Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an automobile bumper bracket assembly. Background Art

[0002] The front bumper skeleton structure of a vehicle is also called the front anti-collision beam, which is usually located between the front bumper and the first crossbeam of the frame. It is the main force-bearing and force-transmitting component in a frontal collision. It is of great significance to the safety performance of the entire vehicle, especially the frontal collision performance. Currently known heavy-duty truck bumpers are of two types: one is made of metal material, usually steel plates are stamped into U-shaped channel steel, the surface is chrome-plated, and riveted or welded to the frame longitudinal beams. There is a large gap between the vehicle body and the vehicle body, as if it is an attached component, which is inconsistent with the body shape; the other is plastic, usually made of plastic or composite fiberglass material by injection molding, and assembled to the frame longitudinal beams through two connecting plates. It has decorative and aesthetic properties, but its anti-collision performance is poor. When the car is hit, not only the car itself is damaged, but the passengers are also subjected to huge impact force, and the safety of the driver and passengers cannot be effectively protected.

[0003] To this end, a heavy-duty truck front bumper skeleton assembly with announcement number "CN210258313U" includes an upper left tube beam, an upper right tube beam, an upper tube beam connecting plate, upper and lower tube beam fixing plates, a lower tube beam, upper and lower tube beam connecting reinforcement columns and a buffer rod. The upper left tube beam and the upper right tube beam are fixedly connected through the upper tube beam connecting plate, the bottom of the upper left tube beam and the upper right tube beam are welded with upper and lower tube beam fixing plates, the bottom of the upper and lower tube beam fixing plates are welded with the lower tube beam, the upper and lower tube beam connecting reinforcement columns are fixedly installed between the upper left tube beam and the lower tube beam, the upper and lower tube beam connecting reinforcement columns are fixedly installed between the upper right tube beam and the lower tube beam, the left headlight assembly is fixedly installed on the inner frame of the upper left tube beam, the right headlight assembly is fixedly installed on the inner frame of the upper right tube beam, the rear parts of the upper left tube beam, the upper right tube beam and the lower tube beam are all installed with buffer rods, and a spring is installed between the base and the top of the buffer rod. This device can provide a certain buffer for collision and improve driving safety.

[0004] However, for the above-mentioned heavy-duty truck front bumper frame assembly, although when a collision accident occurs, the impact force is partially absorbed by the bumper and the bumper frame body, and finally buffered by the buffer rod and the spring, so that the impact force is greatly reduced, the anti-collision performance is improved, and the driver and passengers are better protected, the following more obvious defects still exist during use: However, since the above-mentioned bumper assembly covers a small protection area on the front end of the truck, it is easy for the intercooler to be impacted and crushed into the cab in the event of a collision, and because the bumper frame provides less anti-collision protection for the middle part of the truck, the components are hit and cause harm to the driver. Utility Model Content

[0005] The purpose of the utility model is to provide an automobile bumper bracket assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile bumper bracket assembly, comprising two vertical beam brackets, and an upper cross beam bracket, a middle cross beam bracket, and a bottom beam bracket which are welded downwardly in sequence between the two vertical beams, both ends of the middle cross beam bracket and the bottom beam bracket are vertically welded with a central reinforcement vertical beam for strengthening the strength of the entire bumper bracket, a transverse reinforcement beam for protecting the intercooler is welded to the middle of the inner side of the central reinforcement vertical beam, and an inclined steel beam for strengthening the overall anti-collision strength of the transverse reinforcement beam is obliquely installed at the upper and lower ends of the transverse reinforcement beam, a buffer anti-collision beam which is arc-shaped and strengthens the anti-collision strength of the bumper bracket is provided between the surfaces of the central reinforcement vertical beam, and a hydraulic buffer is provided at the position of the inner side surface of the buffer anti-collision beam corresponding to the inclined steel beam.

[0007] Preferably, the upper and lower surfaces at both ends of the transverse reinforcement beam are provided with triangular reinforcement locking parts that are locked and fixed with bolts on the inner side of the central reinforcement vertical beam, so that the connection between the transverse reinforcement beam and the central reinforcement vertical beam is more secure, which can increase the overall strength of the truck bumper bracket.

[0008] Preferably, one end of the inclined steel beam is screwed to the side of the transverse reinforcement beam, and the other end of the inclined steel beam is fixed to the middle cross beam bracket and the bottom beam bracket respectively by screws, so that the transverse reinforcement beam has a strong anti-collision tensile force after being impacted, reducing damage to the internal components of the truck and further enhancing the anti-collision strength of the truck bumper bracket.

[0009] Preferably, the bottoms of the two vertical beam brackets are provided with side mounting supports extending obliquely outward, and bottom beam mounting supports extending downward are welded on both sides of the bottom side of the front end of the bottom beam bracket, so that the truck bumper bracket can be installed on the front of the truck cab through the side mounting supports and the bottom beam mounting supports, thereby achieving a good wrapping and anti-collision protection effect.

[0010] Preferably, buffer bags are respectively provided at both ends of the buffer anti-collision beam, and a mounting base is provided at the other end of the buffer bag. The mounting base is fixed on a centrally placed reinforcing vertical beam symmetrically arranged on a middle cross beam bracket and a bottom beam bracket, so that when the buffer anti-collision beam is hit, both ends of the buffer anti-collision beam have a certain buffering property and will not cause significant damage to the centrally placed reinforcing vertical beam.

[0011] Preferably, one end of the hydraulic buffer on the buffer anti-collision beam is sleeved with a spring part, and one end of the hydraulic buffer is fixed with a hydraulic top plate on the inner side of the inclined steel beam, which can effectively reduce the external impact force on the bumper bracket and reduce damage to the front of the truck.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the automobile bumper bracket assembly is realized by a central reinforcing vertical beam vertically symmetrically welded between the central cross beam bracket and the bottom beam bracket, a transverse reinforcing beam horizontally welded between the central reinforcing vertical beams, and an inclined steel beam obliquely symmetrically welded on the upper and lower surfaces of the transverse reinforcing beam, which is locked and connected to the inner sides of the central cross beam bracket and the bottom beam bracket. When the front bumper bracket of the truck is hit, the inclined steel beam is used to apply anti-collision pulling force to the transverse reinforcing beam, so that the impact force on the transverse reinforcing beam is effectively resolved and reduced. At the same time, when the inclined steel beam generates an impact pulling force on the transverse reinforcing beam, the central cross beam bracket and the bottom beam bracket connected to the other end of the inclined steel beam are used as stress support points to generate tensioning pulling force, so that the central reinforcing vertical beam can obtain an effective impact force buffering effect, thereby reducing the damage to the automobile intercooler caused by the impact force and causing personal injury in the cab.

[0013] Through the coordinated use of the buffer anti-collision beam, the top plate, the hydraulic buffer part, the buffer bag, the mounting base and the spring part arranged between the central reinforced vertical beams, when the truck is hit by an accident, the arc-shaped buffer anti-collision beam will first bear a certain impact force, and the buffer bags arranged at both ends of the buffer anti-collision beam will achieve the effect of buffering the outward pulling force and protecting it, thereby reducing the problem of tearing damage caused by the outward pulling force generated at the connection between the two ends of the buffer anti-collision beam and the central reinforced vertical beam after the impact, further ensuring the safety of the central reinforced vertical beam under impact and reducing the damage to the internal components of the truck caused by impact.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Please refer to Figure 1-2 , the present utility model provides a technical solution: an automobile bumper support assembly, including two vertical beam supports 1, and an upper cross beam support 2, a middle cross beam support 3, and a bottom cross beam support 4 that are horizontally and sequentially welded downward between the two vertical beams. Moreover, the two vertical beam supports 1, the upper cross beam support 2, the middle cross beam support 3, and the bottom cross beam support 4 are combined and welded into an automobile bumper support assembly. By means of welding, the strength between all connecting components of the bumper can be enhanced, and further the anti-collision strength of the bumper can be enhanced. Both ends of the middle cross beam support 3 and the bottom cross beam support 4 are vertically welded with middle-position reinforcing vertical beams 5 for enhancing the strength of the entire bumper support, which can increase the anti-collision strength of the middle cross beam support 3 and the bottom cross beam support 4. And the middle-position reinforcing vertical beams 5 are vertically and symmetrically welded in a square shape between the inner sides of the middle cross beam support 3 and the bottom cross beam support 4. A transverse reinforcing beam 6 for protecting the intercooler is welded in the middle of the inner side of the middle-position reinforcing vertical beam 5. The transverse reinforcing beam 6 is of a U-shaped structure, which is conducive to welding its two ends between the inner sides of the middle-position reinforcing vertical beams 5. Both the upper and lower ends of the transverse reinforcing beam 6 are obliquely installed with inclined steel beams 7 for enhancing the overall anti-collision strength of the transverse reinforcing beam 6, which can enable the transverse reinforcing beam 6 to have a certain anti-collision pulling force and endow the transverse reinforcing beam 6 with a certain anti-collision protection ability. A buffer anti-collision beam 8 that enhances the anti-collision strength of the bumper support and is arc-shaped is provided between the surfaces of the middle-position reinforcing vertical beams 5. And the buffer anti-collision beam 8 is in the shape of a sheet steel structure and has a certain elastic buffer force, which can effectively protect the transverse reinforcing beam 6. Hydraulic buffer parts 10 are provided at the positions corresponding to the inclined steel beams 7 on the inner side surface of the buffer anti-collision beam 8, which can enable the bumper support to have the effect of multiple anti-collision buffers and reduce the damage degree of the bumper support assembly.

[0019] Triangular reinforcing locking parts 11 that are bolt-locked and fixed to the inner side of the middle-position reinforcing vertical beam 5 are provided on the upper and lower surfaces at both ends of the transverse reinforcing beam 6. And one end of the triangular reinforcing locking part 11 is welded to the side surfaces at both ends of the transverse reinforcing beam 6, and the other side of the inverted triangular reinforcing locking part 11 is locked to the inner side of the middle-position reinforcing vertical beam 5 by screws, which can further enhance the rigidity of the transverse reinforcing beam 6. One end of the inclined steel beam 7 is locked to the side surface of the transverse reinforcing beam 6 by screws, and the other ends of the inclined steel beam 7 are respectively fixed to the middle cross beam support 3 and the bottom cross beam support 4 by screws, which can be welded to form a bumper support assembly with higher anti-collision strength and improve the anti-collision protection effect for the driver. Slant-side mounting supports 12 that extend obliquely outward are provided at the bottoms of the two vertical beam supports 1, and bottom cross beam mounting supports 13 that extend downward are welded to both sides of the front bottom of the bottom cross beam support 4, so as to realize the anti-collision protection function of the automobile bumper support assembly when it is installed at the front of the truck.

[0020] The two ends of the buffer anti-collision beam 8 are respectively provided with a buffer bag 14, and the other end of the buffer bag 14 is provided with a mounting base 15, which is used to weld the buffer bag 15 to the surface of the central reinforced vertical beam 5, and a headlight mounting position for installing the car headlight is formed between the central reinforced vertical beam 5 and the vertical beam bracket 1. The mounting base 15 is fixed on the central reinforced vertical beam 5 symmetrically arranged on the middle cross beam bracket 3 and the bottom beam bracket 4, so as to reduce the pulling force on the central reinforced vertical beam 5 after the bumper is hit. One end of the hydraulic buffer 10 on the buffer anti-collision beam 8 is sleeved with a spring member 16, and one end of the hydraulic buffer 10 is fixed with a top plate 9 hydraulically supported on the inner side of the inclined steel beam 7, so that the reinforced buffer anti-collision beam 8 has an effective buffering and anti-collision effect, and further enhances the overall anti-collision strength of the bumper bracket assembly.

[0021] Specifically, when in use, the automobile bumper bracket assembly is first fixed to the installation position of the front of the truck through the side mounting bracket 12 and the bottom beam mounting bracket 13, and the upper end of the automobile bumper bracket assembly is installed at the reserved position in the front of the truck through the upper cross beam bracket 2. When the automobile bumper bracket assembly is hit, after the arc-shaped structure buffer anti-collision beam 8 is hit, the two ends of the buffer anti-collision beam 8 generate an outward impact pulling force, so that the buffer bag 14 is stretched outward to buffer and reduce the impact pulling force generated by the two ends of the buffer anti-collision beam 8 on the centrally arranged reinforcing vertical beam 5, and the hydraulic buffer 10 and the top plate 9 are supported by the buffering compression when the force is applied. On the surface of the inclined steel beam 7, the impact force generated can be hydraulically buffered and reduced, so that the impact force on the transverse reinforcement beam 6 can be reduced, and the inclined steel beam 7 is used to apply anti-collision pulling force to the transverse reinforcement beam 6, so that the impact force on the transverse reinforcement beam 6 can be effectively resolved and reduced. At the same time, when the inclined steel beam 7 generates an impact pulling force on the transverse reinforcement beam 6, the middle cross beam bracket 3 and the bottom beam bracket 4 connected to the other end of the inclined steel beam 7 are used as stress support points to generate tension pulling force, which can make the central reinforcement vertical beam 5 obtain the effect of effective impact force buffering, thereby reducing the damage of the impact force to the car intercooler and causing personal injury in the cab.
