Description

Technical Field

[0001] This utility model pertains to automobile manufacturing; specifically, it relates to a multi-condition compatible passenger vehicle engine compartment structure. Background Technology

[0002] With the development of the automotive industry, the safety and regulatory compliance of vehicle body structures are receiving increasing attention. Traditional vehicle body structure designs often struggle to simultaneously meet the regulatory requirements of different countries and regions, while also achieving a low-cost body and a high-performance body that meets five-star crash safety standards. Therefore, developing a cabin structure that can expand regulatory compliance and achieve five-star body standards while maintaining a high degree of commonality is of significant practical importance.

[0003] Chinese patent (publication number: 213008368U) discloses a vehicle front compartment frame structure, a vehicle front compartment frame, and a vehicle. The vehicle front compartment frame structure includes a crash beam and energy-absorbing box, a front longitudinal beam, a front upper side beam, a front wheel arch, and a front wheel arch reinforcement beam. The front wheel arch is connected between the front longitudinal beam and the front upper side beam. The front wheel arch reinforcement beam is located at the front of the front wheel arch in the longitudinal direction of the vehicle and is connected between the front longitudinal beam and the front upper side beam. A wheel arch cavity extending between the front longitudinal beam and the front upper side beam is formed between the front wheel arch reinforcement beam and the front wheel arch. However, the vehicle front compartment frame structure has weak crash protection capability and cannot meet the five-star crash protection requirements. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a multi-condition compatible passenger car engine compartment structure with dual-path collision transmission and stronger anti-collision capability. To achieve the above objective, the technical solution adopted by this utility model is as follows: a multi-condition compatible passenger car engine compartment structure, a passenger car engine compartment, wherein a kickdown assembly and a collision beam mounting seat are provided in the passenger car engine compartment, and a first-path anti-collision structure and a second-path anti-collision structure are provided in the passenger car engine compartment.

[0005] The first path anti-collision structure includes a front anti-collision beam, an energy-absorbing box, a front longitudinal beam, a front crossbeam of the front bulkhead, and a central channel body. The front anti-collision beam is mounted on an anti-collision beam mounting base. Energy-absorbing boxes are connected to both ends of one side of the front anti-collision beam. The energy-absorbing boxes are connected to the front longitudinal beam. One end of the front longitudinal beam is connected to the front crossbeam of the front bulkhead. The front crossbeam is connected to the central channel body.

[0006] The second path collision avoidance structure includes a passenger seat, an A-pillar inner panel, and a door crossbeam.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0021] like Figures 1-4 As shown, a multi-condition compatible passenger vehicle engine compartment structure is disclosed. The passenger vehicle engine compartment includes a kickdown assembly 1 and a crash beam mounting bracket. A first-path crash protection structure 3 and a second-path crash protection structure 2 are also provided within the passenger vehicle engine compartment. The crash beam mounting bracket and the front crash beam 301 are used to fix the front crash beam 301. The kickdown assembly 1 integrates the traditional split longitudinal beam rear body, subframe rear mounting bracket, and torsion box into a single stamped component, resulting in a stronger structure and better crash protection. The first-path crash protection structure 3 serves as the main crash protection path and provides straight-line crash protection, meeting regulatory collision requirements. The second-path crash protection structure 2 laterally diverts the collision force. The first-path crash protection structure 3 and the second-path crash protection structure 2 work together to meet the five-star offset collision requirements.

[0022] The first-path anti-collision structure 3 includes a front anti-collision beam 301, an energy-absorbing box 302, a front longitudinal beam 303, a front bulkhead front crossbeam 304, and a central tunnel body 305. The front anti-collision beam 301 is mounted on the anti-collision beam mounting seat 2. Energy-absorbing boxes 302 are connected to both ends of one side of the front anti-collision beam 301. The energy-absorbing boxes 302 are connected to the front longitudinal beam 303. One end of the front longitudinal beam 303 is connected to the front bulkhead front crossbeam 304. The front crossbeam is connected to the central tunnel body 305. The front anti-collision beam 301, mounted on the anti-collision beam mounting seat, is the first line of defense against frontal collisions. The front anti-collision beam 301 absorbs and disperses impact force in the initial stage of a collision, reducing the impact energy on the vehicle body and occupants. The front anti-collision beam 301 is generally made of high-strength aluminum alloy, possessing good rigidity and energy absorption characteristics. The front anti-collision beam 301 and the anti-collision beam mounting seat are fixed by bolts, ensuring that it can stably withstand and transmit impact force during a collision. In a frontal collision, the front bumper beam 301 first contacts the impacting object, absorbing some energy through its deformation and transferring the remaining impact force to the energy-absorbing box 302. The energy-absorbing box 302 is connected to both ends of one side of the front bumper beam 301. During the collision, the energy-absorbing box 302 absorbs a large amount of collision energy through its own crushing deformation. The energy-absorbing box 302 is connected to the front bumper beam 301 and the front longitudinal beam 303 by welding, forming a continuous energy transfer path. The energy-absorbing box 302 transfers the collision energy to the front longitudinal beam 303. One end of the front longitudinal beam 303 is welded to the front bulkhead front crossbeam 304, which is an important load-bearing and force-transmitting component in the vehicle body structure. The front longitudinal beam 303 transfers the collision energy to the front crossbeam 304 of the front bulkhead. The front crossbeam 304 further disperses the collision force to both sides of the vehicle body and the central tunnel body 305, enhancing the overall rigidity and collision resistance of the vehicle body. The central tunnel body 305 disperses the remaining energy. The front end of the central tunnel body 305 is welded to the middle part of the front crossbeam 304 of the front bulkhead to form a solid structural frame. The central tunnel body 305 disperses the remaining energy to meet the regulatory collision requirements.

[0023] The second-path collision avoidance structure 2 includes a passenger seat 201, an A-pillar inner panel 202, and a door beam 203. The passenger seat 201 is connected to the vehicle body, and the A-pillar inner panel 202 is installed on the passenger seat 201. The door beam 203 is located at one end of the A-pillar inner panel 202. By adding the second-path collision avoidance structure 2, the first-path collision avoidance structure 3 and the second-path collision avoidance structure 2 work together to meet the five-star offset collision requirements. In an offset collision, the front anti-collision beam 301 serves as the first point of contact, absorbing the initial collision energy through crumpling deformation. Since the collision point is off-center from the vehicle center, to meet the five-star collision requirements, one end of the passenger seat 201 extends and connects to the front anti-collision beam 301. The front anti-collision beam 301 transfers part of the impact force laterally to the passenger seat 201. The passenger seat 201 can disperse part of the impact force to the side structure of the vehicle body, while also deforming to absorb energy to a certain extent, protecting the safety of the passenger. The passenger seat 201 is fixed to the vehicle body via bolts and other means. The passenger seat 201 transfers collision energy to the A-pillar inner panel 202. The A-pillar inner panel 202 and the door crossbeam 203 together constitute an important side impact protection structure of the vehicle body. In a side collision, the A-pillar inner panel 202 effectively resists impact force, absorbs and disperses collision energy, and protects the occupants. The A-pillar inner panel 202 is connected to the passenger seat 201 and the vehicle body frame by welding, and the door crossbeam 203 is also welded to the A-pillar inner panel 202, forming a robust side protection structure. The A-pillar inner panel 202 transfers collision energy to the door crossbeam 203, which further absorbs the collision energy, effectively improving the performance of the entire collision protection system and enhancing vehicle safety.

[0024] The front longitudinal beam 303 is equipped with a bending guide 306. The front longitudinal beam 303 adopts a three-section bending design to guide the transfer of collision energy, improve the performance of the entire collision avoidance system, and enhance the vehicle's safety performance.

[0025] Kickdown Assembly 1 is a one-piece structure. Kickdown Assembly 1 has an internal thermoformed multi-cavity reinforced structure or CBS composite reinforced structure; and it is equipped with high-strength steel reinforcement components to further improve the performance of the entire collision avoidance system and enhance the vehicle's safety performance.

[0026] A crash beam reinforcement box 4 is installed between the energy-absorbing box 302, the front longitudinal beam 303, and the passenger seat 201. The crash beam reinforcement box 4 enhances the structural strength and rigidity of this area, enabling it to better transmit and disperse impact forces during a collision, preventing local structural failure due to excessive stress. The crash beam reinforcement box 4 is typically connected to the energy-absorbing box 302, the front longitudinal beam 303, and the passenger seat 201 by welding, forming a unified reinforced structure. Under collision conditions, it effectively improves the performance of the entire crash protection system, enhancing vehicle safety.

[0027] A side reinforcement 5 is provided on one side of the front longitudinal beam 303. The side reinforcement 5 is used to enhance the deformation resistance of the front longitudinal beam 303 in a side collision. In the event of a side collision, the front longitudinal beam 303 can transfer part of the impact force to the side reinforcement 5, thereby improving the performance of the entire collision avoidance system and enhancing the vehicle's safety performance.

[0028] The central tunnel 305 is connected to the lower crossbeam 7 of the front bulkhead, and a battery pack mounting beam 6 is provided at one end of the front longitudinal beam 303. The battery pack mounting beam 6 provides a stable mounting base for the electric vehicle's battery pack, ensuring the safety and stability of the battery pack during vehicle operation. The lower crossbeam 7 of the front bulkhead enhances the rigidity and collision resistance of the vehicle's bottom, effectively dispersing the impact force to the bottom structure of the vehicle body during a collision, protecting occupants and important components.

[0029] The anti-collision beam mounting bracket is equipped with multiple modular mounting interfaces for the front anti-collision beam 301. These interfaces, along with pre-installed interfaces for various operating conditions, allow for the replacement of anti-collision beams 301 made of different materials to meet diverse collision requirements. This modular design achieves a high degree of commonality across different vehicle models, reducing R&D and manufacturing costs. The structural design can be adjusted to meet the regulatory requirements of different countries and regions, exhibiting excellent scalability. Optimized structural design and material selection ensure that the vehicle body meets five-star safety standards in collisions. Furthermore, the entire structure utilizes lightweight materials such as high-strength aluminum alloy, reducing vehicle weight and improving fuel economy and handling performance.

[0030] The role and effect of the embodiments

[0031] The first-path anti-collision structure 3 and the second-path anti-collision structure 2 work together to form a three-dimensional protection system. In a frontal collision, the front anti-collision beam 301, energy-absorbing box 302, front longitudinal beam 303, front bulkhead front crossbeam 304, and central tunnel body 305 sequentially absorb and transfer energy to ensure compliance with regulatory collision requirements. In an offset collision, the second-path anti-collision structure 2 effectively diverts the lateral impact force, and the passenger seat 201, A-pillar inner panel 202, and door crossbeam 203 work together to achieve a five-star offset collision standard. Furthermore, the integrated design of the kickdown assembly 1 and its internal reinforcement structure improve collision strength. The modular installation interface of the front anti-collision beam 301 achieves a high degree of commonality between different vehicle models, reducing R&D and manufacturing costs. This structural design can be adjusted according to the regulatory requirements of different countries and regions, exhibiting good scalability.
