Description

Technical Field

[0001] This utility model relates to the field of thermoforming technology, specifically to a novel thermoformed product structure. Background Technology

[0002] Thermoforming is specifically applied in industries such as automobile manufacturing and machinery manufacturing where parts need to be manufactured through thermoforming processes. It is particularly useful for the molding and processing of relatively small thermoformed parts and the design and use of supporting molds. It represents a direction for technological improvement in this field to optimize production processes, improve mold utilization, and balance product performance and production economy.

[0003] In traditional thermoforming processes, small parts typically require a separate mold cavity for each part. This design fails to fully utilize the internal space of the thermoforming mold, resulting in wasted mold space and often limiting the number of small parts that can be accommodated in a single mold due to space constraints. Furthermore, the individual production of each small part leads to a significant increase in press strokes, with each thermoforming operation processing only a small number or even a single part. This reduces production efficiency per unit time and increases energy consumption during press operation, further raising overall operating and manufacturing costs. Therefore, a novel thermoforming product structure is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel thermoforming product structure that solves the problem that typically requires designing a separate mold cavity for each part. This design approach makes it impossible to fully utilize the space inside the thermoforming mold, resulting in a waste of mold space and often making it difficult to fit a larger number of small parts into a single mold due to the limitations of the mold space itself.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel thermoformed product structure, comprising:

[0006] The first material sheet and the second material sheet disposed outside the first material sheet, and a connecting material sheet is added above the first material sheet and the second material sheet, and a material sheet positioning hole is opened in the center of the upper surface of the connecting material sheet, and the lower surface of the connecting material sheet is connected to the corresponding upper surface of the first material sheet and the second material sheet on both sides.

[0007] Solder joints are provided around the upper surface of the connecting sheet, and the connecting sheet is connected to the first sheet and the second sheet through the solder joints;

[0008] The thermal expansion compensation notch is located on both sides of the center of the upper surface of the connecting material sheet, and the thermal expansion compensation notch is U-shaped.

[0009] First, structural components are prepared, and the first sheet, the second sheet, and the connecting sheet are obtained after molding. The center of the upper surface of the connecting sheet has a pre-drilled sheet positioning hole, and the two sides of the center of the upper surface of the connecting sheet have pre-drilled thermal expansion compensation notches with an overall U-shaped design.

[0010] Next, the components are assembled and positioned. The second piece is placed outside the first piece, and the connecting piece is placed above the first and second pieces. The position of the connecting piece is adjusted so that the lower surface of the connecting piece is aligned with the corresponding positions of the upper surface of the first and second pieces, respectively.

[0011] Then, the connection and fixing operation is carried out. By setting the welding points around the upper surface of the connecting material sheet, the connecting material sheet is connected to the first material sheet and the second material sheet. This makes the connecting material sheet form a stable connection with the first and second material sheets through the welding points. At the same time, it ensures that the two sides of the lower surface of the connecting material sheet are in close contact with the corresponding parts of the upper surface of the first and second material sheets, further improving the connection stability.

[0012] When entering the subsequent processing stage, the positioning hole at the center of the upper surface of the connecting sheet is used to coordinate the new thermoforming product structure with the positioning mechanism of the processing equipment to achieve precise positioning of the product during the processing, ensuring the smooth progress of subsequent thermoforming and other processing steps;

[0013] During the processing and use of this new thermoformed product structure, if the product expands or contracts due to changes in ambient temperature, the U-shaped thermal expansion compensation notches on both sides of the center of the upper surface of the connecting sheet will absorb the stress caused by thermal expansion and contraction between the first sheet, the second sheet and the connecting sheet through their own deformation, thus preventing loose connections or structural cracking between the sheets and maintaining the integrity of the product structure.

[0014] Preferably, fixing plates are installed at corresponding positions on the upper surfaces of the first and second sheet materials, and serrated blocks are added to the inner sides of the fixing plates. The fixing plates enhance the structural strength of the corresponding positions of the first and second sheet materials, preventing deformation of the corresponding areas on the upper surfaces of the first and second sheet materials due to stress during subsequent assembly or use. The serrated blocks added to the inner sides of the fixing plates provide a mechanical meshing basis for subsequent connections with other components. The meshing effect of the serrated structure improves the stability of subsequent connections and prevents relative slippage of connected components. At the same time, the serrated shape of the serrated blocks increases the contact area, disperses the stress, reduces local stress concentration, and extends the service life of the overall structure.

[0015] Preferably, positioning grooves are formed on the upper surfaces of the first and second sheet pieces respectively, and these positioning grooves are located on the front and back sides of the corresponding fixing plates. An iron positioning block is installed within the inner cavity of the positioning groove. The positioning grooves provide a precise installation positioning reference for the iron positioning block, preventing positional shifts during installation and ensuring its installation accuracy. The positioning grooves, located on the front and back sides of the fixing plate, create a collaborative positioning effect with the fixing plate, further improving the overall positioning accuracy of the first and second sheet pieces. The iron positioning blocks provide a foundation for subsequent cooperation with magnetic components, enabling rapid positioning and connection through magnetic attraction, simplifying the assembly process. Furthermore, the high strength of the iron material enhances the structural stability of the positioning parts, preventing damage to the positioning components from affecting the overall assembly effect.

[0016] Preferably, both sides of the connecting sheet are provided with serrated grooves, and the serrated grooves mesh with the corresponding serrated blocks. The meshing of the serrated grooves on both sides of the connecting sheet with the corresponding serrated blocks can achieve mechanical limiting between the connecting sheet and the first and second sheets, effectively preventing relative movement of the connecting sheet in the horizontal direction, improving the stability of the connection between the three, and the meshing structure design facilitates quick positioning and installation, reduces assembly time, and improves assembly efficiency. The large meshing contact area between the serrated grooves and the serrated blocks can evenly distribute the force to multiple teeth, reducing the risk of local stress concentration, avoiding damage to the connection parts due to excessive force, and extending the service reliability of the overall structure.

[0017] Preferably, positioning seats are installed on both the front and back sides of the connecting sheet, and a permanent magnet block is added to the center of the inner cavity of each positioning seat. The permanent magnet block is magnetically connected to the corresponding iron positioning block. The positioning seats installed on the connecting sheet provide a stable mounting carrier for the permanent magnet block, ensuring that the permanent magnet block can be firmly fixed on the connecting sheet and preventing it from falling off during use. The magnetic connection between the permanent magnet block and the corresponding iron positioning block can position and fix the connecting sheet from the vertical direction. It works in conjunction with the horizontal limiting structure of the serrated groove and serrated block to achieve omnidirectional positioning of the connecting sheet, further improving the connection reliability of the overall structure. The magnetic connection method does not require additional fasteners, simplifying the assembly process, reducing assembly difficulty, and facilitating subsequent disassembly and maintenance. The magnetic force between the permanent magnet block and the iron positioning block is stable and can maintain the connection effect for a long time, avoiding loosening of the connection due to external factors such as vibration, and improving the overall structural stability.

[0018] Preferably, the upper surface of the solder joint is provided with heat-conducting grooves around the perimeter, and the heat-conducting grooves are designed as concentric rings. A honeycomb hollow array is provided on both the front and rear ends of the upper surface of the connecting sheet, and heat-insulating protrusions are installed on both the front and rear ends of the upper surface of the connecting sheet. The heat-insulating protrusions are designed as a hemispherical shape. The concentric ring-shaped heat-conducting grooves around the upper surface of the solder joint significantly increase the heat dissipation area, accelerate the dissipation of heat generated during operation, prevent performance degradation due to localized overheating, and effectively extend the service life of the solder joint. The honeycomb perforated array on both the front and rear ends of the center of the connecting sheet reduces the overall weight of the connecting sheet while maintaining structural strength, thus lowering the overall structural load. Simultaneously, the honeycomb structure provides excellent heat dissipation, assisting the heat-conducting grooves in heat dissipation and further improving the overall structure's heat dissipation efficiency. The hemispherical heat-insulating protrusions installed at the front and rear ends of the center of the connecting sheet reduce the transfer of external heat to the central area of ​​the connecting sheet, protecting components in the central area from high temperatures. The hemispherical structure also distributes stress evenly, preventing damage to the heat-insulating protrusions due to excessive localized stress, thereby improving their service life and insulation effect.

[0019] Compared with the prior art, this utility model provides a novel thermoformed product structure, which has the following beneficial effects:

[0020] This novel thermoforming product structure, by connecting two or more sheets together through spot welding of sheet metal plates before thermoforming, effectively solves the problems of space waste and high costs caused by designing a separate cavity for small parts in traditional thermoforming processes. It can make full use of the thermoforming mold space, eliminating the need to set up a separate cavity for each small part, avoiding the situation where more parts cannot be placed due to limited mold space. This reduces the need to develop multiple sets of thermoforming molds to accommodate more parts, thus reducing the cost investment in mold design and manufacturing. During the production process, due to the reduction in the number of mold sets, and avoiding a significant increase in the number of press strokes when producing a single part, multiple parts connected by spot welding of sheet metal plates can be processed in a single thermoforming operation, improving the production efficiency per unit time, correspondingly reducing the energy consumption and operating costs in the press production process, and further reducing the overall production and manufacturing costs.

[0021] The arrangement of positioning holes and welding points for sheet metal and connecting sheet metal can be expanded to more modes laterally, not limited to parts of a specific type, thickness or shape. It can provide a reference for the thermoforming design of more parts, improve the flexibility of thermoforming production technology in dealing with product diversity and customization needs, and help the manufacturing industry better balance production economy and market adaptability while ensuring the performance requirements of high strength and lightweight products.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution, a novel thermoformed product structure, including: (Please refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The first material sheet 1 and the second material sheet 2 disposed outside the first material sheet 1, and a connecting material sheet 3 is added above the first material sheet 1 and the second material sheet 2, and a material sheet positioning hole 16 is opened in the center of the upper surface of the connecting material sheet 3, and the lower surface of the connecting material sheet 3 is connected to the corresponding upper surface of the first material sheet 1 and the second material sheet 2 on both sides.

[0031] Solder joint 11 is provided around the upper surface of the connecting sheet 3, and the connecting sheet 3 is connected to the first sheet 1 and the second sheet 2 through the solder joint 11;

[0032] Thermal expansion compensation notches 14 are provided on both sides of the center position of the upper surface of the connecting material sheet 3, and the thermal expansion compensation notches 14 are U-shaped in design.

[0033] First, structural components are prepared, and the first sheet 1, the second sheet 2 and the connecting sheet 3 are obtained after molding. The center of the upper surface of the connecting sheet 3 has a pre-opened sheet positioning hole 16, and the two sides of the center of the upper surface of the connecting sheet 3 have pre-opened thermal expansion compensation notches 14 with an overall U-shaped design.

[0034] Next, the components are assembled and positioned. The second sheet 2 is placed outside the first sheet 1, and the connecting sheet 3 is placed above the first sheet 1 and the second sheet 2. The position of the connecting sheet 3 is adjusted so that the lower surface of the connecting sheet 3 is aligned with the corresponding positions of the upper surface of the first sheet 1 and the upper surface of the second sheet 2.

[0035] Then, a connection and fixing operation is performed. By setting the welding points 11 around the upper surface of the connecting sheet 3, the connecting sheet 3 is connected to the first sheet 1 and the connecting sheet 3 is connected to the second sheet 2. This makes the connecting sheet 3 form a stable connection with the first sheet 1 and the second sheet 2 through the welding points 11. At the same time, it ensures that the two sides of the lower surface of the connecting sheet 3 are in close contact with the corresponding parts of the upper surface of the first sheet 1 and the second sheet 2, further improving the connection stability.

[0036] When entering the subsequent processing stage, the positioning hole 16 at the center of the upper surface of the connecting material sheet 3 is used to coordinate the new thermoforming product structure with the positioning mechanism of the processing equipment to achieve precise positioning of the product during the processing, ensuring the smooth progress of subsequent thermoforming and other processing steps;

[0037] During the process of completing the processing and putting into use of this new thermoformed product structure, if the product expands and contracts due to changes in ambient temperature, the U-shaped thermal expansion compensation gaps 14 on both sides of the center position on the upper surface of the connecting sheet 3 will absorb the stress caused by thermal expansion and contraction between the first sheet 1, the second sheet 2 and the connecting sheet 3 through their own deformation, so as to avoid loose connection or structural cracking between the sheets and maintain the integrity of the product structure.

[0038] This structure forms a multi-directional and stable connection by attaching the lower surfaces of the connecting sheet 3 to the corresponding upper surfaces of the first sheet 1 and the second sheet 2, and fixing it with the welding points 11 around the upper surface of the connecting sheet 3. This effectively enhances the connection strength between the first sheet 1, the second sheet 2 and the connecting sheet 3, and can prevent the separation of the sheets during processing, handling or actual use, thus ensuring the long-term stability of the overall structure of the product.

[0039] The positioning hole 16 at the center of the upper surface of the connecting sheet 3 serves as the positioning reference during product processing and installation, eliminating the need for additional positioning components. This simplifies the positioning operation process and accurately guides the product's interaction with external equipment, reducing positioning deviations and improving the processing accuracy and final product quality of subsequent thermoforming and other processing steps.

[0040] The U-shaped thermal expansion compensation notch 14 has good deformation capability. Its opening position matches the stress concentration area of ​​the connecting material sheet 3. When the product is affected by thermal expansion and contraction, the thermal expansion compensation notch 14 can actively absorb the stress between the first material sheet 1, the second material sheet 2 and the connecting material sheet 3, effectively alleviating the structural deformation or internal stress concentration problems that may be caused by the difference in thermal expansion and contraction coefficients of different material sheets, avoiding defects such as cracking and deformation of the product, and extending the service life of the product.

[0041] The structure features a simple and tightly fitted first sheet 1, second sheet 2, connecting sheet 3 welding point 11, thermal expansion compensation notch 14, and sheet positioning hole 16. It can achieve core functions such as connection, positioning, and thermal expansion compensation without the need for complex additional structures. While ensuring product performance, it reduces the difficulty of component processing and overall assembly, which is conducive to improving production efficiency.

[0042] Please see Figure 2 and Figure 3Fixing plates 4 are installed on the corresponding positions of the upper surfaces of the first sheet 1 and the second sheet 2, and serrated blocks 5 are added to the inner sides of the fixing plates 4. First, the positions of the first sheet 1 and the second sheet 2 are calibrated to ensure that they are on the preset assembly reference line. Subsequently, fixing plates 4 are installed at corresponding positions on the upper surfaces of the first sheet 1 and the second sheet 2 using bolts or welding. During installation, positioning tools are needed to ensure the levelness and positional accuracy of the fixing plates 4 to avoid misalignment. After the fixing plates 4 are installed, the corresponding areas on their inner surfaces are treated to remove impurities and burrs. Then, the serrated blocks 5 are added to the inner surfaces of the fixing plates 4 by welding or bonding. After addition, the connection between the serrated blocks 5 and the fixing plates 4 must be checked to ensure there is no looseness. The fixing plates 4 enhance the structural strength of the corresponding positions of the first sheet 1 and the second sheet 2, preventing deformation of the corresponding areas on the upper surfaces of the first sheet 1 and the second sheet 2 due to stress during subsequent assembly or use. The serrated blocks 5 added to the inner surfaces of the fixing plates 4 provide a mechanical meshing basis for subsequent connections with other components. The meshing effect of the serrated structure improves the stability of subsequent connections and prevents relative sliding of connected components. At the same time, the serrated shape of the serrated blocks 5 increases the contact area, disperses the force, reduces local stress concentration, and extends the service life of the overall structure.

[0043] Positioning grooves 6 are formed at corresponding positions on the upper surfaces of the first sheet 1 and the second sheet 2, and the positioning grooves 6 are located on the front and back sides of the corresponding fixing plate 4. An iron positioning block 7 is installed inside the positioning groove 6. After the fixing plate 4 on the upper surfaces of the first sheet 1 and the second sheet 2 is installed, the position of the positioning groove 6 is determined according to the position of the fixing plate 4, ensuring that the positioning groove 6 is located on the front and back sides of the corresponding fixing plate 4. The positioning grooves 6 are formed at corresponding positions on the upper surfaces of the first sheet 1 and the second sheet 2 using a milling machine. During the forming process, the depth and width of the positioning groove 6 must be controlled to ensure that its dimensions meet the design requirements. After the positioning groove 6 is machined, its inner cavity is cleaned to remove machining debris. Then, the iron positioning block 7 is placed inside the positioning groove 6, and its position is adjusted so that it completely fits the inner wall of the positioning groove 6. Finally, the iron positioning block 7 is fixed by bonding or interference fit. The positioning groove 6 provides a precise installation positioning reference for the iron positioning block 7, preventing positional displacement during installation and ensuring installation accuracy. Located on the front and back of the fixing plate 4, the positioning groove 6 works in synergy with the fixing plate 4 to further improve the overall positioning accuracy of the first piece 1 and the second piece 2. The iron positioning block 7 provides a foundation for subsequent cooperation with magnetic components, enabling rapid positioning and connection through magnetic attraction, simplifying the assembly process. Furthermore, the high strength of the iron material enhances the structural stability of the positioning area, preventing damage to the positioning components from affecting the overall assembly effect.

[0044] Please see Figure 4 Both sides of the connecting sheet 3 are provided with serrated grooves 10, and the serrated grooves 10 mesh with the corresponding serrated blocks 5. First, the connecting sheet 3 is pre-treated to remove the oxide layer and impurities on the surface. According to the tooth shape and distance of the serrated blocks 5 on the first sheet 1 and the second sheet 2, serrated grooves 10 are opened on the corresponding positions on both sides of the connecting sheet 3 by milling or punching. During the processing, it is necessary to ensure that the tooth shape and distance of the serrated grooves 10 are completely matched with the corresponding serrated blocks 5. After the serrated grooves 10 are processed, the connecting sheet 3 is transported to the preset assembly position between the first sheet 1 and the second sheet 2. The posture of the connecting sheet 3 is adjusted so that the serrated grooves 10 on both sides of the connecting sheet 3 are aligned with the serrated blocks 5 on the inner side of the fixing plate 4 on the first sheet 1 and the second sheet 2, respectively. The connecting sheet 3 is slowly pushed so that the serrated grooves 10 and the serrated blocks 5 gradually mesh. Gradually mesh until the two parts are fully engaged. Finally, check for gaps or misalignments in the meshing area to ensure tight meshing. The serrated grooves 10 on both sides of the connecting material piece 3 mesh with the corresponding serrated blocks 5, which can achieve mechanical limiting between the connecting material piece 3 and the first material piece 1 and the second material piece 2, effectively preventing relative movement of the connecting material piece 3 in the horizontal direction, improving the stability of the connection between the three. The meshing structure design facilitates quick positioning and installation, reduces assembly time, and improves assembly efficiency. The meshing contact area between the serrated groove 10 and the serrated block 5 is large, which can evenly distribute the force to multiple teeth, reduce the risk of local stress concentration, avoid damage to the connection part due to excessive force, and extend the service reliability of the overall structure.

[0045] Positioning seats 8 are installed on both the front and back sides of the connecting sheet 3, and a permanent magnet block 9 is added to the center of the inner cavity of each positioning seat 8. The permanent magnet block 9 is magnetically connected to the corresponding iron positioning block 7. After the connecting sheet 3 is processed, according to the positions of the iron positioning blocks 7 on the first sheet 1 and the second sheet 2, the installation positions of the positioning seats 8 are marked on the corresponding positions on the front and back sides of the connecting sheet 3. The positioning seats 8 are installed at the corresponding marked positions on the connecting sheet 3 by welding or bolting. During the installation process, the verticality and positional accuracy of the positioning seats 8 must be ensured. After the positioning seats 8 are installed, their inner cavities are cleaned to remove impurities. Then, the permanent magnet block 9 is placed in the center of the inner cavity of the positioning seat 8, and the posture of the permanent magnet block 9 is adjusted to ensure that its magnetic pole direction meets the magnetic attraction requirements. Finally, the positioning seats are connected by gluing or snapping. The permanent magnet block 9 is fixed in the inner cavity of the positioning seat 8. After the serrated groove 10 of the connecting material sheet 3 engages with the serrated block 5, the upper and lower positions of the connecting material sheet 3 are adjusted so that the permanent magnet block 9 in the positioning seat 8 is close to the corresponding iron positioning block 7. The magnetic attraction between the permanent magnet block 9 and the iron positioning block 7 is used to further fix the connecting material sheet 3 in the preset position. Finally, the firmness of the magnetic connection is checked to ensure that there is no loosening. The positioning seat 8 installed on the connecting material sheet 3 provides a stable mounting carrier for the permanent magnet block 9, ensuring that the permanent magnet block 9 can be firmly fixed on the connecting material sheet 3 and preventing the permanent magnet block 9 from falling off during use. The magnetic connection between the permanent magnet block 9 and the corresponding iron positioning block 7 can position and fix the connecting piece 3 in the vertical direction. It works in conjunction with the horizontal limiting structure of the serrated groove 10 and the serrated block 5 to achieve all-round positioning of the connecting piece 3, further improving the connection reliability of the overall structure. The magnetic connection method does not require additional fasteners, which simplifies the assembly process, reduces the assembly difficulty, and facilitates subsequent disassembly and maintenance. The magnetic attraction between the permanent magnet block 9 and the iron positioning block 7 is stable and can maintain the connection effect for a long time, avoiding loosening of the connection due to external factors such as vibration, and improving the overall structural stability.

[0046] Please see Figure 5 and Figure 6Heat-conducting grooves 12 are formed around the upper surface of the weld point 11, and the heat-conducting grooves 12 are designed as concentric rings. A honeycomb perforated array 13 is formed on both the front and rear ends of the center of the upper surface of the connecting sheet 3, and heat-insulating protrusions 15 are installed on the front and rear ends of the center of the upper surface of the connecting sheet 3. The heat-insulating protrusions 15 are hemispherical in shape. After connecting the first sheet 1, the second sheet 2, and the connecting sheet 3 to form the weld point 11, the upper surface of the weld point 11 is cleaned to remove welding slag and impurities. According to the design requirements of the concentric rings, heat-conducting grooves 12 are formed at corresponding positions around the upper surface of the weld point 11 using milling equipment. During processing, the annular distance and depth of the heat-conducting grooves 12 need to be controlled to ensure uniform dimensions. After the heat-conducting grooves 12 are processed, the upper surface of the connecting sheet 3 is marked to determine the installation positions of the honeycomb perforated array 13 and the heat-insulating protrusions 15. The honeycomb perforated array 13 is located on both the front and rear ends of the center of the upper surface of the connecting sheet 3, and the heat insulation protrusions 15 are located on the front and rear ends of the center of the upper surface of the connecting sheet 3. The honeycomb perforated array 13 is cut at the marked positions on the connecting sheet 3 using a laser cutting device, ensuring that the shape and arrangement of the holes in the honeycomb perforated array 13 meet the design requirements. The hemispherical heat insulation protrusions 15 are installed at the corresponding marked positions on the connecting sheet 3 by bonding or welding. After installation, the processing and installation of the heat conduction groove 12, the honeycomb perforated array 13 and the heat insulation protrusions 15 are checked. The assembly quality is ensured to be free of processing defects and installation deviations. The concentric ring heat-conducting grooves 12 on the upper surface of the solder joint 11 can significantly increase the heat dissipation area of ​​the solder joint 11, accelerate the dissipation of heat generated by the solder joint 11 during operation, prevent the performance of the solder joint 11 from deteriorating due to local overheating, and effectively extend the service life of the solder joint 11. The honeycomb hollow array 13 on both the front and rear ends of the center of the upper surface of the connecting sheet 3 can reduce the overall weight of the connecting sheet 3 and reduce the load on the overall structure while ensuring the structural strength of the connecting sheet 3. At the same time, the honeycomb structure has good heat dissipation performance and can assist the heat-conducting grooves 12 in heat dissipation, further improving the heat dissipation efficiency of the overall structure. The hemispherical heat-insulating protrusions 15 installed on the front and rear ends of the center of the upper surface of the connecting sheet 3 can reduce the transfer of external heat to the central area of ​​the connecting sheet 3, protect the components in the central area of ​​the connecting sheet 3 from high temperature. At the same time, the hemispherical structure distributes the force evenly, which can disperse the external pressure and prevent the heat-insulating protrusions 15 from being damaged due to excessive local force, thereby improving the service life and heat insulation effect of the heat-insulating protrusions 15.

[0047] This solution: First, prepare the structural components and obtain the first sheet 1, the second sheet 2 and the connecting sheet 3 after molding. The center of the upper surface of the connecting sheet 3 has a pre-opened sheet positioning hole 16, and the two sides of the center of the upper surface of the connecting sheet 3 have pre-opened thermal expansion compensation notches 14 with an overall U-shaped design.

[0048] The second sheet 2 is placed on the outside of the first sheet 1, and the connecting sheet 3 is placed above the first sheet 1 and the second sheet 2. The position of the connecting sheet 3 is adjusted so that the two sides of the lower surface of the connecting sheet 3 are aligned with the corresponding positions of the upper surface of the first sheet 1 and the upper surface of the second sheet 2, respectively. Then, the connection and fixing operation is performed. The connecting sheet 3 is connected to the first sheet 1 and the second sheet 2 through the solder points 11 set around the upper surface of the connecting sheet 3. The connecting sheet 3 is then connected to the first sheet 1 and the second sheet 2 through the solder points 11, so that the connecting sheet 3 forms a stable connection with the first sheet 1 and the second sheet 2. At the same time, it is ensured that the two sides of the lower surface of the connecting sheet 3 are in contact with the corresponding positions of the upper surfaces of the first sheet 1 and the second sheet 2.

[0049] When entering the subsequent processing stage, the positioning hole 16 at the center of the upper surface of the connecting sheet 3 is used to coordinate the positioning mechanism of the new thermoformed product structure with the processing equipment to achieve precise positioning of the product during the processing, ensuring the smooth progress of subsequent thermoforming and other processing steps; during the process of the new thermoformed product structure being processed and put into use, if the product experiences thermal expansion and contraction due to changes in ambient temperature, the U-shaped thermal expansion compensation notches 14 on both sides of the center position of the upper surface of the connecting sheet 3 will absorb the stress generated by thermal expansion and contraction between the first sheet 1, the second sheet 2 and the connecting sheet 3 through their own deformation; then the positions of the first sheet 1 and the second sheet 2 are calibrated to ensure that they are on the preset assembly reference line;

[0050] Subsequently, at corresponding positions on the upper surfaces of the first sheet 1 and the second sheet 2, the fixing plate 4 is installed by bolt connection or welding. During the installation process, positioning tools are needed to ensure the levelness and positional accuracy of the fixing plate 4 to avoid displacement. After the fixing plate 4 is installed, the sawtooth block 5 is added to the inner side of the fixing plate 4 by welding or bonding. After the addition, the connection between the sawtooth block 5 and the fixing plate 4 must be checked to ensure that there is no looseness.

[0051] After the fixing plate 4 on the upper surface of the first sheet 1 and the second sheet 2 is installed, the opening position of the positioning groove 6 is determined according to the position of the fixing plate 4, ensuring that the positioning groove 6 is located on the front and back of the corresponding fixing plate 4. The iron positioning block 7 is placed into the inner cavity of the positioning groove 6, and the position of the iron positioning block 7 is adjusted so that it is completely in contact with the inner wall of the positioning groove 6. Finally, the iron positioning block 7 is fixed in the positioning groove 6 by bonding or interference fit.

[0052] Transport the connecting sheet 3 to the preset assembly position between the first sheet 1 and the second sheet 2, adjust the posture of the connecting sheet 3 so that the serrated grooves 10 on both sides of the connecting sheet 3 are aligned with the serrated blocks 5 on the inner side of the fixing plate 4 on the first sheet 1 and the second sheet 2 respectively, slowly push the connecting sheet 3 so that the serrated grooves 10 and the serrated blocks 5 gradually mesh until they are fully engaged, and finally check whether there are gaps or misalignments in the meshing parts to ensure tight meshing.

[0053] After the continuous material sheet 3 is processed, according to the positions of the iron positioning blocks 7 on the first material sheet 1 and the second material sheet 2, the permanent magnet block 9 is placed in the center of the inner cavity of the positioning seat 8. The posture of the permanent magnet block 9 is adjusted to ensure that its magnetic pole direction meets the magnetic attraction requirements. Finally, the permanent magnet block 9 is fixed in the inner cavity of the positioning seat 8 by bonding or snapping. When the serrated groove 10 of the continuous material sheet 3 engages with the serrated block 5, the up and down position of the continuous material sheet 3 is adjusted so that the permanent magnet block 9 in the positioning seat 8 is close to the corresponding iron positioning block 7. The magnetic attraction force between the permanent magnet block 9 and the iron positioning block 7 is used to further fix the continuous material sheet 3 in the preset position. Finally, the firmness of the magnetic connection is checked to ensure that there is no loosening.

[0054] After the heat conduction groove 12 is processed, the upper surface of the connecting material sheet 3 is marked to determine the installation positions of the honeycomb hollow array 13 and the heat insulation protrusion 15. The honeycomb hollow array 13 is located on both sides of the center front and rear ends of the upper surface of the connecting material sheet 3, and the heat insulation protrusion 15 is located on the center front and rear ends of the upper surface of the connecting material sheet 3. The hemispherical heat insulation protrusion 15 is installed at the corresponding marked position of the connecting material sheet 3 by bonding or welding. After installation, the processing and installation quality of the heat conduction groove 12, honeycomb hollow array 13 and heat insulation protrusion 15 are checked to ensure that there are no processing defects and installation deviations.
