When the user uses the massage function of the massage lumbar support mechanism, adjusting the position of the massage component allows the massage head to be aligned with the area the user wants to massage. Simultaneously, the pneumatic component controls the expansion of the airbag device. When the airbag device expands, it pushes the massage head to move in the thickness direction, raising the height of the massage head. Conversely, the pneumatic component controls the contraction of the airbag device. When the airbag device contracts, it allows the massage head to move in the width direction, lowering the height of the massage head. Therefore, when the user uses the massage function of the massage lumbar support mechanism, adjusting the height of the massage head allows for adjustment of the pressure applied by the massage head, improving the flexibility of the massage lumbar support mechanism. For example, raising the massage head height allows the user to feel a greater pressure, while lowering the massage head height allows the user to feel a less intense pressure. The invention utilizes a massage lumbar support mechanism that allows for both width-direction and thickness-direction adjustment of the massage head's position, enhancing the flexibility of the massage lumbar support mechanism. Users can adjust the massage head according to their needs, thus improving the user experience. Attached Figure Description

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0060] Please refer to the following: Figures 1 to 4 This invention provides a massage assembly 11, which includes a mounting base 10, a massage assembly 11, and a pneumatic assembly 12. The massage assembly 11 is movably connected to the mounting base 10 and can move relative to the mounting base 10 along the width direction X. The massage assembly 11 includes a massage housing 110, a massage head 111, and an airbag device 112. The airbag device 112 is disposed between the massage head 111 and the massage housing 110. The massage head 111 is configured to move closer to or further away from the massage housing 110 along the thickness direction Y under the action of the airbag device 112. The pneumatic assembly 12 is pneumatically connected to the airbag device 112. The width direction X intersects with the thickness direction Y.

[0061] It is understandable that the aforementioned width direction X can be the left and right direction of the massage waist support mechanism 1, that is, the left and right direction corresponding to the user when using the massage waist support mechanism 1.

[0062] The thickness direction Y mentioned above is the direction that intersects with the width direction X. That is, the thickness direction Y and the width direction X are not parallel. The thickness direction Y can be the front and back direction of the massage waist support mechanism 1. In this case, the thickness direction Y is perpendicular or approximately perpendicular to the width direction X (approximately perpendicular means that the angle between the thickness direction Y and the width direction X is close to 90°, such as 88° or 89°, etc. Since it is difficult to ensure that the components are completely perpendicular in actual products, a certain error can be accepted).

[0063] That is, when the massage head 111 is close to the massage housing 110 in the thickness direction Y, the height of the massage head 111 increases, and the massage head 111 moves away from the user's massage area. When the massage head 111 moves away from the massage housing 110 in the thickness direction Y, the height of the massage head 111 decreases, and the massage head 111 moves closer to the user's massage area. The above directions are examples provided to facilitate understanding of the structure and function of the massage waist support mechanism 1 of the present invention, and do not limit the scope of this application.

[0064] The massage component 11 provided in this embodiment of the invention is movably connected to the mounting base plate 10 along the width direction X. This allows adjustment of the position of the massage component 11 relative to the mounting base plate 10 in the width direction X. When a user uses the massage function of the lumbar massage mechanism 1, adjusting the position of the massage component 11 allows the massage head 111 to be aligned with the area the user wants to massage. Simultaneously, the pneumatic component 12 can control the expansion of the airbag device 112. When the airbag device 112 expands, it pushes the massage head 111 to move in the thickness direction Y, thus raising the height of the massage head 111. Conversely, the pneumatic component 12 can control the contraction of the airbag device 112. When the airbag device 112 contracts, it allows the massage head 111 to move in the width direction X, thus lowering the height of the massage head 111. 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, thus improving the flexibility of the lumbar massage mechanism 1. For example, raising the height of the massage head 111 will result in a greater pressure felt by the user, while lowering the height of the massage head 111 will result in a less intense pressure felt by the user. The invented lumbar massage mechanism 1 simultaneously achieves position adjustment of the massage head 111 in the width direction X and height adjustment of the massage head 111 in the thickness direction Y, improving the flexibility of the lumbar massage mechanism 1. Users can adjust the massage head 111 according to their needs, enhancing the user experience.

[0065] 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 first 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.

[0066] 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 movably 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] In some embodiments, the pneumatic component 12 is disposed on the mounting base plate 10 and spaced apart from the massage component 11. Since the massage component 11 can move relative to the mounting base plate 10 in the width direction X, by spaced apart from the massage component 11, the pneumatic component 12 can avoid the massage component 11, reducing the occurrence of the pneumatic component 12 obstructing the movement of the massage component 11.

[0071] In some embodiments, the massage housing 110 and the pneumatic assembly 12 are spaced apart and disposed on the same side of the mounting base 10. Since the pneumatic assembly 12 and the airbag device 112 are usually connected by an air tube 122 so that the pneumatic assembly 12 can provide power to the airbag device 112 through the air tube 122, placing the massage housing 110 and the pneumatic assembly 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 assembly 12 and the airbag device 112.

[0072] In other embodiments, the massage housing 110 and the pneumatic assembly 12 may be located on different sides of the mounting base plate 10.

[0073] In this application, the mounting base plate 10 is a structure used to support components such as the massage component 11 and the pneumatic component 12. The mounting base plate 10 can be a plate-shaped structure, a block-shaped structure, or a frame structure, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made.

[0074] In some embodiments, the mounting substrate 10 includes a main body 10a and a cover 10b. The cover 10b is disposed on the main body 10a and near the upper side 102 to form a receiving cavity 108 with at least a portion of the main body 10a. The pneumatic assembly 12 is disposed within the receiving cavity 108. The cover 10b is provided with clearance holes 109 (e.g., ...). Figure 5 As shown, the air pipe 122 of the pneumatic assembly 12 is connected to the airbag device 112 and the pneumatic assembly 12 through the clearance hole 109.

[0075] 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 second 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 first adjustment assembly 113, further reducing the influence between the pneumatic assembly 12 and the first 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.

[0076] 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.

[0077] Optionally, the main body 10a and the cover 10b can be plate-like structures, block-like structures, or frame structures, etc., and can be selected according to the actual situation. In this embodiment, no specific limitation is made. In this embodiment, both the main body 10a and the cover 10b can be plate-like structures, so that the size of the massage waist support core 1 in the thickness direction Y is small, that is, the massage waist support core 1 is relatively thin and light.

[0078] In some embodiments, the massage assembly 11 further includes a first adjustment assembly 113, which is disposed in the massage housing 110 and is connected to the massage head 111 in a transmission manner.

[0079] In this way, the first adjustment component 113 can drive the massage head 111 to rotate around the thickness direction Y, providing power for the rotation of the massage head 111, thereby realizing the kneading function of the massage head 111.

[0080] It is understood that the massage housing 110 and the pneumatic assembly 12 are spaced apart and disposed on the same side of the mounting base 10. Since the first adjustment assembly 113 is disposed in the massage housing 110, the first adjustment assembly 113 and the pneumatic assembly 12 are also spaced apart and disposed on the same side of the mounting base 10. Because the first adjustment assembly 113 and the pneumatic assembly 12 are prone to vibration during operation, by spaced apart the pneumatic assembly 12 and the first adjustment assembly 113, the influence between the pneumatic assembly 12 and the first adjustment assembly 113 can be reduced, thereby improving the service life of the pneumatic assembly 12 and the first adjustment assembly 113.

[0081] In some embodiments, the airbag device 112 and the first adjustment component 113 are arranged along the height direction Z in the massage housing 110, and the pneumatic component 12 and the first adjustment component 113 are spaced apart along the height direction Z.

[0082] It is understandable that the height direction Z mentioned above is the direction that intersects with both the width direction X and the thickness direction Y. That is, the height direction Z is not parallel to the width direction X and the thickness direction Y. The height direction Z can be the up and down direction of the massage waist support mechanism 1, that is, the height direction corresponding to the user when the massage waist support mechanism 1 is in use. At this time, the height direction Z is perpendicular or approximately perpendicular to the width direction X and the thickness direction Y.

[0083] By arranging the airbag device 112 and the pneumatic component 12 in the height direction Z along with the first adjustment component 113, on the one hand, a certain distance can be maintained between the first adjustment component 113 and the pneumatic component 12 in the height direction Z, thereby reducing the influence between the pneumatic component 12 and the first adjustment component 113 and improving their service life. On the other hand, it can reduce the space occupied by the first adjustment component 113 and the airbag device 12 in the height direction Z of the massage lumbar support core 1, thereby reducing the size of the massage lumbar support core 1 in the height direction Z, thus expanding the application scenarios of the massage lumbar support core 1. For example, it can be easily 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.

[0084] In some embodiments, the mounting base plate 10 has an upper side 102 and a lower side 103 that are opposite to each other in the height direction Z, the pneumatic assembly 12 and the airbag device 112 are disposed near the upper side 102, and the first adjustment assembly 113 is disposed at least partially near the lower side 103.

[0085] In this way, while ensuring a certain distance between the first adjustment component 113 and the pneumatic component 12 in the height direction Z, on the one hand, since the first adjustment component 113 is usually relatively heavy, placing 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, 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 Y, the massage head 111 is also placed 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 Z, which is beneficial for the massage head 111 to massage the user's waist.

[0086] In some embodiments, the massage housing 110 includes a first housing 110a and a second housing 110b connected to each other to form a mounting cavity 110c. A first adjustment component 113 is disposed in the mounting cavity 110c. The first housing 110a has a mounting surface 1100 on the side opposite to the second housing 110b, and an airbag device 112 is disposed on the mounting surface 1100.

[0087] In this way, by configuring the massage housing 110 as a first housing 110a and a second housing 110b, it is convenient to install the components into the mounting cavity 110c formed between the first housing 110a and the second housing 110b. The first adjustment component 113 is disposed within the first housing 110a and the second housing 110b, which not only protects the first adjustment component 113 but also isolates it from other components (such as the airbag device 112), reducing the impact of vibrations generated by the first adjustment component 113 during operation on other components. By providing a mounting surface 1100 on the first housing 110a, the mounting surface 1100 can support the airbag device 112.

[0088] Please refer to the following: Figure 4 and Figure 6In some embodiments, the first housing 110a includes a first part 1101 and a second part 1102. The mounting surface 1100 is disposed on the side of the first part 1101 opposite to the second housing 110b. The mounting cavity 110c includes a first chamber 1105 and a second chamber 1106 spaced apart. The first part 1101 and the second part 1102 are respectively enclosed by the second housing 110b to form the first chamber 1105 and the second chamber 1106. The first adjustment component 113 includes a first motor 113a and a first transmission mechanism 113b. The first motor 113a is connected to the first transmission mechanism 113b. The first transmission mechanism 113b is connected to the massage head 111. The motor is configured to drive the transmission mechanism to move. The first transmission mechanism 113b is disposed in the first chamber 1105, and the first motor 113a is disposed in the second chamber 1106.

[0089] Thus, the first part 1101 and the second part 1102 of the first housing 110a respectively enclose the second housing 110b to form the first chamber 1105 and the second chamber 1106. On the one hand, they can respectively accommodate the first transmission mechanism 113b and the first motor 113a. On the other hand, the first chamber 1105 and the second chamber 1106 are arranged in the height direction Z, which allows the first motor 113a to be placed in the second chamber 1106 near the lower side 103 of the mounting base plate 10. Since the weight of the first 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.

[0090] Optionally, the first motor 113a can 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.

[0091] In some embodiments, the massage lumbar support mechanism 1 further includes a second adjustment component 13, which is disposed on the mounting base plate 10 and connected to the massage housing 110. The second adjustment component 13 is configured to drive the massage housing 110 to move relative to the mounting base plate 10 in the width direction X. By providing the second adjustment component 13, power can be provided for the movement of the massage housing 110 relative to the mounting base plate 10 in the width direction X, facilitating the adjustment of the position of the massage housing 110.

[0092] In some embodiments, the mounting substrate 10 has a front side 100 and a rear side 101 that are opposite to each other in the thickness direction Y, the massage component 11 is located on the front side 100, and the second adjustment component 13 is located on the rear side 101. In this embodiment, the main body 10a of the mounting substrate 10 has a front side 100 and a rear side 101.

[0093] In this way, on the one hand, the space of the mounting base plate 10 in the thickness direction Y can be rationally utilized, reducing the space of the massage lumbar support core 1 in the width direction X that the massage component 11 and the second adjustment component 13 need to occupy. This helps to reduce the size of the massage lumbar support core 1 in the width direction X, making it easier to place the massage lumbar support core 1 on a sofa or chair. On the other hand, it allows the pneumatic component 12, the first adjustment component 113, and the second adjustment component 13 to be spaced apart from each other, reducing the mutual influence between the pneumatic component 12, the first adjustment component 113, and the second adjustment component 13, and improving the service life of the pneumatic component 12, the first adjustment component 113, and the second adjustment component 13.

[0094] 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.

[0095] 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.

[0096] In some embodiments, the massage lumbar support mechanism 1 includes two massage components 11, which are spaced apart along the width direction X. A second adjustment component 13 is configured to drive the two massage components 11 to slide along the width direction X, so that the two massage components 11 move closer to each other or further away from each other.

[0097] The second adjustment component 13 allows the two massage components 11 to be moved closer or further apart. 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.

[0098] 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 Z, and the two first sliding grooves 105 are at least partially staggered in the width direction X. The two massage components 11 are respectively slidably connected to the two first sliding grooves 105.

[0099] By setting two first sliding grooves 105, the two massage components 11 can slide relative to the two first sliding grooves 105. Moreover, the two first sliding grooves 105 are spaced apart along the height direction Z, which can make reasonable use of the space of the mounting base plate 10 in the height direction Z and reduce the space required by the two first sliding grooves 105 in the width direction X. This helps to reduce the size of the massage lumbar support core 1 in the width direction X, making it easier to place the massage lumbar support core 1 on a sofa or chair.

[0100] Optionally, the second adjustment component 13 may include a motor, a gear and rack 131b, or a linear motor, etc. The specific selection can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0101] Please see Figure 7 In some embodiments, the second adjustment component 13 includes a second motor 130 and a second transmission mechanism 131 disposed on the rear side 101. The second transmission mechanism 131 includes a gear structure 131a and two racks 131b. The two racks 131b are respectively disposed in two first slide grooves 105 and are respectively connected to the corresponding massage components 11. The gear structure 131a is meshed between the two racks 131b and is connected to the second motor 130. The second motor 130 is configured to drive the gear structure 131a to rotate so that the two racks 131b slide in opposite or opposite directions in the corresponding first slide grooves 105.

[0102] In this way, the second 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 second 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.

[0103] Optionally, the second 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.

[0104] Optionally, the gear structure 131a may include one or more gears, which may be selected according to the specific circumstances, and is not specifically limited in this embodiment. When the gear structure 131a has multiple gears, such as two, three, four or five gears, the second motor 130 can be decelerated through the cooperation of multiple gears.

[0105] In some embodiments, the rear side 101 is provided with two second sliding grooves 107, which are respectively connected to two first sliding grooves 105. The two second sliding grooves 107 are at least partially staggered in the width direction X, and the two racks 131b are slidably connected to the two second sliding grooves 107. By providing two second sliding grooves 107, the two second sliding grooves 107 can respectively accommodate two racks 131b, and the two racks 131b can slide relative to the two second sliding grooves 107 in the width direction X. Since the racks 131b themselves have a certain length, the length of the second sliding 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 sliding grooves 107 are at least partially staggered in the width direction X. This can reduce the space occupied by the two second sliding grooves 10 on the mounting base plate 10 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.

[0106] In some embodiments, both massage components 11 are provided with a first protrusion 1150 protruding towards the first groove 105 (e.g., Figure 3 As shown, the two first protrusions 1150 are slidably connected to the two first slide grooves 105 and are respectively connected to the two racks 131b. In this embodiment, the second housing 110b of the massage housing 110 is provided with the first protrusions 1150 protruding towards the first slide grooves 105.

[0107] 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.

[0108] In some embodiments, the second motor 130 is positioned near the lower side 103, and the gear structure 131a and the two racks 131b are positioned relative to the second motor 130 near the upper side 102.

[0109] Since the second 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, preventing it from becoming top-heavy and making it difficult to place on a sofa or chair. Simultaneously, positioning the gear structure 131a and two racks 131b relative to the second motor 130 near the upper side 102 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 Z-direction of height, facilitating connection with the massage housing 110.

[0110] In some embodiments, the axial direction of the shaft of the second motor 130 is parallel to the width direction X, and the second transmission mechanism 131 further includes a worm 131c, one end of which is connected to the shaft of the second motor 130, and the other end of which is meshed with the gear structure 131a.

[0111] Since rack 131b moves along the width direction X, the gear in gear structure 131a needs to rotate around the thickness direction Y. Typically, the axial direction of the shaft of the second motor 130 needs to be parallel to the thickness direction Y. By setting a worm gear 131c, which can transmit power between two intersecting shafts, the axial direction of the shaft of the second motor 130 can be set parallel to the width direction X, and it can also drive the gear in gear structure 131a to rotate around the thickness direction Y. By setting the axial direction of the shaft of the second motor 130 parallel to the width direction X, i.e., the second motor 130 is placed parallel to the width direction X, the space required for the second motor 130 in the thickness direction Y can be reduced, which helps to reduce the size of the massage lumbar support mechanism 1 in the thickness direction Y.

[0112] Please see Figures 8 to 11In some embodiments, the massage housing 110 is further provided with a first guide portion 1107, and the massage assembly 11 further includes a lifting member 114. The lifting member 114 is provided on the mounting surface 1100 and is provided with a second guide portion 1140. The second guide portion 1140 is slidably connected to the first guide portion 1107 along the thickness direction Y. The massage head 111 is connected to the side of the lifting member 114 away from the airbag device 112. The lifting member 114 is configured to move relative to the massage housing 110 along the thickness direction Y when the airbag device 112 is inflated, so as to push the massage head 111 to move along the thickness direction Y.

[0113] Thus, by providing the lifting component 114, when the airbag device inflates, it can push the lifting component 114 to move along the thickness direction Y, causing the lifting component 114 to drive the massage head 111 to move along the thickness direction Y, thereby raising the height of the massage head 111. When the airbag device contracts, it can detach from the lifting component 114, allowing the lifting component 114 and the massage head 111 to move along the thickness direction Y, thereby lowering the height of the massage head 111. Furthermore, by providing a second guide portion 1140 on the lifting component 114, which can slide and engage with the first guide portion 1107 on the massage housing 110, the movement of the lifting component 114 in the width direction X is more stable, thereby also making the movement of the massage head 111 in the width direction X more stable, preventing the movement direction of the massage head 111 from deviating during the process of raising and lowering the height.

[0114] Optionally, one of the two first guide portions 1107 can be a slider or a slide rod, and the other can be a groove or a sliding hole. The specific selection can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0115] In some embodiments, the first guide portion 1107 includes a third slide groove 1107a, which is disposed in the massage housing 110 and is arranged around the thickness direction Y. The second guide portion 1140 includes a plurality of guide posts 1140a, which are spaced apart around the thickness direction Y and are slidably connected to the third slide groove 1107a along the thickness direction Y. In this embodiment, the third slide groove 1107a is disposed in the first housing 110a.

[0116] In this way, by setting multiple guide posts 1140a spaced apart along the thickness direction Y, the guide posts 1140a can achieve a sliding engagement with the third slide groove 1107a along the thickness direction Y. Furthermore, the engagement of multiple guide posts 1140a with the third slide groove 1107a can effectively limit the position of the lifting component 114 in the plane containing the width direction X and the height direction Z, making the movement of the lifting component 114 in the width direction X more stable, thereby also making the movement of the massage head 111 in the width direction X 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 third slide groove 1107a through the other guide posts 1140a, which can improve the service life of the massage assembly 11.

[0117] Optionally, the third groove 1107a is arranged around the thickness direction Y. It may include an annular groove arranged around the thickness direction Y, or it may include multiple grooves arranged around the thickness direction Y. The specific choice can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0118] 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.

[0119] 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.

[0120] In some embodiments, the massage housing 110 has a first side 110d and a second side 110e opposite to each other along the thickness direction Y. A mounting surface 1100 is disposed on the first side 110d. The third 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 configured as an annular groove surrounding the thickness direction Y. The plurality of second sub-grooves 11071 are spaced apart on the bottom surface of the first sub-groove 11070 and extend along the thickness direction Y to the second side 110e. In this embodiment, the first housing 110a has a first side 110d and a second side 110e.

[0121] 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 Y, that is, increase the stroke of the massage head 111 in the thickness direction Y, without increasing the thickness of the first housing 110a. On the other hand, the first sub-slot 11070 can also achieve a certain sliding engagement with the lifting member 114, further improving the stability of the movement of the lifting member 114 in the width direction X.

[0122] 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.

[0123] 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 third groove 1107a. By providing the support portion 1108, the support portion 1108 can support the airbag device 112, and a first sub-groove 11070 of the third groove 1107a can be formed between the support portion 1108 and the inner wall surface of the mounting surface 1100, reducing the processing difficulty of the first housing 110a.

[0124] In some embodiments, the support portion 1108 is provided with a plurality of first engaging portions 11080 on the side facing the third slide groove 1107a. The plurality of first engaging portions 11080 are spaced apart circumferentially along the thickness direction Y. Each guide post 1140a is provided with a second engaging portion 11400. Each first engaging portion 11080 is engaged with each second engaging portion 11400 in a one-to-one circumferential manner along the thickness direction Y. One of the first engaging portion 11080 and the second engaging portion 11400 is a protrusion, and the other is a recess.

[0125] In this way, by providing multiple first engaging portions 11080 on the support portion 1108 and second engaging portions 11400 on each guide post 1140a, the engaging cooperation between the first engaging portions 11080 and the second engaging portions 11400 can fix the lifting member 114 relative to the massage housing 110 in the rotational direction about the thickness direction Y, thereby preventing the lifting member 114 from rotating relative to the massage housing 110 when it moves along the thickness direction Y, and improving the stability of the lifting member 114 when it moves along the thickness direction Y.

[0126] 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.

[0127] In some embodiments, when the first engaging portion 11080 is a protrusion, the first engaging portion 11080 extends along the width direction X and protrudes from the top surface of the support portion 1108. The first engaging portion 11080 is also used to restrict the movement of the lifting member 114 in the thickness direction Y. It can be understood that the top surface of the support portion 1108 is the side of the support portion 1108 that faces away from the second housing 110b.

[0128] In this way, when the lifting member 114 moves toward the top surface of the support portion 1108 in the thickness direction Y, it will move to abut against the first engaging portion 11080. The first engaging portion 11080 can restrict the movement of the lifting member 114 in the thickness direction Y, 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 first engaging portion 11080 extend in the width direction X and protrude from the top surface of the support portion 1108, the first engaging portion 11080 can restrict the movement of the lifting member 114 in the thickness direction Y, realizing the structural reuse of the first engaging portion 11080 and simplifying the structure of the massage waist support mechanism 1.

[0129] Please see Figure 12 The second aspect of the present invention also discloses a massage lumbar support 2, which includes a massage lumbar support mechanism 1 as described in the first aspect of the above embodiments.

[0130] The massage lumbar support 2 provided in the second aspect of the present invention uses the massage lumbar support mechanism 1 of the first aspect of the present invention. By making the massage component 11 movably connected to the mounting base plate 10 along the width direction X, the position of the massage component 11 relative to the mounting base plate 10 in the width direction X can be adjusted. When the user uses the massage function of the massage lumbar support mechanism 1, by adjusting the position of the massage component 11, the massage head 111 of the massage component 11 can be aligned with the area to be massaged by the user. At the same time, the pneumatic component 12 can control the airbag device 112 to inflate. When the airbag device 112 inflates, it can push the massage head 111 to move in the thickness direction Y, thereby raising the height of the massage head 111. The pneumatic component 12 can also control the airbag device 112 to contract. When the airbag device 112 contracts, it can move the massage head 111 in the width direction X, thereby lowering the height of the massage head 111. Therefore, when using the massage function of the massage lumbar support mechanism 1, the user can adjust the pressure of the massage head 111 by adjusting its height, thus improving the flexibility of the massage lumbar support mechanism 1. For example, raising the height of the massage head 111 will result in a greater pressure felt by the user, while lowering the height of the massage head 111 will result in a less intense pressure felt by the user. The massage lumbar support 2 of the invention simultaneously achieves position adjustment of the massage head 111 in the width direction X and height adjustment of the massage head 111 in the thickness direction Y, improving the flexibility of the massage lumbar support 2. Users can adjust the massage head 111 according to their needs, enhancing the user experience.

[0131] 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.

[0132] 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.

[0133] The massage lumbar support mechanism and massage lumbar support disclosed in the embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the massage lumbar support mechanism and massage lumbar support of the present invention and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
