Description

Technical Field

[0001] This utility model belongs to the field of charging equipment technology, and specifically relates to a charging protection device for new energy vehicles. Background Technology

[0002] With the rapid popularization of new energy vehicles, the safety and durability of charging piles, as a core supporting facility, are becoming increasingly prominent issues. In real-world usage scenarios, accidents involving vehicles colliding with charging piles due to reversing errors, driver blind spots, or slippery ground are frequent. These accidents can range from minor damage to the charging pile's outer casing and internal components to more serious hazards such as electrical leakage and fire. While existing charging pile protection technologies have seen some improvements, the following key shortcomings still exist:

[0003] The buffer structure is simple, resulting in low energy absorption efficiency. Traditional protective devices often use a single-layer rubber pad or simple spring as the buffer medium, with limited material compressibility (usually below 40%) and a lack of multi-stage energy dissipation design. Impact energy is concentrated in a single structure, easily causing instantaneous overload failure of the buffer layer. The remaining kinetic energy is directly transferred to the charging pile body, leading to structural damage. The mechanical decomposition capability is insufficient, and the impact redundancy is low. Existing protective frames mostly use rigid structures with vertical or horizontal layouts (such as steel supports), which can withstand some impact, but do not optimize the vector decomposition path of the force. For example: insufficient material strength: the yield strength of ordinary aluminum alloys (such as 6061 type) is only about 280MPa, making them prone to plastic deformation or even fracture under high-speed impact. Lack of angled guiding design: the impact force is transmitted to the charging pile base in a straight line, lacking inclined guide rails or mechanical decomposition mechanisms, making it impossible to offset the impact energy through force components. Utility Model Content

The assembly includes a movable frame, a lifting cylinder, a reinforcing frame, a limiting rod, a reinforcing rod, a mounting plate, an airbag, a buffer spring, a limiting groove, and a return spring. The limiting rod is embedded in both sides of the inner wall of the base platform. The movable frame is slidably fitted onto the outer wall of the limiting rod. The lifting cylinder is fixedly located at the top of the outer wall of the movable frame. The limiting groove is located on both sides of the top of the outer wall of the base platform. The movable frame is slidably embedded into the inner wall of the limiting groove. The reinforcing frame is slidably embedded into the inner wall of the lifting cylinder. One end of the reinforcing rod is fixedly located at the top of the outer wall of the movable frame, and the other end is fixedly located on one side of the outer wall of the reinforcing frame. The mounting plate is slidably inserted into the corner opening of the outer wall of the reinforcing frame. The airbag is adhesively attached to one side of the outer wall of the mounting plate. The buffer spring is fitted onto the outer wall of the protruding end of the mounting plate. The return spring is fitted onto the outer wall of the limiting rod.

[0012] Furthermore, a reflective layer is sprayed onto one side of the outer wall of the airbag.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] High compression ratio energy absorption: Utilizing a honeycomb-shaped arrangement of polymer airbags (65% compression ratio), it absorbs over 80% of the initial impact kinetic energy through three-dimensional deformation, significantly reducing direct impact force. Reflective warning design: The airbag surface is coated with a reflective layer to improve visibility at night or in low-light environments, assisting drivers in accurately locating charging stations. A tiered energy dissipation mechanism: Primary buffer: A return spring (matching the moving frame) absorbs low-to-medium intensity impacts, initially dissipating energy through elastic deformation. Secondary buffer: A buffer spring (sleeved onto the mounting plate) intervenes during high-intensity impacts, forming a progressive resistance with the return spring to avoid stress concentration. The mounting plate constraint design and the extended structure at the protruding corners ensure a stable deformation path for the buffer springs, preventing displacement and failure.

[0029] In a specific embodiment of this utility model, a high compression ratio energy absorption system is implemented using a honeycomb-arranged polymer airbag 9 (compression ratio 65%).

[0030] Specifically, a charging pile body 2 is fixedly installed on one side of the outer wall of the base 1.

[0031] In a specific embodiment of this utility model, the charging pile body 2 can ensure the convenience of charging.

[0032] Specifically, the return spring 601 is matched with the movable frame 3.

[0033] In a specific embodiment of this utility model, the return spring 601 is matched with the movable frame 3 to ensure buffering of the movable frame 3 and avoid impact.

[0034] Specifically, the protruding ends at the corners of the mounting plate 8 extend outwards.

[0035] In a specific embodiment of this utility model, the protruding end at the corner of the mounting plate 8 extends outward to ensure the constraint and limitation of the buffer spring 10.

[0036] Specifically, the inner wall of the limiting groove 101 is embedded with a rubber layer.

[0037] In a specific embodiment of this utility model, the inner wall of the limiting groove 101 is embedded with a rubber layer to prevent moisture and debris from falling in.

[0040] Working principle:

[0041] First, the base platform 1 is placed in a depression in the ground, making it slightly higher than the ground. By pouring a ramp, the vehicle is aligned with the base platform 1 along the ramp. Then, the vehicle is reversed so that it is facing the airbag 9. The vehicle continues to start, moving against the airbag 9, which moves the reinforcement frame 5 and the moving frame 3 on the limit rod 6. When the vehicle moves uncontrollably, the moving frame 3 impacts the reset spring 601, and at the same time, the buffer spring 10 disperses the force points to prevent the vehicle from directly impacting the charging pile body 2.
