Abstract
Description
Technical Field
[0001] This invention belongs to the field of carriage manufacturing technology and relates to an insulated panel for carriage layering. Background Technology
[0002] During cargo transportation, to efficiently utilize the space within the carriage, a layering device is typically installed to allow for the placement of goods in upper and lower layers. To achieve this layering function, metal rails are usually fixed to the side walls of the carriage, with their upper and lower ends extending to the top and bottom of the carriage's inner wall, respectively. For example, a layering device for a carriage disclosed in Chinese patent literature (application number: 202010021983.2) typically places the metal rails between two side panels, connecting them individually. This structure provides stable installation of the metal rails, ensuring their stability during layered transportation and thus ensuring high reliability of the layering function. However, this carriage structure lacks good thermal insulation performance, thus failing to meet the requirements of cold chain transportation.
[0003] Existing insulated truck body panels typically consist of an outer panel, an inner panel, and an insulation layer between them, with the insulation layer usually formed using a foaming process. For example, a high-performance insulated truck body panel disclosed in Chinese patent literature (application number: 202120331832.7) includes an integrally formed inner skin, an outer skin, edge sealing, and several reinforcing partitions. The reinforcing partitions divide the interior of the shell into multiple cavities, with the insulation core material evenly distributed within each cavity. While this insulated truck body panel has good thermal insulation performance, it lacks the function of compartment layering, thus limiting its application. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an insulated panel for compartment layering in train carriages. The technical problem to be solved by this invention is to resolve the issue that existing insulation panels cannot be used for compartment layering while ensuring high reliability of the compartment layering function, without affecting the insulation effect.
[0005] The objective of this invention can be achieved through the following technical solution: a thermal insulation panel for compartment layering in a vehicle, comprising a guide rail made of metal material and a panel made of non-metallic material, the panel comprising an outer side panel and an inner side panel arranged opposite to each other, characterized in that the inner side panel is provided with a vertically arranged strip groove, the guide rail is fixedly arranged in the strip groove, the top and bottom of the strip groove are respectively provided with heat insulation components made of non-metallic material, the heat insulation components are fixedly connected to the panel by fasteners, and the upper end of the guide rail is connected to the heat insulation component at the top of the strip groove and the lower end of the guide rail is connected to the heat insulation component at the bottom of the strip groove by a plug-in structure.
[0006] In this insulated compartment panel, the panel body is made of non-metallic materials, which reduces heat transfer between the inside and outside of the compartment. For the compartment's layering device, the structural strength and installation stability of the guide rails directly affect the reliability of the compartment's layering function. The guide rails are made of metallic materials, ensuring high structural strength. To facilitate the installation of the guide rails, this insulated compartment panel has strip-shaped grooves to fix them in place. These grooves provide positioning for the guide rails. Simultaneously, heat insulation components are installed at the top and bottom of the grooves, and these components are fixed to the panel body with fasteners. This ensures good installation stability for the heat insulation components. Furthermore, the top and bottom heat insulation components are inserted into the upper and lower ends of the guide rails, respectively, so that both the upper and lower ends of the guide rails are fixed by the heat insulation components. This further increases the stability of the guide rail installation, thereby ensuring high reliability of the compartment's layering function.
[0007] With guide rails installed on the insulated compartment panels, it becomes crucial to ensure that the rails, being made of metal, do not reduce the insulation effect of the compartment panels. Here, the insulation components serve a dual purpose: they not only fix the guide rails as mentioned above, but also, because they are made of non-metallic materials, the top and bottom insulation components also act as heat insulators, preventing heat transfer between the guide rails and the top and bottom panels of the compartment, thus ensuring good insulation performance of the insulated compartment panels.
[0008] In the aforementioned insulated compartment panel for compartment layering, the plug-in structure includes plug-in connectors mounted on the insulation components. The guide rail has through holes extending from both ends along its length. The plug-in connector of the insulation component located at the top of the strip-shaped groove is inserted downwards into the upper opening of the through hole, while the plug-in connector of the insulation component located at the bottom of the strip-shaped groove is inserted upwards into the lower opening of the through hole. The plug-in connectors of the insulation components are inserted into the through holes, achieving a plug-in fixation between the guide rail and the insulation component, thus improving the stability of the guide rail installation. The guide rail is made of metal, and by forming through holes at both ends inside, this design not only meets the requirements for plug-in connection between the guide rail and the insulation component but also reduces the weight of the guide rail, making it lighter and thus facilitating stable fixation of the guide rail to the panel, ensuring the reliability of the compartment layering function.
[0009] In the aforementioned insulated compartment panel for compartment layering, the insertion structure includes an extension on the heat insulation component. An upper insertion groove is formed between the extension of the heat insulation component at the top of the strip-shaped groove and the bottom of the groove. A lower insertion groove is formed between the extension of the heat insulation component at the bottom of the strip-shaped groove and the bottom of the groove. The upper end of the guide rail is inserted into the upper insertion groove, and the lower end of the guide rail is inserted into the lower insertion groove. This design ensures that the upper and lower ends of the guide rail are fixed by pressure from the upper extension of the heat insulation component, improving the stability of the guide rail installation. Furthermore, since this structure eliminates the need for through holes at both ends to be formed on the guide rail, it facilitates the manufacturing of the guide rail.
[0010] In the aforementioned insulated compartment panel for compartment layering, the panel further includes an intermediate layer panel disposed between the outer and inner side panels. The outer and inner side panels are spaced apart from the intermediate layer panel. Two connecting blocks made of non-metallic material are also provided between the outer and intermediate layer panels. These two connecting blocks are respectively positioned opposite the aforementioned heat insulation components. Fasteners pass through the heat insulation components and the intermediate layer panel sequentially and then connect to the oppositely positioned connecting blocks. By setting the connecting blocks, the fasteners pass through the heat insulation components and the intermediate layer panel before connecting to the connecting blocks, increasing the installation stability of the heat insulation components, improving the stability of the guide rails, and thus enhancing the reliability of the compartment layering function. The connecting blocks are made of non-metallic material, which prevents heat transfer between the connecting blocks and the outside environment, thereby ensuring good heat insulation performance of the insulated compartment panel. The addition of the intermediate layer panel creates a three-layer structure, and the connecting blocks, positioned between the outer and intermediate layer panels, facilitate the installation of the connecting blocks and ensure their stability. Simultaneously, the intermediate layer panel also improves the panel's resistance to deformation, preventing deformation during use.
[0011] In the aforementioned insulated compartment panel for compartment layering, the outer side panel, middle layer panel, and inner and outer side panels are parallel to each other. The bottom of the groove in the strip-shaped recess is coplanar with the side of the middle layer panel facing away from the outer side panel. The back of the guide rail rests against the bottom of the groove in the strip-shaped recess and is glued to the groove. This design ensures that when the guide rail is placed in the groove, the middle layer panel provides support, improving the stability and load-bearing capacity of the guide rail, thereby enhancing the reliability of the compartment layering function. Gluing the guide rail to the groove offers advantages such as ease of manufacturing and low cost. Furthermore, the combined effect of the insulation component on fixing the guide rail provides stable installation.
[0012] In the aforementioned insulated panel for compartment layering, the through-hole has a rectangular cross-section, and the connector is rectangular in shape. This structure provides an anti-rotation positioning effect for the guide rail when the connector is inserted into the through-hole, and the larger mating area between the connector and the insertion hole further enhances the stability of the guide rail installation.
[0013] In the aforementioned insulated panel for compartment layering, the panel is a one-piece structure manufactured using a continuous pultrusion molding process. The panel material is fiberglass or glass fiber, while the insulation components and connecting blocks are made of plastic, rubber, or wood. The continuous pultrusion molding process not only facilitates panel manufacturing and reduces manufacturing costs but also produces a one-piece structure with high structural strength. Fiberglass or glass fiber panels offer insulation and heat insulation properties, along with advantages such as light weight and high structural strength. The insulation components and connecting blocks can be made of the same or different materials. The insulation components are preferably made of plastic, allowing for higher precision in their insertion into the guide rails and improving the accuracy of the fit. The connecting blocks are preferably made of wood, ensuring stable guide rail installation and reducing costs.
[0014] In the aforementioned insulated compartment panel for compartment layering, the panel further includes two opposing side sealing plates. The outer and inner side panels are connected on the same side by one of these side sealing plates. A plurality of first partitions connect the outer side panel and the intermediate layer panel. These first partitions are arranged sequentially at intervals along the length of the top edge of the intermediate layer panel. Each side sealing plate forms an installation cavity with its adjacent first partition and with each pair of adjacent first partitions. Insulation components are installed within these installation cavities. By installing insulation components within the installation cavities, the insulated compartment panel achieves high thermal insulation performance. Furthermore, since the insulation components are located between the outer side panel and the intermediate partition, they also prevent heat transfer between the guide rails and the outside environment, thus ensuring good insulation performance of the insulated compartment panel. When goods are placed inside the compartment, they will inevitably collide with the insulated compartment panels. However, since the insulation components are located between the outer panel and the middle partition, and there is a gap between the middle partition and the inner panel, even if the inner panel is dented due to impact, it will not cause deformation or damage to the insulation components. This results in good insulation performance and a long service life for the insulated compartment panels.
[0015] In the aforementioned insulated compartment panel for compartment layering, several second partitions connect the inner side panel and the middle layer panel, and these second partitions are arranged sequentially at intervals along the length of the top edge of the middle layer panel. During the transportation and loading / unloading of goods inside the compartment, the side walls of the compartment will inevitably be impacted. At this time, the second partitions provide structural reinforcement, further improving the deformation resistance of the panel and preventing deformation of the insulation components caused by impact. This protects the insulation components, resulting in good insulation performance and a long service life for the insulated compartment panel. In addition, the second partitions divide the space between the middle layer panel and the inner side panel into several spare cavities. These spare cavities can be used for additional functions, such as placing insulation components inside to improve insulation performance, or placing discharge plates to create an electric field inside the compartment to achieve refrigeration.
[0016] In the aforementioned insulated panel for compartment layering, one side panel has two parallel interlocking protrusions on its outer surface, and the other side panel has an interlocking groove on its outer surface for engaging with the interlocking protrusions when the two panels are joined together. The groove is adjacent to one side edge of the inner side panel. The sidewalls of the compartment are formed by splicing several panels. The design of the interlocking protrusions and grooves allows for rapid assembly of the panels, facilitating compartment manufacturing. When multiple panels are joined to form the sidewalls, the weakest area of the compartment structure is the joint between adjacent panels. A metal guide rail is installed within the groove, and since the groove is adjacent to one side edge of the inner side panel, the guide rail is close to the joint between adjacent panels. Therefore, the guide rail supports the joint, resists impact from cargo, prevents deformation and damage to the joint, and extends the service life of the compartment.
[0017] In the aforementioned insulated compartment panels for compartment layering, the insulation component is a polyurethane foam layer formed by foaming within the installation cavity; or the insulation component is inserted into the installation cavity, and is made by placing a heat-insulating core board inside a barrier bag and vacuum-sealing the barrier bag. The polyurethane foam layer has good insulation effect, effectively isolating heat exchange between the inside and outside of the compartment, thus improving the refrigeration effect of the compartment. Preferably, the insulation component is made by placing a heat-insulating core board inside a barrier bag and vacuum-sealing the barrier bag. The vacuuming process during manufacturing results in high density and thus more efficient insulation performance.
[0018] Compared with existing technologies, the insulated panels used for compartment layering have the following advantages:
[0019] 1. This insulated compartment panel is equipped with strip grooves to fix the guide rails. At the same time, heat insulation components are also provided at the top and bottom of the strip grooves. The heat insulation components at the top and bottom are respectively inserted into the upper and lower ends of the guide rails, so that the upper and lower ends of the guide rails are fixed by the heat insulation components. This further increases the stability of the guide rail installation and ensures that the compartment layering function has high reliability.
[0020] 2. The insulation components of this insulated box panel are made of non-metallic materials, which can isolate the heat transfer between the guide rail and the top and bottom panels of the box, thus ensuring the good insulation effect of the insulated box panel.
[0021] 3. The insulation components of this insulated panel are inserted into the installation cavity, thus making the panel easy to manufacture. The insulation components are made by placing an insulating core board inside a barrier bag and then vacuum-sealing the barrier bag. The vacuum process during manufacturing results in high density and thus more efficient insulation performance, giving the insulated panel excellent thermal insulation properties.

Detailed Implementation
[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0036] Example 1
[0037] like Figure 1 and Figure 2As shown, the insulated panel used for compartment layering includes guide rails 1 made of metal and panel 2 made of non-metallic materials. Panel 2 is a one-piece structure manufactured using a continuous pultrusion molding process, and the material of panel 2 is fiberglass or glass fiber. Combined with... Figure 7 As shown, the plate body 2 includes an outer side plate 21, an inner side plate 22 and an intermediate layer plate 24 disposed between the outer side plate 21 and the inner side plate 22. The outer side plate 21 and the inner side plate 22 are parallel to and spaced apart from the intermediate layer plate 24. The inner side plate 22 is provided with a vertically arranged strip groove 23. The guide rail 1 is fixedly disposed in the strip groove 23. The top and bottom of the strip groove 23 are respectively provided with heat insulation components 3 made of non-metallic material. The heat insulation components 3 are fixedly connected to the plate body 2 by fasteners 5. The upper end of the guide rail 1 is connected to the heat insulation component 3 at the top of the strip groove 23 and the lower end of the guide rail 1 is connected to the heat insulation component 3 at the bottom of the strip groove 23 by a plug-in structure.
[0038] Furthermore, such as Figure 3 and Figure 4 As shown, the plate body 2 also includes two opposing side sealing plates 25. The outer side plate 21 and the inner side plate 22 are connected on the same side by one of the aforementioned side sealing plates 25. A plurality of first partitions 26 are connected between the outer side plate 21 and the middle layer plate 24. The plurality of first partitions 26 are arranged sequentially at intervals along the length direction of the top edge of the middle layer plate 24. Each side sealing plate 25 and the adjacent first partition 26, as well as between each pair of adjacent first partitions 26, form an installation cavity 27. An insulation component 6 is inserted into the installation cavity 27. The insulation component 6 is made by placing the heat insulation core plate in the barrier bag and vacuum sealing the barrier bag. The insulation component 6 is vacuum sealed during manufacturing, so it has a high tightness and thus achieves more efficient heat insulation performance.
[0039] like Figure 2 As shown, a plurality of second partitions 28 are connected between the inner side panel 22 and the middle layer panel 24. The plurality of second partitions 28 are arranged sequentially at intervals along the length of the top edge of the middle layer panel 24. The arrangement of the second partitions 28 divides the space between the middle layer panel 24 and the inner side panel 22 into a plurality of spare cavities. The spare cavities serve as backups and can be used for additional functions, such as placing insulation components 6 in the spare cavities to improve insulation performance; or placing discharge plates to form an electric field in the interior space to achieve the interior refrigeration function, etc.
[0040] like Figure 5 and Figure 10As shown, two connecting blocks 4 made of non-metallic material are provided between the outer panel 21 and the middle layer panel 24. The two connecting blocks 4 are respectively positioned opposite to the aforementioned heat insulation component 3. Fasteners 5 pass through the heat insulation component 3 and the middle layer panel 24 in sequence and are then connected to the oppositely positioned connecting blocks 4. By setting the connecting blocks 4 and connecting the fasteners 5 through the heat insulation component 3 and the middle layer panel 24, the installation stability of the heat insulation component 3 is increased, thereby improving the stability of the guide rail 1 and enhancing the reliability of the compartment layering function. The heat insulation component 3 and the connecting blocks 4 are made of plastic, rubber, or wood. The materials of the heat insulation component 3 and the connecting blocks 4 can be the same or different. Preferably, the heat insulation component 3 is made of plastic, allowing for higher precision in its insertion into the guide rail 1 and improving the accuracy of the insertion fit. The connecting blocks 4 are made of wood, ensuring not only the stability of the guide rail 1 installation but also reducing costs.
[0041] Combination Figure 6 , Figure 8 and Figure 9 As shown, the bottom of the groove 23 is coplanar with the side of the intermediate layer 24 facing away from the outer side plate 21. The back of the guide rail 1 rests against the bottom of the groove 23, and the guide rail 1 is glued to the groove 23. The guide rail 1 has through holes 1a extending through both ends along its length. Each heat insulation component 3 has a connector 31. The connector 31 of the heat insulation component 3 located at the top of the groove 23 is inserted downward into the upper opening of the through hole 1a, and the connector 31 of the heat insulation component 3 located at the bottom of the groove 23 is inserted upward into the lower opening of the through hole 1a. The connector 31 of the heat insulation component 3 is inserted into the through hole 1a, realizing the insertion and fixation of the guide rail 1 and the heat insulation component 3, improving the stability of the guide rail 1 installation. The cross-section of the through hole 1a is rectangular, and the connector 31 is rectangular block-shaped. This structure enables the connector 31 to have an anti-rotation positioning effect on the guide rail 1 when it is inserted into the through hole 1a of the guide rail 1. Moreover, the mating area between the connector 31 and the insertion hole is large, which can further improve the stability of the guide rail 1 installation.
[0042] like Figure 7 and Figure 11As shown, in this insulated compartment panel, one side panel 25 has two parallel interlocking protrusions 251 on its outer surface, and the other side panel 25 has an interlocking groove 252 on its outer surface for interlocking with the protrusions 251 when the two panels 2 are spliced together. A strip-shaped groove 23 is adjacent to one side edge of the inner side panel 22. This design allows the side walls of the compartment to be formed by splicing several panels 2, facilitating compartment manufacturing. When multiple panels 2 are spliced to form the side walls of the compartment, the weakest area of the compartment structure is the splicing point between adjacent panels 2. A guide rail 1 made of metal is provided within the strip-shaped groove 23, and since the strip-shaped groove 23 is adjacent to one side edge of the inner side panel 22, the guide rail 1 is close to the splicing point between adjacent panels 2. Therefore, the guide rail 1 can support the splicing point, resisting cargo impact, preventing deformation and damage to the splicing point, and extending the service life of the compartment.
[0043] Example 2
[0044] This embodiment is basically the same as embodiment one in structure and principle, except that: Figure 12 As shown, the insertion structure includes an extension 32 on the heat insulation member 3. An upper insertion groove is formed between the extension 32 of the heat insulation member 3 at the top of the strip groove 23 and the bottom of the strip groove 23. A lower insertion groove is formed between the extension 32 of the heat insulation member 3 at the bottom of the strip groove 23 and the bottom of the strip groove 23. The upper end of the guide rail 1 is inserted into the upper insertion groove, and the lower end of the guide rail 1 is inserted into the lower insertion groove. Through this design, the upper and lower ends of the guide rail 1 are respectively fixed by the pressure of the upper extension 32 of the heat insulation member 3, which improves the stability of the guide rail 1 installation. At the same time, since this structure does not require forming through holes 1a at both ends on the guide rail 1, it makes the manufacturing of the guide rail 1 more convenient.
[0045] Example 3
[0046] This embodiment is basically the same as the first embodiment in terms of structure and principle. The difference is that the insertion structure has an insertion part at the upper end and the lower end of the guide rail 1, and an insertion hole on the heat insulation component 3. The insertion part at the upper end of the guide rail 1 is inserted into the insertion hole of the top heat insulation component 3. Similarly, the insertion part at the lower end of the guide rail 1 is inserted into the insertion hole of the bottom heat insulation component 3.
[0047] Example 4
[0048] This embodiment is basically the same as Embodiment 1 in structure and principle, except that the insulation component 6 is a polyurethane foam layer formed within the installation cavity 27. The polyurethane foam layer has good insulation effect, effectively isolating heat exchange between the inside and outside of the compartment and improving the refrigeration effect of the compartment.
