[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The core of the present invention is to provide an equipment cabin skeleton module, which reduces the difficulty of assembly.

[0037] For the specific embodiment of the equipment compartment skeleton module provided by the present invention, please refer to Figures 1 to 8 , including components such as a transverse bending beam 3, an end plate bracket 5, an upper side beam 1, and a lower side beam 2. The upper side beam 1 and the lower side beam 2 are made of aluminum profiles, and the transverse bending beam 3 and the end plate bracket 5 include a carbon fiber composite structure. Among them, the different components are fixed together by bolts, which is convenient for assembly and disassembly, eliminates the need for connecting angle irons, welding ribs and other structures, and improves the fatigue strength of the structure. Specifically, the upper side beam 1 and the lower side beam 2 are respectively bolted to the transverse bending beam 3, and specifically four bolts can be used for each. Of course, in other embodiments, welding and other methods can also be used.

[0038] like Figure 1 and Figure 2 As shown, the transverse bending beam 3 is an integrated structure, specifically, no connection and assembly operations are required in its length direction. The transverse bending beam 3 includes a transverse beam 31 and a bending beam 32 in the length direction. Specifically, as shown in FIG. Figure 1 As shown, the transverse curved beam 3 comprises a transverse beam 31 and curved beams 32 located above each end of the transverse beam 31. The transverse curved beam 3 is generally U-shaped along its length. Since the transverse beam 31 and curved beam 32 do not require assembly, the number of connectors between components can be reduced, facilitating lightweighting and simplifying assembly, as there is no need to position and assemble the transverse beam 31 and curved beam 32 separately. Furthermore, the transverse beam 31 extends along a second direction Y. The first direction X, the second direction Y, and the vertical direction can be perpendicular to each other, and in other embodiments, other angles are also possible.

[0039] In order to ensure the structural strength of the transverse bending beam 3, Figure 3As shown, the transverse curved beam 3 comprises an inner core 13 and an outer sleeve 12 secured to the outer surface of the inner core 13, resulting in a solid structure that ensures structural strength. During processing, the integral inner core 13 is first machined into a U-shape, and then the outer sleeve 12 is applied to the outer surface. Accordingly, both the transverse beam 31 and the curved beam 32 employ this outer sleeve 12 and inner core 13 configuration.

[0040] like Figure 1 As shown, the upper and lower side rails 1 and 2 extend along a first direction X. The two upper side rails 1 are located on the upper layer, and the two lower side rails 2 are located on the lower layer. The top ends of the two curved beams 32 are fixed to the two upper side rails 1, and the bottom ends of the two curved beams 32 are fixed to the two lower side rails 2. Furthermore, the lower side rails 2 are located outside the groove of the U-shaped transverse curved beam 3.

[0041] In this embodiment, an integrated transverse curved beam 3 is used to connect the upper side beam 1 and the lower side beam 2 respectively. Compared with the split transverse beam 31 and curved beam 32 in the prior art, the difficulty of assembly can be reduced, the assembly steps can be reduced, the demand for fasteners such as bolts can be reduced, and the complexity of disassembly and installation of fasteners such as bolts is reduced, which is conducive to lightweighting of the equipment. At the same time, the maintenance and repairability can be guaranteed. Without disassembling the skeleton module, the separate transverse curved beam 3 can be disassembled. The transverse curved beam 3 and the upper side beam 1 and the lower side beam 2 are simple and convenient to install, which can improve the efficiency of production installation and maintenance.

[0042] For the setting mode of the transverse bending beam 3, Figure 3 As shown, the inner core 13 is a foam sandwich core, and the outer shell 12 is a carbon fiber composite shell. On the premise of meeting the static strength load and fatigue strength load, the carbon fiber composite material is used, which has the advantage of lightweight.

[0043] Among them, such as Figure 3 As shown, the outer shell 12 includes a first carbon fiber layer 121 and a second carbon fiber layer 122. The first carbon fiber layer 121 is a flat plate structure, and the second carbon fiber layer 122 is fixed to one side of the first carbon fiber layer 121. The middle portion of the second carbon fiber layer 122 protrudes away from the first carbon fiber layer 121, forming an inner cavity between the middle portion of the second carbon fiber layer 122 and the middle portion of the first carbon fiber layer 121. The inner core 13 is fixed in this inner cavity. At this time, the inner core 13 and the middle portions of the first and second carbon fiber layers 121 and 122 form the main beam 33 of the transverse bending beam 3. The two ends of the second carbon fiber layer 122 are respectively bonded and fixed to the two ends of the first carbon fiber layer 121, and respectively form the side beam plates 34 on both sides of the main beam 33.

[0044] The first carbon fiber layer 121 and the second carbon fiber layer 121 can each include multiple layers of carbon fiber fabric or carbon fiber plies 123. Furthermore, two side beams 34 are located on either side of the main beam body 33 in the first direction X. The transverse bending beam 3 can be fixed to the lower side beam 2 via the side beams 34, specifically by bolting.

[0045] Since the outer shell 12 is divided into two parts to wrap different positions of the inner core 13, the inner core 13 can be completely wrapped, which can reduce the processing difficulty. Figure 3 As shown, on a special mold, a foam core is placed on the mold as the inner core 13, and multiple layers of carbon fiber fabrics in different directions are manually laid on the bottom layer and surface of the foam core, respectively serving as the first carbon fiber layer 121 and the second carbon fiber layer 122. After the laying is completed, the beam structure is formed by an autoclave molding method, thereby processing the integrated transverse curved beam 3 overall structure of the composite foam core outer layer structure.

[0046] In order to realize the connection between the transverse bending beam 3 and the upper side beam 1, Figure 2 and Figure 4 As shown, a hanger 4, specifically an aluminum alloy hanger, is added to the top of the curved beam 32. The curved beam 32 is fixed to the upper side beam 1 through the hanger 4 without being directly connected to the upper side beam 1.

[0047] By adding a hanger 4 to connect the upper rail 1 and the curved beam 32, a reliable connection between the two can be ensured, so that the connection position and connection strength can be adapted to the needs. In particular, when the outer shell 12 is a structure with two ends extending through it, that is, the outer shell 12 is an annular member that circumferentially wraps around the inner core 13, and the two free ends of the inner core 13 (corresponding to the top ends of the two curved beams 32) are exposed, when connected to the upper rail 1, it is difficult to ensure the connection strength when the upper rail 1 and the inner core 13, such as a foam sandwich core, are directly connected. However, adding a hanger 4 can cover the two ends of the outer shell 12 to protect the inner core 13, and the hanger 4 can be used to bolt the upper rail 1.

[0048] Specifically, if Figure 2 As shown, the hanger 4 is a U-shaped structure that is buckled onto the top of the curved beam 32. The hanger 4 includes two side panels 42 and a top panel 41 fixed between the tops of the two side panels 42. It should be noted that, as needed, the angle between the side panels 42 and the top panel 41 can be vertical, or other angles. The two side panels 42 are respectively fixedly connected to the outer sleeve 12, specifically by riveting. The top panel 41 covers the top surface of the curved beam 32, and the upper side beam 1 is fixed above the top panel 41, specifically by fitting together, and the top surface of the top panel 41 can also be a plane. Specifically, the two side panels 42 are respectively fixed to both sides of the main beam body 33 along the second direction Y, and accordingly, the two side panels 42 are respectively fixedly connected to the first carbon fiber layer 121 and the second carbon fiber layer 122. During assembly, the top of the curved beam 32 is inserted into the groove of the hanger 4, and then the side panels 42 are fixed to the curved beam 32 by riveting.

[0049] Specifically, if Figure 2 As shown, the side panels 42 are trapezoidal, with the edges of the top panel 41 fixed to the corresponding edges of the lower base (the longer of the two bases) of the trapezoidal panel. This creates a triangular support between the side panels 42 and the roof rail 1, enhancing the strength of the connection between the transverse curved beam 3 and the roof rail 1. This eliminates the need for welding stiffeners within the mold cavity of the roof rail 1 at the connection, eliminating the need for welded reinforcements and improving fatigue resistance.

[0050] Specifically, if Figure 2 As shown, the middle part of the top plate 41 covers the top surface of the main beam body 33, and the two sides extend out of the main beam body 33 in the first direction X and form a connecting plate 43. The hanger 4 is bolted to the upper side beam 1 through the connecting plate 43. At this time, the bolt connection avoids the inner core 13 to avoid damage to the inner core 13.

[0051] For the structure of the upper side beam 1, Figure 4 As shown, the roof rail 1 includes a plurality of upper sub-beams 11, for example, three, which are sequentially detachably connected along the first direction X. Thus, each part of the roof rail 1 can be repaired and replaced separately. Of course, in other embodiments, the roof rail 1 can also be integrally provided along the first direction X.

[0052] In order to realize the connection between adjacent upper beam bodies 11, Figure 4 As shown, two adjacent upper beam bodies 11 are respectively fixed to the hangers 4 to achieve splicing. The two upper beam bodies 11 are spliced ​​with the help of the hangers 4, and the two upper beam bodies 11 are assembled while connecting the curved beam 32 and the upper side beam 1.

[0053] It should be noted that the present embodiment uses the hanger 4 to connect the two upper beams 11, including the hanger 4 being completely connected to the joint of the two corresponding upper beams 11 to simultaneously connect the two upper beams 11 and the curved beam 32; and also includes the hanger 4 being partially connected to the joint of the two corresponding upper beams, and the hanger 4 being partially connected to the middle of a single upper beam 11 (i.e. Figure 5 As shown, this part of the hanger 4 is not used to realize the splicing of the upper beam body 11. Of course, in other embodiments, adjacent upper beam bodies 11 can also be fixedly connected together by means of pads and bolts, without the help of the hanger 4 for splicing.

[0054] For the structure of the lower side beam 2, Figure 4 As shown, the rocker 2 includes a plurality of lower sub-beams 21, for example, three, which are sequentially detachably connected along the first direction X. Thus, each part of the rocker 2 can be repaired and replaced separately. Of course, in other embodiments, the rocker 2 can also be integrally provided along the first direction X.

[0055] Among them, in order to realize the connection of adjacent lower beams, Figure 4 As shown, two adjacent lower sub-beams 21 are respectively fixed to two side beam plates 34 on the transverse curved beam 3. By connecting the two lower sub-beams 21 to one transverse curved beam 3 at the same time, the splicing of the two lower sub-beams 21 and the connection between the transverse curved beam 3 and the lower side beam 2 can be achieved at the same time.

[0056] It should be noted that the two lower beam bodies 21 are connected by means of the transverse curved beam 3 in this embodiment, including the transverse curved beam 3 being connected to the corresponding joints of the two lower beam bodies to simultaneously connect the two lower beam bodies 21 and the curved beam 32; and also including the transverse curved beam 3 being connected to the joints of the two lower beam bodies and the transverse curved beam 3 being connected to the middle part of the separate lower beam body 21 (i.e. Figure 5 As shown, this part of the transverse curved beam 3 is not used to realize the splicing of the lower sub-beams 21). Of course, in other embodiments, adjacent lower sub-beams 21 can also be fixedly connected together by pads and bolts without the help of transverse curved beams 3 for splicing.

[0057] Among them, in order to realize the modular assembly of the upper side beam 1 and the upper side beam 1 in the first direction X, the upper sub-beam body 11 in the upper side beam 1 and the lower sub-beam body 21 in the lower side beam 2 can be arranged in equal amounts in the first direction X. Among them, when the splicing of two adjacent upper sub-beam bodies 11 is connected to a hanger 4 set on a transverse bending beam 3, the transverse bending beam 3 is also used to realize the splicing of two adjacent lower sub-beam bodies 21.

[0058] In this embodiment, the upper side beam 1 and the lower side beam 2 are arranged in sections, and the upper side beam 1, the lower side beam 2 and each transverse curved beam 3 are separately connected by bolts. When the skeleton module is not removed from the vehicle, a single transverse curved beam 3 and each section of the upper and lower beams can be removed, which facilitates the inspection and replacement of the transverse curved beam 3, the upper side beam 1 and the lower side beam 2.

[0059] In addition, if Figure 7 and Figure 8 As shown, the lower side rail 2 includes a first lower panel 22 and a second lower panel 23, each extending along a first direction X. Both the first lower panel 22 and the second lower panel 23 are single-layer panels. One end of the second lower panel 23 is fixed to the bottom end of the first lower panel 22, and the two panels together form a bent panel. The first and second lower panels 22, 23 are each fixedly connected below the bottom end of the curved beam 32, specifically, they can fit within the bent portion of the bottom end of the curved beam.

[0060] Because this embodiment utilizes an integrated transverse curved beam 3, its inherent structural strength is relatively good, and the strength requirements can be met simply by securely connecting the lower end of the curved beam 32 to the lower rail 2. This eliminates the need for the lower rail 2 to utilize a profile with multiple cavities to stabilize the connection to the split transverse beam 31, as is common in the prior art. Furthermore, in this embodiment, the first lower side panel 22 and the second lower side panel 23 of the lower rail 2 are single-layer panels, reducing or eliminating cavities and providing a completely new cross-section. Only the necessary mounting surface structure for connection to the transverse curved beam 3 is retained. This simplifies the mold for the lower rail 2, reduces manufacturing complexity, reduces costs, and enables lightweighting of the lower rail 2.

[0061] Among them, such as Figure 4 , Figure 7 and Figure 8 As shown, the lower side beam 2 further includes a positioning plate 25 fixed below the second lower side plate 23. The positioning plate 25 has a positioning groove 251 in the middle portion. The end of the crossbeam 31 is inserted into the positioning groove 251, which can improve the installation stability of the crossbeam 31. Specifically, the portion of the main beam body 33 located at the crossbeam 31 extends into the positioning groove 251, and the portion of the side beam plate 34 located at the crossbeam 31 abuts against the positioning plate 25 along the second direction Y.

[0062] Among them, such as Figure 4 , Figure 7 and Figure 8 As shown, the lower side rail 2 also includes a third lower side plate 24 fixed below the second lower side plate 23. The third lower side plate 24 and the first lower side plate 22 are respectively connected to two opposite edges of the second lower side plate 23, specifically located at two opposite edges in the second direction Y. The first lower side plate 22, the second lower side plate 23, and the third lower side plate 24 form a Z-shaped structure. A certain gap may be provided between the third lower side plate 24 and the transverse bending beam 3 in the second direction Y to provide space for bolting the lower side rail 2 to other components. In this case, the positioning plate 25 is fixed to the bottom end of the third lower side plate 24, and the lower side rail 2 can be formed in one piece, for example, by bending.

[0063] Among them, such as Figure 8 As shown, the first lower plate 22 is fixed with a shaft hole 221 for rotating the skirt plate. The angle between the first lower plate 22 and the second lower plate 23 includes an obtuse angle, and the curved beam 32 is connected to one side of the obtuse angle ( Figure 8 (See the left side in the figure). The shaft hole 221 and the curved beam 32 are respectively provided on either side of the first lower side panel 22. The skirt panel is rotatably connected to the shaft hole 221 via the shaft. Since the remaining structure on the lower side panel 2 avoids the space directly below the first lower side panel 22, when the skirt panel is opened, it can be tilted downward around the shaft to the position directly below the shaft, in a vertical position. This increases the opening and closing angle of the skirt panel, reduces weight, and improves the convenience of equipment maintenance within the equipment compartment.

[0064] The equipment bay skeleton module provided by the present invention can be used as a central vehicle equipment bay skeleton module structure, used to connect and mount the equipment bay end panels, skirt panels, and floor panels. The integrated design of the crossbeam 31 and curved beam 32 optimizes the connection between the crossbeam and curved beam 32 and the upper side rail 1, reducing the number of bolt connections, simplifying the equipment bay skeleton module installation, and reducing the weight of the equipment bay skeleton. By reducing the cross-section of the lower side rail 2 and replacing the skirt panel's hook installation method with a profile pivot connection, the structural weight is reduced and serviceability is optimized.
