Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle body structure and a vehicle. Background Technology

[0002] Vehicles such as light passenger buses or light trucks generally include a cargo box structure. To improve the thermal insulation performance of the cargo box structure, it includes the main body and an insulated inner compartment. The insulated inner compartment is located on the inner wall of the main body. In related technologies, the insulated inner compartment includes panels such as the front panel, top panel, bottom panel, left panel, and right panel. Due to the large dimensions and volume of the panels, interference can easily occur between the panels and the main body during installation, requiring manual adjustment, which is time-consuming, labor-intensive, and inconvenient. Furthermore, the panels of the insulated inner compartment have poor versatility; different vehicle models require separate molds for different panels of the insulated inner compartment, resulting in high costs. Utility Model Content

[0003] In view of this, this application provides a car body structure and vehicle, by setting at least one of the front panel, top panel, bottom panel, left panel and right panel as a splicing structure. Since the splicing structure is formed by splicing multiple independently processed splicing panels together without being detachably fixed together, the splicing panels can be installed separately in the car body, and the multiple splicing panels are ultimately fixed together without being detachably fixed to form the splicing structure. Since the splicing panels are small in size, it is beneficial to improve the installation convenience and versatility of the insulated inner car body panels to at least a certain extent.

[0004] Firstly, according to the vehicle body structure of this application, it includes: a vehicle body and an insulated inner compartment. The vehicle body includes a vehicle body with a receiving space. The insulated inner compartment is located within the receiving space and includes a front panel, a top panel, a bottom panel, a left panel, and a right panel. The front panel is fixed to the front wall inside the vehicle body, the top panel is fixed to the top wall inside the vehicle body, the bottom panel is fixed to the bottom wall inside the vehicle body, the left panel is fixed to the left wall inside the vehicle body, and the right panel is fixed to the right wall inside the vehicle body; at least one of the front panel, the top panel, the bottom panel, the left panel, and the right panel is a spliced ​​structure, which is formed by splicing multiple splicing panels together and fixing them together in a non-detachable manner.

[0005] According to the vehicle body structure of this application, by setting at least one of the front panel, roof panel, floor panel, left panel, and right panel as a splicing structure, since the splicing structure is spliced ​​from multiple splicing panels, and the splicing panels are much smaller in size than the splicing structure itself (taking the left panel as an example, the splicing panel used to splice the left panel is relatively small in size compared to the left panel itself), during the assembly process of the vehicle body structure, splicing panels can be installed individually within the accommodating space, and multiple splicing panels can be spliced ​​to form the corresponding splicing structure. This is more convenient than in related technologies where a complete, one-piece panel (e.g., the left panel) is installed on the inner wall of the accommodating space.

[0006] Furthermore, since the splicing structure is composed of multiple splicing panels, it is advantageous to splice different numbers of splicing panels according to the different vehicle body structures, so that the splicing structure can be spliced ​​into different sizes, making the splicing structure applicable to the body structures of different vehicle models, thereby improving the versatility of the insulated inner body panels to at least a certain extent.

[0007] Furthermore, in splicing structures, fixing any two adjacent splicing panels together in an unremovable manner can help improve the structural stability and strength of the splicing structure.

The top left flange is located at the left end of the top plate body and folds downward, and the top right flange is located at the right end of the top plate body and folds downward; and / or, the bottom plate includes a bottom plate body, a bottom left flange, and a bottom right flange. The bottom left flange is located at the left end of the bottom plate body and folds upward, and the bottom right flange is located at the right end of the bottom plate body and folds upward.

[0015] In one possible implementation of the first aspect of this application, any two adjacent panels of the front panel, the top panel, the bottom panel, the left panel, and the right panel have stepped portions formed at their adjacent ends, and the stepped portions of any two adjacent panels are adapted to each other.

[0016] In one possible implementation of the first aspect of this application, the stepped portions of any two adjacent panels are fixedly connected by structural adhesive.

[0017] In one possible implementation of the first aspect of this application, the top plate, the left side panel, and the right side panel are all spliced ​​structures, while the bottom plate and the front side panel are all integral structures.

[0040] In related technologies, to improve the thermal insulation performance of the vehicle body structure, the vehicle body structure includes a main body and an insulated inner compartment. The insulated inner compartment is located on the inner wall of the main body. The insulated inner compartment includes panels such as a front panel, top panel, bottom panel, left panel, and right panel. The panels are bonded to the main body using structural adhesive and fixed with rivets. Due to the large dimensions and volume of the panels, interference can easily occur between the panels and the main body during installation, requiring manual adjustment, which is time-consuming, labor-intensive, and inconvenient. Furthermore, the panels of the insulated inner compartment have poor versatility; different vehicle models require separate molds for different panels, resulting in high costs.

[0041] Based on this, this application provides a vehicle with a carriage structure, and the structure of the vehicle of this application will be described in detail below with reference to the accompanying drawings.

[0042] This application provides a vehicle with a cargo box structure. The vehicle includes, but is not limited to, light passenger vehicles or light trucks. Specifically, the vehicle 100 can be a refrigerated vehicle, such as a refrigerated light passenger vehicle.

[0043] Please see Figure 1 According to embodiments of this application, the vehicle 100 may include a driver's cab 20 and a cargo box structure 10.

[0044] The carriage structure 10 is located behind the driver's cab 20.

[0046] Please see Figure 2 and Figure 3 The carriage structure 10 includes: carriage 1 and insulated inner carriage 2.

[0047] The carriage 1 includes the carriage body 11 and the rear tail door 12.

[0048] The carriage body 11 has a receiving space 111. The receiving space 111 has an opening (not shown) at the rear. The rear tailgate 12 is connected to the carriage body 11 to open or close the opening, thereby facilitating the loading and unloading of items. For example, the rear tailgate 12 is rotatably connected to the carriage body 11 to open or close the opening.

[0049] The rear tailgate 12 can be one or more. For example, as shown... Figure 2 As shown, there are two rear tailgates 12, which are distributed on the left and right sides.

[0050] The insulated inner compartment 2 is located within the accommodating space 111 and is fixed to the inner wall of the accommodating space 111.

[0051] Please see Figure 3 , Figure 4 and Figure 5 The insulated inner compartment 2 includes a front panel 21, a top panel 22, a bottom panel 23, a left panel 24, and a right panel 25.

[0052] The front panel 21 is fixed to the front wall surface inside the vehicle body 11, that is, the front wall surface of the accommodating space 111. The connection between the front panel 21 and the front wall surface can be adhesive bonding, which is more aesthetically pleasing than riveting. In other embodiments, the two can also be riveted.

[0053] The top panel 22, left side panel 24, bottom panel 23, and right side panel 25 are sequentially distributed and connected in the circumferential direction of the front side panel 21. The connection between any two adjacent panels can be adhesive bonding, which is more aesthetically pleasing than riveting. In other embodiments, any two adjacent panels can also be riveted.

[0054] The top plate 22 is fixed to the top wall surface inside the carriage body 11, that is, to the top wall surface 1113 of the accommodating space 111. The connection between the top plate 22 and the top wall surface 1113 can be adhesive, which is more aesthetically pleasing than riveting. In other embodiments, the two can also be riveted.

[0055] The top plate 22 is connected to the top of the front panel 21. The connection between the top plate 22 and the top of the front panel 21 can be by bonding, which is more aesthetically pleasing than riveting. In other embodiments, riveting can also be used between the two.

[0056] The base plate 23 is fixed to the bottom wall surface inside the carriage body 11, that is, to the bottom wall surface 1114 of the accommodating space 111. The connection between the base plate 23 and the bottom wall surface 1114 can be adhesive bonding, which is more aesthetically pleasing than riveting. In other embodiments, the two can also be riveted.

[0057] The bottom plate 23 is connected to the bottom end of the front panel 21. The connection between the bottom plate 23 and the bottom end of the front panel 21 can be by bonding, which is more aesthetically pleasing than riveting. In other embodiments, the two can also be connected by riveting.

[0058] The left side panel 24 is fixed to the left wall of the carriage body 11, that is, to the left wall 1111 of the accommodating space 111. The connection between the left side panel 24 and the left wall 1111 can be adhesive, which is more aesthetically pleasing than riveting. In other embodiments, the two can also be riveted.

[0059] The left side panel 24 is connected to the left end of the front side panel 21. The connection between the left side panel 24 and the left end of the front side panel 21 can be achieved by bonding, which is more aesthetically pleasing than riveting. In other embodiments, riveting can also be used between the two.

[0060] The right side panel 25 is fixed to the right wall of the carriage body 11, that is, to the right wall 1112 of the accommodating space 111. The connection between the right side panel 25 and the right wall 1112 can be adhesive bonding, which is more aesthetically pleasing than riveting. In other embodiments, the two can also be riveted.

[0061] The right side panel 25 is connected to the right end of the front side panel 21. The connection between the right side panel 25 and the right end of the front side panel 21 can be achieved by bonding, which is more aesthetically pleasing than riveting. In other embodiments, riveting can also be used between the two.

[0062] At least one of the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 is a splicing structure P. That is, one of the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 is a splicing structure P; or two of the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 are splicing structures P; or three of the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 are splicing structures P; or four of the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 are splicing structures P; or all of the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 are splicing structures P.

[0063] For example, the front panel 21 can be a spliced ​​structure P, while the other panels are integral structures; the top panel 22 can be a spliced ​​structure P, while the other panels are integral structures; the bottom panel 23 can be a spliced ​​structure P, while the other panels are integral structures; the left panel 24 can be a spliced ​​structure P, while the other panels are integral structures; or the right panel 25 can be a spliced ​​structure P, while the other panels are integral structures.

[0064] For example, the front panel 21 and the top panel 22 may both be spliced ​​structures P, while the other panels are integral structures; the top panel 22 and the bottom panel 23 may both be spliced ​​structures P, while the other panels are integral structures; the top panel 22 and the left panel 24 may both be spliced ​​structures P, while the other panels are integral structures; the top panel 22 and the right panel 25 may both be spliced ​​structures P, while the other panels are integral structures.

[0065] For example, the top panel 22, left side panel 24, and right side panel 25 can be a spliced ​​structure P, while the front side panel 21 and bottom panel 23 can be an integral structure; the top panel 22, bottom panel 23, and left side panel 24 can be a spliced ​​structure P, while the front side panel 21 and right side panel 25 can be an integral structure; the bottom panel 23, left side panel 24, and right side panel 25 can be a spliced ​​structure P, while the top panel 22 and front side panel 21 can be an integral structure.

[0066] For example, the top panel 22, bottom panel 23, left side panel 24, and right side panel 25 can all be spliced ​​structures P, while the front side panel 21 is a one-piece structure.

[0067] Specifically, in Figure 3 and Figure 4In the specific example shown, the top panel 22, left side panel 24, and right side panel 25 are spliced ​​structures P, while the front side panel 21 and bottom panel 23 are integral structures. This integral bottom panel 23 has high structural strength, improving its load-bearing capacity for the top panel 22, left side panel 24, right side panel 25, front side panel 21, and the items or personnel inside the insulated inner compartment 2.

[0068] It should be noted that "integrated structure" means that the panel is not made by splicing, welding or fixing several panels together in other ways, but rather that the panel is a single structural unit.

[0069] Please continue reading. Figure 4 , Figure 5 and Figure 6 Each splicing structure P is formed by splicing multiple splicing plates P1 together and fixing them together in a non-detachable manner. That is to say, multiple splicing plates P1 are first processed separately, and each splicing structure P is formed by splicing multiple splicing plates P1 together and then fixing them together. This fixing method makes it impossible to disassemble any two adjacent splicing plates P1.

[0070] It should be noted that in the splicing structure P, the splicing direction of the multiple splicing panels P1 is perpendicular to the thickness direction of the splicing structure P.

[0071] Since the splicing structure P is composed of multiple splicing panels P1, and each splicing panel P1 is much smaller than the splicing structure P itself, taking the left side panel 24 as an example, the splicing panel P1 used to splice the left side panel 24 is relatively small compared to the left side panel 24 itself. Therefore, during the assembly process of the carriage structure 10, the splicing panels P1 can be installed individually within the accommodating space 111, and multiple splicing panels P1 can be spliced ​​together to form the corresponding splicing structure P. This is more convenient than the related technology of installing a complete one-piece panel (e.g., the left side panel 24) on the inner wall of the accommodating space 111.

[0072] Furthermore, since the splicing structure P is spliced ​​from multiple splicing panels P1, it is advantageous to splice different numbers of splicing panels P1 according to the different vehicle body structures 10, so that the splicing structure P can be spliced ​​into different sizes, making the splicing structure P applicable to the vehicle body structures 10 of different vehicle models, thereby helping to improve the versatility of the insulated inner compartment 2 panels to at least a certain extent.

[0073] Furthermore, in the splicing structure P, the fact that any two adjacent splicing plates P1 are fixed together in an unremovable manner can help improve the structural stability and structural strength of the splicing structure P.

[0074] Here, it needs to be explained that the "multiple splicing panels P1" in the splicing structure P are processed independently, that is, the multiple splicing panels P1 are processed separately, meaning that the multiple splicing panels P1 are processed separately.

[0075] Here, it's also necessary to clarify that "multiple" refers to two or more. Figure 3 and Figure 4 In the specific example shown, the top panel 22, the left side panel 24, and the right side panel 25 are all formed by splicing two splicing plates P1. In other embodiments, the top panel 22, the left side panel 24, and the right side panel 25 are all formed by splicing three, four, or five splicing plates P1.

[0076] For example, when at least one of the top plate, bottom plate, left side panel, and right side panel is a splicing structure P, the aforementioned splicing plates P1 of the splicing structure P can be spliced ​​together in the front-to-back direction. In this way, the splicing structure P can be spliced ​​into different sizes in the front-to-back direction, which is beneficial for the splicing structure P of the insulated inner compartment 2 to be applicable to the compartment structure 10 of vehicle models with different wheelbases, and helps to improve the versatility of the panels of the insulated inner compartment 2 to at least a certain extent.

[0077] In some embodiments of this application, please refer to Figure 7 In the splicing structure P, any two adjacent splicing plates P1 have concave and convex structures P11 formed on their surfaces facing each other. The concave and convex structures P11 of any two adjacent splicing plates P1 are compatible. This has two advantages: firstly, the fit of the concave and convex structures P11 between two adjacent splicing plates P1 helps to fix and position them, improving the reliability of the fit and the structural stability of the splicing structure P; secondly, because the concave and convex structures P11 are uneven, it increases the mating area between two adjacent splicing plates P1, resulting in a tighter fit and improving the insulation effect of the inner insulation compartment 2.

[0078] For example, please refer to Figure 7 The concave-convex structure P11 is formed in a stepped shape. This results in a simple structure, facilitating manufacturing. Furthermore, the mating surfaces of the concave-convex structures P11 of two adjacent splicing plates P1 are approximately "Z"-shaped, which helps to increase the mating area between the two adjacent splicing plates P1. This leads to a tighter fit between the concave-convex structures P11 of the two adjacent splicing plates P1, resulting in better insulation. Of course, this application is not limited to this; in other embodiments, the concave-convex structure P11 can also be formed in other shapes.

[0079] In some embodiments of this application, the arrangement direction of two adjacent splicing plates P1 is a first direction, the thickness direction of the splicing plate P1 is a second direction, and the concave-convex structure P11 extends along a third direction to both ends of the splicing plate P1 where the concave-convex structure P11 is located. The first direction, the second direction, and the third direction are perpendicular to each other. In this way, it is beneficial for two adjacent splicing plates P1 to fully cooperate through the concave-convex structure P11 in the third direction. On the one hand, it is beneficial to use the cooperation of the concave-convex structure P11 of two adjacent splicing plates P1 to fix the two adjacent splicing plates P1, thereby improving the reliability of the cooperation between the two adjacent splicing plates P1 and the structural stability of the splicing structure P. On the other hand, since the concave-convex structure P11 is uneven, it is beneficial to increase the cooperation area between the two adjacent splicing plates P1, making the cooperation between the concave-convex structure P11 of the two adjacent splicing plates P1 more tight and improving the heat preservation effect.

[0080] It should be noted that in the splicing structure P, the thickness direction of the splicing plate P1 is the thickness direction of the splicing structure P, and it is unique. The first direction is referenced to the arrangement direction of any two adjacent splicing plates P1. In the splicing structure P, the first direction and the third direction may not be unique.

[0081] In some embodiments of this application, in the splicing structure P, the concave and convex structures P11 of any two adjacent splicing plates P1 are fixedly connected by structural adhesive. This achieves two advantages: firstly, the two splicing plates P1 are non-removable, improving the structural strength and stability of the splicing structure P; secondly, the structural adhesive improves the sealing between adjacent splicing plates P1, thereby enhancing the thermal insulation capacity of the carriage structure 10; and thirdly, compared to riveting, structural adhesive bonding avoids exposed structural adhesive and is more aesthetically pleasing.

[0082] In related technologies, the insulated inner compartment 2 has a sandwich structure, meaning a foam layer is sandwiched between two supporting panels. This results in straight panels of uniform thickness for the insulated inner compartment 2. However, for the vehicle body structure 10 of the vehicle 100, to ensure the structural strength of the body 11, the inner wall of the accommodating space 111 is often not flat. Consequently, when the sandwich structure panels in the related technologies are fixed to the inner wall of the accommodating space 111, their surfaces facing each other cannot fit together, resulting in gaps. This leads to a reduction in the volume of the vehicle body structure 10 with the insulated inner compartment 2, thus decreasing space utilization.

[0083] In some embodiments of this application, the surface of the front panel 21 facing the front wall has a similar shape to the front wall. This improves the fit between the front panel 21 and the front wall, avoiding gaps and increasing the volume and space utilization of the vehicle body structure 10.

[0084] Furthermore, when the front wall surface inside the carriage body 11 is uneven, since the surface of the front panel 21 facing the front wall surface is similar in shape to the front wall surface, the concave part of the front panel 21 corresponds to the convex part of the front wall surface, and the convex part of the front panel 21 corresponds to the concave part of the front wall surface. This is beneficial to use the similarity between the surface of the front panel 21 facing the front wall surface and the front wall surface to play a positioning role between the two, thereby improving assembly efficiency.

[0085] In some embodiments of this application, the surface of the left side panel 24 facing the left wall 1111 has a similar shape to the left wall 1111. In this way, when the left side panel 24 and the left wall 1111 are fitted together, the fit between them is higher, avoiding the problem of gaps between them, which is conducive to increasing the volume of the carriage structure 10 and improving the space utilization of the carriage structure 10.

[0086] Furthermore, when the left wall surface 1111 inside the carriage body 11 is uneven, since the surface of the left panel 24 facing the left wall surface 1111 is similar in shape to the left wall surface 1111, the concave part of the left panel 24 corresponds to the convex part of the left wall surface 1111, and the convex part of the left panel 24 corresponds to the concave part of the left wall surface 1111. This is beneficial to use the similarity between the surface of the left panel 24 facing the left wall surface 1111 and the left wall surface 1111 to play a positioning role between the two, thereby improving assembly efficiency.

[0087] In some embodiments of this application, the surface of the right side panel 25 facing the right wall 1112 has a similar shape to the right wall 1112. This results in a higher degree of compatibility between the right side panel 25 and the right wall 1112 when they mate, avoiding gaps between them and improving the volume and space utilization of the carriage structure 10.

[0088] Furthermore, when the right wall surface 1112 inside the carriage body 11 is uneven, since the surface of the right panel 25 facing the right wall surface 1112 is similar in shape to the right wall surface 1112, the concave part of the right panel 25 corresponds to the convex part of the right wall surface 1112, and the convex part of the right panel 25 corresponds to the concave part of the right wall surface 1112. This is beneficial to use the similarity between the surface of the right panel 25 facing the right wall surface 1112 and the right wall surface 1112 to position the fit between the two, thereby improving assembly efficiency.

[0089] In some embodiments of this application, the surface of the top plate 22 facing the top wall 1113 has a similar shape to the top wall 1113. In this way, when the top plate 22 and the top wall 1113 are fitted together, the compatibility between them is higher, avoiding the problem of gaps between them, which is conducive to increasing the volume of the carriage structure 10 and improving the space utilization of the carriage structure 10.

[0090] Furthermore, when the top wall surface 1113 inside the carriage body 11 is uneven, since the surface of the top plate 22 facing the top wall surface 1113 is similar in shape to the top wall surface 1113, the concave part of the top plate 22 corresponds to the convex part of the top wall surface 1113, and the convex part of the top plate 22 corresponds to the concave part of the top wall surface 1113. This is beneficial to use the similarity between the surface of the top plate 22 facing the top wall surface 1113 and the top wall surface 1113 to play a positioning role between the two, thereby improving assembly efficiency.

[0091] In some embodiments of this application, the surface of the base plate 23 facing the bottom wall surface 1114 has a similar shape to the bottom wall surface 1114. In this way, when the base plate 23 and the bottom wall surface 1114 are fitted together, the compatibility between them is higher, avoiding the problem of gaps between them, which is conducive to increasing the volume of the carriage structure 10 and improving the space utilization of the carriage structure 10.

[0092] Furthermore, when the bottom wall surface 1114 inside the carriage body 11 is uneven, since the surface of the bottom plate 23 facing the bottom wall surface 1114 is similar in shape to the bottom wall surface 1114, the concave part of the bottom plate 23 corresponds to the convex part of the bottom wall surface 1114, and the convex part of the bottom plate 23 corresponds to the concave part of the bottom wall surface 1114. This is beneficial to use the similarity between the surface of the bottom plate 23 facing the bottom wall surface 1114 and the bottom wall surface 1114 to play a positioning role between the two, thereby improving assembly efficiency.

[0093] Based on this, in order to improve the adaptability of the aforementioned front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25 to the accommodating space 111, in the embodiments of this application, each panel is, for example, an integral foamed panel. This integral foamed panel includes a foam layer and a support plate. The foam layer is located on the side of the support plate facing the inner wall of the accommodating space 111. The foam layer is used to fix to the inner wall of the accommodating space 111. In this way, on the one hand, compared to a sandwich-style panel structure, under the premise of the same thickness, the integral foamed panel allows for a thicker foam layer, thereby improving the insulation effect; on the other hand, the foam layer can easily adapt to the inner wall of the accommodating space 111.

[0094] For example, the foam layer may be made of polyurethane, among other things. The support plate may be made of fiberglass, among other things.

[0095] In some embodiments of this application, please refer to Figure 8 The top plate 22 includes a top plate body 221, a top left flange 222, and a top right flange 223.

[0096] The top plate body 221 can be flat. For example, the top plate body 221 can be rectangular flat or irregularly shaped flat.

[0097] The top left flange 222 is located at the left end of the top plate body 221 and folds downward. The top right flange 223 is located at the right end of the top plate body 221 and folds downward. In this way, the top plate 22 can be a dome-shaped structure, which has better structural strength and stability. Furthermore, the flange design also facilitates the design of the step section 26 described below.

[0098] In other embodiments, the top plate 22 may further include a front top flange (not shown) and a rear top flange (not shown). The front top flange is located at the front end of the top plate body 221 and folds downward. The rear top flange is located at the rear end of the top plate body 221 and folds downward.

[0099] For example, when the top plate 22 is a splicing structure P formed by multiple splicing plates P1 spliced ​​together in the front-back direction, each splicing plate P1 of the top plate 22 includes a part of the top plate body 221, a part of the top left flange 222 and a part of the top right flange 223.

[0100] For example, the thickness of the top plate 22 is the same everywhere. This simplifies the processing of the top plate 22.

[0101] In some embodiments of this application, the base plate 23 includes a base plate body 231, a bottom left flange 232, and a bottom right flange 233.

[0102] The base plate body 231 can be flat. For example, the base plate body 231 can be rectangular flat or irregularly shaped flat.

[0103] The bottom left flange 232 is located at the left end of the base plate body 231 and folds upward, while the bottom right flange 233 is located at the right end of the base plate body 231 and folds upward. This design improves the structural strength and stability of the base plate 23. Furthermore, the flanges facilitate the installation of the step portion 26 described below.

[0104] In other embodiments, the base plate 23 may further include a front bottom flange (not shown) and a rear bottom flange (not shown). The front bottom flange is located at the front end of the base plate body 231 and folds upward. The rear bottom flange is located at the rear end of the base plate body 231 and folds upward.

[0105] In related technologies, the peripheral surfaces of each panel of the carriage structure 10 are flat. When fixing the panels, the peripheral surface of one panel often overlaps the outer peripheral edge of another panel at a right angle, resulting in a large gap between the two adjacent panels and poor sealing. Moreover, during installation, it is necessary to manually draw lines on the outer peripheral edge of another panel or use tooling for positioning and installation, which makes the installation process complicated and inefficient.

[0106] Based on this, please refer to some embodiments of this application. Figure 9 and Figure 10 In the front panel 21, top panel 22, bottom panel 23, left panel 24, and right panel 25, a step 26 is formed at the adjacent end of any two adjacent panels, and the steps 26 of any two adjacent panels are compatible. This serves two purposes: firstly, the steps 26 of two adjacent panels provide positioning for fixing them, improving the reliability and structural stability of the fit and increasing assembly efficiency; secondly, because the steps 26 are uneven, they increase the mating area between the two adjacent panels, resulting in a tighter fit and improved sealing and insulation of the insulated inner compartment 2.

[0107] In some embodiments of this application, the stepped portions 26 of any two adjacent panels are fixedly connected by structural adhesive. This achieves two advantages: firstly, the two adjacent panels are non-removable, improving the structural strength and stability of the insulated inner compartment 2; secondly, the risk of structural adhesive cracking is low, allowing for improved sealing between adjacent panels, thereby enhancing the insulation capacity of the compartment structure 10. Furthermore, compared to riveting, structural adhesive bonding avoids exposed structural adhesive and is more aesthetically pleasing.

[0108] Based on the above description, in this embodiment, the overall assembly sequence of the carriage structure 10 is as follows: the top plate 22 is fixed to the top wall surface 1113 of the carriage body 11, and the bottom plate 23 is fixed to the bottom wall surface 1114 of the carriage body 11. Then, tooling struts are used to support the top plate 22 and the bottom plate 23. Next, structural adhesive is applied to the front wall surface of the carriage body 11 at the step portion 26 of the top plate 22 and the bottom plate 23, and the front panel 21 is pushed in. When the step portion 26 of the front panel 21 is completely embedded in the step portion 26 of the top plate 22 and the bottom plate 23, the installation of the front panel 21 is completed.

[0109] Similar to the installation of the front panel 21 described above, multiple splice plates P1 of the left panel 24 are pushed in sequentially. Structural adhesive can be applied to the concave-convex structure P11 of the already assembled splice plate P1 to facilitate a secure connection when the next splice plate P1 to be installed is joined to the already assembled splice plate P1.

[0110] Similar to the installation of the front panel 21 described above, multiple splice plates P1 of the right panel 25 are pushed in sequentially. Structural adhesive can be applied to the concave-convex structure P11 of the already assembled splice plate P1 to facilitate a secure connection when the next splice plate P1 to be installed is joined to the already assembled splice plate P1.

[0111] In some embodiments of this application, to further improve the thermal insulation performance of the carriage structure 10, please refer back to the previous section. Figure 4 and Figure 5 The inner wall of the rear tailgate 12 is provided with an insulated inner panel 3.

[0112] Based on this, the surface of the inner wall of the insulation inner panel 3 facing the rear tailgate 12 has a similar shape to the inner wall of the rear tailgate 12. In this way, the fit between the two is better, and the gap between them is very small or almost non-existent, which helps to improve the space utilization of the vehicle body structure 10.

[0113] Furthermore, when the inner wall surface of the tailgate 12 is uneven, since the surface of the inner insulation panel 3 facing the inner wall surface of the tailgate 12 is similar in shape to the inner wall surface of the tailgate 12, the convex part of the inner insulation panel 3 corresponds to the concave part of the inner wall surface of the tailgate 12, and the concave part of the inner insulation panel 3 corresponds to the convex part of the inner wall surface of the tailgate 12. When the inner wall surface of the tailgate 12 and the inner insulation panel 3 are fitted together, it is beneficial to use the similarity between the two to play a positioning role and improve assembly efficiency.

[0114] In some embodiments of this application, the carriage body 11 includes an outer sheet metal panel, an inner sheet metal panel, and a reinforcing bracket disposed between the outer sheet metal panel and the inner sheet metal panel. The aforementioned insulated inner compartment 2 is located within the inner sheet metal panel.

[0115] In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples without contradicting each other.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
