Description

Technical Field

[0001] This utility model relates to a front bumper beam structure for automobiles, specifically a composite material front bumper beam assembly structure for automobiles, belonging to the technical field of front bumper beams for automobiles. Background Technology

[0002] The front bumper beam is a crucial safety component in the front structure of a vehicle. Typically installed at the front of the vehicle, it absorbs and disperses collision energy during frontal or offset collisions, thereby protecting the integrity of the passenger compartment and reducing the risk of occupant injury. The front bumper beam assembly usually consists of a crossbeam, an energy-absorbing box, and brackets or mounting plates that connect to the vehicle body. The crossbeam is the primary load-bearing component, while the energy-absorbing box undergoes plastic deformation during a collision to absorb collision energy. Composite materials in automotive composite front bumper beams refer to novel materials composed of two or more materials with different physical and chemical properties, typically consisting of a matrix material and reinforcing materials. This material design aims to achieve comprehensive performance that cannot be achieved by a single material through the synergistic effect of different components.

[0003] However, current automotive front bumper beam assemblies typically consist of a front bumper beam body made of composite materials and an energy-absorbing box. Some also have a foam baffle fastened to the outside of the front bumper beam. In the event of an accident, the foam baffle impacts first to cushion the impact force. The front bumper beam and the foam baffle are only connected by a locking post and a locking hole. When a car collides, the foam baffle can easily be pushed out directly, and the locking post on the foam baffle separates from the locking hole on the bumper beam. The foam baffle provides poor protection for the front bumper beam, and after being pushed out, it can easily get stuck on other parts, causing damage to those parts. Utility Model Content

[0004] The purpose of this utility model is to provide a composite material front bumper beam assembly structure for automobiles in order to solve the above problems. By fitting a foam board on the outside of the front bumper beam and positioning the foam board with an energy-absorbing box, the foam board is securely connected to the front bumper beam. This ensures that the front bumper beam is buffered and protected when the vehicle collides, and prevents the foam board from being pushed out and causing other parts to be crushed and damaged.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a composite material front bumper beam assembly structure for automobiles, comprising a front bumper beam and a protective mechanism, a buffer mechanism, and an installation mechanism mounted on the front bumper beam. The protective mechanism includes a housing, on which the front bumper beam is fitted. The housing has two opposing limiting grooves. The sidewall of the housing is provided with a foam board. The front bumper beam is equipped with a buffer mechanism, which includes energy-absorbing boxes. Two energy-absorbing boxes are inserted into the front bumper beam, and the two energy-absorbing boxes are respectively engaged inside the two limiting grooves. Mounting holes are provided at the top and bottom of the energy-absorbing boxes and at the top and bottom of the front bumper beam. The energy-absorbing boxes are fixedly connected to the front bumper beam through bolts and mounting holes.

[0006] Preferably, the front bumper beam has an arc-shaped structure, and the cross-section of the front bumper beam has a square-shaped structure.

[0007] Preferably, the thickness of the energy-absorbing box is equal to the thickness of the shell, and the end of the energy-absorbing box has a U-shaped structure.

[0008] Preferably, the buffer mechanism further includes an induction groove, and both sides of the two energy-absorbing boxes are provided with an induction groove, and the induction groove has a wave-shaped structure.

[0009] Preferably, the front anti-collision beam has internal reinforcing ribs, the middle section of which is an isosceles trapezoidal structure, and the top and bottom of the reinforcing ribs are provided with mounting holes, and the bolt is threadedly connected to the mounting holes on the reinforcing ribs.

[0010] Preferably, the length of the casing is equal to the length of the front bumper beam, and the thickness of the casing is equal to the thickness of the foam board.

[0011] Preferably, the installation mechanism includes an installation plate, and the ends of both energy-absorbing boxes are fixedly connected to the installation plate, with four bolts inserted into each of the two installation plates in a rectangular shape.

[0012] Preferably, the mounting mechanism further includes a hanging plate, and the side walls of the two mounting plates are fixedly connected to the hanging plate at an angle.

[0013] Preferably, the front bumper beam is provided with a leveling mechanism at both ends. The leveling mechanism includes a rotating shaft. Two rotating shafts are fixedly connected to the center of both ends of the front bumper beam. A baffle is rotatably connected to each of the two rotating shafts. The length of the baffle is less than the distance between the rotating shaft and the side of the foam board.

[0014] The beneficial effects of this utility model are as follows: the casing is placed on the outside of the front bumper beam, and the two energy-absorbing boxes are respectively inserted into the front bumper beam and engaged with the inner sides of the two limiting grooves opened opposite each other on the casing. This achieves the initial fixation of the energy-absorbing boxes to the casing. The energy-absorbing boxes, casing and front bumper beam are fixed together by bolts, completing the installation of the foam board. This ensures that the foam board is firmly connected to the front bumper beam, ensuring that the front bumper beam is buffered and protected when the vehicle is involved in a collision, and preventing the foam board from being pushed out and causing other parts to be squeezed and damaged.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6As shown, a composite material front bumper beam assembly structure for automobiles includes a front bumper beam 1 and a protective mechanism 2, a buffer mechanism 3, and a mounting mechanism 4 installed on the front bumper beam 1. The protective mechanism 2 includes a housing 201, which is fitted onto the front bumper beam 1 (the housing is made of basalt fiber composite material). Two limiting grooves 203 are opened opposite each other on the housing 201. Foam board 202 is provided on the side wall of the housing 201. The buffer mechanism 3 is installed on the front bumper beam 1. The buffer mechanism 3 includes an energy-absorbing box 301, which is inserted into the front bumper beam 1. The two energy-absorbing boxes 301 are respectively engaged inside the two limiting grooves 203. Mounting holes 304 are opened at the top and bottom of the energy-absorbing boxes 301 and at the top and bottom of the front bumper beam 1. The energy-absorbing boxes 301 are fixedly connected to the front bumper beam 1 by bolts 302 and mounting holes 304.

[0024] As a technical optimization of this utility model, the front anti-collision beam 1 has an arc-shaped structure, and the cross-section of the front anti-collision beam 1 has a U-shaped structure, which facilitates the installation of the reinforcing rib 5.

[0025] As a technical optimization of this utility model, the thickness of the energy-absorbing box 301 is equal to the thickness of the shell 201, and the end of the energy-absorbing box 301 has a U-shaped structure, which increases the flatness of the shell 201 and the energy-absorbing box 301 and improves the protective performance of the front anti-collision beam 1.

[0026] As a technical optimization of this utility model, the buffer mechanism 3 also includes an induction groove 303. Both sides of the two energy-absorbing boxes 301 are provided with an induction groove 303, and the induction groove 303 has a wave-shaped structure, which facilitates the stepped deformation of the energy-absorbing box 301 and avoids damage to automotive parts.

[0027] As a technical optimization of this utility model, the front anti-collision beam 1 is provided with a reinforcing rib 5 inside. The middle section of the reinforcing rib 5 is an isosceles trapezoidal structure, and the top and bottom of the reinforcing rib 5 are provided with mounting holes 304. The bolt 302 is threadedly connected to the mounting holes 304 on the reinforcing rib 5 to increase the stability of the front anti-collision beam 1 structure.

[0028] As a technical optimization of this utility model, the length of the sleeve 201 is equal to the length of the front bumper beam 1, and the thickness of the sleeve 201 is equal to the thickness of the foam board 202, so as to achieve comprehensive protection for the front bumper beam 1.

[0029] As a technical optimization of this utility model, the installation mechanism 4 includes an installation plate 401. The ends of the two energy-absorbing boxes 301 are fixedly connected to the installation plate 401. Four bolts 402 are inserted into the two installation plates 401 in a rectangular shape, so as to install the overall structure onto the frame.

[0030] As a technical optimization of this utility model, the installation mechanism 4 also includes a hanging plate 403. The side walls of the two mounting plates 401 are inclined and fixedly connected with the hanging plate 403, which makes it convenient to suspend the entire structure on the vehicle body through the hanging plate 403 when installing the overall structure, and makes it convenient for the assembly personnel to install the screws.

[0031] As a technical optimization of this utility model, the front anti-collision beam 1 is provided with a leveling mechanism 6 at both ends. The leveling mechanism 6 includes a rotating shaft 601. Two rotating shafts 601 are fixedly connected to the center of both ends of the front anti-collision beam 1. A baffle 602 is rotatably connected to each of the two rotating shafts 601. The length of the baffle 602 is less than the distance between the rotating shaft 601 and the side of the foam board 202, so that after the shell 201 is installed, the baffle 602 can be used to make the shell 201 flush with the end of the front anti-collision beam 1, which facilitates the installation of the energy absorption box 301.

[0032] In use, the reinforcing rib 5 is first placed inside the front bumper beam 1, and can be inserted from one end of the front bumper beam 1. Since the front bumper beam 1 has an arc-shaped structure and a U-shaped cross-section, it is easy to install the reinforcing rib 5. The middle section of the reinforcing rib 5 has an isosceles trapezoidal structure, and there are mounting holes 304 at the top and bottom. A bolt 302 is used to pass through the mounting holes 304 to firmly connect the reinforcing rib 5 to the front bumper beam 1, thereby increasing the stability of the front bumper beam 1 structure. The sleeve 201 is then fitted onto the front bumper beam 1, ensuring that the length of the sleeve 201 is equal to the length of the front bumper beam 1, so as to achieve full protection for the front bumper beam 1. When fitting the sleeve 201, the baffle 602 should be rotated to the inside of the front bumper beam 1 and tilted at a 45-degree angle to avoid obstructing the insertion of the sleeve 201. A foam board 202 is provided on the side wall of the sleeve 201, and the thickness of the sleeve 201 is consistent with the thickness of the foam board 202, which increases the stability of the structure. At this point, rotate the baffles 602 connected to the shafts 601 at both ends of the front bumper beam 1 to a horizontal position. Since the length of the baffles 602 is less than the distance between the shafts 601 and the side of the foam board 202, the baffles 602 can be used to measure whether the end of the housing 201 is flush with the end of the front bumper beam 1, thus preparing for the subsequent installation of the energy-absorbing boxes 301. Insert the two energy-absorbing boxes 301 into the front bumper beam 1 respectively, and make them engage with the two limiting grooves opened opposite each other on the housing 201. Inside 203, the energy-absorbing box 301 is initially fixed to the shell 201. The thickness of the energy-absorbing box 301 is equal to the thickness of the shell 201, and its ends have a U-shaped structure. This increases the flatness of the shell 201 and the energy-absorbing box 301, improves the protective performance of the front bumper beam 1, ensures that the foam board 202 is firmly connected to the front bumper beam 1, and ensures that the front bumper beam 1 is buffered and protected when the vehicle collides, preventing the foam board 202 from being pushed out and causing other parts to be damaged. The component was damaged by compression. Mounting holes 304 are provided on the top and bottom of the energy-absorbing box 301 and the top and bottom of the front anti-collision beam 1. Bolts 302 are used to pass through these mounting holes 304 to fix the energy-absorbing box 301 to the front anti-collision beam 1. At the same time, the energy-absorbing box 301 has a wave-shaped guide groove 303 on both sides. This design facilitates the stepped deformation of the energy-absorbing box 301 when it is impacted, avoiding damage to other parts of the car. Finally, mounting plates 401 are fixedly connected to the ends of the two energy-absorbing boxes 301. Four bolts 402 are inserted into each mounting plate 401 in a rectangular shape. In addition, hanging plates 403 are fixedly connected to the side walls of the two mounting plates 401 at an angle. When installing the whole structure onto the frame, the whole structure can be suspended in a suitable position on the vehicle body through the hanging plates 403 to facilitate the installation of bolts 402 by the assembly personnel. Finally, the bolts 402 are tightened with tools to securely install the whole structure onto the frame.
