Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a novel anti-collision beam for a vehicle door. Background Art

[0002] In a mild side collision accident, the car door and the door anti-collision beam will only produce slight deformation and still have certain use value. At this time, the car door and the door anti-collision beam can be straightened through sheet metal. After straightening, the protective strength of the car 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 useful is difficult to remove and needs to be removed and replaced by cutting, etc., 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 need to be used. This is not only troublesome during manufacturing, but also adds the step of selecting the door anti-collision beam according to size during installation, which has a certain impact on the installation efficiency of the door anti-collision beam.

[0026] As described above, the features and advantages of the novel door anti-collision beam and the manufacturing method thereof in the present invention are:

[0027] By cooperating with 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 stuck 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 are no longer limited, so that the cap-shaped anti-collision beams 1 and 2 can be directly removed, avoiding the situation where the screw rod is skewed when the door anti-collision beam is deformed, making it difficult to remove the door anti-collision beam, and facilitating the removal and straightening of the slightly deformed door anti-collision beam, or directly replacing it;

[0028] When the first hat-shaped anti-collision beam is deformed toward the interior of the vehicle, the two second hat-shaped anti-collision beams are fixedly connected to the two mounting seats by the clamping blocks. Therefore, when the first hat-shaped anti-collision beam is deformed, the plug hole will pull the plug rod passing through the second hat-shaped anti-collision beam. At this time, the plug rod is 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. Then, the plug hole away from the middle of the first hat-shaped anti-collision beam continuously contacts the plug rod and deforms and cracks, achieving a secondary energy absorption effect in the process of metal deformation, further reducing the impact force transmitted to the interior of the vehicle, and improving the safety of the door anti-collision beam.

[0029] By cooperating with the second hat-shaped anti-collision beam and the length adjustment component, the first hat-shaped anti-collision beam is placed between the two mounting seats, and the two second hat-shaped anti-collision beams are pulled to both sides respectively. Then, the two second hat-shaped anti-collision beams can be quickly fixed at one end away from the first hat-shaped anti-collision beam under the cooperation of the clamping block and the clamping hole 1 on the second hat-shaped anti-collision beam, thereby achieving a quick installation effect. Thus, while the second hat-shaped anti-collision beam is quickly installed, the spacing can be freely adjusted to cope with the different installation spaces in the doors of different models, thereby improving the applicability of the door anti-collision beam and effectively improving the installation efficiency of the door anti-collision beam compared to 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 toward 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, which offsets part of the external impact, and achieves multiple energy absorption effects under the setting of multiple energy absorbing teeth. While improving the protection effect on passengers, it also increases 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 mild collisions.

[0051] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0052] The initial state is:

[0053] The mounting seat 3 is not installed, the limit block 504 is located in the limit groove 503, so that the hat-shaped cover plate 502 blocks the hat-shaped groove 501, the spring 508 is extended, so that the baffle 506 is located on the side of the sliding cavity 505 close to the block 507, the nut 607 is not rotated, the screw rod 608 is located in the nut 607, so that the top of the push rod 609 is flush with the fixed plate 604, the spring 2 606 is extended, so that the insertion rod 605 extends out of the cylinder 601, and the four insertion rods 605 are respectively stuck in the four insertion holes 612 closest to the middle of the hat-shaped anti-collision beam 1, so that the two hat-shaped anti-collision beams 2 4 conflict with each other, the energy absorption plate 702 is not installed on the hat-shaped anti-collision beam 1, and the impact block 704 conflicts with the energy absorption tooth 701 closest to the energy absorption plate 702.

[0054] The working status is:

[0055] Install the door impact beam into the door:

[0056] During installation, first install the two mounting seats 3 to the mounting holes reserved in the vehicle door through bolts, then place the hat-shaped anti-collision beam 1 between the two mounting seats 3, and pull the two hat-shaped anti-collision beams 2 4 to both sides respectively. When the hat-shaped anti-collision beam 2 4 slides toward both sides of the hat-shaped anti-collision beam 1, the insertion rod 605 continuously slides into the cylinder 601 under the action of the card engagement with the insertion hole 612, so that the insertion rod 605 squeezes the spring 2 606 and continuously pops out under the extension action of the spring 2 606. When the two hat-shaped anti-collision beams 2 4 are away from the hat-shaped anti-collision beam One end of the collision beam 1 slides into the two hat-shaped grooves 501 respectively, and the insertion rod 605 is inserted into the insertion hole 612 corresponding to the current position of the two hat-shaped anti-collision beams 24, achieving the effect of auxiliary fixation, which is convenient for the installation of the hat-shaped anti-collision beam 1 and the hat-shaped anti-collision beam 24. When the hat-shaped anti-collision beam 24 slides into the hat-shaped groove 501, the hat-shaped anti-collision beam 24 pushes the block 507 away from the side of the hat-shaped anti-collision beam 1, 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 in 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 quickly fix the two hat-shaped anti-collision beams 2 4. Then the installer uses the hand to twist the rotating cylinder 610, and the rotating cylinder 610 drives the nut 607 to rotate, so that the nut 607 rotates the screw rod 608 out through the thread, so that the screw rod 608 moves 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 2 4, and then the energy absorbing plate 702 is clamped in the limiting groove 2 705 of the hat-shaped anti-collision beam 1 through the limiting block 2 706, and the installation of the door anti-collision beam can be completed, so that the spacing can be freely adjusted while the hat-shaped anti-collision beam 2 4 is quickly installed, 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 to traditional welding.

[0057] Impact-absorbing components absorb impact forces:

[0058] When the vehicle door is subjected to an 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. When the energy absorbing tooth 701 is broken by the impact, an energy absorption effect is generated, which offsets part of the external impact, and achieves multiple energy absorption effects under the setting of multiple energy absorbing teeth 701, so that the vehicle door anti-collision beam absorbs 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 mild collisions.

[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 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 presses against the insertion rod 605, and the two blocks 507 are pressed into the sliding cavity 505 in turn, and 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 in the clamping hole 2 510, so that the hat-shaped cover plate 502 can be pulled toward 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 are no longer limited 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 door anti-collision beam is deformed and the bolts are skewed, making it difficult to remove the door anti-collision beam, and facilitating the removal and straightening of the slightly deformed door anti-collision beam, or directly replacing it.

[0065] Step 1: First, cut the high-strength steel plate through 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 in 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 the foaming machine;

[0069] Step 5: Then, the second hat-shaped anti-collision beam 4 is assembled into the sliding groove 1 2 by a robotic 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.
