Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a front windshield bracket, a preparation method thereof, and an automobile. Background Art

[0002] A car's windshield is typically equipped with a bracket for mounting electronic components. As vehicles become increasingly intelligent, the number of electronic components integrated into the bracket is increasing, including but not limited to rearview mirrors, cameras, rain sensors, ETC (Electronic Toll Collection) devices, 5G modules, dashcams, wiring harness clips, and other electronic components. The bracket is typically attached to the windshield using adhesive tape. As the number of integrated electronic components increases, the bracket's structure becomes increasingly complex and its size increases. This makes it difficult to accurately calibrate the fit between the bracket and the windshield, and the bracket's ends are prone to warping or rebounding during adhesion, impacting the bracket's manufacturing and assembly yields.

[0057] See Figure 1 、 Figure 2 and Figure 3 , Figure 1 and Figure 2 The structural diagram and the exploded diagram of the front block bracket 10 in some embodiments of the present application are shown respectively. Figure 3 for Figure 1 A schematic structural diagram of the frame 11 in the front block bracket 10 shown. The front block bracket 10 provided in the present application can be used in automobiles, for example, it can be adhered to the front windshield of the automobile by any applicable adhesive structure such as 3M tape. The front block bracket 10 can be used to install vehicle-mounted electronic components, for example, it can be used to install any two or more of any applicable vehicle-mounted electronic components such as rearview mirrors, cameras, rain sensors, ETC devices, 5G modules, driving recorders, wiring harness clips, etc. Of course, the above is only one application of the front block bracket 10 of the present application. The front block bracket 10 can also be used to be fixed on any other applicable device, and to install any applicable electronic components or other types of components to achieve integrated installation of components.

[0058] In some embodiments, the front bumper bracket 10 includes a frame 11 and at least two sub-brackets. The frame 11 serves as a supporting structure for the sub-brackets, and the sub-brackets serve as mounting structures for electronic components. Each sub-bracket can be used to mount one or more electronic components. The sub-brackets are connected to the frame 11, and at least two adjacent sub-brackets are spaced apart. In other words, the front bumper bracket 10 forms a hollow area between at least two adjacent and spaced sub-brackets. For example, Figure 1 and Figure 2 In the embodiment shown, taking the front block bracket 10 as an example, the three sub-brackets are provided, namely the first sub-bracket 19, the second sub-bracket 21 and the third sub-bracket 22. The three sub-brackets are arranged in sequence, and a hollow area is formed between the first sub-bracket 19 and the second sub-bracket 21, and a hollow area is formed between the second sub-bracket 21 and the third sub-bracket 22.

[0059] Combine Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, in this embodiment, the first sub-bracket 19 can be a 5G module and ETC device bracket, the second sub-bracket 21 can be a rain sensor bracket, and the third sub-bracket 22 can be a camera bracket. When the front block bracket 10 is installed on the front windshield of the car, the car's 5G module and ETC device are installed on the first sub-bracket 19, the rain sensor is installed on the second sub-bracket 21, and the camera is installed on the camera bracket to achieve the integration of multiple electronic components. Of course, the above is only an example of one embodiment of the sub-bracket of the front block bracket 10. The number of sub-brackets, the structure of each sub-bracket, the type and number of installed electronic components can also have any other applicable designs, which can be specifically designed according to the vehicle-mounted integration requirements and are not limited in this application.

[0060] The aforementioned front windshield bracket 10 is divided into a frame 11 and sub-brackets, with a hollowed-out area formed between at least two sub-brackets. One or more electronic components can be mounted on each sub-bracket. This allows for the integration of multiple electronic components while simplifying the structural complexity of the front windshield bracket 10 and reducing its structural rigidity. This allows the front windshield bracket 10 to be more easily calibrated and more fully adhered to the front windshield. Furthermore, when adhered to the front windshield via the adhesive structure, it is less likely to experience rebound deformation that could affect the fit. Furthermore, this helps reduce stress generated during the molding and calibration of each component, lowering the risk of external stress marks, thereby improving the manufacturing and assembly yields of the front windshield bracket 10. For example, when the front windshield bracket 10 is roughly rectangular, its dimensions can be 350 mm by 200 mm. Using this front windshield bracket 10, the warping deformation at both ends of the front windshield bracket 10 when adhered to the windshield can be controlled to less than 1 mm.

[0061] Please see again Figure 1 、 Figure 2 and Figure 3In some embodiments, the main body 111 of the frame 11 includes a first frame portion 1111, a second frame portion 1112, a third frame portion 1113, and a fourth frame portion 1114. The first frame portion 1111 and the second frame portion 1112 are opposed to each other, and the third frame portion 1113 and the fourth frame portion 1114 are opposed to each other. The first frame portion 1111, the third frame portion 1113, the second frame portion 1112, and the fourth frame portion 1114 are sequentially connected to form an installation space 1115. At least two sub-brackets are connected to the frame 11 within the installation space 1115 and are spaced apart in a direction from the third frame portion 1113 to the fourth frame portion 1114. The first frame portion 1111 and the second frame portion 1112 can be elongated structures of approximately the same length, and the third frame portion 1113 and the fourth frame portion 1114 can be elongated structures of approximately the same length. In this case, the frame 11 can be roughly hollow rectangular, and the direction from the third frame portion 1113 to the fourth frame portion 1114 can be the length direction of the frame 11. Each frame portion may also be an arc or other shape, and the specific design can be based on the installation and local requirements of the vehicle-mounted electronic components. In this embodiment, through the design of the layout of the frame 11 and the sub-brackets, each sub-bracket is located within the installation space 1115 enclosed by the frame 11. The frame 11 can provide good positioning, fixation, and protection for the sub-brackets, while reducing structural rigidity and improving structural strength. It also facilitates the installation and layout requirements of various vehicle-mounted electronic components, fully utilizing multiple sub-brackets for installation, and preventing electronic components installed on each sub-bracket from interfering with each other.

[0062] In some embodiments, the first sub-bracket 19, the second sub-bracket 21, and the third sub-bracket 22 are sequentially spaced apart in the direction from the third frame portion 1113 to the fourth frame portion 1114. The first sub-bracket 19 and the third sub-bracket 22 are located at opposite ends of the direction from the third frame portion 1113 to the fourth frame portion 1114. The first sub-bracket 19 has its ends connected to the first frame portion 1111 and the second frame portion 1112, respectively. The side edge of the first sub-bracket 19 facing away from the third sub-bracket 22 is connected to the third frame portion 1113. The third sub-bracket 22 has its ends connected to the first frame portion 1111 and the second frame portion 1112, respectively. The side edge of the third sub-bracket 22 facing away from the first sub-bracket 19 is connected to the fourth frame portion 1114. The second sub-bracket 21 has its ends connected to the first frame portion 1111 and the second frame portion 1112, respectively. This allows full utilization of the frame 11 to secure and position the three sub-brackets, improving the structural reliability of the front bumper bracket 10. When the sub-brackets include more sub-brackets, the side edges of the sub-brackets located at both ends in the direction from the third frame portion 1113 to the fourth frame portion 1114 can be connected to the third frame portion 1113 and the fourth frame portion 1114 respectively, and the two ends of the other sub-brackets are connected to the first frame portion 1111 and the second frame portion 1112 respectively.

[0063] The fixing method between each sub-bracket and the frame 11 is not limited, as long as the front block bracket 10 is formed with a hollow area through the independent design of the sub-bracket, the structural complexity and structural rigidity of the front block bracket 10 can be reduced. Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, in some embodiments, one of the frame 11 and the sub-bracket is provided with a positioning hole 121, and the other is provided with a positioning pin 23. When the sub-bracket is mounted on the frame 11, the positioning pin 23 is inserted into the positioning hole 121 to achieve the positioning of the sub-bracket on the frame 11. Furthermore, in some embodiments, one of the frame 11 and the sub-bracket is provided with a snap-fit ​​groove 122, and the other is provided with a snap-fit ​​structure 24. When the sub-bracket is mounted on the frame 11, the snap-fit ​​structure 24 is snap-fitted into the snap-fit ​​groove 122 to improve the positioning accuracy and installation reliability of the sub-bracket relative to the frame 11.

[0064] Combine Figure 3-Figure 6 As shown, in some embodiments, the frame 11 includes a main body 111 and a boss 12 protruding from the main body 111 on the side facing the installation space 1115. Positioning holes 121 and snap-fit ​​grooves 122 are provided on the boss 12 at intervals. The sub-bracket is provided with a positioning pin 23 corresponding to the positioning hole 121 and a snap-fit ​​structure 24 corresponding to the snap-fit ​​groove 122. When the sub-bracket is installed on the frame 11, the positioning pin 23 on the sub-bracket is inserted into the positioning hole 121 of the boss 12, and the snap-fit ​​structure 24 on the sub-bracket is snap-fitted into the snap-fit ​​groove 122 of the boss 12. The boss 12 is provided on the inner side of the main body 111 and is positioned and fixed to the sub-bracket through the positioning hole 121 and the snap-fit ​​groove 122. This not only enables the sub-bracket to be positioned and fixed on the frame 11, but also helps to simplify the structural arrangement of the frame 11 and the sub-bracket, thereby reducing the overall occupied space. Furthermore, securing the sub-bracket to the frame 11 via the boss 12 also helps reduce the rigidity of the connection between the frame 11 and the sub-bracket, making it less likely for the front bumper bracket 10 to rebound and produce stress marks during shape correction and adhesion. Of course, in other embodiments, the locating pin 23 and the snap-fit ​​structure 24 can also be located on the boss 12 of the frame 11, and the sub-bracket is then provided with a locating hole 121 corresponding to the locating pin 23 and a snap-fit ​​groove 122 corresponding to the snap-fit ​​structure 24. Alternatively, one of the locating pin 23 and the snap-fit ​​structure 24 can be located on the boss 12, while the other can be located on the sub-bracket, as long as the sub-bracket and the frame 11 can be positioned and secured. In this embodiment, the diameter of the locating pin 23 can be greater than or equal to 2.5 mm and less than or equal to 3.5 mm, and the radial dimension of the locating hole 121 is adapted to that of the locating pin 23. The snap-fit ​​groove 122 can be a square groove, and the dimensions of the snap-fit ​​groove 122 can be 5 mm by 2 mm.

[0065] When the front gear bracket 10 includes multiple sub-brackets, the frame 11 may be provided with multiple bosses 12, each sub-bracket being secured to one or more bosses 12. The number and location of bosses 12 are not limited and can be specifically designed based on the number and location of the sub-brackets. For example, in some embodiments, the frame 11 includes three bosses 12 connected to the first frame portion 1111 and spaced sequentially along the first frame portion 1111, four bosses 12 connected to the second frame portion 1112 and spaced sequentially along the second frame portion 1112, and two bosses 12 connected to the third frame portion 1113 and spaced sequentially along the third frame portion 1113. The first sub-bracket 19 includes four sets of locating pins 23 and snap-fit ​​structures 24. Two sets of locating pins 23 and snap-fit ​​structures 24 located at the side edges are respectively secured to the two bosses 12 connected to the third frame portion 1113, and two sets of locating pins 23 and snap-fit ​​structures 24 located at the ends are respectively secured to the two bosses 12 connecting the first frame portion 1111 and the second frame portion 1112. Two sets of locating pins 23 and snap-fit ​​structures 24 are provided at each end of the second sub-bracket 21. These two sets of locating pins 23 and snap-fit ​​structures 24 are respectively fixedly connected to the two bosses 12 connecting the first frame portion 1111 and the second frame portion 1112, and located between the first sub-bracket 19 and the third sub-bracket 22. A set of locating pins 23 and snap-fit ​​structures 24 at one end of the third sub-bracket 22 is fixedly connected to the boss 12 connecting the first frame portion 1111, while two sets of locating pins 23 and snap-fit ​​structures 24 at the other end are respectively fixedly connected to the two bosses 12 connecting the second frame portion 1112. This arrangement fully utilizes the spatial layout of the frame 11, achieving precise positioning and stable fixation of the three sub-brackets on the frame 11 while reducing the overall size of the front bumper bracket 10.

[0066] It should be noted that in the present application, when the sub-brackets and the frame 11 are relatively independent and connected to each other through structures such as the boss 12, during the assembly process of the front windshield bracket 10, each sub-bracket can be first installed on the frame 11, and then the sub-bracket and the frame 11 as a whole can be adhered to the front windshield through the adhesive structure. In addition, before the sub-brackets are installed on the frame 11, the shape of the frame 11 and the sub-brackets can be corrected to make them more suitable for the shape of the front windshield. In this case, the structure of each component is simple, the size and structural rigidity are small, and correction is easier. It is not easy to rebound deformation when adhering after correction, and it is not easy to produce marks due to stress during the correction process that affect the appearance. Of course, the sub-brackets and the frame 11 can also be assembled and then corrected and adhered. In this case, a hollow area is formed between adjacent sub-brackets, and the connection area between the sub-brackets and the frame 11 is small, which is also conducive to simplifying the structural complexity and structural rigidity of the front windshield bracket 10, thereby improving the production yield and assembly yield during the correction and adhesion process.

[0067] See Figure 11 、 Figure 12 and Figure 13 , Figure 11-13 Another connection method for the sub-bracket and the frame 11 is provided. In some embodiments, one of the frame 11 and the sub-bracket is provided with a connection hole 25, and the other is provided with a connection structure 13. The frame 11 and the sub-bracket are prepared using a two-color injection molding process, and the connection structure 13 is inserted into the connection hole 25. It is understandable that in this embodiment, when preparing the front bumper bracket 10, one of the sub-bracket and the frame 11 provided with the connection hole 25 can be prepared by injection molding first, and then the other can be prepared by second-color injection molding. When preparing the other, part of the injection molding material flows into the connection hole 25 to form the connection structure 13. By preparing the sub-bracket and the frame 11 by two-color injection molding, the positioning accuracy and fixing stability between the sub-bracket and the frame 11 can be improved, thereby improving the structural strength and structural stability of the front bumper bracket 10 while reducing the structural complexity and structural rigidity.

[0068] Combine Figure 14 and Figure 15 As shown, in some embodiments, the connection structure 13 is provided on the boss 12, and the connection hole 25 is provided at the position of the sub-bracket corresponding to the connection structure 13. Two sets of connection structures 13 can be provided on each boss 12, and the position of the sub-bracket corresponding to each boss 12 can be provided with two connection holes 25 corresponding to the connection structure 13 one by one, so as to further improve the connection reliability. Figure 16 and Figure 17 As shown, in some embodiments, when the connection holes 25 are grouped in pairs, the two connection holes 25 in each group of connection holes 25 have different cross-sectional shapes. For example, one connection hole 25 has a circular cross-sectional shape, while the other connection hole 25 has a rectangular cross-sectional shape. Accordingly, one connection structure 13 on the same boss 12 has a circular cross-sectional shape, while the other connection structure 13 has a rectangular cross-sectional shape. By combining different fixing methods, the positioning accuracy and connection reliability between the sub-bracket and the frame 11 can be further improved.

[0069] Further, combined with Figure 15 and Figure 17As shown, in some embodiments, a connection hole 25 is formed in the sub-bracket. A recessed groove 26 is formed on the side of the sub-bracket facing away from the boss 12, communicating with the connection hole 25. The radial dimension of the recessed groove 26 may be larger than that of the connection hole 25, and the recessed groove 26 may be disposed around the connection hole 25. A connection structure 13 is provided on the boss 12 and includes a first connection portion 131 connected to the boss 12, and a second connection portion 132 connected to the side of the first connection portion 131 facing away from the boss 12. The radial dimension of the second connection portion 132 is larger than that of the first connection portion 131. The outer circumference of the first connection portion 131 may conform to the sidewalls of the connection hole 25, and the outer circumference of the second connection portion 132 may conform to the sidewalls of the recessed groove 26. When the sub-bracket is mounted on the frame 11, the first connection portion 131 is inserted into the connection hole 25, and the second connection portion 132 is located within the recessed groove 26 and abuts the bottom wall of the recessed groove 26. Thus, while the sub-bracket and the frame 11 are prepared by the two-color injection molding process to improve positioning accuracy and connection reliability, the second connecting portion 132 can also provide further limiting and fixing effects on the sub-bracket in the axial direction, thereby further improving the structural strength of the front block bracket 10. Figure 11 and Figure 17 In the embodiment shown, the number and arrangement of the sub-brackets and the number and arrangement of the bosses 12 can be the same as Figure 1 The embodiments shown are the same, only the fixing method between the sub-bracket and the boss 12 is different. Of course, different fixing methods can also be combined arbitrarily, and can be specifically designed according to the installation requirements of the sub-bracket. For example, some sub-brackets can be fixed to the boss 12 through the positioning pin 23 and the snap structure 24, and some sub-brackets can be fixed to the frame 11 through a two-color injection molding process.

[0070] See Figure 18In other embodiments, the frame 11 and the sub-bracket may be integrally formed to further enhance the positioning accuracy and connection stability between the frame 11 and the sub-bracket. For example, in some embodiments, the frame 11 includes a first mounting portion 14, a second mounting portion 15, and a third mounting portion 16 spaced apart from each other, and the front bumper bracket 10 includes a first sub-bracket 19, a second sub-bracket 21, and a third sub-bracket 22 spaced apart from each other. The first sub-bracket 19 is integrally formed with the first mounting portion 14, the second sub-bracket 21 is integrally formed with the second mounting portion 15, and the third sub-bracket 22 is integrally formed with the third mounting portion 16. Furthermore, in some embodiments, the first mounting portion 14 and the second mounting portion 15 are interconnected by a first connector 17, the radial dimension of which is smaller than the radial dimensions of the first mounting portion 14 and the second mounting portion 15. The second mounting portion 15 and the third mounting portion 16 are interconnected by a second connector 18, the radial dimension of which is smaller than the radial dimensions of the second mounting portion 15 and the third mounting portion 16. The first sub-bracket 19 , the second sub-bracket 21 and the third sub-bracket 22 are sequentially spaced apart in a direction from the first mounting portion 14 to the third mounting portion 16 .

[0071] This arrangement not only improves the positioning accuracy and connection stability between a single sub-bracket and its corresponding mounting portion through the one-piece injection molding process, but also creates hollow areas between adjacent sub-brackets, reducing the structural complexity and rigidity of the front bumper bracket 10. It also helps reduce the connection rigidity between two adjacent mounting portions, thereby further reducing the structural complexity and rigidity of the front bumper bracket 10, and reducing the risk of deformation and stress marks during the calibration and adhesion processes. It also helps reduce injection molding consumables between two adjacent mounting portions, thereby reducing the manufacturing cost of the front bumper bracket 10.

[0072] It should be noted that in the embodiment where the sub-brackets and the frame 11 are integrally formed, the number, arrangement and relative relationship between the sub-brackets and the frame 11 can be the same as Figure 1 and Figure 11 The embodiment shown is the same, only the connection method of the sub-bracket and the frame 11 is different. In addition, the connection area between the sub-bracket and the frame 11 can be roughly the same as Figure 1 and Figure 11In the illustrated embodiment, the connection areas of the sub-bracket and the boss 12 are comparable, so as to achieve a stable connection between the sub-bracket and the frame 11 while reducing the structural rigidity between the sub-bracket and the frame 11. It will be understood that in this embodiment, the first mounting portion 14 can be considered to be composed of the portion of the first frame portion 1111 connected to the third frame portion 1113, the third frame portion 1113, and the portion of the second frame portion 1112 connected to the third frame portion 1113. The third mounting portion 16 can be considered to be composed of the portion of the first frame portion 1111 connected to the fourth frame portion 1114, the fourth frame portion 1114, and the portion of the second frame portion 1112 connected to the fourth frame portion 1114. The second mounting portion 15 can be considered to be composed of the portion of the first frame portion 1111 located between the first mounting portion 14 and the third mounting portion 16, and the portion of the second frame portion 1112 located between the first mounting portion 14 and the third mounting portion 16.

[0073] refer to Figure 2 As shown, in each of the above embodiments, the frame 11 and the sub-brackets can be provided with retaining ribs 27 that can enclose and form a gluing groove 28. The retaining ribs 27 on the frame 11 can be provided at the opposite inner and outer edges of the frame 11, so that the coverage area of ​​the gluing groove 28 can be roughly adapted to the area of ​​the main body 111 of the frame 11. Alternatively, only a portion of the main body 111 of the frame 11 can be provided with retaining ribs 27 to enclose and form the gluing groove 28. Retaining ribs 27 can be provided at the outer edges of each sub-bracket, so that the coverage area of ​​the gluing groove 28 on the sub-bracket can be roughly adapted to the area of ​​the sub-bracket. Alternatively, only a portion of the sub-bracket can be provided with retaining ribs 27. The specific design can be based on the structure of the frame 11 and the sub-brackets, as well as the bonding requirements of the front windshield bracket 10. During the process of bonding the front windshield bracket 10 to the front windshield, the side provided with the retaining ribs 27 is positioned toward the front windshield, and the front windshield bracket 10 is bonded to the front windshield by injecting glue into the gluing groove 28. In this embodiment, the width of the gluing groove 28 is greater than or equal to 5 mm and less than or equal to 10 mm, and the depth of the gluing groove 28, that is, the height of the retaining rib 27 is greater than or equal to 0.8 mm and less than or equal to 1 mm, which can meet the gluing requirements and is also beneficial to compressing the space occupied by the front block bracket 10.

[0074] Based on the above embodiments, the following also provides several methods for preparing the front windshield bracket 10 when the connection methods between the sub-bracket and the frame 11 are different. Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, when the sub-bracket and the frame 11 are positioned and fixed to each other by the positioning pin 23 and the snap structure 24, the preparation method of the front bumper bracket 10 may include:

[0075] Prepare a frame 11, which includes a main body 111 and a boss 12 protruding from the inner side of the main body 111. The boss 12 is provided with positioning holes 121 and locking grooves 122 spaced apart from each other;

[0076] Prepare at least two sub-brackets, each of which is provided with a positioning pin 23 and a snap structure 24;

[0077] At least two sub-brackets are installed on the frame 11 at intervals, such that the positioning pins 23 on the sub-brackets are inserted into the positioning holes 121, and the snap structures 24 are inserted into the snap-fit ​​grooves 122. In this embodiment, both the frame 11 and the sub-brackets can be manufactured using an injection molding process. In this embodiment, the material of the frame 11 includes, but is not limited to, a mixture of polypropylene (PP) and glass fiber (GF), a mixture of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS), a mixture of polybutylene terephthalate (PBT) and GF, or a mixture of PBT and glass beads (GB), which helps to improve the structural strength of the frame 11 and reduce the risk of deformation of the frame 11. The material of each sub-bracket includes but is not limited to a mixture of PC and ABS, ABS, Acrylonitrile Styrene Acrylate (ASA), PP or Polyethylene (PE) and other materials with good fluidity, which can adapt to the complex structure of the sub-bracket, reduce the generation of stress marks, and improve the molding yield.

[0078] Combine Figure 11-14 As shown, in some embodiments, when the sub-bracket and the frame 11 are connected by a two-color injection molding process, the preparation method of the front bumper bracket 10 may include:

[0079] First color injection molding, injection molding to produce at least two sub-brackets, each sub-bracket having a connecting hole 25, and a side of the sub-bracket also having a sink 26 connected to the connecting hole 25;

[0080] Second-color injection molding is performed to produce the frame 11, wherein part of the injection molding material flows to the connecting hole 25 to form the first connecting part 131, and part of the injection molding material flows to the sink 26 to form the second connecting part 132 connected to the first connecting part 131. The radial dimension of the second connecting part 132 is larger than the radial dimension of the first connecting part 131. The remaining injection molding material is formed into the boss 12 and the main body 111 of the frame 11. The boss 12 is connected to the side of the first connecting part 131 facing away from the second connecting part 132, and the main body 111 is connected to the boss 12.

[0081] In this embodiment, the first-color injection molding material can be a mixture of PC and ABS, ABS, ASA, PP or PE and other materials with good fluidity, which can adapt to the complex structure of the sub-bracket, reduce the generation of stress marks, and improve the molding yield. The second-color injection molding material can be a mixture of PC and ABS, a mixture of ABS, PP and GF, a mixture of PBT and GF, or ASA and other materials, which are beneficial to improving the structural strength of the frame 11 and reducing the risk of deformation of the frame 11.

[0082] refer to Figure 18 As shown, in an embodiment where the sub-bracket and the frame 11 are integrally formed, the method for preparing the front bumper bracket 10 may include:

[0083] Place a first connecting member 17 and a second connecting member 18 spaced apart from each other on the injection mold;

[0084] The first bracket structure, the second bracket structure and the third bracket structure are prepared by injection molding. The first bracket structure includes an integrated first sub-bracket 19 and a first mounting portion 14, the second bracket structure includes an integrated second sub-bracket 21 and a second mounting portion 15, and the third bracket structure includes an integrated third sub-bracket 22 and a third mounting portion 16. The first mounting portion 14 and the second mounting portion 15 are spaced apart and connected by a first connecting member 17, and the second mounting portion 15 and the third mounting portion 16 are spaced apart and connected by a second connecting member 18.

[0085] By pre-placing the first connector 17 and the second connector 18 in the injection mold, three mounting portions and three sub-brackets can be simultaneously produced through a single injection molding process, effectively simplifying the manufacturing process of the front bumper bracket 10 and reducing manufacturing costs. Of course, in other embodiments, the first, second, and third bracket structures can be separately produced through injection molding, and then the three bracket structures can be connected by any suitable connection method, such as snap-fit, interference fit, or threaded connection, via the first connector 17 and the second connector 18. In this embodiment, the three sub-bracket structures can be made of a material with good fluidity, such as a blend of PC and ABS, ABS, ASA, PP, or PE. This can accommodate the complex structure of the sub-brackets, reduce the generation of stress marks, and improve the molding yield. The first connector 17 and the second connector 18 can utilize a structure such as a rib. The first connector 17 and the second connector 18 can be roughly cuboid, with the length, width, and height of the first connector 17 and the second connector 18 being 5mm*5mm*2.5mm.

[0086] In the various preparation methods involved above, the structure of each component, the number and layout of the sub-brackets, the relative relationship between the sub-brackets and the frame, and the corresponding technical effects can be obtained by referring to the above records and will not be repeated in this application.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
