Description

Technical Field

[0001] The utility model relates to the technical field of bumpers, in particular to an energy-absorbing elastic automobile bumper. Background Art

[0002] Bumpers are important safety features installed at the front and rear ends of a car. Their primary function is to absorb and mitigate external impacts, protecting the car body and its occupants. Bumpers not only serve a decorative purpose but also protect the car body in the event of a collision, reducing repair costs.

[0003] The development of automobile bumpers has undergone a material change from metal to plastic. Early bumpers were made of metal, but metal bumpers were not aesthetically pleasing and had poor applicability. With the development of industry, the outer panels and cushioning materials of automobile bumpers are now made of plastic.

[0004] However, the structure of this bumper is too simple, and after the bumper is shattered by a collision, it directly acts on the energy absorption box or the car's anti-collision beam. The bumper with this structure does not cause too much problem when a collision occurs between vehicles. However, if a vehicle hits a pedestrian, or a pedestrian is squeezed between two vehicles, and the bumper is shattered, the human body will directly hit the car's anti-collision beam. The anti-collision beam is made of metal material and does not have the ability to cushion and protect the human body, which makes the human body extremely vulnerable to injury.

[0005] Therefore, it is necessary to invent an energy-absorbing elastic automobile bumper to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an energy-absorbing elastic automobile bumper to solve the above-mentioned deficiencies in the technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an energy-absorbing elastic automobile bumper, comprising a bumper outer skin, a base provided on the back of the bumper outer skin, a plurality of evenly distributed buffer mechanisms provided on the front of the base, an airbag fixedly mounted on the front of the base and located between the plurality of buffer mechanisms, with both ends of the airbag close to one side of the buffer mechanism;

[0008] The buffer mechanism comprises:

[0009] A connecting seat is fixedly mounted horizontally on one end of the front face of the base, and a through-type guide hole is vertically opened near the front end of the connecting seat;

[0010] The jacket is sleeved on the front end of the connecting seat, a screw is vertically installed at the tail end of the jacket, the lower end of the screw passes through the guide hole of the connecting seat, and partition pieces are fixedly installed on both sides of the tail end of the jacket.

[0011] As a preferred solution of the present invention, the front end of the jacket is fixedly connected to the back of the bumper outer skin, the partition piece is made of a metal sheet, and a plurality of notches are formed on both sides of the partition piece.

[0012] As a preferred solution of the present invention, an aluminum alloy plate is fixedly mounted on the back of the bumper outer skin, and a buffer pad is embedded and mounted between the bumper outer skin and the aluminum alloy plate.

[0013] As a preferred solution of the present invention, protective plates are fixedly installed above and below the front surface of the base, the airbag is located between the two protective plates, and the width of the protective plates is smaller than the width of the airbag.

[0014] As a preferred solution of the present invention, a groove is provided transversely inside the connecting seat, the front end of the groove is connected to the guide hole, a spring is fixedly installed transversely in the groove, and the front end of the spring is connected to the screw.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] By providing an airbag and a buffer mechanism, the bumper's buffer mechanism effectively absorbs impact forces during a collision, reducing damage to the vehicle body and occupants, as well as pedestrians. The airbag also acts as a buffer during the collision, further alleviating pedestrian damage. It also rapidly breaks the partition, facilitating the rotation of the jacket. This energy-absorbing elastic bumper offers significant advantages in safety, energy absorption, material selection, structural design, applicability, cost advantages, and aesthetics, helping to improve vehicle safety during driving.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides Figure 1-5 The energy-absorbing elastic automobile bumper shown includes a bumper outer shell 1. A base 8 is provided on the back of the bumper outer shell 1. A plurality of evenly distributed buffer mechanisms 5 are provided on the front of the base 8. The buffer mechanisms 5 provide the bumper with good elasticity and reduce the impact effect. An airbag 4 is fixedly mounted on the front of the base 8 and located between the plurality of buffer mechanisms 5. The two ends of the airbag 4 are close to one side of the buffer mechanism 5.

[0027] The buffer mechanism 5 includes:

[0028] The connecting base 6 is fixedly mounted horizontally on one end of the front side of the base 8, and a through-type guide hole 61 is vertically opened near the front end of the connecting base 6;

[0029] The jacket 7 is sleeved on the front end of the connecting seat 6, and a screw rod 71 is vertically installed at the tail end of the jacket 7. The lower end of the screw rod 71 passes through the guide hole 61 of the connecting seat 6, and partition pieces 72 are fixedly installed on both sides of the tail end of the jacket 7.

[0030] Furthermore, in the above technical solution, the front end of the jacket 7 is fixedly connected to the back of the bumper skin 1, and the partition piece 72 is made of a metal sheet. There are multiple notches on both sides of the partition piece 72. The partition piece 72 of this structure can break quickly when it receives impact force, which facilitates the rotation of the jacket 7.

[0031] Furthermore, in the above technical solution, an aluminum alloy plate 3 is fixedly installed on the back of the bumper skin 1, and a buffer pad 2 is embedded and installed between the bumper skin 1 and the aluminum alloy plate 3, thereby playing a certain buffering role.

[0032] Furthermore, in the above technical solution, protective plates 9 are fixedly installed above and below the front of the base 8, and the airbag 4 is located between the two protective plates 9. The width of the protective plate 9 is smaller than the width of the airbag 4. The airbag 4 helps to disperse the collision force and improve the protection performance of the bumper, while the protective plate 9 can protect the upper and lower ends of the airbag 4. In order to prevent the impact force from impacting the front when the airbag 4 ruptures, a rubber pad can be added to the front of the airbag 4 to improve the protection effect, and when the airbag 4 ruptures, the impact force can be dispersed to both ends, so that the impact force can effectively impact the partition piece 72.

[0033] Furthermore, in the above technical solution, a groove 62 is transversely opened inside the connecting seat 6, the front end of the groove 62 is connected to the guide hole 61, a spring 63 is transversely fixedly installed in the groove 62, and the front end of the spring 63 is connected to the screw 71. The spring 63 can produce elastic deformation during collision and absorb impact force, which is beneficial to the deformation and recovery of the spring 63.

[0034] The energy-absorbing elastic automobile bumper provided by the utility model has the following working process when in use:

[0035] The bumper is installed as a whole to the front end or rear end of the vehicle. When the vehicle collides, the bumper skin 1 will be squeezed first. If it is a minor collision, the bumper skin 1 made of plastic will be deformed by the force, and its own elasticity makes it not easy to be damaged. When the collision effect increases, that is, the collision effect causes the bumper skin 1 to shatter, the buffer pad 2 on the back of the bumper skin 1 plays a certain buffering role and absorbs the energy of the received impact force, and then acts on the aluminum alloy plate 3. At this time, the impact force will not cause the aluminum alloy 3 to shatter. When the collision effect further increases, that is, the impact force causes the aluminum alloy plate 33 to break, the aluminum alloy plate 3 squeezes the buffer mechanism 5 on the back thereof. Since the spring 63 installed in the connecting seat 6 of the buffer mechanism 5 has a certain buffering effect, and the guide hole 61 provided on the connecting seat 6 provides a certain distance for the rearward movement of the jacket 7, the combination of the two also plays a certain buffering role.

[0036] If the collision effect is stronger, the jacket 7 drives the aluminum alloy plate 3 and the bumper skin 1 to move backward to the maximum position, and the broken aluminum alloy plate 3 squeezes the airbag 4 on the front of the base 8, and the sharp parts of the broken aluminum alloy plate 3 directly puncture the airbag 4. After the airbag 4 is broken, its impact force will impact to both ends and directly act on the partition pieces 72 on both sides of the jacket 7. The partition pieces 72 are broken by the force, and as the aluminum alloy plate 3 squeezes the jacket 7 to move backward on the connecting seat 6, due to the uneven force during the collision at this time, the jacket 7 is rotated on the connecting seat 6 through the screw 71, thereby achieving a further buffering effect and reducing the harm to pedestrians.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
