[0031] In order for those skilled in the art to better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0032] As Figures 1 to 6 shown, the present application provides a case panel, comprising: a panel body 1, the panel body 1 is a plastic plate, the peripheral side of the panel body 1 comprises a plurality of panel corners 10; a metal sheet 2, the metal sheet 2 is embedded in the panel body 1 by injection molding process, the metal sheet 2 is arranged at least one of the plurality of panel corners 10.

[0033] In this way, the chassis panel of the present application sets the metal sheet 2 at the panel corner 10 of the panel body 1, and realizes the embedding of the two by using the injection molding process. By using the high rigidity of the metal sheet 2 and the lightweight characteristics of the plastic plate, the overall strength and anti-distortion performance of the panel body 1 are effectively improved, the rigidity of the panel body 1 is significantly strengthened, especially in resisting the deformation of the corner of the panel body 1, so that the panel body 1 is not easy to deform when bearing external force, the reliability and stability of the server are improved, and the overall weight or cost is not increased too much, realizing flexible chassis panel design, high production efficiency and structural integration, reducing the use of additional parts, and effectively solving the problem that the chassis panel in the prior art is difficult to balance low cost, high strength and simple structure.

[0034] The chassis panel of the present application is mainly applied in the field of servers, especially for large-size servers of 4U and above, which can significantly improve the strength of the chassis panel of the server, reduce the maintenance cost caused by the deformation of the chassis panel, and the combination of the panel body 1 and the metal sheet 2 ensures the rigidity of the chassis panel, supports the shape diversification of the panel body 1 (such as complex curved panels), while not affecting the appearance, also reduces the limitation of other process forming, and improves the user experience.

[0035] Optionally, the chassis panel of the present application can be widely applied to various server devices, whether it is a server in a large data center or a server in a home or small office environment, which can achieve better heat dissipation effect and structural stability, and its use process is to install the above-mentioned chassis panel on the server chassis during the assembly process of the server, to ensure the structural strength and heat dissipation effect of the chassis panel, thereby improving the reliability and performance of the server.

[0036] As shown in Figures 1 to 4 The panel body 1 includes: a frame 11, the frame 11 has a middle through slot 110; a plurality of first reinforcing ribs 12, each first reinforcing rib 12 extends along a first direction, and the plurality of first reinforcing ribs 12 are arranged at the middle through slot 110 along a second direction and are connected with the frame 11, so as to divide the middle through slot 110 into a plurality of slot segments 111; a plurality of heat dissipation parts 13, the plurality of heat dissipation parts 13 are arranged one by one corresponding to the plurality of slot segments 111, each heat dissipation part 13 includes a plurality of cross ribs 131, each cross rib 131 extends along the second direction, and the plurality of cross ribs 131 are arranged in the corresponding slot segment 111 along the first direction, and each cross rib 131 is connected with the frame 11 and / or the first reinforcing rib 12, so as to form a plurality of heat dissipation holes 132.

[0037] The chassis panel of the present application can improve the overall strength of the panel body 1 while forming the heat dissipation holes 132 with high ventilation rate by arranging multiple heat dissipation parts 13 on the panel body 1, connecting the horizontal ribs 131 with the frame 11 and the first reinforcing ribs 12. When the server (especially high-performance server) is running under high load, the heat dissipation holes 132 on the chassis panel can guide the air flow, effectively dissipate heat and take away the heat generated by each component inside the server, thereby improving the heat dissipation efficiency of the panel, ensuring the normal operation of each component and the stability and safety of the server operation. In addition, it can also reflect the scientific and technological lines of the chassis panel and reduce the overall distortion.

[0038] Specifically, the first direction is perpendicular to the second direction.

[0039] As shown in Figures 1 to 4 The panel body 1 further includes multiple second reinforcing ribs 14, each of which extends along the second direction, and the multiple second reinforcing ribs 14 are arranged one by one in the multiple slot sections 111, and each of the second reinforcing ribs 14 is connected with the frame 11 and / or the first reinforcing ribs 12; and / or the frame 11 includes multiple strip-shaped frame bodies 112 connected in sequence.

[0040] The chassis panel of the present application further arranges the second reinforcing ribs 14 on the panel body 1, which not only makes the panel body 1 have high strength, but also makes it have light weight and good ventilation effect, thereby improving the performance and user experience of the server.

[0041] In this way, the first reinforcing ribs 12 play a reinforcing role in the first direction on the panel body 1, and the second reinforcing ribs 14 play a reinforcing role in the second direction on the panel body 1, so as to jointly improve the structural performance and use experience of the panel in multiple dimensions.

[0042] Firstly, the arrangement of the first reinforcing ribs 12 and the second reinforcing ribs 14 significantly enhances the mechanical strength and deformation resistance of the panel body 1, especially when facing mechanical impact from the outside or long-term load. The first reinforcing ribs 12 and the second reinforcing ribs 14 are integrally injection molded with the panel body, forming an internal support framework, effectively dispersing the pressure acting on the panel body 1, avoiding the distortion and deformation of the panel at sensitive parts such as the four corners, and ensuring the geometric stability and structural integrity of the chassis panel during the server life cycle.

[0043] Secondly, the layout of the first reinforcing ribs 12 and the second reinforcing ribs 14 fully considers the heat dissipation demand inside the server, skillfully avoids the ventilation path, does not block the heat dissipation holes or ventilation slots on the panel body 1, thereby ensuring the high ventilation rate of the back of the panel body 1. This design not only promotes air flow and improves heat dissipation efficiency, but also reduces wind resistance and noise level when the server is running, providing important protection for stable operation of the server and healthy working environment for maintenance personnel.

[0044] Furthermore, the integrated design of the first reinforcing rib 12 and the second reinforcing rib 14 effectively saves the internal space of the server, reduces the need for additional support, simplifies the structure of the panel body 1, avoids unnecessary space occupation, and helps the compact layout of the internal components of the server, providing more space resources for high-performance computing, large-capacity storage, and other needs.

[0045] In addition, the first reinforcing rib 12 and the second reinforcing rib 14 also play a role in reducing costs. By directly forming the reinforcing rib in the injection molding process, the need for additional parts in the later assembly is avoided, reducing the assembly steps and reducing the material and labor costs. At the same time, the integrated molding also reduces the error in the manufacturing process, improving the quality and production efficiency of the product.

[0046] Finally, the first reinforcing rib 12 and the second reinforcing rib 14 also support the combination of aesthetics and functionality of the panel design, with their line design meeting the minimalist aesthetic pursued by the product, and their presence not affecting the appearance design of the panel, so that the panel can maintain high strength and heat dissipation performance while also meeting the high requirements of users for the appearance of technology products, improving the market competitiveness and user satisfaction of the product.

[0047] In summary, the first reinforcing rib 12 and the second reinforcing rib 14 enhance structural rigidity, improve heat dissipation performance, save space, reduce costs, and support the combination of aesthetics and functionality, together ensuring the efficient operation and long-term use of the panel in the server, embodying the innovation and practicality of the utility model in structural design.

[0048] Specifically, the width of the first reinforcing rib 12 is greater than the width of the horizontal rib 131, and the width of the second reinforcing rib 14 is greater than the width of the horizontal rib 131.

[0049] The chassis panel of the present application realizes lightweight and high ventilation rate by setting the frame 11 including a plurality of strip-shaped frame bodies 112, and is applied to server products pursuing high performance and lightweight design, especially to servers with strict requirements for heat dissipation, which can ensure alignment and connection with the corresponding structure on the chassis of the server during server assembly to achieve the best structural strength and heat dissipation effect.

[0050] As shown in Figure 5 and Figure 6 The metal sheet 2 also includes a main sheet body 21 and at least one first folded edge 22 arranged on the circumferential side of the main sheet body 21, and the first folded edge 22 is used to be embedded in the corresponding frame 11 or first reinforcing rib 12.

[0051] The chassis panel of the present application sets the metal sheet 2 as a structure including a main sheet body 21 and a first folded edge 22, in the injection molding process, the first folded edge 22 of the metal sheet is embedded in the corresponding frame 11 or the first reinforcing rib 12 on the panel body 1, realizing the stable and reliable combination of the metal sheet 2 and the panel body 1, improving the overall strength of the chassis panel, ensuring the structural stability of the chassis panel during use, so that the metal sheet 2 on the chassis panel can effectively disperse the force when it bears external force, preventing the chassis panel from deforming.

[0052] The metal sheet 2 in the chassis panel of the present application is processed by stamping process from metal sheet, which has good rigidity and can effectively improve the strength of the chassis panel and improve the deformation of the chassis panel.

[0053] Preferably, the metal sheet 2 can be a stainless steel sheet.

[0054] The main sheet body 21 of the metal sheet 2 in the chassis panel of the present application includes at least one connection group 211, the connection group 211 includes a plurality of connection strips 2111 extending along the second direction, and the plurality of connection strips 2111 are arranged in the first direction to form a plurality of avoiding holes 2112; wherein the connection group 211 is arranged corresponding to one of the plurality of heat dissipation parts 13, and the plurality of connection strips 2111 in the connection group 211 are arranged one by one at the plurality of cross ribs 131 in the corresponding heat dissipation part 13.

[0055] In this way, the main sheet body 21 of the metal sheet 2 in the chassis panel of the present application is arranged corresponding to the heat dissipation part 13 through the connection group 211, which ensures that the combination between the metal sheet 2 and the plastic panel body 1 will not affect the ventilation effect of the heat dissipation hole 132 of the corresponding heat dissipation part 13, and at the same time ensures that the chassis panel can maintain a high ventilation rate while ensuring the close and stable combination between the metal sheet 2 and the panel body 1, ensuring the heat dissipation demand of the server.

[0056] As shown in Figure 5 and Figure 6 The main sheet body 21 includes two connection groups 211, each connection group 211 includes a plurality of connection strips 2111 extending along the second direction, and the plurality of connection strips 2111 are arranged in the first direction to form a plurality of avoiding holes 2112; wherein the two connection groups 211 are arranged corresponding to the two adjacent heat dissipation parts 13 respectively, and the plurality of connection strips 2111 in each connection group 211 are arranged one by one at the plurality of cross ribs 131 in the corresponding heat dissipation part 13.

[0057] Specifically, the number of the connection groups 211 is multiple, the main sheet body 21 includes a strip-shaped plate body 212, two adjacent connection groups 211 are connected through the strip-shaped plate body 212, the strip-shaped plate body 212 is arranged correspondingly to the first reinforcing rib 12 between the corresponding two adjacent heat dissipation parts 13; and / or the connecting strip 2111 is located on the inner side of the corresponding horizontal rib 131, and the connecting strip 2111 is attached to the corresponding horizontal rib 131; at least one side of the avoiding hole 2112 is provided with a second folding edge 23, and the second folding edge 23 is used for embedding into the corresponding frame 11 or the first reinforcing rib 12.

[0058] The main sheet body 21 of the present application realizes the uniform distribution and close attachment of the metal sheet and the plastic panel by arranging multiple connection groups 211 and strip-shaped plate bodies 212, and attaching the connecting strip and the horizontal rib, so as to ensure that the cabinet panel can uniformly disperse force when bearing external force, reduce the risk of excessive local stress, and improve the overall impact resistance of the cabinet panel.

[0059] Specifically, the width of the connecting strip 2111 does not exceed the width of the corresponding horizontal rib 131, so as to ensure that the cabinet panel can have a higher ventilation rate.

[0060] The arrangement of the second folding edge 23 in the main sheet body 21 of the present application embeds the second folding edge 23 into the corresponding frame 11 or the first reinforcing rib 12, thereby enhancing the structural stability and bonding strength between the metal sheet 2 and the panel body 1 of the plastic, and further improving the resistance of the cabinet panel when bearing external impact or pressure, which helps to improve the overall anti-distortion performance of the cabinet panel, especially when the cabinet panel size is large, the corner is prone to deformation, and local reinforcement of the metal sheet can effectively prevent this problem, maintain the geometric precision of the cabinet panel, prolong its service life, and reduce the dependence on reinforcing members other than the metal sheet 2, simplify the structure of the cabinet panel, reduce the complexity of manufacturing and assembling the cabinet panel, and be conducive to cost control and production efficiency improvement.

[0061] Among them, the second folding edge 23 in the main sheet body 21 is arranged on the side of the corresponding avoiding hole 2112 close to the corresponding strip-shaped plate body 212, so as to be embedded into the corresponding first reinforcing rib 12.

[0062] Optionally, the connecting strip 2111 is provided with one glue grabbing hole 2113; and / or the connecting strip 2111 is provided with multiple glue grabbing holes 2113, and the multiple glue grabbing holes 2113 are arranged at intervals along the extension direction of the corresponding connecting strip 2111.

[0063] The metal sheet 2 of the present application ensures the strength of itself, processes a plurality of glue grabbing holes 2113 on the connecting strip 2111 through stamping, uses the plastic flow in the injection molding process, combines the material flowing into the glue grabbing hole 2113 with the connecting strip 2111, forms a firm glue grabbing effect, realizes the close connection between the connecting strip 2111 and the cross rib 131, further improves the distortion degree of the panel body 1, improves the bonding strength between the metal sheet 2 and the panel body 1, so that the metal sheet 2 and the panel body 1 will not separate in long-term use, improves the durability of the case panel, and will not occupy additional space, supports lightweight design, can ensure high ventilation rate, and ensure normal operation of the whole machine. In addition, it also supports the diversification design of the appearance modeling of the case panel, and improves the user experience.

[0064] As shown in Figure 5 and Figure 6 , the connecting strip 2111 is provided with three glue grabbing holes 2113, the three glue grabbing holes 2113 are arranged at intervals along the extension direction of the corresponding connecting strip 2111, and each glue grabbing hole 2113 is a long circular hole. In this way, first, the setting of the long circular hole increases the contact area and the glue grabbing strength between the steel sheet and the plastic shell, which not only effectively improves the overall rigidity of the panel, but also significantly reduces the deformation and distortion of the panel during use, especially during transportation and installation, can better resist external pressure and impact, ensure the stability and durability of the panel structure, and can form a more firm mechanical connection during injection molding. When the plastic solidifies, it can penetrate deeper into the hole, forming a structure similar to mortise and tenon, further enhancing the bonding force between the metal sheet 2 and the panel body 1, making the combination between them more reliable, even in long-term use or high-temperature environment, it can also maintain good interface adhesion, avoid separation or damage due to thermal expansion and contraction. Furthermore, the design of the long circular hole also considers the feasibility of the manufacturing process. Compared with simple circular or square holes, the long circular hole is more suitable for the material properties of the steel sheet during stamping and molding, avoiding cracks or damage caused by stress concentration at the hole edge, ensuring the integrity and structural strength of the steel sheet. At the same time, during the injection molding process, the long circular hole shape is also conducive to the flow and distribution of the plastic shell material, reducing molding defects and improving product qualification rate. Finally, the design of the long circular hole not only meets the functional requirements, but also reduces the influence of the hole on the appearance of the product to a certain extent, so that the panel can maintain high strength while maintaining high appearance quality, embodying the perfect combination of technology and aesthetics, improving the market competitiveness and user satisfaction of the product.

[0065] As shown in Figure 6 , the metal sheet 2 further comprises a material belt 24, the material belt 24 is located on the side of the main sheet body 21 away from the panel body 1 and connected with the main sheet body 21, and the material belt 24 is provided with a positioning hole 241.

[0066] The chassis panel of the present application sets the metal sheet 2 at the correct position of the mold through the positioning hole 241 on the material belt 24 before injection molding, realizes the accurate positioning of the metal sheet 2 in the injection molding process, ensures the accurate combination of the metal sheet 2 and the panel body 1, improves the manufacturing precision and appearance quality of the chassis panel, especially suitable for the chassis panel of the server which needs high-precision positioning, can improve the production efficiency, reduce the production cost, and at the same time ensure the stability and reliability of the product structure. In addition, since the main role of the material belt 24 is before and during injection molding, after injection molding, its auxiliary role no longer exists, so when the chassis panel is injection molded, the root of the material belt 24 can be cut off to separate the material belt 24 from the main sheet body 21, so as not to affect the appearance of the chassis panel.

[0067] Optionally, the positioning hole 241 can be a round hole or an oval hole.

[0068] Specifically, the number of metal sheets 2 is multiple, and the multiple metal sheets 2 are one-to-one correspondingly arranged at the multiple panel corners 10.

[0069] Because the overall size of the plastic panel body 1 is large, the panel corner 10 is easy to twist and deform, and obvious deformation and distortion may occur after single-piece molding, therefore, the chassis panel of the present application sets the metal sheet 2 at the correct position of the mold through the positioning hole 241 on the material belt 24 before injection molding, realizes the accurate positioning of the metal sheet 2 in the injection molding process, ensures the accurate combination of the metal sheet 2 and the panel body 1, improves the manufacturing precision and appearance quality of the chassis panel, especially suitable for the chassis panel of the server which needs high-precision positioning, can improve the production efficiency, reduce the production cost, and at the same time ensure the stability and reliability of the product structure. In addition, since the main role of the material belt 24 is before and during injection molding, after injection molding, its auxiliary role no longer exists, so when the chassis panel is injection molded, the root of the material belt 24 can be cut off to separate the material belt 24 from the main sheet body 21, so as not to affect the appearance of the chassis panel.

[0071] Specifically, the material belt 24 includes a first strip-shaped connecting piece and at least one second strip-shaped connecting piece, the first strip-shaped connecting piece is parallel to the length direction of the main sheet body 21, the second strip-shaped connecting piece is perpendicular to the length direction of the main sheet body 21, the first strip-shaped connecting piece is located on the side of the second strip-shaped connecting piece away from the main sheet body 21, the first strip-shaped connecting piece is connected with the main sheet body 21 through the second strip-shaped connecting piece, and the positioning hole 241 is arranged on the first strip-shaped connecting piece.

[0072] As shown in Figure 6As shown, the material belt 24 includes a first strip-shaped connecting piece parallel to the length direction of the main piece body 21 and two second strip-shaped connecting pieces each perpendicular to the length direction of the main piece body 21, the first strip-shaped connecting piece is located on the side away from the main piece body 21 of the two second strip-shaped connecting pieces, one end of each second strip-shaped connecting piece is connected with the first strip-shaped connecting piece, and the other end of each second strip-shaped connecting piece is connected with the main piece body 21.

[0075] The server of the present application also provides a server comprising the above-mentioned case panel. The server of the present application utilizes the high strength, high ventilation rate and lightweight characteristics of the above-mentioned case panel to improve the overall performance and user experience of the server. When the server is subjected to external force, the case panel is not easy to deform, and at the same time, when the server is running under high load, the case panel can effectively dissipate heat to ensure the normal operation of the components inside the server.

[0076] The case panel is usually located at the front or rear of the server and is an important component of the server case structure. It is usually designed as a flat or curved structure to protect the electronic components inside the server, such as the motherboard, hard disk, power supply and cooling system, from external environmental factors such as dust, liquid splashing or physical impact, not only providing physical protection, but also playing a key role in heat dissipation and ventilation, helping the internal components of the server to dissipate heat through the design of heat dissipation holes or ventilation grooves on the panel, maintaining the stable operation of the server under high load. In addition, the case panel often may be integrated with indicator lights, switches, USB interfaces and other external interfaces for user operation and monitoring of the server status. In the present application, the case panel is designed with a unique combination of stainless steel sheets and reinforcing ribs to improve the mechanical strength of the panel, improve the heat dissipation performance, achieve lightweight and improve the user experience, which is a key structure for the appearance design and functionality of the server.

[0077] Specifically, the server of the present application is widely used in the fields of data centers, high-performance computing, cloud computing, etc.

[0078] The server of the present application can be a 4U server, which refers to a server designed with a 4U (4 Unit) standard height. In the server industry, "U" is a standard unit used to measure the height of a server rack or chassis. 1U is approximately equal to 44.45 millimeters (1.75 inches), so the height of a 4U server is about 177.8 millimeters (7 inches); due to its larger physical size, a 4U server usually provides more spacious internal space, which allows for the installation of more hardware components, such as more hard drives, larger power supplies, more powerful cooling systems, etc. This design is very suitable for application scenarios that require high performance, high storage capacity, and strong cooling capacity, such as high-load applications in data centers, high-performance computing (HPC) systems, storage servers, or server environments that require expansion cards and additional cooling.

[0079] The technical effects of the chassis panel and server of the present application are as follows:

[0080] (1) Cost savings: embedding the metal sheet 2 into the plastic panel body 1 through injection molding significantly reduces material and manufacturing costs compared to using an all-metal panel or adding additional metal supports to an all-plastic panel, achieving economic optimization.

[0081] (2) Strength improvement: the embedding of the metal sheet 2 effectively enhances the mechanical strength of the panel body 1, especially in the four corners and other areas prone to deformation of the panel body 1. Through reliable glue grabbing between the metal sheet 2 and the panel body 1, the anti-twisting and anti-deformation capabilities of the panel body 1 are improved, enhancing the stability and durability of the overall structure, so that the panel body 1 is not easily deformed when subjected to external forces, thereby improving the reliability and stability of the server.

[0082] (3) Design flexibility: supports the design of a variety of complex curved surfaces for the chassis panel, improving the appearance appeal and user experience of the chassis panel product, while reducing the limitations of other molding processes such as metal plate bending and welding, making the design of the chassis panel more flexible.

[0083] (4) Space saving and lightweight: the present application does not occupy additional space and does not increase the overall weight or cost, supports lightweight design, is conducive to the overall structural optimization and space utilization of the server, and reduces the weight of the server, facilitating transportation and installation.

[0084] (5) High ventilation rate: the panel design ensures a high ventilation rate, meeting the ventilation needs of the internal cooling elements of the server, ensuring the normal operation of the entire machine, avoiding local overheating in the server, and prolonging the service life of the server.

[0085] (6) Process simplification: the combination of the panel body and the stainless steel sheet is completed at one time by injection molding, reducing the use of additional parts, without the need for complex post-processing or additional assembly steps, improving production efficiency and quality consistency.

[0086] (7) Maintenance convenience: due to the lightweight of the panel body 1 and the reliable embedding of the metal sheet 2, high production efficiency and structural integration are achieved, making the server more convenient to operate when maintaining and replacing the panel, reducing maintenance cost and time.

[0087] In summary, the case panel design of the present application realizes the comprehensive effect of low cost, high strength, simple structure, lightweight, high ventilation rate and maintenance convenience through technical innovation, which is a major progress in the field of server technology.
