[0002] Lightweight stamped metal door anti-collision beams are an important automotive safety structural component. They are manufactured using high-strength metal materials and stamping processes, and installed inside the door. Their main function is to effectively absorb and disperse collision energy in the event of a side collision, preventing excessive deformation of the door, thereby protecting the survival space of passengers inside the vehicle, reducing injuries to passengers in collision accidents, and also helping to maintain the overall structural stability of the vehicle and improve its safety performance. Currently, lightweight vehicles mostly use a one-piece stamping process for their stamped metal door anti-collision beams and doors. When a door suffers a minor collision that causes the anti-collision beam to deform, sheet metal repair of the door is usually required. However, although the repaired anti-collision beam may have returned to its original shape, its internal metal structure has been altered. This alteration weakens the protective performance of the anti-collision beam, thus adversely affecting the vehicle's safety. Therefore, a lightweight stamped metal door anti-collision beam for vehicles is proposed to address the above problems. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: A lightweight stamped metal car door anti-collision beam includes an anti-collision beam assembly 1, a fixing seat assembly 2 inserted into the inner side of the anti-collision beam assembly 1, and an anti-detachment assembly 3 installed inside the fixing seat assembly 2. The anti-collision beam assembly 1 includes an anti-collision beam body 11, a positioning hole 12 is opened on the inner side of the anti-collision beam body 11, and an iron plate 13 is fixedly connected to the inner side of the positioning hole 12. The fixing seat assembly 2 includes a positioning seat 21, one end of which has a ramp 22, a guide groove 23 and an insertion hole 24. A spring 25 is fixedly connected to the inner side of the guide groove 23, and a guide block 26 is slidably connected to the inner side of the guide groove 23. The guide block 26 and the permanent magnet post 27 are integrally fixed structures. The outer side of the anti-collision beam body 11 is fitted with the inner side of the ramp 22, and the permanent magnet post 27 is inserted into the inside of the positioning hole 12.

[0017] As a further implementation of this solution, the upper and lower ends of the anti-collision beam body 11 are both provided with a rightward convex slope. The inner side of the anti-collision beam body 11 is provided with an internal groove 14 and a weight reduction hole 15. Through the above-mentioned settings, this design not only improves the structural strength of the anti-collision beam body 11, enabling it to better withstand impact forces, but also reduces the overall weight through the internal groove 14 and the weight reduction hole 15, achieving the dual advantages of lightweight and high strength, and further improving the vehicle's fuel efficiency and performance. As a further implementation of this solution, the iron sheet 13 is attached to the permanent magnet column 27, and the iron sheet 13 and the permanent magnet column 27 are magnetically attracted to each other. Through the above arrangement, the convenience of replacing the anti-collision beam assembly 1 is improved. As a further implementation of this solution, one end of the ramp 22 is an inclined structure. The ramp 22, guide groove 23, and insertion hole 24 are connected. Both the front and rear ends of the guide groove 23 extend with sliding grooves. Through the above-mentioned configuration, the assembly between components is smoother, and the assembly efficiency is improved. At the same time, the connected structural design ensures the uniform distribution of force, reduces local stress concentration, and further enhances the protective performance of the anti-collision beam. As a further implementation of this solution, the spring 25 is fixedly connected to the guide block 26, the guide block 26 is located inside the groove of the guide groove 23, the permanent magnet column 27 is clearance-fitted with the inner side of the guide groove 23, and the shape of the permanent magnet column 27 matches the shape of the positioning hole 12. Through the above settings, the permanent magnet column 27 can smoothly enter the positioning hole 12, ensuring the precise assembly between components. The fixed connection between the spring 25 and the guide block 26 enhances the stability of the structure and improves the anti-deformation ability of the anti-collision beam when it is impacted. As a further implementation of this solution, the anti-detachment component 3 includes an anti-detachment rod 31. The front end of the anti-detachment rod 31 has a spiral strip 33. The anti-detachment rod 31 is threadedly connected to the internal threaded cylinder 32 through the spiral strip 33. The rear end of the internal threaded cylinder 32 is tightly attached to the positioning seat 21 at the front end. A baffle is provided at the rear end of the anti-detachment rod 31. The anti-detachment rod 31 is inserted into the inside of the insertion hole 24. The outer side of the anti-detachment rod 31 is clearance-fitted with the permanent magnet post 27. Through the above settings, a tight connection between the components is ensured. At the same time, the baffle prevents the components from accidentally falling off, enhances the stability and reliability of the entire structure, and further improves the safety performance of the vehicle.

[0018] Workflow: During use, the positioning seat 21 is fixed to the car door. A layer of plastic partition is attached to both the top and bottom of the anti-collision beam body 11. This prevents the permanent magnet post 27 from prematurely inserting into the positioning hole 12 during installation. The anti-collision beam body 11 is then horizontally inserted into the grooves 22 created by the multiple positioning seats 21. After the anti-collision beam body 11 is fully inserted, the plastic partition is removed. By adjusting the front and rear position of the anti-collision beam body 11, the guide groove 23 is aligned with the positioning hole 12. After alignment, the magnetic attraction between the iron sheet 13 and the permanent magnet post 27 causes the permanent magnet post 27 to be inserted into the positioning hole 12. The magnetic column 27 moves into the positioning hole 12, driving the guide block 26 to move. The guide block 26 slides inside the guide groove 23, pressing against the spring 25. When not installed, the spring 25 allows the permanent magnet column 27 to be embedded in the guide groove 23. After multiple permanent magnet columns 27 enter the positioning hole 12 through the magnetic attraction of the iron sheet 13, the anti-collision beam body 11 cannot move forward or backward or up or down. Then, the anti-detachment rod 31 is inserted into the insertion holes 24 of the multiple positioning seats 21. The anti-detachment rod 31 is then inserted through the spiral openings of the internal threaded cylinder 32 and the anti-detachment rod 31. The 33-spiked installation uses anti-detachment rods 31 to block the permanent magnet column 27, preventing it from detaching from the positioning hole 12, thus completing the installation. The slope of the upper end of the anti-collision beam body 11 and the cooperation of the groove 22 enhance the fixing strength of the anti-collision beam body 11. The built-in groove 14 and weight-reducing hole 15 in the anti-collision beam body 11, along with the shape of the anti-collision beam body 11, reduce the increase in weight. Multiple positioning seats 21 fix the anti-collision beam body 11, improving the uniformity of impact force distribution. The distributed design of multiple positioning seats 21 can... This significantly reduces the likelihood of damage to the positioning seat 21 after an impact. When disassembling the anti-collision beam body 11, an existing permanent magnet block, whose magnetic attraction strength is twice that between the permanent magnet column 27 and the iron sheet 13, is placed at one end of multiple positioning seats 21. The permanent magnet column 27 is reset by magnetic attraction. Based on the above principles, the device not only ensures the protection performance of the car door after a collision, but also allows the anti-collision beam to be replaced without replacing the car door, reducing economic losses and ensuring the effectiveness of the door protection again.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
