Description

Technical Field

[0001] This utility model belongs to the technical field of automotive driver assistance system accessories, specifically relating to a bracket for an in-vehicle intelligent network L4 auxiliary radar system. Background Technology

[0002] With the development of my country's social economy, automobiles, as a means of transportation, are becoming a rapidly developing industry. The number of cars is increasing, and so are the traffic accidents. More than 90% of these accidents are caused by car collisions, resulting in damage to vehicles and property, or even injuries and fatalities. Traffic accidents have become a major social problem and a focus of widespread public concern and eager anticipation for significant breakthroughs in improving living standards. To address these issues, installing radar, cameras, and other detection equipment, combined with intelligent control systems such as lane departure warning systems, distance warning systems, and vehicle stability control systems, can significantly reduce the accident rate. However, existing vehicle radar systems mostly use forged parts, which are heavy and bulky. Furthermore, current vehicle radar brackets have limited functionality, hindering modular vehicle layout and production. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a vehicle-mounted auxiliary radar system bracket, which can integrate multiple functional components, greatly reducing the weight of the bracket and providing stable control for the overall control system.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vehicle-mounted auxiliary radar system bracket, including a main crossbeam, two side brackets symmetrically installed at both ends of the main crossbeam, and the two side brackets are respectively connected to the corresponding vehicle frame ends; a middle bracket is welded to the middle of the main crossbeam, and the middle bracket is connected to the radar; a horn fixing bracket is welded to one side of the main crossbeam, and an electric horn is connected to the horn fixing bracket.

[0005] The side support includes a front base, one end of which is connected to the main crossbeam. An annular groove is left between the front base and the main crossbeam. The other end of the front base is connected to a first connecting base, a second connecting base, and a third connecting base. The second connecting base is located between the first connecting base and the third connecting base.

[0006] The first connecting base is provided with four first bases. Adjacent first bases are connected by arc-shaped connecting sections. The arc-shaped connecting sections between adjacent first bases are all concave structures. The first base is a cylindrical structure and has a first connecting through hole. To reduce the weight of the first connecting base while ensuring its structural strength, two first weight-reducing through holes are provided on the first connecting base. The first weight-reducing through holes follow the structural arrangement of the first connecting base and are approximately triangular through holes.

[0007] To reduce the weight of the second connecting base while ensuring its structural strength, weight-reducing grooves are provided on both sides of the second connecting base. The inner corners of the weight-reducing grooves are rounded, and the weight-reducing grooves on both sides are arranged symmetrically.

[0008] The third connecting base is provided with two third bases, each with a cylindrical structure and a third through hole. The third connecting base is provided with a trailer hook hole, which can be connected to a trailer hook. In order to reduce the weight of the third connecting base while ensuring its structural strength, a third weight-reducing through hole is provided on the third connecting base. There are two connecting through holes on the third connecting base.

[0009] The intermediate support includes a positioning plate, one end of which has a raised groove, and the other end of which has a tail plate, which is welded to the main crossbeam. One side of the positioning plate has a first ear plate, the first outward flange of which is welded to the main crossbeam. The other side of the positioning plate has a second ear plate, the length of which is less than that of the first ear plate, and the second outward flange of which is welded to the main crossbeam. The first ear plate, the second ear plate, the positioning plate and the main crossbeam form a semi-enclosed structure. A square weight-reducing through hole is opened in the middle of the positioning plate.

[0010] The horn mounting bracket and the intermediate bracket are located on both sides of the main crossbeam. The horn mounting bracket has a horn connection hole, and the bolt passes through the horn connection hole to connect to the electric horn.

[0011] The outer side of the second connecting base is provided with a first concave arc segment. One end of the first concave arc segment is connected to the first connecting base, and the other end of the first concave arc segment is connected to the third connecting base. The lateral width of the second connecting base is smaller than the lateral width of the first connecting base, and the lateral width of the second connecting base is smaller than the lateral width of the third connecting base.

[0012] To avoid stress concentration, the inner corners of the two first weight-reducing through holes are rounded, the inner corners of the third weight-reducing through hole are rounded, and the inner corners of the square weight-reducing through hole are rounded.

[0013] The two third bases are connected by a second concave arc segment. One of the third bases is connected to the base through the third concave arc segment. While ensuring the structural strength of the third connecting base, the weight of the third connecting base is further reduced.

[0014] Compared with the prior art, the specific advantages of this utility model are as follows: This utility model connects to both ends of the front frame of the vehicle body by arranging two side brackets, and arranges a middle bracket and a horn fixing bracket on the main crossbeam. It is equipped with three major control systems: lane departure warning, distance warning and vehicle stability control, realizing the integration of multiple assembly functions; This utility model changes from traditional forging to casting and stamping welding, reducing the weight from 18kg to 10kg, which is 44.4% lighter than the original casting structure; The welding technology of this utility model adopts automatic welding and fixing by welding robots, ensuring the stable quality of the welded product; The overall structural design of this utility model is reasonable, with good versatility, and can be widely promoted and applied.

The first base 221 is a cylindrical structure and has a first connecting through hole 244. To reduce the weight of the first connecting base 22 while ensuring its structural strength, two first weight-reducing through holes 222 are provided on the first connecting base 22. The first weight-reducing through holes 222 conform to the structural arrangement of the first connecting base 22 and are approximately triangular through holes. During installation, bolts pass through the corresponding first connecting through holes 244 on the first base 221 and are connected to the end of the frame.
