Description

Technical Field

[0001] The utility model belongs to the field of automobile parts, and in particular relates to a connection structure of a front end frame assembly and a vehicle body longitudinal beam, and an automobile. Background Art

[0002] A low-integration front-end module only integrates components such as the cooling system and condenser, while a high-integration front-end module also integrates components such as the front bumper, front combination lamp, and engine hood lock, and then is assembled to the vehicle body as a whole. This technology not only improves the assembly accuracy of front-end components, but also shortens the production cycle and plays a great role in the process optimization of the assembly line. The core component of the front-end module is the front-end frame assembly, which is the basis for carrying other components and plays an indispensable role in the front-end module.

[0003] Traditional front-end frame assemblies are generally divided into metal frame assemblies and plastic frame assemblies. Currently, both are integrally structured frames, that is, the upper crossbeam and the front collision crossbeam assembly are integrated together. The front-end frame assembly can be divided into upper and lower parts according to its function: the upper part (i.e., the upper crossbeam) is mainly used for the installation of parts such as the front bumper, front combination lamp, and engine hood lock, which involves the shape and appearance DTS, and the accuracy of the installation points must be ensured; the lower part (i.e., the front collision crossbeam assembly) is mainly used for the installation of parts such as the condenser and radiator, which involves load-bearing, and the strength function of the installation points must be ensured.

[0004] CN209938739U discloses a front-end frame of a split vehicle, a front-end module of the vehicle and a vehicle, including an upper beam, a lower beam and a vertical beam connected between the upper beam and the lower beam, the lower beam and the vertical beam are integrally arranged, and the upper beam and the vertical beam are connected by corresponding insertion of the insertion hole and the insertion tongue. When the vertical beam or the lower beam changes, only the lower part of the frame needs to be remade, and the upper beam can still be used; when the lower part of the frame is damaged, only the lower part of the frame needs to be replaced, reducing the cost of replacing parts; at the same time, the lower part of the frame and the upper beam are independently molded, and because the mold size is reduced, the mold debugging time can be reduced when the mold is adjusted. However, the following problems still exist: (1) The lower beam and the vertical beam (hereinafter referred to as the lower part) are made of plastic, which is expensive; (2) The upper beam (hereinafter referred to as the upper part) is directly connected to the vertical beam by plug-in. The upper part is assembled with the lower part as the reference point, and the lower part is positioned and assembled with a certain reference on the vehicle body end. In addition, the parts of the lower part are relatively large. After being assembled with the vehicle body, the cumulative accuracy deviation of the vehicle body end and the lower part will be magnified to the connection reference point with the upper part, and finally transmitted to the upper part, resulting in the final accuracy of the upper part being difficult to guarantee. The installation point accuracy of the front bumper, front combination lamp, engine hood lock and other parts installed on it is the accumulation of the accuracy of the vehicle body end, the lower part and the upper part. The dimensional chain is very long, which places very high requirements on the reference accuracy of the vehicle body end and the accuracy of the lower part, indirectly resulting in increased costs and longer debugging cycles.

[0008] Preferably, a frame connection through hole penetrating in the X direction is provided at a corner of the front collision beam mounting plate of the front collision beam assembly. A frame mounting hole penetrating in the X direction is provided at a corner of the end plate body. Bolts pass through the frame connection through hole and the frame mounting hole and are screwed with nuts, so that the front collision beam assembly is fixedly connected to the end plate in the X direction.

[0009] Preferably, the end of the upper crossbeam has a sink, and an upper crossbeam connection hole penetrating in the Z direction is provided on the sink. The upper side edge of the connector body is bent and extended in the Y direction to form an installation flange, and an upper crossbeam installation hole penetrating in the Z direction is provided on the installation flange.

[0015] In a second aspect, the automobile described in the utility model includes the connection structure between the front end frame assembly and the vehicle body longitudinal beam.

[0016] Compared with the prior art, the utility model has the following effects:

[0017] (1) According to the different functional requirements of precision and strength, the upper crossbeam is an integrally-molded plastic part. The integrally-molded process ensures the precision of the upper crossbeam itself. The front collision crossbeam assembly is a metal part made of sheet metal welding, which reduces costs and meets basic functional requirements. The smaller structure uses high-cost materials and processes (corresponding to the integrally-molded upper crossbeam), and the larger structure uses low-cost materials and processes (corresponding to the front collision crossbeam assembly being made of sheet metal welding). The combination of plastic parts and metal parts has a good balance between the cost and precision quality of the front-end frame assembly.

[0018] (2) The upper crossbeam is connected to the longitudinal beam of the vehicle body through the upper crossbeam connector, and the front collision crossbeam assembly is connected to the longitudinal beam of the vehicle body through the end plate. The direct assembly of the upper crossbeam and the front collision crossbeam assembly is eliminated, and the connection between the upper crossbeam and the front collision crossbeam assembly is interrupted. The functions of the two beams do not interfere with each other, the dimension chain is shortened, and the influence of the front collision crossbeam assembly on the final accuracy of the upper crossbeam is eliminated. The accuracy is easier to guarantee and the debugging cycle is shortened, thereby saving development costs, meeting the accuracy requirements faster, and shortening the development cycle.

[0019] (3) The upper crossbeam is not strongly connected to the front collision crossbeam assembly. If a collision occurs at the front of the vehicle, the repair cost is lower than that of an integral front-end frame assembly, which can effectively improve product competitiveness.

DETAILED DESCRIPTION

[0028] In order to more thoroughly understand the features and technical contents of the embodiments of the present invention, the implementation of the embodiments of the present invention is described in detail below in conjunction with the accompanying drawings.

The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0030] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0031] It should also be pointed out that the terms "first\second\third" involved in the embodiments of the present utility model are only used to distinguish similar objects and do not represent a specific ordering of the objects.

[0032] like Figures 1 to 7 As shown, the embodiment of the utility model provides a connection structure between a front-end frame assembly and a vehicle body longitudinal beam, including a front-end frame assembly, a vehicle body longitudinal beam 3, an upper cross beam connector 4 and an end plate 5. The vehicle body longitudinal beam 3 is a cavity structure with a "mouth"-shaped cross section formed by welding a longitudinal beam outer plate 31 and a longitudinal beam inner plate 32. The end plate 5 is welded to the front end of the vehicle body longitudinal beam 3, and the upper cross beam connector 4 is welded to the longitudinal beam inner plate 32 and the end plate 5. The front-end frame assembly includes an upper cross beam 1 and a front collision cross beam assembly 2. The upper cross beam 1 is an integrally injection-molded plastic part. The end of the upper cross beam 1 is connected to the upper cross beam connector 4 in the Z direction by bolts. The front collision cross beam assembly 2 is a metal part formed by welding a plurality of stamped sheet metals. The front collision cross beam assembly 2 is connected to the end plate 5 in the X direction by bolts. The upper cross beam 1 is a plastic part with high precision and high unit price, and occupies a relatively small part of the front-end frame assembly. The front collision beam assembly 2 is a metal part with high structural strength, lower precision than plastic parts, lower unit price, and occupies a larger part of the front frame assembly. The upper beam 1 is not directly connected to the front collision beam assembly 2, avoiding the influence of the front collision beam assembly 2 on the final precision of the upper beam 1.

[0033] like Figure 3 As shown, in some embodiments, the end of the upper cross beam 1 has a sink, and the sink is provided with an upper cross beam connecting through hole 11 that penetrates in the Z direction. The upper surface of the end of the upper cross beam 1 is provided with a front combination lamp mounting hole 13, and the front combination lamp mounting hole 13 is used to install the front combination lamp. The upper cross beam 1 is provided with a condenser limiting hole 16 that penetrates in the Z direction near the end, and the condenser limiting hole 16 is used to limit the position of the condenser. The front side of the upper cross beam 1 has a front bumper mounting lug extending forward, and the front bumper mounting lug is provided with a front bumper mounting hole 12 that penetrates in the Z direction, and the front bumper mounting hole 12 is used to install the front bumper. The middle part of the front side of the upper cross beam 1 has a hood lock mounting lug extending forward, and the hood lock mounting lug is provided with a hood lock mounting hole 14 that penetrates in the X direction, and the hood lock mounting hole 14 is used to install the hood lock. The rear side of the upper cross beam 1 has an avoidance gap 15, and the avoidance gap is used to avoid other components and related wiring harnesses.

[0034] like Figure 4 , Figure 5 As shown, in some embodiments, the front collision beam assembly 2 comprises a front collision beam 25, a front collision beam mounting plate 21 and a lower beam 23. The four corners of the front collision beam mounting plate 21 are each provided with a frame connecting through hole 22 penetrating in the X direction, and the lower beam 23 is provided with a condenser mounting hole 24.

[0035] like Figure 6 , Figure 7As shown, in some embodiments, the upper cross beam connector 4 has a connector body 41, the rear side edge of the connector body 41 is bent along the Y direction and then extended along the X direction to form a first welding flange 42, the upper side edge of the connector body 41 is bent and extended along the Y direction to form an installation flange 43, and an upper cross beam installation hole 44 and a first positioning hole 46 that penetrate the Z direction are provided on the installation flange 43, and the rear end of the installation flange 43 has a reinforcing flange 45.

[0036] like Figure 6 , Figure 7 As shown, in some embodiments, the end plate 5 has an end plate body 51, a square hole is opened in the center of the end plate body 51, the edges of the square hole are bent backward and extended to form four second welding flanges 52, the inner side of the end plate body 51 is bent forward and extended to form a third welding flange 53, and a frame mounting hole 54 penetrating in the X direction is opened at each of the four corners of the end plate body 51, and a second positioning hole 55 is opened on the end plate body 51.

[0037] like Figure 6 , Figure 7 As shown, the first welding flange 42 is first welded to the longitudinal beam inner plate 32 in the Y direction, and the connector body 41 is then welded to the third welding flange 53. The four second welding flanges 52 extend into the cavity of the vehicle body longitudinal beam 3 and are welded to the vehicle body longitudinal beam 3 (three of the second welding flanges 52 are first welded to the longitudinal beam inner plate 32, and the remaining second welding flange 52 is then welded to the longitudinal beam outer plate 31), so that the upper cross beam connector 4 and the end plate 5 are welded to the vehicle body longitudinal beam 3.

[0038] like Figure 1 , Figure 2 As shown, during assembly, the upper crossbeam 1 is placed on the upper crossbeam connector 4, the upper crossbeam connection through hole 11 is aligned with the upper crossbeam mounting hole 44, the bolts pass through the upper crossbeam connection through hole 11 and the upper crossbeam mounting hole 44 and are screwed with nuts, so that the upper crossbeam 1 and the upper crossbeam connector 4 are connected together by bolts in the Z direction. The front collision crossbeam mounting plate 21 is aligned with the end plate 5, the four frame connection through holes 22 are aligned with the four frame mounting holes 54, the bolts pass through the frame connection through holes 22 and the frame mounting holes 54 and are screwed with nuts, so that the front collision crossbeam assembly 2 and the end plate 5 are connected together by bolts in the X direction.

[0039] The installation of the front bumper, front combination lamp, and engine hood lock all require very high Z-direction precision. The upper crossbeam 1 adopts an integrated injection molding process, and its own precision is guaranteed at one time. Compared with the precision loss caused by the process of stamping and welding of the metal upper crossbeam, it has better and more stable precision quality. The upper crossbeam 1 is also based on the Z-direction surface (i.e., the installation flange 43) of the upper crossbeam connector 4, and is assembled by bolts passing through the upper crossbeam connection holes 11, the upper crossbeam installation holes 44, and screwing with nuts, so the precision of the installation flange 43 also needs to be guaranteed.

[0040] The front collision beam assembly 2 is based on the X direction of the end plate 5 and is assembled by bolts passing through the frame connection holes 22, the frame mounting holes 54 and nuts. It does not require high accuracy of the vehicle body end and its own accuracy, and mainly guarantees its strength. The use of metal material has the advantages of high strength and low cost.

[0041] The vehicle body longitudinal beam 3 focuses on ensuring the accuracy of the Z-direction surface of the upper cross beam connector 4 and the strength of the X-direction installation point of the end plate 5. First, the Z-direction surface accuracy of the upper cross beam connector 4 is determined by welding the first welding flange 42 with the longitudinal beam inner plate 32 (after the first welding flange 42 is first welded with the longitudinal beam inner plate 32 to determine the accuracy, the connector body 41 is then welded with the third welding flange 53). Since the vehicle reference is on the longitudinal beam inner plate 32, only the first welding flange 42 and the longitudinal beam inner plate 32 need to be welded in one sequence to achieve the final accuracy; in addition, because the first welding flange 42 and the longitudinal beam inner plate 32 are welded in the Y-direction surface, the Z-direction accuracy can be adjusted, and even if the accuracy of the Y-direction surface is deviated, it will not cause the accuracy deviation of the Z-direction surface, thereby achieving the overall controllable accuracy of the Z-direction surface, that is, the Z-direction surface accuracy of the upper cross beam connector 4 can be guaranteed, combined with the Z-direction high accuracy of the upper cross beam 1 itself, the accuracy of the final installation point can be guaranteed. Secondly, the strength of the X-direction mounting point of the front collision beam assembly 2 is determined by the welding strength of the end plate 5 and the longitudinal beam inner plate 32. The welding of the end plate 5 and the longitudinal beam 3 of the vehicle body is carried out by circular welding of four second welding flanges 52 with the longitudinal beam inner plate 32 and the longitudinal beam outer plate 31 to form a force-bearing cavity, thereby meeting the strength requirements of the X-direction mounting point of the vehicle body end.

[0042] The embodiment of the utility model further provides a car, which comprises the connection structure between the front end frame assembly and the longitudinal beam of the vehicle body.

[0043] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
