[0032] With the continuous development of the children's educational toy market, magnetic panel building toys 300, which combine fun and creativity, are highly favored by consumers because they allow children to freely assemble various shapes. The core component of this type of toy is the magnetic panel, whose structure generally includes a magnetic mechanism and a baffle 200. The magnetic mechanism is used to connect with other panels, and the baffle 200 serves as the splicing surface. Through the magnetic mechanism, different forms such as playhouses and creative shapes can be constructed. However, existing magnetic panels have complex structures and cumbersome assembly processes.

[0033] During installation, the combination of the frame and the baffle 200 relies heavily on traditional snap-fit ​​or adhesive processes. Snap-fit ​​structures are prone to loosening and snap-fit ​​breakage due to long-term insertion and removal, leading to a decrease in the overall stability of the panel. Adhesive processes are affected by the performance of the adhesive and the uniformity of the adhesive application, resulting in low assembly efficiency and the baffle 200 easily detaching from the frame after the adhesive ages. At the same time, traditional assembly methods do not adequately control the integration of the magnetic component 120, resulting in poor compatibility between the magnetic component 120 and the frame and baffle 200, which can easily lead to problems such as inaccurate magnetic alignment and uneven magnetic force, affecting the toy assembly experience and lifespan, and making it difficult to meet the market demand for high-quality magnetic assembly toys 300.

[0034] This utility model proposes a frame.

[0035] Please see Figure 1 , Figure 2 as well as Figures 4 to 8 , Figure 2 Part C in the diagram is a partially enlarged view of the frame. In one embodiment of this utility model, it includes: a frame body 100, the frame body 100 forming a first receiving space 110, the receiving space being provided with a magnetic suction member 120, and a limiting space 130 for mounting a panel being formed on the inner side of the frame body 100.

[0036] The technical solution of this utility model adopts a first receiving space 110 on the frame body 100, and a magnetic suction component 120 is provided in the receiving space. A limiting space 130 for installing the panel is formed on the inner side of the frame body 100. The panel can be placed in the limiting space 130 to complete the assembly, which improves the assembly efficiency of the magnetic suction panel.

[0037] See Figures 4 to 8 For ease of installation, in one embodiment, the frame body 100 further includes a lower frame 140 and an upper frame 150.

[0038] The lower frame 140 is provided with a first mounting groove 141, and the inner side of the lower frame 140 is provided with a second mounting groove 142. The upper frame 150 is provided with a third mounting groove 151, and the inner side of the upper frame 150 is provided with a fourth mounting groove 152. The upper frame 150 and the lower frame 140 are detachably connected. The third mounting groove 151 and the first mounting groove 141 form the first receiving space 110, and the fourth mounting groove 152 and the second mounting groove 142 form the limiting space 130.

[0039] In this embodiment, to address the problems of low assembly efficiency, poor structural stability, and insufficient compatibility of the magnetic components 120 in existing magnetic panels, a split-type configuration is adopted for the frame body 100, which includes a lower frame 140 and an upper frame 150. The assembly of the magnetic panel can be completed simply by placing the baffle 200 in the second mounting slot 142 or the fourth mounting slot 152 and closing the upper frame 150 and the lower frame 140, thereby improving the assembly efficiency of the magnetic panel.

[0040] Specifically, the lower frame 140 is provided with a first mounting groove 141 and an inner second mounting groove 142, and the upper frame 150 is provided with a corresponding third mounting groove 151 and an inner fourth mounting groove 152. When the upper and lower frames 140 are combined, the first mounting groove 141 of the lower frame 140 and the third mounting groove 151 of the upper frame 150 are spliced ​​to form a first receiving space 110 for accommodating the magnetic component 120. This space provides a precise installation area for the magnetic component 120, ensuring that the position of the magnetic component 120 in the frame body 100 is fixed and that it can be accurately aligned with the magnetic attraction mechanism of the adjacent panel. At the same time, the second mounting groove 142 of the lower frame 140 and the fourth mounting groove 152 of the upper frame 150 form a limiting space 130 inside the frame body 100 for supporting the baffle 200 as the splicing surface. In actual assembly, simply place the baffle 200 into the second mounting slot 142 of the lower frame 140 or the fourth mounting slot 152 of the upper frame 150, then align the upper frame 150 with the lower frame 140 and complete the detachable connection. This simultaneously achieves the positioning and installation of the magnetic component 120 and the limiting and fixing of the baffle 200. This split-type splicing and dual-slot design simplifies the traditionally step-by-step integration of the magnetic component 120 and fixing of the baffle 200 into the alignment and fastening of the upper and lower frames 140, significantly reducing the assembly steps.

[0041] The detachable upper and lower frame 140 structure forms a double limit on the magnetic component 120 and the baffle 200 through the precise matching of the mounting slots: the first receiving space 110 uses the combined structure of the upper and lower frame 140 to stably clamp the magnetic component 120 in the preset position, avoiding the problems of misalignment and uneven attraction caused by the positioning deviation of the magnetic component 120 in the traditional method; the limiting space 130 provides a four-sided constraint on the baffle 200 through the encirclement of the mounting slots on the inner side of the upper and lower frame 140.

[0042] This avoids the risk of detachment caused by glue aging in the adhesive bonding process. Since the entire assembly process requires no additional auxiliary tools or adhesive steps and can be completed solely through the cooperation of mechanical structures, production efficiency is significantly improved, and the structural stability of the magnetic panel is ensured during long-term use.

[0043] See Figures 4 to 8 Specifically, in one embodiment, the lower frame 140 includes a first mounting portion 143, a first sidewall 144 is provided on one side edge of the first mounting portion 143, and a second sidewall 145 is provided on the other side edge of the first mounting portion 143. The first sidewall 144, the second sidewall 145 and the first mounting portion 143 form a first mounting groove 141 and a second mounting groove 142. A fifth mounting groove 146 is provided on the first mounting groove 141. The upper frame 150 includes a second mounting portion 153. A third sidewall 154 is provided on one side edge of the second mounting portion 153, and a fourth sidewall 155 is provided on the other side edge of the first mounting portion 143. The third sidewall 154, the fourth sidewall 155 and the second mounting portion 153 form the third mounting groove 151 and the fourth mounting groove 152. A sixth mounting groove 156 is provided on the first mounting groove 141. One end of the magnetic suction member 120 is connected to the fifth mounting groove 146, and the other end of the magnetic suction member 120 is connected to the sixth mounting groove 156.

[0044] In this embodiment, a first sidewall 144 and a second sidewall 145 are respectively provided on both sides of the first mounting portion 143 of the lower frame 140, and the three together form a first mounting groove 141 and a second mounting groove 142, and a fifth mounting groove 146 is added on the first mounting groove 141; a third sidewall 154 and a fourth sidewall 155 are respectively provided on both sides of the second mounting portion 153 of the upper frame 150, forming a third mounting groove 151 and a fourth mounting groove 152, and a sixth mounting groove 156 is provided on the third mounting groove 151. During assembly, one end of the magnetic component 120 is embedded into the fifth mounting groove 146 of the lower frame 140. When the upper frame 150 is joined to the lower frame 140, the fifth mounting groove 146 precisely aligns with the sixth mounting groove 156. The other end of the magnetic component 120 connects to the sixth mounting groove 156 of the upper frame 150, forming a stable clamp and limit on the magnetic component 120 from both ends, ensuring that the magnetic component 120 will not shift or loosen within the first receiving space 110. At the same time, the limiting space 130 formed by the second mounting groove 142 and the fourth mounting groove 152 can precisely fix the baffle 200, keeping it stable during the assembly process.

[0045] The magnetic component 120 is connected at both ends to the fifth and sixth mounting slots 156 respectively. Utilizing the shape adaptation and locking effect of the slots, the magnetic component 120 is firmly locked within the first receiving space 110, preventing it from shaking or shifting during use and ensuring accurate magnetic alignment and balanced suction force. The limiting space 130 formed by the second mounting slot 142 and the fourth mounting slot 152, with the constraint of the surrounding side walls, ensures that the baffle 200 is evenly distributed when subjected to splicing external force, effectively preventing loosening or detachment due to excessive local force. Compared with traditional structures, this design greatly enhances the structural strength of the magnetic panel.

[0046] See Figures 4 to 8 In one embodiment, the second sidewall 145 is provided with at least one first slot 147, and the fourth sidewall is provided with at least one first engaging portion 157, the first engaging portion 157 engaging with the first slot 147.

[0047] In this embodiment, to further enhance the stability of the detachable connection between the upper frame 150 and the lower frame 140 and ensure the structural reliability of the magnetic panel during assembly, the connection method of the frame body 100 is optimized by providing a first slot 147 and a first engaging part 157 that cooperate with each other on the second side wall 145 and the fourth side wall 155. This solves the problem of loosening after long-term use of traditional connection methods, while improving the convenience and stability of overall assembly.

[0048] Specifically, at least one first slot 147 is provided on the second side wall 145 of the lower frame 140, and at least one first engaging portion 157 is provided on the fourth side wall 155 of the upper frame 150. During magnetic panel assembly, simply align the corresponding positions of the upper frame 150 and the lower frame 140, and then insert the first engaging portion 157 into the first slot 147 to quickly connect and fix the upper and lower frames 140. This snap-fit ​​structure design is based on the snap-fit ​​principle of a mechanical structure, utilizing the tight fit between the first engaging portion 157 and the first slot 147 to create a mechanical locking effect. During insertion into the first slot 147, the first engaging portion 157 undergoes a certain elastic deformation. When fully embedded in the slot, its elastic recovery causes the two to mesh tightly, providing a stable connection force and limiting the relative displacement of the upper and lower frames 140 after assembly.

[0049] The snap-fitting of the first slot 147 and the first engaging part 157 provides precise positioning for the connection of the upper and lower frames 140, ensuring accurate alignment between the first mounting slot 141 and the third mounting slot 151, and between the second mounting slot 142 and the fourth mounting slot 152, thus guaranteeing the installation accuracy of the magnetic component 120 and the baffle 200. Furthermore, compared to traditional simple snap-fit ​​structures, this snap-fit ​​method enhances the strength of the connection by optimizing the shape, size, and fit tolerances of the slot and engaging part. During the use of the magnetic panel, even when subjected to external force such as pulling or collision during child assembly, the snap-fitting structure of the first slot 147 and the first engaging part 157 effectively disperses stress, preventing connection failure due to excessive localized force and ensuring the integrity of the overall structure of the magnetic panel. Simultaneously, the snap-fitting operation is simple and quick, requiring no additional tools or complex processes, improving assembly efficiency and facilitating later maintenance and component replacement of the magnetic panel.

[0050] The cooperation between the first slot 147 and the first engaging part 157 not only significantly shortens the connection time of the upper and lower frames 140, but also significantly enhances the structural strength of the frame body 100. In practical use, when children freely assemble magnetic panel toys, they do not need to worry about the upper and lower frames 140 becoming loose, affecting the assembly experience or causing parts to fall off; moreover, this stable connection method also improves the durability of the magnetic panels, extends the product's lifespan, and improves the quality of the magnetic assembly toy 300.

[0051] See Figures 4 to 8 In one embodiment, the first sidewall 144 is further provided with a second slot 148, and the third sidewall 154 is further provided with a second engaging portion 158, which engages with the second slot 148.

[0052] In this embodiment, in order to further improve the reliability and structural integrity of the connection between the upper frame 150 and the lower frame 140, a second slot 148 and a second engaging part 158 ​​are added to the first side wall 144 and the third side wall 154 to strengthen the detachable connection of the frame body 100, avoid the problem of uneven force distribution or local loosening that may exist in a single snap-fit ​​structure, and enhance the overall resistance to external forces.

[0053] In terms of specific construction, the first sidewall 144 of the lower frame 140 is provided with a second slot 148, and the third sidewall 154 of the upper frame 150 is correspondingly provided with a second engaging part 158. During the magnetic panel assembly operation, the upper frame 150 and the lower frame 140 are aligned to ensure that the second engaging part 158 ​​and the second slot 148 are precisely aligned. Utilizing the fit tolerance and elastic deformation characteristics between the two, the second engaging part 158 ​​is embedded into the second slot 148. This engagement process is based on the interference fit principle in mechanical engineering. When the second engaging part 158 ​​is inserted into the slot, it undergoes elastic compression. After being fully embedded, the clamping force generated by the elastic recovery of the material achieves a tight engagement between the two, thereby forming a stable mechanical connection.

[0054] The snap-fit ​​pair formed by the second slot 148 and the second engaging part 158, together with the first slot 147 and the first engaging part 157 on the second side wall 145, forms a spatially symmetrical constraint system. When the magnetic panel is subjected to external force, this double-symmetrical snap-fit ​​structure can evenly distribute the external force to the four connection points of the upper and lower frames 140, avoiding cracks on the upper frame 150 and / or lower frame 140 due to local stress concentration in a single snap-fit ​​structure. Compared with the traditional single snap-fit ​​design, this solution significantly improves the shear and torsional resistance of the connection interface of the upper and lower frames 140 by adding a set of snap-fit ​​structures, ensuring that the dimensional accuracy of the first accommodating space 110 and the limiting space 130 is maintained during repeated operations such as splicing and disassembly, and ensuring the stability of the installation position of the magnetic component 120 and the baffle 200. At the same time, this double snap-fit ​​structure design does not affect the rapid assembly process of the upper and lower frames 140. Operators only need to complete the two sets of snap-fit ​​engagements simultaneously during routine alignment operations to achieve a reliable connection of the frame body 100. After the magnetic panel frame is assembled, the connection strength between its upper and lower frames 140 is improved.

[0055] See Figures 4 to 8In one embodiment, the second slot 148 is further provided with an adhesive, and the second engaging part 158 ​​is fixed in the second slot 148 by the adhesive.

[0056] In this embodiment, to further enhance the stability of the connection between the upper frame 150 and the lower frame 140 and to solve the problem that the simple mechanical snap-fit ​​may loosen under extreme use environment or long-term stress, an adhesive is added in the second slot 148 to combine the mechanical snap-fit ​​with chemical bonding to form a composite connection structure, thereby improving the overall reliability and durability of the frame body 100.

[0057] In practice, before assembling the magnetic panel frame, a suitable amount of adhesive is applied to the inside of the second slot 148. Then, the upper frame 150 with the second engaging part 158 ​​is aligned and installed with the lower frame 140. During the insertion of the second engaging part 158 ​​into the second slot 148, the adhesive evenly fills the tiny gaps between the engaging part and the slot. Utilizing the adhesive's bonding properties, chemical bonds or intermolecular forces are formed on both surfaces, further enhancing the connection strength. Simultaneously, the mechanical snap-fit ​​structure ensures rapid initial positioning of the upper and lower frames 140, maintaining stable contact during the adhesive curing process and preventing relative displacement from affecting the bonding effect.

[0058] This composite connection method combines the advantages of mechanical restraint and chemical bonding. The mechanical locking part, through the cooperation of the second locking groove 148 and the second locking part 158, provides initial connection rigidity and resistance to external forces, restricting the relative movement of the upper and lower frames 140; while the adhesive, through molecular-level bonding force, fills the tiny gaps that the mechanical structure cannot eliminate, eliminating the risk of loosening caused by tolerances, and evenly distributing stress when subjected to external forces, avoiding local stress concentration. The synergistic effect of both allows the connection part to rely on the rigid support of the mechanical structure when subjected to external forces such as tension and torsion, while also preventing interface separation with the adhesive effect of the adhesive, significantly improving the overall fatigue resistance and environmental adaptability of the frame.

[0059] Meanwhile, the use of adhesives did not significantly increase the complexity of assembly. Only a simple adhesive application step was added to the original mechanical assembly process to improve the connection performance, thus balancing production efficiency and product quality.

[0060] See Figures 4 to 8 In one embodiment, at least one positioning post 149 is provided on the bottom wall of the first mounting groove 141, and the positioning post 149 is provided with a first positioning hole 1491. At least one mounting post 159 is provided on the third mounting groove 151, and the mounting post 159 is inserted into the positioning hole.

[0061] In this embodiment, in order to further improve the positioning accuracy and structural stability during the assembly process of the magnetic panel, a positioning post 149 and a mounting post 159 are provided between the first mounting groove 141 and the third mounting groove 151 to achieve precise alignment and reliable connection of the upper and lower frames 140 during splicing, thereby solving the problems of magnetic component 120 offset and structural loosening caused by assembly errors.

[0062] See Figures 4 to 8 In one embodiment, at least one first reinforcing rib 1411 is also provided on the inner wall of the first mounting groove 141.

[0063] In this embodiment, considering that the first mounting groove 141 needs to withstand the compression of the magnetic component 120 and the splicing force during the use of the magnetic panel, at least one first reinforcing rib 1411 is provided on the inner wall of the first mounting groove 141 to enhance its structural strength and deformation resistance, thereby improving the overall mechanical performance and reliability of the frame body 100. Specifically, the first reinforcing rib 1411 extends along the inner wall of the first mounting groove 141, and its cross-sectional shape can be designed as a triangle, rectangle, or other structure according to mechanical requirements. During assembly, the first reinforcing rib 1411 is integrally formed with the lower frame 140, allowing the reinforcing rib to fit tightly against the inner wall of the first mounting groove 141. When the magnetic component 120 is installed in the first receiving space 110 formed by the first mounting groove 141 and the third mounting groove 151, external forces will also be transmitted to the mounting groove through the magnetic component 120 during the splicing of the magnetic panel. At this time, the first reinforcing rib 1411, by virtue of its own structural characteristics, disperses the concentrated stress to the entire mounting groove wall. The reinforcing ribs alter the stress distribution in the mounting groove, increasing the moment of inertia in local areas, thereby improving the bending stiffness and compressive strength of the groove wall and effectively suppressing the deformation of the mounting groove caused by stress.

[0064] See Figures 4 to 8 In one embodiment, at least one second reinforcing rib 1412 is provided on the inner wall of the first mounting groove 141. One end of the second reinforcing rib is connected to the positioning post 149, and the other end of the second reinforcing rib is connected to the first reinforcing rib 1411.

[0065] In this embodiment, in order to further improve the overall mechanical performance of the first mounting groove 141 and enhance the stability of the frame body 100 when bearing the magnetic suction component 120 and withstanding splicing external forces, a second reinforcing rib 1412 is set and a connection structure is constructed between it and the positioning post 149 and the first reinforcing rib 1411. This aims to solve problems such as mounting groove deformation and structural failure caused by local stress concentration, thereby forming a more complete mechanical support system.

[0066] In terms of specific construction, at least one second reinforcing rib 1412 is provided on the inner wall of the first mounting groove 141. One end of the second reinforcing rib is firmly connected to the positioning post 149, and the other end is connected to the first reinforcing rib 1411, forming a three-dimensional reinforcing network structure. The second reinforcing rib 1412 and the lower frame 140 are manufactured using an integral molding process to ensure connection strength. When the magnetic panel is in use, the magnetic force generated by the magnetic component 120 and the external force during splicing act on the first mounting groove 141. At this time, the second reinforcing rib 1412 works together with the first reinforcing rib 1411 and the positioning post 149. The second reinforcing rib 1412, through its connection with the positioning post 149, disperses and transmits the axial force and shear force on the positioning post 149; at the same time, its connection with the first reinforcing rib 1411 further strengthens the overall rigidity of the mounting groove wall, so that the stress can be evenly distributed throughout the entire reinforcing rib network. This multi-component collaborative structural design changes the traditional mode of a single reinforcing rib only locally strengthening the groove wall, constructing a three-dimensional mechanical support structure, which greatly improves the ability of the first mounting groove 141 to resist deformation.

[0067] During use, even if the magnetic panel is subjected to significant external impact or prolonged use, the first mounting groove 141, due to the presence of a reinforcing rib network, can effectively limit deformation and ensure the stability of the magnetic component 120's mounting position. This also enhances the overall fatigue resistance of the frame and extends the service life of the magnetic panel.

[0068] See Figures 4 to 8 In one embodiment, at least one third reinforcing rib 1511 is also provided on the inner wall of the second mounting groove 142.

[0069] In one embodiment, at least one fourth reinforcing rib 1512 is provided on the inner wall of the second mounting groove 142. One end of the fourth reinforcing rib is connected to the mounting post 159, and the other end of the fourth reinforcing rib is connected to the third reinforcing rib 1511.

[0070] It is understandable that the reinforcing ribs on the upper frame 150 and the lower frame 140 are based on the same principle, which will not be elaborated here.

[0071] See Figures 4 to 8 In one embodiment, the second mounting groove 142 is provided with at least one first positioning block 1421, which is used to cooperate with the second positioning hole 210 on the baffle 200 to fix the baffle 200.

[0072] In this embodiment, in order to further improve the installation accuracy and fixing effect of the baffle 200 within the limiting space 130 and solve the problem of easy displacement and installation deviation of the baffle 200 in the traditional assembly method, a first positioning block 1421 is set on the second mounting groove 142 and made to cooperate with the second positioning hole 210 on the baffle 200, so as to achieve accurate and stable positioning and fixing of the baffle 200.

[0073] In terms of specific construction, at least one first positioning block 1421 is provided on the inner wall of the second mounting groove 142. The shape and size of the positioning block are adapted to the second positioning hole 210 on the baffle 200. During assembly, the baffle 200 is placed in the second mounting groove 142, at which time the first positioning block 1421 can be accurately embedded in the second positioning hole 210. Its principle is based on the positioning pin principle in mechanical assembly. By utilizing the interference fit or transition fit between the first positioning block 1421 and the second positioning hole 210, the horizontal movement of the baffle 200 within the limiting space 130 is restricted. The first positioning block 1421 not only plays a positioning role, but also undertakes the function of transmitting external forces during the splicing process to a certain extent. By distributing the insertion and extraction forces, extrusion forces, etc., on the baffle 200 to the wall of the second mounting groove 142, the baffle 200 is prevented from deforming or loosening due to uneven force.

[0074] In actual assembly, the cooperation between the first positioning block 1421 and the second positioning hole 210 greatly simplifies the installation process of the baffle 200. Operators only need to align the second positioning hole 210 on the baffle 200 with the first positioning block 1421 to quickly complete the initial positioning. Then, the upper frame 150 and lower frame 140 are spliced ​​together. The entire assembly process is simple and precise. This positioning and cooperation structure significantly improves the structural stability of the magnetic panel. Tests show that the assembled baffle 200, when subjected to conventional splicing forces, exhibits displacement within a very small range. Compared to panels without a positioning structure, its resistance to loosening is increased by approximately 50%. Simultaneously, precise positioning ensures the flatness and consistency of adjacent magnetic panels during splicing, effectively improving the overall quality and user experience of the magnetic panel splicing toy 300, and ensuring that the product maintains good performance throughout long-term use.

[0075] See Figures 4 to 8 In one embodiment, the fourth mounting groove 152 is provided with at least one second positioning block 1521, which is used to cooperate with the second positioning hole 210 on the baffle 200 to fix the baffle 200.

[0076] It is understandable that the positioning blocks mentioned above are set on the upper frame 150 and the lower frame 140 based on the same principle, which will not be elaborated here.

[0077] See Figures 4 to 8In one embodiment, the first mounting portion 143 and the first sidewall 144 have a smooth transition.

[0078] See Figures 4 to 8 In one embodiment, the second mounting portion 153 and the third sidewall 154 have a smooth transition.

[0079] See Figures 4 to 8 In one embodiment, the ends of the side edges of the frame are rounded.

[0080] To improve the safety and manufacturing rationality of the magnetic panel frame, and addressing the issues of sharp corners causing impact damage and stress concentration in traditional frame structures, the structural details of the frame body 100 are optimized by rounding the transitions between the first mounting part 143 and the first side wall 144, the second mounting part 153 and the third side wall 154, and the edge ends of the frame. This design not only effectively avoids safety hazards during use but also improves the product's mechanical properties and its compatibility with manufacturing processes.

[0081] In terms of specific construction, the connection between the first mounting part 143 and the first side wall 144, and the connection between the second mounting part 153 and the third side wall 154, are all achieved with rounded corners to achieve a smooth transition. The ends of the side edges of the frame are also processed into rounded corners. In actual processing, rounded corner molds can be set during injection molding, or rounded corners can be applied after the metal frame is machined, so that the transitions between each part form a continuous and smooth curved surface. From a mechanical point of view, sharp corners are prone to stress concentration under stress, while the smooth transition design effectively disperses the external force by increasing the stress-bearing area and eliminating abrupt interfaces, reducing the risk of material cracking. For example, when the frame is subjected to external collision or compression, the rounded corner structure can evenly transmit stress along the curved surface, avoiding structural damage caused by local overload and enhancing the overall impact resistance of the frame.

[0082] In practical applications, the rounded transitions significantly enhance product safety. For the 300 children's magnetic building block toy, this design eliminates the risk of scratches and bumps from sharp edges, meeting children's safety standards. Simultaneously, this design optimizes the assembly process. During the assembly of the upper and lower frames (140mm), the rounded transitions reduce interference caused by burrs or sharp edges, resulting in smoother component fit and improved assembly efficiency and yield. Furthermore, from an aesthetic perspective, the rounded corners create smoother and more aesthetically pleasing lines, enhancing the overall quality and market competitiveness of the product, thus balancing functionality and aesthetics.
