DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work are within the scope of protection of the present application. In order to make the technical solutions and advantages of the present application more clear, the front compartment assembly structure and vehicle will be described in detail below in combination with the drawings.

[0056] Electric vehicles are popular due to their environmental protection, high energy utilization rate and low vehicle cost. Compared with traditional fuel vehicles, electric vehicles lack longitudinal beam structure in the lower part of the vehicle body due to the arrangement of the battery. The connection point between the front apron and the front door hinge column in the vehicle is usually designed as a welded or bolted connection, which may cause stress concentration at the connection point. In the event of a collision, the front apron is prone to compression deformation under the action of the collision force and intrudes into the interior of the passenger compartment, which may cause injury to the passengers and even damage to the battery pack, thereby threatening the safety of the driver and passengers.

[0057] To this end, the application provides a front compartment assembly structure of a vehicle, as shown in the drawings, the front compartment assembly structure can include a front door hinge column 1, a front apron 2 and a support 3; the front door hinge column 1 is located on one side of the front apron 2 along the width direction of the vehicle and is connected with the front apron 2 to form an included angle space 21; the support 3 is located in the included angle space 21 and is connected with the front door hinge column 1 and the front apron 2 respectively. Figure 1

[0058] Figure 1 In the drawings, the X direction indicates the width direction of the vehicle, the Y direction indicates the length direction of the vehicle, and the Z direction indicates the height direction of the vehicle.

[0059] In the front compartment assembly structure of the vehicle provided in the embodiments of the application, the support 3 is arranged in the included angle space 21 formed by the front apron 2 and the front door hinge column 1, and the support 3 is connected with the front door hinge column 1 and the front apron 2 respectively, so as to form a collision force conduction channel between the front door hinge column 1, the support 3 and the front apron 2. When the vehicle is subjected to a front collision force, the collision force can be transmitted to the front door hinge column 1 through the front apron 2 and the support 3, thereby dispersing the collision force and avoiding stress concentration at the connection point of the front apron 2 and the front door hinge column 1, thereby avoiding excessive deformation of the front apron 2 in the event of a collision. In addition, the support 3 can provide a support force to the front apron 2 in the opposite direction of the collision force, further avoiding excessive deformation of the front apron 2, preventing the front apron from intruding into the interior of the vehicle, and improving the safety factor of the vehicle.

[0060] In some embodiments, the number of supports 3 can be multiple, and the supports 3 are arranged in the included angle space 21 in the height direction Z of the vehicle at intervals. Each support 3 is connected with the front door hinge column 1 and the front apron 2 respectively to support multiple positions of the connection between the front door hinge column 1 and the front apron 2 in the height direction of the vehicle, further avoiding the excessive deformation of the front apron 2 in the event of a collision, and having a higher safety factor. Those skilled in the art can select and adjust the number of supports 3 according to actual needs.

[0061] ​Optionally, the support 3 is a reinforcing rib, two ends of the reinforcing rib are connected with the front wall 2 and the front door hinge pillar 1 respectively to form a rigid support between the two.

[0062] However, the reinforcing rib can achieve a certain supporting effect, but due to its own shape and size limitations, it is easy to bend or even break when subjected to shear force. Therefore, in an implementation manner of the embodiment of the present application, the support 3 can be a convex structure with one side open, and the edge of the open side of the convex structure is connected with the side surface of the front wall 2 along the length direction of the vehicle and the side surface of the front door hinge pillar 1 along the width direction respectively. In this way, as shown in Figure 1 , the support 3 can be connected with the front wall 2 and the front door hinge pillar 1 along the two side edges of the included angle space 21 respectively to fill the included angle part of the included angle space 21, avoiding the deformation of the included angle space 21 due to the collision.

[0063] It should be noted that the "convex structure" refers to a part of the plate used to make the support 3 protruding in a certain direction to form a convex. Compared with the plate-shaped structure such as the reinforcing rib, the support 3 formed as a "convex structure" can withstand greater shear force through the convex part.

[0064] In the front compartment assembly structure provided by the embodiment of the present application, by setting the support 3 as a convex structure, compared with the reinforcing rib in the above embodiment, the support 3 is not easy to bend and deform when subjected to collision force, so that the intrusion of the front wall 2 into the interior of the front compartment can be avoided, and the safety of passengers can be ensured.

[0065] In some embodiments, the support 3 includes a plate body and two connecting plates, the plate body includes a first part and a second part connected by bending, the first part is close to the front wall 2, the second part is close to the front door hinge pillar 1, and the two connecting plates are connected to the opposite two side edges of the plate body along the height direction Z of the vehicle in an inclined manner to form the above-mentioned convex structure, and the edges of the connecting plates away from the plate body are connected with the front wall 2 and the front door hinge pillar 1 respectively. In an implementation manner of the embodiment of the present application, as shown in Figure 1 and Figure 2As shown, the support 3 can be a triangular convex structure, wherein: two sides of the triangle corresponding to the support 3 are connected with the front wall 2 and the front door hinge column 1 respectively, and the plane where the triangle is located intersects with the plane where the front wall 2 is located. That is, the above-mentioned connecting plate can be roughly triangular, and the connecting plate is connected with the front wall 2 intersectingly, so that one vertex angle (for example, the vertex angle corresponding to the side of the connecting plate away from the plate body) of the triangular convex structure is inserted into the included angle space 21, and two sides forming the vertex angle are connected with the front wall 2 and the front door hinge column 1 respectively. The front compartment assembly structure provided by the embodiment of the present application fills the included angle space 21 with a triangular convex structure, and the triangular structure is relatively stable and can bear greater load. In some embodiments, the vertex angle of the connecting plate away from the plate body can be substantially the same as the angle of the included angle space 21.

[0066] Further, in an implementation manner of the embodiment of the present application, as shown in Figure 2 The support 3 can include a main body part 31 and a first flange 32, the first flange 32 surrounds the circumferential edge of the main body part 31, and the first flange 32 is connected with the front wall 2 and the front door hinge column 1 in a closed manner. In some embodiments, the main body part 31 can include the above-mentioned plate body and two connecting plates, and the first flange 32 can be connected to the side edge away from the plate body of the connecting plate and bent relative to the plate body.

[0067] In some embodiments, the first flange 32 surrounds the circumferential edge of the main body part 31 without interruption in the middle and is connected end to end. By connecting the first flange 32 with the front wall 2 and the front door hinge column 1 in a closed manner, a closed space is formed between the front wall 2 and the front door hinge column 1. The boundary of the closed space is generally fixed, which can provide additional constraints and support, thereby helping to enhance the bending resistance of the structure, so that the structure inside the closed space is relatively stable and can effectively bear the external collision force. That is, the arrangement of the first flange 32 not only increases the connection area of the support 3 with the front wall 2 and the front door hinge column 1, increases the connection strength of the support 3 with the two, and forms a closed space between the front wall 2 and the front door hinge column 1, thereby greatly reducing the possibility of excessive deformation of the front wall 2.

[0068] In an implementation manner of the embodiment of the present application, as shown in Figure 3 The front compartment assembly structure can include a front wall upper cross beam 4, the front wall upper cross beam 4 and the support 3 are located on opposite sides of the front wall 2 along the length direction Y of the vehicle respectively, and the front wall upper cross beam 4 is connected with the front wall 2 and the front door hinge column 1 respectively; the orthographic projection of the front wall upper cross beam 4 on the projection plane at least partially overlaps the orthographic projection of the support 3 on the projection plane, and the projection plane is perpendicular to the length direction Y.

[0069] When the vehicle is subjected to a front collision, the collision force is generally transmitted to the front apron upper beam 4 through the front longitudinal beam, and then transmitted to the front apron 2 through the front apron upper beam 4. In order to avoid excessive deformation of the front apron 2 when subjected to the collision force, in the front compartment assembly structure provided in the embodiments of the present application, the support member 3 described above is arranged on the side of the front apron 2 away from the front apron upper beam 4, and the position of the support member 3 in the height direction Z of the vehicle is substantially the same as that of the front apron upper beam 4, so that the collision force transmitted to the front apron 2 through the front apron upper beam 4 can be directly transmitted to the support member 3, and the support member 3 provides a support force for the front apron 2 and the corresponding front apron upper beam 4 to offset at least part of the collision force, thereby avoiding the excessive deformation of the front apron 2.

[0070] In some embodiments, the extension length of the orthographic projection of the support member 3 on the projection plane in the height direction Z of the vehicle can be greater than or equal to the extension length of the orthographic projection of the front apron upper beam 4 on the projection plane in the height direction Z of the vehicle, so that in the portion provided with the support member 3, the orthographic projection of the front apron upper beam 4 is located inside the orthographic projection of the support member 3, and the collision force transmitted to the front apron upper beam 4 can be directly transmitted to the support member 3.

[0071] It should be noted that the interval distance between the edges on the opposite sides of the support member 3 in the height direction of the vehicle can be determined as the "extension length of the orthographic projection of the support member 3 on the projection plane in the height direction of the vehicle", and the interval distance between the edges on the opposite sides of the front apron upper beam 4 in the height direction of the vehicle can be determined as the "extension length of the orthographic projection of the front apron upper beam 4 on the projection plane in the height direction of the vehicle". Moreover, considering that the support member 3 and the front apron upper beam 4 can be arranged in irregular shapes with uneven heights, the above-mentioned extension length can be understood as the maximum interval distance between the edges on the opposite sides in the height direction of the vehicle.

[0072] In one implementation manner of the embodiments of the present application, as shown in Figure 1 and Figure 3 , the front compartment assembly structure can further include a floor panel 5, a front floor longitudinal beam 6, and a first transmission member 7; the floor panel 5 is located on one side of the front apron 2 in the height direction of the vehicle and connected with the front apron 2; the front floor longitudinal beam 6 is fixed to the floor panel 5 and located on the same side of the support member 3 as the front apron 2; and the first transmission member 7 is located on the side of the support member 3 close to the front floor longitudinal beam 6, and the first transmission member 7 is connected with the front apron 2, the front door hinge pillar 1, and the front floor longitudinal beam 6, respectively.

[0073] In the front compartment assembly structure provided in the embodiments of the present application, the bottom plate 5 can be arranged below the front wall 2, and the upper surface of the bottom plate 5 is provided with a front floor longitudinal beam 6. By arranging the first conducting member 7 between the front wall 2 and the front floor longitudinal beam 6, the collision force conducted to the front wall 2 can be conducted to the front floor longitudinal beam 6 through the first conducting member 7 to disperse a part of the collision force, and the front floor longitudinal beam 6 can also support the front wall 2 through the first conducting member 7. The collision force conducting channel between the front wall 2, the support member 3 and the front door hinge column 1 can be referred to as a first collision force conducting channel; the collision force conducting channel formed between the front wall 2, the first conducting member 7 and the front floor longitudinal beam 6 can be referred to as a second collision force conducting channel; and the first conducting member 7 is also connected with the front door hinge column 1, so that a part of the collision force conducted to the front wall 2 can be conducted to the front door hinge column 1 to disperse a part of the collision force. The collision force conducting channel formed between the front wall 2, the first conducting member 7 and the front door hinge column 1 can be referred to as a third collision force conducting channel.

[0074] In one implementation manner of the embodiments of the present application, as shown in Figure 3 and Figure 5 The front compartment assembly structure can further include a front wall lower cross beam 8, which can be arranged on the same side of the front wall 2 as the front wall upper cross beam 4 and below the front wall upper cross beam 4. Since the front wall upper cross beam 4 is correspondingly arranged on the opposite sides of the front wall 2 as the support member 3, the front wall lower cross beam 8 and the support member 3 can be respectively arranged on the opposite sides of the front wall 2 along the length direction of the vehicle, and in the height direction of the vehicle, the front wall lower cross beam 8 is below the support member 3. The front wall lower cross beam 8 is connected with the front door hinge column 1, and the orthographic projection of the front wall lower cross beam 8 on a projection plane at least partially overlaps the orthographic projection of the first conducting member 7 on the projection plane, and the projection plane is perpendicular to the length direction.

[0075] When the vehicle is subjected to a front collision, the collision force is generally transmitted to the front wall lower cross beam 8, and the collision force is transmitted to the front wall 2 through the front wall lower cross beam 8. In order to avoid that the front wall 2 is excessively extruded by the front wall lower cross beam 8 and excessively deformed when subjected to the collision force, in the front compartment assembly structure provided in the embodiments of the present application, the first conducting member 7 is arranged on the side of the front wall 2 away from the front wall lower cross beam 8, and the position of the first conducting member 7 in the height direction of the vehicle is substantially the same as that of the front wall lower cross beam 8, so that the collision force conducted to the front wall 2 through the front wall lower cross beam 8 can be directly conducted to the first conducting member 7, and the first conducting member 7 gives the front wall 2 a supporting force to offset at least a part of the collision force, thereby avoiding the excessive deformation of the front wall 2.

[0076] In some embodiments, the extension length of the front projection of the first conducting member 7 on the projection plane in the height direction of the vehicle can be greater than or equal to the extension length of the front projection of the under dash cross beam 8 on the projection plane in the height direction of the vehicle, so that in the portion provided with the first conducting member 7, the front projection of the under dash cross beam 8 can be located inside the front projection of the first conducting member 7, so that the collision force conducted to the under dash cross beam 8 can be directly conducted to the first conducting member 7.

[0077] It should be noted that the interval distance between the edges on opposite sides of the first conducting member 7 in the height direction of the vehicle can be determined as the "extension length of the front projection of the first conducting member 7 on the projection plane in the height direction of the vehicle", and the interval distance between the edges on opposite sides of the under dash cross beam 8 in the height direction of the vehicle can be determined as the "extension length of the front projection of the under dash cross beam 8 on the projection plane in the height direction of the vehicle". Moreover, considering that the first conducting member 7 and the under dash cross beam 8 can be arranged in irregular shapes with uneven heights, the above-mentioned extension length can be understood as the maximum interval distance between the edges on opposite sides in the height direction of the vehicle.

[0078] In some embodiments of the present application, the first conducting member 7 can be a convex structure.

[0079] It should be noted that the "convex structure" refers to a part of the plate material used to manufacture the first conducting member 7 being convex in a certain direction to form a convex, and the "convex structure" can withstand greater shear force compared to plate-shaped structures such as reinforcing ribs.

[0080] In the front compartment assembly structure provided in the embodiments of the present application, the first conducting member 7 is a convex structure, which is not easy to bend and deform when subjected to collision force, so as to avoid the intrusion of the front panel 2 into the interior of the front compartment and ensure the safety of passengers.

[0081] Exemplarily, as shown in FIG. 1, the first conducting member 7 can be arranged on the front panel 2, and the under dash cross beam 8 can be arranged on the front compartment 3. Figure 1As shown, the first conducting member 7 can be a triangular convex structure, and the base of the triangle corresponding to the first conducting member 7 is attached to the front wall 2. In other words, the orthographic projection of the first conducting member 7 on the plane where the front wall 2 is located can be substantially triangular. The first conducting member 7 can include intersecting first and second connecting portions, wherein the top corner of the first and second connecting portions is fixed to the front wall 2, the side of the first connecting portion away from the top corner is connected to the front door hinge column 1, and the side of the second connecting portion away from the top corner is connected to the front floor longitudinal beam 6. The first and second connecting portions correspond to one side of the triangle, respectively, and the side of the first connecting portion away from the top corner and the side of the second connecting portion away from the top corner are connected to each other to correspond to the third side of the triangle, thereby forming a triangular convex structure. The triangular structure is relatively stable, so that the first conducting member 7 can bear greater load.

[0082] In an implementation form of the embodiment of the present application, as shown in Figure 4 and Figure 5 The front compartment assembly structure can further include a rocker longitudinal beam 9 and a second conducting member 10. The rocker longitudinal beam 9 is connected to the lower end of the front door hinge column 1 in the height direction. The second conducting member 10 is at least partially located between the front wall lower cross beam 8 and the rocker longitudinal beam 9, and one side of the second conducting portion 102 is connected to the front wall lower cross beam 8, and the other side is connected to at least one of the front door hinge column 1 and the rocker longitudinal beam 9.

[0083] The second conducting member 10 is arranged between the front wall lower cross beam 8 and the front door hinge column 1. After the collision force is transmitted to the front wall lower cross beam, at least part of the collision force can be dispersed to the front door hinge column 1 and / or the rocker longitudinal beam 9 through the second conducting member 10, so as to form a fourth collision force conducting channel between the front wall lower cross beam 8, the second conducting member 10 and the front door hinge column 1, and a fifth collision force conducting channel between the front wall lower cross beam 8, the second conducting member 10 and the rocker longitudinal beam 9. The collision force applied by the front wall lower cross beam 8 to the front wall 2 is reduced, thereby avoiding the excessive deformation of the front wall 2 when subjected to the collision force, preventing the front wall 2 from intruding into the front compartment, and improving the safety factor of the whole vehicle.

[0084] In an implementation form of the embodiment of the present application, as shown in Figure 6 and Figure 7 The second conducting member 10 can include a first conducting portion 101 and a second conducting portion 102. The first conducting portion 101 is connected to the side of the front wall lower cross beam 8 close to the rocker longitudinal beam 9. In the height direction, the second conducting portion 102 is located above the first conducting portion 101, the second conducting portion 102 is connected to the side of the first conducting portion 101 away from the front wall lower cross beam 8, and is bent upward relative to the first conducting portion 101, and the second conducting portion 102 is connected to the front door hinge column 1.

[0085] In the front compartment assembly structure provided in the embodiments of the present application, the first conducting part 101 is arranged between the front wall lower cross beam 8 and the rocker longitudinal beam 9, and can disperse the collision force conducted to the front wall lower cross beam 8 to the rocker longitudinal beam 9. The second conducting part 102 is located above the first conducting part 101 and is connected to the edges of the first conducting part 101 by bending. The second conducting part 102 is also connected to the front door hinge column 1. Part of the collision force conducted to the first conducting part 101 can also be dispersed to the front door hinge column 1 through the second conducting part 102, thereby avoiding excessive extrusion of the front wall lower cross beam 8 to the front wall 2.

[0086] In some embodiments, as shown in Figure 5 The front compartment assembly structure can further include a front longitudinal beam 104 connected to the front wall upper cross beam 4 and the second conducting part 102, respectively. When subjected to a front collision force, the front longitudinal beam 104 can directly conduct the collision force to the front wall upper cross beam 4 and the second conducting part 102. That is, the second conducting part 102 can simultaneously disperse the collision force conducted to the first conducting part 101 and the collision force on the front longitudinal beam 104 to the front door hinge column 1. The collision force conducted to the front longitudinal beam 104 and the front wall upper cross beam 4 is reduced, thereby avoiding excessive extrusion of the front wall upper cross beam 4 to the front wall 2 and preventing the front wall 2 from intruding into the front compartment.

[0087] In one implementation manner of the embodiments of the present application, as shown in Figure 9 The first conducting part 101 can include a second flange 1011 and a third flange 1012 connected by bending. The second flange 1011 is connected to the first side surface 91 of the rocker longitudinal beam 9, and the third flange 1012 is connected to the second side surface 92 of the rocker longitudinal beam 9. The first side surface 91 and the second side surface 92 are adjacent to each other. The first side surface 91 is a side surface of the rocker longitudinal beam 9 along the width direction, and the second side surface 92 is a side surface of the rocker longitudinal beam 9 along the height direction.

[0088] The second flange 1011 and the third flange 1012 are connected by bending to form a connecting space between the second flange 1011 and the third flange 1012. The second flange 1011 is connected to the first side surface 91 of the rocker longitudinal beam 9, and the third flange 1012 is connected to the second side surface 92 of the rocker longitudinal beam 9. The connecting area of the first conducting part 101 and the rocker longitudinal beam 9 is increased, and the connecting strength of the first conducting part 101 and the rocker longitudinal beam 9 is enhanced. At the same time, the third flange 1012 of the first conducting part 101 is overlapped to the bottom of the rocker longitudinal beam 9, so that the collision force conducted to the first conducting part 101 can be dispersed to the rocker longitudinal beam 9, thereby avoiding excessive extrusion of the front wall lower cross beam 8 to the front wall 2.

[0089] In one implementation manner of the embodiments of the present application, as shown in Figure 8 and Figure 9As shown, the second conducting member 10 further comprises a reinforcing portion 103, which is located in a space surrounded by the first conducting portion 101 and the second conducting portion 102, and is connected with the first conducting portion 101 and the second conducting portion 102 respectively. The reinforcing portion 103, the first conducting portion 101 and the second conducting portion 102 form a reinforcing space therebetween.

[0090] Since the first conducting portion 101 and the second conducting portion 102 are connected by edge bending, the structural strength of the connection is low, and stress concentration phenomenon is easy to occur. When subjected to impact force, deformation may occur. Therefore, in the front compartment assembly structure provided in the embodiment of the present application, the reinforcing portion 103 is additionally arranged between the first conducting portion 101 and the second conducting portion 102, and a reinforcing space is formed among the three. The reinforcing space is approximately triangular, and the internal structure of the triangular reinforcing space is relatively stable, which can effectively withstand external impact force, thereby forming support for the first conducting portion 101 and the second conducting portion 102, avoiding stress concentration phenomenon at the connection of the first conducting portion 101 and the second conducting portion 102, and being able to withstand more load when colliding.

[0091] Optionally, the reinforcing portion 103 is welded to the first conducting portion 101 and the second conducting portion 102.

[0092] The present application further provides a vehicle comprising the front compartment assembly structure of the vehicle as described above.

[0093] In the vehicle provided in the embodiment of the present application, the support member 3 is arranged in the included angle space 21 surrounded by the front wall 2 and the front door hinge column 1, and is connected with the front door hinge column 1 and the front wall 2 respectively. A collision force conducting channel is formed among the front door hinge column 1, the support member 3 and the front wall 2. When the vehicle is subjected to front collision force, the collision force can be transmitted to the front door hinge column 1 through the front wall 2 and the support member 3, thereby playing a role of dispersing the collision force, avoiding stress concentration at the connection point of the front wall 2 and the front door hinge column 1, and the support member 3 can give the front wall 2 a support force in the opposite direction of the collision force, thereby avoiding excessive deformation of the front wall 2 and improving the safety factor of the vehicle.
