Technical Field
[0001] This invention relates to the field of automotive front bumper systems, specifically a front bumper assembly. Background Technology
[0002] The front bumper is a protective panel structure at the front of a car. A traditional front bumper assembly generally includes a front bumper plate, a grille, a spoiler, trim pieces, and mounting brackets.
[0003] Although existing automotive front bumper assemblies have achieved good performance, the following problems still exist:
[0004] 1. Due to its structure and size, traditional grille is usually screwed or clipped to the front bumper using brackets or feet. Traditional fixing methods are prone to loosening and lack assembly positioning, making it easy for the grille to shift during assembly, thus increasing assembly errors.
[0005] 2. Traditionally, the front bumper assembly is connected to the front of the car body through the front bumper plate, which means that the hood is essentially overlapping the front bumper plate. This inevitably increases the gap between the hood and the front bumper assembly. When the gap is large, too much airflow will enter the front compartment. Although this can increase the cooling effect of the front compartment, it will generate excessive wind resistance and increase fuel consumption.
[0006] 3. If the grille is made into an integral structure, the overall size of the mold will be larger during injection molding, which is not conducive to product demolding.
[0007] 4. Traditional grilles are single-layer panel structures with insufficient strength. Since grilles are exterior components, they are easily subjected to external forces. When the grilles themselves are not strong enough, they are easily damaged.
[0008] 5. When the traditional front bumper assembly is connected to the car body, it is mainly connected to adjacent parts by bonding or mounting brackets; however, the central area of the front bumper assembly lacks a connection with the car body, causing the central area of the front bumper to be in a suspended state; when subjected to external forces, the front bumper is prone to deformation; at the same time, due to the influence of gravity, the front bumper is prone to sag.

[0066] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.
[0067] The front bumper assembly disclosed in this invention mainly includes a front bumper body; the front bumper body includes a front bumper plate body 1, a grille 2, and decorative component mechanisms 6-8; the front bumper plate body 1 is provided with the grille 2; the front bumper plate body 1 and the grille 2 are connected by an overlapping method; the decorative component mechanisms 6-8 are connected to the front bumper plate body 1 and / or the grille 2; this invention discloses a front bumper assembly, mainly including three main components: the front bumper plate body 1, the grille 2, and the decorative component mechanisms 6-8. The front bumper plate body 1 is the main frame of the front bumper body, and the grille 2 is provided on the front bumper plate body 1. The grille 2 serves a ventilation effect, facilitating cooling of the front compartment of the car, while the decorative component mechanisms 6-8 mainly serve as airflow guides and decorations.
[0068] Specifically, the front bumper assembly disclosed in this invention mainly includes a front bumper body; the front bumper body is the main structure of a traditional front bumper assembly, while in this invention, the front bumper body includes a front bumper plate body 1, a grille 2, and decorative parts 6-8; the front bumper plate body 1 is provided with the grille 2; based on this design, the overlapping between the front bumper bodies is facilitated. At the same time, in this invention, the front bumper plate body 1 and the grille 2 are connected by an overlapping method; the overlapping method here ensures the stability of the connection between adjacent components and facilitates subsequent welding operations.
[0069] Meanwhile, in this invention, the decorative component mechanism 6-8 is connected to the front bumper body 1 and / or the central grille 2; the decorative component mechanism 6-8 forms different decorative components due to different design positions; mainly including grille decorative component 6, daytime running light decorative component 8 and end face decorative component 7; in this invention, each decorative component mainly plays the role of guiding airflow, reinforcement and aesthetics.
[0070] Meanwhile, for aesthetic purposes, the various decorative parts in this invention are required to be connected to the front bumper body 1 or the grille 2 by means of snap-fit.
[0071] Furthermore, the front bumper body 1 described in this invention is provided with a grille assembly groove 11; the grille assembly groove 11 on the front bumper body 1 is mainly to facilitate the assembly of the grille 2; the grille assembly groove 11 described in this invention includes a main assembly groove 111 and a lower assembly groove 112; at the same time, it is required that the lateral width of the lower assembly groove 112 is smaller than that of the main assembly groove 111. This setting ensures that the main grille 21 is also supported by the lower part of the front bumper body 1, avoiding the problem of easy shaking when the lower end of the main grille 21 is only connected to the lower grille 22.
[0072] Meanwhile, the main assembly groove 111 and the lower assembly groove 112 of the present invention are actually an integral groove structure, which is mainly used to realize the embedded connection of the central grille 2.
[0073] The central grille 2 includes a main grille 21 and a lower grille 22. In this invention, the central grille 2 is designed as two parts: the main grille 21 and the lower grille 22. This design is mainly to facilitate the injection molding production of the central grille 2, and also to facilitate subsequent welding operations with components such as the inner grille plate 9. In this invention, the main grille 21 and the lower grille 22 adopt a split design. Because the lower grille 22 does not require additional components, and decorative grille parts need to be installed at the edge of the upper grille, in actual design, the upper grille requires a connecting plate structure as mentioned below to be set around its perimeter. The lower grille does not need a connecting plate structure as mentioned below to be set around its perimeter.
[0074] In actual connection, the main grille 21 is embedded in the main assembly groove 111; the lower grille 22 is embedded in the lower assembly groove 112; in actual connection, the edge of the main grille 21 is snapped onto the adjacent component, and the edge of the lower grille 22 is snapped onto its adjacent component; snapping is prior art and will not be described in detail here.
[0075] To ensure the integrity of the grille 2, the main grille 21 is required to be connected to the lower grille 22 during actual installation. Specifically, the lower end of the main grille 21 is required to be connected to the upper end of the lower grille 22, mainly through a snap-fit connection. A grille decorative piece 6 is provided at the connection between the grille 2 and the lower grille 22. The grille decorative piece 6 is mainly arranged around the perimeter of the main grille 21. During subsequent connection, the grille decorative piece 6 acts as a cover over the connection between the main grille 21 and adjacent components, providing excellent coverage and shielding to prevent the connection from being exposed and affecting the aesthetics of the front bumper. At the same time, the grille decorative piece 6 also serves as a secondary reinforcement, greatly ensuring the stability of the connection between the main grille 21 and adjacent components.
[0076] Furthermore, in this invention, the main grille 21 includes a grille mesh body 211, and a connecting plate 212 is provided at the edge of the grille mesh body 211; the grille mesh body 211 is connected to adjacent components through the connecting plate 212; the connecting plate 212 provides a good bridging and connecting function, and multiple buckles or slots are provided on the connecting plate 212 to facilitate connection with the connected components during subsequent installation; also, in this invention, the grille mesh body 211 includes an annular rib frame 2011, and the annular rib frame 2011 is a single... The closed-loop structure is mainly a ring-shaped structure of a single plate, which serves as the main frame structure of the main grille 21. Simultaneously, a rib frame 201 and a license plate plate 202 are provided inside the ring-shaped rib frame 2011. The rib frame 201 provides internal support, while the license plate plate 202 facilitates license plate installation during subsequent use. In actual design, the license plate plate 202 is embedded in the rib frame 201. Specifically, the license plate plate 202 and the rib frame 201 are an integrated structure, which can be integrally injection molded during production.
[0077] In addition, the rib frame 201 described in this invention is also provided with a mounting through hole 2-1; a trailer hook cover plate 1101 is provided in the mounting through hole 2-1; the setting of the mounting through hole 2-1 facilitates the subsequent embedding and installation of the trailer hook cover plate 1101, and the setting of the trailer hook cover plate 1101 plays a good sealing role, which can cover and protect the trailer hook connection point on the vehicle body, increasing the difficulty for external debris to enter the trailer hook connection point.
[0078] Furthermore, the rib frame 201 described in this invention includes multiple longitudinal ribs 2012. These longitudinal ribs 2012 provide excellent longitudinal support, and are arranged in a parallel, spaced-apart pattern. This arrangement allows for easy perforation at the front end of the grille 2, facilitating air intake and enabling cooling of the front compartment. Additionally, diagonal ribs 2013 are provided between adjacent longitudinal ribs 2012 and between the longitudinal ribs 2012 and the annular rib frame 2011. These diagonal ribs 2013 provide excellent reinforcement, primarily to ensure proper alignment between adjacent longitudinal ribs 2012 or the outermost longitudinal rib 2012 and the annular rib frame 2011. The stability of the connection between the longitudinal ribs is ensured. Furthermore, this invention requires the formation of multiple ventilation slots 2014 between adjacent longitudinal ribs 2012 and between the longitudinal ribs 2012 and the inner wall of the annular rib frame 2011. The ventilation slots 2014 facilitate air intake operation in the front compartment of the vehicle. Simultaneously, to ensure the strength of the grille 2, each ventilation slot 2014 in this invention is provided with multiple oblique ribs 2013. Each oblique rib 2013 has its two ends connected to the adjacent longitudinal ribs 2012 or the inner wall of the annular rib frame 2011. Based on this design, the main grille 21 disclosed in this invention has a mesh structure, which, while ensuring ventilation, also greatly ensures the structural strength of the entire main grille 21.
[0079] In addition, in this invention, the oblique ribs 2013 in each ventilation slot 2014 are distributed at intervals; the outer surface of each oblique rib 2013 and longitudinal rib 2012 is an arc surface; the oblique ribs 2013 and longitudinal rib 2012 can reduce the wind resistance formed by the main grille 21 when the car is running by defining their respective outer surface structures, thereby reducing the wind resistance of the whole vehicle.
[0080] Furthermore, in this invention, each of the oblique ribs 2013 and longitudinal ribs 2012 is provided with an avoidance groove 20131; in this invention, the basic function of the avoidance groove 20131 is to reduce the strength of the main grid 21, and more importantly, it can cooperate with the insertion protrusion 916 on the inner plate of the grid 9 to achieve mutual snap-fit positioning when the inner plate of the grid 9 is connected to the main grid 21; ensuring the stability of the position when the main grid 21 and the inner plate of the grid are welded.
[0081] Furthermore, the central grid 2 in this invention also includes an inner grid plate 9; in this invention, the inner grid plate 9 serves as an internal support, mainly to ensure the structural strength of the main grid 21. At the same time, the inner grid plate 9 includes two symmetrically distributed individual inner plates 91; the two individual inner plates 91 are respectively arranged on both sides of the main grid 21; each individual inner plate 91 is connected to the grid mesh body 211 by welding; this connection method ensures the stability of the connection between the individual inner plate 91 and the grid mesh body 211.
[0082] Meanwhile, in this invention, each of the individual inner plates 91 is connected to the grid body 211 through multiple welding parts. Each welding part includes a welding groove 912 provided on the individual inner plate 91 and a welding plate 2015 provided on the grid body 211. The welding plate 2015 is inserted into the welding groove 912. Here, the welding plate 2015 plays two roles in actual use. One role is to play the role of insertion and positioning. The other role is to melt and adhere to the individual inner plate 91 through the action of the welding gun, thereby realizing the connection between the individual inner plate 91 and the grid body 211.
[0083] Furthermore, in this invention, the inner panel 91 of the single unit is provided with a plugging protrusion 916 on the side near the grid mesh 211; the plugging protrusion 916 is snapped into the relief groove 20131; the plugging protrusion 916 plays a good positioning role, and can also be used to increase the structural strength of the inner panel 91 itself; in other words, in this invention, the plugging protrusion 916 has two functions, one is to act as a reinforcing rib to increase the structural strength of the inner panel 91, and the other is to act as a snap-fit, which facilitates the snap-fit positioning between the inner panel 91 and the main grid 21.
[0084] Furthermore, in this invention, an assembly through hole 913 is provided on the inner plate 91 of the unit near the mounting through hole 2-1; the assembly through hole 913 is arranged opposite to the mounting through hole 2-1; the assembly through hole 913 mainly serves to avoid obstacles, facilitating the subsequent insertion of the trailer hook, and the setting of the assembly through hole 913 also facilitates the subsequent installation and positioning of the trailer hook cover plate 1101. In order to ensure the position limitation of the trailer hook cover plate 1101, a stepped platform 914 is provided at the edge of the assembly through hole 913 in this invention; the stepped platform 914 is arranged around the assembly through hole 913, which plays a good limiting role and is mainly used to cooperate with the trailer hook cover plate 1101.
[0085] Furthermore, in this invention, the connecting plate 212 includes a protruding plate 2122. The protruding plate 2122 provides excellent reinforcement and facilitates connection with the grille decoration 6. It provides internal support for the grille decoration 6, ensuring its stability. Additionally, the protruding plate 2122 is connected to the annular rib frame 2011 via a bridging plate 2123. The bridging plate 2123 facilitates the arrangement of the protruding plate 2122 and can be selected as needed during actual use. The protruding plate 2122 and the annular rib frame 2011 are spaced apart. Subsequent connections are mainly achieved through the bridging plate 2123. Furthermore, in this invention, the protruding plate 2122 includes a first plate 21221... The first plate 21221 and the second plate 21223 are spaced apart; the first plate 21221 is connected to the second plate 21223 by a connecting plate 21222; the first plate 21221 is connected to the annular rib frame 2011 by a bridging plate 2123; based on the above design, it can be seen that the protruding plate 2122 of the present invention is a structure with a vertical cross section of a triangle. Based on this setting, it is convenient to use with the grille decoration 6. At the same time, the protruding plate 2122 has a larger size on one side and a smaller size on the other, and has a good deformation capacity, which facilitates the actual assembly of the component. At the same time, when the grille decoration 6 is assembled later, the protruding plate 2122 can also press against the inner wall of the grille decoration 6 due to deformation, which plays a good supporting and limiting role.
[0086] Furthermore, the connecting plate in this invention also includes an outer plate 2121 connected to the protruding plate 2122; the outer plate 2121 is connected to the bridging plate 2123 through the protruding plate 2122; the outer plate 2121 is arranged intersecting with the grille mesh 211; in this invention, the outer plate 2121 subsequently acts as a connecting member, facilitating the connection between the main grille 21 and adjacent components. In actual connection, the length of the outer plate 2121 provided at the edge of the main grille 21 is selected as needed, its basic function being to achieve the connection between components; at the upper end of the main grille 21, that is, the end near the hood, the outer plate 2121 is required to be relatively long, and the outer plate 2121 is rubber-fitted with the grille mesh 211, that is, the outer plate 2121 is arranged at an angle. Based on this setting, during subsequent installation and use, the front bumper assembly can be attached to the front frame of the hood, better ensuring the stability of the front bumper assembly connection at the front of the car.
[0087] Furthermore, the front bumper body 1 described in this invention includes a lower base plate 101, a side panel 102, and a limiting plate 103. In this invention, the lower base plate 101 and the side panel 102 are the main structures of the front bumper body 1. In actual connection, the side panel 102 is connected to the lower base plate 101, and the end of the side panel 102 away from the lower base plate 101 is connected to the limiting plate 103. The limiting plate 103 is mainly used to provide a good limiting and calibrating function, so as to facilitate the cooperation between the front bumper body 1 and the external plate 2121 on the main grille 21.
[0088] Meanwhile, the limiting plate 103 is arranged intersecting with the side panel 102; the limiting plate 103 is arranged on the side of the side panel 102 away from the lower bottom plate 101; the limiting plate 103 extends from the side panel 102 to the lower bottom plate 101; this arrangement makes the limiting plate 103 arranged at the end of the side panel 102, and the limiting plate 103 at this time acts as a hook structure, which facilitates the connection between the front bumper body 1 and the main grille 21.
[0089] Furthermore, in this invention, the lower base plate 101 includes a bottom panel 1011, an upper clamping plate 1012, and an arc-shaped plate 1013; the bottom panel 1011 is connected to the upper clamping plate 1012 through the arc-shaped plate 1013; the upper clamping plate 1012 and the bottom panel 1011 are spaced apart; this arrangement also makes the lower base plate 101 form a plate structure with an opening on one side, which gives the lower base plate 101 itself a certain deformation capability, and can subsequently internally tension and bind the front guard beam 4 for fixation.
[0090] Meanwhile, in this invention, the side panel 102 is connected to the end of the upper plate 1012 away from the arc plate 1013; this arrangement causes the lower base plate 101 to protrude from the side panel 102. This arrangement can enhance the front bumper's shape and optimize its aesthetics. At the same time, the protruding lower base plate 101 can conveniently provide an installation position for the subsequent front bumper protection beam 4, facilitating the installation and assembly of the front bumper protection beam 4.
[0091] Furthermore, in this invention, the lower base plate 101 is provided with multiple guide plates 104. One function of the guide plates 104 is to facilitate the fitting of the front bumper beam 4 onto the lower base plate 101; another function is to provide inner wall support, ensuring the stability of the front bumper beam 4 fitting onto the lower base plate 101. Simultaneously, in this invention, the multiple guide plates 104 are spaced apart on the lower base plate 101. The multiple guide plates 104 are arranged sequentially and spaced apart along the length of the lower base plate 101, and are required to be distributed on both opposite sides of the lower base plate 101. Based on this arrangement, the lower base plate 101 can provide support for the front bumper beam 4 along its entire length. The protective beam 4 provides support and limits the movement of the components. Simultaneously, through the cooperation between these components, the guide plate 104 also acts as a reinforcing rib, ensuring the structural strength of the lower base plate 101. Furthermore, each guide plate 104 in this invention is provided with a guide groove 1041. The vertical cross-section of the guide plate 104 is trapezoidal. The guide groove 1041 provides excellent guidance and avoidance. In actual design, the guide groove 1041 is equivalent to a material reduction groove, mainly used to reduce the material at the end of the guide plate 104, thereby reducing the size of the end of the guide plate 104 and preventing the excessive size of the end of the guide plate 104 from affecting the normal assembly operation of the front protective beam 4.
[0092] Furthermore, in this invention, the front bumper body 1 is connected to a guide plate 3; the guide plate 3 plays a good guiding role, reducing the formation of vortices at the bottom of the front compartment; at the same time, it reduces the lift force on the vehicle, better ensuring the stability of the vehicle operation. Also, in this invention, the guide plate 3 includes a base plate 33; the base plate 33 is connected to an overlapping connecting plate 31 via a longitudinal connecting plate 32, and the longitudinal connecting plate 32 and the overlapping connecting plate 31 are arranged intersectingly; the overlapping connecting plate 31 overlaps on the lower base plate 101; the base plate 33 is an arc-shaped plate 1013; through the above design, this invention enables… The overall baffle plate 3 is a stepped plate structure. In subsequent use, the base plate 33 overlaps the edge of the lower base plate 101 of the front bumper body 1 through the overlapping connecting plate 31. This design facilitates the installation and positioning of the baffle plate 3. In actual installation, the overlapping connecting plate 31 is required to overlap the lower base plate 101, while the side of the longitudinal connecting plate 32 presses against the end of the lower base plate 101. Based on this design, when the baffle plate 3 disclosed in this invention is connected to the front bumper body 1, it is equivalent to using two surfaces to fit and limit the position, which greatly ensures the accuracy of the assembly position of the baffle plate 3.
