Description

Technical Field

[0001] This utility model relates to the field of seat accessories technology, and in particular to a massage module structure that prevents interference from flexible filling materials. Background Technology

[0002] As people's demands for quality of life increase, seat accessories such as headrests, lumbar supports, and footrests are becoming increasingly popular. To enhance seating comfort, these accessories often incorporate massage mechanisms to provide therapeutic functions. However, a significant technical defect exists in actual use: when a user leans against these accessories, changes in body pressure distribution and posture adjustments cause the flexible material inside the accessories to easily infiltrate the working area of ​​the massage mechanism. Furthermore, multiple experiments have demonstrated that the flexible material inside the accessories mostly infiltrates the working area of ​​the massage mechanism from both sides. This phenomenon leads to unintended entanglement between the moving parts of the massage mechanism, such as the massage heads and transmission mechanisms, and the flexible material during operation, causing a "cotton roll" malfunction. This problem not only causes the mechanism to jam and experience abnormal wear but also significantly shortens the product's lifespan.

[0003] In existing technologies, to mitigate the risk of flexible material intrusion, some solutions employ a design strategy of increasing the volume of the movement module, creating physical isolation by increasing the safety distance between the movement's outer shell and the flexible material. However, this approach has significant drawbacks: 1. Large movement modules significantly increase the overall thickness and weight of the components, resulting in bulky and cumbersome products; 2. Large-sized movements require more materials and more complex structures, significantly increasing production costs; 3. Excessively large internal modules compress design space, limiting the product's curved surface design; 4. Thicker and larger components are difficult to match with different seat models, reducing versatility.

[0004] Therefore, there is an urgent need for a new structural solution that can break through the limitations of existing technologies on product lightweighting, thinning, and design freedom while ensuring reliable isolation between the internal flexible materials and the movement, thereby balancing functional reliability and user experience. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a massage module structure that prevents interference from flexible filling materials. This structure effectively prevents the flexible filling materials inside the seat accessories from being rolled into the massage mechanism, while also avoiding a significant increase in the size and weight of the mechanism module.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A massage module structure for preventing interference from flexible fillers includes a flexible filler and a massage mechanism. The flexible filler has a mounting groove for accommodating the massage mechanism. An elastic isolation baffle is provided on the inner wall of the mounting groove, forming an isolation barrier between the massage mechanism and the flexible filler. The elastic modulus of the elastic isolation baffle is greater than that of the flexible filler, and the elastic isolation baffle deforms and elastically returns to its original position along with the flexible filler.

[0008] Furthermore, the bottom wall of the mounting groove is provided with a positioning groove for mounting the massage mechanism.

[0009] Furthermore, the elastic isolation baffle can be any one of a continuous annular structure, a discontinuous annular structure, or a non-annular structure.

[0010] Furthermore, a pre-drilled groove for the elastic isolation baffle is provided at the edge of the mounting groove for the elastic isolation baffle to be fitted and embedded.

[0011] Furthermore, a notch is provided on the elastic isolation baffle for the outer casing of the massage mechanism to be inserted.

[0012] Furthermore, the material used to manufacture the elastic isolation baffle includes, but is not limited to, any one of PP, PE, TPE, TPU, and EVA.

[0013] Furthermore, the elastic isolation baffle and the flexible filler are fixed together by integral foaming or adhesive bonding.

[0014] Furthermore, the cross-section of the elastic isolation baffle is multi-folded, including a first covering surface, a second covering surface, and a third covering surface. The first covering surface is used to cover the surface of the flexible filler at the edge of the mounting groove, the second covering surface is used to cover the side wall of the mounting groove, and the third covering surface extends to cover the bottom surface of the mounting groove.

[0015] Furthermore, the elastic isolation baffle is fixed to the outer shell of the massage mechanism by screws.

[0016] Furthermore, the flexible filler includes, but is not limited to, any one of polyurethane foam, memory foam, or silicone foam.

[0017] The present invention has the following beneficial effects: By structurally adding an elastic isolation baffle, the flexible filling material is separated from the working area of ​​the massage mechanism, effectively preventing cotton roll-up; the elastic isolation baffle has a plate-like structure, which is suitable for various compact massage devices; the elastic isolation baffle can be installed by integral foaming or bonding, which is simple in process and has good stability.
