[0046] Embodiment one

[0047] In view of the defects of the prior art, the present applicant, based on years of rich practical experience and professional knowledge in the field of design and manufacture, and with the use of theory, actively researches and innovates, in order to create a technology that can solve the defects in the prior art. After continuous research, design, and repeated trial of samples and improvement, the present utility model is finally created, which has practical value.

[0048] Please refer to Figures 1-5 The embodiment of the present utility model provides a net frame body, comprising an outer frame 1, an inner frame 2 and a net cloth 3; in this design, the functions and layout of each component are carefully considered to achieve the best overall performance and user experience.

[0049] Specifically, the inner frame 2 is arranged in the inner space of the outer frame 1, and the relative position and size between the two are accurately calculated to ensure the stability and functionality of the structure. Notably, there is a gap between the four peripheral edges of the inner frame 2 and the four peripheral edges of the outer frame 1 to cleverly form the clamping groove 4. This clamping groove 4 provides reliable support and positioning for the installation of the mesh cloth 3.

[0050] The mesh cloth 3, as an important part of the mesh frame structure, has its four peripheral edges cleverly clamped in the clamping groove 4. This design not only ensures that the mesh cloth 3 can tightly fit between the inner and outer frames, effectively improving the overall stability of the structure, but also provides users with a more comfortable and safe riding experience.

[0051] In summary, the mesh frame structure provided by the embodiments of the present application, through its unique inner and outer frame design and clamping groove setting, not only realizes the optimization of the structure and the improvement of the performance, but also provides a new idea and solution for the manufacturing of furniture products such as seats.

[0052] It is particularly emphasized that one of the biggest highlights of the mesh frame design in the present embodiment is the split design of the outer frame 1 and the inner frame 2. This innovative design not only reduces the manufacturing difficulty and improves the production efficiency, but also gives the outer frame 1 and the inner frame 2 high flexibility and replaceability, meaning that in actual application, users or manufacturers can easily replace any one of the frames according to specific needs or maintenance needs.

[0053] This feature not only greatly simplifies the maintenance process and reduces maintenance costs, but also provides users with unprecedented personalized customization space. Specifically, by combining different outer frames 1 with different inner frames 2, users can easily adjust the size of the clamping groove 4 to adapt to mesh cloths 3 of different specifications or thicknesses, thereby meeting diverse use needs.

[0054] In addition, another significant advantage of the split design is that it makes the manufacturing and processing of the frame more flexible and efficient. Manufacturers can quickly adjust their production strategies according to market demand or order requirements, produce different specifications of outer frames 1 and inner frames 2 separately, and then form mesh frame structures that meet different needs through simple assembly.

[0055] In summary, the mesh frame design in the embodiments of the present application, through its unique split design, not only improves the flexibility and maintainability of the structure, but also provides users with more diverse and personalized use options, while also bringing great convenience and efficiency improvement to manufacturers' production and processing.

[0056] Please refer to Figure 3 again, and in combination with Figures 4-5In one embodiment of the present embodiment, an innovative design detail is proposed, namely the card slot 4 is not simply parallel to the edge of the outer frame 1, but is ingeniously inclined towards the center direction of the outer frame 1 (i.e. Figure 3 the direction of the CL dotted line of the outer frame 1).

[0057] More specifically, the card slot 4 is not only inclined towards the center direction of the outer frame 1, but also further inclined towards the bottom direction of the outer frame 1. This inclined design brings many advantages in practical application.

[0058] Firstly, the inclined design towards the center direction helps to enhance the contact area and friction between the mesh cloth 3 and the card slot 4, thereby ensuring that the mesh cloth 3 can remain stable after installation and is not prone to displacement or falling off. Secondly, the inclined design towards the bottom direction helps to guide the mesh cloth 3 to naturally sag and fit between the inner and outer frames during installation, further improving the overall stability of the structure.

[0059] In addition, the inclined card slot 4 also provides users with a more convenient installation experience. During installation, the user only needs to gently push the edges of the mesh cloth 3 along the inclined direction of the card slot 4, and the installation can be easily completed without the need for additional fixing tools or complex operation steps.

[0060] In summary, the card slot 4 design in the present embodiment, through its unique double-inclined setting, not only improves the stability and aesthetics of the structure, but also provides users with a more convenient and efficient installation experience. This innovative design undoubtedly provides new ideas and directions for the optimization and upgrading of the net frame structure.

[0061] In the detailed description of the present embodiment, another key component of the net frame structure is further disclosed, namely the card strip 5. The design intention of the card strip 5 is to ensure that the mesh cloth 3 can be stably and accurately clamped in the card slot 4, thereby further improving the stability and durability of the entire net frame structure.

[0062] Regarding the fixed connection method between the mesh cloth 3 and the card strip 5, the present embodiment provides multiple possible implementation paths to meet different application scenarios and individual needs. Next, two typical implementation ways will be analyzed in detail to better understand the ingenuity of this design.

[0063] Firstly, in the first implementation way, a direct fixed connection relationship is established between the edges of the mesh cloth 3 and the card strip 5. As shown in Figure 6As shown, this connection can be achieved by needle sewing, i.e., using professional sewing equipment to tightly sew the edge of the mesh cloth 3 with the card strip 5; at the same time, the method of adhesion can also be selected, and the two are firmly adhered together by using high-strength adhesive. No matter which way is adopted, it can ensure that the connection between the mesh cloth 3 and the card strip 5 is both stable and durable.

[0064] Next, in the second embodiment, the four edges of the mesh cloth 3 are ingeniously provided with a hem, and the card strip 5 is ingeniously arranged inside the hem. Specifically, the hem can also be formed by needle sewing or adhesion to tightly combine with the edge of the mesh cloth 3, and the formed hem is an edge protection structure that is both beautiful and practical. The card strip 5 is inside the hem and in close contact and fixed with the hem itself, so as to ensure that the mesh cloth 3 can be stably clamped in the card slot 4.

[0065] In summary, the present embodiment introduces the key component of the card strip 5 and provides multiple flexible fixing connection methods, which not only further improves the stability and durability of the mesh frame structure, but also provides more diversified and personalized selection space for users.

[0066] Please carefully review again Figure 2 in order to deeply understand one specific embodiment of the connection method of the outer frame 1 and the inner frame 2 in the present embodiment. Here, the present embodiment elaborates two feasible fixing connection schemes, aiming to ensure the structural stability between the outer frame 1 and the inner frame 2, while taking into account the convenience and flexibility of installation.

[0067] First, the first fixing connection scheme, i.e., fixed connection by screws. In this scheme, corresponding screw holes or threaded columns are pre-set on the outer frame 1 and the inner frame 2, and by selecting screws of appropriate specifications and lengths, the two are tightly connected together. The advantage of screw fixing connection is that it has a stable structure and can withstand large external force and torque, ensuring the safety and stability of the mesh frame during use. At the same time, screw connection is also convenient for disassembly and reinstallation, providing great convenience for later maintenance and replacement.

[0068] Next, the second fixing connection scheme, i.e., fixed connection by buckle structure. In this scheme, the edges of the outer frame 1 and the inner frame 2 are designed into a buckle shape that matches each other, and the fixed connection of the two can be achieved by a simple buckling action. The advantage of the buckle structure fixed connection is that the installation process is simple and fast, without the need for additional tools or materials, greatly reducing the installation cost and time cost. At the same time, the buckle connection also has a certain elasticity, which can adapt to a certain degree of deformation and displacement, thereby improving the overall adaptability and durability of the mesh frame.

[0069] In summary, the present embodiment provides two solutions, screw fixation and buckle structure fixation, to meet different application scenarios and personalized needs. Both solutions have high structural stability and installation convenience, providing strong support for the optimization and upgrading of the mesh body structure.

[0070] In a carefully designed embodiment of the present embodiment, the connection stability between the card strip 5 and the card slot 4 is further enhanced by introducing an innovative barb structure, achieving a tight wedge between the two.

[0071] Specifically, a first barb is ingeniously arranged on the surface of the card strip 5 in contact with the wall of the card slot 4. This design not only increases the contact area between the card strip 5 and the wall of the card slot 4, but also effectively enhances the friction between the two through the shape characteristics of the barb, thereby enhancing the stability of the connection.

[0072] At the same time, the wall of the card slot 4 is also correspondingly provided with a second barb. This design allows the first barb to smoothly meet and wedge with the second barb when the card strip 5 is inserted into the card slot 4. This wedge effect not only further consolidates the connection between the card strip 5 and the card slot 4, but also makes the connection between the two more secure and stable, so that they are not easily loosened or detached even under external force.

[0073] It is worth mentioning that the wedge design of the first barb and the second barb also has a certain self-locking function. This means that once the card strip 5 is successfully inserted and wedged in the card slot 4, they will remain in a tight connection state unless sufficient reverse force is applied. This self-locking function not only improves the reliability of the connection, but also provides users with a more convenient and safe use experience.

[0074] In summary, the present embodiment successfully enhances the connection stability between the card strip 5 and the card slot 4 by introducing the wedge design of the first barb and the second barb.

[0075] In an embodiment of the present embodiment, the design of the card slot 4 is ingeniously adjusted to ensure that the combination of the mesh cloth 3 and the card strip 5 can be stably and tightly clamped in the card slot 4. Specifically, the present embodiment specially sets the width of the card slot 4 to be less than the sum of the thickness of the mesh cloth 3 and the card strip 5.

[0076] The starting point of this design idea is to achieve the close fitting of the mesh cloth 3 and the clamping strip 5 in the clamping groove 4 by utilizing the elasticity of the material itself and the special structure of the clamping strip 5. When the combination of the mesh cloth 3 and the clamping strip 5 is tried to be inserted into the clamping groove 4, a certain resistance will be generated due to the width of the clamping groove 4 being slightly smaller than the sum of their thicknesses. However, it is this resistance that enables the mesh cloth 3 and the clamping strip 5 to fit more closely together when subjected to external pressure and smoothly slide into the clamping groove 4.

[0077] Once the combination of the mesh cloth 3 and the clamping strip 5 fully enters the clamping groove 4, they will maintain a stable form due to the restriction of the clamping groove 4 and are not prone to displacement or falling off. At the same time, due to the slightly smaller width of the clamping groove 4, it can also exert a clamping action on the mesh cloth 3 and the clamping strip 5 to some extent, thereby further enhancing the stability of the connection.

[0078] It is worth mentioning that this design not only improves the stability of the connection, but also makes the entire installation process more convenient and efficient. Users do not need to use additional fixing tools or materials, but only need to gently push the combination of the mesh cloth 3 and the clamping strip 5 into the clamping groove 4 to achieve quick and stable connection.

[0079] In summary, the embodiment successfully achieves the close fitting and stable connection of the mesh cloth 3 and the clamping strip 5 in the clamping groove 4 by skillfully adjusting the width of the clamping groove 4. This innovative design not only improves the overall stability and durability of the mesh frame body structure, but also provides users with a more convenient and efficient user experience.

[0080] Although the terms outer frame, inner frame, mesh cloth, etc. are used more in this application, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the utility model; any additional limitation on them is contrary to the spirit of the utility model.

[0081] The mesh frame body provided by the embodiment of the utility model, by skillfully adopting the strategy of dividing the frame body into two independent parts, specifically including an outer frame and an inner frame, and then the clamping groove for clamping the mesh cloth is formed between the four peripheral edges of the inner frame and the outer frame, so that the frame body structure can meet the established functional requirements and performance standards, and because the outer frame and the inner frame can be formed separately, the technical difficulty and process level requirement are greatly reduced, thereby facilitating the improvement of the overall production efficiency of the seat and ensuring that the final product meets higher standards and requirements in quality.

[0082] Embodiment two

[0083] The embodiment two of the utility model provides a seat, which comprises the mesh frame body provided in the above-mentioned embodiment one. This ingenious integration not only gives the seat a new appearance and texture, but also significantly improves comfort, durability and functionality.

[0084] Specifically, the seat in this embodiment can fully utilize the unique advantages of the above-mentioned net frame body and flexibly apply it to key parts such as the seat cushion, backrest, waist support and headrest. This design enables the seat to provide precise support and adjustment for each part according to different use requirements and ergonomic principles, thereby providing users with a more comfortable and healthy sitting experience.

[0085] For example, in the design of the seat cushion, the net frame body structure can be used to provide breathable and comfortable sitting sensation, while the elasticity and breathability of the mesh fabric can effectively relieve fatigue caused by long-time sitting. In the design of the backrest, the shape and size of the net frame body can be adjusted to perfectly fit the back curve, providing users with all-round support and protection.

[0086] In addition, the seat in this embodiment can also selectively configure additional components such as waist support and headrest according to the individual needs of users. These components can also be made of net frame body structure to ensure consistency with the overall style of the seat and further improve user comfort and satisfaction.

[0087] In summary, the second embodiment of the utility model successfully creates a seat product that is both beautiful and practical, comfortable and healthy, by introducing the net frame body structure of the first embodiment. This innovative design not only meets the users' pursuit of high-quality life, but also provides a new idea and direction for the future development of the seat industry.

[0088] Finally, it should be noted that although the above-mentioned embodiments have been described in the specification and drawings of this application, it does not limit the patent protection scope of this application. Any equivalent structure or equivalent process substitution or modification based on the essential concept of this application, using the content described in the specification and drawings, or directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of this application.
