Vehicle body structure and vehicle

Abstract

The present disclosure relates to a vehicle body structure and a vehicle. The vehicle body structure comprises a vehicle body main body, a reinforcing frame arranged on the top of the vehicle body main body, and a front cross beam arranged on the front end of the top of the vehicle body main body. The front cross beam comprises a front part and a rear part connected to the rear side of the front part. The rear part is arranged below the reinforcing frame and connected to the bottom of the reinforcing frame. The left and right sides of the rear part are connected to the left and right sides of the vehicle body main body, respectively. Through the above structure design, the rear part of the front cross beam is extended to below the reinforcing frame, and the rear part is connected to the bottom of the reinforcing frame, thereby increasing the stress area between the front cross beam and the reinforcing frame, improving the stress concentration problem, and improving the structural strength of the connection position of the front cross beam and the reinforcing frame. At the same time, the rear part of the front cross beam is connected to the two sides of the vehicle body main body, realizing the connection of the two sides of the reinforcing frame and the sides of the vehicle body, so that the stress on the top of the vehicle body is more effectively transmitted to the sides of the vehicle body, thereby improving the load bearing capacity and the compression resistance of the top of the vehicle body structure.

Description

Technical Field

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

[0002] In the existing vehicle design, a reinforcing frame is installed on the top of the body structure. The design requires the reinforcing frame to have good structural strength, especially for models with a large sunroof (such as a panoramic sunroof) on the top of the body, and models that improve camping function by raising the roof to form a second-level space. These models place higher demands on the structural strength and support capacity of the reinforcing frame.

[0003] However, in the existing vehicle body structure design, the reinforcing frame and skeleton are directly assembled to the front crossbeam via bolts. In this design, the reinforcing frame is only connected to the top of the vehicle body structure, resulting in insufficient connection strength and poor support capacity. Furthermore, when the vehicle top is impacted, the stress concentration at the connection point between the reinforcing frame and the front crossbeam is small, making the connection prone to breakage. Additionally, when the vehicle is driven on bumpy roads, abnormal noises are likely to occur at the front end. Summary of the Invention

[0050] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0051] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] See Figure 1 The illustration represents a partial schematic diagram of the vehicle body structure, specifically showing a portion of the top of the body structure. In this exemplary embodiment, the vehicle body structure proposed in this disclosure is described using a vehicle employing a large-opening, bed-type roof design as an example. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below to apply the relevant designs of this disclosure to other types of vehicles, and these changes will still remain within the scope of the principles of the vehicle body structure proposed in this disclosure.

[0053] like Figure 1 As shown, in one embodiment of this disclosure, the vehicle body structure includes a body body 100, a reinforcing frame 200, and a front crossbeam 300. (See also...) Figures 2 to 6 , Figure 2 The diagram shows a partial plan view of the vehicle body structure, in which the main body 100 is omitted; Figure 3 The middle section represents the way along Figure 1 A sectional view of line AA in the diagram; Figure 4 The middle section represents the way along Figure 1 A sectional view made by line BB in the middle; Figure 5 The diagram shows a partial exploded view of the vehicle body structure, specifically showing the separation of the front crossbeam 300 from the body body and the reinforcing frame 200, while the body body 100 is hidden. Figure 6 The diagram shows a representative exploded view of the front crossbeam 300. The structure, connection methods, and functional relationships of the main components of the vehicle body structure proposed in this disclosure will be described in detail below with reference to the aforementioned figures.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment of this disclosure, the reinforcing frame 200 is disposed on the top of the vehicle body 100, and the front crossbeam 300 is disposed at the front end of the top of the vehicle body 100. The front crossbeam 300 includes a front portion 301 and a rear portion 302 connected to the rear side of the front portion 301. The rear portion 302 of the front crossbeam 300 is located below the reinforcing frame 200 and connected to the bottom of the reinforcing frame 200. That is, this disclosure increases the length of the front crossbeam 300 in the longitudinal direction. The front end of the front crossbeam 300 is adapted to the edge of the vehicle body corresponding to the windshield, and the rear end of the front crossbeam 300 extends to the bottom of the reinforcing frame 200. Furthermore, the left and right sides of the rear portion 302 of the front crossbeam 300 are respectively connected to the left and right sides of the vehicle body 100. Through the above structural design, this disclosure extends the rear portion 302 of the front crossbeam 300 to below the reinforcing frame 200, and uses the rear portion 302 to connect to the bottom of the reinforcing frame 200, increasing the stress-bearing area between the front crossbeam 300 and the reinforcing frame 200, improving stress concentration, and enhancing the structural strength of the connection point between the front crossbeam 300 and the reinforcing frame 200. Simultaneously, this disclosure connects the rear portion 302 of the front crossbeam 300 to both sides of the vehicle body 100, achieving a connection between the sides of the reinforcing frame 200 and the sides of the vehicle body, allowing the stress on the top of the vehicle body to be more effectively transferred to the sides, thus improving the load-bearing capacity and compressive strength of the top of the vehicle body structure.

[0055] like Figures 3 to 6 As shown, in one embodiment of this disclosure, the front crossbeam 300 includes a lower plate 310. The lower plate 310 includes a first part 311 and a second part 312. The first part 311 is a groove structure with the groove facing upward, and the first part 311 is located below the reinforcing frame 200 and connected to the bottom of the reinforcing frame 200. The reinforcing frame 200 closes the groove of the first part 311 and together with the first part 311 forms a first cavity C1. The second part 312 is connected to the front side of the first part 311. Based on this, the left and right ends of the first part 311 are respectively connected to the left and right sides of the vehicle body 100 via two first connectors 330. Through the above structural design, this disclosure provides a cavity structure in the first part 311, and realizes the connection between the left and right ends of the first part 311 and the vehicle body 100 through the cavity structure. This increases the connection area between the first connectors 330 and the first part 311, so that the reinforcing frame 200 can more effectively and fully transmit the force on the top of the vehicle body to the side of the vehicle body, further improving the load-bearing capacity and compressive strength of the top of the vehicle body structure. Meanwhile, since the first part 311 adopts a cavity design, the weight of the components can be reduced while increasing the connection area. In addition, the present disclosure utilizes the reinforcing frame 200 to participate in the cavity structure of the first cavity C1, which helps to reduce the number of components and reduce material costs.

[0056] like Figures 3 to 6As shown, based on the structural design of the first part 311 as a groove structure, in one embodiment of this disclosure, the first part 311 has a first rear groove wall 3111, which participates in forming the first cavity C1 and is located away from the second part 312. Furthermore, a rear flange 3113 can be provided at the top of the first rear groove wall 3111, and the reinforcing frame 200 can connect to this rear flange 3113. Through the above structural design, this disclosure utilizes the rear flange 3113 to connect the first rear groove wall 3111 of the first part 311 to the reinforcing frame 200, ensuring sufficient connection area, guaranteeing connection strength, and reducing assembly difficulty.

[0057] like Figures 3 to 6 As shown, based on the structural design of the first part 311 as a groove structure, in one embodiment of this disclosure, the second part 312 of the front crossbeam 300 can also be a groove structure with the groove opening facing upwards, and the front crossbeam 300 can also include an upper plate 320. The upper plate 320 is disposed above the second part 312 and closes the groove opening of the second part 312, thereby forming a second cavity C2 together with the second part 312. On this basis, the left and right ends of the second part 312 are respectively connected to the left and right sides of the vehicle body 100 via two second connectors 340. Through the above structural design, this disclosure sets a cavity structure in the second part 312, and realizes the connection between the left and right ends of the second part 312 and the vehicle body 100 through the cavity structure, thereby increasing the connection area between the second connector 340 and the second part 312, further improving the connection effect between the front crossbeam 300 and the vehicle body, and further dispersing the force on the top of the vehicle body to the side of the vehicle body. At the same time, since the second part 312 adopts a cavity design, the weight of the components can be reduced while increasing the connection area. In addition, this disclosure utilizes the design of the first cavity C1 and the second cavity C2 to realize the "dual cavity" design of the front crossbeam 300 and the reinforcing frame 200, which is beneficial to improve the rigidity of the components and the rigidity mode of the front end of the vehicle body, and reduce the molding difficulty.

[0058] like Figures 3 to 6 As shown, based on the structural design of the second part 312 as a groove structure, in one embodiment of this disclosure, the second part 312 has a second front groove wall 3121, which participates in forming the second cavity C2 and is located away from the first part 311. Furthermore, a front flange 3123 can be provided at the top of the second front groove wall 3121, and the upper plate 320 can connect to this front flange 3123. Through the above structural design, this disclosure utilizes the front flange 3123 to connect the second front groove wall 3121 of the second part 312 to the upper plate 320, ensuring sufficient connection area, guaranteeing connection strength, and reducing assembly difficulty.

[0059] like Figures 3 to 6As shown, based on the structural design that both the first part 311 and the second part 312 are groove structures, in one embodiment of this disclosure, the first part 311 further has a first front groove wall 3112, which participates in forming the first cavity C1 and is close to the second part 312. Furthermore, the second part 312 also has a second rear groove wall 3122, which participates in forming the second cavity C2 and is close to the first part 311. The first front groove wall 3112 and the second rear groove wall 3122 are arranged at intervals, and the tops of the first front groove wall 3112 and the second rear groove wall 3122 are connected via a connecting part 313. In other words, the lower plate 310 forms a downward-facing groove 314 between its first part 311 and the second part 312. Based on this, the reinforcing frame 200 and the upper plate 320 can be respectively connected to the connecting part 313. Through the above structural design, this disclosure utilizes the connecting part 313 to provide a connection point located between the two cavity structures, further enhancing the connection strength between the front crossbeam 300 and the reinforcing frame 200.

[0060] like Figure 3 and Figure 4 As shown, based on the structural design of the lower plate 310 having a connecting portion 313, in one embodiment of this disclosure, the reinforcing frame 200 and the upper plate 320 are partially stacked, and the overlapping portions of the reinforcing frame 200 and the upper plate 320 are jointly connected to the connecting portion 313 of the lower plate 310. Through the above structural design, this disclosure utilizes the connecting portion 313 to simultaneously connect the reinforcing frame 200 and the upper plate 320, which can reduce the number of connecting structures or components (e.g., mounting holes, bolts, etc. for connection), reduce the structural complexity of components, and simultaneously reduce assembly difficulty and improve assembly efficiency.

[0061] like Figure 3 and Figure 4 As shown, based on the structural design of partially stacked reinforcing frame 200 and upper plate 320, in one embodiment of this disclosure, the stacked portion of upper plate 320 can be located between reinforcing frame 200 and lower plate 310 (i.e., connecting portion 313). Through the above structural design, this disclosure can realize the process steps of "first assembling lower plate 310 and upper plate 320 to form front crossbeam 300, and then assembling front crossbeam 300 with vehicle body and reinforcing frame 200", thereby improving process rationality, reducing process difficulty, and improving production efficiency.

[0062] like Figure 2As shown, based on the structural design of the first part 311 having a first front groove wall 3112 and the second part 312 having a second rear groove wall 3122, in one embodiment of this disclosure, the middle portion of the second rear groove wall 3122 may have a protruding section 31221 facing the first part 311, and the first front groove wall 3112 has a recessed section 31121 corresponding to the protruding section 31221. The term "middle portion" can be understood as any area of ​​the second rear groove wall 3122 other than the left and right ends in the lateral direction of the vehicle body structure, and is not limited to the meaning of the middle position. Through the above structural design, this disclosure can utilize the protruding section 31221 to increase the space of the second cavity C2 at the corresponding position, making it suitable for using the second cavity C2 of the front crossbeam 300 to accommodate other components of the vehicle, such as a lidar, and avoiding interference between the groove wall of the second cavity C2 and these components. Based on this, the present disclosure utilizes the recessed section 31121 corresponding to the protruding section 31221 to avoid the protruding section 31221 from contacting the first front groove wall 3112, that is, to maintain the continuity of the groove 314 formed between the two groove structures.

[0063] like Figure 4 As shown, based on the structural design of the first cavity C1 and the second cavity C2, in one embodiment of this disclosure, along the front-rear direction of the top of the vehicle body 100, the length L1 of the first cavity C1 at both ends is equal to the length L2 of the second cavity C2 at both ends. In other words, at both ends of the front crossbeam 300, the first cavity C1 and the second cavity C2 roughly "evenly divide" the front crossbeam 300 (the term "roughly" means ignoring the length of the groove 314). It should be noted that the so-called "front-rear direction of the top of the vehicle body 100" is not completely consistent with the front-rear direction of the vehicle (i.e., the horizontal longitudinal direction). This is because the front end of the top of the vehicle body may have a certain curvature. Therefore, the aforementioned lengths L1 and L2 refer to the overall structural lengths of the first cavity C1 and the second cavity C2 along the position where the front crossbeam 300 is located on the top of the vehicle body 100. Through the above structural design, this disclosure can further ensure that the force on the top of the vehicle body is more evenly distributed to both sides of the vehicle body.

[0064] It should be noted that the vehicle body structures shown in the accompanying drawings and described in this specification are merely a few examples among many vehicle body structures to which the principles of this disclosure can be employed. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the vehicle body structures shown in the accompanying drawings or described in this specification.

[0065] Based on the above detailed description of several exemplary embodiments of the vehicle body structure proposed in this disclosure, an exemplary embodiment of the vehicle proposed in this disclosure will be described below.

[0066] In one embodiment of this disclosure, the vehicle proposed in this disclosure includes the body structure proposed in this disclosure and described in detail in the above embodiments.

[0067] In one embodiment of this disclosure, the vehicle proposed in this disclosure can be a hybrid vehicle, a non-hybrid vehicle, an electric vehicle, a fuel cell vehicle, or other types of vehicles. The vehicle can be an autonomous vehicle, a semi-autonomous vehicle, or a non-autonomous vehicle.

[0068] It should be noted that the vehicles shown in the accompanying drawings and described in this specification are merely a few examples among many vehicles capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the vehicles shown in the accompanying drawings or described in this specification.

[0069] In summary, the vehicle body structure proposed in this disclosure includes a main body 100, a reinforcing frame 200, and a front crossbeam 300 disposed on the top of the main body 100. The front crossbeam 300 is disposed at the front end of the top of the main body 100. The front crossbeam 300 includes a front portion 301 and a rear portion 302 connected to the rear side of the front portion 301. The rear portion 302 is located below the reinforcing frame 200 and connected to the bottom of the reinforcing frame 200. The left and right sides of the rear portion 302 are respectively connected to the left and right sides of the main body 100. Through the above structural design, this disclosure extends the rear portion 302 of the front crossbeam 300 to below the reinforcing frame 200 and uses the rear portion 302 to connect to the bottom of the reinforcing frame 200, increasing the stress-bearing area between the front crossbeam 300 and the reinforcing frame 200, improving the stress concentration problem, and enhancing the structural strength of the connection position between the front crossbeam 300 and the reinforcing frame 200. Meanwhile, this disclosure connects the rear part 302 of the front crossbeam 300 to both sides of the body body 100, thereby connecting the two sides of the reinforcing frame 200 with the body side, so that the force on the top of the body is more effectively transferred to the body side, improving the load-bearing capacity and compressive strength of the top of the body structure.

For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0076] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
