Description

Technical Field

[0001] This utility model relates to the field of chairs, and in particular to a connecting structure and a seat. Background Technology

[0002] Seating is an indispensable facility in modern life and work, and its comfort largely depends on the structure and performance of the seat cushion. Common seat cushions typically consist of a seat board made of hard materials (such as plastic, wood, or metal) and a seat cushion covered with a flexible material (such as polyurethane foam, memory foam, or textile fibers). The seat board primarily provides support and structural strength, while the seat cushion comes into direct contact with the body, providing a soft touch and pressure distribution to enhance comfort.

[0003] Due to the significant differences in physical properties between the seat foam and the seat plate—the former being soft and easily deformable, while the latter being rigid and fixed in shape—how to efficiently, reliably, and aesthetically fix the two together has always been an important technical problem in this field.

[0004] Existing methods of fixing are generally as follows:

[0005] Adhesive fixing: The seat foam is glued to the seat plate using glue or double-sided tape. This method has obvious drawbacks: the adhesive is prone to aging and failure, especially in environments with large temperature fluctuations, which may cause the seat foam to shift or fall off; in addition, the use of adhesive does not meet environmental protection requirements, and once bonded, subsequent maintenance and replacement are extremely inconvenient.

[0006] Mechanical fastener fixing: Screws, nail guns, etc., are driven directly into the seat plate from the surface of the seat foam for fixing. Although this method provides a secure connection, it damages the integrity of the seat foam surface, affecting aesthetics, and the nail heads may gradually protrude during use, affecting seating comfort. More importantly, the flexible seat foam needs to be pressed and positioned during assembly. Uneven pressure can easily cause the seat foam to slide or twist on the smooth, hard seat plate, resulting in inaccurate assembly position, requiring repeated adjustments, and severely reducing production efficiency.

[0007] In summary, existing connection technologies are insufficient to resolve the fundamental contradictions arising from differences in material properties: ensuring a firm and stable connection between the flexible seat foam and the rigid seat plate while simultaneously meeting the demands of modern production for efficient assembly, easy operation, and convenient maintenance. Utility Model Content

[0008] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a connection structure that can ensure a firm and stable connection between the flexible connecting cotton and the rigid connecting plate, while also meeting the modern production requirements of efficient assembly, simple operation, and easy maintenance.

[0009] This utility model also proposes a seat having the above-mentioned connection structure.

[0010] On one hand, the connection structure according to the embodiment of this utility model includes:

[0011] Connecting plate;

[0012] Connecting cotton is provided on the connecting plate;

[0013] The connecting plate and the connecting cotton each have a buckle on one side and a slot on the other side. The buckle and the slot can cooperate to install the connecting cotton on the connecting plate. Part of the structure of the buckle or the slot is embedded in the connecting cotton.

[0014] According to some embodiments of the present invention, the buckle sequentially includes an embedding part, an extension part, and a snap-fit ​​part. The embedding part is embedded in the connecting cotton, a portion of the extension part is embedded in the connecting cotton, and another portion extends into the slot. The snap-fit ​​part can snap into the slot.

[0015] According to some embodiments of this utility model, the buckle and the slot are provided in multiple sets, the buckle and the slot are arranged in a one-to-one correspondence, and the buckles and slots in different sets are staggered.

[0016] According to some embodiments of the present invention, the buckle is provided with a connecting hole, and the buckle is installed on the connecting cotton through the connecting hole.

[0017] According to some embodiments of the present invention, the buckle is provided on a plurality of hooks and a plurality of connecting holes, and the arrangement direction of the plurality of hooks is perpendicular to the arrangement direction of the plurality of connecting holes.

[0018] According to some embodiments of the present invention, the connecting plate is provided with a stepped groove on its periphery, and the connecting cotton is disposed in the stepped groove.

[0019] According to some embodiments of the present invention, the connecting plate has a concave surface in the middle and the connecting cotton has a convex surface, the convex surface being able to cooperate with the concave surface.

[0020] According to some embodiments of the present invention, it also includes a mesh fabric that wraps around the connecting plate and the connecting cotton.

[0040] Reference Figures 1-4 The basic embodiment of the first aspect of this utility model provides a connection structure, including:

[0041] Connecting plate 100;

[0042] Connecting cotton 200 is installed on connecting plate 100;

[0043] In the connecting plate 100 and the connecting cotton 200, one of them is provided with a buckle 210 and the other is provided with a slot 110. The buckle 210 and the slot 110 can cooperate to allow the connecting cotton 200 to be installed on the connecting plate 100. Part of the structure of the buckle 210 or the slot 110 is embedded in the connecting cotton 200.

[0044] According to embodiments of this utility model, this configuration achieves at least the following effects: The connection between the connecting cotton 200 and the connecting plate 100 is achieved through the cooperation of the buckle 210 and the slot 110. The connecting cotton 200 is made of flexible material, while the connecting plate 100 is made of rigid material. The buckle 210 or the slot 110 can be pre-embedded in the connecting cotton 200 or the connecting plate 100. This snap-fit ​​structure not only enables rapid positioning and stable installation of the connecting cotton 200 on the connecting plate 100, effectively avoiding misalignment and repeated adjustments caused by slippage of the connecting cotton 200 during traditional assembly, but also significantly improves assembly efficiency and consistency. Simultaneously, it greatly reduces the skill requirements of operators and minimizes installation deviations or deformation of the connecting cotton 200 that may be caused by uneven force applied manually, making it particularly suitable for automated or large-scale production scenarios. This structure also greatly facilitates subsequent product maintenance. When the connecting cotton 200 needs cleaning or replacement, it can be easily separated by simply detaching the clip 210 without damaging the original structure, significantly improving the product's maintainability and lifespan. The clip 210 or slot 110 structure, embedded within the connecting cotton 200, effectively increases the contact area between the clip 210 or slot 110 and the connecting cotton 200, allowing for a more stable installation. This enhances adhesion stability and peel resistance, ensuring that the clip 210 or slot 110 remains secure during repeated disassembly and reassembly.

[0045] It should be noted that the connecting plate 100 and the connecting cotton 200 can be structures such as seat cushions, backrests, armrests, lumbar supports, or headrests on the seat, which can support the weight of various parts of the human body such as the buttocks, head, or waist, so as to make people feel comfortable.

[0046] It should be noted that the connecting cotton 200 is a flexible material, and the connection between the buckle 210 or the slot 110 and the connecting cotton 200 includes, but is not limited to, adhesive bonding, sewing or mechanical anchoring, taking into account both process feasibility and connection reliability.

[0047] In some embodiments, in a first embodiment of the buckle 210, the buckle 210 sequentially includes an embedding portion 211, an extension portion 212, and a locking portion 213. The embedding portion 211 is embedded within the connecting cotton 200. A portion of the extension portion 212 is embedded within the connecting cotton 200, while another portion extends into the slot 110. The locking portion 213 can lock into the slot 110. When the buckle 210 locks into the slot 110, the extension portion 212 can be slightly deformed under external force, allowing the locking portion 213 to pass through the slot 110. After passing through the slot 110, the extension portion 212 returns to its original shape, and the locking portion 213 can lock into the slot 110. The embedding portion 211 is embedded inside the connecting cotton 200; the extension portion 212 is partially located within the connecting cotton 200 and partially extends into the slot 110; the locking portion 213 achieves the locking function with the slot 110. This segmented structure optimizes stress distribution and improves durability while ensuring connection strength.

[0048] Furthermore, the snap-fit ​​portion 213 is provided with a guide surface, which can abut against the inner wall of the snap-fit ​​groove 110, which is beneficial to the deformation of the extension portion 212.

[0049] In some embodiments, in a second embodiment of the buckle 210, the buckle 210 sequentially includes an embedded part, an insertion part, and an elastic part. The embedded part is embedded inside the connecting cotton 200; the insertion part is partially located inside the connecting cotton 200 and partially extends into the slot 110; the elastic part can elastically deform and can be set as a spherical, elliptical, or other geometric shape that can achieve elastic snap-fit. Its diameter is larger than the inner diameter of the slot 110. When passing through the slot 110, it shrinks and deforms, and after passing through, it returns to its original shape, so that the buckle 210 and the slot 110 can snap together.

[0050] In some embodiments, multiple sets of latches 210 and slots 110 are provided, with each set corresponding to the other, and different sets of latches 210 and slots 110 are staggered. It is understood that there is a positional deviation in the vertical, horizontal, or front-back directions between each set of latches 210 and slots 110, and the latches 210 are installed in slots 110 located at different spatial positions (determined by the longitudinal, lateral, and vertical spacing). This multi-point, non-collinear installation method ensures that the constraint forces generated by each latch 210 mutually support and balance each other in space, effectively preventing the latches 210 from loosening, twisting, or slipping relative to the connecting plate 100, greatly improving the stability and deformation resistance of the installation. The engagement method between the latches 210 and slots 110 is intuitive and straightforward, and easy to operate. Simultaneously, the longitudinal, lateral, and vertical spacing settings also implicitly provide precise positioning references, helping to ensure the consistency of the installation position.

[0051] It should be noted that misalignment refers to the misalignment of mechanical parts or mechanisms in spatial position, that is, there is a gap in the longitudinal, lateral and vertical positions, forming a certain positional deviation. The "longitudinal", "lateral" and "vertical" gaps all refer to the spatial relationship relative to the horizontal installation reference plane.

[0052] In some embodiments, a stepped groove 120 is provided on the periphery of the connecting plate 100, and the connecting cotton 200 is disposed in the stepped groove 120. The stepped groove 120 facilitates the assembly of the connecting plate 100 and the connecting cotton 200. When assembling the connecting plate 100 and the connecting cotton 200, they can be assembled according to the position of the stepped groove 120, without needing to align the positions of the buckle 210 and the slot 110. Once the positions of the stepped groove 120 are aligned, the positions of the buckle and the slot also align. By pressing the positions of the buckle 210 and the slot 110, the connecting cotton 200 can be installed on the connecting plate 100.

[0053] In some embodiments, the buckle 210 is provided with a connecting hole 214, through which the buckle 210 is mounted on the connecting cotton 200. Additional connectors can be used to further secure the buckle to the connecting cotton 200, enhancing the redundancy and reliability of the connection. These additional connectors can be, for example, sewing threads.

[0054] Furthermore, the buckle 210 can also be made using a sponge foaming process. The principle is that by injecting an expandable solution, the solution will expand on its own, filling any gaps, and the sponges will be connected together through the connecting holes.

[0055] In some embodiments, the snap fastener is provided on a plurality of hooks and a plurality of connecting holes 214, the arrangement direction of the plurality of hooks being perpendicular to the arrangement direction of the plurality of connecting holes 214. The hooks are the aforementioned extension 212 and snap-fit ​​portion 213, which can be used to connect with the slot, and the connecting holes are used to install on the connecting cotton. The two are arranged in different directions and have different force directions, so the snap fastener is not easy to detach from the connecting cotton during disassembly, thus improving the stability of installation.

[0056] In some embodiments, the connecting cotton 200 is made of a flexible material, and the connecting plate is made of a rigid material. The flexible design effectively improves user comfort, while the rigid connecting plate provides support for the user.

[0057] In some embodiments, the connecting plate 100 has a concave surface 220 in its center, and the connecting cotton 200 has a convex surface that can mate with the concave surface 220. The connecting cotton 200 is disposed on the concave surface 220 and is made of a flexible material. The mating design with the concave surface 220 helps to increase the thickness of the connecting cotton 200, making it more comfortable for the user. This design increases the effective thickness of the connecting cotton 200 within a limited space, improving support comfort, while also helping to maintain the stability of the connecting cotton 200's shape and prevent displacement during use. The mating structure of the concave and convex surfaces also increases the contact area between the connecting plate 100 and the connecting cotton 200.

[0058] In some embodiments, the system further includes a mesh fabric that wraps around the connecting plate 100 and the connecting cotton 200. The mesh fabric structure wraps around the connecting plate 100 and the connecting cotton 200, preventing the connection points of the connecting plate 100 and the connecting cotton 200 from being directly exposed. This provides overall coverage, enhances the appearance, and provides protection, preventing the internal structure from being exposed and improving the overall quality and safety of the product.

[0059] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0060] Although some embodiments of the present utility model have been shown and described in this specification, the present utility model should not be limited to the above embodiments. As long as they achieve the technical effects of the present utility model by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles disclosed in the present utility model, without departing from the principles and purpose of the present utility model, should be included within the scope of protection disclosed in the present utility model and should be considered to fall within the protection scope of the present utility model.
