DETAILED DESCRIPTION
[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0026] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meanings of "multiple" and "several" are two or more, unless otherwise clearly and specifically defined.
[0027] Please also read Figures 1 to 7The side door ring reinforcement structure provided by the utility model is now described. The side door ring reinforcement structure includes an inner panel assembly 10, a reinforcement panel assembly 20, a first reinforcement component 30 and a second reinforcement component 40; wherein the inner panel assembly 10 and the reinforcement panel assembly 20 are interlocked and combined to form a door ring cavity, and the door ring cavity includes an A-pillar upper section cavity 50 and a B-pillar upper section cavity 60, and the A-pillar upper section cavity 50 extends obliquely from front to rear and communicates with the B-pillar upper section cavity 60; the first reinforcement component 30 is arranged in the A-pillar upper section cavity 50, and divides the A-pillar upper section cavity 50 into multiple cellular cavities; the second reinforcement component 40 is arranged in the B-pillar upper section cavity 60, and divides the B-pillar upper section cavity 60 into multiple cellular cavities.
[0028] It should be explained that in the present embodiment, both the inner panel assembly 10 and the reinforcing plate assembly 20 can be formed by overlapping and welding multiple pieces of sheet metal after being stamped, or can be an integral hot-formed welded part, that is, hot-formed steel plates of different strength grades are first butt-welded into one body, and then stamped as a whole. Taking into account the lightweight index and the strength of the welded structure, the inner panel assembly 10 and the reinforcing plate assembly 20 can preferably be an integral hot-formed welded part. Furthermore, in order to avoid the butt welds of the inner panel assembly 10 and the reinforcing plate assembly 20 being in the same section and affecting the overall structural strength, the butt welds of the inner panel assembly 10 and the reinforcing plate assembly 20 can be staggered.
[0029] It should be noted that at least one of the inner panel assembly 10 and the reinforcing plate assembly 20 has a concave cross-section structure, thereby ensuring that an annular cavity surrounding the door opening, i.e., a door ring cavity, can be formed between the edges of the inner panel assembly 10 and the reinforcing plate assembly 20 after they are interlocked and fixed to each other; further, after the edges of the inner panel assembly 10 and the reinforcing plate assembly 20 are interlocked, they can be fixed by a circle of welds or welds distributed at intervals.
[0030] Specifically, the above-mentioned door ring cavity is divided into an A-pillar upper cavity 50, a B-pillar upper cavity 60, a B-pillar lower cavity, a door sill cavity, and an A-pillar lower cavity based on the structure of the vehicle's A-pillar and B-pillar. The above-mentioned cavities are connected in sequence, and the purpose here is to define the actual position of each cavity. For example, the A-pillar upper cavity 50 is a cavity extending forward and backward above the door opening, and the B-pillar upper cavity 60 refers to the cavity in the upper half of the B-pillar. For the side door ring top pressure performance, the structural strength of the above-mentioned A-pillar upper cavity 50 and the B-pillar upper cavity 60 plays a decisive role.
[0031] It should be understood that the above multicellular cavity can be specifically combined with Figure 3 and Figure 4It is understood that two or more adjacent common-wall cavities can be seen from the cross-sectional structure of the A-pillar upper cavity 50 and the B-pillar upper cavity 60. Specifically, the A-pillar upper cavity 50 is separated by the first reinforcement component 30, and the B-pillar upper cavity 60 is separated by the second reinforcement component 40, so that a single cavity with a larger cross-section is separated into several cavities with smaller cross-sections.
[0032] In this embodiment, the first reinforcement component 30 and the second reinforcement component 40 can specifically be one or more sheet metal parts. The interior of the A-pillar upper cavity 50 forms a multi-cellular cavity by arranging the first reinforcement component 30, and the interior of the B-pillar upper cavity 60 forms a multi-cellular cavity by arranging the second reinforcement component 40. Therefore, compared with the method of simply utilizing the structural strength of the first reinforcement component 30 and the second reinforcement component 40 to improve the top pressure performance, the use of the multi-cellular cavity structure can more significantly improve the structural strength of the A-pillar upper cavity 50 and the B-pillar upper cavity 60, thereby improving the top pressure performance of the side door ring, and the material weight of the first reinforcement component 30 and the second reinforcement component 40 required to achieve the expected top pressure capacity by constructing the multi-cellular cavity structure is relatively small, which is more conducive to achieving the lightweight index of the vehicle body structure.
[0033] Compared with the prior art, the side door ring reinforcement structure provided in the present embodiment has an inner panel assembly 10 and a reinforcement panel assembly 20 which are interlocked to form a door ring cavity. A first reinforcement component 30 is arranged in an A-pillar upper cavity 50 which extends obliquely forward and backward at the top of the door ring cavity, and a second reinforcement component 40 is arranged in a B-pillar upper cavity 60 which is connected to the A-pillar upper cavity 50. Thus, the A-pillar upper cavity 50 and the B-pillar upper cavity 60 are respectively separated into multi-cellular cavities by the first reinforcement component 30 and the second reinforcement component 40. Compared with the method of simply increasing the material thickness and selecting high-strength materials, not only can the structural strength of the top area of the door ring cavity be significantly improved, thereby improving the top pressure performance of the side door ring, but also it is conducive to the lightweight of the vehicle body structure.
[0034] In some embodiments, see Figures 2 to 7 The inner panel assembly 10 includes an A-pillar inner panel upper section 11 and a B-pillar inner panel upper section 12; the reinforcement panel assembly 20 includes an A-pillar reinforcement panel upper section 21, an A-pillar upper joint 22, and a B-pillar reinforcement panel upper section 23, and the A-pillar reinforcement panel upper section 21 and the B-pillar reinforcement panel upper section 23 are connected through the A-pillar upper joint 22; wherein, parts of the A-pillar reinforcement panel upper section 21 and the A-pillar upper joint 22 are jointly buckled on the A-pillar inner panel upper section 11 to form an A-pillar upper section cavity 50; parts of the B-pillar reinforcement panel upper section 23 and the A-pillar upper joint 22 are jointly buckled on the B-pillar inner panel upper section 12 to form a B-pillar upper section cavity 60.
[0035] One side wall of the A-pillar upper section cavity 50 corresponds to the A-pillar inner panel upper section 11, and the other side wall corresponds to the A-pillar reinforcement plate upper section 21 and a portion of the A-pillar upper joint 22. At the same time, one side wall of the B-pillar upper section cavity 60 corresponds to the B-pillar inner panel upper section 12, and the other side wall corresponds to the B-pillar reinforcement plate upper section 23 and a portion of the A-pillar upper joint 22. This enables the staggered distribution of the butt welds on the inner panel assembly 10 and the reinforcement plate assembly 20 to be achieved, thereby improving the overall structural strength.
[0036] As a specific structural form of the A-pillar upper joint 22, please refer to Figure 2 and Figure 7 The A-pillar upper joint 22 includes a first connecting section 221 and a second connecting section 222. The first connecting section 221 extends forward and backward and docks with the rear end of the A-pillar reinforcement plate upper section 21. The second connecting section 222 extends downward from the middle of the first connecting section 221 and docks with the top end of the B-pillar reinforcement plate upper section 23. The first connecting section 221 and the A-pillar reinforcement plate upper section 21 are both buckled on the A-pillar inner panel upper section 11 to form an A-pillar upper section cavity 50. The second connecting section 222 and the B-pillar reinforcement plate upper section 23 are both buckled on the B-pillar inner panel upper section 12 to form a B-pillar upper section cavity 60.
[0037] The first connecting section 221 and the second connecting section 222 form a T-shaped or nearly T-shaped structure. The first connecting section 221 and the upper section 21 of the A-pillar reinforcement plate can form a front-to-rear connection, thereby improving the force transmission effect of a head-on collision. At the same time, the second connecting section 222 can form an upper-lower connection with the upper section 23 of the B-pillar reinforcement plate, thereby improving the top pressure performance of the B-pillar upper section cavity 60.
[0038] As a specific implementation of the first reinforcement component 30, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The first reinforcement component 30 includes an A-pillar inner panel plate 31 and an A-pillar reinforcement plate patch 32; wherein the A-pillar inner panel plate 31 is connected to the outer side of the A-pillar inner panel upper section 11; one end of the A-pillar reinforcement plate patch 32 overlaps the A-pillar reinforcement plate upper section 21, and the other end overlaps the first connecting section 221; a first cell cavity 51 is enclosed between the A-pillar reinforcement plate patch 32 and the A-pillar reinforcement plate upper section 21 and the first connecting section 221; a second cell cavity 52 is enclosed between the A-pillar reinforcement plate patch 32 and the A-pillar inner panel plate 31 or the A-pillar inner panel upper section 11; the second cell cavity 52 and the first cell cavity 51 together form an A-pillar upper section cavity 50.
[0039] A part of the A-pillar reinforcement plate patch 32 is overlapped and fixed to the A-pillar reinforcement plate upper section 21, and the other part is overlapped and fixed to the first connecting section 221. On the one hand, the A-pillar reinforcement plate patch 32 can be used to cover the weld between the A-pillar reinforcement plate upper section 21 and the first connecting section 221, thereby avoiding stress failure of the weld and improving the connection strength. On the other hand, the X-direction force transmission performance can be improved, thereby improving the head-on collision force transmission effect of the A-pillar upper section cavity 50; the A-pillar inner panel sticker 31 reinforces the A-pillar inner panel upper section 11 corresponding to the docking area between the A-pillar reinforcement plate upper section 21 and the first connecting section 221, thereby further improving the head-on collision force transmission effect. On this basis, the A-pillar reinforcement plate patch 32 is used to separate the A-pillar upper section cavity 50 to form a double-cell cavity, thereby promoting the achievement of the vehicle body lightweight index on the basis of improving the top pressure performance of the A-pillar upper section cavity 50.
[0040] Some possible implementations include: Figure 2 and Figure 4 It is understood that the second reinforcement component 40 includes a B-pillar reinforcement plate patch 41, one end of the B-pillar reinforcement plate patch 41 overlaps the second connecting section 222, and the other end overlaps the B-pillar reinforcement plate upper section 23, and the B-pillar reinforcement plate patch 41 and the B-pillar inner plate upper section 12 form a B-pillar upper section cavity 60.
[0041] A portion of the B-pillar reinforcement plate 41 is overlapped and fixed to the B-pillar reinforcement plate upper section 23, and the other portion is overlapped and fixed to the second connecting section 222. On the one hand, the B-pillar reinforcement plate 41 can be used to cover the butt weld between the B-pillar reinforcement plate upper section 23 and the second connecting section 222, thereby avoiding weld stress failure and improving the connection strength. On the other hand, the Z-direction force transmission performance can be improved, thereby improving the top pressure performance of the B-pillar upper section cavity 60.
[0042] It should be noted that see Figure 2 and Figure 4 In this embodiment, the second reinforcement component 40 further includes a B-pillar reinforcement plate patch 42, which is connected to the inner side of the B-pillar reinforcement plate 41, and the B-pillar reinforcement plate patch 42 divides the B-pillar upper cavity 60 into a double cavity.
[0043] The B-pillar reinforcement plate patch 42 is separated and connected to the inner side of the B-pillar reinforcement plate to separate the B-pillar upper cavity 60 into two cavities located on both sides thereof, thereby forming the B-pillar upper cavity 60 into a double cavity, and being able to achieve the expected top pressure improvement effect by utilizing the B-pillar reinforcement plate patch 42 with a smaller thickness, thereby being able to promote the achievement of the vehicle body lightweight index on the basis of improving the top pressure performance of the B-pillar upper cavity 60.
[0044] Specifically, the optional structure of the B-pillar reinforcement plate 42 in this embodiment is as follows: Figure 5 and Figure 7As shown, the B-pillar reinforcement plate patch 42 includes a patch upper section 421, a patch lower section 422, and a connecting pipe 423; wherein, the patch upper section 421 is connected to the connecting area of the first connecting section 221 and the second connecting section 222, and the patch lower section 422 is connected to the B-pillar reinforcement plate 41 and is spaced up and down from the patch upper section 421; one end of the connecting pipe 423 is overlapped and fixed to the patch upper section 421, and the other end is overlapped and fixed to the patch lower section 422.
[0045] The B-pillar reinforcement plate patch 42 is composed of an upper and lower part and connected by a connecting pipe 423. On the one hand, it can reduce the material and weight of the B-pillar reinforcement plate patch 42 and promote the lightweight of the vehicle body. On the other hand, the upper part 421 of the patch can be used to strengthen the connecting area of the first connecting section 221 and the second connecting section 222, and the top pressure of the first connecting section 221 can be transmitted to the lower part 422 of the patch through the connecting pipe 423, thereby improving the top pressure transmission effect.
[0046] Specifically, the connecting pipe fitting 423 may be a thermoformed pipe, and both the upper patch section 421 and the lower patch section 422 are provided with grooves suitable for at least partially embedding the side walls of the connecting pipe fitting 423. The two ends of the connecting pipe fitting 423 are respectively embedded in the corresponding grooves and then welded and fixed, thereby improving the connection strength and reliability.
[0047] It should be understood that in this embodiment, see Figures 1 to 5 The side enclosure door ring reinforcement structure also includes a side enclosure outer panel 70, which is buckled on the outer side of the reinforcement plate assembly 20, and a release cavity 80 is formed between the side enclosure outer panel 70 and the reinforcement plate assembly 20. The side enclosure outer panel 70 is the exposed surface of the vehicle body side enclosure, and the edge of the side enclosure outer panel 70 is overlapped with the edge of the reinforcement plate assembly 20 and fixed by welding, bonding, riveting or screwing, and a release cavity 80 is formed between the side enclosure outer panel 70 and the reinforcement plate assembly 20, so that the release cavity 80 can be used to further form a cell cavity on the outer side of the A-pillar upper section cavity 50 and the B-pillar upper section cavity 60, thereby increasing the number of cell cavities in the A-pillar upper section and the B-pillar upper section area, thereby improving the structural strength of the A-pillar upper section and the B-pillar upper section area, and improving the top pressure performance of the side enclosure door ring.
[0048] It should be noted that, in this embodiment, see Figure 6 and Figure 7The inner panel assembly 10 and the reinforcing panel assembly 20 are both integrally formed hot-formed welded parts, and the welds of the inner panel assembly 10 and the reinforcing panel assembly 20 are staggered with each other. Specifically, the inner panel assembly 10 includes an A-pillar inner panel upper section 11, a B-pillar inner panel upper section 12, a B-pillar inner panel lower section 13, a door sill inner panel 14, and an A-pillar inner panel lower section 15, which are sequentially connected to form a ring; the reinforcement plate assembly 20 includes an A-pillar reinforcement plate upper section 21, an A-pillar upper joint 22, a B-pillar reinforcement plate upper section 23, a B-pillar lower joint 24, a door sill reinforcement plate 25, and an A-pillar reinforcement plate lower section 26, which are sequentially connected to form a ring; wherein, based on the connection between the A-pillar upper joint 22 and the B-pillar lower joint 24, the reinforcement plate assembly 20 enables its respective butt welds and the respective butt welds on the inner panel assembly 10 to be staggered and distributed with each other, thereby avoiding the butt welds on the back panel assembly and the reinforcement plate assembly 20 being in the same section, thereby improving the overall structural strength after the inner panel assembly 10 and the reinforcement plate assembly 20 are connected.
[0049] Based on the same inventive concept, Figures 1 to 7 It is understood that an embodiment of the present application also provides a vehicle, including the above-mentioned side door ring reinforcement structure.
[0050] Compared with the prior art, the vehicle provided in this embodiment adopts the above-mentioned side door ring reinforcement structure, and the inner panel assembly 10 and the reinforcement panel assembly 20 are interlocked to form a door ring cavity. By arranging a first reinforcement component 30 in the A-pillar upper cavity 50 extending forward and backward at the top of the door ring cavity, and arranging a second reinforcement component 40 in the B-pillar upper cavity 60 connected to the A-pillar upper cavity 50, the A-pillar upper cavity 50 and the B-pillar upper cavity 60 are respectively separated into multi-cell cavities by using the first reinforcement component 30 and the second reinforcement component 40. Compared with the method of simply increasing the material thickness and selecting high-strength materials, it can not only significantly improve the structural strength of the top area of the door ring cavity, thereby improving the top pressure performance of the side door ring, but also is conducive to the lightweight of the vehicle body structure.
