Description

Technical Field

[0001] The invention belongs to the technical field of automobile manufacturing and relates to a front frame module and a vehicle having the front frame module. Background Art

[0002] Currently, the shift from traditional fuel vehicles to hybrid (or pure electric) vehicles is leading to significant differences in the front-end layout and radiator placement requirements between the two models, requiring significant adjustments to the assembly sequence of front-end components. This leads to low assembly efficiency and poor assembly precision, ultimately resulting in unsatisfactory appearance of the components. The existing radiator assembly is rigidly connected to the front frame or body metal parts using a strong structure and bolts and nuts, without a flexible support structure at the waist. This makes the vehicle prone to resonance and abnormal noise during actual use, resulting in a poor user experience.

[0003] In addition, different models usually need to match different front-end frames during production and manufacturing, but due to differences in models and specific configuration structures (for example: Figure 15-16 As shown, the air intake area of ​​a vehicle's cooling module varies depending on the vehicle's front-end flow field and intake efficiency requirements; the connection and fastening points between the radiator assembly and surrounding components also vary slightly. This, coupled with the rapid iteration of vehicle front-end styling, results in limited product versatility, necessitating continuous investment in R&D. The development process considers numerous factors, including functional and structural compatibility, manufacturing and assembly precision, development cycle, development costs, and parts logistics management. Consequently, the transition from traditional fuel-powered vehicle manufacturers to hybrid or pure electric vehicle manufacturers requires significant investment in both manpower and material resources.

[0004] Therefore, developing a platform-based shared front vehicle frame structure that can meet the mechanical performance requirements in the main structure and the adaptability and stability requirements between components is of great significance to the transformation of automobile manufacturers.

DETAILED DESCRIPTION

[0047] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are implemented based on the above technical solution of the present invention, and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to the following embodiments.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0049] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0050] Example 1:

[0051] like Figure 1 and Figure 2 The front frame of a vehicle shown includes a frame body 1 for fixing a radiator 4 through an inner periphery, a front support member 5 provided on the side wall of the inner periphery of the frame body 1 and used to elastically abut the radiator 4 forward, a side support member 6 provided on the inner periphery of the frame body 1 and used to elastically clamp and fix the radiator 4 from both sides, and a bottom support member 7 provided on the bottom side of the inner periphery of the frame body 1 and used to elastically support the radiator 4; the bottom support member 7 includes a central annular support member 701 and a plurality of support plates 702 radially connected to the outer edge of the central annular support member 701.

[0052] By providing a front-end frame reinforcement support connection structure to the radiator 4, the axial stiffness of the support reinforcement structure at the waist position of the front frame of the vehicle is differentiated, and a flexible waist support connection structure is realized through the elastic support of the front support member 5, the side support member 6, and the bottom support member 7, thereby avoiding resonance and abnormal noise during actual use of the vehicle.

[0053] At the same time, the central annular support member 701 and the plurality of radially arranged support plates 702 form a "spider web" support structure, which supports the structural arrangement with flexibility overcoming rigidity.

[0054] Preferably, Figure 10-11 As shown, the bottom support member 7 is separately assembled at the bottom of the radiator 4, serving as a connecting structure between the frame body 1 and the radiator 4, and further comprises a support pad 703, and a plurality of support ribs 704 arranged in parallel on the support pad 703; a central annular support member 701 and a plurality of support plates 702 are arranged at the bottom of the support pad 703; Figure 12As shown, an opening is provided on the inner bottom side of the frame body 1, and a central annular support member 701 is inserted into the opening, with support ribs 704 abutting against the outer edge of the opening; the support ribs 704 abut against the bottom of the radiator 4. A plurality of support ribs 704 form a support structure with an M-shaped longitudinal section. While cooperating with the "spider web" support structure to have high rigidity in the up and down directions, it also provides a crush function for the entire vehicle in the front and back directions in the event of a collision. More preferably, the M-shaped support structure and the "spider web" support structure are made of elastic materials such as rubber. At the same time, the support ribs 704 are in contact with the bottom of the radiator 4, and can play a heat dissipation role through the grid structure.

[0055] In some specific embodiments, Figure 8-9 As shown, a front support seat 9 is provided on the inner side wall of the frame body 1 , the rear end of the front support member 5 is fixed on the front support seat 9 , and the front end is elastically in contact with the radiator 4 .

[0056] In some specific embodiments, Figure 6-7 As shown, a side support seat 10 with two openings is provided on the inner side wall of the frame body 1 , and the side support member 6 is fixed in the side support seat 10 and extends on both sides, one of which is elastically in contact with the radiator 4 .

[0057] In some specific embodiments, Figure 13-14 As shown, a longitudinal support structure is provided on the side wall of the frame body 1. This longitudinal support structure includes a frame body 11 provided on the side wall of the frame body 1, a diamond-shaped rib 12 provided within the frame body 11, and a plurality of support ribs 13 provided between the frame body 11 and the diamond-shaped rib 12. Support ribs 13 are provided between the upper end of the diamond-shaped rib 12 and the upper wall of the frame body 11, as well as between the upper end and the upper corner of the frame body 11. The two side ends of the diamond-shaped rib 12 are connected to the two side walls of the frame body 11. Support ribs 13 are provided between the lower end of the diamond-shaped rib 12 and the lower wall of the frame body 11, as well as between the lower end and the lower corner of the frame body 11. This longitudinal support structure is applied as a mechanical model of a "bidirectional fork lifter" in the top lock area, which can improve the rigidity of the lock area and enhance NVH performance.

[0058] The above-mentioned front support member 5, side support member 6, bottom support member 7, M-shaped support structure and coordinated "spider web" support structure, as well as the longitudinal support structure, enhance the anti-vibration and anti-noise performance of the front-end heat dissipation module.

[0059] In some specific embodiments, the front support member 5 , the side support member 6 , and the bottom support member 7 are all rubber elastic members.

[0060] In some specific embodiments, the heat sink 4 is a heat dissipation module.

[0061] In some specific embodiments, the front frame further includes an anti-collision beam module 2 and a body beam module 3 detachably connected to the frame body 1. More specifically, the body beam module 3 includes a body cross beam and a body longitudinal beam.

[0062] In some specific embodiments, Figure 4-5 As shown, the frame body 1 and the anti-collision beam module 2 or the body beam module 3 are connected through a bolt structure; the bolt structure includes waist-shaped holes respectively provided on the frame body 1 and the anti-collision beam module 2 or the body beam module 3, a bolt 14 passing through the two waist-shaped holes, and a nut 15 connected to the bolt 14; the bolt 14 and the nut 15 are respectively in contact with the outer edges of the waist-shaped holes on both sides. The relative positions of the connection structures on both sides are adjusted through the waist-shaped holes, and are locked and fixed by the bolts 14 and the nuts 15, thereby realizing the different positions of the radiator mounting points of the fuel version, hybrid version and pure electric version of the car, and meeting the common platform requirements of the front-end module skeleton. Figure 3 As shown, a similar standardized fastening connection structure based on bolts and nuts can also be used for the frame body and the outer body.

[0063] The positioning strategy of the front-end module assembly and the vehicle body in this embodiment is consistent with the tooling positioning strategy during the assembly process, the positioning of the material hanger connected to the vehicle body handling process, and the positioning of the component level itself; all positioning benchmarks are unified, standardized, and platform-based, which reduces errors in process development, improves the manufacturing accuracy of the single-piece size of the front-end frame product, improves the assembly accuracy of the front-end module assembly, and simultaneously realizes the sharing of tooling and fixtures in the production of complete vehicles and components, saving development costs and shortening the development cycle.

[0064] And the front module skeleton is identified by structural design comparison, in order to realize the interchangeable parts of products and mold designs in this difference area for multiple models on the same platform or multiple configurations of the same model; to achieve the purpose of sharing the front module skeleton, such as Figure 3 Section AA\section EE.

[0065] Example 2:

[0066] A car comprises the front frame of the first embodiment.

[0067] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments.
