Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to the front structure of the vehicle body and the vehicle itself. Background Technology

[0002] The front bumper assembly is a crucial component of a vehicle's safety system. It typically consists of the bumper body and a trim panel. The front bumper assembly is visually prominent and is one of the parts that car buyers frequently examine. The trim panel is usually configured to closely match the curvature of the front of the vehicle, thus enhancing the overall aesthetics of the front. Furthermore, the trim panel provides effective protection for easily scratched areas of the vehicle and can be replaced separately after a collision.

[0003] When a vehicle collides with a pedestrian, the front bumper trim panel needs to collapse to absorb the collision energy in order to protect the pedestrian's legs. However, the current installation structure of the trim panel does not have a dedicated collapse energy-absorbing structure. The collapse space of the trim panel is limited, requiring large-area partial dent of the body sheet metal or the entire plastic hood under the front bumper trim panel to collapse to absorb the collision energy. It is difficult to achieve the expected energy absorption. Utility Model Content

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0071] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0072] This application provides a front structure for a vehicle body. In one embodiment, reference is made to... Figures 1 to 6 , Figure 1This is a three-dimensional structural diagram of an embodiment of the vehicle front structure provided in this application. Figure 2 yes Figure 1 An exploded structural diagram of the front part of the vehicle body. Figure 3 yes Figure 1 Side view of the front structure of the vehicle body. Figure 4 yes Figure 1 A top view of the front structure of the vehicle body. Figure 5 yes Figure 4 A three-dimensional sectional view of the front structure of the vehicle body along section AA. Figure 6 yes Figure 4 A cross-sectional view of section AA in the front structure of the vehicle body. This front structure includes a front bumper body 100, a front bumper trim panel 200, a body assembly 400, and a mounting bracket 500. The front bumper trim panel 200 is separately mounted from the front bumper body 100. (See also...) Figure 7 , Figure 7 yes Figure 1 The diagram shows the three-dimensional structure of the front body structure after removing the front bumper trim panel 200. The body assembly 400 is used to connect to the front cover 300 of the body. The body assembly 400 is located on one side of the front bumper body 100 and the front bumper trim panel 200 in the length direction X of the body. The body assembly 400 is provided with a first recessed platform 411 facing the front bumper trim panel 200. The mounting bracket 500 is housed in the first recessed platform 411 and connects the first recessed platform 411 with the front bumper trim panel 200 to maintain the relative position of the front bumper trim panel 200 and the front bumper body 100.

[0073] The front bumper body 100 and the front bumper trim panel 200 together constitute the front bumper assembly of the vehicle body. The front bumper refers to the front bumper. The main function of the front bumper body 100 is to absorb and disperse the impact force of a collision to protect the vehicle body and the safety of the occupants, while also taking into account pedestrian protection and the aesthetic design of the vehicle. The front bumper trim panel 200 is used for decoration. Its shape can match the curvature of the front of the vehicle body to enhance the appearance of the front of the vehicle body.

[0074] The front structure of the vehicle body in this application embodiment typically also includes a front cover 300. The front cover 300 is a key component of the front of the vehicle body. The core components of the vehicle are usually located under the front cover 300. For example, when the vehicle is a fuel vehicle, the engine, electrical circuit, oil circuit, radiator and various conduction systems are located under the front cover 300. When the vehicle is a new energy vehicle, the core components such as the motor, electronic control system and cooling system are located under the front cover 300. Therefore, the front cover 300 can usually be opened, that is, the front cover 300 can be opened or closed relative to the front bumper body 100 to facilitate the maintenance and replacement of the various core vehicle components under the front cover 300.

[0075] The front bumper body 100 and the front bumper trim panel 200 are separately configured so that the front bumper trim panel 200 can move together with the front cover 300 during the opening or closing of the front cover 300, while the front bumper body 100 remains stationary.

[0076] The relative positions of the front bumper body 100 and the front bumper trim panel 200 can be varied. For example, the front bumper body 100 can completely surround the front bumper trim panel 200, or it can only partially surround the front bumper trim panel 200. The front bumper body 100 and the front bumper trim panel 200 can also be arranged in a non-surrounding configuration. In a specific embodiment, the front bumper body 100 has a front bumper top 100A and a front bumper bottom 100B that are opposite each other along the height direction Z of the vehicle body. The front bumper top 100A is provided with a mounting opening 110, and the front bumper trim panel 200 is embedded in the mounting opening 110. Thus, during the opening or closing of the hood 300, the front bumper trim panel 200 can be separated from the front bumper body 100 through the mounting opening 110 or embedded within the mounting opening 110.

[0077] The body assembly 400 serves as an intermediate connector to connect and fix the front bumper trim panel 200 to the front cover 300. The body assembly 400 can also be used to install other components such as the through light, so that the front bumper trim panel 200 and other components such as the through light can move together with the front cover 300 during opening or closing. The body assembly 400 can be made of plastic or metal.

[0078] The body assembly 400 is typically located on one side of the front bumper body 100 and the front bumper trim panel 200 in the length direction X of the vehicle body, specifically behind the front bumper body 100 and the front bumper trim panel 200 in the length direction X of the vehicle body, so that the body assembly 400 is hidden within the front structure of the vehicle body and is not exposed.

[0079] The mounting bracket 500 serves as an intermediate connector between the front bumper trim panel 200 and the body assembly 400. The mounting bracket 500 and the front bumper trim panel 200, as well as the mounting bracket 500 and the body assembly 400, can be connected and fixed by methods including, but not limited to, welding and snap-fitting. The mounting bracket 500 can be made of, but not limited to, aluminum alloy. The front bumper trim panel 200 is connected to the body assembly 400 via the mounting bracket 500, and further connected to the front cover 300, thus maintaining the relative position of the front bumper trim panel 200 and the front bumper body 100. The front bumper trim panel 200 and the front bumper body 100 are not directly connected. When the front cover 300 is closed, the front bumper trim panel 200 is embedded in the mounting opening 110 of the front bumper body 100, so that the front bumper trim panel 200 and the front bumper body 100 together constitute the exterior structural components of the front of the vehicle body.

[0080] A first recessed platform 411 is provided on the body assembly 400 facing the front bumper trim panel 200 for installing and accommodating the mounting bracket 500, thereby providing sufficient collapsible space for the mounting bracket 500. The first recessed platform 411 may be a recessed groove-like structure.

[0081] The front structure of the vehicle body provided in the embodiments of this application includes a front bumper body 100, a front bumper decorative panel 200, a body assembly 400, and a mounting bracket 500. The front bumper decorative panel 200 is separately disposed from the front bumper body 100. The front bumper decorative panel 200 is mounted to the body assembly 400 via the mounting bracket 500, and then connected to the front cover 300 of the vehicle body via the body assembly 400, so that it can be opened or closed together with the front cover 300. The body assembly 400 has a first recessed platform 411 on the side facing the front bumper decorative panel 200. The mounting bracket 500 is housed in the first recessed platform 411. The first recessed platform 411 can provide sufficient crumple space for the mounting bracket 500. When a pedestrian hits the front bumper decorative panel 200, the impact force is transmitted from the front bumper decorative panel 200 to the mounting bracket 500. The collision energy is absorbed through the crumple of the mounting bracket 500, effectively reducing the risk of injury to the pedestrian's legs, thereby improving the pedestrian leg protection score.

[0082] Please see Figures 8 to 11 , Figure 8 yes Figure 2 An exploded three-dimensional diagram of the front structure of the vehicle body, showing the box assembly and mounting bracket. Figure 9 yes Figure 2 A three-dimensional schematic diagram of the assembly structure of the box assembly and mounting bracket in the front structure of the vehicle body. Figure 10 yes Figure 8 and Figure 9 A three-dimensional structural diagram of the mounting bracket. Figure 11 yes Figure 10 A top view of the mounting bracket is shown in some embodiments. The mounting bracket 500 includes a first leg 510, a connecting plate portion 530, and a second leg 520 arranged at an angle. The first leg 510 and the second leg 520 are located on opposite sides of the connecting plate portion 530. The ends of the first leg 510 and the second leg 520 away from the connecting plate portion 530 are respectively connected to a first recessed platform 411. The connecting plate portion 530 is connected to the front bumper trim panel 200.

[0083] The mounting bracket 500 can be formed by, but is not limited to, stamping. The first leg 510 and the second leg 520 can extend along the length X of the vehicle body. The first leg 510 and the second leg 520 provide a crumple zone for energy absorption. The crumple zone of the mounting bracket 500 is achieved by the deformation of the first leg 510 and the second leg 520 under the impact force. The connecting plate portion 530 serves as a fixing component for the front bumper trim panel 200. The first leg 510 and the connecting plate portion 530 are set at an angle, and the second leg 520 and the connecting plate portion 530 are also set at an angle. For example, the angle range between the first leg 510 and the connecting plate portion 530, and between the second leg 520, is between 80 degrees and 120 degrees. The specific angle is adjusted according to the impact energy absorption requirements. The first recess 411 provides a fixed position for the ends of the first leg 510 and the second leg 520, and at the same time provides crumple movement space for the first leg 510 and the second leg 520 during a collision.

[0084] The end of the first leg 510 can be bent to form a first flange 512. The first flange 512 can be attached and fixed to the inner wall of the first sinking platform 411 by welding, snap-fitting or screwing. The first leg 510 is connected and fixed to the first sinking platform 411 through the first flange 512.

[0085] The end of the second leg 520 can be bent to form a second flange 522. The second flange 522 can be attached and fixed to the inner wall of the first sinking platform 411 by welding, snap-fitting or screwing. The second leg 520 is connected and fixed to the first sinking platform 411 through the second flange 522.

[0086] The mounting bracket 500 in this embodiment is composed of a first leg 510, a connecting plate portion 530, and a second leg 520 forming a "U"-shaped structure. The angled arrangement formed by the two legs (the first leg 510 and the second leg 520) and the connecting plate portion 530 can improve the overall structural stability of the mounting bracket 500, allowing the front bumper trim panel 200 to be stably supported within the first recessed platform 411. On the other hand, it can reserve space for the first leg 510 and the second leg 520 to collapse, thereby guiding the stress distribution during a collision and allowing the mounting bracket 500 to collapse along the first leg 510 and the second leg 520 to absorb energy.

[0087] In some embodiments, the first leg 510 is provided with a first weakening hole 511, and the second leg 520 is provided with a second weakening hole 521; along the length direction X of the vehicle body, the size of the first leg 510 is larger than the size of the second leg 520, and the size of the first weakening hole 511 is larger than the size of the second weakening hole 521.

[0088] The first weakening hole 511 and the second weakening hole 521 can be formed by punching. The first weakening hole 511 and the second weakening hole 521 are used to weaken the strength of the first leg 510 and the second leg 520, respectively, which is conducive to the crushing deformation of the first leg 510 and the second leg 520 under the impact energy. The first leg 510 is longer than the second leg 520, which is conducive to making the size of the first weakening hole 511 on the first leg 510 larger than the size of the second weakening hole 521 on the second leg 520. This makes the strength of the first leg 510 lower than that of the second leg 520, and the first leg 510 is easier to crush. Therefore, when there is a collision, the mounting bracket 500 is more likely to collapse towards the first leg 510, which can guide the direction of the collapse of the mounting bracket 500, thereby controlling the directional collapse of the mounting bracket 500.

[0089] In this embodiment, by differentiating the lengths of the first leg 510 and the second leg 520, and by providing weakening holes of different sizes on the first leg 510 and the second leg 520 respectively, the collapse guide function of the mounting bracket 500 can be achieved, thereby controlling the directional collapse of the mounting bracket 500.

[0090] In some embodiments, the first leg 510 and the second leg 520 are both plate-like structures, and at least one of the first leg 510 and the second leg 520 extends in a stepped manner along the length direction X of the vehicle body.

[0091] Specifically, the first support leg 510 includes a first support leg outer plate portion 510A, a first support leg transition portion 510B, and a first support leg inner plate portion 510C, arranged sequentially along the length direction X of the vehicle body. The first support leg outer plate portion 510A and the first support leg inner plate portion 510C are spaced apart along both the length direction X and the width direction Y of the vehicle body. The first support leg outer plate portion 510A is closer to the connecting plate portion 530 than the first support leg inner plate portion 510C, and the first support leg outer plate portion 510A is closer to the second support leg 520 than the first support leg inner plate portion 510C. The first support leg outer plate portion 510A and the first support leg inner plate portion 510C are connected by the first support leg transition portion 510B. Thus, when a pedestrian impacts the front of the vehicle body, the first support leg 510 can collapse at the first support leg transition portion 510B.

[0092] The second support leg 520 includes a second support leg outer panel 520A, a second support leg transition portion 520B, and a second support leg inner panel 520C, arranged sequentially along the length direction X of the vehicle body. The second support leg outer panel 520A and the second support leg inner panel 520C are spaced apart along both the length direction X and the width direction Y of the vehicle body. The second support leg outer panel 520A is closer to the connecting plate portion 530 than the second support leg inner panel 520C, and the second support leg outer panel 520A is closer to the first support leg 510 than the second support leg inner panel 520C. The second support leg outer panel 520A and the second support leg inner panel 520C are connected by the second support leg transition portion 520B. Thus, when a pedestrian impacts the front of the vehicle body, the second support leg 520 can crumple at the second support leg transition portion 520B.

[0093] In this embodiment, the stepped structure of the first leg 510 and the second leg 520 facilitates control over the crushing position of the first leg 510 and the second leg 520, thereby making it easier to control the crushing depth of the first leg 510 and the second leg 520. In other embodiments, it is not excluded that the first leg 510 and the second leg 520 may have a flat plate structure.

[0094] In some embodiments, along the direction from the side of the connecting plate portion 530 toward the front bumper trim panel 200 to the side of the connecting plate portion 530 away from the front bumper trim panel 200, the distance between the first leg 510 and the second leg 520 gradually increases, and the first leg 510 and the second leg 520 are arranged along the width direction Y of the vehicle body.

[0095] In this embodiment, the gradual design of the distance between the first support leg 510 and the second support leg 520 along the length direction X of the vehicle body can form a stable triangular support structure, improve the structural stability of the mounting bracket 500, thereby improving the installation reliability of the front bumper trim panel 200. At the same time, it can also provide guidance for the collapse of the first support leg 510 and the second support leg 520, so that the first support leg 510 and the second support leg 520 collapse in a direction that brings them closer to each other.

[0096] In some embodiments, the first recessed platform 411 has a first recessed platform portion 4111 and a second recessed platform portion 4112 arranged at an angle. The first recessed platform portion 4111 is opposite to and spaced apart from the front bumper trim panel 200 in the length direction X of the vehicle body. The first recessed platform portion 4111 includes a protruding region 4111A and a recessed region 4111B arranged in the width direction Y of the vehicle body. The recessed region 4111B is recessed relative to the protruding region 4111A in a direction away from the front bumper trim panel 200. A first support leg 510 is connected to the recessed region 4111B, and a second support leg 520 is connected to the protruding region 4111A.

[0097] For example, the first recessed plate portion 4111 can be parallel to the height direction Z of the vehicle body, and the included angle between the first recessed plate portion 4111 and the second recessed plate portion 4112 can be a right angle or an obtuse angle, preferably an obtuse angle, such as 100 degrees, 110 degrees or 120 degrees, to further expand the collapsible space of the mounting bracket 500.

[0098] In this embodiment, the front bumper trim panel 200 is fixedly installed on the first recessed platform plate 4111 of the first recessed platform 411, which is beneficial for the collision force along the length direction X of the vehicle body to be transmitted to the body assembly 400 via the mounting bracket 500. The recessed area 4111B of the first recessed platform plate 4111 corresponds to the first leg 510 of the mounting bracket 500, and the protruding area 4111A of the first recessed platform plate 4111 corresponds to the second leg 520 of the mounting bracket 500. The recessed area 4111B expands the collapse space of the longer first leg 510, so that the mounting bracket 500 can deform and collapse in an orderly manner in a preset direction when under pressure.

[0099] In some embodiments, at least two mounting brackets 500 are arranged at intervals along the width direction Y of the vehicle body. For example, two, three, four, or more mounting brackets 500 are arranged at intervals along the width direction Y of the vehicle body within the first recess 411. Figure 7 and Figure 9 This shows the case where two mounting brackets 500 are installed inside the first sinking platform 411.

[0100] In this embodiment, by arranging multiple mounting brackets 500 at intervals along the width direction Y of the vehicle body, the multiple mounting brackets 500 have a better collapse energy absorption effect and also enhance the connection stability between the front bumper trim panel 200 and the body assembly 400, avoiding the risk of structural instability caused by single-point failure, thereby comprehensively improving the vehicle's pedestrian protection performance.

[0101] In some embodiments, the body assembly 400 includes an outer body panel 410 and an inner body panel 420. The inner body panel 420 is located on the side of the outer body panel 410 facing away from the front bumper trim panel 200 in the longitudinal direction X of the vehicle body. The outer body panel 410 and the inner body panel 420 together define the inner cavity 400A of the body. A first recessed platform 411 is formed on the outer body panel 410. The periphery 413 of the outer body panel 410 is attached and fixed to the front bumper trim panel 200.

[0102] The body assembly 400 includes an outer body panel 410 and an inner body panel 420. The inner body panel 420 is located on the side of the outer body panel 410 facing away from the front bumper trim panel 200. Together, they form an inner cavity 400A. The outer body panel 410 and the inner body panel 420 can be connected and fixed by welding, snap-fitting, or screwing. Thus, the inner cavity 400A enhances the overall rigidity of the body assembly 400 and also absorbs collision energy. For example, the body assembly 400 may further include body end plates 430 and body top plates 440. There are two body end plates 430, which are located at the two ends of the body outer plate 410 and body inner plate 420 along the width direction Y of the vehicle body, respectively. The body top plate 440 is located on the side of the body outer plate 410 and body inner plate 420 along the height direction Z of the vehicle body facing the front cover 300. The body top plate 440 is used to connect to the front cover 300 of the vehicle body. The body cavity 400A may be defined by the body outer plate 410, body inner plate 420, body end plates 430 and body top plate 440.

[0103] The outer panel 410 is a component used to form the first recessed platform 411. In order to improve the connection stability between the front bumper trim panel 200 and the body assembly 400, the periphery 413 of the outer panel 410 can be spot-welded to the front bumper trim panel 200. The periphery 413 of the outer panel 410 refers to the area surrounding the first recessed platform 411. Thus, the front bumper trim panel 200 is fixed to the periphery 413 of the outer panel 410, which is mainly used to fix the front bumper trim panel 200 to the outer panel 410. The mounting bracket 500 in the first recessed platform 411 of the outer panel 410 is connected to the front bumper trim panel 200, which is mainly used to absorb collision energy through the collapse of the mounting bracket 500.

[0104] In some embodiments, see again Figures 1 to 7 The front structure of the vehicle body also includes a front cover 300 and a through light 600; the front cover 300 is spaced apart from the front bumper body 100 and the front bumper trim panel 200 in the height direction Z of the vehicle body, and is located on the side of the front bumper top 100A away from the front bumper bottom 100B, and the front cover 300 is fixedly supported on the body assembly 400; the through light 600 is located between the front cover 300 and the front bumper trim panel 200 in the height direction Z of the vehicle body, and covers the gap between the front cover 300 and the front bumper trim panel 200; wherein, the body assembly 400 is also provided with a second recessed platform 412, the second recessed platform 412 is located on the side of the first recessed platform 411 in the height direction Z of the vehicle body, and the through light 600 is connected to the front cover 300 and housed in the second recessed platform 412.

[0105] The through light 600 is embedded between the front cover 300 and the front bumper trim panel 200 and fixed to the body assembly 400 so that it can open and close together with the front cover 300. The through light 600 can use LED light source and can extend along the width direction Y of the vehicle body. Its outline can match the curvature of the front of the vehicle body, thereby stretching the visual width of the front of the vehicle body, making the vehicle highly recognizable when driving at night, enhancing driving safety, and also improving the overall sense of style and grandeur of the vehicle.

[0106] The second recessed platform 412 is used to install and accommodate the through light 600. Specifically, the second recessed platform 412 has a third recessed platform plate portion 4121 and a fourth recessed platform plate portion 4122 arranged at an angle. The third recessed platform plate portion 4121 extends along the height direction Z and the width direction Y of the vehicle body. The third recessed platform plate portion 4121 and the first recessed platform plate portion 4111 are spaced apart in the length direction X of the vehicle body and are located on the side of the first recessed platform plate portion 4111 away from the front bumper trim panel 200. The fourth recessed platform plate portion 4122 connects the first recessed platform plate portion 4111 and the third recessed platform plate portion 4121. The through light 600 is installed on the third recessed platform plate portion 4121. Specifically, the third recessed platform plate portion 4121 is provided with a lamp mounting hole 41210. The through light 600 is bolted through and fastened to the lamp mounting hole 41210 to achieve fixed installation of the through light 600 on the third recessed platform plate portion 4121.

[0107] The second recessed platform 412 can be formed by stamping the outer panel 410 of the box body. The outer panel 410 can be an integral structure or a split structure. For example, the outer panel 410 of the box body is formed by welding two independent stamping plates. The first recessed platform 411 and the second recessed platform 412 are respectively set on the two stamping plates so that the first recessed platform 411 and the second recessed platform 412 can be formed better.
