When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0051] With the continuous development of the automotive industry in recent years, the pursuit of automotive styling has become more and more diverse. The main engine factory improves the diversity of the overall front styling by adding a through headlight or a through decorative panel at the front, which leads to an increase in the number of matching parts and makes it easier to have problems with pedestrian protection not meeting the standards.

[0052] In the traditional matching structure, in order to meet the regulatory requirements for pedestrian protection, the self-strength of the front parts is usually reduced to ensure the collapse of the front parts after a collision, which easily leads to problems such as abnormal noises during part contact and durability failure due to the weak self-strength of the parts, and optimization is required.

[0053] The front-end assembly of a vehicle includes structures such as a front-end module, an upper front bumper support frame, a middle front bumper support frame, a front bumper body, a lower front bumper decorative panel, and a lower front bumper guard plate. Among them, the front-end module, the upper front bumper support frame, the middle front bumper support frame, and the front bumper body are the main frame structures of the front-end assembly. When the vehicle is impacted in the front-rear direction, the impact force is mainly conducted from the front bumper body to the upper front bumper support frame, and then to the front-end module.

[0054] In one embodiment, a crush energy absorption structure is provided on the upper front bumper support frame, or a crush energy absorption structure is provided on the connection structure between the upper front bumper support frame and the front-end module. The crush energy absorption structure is some relatively weakened structures that are easily deformed by force to absorb energy.

[0055] Hereinafter, the vehicle itself is used as a coordinate reference to describe the structure. For example, the front of the vehicle is the front, the rear of the vehicle is the rear, the roof is the upper, the vehicle floor is the lower, and the two sides of the vehicle body are the left-right direction.

[0056] The present utility model provides an upper front bumper support frame 100, which includes a bracket body 110, an insertion portion 120, and a limiting structure 130. The insertion portion 120 is provided on the bracket body 110 for plugging and mating with a socket portion 210 provided on the front-end module 200.

[0057] The limiting structure 130 is provided on the insertion portion 120 to limit the upper front bumper support frame 100 and the front-end module 200 at least in two different directions, and during the process of the upper front bumper support frame 100 and the front-end module 200 moving towards each other, it can crush and absorb energy in at least the two different directions.

[0058] In the technical solution of the present utility model, the upper front bumper support frame 100 and the front-end module 200 are plugging and mating. The setting of the limiting structure 130 enables the upper front bumper support frame 100 and the front-end module 200 to be limited at least in two different directions, and during the process of the upper front bumper support frame 100 and the front-end module 200 moving towards each other, it can crush and absorb energy in at least the two different directions. Limiting the upper front bumper support frame 100 and the front-end module 200 in different directions ensures the effective limitation of the two parts and avoids abnormal noise problems and durability failure problems of the two parts during vehicle driving. During the process of the upper front bumper support frame 100 and the front-end module 200 moving towards each other, it can crush and absorb energy in at least the two different directions, realizing effective sliding after a frontal collision, thereby reducing impact energy and improving the safety of pedestrian protection.

[0059] It should be noted that the at least two different directions are arranged at an included angle, which can be an acute angle or an obtuse angle. In one embodiment, the at least two different directions are perpendicular to each other. For example, it can be the front-back direction and the up-down direction; it can also be the front-back direction and the left-right direction; it can also be the up-down direction and the left-right direction; or it can be the three directions of the front-back direction, the up-down direction and the left-right direction.

[0060] In the embodiments of the present utility model, the specific structural forms of the insertion part 120 and the socket part 210 are not limited. In the insertion part 120 and the socket part 210, one can be set as a convex part and the other can be set as a concave part. As long as they can be plugged and matched with each other, they are all within the protection scope of the present utility model. Adopting the plugging and matching method is beneficial to the sliding guidance of the front bumper upper support frame 100 and the front end module 200 after a collision.

[0061] In one embodiment, the insertion part 120 is set as an insertion convex part, and the socket part 210 is set as a socket concave part. The cross-sectional shapes of the two are not limited, and can be rectangular, square or circular, etc.

[0062] In addition, for the convenience of plugging and matching, the insertion convex part is set to have a variable cross-sectional shape. For example, the cross-section of the head of the insertion convex part is set to be smaller than the cross-section of the root of the insertion convex part and changes gradually, so that when assembling the front end module 200 and the front bumper upper support frame 100, the insertion convex part can be well introduced into the socket concave part.

[0063] In one embodiment, the limiting structure 130 includes a first convex part 131 provided at the side end of the insertion convex part. The first convex part 131 is used to abut against the edge of the socket concave part provided on the front end module 200. The first convex part 131 can be bent and deformed and collapsed in the front-back direction. That is, the setting method of the first convex part 131 abutting against the edge of the socket concave part realizes the limitation of the front bumper upper support frame 100 and the front end module 200 in the front-back direction; the first convex part 131 can be bent and deformed and collapsed in the front-back direction, realizing the collapse in the front-back direction and the effective sliding after a front-side collision, thereby reducing the impact energy.

[0064] For the first convex part 131, the first convex part 131 is the collapse structure. The protruding length of the first convex part 131 is not limited, as long as it can abut against the edge of the socket concave part; nor is the specific cross-sectional shape of the first convex part 131 limited, and it can be rectangular, square or circular. Of course, no matter how it is set, it is preferably to set the end surface abutting against the edge of the socket concave part as a plane. In this way, during the abutting process, the two abutting against each other are in contact with two planes, with a large contact area and uniform force.

[0065] In some embodiments, the first convex portion 131 is provided in a long strip shape, i.e., a plate-like structure. The plate-like structure forms a cantilever, which is prone to deformation at one end of the suspension and has a good energy absorption effect.

[0066] The first convex portion 131 may be only a structure provided in a straight strip shape. Such a structure has relatively weak strength and is prone to deformation and collapse after a minor collision. In some embodiments, one end of the first convex portion 131 is provided on the insertion convex portion, and the other end is bent from front to back. That is, by providing a bending section on the first convex portion 131, the structural strength of the suspended end of the first convex portion 131 is strengthened, so that the deformation of the first convex portion 131 occurs as much as possible in the scenario of an effective collision.

[0067] In embodiments where the insertion convex portion is provided with a rectangular cross-section or a square cross-section, the insertion convex portion has a plurality of side end portions, such as a left side end portion, a right side end portion, a front side end portion, a rear side end portion, and so on. The first convex portion 131 may be provided on any one of the above side end portions. It should be noted that the setting of the first convex portion 131 needs to be staggered from other structures, such as the limiting structure 130 in another direction, etc. The above two limiting structures 130 are provided corresponding to different side end portions of the insertion convex portion.

[0068] In order to facilitate the deformation of the first convex portion 131 in a suitable scenario, in one embodiment, the first convex portion 131 is inclined, and its inclination direction is set to be away from the head of the insertion convex portion from front to back. By setting the first convex portion 131 as an inclined plate member in a long strip shape, after the front bumper upper support frame 100 collides, the interference amount gradually increases during the backward movement process, forming a gradually energy-absorbing state.

[0069] After the collapse structure collapses, it is necessary not to affect or reduce the sliding connection between the front bumper upper support frame 100 and the front end module 200 in the front-rear direction. The collapse structure can be retracted or turned outwards. In some embodiments, the insertion convex portion is provided in a hollow shape, and an avoidance opening 121 is provided at the side end portion of the insertion convex portion. The first convex portion 131 is provided at the edge of the avoidance opening 121. That is, after the first convex portion 131 deforms, at least part of it can be received in the hollow inner cavity of the insertion convex portion, reducing the influence on the guiding and sliding of the front bumper upper support frame 100 and the front end module 200.

[0070] It should be noted that the set width of the avoidance opening 121 needs to be greater than the width of the first convex portion 131, and the length also needs to be greater than the length of the first convex portion 131, so as to be able to well accommodate the deformed first convex portion 131.

[0071] In addition, a plurality of the first convex portions 131 may be provided, respectively provided on a plurality of side end portions of the insertion convex portion. Of course, a plurality of the first convex portions 131 may also be provided on one side end portion of the insertion convex portion.

[0072] In some embodiments, the insertion portion 120 is provided as an insertion convex portion extending in the front-rear direction. The insertion convex portion has a plurality of side end portions, and the plurality of side end portions include a first side end portion and a second side end portion opposite to the first side end portion. The limiting structure 130 includes a second convex portion 132 provided on the first side end portion of the insertion convex portion. In the direction from front to rear, the protruding height of the second convex portion 132 is gradually increased, so that the second side end portion of the insertion convex portion abuts against a corresponding elastic arm 211 provided on the socket portion 210, so that the elastic arm 211 can be bent and deformed and collapsed in the up-down direction or the left-right direction. That is, for the elastic arm 211, the elastic arm 211 is turned outwards and deformed, and the elastic arm 211 is a collapse structure. Through the arrangement of the elastic arm 211 and the second convex portion 132, the front bumper upper support frame 100 and the front end module 200 are limited in the up-down direction or the left-right direction; the second convex portion 132 can be bent and deformed and collapsed in the up-down direction or the left-right direction, realizing collapse in the up-down direction or the left-right direction, and can effectively slide after a front-side collision, thereby reducing the impact energy.

[0073] The second convex portion 132 may be provided in the form of a rib, such as a rib with a larger width at one end and a smaller width at the other end. By vertically installing the rib, the elastic arm 211 can be lifted outwards during the contact process between the second convex portion 132 and the edge of the socket recess, so as to realize the collapse of the elastic arm 211.

[0074] A plurality of the second convex portions 132 may be provided and are spaced apart in the width direction of the side end portion of the insertion convex portion.

[0075] In the embodiments of the present invention, the specific setting position of the second convex portion 132 is not limited. For example, the second convex portion 132 may be provided at the side end portion of the insertion convex portion in the left-right direction. At this time, the elastic arm 211 can be bent and deformed and collapsed in the left-right direction; it may also be that the second convex portion 132 is provided at the side end portion of the insertion convex portion in the up-down direction. At this time, the elastic arm 211 can be bent and deformed and collapsed in the up-down direction.

[0076] It should be noted that the side end of the second convex portion 132 provided on the insertion convex portion needs to be staggered from the position of the side end of the first convex portion 131 provided on the insertion convex portion. In some embodiments, the first convex portion 131 is provided at the side end of the insertion convex portion in the left-right direction, and the second convex portion 132 is provided at the side end of the insertion convex portion in the up-down direction.

[0077] The settings of the first convex portion 131, the second convex portion 132, and the elastic arm 211 limit the relative movement of the front bumper upper support frame 100 and the front end module 200. In an embodiment for limiting the relative movement of the front bumper upper support frame 100 and the front end module 200 away from each other, the limiting structure 130 includes a clamping structure 140. The clamping structure 140 includes a clamping arm 141 and a clamping projection 142. The clamping arm 141 is provided at the side end of the insertion convex portion and extends in the front-rear direction; the clamping projection 142 is provided at the free end of the clamping arm 141 for clamping and cooperating with a clamping and mating portion 213 provided on the front end module 200. Through the clamping of the clamping projection 142 and the clamping and mating portion 213, the relative movement of the front bumper upper support frame 100 and the front end module 200 away from each other is limited.

[0078] The clamping arm 141 is formed by providing a cut groove on the insertion convex portion, so that the clamping arm 141 has elasticity and can deform to a certain extent to achieve the clamping of the clamping projection 142 and the clamping and mating portion 213.

[0079] The present utility model also proposes a front end assembly 1000, which includes a front end module 200 and a front bumper upper support frame 100. The front end module 200 is provided with a socket portion 210, and the insertion portion 120 of the front bumper upper support frame 100 is inserted and mated with the socket portion 210. The front end assembly 1000 includes all the technical solutions of all the embodiments of the above-mentioned front bumper support frame, and therefore also has the technical effects brought by the above technical solutions, which will not be elaborated here one by one.

[0080] Inside the front end assembly 1000, the front end module 200 is connected to the front bumper upper support frame 100. In the front bumper upper support frame 100, the insertion portion 120 is provided as an insertion convex portion extending in the front-rear direction. The insertion convex portion has a plurality of side ends, and the plurality of side ends include a first side end and a second side end opposite to the first side end. The limiting structure 130 includes a second convex portion 132 provided on the first side end of the insertion convex portion. In the direction from front to back, the protruding height of the second convex portion 132 is gradually increasing.

[0081] In the front-end module 200, the socket part 210 is provided with a socket groove having an opening on one side in the front-rear direction. An elastic arm 211 is formed on the groove wall of the socket groove opposite to the second side end of the insertion convex part. During the opposite movement of the front bumper upper support frame 100 and the front-end module 200, the insertion convex part abuts against the elastic arm 211, so that the elastic arm 211 is bent and deformed and collapsed in the up-down direction or the left-right direction. That is, the collapse structure is arranged in the socket part 210 of the front-end module 200. After the insertion part 120 is inserted into the socket part 210, the elastic arm 211 is bent outwardly to strain and absorb energy.

[0082] The elastic arm 211 may be a structure formed after being partially hollowed out. Specifically, two cutouts 212 are provided on the groove wall of the socket groove opposite to the second side end of the insertion convex part. One end of each cutout 212 communicates with the opening of the socket groove, and the other ends are arranged at intervals. The elastic arm 211 is defined between the two cutouts 212, and the elastic arm 211 is formed through the cutouts 212, and the forming method is simple.
