Abstract
Description
Technical Field
[0001] This utility model relates to the installation structure of the front-end module of an automobile. Background Technology
[0002] The front-end module (FEM) of a car includes components such as the radiator, hood, headlights, and cooling module. The front-end module is mounted on the front of the body-in-white (BIW) via a front-end module bracket.
[0003] Front-end module brackets are typically a single, integral structure. For example, they may be molded from aluminum alloy and then riveted (or welded) together to form a single unit. They can also be molded from fiber-reinforced plastics. Alternatively, they can be molded from a mixture of fiber-reinforced plastics and metal.
[0004] The aforementioned integrated front-end module bracket has a high production investment cost, requiring specialized tooling such as molding equipment, welding robots, and fixtures. When the integrated front-end module bracket is partially damaged due to a vehicle collision, the entire front-end module bracket needs to be replaced, thus increasing the user's maintenance costs.
[0005] Furthermore, collisions between vehicles and pedestrians are common traffic accidents. Although low-speed vehicles are sometimes not fatal, when the rigid front bumper beam of a car acts on a pedestrian's lower leg, if other parts below the bumper beam are not rigid enough, the bending moment generated by the bumper beam acting on the lower leg and foot, respectively, can cause a lower leg fracture. To avoid injuries in such accidents, a lower reinforcement is installed below the front bumper beam. This lower reinforcement, together with the front bumper beam, forms a rigid and stable structure to increase the contact area with the lower leg during a collision, thereby preventing the lower leg from experiencing a large bending moment and thus avoiding a lower leg fracture.
[0006] Figure 16 A schematic diagram is shown of a prior art lower reinforcement member mounted on the front of the body-in-white via an integrated front-end module bracket.
[0007] like Figure 16 As shown, the integrated front-end module bracket 100' is mounted on the front of the body-in-white 200, and the bumper beam 300 is mounted on the front of the integrated front-end module bracket 100'. Below the front bumper beam 300, the lower reinforcement 400 is mounted on the integrated front-end module bracket 100' via the lower reinforcement mounting bracket 500.
[0008] Clearly, a separate lower reinforcement mounting bracket 500 is required for the integrated front-end module bracket 100'. This obviously increases the number of parts and the assembly process, thereby adding unnecessary costs.
[0009] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0110] It should be understood that the accompanying drawings are not necessarily drawn to scale, and illustrate, to some extent, simplified features of the basic principles of the present invention. Specific design features of the present invention disclosed herein, including, for example, specific dimensions, orientations, positioning, and shapes, will be determined in part by the specific purpose and environment of use.
[0111] In these accompanying drawings, and in the multiple figures throughout the drawings, reference numerals refer to the same or equivalent parts of the present invention. Detailed Implementation
[0112] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. These exemplary embodiments are examples and can be implemented in various different forms by those skilled in the art. Therefore, the present invention is not limited to the exemplary embodiments described herein.
[0113] The front-end module of the vehicle (including components such as radiators, hoods, headlights, cooling modules, etc.) is installed at the front of the body-in-white (BIW) through the front-end module bracket of the present utility model. It should be noted that for the convenience of clearly showing the structure of the present utility model, the structure of the front-end module (FEM) is not drawn in the respective drawings of the present application.
[0114] Figure 1 Shows an application schematic diagram of the first embodiment of the front-end module bracket with an insertion connection structure of the present utility model.
[0115] As Figure 1 shown, through the front-end module bracket 100 with an insertion connection structure of the present utility model, the front bumper beam 300 is installed on the body-in-white (BIW) 200.
[0116] Figure 2 Shows the first embodiment of the front-end module bracket with an insertion connection structure of the present utility model.
[0117] As Figure 2 shown, the front-end module bracket with an insertion connection structure of the present utility model is formed by inserting and fixing an upper cross beam 1, a lower cross beam 2, a left column 31, a right column 32, 2 U-shaped pins 4 and 2 lower insertion pins 5 to each other, and is fastened by a plurality of bolts 6. The specific connection relationships of the components will be described in the subsequent part.
[0118] Figure 3 Shows a perspective view of the upper cross beam 1 and its partial enlarged view. <了
[0119] As Figure 3 shown, the upper cross beam 1 is a column with a "field" - shaped cross section, thereby forming four upper beam pin holes 1 - 6 that penetrate in the length direction, and it has two end faces 1 - 1. The upper cross beam 1 forms upper assembly holes 1 - 2 that penetrate up and down near both ends. The upper assembly holes 1 - 2 have an end wall surface adjacent to the end face 1 - 1 and an inner cross section 1 - 4 facing the end wall surface. The center of the end wall surface 1 - 有着1 has an end wall through hole 1 - 3, and the center of the inner cross section 1 - 4 has a side screw hole 1 - 5. The side screw hole 1 - 5 and the end wall through hole 1 - 3 are coaxially arranged. Figure 3 The upper assembly hole 1 - 2 shown is a square hole, but this is not the necessary shape, as long as the shape can meet the assembly relationship.
[0120] The upper cross beam 1 is set as a columnar profile with a "field" - shaped cross section, which helps to ensure rigidity to the greatest extent while reducing weight, and the four upper beam pin holes 1 - 6 formed thereby constitute a locking structure that cooperates with a locking pin (the locking pin in the attached drawings is exemplified by the U - shaped pin 4) (this will be described below). Figure 3 The outer contour of the upper cross beam 1 shown is square. Obviously, a non - square rectangular cross section or even other shaped outer contours are also allowed.
[0121] Of course, if lightweight materials are used, a solid column structure for the upper crossbeam 1 is also permissible. In this case, axially extending upper beam pin holes 1-6 are formed on the two end faces 1-1 of the upper crossbeam 1 for engaging with locking pins for locking. Alternatively, the upper beam pin holes 1-6 can extend through the entire upper crossbeam 1, further reducing weight.
[0122] Figure 4 The image shows a three-dimensional view of the lower crossbeam 2 and a magnified view of its parts.
[0123] like Figure 4 As shown, the lower crossbeam 2 has a hollow structure along its length. The hollow structure helps reduce weight while ensuring component stiffness. Of course, a hollow structure is not mandatory; it is sufficient as long as the design requirements for stiffness and weight are met.
[0124] In the accompanying drawings of this utility model, the main body of the lower crossbeam 2 has a rectangular cross-section in the middle. The front-to-back dimension of this rectangle is larger than its vertical dimension, thus the lower crossbeam 2 is a flat-shaped component. This flat rectangular cross-section structure helps to make the dimensions in the height direction more compact, but other cross-sectional shapes are also possible while meeting design requirements.
[0125] The lower crossbeam 2 has through-holes 2-1 at both ends. Forwardly protruding protrusions 2-2 are formed at both ends of the lower crossbeam 2. A through-hole 2-3 is formed on each protrusion 2-2. An upper through-hole 2-6 is formed on the upper wall of the through-hole 2-3, and a lower screw hole 2-5 is formed on the lower wall of the through-hole 2-3. The lower screw hole 2-5 and the upper through-hole 2-6 are coaxially aligned. A rear insertion port 2-4 is formed on the rear side wall of the lower assembly hole 2-1. The front insertion port 2-3 and the rear insertion port 2-4 are identical in shape and aligned with each other.
[0126] Figure 5A A three-dimensional view of the left column 31 and its enlarged partial view are shown.
[0127] like Figure 5A As shown, the left column 31 includes a wide left main body, an upper left column 31-2 extending upward from the left main body, and a lower left column 31-3 extending downward from the left main body. A left mounting seat 31-1 is formed on the front surface of the left main body, and the left mounting seat 31-1 is provided with a left front screw hole 31-4 for mounting the left end of the front bumper beam by bolt engagement.
[0128] The contour of the upper left column 31-2 can mate with the inner surface of the upper mounting hole 1-2. On the upper left column 31-2, a left front pin groove 31-5 extending through the left and right sides is formed on the front surface, and a left rear pin groove 31-6 extending through the left and right sides is formed on the rear surface. When the upper left column 31-2 is installed in the upper mounting hole 31-2, the positions of the left front pin groove 31-5 and the left rear pin groove 31-6 are aligned with two of the upper beam pin holes 1-6. A left upper column through hole 31-7 is provided between the left front pin groove 31-5 and the left rear pin groove 31-6.
[0129] The lower left post 31-3 has a lower left post pin hole 31-8 that extends forward and backward.
[0130] Figure 5B The image shows a three-dimensional view of the right column 32 and a magnified view of its parts.
[0131] like Figure 5B As shown, the right column 32 includes a wide right main body portion, an upper right column 32-2 extending upward from the right main body portion, and a lower right column 32-3 extending downward from the right main body portion. A right mounting base 32-1 is formed on the front surface of the right main body portion, and the right mounting base 32-1 is provided with a right front screw hole 32-4 for mounting the right end of the front bumper beam by bolt engagement.
[0132] The outline of the upper right column 32-2 can mate with the inner surface of the upper mounting hole 1-2. On the upper right column 32-2, a right front pin groove 32-5 extending through the right side is formed on the front surface, and a right rear pin groove 32-6 extending through the right side is formed on the rear surface. When the upper right column 32-2 is installed in the upper mounting hole 32-2, the right front pin groove 32-5 and the right rear pin groove 32-6 are aligned with two positions in the upper beam pin hole 1-6. A through hole 32-7 for the upper right column is provided between the right front pin groove 32-5 and the right rear pin groove 32-6.
[0133] The lower right column 32-3 has a lower right column pin hole 32-8 that extends forward and backward.
[0134] In the examples shown in the accompanying drawings of this application, the left column 31 and the right column 32 are different components, and they have a symmetrical structure. This arrangement is to bring the assembly axis between the upper and lower crossbeams closer to the center of the front module bracket, thereby enhancing the compactness and overall strength of the structure. It should be noted that it is also permissible for the left column 31 and the right column 32 to be two column components with the same structure, in which case the column components themselves have a symmetrical structure.
[0135] It should also be noted that the left front pin slot 31-5, left rear pin slot 31-6, right front pin slot 32-5, and right rear pin slot 32-6 are used as a pin channel to cooperate with the upper beam pin hole 1-6 of the "field"-shaped upper crossbeam 1 and the U-shaped pin 4. If a common locking pin is used to replace the U-shaped pin 4, the pin channel can be a common lock pin hole.
[0136] Figure 6 The schematic diagram of the U-shaped pin 4 is shown.
[0137] As Figure 6 shown, the U-shaped pin 4 includes a pin bottom plate 4-1 and two pin legs 4-2 extending from the pin bottom plate 4-1 to the same side. The pin legs 4-2 are shaped to match the upper beam pin hole 1-6, left front pin slot 31-5, left rear pin slot 31-6, right front pin slot 32-5, and right rear pin slot 32-6. A side pin through hole 4-3 is formed between the two pin legs 4-2 at the center of the pin bottom plate 4-1.
[0138] Figure 7 The schematic diagram of the lower insertion pin 5 is shown.
[0139] As Figure 7 shown, the lower insertion pin 5 consists of a pin rod 5-1 and a pin head 5-2. A lower pin through hole 5-3 is formed through the pin rod 5-1 from top to bottom. The contour of the pin rod 5-1 matches the shape of the front plug-in port 2-3 and the rear plug-in port 2-4.
[0140] The assembly process of the front-end module bracket with an insertion connection structure of the present utility model is described below.
[0141] Step 1:
[0142] As Figure 8 shown, first insert the upper left column 31-2 of the left column 31 into the upper assembly hole 1-2 at the left end of the upper crossbeam 1, and insert the upper right column 32-2 of the right column 32 into the upper assembly hole 1-2 at the right end of the upper crossbeam 1. Figure 8 The arrow "Z1" in shows the moving direction of the upper crossbeam 1 during the insertion process.
[0143] Step 2:
[0144] As Figure 9 shown, after Step 1, insert the lower left column 31-3 of the left column 31 into the lower assembly hole 2-1 at the left end of the lower crossbeam 2, and insert the lower right column 32-3 of the right column 32 into the lower assembly hole 2-1 at the right end of the lower crossbeam 2. Figure 9 The arrow "Z2" in shows the moving direction of the lower crossbeam 2 during the insertion process.
[0145] Step 3:
[0146] As Figure 10As shown, after step 2, the upper crossbeam 1, lower crossbeam 2, left column 31, and right column 32 are fixed together using two U-shaped pins 4 and two lower pins 5. The two pin legs 4-2 of the left U-shaped pin 4 are inserted into the left upper beam pin hole 1-6, left front pin groove 31-5, and left rear pin groove 31-6; the two pin legs 4-2 of the right U-shaped pin 4 are inserted into the right upper beam pin hole 1-6, right front pin groove 32-5, and right rear pin groove 32-6. The pin rod 5-1 of the left lower pin 5 passes sequentially through the left rear insertion port 2-4, left lower column pin hole 31-8, and left front insertion port 2-3; the pin rod 5-1 of the right lower pin 5 passes through the right rear insertion port 2-4, right lower column pin hole 32-8, and right front insertion port 2-3.
[0147] Figure 10 The arrows in the diagram indicate the direction of movement of the relevant components during insertion. Arrow "X1" indicates the direction of movement of the lower pin 5, arrow "Y1" indicates the direction of movement of the left U-shaped pin 4, and arrow "Y2" indicates the direction of movement of the right U-shaped pin 4.
[0148] Step 4:
[0149] like Figure 11 As shown, after step 3, multiple bolts 6 are used to fasten the upper crossbeam 1, lower crossbeam 2, left column 31, right column 32, U-shaped pin 4, and lower pin 5 together. At this time, the pin 5-1 of the lower pin 5 protrudes beyond the front insertion port 2-3 of the lower crossbeam 2. The two upper bolts 6 pass through the side pin through hole 4-3, the end wall through hole 1-3, and the left upper column through hole 31-7 (or the right upper column through hole 32-7) in sequence, and are tightened in the side screw hole 1-5. The two lower bolts 6 pass through the upper through hole 2-6 and the lower pin through hole 5-3 in sequence, and are tightened in the lower screw hole 2-5.
[0150] In the above embodiments, the through holes or threaded holes for mating with bolts 6 are formed on the upper crossbeam 1, lower crossbeam 2, left column 31, right column 32, U-pin 4, and lower pin 5 during the manufacturing process of the parts. It should be noted that these through holes or threaded holes can also be formed on-site after the upper crossbeam 1, lower crossbeam 2, left column 31, right column 32, U-pin 4, and lower pin 5 have been connected. The choice of method depends on the equipment and process conditions; the goal is to achieve a secure and fixed connection between the components.
[0151] After the above steps, the final result is formed Figure 2 The present invention is illustrated by a front-end module bracket with an insertion connection structure. The front bumper beam 300 is mounted on the body-in-white (BIW) 200 via this front-end module bracket 100, thereby constituting... Figure 1 The installation structure is shown.
[0152] like Figure 11 As shown, the pin 5-1 of the lower pin 5 protrudes beyond the front insertion port 2-3 of the lower crossbeam 2, and this protruding part can be used to install the lower reinforcement 400. Therefore, compared with the structure in the background section, the front module bracket with the insertion connection structure of this utility model no longer requires a separate lower reinforcement mounting bracket 500, thus simplifying the structure and reducing costs.
[0153] The front-end module bracket 100 of this utility model may also have one or more component insertion interfaces for convenient installation of other required components in a plug-in connection structure.
[0154] Figure 12 The front-end module bracket 100 shown has two component insertion interfaces: a left column insertion interface 31-9 on the left column 31 and a right column insertion interface 32-9 on the right column 32. The external component 600 to be inserted has a tenon 600-1, which can be inserted into both the left column insertion interface 31-9 and the right column insertion interface 32-9, thereby achieving quick and reliable insertion and fixing.
[0155] It should be noted that the component insertion interface does not necessarily have to be located on the left column 31 and the right column 32, but can be located at any position on the front module bracket 100 of this utility model as needed. Although Figure 12 The component insertion interface is set on the front module bracket 100, while the tenon 600-1 is set on the external component 600. However, the reverse setting is also allowed, that is, the component insertion interface is set on the external component 600, while the tenon 600-1 is set on the front module bracket 100.
[0156] Figure 13 A second embodiment of the front module bracket with an insertion connection structure of the present invention is shown.
[0157] Compared to the first embodiment, the second embodiment differs in that the lower pin 5 has a double-pin structure, namely, it includes two pins 5-1, both pins 5-1 having a common pin head 5-2, and each pin 5-1 having a through-hole 5-3 extending vertically. Figure 14 As shown. The common pin 5-2 is a long rod, preferably with a forward-convex arc-shaped structure.
[0158] In the assembly process of the front module bracket with the insertion connection structure of this utility model, for the second embodiment, the installation method of the two U-shaped pins 4 in step 3 of the assembly is the same as that in the first embodiment, so it will not be described again. However, the left pin 5-1 of the lower pin 5 with the double pin structure is inserted from front to back (X2 direction) into the left front insertion port 2-3, the left lower post pin hole 31-8 and the left rear insertion port 2-4, and the right pin 5 is inserted from front to back into the right front insertion port 2-3, the right lower post pin hole 32-8 and the right rear insertion port 2-4, thereby completing step 3, as shown. Figure 15 As shown.
[0159] For step 4 (i.e., the step of fixing with bolts), the second embodiment is exactly the same as the first embodiment, so it will not be described again.
[0160] although Figure 13 , Figure 14 , Figure 15 In the second embodiment shown, a left column 31 and a right column 32 are used. Obviously, it is also feasible to replace the left column 31 and the right column 32 with two columns of the same structure.
[0161] In the second embodiment, since the pin head 5-2 is a long rod-shaped structure, it can serve as a lower anti-collision beam, so it is not necessary to install the lower reinforcement 400.
