Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a front bumper beam assembly and an automobile. Background Technology

[0002] Existing crash beams are devices used to absorb collision energy when a vehicle is involved in a collision. They mainly consist of a main beam, an energy-absorbing box, and a mounting plate that connects to the car. Both the main beam and the energy-absorbing box can deform and absorb energy during a low-speed collision, thereby effectively absorbing the collision energy and minimizing the damage to the longitudinal beams of the vehicle body.

[0003] Currently, with the further development of automotive technology, the usage requirements for front bumper beams are no longer limited to protection, but also include the problem of obstructing ventilation. For example, in electric vehicles, the cooling module is usually located behind the front bumper beam. In some cases, the front bumper beam and the car's air intake grille have a partially or completely overlapping structural design, which will have an adverse effect on the ventilation of the car's cooling module.

[0004] In recent years, with the further development of related technologies, some technical solutions have begun to emerge in the existing technology for the auxiliary ventilation problem during the use of automotive front bumper beams. For example, the patent document with application number 201921763405.5 discloses a technical solution that "a ventilation component is set between the front cover and the beam body. The ventilation component can not only reduce the shielding effect of the automotive front bumper beam assembly on the cooling module, but also increase its ventilation volume, thereby improving the heat dissipation performance of the automotive cooling module." However, this technical means of directly opening multiple holes at the front end of the front bumper beam, although meeting the ventilation requirements, also sacrifices some of the structural strength of the front bumper beam. Secondly, the automotive operating environment is complex. When facing some dusty environments, if the air used for cooling is not filtered, a large amount of dust will accumulate inside the front compartment of the car, affecting the stable use of other automotive components. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a front anti-collision beam assembly for automobiles and an automobile, which solves the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a front bumper beam assembly and a car, including a front bumper beam body and energy-absorbing boxes installed on both sides of the rear end of the front bumper beam body. The front bumper beam body is internally fitted with a reinforcing plate, and the inner wall of the reinforcing plate is provided with a clearance groove. A first dust filter is nested in the clearance groove, and a filtration space is formed between the first dust filter, the reinforcing plate, and the front inner wall of the front bumper beam body. The bottom of the front bumper beam body is provided with an air intake groove that communicates with the transition space.

[0007] The rear end space of the front anti-collision beam body is connected to the filter space, and the rear end structure of the front anti-collision beam body has an air outlet groove that is connected to its own rear end space.

[0008] Specifically, the air intake slot is internally fitted with a reinforcing duct, the top of which is fixedly connected to the top inner wall of the front bumper beam body. The reinforcing duct enhances the structural strength of the air intake slot and the area near the air intake slot.

[0009] Specifically, the inner walls of the front and rear ends of the reinforced duct are provided with several transition grooves that communicate with the filtration space, and the several air outlet grooves provided on the inner wall of the rear end of the reinforced duct are all facing the first dust filter.

[0010] Preferably, a wind deflector is provided on the outer rear end of the bottom of the air intake slot, and the top of the wind deflector is fixedly connected to the bottom surface of the front anti-collision beam body. The wind deflector assists in guiding the air entering the air intake slot.

[0011] Preferably, the inner wall of the rear end of the wind deflector is coplanar with the inner wall of the rear end of the air intake groove to avoid structural interference. The top structure of the wind deflector is fixed to the bottom surface of the front anti-collision beam body by welding. The two side corners and the bottom corner of the wind deflector are all set as rounded corner structures to avoid assembly scratches.

[0012] The reinforced plate adopts a wave-folded structure, and the top and bottom of the reinforced plate are fixed to the bottom inner wall and top inner wall of the front anti-collision beam body, respectively. The corner structures of the front and rear ends of the reinforced plate are fixedly connected to the inner walls of the front and rear ends of the front anti-collision beam body, respectively. The reinforced plate can fully improve the structural strength of the front anti-collision beam body, and can also deform and absorb energy along with the front anti-collision beam body during subsequent large impacts, reducing the damage caused by the impact.

[0013] Specifically, a second dust filter is nested and fixed inside the air outlet groove to perform secondary dust filtration on the air entering the car. The rear surface of the second dust filter is coplanar with the rear surface of the front bumper beam body to avoid structural interference and maintain the aesthetics of the overall structure.

[0014] An automobile includes a front body frame and the aforementioned front anti-collision beam assembly. The rear ends of two energy-absorbing boxes are respectively installed on both sides of the front end of the front body frame, and the rear end structure of the energy-absorbing box is fixed to the corresponding front end side structure of the front body frame by screws, which ensures the strength and stability of the structural connection and also creates favorable conditions for subsequent disassembly and maintenance.

[0015] Specifically, the front end of the vehicle body front compartment frame is provided with several auxiliary mounting plates. These auxiliary mounting plates are arranged and installed along the circumference of the front anti-collision beam body, which facilitates subsequent installation operations and creates favorable conditions for the integrated connection and use of the front anti-collision beam body and the vehicle body front compartment frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model uses a reinforcing plate and a first dust filter to form a multi-functional front bumper beam assembly with an air inlet and outlet slot inside the front bumper beam body. In subsequent use, in addition to using the reinforcing plate and reinforcing duct to improve the deformation and energy absorption effect of the front bumper beam body and energy absorption box, the air output through the front bumper beam assembly is filtered by the first dust filter, which satisfies the ventilation and heat dissipation of the existing automotive components while preventing a large amount of dust from entering the area where the front frame of the vehicle body is located.

[0018] 2. This utility model, through the auxiliary device consisting of a wind deflector, a second dust filter, and a reinforced duct, and further combined with the aforementioned front anti-collision beam assembly, can utilize the wind deflector to buffer and guide the air flowing through the area where the air intake slot is located, thereby ensuring the air intake volume of the air intake slot during operation. The second dust filter, together with the first dust filter, performs multiple filtrations on the air in use. The reinforced duct and the multiple transition grooves opened inside the reinforced duct can ensure the air intake slot's air output performance while strengthening the structural strength of the front anti-collision beam.

[0026] 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.

[0027] Please see Figure 1-4 The front bumper beam assembly and the automobile include a front bumper beam body 1 and energy-absorbing boxes 2 installed on both sides of the rear end of the front bumper beam body 1. The front bumper beam body 1 is internally fitted with a reinforcing plate 4, and the inner wall of the reinforcing plate 4 is provided with a clearance groove. A first dust filter 5 is nested in the clearance groove, and a filtering space is formed between the first dust filter 5, the reinforcing plate 4, and the front inner wall of the front bumper beam body 1. The bottom of the front bumper beam body 1 is provided with an air intake groove 6 that communicates with the transition space. The rear end space of the front bumper beam body 1 communicates with the filtering space, and the rear end structure of the front bumper beam body 1 is provided with an air outlet groove 8 that communicates with its own rear end space.

[0028] The reinforcing plate 4 adopts a wave-folded structure, and the top and bottom of the reinforcing plate 4 are fixed to the bottom inner wall and top inner wall of the front anti-collision beam body 1, respectively. The corner structures of the front and rear ends of the reinforcing plate 4 are fixedly connected to the inner walls of the front and rear ends of the front anti-collision beam body 1, respectively. The reinforcing plate 4 can fully improve the structural strength of the front anti-collision beam body 1, and can also deform and absorb energy along with the front anti-collision beam body 1 during subsequent large impacts, reducing the damage caused by the impact.

[0029] In use, after a car suffers a frontal impact, the front bumper beam body 1, the energy-absorbing box 2, and the reinforcing plate 4 installed inside the front bumper beam body 1 will deform and absorb energy, thereby reducing the damage to the car as a whole.

[0030] During normal vehicle operation, the air entering the front compartment through the existing air intake grille can enter the filter space through the air intake slot 6. After being filtered by the first dust filter 5, the air can be discharged to the rear end area of ​​the front anti-collision beam body 1 through the air outlet slot 8, thereby meeting the ventilation and heat dissipation requirements of the cooling module.

[0031] Please see Figure 1-2The air intake slot 6 is fitted with a reinforcing duct 7. The top of the reinforcing duct 7 is fixedly connected to the top inner wall of the front anti-collision beam body 1. The reinforcing duct 7 is used to improve the structural strength of the air intake slot 6 and the area near the air intake slot 6. Several transition grooves that communicate with the filter space are opened in the inner walls of the front and rear ends of the reinforcing duct 7. Several air outlet grooves set on the inner wall of the rear end of the reinforcing duct 7 are all facing the first dust filter 5.

[0032] In use, considering that the opening of the air intake slot 6 will weaken the strength of the front end structure of the front bumper beam body 1 to a certain extent, the reinforcement duct 7 is set to compensate for this. Moreover, the reinforcement duct 7 itself has multiple transition slots, which can ensure the air output of the air intake slot 6 while strengthening the structural strength of the front bumper beam body 1.

[0033] Please see Figure 3-4 A wind deflector 10 is provided on the outer rear end of the bottom of the air intake slot 6, and the top of the wind deflector 10 is fixedly connected to the bottom surface of the front anti-collision beam body 1. The wind deflector 10 assists in guiding the air entering the air intake slot 6. The inner wall of the rear end of the wind deflector 10 is coplanar with the inner wall of the rear end of the air intake slot 6 to avoid structural interference. The top structure of the wind deflector 10 is fixed to the bottom surface of the front anti-collision beam body 1 by welding. The two side corners and the bottom corner of the wind deflector 10 are all set with rounded corners to avoid assembly scratches.

[0034] During use, considering the air intake efficiency of the air intake slot 6, the baffle plate 10 is used to buffer and guide the air flowing through the area where the air intake slot 6 is located, thereby ensuring the air intake volume of the air intake slot 6 during operation.

[0035] Please see Figure 1 The air outlet 8 is internally nested with a second dust filter 9, which performs secondary dust filtration on the air entering the car. The rear surface of the second dust filter 9 is coplanar with the rear surface of the front anti-collision beam body 1 to avoid structural interference and maintain the aesthetics of the overall structure.

[0036] In order to further reduce the dust content of the air used in the heat dissipation process, the second dust filter 9 works in conjunction with the first dust filter 5 to perform multiple filtration processes on the air during use, thereby reducing the adverse effects of subsequent dust on other components inside the car.

[0037] Please see Figure 5-6 An automobile includes a front body frame 3 and the aforementioned front anti-collision beam assembly. The front sides of the front body frame 3 are respectively installed with the rear ends of two energy-absorbing boxes 2. The rear end structure of the energy-absorbing box 2 and the corresponding front side structure of the front body frame 3 are fixed by screws to ensure the strength and stability of the structural connection and to create favorable conditions for subsequent disassembly and maintenance.

[0038] The front end of the vehicle body front compartment frame 3 is provided with several auxiliary mounting plates 11. The several auxiliary mounting plates 11 are arranged and installed along the circumference of the front anti-collision beam body 1, which facilitates subsequent installation operations and creates favorable conditions for the integrated connection and use of the front anti-collision beam body 1 and the vehicle body front compartment frame 3.
