[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0033] The seat cushions in the prior art are generally directly set on the surface of the seat. Although the direct fixing method is simple, the seat cushions need to be cleaned and replaced after sitting for a long time, which requires destroying the fixing settings of the seat itself, or using additional seat covers as a means of routine maintenance and cleaning. However, the seat covers themselves, whether they are uniformly configured by the seat merchant or purchased from outside, will affect the appearance and coordination of the seat itself. Moreover, the seat covers of a single set are prone to displacement or even slipping. Although the sewing method has a good fixing effect, it is not conducive to disassembly, cleaning and replacement.

[0034] In view of this, the utility model provides a seat structure, which can be fixed by the mutual interference extrusion of the accommodating cavity 2011 and the fixing strip 3 after the seat cushion is wrapped on the seat surface through the cooperation of the accommodating cavity formed on the convex part of the first surface of the seat and the fixing strip fixed on the seat cushion. On the one hand, it can ensure the relative fixation between the seat cushion and the seat, and it is not easy to shift or slip, and the fixing effect is good. At the same time, when disassembly is needed, the seat cushion 1 can be disassembled by simply taking out the fixing strip from the accommodating cavity 2011 of the convex part 201, which is convenient for cleaning and replacement.

[0035] Depend on Figures 1 to 4It can be seen that a seat structure in the present case includes a support portion 2, a first surface of the support portion is provided with a convex portion 201, one end of the convex portion 201 is open, so that a accommodating cavity 201 connected to the outside is formed in the convex portion, and also includes: a seat cushion 1, a main body 101 of the seat cushion 1 is mounted and attached to the second surface of the support portion 2, and an edge 102 of the seat cushion is tightened along the second surface of the support portion 2 toward the first surface, so that the edge 102 of the seat cushion is bent and enters the accommodating cavity 2011 of the convex portion 201, and the main body 101 of the seat cushion, the edge 102 of the seat cushion and the edge of the edge 102 of the seat cushion cooperate to enter the accommodating cavity 2011 to form a triangular structure.

[0036] It should be further pointed out that the first surface of the support portion 2 is the surface of the seat part facing the ground when the seat is in normal use, and the second surface of the support portion 1 is the surface supporting the hips and legs in a sitting position. The cross-section of the convex portion 201 of the first surface is a semi-closed annular cross-section or a semi-closed frame cross-section, so that the surface of the accommodating cavity 2011 after the fixing strip 3 with a circular or square cross-section is inserted into the accommodating cavity 2011 of the convex portion 201 is completely fitted with the surface of the fixing strip 3 and pressed against each other, the contact surface area is increased, and the relative friction force is increased, so that the relative movement tendency of the fixing strip 3 relative to the accommodating cavity 2011 of the convex portion 2 is reduced, thereby reducing the possibility of the edge 102 of the seat cushion 1 slipping.

[0037] The seat structure in this embodiment is intended to improve the aesthetics and structural stability of the chair, and the structural improvement is achieved by the close combination of the protrusion 201 and the seat cushion 1. This structure not only enhances the relative stability and durability of the support portion 2 of the seat and the seat cushion 1, but also simplifies the assembly process of the seat cushion 1.

[0038] The first surface is designed with a convex portion 201. The convex portion 201 plays a key role in functionality. One end of the convex portion 201 is open, forming a receiving cavity 2011 directly connected to the external environment, providing a precise guide for the subsequent installation of the seat cushion 1; the seat cushion 1 is made of high-quality fabric material, aiming to provide softness and comfort while ensuring wear resistance and breathability. The main body 101 of the seat cushion 1 is completely fitted and tightly attached to the second surface of the support portion 2 to ensure that there is no looseness or wrinkles, thereby enhancing the visual flatness. The edge 102 of the seat cushion naturally transitions along the second surface of the support portion, then turns to the first surface and smoothly enters the receiving cavity 2011 of the convex portion 201. This edge finishing step not only requires precise sewing technology, but also requires the seat cushion material to have good elasticity and recovery to ensure that it can maintain a tight appearance after repeated use.

[0039] When the edge 102 of the seat cushion is completely embedded in the accommodating cavity 2011, it not only fixes the seat cushion to prevent sliding, but also forms a stable triangular structure, thereby enhancing the stability of the edge of the seat and reducing wear and tear that may be caused by friction or heavy pressure during daily use.

[0040] In summary, the seat structure in this embodiment achieves a dual improvement in stability and comfort through the cooperation between the support part 2 and the seat cushion 1.

[0041] It should be further pointed out that the edge 102 of the seat cushion is sewn or glued with a fixing strip 3, which extends from the open end of the protrusion 201 into the interior of the accommodating cavity 201. When the fixing strip 3 is installed in place, the edge 102 of the seat cushion is in a taut state on both sides with the open end of the protrusion 201 as the fulcrum.

[0042] Preferably, both sides of the main body 101 of the seat cushion 1 are in a tensioned state with the edge of the supporting part 2 as a fulcrum.

[0043] The support part 2 of the seat structure is made of high-quality materials, preferably materials to ensure sufficient strength and durability. The common support part 2 of the seat is made of plastic or wood but is not limited to one or more of the above. Specifically:

[0044] 1. Plastic material: Plastic seats are the most common type on the market. They are durable, easy to clean and colorful. They can also ensure that users maintain a certain degree of stability when sitting in a poor posture. Plastic seats also have a certain degree of elasticity, which can relieve the pressure on the hips and legs caused by sitting for a long time.

[0045] 2. Wood material: The wooden seat is stable and solid, and has beautiful texture.

[0046] 3. Mesh material: The mesh seat is made of breathable mesh material. The seat made of this material has excellent ventilation performance, can effectively disperse pressure and reduce the discomfort of sitting for a long time. It is suitable for use in warm seasons or air-conditioned rooms.

[0047] 4. Leather material: Made of artificial leather or genuine leather, the leather surface is smooth and easy to clean.

[0048] Preferably, a lining 4 is provided on one side of the main body 101 of the seat cushion 1 in contact with the second surface of the support portion 2. It should be further pointed out that the lining 4 is preferably made of sponge, silicone or other materials having other characteristics such as heat preservation, breathability and cooling.

[0049] It should be further pointed out that the opposite side surface of the accommodating cavity 2011 of the protrusion 201 is an elastic surface or a hard surface.

[0050] It should be further pointed out that the fixing strip and the side wall of the accommodating cavity 2011 are mutually interference squeezed.

[0051] It should be further pointed out that the cross section of the fixing bar is circular or square; the fixing bar is arranged in sections and at intervals or in a closed loop.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
