Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a front cabin structure, a vehicle body, and a vehicle. Background Art

[0002] For vehicles, crash performance, among many other indicators, is a crucial metric for evaluating a vehicle and a reliable guarantee for providing comfort and safety to users. Head-on collisions are a key indicator of vehicle crashworthiness. With the increasing vehicle ownership and improved export performance, higher requirements are being placed on head-on collisions, particularly regarding the amount of intrusion into the driver's cabin during a head-on collision. This places increased demands on the anti-collision structure in the front cabin area, making the optimization of force transmission paths particularly important.

[0003] There are a variety of front cabin structures in the relevant technology, all of which are mature structures. With the improvement of collision requirements, many structural reinforcements have been made. However, they have not achieved the goal of strengthening the anti-collision from the force transmission structure and the overall structure. They are all local reinforcements on the original structure, which cannot achieve an overall improvement effect, and the anti-collision effect is still poor.

[0057] This embodiment provides a front cabin structure and a vehicle body provided with the front cabin structure, and a vehicle provided with the vehicle body. Figure 1 、 Figure 2 and Figure 14 As shown, the front cabin structure may include a front wall panel assembly 2, and A-pillar reinforcement assemblies are respectively provided on the left and right sides of the front wall panel assembly 2 (left and right directions, i.e., Y directions), and the A-pillar reinforcement assembly is fixedly connected to the front wall panel assembly 2, the front wall panel assembly 2 includes a first cavity Q1, and the A-pillar reinforcement assembly includes a second cavity, and the first cavity Q1 is connected to the second cavity.

[0060] In this embodiment, the first cavity Q1 of the front wall panel assembly 2 can provide reliable rigidity for the front wall panel assembly 2. At the same time, the left side of the first cavity Q1 is connected with the A-pillar reinforcement assembly on its left side, and the right side of the first cavity Q1 is connected with the A-pillar reinforcement assembly on its right side, forming a connection between the front cavity and the side cavity. The above structure can become a "backup" for the intrusion amount in a head-on collision, enhance the anti-collision effect of a head-on collision, effectively reduce the intrusion amount of the front cabin structure into the cab during a head-on collision, and better protect the safety of the people in the cab.

[0061] It should be noted that the position of the first cavity Q1 in the vertical direction (ie, the Z direction) can be adjusted according to actual needs and is not limited thereto.

[0062] In an exemplary embodiment, a front cabin structure and a vehicle body provided with the front cabin structure, as well as a vehicle provided with the vehicle body are provided. Figures 1 to 7 as well as Figures 11 to 14 As shown, the front wall panel assembly 2 may include a front wall panel lower section 23, a front wall panel middle section 22, a front wall panel lower section 23, and a front windshield reinforcement 24. The front wall panel lower section 23, the front wall panel middle section 22, the front wall panel lower section 23, and the front windshield reinforcement 24 may be fixedly connected to form the complete front wall panel assembly 2. The fixed connection method may include welding, riveting, screwing, or any other method that satisfies the connection strength, which is not limited to this.

[0063] Among them, the middle end of the front wall panel and the front windshield reinforcement 24 are both left and right through parts, and the two can be fastened and fixedly connected to form a first cavity Q1, which provides good rigidity for the front wall panel assembly 2.

[0064] In addition, in this embodiment, the A-pillar reinforcement assembly may include a front longitudinal beam extension outer panel (shotgun outer panel), an A-pillar outer panel, an A-pillar inner panel and a front longitudinal beam extension inner panel (shotgun inner panel), and the second cavity includes a first sub-cavity and a second sub-cavity, the front longitudinal beam extension outer panel and the front longitudinal beam extension inner panel are buckled together to form the first sub-cavity, the A-pillar outer panel and the A-pillar inner panel are buckled together to form the second sub-cavity, and the first sub-cavity and the second sub-cavity are respectively connected with the first cavity Q1.

[0065] Among them, the A-pillar inner panel includes an A-pillar lower inner panel and an A-pillar upper inner panel, the A-pillar lower inner panel is fixedly connected to the A-pillar upper inner panel, the second sub-cavity includes an upper sub-cavity and a lower sub-cavity that penetrate each other, the A-pillar upper inner panel and the A-pillar outer panel are buckled together to form the upper sub-cavity, and the A-pillar lower inner panel and the A-pillar outer panel are buckled together to form the lower sub-cavity.

[0066] Among them, reference Figures 1 to 7 as well as Figures 11 to 14As shown, the A-pillar reinforcement assembly may also include a door sill, that is, the left A-pillar reinforcement assembly 1b can be formed by the left front longitudinal beam extension outer panel 11b, the left A-pillar outer panel 12b, the left door sill 15b, the left A-pillar lower inner panel 131b, the left A-pillar upper inner panel 132b and the left front longitudinal beam extension inner panel 14b being fixedly connected by welding or screwing; the right A-pillar reinforcement assembly 1a can be formed by the right front longitudinal beam extension outer panel 11a, the right A-pillar outer panel 12a, the right door sill 15a, the right A-pillar lower inner panel 131a, the right A-pillar upper inner panel 132a and the right front longitudinal beam extension inner panel 14a being fixedly connected by welding or screwing.

[0067] In this embodiment, the front cabin structure can be constructed as a bilaterally symmetrical structure, that is, the left A-pillar reinforcement assembly 1b and the right A-pillar reinforcement assembly 1a can be arranged bilaterally symmetrically with respect to the front wall panel assembly 2. Therefore, in this embodiment, at the upper position of the A-pillar (DD cross-section position), the right first sub-cavity Q21a, the right second sub-cavity, and the first cavity Q1 are formed to achieve a connection between the upper right cavities. At the same time, the left first sub-cavity Q21b, the left second sub-cavity Q22b, and the first cavity Q1 achieve a connection between the upper left cavities. Therefore, from left to right, the five cavities, namely the left first sub-cavity Q21b, the left second sub-cavity Q22b, the first cavity Q1, the right second sub-cavity, and the right first sub-cavity Q21a, are connected. This structure can serve as a "backup" for the amount of intrusion in a head-on collision, effectively reducing the amount of intrusion of cabin parts into the cab during a head-on collision.

[0068] In one exemplary embodiment, a front cabin structure, a vehicle body provided with the front cabin structure, and a vehicle provided with the vehicle body are provided. Figures 1 to 15 As shown, in this embodiment, the front cabin structure includes a cabin subassembly 3, which is located in front of the front wall panel assembly 2. The cabin subassembly 3 includes a front cabin integral casting 31, with front shock towers disposed on the left and right sides of the front cabin integral casting 31. Specifically, the cabin subassembly 3 may include the front cabin integral casting 31 and two front shock towers. The front shock tower on the left side of the cabin integral casting 31 is designated as the left front shock tower 32b, and the front shock tower on the right side of the cabin integral casting 31 is designated as the right front shock tower 32a. When the front cabin structure is bilaterally symmetrical, the left front shock tower 32b and the right front shock tower 32a are bilaterally symmetrical about the cabin integral casting 31.

[0069] It should be noted that the front shock tower can also be constructed as a one-piece casting to enhance structural stability. For example, the cabin subassembly 3 can be formed by bolting and FDS connections between the right front shock tower 32a, the front cabin integral casting 31, and the left front shock tower 32b. These three components can all be made of one-piece cast aluminum, and their structure can be equivalent to a cavity structure. Alternatively, these three components can be assembled from sheet metal to form a cavity structure, without limitation.

[0070] The front shock tower is fixedly connected to the front bulge reinforcement assembly, and the rear portion of the front bulge reinforcement assembly is fixedly connected to the front wall assembly 2. That is, the rear portion of the left front shock tower 32b is fixedly connected to the front portion of the left front bulge reinforcement assembly 4b, the rear portion of the left front bulge reinforcement assembly 4b is fixedly connected to the front wall assembly 2, the rear portion of the right front shock tower 32a is fixedly connected to the right front bulge reinforcement assembly 4a, and the rear portion of the right front bulge reinforcement assembly 4a is also fixedly connected to the front wall assembly 2.

[0071] Among them, the front bulge reinforcement assembly includes a third cavity, the front part of which is connected to the cavity of the front shock tower, and the rear part of which is connected to the first cavity Q1. In other words, the left front wheel bulge reinforcement assembly includes a left third cavity Q3b, the front part of which is connected to the cavity of the left front shock tower 32b, and the rear part of which is connected to the left side of the first cavity Q1; similarly, the right front wheel bulge reinforcement assembly includes a right third cavity, the front part of which is connected to the cavity of the right front shock tower 32a, and the rear part of which is connected to the right side of the first cavity Q1. The connection between the three cavities on one side is reflected in the X-direction cavity, which is consistent with the direction of head-on collision. That is, in this embodiment, in addition to the traditional front longitudinal beam absorbing energy, the above-mentioned X-direction cavity can also absorb collision energy very well. At the same time, during a high-speed collision, the front wheel bulge reinforcement assembly can undergo crushing deformation and also absorb collision energy, effectively reducing the amount of intrusion of cabin parts into the cockpit in low-speed and high-speed collisions, and solving the performance problem of head-on collision in the middle stage of the collision.

[0072] In one exemplary embodiment, a front cabin structure, a vehicle body provided with the front cabin structure, and a vehicle provided with the vehicle body are provided. Figures 1 to 15 As shown, in this embodiment, the front shock tower on the same side of the front cabin structure is fixedly connected to the A-pillar reinforcement assembly, and the cavity of the front shock tower on the same side of the front cabin structure is connected to the first sub-cavity of the A-pillar reinforcement assembly. In other words, the left front shock tower 32b is fixedly connected to the left A-pillar reinforcement assembly 1b, and the cavity of the left front shock tower 32b is connected to the left first sub-cavity Q21b of the left A-pillar reinforcement assembly 1b; the right front shock tower 32a is fixedly connected to the right A-pillar reinforcement assembly 1a, and the cavity of the right front shock tower 32a is connected to the right first sub-cavity Q21a of the right A-pillar reinforcement assembly 1a. This embodiment forms a stable front joint on the outside of the cabin through the connection between these cavities.

[0073] The front cabin integral casting 31 is fixedly connected to the A-pillar reinforcement assembly, and its cavity is interconnected with the second sub-cavity. Specifically, the front cabin integral casting 31 is fixedly connected to the left A-pillar reinforcement assembly 1b, and its cavity is interconnected with the left second sub-cavity Q22b. The front cabin integral casting 31 is also fixedly connected to the right A-pillar reinforcement assembly 1a, and its cavity is also interconnected with the right second sub-cavity. This interconnected cavity structure in this embodiment forms a stable lower A-pillar joint.

[0074] In addition, in this embodiment, at the upper portion of the A-pillar (DD section), the left second sub-cavity Q22b, the left first sub-cavity Q21b, and the first cavity Q1 form a left upper cavity connection, and the right second sub-cavity, the right first sub-cavity Q21a, and the first cavity Q1 form a right upper cavity connection. These three cavities on one side are connected together to form a stable upper A-pillar joint. Furthermore, the rear portion of the left third cavity Q3b of the left front wheel bulge reinforcement assembly is connected to the first cavity Q1, and the rear portion of the right third cavity of the right front wheel bulge reinforcement assembly is also connected to the first cavity Q1, thereby forming a rear support joint. The front portion of the left third cavity Q3b of the left front wheel bulge reinforcement assembly is connected to the cavity of the left front shock absorber tower 32b, and the front portion of the right third cavity of the right front wheel bulge reinforcement assembly is connected to the cavity of the right front shock absorber tower 32a, thereby forming a front support joint.

[0075] In this embodiment, by connecting the above-mentioned "double cavity" and "triple cavity", a reinforcement scheme for the joint part of the front cabin structure can be formed, thereby improving the anti-collision effect of the joint part.

[0076] The front wheel bulge reinforcement assembly includes an upper front wheel bulge reinforcement plate and a lower front wheel bulge reinforcement plate, which are fastened together to form the third cavity. Specifically, the left front wheel bulge reinforcement upper plate 41b and the left front wheel bulge reinforcement lower plate 42b are semi-enclosed components, fixedly connected to form the left third cavity Q3b. The right front wheel bulge reinforcement upper plate 41a and the right front wheel bulge reinforcement lower plate 42a are semi-enclosed components, fixedly connected to form the right third cavity.

[0077] In this embodiment, the left A-pillar reinforcement assembly, the cabin sub-assembly 3, the right A-pillar reinforcement assembly, and the front wall panel assembly 2 are penetrated to connect the various cavities to form a complete YZ-plane frame structure. At the same time, the left front wheel bulge reinforcement assembly is connected to the cavity of the left front shock tower 32b, and the right front wheel bulge reinforcement assembly is connected to the cavity of the right front shock tower 32a to form an XZ-plane frame structure. The YZ-plane frame structure is connected to the XZ-plane frame structure to form a complete 3D annular frame structure, which is fixedly connected by welding or screwing to obtain a frame-type front cabin structure. This front cabin structure can be applied to various passenger cars.

[0078] Among them, for the lower area of the front cabin structure, at the lower position of the A-pillar (CC section position), the right side lower cavity is penetrated by the right side second sub-cavity and the front cabin integrated casting 31, and at the same time, the left side lower cavity is penetrated by the left side second sub-cavity Q22b and the front cabin integrated casting 31, so the penetration of the three cavities of the left side second sub-cavity Q22b, the front cabin integrated casting 31 and the right side second sub-cavity is realized from left to right.

[0079] In the front area of the front nacelle structure, the right front shock tower 32a connects with the right first sub-cavity Q21a, achieving a connection between the right side of the front area. The left front shock tower 32b connects with the left first sub-cavity Q21b, achieving a connection between the left side of the front area. Thus, from left to right, the left first sub-cavity Q21b, the nacelle subassembly 3, and the right first sub-cavity Q21a are connected.

[0080] For the middle area of the front structure, the left side of the first cavity Q1, the left third cavity Q3b and the cavity of the left front shock-absorbing tower 32b are connected to achieve the connection of the left middle cavity; the right side of the first cavity Q1, the right third cavity and the cavity of the right front shock-absorbing tower 32a are connected to achieve the connection of the right middle cavity.

[0081] In this embodiment, through the mutual penetration of the above-mentioned various cavities, the interconnection of all cavities such as the first cavity Q1, the right first sub-cavity Q21a, the left first sub-cavity Q21b, the right second sub-cavity, the left second sub-cavity Q22b, the right third cavity and the left third cavity Q3b can be achieved, and the right A-pillar reinforcement assembly, the front wall panel assembly 2, the left A-pillar reinforcement assembly, the cabin sub-assembly 3, the left front wheel bulge reinforcement assembly and the right front wheel bulge reinforcement assembly are connected by the cavity penetration, thereby obtaining the frame-type front cabin structure in this embodiment. Compared with the force-transmitting cabin-type sheet connection structure in the related art, the front cabin structure of this embodiment can effectively improve the frontal collision performance and better reduce the amount of cab intrusion.

[0082] In one exemplary embodiment, a front cabin structure, a vehicle body provided with the front cabin structure, and a vehicle provided with the vehicle body are provided. Figure 9 and Figure 10 As shown, in this embodiment, at least one induced deformation hole K is provided on the upper plate of the front bulge reinforcement and / or the lower plate of the front bulge reinforcement. By providing the induced deformation hole K, the front bulge reinforcement can be well induced to deform and collapse to absorb the collision energy, thereby achieving the purpose of reducing the intrusion amount.

[0083] It should be noted that the number and shape of the deformation-inducing holes K are not limited and can be set according to actual needs. For example, the shape of the deformation-inducing holes K can be circular, square, polygonal, or irregular. The number of deformation-inducing holes K can be one, two, or more. When more than one deformation-inducing hole K is provided, the arrangement of the deformation-inducing holes K is also not limited and can be set according to actual needs. Moreover, the shapes of different deformation-inducing holes K can be the same or different, and this is not limited.

[0084] For example, the upper plate of the front bulge reinforcement may include four deformation-inducing holes K (refer to Figure 9 The four induced deformation holes K on the upper plate of the front bulge reinforcement can be connected at the center of the four induced deformation holes K, and the center lines of the four induced deformation holes K on the lower plate of the front bulge reinforcement can also form a quadrilateral. Similarly, the lower plate of the front bulge reinforcement can also include four induced deformation holes K, and the center lines of the four induced deformation holes K on the lower plate of the front bulge reinforcement can also form a quadrilateral. Due to the instability of the quadrilateral, when a rapid collision occurs in the front cabin structure, the upper plate and the lower plate of the front bulge reinforcement are prone to "instability" due to the arrangement of the above-mentioned induced deformation holes K, inducing the deformation and collapse of the front bulge reinforcement assembly to absorb the collision energy, thereby achieving the purpose of reducing the intrusion amount.

[0085] It should be noted that the deformation-inducing holes K of the left front bulge reinforcement assembly 4b and the right front bulge reinforcement assembly 4a can be the same or different, and this is not limited to this. When the current cabin structure is bilaterally symmetrical, the deformation-inducing holes K of the left front bulge reinforcement assembly 4b are the same as the deformation-inducing holes K of the right front bulge reinforcement assembly 4a.

[0086] In this embodiment, by providing an induced deformation hole K on the front bulge reinforcement assembly, the front bulge reinforcement assembly can be induced to deform and collapse when a rapid collision occurs in the front cabin structure to absorb the collision energy, thereby achieving the purpose of reducing the intrusion amount.

[0087] In the present disclosure, the structural designs such as the frame structure arrangement, joint cavity penetration reinforcement, and induced deformation provide effective energy absorption and support for the middle and final sections of the front cabin structure during a head-on collision, reducing the amount of intrusion of cabin parts into the cab during a collision, and providing a new solution for achieving collision performance in cabin design.
