[0002] In a minor side collision accident, the door and the door anti-collision beam will only produce slight deformation and still have a certain use value. At this time, the door and the door anti-collision beam can be straightened through sheet metal. After straightening, the protective strength of the door and the door anti-collision beam will not be affected, thereby reducing the economic losses in the collision accident.

[0003] However, in some side collision accidents, when the door anti-collision beam is deformed, it will pull the mounting seats on both sides, causing the mounting seats to tilt under the action of external impact force, and pull the screw on the mounting seat, causing the mounting seat or the screw to tilt. At this time, the door anti-collision beam that is still valuable to use is difficult to remove, and needs to be removed and replaced by cutting and other methods, which is not conducive to reducing the economic losses in car collision accidents. In addition, the size and shape of the door anti-collision beam are single. When the door sizes of different models are different, and the front and rear doors of the same car are different in size, door anti-collision beams of different specifications are needed.

[0024] Step 6: Then assemble the energy absorption and positioning assembly onto the two hat-shaped anti-collision beams.

[0025] Preferably, the energy-absorbing positioning assembly is formed by welding a slider on the outside of the cylinder, a fixed plate welded to the inside of the cylinder, and a spring 2 welded between the insertion rod and the fixed plate, and then welding the top rod and the screw rod to each other, and then assembling the nut and the screw rod in the cylinder, and welding the rotating cylinder to the threaded tube.

[0026] As described above, the novel door anti-collision beam and the manufacturing method thereof in the present invention have the following characteristics and advantages:

[0027] Through the cooperation between the cap-shaped cover plate and the clamping block, when the door anti-collision beam is slightly hit and only slightly bent, the clamping block is pressed into the sliding cavity so that the clamping block is no longer clamped in the clamping hole 2, so that the cap-shaped cover plate can be pulled toward the direction of the cap-shaped anti-collision beam 1. At this time, the ends of the two cap-shaped anti-collision beams 2 away from the cap-shaped anti-collision beam 1 lose their limit, so that the cap-shaped anti-collision beams 1 and 2 can be directly taken out, avoiding the situation that the screw rod is skewed when the door anti-collision beam is deformed and it is difficult to take out the door anti-collision beam, which is convenient for taking out and straightening the slightly deformed door anti-collision beam, or directly replacing it;

[0028] Through the energy absorption positioning component matched with the card block, when the hat-shaped anti-collision beam 1 is deformed toward the direction of the vehicle interior, since the two hat-shaped anti-collision beams 2 are fixedly connected with the two mounting seats through the card block at this time, when the hat-shaped anti-collision beam 1 is deformed, the plug hole will pull the plug rod passing through the hat-shaped anti-collision beam 2, and the plug rod will be locked under the action of the screw rod, so that the plug hole is deformed and cracked under the external impact and the pulling action of the plug rod, and then the plug hole away from the middle part of the hat-shaped anti-collision beam 1 is continuously in contact with the plug rod and deformed and cracked, so as to achieve the effect of secondary energy absorption in the process of metal deformation, further reduce the impact force transmitted to the vehicle interior, and improve the safety of the door anti-collision beam;

[0029] By cooperating with the hat-shaped anti-collision beam 2 and the length adjustment component, the hat-shaped anti-collision beam 1 is placed between the two mounting seats, and the two hat-shaped anti-collision beams 2 are pulled to both sides respectively, and the ends of the two hat-shaped anti-collision beams 2 away from the hat-shaped anti-collision beam 1 can be quickly fixed under the cooperation of the clamping block and the clamping hole 1 on the hat-shaped anti-collision beam 2, so as to achieve the effect of quick installation, thereby achieving the effect of free adjustment of the spacing while quickly installing the hat-shaped anti-collision beam 2, so as to cope with the different installation spaces in the doors of different models, improve the applicability of the door anti-collision beam, and effectively improve the installation efficiency of the door anti-collision beam compared with traditional welding;

[0030] Through the cooperation of the hat-shaped anti-collision beam and the impact energy absorption component, when the vehicle door is subjected to external impact, the foam material first absorbs part of the impact force. When the external impact continues to be transmitted to the energy absorption plate, the energy absorption plate slides down to the hat-shaped anti-collision beam under the push of the external impact. When the energy absorbing teeth are broken by the impact, an energy absorption effect is generated to offset part of the external impact, and multiple energy absorption effects are achieved under the setting of multiple energy absorbing teeth, thereby improving the protection effect on passengers while also increasing the strength of the vehicle door anti-collision beam, thereby coping with the situation where the vehicle door anti-collision beam is easily damaged in mild collisions.

When the hat-shaped anti-collision beam 24 slides into the hat-shaped groove 501, the side of the hat-shaped anti-collision beam 24 away from the hat-shaped anti-collision beam 1 pushes the block 507, so that the block 507 retracts into the sliding cavity 505 and squeezes the spring 1 508 through the baffle 506. When the hat-shaped anti-collision beam 24 is adjusted After reaching the appropriate width, the block 507 pops out under the action of the spring 1 508 and is stuck into the card hole 1 509 and the card hole 2 510 corresponding to the current position of the hat-shaped anti-collision beam 2 4, so as to achieve the effect of quickly fixing the two hat-shaped anti-collision beams 2 4. Then the installer uses the hand to twist the rotating cylinder 610, and drives the nut 607 to rotate through the rotating cylinder 610, so that the nut 607 rotates the screw rod 608 out through the thread, so that the screw rod 608 moves the push rod 609 outward, so that the push rod 609 is pressed against the insertion rod 60 5, so that the insertion rod 605 is limited and locked, thereby limiting the sliding of the two hat-shaped anti-collision beams 4, and then the energy absorbing plate 702 is clamped in the limiting groove 705 of the hat-shaped anti-collision beam 1 through the limiting block 706, so that the installation of the door anti-collision beam can be completed, so that the hat-shaped anti-collision beam 4 can be quickly installed and the spacing can be freely adjusted at the same time, so as to cope with the different installation spaces in the doors of various models, improve the applicability of the door anti-collision beam, and effectively improve the installation efficiency of the door anti-collision beam compared with traditional welding.

[0057] Impact-absorbing components absorb impact forces:

[0058] When the vehicle door is subjected to external impact, the filling sleeve 707 closest to the outside of the vehicle door is hit first, and part of the impact force is absorbed by the foam material. When the external impact continues to be transmitted to the energy absorbing plate 702, the energy absorbing plate 702 slides toward the hat-shaped anti-collision beam 1 under the push of the external impact, so that the impact block 704 in the groove 703 contacts and collides with the energy absorbing tooth 701, and an energy absorption effect is generated when the energy absorbing tooth 701 is broken by the impact, offsetting part of the external impact, and achieving multiple energy absorption effects under the setting of multiple energy absorbing teeth 701, so that the vehicle door anti-collision beam can absorb energy multiple times before the external impact is transmitted to the hat-shaped anti-collision beam 1, thereby improving the protection effect on passengers while also increasing the strength of the vehicle door anti-collision beam, thereby coping with the situation that the vehicle door anti-collision beam is easily damaged in a mild collision.

[0059] The energy absorbing positioning component performs secondary energy absorption:

[0060] When the external impact is transmitted to the hat-shaped anti-collision beam 1, causing the hat-shaped anti-collision beam 1 to deform toward the inside of the vehicle, since the two hat-shaped anti-collision beams 24 and the two mounting seats 3 are fixedly connected by the clamping block 507 at this time, when the hat-shaped anti-collision beam 1 is deformed, the socket 612 will pull the insertion rod 605 that passes through the hat-shaped anti-collision beam 24. At this time, the insertion rod 605 is locked under the action of the screw rod 608, causing the socket 612 to deform and crack under the external impact and the pulling action of the insertion rod 605. Subsequently, the socket 612 away from the middle part of the hat-shaped anti-collision beam 1 continues to contact the insertion rod 605 and deform and crack, achieving a secondary energy absorption effect in the process of metal deformation, further reducing the impact force transmitted to the inside of the vehicle, and improving the safety of the door anti-collision beam.

[0061] Remove the slightly deformed door anti-collision beam for correction or replacement:

[0062] When the door anti-collision beam is slightly hit and only slightly bent, the rotating cylinder 610 is used to drive the nut 607 to rotate, so that the nut 607 drives the screw rod 608 to retract into the nut 607, thereby driving the push rod 609 to slide toward the nut 607. At this time, the push rod 609 no longer resists the insertion rod 605, and the two blocks 507 are pressed into the sliding cavity 505 in turn, so that the hat-shaped anti-collision beam 2 4 can be pulled toward the middle of the hat-shaped anti-collision beam 1, so that the hat-shaped anti-collision beam 1 and the hat-shaped anti-collision beam 2 4 can be taken out. If the hat-shaped anti-collision beam 1 and the hat-shaped anti-collision beam 2 4 are deformed to the point that they cannot be pulled, Press the clamping block 507 into the sliding cavity 505 so that the clamping block 507 is no longer clamped into the clamping hole 2 510, so that the hat-shaped cover plate 502 can be pulled in the direction of the hat-shaped anti-collision beam 1, so that the hat-shaped cover plate 502 slides out of the hat-shaped groove 501. At this time, the two hat-shaped anti-collision beams 2 4 lose their limit at one end away from the hat-shaped anti-collision beam 1, so that the hat-shaped anti-collision beam 1 and the hat-shaped anti-collision beam 2 4 can be directly taken out, avoiding the situation where the bolts are skewed when the door anti-collision beam is deformed, making it easy to take out and straighten the slightly deformed door anti-collision beam, or directly replace it.

[0063] Embodiment 2:

[0065] Step 1: First, cut the high-strength steel plate by a cutting machine;

[0066] Step 2: The cut high-strength steel is die-casted into a hat-shaped anti-collision beam 1, a sliding groove 2, a mounting seat 3, a hat-shaped cover plate 502, a hat-shaped anti-collision beam 2 4, and an energy absorption plate 702 respectively through a die-casting machine;

[0067] Step 3: Then, a hole punching machine is used to respectively punch a first clamping hole 509 and a second clamping hole 510 on the second hat-shaped anti-collision beam 4 and the hat-shaped cover plate 502;

[0068] Step 4: Install the filling sleeve 707 on the energy absorbing plate 702 and leave an injection port to inject the polyurethane foam material through a foaming machine;

[0069] Step 5: Then, the hat-shaped anti-collision beam 2 4 is assembled into the sliding groove 1 2 by a mechanical arm, and the energy absorption plate 702 and the hat-shaped anti-collision beam 1 are welded and assembled to each other;

[0070] Step 6: Then assemble the energy absorbing and positioning components on the two hat-shaped anti-collision beams 4.
