Abstract
Description
Technical Field
[0001] This application relates to the technical field of vehicle manufacturing, and in particular to an integrated front body, frame, and vehicle. Background Technology
[0002] With the development of vehicle manufacturing technology, the requirements for the structural strength of vehicle bodies are gradually increasing. In related technologies, the body-in-white and suspension structure of heavy commercial vehicles are both independent structures. That is, the front suspension is divided into upper and lower structures. The upper structure of the front suspension is generally made of cast aluminum, which is heavy and is fixed to the body-in-white with bolts.
[0003] The front of a body-in-white typically includes structures such as the front bulkhead inner panel, front floor, front longitudinal beam, A-pillar inner panel, and floor side beam. These are formed by stamping and welding steel sheets to create the body-in-white welded assembly. The production process involves numerous steps and incurs high mold costs. The front longitudinal beam section of the body-in-white is designed with mounting holes for securing the upper suspension components.
[0004] However, the aforementioned suspension mounts are usually connected to the body-in-white by bolts, typically at two or three points. The local stress at the connection points is high, making them prone to damage. Summary of the Invention
[0005] Therefore, it is necessary to provide an integrated front body, frame, and vehicle to address the problem of high local stress and easy damage at the connection between the suspension superstructure and the body-in-white.
[0006] Firstly, this application provides an integrated front body structure, employing the following technical solution:
[0007] An integrated front body includes a front bulkhead mechanism, a connecting member, and a suspension fixing member. The front bulkhead mechanism includes an upper crossbeam, an inner panel, and a lower crossbeam connected sequentially along a first direction, and a front longitudinal beam extending along a second direction and connected to the lower crossbeam. The upper crossbeam and the lower crossbeam extend along a third direction, respectively. Along the second direction, the inner panel includes a first side and a second side arranged opposite to each other, and the front longitudinal beam is located on the first side. The connecting member is located on the second side and is integrally formed with the upper crossbeam, the inner panel, the lower crossbeam, and the front longitudinal beam. The suspension fixing member extends along the second direction and is used for connecting the suspension structure. Along the first direction, the suspension fixing member is integrally formed on the side of the connecting member facing away from the front longitudinal beam. The first direction, the second direction, and the third direction are perpendicular to each other.
[0008] In one embodiment, the front panel mechanism further includes a front floor assembly and a pair of upright beams. The upright beams extend along the first direction and are respectively disposed on opposite sides of the inner panel along the third direction. The front floor assembly is disposed on the first side and is integrated with the upright beams, the front longitudinal beams, and the lower crossbeams.
[0009] In one embodiment, the front floor assembly includes a front center floor and a pair of front side floors. Along the third direction, the front center floor is located between the pair of front side floors. A front longitudinal beam is provided between the front center floor and either of the front side floors. The front center floor, the front longitudinal beam, and the front side floors are constructed as an integral structure.
[0010] In one embodiment, when viewed along the longitudinal direction of the upper crossbeam, the lower crossbeam, and the vertical beam, the upper crossbeam, the lower crossbeam, and the vertical beam are all constructed with an opening on one side; the integrated front body also includes a plurality of reinforcing ribs, which are respectively connected to the inner walls of the upper crossbeam, the lower crossbeam, and the vertical beam.
[0011] In one embodiment, the reinforcing rib includes multiple support segments, and any two support segments are arranged crosswise.
[0012] In one embodiment, the integrated front body also includes an airbag and a mounting component, the mounting component being integrally formed with the connector and the front bulkhead mechanism, and the airbag being mounted on the second side via the mounting component.
[0013] In one embodiment, the end face of the mounting member facing away from the front bulkhead mechanism is configured as an arc surface, which is adapted to fit the side of the airbag.
[0014] Secondly, this application provides a vehicle frame, which adopts the following technical solution:
[0015] A vehicle frame includes the aforementioned integrated front body, floor longitudinal beam, fastener, and suspension structure. The floor longitudinal beam is inserted into the front longitudinal beam along a second direction. The fastener can pass through the front longitudinal beam and the floor longitudinal beam to fix the floor longitudinal beam to the integrated front body. The suspension structure is connected to the suspension fastener along a first direction.
[0016] In one embodiment, viewed along the second direction, the front longitudinal beam and the floor longitudinal beam are respectively constructed with a "U"-shaped cross-section.
[0017] Thirdly, this application provides a vehicle that adopts the following technical solution:
[0018] A vehicle comprising the aforementioned frame.
[0019] The aforementioned integrated front body connecting component, together with the upper crossbeam, inner panel, lower crossbeam, and front longitudinal beam of the front bulkhead mechanism, forms an integral structure, connecting the various components of the front bulkhead mechanism into a whole. The suspension fixing component is integrally formed on the side of the connecting component away from the front longitudinal beam. When the suspension structure is installed on the suspension fixing component, the stress generated at the connection between the suspension structure and the suspension fixing component will be transmitted to the connecting component through the front longitudinal beam, and then distributed to the upper crossbeam, inner panel, and lower crossbeam of the front bulkhead mechanism by the connecting component, thereby improving the connection reliability at the connection between the suspension structure and the suspension fixing component.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intermediate element.

Wherein, "first direction" can be the height direction of the vehicle body; "second direction" can be the longitudinal direction of the vehicle body; and "third direction" can be the width direction of the vehicle body.
[0033] The existing heavy commercial vehicle body-in-white and suspension structure are all independent structures, that is, the front suspension is divided into upper and lower parts. The upper part of the front suspension is generally made of cast aluminum, which is heavy and is fixed to the body-in-white by bolts.
[0034] The front section of a traditional body-in-white typically includes structures such as the front bulkhead inner panel, front floor, front longitudinal beam, A-pillar inner panel, and floor side beam. These are formed by stamping and welding steel sheets to create the body-in-white welded assembly. The production process involves numerous steps and incurs high mold costs. The front longitudinal beam section of the body-in-white is designed with mounting holes for securing the upper suspension components.
[0035] However, the aforementioned suspension mounts are usually connected to the body-in-white by bolts, typically at two or three points. The local stress at the connection points is high, making them prone to damage. The usual solution is to thicken the plates at the local fixing points and increase the strength of the fixing points by using multi-layer plates, but this results in higher costs and greater weight.
[0036] The following is in conjunction with the appendix Figure 1-5 The embodiments of this application will be described in further detail.
[0037] See Figure 1To address the problem of high local stress and easy damage at the connection between the body-in-white and the suspension structure, one embodiment of this application provides an integrated front body that is applied at the junction of the front bulkhead and the floor of the body-in-white of a heavy commercial vehicle. This junction not only needs to be connected to the suspension structure 10, but also to multiple internal parts such as the instrument panel and steering column. The structure is complex and, as a key location for front collision safety, the structural strength requirements for this structure are high.
[0038] The integrated front body includes a front bulkhead mechanism 1, a connecting member 2, and a suspension fixing member 3. The front bulkhead mechanism 1 includes an upper crossbeam 11, an inner panel 12, a lower crossbeam 13 connected sequentially along a first direction F1, and a front longitudinal beam 14 extending along a second direction F2 and connected to the lower crossbeam 13. Both the upper crossbeam 11 and the lower crossbeam 13 extend along a third direction F3.
[0039] In this embodiment, the upper crossbeam 11, inner panel 12, lower crossbeam 13, and front longitudinal beam 14 are constructed as a single integrated structure using integral casting. This effectively reduces the types of parts required to be manufactured during the body-in-white manufacturing process, thereby reducing the types of molds and lowering mold manufacturing costs, which in turn lowers production costs. Furthermore, the front bulkhead mechanism 1 manufactured using integral casting exhibits significantly improved overall dynamic and static stiffness, while also achieving weight reduction, which is beneficial for realizing a lightweight integrated front body design.
[0040] Combination Figure 2 As shown, along the second direction F2, the inner panel 12 includes a first side and a second side arranged opposite to each other. In this embodiment, the first side is actually the rear end of the integrated front body, and the aforementioned front longitudinal beam 14 is located on the first side. The second side is the front end of the integrated front body, and the aforementioned connecting member 2 is located on the second side.
[0041] Specifically, the connector 2 is configured as a rib-like structure protruding in a direction away from the inner plate 12. The connector 2 includes a first segment extending along the first direction F1 and a second segment extending along the second direction F2. The second segment is integrally cast with the first segment, so that the connector 2 in this embodiment is configured as an “L” shaped structure.
[0042] Along the first direction F1, the first section is integrally formed on the end faces of the upper crossbeam 11, the inner plate 12 and the lower crossbeam 13 in sequence. Along the second direction F2, the second section is integrally formed on the lower end face of the lower crossbeam 13. The connecting part 2 is integrally connected and covers the second side of the front enclosure mechanism 1, which plays a connecting role for the various components of the front enclosure mechanism 1, making the connection between the various components of the front enclosure mechanism 1 tighter and further improving the overall structural strength of the front enclosure mechanism 1.
[0043] Specifically, the suspension fastener 3 also extends along the second direction F2 and is integrally formed along the first direction F1 on the side of the connecting member 2 facing away from the front longitudinal beam 14. In this embodiment, the suspension fastener 3 is also integrally cast to form an integral structure with the aforementioned front enclosure mechanism 1 and connecting member 2.
[0044] In addition, the suspension fastener 3 has a fixing point for connecting the suspension structure 10. During actual assembly, the suspension structure 10 is connected to the fixing point of the suspension fastener 3 along the first direction F1. The stress generated at the fixing point between the suspension structure 10 and the suspension fastener 3 is first transmitted to the connecting member 2 through the front longitudinal beam 14, which is integrated with the suspension fastener 3. Along the first direction F1, the stress is evenly distributed to the upper crossbeam 11, the inner plate 12 and the lower crossbeam 13, so that the stress at the connection between the suspension structure 10 and the suspension fastener 3 is evenly distributed to the entire front enclosure mechanism 1 through the connecting member 2, thereby solving the problem of easy damage at the fixing point and improving the connection reliability of the connection between the suspension structure 10 and the suspension fastener 3.
[0045] Continue reading Figure 1 and Figure 2 In some embodiments, the front bulkhead mechanism 1 further includes a front floor assembly 15 and a pair of upright beams 16. Along a third direction F3, the pair of upright beams 16 are located on opposite sides of the front floor assembly 15 and extend along a first direction F1. The front floor assembly 15 is connected to the lower crossbeam 13 along a second direction F2. The upright beams 16 are integrally formed between the front floor assembly 15 and the upper crossbeam 11, inner panel 12, and lower crossbeam 13, providing support for the upper crossbeam 11, inner panel 12, lower crossbeam 13, and front floor assembly 15 in the first direction F1. In this embodiment, the upright beam 16 may specifically be an A-pillar of the vehicle body.
[0046] Specifically, the front floor assembly 15 is located on the second side. The front floor assembly 15 includes a front center floor 151 and a pair of front side floors 152. Along the third direction F3, the pair of front side floors 152 are located on opposite sides of the front center floor 151. A front longitudinal beam 14 is provided between the front center floor 151 and any adjacent front side floor 152. The front center floor 151, the front longitudinal beam 14 and the front side floors 152 are also constructed into an integral structure by integral casting, thereby further enhancing the structural strength of the integrated front body.
[0047] Combination Figures 1 to 3As shown, in some embodiments, the front floor assembly 15 further includes a front floor side beam 153 and a floor side beam outer plate 154, both of which extend along the second direction F2. Along the third direction F3, the front floor side beam 153 is integrally formed on the side of the aforementioned front side floor 152 away from the front middle floor 151, and the floor side beam outer plate 154 is integrally formed on the side of the front floor side beam 153 away from the front side floor 152. The front floor side beam 153 and the floor side beam outer plate 154 provide lateral support to the front bulkhead mechanism 1, further improving the structural strength of the integrated front body.
[0048] Continue reading Figure 3 In addition, in some other embodiments, the upright beam 16 includes an inner A-pillar panel 161, an A-pillar reinforcing plate 162, and an outer A-pillar panel 163. The inner A-pillar panel 161 serves as the main support, while the A-pillar reinforcing plate 162 and the outer A-pillar panel 163 extend along the first direction F1 and are integrally cast with the inner A-pillar panel 161. This gives the inner A-pillar panel 161 stronger structural strength and thus stronger support, thereby further improving the structural strength of the integrated front body.
[0049] See Figures 1 to 3 In this embodiment of the application, when viewed along the longitudinal direction of the upper crossbeam 11, the lower crossbeam 13, the A-pillar inner panel 161, and the front floor side beam 153, the upper crossbeam 11, the lower crossbeam 13, the A-pillar inner panel 161, and the front floor side beam 153 are all constructed as open beams with an opening 4 on one side. Compared with the cavity beams used in traditional vehicle body structure designs, using open beams with an opening 4 as the beam structure of the vehicle body is more suitable for the one-piece casting manufacturing method.
[0050] Furthermore, in this embodiment, the integrated front body also includes multiple reinforcing ribs 5, which are constructed in an "X" shape to achieve simultaneous support for the beam structure in the first direction F1 and the lateral direction. Specifically, all the reinforcing ribs 5 are divided into several parts, located in the cavities of the upper crossbeam 11, lower crossbeam 13, A-pillar inner panel 161, and front floor side beam 153. The reinforcing ribs 5 are integrally cast into the inner walls of the upper crossbeam 11, lower crossbeam 13, A-pillar inner panel 161, and front floor side beam 153 to support the beam structure, thereby improving the structural strength of the upper crossbeam 11, lower crossbeam 13, A-pillar inner panel 161, and front floor side beam 153.
[0051] See Figure 1 In addition, the traditional front bulkhead structure of the white body is made of thin sheet metal stamping. During a frontal collision, the thin sheet metal has no ability to resist collision deformation. At the same time, since there is only a single thin sheet metal between the collision obstacle and the driver's cab, the collision obstacle is easy to intrude into the interior of the driver's cab, resulting in poor safety.
[0052] Therefore, in order to solve the above problems, the integrated front body in this application embodiment also includes an airbag 6 and a mounting component 7. The mounting component 7 is located on the second side of the inner panel 12 and is integrally cast with the connecting component 2 and the front bulkhead mechanism 1. The airbag 6 is mounted on the second side by means of the mounting component 7.
[0053] With the integrated front body structure designed as described above, since the first section of the connecting member 2 and the airbag 6 are both located on the second side of the inner panel 12 of the front bulkhead 1, during a frontal collision, the collision obstacle will first collide with the airbag 6 and the connecting member 2. The connecting member 2 enhances the overall structural strength of the front bulkhead 1, giving it stronger resistance to deformation, while the airbag 6 acts as a buffer, thereby further improving the collision safety of the integrated front body and ensuring the personal safety of the occupants inside the driver's cab.
[0054] Combination Figure 4 As shown, in some embodiments, the end face of the mounting member 7 facing away from the front enclosure mechanism 1 is constructed as an arc surface 71. The arc surface 71 fits and conforms to the side of the airbag 6, providing support. Compared with the pin-type fixation used in the traditional airbag 6 mounting structure, the mounting member 7 with the arc surface 71 in this embodiment has a larger contact area with the airbag 6, resulting in a more stable fixation. The force exerted on the airbag 6 is evenly distributed to the entire front enclosure mechanism 1 through the mounting member 7 and the connecting member 2, making it less likely to cause strength damage to the connection between the airbag 6 and the front enclosure mechanism 1.
[0055] See Figures 1 to 5 In some embodiments, this application also provides a vehicle frame, which includes a floor longitudinal beam 8, a middle floor body 17, a side floor body 18, a suspension structure 10, and the aforementioned integrated front body. The floor longitudinal beam 8 extends along a second direction F2 and is inserted into the aforementioned front longitudinal beam 14. The vehicle frame also includes a fastener (not shown) for fixing the front longitudinal beam 14 and the floor longitudinal beam 8. After the floor longitudinal beam 8 is inserted into the front longitudinal beam 14 along the second direction F2, the fastener passes through the floor longitudinal beam 8 and the front longitudinal beam 14 and locks in place, thereby completing the detachable connection between the floor longitudinal beam 8 and the integrated front body.
[0056] In this embodiment of the application, when viewed along the second direction F2, both the floor longitudinal beam 8 and the front longitudinal beam 14 are constructed with a "U"-shaped cross section, which facilitates the connection between the floor longitudinal beam 8 and the front longitudinal beam 14.
[0057] Similarly, the middle floor body 17 is connected to the aforementioned front middle floor 151 along the second direction F2, and the side floor body 18 is connected to the aforementioned front side floor 152 along the second direction F2. The middle floor body 17 and the front middle floor 151, and the side floor body 18 and the front side floor 152 are connected by riveting or bolting.
[0058] In addition, the aforementioned suspension fastener 3 has two or three bolt holes at the fixing point. Along the first direction F1, the suspension structure 10 can be connected to the suspension fastener 3 by means of fasteners such as bolts. After assembly, the stress generated at the bolt holes of the suspension structure 10 and the suspension fastener 3 will be evenly distributed to each component of the front bulkhead mechanism 1 by means of the connecting part 2, thereby avoiding stress concentration at the connection between the suspension structure 10 and the suspension fastener 3.
[0059] In some embodiments, this application also provides a vehicle (not shown), specifically a commercial vehicle for carrying goods. The vehicle uses the frame described in any of the above embodiments, which has the advantages of high overall structural strength, light overall weight, high reliability of connections between structures, fewer molds required for manufacturing, and low production cost.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
