Description

Technical Field

[0001] This utility model relates to the field of bumper frames, specifically a front bumper frame that can carry detection equipment. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear components of the vehicle. With the continuous development of lightweight automotive design, the design of lightweight safety structures and material alternatives for car bumpers has become a key research focus. Traditional car bumpers are primarily made of metal. Using lightweight, impact-resistant metal alloys in the bumper panel can improve the energy absorption efficiency of the bumper panel during low-speed impacts.

[0003] Chinese Patent Publication No. CN212954964U discloses a car bumper made of thermoplastic composite material. This utility model provides a car bumper using thermoplastic resin as the matrix and carbon fiber reinforced composite material. The bumper has a front panel, crossbeam, supporting frame, and foam material made of impact-resistant composite material, rigid composite material, and energy-absorbing material, respectively. The front panel and crossbeam effectively improve the bumper's impact resistance and deformation resistance through different carbon fiber designs and weaving structures. The three-dimensional composite material frame energy-absorbing sandwich layer in the middle effectively improves the bumper's impact energy absorption efficiency, ensuring overall impact resistance and safety.

[0004] When the car bumper of the aforementioned patent is equipped with a detection device, if the bumper collides with other objects, the bumper will deform due to the collision. The deformed bumper may squeeze the detection device, causing damage to the detection device. Utility Model Content

[0005] The purpose of this utility model is to provide a front bumper frame that can carry a detection device. The bumper frame has a through hole, and a limit cover is provided at the rear end of the through hole. A fixed base connected by a spring is located at the bottom of the limit cover. A connecting post for the detection device is mounted on the fixed base. Multiple protective claws connected by spring-loaded hinges are provided on the outer surface of the connecting post. When the bumper frame deforms due to an impact and presses against the detection device mounted on the connecting post, the spring contracts under external force, causing the connecting post to retract into the limit cover. The protective claws on the outer surface of the connecting post retract along with the connecting post into the limit cover. During this retraction, the protective claws contact the wall of the through hole, closing and protecting the connecting post with the installed detection device. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front bumper frame capable of carrying a detection device, comprising a front frame, a through hole on the front frame, a limit cover at one end of the through hole, and a fixed base, the fixed base having the bottom end of the limit cover, a spring on the fixed base, a connecting base at the end of the spring away from the fixed base, a connecting post on the connecting base, and a spring-loaded rotating hinge on the outer surface of the connecting post.

[0007] Preferably, the movable end of the spring-loaded hinge is provided with a protective claw, which is bolted to the spring-loaded hinge.

[0008] Preferably, the connecting column has a detection device mounting hole on the end away from the connecting base, and the detection device mounting hole is integrally formed with the connecting column.

[0009] Preferably, the outer surface of the limiting cover is provided with a sliding groove, and the sliding groove is integrally formed with the limiting cover.

[0010] Preferably, the connecting base is provided with a limiting block at the corresponding position of the slide groove, and the limiting block is integrally formed with the connecting base.

[0011] Preferably, the front frame is provided with side baffles at both ends, and the side baffles are integrally formed with the front frame.

[0012] Preferably, a connecting block is provided on the side baffle, and the connecting block is integrally formed with the side baffle.

[0013] Preferably, the connecting block has a reserved bolt hole, and the reserved bolt hole is integrally formed with the connecting block.

[0014] Preferably, the front-end frame is provided with a connecting block, and the connecting block is integrally formed with the front-end frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a through hole in the front frame, with a limit cover at the rear end of the through hole. A spring-loaded fixing base is located at the bottom of the limit cover, and a connecting post for a detection device is mounted on the fixing base. Multiple protective claws connected by spring-loaded rotating hinges are located on the outer surface of the connecting post. When not impacted, the connecting post extends beyond the horizontal plane of the front frame. Upon impact, the spring pulls the connecting post, carrying the detection device, back into the limit cover. As the connecting post retracts, the spring-loaded rotating hinges contact the wall of the through hole, causing the originally open protective claws on both sides to close, protecting the connecting post within the claws. This effectively avoids the problem of existing car bumpers deforming upon collision with other objects, potentially damaging the detection device. Attached Figure Description
