Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a door and a vehicle equipped with it. Background Technology

[0002] When a vehicle is involved in an accident, especially a rollover accident where the roof hits the ground or a roof crush accident where the roof is crushed by a heavy object, the vehicle's ability to cope with the collision under these conditions (i.e., roof crush conditions) has a significant impact on the safety of the occupants.

[0003] Taking vehicles with butterfly doors as an example, in roof crush tests, the barrier typically comes into contact with the door, making the door one of the main force-transmitting structures during a collision. However, existing butterfly doors still have shortcomings such as limited upper structural strength, which can affect the force transmission effect during roof crush tests and thus hinder the improvement of vehicle collision safety. Utility Model Content

[0004] In view of this, this application aims to provide a vehicle door that can improve the collision safety of a vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A car door includes a door body and a reinforcing member disposed on the door body; The top of the door body has a bent portion that bends to one side, and when the door is closed, the bent portion is located at the top of the vehicle. The reinforcing member includes a reinforcing member body located at the bend, and a first reinforcing arm connected at one end to the reinforcing member body, with the other end of the first reinforcing arm extending downward along the window frame structure in the door body.

[0006] Furthermore, the window frame structure includes a front frame located on the front side of the door body, and the first reinforcing arm extends obliquely downward along the front frame.

[0007] Furthermore, the window frame structure includes a rear frame located behind the door body, and the reinforcing member includes a second reinforcing arm with one end connected to the main body of the reinforcing member; The other end of the second reinforcing arm extends downward along the rear frame.

[0008] Furthermore, the reinforcing member includes a third reinforcing arm; The third reinforcing arm is connected between the bottom end of the first reinforcing arm and the bottom end of the second reinforcing arm, and the main body of the reinforcing member, the first reinforcing arm, the second reinforcing arm and the third reinforcing arm are connected to form a ring structure surrounding the window inside the window frame structure.

[0009] Furthermore, the main body of the reinforcing member is provided with hollow holes, and the main body of the reinforcing member has a ring structure; and / or, The reinforcing component is integrally molded.

[0010] Furthermore, the door body includes a connected inner door panel and an outer door panel; The reinforcing member is located between the inner door panel and the outer door panel, and the reinforcing member is connected to the inner door panel.

[0011] Compared with related technologies, this application has the following advantages: (1) The car door described in this application provides a reinforcing member on the car door body, and the reinforcing member includes a reinforcing member body located at the top bend of the car door and a first reinforcing arm extending downward along the window frame structure in the car door body. This not only increases the structural strength of the upper part of the car door by using the reinforcing member, especially the reinforcing member body located at the bend, but also improves the transmission effect of collision force in the roof pressure condition by using the first reinforcing arm extending downward, thereby improving the collision safety of the vehicle.

[0012] (2) The first reinforcing arm extends obliquely downward along the front frame of the window frame structure, which not only facilitates the transfer of the collision force to the lower front body frame structure, but also utilizes the support force provided by the lower front body frame structure to the first reinforcing arm, thereby improving the overall top pressure resistance of the reinforcing component and helping to improve the safety of the roof under pressure conditions.

[0013] (3) The reinforcement includes a second reinforcing arm that extends downward along the rear frame in the window frame structure, which can further increase the structural strength of the upper part of the door, improve the door's pressure-bearing capacity in the top pressure condition, and also increase the force transmission channel of the reinforcement in the roof pressure condition, which can improve the transmission and dispersion effect of the collision force and help improve the safety of the roof pressure condition.

[0014] (4) The reinforcement includes a third reinforcement arm connected between the bottom ends of the first reinforcement arm and the second reinforcement arm, and the three reinforcement arms and the main body of the reinforcement are connected together to form a ring structure around the window on the door body. The third reinforcement arm can be used to increase the structural strength of the upper part of the door and improve the door's pressure resistance under top pressure conditions. At the same time, the connecting effect of the third reinforcement arm can be used to better transmit and disperse the collision force, which helps to improve the safety of the roof under pressure conditions.

[0015] (5) By setting hollow holes on the main body of the reinforcing member, the main body of the reinforcing member is made into a ring structure. Not only can the weight of the main body of the reinforcing member be reduced by setting hollow holes, which is conducive to realizing the lightweight design of the reinforcing member, but at the same time, the structural strength of the main body of the reinforcing member can be guaranteed by taking advantage of the high strength of the ring structure on the basis of achieving lightweight, which is conducive to improving the quality of use of the reinforcing member.

[0016] This integrated molding of the reinforcement not only facilitates its fabrication and reduces design and manufacturing costs, but also ensures the reliability of the connection between the reinforcement arm and the main body of the reinforcement. This helps to guarantee the reinforcement's effect on the door and its ability to transmit impact forces.

[0017] (6) The reinforcement is located between the inner panel and the outer panel of the door, and the reinforcement is connected to the inner panel of the door. This facilitates the arrangement of the reinforcement on the door body and also avoids affecting the design and preparation of the outer panel of the door with the outer surface of the door, while achieving reinforcement of the upper part of the door. This helps to reduce the design and preparation cost of the door when reinforcement is provided.

[0018] Another object of this application is to provide a vehicle having doors in its body as described in any of the preceding claims.

[0019] Furthermore, the vehicle body has a rear enclosure that encloses the rear of the passenger compartment, and the side of the rear enclosure facing away from the passenger compartment forms a fuel tank mounting area and / or a battery pack mounting area, and the rear enclosure is provided with a rear enclosure reinforcement structure.

[0020] Furthermore, a forward-protruding central channel rear section is formed in the middle of the rear perimeter; The rear reinforcement structure includes reinforcing beams on the left and right sides of the rear section of the central channel, and both reinforcing beams are in a "Z" shape.

[0021] Furthermore, the reinforcing beams on both sides are arranged symmetrically about the rear section of the central channel; and / or, The rear enclosure is made of carbon fiber, and the reinforcing beams on both sides are formed by locally thickening the rear enclosure.

[0022] The vehicle described in this application, by providing the aforementioned door, can increase the structural strength of the upper part of the door and improve the transmission effect of collision force in the case of roof compression, which is beneficial to improving the collision safety of the vehicle.

[0023] Furthermore, by adding a rear reinforcement structure to the rear enclosure, which forms the fuel tank mounting area and the battery pack mounting area on one side of the rear enclosure, the structural strength of the rear enclosure can be increased, and the rear enclosure's ability to cope with vehicle collisions, especially side collisions, can be improved. This helps to enhance the safety of the fuel tank in the fuel tank mounting area and the battery pack in the battery pack mounting area on one side of the rear enclosure.

[0024] Secondly, the rear reinforcement structure includes reinforcing beams located on both sides of the rear section of the central tunnel, and the two reinforcing beams are arranged in a "Z" shape. This not only strengthens the structure of the rear section on both sides of the central tunnel through the "Z" shaped reinforcing beams, but also forms multiple interconnected collision force transmission channels in the rear section by utilizing the multiple beams connected in the "Z" shaped reinforcing beams. This can improve the transmission and dispersion of side collision force, help improve the rear section's collision response capability in the event of a side collision, and improve the safety of the fuel tank and battery pack on one side of the rear section.

[0025] Furthermore, the symmetrical arrangement of the side reinforcement beams with respect to the rear section of the central tunnel facilitates the design and molding of the side reinforcement beams and helps ensure the overall structural balance of the vehicle body. With the rear fascia made of carbon fiber, the side reinforcement beams are formed by locally thickening the rear fascia. This utilizes the carbon fiber material to ensure the overall structural strength of the rear fascia and helps reduce its weight, contributing to a lightweight vehicle design. Additionally, the locally thickened rear fascia facilitates the placement of the reinforcement beams and ensures their stability. Attached Figure Description

[0027] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. 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.

[0032] 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.

[0033] An embodiment of the first aspect of this application provides a car door, which is generally used in high-performance vehicles with a low and streamlined body. Through its innovative structural design, the car door can increase the structural strength of the upper part of the door and improve the transmission effect of collision force in the case of roof crushing, which is beneficial to improving the collision safety of the vehicle.

[0034] In related technologies, the ability of the vehicle's roof to withstand collisions (i.e., roof compression conditions) when a vehicle experiences a rollover accident with the roof hitting the ground or a roof crushing accident with the roof being crushed by a heavy object has a significant impact on the safety of the occupants.

[0035] At this point, for vehicles with butterfly doors or similar features where part of the door is located on the roof when the doors are closed, the barrier will generally come into contact with the door during roof crush conditions. This makes the door one of the main structures that absorbs the barrier impact and transmits the collision force during a collision.

[0036] However, existing butterfly doors still have shortcomings in their design, such as limited strength of the upper structure. This not only affects the door's resistance to pressure during roof crushing conditions, but also affects the door's ability to transmit and disperse collision forces, thus limiting the protective function the door can provide and hindering the improvement of vehicle collision safety.

[0037] In view of this, in order to overcome the shortcomings of the related technology, the door of this embodiment combines... Figures 1 to 7 As shown, the overall design includes a door body 1 and a reinforcing member 2 installed on the door body 1.

[0038] The door body 1 has a bent portion 111 at the top that bends to one side, and when the door is closed, the bent portion 111 is located at the top of the vehicle. The reinforcement 2 includes a reinforcement body 21 located at the bent portion 111, and a first reinforcement arm 22 connected at one end to the reinforcement body 21, and the other end of the first reinforcement arm 22 extends downward along the window frame structure 112 in the door body 1.

[0039] Therefore, as described above, by providing a reinforcing member 2 on the door body 1, and making the reinforcing member 2 include a reinforcing member body 21 located at the top bend 111 of the door, and a first reinforcing arm 22 extending downward along the window frame structure 112 in the door body 1, this embodiment can increase the structural strength of the upper part of the door by utilizing the reinforcing member 2, especially the reinforcing member body 21 located at the bend 111. At the same time, the first reinforcing arm 22 extending downward can improve the transmission effect of collision force in the roof pressure condition, thereby achieving the effect of improving vehicle collision safety.

[0040] Based on the above general introduction, specifically, the bending portion 111 located at the top of the door body 1 and at the top of the vehicle when the door is closed makes the door of this embodiment a butterfly door, and this embodiment will be specifically described with the door being a butterfly door as an example.

[0041] However, it is worth noting that the door in this embodiment is not limited to butterfly doors. Other door types with a bend 111 at the top and the bend 111 located on the top of the vehicle when the door is closed are also suitable for adopting the relevant design in this embodiment.

[0042] In this embodiment, in some exemplary implementations, the door body 1 also specifically includes a connected inner door panel 11 and an outer door panel (not shown in the figure), and the reinforcing member 2 is located between the inner door panel 11 and the outer door panel, and the reinforcing member 2 is also connected to the inner door panel 11.

[0043] In this way, the reinforcing member 2 is located between the inner door panel 11 and the outer door panel, and the reinforcing member 2 is connected to the inner door panel 11. It can be understood that this facilitates the arrangement of the reinforcing member 2 on the door body 1, and at the same time, it can achieve the reinforcement of the upper part of the door while avoiding the impact on the design and manufacturing of the outer door panel used to form the exterior surface of the door. This helps to reduce the overall design and manufacturing cost of the door when the reinforcing member 2 is set.

[0044] Continue to combine Figures 1 to 3 As shown in this embodiment, based on the reinforcement 2 being connected to the inner panel 11 of the door, taking the relevant structure on the inner panel 11 of the door as an example, in some exemplary embodiments, the window frame structure 112 in the door body 1 includes a front frame 1121 located on the front side of the door body 1, and the aforementioned first reinforcement arm 22 extends obliquely downward along the front frame 1121.

[0045] At this point, by extending the first reinforcing arm 22 diagonally downward along the front frame 1121 of the window frame structure 112, it can be understood that, given that vehicles with butterfly doors are usually two-door structures, that is, only two doors on the left and right, and the front side of each door is the body frame structure in the front engine compartment, extending the first reinforcing arm 22 diagonally downward along the front frame 1121 not only helps to transfer the collision force to the lower front body frame structure to achieve effective decomposition of the collision force, but also utilizes the support force provided by the lower front body frame structure to the first reinforcing arm 22 to improve the overall top pressure resistance of the reinforcing member 2, thus helping to improve the safety of the roof under pressure conditions.

[0046] In specific implementation, it is worth noting that the bottom end of the first reinforcing arm 22, which extends diagonally downward along the front frame 1121, can generally extend to the triangular window area in the door. This ensures effective connection between the first reinforcing arm 22 and the body frame structure in front of the door, thereby improving the setting effect of the first reinforcing arm 22.

[0047] In this embodiment, as follows... Figure 4 and Figure 5 As shown, in some exemplary embodiments, the window frame structure 112 on the door body 1 also includes a rear frame 1122 located at the rear of the door body 1, and the aforementioned reinforcement 2 also includes a second reinforcement arm 23 with one end connected to the reinforcement body 21, and the other end of the second reinforcement arm 23 extends downward along the rear frame 1122.

[0048] At this point, the reinforcing member 2 further includes a second reinforcing arm 23 extending downward along the rear frame 1122 in the window frame structure 112. Obviously, this embodiment can further increase the structural strength of the upper part of the door and improve the door's pressure-bearing capacity under roof pressure conditions. At the same time, the second reinforcing arm on the rear side can increase the force transmission channel of the reinforcing member 2 under roof pressure conditions, which can improve the transmission and dispersion effect of collision force, and also help to improve the safety of roof pressure conditions.

[0049] Continue as Figure 6 and Figure 7 As shown, in some exemplary embodiments, the reinforcement 2 of this embodiment may further include, for example, a third reinforcing arm 24.

[0050] The third reinforcing arm 24 is connected between the bottom end of the first reinforcing arm 22 and the bottom end of the second reinforcing arm 23. Based on the arrangement of the third reinforcing arm 24, the above reinforcing body 21, the first reinforcing arm 22, the second reinforcing arm 23 and the third reinforcing arm 24 are also connected together to form a ring structure surrounding the window 100 inside the window frame structure 112.

[0051] Therefore, it can be understood that by including a third reinforcing arm 24 between the bottom ends of the first reinforcing arm 22 and the second reinforcing arm 23, and by connecting the three reinforcing arms and the main body 21 of the reinforcing member together to form an annular structure surrounding the window 100 on the door body 1, this embodiment can better increase the structural strength of the upper part of the door and improve the door's pressure-bearing capacity under top pressure conditions by utilizing the arrangement of the third reinforcing arm 24, especially by utilizing the annular structure formed by the connection of the three reinforcing arms and the main body 21 of the reinforcing member.

[0052] At the same time, this embodiment can obviously utilize the connecting effect of the third reinforcing arm 24 to increase the lateral force transmission channel between the first reinforcing arm 22 and the second reinforcing arm 23, so that the collision force can be better transmitted and dispersed, thereby helping to further improve the safety of the roof under pressure conditions.

[0053] In practical implementation, the aforementioned connecting reinforcing member body 21, first reinforcing arm 22, second reinforcing arm 23, and third reinforcing arm 24 forming a ring structure also form a through hole 2b on the reinforcing member 2. When the reinforcing member 2 is installed on the door body 1, the through hole 2b is correspondingly positioned to correspond to the window 100 on the door body 1, thereby enabling the ring structure formed by the connection of each reinforcing arm and the reinforcing member body 21 to reinforce the position of the window 100 in the door.

[0054] In this embodiment, we still combine Figures 1 to 7 As shown, in some exemplary embodiments, the reinforcing body 21 may be provided with a perforated hole 2a, and based on the perforated hole 2a, the reinforcing body 21 is made to have a ring structure.

[0055] In this way, by providing a perforated hole 2a on the main body 21 of the reinforcing member, thereby making the main body 21 of the reinforcing member have a ring structure, not only can the weight of the main body 21 of the reinforcing member be reduced by utilizing the perforated hole 2a, thus facilitating the lightweight design of the reinforcing member. Of course, it is understandable that by making the main body 21 of the reinforcing member have a ring structure, it is also possible to ensure the structural strength of the main body 21 of the reinforcing member by utilizing the high strength of the ring structure, which is conducive to improving the quality of use of the reinforcing member 2.

[0056] In this embodiment, in some exemplary implementations, the reinforcing member 2 can be integrally molded. In this case, making the reinforcing member 2 integrally molded not only facilitates the preparation of the reinforcing member 2 and reduces the design and preparation costs of the reinforcing member 2, but also obviously ensures the reliability of the connection between the reinforcing arm and the main body 21 of the reinforcing member, which helps to ensure the reinforcing effect of the reinforcing member 2 on the door and ensure the impact force transmission capability of the reinforcing member 2.

[0057] In specific implementation, for the one-piece reinforced part 2, for example, the reinforced part 2 can be made of steel or aluminum sheet metal and formed by stamping. At the same time, in terms of installation, the one-piece reinforced part 2 can generally be fixed to the inner panel 11 of the door by welding.

[0058] However, besides being a stamped sheet metal part, it is also possible to make the reinforcing member 2 of this embodiment using other materials. For example, when the door body 1 of this embodiment is made of carbon fiber, the reinforcing member 2 can also be made of carbon fiber.

[0059] It is worth noting that, regarding the car door in this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still made of... Figures 1 to 7 As shown, it may include, for example, a door body 1 and a reinforcing member 2 provided on the door body 1.

[0060] The top of the door body 1 has a bent portion 111 that bends to one side, and when the door is closed, the bent portion 111 is located on the top of the vehicle.

[0061] The reinforcing member 2 includes a reinforcing member body 21 and a reinforcing arm. The reinforcing member body 21 is located at the bending portion 111. Optionally, the reinforcing arm may include only the first reinforcing arm 22, or the reinforcing arm may include both the first reinforcing arm 22 and the second reinforcing arm 23, or the reinforcing arm may include the first reinforcing arm 22, the second reinforcing arm 23 and the third reinforcing arm 24.

[0062] One end of the first reinforcing arm 22 is connected to the reinforcing body 21, and the other end of the first reinforcing arm 22 extends diagonally downward along the front frame 1121 of the window frame structure 112 of the door body 1. One end of the second reinforcing arm 23 is connected to the reinforcing body 21, and the other end of the second reinforcing arm 23 extends downward along the rear frame 1122 of the window frame structure 112. The third reinforcing arm 24 is connected between the bottom end of the first reinforcing arm 22 and the bottom end of the second reinforcing arm 23, and the reinforcing body 21, the first reinforcing arm 22, the second reinforcing arm 23 and the third reinforcing arm 24 are also connected to form a ring structure surrounding the window 100 inside the window frame structure 112.

[0063] In addition, a hollow hole 2a is also provided on the main body 21 of the reinforcing member, making the main body 21 of the reinforcing member have a ring structure. At the same time, the reinforcing member 2 is integrally formed, and the reinforcing member 2 is located between the inner panel 11 and the outer panel of the door in the door body 1, and is specifically connected to the inner panel 11 of the door.

[0064] In the preferred embodiment of the car door described above, the specific configuration and arrangement of the car door body 1 and the reinforcing member 2, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the car door body 1 and the reinforcing member 2, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0065] The door in this embodiment adopts the above design, which can increase the structural strength of the upper part of the door, such as butterfly doors, and improve the door's ability to transmit collision force in the case of roof pressure resistance, thus improving the vehicle's collision safety and having good practicality.

[0066] An embodiment of the second aspect of this application provides a vehicle, the vehicle body of which is provided with a door as described in the first aspect embodiment above.

[0067] It is worth noting that, based on the use of the doors described above, the vehicle in this embodiment can generally be a high-performance model with a low and streamlined body, and preferably, for example, it can be a high-performance model with a low and streamlined body that uses butterfly doors.

[0068] In addition, continue as Figure 8 and Figure 9 As shown, in some exemplary embodiments, the vehicle based on this embodiment is a high-performance model with a low and streamlined body. The vehicle body also has a rear enclosure 3 that encloses the rear of the passenger compartment. A fuel tank mounting area S and a battery pack mounting area Q are formed on the side of the rear enclosure 3 that is away from the passenger compartment. At the same time, a rear enclosure reinforcement structure 32 is also provided on the rear enclosure 3.

[0069] It is understandable that, based on the formation of the fuel tank mounting area S and the battery pack mounting area Q on one side of the rear enclosure 3, by setting the rear enclosure reinforcement structure 32 on the rear enclosure 3, it can obviously increase the structural strength of the rear enclosure 3, improve the rear enclosure 3's ability to cope with vehicle collisions, especially side collisions, and thus help improve the safety of the fuel tank in the fuel tank mounting area S and the battery pack in the battery pack mounting area Q on one side of the rear enclosure 3.

[0070] In specific implementation, it is worth noting that on the side of the rear enclosure 3 facing away from the driver's compartment, in addition to forming a fuel tank mounting area S for installing the fuel tank and a battery pack mounting area Q for arranging the battery pack, it is also possible to have only a fuel tank mounting area S for installing the fuel tank or a battery pack mounting area Q for arranging the battery pack on one side of the rear enclosure 3. This embodiment does not limit this.

[0071] In addition, in practical implementation, the fuel tank in the fuel tank installation area S can generally be fixed to one side of the rear bulkhead 3 with steel straps, just like the fuel tanks in existing vehicles. The battery pack in the battery pack installation area Q can be connected to the rear bulkhead 3 and the longitudinal beams of the vehicle body using conventional structures such as bolts.

[0072] See also Figure 8 and Figure 9 As shown, in some exemplary embodiments, the rear enclosure 3 of this embodiment also has a forward-protruding central channel rear section 31 in the middle, which communicates with the central channel at the front floor of the vehicle body to provide a channel for the arrangement of vehicle pipelines, etc. Based on the above-mentioned central channel rear section 31, the rear enclosure reinforcement structure 32 specifically includes reinforcement beams 321 respectively provided on the left and right sides of the central channel rear section 31, and both sides of the reinforcement beams 321 are also Z-shaped.

[0073] At this point, by including reinforcing beams 321 on both sides of the rear section 31 of the central tunnel in the rear reinforcement structure 32, and making the reinforcing beams 321 in a "Z" shape, it can be understood that it can not only strengthen the structure of the rear section 3 on both sides of the central tunnel rear section 31 through the "Z" shaped reinforcing beams 321, but also obviously utilize the multiple beams connected in the "Z" shaped reinforcing beams 321 to form multiple interconnected collision force transmission channels at the rear section 3, which can improve the transmission and dispersion effect of side collision force, thereby helping to improve the collision response capability of the rear section 3 in the event of a vehicle side collision, and is beneficial to improving the safety of the fuel tank and battery pack on one side of the rear section 3.

[0074] Specifically, the beam structures of the aforementioned Z-shaped reinforcing beams 321 include a first beam 3211, a second beam 3212, and a third beam 3213, which are connected end-to-end to form a Z-shaped structure. Furthermore, in the event of a vehicle collision, especially a side collision, reference... Figure 9As shown, the side impact force can be transmitted and dispersed to the other side along the first beam 3211, the second beam 3212, and the third beam 3213, respectively, to achieve the transmission and dissipation of the impact force. At the same time, the end where the first beam 3211 and the second beam 3212 are connected, and the end of the third beam 3213 near the outside of the vehicle, can also strengthen the protection of the main impact points of the fuel tank and battery pack during a side impact, thereby reducing the force on the fuel tank and battery pack and improving their safety.

[0075] In this embodiment, in some exemplary implementations, the following continues... Figure 9 As shown, the two side reinforcing beams 321 can be arranged symmetrically about the rear section 31 of the central tunnel. This symmetrical arrangement of the two side reinforcing beams 321 about the rear section of the central tunnel facilitates the design and forming of the two side reinforcing beams 321 and also helps to ensure the overall balance of the vehicle body structure.

[0076] Furthermore, in some exemplary embodiments, the rear enclosure 3 of this embodiment may be made of carbon fiber, and based on this, the reinforcing beams 321 on both sides are also formed by locally thickening the rear enclosure 3.

[0077] Understandably, with the rear bulkhead 3 made of carbon fiber, the side reinforcing beams 321 are formed by locally thickening the rear bulkhead 3. On the one hand, the carbon fiber material can be used to ensure the overall structural strength of the rear bulkhead 3 and help reduce the weight of the rear bulkhead 3, which is conducive to the lightweight design of the vehicle body. On the other hand, the local thickening of the rear bulkhead 3 can facilitate the installation of the reinforcing beams 321 on the rear bulkhead and help ensure the stability of the reinforcing beams 321 installed on the rear bulkhead 3.

[0078] It is worth noting that, in specific implementations, besides using carbon fiber for the rear enclosure 3 and the reinforcing beam 321 constituting the rear enclosure reinforcement structure 32, it is also possible to use other materials for the rear enclosure 3 and the reinforcing beam 321 in other embodiments. For example, the rear enclosure 3 and the reinforcing beam 321 can be made of stamped steel sheet metal, and the reinforcing beam 321 can be welded to the rear enclosure 3. Alternatively, the rear enclosure 3 can be made of die-cast aluminum alloy, with the reinforcing beam 321 integrally formed on the rear enclosure 3 during casting.

[0079] The vehicle in this embodiment, by setting the aforementioned door, can increase the structural strength of the upper part of the door and improve the transmission effect of collision force in the case of roof pressure resistance, which is beneficial to improving the collision safety of the vehicle. At the same time, by setting the rear reinforcement structure 32 on the rear side, it can also improve the safety of the fuel tank in the fuel tank installation area S and the battery pack in the battery pack installation area Q on the rear side, thus having good practicality.

[0080] 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.
