Description

[0001] The present application relates to the technical field of vehicle parts, and in particular to a vehicle body frame assembly and a vehicle. Background Art

[0002] With the increasing demand for interior space and overall lightweighting in new energy vehicles, the design of vehicle body frames is gradually moving towards diversification and lightweighting. However, excessive lightweighting can reduce the strength of the body frame, leading to a decrease in overall vehicle performance. For example, if the front shock absorber tower in the body frame lacks rigidity, it can easily deform in a collision, posing a safety hazard to the front shock absorber.

[0003] Currently, in order to improve the structural rigidity and strength of the front shock absorber tower package, two methods are usually adopted. One is to increase the material thickness or bracket to meet the rigidity performance, but it is easy to increase the weight of the vehicle, production costs and occupied space, resulting in a reduction in the space inside the vehicle; the other is to use a cast aluminum structure, but this method requires re-opening the mold, and the material and development costs are relatively high.

[0026] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0027] The Z-axis in the accompanying drawings represents the vertical direction or vertical orientation, that is, the up-down position, with the positive direction of the Z-axis representing the top and the reverse direction of the Z-axis representing the bottom. The X-axis in the accompanying drawings represents the horizontal direction or longitudinal orientation, and is designated as the front-to-back position, with the positive direction of the X-axis representing the front side and the reverse direction of the X-axis representing the back side. The Y-axis in the accompanying drawings represents the left-to-right position or the horizontal position, with the positive direction of the Y-axis representing the left side and the reverse direction of the Y-axis representing the right side. It should also be noted that the aforementioned Z-axis, Y-axis, and X-axis are merely for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting this application.

[0028] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0029] As shown in Figure 1, an embodiment of the present application provides a vehicle body frame assembly, including a front shock absorber tower package 1 and a front panel frame 2, the front panel frame 2 including a front panel upper cross beam 21 and a front windshield lower cross beam 22, the front shock absorber tower package 1 and the front panel upper cross beam 21 are respectively connected to the side of the front windshield lower cross beam 22 facing the interior of the vehicle, and the front shock absorber tower package 1 is respectively connected to both ends of the front panel upper cross beam 21 along the left and right directions of the vehicle.

[0030] It should be noted that the left and right direction of the vehicle is the Y-axis direction in Figure 1, referred to as the left and right direction or horizontal direction. Correspondingly, the front and back direction of the vehicle is the X-axis direction in Figure 1, referred to as the front and back direction or longitudinal direction.

[0031] It should also be noted that the engine compartment of the vehicle is located in front of the lower cross beam 22 of the front windshield, and the cabin of the vehicle (i.e., the interior space of the vehicle) is located in the rear of the lower cross beam 22 of the front windshield. Therefore, the side of the lower cross beam 22 of the front windshield facing the interior of the vehicle is the rear side of the lower cross beam 22 of the front windshield, and correspondingly, the side of the lower cross beam 22 of the front windshield facing the outside of the vehicle is the front side of the lower cross beam 22 of the front windshield.

[0032] Specifically, the front shock absorber tower 1 is a component used to mount the front shock absorber spring. It is typically a semi-enclosed structure with an open lower end. A front shock absorber is typically located at each of the left and right front wheels of the vehicle, so each of the left and right front wheels of the vehicle also has a front shock absorber tower 1. The front dash upper cross member 21 and the front windshield lower cross member 22 are typically arranged horizontally (i.e., along the Y-axis in FIG. 1 ) below the front windshield and located behind the engine compartment. The front upper cross beam 21 is usually connected to the middle position of the rear end of the front windshield lower cross beam 22 by welding, the left front shock absorber tower package 1 is usually connected to the left end of the front upper cross beam 21 and the left side of the rear end of the front windshield lower cross beam 22 (that is, the left rear end of the front windshield lower cross beam 22) by welding, and the right front shock absorber tower package 1 is usually connected to the right end of the front upper cross beam 21 and the right side of the rear end of the front windshield lower cross beam 22 (that is, the right rear end of the front windshield lower cross beam 22) by welding.

[0033] In this embodiment, the left and right ends of the front dash upper crossbeam 21 are connected to the front shock absorber towers 1 on the left and right sides of the vehicle, respectively, so that the front dash upper crossbeam 21 can support the left and right front shock absorber towers 1, and the left and right front shock absorber towers 1 can also support the front dash upper crossbeam 21, thereby improving the rigidity of the front shock absorber towers 1 and the dash frame 2. Simultaneously, by connecting the front shock absorber tower 1 and the front dash upper crossbeam 21 to the side of the front windshield lower crossbeam 22 facing the interior of the vehicle, the front windshield lower crossbeam 22 further supports the front shock absorber tower 1 and the front dash upper crossbeam 21, thereby further improving the rigidity of the front shock absorber tower 1 and the front dash upper crossbeam 21, ensuring that the vehicle body frame assembly meets the required rigidity performance. Compared with traditional technologies, this not only reduces production costs but also reduces vehicle weight. Moreover, the front shock absorber tower package 1 is connected to the side of the front windshield lower cross beam 22 facing the interior of the vehicle, so that the front shock absorber tower package 1 can be arranged in the vehicle. In this way, it is convenient to move the front enclosure panel configured to separate the cabin and the cockpit forward to the front side of the front shock absorber tower package 1 to increase the space inside the vehicle.

[0034] Furthermore, the dash upper cross member 21 and / or the windshield lower cross member 22 have a cavity beam structure. This improves the bending resistance of the dash upper cross member 21 and / or the windshield lower cross member 22, thereby reducing the degree of deformation of the dash upper cross member 21 and / or the windshield lower cross member 22 in the event of a collision and ensuring vehicle interior safety.

[0035] Optionally, in combination with what is shown in FIG2 , the front shock absorber tower package 1 includes a first plate body 11, a second plate body 12 and a third plate body 13, the first plate body 11 is connected to the second plate body 12 and is located above the second plate body 12, and the first plate body 11 is overlapped on the front upper cross beam 21 and the front windshield lower cross beam 22, respectively, the second plate body 12 is connected to the upper end of the third plate body 13, and together with the third plate body 13, it forms a first cavity configured to install a front shock absorber spring.

[0036] Specifically, the first plate 11 is the connecting part of the front shock absorber tower package 1, which is configured to connect the front shock absorber tower package 1 with the front upper cross beam 21 and the front windshield lower cross beam 22. The second plate 12 and the third plate 13 are the main structures of the front shock absorber tower package 1, which are configured to install the front shock absorber spring, wherein the first plate 11 and the second plate 12 are roughly horizontally arranged, and the front end of the first plate 11 overlaps the front windshield lower cross beam 22, the left end / right end of the first plate 11 overlaps the front upper cross beam 21, the third plate 13 is roughly vertically arranged, and the third plate 13 is arranged around the edge of the second plate 12, and together with the second plate 12 encloses a first cavity, and the front shock absorber spring is installed in the first cavity. In one example, the third plate 13 can be a closed annular structure, that is, the third plate 13 is arranged in a full circle around the edge of the second plate 12. In another example, as shown in Figure 2, the third plate 13 can be an annular structure with an opening, that is, the third plate 13 is arranged around part of the edge of the second plate 12. No specific setting is made here, and it can be selected according to needs in actual application.

[0037] In this embodiment, by designing the front shock absorber tower package 1 to be composed of three plates: a first plate 11, a second plate 12, and a third plate 13, not only is the mechanical structure of the front shock absorber tower package 1 simplified, but it also facilitates segmented production and processing of the front shock absorber tower package 1, reducing the difficulty of mold design and improving production efficiency. Furthermore, by overlapping the first plate 11 with the front dash upper cross member 21 and the front windshield lower cross member 22, the connection areas between the front shock absorber tower package 1 and the front dash upper cross member 21 and between the front shock absorber tower package 1 and the front windshield lower cross member 22 are increased, thereby ensuring the stability of the three connections.

[0038] Optionally, as shown in FIG. 2 , the front shock absorber tower package 1 further includes a fourth plate body 14 . The fourth plate body 14 is disposed in the first cavity and encloses the third plate body 13 to form a second cavity.

[0039] In this embodiment, the fourth plate 14 is usually welded to the inner side surface of the third plate 13 (i.e., the side of the third plate 13 facing the first cavity). The fourth plate 14 can be arranged vertically, horizontally, or inclined. In practical applications, it is usually preferred that the fourth plate 14 is arranged vertically to increase the rigidity of the front shock absorber tower package 1 in the vertical direction. The second cavity enclosed by the fourth plate 14 and the third plate 13 is usually a closed cavity, but it can also be a cavity with an opening. In this way, by arranging the fourth plate 14 in the first cavity of the front shock absorber tower package 1, and enclosing the fourth plate 14 and the third plate 13 into the second cavity, the fourth plate 14 can be used to further increase the structural strength and rigidity of the front shock absorber tower package 1. In addition, when the fourth plate 14 and the third plate 13 extend downward to connect to the frame longitudinal beam 31 introduced later, the setting of the fourth plate 14 can also improve the connection strength between the front shock absorber tower package 1 and the frame longitudinal beam 31, and the setting of the second cavity can improve the bending resistance at the connection position between the two.

[0040] Optionally, as shown in Figure 3, the vehicle body frame assembly also includes a front subframe 3, which includes a frame longitudinal beam 31 and a first frame cross beam 32. The first frame cross beam 32 is connected to the frame longitudinal beam 31 at both ends along the left and right directions of the vehicle, and the front shock absorber tower package 1 is connected to the corresponding frame longitudinal beam 31.

[0041] In this embodiment, the front subframe 3 is located below the front shock absorber tower package 1 and the front frame 2, wherein the frame longitudinal beam 31 of the front subframe 3 is longitudinally arranged, and the first frame cross beam 32 is transversely arranged, and is roughly located directly below the front shock absorber tower package 1 and the front frame 2. Moreover, there is a frame longitudinal beam 31 on each of the left and right sides of the vehicle, that is, there are two frame longitudinal beams 31, and the left and right ends of the first frame cross beam 32 are respectively fixedly connected to the two frame longitudinal beams 31 by means of welding, etc., and the lower ends of the third plate 13 and the fourth plate 14 of the left front shock absorber tower package 1 are respectively connected to the frame longitudinal beam 21 on the left, and the lower ends of the third plate 13 and the fourth plate 14 of the right front shock absorber tower package 1 are connected to the frame longitudinal beam 31 on the right. In this way, the left ends of the front panel upper cross beam 21 and the front windshield lower cross beam 22 are connected to the left end of the first frame cross beam 32 through the left front shock absorber tower package 1 and the left frame longitudinal beam 31, and the right ends of the front panel upper cross beam 21 and the front windshield lower cross beam 22 are connected to the right end of the first frame cross beam 32 through the right front shock absorber tower package 1 and the right frame longitudinal beam 31, forming a closed ring structure, that is, the first ring structure represented by the bold solid line frame in Figure 3, thereby improving the structural strength and rigidity of the front end of the body frame assembly and ensuring that the body frame assembly meets the rigidity performance.

[0042] Optionally, as shown in Figure 3, the front subframe 3 further includes a second frame crossbeam 33, the first frame crossbeam 32 and the second frame crossbeam 33 are arranged at intervals along the front-to-rear direction of the vehicle, and the two ends of the second frame crossbeam 33 along the left-to-right direction of the vehicle are respectively connected to the frame longitudinal beam 31.

[0043] In this embodiment, the second frame cross member 33 is also disposed transversely and is typically positioned behind the first frame cross member 32. The left and right ends of the second frame cross member 33 are fixedly connected to the left and right frame longitudinal members 31, respectively, using methods such as bolts. This allows the left ends of the dash upper cross member 21 and the windshield lower cross member 22 to be connected to the left end of the second frame cross member 33 via the left front shock absorber tower 1 and the left frame longitudinal member 31, while the right ends of the dash upper cross member 21 and the windshield lower cross member 22 to be connected to the right end of the second frame cross member 33 via the right front shock absorber tower 1 and the right frame longitudinal member 31, forming a closed ring structure, namely the second ring structure represented by the bold dashed line in FIG3 . This results in the front shock absorber tower 1, dash frame 2, and front subframe 3 forming a double-ring structure, further enhancing the structural strength and rigidity of the front end of the vehicle body frame assembly, thereby further ensuring that the vehicle body frame assembly meets the required rigidity requirements.

[0044] Optionally, in combination with Figures 1 and 4, the vehicle body frame assembly also includes a floor frame 4, which includes a floor diagonal beam 41, a floor cross beam 42 and a center channel longitudinal beam 43. One end of the center channel longitudinal beam 43 along the front-to-rear direction of the vehicle is connected to the middle position of the first frame cross beam 32, and both ends of the center channel longitudinal beam 43 along the left-to-right direction of the vehicle are respectively connected to the floor cross beam 42, and both ends of the floor diagonal beam 41 are respectively connected to the first frame cross beam 32 and the center channel longitudinal beam 43.

[0045] In this embodiment, a floor diagonal beam 41 is typically provided on each side of the central tunnel longitudinal beam 43. Multiple floor cross beams 42 are also typically provided on each side of the central tunnel longitudinal beam 43. For example, FIG4 shows an example of four floor cross beams 42 provided on each side of the central tunnel longitudinal beam 43. The floor frame 4 typically has a bilaterally symmetrical structure, with two floor diagonal beams 41 symmetrically arranged on the left and right sides of the central tunnel longitudinal beam 43, and multiple floor cross beams 42 also symmetrically arranged on the left and right sides of the central tunnel longitudinal beam 43. Furthermore, the ends of the floor diagonal beam 41 are respectively connected to the first frame cross beam 32 and the central tunnel longitudinal beam 43. In other words, the floor diagonal beam 41 is obliquely arranged between the first frame cross beam 32 and the floor cross beam 42 closest to the first frame cross beam 32. For example, when three floor cross beams 42 are provided on each side of the central tunnel longitudinal beam 43, the floor frame 4 generally has a "sheep" shape. In this way, by setting the floor diagonal beam 41 and connecting the two ends of the floor diagonal beam 41 to the first frame cross beam 32 and the middle channel longitudinal beam 43 respectively, the floor diagonal beam 41 and the first frame cross beam 32 and the middle channel longitudinal beam 43 are combined to form a triangular ring structure, that is, the front end of the floor frame 4 and the front subframe 3 are combined to form a closed ring structure, thereby improving the stiffness and strength of the lower half of the body frame assembly (that is, the lower body frame).

[0046] 4 , one end of the floor diagonal beam 41, which is away from the center channel longitudinal beam 43, is connected to the junction of the first frame cross beam 32 and the frame longitudinal beam 31. This improves the rigidity and strength of the connection between the front end of the floor frame 4 and the front subframe 3, ensuring a secure connection between the two.

[0047] Optionally, in combination with Figures 1 and 4, the floor frame 4 also includes a threshold side beam 44, which is arranged corresponding to the frame longitudinal beam 31, and the threshold side beam 44 is connected to the corresponding frame longitudinal beam 31, and the end of the floor cross beam 42 away from the center channel longitudinal beam 43 is connected to the corresponding threshold side beam 44.

[0048] In this embodiment, like the frame longitudinal beams 31, two sill side beams 44 are provided. These two sill side beams 44 are longitudinally arranged and connected to the rear ends of the left and right frame longitudinal beams 31, respectively. Specifically, the floor crossbeam 42 located on the left side of the central tunnel longitudinal beam 43 is connected to the central tunnel longitudinal beam 43 and the left sill side beam 44. Similarly, the floor crossbeam 42 located on the right side of the central tunnel longitudinal beam 43 is connected to the central tunnel longitudinal beam 43 and the right sill side beam 44. Thus, by connecting the floor crossbeams 42 on the left and right sides of the central tunnel longitudinal beam 43 to the corresponding sill side beams 44, the floor crossbeams 42, the central tunnel longitudinal beam 43, and the sill side beams 44 form multiple closed ring structures, such as a "mouth" shape. That is, the floor frame 4 forms multiple closed ring structures on the left and right sides of the central tunnel longitudinal beam 43, thereby improving the rigidity and strength of the lower body frame, thereby reducing the risk of failure of the body frame assembly in the event of a frontal or side collision. In addition, since the auxiliary instrument panel is usually fixed on the center channel longitudinal beam 43 and the seats of the entire vehicle are usually fixed on the floor cross beam 42, after the rigidity of the lower body frame is improved, the auxiliary instrument panel mode and the entire vehicle seat mode can also be improved, reducing the probability of vibration of the auxiliary instrument panel and the entire vehicle seat mode.

[0049] Optionally, in combination with Figures 4 and 5, the threshold side beam 44 includes a first side beam 441 and a second side beam 442, the first side beam 441 is provided with a third cavity 443, the second side beam 442 is connected to the side of the first side beam 441 facing the middle channel longitudinal beam 43, and forms a fourth cavity 444 with the first side beam 441.

[0050] In this embodiment, the first side beam 441 can be a hollow structure, in which case the interior space of the hollow structure is the third cavity 443. The first side beam 441 can also be a semi-enclosed structure with a roughly U-shaped cross-section. In this case, the first side beam 441 itself encloses the third cavity 443. The second side beam 442 is typically welded to the side of the first side beam 441 facing the center channel longitudinal beam 43, i.e., the inner side of the first side beam 441. Moreover, the second side beam 442 and the first side beam 441 together enclose a fourth cavity 444. This gives the sill side beam 44 a dual-cavity beam structure with the third cavity 443 and the fourth cavity 444, improving the rigidity of the sill side beam 44 and further enhancing the rigidity of the floor frame 4 and, ultimately, the vehicle body frame assembly.

[0051] Optionally, in combination with Figures 1 and 6, the floor frame 4 also includes a first reinforcing plate 45 and / or a second reinforcing plate 46, the first reinforcing plate 45 is connected to the middle channel longitudinal beam 43 and extends along the middle channel longitudinal beam 43, and the second reinforcing plate 46 is connected to the floor cross beam 42 and extends along the floor cross beam 42.

[0052] In this embodiment, when the cross-section of the central channel longitudinal beam 43 is a U-shaped structure with the opening facing downward, or similar to a U-shaped structure, the first reinforcing plate 45 is typically disposed at the lower end of the central channel longitudinal beam 43. In this case, the first reinforcing plate 45 and the central channel longitudinal beam 43 form a cavity beam structure. When the cross-section of the central channel longitudinal beam 43 is a U-shaped structure with the opening facing upward, or similar to a U-shaped structure, the first reinforcing plate 45 can also be disposed at the upper end of the central channel longitudinal beam 43. In this case, the first reinforcing plate 45 and the central channel longitudinal beam 43 form a cavity beam structure. Similarly, depending on the specific structure of the floor cross member 42, the second reinforcing plate 46 can also be disposed at the upper or lower end of the floor cross member 42 to ensure that the second reinforcing plate 46 and the floor cross member 42 form a cavity beam structure. Thus, by disposing the first reinforcing plate 45 on the central channel longitudinal beam 43, the rigidity of the floor frame 4 at the central channel longitudinal beam 43 is increased, and by disposing the second reinforcing plate 46 on the floor cross member 42, the rigidity of the floor frame 4 at the floor cross member 42 is increased.

[0053] Another embodiment of the present application provides a vehicle, comprising the vehicle body frame assembly as described above.

[0054] The beneficial effects of the vehicle in this embodiment compared to conventional technology are the same as those of the above-mentioned vehicle body frame assembly and will not be repeated here.

[0055] Although the present application is disclosed as above, the protection scope of the present application is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications will fall within the protection scope of the present application.
