Description

Technical Field

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

[0002] With the rapid development of automotive safety performance, frontal collision tests, especially the 25% offset rigid barrier collision test, have become a focus of market and public attention. Currently, domestic and international automakers are rapidly developing new energy and hybrid vehicles. These models have increasingly higher requirements for configuration, space, and battery range, and their weight is also increasing, making it increasingly difficult to meet the testing requirements for small offset collision tests.

[0003] In small offset collision tests, the outer sheet metal of the longitudinal beam is often severely torn. Especially in the early stages of the collision test, the longitudinal beam directly transfers the collision energy to the door sill and A-pillar during the process of being squeezed by the barrier. The deformation and energy absorption of the longitudinal beam is insufficient, and the A-pillar eventually bends. Utility Model Content

[0004] The purpose of this application is to solve the aforementioned technical problems by providing a reinforced structure, front engine compartment assembly, and vehicle, thereby transferring the collision force of the connecting parts to the longitudinal beams. This allows the longitudinal beams to deform and absorb energy in the early stages of a collision test, thus improving the energy absorption effect of the longitudinal beams, reducing collision energy, and enhancing the performance of the front engine compartment assembly. To achieve the above objectives, the technical solution of this application is as follows:

[0005] In a first aspect, this application provides a reinforcing structure, including a connector, which is an arc-shaped hollow tube structure. One end of the connector is configured to be connected to the front end of a longitudinal beam, and the other end of the connector is configured to be connected to the front end of a side beam.

[0006] In one possible implementation, the reinforcing structure further includes a reinforcing component; the reinforcing component includes a first reinforcing member and a second reinforcing member, the first reinforcing member being connected to the longitudinal beam to form a first inner cavity, and the second reinforcing member being connected to the inner wall of the first inner cavity and to the connecting member.

[0007] In one possible implementation, the first reinforcing member includes a first reinforcing body and a second reinforcing body; the upper part of the first reinforcing body is connected to the longitudinal beam to form a first inner cavity, the lower part of the first reinforcing body extends out of the longitudinal beam, and the second reinforcing body is connected to the first reinforcing body and the longitudinal beam respectively.

[0008] In one possible implementation, the upper part of the second reinforcing body is disposed in the first inner cavity, the upper part of the second reinforcing body is connected to the inner wall of the first inner cavity, the lower part of the second reinforcing body extends out as a longitudinal beam, and the lower part of the second reinforcing body is connected to the lower part of the first reinforcing body to form a second inner cavity.

[0009] In one possible implementation, the first reinforcing body includes a first reinforcing part and a second reinforcing part; one end of the first reinforcing part along the first direction is connected to the second reinforcing member, the other end of the first reinforcing part along the first direction is connected to the second reinforcing part, the second reinforcing part and the first reinforcing part are connected to form an angle, and the second reinforcing part is connected to the longitudinal beam.

[0010] In one possible implementation, the first reinforcing body further includes an upper reinforcing part and a lower reinforcing part, which are respectively disposed at both ends of the first reinforcing part along the second direction. The upper reinforcing part is connected to the second reinforcing part and the longitudinal beam, and the lower reinforcing part is connected to the second reinforcing part, the second reinforcing member and the subframe.

[0011] In one possible implementation, the second reinforcement includes a first support portion and a second support portion connected together. The first support portion is located in a first inner cavity and is connected to the first reinforcement and the second reinforcement respectively. The second support portion extends along a second direction to the lower part of the longitudinal beam. The second reinforcement also includes a guide rib, which extends along a third direction on the first support portion until it abuts against the longitudinal beam, and / or the guide rib extends at the top of the second support portion until it abuts against the second reinforcement.

[0012] In one possible implementation, the second reinforcing member includes a first fixing body and a second fixing body disposed on the end face of the first fixing body. The first fixing body is connected to the first reinforcing member, and the second fixing body extends into the first inner cavity. The circumferential direction of the second fixing body is connected to the inner wall of the first inner cavity.

[0013] In one possible implementation, the reinforcing component further includes a third reinforcing member, which is disposed on the same end face as the first reinforcing member and clamps the connecting member relative to the first reinforcing member.

[0014] Secondly, this application provides a front nacelle assembly including the aforementioned reinforcing structure. The front nacelle assembly also includes a crash beam, which is connected to the front end of the longitudinal beam via a reinforcing component of the reinforcing structure.

[0015] Thirdly, this application provides a vehicle including the aforementioned reinforced structure or front engine compartment assembly.

[0016] Compared with existing technologies, the beneficial effects of this application on the reinforced structure, front engine compartment assembly, and vehicle are mainly reflected in:

[0017] In the early stages of a small offset collision, when the obstacle avoidance mechanism squeezes into the connector, the connector can transfer some of the collision force to the longitudinal beam, allowing the longitudinal beam to absorb energy in the early stages of the collision, thereby reducing the collision energy and reducing the amount of collision energy transferred to the sill and A-pillar. The connector can also transfer the pushing force of the sliding in the Y-axis direction to the side beam. The connector has a bidirectional force transmission path, effectively dispersing the collision force and improving the overall structural performance of the longitudinal beam and side beam.

[0040] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0041] Example 1

[0042] This embodiment provides a reinforcing structure applied to the longitudinal beam 8, which is a part of the vehicle structure. The longitudinal beam 8 can be the front longitudinal beam of the vehicle body or a part of the front engine compartment assembly.

[0043] like Figure 1As shown, the X-axis direction can be parallel to the length direction of the vehicle body and parallel to the ground; the Y-axis direction can be parallel to the width direction of the vehicle body and parallel to the ground; the Z-axis direction can be parallel to the height direction of the vehicle body and perpendicular to the ground. For example, a reinforcing structure is installed on the longitudinal beam 8, which helps to improve the structural strength of the longitudinal beam 8. The reinforcing structure can be installed at the front end of the longitudinal beam 8 along the X-axis direction. The front end of the longitudinal beam 8 is connected to the rear end of the anti-collision beam 95 through the reinforcing structure. The cross-section of the longitudinal beam 8 is approximately rectangular, but can also be circular or other shapes. Correspondingly, the cross-section of the anti-collision beam 95 is approximately rectangular, but can also be circular or other shapes.

[0044] A portion of the reinforcing structure is located between the longitudinal beam 8 and the anti-collision beam 95, while another portion is located between the longitudinal beam 8 and the body component. The body component can be a side beam 9, which is located outside the longitudinal beam 8. That is, the side beam 9 is closer to the external space of the body than the longitudinal beam 8. The reinforcing structure can improve the connection stability of the longitudinal beam 8, the anti-collision beam 95, and the side beam 9. At the same time, during the collision test, it can transfer the collision force between the longitudinal beam 8, the anti-collision beam 95, and the side beam 9, effectively absorbing the collision energy. The reinforcing structure is described in detail below.

[0045] like Figures 2-6 As shown, the reinforcing structure includes a connector 1 and a reinforcing component 2. The connector 1 is an arc-shaped hollow tube structure. One end of the connector 1 is configured to connect to the front end of the longitudinal beam 8, and the other end of the connector 1 is configured to connect to the front end of the side beam 9. Here, "front end" refers to the direction facing the front of the vehicle.

[0046] The reinforcing component 2 includes a first reinforcing member 21 and a second reinforcing member 22. The first reinforcing member 21 is connected to the longitudinal beam 8 to form a first inner cavity 24. The second reinforcing member 22 is connected to the inner wall of the first inner cavity 24 and to the connecting member 1.

[0047] The longitudinal beam 8 and the side beam 9 are both arranged along the X-axis direction. The longitudinal beam 8 and the side beam 9 can be arranged in parallel. The side beam 9 is located in the space above the longitudinal beam 8. The front end of the side beam 9 is located behind the front end of the longitudinal beam 8. When one end of the connector 1 is connected to the reinforcing component 2, that is, one end of the connector 1 is set close to the front end of the longitudinal beam 8, and the other end of the connector 1 is connected to the front end of the side beam 9. The connector 1 can extend in an arc from the Z-axis direction to the X-axis direction. The connector 1 can be located outside the longitudinal beam 8, that is, the connector 1 is closer to the external space of the vehicle than the longitudinal beam 8. During the small offset test, when the obstacle avoidance compresses the connecting piece 1, the connecting piece 1 can effectively transmit the pushing force of the sliding in the Y-axis direction. The collision force is transmitted to the body parts, namely the side beam 9, through the connecting piece 1. At the same time, the collision force is transmitted to the longitudinal beam 8 through the reinforcing component 2. This ensures that the sliding force of the vehicle in the Y-axis direction is increased as much as possible within a reasonable range, avoiding the direct transmission of the collision force to the door sill or A-pillar, which could cause injury to the occupants of the vehicle. It also keeps the vehicle in a relatively stable posture during the collision, avoiding excessive sideslip or rotation.

[0048] Connector 1 can be a hollow tube structure and integrally formed. Both ends of connector 1 are through-connected. Connector 1 is made of high-strength duplex steel (590DP). The cross-section of connector 1 can be circular, rectangular or other shapes, and its cross-sectional thickness is 2mm-2.2mm to ensure the bending strength and energy absorption effect of connector 1. It provides sufficient Y-axis support force in collision conditions and maintains effectiveness during obstacle avoidance. The appearance of connector 1 can be bent by bending equipment, avoiding the risk of collision separation and disintegration that is easy to occur when using multiple sheet metal parts spliced ​​together. This embodiment can effectively reduce the weight of connector 1 and reduce the complexity of the process. Connector 1 improves the connection between longitudinal beam 8 and side beam 9. The overall force transmission of connector 1 is continuous and complete, and the force transmission efficiency of connector 1 is higher.

[0049] The reinforcing component 2 includes a first reinforcing member 21 and a second reinforcing member 22. The first reinforcing member 21 is connected to the longitudinal beam 8 to form a first inner cavity 24. The second reinforcing member 22 is connected to the inner wall of the first inner cavity 24, increasing the contact area between the reinforcing component 2 and the longitudinal beam 8. The second reinforcing member 22 can enhance the structural strength and support performance of the first inner cavity 24. During collision tests, the collision force can be quickly and evenly transferred from the reinforcing component 2 to the longitudinal beam 8. The first inner cavity 24, formed by the reinforcing component 2, can directly absorb the collision energy, preventing all the collision energy from acting directly on the longitudinal beam 8. On the longitudinal beam 8, the deformation of the longitudinal beam 8 is reduced; at the same time, the connection between component 2 and connector 1 is strengthened. Through connector 1, the pushing force of sliding in the Y-axis direction can be transmitted to the side beam 9. Connector 1 has a bidirectional force transmission path, which effectively disperses the collision force. In the early stage of small offset collision, when the obstacle avoidance squeezes into connector 1, connector 1 can transfer part of the collision force to the longitudinal beam 8, allowing the longitudinal beam 8 to absorb energy in the early stage of the collision, thereby reducing the collision energy and reducing the transmission of collision energy to the sill and A-pillar, thus improving the overall structural performance of the longitudinal beam 8 and the side beam 9.

[0050] In one implementation, such as Figure 7 , Figure 8 As shown, the first reinforcing member 21 includes a first reinforcing body 26 and a second reinforcing body 27. The upper part of the first reinforcing body 26 is connected to the longitudinal beam 8 to form a first inner cavity 24, and the lower part of the first reinforcing body 26 extends out of the longitudinal beam 8. The second reinforcing body 27 is disposed between the first reinforcing body 26 and the longitudinal beam 8.

[0051] The first reinforcing body 26 is roughly in the shape of a groove along the Z-axis. The upper half of the first reinforcing body 26 is connected to the longitudinal beam 8, and the lower half of the first reinforcing body 26 extends to the bottom of the longitudinal beam 8. The lower part of the first reinforcing body 26 is used to install the subframe. The longitudinal beam 8 includes an inner longitudinal beam plate 81 and an outer longitudinal beam plate 82. The inner longitudinal beam plate 81 and the outer longitudinal beam plate 82 are connected to form a longitudinal beam cavity 83. The longitudinal beam cavity 83 can be connected to the first inner cavity 24 so that the first reinforcing body 26 and the longitudinal beam 8 form a through cavity structure, thereby improving the collision energy absorption effect of the longitudinal beam 8.

[0052] The second reinforcing body 27 is disposed between the first reinforcing body 26 and the longitudinal beam 8. The second reinforcing body 27 can be disposed to separate the first inner cavity 24 so that the first inner cavity 24 forms multiple sub-cavities, thereby improving the energy absorption effect of the first inner cavity 24. The second reinforcing body 27 can also be disposed against the inner wall of the first inner cavity 24 to strengthen the rigidity and support performance of the inner wall of the first inner cavity 24.

[0053] For example, the outer plate 82 of the longitudinal beam is the plate facing the external space of the longitudinal beam 8 towards the vehicle body, and the inner plate 81 of the longitudinal beam is the plate facing the internal space of the longitudinal beam 8 towards the vehicle body. The length of the outer plate 82 along the X-axis can be less than the length of the inner plate 81. Therefore, when the outer plate 82 and the inner plate 81 of the longitudinal beam are combined to form the longitudinal beam 8, a notch 84 with a shorter outer side and a longer inner side is formed at the front end of the longitudinal beam 8. The first reinforcing member 21 is connected to the longitudinal beam 8 to cover the position of the notch 84. The first reinforcing member 21 is connected to the longitudinal beam 8 to form a first inner cavity 24. The notch 84 is located in the first inner cavity 24. The second reinforcing member... When 22 extends into the first inner cavity 24, the notch 84 can avoid the second reinforcing member 22, allowing the second reinforcing member 22 to connect with the inner plate 81 of the longitudinal beam and / or the first reinforcing member 21. The position of the second reinforcing member 22 extending into the first inner cavity 24 is not affected by the space where the outer plate 82 of the longitudinal beam is located. The distance of the second reinforcing member 22 extending into the first inner cavity 24 is adapted to the length of the notch 84 along the X-axis. The second reinforcing member 22 can contact the inner wall of the first inner cavity 24 with the largest possible area, that is, contact the inner plate 81 of the longitudinal beam and the first reinforcing member 21, maintaining the supporting performance of the first inner cavity 24.

[0054] To further enhance the connection strength between the second reinforcing member 22 and the longitudinal beam 8, the first reinforcing member 26 and the outer plate 82 of the longitudinal beam have an overlapping area, so that part of the outer plate 82 of the longitudinal beam is placed in the first inner cavity 24. The second reinforcing member 22 can also extend into the inner cavity 83 of the longitudinal beam and / or extend between the outer plate 82 of the longitudinal beam and the first reinforcing member 21. The assembly method of the second reinforcing member 22 and the longitudinal beam 8 is more flexible and the installation stability is more reliable.

[0055] In one embodiment, the upper part of the second reinforcing body 27 is disposed in the first inner cavity 24, the upper part of the second reinforcing body 27 is connected to the inner wall of the first inner cavity 24, the lower part of the second reinforcing body 27 extends out as a longitudinal beam 8, and the lower part of the second reinforcing body 27 is connected to the lower part of the first reinforcing body 26 to form a second inner cavity 25.

[0056] The lower part of the second reinforcing body 27 is connected and fixed to the lower part of the first reinforcing body 26, which can be used to install the subframe to ensure the stability of the subframe installation. The second inner cavity 25 can further improve the collision energy absorption effect and effectively transfer the collision force to the subframe along the Z-axis direction.

[0057] For example, the upper part of the second reinforcing body 27 can be located between the first reinforcing body 26 and the outer plate 82 of the longitudinal beam, with the inner plate 81 of the longitudinal beam, the outer plate 82 of the longitudinal beam, the second reinforcing body 27 and the first reinforcing body 26 arranged sequentially along the Y-axis; the upper part of the second reinforcing body 27 can also be located between the first reinforcing body 26 and the inner plate 81 of the longitudinal beam, with the inner plate 81 of the longitudinal beam, the second reinforcing body 27, the outer plate 82 of the longitudinal beam and the first reinforcing body 26 arranged sequentially along the Y-axis; so that the upper part of the second reinforcing body 27 can be connected to the inner plate 81 of the longitudinal beam, or to the first reinforcing body 26, or to the outer plate 82 of the longitudinal beam, thereby improving the connection strength between the upper part of the second reinforcing body 27 and the inner wall of the first inner cavity 24; in this embodiment, the upper part of the second reinforcing body 27 is located between the first reinforcing body 26 and the outer plate 82 of the longitudinal beam, ensuring the connection strength of the first reinforcing body 26 and increasing the tear resistance of the outer plate 82 of the longitudinal beam.

[0058] In one implementation, such as Figure 9 , Figure 10 As shown, the first reinforcing member 21 includes a first reinforcing part 31 and a second reinforcing part 32; one end of the first reinforcing part 31 along the first direction is connected to the second reinforcing member 22, and the other end of the first reinforcing part 31 along the first direction is connected to the second reinforcing part 32; the second reinforcing part 32 is deflected relative to the first reinforcing part 31 and connected to the longitudinal beam 8.

[0059] The first reinforcing part 31 is parallel to the XZ plane, the first direction is parallel to the X-axis direction, the second direction is parallel to the Z-axis direction, and the perpendicular line of the first reinforcing part 31, i.e. the third direction, can be parallel to the Y-axis direction.

[0060] For example, one end of the first reinforcing part 31 along the first direction is connected to the second reinforcing member 22, which may be connected to the rear end of the second reinforcing member 22 along the X-axis direction. Specifically, the front end of the first reinforcing part 31 is provided with a first connecting edge 61, which may be perpendicular to the first reinforcing part 31. The first connecting edge 61 is connected to the rear end of the second reinforcing member 22 so that the first reinforcing part 31 and the second reinforcing member 22 are stably fixed.

[0061] The first reinforcing part 31 is connected to the second reinforcing part 32 at the other end along the first direction. It can be connected to the front end of the second reinforcing part 32 along the X-axis direction. The connection between the first reinforcing part 31 and the second reinforcing part 32 can be smoothly transitioned. The second reinforcing part 32 is deflected relative to the first reinforcing part 31. This can be understood as the second reinforcing part 32 and the first reinforcing part 31 forming an included angle β. The included angle β can be an obtuse angle. The second reinforcing part 32 is deflected relative to the first reinforcing part 31 toward the interior space of the vehicle body. The inner side of the second reinforcing part 32 is the deflection side, and the outer side of the second reinforcing part 32 is the deviation side.

[0062] The rear end of the second reinforcing part 32 is provided with a second connecting edge 62, which is connected to the outer plate 82 of the longitudinal beam. The second connecting edge 62 can be tightly abutted against the outer plate 82 of the longitudinal beam; specifically, the upper half of the second connecting edge 62 is connected to the outer plate 82 of the longitudinal beam, and the lower half of the second connecting edge 62 extends out of the outer plate 82 of the longitudinal beam along a second direction. The second connecting edge 62 is stably fixed to the outer plate 82 of the longitudinal beam, and can also provide a mounting point for the subframe.

[0063] For example, the first reinforcing part 31 includes a first reinforcing rib 63. The first reinforcing rib 63 can transmit force flow when it absorbs energy and deforms. The first reinforcing rib 63 extends along a first direction. For example, the first reinforcing rib 63 is formed into a height difference structure along a third direction. It can be understood that the first reinforcing part 31 can be divided by the first reinforcing rib 63 to form a plurality of first reinforcing regions 64. Adjacent first reinforcing regions 64 have a height difference along a third direction. Adjacent first reinforcing regions 64 are transitioned by the first reinforcing rib 63. The plurality of first reinforcing regions 64 can effectively absorb collision energy and can also improve the structural strength of the first reinforcing part 31. The front end of the first reinforcing rib 63 can extend to the first connecting edge 61, and the rear end of the first reinforcing rib 63 can extend to the second reinforcing part 32.

[0064] For example, the second reinforcing part 32 includes a second reinforcing rib 65, which is beneficial for guiding the deformation of the second reinforcing part 32 and also for reducing the moment. The second reinforcing rib 65 extends along the deflection direction of the second reinforcing part 32. For example, the second reinforcing part 32 can be divided by the second reinforcing rib 65 to form a plurality of second reinforcing regions 66. The second reinforcing rib 65 has the same structure as the first reinforcing rib 63, both of which are height difference structures. The plurality of second reinforcing regions 66 can effectively absorb collision energy and also improve the structural strength of the second reinforcing part 32. The front end of the second reinforcing rib 65 can extend to the first reinforcing part 31, and the rear end of the second reinforcing rib 65 can extend to the second connecting edge 62.

[0065] At least a portion of the second reinforcing rib 65 is projected in the first direction at a position offset from the first reinforcing rib 63. The first reinforcing rib 63 and the second reinforcing rib 65 can also be a continuous section of reinforcing ribs. In order to increase the torsional resistance at the connection between the first reinforcing part 31 and the second reinforcing part 32, the first reinforcing rib 63 and the second reinforcing rib 65 are relatively offset, effectively guiding the force flow to different of the aforementioned reinforcing areas. This helps the first reinforcing body 26 to deform stably, absorb energy, and transmit force flow to the longitudinal beam 8 when subjected to a collision. The first reinforcing area 64 and / or the second reinforcing area 66 have through holes, which on the one hand achieves the effect of weight reduction, and on the other hand facilitates the installation of components, thereby improving the functionality of the first reinforcing body 26.

[0066] In one embodiment, the first reinforcing member 21 further includes an upper reinforcing part 33 and a lower reinforcing part 34, which are respectively disposed at both ends of the first reinforcing part 31 along the second direction. The upper reinforcing part 33 is connected to the second reinforcing part 32 and the longitudinal beam 8, respectively, and the lower reinforcing part 34 is connected to the second reinforcing part 32, the second reinforcing member 22 and the subframe, respectively.

[0067] The upper reinforcing part 33 and the lower reinforcing part 34 can be parallel. One end of the upper reinforcing part 33 along the third direction is connected to the top of the first reinforcing part 31, and the other end of the upper reinforcing part 33 along the third direction is connected to the outer plate 82 of the longitudinal beam. Specifically, the other end of the upper reinforcing part 33 along the third direction is provided with a first fixed edge 71. The first fixed edge 71 is perpendicular to the upper reinforcing part 33. The upper reinforcing part 33 is connected to the outer plate 82 and the inner plate 81 of the longitudinal beam through the first fixed edge 71. The first fixed edge 71 is partially located at the notch 84 so that the first fixed edge 71, the outer plate 82 and the inner plate 81 of the longitudinal beam are stacked to ensure that the upper reinforcing part 33 is stably connected to the longitudinal beam 8.

[0068] For example, one end of the upper reinforcing part 33 along the first direction corresponds to the second reinforcing member 22, and the other end of the upper reinforcing part 33 along the first direction is provided with a second fixed edge 72. The second fixed edge 72 is connected to the bias side of the second reinforcing part 32, and the connection between the second fixed edge 72 and the upper reinforcing part 33 is a smooth transition, so that the first inner cavity 24 formed by the connection and enclosure of the first reinforcing part 31, the second reinforcing part 32 and the upper reinforcing part 33 is improved, which helps the collision energy absorption effect of the first reinforcing member 21.

[0069] For example, one end of the lower reinforcing portion 34 along the first direction is connected to the second reinforcing member 22. Specifically, the front end of the lower reinforcing portion 34 along the first direction is provided with a first supporting edge 73, which is perpendicular to the lower reinforcing portion 34 and connected to the second reinforcing member 22. The other end of the lower reinforcing portion 34 along the first direction is connected to the second reinforcing portion 32. Specifically, the rear end of the lower reinforcing portion 34 along the first direction is provided with a second supporting edge 74, which is perpendicular to the lower reinforcing portion 34 and the second supporting edge 74 is offset from the second reinforcing portion 32. Laterally connected; one end of the lower reinforcing part 34 along the third direction is connected to the bottom of the first reinforcing part 31, and the other end of the lower reinforcing part 34 along the third direction is provided with a third support edge 75, which is used to connect to the bottom of the second reinforcing body 27. The first reinforcing part 31, the lower reinforcing part 34, the second reinforcing part 32 and the second reinforcing body 27 are connected and enclosed to form a second inner cavity 25, which helps the collision energy absorption effect of the first reinforcing member 21, so that the collision force can be smoothly transferred from the first reinforcing member 21 to the subframe, and share a certain collision force with the longitudinal beam 8.

[0070] For example, such as Figure 11As shown, the second reinforcing body 27 is located between the first reinforcing body 26 and the longitudinal beam 8. The second reinforcing body 27 is connected to the first reinforcing body 26 and the second reinforcing member 22 respectively. Specifically, the second reinforcing body 27 includes a first support part 41 and a second support part 42. The first support part 41 is arranged along a first direction, and the second support part 42 is arranged along a second direction. The first support part 41 is part of the bottom wall of the first inner cavity 24. The front end of the first support part 41 along the first direction is provided with a first folded edge 43, which is connected to the second reinforcing member 22. The rear end of the first support part 41 along the first direction is provided with a second folded edge 44, which is connected to the bias side of the second reinforcing part 32. One end of the first support part 41 along the third direction is provided with a third folded edge 45, which is connected to the inner side of the first reinforcing part 31. The first support part 41 can enhance the molding strength of the first inner cavity 24 and further improve the connection stability between the first reinforcing member 21 and the longitudinal beam 8. When the collision test is conducted, the second reinforcing body 27 can transmit the collision force to multiple directions respectively, thereby improving the energy absorption effect.

[0071] For example, a portion of the second support portion 42 is located below the longitudinal beam 8. The front end of the second support portion 42 along the first direction is provided with a fourth folded edge 46, which is connected to the second reinforcing member 22. The first support edge 73, the first folded edge 43, and the fourth folded edge 46 are arranged in a triangular spatial arrangement and are all connected to the second reinforcing member 22, so that the first reinforcing member 21 and the second reinforcing member 22 maintain a sufficiently stable connection relationship and improve the rigidity of the reinforced structure. The rear end of the second support portion 42 along the first direction is provided with a third connecting edge 47. A portion of the second connecting edge 62, a portion of the third connecting edge 47, and the outer plate 82 of the longitudinal beam are stacked together, and the second support portion 42 effectively strengthens the connection relationship between the second reinforcing member 22 and the longitudinal beam 8. The bottom of the second support portion 42 is provided with a fifth folded edge 48, which is connected to the third support edge 75. The fifth folded edge 48 provides sufficient support force for the second support portion 42 so that the second inner cavity 25 can effectively absorb collision energy.

[0072] For example, the second reinforcing body 27 includes a guide rib 49. One section of the guide rib 49 extends along a third direction on the first support portion 41, and another section of the guide rib 49 extends in a bent manner on the second support portion 42. Specifically, the guide rib 49 extends from the top of the second support portion 42 to its front end and transitions to the fourth fold 46. The two sections of the guide rib 49 can be a continuous structure or arranged separately. The guide rib 49 abuts against the longitudinal beam 8 along a third direction from the first support portion 41, and extends from the top of the second support portion 42 to one end along a first direction and abuts against the second reinforcing member 22. This can effectively guide the force flow from the second reinforcing body 27 to the second reinforcing member 22 and the longitudinal beam 8. The guide rib 49 located in the second support portion 42 passes through a triangular space and does not produce instability, which helps to reduce the torque of the second reinforcing body 27. The guide ribs 49 located on the second support part 42 form multiple bends, which improve the bending resistance of the second support part 42 and have a good energy absorption effect. After the force flow is dispersed through the second support part 42, it is transmitted to the second reinforcing member 22 and the longitudinal beam 8, further reducing the probability of the longitudinal beam 8 absorbing energy and tearing.

[0073] For example, additional reinforcing ribs may be provided at the connection between the second reinforcing body 27 and each of the above-mentioned folded edges to improve the connection strength between the folded edges and the second reinforcing body 27 and reduce the risk of the folded edges tearing under stress.

[0074] In one implementation, such as Figure 12 As shown, the second reinforcing member 22 includes a first fixing body 51 and a second fixing body 52 disposed on the end face of the first fixing body 51. The first fixing body 51 is connected to the first reinforcing member 21, and the second fixing body 52 extends to the first inner cavity 24. The circumferential direction of the second fixing body 52 is connected to the inner wall of the first inner cavity 24.

[0075] The first fixing body 51 and the second fixing body 52 can be connected as one piece or as separate pieces. The first fixing body 51 is provided with an opening 53, which corresponds to the second fixing body 52. ​​The second fixing body 52 is arranged circumferentially along the opening, so that the second fixing body 52 can be easily fixed to the first inner cavity 24 through the opening 53.

[0076] For example, the second fixing body 52 can be in the form of a roughly square ring structure, and the inner plate 81 of the longitudinal beam can be in the form of a roughly C-shaped structure. The bottom wall of the second fixing body 52 is connected to the first support part 41 and the inner plate 81 of the longitudinal beam, respectively. The top wall of the second fixing body 52 is connected to the upper reinforcing part 33 and the inner plate 81 of the longitudinal beam, respectively. One side wall of the second fixing body 52 is connected to the first reinforcing part 31, and the other side wall of the second fixing body 52 is connected to the inner plate 81 of the longitudinal beam. The second fixing body 52 is easy to install in the first inner cavity 24 and has high structural strength.

[0077] In one embodiment, the reinforcing component 2 further includes a third reinforcing member 23, which and the first reinforcing member 21 are both disposed on the same end face of the second reinforcing member 22, and the third reinforcing member 23 and the first reinforcing member 21 clamp the connecting member 1 relative to each other.

[0078] The third reinforcing member 23 has an approximate L-shaped structure. One side of the third reinforcing member 23 is connected to the first fixing body 51, and the other side of the third reinforcing member 23 is connected to the connecting member 1. The connecting member 1 is stably clamped and positioned between the third reinforcing member 23 and the first reinforcing member 21. In the collision test, when the obstacle avoidance squeezes the connecting member 1, the connecting member 1 can transfer the collision force to the second reinforcing member 22 through the third reinforcing member 23, thereby improving the connection strength of the connecting member 1 and further ensuring the stable energy absorption effect of the connecting member 1.

[0079] For example, the connector 1 includes a force transmission rib 11, which is arranged along the extension direction of the connector 1. This helps to guide the force flow on the connector 1 and improve the structural strength and energy absorption effect of the connector 1.

[0080] Example 2

[0081] This embodiment provides a front engine compartment assembly, including the reinforcing structure described in the above embodiments. The front engine compartment assembly also includes a crash beam 95 and body components. The crash beam 95 is connected to the front end of the longitudinal beam 8 via a reinforcing component 2. The body components are located above the longitudinal beam 8 and are connected to the connecting member 1. The body components can be side beams 9, and the rear end of the side beams 9 can be connected to the front bulkhead (not shown in the figure) and the A-pillar (not shown in the figure).

[0082] The connector 1 extends in a roughly arc shape, with one end connected to the reinforcing component 2 and the other end connected to the side beam 9.

[0083] The side beam 9 includes an outer side beam plate 92 and an inner side beam plate 91. The outer side beam plate 92 and the inner side beam plate 91 are connected to form a side beam cavity 93. The end of the connector 1 extends into the side beam cavity 93 and is connected to the inner wall of the side beam cavity 93. Specifically, the connector 1 is connected to both the inner side beam plate 91 and the outer side beam plate 92. The connection method can be detachable or welded. The connector 1 can effectively solve the problem of poor connection performance between the front end of the longitudinal beam 8 and the side beam 9. During collision tests, it increases the deformation of the longitudinal beam 8 and provides effective vehicle slip-out force.

[0084] To further improve the stability of the connector 1, the connector 1 is connected to the longitudinal beam 8 through a wheel cover 94, and part of the wheel cover 94 is connected to the inner plate 91 of the side beam.
