Description

Technical Field

[0001] This invention relates to the field of front bumper systems, specifically a method for assembling 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. The traditional front bumper assembly process is not standardized. Generally, the various components of the front bumper assembly are assembled at one workstation. At the same time, due to the disorder of the assembly order by the workers, it is easy to cause assembly interference between components. In addition, whether the traditional front bumper assembly is assembled on its own or on the whole vehicle, the assembly will cause the accumulation of errors, resulting in a large assembly gap between the front bumper assembly and adjacent components.

[0005] 2. Due to its structure and size, the traditional grille is usually screwed or clipped to the front bumper by brackets or feet. The traditional fixing method is prone to loosening and lacks assembly positioning, which can easily cause displacement during assembly and thus increase assembly errors.

[0006] 3. 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.

[0007] 4. If the mesh grid 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.

[0008] 5. The central grille is a single-layer panel structure, which is not strong enough. Since the central grille is an external component, it is easily subjected to external forces. When the central grille is not strong enough, it is easily damaged.

[0009] 6. 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 sagging.

[0010] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the design of the existing front bumper assembly. Summary of the Invention

[0011] The purpose of this invention is to provide a novel front bumper assembly method with high assembly efficiency.

[0012] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0028] Step 4: Connect the lower grille to the front bumper body and the main grille;

[0029] Step 5: Fit the grille trim onto the raised plates around the main grille;

[0030] Step 6: Connect the air deflector and mounting bracket mechanism to the front bumper body;

[0031] Step 7: Install a connector at each end of the front bumper body; then connect the front bumper guard beam to the front bumper body through the connectors.

[0032] Step 8: After completing Step 7, one front bumper assembly is installed. If you need to reassemble a new front bumper assembly, repeat Steps 1-7.

[0033] When the front bumper assembly is installed on the vehicle, the grille mounting bracket is required to overlap the front bumper of the vehicle; the front bumper assembly is connected to the front of the vehicle body via a connecting plate set at the edge of the grille.

[0034] In step 7, the connecting part is required to be connected to the front bumper body first. When installing the connecting part, the mounting plate is required to be connected to the front bumper body first by bolts. Then, the adhesive layer is installed on the mounting plate. Subsequently, the mounting plate is connected to the end of the front bumper protective beam by the adhesive layer.

[0035] In step 5, the snap-fit ​​component of the grille trim is required to pass through the main grille and connect to the front bumper body or lower grille around the main grille.

[0036] In step 2, the semi-finished grating parts and the semi-finished front bumper parts are required to be assembled at two separate workstations.

[0037] The width of the main assembly slot is greater than the width of the lower assembly slot.

[0040] Each individual inner panel is connected to the grid body by welding;

[0041] Each of the individual inner panels is connected to the grid body through multiple welding parts. Each welding part includes a welding slot provided on the individual inner panel and a welding plate provided on the grid body; the welding plate is inserted into the welding slot.

[0042] The front bumper body includes a lower base plate, a side panel, and a limiting plate; the limiting plate is arranged intersecting with the side panel; the limiting plate is arranged on the side panel away from the lower base plate; the limiting plate extends from the side panel to the lower base plate.

[0043] The lower base plate includes a bottom panel, an upper clamping plate, and an arc-shaped plate; the bottom panel is connected to the upper clamping plate through the arc-shaped plate; the upper clamping plate and the bottom panel are spaced apart; the side panel is connected to the end of the upper clamping plate away from the arc-shaped plate.

[0044] The front bumper body also includes a mounting bracket mechanism; the mounting bracket mechanism includes an end mounting bracket and a grille mounting bracket disposed at the end of the front bumper body; the grille mounting bracket includes an overlapping bracket disposed on the inner panel of the unit; the overlapping bracket is disposed perpendicular to the inner panel of the unit.

[0045] The advantages of this invention are:

[0046] This invention discloses an assembly method for a front bumper assembly. By limiting the assembly sequence of components, this invention can avoid assembly interference between components. Furthermore, by assembling corresponding semi-finished parts in stages before final integration, this invention can improve the assembly efficiency of the front bumper assembly to a certain extent. Additionally, the use of grille trim pieces can restrain the assembled main grille and lower grille, ensuring the stability of their position after overlap. Moreover, the design of the connecting parts allows the front bumper protective beam to have not only conventional snap-fit ​​connections but also end adhesive fixation, further ensuring the stability of the front bumper protective beam assembly.

[0079] 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.

[0080] A method for assembling a front bumper assembly, the front bumper assembly comprising: a front bumper body, a front bumper protective beam, and a deflector; the front bumper body comprising a front bumper body 1, a grille, a front bumper protective beam, and a decorative component mechanism; the front bumper body 1 is provided with a grille;

[0081] The front bumper body 1 is provided with a grille assembly groove 11; the grille assembly groove 11 includes a main assembly groove and a lower assembly groove;

[0082] The central grille includes a main grille 21 and a lower grille 22;

[0083] The main grille 21 is fitted into the main assembly slot;

[0084] The lower grille 22 is fitted into the lower mounting groove;

[0085] The main grille 21 is connected to the lower grille 22;

[0086] The decorative component mechanism includes a grille decorative component 6, a daytime running light decorative component 8, and an end face decorative component 7;

[0087] The assembly method includes the following steps:

[0088] Step 1: Select the various components of the front bumper assembly;

[0089] Step 2: Assemble the main grille 21 and the inner grille panel to form a semi-finished grille component; assemble the front bumper body 1, daytime running light trim 8, and end face trim 7 to form a semi-finished front bumper component;

[0090] Step 3: After completing Step 2, install the semi-finished grille into the grille assembly slot 11 on the front bumper body 1;

[0091] Step 4: Connect the lower grille 22 to the front bumper body 1 and the main grille 21;

[0092] Step 5: Fit the grille trim piece 6 onto the raised plate around the main grille 21;

[0095] Step 8: After completing Step 7, one front bumper assembly is installed. If you need to reassemble a new front bumper assembly, repeat Steps 1-7.

[0096] This invention discloses an assembly method for a front bumper assembly. By limiting the assembly sequence of components, this invention can avoid assembly interference between components. Furthermore, by assembling corresponding semi-finished parts in stages before final integration, this invention can improve the assembly efficiency of the front bumper assembly to a certain extent. Additionally, the use of grille trim 6 can restrain the assembled main grille 21 and lower grille 22, ensuring the stability of their position after overlap. Moreover, the connection part of this invention allows the front bumper protective beam to have not only conventional snap-fit ​​connections but also end adhesive fixation, further ensuring the stability of the front bumper protective beam assembly.

[0097] Furthermore, in step 2 of this invention, the semi-finished grille and the semi-finished front bumper are required to be assembled at two separate workstations; this arrangement allows for the assembly of different components in different areas, thereby improving the assembly efficiency of the front bumper assembly to a certain extent.

[0098] Furthermore, in this invention, the width of the main assembly slot is greater than the width of the lower assembly slot; based on this setting, a stepped platform is formed at the connection between the lower assembly slot and the main assembly slot, which facilitates the support and positioning of the main grille after subsequent assembly.

[0099] Furthermore, in this invention, the lower assembly groove is an inverted frustum-shaped groove; this design allows the sidewall of the lower assembly groove to provide upward support to the lower grille, thus better ensuring the support and positioning of the lower assembly groove for the lower grille.

[0100] Meanwhile, 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 plays a ventilation role, facilitating the cooling operation of the front compartment of the car, while the decorative component mechanisms 6-8 mainly play a guiding and decorative role.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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 order to avoid assembly difficulties and installation interference between adjacent components, the upper grille requires a connecting plate structure as mentioned below to be set around its perimeter. The lower grille does not need to have the connecting plate structure mentioned below.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.
