Description

Technical Field

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

[0002] In a vehicle body, the roof crossbeam is one of the main skeletal structures of the roof. It is generally connected between the roof side beams on the left and right sides. The roof crossbeam not only supports the outer roof panel or the sunroof glass, but also serves as a channel for transmitting and dispersing the collision force during a vehicle collision.

[0003] Currently, traditional roof crossbeams are typically made of stamped sheet metal and can be fastened to the roof outer panel or a specially designed crossbeam outer panel to form a cavity structure, thereby increasing the structural strength of the roof crossbeam. However, since the roof crossbeam generally forms a single-cavity structure, its structural strength remains relatively weak, which is not conducive to improving the rigidity and modal characteristics of the vehicle body roof, and thus makes it difficult to contribute to improving the overall quality of the vehicle. Utility Model Content

[0004] In view of this, this application aims to provide a roof crossbeam that can improve the rigidity and modal characteristics of the vehicle body roof, thereby enhancing the overall quality of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A roof beam, suitable for installation on the top of a vehicle, includes an upper beam plate and a lower beam plate;

[0007] The lower plate of the crossbeam has a middle portion and end portions located on the left and right sides, and the width of the middle portion in the front-rear direction of the vehicle is greater than the width of the end portions on both sides in the front-rear direction of the vehicle.

[0008] The middle part has a recessed groove, and the middle part is provided with a raised rib located in the groove. The raised rib extends along the left and right direction of the whole vehicle, and there are multiple raised ribs arranged at intervals.

[0009] After the upper plate and the lower plate of the crossbeam are connected, the multiple raised ribs divide the groove into multiple cavities arranged sequentially.

[0010] Furthermore, both the front and rear edges of the middle portion have upwardly protruding flanges, and the groove is defined between the flanges on both sides.

[0011] The plurality of protruding ribs include a front protruding rib disposed near the front side of the flange, and a rear protruding rib disposed near the rear side of the flange;

[0012] The plurality of cavities include a front cavity located in front of the front protruding rib, a rear cavity located behind the rear protruding rib, and a middle cavity located between the front protruding rib and the rear protruding rib.

[0013] Furthermore, the front cavity and the middle cavity are connected by front connecting openings located on the left and right sides of the front protruding rib; and / or,

[0014] The rear cavity and the middle cavity are connected by rear connecting ports located on the left and right sides of the rear protruding rib.

[0015] Furthermore, the lower plate of the crossbeam is provided with a protrusion located between the front protruding rib and the rear protruding rib;

[0016] The protrusion extends along the left-right direction of the vehicle, and the protrusion is spaced apart from the front protrusion and from the rear protrusion.

[0017] Furthermore, the protrusion height of the protrusion is lower than that of the protruding rib; and / or,

[0018] The protrusion extends longer than the rib in the left-right direction of the vehicle, and both ends of the protrusion are positioned outward relative to the rib.

[0019] Furthermore, the lower plate of the crossbeam is provided with a front connecting rib connecting the protrusion and the front protruding rib; and / or,

[0020] The lower plate of the crossbeam is provided with a rear connecting bar that connects the protrusion and the rear protruding bar.

[0021] Furthermore, both ends of the aforementioned end portions are formed with recessed grooves;

[0022] After the upper plate and the lower plate of the crossbeam are connected, the grooves on the end portions at both ends form cavities, and the cavities at both ends are in communication with at least a portion of the cavity.

[0023] Furthermore, the lower plate of the crossbeam includes a lower plate body and connecting plates connected to the left and right sides of the lower plate body;

[0024] The lower plate body has a main body located in the middle and extension ends located on the left and right sides, and the width of the main body in the front-rear direction of the vehicle is greater than the width of the extension ends on both sides in the front-rear direction of the vehicle.

[0025] The main body constitutes the middle part, each of the extended ends is connected to the connecting plate on the same side, and the extended ends and the connecting plate on the same side together constitute the end part.

[0026] Furthermore, from the perspective of the vehicle's vertical direction, the outline of the upper plate of the crossbeam follows the shape of the lower plate of the crossbeam.

[0027] Compared with related technologies, this application has the following advantages:

[0028] (1) The roof beam described in this application makes the width of the middle part of the lower plate of the beam greater than the width of the end parts on both sides, and forms a groove in the middle part, provides multiple raised ribs in the groove, and uses the multiple raised ribs to separate multiple cavities arranged in sequence in front and behind, thereby increasing the structural strength of the roof beam and improving the rigidity and modality of the vehicle body top by utilizing the synergy between each raised rib and each cavity structure, which is conducive to improving the overall quality of the vehicle.

[0029] (2) The front and rear sides of the middle part are flanged, the groove is defined by the flanges on both sides, and the protruding ribs include the front protruding ribs and the rear protruding ribs, and the multiple cavities include the front cavity, the middle cavity and the rear cavity. This not only facilitates the forming of the groove, but also facilitates the setting of each protruding rib on the lower plate of the crossbeam, and facilitates the design of multiple cavities.

[0030] (3) The front cavity is connected to the middle cavity through the front connecting ports on both sides of the front protrusion rib, and the rear cavity is connected to the middle cavity through the rear connecting ports on both sides of the rear protrusion rib. This allows the electrophoretic liquid to flow between the cavities during the electrophoresis process by utilizing the cavity structure to increase the strength of the roof beam structure, which helps to ensure the electrophoresis effect.

[0031] (4) By setting a protrusion between the front and rear ribs and extending the protrusion along the left and right directions of the vehicle, the structural strength of the lower plate of the crossbeam can be further increased by the protrusion, which helps to better increase the overall structural strength and rigidity of the roof crossbeam and is beneficial to the improvement of the rigidity and modality of the vehicle top.

[0032] (5) The height of the protrusion is lower than that of the rib, which can prevent excessive stretching of the material of the lower beam plate while forming the protrusion, thus avoiding adverse effects on the structural performance of the lower beam plate. The extension length of the protrusion is greater than that of the rib, and both ends of the protrusion are set outward relative to the rib. The protrusion can be used to strengthen the structure of the lower beam plate near both ends. While the rib achieves the main strengthening function, the auxiliary strengthening structure of the protrusion can be used to make the lower beam plate as a whole have better rigidity and strength.

[0033] (6) The protrusion and the front protrusion are connected by the front connecting bar, and the protrusion and the rear protrusion are connected by the rear connecting bar. This can effectively connect the protrusion and each protrusion to form a frame-type rib structure, which can enable the protrusion and each protrusion to work together better and fully improve the overall structural performance of the lower plate of the crossbeam and the top cover crossbeam.

[0034] (7) The end portions at both ends are also formed with grooves, and the grooves are used to form cavities, and the formed cavities are connected with the cavities in the middle portion. This not only increases the structural strength at both ends of the top cover beam, but also cooperates with the multiple cavities formed in the middle portion, so that the top cover beam as a whole has good structural strength, which helps to ensure the improvement of the rigidity and modality of the top of the vehicle body. It also facilitates the full flow of the electrophoretic liquid between the middle portion and the end portions on both sides during the electrophoresis of the vehicle body, thus ensuring the electrophoresis effect.

[0035] (8) The lower plate of the crossbeam is mainly composed of the lower plate body and the connecting plates on both sides, and the lower plate body includes the main body and the extension ends on both sides, and the main body constitutes the middle part, and the extension ends on each side and the connecting plates together constitute the end part. This facilitates the design and preparation of the lower plate of the crossbeam, and facilitates the forming of various ribs or protrusions on the lower plate of the crossbeam, which helps to reduce the design and manufacturing cost of the lower plate of the crossbeam.

[0036] This application also proposes a vehicle, the top of which is provided with a roof beam as described above.

[0037] Furthermore, a mounting base is provided at the bottom of the top cover crossbeam, the mounting base being used to install electrical components on the vehicle roof;

[0038] The mounting base is connected to the lower plate of the crossbeam by several connectors, and the connectors are connected to the location of the cavity.

[0039] The vehicle described in this application, by providing the roof crossbeam as described above, can increase the structural strength of the roof crossbeam, improve the rigidity and modality of the vehicle body roof, and thus improve the overall quality of the vehicle.

[0040] Furthermore, by connecting the mounting base to the lower plate of the crossbeam via a connector, and by connecting the connector to the cavity on the lower plate of the crossbeam, it is not only convenient to realize the connection arrangement of the mounting base on the top cover crossbeam, but also to utilize the large rigidity of the cavity position to improve the rigidity of the mounting point and ensure the stability of the mounting base installation.

[0065] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0066] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0067] An embodiment of the first aspect of this application provides a roof beam suitable for installation on the top of a vehicle. Through its innovative structural design, the roof beam of this embodiment can increase the structural strength of the roof beam, thereby improving the rigidity and modal characteristics of the vehicle body top and thus contributing to the improvement of the overall quality of the vehicle.

[0068] In related technologies, the roof beam, as the main skeletal structure of the vehicle roof, plays a crucial role in the rigidity and modal characteristics of the vehicle roof.

[0069] On the top of the vehicle body, the roof beam is generally connected between the roof side beams on the left and right sides. The roof beam serves two purposes: firstly, it supports the outer roof panel or the sunroof glass; secondly, in the event of a collision, especially when the top of the vehicle body is subjected to pressure, the roof beam acts as a channel for transmitting the impact force on the top of the vehicle body, thus dispersing the impact force and reducing the damage caused by the collision.

[0070] Currently, in traditional vehicle body structure design, the roof crossbeam is generally made of stamped sheet metal, typically using steel plates less than 1mm thick, and usually employs a uniform width design (i.e., the width is basically the same at all positions along the length). Furthermore, to increase the structural strength of the roof crossbeam, it is often fastened together with the roof outer panel or a specially designed crossbeam outer panel to form a cavity structure.

[0071] However, while the traditional roof beam structure can meet the needs to a certain extent, the cavities formed in the roof beam are generally single-cavity structures, and the width of current vehicle models is getting larger and larger. This makes the structural strength of the traditional roof beam relatively weak, making it difficult to effectively improve the rigidity and modal characteristics of the vehicle roof, which is not conducive to improving the overall quality of the vehicle.

[0072] In view of this, in order to overcome the shortcomings of related technologies, the top cover beam of this embodiment incorporates... Figures 1 to 8 As shown, the overall design includes an upper beam plate 1 and a lower beam plate 2.

[0073] The lower crossbeam 2 has a middle portion 10 and end portions 20 located on the left and right sides, and the width of the middle portion 10 in the front-rear direction of the vehicle is greater than the width of the end portions 20 in the front-rear direction of the vehicle.

[0074] Furthermore, a recessed groove k is formed on the middle portion 10, and raised ribs 201 are provided on the middle portion 10 within the groove k. The raised ribs 201 extend along the left-right direction of the entire vehicle, and there are multiple raised ribs 201 arranged at intervals from front to back. After the upper plate 1 and the lower plate 2 of the crossbeam are connected, the multiple raised ribs 201 divide the groove k into multiple cavities arranged sequentially from front to back.

[0075] Therefore, by making the width of the middle portion 10 on the lower plate 2 of the crossbeam greater than the width of the end portions 20 on both sides, and forming a groove k on the middle portion 10, setting multiple raised ribs 201 located in the groove k, and using the multiple raised ribs 201 to separate multiple cavities arranged sequentially in front and behind, this embodiment can increase the strength of the roof crossbeam structure and improve the rigidity and modality of the vehicle body top by utilizing the synergy between each raised rib 201 and each cavity structure, thereby achieving the effect of improving the overall quality of the vehicle.

[0076] Based on the above overview, specifically, in this embodiment, the top cover beam can be manufactured by stamping, meaning that both the upper beam 1 and the lower beam 2 are specifically stamped sheet metal structures. Furthermore, it is worth noting that, based on the use of stamped sheet metal structures, all kinds of ribs or protrusions provided on the lower beam 2 can also be integrally formed on the lower beam 2 by stamping during its manufacturing process.

[0077] In this embodiment, it remains the same. Figure 2 As shown, the width of the aforementioned middle portion 10 in the longitudinal direction of the vehicle is also... Figure 2 The width m in the middle refers to the width of the two end portions 20 in the longitudinal direction of the vehicle. Figure 2 The width n in the middle. Furthermore, in specific implementation, the width m of the middle part 10 and the width n of the two end parts can be determined according to the strength design requirements of the roof of the vehicle body and the styling design of the roof of the vehicle body, as long as they are easy to manufacture and can meet the corresponding requirements of the vehicle model.

[0078] Furthermore, it is worth noting that in practical implementation, the length of the aforementioned middle portion 10 in the left-right direction of the vehicle can, for example, be much greater than the length of the two end portions 20. This results in a longer middle portion 10, providing more stable support for the outer roof panel or panoramic glass located on the outside (i.e., above) of the roof beam, thus improving the stability of the roof panel or panoramic glass installation. Of course, since the width m of the middle portion 10 is greater than the width n of the two end portions 20, the longer length of the middle portion 10 also helps to better increase the structural strength of the roof beam itself.

[0079] In this embodiment, we continue to combine Figure 6 and Figure 7 As shown, in some exemplary embodiments, based on the stamping of the lower beam plate 2, for example, the front and rear edges of the middle portion 10 may have upwardly convex flanges 211, thereby defining the aforementioned groove k between the two flanges 211.

[0080] Meanwhile, the aforementioned multiple raised ribs 201 specifically include a front raised rib 201a located near the front flange 211, and a rear raised rib 201b located near the rear flange 211. The aforementioned multiple cavities also specifically include a front cavity Q located in front of the front raised rib 201a, a rear cavity S located behind the rear raised rib 201b, and a middle cavity T located between the front raised rib 201a and the rear raised rib 201b.

[0081] At this time, the front and rear sides of the middle part 10 are both flanged 211, and the groove is defined by the flanges 211 on both sides. The protruding ribs include the front protruding rib 201a and the rear protruding rib 201b, and multiple cavities include the front cavity Q, the middle cavity T and the rear cavity S. It can be understood that this not only facilitates the forming of the groove k on the lower plate 2 of the crossbeam, but also facilitates the setting of each protruding rib 201 on the lower plate 2 of the crossbeam, and facilitates the design of multiple cavities.

[0082] Still Figure 3 as well as Figure 6 , Figure 7 As shown, in this embodiment, based on the above-mentioned protruding rib 201 and the structure of each cavity, in some exemplary embodiments, for example, the front cavity Q and the middle cavity T can be connected through the front connecting ports 202 located on the left and right sides of the front protruding rib 201a, while the rear cavity S and the middle cavity T can be connected through the rear connecting ports 203 located on the left and right sides of the rear protruding rib 201b.

[0083] In this way, by connecting the front cavity Q to the middle cavity T through the front connecting ports 202 on both sides of the front protrusion rib 201a, and by connecting the rear cavity S to the middle cavity T through the rear connecting ports 203 on both sides of the rear protrusion rib 201b, it is possible to increase the strength of the roof beam structure by utilizing the cavity structure, and facilitate the flow of electrophoretic liquid between the cavities during the body electrophoresis, thus helping to ensure the electrophoresis effect.

[0084] It is worth noting that, in specific implementation, in addition to connecting the front cavity Q and the middle cavity T through the front connecting port 202, the rear cavity S and the middle cavity T are also connected through the rear connecting port 203. Of course, it is also possible to only connect the front cavity Q and the middle cavity T through the front connecting port 202, or only connect the rear cavity S and the middle cavity T through the rear connecting port 203.

[0085] In addition, in specific implementation, based on the stamping of the lower plate 2 of the crossbeam, the aforementioned front connecting ports 202 located on both sides of the front protruding rib 201a and the rear connecting ports 203 located on both sides of the rear protruding rib 201b are, in other words, during the stamping process, the protruding ribs 201 are not formed at the positions of each front connecting port 202 and each rear connecting port 203, thereby forming a connecting port that can connect the front and rear cavities.

[0086] In this embodiment, the following continues... Figure 3 , Figure 4 as well as Figure 6 and Figure 7 As shown, in some exemplary embodiments, a protrusion 204 located between the front protrusion 201a and the rear protrusion 201b may also be provided on the lower plate 2 of the beam, for example.

[0087] The aforementioned protrusion 204 also extends along the left-right direction of the vehicle, and the protrusion 204 is also spaced apart from the front protrusion 201a and from the rear protrusion 201b.

[0088] At this time, by setting a protrusion 204 between the front protrusion 201a and the rear protrusion 201b, and making the protrusion 204 extend along the left and right direction of the whole vehicle, the structural strength of the lower plate of the crossbeam 2 can be further increased by the protrusion 204, which helps to better increase the overall structural strength and rigidity of the roof crossbeam, and is beneficial to the improvement of the rigidity and modality of the top of the vehicle body.

[0089] Based on the above-mentioned protrusions 204, in some exemplary embodiments of this embodiment, the protrusion height of the protrusions 204 is generally lower than that of the ribs 201. This lower height of the protrusions 204 compared to the ribs 201 avoids excessive stretching of the material of the lower beam plate 2 while forming the protrusions 204, thus preventing adverse effects on the structural performance of the lower beam plate 2.

[0090] Furthermore, in some of the exemplary implementations, see also Figure 2 , Figure 3 and Figure 6 , Figure 7 As shown, for example, the extension length of the protrusion 204 in the left-right direction of the whole vehicle can be greater than that of the rib 201, and both ends of the protrusion 204 are set outward relative to the rib 201.

[0091] Thus, by making the extension length of the protrusion 204 greater than that of each protruding rib 201, and by making both ends of the protrusion 204 set outward relative to the protruding rib 201, this embodiment can use the protrusion 204 to structurally strengthen the lower plate 2 of the crossbeam near both ends. While the protruding rib 204 achieves the main strengthening function, the auxiliary strengthening structure of the protrusion 204 makes the lower plate 2 of the crossbeam have better overall rigidity.

[0092] Furthermore, and more importantly, because the extension length of the protrusion 204 is greater than that of each protruding rib 201, and the two ends of the protrusion 204 are also further outward, therefore, continuing as... Figure 2 , Figure 3 as well as Figure 6 and Figure 7 As shown, the two ends of the protrusion 204 can be located between the front connecting port 202 and the rear connecting port 203, respectively. Thus, in this embodiment, the protrusion 204 can obviously strengthen the positions of the connecting ports where the missing protruding ribs 201 are missing, so as to ensure the structural strength of the lower plate 2 of the crossbeam.

[0093] In some exemplary embodiments of this embodiment, the lower plate 2 of the crossbeam may further be provided with a front connecting rib 205 connecting the protrusion 204 and the front protrusion rib 201a, and a rear connecting rib 206 connecting the protrusion 204 and the rear protrusion rib 201b.

[0094] At this time, by connecting the protrusion 204 and the front protrusion 201a through the front connecting rib 205, and by connecting the protrusion 204 and the rear protrusion 201b through the rear connecting rib 206, it can be understood that the protrusion 204 and each protrusion rib 201 can be effectively connected to form a frame-type rib structure, thereby enabling the protrusion 204 and each protrusion rib 201 to work together better, so as to fully improve the overall structural performance of the lower plate 2 of the crossbeam and the top cover crossbeam.

[0095] In practical implementation, it is worth noting that in addition to providing corresponding connecting ribs between the protrusion 204 and both the front protrusion rib 201a and the rear protrusion rib 201b, it is also feasible to provide a front connecting rib 205 only between the protrusion 204 and the front protrusion rib 201a, or to provide a rear connecting rib 206 only between the protrusion 204 and the rear protrusion rib 201b.

[0096] In addition, in specific implementation, the aforementioned front connecting ribs 205 and rear connecting ribs 206 can usually be configured as multiple ribs spaced apart along the length of the lower plate 2 of the crossbeam to achieve a better connection and reinforcement effect. Meanwhile, the protrusion height of each of the aforementioned connecting ribs can generally be the same as or slightly smaller than the protrusion 204.

[0097] In this embodiment, the following continues... Figure 2 , Figure 3 , Figures 5 to 8 As shown, in some exemplary embodiments, the end portions 20 at both ends may also form recessed grooves e, and after the upper plate 1 and the lower plate 2 of the crossbeam are connected, the grooves e on the end portions 20 at both ends are also formed into cavities G, and the cavities G at both ends are also connected to the cavities formed at the middle portion 10.

[0098] At this time, grooves e are also formed at the end portions 10 at both ends, and cavities G are formed by using grooves e. The formed cavities G are connected to the cavities in the middle portion 10. This not only increases the structural strength at both ends of the roof beam, but also cooperates with the multiple cavities formed in the middle portion 10, so that the roof beam as a whole has good structural strength, which helps to ensure the improvement of the rigidity and modality of the top of the vehicle body. At the same time, it obviously also facilitates the full flow of the electrophoretic liquid between the middle portion 10 and the end portions 20 on both sides during the electrophoresis of the vehicle body, thus ensuring the electrophoresis effect.

[0099] It is worth noting that, in addition to combining Figure 2 , Figure 3 as well as Figure 6 and Figure 7 As shown, the cavities G formed in the end portions 10 at each end can communicate with the cavities formed in the middle portion 10. Of course, in specific implementations, it is also possible for the cavities G at each end to communicate only with a portion of the cavities in the middle portion 10, and this is not a limitation here. Furthermore, the case where the cavities G at each end communicate only with a portion of the cavities in the middle portion 10 can be, for example, by not providing the aforementioned communication ports in the middle portion 10, so that the cavities G communicate only with the middle cavity T.

[0100] In this embodiment, the following continues... Figure 3 as well as Figure 6 and Figure 7 As shown, in some exemplary embodiments, structurally, the lower beam plate 2 may specifically include a lower plate body 21 and connecting plates 22 connected to the left and right sides of the lower plate body 21.

[0101] The lower plate body 21 also has a main body 21a located in the middle and extension ends 21b respectively provided on the left and right sides. The width of the main body 21a in the longitudinal direction of the vehicle is greater than the width of the extension ends 21b on both sides in the longitudinal direction of the vehicle. At the same time, the main body 21a in the lower plate body 21 constitutes the aforementioned middle part 10, and the extension ends 21b on each side are connected to the connecting plate 22 on the same side. Grooves e are formed in both the extension ends 21b and the connecting plate 22, and the extension ends 21b and the connecting plate 22 on the same side together constitute the aforementioned end part 20.

[0102] It is understandable that the lower beam plate 2 is mainly composed of a lower plate body 21 and connecting plates 22 on both sides, and the lower plate body 21 includes a main body 21a and extension ends 21b on both sides, and the main body 21a constitutes the middle part 10, and the extension ends 21b on each side and the connecting plates 22 together constitute the end part 20. This facilitates the design and preparation of the lower beam plate 2, as well as the forming of various ribs or protrusions on the lower beam plate 2, thereby helping to reduce the design and manufacturing cost of the lower beam plate 2.

[0103] Furthermore, the connecting plates 22 on each side can generally be first overlapped with the extension ends 21b at the end of the lower plate body 21, and then fixed together by conventional methods such as welding. In addition to forming the end portion 20 together with the connecting plates 22 via the connected extension ends 21b, in other embodiments, the connecting plates 22 on each side are integrally connected to the lower plate body 21, thus making the entire lower beam plate 2 a single structure.

[0104] In this embodiment, it is worth noting that the above-mentioned upper beam plate 1 can be a specially designed covering structure adapted to the lower beam plate 2, so as to form a relatively independent roof beam together with the lower beam plate 2. Alternatively, the upper beam plate 1 can be made of the outer roof plate covering the top of the vehicle body, that is, the upper beam plate 1 is formed by the part of the outer roof plate corresponding to the lower beam plate 2.

[0105] Taking the upper plate 1 of the crossbeam specifically adapted to the lower plate 2 of the crossbeam as an example, the vehicle using this roof crossbeam could be, for example, a model equipped with a panoramic sunroof, where the roof crossbeam specifically supports the sunroof glass. Furthermore, continuing as... Figure 9 As shown, at this time, from the vertical direction of the whole vehicle, the outline of the upper plate 1 of the crossbeam can generally be set to follow the shape of the lower plate 2 of the crossbeam, and it is also a structure that is wide in the middle and narrow at both ends.

[0106] It is worth noting that, regarding the top cover beam of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still made of... Figures 1 to 9 As shown, it may include, for example, an upper beam plate 1 and a lower beam plate 2 that are fastened together.

[0107] The lower crossbeam plate 2 has a middle portion 10 and end portions 20 located on the left and right sides. The width of the middle portion 10 in the longitudinal direction of the vehicle is greater than the width of the end portions 20 in the longitudinal direction of the vehicle. At the same time, a recessed groove k is formed on the middle portion 10, and a raised rib 201 is also provided in the groove k. The raised rib 201 includes a front raised rib 201a and a rear raised rib 201b. After the upper crossbeam plate 1 and the lower crossbeam plate 2 are connected, the multiple raised ribs 201 divide the groove k into a front cavity Q, a middle cavity T and a rear cavity S arranged sequentially.

[0108] Specifically, the aforementioned trough k is formed by the flanges 211 on the front and rear sides of the lower plate 2 of the crossbeam. The front cavity Q and the rear cavity S are both connected to the middle cavity T. At the same time, a protrusion 204 is also provided between the front protrusion rib 201a and the rear protrusion rib 201b, and the protrusion 204 is connected to the front and rear protrusion ribs 201 through connecting ribs.

[0109] Furthermore, the lower plate 2 of the crossbeam is specifically composed of a lower plate body 21 in the middle and connecting plates 22 on both sides. The lower plate body 21 includes a main body 21b with a larger width and extension ends 21b with a smaller width on both sides. The main body 21b constitutes the middle part 10. The extension ends 201b on each side and the connecting plates 22 together constitute the end part 20. At the same time, each end part 20 also forms a cavity G after the upper and lower plates of the crossbeam are connected by a groove e.

[0110] In the preferred embodiment of the top cover beam above, the specific setting and arrangement of the protruding ribs 201, protruding parts 205, and each connecting rib, connecting plate 22, etc., can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the protruding ribs 201, protruding parts 205, and each connecting rib, connecting plate 22, etc., can also be referred to the description in the above exemplary embodiments.

[0111] The roof beam of this embodiment adopts the above design. By making the width of the middle part 10 on the lower plate 2 of the beam greater than the width of the end parts 20 on both sides, and by setting the middle part 10 with raised ribs 201, and by using multiple raised ribs 201 to separate multiple cavities arranged in sequence, the strength of the roof beam structure can be increased by the cooperation of each raised rib 201 and each cavity structure, thereby improving the rigidity and modality of the vehicle body top and thus improving the overall quality of the vehicle.

[0112] Of course, by utilizing the above-mentioned protruding ribs 201 and the multiple cavities separated by each protruding rib 201, this embodiment can also form a multi-cavity force transmission structure in the roof beam, thereby increasing the roof beam's ability to transmit and disperse collision forces during vehicle collisions, which helps to improve the safety of vehicle collisions and further enhances the overall quality of the vehicle.

[0113] A second aspect of this application provides a vehicle whose roof is provided with a roof beam as described in the first aspect embodiment above.

[0114] In this embodiment, the vehicle, by providing the roof beam as described in the first aspect embodiment above, can increase the structural strength of the roof beam, improve the rigidity and modality of the vehicle body roof, and thus improve the overall quality of the vehicle.

[0115] Furthermore, in some exemplary embodiments of this embodiment, the aforementioned roof beam may be specifically arranged at the center position in the front-rear direction of the vehicle body roof, and further combined with... Figures 10 to 12 As shown, a mounting base 3 can also be provided at the bottom of the top cover crossbeam, for example, for mounting electrical components on the vehicle roof. The mounting base 3 is connected to the lower plate 2 of the crossbeam via several connectors 4, and the connectors 4 are also connected to the location of the cavity.

[0116] It is worth noting that the aforementioned vehicle roof electrical components can be, for example, a ceiling-mounted screen. The aforementioned connectors 4 can be bolts, and multiple bolts can be distributed at different positions on the mounting base 3. To achieve connection with the connectors 4, a connection through hole and a welded nut fixed at the connection through hole can be provided on the lower plate 2 of the crossbeam. Thus, the mounting base 3 is reliably positioned at the bottom of the roof crossbeam by screwing each connector 4 into its corresponding welded nut. To facilitate the connection of the mounting base 3 to the lower plate 2 of the crossbeam, a positioning post 5 can be provided on the mounting base 3, which is then inserted into the positioning hole on the lower plate 2 of the crossbeam during connection.

[0117] In this embodiment, it can be understood that by connecting the mounting base 3 to the lower plate 2 of the crossbeam via the connector 4, and by connecting the connector 4 to the cavity location on the lower plate 2 of the crossbeam, it is not only convenient to realize the connection arrangement of the mounting base 3 on the top cover crossbeam, but also to improve the rigidity of the mounting point of the mounting base 3 by utilizing the large rigidity of the cavity location, thus ensuring the stability of the mounting base 3 installation, and also improving the reliability of the arrangement of electrical components on the vehicle roof.

[0118] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
