When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0033] like Figures 1 to 7 The panel structure shown includes: a plastic foam body and a support frame 2; the plastic foam body is in the shape of a "concave" panel structure, including an outer panel 11, an inner panel 12 arranged parallel to the outer panel 11, and a side wall 13 connecting the outer panel 11 and the inner panel 12; the support frame 2 is connected to the inner panel 12, and the support frame 2 is at least partially embedded relative to the side wall 13, and the plastic foam body covers the support frame 2; wherein the plastic foam body and the support frame 2 are spliced together. Figure 1 and Figure 2 As shown, it should be noted that the outer panel 11 refers to the side on the outside of the panel structure, that is, the side in contact with the outside world, and the inner panel 12 is a side parallel to the outer panel 11 and arranged inside the panel structure. The outer panel 11 and the inner panel 12 are connected by the side wall 13 to form a panel structure. The outer panel 11 provides good surface strength, the inner panel 12 provides a supporting base for the support frame 2, and the side wall 13 enhances the overall structural stability. The support frame 2 is partially embedded in the plastic foam body to achieve better load distribution and shock absorption effects, and the plastic foam body completely covers it. The utility model improves the strength and durability of the panel, while reducing the overall weight through the lightweight characteristics of the plastic foam material; the embedded design of the support frame 2 enhances the stability and load-bearing capacity of the panel, making it more pressure-resistant in actual applications. This structure helps to effectively reduce shock and sound, and provide a comfortable user experience.
[0034] In some embodiments of the present invention, the plastic foam body is made of expanded polypropylene. The preparation process of the expanded polypropylene (EPP) material mainly includes the following steps:
[0035] Raw material preparation: polypropylene (EPP) resin is used as the base material, and an appropriate amount of foaming agent is prepared. The foaming agent includes paraffin, nitrogen or chemical foaming agent, etc.;
[0036] Mixing: In a high-speed mixer, the polypropylene resin is uniformly mixed with the foaming agent. This process can be modified by physical mixing or using additives to improve the properties of the material;
[0037] Extrusion, the mixture is fed into the extruder, through heating, the polypropylene melts and the foaming agent begins to release gas;
[0038] Foaming: During the extrusion process, the release of gas causes the material to expand and form foam. At this time, parameters such as the density, porosity and thickness of the foam can be controlled by adjusting the extrusion temperature, pressure and the amount of foaming agent;
[0039] Cooling and solidification: the foamed material is quickly cooled by a cooling device and solidified into shape. Cooling can be achieved by water bath or air cooling to stabilize the foam structure.
[0040] Cutting and forming: Cutting the cured foam into the desired shape and size, usually by thermal cutting or mechanical cutting. At this point, further processing and surface treatment can be performed according to specific application requirements;
[0041] Inspection, conduct physical property tests such as compressive strength, density, resilience, etc. to ensure that the product meets the standards and conduct necessary quality control.
[0042] It's important to note that EPP offers excellent mechanical properties, including excellent impact and pressure resistance and low water absorption. Its lightweight construction makes it easier to handle and install, while its foam structure effectively insulates and reduces vibration, enhancing user comfort. Furthermore, EPP is recyclable, environmentally friendly, and suitable for a wide range of applications.
[0043] In some embodiments of the present invention, the load-bearing surface of the outer panel 11 is a curved surface, and the connection between the load-bearing surface and the side wall 13 is a smooth transition. Figure 1 and Figure 2 As shown, the load-bearing surface of the outer panel 11 is designed to be curved, evenly distributing the load and reducing concentrated stress. The curved surface can be an arc or other continuous curve, with a smooth transition at the junction with the sidewall 13 to ensure there are no sharp edges between the load-bearing surface and the sidewall 13. This smooth transition can take the form of a curved or gradual curve, optimizing fluid dynamics and enhancing the overall aesthetics of the structure.
[0044] In order to ensure the stability of the panel structure, a reinforcing rib 121 is provided on the inner panel 12. Figure 2 As shown, the inner panel 12 is provided with reinforcing ribs 121 to enhance its rigidity and load-bearing capacity. Ribs 121 can be strip-shaped or otherwise arranged along specific directions along the inner panel 12 to effectively support it and distribute loads. The presence of ribs 121 effectively prevents deformation under load, reduces material usage, and reduces overall weight without compromising structural strength, thereby improving energy efficiency. Overall, this extends the service life of the inner panel 12, ensuring product reliability in high-stress applications.
[0045] Furthermore, the reinforcing rib 121 includes an outer reinforcing frame 121a and an inner reinforcing beam 121b. The outer reinforcing frame 121a is adapted to the inner surface of the side wall 13, and the inner reinforcing beam 121b is configured to abut against the outer reinforcing frame 121a and be arranged in a cross-sectional manner inside the outer reinforcing frame 121a. Figure 2 The reinforcing ribs 121 are composed of an outer reinforcing frame 121a and an inner reinforcing beam 121b. The outer reinforcing frame 121a is adapted to the inner surface of the side wall 13 to form a stable boundary, thereby enhancing the overall structural strength of the inner panel 12; the inner reinforcing beam 121b is cross-arranged inside the outer reinforcing frame 121a, offsetting the outer reinforcing frame 121a, thereby providing additional support and load distribution. Through this cross layout, the inner reinforcing beam 121b can effectively offset stresses from different directions, especially in the case of uneven force or impact loads, and can more effectively disperse and bear external pressure. In addition, the crossed inner reinforcing beams 121b can reduce deformation and extrusion of the panel and improve torsional resistance.
[0046] Optionally, the reinforcement rib 121 further includes a main reinforcement beam 121c and an auxiliary reinforcement beam, wherein the cross section of the main reinforcement beam 121c is larger than that of the auxiliary reinforcement beam. Figure 2 The main reinforcement beam 121c primarily bears the bulk of the load, providing critical support and rigidity. It is located at the center of the panel structure, or in areas of concentrated stress. The auxiliary reinforcement beams are positioned around the main reinforcement beam 121c to enhance structural stability and distribute the load. The large cross-section of the main reinforcement beam 121c ensures strength at the critical load-bearing locations, while the placement of the auxiliary reinforcement beams optimizes stress distribution within the panel, preventing localized deformation or failure.
[0047] Furthermore, the reinforcing ribs 121 constitute a splicing mechanism 14, and the splicing mechanism 14 includes a splicing piece 141 provided on the reinforcing ribs 121. Figure 3 and Figure 4As shown, the splicing mechanism 14 composed of the reinforcing ribs 121 is connected and combined by the splicing pieces 141 set thereon. The splicing pieces 141 can be specially designed, or they can be connected by conventional plug-in, snap-on or bolt connections to ensure a firm connection between the reinforcing ribs 121 or with other structural parts. The design of the splicing pieces 141 can select suitable materials and shapes according to specific application requirements. The setting of the splicing mechanism 14 improves the flexibility and assemblability of the structure, making it more convenient during the production and installation process. Through the splicing pieces 141, the structure can be quickly replaced or adjusted as needed, which improves the efficiency of maintenance and repair.
[0048] On the basis of the above embodiment, the splicing mechanism 14 further includes a splicing groove 142 opened on the plastic foam body, and the splicing piece 141 is adapted to the splicing groove 142 and can be buckled into the splicing groove 142. Figures 3 to 7 As shown, the splicing groove 142 is adapted to the splicing piece 141, and the splicing piece 141 can be easily snapped into it. The shape and size of the splicing groove 142 are precisely calculated to ensure that the splicing piece 141 can be firmly embedded while being easy to install and disassemble. In some embodiments, a multi-step stepped splicing piece 141 is used, and the splicing groove 142 is provided with a notch adapted thereto. This arrangement can more effectively prevent the support frame 2 from falling off during the installation process, further improving the stability of its structure. The adaptation of the splicing piece 141 and the splicing groove 142 makes the connection between the reinforcing rib 121 and the plastic foam body tighter, avoiding loosening due to movement or external force. In addition, the provision of the splicing groove 142 simplifies the assembly process, and the user can quickly complete the installation, saving time and manpower.
[0049] According to another aspect of the present invention, there is also provided an assembled seat, comprising a seat body and a connector, wherein the seat body provides support for the assembled seat, and the connector is an armrest and / or backrest spliced with the seat body; wherein at least the connector adopts the above-mentioned panel structure. The panel structure of the connector adopts reinforcing ribs and a splicing mechanism to ensure its load-bearing capacity and durability. The design of the armrest and backrest can be flexibly selected and configured as needed, thereby enhancing the comfort and user experience of the seat. The splicing setting of the connector allows the various parts to be easily assembled and disassembled, and is convenient for transportation and maintenance. In this way, the assembled seat has advantages in functionality and aesthetics, is suitable for a variety of applications, and improves overall safety, while the splicing design provides convenient installation and replacement options to meet the needs and preferences of different users, thereby improving the market competitiveness of the product.
[0050] Specifically, the seat body includes a support member, which is detachably connected to the support frame. The support member and the support frame can still be connected using the aforementioned bolts, snaps, or plug-in connections, ensuring a secure connection between the support member and the support frame while allowing for quick detachment when needed. This detachable design provides flexibility, making the seat assembly, transportation, and storage more convenient. Users can adjust the position of the support member or replace it with a different type of support member as needed to meet different usage requirements.
