Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumpers, in particular to an automobile bumper with a protective structure. Background Art

[0002] The car bumper is an important component installed at the front and rear ends of the car. As the first line of defense in the event of a vehicle collision, it can reduce the damage to the vehicle body and components caused by the collision. In low-speed collisions, it prevents direct damage to the vehicle body and reduces repair costs. In pedestrian collision accidents, the special design reduces the degree of injury to pedestrians. Car bumpers play an important role in protecting the safety of vehicles and pedestrians and optimizing vehicle performance and appearance.

[0003] The traditional automobile bumper structure is relatively simple, and due to the limitation of the vehicle body length, the bumper's buffering stroke is generally short when a collision occurs, and the buffering force is insufficient during a collision, making the traditional automobile bumper less safe when in use. After searching, it was found that the technical solution provided by the utility model with application number CN202223049911.2 also has the above-mentioned problems. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a car bumper with a protective structure. When the bumper is hit, the first spring and the damper are used in conjunction to ensure that the impact force on the bumper can be smoothly transitioned and buffered, thereby avoiding serious damage to the vehicle body structure and occupants caused by the instantaneous strong impact. In addition, the shock-absorbing protection mechanism can disperse the impact force laterally, reducing the impact force on the passengers in the car, providing better protection for the passengers, enhancing the safety performance of the vehicle in a collision accident, improving the safety of the car bumper, and reducing the degree of serious damage to local locations.

[0005] To achieve the above-mentioned objectives, the utility model also provides a car bumper with a protective structure as described above, including: a bumper and a shock-absorbing protection mechanism, the inner surface of the bumper is fixedly connected to a first buffer plate, the rear surface of the first buffer plate is fixedly connected to a first rubber buffer pad, the rear surface of the first rubber buffer pad is fixedly connected to a top plate, the rear surface of the top plate is fixedly connected to a damper, the rear surface of the top plate is fixedly connected to a first spring, the rear end of the first spring is fixedly connected to the bottom plate, the rear surface of the top plate is fixedly connected to a connecting block, the shock-absorbing protection mechanism includes a first turntable, a movable rod, a second turntable, a movable block and a second spring, the upper surface of the connecting block is fixedly connected to the first turntable, the upper surface of the first turntable is rotatably connected to the movable rod, the front surface of the bottom plate is fixedly connected to a support block, the right surface of the support block is fixedly connected to the guide rod, and the rear surface of the bottom plate is fixedly connected to the second buffer plate.

[0006] According to the automobile bumper with a protective structure, the rear end of the damper is fixedly connected to the base plate, and the damper passes through the interior of the first spring. The first spring can store and release energy. When impacted, the first spring compresses to absorb energy, and the damping reduces the rebound speed and amplitude of the first spring, preventing excessive vibration of the spring, thereby achieving smoother and more effective shock absorption.

[0007] According to the automobile bumper with a protective structure, the lower surface of the movable rod is rotatably connected to the second turntable, and the lower surface of the second turntable is fixedly connected to the moving block.

[0008] According to the automobile bumper with a protective structure, the right end of the second spring is fixedly connected to the movable block, and the left end of the second spring is fixedly connected to the support block. The top plate is subjected to an impact force which is transmitted to the connecting block, the movable rod, and the movable block. Under the action of the guide rod, the movable block moves toward both ends, dispersing the impact force laterally, thereby achieving a shock-absorbing effect.

[0009] According to the automobile bumper with a protective structure, the rear surface of the second buffer plate is fixedly connected to the second rubber buffer pad, the guide rod passes through the interior of the second spring, and the second buffer plate and the second rubber buffer pad further play a buffering role.

[0010] According to the automobile bumper with a protective structure, the rear surface of the second rubber buffer pad is fixedly connected to a connecting plate, and the inner surface of the moving block is slidably connected to the guide rod.

[0011] According to the automobile bumper with a protective structure, the front surface of the bumper is fixedly connected to an anti-collision strip, and the front surface of the anti-collision strip is fixedly connected to anti-collision elastic particles. The anti-collision strip and the anti-collision elastic particles can first bear the impact force when the vehicle has a minor collision, reduce the direct impact on the bumper, and thus reduce the degree of damage to the bumper.

[0012] According to the automobile bumper with a protective structure, the number of the anti-collision elastic particles is multiple and linearly distributed, and the number of the damper and the first spring is multiple.
