Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a grounding structure and an electrical appliance. Background Technology

[0002] Currently, many electronic devices on the market typically have metal casings for their displays. To prevent static electricity buildup on the casing or safety hazards and performance interference caused by contact with charged objects, a thick layer of insulating varnish is often applied to the surface of the metal casing. However, this treatment leads to cumbersome manufacturing processes and significantly increased costs. Furthermore, traditional grounding solutions often use pins or spring contacts to achieve grounding functionality; however, this method has strict requirements on product height, severely restricting the design of thinner and lighter products. In the circuit board manufacturing process, the installation of pins or spring contacts requires multiple complex steps, which not only increases production costs but also easily leads to a high defect rate, making it difficult to meet the demands of modern electronic products for efficient production and compact structures. Utility Model Content

[0003] Therefore, it is necessary to provide a grounding structure and electrical appliance to address the problem of poor grounding structure in electrical appliances.

[0004] A grounding structure includes: a housing assembly having a receiving cavity and a mounting hole; a display screen assembly disposed on the housing assembly and located in the receiving cavity; a conductive element having one side disposed on the display screen assembly and located in the mounting hole; and a circuit board assembly disposed on the housing assembly and located in the receiving cavity, the circuit board assembly abutting against the other side of the conductive element.

[0005] The above-disclosed grounding structure is used in electrical appliances. Compared with traditional solutions, this grounding structure establishes a grounding connection between the display screen assembly and the circuit board assembly through conductive components, effectively avoiding many drawbacks. Firstly, it eliminates the complex process of coating the metal casing of the display screen with insulating varnish, achieving grounding directly through conductive components, reducing material and process inputs, and significantly lowering production costs. Secondly, it changes the grounding method using pins or spring contacts; the conductive components are soft and easily compressible, breaking through the limitations on product height and greatly reducing the overall thickness of the electrical appliance, making it possible to design thinner and lighter products, meeting the demand for compact and portable modern electronic products. Moreover, the application of conductive components simplifies the circuit board manufacturing process, reducing the complex processes caused by the installation of pins and spring contacts, not only reducing production difficulty but also reducing the defect rate during production, improving production efficiency and product quality stability. At the same time, this simple and efficient grounding method makes the assembly of electrical appliances more convenient, shortens the production cycle, and further enhances the company's production efficiency and market competitiveness.

[0006] In one embodiment, there are multiple conductive elements and multiple mounting holes. Each conductive element mates with one of the mounting holes, and the multiple conductive elements are sandwiched between the display assembly and the circuit board assembly. By mates of multiple conductive elements with mounting holes and sandwiching them between the display assembly and the circuit board assembly, the contact pressure between the components is distributed, avoiding poor contact or structural damage caused by excessive force at a single point. This makes the connection between the display assembly, conductive elements, and circuit board assembly more robust and reliable, maintaining a stable grounding state even when the product is subjected to external forces such as vibration or compression. Simultaneously, multiple conductive elements increase the conductive path for grounding, reduce the overall grounding resistance, and improve the efficiency of electrostatic discharge and current conduction. This allows for faster and more effective conduction of static electricity or abnormal current generated by the display assembly to the grounding pads of the circuit board assembly, enhancing the product's anti-interference capability and electrical safety. Furthermore, this multi-conductive element layout allows the grounding function to be maintained by other conductive elements when some conductive elements fail, improving the redundancy and reliability of the grounding system. Moreover, the cooperation between multiple mounting holes and conductive elements facilitates precise positioning and installation, improving assembly efficiency and accuracy.

[0007] In one embodiment, the display assembly includes a display section and a grounding section. The grounding section is disposed on the display section, and both the display section and the grounding section are disposed on the housing assembly. The grounding section is located within the receiving cavity, and one side of the conductive element is disposed on the grounding section. By concentrating the grounding function on the grounding section, mechanical stress and electrical interference that may occur to the display section due to grounding operations are avoided. This ensures the stability of the displayed image and allows for the targeted selection of highly conductive materials for efficient conduction of static electricity and abnormal currents. Furthermore, as an independent structure, the grounding section provides a clear mounting point for the conductive element, simplifying the assembly process and improving production efficiency.

[0008] In one embodiment, the conductive element includes a first contact surface and a second contact surface, which are disposed opposite to each other. The first contact surface is disposed on the display assembly, and the second contact surface abuts against the circuit board assembly. By setting the conductive element with opposing first and second contact surfaces and connecting them to the display assembly and circuit board assembly respectively, the performance and practicality of the grounding structure are greatly improved. On the one hand, the first contact surface fits tightly against the display assembly, and the second contact surface abuts against the circuit board assembly, forming a stable conductive path, enabling efficient conduction of static electricity and abnormal current, significantly enhancing the product's anti-interference capability and electrical safety. On the other hand, since the conductive element is usually made of flexible material, the compression characteristics between the first and second contact surfaces can adaptively compensate for the assembly tolerances between the display assembly and the circuit board assembly, avoiding stress concentration caused by rigid contact, and ensuring a stable connection even under complex environments such as vibration and compression. In addition, the dual-contact surface design provides a clear installation benchmark for the conductive element, facilitating precise positioning through mounting holes during assembly, simplifying the installation process, improving assembly efficiency, reducing production defects and subsequent maintenance costs caused by poor contact, and providing strong support for the large-scale production and stable operation of the product.

[0009] In one embodiment, the housing assembly includes a front shell and a rear cover. The rear cover is disposed on the front shell and encloses the receiving cavity. The display assembly and the circuit board assembly are both disposed on the front shell, and the rear cover abuts against the circuit board assembly. The receiving cavity formed by the front shell and rear cover provides a stable and enclosed physical space for the display assembly and circuit board assembly, effectively resisting external dust, moisture, and mechanical impact, protecting internal precision components, and extending product lifespan. During assembly, the front shell serves as the mounting reference for the display assembly and circuit board assembly, simplifying the positioning and fixing process. The rear cover abuts against the circuit board assembly, further securing the circuit board assembly and preventing it from shaking within the receiving cavity. The close contact also aids in heat dissipation for the circuit board assembly, improving the product's electrical performance. Furthermore, the separate design of the front shell and rear cover facilitates the disassembly and maintenance of internal components, reducing repair difficulty.

[0010] In one embodiment, the front cover includes a front cover body, a partition plate, and connecting posts. The partition plate is disposed on the front cover body, and there are multiple connecting posts disposed on the partition plate. The rear cover is disposed on the multiple connecting posts, and the display assembly is disposed on the front cover body. The partition plate is located between the display assembly and the circuit board assembly, and the partition plate has mounting holes. By placing the display assembly on the front cover body, a stable mounting surface is provided for the display assembly, ensuring its precise positioning. The partition plate, located between the display assembly and the circuit board assembly, not only enables precise positioning and installation of conductive components through the mounting holes but also physically separates the two components, reducing electromagnetic interference and improving electrical safety. Multiple connecting posts are evenly distributed on the partition plate, providing a reliable mounting reference for the rear cover. The rear cover is fixed to the partition plate with screws, forming a stable closed cavity that effectively resists external impacts and dust intrusion, protecting the internal components.

[0011] In one embodiment, the rear cover includes a rear cover body and top blocks. The rear cover body is disposed on the front shell, and there are multiple top blocks disposed on the rear cover body, abutting against the circuit board assembly. This combination of the rear cover body and multiple top blocks, working in conjunction with the front shell and circuit board assembly, significantly improves structural stability, enhances functionality, and facilitates production and maintenance. The rear cover body is connected to the front shell, forming a closed cavity that provides basic protection for internal components, resisting external physical impacts and dust intrusion. The multiple top blocks, evenly distributed on the rear cover body, directly abut against the circuit board assembly, forming a multi-point support structure. This not only prevents the circuit board from shifting or moving within the cavity, ensuring stable contact between it and the display assembly and conductive components, and guaranteeing the normal operation of the grounding system, but also aids in heat dissipation through close contact with the circuit board, improving the product's electrical performance. In addition, the top block design makes the assembly process of the back cover and the circuit board simpler, allowing for precise positioning and installation, reducing contact problems caused by assembly deviations. During later maintenance of the product, the circuit board can be quickly positioned by removing the back cover and using the top block, facilitating inspection and replacement of components, and reducing maintenance difficulty and cost.

[0012] In one embodiment, the front cover body, the partition plate, and the connecting post are integrally formed. By integrally forming the front cover body, partition plate, and connecting post, the one-piece molding process eliminates the seams and weak points between components in traditional splicing methods, making the front shell a solid whole. This can more effectively resist external impacts and prevent deformation caused by collisions and compression, providing reliable physical protection for the internal display screen components and circuit board components. In the manufacturing process, one-piece molding reduces the complex processes of assembling multiple components, eliminating the need for additional connectors or assembly processes, reducing labor costs and production time. It also avoids dimensional deviations caused by assembly errors, improving product consistency and yield. From the perspective of assembly convenience, the one-piece molded front shell provides a precise installation benchmark for the display screen components, circuit board components, and conductive components. Each component can be directly positioned and installed according to the preset structure, simplifying the assembly process and improving overall assembly efficiency. In addition, this design also enhances the product's sealing performance, reducing the risk of external dust and moisture entering the cavity, helping to maintain the performance stability of internal components and extend the product's service life.

[0013] In one embodiment, the circuit board assembly has multiple notches, and the housing assembly has multiple connecting posts, with each notch and connecting post corresponding to the other. This one-to-one correspondence between the multiple notches on the circuit board assembly and the multiple connecting posts on the housing assembly plays a crucial role in structural stability, assembly efficiency, and maintenance convenience. This matching method provides a precise positioning reference for the circuit board assembly. During assembly, simply aligning the notch with the connecting post allows for quick installation, effectively avoiding installation misalignment caused by manual operation or equipment errors. It also has a fault-prevention function; if the assembly direction is incorrect and the notch and connecting post do not match, it can be detected and corrected promptly, reducing rework costs. From a structural stability perspective, multiple connecting posts passing through corresponding notches and fixed to the back cover form a multi-point support structure, evenly distributing external forces and preventing the circuit board from bending or breaking due to uneven stress. This effectively protects the solder joints and components on the circuit board and prevents the risk of poor contact or open circuits caused by circuit board displacement when the product is subjected to vibration, impact, or pressure.

[0014] The second aspect of this application discloses an electrical appliance, which includes the above-described grounding structure and an appliance body, wherein the grounding structure is disposed on the appliance body.

[0015] The second aspect disclosed above discloses an electrical appliance in which the aforementioned grounding structure is installed on the appliance body. This grounding structure establishes a stable connection between the display screen assembly and the circuit board assembly through conductive components, which can quickly conduct static electricity or abnormal current generated during the operation of the appliance to the ground, avoiding component damage or electric shock risks caused by static electricity accumulation. It is especially suitable for electrical equipment with frequent display screen operation, effectively ensuring user safety and equipment reliability. In terms of stability, the front shell and rear cover of the housing assembly form a closed cavity. Combined with the high-strength structure of the front cover body, partition plate, and connecting post integrally formed, it provides solid protection for the internal components and can resist external physical impacts, dust, and moisture intrusion. At the same time, the matching design of the circuit board assembly notch and the connecting post ensures that the circuit board is firmly installed, prevents component displacement caused by vibration, maintains the stable operation of the grounding system, and ensures that the appliance continues to work normally in complex environments.

[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 grounding structure and electrical components of some embodiments of this utility model are described below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figures 1 to 9 As shown, this embodiment discloses a grounding structure, including: a housing assembly 1, which has a receiving cavity 101 and a mounting hole 102; a display screen assembly 2, which is disposed on the housing assembly 1 and located in the receiving cavity 101; a conductive element 3, one side of which is disposed on the display screen assembly 2 and located in the mounting hole 102; and a circuit board assembly 4, which is disposed on the housing assembly 1 and located in the receiving cavity 101, with the other side of the circuit board assembly 4 abutting against the other side of the conductive element 3.

[0035] This application discloses a grounding structure for electrical appliances. Compared to traditional solutions, this grounding structure establishes a grounding connection between the display screen assembly 2 and the circuit board assembly 4 through a conductive component 3, effectively avoiding many drawbacks. First, it eliminates the complex process of coating the metal casing of the display screen with insulating varnish, achieving grounding directly through the conductive component 3, reducing material and process inputs, and significantly lowering production costs. Second, it changes the grounding method using pins or spring contacts; the conductive component 3 is flexible and easily compressible, overcoming the limitations on product height and greatly reducing the overall thickness of the electrical appliance, making it possible to design thinner and lighter products and meeting the demand for compact and portable modern electronic products. Moreover, the application of the conductive component 3 simplifies the circuit board manufacturing process, reducing the complex processes caused by the installation of pins and spring contacts, not only reducing production difficulty but also reducing the defect rate during production, improving production efficiency and product quality stability. At the same time, this simple and efficient grounding method makes the assembly of electrical appliances more convenient, shortens the production cycle, and further enhances the company's production efficiency and market competitiveness.

[0036] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of conductive elements 3 is multiple, the number of mounting holes 102 is multiple, the multiple conductive elements 3 are matched one-to-one with the multiple mounting holes 102, and the multiple conductive elements 3 are sandwiched between the display assembly 2 and the circuit board assembly 4. By matching the multiple conductive elements 3 with the mounting holes 102 one-to-one and sandwiching them between the display assembly 2 and the circuit board assembly 4, the contact pressure between the components is distributed, avoiding poor contact or structural damage caused by excessive force at a single point, making the connection between the display assembly 2, the conductive elements 3 and the circuit board assembly 4 more robust and reliable, and maintaining a stable grounding state even when the product is subjected to external forces such as vibration and compression. At the same time, the multiple conductive elements 3 increase the conductive path for grounding, reduce the overall grounding resistance, and improve the efficiency of electrostatic discharge and current conduction, enabling more rapid and effective conduction of static electricity or abnormal current generated by the display assembly to the grounding pads of the circuit board assembly, enhancing the product's anti-interference capability and electrical safety. In addition, this layout of multiple conductive elements 3 can also maintain the grounding function by relying on other conductive elements 3 when some conductive elements fail, improving the redundancy and reliability of the grounding system. Furthermore, the cooperation between the multiple mounting holes 102 and the conductive component 3 facilitates precise positioning and installation, improving assembly efficiency and accuracy.

[0037] like Figure 2 , Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the display assembly 2 includes a display section 21 and a grounding section 22, the grounding section 22 is disposed on the display section 21, both the display section 21 and the grounding section 22 are disposed on the housing assembly 1, the grounding section 22 is located in the receiving cavity 101, and one side of the conductive element 3 is disposed on the grounding section 22. By concentrating the grounding function on the grounding section 22, the mechanical stress and electrical interference that may be generated by the grounding operation of the display section 21 are avoided, which not only ensures the stability of the display screen, but also allows for the targeted selection of highly conductive materials for the grounding section 22 to efficiently conduct static electricity and abnormal current; at the same time, the grounding section 22, as an independent structure, provides a clear installation positioning point for the conductive element 3, simplifying the assembly process and improving production efficiency.

[0038] like Figure 2 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the conductive element 3 includes a first contact surface 31 and a second contact surface 32, the first contact surface 31 and the second contact surface 32 are disposed opposite to each other, the first contact surface 31 is disposed on the display screen assembly 2, and the second contact surface 32 abuts against the circuit board assembly 4. By arranging the conductive element 3 with the opposite first contact surface 31 and second contact surface 32, and connecting it to the display screen assembly 2 and the circuit board assembly 4 respectively, the performance and practicality of the grounding structure are greatly improved. On the one hand, the first contact surface 31 fits tightly against the display screen assembly 2, and the second contact surface 32 abuts against the circuit board assembly 4, forming a stable conductive path that enables efficient conduction of static electricity and abnormal current, significantly enhancing the product's anti-interference capability and electrical safety. On the other hand, since the conductive component 3 is usually made of flexible material, the compression characteristics between the first and second contact surfaces can adaptively compensate for the assembly tolerances between the display screen assembly 2 and the circuit board assembly 4, avoiding stress concentration caused by rigid contact and ensuring that the connection remains stable under complex environments such as vibration and compression. In addition, the dual contact surface design provides a clear installation benchmark for the conductive component 3, facilitating precise positioning through the mounting hole 102 during assembly, simplifying the installation process, improving assembly efficiency, reducing the production defect rate and subsequent maintenance costs caused by poor contact, and providing strong support for the large-scale production and stable operation of the product.

[0039] like Figure 1 , Figure 2 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a front shell 11 and a rear cover 12. The rear cover 12 is disposed on the front shell 11 and encloses to form a receiving cavity 101. The display assembly 2 and the circuit board assembly 4 are both disposed on the front shell 11, and the rear cover 12 abuts against the circuit board assembly 4. By enclosing the receiving cavity 101 formed by the front shell 11 and the rear cover 12, a stable and enclosed physical space is provided for the display assembly 2 and the circuit board assembly 4, effectively resisting external dust, moisture and mechanical impact, protecting internal precision components, and extending the product's service life. During assembly, the front shell 11 serves as the installation reference for the display assembly 2 and the circuit board assembly 4, simplifying the positioning and fixing process. The rear cover 12 abuts against the circuit board assembly 4, which not only further fixes the circuit board assembly 4 and prevents it from shaking in the receiving cavity 101, but also helps to dissipate heat from the circuit board assembly 4 through close contact, improving the product's electrical performance. In addition, the separate design of the front shell 11 and the rear cover 12 facilitates the disassembly and maintenance of internal components, reducing the difficulty of maintenance.

[0040] like Figure 2 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the front cover 11 includes a front cover body 111, a partition plate 112, and connecting posts 113. The partition plate 112 is disposed on the front cover body 111, and there are multiple connecting posts 113 disposed on the partition plate 112. The rear cover 12 is disposed on the multiple connecting posts 113. The display assembly 2 is disposed on the front cover body 111. The partition plate 112 is located between the display assembly 2 and the circuit board assembly 4, and the partition plate 112 is provided with mounting holes 102. By disposing of the display assembly 2 on the front cover body 111, a stable mounting surface is provided for the display assembly 2, ensuring its accurate positioning. The partition plate 112 is located between the display screen assembly 2 and the circuit board assembly 4. It not only enables the precise positioning and installation of the conductive component 3 through the mounting hole 102, but also physically separates the two components, reducing electromagnetic interference between them and improving electrical safety. Multiple connecting posts 113 are evenly distributed on the partition plate 112, providing a reliable mounting reference for the back cover 12. They are fixed to the back cover 12 by screws, forming a stable closed cavity that effectively resists external impacts and dust intrusion, protecting the internal components.

[0041] like Figure 2 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: the rear cover 12 includes a rear cover body 121 and top blocks 122. The rear cover body 121 is disposed on the front shell 11, and there are multiple top blocks 122 disposed on the rear cover body 121. The multiple top blocks 122 abut against the circuit board assembly 4. By adopting the combined design of the rear cover body 121 and multiple top blocks 122, and cooperating with the front shell 11 and the circuit board assembly 4, it has significant effects in terms of structural fixation, functional enhancement, and production maintenance. The rear cover body 121 is connected to the front shell 11, forming a closed receiving cavity 101, providing basic protection for the internal components and resisting external physical impacts and dust intrusion; while the multiple top blocks 122 are evenly distributed on the rear cover body 121, directly abutting against the circuit board assembly 4, forming a multi-point support structure, which not only prevents the circuit board from shaking and shifting in the cavity, ensuring stable contact between it and the display screen assembly 2 and the conductive parts 3, and ensuring the normal operation of the grounding system, but also helps to dissipate heat from the circuit board by closely abutting against it, thus improving the electrical performance of the product. In addition, the design of the top block 122 makes the assembly process of the back cover and the circuit board simpler, and allows for precise positioning and installation, reducing contact problems caused by assembly deviations. During later maintenance of the product, the circuit board can be quickly positioned by removing the back cover and using the top block, which facilitates inspection and replacement of parts and reduces maintenance difficulty and cost.

[0042] like Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines that the front cover body 111, the partition plate 112 and the connecting post 113 are integrally formed. By integrally molding the front cover body 111, partition plate 112, and connecting post 113, the one-piece molding process eliminates the seams and weak points between components in traditional splicing methods, making the front shell 11 a solid whole. This can more effectively resist external impacts and prevent deformation caused by collisions and squeezing, providing reliable physical protection for the internal display screen assembly 2 and circuit board assembly 4. In the manufacturing process, one-piece molding reduces the complex process of assembling multiple components, eliminating the need for additional connectors or assembly processes, reducing labor costs and production time. At the same time, it avoids dimensional deviations caused by assembly errors, improving product consistency and yield. From the perspective of assembly convenience, the one-piece molded front shell 11 provides a precise installation benchmark for the display screen assembly 2, circuit board assembly 4, and conductive components 3. Each component can be directly positioned and installed according to the preset structure, simplifying the assembly process and improving overall assembly efficiency. In addition, this design also enhances the product's sealing performance, reducing the risk of external dust and moisture entering the receiving cavity 101, helping to maintain the performance stability of internal components and extend the product's service life.

[0043] like Figure 2 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the circuit board assembly 4 is provided with notches 401, and the number of notches 401 is multiple; the housing assembly 1 is provided with connecting posts 113, and the number of connecting posts 113 is multiple; the multiple notches 401 and the multiple connecting posts 113 are matched one-to-one. By matching the multiple notches 401 on the circuit board assembly 4 with the multiple connecting posts 113 on the housing assembly 1 one-to-one, it plays a key role in terms of structural stability, assembly efficiency, and maintenance convenience. This matching method provides a precise positioning reference for the circuit board assembly 4. During the assembly process, installation can be quickly completed by simply aligning the notches 401 with the connecting posts 113, effectively avoiding installation offset caused by manual operation or equipment errors. It also has an error-proof function; if the assembly direction is incorrect and the notches and connecting posts cannot match, it can be detected and corrected in time, reducing rework costs. From the perspective of structural stability, multiple connecting pillars 113 pass through the corresponding notches 401 and are fixed to the back cover 12, forming a multi-point support structure. This evenly distributes external forces, preventing the circuit board from bending or breaking due to uneven stress. It effectively protects the solder joints and components on the circuit board. When the product is subjected to vibration, impact, or pressure, it can prevent the circuit board from shifting, which could lead to poor contact or open circuit of the conductive parts 3.

It is especially suitable for electrical equipment that frequently operates the display screen, effectively ensuring user safety and equipment reliability. In terms of stability, the front shell 11 and the rear cover 12 of the housing assembly 1 form a closed receiving cavity 101. Combined with the high-strength structure of the front cover body 111, the partition plate 112 and the connecting post 113 integrally formed, it provides solid protection for the internal components and can resist external physical impact, dust and moisture intrusion. At the same time, the matching design of the notch 401 of the circuit board assembly 4 and the connecting post 113 ensures that the circuit board is firmly installed, prevents component displacement caused by vibration, maintains the stable operation of the grounding system, and ensures that the appliance continues to work normally in complex environments.
