A car seat and its wear-resistant massage structure

Abstract

This application discloses a car seat and its wear-resistant massage structure, comprising a housing, a flexible cover over the housing, and a massage head disposed within the housing. The flexible cover includes: a cover body having a hollow area for the massage head to transmit massage movements; a wear-resistant ring located on the front side of the massage head, and its periphery being fixed to the cover body by a first stitch; an isolation layer is disposed between the wear-resistant ring and the massage head, the isolation layer being configured to cover the first stitch to prevent the massage head from abrading the first stitch. This invention, by configuring an isolation layer between the wear-resistant ring and the massage head, and by covering the first stitch, effectively prevents the massage head from directly abrading the first stitch during massage movements. Regardless of whether the first stitch is located on the inner periphery of the hollow area or on the outside and does not contact the massage head, the isolation layer provides additional protection, greatly reducing the risk of the first stitch breaking due to friction.

Description

Technical Field

[0001] This utility model relates to the technical field of wear-resistant massage structure cover device, and in particular to an automobile seat and its wear-resistant massage structure. Background Technology

[0002] As people's living standards improve, their pursuit of health and comfort is also increasing. Wear-resistant massage structures, as a type of health care device that can relieve physical fatigue, promote blood circulation, and relax muscles, have gained popularity among consumers. They are widely used in homes, offices, gyms, and other places, providing people with a convenient massage experience. In the structural design of wear-resistant massage structures, the flexible cover is a crucial component. It not only protects the massage head and internal structure but also comes into direct contact with the human body, affecting the comfort and effectiveness of the massage. Furthermore, to ensure the massage head can properly transmit massage movements, the flexible cover typically features perforated channels, allowing the massage head to freely extend and retract, transmitting the massage force to the skin.

[0003] In the prior art, such as the wear-resistant massage structure described in application number 2022233851211, the massage head is positioned and its relationship with the outer cover is such that the movable part is fixed to the cover body by stitching. However, in actual use, due to the lack of an insulating layer design as described in this application, the massage head may directly act on the first stitching connecting the cover body during massage. Prolonged friction and impact can cause premature wear and breakage of the first stitching, leading to the separation of the wear-resistant ring from the cover body, thus affecting the normal use of the wear-resistant massage structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a car seat and its wear-resistant massage structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wear-resistant massage structure includes a housing, a flexible cover over the housing, and a massage head disposed within the housing; the flexible cover includes: The main body of the cover has a hollowed-out area for the massage head to transmit massage movements; and A wear-resistant ring is located on the front side of the massage head, and its periphery is fixed to the cover body by a first stitch. An isolation layer is provided between the wear-resistant ring and the massage head, and the isolation layer is configured to cover the first stitch to prevent the massage head from abrading the first stitch during the massage action.

[0006] Furthermore, the first sewing thread is positioned on the inner periphery of the cutout area.

[0007] Furthermore, the area of ​​the isolation layer is larger than the area of ​​the hollowed-out area.

[0008] Furthermore, the insulating layer is attached to the cover body by a pull member.

[0009] Furthermore, the insulating layer is fixed to the cover body by a third sewing thread, and the third sewing thread is disposed outside the first sewing thread.

[0010] Furthermore, the insulating layer is composed of at least one of abrasion-resistant fabric, thickened polyester fabric, and bird's-eye fabric.

[0011] Furthermore, the insulating layer is bonded to the side of the wear-resistant ring near the massage head.

[0012] Furthermore, the cover body is made of composite sponge, and the wear-resistant ring is a composite material component.

[0013] Furthermore, the housing also includes a telescopic portion for the passage of the massage head, and the hollowed-out area is disposed at the end of the telescopic portion.

[0014] Furthermore, the massage heads are configured in multiple groups, which are spaced apart inside the housing, and the massage heads are configured to maintain contact with the insulating layer when performing a massage action.

[0015] Furthermore, the housing includes a mounting portion, to which the cover body is fixedly attached.

[0016] A car seat comprising the aforementioned wear-resistant massage structure.

[0017] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model features an insulating layer between the wear-resistant ring and the massage head, which covers the first stitching line, effectively preventing the massage head from directly abrading the first stitching line during massage. Regardless of whether the first stitching line is located on the inner or outer periphery of the hollowed-out area and does not contact the massage head, the insulating layer provides additional protection, significantly reducing the risk of the first stitching line breaking due to friction. This extends the service life of the flexible cover, and consequently, the service life of the entire wear-resistant massage structure, reducing the user's maintenance and operating costs.

[0018] 2. The isolation layer of this utility model is attached to the cover body by a pulling member or a third sewing thread. The method of attaching the isolation layer to the first sewing thread by the pulling member eliminates the need for additional sewing, simplifying the assembly process. At the same time, the pulling member can slightly adjust the position of the isolation layer according to the movement of the massage head to ensure continuous coverage of the sewing thread. The method of fixing the isolation layer to the cover body by the third sewing thread is more stable and can withstand long-term high-frequency massage movements, preventing the isolation layer from shifting or falling off and ensuring the durability of the protective effect. The two fixing methods can adapt to different usage scenarios and improve the flexibility of product design. Attached Figure Description

[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0033] Please see Figures 1-3This utility model discloses an automotive seat and a wear-resistant massage structure. The wear-resistant massage structure includes a housing 100, a flexible cover 200 covering the housing 100, and a massage head 500 disposed within the housing 100. The flexible cover 200 includes a cover body 210 and a wear-resistant ring 220. The periphery of the wear-resistant ring 220 is fixed to the cover body 210 by a first stitch 300. An isolation layer 400 is disposed between the wear-resistant ring 220 and the massage head 500. The isolation layer 400 can cover the first stitch 300 to prevent the massage head 500 from wearing down the first stitch 300 during massage. The housing 100, as the basic load-bearing structure of the wear-resistant massage structure, can be made of plastic or foam material. Due to the good plasticity of plastic material, it can be easily processed into various complex shapes through injection molding and other processes to meet the different structural design requirements of the wear-resistant massage structure housing, and it can provide a stable installation space for the internal massage head 500 assembly. The shell 100 has an overall arc shape to conform to the curves of the human back, waist, and other parts, facilitating massage operations by fitting the body closely. The shell 100 includes a telescopic part 110 and a mounting part 120. The telescopic part 110 is located in the central area of ​​the shell 100 and has multiple perforated channels 111 through which the massage heads 500 pass. The inner diameter of the perforated channels 111 is slightly larger than the outer diameter of the massage heads 500, ensuring that the massage heads 500 can freely extend and retract within the perforated channels 111. The mounting part 120 is used to accommodate the edge of the flexible cover 200, thereby achieving a fixed connection between the flexible cover 200 and the shell 100. The edge of the cover body 210 is installed on the shell as follows: the upper, left, and right sides are fixed to the shell via a strip 600 and a shaped metal wire passing through the strip 600; the bottom is bonded to the shell via an adhesive-backed fabric 700 to ensure a firm connection between the flexible cover 200 and the shell 100, preventing relative displacement during massage.

[0034] Please see Figures 4-7The flexible cover 200, as the part of the wear-resistant massage structure that comes into contact with the human body, directly affects the comfort and effectiveness of the massage. The flexible cover 200 includes a cover body 210 and a wear-resistant ring 220, which are fixed together by a first stitch 300 to form a complete flexible contact layer. The cover body 210 is made of composite sponge. It should be noted that the composite sponge in this application can use existing composite sponge materials, which will not be elaborated further here. The cover body 210 has multiple hollow areas 211, the number of which corresponds one-to-one with the number of massage heads 500. The hollow areas 211 are circular in shape, and their positions correspond to the telescopic portions 110 on the housing 100, ensuring that the massage heads 500 can pass through the hollow areas 211 and contact the human skin through the isolation layer 400 to transmit massage movements. The wear-resistant ring 220 is made of a composite material, which is composed of at least two of the following: wear-resistant cloth, thickened polyester cloth, nylon cloth, Poron, and bird's-eye cloth. The wear-resistant ring 220 is located on the front side of the massage head 500, and its size matches the diameter of the hollow area 211 to ensure that the wear-resistant ring 220 can completely cover the edge of the hollow area 211. In this embodiment, the wear-resistant ring 220 has two layers, including a surface layer 221 and an inner layer 222 composite with the surface layer. The surface layer 221 provides effective protection for the cover body 210, and the inner layer 222 is disposed between the surface layer 221 and the isolation layer 400. The periphery of the wear-resistant ring 220 is fixed to the cover body 210 by a first sewing thread 300. It should be noted that the first sewing thread 300 can be arranged in different ways according to different usage requirements. The first arrangement is that the first sewing thread 300 is disposed on the inner periphery of the hollow area 211. Figure 3As shown, the first stitch 300 is continuously sewn along the edge of the hollow area 211, forming a closed annular region. This arrangement tightly connects the edge of the wear-resistant ring 220 to the edge of the hollow area 211, effectively enhancing the structural strength of the edge of the hollow area 211 and preventing tearing of the cover body 210 when the massage head 500 moves. The second arrangement: the first stitch 300 is positioned outside the hollow area 211 and away from it, and is configured not to contact the massage head 500. The first stitch 300 also forms a closed annular region. This arrangement avoids direct contact between the first stitch 300 and the massage head 500, reducing wear on the first stitch 300 and extending the service life of the flexible cover 200. In this embodiment, the first stitch 300 forms an annular region, and the first stitch 300 is positioned along a direction that restricts radial elastic deformation of the moving part. Specifically, the first stitch 300 is stitched diagonally at a certain angle to the radial direction. This stitching method effectively disperses the radial force generated when the massage head 500 moves, limits the radial deformation of the moving part, and ensures the structural stability of the flexible cover 200. The insulating layer 400 is disposed between the abrasion-resistant ring 220 and the massage head 500. Its main function is to cover the first stitch 300, preventing the massage head 500 from abrading the first stitch 300 during massage. The insulating layer 400 can be composed of at least one of abrasion-resistant fabric, thickened polyester fabric, and bird's-eye fabric. In this embodiment, the insulating layer 400 is made of abrasion-resistant fabric, and the area of ​​the insulating layer 400 is larger than the area of ​​the perforated area 211. In this embodiment, the insulating layer 400 is circular in shape, completely covering the first stitch 300. Regardless of the angle at which the massage head 500 moves, it will not contact the first stitch 300, thus effectively protecting the first stitch 300. The insulating layer 400 is bonded to the side of the wear-resistant ring 220 near the massage head 500. This bonding method ensures a firm connection between the insulating layer 400 and the wear-resistant ring 220 while preventing excessive adhesive overflow that could affect massage comfort. To further enhance the fixation of the insulating layer 400, it is adhered to the wear-resistant ring 220 with adhesive to prevent it from peeling or detaching during use. Please refer to [link / reference]. Figure 10 In one embodiment of this application, the insulating layer 400 is attached to the cover body 210 by a pulling member. Specifically, the outer edge of the insulating layer 400 is fixed to the first sewing line 300 by a pulling member. In this embodiment, the pulling member is a pull strap 800, which is bonded to the outer edge of the insulating layer 400 and configured to restrict the inner abrasion-resistant fabric to be pulled only within the width of the pull strap. Furthermore, the outer edge of the pull strap 800 is further fixed to the insulating layer 400 by a second sewing line 900. Please refer to [link to relevant documentation]. Figure 11In another embodiment of this application, the isolation layer 400 is fixed to the cover body 210 by a third sewing thread 910. Specifically, the third sewing thread 910 is disposed outside the first sewing thread 300. The isolation layer can only be pulled within the range of the third sewing thread 910 and its outer edge, which can avoid excessive pulling that may cause the edge part of the isolation layer to delaminate.

[0035] The fixed massage head 500 is disposed inside the housing 100 and is the core component for realizing the massage function. Multiple sets of massage heads 500 are provided; in this embodiment, four sets of massage heads 500 are arranged in a matrix, capable of fully covering the back, waist, and other parts of the human body, achieving all-around massage. It should be noted that the structure of the massage head 500 in this application is the same as that in application number 202222126756.3, and will not be described in detail here. The massage head 500 is configured to maintain contact with the insulating layer 400 during massage. Specifically, the massage head 500 has a telescopic stroke such that when the massage head 500 is in its maximum extended position, the massage ball can closely adhere to the insulating layer 400, transmitting the massage force to the human skin through the insulating layer 400.

[0036] When the wear-resistant massage structure is in operation, the motor drives the massage head 500 to reciprocate and extend. The massage ball remains in contact with the insulating layer 400 during movement, transmitting massage force to the skin through the insulating layer 400 to achieve the massage function. Because the insulating layer 400 covers the first stitch 300, the massage head 500 does not directly contact the first stitch 300 during movement, effectively preventing wear on the first stitch 300. Simultaneously, both the wear-resistant ring 220 and the insulating layer 400 are made of wear-resistant materials, resisting long-term friction of the massage head 500 and extending the service life of the flexible cover 200. The cover body 210 is made of composite sponge material, possessing good elasticity and cushioning properties, providing comfortable support for the body during massage. The design of the mounting part 120 ensures the connection between the flexible cover 200 and the housing 100, preventing relative displacement during massage. The design of the telescopic part 110 provides sufficient space for the movement of the massage head 500, ensuring that the massage head 500 can freely extend and retract, achieving effective massage.

[0037] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
