Technical Field

[0001] This application relates to the field of vehicle body technology, and more particularly to a multi-functional rear fender mounting bracket and automobile. Background Technology

[0002] With the increasing popularity of automobiles in my country, consumers have higher and higher requirements for automobile quality, especially the matching gaps in automobile appearance. The matching of existing automobile fenders with many parts such as sound insulation pads, lower trim panels and mudguards is a key and difficult point in automobile appearance matching. This is because the matching quality of the fender with the surrounding structure is easily affected by factors such as the dimensional accuracy of the fender mounting bracket, the structural strength and rigidity, and the installation method of the fender. Therefore, the structural design of the fender mounting bracket plays a crucial role in the matching quality of the fender.

[0003] Currently, fenders, sound insulation pads, lower trim panels, and mudguards are installed on the vehicle body using different brackets, resulting in complex, time-consuming, costly, and space-consuming assembly. Given the technical problems of redundant brackets in current automotive assembly, which lead to excessive assembly load, time consumption, high costs, and space occupation, it is necessary to develop a multi-functional mounting bracket that integrates fenders, sound insulation pads, lower trim panels, and mudguards. Utility Model Content

[0004] This application addresses the problems of complex, time-consuming, costly, and space-consuming assembly caused by redundant brackets in current automobile assembly. It provides a multi-functional mounting bracket that integrates fenders, sound insulation pads, lower trim panels, and mudguards, simplifying the number of brackets required for automobile assembly and reducing the assembly time of fenders, the cost of required brackets, and the space occupied by the required brackets in the vehicle body.

[0005] To achieve the above objectives, in a first aspect, this application provides a multifunctional rear fender mounting bracket, comprising: a frame body, consisting of a metal plate; the metal plate having a first mounting portion, a second mounting portion formed by bending one side of the first mounting portion downwards, a third mounting portion formed by bending the opposite side of the second mounting portion upwards, a first frame welding portion formed by bending the side of the first mounting portion between the second mounting portion and the third mounting portion, and a second frame welding portion formed by bending the side of the third mounting portion near the first frame welding portion; the first mounting portion having a lower trim panel mounting hole and a fender mounting hole extending longitudinally through the metal plate; the second mounting portion having a mudguard mounting hole; and the third mounting portion having a sound insulation pad mounting hole.

[0007] In some embodiments of this application, the third mounting portion is provided with a clearance groove for accommodating the car frame on the side near the second frame welding portion; the side metal plate of the first mounting portion is bent downward to form the first frame welding portion.

[0008] In the technical solution, the avoidance groove improves the fit between the rear mounting bracket of the multi-functional fender and the shape of the car frame, increases the utilization rate of the vehicle body space, and helps to reduce the space occupied by the vehicle body.

[0009] In some embodiments of this application, the metal plate of the first skeleton welding portion near the second mounting portion is bent to form a reinforcing portion, the reinforcing portion is located on the side of the second mounting portion near the third mounting portion, and the reinforcing portion is welded to the second mounting portion.

[0010] In the technical solution, the reinforcing part provides auxiliary support for the second mounting part, which helps to improve the structural strength at the bend between the first and second mounting parts, thereby improving the structural reliability and service life of the lower mounting bracket at the rear of the multi-functional fender. Welding the reinforcing part to the second mounting part further enhances its supporting effect on the second mounting part.

[0011] In some embodiments of this application, the reinforcing part, the first skeleton welding part, and the second skeleton welding part all have pressure weld joints.

[0012] In this technical solution, the first frame welding part is welded to the car frame, the second frame welding part is welded to the car frame, and the reinforcing part is welded to the second mounting part through pressure welding. The welding time is short, the welding cost is low, and the welding has little impact on the structure of the multi-functional fender rear mounting bracket and the car frame.

[0013] In some embodiments of this application, at least one first stamping groove is provided at the bend between the first mounting portion and the second mounting portion; at least one second stamping groove is provided at the bend between the first mounting portion and the third mounting portion; the first stamping groove is recessed inward at the bend between the first mounting portion and the second mounting portion; the second stamping groove is recessed inward at the bend between the first mounting portion and the third mounting portion; the first mounting portion is provided with at least one third stamping groove; and the third mounting portion is provided with at least one fourth stamping groove recessed toward the first mounting portion.

[0015] In some embodiments of this application, the third stamping groove protrudes upward.

[0020] In the technical solution, the first mounting part is designed to cooperate with the installation of the lower trim panel and to create a certain angle between the horizontal plane and the mounting part. At this time, the horizontal plane of the fixture mounting groove can be used as a reference plane to cooperate with the fixture of the automated welding equipment, so as to quickly determine the automated welding horizontal reference plane of the lower mounting bracket of the multi-functional fender. Based on this, the automated welding reference origin of the lower mounting bracket of the rear of the multi-functional fender can be quickly determined by cooperating with multiple fixture mounting holes.

[0021] In some embodiments of this application, the fixture mounting slots correspond one-to-one with the fixture mounting holes, and each fixture mounting hole is connected to its corresponding fixture mounting slot; all fixture mounting slots are located on the same side of the first mounting part.

[0022] In the technical solution, the one-to-one correspondence between the fixture mounting slot and the fixture mounting hole helps to reduce the area of ​​the fixture mounting slot in the first mounting part and reduce the impact of the fixture mounting slot on the structural strength of the first mounting part.

[0023] Secondly, this application provides an automobile having the aforementioned multi-functional rear fender mounting bracket.

[0024] In this technical solution, the number of brackets required for car assembly is simplified, which helps to reduce the assembly time, cost and size of the car.

[0044] In this technical solution, the present application provides a multi-functional mounting bracket integrating a fender, sound insulation pad, lower trim panel, and mudguard. This simplifies the number of brackets required for automobile assembly, reduces assembly difficulty, assembly time, and bracket costs, and achieves efficient utilization of the vehicle's interior space. Furthermore, the welding of the first frame welding part 4 and the second frame welding part 5 to the vehicle frame not only achieves the connection between the bracket and the vehicle frame but also improves the structural strength of the bracket itself. The bracket structure provided by this application is simple, easy to manufacture, and inexpensive.

[0045] Furthermore, the bending radius of the frame is 1.25-3 times the thickness of the frame to ensure better structural strength.

[0051] Furthermore, a perforation 9 is provided between the first mounting part 1, the second mounting part 2, the first frame welding part 4, and the reinforcing part 6 to reduce the possibility of mutual interference between the first mounting part 1, the second mounting part 2, the first frame welding part 4, and the reinforcing part 6 when bending metal plates to produce the frame, thereby reducing the difficulty of frame processing and improving frame processing efficiency.

[0052] In some embodiments of this application, the reinforcing part 6, the first skeleton welding part 4, and the second skeleton welding part 5 all have pressure weld points 7.

[0053] In this technical solution, the first frame welding part 4 is welded to the car frame, the second frame welding part 5 is welded to the car frame, and the reinforcing part 6 is welded to the second mounting part 2 by pressure welding process. The welding time is short, the welding cost is low, and the welding has little impact on the structure of the multi-functional fender rear mounting bracket and the car frame.

[0054] Furthermore, the first frame welding part 4 has multiple pressure welding points 7 to improve the welding strength between the first frame welding part 4 and the automobile frame.

[0060] In the technical solution, the first mounting part 1 is designed to cooperate with the installation of the lower trim panel to create a certain angle between the horizontal plane and the mounting part. At this time, the horizontal plane of the fixture mounting groove 14 can be used as a reference plane to cooperate with the fixture of the automated welding equipment, so as to quickly determine the automated welding horizontal reference plane of the lower mounting bracket of the multi-functional fender. Based on this, the automated welding reference origin of the lower mounting bracket of the rear of the multi-functional fender can be quickly determined by cooperating with multiple fixture mounting holes 13.

[0061] Furthermore, the angle between the first mounting part 1 and the horizontal plane is 3-5°.

[0062] Furthermore, the vertical distance from the furthest point of the clamp mounting slot 14 to the horizontal groove wall of the clamp mounting slot 14 is 2mm-0.5mm, so as to reduce the impact of the clamp mounting slot 14 on the structural strength of the frame.

[0063] Furthermore, the fixture mounting groove 14 is a milled fixture mounting groove 14 to ensure the positional accuracy of its horizontal groove wall surface.

[0064] Furthermore, the clamp mounting groove 14 is provided on the top surface of the first mounting part 1.

[0066] In the technical solution, the one-to-one correspondence between the fixture mounting groove 14 and the fixture mounting hole 13 helps to reduce the area of ​​the fixture mounting groove 14 in the first mounting part 1 and reduce the impact of the fixture mounting groove 14 on the structural strength of the first mounting part 1.

[0067] In some embodiments of this application, at least one first stamping groove 81 is provided at the bend between the first mounting portion 1 and the second mounting portion 2; at least one second stamping groove 82 is provided at the bend between the first mounting portion 1 and the third mounting portion 3; the first stamping groove 81 is recessed inward at the bend between the first mounting portion 1 and the second mounting portion 2; the second stamping groove 82 is recessed inward at the bend between the first mounting portion 1 and the third mounting portion 3; the first mounting portion 1 is provided with at least one third stamping groove 83; and the third mounting portion 3 is provided with at least one fourth stamping groove 84 recessed toward the first mounting portion 1.

[0069] Furthermore, the clamp mounting hole 13, the mudguard mounting hole 21, the lower trim panel mounting hole 11, the fender mounting hole 12, the sound insulation pad mounting hole 31, the first stamping groove 81, the second stamping groove 82, the third stamping groove 83, and the fourth stamping groove 84 are complementary and overlapping to avoid mutual influence between the above structures, which would lead to a decrease in the local structural strength of the frame.

Multiple second stamping grooves 82 are provided along the length of the bend between the first mounting portion 1 and the third mounting portion 3.

[0071] Furthermore, the bending points of the frame are areas of high stress concentration when the frame is under load. Therefore, deeper first stamped grooves 81 and second stamped grooves 82 are needed to form a more significant triangular reinforcement structure, thereby improving local bending stiffness and dispersing stress. For this reason, the depths of the first stamped groove 81 and second stamped groove 82 are greater than the depths of the third stamped groove 83 and fourth stamped groove 84.

[0072] Furthermore, the depth of the first stamping groove 81 and the second stamping groove 82 is 2-5 times the thickness of the frame, and the depth of the third stamping groove 83 and the fourth stamping groove 84 is 1-3 times the thickness of the frame.

[0073] Furthermore, multiple mudguard mounting holes 21 are provided along the horizontal length direction of the second mounting part 2, and the mudguard mounting holes 21 and the first stamping groove 81 are arranged intersectingly.

[0074] Furthermore, the sound insulation pad mounting hole 31 is intersected with the second stamping groove 82, and the fourth stamping groove 84 is intersected with the second stamping groove 82.

[0078] In the technical solution, the third stamping groove 83 protrudes upward, reducing the possibility of interference between the third stamping groove 83 and the lower trim panel below the first mounting part 1.

[0079] In some embodiments of this application, the side of the third mounting part 3 away from the first frame welding part 4 is a bevel 33, the top of which is inclined toward the first frame welding part 4, so as to reduce the possibility of interference between the frame and other structures of the vehicle.

[0080] In some embodiments of this application, all sharp corners of the frame are rounded to prevent scratches during handling and assembly.

[0081] In some embodiments of this application, the frame is a galvanized steel plate frame or an aluminum alloy frame, which has good strength, toughness and corrosion resistance, and has high structural strength and long service life.

[0082] Furthermore, the frame structure is HC220YD+Z50 / 50-M. In HC220YD+Z 50 / 50-M, HC represents high-strength steel for cold forming, 220 represents a minimum yield strength of 220 MPa, YD represents interstitial steel, +Z represents hot-dip pure zinc coating, and 50 / 50 indicates that the frame structure is galvanized on both sides with a zinc layer weight of 50 g / m² on each side. 2 -M represents a medium zinc spangle finish.

[0083] In some embodiments of this application, the frame must meet the preset CAE stiffness analysis target value, the frame structure design must consider lightweight and corrosion resistance requirements, and the frame structure design should avoid causing welding deformation.
