Description

TECHNICAL FIELD

[0001] The utility model relates to the field of household appliances, in particular to a deformation prevention structure and electric appliance. BACKGROUND

[0002] The current household appliance products on the market adopt plastic structural parts for shell appearance parts, and have high appearance requirements. However, many products place the screw column on a surface with large slope when designing the internal structure. In this way, the glue at the bottom of the screw column is easy to coincide with the glue position of the main wall of the product, causing the local glue position to be too thick, which causes the deformation and shrinkage of the outer side of the product, which obviously violates the design principle of uniform main wall of the plastic part. SUMMARY

[0003] Therefore, it is necessary to provide a deformation prevention structure and electric appliance for the problem of excessive glue position at the connecting part of the connecting part of the household appliance shell.

[0004] A deformation prevention structure, the deformation prevention structure comprises: a shell assembly, the shell assembly is provided with a containing cavity; a fixed base assembly, the fixed base assembly is arranged on the shell assembly and located in the containing cavity, the thickness of the contact end surface of the fixed base assembly and the shell assembly is less than half of the thickness of the shell assembly, the fixed base assembly is provided with an opening; a connecting column, the connecting column is arranged on the fixed base assembly, and the connecting column is used for connecting with an external structure.

[0005] The above discloses a deformation prevention structure, first, the shell assembly is provided with a containing cavity, which builds a reasonable placement space for the entire internal structure, so that the components are orderly arranged, and the coordination of the overall structure is ensured. The thickness of the contact end surface of the fixed base assembly and the shell assembly is much smaller than the thickness of the shell assembly, which is a clever solution to the key problem of shrinkage of the shell surface. In the design of the plastic appearance part of the household appliance product commonly seen in the past, due to the unreasonable internal structure, the glue position of the screw column and other parts is easy to overlap with the main wall of the product, and the local glue position is too thick, which violates the principle of uniformity of the main wall of the plastic part, and further causes the surface deformation and shrinkage of the shell assembly, which seriously affects the appearance quality of the electric appliance. The thickness of the fixed base assembly and the shell assembly is controlled, which effectively avoids the overlapping of the glue position, so that the shell assembly can always maintain a good appearance state, perfectly matching those household appliances with high appearance requirements. The opening provided on the fixed base assembly further optimizes the rationality of the structure, further reduces the contact area of the fixed base assembly and the shell assembly, better avoids the surface deformation and shrinkage of the shell assembly, and also reduces the weight of the deformation prevention structure, making the whole electric appliance more lightweight. The setting of the connecting column on the fixed base assembly is used to connect with the external structure, which ensures stable connection and relies on the reasonable layout of the whole deformation prevention structure, without negative impact on the appearance of the shell assembly and the stability of the internal structure. In summary, this structure prevents the surface shrinkage of the shell assembly from the root, improves the overall appearance and structural reliability of the product, and has great application and promotion value.

[0006] In one embodiment, the number of fixed base assemblies is multiple, and the multiple fixed base assemblies are arranged on the shell assembly and spaced along the inner side of the shell assembly. By arranging multiple fixed base assemblies along the inner side of the shell assembly, more stable and balanced support force can be provided for the shell assembly, effectively dispersing external pressure and avoiding local deformation of the shell assembly due to excessive force on a single point, greatly enhancing the overall structural stability of the shell assembly, ensuring that the household appliance maintains good appearance integrity during long-term use, and meeting the product demand for high appearance parts. Secondly, the circumferentially spaced arrangement makes the connection points of the connecting columns and the external structure more reasonable, which can better adapt to different direction forces when assembling or connecting with other components, improving the reliability and firmness of the entire product structure, reducing the damage risk caused by improper connection, prolonging the service life of the product, improving the market competitiveness of the product, and providing users with a better use experience.

[0007] In one of the embodiments, the number of fixed base assemblies is multiple, and the number of connecting columns is multiple, and the multiple connecting columns are one-to-one corresponding to the multiple fixed base assemblies. By one-to-one corresponding the multiple fixed base assemblies to the multiple connecting columns, on the one hand, the multiple connecting points are uniformly distributed, so that the external force acting on the shell assembly can be dispersed to each fixed base assembly, avoiding stress concentration, effectively preventing the shell from deforming, ensuring the flatness and aesthetics of the product appearance, meeting the demand of household appliances with strict appearance requirements. On the other hand, the one-to-one corresponding arrangement enhances the stability and reliability of the internal structure and external connection. Whether it is the vibration in the transportation process or the collision, pulling and other situations in daily use, the overall structure can remain stable, reducing the risk of part loosening and displacement, thereby improving the durability and safety of the product, providing users with a more durable and reliable use experience, and improving the competitiveness of the product in the market.

[0008] In one of the embodiments, the fixed base assembly includes a support block assembly and a support platform, the support block assembly is arranged on the shell assembly, the support platform is arranged on the support block assembly and / or the shell assembly, and the connecting column is arranged on the support platform. The support block assembly, the support platform and the shell assembly form the opening. By using the combination of the support block assembly and the support platform, the fixed base assembly forms a stable support structure that can efficiently bear the external force transmitted by the connecting column and uniformly disperse it to the shell assembly, effectively enhancing the stability of the overall structure, preventing the shell from deforming locally, and ensuring the precision and quality of the product appearance, especially for household appliances with high appearance requirements. Secondly, the opening formed by the support block assembly, the support platform and the shell assembly not only reduces the contact area between the fixed base assembly and the shell assembly, but also reduces the risk of deformation of the shell assembly caused by stress concentration due to excessive contact area. It also reduces the weight of the anti-deformation structure, making the product more lightweight under the premise of ensuring structural strength, easy to install, transport and use, reducing transportation and labor costs, improving production efficiency and market competitiveness of the product, bringing great convenience and advantages to users and manufacturers.

[0009] In one of the embodiments, the support block assembly includes a first support block and a second support block, the first support block and the second support block are arranged opposite to each other on the shell assembly, and the support platform is arranged on the first support block and the second support block. By arranging the first support block and the second support block opposite to each other on the shell assembly, a stable support structure is formed, providing a balanced and reliable fulcrum for the support platform, effectively dispersing the external force transmitted by the connecting column, avoiding stress concentration at a certain point, thereby greatly enhancing the stability and reliability of the entire anti-deformation structure, ensuring that the shell is not easily deformed, and ensuring the quality of the product appearance.

[0010] In one of the embodiments, the first support block comprises a first shell connecting end face and a first platform connecting end face, the first shell connecting end face is arranged on the shell assembly, the first platform connecting end face is arranged on the first shell connecting end face, the support platform is arranged on the first platform connecting end face, and the thickness of the first shell connecting end face in contact with the shell assembly is less than half of the thickness of the shell assembly. By designing the thickness of the first shell connecting end face of the first support block in contact with the shell assembly to be much smaller than the thickness of the shell assembly, the purpose of preventing the surface shrinkage of the shell assembly is achieved. In the traditional design of the plastic appearance part of household appliances, the large area of the connecting part is an important reason for the problems of glue position overlapping and surface shrinkage of the shell. By reducing the contact area, the design effectively avoids the accumulation of too much glue at the connecting part, prevents the local stress change caused by uneven glue position, and greatly reduces the risk of surface shrinkage of the shell assembly, ensuring the flatness and aesthetics of the shell, and highly meeting the product demand for strict appearance quality. At the same time, it also reduces the scrap rate caused by appearance defects, improves production efficiency and product yield. In the long run, it not only reduces production cost, but also helps to improve product competitiveness and brand image in the market, providing users with household appliances with exquisite appearance and reliable quality. Moreover, compared with the traditional volcano structure, the structure of the present application ensures the structural strength of the shell assembly.

[0011] In one of the embodiments, the second support block comprises a second shell connecting end face and a second platform connecting end face, the second shell connecting end face is arranged on the shell assembly, the second platform connecting end face is arranged on the second shell connecting end face, the support platform is arranged on the second platform connecting end face, and the thickness of the second shell connecting end face in contact with the shell assembly is less than half of the thickness of the shell assembly. By designing the thickness of the second shell connecting end face of the second support block in contact with the shell assembly to be much smaller than the thickness of the shell assembly, the possibility of problems such as glue position overlapping and surface shrinkage of the shell caused by the large area of the connecting part is fundamentally reduced. In the production process of the plastic appearance part, the large connecting area is easy to cause uneven distribution of glue, leading to local glue position being too thick, and then causing the surface of the shell to shrink, which seriously affects the appearance quality and performance of the product. The design effectively avoids this risk, so that the shell can remain flat and smooth, meeting the strict requirements of high-end household appliances for exquisite appearance. Not only reduces the scrap rate and rework cost, but also improves the overall quality and market competitiveness of the product, providing users with more beautiful, durable and stable products, while ensuring the structural stability, perfectly solving the appearance defect problem in the traditional design.

[0012] In one of the embodiments, the support platform comprises a shell connecting end face arranged on the shell assembly, and the thickness of the shell connecting end face in contact with the shell assembly is less than half of the thickness of the shell assembly. By designing the thickness of the shell connecting end face in contact with the shell assembly to be much smaller than the thickness of the shell assembly, the possibility of problems such as glue position overlap and surface shrinkage of the shell assembly is greatly reduced. During the molding process of the plastic part, the smaller contact area can effectively avoid the uneven stress caused by excessive local glue, prevent the shell from deforming, sinking and other defects due to inconsistent shrinkage, ensure the flatness and aesthetics of the product appearance, and meet the product demand with high appearance requirements. Compared with the traditional crater structure, this structure will weaken the local structural strength, because it changes the original material distribution during the glue reduction process, making this part more prone to deformation or damage when subjected to external force. On the contrary, the anti-deformation structure of the present application adopts the combined design of multiple support block assemblies and support platforms, forming a stable support system that can more evenly distribute external forces, enhancing the stability and reliability of the overall structure, ensuring that the product can withstand various external forces during long-term use, reducing the risk of failure or damage due to insufficient structural strength, and prolonging the service life of the product.

[0013] In one of the embodiments, the support block assembly and the support platform are integrally formed. By integrally forming the support block assembly and the support platform, the connection gap between the components is eliminated, greatly enhancing the overall structural strength and stability, allowing it to better withstand external forces, reducing the risk of deformation due to loose connections or gaps, ensuring the accuracy and integrity of the product shell, and meeting the product demand with high appearance quality requirements. At the same time, it reduces the quality problems caused by assembly errors, improves the yield of the product, and thus enhances the market competitiveness of the product, creating more benefits for the enterprise.

[0014] In one of the embodiments, the fixed base assembly and the connecting column are integrally formed. By integrally forming the fixed base assembly and the connecting column, the connection gap and weak link between the two are eliminated, making the stress distribution of the entire structure more uniform and reasonable, and being able to withstand greater tension, pressure and torsion, effectively preventing problems such as cracking, loosening or deformation caused by uneven stress during use, greatly improving the reliability and durability of the product.

[0015] In one of the embodiments, the shell assembly includes an inner end face, an outer end face, and a connecting face, the connecting face is arranged on the outer end face, the inner end face is arranged on the connecting face, the fixed base assembly is arranged on the inner end face, the connecting column body is arranged separately from the inner end face, and the inner end face is provided with the accommodating cavity. By arranging the accommodating cavity on the inner end face, the internal structure is orderly hidden, not only the space utilization is optimized, but also the internal components are effectively protected from the direct influence of the external environment, the stability and safety of the overall structure are improved. Secondly, the connecting column body is arranged separately from the inner end face, which skillfully avoids the overlapping of the glue position caused by the direct contact between the connecting column body and the inner end face, forms a place where the local glue position of the product is relatively thick, causes the deformation and shrinkage of the outer end face, ensures the integrity and aesthetics of the shell, and meets the product demand with high appearance requirements. Furthermore, the design of the outer end face and the connecting face provides additional strength support for the shell, enhances the overall pressure resistance, enables the shell to better maintain the shape when facing external impact, extrusion and other situations, prolongs the service life of the product, improves the user experience, and thus stands out in the market competition.

[0016] In one of the embodiments, the shell assembly is semispherical. By setting the shell assembly as semispherical, the shell assembly can uniformly disperse the pressure and impact force it bears. When subjected to external forces such as impact, extrusion and other situations, the force will be conducted in all directions along the semispherical surface, avoiding stress concentration in a certain point or area, thereby effectively reducing the risk of local deformation or damage of the shell, greatly enhancing the stability and impact resistance of the structure, and providing reliable protection for the internal components.

[0017] In one of the embodiments, the connecting column body is provided with a mounting hole for connecting with an external structure. By providing a mounting hole on the connecting column body, a precise and reliable connection method is provided for the connecting column body and the external structure. Through the use of an appropriate connecting piece, tight fixation can be achieved, effectively enhancing the stability of the overall structure and ensuring that the connection between the components of the product is firm during use, reducing the likelihood of loosening or displacement, which is crucial for maintaining the normal operation and performance of the product. Secondly, this standardized mounting hole design greatly improves the assembly efficiency of the product, whether in the production and manufacturing process or in the subsequent maintenance and upgrading process, the connection operation can be quickly and accurately completed, reducing labor costs and time costs. At the same time, the existence of the mounting hole also makes the structural design of the product more versatile and compatible, facilitating integration and expansion with other external components, widening the application range and functional diversity of the product, and bringing more convenience and value to users.

[0018] The second aspect of the present application discloses an electric appliance, which comprises the anti-deformation structure described above, an electric appliance body, and the anti-deformation structure is fixed on the electric appliance body through the mounting hole.

[0019] The second aspect discloses an electric appliance, which installs the deformation prevention structure on the electric appliance body by the mounting hole. On the one hand, compared with the traditional direct screw column connection, the deformation prevention structure significantly reduces the possibility of the problem of the product local glue position being too thick due to the excessive contact area of the connection part and the shell assembly, effectively avoids the deformation and shrinkage of the outer surface of the shell assembly, and makes the outer surface of the shell assembly smooth and clean. At the same time, the precise mounting hole positioning makes the connection more stable and uniformly stressed, avoids the appearance defects caused by excessive local glue, ensures that the electric appliance shell maintains good flatness and aesthetics, and improves the product quality.

[0034] 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.

[0035] The deformation-resistant structure and electrical components of this utility model are described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 9 As shown, this embodiment discloses an anti-deformation structure, including: a shell assembly 1, the shell assembly 1 having a receiving cavity 101; a fixed base assembly 2, the fixed base assembly 2 being disposed on the shell assembly 1 and located in the receiving cavity 101, the thickness of the contact end face of the fixed base assembly 2 and the shell assembly 1 being less than half the thickness of the shell assembly 1, and the fixed base assembly 2 having an opening 201; and a connecting column 3, the connecting column 3 being disposed on the fixed base assembly 2, and the connecting column 3 being used for connection with an external structure.

[0038] The application discloses a deformation prevention structure. First, the shell assembly 1 is provided with a containing cavity 101, which builds a reasonable placement space for the whole internal structure, so that the components are orderly placed and the coordination of the overall structure is ensured. The thickness of the contact end surface of the fixed base assembly 2 and the shell assembly 1 is much smaller than the thickness of the shell assembly 1, which is a design that ingeniously solves the key problem of shrinkage of the shell surface. In the design of the plastic appearance part of the household appliance product in the past, due to the unreasonable internal structure, the glue position of the screw column and other parts is prone to overlap with the main wall of the product, the local glue position is too thick, which violates the principle of uniformity of the main wall of the plastic part, and further causes the surface deformation and shrinkage of the shell assembly 1, which seriously affects the appearance quality of the electric appliance. The thickness of the contact between the fixed base assembly 2 and the shell assembly 1 is controlled, the glue position overlap is effectively avoided, the shell assembly 1 can always maintain a good appearance state, and perfectly fits the household appliance products with high appearance requirements. The opening 201 arranged on the fixed base assembly 2 further optimizes the rationality of the structure, further reduces the contact area between the fixed base assembly 2 and the shell assembly 1, better avoids the surface deformation and shrinkage of the shell assembly 1, and also can reduce the weight of the deformation prevention structure, so that the whole electric appliance is more light. The connection column 3 arranged on the fixed base assembly 2 is used for connecting with the external structure, and in the case of ensuring stable connection, the whole deformation prevention structure is reasonably arranged, and the appearance of the shell assembly 1 and the stability of the internal structure are not negatively affected. In summary, the structure prevents the surface shrinkage of the shell assembly 1 from the root, improves the overall appearance and structural reliability of the product, and has great application and promotion value.

[0039] As shown in Figure 1 and Figure 2 In addition to the features of the above-mentioned embodiments, the present embodiment further limits that the number of fixed base assemblies 2 is multiple, and the multiple fixed base assemblies 2 are arranged on the shell assembly 1 and are circumferentially spaced apart along the inner side of the shell assembly 1. By circumferentially spacing apart the multiple fixed base assemblies 2 along the inner side of the shell assembly 1, more stable and balanced supporting force can be provided for the shell assembly 1, external pressure is effectively dispersed, local deformation of the shell assembly 1 caused by excessive force on a single point is avoided, the overall structural stability of the shell assembly 1 is greatly enhanced, the appearance integrity of the household appliance product is ensured during long-term use, and the product demand with high requirements for appearance parts is met. Secondly, the circumferential spacing makes the connection points of the connection column 3 and the external structure more reasonably distributed, and when assembling or connecting with other components, the connection column 3 can better adapt to the stress situation in different directions, improve the reliability and firmness of the whole product structure, reduce the damage risk caused by improper connection, prolong the service life of the product, improve the market competitiveness of the product, and bring better use experience to the user.

[0040] As shown in Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment is further limited in that: the number of fixed base assemblies 2 is multiple, the number of connecting columns 3 is multiple, and the multiple connecting columns 3 are arranged one-to-one corresponding to the multiple fixed base assemblies 2. By arranging the multiple fixed base assemblies 2 one-to-one corresponding to the multiple connecting columns 3, on the one hand, the multiple connecting points are uniformly distributed, so that the external force acting on the shell assembly 1 can be dispersed to each fixed base assembly 2, avoiding stress concentration, effectively preventing shell deformation, ensuring the flatness and aesthetics of the product appearance, and meeting the demand of household appliances with strict appearance requirements. On the other hand, the one-to-one arrangement enhances the stability and reliability of the internal structure and external connection. Whether it is vibration during transportation or collision, pulling and other situations during daily use, the overall structure can remain stable, reducing the risk of component loosening and displacement, thereby improving the durability and safety of the product, providing users with a more durable and reliable use experience, and improving the competitiveness of the product in the market.

[0041] As shown in Figure 2 and Figure 3 , in addition to the features of the above embodiments, this embodiment is further limited in that: the fixed base assembly 2 includes a support block assembly 21 and a support platform 22, the support block assembly 21 is arranged on the shell assembly 1, the support platform 22 is arranged on the support block assembly 21 and / or the shell assembly 1, the connecting column 3 is arranged on the support platform 22, and the support block assembly 21, the support platform 22 and the shell assembly 1 form an opening 201. By using the combination of the support block assembly 21 and the support platform 22, the fixed base assembly 2 forms a stable support structure that can efficiently bear the external force transmitted by the connecting column 3 and uniformly disperse to the shell assembly 1, effectively enhancing the stability of the overall structure, preventing local deformation of the shell, and ensuring the precision and quality of the product appearance, especially for household appliances with high appearance requirements. Secondly, the opening 201 formed by the support block assembly 21, the support platform 22 and the shell assembly 1 not only reduces the contact area between the fixed base assembly 2 and the shell assembly 1, but also reduces the risk of deformation of the shell assembly 1 caused by stress concentration due to excessive contact area, and reduces the weight of the anti-deformation structure, making the product more lightweight under the premise of ensuring structural strength, easy to install, transport and use, reducing transportation and labor costs, improving production efficiency and market competitiveness of the product, bringing great convenience and advantages to users and manufacturers.

[0042] As shown in Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support block assembly 21 includes a first support block 211 and a second support block 212, the first support block 211 and the second support block 212 are disposed opposite to each other on the outer shell assembly 1, and the support platform 22 is disposed on the first support block 211 and the second support block 212. By disposing the first support block 211 and the second support block 212 opposite to each other on the outer shell assembly 1, a stable support structure is formed, providing a balanced and reliable force point for the support platform 22, effectively dispersing the external force transmitted from the connecting column, avoiding stress concentration at a certain point, thereby greatly enhancing the stability and reliability of the entire anti-deformation structure, ensuring that the outer shell is not easily deformed, and guaranteeing the product's appearance quality.

[0043] like Figure 4 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first support block 211 includes a first outer shell connecting end face 2111 and a first platform connecting end face 2112. The first outer shell connecting end face 2111 is disposed on the outer shell assembly 1, the first platform connecting end face 2112 is disposed on the first outer shell connecting end face 2111, and the support platform 22 is disposed on the first platform connecting end face 2112. The thickness of the portion of the first outer shell connecting end face 2111 that contacts the outer shell assembly 1 is less than half the thickness of the outer shell assembly 1. By designing the thickness of the portion of the first outer shell connecting end face 2111 of the first support block 211 that contacts the outer shell assembly 1 to be much smaller than the thickness of the outer shell assembly 1, the purpose of preventing shrinkage and deformation of the outer surface of the outer shell assembly 1 is achieved. In the traditional design of plastic outer shell parts for household appliances, excessively large connection areas are often a major cause of troublesome problems such as glue overlap and surface shrinkage of the outer shell. This design, by reducing the contact area, effectively avoids excessive glue accumulation at the connection points, preventing localized stress changes caused by uneven glue application. This significantly reduces the risk of surface shrinkage in the housing assembly 1, ensuring the flatness and aesthetics of the housing, perfectly meeting the stringent requirements for appearance quality. Simultaneously, it reduces the scrap rate due to appearance defects, improving production efficiency and product yield. In the long run, it not only reduces production costs but also helps enhance the product's market competitiveness and brand image, providing users with aesthetically pleasing and reliable home appliances. Moreover, compared to the traditional crater structure, the structure of this application ensures the structural strength of the housing assembly 1.

[0044] like Figure 4 , Figure 5 and Figure 7As shown, in addition to the features of the above embodiments, the present embodiment is further limited in that: the second support block 212 comprises a second shell connecting end face 2121 and a second platform connecting end face 2122, the second shell connecting end face 2121 is arranged on the shell assembly 1, the second platform connecting end face 2122 is arranged on the second shell connecting end face 2121, the support platform 22 is arranged on the second platform connecting end face 2122, and the thickness of the part of the second shell connecting end face 2121 in contact with the shell assembly 1 is less than half the thickness of the shell assembly 1. By designing the thickness of the part of the second shell connecting end face 2121 of the second support block 212 in contact with the shell assembly 1 to be much smaller than the thickness of the shell assembly 1, the possibility of problems such as glue position overlap and surface shrinkage of the shell caused by excessive connection area is fundamentally reduced. In the production process of plastic appearance parts, excessive connection area is easy to cause uneven distribution of glue, causing local glue position to be too thick, and then causing the shell surface to shrink, seriously affecting the appearance quality and performance of the product. This design effectively avoids this risk, so that the shell can remain smooth and flat, meeting the strict requirements of high-end home appliance products for appearance delicacy. Not only reduces the scrap rate and rework cost, but also improves the overall quality and market competitiveness of the product, providing users with a more beautiful, durable and stable performance product, while ensuring structural stability, perfectly solving the appearance defect problem in traditional design.

[0045] As shown in Figure 3 , Figure 6 and Figure 9 , in addition to the features of the above embodiments, the present embodiment is further limited in that: the support platform 22 comprises a shell connecting end face 221, the shell connecting end face 221 is arranged on the shell assembly 1, and the thickness of the part of the shell connecting end face 221 in contact with the shell assembly 1 is less than half the thickness of the shell assembly 1. By designing the thickness of the part of the shell connecting end face 221 in contact with the shell assembly 1 to be much smaller than the thickness of the shell assembly 1, the possibility of problems such as glue position overlap and surface shrinkage of the shell assembly 1 is greatly reduced. In the molding process of plastic parts, smaller contact area can effectively avoid uneven stress caused by excessive local glue, prevent the shell from deforming or sinking due to inconsistent shrinkage, and ensure the flatness and beauty of the product appearance, meeting the demanding product requirements for appearance. Compared with the traditional crater structure, this structure weakens the local structural strength, because it changes the original material distribution during glue reduction, making this part more prone to deformation or damage when subjected to external force. On the contrary, the anti-deformation structure of the present embodiment adopts a combined design of multiple support block assemblies 21 and support platforms 22, forming a stable support system that can more evenly distribute external forces, enhancing the stability and reliability of the overall structure, ensuring that the product can withstand various external forces during long-term use, reducing the risk of failure or damage due to insufficient structural strength, and prolonging the service life of the product.

[0046] As Figure 2 and Figure 3 shown, in addition to the features of the above embodiments, this embodiment is further limited in that the support block assembly 21 and the support platform 22 are integrally formed. By integrally forming the support block assembly 21 and the support platform 22, the connection gaps between the components are eliminated, greatly enhancing the overall structural strength and stability, enabling it to better withstand external forces, reducing the risk of deformation caused by loose connections or gaps, ensuring the accuracy and integrity of the product shell, meeting the product demand for higher appearance quality. At the same time, it reduces the quality problems caused by assembly errors, improves the yield of the product, and thus improves the market competitiveness of the product, creating more benefits for the enterprise.

[0047] As Figure 1 and Figure 2 shown, in addition to the features of the above embodiments, this embodiment is further limited in that the fixed base assembly 2 and the connecting column 3 are integrally formed. By integrally forming the fixed base assembly 2 and the connecting column 3, the connection gaps and weak links between the two are eliminated, making the stress distribution of the entire structure more uniform and reasonable, capable of withstanding greater tension, pressure and torque, effectively preventing problems such as cracking, loosening or deformation caused by uneven stress during use, greatly improving the reliability and durability of the product.

[0048] As Figure 1 and Figure 3 shown, in addition to the features of the above embodiments, this embodiment is further limited in that the shell assembly 1 includes an inner end face 11, an outer end face 12 and a connecting face 13, the connecting face 13 is provided on the outer end face 12, the inner end face 11 is provided on the connecting face 13, the fixed base assembly 2 is provided on the inner end face 11, the connecting column 3 is provided separately from the inner end face 11, and the inner end face 11 is provided with a receiving cavity 101. By providing the receiving cavity 101 on the inner end face 11, the internal structure is hidden in order, not only optimizing the space utilization, but also effectively protecting the internal components from the direct influence of the external environment, improving the stability and safety of the overall structure. Secondly, the connecting column 3 is provided separately from the inner end face 11, which cleverly avoids the overlapping of the glue position caused by the direct contact between the connecting column 3 and the inner end face 11, forming a place where the local glue position of the product is thicker, making the outer end face 12 deform and shrink, ensuring the integrity and aesthetics of the shell, meeting the product demand for higher appearance requirements. Thirdly, the design of the outer end face 12 and the connecting face 13 provides additional strength support for the shell, enhancing the overall compression resistance, enabling it to better maintain its shape when facing external impact, extrusion and other situations, prolonging the service life of the product and improving the user's experience, thus standing out in the market competition.

[0049] As Figure 1As shown, in addition to the features of the above embodiments, this embodiment is further limited in that the shell assembly 1 is semi-spherical. By making the shell assembly 1 semi-spherical, it can uniformly disperse the pressure and impact force it bears. When subjected to external forces, such as impact, extrusion, etc., the force will be conducted in all directions along the semi-spherical surface, avoiding stress concentration in a certain point or area, thereby effectively reducing the risk of local deformation or damage of the shell, greatly enhancing the stability and impact resistance of the structure, and providing reliable protection for the internal components.

[0050] As shown in Figure 1 and Figure 2 shown, in addition to the features of the above embodiments, this embodiment is further limited in that the connecting column 3 is provided with a mounting hole 301 for connecting with the external structure. By providing the mounting hole 301 in the connecting column 3, a precise and reliable connection method is provided for the connecting column 3 and the external structure, and through the use of appropriate connecting parts, a tight fixation can be achieved, effectively enhancing the stability of the overall structure and ensuring that the connection between the components is firm during use, reducing the likelihood of loosening or displacement, which is crucial for maintaining the normal operation and performance of the product. Secondly, this standardized mounting hole design greatly improves the assembly efficiency of the product, whether in the production and manufacturing process or in the subsequent maintenance and upgrading process, the connection operation can be quickly and accurately completed, reducing labor and time costs. At the same time, the presence of the mounting hole 301 also makes the structural design of the product more versatile and compatible, facilitating integration and expansion with other external components, broadening the application range and functional diversity of the product, and bringing more convenience and value to users.

[0051] Embodiment 2

[0052] As shown in Figures 1 to 9 this embodiment discloses an electrical appliance, comprising: the above-mentioned deformation-resistant structure; an electrical appliance body, the deformation-resistant structure being fixed to the electrical appliance body through the mounting hole 301.

[0053] The second aspect of the present application discloses an electrical appliance, which uses the mounting hole 301 to install the deformation-resistant structure on the electrical appliance body. On the one hand, compared with the traditional direct screw column connection, the deformation-resistant structure significantly reduces the possibility of problems such as overlapping of the glue position, formation of a thicker local glue position, and deformation and shrinkage of the outer surface of the shell assembly 1 due to the excessive contact area between the connection part and the shell assembly 1, effectively avoiding the deformation and shrinkage of the outer surface of the shell assembly 1, and keeping the outer surface of the shell assembly 1 smooth and clean. At the same time, the precise positioning of the mounting hole 301 makes the connection more stable and uniformly stressed, avoiding appearance defects caused by excessive local glue, ensuring that the electrical appliance shell maintains good flatness and aesthetics, and improving product quality.

[0054] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.

[0055] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the present application patent. It should be pointed out that, for ordinary skilled in the art, under the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent shall be subject to the appended claims.
