[0002] In the event of a collision between a vehicle and a pedestrian, pedestrians are highly susceptible to injury. Therefore, improving vehicle safety technology and reducing the injury rate in road traffic accidents is of paramount importance. As a crucial area for pedestrian head protection testing, the design of the fender's mounting bracket is critical in reducing the Head Injury Criterion (HIC). Summary of the Invention

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

[0005] An embodiment of this application provides a mounting bracket, comprising:

[0006] The frame has a collapsible space, and one side of the frame along the first direction is used to connect with the impacted component;

[0007] An elastic element is disposed within the collapsible space, the volume of which is reduced to cause the elastic element to deform along a first direction.

[0008] In some embodiments, fasteners are threaded to the frame to connect the impact member to one side of the frame along a first direction, and the elastic element is a helical compression spring whose axial direction is along the first direction.

[0009] In some embodiments, the frame includes a mounting portion, a crushing plate, and a connecting seat. The mounting portion and the connecting seat are disposed at both ends of the crushing plate along a first direction to jointly define the crumple space. The mounting portion is used to connect with the impacted component, and the thickness direction of the crushing plate is perpendicular to the first direction.

[0010] In some embodiments, the mounting portion includes a mounting plate and a fixing platform, the elastic element and the fixing platform are both located on the side of the mounting plate away from the impacted member along a first direction, one end of the elastic element is sleeved on the outer periphery of the fixing platform, and at least one of the mounting plate and the fixing platform is connected to the elastic element.

[0011] In some embodiments, a portion of the crumple plate protrudes in the thickness direction to form a crumple rib.

[0012] In some embodiments, there are multiple constriction ribs, and the multiple constriction ribs are arranged at intervals along a first direction.

[0013] In some embodiments, the crushing plate is formed with crushing holes extending through both sides of its thickness direction.

[0014] In some embodiments, the crumple plate is partially punched to form the crumple hole, and the punched sheet is bent toward one side of the thickness direction of the crumple plate to form a bent sheet. The bent sheet and the mounting portion are spaced apart along a first direction, and the elastic element is connected between the bent sheet and the mounting portion.

[0015] In some embodiments, the connector includes two connecting ears, which are respectively disposed on both sides of the pressure plate along the second direction, and the connecting ears and the mounting portion are both located on the same side in the thickness direction of the pressure plate.

[0018] Fender;

[0020] The mounting bracket provided in this application embodiment has two advantages. First, in the event of a collision between a vehicle and a pedestrian, the pedestrian's head may impact a striking component, such as a fender. The impact force on the fender is transmitted to the mounting bracket. The impact force on the bracket reduces the volume of the crumple zone, causing the elastic element to deform along a first direction. This deformation of the elastic element absorbs the impact energy between the pedestrian and the vehicle, thereby reducing the injury to the pedestrian and lowering the head injury index. Second, during the assembly of the fender and the bracket, and during vehicle use, the elastic element provides support to the bracket, reducing its deformation. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. In the description of the embodiments of the present application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] Please see Figure 1 This application provides a mounting bracket, which includes a frame 1 and an elastic element 2. The frame 1 forms a collapsible space 1a, and one side of the frame 1 along a first direction is used to connect with a member subjected to impact. The elastic element 2 is disposed within the collapsible space 1a, and the volume of the collapsible space 1a is reduced to cause the elastic element 2 to deform along the first direction.

[0030] Mounting brackets are used in vehicles. These brackets can be used in all vehicle applications where pedestrian head protection testing areas are located, where pedestrian head space in the first direction is insufficient, and where there are no high rigidity or modal requirements during vehicle use.

[0031] A collision-bearing component refers to a part of a vehicle that is struck by an external object, such as a pedestrian's head. Collision-bearing components include, but are not limited to, fenders. That is, the mounting bracket can mount the fender to the vehicle body 100. For ease of description, this application will be described below using the fender as the collision-bearing component.

[0032] Please see Figure 1 and Figure 3 This application also provides a vehicle, which includes a vehicle body 100, a fender, and a mounting bracket as described in any embodiment of this application. The bracket 1 is connected to the fender on one side along a first direction, and the bracket 1 is connected to the vehicle body 100 on the other side along the first direction.

[0033] Fenders are structures used to protect pedestrians and provide pedestrian protection functions.

[0034] For example, the frame 1 may be located in the side beam area of ​​the engine compartment of the vehicle body 100.

[0035] It should be noted that the vehicles in the embodiments of this application include, but are not limited to, gasoline-powered vehicles, electric vehicles, or hybrid electric vehicles, etc.

[0036] The mounting bracket provided in this application embodiment has two advantages. First, in the event of a collision between a vehicle and a pedestrian, the pedestrian's head may impact a striking component, such as a fender. The impact force on the fender is transmitted to the mounting bracket. The impact force on the bracket body 1 reduces the volume of the crumple zone 1a. This reduction in the volume of the crumple zone 1a causes the elastic element 2 to deform along a first direction. This deformation of the elastic element 2 absorbs the impact energy between the pedestrian and the vehicle, thereby reducing the injury to the pedestrian and lowering the head injury index. Second, during the assembly of the fender and the bracket body 1, and during vehicle use, the elastic element 2 provides support to the bracket body 1, reducing the deformation of the bracket body 1.

[0037] The vehicle provided in this application embodiment not only improves the rigidity of the frame 1 to resist deformation during the assembly of the fender and frame 1 and during vehicle use, ensuring the appearance gap of the vehicle, but also absorbs the impact energy between the pedestrian and the vehicle through the deformation of the elastic element 2 in the event of a collision between the vehicle and a pedestrian, thereby reducing the injury to the pedestrian.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 The fastener is threaded to the frame 1 to connect the impacted part to one side of the frame 1 along the first direction. The elastic element 2 is a helical compression spring with the axis of the helical compression spring along the first direction.

[0039] For example, the axis of the fastener is aligned with the axis of the helical compression spring. The axis of the fastener refers to the direction of the axis around which the fastener rotates.

[0040] Because the frame 1 is threaded with fasteners, the fasteners need to be tightened during the assembly of the fender to the frame 1. In related technologies, if the requirement for sufficient crush deformation of the frame 1 during a collision is prioritized, the frame 1 will be weak in resisting deformation when the fasteners are tightened during fender assembly, making it prone to torsional deformation and compromising appearance accuracy. If the requirement for assembly strength of the frame 1 is prioritized, the crush deformation of the frame 1 during a collision may be insufficient, increasing the risk of injury to pedestrians, such as to the head.

[0041] In this application, on the one hand, the impact force from the impacted component, such as the fender, is along a first direction, and the axial direction of the helical compression spring is also along the first direction. That is, the helical compression spring deforms significantly when subjected to an impact force along the first direction. Thus, the helical compression spring is prone to axial compression deformation when subjected to an impact force along the first direction, which does not hinder the collapse space 1a from collapsing along the first direction. The helical compression spring can also convert the collision impact energy into potential energy, further reducing damage. On the other hand, during the assembly of the fender and the frame 1, the torque generated by the rotating fasteners acts on the frame 1 and is transmitted to the helical compression spring. The helical compression spring can withstand a large torque, meaning that the helical compression spring deforms little or not at all when subjected to torque. Therefore, the helical compression spring can provide sufficient force to resist the torque during the assembly of the fender and the frame 1, providing anti-torsional force to ensure that the frame 1 does not deform and improve the appearance accuracy of the vehicle. In other words, by utilizing the characteristics of helical compression springs that are not easily deformed when subjected to helical force and are easily compressed axially, the problem of not being able to simultaneously ensure sufficient crushing of the mounting bracket and easy torsion deformation during assembly can be solved. This ensures that the mounting bracket is not easily deformed during assembly while also ensuring sufficient crushing during collision, thereby reducing the head injury value of pedestrians.

[0042] In some embodiments, the tightening direction of the fastener is opposite to the helical compression spring's direction of rotation. For example, if the fastener is tightened to the left, the helical compression spring will rotate to the right. Or, for another example, if the fastener is tightened to the right, the helical compression spring will rotate to the left. This ensures that the helical compression spring provides sufficient elastic force to resist the torque during the assembly of the fender and frame 1.

[0043] For example, helical compression springs include, but are not limited to, cylindrical helical compression springs.

[0044] For example, the coil compression spring can achieve a balance between the axial pressure and the helical torque by adjusting the coil diameter, so as to better resist the torsion during the fender assembly process and fully collapse and deform during the collision.

[0045] For example, one of the fasteners and the frame 1 is formed with an external thread, and the other of the fasteners and the frame 1 is formed with an internal thread adapted to the external thread.

[0046] Taking fasteners with external threads as an example, fasteners include, but are not limited to, screws or bolts.

[0047] In one embodiment, the frame 1 is made of metal.

[0048] In one embodiment, the frame 1 is a sheet metal structure. A sheet metal structure refers to a structure formed by cold working processes such as stamping, shearing, and / or bending of metal sheets. Thus, the frame 1 has low manufacturing costs and is easy to form.

[0049] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The frame 1 includes a mounting part 11, a crumple plate 12, and a connecting seat 13. The mounting part 11 and the connecting seat 13 are disposed at both ends of the crumple plate 12 along a first direction to jointly define a crumple space 1a. The mounting part 11 is used to connect with the impacted component, and the thickness direction of the crumple plate 12 is perpendicular to the first direction. That is, the mounting part 11, the connecting seat 13, and the crumple plate 12 jointly define the crumple space 1a. Specifically, the connecting seat 13 is used to connect with the vehicle body 100. The crumple plate 12 has a plate-like structure and is capable of crumple deformation, that is, when the crumple plate 12 is broken, it produces crumple-type energy absorption. The impact force acts on the mounting part 11 and is transmitted to the crumple plate 12. Under the action of the impact force, the crumple plate 12 undergoes crumple-type energy absorption, i.e., permanent deformation, thereby reducing the volume of the crumple space 1a. Crumple deformation refers to the permanent deformation of the crumple plate 12 under the action of the impact force, converting kinetic energy into internal energy, thereby mitigating the impact on pedestrians.

[0050] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The mounting section 11 includes a mounting plate 111 and a fixing platform 112. Both the elastic member 2 and the fixing platform 112 are located on the side of the mounting plate 111 away from the fender along a first direction. One end of the elastic member 2 is sleeved on the outer periphery of the fixing platform 112. At least one of the mounting plate 111 and the fixing platform 112 is connected to the elastic member 2. Thus, the fixing platform 112 not only positions the elastic member 2 but also reduces the risk of lateral bending of the elastic member 2. For example, one axial end of the helical compression spring can be sleeved on the outer periphery of the fixing platform 112.

[0051] For example, the fixing platform 112 can be fixed to the mounting plate 111 by welding, or the fixing platform 112 can be integrally formed with the mounting plate 111.

[0052] For example, the fastener is threadedly connected to the mounting plate 112. In this way, during the tightening of the fastener, torque can be transmitted to the elastic element 2 through at least one of the mounting plate 111 and the mounting plate 112.

[0053] In one embodiment, the fastener has an external thread, and the mounting plate 112 has an internal thread adapted to the external thread. It is understood that the mounting plate 112 is located on the side of the mounting plate 111 away from the fender along a first direction, and the mounting plate 111 may have a through hole communicating with the internal thread of the mounting plate 112, through which the fastener passes and engages with the internal thread of the mounting plate 112.

[0054] In one embodiment, the elastic element 2 can be fixed to at least one of the mounting plate 111 and the fixing platform 112 by welding. That is, the elastic element 2 can be welded to the mounting plate 111. The elastic element 2 can also be welded to the fixing platform 112.

[0055] Welding methods include, but are not limited to, spot welding and / or CO2 welding, etc.

[0056] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 A portion of the crushing plate 12 protrudes towards its thickness to form a crumple rib 121. The crumple rib 121 acts as a crumple guide during impact, ensuring that the crushing plate 12 effectively crumples in a predetermined direction, such as the first direction, after being subjected to impact force. The stress-bearing capacity at the location of the crumple rib 121 is weaker than that of other parts of the crushing plate 12. When the crushing plate 12 is subjected to an impact force along the first direction, the location of the crumple rib 121 deforms first, further deforming towards its thickness, allowing the crushing plate 12 to rapidly crumple in the predetermined direction, i.e., the first direction.

[0057] In one embodiment, please refer to Figure 4 There are multiple contraction ribs 121, which are arranged at intervals along the first direction. Under the action of an impact force along the first direction, multiple positions of the contraction ribs 121 of the crushing plate 12 deform, ensuring that the crushing plate 12 is fully crushed and deformed during the collision.

[0058] In one embodiment, please refer to Figure 1 The projection plane of the contraction rib 121 is a plane perpendicular to the second direction. The projected shape of the contraction rib 121 is semi-circular, semi-elliptical, or polygonal, wherein the first direction, the second direction, and the thickness direction of the compression plate 12 are perpendicular to each other. Polygons include, but are not limited to, triangles, quadrilaterals, or pentagons. The semi-circular, semi-elliptical, or polygonal projected shape of the contraction rib 121 is easy to manufacture.

[0059] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The crumple plate 12 has crumple holes 12a extending through both sides of its thickness. Since the elastic element 2 provides anti-torsional force to the frame 1, the design of the crumple plate 12 can primarily focus on its full crumple during the collision, without needing to consider torsional deformation during fender assembly. Therefore, by reducing the structural strength of the crumple plate 12 through the crumple holes 12a, the deformation capacity of the crumple plate 12 is further enhanced, ensuring that the crumple plate 12 can fully crumple and deform during the collision.

[0060] The shape of the collapse hole 12a is not limited; as an example, in one embodiment, please refer to [reference needed]. Figure 4The shape of the collapse hole 12a includes, but is not limited to, circles, ellipses, or polygons. Polygons include, but are not limited to, triangles, quadrilaterals, or pentagons.

[0061] As an example, in one embodiment, please refer to Figure 1 and Figure 4 The contraction hole 12a has contraction ribs 121 formed on both sides along the second direction. In this way, under impact force, both sides of the contraction hole 12a along the second direction can deform.

[0062] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The contraction ribs 121 on the two sides of the contraction hole 12a along the second direction are arranged in pairs evenly. That is, the two contraction ribs 121 distributed on both sides of the contraction hole 12a along the second direction are grouped together, and multiple groups of contraction ribs 121 are evenly distributed at intervals along the first direction.

[0063] It should be understood that the specific location, quantity, and size of the contraction ribs 121 can be optimized based on the collision simulation analysis results, so that they can fully contract and deform during the collision.

[0064] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The crushing plate 12 is partially punched to form a shrinkage hole 12a. The punched sheet is bent towards the thickness direction of the crushing plate 12 to form a bent piece 122. The bent piece 122 and the mounting part 11 are spaced apart along the first direction. The elastic member 2 is connected between the bent piece 122 and the mounting part 11. On the one hand, by punching out the shrinkage hole 12a and the bent piece 122 respectively, the purpose of manufacturing two structures in one step can be achieved, which not only saves materials but also reduces assembly steps. On the other hand, during the collision, the impact force is transmitted to the mounting part 11 and the crushing plate 12. The crushing plate 12 deforms and shortens in size along the first direction, causing the mounting part 11 to move closer to the bent piece 122. The shrinkage space 1a between the mounting part 11 and the bent piece 122 decreases, causing the elastic member 2 to undergo compressive deformation.

[0065] In one embodiment, the distance between the outer edge of the bent piece 122 and the elastic element 2, such as a helical compression spring, is between 1 mm and 2 mm. Thus, the bent piece 122 is of appropriate size and can stably support the elastic element 2, such as the helical compression spring.

[0066] In one embodiment, the bent piece 122 is formed with a positioning portion, and the end of the elastic member 2 away from the mounting portion 11 along the first direction is connected to the positioning portion.

[0067] For example, in one embodiment, the positioning part can be a through hole, and the end of the elastic member 2 away from the mounting part 11 along the first direction is formed with a hook. The hook passes through the through hole and hooks the surrounding part of the through hole. For example, the through hole can be formed on the bent piece 122 by stamping, which is simple and has low manufacturing cost.

[0068] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The connecting seat 13 includes two connecting ears 131, which are respectively disposed on both sides of the crushing plate 12 along the second direction. Both the connecting ears 131 and the mounting portion 11 are located on the same side of the thickness direction of the crushing plate 12. The connecting ears 131 are used to connect to the vehicle body 100. On the one hand, the connection between the frame 1 and the vehicle body 100 is made more stable by connecting to the vehicle body 1 through the two connecting ears 131. On the other hand, since both the connecting ears 131 and the mounting portion 11 are located on the same side of the thickness direction of the crushing plate 12, the mounting space occupied by the frame 1 inside the vehicle is smaller.

[0069] The connecting seat 13 can be non-detachably connected to the vehicle body 100, for example, by welding or stamping. The connecting seat 13 can also be detachably connected to the vehicle body 100, for example, by bolting.

[0070] In one embodiment, for example, the connecting ear 131 has a flange facing the vehicle body 100, and the surface of the flange facing the vehicle body 100 is welded to the vehicle body 100. Welding includes, but is not limited to, spot welding or CO2 welding, etc.

[0071] In one embodiment, the mounting plate 111, the crushing plate 12, and the connecting seat 13 are integrally formed sheet metal structures. The fixing component can be a nut, which is welded to the mounting plate 111.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
