main worm 115 of the drive mechanism 107 can be replaced by gears. The number of gears can be adjusted appropriately, and the massage transmission mechanism 108 does not necessarily need to include the first gear 133, the second gear 134, the connecting gear 132 and the third gear 135 at the same time. For example, the massage transmission mechanism 108 may also only include the connecting gear 132 and the third gear 135, and the connecting gear 132 is directly fixed relative to the first worm gear 113 and is coaxially arranged. In addition, the diameter, number of teeth, and position of the gear can also be flexibly adjusted according to the layout requirements of the various components in the housing 105 and the walking speed requirements of the walking unit 103.

[0058] The transmission cooperation between the clutch mechanism 110 and the massage transmission mechanism 108 can be set as a gear transmission. Figure 3 As shown, the clutch mechanism 110 includes a clutch gear 118. In this embodiment, no matter the clutch mechanism 110 is in a linkage state or a separation state, the connecting gear 132 is meshed with the clutch gear 118. When the clutch mechanism 110 is in a linkage state, the connecting gear 132, the clutch gear 118 and the traveling member 109 are sequentially connected in transmission, and the driving mechanism 107 can drive the traveling member 109 to rotate so that the traveling unit 103 moves along the track 104. When the clutch mechanism 110 is in a separation state, the clutch gear 118 and the connecting gear 132 are separated from each other (the two are not meshed with each other), and at this time, the driving mechanism 107 can only drive the massage head 106 to move, and cannot drive the traveling member 109 to rotate.

[0059] Please combine Figure 3 and Figure 4 The massage module 102 also includes a second worm gear 119 and a secondary worm 120 that mesh with each other. The secondary worm 120 meshes with the second worm gear 119. The second worm gear 119 and the walking member 109 are fixed to each other and arranged coaxially. When the clutch mechanism 110 is in a linkage state, the clutch gear 118 and the secondary worm 120 are connected in transmission. The walking unit 103 also includes a fourth gear 136. The transmission connection between the clutch gear 118 and the secondary worm 120 is realized through the fourth gear 136. The fourth gear 136 is coaxially arranged with the second worm and relatively fixed. When the clutch mechanism 110 is in a linkage state, the connecting gear 132 meshes with the clutch gear 118, and the clutch gear 118 meshes with the fourth gear 136. When the clutch mechanism 110 is in the disengaged state, the transmission connection between the clutch gear 118 and the auxiliary worm 120 is disconnected, and the auxiliary worm 120 and the second worm gear 119 are both stationary relative to the housing 105, so that the position of the travel unit 103 on the track 104 is fixed.

[0060] It should be noted that there is a self-locking effect between the worm wheel and the worm, and the rotation of the worm wheel cannot drive the worm to rotate in the opposite direction. This self-locking effect makes the auxiliary worm 120 and the second worm wheel 119 stationary relative to the housing 105. Since the second worm wheel 119 is stationary, the traveling gear 112 is also stationary relative to the housing 105, so that the traveling unit 103 is fixed relative to the track 104. Even if the track 104 is set vertically, the traveling unit 103 will not fall down due to its own gravity. When the traveling unit 103 does not need to move, the traveling unit 103 can be fixed in the required position, so that the user can continuously massage the body part that needs to be massaged.

[0061] The following describes how to switch the position of the clutch gear 118. Figure 7 and Figure 8 As shown, the walking unit 103 also includes a sliding block 121 and a movable pin 125. The movable pin 125 is interconnected with the clutch gear 118, and the two can move synchronously in the second direction. The sliding block 121 is slidably connected to the housing 105, and the sliding block 121 includes a first abutting surface 122, a second abutting surface 123 and a transition surface 124, and the first abutting surface 122 and the second abutting surface 123 are both spaced apart in the first direction and spaced apart in the second direction. The second direction is perpendicular to the first direction, the axial direction of the clutch gear 118 is the second direction, and the central axis of the clutch gear 118 and the central axis of the connecting gear 132 are parallel to each other. The two ends of the transition surface 124 are respectively connected to the first abutting surface 122 and the second abutting surface 123, and the transition surface 124 is inclined relative to the first direction. In the present embodiment, the sliding block 121 is provided with a slide groove, the movable pin 125 is slidably arranged in the slide groove, and the first abutting surface 122, the second abutting surface 123 and the transition surface 124 are all part of the wall surface of the slide groove. The first abutting surface 122 and the second abutting surface 123 are parallel, and the transition surface 124 is inclined relative to the first two. In order to facilitate the movable pin 125 to keep tight against the first abutting surface 122 or the second abutting surface 123, the present embodiment is provided with a slide groove. In other embodiments, the sliding block 121 may also not be provided with a slide groove, and the first abutting surface 122, the second abutting surface 123 and the transition surface 124 may all be set as the outer surface of the sliding block 121, and accordingly, the elastic force of a certain elastic element (such as a spring) may be used to keep the movable pin 125 tight against the first abutting surface 122 or the second abutting surface 123.

[0062] like Figure 7 and Figure 8As shown, when a clutch mechanism 110 is in a linkage state, the movable pin 125 corresponding to the clutch mechanism 110 abuts against the first abutting surface 122, the clutch gear 118 of the clutch mechanism 110 is in transmission connection with the traveling member 109 (the clutch gear 118 and the fourth gear 136 are meshed), and the driving mechanism 107 can drive the traveling member 109 to rotate so that the traveling unit 103 moves along the track 104. When a clutch mechanism 110 is in a disengaged state, the movable pin 125 abuts against the second abutting surface 123, and the transmission connection between the clutch gear 118 and the traveling member 109 is disconnected (the clutch gear 118 and the fourth gear 136 are disengaged). In this way, by pushing the sliding block 121 to move, the state of the clutch mechanism 110 can be switched. Since the sliding block 121 moves along the first direction, the housing 105 needs to reserve a smaller movable space for the sliding block 121 in the second direction. The above design is conducive to reducing the size of the walking unit 103 in the second direction, that is, reducing the thickness of the walking unit 103.

[0063] The sliding block 121 can be pushed or pulled by the user. Alternatively, in order to improve the convenience of use of the walking unit 103, the sliding block 121 can also be driven by a power source. The user can control the operation of the power source by a remote control or other means to control whether the walking unit 103 moves. For example, the walking unit 103 also includes a linear drive member 126 (such as Figure 3 and Figure 4 As shown in FIG. 1 , a linear drive member 126 is connected to the sliding block 121, and the linear drive member 126 is used to drive the sliding block 121 to move along a first direction so that the movable pin 125 is transferred between the first abutting surface 122 and the second abutting surface 123. The linear drive member 126 can be configured as a screw module, a belt module, a linear motor, an electromagnet, a cylinder, a hydraulic cylinder, etc.

[0064] In some embodiments, two massage heads 106 are provided. Two massage transmission mechanisms 108 are provided, and the two massage transmission mechanisms 108 are respectively a first transmission mechanism and a second transmission mechanism; Figure 3 For example, the massage transmission mechanism 108 on the left is the first transmission mechanism, and the massage transmission mechanism 108 on the right is the second transmission mechanism. The driving mechanism 107 includes a rotating motor 114 and two main worms 115. The two main worms 115 are respectively connected to the two ends of the rotating motor 114. The rotating motor 114 can drive the two main worms 115 to rotate synchronously. The two main worms 115 are respectively the first worm and the second worm. Figure 3For example, the main worm 115 on the left is the first worm, and the main worm 115 on the right is the second worm. The first worm and the second worm have opposite rotation directions, and the two first worm wheels 113 also need to be adapted to the corresponding main worm 115; the rotation direction refers to the spiral direction of the spiral line of the outer peripheral surface of the worm, not the direction when the worm rotates. The first worm is connected to one of the massage heads 106 through the first transmission mechanism, and the second worm is connected to the other massage head 106 through the second transmission mechanism. There are two clutch mechanisms 110, and the two clutch mechanisms 110 are respectively the first clutch mechanism and the second clutch mechanism. The clutch mechanism 110 on the left is the first clutch mechanism, and the clutch mechanism 110 on the right is the second clutch mechanism. This arrangement can increase the number of massage heads 106, thereby enhancing the massage area and massage effect of the massage module 102. In addition, the two massage heads 106 are driven by the same motor, and the two massage heads 106 do not need to be driven by two motors respectively. This is conducive to reducing the number of motors of the massage module 102, thereby helping to reduce the cost of the massage module 102.

[0065] Since the rotation directions of the first worm and the second worm are opposite, when the first worm, the first transmission mechanism, the first clutch mechanism 110 and the traveling member 109 are sequentially connected, the rotating motor 114 drives the first worm to rotate along the reference direction, so that the traveling member 109 rotates along the third direction; when the second worm, the second transmission mechanism, the second clutch mechanism 110 and the traveling member 109 are sequentially connected, the rotating motor 114 drives the second worm to rotate along the reference direction, so that the traveling member 109 rotates along the fourth direction. The fourth direction is opposite to the third direction. The movement direction of the traveling unit 103 when the traveling member 109 rotates along the third direction (for example, upward movement) is opposite to the movement direction of the traveling unit 103 when the traveling member 109 rotates along the fourth direction (for example, downward movement).

[0066] The reference direction can be clockwise or counterclockwise (from a left-viewing angle). If the third direction is clockwise, then the fourth direction is counterclockwise; if the third direction is counterclockwise, then the fourth direction is clockwise. The reference direction in the above text is not specifically limited. The above text only wants to express that whether the first worm or the second worm is connected to the walking member 109 in a transmission connection, the rotation direction of the first worm and the second worm is the same. This means that no matter in which direction the walking unit 103 moves, the rotating motor 114 drives the two main worms 115 to rotate in a fixed direction. This embodiment does not change the walking direction of the walking unit 103 by changing the rotation direction of the rotating motor 114, but changes the walking direction of the walking unit 103 by switching the clutch mechanism 110 (clutch gear 118) connected to the walking member 109 in a transmission connection. This embodiment is conducive to reducing the difficulty of controlling the rotating motor 114.

[0067] exist Figure 7 and Figure 8 In the illustrated embodiment, two first abutting surfaces 122 are provided, and two transition surfaces 124 are also provided. The two transition surfaces 124 are symmetrically arranged based on the second abutting surface 123, and the two first abutting surfaces 122 are symmetrically arranged based on the second abutting surface 123. Two movable pins 125 are provided, and two clutch mechanisms 110 (clutch gears 118) are also provided. In this way, by controlling the position of a sliding block 121, it is possible to select which clutch mechanism 110 (clutch gear 118) is connected to the walking member 109 in transmission, thereby controlling the walking direction of the walking unit 103.
