Description
Technical Field
[0001] The utility model relates to the technical field of anti-collision for new energy vehicles, and specifically relates to an automatic anti-collision protection device for new energy vehicles. Background Technique
[0002] Since the birth of the automobile, it has become an indispensable and important tool for the development of human society, greatly breaking through the time and space limitations of human travel. With the continuous development of technology, automobiles are divided into fuel vehicles and new energy vehicles. New energy vehicles, with their advantages such as low emissions, energy conservation and high efficiency, have an increasing market share.
[0003] The power system of new energy vehicles is significantly different from that of traditional fuel vehicles. The large-capacity power batteries installed in them have safety hazards such as fire and explosion during collisions, which pose higher requirements for the anti-collision protection structure of the vehicle. Therefore, an anti-collision protection device for new energy vehicles is proposed.
[0004] Chinese Utility Model Patent Publication No.: CN219077156U, discloses: an automobile anti-collision protection device. This automobile anti-collision protection device effectively protects the front end of the main beam of the automobile through the combination of the first support plate, the second support plate, the protection plate, the groove, the sliding groove, the sliding plate, the force-releasing plate and the buffer spring, avoiding the phenomenon of large deformation of the main beam of the automobile when a collision occurs. Moreover, it is convenient for the cooperation of the force-releasing plate and the buffer spring to buffer the collision force, preventing the phenomenon of huge deformation of the protection plate when the automobile collides, and reducing the danger of the automobile during a collision. However, this automobile anti-collision protection device does not design a side collision protection strengthening structure. When a side collision occurs, it is easy to cause deformation, resulting in serious deformation during the collision. Summary of the Invention
[0005] The technical problem to be solved by the utility model is to provide an automatic anti-collision protection device for new energy vehicles, which can effectively solve the problems in the prior art.
[0006] The technical solution adopted by the utility model is: an automatic anti-collision protection device for new energy vehicles, including an anti-collision cross beam, connecting rods at both ends of the anti-collision cross beam, and airbag ejection parts on one side close to the connecting rods. A reinforcing plate is fixedly installed at the end of the anti-collision cross beam far from the connecting rods. Reinforcing frames are inserted and installed at both ends of the anti-collision cross beam far from the center line. An extension plate and a fixed frame are fixedly installed at the other end of the anti-collision cross beam far from the connecting rods. A reinforcing cross beam made of steel is welded at the other end of the anti-collision cross beam far from the extension plate and the fixed frame. Reinforcing rods are welded on one side of the anti-collision cross beam close to the reinforcing cross beam and far from both ends of the anti-collision cross beam.
[0007] Preferably, the cross-section of the anti-collision cross beam is in an "arc" shape structure, and two through grooves are opened in the anti-collision cross beam through the reinforcing plate.
[0008] Through the above technical solution, with the anti-collision crossbeam in an "arc" shape, when being impacted, the arc-shaped surface can better disperse the impact force. Combined with the design of the through slots, when being impacted, certain stress can be reduced, avoiding harm to the vehicle occupants.
[0009] Preferably, reinforcing frames are inserted and installed on the inner surfaces of both of the through slots. The reinforcing frames are all made of steel and are provided with two identical groups. Each group of the reinforcing frames has two identical ones and is symmetrically distributed about the center line of the anti-collision crossbeam.
[0010] Through the above technical solution, the reinforcing frames made of steel have high strength and rigidity. After being inserted into the through slots, the structural strength of the anti-collision crossbeam can be further enhanced. When being side-impacted, the reinforcing frames can jointly bear the impact force with the anti-collision crossbeam, disperse the impact force to the entire anti-collision structure, improve the anti-deformation ability of the anti-collision crossbeam, prevent it from undergoing serious deformation during the collision, and thus better protect the vehicle occupants.
[0011] Preferably, a clamping slot is formed at one end of the connecting rod close to the anti-collision crossbeam. The clamping slot is adapted to the anti-collision crossbeam, and a positioning plate is fixedly installed at the other end of the connecting rod away from the anti-collision crossbeam.
[0012] Through the above technical solution, during a vehicle collision, the connecting rod can transmit the impact force borne by the anti-collision crossbeam to other parts of the vehicle, further disperse the impact force, and at the same time ensure that the anti-collision crossbeam will not easily fall off during the collision.
[0013] Preferably, the cross-section of the extension plate is in an "L" shape structure. A positioning bolt is provided at the other end of the extension plate away from the anti-collision crossbeam. The extension plates and the positioning bolts are provided with the same number of them and are equally spaced.
[0014] Through the above technical solution, one end of the "L" shape structure of the extension plate is fixedly connected to the anti-collision crossbeam, and the other end is fixed to other components of the vehicle through the positioning bolts. Moreover, the design of multiple and equally spaced extension plates and positioning bolts can improve the connection stability between the anti-collision crossbeam and the vehicle.
[0015] Preferably, an airbag ejection member is fixedly installed at the other end of the reinforcing crossbeam away from the anti-collision crossbeam, and an airbag body is provided at the output end of the airbag ejection member.
[0016] Through the above technical solution, after receiving the collision signal, the airbag ejection member quickly activates the internal triggering device, causing the airbag body to inflate and pop out in a very short time. When colliding with a pedestrian, the impact force received by the pedestrian can be reduced, thereby improving the practicability of the overall protection device.
[0017] Preferably, infrared detectors and sensors are provided at both ends of the airbag ejection member away from the center line and located on the reinforcing cross beam. An installation groove is formed at the other end of the reinforcing rod away from the anti-collision cross beam, and a reserved hole is formed through the end of the fixed frame close to the anti-collision cross beam.
[0018] Through the above technical solution, during normal driving of the vehicle, the airbag ejection member is in a standby state. When the vehicle collides, the sensor and the infrared detector detect the collision signal and transmit the signal to the airbag ejection member, which can facilitate the identification of pedestrians or collision objects.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] Embodiment 1: As Figures 1-6 shown, a new energy vehicle automatic anti-collision protection device provided by the present invention includes an anti-collision crossbeam 1, connecting rods 5 at both ends of the anti-collision crossbeam 1, and an airbag ejection member 14 on one side close to the connecting rod 5. A reinforcing plate 2 is fixedly installed at one end of the anti-collision crossbeam 1 away from the connecting rod 5. Reinforcing frames 4 are inserted and installed at both ends of the anti-collision crossbeam 1 away from the center line. An extension plate 8 and a fixed frame 11 are fixedly installed at the other end of the anti-collision crossbeam 1 away from the connecting rod 5. A reinforcing crossbeam 13 made of steel is welded at the other end of the anti-collision crossbeam 1 away from the extension plate 8 and the fixed frame 11. Reinforcing rods 10 are welded on one side of the anti-collision crossbeam 1 close to the reinforcing crossbeam 13 and away from both ends of the anti-collision crossbeam 1.
[0031] Specifically, the cross-section of the anti-collision crossbeam 1 is in an "arc" shape structure. The anti-collision crossbeam 1 is provided with two through grooves 3 through the reinforcing plate 2. The advantage is that with the "arc" shaped anti-collision crossbeam 1, when being hit, the arc surface can better disperse the impact force. Combined with the design of the through groove 3, when being hit, the anti-collision crossbeam 1 can deform, thereby reducing a certain amount of stress and avoiding harm to the vehicle occupants.
[0032] Specifically, reinforcing frames 4 are inserted and installed on the inner surfaces of both through grooves 3. The reinforcing frames 4 are all made of steel and are provided with two identical groups. Each group of reinforcing frames 4 has two identical ones and is symmetrically distributed about the center line of the anti-collision crossbeam 1. The advantage is that the steel reinforcing frames 4 have high strength and rigidity. After being inserted into the through grooves 3, they can further enhance the structural strength of the anti-collision crossbeam 1. When being side-collided, the reinforcing frames 4 can jointly bear the impact force with the anti-collision crossbeam 1, disperse the impact force to the entire anti-collision structure, improve the anti-deformation ability of the anti-collision crossbeam 1, and prevent it from deforming severely during the collision, thus better protecting the vehicle occupants.
[0033] Specifically, a clamping groove 6 is formed at one end of the connecting rod 5 close to the anti-collision cross beam 1. The clamping groove 6 is adapted to the anti-collision cross beam 1. A positioning plate 7 is fixedly installed at the other end of the connecting rod 5 far from the anti-collision cross beam 1. The advantage is that when the vehicle collides, the connecting rod 5 can transfer the impact force borne by the anti-collision cross beam 1 to other parts of the vehicle, further dispersing the impact force and ensuring that the anti-collision cross beam 1 will not fall off easily during the collision.
[0034] Embodiment 2: As Figures 2-6 shown, as an improvement over the previous embodiment.
[0035] Specifically, the cross-section of the extension plate 8 is in an "L" shape. A positioning bolt 9 is provided at the other end of the extension plate 8 far from the anti-collision cross beam 1. The extension plate 8 and the positioning bolt 9 are provided in the same number and are equally spaced. The advantage is that one end of the "L" shape of the extension plate 8 is fixedly connected to the anti-collision cross beam 1, and the other end is fixed to other components of the vehicle through the positioning bolt 9. The design of multiple and equally spaced extension plates 8 and positioning bolts 9 can improve the connection stability between the anti-collision cross beam 1 and the vehicle.
[0036] Specifically, an airbag ejection member 14 is fixedly installed at the other end of the strengthening cross beam 13 far from the anti-collision cross beam 1. An airbag body 17 is provided at the output end of the airbag ejection member 14. The advantage is that after receiving the collision signal, the airbag ejection member 14 quickly activates the internal triggering device, causing the airbag body 17 to inflate and pop out in a very short time. When colliding with a pedestrian, it can reduce the impact force received by the pedestrian, thereby improving the practicality of the overall protection device.
[0037] Specifically, an infrared detector 15 and a sensor 16 are provided at both ends of the airbag ejection member 14 far from the center line and located on the strengthening cross beam 13. An installation groove 18 is formed at the other end of the strengthening rod 10 far from the anti-collision cross beam 1. A reserved hole 12 is formed through the end of the fixed frame 11 close to the anti-collision cross beam 1. The advantage is that during normal driving of the vehicle, the airbag ejection member 14 is in a standby state. When the vehicle collides, the sensor 16 and the infrared detector 15 detect the collision signal and transmit the signal to the airbag ejection member 14, which can facilitate the identification of whether it is a pedestrian or a collision object.
[0038] Working principle: When in use, through the anti-collision crossbeam 1 with an "arc" shape structure, when being impacted, the arc-shaped surface can better disperse the impact force. With the design of the through groove 3, when being impacted, it can cause the anti-collision crossbeam 1 to deform when being impacted, thereby reducing a certain amount of stress and avoiding harm to the vehicle occupants. The reinforcing frame 4 made of steel has high strength and rigidity. After being inserted into the through groove 3, it can further enhance the structural strength of the anti-collision crossbeam 1. When being side-impacted, the reinforcing frame 4 can bear the impact force together with the anti-collision crossbeam 1, disperse the impact force to the entire anti-collision structure, improve the anti-deformation ability of the anti-collision crossbeam 1, and prevent it from deforming severely during the collision process, so as to better protect the vehicle occupants. When the vehicle collides, the connecting rod 5 can transmit the impact force borne by the anti-collision crossbeam 1 to other parts of the vehicle, further dispersing the impact force, and at the same time ensuring that the anti-collision crossbeam 1 will not fall off easily during the collision process. One end of the "L"-shaped structure of the extension plate 8 is fixedly connected to the anti-collision crossbeam 1, and the other end is fixed to other components of the vehicle through the positioning bolt 9. Moreover, the design of multiple extension plates 8 and positioning bolts 9 distributed at equal intervals can improve the connection stability between the anti-collision crossbeam 1 and the vehicle. After receiving the collision signal, the airbag ejecting member 14 quickly activates the internal triggering device, causing the airbag body 17 to inflate and pop out in an extremely short time. When colliding with a pedestrian, it can reduce the impact force received by the pedestrian, thereby improving the practicability of the overall protection device. During the normal driving process of the vehicle, the airbag ejecting member 14 is in a standby state. When the vehicle collides, the sensor 16 and the infrared detector 15 detect the collision signal and transmit the signal to the airbag ejecting member 14, which can facilitate the identification of whether it is a pedestrian or a collision object.
[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
