[0029] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Reference below Figures 1-4 A waist support assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0031] like Figures 1-4 As shown, the lumbar support assembly 100 according to the first embodiment of the present invention includes: a shell 1, a massage element, an outer frame 2 and an adjustment assembly 3.

[0032] Specifically, the housing 1 forms a receiving cavity, the massage element is connected to the housing 1 and is located within the receiving cavity, the outer frame 2 is connected to the housing 1, and the outer frame 2 and the housing 1 are movable relative to each other, and the adjustment assembly 3 is connected between the housing 1 and the outer frame 2 to adjust the relative position of the outer frame 2 and the housing 1. It can be understood that the massage element is installed in the lumbar support, and the protrusion volume of the massage element is adjusted by the adjustment assembly 3. The outer frame 2 is movable relative to the housing 1. When the outer frame 2 moves backward relative to the housing 1, the massage element is more exposed. When the outer frame 2 moves forward relative to the housing 1, the massage element is less exposed, thereby adjusting the contact area between the massage element and the human body to meet the needs of the user.

[0033] According to the lumbar support assembly 100 of the embodiment of the present invention, by setting an adjustment assembly 3 between the shell 1 and the outer frame 2, the relative position between the shell 1 and the outer frame 2 is adjusted, thereby adjusting the exposed volume of the massage part, so that the user can adjust the position or shape of the lumbar support according to their needs, which can better adapt to the needs of different body shapes or postures and meet the massage experience of different users.

[0034] In some embodiments of the present invention, Figure 3 As shown, the adjustment assembly 3 includes: an adjustment rod 31 and an adjustment seat 32. The adjustment rod 31 is rotatably connected to the housing 1. One end of the adjustment rod 31 is located within the accommodating cavity, and the other end of the adjustment rod 31 is located outside the accommodating cavity. A first adjustment portion is formed on the adjustment rod 31. The adjustment seat 32 is fixedly connected to the outer frame 2. A second adjustment portion is formed on the adjustment seat 32. The first adjustment portion and the second adjustment portion cooperate to adjust the relative position of the outer frame 2 and the housing 1. It can be understood that when the adjustment rod 31 rotates, the position of the outer frame 2 relative to the housing 1 can be changed through the interaction between the first adjustment portion and the second adjustment portion. In this way, the user can easily adjust the angle or shape of the lumbar support by simply rotating the adjustment rod 31, thereby better adapting to the body shape needs of different users or providing personalized support and massage effects.

[0035] Furthermore, the first adjustment portion is formed as a latching tooth 312, and the second adjustment portion is formed as a latching slot 321. The latching teeth 312 include multiple latching teeth 312 arranged along the circumference of the adjustment rod 31, and the latching slot 321 includes multiple latching teeth 312 arranged along the front-to-back direction of the adjustment seat 32. The latching teeth 312 extend into the latching slot 321. When the position of the lumbar support needs to be adjusted, the user can rotate the adjustment rod 31 to select the appropriate latching teeth 312 to align with the latching slot 321. Once the appropriate position is selected, the latching teeth 312 will be embedded in the corresponding latching slot 321, thereby locking the position of the outer frame 2 relative to the housing 1. The user can adjust the outer frame 2 to the most suitable position according to their own comfort requirements, and the position will be firmly maintained. This allows the user to finely control the angle and support strength of the lumbar support, ensuring stability after adjustment. Even during use, it will not easily loosen, ensuring safety and reliability.

[0036] In other embodiments, Figure 4 As shown, an assembly portion 313 is formed on the adjustment rod 31, and a gear 311 is provided at the position of the assembly portion 313. The gear 311 cooperates with multiple slots 321. The user adjusts the appropriate teeth 312 to align with the slots 321 by rotating the adjustment rod 31. The user adjusts the outer frame 2 to the most suitable position according to his or her own comfort requirements.

[0037] In some embodiments of the present invention, the housing 1 is formed with a recess 11, and the outer frame 2 is formed with a protrusion 21, which is movably disposed in the recess 11 in the front-to-back direction. As a result, the tight fit between the recess 11 and the protrusion 21 provides a smooth movement path, ensuring the stability and support of the structure. The recess 11 limits the range of motion of the protrusion 21, increasing the stability and durability of the entire structure.

[0038] In some embodiments of the present invention, Figure 4 As shown, a groove 111 is formed at the top of the recessed portion 11. The top wall of the protruding portion 21 cooperates with the groove 111 to define an installation space. The adjustment seat 32 is disposed within the installation space, and the latching teeth 312 are located within the installation space. It is understood that when the user rotates the adjustment lever 31, the latching teeth 312 on the adjustment lever 31 will move within the latching groove 321 of the adjustment seat 32, thereby driving the outer frame 2 to slide in the front-to-back direction. Because the adjustment seat 32 is firmly mounted in the space defined by the groove 111 and the top wall of the protruding portion 21, the entire adjustment process is very stable and will not become loose or misaligned.

[0039] In some embodiments of the present invention, the outer frame 2 is formed with a first guide portion, and the housing 1 is formed with a second guide portion. The outer frame 2 and the housing 1 cooperate with each other to allow for relative movement in the front-to-back direction. It will be appreciated that when the outer frame 2 needs to move back and forth relative to the housing 1, the first guide portion slides along the second guide portion, ensuring that the outer frame 2 can only move in the predetermined direction, preventing unnecessary lateral displacement or rotation, and improving the stability and durability of the entire assembly.

[0040] Furthermore, if Figure 4 As shown, one of the first and second guide portions is formed into a guide groove 12, and the other of the first and second guide portions is formed into a guide protrusion 22. The guide protrusion 22 is movable along the length of the guide groove 12. Therefore, when the user needs to adjust the position of the lumbar support, the guide protrusion 22 slides within the guide groove 12, thereby driving the outer frame 2 to move in the front-to-back direction. Because the guide groove 12 limits the movement path of the guide protrusion 22, the outer frame 2 can only move in the predetermined direction, preventing unnecessary lateral displacement or rotation, improving user comfort, and enhancing the overall performance of the product.

[0041] In some embodiments of the present invention, the adjustment assembly 3 further includes a pressure plate 33. The pressure plate 33 and the housing 1 define a mounting channel. The adjustment rod 31 is rotatably disposed within the mounting channel and is movable along the axis of the mounting channel. Thus, the pressure plate 33 provides additional support and stability, preventing the adjustment rod 31 from unnecessary displacement or deformation during use.

[0042] Furthermore, the inner circumferential wall of the mounting channel is formed with a positioning rib, and the outer circumferential wall of the adjustment rod 31 is formed with a positioning groove 314. There are multiple positioning grooves 314 arranged along the circumference of the adjustment rod 31. The positioning ribs are located within the positioning grooves 314 to limit the rotation of the adjustment rod 31. It can be understood that whenever the positioning rib fully enters a positioning groove 314, the adjustment rod 31 is locked in this position, preventing it from rotating freely. This locking function improves the rotation accuracy and stability of the adjustment rod 31 and enhances the functionality and durability of the entire lumbar support assembly 100.

[0043] Optionally, the adjusting rod 31 is a nylon part or an aluminum alloy part, the pressing piece 33 is a nylon part, the locking tooth 312 is a POM part or an aluminum alloy part, the outer frame 2 is a nylon part, the shell 1 is a nylon part or an aluminum alloy part, and the adjusting seat 32 is a nylon part or an aluminum alloy part.
