Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumpers, in particular to a new energy electric four-wheel vehicle bumper. Background Art

[0002] The car bumper is installed at the front and rear ends of the car. It not only has a decorative function, but also has a safety device that can absorb and mitigate external impact, protect the car body and the safety of the passengers. The existing car bumper is fixed to the car by welding or other methods, which makes it difficult to remove the bumper when repairing the car, which brings trouble to the repair work.

[0003] To this end, the utility model patent with publication number CN220220657U discloses an easily disassembled automobile bumper, which belongs to the technical field of automobile bumpers, and includes a main body and a fixed frame, wherein protruding piles are symmetrically welded on the inner side of the main body, and a fixing seat is symmetrically welded on the side of the fixing frame facing the main body, and slots are formed on the two fixing seats on the side facing the main body, and two protruding piles are respectively inserted into the two slots in the horizontal direction, and movable grooves are formed on the tops of the two slots toward the two fixing seats, respectively. The top wall of each movable groove is symmetrically connected with springs, and the two springs are connected with limiting blocks below, and the top wall on the side where the protruding pile is inserted into the slot is provided with a notch, and the bottom of the limiting block is inserted into the notch, and a handle is fixedly connected to the limiting block. The easily disassembled automobile bumper can be completely separated from the fixed frame by pulling the two handles at the same time so that the two limiting blocks release the restrictions on the two protruding piles, thereby realizing convenient disassembly of the main body;

[0004] However, during actual use, we found that when using the above-mentioned bumper, the disassembly part requires the staff to manually pull up the handle part, and the handle part is located inside the front bumper of the vehicle, resulting in a small operating space for the staff and making the lifting action more troublesome. Therefore, it is necessary to consider how to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a new energy electric four-wheel vehicle bumper.

[0011] Preferably, a limiting groove is provided at the upper end of each connecting strip located in the slot.

[0012] Preferably, the lower end of each magnetic limiting block extends into the corresponding limiting groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] A first spring is provided. When an external impact occurs, the impact force will be buffered by the elastic action of the first spring and then transmitted to the fixed frame. This can effectively buffer the impact force and make the bumper more protective. When the main part of the bumper needs to be disassembled, it is only necessary to start the two electromagnets and energize them to attract the magnetic limit block to move upward, so that the main part can be removed and the electromagnet can be turned off after replacing it. Compared with the existing disassembly and installation methods, this method is simpler. BRIEF DESCRIPTION OF THE DRAWINGS
