Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a strength-enhanced sheet metal structure and electrical appliance. Background Technology

[0002] In existing technologies, the outer casing and many internal supporting structures of home appliances are mostly made of sheet metal parts, which are particularly widely used in the field of small appliances. From a cost control perspective, some parts or casing designs use thinner sheet metal parts, which not only reduces costs but also improves processing convenience. However, parts made of thin sheet metal are very prone to deformation or even damage during subsequent processing. Especially in the later stages of surface treatment, packaging, transportation, and assembly, the bent parts are easily deformed after being squeezed, resulting in abnormal part shapes, inability to assemble properly, and ultimately waste of parts. Utility Model Content

[0003] Therefore, it is necessary to provide a strength-enhanced sheet metal structure and electrical components to address the problem of easy deformation of sheet metal parts.

[0004] A strength-enhanced sheet metal structure includes: a bending base plate; a bending assembly disposed on the bending base plate, wherein the connection between the bending assembly and the bending base plate forms an angle; and a structural reinforcement member disposed on the bending base plate and the bending assembly and located at the angle formed by the connection between the bending base plate and the bending assembly, wherein the structural reinforcement member protrudes toward the opening direction of the angle formed by the connection between the bending base plate and the bending assembly.

[0005] The above-disclosed structure is a strength-enhanced sheet metal structure. In electrical product manufacturing, sheet metal parts are widely used for housings and internal supports. Due to cost considerations, thin sheet metal parts are often chosen, which have the advantages of convenient processing and low cost, but subsequent processing can easily cause deformation problems. The strength-enhanced sheet metal structure cleverly constructs a system composed of a bending base plate, bending components, and structural reinforcements. The bending base plate and bending components form the basic shape, while the key structural reinforcement is located at the angle where the two meet and protrudes in the direction of the opening. The structural reinforcement utilizes the inherent stability characteristics of triangles to efficiently disperse stress at the bending points. In the surface treatment stage of electrical production, whether it is the thermal stress from spraying or the external impact from processes such as electroplating, the structural reinforcement can effectively resist it, significantly reducing the probability of sheet metal deformation. During the packaging and transportation stage, facing the bumps and stacking pressure during the journey, the structural reinforcement can strengthen the damage resistance of the bending points and maintain the shape of the sheet metal. In the assembly process, the structural reinforcement improves the rigidity of the sheet metal, reducing the situation where deformation due to external forces makes it unsuitable for assembly, thereby reducing the scrap rate of parts and saving production costs. Furthermore, this structure does not require a significant increase in sheet metal thickness, nor does it introduce overly complex processing procedures. While ensuring strength and quality stability, it also takes into account cost control and ease of processing, helping electrical products achieve cost reduction and efficiency improvement goals. From a production efficiency perspective, it reduces the time and material losses caused by rework and scrapping of deformed parts.

[0006] In one embodiment, there are multiple structural reinforcements, spaced apart on the bending base plate and the bending assembly. These reinforcements are located at the angle formed by the connection between the bending base plate and the bending assembly and protrude towards the opening direction of the angle. By using multiple structural reinforcements spaced apart on the bending base plate and the bending assembly, in electrical applications where cost considerations dictate the cost-effectiveness of thin sheet metal parts, the bending portion is prone to deformation due to external forces during surface treatment, transportation, and assembly. The multiple structural reinforcements distributed at the angle connecting the bending base plate and the bending assembly, protruding towards the opening direction, utilize the stable triangular structure to disperse the stress borne at the bending point from multiple points and in all directions. Whether it's the thermal stress impact during surface treatment, the bumps and squeezing during transportation, or the external forces during assembly, these structural reinforcements can strengthen and fix the bent parts of the sheet metal from different positions, fill the gaps in the strength of thin sheet metal, effectively resist the risk of deformation, significantly improve the stability and reliability of sheet metal bending strength, reduce the scrapping of parts due to bending deformation, and ensure that electrical sheet metal parts maintain good shape and performance throughout their entire life cycle.

[0007] In one embodiment, the structural reinforcement has an inner reinforcing surface and an outer reinforcing surface. The inner reinforcing surface is disposed on the bending base plate and the bending assembly, located in the opening direction of the angle formed by the connection of the bending base plate and the bending assembly. The outer reinforcing surface is disposed on the bending base plate and the bending assembly, located in the opening direction away from the angle formed by the connection of the bending base plate and the bending assembly. By positioning the inner reinforcing surface in the opening direction of the angle between the bending base plate and the bending assembly, it can directly bear external forces from the opening direction. Utilizing its adhesion to the sheet metal, it disperses and transmits the force to the bending base plate and the bending assembly, suppressing the deformation tendency at the opening caused by external forces. The outer reinforcing surface, located on the side away from the opening, provides support to the bending portion from the opposite direction, and together with the inner reinforcing surface, constructs a bidirectional force balance system. The two work together to strengthen the structural strength at the connection angle between the bending base plate and the bending component from different directions, effectively resisting external forces during surface treatment, transportation, and assembly, reducing the probability of deformation at the bending parts of thin sheet metal, ensuring the stability of the sheet metal parts' shape and performance, improving product quality and reliability, reducing the scrap of parts due to deformation, and helping electrical products achieve cost reduction and efficiency improvement.

[0008] In one embodiment, the reinforced inner surface includes a transition connecting surface, a first reinforced inner surface, and a second reinforced inner surface. A first end of the transition connecting surface is disposed on the bending base plate, and a second end of the transition connecting surface is disposed on the bending assembly. The first ends of both the first and second reinforced inner surfaces are disposed on the transition connecting surface and located on opposite sides of it. The second ends of both the first and second reinforced inner surfaces are disposed on the bending base plate, and the third ends of both the first and second reinforced inner surfaces are disposed on the bending assembly. By subdividing the reinforced inner surface into a transition connecting surface, a first reinforced inner surface, and a second reinforced inner surface, the transition connecting surface serves as a basic connecting component, with its two ends fixed to the bending base plate and the bending assembly, respectively, thus constructing an initial connection frame for the structural reinforcement at the bending angle. The first and second reinforced inner surfaces rely on the transition connecting surface, with one end converging at the transition connecting surface and positioned on either side, while the other two ends extend towards and are fixed to the bending base plate and the bending assembly, respectively. In this layout, the first and second reinforcing inner surfaces form a triangular support system. When the sheet metal bending area is subjected to thermal stress from surface treatment, transportation bumps, or assembly forces, the two surfaces can disperse and transmit the force along their own surface structure to the bending base plate and bending component. Compared to a single planar structure, the double inner surface design increases the force transmission path and load-bearing area. By utilizing the synergistic effect between the surfaces, it strengthens the support efficiency at the bending angle and effectively resists deformation. Especially in thin sheet metal applications, it can compensate for the strength shortcomings caused by insufficient material thickness. Through precise structural distribution, it improves the overall rigidity and stability of the bending area, ensuring that the sheet metal parts maintain their shape and performance throughout their entire life cycle, reducing the occurrence of scrap due to deformation, and laying a solid structural foundation for the reliable assembly and long-term use of electrical products, helping to achieve the dual goals of cost reduction, efficiency improvement, and quality enhancement.

[0009] In one embodiment, the reinforcing outer surface includes a first reinforcing outer surface and a second reinforcing outer surface. A first end of the first reinforcing outer surface is connected to a first end of the second reinforcing outer surface. A second end of the first reinforcing outer surface and a second end of the second reinforcing outer surface are disposed on the bending base plate. A third end of the first reinforcing outer surface and a third end of the second reinforcing outer surface are disposed on the bending assembly. The first and second reinforcing outer surfaces form a groove. By connecting the first ends of the first and second reinforcing outer surfaces, fixing their second ends together on the bending base plate, and disposing their third ends together on the bending assembly, this connection method creates a stable integral structure that effectively supports the bending portion from the side away from the bending angle opening. Simultaneously, the groove formed by the two surfaces optimizes the force transmission path. When the bending portion is subjected to external force, the first and second reinforcing outer surfaces can distribute the force to the bending base plate and the bending assembly, reducing local stress concentration. For thin sheet metal parts, this structure can compensate for the strength defects caused by their insufficient thickness. In the process of surface treatment, transportation and assembly, it can effectively resist external forces that may deform the bending parts, further improve the overall rigidity and deformation resistance of the sheet metal bending parts, and work together with the reinforced inner surface to strengthen the structure from different directions, reduce the probability of parts being scrapped due to deformation, and ensure the stable application of sheet metal parts in electrical products.

[0010] In one embodiment, the first reinforcing inner surface, the second reinforcing inner surface, the first reinforcing outer surface, and the second reinforcing outer surface are all triangular. By designing the first reinforcing inner surface, the second reinforcing inner surface, the first reinforcing outer surface, and the second reinforcing outer surface as triangles, this design fully utilizes the inherent stability characteristics of triangular structures, significantly enhancing the overall strength of the bent sheet metal. From a mechanical perspective, triangles are immutable and do not easily change shape under external forces. Designing these four surfaces as triangles allows them to form stable force-bearing units in their respective positions. The first and second reinforcing inner surfaces, as important components of the reinforcing inner surface, function in the direction of the bending angle opening with their triangular structures. This allows for more efficient dispersion of external forces from the opening direction, further strengthening the support for the inner side of the bending portion and suppressing the deformation tendency at the opening. The first and second reinforcing outer surfaces, also with triangular structures, work together on the side away from the opening. The grooves they form, combined with the stability of the triangle, optimize the resistance to reverse external forces, making the force transmission more uniform and reducing local stress concentration. These four triangular faces work together to provide three-dimensional stable support at the angle formed by the connection between the bent base plate and the bent component from different internal and external directions. Compared with other shapes, this can more effectively compensate for the lack of thickness in thin sheet metal parts, and significantly improve the deformation resistance of the bent parts in the process of surface treatment, transportation, and assembly.

[0011] In one embodiment, there are multiple bending components, which are arranged circumferentially along the bending base plate and each forms an angle with the connection point of the bending base plate. By arranging multiple bending components circumferentially along the bending base plate and forming angles with the connection point of the bending base plate, this design can significantly improve the applicability and stability of sheet metal structures in electrical products. From a structural perspective, the multiple bending components distributed circumferentially can form a three-dimensional frame with a certain degree of enclosure or semi-enclosure together with the bending base plate, which can better adapt to the complex spatial layout inside electrical appliances, providing surrounding mounting positions and support points for various components, and meeting the needs of multi-component collaborative assembly. At the same time, the angle formed by each bending component and the bending base plate, combined with the function of structural reinforcement, can form independent stress support units in different circumferential directions. When the overall structure is subjected to external forces from different directions, the multiple bending components can work together to disperse stress, avoiding deformation of a single part due to stress concentration.

[0012] In one embodiment, the bending assembly includes a bending body and a bending transition member. One end of the bending transition member is disposed on the bending body, and the other end of the bending transition member, away from the bending body, is disposed at the bending base plate. An angle is formed between the bending transition member and the bending base plate. By using the bending transition member as an intermediate structure connecting the bending body and the bending base plate, the force transmission path can be optimized. When an external force is applied to the bending body, the force can be gradually transmitted to the bending base plate through the bending transition member, avoiding direct force application at the connection point and causing local stress concentration. Especially for thin sheet metal parts, this reduces deformation or damage caused by stress concentration and enhances the overall structural stress balance. On the other hand, the angle formed between the bending transition member and the bending base plate, combined with the structure of the bending transition member, provides a more stable support foundation for the bending body. Compared to the bending body being directly connected to the bending base plate, the presence of the bending transition piece makes the connection between the bending body and the bending base plate more in line with mechanical requirements, improves the positional stability of the bending component when it is distributed in the circumferential direction, and ensures that it is not easy to shift when subjected to external forces.

[0013] In one embodiment, the bending base plate, the bending assembly, and the structural reinforcement are integrally formed. By integrally forming the bending base plate, the bending assembly, and the structural reinforcement, gaps or weak points that may arise from splicing or welding between components are avoided. This allows the bending base plate, the bending assembly, and the structural reinforcement to form a continuous whole, ensuring smoother and more even force transmission between the parts and reducing stress concentration caused by connection problems. Under stress, external forces can be dispersed to a larger area through the overall structure, rather than being limited to local connection points, thereby further improving the deformation resistance of the entire sheet metal structure.

[0014] In one embodiment, the angle between the bending component and the bending base plate is greater than 0° and less than 180°. By setting the angle between the bending component and the bending base plate to be greater than 0° and less than 180°, a non-parallel and non-overlapping connection is formed between the bending component and the bending base plate, enabling the construction of a three-dimensional structure that meets the internal spatial layout and external form requirements of electrical products, and satisfying the functional requirements of installation, support, and protection for different components.

[0015] The second aspect of this application discloses an electrical appliance, which includes: the aforementioned strength-enhancing sheet metal structure; and an electrical appliance body, wherein the strength-enhancing sheet metal structure is disposed on the electrical appliance body.

[0016] The second aspect disclosed above discloses an electrical appliance that, through the synergistic effect of a bending base plate, bending components, and structural reinforcements, especially the three-dimensional support of multiple triangular reinforcing surfaces and the stability of integrated molding, can strengthen the overall rigidity of the appliance's outer shell or internal support structure. This effectively resists external forces such as collisions and compression during daily use and transportation, reducing damage to the appliance body caused by sheet metal deformation. From a performance stability perspective, this structure reduces the probability of sheet metal deformation during long-term use, ensures the relative positional stability of internal components, reduces problems such as poor circuit contact and component jamming caused by structural deformation, and guarantees the normal operation of the appliance.

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] The following description, with reference to the accompanying drawings, describes some embodiments of the strength-enhanced sheet metal structure and electrical components of this utility model.

[0033] Example 1

[0034] like Figures 1 to 9 As shown, this embodiment discloses a strength-enhanced sheet metal structure, including: a bending base plate 1; a bending component 2, which is disposed on the bending base plate 1, and the connection between the bending component 2 and the bending base plate 1 forms an angle; and a structural reinforcement 3, which is disposed on the bending base plate 1 and the bending component 2 and located at the angle formed by the connection between the bending base plate 1 and the bending component 2, and the structural reinforcement 3 protrudes toward the opening direction of the angle formed by the connection between the bending base plate 1 and the bending component 2.

[0035] This application discloses a strength-enhanced sheet metal structure. In the manufacturing of electrical products, sheet metal parts are widely used for housings and internal supports. Due to cost considerations, thin sheet metal parts are often chosen. Although they have the advantages of convenient processing and low cost, subsequent processing can easily cause deformation problems. The strength-enhanced sheet metal structure cleverly constructs a system composed of a bending base plate 1, a bending component 2, and a structural reinforcement 3. The bending base plate 1 and the bending component 2 form the basic shape, while the key structural reinforcement 3 is set at the angle where the two are connected and protrudes in the direction of the opening. The structural reinforcement 3 utilizes the inherent stability characteristics of a triangle to efficiently disperse the stress at the bending part. In the surface treatment stage of electrical appliance manufacturing, the structural reinforcement component 3 effectively resists both the thermal stress from spraying and the external impact from processes such as electroplating, significantly reducing the probability of sheet metal deformation. During the packaging and transportation stage, facing bumps and stacking pressure, the structural reinforcement component 3 strengthens the damage resistance of bending areas, maintaining the sheet metal shape. In the assembly process, the structural reinforcement component 3 improves the rigidity of the sheet metal, reducing the likelihood of deformation due to external forces preventing proper assembly, thereby reducing the scrap rate and saving production costs. Furthermore, this structure does not require a significant increase in sheet metal thickness or the introduction of overly complex processing steps. While ensuring strength and quality stability, it also considers cost control and ease of processing, helping electrical products achieve cost reduction and efficiency improvement goals. From a production efficiency perspective, it reduces the time and material losses caused by rework and scrap due to part deformation.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of structural reinforcement members 3 is multiple, and the multiple structural reinforcement members 3 are spaced apart on the bending base plate 1 and the bending assembly 2. The multiple structural reinforcement members 3 are located at the angle formed by the connection between the bending base plate 1 and the bending assembly 2 and protrude in the direction of the opening of the angle. By using multiple structural reinforcement members 3 spaced apart on the bending base plate 1 and the bending assembly 2, in electrical applications, thin sheet metal parts used for cost considerations are prone to deformation due to external forces during surface treatment, transportation, assembly, and other processes when bending. However, the multiple structural reinforcement members 3 are distributed at the angle where the bending base plate 1 and the bending assembly 2 are connected and protrude in the direction of the opening. With the help of the stable triangular structure characteristics, the stress borne by the bending point can be distributed in multiple points and in all directions. Whether it's the thermal stress impact during surface treatment, the bumps and squeezing during transportation, or the external forces during assembly, these structural reinforcements 3 can strengthen and fix the bent parts of the sheet metal from different positions, fill the gaps in the strength of the thin sheet metal itself, effectively resist the risk of deformation, significantly improve the stability and reliability of the sheet metal bending strength, reduce the scrapping of parts due to bending deformation, and ensure that electrical sheet metal parts maintain good shape and performance throughout the entire life cycle.

[0037] like Figure 1 , Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the structural reinforcement 3 has a reinforced inner surface 31 and a reinforced outer surface 32. The reinforced inner surface 31 is disposed on the bending base plate 1 and the bending assembly 2 and is located in the opening direction of the angle formed by the connection of the bending base plate 1 and the bending assembly 2. The reinforced outer surface 32 is disposed on the bending base plate 1 and the bending assembly 2 and is located in the opening direction away from the angle formed by the connection of the bending base plate 1 and the bending assembly 2. By placing the reinforced inner surface 31 in the opening direction of the connection angle of the bending base plate 1 and the bending assembly 2, it can directly bear the external force from the opening direction. By utilizing its own adhesion to the sheet metal, it disperses and transmits the force to the bending base plate 1 and the bending assembly 2, suppressing the deformation tendency caused by external force at the opening. The reinforced outer surface 32 is located on the side away from the opening, forming support for the bending part from the opposite direction. It cooperates with the reinforced inner surface 31 to construct a two-way force balance system. The two work together to strengthen the structural strength at the connection angle between the bending base plate 1 and the bending component 2 from different directions, effectively resisting external forces during surface treatment, transportation, and assembly, reducing the probability of deformation at the bending parts of thin sheet metal, ensuring the stability of the sheet metal parts' shape and performance, improving product quality and reliability, reducing the scrap of parts due to deformation, and helping electrical products achieve cost reduction and efficiency improvement.

[0038] like Figure 1 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the reinforced inner surface 31 includes a transition connecting surface 311, a first reinforced inner surface 312, and a second reinforced inner surface 313. The first end of the transition connecting surface 311 is disposed on the bending base plate 1, and the second end of the transition connecting surface 311 is disposed on the bending assembly 2. The first ends of the first reinforced inner surface 312 and the first ends of the second reinforced inner surface 313 are both disposed on the transition connecting surface 311 and located on both sides of the transition connecting surface 311. The second ends of the first reinforced inner surface 312 and the second ends of the second reinforced inner surface 313 are disposed on the bending base plate 1, and the third ends of the first reinforced inner surface 312 and the third ends of the second reinforced inner surface 313 are disposed on the bending assembly 2. By subdividing the reinforced inner surface 31 into the transition connecting surface 311, the first reinforced inner surface 312, and the second reinforced inner surface 313, the transition connecting surface 311 serves as a basic connecting component, with its two ends respectively fixed to the bending base plate 1 and the bending assembly 2, thus constructing the initial connection frame of the structural reinforcement 3 at the bending angle. The first reinforcing inner surface 312 and the second reinforcing inner surface 313 rely on the transition connecting surface 311. They meet at one end of the transition connecting surface 311 and are positioned on opposite sides, while the other two ends extend towards and are fixed to the bending base plate 1 and the bending assembly 2, respectively. In this layout, the first reinforcing inner surface 312 and the second reinforcing inner surface 313 form a triangular support system. When the sheet metal bending area is subjected to thermal stress from surface treatment, the impact force during transportation, or external forces during assembly, the two surfaces can disperse and transmit the force along their own surface structure to the bending base plate 1 and the bending assembly 2. Compared to a single planar structure, the double inner surface design increases the force transmission path and bearing area. By utilizing the synergistic effect between the surfaces, it strengthens the support efficiency at the bending angle and effectively resists deformation tendencies. Especially in thin sheet metal applications, it can compensate for the strength deficiency caused by insufficient material thickness. Through precise structural distribution, it can improve the overall rigidity and stability of bending parts, ensure that sheet metal parts maintain their shape and performance throughout their entire life cycle, reduce the occurrence of scrap due to deformation, build a solid structural foundation for the reliable assembly and long-term use of electrical products, and help achieve the dual goals of cost reduction and efficiency improvement and quality enhancement.

[0039] like Figure 1 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the reinforcing outer surface 32 includes a first reinforcing outer surface 321 and a second reinforcing outer surface 322. The first end of the first reinforcing outer surface 321 is connected to the first end of the second reinforcing outer surface 322. The second ends of the first reinforcing outer surface 321 and the second ends of the second reinforcing outer surface 322 are disposed on the bending base plate 1. The third ends of the first reinforcing outer surface 321 and the third ends of the second reinforcing outer surface 322 are disposed on the bending assembly 2. The first reinforcing outer surface 321 and the second reinforcing outer surface 322 form a groove 301. By connecting the first ends of the first reinforcing outer surface 321 and the second reinforcing outer surface 322, fixing the second ends together on the bending base plate 1, and disposing the third ends together on the bending assembly 2, this connection method enables the two to form a stable overall structure, which can effectively support the bending part from the side away from the bending angle opening. At the same time, the groove 301 formed by the two can optimize the force transmission path. When the bending part is subjected to external force, the first reinforcing outer surface 321 and the second reinforcing outer surface 322 can distribute the force to the bending base plate 1 and the bending assembly 2, reducing local stress concentration. For thin sheet metal parts, this structure can compensate for the strength defects caused by their insufficient thickness. In the process of surface treatment, transportation and assembly, it can effectively resist external forces that may deform the bending parts, further improve the overall rigidity and deformation resistance of the sheet metal bending parts, and work together with the reinforced inner surface 31 to strengthen the structure from different directions, reduce the probability of parts being scrapped due to deformation, and ensure the stable application of sheet metal parts in electrical products.

[0040] like Figures 6 to 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first reinforcing inner surface 312, the second reinforcing inner surface 313, the first reinforcing outer surface 321, and the second reinforcing outer surface 322 are all triangular. By setting the first reinforcing inner surface 312, the second reinforcing inner surface 313, the first reinforcing outer surface 321, and the second reinforcing outer surface 322 as triangular, this design fully utilizes the inherent stability characteristics of the triangular structure, which can significantly enhance the overall strength of the bent sheet metal. From a mechanical point of view, triangles are immutable and do not easily change shape under external force. Designing these four surfaces as triangles allows them to form stable force-bearing units in their respective positions. The first reinforcing inner surface 312 and the second reinforcing inner surface 313, as important components of the reinforcing inner surface 31, function in the direction of the opening at the bending angle with a triangular structure, which can more efficiently disperse the external force from the opening direction, further strengthen the support for the inner side of the bending part, and suppress the deformation tendency at the opening. The first reinforcing outer surface 321 and the second reinforcing outer surface 322 also work together in a triangular structure on the side away from the opening. The groove 301 they form, combined with the stability of the triangle, optimizes the resistance to reverse external forces, making the force transmission more uniform and reducing local stress concentration. These four triangular surfaces cooperate with each other to form a three-dimensional stable support at the angle formed by the connection between the bending base plate 1 and the bending component 2 from different internal and external directions. Compared with other shapes, it can more effectively make up for the defects of insufficient thickness of thin sheet metal parts, and significantly improve the deformation resistance of the bending part in the process of surface treatment, transportation, and assembly.

[0041] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of bending components 2 is multiple, and the multiple bending components 2 are arranged circumferentially along the bending base plate 1 and all form an angle with the connection point of the bending base plate 1. By arranging multiple bending components 2 circumferentially along the bending base plate 1 and forming an angle with the connection point of the bending base plate 1, this design can significantly improve the applicability and stability of sheet metal structures in electrical products. From a structural perspective, the multiple bending components 2 are distributed circumferentially and can form a three-dimensional frame with a certain degree of enclosure or semi-enclosure together with the bending base plate 1, which can better adapt to the complex spatial layout inside electrical appliances, provide surrounding mounting positions and support points for various components, and meet the needs of multi-component collaborative assembly. At the same time, the angle formed by each bending component 2 and the bending base plate 1, combined with the function of the structural reinforcement 3, can form an independent force-bearing support unit in different circumferential directions. When the overall structure is subjected to external forces from different directions, the multiple bending components 2 can work together to disperse stress and avoid deformation of a single part due to force concentration.

[0042] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines that: the bending assembly 2 includes a bending body 21 and a bending transition piece 22. One end of the bending transition piece 22 is disposed on the bending body 21, and the other end of the bending transition piece 22 away from the bending body 21 is disposed at the bending base plate 1, forming an angle between the bending transition piece 22 and the bending base plate 1. By using the bending transition piece 22 as an intermediate structure connecting the bending body 21 and the bending base plate 1, the force transmission path can be optimized. When an external force is applied to the bending body 21, the force can be gradually transmitted to the bending base plate 1 through the bending transition piece 22, avoiding the force from acting directly on the connection point and causing local stress concentration. Especially for thin sheet metal parts, this can reduce deformation or damage caused by stress concentration and enhance the stress balance of the overall structure. On the other hand, the angle formed between the bending transition piece 22 and the bending base plate 1, combined with the structure of the bending transition piece 22, can provide a more stable support foundation for the bending body 21. Compared to the bending body 21 being directly connected to the bending base plate 1, the presence of the bending transition piece 22 makes the connection between the bending body 21 and the bending base plate 1 more in line with mechanical requirements, improves the positional stability of the bending component 2 when it is distributed in the circumferential direction, and ensures that it is not easy to deviate when subjected to external forces.

[0043] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the bending base plate 1, the bending assembly 2, and the structural reinforcement 3 are integrally formed. By integrally forming the bending base plate 1, the bending assembly 2, and the structural reinforcement 3, gaps or weak points that may occur when connecting the components through splicing, welding, or other methods are avoided. This allows the bending base plate 1, the bending assembly 2, and the structural reinforcement 3 to form a continuous whole, ensuring that force can be transmitted more smoothly and evenly between the parts and reducing stress concentration caused by connection problems. When under stress, external forces can be dispersed to a larger area through the overall structure, rather than being limited to local connection points, thereby further improving the deformation resistance of the entire sheet metal structure.

[0044] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the angle formed between the bending component 2 and the bending base plate 1 is greater than 0° and less than 180°. By setting the angle between the bending component 2 and the bending base plate 1 to be greater than 0° and less than 180°, the bending component and the bending base plate 1 form a non-parallel and non-overlapping connection relationship, which can construct a three-dimensional structure that meets the internal spatial layout and external shape requirements of electrical products, and satisfy the functional requirements of installation, support and protection of different components.

[0045] Example 2

[0046] like Figures 1 to 9As shown, this embodiment discloses an electrical appliance, which includes: the aforementioned strength-enhancing sheet metal structure; and an electrical appliance body, wherein the strength-enhancing sheet metal structure is disposed on the electrical appliance body.

[0047] The second aspect of this application discloses an electrical appliance that, through the synergistic effect of a bending base plate 1, a bending component 2, and a structural reinforcement 3, particularly the three-dimensional support of multiple triangular reinforcing surfaces and the stability of the integral molding, can strengthen the overall rigidity of the appliance's outer shell or internal support structure. This effectively resists external forces such as collisions and compression during daily use and handling, reducing damage to the appliance body caused by sheet metal deformation. From a performance stability perspective, this structure reduces the probability of sheet metal deformation during long-term use, ensures the relative position stability of various components inside the appliance, reduces problems such as poor circuit contact and component jamming caused by structural deformation, and guarantees the normal operation of the appliance.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
