Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliances, and in particular to a digital tube fixing structure and an electrical appliance. Background Technology
[0002] In existing technologies, there are two main ways to fix digital tubes. One is to fix the digital tube to the PCB with screws. The disadvantage of this method is that the digital tube needs to have two screw ears, and the screw heads cannot be countersunk; they must protrude from the circuit board. This requires reserving space for the screw heads, thus increasing the product's height, which is not suitable for products that need to be made thin. The other method is to fix the digital tube to the PCB with glue. However, the glue will crack over time, causing the digital tube to loosen. Utility Model Content
[0003] Therefore, it is necessary to provide a digital tube fixing structure and electrical appliance to address the problem of unreasonable fixing methods for digital tubes.
[0004] A digital tube fixing structure includes: a digital tube body; a fixing component disposed on the digital tube body; and a PCB board assembly having a first fixing hole, with one end of the fixing component away from the digital tube body passing through the first fixing hole, the portion of the fixing component passing through the first fixing hole being connected to the PCB board assembly, and the PCB board assembly abutting against the digital tube body.
[0005] The above-disclosed digital tube fixing structure completely eliminates the drawbacks of traditional digital tube fixing methods from the perspective of space utilization. It eliminates the need for additional screw holes / ears on the digital tube body, avoiding the problem of increased size due to reserved ear positions. It also avoids the risk of loosening caused by adhesive aging and cracking when using glue. The fixing components precisely match the PCB board components, allowing the digital tube body to fit tightly against the PCB board during installation. Furthermore, it eliminates the need for extra space for protruding screw heads, significantly reducing the product's thickness. This perfectly aligns with the current trend of thinner and lighter electronic products, easily meeting the compact design requirements of both handheld small appliances and space-constrained embedded devices. Secondly, it revolutionarily simplifies material management and assembly processes. Traditional screw fixing methods require a large number of screws and tools such as screwdrivers, increasing material costs and management complexity. Glue fixing faces issues such as glue shelf life and inconsistent application processes. This structure reduces the complex procurement and inventory management of screws and other materials, lowering costs caused by material stockpiling and loss. The assembly process is particularly convenient and efficient. Operators simply need to smoothly pass the fixing component through the first fixing hole of the PCB board assembly, and then melt the exposed part of the fixing component with a soldering iron tip to quickly complete the installation. This eliminates the need for time-consuming screw tightening or long waiting times for glue to cure, significantly shortening the production cycle, reducing labor costs, and improving production efficiency. Furthermore, the fixing component and the PCB board assembly interlock to form a stable connection, fundamentally eliminating the risk of loosening or displacement of the digital tube, ensuring long-term stable operation of the electrical appliance, and reducing repair costs caused by loose components. Moreover, the positioning characteristics of the fixing component ensure that the digital tube is accurately positioned every time it is installed, reducing display abnormalities caused by installation deviations, laying a solid foundation for high-quality product operation, and comprehensively improving the product's reliability and stability.
[0006] In one embodiment, the fixing component includes a fixing column and a fixing member. The fixing column is disposed on the digital tube body, and the fixing member is disposed on the end of the fixing column away from the digital tube body. The fixing column passes through the first fixing hole, and the fixing member is connected to the PCB board assembly. By directly connecting the fixing column to the digital tube body, the operator only needs to align the fixing column with the first fixing hole of the PCB board assembly and insert it, then use a soldering iron tip to melt the exposed part of the fixing component to form the fixing member. Compared with the traditional complex fixing method, the operation steps are greatly simplified, and even novice workers can quickly get started, greatly improving the assembly speed and reducing the manpower input and time cost of the production line. The fixing member is located at the end of the fixing column away from the digital tube body and abuts against the PCB board assembly, forming a stable three-point support structure. This design makes the connection between the digital tube body and the PCB board assembly more secure, effectively resisting vibrations and collisions during daily use of the appliance, as well as bumps during transportation, greatly reducing the risk of loosening and displacement of the digital tube body, ensuring stable internal circuit connections of the appliance, reducing malfunctions caused by poor contact, and extending the service life of the appliance. Meanwhile, given the slim design of the fixed column, which occupies very little space compared to the large screw holes required by traditional screw fixing, the surrounding layout of the digital tube body is more compact, leaving more space for other internal components of the appliance. This facilitates the miniaturization and multi-functional upgrade of the product, meets the growing consumer demand for high-performance, small-sized appliances, and further enhances the product's market competitiveness.
[0007] In one embodiment, the fixing component includes a first fixing surface and a second fixing surface. The first fixing surface is disposed on the fixing column and abuts against the PCB board assembly. The second fixing surface is disposed opposite to the first fixing surface. By tightly fitting the first fixing surface against the PCB board assembly, a solid support point is provided for the digital tube body, ensuring the vertical stability of the digital tube body and effectively preventing sinking or displacement caused by gravity or slight shaking. When the electrical appliance encounters accidental collisions, drops, or vibrations caused by frequent plugging and unplugging of external devices, this fixing structure can firmly lock the digital tube body, keeping it stable in the correct position, ensuring the continuity and stability of internal electrical connections, and reducing the probability of failure. The first fixing surface is directly connected to the fixing column, ensuring the initial accuracy of installation. The operator only needs to insert the fixing column into the hole and then use a soldering iron tip to melt the exposed part of the fixing component to form the first fixing surface and the second fixing surface. This reduces the thickness of the product, simplifies the operation process, improves installation efficiency, and ensures the final installation quality, providing strong support for large-scale and efficient production.
[0008] In one embodiment, the fastener is a plastic component, which is thermally bonded to the PCB board assembly. By thermally bonding the fastener to the PCB board assembly, a seamless connection is achieved, effectively preventing loosening due to prolonged use compared to mechanical connections. After thermal bonding, the plastic component adheres well to the surface of the PCB board assembly, maintaining the stability of the digital display tube under external impacts such as electrical collisions or vibrations, reducing the risk of displacement or detachment, and thus ensuring the normal display function of the electrical appliance.
[0009] In one embodiment, the fastener is manufactured by hot-melt. By making the fastener by hot-melt, the fastener can be melted and deformed using a soldering iron tip, and finally completely adhered to the PCB board assembly. On the one hand, this ensures that the digital tube body can be firmly fixed to the PCB board assembly. On the other hand, compared with the traditional fixing method, this fixing method can effectively avoid the problem of the digital tube body increasing in size due to the reserved ear position. It can also avoid the risk of the digital tube loosening due to the aging and cracking of the adhesive when using glue fixing. Furthermore, it can avoid the need to reserve extra space for protruding screw heads, reducing the space occupied by the overall structure of the digital tube, which is conducive to the miniaturization of electrical equipment.
[0010] In one embodiment, the cross-sectional area of the fixing member is larger than the cross-sectional area of the first fixing hole. By setting the cross-sectional area of the fixing member to be larger than that of the first fixing hole, the digital tube body is firmly fixed to the PCB board assembly due to the resistance brought by the larger cross-sectional area of the fixing member. Even under extreme conditions such as severe vibration and frequent shaking, the risk of the digital tube body accidentally detaching from the PCB board assembly can be effectively eliminated, ensuring that the internal circuit connection of the electrical appliance remains stable and reliable.
[0011] In one embodiment, the fixing column and the fixing component are integrally formed. This integral design eliminates potential weak points at the connection points, resulting in a more robust and durable overall structure compared to a separate design. When subjected to external impact, it will not fail due to loosening or cracking of the connection seams, providing continuous and stable support for the digital tube body and ensuring a tight connection with the PCB board assembly. From a manufacturing perspective, this simplifies the production process and reduces component assembly steps. No additional connection processes, such as welding, riveting, or threaded fastening, are required, reducing production costs and avoiding increased product defect rates due to accumulated assembly errors, thus improving production efficiency and product consistency. Simultaneously, the integral molding ensures precise and consistent relative positioning between the fixing column and the fixing component, transmitting force evenly. Even under long-term use and frequent vibration, the digital tube body can maintain an ideal installation state, reducing displacement risks, ensuring the stability of electrical operation, and extending the product's trouble-free operating time.
[0012] In one embodiment, the fixing component and the digital tube body are integrally molded. This integral design eliminates potential seams between the two, significantly improving overall strength. Even under harsh conditions such as external pressure, impact, high temperatures, and humidity, the digital tube body will not shift or detach due to loosening or separation at the joint, providing reliable support and ensuring a secure connection to the PCB board assembly. Simultaneously, the integral molding ensures that the relative position of the fixing component and the digital tube body remains unchanged, resulting in even force distribution. During prolonged operation and frequent start-stop cycles of the appliance, the digital tube body remains stably fixed to the PCB board, reducing the risk of failure and extending product lifespan.
[0013] In one embodiment, there are multiple fixing components arranged circumferentially along the digital tube body, with at least one fixing component located on the inner side of the digital tube body. By arranging multiple fixing components circumferentially along the digital tube body, the digital tube body is ensured to be subjected to uniform force in all directions, effectively resisting external impacts from different angles. Whether it's shaking during appliance handling, collisions during daily use, or material expansion and contraction due to temperature changes, the digital tube body remains stable and tightly adheres to the PCB board assembly. Simultaneously, placing at least one fixing component on the inner side of the digital tube body complements the other fixing components distributed circumferentially along the digital tube body. When the digital tube body is subjected to external force, the inner fixing component provides support from the central area, effectively dispersing stress. For example, when an appliance suffers a side impact, while the outer fixing component resists the impact, the inner component restrains the digital tube body, preventing excessive deformation and displacement, ensuring a tight connection with the PCB board assembly. For long-term stability considerations, the frequent switching on and off of everyday electrical appliances causes thermal expansion and contraction. The internal fixing components can balance the tensile forces caused by these changes, preventing the digital tube body from loosening due to uneven local stress. Moreover, this design makes the overall center of gravity of the digital tube body more stable, reducing shaking and further improving stability under complex operating conditions, ensuring continuous and reliable operation of the appliance.
[0014] In one embodiment, there are multiple fixing components and multiple first fixing holes, with each fixing component and each first fixing hole corresponding one-to-one. By corresponding the multiple fixing components and the multiple first fixing holes, precise installation of the digital tube body on the PCB board assembly can be achieved. Each fixing component has its corresponding first fixing hole as a precise guide for the installation position, allowing operators to quickly and accurately insert the fixing component into the corresponding first fixing hole during assembly. This avoids positional deviations during installation, ensuring that the digital tube is always installed on the PCB board assembly in the correct posture and position, thereby guaranteeing the accuracy and stability of the digital tube display function. Simultaneously, because the multiple fixing components and first fixing holes are evenly distributed, stress can be evenly distributed across multiple contact points of the PCB board assembly, avoiding excessive localized stress.
[0015] In one embodiment, one side of the PCB board assembly is a first mounting surface, and the other side is a second mounting surface. The first mounting surface abuts against the digital tube body, and the fixing component has a first fixing surface. The second mounting surface is connected to the first fixing surface. By tightly abutting the first mounting surface against the digital tube body, a stable supporting foundation is provided for the digital tube body, ensuring that the digital tube body will not sink or shift in the vertical direction, maintaining its accurate installation position. At the same time, the oppositely positioned second mounting surface abuts against the fixing component, reinforcing the connection from another side. The bidirectional clamping structure makes the connection between the digital tube body and the PCB board assembly more secure. When encountering external impact, such as an appliance accidentally falling or being bumped, this double-sided support can effectively disperse the impact force, prevent the digital tube from loosening and falling off, and ensure the stability of the internal circuit connection of the appliance. The double-sided design simplifies the assembly process. Workers only need to place the digital tube body aligning with the first mounting surface, insert the fixing component through the first fixing hole, and use a soldering iron tip to melt the exposed part of the fixing component to form the first fixing surface, which then abuts against the second mounting surface. This allows for quick installation, reducing operational difficulty and minimizing product malfunctions caused by improper assembly. Furthermore, precise double-sided positioning helps improve product consistency, resulting in more stable and reliable electrical performance in mass production, and enhancing overall production efficiency and product quality.
[0016] In one embodiment, the digital tube body includes a digital tube contact surface that abuts against the first mounting surface, and the fixing component is disposed on the digital tube contact surface. By directly abutting the digital tube contact surface against the first mounting surface, the gap between the two is greatly reduced, ensuring that the digital tube body can be accurately and stably attached to the PCB board assembly, avoiding display abnormalities caused by uneven or loose contact surfaces. Simultaneously, the fixing component is disposed on the digital tube contact surface, making force transmission more direct and efficient. When subjected to external force, the fixing component can quickly disperse stress across the entire contact surface, enhancing the overall structure's impact resistance. Furthermore, the tight connection structure effectively prevents dust and moisture, protects internal circuitry, extends the lifespan of electrical components, and improves product reliability.
[0017] In one embodiment, the PCB assembly further includes multiple second fixing holes arranged circumferentially around the PCB assembly. These holes are used to fix the PCB assembly to an external structure. By arranging multiple second fixing holes circumferentially around the PCB assembly, the force is evenly distributed. Whether the appliance experiences vibration or shaking during daily use, or is subjected to bumps during transportation, the PCB board remains remarkably stable and firmly fixed to the external structure. This ensures the stability of the digital display and the entire internal circuitry of the appliance, reducing problems such as poor contact and signal transmission failures caused by PCB board displacement. Simultaneously, the multiple, circumferentially distributed design provides significant flexibility in production and assembly. Different models and specifications of external structures often have different requirements for the fixing position of the PCB assembly, and these second fixing holes can easily meet diverse needs without requiring customized PCB assembly molds, reducing production costs and accelerating product launch. From a maintenance convenience perspective, the PCB assembly is easy to disassemble when deep repairs, replacement of core components, or troubleshooting of circuit faults are required. Maintenance personnel can easily remove PCB board components simply by loosening the corresponding fasteners. This convenient and efficient operation reduces maintenance time, improves after-sales service quality, and enhances the overall competitiveness of the product.
[0018] The second aspect of this application discloses an electrical appliance, which includes: the aforementioned digital tube fixing structure; and an electrical appliance body, wherein the digital tube fixing structure is disposed on the electrical appliance body.
[0019] The second aspect disclosed above discloses an electrical appliance in which a digital tube fixing structure is fixed to the appliance body, ensuring that the digital tube fixing structure and the appliance body form a solid whole. As a key component for information display, the digital tube body, once fixed, can withstand various vibrations and collisions during frequent daily use and transportation, preventing displacement or loosening due to shaking, maintaining accurate and stable display function, ensuring the continuity of internal electrical connections, and reducing the risk of malfunction. At the same time, the tight integration of the digital tube fixing structure with the appliance body avoids the digital tube occupying extra space, making the internal layout of the appliance more compact and orderly. This is of great significance for modern electrical appliances that pursue miniaturization and integrated design, helping to rationally arrange other components within a limited casing and improve the overall performance of the appliance.

[0031] 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.
[0032] 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.
[0033] The following describes, with reference to the accompanying drawings, some embodiments of the digital tube fixing structure and electrical components described herein.
[0034] Example 1
[0035] like Figures 1 to 7 As shown, this embodiment discloses a digital tube fixing structure, characterized in that the digital tube fixing structure includes: a digital tube body 1; a fixing component 2, the fixing component 2 being disposed on the digital tube body 1; a PCB board assembly 3, the PCB board assembly 3 having a first fixing hole 301, one end of the fixing component 2 away from the digital tube body 1 passing through the first fixing hole 301, the part of the fixing component 2 passing through the first fixing hole 301 being connected to the PCB board assembly 3, and the PCB board assembly 3 abutting against the digital tube body 1.
[0036] This application discloses a digital tube fixing structure. First, from the perspective of space utilization, it completely eliminates the drawbacks of traditional digital tube fixing methods. It eliminates the need for additional screw holes for the digital tube body 1, avoiding the problem of increased volume due to reserved hole positions. It also avoids the risk of loosening caused by adhesive aging and cracking when using glue for fixing. The fixing component 2 and the PCB board component 3 are precisely matched, allowing the digital tube body 1 to fit tightly against the PCB board during installation. Furthermore, there is no need to reserve extra space for protruding screw heads, significantly reducing the product thickness. This perfectly aligns with the current trend of thinner and lighter electronic products, easily meeting the compact design requirements of both handheld small appliances and embedded devices with strict space requirements. Second, it revolutionarily simplifies material management and assembly processes. Traditional screw fixing methods require a large number of screws and tools such as screwdrivers, increasing material costs and management difficulty; glue fixing faces issues such as glue shelf life and inconsistent application processes. This structure reduces the complex procurement and inventory management of materials such as screws, lowering costs associated with material stockpiling and loss. Assembly is also convenient and efficient; operators simply pass the fixing component 2 smoothly through the first fixing hole 301 of the PCB board assembly 3, then melt the exposed portion of the fixing component 2 with a soldering iron tip to quickly complete the installation. This eliminates the need for time-consuming screw tightening or long waiting times for adhesive to cure, significantly shortening the production cycle, reducing labor costs, and improving production efficiency. Furthermore, the fixing component 2 and the PCB board assembly 3 interlock to form a stable connection, fundamentally eliminating the risk of loosening or displacement of the digital tube, ensuring long-term stable operation of the electrical appliance, and reducing repair costs due to component loosening. Moreover, the positioning characteristics of the fixing component 2 ensure accurate positioning of the digital tube with each installation, reducing display abnormalities caused by installation deviations, laying a solid foundation for high-quality product operation, and comprehensively improving product reliability and stability.
[0037] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the fixing component 2 includes a fixing column 21 and a fixing member 22. The fixing column 21 is disposed on the digital tube body 1, and the fixing member 22 is disposed on the end of the fixing column 21 away from the digital tube body 1. The fixing column 21 passes through the first fixing hole 301, and the fixing member 22 is connected to the PCB board assembly 3. By directly connecting the fixing column to the digital tube body, the operator only needs to align the fixing column 21 with the first fixing hole 301 of the PCB board assembly 3 and insert it, and then use a soldering iron tip to melt the exposed part of the fixing component 2 to form the fixing member 22. Compared with the traditional complex fixing method, the operation steps are greatly simplified, and even novice workers can quickly get started, greatly improving the assembly speed and reducing the manpower input and time cost of the production line. The fixing member 22 is located at the end of the fixing column 21 away from the digital tube body 1 and abuts against the PCB board assembly 3, forming a stable three-point support structure. This design makes the connection between the digital tube body 1 and the PCB board assembly 3 more secure, effectively resisting vibrations and impacts during daily use of the appliance, as well as bumps during transportation. This greatly reduces the risk of loosening and displacement of the digital tube body 1, ensuring stable internal circuit connections, reducing malfunctions caused by poor contact, and extending the appliance's lifespan. At the same time, given the slim design of the fixing post 21, which occupies very little space compared to the large screw holes required by traditional screw fixings, the peripheral layout of the digital tube body 1 is more compact. This leaves more space for other internal components, facilitating miniaturization and multi-functional upgrades, meeting the growing consumer demand for high-performance, small-sized appliances, and further enhancing the product's market competitiveness.
[0038] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fixing member 22 includes a first fixing surface 221 and a second fixing surface 222. The first fixing surface 221 is disposed on the fixing column 21 and abuts against the PCB board assembly 3. The second fixing surface 222 is disposed opposite to the first fixing surface 221. By tightly attaching the first fixing surface 221 to the PCB board assembly 3, a solid support point is provided for the digital tube body 1, ensuring the stability of the digital tube body 1 in the vertical direction and effectively preventing sinking or displacement caused by gravity or slight shaking. When the electrical appliance encounters accidental collisions, drops, or vibrations caused by frequent plugging and unplugging of external devices, this fixing structure can firmly lock the digital tube body 1, keeping it stable in the correct position, ensuring the continuity and stability of the internal electrical connection, and reducing the probability of failure. The first fixing surface 221 is directly connected to the fixing column 21, ensuring the initial accuracy of the installation. The operator only needs to insert the fixing column 21 into the hole, and then use a soldering iron tip to melt the part of the fixing component 2 that is exposed to form the first fixing surface 221 and the second fixing surface 222. This reduces the thickness of the product, simplifies the operation process, improves the installation efficiency, and ensures the final installation quality, providing strong support for large-scale and efficient production.
[0039] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fixing member 22 is a plastic part, and the fixing member 22 is heat-fused to the PCB board assembly 3. By heat-fused to the fixing member 22 and the PCB board assembly 3, the connection between the fixing member 22 and the PCB board assembly 3 is seamless, which can effectively avoid loosening caused by long-term use compared to mechanical connection methods. After heat fusion, the plastic part can fit well against the surface of the PCB board assembly 3, and can maintain the stability of the digital tube when subjected to external impact, such as electrical collision or vibration, reducing the risk of digital tube displacement or detachment, thereby ensuring the normal display function of the electrical appliance.
[0040] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the fixing member 22 is made by hot melting. By making the fixing member 22 by hot melting, the fixing member 22 can be melted and deformed by using a soldering iron tip, and finally completely adhered to the PCB board assembly 3. On the one hand, this ensures that the digital tube body 1 can be firmly fixed to the PCB board assembly 3. On the other hand, compared with the traditional fixing method, this fixing method can effectively avoid the problem of the digital tube body 1 increasing in size due to the reserved ear position. It can also avoid the hidden danger of the digital tube loosening caused by the aging and cracking of the adhesive when using glue fixing. Furthermore, it can avoid the extra space reserved by the protruding screw head, reduce the space occupied by the overall structure of the digital tube, and facilitate the miniaturization of electrical equipment.
[0041] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of the fixing member 22 is larger than the cross-sectional area of the first fixing hole 301. By setting the cross-sectional area of the fixing member 22 to be larger than the cross-sectional area of the first fixing hole 301, the digital tube body 1 is firmly fixed on the PCB board assembly 3 by the resistance brought by the larger cross-sectional area of the fixing member 22. Even in extreme working conditions such as severe vibration and frequent shaking, the risk of the digital tube body 1 accidentally falling off the PCB board assembly 3 can be effectively eliminated, ensuring that the internal circuit connection of the electrical appliance is always stable and reliable.
[0042] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that the fixing column 21 and the fixing member 22 are integrally formed. By designing the fixing column 21 and the fixing member 22 as an integral unit, the weak points that may exist in the connection part are eliminated, and the overall structure is more robust and durable compared to the split design. When subjected to external impact, it will not fail to fix due to loosening or cracking of the connection gap, providing continuous and stable support for the digital tube body 1 and ensuring its tight connection with the PCB board assembly 3. From a manufacturing perspective, the production process is simplified and the component assembly steps are reduced. No additional connection processes, such as welding, riveting, or thread fastening, are required, which reduces production costs and avoids the problem of increased product defect rate caused by the accumulation of assembly errors, thereby improving production efficiency and product consistency. At the same time, the integral molding ensures that the relative position between the fixing column and the fixing member remains accurate and unchanged, and the force is transmitted evenly. Under long-term use and frequent vibration environment, the digital tube body 1 can always maintain an ideal installation state, reduce the risk of displacement, ensure the stability of electrical operation, and extend the product's trouble-free operation time.
[0043] like Figure 3 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the fixing component 2 and the digital tube body 1 are integrally molded. By designing the fixing component 2 and the digital tube body 1 as an integral mold, the possible joint gaps between the two are eliminated, resulting in a significant improvement in overall strength. Facing external pressure, collisions, and even harsh environments such as high temperature and humidity, the digital tube body 1 will not shift or fall off due to loosening or separation at the joint, always providing a reliable support for the digital tube body 1 and ensuring its stable connection with the PCB board assembly 3. At the same time, the integral molding ensures that the relative position of the fixing component 2 and the digital tube body 1 remains unchanged, and the force is evenly distributed. During long-term operation and frequent start-stop of the electrical appliance, the digital tube body 1 can be stably fixed on the PCB board, reducing the risk of failure and extending the product's service life.
[0044] As shown in Figure *3, in addition to the features of the above embodiments, this embodiment further specifies that: the number of fixing components 2 is multiple, the multiple fixing components 2 are arranged along the circumference of the digital tube body 1, and at least one fixing component 2 is arranged on the inner side of the digital tube body 1. By arranging multiple fixing components 2 along the circumference of the digital tube body 1, it is ensured that the digital tube body 1 is subjected to uniform force in all directions, and can effectively resist external force impacts from different angles. Whether it is shaking during the handling of electrical appliances, collisions during daily use, or material expansion and contraction caused by temperature changes, the digital tube body 1 can remain stable and tightly fit with the PCB board assembly 3. At the same time, at least one fixing component 2 is arranged on the inner side of the digital tube body 1, which complements the other fixing components 2 distributed along the circumference of the digital tube body 1. When the digital tube body 1 is subjected to external force, the inner fixing component 2 can provide support from the central area and effectively disperse stress. For example, when the electrical appliance is subjected to a side impact, while the outer fixing component 2 resists the impact, the inner component restrains the digital tube body 1, preventing it from excessive deformation and displacement, and ensuring the tightness of the connection with the PCB board assembly 3. From the perspective of long-term stability, the frequent switching on and off of everyday electrical appliances causes thermal expansion and contraction. The inner fixing component 2 can balance the tensile force caused by this change internally, preventing the digital tube body 1 from loosening due to uneven local stress. Moreover, this design makes the overall center of gravity of the digital tube body 1 more stable, reduces shaking, and further improves stability under complex operating conditions, ensuring continuous and reliable operation of the electrical appliance.
[0045] like Figure 2 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of fixing components 2 is multiple, the number of first fixing holes 301 is multiple, and the multiple fixing components 2 and the multiple first fixing holes 301 are arranged in a one-to-one correspondence. By arranging the multiple fixing components 2 and the multiple first fixing holes 301 in a one-to-one correspondence, the digital tube body 1 can be accurately installed on the PCB board assembly 3. Each fixing component 2 has its corresponding first fixing hole 301 as a precise guide for the installation position, allowing the operator to quickly and accurately insert the fixing component 2 into the corresponding first fixing hole 301 during the assembly process. This avoids positional deviations during the installation process, ensuring that the digital tube is installed on the PCB board assembly 3 in the correct posture and position each time, thereby ensuring the accuracy and stability of the digital tube display function. At the same time, since the multiple fixing components 2 and the first fixing holes 301 are evenly distributed, the stress can be evenly distributed on multiple contact points of the PCB board assembly 3, avoiding excessive local stress.
[0046] like Figure 4 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one side of the PCB board assembly 3 is a first mounting surface 31, and the other side of the PCB board assembly 3 is a second mounting surface 32. The first mounting surface 31 abuts against the digital tube body 1, and the fixing assembly 2 is provided with a first fixing surface 221. The second mounting surface 32 is connected to the first fixing surface 221. By tightly abutting the first mounting surface 31 against the digital tube body 1, a stable support foundation is provided for the digital tube body 1, ensuring that the digital tube body 1 will not sink or shift in the vertical direction, maintaining its accurate installation position. At the same time, the oppositely arranged second mounting surface 32 abuts against the fixing assembly 2, reinforcing the connection from the other side. The bidirectional clamping structure makes the connection between the digital tube body 1 and the PCB board assembly 3 more secure. When encountering external impact, such as when an appliance is accidentally dropped or collided, this double-sided support can effectively disperse the impact force, prevent the digital tube from loosening and falling off, and ensure the stability of the internal circuit connection of the appliance. The double-sided design simplifies the assembly process. Workers only need to place the digital tube body 1 aligning with the first mounting surface 31, with the fixing component 2 passing through the first fixing hole 301. By using a soldering iron tip to melt the exposed portion of the fixing component 2 to form the first fixing surface 221, which then abuts against the second mounting surface 32, installation can be completed quickly. This reduces operational difficulty and minimizes product malfunctions caused by improper assembly. Furthermore, precise double-sided positioning helps improve product consistency, making the performance of mass-produced electrical appliances more stable and reliable, thereby improving overall production efficiency and product quality.
[0047] 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 digital tube body 1 includes a digital tube contact surface 11, which abuts against the first mounting surface 31, and the fixing component 2 is disposed on the digital tube contact surface 11. By directly abutting the digital tube contact surface 11 against the first mounting surface 31, the gap between the two is greatly reduced, ensuring that the digital tube body 1 can be accurately and stably attached to the PCB board assembly 3, avoiding display abnormalities caused by unevenness or looseness of the contact surface. At the same time, the fixing component 2 is disposed on the digital tube contact surface 11, making the force transmission more direct and efficient. When subjected to external force, the fixing component 2 can quickly disperse the stress to the entire contact surface, enhancing the impact resistance of the overall structure. In addition, the tight connection structure can also effectively prevent dust and moisture, protect the internal circuit, extend the service life of electrical appliances, and improve product reliability.
[0048] like Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the PCB board assembly 3 is also provided with a plurality of second fixing holes 302, which are arranged along the circumference of the PCB board assembly 3. These multiple second fixing holes 302 are used to fix the PCB board assembly 3 to the external structure. By arranging multiple second fixing holes 302 along the circumference of the PCB board assembly 3, the force is evenly distributed. Whether the electrical appliance experiences vibration or shaking during daily use, or is subjected to bumps during transportation, the PCB board remains quite stable and firmly fixed to the external structure, thereby ensuring the stability of the digital tube and the entire internal circuitry of the electrical appliance, and reducing problems such as poor contact and signal transmission failures caused by PCB board displacement. At the same time, the multiple, circumferentially distributed design provides great flexibility for production and assembly. Different models and specifications of external structures often have different requirements for the fixing position of the PCB board assembly, and these second fixing holes 302 can easily meet diverse needs without the need to customize PCB board assembly molds, reducing production costs and accelerating the product's time to market. From a maintenance convenience perspective, the PCB board assembly is easy to disassemble when in-depth electrical repairs, replacement of core components, or troubleshooting of circuit faults are required. Maintenance personnel can easily remove the PCB board assembly simply by loosening the corresponding fasteners, making the operation convenient and efficient, reducing maintenance time, improving after-sales service quality, and enhancing the overall competitiveness of the product.
[0049] Example 2
[0050] like Figures 1 to 7 As shown, this embodiment discloses an electrical appliance, including: the aforementioned digital tube fixing structure; and an electrical appliance body, wherein the digital tube fixing structure is disposed on the electrical appliance body.
[0051] The second aspect of this application discloses an electrical appliance in which a digital tube fixing structure is fixed to the appliance body, ensuring that the digital tube fixing structure and the appliance body form a solid whole. As a key component for information display, the digital tube body 1, once fixed, can withstand various vibrations and collisions during frequent daily use and transportation of the appliance, preventing displacement or loosening due to shaking, maintaining accurate and stable display function, ensuring the continuity of internal electrical connections, and reducing the risk of malfunction. At the same time, the tight integration of the digital tube fixing structure with the appliance body avoids the digital tube occupying extra space, making the internal layout of the appliance more compact and orderly. This is of great significance for modern electrical appliances that pursue miniaturization and integrated design, helping to rationally arrange other components within a limited casing and improve the overall performance of the appliance.
