[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 lower guard plate, 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. Traditional front bumper panels have a large body size and are prone to deformation due to one-piece injection molding; for example, the front bumper structure disclosed in patent: 201920034158.9 - a front bumper device for reducing wind resistance.

[0006] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the structure or assembly process of the existing front bumper assembly. Summary of the Invention

[0078] Step 3: After completing Step 2, install the two semi-finished front bumper parts onto the grille 2;

[0079] Step 4: Install the air deflector below the center grille 2;

[0080] Step 5: After completing Step 4, one front bumper assembly is installed. If you need to reassemble a new front bumper assembly, repeat Steps 1-4.

[0081] 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. At the same time, by assembling the corresponding semi-finished parts in stages and then integrating them into the final assembly, this invention can improve the assembly efficiency of the front bumper assembly to a certain extent.

[0082] Furthermore, the front bumper body 1 of this invention is provided with vent holes 101; the vent holes 101 facilitate the passage of air through the front end of the front bumper body, which can reduce the wind resistance of the front bumper to a certain extent, thereby reducing the overall vehicle running resistance; at the same time, the vent holes 101 are connected to the air curtain shell 5; the air curtain shell includes an air curtain body 501, and the air curtain body 501 is provided with an airflow channel 502; the air curtain shell 5 is an airflow guiding device, which facilitates the control of the airflow direction, and in subsequent use, it can control the airflow at the front of the car to quickly pass through the vehicle body and be discharged outside the vehicle body as needed, thereby reducing wind resistance.

[0083] Specifically, in this invention, the airflow channel 502 is inclined and arranged towards the side of the vehicle tire. To achieve the above operation, a through-hole groove is provided at the corresponding position on the outer wheel cover of the tire. The through-hole groove is arranged opposite to the outlet end of the airflow channel 502. Based on this setting, the airflow can be directly discharged to the wheel cover area, reducing the airflow in the front bumper area entering the front compartment and increasing the vehicle's running resistance. At the same time, the airflow groove disclosed in this invention is oriented towards the tire, which also plays a role in removing debris and cooling, reducing debris on the tire and increasing the airflow velocity around the tire, which to a certain extent increases the cooling speed of the brake assembly connected to the tire.

[0084] Furthermore, in this invention, the front bumper body also includes a decorative element, which includes a vent decorative element; the front bumper body is provided with vent holes; the vent holes are connected to air curtain shells; the vent decorative element is installed inside the vent holes of the front bumper body; the air curtain shell overlaps both the vent decorative element and the front bumper body.

[0085] Specifically, the front bumper body 1 is provided with a vent 101. In this invention, the vent 101 facilitates airflow through the front end of the front bumper body, which can reduce the wind resistance of the front bumper to a certain extent, thereby reducing the overall vehicle resistance.

In subsequent use, it can control the airflow at the front of the car to quickly pass through the vehicle body and be discharged, thereby reducing wind resistance.

[0086] Specifically, in this invention, the airflow channel 502 is inclined and arranged towards the side of the vehicle tire. To achieve the above operation, a through-hole groove is provided at the corresponding position on the outer wheel cover of the tire. The through-hole groove is arranged opposite to the outlet end of the airflow channel 502. Based on this setting, the airflow can be directly discharged to the wheel cover area, reducing the airflow in the front bumper area entering the front compartment and increasing the vehicle's running resistance. At the same time, the airflow groove disclosed in this invention is oriented towards the tire, which also plays a role in removing debris and cooling, reducing debris on the tire and increasing the airflow velocity around the tire, which to a certain extent increases the cooling speed of the brake assembly connected to the tire.

[0087] Specifically, the air curtain body 501 in this invention includes an air curtain base plate 51, and an air curtain side plate 52 is provided around the air curtain base plate 51. The air curtain side plate 52 is connected to adjacent components through an air curtain flange 53. In this invention, the air curtain base plate 51 and the air curtain side plate 52 form a box structure with an opening on the bottom and one side. This arrangement facilitates the placement of the air curtain body 501 on the inner wall of the front bumper 11. At the same time, an air curtain flange 53 is provided at the edge of the air curtain side plate, and the air curtain flange 53 can be connected to the front bumper 11 by adhesive or welding. In actual connection, the air curtain flange 53 can generally be attached to the inner wall of the front bumper 11 or the vent decoration by a sealing strip. Then, it is fixed to the vent decoration 4 or the front bumper 11 by screws.

[0088] Specifically, in this invention, the air curtain side plate 52 is provided with a connecting end plate 54, and the connecting end plate 54 is provided with a fixing hole. In actual connection, the connecting end plate 54 is attached to the mounting flange 111 at the end of the front bumper body 1. At the same time, in order to ensure the normal flow of airflow, the mounting flange 111 is provided with an avoidance through hole. The airflow channel 502 is connected to the avoidance through hole, and the connecting end plate 54 is attached to the inner side of the mounting flange 111. It is then locked with screws. This setting greatly ensures the installation and fixation of the air curtain shell 5 on the front bumper body 11.

[0089] Specifically, the front bumper body in this invention also includes a decorative component; the decorative component includes a vent decorative component 4; the vent decorative component 4 facilitates the filling of the vent 101, preventing debris from entering the inner side of the front bumper through the vent 101; simultaneously, the vent decorative component 4 in this invention includes a decorative body; the decorative body includes a decorative base plate 41, the decorative base plate 41 is provided with ventilation holes, and the ventilation holes are provided with ventilation mesh; the ventilation holes are mainly used for communication, preventing the vent decorative component from blocking the vent 101 and affecting the air intake of the front bumper body. Operation; simultaneously, the decorative substrate 41 of the present invention is provided with a snap-fit ​​groove 411; the snap-fit ​​groove 411 is distributed around the ventilation hole, and the snap-fit ​​groove 411 is provided with a plurality of snap-fit ​​slots 412; the air curtain shell 5 overlaps on the ventilation hole decorative part 4; in subsequent use, a snap-fit ​​ring plate is provided at the edge of the ventilation hole 101, and the snap-fit ​​ring plate is inserted into the snap-fit ​​groove 411, which plays a good mutual limiting role, greatly ensuring the limiting and fixing of the ventilation hole decorative part 4 on the front bumper 11; and better ensuring the stability of the connection between the ventilation hole decorative part 4 and the front bumper 11.

[0090] Specifically, during actual connection, the air curtain base plate overlaps the decorative base plate; at the same time, during subsequent connection, screws or bolts can be used to connect to the front guard body by passing through both the air curtain shell and the decorative body; at the same time, the ventilation holes are required to be covered inside the air curtain shell. This design better ensures the flow of gas.

[0091] Specifically, in this invention, a bonding and pressing plate 42 is provided at the edge of the decorative substrate 41. The bonding and pressing plate is connected to the outer side of the decorative substrate 41. The bonding and pressing plate 42 simultaneously presses against the inner wall of the front bumper 11 and the inner wall of the flange. Based on this arrangement, the accuracy of the installation position of the vent decorative part 4 is well guaranteed. At the same time, in this invention, the bonding and pressing plate 42 includes an inner side plate 421 connected to the decorative substrate 41. The inner side plate 421 is provided with an end pressing step plate 422. In actual connection, the inner side plate 421 is bonded to the inner wall of the front bumper 11, and simultaneously presses against the inner side plate 422. The side panel 421 is provided with a top-pressing stepped plate 422 at its end. The top-pressing stepped plate 422 abuts against the inner wall of the flange at the upper end of the front bumper 11, which plays a good role in longitudinal positioning. At the same time, in actual design, the top-pressing stepped plate 422 is a stepped plate structure with its own stepped platform. The flange at the upper end of the front bumper 11 and the contact point with the top-pressing stepped plate 422 are also designed as a stepped structure. This design makes the ventilation hole decorative piece 4 and the front bumper 11 mutually position and limit each other, which better ensures the accuracy and stability of the installation position of the ventilation hole decorative piece 4 on the front bumper 11.

[0092] Specifically, the grille 2 in this invention includes a grille body, which includes a main grille 21. An overlapping plate 22 is provided at the edge of the main grille 21. The overlapping plate 22 is essentially an extension plate added to the edge of the main grille 21. This design facilitates the overlapping of the grille 2 onto adjacent components during subsequent use, effectively ensuring the connection between the front bumper 11 and the grille body. Simultaneously, the overlapping plate 22 in this invention has an overlapping groove 22-1, which contains an overlapping slot. The overlapping groove 22-1 is located on the side of the overlapping plate 22 closest to the main grille 21. The overlapping groove 22-1 is arranged along the outer periphery of the main grille 21. This design facilitates the subsequent overlapping of peripheral components of the main grille 21 onto the grille 2. The overlapping slot facilitates connection with snap-fit ​​fasteners on adjacent components, greatly simplifying the connection and assembly between the grille 2 and adjacent components.

[0093] Furthermore, the front bumper body in this invention also includes a lower guard plate and an overlapping connecting plate; the lower guard plate and the overlapping connecting plate are respectively connected to both sides of the grille; in this invention, the two sides mainly refer to the upper and lower sides of the grille; as shown in the attached drawings.

[0094] Furthermore, the front bumper body in this invention also includes a lower guard plate 3. The lower guard plate 3 prevents stones or other debris from entering the front compartment through the lower end of the front bumper during vehicle operation, reducing damage to the engine or belts. Simultaneously, the lower guard plate 3 also has a certain airflow guiding effect, reducing the amount of gas entering the front compartment and decreasing overall vehicle running resistance. Additionally, the lower guard plate 3 in this invention includes a guard plate body 31, with a guard plate overlap 32 on the body. The guard plate body 31 overlaps with the grille 2 via the guard plate overlap 32. The guard plate overlap 32 and the guard plate body 31 form a stepped plate. This design allows the overlap between the front bumper body and the lower guard plate 3 to have mutual positioning functions when the lower guard plate 3 overlaps with the front bumper body, better ensuring the accuracy and stability of the lower guard plate 3's installation position.

[0095] Furthermore, the front bumper body in this invention also includes an overlapping connecting plate 7, which is distributed at the end of the front bumper body away from the lower guard plate 3. The setting of the overlapping connecting plate 7 is equivalent to increasing the size of the upper surface of the grille 2, which facilitates the overlapping installation at the upper end of the front compartment. At the same time, the overlapping connecting plate 7 also plays a role in blocking water, preventing rainwater from seeping into the front compartment through the overlapping plate body 22.

[0096] In other words, the overlapping connecting plate disclosed in this invention is arranged above the central grille. By setting the overlapping connecting plate 7, this invention effectively increases the size of the upper surface of the central grille 2, facilitating overlapping installation at the upper end of the front compartment. Simultaneously, the overlapping connecting plate 7 also serves as a water barrier, preventing rainwater from seeping into the front compartment through the overlapping plate body 22. In actual design, the overlapping connecting plate disclosed in this invention includes a first connecting plate 71, a second connecting plate 72, and a middle connecting plate 73. The first connecting plate 71 and the second connecting plate 72 are staggered and connected by the middle connecting plate 73. When the first connecting plate 71 is arranged, its vertical distance from the horizontal plane is greater than that of the second connecting plate 72 from the horizontal plane; here, the horizontal plane can be considered as the horizontal plane of this component. After assembly onto the vehicle, the vehicle is parked on a horizontal surface. The first connecting plate 71 and the second connecting plate 72 are arranged laterally, while the middle connecting plate 73 is arranged at an angle. Based on this arrangement, the overlapping connecting plate disclosed in this invention forms a stepped plate. During subsequent installation and connection, the overlapping plate above the grille body overlaps the second connecting plate 72, and the second connecting plate 72 is fixed to the front beam of the front compartment at the same time as the overlapping plate. Bolts or screws are used to connect the overlapping plate and the second plate to the front beam. At the same time, in this invention, the end of the overlapping plate above the grille body is required to press against the connection between the middle connecting plate 73 and the second connecting plate 72. This arrangement plays a good role in calibration and limiting, and ensures the accuracy and stability of the position when the overlapping connecting plate is connected to the grille body.

[0097] Meanwhile, the second plate has a longitudinal connecting flange 74 at one end near the grid body. The longitudinal connecting flange 74 can be fixedly connected to the grid body with screws to better ensure the stability of the connection between the grid body and the overlapping connecting plate.

[0098] In addition, a plug-in hole 76 is provided on the middle connecting plate 73, and a plug-in plate 75 is provided at the end of the overlapping plate above the grid body. In use, the plug-in plate 75 is inserted into the plug-in hole, which plays a good positioning role and prevents the overlapping plate from tilting on the overlapping connecting plate. This reduces the stress on the screws and better ensures the stability of the connection between the grid body and the overlapping connecting plate.

[0099] Furthermore, in this invention, each of the front bumper bodies is provided with a vent hole, and each vent hole is used in conjunction with a vent hole decorative piece and an air curtain shell; this arrangement enables both sides of the front bumper body to have a ventilation function, facilitating the passage of gas through the front bumper assembly and reducing the wind resistance of the front bumper assembly.

[0100] An assembly method for the aforementioned modular front bumper assembly; the assembly method includes the following steps:

[0101] Step 1: Select the various components of the front bumper assembly;

[0102] Step 2: First, install the corresponding vent decorative parts on the corresponding front bumper; then install the air curtain shell on the front bumper to form a semi-finished front bumper.

[0103] At the same time, overlapping connecting plates are installed on the central grille;

[0104] Step 3: After completing Step 2, install the two semi-finished front bumper parts onto the grille.

[0105] Step 4: Install the air deflector below the grille;

[0106] Step 5: After completing Step 4, one front bumper assembly is installed. If you need to reassemble a new front bumper assembly, repeat Steps 1-4.

[0107] Furthermore, in this invention, the grille is provided with a support mechanism, which includes overlapping brackets disposed on the grille; the support mechanism includes two overlapping brackets, which are distributed at both ends of the grille; the overlapping brackets are connected to the grille body through grille protrusions; the overlapping brackets are connected to the grille protrusions by welding; when the front bumper assembly is assembled on the vehicle; it is required that the overlapping brackets overlap the front bumper of the car and connect to the front end of the vehicle frame; the grille 2 is connected to the front end of the car body through overlapping connecting plates; here, the front end of the car body mainly refers to the front end of the car body. Above the front compartment; specifically, it is required that when the front bumper assembly is assembled on the vehicle; the overlapping bracket is connected to the front end of the vehicle frame; the grille is connected to the upper part of the front compartment of the vehicle through the overlapping connecting plate; based on the above operation method, the present invention enables the central area of ​​the grille 2 to have a direct connection with the front end of the car, better ensuring the stability of the installation of the front bumper assembly and the front end of the car; in addition, in the present invention, through the setting of the overlapping connecting plate, the overlapping connecting plate is equivalent to a bridge plate, one end of the overlapping connecting plate is connected to the upper end of the grille 2, and the other end is arranged on the upper end of the front beam of the front compartment, thereby realizing the binding and fixing of the upper end of the front bumper assembly.

[0108] Specifically: In this invention, the grille body is provided with a support mechanism 9, which includes an overlapping bracket 91 connected to the grille body; the setting of the overlapping bracket 91 is equivalent to increasing the connection position between the front bumper and the whole vehicle, that is, increasing the connection point between the front bumper assembly and the whole vehicle. This setting greatly ensures the stability of the connection between the front bumper assembly and the whole vehicle.

[0109] Meanwhile, the bracket mechanism 9 in this invention includes two overlapping brackets 91, which are distributed at both ends of the grille body. In specific connection, the overlapping brackets 91 are connected to the frame of the front end of the car body by screws or bolts. This makes the front bumper assembly equivalent to having two fixed connections to the car body frame, which means that the front bumper assembly will be directly supported by the entire vehicle frame, better ensuring the stability of the installation position of the front bumper assembly and avoiding the problem of the front bumper assembly sagging and misaligning easily when using a single buckle connection.

[0110] In addition, in this invention, the overlapping bracket is required to be connected to the grille body through the grille protrusion 92. In actual connection, the overlapping bracket and the grille protrusion 92 can be fixedly connected by welding, or bolts can be used to pass through both the overlapping bracket and the grille protrusion 92 to achieve the connection between the two. In this invention, the grille protrusion 92 serves two purposes: one is to increase the structural strength at the corners of the grille body, and the other is to extend the length of the overlapping bracket, which facilitates the connection with the front frame of the car.

[0111] Meanwhile, in this invention, the overlapping bracket and the grille protrusion 92 are connected by overlapping. In specific use, with the whole vehicle as a reference point, the grille protrusion 92 overlaps on top of the overlapping bracket. This setting allows the overlapping bracket to provide longitudinal support for the grille body and the entire front bumper assembly, reducing the stress at the connection between the overlapping bracket and the grille body. If the overlapping bracket is connected above the grille protrusion 92, the connection between the overlapping bracket and the grille protrusion 92 will be subjected to a tensile force, which may easily cause the connection between the two to detach, thereby affecting the stability of the connection between the grille protrusion 92 and the overlapping bracket.

[0112] Meanwhile, in this invention, the overlapping bracket and the grille protrusion 92 are arranged in an overlapping manner. In actual use, the overlapping position of the overlapping bracket and the grille protrusion 92 can be changed. In other words, the overlapping bracket disclosed in this invention can be applied to the connection and assembly of different models of front bumpers on the vehicle body, which greatly improves the applicability of the overlapping bracket.

[0113] During actual installation and assembly, it is required to determine the distance between the front bumper assembly and the front of the car. After the distance is determined, the overlapping bracket is then fixedly connected to the grille protrusion.

[0114] Meanwhile, in this invention, each front bumper and the grille are connected by an overlap limiting part 1-1. In this invention, the overlap limiting part 1-1 is distributed at the lower end of the front bumper and the grille. The overlap limiting part 1-1 includes a supporting longitudinal plate 1-12 provided on the side end of the front bumper and a hanging longitudinal plate 1-11 provided on the side end of the grille. The hanging longitudinal plate 1-11 has a hanging block 1-13 at the end away from the grille. In actual installation and connection, the supporting longitudinal plate 1-12 and the hanging longitudinal plate 1-11 are arranged close to each other, and the hanging block 1-13 is hung on the end of the supporting longitudinal plate 1-12. Then, the bolts pass through the hanging longitudinal plate 1-11 and the supporting longitudinal plate 1-12, which can better ensure the stability of the connection between the front bumper and the grille.

[0115] In actual arrangement, the overlapping limiting part 1-1 of the present invention also plays a good role in lateral limiting, preventing the grille and front bumper from laterally swaying.

[0116] In addition, the overlapping limiting part 1-1 disclosed in this invention forms a cooperative relationship with the snap-fit ​​connection between the grille and the front bumper, which better ensures the stability of the relative position of the grille relative to the front bumper and better ensures the integrity of the front bumper assembly. At the same time, the hanging block 1-13 plays a good longitudinal support role, so that the grille is equivalent to being hung on the front bumper, ensuring the accuracy of the relative position of the grille and the front bumper.

[0117] In this invention, the overlapping limiting parts 1-1 are distributed on both sides of the lower end of the grille, and the lower end of the grille is connected to the adjacent front bumper body through an overlapping limiting part 1-1.

[0118] Furthermore, in step 2 of this invention, the air curtain shell 5 is required to simultaneously overlap the decorative part of the vent 101 and the inner wall of the front bumper 11; the air curtain shell 5 is connected to the decorative part of the vent 101 and / or the front bumper 11 by screws; this connection method facilitates the connection between the air curtain shell 5 and the decorative part of the vent 101 and the inner wall of the front bumper 11. At the same time, the screws pass through the air curtain shell 5 and connect to the decorative part of the vent 101 and / or the front bumper 11, so that the air curtain shell 5 also acts as a restraining member, ensuring the stability of the decorative part of the vent 101 installed on the front bumper 11.

[0119] Furthermore, in this invention, the two front bumper panels, the corresponding vent 101 decorative parts, and the air curtain shell 5 are assembled simultaneously at different workstations; this arrangement allows for the assembly of different components in sections, thereby improving the assembly efficiency of the front bumper assembly to a certain extent.

[0120] Obviously, the specific implementation of this invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
