Automobile front-end anti-collision energy-absorbing structure and automobile thereof

Abstract

This invention provides a front-end collision protection and energy-absorbing structure for automobiles and the corresponding automobile. The collision protection and energy-absorbing structure is installed in the front compartment of the automobile and includes: a front bumper beam assembly for front-end collision protection; a shotgun assembly for enhancing side strength; and a secondary bumper beam assembly, including a secondary bumper beam and an energy-absorbing box. The secondary bumper beam has a first connector connecting it to the front bumper beam, and the energy-absorbing box has a second connector connecting it to the shotgun assembly. The secondary bumper beam is positioned above the front bumper beam to reduce deformation of the passenger compartment during a collision. The secondary bumper beam is connected to the front bumper beam assembly via the first connector, thus distributing the impact force on the front of the automobile, increasing initial energy absorption, and reducing passenger compartment deformation. Furthermore, because the secondary bumper beam assembly is located in the front compartment of the automobile, it increases energy absorption at the front of the vehicle, thereby reducing the energy absorption requirements at the rear of the engine compartment and achieving overall vehicle weight reduction.

Description

Technical Field

[0001] This invention relates to the automotive field, and in particular to a collision-resistant energy-absorbing structure for the front end of a vehicle and the vehicle thereof. Background Technology

[0002] Existing front-end collision avoidance structures such as Figure 1 As shown, the Shotgun assembly is directly connected to the longitudinal beam and absorbs energy through the connection between the front bumper beam assembly and the longitudinal beam. Therefore, when the front of the car is hit by a collision, the bottom torque is transmitted sequentially from the front bumper beam, the energy absorption box, and the longitudinal beam; while the top torque is directly borne by the Shotgun assembly and then transmitted to the A-pillar of the car; for side impacts, the torque is first absorbed by the lower sub-bumper beam and then finally transmitted to the subframe of the car.

[0003] In current car designs, some cars do not have a subframe. When the front of the car is hit, the torque on the top is directly borne by the shotgun assembly. Since the shotgun assembly does not have energy absorption characteristics, the impact torque will cause the shotgun assembly to twist and squeeze into the passenger compartment, ultimately squeezing the legs of the occupants and threatening their safety.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] This invention provides a collision avoidance and energy absorption structure for the front end of a car and the car thereof, in order to solve the technical problems mentioned in the background art.

[0006] The first aspect of this invention provides a collision-resistant energy-absorbing structure for the front end of a vehicle, disposed within the front compartment of the vehicle, the collision-resistant energy-absorbing structure comprising:

[0007] Front bumper beam assembly, used for front-end collision protection in automobiles;

[0008] Shotgun assembly, used to improve the side strength of a car;

[0009] And the secondary bumper beam assembly, including the secondary bumper beam and the energy-absorbing box;

[0010] The sub-collision beam is equipped with a first connector that connects to the front collision beam, and the energy-absorbing box is equipped with a second connector that connects to the shotgun assembly. The sub-collision beam is located above the front collision beam and is used to reduce the deformation of the passenger compartment during a car collision.

[0011] Understandably, the "Shotgun assembly" in this application refers to the longitudinal beam that mounts the front fender on the vehicle, located on the outermost side of the engine compartment. The anti-collision beam is a device used to absorb collision energy when a vehicle is involved in a collision. It consists of a main beam, an energy-absorbing box, and a mounting plate connecting to the vehicle. Both the main beam and the energy-absorbing box can effectively absorb collision energy during low-speed collisions, minimizing damage to the vehicle's longitudinal beams and thus protecting the vehicle. The front anti-collision beam assembly refers to the anti-collision mechanism installed in the front engine compartment and connected to the longitudinal beam. The secondary anti-collision beam assembly refers to an additional component installed in the front engine compartment for energy absorption. The energy-absorbing box and the front anti-collision energy-absorbing box refer to automotive components that can collapse and absorb energy during a collision, improving vehicle safety. In the X, Y, and Z directions mentioned in this document, the X direction refers to the longitudinal direction of the vehicle, the Y direction refers to the lateral direction, and the Z direction refers to the vertical direction. The A-pillar is the connecting pillar between the roof and the front compartment on the left and right front sides.

[0012] In this solution, by installing a secondary anti-collision beam assembly between the original front anti-collision beam assembly and the shotgun assembly, the deformation of the upper part of the front compartment during a car collision can be effectively reduced. After the secondary anti-collision beam is impacted, the energy-absorbing box installed on the secondary anti-collision beam can absorb part of the impact force. Only then will the impact force be transmitted to the shotgun assembly through the second connector, thus protecting the occupant's thighs. The secondary anti-collision beam is connected to the front anti-collision beam assembly through the first connector, and at the same time, it distributes the impact force on the front of the car, which can increase the initial energy absorption and reduce the deformation of the passenger compartment. At the same time, since the secondary anti-collision beam assembly is located in the front compartment of the car, it increases the energy absorption of the front of the car, thus reducing the energy absorption requirement of the rear of the engine compartment, thereby achieving the goal of overall vehicle weight reduction.

[0013] In a further embodiment of the present invention, the front bumper beam assembly includes:

[0014] Front bumper beam and front bumper beam energy absorption box;

[0015] The front bumper beam energy-absorbing box is used to connect with the longitudinal beams of the vehicle.

[0016] In this solution, by setting the front bumper beam assembly as a front bumper beam and a front bumper beam energy absorption box, the energy absorption of the front of the car can be effectively improved. When the car is hit by a collision, the front bumper beam will transfer the impact force to the front bumper beam energy absorption box. After the energy absorption box absorbs part of the impact force, it will be transferred to the chassis through the longitudinal beam, thereby improving the energy absorption of the car when it is hit by a collision and preventing damage to the car chassis.

[0017] In a further embodiment of the present invention, both the front bumper beam and the secondary bumper beam are arc-shaped, and the arc of the front bumper beam and the secondary bumper beam are the same.

[0018] In this design, by making both the front bumper beam and the secondary bumper beam curved, the impact force transmitted from all directions during a car collision can be absorbed. At the same time, by making the curvature of the front bumper beam and the secondary bumper beam the same, the front bumper beam and the secondary bumper beam can transmit the impact force received by the car simultaneously. Then, the energy is absorbed by the energy-absorbing box and the energy-absorbing box of the front bumper beam, thereby effectively reducing the deformation of the passenger compartment and improving the protective effect of the structure.

[0019] In a further embodiment of the present invention, the second connector includes a second connecting plate and a connecting bolt. The second connecting plate is provided with four connecting holes, and the shotgun assembly is provided with four mating threaded holes that mate with the connecting holes. The connecting bolt passes through the connecting holes and is threadedly connected to the mating threaded holes.

[0020] In this design, the second connector is set as a connecting plate, which is generally square. Each of the four corners of the connecting plate has a connecting hole. The Shotgun assembly has threaded holes that mate with the four connecting holes. Connecting bolts pass through the connecting holes and are threaded into the threaded holes, thus connecting the second connecting plate to the Shotgun assembly. Since the second connecting plate is set on the energy-absorbing box, the sub-bumper beam assembly and the Shotgun assembly are connected. The threaded connection facilitates the assembly and connection of the sub-bumper beam assembly and the Shotgun assembly, improving installation efficiency.

[0021] In a further embodiment of the present invention, two energy-absorbing boxes and two front anti-collision beam energy-absorbing boxes are provided, with the two energy-absorbing boxes symmetrically arranged on the secondary anti-collision beam and the two front anti-collision beam energy-absorbing boxes symmetrically arranged on the front anti-collision beam.

[0022] In this solution, by setting two energy-absorbing boxes, the impact force received by the secondary anti-collision beam can be evenly absorbed by the energy-absorbing boxes on both sides when the car is hit, which improves the energy absorption effect and protects the shotgun assemblies on both sides of the car. Similarly, the energy-absorbing box of the front anti-collision beam can also effectively absorb the impact force from both sides, thereby effectively protecting the longitudinal beams in the car.

[0023] In a further embodiment of the present invention, two first connectors are provided, the two first connectors are symmetrically arranged, one end of the two first connectors is disposed between the two front anti-collision beam energy absorption boxes, and the other end is disposed between the two energy absorption boxes.

[0024] In this solution, by placing two first connectors between the two front bumper beam energy-absorbing boxes, when the front of the car is impacted, the front bumper beam assembly and the sub-bumper beam assembly can evenly distribute the impact force, and then the impact force is absorbed by the front bumper beam energy-absorbing box and the energy-absorbing box, thereby reducing the deformation of the passenger compartment and the longitudinal beam.

[0025] In a further embodiment of the present invention, the first connecting member includes a first connecting plate, the two ends of which are bent toward the front anti-collision beam and the sub-anti-collision beam respectively, and the first connecting plate is connected to the front anti-collision beam by bolts.

[0026] In this solution, by bending the two ends of the first connecting plate toward the front bumper beam and the sub-bumper beam respectively, the collision torque is facilitated to be transmitted between the front bumper beam assembly and the sub-bumper beam assembly. By connecting the first connecting plate to the front bumper beam with bolts, the installation of the sub-bumper beam is facilitated, thus improving installation efficiency.

[0027] In a further embodiment of the invention, the two energy-absorbing boxes are parallel to each other, the two front bumper beam energy-absorbing boxes are parallel to each other, and the two energy-absorbing boxes are parallel to the front bumper beam energy-absorbing boxes and located directly above the energy-absorbing boxes.

[0028] In this design, by setting two energy-absorbing boxes parallel to the two front bumper beam energy-absorbing boxes, the impact force received by the car in the Y direction can be absorbed evenly.

[0029] The second aspect of the present invention provides an automobile, including a front cabin module, a floor module and a rear cabin module. The front cabin module includes the anti-collision energy absorption structure of the front end of the automobile provided in the first aspect of the present invention, a longitudinal beam disposed on the floor module and a front bulkhead, and a front anti-collision beam assembly disposed on the longitudinal beam.

[0030] In a further embodiment of the present invention, the floor module and the rear cabin module, the front cabin module and the rear cabin module are respectively disposed at the front and rear ends of the floor module, and the floor module integrates a battery pack and high-voltage accessories.

[0031] In this solution, by integrating the battery pack and high-voltage accessories into the floor, the vehicle's Z-axis space can be effectively saved, facilitating overall maintenance; at the same time, since the vehicle door sill is installed on the floor module, the height of the vehicle door sill is reduced.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] This invention effectively reduces deformation of the upper part of the front compartment during a car collision by installing a secondary anti-collision beam assembly between the original front anti-collision beam assembly and the shotgun assembly. After the secondary anti-collision beam is impacted, the energy-absorbing box installed on the secondary anti-collision beam can absorb part of the impact force. Only then will the impact force be transmitted to the shotgun assembly through the second connector, thus protecting the occupant's thighs. The secondary anti-collision beam is connected to the front anti-collision beam assembly through the first connector, and at the same time, it distributes the impact force on the front of the car, which can increase the initial energy absorption and reduce the deformation of the passenger compartment. At the same time, since the secondary anti-collision beam assembly is located in the front compartment of the car, it increases the energy absorption of the front of the car, thereby reducing the energy absorption requirement of the rear of the engine compartment, and thus achieving the goal of overall vehicle weight reduction.

Therefore, they should not be construed as limitations on this invention.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0056] This invention addresses the problems existing in the prior art by proposing a general inventive concept to solve these problems. By adding a secondary anti-collision beam assembly to the anti-collision energy absorption structure 11 in the front passenger compartment, the invention connects the Shotgun assembly 300 and the front anti-collision beam assembly respectively, thereby achieving the effect of anti-collision energy absorption at the upper front of the vehicle 1 and effectively reducing the deformation of the passenger compartment during a collision.

[0057] Please see Figures 1-7 The first aspect of the present invention provides a collision-resistant energy-absorbing structure 11 for the front end of a vehicle, disposed in the front compartment of a vehicle 1, the collision-resistant energy-absorbing structure 11 comprising:

[0058] Front bumper beam assembly (not shown in the figure), used for front-end collision protection of vehicle 1;

[0059] Shotgun assembly 300, used to enhance the side strength of vehicle 1;

[0060] And the secondary anti-collision beam assembly (not shown in the figure), including the secondary anti-collision beam 210 and the energy-absorbing box 230;

[0061] The sub-collision beam 210 is provided with a first connector 220 that connects to the front collision beam 110, and the energy-absorbing box 230 is provided with a second connector 240 that connects to the shotgun assembly 300. The sub-collision beam 210 is located above the front collision beam 110 and is used to reduce the deformation of the passenger compartment when the car 1 collides.

[0062] This invention effectively reduces the deformation of the upper part of the front compartment of the vehicle 1 during a collision by setting a secondary anti-collision beam assembly between the original front anti-collision beam assembly and the shotgun assembly 300. After the secondary anti-collision beam 210 is impacted, the energy-absorbing box 230 set on the secondary anti-collision beam 210 can absorb part of the impact force. Then the impact force is transmitted to the shotgun assembly 300 through the second connector 240, thus protecting the occupant's thighs. The secondary anti-collision beam 210 is connected to the front anti-collision beam assembly through the first connector 220, and at the same time, it distributes the impact on the front of the vehicle 1, which can increase the initial energy absorption and reduce the deformation of the passenger compartment. At the same time, since the secondary anti-collision beam assembly is set in the front compartment of the vehicle 1, it increases the energy absorption of the front of the vehicle 1, thus reducing the energy absorption requirement of the rear of the engine compartment, thereby achieving the purpose of vehicle weight reduction.

[0063] Understandably, the Shotgun assembly 300 in this application refers to the longitudinal beam on which the front fender is mounted, located on the outermost side of the engine compartment; the anti-collision beam is a device used to reduce the impact energy absorbed when the vehicle is involved in a collision, consisting of a main beam, energy-absorbing elements, and a mounting plate connected to the vehicle 1. Both the main beam and the energy-absorbing elements can effectively absorb collision energy during low-speed collisions, minimizing the damage to the longitudinal beams of the vehicle body, thus playing its protective role for the vehicle; the front anti-collision beam assembly refers to the anti-collision mechanism installed in the front engine compartment of the vehicle 1 and connected to the longitudinal beam; the secondary anti-collision beam assembly refers to an additional energy-absorbing component installed in the front engine compartment of the vehicle 1; the energy-absorbing box 230 and the front anti-collision energy-absorbing box 230 refer to a component of the vehicle 1 that can collapse and absorb energy during a collision, improving the safety of the vehicle 1. In the X, Y, and Z directions mentioned in this document, the X direction refers to the longitudinal direction of the vehicle 1, the Y direction refers to the lateral direction of the vehicle 1, and the Z direction refers to the vertical direction; the A-pillar is the connecting pillar connecting the roof and the front compartment on the left and right front sides.

[0064] It should be noted that, Figure 2 This is a schematic diagram of torque transmission in a collision avoidance and energy absorption structure 11 for the front end of a car, provided in one embodiment of the present invention. Figure 2 The arrows in the diagram indicate the torque transmission path. ① refers to the torque transmission path at the lower front end of vehicle 1, i.e., from the front bumper beam 110 - front bumper beam energy-absorbing box 120 - longitudinal beam sequentially; ② refers to the torque transmission path at the upper front end of vehicle 1, i.e., from the secondary bumper beam 210 - energy-absorbing box 230 - shotgun assembly 300 - A-pillar sequentially. The torques on the upper and lower parts can also be transmitted through the first connecting member 220 to achieve energy absorption distribution. Meanwhile, this demonstrates the prior art. Figure 1 In the middle, there is also an arrow symbol indicating the path of torque transmission.

[0065] In a further embodiment of the present invention, the front bumper beam assembly includes:

[0066] Front bumper beam 110 and front bumper beam energy absorption box 120;

[0067] The front bumper beam energy-absorbing box 120 is used to connect with the longitudinal beam of the vehicle 1.

[0068] In this solution, by setting the front bumper beam assembly as a front bumper beam 110 and a front bumper beam energy absorption box 120, the energy absorption of the front of the vehicle 1 can be effectively improved. When the vehicle 1 is hit, the front bumper beam 110 will transfer the impact force to the front bumper beam energy absorption box 120. After the energy absorption box 230 absorbs part of the impact force, it will be transferred to the chassis through the longitudinal beam, thereby improving the energy absorption of the vehicle 1 when it is hit and preventing damage to the chassis of the vehicle 1.

[0069] In a further embodiment of the present invention, both the front bumper beam 110 and the secondary bumper beam 210 are arc-shaped, and the curvature of the front bumper beam 110 and the secondary bumper beam 210 is the same.

[0070] In this design, by setting both the front bumper beam 110 and the secondary bumper beam 210 to be arc-shaped, the impact force transmitted from all directions during a collision of the vehicle 1 can be absorbed. At the same time, by setting the curvature of the front bumper beam 110 and the secondary bumper beam 210 to be consistent, the front bumper beam 110 and the secondary bumper beam 210 can simultaneously transmit the impact force received by the vehicle 1. The energy is then absorbed by the energy-absorbing box 230 and the energy-absorbing box 120 of the front bumper beam, thereby effectively reducing the deformation of the passenger compartment and improving the protective effect of this structure.

[0071] Furthermore, since the front bumper beam 110 and the secondary bumper beam 210 are connected, the energy-absorbing box 230 and the secondary bumper beam 210, as well as the front bumper beam 110 and the front bumper beam energy-absorbing box 120, can be connected by a snap-fit ​​connection and a threaded connection. When it is necessary to extend the Y-direction of the vehicle 1, that is, to widen the design of the vehicle 1, it is only necessary to adjust the spacing between the energy-absorbing box 230 (including the mechanism connected to the energy-absorbing box 230) and the front bumper beam energy-absorbing box 120 (including the front bumper beam 110 and the secondary bumper beam 210, i.e. the longitudinal beam part) to widen the distance. In order to facilitate widening, the crossbeam connecting the longitudinal beam is also designed to facilitate lengthening.

[0072] Please refer to further information. Figure 7 , Figure 7 The diagram shows the connection structure of the second connector 240. In the diagram, 310 refers to the front connecting plate on the Shotgun assembly 300 that is connected to the second connector 240. In a further embodiment of the present invention, the second connector 240 includes a second connecting plate and a connecting bolt 500. The second connecting plate is provided with four connecting holes (not shown in the diagram). The Shotgun assembly 300 is provided with four mating threaded holes that mate with the connecting holes (not shown in the diagram). The connecting bolt 500 passes through the connecting holes and is threadedly connected to the mating threaded holes.

[0073] In this design, the second connector 240 is configured as a connecting plate, which is generally square. A connecting hole is provided at each of the four corners of the connecting plate. Threaded holes corresponding to the four connecting holes are provided on the Shotgun assembly 300. Connecting bolts 500 pass through the connecting holes and are threaded into the threaded holes, thus connecting the second connecting plate to the Shotgun assembly 300. Since the second connecting plate is mounted on the energy-absorbing box 230, the connection between the sub-collision beam assembly and the Shotgun assembly 300 is achieved. The threaded connection facilitates the assembly and connection of the sub-collision beam assembly and the Shotgun assembly 300, improving installation efficiency. The connecting plate can also adopt other shapes, with its connecting holes located along its edges and evenly distributed.

[0074] Regarding the connection between the second connecting plate and the Shotgun assembly 300, the present invention provides an optimized solution (not illustrated): structural adhesive is applied to the connection surface between the second connecting plate and the Shotgun assembly 300 to improve the strength of the connection between the two.

[0075] In a further embodiment of the present invention, two energy-absorbing boxes 230 and two front anti-collision beam energy-absorbing boxes 120 are provided. The two energy-absorbing boxes 230 are symmetrically arranged on the secondary anti-collision beam 210, and the two front anti-collision beam energy-absorbing boxes 120 are symmetrically arranged on the front anti-collision beam 110.

[0076] In this solution, by setting two energy-absorbing boxes 230, when the car 1 is hit, the impact force received by the secondary anti-collision beam 210 can be evenly absorbed by the energy-absorbing boxes 230 on both sides, which improves the energy absorption effect and protects the shotgun assemblies 300 on both sides of the car 1; similarly, the front anti-collision beam energy-absorbing box 120 can also effectively absorb the impact force on both sides, thereby effectively protecting the longitudinal beams in the car 1.

[0077] In a further embodiment of the present invention, two first connectors 220 are provided, and the two first connectors 220 are symmetrically arranged. One end of the two first connectors 220 is disposed between the two front anti-collision beam energy absorption boxes 120, and the other end is disposed between the two energy absorption boxes 230.

[0078] It should be noted that in some alternative solutions, the two first connectors 220 are the basic structure for realizing the torque transmission function of the first connectors 220. In order to better transmit torque, more first connectors 220 can be set and arranged symmetrically.

[0079] In this solution, by placing two first connectors 220 between two front bumper beam energy-absorbing boxes 120, when the front end of the vehicle 1 is impacted, the front bumper beam assembly and the sub-bumper beam assembly can evenly distribute the impact force, and then the front bumper beam energy-absorbing box 120 and energy-absorbing box 230 absorb the impact force, thereby reducing the deformation of the passenger compartment and the longitudinal beam.

[0080] Regarding the front bumper beam 110, the secondary bumper beam 210, and their connection method, the present invention provides an alternative solution (not illustrated in this solution). In this solution, the front bumper beam 110 and the secondary bumper beam 210 are made to have the same shape, and their two ends are connected by a first connector 220. To facilitate the Y-axis extension of the vehicle 1, the front bumper beam 110 and the secondary bumper beam 210 should also be made to be arc-shaped, and their curvatures should be consistent. The front bumper beam 110 and the secondary bumper beam 210 adopting the same shape facilitates production and assembly, and improves the versatility of parts. Similarly, the energy-absorbing box 230 and the front bumper beam energy-absorbing box 120 can also be made to have the same shape.

[0081] Please refer to the following: Figure 6 , Figure 6 A schematic diagram of the structure of the first connecting plate at both ends, the front anti-collision beam 110, and the secondary anti-collision beam 210; In a further embodiment of the present invention, the first connecting member 220 includes a first connecting plate, the two ends of which are bent toward the front anti-collision beam 110 and the secondary anti-collision beam 210 respectively, and the first connecting plate is connected to the front anti-collision beam 110 by bolts.

[0082] In this solution, by bending the two ends of the first connecting plate toward the front bumper beam 110 and the secondary bumper beam 210 respectively, the collision torque is facilitated to be transmitted between the front bumper beam assembly and the secondary bumper beam assembly. By connecting the first connecting plate to the front bumper beam 110 with bolts, the installation of the secondary bumper beam 210 is facilitated, and the installation efficiency is improved.

[0083] Regarding the connection method between the first connecting plate and the secondary anti-collision beam 210 and the front anti-collision beam 110, the present invention provides an alternative solution (not illustrated). In this solution, one end of the first connecting plate can be welded to one of the secondary anti-collision beam 210 or the front anti-collision beam 110, and the other end can be connected to the other of the secondary anti-collision beam 210 or the front anti-collision beam 110 by a snap-fit ​​connection.

[0084] In a further embodiment of the present invention, the two energy-absorbing boxes 230 are parallel to each other, the two front bumper beam energy-absorbing boxes 120 are parallel to each other, and the two energy-absorbing boxes 230 are parallel to the front bumper beam energy-absorbing boxes 120 and located directly above the energy-absorbing boxes 230. In this embodiment, by setting the two energy-absorbing boxes 230 and the two front bumper beam energy-absorbing boxes 120 to be parallel to each other, the impact force received by the vehicle 1 in the Y direction can be absorbed evenly, so that the front bumper beam assembly and the sub-bumper beam assembly can evenly distribute the impact force received by the vehicle 1 during a collision, thereby effectively reducing the deformation of the passenger compartment and improving safety performance.

[0085] Furthermore, regarding the Shotgun assembly 300, which is connected to the A-pillar of the vehicle 1, the impact on the front top of the vehicle 1 is transmitted through the sub-anti-collision beam 210 to the energy-absorbing box 230. The energy-absorbing box 230 absorbs the torque and causes it to dissipate before being transmitted to the Shotgun assembly 300, thereby effectively protecting the A-pillar and the Shotgun assembly 300 and preventing the passenger compartment from being squeezed and deformed.

[0086] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of a car 1 provided in one embodiment of the present invention. The second aspect of the present invention provides a car 1, including a front cabin module 10, a floor module 20 and a rear cabin module 30. The front cabin module 10 includes a collision-resistant energy-absorbing structure 11 for the front end of a car provided in the first aspect of the present invention, a longitudinal beam disposed on the floor module 20 and a front bulkhead (not shown in the figure), and a front anti-collision beam assembly disposed on the longitudinal beam.

[0087] In a further embodiment of the present invention, the floor module 20 and the rear cabin module 30, the front cabin module 10 and the rear cabin module 30 are respectively disposed at the front and rear ends of the floor module 20, and the floor module 20 integrates a battery pack (not shown in the figure) and high voltage accessories (not shown in the figure).
