Description

Technical Field

[0001] This application relates to the field of vehicle equipment technology, and more particularly to a crossbeam assembly and a vehicle. Background Technology

[0002] A vehicle body roof typically includes a side panel structure and a crossbeam that is located in and connected to the side panel structure.

[0003] As a crucial structural component of the vehicle body, the roof beam must meet performance requirements under conditions such as collision, roof crush, bending, and torsion. Additionally, the beam is used to mount components such as the roof glass, interior and exterior trim, and electrical systems.

[0004] However, the crossbeams in the aforementioned technologies encroach on the headroom of vehicle occupants, and their weight is significant, affecting the vehicle's lightweight design. Utility Model Content

[0005] In view of this, embodiments of this application provide a crossbeam assembly and a vehicle to solve the technical problems in the above-mentioned related technologies where the crossbeam encroaches on the head space of the occupants in the vehicle and the crossbeam is heavy, affecting the lightweighting of the vehicle.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] This application provides a crossbeam assembly, which includes:

[0008] The body extends along a first direction and has a through groove extending along the first direction on one side facing the vehicle body. The through groove is at least used for mounting a sunroof sunshade hinge. Both ends of the body along the first direction are used to connect to the side structure.

[0009] The first support structure and the second support structure are respectively disposed at both ends of the body along the first direction, and both the first support structure and the second support structure are attached to the inner wall of the through groove.

[0010] The first support structure and the second support structure are respectively used to support the two ends of the main body.

[0011] This application provides a crossbeam assembly with a through groove extending through both ends in a first direction. At least components such as the sunroof sunshade hinge can be installed in the through groove. This design arranges the sunroof sunshade hinge inside the middle crossbeam cavity, reducing the encroachment of the sunshade hinge on the head space of the occupants in the vehicle.

[0012] The through-slot design gives the body a certain cavity structure, which increases the moment of inertia of the body's cross-section. The moment of inertia is an important parameter measuring a cross-section's resistance to bending deformation; the larger the moment of inertia, the stronger the bending resistance of the cross-section. The through-slot increases the body's deformability, thereby improving its energy absorption capacity. Under impact loads, the body can absorb some energy through deformation, reducing the damage to the beam caused by the impact load.

[0013] The first and second support structures are respectively located at both ends of the main body and fit against the inner wall of the through groove to support both ends of the main body. This design can effectively disperse and transfer the load acting on the main body, enhance the overall structural stability of the beam, and enable it to better withstand bending loads.

[0014] In addition, since the through channel is an open channel structure and the main body does not use additional stiffeners to close the opening of the through channel, the weight of the main body is lighter than that of the crossbeam in the prior art, which helps to reduce the weight of the vehicle.

[0033] The second overlapping surface is connected to the second side support plate and the second bottom support plate, and is used to connect with the surface of the side structure.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0068] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0069] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0070] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0071] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0072] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0073] The crossbeams in related technologies encroach on the headroom of vehicle occupants, and their significant weight affects vehicle lightweighting. This problem arises because the crossbeams in existing roof designs are formed by welding two sheet metal panels together along the height of the vehicle body. This welding creates a cavity between the two panels, which can absorb the crossbeam's moment of inertia and deformation energy. However, this cavity is closed, making it impossible to install components such as sunshade hinges. The hinges can only be installed on the side of the sheet metal facing the passenger compartment, causing the entire roof to sag towards the vehicle body. This results in a lower headroom in the passenger compartment, thus encroaching on the headroom of the occupants.

[0074] Furthermore, the crossbeams in existing technologies are made by welding two sheet metal parts together, which results in a larger crossbeam weight and increases the overall weight of the vehicle, which is not conducive to lightweight vehicle design.

[0075] To address the aforementioned issues, this application provides a crossbeam assembly and a vehicle. The body of the crossbeam assembly has a through groove extending through both ends in a first direction, and at least components such as a sunroof sunshade hinge or a sunroof sunshade bracket can be installed in the through groove. This design arranges the sunroof sunshade hinge inside the middle crossbeam cavity, reducing the encroachment of the sunshade hinge on the head space of the occupants inside the vehicle.

[0076] The through-slot design gives the body a certain cavity structure, which increases the moment of inertia of the body's cross-section. The moment of inertia is an important parameter measuring a cross-section's resistance to bending deformation; the larger the moment of inertia, the stronger the bending resistance of the cross-section. The through-slot increases the body's deformability, thereby improving its energy absorption capacity. Under impact loads, the body can absorb some energy through deformation, reducing the damage to the beam caused by the impact load.

[0077] The first and second support structures are respectively located at both ends of the main body and fit against the inner wall of the through groove to support both ends of the main body. This design can effectively disperse and transfer the load acting on the main body, enhance the overall structural stability of the beam, and enable it to better withstand bending loads.

[0078] In addition, since the through channel is an open channel structure and the main body does not use additional stiffeners to close the opening of the through channel, the weight of the main body is lighter than that of the crossbeam in the prior art, which helps to reduce the weight of the vehicle.

[0079] The beam assembly provided in this application is described below with reference to the accompanying drawings and specific embodiments.

[0080] Reference Figures 1 to 2 This application provides a crossbeam assembly for connection to the side structure 20 of a vehicle roof. The crossbeam assembly may include a body 100, a first support structure 200, and a second support structure.

[0081] Body 100 along the first direction (e.g.) Figure 1 The body 100 extends in the X direction and has a through groove 110 extending in the first direction on one side facing the vehicle body. The through groove 110 can connect the two opposite ends of the body 100 in the first direction.

[0082] Reference Figure 4 and Figure 5 The through groove 110 is used at least to install the sunroof sunshade hinge 10, and the two ends of the body 100 along the first direction are used to connect with the side structure 20. The through groove 110 can also be used to install the sunroof sunshade bracket 30.

[0083] This design places the sunroof sunshade's pivot inside the crossbeam assembly cavity, reducing the sunshade pivot's encroachment on the headroom of the occupants.

[0084] The through-slot 110 design gives the body 100 a certain cavity structure, which increases the moment of inertia of the body 100's cross-section. The moment of inertia is an important parameter for measuring a cross-section's resistance to bending deformation; the larger the moment of inertia, the stronger the cross-section's bending resistance. The through-slot 110 increases the deformation capacity of the body 100, thereby improving its energy absorption capacity. When subjected to impact loads, the body 100 can absorb some energy through deformation, reducing the damage to the beam caused by the impact load.

[0085] In some embodiments, the first direction may be the width direction of the vehicle.

[0086] The first support structure 200 and the second support structure are respectively disposed at both ends of the body 100 along the first direction. Both the first support structure 200 and the second support structure are attached to the inner wall of the through groove 110, and both ends of the body 100 are connected to the side wall structure 20 through the first support structure 200 and the second support structure. The first support structure 200 and the second support structure are respectively used to support both ends of the body 100.

[0087] Specifically, one end of the first support structure 200 is attached to the inner wall of one end of the through groove 110 along the first direction, and the other end of the first support structure 200 is used to connect to the side enclosure structure 20. This achieves the connection between the body 100 and one side of the side enclosure structure 20 through the first support structure 200. One end of the second support structure is attached to the inner wall of the other end of the through groove 110 along the first direction, and the other end of the second support structure is used to connect to the other side of the side enclosure structure 20, thereby achieving the connection between the body 100 and the other side of the side enclosure structure 20 through the second support structure.

[0088] The first support structure 200 and the second support structure are respectively disposed at both ends of the body 100 and fit against the inner wall of the through groove 110 to support both ends of the body 100. This design can effectively disperse and transfer the load acting on the body 100, enhance the overall structural stability of the beam, and enable it to better withstand bending loads.

[0089] Since the through slot 110 is an open slot structure and the body 100 does not use additional stiffeners to close the slot opening of the through slot 110, the weight of the body 100 is lighter than that of the crossbeam in the prior art, which helps to reduce the weight of the vehicle.

[0090] Reference Figures 1 to 3 In some embodiments, the body 100 may include a top plate 120, a first side plate 130, and a second side plate 140 extending along a first direction. The top plate 120 has a width direction (e.g., Figure 3The top plate 120, the first side plate 121, and the second side plate 122 are opposite each other in the Y direction. The first side plate 130 is disposed on the first side 121, and the second side plate 140 is disposed on the second side 122. The top plate 120, the first side plate 130, and the second side plate 140 together form a through groove 110.

[0091] In some embodiments, the top plate 120, the first side plate 130, and the second side plate 140 can be an integral structure. For example, the top plate 120, the first side plate 130, and the second side plate 140 can be formed by stamping, or by casting or die casting from a flat sheet metal.

[0092] The main body 100 is formed by the top plate 120, the first side plate 130 and the second side plate 140 together forming a through groove 110. This structure gives the main body 100 a certain cavity space, providing space for installing components such as the sunroof shade curtain pivot 10, and also providing a basis for subsequent structural optimization.

[0093] The main body 100 has a simple structure and is easy to manufacture. While ensuring the structural strength and torsional resistance of the main body 100, the manufacturing efficiency of the main body 100 can be improved, thereby improving the production efficiency of the crossbeam assembly.

[0094] Reference Figures 1 to 3 In some embodiments, the surface of the first support structure 200 facing the body 100 can be completely fitted with the top plate 120, the first side plate 130, and the second side plate 140. The body 100 may also include a first connecting plate 150 and a second connecting plate 160.

[0095] One end of the first connecting plate 150 is connected to the side of the first side plate 130 facing away from the top plate 120, and the other end extends outward from the first side plate 130 toward the through groove 110. One end of the second connecting plate 160 is connected to the side of the second side plate 140 facing away from the top plate 120, and the other end extends outward from the first connecting plate 150.

[0096] The first connecting plate 150 and the second connecting plate 160 are connected to the first side plate 130 and the second side plate 140 respectively, and extend outward toward the through groove 110. This design increases the connection points of the body 100, provides more connection positions for the subsequent support structure and reinforcement 300, and enhances the overall structural stability of the beam assembly.

[0097] Reference Figures 1 to 3 In some embodiments, the body 100 may further include a first flange 170 and a second flange 180. The first flange 170 is disposed at one end of the first connecting plate 150 facing away from the first side plate 130, and the first flange 170 is folded toward the top plate 120. The second flange 180 is disposed at one end of the second connecting plate 160 facing away from the second side plate 140, and the second flange 180 is folded toward the top plate 120.

[0098] The first flange 170 and the second flange 180 are respectively disposed at the ends of the first connecting plate 150 and the second connecting plate 160, and fold towards the top plate 120. The flange structure can increase the bending resistance of the body 100, enhance the structural stability of the body 100, enable it to better withstand bending loads, and at the same time avoid scratches when the side curtain airbags are deployed, thereby improving the passive safety performance of the vehicle.

[0099] In some embodiments, the first support structure 200 also has a flange structure corresponding to the first flange 170 and the second flange 180, and the flange on the first support structure 200 will fit against the side of the first flange 170 and the second flange 180 facing the vehicle interior.

[0100] In some embodiments, the second support structure is exactly the same as the first support structure 200, and the second support structure has the same structural parts as the first support structure 200 to ensure the uniformity of force on both ends of the body 100 along the first direction.

[0101] Reference Figure 1 and Figure 6 In some embodiments, the first support structure 200 may include a top support plate 210, a first side support plate 220, and a second side support plate 230.

[0102] The top support plate 210 is correspondingly disposed with the top plate 120, and the top support plate 210 is attached to the surface of the top plate 120 facing the through groove 110. The first side support plate 220 is connected to one side of the top support plate 210 along the width direction, and the first side support plate 220 is attached to the surface of the first side plate 130 facing the through groove 110. The second side support plate 230 is connected to the other side of the top support plate 210 along the width direction, and the second side support plate 230 is attached to the surface of the second side plate 140 facing the through groove 110.

[0103] The first support structure 200 may include a top support plate 210, a first side support plate 220, and a second side support plate 230, which are respectively attached to the inner surfaces of the top plate 120, the first side plate 130, and the second side plate 140. This design allows the support structure to fit tightly against the body 100, enabling better load distribution and transfer, and enhancing the overall structural stability of the crossbeam assembly. This allows the crossbeam assembly to better withstand loads, thereby improving its performance and meeting the performance requirements of the vehicle under conditions such as collision, top pressure, bending, and torsion. Simultaneously, the tight fit design also helps improve the bending resistance of the crossbeam assembly.

[0104] Reference Figure 6 In some embodiments, the first support structure 200 may further include a first bottom support plate 240, a second bottom support plate 250, a first overlapping surface 260, and a second overlapping surface 270.

[0105] The first bottom support plate 240 has one end connected to the side of the first side support plate 220 facing away from the top support plate 210, and the other end extends outward from the first side support plate 220 toward the through groove 110. The second bottom support plate 250 has one end connected to the side of the second side support plate 230 facing away from the top support plate 210, and the other end extends outward from the first bottom support plate 240.

[0106] The main body 100 has a first connecting plate 150 and a second connecting plate 160. The first bottom support plate 240 is connected to the surface of the first connecting plate 150 facing the interior of the vehicle, and the second bottom support plate 250 can also be connected to the surface of the second connecting plate 160 facing the interior of the vehicle, thereby further increasing the number of connection points between the first support structure 200 and the main body 100.

[0107] This design allows for better load distribution and transfer, enhancing the overall structural stability of the crossbeam assembly. It enables the crossbeam assembly to better withstand loads, thereby improving its performance and meeting the vehicle's performance requirements under conditions such as collisions, roof crush, bending, and torsion. Simultaneously, the close-fitting design also helps improve the crossbeam assembly's bending resistance.

[0108] The first overlapping surface 260 is connected to the first side support plate 220 and the first bottom support plate 240, and the first overlapping surface 260 is used to connect with the surface of the side structure 20. The second overlapping surface 270 is connected to the second side support plate 230 and the second bottom support plate 250, and the second overlapping surface 270 is used to connect with the surface of the side structure 20.

[0109] By increasing the overlapping surfaces, the connection points between the main body 100 and the side structure 20 can be increased, making the connection between the main body 100 and the side structure 20 more robust, improving the reliability of the connection, and ensuring the force transmission effect. This improves the overall performance of the main body 100 and the side structure 20, enabling them to better withstand loads and meet the performance requirements of the vehicle under various working conditions.

[0110] Reference Figure 1 In some embodiments, the side of the top support plate 210 facing the top plate 120 may include a first connecting portion 211, a second connecting portion 212, and a protrusion 213. The first connecting portion 211 is connected to the inner wall of the top plate 120 facing the through groove 110. The second connecting portion 212 is spaced apart from the first connecting portion 211 along a first direction and is used to connect to the side structure 20. The protrusion 213 is disposed between the first connecting portion 211 and the second connecting portion 212, and the protrusion 213 protrudes towards the top plate 120 relative to the first connecting portion 211 and the second connecting portion 212, and the surface of the protrusion 213 facing the top plate 120 is flush with the surface of the top plate 120 facing away from the inside of the through groove 110.

[0111] The top support plate 210 includes a first connecting portion 211, a second connecting portion 212, and a protrusion 213. The protrusion 213 protrudes towards the top plate 120 relative to the first connecting portion 211 and the second connecting portion 212, and the protruding surface is flush with the surface of the top plate 120 facing away from the inside of the through groove 110. This design makes the connection between the first support structure 200 and the body 100 tighter, while ensuring the flatness of the side of the crossbeam assembly facing outwards from the vehicle, without affecting the installation of other components, such as the installation of the roof glass.

[0112] Furthermore, the raised surface is flush with the surface of the top plate 120 facing away from the inside of the through groove 110, which helps to transmit force between the first support structure 200 and the body 100.

[0113] In some embodiments, the side structure 20 has a mounting portion, and a second connecting portion 212 is used to connect to the surface of the mounting portion facing the interior of the vehicle, while the surface of the mounting portion facing the exterior of the vehicle is flush with the surface of the protrusion 213, so as to facilitate the transmission of force between the side structure 20 and the first support structure 200.

[0114] Reference Figure 1 and Figure 2 In some embodiments, the beam assembly may further include a reinforcing member 300, which is disposed on the side of the first support structure 200 facing away from the body 100, and the reinforcing member 300 is used to connect the first support structure 200 to the side structure 20.

[0115] By setting the reinforcing member 300, the connection between the middle crossbeam and the side structure 20 is more robust, and the rigidity of the connection point is higher, thereby improving the overall performance of the middle crossbeam and the side structure 20, enabling it to better bear the load and meet the performance requirements of the vehicle under various working conditions.

[0116] In some embodiments, the reinforcing member 300 may have two members, one of which is used to connect the first support structure 200 to the side structure 20, and the other of which is used to connect the second support structure to the side structure 20.

[0117] Reference Figure 1 and Figure 2 In some embodiments, the reinforcement 300 may include a top reinforcement plate 310, a first side reinforcement plate 320, and a second side reinforcement plate 330.

[0118] The top reinforcing plate 310 is connected to the inner bottom wall of the first support structure 200 facing the through groove 110.
