Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to an anti-collision beam for an automobile door. Background Art
[0002] The anti-collision beam is a structure used to withstand the impact force on the car. It is a passive safety device of the car and is mainly installed on the door, front and rear of the car. Its principle is to absorb part of the impact force and distribute part of the impact force to the frame, thereby reducing the damage caused by the collision to the vehicle. It is an indispensable part of car safety.
[0003] Existing door anti-collision beams are usually steel pipes or steel plates that are stamped and bent. They are the main structure to bear the impact force. Relying on their own deformation to absorb and consume the impact force can easily cause the anti-collision beam to deform too much, making it difficult to repair and can only be replaced. If it is forcibly repaired, its strength will be reduced due to stress and metal fatigue, and it will be easy to break when used next time. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide an automobile door anti-collision beam to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile door anti-collision beam, comprising a mounting plate, beam plates are connected to both sides of the top of the mounting plate, and slide grooves are opened on both sides of the top of the beam plate, bolts are arranged inside the slide grooves, the top of the beam plate is connected to a high-toughness plate through a filling plate, the bottom of the high-toughness plate is connected to a screw, and a nut is sleeved on the outside of the screw.
[0006] By adopting the above technical solution, when a collision occurs, the high-toughness plate is bent and deformed by force to absorb the impact force, and at the same time the filling plate is compressed and deformed by force to buffer the impact force, and the filling plate prevents the high-toughness plate from colliding with the beam plate, and the beam plate is also bent and deformed by force to absorb the impact force. By installing the plate, beam plate, high-toughness plate and filling plate to form a three-layer deformation energy absorption structure and a single-layer support structure, the three-layer structure deforms together to absorb the impact force, thereby preventing most of the impact force from being borne by the beam plate.
[0007] Furthermore, the slide groove is slidably connected to the bolt, and the cross-section of the beam plate is in an "M" shape.
[0008] By adopting the above technical solution, when the beam plate bends and deforms to absorb impact force, the slide groove will slide on the surface of the bolt, causing the two sides of the beam plate to slide and displace in both directions, thereby preventing the two sides of the beam plate from being fixed, resulting in the beam plate only being able to bend and squeeze downward to absorb impact force, reducing the deformation of the beam plate and avoiding excessive deformation.
[0009] Furthermore, the filling plate is made of rubber, the high-toughness plate is made of carbon fiber or glass fiber, and the mounting plate and beam plate are made of high-strength steel.
[0010] By adopting the above technical solution, when a collision occurs, the high-toughness plate is subjected to force and bends to deform, thereby absorbing the impact force, while the filling plate is subjected to force and compression to deform to buffer the impact force, and the filling plate prevents the high-toughness plate from colliding with the beam plate, and the beam plate is also subjected to force and bends to deform to absorb the impact force.
[0011] Furthermore, the high-toughness plate is detachably connected to the beam plate via screws and nuts, and the beam plate is detachably connected to the mounting plate via bolts.
[0012] By adopting the above technical solution, when a certain layer of the structure is damaged, the staff can easily dismantle and replace the beams and plates separately through bolts, and easily replace the filling plates and high-toughness plates separately through screws and nuts. The structures can be replaced separately, so only the damaged structure needs to be replaced.
[0013] Furthermore, a mounting hole is opened on the top of the mounting plate, and a plurality of mounting holes are provided, and the plurality of mounting holes are symmetrically distributed.
[0014] By adopting the above technical solution, during assembly, the staff connects the mounting hole to the vehicle door through structures such as rivets or bolts, thereby completing the assembly of the entire anti-collision beam.
[0015] Furthermore, a sleeve is connected to the bottom of the high-toughness plate, and a rib is connected to the outer surface of the sleeve.
[0016] By adopting the above technical solution, due to the setting of the sleeve, the fixing area of the screw is increased, and the setting of the rib plate increases the connection strength between the sleeve and the high-toughness plate, thereby preventing the bending deformation of the middle area of the high-toughness plate from causing the screw and the glue fixing surface to tear and fall off.
[0017] Furthermore, a protrusion is arranged in the middle of the top of the high-toughness board.
[0018] By adopting the above technical solution, the middle bulge on the top of the high-toughness board increases the thickness, thereby preventing the high-toughness board from bending and deforming in the middle area, causing the screw and glue fixing surface to tear and fall off.
[0019] Furthermore, the high-toughness plate, screw rod, sleeve and rib plate are fixedly connected by strong glue, and a plurality of rib plates are provided, and the plurality of rib plates are distributed in a ring array.
[0020] By adopting the above technical solution, the high-toughness plate, screw, sleeve and rib are bonded together by glue, so as to facilitate processing and avoid the high cost of integral molding of the high-toughness plate, screw, sleeve and rib.
[0021] In summary, the utility model mainly has the following beneficial effects:
[0022] 1. The utility model is provided with the installation plate, beam plate, high-toughness plate and filling plate. When impact occurs, the high-toughness plate is bent and deformed by force to absorb the impact force. At the same time, the filling plate is compressed and deformed by force to buffer the impact force. The filling plate prevents the high-toughness plate from colliding with the beam plate. The beam plate is also bent and deformed by force to absorb the impact force. The installation plate, beam plate, high-toughness plate and filling plate form a three-layer deformation energy absorption structure and a single-layer support structure. The three-layer structure deforms together to absorb the impact force, avoiding that most of the impact force is borne by the beam plate; effectively reducing the phenomenon that the anti-collision beam is difficult to repair due to excessive deformation, and extending the service life of the anti-collision beam;
[0023] 2. The utility model connects the beam plate to the mounting plate through the setting of the slide groove and the bolt, so as to prevent the beam plate from falling off the mounting plate. When the beam plate bends and deforms to absorb the impact force, the slide groove will slide on the surface of the bolt, so that the two sides of the beam plate slide and displace in both directions, so as to prevent the two sides of the beam plate from being fixed and causing the beam plate to bend downward and squeeze to absorb the impact force, thereby reducing the deformation of the beam plate and preventing the deformation from being too large; and increasing the service life of the beam plate;
[0024] 3. The utility model uses bolts, screws and nuts to facilitate the separate disassembly and replacement of beams and plates, and the separate replacement of filling plates and high-toughness plates through screws and nuts. The structures can be replaced separately, so only the damaged structure needs to be replaced, thereby reducing replacement costs. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The following describes an embodiment of the utility model based on its overall structure.
[0032] Embodiment 1:
[0033] A car door anti-collision beam, such as Figure 1-Figure 4 As shown, it includes a mounting plate 1, and beam plates 3 are connected to both sides of the top of the mounting plate 1. The mounting plate 1 and the beam plates 3 are made of high-strength steel. The cross-section of the beam plates 3 is in the shape of an "M". Slide grooves 4 are provided on both sides of the top of the beam plates 3. Bolts 5 are arranged inside the slide grooves 4. The slide grooves 4 are slidably connected with the bolts 5. When the beam plates 3 are bent and deformed to absorb impact force, the slide grooves 4 will slide on the surfaces of the bolts 5, so that the two sides of the beam plates 3 slide and displace in both directions, so as to avoid that the two sides of the beam plates 3 are fixed so that the beam plates 3 can only bend downward to squeeze and absorb impact force, thereby reducing the deformation of the beam plates 3 and avoiding excessive deformation. The beam plates 3 are detachably connected to the mounting plate 1 by the bolts 5. The bolts 5 are used to facilitate the separate disassembly and replacement of the beam-slab 3; the top of the beam-slab 3 is connected to the high-toughness plate 7 through the filling plate 6, the filling plate 6 is made of rubber, and the high-toughness plate 7 is made of carbon fiber or glass fiber. The high-toughness plate 7 is bent and deformed under stress to absorb the impact force, and the filling plate 6 is compressed and deformed under stress to buffer the impact force, and the filling plate 6 prevents the high-toughness plate 7 from colliding with the beam-slab 3; the bottom of the high-toughness plate 7 is connected to a screw rod 8, and a nut 9 is sleeved on the outside of the screw 8. The high-toughness plate 7 is detachably connected to the beam-slab 3 through the screw 8 and the nut 9, and the filling plate 6 and the high-toughness plate 7 can be easily replaced separately through the screw 8 and the nut 9.
[0034] See also Figure 1-Figure 4 In the above embodiment, a mounting hole 2 is opened on the top of the mounting plate 1, and a plurality of mounting holes 2 are provided, and the plurality of mounting holes 2 are symmetrically distributed. During assembly, the staff connects the mounting hole 2 to the vehicle door through structures such as rivets or bolts, thereby completing the assembly of the entire anti-collision beam.
[0035] Embodiment 2:
[0036] On the basis of the above-mentioned embodiment 1, in order to avoid high cost of structural replacement, a split structure is used to facilitate individual replacement.
[0037] See also Figure 1-Figure 4 In the above embodiment, a sleeve 10 is connected to the bottom of the high-toughness plate 7, a rib 11 is connected to the outer surface of the sleeve 10, a protrusion is arranged in the middle of the top of the high-toughness plate 7, the high-toughness plate 7, the screw 8, the sleeve 10 and the rib 11 are fixedly connected by strong glue, a plurality of ribs 11 are arranged, and the plurality of ribs 11 are distributed in a ring array. Due to the arrangement of the sleeve 10, the fixing area of the screw 8 is increased, and the arrangement of the rib 11 increases the connection strength between the sleeve 10 and the high-toughness plate 7, and the thickness of the protrusion in the middle of the top of the high-toughness plate 7 is increased, thereby preventing the high-toughness plate 7 from bending and deforming in the middle area, causing the screw 8 and the glue fixing surface to tear and fall off.
[0038] The implementation principle of the utility model is as follows: first, the beam plate 3 is connected to the mounting plate 1 by bolts 5 to prevent the beam plate 3 from falling off the mounting plate 1, and the high-toughness plate 7 is connected to the beam plate 3 by screws 8 and nuts 9, and the filling plate 6 is clamped by the high-toughness plate 7 and the beam plate 3, thereby preventing the high-toughness plate 7 and the filling plate 6 from falling off. Due to the setting of the sleeve 10, the fixing area of the screw 8 is increased, and the setting of the rib plate 11 increases the connection strength between the sleeve 10 and the high-toughness plate 7, and the middle bulge on the top of the high-toughness plate 7 increases the thickness, thereby preventing the high-toughness plate 7 from bending and deforming in the middle area, causing the screw 8 and the glue fixing surface to tear and fall off. During assembly, the staff connects the mounting hole 2 to the car door through structures such as rivets or bolts, thereby completing the assembly of the entire anti-collision beam;

When the beam plate 3 is bent and deformed to absorb the impact force, the slide groove 4 will slide on the surface of the bolt 5, so that the two sides of the beam plate 3 slide and displace in both directions, avoiding that the two sides of the beam plate 3 are fixed so that the beam plate 3 can only bend downward to squeeze and absorb the impact force, reducing the deformation of the beam plate 3 to avoid excessive deformation. The three-layer deformation energy absorption structure and the single-layer support structure are formed by installing the plate 1, the beam plate 3, the high-toughness plate 7 and the filling plate 6. The three-layer structure deforms together to absorb the impact force, avoiding that most of the impact force is borne by the beam plate 3;
[0040] When a layer of the structure is damaged, the staff can easily dismantle and replace the beam plate 3 separately through the bolt 5, and easily replace the filling plate 6 and the high-toughness plate 7 separately through the screw rod 8 and the nut 9. The structure can be replaced separately, so only the damaged structure needs to be replaced.
