Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicle headlights, and in particular to a headlight mask, a headlight assembly and a vehicle front end structure. Background Art
[0002] In recent years, with the continuous improvement of national consumption levels, the number of domestic vehicles has increased year by year, resulting in an increase in the number of accidents involving vehicle-pedestrian collisions. Therefore, improving the protection of vulnerable groups and pedestrians on the road has become an important goal and topic of current laws and regulations and passive safety development technologies.
[0003] China's mandatory regulation GB24550 "Vehicle-to-Pedestrian Collision Protection" has been released. For new application forms of approved models, it will be implemented from January 1, 2025, and for approved models, it will be implemented from the 25th month after the implementation of this document. It clearly explains the impact protection of pedestrians' legs, and stipulates the limit requirements for the bending moment and impact force on the legs and the extension of the ligaments. If the injury index exceeds a certain range, it will not meet this law and regulations, and the vehicle will not be able to be put on the market. In addition, the world's most advanced and comprehensive vehicle safety evaluation organizations such as C-NCAP (China New Car Assessment Program Pedestrian Protection Test Program), C-IASA (China Insurance Vehicle Safety Index Program), and Euro NCAP (European New Car Assessment Program) have also included protection for vulnerable groups and pedestrians on the road. If a vehicle cannot protect pedestrians well (for example, it cannot get a good score in the head and leg collision conditions), the vehicle will not be able to get the highest level of safety evaluation.
[0004] At present, when a vehicle headlight mask collides with a pedestrian, the headlight mask has a large rigidity, which easily causes the pedestrian's femur and / or hip fracture. Therefore, how to reduce the damage to the pedestrian when the headlight mask collides with the pedestrian is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention
[0005] In view of the above, it is necessary to propose a headlight mask, a headlight assembly and a vehicle front end structure to reduce the damage to pedestrians when colliding with pedestrians.
[0006] An embodiment of the present application provides a headlight cover, comprising: a first cover body, wherein a material thickness in a middle area of the first cover body is greater than a material thickness in a peripheral area of the first cover body, and the material thickness of the first cover body gradually becomes thinner from the middle area of the first cover body to the peripheral area of the first cover body.
[0007] The headlight mask of the embodiment of the present application is configured such that the material thickness of the first cover body gradually becomes thinner from the middle area of the first cover body to the peripheral area of the first cover body, thereby forming a thickness gradient or a stiffness gradient on the first cover body. When the headlight mask collides with a pedestrian, the first cover body is easily broken from the edge when subjected to force, and the impact force transmitted to the pedestrian by the headlight mask will be sharply reduced, thereby reducing the damage to the pedestrian when the headlight mask collides with the pedestrian.
[0008] In some embodiments, the first cover body has a first surface and a second surface that are oppositely arranged, the first surface is located on the outside of the first cover body, and the second surface is located on the inside of the first cover body. The headlight cover also includes a second cover body, which is protruding from the middle of the first surface and connected to the second surface. The material thickness of the second cover body is greater than or equal to the material thickness of the middle area of the first cover body.
[0009] By setting the second cover, it is convenient to store the lighting module of the headlight assembly. By setting the material thickness of the second cover to be greater than or equal to the material thickness of the middle area of the first cover, the second cover will basically not break when it collides with a pedestrian, and can quickly transfer the impact force to the first cover to break the first cover, which is beneficial to reduce the damage to the pedestrian when the headlight mask collides with the pedestrian. In addition, the second cover is the area that is directly in contact with the external environment. By setting the material thickness of the second cover to be greater than or equal to the material thickness of the middle area of the first cover, the second cover is not easily damaged by pressing or slight collision, which is beneficial to increase the service life of the headlight mask and enable the second cover to effectively protect the lighting module.
[0010] In some embodiments, the first cover body is made of light-shielding material, and the second cover body is made of light-transmitting material.
[0011] By setting the first cover body to be made of a light-shielding material, the light of the lighting module can be shielded to prevent the light of the lighting module from irradiating the bumper to form a light spot and affecting the appearance of the vehicle. By setting the second cover body to be made of a light-transmitting material, the light of the lighting module can be emitted through the second cover body to the outside of the bumper for illumination.
[0012] In some embodiments, the first surface is convexly provided with a first boss, and the first boss is located between the edge of the first cover body and the second cover body.
[0013] By providing the first boss, when the headlight mask does not collide with a pedestrian, the first boss abuts against the inner side of the bumper and supports the bumper, so that the bumper is not easily deformed when subjected to pressure such as pressing, thereby improving the rigidity of the bumper and the user's experience. When the headlight mask collides with a pedestrian, since the first boss is located between the edge of the first cover body and the second cover body, when the force propagates from the middle area of the first cover body to the edge, the first boss forms a stress concentration area on the first cover body, thereby increasing the possibility and degree of fragmentation of the first cover body, which is conducive to reducing the damage to pedestrians when the headlight mask collides with pedestrians.
[0014] In some embodiments, along the direction from the second surface to the first surface, the size of the cross section of the first boss gradually decreases, and the first boss has a supporting surface on a side away from the first surface.
[0015] By gradually reducing the cross-sectional size of the first boss, it is convenient for the first boss to concentrate stress and form a stress concentration area on the first cover body. By setting a supporting surface on the side of the first boss away from the first surface, it is beneficial to ensure the contact area between the first boss and the bumper, thereby facilitating improving the stability of the first boss supporting the bumper.
[0016] In some embodiments, a second boss is further provided on the first surface, and the second boss is connected to a side of the second cover body close to the first boss and is spaced apart from the first boss.
[0017] By setting the second boss, when the first cover body is broken under the action of impact force, due to the stress guided by the second boss, the rupture area of the first cover body includes the edge of the first cover body and the part of the first cover body located between the first boss and the second boss, thereby increasing the area of the rupture area of the first cover body, which is beneficial to reduce the damage to pedestrians when the headlight mask collides with pedestrians.
[0018] In some embodiments, the headlight cover further includes a plurality of clips, and the plurality of clips are arranged at intervals on the first surface and around the second cover body.
[0019] By providing the snap-in piece, it is convenient to snap-in with the bumper through the snap-in piece, thereby facilitating the convenience and stability of the connection between the headlight mask and the bumper.
[0020] In some embodiments, the periphery of the first cover body is provided with a convex edge extending outward, and the periphery of the first cover body is also provided with a positioning protrusion and a snap-on protrusion, and the positioning protrusion and the snap-on protrusion are both located on the side of the convex edge away from the first surface.
[0021] When the first cover is connected to the housing of the headlight assembly, the convex edge abuts against the edge of the housing, so that the first cover is supported at the opening of the housing, thereby effectively preventing the headlight cover from moving into the housing when hit and damaging the components in the headlight assembly. The positioning protrusion is inserted into the housing of the headlight assembly to position the first cover relative to the housing, and the buckle protrusion is snap-fitted with the housing of the headlight assembly, which is conducive to improving the convenience and accuracy of connecting the first cover to the housing of the headlight assembly.
[0022] The embodiment of the present application also provides a headlight assembly, including the headlight mask as described above.
[0023] The headlight assembly of the embodiment of the present application is provided with a headlight mask, which helps to reduce the damage to pedestrians when the headlight assembly collides with pedestrians through the headlight mask.
[0024] The embodiment of the present application also provides a vehicle front end structure, including the headlight assembly as described above.
[0025] The front end structure of the vehicle in the embodiment of the present application is provided with a headlight assembly including the above-mentioned headlight mask, which is beneficial to reducing the damage to pedestrians when the front end structure of the vehicle collides with pedestrians through the headlight mask.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0035] See also Figure 1 and Figure 4 The embodiment of the present application provides a headlight mask 100 applied to a headlight assembly 1 . The headlight mask 100 includes a first cover body 10 .
[0036] The material thickness of the middle area of the first cover body 10 is greater than the material thickness of the peripheral area of the first cover body 10 , and the material thickness of the first cover body 10 gradually becomes thinner from the middle area of the first cover body 10 to the peripheral area of the first cover body 10 .
[0037] When the headlight mask 100 collides with a pedestrian, since the material thickness of the first cover body 10 gradually becomes thinner from the middle area of the first cover body 10 to the peripheral area of the first cover body 10, a thickness gradient or a stiffness gradient is formed on the first cover body 10. In this way, the first cover body 10 is easily broken from the edge when subjected to force. When the first cover body 10 is broken, the impact force transmitted to the pedestrian by the headlight mask 100 will be sharply reduced, thereby reducing the damage to the pedestrian when the headlight mask 100 collides with the pedestrian.
[0038] See also Figure 1 and Figure 2 In this embodiment, the first cover body 10 has a first surface 11 and a second surface 12 which are arranged opposite to each other, the first surface 11 is located on the outside of the first cover body 10, and the second surface 12 is located on the inside of the first cover body 10. The headlight cover 100 also includes a second cover body 20, which is convexly arranged in the middle of the first surface 11 and communicates with the second surface 12, and the material thickness of the second cover body 20 is greater than or equal to the material thickness of the middle area of the first cover body 10.
[0039] Please refer to Figure 4 and Figure 5 Specifically, the first cover 10 is used to connect with the housing 200 of the headlight assembly 1, the first surface 11 is located on the side of the first cover 10 away from the housing 200, and the second cover 20 is provided with a storage groove 21 extending to the second surface 12, and the lighting module of the headlight assembly 1 (not shown) extends into the storage groove 21, so that the second cover 20 can store the lighting module of the headlight assembly 1. During installation, a through hole 310 is provided on the bumper 300 of the vehicle (not shown), the first cover 10 is located on the inner side of the bumper 300, and the second cover 20 passes through the bumper 300 and protrudes from the outer side of the bumper 300.
[0040] When the headlight mask 100 collides with a pedestrian, since the second cover body 20 protrudes from the outside of the bumper 300, the second cover body 20 is the contact area between the headlight mask 100 and the pedestrian. Under the impact of the pedestrian, the second cover body 20 applies a force to the first cover body 10, thereby breaking the first cover body 10 from the edge.
[0041] In this way, by setting the second cover 20, it is convenient to store the lighting module of the headlight assembly 1. By setting the material thickness of the second cover 20 to be greater than or equal to the material thickness of the middle area of the first cover 10, the second cover 20 will basically not break when it collides with a pedestrian, and can quickly transfer the impact force to the first cover 10 to break the first cover 10, thereby helping to reduce the damage to the pedestrian when the headlight mask 100 collides with the pedestrian. In addition, the second cover 20 is the area directly in contact with the external environment. By setting the material thickness of the second cover 20 to be greater than or equal to the material thickness of the middle area of the first cover 10, the second cover 20 is not easily damaged when pressed or slightly collided, thereby helping to increase the service life of the headlight mask 100 and enable the second cover 20 to effectively protect the lighting module.
[0042] In this embodiment, the material thickness of the middle area of the first cover body 10 ranges from 2.2mm to 3mm, and the material thickness of the peripheral area of the first cover body 10 ranges from 1.5mm to 2mm, so that the material thickness of the first cover body 10 is moderate and easy to break when impacted.
[0043] In this embodiment, the material thickness of the second cover body 20 is in the range of 3 mm-3.5 mm, so that the second cover body 20 has a suitable thickness and is conducive to improving the structural strength of the second cover body 20.
[0044] In this embodiment, the first cover 10 is made of a light-shielding material, so that the light of the lighting module can be shielded to prevent the light of the lighting module from irradiating the bumper 300 to form a light spot and affect the appearance of the vehicle. The second cover 20 is made of a light-transmitting material, so that the light of the lighting module can be emitted through the second cover 20 to the outside of the bumper 300 for illumination.
[0045] In this embodiment, the first cover body 10 and the second cover body 20 can be molded into an integral structure by a two-color injection molding process. The first cover body 10 is molded in black to facilitate light shielding, and the second cover body 20 is molded in a transparent state to facilitate light transmission. In addition, the first cover body 10 and the second cover body 20 are an integral injection molding structure, which is convenient for installing the headlight cover 100, and convenient for quickly transferring the impact force from the second cover body 20 to the first cover body 10 when the second cover body 20 is hit, and the injection molded parts are easy to break when hit, which is conducive to reducing the damage to pedestrians when the headlight cover 100 collides with pedestrians.
[0046] In some other embodiments, the first cover body 10 and the second cover body 20 may also be split structures, such as the second cover body 20 is detachably mounted on the first cover body 10 by bolts (not shown), which is not specifically limited in the embodiments of the present application.
[0047] In this embodiment, the notch of the storage groove 21 extends outward to form a support step 22 . The support step 22 supports the lighting module when the lighting module extends into the storage groove 21 , thereby facilitating improving the stability of the lighting module when it is stored in the second cover body 20 .
[0048] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, the first surface 11 is provided with a first boss 13, and the first boss 13 is located between the edge of the first cover body 10 and the second cover body 20. The first boss 13 is used to form a stress concentration area on the first cover body 10 when the second cover body 20 is impacted, so as to break the first cover body 10, and the first boss 13 is also used to abut against the inner side of the bumper 300 to support the bumper 300.
[0049] Specifically, when the headlight mask 100 does not collide with a pedestrian, the first boss 13 abuts against the inner side of the bumper 300 and supports the bumper 300, so the bumper 300 is not easily deformed when pressed or subjected to pressure, thereby improving the rigidity of the bumper 300 and the user's experience. When the headlight mask 100 collides with a pedestrian, since the first boss 13 is located between the edge of the first cover body 10 and the second cover body 20, when the impact force propagates from the middle area of the first cover body 10 to the edge, the first boss 13 forms a stress concentration area on the first cover body 10, thereby increasing the possibility and degree of fragmentation of the first cover body 10, which is conducive to reducing the damage to pedestrians when the headlight mask 100 collides with pedestrians.
[0050] In this embodiment, the size of the cross section of the first boss 13 gradually decreases along the direction from the second surface 12 toward the first surface 11, and the first boss 13 has a support surface 131 on the side away from the first surface 11, and the support surface 131 is used to abut against the inner side of the bumper 300 to support the bumper 300. By setting the size of the cross section of the first boss 13 to gradually decrease, it is convenient for the first boss 13 to concentrate stress and form a stress concentration area on the first cover 10, and by providing the support surface 131 on the side of the first boss 13 away from the first surface 11, it is helpful to ensure the contact area between the first boss 13 and the bumper 300, thereby facilitating the stability of the first boss 13 supporting the bumper 300.
[0051] In this embodiment, the first boss 13 is provided with a groove 132 extending to the second surface 12 , which is helpful to reduce the weight of the headlight cover 100 and to form a stress concentration area on the first cover body 10 by the first boss 13 .
[0052] In this embodiment, the material thickness of the first boss 13 is the same as the material thickness of the middle area of the first cover body 10 , thereby facilitating the integral injection molding of the first boss 13 and the first cover body 10 and facilitating improving the structural strength of the first boss 13 .
[0053] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the first surface 11 is further provided with a second boss 14, which is connected to a side of the second cover 20 close to the first boss 13 and is spaced apart from the first boss 13. When the first cover 10 is broken under the impact force, since the second boss 14 guides the stress, the rupture area of the first cover 10 includes the edge of the first cover 10 and the part of the first cover 10 between the first boss 13 and the second boss 14, thereby increasing the area of the rupture area of the first cover 10, which is beneficial to reduce the damage to pedestrians when the headlight cover 100 collides with pedestrians.
[0054] In this embodiment, the second boss 14 is roughly trapezoidal and is located on one side of the first boss 13. The height of the second boss 14 is less than that of the first boss 14. An injection port 141 is provided on the second boss 14. When the headlight cover 100 is injection-molded, the injection mold (not shown) injects glue through the injection port 141 to inject the headlight cover 100.
[0055] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, the headlight cover 100 further includes a plurality of snap-fitting members 30, which are arranged at intervals on the first surface 11 and around the second cover body 20. The plurality of snap-fitting members 30 are used to snap-fit with the bumper 300, thereby facilitating the convenience and stability of the connection between the headlight cover 100 and the bumper 300.
[0056] In this embodiment, the multiple clips 30 include multiple first clips 31 and multiple second clips 32. The first clips 31 are protruding structures, and the second clips 32 are snap ring structures. When the headlight mask 100 is connected to the bumper 300, the first clips 31 are inserted into the slots (not shown) of the bumper 300 and snap into place with the slots, and the second clips 32 are snap into place with the hooks (not shown) of the bumper 300. This further helps to improve the convenience and stability of the connection between the headlight mask 100 and the bumper 300.
[0057] In this embodiment, the headlight cover 100 further includes a plurality of positioning members 40, which are arranged at intervals on the first surface 11 and around the second cover 20. When the headlight cover 100 is connected to the bumper 300, the plurality of positioning members 40 are inserted into the bumper 300 to position the first cover 10 and the second cover 20 relative to the bumper 300, thereby facilitating the accuracy of the connection between the headlight cover 100 and the bumper 300.
[0058] In this embodiment, the first surface 11 is further provided with a plurality of limiting grooves 111, and the plurality of limiting grooves 111 are arranged at intervals around the second cover body 20. When the headlight cover 100 is connected to the bumper 300, the protruding portion of the bumper 300 is inserted into the limiting grooves 111 to position the first cover body 10 and the second cover body 20 relative to the bumper 300, thereby further facilitating the accuracy of the connection between the headlight cover 100 and the bumper 300.
[0059] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the periphery of the first cover 10 is provided with a convex edge 15 extending outward, and the periphery of the first cover 10 is also provided with a positioning protrusion 17 and a buckle protrusion 18, both of which are located on the side of the convex edge 15 away from the first surface 11. When the first cover 10 is connected to the housing 200 of the headlight assembly 1, the convex edge 15 abuts against the edge of the housing 200, so that the first cover 10 is supported at the opening of the housing 200, thereby effectively preventing the headlight cover 100 from moving into the housing 200 when impacted and damaging the components in the headlight assembly 1. The positioning protrusion 17 is used to insert into the housing 200 of the headlight assembly 1 to position the first cover 10 relative to the housing 200, and the buckle protrusion 18 is used to snap with the housing 200 of the headlight assembly 1, so as to improve the convenience and accuracy of connecting the first cover 10 with the housing 200 of the headlight assembly 1.
[0060] In this embodiment, the periphery of the first cover body 10 is bent toward the inside of the first cover body 10 to form a bent portion 16, and the convex edge 15, the positioning protrusion 17 and the buckling protrusion 18 are all convexly arranged on the outer peripheral side of the bent portion 16. When the first cover body 10 is connected to the housing 200 of the headlight assembly 1, the bent portion 16 is inserted into the opening of the housing 200 and abuts against the inner wall of the opening, thereby limiting the shaking of the first cover body 10 relative to the housing 200, which is beneficial to improve the stability of the connection between the first cover body 10 and the housing 200 of the headlight assembly 1.
[0061] In this embodiment, a plurality of spaced reinforcing ribs 19 are convexly disposed on the inner side of the bending portion 16 . The reinforcing ribs 19 are provided to improve the structural strength of the bending portion 16 and reduce the probability of the bending portion 16 being warped.
[0062] In this embodiment, a plurality of spaced connection posts 50 are protruded from the second surface 12, and threaded holes 51 are formed on the connection posts 50. After the first cover 10 is connected to the housing 200 of the headlight assembly 1, the corresponding part of the headlight assembly 1 is connected to the threaded hole 51 by screws (not shown), which is conducive to improving the stability and firmness of the installation of the headlight cover 100.
[0063] In summary, the headlight mask 100 of the embodiment of the present application is configured such that the material thickness of the first cover body 10 gradually becomes thinner from the middle area of the first cover body 10 to the peripheral area of the first cover body 10, thereby forming a thickness gradient or a stiffness gradient on the first cover body 10. When the headlight mask 100 collides with a pedestrian, the first cover body 10 is easily broken from the edge by the force, and the impact force transmitted to the pedestrian by the headlight mask 100 will be sharply reduced, thereby reducing the damage to the pedestrian when the headlight mask 100 collides with the pedestrian. By providing the first boss 13, the bumper 300 can be supported, thereby improving the stiffness of the bumper 300 and the user's experience. In addition, the first boss 13 can also form a stress concentration area on the first cover body 10, thereby increasing the possibility and degree of fragmentation of the first cover body 10, which is conducive to reducing the damage to the pedestrian when the headlight mask 100 collides with the pedestrian.
[0064] Please refer to Figure 4 The embodiment of the present application also provides a headlight assembly 1, and the headlight assembly 1 includes the headlight mask 100 as described above.
[0065] The headlight assembly 1 of the embodiment of the present application is provided with a headlight cover 100, which is helpful to reduce the damage to pedestrians when the headlight assembly 1 collides with pedestrians through the headlight cover 100.
[0066] In this embodiment, the headlight assembly 1 further includes a housing 200 and a lighting module (not shown), the headlight cover 100 is disposed at the opening of the housing 200 , and the lighting module is installed in the housing 200 and extends into the second cover body 20 .
[0067] Please refer to Figure 5 The embodiment of the present application also provides a vehicle front end structure 1000, which includes the headlight assembly 1 as described above. Since the headlight assembly 1 includes the headlight mask 100 as described above, the damage to pedestrians caused by the vehicle front end structure 1000 when colliding with pedestrians through the headlight mask 100 is reduced.
[0068] In this embodiment, the vehicle front end structure 1000 also includes a bumper 300 and an engine cover 400. The bumper 300 is installed in front of the engine cover 400. The bumper 300 is provided with a through hole 310. The headlight assembly 1 is installed on the inner side of the bumper 300 and is rigidly connected to the vehicle (not shown) through a mounting foot (not shown). The second cover body 20 of the headlight mask 100 passes through the through hole 310 and extends to the outside of the bumper 300. The first boss 13 of the headlight mask 100 abuts against the inner side of the bumper 300.
[0069] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application.
