Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a front body structure and vehicle. Background Technology

[0002] In vehicle body structures, a lower front bulkhead reinforcement beam is typically installed at the bottom of the front bulkhead. This beam increases the structural strength of the front of the vehicle and absorbs and disperses impact forces during a collision, reducing damage. However, current lower front bulkhead reinforcement beams in vehicle bodies still suffer from relatively weak structural strength, limiting the improvement of structural strength in the front of the vehicle and hindering further improvements in collision safety performance. Utility Model Content

[0003] In view of this, this application aims to propose a front structure for the vehicle body to further improve the collision safety of the vehicle.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0005] A front body structure, including a lower front bulkhead reinforcing beam located at the bottom of the front bulkhead;

[0006] The lower front bulkhead reinforcing beam is connected between the longitudinal beams of the front nacelle on the left and right sides, and there is space for arrangement at the lower front bulkhead reinforcing beam.

[0007] The space is equipped with a reinforcing member that extends along the left-right direction of the vehicle and is connected to the longitudinal beams of the front engine compartment on both sides.

[0008] Furthermore, a cavity is formed within the lower front bulkhead reinforcing beam, the cavity constituting the arrangement space, and the reinforcing member is located inside the lower front bulkhead reinforcing beam.

[0009] Furthermore, the reinforcing member is a tubular beam.

[0010] Furthermore, the reinforcing member is fixed inside the lower reinforcing beam of the front bulkhead by a first connecting bracket.

[0011] Furthermore, the first connecting brackets are a plurality of those arranged at intervals along the extending direction of the reinforcing member; and / or,

[0012] An installation space is formed between the first connecting bracket and the lower front reinforcement beam, and the reinforcement is fixed within the installation space.

[0013] Furthermore, the front lower reinforcing beam includes an upper reinforcing beam plate and a lower reinforcing beam plate connected below the upper reinforcing beam plate;

[0014] The upper plate of the reinforcing beam, the lower plate of the reinforcing beam, and the front panel together form the cavity, and the first connecting bracket is connected between the upper plate of the reinforcing beam and the lower plate of the reinforcing beam.

[0015] Furthermore, the reinforcing member is connected to the longitudinal beams of the front engine compartment on both sides via a second connecting bracket.

[0016] Furthermore, the second connecting bracket is connected to the lower front reinforcement beam.

[0017] Furthermore, a front bulkhead heat insulation plate mounting bracket is provided at the top of the lower front bulkhead reinforcing beam;

[0018] The front bulkhead heat insulation plate mounting bracket is connected to the longitudinal beams of the front engine compartment on both sides, and the front side of the front bulkhead heat insulation plate mounting bracket protrudes into the front engine compartment.

[0019] Compared with related technologies, this application has the following advantages:

[0020] (1) The front structure of the vehicle body described in this application, by setting up a space at the lower reinforcement beam of the front bulkhead and setting up a reinforcement member connected to the longitudinal beams of the front engine compartment on both sides in the space, can increase the structural strength and rigidity of the front bulkhead by utilizing the synergistic effect of the reinforcement member and the lower reinforcement beam of the front bulkhead. In the event of a frontal collision, the reinforcement member can also work with the lower reinforcement beam of the front bulkhead to prevent the components inside the front engine compartment from moving backward, reducing the compression of the passenger compartment and better protecting the occupants, thereby further improving the collision safety of the vehicle.

[0021] (2) This creates a cavity in the lower front bulkhead reinforcing beam, and the cavity in the lower front bulkhead reinforcing beam forms an arrangement space, so that the reinforcing member is located inside the lower front bulkhead reinforcing beam. On the one hand, the high strength of the cavity structure can be utilized to better increase the structural strength of the lower front bulkhead reinforcing beam itself. On the other hand, by placing the reinforcing member inside the lower front bulkhead reinforcing beam, it is convenient to arrange the reinforcing member at the front of the vehicle body, increasing the integration of the front structure of the vehicle body. At the same time, it can also avoid interference with surrounding parts, which would affect the arrangement of body parts in the front engine compartment.

[0022] (3) The reinforcement is made of tubular beams, which not only makes it easy to prepare the reinforcement and reduce the preparation cost of the reinforcement, but also makes it possible to increase the structural strength of the reinforcement by taking advantage of the high structural strength of the tubular beams, so that the reinforcement can have a better strengthening effect.

[0023] (4) The reinforcing member is fixed inside the lower reinforcing beam of the front enclosure through the first connecting bracket, which facilitates the fixed arrangement of the reinforcing member inside the lower reinforcing beam of the front enclosure. It also has the advantages of simple structure, easy design and implementation and low cost.

[0024] (5) The first connecting bracket is arranged in multiple intervals along the extension direction of the reinforcement, which can ensure the stability of the reinforcement in the front lower reinforcement beam, so that the reinforcement and the front lower reinforcement beam can give full play to the synergistic effect between them, so as to better increase the structural strength of the front of the vehicle body and improve the collision response capability during vehicle collision.

[0025] This arrangement creates an installation space between the first connecting bracket and the lower front reinforcement beam, and the reinforcement is fixed within this space. This not only ensures the stability of the reinforcement's position within the lower front reinforcement beam but also creates a ring structure between the first connecting bracket and the lower front reinforcement beam. The high strength of the ring structure further enhances the reliability of the connection between the reinforcement and the lower front reinforcement beam, thus improving the stability of the reinforcement within the lower front reinforcement beam and enhancing the synergistic effect between the reinforcement and the lower front reinforcement beam.

[0026] (6) The front lower reinforcement beam is mainly composed of the upper reinforcement beam plate and the lower reinforcement beam plate, so that the upper reinforcement beam plate, the lower reinforcement beam plate and the front panel together form the cavity inside the front lower reinforcement beam, and the first connecting bracket is connected between the upper reinforcement beam plate and the lower reinforcement beam plate. This makes the structure of the front lower reinforcement beam relatively simple and facilitates the formation of the cavity inside the front lower reinforcement beam, and also facilitates the connection between the first connecting bracket and the front lower reinforcement beam.

[0027] (7) This allows the reinforcing member to be connected to the longitudinal beams of the front engine compartment on both sides via the second connecting bracket, which facilitates the connection between the reinforcing member and the longitudinal beams of the front engine compartment on both sides. It also has the advantages of simple structure and easy implementation, and at the same time, it helps to ensure the stability of the connection between the reinforcing member and the longitudinal beams of the front engine compartment.

[0028] (8) The second connecting bracket is connected to the front bulkhead lower reinforcing beam. This allows the second connecting bracket to connect the reinforcing member to the front engine compartment longitudinal beam, and also allows the second connecting bracket to connect the reinforcing member to the front bulkhead lower reinforcing beam. This not only saves some of the first connecting bracket, which helps to reduce the vehicle weight and material cost, but also allows the second connecting bracket to connect the front bulkhead lower reinforcing beam, the reinforcing member and the front engine compartment longitudinal beam, increasing the connection strength between them, which is beneficial to improving the rigidity of the front of the vehicle.

[0029] (9) A front bulkhead heat shield mounting bracket is installed on the top of the front bulkhead lower reinforcing beam, and the front bulkhead heat shield mounting bracket is connected to the longitudinal beams of the front engine compartment on both sides. The front bulkhead heat shield mounting bracket also protrudes into the front engine compartment, which facilitates the installation and arrangement of the front bulkhead heat shield. At the same time, the connection between the front bulkhead heat shield mounting bracket and the longitudinal beams of the front engine compartment on both sides can be used to further increase the lateral connection and support structure at the front bulkhead position, which can better increase the structural strength of the front of the vehicle body and improve the response to vehicle collisions. By making the front bulkhead heat shield mounting bracket protrude into the front engine compartment, on the one hand, it can provide ample space for the front bulkhead heat shield. On the other hand, when the vehicle collides and the components inside the front engine compartment move backward, the front bulkhead heat shield mounting bracket has a certain collapse energy absorption capacity, which is beneficial to reduce the collision impact caused by the backward movement of the components inside the front engine compartment.

[0030] This application also proposes a vehicle that includes the front body structure described above.

[0031] The vehicle described in this application, by setting the aforementioned front body structure, can increase the structural strength and rigidity of the front body section. In the event of a frontal collision, it can also prevent the components inside the front engine compartment from shifting backward, reduce the compression of the passenger compartment, and better protect the occupants, thereby improving the vehicle's collision safety.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0054] An embodiment of the first aspect of this application provides a front body structure, which mainly relates to the improvement of the front bulkhead position of the vehicle body. Through its innovative structural design, the front body structure of this embodiment can increase the structural strength of the front bulkhead position, thereby improving the collision response capability of the front bulkhead position in vehicle collisions, especially frontal collisions, and thus improving the collision safety of the vehicle.

[0055] In related technologies, the front bulkhead lower reinforcement beam is one of the important structures of the front of the vehicle body. The front bulkhead lower reinforcement beam is generally set at the bottom of the front bulkhead, and it can increase the strength of the front body structure of the vehicle, and play a role in absorbing and dispersing the collision force and reducing collision damage when the vehicle is involved in a collision.

[0056] Currently, traditional lower front bulkhead reinforcement beams in vehicle bodies are typically made of stamped sheet metal and welded to one side of the front bulkhead panel 1. While this structure can increase the structural strength of the front bulkhead to some extent and absorb and transfer collision forces during a vehicle collision, its structural limitations still result in relatively weak structural strength at the front bulkhead and limited ability to absorb and transfer collision forces, thus hindering improvements in vehicle collision safety.

[0057] In view of this, in order to overcome the shortcomings of related technologies, the front structure of the vehicle body in this embodiment combines... Figures 1 to 5 As shown, the overall design includes a front lower reinforcing beam 3 located at the bottom of the front bulkhead 1.

[0058] The lower front bulkhead reinforcing beam 3 connects the left and right front engine compartment longitudinal beams 2, and a space Q is also provided at the lower front bulkhead reinforcing beam 3. A reinforcing member 4 is installed in this space Q, extending along the left and right direction of the vehicle, and the reinforcing member 4 is also connected to the front engine compartment longitudinal beams 2 on both sides.

[0059] Therefore, by setting up a space Q at the lower front bulkhead reinforcing beam 3 and setting up a reinforcing member 4 connected to the longitudinal beams 2 of the front engine compartment on both sides within the space Q, this embodiment can utilize the synergistic effect of the reinforcing member 4 and the lower front bulkhead reinforcing beam 3 to jointly increase the structural strength and rigidity of the front bulkhead of the vehicle. Furthermore, in the event of a frontal collision, the reinforcing member 4 can also work together with the lower front bulkhead reinforcing beam 3 to prevent the components inside the front engine compartment from moving backward, reducing the compression of the passenger compartment and better protecting the occupants, thereby further improving the vehicle's collision safety performance.

[0060] Based on the above overview, specifically, it remains as follows: Figures 1 to 3 As shown, the aforementioned lower front bulkhead reinforcing beam 3 is generally located on the front side of the front bulkhead 1, that is, on the side of the front bulkhead 1 facing the forward engine compartment. Furthermore, the lower front bulkhead reinforcing beam 3 can generally be made of sheet metal, and the lower front bulkhead reinforcing beam 3 is usually connected to the longitudinal beams 2 of the forward engine compartment on both sides by welding.

[0061] In this embodiment, we continue to combine Figures 1 to 5 As shown, in some exemplary embodiments, a cavity is also formed within the lower front bulkhead reinforcing beam 3, which constitutes the aforementioned arrangement space Q, and based on this, the reinforcing member 4 is specifically located inside the lower front bulkhead reinforcing beam 3.

[0062] In this way, by creating a cavity within the lower front bulkhead reinforcing beam 3, and this cavity constituting the aforementioned arrangement space Q, the reinforcing member 4 is located inside the lower front bulkhead reinforcing beam 3. On the one hand, this allows the high structural strength of the cavity to be utilized, thus better increasing the structural strength of the lower front bulkhead reinforcing beam 3 itself, and helping to enhance the overall rigidity of the front of the vehicle body. On the other hand, by placing the reinforcing member 4 inside the lower front bulkhead reinforcing beam 3, it is obviously easier to arrange the reinforcing member 4 at the front of the vehicle body, which helps to increase the integration of the front structure of the vehicle body, and at the same time, it can also avoid interference between the reinforcing member 4 and surrounding parts, which would affect the arrangement of body parts in the front engine compartment.

[0063] It is worth noting that, in specific implementations, besides ensuring that the cavity within the lower front bulkhead reinforcing beam 3 constitutes the aforementioned arrangement space Q, and thereby placing the reinforcing member 4 inside the lower front bulkhead reinforcing beam 3, in some embodiments, the reinforcing member 4 can also be placed outside the lower front bulkhead reinforcing beam 3. In this case, as a feasible implementation, for example, a downwardly or rearwardly recessed groove can be formed on the outer surface of the lower front bulkhead reinforcing beam 3, which forms the aforementioned arrangement space Q, and the reinforcing member 4 is placed within this groove.

[0064] It is understandable that the groove formed on the outer side of the lower front reinforcement beam 3 is recessed downwards, meaning the groove is specifically located at the top of the lower front reinforcement beam 3, and recessed backwards, meaning the groove is specifically located on the front side of the lower front reinforcement beam 3. Furthermore, when the reinforcement 4 is placed in the groove on the outer side of the lower front reinforcement beam 3, it can be fixed by conventional screwing or welding. If necessary, auxiliary connection structures such as connecting plates or connecting brackets can also be further provided to achieve a stable arrangement of the reinforcement 4 on the lower front reinforcement beam 3.

[0065] In this embodiment, it remains the same. Figures 2 to 5 and combined Figure 6 As shown, in some exemplary embodiments, the aforementioned reinforcing member 4 may be, for example, a tubular beam. Thus, by using a tubular beam for the reinforcing member 4, not only can the ease of fabrication of the tubular beam be utilized to facilitate the fabrication of the reinforcing member 4 and reduce its fabrication cost, but it can also utilize the high structural strength of the tubular beam to increase the structural strength of the reinforcing member 4, thereby enabling the reinforcing member 4 to have a better reinforcing effect.

[0066] It is worth noting that, based on the use of a tubular beam for reinforcement component 4, and further combined with... Figure 6 As shown, in some exemplary embodiments, preferably, for example, the cross-section of the reinforcing member 4 can be a closed structure. Thus, by further making the cross-section of the reinforcing member 4 a closed structure on the basis of using a tubular beam, the torsional and compressive resistance of the reinforcing member 4 can be further improved by utilizing the closed cross-section of the reinforcing member 4, which helps to increase the overall collision resistance of the reinforcing member 4.

[0067] Furthermore, while making the reinforcing member 4 a tube beam and specifically a closed section, it is worth noting that, in specific implementation, depending on the actual design needs, the cross-section of the reinforcing member 4 can be a circular closed structure, or in addition to a circular closed section, the reinforcing member 4 can also be an elliptical closed section, a square closed structure, a polygonal closed section, or other irregular closed sections, etc.

[0068] In this embodiment, it should also be noted that although the cross-section of the reinforcing member 4 should be a closed structure as described above, this does not mean that necessary process holes or other structures cannot be formed on the reinforcing member 4. However, in order to reduce the adverse effects on the structural performance of the reinforcing member 4, the number of process holes on the reinforcing member 4 should be minimized, and even, where circumstances permit, process holes or other structures on the reinforcing member 4 should be avoided altogether.

[0069] Furthermore, in specific implementations, the reinforcing member 4 in this embodiment is a tubular beam, which is an exemplary implementation; for example, it can also be a hot-expansion tube. Thus, by using a hot-expansion tube, it is also beneficial to achieve a lightweight reinforcing member 4 and to enable the reinforcing member 4 to have better structural strength.

[0070] In this embodiment, the following continues... Figures 3 to 6 As shown, in some exemplary embodiments, the reinforcing member 4 is disposed inside the lower front reinforcement beam 3. In specific implementations, for example, the reinforcing member 4 can be fixed inside the lower front reinforcement beam 3 by the first connecting bracket 5.

[0071] At this time, by fixing the reinforcing member 4 inside the lower front reinforcement beam 3 via the first connecting bracket 5, it is convenient to fix the reinforcing member 4 inside the lower front reinforcement beam 3, and it obviously also has the advantages of simple structure, easy design and implementation and low cost.

[0072] The reinforcement 4 is disposed within the front lower reinforcement beam 3 via the first connecting bracket 5. In some exemplary embodiments, preferably, for example, the first connecting bracket 5 may be configured as a plurality of such brackets spaced apart along the extension direction of the reinforcement 4.

[0073] Therefore, by setting the first connecting bracket 5 to be arranged in multiple spaced intervals along the extension direction of the reinforcing member 4, the stability of the reinforcing member 4 installed in the front lower reinforcing beam 3 can be guaranteed, so that the reinforcing member 4 and the front lower reinforcing beam 3 can fully exert the synergistic effect between the two, so as to better increase the structural strength of the front of the vehicle body and improve the collision response capability during vehicle collision.

[0074] It should be noted that, in specific implementation, the number of the first connecting brackets 5 can be selected according to the cross-sectional dimensions and length of the reinforcing member 4. Furthermore, in order to ensure the stability of the reinforcing member 4 within the front lower reinforcing beam 3 and to ensure that the reinforcing member 4 does not detach from the front lower reinforcing beam 3 during a vehicle collision and can bear the impact of the collision together with the front lower reinforcing beam 3, it is advisable to avoid designing too many first connecting brackets 3, which would be detrimental to the lightweighting of the vehicle body.

[0075] In this embodiment, it remains the same. Figure 4 and Figure 5As shown, the reinforcing member 4 is disposed within the lower front reinforcement beam 3 via the first connecting bracket 5. In some exemplary embodiments, for example, an installation space S may be formed between the first connecting bracket 5 and the lower front reinforcement beam 3, and the reinforcing member 4 is specifically fixed within the installation space S.

[0076] At this point, the first connecting bracket 5 and the lower front reinforcing beam 3 form an installation space S, and the reinforcing member 4 is fixed within this installation space S. This not only utilizes the constraint effect of the installation space S on the reinforcing member 4 to ensure the stability of the reinforcing member 4's position within the lower front reinforcing beam 3, but also allows the first connecting bracket 5 and the lower front reinforcing beam 3 to form a ring structure. Furthermore, the high strength of the ring structure increases the reliability of the connection between the reinforcing member 4 and the lower front reinforcing beam 3, which helps to further improve the stability of the reinforcing member 4 within the lower front reinforcing beam 3, as well as enhance the synergistic effect between the reinforcing member 4 and the lower front reinforcing beam 3.

[0077] In this embodiment, in some exemplary implementations, the following continues to be combined Figure 7 and Figure 8 As shown, structurally, the lower front bulkhead reinforcing beam 3 may include, for example, an upper reinforcing beam plate 301 and a lower reinforcing beam plate 302 connected below the upper reinforcing beam plate 301. The upper reinforcing beam plate 301, the lower reinforcing beam plate 302, and the front bulkhead plate 1 together form a cavity inside the lower front bulkhead reinforcing beam 3, and the first connecting bracket 5 is specifically connected between the upper reinforcing beam plate 301 and the lower reinforcing beam plate 302.

[0078] At this point, it is understandable that the front lower reinforcing beam 3 is mainly composed of an upper reinforcing beam plate 301 and a lower reinforcing beam plate 302. The upper reinforcing beam plate 301, the lower reinforcing beam plate 302, and the front bulkhead plate 1 together form the cavity inside the front lower reinforcing beam 3. The first connecting bracket 5 is connected between the upper reinforcing beam plate 301 and the lower reinforcing beam plate 302. This makes the structure of the front lower reinforcing beam 3 relatively simple and facilitates the formation of the cavity inside the front lower reinforcing beam 3. It also facilitates the connection between the first connecting bracket 5 and the front lower reinforcing beam 3.

[0079] In practical implementation, since the front lower reinforcing beam 3 is generally made of sheet metal, the aforementioned upper reinforcing beam plate 301 and lower reinforcing beam plate 302 can usually be formed by stamping. Furthermore, to increase the structural strength of the upper and lower reinforcing beam plates 301 and 302, reinforcing ribs can be added to both, or some shapes that facilitate structural strength improvement can be designed. In terms of specific connections, welding is typically used to achieve the connection between the upper and lower reinforcing beam plates 301 and 302, as well as between the upper and lower reinforcing beam plates 301 and the front bulkhead 1.

[0080] In this embodiment, the following continues... Figure 9 As shown, in some exemplary embodiments of the first connecting bracket 5, it may be a strip-shaped plate structure. When the reinforcing member 4 is installed in the front lower reinforcing beam 3, the middle part of the first connecting bracket 5 with the strip-shaped plate structure may be fixedly connected to the reinforcing member 4. Then, one end of the first connecting bracket 5 may be fixedly connected to the upper plate 301 of the reinforcing beam, and the other end may be fixedly connected to the lower plate 302 of the reinforcing beam. This not only realizes the indirect connection between the reinforcing member 4 and the front lower reinforcing beam 3, but also forms the above-mentioned installation space S between the first connecting bracket 5 and the front lower reinforcing beam 3.

[0081] In this embodiment, please continue to refer to... Figure 2 , Figure 4 and Figure 6 and combined Figure 11 As shown, in some exemplary embodiments, the reinforcement 4 can be connected to the longitudinal beams 2 of the front engine compartment on both sides, for example, via a second connecting bracket 6.

[0082] At this time, by connecting the reinforcing member 4 to the longitudinal beams 2 of the front engine compartment on both sides through the second connecting bracket 6, it is convenient to realize the connection between the reinforcing member 4 and the longitudinal beams 2 of the front engine compartment on both sides. It also has the advantages of simple structure and easy implementation. At the same time, it is also helpful to ensure the stability of the connection between the reinforcing member 4 and the longitudinal beams 2 of the front engine compartment.

[0083] In specific implementation, as an exemplary structural form of the second connecting bracket 6, it is combined with Figure 10 As shown, the second connecting bracket 6 can be, for example, a stamped sheet metal bracket structure, and the main structure of the second connecting bracket 6 can be a right-angled structure to facilitate connection with the reinforcing member 4. At the same time, a first connecting flange 601 is also provided on one side edge of the second connecting bracket 6, which is used to connect with the front engine compartment longitudinal beam 2.

[0084] Furthermore, it is worth noting that, in addition to connecting the reinforcing member 4 to the forward engine compartment longitudinal beams 2 on both sides via the second connecting brackets 6 located at its two ends, other embodiments may also connect the reinforcing member 4 directly or indirectly to the forward engine compartment longitudinal beams 2 in other ways. Specifically, since the reinforcing member 4 is a tubular beam, for example, a flange structure can be formed at the end of the reinforcing member 4, thereby directly connecting the reinforcing member 4 to the forward engine compartment longitudinal beam 2 via the flange structure at that end. Alternatively, conventional connecting bosses or other structures can be provided on the forward engine compartment longitudinal beam 2 to achieve the connection between the reinforcing member 4 and the forward engine compartment longitudinal beam 2.

[0085] In this embodiment, the reinforcement 4 is still connected to the longitudinal beams 2 of the front cabin on both sides through the second connecting bracket 6. In some exemplary embodiments, the second connecting bracket 6 may be further connected to the lower front reinforcement beam 3.

[0086] In this way, by connecting the second connecting bracket 6 to the lower front bulkhead reinforcing beam 3, the second connecting bracket 6 can connect the reinforcing member 4 to the front engine compartment longitudinal beam 2, while simultaneously connecting the reinforcing member 4 to the lower front bulkhead reinforcing beam 3. This not only saves some of the first connecting bracket 5, helping to reduce vehicle weight and material costs, but also increases the connection strength between the lower front bulkhead reinforcing beam 3, the reinforcing member 4, and the front engine compartment longitudinal beam 2, thereby improving the rigidity of the front of the vehicle body.

[0087] It is worth noting that the connection between the second connecting bracket 6 and the lower front reinforcement beam 3 still refers to... Figure 10 As shown, for example, a second connecting flange 602 can be provided on the second connecting bracket 6, and the second connecting bracket 6 can be connected to the front lower reinforcing beam 3 through the connection between the second connecting flange 602 and the reinforcing beam lower plate 302.

[0088] In this embodiment, the following continues... Figures 1 to 3 As shown, in some exemplary embodiments, a front bulkhead heat shield mounting bracket 7 may be provided on the top of the front bulkhead lower reinforcing beam 3, for example. The front bulkhead heat shield mounting bracket 7 is connected to the front nacelle longitudinal beams 2 on both sides, and the front side of the front bulkhead heat shield mounting bracket 7 also protrudes into the front nacelle.

[0089] At this time, by setting the aforementioned front bulkhead heat insulation plate mounting bracket 7 on the top of the front bulkhead lower reinforcing beam 3, and connecting the front bulkhead heat insulation plate mounting bracket 7 to the longitudinal beams 2 of the front engine compartment on both sides, and the front bulkhead heat insulation plate mounting bracket 7 also protruding into the front engine compartment, it is convenient to install and arrange the front bulkhead heat insulation plate. At the same time, by utilizing the connection between the front bulkhead heat insulation plate mounting bracket 7 and the longitudinal beams 2 of the front engine compartment on both sides, a lateral connection and support structure can be further added at the front bulkhead position, which can better increase the structural strength of the front of the vehicle body and improve the response to vehicle collisions.

[0090] Furthermore, by making the front bulkhead heat shield mounting bracket 7 protrude into the front engine compartment, it can be understood that, on the one hand, it can provide ample space for the front bulkhead heat shield, and on the other hand, it can also enable the front bulkhead heat shield mounting bracket 7 to have a certain crumple energy absorption capacity when the front engine compartment components move backward in the event of a vehicle collision, which is beneficial to reducing the collision impact caused by the rearward movement of the front engine compartment components.

[0091] It is worth noting that, in specific implementation, the aforementioned front bulkhead heat insulation plate mounting bracket 7 can also be made of stamped sheet metal, and it can also be connected to the front bulkhead lower reinforcing beam 3 and the front engine compartment longitudinal beams 2 on both sides by welding.

[0092] It is worth noting that, regarding the front structure of the vehicle body in this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 11 As shown, it may include, for example, a front bulkhead lower reinforcing beam 3 located at the bottom of the front bulkhead 1.

[0093] The lower front bulkhead reinforcing beam 3 connects the left and right front engine compartment longitudinal beams 2, and the internal cavity of the lower front bulkhead reinforcing beam 3 forms an arrangement space Q. A reinforcing member 4 is installed in this arrangement space Q, extending along the left and right direction of the vehicle, and is also connected to the front engine compartment longitudinal beams 2 on both sides.

[0094] The reinforcing member 4 is a tubular beam, and it is fixed within the lower front bulkhead reinforcing beam 3 by multiple spaced first connecting brackets 5. Simultaneously, both ends of the reinforcing member 4 are connected to the forward engine compartment longitudinal beams 2 on each side via second connecting brackets 6. These second connecting brackets 6 are connected not only to the forward engine compartment longitudinal beams 2 but also to the lower front bulkhead reinforcing beam 3. Furthermore, a mounting bracket 7 for the front bulkhead heat insulation plate, which connects to the forward engine compartment longitudinal beams 2 on both sides and protrudes into the forward engine compartment, can also be installed at the top of the lower front bulkhead reinforcing beam 3.

[0095] In the preferred embodiment of the above-mentioned front body structure, the specific configuration and arrangement of the front lower reinforcing beam 3, the reinforcing member 4, and each connecting bracket can still be referred to the description in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the front lower reinforcing beam 3, the reinforcing member 4, and each connecting bracket can also be referred to the description in the above-mentioned exemplary embodiments.

[0096] The front structure of the vehicle body in this embodiment adopts the above design. By setting a reinforcing member 4 at the lower reinforcing beam 3 of the front bulkhead, the reinforcing member 4 and the lower reinforcing beam 3 of the front bulkhead can work together to increase the structural strength and rigidity of the front bulkhead. In the event of a frontal collision, the reinforcing member 4 and the lower reinforcing beam 3 of the front bulkhead can also work together to prevent the components inside the front engine compartment from moving backward, reducing the compression of the passenger compartment and better protecting the occupants, which is conducive to further improving the collision safety of the vehicle.

[0097] A second aspect of this application provides a vehicle that includes the front body structure described in the first aspect embodiment above.

[0098] The vehicle in this embodiment, by setting the aforementioned front body structure, can increase the structural strength and rigidity of the front body section. In the event of a frontal collision, it can also prevent the components inside the front engine compartment from moving backward, reduce the compression of the passenger compartment, better protect the occupants, and thus improve the vehicle's collision safety.

[0099] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
