[0035] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0036] Reference below Figures 1-8 A front anti-collision beam assembly 100 according to an embodiment of the present invention is described. The front anti-collision beam assembly 100 can improve the installation strength of the front bumper, so that the front bumper can be stably supported and installed on the front anti-collision beam 1, thereby improving the energy absorption effect, thereby ensuring that the vehicle has high pedestrian protection performance and improving vehicle quality. In addition, the front bumper is easy to install, low in cost, and highly reliable.

[0037] like Figures 1-8 As shown, the front anti-collision beam assembly 100 according to an embodiment of the present invention includes: a front anti-collision beam 1 and a front bumper mounting assembly 2.

[0038] The front anti-collision beam 1 has high strength and rigidity, which can improve the strength of the vehicle. When the vehicle collides, it absorbs and disperses the collision energy and reduces the deformation of the vehicle body. The rear side of the front anti-collision beam 1 is connected to the energy absorption box 3, that is, the front anti-collision beam 1 can disperse the energy to the energy absorption box 3 on the rear side during a collision, so as to absorb a certain amount of impact energy through the deformation of the energy absorption box 3, reduce the degree of damage to the vehicle, and thus reduce the injury to the passengers.

[0039] The front bumper mounting assembly 2 is used to connect the front anti-collision beam 1 with the front bumper and to install the energy absorption box 3 on the front anti-collision beam 1, wherein there are at least two front bumper mounting assemblies 2, that is, the number of front bumper mounting assemblies 2 can be set to at least two, three or even more. Setting up multiple front bumper mounting assemblies 2 can improve the energy absorption effect of the front anti-collision beam assembly 100 and easily improve the installation stability of the front bumper. In actual design, two front bumper mounting assemblies 2 can be set, and the two front bumper mounting assemblies 2 can be symmetrically installed at both ends of the front anti-collision beam 1.

[0040] At least two front bumper mounting assemblies 2 are distributed on the front anti-collision beam 1 at intervals along the lateral direction of the vehicle. The front bumper mounting assembly 2 includes a main bracket 21 and two side brackets 22. The two side brackets 22 are installed on the lateral sides of the main bracket 21 at intervals. At least part of the main bracket 21 is located on the front side of the front anti-collision beam 1 to be connected to the front bumper, and the rear part of the main bracket 21 is connected to the energy absorption box 3. The side brackets 22 are connected to the upper part of the front anti-collision beam 1 and are used to be connected to the front bumper.

[0041] Specifically, the front anti-collision beam 1 is mounted on the front side of the vehicle and extends laterally along the front side of the vehicle. The main bracket 21 of the front bumper mounting assembly 2 is used to connect the energy absorption box 3 and the front bumper. The main bracket 21 extends forward a certain distance, that is, a portion of the main bracket 21 is located on the front side of the front anti-collision beam 1 and is separated from the front anti-collision beam 1 by a certain distance, and is used to connect the front bumper. The rear portion of the main bracket 21 extends backward along the upper and lower surfaces of the front anti-collision beam 1 for a distance, and is used to connect the energy absorption box 3. Since the main bracket 21 is separated from the front side of the front anti-collision beam 1 by a certain distance, when the front bumper collides, the main bracket 21 is easy to deform and absorb energy, thereby reducing the impact force on pedestrians, thereby protecting pedestrians. In actual design, the main bracket 21 and the side bracket 22 can be connected to the front anti-collision beam 1 and the energy absorption box 3 by bolt connection, welding, etc.

[0042] Two side brackets 22 are installed on both sides of the main bracket 21 along the length of the front anti-collision beam 1, and both side brackets 22 are installed on the upper surface of the front anti-collision beam 1. The upper part of the side bracket 22 is used to connect the front bumper. In this way, the main bracket 21 is set in the middle position of the two side brackets 22, which can work together with the side brackets 22 on both sides to improve the installation strength of the front bumper. Therefore, when the two front bumper mounting assemblies 2 are installed, the four side brackets 22 can be spaced apart and distributed on the upper surface of the front anti-collision beam 1. The two main brackets 21 are respectively located between the corresponding side brackets 22, so that the front bumper mounting assemblies 2 are dispersed on the front anti-collision beam 1, so that each area of ​​the front anti-collision beam 1 has a front bumper installation support point, thereby ensuring that each area has high performance, so that the front bumper is stably supported and installed on the front anti-collision beam 1, and the connection strength between the front bumper and the front anti-collision beam 1 is improved. Among them, the side bracket 22 can also deform to absorb collision energy, and work together with the main bracket 21 and the energy absorption box 3 to further improve the energy absorption effect, which is beneficial to protecting pedestrians.

[0043] Therefore, the front bumper can be connected vertically through the side bracket 22 and connected longitudinally through the main bracket 21, so that the front bumper can be stabilized in the lateral position, multiple installation support points can be provided for the front bumper, and the installation strength and stability of the front bumper on the front anti-collision beam 1 can be improved. In addition, the side bracket 22 and the main bracket 21 can both deform to absorb energy, and work together with the energy absorption box 3 to improve the energy absorption effect and avoid serious injuries to pedestrians.

[0044] According to the front bumper beam assembly 100 of the embodiment of the present invention, by providing at least two front bumper mounting assemblies 2 including a main bracket 21 and two side brackets 22, the front bumper and the energy absorption box 3 are connected to the front bumper mounting assembly 2, so that the installation strength of the front bumper can be improved, and the front bumper can be stably supported and installed on the front bumper beam 1, thereby improving the energy absorption effect, thereby ensuring that the vehicle has high pedestrian protection performance and improving vehicle quality. In addition, the front bumper is easy to install, low in cost, and highly reliable.

[0045] In some embodiments, the main bracket 21 includes a top plate portion 211, a middle plate portion 212 and a bottom plate portion 213 connected in sequence, the middle plate portion 212 is located on the front side of the front anti-collision beam 1, and the middle plate portion 212 is used to be connected to the front bumper. The top plate portion 211 and the bottom plate portion 213 are respectively located on the upper and lower sides of the front anti-collision beam 1 for connecting to the energy absorption box 3.

[0046] Specifically, if Figure 1 、 Figure 5 and Figure 6As shown, the top plate portion 211, the middle plate portion 212 and the bottom plate portion 213 are sequentially connected to form a main bracket 21 open to the rear, the middle plate portion 212 is located at the front side of the front anti-collision beam 1, and the front bumper is connected to the front side of the middle plate portion 212, which can be connected to the front bumper by bolt connection, so that the front bumper is easy to install and disassemble, as shown in the following figure. Figure 6 As shown, three bolts are provided on the middle plate portion 212, which can ensure that the front bumper has sufficient installation strength. Of course, the installation number and position of the bolts can also be selected according to actual needs and space size, and are not limited to those described in this embodiment.

[0047] The upper and lower ends of the middle plate portion 212 extend rearward a certain distance to form a top plate portion 211 and a bottom plate portion 213, and the top plate portion 211 is located on the upper side of the front anti-collision beam 1, and is connected to the upper side of the energy absorption box 3 on the rear side of the anti-collision beam. The bottom plate portion 213 is located on the lower side of the front anti-collision beam 1, and is connected to the lower side of the energy absorption box 3. The top plate portion 211 and the bottom plate portion 213 can be connected to the energy absorption box 3 by bolts to facilitate installation and disassembly.

[0048] In some embodiments, the top plate portion 211 and / or the bottom plate portion 213 are detachably connected to mounting legs 214 , and the mounting legs 214 extend to the rear side of the front anti-collision beam 1 to be connected to the energy absorption box 3 .

[0049] That is, the main support 21 can be connected to the energy absorption box 3 by installing the legs 214, and the top plate 211 and / or the bottom plate 213 can be detachably connected to the installation legs 214, which is convenient for installing and removing the main support 21 and the energy absorption box 3. Figure 7 and Figure 8 As shown, the interior of the energy absorption box 3 is hollow, the rear side is open, the front side wall is bolted to the front anti-collision beam 1, the mounting legs 214 are constructed in an L-shape, and there are two mounting legs 214 in total. The two side walls of the upper and lower mounting legs 214 are fit-connected to the left and right side walls of the energy absorption box 3, which can be connected by welding to ensure the installation strength and reliability of the energy absorption box 3, wherein the upper side surface of the upper mounting leg 214 is fit-connected to the top plate portion 211 by bolts, and the lower side surface of the lower mounting leg 214 is also provided with a downward flange, and the bottom plate portion 213 is also provided with a downward flange accordingly. The two flanges can be connected by providing bolt through holes on the flange, so that the lower mounting leg 214 is connected to the bottom plate portion 213.

[0050] Therefore, by connecting the main bracket 21 with the energy absorption box 3 through the installation legs 214, the energy absorption box 3 can be stably installed on the rear side of the front anti-collision beam 1 while ensuring the installation strength of the main bracket 21, thereby ensuring the energy absorption effect.

[0051] In some embodiments, the middle plate portion 212 is provided with an avoidance hole 2121 , and the avoidance hole 2121 is located in front of the energy absorption box 3 .

[0052] Specifically, the avoidance hole 2121 is provided to leave installation space for the energy absorption box 3. The front side wall of the energy absorption box 3 is connected to the front anti-collision beam 1 with bolts. The avoidance hole 2121 facilitates the installation and removal of the bolts, thereby facilitating the installation and removal of the energy absorption box 3. Figure 6 As shown, the middle plate portion 212 is provided with an avoidance hole 2121 , which is constructed as a square hole. The avoidance hole 2121 exposes the mounting bolts of the energy absorption box 3 , and the mounting bolts of the front bumper are located around the avoidance hole 2121 .

[0053] In some embodiments, the lateral width of the top plate portion 211 and the lateral width of the bottom plate portion 213 are both smaller than the lateral width of the middle plate portion 212. By designing the lateral width of the middle plate portion 212 to be larger, the surface area of ​​the middle plate portion 212 can be increased, thereby increasing the connection points between the middle plate portion 212 and the front bumper, so that the middle plate portion 212 and the front bumper are stably connected, thereby increasing the connection strength between the two.

[0054] Among them, the width of the top plate portion 211 along the transverse direction, the width of the bottom plate portion 213 along the transverse direction, and the width of the middle plate portion 212 along the transverse direction can all be adjusted, thereby adjusting the energy absorption effect of the main bracket 21 to match different needs.

[0055] like Figure 6 As shown, the middle plate portion 212 can be constructed as a square plate, the width of which is greater than the width of the top plate portion 211 and the bottom plate portion 213. In actual design, the width of the top plate portion 211 along the transverse direction, the width of the bottom plate portion 213 along the transverse direction and the width of the middle plate portion 212 along the transverse direction can be designed to be within the range of 50mm-100mm, and the specific values ​​can be flexibly adjusted according to actual needs.

[0056] In some embodiments, the main bracket 21 also includes a crush portion 215 connected between the top plate portion 211 and the middle plate portion 212. The crush portion 215 is constructed to bend upward and protrude above the front side of the front bumper beam 1 so that the middle plate portion 212 is separated from the front bumper beam 1 in the front-to-back direction and defines a crush space.

[0057] The crushing portion 215 is provided to separate a distance between the front side of the front anti-collision beam 1 and the middle plate portion 212, forming a crushing space. Therefore, when the vehicle collides, it is beneficial for the main bracket 21 to deform in the crushing space to absorb energy and improve pedestrian protection performance.

[0058] Specifically, if Figure 5 and Figure 6As shown, the rear part of the top plate portion 211 is connected to the mounting leg 214, and the front part of the top plate portion 211 is bent and protruded upward to form a crushed portion 215. The height distance between the upper side surface of the crushed portion 215 and the upper side surface of the front anti-collision beam 1 is H, and the space distance between the middle plate portion 212 and the front side of the front anti-collision beam 1 is M. It can be understood that the larger H is, the larger the height distance between the upper side surface of the crushed portion 215 and the upper side surface of the front anti-collision beam 1 is, and the more conducive it is for the upper part of the main bracket 21 to deform and absorb energy, thereby improving the pedestrian protection performance. Similarly, the larger M is, the larger the crushed space between the middle plate portion 212 and the front anti-collision beam 1 is, and the more conducive it is for the main bracket 21 to deform and absorb energy, thereby improving the pedestrian protection performance. Among them, the range of M is not less than 73mm, so as to achieve the energy absorption effect.

[0059] like Figure 6 As shown, the bottom plate portion 213 tilts downward and forms an angle greater than 90° with the middle plate portion 212, and the angle is b. The larger b is, that is, the larger the angle between the bottom plate portion 213 tilts downward and the middle plate portion 212 is, the more conducive it is for the lower part of the main bracket 21 to deform and absorb energy, thereby improving pedestrian protection performance.

[0060] Therefore, when the vehicle collides, after absorbing energy through the middle plate portion 212, it can continue to absorb energy through the upper crushed portion 215, forming a two-stage energy absorption structure, which deforms and absorbs energy respectively to improve the energy absorption effect, and then dissipates the absorbed energy, thereby protecting pedestrians and preventing them from being seriously injured.

[0061] In actual design, the values ​​of H, b, and M can be flexibly adjusted according to actual needs and space size to achieve the actual optimal energy absorption effect, and are not limited to those described in this embodiment.

[0062] In some embodiments, the side bracket 22 includes a first plate portion 221, a second plate portion 222 and a third plate portion 223. The first plate portion 221 and the third plate portion 223 are respectively connected to the upper and lower ends of the second plate portion 222 and are bent toward different sides relative to the second plate portion 222, that is, the side bracket 22 can form a Z-shaped structure, which is conducive to its deformation and thus energy absorption.

[0063] Among them, the third plate portion 223 is connected to the front anti-collision beam 1, and the first plate portion 221 is used to be connected to the front bumper, and the third plate portion 223 can be connected to the front anti-collision beam 1 by bolt connection, welding and other connection methods, and the first plate portion 221 can be connected by bolt connection, clamping, welding and other methods.

[0064] Specifically, if Figure 5 and Figure 6As shown, the side bracket 22 is installed on the upper side of the front anti-collision beam 1. In the side bracket 22, the first plate portion 221 is bent forward from the upper end of the second plate portion 222, and the third plate portion 223 is bent backward from the lower end of the second plate portion 222. The third plate portion 223 is connected to the upper side of the front anti-collision beam 1 by bolts, so as to facilitate the installation and disassembly of the side bracket 22, which is flexible and convenient, and improves the connection reliability between the two. Among them, the angle formed between the third plate portion 223 and the second plate portion 222 is a. The size of a, that is, the size of the angle formed between the third plate portion 223 and the second plate portion 222, determines the energy absorption capacity of the side bracket 22. a can be greater than 90° or less than or equal to 90°. It can be understood that the smaller a is, that is, the smaller the angle formed between the third plate portion 223 and the second plate portion 222, the closer the third plate portion 223 is to the second plate portion 222. The larger a is, that is, the larger the angle formed between the third plate portion 223 and the second plate portion 222, the further away the third plate portion 223 is from the second plate portion 222, so that the second plate portion 222 can deform more and approach the third plate portion 223, reducing the angle between the two and absorbing more energy. Therefore, when the energy absorption demand is low, a can be set to less than 90°, and when the energy absorption demand is high, a can be set to greater than 90°. In actual design, the specific value of a can be designed according to actual needs.

[0065] In some embodiments, the third plate portion 223 is provided with a snap-fit ​​portion 2231 , and the snap-fit ​​portion 2231 is used for snap-fitting and connecting with the front bumper, and / or the second plate portion 222 is provided with a weakened hole 2221 .

[0066] like Figure 6 and Figure 7 As shown, the upper surface of the third plate portion 223 is provided with a snap-fit ​​portion 2231. The snap-fit ​​portion 2231 can be configured as a latch that can be pressed against the front bumper to achieve a snap-fit ​​connection between the side bracket 22 and the front bumper, making installation and removal flexible and convenient while reducing the number of bolts required. Furthermore, the surface of the second plate portion 222 is provided with two laterally distributed weakening holes 2221. The provision of the weakening holes 2221 ensures the strength of the side bracket 22 while facilitating its deformation and energy absorption, thereby enhancing the energy absorption effect and, in turn, improving the vehicle's pedestrian protection performance. While maintaining a certain strength for the side bracket 22, the size and position of the weakening holes 2221 can be flexibly adjusted. The larger the weakening holes 2221, the greater the deformation capacity of the side bracket 22, and the more energy it absorbs.

[0067] In some embodiments, there are two front bumper mounting assemblies 2 and they are symmetrically distributed relative to the center of the front anti-collision beam 1 .

[0068] Specifically, if Figure 1-Figure 5As shown, two sets of front bumper mounting assemblies 2 are installed on the front bumper beam 1, and are symmetrically distributed on both sides along the center of the front bumper beam 1, so that there are four side brackets 22 and two main brackets 21 distributed on the front bumper beam 1, of which the two side brackets 22 are symmetrically distributed at the left and right ends, and the two side brackets 22 are distributed close to the center. As a result, the front bumper support mounting points are distributed in various areas of the front bumper beam 1, which can improve the installation stability and reliability of the front bumper, and the main brackets 21 and the side brackets 22 can be deformed to absorb energy, which can ensure that each area of ​​the front bumper beam 1 has high performance.

[0069] Therefore, when the vehicle collides, the front bumper can drive the main bracket 21 and the side bracket 22 to move backward, and bend and deform to absorb energy, thereby protecting the safety of pedestrians.

[0070] Of the two side brackets 22 of each front bumper mounting assembly 2, the vertical height of the side bracket 22 farther from the center of the front anti-collision beam 1 is greater than the vertical height of the side bracket 22 closer to the center of the front anti-collision beam 1. Figure 1 and Figure 6 As shown, the two side brackets 22 symmetrically distributed at the left and right ends have a vertical height greater than the two side brackets 22 symmetrically distributed near the center of the front anti-collision beam 1. This is because the two side brackets 22 at both ends, while supporting and installing the front bumper, also need to perform deformation and energy absorption. Therefore, their vertical heights are set higher, which is conducive to their deformation and energy absorption, and the vertical height setting range can be between 90mm and 107mm. The two side brackets 22 symmetrically distributed near the center of the front anti-collision beam 1 mainly bear the role of supporting and installing the front bumper, and the deformation and energy absorption role is relatively small. Therefore, their vertical heights are set lower, and the vertical height setting range can be between 50mm and 72mm.
