[0076] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0077] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0078] Please refer to the following: Figure 1 and Figure 2 This utility model provides a massage waist support mechanism 1. The massage component 11 includes a mounting base plate 10, a plurality of massage components 11 and a first adjustment component 13. The plurality of massage components 11 are disposed on the mounting base plate 10 at intervals along the width direction X. The first adjustment component 13 is disposed on the mounting base plate 10 and connected to the plurality of massage components 11. The first adjustment component 13 is configured to drive the plurality of massage components 11 to slide relative to the mounting base plate 10, so that some of the massage components 11 slide in opposite or opposite directions to the remaining massage components 11.

[0079] The massage lumbar support mechanism 1 provided in the first aspect of this utility model, by setting a first adjustment component 13, can drive the massage component 11 to move and adjust the position of the massage component 11 relative to the mounting base plate 10. When the user uses the massage function of the massage lumbar support mechanism 1, the position of the massage component 11 can be adjusted so that the massage component 11 is aligned with the area to be massaged by the user. Furthermore, there are multiple massage components 11, and multiple massage modules can simultaneously provide massage to multiple massage areas of the user. The positions of multiple massage components 11 are all adjustable, which improves the flexibility of the massage lumbar support mechanism 1. The first adjustment component 13 can simultaneously drive multiple massage components 11 to slide, and some massage components 11 slide in opposite or opposite directions to the remaining massage components 11, so that some massage components 11 and the remaining massage components 11 are brought closer to each other or moved away from each other. That is, when using the massage lumbar support mechanism 1, the distance between the two parts of the massage components 11 can be adjusted for users of different body types, so that the two parts of the massage components 11 can be aligned with different massage areas of the user, improving the flexibility of the massage lumbar support mechanism 1 and enhancing the user experience. For example, for users with a larger build, the two massage components 11 can be moved further apart to increase the distance between them, while for users with a thinner build, the two massage components 11 can be moved closer together to reduce the distance between them.

[0080] In this embodiment, the mounting base plate 10 is a structure used to support the massage component 11 and the first adjustment component 13, etc. The mounting base plate 10 can be a plate structure, a block structure or a frame structure, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0081] Optionally, the number of massage components 11 can be two, three, four, or five, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made. For example, when there are two massage components 11, one massage component 11 slides in opposite or opposite directions with the other massage component 11. When there are four massage components 11, one massage component 11 can slide in opposite or opposite directions with the other three massage components 11, or two massage components 11 can slide in opposite or opposite directions with the other two massage components 11.

[0082] Specifically, the sliding of one portion of the massage component 11 in opposite directions to the remaining portion of the massage component 11 means that the portion of the massage component 11 slides away from each other, increasing the distance between the two massage components. Conversely, the sliding of one portion of the massage component 11 in opposite directions to the remaining portion of the massage component 11 means that the portion of the massage component 11 slides closer to each other, decreasing the distance between the two massage components.

[0083] In some embodiments, there are two massage components 11. The first adjustment component 13 is configured to drive the two massage components 11 to slide relative to the mounting base 10 along the width direction X of the mounting base 10, so that the two massage components 11 move away from or closer to each other, and the two massage components 11 slide the same distance in the width direction X. The two massage components 11 sliding the same distance in the width direction X means that the distance one massage component 11 moves to the left is equal to the distance the other massage component 11 moves to the right.

[0084] The first adjustment component 13 allows the two massage components 11 to be moved closer or further apart. That is, when using the lumbar massage mechanism 1, the distance between the two massage components 11 can be adjusted for users of different body types, ensuring that the two massage components 11 are aligned with the user's two massage areas (usually the sides of the user's waist), thus improving the user experience. For example, for overweight users, the two massage components 11 can be moved further apart, increasing the distance between them; for thinner users, the two massage components 11 can be moved closer together, decreasing the distance between them.

[0085] Therefore, the massage lumbar support mechanism 1 of this application can adjust the position of the two massage components 11 in the width direction X according to the body shape of different users, so that the massage lumbar support mechanism 1 can be used by different users and the application range of the massage lumbar support mechanism 1 is wider.

[0086] It is understood that the width direction X of the mounting base plate 10 mentioned above is also the width direction X of the massage waist support mechanism 1, that is, the left-right direction of the massage waist support mechanism 1. This left-right direction refers to the left-right direction corresponding to the user when using the massage waist support mechanism 1 for massage. The above direction is an example for the purpose of facilitating understanding of the structure and function of the massage waist support mechanism 1 of this utility model, and does not limit the scope of this application.

[0087] In some embodiments, the first adjustment component 13 includes a first motor 130 and a first transmission mechanism 131 disposed on the mounting base plate 10. The first transmission mechanism 131 includes a gear structure 131a and two racks 131b. The two racks 131b are slidably disposed on the massage component 11 along the width direction X. The two racks 131b are respectively connected to the two massage components 11.

[0088] The gear structure 131a is meshed between the two racks 131b. The gear structure 131a is connected to the first motor 130. The first motor 130 is configured to drive the gear structure 131a to rotate, so that the two racks 131b drive the two massage components 11 to slide relative to the mounting base plate 10 in opposite or opposite directions.

[0089] In this way, the first motor 130 can drive the gear structure 131a to rotate, and the gear structure 131a can simultaneously drive the two racks 131b to move, so that the two racks 131b slide in opposite directions in the first slide groove 105, thereby causing the two massage components 11 to move away from each other, or causing the two racks 131b to slide in opposite directions in the first slide groove 105, thereby causing the two massage components 11 to move closer to each other. Only one first motor 130 and one gear structure 131a are needed to drive the two racks 131b to move simultaneously, thereby providing power to the two massage components 11. The structure is relatively simple and compact, and can effectively utilize the space on the rear side 101 of the mounting base plate 10, which is conducive to the miniaturization design of the massage waist support mechanism 1.

[0090] In other embodiments, the first adjustment component 13 may also be a linear drive motor, which drives the massage component 11 to move; or, the first adjustment component 13 may also be a manual push rod, which drives the massage component 11 to move by manually operating the manual push rod.

[0091] Optionally, the first motor 130 may be an electric motor or a pneumatic motor, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0092] Optionally, the gear structure 131a may include one or more gears, which may be selected according to the specific circumstances, and are not specifically limited in this embodiment. When the gear structure 131a has multiple gears, such as two, three, four or five gears, the deceleration of the first motor 130 can be achieved through the cooperation of multiple gears.

[0093] In some embodiments, the mounting substrate 10 has an upper side 102 and a lower side 103 facing away from each other along the height direction Y of the mounting substrate 10, the first motor 130 is disposed near the lower side 103, and the gear structure 131a and two racks 131b are disposed near the upper side 102 relative to the first motor 130.

[0094] It is understandable that the aforementioned height direction Y is also the height direction Y of the massage waist support mechanism 1, that is, the up and down direction of the massage waist support mechanism 1. This up and down direction refers to the up and down direction of the user when using the massage waist support mechanism 1 for massage.

[0095] Since the first motor 130 is typically relatively heavy, positioning it near the lower side 103 of the mounting base 10 allows for a more reasonable weight distribution of the massage lumbar support mechanism 1. This means the center of gravity of the massage lumbar support mechanism 1 is positioned relatively lower on the lower side 103, preventing it from becoming top-heavy and making it difficult to place on a sofa or chair. Simultaneously, positioning the gear structure 131a and the two racks 131b near the upper side 102 of the first motor 130 allows for efficient use of the space on the rear side 101 of the mounting base 10. This also ensures that the racks 131b align with the second housing 110b of the massage housing 110 in the height direction Y, facilitating connection with the massage housing 110.

[0096] In some embodiments, the axial direction of the shaft of the first motor 130 is parallel to the width direction X, and the first transmission mechanism 131 further includes a worm 131c, one end of which is connected to the shaft of the first motor 130, and the other end of which is meshed with the gear structure 131a.

[0097] Since the rack 131b moves along the width direction X, the gear in the gear structure 131a needs to rotate around the thickness direction Z. Typically, the axial direction of the first motor 130's shaft needs to be parallel to the thickness direction Z. By setting a worm gear 131c, which can transmit power between two intersecting shafts, the axial direction of the first motor 130's shaft can be set parallel to the width direction X, and it can also drive the gear in the gear structure 131a to rotate around the thickness direction Z. By setting the axial direction of the first motor 130's shaft parallel to the width direction X, i.e., the first motor 130 is placed parallel to the width direction X, the space required by the first motor 130 in the thickness direction Z can be reduced, which helps to reduce the size of the massage lumbar support mechanism 1 in the thickness direction Z.

[0098] It is understandable that the aforementioned thickness direction Z is also the thickness direction Z of the massage waist support mechanism 1, that is, the front-back direction of the massage waist support mechanism 1. This front-back direction refers to the direction that the user faces or moves away from the user's waist when using the massage waist support mechanism 1 for massage.

[0099] In some embodiments, the mounting base 10 has a front side 100 and a rear side 101 that are opposite to each other along the thickness direction Z of the mounting base 10. The massage assembly 11 is located on the front side 100, and the first motor 130, gear structure 131a, and two racks 131b are located on the rear side 101. Herein, the front side 100 refers to the side of the massage lumbar support mechanism 1 that faces the user when in use, and the rear side 101 refers to the side of the massage lumbar support mechanism 1 that faces away from the user when in use.

[0100] In this way, on the one hand, it facilitates the installation of the massage component 11 and the first adjustment component 13 on the mounting base plate 10, and makes reasonable use of the space in the thickness direction Z of the mounting base plate 10, reducing the space in the width direction X of the massage lumbar support mechanism 1 required by the massage component 11 and the first adjustment component 13. This helps to reduce the size of the massage lumbar support mechanism 1 in the width direction X, making it easier to place the massage lumbar support mechanism 1 on a sofa or chair. On the other hand, since the massage component 11 usually has components such as an electric motor, pneumatic motor, or air pump 120 to realize functions such as height adjustment or rotation, this application sets the first adjustment component 13 and the massage component 11 apart through the mounting base plate 10, which can reduce the possible mutual interference between the first motor 130 of the first adjustment component 13 and the electric motor, pneumatic motor, or air pump 120 of the massage component 11 during operation, and helps to improve the service life of the first adjustment component 13 and the massage component 11.

[0101] Please refer to the following: Figures 1 to 6In some embodiments, the mounting base 10 is provided with a first sliding portion 10c, and the massage assembly 11 is provided with a second sliding portion 115. The second sliding portion 115 is slidably connected to the first sliding portion 10c along the width direction X of the mounting base 10, so that the massage assembly 11 is movably connected to the mounting base 10 along the width direction X. By providing the first sliding portion 10c and the second sliding portion 115, a sliding engagement between the massage assembly 11 and the mounting base 10 can be achieved.

[0102] Optionally, one of the first sliding part 10c and the second sliding part 115 may be a protrusion, and the other may be a groove. Alternatively, the first sliding part 10c and the second sliding part 115 may be two slidably connected surfaces, etc. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0103] Optionally, the number of the first sliding part 10c and the second sliding part 115 may be one or more, and the specific selection can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0104] In some embodiments, the mounting substrate 10 is provided with a plurality of first sliding portions 10c, and the massage assembly 11 is provided with a plurality of second sliding portions 115. Each second sliding portion 115 is slidably connected to each first sliding portion 10c along the width direction X of the mounting substrate 10, so that the massage assembly 11 is movably connected to the mounting substrate 10 along the width direction X. At least two second sliding portions 115 are arranged along the height direction Y of the mounting substrate 10 to limit the position of the massage assembly 11 in the height direction Y.

[0105] Multiple second sliding portions 115 restrict the position of the massage component 11 in the height direction Y, making it difficult for the massage component 11 to move relative to the mounting base plate 10 in the height direction Y, thereby reducing the possibility of the massage component 11 shifting in the height direction Y during sliding in the width direction X, and improving the stability of the massage component 11 in the width direction X.

[0106] In some embodiments, the front side 100 is provided with two first sliding grooves 105 extending to the rear side 101. The two first sliding grooves 105 are spaced apart along the height direction Y, and at least partially staggered in the width direction X. Two massage components 11 are slidably connected to the two first sliding grooves 105 respectively, and two racks 131b are respectively disposed in the two first sliding grooves 105. In this embodiment, the first sliding groove 105 is a first sliding part 10c.

[0107] By setting two first sliding grooves 105, the two massage components 11 can slide relative to the two first sliding grooves 105. At the same time, the two racks 131b can also slide relative to the first sliding grooves 105, and the racks 131b and the massage components 11 can be connected through the first sliding grooves 105, so that the racks 131b can drive the massage components 11 to slide. Moreover, the two first sliding grooves 105 are spaced apart along the height direction Y, which can make reasonable use of the space of the mounting base plate 10 in the height direction Y, and at the same time reduce the space occupied by the two first sliding grooves 105 in the width direction X. This helps to reduce the size of the massage lumbar support mechanism 1 in the width direction X, making it easier to place the massage lumbar support mechanism 1 on a sofa or chair.

[0108] In some embodiments, the rear side 101 is provided with two second slide grooves 107, which are respectively connected to two first slide grooves 105. The two second slide grooves 107 are at least partially corresponding in the height direction Y, and the two racks 131b are respectively slidably connected to the two second slide grooves 107.

[0109] By providing two second slide grooves 107, each second slide groove 107 can accommodate two racks 131b, and each rack 131b can slide relative to the two second slide grooves 107 in the width direction X. Since the racks 131b themselves have a certain length, the length of the second slide groove 107 should be the sum of the length of the racks 131b and the design stroke of the massage component 11, so that the two second slide grooves 107 are at least partially staggered in the width direction X. This can reduce the space required on the mounting base plate 10 for the two second slide grooves 107 in the width direction X, thereby helping to reduce the size of the massage lumbar support mechanism 1 in the width direction X, making it easier to place the massage lumbar support mechanism 1 on a sofa or chair.

[0110] In some embodiments, the massage component 11 has a first protrusion 1150 protruding towards the first slide groove 105. The first protrusion 1150 is slidably connected to the corresponding first slide groove 105 and is connected to the corresponding rack 131b. In this embodiment, the first protrusion 1150 is a second sliding part 115.

[0111] By providing the first protrusion 1150, the first protrusion 1150 can slide in conjunction with the first slide groove 105, making the massage component 11 move more smoothly in the width direction X. At the same time, the first protrusion 1150 passes through the first slide groove 105 and the second slide groove 107, thereby connecting the massage component 11 with the rack 131b, so that when the rack 131b slides in the width direction X, it can drive the massage component 11 to move in the width direction X.

[0112] In other embodiments, a first groove 105 may be provided on the massage component 11, and a first protrusion 1150 may be provided on the front side 100.

[0113] In some embodiments, the massage component 11 has a second protrusion 1151 protruding towards the front side 100, and the first protrusion 1150 and the second protrusion 1151 are spaced apart along the height direction Y. The front side 100 has two third sliding grooves 104, and each second protrusion 1151 is slidably connected to the corresponding third sliding groove 104 along the width direction X. In this embodiment, the second protrusion 1151 is a second sliding part 115, and the third sliding groove 104 is a first sliding part 10c.

[0114] By providing the second protrusion 1151, the second protrusion 1151 can slide and engage with the third slide groove 104, and the third slide groove 104 can restrict the position of the second protrusion 1151 in the height direction Y, making the massage component 11 move more smoothly in the width direction X. Furthermore, the first protrusion 1150 and the second protrusion 1151 are spaced apart in the height direction Y, and the multiple second sliding portions 115 restrict the position of the massage component 11 in the height direction Y, making it difficult for the massage component 11 to move relative to the mounting base plate 10 in the height direction Y. This reduces the possibility of the massage component 11 shifting in the height direction Y during sliding in the width direction X, and improves the stability of the massage component 11's movement in the width direction X.

[0115] In some embodiments, the massage assembly 11 includes a massage housing 110 and a massage head 111. The massage housing 110 is provided with a plurality of second sliding portions 115, and the massage head 111 is disposed at one end of the massage housing 110 along the height direction Y. At least one second sliding portion 115 is disposed adjacent to the massage head 111.

[0116] The massage head 111 is a component used to massage the user's massage area. The massage housing 110 is used to support the massage head 111 and other components. Multiple second sliding portions 115 are provided on the massage housing 110 to achieve a sliding connection between the massage housing 110 and the mounting base plate 10 in the width direction X. Since the massage head 111 is a component subjected to a lot of force (such as pressure from the user) when massaging the waist support mechanism 1, the massage head 111 is more prone to shifting in the height direction Y when the massage housing 110 slides relative to the mounting base plate 10 in the width direction X. By placing at least one second sliding portion 115 near the massage head 111, the shifting of the massage head 111 in the height direction Y when the massage housing 110 and the mounting base plate 10 slide in the width direction X can be reduced, improving the stability of the massage head 111's movement in the width direction X, and allowing for more precise adjustment of the massage head 111's position.

[0117] Optionally, the arrangement of at least one second sliding portion 115 adjacent to the massage head 111 means that there may be one second sliding portion 115 adjacent to the massage head 111, or there may be multiple second sliding portions 115 adjacent to the massage head 111, such as two second sliding portions 115 adjacent to the massage head 111 or three second sliding portions 115 adjacent to the massage head 111, etc.

[0118] In some embodiments, the mounting base 10 has an upper side 102 and a lower side 103 that are opposite to each other along the height direction Y. The massage head 111 is disposed at one end of the massage housing 110 near the upper side 102. The massage assembly 11 also includes a second adjustment assembly 113. Please refer to [link to relevant documentation]. Figure 8 The second adjustment component 113 includes a second motor 113a and a second transmission mechanism 113b. The second motor 113a is located at one end of the massage housing 110 near the lower side 103, and the second transmission mechanism 113b is located at one end of the massage housing 110 near the upper side 102. The second transmission mechanism 113b is connected to the massage head 111. The second motor 113a is connected to the second transmission mechanism 113b. The second motor 113a is configured to drive the second transmission mechanism 113b to move, so that the massage head 111 rotates around the thickness direction Z of the mounting base plate 10.

[0119] In this way, the second motor 113a can provide power to drive the massage head 111 to rotate around the thickness direction Z through the second transmission mechanism 113b, thereby realizing the kneading function of the massage head 111. By placing the second motor 113a at one end of the massage housing 110 near the lower side 103, and placing the second transmission mechanism 113b and the massage head 111 at one end of the massage housing 110 near the upper side 102, on the one hand, since the second motor 113a is usually relatively heavy, placing the second motor 113a at the lower side 103 near the mounting base plate 10 can make the weight distribution of the massage lumbar support mechanism 1 more reasonable, avoiding the "top-heavy" situation of the massage lumbar support mechanism 1, which would make it inconvenient to place the massage lumbar support mechanism 1 on a sofa or chair. On the other hand, the massage head 111 is located at one end near the upper side 102, giving it a certain height in the height direction Y, which is beneficial for aligning it with the user's massage area. For example, when the massage lumbar support mechanism 1 is applied to the massage lumbar support, and the massage lumbar support is placed on a sofa or chair, the massage head 111 has a certain height in the height direction Y, which is beneficial for the massage head 111 to massage the user's waist. The second transmission mechanism 113b is also located at one end of the massage housing 110 near the upper side 102, corresponding to the massage head 111, which facilitates connection with the massage head 111 and enables transmission of the massage head 111.

[0120] In other embodiments, the second adjustment component 113 may also include only the second motor 113a, which directly drives the massage head 111 to rotate. Alternatively, the second adjustment component 113 may also be a rocker arm, which drives the massage head 111 to rotate by manually rotating the rocker arm.

[0121] Please refer to the following: Figures 5 to 7 In some embodiments, the massage housing 110 includes a first housing 110a and a second housing 110b connected to each other. The first housing 110a includes a first portion 1101 and a second portion 1102 arranged along the height direction Y. The first portion 1101 is closer to the upper side 102 than the second portion 1102. The second housing 110b includes a third portion 1103 and a fourth portion 1104 arranged along the height direction Y. The first portion 1101 and the third portion 1103 enclose a first chamber 1105, and the second portion 1102 and the fourth portion 1104 enclose a second chamber 1106. The second chamber 1106 communicates with the first chamber 1105. A second transmission mechanism 113b is disposed in the first chamber 1105, a second motor 113a is disposed in the second chamber 1106, and a massage head 111 is disposed in the first portion 1101. A plurality of second sliding portions 115 are disposed in the second housing 110b, and at least one second sliding portion 115 is located in the third portion 1103.

[0122] By configuring the massage housing 110 as a first housing 110a and a second housing 110b, it is convenient to install components (such as the second motor 113a, the second transmission mechanism 113b, etc.) into the first chamber 1105 and the second chamber 1106 formed between the first housing 110a and the second housing 110b. The second adjustment component 113 is disposed in the first housing 110a and the second housing 110b, which can protect the second adjustment component 113 and isolate the second motor 113a from other components, thereby reducing the impact of the vibration generated by the second motor 113a during operation on other components. Meanwhile, by dividing the first housing 110a into a first part 1101 and a second part 1102, and the second housing 110b into a third part 1103 and a fourth part 1104, the first part 1101 and the second part 1102 of the first housing 110a, together with the third part 1103 and the fourth part 1104 of the second housing 110b, form a first chamber 1105 and a second chamber 1106, which can respectively accommodate the second transmission mechanism 113b and the second motor 113a. In addition, the first chamber 1105 and the second chamber 1106 are arranged in the height direction Y, which allows the second motor 113a to be placed in the second chamber 1106 near the lower side 103 of the mounting base plate 10. Since the second motor 113a is usually relatively heavy, the weight distribution of the massage lumbar support mechanism 1 can be more reasonable, avoiding the "top-heavy" situation of the massage lumbar support mechanism 1, which would make it inconvenient to place the massage lumbar support mechanism 1 on a sofa or chair.

[0123] In some embodiments, the first portion 1101 has a first side 110d and a second side 110e that are opposite to each other along the thickness direction Z. The first side 110d is opposite to the second side 110e and is away from the third portion 1103. The first side 110d is provided with a mounting surface 1100, and the massage head 111 is disposed on the mounting surface 1100. The second side 110e and the inner wall surface of the third portion 1103 enclose each other to form a first chamber 1105. Herein, the first side 110d refers to the side of the first portion 1101 facing the user when the massage waist support mechanism 1 is in use, and the second side 110e refers to the side of the first portion 1101 facing away from the user when the massage waist support mechanism 1 is in use.

[0124] By making the first part 1101 have a first side 110d and a second side 110e along the thickness direction Z, the two sides of the first part 1101 have different functions. On the one hand, the first side 110d of the first part 1101 is provided with a mounting surface 1100, which can serve to support the massage head 111 and provide mounting space for the massage head 111. On the other hand, the second side 110e of the first part 1101 and the inner wall surface of the third part 1103 enclose a first chamber 1105, which can accommodate the second transmission mechanism 113b. This makes full use of the space of the first part 1101 in the thickness direction Z, realizes structural reuse, and helps to simplify the structural design of the massage waist support mechanism 1.

[0125] Please refer to it again. Figures 3 to 6 In some embodiments, the second sliding portion 115 provided in the third portion 1103 is configured as a second protrusion 1151 protruding toward the mounting substrate 10, wherein a first sliding portion 10c is configured as a third groove 104, and the second protrusion 1151 is slidably connected to the third groove 104.

[0126] By providing the second protrusion 1151, the second protrusion 1151 can slide and engage with the third slide groove 104, and the third slide groove 104 can limit the position of the second protrusion 1151 in the height direction Y, so that the massage assembly 11 moves more smoothly in the width direction X. Furthermore, the second protrusion 1151 is located in the third part 1103, that is, the second protrusion 1151 is located adjacent to the massage head 111. The second protrusion 1151 can provide better support for the third part 1103, which can reduce the movement of the massage head 111 in the height direction Y when the massage housing 110 mounting base plate 10 slides in the width direction X, thereby improving the stability of the massage head 111 moving in the width direction X.

[0127] In some embodiments, the inner wall surface of the third part 1103 is provided with a first groove 11032 to form a second protrusion 1151 on the outer wall of the third part 1103. The massage assembly 11 also includes a connecting post 116, which is rotatably disposed on the first part 1101. One end of the connecting post 116 is connected to the massage head 111, and the other end of the connecting post 116 is connected to the second transmission mechanism 113b and located in the first groove 11032.

[0128] The connecting post 116 serves as a transmission mechanism, driving the massage head 111 to rotate around the thickness direction Z under the influence of the second transmission mechanism 113b. Since the connecting post 116 requires a certain amount of space, a first groove 11032 is provided on the inner wall of the third part 1103 to form a second protrusion 1151 on the outer wall of the third part 1103. The first groove 11032 can accommodate the connecting post 116, meaning the internal space of the second protrusion 1151 can accommodate the connecting post 116. Simultaneously, the second protrusion 1151 can slide in conjunction with the third sliding groove 104, which restricts the position of the second protrusion 1151 in the height direction Y, making the massage housing 110 move more smoothly in the width direction X. By setting a first groove 11032 on the inner wall of the third part 1103 to form a second protrusion 1151 on the outer wall of the third part 1103 (for example, by stamping), the processing difficulty of the second protrusion 1151 can be reduced, and the structure of the second protrusion 1151 can be reused, which is beneficial to simplifying the structural design of the massage waist support mechanism 1.

[0129] In some embodiments, the upper side 102 of the mounting substrate 10 is provided with a first engaging portion 106, and the third portion 1103 is provided with a second engaging portion 11030 corresponding to the first engaging portion 106. The first engaging portion 106 is slidably connected to the second engaging portion 11030 along the width direction X, and the first engaging portion 106 is engaged with the second engaging portion 11030 so that the second engaging portion 11030 is fixed relative to the first engaging portion 106 in the thickness direction Z.

[0130] By engaging the first engaging portion 106 with the second engaging portion 11030, the second engaging portion 11030 can be fixed relative to the first engaging portion 106 in the thickness direction Z, thereby fixing the massage housing 110 relative to the mounting base 10 in the thickness direction Z. Through the engaging of the first engaging portion 106 with the second engaging portion 11030 and the sliding engagement of the second protrusion 1151 with the third sliding groove 104, the massage housing 110 can slide relative to the mounting base 10 in the width direction X, while also fixing the massage housing 110 relative to the massage base in the thickness direction Z and the height direction Y. The massage housing 110 is fixed on the mounting base 10, and further makes the massage housing 110 move more smoothly in the width direction X.

[0131] Optionally, one of the two types of the first engaging portion 106 can be a groove, and the other type can be a buckle or hook, etc. The specific type can be selected according to the actual situation, and no specific limitation is made in this embodiment.

[0132] In this embodiment, to prevent the engagement of the first engaging portion 106 and the second engaging portion 11030 from blocking the movement of the massage housing 110 in the width direction X, one of the first engaging portion 106 and the second engaging portion 11030 is a sliding groove. For example, the first engaging portion 106 is a sliding groove that extends along the width direction X, that is, the first engaging portion 106 and the second engaging portion 11030 are also equivalent to a set of first sliding portion 10c and second sliding portion 115.

[0133] In some embodiments, the second engaging portion 11030 and the second sliding portion 115 are arranged sequentially at intervals along the direction from the upper side 102 to the lower side 103.

[0134] The second engaging portion 11030 and the second sliding portion 115 are spaced apart in the height direction Y, which is equivalent to two second sliding portions 115 being spaced apart in the height direction Y. The second engaging portion 11030 and the second sliding portion 115 restrict the position of the massage housing 110 in the height direction Y, making it difficult for the massage housing 110 to move relative to the mounting base plate 10 in the height direction Y. This reduces the possibility of the massage assembly 11 shifting in the height direction Y during the sliding process in the width direction X, and improves the stability of the massage assembly 11 in the width direction X.

[0135] In some embodiments, the first engaging portion 106 is configured as a sliding groove, and the inner wall of the third sliding groove 104 has a first notch 1040 on the side near the upper side 102, the first notch 1040 communicating with the first engaging portion 106, and the inner wall of the third sliding groove 104 has a second notch 1041 on the side away from the upper side 102, and the second notch 1041 is provided corresponding to the first notch 1040 in the height direction Y.

[0136] Since the second engaging portion 11030 cannot be directly inserted into the first engaging portion 106 in the thickness direction Z, a first notch 1040 communicating with the first engaging portion 106 is provided on the side of the third sliding groove 104 near the upper side 102, and a second notch 1041 is provided on the side of the third sliding groove 104 away from the upper side 102. The first notch 1040 can avoid the second engaging portion 11030, and the second notch 1041 can avoid the second protrusion 1151. When installing the massage housing 110 onto the mounting base plate 10, the second engaging portion 11030 can be placed at the first notch 1040, the second protrusion 1151 can be placed at the second notch 1041, and then the massage housing 110 can be moved upward so that the second engaging portion 11030 is engaged into the first engaging portion 106, and the second protrusion 1151 is located in the third sliding groove 104, thereby completing the installation of the massage housing 110 on the mounting base plate 10.

[0137] In some embodiments, the third portion 1103 is provided with a rolling portion 11031 on the side facing the mounting substrate 10. The rolling portion 11031 is configured to abut against the mounting substrate 10 so as to rotate relative to the third portion 1103 when the third portion 1103 slides relative to the mounting substrate 10 in the width direction X.

[0138] By providing the rolling part 11031, when the massage housing 110 moves relative to the mounting base plate 10 in the width direction X, the rolling part 11031 can roll relative to the mounting base plate 10, which can reduce the friction generated when the massage housing 110 moves relative to the mounting base plate 10, which helps to make the sliding of the massage housing 110 in the width direction X more stable. At the same time, it also helps to reduce the energy loss of the second motor 113a, making the massage waist support mechanism 1 more energy-efficient.

[0139] Optionally, the rolling part 11031 can be a roller or a rolling shaft, etc., and the specific selection can be made according to the actual situation. In this example, no specific limitation is made.

[0140] Optionally, the number of rolling parts 11031 can be one or more, which can be selected according to the actual situation. When there are multiple rolling parts 11031, the multiple rolling parts 11031 can be arranged at intervals along the width direction X. The multiple rolling parts 11031 can better reduce the friction generated when the massage housing 110 moves relative to the mounting base plate 10. At the same time, the multiple rolling parts 11031 arranged at intervals along the width direction X can make reasonable use of the space of the massage housing 110 in the width direction X.

[0141] In some embodiments, the second sliding portion 115 and the rolling portion 11031 provided on the third portion 1103 are arranged at intervals along the direction from the upper side 102 to the lower side 103.

[0142] The rolling part 11031 and the second sliding part 115 are spaced apart in the height direction Y, which is equivalent to two second sliding parts 115 being spaced apart in the height direction Y. The rolling part 11031 and the second sliding part 115 restrict the position of the massage housing 110 in the height direction Y (the rolling part 11031 has a large frictional force relative to the mounting base plate 10 in the height direction Y), making it difficult for the massage housing 110 to move relative to the mounting base plate 10 in the height direction Y. This reduces the possibility of the massage assembly 11 shifting in the height direction Y during sliding in the width direction X, and improves the stability of the massage assembly 11 in the width direction X. In addition, the rolling part 11031, the second sliding part 115 (i.e., the second protrusion 1151) provided in the third part 1103, and the second engaging part 11030 achieve "three-point positioning" on the mounting base plate 10, which can better improve the stability of the massage housing 110 in the width direction X.

[0143] In some embodiments, at least one second sliding portion 115 is provided in the fourth portion 1104.

[0144] Both the third part 1103 and the fourth part 1104 are provided with at least one second sliding part 115. Thus, the massage housing 110 is provided with at least one second sliding part 115 at both ends in the height direction Y. The two second sliding parts 115 can reduce the movement of the third part 1103 and the fourth part 1104 in the height direction Y, respectively. That is, they can restrict the part of the massage housing 110 near the upper side 102 and the part near the lower side 103, respectively, and further improve the stability of the massage housing 110 in the width direction X.

[0145] Optionally, having at least one second sliding portion 115 in the fourth part 1104 means that there may be one second sliding portion 115 in the fourth part 1104, or there may be multiple second sliding portions 115 in the fourth part 1104, such as two second sliding portions 115 in the fourth part 1104 or three second sliding portions 115 in the fourth part 1104, etc.

[0146] In some embodiments, the second sliding portion 115 provided in the fourth portion 1104 is configured as a first protrusion 1150 protruding toward the mounting substrate 10, wherein a first sliding portion 10c is configured as a first groove 105, and the first protrusion 1150 is slidably connected to the first groove 105.

[0147] By providing a first protrusion 1150, the first protrusion 1150 can slide in conjunction with the first slide groove 105, and the first slide groove 105 can limit the position of the first protrusion 1150 in the height direction Y, making the massage component 11 move more smoothly in the width direction X. By providing a first adjustment component 13, the first adjustment component 13 can drive the first protrusion 1150 to move in the width direction X, thereby providing power for the movement of the massage component 11 in the width direction X. In addition, the first protrusion 1150 serves as both a component for sliding contact and a component for transmitting power, realizing structural reuse of the first protrusion 1150, which helps to simplify the structural design of the massage waist support mechanism 1.

[0148] In some embodiments, the mounting base plate 10 has a front side 100 and a rear side 101 that are opposite to each other along the thickness direction Z. A first groove 105 passes through the front side 100 and the rear side 101. The massage component 11 is located on the front side 100, the first adjustment component 13 is located on the rear side 101, and the first protrusion 1150 passes through the first groove 105. The front side 100 refers to the side of the massage lumbar support mechanism 1 that faces the user during use, and the rear side 101 refers to the side of the massage lumbar support mechanism 1 that faces away from the user during use.

[0149] In this way, on the one hand, it facilitates the installation of the massage component 11 and the first adjustment component 13 on the mounting base plate 10, and makes reasonable use of the space in the thickness direction Z of the mounting base plate 10, reducing the space in the width direction X of the massage lumbar support mechanism 1 required by the massage component 11 and the first adjustment component 13. This helps to reduce the size of the massage lumbar support mechanism 1 in the width direction X, making it easier to place the massage lumbar support mechanism 1 on a sofa or chair. On the other hand, by setting the first adjustment component 13 and the massage component 11 at intervals through the mounting base plate 10, it can reduce the possible mutual interference between the second motor 113a of the first adjustment component 13 and the second adjustment component 113 during operation, which helps to improve the service life of the first adjustment component 13 and the second adjustment component 113.

[0150] In some embodiments, the rear side 101 is provided with a second slide groove 107, which communicates with the first slide groove 105. The first adjustment component 13 includes a first motor 130 and a first transmission mechanism 131. The first transmission mechanism 131 includes a gear structure 131a and a rack 131b. The gear structure 131a is meshed with the rack 131b and connected to the first motor 130. The rack 131b is disposed in the second slide groove 107 and is connected to the first protrusion 1150. The first motor 130 is configured to drive the gear structure 131a to rotate, so that the rack 131b slides in the width direction X in the second slide groove 107. In this embodiment, the number of massage components 11 can be two, and the number of the first slide groove 105, the second slide groove 107, and the rack 131b is also two.

[0151] The first motor 130 drives the gear structure 131a to rotate, and the gear structure 131a simultaneously drives the rack 131b to move, causing the rack 131b to slide in the width direction X in the first slide groove 105, thereby driving the massage component 11 to slide in the width direction X. The second slide groove 107 serves to accommodate the rack 131b and provide guidance for the rack 131b. When there are two massage components 11, the gear structure 131a can cause the two racks 131b to slide in opposite directions in the first slide groove 105, thereby causing the two massage components 11 to move away from each other, or cause the two racks 131b to slide in opposite directions in the first slide groove 105, thereby causing the two massage components 11 to move closer to each other. Only one first motor 130 and one gear structure 131a are needed to simultaneously drive the two racks 131b to move, thereby providing power to the two massage components 11. The structure is relatively simple and compact, and can effectively utilize the space on the rear side 101 of the mounting base plate 10, which is beneficial to the miniaturization design of the massage waist support mechanism 1.

[0152] Optionally, the first motor 130 may be an electric motor or a pneumatic motor, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0153] Optionally, the gear structure 131a may include one or more gears, which may be selected according to the specific circumstances, and are not specifically limited in this embodiment. When the gear structure 131a has multiple gears, such as two, three, four or five gears, the deceleration of the first motor 130 can be achieved through the cooperation of multiple gears.

[0154] In some embodiments, the axial direction of the shaft of the first motor 130 is parallel to the thickness direction Z, and the first transmission mechanism 131 further includes a worm 131c, one end of which is connected to the shaft of the first motor 130, and the other end of which is meshed with the gear structure 131a.

[0155] Since the rack 131b moves along the width direction X, the gear in the gear structure 131a needs to rotate around the thickness direction Z. Typically, the axial direction of the first motor 130's shaft needs to be parallel to the thickness direction Z. By setting a worm gear 131c, which can transmit power between two intersecting shafts, the axial direction of the first motor 130's shaft can be set parallel to the width direction X, and it can also drive the gear in the gear structure 131a to rotate around the thickness direction Z. By setting the axial direction of the first motor 130's shaft parallel to the width direction X, i.e., the first motor 130 is placed parallel to the width direction X, the space required by the first motor 130 in the thickness direction Z can be reduced, which helps to reduce the size of the massage lumbar support mechanism 1 in the thickness direction Z.

[0156] In some embodiments, the first protrusion 1150 extends along the width direction X, and the two side walls of the first protrusion 1150 on opposite sides in the height direction Y are slidably connected to the first groove 105.

[0157] By extending the first protrusion 1150 along the width direction X, and having both side walls of the first protrusion 1150 slidably connected to the first groove 105 on opposite sides in the height direction Y, the contact area between the first protrusion 1150 and the first groove 105 on a plane perpendicular to the height direction Y can be increased, thereby enabling the first groove 105 to effectively limit the first protrusion 1150 in the height direction Y.

[0158] In some embodiments, along the direction from the upper side 102 to the lower side 103, the second sliding portion 115 and the rolling portion 11031 provided in the third portion 1103 and the second sliding portion 115 provided in the fourth portion 1104 are arranged at intervals in sequence.

[0159] The rolling part 11031 and the second sliding part 115 are spaced apart in the height direction Y, which is equivalent to two second sliding parts 115 being spaced apart in the height direction Y. The rolling part 11031 and the second sliding part 115 restrict the position of the massage housing 110 in the height direction Y (the rolling part 11031 has a large frictional force relative to the mounting base 10 in the height direction Y), making it difficult for the massage housing 110 to move relative to the mounting base 10 in the height direction Y. This reduces the possibility of the massage assembly 11 shifting in the height direction Y during sliding in the width direction X, and improves the stability of the massage assembly 11 in the width direction X. In addition, the rolling part 11031, the second sliding part 115 (i.e., the second protrusion 1151) provided in the third part 1103, and the second sliding part 115 (i.e., the first protrusion 1150) provided in the fourth part 1104 achieve "three-point positioning" on the mounting base 10, which can better improve the stability of the massage assembly 11 in the width direction X.

[0160] Please see Figure 7 In some embodiments, the massage assembly 11 includes a massage housing 110, a massage head 111, and an airbag device 112. The massage housing 110 is slidably disposed on the mounting base 10 along the thickness direction Z. The massage head 111 is movably connected to the massage housing 110. The airbag device 112 is disposed between the massage head 111 and the massage housing 110. The airbag device 112 is configured to be inflatable to push the massage head 111 along the thickness direction Z, so that the massage head 111 moves away from the massage housing 110.

[0161] By inflating the airbag device 112, the massage head 111 can be moved along the thickness direction Z when inflated, thus raising the height of the massage head 111. Conversely, the pneumatic component 12 can control the airbag device 112 to contract, allowing the massage head 111 to move along the thickness direction Z and lower its height. Therefore, when using the massage function of the lumbar massage mechanism 1, the user can adjust the pressure of the massage head 111 by adjusting its height, improving the flexibility of the lumbar massage mechanism 1. For example, raising the height of the massage head 111 results in a greater pressure felt by the user, while lowering it results in a less intense pressure.

[0162] Please refer to the following: Figure 1 and Figure 11 In some embodiments, the massage waist support mechanism 1 further includes a pneumatic component 12, which is disposed on the mounting base plate 10 and spaced apart from the second adjustment component 113. The pneumatic component 12 is connected to the airbag device 112 and is used to inflate the airbag device 112.

[0163] By providing the pneumatic component 12, the pneumatic component 12 can control the inflation of the airbag device 112. In addition, since the second adjustment component 113 and the pneumatic component 12 are prone to vibration during operation, by spacing the pneumatic component 12 and the second adjustment component 113 apart, the influence between the pneumatic component 12 and the second adjustment component 113 can be reduced, thereby improving the service life of the pneumatic component 12 and the second adjustment component 113.

[0164] In some embodiments, the massage housing 110 and the pneumatic component 12 are spaced apart on the same side of the mounting base 10. This arrangement, by spacing the massage housing 110 and the pneumatic component 12 on the same side of the mounting base 10, allows the second adjustment component 113 to be spaced apart from the pneumatic component 12, thereby reducing the influence between the pneumatic component 12 and the second adjustment component 113 and improving their service life. Furthermore, since the pneumatic component 12 and the airbag device 112 typically require a connecting air tube 122 to power the airbag device 112, placing the massage housing 110 and the pneumatic component 12 on the same side of the mounting base 10 simplifies the piping design, shortens the piping, and improves the safety of using the pneumatic component 12 and the airbag device 112.

[0165] In other embodiments, the massage housing 110 and the pneumatic assembly 12 may be disposed on different sides of the mounting base plate 10, so that the second adjustment assembly 113 and the pneumatic assembly 12 are spaced apart.

[0166] In some embodiments, the airbag device 112 and the second adjustment component 113 are arranged along the height direction Y in the massage housing 110, and the pneumatic component 12 and the second adjustment component 113 are spaced apart in the height direction Y. By arranging the airbag device 112, the pneumatic component 12, and the second adjustment component 113 in the height direction Y, on the one hand, a certain distance can be maintained between the second adjustment component 113 and the pneumatic component 12 in the height direction Y, thereby reducing the influence between the pneumatic component 12 and the second adjustment component 113 and improving the service life of the pneumatic component 12 and the second adjustment component 113. On the other hand, it can reduce the space occupied by the second adjustment component 113 and the airbag device 112 in the height direction Y of the massage lumbar support core 1, thereby reducing the size of the massage lumbar support core 1 in the height direction Y, thereby expanding the application scenarios of the massage lumbar support core 1. For example, it can be placed on a sofa or chair, or the massage lumbar support core 1 can be fixed to the waist of the human body by means of straps or other fixing methods.

[0167] In some embodiments, in the height direction Y, the mounting base plate 10 has an upper side 102 and a lower side 103 facing away from each other, the pneumatic assembly 12 and the airbag device 112 are disposed near the upper side 102, and the second adjustment assembly 113 is disposed near the lower side 103.

[0168] In this way, by ensuring that the second adjustment component 113 and the pneumatic component 12 are at a certain distance in the height direction Y, on the one hand, since the second adjustment component 113 is usually relatively heavy, placing the second adjustment component 113 near the lower side 103 of the mounting base 10 allows for a more reasonable weight distribution of the massage lumbar support mechanism 1, preventing it from being "top-heavy" and making it inconvenient to place on a sofa or chair. On the other hand, since the massage head 111 and the airbag device 112 are arranged in conjunction in the thickness direction Z, the massage head 111 is also positioned near the upper side 102 of the mounting base 10. This ensures that when the massage lumbar support mechanism 1 is placed on a sofa or chair, the massage head 111 has a certain height in the height direction Y, which is beneficial for the massage head 111 to massage the user's waist.

[0169] In some embodiments, the massage housing 110 is slidably disposed on the mounting base 10 along the width direction X. In this way, the position of the massage housing 110 relative to the mounting base 10 in the width direction X can be adjusted, thereby adjusting the position of the massage head 111 relative to the mounting base 10 in the width direction X. When the user uses the massage waist support mechanism 1, the position of the massage head 111 can be adjusted so that the massage head 111 massages the position that the user needs.

[0170] In some embodiments, the pneumatic assembly 12 includes an air pump 120, a valve 121, and an air pipe 122. The air pump 120 is disposed on the mounting base plate 10 and spaced apart from the second adjustment assembly 113. The valve 121 is connected to the air pump 120 via a conduit. One end of the air pipe 122 is connected to the valve 121, and the other end of the air pipe 122 is connected to the airbag device 112. At least a portion of the air pipe 122 is configured as a flexible conduit.

[0171] In this way, the air pump 120 can provide gas power to the airbag device 112. When the valve 121 is open, the air pump 120 and the airbag device 112 are connected, and the air tube 122 can guide the gas to be delivered to the airbag device 112. When the valve 121 is closed, the air pump 120 and the airbag device 112 are disconnected. In addition, since the massage housing 110 is slidably disposed on the mounting base plate 10 in the width direction X, that is, the airbag device 112 can move relative to the mounting base plate 10 in the width direction X, when the massage housing 110 moves in the width direction X, the end of the air tube 122 connected to the airbag device 112 will also move in the width direction X under the drive of the airbag device 112. By configuring at least a portion of the air tube 122 as a flexible tube, the air tube 122 can have a certain deformation, avoiding the phenomenon of the air tube 122 breaking during the movement of the massage housing 110.

[0172] Optionally, the entire trachea 122 can be configured as a flexible conduit, or only a portion of the trachea 122 can be configured as a flexible conduit. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0173] Optionally, the material of the flexible tube portion of the trachea 122 can be polyvinyl chloride or polyurethane, etc., which can be selected according to the actual situation, and is not specifically limited in this embodiment.

[0174] Optionally, valve 121 can be a solenoid valve or a manual valve, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0175] Please refer to the following: Figure 11 and Figure 12 In some embodiments, the mounting substrate 10 includes a main body 10a and a cover 10b. In the height direction Y, the main body 10a has an upper side 102 and a lower side 103 facing away from each other. The cover 10b is disposed on the main body 10a and close to the upper side 102 to form a receiving cavity 108 with at least a portion of the main body 10a. A pneumatic assembly 12 is disposed within the receiving cavity 108. The cover 10b is provided with clearance holes 109 (e.g., ...). Figure 12 As shown), the clearance hole 109 is connected to the receiving cavity 108. The clearance hole 109 is used for the air tube 122 of the pneumatic component 12 to pass through, so as to connect to the airbag device 112.

[0176] Thus, by providing the main body 10a and the cover 10b, the main body 10a can support components such as the massage assembly 11 and the first adjustment assembly 13. The receiving cavity 108 formed between the main body 10a and the cover 10b can accommodate the pneumatic assembly 12, while also protecting the pneumatic assembly 12 and isolating it from the second adjustment assembly 113, further reducing the influence between the pneumatic assembly 12 and the second adjustment assembly 113. By providing a clearance hole 109 on the cover 10b that communicates with the receiving cavity 108, the air tube 122 of the pneumatic assembly 12 can pass through the clearance hole 109 from the receiving cavity 108, thereby achieving communication with the airbag device 112.

[0177] Optionally, the cover portion 10b may form a receiving cavity 108 between itself and the entire main body portion 10a, or it may form a receiving cavity 108 between itself and a portion of the main body portion 10a. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0178] Optionally, the number of massage components 11 may be one or more, and the specific number can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0179] In some embodiments, there are multiple massage components 11, and in the width direction X, a pneumatic component 12 is disposed between the massage housings 110 of the multiple massage components 11. By providing multiple massage components 11, the massage waist support mechanism 1 can simultaneously massage multiple parts of the user's body. By disposing the pneumatic component 12 between the massage housings 110 of the multiple massage components 11, it is easier for the pneumatic component 12 to communicate with the massage housings 110 of each massage component 11 via an air pipe 122, thus reducing the required length of the air pipe 122.

[0180] For example, the number of massage components 11 can be two, three, or four. When there are two massage components 11, the pneumatic component 12 is disposed between the two massage components 11 in the width direction X, that is, there is one massage component 11 on each side of the pneumatic component 12 in the width direction X. When there are four massage components 11, the pneumatic component 12 can be disposed between two massage components 11 and two massage components 11 in the width direction X, that is, there are two massage components 11 on each side of the pneumatic component 12 in the width direction X. The pneumatic component 12 can also be disposed between one massage component 11 and three massage components 11, that is, there is one massage component 11 on each side of the pneumatic component 12 in the width direction X and three massage components 11 on each side.

[0181] In some embodiments, the cover portion 10b is provided with a connecting member 10d, and the air pipe 122 includes a main pipe 122a and a plurality of branch pipes 122b. The main pipe 122a passes through the clearance hole 109. One end of the main pipe 122a is connected to the valve 121 of the pneumatic component 12, and the other end of the main pipe 122a is connected to the connecting member 10d. The number of the plurality of branch pipes 122b is the same as the number of the plurality of airbag devices 112. One end of each branch pipe 122b is connected to each airbag device 112 in a corresponding manner, and the other end of each branch pipe 122b is connected to the connecting member 10d.

[0182] In this way, by setting up a connecting component 10d, which is connected to the valve 121 of the pneumatic component 12 via the main pipe 122a and to each airbag device 112 via the branch pipe 122b, the air pump 120, the valve 121 of the pneumatic component 12 are all connected to the multiple airbag devices 112. This enables the air pump 120 to provide air power to the multiple airbag devices 112, eliminating the need to set up multiple air pumps 120 to provide air power to the multiple airbag devices 112 respectively, thus simplifying the structure of the massage waist support mechanism 1.

[0183] Optionally, the connecting component 10d can be a multi-port connector or a multi-port valve, etc. The number of interfaces of the multi-port connector or multi-port valve is set according to the number of main pipe 122a and branch pipe 122b. For example, when there are two airbag devices 112 and two branch pipes 122b, the multi-port connector can be, for example, a three-way connector, or the multi-port valve can be, for example, a three-way valve.

[0184] In some embodiments, a first circuit board 10e is provided in the receiving cavity 108. The first circuit board 10e is electrically connected to the pneumatic assembly 12. In the thickness direction Z, the first circuit board 10e and the pneumatic assembly 12 are spaced apart.

[0185] Thus, by setting the first circuit board 10e, the first circuit board 10e can control the pneumatic assembly 12 to open or close, thereby controlling the position of the massage head 111 relative to the massage housing 110 in the thickness direction Z. Furthermore, by spacing the first circuit board 10e and the pneumatic assembly 12 in the thickness direction Z, the impact of vibrations generated during the operation of the pneumatic assembly 12 on the electronic components on the first circuit board 10e can be reduced, thereby improving the service life of the first circuit board 10e.

[0186] Optionally, the first circuit board 10e may be a flexible first circuit board 10e or a rigid first circuit board 10e, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0187] Please see Figure 13In some embodiments, the distance between the first circuit board 10e and the pneumatic component 12 in the thickness direction Z satisfies the relationship: 5mm ≤ D ≤ 20mm. On one hand, this ensures a certain distance between the first circuit board 10e and the pneumatic component 12 in the thickness direction Z, effectively reducing the impact of vibrations generated by the pneumatic component 12 during operation on the electronic components on the first circuit board 10e. On the other hand, it also prevents the distance between the first circuit board 10e and the pneumatic component 12 in the thickness direction Z from being too large, avoiding excessive space occupation in the thickness direction Z by the first circuit board 10e and the pneumatic component 12, which is beneficial for achieving a miniaturized design of the massage waist support mechanism 1.

[0188] For example, the distance between the first circuit board 10e and the pneumatic assembly 12 can be 5mm, 10mm, 15mm or 20mm, etc.

[0189] In some embodiments, the main body 10a has a first mounting groove 108a, the first circuit board 10e is disposed in the first mounting groove 108a, and the cover has a second mounting groove 108b. The second mounting groove 108b and the first mounting groove 108a together form a receiving cavity 108, and the pneumatic component 12 is disposed in the second mounting groove 108b. By providing the first mounting groove 108a on the main body 10a and the second mounting groove 108b on the cover, the first mounting groove 108a and the second mounting groove 108b together form a receiving cavity 108, thereby accommodating the first circuit board 10e and the pneumatic component 12. Furthermore, by opening a first mounting groove 108a on the main body 10a, on the one hand, the first mounting groove 108a can play a positioning role for the first circuit board 10e, making it easier to position and install the first circuit board 10e on the main body 10a; on the other hand, by making a part of the receiving cavity 108 utilize the space inside the main body plate, the height of the cover part 10b protruding relative to the front side 100 of the main body 10a can be reduced, which is beneficial for the cover part 10b to avoid the massage shell 110 that can slide in the width direction X.

[0190] In some embodiments, a buffer 10f is provided in the receiving cavity 108, the buffer 10f is disposed between the pneumatic assembly 12 and the first circuit board 10e, and / or, the buffer 10f is disposed between the pneumatic assembly 12 and the cover portion 10b.

[0191] In one example, a buffer 10f is disposed between the pneumatic assembly 12 and the first circuit board 10e. By providing the buffer 10f between the pneumatic assembly 12 and the first circuit board 10e, the buffer 10f can buffer and dampen the pneumatic assembly 12. On the one hand, it can further reduce the impact of vibrations generated during the operation of the pneumatic assembly 12 on the electronic components on the first circuit board 10e, thereby improving the service life of the first circuit board 10e. On the other hand, it can reduce the noise of the pneumatic assembly 12 during operation, improving the user experience.

[0192] In another example, the buffer 10f is disposed between the pneumatic assembly 12 and the cover portion 10b. By providing the buffer 10f between the pneumatic assembly 12 and the cover portion 10b, the buffer 10f can buffer and dampen the pneumatic assembly 12, thereby reducing the noise of the pneumatic assembly 12 during operation and improving the user experience.

[0193] In another example, a buffer 10f is disposed between the pneumatic assembly 12 and the first circuit board 10e, and also between the pneumatic assembly 12 and the cover portion 10b. By providing a buffer 10f between the pneumatic assembly 12 and the first circuit board 10e, and between the pneumatic assembly 12 and the cover portion, the buffer 10f can effectively buffer and dampen the pneumatic assembly 12. On the one hand, it can further reduce the impact of vibrations generated during the operation of the pneumatic assembly 12 on the electronic components on the first circuit board 10e, thereby improving the service life of the first circuit board 10e. On the other hand, it can reduce the noise during the operation of the pneumatic assembly 12, thus improving the user experience.

[0194] Optionally, the buffer 10f may include sound-absorbing cotton or silicone pads, etc., which can be selected according to the actual situation, and are not specifically limited in this embodiment.

[0195] Please see Figure 7 In some embodiments, the massage housing 110 is provided with a mounting surface 1100 and a first guide portion 1107. The massage waist support mechanism 1 also includes a lifting member 114, which is provided on the mounting surface 1100. The lifting member 114 is provided with a second guide portion 1140, which is slidably connected to the first guide portion 1107 along the width direction X. The airbag device 112 is configured to be inflatable to push the lifting member 114 along the width direction X. The massage head 111 is connected to the lifting member 114 to move relative to the massage housing 110 along the thickness direction Z under the push of the lifting member 114.

[0196] By configuring an airbag device 112 and a lifting component 114, when the airbag device 112 inflates, it can push the lifting component 114 to move in a first direction, causing the lifting component 114 to move the massage head 111 in the first direction, thereby raising the height of the massage head 111. When the airbag device 112 contracts, it can detach from the lifting component 114, allowing the lifting component 114 and the massage head 111 to move in the first direction, thereby lowering the height of the massage head 111. Therefore, when the user does not need to use the massage function of the massage module, the height of the massage head 111 can be lowered so that the massage head 111 does not press against the user's waist. At the same time, by adjusting the height of the massage head 111, the pressure of the massage head 111 can be adjusted, improving the flexibility of the massage module. For example, raising the height of the massage head 111 allows the user to feel a greater pressure, while lowering the height of the massage head 111 allows the user to feel a less pressure. Furthermore, by providing a second guide portion 1140 on the lifting component 114, the second guide portion 1140 can slide and cooperate with the first guide portion 1107 on the massage housing 110, making the movement of the lifting component 114 in the first direction more stable, thereby also making the movement of the massage head 111 in the first direction more stable, and preventing the movement direction of the massage head 111 from deviating during the process of raising and lowering the height.

[0197] Please refer to sections 7 through 8. Figure 10 , Figure 14 and Figure 15 In some embodiments, the first guide portion 1107 includes a fourth slide groove 1107a, which is disposed on the massage housing 110 and is arranged around the thickness direction Z. The second guide portion 1140 includes a plurality of guide posts 1140a, which are spaced apart around the thickness direction Z and are slidably connected to the fourth slide groove 1107a along the thickness direction Z.

[0198] In this way, by setting multiple guide posts 1140a spaced apart along the thickness direction Z, the guide posts 1140a can achieve a sliding engagement with the fourth slide groove 1107a along the thickness direction Z. Furthermore, the engagement of multiple guide posts 1140a with the fourth slide groove 1107a can effectively limit the position of the lifting component 114 in the plane containing the thickness direction Z and the third direction, making the movement of the lifting component 114 in the thickness direction Z more stable, thereby also making the movement of the massage head 111 in the thickness direction Z more stable. Simultaneously, by setting multiple guide posts 1140a, even if one or more guide posts 1140a are damaged, the lifting component 114 can still achieve a relatively stable sliding engagement with the fourth slide groove 1107a through the other guide posts 1140a, which can improve the service life of the massage assembly 11.

[0199] Optionally, the fourth slide groove 1107a is arranged around the thickness direction Z. It may include an annular groove arranged around the thickness direction Z, or it may include multiple grooves arranged around the thickness direction Z. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0200] For example, the number of guide posts 1140a can be two, three, four, five or six, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0201] Optionally, the guide post 1140a can be cylindrical, semi-cylindrical, or square, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0202] In some embodiments, the massage housing 110 has a first side 110d and a second side 110e that are opposite to each other along the thickness direction Z. The mounting surface 1100 is disposed on the first side 110d. The fourth sliding groove 1107a includes a first sub-groove 11070 and a plurality of second sub-grooves 11071. The first sub-groove 11070 is disposed on the first side 110d and is configured as an annular groove surrounding the thickness direction Z. The plurality of second sub-grooves 11071 are disposed on the bottom surface of the first sub-groove 11070 and are spaced apart along the thickness direction Z. The plurality of second sub-grooves 11071 extend through the second side 110e along the thickness direction Z.

[0203] In this way, on the one hand, since the second sub-slot 11071 is a through slot, multiple guide posts 1140a can be respectively inserted into multiple second sub-slots 11071 and slide with the second sub-slots 11071, which can increase the sliding stroke of the guide posts 1140a relative to the second sub-slots 11071 in the thickness direction Z, that is, increase the stroke of the massage head 111 in the thickness direction Z, without increasing the thickness of the massage housing 110. On the other hand, the first sub-slot 11070 can also achieve a certain sliding engagement with the lifting component 114, further improving the stability of the movement of the lifting component 114 in the thickness direction Z.

[0204] It is understandable that the second sub-slot 11071 is set in a one-to-one correspondence with the guide post 1140a. For example, when there are two guide posts 1140a, there are two second sub-slots 11071; when there are six guide posts 1140a, there are six second sub-slots 11071.

[0205] In some embodiments, the inner wall surface of the massage housing 110 is provided with a plurality of third protrusions 11000, which extend radially along the thickness direction Z, and each third protrusion 11000 is respectively disposed between two adjacent guide posts 1140a. In this embodiment, the inner wall surface of the first sub-groove 11070 is provided with a plurality of third protrusions 11000.

[0206] To facilitate sliding engagement with the second sub-groove 11071, the guide post 1140a typically protrudes from the lifting member 114 in a direction perpendicular to the thickness direction Z. By providing a third protrusion 11000 on the inner wall of the first sub-groove 11070, the third protrusion 11000 can achieve a certain sliding engagement with the lifting member 114, further improving the stability of the lifting member 114's movement in the thickness direction Z.

[0207] In some embodiments, the massage housing 110 has a protruding support portion 1108, which has a mounting surface 1100. The support portion 1108 is spaced apart from the inner wall surface of the massage housing 110 to form a fourth sliding groove 1107a. In this embodiment, the airbag device 112 is disposed on the support portion 1108, the lifting member 114 is disposed on the side of the airbag device 112 opposite to the support portion 1108, and the massage head 111 is connected to the side of the lifting member 114 opposite to the airbag device 112.

[0208] By providing a support portion 1108, the support portion 1108 can support the airbag device 112, and a first sub-groove 11070 of the fourth sliding groove 1107a can be formed between the support portion 1108 and the inner wall surface of the massage housing 110, which reduces the processing difficulty of the massage housing 110.

[0209] In some embodiments, the support portion 1108 is provided with a plurality of third engaging portions 11080 on the side facing the fourth slide groove 1107a. The plurality of third engaging portions 11080 are spaced apart circumferentially along the thickness direction Z. Each guide post 1140a is provided with a fourth engaging portion 11400. Each third engaging portion 11080 is engaged with each fourth engaging portion 11400 in a one-to-one circumferential manner along the thickness direction Z. One of the third engaging portion 11080 and the fourth engaging portion 11400 is a protrusion, and the other is a recess.

[0210] In this way, by providing multiple third engaging portions 11080 on the support portion 1108 and a fourth engaging portion 11400 on each guide post 1140a, the engaging cooperation between the third engaging portions 11080 and the fourth engaging portions 11400 can fix the lifting member 114 relative to the massage housing 110 in the rotation direction about the thickness direction Z, thereby preventing the lifting member 114 from rotating relative to the massage housing 110 when it moves along the thickness direction Z, and improving the stability of the lifting member 114 when it moves along the thickness direction Z.

[0211] Optionally, the shape of the protrusion can be a semi-cylinder, square column, or hemispherical shape, and the recess can be set to correspond to the shape of the protrusion. The specific shape can be selected according to the actual situation, and no specific limitation is made in this embodiment.

[0212] In some embodiments, the third engaging portion 11080 is a protrusion that extends along the thickness direction Z and protrudes from the top surface of the support portion 1108. The third engaging portion 11080 is also used to restrict the movement of the lifting member 114 in the thickness direction Z.

[0213] In this way, when the lifting member 114 moves toward the top surface of the support portion 1108 in the thickness direction Z, it will move to abut against the third engaging portion 11080. The third engaging portion 11080 can restrict the movement of the lifting member 114 in the thickness direction Z, and can protect the airbag device 112 between the support portion 1108 and the lifting member 114, preventing the airbag device 112 from being squeezed and damaged by the lifting member 114. At the same time, by making the third engaging portion 11080 extend along the thickness direction Z and protrude from the top surface of the support portion 1108, the third engaging portion 11080 can restrict the movement of the lifting member 114 in the thickness direction Z, realizing the structural reuse of the third engaging portion 11080 and simplifying the structure of the massage waist support mechanism 1.

[0214] In some embodiments, the massage housing 110 is provided with a first connecting hole 1109 disposed along the thickness direction Z, and the lifting member 114 is provided with a second connecting hole 1141 penetrating itself along the thickness direction Z, the second connecting hole 1141 communicating with the first connecting hole 1109, such as... Figure 7 As shown, the massage assembly 11 also includes a connecting post 116 and an elastic member 117. The connecting post 116 is slidably connected to the first connecting hole 1109 and the second connecting hole 1141, and one end of the connecting post 116 is connected to the massage head 111. One end of the elastic member 117 is connected to the massage housing 110, and the other end of the elastic member 117 is connected to the connecting post 116. The elastic member 117 is used to provide elastic restoring force for the connecting post 116 and the massage head 111.

[0215] In this way, the connecting post 116 can be set in the first connecting hole 1109 and pass through the second connecting hole 1141 of the lifting member 114 to connect with the massage head 111. The connecting post 116 can move with the massage head 111 in the thickness direction Z. When the airbag device 112 inflates, it can push the lifting member 114 to move in the thickness direction Z, so that the lifting member 114 drives the massage head 111 to move in the thickness direction Z, thereby raising the height of the massage head 111. This causes the connecting post 116 to move toward the massage head 111. At this time, the elastic member 117 is stretched. When the airbag device 112 contracts, it can disengage from the lifting member 114. At this time, the elastic member 117 contracts and provides elastic restoring force, causing the connecting post 116 to move away from the massage head 111. This causes the massage head 111 and the lifting member 114 to move in the thickness direction Z, thereby lowering the height of the massage head 111.

[0216] Optionally, the elastic element 117 can be a spring or a sheet, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0217] Please see Figure 7 In some embodiments, the massage component 11 further includes a light-emitting device 118, which is located on the side of the lifting member 114 opposite to the airbag device 112. The lifting member 114 is provided with a fastening member 1142 for fixing the light-emitting device 118. When the massage component 11 is applied to the massage lumbar support mechanism 1, since the massage component 11 is usually located inside the massage lumbar support mechanism 1, by providing the light-emitting device 118, the user can easily identify the position of the massage component 11 by the light emitted by the light-emitting device 118, thereby facilitating the adjustment of the position of the massage component 11 and improving the user experience.

[0218] Optionally, the light-emitting device 118 may include a second circuit board 1180 and one or more lamp beads 1181. The second circuit board 1180 can control the lamp beads 1181 to turn on or off. The lamp beads 1181 may be lamp beads 1181 or halogen lamp beads 1181, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0219] Optionally, the fastening component 1142 can be a hook or a buckle, and the number of fastening components 1142 can be one or more. The fastening component 1142 can be integrally formed with the lifting component 114, or it can be a separately set component. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment. In this embodiment, the fastening component 1142 is a hook, and the fastening component 1142 is used to fix the second circuit board 1180 of the light-emitting device 118.

[0220] Please see Figure 16In some embodiments, the airbag device 112 includes an airbag body 1120 and a ventilation port 1121 connected to the airbag body 1120. The mounting surface 1100 has a second groove 11001, the ventilation port 1121 is located in the second groove 11001, and the massage housing 110 has a third notch 1110 communicating with the second groove 11001. The third notch 1110 is used to avoid the ventilation port 1121. In this embodiment, the support portion 1108 has the second groove 11001, and the first housing 110a has the third notch 1110.

[0221] Thus, when the massage component 11 is applied to the massage lumbar support mechanism 1, the vent 1121 is used to communicate with the pneumatic component 12 of the massage component 11. The pneumatic component 12 can provide gas power to the airbag body 1120 through the vent 1121, thereby causing the airbag body 1120 to expand or contract. By providing a second groove 11001 on the mounting surface 1100, the second groove 11001 can accommodate the vent 1121. At the same time, by providing a third notch 1110 on the massage housing 110, the third notch 1110 can avoid the vent 1121, allowing the air tube 122 to pass through the notch to connect with the vent 1121 and the pneumatic component 12.

[0222] Please see Figure 17 The second aspect of this utility model also discloses a massage lumbar support 2, which includes the massage lumbar support 2 mechanism 1 as described in the first aspect of the above embodiment.

[0223] The massage lumbar support 2 provided in the second aspect of this utility model adopts the massage lumbar support mechanism 1 of the first aspect of this utility model. The massage component 11 is slidably disposed on the massage body along the width direction X, and a first adjustment component 13 is provided. The first adjustment component 13 provides power for the sliding of the massage component 11, thereby adjusting the position of the massage component 11 relative to the massage lumbar support mechanism 1 in the width direction X. When the user uses the massage function of the massage lumbar support mechanism 1, adjusting the position of the massage component 11 allows it to be aligned with the area the user needs to massage, improving the flexibility of the massage lumbar support mechanism 1. Furthermore, since the massage component 11, the mounting base 10, and the first adjustment component 13 are arranged in the thickness direction Z, the space in the thickness direction Z of the massage lumbar support mechanism 2 can be rationally utilized, reducing the size of the massage lumbar support mechanism 1 in the width direction X, making the structure of the massage lumbar support mechanism 1 more compact, thus facilitating the miniaturization design of the massage lumbar support 2.

[0224] In some embodiments, the massage lumbar support 2 further includes a housing 20, which covers the outer periphery of the massage lumbar support mechanism 1. The housing 20 serves to protect the massage lumbar support mechanism 1 and, at the same time, can cover some components of the massage lumbar support mechanism 1 (such as the first adjustment component 13), thereby improving the aesthetic appearance of the massage lumbar support 2.

[0225] Optionally, the material of the outer shell 20 may be leather, rubber, silicone or plastic, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0226] The massage lumbar support mechanism disclosed in the embodiments of this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the massage lumbar support mechanism and its core idea. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
