[0002] Many new energy vehicles have front through-lights or front through-light dummy lights (collectively referred to as front through-light assemblies in this application), but since the front through-light assemblies are cavity structures, their own structure is relatively rigid, and the front bumper also needs a certain degree of support rigidity to prevent driving vibration. Especially for vehicles with relatively low front faces, the front through-light assemblies will directly impact pedestrians' thighs in the event of a collision, causing serious damage to pedestrians' legs, etc.

[0003] Due to the high strength of the hood, in order to reduce the serious damage to the legs of pedestrians caused by the front end of the vehicle during a collision, in the relevant technology, a decorative panel with lower strength is set between the hood and the front through-light assembly. However, the decorative panel does not have the transparent effect of the lamp and will increase the installation gap, which will lead to a reduction in the sealing, reliability, aesthetics and sense of technology of the front end of the vehicle.

[0040] Many new energy vehicles have front through-lights and / or front through-light fake lights (collectively referred to as front through-light assemblies in this application) on their front faces. However, since the front through-light assemblies are cavity structures, their own structure is relatively hard and strong, and the front bumper also requires a certain degree of support rigidity to avoid driving vibrations. Especially for vehicles with relatively low front faces, the front through-light assemblies will directly impact pedestrians’ thighs in the event of a collision, causing serious damage to pedestrians’ legs, etc. Furthermore, due to the rigidity of the hood, that is, its high strength, in order to reduce the serious damage caused to pedestrians’ legs, etc. by the front end of the vehicle in the event of a collision, in the related art, a decorative panel with lower strength is provided between the hood and the front through-light assembly. However, the decorative panel does not have the transparent effect of the lamp and will increase the installation gap, which will reduce the sealing, reliability, aesthetics and sense of technology of the front end of the vehicle.

[0041] Based on the above considerations, the present application has made improvements to the front bumper bracket and front through-light assembly of the front bumper assembly, which can not only reduce the damage of the front through-light assembly to pedestrians and other impact objects, but also facilitate improving the sealing, technological sense and aesthetics of the front face of the vehicle.

[0042] First, the present application proposes a front bumper assembly, such as Figures 1 to 16 As shown, Figure 2 The embodiment does not show the right lamp and the right front bumper skin in the front lamp assembly 60. The front bumper assembly of this embodiment includes a front bumper bracket 20 and a front through-lamp assembly 30, wherein the front end surface (not marked in the figure) of the front bumper bracket 20 forms a mounting position A, and the front through-lamp assembly 30 is arranged at the mounting position A and is spaced from the front end surface (not marked in the figure) of the front bumper bracket 20 to form a collapse space B of the front through-lamp assembly 30; wherein the upper end surface of the front through-lamp assembly 30 is configured to connect to the hood 40 of the vehicle.

[0043] The front through-light assembly 30 may include a front through-light and / or a front through-light dummy lamp. The upper end surface of the front through-light assembly 30 refers to the side surface of the front through-light assembly 30 facing upward of the vehicle when the vehicle is in use.

[0044] Among them, the front end face of the front bumper bracket 20 refers to the side of the front bumper bracket 20 facing the front of the vehicle when the vehicle is in use, and the front end face of the front bumper bracket 20 can be used to install the front bumper 50; a crumple space B is formed between the front through-lamp assembly 30 and the front end face of the front bumper bracket 20 so that the crumple space B is located behind the front through-lamp assembly 30 along the front and rear direction of the vehicle.

[0045] In this way, on the one hand, the front through-light assembly 30 is arranged on the front end surface of the front bumper bracket 20, and a collapse space B is formed between the front end surface. When pedestrians and the like collide with the front through-light assembly 30, the collapse space B can serve as a buffer and energy absorption space for the front through-light assembly 30, which is conducive to the release of the impact force and easy breakage of the front through-light assembly 30, and can reduce the damage caused by pedestrians and the like when they collide with the front through-light assembly 30. Therefore, this embodiment can improve the energy absorption and collapse capabilities of the front through-light assembly 30 when it is hit, thereby reducing the damage to pedestrians and the like. On the other hand, since the front through-light assembly 30 has the collapse capability, the decorative panel between the hood 40 and the front bumper 50 can be omitted, thereby improving the sealing and aesthetic performance of the front end of the vehicle.

[0046] In some embodiments, the front protection bracket 20 includes an upper support portion 21 and a lower support portion 22 that are interconnected, and the lower support portion 22 is protruding toward the front of the vehicle relative to the upper support portion 21 to form an installation position A; the front through-light assembly 30 includes: a light panel assembly 31 and a rear shell 32; the light panel assembly 31 is arranged on the front end surface of the rear shell 32, and the rear shell 32 is spaced apart from the front end surface of the upper support portion 21 to form a collapse space B.

[0047] Among them, when the vehicle is in use, the upper support portion 21 is arranged above the vehicle relative to the lower support portion 22, and the lower support portion 22 is arranged to protrude toward the front of the vehicle relative to the upper support portion 21; the front end face of the rear shell 32 refers to the side of the rear shell 32 facing the front of the vehicle when the vehicle is in use; the front end face of the upper support portion 21 refers to the side of the upper support portion 21 facing the front of the vehicle when the vehicle is in use.

[0048] Among them, the light board assembly 31 can include a front end plate 311 and a connecting plate 312, and the connecting plate 312 connects the front end plate 311 and the rear shell 32 respectively; a receiving cavity can also be formed between the front end plate 311 and the connecting plate 312 for installing other components of the light board assembly 31.

[0049] The front end plate 311 and the connecting plate 312 , and the connecting plate 312 and the rear shell 32 may be connected by welding or riveting.

[0050] The upper support portion 21 and the lower support portion 22 may be connected by welding or riveting, or may be integrally formed.

[0051] In this embodiment, the upper support portion 21 and the lower support portion 22 form the installation position A, which can limit the front through-lamp assembly 30 from the bottom and rear of the front through-lamp assembly 30, thereby improving its structural stability. The rear shell 32 can support and install the light board assembly 31, thereby improving its structural stability. In addition, in this embodiment, the front through-lamp assembly 30 is realized by the light board assembly 31 and the rear shell 32, and the structure is simple, which facilitates the thinning design of the structure of the front through-lamp assembly 30, thereby facilitating the expansion of the collapse space B behind the rear shell 32.

[0052] In some embodiments, the thinning of the front through-lamp assembly 30 can be achieved by compressing the glue groove and adjusting the mounting structure of the rear shell 32 .

[0053] In related technologies, such as Fig.17 As shown, the dimension of the front through-lamp assembly along the front-rear direction of the vehicle is L1; and in this application, as Fig.14 , 16 As shown, the angle between the front end plate 311, the connecting plate 312 and the rear shell 32 and the front-to-back direction as a whole increases, and the size of the front through-lamp assembly 30 along the front-to-back direction of the vehicle is significantly smaller than L1, so that a larger collapse space can be set behind the rear shell 32.

[0054] In some embodiments, the light board assembly 31 is protruded from the rear shell 32 at both ends in the first direction x, so that the front vehicle light assembly 60 arranged outside the two sides of the light board assembly 31 is spaced apart from the rear shell 32; wherein the first direction x is perpendicular to the collapse direction y.

[0055] Among them, the vehicle's front light assembly 60 and the front through-light assembly 30 are different components. The front light assembly 60 is used to provide the lights required for vehicle use, such as low beam lights, high beam lights, etc., while the front through-light assembly 30 is used to enhance the aesthetic effect of the vehicle, etc.

[0056] The first direction x may be the left-right direction of the vehicle, and the front lamp assembly 60 is disposed on the left and right sides of the front through-lamp assembly 30 .

[0057] Because the front vehicle lamp assembly 60 is arranged outside the two sides of the lamp panel assembly 31, and the rear shell 32 is spaced apart from the front vehicle lamp assembly 60 along the first direction x perpendicular to the collapse direction y, therefore, when the front through lamp assembly 30 is hit, that is, the lamp panel assembly 31 is hit, and the lamp panel assembly 31 and the rear shell 32 collapse backward along the collapse direction y, the interference between the front vehicle lamp assembly 60 and the lamp panel assembly 31 and the rear shell 32 can be reduced, which can not only improve the collapse ability of the front through lamp assembly 30 and reduce damage to pedestrians, but also reduce damage to the front vehicle lamp assembly 60.

[0058] The structures on both sides of the front through-light assembly 30 and the sides of the front vehicle lamp assembly 60 form an avoidance space to prevent the front through-light assembly 30 from being hit and moving backwards and interfering with the front vehicle lamp assembly 60 to affect the collapse stroke.

[0059] In some embodiments, a first connecting column 33 is provided through the rear end surface of the lamp assembly 30 , and the first connecting column 33 is connected to the front protection bracket 20 ; wherein the cross-sectional dimension of the first connecting column 33 decreases along the collapse direction y.

[0060] The rear end surface of the lamp assembly 30 refers to the side of the lamp assembly 30 facing the rear of the vehicle when the vehicle is in use. Specifically, the rear end surface of the rear shell 32 may form the first connecting column 33. The first connecting column 33 may be integrally formed with the rear shell 32 to improve structural stability.

[0061] On the one hand, the rear end surface of the through-lamp assembly 30 is connected to the front bumper bracket 20 through the first connecting column 33, which can expand the space of the collapse space B between the through-lamp assembly 30 and the front bumper bracket 20, and improve the collapse capability of the through-lamp assembly 30. On the other hand, the cross-sectional size of the first connecting column 33 decreases along the collapse direction y, which can reduce the force-bearing area of ​​the first connecting column 33 along the collapse direction y, thereby collecting and transmitting the external force on the through-lamp assembly 30 along the collapse direction y, so that the moment on the first connecting column 33 and / or the moment on the connection point of the front bumper bracket 20 is enlarged, so that the first connecting column 33 and / or the connection point of the front bumper bracket 20 are more likely to break, thereby improving the collapse capability of the through-lamp assembly 30.

[0062] The first connection column 33 can be integrally formed with the rear shell 32 .

[0063] In some embodiments, the front bumper bracket 20 is provided with a first mounting hole 23 , and the first connecting column 33 is at least partially located in the first mounting hole 23 ; wherein a first strength weakening structure 231 is provided in the peripheral area of ​​the first mounting hole 23 .

[0064] In this embodiment, the connection point where the front bumper bracket 20 connects to the first connection column 33 and the peripheral area of ​​the first mounting hole 23 are weakened, so that the connection point of the front bumper bracket 20 is easier to break, thereby improving the collapse capability of the front through-lamp assembly 30.

[0065] In some embodiments, the first strength weakening structure 231 may be a through hole and / or a weakened groove, which can reduce the structural strength at the connection point of the front guard bracket 20. The thickness of the weakened groove is less than the thickness of other positions of the front guard bracket 20.

[0066] The specific number, shape, arrangement, etc. of the first strength weakening structure 231 are not limited in the present application.

[0067] In some embodiments, the first strength weakening structure 231 may be realized by reducing the material strength of the peripheral area.

[0068] In some embodiments, an abutment member 331 is further provided at one end of the first connecting column 33 facing the front guard bracket 20, and the abutment member 331 can limit the axial position of the first connecting column 33 in the first mounting hole 23, and when the first connecting column 33 penetrates the lamp assembly 30 and collapses backward, after the front guard bracket 20 breaks, the damage caused by the first connecting column 33 to the front end module 70 located behind the front guard bracket 20 is reduced.

[0069] In some embodiments, a second connection column 34 is formed on the rear end face of the front through-lamp assembly 30, and the second connection column 34 is connected to the front bumper bracket 20 by welding or riveting. On the one hand, the rear end face of the through-lamp assembly 30 is connected to the front bumper bracket 20 through the second connection column 34, which can expand the space of the collapse space B between the through-lamp assembly 30 and the front bumper bracket 20 and improve the collapse capacity of the through-lamp assembly 30. On the other hand, the second connection column 34 can increase the connection stability between the front through-lamp assembly 30 and the front bumper bracket 20.

[0070] The second connecting column 34 is disposed closer to the middle of the front through-lamp assembly 30 relative to the first connecting column 33 .

[0071] The second connection column 34 can be integrally formed with the rear shell 32 .

[0072] In some embodiments, a corresponding strength weakening structure is provided in the peripheral area of ​​the connection point where the front protection bracket 20 connects to the second connection column 34, which can make the connection point easier to break, thereby improving the collapse capability of the front through-lamp assembly 30. The strength weakening structure can be a through hole and / or a weakening groove, etc.

[0073] In some embodiments, a connecting portion 35 is formed on the rear end surface of the front through-light assembly 30, and the connecting portion 35 is connected to the upper end surface of the front protection bracket 20; wherein the connecting portion 35 is provided with a second strength weakening structure 351. In this embodiment, the through-light assembly 30 can be partially carried on the upper end surface of the front protection bracket 20, specifically the upper end surface of the upper support portion 21, through the connecting portion 35, so that the weight of the through-light assembly 30 can be dispersed on the upper end surface of the upper support portion 21 and the upper end surface of the lower support portion 22, which can improve the stability of the structure. In addition, the second strength weakening structure 351 is provided on the connecting portion 35, which can make the connection easily break and produce relative displacement, thereby improving the collapse ability of the front through-light assembly 30.

[0074] The second strength weakening structure 351 may be a through hole and / or a weakening groove.

[0075] The specific number, shape, arrangement, etc. of the second strength weakening structure 351 are not limited in the present application.

[0076] The connection portion 35 may be integrally formed with the rear housing 32 .

[0077] In some embodiments, the upper end surface of the front bumper bracket 20 is further provided with a first limiting portion 24, and the connecting portion 35 is provided with a second limiting portion 352; the first limiting portion 24 and the second limiting portion 352 cooperate to limit the relative movement of the front bumper bracket 20 and the front through-light assembly 30 in a first plane; wherein, when the vehicle is in use, the first plane is a horizontal plane. In this embodiment, the front bumper bracket 20 and the front through-light assembly 30 are fixed in a horizontal plane by the first limiting portion 24 and the second limiting portion 352.

[0078] In some embodiments, the first limiting portion 24 is provided with a limiting hole, and the second limiting portion 352 is also provided with a limiting hole, and the limiting column is arranged in the two limiting holes to achieve the fixation of the two. Among them, the axial directions of the limiting hole and the limiting column are both arranged vertically to achieve the limiting in the horizontal plane. Of course, in other embodiments, the above-mentioned limiting can also be achieved by other structures.

[0079] In some embodiments, the upper end surface of the front protection bracket 20 is further provided with an abutment portion (not marked in the figure), and the first limiting portion 24 abuts against the abutment portion toward one end of the front protection bracket 20 to achieve pre-positioning along the collapse direction y.

[0080] In some embodiments, the front end surface of the front bumper bracket 20 is provided with a third limiting portion 25, and the front through-light assembly 30 is provided with a fourth limiting portion 36; the third limiting portion 25 and the fourth limiting portion 36 cooperate to at least limit the relative movement of the front bumper bracket 20 and the front through-light assembly 30 in a second plane; wherein, when the vehicle is in use, the second plane is a vertical plane. In this embodiment, the third limiting portion 25 and the fourth limiting portion 36 are used to achieve pre-positioning of the front bumper bracket 20 and the front through-light assembly 30 in a vertical plane.

[0081] The third limiting portion 25 can be specifically arranged on the upper end surface of the lower supporting portion 22 and located in the installation position A.

[0082] In some embodiments, the fourth limiting portion 36 includes a limiting groove, and the third limiting portion 25 includes a first rod body (not marked in the figure) and a second rod body (not marked in the figure) that are vertically connected to each other; the length direction of the first rod body is parallel to the collapse direction y of the front through-lamp assembly 30, and the length direction of the second rod body is parallel to the vertical direction. The first rod body is at least partially located in the limiting groove, and the end of the second rod body facing away from the first rod body is connected to the front protection bracket 20.

[0083] The second rod supports the first rod on the front through-lamp assembly 30 , and one end of the first rod facing away from the second rod is in limiting contact with the limiting groove.

[0084] One end of the second rod body facing away from the first rod body 251 is connected to the upper end surface of the lower support portion 22 of the front protection bracket 20 .

[0085] In some embodiments, the second rod is spaced apart from the front end surface of the upper support portion 21 to increase the possibility of the second rod being broken under the impact of the front penetrating lamp assembly 30 , thereby improving the collapse capability of the front penetrating lamp assembly 30 .

[0086] In some embodiments, other structures may be used to implement the fourth limiting portion 36 and the third limiting portion 25 .

[0087] In some embodiments, a connection bracket 26 is provided on the rear end face of the front bumper bracket 20, and is configured to be connected to the front end module 70 of the vehicle; wherein the connection bracket 26 is provided with a third strength weakening structure 261.

[0094] like Figures 1 to 7 As shown, the front bumper assembly of the present application further includes a front bumper skin 50, which is mounted on the front bumper bracket 20. The front bumper assembly also includes a front end module 70 and a windshield 90; the connecting bracket 26 of the rear end surface of the front bumper bracket 20 is connected to the front end module 70. The windshield 90 is connected to the front end module 70.

[0095] The present application further proposes a vehicle, such as Figures 1 to 7 As shown, the vehicle includes a hood 40 and a front bumper assembly; wherein the front through-light assembly 30 is disposed between the hood 40 and the front bumper 50. The hood 40 includes an outer shell 41 and an inner shell 42 disposed inside the outer shell 41. The outer shell 41 can be connected to the inner shell 42 and the front through-light assembly 30, and the inner shell 42 is also connected to the front bumper bracket 20. The specific structure of the front bumper assembly can be referred to the above embodiment, and will not be repeated here.

[0096] In some embodiments, the vehicle further includes a sealing assembly 80, which is at least disposed between the hood 40 and the front through-light assembly 30 to improve the sealing of the front end of the vehicle, thereby improving the reliability of the vehicle. Corresponding sealing members, such as sealing strips, can be disposed between the outer shell 41 and the front through-light assembly 30, and between the inner shell 42 and the front through-light assembly 30.

[0097] The front bumper assembly provided by the present application includes a front bumper bracket and a front through-light assembly, wherein the front end face of the front bumper bracket forms an installation position, and the front through-light assembly is arranged at the installation position and is spaced apart from the front end face of the front bumper bracket to form a collapse space of the front through-light assembly. In this way, on the one hand, the front through-light assembly is arranged at the front end face of the front bumper bracket, and a collapse space is formed between the front end face, and when pedestrians and the like collide with the front through-light assembly, the collapse space can serve as a buffer and energy absorption space for the front through-light assembly, which is conducive to the release of the impact force and easy fracture of the front through-light assembly, and can reduce the damage caused by pedestrians and the like when they collide with the front through-light assembly. Therefore, the present application can improve the energy absorption and collapse capabilities of the front through-light assembly when it is impacted, thereby reducing the damage to pedestrians and the like. On the other hand, since the front through-light assembly has the collapse capability, the decorative plate between the hood and the front bumper can be omitted, thereby improving the sealing and aesthetic properties of the front end of the vehicle.

[0098] The present application adjusts the structure of the front through-light assembly and weakens the front bumper bracket accordingly, designs an avoidance space in the direction of force transmission, that is, the direction of collapse, so that the front through-light assembly collapses backwards when a collision occurs, thereby achieving the purpose of reducing the thigh injury value of pedestrians when a vehicle collides with pedestrians.

[0099] The present application can solve the problem that for vehicles with low front ends, the assembly method in which the hood and the front through-light assembly are directly matched is difficult to meet the pedestrian protection requirements; and compared with methods such as adding airbags to the front face of the vehicle to reduce pedestrian injuries, the present application has low cost and high maintainability.

[0100] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
