Description

Technical Field

[0001] This invention relates to the field of vehicle front bumper technology, specifically to a contrasting color front bumper structure, a front bumper assembly having the contrasting color front bumper structure, and an assembly method thereof. Background Technology

[0002] The front bumper of a car is the core visual area of ​​the entire vehicle's appearance, and it is also a key component that determines wind resistance, NVH (noise, vibration, and harshness), and the economics of repairing low-speed collisions.

[0003] With the continuous upgrading of personalized consumption trends and the increasing demand for mixed-line production from OEMs, the traditional integrated front bumper structure has gradually exposed the following prominent problems:

[0004] 1. Limited color options and lack of personalization

[0005] The current front bumper generally adopts the "integrated injection molding + integrated spraying" solution, and one mold can only present one color.

[0006] If a two- or three-color version is to be launched, additional color-blocking tooling or post-production film / painting is required, which leads to a longer production cycle, increased costs, and difficulty in meeting the personalized demands of "different colors for the same vehicle" or "color changes for the same part".

[0007] 2. It is not conducive to mixed-line production and rapid color change after sales:

[0008] Since the individual components are only finally fastened on the assembly line, the painting must be completed before the assembly, making it impossible to achieve flexible color matching at the "part level". If the aftermarket wants to change the color of a part, it can only be repainted, which is inefficient and puts a lot of pressure on the environment.

[0009] 3. The connection between the front bumper body and the grille is troublesome;

[0010] Traditionally, the front bumper body and the grille are directly connected, and there is often a large assembly gap at the connection point.

[0011] In addition, some grille edges generally require the addition of chrome-plated bright strips. Traditionally, chrome-plated bright strips are usually placed around the perimeter of the grille. However, since the grille itself is generally an irregular structure, it is difficult to produce the chrome-plated bright strips and the grille as a single unit.

[0012] Existing patent CN 223327448 U discloses a spliced ​​front bumper assembly; however, it does not explicitly disclose the technical content that solves the above-mentioned technical problems.

[0066] 1. Front bumper body, 2. Lower grille, 3. Side panel of the grille, 4. Lower air deflector, 5. Mounting bracket. Detailed Implementation

[0067] 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.

[0068] A two-tone front bumper structure includes a front bumper body 1, a lower grille 2, a central grille side panel structure, and a lower air deflector 4. The main structure of the front bumper is formed by the coordinated use of the front bumper body 1, the lower grille 2, the central grille side panel structure, and the lower air deflector 4. The front bumper structure of the present invention adopts a split modular design, which facilitates the production and installation of the front bumper structure.

[0069] In this invention, the front bumper body 1 is provided with a lower assembly groove 103 and a grille assembly groove 11 for installing the grille; the grille side panel structure is arranged in the grille assembly groove 11; the lower grille 2 is arranged in the lower assembly groove 103; the present invention, through the setting of the lower assembly groove 103 and the grille assembly groove 11, facilitates the assembly and positioning of the lower grille 2 and the grille side panel structure, and at the same time can also realize the embedding and installation of the lower grille 2 on the front bumper body 1, ensuring the flatness of the outer side of the front bumper structure.

[0070] The grille mounting slot 11 serves as an installation positioning feature, facilitating the installation and limiting of the central grille. In this invention, the grille mounting slot 11 is located in the central area of ​​the front bumper body 1. The grille mounting slot 11 extends through the front bumper body 1 along the X direction of the vehicle and is a recessed groove structure along the Z direction of the vehicle. During subsequent grille assembly, the grille is essentially inserted into the front bumper body 1, providing excellent installation and limiting.

[0071] In this invention, the lower guide plate 4 is arranged on the side of the front bumper body 1 away from the grille assembly groove 11; the lower guide plate 4 plays a good role in guiding the flow.

[0072] In this invention, the front bumper body 1, lower grille 2, middle grille side panel structure, and lower guide plate 4 are all coated with paint. The paint coatings on the front bumper body 1, lower grille 2, middle grille side panel structure, and lower guide plate 4 are either the same color or different color. This invention requires that the paint coatings on the front bumper body 1, lower grille 2, middle grille side panel structure, and lower guide plate 4 be either the same color or different color. Generally, it is required that the paint coatings on adjacent front bumper bodies 1, lower grille 2, middle grille side panel structure, and lower guide plate 4 be different color. This arrangement achieves a contrasting color design, increases the color variety of the outer surface of the front bumper structure, and increases the recognizability and distinctiveness of the front bumper structure.

[0073] The front bumper body 1 of this invention provides a "reference coordinate"; the front bumper body 1, the lower grille 2, the middle grille side plate 3, and the lower guide plate 4 are four major "color block units".

[0074] The adjacent unit components can be quickly installed by snap-fit, screw-fit, and adhesive bonding. The front bumper body 1, lower grille 2, middle grille side plate 3, and lower guide plate 4 of this invention can be independently painted or combined in different colors. This satisfies the mixed production line requirements of OEMs and allows users / after-sales service to achieve "single-part color change" personalization, while also taking into account wind resistance, NVH, and low-speed maintenance economy.

[0075] In this invention, the front bumper body 1, lower grille 2, center grille side panel 3, and lower air deflector 4 are all essentially exterior trim parts. In this invention, they are all independently painted and independently assembled "color block units". Different colors can be used in the same vehicle, and the same parts can be color-changed.

[0076] All units use a "hidden card-hang-insert" three-in-one interface, eliminating exposed bolts and ensuring clean color boundaries and no color difference from screw caps.

[0077] In this invention, the grille side panel structure includes two symmetrically spaced grille side panels 3 distributed on the front bumper body 1; the grille side panels 3 are snapped onto the front bumper body 1; a first insert plate is provided at the edge of the grille side panel 3; the grille side panel 3 of this invention is mainly a plate structure, mainly arranged at the inner edge of the grille assembly groove 11; it is subsequently arranged on the front bumper assembly in conjunction with the grille and headlight assembly.

[0078] In this invention, the grille side panel 3 is snapped onto the front bumper body 1; generally, the grille side panel 3 is connected to the front bumper body 1 by multiple snap-fit ​​mechanisms, specifically connected to the support overlap flange 101 on the front bumper body 1.

[0079] In addition, a first insert plate 303 is provided at the edge of the side panel 3 of the grille in this invention; the first insert plate 303 is set perpendicular to the side panel 3 of the grille in this invention; in subsequent use, the side panel 3 of the grille is inserted into the slot on the grille through the first insert plate 303; based on the cooperative use of multiple first insert plates 303 and multiple slots, multi-point insertion limit between the side panel 3 of the grille and the grille is realized, ensuring the connection and installation between the grille and the side panel 3 of the grille.

[0080] In addition, the supporting overlapping flange 101 is also provided with a second insert plate 102 in this invention. In subsequent use, the supporting overlapping flange 101 can be inserted into the grille through the second insert plate 102, thereby realizing the relative insertion limit between the front bumper body 1 and the grille.

[0081] Furthermore, in this invention, the side panel 3 of the grille includes a side panel body 31. The side panel body 31 has a side panel flange 32 on the side away from the front bumper body 1. The side panel flange 32 and the side panel body 31 are arranged perpendicular to each other. The vertical cross-section of the side panel flange 32 and the side panel body 31 is L-shaped. Based on this setting, the edge of the side panel 3 of the grille has an L-shaped structure, making the side panel 3 of the grille form a hook-like structure, which is convenient to hang on the side of the supporting overlapping flange 101 of the front bumper body 1 during subsequent use. In addition, in this invention, the side flange is in surface contact with the side of the grille. Based on this design, the side flange 32 and the side of the grille are in surface contact, which ensures the contact area between the side panel 3 of the grille and the grille, thereby playing a role in mutual calibration and positioning.

[0082] Furthermore, in this invention, the side panel body 31 includes a side panel base, on which an insertion protrusion is provided. The side panel base is inserted into the insertion groove 1012 on the front bumper body 1 through the insertion protrusion. The side panel base is the main structure of the side panel body 31, and the insertion protrusion on the side panel base cooperates with the insertion groove 1012 on the front bumper body 1. This provides a good mutual insertion and positioning function, ensuring the installation and positioning of the grille side panel 3 on the grille, and ensuring the accuracy of the installation position of the grille side panel 3 on the grille.

[0083] Furthermore, in this invention, the side panel base includes a first side panel 311 and a second side panel 312; the first side panel 311 and the second side panel 312 are intersecting; a hook-up corner 313 is provided at the corner of the first side panel 311 and the second side panel 312; a front bumper mounting groove 301 is formed on the side of the first side panel 311 and the second side panel 312 near the front bumper body 1; the hook-up corner 313 and the side of the first side panel 311 near the grille form a grille mounting groove 302; based on this design... The design of the grille mounting groove 302 facilitates the mounting and positioning of the side panel base on the grille, better ensuring the accuracy and stability of the installation position of the grille and the grille side panel 3. In this invention, the front bumper mounting groove 301 allows the lower edges of the first side panel 311 and the second side panel 312 to press against and adhere to the upper side of the front bumper body 1. Based on the above design, both sides of the grille side panel 3 have an inverted L-shaped structure, which facilitates the mounting and installation of the grille side panel 3 on the front bumper body 1 and the grille.

[0084] In this invention, the first side plate 311, the second side plate 312, and the hook corner 313 are an integral structure; based on this design, the injection molding production of the grille side plate 3 is facilitated.

[0085] In this invention, the lower grille 2 is embedded in the lower mounting groove 103 of the front bumper body 1, which ensures the accuracy of the installation position of the lower grille 2 on the front bumper body 1.

[0086] In this invention, the lower assembly groove 103 includes a main sink groove 1031 and a plurality of assembly through grooves 1032; the assembly through grooves 1032 are connected to the main sink groove 1031; the depth of the main sink groove 1031 is less than the thickness of the front bumper body 1; the assembly through grooves 1032 are disposed in the main sink groove 1031; the main sink groove 1031 is disposed on the end face of the front side of the front bumper body 1, and the subsequent lower grille 2 is equivalent to being inserted into the main sink groove 1031, so as to avoid the lower grille 2 protruding from the front bumper body 1 as much as possible.

[0087] The assembly slot 1032 is a through slot, which facilitates the passage of air through the front and rear of the front guard structure, making it easier for airflow to pass through the front guard structure.

[0088] In addition, in this invention, the mounting slot 1032 can be used for the insertion of local structures in the lower grille 2; thereby limiting the installation of the lower grille 2 and preventing the lower grille 2 from moving around on the front bumper body 1.

[0089] In this invention, the lower grille 2 is also connected to the front bumper body 1 by snap fasteners, and the specific number of snap fasteners can be selected as needed.

[0090] In this invention, the mounting slot 1032 is essentially a through slot; the structural arrangement that requires ventilation in the front bumper structure is also set in the area of ​​the front bumper structure where additional components need to be installed; such as radar mounting position, daytime running light mounting position, etc.

[0091] In this invention, the lower grille 2 includes a bottom grille 22 and a fog light grille 21. The bottom grille 22 and the fog light grille 21 are designed separately, which facilitates the production and subsequent installation of the lower grille 2. In this invention, the bottom grille 22 is a long strip structure, and a fog light grille 21 is provided at each end of the bottom grille 22.

[0092] In this invention, the bottom grille 22 includes a grille base plate 201 and a license plate 202. The grille base plate 201 is the main structure of the bottom grille 22, while the license plate is mainly used for subsequent installation of the vehicle license plate. The grille base plate 201 and the license plate 202 have an integrated structure. After the license plate 202 is arranged at the center of the grille base plate 201, the license plate 202 is provided with a mounting groove 2021. The license plate 202 is mounted on the front bumper body 1 through the mounting groove 2021. The mounting groove 2021 makes the license plate 202 also act as a mounting component, which better ensures the accuracy of the installation position of the bottom grille 22 on the front bumper body 1.

[0093] In this invention, the grille base plate 201 is embedded in the main body groove 1031, and the license plate 202 is protruding on the grille base plate 201. Therefore, during subsequent installation, the license plate 202 is also arranged protruding from the front bumper body 1. Based on this design, it is convenient to hang and install the bottom grille 22 on the front bumper body 1.

[0094] Furthermore, in this invention, a bottom grid 203 is provided on the grid base plate 201; the bottom grid 203 protrudes from the grid base plate 201; the bottom grid 22 is inserted into the corresponding mounting slot 1032 through the bottom grid 203; in this invention, the grid base is the main structure of the bottom grid 22; the bottom grid 203 is provided on the grid body, one of which serves as the front air intake. In addition, because the bottom grid 203 is a protruding design, the bottom grid 22 can be inserted into the mounting slot 1032 of the front air intake body 1, thereby better ensuring the accuracy and stability of the relative arrangement position of the bottom grid 22 and the front air intake body 1.

[0095] In addition, the front bumper body 1 of the present invention is provided with a supporting overlapping flange 101 at its edge; the side plate structure of the grille overlaps on the adjacent supporting overlapping flange 101; the supporting overlapping flange 101 is essentially a stepped plate structure set at the edge of the front bumper body 1, mainly used for the overlapping installation of adjacent components.

[0096] In this invention, a positioning protrusion 1011 is provided at the edge of the support overlap flange 101 near the grille assembly groove 11 of the front bumper body 1; adjacent positioning protrusions 1011 are spaced apart; the positioning protrusion 1011 presses against the inner side of the side plate flange 32 of the grille side plate 3; the positioning protrusion 1011 disclosed above in this invention can press against the inner side of the side plate flange 32 during subsequent use to play a good calibration and limiting role, ensuring the accuracy of the relative position of the front bumper body 1 and the grille side plate 3; at the same time, based on this design This design effectively reduces the contact area between the bearing supporting the overlapping flange 101 and the upper side flange of the grille side plate 3, thus reducing the required assembly precision during assembly. In other words, based on the setting of the positioning protrusion 1011, the present invention uses the positioning protrusion 1011 to limit the lateral installation of the supporting overlapping flange 101 and the grille side plate 3, which can reduce the material used for the supporting overlapping flange 101. This avoids the trouble of requiring full-surface fit when the supporting overlapping flange 101 comes into contact with the upper side flange 32 of the grille side plate 3.

[0097] In this invention, the lower grille 2 also includes a daytime running light cover 23, which is embedded in the grille substrate 201. The daytime running light cover 23 is directly installed on the lower grille 2, ensuring the integrity of the lower grille 2 and the daytime running light cover 23. At the same time, in this invention, the daytime running light cover 23 is embedded in the grille substrate 201, which ensures the flatness of the outer side of the lower grille 2.

[0098] A front bumper assembly includes a contrasting color front bumper structure, which can be connected to the vehicle body via mounting brackets 5. The mounting brackets 5 facilitate the installation and assembly of the front bumper assembly on the vehicle body. In actual installation, the contrasting color front bumper structure is generally connected to the vehicle body on both the left and right sides via mounting brackets 5, and the two ends of the front bumper body 1 are also connected to the adjacent fenders via mounting brackets. In this invention, there are various types of mounting brackets 5. The mounting bracket 5 selected in this invention mainly includes a mounting base, on which mounting inserts are provided. The mounting base can be connected to the inner side of the support overlap flange 101 of the front bumper, and the mounting inserts can be inserted into the support frame inside the grille. Based on the use of mounting brackets 5, the accuracy and stability of the front bumper assembly's installation position on the vehicle can be ensured, and the sagging of the front bumper assembly can be avoided.

[0099] An assembly method for the contrasting color front protection structure, the assembly method comprising the following steps:

[0100] Step 1: Component assembly;

[0101] The lower grille, front bumper body, and center grille side panel structures are assembled separately.

[0102] The front bumper body and the side panel structure of the grille are assembled to form a semi-finished product;

[0103] Step 2: Assemble the lower grille and front bumper body;

[0104] After step 1 is completed, install the lower grille onto one set of semi-finished products to form two sets of semi-finished products; connect the middle grille onto the two sets of semi-finished products to form three sets of semi-finished products;

[0105] Step 3: Install the lower air deflector: Place the lower air deflector on the side of the front bumper body away from the grille mounting slot to form the desired contrasting color front bumper structure;

[0106] Step 4: After completing Step 3, the assembly of a contrasting color front guard structure is complete. If reassembly is required, repeat Steps 1-3 above.

[0107] Example:

[0108] The front bumper structure disclosed in this invention consists of four major "color block units": front bumper body 1, lower grille 2, middle grille side plate structure 3, and lower guide plate 4.

[0109] All four are independently injection-molded exterior parts. After each part is painted, they are quickly assembled through a "hidden card-hang-insert" three-in-one interface to form a modular front bumper system that can be colored differently or have individual parts changed in color.

[0110] Front body 1 - Reference coordinates:

[0111] The front bumper body 11 has a grille mounting groove 11 that runs through the X direction of the whole vehicle and is recessed in the Z direction in the middle; the lower part has a main body groove 1031 and several mounting through grooves 1032 that are connected to the main body groove 1031.

[0112] The main body recess 1031 1b has a depth less than the wall thickness of the front bumper body 1 and is used to embed the lower grille 2; the assembly through slot 1032 is a through hole at the front and rear, which allows airflow, radar and daytime running lights to pass through, while providing insertion limit for the local structure of the lower grille 2.

[0113] The front bumper body 11 extends outward along its edge to form a support overlapping flange 101. Positioning protrusions 1011 are arranged at intervals on the inner side of the flange for quick lateral calibration of the grille side panel 33.

[0114] Lower grille 2 – double-splitter embedded;

[0115] The lower grille 2 adopts a split design: a long strip bottom grille 22 and fog light grilles 21 at both ends.

[0116] The bottom grille 22 includes a grille base plate 201 and an integrated license plate plate 202. The license plate plate 202 protrudes forward in the center and has a mounting groove 2021, which can be mounted on the front bumper body 1, specifically on the lower edge of the grille mounting groove 11, to achieve Z-shaped pre-mounting of the bottom grille 22. The back of the grille base plate 201 has a rearward protruding bottom mesh 203, which is inserted into the corresponding mounting through groove 1032 to prevent the grille from shifting.

[0117] Grille side panel structure – symmetrical double-sided mounting;

[0118] The grille side panel structure consists of two symmetrical grille side panels 3.

[0119] Each side panel 3 of the grille has an "L" shaped cross section: the side panel body 31 and the side panel flange 32 are perpendicular to each other. The side panel body 31 is further divided into a first side panel 311, a second side panel 312, and a hook corner 313 at the corner. The three are injection molded as a whole to form a double inverted "L" hook structure of the front bumper hanging groove 301 and the grille hanging groove 302.

[0120] The front bumper mounting groove 301 is attached to the top surface of the support overlap flange 101 to achieve initial positioning in the Y / Z directions;

[0121] The grille mounting slot 302 is attached to the side frame of the grille to ensure that the gap between the grille and the front bumper is matched;

[0122] The inner side of the side panel flange 32 is in full contact with the outer side of the grille, providing Y-axis calibration;

[0123] The back of the side panel body 31 is provided with a plug-in protrusion, which corresponds to the plug-in groove 1012 of the front bumper body 1 to achieve final positioning in the X / Y direction;

[0124] The side panel body 31 is also provided with multiple first insert plates 303 on its edge, which are inserted into the slots of the grille at multiple points; the supporting overlapping flange 101 is provided with a second insert plate 102 at the corresponding position, which is also inserted into the grille, forming a three-in-one hidden insert chain of "body-side panel-grille".

[0125] Lower deflector 4 – airflow guidance & contrasting color finishing touch.

[0126] The lower air deflector 4 is located on the lower edge of the front bumper body 1 and is fixed by a hidden buckle and a positioning tongue. It mainly serves the function of airflow guidance and also acts as the fourth color block unit to form a color contrast with the front bumper body 1.

[0127] Color blocking scheme:

[0128] The four color blocks can be of the same color family or different colors; the conventional scheme adopts the principle of "adjacent different colors", for example:

[0129] The front bumper body 1 is gray, the lower grille 2 is black, the side panel of the grille 3 is silver, and the lower air deflector 4 is black.

[0130] In this invention, all coatings are required to be completed independently before the final assembly of their respective units to ensure that the boundaries are unobstructed and there is no color difference.

[0131] After the contrasting color front bumper assembly is assembled, it can be mounted on the vehicle body using mounting brackets. The assembly method and process for the front bumper assembly on the vehicle are as follows:

[0132] Step 1: Pre-install the bracket:

[0133] Fix the left and right mounting brackets 5 to the vehicle body; the mounting plates of the mounting brackets 5 extend forward and are ready for use.

[0134] Step 2: Production of semi-finished units:

[0135] The bottom grille 22 and fog light grille 21 are connected together to form the "lower grille assembly";

[0136] The front bumper body (1) and the left and right side grille panels (3) are connected together to form a "semi-finished product".

[0137] Step 3: First assembly:

[0138] The lower grille 2 assembly is pushed into the main body groove 1031, the bottom mesh 203 is inserted into the corresponding assembly through groove 1032, the license plate 202 is hung on the front bumper body 1 by the mounting groove 2021, and the four sides are locked by buckles to form "two sets of semi-finished products".

[0139] Step 4: Second assembly

[0140] The grille is pushed into the grille assembly slot 11, and the first insert plate 303 of the grille side plate 3 and the second insert plate 102 supporting the overlapping flange 101 are simultaneously inserted into the grille slot to complete the X / Y / Z omnidirectional positioning and form "three sets of semi-finished products".

[0141] Step 5: Installation of the lower air deflector 4:

[0142] Push the lower air deflector 4 from the inner side of the lower edge of the front bumper body 1 backward, and the hidden buckle will automatically lock, forming a complete color-blocked front bumper structure.

[0143] Step 6: Final vehicle assembly;

[0144] The front bumper assembly is lifted and fitted onto the mounting plate 61 of the corresponding mounting bracket 5 through the grille, thus completing the front bumper structure connection; then the two ends of the front bumper body 1 are fastened to the fender mounting bracket to complete the vehicle assembly.

[0145] Step 7: Quality inspection, manually push each grille to ensure it is not loose; ensure the airflow channel is not obstructed.

[0146] This invention allows for independent spraying and turnover of four color block units, enabling OEMs to achieve mixed production of 24 contrasting color combinations on the same production line without the need for additional tooling.

[0147] After-sales service: Users or 4S stores can replace any color block unit individually to achieve "single-part color change", improving repair economy by 35%.

[0148] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
