Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a vehicle hood assembly and the vehicle itself. Background Technology

[0002] In related technologies, engine hoods are typically square, and buffer devices for such hoods are usually positioned near the edges, providing a crumple zone of about 55mm. However, these buffer devices are unsuitable for new engine hoods. These new hoods are small in the longitudinal direction but large in the transverse direction, with the transverse dimension being six times the longitudinal dimension. If the buffer devices in these technologies are installed at the edges, they will inevitably fail to support the central portion of the hood, which requires a larger crumple zone, and traditional buffer devices cannot provide sufficient crumple space. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a vehicle hood assembly that increases the crumple zone and adapts to a new type of engine hood.

[0004] According to an embodiment of the present invention, a vehicle hood assembly includes: an engine hood, a structural member below the engine hood; and a buffer bracket having a bracket body and a bracket connecting portion, the bracket connecting portion being connected to the engine hood, the bracket body being capable of cooperating with the structural member so that, in the event of a collision with the engine hood, the bracket body can slide longitudinally along the surface of the structural member under the guidance of the structural member.

[0005] According to an embodiment of the present invention, the vehicle is configured to slide longitudinally in the vehicle when the hood is involved in a collision, thereby increasing the longitudinal crumple zone compared to the vertical crumple zone in related technologies, thus increasing the crumple space and adapting to the new type of hood.

[0006] In some embodiments, the bracket body includes: a first bracket, one end of which is connected to the bracket connecting portion, and the other end of which abuts against the structural member and can slide longitudinally along the surface of the structural member under the guidance of the structural member; and a second bracket, one end of which is connected to the bracket connecting portion, and the other end of which is connected to the first bracket and can move under the drive of the first bracket.

[0007] In some embodiments, the bracket body includes: a first bracket and a second bracket, both of which are connected to the bracket connecting portion; and a third bracket, which abuts against the structural member, and whose two ends are respectively connected to the ends of the first bracket and the second bracket away from the bracket connecting portion; wherein the third bracket is capable of sliding longitudinally along the surface of the structural member under the guidance of the structural member.

[0008] In some embodiments, the third support is in surface contact with the surface of the structural member.

[0009] In some embodiments, the first bracket and the surface of the structural member have a set angle, the set angle being less than 90 degrees.

[0010] In some embodiments, the surface of the structural member is parallel to a horizontal plane.

[0011] In some embodiments, the second support has an induction portion to induce the second support to bend along the induction portion.

[0012] In some embodiments, the structural component includes a bracket support mounted on the front-end module of the vehicle.

[0013] In some embodiments, the support member has a sliding layer that abuts against the support body.

[0014] The vehicle according to an embodiment of the present invention includes the hood assembly of the vehicle described above.

[0015] According to an embodiment of the present invention, by applying the above-described hood assembly, the longitudinal crumple zone of the vehicle is increased, thereby increasing the crumple space.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The hood assembly 100 of a vehicle according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0033] like Figure 1 As shown, the vehicle hood assembly 100 according to an embodiment of the present invention includes: an engine hood 10 and a buffer bracket 20.

[0034] The engine hood 10 has a structural member below it. The buffer bracket 20 has a bracket body 21 and a bracket connection 22. The bracket connection 22 is connected to the engine hood 10. The bracket body 21 can cooperate with the structural member so that, in the event of a collision with the engine hood 10, the bracket body 21 can slide longitudinally along the surface of the structural member under the guidance of the structural member.

[0035] The bracket connecting part 22 serves to connect the buffer bracket 20 and the engine hood 10, thereby stabilizing the buffer bracket 20. The vehicle's longitudinal direction refers to the direction in which the front and rear of the vehicle are located, which can also be simply understood as... Figure 1 For ease of understanding, the longitudinal direction of the vehicle can be understood as the front-rear direction; however, this should not be considered a limitation of this application. When the hood 10 collides, the buffer bracket 20 moves, and the structural component is located on the movement path of the buffer bracket 20. The structural component is subjected to the impact force transmitted by the buffer bracket 20 and reacts the impact force onto the buffer bracket 20. For example, the structural component could be the vehicle front module 30, with its upper surface reacting the impact force onto the buffer bracket 20; or the structural component could be a protrusion on the vehicle front module 30, with its upper surface reacting the impact force onto the buffer bracket 20. Of course, these are merely examples and do not represent a limitation of this application.

[0036] During the collision of the engine hood 10, the engine hood 10 deforms and transmits the impact force to the buffer bracket 20. Under the action of the impact force and with the cooperation of the structural components, the bracket body 21 slides on the surface of the structural components.

[0037] It should be noted that the bracket body 21 is adapted to cooperate with the structural component, so that when the engine hood 10 is involved in a collision, the bracket body 21 can slide along the surface of the structural component in the longitudinal direction of the vehicle. Compared with the simple vertically collapsible solution of related technologies, this application designs a new type of collapse, in which the engine hood 10 can collapse in the longitudinal direction of the vehicle, thereby expanding the new collapse space. Based on the existing technology, the collapse space is increased, the injury value during the head collision is reduced, and the overall vehicle safety is improved.

[0038] According to an embodiment of the present invention, the hood assembly 100 of a vehicle slides longitudinally in the vehicle when the hood 10 is involved in a collision by providing a bracket body 21. Compared with the vertical crumple direction in related technologies, this increases the crumple space in the longitudinal direction of the vehicle, thereby increasing the crumple space and reducing the injury value during a head collision. It is also adapted to a new type of hood 10.

[0039] In some embodiments, the support body 21 includes a first support 211 and a second support 212.

[0040] The first bracket 211 is connected at one end to the bracket connecting part 22, and the other end abuts against the structural member and can slide longitudinally along the surface of the structural member under the guidance of the structural member. That is, the first bracket 211 is subjected to impact force and slides on the surface of the structural member with the cooperation of the structural member. The first bracket 211 provides crumple zone in the longitudinal direction of the vehicle, improving safety.

[0041] The second bracket 212 is connected at one end to the bracket connecting part 22 and at the other end to the first bracket 211, and can move under the drive of the first bracket 211. By setting the second bracket 212 to move under the drive of the first bracket 211, the second bracket 212 further absorbs the impact force on the basis of the first bracket 211, thereby improving safety.

[0042] It is understandable that when the engine hood 10 is involved in a collision, the first support 211 is a weak point because of its sliding design relative to the structural components. The first support 211 slides first, causing the engine hood 10 to collapse longitudinally in the vehicle. When the first support 211 slides to its limit position, it can no longer slide. At this point, the second support 212 becomes a weak point, and it deforms to absorb the impact force, thus improving safety.

[0043] like Figure 1 , Figure 2 As shown, in some embodiments, the support body 21 includes a first support 211, a second support 212 and a third support 213.

[0044] Both the first bracket 211 and the second bracket 212 are connected to the bracket connecting part 22.

[0045] The third bracket 213 abuts against the structural component, and its two ends are respectively connected to the ends of the first bracket 211 and the second bracket 212 away from the bracket connection portion 22. The third bracket 213 can slide longitudinally along the surface of the structural component under the guidance of the structural component. By setting the third bracket 213, the bracket body 21 slides better on the surface of the structural component, improving reliability and thus making the buffering effect of the buffer bracket 20 more stable.

[0046] It is understandable that when the engine hood 10 is involved in a collision, the sliding design of the third bracket 213 relative to the structural components makes the buffer bracket 20 a weak point in the longitudinal direction of the vehicle. The third bracket 213 slides first, causing the engine hood 10 to collapse in the longitudinal direction of the vehicle. When the third bracket 213 slides to its limit and can no longer slide, the buffer bracket 20 becomes a weak point in the vertical direction. The second bracket 212 deforms to absorb the impact force and improve safety.

[0047] like Figure 1 As shown, in some embodiments, the third bracket 213 is in surface contact with the surface of the structural component. By setting the third bracket 213 to be in surface contact with the surface of the structural component, the sliding of the third bracket 213 on the structural component is more stable, while providing a certain supporting function, improving the supporting capacity of the buffer bracket 20 when the engine hood 10 does not collide, improving the dent resistance of the engine hood 10, and improving NVH performance.

[0048] like Figure 1 As shown, in some embodiments, the first support 211 has a set angle with the surface of the structural member, the set angle being A, where A is less than 90 degrees. By setting the set angle between the first support 211 and the surface of the structural member to be less than 90 degrees, the first support 211 can slide smoothly relative to the surface of the structural member, making the function of the buffer support 20 more stable.

[0049] It should be noted that the set angle between the first support 211 and the surface of the structural component is less than 90 degrees. When the impact force on the first support 211 is transmitted to the surface of the structural component, the set angle between the first support 211 and the surface of the structural component causes the impact force to be decomposed, allowing the support body 21 to slide smoothly on the surface of the structural component.

[0050] For example, the angle can be set to 80 degrees; or 70 degrees; or 60 degrees; or 50 degrees; or 40 degrees; or 30 degrees; or 20 degrees; or 10 degrees. Of course, the angle can also be other values ​​less than 90 degrees, which will not be elaborated here.

[0051] In some embodiments, the angle is set to 50 degrees. By setting the angle to 50 degrees, the stress-bearing capacity of the support body 21 is improved in accordance with safety regulations.

[0052] like Figure 1 As shown, in some embodiments, the surface of the structural component is parallel to a horizontal plane. By setting the surface of the structural component to be parallel to a horizontal plane, the structural component can better decompose impact forces, further improving the crumple zone effect.

[0053] like Figure 2 As shown, in some embodiments, the second support 212 has an inducing portion 2121 to induce the second support 212 to bend along the inducing portion 2121. By providing the inducing portion 2121 to induce the second support 212 to bend, the difficulty of bending the second support 212 is reduced, thereby better absorbing impact force and improving the crumple zone effect.

[0054] Specifically, the guide part 2121 is a bending angle on the second bracket 212. When the second bracket 212 is under force, the bending angle makes the second bracket 212 more likely to bend, reducing the head injury when the engine hood 10 collides with the head, while improving the ease of installation.

[0055] like Figure 2 As shown, in some embodiments, the second bracket 212 is provided with a weakening hole 2122, which extends along the length of the second bracket 212. By providing the weakening hole 2122, the strength of the second bracket 212 is further weakened, making the second bracket 212 easier to collapse, further reducing the injury to the head when the engine hood 10 collides with the head, while also improving installation convenience. The fact that the weakening hole 2122 extends along the length of the second bracket 212 enhances its weakening effect.

[0056] In some specific embodiments, the buffer support 20 is made of DC04 steel.

[0057] In some specific embodiments, the bracket connection 22 is welded to the engine hood 10.

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the structural component includes a bracket support 11 mounted on the vehicle front-end module 30. By separately configuring the support support to cooperate with the bracket body 21, it facilitates future replacement and maintenance.

[0059] like Figure 3 As shown, in some embodiments, the support member 11 has a sliding layer 111 that abuts against the support body 21.

[0060] In some specific embodiments, the sliding layer 111 is constructed in an arc shape to reduce the contact area with the support body 21, which is beneficial to the slippage of the support body 21.

[0061] In some specific embodiments, the sliding layer 111 is made of ABS plastic (a terpolymer of acrylonitrile, butadiene, and styrene). By making the sliding layer 111 of ABS, the friction between the support body 21 and the sliding layer is reduced, thereby improving the sliding effect.

[0062] It should be noted that ABS plastic is relatively smooth, making the movement trajectory of the buffer bracket 20 easier to control, thus changing the problem that rubber material buffer devices in related technologies are not easy to slip off.

[0063] In some embodiments, the bracket support 11 is threadedly connected to the vehicle front-end module 30 to adjust the distance between the bracket support 11 and the hood 10. By setting the bracket support 11 to be threadedly connected to the vehicle front-end module 30, the height of the frame support 11 can be adjusted to accommodate different sizes of space between the hood 10 and the vehicle front-end module 30.

[0064] In some embodiments, the support member 11 is configured as an elastic member to reduce noise.

[0065] In some specific embodiments, the engine hood 10 corresponds to two buffer brackets 20, as shown in the reference. Figure 4 As shown (the dashed box labeled 12 in the figure represents the connection between the bracket connection 22 and the engine hood 10), two buffer brackets 20 are spaced apart in the lateral direction of the vehicle to improve the support capacity for the engine hood 10.

[0066] It should be noted that the lateral direction of a vehicle refers to its width, which can also be simply understood as... Figure 4 Left and right directions.

[0067] Specifically, there are two support members 11, as shown in the reference. Figure 5 As shown (the dashed box labeled 31 in the figure represents the connection between the vehicle front module 30 and the bracket support 11), the bracket support 11 and the corresponding buffer bracket 20 are mounted on the vehicle front module 30.

[0068] This invention utilizes the cooperation between the buffer bracket 20 and the bracket support member 11 to achieve two stages of deformation in a head impact test. In the first deformation stage, the buffer bracket 20 is weak in the longitudinal direction of the vehicle. The first bracket 211 transmits the impact force to the third bracket 213. The third bracket 213 contacts the sliding layer 111 on the bracket support member 11 at a set angle of 50 degrees. The sliding layer 111 is parallel to the horizontal plane. Guided by the sliding layer 111 on the bracket support member 11, the third bracket 213 slides backward, absorbing the impact force. In the second deformation stage, the third bracket 213 and the first bracket 211 slide to their limit and cannot move further. The buffer bracket 20 becomes weak in the vertical direction of the vehicle, and the second bracket 212 deforms, absorbing the impact force.

[0069] Compared to related technologies where the buffer device directly deforms in the vertical direction to absorb impact force, this application increases the longitudinal crumple zone of the vehicle. Furthermore, in the second deformation stage, only the second bracket 212 deforms. Under the same impact force, a single bracket deforms, thereby increasing the crumple zone. The overall effective crumple space can reach 75mm. Moreover, when no collision occurs, the surface contact between the third bracket 213 and the sliding layer 111 improves the stability of the buffer bracket 20 and enhances the NVH performance of the engine hood 10. Both the buffer bracket 20 and the bracket support member 11 can undergo elastic deformation, effectively adjusting gap differences and reducing the impact of manufacturing errors in vehicle components.

[0070] The vehicle according to an embodiment of the present invention includes the hood assembly 100 of the vehicle described above.

[0071] According to an embodiment of the present invention, by applying the above-described hood assembly 100, the crumple zone in the longitudinal direction of the vehicle is increased, thereby increasing the crumple space.

[0072] Other configurations and operations of the vehicle hood assembly 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
